Abstract
A deadbolt lock mechanism for a door comprises a lock cylinder secured to a lock housing and having a movable locking tab connected thereto, a lock bolt slidably mounted within a channel in the housing, a disk rotatably mounted within the housing having a transverse pin extending therefrom, and a lever having an opening therein within which a portion of the transverse pin is disposed, the lever being pivotally mounted at one end to the housing and connected at the other end to the lock bolt. Upon rotation of the locking tab, the disk is rotated through actuation of the pin, and the lever is pivoted by the transverse pin engaging the sides of the opening within the lever to slide the lock bolt into an extended locked position or a retracted unlocked position, the lock bolt being deadlocked in position by the detent feature created by the geometrical relationship between the transverse pin and the sides of the opening within the lever.
