IRON TYPE GOLF CLUB HEAD AND SET

摘要

An iron-type golf club head having a sole channel extending from an exterior of a sole portion toward a face. The sole channel has an axis that intersects the face at an axis-to-face intersection point for at least one position along a channel length, and preferably at least 25% of the channel length. The elevation of the intersection point may below the Ycg distance and the axis defines an angle from the vertical that may be related to the loft. The iron-type golf club head may be incorporated in a set containing club heads with varying degrees of unsupported face area.

主权项

1. An iron-type golf club head, comprising:
A) a heel portion, a toe portion, a top line portion, a sole portion, a leading edge, a trailing edge, a face oriented at a loft, and a hosel having a bore and a bore center that defines a shaft axis intersecting a horizontal ground plane to define an origin point; B) wherein the iron-type golf club head includes a sole channel extending from the exterior of the sole portion toward the face, wherein the sole channel has a channel leading edge, a channel trailing edge, a channel width, a channel length, a channel depth, a channel leading edge setback, and a channel axis establishing a channel angle from the vertical; C) wherein the channel axis intersects the face at an axis-to-face intersection point for at least one position along the channel length; and D) wherein the iron-type golf club head has a center of gravity located:
(i) vertically toward the top line portion from the origin point a distance Ycg;(ii) horizontally from the origin point toward the toe portion a distance Xcg;(iii) a distance Zcg from the origin toward the trailing edge in a direction generally orthogonal to the vertical direction used to measure the Ycg distance and generally orthogonal to the horizontal direction used to measure the Xcg distance.
