Abstract

A golf club includes a striking face, a top portion, a sole portion opposite the top portion, and a shaft assembly. The shaft assembly can include a shaft having a butt end and a tip end, and a shaft sleeve located at the tip end, the shaft sleeve including indicia. The golf club may further include a hosel extending from the top portion, and the hosel can include a sidewall, a tip end, an internal bore for receiving the shaft assembly, a hosel axis, and an aperture extending through, and circumscribed by, the sidewall such that the indicia of the shaft sleeve corresponds with the aperture. The sidewall circumscribing the aperture may include an inner surface having a first thickness T 1 in a radial direction relative the hosel axis and a chamfered edge having a second thickness T 2 in the radial direction, T 1 /T 2 being between approximately 3 and 7.33.

First claim

What is claimed is:

1 . A golf club comprising:
a striking face; a top portion; a sole portion opposite the top portion; a shaft assembly including a shaft having a butt end and a tip end, and a shaft sleeve located at the tip end, the shaft sleeve including indicia; and a hosel extending from the top portion, the hosel including a sidewall, a tip end, an internal bore for receiving the shaft assembly, a hosel axis, and an aperture extending through, and circumscribed by, the sidewall such that the indicia of the shaft sleeve corresponds with the aperture, wherein the sidewall circumscribing the aperture includes an inner surface having a first thickness T 1 in a radial direction relative the hosel axis and a chamfered edge having a second thickness T 2 in the radial direction, T 1 /T 2 being between approximately 3 and 7.33.

2 . The golf club of claim 1 wherein the aperture has a length less than 22 mm.

3 . The golf club of claim 1 , wherein the aperture has a width greater than or equal to 2 mm and less than 4 mm.

4 . The golf club of claim 1 , wherein the aperture has a top portion and a bottom portion such that at least one of the top portion and the bottom portion, in its entirety, follows a semi-circular path.

5 . The golf club of claim 1 , wherein the chamfered edge extends outward of the inner surface to form an interior angle therebetween of between about 110° and 160°.

6 . The golf club of claim 1 , wherein the aperture is elongated in a direction along the hosel axis.

7 . The golf club of claim 1 , wherein the aperture has an average thickness no greater than 2.5 mm.

8 . A golf club head comprising:
a striking face; a top portion; a sole portion opposite the top portion; and a hosel extending from the top portion, the hosel including a sidewall, a tip end, an internal bore configured to secure a shaft assembly to the golf club head, a hosel axis, and an aperture extending through, and circumscribed by, the sidewall, wherein the sidewall circumscribing the aperture includes an inner surface having a first thickness T 1 in a radial direction from the hosel axis and a chamfered edge having a second thickness T 2 in the radial direction, T 1 /T 2 being between approximately 3 and 7.33.

9 . The golf club of claim 8 , wherein the aperture has a width greater than or equal to 2 mm and less than 4 mm.

10 . The golf club of claim 8 , wherein the aperture has a top portion and a bottom portion such that at least one of the top portion and the bottom portion, in its entirety, follows a semi-circular path.

11 . The golf club of claim 8 , wherein the chamfered edge extends outward of the inner surface to form an interior angle therebetween of between about 110° and 160°.

12 . The golf club head of claim 8 , wherein the hosel further comprises a throughbore communicating with the internal bore and a bottom surface of the sole portion for accepting a securing member to secure the shaft assembly to the hosel.

13 . The golf club head of claim 8 , wherein the hosel further includes an exterior surface comprising a threaded portion for association with the securing member.

14 . The golf club head of claim 8 , wherein the hosel further comprises a rotation-inhibiting element.

15 . The golf club head of claim 14 , wherein the rotation-inhibiting element comprises a plurality of grooves elongate in a direction along the hosel axis.

16 . The golf club head of claim 14 , wherein the rotation-inhibiting element comprises a plurality of notches that extend downward from the tip end of the hosel.

17 . The golf club head of claim 8 , wherein the aperture is elongate in a direction along the hosel axis.

18 . The golf club head of claim 8 , wherein the aperture has a length less than 22 mm.

19 . The golf club head of claim 8 , wherein the aperture includes an uppermost point located on a first plane perpendicular to the hosel axis, and the hosel includes an uppermost point located on a second plane, the first plane being parallel to the second plane and separated from the second plane by at least 1 mm, and upward being a direction along the hosel axis toward the tip end of the hosel from the sole portion.

20 . The golf club head of claim 8 , wherein the aperture has an average thickness no greater than 2.5 mm.
