LOCK Russian patent published in 1997 - IPC

FIELD: locking devices. SUBSTANCE: lock has key and lock mechanism which consists of body and core movably installed in it. Core is engageable with key working part. Key working part has key code in form of coordinates of code surfaces and/or coordinates of permanent magnets. Body accommodates switch for charging modes of lock operation, control shells and rods. Control shells are installed movably and kinematically interconnected. Control shells have code grooves consisting of rectilinear slots and connecting sections. Spring-loaded rods are installed for straight line motion. They are engageable with code grooves through pins secured to them which are located in rectilinear slots of code grooves. Rods are engageable with key working part with the aid of feelers or permanent magnets attached to them. Core is kinematically connected through control shell with movable member which connects lock mechanism with actuating mechanism. Key code is equivalent to lock code which equals coordinates of intersection of axial lines of rectilinear slots and beginnings of connecting sections. EFFECT: higher efficiency. 41 dwg, 2 tbl
