The invention relates to nozzles for tanks solvent for adjustable cooking time extraction of a beverage, in particular for tea, with a support plate for attachment to the opening capacity of the solvent, and the base plate has a through hole for passing capacity of extractable substance, and a lifting device is provided that includes a sleeve, which is held the container of extractable substance so that this capacity at the lower end stands for the sleeve and may be filled through the top opening of the sleeve of extractable substance, and the lifting device is fixed relative to the base plate guiding device, which is installed with sleeve the possibility of displacement in a substantially vertical relative to the base plate in the linear guide between the lower and upper position and lower position specifies the brewing position of the sleeve, in which a container of extractable substance is omitted, and the upper position defines a neutral position in which the container of extractable substance is elevated relative to the brewing position, and the lifting device has a locking device to lock the sleeve in the brewing position, and there is a timer, which is first performed to actuate the locking device so after expiration of the preset time interval, the sleeve is released, if it is fixed in the brewing position. Further, the invention relates to a teapot with such a nozzle, the timer includes a control element for setting a time interval.

US 2006/A (Yang Heng-Te) refers to a device for an adjustable time tea, which after a pre-set time "welding" (tea herb) can be separated from tea (drink). For this purpose, the device includes a main body, which stands on the capacity for solvent condition above includes a timer, which by rotation around the vertical axis can be set time interval. Simultaneously with the setting of the time interval, in particular, in the first Executive section of the timer located under the main part of the tank for tea goes down and is locked in this position. Upon expiration of the time interval capacity for tea is released, after which the container for tea goes up lifting device. Thus, the mechanism of the lifting device makes it possible that the capacity for tea to fill should otvincivatmisa from rigidly connected to the lifting device filter lid, to which the device with katsa with capacity for solvent. Filled the tank for tea then again screwed onto the filter cover, and then the device again can be mounted on the tank for the solvent. As a consequence, the manipulation device is difficult because the lling of tea due to removing the unit from the tank to the solvent. In addition, screwing containers for tea with the filter cover can often be difficult and prone to contamination by penetrating into the thread of the tea herb.

DE 19839421 A1 (Jens Gerber Joerg) is a small sieve, mesh filter element is mounted on the lid of the sieve of time by means of a mechanical or electrical actuator telescopically moved into closed under the sieve capacity. Raising and lowering of the mesh of the filter element is achieved by means of a screw sleeve with inside screw threads and threaded finger under the sieve capacity. Under the sieve capacity made with the possibility of filling from the top through the cover sieves tea with grass, while a fine sieve mounted on the container for the solvent. Thus, DE 19839421 A1 (Jens Gerber Joerg) though and offers convenient fillable tea sieve, but because of the helical groove has a relatively labor-intensive design of the lifting device. The AOC is e, due to the large friction losses in the screw sleeve has a powerful and thus expensive spring-loaded mechanism. Not in the last turn of the screw sleeve is susceptible to contamination tea with grass, so that the device may be blocked and thus is functionally unreliable.

Therefore, the object of the invention is the creation of related to the above first technical area nozzle for a container for a solvent for adjustable cooking time extraction of the drink, which by simple manipulation is reliable and economical.

The solution to this problem is determined by the signs of paragraph 1 of the claims. According to the invention, the nozzle for a container for a solvent for adjustable cooking time extraction of a beverage, in particular for tea, and has a support plate for sitting on the hole capacity of the solvent, and the support plate has an aperture for the passage of tanks for extractable substances. Next, there is a lifting device that includes a sleeve, which retained the capacity for extractable substances so that it is at the lower end stands for the sleeve and may be filled extractable substance through the top opening of the sleeve. When this lifting device includes still is relative to the reference plate guiding device, fitted sleeve with a possibility of displacement in a substantially vertical relative to the base plate in the linear guide between the lower and upper position and lower position specifies the brewing position of the sleeve, in which the capacity for extractable substances is lowered, and the upper position sets the neutral position, in which the capacity for extractable substances is elevated relative to the brewing position. Further, the lifting device includes a locking device to lock the sleeve in the brewing position. In addition, there is a timer, which is designed to actuate the locking device so that upon expiration of the preset time interval, the sleeve is released, if it is in the brewing position. According to the invention, the sleeve is in the brewing position is loaded along the linear guide return force, which returns it from the brewing position to the neutral position when the sleeve is released.

The support plate is provided for draping on the capacity of the solvent. Typically, the capacity of the solvent during the preparation time is on the horizontal support so that the solvent remained in the vessel. Thus,the top reference edge of the tank for solvent, which restricts the opening to sitting heads, as a rule, is substantially horizontally, in connection with which the support plate is generally horizontal. Of course, the support plate can also sit down on the tank for the solvent, which is located on an inclined plane. Further, in relation to the horizontal in the broadest sense of the location of the support plate on the container for solvent relative concepts as "below" and "above" refer to the location of the nozzle in operational and horizontal location on the container for the solvent. The term "vertical" in this sense also applies to the substantially horizontal support plate and thereby largely identigene the concepts of "vertical relative to the base plate direction" or "axial", unless otherwise stated. In this case, the top-down direction determined by the direction of gravity.

Fundamentally, the support plate may be of any shape, which, however, allows the nozzle to the hole capacity of the solvent. In this case, the side of the support plate in mounted on the container for solvent condition is addressed to the capacity of the solvent. Typically, the support plate is made essentially flat and largely in the her the periphery of the hole lays on the support edge of the tank to the solvent. Described next part of the nozzle is preferably located on the side of the support plate, which lies opposite the side of the vessel.

Preferably, the support plate has a circumferential sidewall with a radially curved edge to support the nozzle on the support edge of the tank to the solvent. This achieves a particularly stable retention of the nozzle on the container for the solvent. If curved region is located higher relative to the support plate, the support plate is lowered into the inner space of the vessel for solvent, so that the center of gravity of the nozzle is low and thus leads to better retention. Additionally, the curved edge can also serve as a mounting surface for the cover (see below). The support plate can be performed without special edge and lean on top of the anchor edge of the tank to the solvent. In this case, preferably provided by the speakers down stops, which prevent radial displacement of the nozzle relative to the capacity of the solvent.

The nozzle may be provided, for example, a holder in the form of a clip or other fastening means for fixing the nozzle to the vessel for solvent. Finally, the cap-type cover maker can be pivotally connected to the container for the solvent. Preferably, the size of the nozzle is aligned with the relevant is Noah for her capacity for solvent. In one embodiment, the nozzle may also be shaped so that it can use different containers for solvent, particularly pitchers, cups, etc. may be provided, for example, a tapered wall on the periphery of the support plate, which supports putting the nozzle on various holes.

The aperture in the base plate is preferably in the plane of the plate and creates a passage in axial, i.e. vertical to the reference plate direction. Lifting device located at the opening is preferably stationary relative to the support plate, and the sleeve is located for movement in substantially vertical relative to the base plate direction coaxially with the aperture. Thus, the lifting device provides rise, respectively, lowering held on the sleeve capacity for extractable substances through the opening in a substantially vertical relative to the base plate direction. For this, the size of the aperture is selected so that the capacity for extractable substances and, if necessary, the sleeve can move freely through the opening. In particular, the opening has essentially corresponding to the periphery of the capacity for extractable substances, respectively, of the sleeve periphery. Thus, the capacity for extractable what about the substance and, if necessary, the sleeve can in the axial direction to pass through the doorway without the need of existence from the periphery of the significant distances between the capacity for extractable substances accordingly, the sleeve and the periphery of the opening.

The sleeve is made open at both longitudinal ends, preferably cylindrical, in particular in the form of a right circular cylinder, the longitudinal axis of which is coaxial with the vertical support plate, preferably with an average vertical support plate, and in this case, the center of the aperture is also centered relative to the reference plate.

Capacity for extractable substances retained in the sleeve in such a way that it is, for example, telescopically acting through the lower opening of the sleeve. Capacity for extractable substances is open on top so that it is held on the sleeve condition may be filled through the top opening of extractable substance, for example, tea grass. Thus, the capacity for extractable substances can convenient way to fill a teaspoon grass, while the nozzle is mounted on the container for the solvent.

According to the invention, a lifting device for axial lifting and lowering includes a relatively stationary base plate guiding device on which the sleeve is mounted for displacement in a substantially vertical relative to the base plate in the straight linear guide between the bottom and the top is orogenies. In this case, the routing device may include, for example, fixed relative to the support plate rails or rods, which are arranged vertically relative to the base plate and on which is installed with the possibility of moving the sliders sleeve. Guiding device can also include stationary relative to the support plate, the guide sleeve, in which is installed with the possibility of telescopic movement of the sleeve lifting device.

The path of movement of the sleeve in the guide device is preferably defined by two stops. In impaled on a tank of solvent, ready for use condition of the nozzle upper stop of the sending device determines the neutral position of the sleeve, and the lower stop - tea position. If all guiding device is turned on from the tank to the solvent side of the support plate, the lower stop is located closer to the base plate and the upper end farther from the support plate. In the neutral position, the sleeve is displaced in the guide device to the upper limit, resulting in held in the sleeve capacity for extractable substances lifted through the opening relative to the support plate. In the brewing position, the sleeve is shifted to the lower extreme position so that the capacity for extractable ve is esta lowered through the aperture in the inner space of the vessel for solvent.

Locking device lifting device is designed in such a way that the sleeve, when it is in the brewing position, preferably automatically locked in this position. The timer works and interacts with the locking device in such a way that it can trigger lock after a preset time interval, whereupon the sleeve is released. In this case, the timer may be positioned stationary relative to the base plate or may be mounted on the sleeve, for example, in the form of a cap, or, respectively, can be integrated into the sleeve.

According to the invention, the sleeve is in the brewing position loaded along the linear guide return force. Thus, held on the sleeve capacity for extractable matter when the release sleeve by means of a timer upon expiration of the preset time interval, a simple way is automatically displayed, respectively, rises from the inner space of the reservoir for the solvent. In particular, the linear guide allows a direct impact return efforts, resulting, on the one hand, the lifting movement can be carried out in a simple way. On the other hand, a relatively small return effort is up to the adjusted as must be applied only linear effects without significant friction losses, as in the case of an inclined or helical guide. Preferably, the sleeve all the way move loaded return force. Thus, during lowering of the sleeve from the neutral position in the brewing position against the action returns the efforts of Executive energy can accumulate (accumulate) and used to return to the neutral position. However, due to the rectilinear direction of Executive energy optimally consumed and may, at the maximum current of the lifting path is also optimal re-converted to return. As the lifting device also includes a sleeve, which has a capacity for extractable substances, as described above, due to this is obtained simply fill in any position nozzle for a container for a solvent that has a simple and reliable design.

Preferably returning force provided by the elastic element, which acts between the support plate and the sleeve. The elastic element comprises preferably a spring, in particular a helical spring, a predominantly helical compression spring. This achieves a particularly simple and cost-effective implementation in the torque effort. Of course, the elastic element can be made differently, for example in the form of a rubber band, spring tension, twisted Flexural springs or the like. The spring relative to the sleeve can be made from the side or the district. When the lateral placement of the spring is provided preferably several, in particular, at least two symmetrically arranged spring, so it can be prevented distortion of the sleeve. Preferably, the nozzle includes a guide for the spring, and one element of this guide is rigidly connected with the sleeve, and the other element is rigidly connected with the support plate. Guide springs are preferably made from the sending device or has a separate linear guide. Preferably, the sleeve or support plate includes an axially oriented pin, which is at least partially embedded in the set by means of the spring interior space. Support plate, respectively, the sleeve preferably includes a guide sleeve for the spring, which may at least partially be entered spring. This ensures that the hard direction of the spring, in particular this can be prevented flexing of the spring. Of course, you can also abandon bushing guide for the spring.

Returns an effort could before the given due to the counterweight, in particular, in the form of a lever guide.

Preferably, the capacity for extractable substances are designed to insert into the sleeve, and the upper area includes a flange as a one-sided emphasis. Thus the capacity for extractable substances are particularly well can be captured by the consumer and be removed by hand from the bushing. Similarly, the capacity for extractable substances may particularly simple manner be entered by the user into the sleeve from the top. This allows easy use of nozzles and is also favorable, in particular, for users, and motor are limited, as, for example, the capacity for extractable substances shall not be screwed or otherwise difficult to gain a foothold. Preferably, the capacity for extractable substances in the area of the flange is slightly larger in diameter than the sleeve, so that the capacity for extractable substances may particularly well be captured. Further, the flange on the outer side may include radially surrounding the grooves which may be prevented from sliding off during capture. If necessary, this may be enough when the flange only in certain parts of acts radially beyond the sleeve. Capacity for extractable substances made essentially in the form of C is covered with one side of a circular cylinder and includes in the lower pane in the supporting surface and/or on the ring side, the holes through which the solvent can join and lead. However, preferably, if the capacity for extractable substances has openings both at the bottom and the side, so that when immersed in the solvent, it may well take place through the internal space of the vessel for extractable substances. Capacity for extractable substances retained in the sleeve preferably without the possibility of twisting. This can be achieved, for example, through located on the district side of the tank for extractable substances, in particular under the flange protruding radially outward protrusions and corresponding located on the inner wall of the grooves in the upper region of the sleeve. Of course, the protrusions and recesses can also be swapped.

Emphasis can be implemented, for example, by guiding the key-groove, and the groove has a bottom stop. Thus, at the same time could be implemented fixation against rotation between the capacity for extractable substances and sleeve.

Preferably capacity for extractable substances includes a mesh part and the retaining part, and the mesh part is made to lock the coaxial in a holding part at several axial positions. In this case, this is why the emphasis is made on the holding part, which is thus given emphasis longitudinal position is inserted into the sleeve. As the capacity for extractable substances made with the possibility of locking the sleeve in different longitudinal positions, thereby depending on the filling level in the tank for solvent can adjust the depth of immersion tanks for extractable substances. In particular, this nozzle can also be used for differently designed containers for solvent. Fixation can be achieved through locking protrusions and grooves.

Capacity for extractable substances can also be made with the possibility of screwing into the sleeve so that axial position can be achieved by rotation, and position in the axial direction is fixed by frictional closure or locking tabs. Of course, the retaining part and a mesh part can be made as well as made in one piece insert.

Capacity for extractable substances especially in the transition from the neutral position in the brewing position of the sleeve moves from the top through the opening. In this case, the components of the lifting device are primarily based essentially on facing to the vessel for solvent side of the support plate. In this case, the capacity of the DL is extracted substance is inserted from above into the sleeve so that this capacity when lowering the sleeve in the brewing position through an aperture is provided in the inner space of the vessel for solvent, when the nozzle is mounted on the container for the solvent. Thus further simplifies the manipulation of the nozzle, as when mounted on the container for the solvent nozzle can be made as a lling for extractable substances and lowering without the necessity of removing the nozzle from the tank to the solvent.

Preferably, the capacity for extractable substances made with the possibility of lowering from the neutral position in the brewing position, directly by the user against the direction of action of the return efforts, where (tea) position the sleeve is automatically locked. To do this, the user has oriented essentially in the axial direction of the force on capacity for extractable substances and thus directs it downwards against the action of return efforts, which is implemented, for example, by springs (see above). Of course, the sleeve may also indirectly, for example, additional Executive arm, to fall in the brewing position.

As the capacity for extractable substances are retained on the sleeve, it goes down together with the sleeve, after which the blocking at trojstvo blocks in the brewing position of the sleeve and with it the capacity for extractable substances. Preferably simultaneously with the actuation by the user is used to overcome the return of the efforts of Executive energy accumulated in the energy accumulator, which later required to raise the capacity for extractable substances after the expiration of the time interval. Thus, battery power is provided by an elastic element, e.g. a spring, which exerts a return force. Thus, the energy accumulator accumulates Executive energy and allows it to extract to raise the sleeve.

Preferably, in the case of this nozzle all structural elements of the lifting device located relative to the axial direction on the outside of the sleeve. Thus, the tea herb can easily be entered through the grommet in the tank for extractable substances without any structural part of the lifting device prevented the filling. Thus, the tea grass when filling tanks for extractable substances through the grommet can't even get in touch with a lifting device and, for example, to pollute it, respectively, in extreme cases, block or damage it. Thus, preferably, the lifting device can fit completely as possible the existing floor body (see below) nozzles, pre is respectfully substantially hermetically placed in the nozzle, so lifting device is also protected from common contaminants, such as dust, etc. and, if necessary, against splashing water. In addition, the lifting device thus can be protected from misuse, respectively, manipulation, and thus is reliable and can be made compact.

Preferably, the guiding device includes available on the support plate at the opening of the guide sleeve, which is equipped with the ability to move the sleeve, and the inner space of the guide sleeve communicates with the aperture of the support plate and at least partially accepts preferably in a neutral position capacity for extractable substances. With such a guide sleeve can largely be prevented distortion of the sleeve and provided with an optimally controlled longitudinal guide. Guide Bush is made preferably in one piece with the support plate, but can also be connected with the support plate in a different way. Preferably, the bushing goes on the guide sleeve to prevent from turning. This can be achieved, for example, by a rod or slider. The rod can be axially oriented, preferably, on the outside of the sleeve is connected with the support plate, pricematch includes in the form of a slider in the lower region of the protruding radially outward protrusions with the guide holes, moreover, the rod can go in these holes. Thus can be simultaneously realized return force due to the fact that the helical compression spring is located around the rod. Of course, the terminal can also be connected with the sleeve and the slide - support plate. Further, guide Bush, for example, also may include a guide groove, and the sleeve is respectively performed ledge, or Vice versa. Further, the guide sleeve and the sleeve can be made not in the form of a circular cylinder, as, for example, respectively in the form of a cylinder with a polygonal or oval bearing surface, and the guide Bush and the capacity for extractable substances have the appropriate forms. Thereby simultaneously achieved preventing twisting (rotation) of the sleeve relative to the guide sleeve. Instead of the guide sleeve can also be provided by other guides tools. So, for example, can be provided with guide pins, the guide rails and/or cylindrical shell with a generatrix in the form of an arc of a circle.

Preferably, the sleeve forms an essentially circular pipe. It is thereby possible simple introduction capacity for extractable substances in the sleeve. Namely, by a circular run of the sleeve provides the highest who is ona degree of freedom of relative axial rotation capacity for extractable substances in the introduction of it into the sleeve.

Preferably, the sleeve is made double-walled, and the intermediate space between the double wall of the bottom is open, and the top is substantially closed. The sleeve preferably is located on the inversion for the guide sleeve so that the guide sleeve at least in the brewing position is located in the intermediate space between the double wall. Thus, the outer wall may influence return force, while the capacity for extractable substances may be taken by the inner wall and the top edge. This achieves a particularly simple transfer return force between the support plate and the sleeve. The axial height of the guide sleeve preferably is slightly higher than the speed of lifting of the lifting device, which is the direction of the sleeve at each longitudinal position along the guide. Of course, the sleeve need not necessarily be performed with circumferential double wall. For example, the double wall may be provided only in certain areas or sleeve has only internal wall, and the guide sleeve is sent (installed) telescopically.

Preferably, the guiding device includes stationary relative to the support plate, the guide rails or guide rods, which offers the wife vertically relative to the base plate and on which the sleeve is installed with the possibility slides his bent outward, arranged stationary relative to the sleeve, made in the form of flange projections. Thereby separately or in addition to the guide sleeve achieves reliable direction of the sleeve.

Preferably, the locking device has an actuating element, which is designed and located in such a way that he, in particular, in the brewing position of the sleeve, can interact with the timer. This locking device includes preferably one connected with the supporting plate element and the other connected to the sleeve element, which locking sleeve preferably includes at each other. Preferably, at least one of these elements are in the form element, respectively, provided with actuating element and is mounted movably and/or spring. The elements are made and located so that they are in the locked position blocking movement of the sleeve in a longitudinal guide in at least one direction.

A blocking device is preferably supported on a support plate, in particular, mounted rotatably, the first locking hook, which is made in such a way that it is fixed with a locking element sleeve when the sleeve is in the brewing position, and the locking element sleeve which engages a second locking hook, which, in particular, is rigidly connected with the sleeve, preferably preferowan to it, and, in particular, the actuating element includes a lever arm, which is connected with the first locking hook. Thus, there is a particularly simple locking device. The first locking hook is located can be rotated preferably in the peripheral region of the sleeve and radially relative to it. In the area of the axis of rotation, in particular above the axis of rotation, the first locking hook includes a locking protrusion, which is oriented essentially horizontally and which is even omitted when the sleeve is on the outside of the sleeve. The first locking hook is connected with an actuating element, which is made in the form of an elongated portion which is oriented essentially axially. The actuating element is moved radially inward, preferably relative to the first locking hook so that it is omitted when the sleeve is at least partially between the two walls of the sleeve, if it is made double-walled. Thus, the actuating element acts on the axis of rotation axially upward. The bushing on the lower edge of the outer wall includes a protruding radially outward of the second locking hook, which is oriented tangentially to the sleeve and horizontally and placed with circumferential sides is so, he can interact with the first locking hook is in the lowered condition, in particular, can block the sleeve down. When in this locked position the actuating element is rotated, the sleeve is released and returns through the efforts of the moves up. The sleeve may also have a protrusion or a recess, which may include located on the support plate can be rotated through a tangential axis of the locking hook. The specialist is also known for other possibilities of how you can make similar locking device.

Preferably, the first locking hook is loaded return force so that the locking element sleeve is automatically locked locking hook when the sleeve is in the brewing position. The first locking hook returns through efforts is held in the neutral position, which corresponds to the engaged position in a locked state. Return force is provided, preferably, by means of a spring, in particular through the twisted Flexural springs. It is thereby possible easy maintenance of the nozzles, since blocking is automatically triggered when the brewing position. In addition, the specialist known other elastic elements, whoalso suitable for a return force (rubber band, a tension spring, etc).

The first and second locking hooks are acting as the control surface of the bevel, so that the contact locking hooks first made with the possibility of rotation of the locking hook is deflected against its return efforts and achieve the brewing position locking snap hooks. To release the sleeve, the actuating element is moved against the return efforts, resulting in the first locking hook that is attached to the Executive element, derived from the state of engagement with the second locking hook, and thus the engagement of the locking hooks removed.

The timer preferably has a triggering element, which during the course of the preset time interval substantially continuously moved and after a preset time interval interacts with the actuating element of the locking device so that the sleeve is released, if it is in the brewing position. The triggering element is designed and ready for operation the system is located relative to the actuating element of the locking device so that when he reaches the preset time interval can rotate the contractor is the first element against his return effort i.e. to operate the locking device, and thus to release the sleeve.

Substantially continuously moving the triggering element provides a structurally simple execution timer as, for example, the minute movement axis normal to the mechanism can be transmitted directly to the triggering element. Thus, actuation of the blocking device after a preset time interval occurs only as a result of a suitable relative positioning of the actuating element of the locking device relative to the path of movement of the triggering element. However, this does not exclude the fact that the triggering element is moved only after a time interval. Depending on the timer, the movement can also occur in discrete steps. The Executive element in other embodiments, stationary, for example, the hinge may be attached to the timer, respectively, to the trigger element.

Preferably the actuating element of the locking device reaches the upper edge region of the sleeve when the sleeve is in the brewing position. This, in particular, is an advantage when the timer is preferably in the form made with the possibility of removal of a cover which has a capability n is taiwania on the top opening of the vessel for extractable substances. As the Executive element is given in the upper edge region of the sleeve, thus the timer is a simple way to interact with the locking device directly in the upper edge region of the sleeve. Other functional parts of the blocking device can be performed at a distance from him in the area of the support plate, where there is relatively a lot of space and good installation. In addition, performed by, for example, in the form of an elongated lever element, which is mounted on a support plate, is achieved that the timer, respectively, the triggering element due to the leverage effect, only a small force must provide to the Executive element of the blocking device to be actuated locking device. As a result of execution of the timer in the form made with the possibility of removal of the cover is achieved especially user-friendly design, as a timer, for example, when cleaning the nozzles can be removed. Preferably the cover is made with the possibility of removal at any time, even during the brewing process, when the preset time interval has expired, if should be supplemented, for example, the extracted substance. Further, when made with the possibility of removal of the timer there is a possibility you will offer is it as a replacement part without having to replace the entire nozzle failure.

Preferably, the actuating element of the locking device, in particular in the brewing position, is located at least partially in the intermediate space between the two walls made of double-walled sleeve, whereupon the actuating element substantially capsulized and protected from maltreatment, as well as from pollution.

Preferably, the triggering element of the timer is made in the form made with the possibility of rotation of the element, in particular in the form of an installed rotatably around the axis of rotation of the lever. During the current time interval triggering element rotates in this case, around the axis of rotation, which when planted cover, respectively, the timer is preferably axially, in particular, coaxial capacitance for extractable substances. The cover preferably includes an Executive element of the timer to set the desired time frame, and the actuating element when planted cover is made preferably by a coaxially oriented relative to the axis of rotation of the rotary switch. Triggering element in parallel is located in the lower region of the cover and radially protrudes from the bottom diameter of the cover. The triggering element can be directly associated with the movement of the rotary switch, or, for example, through the transmission of decreasing or increasing the reduction ratio. Triggering element can also be made in the form of rotationally installed in the vertical plane of the element, which acts in the upper edge region of the sleeve and thus may result in action by the Executive member. The timer, however, does not necessarily have to be made in the form of cover, and can also be located, for example, the stationary base plate. In this case, the actuating element is not up to the upper edge region of the sleeve, and expedient way is in the path of movement of the triggering element of the timer.

Preferably, the actuating element of the locking device is in the notch in the upper edge region of the sleeve, which is also triggering a timer, if the timer is mounted on the sleeve, and the recess is open, in particular, upward, so that the triggering element can be removed from the notch up when the timer is removed from the sleeve. The path of movement of the triggering element is limited mainly by the area of the excavation. Preferably, the actuating element of the locking device in the brewing position of the sleeve is located in the azimuthal end region of the grooves. Thus, the actuating element only after a pre-sadava the CSOs of the time interval, i.e. at the end of the trajectory, is actuated by the triggering element. Of course, that the relative location of the element at the end of the path of movement of the triggering element even at other locations of the blocking device and the timer provides a simple way to ensure actuation of the blocking element only after a preset time interval.

When the double-walled implementation of the sleeve, the recess preferably made only on the inner wall of the sleeve. In this case, perhaps the existing guide Bush guide device is mostly a corresponding recess, which is a complete overlap with the notch of the sleeve when the sleeve is in the brewing position. Thus, the triggering element of the timer may be located inside the sleeve and the actuating element of the locking device on the outside of the guide sleeve and, consequently, the interaction of both elements. In particular, the triggering element in the radial direction stands out as the inner wall of the sleeve and the guide sleeve and thus its trajectory covers the Executive element, if it is, for example, between the two walls of the sleeve, which made the double-walled. In this case, the actuating element is largely protected from external interference and therefore can decrease the risk of damage to the locking device. If the actuating element is located outside the outer wall of the sleeve, the recess preferably also covers the outer wall of the sleeve, so that the triggering element passes through the notch and can result in the movement of the actuating element timer.

Preferably intended for sitting on the tank of the solvent side of the support plate is made substantially equal, but opposite side of the support plate is covered with a hemisphere (spherical bowl), so between the support plate and the hemisphere is obtained hollow body, in which fully or partially allocated components of the longitudinal rail and the lifting device. In particular, the opening of the support plate continues the hemisphere, so that the sleeve within the specified due to longitudinal rail movement, in particular, in the neutral position, may extend upwards from the hemispheres, respectively, to speak for her. Hemispherical overlap mechanics nozzle protects it from damage and makes the nozzle aesthetically appealing shape. The hemispherical shape has moreover the advantage that the spray water well stack the t and thus pollution is reduced, and cleaning is simplified. Since the sleeve is in the neutral position advocated hemisphere, the capacity for extractable substances can especially easy to retrieve up or boot extractable substance, if the nozzle is mounted on the container for the solvent.

In addition, by extension, is achieved in that the sleeve serves as an actuating element for lowering capacity for extractable substances. The user sleeve available in case of need cover just presses down in the hemisphere up until sleeve snaps into place in the brewing position. Of course, that the overlap does not need to be made in the form of hemispheres, however, preferably it is convex, essentially rotationally symmetrical shape. If the sleeve is locked in the brewing position, then, for example, by made in the form of a rotary knob element located in the lid of the timer can be set preset time interval. Result returns the efforts of the sleeve extends rectilinearly up and ready for a new trigger.

Preferably, the blocking device is additionally configured to actuate by means of a separate control element, with which BC is the freezing sleeve can be removed manually so the user brewing process can be interrupted prematurely. Preferably, the nozzle is made essentially of a polymeric material, to provide hygienic cleaning. Of course, that the components of the timer or possibly available spring may include a metal. In this respect, the expert is known to a large number of suitable materials.

The invention also provides a teapot, which includes the capacity for solvent and nozzle according to the above description. In particular, the nozzle is mounted on the opening capacity of the solvent, so that in the brewing position of the sleeve lifting device capacity for extractable substances is lowered into the corresponding solvent, usually water, the internal space of the vessel for solvent, so that the capacity for extractable substances in the standard amount of solvent is immersed in the solvent. In the neutral position capacity for extractable substances largely extracted from the internal space. However, the capacity for extractable substances should not be completely removed from the internal space, and preferably elevated, at least, so that when a standard amount of solvent, the internal space is about the capacity for the extracted substance was slightly lowered in the solvent.

In the second aspect of the invention concerns, even apart from the above-mentioned embodiments, other attachment capacity of the solvent for adjustable cooking time extraction of a beverage, in particular the teapot for brewing tea. The device includes a support plate for sitting on the tank solvent tank for extractable substances, and also mounted on the base plate lifting device for containers for extractable substances, and the lifting device is designed and positioned relative to the capacity of the solvent so that the lifting device can lift capacity for extractable substances from omitted in the internal space of the vessel for solvent condition, when the nozzle as provided mounted on the container for the solvent. Next, the second aspect has a locking device for locking and releasing the lifting device is lowered, the capacity status for extractable substances, as well as a timer that can interact with the locking device so that the lifting device after a preset time interval is released. When this timer shall have an Executive element with the Executive direction to bring into action the s timer the timer, in addition, includes a mechanical energy accumulator for accumulating spent on the Executive element of the Executive power and within the preset time interval provides battery power. This locking device includes a first element and second element, and during preparation, extraction drink one of the two elements is stationary relative to the capacity of the solvent, and the other is stationary relatively to the capacity for extractable substances, and the first and second elements are interacting with each other so that the first element by the second element during the preset time interval slidably directed through the second element in the second actuating direction, and after a preset time interval in the first Executive direction.

Thus created another way to implement a nozzle for adjustable time extraction drink, which (way) is easy to maintain and economical to manufacture.

According to the second aspect of the invention is achieved by the fact that simultaneously with the actuation element of the timer in the first Executive direction the AI tank for extractable substances may fall into the inner space of the vessel for solvent, and can also be charged the first part of the energy accumulator. Further, by the subsequent actuation element of the timer in the second actuating direction can be charged another part of the battery, and can also set the time interval of the timer. In this case, the first Executive direction may differ from the second, resulting in the user intuitively already because of Executive direction is clear, lowered whether it is due to the actuation element timer capacity for extractable substances or activated if it is the timer and set the time interval.

Further according to the second aspect is achieved that both for lowering the capacity to brew substances, and to set a time interval can operate the same Executive element of the timer. Thus, installation, and maintenance of the device is simple and clear criteria.

In addition, through the first element by the second element according to the second aspect is achieved in that the actuating element of the timer is actuated sequentially in both the Executive directions, resulting in lowering of the capacity for extractable substances at the same time cannot mistakenly set the change time interval, and accordingly, on the contrary. This, in particular, also for users with less sensitive motor functions facilitates easy and at the same time reliable use of the device.

On the contrary, due to this, it also provides the ability to sequentially discharge the two parts of the energy accumulator, respectively, can be prevented parallel discharge. In particular, in both parts of the energy accumulator can accumulate different amounts of energy, which can be used largely independently of each other. Preferably each part of the battery energy provides energy for lifting device, respectively, the energy for the timer.

According to the second aspect during the current time interval, the blocking device blocks the first part of the energy accumulator. Upon expiration of the preset time interval is accumulated in the first part of the battery energy is released and is filed lifting device for lifting containers for extractable substances. The second part of the energy accumulator of the second aspect provides the energy for the timer, which selects accumulated in the second accumulator energy and uses it to measure the time interval that must elapse between the time of actuation time is RA and the lifting capacity of extractable substances. So, as usual in the second part of the energy accumulator should accumulate less energy than it would in the first part of the battery energy.

Preferably, the capacity for extractable substances of the second aspect of ready to use the location of the nozzle on the container for the solvent is removed by lifting device from the internal space of the reservoir for solvent so that the capacity for extractable substances for normal levels preferably completely removed from the solvent. Thus the extraction of the beverage, in particular, after draining the extracted substances are not yet able to concentrate more. In some embodiments, the capacity for extractable substances can be removed from the extraction of the beverage in significant part, so that the extraction drink then another only slightly concentrated. Capacity for extractable substances of the second aspect can also be made telescopically, so that the depth of immersion tanks for extractable substances may be adjusted to the level of solvent in the tank for the solvent. This capacity for extractable substances can be stretched and to close, at least up to two discrete lengths, or even continuously to arbitrary lengths.

According to the second aspect, the AK first part, and the second part of the battery energy is mechanical. Thus, essentially, not taking account of the possibly necessary heating of the solvent is achieved independence from external energy sources. It has not only the advantage that thereby - in the absence of external, for example, electric, energy source - can be prepared extraction drinks, but also that the nozzle can be safely cleaned without that needed to be considered, for example, with the risk of receiving an electric shock or damage to the device. Further, due to this, it becomes possible in a simple and economical design of the nozzle.

A preferred way, the mechanical energy accumulator of the second aspect includes a first spring which loads the spring force of the actuating element against the first timer Executive direction, so that the first spring when the actuation element timer is loaded in the first Executive direction. There is thus obtained an economical, simple and does not require frequent maintenance the design of the battery energy. In one particularly preferred embodiment, the voltage/loading of the spring is carried out by, for example, rectilinear, pressure loading, which makes the possible service through simple movements. Preferably, the Executive direction is straightforward.

In one embodiment of the second aspect of the mechanical energy accumulator can also be carried out pneumatically. For this example, the inner space of the vessel under pressure would be supplied excess or reduced pressure by the Executive element of the timer, and within a predefined time interval unloading of the internal space of the tank is to achieve (approximately) and ambient pressure. However, this design, as a rule, is more time consuming than running with spring, but depending on requirements, this may be the preferred option implementation.

Preferably, the first spring energy accumulator of the second aspect is made in the form of a helical spring. However, particularly preferred conventional commercially available helical springs made of spring steel, as they are cheap and available in almost any form and with any stiffness coefficient of the spring. The coil springs through its geometry is also particularly simple and compact can be integrated into the housing, in particular, several coil springs with different diameters can be placed in each other (in parallel), and occupied thus the Ohm volume corresponds to the largest volume, occupied the largest spring. Coil spring is particularly preferred if the first control element has a rectilinear direction. Thus, coil spring need not be made of spring steel, but may also be made of other alloys, or perhaps even of the polymer. Instead of the helical compression springs can also be used helical tension spring. A helical tension spring could be located, for example, so that the upper region of the helical tension spring is so connected with the upper region of the nozzle according to the second aspect, that the capacity for extractable substances may be injected into this area until being at the lower end of the stop and can then strain through pressure loading.

Similarly, as in the case described above, the coil spring, tension can use rubber bands, but which, as a rule, have less life than the coil spring. Hereinafter, may also be suitable for use of the flat spring example, wound in the form of coil springs. Fundamentally, is also valid for any other type of spring, such as a conical coil spring, a cylindrical springs, disc springs, etc. that can be combined in essentially random.

Preferably m is the mechanical energy accumulator of the second aspect includes a second spring, which loads the spring force of the Executive element of the timer in the second actuating direction, so that the second spring is strained when the actuation element of the timer in the second actuating direction.

The battery energy of the second aspect, which is loaded with a separate actuating element through successive actuation in two Executive directions, has the advantage that for the first part and the second part of the energy accumulator are separate springs. Thus, charging and discharging of battery power in both the Executive directions can be a easy way isolated from each other, and Executive direction, thus, are selected independently from each other. In addition, due to this, for various Executive directions can be used various types of springs or, at least, springs with different stiffness (elastic modulus). Thereby further achieved that, depending on the Executive direction of the subject use of force can be set differently by selecting springs. For example, due to this, the first part of the energy accumulator of the second aspect of the energetically more costly actions, such as lifting capacity for EXT the state of Thuringia substances may be provided by a coil spring with a relatively large stiffness coefficient, which is strained through a rectilinear compression (squeezing). On the other hand, for example, the second part of the energy accumulator of the second aspect of the timer may be in the form of smaller energy storage, which, for example, by turning the rotary button similar to the classic the Sands of the hourglass can be loaded against the spring with a slight stiffness coefficient of the spring.

Alternatively, the second aspect of the invention for both the Executive can use the same spring, i.e. the spring is the first part and the second part of the energy accumulator. But in General, due to various Executive directions this can comparatively complicate the implementation, since the spring force of the spring elements, as a rule, are dependent from each other in the tangential and axial direction.

Preferably, the second spring energy accumulator of the second aspect is made in the form of torsion springs. In this case, the torsional spring geometrically preferably be essentially in the form of a helical spring, preferably negligible low coefficient of stiffness of the spring in the axial direction. Thereby is achieved that the first and the second is rugini in the device can have the same geometric realization, but different action efforts. This results in the least possible amount of construction, as, for example, a coil spring may have a smaller diameter than the torsional spring, and thus may be located, for example, coaxially inside the torsion spring. Further, through the use of torsion springs is achieved that the second Executive direction, which is loaded second part of the energy accumulator may be rotational movement. But, essentially, it can also be used by a single spring at the same time as coil spring and as a torsional spring, as a result can save cost and space, and can also simplified the complexity of the design. In this case, the stiffness coefficient of the spring would be in axial direction is negligible small. Finally, can also be used in other known types of torsion springs, such as coil springs.

The preferred image of the first element of the second aspect includes a cylindrical section and a protruding element, while the second element is designed as a guide. The cylindrical section of the first element so interacting with made in the form of directing the second element that the cylindrical section is made with the possibility of axial movement and at the same time rotation. who eat the first item in any sequence may be driven in the first and second Executive direction. In particular, as a consequence, it is also possible simultaneous superimposed movement in the first and second Executive direction. Through the speaker element of the first element and the corresponding guide on the second element can be specified permissible direction of movement of the first element. Due to this, it is not excluded that several such protruding elements can be placed together with the corresponding guide, as a result will be achieved stable direction.

The protruding element in one particularly preferred embodiment of the second aspect is made in the form of a comb element, in particular in the form of studs, and guide in the form of a linear guide or groove, for example, rectangular or trapezoidal cross-section, or in the form of a unilateral emphasis or different in some areas. Next may be provided, in particular, if certain provisions are preferably fixed, the design in the form of prismatic pins. Depending on the direction of the force on the first element, respectively, if there is another extreme position, the guide may also be performed with only one hand. Preferably, the guide has several, in particular relative to both the Executive directions exactly two plots. The first and the Torah of both sections can have different directions of the guides, one of the sections may include several parallel guides. Because of several guides plots several functions can be consistently controlled by the same element. The first section, however, made in the form of a groove, in particular in the form of several parallel grooves, and the second section is in the form of at least one-sided emphasis.

In one embodiment, in order to achieve using the guide for more stability design, would be valid also equipped with odnotrahniki guides respectively formed spines (pins), such as a guide in the form of a dovetail. But this design should be taken into account that the friction is not too large, in particular, distortion of the guide should largely be interrupted.

The preferred way is made in the form of a second guide element of the second aspect includes the cylindrical section to the first element in the first Executive direction and at least one-sided emphasis to the first element in the second actuating direction. The cylindrical section of the first element is sent several possible types. On the one hand, through the m of the speaker element and the guide in particular, by means of the groove, as described above, and, on the other hand, by means of a cylindrical section of the guide, which interacts with the adjustment of the shape of a cylindrical section of the first element.

The cylindrical section of the guide and the cylindrical section of the first element allows arbitrary helical movement of the first element and the protruding element allows the direction of the first element in a through groove direction, in particular, in straight or spiral direction. The direction could also be implemented by means of axially spaced pins. Thus, due to the speaker element and the groove in the rest of any helical direction of the cylindrical section of the first element may be limited to a cylindrical section, in particular, a screw trajectory. In some embodiments, both the Executive direction can be set by a cylindrical section, or both, by at least one-sided emphasis.

Preferably made in the form of directing the second element of the second aspect includes at least one groove for guiding the speaker element of the first element in the first Executive direction. Mentioned, at least one groove may be made in the form of solely the first stop. In some embodiments, it is also possible to abandon the grooves and protruding element, resulting in the first element in the first Executive direction is directed solely through the cylindrical section of the guide.

Preferably, during preparation, extraction drink the protruding element of the second aspect regarding the capacity of the solvent and is designed as a guide the second element of the second aspect regarding the capacity for extractable substances are motionless. Due to this, easiest way are limited, respectively, are permissible movement capacity for extractable substances. Also, a valid stationary relative to the capacity for extractable matter the location of the speaker element, and stationary relative to the capacity of the solvent, the arrangement is made in the form of a second guide element.

The first Executive direction according to the second aspect oriented preferably perpendicular to the second Executive direction. Using the first Executive direction Executive item capacity for extractable substances immersed in the solution, and using a second Executive direction set time interval. Thus, through the PE pendicular the location of the two actuating directions of the two different functions, i.e. lowering capacity for extractable substances and to set the time interval, can optimally relative to each other to be supported. Further, due to this, it becomes possible actuation by a single element.

In some embodiments, valid also other locations both Executive directions relative to each other. Both the Executive direction can, for example, to form an angle, which is significantly greater than or less than 90, in particular both the Executive direction can be even counter-parallel. Finally, it would be acceptable even unstable in the Executive area of the angle between the Executive directions. For example, the first Executive direction could match the direction of lowering the capacity for extractable substances, and the second actuating direction could be set via a valve or lever, which is relative to the direction of penetration, for example, an angle of 45. Due to this, it would be possible ergonomic control device, in particular, if the device according to the second aspect is maintained, for example, a user standing on the height of the table. Further, it would also be acceptable rotated relative to the direction of penetration, Executive linear e.g. the pressure, which, for example, could be made in the form of a push button which is located above the handle containers of solvent for thumb control. Finally, the Executive direction could be even spiral or similar.

Preferably, the first Executive direction according to the second aspect made essentially rectilinearly, in particular, vertically rectilinearly, and the second actuating direction is made essentially in the form of rotation, in particular in the form of a rotation around the vertical axis. Typically, lowering the capacity for extractable substances should spend more effort to install than the time interval, in consequence of which it is reasonable straightforward first Executive direction. For setting the time interval is preferred rotational movement, as known to such actuation of the timer by the user, for example, a typical hourglass. These both Executive direction should simply be separated from each other, which, on the other hand, it is easy servicing nozzle according to the second aspect. Finally, the timer needs small amounts of energy, causing accumulated in the second part of the battery according to the second aspect of energy can be produced without problems pose the STV less strong movement for a short stretch.

In some embodiments, the Executive direction can also be selected differently, in particular, as mentioned above. The first Executive direction could also be defined as the rotation of the lever arm, for example, in the vertical plane, while the second Executive direction defined by the rotation of the same arm in the horizontal plane.

The preferred way speaker element, the first element of the second aspect is connected with the actuating element of the second aspect. Due to this, the number of moving parts and complexity of devices are supported insignificant. In another embodiment, the actuating element can simultaneously assume the function of capacity for extractable substances (or Vice versa), resulting in the protruding element is indirectly connected to the actuating element.

On the other hand, the protruding element is also directly related to the capacity for extractable substances. Finally, also a valid location of the speaker element on another, separate element that is not connected with any Executive member or with capacity for extractable substances.

Preferably, the timer of the second aspect includes mechanical brake. It can be based on known principles, for example the EP, mechanical time the brake mechanism, a centrifugal brake mechanism, a conventional brake device, the damping device or similar device.

The brake mechanism can also be electric. For example, this could be used as a generator brake. The time interval could also be installed through a resistor. Next, you could also charge a capacitor or battery, and this way, the accumulated energy at the expiration of the time interval could be provided for acoustic or optical signal. For this purpose, an electrical conductor or constructive parts would have to be well sealed (encapsulated) from water penetration, so that the device, respectively, the nozzle can be safely cleaned. But due to this design would be difficult and more expensive.

In one preferred embodiment of the second aspect of the mechanical brake stops the discharge of the second part of the energy accumulator, in particular, unloading the second spring. The brake mechanism allows controlled discharge of the second spring, respectively, of a spring timer, and thereby the expiration of the preset time interval. In one preferred embodiment, the mechanical endurance of tormosov the mechanism is defined as follows, what is the maximum time interval corresponds approximately to twice setnewtablename time interval, thereby, on the one hand, remains guaranteed accuracy of setting of the time interval, but, nevertheless, possible to take into account the needs of the user relative to the preferred time interval. For example, it is possible that certain extraction drinks should the welding time in a quarter of an hour, while others are prepared already in the minute range. In this case, the preset time interval depending on the implementation can be set continuously or discretely. On the one hand, this can be achieved by selecting the torsion spring of the second aspect, respectively, of a spring timer, and on the other hand, by selecting and/or installation of the brake mechanism.

In some embodiments, for the above-described mechanical brake mechanism of the second aspect, by him or by another mechanical brake mechanism may also be hindered by the discharge of the first part of the energy accumulator, in particular, the unloading of the first spring. Due to this can be achieved by a "soft" lifting capacity for extractable substances. In addition, conventional mechanical tensioner as PR is simple hourglass, may include a second spring, respectively, spring timer, and a mechanical brake mechanism.

Preferably, the mechanical brake mechanism of the second aspect of the invention includes made with the possibility of rotation located motionless relative to the capacity of the solvent during preparation of the extraction of the beverage element with a braking device, which interacts with a fixed relative capacity for extractable substances area and thus slows down the discharge of the second spring. Made with the possibility of rotation of the element is made preferably in the form of fixed on supports, disc-shaped element and is stationary relative to the capacity of the solvent.

In this case, the brake device can be performed in a known manner. For example, a support made with the possibility of rotation of the element may be loaded by sliding friction so that the rotation is performed in the rotating element is inhibited. Due to this it is especially simple and economical brake mechanism. Further, the brake can also be carried out in the form of brake mechanism, similar to the brake mechanism of the clock, or made in the form of a centrifugal brake.

The brake mechanism of the second aspect, in some embodiments, simple with what you learn may be made in the form of a friction brake with a brake Shoe, which interacts with the surface capacity for extractable substances. This results in a simple and economical construction. Finally, it can also be used with pneumatic or hydraulic damping, similar to the spring damping of the car, and the damping directly interacts with a spring.

The preferred image of a mechanical brake mechanism according to the second aspect includes a gear wheel and the brake device. The actuating element has to do this in the stationary region of the recess or profiling, in particular in the form of a profile rack. Toothed wheel, the brake device and the notches are now with interaction so that they inhibit the movement of the element in the second actuating direction, in particular, unloading the second spring. With such a design is achieved by the reliable power transmission and thereby a precise setting of the time interval. When this braking can be performed through the silicon support axis gear.

In some embodiments, a mechanical brake mechanism of the second aspect includes a disc-shaped element with the district in contact with a fixed edge region with a relatively high coefficient of t is possible. Due to this, in particular, when used with higher stiffness coefficient of the second spring, prevents the sliding of the disc-shaped element in a fixed area, which could lead to falsification of the specified time interval. High friction clutch between the circumferential edge and the fixed region may be performed by selecting suitable materials, such as rubber for the district territory and the polymer material for the stationary region. Thereby is achieved that the stationary region need not specifically be processed because the rubber has a high friction clutch with most polymeric materials and metals, respectively, alloys.

The preset time interval of the second aspect preferably set sweep deflection element in the second actuating direction. Due to this it can clearly differ lowering capacity for extractable substances and to set the time interval. Of course, in principle it is also possible to set the time interval by another, separate element.

The preferred image of a mechanical brake mechanism of the second aspect is arranged to bypass, in particular, off by another use is sustained fashion item. This is an advantage, particularly when it was installed a very large time interval or for any other reason must be prematurely interrupted preparation for extraction of the beverage. In this case, using a different actuating element of the brake mechanism is shunted, causing unloaded the second spring, respectively, the spring of the timer and the preset time interval goes to zero. Preferably, this is accomplished due to the fact that the interaction is made with the rotating member and the brake mechanism is arranged to interrupt. For this purpose, a mechanical brake mechanism by means of another element is mounted for displacement axially against the spring force, on the axis so that in the absence of actuation of the other element gear interacts with the profile of the toothed rack, which remains stalled unloading the second spring, respectively, of a spring timer, and when the actuation of the other element gear does not interact with the profile of the rack, thereby unloading the second spring, respectively, of a spring timer, no longer inhibited by the brake mechanism. In the second aspect of the invention is to moldstat by what other gear as a bridge provided between the slots and located with the possibility of axial movement of the toothed wheel. In this embodiment, in the actuation of another element located with the possibility of axial movement of the toothed wheel is disconnected with another toothed wheel, thereby shunted braking action, which acts exclusively on the set with the ability to move gear. It can also be carried out by the interruption of the contact between the rotatably element and the profile of the rack. For this purpose, the actuating element can have, for example, a groove perpendicular to the axis of rotation is made with the possibility of rotation of the element, and existing above or below the recess region, so that the actuation of another element braked gear could be moved axially in the region of the groove and thereby do not co-operate more with the profile of the rack.

In one embodiment, from continuemos mechanical brake mechanism also can be waived, in particular, if the second spring may again be discharged manually without risk of damage.

Preferably, when lifting capacity for extractable substances Vtorov the aspect loaded spring element, which when you load or unload hits caller the body and thus gives a signal. Preferably, the device has for this purpose a bell, which in the cooking time is motionless relative to the reference plate, and a spring element for striking the bell, which is stationary relative to the capacity of extractable substances. For the sake of simplicity spring element is designed in one piece with the guide. The protruding element describes during lifting capacity for extractable substances trajectory, which is springy element. Now to lift the tank for extractable substances protruding element simultaneously directed through the guide, whereupon the protruding element is in contact with the spring element, which spring element strikes the bell. By spring run-lifting capacity of the extracted substances is not interrupted. This has the advantage that the signal can take on the energy of the first, in particular, the larger part of the energy accumulator.

Further, also in the same field can mechanically get color or may indicate the remaining time interval by means of an indicator similar to that of Libra. The bell can also be located with the possibility of hitting him is eposredstvenno the above-mentioned element, and in this case the bell is preferably spring is held. Further, under certain circumstances it is also possible to completely abandon signaling.

Preferably capacity for extractable substances according to the second aspect Rethimno held on the lifting device. This achieves easy filling and emptying containers for extractable substances, but also allows its ergonomic cleaning. Capacity for extractable substances of the second aspect may have a locking device that stoparic it in the axial direction in the sense that when it is lowered it does not rise from the holder, but the user, in spite of this, you can easily remove it from the holder. This can be achieved, for example, by means of a bayonet catch, conical execution capacity for extractable substances and correspondingly formed receiving element which may be achieved by connection to the power circuit of the clamping bolt or the like. Next, using detachable retention capacity for extractable substances there is a possibility to use the disposable inserts. The preferred way capacity for extractable substances are designed to insert into the retaining device.

In some the older versions capacity for extractable substances rigidly connected with the holding device, therefore the design can further be simplified. But this would have the disadvantage that the capacity for extractable substances could be replaced separately. Further, the holding device connected with the capacity for extractable substances also can Rethimno be integrated into the device.

Capacity for extractable substances according to the second aspect preferably formed essentially in the form of a cylinder, which at least at its bottom has a lot of holes (perforations), in particular, a sieve or a network, which in the lowered state allow the flow of solvent. This also may be provided a filter insert, so that is insoluble in the solvent particles extracted substances upon expiration of the time interval does not remain in the solvent, respectively, in the capacity of the solvent. For this purpose, expediently in the upper limit of allowable particle size and lower bounds volumetric flow streamlines through these holes (perforations). For this size with hole surface, the density of holes (number of holes per unit surface area), as well as the size of the holes are coordinated with each other. Also it is possible to provide different capacity for extractable substances, is the quiet adjusted to the respective extracted substance. In particular, the capacity for extractable substances can be made of two parts, including made in the form of a pipe holding part and having essentially the form of a closed one side of the hollow cylinder mesh part, which is made with the possibility of putting in the retaining portion, resulting in a mesh part can be interchangeable. For example, the capacity for extractable substances, respectively, only a mesh part could be made suitable for the reception of a commercially available coffee filter, and the other for reception of tea. This capacity for extractable substances also have a few made for this large surface holes. Capacity for extractable substances can also be designed to receive a filter.

Alternative or additionally, the device is a check valve for exceptional ease of inlet solvent capacity for extractable substances would also be preferable as a valid option exercise capacity for extractable substances, and this could be used either commercially available ball check valves, either spring loaded force, United articulated in the internal space with capacity for extractable substances valve. Also assessessment to provide capacity for extractable substances from passing through the Assembly slots or grooves. The slots could be oriented horizontally, axially or spirally. Further, the slots may be oriented the same way, as it takes place in a vegetable grater, i.e. they can be inclined to the flow direction, which is inclined to the axis of rotation capacity for extractable substances. Because of this, when the flow into and flow of the solvent is its twist (twisting), resulting rapid removal of dissolved extract from the surface of extractable substances and thereby efficient extraction. Such turbulence can also be created or maintained by a separate thread (breakwater) in the inner space of the vessel for extractable substances. This, in turn, would have the disadvantage that the cleaning of this capacity would be hindered. Capacity for extractable substances can also be performed pyramid, truncated pyramid or the like.

Preferably the actuating element of the second aspect includes a cylindrical side wall for the reception capacity for extraction of the substance. Cylindrical side wall having an internal diameter external diameter capacity for extractable substances. Further, the capacity for extractable substances preferred about what atom has a folded edge, which fixes the position of the vessel in the axial direction and simultaneously facilitates the extraction capacity for extractable substances, the latter can further be facilitated by advanced radially protruding from the bent edge over the cylindrical side wall parts. The preferred way capacity for extractable substances of the second aspect is charged with preventing from turning. This can be done, for example, by selecting the material or through profiling - in particular, through the axially executed grooves - in contact surfaces.

The preferred way capacity for extractable substances of the second aspect consists of two parts, namely a cylindrical side wall with a folded edge of the cylindrical vessel, which is on the outer side, preferably the upper edge, has a few spring pieces, which are preferably symmetrically arranged around the perimeter of the vessel. For this purpose, the cylindrical side wall has on the inner wall a few, but preferably two, of the district zheloboobraznogo and/or the profiled receiving element for spring parts. Thereby is achieved that the cylindrical vessel is charged with the rearrangement of the height of the cylindrical side wall. If the cylindrical container is pushed into the cylindrical side wall, accordingly, pulls out, the springy part of the lock, resulting in a cylindrical vessel axially fixed so that it is only at high, but acceptable for the average user effort can be extracted from the lock and may axially be displaced again to snap into place in a different height position. Through this axial shifting of the execution of the cylindrical vessel, the device can be used for various, in particular, small (for example, approximately 0.7 l) and large (for example, approximately 1.2 l) volume of solvent. Thus in the case of a small volume of solvent capacity for extractable substances telescopically extended, and at high volume - contracted. Because of this, when the appropriate amount is guaranteed that, when lowered capacity for extractable substances it also really immersed in the solvent, respectively, while lifting capacity for extractable substances it is not loaded or at most slightly immersed in the solvent.

While the cylindrical side wall of the second aspect, the preferred way is made double-walled, so that the first spring may be taken between the walls. Due to this it is achieved that the spring during preparation, extraction drink not seen is on and thus can also decrease the risks of damage.

Instead of the cylindrical side wall is also valid for other reception items. So, for example, could be provided by three or more fingers for retention.

The preferred way of the cylindrical side wall of the second aspect interacts with the first and second spring. Due to this, the capacity for extractable substances can regardless of the position of element to be deleted, respectively, used or replaced.

In some embodiments, in particular, in the embodiment, is rigidly connected with a lifting device with a capacity for extractable substances, first and second springs can be directly rigidly connected with capacity for extractable substances. However, it is also allowable indirect interaction of the spring and a cylindrical side wall or capacity for extractable substances.

The invention also includes the teapot, which has a capacity for solvent, and the nozzle according to the first or second aspect of the invention. The capacity of the solvent is preferably the same maker and thus rather classic circular form, as it simplifies its clearance. On the transition from the body of the kettle to the spout may be located a filter or sieve to retain unwanted remnants of the former is rationalo substances. This, in particular, has an advantage when the capacity for extractable substances made rather crudely filter, which in turn requires flow through the extraction agent.

The capacity of the solvent is preferably formed of heat resistant polymeric material or glass. Suited for this many polymeric materials, in particular from the class of thermosetting polymers. For this non-exceptionally could mention PF (phenol-formaldehyde resin), MF/MP (melamine/melamine-phenolic resin), UF (urea resins), UP (unsaturated polyester resin), EP (epoxy resin), Si (siloxane resin), DAP/DIAL (diallylphthalate resin/digitallifestyle resin). The polymeric material for containers for solvent has the advantage that the production is cost effective and simple. Further, due to this the weight of the device is kept small.

In some embodiments, this can also be applied to other materials, for example, metal alloys (e.g. steel, chromium steel, glaze), in particular, if the solvent should be directly in the tank for the solvent to warm up on the heating plate. Also a valid use of porcelain and ceramics.

Capacity for solvent can also have a classic shape, in particular, it may be, is for example, modern (modernistic) or an unusual shape, which fits perfectly with other items. When this option implementation capacity of the solvent with tubular spout is also acceptable. This achieves that concentrated presents color and aromatic substances retained in the lower part of the kettle as initially filled and possibly floating residues extractable substances. In one other embodiment, the spout may be attached also at the top, in the region of the edges of a capacity for solvent to keep the settled when pouring the remains.

Further, according to the second aspect of the invention also created a way for managed at the time of preparation of the extraction of the beverage, wherein the actuating element is provided in two different Executive directions, and through the first Executive direction capacity for extractable substances is lowered into the inner space of the vessel for solvent and charging the first part of the energy accumulator, and the second Executive direction specified time interval and activates the timer, and charging the second part of the energy accumulator. Fundamentally, the Executive member may, either sequentially or in parallel to operate in both will perform the selected directions. The sequential actuation element can be chosen freely sequence of the Executive directions.

A preferred manner, the method according to the second aspect passes successively with the following steps. By means of the actuating element in the second Executive direction specified time interval and activates the timer, and charging the second part of the energy accumulator. By means of the actuating element in the first Executive direction capacity for extractable substances is lowered into the inner space of the vessel for solvent and charging the first part of the energy accumulator. The actuating element is moved through the second discharge of the battery energy within a predefined time interval against the second Executive direction. The actuating element is moved through the first discharge of the battery energy after a predefined time interval against the first Executive direction and raises the capacity of the solvent from the lowered state.

While the first and second aspect show essentially two separate paths for the solutions of the corresponding image is the shadow of tasks, the specialist should be immediately clear that the various elements can preferably be exchanged between the two aspects, provided that they are structurally not contradict each other. In particular, for example, a cylindrical side wall of the second aspect can replace the bushing to the first aspect. Similarly, fastening capacity for extractable substances on the lifting device or execution capacity for extractable substances can be exchanged between the implementation of both aspects without significant changes.

From the subsequent detailed description and the totality of the claims follow other preferred embodiments of and combinations of features of the invention.

In principle, identical parts in the figures are denoted by the same reference position.

In the following paragraphs on the basis of figure 1-9 describes the first version of the implementation according to the first aspect of the invention.

Figure 1 shows a side view of the first variant of implementation of the relevant invention device 1A with a nozzle 2A on the vessel 3 to dissolve the I, with a capacity of 200 for extractable substances is in a lowered state. The nozzle 2A is made with the possibility of split, in particular flush, connection with capacity for 3 solvent. In some embodiments, the implementation also provides swivel nozzles 2A with a capacity of 3 to solvent, which sometimes can also be split.

Attachment 2A as the major component parts includes a main portion 100, which is placed on the capacity for 3 solvent and a capacity of 200 for extractable substances, and from it figure 1 shows the flange 221, which lays on the main part. Further, the nozzle 2A includes a timer 300, which as a cover mounted on the container 200 for extractable substances and adjacent to the flange 301 to the flange 221 capacity 200 for extractable substances. In addition, the timer 300 includes a rotary switch 302 for setting the time interval.

Figure 2 shows in exploded view from the side view device 1A according to figure 1. Essentially, this view shows the components that are used in the application of the device. First of all, capacity 200 for the extracted substance is extracted substance, for example, tea, and then be entered in the main part 100. Capacity 200 for extragear is imago substances is closed by the timer 300. Then, by turning the rotary switch 302 timer 300 is set to a time interval. Finally, the switch 302 a capacity of 200 for extractable substances is introduced into the inner space of the vessel 3 to the solvent. After a specified time interval capacity 200 for extractable substances jumps back so that it no longer acts, or only partially protrudes into the inner space of the vessel 3 to the solvent.

Next, figure 2 shows that the timer 300 is essentially cylindrical basic shape. Rotary switch 302 is set to rotate coaxially this basic form. Further, the timer 300 includes a triggering element 303, which is made in the form of two pins that are located opposite each other relative to the axis. The triggering element 303 relative to the rotary switch 302 is offset axially downward and is mounted coaxially with the possibility of rotation. The triggering element 303 stands for the diameter of the timer 300, but not for its flange 301, and for the time interval describes an arc of a circular sector. The triggering element 303 is connected directly with the movement of the rotary switch 302, this means that when you set the time interval with the rotary switch 302 triggering element 303 rotates the I to the left of that switch around its axis of rotation.

In addition, below the flange 301 of the timer 300 is visible protrusion 304, which passes axially to the flange 301. The second protrusion 304 is located on the back of the timer 300 (not visible).

Capacity 200 for extractable substances in this embodiment, the implementation consists of two parts and includes a mesh part 210 and the holding part 220. Mesh part 210 has essentially the form of a closed one side of a hollow cylinder with a circular base area. At the bottom of the mesh part 210 are holes that allow the passage of solvent (not shown). Holding part 220 is made essentially in the form of an open two sides of a hollow cylinder with a circular main surface and has an inner diameter that matches the outer diameter of the mesh part 210. Thus, a mesh part 210 may telescopically be entered in a holding part 220, and in different axial positions recorded (not shown) by means of the fixing protrusions and corresponding recesses, which can even be performed by the district. Thus, the depth of immersion of the vessel 200 for extractable substances in a container 3 for solvent can be adjusted to the level of the solvent.

The retaining portion 220 in the upper region of the inner wall has two opposite recesses 223, in which when inserted the timer 300 may enter the protrusions 304 and thus freeze the rotation of the timer 300 relative to the holding part 220. Further, the retaining portion 220 in the upper pane has a flange 221 that protrudes radially outward. Then, in the upper region of the holding part 220 has two opposite openings, passing along the arc of a circular sector of approximately 90, which are L-shaped surface in cross section. From figure 2 it is seen that the aperture 222 covers only the inner part of the flange 221. In this area the diameter of the holding part 220 corresponds to the diameter of the triggering element 303 timer 300, respectively, the maximum distance between the two pins of the triggering element 303. The timer 300 may be mounted on the holding part 220 so that the triggering element 303 at any fixed time interval may be sent to the respective openings 222, provided that the timer 300 is placed so that its protrusions 304 installed in the notches 223 holding part 220. For the user this presents no special difficulties, as it can turn the timer back and forth in the area of approximately +/-45, until it snaps into place in the retaining portion 220. On the outer wall, under the flange 221 and the opposite of the grooves, the retaining part has two protrusions 224.

Finally, figure 2 still partially visible sleeve 400, which presents the image is kept in the main body 100 through not visible here, the block is an enabling device.

Figure 3 shows performed essentially as open from two sides of a circular cylinder sleeve 400, which includes an outer wall 401 and the inner wall 402, which define an intermediate space and is connected to the upper edge region. Inner wall 402 is down on the outer wall 401. In addition, the sleeve 400 inside the inner wall 402 is adjacent to the upper edge of the two opposite recesses 404, which includes protrusions 224 of the retaining portion 220 of the container 200 for extractable substances and thus can hold it from turning. If you now have a capacity of 200 for extractable substance is inserted into the sleeve 400, the openings 403 sleeve communicate with the openings 222 of the holding part 220, and the flange 221 of the holding part 220 is adjacent to the upper edge of the sleeve 400. As the capacity of 200 for extractable substances, the sleeve also has openings 403, which have L-shaped cross-section. Here also, the top edge is not completely interrupted. When planted the timer 300 triggering element 303 protrudes through the openings 222 and 403, in particular, radially outside the inner wall 402, but not to the outer wall 401. Thus, the radially outer ends of the triggering element 303 during the time interval are moved into the intermediate space between the inner wall 402 and the outer wall 401 of the sleeve 400.

Further, the sleeve 400 in the lower edge region of the outer wall 401 formed two displaced radially outward relative to the outer wall 401 and protruding axially downward of the pin 406. These pins are arranged offset relative to the slider 405 90in approximately the same plane and perpendicular to the longitudinal axis of the sleeve 400.

Finally, the sleeve 400 in the lower edge region of the outer wall 401 formed with two protruding radially outward relative to the outer wall 401 locking hook 407, which is oriented essentially tangentially to the sleeve 400. When viewed from above, the locking hooks 407 are under the openings 403, in particular, relative to the direction of movement clockwise in the first, respectively, the initial part of the corresponding aperture 403.

Figure 4 shows the base plate 500, which includes to iceway plate 510 with opening 511, chamber connected with the aperture 511, axially located and protruding up guide sleeve 520 and made L-shaped in cross-section, made around the outer circumferential edge 510 flange 530. Guide bushing 520 is made essentially in the form of pipe and shall be of such dimensions that the sleeve 400 can sit down on the guide sleeve 520 so that she was between the outer wall 401 and the inner wall 402. In the upper area of the guide sleeve 520 has within its walls, two opposite, obecause approximately 90 notches 521, respectively, the thinning of the material, which - when viewed from above begin in the direction of clockwise with interrupt 522. The notches 521, respectively, thinning of the material, speak to the top edge of the guide sleeve 520 and have a shape elongated along the circumference of the guide sleeve 520 forms, and interrupt 522 are almost square in shape.

The plate 510 of the support plate 500 has two, opposite relative to the guide sleeve 520 and the axially oriented retaining sleeve 512 for guide rods 513 (figs.4 not shown). Between the retaining sleeve 512 and the outer wall of the guide sleeve 520 with the latter respectively located axially oriented guide 513 throughout high is the same. If planted sleeve 400 guide bar, which is axially formed on the inner side of the outer wall 401 is moved in the above-mentioned guide 513, whereupon the sleeve 400 may move relative to the guide sleeve 520 to prevent from turning. Two guides 514 for spring are located on the plate 510 with an offset relative to the retaining sleeve 90 and are respectively axially oriented hole.

Guides 408 on the outer side of the inner wall 402 of the sleeve 400 serve to guide the sleeve 400 on the guide sleeve 520 with low friction losses, so this reduces the contact surface. Thus, the direction becomes generally reliable, in particular with respect to the action of dirt.

The first side flange 513 530, speaking axially upward, is connected with the plate 510 and the second side 532 on the upper end of the first side 531 protrudes radially outward. The lower side of the second side 532 forms a bearing surface for bearing on the capacity of 3 to solvent. The upper side of the second side 532 has a number of holding elements 533 for mounting hemispherical covering the bowl 600 (see Fig 1,2 or 9). For easier reading of the figures, the reference positions respectively provided with only two derives the x element 533.

Figure 5 shows the base plate 500 according to figure 4 with fitted sleeve 400 according to figure 3. Additionally, the sleeve 400 is depicted only triggering element 303 timer 300, to provide a more meaningful representation of the principle of operation of the device. For a better overview capacity 200 for extractable substances are also not shown. In addition to the previous 1-4 this view shows essentially the decompressed helical spring 409 compression, which is located around the pin 406 of the sleeve 400. The lower end of the spring included in the guide 514 for the spring and therefore travels guide 514 for the spring and pin 406. The same location is also on the reverse side. Further, visible axially oriented and acting up rod 515, which is rigidly mounted in the retaining sleeve 512. The sleeve 400 is linearly goes through the slider 405 and rod 515. This is the second time on the reverse side.

Next, executed in the form of a lever actuating element 523 is connected with a locking hook 524, which is rotatable about a radial axis on the guide sleeve 520. The locking hook 524 is located essentially horizontally above, but near the specified axis and were distanced radially outward from the Executive element is and 523. The Executive element 523 and the locking hook by means not shown twisted Flexural spring loaded return force and held in a substantially axial position. The Executive element 523 is their top end before terminating 522 and additionally has a protrusion that protrudes through the interrupt 522. The ledge serves as a contact element, through which can operate the triggering element 303 element 523.

The triggering element 303 is coaxial with the sleeve 400 and includes essentially coaxial circular ring, which is connected with the established center with the possibility of rotation of the beam, and a beam with two sides stands for the o-ring and thus forms the contact elements protrusions element 523.

In figure 5, the sleeve 400 is not blocked, and raised. The time interval is not set, respectively, has already expired. On this view it is seen that twisted Flexural spring is stressed and the next moment the Executive element 523 together with retaining hook 524 will bounce back in the axial position.

To activate the device, now the timer 300 is set to a time interval, resulting in the triggering element 300 depending on the time interval in larger or smaller is her degree turns - when viewed from above in the direction of clockwise. Then, the sleeve 400 nadavlivaya down, as a result of this coil spring 409 compression is compressed, and the locking hook 524 element 523 is engaged with a locking hook 407 sleeve 400 and thereby prevents premature Bouncing back. During the time interval now triggering element 303 is rotated back against the direction of movement clockwise until until the outer end of the triggering element 303 will not come into contact with the guide element. This state is shown in Fig.6.

6 shows the structural elements already shown in figure 5. In contrast to figure 5, the sleeve 400 is locked in the lowest position by the locking hook 407 sleeve and the locking hook 524 of the guide sleeve 520. The Executive element 523 is held by a twisted Flexural springs in axial orientation, coil spring 409 compression is in a compressed state. The triggering element 303 is already in the corresponding current elapsed time interval position and the next moment the Executive element 523 is powered so that it is if to look from above - will turn against the direction of movement clockwise and release the locking hook 524 of the locking hook liners is I. This entails that the sleeve returns through the efforts of the coil spring 409 compression moves up, resulting in restored condition according to figure 5.

7 shows essentially the same as figure 5, with the sleeve 400 is not represented. On the basis of the triggering element 303 can be seen that this view set the maximum time interval, capacity 200 for extractable substances but (yet) down-directed. The triggering element 303 is rotated, namely in the direction of clockwise, until it stops opening 222 capacity 200 for extractable substances.

Fig, in turn, essentially corresponds to 6, and the sleeve 400 is not represented. In the shown state, the time interval is expired. The triggering element 303 is already in contact with the actuating element 523, however, the locking device has not yet been released, as the Executive element 523 is focused yet vertically.

Fig.9 shows a vertical section along the longitudinal axis through the device 1A according to figure 1. Capacity 200 for extractable substances is in the brewing position, i.e. the inserted down into the inner space of the vessel 3 to the solvent.

This view is clearly visible telescopic design of the sleeve 200 for extractable substances. Mesh frequent the 210 on the periphery, in this embodiment, on two levels, has elastic protrusions 211, which protrude radially outward. At appropriate places holding part 220 has recesses 225, which may take the protrusions 211. Thus, the mesh portion 210 can reach down from the holding part up until the upper protrusions 211 will not drop into the bottom of the recess 225.

In the following paragraphs on the basis of Fig. 10-14 describes the second version of the implementation according to the second aspect of the invention.

Figure 10 shows a side view of the device 1b according to the second aspect of the invention the activated timer. Further, visible capacity for 3 solvent and a suitable nozzle 2b in the second embodiment. Attachment 2b Rethimno, in particular with geometric circuit, connected to the tank 3 to the solvent. In some embodiments provided also swivel nozzle 2b with a capacity of 3 to solvent, which may also sometimes be made detachable.

Capacity for 3 solvent in this embodiment, consists of a glass or polymer material, has a capacity of, for example, approximately two liters and has two marks 3A and 3b, with the lowest mark 3A is at the level of 0.7 l, and the highest mark 3b - 1,2 L. However, the capacity certainly could have other shapes and the other is capacity and can be made of other materials.

On fig.10b, which, in turn, shows a side view of the device according to the second aspect, but from the opposite side and is not activated by the timer in the upper region of the nozzle 2b visible rim provided with a rim of the cylindrical side wall 4b of the container 4 for extractable substances, and a lid 5. Finally, you can see the second actuating element 14b and double-walled side wall 13, which below will be examined in more detail. In this case, the actuating element 14a is composed of the cover 5, provided with a rim of the cylindrical side wall 4b and double-walled side wall 13.

On figa presents a section along the symmetry axis of the vessel 3 for solvent through the device 1b according to the second aspect, when activated timer.

Double-walled side wall 13 is closed with one hand and takes between both walls 13A, 13b are made of spring steel coil spring 6, which in the relaxed state is on the open side of the double-walled side wall 13 (see fig.11b), and in the stress state can be fully accepted it.

The bottom region 17 includes a single cylindrical side wall 19, which surrounds the opening 17A in the bottom region 17, which essentially corresponds to the cross-sectional area of the vessel 4 for extractable substances. Single-walled Qili the shape of the side wall 19 has an internal diameter in the region of the outer diameter of the inner side wall 13b double-walled side wall 13, so double-walled side wall 13 is arranged to turn the top over single-walled cylindrical side wall 19. Coil spring 6 has an outer diameter to the inner diameter of the outer side wall 13A such that the double-walled side wall 13 is also made with the possibility of turning (slipped on easily) on top of the coil spring 6. The inner diameter of the coil spring 6 is located in the region of the outer diameter of single-walled side wall 19. Further, both side walls 13A, 13b double-walled side wall 13 distanced from each other so that the double-walled side wall 13 is made with possibility of simultaneous inversion on top of the single-walled cylindrical side wall 19 and the coil spring 6. In this arrangement, it is now possible voltage/loading of the coil spring 6 due to the fact that the double-walled side wall 13 is pressed (nadavlivaya in direction) to the base region 17. On figa coil spring 6 is visible in the fully compressed state of the device 1b, and fig.11b is in an unstressed condition. Alternatively, the location of single-walled cylindrical side wall 19 and the coil spring 6 can also be replaced so that the coil spring 6 is attached to the inner wall single wall cylindrical side wall 19.

Capacity 4 to the extracted washes the VA performed, essentially cylindrical and one side is open and has a cross sectional area in the range of the size of the hole 17A of the bottom region 17. In this case, the rim is equipped with a rim of the cylindrical side wall 4b is in the area of the openings of the containers 4 for extractable substances and can be closed by a cover 5 by means of geometrical and/or power circuit. 4 capacity for extractable substances on the bottom and/or side wall in the bottom has many holes that figa and 11b occupy a large area and is suitable for receiving a replaceable filter element. But they can be done differently, in particular, smaller, or only in the bottom region of the vessel 4 for extractable substances. The outer diameter of the vessel 4 for extractable substances is the inner diameter double-walled side wall 13 so that the capacity of 4 for extractable substances can easily be in the double-walled side wall 13 to the contour provided with a rim of the cylindrical side wall 4b which may be clenching, respectively, the tension coil spring by means of a cover 5, respectively, through the vessel 4 for extractable substances. Consequently, charging the first part of the energy accumulator, which after a time interval the raise which has a capacity of 4 for extractable substances.

4 capacity for extractable substances in the present embodiment, is made of two parts and includes a cylindrical vessel 4A and provided with a rim of the cylindrical side wall 4b. 4 capacity for extractable substances can be made whole (one-part). A cylindrical vessel 4A figa and 11b has holes and is made for the reception of the sieve or filter, and a sieve or filter can also be directly integrated in a cylindrical vessel 4A. Equipped with a rim of the cylindrical side wall 4b has on the inner wall of the two districts, made in the form of grooves receiving element, and a cylindrical vessel 4A has a corresponding protruding radially outward springing of the parts when the axial movement of the cylindrical vessel 4A is equipped with a rim of the cylindrical side wall 4b drop in made in the form of grooves receiving elements. Spring elements in the form of grooves receiving elements are matched to each other so that by axially applied force saskuchilsia springy elements can easily go from being committed in order to be able again to take another made in the form of a groove receiving element.

Next, figa and 11b visible torsion spring 7 is executed again from spring steel. The use is consistent here, the torsion spring 7 has the form of a coil spring. She is dismissive low coefficient of stiffness of the spring (elastic modulus) in the axial direction, but not in the tangential direction. Thus, figa and 11b are not visible, they are tense or not. The torsion spring 7, the first end connected to a bottom region 17, and the opposite end to the double-walled side wall 13 so that when the rotation of the double-walled side wall 13 of the torsion spring 7 strains, respectively, is discharged. To do this, double-walled side wall 13 has a mount (holder) 13d torsion springs (not visible). Due to this, charging the second part of the battery energy that powers the timer.

On fig.11b unlike figa incision is depicted along the symmetry axis of the vessel 3 for solvent through the device 1b according to the second aspect when non-activated timer, as well as from the opposite side. In particular, fig.11b visible torsion spring 7 and a raised lifting device capacity 4 for extractable substances. The torsion spring 7 on figa is essentially unloaded, which in turn may account for its axial deformation, and based on the fact that elevated tank 4 for extractable substances.

Next, fig.11b visible second actuating element 14b, which will be discussed in detail when explaining the following figure.

On Fig depicted is a schematic representation of a perspective view of double-walled side wall 13, the second element 14b, link 12, the bell 16 and the torsion spring 7 in the assembled state according to the second aspect when activated the timer.

Next, on the basis of Fig explains the timer according to the second aspect. Double-walled side wall 13 has a protruding profile 13C in the form of a toothed rack, which is held axially in the region of the outer surface of the outer side wall 13A, and this area is oriented in axial direction of the height h. Alternatively, the profile may be made in the form of grooves, respectively, of the recesses. First gear 9a of their teeth engages with the profile of 13C in the form of a toothed rack, and the axis of the first gear 9a is parallel to the longitudinal axis of the double-walled side wall 13 and through the base region 17 and the cover 15 mounted for rotation (not visible here). The first gear wheel 9 has a height that is the sum of the maximum lifting height capacity 4 for extractable substances and height h. Second gear 9b, which in relation to the first toothed wheel 9a has a small height, interacts with the first toothed wheel 9 and thus has an axis of rotation parallel to the axis of rotation of the first gears 9a, and is installed with the possibility of rotation by a cover 15 (here not widn is). The second actuating element 14b includes slowed down a gear wheel 10, which communicates with the second gear 9b. Slow gear wheel 10 is installed with the possibility of axial displacement against the action of spring force, so that when it is brought into action slowed down a gear wheel 10 is axially shifted so that it no longer interacts with the toothed wheel 9b (not visible here). Thus the timer via actuation of the second actuator 14b can stop, respectively, again be set to zero. The brake device is inhibited toothed wheel 10 includes an axle which is connected with intellectual toothed wheel 10 and is installed with the retardation of the anchor sleeve, silicone or some equivalent. For this purpose, the supporting sleeve is sealed with a sealing ring with a round cross-section so that the silicone does not follow or is not oxidized. Mechanical brake mechanism is located in the nozzle 2b is thermally insulated relative to the vessel 3 for solvent so that when the fluctuation of the temperature of the solvent for a specified time interval has no effect or only a minor influence. This could also be provided with insulating material, in which the nozzle 2b screens, milling is a mini-brake mechanism (not shown).

In the lower edge area of the double-walled side wall 13 includes a mounting 13d torsion springs, which is connected with the torsion spring 7, and the other end of the torsion spring 7 shown way connected with the bottom region 17. If the torsion spring 7 is loaded by rotation of the double-walled side wall 13 (second Executive direction), then slowed down a gear wheel 10 prevents it from discharging, so that the rotation against the second Executive direction slows down. Through the angular velocity, which thereby achieves double-walled side wall 13 may be established timeline. The time interval in this case can be realized by means of the rotation angle of the double-walled side wall 13 and is essentially proportional to the rotation angle. If the set time interval you want to terminate, it is driven by the second actuating element 14b, through which disconnects the brake mechanism and the double-walled side wall 13, in essence, freely (without deceleration) back into the position in which the torsion spring 7 is unloaded.

On Fig visible wings 12, which is made essentially in the form of a segment of the cylindrical wall with the radius of the radius of the outer side wall 13A double-walled side with Enki 13. In this case, the surface and shape of the scenes 12 correspond to at least the desired profile 11 rack surface and form. The wings 12 are located essentially constant, small amount of and parallel to the outer side wall 13A double-walled side wall 13 and is connected to the bottom region 17. The wings 12 on the concave side facing the double-walled side wall 13 side in the axial direction has a groove 12A, which is at the bottom, the bottom region 17, acts ledge 12b, the inner side of the frames the connecting rod 12 (see Fig. 14). Other grooves 12d-12j are parallel to the groove 12C and at a distance from each other, have in the direction of the ledge 12b decreasing depth and over the ledge 12b. Instead of running grooves 12d-12j c decreasing depth, the wings 12 can also be positioned with a deviation to the appropriate angle to achieve the same effect.

The protruding element 8 (not visible)connected to the outer side wall 13A double-walled side wall 13, is directed through one of the slots 12C-12j 12 scenes. The protruding element 8 can be made springy. On the other hand, the connecting rod 12 can also be made springy. Springy element 12A axially in the groove 12C is connected to the connecting rod 12 and partially protrudes into the groove 12C and on the reverse side is a region of the scenes 12, being the m its springy effect radially directed. The bell 16 is held (not visible) in the cover 15 radially a short distance from the specified area so that the protruding element 8 at its directed through the groove 12C of the trajectory collides with a spring element 12A, in consequence of which the spring element 8 is loaded, and therefore, either when loading spring element 12A, or when removing loading it hits the bell 16.

Further, through the figures describe the operation of the device 1b in chronological order. On fig.11b timer (still) is not activated. The Executive element now turn anti clockwise direction so that the protruding element 8 is directed ledge 12b (figa). Through this rotation, the torsion spring 7 is loaded. Depending on the angle of rotation at the same time and essentially proportional to the rotation angle set time interval. Alternatively, the device 1b may also be performed so that the installation time interval is in the direction of clockwise. Now the capacity of 4 for extractable substances pressed down, and the coil spring 6 is loaded. During this protruding element 8, depending on the time interval that goes in the slots 12C-12j scenes, that is, during lowering of the container 4 for extractable substances it C is fixed from rotation relative to the vessel 3 to the solvent. When a sufficient lowering of the vessel 4 for extractable substances protruding element 8 is latched in the ledge 12b and thereby enters aimed at the second Executive direction region. In this position the container 4 for extractable substances is no longer secured against rotation. Then, after releasing the torsion spring 7 is unloaded attached inhibited the toothed wheel 10. During this double-walled side wall 13 projecting element 8 is directed through the ledge 12b. After a time interval, the protruding element 8 reaches the groove 12C 12 scenes and accumulated through the helical spring 6 energy rises in the axial direction, resulting in a capacity of 4 for extractable substances rises in the inner space of the vessel 3 to the solvent. Then, the protruding element 8 facing the spring element 12A and through the region of the spring element 12A strikes the bell 16, causing the user to signal that the extraction of the beverage, in particular in the time of extraction, fully cooked.

Further more explains the course of the method.

a) When the storage device 1b for managed through cooking time extraction drink 1 (hereinafter - the device 1b) capacity 4 for extractable substances for the economy and the place is in a lowered state. This includes additional or above locking device, in particular a bayonet shutter. For example, for this purpose due to the second actuator 14b braked gear wheel 10 or the double-walled side wall 13 could be possible to lock relative rotation. After the device 1b has been extracted, this lock is eliminated, resulting in the capacity for extractable substances rises from the tank to the solvent.

b) the Cover 5 is removed.

with the Capacity for 4 extractable substances by pulling over is equipped with a rim of the cylindrical side wall 4b of the double-walled side wall 13 is pulled to the desired length (depending on the desired volume of solvent).

d) Capacity 4 for extractable substances fill the extracted substance and re-insert into the double-walled side wall 13.

(e) the Extracted substance is poured solvent. The alternative, may also withdraw the nozzle 2b and the solvent is poured directly into the container 3 to the solvent.

f) the Cover 5 is placed back.

(g) By turning element 14a in the second Executive direction against the direction of the force of the torsion spring 7 set the desired time interval. When this protruding element 8 zakaki the AET in the grooves 12C-12j, for example, in a groove 12E, each of the slots 12C-12j corresponds to one time interval.

h) Now the Executive element 14a is brought into action in the first actuating direction, and the double-walled side wall 13 by his jutting element 8 is directed into the groove 12E. The depth of the groove 12E is reduced in the first Executive direction and terminates in a ledge 12b, so that when the specified actuation protruding element 8 clicks into place in the ledge 12b and thereby fixed in the opposite direction, and the coil spring 6 presses the protruding element 8 to the ledge 12b.

i) the Executive element 14a is released. Now during the time interval, which is defined by selecting the groove 12E, the Executive element 12A is rotated by the loading force of the torsion spring 7 and by means of a mechanical brake mechanism is inhibited (blocked) from moving in the second Executive direction until, until it reaches the mouth of the groove 12C.

j) At the mouth of the notch 12C direction element 14a is changed from available until now rotary motion to axial movement against the first Executive direction, whereupon the protruding element 8 is directed through the groove 12C and moves through and is cumulated in the spiral spring 6 energy. With the passage groove 12E protruding element 8 comes into contact with the spring element 12A, which in turn strikes the bell 16 and thereby provides the user with a signal that the extraction drink fully cooked.

K) For purification device 1b can now be removed the cover 5 and the capacity of 4 for extractable substances can be removed and washed. Further, the nozzle 2b can be removed from the tank 3 to the solvent, resulting in the capacity for solvent can also be washed. Then, the device 1b is reassembled, the Executive element 14a is provided in the first Executive direction and through the bayonet catch (not visible) is blocked, so that the device 1b can be provided to save space.

However, initially it may be implemented actuation in the first Executive direction and then set the time interval in the second actuating direction. The wings 12 can also be accomplished without grooves 12d-12j. Thus, the time interval could continuously (not stepped) be installed. On the other hand, thus with prior or simultaneous installation interval conversion element 14a would not be directed in the first Executive direction, resulting, in particular, pre-installed the temporal is th interval can be changed by a very low power cast element 14a in the first Executive direction.

Execution of the containers 200, 4 for the extracted substance and capacity for 3 solvent under both options the implementation essentially should not differ. In particular, they can be made identical. For example, a capacity of 200, 4 for extractable substances in both cases, the implementation has a two-part form, which can telescopically to go into each other and can be fixed in different axial positions. Also nozzles 2A, 2b can have similarities and below only approximately describes some of these similarities, which, however, applies only to the above-described variants of the implementation.

For example, in the above described embodiments implement a capacity of 200, 4 for extractable substances, respectively, is introduced from above into the nozzle 2A, 2b. Capacity 200, 4 for extractable substances, respectively, are made with top, lid 300 (timer), 5 and has a flange by which it is held in a double-walled sleeve 400, 13. Double-walled sleeve 400, 13 respectively loaded helical compression spring. Capacity 200, 4 for extractable substances together with double-walled sleeve 400, 13 translates linearly at the bottom, against the direction of action of the spring force of the helical spring 409, 6 compression in the brewing position and there locked. A blocking device which respectively includes rigidly connected to the double-walled sleeve 400, 13 item 407, 8, which in the locked position interacts through located with axial fixation relative to the nozzles 2A, 2b, item 524, 12, and so may block the unloading of the coil spring 409, 6 compression, respectively, the rise of the double-walled sleeve 400, 13, and thereby the capacity of 200, 4 for extractable substances. Attachment 2A, 2b includes turning in a time interval of coaxial capacitance 200, 4 for extractable substances element 303, 8, resulting in the expiration of the time interval locking device is released. The time interval set in the area of the cover 300, 5. Upon expiration of the time interval capacity 200, 4 for extractable substances goes linearly up through accumulated in the spiral spring 409, 6 compression energy.

The above similarities are merely exemplary and not exclusive, because in this sense, the similarities can't exactly ask. Other embodiments of also have more or fewer similarities with one of the two options for the implementation of, in particular, the invention is not limited to these two options for implementation.

The difference between these two variants of implementation of the nozzles 2A, 2b is that in the case of the first variant of implementation, the timer is integrated into the cover 300, while in Deuteronomy the m of the embodiment, the timer is integrated into the nozzle 2.
