  • Patent number: 7445016
    Abstract: A shock absorbing cane, including a shaft and a handle, the shaft having a self propelling and repositioning forward motion when compressed handle is lifted by user. The shaft extends from the handle and the handle is shock-absorbing for absorbing impact when the shaft strikes against an unyielding surface. The handle includes a fixed portion, a movable portion, and a dampening assembly. The fixed portion is affixed to the shaft and the movable portion is movably mounted to the fixed portion. The dampening assembly includes a tension spring disposed in the fixed portion of the handle, with one leg thereof extending into the shaft to preload the tension spring by biasing against the shaft, and with the other leg thereof extending via a rod into and affixed to the movable portion of the handle, thereby allowing the movable portion of the handle to resiliently move relative to the shaft and absorb impact when the shaft strikes against the unyielding surface.

  • Patent number: 4550916
    Abstract: Cube game of skill and chance in which players insert rod shaped playing piece through apertures on one face of a hollow cube. Long pieces protrude through opposing holes on the opposite playing surface and short pieces do not. Either playing pieces dislodge the opponent's playing piece if it occupies a corresponding aperture. Unique light blocking channels between opposing apertures are formed from either drooping flexible tubing or drooping collapsible woven mesh tubing. The collapsed channels block light when no playing piece is present and open to allow the insertion of the playing pieces. Playing pieces may be assigned both negative and positive scoring value. Pads are provided to protect the expelled piece and the surface upon which the game is placed.
