Abstract:
An improvement for a vehicle restraint adapted to be mounted adjacent a face of a loading dock for selectively restraining the ICC bar of a vehicle parked adjacent the loading dock, and including a frame disposed adjacent the dock face and a restraining member extending away from the dock face and capable of substantially vertical movement relative to the dock face and along the frame to a position wherein the restraining member restrainingly engages an ICC bar of a parked vehicle, the restraining member including a shank portion having a first end operatively connected to the frame for movement therealong, and a head portion connected to the shank portion, the head portion being disposed substantially parallel to the dock face for preventing the restrained ICC bar from moving away from the dock face with the restraining member in the restraining position, the restraining member being susceptible to being canted such that the head portion of the restraining member initially moves downward away from the restraining position, followed by the remainder of the restraining member moving downwardly away from the restraining position in response to movement of the parked vehicle away from the dock face with a force above a predetermined magnitude, said movement defining a pull away the improvement comprising:a locking device for locking the restraining member against downward movement during said pull away, the locking device being disposed and actuated to allow free movement of the restraining member relative to the frame for normal operation of the vehicle restraint, and for preventing at least downward movement of the restraining member during said pull away.
