This invention relates to juice extractors for citrus and, in particular, to electric juicers for citrus, in which the nozzle sits vertically on the shaft driven by the electric motor so that half of the citrus fruit can be pressed against the nozzle to eject from her juice. The nozzle typically has an essentially conical shape, set top upwards and provided with sokovyzhimalka ribs or other protrusions, protruding from its surface.

These juicers are well known, and the present invention particularly relates to the class of such juicers, in which the lever, swivel attached to the housing enclosing the motor and supporting the nozzle is hollow presser element intended for lowering lever for compression halves of the fruit to the nozzle and thereby facilitate the extraction of the juice. Usually a clamping element is designed as a hollow cone or a portion of a cone, and these juicers are described, for example, in FR-A-1164016 and EP-A-0226691

It is clear that the use of a lever for citrus juicers above type can create problems, as the process of pressing juice should begin with a raised arm to get the fruit could be placed over the nozzle, and, therefore, known to the present time the instruments are equipped with a spring so that so that the lever is always returned to its fully raised position after use. This means that the device generally has a height that is disproportionate to other dimensions, which is of particular disadvantage when storing the device when not in use or during transportation. It also means that if the spring effect is powerful enough reliability to fully raise the lever, it is usually enough to cause a strong reaction on the device in General, when the lever reaches the fully raised position and occurs with mechanical stopper. This reaction can be strong enough to physically move the device to the extent that allows the character of the surface, on which stands the device. Even if it does not, however, the reaction can create momentum, which is annoying for the user.

The objective of the invention is to resolve at least one of the above-mentioned problems.

According to the invention, a citrus juicer, with a vertical nozzle located on the shaft driven by the motor and configured to, upon actuation, extracting the juice from pressed to her halves of citrus, juice extractor further comprises a housing accommodating a UE is mentioned motor and supporting said nozzle, and a lever element, which is adapted for pivoting movement relative to the said casing carrying a clamping element adapted for compression of the fruit to the nozzle, whereby the said lever is raised to the position in which the mentioned clamping element is disconnected from the said nozzle and can be omitted from the aforementioned raised position for compression of the fetus to the nozzle, which has a tool that conveyed the said lever in the raised position and which has a locking means to secure the lever in a lowered position. It ensures the fixation of the lever in the lower position, in opposition to the force of development in the upper position when the device is not in use or during transportation, for example, when preparing in place for use.

The finishing tool preferably includes one or more torsion springs, although if desired, instead of or in addition can be used adaptations of coiled springs, adaptations of the leaf spring or any other suitable elastic means.

The locking means preferably includes a mechanism attached to the rack permanently attached to the housing, to which the swivel is attached to the lever. Thus, the locking means can be operated via driven by the user among the funds on the rack.

In addition, it is preferable that the securing means includes a protrusion made with the possibility of coming into engagement with a groove or recess in a component that moves with the rotation of the lever relative to the rack. Particularly preferably, the above-mentioned component directly connected with swivelling holder of the above mentioned lever on the rack.

The protrusion preferably is spring-loaded for engagement with the said groove or recess, which is driven by the user, the tool can be installed in the locking position, the lever is in its raised position and the latch is triggered automatically when a sufficient lowering of the lever.

In the preferred example, the lever is additionally equipped with damping means adapted to resist movement of the lever to its raised position, whereby the tool adjustment and damping means together provide a controlled movement of the lever to the said raised position and its smooth stop in this position.

In these embodiments of the invention, it is preferable that the damping means provides such a rotary friction damper with a housing containing a viscous material, in which the blade element is rotated by application of an external impact to the gear and the and the device, to the axis, on which the blades. Rotary friction damper is preferably set in the above-mentioned rack and pinion is driven by a rack element, paired with the lever.

In particularly preferred embodiments, the implementation of the housing fixing means is made with a cutout to accommodate the aforementioned rotary friction damper, two component installed on breeding the type mentioned in the rack, which ensures the compactness of the mechanism.

For a clear understanding and easy implementation of the invention will now be described one variant of implementation, with reference to the accompanying drawings, in which:

Figure 1 shows the lever in question, citrus juicer, along with a rack to which the lever pivot is attached.

Figure 2 shows a view in section of the fastening of the fixing means in the rack, while the lock is in rosapenna position.

Figure 3 also shows the cross-section of mounting the locking means in the rack with lock in locked position, and

Figure 4 shows the fixing rotary friction damper, the firmware socket type in the locking means in the rack.

Referring now to the drawings, we see that figure 1 shows the stand 10 with the lever 20, a swivel attached to position 30. The rotary shaft 40, with the containing a series driven by the user, the actuator locking mechanism, acts of the rack 10 and is designed for installation knurled handles or other forms of interactive element that facilitates user interaction with the drive.

It is clear that the stand 10 is rigidly attached to the chassis citrus juicer above-described type, in which case supports vertical nozzle and accommodates the electric motor and operate the shaft with a pre-installed nozzle, so that, using the motor to rotate the nozzle, you could extract the juice of the halves of citrus fruit, pressed against the nozzle. The lever 20 is rotatable attached to the body (through the rack 10) and carries a clamping element (not shown)adapted for compression of the fruit to the nozzle and may also cover or closure element (not shown)for closing the active elements juicer when juicing. The lever 20 has a raised position in which the clamping element is disconnected from the nozzle and can be lowered from the raised position into the working position, in which it can be used to facilitate compression of the fetus to the nozzle. However, due to the fact that the elements of citrus juicer, with the exception of the rack 10 and arm 20 (together with the components directly associated with them, which must now be described in detail), are not relevant to this izaberete the July and may have any convenient form, here it is not shown and is not further described.

Referring now to figure 2 and 3, we see that the lever 20 is rotated relative to the rack 10 about the axis 11. The axle 11 is surrounded by a torsion spring (not shown) and zapfino part 21 of the lever 20, with the torsion spring is connected to the pin 21 and the axle 11 to adjust the lever 20 in the raised position, wherein the lever forms a substantial obtuse angle with the stand 10, providing clearance for placing the fruit on the attachment.

The locking means 50 is installed in the concave region of the rack 10 for sliding movement relative to the rack, as will now be described. The locking means 50 includes a fixed housing part 51 which hold the sliding carriage 52, which in turn supports the protruding latch 53. The release of podporuje relative to the carriage 52, the spring (not shown) draws the latch 53 to the outside of the carriage 52 in the direction of the extended or protruding position shown in figure 2 and 3. However, the application of sufficient mechanical force to the latch causes a partial retraction of the latch 53 in the carriage 52 for reasons which will become clear later.

Figure 2 shows the locking means 50 in the flow state, intended for normal use of the extractor, in which the latch 53 is released from the groove or recess 22 in the outer is poverhnosti pin 21 of the lever 20. In this state, the lever 20 is brought into a raised position above the torsion spring, but can be lowered manually by the user by simply pressing the lever. On the other hand, figure 3 shows the locking means in the locked condition, designed for storage or transport, in which it locks the lever 20 in a lowered position, where he in this embodiment, forms an essentially right angle with the stand 10. However, in other embodiments, implementation of the angle formed by the arm with stand, can be acute or obtuse. In any case, in the locked state, the protruding latch 53 comes into engagement with the groove or recess 22, and prevents the movement of the lever 20 in the raised position, despite the effort of finishing the above-mentioned torsion spring. This lock lever 20 is convenient for storage and transportation of citrus juicer, as the lever is fixed at the height of other components of the extractor and is firmly held in a compact position.

The user can control the locking means 50, by manipulating the actuator 40, thus holding the lever 20 in the lower position. Alternatively, the user may prefer to manipulate the actuator 40, the lever is lifted and then lowered manually, then the spring, coupled with what Ekstrom 53, allows the latch to move about the axle 21, moving to her or to the carriage 52, if necessary, until the latch 53 snaps into place in the groove or recess 22.

Thus, the lever can be locked into the rack 10 in a lowered position relative to the housing, which, as mentioned above, supports or contains all the active elements extractor, allowing you to easily input and output of the juicer from operating mode and stored without excessive demands on the overall height and without the risk of damage to the arm and/or other components when hitting arm on a hard surface or edge, for example, those that have a bottom cabinets or shelves that can be attached above the work surface, using a juicer.

An additional characteristic of the invention is the provision of damping means, which can prevent too rapid rise of the lever in its fully raised position by the impact of the above-mentioned torsion spring acting between the rack 10 and the lever 20, pushing or even physically stop the juicer by sudden stop when it reaches the extreme upper position of turn.

In this example of the invention, as shown in figure 4, the fixed body part 51 of the retainer 50 has such a waveform as shown position the Oia 54, to form a space in which may be mounted rotary friction damper 60, the damper has an outer gear 61 connected to the axle, which supports a variety of blades rotating in a viscous fluid enclosed in the housing 62. Thus, body part 51 of the locking means 50 is made with a cutout, as shown by the position 54, specially designed in size and adapted for installation mentioned rotary friction damper 60, in accordance with which the locking means 50 and the rotating friction damper 60 socket type installed in the rack 10 so that both could separately to interact with the corresponding components of the lever 20, thereby providing a useful compactness of the layout.

The gear 61 of the damper 60 is adapted to drive through rakoobraznogo transmission 23, which is located on the pin 21 of the lever 20, which occurs when the lifting arm relative to the rack 10, with the rotation of the blades in the housing 62 of the damper 60, caused by the clutch gear 61 with the transfer 23, prevents the resistance of the viscous fluid in the housing 62, which provides a damping effect, forcing the lever to rise slowly and manageable, and also to smoothly stop in the fully raised position.

It is clear that can be astanoilcompany damping means within the scope of the invention.
