Summary of invention

Problem to be solved

  At present, the net posts used for badminton practice and games are only one height, and it is the current situation that children must use a 155cm high net regardless of whether they are young children or adults. is there.

  However, for children who are shorter than the net, the net is like a wall, which is a major obstacle to early badminton education and early development and dissemination to athletes.

I will explain in detail about the above-mentioned problems. It is the result of examining the club activities of badminton in elementary and junior high school, but there are two elementary schools in my town, but there is no club activity in badminton. There were few applicants and the situation was not established as a club activity. There are no badminton club activities in junior high school, and it is too late to start badminton from high school.
Currently, there are no badminton club activities at elementary schools. There are few children who have hobbies, and there are few children who are attracted to different interests when they are young, and go on the path of badminton. The start age of badminton is too late compared to other sports.
<For example> Ai Fukuhara from the table tennis world started playing table tennis at the age of 3, Miu Hirano at the age of 3, and Misato Ito at the age of 2. The top players in the sporting world all over the world start fast, it's normal since they are 2-3 years old. The badminton world is too slow. It is very important to acquire the correct technology when you are young. Early talent education is a common sense in the modern sports world. The badminton world should also be emphasized.

  At present, even if children enter the social junior badminton classroom (the practice is only once a week), the badminton net is too high. For example, in the case of 1st and 2nd grade students, the average height for men and women of 6 years old is 116.15cm. 7 years old is 122.10cm, but a high net supported by a 155cm net post cannot smash or push, it is difficult to short service and hairpin, and it is difficult to drive in parallel with the floor. The height of the net becomes a wall, making it difficult to see the movement of the other party, making it difficult to determine the direction of the shuttle flight. You can practice only high clear and drop, you can only drive mountain-shaped flights to hit the drive. I can't play the same stroke and flight game as adults, so I feel inferior and quit without confidence. Although the internet is expensive for children, it is a major obstacle to the early education and popularization of badminton.

In addition, for badminton, the shuttle flight is determined by the hit point for children, the bounce point determines the shuttle's falling point, especially in the case of the most aggressive smash hit, the high hit point and short A drop point is required, but it is the most attractive technique for children who are shorter than the net, but it must be abandoned. Also, in the case of services, it cannot be an aggressive fly-driven service. It is extremely difficult to acquire full-scale technology.
Badminton hits the body as if it were remembered. In previous posts, the height of the badminton changes, so the hitting point, flight, and falling point of the shuttle change, and the nerve causes an illusion and makes a mistake. Short stature children are practicing mainly on mountain-shaped flights (but mountain-shaped flights are a fatal failure flight during a badmint battle). It's hard to correct the familiar habits, and it takes too much time for the athletes to develop early, because the entire technology has been seized. This is the current situation surrounding children. It is necessary to reform the height of the net post for children.

The difference between the average height of elementary and junior high school students and the net post. Provided as reference material.
Elementary school first grade 6-year-old girl: average height 115.7cm Boy: average height 116.6cm The average gender is 116.15cm.
Net post height: 155cm, height of children is 38.85cm lower than net.
Elementary school second grader 7-year-old girl: average height 112.7cm Boys: average height 122.5cm The average gender is 122.1cm.
Net post height: 155cm, height of children is 32.9cm lower than net.
Elementary school third grader 8-year-old girl: average height 127.4cm Boy: average height 128.3cm The average gender is 127.85cm.
Net post height: 155cm, height of children is 27.15cm lower than net.
Elementary school 4th grade 9-year-old girl: average height 133.5cm Boy: average height 133.6cm The average gender is 133.55cm.
Net post height: 155cm, height of children is 21.45cm lower than net.
Elementary school 5th grade 10-year-old girl: Average height 140.2cm Boy: Average height 138.9cm The average gender is 139.55cm.
Net post height: 155cm, children's height is 15.45cm lower than the net.
Elementary 6th grade 11 year old girl: Average height 147.0cm Boy: Average height 145.1cm Male and female average is 146.05cm.
Net post height: 155cm, height of children is 8.95cm lower than net.
Junior high school student 12 years old Female: 151.8cm, Male: 152.3cm, Average 152.05cm, 2.95cm lower than the net post.
Junior high school student, second grade, 13-year-old female: 154.8cm, male: 159.5cm, average 157.15cm, 2.15cm higher than the net post.
Junior high school student, 14 year old female: 156.5cm, male: 165.0cm, average 160.75cm, 5.75cm higher than the net post.

Adult 20-year-old to 24-year-old girl: average height 158.6cm, boy: 171.65cm, male and female average height 165.125cm.
Net post height: 155cm, adults are 10.125cm taller than the net. The height of the net is appropriate for adult height.

Regarding the difference between the height and net post above, I saw a verification experience from the standpoint of first graders. Taking the difference between the height of first graders and the net as an example, the average height of an adult is 165.12cm When we played 38.85cm and the post was 203.97cm high, we were able to succeed only in two types of basic badminton flights, high clear and driven clear. I found the problem that the net was too expensive. It is impossible for young children to train their entire skills.

The present invention has been made on the basis of the above circumstances. “In addition, referring to other competitions, for example, basketball is an elementary school student, the ring height is 2.60 m, the adult ring is 3.05 m high, Uses 7 kinds of balls for adults and high school students, 6 for junior high school students, mini basketball for lower grades, and 3 types of balls.
Soccer goal size is 7.32m x 2.44m for junior high school students and above, 5.00m x 2.15m for elementary school students, 3 balls for elementary school junior high school students and 4 balls for junior high school students, 5 from high school No. ball is used.
About height of volleyball net, it is 2.00m (men and women) for elementary school students, 2.30m (for men), 2.15m (for women) for junior high school students, 2.40m (for men), 2.20m (for women) ), 2.43m (for men), 2.24m (for women) for general people, and rules for each of small, medium, high, general, and gender. "
The aim is to solve the problem that the net is too high for young children and to reform the current badminton net post so that the children can acquire full badminton skills when they are in elementary school. It is intended to provide a badminton net multi-purpose post that adds six parts and plays multiple roles in one set.

Means to solve the problem

In order to solve the above problems, in the problem that children cannot hit the correct stroke and flight at the height of the current badminton net according to the aspect of the present invention,
When calculating the ratio of the average height of men and women aged 20-24 years old and the height of the current badminton net post, the average badminton net post height of the elementary school part is calculated based on the difference between the net lower than the person. The height of the outer tube post post is set to the average height standard for first graders, which is lower than the height, and the post height is set to 6 levels according to the 6 elementary classes.
A badminton net multi-purpose post is provided.

In the above-mentioned invention, the determined outer pipe strut is attached to the following adjusting device, and the following structural steps are required for the adjustment / lowering adjustment technical configuration of the adjusting device. The inner pipe strut / inner pipe strut supporting the net An adjustment lever that raises and lowers the upper / lower left / right adjustment lever (fixed position hole, vertical main route, horizontal support route)
The operation lever is attached to the lower part of the inner pipe strut to form the inner pipe strut body, and the adjustment lever moves the inner pipe strut body up and down,
The fixed-position holes are fixed at their respective heights from first graders to adults. The vertical route that was opened on the outer wall of the outer pipe strut is the passage where the adjustment lever is raised and lowered, and the horizontal support route is that the adjustment lever is from this route. Passage to a fixed-position hole,
The inner pipe strut body is moved up and down by the adjusting lever through the main route of the outer pipe strut, and then through the horizontal support route to the fixed position hole of each height (the height of the fixed position hole is The adjustment height of the plus inner pipe strut body is the height of the badminton net post).

  In addition, the above-mentioned badminton net post has been reformed by the adjustment device for rising and falling, and 6 steps are added, so that rising and falling can be adjusted in 7 steps. For adults, 6th stage small, 6 and 11 years old, 5th stage small, 5 and 10 years old, 4th stage small and 4 years, 9 years old, 3rd stage small and 3 years, 8 years old It is possible for elementary school students to play badminton under the conditions of the same net difference ratio as adults.

Invention effect

    As mentioned above, after reforming the net post, we placed it in each gymnasium, and depending on the height of the post according to the age of elementary school age, it is now possible to correctly hit a flight that the lower elementary school students cannot hit until now. Badminton can be enjoyed happily, the number of applicants will increase, and the elementary school will take measures to establish club activities for badminton. The effect of early childhood badminton on the influence of elementary school children's badminton will increase the number of children who are interested in badminton and raise the starting age of badminton. .

In the present invention, the height of the post section for elementary school students can be changed according to their height, and the shuttle can be hit with a certain feeling. If you can relieve your painful badminton, open up a path full of hope, and if many elementary school students are active, various competitions will be held, and excellent athletes in the lower grades will be born. It will be possible to learn and acquire all the skills of badminton in elementary school, and the training period for athletes will be shortened, realizing the realization of early talent development.
Elementary school students 4, 5, 6 can now play an active role in the Tokyo Olympics six years later.

    In addition, the future expectation is that badminton net multi-purpose posts will spread from town to all prefectures, from prefectures to the whole country, Japan will lead the world badminton world, and badminton net multi-function posts combined with elementary school students will spread throughout the world, various International elementary school age-specific badminton tournament will be held, and it will be possible to evolve badminton, create a badminton world for children, and make the world widespread.
