If it is not particularly limited, it can be adopted.

In addition, the kick training mitt includes an air unit 16 as a means for selectively regulating air delivery as well as transferring air between the airbags 10a and 10b and the power measuring device 15.

The air unit 16 sends the air discharged from the airbags 10a and 10b to the power measuring device 15 through a predetermined path when the blow is made, thereby causing the power measuring device 15 to supply power corresponding to the blow. It will play a role in measuring.

To this end, the air unit 16 includes a unit plate body 22 formed in a rectangular plate shape and slidably fitted to the unit inserting portion 26 of the striking plate 11.

Protruding pipes 32 communicating with each other are formed to protrude back and forth, respectively, on the front and rear surfaces of the unit plate body 22, and the inside of the protruding pipes 32 formed as described above is formed by the air passage 20 and at the same time, the protruding pipes 32. At the end of the cap is mounted a cap 33 having air inlets 19a and 19b, respectively.

In addition, an air outlet 21 is formed at a lower end of the unit plate body 22, and the air outlet 21 communicates with the air passage 20 by a hole communicating vertically with the horizontal air passage 20. It becomes possible.

In addition, each of the protruding pipes 32 on the front and rear of the unit plate body 22 can be accommodated in each of the front airbag 10a and the rear airbag 10b.

Accordingly, the internal air of the airbags 10a and 10b can escape toward the air hose 23 along the path leading to the air inlets 19a and 19b → air passage 20 → vertical hole → air outlet 21. Will be.

The air unit 16 also includes an air hose 23 as a means for connecting between the air outlet 21 of the unit plate 22 and the input side of the power measuring device 15.

The air hose 23 is a rubber hose, and is connected between the air outlet 21 formed in the unit plate body 22 and the air inlet pipe 34 formed at the upper end of the handle 13.

For example, the air hose 23 is connected to the air outlet 21 of the unit plate 22 through the top thereof, and has a predetermined width (slightly smaller than the air hose diameter) in the neck plate 14. While extending up and down side by side in the hose seating hole (25) formed in a vertically cut up and down form, and connected to the air inlet pipe (34) installed on the handle (13) through the bottom do.

Accordingly, the air exiting the air outlet 21 enters the air inlet pipe 34 after flowing along the air hose 23, and the air at this time can be sent to the input side of the power measuring device 15. Will be.

In this way, the air hose 23 is installed side by side in the hose seating hole 25 in the neck plate 14 and the air from both airbags 10a and 10b is transferred to one air hose 23. The integrated flow simplifies the overall structure associated with the hose piping and facilitates the hose installation, and allows the air hose 23 to fit snugly in the hose seating hole 25 without protruding or hanging outwards. Therefore, it is possible to completely eliminate the interference problem in use, as well as advantageous in terms of appearance.

In particular, the air unit 16 includes a check valve 24 as a means for selectively blocking or passing the air from both airbags 10a and 10b.

The check valve 24 uses the protruding pipe 32 formed in the unit body 22 as the valve body, and the ball 24c which substantially regulates the air flow and the two O-rings 24a which maintain airtightness. , 24b, which selectively opens and closes both air inlets 19a and 19b using the position of the ball 24c installed in the air passage 22 of the protruding pipe 32. It will play a role.

To this end, the O-rings 24a and 24b are inserted into the ring seating grooves 35 formed on the inner circumferential surface of the end of the protruding pipe 32 and are mounted in a structure closed by the cap 33. The O-rings 24a and 24b may be arranged along the inner circumference of the air inlets 19a and 19b formed in the cap 33, while the ball 24c is disposed inside the air passage 20. It is installed to be flowable from.

Accordingly, when the air of one of the airbags 10a and 10b enters the air passage 20 through the air inlets 19a and 19b, the ball 24c at this time is pushed by the air force and It moves in the opposite direction and closes to the opposite O-rings 24a and 24b, thereby blocking the air inlets 19a and 19b communicating with the opposite airbags 10a and 10b.

As a result, only the air from one of the airbags 10a and 10b can be provided to the power measuring device 15 through the position of the ball 24c, and the phenomenon of flowing back to the airbags 10a and 10b of the opposite side is provided. As a result, it is possible to prevent more accurate measurement.

4 and 5 are cross-sectional views showing the operating state of the kick exercise mitt according to an embodiment of the present invention.

4 and 5, when the user hits the airbags 10a and 10b in the mitt, the air inside the airbags according to the volume change of the airbags 10a and 10b is the air of the air unit 16. Inlet (19a, 19b) → air passage (20) → air outlet (21) → air inlet pipe (34) → support connecting pipe (28) → air induction pipe (29) to the power measuring device (15) Will be sent.

Therefore, the power measuring device 15 can measure the power according to the blow based on the pressure of the air coming in, and this power measuring method is the same as the power measuring method of the known power measuring device, so a detailed description thereof will be omitted. Shall be.

In particular, since each air sent from the airbags 10a and 10b of the two sides is individually input to the power measuring device 15 by the operation of the check valve 24, the respective airbags 10a and 10b are hit. The power can be measured more accurately.

For example, if the user hits the airbag 10a on the front of the kick training mitt, the air in the airbag 10a enters the inside of the air passage 20 through the air inlet 19a. By the force of the incoming air, the ball 24c is pushed in the opposite direction to block the air inlet 19b communicating with the rear airbag 10b.

As a result, the air exiting the airbag 10a exits the air outlet 21 and is sent to the power measuring device 15 without being flowed back to the airbag 10b on the rear side.

On the contrary, when the user hits the airbag 10b at the rear of the kick training mitt, the air in the airbag 10b enters the inside of the air passage 20 through the air inlet 19b, and thus the air coming in By the force of the ball 24c is pushed in the opposite direction to block the air inlet (19a) to communicate with the front air bag (10a).

As a result, the air exiting the airbag 10b exits the air outlet 21 and is sent to the power measuring device 15 without being flowed back to the front airbag 10a.

In this way, it is selectively interrupted by the air check valve 24 from each airbag 10a, 10b and sent to the power measuring device 15, so that the correct power when hitting each airbag 10a, 10b is achieved. Measurement is possible.

As described above, in the present invention, by connecting the striking plate and the handle with a flexible metal plate material, it is possible to ensure excellent durability even when subjected to repeated striking force, such as extending the life of the mitt and continue to use the functionality for a long time By adopting a check valve that can maintain and selectively regulate the air discharged from the airbags on both sides, accurate air screening can be used to accurately measure the power at the time of hitting. By cleanly processing the two lines, the overall structure of the meat can be simplified and the appearance of the meat can be improved.
