Abstract
A door lock assembly operates a deadbolt between unlocked and locked positions. It includes an actuator, a ring, and a spring member. The actuator includes an integral arm, that extends inwardly, to the center of the ring, and the arm has a cam provided upon the center axis, and receives the torque blade from center key cylinder. In the preferred embodiment, when the ring is turned in a clockwise direction, it locks the deadbolt of the latch bolt assembly, by shifting it to a locking position, and all of this can be achieved because the key cylinder is on a center axis, and the axis of the latch bolt assembly and deadbolt intersects that same center axis in their operation.
