Abstract

A golf club head with improved striking face performance is disclosed herein. More specifically, the present invention discloses a golf club head having a thickened central region surrounded by an internal and an external transition region; wherein the thickened central region has an inner perimeter that takes on a shape that substantially resembles the shape of an outer perimeter of the striking face of the golf club head.

First claim

What is claimed is:

1. A golf club head having a crown, a sole, and a skirt comprising:
a striking face portion located at a frontal portion of said golf club head adapted to strike a golf ball, said striking face portion having a face perimeter; and
a body portion connected to an aft portion of said striking face portion;
wherein said striking face portion further comprises;
a thickened central portion having a central perimeter, and
a transition region having a transition perimeter,

wherein a total length of said central perimeter is greater than about 65 mm and less than about 80 mm; and
wherein said transition region creates a catenary curve near an upper portion of said striking face.

2. The golf club head of claim 1 , wherein said total length of said central perimeter is greater than about 70 mm and less than about 75 mm.

3. The golf club head of claim 2 , wherein said total length of said central perimeter is about 73 mm.

4. The golf club head of claim 1 , wherein a total length of said face perimeter is greater than about 250 mm and less than about 280 mm.

5. The golf club head of claim 4 , wherein said total length of said face perimeter is about 265 mm.

6. The golf club head of claim 1 , wherein said thickened central portion has a thickness of greater than about 3.0 mm.

7. The golf club head of claim 6 , wherein said thickened central portion has a thickness of greater than about 3.30 mm.

8. The golf club head of claim 7 , wherein said thickened central portion has a thickness of greater than about 3.60 mm.

9. A golf club head having a crown, a sole, and a skirt comprising:
a striking face portion located at a frontal portion of said golf club head adapted to strike a golf ball, said striking face portion having a face perimeter; and
a body portion connected to an aft portion of said striking face portion;
wherein said striking face portion further comprises;
a thickened region having a thickened region perimeter, and

wherein a total length of said thickened region perimeter is greater than about 65 mm and less than about 80 mm.

10. The golf club head of claim 9 , wherein said total length of said thickened region perimeter is greater than about 70 mm and less than about 75 mm.

11. The golf club head of claim 10 , wherein said total length of said thickened region perimeter is about 73 mm.

12. The golf club head of claim 9 , wherein said thickened region has a thickness of greater than about 3.0 mm.

13. The golf club head of claim 12 , wherein said thickened region has a thickness of greater than about 3.30 mm.

14. The golf club head of claim 13 , wherein said thickened region has a thickness of greater than about 3.60 mm.

15. The golf club head of claim 12 , wherein a size of a sweet spot of said striking face portion of said golf club head is greater than about 45 mm 2 ;
said sweet spot is defined as the area of said striking face portion that is capable of achieving 98% of a maximum ballspeed that can result from an impact with said golf ball.

16. The golf club head of claim 15 , wherein said size of said sweet spot is greater than about 46.5 mm 2 .

17. The golf club head of claim 16 , wherein said size of said sweet spot is greater than about 48 mm 2 .
