Abstract:
1. A length adjustable golf putter, comprising a puffer assembly, the assembly including a putter shaft and an extender sleeve separate from and mountable to the puffer shaft, the putter shaft having a lower end portion formed with a putter head and a hollow upper end portion having an open upper end, and said extender sleeve having upper and lower end portions, the lower end portion of said extender sleeve fitting slidably in concentric, telescoping relation into the hollow upper end portion of said putter shaft such that the extender sleeve is axially positionable in the hollow upper end portion of the putter shaft, and means for releasably locking the lower end portion of the extender sleeve relative to the upper end portion of said putter shaft whereby said extender is able to be telescopically adjusted and axially secured as desired relative to the putter shaft and the length of said putter assembly changed as desired, said means for releasably locking including a pair of nested lock members, one said lock member being fixedly disposed at the lower end of the extender sleeve and the other said lock member forming a radially expansible socket which receives and into which said one lock member is nested, and means for mounting the lock members in nested relation and in a manner that said other member is able to be axially urged towards and away from the expansible socket in an amount sufficient to cause the expansible socket to expand radially outwardly and inwardly and into and from frictional locking engagement with the inner wall of said putter shaft, the nested relation and shapes of the lock members being such that the lock members do not rotate relative to one another wherein said one lock member comprises a pair of angled surfaces that form a V-shaped nose and the other lock member comprises a pair of resilient radially deflectable cantilever lock beams that are mirror images of one another and include a pair of flat faces both in length and width that form a V-shaped throat, and the angled surfaces of the V-shaped nose engaging the flat faces and operating to deflect the lock beams radially outwardly.
