Electronic lock system
First Claim
1. An electronic lock system, which is also manually operable, for rotating a lock cylinder to move a lock mechanism which includes at least one bolt, the lock cylinder being mechanically coupled to the at least one bolt such that rotation of the lock cylinder causes displacement of the at least one bolt, the system comprising:
- (a) a bidirectional motor having a central axle mechanically engagable with the lock cylinder in a driving relation having a drive ratio of not more than about 2;
1; and
(b) a manually operable handle mechanically linked in driving relation with said central axle to allow manual rotation of said central axle without activation of said motor.

Abstract
An electronic lock system which is also manually operable is provided for driving a lock cylinder to move a lock mechanism which includes at least one bolt. The lock system includes a bidirectional motor having a central axle mechanically engagable with the lock cylinder in a driving relation having a drive ratio of not more than about 2:1, and preferably of 1:1. A manually operable handle is mechanically linked in driving relation with the central axle to allow manual rotation of the central axle without activation of the motor.
