Description

The invention relates to the field of locking devices, in particular to door, safe and other locks that require special keys for their unlocking, and can be used to lock the doors of apartments and other objects.

A well-known door lock containing a housing with a lid, cylinder lock mechanisms located in the housing with a leash for moving the bolt (RF patent for the invention No. 1789004, E05B 35/12, 10/13/1989). The disadvantage of this lock is the ease of opening it due to cylinder mechanisms of constipation, followed by unlocking the lock.

Known locking device with a wedge mechanism for the interaction of the key with the circuit elements, comprising a housing, a cylinder with a leash housed in it, spring-loaded pins that force-lock the mechanism. The key has wedge sockets of various sizes. The dimensions of the pins are selected so that when they enter the key slots, they align the spring-loaded contactors interacting with them. The disadvantage of this device is its low secrecy (I.I. Artobolevsky, Volume 3. Mechanisms in modern technology. M: Nauka, 1979, p. 342).

The closest technical solution adopted for the prototype is a disk cylinder lock and a key for this lock, containing a cylindrical body, an inner cylinder with a set of disks, which include locking disks with recesses for the locking pin located on their periphery and a key hole in the center, as well as a leash for interacting with the bolt, a guide element located in the key channel, a set of intermediate disks with a key hole and recesses on the periphery, locking disks are mounted with the possibility of rotation and under the action of the key to open the lock position.

The inner cylinder is closed with the housing by means of a spring-loaded bar placed partially in the housing, partially in the cylinder (RF patent No. 2121515, E05B 29/08, 1994). Its disadvantage is the high structural complexity.

The task to which the invention is directed is to increase the secrecy and reliability of locking the lock, as well as simplifying the design.

The solution to this problem is achieved by the fact that the locking device, mainly to door and safe locks, contains a key, a housing with a set of discs of security located in it with key openings and grooves on the periphery.

The difference between the proposed locking device and adopted for the prototype is that it is equipped with a movable and fixed covers that cover the housing on both sides, while the fixed cover is rigidly connected to the housing, and the movable is mounted to rotate inside the housing, the Central axis, one end is rigidly fixed in the hub of the fixed cover, and the other installed in the movable cover with the possibility of its rotation on the central axis, a contactor including the axle box and fixed on it with the possibility of rotation The lever with hooks, on the outer surface of the axle box there is a groove and segmental selection, in which the aforementioned one-arm lever is mounted and spring-loaded for engagement by means of hooks with grooves on the security discs and axle box, while the axle box is rotatably mounted on the hub of the fixed cover and cover discs of secrecy with an inner surface, a sleeve with a secret protrusion, movably mounted on the central axis and rigidly connected with the movable cover, secretory samples made in movable size whelping to the hub and covering discs secrecy sectorial protrusion, the wheels and the sleeve are interconnected elastic member, and the hub interface shelves and disc shaped grooves are made, which form the shed turnkey; the hooks are hook-shaped, with at least one of the hooks made in the form of a rotating roller; in addition, the locking device, for example, for door locks of residential and office premises, can be equipped with a mechanism for internal opening, made in the form of a gear transmission mounted on a fixed cover connected with a handle and a contact; on the axle box there is a leash for interaction with the bolt, and the key hole is made in the movable cover.

Figure 1 shows a view of the locking device from the side of the keyhole; figure 2 is a section along aa in figure 1; figure 3 is a section along BB in figure 2 in the "open" position without a key; figure 4 is a section along G-D in figure 2 in the "closed" position with a key; figure 5 is a section along the EE in the closed position without a key with the image of the hook in the form of a roller; in Fig.6 is a section along FJ in Fig.4; Fig.7 is a view along arrow D in Fig.4 (private breakout); on Fig - view of the spring-loaded two-arm lever; Fig.9 is a section along bb in Fig.8.

The locking device includes a code mechanism 1 for moving the bolt (the bolt is not shown in the drawing) and an internal mechanism for moving the bolt 2. The device can be mounted on the doors of residential and other premises, then the option with the mechanism of internal movement of the 2 deadbolt or in the safe version without it is used.

The code mechanism 1 comprises a housing 3, a fixed 4 and a movable 5 cover, covering the housing 3 from two sides. The cover 4 is attached to the housing 3 rigidly. The central axis 6 is rigidly fixed at one end in the cover 4, and the other in the cover 5 with the possibility of rotation of the cover 5 on the axis 6. On the axis 6 is mounted movable sleeve 7 with a sector ledge 8, rigidly connected with the cover 5. On the sleeve 7 are installed with the possibility turning several discs of secrecy 9, 10, 11, 12 and 13 with sector samples 14, covering a sector ledge 8 and through elastic elements 15 is connected with the said disks 9-13. On the mating side of the disks and the protrusion in the shelf 16 of the disks 9-13 and the shelf 17 of the protrusion 8 there are made shaped grooves 18 and 18a, forming a turnkey pharynx 20. On the hub 21 of the cover 4, a closure 22 with a leash 23 for engaging with the bolt (not shown in the drawing, it can be included in any embodiment of the lock) and includes a axle box 22a with a stepped hole and a one-arm lever 23. On the outer surface of the axle box 22a, a segmental selection 24 is made, in which a lever 23 spring-loaded with an elastic element is mounted on the axis 2526. The lever 23 at the free end is provided with hooks 28 having a hook shape, and at least one of the hooks 28 is made in the form of a rotating roller 29. In the disks along their periphery, grooves 30 are made, and in the axle box 22a, a groove 31 for interacting with the hooks 28. Jaw 19 turnkey 20 is offset relative to the axis 32 of the locking device. A keyhole 33 and an additional hole 34 for the L-shaped process 20a of the key 20 are made in the cover 5, on the shaft of which there are stepped protrusions 35 and depressions 36 of various heights and depths that determine the rotation of the disks in the open-closed positions. The mechanism for internal opening and closing 2 includes a gear 37, freely mounted on the hub 21 and rigidly connected to the contactor 22, the gear 38, mounted on the axis 39 with the handle 40.

The locking device operates as follows. In the assembled form, the sleeve 7 freely rotates on the axis 6, and the discs of secrecy 9-13 freely rotate on the cylindrical surface of the sleeve 7, so each of the discs 9-13 can be rotated relative to each other at a certain angle, and, accordingly, the grooves 30 and 31. The lock is in the closed position. The key 20 is inserted into the keyhole 33, the disks 9, 10, 11, 12 and 13 under the action of the protrusions 35 of the key are rotated so that the grooves 30 are installed on the same line. Then, when the key 20 is brought to a stop and the L-shaped process has entered the hole 34, by turning the key 20 we rotate the sleeve 7 together with the disks 9-13, achieving alignment of the grooves 30 and 31 in one line. Only when the grooves 30 and 31 are installed in one line, the lever 23 with the hooks 28 under the action of the elastic element 26 will turn and the hooks 28 will enter the grooves 30 and 31, the circuit will be closed key 20 - disks 9-13 - contactor 22, turning the key, turn the contactor 22 and through the leash 23 we move the bolt (shown in the drawing). After opening or closing the lock with the indicated actions, we remove the key 20, while the protrusions 35, acting on the disks 9-13, rotate them, disengaging the hook 28, and the disks 9-13 under the action of the elastic elements 15 diverge randomly at different angles. The cover 5 also rotates, which does not allow to determine whether the lock is open or closed.

The proposed design of the locking device provides high security locking and significantly reduces the likelihood of opening with a master key, much easier to manufacture, which reduces its cost.

The number of options for the execution of the pharynx configuration is almost unlimited, you can additionally change the number of disks, thereby increasing the number of privacy options.
