Abstract

A golf club head ( 40 ) with a face component ( 50 ), an aft body ( 70 ), and an aerodynamic hosel ( 50 ) is disclosed herein. The hosel ( 50 ) has one or more joints ( 80, 85, 87 ) around which pieces or segments of the hosel ( 50 ) may be rotated or pivoted to modify the way in which a shaft is oriented with respect to the club head ( 40 ) when the hosel ( 50 ) is rigidly affixed to the club head ( 40 ). The present invention may be used to modify the loft, lie, and/or face angle parameters of the golf club head.

Claims (18)

1. A golf club head comprising:

a face component, a crown, and a sole; and

a hosel comprising a shaft connection portion, a head connection portion, a first joint located between the shaft connection portion and the head connection portion, an intermediate segment, and a second joint disposed between the intermediate segment and the shaft connection portion,

wherein the intermediate segment is located between the first and second joints,

wherein the first joint allows the shaft connection portion and the intermediate segment to rotate with respect to the head connection portion, and

wherein the second joint is spaced from the first joint and allows the shaft connection portion to rotate with respect to, and independently of, the intermediate segment and the head connection portion.

2. The golf club head of claim 1 , wherein a cross-sectional shape of the hosel is selected from a group consisting of circular, elliptical, airfoil symmetrical, and non-uniform.

3. The golf club head of claim 2 , wherein at least part of the hosel has an airfoil cross-sectional shape.

4. The golf club head of claim 3 , wherein the part of the hosel having an airfoil cross-sectional shape has a length of 0.25 to 1.50 inches.

5. The golf club head of claim 4 , wherein the part of the hosel having an airfoil cross-sectional shape has a length that is less than or equal to 1.00 inch.

6. A golf club head comprising:

a face component, a crown, and a sole; and

a hosel comprising a head connection portion, a shaft connection portion, a first movable segment, and a second movable segment,

wherein the first movable segment is located between the shaft connection portion and the head connection portion,

wherein the second movable segment is located between the first movable segment and the head connection portion, and

wherein the entire first movable segment comprises a convex curvature.

7. The golf club head of claim 6 , wherein the first movable segment is pivotally attached to the shaft connection portion.

8. The golf club head of claim 6 , wherein the first movable segment is pivotally attached to the second movable segment.
