PROGRESSIVE IRON SET

摘要

The present invention is directed to a set of golf clubs comprising long irons, mid-irons and short irons. The irons have a progressive horizontal CG location. Preferably, the long and MID irons have a CG located between about 1 mm and 3 mm towards the hosel and the short iron CG is located between about 3 mm and 4 mm toward the hosel. Further the irons can have a substantially constant blade width with progressively increasing toe height and progressively decreasing scoreline width.

主权项

1. A set of golf clubs comprising at least a first golf club, a second golf club, and a third golf club, wherein:
the first, second and third golf clubs each comprising a heel, a toe, an upper surface, a lower surface, a hosel and a front face having a face center, and the first golf club further comprising a first loft angle (LA1) of between 15 and 25 degrees and a first center of gravity positioned horizontally from the face center towards the hosel by a first distance, the second golf club comprising a second loft angle (LA2) of between 26 and 36 degrees and a second center of gravity positioned horizontally from the face center towards the hosel by a second distance, and the third golf club comprising a third loft angle (LA3) of between 37 and 47 degrees and a third center of gravity positioned horizontally from the face center towards the hosel by a third distance, wherein the first distance and the second distance are approximately constant and the third distance is at least 30 percent greater than the first distance, and wherein the third distance is greater than the values defined by the line CG-Xfc=0.02(LA)+2, where CG-Xfc is the distance of the center of gravity from the face center toward the hosel in the horizontal direction and LA is loft angle.
