Abstract (en)
[origin: US4807455A] The latch bolt of a lock is prevented from fully retracting when an electromagnet is unenergized so that a blocking lever carrying the armature can pivot about a pivot point displaced from the armature and a slide or lever pivotally linked to the blocking lever places a blocking nose; when the electromagnet is energized the blocking lever pivots on the armature and thereby moves the slide or lever out of the track of that pin. The armature is normally held against the electromagnet by a spring so that very little electric power is needed and only in case of a desired lock release.
