Abstract

A hybrid type golf club head is disclosed herein. The hybrid golf club head preferably has an increased heel/toe camber to minimize drag through rough when a golfer swings the hybrid golf club. A sole of the hybrid golf club head is relieved to allow for the face angle to open without the leading edge lifting too high.

Claims

1. A hybrid golf club head comprising:

a body comprising a crown section, a sole section and a face section;

wherein the sole section is relieved to allow for a face angle to open without a leading edge lifting too high.

2. The hybrid golf club head according to claim 1 wherein the face section has a plurality of scorelines, and at least one of the plurality of scorelines is placed high on the face section.

3. The hybrid golf club head according to claim 1 wherein the body has an increased heel/toe camber to minimize drag through rough during a golf swing.

4. The hybrid golf club head according to claim 1 wherein the body has a forward center of gravity.

5. The hybrid golf club head according to claim 1 wherein a mass is placed rearward on an interior of the sole section to increase a moment of inertia of the body.

6. The hybrid golf club head according to claim 1 wherein the body is composed of a stainless steel material.

7. The hybrid golf club head according to claim 1 wherein the body is composed of a titanium alloy material.

8. The hybrid golf club head according to claim 1 wherein the hybrid golf club head has a loft angle ranging from 18 degrees to 28 degrees.

9. The hybrid golf club head according to claim 1 wherein the hybrid golf club head has a volume less than 200 cubic centimeters.

10. The hybrid golf club head according to claim 1 wherein the hybrid golf club head has a volume ranging from 50 to 150 cubic centimeters.

11. The hybrid golf club head according to claim 1 wherein the hybrid golf club head has a volume ranging from 60 to 100 cubic centimeters.

12. The hybrid golf club head according to claim 1 wherein the hybrid golf club head has a volume ranging from 70 to 90 cubic centimeters.

13. The hybrid golf club head according to claim 1 wherein the hybrid golf club head has a mass ranging from 210 grams to 240 grams.

14. The hybrid golf club head according to claim 1 wherein the hybrid golf club head has a moment of inertia Izz about a center of gravity ranging from 2000 to 3000 grams-centimeters squared.

15. The hybrid golf club head according to claim 1 wherein the hybrid golf club head has a moment of inertia Izz about a center of gravity ranging from 2300 to 2700 grams-centimeters squared.

16. The hybrid golf club head according to claim 1 wherein the hybrid golf club head has a moment of inertia Ixx about a center of gravity ranging from 1900 to 2500 grams-centimeters squared.

17. The hybrid golf club head according to claim 1 wherein the hybrid golf club head has a moment of inertia Ixx about a center of gravity ranging from 2100 to 2300 grams-centimeters squared.

19. The hybrid golf club head according to claim 1 wherein the face section comprises a plurality of scorelines having V-shaped grooves.

18. A hybrid golf club head comprising:

a body comprising a crown section, a sole section and a face section, the body composed of a stainless steel material;

wherein the hybrid golf club head has a volume ranging from 70 to 90 cubic centimeters;

wherein the hybrid golf club head has a mass ranging from 210 grams to 240 grams;

wherein the hybrid golf club head has a loft angle ranging from 18 degrees to 28 degrees;

wherein the hybrid golf club head has a moment of inertia Izz about a center of gravity ranging from 2300 to 2700 grams-centimeters squared and a moment of inertia Ixx about a center of gravity ranging from 1900 to 2500 grams-centimeters squared;

wherein a center of gravity of the hybrid golf club head is forward of a hosel of the hybrid golf club head.
