ABSTRACT:
An adjustable head golf club has a selection ring (16) positioned with shank end ratchet teeth (19) in ratchet relationship to shank ratchet teeth (20) and with head end ratchet teeth (17) in ratchet relationship to head ratchet teeth (18). A fastener rod (4,10) is extended intermediate a club attachment base (11) on the back side (29) of the club head (1) and a shank attachment base (12) on a shank (2). A fastener head (44, 45, 46) of the fastener rod can be buttressed either against an inward side of the club attachment base or against an outward side of a shank attachment base, depending on design preferences. A plurality of shank end ratchet teeth and shank ratchet teeth is different from a plurality of head end ratchet teeth and head ratchet teeth. The shank end ratchet teeth are designedly offset circumferentially to provide vernier type adjustment of face angle loft and handle angle lie by selective circumferential positioning of the selection ring between the head ratchet teeth and the shank ratchet teeth according to an alignment radius (62), alignment marks (63) and mode letters (60). For closed positioning of a telescopically closeable handle for travel mode, a shaft ring or ferrule (56) on the shaft is designedly eccentric to maintain closed mode conveniently.
