Patent ID: 8641551

Claim:
A golf club weighting plug system for providing a user-selectable swing-weight firmly secured in a damped manner as a plug assembly locked at a user-selectable desired location in a shaft of a golf club, comprising: at least one cylindrical weight rod, a first of which is designated as the primary weight rod, made available in different materials, lengths and weights to provide a predetermined mass, configured, at least at an upper end thereof, with a coaxial central threaded bore of designated diameter and pitch; damping support means for preventing direct contact between said weight rod and the shaft of the golf club, while providing support therebetween that provides a sliding fit and vibration-damped support; a cylindrical expansion element made from resilient material and configured with a coaxial central bore, made and arranged to be clamped against the upper end of said weight rod by a machine screw of the designated diameter and pitch traversing the bore of said expansion element and engaging the coaxial threaded bore in said weight rod, said expansion element being made and arranged to initiate a slidable mode of the plug assembly whenever said expansion element is held in an unexpanded threshold condition due to the screw being loosened sufficiently counterclockwise to disengage said expansion element from the shaft and thus allow sliding of the plug assembly, and to initiate a locked mode wherein said expansion element is held in a fully expanded condition due to the screw having been tightened clockwise sufficiently to lock the plug assembly in place in the shaft for golf play.
