Golf club head with vertical center of gravity adjustment

摘要

Golf club heads include at least one weight port situated to retain weights and positioned above an approximate club face geometric center with the club in a standard address position. One, two, or more weight ports can be located above the club face center in a club crown or other portion of a club body. Club head vertical center of gravity can be selected to compensate dynamic loft associated with locating the club head center of gravity well behind the club face. Three-dimensional adjustment of club head center of gravity is possible.

主权项

1. A wood-type golf club head comprising:
a body comprising a face positioned at a forward portion of the golf club head, a sole positioned at a bottom portion of the golf club head, a crown positioned at a top portion of the golf club head and a skirt positioned around a periphery of the golf club head between the sole and crown, wherein the body defines an interior cavity; wherein the head has a face center of the face at an approximate geometric center of the face, the face including an x-axis tangential to the face and generally parallel to the ground when the head is ideally positioned, a y-axis generally perpendicular to the x-axis and generally parallel to the ground when the head is ideally positioned, and a z-axis generally perpendicular to the x-axis and to the y-axis and generally perpendicular to the ground when the head is ideally positioned; at least first and second weight ports formed in the body; and at least one weight configured to be retained at least partially within at least one of the first and second weight ports; the first and second weight ports being located on the body such that vertical displacement of a center of gravity of the golf club is achieved by placement of one or more weights in at least one of the first and second weight ports; wherein the vertical displacement of the center of gravity is up to about 2.8 mm.
