Description
本出願は、2018年1月19日に出願された米国仮特許No.62/619,631、2018年3月16日に出願された62/644,319、2018年7月25日に出願された62/702,996、2018年7月25日に出願された62/703,305、2018年8月14日に出願された62/718,857、2018年11月20日に出願された62/770,000、2018年12月18日に出願された62/781,509、2018年12月18日に出願された62/781,513、による優先権の利益を主張するものである。上記で参照された出願の各々の開示は、その全体が参照により組み込まれる。
および、フレーム32内でファイバが大きく後方に回る(すなわち、前後軸244に平行である)状態で、ほぼフェース中心から外側に向かう方向、である。
図48〜49に概略的に示すように、クラブヘッド10の打撃フェース30は、幾何学的中心800と、打撃フェース30の幾何学的中心800に接するロフト面802とを画定する。いくつかの実施態様において、幾何学的中心800は、打撃フェース周囲804の幾何学的中心点に、および、フェース高さ806の中間点に位置することができる。同様のまたは他の実施例では、幾何学的中心800は、打撃フェース上の溝810の領域によって規定され得る、工学的インパクトゾーン808に関して中心合わせされることもできる。別のアプローチとして、打撃フェースの幾何学的中心は、米国ゴルフ協会(USGA)などのゴルフ管理団体の定義に従って配置することができる。例えば、打撃フェースの幾何学的中心は、USGAのゴルフクラブヘッドの可撓性を測定するための手順の6.1節に従って決定することができる。(USGA-TPX3004, Rev. 1.0.0, May 1, 2008)(http://www.usga.org/equipment/testing/protocols/ Procedure-For-Measuring-The-Flexibility-Of-A-Golf-Club-Head/ で入手可能)(the “Flexibility Procedure”)。
