ABSTRACT:
A mechanical device such as a lock with anti-shock arrangement, comprising a locking member adapted for linear motion. The anti-shock arrangement comprises a balancing member mounted for linear motion substantially parallel to the locking member motion and a pivotally supported lever with two ends and a pivoting axis therebetween. The locking member abuts one of the ends and the balancing member abuts the other end, the abutment being maintained by a biasing means such as a spring. The lever has substantially zero moment of inertia with respect to its pivoting axis. The locking member, for example an armature of a bi-stable solenoid, is held in a blocked position of the device by a permanent magnet. Upon a shock applied to the device, the locking member and the balancing member create inertial forces substantially balancing each other, while vibration forces are cancelled by the abutment arrangement and the permanent magnet.
