摘要： The inventive golf club comprises a head of a metal having a face and a flexural range, defined in the face, where the quantity of flexure in a direction perpendicular to the face is at least 45% of the maximum quantity of vertical flexure of the face. The flexural range is arranged in coincidence with a hitting spot distribution range of a player in the face. Alternatively, a flexural range having a spring constant of at least 2 kN/mm and not more than 4 kN/mm is present in the face of the inventive golf club.

摘要： A wood golf club head is adapted to achieve the maximum flight distance or optimum trajectory of a golf ball, by incorporating features to achieve an appropriate correlation between launch angle and backspin speed of a golf ball that is struck by the club head. A wood golf club head is designed to achieve a launch angle and a backspin speed of a golf ball located in an angle-spinspeed region defined by an ellipse having a center point O(21, 1800), length of a major axis L equal to 2100(rpm), length of a minor axis S equal to 5.7(deg), and tilt angle θ of the major axis measured in a counterclockwise direction from the vertical axis equal to 0.25(deg), wherein the horizontal coordinate designates the launch angle(deg) of the golf ball, the vertical coordinate designates the backspin speed(rpm) of the golf ball, and the horizontal and vertical axes have the same numerical scale. Preferably, the wood golf club head has a face formed of a low friction material and a loft angle of 13 to 20 degrees.
摘要翻译： 木质高尔夫球杆头适于通过结合特征来实现高尔夫球的最大飞行距离或最佳轨迹，以实现由球杆头撞击的高尔夫球的发射角度和后旋速度之间的适当相关性。 木质高尔夫球杆头被设计成实现位于由具有中心点O（21,1800）的椭圆限定的角度旋转区域中的高尔夫球的发射角和后旋速度，长轴L的长度等于 2100（rpm），短轴S的长度S等于5.7（度），以及从垂直轴的逆时针方向测得的长轴的倾斜角θ等于0.25（度），其中水平坐标表示发射角 （deg），垂直坐标表示高尔夫球的后旋转速（rpm），水平轴和垂直轴具有相同的数字刻度。 优选地，木质高尔夫球杆头具有由低摩擦材料形成的面和13至20度的顶角。

摘要： A golf club having a value of L not less than 45.5 inches, with L representing a club length measured with a 60-degree method, includes a shaft, a grip attached to one end of the shaft, and a head attached to the other end of the shaft. A value of r/L is equal to or not smaller than 0.658 and equal to or not greater than 0.732, where r represents a distance from an upper end of the grip to the center of gravity of the golf club. Thus, a long-length golf club achieving an increased head speed can be obtained.
