  • Golf club with optimum moments of inertia in the vertical and hosel axes
    Patent number: 8333668
    Abstract: A hollow golf club is provided having an outer shell and an inner frame. The outer shell comprises one or more lightweight members. The inner frame fits within a smaller envelope and sits on the sole of the club head. One or more weights are located either on or within the inner frame 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, referred to as the “y-axis,” and the axis running through the center of the shaft of the golf club, 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.
