View Patent ↗A golf club head is provided a weight system to adjust the center of gravity. In one embodiment, the weight system is a tube having a weight at one end that may be inserted into the golf club head to move the center of gravity at least forward and backward within 6 mm and up and down within 6 mm. Preferably, the tube is angled downward toward the face by at least 3 degrees. In another embodiment, the weight system may adjust the center of gravity of the golf club head along the x and z axis simultaneously using a weighted insert.
1. A golf club head comprising:
a body having a face, a sole, a crown, and a skirt joining the face, sole and crown, the body having a center of gravity;
the body having a coordinate system with an x-axis located horizontal to the club face, a y-axis located vertical to the club face, and a z-axis located through the club face, and
a weight system for the club head, wherein the center of gravity is adjustable along both the z-axis and the x-axis;
wherein the weight system further comprises;
a cavity and a weighted insert, wherein the weighted insert further comprises;
a heavy end at a first terminal end of the weighted insert,
a lighter end at a second terminal end of the weighted insert,
a central portion, placed between the heavy end and the lighter end of the weighted insert; and
a tube at least partially covering the weighted insert;
wherein the weighted insert further comprises a cap;
wherein the cap is removably attached to the weighted insert;
wherein the cap is adapted to be attachable to both the heavy end and the light end of the weighted insert; and
wherein the cap attaches to the weighted insert via a snap fit.
2. The golf club head of claim 1 , wherein the tube has an opening lengthwise along the entire length of the tube.
3. The golf club head of claim 1 , wherein the tube is threadably attached to the cavity of the golf club head.
4. A golf club head comprising:
a body having a face, a sole, a crown, and a skirt joining the face, sole and crown, the body having a center of gravity;
the body having a coordinate system with an x-axis located horizontal to the club face, a y-axis located vertical to the club face, and a z-axis located through the club face, and
a weight system for the club head, wherein the center of gravity is adjustable along both the z-axis and the x-axis;
wherein the weight system further comprises;
a cavity and a weighted insert, wherein the weighted insert further comprises;
a heavy end at a first terminal end of the weighted insert,
a lighter end at a second terminal end of the weighted insert,
a central portion, placed between the heavy end and the lighter end of the weighted insert; and
a cap adapted to be placed at both the heavy end and the lighter end of the weighted insert; and
wherein the cap attaches to the weighted insert via a snap fit.
5. The golf club head of claim 4 , wherein the cavity is offset from the x-axis at an angle θ of between about 0 and 90 degrees.
6. The golf club head of claim 5 , wherein the cavity is offset from the x-axis at an angle θ of between about 3 and 45 degrees.
7. The golf club head of claim 6 , wherein the cavity is offset from the x-axis at an angle θ of between about 5 to 35 degrees.
8. The golf club head of claim 5 , wherein the golf club head has an Angle to Volume Ratio of between about 0.02 degree/cc to about 0.25 degrees/cc;
the Angle to Volume Ratio is defined as the angle θ of the offset of the cavity from the x-axis divided by the volume of the golf club head.
9. The golf club head of claim 8 , wherein the golf club head has an Angle to Volume Ratio of between about 0.05 degrees/cc to about 0.255 degrees/cc.
10. The golf club head of claim 9 , wherein the golf club head has an Angle to Volume Ratio of between about 0.10 degrees/cc to about 0.20 degrees/cc.
