Golf club stabilizer
First Claim
1. A shaft stabilizer for hollow shaft golf clubs of the type having a shaft with a grip end at one end of the shaft and a head end at the opposite end of the shaft, comprising:
- a plurality of radially expandable discs spaced from one another along the shaft; and
a common activating rod operatively connected to each disc for selectively expanding the discs radially outwardly into tight engagement with the hollow shaft to stiffen the shaft at such points of engagement.

Abstract
A golf club stabilizer having a plurality of radially expanded rubber discs all energized by a single threaded energizing rod. All of the discs can be expanded into contact with the shaft of the golf club uniformly or they can be varied in selectively different amounts. The discs can all be tightened to make the club very stiff or they can be tightened only loosely to make the club more stiff than without the discs but less than with fully tightened discs. The kick point of the club can also be varied by leaving some of the discs in a relaxed state out of contact with the shaft and doing this with any of the discs along the several discs in the club.

8. A shaft stabilizer for changing the stiffness of the grip end of the hollow shaft of a golf club having a grip end and a head end, comprising:
a plurality of spaced friction members within said grip end of the shaft, the friction members being spaced from one another along the shaft and a rigid energizing rod operative to simultaneously and uniformly radially expand all of the spaced friction members into tight engagement with said shaft to stiffen the grip end of the shaft uniformly along the length of said combined friction members and rod, thereby reducing the flex of the entire shaft and reducing twist in the grip end of the shaft. - View Dependent Claims (9)

10. A shaft stabilizer for varying the stiffness of the grip end of a hollow golf club shaft having a head end and a grip end, comprising:
a plurality of friction members spaced from one another along the inside of said hollow shaft at the grip end, and an energizing rod joined to said friction members and operable to selectively radially expand any combination of said friction members for varying the stiffness along the length of the grip end to give the club an adjustable stiffness in the grip end of the shaft. - View Dependent Claims (11, 12, 13)

14. A shaft stabilizer for changing the stiffness of a hollow shaft comprising:
-
an elongated spacer energizing rod, a plurality of friction members spaced from one another along said rod, said friction members including means adapted for radially expanding selected said friction members when placed in contact with a hollow shaft into tight engagement with said shaft to stiffen the shaft along the length of said selected friction members and rod, said friction members including a plurality of radially expandable discs, said discs each including a robber sleeve having a cylindrical body and having a nut secured thereto, and an elastic cylinder fitted over said sleeve cylindrical body, said energizing rod including, means for fixing each disc against movement along the rod, and wherein rotation of the rod moves the nut along the rod to radially expand the cylindrical body of the sleeve and thence the elastic cylinder fitted thereon. - View Dependent Claims (15)
