ABSTRACT:
A self-powered electric lock includes a lock bolt and a first engagement element having disengaged and engageable positions. An electric actuator includes an output operative to move the first engagement element to its engageable position. A manually operated rotatable member is operatively coupled to the first engagement element when the first engagement element is in its engageable position. A lock bolt drive mechanism is coupled to the lock bolt and to the first engagement element when the first engagement element is in its engageable position. The movable output moves the first engagement element to its engageable position upon input of correct electronic data. An electricity generator is coupled to the manually operated rotatable member. The electricity powers the electric actuator and an electronic data input device. The manually operated rotatable member is also used to actuate the lock bolt drive mechanism and retract the lock bolt.
