  • Golf club having hollow shaft with fluid selectively installed therein
    Patent number: 5316300
    Abstract: A column of high viscosity fluid is installed in a selected portion of the hollow shaft of a golf club. This fluid which does not flow readily reinforces the shaft and minimizes the bending and deformation thereof during the golf stroke. The location along the shaft at which the fluid column is installed is selectively chosen to provide an optimum natural vibration frequency for the shaft, a location closer to the club head providing a lower natural vibration frequency.
