Abstract

The present invention relates to an EVA training aid which can be used for a variety of training according to the number of holes in order to concentrate and motivate the children to exercise in Taekwondo and various exercise training courses and to provide motivation for children to exercise easily and have fun And to improve the quality of the resultant exercise.
EVA can be used only in the gym. It can be used not only at gymnasium to learn exercise but also at home and at any place. EVA can be used regardless of the place and place. Of course, there are features that can maximize the effect of exercise by using various strengths according to the size of the hole and polishing the various techniques with the exercise equipment using the resistance of the wind and using it according to the age and training level of the children.

Description

Depending on the number of holes, EVA equipment that can be leveled can be provided depending on the number of holes.

The present invention relates to an EVA training aid which can be used for various training according to the number of holes in order to concentrate and motivate the exercise to the children in Taekwondo and various exercise training courses.

I will explain the background technique as an example of Taekwondo training because it is a product mainly used when exercising with children. In Taekwondo training, there is a program to turn on candles and regulate the candles to help children to concentrate. However, candles are too dangerous for children to take out at any time, and they are too dangerous to control themselves, and there are disadvantages that only a limited number of programs can be applied other than candlelight.

While thinking about what could be used to bring down the wind, I used EVA material as the material of the bottom of the gym. I made it down to the shape of zeolite, and I realized that the material was so lukewarm that it fell well in the wind.

As mentioned earlier, I tried to apply the EVA size and thickness to the training activities of the children by varying the size of the zeolite at first, but it falls down differently according to the power and the technology, but it is like a candle in terms of speed and technology, And the limits of the candle.

So, as shown in the drawing below, I made a hole using the rank of the army in the same size, and applied the steps of the taekwondo belt of the children according to the shape of the class.

As a result, depending on the number of holes, the wind resistance is different, and the band and age of the children can be distinguished and utilized variously.

It aims to motivate children to exercise easily and funly and to improve the quality of the resultant exercise.

Lightweight, easy-to-carry features and a variety of thicknesses and holes help children to concentrate and adjust their strength according to the size of the hole, polish a variety of techniques, increase their interest and improve the quality of their workouts. There is purpose to see.

The present invention utilizes a material called EVA which can produce various shapes and is not subject to any particular place, and it is a training product using strength of strength and resistance of wind with different number of holes. It is possible to maximize the effect of exercise by using variously.

[Figure 1] The shape of the invention as seen from above and from the side
[Fig. 2] and [Fig. 3] show an example of a hole
[Fig. 4] is an invention that can elevate inventions 1, 2, and 3 on a box, adjust the height according to the technique, and store inventions 1, 2, and 3.

The present invention will now be described in detail with reference to the accompanying drawings.

[Figure 1] is an ethylene-vinyl acetate (EVA) pre-assembly drawing.

(A) The main body is 3.5cm in width, 5.5cm in thickness and 0.3cm in thickness. (B) It is a figure that can insert the body which is 4.5cm in width and 1cm in thickness and 0.6cm in thickness.

(C) and (d) are front and side views of the finished product.

[Fig. 2] is a step-by-step drawing with a hole made by the rank of the army and made in 9 steps according to the grade of Taekwondo. (A) The picture is 3.5cm in width, 5.5cm in thickness, The lowest level is 1cm thick and 0.6cm thick.

(B) is the same size as (a), and it is 2cm in width and 0.5cm in width in the main body, and the resistance of wind is reduced to increase difficulty.

(C) The figure is the same size as (A), and the number of holes is increased to two.

(D) and (E) Picture also increased the number of holes, and increased the thickness to 0.4 cm to give more difficulty.

[Fig. 3] changed the size and thickness as an intermediate stage of Taekwondo class.

Body width 5cm Length 7.5cm Thickness 0.5cm Thickness 6cm height 1.3cm Thickness 0.7cm Thickness, to give the fun, I changed the shape of the hole for fun.

(B) The diagram is the same size as (A) and the number of holes is increased to 2. We increased the thickness of the body to 0.6cm, and made the difficulty by increasing the number of holes.

Fig. 4 (a) - (d) is a photograph of the side, Fig. 4 (a) is a bottom view, (b) It is finished picture.

(Outer box height of about 70 cm, inner box of about 65 cm, [Figure 4] horizontal, vertical 30 cm)

As a supplementary explanation for the assembly in the above figure, 1 in (A) is the height adjustment hole, and 2 and 3 are the parts that fit in the hole of 4 on the other side.

The second stage 2 was slightly larger than the hole to prevent it from being pulled out at the same time as it was inserted, thereby preventing the second stage 2 from being easily released.

(G) is a device that inserts into the height adjustment hole.

(A) is a completed picture of the outer box.

[Fig. 5] is a sagittal line, 1 of (A) is inserted in 7 of Fig. 4 , and 2 is a hole into which 6 is inserted. 4 is fitted in the 3 frame. 5 is the hole where 8 is inserted.

(G) is a complete picture of the in-box assembly.

[Figure 6] can be used by putting the hand into the hole of 8 in [Figure 4] and raising the torso by one step and using the invention shown in Figure 2 as standing up.
