摘要： A golf club, particularly a “putter” or “chipper”, is provided with a concave ball striking face that establishes line contact with a golf ball rather than the usual point contact and enhances the capability of a user to control the direction of ball movement resulting from a golf stroke. The concave ball striking surface may be curved and may have the same or greater curvature than the curvature of a golf ball and may have smoothly and gently merging surface regions of compound curvature. The concave ball striking face surface may have compound regions including a curved region and a planar region being smoothly and gently merged. The concave ball striking surface may be defined on an integral metal club head structure or may be defined by a polymer insert that is recessed into an insert receiving receptacle of the club head. Additionally, the face portion of a golf club head may have a recessed face to further aid in training and to enhance the efficiency and accuracy of ball movement resulting from a golf stroke.
摘要翻译：一个高尔夫球杆，特别是一个“推杆”或“切碎机”，设置有一个凹球打击面，它与高尔夫球而不是通常的点接触线形成线接触，增强了使用者控制球运动方向的能力由高尔夫中风造成。凹球打击表面可以是弯曲的并且可以具有与高尔夫球的曲率相同或更大的曲率，并且可以具有平滑且温和地合并的复合曲率的表面区域。凹球冲击面表面可以具有包括弯曲区域和平坦区域的复合区域，其平滑且温和地合并。凹球打击表面可以限定在整体的金属球杆头结构上，或者可以由凹入到球杆头的插入物接收容座中的聚合物插入物限定。此外，高尔夫球杆头的面部可以具有凹面以进一步帮助训练，并且提高由高尔夫球冲击造成的球运动的效率和精度。
