Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a golf club, and more particularly to a golf club capable of determining whether or not a golf ball is caught on the face surface at the time of impact.

Prior Art In order to make an accurate shot, first of all, it is important to learn the basics of swing and to reliably catch the golf ball on the face surface, and in the case of beginners, it is necessary to practice this kind of practice. . However, it is not easy to judge whether or not the golf ball is caught on the face surface even if the player is a beginner.

To cope with this problem, a golf club has been proposed in which when a golf ball is caught on the face surface, it can be automatically notified by voice or the like. As shown in FIG. 3, in this golf club, when the face surface 2 of the head 1 is configured to be movable back and forth and hits a golf ball, the golf ball is pushed inward, the contact bolt 3 comes into contact with the contact 4, and the power is supplied. It enters and sounds are emitted by the sound generator built into the shaft.

Problems to be Solved by the Invention According to the above-mentioned golf club, even a beginner can judge whether or not the ball is caught on the face surface. In addition to reducing the flight distance and the flight distance, the face surface tilts depending on the hitting area, the directionality of the ball is not fixed, and the impact resistance of the built-in moving parts also becomes a problem.

It is an object of the present invention to solve the above-mentioned problems and to provide a golf club capable of determining whether or not a golf ball is caught on the face surface.

According to the present invention, therefore, at least a part of the face surface integrated with the head is formed of a light-transmissive hard body, and the optical sensor is arranged inside the part formed of the hard body. A golf club is provided in which, when the light is blocked from entering the optical sensor, the display is displayed by the determination means provided on the shaft.

Examples of the optical sensor include a photoconductive effect type optical sensor, a photodiode, and the like, and examples of the determination unit include a sound generation mechanism and a light emitting device such as a light emitting diode.

When the golf ball hits the face surface at the time of operation impact and blocks the light incident on the optical sensor, it is displayed by the discriminating means, thereby confirming that the ball is caught on the face surface.

By arranging multiple photosensors on the face surface and providing a light-emitting device for each, it is possible to determine which part of the face surface the golf ball hits. Will be able to

Example A face surface 12 of a head 11 is formed of a light-transmissive hard resin, a block 14 in which a photoconductive effect type optical sensor 13 is fitted and inserted in the center is fixed inside, and is fitted into the head and screwed. There is.

The optical sensor 13 is connected to a sound generating device 16 built in the handle portion 15 so as to form a circuit with a power source composed of a battery 17, and a switch 18 incorporated in the circuit has an end portion of the handle portion 15. It is exposed and provided.

In use, the ball is hit after the switch 18 is turned on. When the ball hits the center of the face surface and the light entering the optical sensor 13 is blocked by this, a sound is emitted by the sound generating device 16 and it is confirmed that the ball hits the face surface.

In the above embodiment, when the light entering the optical sensor is blocked, a sound is emitted, but in another embodiment,
A light emitting diode which is provided with one or more optical sensors on the face surface and is connected to the optical sensor at the shaft part of the shaft, preferably the end face of the shaft part, and emits light for a certain period of time when the light entering the optical sensor is blocked Is arranged corresponding to each sensor,
Display which part of the face is hit.

In the above-described embodiment, the entire face surface is formed of the light-transmitting hard resin, but in another embodiment, only the portion where the photosensor is provided is formed of the light-transmitting hard body.

Effect of the Invention The present invention is configured as described above, and has the following effects.

According to the golf club of claim 1, whether or not the golf ball is caught by the face surface at the time of impact without causing any problems similar to the previous ones, such as the flight distance of the ball, the directionality, and the durability of the golf club. Can be determined.

By disposing a plurality of optical sensors on the face surface and providing a light emitting device corresponding to each sensor as in the second aspect, it becomes possible to know at which part of the face surface the ball is caught.
