JPH0679027A - Golf club, baseball bat and tennis racket for light emitting type training - Google Patents

Abstract

PURPOSE:To immediately check the swing state of a club of a golf trainee, for example, the angle of a face surface, a lie angle or a hand fast degree on the spot at the time of swing. CONSTITUTION:Flashing planar light emitting elements 3a, 3b, 3c are provided to the surfaces of the shaft 1 and head 2 of a golf club. Flashing light emitting elements are provided to the surface of a baseball bat or tennis racket in the same way. When the golf club, the baseball bat or the tennis racket is swung, flashing images are looked like stroboscopic photography by the afterimage effect of an eye. By this constitution, a swing state can immediately be checked on the spot and trial and error is easily performed by variously changing the factors of the swing state and effective training can be performed.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an exercise equipment for practice for judging whether the swing is good or bad in sports where it is required to swing the equipment accurately.
Specifically, this includes golf clubs, baseball bats, tennis rackets, and badminton rackets, table tennis rackets, gateball clubs, etc., which are used in the same manner as these.

[0002]

2. Description of the Related Art Japanese Patent Application No. 60-5098
No. 3 is known. This is provided with a flashing light source linearly extending in a direction parallel to the face surface on the upper surface of the golf club, and a light source which is always lit on the upper surface of the golf club at a position corresponding to the center of the face surface. . By shaking this, the practitioner can see the trajectory of the golf club and the inclination of the face surface due to the afterimage effect.

[0003]

However, the information that the practitioner wants is not limited to the above. For example, in the case of the inclination of the club, only the inclination of the club about the vertical axis is known in the above example, but the practitioner also wants to know other inclinations about the front-rear axis and the left-right axis. It is also very useful to know the delicate position and posture of the club head at the moment of hitting the ball. Further desired information is the shaft position. From this information, it is possible to know the state of the shaft's “damage” during the swing, the position of the hand at the moment of hitting the ball, and the like. However, it is difficult to know the above at present. The present invention aims to meet the needs of these practitioners.

[0004]

[Means for Solving the Problems] A planar light-emitting body is provided on the entire surface or a part of the surface of a head portion or shaft portion of a golf club, and this is made to blink at high speed. Further, in the case of other exercise equipment as well, similar to the golf club, a blinking planar light-emitting body is provided on the whole surface or a part thereof.

[0005]

By the blinking of the surface of the golf club at high speed, the practitioner can see the shape of the club head and the shaft at each position on the swing trajectory by the afterimage effect of the eyes. The same applies to other exercise equipment.

【Example】

1 is a perspective view of a light emitting type practice golf club, FIG.
The club head 2 is fixed to the tip of the shaft 1 to form a normal golf club, and the light emitter 3 is mounted on the surface of the club head and the shaft. However, the light emitter may not be attached to a place such as the bottom of the club head that is not visible to the practitioner, a place such as a shaft grip where the user holds it, or a place where it is unnecessary.

The structure of the light emitter is roughly divided into two cases. One of them is the case where the light source directly emits light. The other is a case where a light source is provided separately and the light emitter emits light indirectly upon receiving the light. As an example of the former,

As shown in FIG. 1, for example, as in a plasma display, a planar light-emitting body 3 that shines by itself is directly attached to the surface of a club. An example of the latter is

As a light source that blinks at high speed as shown in FIG. 7, for example, a plurality of light emitting diodes 19 which are sufficient to secure the brightness of the surface are arranged inside the club, and the club surface shines upon receiving this light, for example, a semitransparent resin. It consists of 20. A transparent material such as methacrylic resin 21 is provided between the light source and the surface. If you shake this club, it will appear to the practitioners as if the surface of the club is blinking. Instead of directly blinking the light source, it is also possible to turn on the light source continuously and place a liquid crystal shutter between the light source and the light emitter to open and close it at high speed to blink the light emitter.

The light source of the luminous body is

FIG. 2 blinks according to a predetermined pattern as shown in FIG. The lighting time is preferably about 1 / 10,000 second when the head speed is as high as 40 m / sec like a driver so that the image does not blur, and it is a little longer in the case of a slow iron or a slower putter. It is preferable to do so that the brightness can be secured. The light-off time may be selected depending on how often the image is viewed, but in the case of a driver, when trying to view the image at 8 cm intervals, it is about 500.
It is about one second. If this is made variable, the practitioner can select it arbitrarily. As an example of this electric circuit

[Figure 3] There is. Switches, power supplies, circuit elements, etc.

If the shaft is built into the shaft as shown in FIG. 1, the appearance is smart and the handling is easy. However, if you need a powerful power supply, such as when you really want brightness, you can rely on an external power supply through a cord. It is also possible to use different colors depending on the location of the light emitter. For example, if different colors are used for the front surface 3a, the upper surface 3b, and the shaft portion 3c of the head, the practitioner can easily understand the shape of the club.

The golf club embodiment may be applied to other exercise equipment.

FIG. 4 is an example of a baseball bat. The self-luminous illuminant 14 covers the entire surface of the bat. Instead of this light emitter, it is possible to arrange a plurality of light emitting diodes inside as described in the embodiment of the golf club. In the case of a tennis racket or a badminton racket,

As shown in the example of the tennis racket of FIG. 5, a light emitting body 17 is provided on the surface of the frame body 15 other than the strings.

[0010]

When the golf club is shaken, the club shines intermittently in a preset pattern, so that the practitioner

[Fig. 6] After the club passes through as shown in Fig. 6, the club at each flashing moment can be viewed as one face at the same time, as if the stroboscopic photograph was seen. This allows the practitioner to see the result of his or her swing as it is, and at the moment it swings. These two characteristics are important factors for practicing. This will be described below step by step.

To explain the importance of seeing the results as they are, the present invention allows the practitioner to check any part of the club from any direction because the shape of the club is represented three-dimensionally. For example, you can understand the opening angle of the face, the lie angle, the situation of the shaft's “gain”, and even the bending of the shaft. In addition, even if you want to check from the direction where the practitioner cannot directly see, such as checking the lowest point of the swing, you can do it by using a mirror and having another person see it.

Next, the importance of immediate understanding will be described. In other words, the practitioner can see the result while the image of the swing is still on the body, so it is easy to perform trial and error as to which of the factors related to the quality of the swing should be changed to affect the result. As a result, the practitioner can easily learn how to swing the club to make a correct swing, and can practice efficiently. This is quite different from recording a swing with a video or the like and then viewing the result through the screen after a while, which is very effective.

The above two characteristics are excellent as a tool for a common dialogue between a teacher and a trainee, especially in a golf classroom. As is often the case, trainees often do not understand his flaws, which the teacher points out. For example, the position of the hand at the moment of hitting the ball greatly affects the ball streak of the ball. That is, if the hand is fast, the ball jumps low, but if the hand is delayed, the ball jumps high.
It is quite difficult for an untrained trainee to recognize the position of the hand at the moment when the ball hits. In such a case, by using the club of the present invention, the movement of the shaft can be seen well, and if it is used as a common recognizing means for both, the trainee can understand well what the teacher points out and the dialogue can be carried out smoothly. Also, since the result can be seen instantly, the time spent for one trainee can be shortened, and an efficient lesson can be given to the teacher who teaches many trainees.

In the case of a practice baseball bat, the surface of the bat during the swing can be seen, so that the angle and hitting point of the bat at the moment of catching the ball can be accurately grasped. Also, whether or not the swing is sharp can be seen by looking at the trajectory of the image of the entire swing. Furthermore, it becomes possible to judge the speed and acceleration of the bat by looking at the distance between the images, and by utilizing these, it becomes possible to practice scientifically.

The practice tennis racket is similar to the golf club and the baseball bat, and the movement of the racket can be seen directly with the eyes. Especially in the case of a racket, if the ball actually hit does not hit the sweet spot, the racket can be seen twisting and spinning. You can practice effectively by these.
