LOCK Russian patent published in 2012 - IPC E05B27/00 

FIELD: construction.

SUBSTANCE: lock comprises a body with a cover, a mechanism of bolt displacement and a socket wrench. In the body there are axial holes for freely moving locking pins. Locking pins are made from more than two split parts. One of these parts is arranged in the form of a stepped shaft, the other ones - from cylinders. The mechanism of bolt displacement interacts with locking pins. The socket wrench is arranged with holes located coaxially with axes of locking pins. In the holes of the socket wrench there are stops arranged as fixed in the code position. The lock is also equipped with an autonomous secret block, in which locking pins are installed. The secret block when locking the bolt is rigidly fixed in the body, and in the unlocked position it is extracted, opening access to the bolt or the mechanism of its displacement.

EFFECT: improved security properties of a lock.
