CODED LOCK Russian patent published in 1998 - IPC

FIELD: mechanical engineering; locking devices. SUBSTANCE: coded lock has cylindrical body, and installed in body are turnable coding disks, sleeve with annular bore adapted for interaction with coding disks, and lockable member of cylindrical configuration having splittable joint with body. Lockable member and sleeve are conjugated with body along parallel cylindrical surfaces. Coding disks are installed with possible access to them from side which is closed by sleeve. Sleeve has slots which are open to annular bore and directed to open end of sleeve. There is hole for setting code with possibility of successive positioning of this hole against each coding disk. Radial protrusions in body can interact with annular bore and slots. There is detent for joining body with lockable member. Detent is operated in disassembling by at least longitudinal displacement of body in direction away from closed end of sleeve. Value of required longitudinal displacement of body is selected to be larger than clearance between sleeve and lockable member. EFFECT: high efficiency. 4 cl, 10 dwg
