FIELD: locking devices, in particular, cylinder mechanisms that can be used in constructions of various locks, for example, door ones. SUBSTANCE: the lock cylinder mechanism has a cylindrical drum with a groove and rectangular fixing plates installed in it for movement and having rectangular holes for the key. The limit of the size of the plates equals the drum diameter. The plates are made eccentrically in the vertical relative to the center of the plates, and the holes for the key are arranged horizontally in the closed position of the lock. Each plate has its own eccentricity, and the key is wavy. The holes for the key are arranged eccentrically, both the upper and lower sides of the holes of each plate are positioned at different distances relative to the center of the plates in the vertical and made with chamfered edges. EFFECT: simplified construction, enhanced reliability in use and enhanced degree of secrecy of the lock cylinder mechanism. 5 dwg
