OG exemplary drawing
 
1. A lock apparatus, comprising:
a case;
a motor mounted in the case;
a manual actuator;
a lost rotational motion assembly mounted in the case, the lost rotational motion assembly comprising:
a first component configured for connection with a bolt, wherein the first component is rotatable between first position and a second position, wherein one of the first position or the second position is a bolt-extending position, and wherein the other of the first position or the second position is a bolt-retracting position;
a second component operably connected with the motor such that the motor is operable to rotate the second component in each of a first rotational direction and a second rotational direction opposite the first rotational direction between a home position and a first rotated position, the second component including a pocket; and
a coil spring extending between the case and the first component, the coil spring axially urging the first component into the pocket of the second component in order to couple the first component with the second component;
a position sensor coupled to and moveable with the first component, the position sensor operably connected to control circuitry connected with the motor, the position sensor operable to indicate to the control circuitry that the first component has reached the first position and the second position; and
a lock cylinder connected with the first component, wherein the lock cylinder is operable to move the first component between the bolt-extending position and the bolt-retracting position while the second component remains in the home position;
wherein, with the first component in the first position, rotation of the second component in the first rotational direction from the home position to the first rotated position drives the first component from the first position to the second position;
wherein the first component is configured to remain in the second position during rotation of the second component in the second rotational direction from the first rotated position to the home position; and
wherein the manual actuator extends through an opening of the first component, and wherein depressing the manual actuator axially displaces the manual actuator and the first component to compress the coil spring between the case and the first component and decouple the first component from the second component during operation of the lock cylinder to manually move the first component between the bolt-extending position and the bolt-retracting position so that the second component remains in the home position.
