RU2624340C1 - Method for protecting the locks from unauthorised access - Google Patents

Abstract

FIELD: construction.

SUBSTANCE: front part of the remaining keys is equally cut off and inserted into the lock cylinder until it stops. As a result, the lost (stolen) key loses its functions, and all the fragmented keys work as usual, thus eliminating the need to replace the lock or use expensive programmable locks.

EFFECT: increasing the reliability.

Description

The invention relates to the field of application of methods for protecting locks against unauthorized access and opening in case of loss or theft of a key.

There are various ways to protect locks from unauthorized access and their opening, however, in case of loss of the key or its theft, the problem arises of an urgent replacement of the lock or at least a larva, which cannot always be executed promptly.

There are various designs of door locks, the complexity and reliability of the design of which dramatically reduces the risk of unauthorized breaking and opening them by selecting various keys and master keys. For example, in patent RU 2279518 IPC E05B 17/14, a keyhole is locked using a magnetic key and an associated gate valve that blocks the well bore.

Another patent - RU 2184197 IPC E05B 27/00 - proposes the construction of a programmable cylindrical lock containing a stator, in which there is a hole inserted into the rotor stator hole, in which there is a key hole, a programming mechanism that allows the lock to be reprogrammed during the replacement operation to work with a different key, different from the key that was previously used to work with the lock, and at least one locking pin or counter-pin, which is divided into at least two parts and can move I'm in an open position by at least two keys of different shapes. The programming mechanism contains in the stator at least one longitudinal groove made in the hole, optionally a group of stator sockets and locking counter-pins and springs located in them, and in the rotor contains a group of first sockets that intersect the key hole, and a group of second sockets parallel first nests. This lock has increased ease of use and if you lose or steal a key, you can quickly reprogram the lock and switch to new keys, thereby eliminating the possibility of unauthorized use of the lost (stolen) key.

However, this castle is very complex and therefore has a high cost. For example, a CISA 17685.48.0 re-programmable door lock costs 18,700 rubles ( cisa.trascon.ru ).

The technical result consists in exceptional simplicity and does not require the acquisition of any new keys. It retains the ability to use spare keys, while blocking the opening of the lock with a lost (stolen) key.

The technical result is achieved by the fact that instead of complex improvements of the lock, a fragment is separated from the key and inserted completely into the larva, which allows you to open the lock with the remaining fragment and excludes the possibility of opening it with a lost (stolen) key.

Thus, the remaining main section of the key, when inserted into the larva, forms a complete key, and you can open the lock with it. Similarly, all spare keys for family or team members can be prepared. At the same time, the use of the stolen key will not give results, since its movement inside the larva will be blocked by the fragment installed in it.

The method can be used not only for door locks, but also for other types of locks in which a key fragmented by the above method can be used, for example, in padlocks, padlocks and barn locks, as well as in cars (door locks and ignition key), etc. .

Claims (1)

A way to protect the lock from unauthorized access in case of loss or theft of the key, characterized in that a fragment is separated from the key and inserted into the larva until it stops, which allows you to open the lock with the remaining part of the key and excludes the possibility of opening it with the original (lost or stolen) key.
