Abstract
A motorized electronic lock is disclosed including an electric motor, a screw powered by the motor, a nut threadedly engaged with the screw and having two extending arms projecting therefrom, one of which arms is a cam follower arm that rides along a cam surface on a cam bracket, and the other of which is a locking arm that is engageable with a slot in a bolt in order to provide a dead-bolting feature for the bolt, and a relocking spring which is either held out of the way of the bolt by a downwardly extending leg of the cam bracket or is biased to a position behind the bolt, blocking the bolt from being able to retract.
