GOLF CLUB HEAD WITH IMPROVED PERFORMANCE

摘要

A golf club head with an improved sweet spot, defined as a portion of the striking face that has at least 99.7% of the maximum ballspeed is disclosed herein. More specifically, the present invention discloses a golf club head with a significantly circular sweet spot that encompasses at least about 1.5% of the total striking face. A golf club head in accordance with the present invention may generally have a improved face geometry with an elliptical factor of greater than about 0.5, a beveled transition portion around the striking face of the golf club head, a variable face thickness region with decreases thickness, or even a tilted bulge and roll radius all helping improve the performance of the golf club head.

主权项

1. A golf club head comprising:
a striking face with a frontal surface area of greater than about 3,600 mm2; a posterior body portion further comprising a crown portion and a sole portion, and a beveled transition portion at least partially surrounding a perimeter of said striking face, connecting said striking face with said posterior body portion; wherein said crown portion is coupled to an upper portion of said striking face and said sole portion is coupled to a lower portion of said striking face; wherein said striking face has an elliptical geometry having a major axis less than about 120 mm and a minor axis greater than about 40 mm, and wherein said beveled transition portion further comprises a toe beveled transition portion and a heel beveled transition portion, and a radius of curvature of said toe beveled transition portion is different from a radius of curvature of said heel beveled transition portion.
