Patent ID: 8177658

Claim:
A golf club weighting system, providing a weight device that can be adjustably secured within a tubular shaft of a golf club within a designated region thereof having a first inside diameter at a lower end and a second inside diameter no smaller than the first diameter at an upper end, comprising: a cylindrical weight sleeve having a designated outer diameter smaller than the first inside diameter, and having a central axial bore of designated screw clearance diameter; at least one cylindrical expansion sleeve of resilient material, having, in an unexpanded state, an outer diameter approximating the designated outer diameter of said weight sleeve, having a central axial bore of the designated screw clearance diameter in a major portion of said expansion sleeve and having a central axial bore of at least the designated screw clearance diameter at a minor end portion opening to an annular flat end surface of said expansion sleeve; a cylindrical threaded bushing, fitted into the minor end portion of the expansion sleeve bore; a machine screw, traversing the bore of said weight sleeve, configured with an enlarged head portion with an underside thereof bearing against a first end surface of said weight sleeve, said machine screw traversing said expansion sleeve and threadedly engaging said threaded bushing; and said weight sleeve and said expansion sleeve being assembled together with said machine screw in threaded engagement with said threaded bushing but initially tightened only to a lightly-stressed threshold condition, thus forming the weight device and initiating a sliding-friction mode wherein a user is enabled to insert the weight device into the golf club shaft and move the weight device to a desired location within the designated region of the golf club shaft, whereupon tightening of said machine screw will compress said expansion sleeve axially and further expand said compression sleeve radially sufficiently to fasten the weight device in an expansion-secured mode in the desired location in the golf club shaft.
