In particular, batting mitt is a kind of training equipment, and is frequently used for kicking practice in Taekwondo or other training grounds.

When using the batting mitt, you can determine how much the intensity of the batting is and how the location of the batting is correct when you practice batting, or you can train to respond quickly to the opponent's attack and quickly attack the opponent during the batting exercise. There is a function.

Usually, the kicking practice mitt is used as a kicking target when kicking in martial arts or taekwondo. It consists of a striking plate and a handle with a foam structure made of a hard material inside and covered with leather. When the coach or leader holds the handle and selects the hitting height and position, and then gives a signal, the practitioner is used to strike the hitting plate with the foot.

However, since the conventional kicking exercise mitt is mostly made of synthetic resin material, when it receives a repetitive hitting force, the fatigue load accumulates, and in the end, it has a short life span such as easily broken or damaged due to deterioration in durability.

In addition, the conventional kicking exercise mitt is a type that measures the impact strength, that is, the power when a blow is applied to the mitt by using the pressure change of the air that reacts when hitting, the air provided in the airbags on both sides of the mitt There is a problem in that pressure is mixed with each other or there is a problem of reflux, and thus it is very difficult to accurately measure power when hitting.

In addition, the conventional kicking exercise mitt has a structurally complicated disadvantage as well as deterioration in appearance, such as difficulty in hose processing, as it is a structure that connects two-stranded hoses extending from the airbags on both sides to the handle portion with a measuring device. .

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

In addition, the kicking exercise mitt includes an air unit 16 as a means for selectively regulating air delivery as well as delivering air between the

airbags

10a and 10b side and the power measuring device 15 side.

The air unit 16 sends air discharged from the

airbags

10a and 10b to the power measurement device 15 through a predetermined path during the blow, thereby causing the power measurement device 15 to generate power corresponding to the blow. It plays a role in enabling measurement.

To this end, the air unit 16 includes a unit plate body 22 made of a square plate shape and slidably fitted into the unit insertion portion 26 of the striking plate 11.

Protrusion pipes 32 communicating with each other are formed on the front and rear surfaces of the unit plate body 22 to protrude back and forth respectively, and the inside of the protruding pipes 32 formed in this way is composed of an air passage 20 and a protruding pipe 32 at the same time. At the end of ), caps 33 each having

air inlets

19a and 19b are mounted.

Further, 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 vertically communicating with the horizontal air passage 20 at this time. It becomes possible.

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

Therefore, the inside air of the

airbags

10a and 10b can escape to the air hose 23 along the path leading to the

air inlets

19a and 19b → the air passage 20 → the vertical hole → the air outlet 21. There will be.

In addition, the air unit 16 includes an air hose 23 as a means for connecting the air outlet 21 of the unit plate body 22 and the input side of the power measuring device 15.

The air hose 23 is a rubber hose, and is installed 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 body 22 through its upper end, and has a predetermined width (a slightly smaller width than the air hose diameter) in the neck plate 14. While being extended vertically in the state of being placed side by side in the hose seating hole 25 formed in a vertically incised shape up and down, connected to the air inlet pipe 34 installed in the handle 13 through its lower end do.

Accordingly, the air exiting the air outlet 21 flows through the air hose 23 and then enters the air inlet pipe 34, and the air at this time can be sent to the input side of the power measuring device 15. There will be.

In this way, the air hoses 23 are installed in parallel with the hose seating holes 25 in the neck plate 14, and the air coming from both

airbags

10a, 10b is used as one air hose 23. By integrating and flowing, it is possible to simplify the overall structure related to the hose piping and at the same time facilitate the installation work of the hose, so that the air hose 23 does not protrude or stretch outwards and fits tightly into the hose seating hole 25 Therefore, the interference problem in use can be completely excluded, and there is an advantage in terms of appearance.

In particular, the air unit 16 includes a check valve 24 as a means to selectively block or pass air from both

air bags

10a and 10b.

The check valve 24 uses a protrusion tube 32 formed in the unit body 22 as a valve body while substantially restricting air flow and a ball 24c that regulates airflow and two O-rings 24a that maintain airtightness. ,24b), and the check valve 24 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 tube 32. It plays a role.

To this end, the O-

rings

24a, 24b are inserted into a ring seating groove 35 formed on the inner circumferential surface of the end portion of the protruding tube 32 and mounted in a structure closed by a cap 33, thus mounted The O-

rings

24a, 24b to be arranged can be disposed along the inner circumference of the

air inlets

19a, 19b formed in the cap 33, while the balls 24c are inside the air passage 20 It is installed to be flowable.

Accordingly, when the air of any one of the

airbags

10a, 10b enters the interior of the air passage 20 through the

air inlets

19a, 19b, the ball 24c at this time is pushed out by the air force, It moves to the other side and is in close contact with the O-

rings

24a and 24b on the other side, thereby blocking the

air inlets

19a and 19b communicating with the

airbags

10a and 10b on the other side.

Eventually, through the position of the ball 24c, only the air coming from either

airbag

10a, 10b can be provided to the power measurement device 15 side, and the phenomenon flows backward to the

opposite airbag

10a, 10b side. Since it is possible to prevent, more accurate measurement is possible.

4 and 5 is a cross-sectional view showing the operating state of the kicking exercise mitt according to an embodiment of the present invention.

4 and 5, when the user strikes the

airbags

10a and 10b in the mitt, the air inside the airbag 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) → through the path of the air guide pipe (29) to the power measuring device (15) Will be sent.

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

In particular, each air sent from the

airbags

10a and 10b on both sides hit each

airbag

10a, 10b because it is individually input to the power measuring device 15 side by the operation of the check valve 24. It is possible to measure power more accurately.

For example, when the user strikes the airbag 10a in 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 to the opposite side, blocking the air inlet 19b through the airbag 10b at the rear.

As a result, the air escaping from the airbag 10a exits the air outlet 21 without being backflowed to the rear airbag 10b and is sent to the power measurement device 15.

Conversely, when the user hits the airbag 10b at the rear of the kick for training, the air in the airbag 10b enters the interior of the air passage 20 through the air inlet 19b, and the incoming air By the force of the ball (24c) is pushed to the opposite side to block the air inlet (19a) through the airbag (10a) of the front.

As a result, the air coming out of the airbag 10b passes through the air outlet 21 without being backflowed to the front airbag 10a and is sent to the power measuring device 15.

As it is selectively interrupted by the air check valve 24 coming out of each

airbag

10a, 10b, it is sent to the power measuring device 15 side, so that the correct power when hitting each

airbag

10a, 10b Measurement becomes 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 secure excellent durability even when subjected to repetitive striking forces. By applying a check valve that can maintain and selectively regulate the air discharged from the airbags on both sides, it is possible to accurately measure the power when hitting through accurate air sorting, and the air discharged from the airbags on both sides is 1 By treating it clean with dog lines, it is possible to simplify the overall structure of the meat and at the same time improve the appearance of the meat.
