ABSTRACT:
The disclosed collapsible golf club shaft is formed of a conventional stepped one-piece tubular golf shaft having diameters progressing from a large ID and OD end to a smaller ID and OD end, being cut in two at the end of one cylindrical axial sections next to the larger axial section, allowing the two pieces to be telescoped together as inner and outer pieces, and shifted then between a collapsed position compactly nested together and an extended operative position with only endmost stepped sections of the pieces yet overlapped at a separable connection between the pieces. A screw can be extended through wall structure openings and threaded into a reinforcing structure inside the inner piece at the connection for locking the pieces together in the extended operative position. A golf club formed from this shaft, with a hand grip on the outer piece and a head on the inner piece, at the opposite ends of the extended shaft, can be collapsible to slightly more than half the length of the extended operative club, for compact storage and handling.
