Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Application Field) The present invention is a sports practice used for practicing gripping and swinging sports equipment such as tennis ke, g, baseball bat, g, golf club, wooden sword, etc. Regarding equipment.

(Prior art) Conventionally, this type of sports training device has no information on how to apply grip strength to sports equipment, and those who practice shaking movements of sports equipment are guided by a coach or independently take pictures of the sports equipment. I was practicing exercise.

(Problem that the invention seeks to solve) When gripping and shaking sports equipment, even if the grip force is slightly incorrect, beginners can practice applying grip force where it is unnecessary and then apply it where it is needed. 'Remember: For those who are not beginners, check and adjust how to apply grip strength through practice. If a person who practices swinging sports equipment has a coach, it is easy to learn or check how to apply grip strength with the guidance of a coach.

However, without a coach, it is difficult to practice, memorize, or check how to apply grip strength, and there are many cases where there is no coach. Therefore, when shaking sports equipment in practice rather than in practice, it is often the case that the grip force is not applied properly and the force cannot be fully exerted.

(Means for Solving the Problem) The present invention includes a grip force detection means for detecting the grip force applied to the grip portion of sports equipment, a grip force determination means for determining the degree of grip force applied from the output signal of the grip force detection means, A means for notifying the determination result of the grip strength determining means is provided.

(Function) When gripping and swinging sports equipment, the grip force is detected by the grip force detection means, compared with the reference grip force by the grip strength determination means, the degree of grip force applied is determined, and the result is notified by the notification means. .

(Example) FIG. 1 shows an example of the present invention. This embodiment is an example of a tennis practice device for practicing the swinging motion of a tennis racket.Inside the tennis racket 1 near the grip portion 2, there is a printed circuit board 3 constituting an electronic device. Electronic components 4, reference level setting variable resistors 5 to 7. Speaker 8.
A starting means 9. A pressure sensor 10 and a battery 11 are incorporated.

The starting means 9 is a circuit that is turned on for a certain period of time (longer than the duration of one &, D movement of the racket) every time a suppression operation is performed, and is provided in the grip part 2 so that it can be operated from the outside, and the variable resistors 5 to 7 are connected to the grip part. 2, so that it can be operated from the outside.

The pressure sensor 10 is fitted into the grip portion 2 via a rod 12 to constitute grip force detection means, and detects the grip force applied to the grip portion 2.

FIG. 2 shows the circuit configuration of the electronic device. The electronic components 4 on the printed circuit board 3 include an amplifier 13, a level determination circuit 14.
The sound generating circuits 15 to 17 are constituted by the variable resistors 5 to 17.
7 constitutes a judgment level setting circuit. Level judgment circuit 1
4 constitutes grip strength determination means, and determination level setting circuits 5 to 7
is to arbitrarily set different judgment levels. The audio generating circuits 15 to 17 generate audio signals having different frequencies.

A person who practices swinging the racket 1 grips the grip 2 of the racket 1 with one or both hands, presses the starting circuit 9, and then performs the swinging motion of the racket 1. The electronic device operates when the starting circuit 9 is turned on by a suppressing operation and power is supplied to each part from a power source 11 such as a battery, and the grip force applied to the grip part 2 of the racket 1 is detected by the pressure sensor 10 and transmitted to the amplifier 13. The signal is applied to the level determination circuit 1.4 via. Generally, if the force to grip the grip part 2 is applied during one swing of the racket 1, as shown in FIG. 4, for example, the force will hardly be applied in unnecessary places. The level determination circuit 14 compares the output signal of the amplifier ] 3 with each determination level of the determination level setting circuits 5 to 7 and determines whether or not the grip strength matches the predetermined levels A and B. The sound generation circuits 15 to 17 cause the speaker 8 to emit different sounds based on the respective determination outputs. That is, as shown in FIG. 3, when the grip strength reaches a weak level A and the output signal of the amplifier J3 matches the judgment level of the judgment level setting circuit 50, the level judgment circuit 11 judges the coincidence and generates a sound. The circuit 15 is operated and a single tone is emitted from the speaker 8. When the grip strength reaches a medium level B and the output signal of the amplifier 13 matches the judgment level of the judgment level setting circuit 6, at t2, the level judgment circuit 4 judges the coincidence and operates the sound generation circuit 16. , two consecutive single tones are emitted from the speaker 8. When the grip strength reaches a strong level C or higher, the output signal of the amplifier 13 is determined by the judgment level setting circuit 7.
From t3 to t4, the level determining circuit 14 determines this and operates the sound generating circuit 17, so that three consecutive single tones are repeatedly emitted from the speaker 8.

Therefore, the time point t1 when the grip strength reaches each level A, B, and C
% ta is announced at the beginning of a single tone, 2 consecutive single notes, and 3 consecutive single notes, and the grip strength decreases to level C at time t4
You will be notified when the repetition of three consecutive single tones ends, and you will know how to apply grip strength. When swinging the racket 1, aim for how to apply grip strength that is generally considered ideal, or how to apply grip strength when you are at your best. As shown in Figure 4, a single note,
By swinging the racket 1 so that the beginning of two consecutive single notes, the beginning of three consecutive single notes ti % ta, and the end of repetition of three consecutive single notes t4, it is possible to remember or confirm how to apply the target grip force.

Note that the above-mentioned determination level may be other than three.

Further, even if the sports equipment is a baseball bat, a golf club, a wooden sword, etc. other than a tennis racket, the present invention can be applied in the same manner as in the above embodiments.

(Effects of the Invention) As described above, the sports training device according to the present invention detects the grip force applied to the grip part of the sports equipment, compares it with a predetermined grip force, determines the degree of grip force applied, and notifies the user of the result. Since the notification is given by means, it is easy to remember or confirm how to apply grip strength even without a coach, and it is possible to fully exert force when actually swinging sports equipment in a match or the like.
