  • Patent number: 7976415
    Abstract: A racket. In an illustrative embodiment, the racket includes plural handle portions, including a first handle portion and a second handle portion, which are equipped with a first gripping surface and a second gripping surface, respectively. A first mechanism couples the first handle portion and the second handle portion to the racket so that the first gripping surface is angled relative to a first plane coincident with a hitting surface of the racket. In a more specific embodiment, the first handle portion and the second handle portion are integrated with the racket. Alternatively, the first handle portion and the second handle portion are removably attached to the racket. The first and second handle portions form obtuse angles between the hitting surface and the handle portions.

  • Patent number: 4861030
    Abstract: A racquet for use in tennis, racquetball, squash and badminton, having an oval or round head, two symmetrical shafts forming the racquet handle and two grips that are offset from the centerline of the handle. The grips may be angled or paralleled with the centerline. In the preferred embodiment, an adjustable torque stabilizer connects the two grips, providing torsional rigidity and permitting adjustment of the space between the grips. The racquet grips are configured so that the player holds the racquet by both grips, and can simply let go of one grip and swing the racquet with the other hand to play `forehand` shots, thus eliminating the critical time normally taken to switch grips.

  • Patent number: 4473235
    Abstract: Apparatus is provided for improving control of snow skis while reducing likelihood of injury and permitting use of relatively flexible and comfortable ski boots. The apparatus comprises a leg support assembly extending upwardly from the laterally outside edge of the ski for connection by use of a wraparound cuff to the skier's leg at a position slightly below the knee. The leg support assembly is adjustable to permit a selected degree of unrestrained flexion of the leg, including the knee and the ankle, in a longitudinal direction with respect to the ski for enhanced ski control and reduced muscular fatigue. However, the leg support assembly is laterally rigid to transmit lateral movements of the leg directly to the outside edge of the ski for improved edging during turns, while the cuff helps to prevent inward twisting of the knee during edging to reduce likelihood of injury.
