Golf club with improved performance characteristics
View Patent ↗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.
1. A metal wood type golf club comprising:
a shaft;
a grip connected to a proximal end of said shaft; and
a golf club head connected to a distal end of said shaft; wherein said club head further comprises;
a face portion providing a striking surface; and
a body portion extending from a rear section of said face portion including a crown portion and a sole portion,
wherein a total length of said shaft combined with said golf club head is between 41 inches to 45 inches;
wherein a maximum COR value of said head club head is between about 0.790 to about 0.830;
wherein said golf club head has a volume of between 200 cc to 300 cc;
wherein said golf club head has a loft angle β of between about 10 degrees and about 16 degrees;
wherein said golf club head has a geometric center of the face about 18 mm away from a ground, and
wherein said face depth height is between about 30 mm to about 65 mm.
2. The metal wood type golf club of claim 1 , wherein an MOI value about said y-axis is between about 2,500 g-cm 2 to about 4,500 g-cm 2 .
3. The metal wood type golf club of claim 1 , wherein said golf club head has a CG to face depth height ratio, defined by a height of a CG location of said golf club head divided by a face depth, of less than about 0.40.
4. The metal wood type golf club of claim 3 , wherein said CG location is located about 10 mm to about 20 mm above a ground plane.
5. The metal wood type golf club of claim 1 , wherein said face portion is made out of titanium.
6. The metal wood type golf club of claim 1 , wherein said golf club head has a performance factor of greater than about 2,900 g-cm 2 ; said performance factor defined as the product of said face depth height, a maximum COR value of said golf club head, and a MOI value of said golf club head about a y-axis, all divided by a height of said CG location.
7. 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.
8. The metal wood type golf club head of claim 7 , wherein said second radius of curvature is greater than 1.25 times of said first radius of curvature.
9. A metal wood type golf club comprising:
a shaft;
a grip connected to a proximal end of said shaft; and
a golf club head connected to a distal end of said shaft; wherein said club head further comprises;
a face portion providing a striking surface, defining a face depth height, for striking a golf ball; and
a body portion extending from a rear section of said face portion including a crown portion and a sole portion,
wherein a total length of said shaft combined with said golf club head is between 41 inches to 45 inches;
wherein said golf club head has a performance factor of greater than about 2,900 g-cm 2 ; said performance factor defined as the product of said face depth height, a maximum COR value of said golf club head, and a MOI value of said golf club head about a y-axis, all divided by a height of said CG location;
wherein said golf club head has a volume of between 200 cc to 300 cc; and
wherein said golf club head has a loft angle β of between about 10 degrees and about 16 degrees,
wherein said golf club head has a geometric center of the face about 18 mm away from a ground, and
wherein said face depth height is between about 30 mm to about 65 mm.
10. The metal wood type golf club of claim 9 , 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.
11. The metal wood type golf club of claim 10 , wherein said second radius of curvature is greater than 1.25 times of said first radius of curvature.
12. The metal wood type golf club of claim 9 , wherein said golf club head has a CG to face depth ratio, defined by a height of a CG location of said golf club head divided by said face depth height, of less than about 0.40.
13. The metal wood type golf club of claim 12 , wherein an MOI value about said y-axis is between about 2,500 g-cm 2 to about 4,500 g-cm 2 .
