Abstract: A bolt assembly (21) including a movable bolt (34) and a user manipulatable bolt displacement assembly is disclosed. The bolt displacement assembly moves the bolt (34) between a locked and an unlocked position. The bolt displacement assembly includes a user manipulated handle (37), a torque transfer assembly (b 38) and an electromagnet (39). Handle (37) is mounted on an exterior side (36) of the bolt assembly (21) and is freely movable without coupling of the handle (37) to displace the bolt (34). Torque transfer assembly (38) in the form of a rocker arm (63) is mounted for movement in response to movement of the handle (37) and moves to and from a torque transmitting position during at least part of the movement cycle of the handle (37).

Abstract: A lock assembly (21) including a movable bolt (28), a movable handle (23) coupled to move the bolt (28) to an open position and a locking assembly (29) mounted for movement between a locked position securing the bolt (28) against movement and an unlocked position releasing the bolt (28) is disclosed. The locking assembly (29) moves in response to movement of the handle (23) and is normally supported in an unlocked position. Movement of the lock assembly (29) by the handle (23) results in moving to a locked position prior to movement of the bolt (28) to an opened position. An electromagnet (31) responsive to an input signal is provided to hold the locking means (29) in the unlocked position and to prevent movement of the locking means (29) to the locked position upon movement of the handle (23). This holding of the locking assembly (29) in the unlocked position permits opening of the bolt (28).

Abstract: An electronic digital combination lock including a frame supported within the interior of a door; a bolt mechanism which moves in relation to the frame to be retracted from a door jamb to open the door; a logic circuit which generates a control signal in response to entry of a predetermined combination signal, including push button switches which are housed within the door interior and produce bits when selectively depressed; and, a rotatable handle member which is coupled to the frame from the outside surface of the door to activate the bolt mechanism, including a tube that is coupled adjacent the push button switches and is selectively rotatable to depress each of the switches to generate the predetermined combination signal. The handle member including the tube has only limited rotational movement until the correct combination signal is entered, at which time an electromagnetic and lever mechanism is energized to release the handle member for extended rotation to retract the bolt mechanism.
