Abstract

A golf club comprises a shaft, a club head, and a connection assembly that allows the shaft to be easily disconnected from the club head. In particular embodiments, a sleeve including a top portion, a middle portion connected to the top portion is described. The middle portion includes a thin wall thickness. A bottom portion is connected to the middle portion including a plurality of engaging surfaces. A central longitudinal axis and an offset angle offset from the central longitudinal axis is described. The offset angle allows a maximum loft change of about 0.5 degrees to about 4.0 degrees. The total weight of the sleeve is less than about 9 g.

Claims

1. A golf club head comprising:

a body including a face plate, a crown, a sole, and a hosel;

an adjustable head-shaft connection system configured to allow the golf club head to be adjustably attachable to a golf club shaft in a plurality of different positions resulting in different combinations of loft angle, face angle, and lie angle, the adjustable head-shaft connection system including a shaft sleeve having a weight of between about 4 g and about 9 g, wherein the shaft sleeve includes an upper portion configured to receive a distal end of a golf club shaft and a lower portion including a threaded bore adapted to receive a fastener to couple the shaft sleeve to the hosel, wherein the threaded bore is positioned below the distal end of the golf club shaft when the golf club shaft is received within the upper portion; and

at least two weights attachable to and removable from the body at a plurality of different positions relative to the body;

wherein a thickness of a thinnest portion of the face plate is at least 25% less than a thickness of a thickest portion of the face plate.

2. The golf club head of claim 1, wherein a maximum face plate thickness is greater than about 4.8 mm and a thinnest face plate thickness is less than about 2.3 mm.

3. The golf club head of claim 1, wherein at least a portion of the crown has an areal weight of less than about 0.36 g/cm².

4. A golf club head comprising:

a body including a face plate, a crown, a sole, and a hosel;

an adjustable head-shaft connection system configured to allow the golf club head to be adjustably attachable to a golf club shaft in a plurality of different positions resulting in different combinations of loft angle, face angle, and lie angle, the adjustable head-shaft connection system including a shaft sleeve having a weight of between about 4 g and about 9 g, wherein the shaft sleeve includes an upper portion configured to receive a distal end of a golf club shaft and a lower portion including a threaded bore adapted to receive a fastener to couple the shaft sleeve to the hosel, wherein the threaded bore is positioned below the distal end of the golf club shaft when the golf club shaft is received within the upper portion; and

at least two weights attachable to and removable from the body at a plurality of different positions relative to the body;

wherein the face plate includes a central portion, an intermediate portion surrounding the central portion, and an outer portion surrounding the intermediate portion, and the thickness of the intermediate portion is greater than the thickness of the outer portion.

5. The golf club head of claim 4, wherein the thickness of the intermediate portion is greater than the thickness of the central portion.

6. The golf club head of claim 4, wherein a thickness of a thinnest portion of the face plate is at least 25% less than a thickness of a thickest portion of the face plate.

7. The golf club head of claim 4, wherein a maximum face plate thickness is greater than about 4.8 mm and a thinnest face plate thickness is less than about 2.3 mm.

8. The golf club head of claim 4, wherein at least a portion of the crown has an areal weight of less than about 0.36 g/cm².

9. A golf club head comprising:

a body including a face plate, a crown, a sole, and a hosel;

an adjustable head-shaft connection system configured to allow the golf club head to be adjustably attachable to a golf club shaft in a plurality of different positions resulting in different combinations of loft angle, face angle, and lie angle, the adjustable head-shaft connection system including a shaft sleeve having a weight of between about 4 g and about 9 g, wherein the shaft sleeve includes an upper portion configured to receive a distal end of a golf club shaft and a lower portion including a threaded bore adapted to receive a fastener to couple the shaft sleeve to the hosel, wherein the threaded bore is positioned below the distal end of the golf club shaft when the golf club shaft is received within the upper portion; and

at least two weights attachable to and removable from the body at a plurality of different positions relative to the body.

10. The golf club head of claim 9, wherein a thickness of a thinnest portion of the face plate is at least 25% less than a thickness of a thickest portion of the face plate.

11. The golf club head of claim 9, wherein a maximum face plate thickness is greater than about 4.8 mm and a thinnest face plate thickness is less than about 2.3 mm.

12. The golf club head of claim 9, wherein the face plate comprises a central portion, an intermediate portion surrounding the central portion, and an outer portion surrounding the intermediate portion, and the thickness of the intermediate portion is greater than the thickness of the outer portion and the thickness of the central portion.

13. The golf club head of claim 9, wherein at least a portion of the crown has an areal weight of less than about 0.36 g/cm².
