Abstract

A golf putter with a having a curved body and a high toe design is disclosed and claimed. The putter head includes a face member, which has a heel and a toe, and a body member. The body member is connected to and extends rearward from the face member. At least a portion of the body member is curved toward the heel of the club head. The face member preferably is angled such that the toe has a greater height than the heel. The body member may be similarly angled. The body member extends through the face member and forms at least a portion of a striking face of the club head.

Claims (43)

1. A putter-type golf club head, comprising:

a face member having a heel and a toe; and

a body member coupled to said face member and comprising:

a straight portion extending rearward from a central portion of said face member intermediate said heel and said toe; and

a curved portion extending rearward from said straight portion and curved toward said heel,

wherein said curved portion has a radius of curvature from 0.5 inch to 10 inches.

2. The club head of claim 1 , wherein said radius of curvature is from 3 to 7 inches.

3. The club head of claim 1 , wherein said radius of curvature is constant through the entire curved portion.

4. The club head of claim 1 , wherein a first line perpendicular to said face member and a second line tangent to said curved body member portion at a rear-most end of said body member form an angle from 1° to 10°.

5. The club head of claim 4 , wherein said angle is from 3° to 7°.

6. The club head of claim 1 , wherein said straight portion extends a distance from 0.5 to 3 inches from said face member.

7. The club head of claim 1 , wherein an upper surface of said face member is angled such that said toe has a greater height than said heel.

8. The club head of claim 7 , wherein said upper surface forms a face member angle relative a horizontal plane at an address position from 1° to 10°.

9. The club head of claim 8 , wherein a first line perpendicular to said face member and a second line tangent to said curved body member portion at a rear-most end of said body member form a body member angle that is within one-half degree of said face member angle.

10. The club head of claim 9 , wherein the club head contains a loft angle that is within one-half degree of said body member angle and said face member angle.

11. The club head of claim 10 , further including a hosel coupled to said face member or said body member, said hosel forming and angle relative said face member that is within one-half degree of said loft angle, said body member angle, and said face member angle.

12. The club head of claim 8 , wherein at least a portion of said body member is tapered at an angle within one-half degree of said face member angle.

13. The club head of claim 1 , wherein said body member defines weight-reducing holes passing at least partially therethrough.

14. The club head of claim 1 , further including a weight member coupled to a rear portion of said body member.

15. The club head of claim 14 , wherein said weight member has a mass from 5 to 30 grams.

16. A putter-type golf club head comprising:

a face member having a heel and a toe; and

a body member coupled to said face member and comprising:

a straight portion extending rearward from said face member;

a curved portion curved toward said heel and extending rearward from said straight portion, wherein said curved portion comprises multiple radii of curvature, and wherein at least one radii of curvature is from 0.5 inch to 10 inches.

17. The putter-type golf club head of claim 16 , wherein an upper surface of said face member is angled such that said toe has a greater height than said heel.

18. A putter-type golf club head comprising:

a face member having a heel and a toe; and

a body member coupled to said face member and extending rearward from said face member, at least a portion of said body member being curved toward said heel;

wherein said body member extends through said face member and forms at least a portion of a striking face of the club head.

19. The putter-type golf club head of claim 18 , wherein an upper surface of said face member is angled such that said toe has a greater height than said heel.

20. A putter-type club head comprising:

a face member having a heel and a toe, wherein an upper surface of said face member is angled such that said toe has a greater height than said heel; and

a body member coupled to said face member and extending rearward from said face member, at least a portion of said body being curved toward the heel;

wherein said face member is formed of stainless steel and said body member is formed of aluminum or an aluminum alloy.

21. A putter-type golf club head comprising:

a face member having a heel and a toe; and

a body member coupled to said face member comprising:

a straight portion extending rearward from said face member; and

a curved portion, curved toward said heel and extending rearward from said straight portion,

wherein said face member includes one or more weight reducing recesses.

22. The putter-type golf club head of claim 21 , wherein an upper surface of said face member is angled such that said toe has a greater height than said heel.

23. The putter-type golf club head of claim 21 , wherein said curved portion has a radius of curvature from 0.5 inch to 10 inches.
