CODED PROGRAMMABLE LOCK Russian patent published in 1995 - IPC

FIELD: security facilities. SUBSTANCE: coded programmable lock has a casing, in which a code drum is installed for fixed step rotation in the "working" and "false" directions; the drum accommodates a longitudinal movable cross-bar that is hinge-joined to the locking member. To fix the step at rotation, the code drum is kinematically linked with a catch through a toothed bead. The code drum has grooves on flanges, which receive movable code members engageable with clincher-shaped pushers on the casing cover on one side, and kinematically linked through cranks with spring-loaded pushers on the other side. Installed perpendicularly to the drum on the casing is a handle, which through a cam plate is kinematically linked with the catch and locking member. EFFECT: enhanced security. 4 cl, 8 dwg
