Patent ID: 7748244

Claim:
A lock assembly for use with a bolt movable from a retracted position to an extended position, the lock assembly comprising: an interior assembly including an interior actuator manually operable to move the bolt between the retracted position and the extended position; an exterior assembly including an exterior actuator manually operable to cause the bolt to move from the retracted position to the extended position and inoperable to move the bolt from the extended position to the retracted position; a driver extending from the interior assembly to the exterior assembly, the driver rotatable from a locked position to an unlocked position such that when the driver is in the locked position, the bolt is in the extended position and when the driver is in the unlocked position, the bolt is in the retracted position; a driver member coupled to the driver for rotation with the driver; a driver actuator rotatable with respect to the driver and movable between a loaded position and an unloaded position, the driver actuator including an engaging portion selectively engagable with the driver member; a biasing member that biases the driver actuator toward the unloaded position; and a latch member that selectively engages the driver actuator to retain the driver actuator in the loaded position, wherein the exterior actuator is manually operable to disengage the latch member from the driver actuator to cause the biasing member to rotate the driver actuator toward the unloaded position such that the engaging portion of the driver actuator engages the driver member to rotate the driver member and the driver toward the locked position to move the bolt to the extended position.
