CODED MAGNETOMECHANICAL LOCK Russian patent published in 1998 - IPC

FIELD: locking devices. SUBSTANCE: coded magnetomechanical lock is protected from opening by skeleton keys. It is adapted to resetting of code. Lock has secrecy mechanism with body. Circular bore and slot are made in body for inserting key. Installed in body is turnable holder with blind holes. Installed in holder is matrix with inserts. Also provided is end-face key with orienting magnets. End-face key has kinematic connection with end-face of holder. There is also locking member. Holder of secrecy mechanism is spring-biased and is longitudinally movable. Magneto-sensitive interlocking members are made in the form of balls. These interlocking members are installed in cylindrical spaces which are created by bases of blind holes in holder and by end-faces of inserts in matrix. At least one of aforesaid cylindrical spaces is eccentric. Holder of end-face key with orienting magnets is spring-biased and can turn autonomously. EFFECT: higher efficiency. 3 dwg
