Abstract
A deadbolt door lock assembly operates a deadbolt between an unlocked and locked position. It generally comprises an actuator, a ring, and a biasing member. The ring contacts the actuator and rotates it in either a clockwise or counter-clockwise direction to lock the deadbolt. Once the deadbolt is locked, the biasing member urges the ring out of contact with the actuator. In one aspect, the assembly is operable in either the clockwise or counter-clockwise direction without disconnecting the biasing member. In another aspect, the biasing member includes different portions to urge the ring out of contact with the actuator depending on whether ring operation is in a clockwise or counter-clockwise direction. The assembly may include a backstop to indicate rotational direction of the ring to lock the deadbolt. The assembly may also include a stabilizing bridge to inhibit transverse rotation of mounting screws that secure the assembly to a door.
