Abstract
A metal wood golf club head adapted for attachment to a shaft, comprising of a body portion and a crown portion, each portion constructed of a different density material. Combining a high-density material in the body portion, with a low-density material in the crown portion, creates an ultra-low center of gravity relative to the geometric face center, resulting in higher launch angles and spin rate ratios. The material for the crown portion is preferably a composite. A vibration dampening gasket is disposed between the ledge and lip sections of the body and crown respectively.
Claims19
A golf club head comprising:
- a face portion including an inner zone and an intermediate zone surrounding the inner zone, wherein the inner zone has a relatively high flexural stiffness such that a measurement zone, defined by a rectangle having the dimensions of 0.5 inch by 1.0 inch with a geometric center that coincides with a geometric center of the face portion, has a lowest COR that is at least 93 percent of a maximum COR;
- a body portion formed of a material having a first density;
- a crown portion formed of a second material having a second density that is less than the first density, such that the club head has a center of gravity that is lower than the geometric center of the face portion;
- and
- a dampening layer juxtaposed the body portion and the crown portion for acoustical attenuation between the frequencies of 3800 Hz and 10,000 Hz.
3 The golf club head of claim 1, wherein the center of gravity of the club head is positioned below the geometric center of the face by 0.05 inch to 0.15 inch.
A golf club comprising:
- a shaft;
- and
- a body portion coupled to the shaft and formed of a material having a first density, the body portion being comprised of a face portion including a measurement zone defined by a rectangle having the dimensions of 0.5 inch by 1.0 inch with a geometric center that coincides with a geometric center of the face portion and having a lowest COR that is at least 93 percent of a maximum COR;
- a crown portion formed of a second material having a second density that is less than the first density, such that the club head has a center of gravity that is lower than the geometric center of the face portion;
- and
- a dampening layer juxtaposed the body portion and the crown portion for acoustical attenuation between the frequencies of 3800 Hz and 10,000 Hz.
