Claim Text:
1. A lock assembly for use with a latch movable from an extended position to a retracted position, the lock assembly comprising: an interior handle manually operable to move the latch from the extended position to the retracted position; an interior locking actuator located on an exterior of the interior handle, the interior locking actuator manually movable from an unlocked position to a locked position; a biasing member that biases the interior locking actuator toward the unlocked position; a retaining member that retains the interior locking actuator in the locked position against the bias of the biasing member; an exterior handle; a driver rotatable from a locked position to an unlocked position such that the exterior handle is manually operable to retract the latch when the driver is in the unlocked position and the exterior handle is inoperable to retract the latch when the driver is in the locked position; and an interior spindle rotatable with the interior handle to move the latch from the extended position to the retracted position, wherein the interior locking actuator is manually pushed and manually rotated to move the locking actuator from the unlocked position to the locked position, wherein when the interior locking actuator is in the locked position, movement of the interior handle to retract the latch causes the biasing member to move the interior locking actuator toward the unlocked position, wherein the retaining member engages the interior locking actuator and the interior spindle to retain the interior locking actuator in the locked position, wherein rotation of the interior handle disengages the retaining member from the interior locking actuator and the interior spindle to allow the biasing member to move the interior locking actuator toward the unlocked position, wherein the interior spindle is generally cylindrical, and wherein the retaining member is at least partially located within the interior spindle.
