Adjustable Shaft Length Patents (Class 473/239)
  • Patent number: 5569096
    Abstract: A golf club putter having adjustable lie angle and shaft length comprises as major components a hollow handle, a shaft length adjusting mechanism, a shaft, a lie angle adjusting mechanism, and a putter. With the shaft inserted into the handle, threadably tightening a locking nut over a flexible ring and a external thread until the flexible ring is squeezed over the shaft prevents the shaft from slipping--thereby effectively locking the shaft in the desired length. When the locking nut is threadably loosened, the flexible ring is relaxed around the shaft and thereby the shaft is free to be lengthened or shortened. Applying an angular pressure to upper portion of the shaft bends bendable metal piece whereby a desired angle is achieved.

  • Patent number: 5538245
    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.
