  • VARIABLE LENGTH GOLF CLUB SHAFT
    Publication number: 20120149487
    Abstract: A variable length shaft assembly comprising at least one upper shaft portion, a lower shaft portion and a threaded fastener, wherein the threaded fastener removably connects the upper shaft portion to the lower shaft portion, is disclosed herein. The variable length shaft assembly may further comprise at least two upper shaft portions having different lengths so a golfer can adjust the total length of the shaft by removing one upper shaft portion and replacing it with another upper shaft portion having a different length. Methods of adjusting the length of a golf club shaft without damaging any portion of the shaft and variable length shaft kits are also disclosed herein.

  • GOLF CLUB HEAD WITH IMPROVED AERODYNAMIC CHARACTERISTICS
    Publication number: 20120129626
    Abstract: Methods of forming a golf club head having improved aerodynamic characteristics are disclosed herein. A preferred method is the largest tangent circle method, which utilizes a Cartesian coordinate system. The method results in identification and measurement of certain club head features, which can be adjusted to improve aerodynamic properties of the golf club head. One method of the present invention lowers the drag of the club head by specifying dimensional relationships of the driver head based on location of apex and nadir points, while another method lowers the drag of the club head by improving overall face design.

  • HOSEL CONSTRUCTION
    Publication number: 20120115632
    Abstract: The present invention relates to a hosel for connecting a shaft to a club head. In one aspect of the invention, the hosel comprises a body having an undercut, wherein the undercut has a maximum cross section which tapers to a minimum cross section and increases to the maximum cross section immediately adjacent the club head. The hosel further comprises a flange section below the hosel and hosel bore above the undercut, the hosel bore section having a length of at least one inch. In another aspect of the invention, the hosel tapers in diameter from a maximum to a minimum width, and has a maximized interior mold line (IML) to improve bendability and weight savings.
