Device for releasably securing a vehicle to an adjacent support

Abstract

A device is provided for use in releasably securing a vehicle against a loading dock during loading and unloading of the vehicle. The device comprises a hingedly mounted vehicle-engaging member located adjacent a front wall of the dock and beneath the plane of the dock loading surface. A handle is provided for effecting controlled movement of the member between an inoperative mode and an operative mode. When in an operative mode, a portion of the member interlocks with a component of the vehicle and restrains movement of the vehicle away from the loading dock. When in an inoperative mode, the member assumes a vehicle-release position wherein the vehicle is free to move away from the loading dock.
