Known door lock in the description of the invention to patent No. 21194968, IPC EV 05/25, from 06/20/1997, publ. 07/10/1998, comprising a crossbar with a working stand located in the casing, a link movement mechanism and spring-loaded relative to the casing with the ability to move perpendicular to the crossbar movement, two-level levers and a double-bevel key. All the levers are made with raised slots, and the working deadbolt is made removable and with code recesses and longitudinal raised slots, while the lock has a removable mounting deadbolt and an installation key.

Disadvantages: low security against hacking and unauthorized tampering, for example, unauthorized tampering with master keys.

The closest known in its technical essence to the achieved result is the utility model selected as a prototype according to the patent of the Russian Federation No. 147112.

The disadvantage of this device is the low security against hacking and unauthorized tampering, for example, unauthorized tampering with master keys.

The aim of the proposed solution is to increase the protection class of the locking device from breaking and unauthorized opening by various methods and methods using pressure-relief devices (master keys).

The specified technical result is achieved due to the fact that the presented model of the locking device has a design feature - the presence of the main package of suvald (swinging type plates fixed and spring-loaded relative to the lock case) and a stacked rack structurally made as an additional package of suvald (plates fixed and spring-loaded with shank of the crossbar, performing translational plane-parallel motion), working simultaneously when interacting with each other. The main and additional suvald packages are set in motion simultaneously by turning the key having two barbs, with one key bar being positioned with the main suvald package, and the second with the additional suvald package, respectively.

Lever safe lock operates as follows.

A bolt (pos. 2) with a shank (pos. 3) and two code mechanisms are placed in the lock case (pos. 1) and two code mechanisms: a) the main package of the suvald (pos. 4). b) typesetting rack (additional package levers (pos. 8)). Both code mechanisms relative to the key well are located above and below, respectively, and are set in motion when the key is rotated simultaneously. The code mechanism (main package suvald) is driven by the beard A of the key, the code mechanism (additional package suvald) by the beard B of the key.

The main package of the suvald (pos. 4) is placed on the holding column (pos. 7), fixed to the lock case. The stand has protection against drilling. The levers are made in the form of swinging plates, spring-loaded with V-shaped springs (pos. 9) relative to the lock case. Structurally, the levers have code grooves (pos. 5A) corresponding to the code sizes (code slicing) of the beard A of the key and false grooves (pos. 13A). Code grooves (pos. 5A) and false grooves are positioned relative to the strut of the crossbar shank (pos. 12), which has a V-shape. The stand has protection against drilling. Also, the levers of the main package have code grooves (pos. 5B) and false grooves (pos. 13B), positioned relative to the stacking rack (additional package levers).

The typesetting stand (pos. 8) is made in the form of levers (plates) having V-shaped protrusions (pos. 11) corresponding to the code sizes (code cutting) of the key bar B. The levers of the typesetting stand are placed and held on the shank of the crossbar (pos. 3) using the shank racks (pos. 6), which have protection against drilling. The levers of the typesetting stand are spring-loaded with respect to the bolt shank with the help of springs (pos. 9). The key well structurally has a guide post (key 14) for entering the key into the keyhole.

When the double-wrench key inserted into the keyhole is turned clockwise, the lock code mechanisms are set in motion. If the code cutting of the key beard A coincides with the code of the code mechanism, the code grooves of the main package of the suvald should be installed on the same axis with the shank stand located on the shank of the crossbar. In this case, at the same time, the code protrusions of the stacking rack should correspond to the code of the code for cutting the beard B of the key, on the same axis as the code grooves (pos. 5B). If all codes match, the lock opens.

If the codes do not match, the lock is locked, both from the side of the crossbar and from the side of the typesetting rack. When manipulating and otherwise affecting the bolt and the code mechanisms, the lock also locks due to the design features of the security elements and the location of the code mechanisms.

The standard sizes of the codes of the main package of suvald and the typesetting rack are independent of each other and can vary both in size and in step. All sizes of security elements in the code mechanisms of the lock can also change.

The claimed combination of essential features is in direct causal relation to the achieved result.

Comparison of the claimed technical solution with the prototype made it possible to establish compliance with its criterion of "novelty", because it is not known from the prior art.

The proposed device is industrially applicable, because can be implemented by existing technical means.

Thus, the proposed technical solution meets the established conditions of patentability of a utility model.

The other known technical solutions for a similar purpose with similar significant features by the applicant was not found.

The utility model is illustrated by graphic material, where a level safe lock is shown in FIG.

Specification for FIG.: 1 - lock housing; 2 - crossbar; 3 - shank; 4 - the main package of suvald; 5A - code groove for the main package suvald; 5B - code groove for an additional package of suvald; 6 - a rack of a shaft for an additional package of level; 7 - rack for the main package suvald (guide for the shank); 8 - typesetting rack (additional package levers); 9 - suvald springs; 10 - keyhole; 11 - V-shaped protrusions stacked racks; 12 - a rack of a shaft for the main package of level; 13A - false grooves for the main package levers; 13B - false grooves for an additional package of levers; 14 - a directing rack for a double-wrench key; 15 - a double-wrench key; 16 - hole in the key for the guide rack; 17A - a beard of a key with a code for the main package suvald; 17B - a beard of a key with a code for an additional package suvald.

Thus, the application of the proposed technical solution has increased the protection class of the locking device from breaking and unauthorized opening by various methods and methods using pressure relief devices (master keys).
