ABSTRACT:
An apparatus and process are disclosed for releasably attaching golf club heads, and particularly putter heads, to a golf shaft to permit easy interchange thereof. A golf putter 10 (FIGS. 1 and 2) including an elongated shaft 11, a hand grip 13 on one end, and an opening 15 at the other end thereof, is disclosed. A hollow insert 17 is fixedly attached (via adhesive bonding, soldering, or the like) within the open end 15 of shaft 11. The interior open area of insert 17 has a cross-sectional area in the form of a square, hexagon, octagon, keyway, or other angular surface shape and serves to receive a shank 19 of putter head 20 therein. The angular exterior surface of shank 19 is the male counterpart of the female opening of insert 17 and is adapted to snugly fit therein. Screws 25, 27 are threadedly inserted through transverse spaced bores formed through the club shaft 11, insert 17 and shank 19 to releasably attach putter head 20 to shaft 11. Interchanging of different putter heads involves only removal of screws 25, 27, removing the old putter head, inserting a new putter head within the insert and replacing screws 25, 27. In the embodiment of FIG. 10 a rod section 105 is attached to a putter head hosel 102 to provide the shank for attachment to shafts of the type shown in the other embodiments.
