Abstract
A high forgiveness wood-type golf club head comprises a body and a face. The body defines an interior cavity and comprises a sole that forms a bottom portion of the golf club head, a crown that forms a top portion of the golf club head and a skirt that forms a periphery of the golf club head between the sole and the crown. The face place is positioned at a front portion of the golf club head opposite a rear portion of the golf club head. The body defines an outer periphery having a generally triangular shape in plan.
Claims27
A golf club head comprising:
- a body defining an interior cavity and comprising a sole positioned at a bottom portion of the golf club head, a crown positioned at a top portion, and a skirt positioned around a periphery between the sole and the crown, wherein the body has a forward portion and a rearward portion;
- and
- a face positioned at the forward portion of the body, the face having an ideal impact location, wherein a face plane is defined to extend tangential to the ideal impact location;
- wherein the body extends a distance L transversely away from the face plane and defines cross-sectional areas A along planes parallel to the face plane and spaced rearward from the face plane by a distance q, wherein a body region is defined between a dimension of q/L of about 0.05 to a dimension of q/L of about 1.0, and wherein within the body region is at least about 50% of the cross-sectional areas A are between an upper cross-sectional area limit Au and a lower cross-sectional area limit A1, where
- Au=5512(q/L)2−14026(q/L)+8875+1200(q/L)+500, and (1)
- A1=5512(q/L)2−14026(q/L)+8875−2000[1−(q/L)]2−300;
- (2)
- wherein the golf club head has a height between approximately 60 mm and approximately 85 mm;
- and
- wherein the golf club head has a head origin defined as a position on the face plane at a geometric center of the face, the head origin including an x-axis tangential to the face and generally parallel to the ground when the head is ideally positioned where a positive x-axis extends towards the heel portion, a y-axis extending perpendicular to the x-axis and generally parallel to the ground when the head is ideally positioned where a positive y-axis extends from the face and through the rearward portion of the body, and a z-axis extending perpendicular to the ground, to the x-axis and to the y-axis when the head is ideally positioned where a positive z-axis extends from the origin and generally upward, wherein the golf club head has a center of gravity with an x-axis coordinate between approximately −5 mm and approximately 10 mm, a y-axis coordinate between approximately 20 mm and approximately 50 mm, and a z-axis coordinate between approximately −10 mm and approximately 5 mm.
