Abstract
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.
Claims23
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 portion interconnecting said bottom edge of said leading section and said bottom edge of said trailing section;
- 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-cm2.
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 portion interconnecting said bottom edge of said leading section and said bottom edge of said trailing section;
- a heel portion and a toe portion disposed in the leading section, said heel portion and toe portion including a stepped down portion extending 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 extending between the leading and trailing sections, said web being disposed normal to the sole portion.
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 portion interconnecting said bottom edge of said leading section and said bottom edge of said trailing section;
- 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 extending between the leading and trailing sections, said web being disposed normal to the sole portion.
A golf club, comprising:
- a putter head including 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 shaft connected to the main body;
- a sole portion interconnecting said bottom edge of said leading section and said bottom edge of said trailing section;
- 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 5,500 grams-cm2.
