Known revealing the device for a sash window or door, in which between 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 are made 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 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 the use of 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 [5].

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 sash 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 gribovidne axle wears it the end of this unit.

Known locking device for 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 automatically locked in the hole of the lock body when the door is closed 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 [5].

Known protected from hacking automatically locking device for holding the door in closed or partially ajar position, intended for use both inside and leaving it. It is installed on the door from the inside of the room and contains a lock blocking access from the outside to lock it the borehole 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 castle, which is connected to a lock 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 completely on the inside of the premises is necessary to release the locking element from the latch through the extension arm fixed key or through a keyhole with a key from him, and to 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 be the opening from the outside. Inside the room you can use the handle with which you want to move the T-shaped end of the slit element, 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 [6].

The disadvantages of the known devices [5] and [6] 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 are not 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.

A device for exhaust gas is anichini door opener, contains a hard link 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 [7].

The disadvantages of this device is the 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 of the lever also has a high structural complexity, as it should provide dup eczema lever not only rotate, but 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.

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 voltage is the making of a longitudinal groove clamping ledge. Interacting with each other, the stop and the clamping protrusion aligned with each other so that they are made 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 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 greater the number of parts, besides 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 sash 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 of the 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 connected to the 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 bar with a groove having an extension at one end, and holes for fasteners (screws or bolts) for rigid attachment striker on the door RA is the expansion 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 clues in the groove to ensure a limited priotkryvaya leaf and extract spherical or mushroom-shaped thickening of the leads of the longitudinal slits to provide a shutter fully[9], [10].

This known device has the following two technical flaws. First, it can only be used for gates that open into the room, as the locking bar 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 as wood, and, moreover, the 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 open the second door or window, which contains a base, the locking element, the locking bar and the connecting member, the connecting element is made of flexible material and narashima connected with the base and the locking bar by means of a conical clamping screw. 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 form 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 also inconvenience the communication with the visitor (by) and obtain from them (such as the postman or courier) to small objects or packages.

Known to be the most similar in design to limit the angle of rotation of the sash, as adopted 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 be attributed, then, is that the lead is spherical or mushroom-shaped thickening of the edge surface, on which it is rigidly fixed. This leads to the fact that manufacturers and suppliers are recommended 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.

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 fault the expansion of the field of operation of the device by providing 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, the object of the invention is the provision of manufacturability of the device.

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 the device for limiting the angle of rotation of the leaf containing the lead and configured to pivotally mount the plate with a groove having an extended end facing the hinge fastening, hook executed at the end of the bolt with the possibility of longitudinal movement and passing through the extended end of the groove lining, as well as with the possibility of snagging the edge of the groove throughout its length with the opening of the door.

To solve the task to ensure the manufacturability, including the use of bolt both square and circular cross-section, a catch is made at the end of the bolt on which is rigidly fixed to the handle, the bolt with the possibility of longitudinal movement housed in a guide housing, which is made a longitudinal bore for movement along the handle of the latch, when this pad is made in the form of a plate, and the hinge done is in the form of a door or window hinges.

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

Indeed, the elimination of technical disadvantage of the prototype in the form of a prominent hook with spherical or mushroom-shaped thickening of the edge plane of the mounting on the sash or jamb is provided the use of rolling (with the possibility of longitudinal displacement) of the latch with the hook on the end, is arranged to pass through the extended end of the groove lining, as well as with the possibility of snagging the edge of the groove throughout its length with the opening of the door. The task of ensuring the manufacturability, including the possibility of making the bolt of square and circular cross-section, solved due to the fact that the catch is made at the end of the bolt with fixed handle, a bolt with the possibility of longitudinal movement housed in a guide housing with a longitudinal bore for movement along the handle of the latch, when this pad is made in the form of a plate, and the hinge is made in the form of a door or window hinges. For further safe operation is ensured by the fact that the hook is configured to engage both edges of the groove. Application is the totality of restrictive (known from prototype) and new features allows you to nominate a hook bolt through the extended end of the groove in the plate, turned around pre swivel mount until it touches the jamb or the end of the guide housing (for outward opening sash), then when opening the sash molding groove fits over the bolt, and the hook is engaged with both edges of the groove, preventing possible attempt at ajar the door to remove the pad with hook and unauthorized to enter the premises. Thanks this fixed the technical shortcomings of the prototype in the form of constantly sticking out clues with spherical or mushroom-shaped thickening. Consequently, provided with the expansion of the scope of the device for limiting the angle of rotation of the sash, as it is with the same success can be used for casement, inward opening, and leaf, outward opening, and provided with improved external (aesthetic) to the device type.

Device for limiting the angle of rotation of the 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 fo the mules of the invention.

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