Abstract

A golf club head comprising a plurality of internal and/or external ribs are described herein. The golf club head comprises a ribbed region comprising at least a part of at least one of the heel portion, the toe portion, the sole, or the crown; wherein the ribbed region comprises a ribbed wall including: a ribbed wall interior surface, a ribbed wall exterior surface and one or more ribs protruding from the ribbed wall, wherein the one or more external ribs comprise a first rib including: a first rib exterior section and a first rib interior section, wherein the first rib interior section extends substantially parallel to the faceplate.

First claim

The invention claimed is:

1. A golf club head comprising:
a heel portion comprising a heel end;
a toe portion comprising a toe end;
a sole;
a crown;
a faceplate; wherein the faceplate is coupled to the sole and crown at a front end of the golf club head; and
a ribbed region comprising at least a part of the crown;
wherein the ribbed region comprises a ribbed wall comprising four external ribs protruding from the ribbed region;
wherein the four external ribs do not intersect each other within the ribbed region; and
wherein the four external ribs comprise rib axes that intersect to a common point external to the golf club head and forward of the faceplate; and
wherein the four external ribs further define five external thin portions within the ribbed region; and
wherein a thickness of the five external thin portions is approximately 0.43 mm;
wherein the ribbed region further comprises five internal ribs protruding from the ribbed region, wherein the five internal ribs extend from near the heel portion to near the toe portion of the golf club head;
wherein four of the five internal ribs are aligned with the four external ribs;
wherein the four aligned exterior and interior ribs are collinear to each other forming four ribs having an exterior section and an interior section;
wherein the exterior and interior sections of the four ribs extend an entire length of the ribbed region.

2. The golf club head of claim 1 , wherein the crown further comprises a front distance measured from the faceplate to a front edge of the ribbed region; and a rear distance measured from a rear perimeter of the golf club head to a rear edge of the ribbed region.

3. The golf club head of claim 2 , wherein the front distance varies in a range from 25 mm to 40 mm and wherein the front distance is greatest near the toe portion and the heel portion.

4. The golf club head of claim 2 , wherein the rear distance is constant.

5. The golf club head of claim 4 , wherein the rear distance is approximately 6.35 mm.

6. The golf club head of claim 1 , wherein the four external ribs further comprise an external rib height; and wherein the external rib height is approximately 0.255 mm.

7. The golf club head of claim 1 , wherein the four external ribs further comprise an external rib width; and wherein the external rib width tapers from approximately 4.00 mm near a front edge of the ribbed region to approximately 2.00 mm near a rear edge of the ribbed region.

8. The golf club head of claim 1 , wherein the five internal ribs extend beyond an internal thin portion of the ribbed region and into a perimeter of the golf club head.

9. The golf club head of claim 1 , wherein the five internal ribs are curved such that each end of the five internal ribs is positioned closer to a rear perimeter of the golf club head than a center of each of the five internal ribs.

10. A golf club head comprising:
a heel portion comprising a heel end;
a toe portion comprising a toe end;
a sole;
a crown;
a faceplate; wherein the faceplate is coupled to the sole and crown at a front end of the golf club head; and
a ribbed region comprising at least a part of the crown;
wherein the ribbed region comprises a ribbed wall comprising four external ribs protruding from the ribbed region;
wherein the four external ribs do not intersect each other within the ribbed region; and
wherein the four external ribs comprise rib axes that intersect to a common point external to the golf club head and forward of the faceplate; and
wherein the four external ribs further define five external thin portions, wherein a thickness of the five external thin portions is approximately 0.43 mm;
wherein the ribbed region further comprises five internal ribs protruding from the ribbed region;
wherein four of the five internal ribs extend from near a rear perimeter toward the faceplate;
and the four of the five internal ribs do not intersect each other; and
wherein a fifth internal rib is concave relative to the faceplate, and extends from near the heel portion toward near the toe portion;
wherein four of the five internal ribs are aligned with the four external ribs;
wherein the four aligned exterior and interior ribs are collinear to each other forming four ribs having an exterior section and an interior section;
wherein the exterior and interior sections of the four ribs extend an entire length of the ribbed region.

11. The golf club head of claim 10 , wherein the fifth internal rib intersects all of the other four internal ribs.

12. The golf club head of claim 11 , wherein the five internal ribs define ten internal thin portions.

13. The golf club head of claim 12 , wherein the ten internal thin portions comprise thicknesses of approximately 0.43 mm.

14. The golf club head of claim 10 , wherein the five internal ribs comprise an internal rib height of approximately 0.127 mm.

15. The golf club head of claim 10 , wherein the five internal ribs comprise an internal rib width of approximately 4.60 mm.

16. The golf club head of claim 10 , wherein the crown further comprises a front distance measured from the faceplate to a front edge of the ribbed region; and a rear distance measured from a rear perimeter of the golf club head to a rear edge of the ribbed region.

17. The golf club head of claim 16 , wherein the front distance varies in a range from 25 mm to 40 mm and wherein the front distance is greatest near the toe portion and the heel portion.

18. The golf club head of claim 16 , wherein the rear distance is constant.
