Abstract

A golf club head includes a face portion and a major body portion to which the face portion is connected. The surface area of the major portion has a plurality of space indentations, such as dimples, over the entire surface area.

Claims

1. A golf club head comprising:

a face portion;

a body portion to which the face portion is connected and said body portion including a surface portion other than the face portion having a plurality of spaced indentations, wherein the golf club head has an axis centered around a center of mass, the axis having a first coordinate that is normal to the face portion and a second coordinate that is in parallel alignment with the face portion, the plurality of spaced indentations being aligned in a pattern that is in parallel alignment with the face portion, the first coordinate and the second coordinate and no member of the plurality or spaced indentations coincides with the first and second coordinate.

2. The golf club head according to claim 1 wherein each indentation has a diameter and a depth and wherein the depth has a range of 3% to 8% of the diameter of the indentation.

3. The golf club head according to claim 1 wherein the golf club head comprises:

a top portion connected to the face portion on a top end at a first boundary;

a bottom portion connected to the face portion on a bottom end at a second boundary;

a side portion being connected to the face portion on a first side end at a third boundary and on a second side end at a fourth boundary and also being connected to the bottom portion at a fifth boundary and to the top portion at a sixth boundary; and

wherein no single member of the plurality of indentations is coincidental with the first, second, third, fourth, fifth and sixth boundaries.

4. The golf club head according to claim 3 wherein the pattern further comprises an arrangement of the indentations such that there are no bald spots on the top, bottom or side portions.

5. The golf club head according to claim 3 wherein the indentations are dimples and the pattern includes dimples having varying sizes in diameter.

6. The golf club head according to claim 1 wherein each indentation is shaped as a dimple.

7. The golf club head according to claim 1 wherein each indentation is shaped as a triangle.

8. The golf club head according to claim 7 wherein each triangle shaped indentation has a depth that falls within a range of between 6% and 16% of an axis of the triangle.

9. The golf club head according to claim 1 further including a shaft connected to golf club head and on the opposite end of the shaft away from the golf club head is a grip.

10. A golf club head having a shaft connected on one end and a grip connected on the end of the shaft opposite the golf club head, the golf club head comprising:

a face portion;

a body portion to which the face portion is connected and said body portion including a surface portion other than the face portion having a plurality of spaced indentations wherein the golf club head has an axis centered around a center of mass, the axis having a first coordinate that is normal to the face portion and a second coordinate that is in parallel alignment with the face portion, the plurality of spaced indentations being aligned in a pattern that is in parallel alignment with the face portion, the first coordinate and the second coordinate and no member of the plurality of spaced indentations coincides with the first and second coordinate.

11. The golf club head according to claim 10 wherein each indentation has a diameter and a depth and wherein the depth has a range of 3% to 8% of the diameter of the indentation.

12. The golf club head according to claim 10 wherein the golf club head comprises:

a top portion connected to the face portion on a top end at a first boundary;

a bottom portion connected to the face portion on a bottom end at a second boundary;

a side portion being connected to the face portion on a first side end at a third boundary and on a second side end at a fourth boundary and also being connected to the bottom portion at a fifth boundary and to the top portion at a sixth boundary; and

wherein no single member of the plurality of indentations is coincidental with the first, second, third, fourth, fifth and sixth boundaries.

13. The golf club head according to claim 12 wherein the pattern further comprises an arrangement of the indentations such that there are no bald spots on the top, bottom or side portions.

14. The golf club head according to claim 12 wherein the indentations are dimples and the pattern includes dimples having varying sizes in diameter.

15. The golf club head according to claim 10 wherein each indentation is shaped as a dimple.

16. The golf club head according to claim 10 wherein each indentation is shaped as a triangle.

17. The golf club head according to claim 16 wherein each triangle shaped indentation has a depth that falls within a range of between 6% and 16% of an axis of the triangle.
