Abstract

A golf putter head with a heel end and a toe end includes a face member arranged for impacting a golf ball. A rear member extends in an arcuate path from one end of the face member to the other end of the face member. The face member and the rear member are made of a low density material such as carbon fiber. A first plurality of three weight members is disposed in the rear member, and each of these three weight members is each made of high density material, such as tungsten. A second plurality of two weight members is disposed in the face member, and each of these weight members is also made of high density material.

Claims

1. A golf putter head having a heel end and a toe end, said golf putter head comprising:

a face member including a front surface arranged for impacting a golf ball;

a rear member extending in an arcuate path from one end to the other end of said face member;

said face member and said rear member being made of low density material;

a first plurality of weight members disposed in said rear member, each weight member in said first plurality of weight members being made of high density material;

a second plurality of weight members disposed in said face member, each weight member in said second plurality of weight members also being made of high density material;

said second plurality of weight members including two weight members with one of the weight members located adjacent said one end of said face member and the other weight member located adjacent said other end of said face member.

2. The golf putter bead of claim 1, wherein said first plurality of weight members comprises three weight members with one weight member located adjacent said heel end, another weight member located adjacent said toe end, and a further weight member located intermediate said heel and toe ends.

3. The golf putter head of claim 1, wherein said low density material is a non-metallic material.

4. The golf putter head of claim 3, wherein said non-metallic material is carbon fiber.

5. The golf putter head of claim 4, wherein said high density material is a metallic material.

6. The golf putter head of claim 5, wherein said metallic material is tungsten.

7. The golf putter head of claim 1, wherein said arcuate path extends substantially 180 degrees.

8. The golf putter head of claim 1, further comprising first and second struts extending between and connected to said rear member and said face member, said first and second struts converging toward each other as they approach said face member.

9. The golf putter head of claim 8, further comprising a third strut extending between and connected to said rear member and said face member, said third strut lying between said first and second struts.

10. The golf putter head of claim 9, wherein said first, second and third struts are arranged to define four substantially trapezoid shaped open spaces between said face member and said rear member.

11. The golf putter head of claim 9, wherein said face member, said rear member, and said first, second and third struts in combination weigh approximately 190 grams.

12. The golf putter head of claim 11, wherein the three weight members of said plurality of weight members each weigh approximately 40 grams.

13. The golf putter head of claim 12, wherein the two weight members of said another plurality of weight members each weigh approximately 25 grams.

14. A golf putter head having a heel end and a toe end, said golf putter head comprising:

a face member including a front surface arranged for impacting a golf ball;

a rear member extending in an arcuate path from one end to the other end of said face member;

said face member and said rear member being made of low density material;

a first plurality of weight members disposed in said rear member and including one weight member located adjacent said heel end, another weight member located adjacent said toe end, and a further weight member located intermediate said heel and toe ends;

said weight members of said first plurality of weight members being made of high density material; and

a second plurality of weight members disposed in said face member, said second plurality of weight members including two weight members made of high density material with one of the weight members located adjacent said one end of said face member and the other weight member located adjacent said other end of said face member.

15. The golf putter head of claim 14, wherein said low density material is a non-metallic material and wherein said high density material is a metallic material.

16. The golf putter head of claim 15, wherein said non-metallic material is carbon fiber and wherein said metallic material is tungsten.

17. The golf putter head of claim 14, further comprising:

first and second struts extending between and connected to said rear member and said face member, said first and second struts converging toward each other as they approach said face member; and

a third strut extending between and connected to said rear member and said face member, said third strut lying between said first and second struts.
