Description

Ventilating device for shoes using midboard

The present invention relates to a shoe ventilator, and more particularly refers to a board that enters between the midsole (midsole and insole) is installed on the bottom of the shoe. It is commonly referred to as "texon" in the industry] to efficiently discharge odors and moisture generated in the shoes to the outside, and ultimately to smoothly ventilate the inside of the shoe shape and fit when wearing shoes It is to provide a shoe ventilation system using a midboard that can greatly contribute to maintaining health.

Conventionally, a number of proposals have been made on shoes ventilators having midsoles for midsoles to remove odors and improve fit by promoting smoothness of ventilation when wearing shoes.

However, as is well known, the conventional ventilation device for shoes allows the air to be supplied to the inside of the shoe by the stepping pressure during walking, thereby smoothing the ventilation on the inner side of the shoe with poor air circulation. It was to minimize the odor caused by the secretions such as sweat and to remove the accumulation of moisture to increase the fit.

However, in the case of such a conventional shoe ventilator there is a limit to the removal of moisture due to the secretions such as sweat generated from the inside of the shoe by supplying air to the inside of the shoe.

That is, even if the air is supplied to the inside of the shoe, the air is mainly supplied to the sole part of the wearer so that it takes a considerable time for the moisture to be released to the outside through the upper part. Nevertheless, it was not able to provide smooth breathability, and it takes considerable time to remove moisture. Especially when enjoying various sports such as rainy season, water has penetrated into the shoes, causing significant obstacles in walking and running due to slipping. It has been induced.

Therefore, the present invention provides a shoe ventilator, but water due to sweat generated inside the shoe, as well as the water penetrated into the shoe gap during the rainy season can be forcibly discharged to the outside by the stepping pressure during walking. The technical problem of the invention is to provide a shoe ventilation system using a midsole that can ultimately improve the breathability inside the shoe by providing a means to improve the wearing comfort, thereby significantly maintaining the health of the foot. The present invention has been completed.

1 is a cross-sectional view showing a preferred embodiment of the shoe ventilator provided in the present invention, as shown in the midsole (2) is usually attached to the outer end portion of the shoe (1) inside The upper and lower divided bodies (3,4) to form a chamber (5) inside the midsole (2) by integrating it using a thermocompression or adhesive at the outer end.

The front side of the chamber 5 formed inside the midsole 2, that is, the portion where the front side of the foot is in contact with the shoe formed a plurality of inlet holes 6 in the upper portion, the chamber in communication with the inlet hole 6 The first chamber 5a is formed on the front side of the chamber 5 by using the partition wall 7 so as to be distinguished from the second chamber 5b formed in the middle and rear parts of the chamber 5, but the partition wall 7 The one-way check valve 8 is installed in the air to check the air and moisture inside the shoes introduced through the inlet hole 6 to the second chamber 5b only by the stepping pressure during walking in the first chamber 5a. It can be moved through the valve (8).

In addition, a plurality of cushioning protrusions 9 are formed in the second chamber 5b, and when the shoe wearer walks after wearing the shoes, the cushioning protrusion 9 contracts and stretches up and down, and the second chamber 5b is provided. Allow the body to stretch in volume.

On the lower end of the rear side of the second chamber 5b, that is, on the divided body 4 at the lower portion, a one-way check valve 10 for discharging air and moisture to the outside is provided, and the discharge hole opened to the lower side of the shoe 1. Communicate with (11).

And the reinforcing core 12 is attached to the bottom of the divided body 4 of the lower portion. Among the upper and lower divided bodies 3 and 4, the upper divided body 3 is preferably made of a material having excellent elasticity, and the lower divided body 4 has a material that is harder than the upper divided body 3. It is good to choose.

In the drawing, reference numeral 13 denotes an upper part of the shoe 1, and 14 denotes a midsole and an outsole part of the shoe 1.

Shoes ventilator using the midsole of the present invention that can be configured as described above is fixed integrally with the upper part constituting the shoe (1), and to be worn by placing the insole on top of the shoe, the present invention is applied (1) to quickly discharge the moisture generated inside the shoe (1) and the resulting odor generated by the stepping pressure generated when walking after wearing (1) to the outside of the shoe (1) at all times Inner, in particular, the inner side of the shoe is less breathable intensively breathable and can be excellent in comfort, look at the effect thereof in more detail as follows.

In other words, when the user walks after wearing the shoes 1, the stepping pressure during walking acts on the upper divided body 3 of the midsole 2 of the present invention, and the upper and lower divided bodies 3 and 4. The cushioning protrusion 9 formed on the second chamber 5b which is formed in the middle part and the rear part of the middle part is biased and contracted downward due to the stepping pressure, which causes air and moisture to stay on the second chamber 5b. The back is discharged to the outside of the shoe 1 through the check valve 10 and the discharge hole (11), the pressure applied to the second chamber (5b) is removed when the pedestrian moves the foot cushion ( 9) is returned, whereby the internal volume of the second chamber 5b is extended and air and moisture, etc. on the first chamber 5a are transferred to the second chamber 5b through the check valve 8 by the suction force at this time. Flows into.

Of course, several inflow holes 6 are communicated with the inner front side of the shoe 1 in the first chamber 5a. After the suction is transferred from the first chamber 5a to the second chamber 5b as well as the generated water as well as the moisture introduced from the outside, the next walking pressure is applied to the second chamber 5b to quickly check the valve as in the case of electricity. It is discharged to the outside of the shoe (1) through (10).

As described in detail above, the present invention actively discharges odors and moisture due to sweat generated when shoes are worn inside the shoes 1, and moisture introduced from the outside by stepping pressure during walking. By doing so, it is possible to eliminate the health risks of the foot due to the internal moisture and bad smell of the shoes, and in particular, it is possible to discharge the moisture introduced into the shoes very efficiently when enjoying various sports, such as rainy season, and slips. It is a very useful invention that can prevent the phenomenon of the back and make the interior of the shoe in a comfortable state, and can greatly contribute to the function as a shoe with the improvement of wearing comfort.
