ABSTRACT:
A vehicle restraint for preventing a vehicle, such as a truck, from accidentally pulling away from a loading dock during a loading operation. The vehicle restraint comprises a mounting plate mounted on the front vehicle face of the loading dock and a slide is mounted for movement on the mounting plate and is biased to an upper position. The slide has an inner end pivotally connected to the mounting plate and has an upper surface formed with a notch or recess. The outer surface of the slide slopes downwardly and outwardly at an angle to the horizontal. When a truck backs toward the loading dock, an abutment, such as an ICC bar at the rear end of the truck, will engage the inclined outer surface and wedge the slide downwardly against the force of the biasing member, and the ICC bar will then engage the notch located in the upper surface of the slide. The downward wedging action will pivot the slide upwardly about the mounting frame to progressively decrease the angle of the outer surface with relation to the horizontal. To release engagement of the ICC bar from the notch, a release bar is moved upwardly into engagement with the ICC bar, thereby driving the slide downwardly against the force of the biasing member to release the ICC bar and enable the truck to pull away from the dock.
