  • Patent number: 5816602
    Abstract: A stopper for a snow board operates to stop sliding of the snow board when a boot is removed from a binding, and to allow sliding of the snow board when the boot is mounted on the binding. The stopper is formed of a stopping device including a base member attached to the snow board or binding, a cylindrical member attached to the base member, and a rod slidably situated in the cylindrical member; a spring attached to the base member for urging the rod in the cylindrical member downwardly; and an operating device having an operating portion linked to the rod for operating the rod in the cylindrical member. When the operation portion is moved to a lower position by an outer force, e.g. boot, the rod is moved to a retracted position, and when the operating portion is in an upper position by the spring, the rod is held in a projecting position to allow the rod to operate as a stopper.

  • Patent number: 5803829
    Abstract: A golf club of the invention is basically formed of a head, grip and shaft for connecting the head and grip. The head of the golf club has a sweet spot on a face surface thereof. A hollow passage extending through the grip, shaft and head is formed in the golf club, and reaches a location behind the sweet spot at the face surface of the head. Weighted materials, such as iron beads are contained in the hollow passage. When the golf club is swung to a top of back swing, the iron beads are positioned adjacent the forward end of the grip, i.e., such as the lowest end of the golf club. However, when the golf club is swung to a point of impact, the iron beads, or other materials reach the sweet spot at a high speed in receipt of a centrifugal force of the golf club to thereby increase a driving force to be applied to a ball. Thus, a flying distance of the ball can be greatly increased without changing the exterior shape or material of the face surface of the head.
