The second region is thinner than the first region and a third region adjacent to the back-side periphery of the second region. The second region includes the position of an antinode of the primary vibration mode of the sole portion at the time of impact.

  • Patent number: 8177657
    Abstract: The present invention is directed at a quick release connection system to facilitate customization of golf clubs. It can be used to interchange shafts, removable weights, or soleplates quickly and easily. Teeth are disposed on the inside of a frame so that a shaft may be inserted with minimal resistance, but cannot be removed without specific steps which may require the use of a simple tool. Strengthening and interlock devices are provided to ensure performance quality akin to tradition al golf clubs.

  • Patent number: 8105175
    Abstract: A golf club head is presented comprising a sole including a removable panel secured to the sole via a non-threaded attachment assembly. Further, the removable panel may have a large surface area relative to its thickness, resulting in a chip-like or wafer-like weight member. This design allows the mass of the removable panel to be spread substantially along the surface of the sole as opposed to in the interior of the club head. The golf club head may comprise more than one removable panel. A removable panel of the present invention may generally comprise one or more discrete areas of higher basis weight or higher density. Even further, the removable panel may generally be releasably attached via a quick disconnect mechanism that allows easy interchangeability.

  • Patent number: 8025591
    Abstract: A golf club is provided having a hollow body golf club head comprising discrete concentrations of weight or mass located away from the center of gravity or the geometric center of the club head to optimize the moment of inertia of the club head about both the vertical axis running through the center of gravity or geometric center of the club head, hereinafter referred to as the “y-axis,” and the axis running through the center of the shaft of the golf club, hereinafter referred to as the “hosel axis.” The ratio of moment of inertia of the club head about the y-axis to moment of inertia of the club head about the hosel axis is preferably 0.55. More preferably, this ratio is 0.75.
