Golf club head
View Patent ↗A golf club head, particularly for putting, includes a main body having a leading section and a trailing section where the leading section has a top edge and a bottom edge and the trailing section has a top edge and a bottom edge. A sole portion interconnects the bottom edge of the leading section and the bottom edge of the trailing section. A heel portion and a toe portion each include a weight disposed therein. In addition, a third weight is disposed in the trailing section of the club. The weighting is such that the moment of inertia of the club head is increased over known putters.
1. A golf putter head, comprising:
a main body having a leading section and a trailing section, said leading section having a top edge and a bottom edge and said trailing section having a top edge and a bottom edge;
a sole plate interconnecting only said bottom edge of said leading section and said bottom edge of said trailing section such that a void is defined between said leading section and said trailing section in a longitudinal direction;
a web disposed centrally within the void so as to bifurcate the same and further interconnecting said leading and trailing sections, said web being disposed normal to the sole plate and including a sighting line disposed thereon;
a heel portion and a toe portion disposed in the leading section;
a first weight-receiving cavity formed in said heel portion;
a first weight positioned within said first weight-receiving cavity;
a second weight-receiving cavity formed in said toe portion;
a second weight positioned within said second weight-receiving cavity;
a third weight-receiving cavity formed in said trailing section;
a third weight positioned within said third weight-receiving cavity;
whereby a ratio of the weight of the third weight to the combined weight of the first and second weights is such that the moment of inertia of the putter head is at least 5,000 grams-cm 2 .
2. The golf putter head of claim 1 , wherein a center of gravity is closer to the leading section than the trailing section.
3. The golf putter head of claim 1 , wherein the first and second weights weigh approximately 15 grams each and the third weight weighs approximately 130 grams.
4. The golf putter head of claim 1 , wherein the third weight extends substantially through the trailing section.
5. The golf putter head of claim 1 , wherein the ratio of the weight of the third weight to the combined weight of the first and second weights is at least 4 to 1.
6. The golf putter head of claim 1 , wherein the moment of inertia is greater than 5500 grams-cm 2 .
7. A golf putter head, comprising:
a main body having a leading section and a trailing section, said leading section having a top edge and a bottom edge and said trailing section having a top edge and a bottom edge;
a sole interconnecting only said bottom edge of said leading section and said bottom edge of said trailing section such that a void is defined between said leading section and said trailing section in a longitudinal direction;
a heel portion and a toe portion disposed in the leading section, said heel portion and toe portion including a stepped down portion extending within the void from the leading section to the trailing section;
a first weight-receiving cavity formed in said heel portion;
a first weight positioned within said first weight-receiving cavity;
a second weight-receiving cavity formed in said toe portion;
a second weight positioned within said second weight-receiving cavity;
a third weight-receiving cavity formed in said trailing section;
a third weight positioned within said third weight-receiving cavity; and
a web disposed within said void so as to bifurcate the same, said web extending between the leading and trailing sections, said web being disposed normal to the sole plate.
8. The golf putter head of claim 7 , wherein a ratio of the weight of the third weight to the combined weight of the first and second weights is such that the moment of inertia of the putter head is at least 5,000 grams-cm 2 .
9. The golf putter head of claim 7 , wherein said web includes a sighting line disposed thereon.
10. The golf putter head of claim 7 , wherein the first and second weights weigh approximately 15 grams each and the third weight weighs approximately 130 grams.
11. The golf putter head of claim 7 , wherein the ratio of the weight of the third weight to the combined weight of the first and second weights is at least 4 to 1.
12. The golf putter head of claim 7 , wherein the moment of inertia is greater than 5500 grams-cm 2 .
13. The golf putter head of claim 7 , wherein the third weight extends substantially through the trailing section.
14. The golf putter head of claim 7 , wherein a center of gravity is closer to the leading section than the trailing section.
15. The golf putter head of claim 7 , wherein the ratio of the weight of the third weight to the combined weight of the first and second weights is at least 4 to 1.
16. The golf putter head of claim 7 , wherein the moment of inertia is greater than 5500 grams-cm 2 .
17. The golf putter head of claim 7 , wherein a center of gravity is closer to the leading section than the trailing section.
18. A golf putter head, comprising:
a main body having a leading section and a trailing section, said leading section having a top edge and a bottom edge and said trailing section having a top edge and a bottom edge;
a sole plate interconnecting only said bottom edge of said leading section and said bottom edge of said trailing section such that a void is defined between said leading section and said trailing section in a longitudinal direction;
a heel portion and a toe portion disposed in said leading section;
a first weight-receiving cavity formed in said heel portion;
a first weight positioned within said first weight-receiving cavity;
a second weight-receiving cavity formed in said toe portion;
a second weight positioned within said second weight-receiving cavity;
a third weight-receiving cavity formed in said trailing section;
a third weight positioned within said third weight-receiving cavity and extending substantially through the trailing section, said leading section and said trailing section having substantially the same depth; and
a web disposed within said void so as to bifurcate the same, said web extending between the leading and trailing sections, said web being disposed normal to the sole plate.
19. The golf putter head of claim 18 , wherein a ratio of the weight of the third weight to the combined weight of the first and second weights is such that the moment of inertia of the putter head is at least 5,000 grams-cm 2 .
20. The golf putter head of claim 18 , wherein said web includes a sighting line disposed thereon.
21. The golf putter head of claim 18 , wherein the first and second weights weigh approximately 15 grams each and the third weight weighs approximately 130 grams.
