ABSTRACT:
An electrically operated door lock has a pair of pivotally mounted jaws (12, 13) which can be moved towards and away from each other to capture and release the end of a bolt or style (11). The bolt or style moves in a direction perpendicular to the direction of movement of the jaws. The jaws are locked in the captive position by a cam (39) which is controlled by a low power electric motor (81). The motor has three positions corresponding to release, locking and deadlocking of the jaws, the jaws being releasable by a handle (49) in the locked position but not when deadlocked. An electronic control system is used to control the motor, and the lock can be released using an electronic coded proximity key.
