Abstract

A golf club includes a golf club head having a body defining an interior cavity. The body includes a sole, a crown and a skirt positioned around a periphery between the sole and crown. A face defines a forward portion of the club head and includes a striking surface width and a hosel defining a hosel bore. A channel and a recessed port are positioned in the sole. The channel extends substantially in a heel-to-toe direction. A sleeve is mounted on a tip end of the golf club shaft and is adapted to be inserted into the hosel bore. A fastener has a shaft portion extending through a passage and a head portion located in the recessed port. Selectively attaching the sleeve adjusts at least one of a loft angle and a lie angle of the club head.

Claims

1-21. -21. (canceled)

22. A golf club head, comprising:

a club head body defining an interior cavity, a sole defining a bottom portion of the club head, a crown defining a top portion of the club head, a face defining a forward portion of the club head and including a striking surface, and a rear portion opposite the face;

wherein the club head body has a head origin defined as a position on the striking surface at approximately a geometric center of the striking surface, the head origin including a head origin x-axis, a head origin y-axis, and a head origin z-axis;

wherein the head origin x-axis is tangential to the striking surface and generally parallel to a ground plane when the club head is in an address position, further wherein a positive x-axis extends towards a heel portion of the club head body;

wherein the head origin y-axis extends perpendicular to the head origin x-axis and generally parallel to the ground plane when the club head is in the address position, further wherein a positive y-axis extends rearward from the striking surface and through the rear portion of the club head body;

wherein the head origin z-axis extends perpendicular to the ground plane, and perpendicular to both the head origin x-axis and head origin y-axis when the club head is in the address position, further wherein a positive z-axis extends generally upward from the head origin; and

a plurality of weight ports positioned in the sole of the golf club head, comprising;

a first weight port configured to retain a first weight, the first weight port defining a first central axis that extends through the sole and the crown of the golf club head;

a second weight port configured to retain a second weight, the second weight port defining a second central axis that extends through the sole and the crown of the golf club head; and

a third weight port configured to retain a third weight, the third weight port defining a third central axis that extends through the sole and the crown of the golf club head;

wherein the first weight port is positioned a first distance from the head origin, the second weight port is positioned a second distance from the head origin, and the third weight port is positioned a third distance from the head origin; and

wherein, as measured along the head origin y-axis, the first distance is less than the second distance, and the first distance is also less than the third distance.

23. The golf club head of claim 22, wherein at least one of the plurality of weight ports is positioned within 30 mm of a nearest portion of a forward edge of the sole of the golf club head.

24. The golf club head of claim 23, wherein the first weight port, the second weight port, and the third weight port are approximately equally spaced apart from one another.

25. The golf club head of claim 23, wherein each of the first weight port, the second weight port, and the third weight port is positioned within 30 mm of a nearest portion of a forward edge of the sole of the golf club head.

26. The golf club head of claim 22, further comprising:

the first weight, the second weight, and the third weight are positioned within the first, second, and third weight ports, respectively, and the first, second, and third weight ports comprise internal threads that correspond to external threads formed on the first, second and third weights.

27. The golf club head of claim 22, further comprising:

the first weight, the second weight, and the third weight are positioned within the first, second, and third weight ports, respectively, and each of the first, second and third weights comprises a mass not exceeding 20 grams.

28. The golf club head of claim 27, wherein each of the first, second, and third weights has a mass of between 0.5 grams and 10 grams.

29. The golf club head of claim 27, wherein each of the first, second, and third weights comprises a tungsten weight.

30. The golf club head of claim 22, further comprising:

the first weight and the second weight are positioned within the first weight port and the second weight port, respectively, and the second weight has a mass that is different than the mass of the first weight.

31. The golf club head of claim 22, further comprising:

the first weight is positioned within the first weight port and has a center of gravity positioned forward of a midline of the golf club head.

32. The golf club head of claim 31, further comprising:

the second weight is positioned within the second weight port and has a center of gravity positioned rearward of a midline of the golf club head.

33. The golf club head of claim 32, wherein the second weight has a center of gravity that is within 40 mm of the rear of the golf club head.

34. The golf club head of claim 22, further comprising:

the first weight is positioned within the first weight port and has a center of gravity positioned rearward of a midline of the golf club head.

35. The golf club head of claim 31, wherein the golf club head has a front to back depth (D_ch) greater than 85 mm.

36. The golf club head of claim 31, wherein the golf club head has a height not exceeding 46 mm, and an above ground center-of-gravity location, Zup, not exceeding 19 mm;

wherein the face has a loft angle exceeding 13 degrees.

37. The golf club head of claim 36, wherein the golf club head has a center of gravity (CG) projection that is less than 3 mm from a center of a striking surface of the golf club head.

38. The golf club head of claim 37, wherein the face has a thickness not exceeding 2.3 mm.

39. The golf club head of claim 31, wherein the golf club head is at least partially comprised of a metal alloy, and further wherein the crown is at least partially comprised of a composite material.

40. The golf club head of claim 39, wherein the metal alloy comprises a titanium alloy.

41. The golf club head of claim 39, wherein the metal alloy comprises a steel alloy.

42. The golf club head of claim 31, further comprising a sleeve for securing a shaft to the golf club head.
