Abstract
A wheel restraint includes a wheel chock that is manually movable between a retracted position clear of a wheel of a vehicle at a loading dock and an operative position to block the path of the wheel. In the retracted position, the chock can be manually moved freely along a track that is mounted to a driveway of the dock. When the chock is manually moved from its retracted position to its operative position, a locking feature automatically restricts the movement of the chock relative to the track. When the chock is manually moved back to its retracted position, the locking feature automatically disengages. Although the wheel chock is connected to a track, most of the force exerted by the wheel against the chock is transmitted directly from the chock to the driveway.
