Abstract
A vehicle restraint for preventing a vehicle or truck from accidentally pulling away from a loading dock. The truck restraint comprises a frame to be mounted on the vertical front face of the loading dock and a restraining member is mounted for pivotal movement in a generally vertical plane parallel to the dock face between a first lower storage position and a second operative position where the restraining member will prevent outward movement of the truck away from the dock. A curved plate or abutment is mounted in spaced relation to the frame and extends throughout the length of the path of pivotal movement of the restraining means. The restraining member is normally disposed out of contact with the abutment as the restraining member pivots between the storage and operative positions. In the event the truck attempts to pull away from the loading dock while the restraining member is in the operative position, the outward force applied by the truck to the restraining member will deflect the restraining member outwardly into contact with the abutment to thereby restrict further outward movement of the restraining member. The restraining member is urged to the operative position by a resilient biasing member and the biasing member is movable between a first position where the force of the biasing member overcomes the weight of the restraining member and acts to urge the restraining member to the operative position, and a second position where the force of the biasing member is overcome by the weight of the restraining member so that the restraining member will move by gravity to the storage position.
