Description

The invention relates to hardware and can be used to protect the cylinder mechanism of locks in wooden and metal doors of buildings, apartments, safes, etc.

The castle is known according to RF patent No. 2174177, in which a U-shaped hardened plate mounted on the door is used to protect it, and which covers the entire castle body, thereby increasing its burglar resistance. However, at the same time, the secrecy mechanism remains available, which does not ensure its reliability.

Known overlay cylinder lock mechanism according to the patent of the Russian Federation No. 2098583, which has an external element that blocks access to the cylinder mechanism, and is located in the external high-strength element with the possibility of rotation of the protective washer made of high-strength material and having a hole for the key.

A disadvantage of the known device is its low resistance to criminal effects on the cylinder mechanism by knocking out the cylinder mechanism.

Known protective armor plate according to the patents of the Russian Federation 2283407 and 2283406. The protective armor plate for the cylinder mechanism of the lock contains an external high-strength element made in the form of a glass that blocks access to the cylinder mechanism. The glass is put on a protective case, which is also made of high-strength material. The glass can rotate around the housing and move relative to it in the longitudinal direction. The case is directly attached to the door and a cylinder lock mechanism is placed in it. An opening is made in the housing, in which a thrust sleeve made of high-strength material is placed with the possibility of longitudinal displacement. A protective washer made of steel and having a key hole is rotatably located in the bottom of the glass. The washer is located in the bottom of the glass with the possibility of longitudinal movement and its center of rotation does not coincide with the axis of rotation of the glass. This design protects the cylinder mechanism well, including from knocking out. However, the following problem arises.

Indeed, the standard length of the body of the cylinder locking mechanism and the armor plate is greater than the standard thickness of the door. Consequently, it is possible for a thief-burglar to act by grabbing the locking mechanism or lining with a tool and swinging until the cylinder locking mechanism can be torn out or broken by prying the lining. This is because the armored plate is attached to the inner surface of the door with screws screwed into the door from the inside of the room.

To prevent tearing of the cylinder mechanism of the lock, RF patent No. 2175373 provides a protective strip located on the inside of the door and which is connected from the inside by screws to the cylinder mechanism. This bar is adjacent to the door leaf and prevents tearing or turning of the cylinder mechanism. An example of such an armored lining is shown in figure 1. It is a round plate 1 with countersink holes 2 for mounting screws. In the center of the plate, a hole 3 is made for the cylinder mechanism. The current GOST of the Russian Federation for locks established that the distance between holes 2 should be 38 mm. In view of this, the overlay should be large, and given that the material from which the armor overlay is made is highly durable and difficult to process, while it itself is of high cost, the cost of its manufacture is unreasonably high. At the same time, the pads are located indoors and must meet high aesthetic requirements, i.e. they must be subjected to various types of processing and, for example, chrome plated. Also, despite the fact that the screw heads are recessed flush due to the countersink of holes 2, an attacker can still in advance know the location of the fixing screws in preparation, since they are visible, which can facilitate the task of further breaking the cylinder mechanism.

The technical result of the invention is the creation of a protective lining of the cylinder mechanism of the lock located inside the room and providing an increase in its burglar resistance while reducing costs and increasing aesthetic parameters.

The specified technical result is achieved in that the protective pad for the cylinder mechanism of the lock, containing a protective element adjacent to the door leaf and having holes for fasteners and a central hole for the cylinder mechanism, additionally has a plastic outlet with holes for fasteners and a decorative pad, with In this case, the socket and the overlay have each hole for the cylinder mechanism, the protective element is mounted on the socket, and the socket and the overlay have means for their connection.

The socket has a cavity in the form of a protective element, and the protective element is installed in this cavity.

The overlay is made cup-shaped, and the connection means are made in the form of an annular groove on the inner surface of the overlay and elastic hooks on the socket.

This embodiment of the protective lining can reduce the requirements for its appearance, reduce its material consumption, exclude its further processing and hide the heads of the fasteners.

The invention is illustrated by drawings, which depict

figure 1 is the closest analogue;

figure 2 - protective element according to the invention with a section aa;

figure 3 - plastic outlet with a cut BB;

figure 4 - decorative plate.

The protective pad for the cylinder mechanism of the lock contains a protective element 1, for example made of steel, adjacent to the door leaf from the inside of the room. In the presented embodiment, it is made by cross stamping or molding and does not require further processing. Due to this form, it has a reduced material consumption. In the protective element 1, holes 2 are made for fasteners (not shown), with which it is connected to the cylinder mechanism. The protective element 1 also has a central hole 3 for the cylinder mechanism. There is a socket 4 made of plastic, obtained by molding with holes 2 for fasteners and a central hole 3 for a cylinder mechanism. On the socket 4 there are elastic elements 5 with hooks 6, made in one piece with the socket during molding. A cavity 7 is made in the body of the outlet, repeating the shape of the protective element 1 and formed by the walls 8 on the outlet. The protective element 1 during assembly is located in this cavity. Moreover, all the corresponding holes 2 and 3 in the protective element and the socket of the pine. Decorative trim 9 also has a central hole 3 for the cylinder mechanism. The socket 4 and the pad 9 are connected by clicking the elastic elements 5 with hooks 6 in the annular groove 10, made on the inner surface of the pad. In this case, the pad is made bowl-shaped and hollow. The socket is placed in the cavity of the lining. The overlay can be made of plastic either by molding or by stamping and without additional processing to be applied to the product.

This protective pad can be used for any cylinder lock.

The protective pad is assembled as follows. A protective element 1 is installed in the socket 4 in its cavity 7 so that all the corresponding openings are pine. Through holes 2 are held screws. The protective element 1 is located on the side of the door leaf. Socket 4 is screwed to a cylinder mechanism or to an external armored plate. The lining is installed on the socket by snap-on 9. The snap-on is carried out by setting the hooks 6 of the elastic elements 5 into the groove 10 of the socket.

Cylinder mechanism installed.
