    • Embodiments of a putter-type golf club head with an increased moment of inertia about the X axis (MOIXX) and an increased moment of inertia about the Z axis (MOIZZ) are disclosed. Generally, the MOIZZ is increased by designing the putter such that the center of gravity (CG) of the putter head is located at or behind the geometric center of the putter head. Additionally, the mass of the putter head is concentrated at the outer edges of the putter head. To accomplish this, the ratio of the width of the front of the putter head to the width of the rear of the putter head is no greater than 0.55:1. The MOIXX is further increased by locating the CG relatively close to the bottom of the putter head.
    • 公开了具有围绕X轴(MOIXX)增加的转动惯量的推杆式高尔夫球杆头的实施例和围绕Z轴(MOIZZ)的增加的转动惯量。 通常,通过设计推杆使推杆头的重心(CG)位于推杆头的几何中心或之后,增加了MOIZZ。 此外,推杆头的质量集中在推杆头的外边缘。 为了达到这个目的,推杆头前部宽度与推杆头后部宽度之比不大于0.55:1。 通过将CG相对靠近推杆头的底部定位,进一步增加了MOIXX。
