Title: Golf club head with twisted face angle

Brief Patent Description - Full Patent Description - Patent Claims

The Patent Description & Claims data below is from USPTO Patent Application 20070275791, Golf club head with twisted face angle.

1. A golf club head comprising:a front face that is defined by a first horizontal plane through the center of the face and having a first tangent at an intersection between the first horizontal plane and a center vertical plane; anda second horizontal plane located a distance between the first horizontal plane and a top line,wherein the second horizontal plane has a second tangent at an intersection between the second horizontal plane and the center vertical plane that is at an angle to the first tangent.

2. The golf club head of claim 1, wherein the second tangent is at an angle of between 0.05.degree. and 2.0.degree. to the first tangent in an open direction.

3. The golf club head of claim 1, wherein the club head further comprises:a third horizontal plane located a distance between the first horizontal plane and a bottom line,wherein the third horizontal plane has a third tangent at an intersection between the third horizontal plane and the center vertical plane that is at an angle to the first tangent.

4. The golf club head of claim 3, wherein the third tangent is at an angle of between 0.05.degree. and 2.0.degree. to the first tangent in a closed direction.

5. The golf club head of claim 3, wherein the second and third tangents are at angles to the first tangent selectively based upon a user's swing speed.

6. The golf club head of claim 3, wherein the second and third horizontal planes are at a distance of at least about 0.5 inch from the first horizontal plane.

7. A golf club head comprising:a front face that is defined by a first horizontal plane through the center of the face and having a first tangent at an intersection between the first horizontal plane and a center vertical plane;a second horizontal plane located a distance between the first horizontal plane and a top line;a third horizontal plane located a distance between the first horizontal plane and a bottom line;wherein the second horizontal plane has a second tangent at an intersection between the second horizontal plane and the center vertical plane that is an angle to the first tangent and the third horizontal plane has a third tangent at an intersection between the third horizontal plane and the center vertical plane that is an angle to the first tangent.

8. The golf club head of claim 7, wherein the second and third tangents are each at angles of between 0.05.degree. and 2.0.degree. to the first tangent.

9. The golf club head of claim 7, wherein the second and third tangents are at angles to the first tangent selectively based upon a user's swing speed.

10. The golf club head of claim 7, wherein the second tangent extends into an upper toe quadrant of the front face and the third tangent extends into a lower heel quadrant of the front face,wherein the front face is caused to have a twist extending along the center vertical plane.

11. The golf club head of claim 7, wherein the second and third horizontal planes are at a distance of about 0.5 inch from the first horizontal plane.

12. A method for fitting a player to a golf club based on player's swing speed defined by selecting optimal bulge radii and roll radii for the player's swing speed.

13. A golf club head comprising: a front face having a face angle that is twisted from high to low, wherein the face angle high on the face is open relative to the face angle at the center of the face, and the face angle low on the face is closed relative to the face angle at the center of the face.

14. The golf club head of claim 13, wherein the face angle high on the face is at an angle of between 0.05.degree. and 2.0.degree. to the angle at the center of the face in an open direction.

15. The golf club head of claim 13, wherein the face angle low on the face is at an angle of between 0.05.degree. and 2.0.degree. to the angle at the center of the face in a closed direction.

16. The golf club head of claim 13, wherein the face angles high and low on the face are at angles to the center of the face selectively based upon a user's swing speed.

17. The golf club head of claim 13, wherein the face angle high on the face is at a distance of at least about 0.5 inch from the center of the face.

18. The golf club head of claim 13, wherein the face angle low on the face is at a distance of at least about 0.5 inch from the center of the face.
