Abstract: A bumper assembly for a loading dock includes a bumper that is moveable between an operative position and a stored position. In the operative position, the bumper extends well above the dock platform to prevent excessively high trucks, trailer beds, and cargo containers from being parked over the top of the dock platform. In the stored position, the bumper is positioned so as not to obstruct loading and unloading of cargo. In some cases, the bumper is biased to the operative position to encourage operators to normally leave the bumper in that position. In some embodiments, the bumper is selectively moveable away from the vehicle or container that the bumper is blocking to facilitate subsequently moving the bumper to its stored position.

Abstract: A wheel-activated vehicle restraint system including a support structure disposed beside the path of the vehicle approaching the dock, and including a guide member extending away from the dock face, and an elevated supporting member. A trigger assembly is operatively connected to the guide member, and initially engages the wheel of the vehicle as it rolls toward the dock. A locking arm operatively engages the supporting member to move from a stored position to a chocking position on the wheel as the wheel engages the trigger and moves it toward the dock. A trolley assembly operatively connects the trigger assembly and the locking arm, the trolley assembly and the locking arm being connected at a connection point.
