Golf club head with center of gravity adjustability
View Patent ↗The present invention is directed to a golf club head comprising one or more center of gravity and bias adjustment features. In some embodiments, the golf club head comprises an elongated cartridge having one or more sockets or weight ports to receive weight plugs, the arrangement of which can be changed to adjust the mass properties of the golf club head. The orientation of the cartridge itself can also be reversed to adjust the mass properties. In other embodiments, the golf club head comprises at least one semicircular weight ring that extends around the rear portion of the golf club head, and is removable and replaceable to adjust the mass properties of the golf club head. In still other embodiments, these features are combined on one head.
1. A golf club head comprising
a metal face component;
a composite body comprising a crown, a sole, an interior cavity, and a rear portion opposite the face;
a cartridge cap comprising a plurality of openings; and
at least one weight plug sized to fit within at least one of the plurality of openings,
wherein the rear portion comprises an opening in communication with the interior cavity,
wherein the cartridge cap is sized to fit over the rear portion such that an upper portion of the cartridge cap contacts the crown, a lower portion of the cartridge cap contacts the sole, and a middle portion of the cartridge cap is disposed within the opening, and
wherein reversing the orientation of the cartridge on the rear portion changes the location of the golf club head's center of gravity along a vertical Z axis.
2. The golf club head of claim 1 , further comprising at least one semicircular weight ring, wherein the at least one semicircular weight ring extends from a heel side of the face component to a toe side of the face component via the rear portion, and wherein the at least one semicircular weight ring is removably affixed to the body with at least one fastener.
3. The golf club head of claim 2 , wherein the at least one semicircular weight ring reversibly fixes the cartridge cap to the body.
4. The golf club head of claim 2 , wherein the cartridge cap is integrally formed with the at least one semicircular weight ring.
5. The golf club head of claim 2 , wherein the body comprises an elongated depression sized to receive the at least one semicircular weight ring.
6. The golf club head of claim 1 , wherein the crown comprises a first depression, wherein the sole comprises a second depression, wherein the upper portion is sized to fit within the first depression, and wherein the lower portion is sized to fit within the second depression.
7. The golf club head of claim 1 , wherein the at least one weight plug has a cylindrical shape.
8. The golf club head of claim 1 , wherein the at least one weight plug comprises a lightweight end and a heavy end.
9. The golf club head of claim 1 , wherein the plurality of openings comprises a first opening disposed in the upper portion, a second opening disposed in the lower portion, and a third opening disposed in the middle portion.
10. The golf club head of claim 1 , wherein the cartridge cap comprises a lightweight side and a heavy side.
