Abstract

A golf club head comprising a body with a heel-side sole opening in communication with a hosel bore, a removable shaft sleeve with a tip sized to fit within the hosel bore, and a weight plug sized to fit within, and at least partially fill, the heel-side opening is disclosed herein. The weight plug, which has a base end with a through-opening, a tip end with a flange, and a side opening in communication with the through-opening, is connected to the shaft sleeve with a screw. When the golf club head is fully assembled, a hosel flange is trapped between the weight plug and the tip end of the shaft sleeve, and tightening the screw causes the weight plug and the shaft sleeve to move towards one another.

Claims

1. A golf club head comprising:

a body comprising a face portion, a sole portion, a crown portion, a heel side, a toe side, and a heel-side opening extending into the sole portion;

a hosel comprising a hosel bore and an internal hosel flange extending into and at least partially encircling the hosel bore;

a shaft sleeve comprising a shaft sleeve tip end with an internally threaded opening;

a first weight plug comprising a wall, a base end, a plug flange opposite the base end, a side opening extending into the wall proximate the plug flange, and a through-opening extending from the base end to the side opening;

a screw comprising a head portion, a midsection, and a threaded tip portion sized to engage the threads of the internally threaded opening in the shaft tip end; and

a washer disposed between the head portion of the screw and the plug flange,

wherein the heel-side opening communicates with the hosel bore,

wherein the first weight plug is sized to fit within the heel-side opening, and

wherein, when the first weight plug is disposed within the heel-side opening and the shaft sleeve is disposed within the hosel bore, the screw connects the weight plug to the shaft sleeve so that the internal hosel flange is sandwiched between the plug flange and the shaft tip end.

2. The golf club head of claim 1, wherein the plug flange is approximately U-shaped, wherein the head portion of the screw is disposed within the side opening of the first weight plug, and wherein the plug flange extends around a portion of the midsection of the screw.

3. The golf club head of claim 1, wherein the base end is angled with respect to the first weight plug wall, and wherein the first weight plug has a width that tapers from a maximum width proximate the base end to a minimum width proximate the plug flange.

4. The golf club head of claim 1, wherein the wall of the first weight plug has a varying thickness.

5. The golf club head of claim 1, wherein the body comprises a secondary weight port, wherein the secondary weight port is spaced from the heel-side opening, and wherein the first weight plug is sized to fit within the secondary weight port.

6. The golf club head of claim 5, wherein the golf club head further comprises a second weight plug, wherein the first weight plug has a first mass, wherein the second weight plug has a second mass that is different from the first mass.

7. The golf club head of claim 6, wherein each of the first and second weight plugs is sized to fit within the heel-side opening and the secondary weight port.

8. The golf club head of claim 5, wherein the secondary weight port extends into the toe side of the body.

9. The golf club head of claim 1, wherein the first weight plug has a mass of no more than 10 grams.

10. A golf club head comprising:

a body comprising;

a sole portion;

a crown portion;

a heel side;

a toe side;

a hollow interior cavity;

a hosel having a hosel bore and a hosel flange extending into the hosel bore; and

a heel-side opening extending into the sole portion in communication with the hosel bore;

a shaft sleeve comprising an internally threaded tip end, the tip end sized to fit within the hosel bore;

a weight plug comprising a wall, a base end, a u-shaped flange opposite the base end, a side opening extending into the wall proximate the u-shaped flange, and a through-opening extending from the base end to the side opening;

a screw comprising a head portion, an unthreaded midsection, and an externally threaded tip portion sized to engage the internally threaded tip end of the shaft sleeve; and

at least one washer,

wherein the weight plug is sized to fit within the heel-side opening,

wherein the weight plug has a width that tapers from a maximum width proximate the base end to a minimum width proximate the plug flange,

wherein the at least one washer at least partially encircles the unthreaded midsection of the screw,

wherein, when the weight plug is disposed within the heel-side opening and the tip end of the shaft sleeve is disposed within the hosel bore, the screw connects the weight plug to the shaft sleeve so that the hosel flange is disposed between the plug flange and the shaft tip end, and

wherein tightening the screw causes the weight plug and the shaft sleeve to move towards one another.

11. The golf club head of claim 10, wherein the shaft sleeve is composed of a first material, and wherein the weight plug is composed of a second material that differs from the first material.

12. The golf club head of claim 11, wherein the weight plug comprises a tungsten alloy.

13. The golf club head of claim 10, wherein the base end is approximately flush with an external surface of the sole portion.

14. The golf club head of claim 10, wherein the base end of the weight plug is painted to blend in with an external surface of the sole portion.

15. An assembly comprising:

a golf club shaft sleeve comprising a tip end having a threaded internal bore;

a weight plug comprising a wall, a base end, a u-shaped flange, a side opening, and a through opening extending from the base end to the flange and in communication with the side opening;

a screw comprising a head portion, an unthreaded midsection, and threaded tip portion;

at least one washer; and

at least one o-ring,

wherein the at least one washer and at least one o-ring at least partially encircle the unthreaded midsection,

wherein the head portion is disposed within the side opening so that the u-shaped flange extends around a portion of the unthreaded midsection,

wherein the threaded tip portion engages the threaded internal bore, and

wherein the screw reversibly attaches the weight plug to the shaft sleeve.

16. The assembly of claim 15, wherein the wall of the weight plug has a varying thickness.

17. The assembly of claim 15, wherein the golf club shaft sleeve is composed of a first material, and wherein the weight plug is composed of a second material that differs from the first material.

18. The assembly of claim 17, wherein the golf club shaft sleeve is composed of an aluminum alloy, and wherein the weight plug is composed of a titanium alloy.

19. The assembly of claim 15, wherein the weight plug comprises a tungsten alloy.

20. The assembly of claim 15, wherein the weight plug has a mass of no more than 10 grams.
