First Claim
Patent Images
1. A golf shaft comprising:
- an elongate substantially cylindrical shaft member having a tip end and butt end;
the shaft member including a tip section adjoining the tip end, butt section adjoining the butt end and midsection therebetween, the tip section, butt section and midsection being formed at least partially from composite material;
at least a portion of the tip section having at least one reduced neck portion; and
a deflection limiting outer sleeve which is bonded to an outer surface of the tip section and overlies the neck portion, the sleeve having a centrally located gap filled with a compressible material, and the gap extends 360 degrees around the sleeve.

Abstract
A golf club and golf club shaft includes a tubular member having at least one neck portion with a reduced outer diameter and at least one relatively rigid two-piece sleeve secured to the tubular member in overlying relationship to each neck portion. The two-piece sleeve defines a small central gap filled by a compressible ring to allow the two otherwise longitudinally aligned sleeve pieces to pivot relative to one another under dynamic loading of the tubular member during a golf swing, and then upon reaching a limit point restrict additional deflection or bending of the tubular member.

10. A golf shaft comprising:
-
a hollow graphite tube having a tip end and butt end; the tube having a first neck section; a first deflection limiting sleeve bonded to an outer surface of the tube overlying the first neck section; the sleeve being formed of a material having a stiffness sufficient to restrict local flexing of the tube, and having a centrally located gap extending 360 degrees around the sleeve filled with a compressible material to allow portions of the sleeve on opposite sides of the gap to pivot relative to one another as the compressible material compresses. - View Dependent Claims (11)
