Abstract

A metal wood golf club head having a substantial portion of the mass of the club positioned near the front, striking face of the club head. A high density material, such as tungsten, is inlaid in the face section of the club head. The remaining, rear bulbous section is made of a lightweight, high strength material such as titanium.

Claims

1. An improved golf club head having a bulbous rear section, made of a synthetic material having a predetermine density, and the club head having an opposite face section including a first portion and a second portion, wherein the improvement comprises the second portion being made of a synthetic material having a density greater than the material of any part of the rear section and greater than a density of a synthetic material of the first portion of the face section, the second portion extending rearwardly at least from substantially a striking face plane.

2. A golf club head in accordance with claim 1, wherein the first portion of the face section is made of the same material as the rear section.

3. A golf club head in accordance with claim 1, wherein the second portion of the face section comprises the striking face.

4. A golf club head in accordance with claim 1, wherein the second portion of the face section comprises a band surrounding at least a portion of the striking face.

5. A golf club head in accordance with claim 2, wherein the second portion of the face section comprises a body mounted within a chamber formed in the club head.

6. A golf club head in accordance with claim 1, wherein the second portion of the face section further comprises the striking face and a band surrounding at least part of the striking face.

7. A golf club head in accordance with claim 2, wherein the material having greater density is metal.

8. A golf club head in accordance with claim 7, wherein the material of which the rear section is made is metal.

9. A golf club head in accordance with claim 7, wherein the metal is tungsten.

10. A golf club head in accordance with claim 1, wherein the synthetic material of the rear section, the synthetic material of the first portion of the face section, and the synthetic material of the second portion of the face section are metals.

11. A golf club head in accordance with claim 1, wherein the synthetic material of the rear section, the synthetic material of the first portion of the face section, and the synthetic material of the second portion of the face section are composites.

12. A golf club head in accordance with claim 1, wherein the synthetic material of the rear section, the synthetic material of the first portion of the face section, and the synthetic material of the second portion of the face section are made of metals and composites.

13. A golf club head having a front to rear thickness and a striking face including a first face portion and a second face portion, the club head also having a rear portion made of a synthetic material having a predetermined density, the rear portion including at least a rearwardmost three-quarters of the club head thickness, wherein a synthetic material of the first face portion has a predetermined density, and a synthetic material of the second face portion has a density greater than the material of the first face portion, and greater than the material of any part of the rear portion.

14. An improved golf club head in accordance with claim 13 wherein the second face portion comprises a band of greater density material attached within a groove formed around a peripheral edge of the striking face.

15. An improved golf club head in accordance with claim 13 wherein the second face portion comprises a plate of greater density material attached within a groove formed in a central region of the striking face.

16. An improved golf club head in accordance with claim 13 wherein the material of the second face portion is a metal.

17. An improved golf club head in accordance with claim 16 wherein the metal is tungsten.

18. A golf club head in accordance with claim 13, wherein the synthetic material of the rear section, the synthetic material of the first face portion, and the synthetic material of the second face portion are metals.

19. A golf club head in accordance with claim 13, wherein the synthetic material of the rear section, the synthetic material of the first face portion, and the synthetic material of the second face portion are composites.

20. A golf club head in accordance with claim 13, wherein the synthetic material of the rear section, the synthetic material of the first face portion, and the synthetic material of the second face portion are made of metals and composites.
