摘要： PROBLEM TO BE SOLVED: To provide a golf club head that is capable of achieving an improved sweet spot, defined as a portion of a striking face that has at least 99.7% of the maximum ball speed.
SOLUTION: The golf club head 100 has the significantly circular shaped sweet spot which surrounds at least about 1.5% of a total striking face 102. The golf club head 100 includes: an improved face geometry whose elliptical factor is, generally, greater than about 0.5; a beveled transition portion 112 around the striking face 102 of the golf club head 100; a variable thickness area which decreases thickness; or a tilt bulge and roll radius. These are all useful to improve performance of the golf club head 100.

摘要： PROBLEM TO BE SOLVED: To provide a golf club head capable of utilizing the geometry of a striking face of the golf club head itself to increase the size of a sweet spot of the golf club head.SOLUTION: A striking face 102 may have a frontal surface area which is greater than about 3500 mm2. A posterior body portion 104 may further comprise: a crown portion 106 coupled to an upper portion of the striking face 102; and a sole portion coupled to a lower portion of the striking face 102. A beveled transition portion is at least partially surrounding the perimeter of the striking face 102, connecting the striking face 102 with the posterior body. The striking face 102 may have a sweet spot, defined as the area of the frontal surface having at least 99.7% of the maximum ball speed achievable by a golf club head 100, which encompasses a portion greater than about 1.5% of the frontal surface area of the striking face 102.
摘要翻译：要解决的问题：提供一种能够利用高尔夫球杆头本身的击打面的几何形状的高尔夫球杆头，以增加高尔夫球杆头的甜点的尺寸。解决方案：打击面102可以具有前部大于约3500mm 2的表面积。后体部分104还可以包括：冠部106，其联接到打击面102的上部; 以及联接到打击面102的下部的底部。斜面过渡部分至少部分地围绕打击面102的周边，将击打面102与后身连接。击打面102可以具有甜点，其定义为前表面的面积具有由高尔夫球杆头100可实现的最大球速的至少99.7％，其包括大于前表面积的约1.5％的部分的击打面102。
