Abstract

A golf putter head includes an opening, a deflectable plate and a cutout. The opening is located behind a putter face, and is larger than a golf ball. The deflectable plate is coupled to the golf putter head, with a first end of the deflectable plate projecting into the opening. The cutout is located above the deflectable plate, the cutout having a width that is greater than or equal to a width of the deflectable plate.

Claims

1. A golf putter head comprising:

an opening located behind a putter face, the opening larger than a golf ball;

a deflectable plate coupled to the golf putter head, with a first end of the deflectable plate projecting into the opening; and

a cutout located above the deflectable plate, the cutout having a width that is greater than or equal to a width of the deflectable plate.

2. The golf putter head of claim 1, further comprising:

a support plate that couples the deflectable plate to a bottom surface of the golf putter head.

3. The golf putter head of claim 2, wherein a shape of a portion of the support plate conforms to a portion of the opening.

4. The golf putter head of claim 1, wherein the golf putter head is smaller than an inner diameter of a golf cup.

5. The golf putter head of claim 1, wherein the golf putter head includes a first and a second section, with each section extending from the putter face, and each section is cantilevered from the putter face thereby forming an aperture.

6. The golf putter head of claim 5, wherein a size of the aperture is smaller than a diameter of the opening.

7. The golf putter head of claim 5, wherein the size of the aperture is not less than 2.0 cm and not more than 3.0 cm.

8. The golf putter head of claim 1, wherein the deflectable plate is made of polyacetal resin or polypropylene.

9. The golf putter head of claim 1, wherein the opening is substantially circular, and a distance from the first end of the deflectable plate to an inner surface of the opening that is substantially opposite to the deflectable plate is not less than 38.8 mm and not more than 41.8 mm.

10. The golf putter head of claim 1, wherein the deflectable plate is located at a position other than the putter face.

11. A golf putter head comprising:

a face portion, a first weight portion that extends from a heel side of the face portion and a second weight portion that extends from a toe side of the putter face portion forming an area therebetween;

an deflectable tongue piece fixed to any one of the face portion, the first weight portion or the second weight portion, the deflectable tongue piece having an end that protrudes toward the area; and

a groove formed on an inner surface of any one of the face portion, the first weight portion or the second weight portion and formed above the deflectable tongue piece, the groove having a width that is greater than or equal to a width of the deflectable tongue piece;

wherein the area is sized to receive a golf ball.

12. The golf putter head of claim 11, further comprising:

a support plate that couples the deflectable tongue piece to a bottom surface of any one of the face portion, the first weight portion or the second weight portion.

13. The golf putter head of claim 12, wherein a shape of an end of the support plate is the same as a shape of a corresponding part of any one of the face portion, the first weight portion or the second weight portion.

14. The golf putter head of claim 11, wherein the golf putter head is smaller than an inner diameter of a golf cup.

15. The golf putter head of claim 11 wherein a distance between the first weight portion and the second weight portion reaches a minimum at a distal end of each of the first and second weight portions.

16. The golf putter head of claim 11, wherein the distance between the distal end of each of first weight portion and the second weight portions is not less than 2.0 cm and not more than 3.0 cm.

17. The golf putter head of claim 11, wherein the deflectable tongue piece is made of a polyacetal resin or polypropylene.

18. The golf putter head of claim 11, wherein the area is substantially circular, and a distance from the end of the deflectable tongue piece to an inner surface of any one of the face portion, the first weight portion or the second weight portion that is substantially opposite to the deflectable tongue piece is not less than 38.8 mm and not more than 41.8 mm.

19. The golf putter head of claim 11, wherein the deflectable tongue piece is coupled to the first weight portion or the second weight portion.
