Abstract

A golf putter head includes a face member with a front surface arranged for impacting a golf ball. A first arm extends substantially rearwardly from a heel end of the face member, a second arm extends substantially rearwardly from a toe end of the face member, and a central member extends rearwardly from the face member intermediate the heel and toe ends thereof. The central member is connected to and extends rearwardly from a back surface of the face member. The central member is connected to the first and second arms rearwardly of the face member. The first and second arms have top surfaces that slope downwardly as the first and second arms extend away from the face member.

Claims

1. A golf putter head comprising:

a face member having a heel end, a toe end, a top rail extending between the heel and toe ends, a front surface arranged for impacting a golf ball, and a back surface;

a first arm extending generally rearwardly from the back surface of said face member at the heel end thereof;

a second arm extending generally rearwardly from the back surface of said face member at the toe end thereof;

a central member having an inner end connected to the back surface of said face member intermediate the heel and toe ends thereof, said central member extending rearwardly from said face member and being connected to said first and second arms rearwardly of said face member;

said central member and said first arm defining a first opening that extends through the golf putter head adjacent the heel end of said face member;

said central member and said second arm defining a second opening that extends through the golf putter head adjacent the toe end of said face member;

said central member including a first cavity in its upper surface located between said first and second openings; and

said central member further including a second cavity in its upper surface located rearwardly of said first cavity.

2. The golf putter head of claim 1, wherein said first and second arms are curved and wherein said central member is straight.

3. The golf putter of claim 1, further comprising a face plate disposed in the front surface of said face member.

4. The golf putter head of claim 1, further comprising a hosel disposed adjacent the heel end of said face member for receiving a shaft.

5. The golf putter head of claim 1, wherein the front and back surfaces of said face member arc substantially parallel to each other.

6. The golf putter head of claim 1, wherein said first and second arms have top surfaces that slope downwardly as said first and second arms extend away from said face member.

7. The golf putter head of claim 1, wherein said central member includes a pair of wing portions connecting said central member to said first and second arms.
