  • Patent number: 6763747
    Abstract: The present invention relates to a shock absorbing hammer and handle assembly. The shock absorbing hammer includes a hammer head including a striking portion, a shaft connected to the hammer head, and a hand grip. In accordance with aspects of the present invention, a hand grip assembly suitable for use with the shock absorbing hammer includes a shell defining an outer surface and an inner cavity. An inner elastomeric layer lines the inner cavity and defines an opening adapted to receive the shaft of the item. An outer elastomeric layer surrounds the outer surface of the shell. In particular embodiments of the handle grip, the outer elastomeric layer is formed with first and second elastomeric materials, which may define different durometer hardnesses. Still further, the inner elastomeric layer may also be formed with the first elastomeric material. In accordance with another aspects of the present invention, methods of making the novel handle grip are also presented.

  • Patent number: 6128977
    Abstract: A shock-absorbing claw hammer includes a handle, a claw and a striking head. Vibrations in the handle caused by the striking head striking an object are at least partially reduced by shock-absorbing means. In one embodiment, the head includes a top surface and a lower surface, with the lower surface of the head coupled to the handle. The claw includes a first slit for pulling nails, and the head further defines a second slit extending from the top surface of the head towards the lower surface of the head situated generally between the striking head and the claw. In another embodiment, tension and compression rebars are positioned within the handle, with the striking head coupled to the compression rebar and the claw coupled to the tension rebar such that the striking head and the claw move relative to one another upon striking an object.
