Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention promotes the health of the foot by the function of sending fresh air into the shoes by a separate ventilator and discharging the odorous gas inside the shoes to the outside, and thus the health of the whole body. For profitable shoes.

[0002]

2. Description of the Related Art In today's world, people's life in terms of material has been improved more and more with the increase of national income, and accordingly, shoes having various ventilation functions according to the needs of the people have been devised and developed. However, the human foot bears the weight of the whole body, and in particular, in exercises such as high jump, long jump, or running, all the loads due to the exercise generated during exercise are applied to the feet in addition to the weight. So there is an increasing need for shoes that are flexible and elastic to reduce the strain on the foot.

[0003] Conventionally developed shoes having a ventilation function are provided with an air-filled space at the bottom of the shoes, a mechanism is arranged under the shoes, and the pressure of the raising and lowering of the feet at the time of running or exercising, A method is adopted in which air in the air-filled space is sent into the shoe, or air in the shoe is suction-filled in the air-filled space. Since such a ventilation device is an exchange of air in the shoe and cannot improve the convection effect of the fresh air, it is difficult to bring the inside of the shoe to a comfortable dry state.

[0004] Another conventional technique is to sufficiently exchange air between the inside and outside of the shoe by using a device in which an air bag is provided on the inner bottom of the shoe and a check valve is provided.

[0005]

However, the above-mentioned air sac device is directly formed integrally with the shoe on the inner bottom of the shoe and is fixed, so that a ventilation effect can be obtained by the pressure of both feet applied to the shoe during exercise. However, this structure makes it difficult to fix the shape of the periphery of the bottom of the shoe, and cannot bear a tensile force or a bending force during exercise. Also, because the hollow air bag in the center of the shoe insole is relatively soft,
The periphery of the midsole is thicker and harder than the air sac. Thus, the moment the foot reaches the ground, the amount of weight applied to the air sac is small, and most of the weight is concentrated on the relatively hard part of the inner bottom edge, which increases the chance of causing injury to the foot. Further, the air sac portion has a structure supported by the hard peripheral edge of the above-mentioned middle bottom portion, so that it is difficult to compress the air sac portion, so that a sufficient ventilation effect cannot be obtained. Furthermore, in the related art where the complicated structure of the ventilation valve has not been improved, it is difficult to reduce the volume of the ventilation valve, and a satisfactory ventilation shoe has not yet been developed.

A main object of the present invention is to provide a shoe with a detachable ventilation device, in which a ventilation device is separably fitted to the bottom of the shoe, and when the weight of the whole human body is loaded on the periphery of the middle bottom, the periphery of the middle bottom is provided. Without supporting the air sac,
Therefore, at the moment when the toe is bent, the air sac is forcibly bent to compress the internal air, thereby generating a pump-type ventilation action for sending air into the shoe.

Another object of the present invention is to provide a shoe with a separate ventilating device, whereby the ventilating device can be arbitrarily attached and detached and washed to maintain cleanliness and hygiene in the shoe, and the vent holes of the vent valve can be easily formed. Solve the problem of blocking,
It is another object of the present invention to reduce the volume of the ventilation valve to a minimum to reach a complete implementation stage and to prevent the hardness and thickness of the ventilation valve from constituting an obstacle to toe movement.

Still another object of the present invention is to provide a shoe with a separate ventilator, whereby fresh air is introduced into the air bag from the outside of the shoe by the action of a check intake valve and a check exhaust valve. To keep the air in the shoe fresh, and the intake and exhaust valves are also inserted into the air sac in a separable manner, so that they can be attached or detached as necessary or reinserted in the opposite direction In this way, the path of intake and exhaust can be changed to prevent rainwater or cold air from being sucked into the shoes during rainfall or winter.

[0009]

In order to solve the above-mentioned problem, the present invention provides a shoe according to any one of claims 1 to 4.

[0010]

The present invention relates to a ventilator having a closed hollow air bag and a check intake valve and a check exhaust valve, wherein an intake valve and an exhaust valve are arranged so as to be separable on one of the air bags. As the air intake / exhaust means, the above-mentioned ventilation device is detachably fitted into the recessed tub in the almost front half of the inner bottom of the shoe, and when the user bends the toe by exercise such as walking, the air sac is compressed. By sending fresh fresh air into the shoes and ventilating, and the ventilation device can be removed and washed as desired,
You can keep your shoes clean and hygienic.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
A closed hollow air bag 30, two insertion holes 31-31 disposed in the air bag 30, and a vent hole 32-3 provided in the bottom thereof.
2 is provided. In addition, one vent valve 100, 200 having the same structure is separably inserted into the insertion holes 31-31 of the air bag 30 in the state of acting in opposition to each other.
The check intake valve 100 that can flow in one direction and the check exhaust valve 200 that can flow in one direction are formed by the combination with the two vent holes 32.

The air sac 30 has an elliptical shape, and the wall film in the central portion thereof is made slightly thin (see FIG. 4) to enhance the elasticity of the return and to save the bending, so that the air sac 30 may be walked or exercised. At that time, the air bag 30 is bent due to the bending of the toes to cause a pump-type compression action, so that rapid ventilation in the shoe is performed. In addition, since the above-mentioned bending operation occurs inside the air sac, it does not cause a movement disorder for the toes, and the safest use for the user is guaranteed.

Next, as shown in FIGS. 6 to 10, the vent valve 100 (200) of the present invention is constituted by a hollow elongated outer tube body, one end of which extends inward and has a slightly smaller inner layer. A tube 112 is formed, and a gap 113 is formed between the inner tube 112 and the vent valve outer tube 111 to form an inner tube 120.
Can be fitted. The inner pipe 120 is provided with a circular valve body 130 according to the length of the inner layer pipe body 112. A part of the periphery of the valve body constitutes a hinge 131 with the inner pipe 120, and the other part is a free periphery. (Figs. 9 to 10)
reference).

By making the outer diameter of the valve body larger than that of the inner tube 112, the end of the inner tube 112 is
0 so that only one of them can be opened and closed (see FIG. 6) to form a check vent valve having a simple structure. The ventilation valves 100 and 200 operate in opposite directions to each other so that the insertion holes 31-
Since it is inserted inside 31, a check intake valve 100 and a check exhaust valve 200 are formed in the air bag portion (see FIG. 5A). The air introduced from the intake valve 100 is sent into the air sac 30, and when the air sac 30 is bent by compression, the air inside is pushed out and discharged from the check exhaust valve 200 into the shoe.

As shown in FIG. 1, the exhaust device 3 of the present invention.
0 is separably fitted on the shoe bottom 20. An elliptical concave tank 21 is provided in the center of the front half of the bottom 20 to accommodate the ventilation device 30, and an intake hole 22 penetrating to the outside of the shoe is provided at a position where the concave tank 21 corresponds to the intake valve 100. By disposing the exhaust groove 23 at the other end of the concave tank 21 at a position corresponding to the exhaust valve 200, which bypasses to the heel part, the air bag 30 is compressed by the bending motion of the toes for ventilation, Sucks fresh air from the outside of the shoe through the intake valve 100, discharges the fresh air into the exhaust groove 23 through the exhaust valve 200, and further provides the fresh air corresponding to the exhaust groove 23 of the inner shoe sole 40. By being sent into the shoe through a large number of exhaust holes 41, fresh air is continuously sent into the shoe for ventilation.

The intake valve 100 and the exhaust valve 200 are separably inserted into the insertion hole 31 of the air sac 30, and can be removed and washed arbitrarily to maintain good air permeability. Because it is easy, even if the volume of the ventilation valve is reduced to a minimum, there is no danger of clogging. If it is a cold day or if it is raining, remove the ventilation valve and insert it in the opposite direction.The original intake position will change to the exhaust valve, and the original exhaust position will change to the intake valve. As a result, the air in the shoe is discharged from the ventilation hole 22 to prevent the cold and moist air from being directly sucked into the foot on a cold day.

Next, a first embodiment of the present invention will be described with reference to the drawings.

As shown in FIG. 1, the shoe according to the present invention is provided with a shoe bottom 20 and an inner bottom 40, and an elliptical concave tank 21 and an intake hole 22 in front of the inside of the bottom 20.
The concave tank 21 communicates with the outside atmosphere through an intake hole 22. Further, a groove 23 is provided so as to extend from the concave tank 21 to the heel portion of the bottom portion 20. The concave tank 21 is provided so as to be located below the toe portion when the user wears the shoes of the present invention. The reason will be described in detail later.

As shown in FIGS. 4 and 5A, a substantially oval-shaped air bag 30 is installed in the recess 21 in a separable state, and the air bag 30 is made of a material having elasticity. I have. The air sac 30 is provided with an insertion hole 31 and a ventilation hole 32, and the upper wall 321 of the air sac 30 is configured to be slightly raised, and the wall film of the upper wall 321 and the lower wall 322 is formed. Is thinner than the peripheral edge so that it is easy to bend and has better elasticity.

Next, as shown in FIG. 1 and FIGS. 5B to 5C,
The check intake valve 100 and the check exhaust valve 200 are detachably inserted into the insertion hole 31 and the ventilation hole 32, respectively. Although the structure of the intake valve 100 and the exhaust valve 200 is completely the same,
It is inserted so as to have opposite effects. Intake valve 100
Sends air outside into the air sac 30, and the exhaust valve 200 has a function to discharge air inside the air sac 30 into the inside of the shoe.

As described above, the intake valve 100 and the exhaust valve 200
Have the same structure, and the structure will be described using the check intake valve 100 as an example. As shown in FIGS. 6 to 10, the valve 100 includes an outer tube 110 (see FIG. 8) and an inner tube 120 (see FIG. 9). An inner tube 112 is provided, and an end of the inner tube 112 is connected to be integral with one end of the outer tube 111. The outer tube 111 is disposed on the inner tube 112 with a gap 113 therebetween.

The inner tube portion 120 is composed of an insertion tube 121 and a valve body 130 connected to the inner tube 120 by an elastic hinge 131, and the outer diameter of the insertion tube 121 is made to match the inner diameter of the outer tube 111. Therefore, the insertion tube 121 can be tightly inserted into the outer tube 111.

The width of the gap 113 provided in the outer tube portion 110, that is, the gap between the inner tube 112 and the outer tube 111 is made slightly smaller than the thickness of the wall of the insertion tube 121 so that when the insertion tube 121 is inserted. It can be tightly pinched and fixed in the gap 113.

Since the inner tube 120 is made of a soft elastic material and the outer tube 110 is made of a hard material, the inner tube 120 is fixed to the outer tube 110 when the inner tube 120 is fixed to the outer tube 110.
Thus, the inner tube 120 is supported to prevent deformation due to external influence.

The valve element 130 is made of a circular flat flat elastic material such as plastic. As shown in FIG. 7, after the inner pipe portion 120 and the outer pipe portion 110 are assembled, the valve body 130 is airtightly adhered to the opening of the inner pipe 112 while maintaining elasticity. As shown in FIG. 6, when air flows from right to left, the valve element 130 opens leftward and introduces air into the check valve 100. Further, as shown in FIG. 7, when the air flows from left to right, the valve 1
30 closes the edge of the opening of the inner tube 112 and stops the flow of air.

Next, as shown in FIG. 1, when the air sac 30 is fixed in the recess 21 in the shoe, the intake valve 100 is disposed in the intake hole 22 and the exhaust valve 200 is disposed in the free end of the groove 23. It will be in the state that was done. Since the inner bottom 40 is provided with a large number of pores 41 and the distribution thereof corresponds to the shape of the groove 23, the fresh air sent out from the groove 23 flows into the shoe through the pores 41.

FIG. 2 shows a state where the user is wearing the shoes of the present invention. In the figure, the air bag 30 is provided below the toe part of the shoe. According to ergonomics, when a human raises his foot during a movement of the foot, for example, walking, running or dancing, his toes flex momentarily and then stretch up to leave the ground. At this point, the air sac 30 is simultaneously bent and compressed with the bending of the toes, and the air is squeezed into the air sac and enters the shoe from the guide groove 23 of the exhaust valve 200 through the respective pores 41 of the inner bottom 40.

When the action of the air sac 30 is canceled when the shoes are released from the ground and the toes are straightened, the air sac 30 returns to its original shape due to the above-mentioned special structure and elasticity. .. In the process of restoring the shape of the air sac 30, the outside air is sucked into the air sac 30 through the intake hole 22 and the intake valve 100 by the suction action, and the air sac 30 is just like a pump by the continuous action of the user. By continuously inhaling fresh air into the shoe and then pumping the air into the shoe, the fresh air fills the shoe and the hot air in the shoe is discharged to the outside. With such continuous operation, fresh air is ventilated in the toes of the shoes to promote the health of the feet and, in turn, to the health of the whole body.

Next, a second embodiment of the present invention will be described with reference to FIG. 5D. As shown in FIG. 5D, when the exhaust valve 200 is removed, the ventilation effect is slightly inferior to the first embodiment, but the ventilation function still exists. When the air sac 30 is inflated, air is sucked from the intake valve 100 and the vent hole 32 and enters the inside,
As a result, a small amount of dirty air in the shoe is again sucked into the air bag 30, but most of the other sucked air is fresh air from the outside of the shoe, so the effect of ventilation is sufficient.

Next, a third embodiment of the present invention will be described.

The arrangement of the intake and exhaust valves in the above embodiment is suitable for summer shoes. In other words, the above air intake / exhaust arrangement pumps cold air outside the shoe into the shoe by pumping, and discharges odorous gas inside the shoe outside the shoe. On the contrary, in the case of a shoe used in the case of rain or winter, when the intake valve 100 and the exhaust valve 200 are inserted in the opposite directions, the air originally entering from the outside of the shoe is blocked and the air inside the shoe is conversely blocked. Is discharged to the outside through the air bag 30 by the pump action, and the same purpose of ventilation as described above is achieved.

In addition to the above, as a feature of the shoe with a separate ventilation device of the present invention, in order to maintain the ventilation function of the shoe of the present invention in a continuous manner, the air bag 30 can be separated from the inside of the shoe to be washed, and the intake air is also the same. The valve 100 and the exhaust valve 200 are also configured so that they can be washed separately from the air bag 30. In the above washing operation, when the inner sole 40 is first taken out, the air sac 30 can be easily taken out from the bottom of the shoe. At the time of cleaning, dirt accumulated in the intake valve 100 or the exhaust valve 200 can be similarly removed.

After the above washing or dirt removal, if the air bag 30, the intake valve 100, and the exhaust valve 200 are combined again and mounted in the concave tank 21 of the shoe bottom 20, the pump action and the ventilation function of the present invention are immediately restarted. can do.

[0034]

As described above, the present invention is characterized in that the ventilation device is detachably fitted to the shoe bottom. In addition, the ventilation operation is fast, the pump-type compression action is generated in the air sac by the bending motion of the toes, and the air in the shoes is ventilated to fresh air, combined with the arrangement of the check intake valve and the check exhaust valve. The ventilation can be configured in one direction, so that fresh air can be distributed on hot days and heat can be kept on cold days.
