  The shoe with a ventilation function according to a sixth aspect is characterized in that, in the ventilation path, a support is provided in the ventilation path.

  As described above, the ventilated shoe according to the present invention compresses the cavity provided in the heel part of the shoe due to the pressure applied to the heel part during landing and causes a pumping action. The air pushed out through the air passage provided between the insole and the bottom of the bottom, forcibly injects the air from the injection hole to the bottom of the foot, thereby improving the air permeability, resulting from the stuffiness of the feet and the stuffiness of the feet It contributes to the elimination of malodor and the reduction and prevention of symptoms such as athlete's foot on the toes.

  In addition, the ventilated shoe according to the present invention has a simple structure in which a hollow portion and a vent are provided in the heel portion, an air passage is provided between the insole and the outsole, and an injection hole is provided in the insole. And can be manufactured inexpensively.

  Embodiments of the present invention will be described below with reference to the drawings.

  FIG. 1 is a schematic cross-sectional view showing a first embodiment of a shoe with ventilation function according to the present invention. The upper part 1 of the shoe is the same as a normal shoe, but a hollow part 3 having a pump function is provided in the heel part 2, and a ventilation path is provided between the insole 4 and the bottom 5 toward the toe from the hollow part 3. 6 is provided. The insole 4 is provided with an injection hole 7 for injecting air from the air passage 6 into the shoe.

  On the rear surface of the cavity 3, there are provided a first vent 8 for allowing air to flow into the cavity 3, and a first vent valve 8 a for preventing leakage of air from the first vent 8 to the outside. .

  Furthermore, on the upper surface of the cavity portion 3, a second ventilation port 9 leading to the ventilation path 6 and a second ventilation valve 9 a are provided to prevent the backflow of air flowing out from the second ventilation port 9 to the cavity portion 3. . The air that has flowed out of the second vent 9 flows through the vent 6 and flows into the injection hole 7.

  Although not shown in particular, it is preferable to install the support body to such an extent that the ventilation in the ventilation path 6 is not hindered in order to prevent the ventilation path 6 from being blocked by a load or the like when wearing shoes.

  FIG. 2 shows a landing state when walking while wearing shoes with ventilation function according to the present invention. Normal walking is performed by repeating the operation of landing from the heel and kicking off with the tip of the toe. When walking with the shoes according to the present invention, the internal cavity 3 is compressed by the pressure applied to the heel 2 that occurs during landing. The compressed air in the cavity 3 does not leak to the outside from the first vent 8 because of the first vent valve 8 a, the second vent valve 9 a opens, and the vent 6 passes through the second vent 9. It is pushed out and flows out, and is injected from the injection hole 7 into the shoe.

  FIG. 3 shows a state at the time of departure when walking with the breathable shoes according to the present invention. Since the heel portion 2 is separated from the ground at the time of departure, no pressure is applied, and the cavity portion 3 recovers its original volume. At that time, since the atmospheric pressure in the cavity 3 drops for a moment, a pumping action that causes air to flow into the cavity 3 occurs due to the difference in atmospheric pressure, thereby opening the first ventilation valve 8 a and opening the first ventilation port 8. The cavity 3 is filled with air again. Since the second ventilation port 9 connected to the ventilation path 6 is blocked by the second ventilation valve 9a, the air does not flow backward from the inside of the shoe to the cavity 3.

  FIG. 4 is a plan view showing a state in which the upper part 1 of the shoe with ventilation function according to the present invention is removed. In order to further improve the breathability in the shoe, a plurality of ventilation paths 6 can be provided as shown in the figure.

  The shapes of the first vent valve 8a and the second vent valve 9a are not particularly limited to those illustrated as long as the shapes do not hinder the above-described air flow. Further, regarding the installation positions of the two ventilation valves, the first ventilation valve 8a is optimal on the rear surface of the heel part, but the second ventilation valve 9a is not particularly limited as long as the second ventilation valve 9a is on the upper surface of the cavity part.

  The material of the heel portion 2 is not particularly limited as long as it is a material having elasticity that can compress the inside of the hollow portion 3 at the time of landing and can eliminate the compression at the time of landing. For example, even a rubber material that is also used for ordinary shoe soles can increase or decrease the pressure in the cavity 3, so that the shoes according to the present invention can be manufactured without using any special material. Can do.

  FIG. 5 is a schematic cross-sectional view showing a second embodiment of the shoe with ventilation function according to the present invention. In the second embodiment, only the first ventilation valve 8a is installed. In this case, since there is no second ventilation valve, a backflow of air from the injection hole 7 to the second ventilation hole 9 occurs at the time of departure, but this does not impair the breathability in the shoe. Installation omission is possible.

  FIG. 6 is a schematic cross-sectional view showing a third embodiment of the shoe with ventilation function according to the present invention. In the third embodiment, only the second ventilation valve 9a is installed. Even in this case, since the cavity 3 is compressed by the pressure at the time of landing, an air flow to the ventilation path 6 is generated, and the air is injected from the injection hole 7.

  FIG. 7 is a schematic cross-sectional view showing a fourth embodiment of the shoe with ventilation function according to the present invention. In the fourth embodiment, the first vent valve and the second vent valve are not installed, and the diameter of each vent is reduced as compared with the case where the vent valve is installed, so that the inflow of air into the cavity 3 and the injection hole Air is injected from 7 into the shoe.
