  • Publication number: 20020061788
    Abstract: A golf club head that includes a hosel and a metal blade. The metal blade includes a knife-like leading edge at the juncture of the sole and striking face, a sole with a rounded protrusion, and a rear face that extends from the sole's protrusion to the trailing edge of the striking face. The knife-like leading edge allows the club head to easily cut through high grass behind the golf ball, thus prohibiting the grass form turning or twisting the club head. The rounded protrusion of the sole prevents the head from cutting too deeply into the ground surface.

  • Patent number: 6149533
    Abstract: A golf club includes a head having a striking face, a threaded cylindrical chamber behind and generally parallel to the face, a cylindrical weight member threaded in the chamber, a hosel attached to the cylindrical weight member having a shaft receiving socket with a non-circular portion and a threaded portion, a shaft having a hosel engaging end with a mating non-circular cross section and a ferrule having threads engagable with the threaded portion of the socket. An additional weight is adjustable in the chamber to provide the desired balance characteristics to the club. A second embodiment includes a head which is symmetrical so that the hosel may be attached at either end to make the club ambidextrous. Some different structures for attaching the hosel to the cylindrical weight member provide for variations in the loft of the club.

  • Patent number: 6001024
    Abstract: An adjustable golf club having means for adjusting the balance of the club and means for adjusting the alignment angle of the club. A club head is attached to the connection end of the shaft by connecting means at a connection point along the heel-to-toe axis and at a line-of-play alignment angle and a heel-to-toe alignment angle. The connecting means includes a slide fixed to the connection end of the shaft and a socket in the top portion of the club head. The balance of the club can be adjusted by linearly moving the slide along the heel-to-toe axis in the socket. The line-of-play alignment angle of the shaft can be adjusted by rotatably moving the slide in the socket. After the club is adjusted, the slide is secured in the socket by locking means to prevent the club from deviating from the desired adjusted configuration during play. A method of putting a golf ball with the above provided adjustable putter. The adjustable putter is provided to the golfer.

  • Patent number: 5873791
    Abstract: A wood-type golf club having an enlarged club head in the range of 250 to 300 cm..sup.3 constructed of a material lighter than steel to maintain the total club head weight within normal limits including the weight of a novel power shaft according to the present invention. The club head, without the power shaft, is approximately 175 gms. and the power shaft weighs approximately 25 gms., so the total club head weight is approximately 200 gms. and within normal limits. The power shaft, integral with the rear of the ball striking face wall at its forward end and integral or cast into the rear of the club head at its rear end, while reinforcing the ball striking face wall, increases the resonant frequency of the face wall to synchronize face wall rebound to the player's swing speed. Face wall resonant frequency is varied by changing the size and weight of the power shaft.

  • Patent number: 5603666
    Abstract: A golf putter has a putter head having forward, rearward, top and bottom surfaces, and opposite ends. A cavity opening is centrally located in the top surface of the putter head. An elongated shaft with a ball on the lower end thereof extends into the cavity. A detent on the ball engages a detent in the bottom of the cavity to prevent the longitudinal axis of the golf shaft from forming an angle of less than 10 degrees with a vertical axis extending upwardly from the cavity and the putter head. The shaft is locked within the putter head by three screws. Two opposite screws extend into the cavity from a threaded longitudinal bore which extends through the putter head. A second transverse screw extends into the cavity through the putter head. When tightened, the three screws mechanically lock the ball on the lower end of the shaft in the desired position.
