交叉点。 FIG. 1a is a plan view from above of a golf club according to an embodiment of the present invention in a state that can be held by a practitioner;
Figure b is a front view of the head part, Figure c is a bottom view of the head part with the bottom plate removed, and Figures 2 to 4 show a driver using the driver according to the present invention. This is a diagram to explain the relationship between the trajectory of two light emitting elements when viewed from the ground, the swing form, and the shape of impact. Figure 2 is a diagram showing the trajectory of two light emitting elements in the case of a square impact, and Figure 3 is a diagram showing the trajectory of two light emitting elements in the case of a square impact. Figure 4 shows the trajectory of the two light emitting elements in the case of open impact, Figure 5 shows the trajectory of the two light emitting elements as seen from the practitioner during putting. FIG. 3 is a diagram for explaining the relationship between the swing form and the shape of impact. <Explanation of symbols> 1...Driver, 2...Head, 3...Face, 4...Sweet spot, 5...Shaft, 6...Grip, 7, 9...

Claims

[Claims for Utility Model Registration] (1) The light emitting end is exposed on the upper surface of the head and is located on a straight line that passes through the sweet spot of the head and is parallel to a perpendicular line drawn to a plane that is in contact with the sweet spot. A golf club comprising two light emitting elements arranged at a predetermined interval, and a mechanism for removably storing a battery for supplying power to these light emitting elements in the head, shaft, or grip of the club. (2) The golf club according to claim 1, wherein two light emitting elements are arranged in the line of sight of a practitioner who can grip the golf club looking at a perpendicular line set up at the sweet spot of the club. (3) The golf club according to claim (1), wherein at least the light emitting element on the face side is disposed so as to be sunk below the upper surface of the head.
