<p>An anti-shock arrangement for a solenoid blocking device of a lock, where the blocking device includes an electromagnetic coil, a stator, and an armature adapted to perform a first motion relative to the stator under the magnetic action of the coil. The anti-shock arrangement comprises a first element mounted to the armature and a second element fixed to the stator. The first element is engaged to the second element so as to perform a second motion when the armature performs the first motion. The second motion is associated with overcoming a predetermined friction force, thereby preventing the two motions under shock applied on the whole device in direction of the first motion but allowing the first motion under the magnetic action of the coil.</p> |
