20090156325 | Attachment system for detachably securing a component to a shaft-like member - An interchangeable threaded attachment means for securing a given object to a shaft. By way of example and not limitation, the attachment means is embodied in a golf club assembly, providing for the use of multiple golf club heads with a single shaft. The assembly means comprises a threaded collet adaptor which clamps onto the lower portion of a golf club shaft and is threaded into a female aperture on the top of a golf club head. The threaded female aperture has a series of progressively ramped threads which locks the male threaded collet adapter securely in place when tightened, thereby eliminating the lateral thread clearance and converting some of the axial tension, seen in typical 60° threads, to radial or compressive forces on the male threads. This design utilizes the compressive forces to compress the male thread component, gripping the shaft, and eliminating all clearances in the threaded joint that can allow vibration or noise in the joint. | 06-18-2009 |
