Interchangeable shaft system
View Patent ↗A golf club incorporating an interchangeable shaft system includes a shaft, a shaft sleeve, a club head. The shaft sleeve is coupled to an end of the shaft and is received in a hosel included in the club head. The shaft sleeve is removably coupled to the club head. Hosel and shaft sleeve alignment features provide discrete orientations between the shaft and club head.
1. A golf club, comprising:
a golf club head;
an elongate shaft; and
an interchangeable shaft system releasably coupling the shaft to the club head wherein the inchangeable shaft system includes a shaft sleeve assembly including a sleeve body and a tension member coupled to the sleeve body by a flexible coupling,
wherein the interchangeable shaft system includes a tubular wedge member slidably coupled to the shaft sleeve assembly and wherein the shaft sleeve assembly comprises means for capturing the wedge member on the shaft sleeve assembly, and
wherein the interchangeable shaft system provides dual angle adjustability, and wherein the interchangeable shaft system provides at least three discrete orientations of the shaft relative to the club head within a lie plane of the golf club head with a single elongate shaft and interchangeable shaft system.
2. The golf club of claim 1 , wherein the interchangeable shaft system is configured to provide at least four discrete orientations of the golf club head relative to the shaft within the lie plane so that a measured loft angle of the golf club is constant in the at least four discrete orientations.
3. The golf club of claim 1 , wherein the interchangeable shaft system includes a wedge member interposed between the elongate shaft and the club head.
4. The golf club of claim 3 , wherein the wedge member is constructed to have two selectable orientations relative to the club head.
5. The golf club of claim 4 , wherein the elongate shaft is constructed to have two selectable orientations relative to the wedge member.
6. A golf club, comprising:
a golf club head;
an elongate shaft; and
an interchangeable shaft system releasably coupling the shaft to the club head, the interchangeable shaft system comprising a shaft sleeve, wherein a distal end of the shaft is coupled to a shaft bore defined by the shaft sleeve, wherein the shaft bore is angled relative to a body of the shaft sleeve,
wherein the shaft sleeve is a shaft sleeve assembly including a sleeve body and a tension member coupled to the sleeve body by a flexible coupling,
wherein the interchangeable shaft system includes a tubular wedge member slidably coupled to the shaft sleeve assembly and wherein the shaft sleeve assembly comprises means for capturing the wedge member on the shaft sleeve assembly, and
wherein the interchangeable shaft system is configured to provide a plurality of coupling positions with each position producing a specific combination of a loft angle orientation and a lie angle orientation wherein all of the coupling positions have the same loft angle orientation.
7. The golf club of claim 6 , wherein the interchangeable shaft system is configured to provide at least four discrete orientations of the golf club head relative to the shaft within the lie plane so that a measured loft angle of the golf club is constant in the at least four discrete orientations.
8. The golf club of claim 6 , wherein the interchangeable shaft system includes a wedge member interposed between the shaft sleeve and the golf club head.
9. The golf club of claim 8 , wherein the wedge member is constructed to have two selectable orientations relative to the club head.
10. The golf club of claim 9 , wherein the shaft sleeve is constructed to have two selectable orientations relative to the wedge member.
11. A golf club, comprising:
a golf club head;
an elongate shaft; and
an interchangeable shaft system releasably coupling the shaft to the club head, the interchangeable shaft system comprising at least one wedge member and a shaft sleeve, wherein the wedge member is interposed between the shaft sleeve and a hosel of the golf club head, wherein the wedge member includes angled end surfaces, wherein the interchangeable shaft system includes a shaft sleeve assembly including a sleeve body and a tension member coupled to the sleeve body by a flexible coupling, and
wherein the interchangeable shaft system is configured to provide a plurality of coupling positions with each position producing a specific combination of a loft angle orientation and a lie angle orientation wherein all of the coupling positions have the same loft angle orientation.
12. The golf club of claim 11 , wherein the interchangeable shaft system is configured to provide at least four discrete orientations of the golf club head relative to the shaft within the lie plane so that a measured loft angle of the golf club is constant in the at least four discrete orientations.
13. The golf club of claim 11 , wherein the wedge member is constructed to have two selectable orientations relative to the club head.
14. The golf club of claim 11 , wherein the interchangeable shaft system includes a tubular wedge member slidably coupled to the shaft sleeve assembly and wherein the shaft sleeve assembly comprises means for capturing the wedge member on the shaft sleeve assembly.
