Abstract:
1. A wheel restraint system for limiting movement of a wheel of a vehicle at a loading dock that includes a driveway, the wheel restraint system comprising: a track mountable to the driveway; a track follower mounted for translation along the track; a wheel chock movably coupled to the track follower such that the wheel chock is manually and selectively movable between an operative position to provide a barrier to movement of the wheel away from the loading dock, and a retracted position clear of the wheel; and a locking feature associated with at least one of the wheel chock and the track follower, the locking feature movable between an engaged position and a disengaged position, the locking feature to limit relative movement between the track and the track follower when the locking feature is in the engaged position, the locking feature to permit greater relative movement between the track and the track follower when the locking feature is in the disengaged position, manual movement of the wheel chock from the retracted position to the operative position automatically and simultaneously causing movement of the locking feature from the disengaged position to the engaged position, and movement of the wheel chock from the operative position to the retracted position automatically and simultaneously causing movement of the locking feature from the engaged position to the disengaged position.
