  • Patent number: 6826854
    Abstract: An inner circumference side annular groove is formed in an inner circumference edge part of a golf shoe sole of a synthetic rubber, an outer circumference side annular groove is formed in the radial outside of the annular groove, and an annular packing protrusion is formed between them. An inner circumference side annular rib is provided on the lower face of the base of the friction part, an outer circumference side annular rib is provided in the outer circumference edge part thereof, and the area between them is made an annular packing face. When the friction body is fitted in and held by the holder, the inner circumference side annular rib and the outer circumference side annular rib fit in the inner circumference side annular groove and the outer circumference side annular groove, respectively, and the annular packing protrusion tightly and elastically contacts and presses the annular packing face over the entire circumference.

  • Patent number: 6513266
    Abstract: The thick-walled cylindrical portion 12 of a holder 10 is provided with axial grooves 18 that open to the inner peripheral surface. In the axial grooves 18, slip-off preventive projections 20 are radially inwardly elastically urged by their own elasticity. The substantially disk-like antislip portion 54 of an antislip body 50 is centrally formed with a cylindrical antislip body-associated fitting portion 56 projecting downward therefrom. The antislip body-associated fitting portion 56 is formed with a circumferential annular slip-off preventive groove 58 disposed somewhat above the lower end thereof. The antislip portion 54 is formed with antislip body-associated insert receiving portions 60 extending therethrough and disposed at positions corresponding to the slip-off preventive projections 20. Once the antislip body-associated fitting portion is fully to the holder-associated fitting portion, the antislip body can be easily and reliably held in the holder without using any tools.

  • Patent number: 5330193
    Abstract: A golf swing practicing article which is shorter in overall length than an ordinary golf club and substantially symmetrical around a center axis of a shaft body includes a grip member disposed at first end section of the shaft body and a weight member at an opposite second shaft body end section, the weight member increasing the mass at the said second end section, the weight member occupying 40 to 60% of said overall length. The weight member can have a tapered portion and a receiving portion for reception and removal of weights so as to vary the weight of the weight section, the weights being cylindrical members of different sizes and such that certain of same fit inside others of the weights.
