Abstract
A golf club head with an improved Center of Gravity (CG) location is disclosed. More specifically, the present invention relates to a metalwood type golf club head with improved performance via shifting the CG towards a location that reduces spin, at the same time, without sacrificing launch angle and the forgiveness of the golf club head. This golf club head may generally have a unique construction capable of achieving a low and forward CG location that is less than 40 mm from the face center along a Z-axis, a CG height that is no more than 2 mm above the neutral axis, and a MOI-Y of greater than about 4,000 g-cm2.
Claims19
A golf club head comprising:
- a striking face portion located at a frontal portion of said golf club head;
- a body portion, made out of a first material having a first density, attached to a rear of said striking face portion,
- wherein said striking face portion further comprising;
- an upper striking face portion located above a geometric center of said striking face portion, and
- a lower striking face portion located below said geometric center of said striking face portion,
- wherein at least a portion of said lower striking face portion further comprises a weighting mechanism,
- where said weighting mechanism encompasses a portion of a leading edge portion of said golf club head,
- wherein said golf club head has a CG-Z-FC less than about 40 mm from a face center,
- wherein said golf club head has a CG-NA of less than about 2 mm above a neutral axis, and
- wherein said golf club head has a MOI-Y of greater than about 4,000 g-cm2.
A golf club head comprising:
- a striking face portion located at a frontal portion of said golf club head;
- a body portion, made out of a first material having a first density, attached to a rear of said striking face portion,
- wherein said striking face portion further comprising;
- an upper striking face portion located above a geometric center of said striking face portion, and
- a lower striking face portion located below said geometric center of said striking face portion,
- wherein at least a portion of said lower striking face portion further comprises a weighting mechanism further comprising;
- a high density member, made out of a second material having a second density, and
- an attachment member, adapted to engage an opening in said high density member,
- wherein said second density is greater than said first density,
- wherein said attachment member secures said high density member to a leading edge portion of said golf club head, and
- where said weighting mechanism encompasses a portion of said leading edge portion of said golf club head,
- wherein said leading edge portion further comprises;
- a chamfered leading edge,
- wherein said chamfered leading edge has a chamfer angle of between about 60 degrees to about 70 degrees,
- wherein said chamfered leading edge combined with said weighting mechanism to form said leading edge of said golf club head.
