Solenoid controlled bolt control for an electronic lock

摘要

An electronic combination lock (10) of the self-powered type, wherein the electrical energy for operation of the lock is developed within the lock itself, has a solenoid (40) and armature (42) which moves a latch (32) to allow downward movement of a slide (28) and so the withdrawal of bolt (14) through bolt lever (16) and cam (26). The solenoid (40) and armature (42) magnetically seal in the activated position, thus preserving the "open" condition of the lock (10) until such time as the operator may withdraw the bolt (14) at which time a cam surface (36) of the slide (28) engages a cam follower (34) to move a reset lever (34) to unseal the solenoid (40) and allow the latch (32) to move back to its latched position.
