CODE LOCK MECHANISM Russian patent published in 2007 - IPC E05B37/08 

FIELD: locks, in particular, code mechanisms of mechanical locks, meant for locking doors of living and working spaces.

SUBSTANCE: code lock mechanism contains case, shaft mounted in the case, code element rigidly connected to shaft, key and sensitive element, mounted with possible interaction with code element. Shaft is made with possible axial movement and is spring-loaded in axial direction, and key - in form of a barrel with central rod mounted on it with possible rotation and axial movement, on which first circular element is mounted having profiled end surface interacting with console end of cam, other end of which is fastened to side wall of barrel, equipped with means for locking its position relatively to the case. Central rod by means of collapsible connection is connected to shaft end exiting dimensions of case with locking of angular position of central rod relatively to the shaft, while the code element is made in form of second circular element rigidly mounted on the shaft, end surface of which repeats the shape of profile of end surface of first circular element, while the sensitive element is mounted with possible interaction with end profiled surface of second circular element.

EFFECT: increased vandalism resistance and secrecy with simultaneously simplified design and increased comfort of lock operation.
