Kind Code:
B2
Abstract:
PURPOSE:To obtain a club set corresponding to the athletic ability of a player by sectioning an interval between a maximum hitting distance and a minimum hitting distance, which are obtained respectively according to the minimum value and maximum value of a loft angle corresponding to each head speed, by the difference of the hitting distance, coupling the clubs having the loft angle corresponding to these hitting distances and forming the golf club set for each head speed. CONSTITUTION:When the loft angle of the club is set in a lateral axis in a graph and the head speed of the player is set in a longitudinal axis, an equal hitting distance line can be obtained. For example, when the loft angle is 57 deg., the hitting distance is 80m even in the case that the head speed is any one of 36-44m/s. Then, the 90m hitting distance can be obtained at the 52 deg. loft angle in the case of head speed 36m/s. In the case of the 44m/s, the 90m hitting distance can be obtained at 55 deg.. Such an equal hitting distance line is produced concerning 80, 90,..., 190m so that 10m hitting distance can be obtained between the minimum value 21 deg. to maximum value 57 deg. of the loft angle. Next, the head speed is determined and a lateral line is extended from the head speed. Then, the club of the loft angle in the crossing with the equal hitting distance line is arranged.
