First Claim
Patent Images
1. A wood-type golf club head comprising:
- a body comprising a face plate 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 the crown, wherein the body defines an interior cavity;
at least a first weight having a first weight mass between about 1 gram and about 18 grams and configured to be retained at at least a first position located on the body; and
at least a second weight having a second weight mass between about 1 gram and about 18 grams and configured to be retained at at least a second position located on the body;
wherein the head has a golf club head origin positioned on the face plate at an approximate geometric center of the face plate, the head origin including an x-axis tangential to the face plate 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, wherein a positive x-axis extends toward a club head heel, a positive y-axis extends toward the cavity, and a positive z-axis extends away from the ground with the head ideally positioned, andwherein the first position has a head origin z-axis coordinate between about 5 mm and about 15 mm and a head origin x-axis coordinate between about 0 mm and about −
60 mm, and the second position has a head origin z-axis coordinate between about −
30 mm and about −
10 mm and a head origin x-axis coordinate between about 0 mm and about 60 mm, and a volume of the golf club head is between about 180 cm3 and about 600 cm3; and
wherein a difference between the first weight mass and the second weight mass multiplied by a distance between the first position and the second position is between about 950 g-mm and about 14,250 g-mm.

Abstract
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.
