Abstract

The present anti-shock mechanism for an electronic lock is designed to limit displacement of the solenoid plunger when an external force acts on the lock case of an electronic lock. An external force, such as that created by a translating actuator, applied in a horizontal direction parallel to the direction of plunger motion may cause the solenoid plunger to displace allowing the lock to be opened without authorization. The addition of a properly sized anti-shock mechanism limits displacement of the solenoid plunger due to an external force or impact and allows movement of the solenoid plunger when the solenoid plunger movement is due to an authorized access. Under normal operating conditions when the lock is locked, the bolt is in the fully extended position and the solenoid is not actuated. Upon authorization, the solenoid actuates causing the mechanical components to be placed in a condition whereby the operator may open the lock. When the lock is subjected to a force or impact, the anti-shock bellcrank moves or rotates to a position that will limit the plunger's movement and prevent the mechanical components of the lock from being placed in positions that would permit the lock to be opened.
