A device is known for locking for doors, making it possible to partially open the door with blocking the further opening of the ajar door, installed inside the room on the door and door frame with the possibility of using the device indoors and outdoors and containing a lock and elements for blocking the opening of the door with key access to the lock a locking device outside the room through the gap between the ajar door and the door frame when the door is locked, and with the door open Cops for blocking the door opening are folded with a spring on top of each other, and at a right angle to them is an element automatically locked in the opening of the lock case when closing the door, while the fixing bolt located in the hole of the lock case is made inaccessible after locking the element in the opening of the lock case, and the locking device has a tap from the lock for opening from the inside of the room [5].

Known protected from breaking automatically locking device for holding the door in the closed or partially ajar position, intended for use both from the inside and outside. It is installed on the door from the inside of the room and contains a lock with access from outside to its keyhole through the gap between the door and the door frame with the door locked. The device also contains a fixed element and successively connected by axes movable elements in the form of levers, which, when inoperative, are automatically returned by means of springs and assume their initial fixed position. The element, which is a lockable element, is automatically locked in the fixed lock lock case when the door is closed with a latch. At this time, the lock, which is connected by a lock mechanism to the keyhole on the outside of the doors, is engaged by a protrusion on the element and holds it in a fixed position, in which the door is held in a closed position. To open the door completely from the inside of the room, you need to release the lockable element from the latch using the remote handle of a permanent key or through the keyhole with the key to it, and to open the door you must partially release the protrusion of the key with the key through the keyhole outside the room or manually with the inside of the room. The locking device on the inside of the room has a retract with a handle that is protected by a housing and is not accessible from the outside through an ajar and locked door and is designed to control the gap of the door ajar and to keep the door in a closed position without the possibility of opening from the outside. From the inside of the room, you can use the handle, with which you need to move the T-shaped end in the slot of the element, then turn the handle 90 degrees and fix it at the desired level on the holder. So you can adjust the gap ajar doors or keep it in the closed position without the possibility of opening from the outside [6].

The disadvantages of the known devices [5] and [6] include the complexity of their design and the inconvenience of operation. The complexity of the design is due to the large number of parts, some of which are complex in shape and low-tech in manufacturing, and the large number of joints between them, as well as the presence of an additional key lock. The inconvenience of operation is associated with the need to have a key to an additional lock. In addition, these devices are not sufficiently reliable in operation, since an attacker can easily disable them by simply introducing an additional lock of a foreign object into the keyhole (for example, a fragment of a match), which will lead to the necessity of opening the device by force, since removing the foreign body from the lock additional lock wells will not be possible due to the specially provided extremely difficult access to the keyhole of the additional lock.

A device is known for limiting the opening of a door, containing a rigid connection in the form of a two-shouldered lever, at one end of which a latch is fixed, interacting with a guide mounted on a fixed door element - a door jamb or a wall. A heel is fixed at the other end of the two-shouldered lever, which has the ability to go beyond the door leaf and interact with the door jamb. The two-shouldered lever is reinforced by a hinge that allows for twists and limited linear movements of the two-shouldered lever relative to the door leaf. The two-arm lever is spring-loaded relative to the door leaf by means of an elastic element (compression spring) and by means of a rod interacts with a drive mechanism, which is equipped with a retractable bolt that locks the latch in its closed position, while the drive mechanism has two modes: the door opening mode with a limited rotation angle and door opening mode without limiting the angle of rotation [7].

The disadvantages of this device include the high complexity of its design and, as a result, insufficiently high operational reliability. The complexity of the device is due to both a large number of parts and a large number of their articulation elements, one of which is the hinge of the two-arm lever mounting also has increased structural complexity, since it must provide the two-arm lever not only with rotation, but also with limited linear movements relative to the door leaf. In addition, the device is complicated by the presence of a drive mechanism, the design of which is not disclosed and is, most likely, an electromechanical assembly. In addition, the drive mechanism reduces the safety of operation, as it allows unauthorized entry into the room due to erroneous opening of the door wide open if the drive mechanism is not previously transferred from the door open mode without limiting the angle of rotation to the mode of opening the door with limiting the angle of rotation.

A disclosing device for a sash of a window or door is known, in which a limiter of the angle of rotation of the sash relative to the frame is provided between the sash and the frame. The limiter consists of a opening lever, which is mounted with the possibility of rotation respectively on the sash and frame and is made of plates. Each plate has a longitudinal groove and a persistent protrusion located in front of the plate at a distance from the plane of the plate. Each plate enters a persistent protrusion into the longitudinal groove of the other plate. The abutment protrusion of each plate is adjacent to the abutment for another abutment protrusion. A thrust protrusion is formed by the bent portion of the plate. A clamping protrusion oriented in the longitudinal direction of the longitudinal groove should protrude from the end of the longitudinal groove. Interacting with each other, the stop and the clamping protrusion are coordinated with each other so that they are made with the possibility of passing past each other with elastic deformation of the clamping protrusion. This device provides for the locking of the sash in its open position in a small structural space. The swivel joint located on the sash or frame is formed by a hole in the plate and a mushroom pin extending through this hole, the extended head of which is covered from below by the locking lever. The locking lever is mounted on the opening lever with the possibility of rotation or displacement and, using a separate section, covers the mushroom head from below with a blocking effect. The locking lever in the locking position is in a combined position with the opening lever. The locking lever is locked in its locking position by a locking element. It should be mentioned that the disclosing device is preferably applicable for flaps that are rotatable about a lower horizontal axis. However, it can also be provided that the rotational movement of the sash, which is configured to rotate around the lateral axis [8], should be limited.

The disadvantages of this device include the increased complexity of the design due to the large number of parts, which also have a complex shape. Another disadvantage of this device can be attributed to the fact that the device is completely located in the gap between the jamb and the sash in the closed position of the sash, which requires an increased width of the gap between the jamb and the sash in its closed position, at least at the location of this device, which not always possible for doors. In addition, the disadvantage of the device is low security to prevent unauthorized entry into the room through an ajar door, since an attacker can easily remove from a fixed state and turn the locking lever, followed by removing the end of the plate of the device worn on it from the mushroom pin.

A device for limiting the angle of rotation of the sash, called "door chain". The door chain contains a chain, which at one end (the last link) is attached to the base plate with holes for fasteners (screws or screws) to fix the chain to the jamb, and a hook with a spherical or mushroom-shaped thickening is fixed at the other end of the chain. The device also contains a locking plate with a groove having an extension at one end and holes for fasteners (screws or screws) for rigidly fixing the locking plate on the casement by expanding the groove in the opposite direction from the edge of the casement. The expansion in the groove serves to introduce a spherical or mushroom-shaped thickening of the hook into engagement with the edges of the groove in order to provide a limited angle of rotation of the leaf and to remove the spherical or mushroom-shaped thickening of the hook from the meshing with the edges of the groove to ensure that the leaf opens completely [9], [10].

This known device has the following three technical disadvantages. Firstly, it can only be used for shutters that open into the room, since the striker plate cannot be fixed on the jamb due to its sufficiently long length due to the large length of the groove made in it, and the jamb is both wood and metal. has a significantly smaller transverse thickness. Secondly, the chain can be eaten with nippers, since the chain links, like the other parts of the device, are in practice made of annealed plastic steel and are not quenched after the manufacture of the device. Thirdly, with a sufficiently powerful jerk, some chain link (weakest) can break due to a small cross section and internal defects (microcracks or microcracks) in the metal. The first technical drawback leads to a decrease in the area of use of the device, and the second and third to reduce the safety of operation.

A device is known for fixing an ajar door or window, which contains a base, a locking element, a locking strip and a connecting element and is characterized in that the connecting element is made of flexible material and is permanently connected to the base and the locking strip by means of a conical fixing screw. As a connecting element in the device, a metal and non-metal rope (cable) can be used. The locking bar has a figured hole corresponding in shape to a T-shaped crossbar, fixing recesses for additional (second degree) fixing the T-shaped crossbar in the locked position, and a pusher with a spring [11].

A technical drawback of this device is that an attacker can easily disengage the T-bolt from the locking plate by sticking his hand in the doorway and turning the T-bolt 90 degrees, previously pressing it against the action of the spring-loaded pusher, which drastically reduces safe operation of this device, since the attacker will not be able to resist children, women and the elderly. To eliminate this technical drawback, the maximum clearance (opening) of the ajar door should be narrow enough so that the palm does not crawl, for example, not more than 4 cm. But with such a narrow clearance (opening) of the ajar door, not only a small overview is created, but also the inconvenience of communicating with the visitor (by visitors) and receiving from them (such as postmen or couriers) delivered small items or parcels.

The closest in design device for limiting the angle of rotation of the sash is known, adopted for the prototype, called the “chain loop”, containing a plate with a hinge, made in the form of an elongated loop with a groove having an extension at the end facing the hinge (in fact, this a locking plate that performs the same functions as in the above-described “door chain” device, but not fixed rigidly, but pivotally, that is, with the possibility of rotation). The swivel plate (thanks to the hinge mount) is mounted on a jamb. The device also contains a hook with a spherical or mushroom-shaped thickening, which is rigidly attached to the sash that opens inward, with the possibility of catching the lining for it by putting the lining with the extended end of the groove on the spherical or mushroom-shaped thickening of the hook with the sash completely closed. Upon subsequent opening of the sash inward, the hook moves into the groove of the lining and spherical or mushroom-shaped thickening engages with the edges of the groove, which ensures a limited angle of rotation of the sash (in fact, the hook here performs the same functions as the hook in the “door chain” device, only fixed motionless) [12].

The technical disadvantage of this device is that the hook acts as a spherical or mushroom-shaped thickening over the edge of the surface on which it is rigidly fixed. This leads to the fact that manufacturers and suppliers recommend installing this device only on leafs that open inward, since when installing on leafs that open outward, a hook with a spherical or mushroom-shaped thickening must be rigidly fixed to the jamb. At the same time, the hook along with a spherical or mushroom-shaped thickening will constantly protrude beyond the inner edge of the jamb, which not only has an unaesthetic appearance, but also reduces the width of the door frame passage, and also creates a danger of people passing by catching it. Thus, the disadvantages of this device include a low field of application (only for leafs that open inward), as well as an unaesthetic appearance and increased danger of operation when installed on leafs that open not only outward, but also inward.

The technical disadvantage of the prototype should also include the fact that the cover after putting on the extended end of the groove on the protruding spherical or mushroom-shaped thickening of the hook remains unsecured and in case of careless handling (for example, in a hurry the spherical or mushroom-shaped thickening of the hook is not completely passed through the extended end of the groove in the pad) and upon subsequent opening of the sash, the pad may not engage with a spherical or mushroom-shaped thickening of the hook, which will lead to the possibility of unauthorized access to omeschenie. Also, when a flapper slams the flap abruptly, the pad from the resulting jerky impulse can jump off the spherical or mushroom-like thickening of the hook and, when the flip is pulled back, the flap can open completely, opening the passage for unauthorized entry into the room. In addition, a device is known in the form of a thin elastic metal plate with a groove at the end, which the attacker inserts between the hinge plate and the edge of the sash, putting the groove on the hook, then abruptly slams the sash, while at the moment the sash is completely closed, this elastic plate bends and resets the plate with a hitch, after which the door swings open, opening an unhindered passage to the attacker, as a video has been posted on the Internet [13].

Thus, the technical disadvantage of the prototype indicated in the previous paragraph reduces the operational safety of the device.

The objective of the invention is to eliminate the technical disadvantage of the prototype described above and consisting in the fact that one of the details of the prototype (spherical or mushroom-shaped thickening of the hook) constantly protrudes beyond the edge of the surface on which it is attached, as well as the expansion of the field of operation of the device associated with the elimination of this technical disadvantage by providing the possibility of using it both for shutters opening inward and for shutters opening outward, as well as increasing the safety of its operation tion and improvement of its aesthetic appearance.

In addition, another objective of the invention is to eliminate the technical disadvantage of the prototype, which consists in the lack of reliable fixation of the lining in a position in which it is worn on a spherical or mushroom-shaped thickening of the hook before opening the sash, as well as improving the safety of operation of the device associated with the elimination of this technical disadvantage.

In addition, another task is to ensure the manufacturability of the manufacture of the lumen limiter opening the sash.

Another objective of the invention is the expansion of the arsenal of technical means for a similar purpose.

The objectives of the invention are solved by the fact that in the limiter of the opening clearance of the sash containing the hook and hinged plate with a groove, the hook is made at the end of the bolt with the possibility of longitudinal movement, rotation, passing through the groove of the lining and engagement after turning over the edge of the groove throughout its length, the handle is rigidly fixed to the bolt and it is placed in the guide body, in which a winding slot is made, consisting of a transverse well and longitudinal ends connected to its ends kvazhin disposed in opposite directions from the transverse borehole can be moved along them bolt handle, the laths on the side opposite the bolt, the longitudinal projection is configured to engage the hook.

To increase convenience and improve operating conditions, on the side of the lining opposite the bolt, two longitudinal protrusions are made on both sides of the longitudinal slot with the possibility of interaction with the hook, and each longitudinal protrusion is made with a slope facing the hinge.

To ensure manufacturability, the patch is made in the form of a plate with a groove, hinged fastening is made in the form of a door or window hinge, and longitudinal protrusions with slopes are made in the form of longitudinal groove edges bent 90 degrees.

New features of the invention in conjunction with the known features can solve the problems of the invention, while all these signs form an inextricable aggregate, due to which the objectives of the invention are solved.

Indeed, the elimination of the technical disadvantage of the prototype in the form of a protruding hook with a spherical or mushroom-shaped thickening over the edge of the attachment plane on the sash or jamb is ensured by the use of a bolt with a hook at the end and a handle, the execution of the bolt with the possibility of longitudinal movement and rotation in the guide body, for which purpose in the guide case a winding slot is made consisting of a transverse well and longitudinal wells connected to its ends located in opposite directions from the transverse well , with the possibility of moving the bolt handles along them, which allows not only to extend the hook through the groove in the pad, but also to rotate it, while the pad turns out to be a fixed hook on the bolt even before the sash is opened and cannot be dropped by the attacker during sharp movements when opening and closing the sash, or when using an elastic metal plate with a groove at the end described above from the information source [13], and when opening the sash, the longitudinal overhang of the lining, interacting on one side with a jamb or end face of the guide body and on the other hand with a hook (when opening the sash outwards) or with the edge of the leaf or end of the guide body on one side and a hook on the other side (when opening the sash inward), fixes the bolt handle in a longitudinal well, preventing a possible attempt to turn the clutch and disengage it from the lining with subsequent unauthorized entry into the room. This eliminated the technical disadvantages of the prototype in the form of a constantly sticking out hook with a spherical or mushroom-shaped thickening and in the form of a lack of reliable fixation of the lining with a spherical or mushroom-shaped thickening of the hook before opening the sash. As a result of this, the scope of application of the sash opening limiter has been expanded, since it can equally well be used both for the sash opening inward and for the sash opening outward, as well as an increase in operational safety and an improvement in the external (aesthetic) appearance of the angle of rotation limiter sash. Moreover, if two longitudinal protrusions are made on the overlay (one on each side of the groove in the overlay), this eliminates a slight misalignment of the overlay when opening the sash and improves the operating conditions of the sash angle limiter, and the presence of a slope on each longitudinal protrusion facing the hinge , allows you to open the sash immediately after turning the hook using the deadbolt handle until it stops, that is, to the end of the transverse well, since when the sash is subsequently opened due to the interaction of the slopes of the longitudinal of stupas with a hook, the bolt handle is smoothly pulled out into the longitudinal well on the guide body, which automatically prevents unauthorized rotation of the bolt with the hook and disengages the hook from the overlay, and at the same time increases the convenience and safety of operation. The implementation of the lining in the form of a plate with a groove, a hinge in the form of a door or window hinge, and longitudinal protrusions with slopes in the form of bent 90 degrees of the longitudinal edges of the groove of the plate allows for high manufacturability of the manufacture of a lumen limiter for opening the sash.

The lumen limiter for opening the sash, being new, expands the arsenal of technical equipment for a similar purpose, which is additionally one of the objectives of the invention.

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

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

A preferred embodiment of certain features of the invention is indicated in the dependent claims.

The sash opening clearance limiter comprises a cover 1 made of a steel plate, with a groove 2 of the same width along its entire length and a hinge 3 made in the form of a door hinge with the possibility of turning the cover 1 and fixed with fasteners 4 on the casement 5, which opens outwards . On the lining 1 by bending the longitudinal edges of the groove 90 degrees are made from the side opposite the bolt, the longitudinal protrusions 6 with slopes 7 (Fig. 15 shows a variant in which the longitudinal protrusions 6 have no slopes) facing the hinge 3. Lumen limiter The sash opening also contains a deadbolt 8, which is placed in the guide body 9 with the possibility of longitudinal movement and rotation. In the guide body 9, a transverse well 10 and two longitudinal wells 11 and 12 are located, located in opposite directions from the transverse well 10 and connected to the ends of the transverse well 10 with the possibility of moving along them a handle 13, rigidly fixed on the bolt 8, at one end of which is made the hook 14 with the possibility of engagement for both longitudinal edges of the groove 2, the longitudinal protrusions 6 and the slopes 7. The guiding body 9 with the help of fasteners 15 is rigidly fixed to the jamb 16 with the possibility of passing the hook 14 when it moving outward from the guide body 9 through the groove 2 and the engagement of the hook 14 when turning for both longitudinal edges of the groove 2.

The lumen limiter for opening the sash opening outward is used as follows.

The cover 1 with a hinge 3 using fasteners 4 (screws or screws) is rigidly fixed to the sash 5 with longitudinal protrusions 6 in the opposite direction from the jamb 16. On the jamb 16 using fasteners 15, the guide body 9 of the bolt 8 with the handle 13 and the hook 14 is rigidly fixed with the possibility of the latter passing through the groove 2 in the lining 1 after turning the lining 1 around the hinge 3 until it contacts the jamb 16 or the end face of the guide body 9. If there is a need to open the sash 5 with a limited opening clearance, the lining 1 is rotated around the hinge 3 until it comes into contact with the jamb 16 or the end face of the guide body 9. Then the bolt 8 by the handle 13 move along the guide body 9 until the hook 14 exits through the groove 2, while the handle 13 moves along the longitudinal well 11 until it leaves and enters the transverse well 10. Then, the handle 13 is moved along the transverse well 10 until it exits and enters the longitudinal well 12, while the bolt 8 rotates 90 degrees with the hook 14, which engages with the edges of the groove 2 and fixes the pad 1 from a possible rotation around the hinge 3, for example, when an attacker tries to reset the pad 1 sharply m slamming sash 5 with subsequent its abrupt opening. After that, open the locks on the leaf 5 (locks and an internal deadbolt, not shown) and open the leaf 5 to the length of the groove 2, while the lining 1 for the hook 14 through the slopes 7, interacting with the hook 14, gently pulls out a bit of the bolt 8 together with the handle 13, which, having moved into the longitudinal well 12, is reliably fixed from unauthorized rotation due to the interaction of the longitudinal protrusions 6 with the hook 14, which prevents the possibility of the bolt 8 turning and removing the hook 14 from the mesh with p odolnymi projections 6 on the strip 1, which ensures against unauthorized entry into the premises.

In the absence of slopes 7 of the longitudinal protrusions 6 (Fig. 15) after moving the handle 13 along the transverse well 10, it is necessary to move the handle 13 to the end along the longitudinal well 12, thereby fixing the handle 13 from unauthorized rotation and creating between the cover 1 and the ends of the hook 14 clearance equal to or slightly greater than the width of the longitudinal protrusions 6. After that, open the locks (not shown) on the sash 5 and turn it outward to the length of the groove 2.

To return the lining 1 to its original state, in which it is leaned against the sash 5, and the sash 5 can be fully opened, it is necessary to perform the above steps with the structural elements of the lumen limiter for opening the sash in the reverse sequence.

The use of the lumen limiter for opening the sash opening inward is carried out by performing the same sequence of actions as for the sash opening outward, with the difference that the lining 1 through the hinge 3 with the help of fasteners 4 is rigidly fixed to the jamb 16 with longitudinal projections 6 to the side, opposite to the sash 5, on which the guide body 9 with the bolt 8 is rigidly fastened with fasteners 15.

The sash opening clearance limiter can be widely used for doors of residential premises that can be opened both outside and inside, in order to prevent intruders from posing as law enforcement agencies, social and medical welfare institutions, post offices, house management companies, trade organizations and so on.

The sash opening limiter can also be widely used for office doors in cases where, for example, according to security rules, it is required to receive correspondence for signature without passing a courier or postman into the room.
