20080274822 | Apparatus For Weighting Golf Club Shaft - An apparatus for selectively adding weight to the hollow shaft of a hand-held implement. One embodiment includes an upper cylindrical member, a lower member, and an expansion ring that fits between the upper and lower members. These components are sized slightly smaller than the inside diameter of a hollow shaft, such as a golf club shaft. Each component includes an axial bore, through which a screw with an elongated barrel extends. The axial bore of the upper member is enlarged at its upper terminus to receive the cap of the screw, and the axial bore of the lower member is threaded to receive the screw. This assembly is inserted into a hollow shaft, and as the screw is tightened, the lower member is drawn into the upper member, compressing the expander ring axially causing it to expand radially until a friction fit with the inside surface of the hollow shaft is achieved. | 11-06-2008 |
20080274823 | Apparatus for Weighting Golf Club Shaft - An apparatus for selectively adding weight to the hollow shaft of a hand-held implement. One embodiment includes a deformable upper cylindrical member, a lower member, and a rod coupled between the upper and lower members. These components are sized to fit within a hollow shaft, such as a golf club shaft. The upper deformable cylinder includes a chamber at its upper end, into which an oversized insert is inserted. This causes the deformable cylinder to expand radially creating a friction fit with the inside surface of the hollow shaft. The lower member may include an annular deformable member, such as an o-ring or a sleeve, stretched over its outside surface to create a snug fit within the shaft. | 11-06-2008 |
