METHOD OF MUTUAL CONTROL AND DECODING OF TWO CYLINDER LOCK, AND LOCK WITH CONTROLLED DUAL CYLINDER Russian patent published in 2018 - IPC E05B63/14 

FIELD: locks; information technology.

SUBSTANCE: method of mutual decoding and control of cylinders of a two-cylinder lock, which includes first decoding the code of first cylinder (111, 24, 322, 52) of the lock, in which, before decoding the code of the first cylinder of the lock, first cylinder (111, 24, 322, 52) of the lock limits the decoding of the code combination of second cylinder (121, 23, 321, 53) of the lock, after decoding the code of first cylinder (111, 24, 322, 52) of the lock, the second cylinder of lock (121, 23, 321, 53) limits the rotation of the first cylinder of the lock; first cylinder of cylinder (111, 24, 322, 52) of the lock can move from the first position to the second position, using the predetermined difference of these positions, but cannot rotate; when first cylinder (111, 24, 322, 52) of the lock moves to the second position, the restriction on decoding second cylinder (121, 23, 321, 53) of the lock is removed, second cylinder (121, 23, 321, 53) of the lock still restricts the rotation of first cylinder (111, 24, 322, 52) of the lock, and when decoding of the code of second cylinder (121, 23, 321, 53) of the lock is performed, the first cylinder of lock (111, 24, 322, 52) and second cylinder (121, 23, 321, 53) of the lock can rotate together and thus providing unlocking of the lock.

EFFECT: present invention also concerns the reciprocal control of a cylinder of a two-cylinder lock.
