ABSTRACT:
A collapsible golf club. A head is disposed on a shaft and a coupling replaceably couples an end of the handle to an end of the shaft. The coupling includes a threaded portion extending from the end of the shaft, a stub shaft extending from the threaded portion, a pair of pins extending radially outwardly from the stub shaft, a tube extending from the end of the handle and having a pair of slots and a shoulder, and a sleeve having an internal threaded portion and terminating in a lip. The tube is rotatably captured in the sleeve, up against the internal threaded portion, and is maintained therein by the lip providing a stop for the shoulder, thereby rotatably attaching the sleeve to the tube. The stub shaft passes through the internal threaded portion and into the tube, with the pair of pins entering the pair of slots, with the internal threaded portion threadably engaging the threaded portion, and with the sleeve being rotated until the pair of pins snug into the pair of slots, thereby providing a tight joint between the shaft and the handle.
