    • The golf club head (14) of the present invention has a face portion (24) for striking a golf ball, a crown portion (18) connected to the face portion (24), and a sole portion (22) connected to the face portion (24). The ratio of either lower of a first equivalent rigidity of a crown member (18) and a second equivalent rigidity of a sole member (22) to the higher is equal to or less than 0.75. The present invention provides a golf club (10) provided with the hollow golf club head (14) capable of increasing the carry of a golf ball based on a technique for increasing the carry of a golf ball other than conventional ones such as adjustment of the loft angle and reduction in the thickness of the striking surface, and provides a method of designing such a hollow golf club head as well.
    • 本发明的高尔夫球杆头(14)具有用于击打高尔夫球的面部(24),连接到面部(24)的冠部(18)和连接到面部 部分(24)。 冠部构件(18)的第一等效刚度的较低值与鞋底构件(22)的第二等效刚度之比等于或小于0.75。 本发明提供一种高尔夫球杆(10),该高尔夫球杆(10)具有中空高尔夫球杆头(14),该高尔夫球杆头(14)能够根据用于增加高尔夫球的进位的技术,而不是常规的高尔夫球杆 倾斜角度和击打表面的厚度的减小,并且提供了一种设计这样的中空高尔夫球杆头的方法。

    • An optimal golf club shaft for a golfer is selected from among various golf club shafts, the following. At first, a head speed of a golf club at a point when the golf club strikes a golf ball during a golf swing and a downswing time amount from a top point in time when a downswing begins during the golf swing until a golf ball striking point in time are detected. Then a golf club shaft stiffness suited to the golf swing by using the head speed at the time the golf ball is struck and the downswing time amount is computed. Finally, a golf club shaft having the computed golf club shaft stiffness is selected. The golf club shaft stiffness is computed such that the optimal golf club shaft becomes stiffer as the head speed becomes higher and/or as the downswing time amount becomes longer.
    • 以下从各种高尔夫球杆轴中选择一个用于高尔夫球手的最佳高尔夫球杆杆。 首先,在高尔夫挥杆期间高尔夫球杆打高尔夫球时的高尔夫球杆的头部速度以及在高尔夫挥杆期间向下摆动开始到高尔夫球击球点的顶点时间的下降时间量 及时检测。 然后通过使用在打高尔夫球时的头部速度和计算下摆时间量来适用于高尔夫挥杆的高尔夫球杆轴刚度。 最后,选择具有计算出的高尔夫球杆杆刚度的高尔夫球杆杆。 计算高尔夫球杆轴刚度,使得当头部速度变高和/或下降时间变长时,最佳高尔夫球杆杆杆变得更硬。
