ABSTRACT:
A vehicle restraint for preventing a vehicle, such as a truck, from pulling away from the loading dock during a loading operation. The vehicle restraint includes a frame or supporting structure which is mounted on the generally horizontal driveway in front of the loading dock, and a parallelogram linkage inerconnects the frame and a hook. The parallelogram linkage includes two pair of generally parallel links and the lower ends of both pairs of links are mounted for movement on the frame in a direction toward and away from the dock, while the upper ends of the links are pivotally connected to the hook. A reciprocating drive mechanism interconnects the frame and the linkage, and by moving the lower ends of the links in a direction toward the loading dock, the hook will be moved upwardly in a vertical path to engage an abutment on the rear end of the truck to prevent the truck from accidentally moving away from the loading dock. By moving the drive mechanism in the opposite direction, the lower ends of the links will be moved in a direction away from the dock to thereby lower the hook to an inoperative or storage location adjacent the driveway.
