摘要： A wheel-activated vehicle restraint for use at a loading dock includes a wheel-blocking barrier that is selectively locked to a frame by a latching mechanism that engages an inverted gear rack. Components of the latching mechanism are arranged to prevent spreading apart upper and lower members of the frame members. The latching mechanism includes an alignment device that helps ensure that the teeth of a latching member positively engages the teeth of the gear rack, thus preventing the teeth from coming together peak-to-peak. An upper rail of the wheel restraint's frame includes a contoured leading edge that smoothly guides the lift of the wheel-blocking barrier from its stored position to its wheel-chocking position. A wheel support is used to prevent a vehicle's mud flap from getting pinched between the vehicle's wheel and a trigger assembly of the wheel restraint.

摘要： A wheel chocking device having a wheel chock that can be raised from a retracted position to a raised position. In the retracted position, the wheel chock is substantially flat, thereby allowing a truck to be driven over the wheel chock. In the raised position, the wheel chock can be engaged with the wheel of a truck to prevent the truck from driving away from a loading dock. As the chock is moved from the distal position, the chock can raise from a lowered position to an intermediate position. The chock is then moved toward the vehicle wheel. Upon contact with the wheel, the chock will raise from the intermediate position to the fully raised position. In another embodiment, the chock can be inserted laterally from the side of the wheel.

摘要： A truck leveler includes a low-profile traffic surface that is pivotally mounted to a driveway approach in front of a loading dock. Pivoting the leveler raises a reat portion of a truck or trailer to the height of the dock. The truck leveler has strength, rigidity and accommodates a retractable or repositionable wheel restraint while maintaining its low profile. This is accomplished by virtue of a raised rear beam and two lateral beams that extend above the traffic surface of the leveler. A central beam allows field assembly of the leveler while adding further to the leveler's strength and rigidity.

摘要： 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.

摘要： 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. The trigger assembly is selectively positionable relative to the connection point in response to the dimensions of the wheel, and the locking arm engages a bottom portion of the wheel, and moves along the peripheral surface of the wheel to a chocking position as the wheel continues to push the trigger assembly toward the dock.
