  • Patent number: 5366264
    Abstract: A vehicle bumper ram guard assemblies for wheeled vehicles which are used to push other vehicles or objects. Each ram guard assembly comprising an upright elongate ram cylinder made of impact absorbent material and rotatably mounted on a U bracket which is in turn secured to the pushing vehicle's structure. Preferably the ram cylinder apart from being rotatable is also vertically movable so as to dissipate and minimize frictional forces on the object being pushed. A non-abrasive cover may cover the ram cylinder to further minimize frictional forces and consequent damage to the object being pushed.

  • Patent number: 4273369
    Abstract: A reversible push block-rear bumper assembly for attachment to a motor vehicle is provided in which a support unit having a forwardly inclined downwardly extending surface is secured to the underside of a vehicle in close proximity to the rear end of the vehicle. A block unit having an upper incline surface which can be mated with the forwardly incline downwardly extending surface of the support unit is also provided, such surfaces being adapted so that when the block unit and support unit are secured together, the block unit will either extend downwardly from the support unit in a plane substantially perpendicular to the longitudinal plane of the vehicle and thus function as a bumper or, upon rotating the block unit 180.degree. into a reverse position, the block unit will extend outwardly from the rear end portion of the vehicle for use as a push block. An extension unit for modifying the length as well, as the angular relationship of the block unit to the support means, is also provided.
