A device for limiting the door opening, containing a rigid connection in the form of two shoulders of the lever, one end of which is secured a latch cooperating with the guide mounted on a stationary element of a door and door jamb or wall. On the other end of the two shoulders of the lever reinforced heel, which has the possibility of going beyond the door and interact with the door jamb. Two shoulders lever fortified by a hinge that allows rotation, and limited linear movement of the two shoulders of the lever relative to the door leaf. Two shoulders lever is spring-loaded relative to the door leaf by means of an elastic element (spring compression) and with a lever interacts with the drive mechanism, which is equipped with a retractable bolt, locking the latch in its closed position, the drive mechanism has two modes: mode door open with restriction of rotation, and the mode of opening the door without limitation of rotation angle [5].

The disadvantages of this device include high complexity of its design and, as a consequence, not a high operational reliability. The complexity of the device due to the large number of parts and a large number of elements, joints, one of which is the hinge mounting two shoulders growling is and has a high structural complexity, as should provide two shoulders lever not only rotate, but also limited linear movement relative to the door leaf. In addition, the device is complicated by the presence of the drive mechanism, the construction of which is not disclosed and is likely Electromechanical node. In addition, the drive mechanism reduces the safe operation, since it allows unauthorized entry to the premises because of an erroneous opening the door, if the pre-drive mechanism is not transferred from the mode of opening the door without limitation of rotation angle in the mode of opening the door with the restriction of the rotation angle.

A device for blocking doors, giving the possibility of partial priotkryvaya door blocking further opening ajar door, mounted inside on the door and the doorframe with the possibility of using the device indoors and outside and castle and containing the elements to lock the door with the access key to lock the locking device outside the room through the gap between the slightly opened door and door frame when the door is locked, and when the door is open to the elements for locking the door opening are folded by means of a spring at each other and at right angles thereto is a machine which Cesky locked in the hole of the lock body when closing the door element, when this is placed in the hole of the lock body mounting bolt made available after locking element in the hole of the lock body and the locking device has a diversion from the castle to open inside the room [6].

Known protected from hacking automatically locking device for holding the door in closed or partially ajar position, intended for use both inside and outside. It is installed on the door from the inside of the room and contains a lock blocking access from outside to his the keyhole through the gap between the door and door frame when the door is locked. The device also includes a stationary fixed element and consistently associated with the axes of the rolling elements in the form of levers that are in an unusable state by means of springs automatically return and revert to their original locked position. The element that is lockable element is automatically locked in stationary fixed casing of the lock when the door is closed with the latch. At this time, the lock that is associated with the locking mechanism with a keyhole at the outside of the door, hooked on the tab on the item and hold it in a stationary position in which the door is held in closed position. To open the door on the activities inside the premises must release the locking element from the latch through the extension arm fixed key or through a keyhole with a key from him, and for priotkryvaya doors should be partially exempt from the lead lock the tab key through the keyhole on the outside of the premises or manually from the inside of the room. Locking device from the inside of the room is the tap handle, which is protected by the housing and inaccessible from the outside through the half opened and locked the door and is designed to regulate the gap priotkryvaya door for holding the door in closed position without opening the outside. Inside the room you can use the handle with which you want to move the T-shaped end into the slot of the item, then turn the handle 90 degrees and lock at the desired level on the holder. So you can adjust the gap priotkryvaya door or hold it in closed position without opening outside [7].

The disadvantages of the known devices [6] and [7] include the complexity of their design and inconvenience of operation. The complexity of the design due to the large number of parts, some of which are complicated in shape and ethnologica in manufacturing, and a large number of joints between them, as well as the presence of additional key lock. The inconvenience of operation associated with the need to have the key to the additional lock. In addition, these devices lack is reliable in operation, since the attacker can easily bring them down a simple introduction into the keyhole additional lock foreign object (for example, chip matches)that will lead to the necessity of the power of opening the device, so as to remove the foreign body from the keyhole for more castle will be impossible due to the specially provided extremely difficult access to the keyhole additional lock.

It is known which discloses the device for a sash window or door, in which between the sash and frame there is the stopper of the rotation angle of the sash relative to the frame. The limiter consists of an opening lever which is mounted to rotate respectively on the sash and frame and are made from plates. Each plate has a longitudinal groove and located at the front on the distance from the plane of the thrust plate ledge. Each thrust plate includes a protrusion in a longitudinal groove of the other plate. Resistant ledge of each plate is located adjacent to the stop for the other of the thrust ledge. The axial protrusion is formed by a bent section of the plate. From the end of the longitudinal groove should be oriented in the longitudinal direction of the longitudinal groove of the clamping ledge. Interacting with each other, the stop and the clamping protrusion aligned with each other so that they will who are satisfied with the possibility of passing each other when the elastic deformation of the clamping ledge. This device is provided for fixing the valve in its open position in a small structural space. Located on the sash or frame, the pivot point formed by the hole in the plate and passing through the hole mushroom pin, extended head which is covered by a bottom locking lever. The locking lever mounted on revealing the lever can be rotated or offset and using a separate section covers the bottom with the blocking effect of the mushroom-shaped head. The locking lever in the locking position is aligned position with the opening lever. The locking lever in its locking position is fixed by the locking element. It should be noted that reveals the device is preferably applicable to the valves, which are made to rotate around the lower horizontal axis. However, it can also be provided that should be limited rotary movement of the leaf, which is made with the possibility of rotation around the lateral axis [8].

The disadvantages of this device include increased design complexity due to the large number of parts having a complex shape. Another disadvantage of this device include the fact that the device is fully positioned in the gap between the jamb and STV is rcoi in the closed position of the sash, which requires increased the width of the gap between the jamb and sash in its closed position, at least in the placement of this device is that you can't always run to the door. In addition, the drawback of the device is low security to prevent unauthorized entry into the room through the slightly open door, because the attacker can easily be deduced from the fixed state and turn the locking lever to withdraw from the mushroom-shaped pins are put on her end plate of this device.

A device for limiting a rotation angle of the leaf, called "chain door". Chain door has a chain, one end (the last link) is attached to the base plate with holes for fasteners (screws or bolts) to secure the chain on the lintel, and on the other end of the chain is fixed to the hook with a spherical or mushroom-shaped thickening at the end. The device also includes a locking plate with a groove having an extension at one end, and holes for fasteners (screws or bolts) for rigid fastening of the locking plate on the flap extension of the groove in the opposite edge of the leaf direction. The expansion in the groove serves to introduce spherical or mushroom-shaped thickening of the hook in engagement with the kr is s groove to ensure a limited angle of rotation of the sash and excretion of spherical or mushroom-shaped thickening of the hook from engagement with the edges of the groove to provide a shutter fully [9], [10].

This known device has the following three technical flaws. First, it can only be used for gates that open into the room, as the locking plate cannot be mounted on the jamb because of the rather large its length due to the great length made in her groove, and the jamb wooden, especially metal has a significantly smaller cross-section thickness. Secondly, the chain can eat the cutters, as the links of the chain, as well as other parts of the device, in practice, are made of annealed steel and plastic after fabrication of the device is not subjected to quenching. Thirdly, when powerful enough pull some chain link (the weakest) may rupture due to the small cross-section and internal defects (microcracks or microraman) in the metal. The first technical deficiency leads to a decrease in the use of the device, and the second and third - decrease the safety of operation.

A device for fixing the slightly opened door or window, which contains a base, the locking element, the locking bar and the connecting member, and is characterized by the fact that the connecting element is made of flexible material and narashima connected with the base and the locking bar by means of a conical clamping VI is the same. As the coupling element in the device can be used in metallic and non-metallic rope (cable). Striking plate has a shaped hole corresponding to the shape of the T-shaped bolt, the locking grooves for additional (second degree) fixing T-shaped bolt in the locked position and the plunger spring [11].

The technical disadvantage of this device is that the attacker can easily get the T-shaped locking bolt is disengaged from the locking bar, putting his hand in the doorway and turning 90 degrees to the T-shaped bolt, pressing him against the action of a spring-loaded plunger, which dramatically reduces the safe operation of this device, because the attacker will not be able to withstand children, women and the elderly. To resolve this technical drawback maximum lumen (opening) door ajar must be sufficiently narrow so as not climbed a palm, for example not more than 4 But with such a narrow lumen (opening) door ajar is not only small review, but the inconvenience of communicating with visitors (visitors) and obtain from them (for example, mail carriers or couriers) delivered small objects or packages.

Known to be the most similar in design to limit the angle of rotation of the sash, the principle is the same for the prototype, dubbed the "chain stitch"contains a pad with swivel mount, made in the form of an elongated loop with a groove having an extension at the end facing the hinge mount (essentially locking plate that performs the same functions as in the above-described device "chain door", but not rigidly fixed, and the hinge, i.e. with the possibility of rotation). The pad with the possibility of rotation (hinge bracket) is attached to the jamb. The device also contains a clue with spherical or mushroom-shaped thickening, which is rigidly mounted on the sash inward opening, with the possibility of snagging her pads by putting on pads the advanced end of the groove on the spherical or mushroom-shaped thickening of the hook when the sash is fully closed. If you then open the sash inside the hook is moved into the groove lining and spherical or mushroom-shaped thickening comes into engagement with the edges of the groove, providing a limited angle of rotation of the leaf (in fact the clue here performs the same functions as the lead in the device chain door", only stationary) [12].

The technical disadvantage of this device should include the fact that the lead is spherical or mushroom-shaped thickening at the edge of the surface on which it is rigidly fixed. Utopistic to what manufacturers and suppliers recommend to install this device only on the doors, inward opening, as when installed on a leaf, outward opening, a hook with a spherical or mushroom-shaped thickening need to be fixed firmly on the post. While the lead together with spherical or mushroom-shaped thickening is constantly advocate for the inner edge of the jamb, which not only has an aesthetic appearance, but also reduces the width of the pass door frame, and also creates the danger of snagging him passing by people. Thus, the disadvantages of this device are low scope (only for gates opening inwards)and unaesthetic appearance and increased risk of exploitation when installed on doors, Windows that not only outside but also inside.

The technical disadvantage of the prototype should also be noted that the strap after putting on the advanced end of the groove on the protruding spherical or mushroom-shaped thickening of the lead remains uncommitted and if mistreated (e.g. in a hurry spherical or mushroom-shaped thickening of the clues are not fully passed through the extended end of the groove in the plate), and subsequent opening of the sash plate may not be in engagement with the spherical go mushroom-shaped thickening of clues that will lead to the possibility and unauthorized entrance to the room. Also with the dramatic collapse of the sash by an attacker plate obtained from jerky pulse may be off spherical or mushroom-shaped thickening of the lead and reverse the sharp jerk of the door can fully open, revealing a passage for unauthorized entry into the premises. In addition, it is known fixture in the form of a thin elastic metal plate with a groove on the end, which the attacker inserts between the hinge plate and the edge of the sash, wearing a groove on the hook, then abruptly shuts the door, while at the time of full closing of the sash, this elastic plate is bent and resets the pad with the lead, after which the door abruptly opens, revealing an attacker unfettered access to the premises in Internet hosted video [13].

Thus, specified in the previous paragraph, the technical disadvantage of the prototype reduces the safe operation of the device.

Object of the invention is the elimination of technical disadvantage of the prototype described above and consists in the fact that one of the parts of the prototype (spherical or mushroom-shaped thickening of the lead is continuously extends over the edge of the surface on which it is attached, and is also associated with the elimination of this technical disadvantage of extending the operation of the device by both the cookies the possibility of using it as for the valves, inward opening, and shutters that open to the outside, as well as improving the safety of its operation and improve its aesthetic appearance.

In addition, another object of the invention is the elimination of technical disadvantage of the prototype, which consists in the absence of reliable fixation of the flap in the position in which she wears spherical or mushroom-shaped thickening leads before opening the sash, and also associated with the elimination of this technical disadvantage of increasing the safety of operation of the device.

In addition, another objective is to ensure the manufacturability of the steering lock of the door.

Another object of the invention is the extension of technical tools for similar purposes.

The task of the invention is solved by the fact that in the limiting angle of the leaf containing the lead and configured to pivotally mount the plate with the slot, the hook is executed at the end of the bolt with the possibility of longitudinal displacement, rotation, passing through the groove pads and gear after turning over the edge of the groove throughout its length, the bolt is rigidly fixed to the handle and it is housed in the guide housing, which made the winding slot, consisting of the transverse bore and connected with its longitudinal ends the wells, located in opposite directions from the transverse bore, with the possibility of moving them along the handle of the latch, however, on the pads, turned to bolt, performed a longitudinal ledge.

To increase convenience and improve conditions on the side of the lining facing the bolt, made two longitudinal protrusions on either side of the longitudinal slots, each longitudinal protrusion is made with a slope facing the hinge mountings.

To ensure the manufacturability pad is made in the form of a plate with a groove, the hinge is made in the form of a door or window hinge and longitudinal ledges with gradients made in the form of bent 90 degrees to the longitudinal edges of the plate.

New features of the invention in conjunction with the known characteristics allow to solve problems of the invention, all of these features form an indissoluble whole, which solved the problem of the invention.

Indeed, the elimination of technical disadvantage of the prototype in the form of protruding lead with spherical or mushroom-shaped thickening of the edge plane of the mounting on the sash or jamb implemented by using a bolt with a hook on the end and a handle, the execution of the bolt with the possibility of longitudinal movement and rotation of the guide body, the guide body is made of a winding slot, consisting of the transverse bore and connected with its longitudinal ends of the wells located in opposite directions from the transverse bore, with the possibility of moving them along the handle of the latch, which allows not only to push the hook through the slot in the plate, but then to turn it, when this plate is fixed catch on the bolt even before the shutter opening and can not be reset by an attacker with no hook at sharp movements when opening and closing the sash or when using elastic metal plate with a groove on the end of the above source of information [13], and when opening sash longitudinal ledge pads, interacting with the jamb, or the end of the guide housing (sash opening outwards), or with the edge of the leaf or the end of the guide housing (leaf opening inwards) locks the handle of the bolt in the longitudinal bore, preventing possible attempt to rotate the lead and withdraw it from engagement with the plate with subsequent unauthorized entry into the room. Thanks this fixed the technical shortcomings of the prototype in the form of constantly sticking out clues with spherical or mushroom-shaped thickening in the absence of a reliable fixation of the lining spherical or mushroom-shaped thickening of the clues before the Scrivania sash. Consequently, provided with the expansion of the scope of the limiter angle sash, as it with the same success can be used for casement, inward opening, and leaf outward opening, and provided increased operational safety and improved external (aesthetic) form of steering lock of the door. If the pad is made of two longitudinal tabs (one on each side of the groove in the plate), it removes a small amount of skew plates with the opening of the sash and improves the conditions of operation of the limiter angle sash, and having on each longitudinal protrusion of the slope, facing the swivel mount allows you to open the door immediately after turning the lead with the handle of the bolt until it stops before the end of the transverse bore, because if you then open the sash due to the interaction of slope and longitudinal projections with a jamb or the end of the guide body is smooth pulling the handle of the bolt in the longitudinal hole on the guide housing than automatically is provided to prevent unauthorized turning of the bolt with hook and excretion of lead from engagement with the plate, and with it increases the convenience and safety of operation. Performing a lining in the form of a plate with a tongue which, the articulation in the form of a door or window hinges, and longitudinal ridges with slopes in the form of bent 90 degrees to the longitudinal edges of the plate ensures high manufacturability of the steering lock of the door.

The limiter angle sash, being new, expanding Arsenal of technical means for a similar purpose, which is one of the objectives of the invention.

Thus, all these objectives of the invention is solved by a set of known (restrictive) and new features.

It should be noted that all the main objectives of the invention are achieved when using all the features of independent claim.

The preferred form of execution of certain features of the invention are specified in dependent claim.

The limiter angle sash includes a plate 1 made of a steel plate with a groove 2 of the same width throughout its length and swivel mount 3 made in the form of a hinge can be rotated pads 1 and is rigidly fixed by means of the fastener 4 on the 5 fold opening to the outside. On the ukladka 1 by the reflection of its longitudinal edges at 90 degrees is made by hand, facing the bolt, the longitudinal protrusions 6 slope 7 (Fig shows a variant in which the longitudinal protrusions 6 are not gradients), addressed to the hinge bracket 3. The limiter angle of the leaf also contains a bolt 8, which is placed in the guiding body 9 with the possibility of longitudinal displacement and rotation. In the guiding body 9 is made of the transverse bore 10 and two longitudinal bore 11 and 12 connected to the ends of the transverse bore 10 can move along them handle 13 rigidly mounted on the bolt 8, one end of which the hook 14 with the possibility of engagement with the edges of the groove 2. The guide body 9 by means of fixing elements 15 is rigidly fixed to the casing 16 with the passing of the lead 14 when his nomination to the outside of the guide body 9 through the slot 2 and the engagement hook 14 when turning over both longitudinal edges of the groove 2 along its length.

The limiter angle of the leaf, outward opening, use the following.

The pad 1 with the swivel mount 3 by means of fasteners 4 (bolts or screws) rigidly fixed to the door 5. On the post 16 by means of fasteners 15 are rigidly secured to the guide body 9 of the bolt 8 with a handle 13 and hook 14 with the passing of the latter through the slot 2 in the plate 1 after the rotation of the pads 1 articulated around the rise 3 to contact with the jamb 16 or the end of the guide body 9. When you need to open the flap 5 with providing a limited angle of rotation of the pad 1 is turned around the hinge attachment 3 to contact with the jamb 16 or the end of the guide body 9. Then the bolt 8 by the handle 13 is moved along the guide body 9 to output lead 14 to the outside through the groove 2, and the handle 13 is moved along the longitudinal bore 11 to the exit and entry into the transverse bore 10. Then the handle 13 is moved along the transverse bore 10 to exit and entry into the longitudinal hole 12, and the bolt 8 is rotated around its axis by 90 degrees together with the hook 14, which is engaged with both edges of the groove 2 and secures the plate 1 from possible unauthorized rotation around the hinge attachment 3, for example, when an intruder tries to reset the pad 1 by a sharp collapse of the sash 5 and then suddenly her opening. Then open the shutter 5 locks (locks and inner bolt, not shown) and lift the flap 5 on the length of the groove 2. In the beginning of the turning of the leaf 5 of the plate 1 for the lead 14 through grades 7 interacting with jamb 16 or the end of the guide body 9, smoothly pulling a bit of a bolt 8 with a handle 13, which moves in the longitudinal hole 12, is securely zafy the line against unauthorized rotation due to the interaction of the longitudinal projections 6 with the casing 16 or the end of the guide body 9, consequently prevents the possibility of rotation of the bolt 8 and excretion of lead 14 from engagement with the edges of the groove 2 of the plates 1, which guarantees against unauthorized entry to the premises.

In the absence of gradients 7, the longitudinal protrusions 6 (Fig) after moving to another handle 13 along the transverse bore 10 need pickguard 1 pull up to the stop from the jamb 16 and move the handle 13 to the end along the longitudinal bore 12, thereby locking the handle 13 from possible unauthorized rotation, with longitudinal projections 6 will be released from the zone of possible engagement with the casing 16 or the guide body 9. After that you open the latches (not shown) at the shutter 5 and turn it out to the length of the groove 2 in the plate 1.

To return the plates 1 in the original condition in which it is leaning against the door 5, the door 5 can be opened fully, you must perform the above steps with the structural elements of the limiter angle sash in reverse order.

The use of steering lock casement, inward opening, is carried out by performing the same sequence of steps as for the leaf, outward opening, with the difference that the plate 1 through the hinge 3 by means of the fastener 4 is rigidly attached to the jamb 16 of the longitudinal protrusions 6 in the direction of the tworki 5, which is rigidly fastened by means of fasteners 15 to the guide body 9 with the bolt 8.

The limiter angle sash can be widely used for doors of dwellings, opening outwards as well as inwards, to prevent penetration into the premises of criminals posing as law enforcement officials, institutions of social and medical care, post offices, companies, property managers, trade organizations, and so forth.

The limiter angle sash can also be widely applied for office doors when, for example, on regime security rules you want to receive correspondence for painting without passing in the location of the courier or postman.
