ABSTRACT:
An automatic vehicle chock has a chock and a locking mechanism movable on a rail from a retracted position to a position where the chock is extended and held in position by the locking mechanism. A sensor moves with the chock to determine the position of the wheel to be chocked and extend the chock. The position of the sensor relative to the chock can be adjusted. The device also employs mechanical assemblies carried by the carriage assembly to retract the chock without the use of a brake. In one embodiment a cam is used to reverse the direction of the chock arm retaining spring after the chock has been engaged. In a second embodiment the chock is continuously biased to the stored position and a latch is used to hold the chock outward until it is locaked in posiion. The latch is then released and the bias to the stored position is restored so that the chock will retract when the lock is released.
