The present invention is a continuation-in-part of pending U.S. patent application Ser. No. 11/461,132, filed on Jul. 31, 2006, which is a continuation-in-part of U.S. patent application Ser. No. 10/904,581, which was filed on Nov. 17, 2004, now U.S. Pat. No. 7,083,529.
One aspect of the present invention is a golf club including a club head, a tube, a shaft, a sleeve and a mechanical fastener. The tube, which is mounted in the club head, has a tapered portion, a rotation prevention portion, and an upper end inner diameter that is larger than the inner diameter at the lower end. The rotation prevention portion of the tube defines a keyway that has a non-circular configuration. The sleeve is mounted on a tip end of the shaft, which is then inserted into the tube. A lower section of the sleeve includes a frustoconical portion and a keyed portion. When the shaft is connected to the club head, the frustoconical portion and keyed portion of the sleeve are respectively received in the tapered portion and keyway portion of the tube. The frustoconical portion of the sleeve extends at least one eighth of the length of the lower section of the tube to provide an increased surface area for contact with the tapered portion of the tube.
FIG. 18 is an exploded view of another alternative sleeve having a multi-piece construction.
FIG. 19 is a front plane view showing the alternative sleeve of FIG. 18 fully assembled.
FIG. 20 is a partial sectional view taken along 20-20 of FIG. 19.
As shown in FIGS. 1 and 2, a golf club is generally designated 20. The golf club 20 has a club head 22 and a shaft 40 that is coupled to the club head 22. The club head 22 is a wood-type golf club head with a body 23 having a crown 24, a sole 26, a ribbon 28 and a striking plate 30. The striking plate 30 generally extends along the front of the club head 22 from a heel end 32 to a toe end 34. The club head body 23 preferably has a hollow interior with an internal hosel 31 (FIG. 3) for receiving the tip end of the shaft 40.
Alternatively, as illustrated in FIGS. 18-20, the sleeve 46 may have a multi-piece construction to reduce the weight of the connection 42 without compromising its strength. The sleeve 46 may include a first part 250 and a second part 252. The first part 250 is preferably composed of a metallic material, such as the aluminum alloys and the titanium alloys disclosed above with respect to the tube 44. The first part 250 comprises a tubular section 254 and the lower section 70, including the frustoconical portion 72 and the keyed portion 74. The second part 252 is preferably composed of a non-metallic material, such as a reinforced plastic, and may be injection molded. The second part 252 is a conical portion or cap 256 that is located above the plane of the hosel 31. The cap 256 is secured to the tubular section 254 of the first part 250 by an adhesive, such as epoxy. The multi-piece construction enables excess weight from the sleeve 46 to be eliminated. In addition, it lowers the center of gravity of the resulting connection 42 and provides more discretionary mass, which may be distributed strategically about the club head 22 to improve its mass properties.
