Connected.

Hereinafter, an operation process of the embodiment will be described.

The golf swing exerciser 100 shown in FIG. 1 may be understood together by explaining the golf swing exerciser shown in FIG.

3 is a configuration diagram illustrating an operation process of the second embodiment of the present invention.

When the golfer's hand and the golf practice swinger 200 are backswinged to be in line with the straight line in the state that the swinger 200 is aligned with the straight line XQ, the moving body (from the time when the first stopper 30 is higher than the second stopper 40) 20 moves to the second stopper 40 side (a direction) so that the movable body 20 is brought into contact with the electrical terminal 43 of the second stopper 40.

In the golfer's swing, if the swing reaches the YP linear state that is sharply backswinged compared to the slope of the shaft 10 in the address state, or when the ZR linear state that is gently backswinged is not reached, the correct swing state is not reached. Practice checking your swing by looking in the mirror to see if you are swinging. However, if you swing while looking at the mirror like this, it is difficult to check the correct swing because the swing is deformed the moment the head is turned because the swing must be done.

However, when the movable body 20 comes into contact with the electrical terminal 43 of the second stopper 40, the electricity is supplied to the laser device 51 by the built-in battery of the electric circuit 44. Since the laser is emitted from the laser, the reflection point of the laser is formed on the ground, so it is possible to check the inclination of the shaft. If the swing is correct, the reflection point of the laser at the back swing has a straight line parallel to the head. Will move.

Therefore, if you swing while looking at the reflection point of the laser, you can solve the inconvenience of checking your backswing by turning your head. Various light sources may be used instead of the laser device 51, but a device for generating a laser having excellent linearity of light in order to clearly form a reflection point is preferable.

At this time, the laser device 51 may artificially maintain the lighting state at the time of practice by a switch (not shown) so that the swing trajectory from the address state to the end of the full swing can be confirmed.

In addition, when the back swing ends and the down swing is performed, the movable body 20 moves in the b direction by the centrifugal force to come into contact with the shock absorbing member 38 inside the first stopper 30, and the first stopper 30 and the shock absorbing member. Compresses the spring 32 so that the projecting surface 41 of the shock absorbing member 38 conducts the electrical terminal 36, and the LED 45 in the electrical circuit 44 by the conduction of the electrical terminal 36. Turn on the power supply. At this time, the light source is not limited to the LED, but a small power consumption LED is preferable.

The spring 32 buffers the moving body 20 directly impacting the first stopper 30, thereby delaying the point at which the LED 45 lights up from the point of contact of the moving body 20 with the first stopper 30. It also plays a role of delaying the lighting time so that it lights up at the lowest point (impact time) on the XQ line.

When the down swing ends after the impact point, and the centrifugal force becomes smaller than the restoring force of the spring 32, the electric terminal 36 and the shock absorbing member 38 are separated, and the electric terminal 36 is in an uncontrolled state. 45) is turned off.

So-called head-up prevention is emphasized in golf lessons because it is very important to ensure that the ball is hit exactly at the point of impact in golf to improve the direction and power of the ball.

In the swing exerciser 100, the LED is turned on for a predetermined time around the impact point, and the lighting of the LED at the time of swing practice remains a strong stimulus to the golfer, thereby preventing head-up during the practice.

In addition, since the lighting state is maintained in a section having a large centrifugal force during the downswing, it is possible to check which section has a high speed during the swing. This prevents the caulking from being released too early before impacting, leading to a fast swing speed at the beginning of the downswing and slowing the swing speed at actual impact.

1 and 2, the stopper body and the second stopper body 42 of the first stopper 30 are made of synthetic resin, and the shock absorbing member 38 is formed of a metal material. It is a matter of course that when the insulating material is used in parallel, it can be formed of a metal material.

According to the present invention having the above object and configuration, it is possible to protect the first stopper against the impact of the moving body can use the swing exerciser for a long time, to maintain the correct backswing trajectory by checking the reflection point of the laser, impact Head-up can be prevented by stimulation of LED light at the point of time, and it is possible to identify the section with the highest speed by the lighting state of LED.
