  • Patent number: 5655306
    Abstract: A vehicle mounted backing distance gauge is provided, in which a plunger, normally biased to an extended position, extends approximately ten inches behind the vehicle, and as the vehicle is backed toward an object such as a loading dock, the plunger comes into contact with the object and retracts into a casing mounted to the driver's side of the vehicle. The plunger has an internal beam that moves in concert with the plunger, and through the use of a bevel gear pair and a follower arm controllably moved by the forward end of the internal beam, an indicator sign is rotated or pivoted by a shaft coupled to one of the bevel gears from a first position parallel to the side of the vehicle and extending toward the rear of the vehicle, to a diametrically opposed position parallel to the vehicle, but extending toward the front of the vehicle.
