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 with the closed leaf into engagement with the edges of the groove in order to provide a limited angle of rotation of the leaf and withdraw the spherical or mushroom-shaped thickening of the hook in the closed leaf from the mesh with the edges of the groove to ensure that the leaf opens completely [5], [6].

This known device has the following three technical disadvantages. Firstly, it can only be used for shutters that open inside the room, since the locking 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-bolt, locking recesses for additional (second degree) fixing the T-bolt in the locked position and a pusher with a spring [7].

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 (for example, postmen or couriers) delivered small-sized items or parcels.

A device for limiting the angle of rotation of the sash, called the "chain loop". This hinge chain contains an overlay with a hinge made in the form of an elongated hinge with a groove extending at the end facing the hinge (in fact, this is a locking plate that performs the same functions as in the above-described “door chain” device, but fixed not rigidly, but articulated, 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 hooking on the lining 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, and the spherical or mushroom-shaped thickening stands for sash edge. 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) [8].

The technical disadvantage of this device is that the hook acts as a spherical or mushroom-shaped thickening over the edge of the sash, 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 into the lumen of the door frame, which not only has an unaesthetic appearance, but also reduces the width of the door frame passage, as well as 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 closest adopted for the prototype is a device for limiting the angle of rotation of the sash, containing a hook and hinged plate with a longitudinal groove having an extended end facing the hinge, the hook is made on the end of the bolt with the possibility of longitudinal movement and passage through the extended the end of the longitudinal groove of the lining, and also with the possibility of engagement for at least one edge of the longitudinal groove along its entire length when the sash is opened. To solve the problem of ensuring manufacturability, including the possibility of using a deadbolt of both square and round cross-section, the hook is made at the end of the deadbolt, on which the handle is rigidly fixed, the deadbolt with the possibility of longitudinal movement is placed in the guide body, in which the longitudinal well is made with the possibility of movement along the handle of the bolt, the pad is made in the form of a plate, and the hinge is made in the form of a door or window hinge [9].

The disadvantage of the prototype is that an attacker using a small mount or a thick screwdriver can expand the groove in the middle part of the cover so that the hook disengages from the longitudinal edges of the longitudinal groove of the cover, which ensures unhindered entry into the room. This reduces the safety of operation of the prototype. To reduce or eliminate this drawback in the prototype, it is necessary either to make the overlay wider and thicker, or to carry out the hooks wider, or to perform both at the same time, which in any of these cases leads to an increase in the dimensions and mass (material consumption) of the prototype.

The objective of the invention is to create a new patentable limiter of the angle of rotation of the sash, not having the above disadvantages of the prototype and analogues and, accordingly, ensuring the achievement of the following technical results in comparison with the prototype, namely:

- improving the reliability of operation of the device to limit the angle of rotation of the sash;

- improving the safety of operation of the device to limit the angle of rotation of the sash;

- reducing the dimensions and mass (material consumption) of the device to limit the angle of rotation of the sash;

- ensuring the manufacturability of manufacturing by using parts that are simple in shape, each of which has a high manufacturability;

- ensuring the simplicity of the design due to both the simplicity of the shapes of each part and the simplicity of their connection with each other.

In addition, the object of the invention is to expand the arsenal of technical means of a similar purpose.

The objectives of the invention are solved, and technical results are achieved by the fact that in the device for limiting the angle of rotation of the sash (option 3), comprising a hinged plate with a longitudinal groove having an expanded end facing the hinge and a hook made movable with the possibility of longitudinal movement and passing through the widened end of the groove with subsequent engagement at least one edge of the longitudinal groove along its entire length when the sash is opened, while the slip with the possibility of moving along it is worn with a 0-shaped (in cross-section) slider, and in both walls of the 0-shaped slider is made through the hole with the possibility of passing the hook through these holes and through the extended end of the longitudinal groove when it is placed between these holes.

To ensure manufacturability, the 0-shaped slider is made of a plate, the material of which can be either metal or non-metal.

New features of the invention, together with known features, allow to solve the problems of the invention and achieve the above technical results, while all these signs form an inextricable combination, due to which the first of the above objectives of the invention is solved and the above technical results are achieved.

For example, increasing the safety of operation and reducing the dimensions, which entails a decrease in the mass (material consumption) of the device for limiting the angle of rotation of the sash (option 3), is ensured by the fact that the slip with the possibility of moving along it is worn with a 0-shaped slider, and in both walls it is the slider is made through the hole with the possibility of passage of the hook through these holes and through the extended end of the longitudinal groove when it is placed between these holes. Indeed, the 0-shaped slider, as a separate part, with small dimensions and small wall thickness is able to withstand huge loads until it collapses, especially if it is made of steel. And since the 0-shaped slider with the ajar sash is inextricably connected to the hook (in fact, the 0-shaped slider is put on the bolt with a hook in this case), the longitudinal groove cannot be expanded at the location of the hook until the 0-shaped slider it will not be destroyed (torn), which requires extremely great efforts, especially taking into account the presence of two walls in the 0-shaped slider, and not one, which is guaranteed to increase the reliability, and with it the operational safety of the device, to limit the leaf rotation angle (in Rianta 3) in terms of its weight and size in accordance with the prior art. Therefore, when a 0-shaped slider with the above characteristics is placed on the cover plate, the cover and hook can be made with smaller overall dimensions (for example, the cover can be made narrower and thinner and the hook is smaller) than in the absence of a 0-shaped slider, while the reliability and safety of operation will not only not be reduced by reducing the dimensions and mass of the device to limit the angle of rotation of the sash (option 3) compared with the prototype, but an increase in these character can be achieved Istik.

It should be noted that the device for limiting the angle of rotation of the sash (option 3), as well as the prototype, can be used both for the sash opening outward and for the sash opening inward.

A device for limiting the angle of rotation of the sash (option 3), being new, expands the arsenal of technical equipment for a similar purpose, which is additionally one of the objectives of the invention.

Thus, these objectives of the invention are solved and all these technical results can be achieved by a combination of known and new features of the invention.

A non-limiting embodiment of the present invention is described with reference to the drawings by way of example.

In FIG. 1 shows a perspective view of a device for limiting the angle of rotation of the leaf (option 3) in the initial state, in which the pad with the 0-shaped slider is leaned against the leaf opening outward.

In FIG. 2 shows the same as in FIG. 1, but with the bolt hook extended outward (beyond the edge of the joint).

In FIG. 3 shows the same as in FIG. 2, but in the slightly open position of the sash to the length of the longitudinal groove in the cover plate to prevent unauthorized passage due to the reliable engagement of the hook on both longitudinal edges of the longitudinal groove, the hook is equipped with a 0-shaped slider that prevents the attacker from sliding the longitudinal groove in order to remove the hook from the mesh with the longitudinal edges of the longitudinal groove.

In FIG. 4 shows a rectangular projection with the position of the lining, turned until the 0-shaped slider touches the jamb, the left view (in relation to the sash, if facing it), is enlarged.

In FIG. 5 shows the same as in FIG. 4, front view, enlarged.

In FIG. 6 shows the same as in FIG. 4, top view, enlarged.

In FIG. 7 shows a section along AA in FIG. 6, rotated, enlarged.

In FIG. 8 as in FIG. 6 is a top view, but with the bolt hook extended outward through the holes in the 0-shaped slider and through the widened end of the longitudinal groove in the patch, is enlarged.

In FIG. 9 shows a section BB in FIG. 8, rotated, enlarged.

In FIG. 10 depicts the same as in FIG. 3, top view, enlarged.

In FIG. 11 shows a cross-section along BB in FIG. 10, rotated, enlarged.

A device for limiting the angle of rotation of the sash (option 3) contains a cover 1 made of a steel plate, with a longitudinal groove 2 of the same width along its entire length, ending with an extended end 3, facing the hinge 4, which is made with the possibility of rotation of the cover 1 in the form the door hinge and is rigidly fixed with fasteners 5 on the sash 6, which opens outward. The device also contains a steel (in this example) bolt 7 with a rectangular cross-section (in this example), placed in a guide body 8 with a rectangular cross-section (in this example) with the possibility of longitudinal movement. A longitudinal well 9 is made in the guiding body 8 with the possibility of moving along it a handle 10, rigidly fixed on the deadbolt 7, at one end of which a hook 11 is made with the possibility of its both edges 12 and 13 being hooked to both longitudinal edges of the longitudinal groove 2. Edges 12 and 13 the hooks 11 are formed (in this example) by making transverse grooves 14 and 15 in the deadbolt 7; the guiding body 8 is fixedly fastened to the jamb with the help of fasteners 16. The 0-shaped slider 18 is put on the lining 1 with the possibility of moving along it (slider called 0-shaped, as in cross section it has a shape resembling an elongated number 0) made of a steel plate (in this example). In both walls of the 0-shaped slider 18, one hole 19 and 20 is made with the possibility of the hook 11 passing through the holes 19, 20 and through the extended end of the longitudinal groove 2 when it is placed between the holes 19 and 20, as well as with the possibility of subsequent engagement of the hook 11 for both longitudinal edges of the longitudinal groove 2 in the lining 1 with a limited rotation of the sash 6.

A device for limiting the angle of rotation of the sash (option 3), opening outward, is used as follows.

The hinge 6, made in the form of a door hinge, is rigidly attached to the sash 6 using fasteners 5 (screws or screws). A pivot 1 with a longitudinal groove 2 having an expanded end 3 facing the hinge mount 4 is rotatably mounted on a hinge mount 4. A guide body 8 is fixedly fastened to the jamb 17 by means of fasteners 16, inside of which there is a dead bolt 7 with a handle 10 and a hook 11, with the possibility of the hook 11 passing through the holes 19, 20 and through the widened end of the longitudinal groove 2 when it is placed between the holes 19 and 20 after turning the lining 1 around the hinge 4 until the 0-shaped slider comes into contact with 18 s the jamb 17 or the end face of the guide body 8, while the holes 19 and 20 in the 0-shaped slider 18 and the extended end 3 of the longitudinal groove 2 should be located opposite the hook 11 (Fig. 1 and 2). If it becomes necessary to open the sash 6 with a limited angle of rotation, the cover 1 is rotated around the hinge 4 until the 0-shaped slider 18 contacts the jamb 17 or the end of the guide body 8 and the holes 19 and 20 are placed in the 0-shaped slider 18 and the extended end 3 the longitudinal groove 2 in the pad 1 opposite the hook 11 (Fig. 4-7, 14). Then, the bolt 7 by the handle 10 is moved all the way along the longitudinal well 9 in the guide body 8 until the hook 11 exits, while the hook 11 passes through the holes 19 and 20 in the 0-shaped slider 18 and through the extended end 3 of the longitudinal groove 2 located between them in the pad 1 (Fig. 8, 9). After that, the locks on the leaf 6 are opened (locks and internal bolt, not shown in the drawings) and the leaf 6 is opened within the length of the longitudinal groove 2 (Fig. 3, 10, 11), while the longitudinal edges of the longitudinal groove 2 enter the transverse grooves 14 and 15 of the bolt 7 and engage with the edges 12 and 13 of the hook 11, so that the lining 1 is securely fixed from unauthorized rotation, which guarantees against unauthorized entry into the room.

To return the lining 1 to its original state, in which it is leaned against the sash 6, and the sash 6 can be fully opened, it is necessary to perform the above steps with the structural elements of the device to limit the angle of rotation of the sash (option 3) in the reverse sequence.

The use of the device to limit the angle of rotation of the sash (option 3), opening inward, is carried out by performing the same sequence of actions as for the sash opening outward, with the difference that the cover 1 with a longitudinal groove 2 and a 0-shaped slider 18 through a hinge 4 using fasteners 5 attached to the jamb 17, and on the sash 6 is rigidly fastened using fasteners 16 guide body 8, which houses the bolt 7 with the handle 10 and the hook 11.

The device for limiting the angle of rotation of the sash (option 3) can be widely used for doors of residential premises, opening both outside and inside, in order to prevent intruders from posing as law enforcement agencies, social and medical welfare institutions, post offices , home management companies, trade organizations and so on.

The device for limiting the angle of rotation of the sash (option 3) can also be widely used for office doors in cases where, for example, according to security rules, it is required to receive correspondence for painting without passing the courier or postman into the room.
