Abstract

A metal wood type golf club with improved performance characteristics is disclosed herein where the metal wood type golf club head will combined the performance characteristics of both a driver type golf club head and a fairway type golf club head. More specifically, the present invention relates to a golf club head with a volume of between about 150 cc to about 360 cc, a CG location between about 10 mm to about 20 mm above the ground, a face depth of between about 30 millimeters (mm) to about 65 millimeters (mm), a loft of about between 10 degrees to about 16 degrees, and a COR of about 0.790 to about 0.830, wherein the entire golf club has a length of between about 41 inches to about 45 inches.

First claim

What is claimed is:

1. A metal wood type golf club comprising:
a shaft;
a grip connected to a proximal end of the shaft;
a metal wood type golf club head connected to a distal end of said shaft; wherein said head further comprises
a face portion providing a striking surface having a measurable face depth height for striking a golf ball
a body portion extending from a rear section of said face portion including a crown portion and a sole portion,
wherein said metalwood type golf club head has a volume of between 200 cc to 300 cc,

wherein a total club length of said shaft combined with said metal wood type golf club head is between 41 inches to 45 inches,
wherein a COR value of said head of said metal wood type golf club head is between about 0.790 to about 0.830,
wherein a MOI value about a y-axis is between about 2,500 g-cm 2 to about 4,500 g-cm 2 , and
wherein said metal wood type golf club head has a face depth height of between about 30 mm to about 65 mm, and
wherein a MOI value about a shaft axis is between about 3,000 g-cm 2 to about 6,000 g-cm 2 .

2. The metal wood type golf club of claim 1 , wherein a CG location of said metal wood type golf club head is located about 10 mm to about 20 mm above a ground plane.

3. The metal wood type golf club of claim 1 , wherein said face portion further comprises;
a top portion containing a first radius of curvature; and
a bottom portion containing a second radius of curvature;
wherein said second radius of curvature is greater than said first radius of curvature.

4. The metal wood type golf club of claim 3 , wherein said second radius of curvature is greater than 1.25 times of said first radius of curvature.

5. The metal wood type golf club of claim 4 , wherein said second radius of curvature is greater than 1.5 times of said first radius of curvature.

6. The metal wood type golf club of claim 5 , wherein said second radius of curvature is greater than 2.0 times of said first radius of curvature.

7. The metal wood type golf club head of claim 3 , wherein said first radius of curvature is between about 11 degrees to about 13 degrees.

8. The metal wood type golf club head of claim 7 , wherein said second radius of curvature is greater than about 15 degrees.

9. A metal wood type golf club head comprising:
a shaft;
a grip connected to a proximal end of the shaft;
a metal wood type golf club head connected to a distal end of said shaft; wherein said head further comprises
a face portion providing a striking surface having a measurable face depth height for striking a golf ball
a body portion extending from a rear section of said face portion including a crown portion and a sole portion,
wherein said metalwood type golf club head has a volume of between 200 cc to 300 cc,

wherein a total club length of said shaft combined with said metal wood type golf club head is between 41 inches to 45 inches,
wherein a COR value of said head of said metal wood type golf club head is between about 0.790 to about 0.830, and
wherein said face portion further comprises;
a top portion containing a first radius of curvature; and
a bottom portion containing a second radius of curvature;
wherein said second radius of curvature is greater than said first radius of curvature,
wherein said first radius of curvature is between about 11 degrees to about 13 degrees.

10. The metal wood type golf club of claim 9 , wherein said second radius of curvature is greater than 1.25 times of said first radius of curvature.

11. The metal wood type golf club of claim 10 , wherein said second radius of curvature is greater than 1.5 times of said first radius of curvature.

12. The metal wood type golf club of claim 11 , wherein said second radius of curvature is greater than 2.0 times of said first radius of curvature.

13. The metal wood type golf club head of claim 10 , wherein said second radius of curvature is greater than about 15 degrees.
