Description

[Detailed description of the invention] (A) Industrial application field In the present invention, an insole with a ventilation function is installed inside the shoe.

Using your weight when walking or running, air is forced into the shoes and sweat, which causes stuffiness, is evaporated to the outside of the shoes, keeping the shoes properly dry at all times and preventing the generation of bad odors.
This item relates to a device that keeps the inside of shoes in a healthy condition.

(B) Conventional technology Conventional insoles are made of moisture-absorbing materials and deodorizing materials to eliminate stuffiness and odor from shoes. However, if you use it for a long time, there is a limit to how much moisture it can absorb, so it will get stuffy. Furthermore, the deodorizing effect could not be maintained for a long period of time, and eventually the deodorizing effect almost disappeared. Therefore, conventional insoles had to be replaced periodically.

This was extremely unpleasant for people whose feet tend to get stuffy easily. To relieve this discomfort,
I always had to keep spares on hand and change them frequently, and I always had to use new, dry insoles, which was a financial expense. Manufacturers have been researching this stuffiness and odor and working on developing materials and structures, but they have not been able to solve this problem because it is still not possible to dry the soles of the feet for a long time.

(C) Problems to be solved by the invention First of all, if we consider the root cause of this stuffiness and odor, it is sweat secreted from the feet, and because it is not sufficiently released to the outside, it gets trapped inside the shoes and becomes stuffy. The result is an environment that smells bad and is infested with athlete's foot. This is because the structure of conventional shoes cannot dry even the soles of the soles, and no matter what kind of conventional insoles are used, the moisture absorption limit is eventually exceeded, and the shoes eventually wear out. This invention was created in response to my own needs and the strong needs of many people who have the same problems.

(D) Means to solve the problem Let me now explain its structure.

(a) An air chamber (1) is provided in an elastic hollow insole made of two upper and lower layers.

(b) Provide an air intake (2) in the air chamber.

(c) Provide an air outlet (3) in the front part of the insole.

(d) A cushion (4) such as rubber, sponge, or spring is provided in the air chamber.

The ventilation insole constructed as described above is installed in shoes.

(E) Effects of the invention Next, to describe the effects of the invention, when you take a step wearing shoes equipped with this ventilation insole, your weight is applied to the air chamber (1), and at the same time the air intake (2) In order to block the air, the air in the air chamber is pushed out from the front air outlet (3) to the back of the foot.

The forced air escapes between the fingers and around the feet.

It drains out of the shoe while removing moisture. When you take the next step, your weight shifts from your heel to your toe, blocking the air outlet.

Furthermore, as the heel of the foot rises, the foot moves away from the air intake, and new air is sucked into the air chamber. In this way, fresh air is constantly forced into the soles of the feet and sweat is evaporated, so even when used continuously for long periods of time, the shoes remain appropriately dry, prevent the formation of bad odors, and keep the inside of the shoes healthy. It is possible to maintain it.

In addition, this air insole is not consumable, so it can be used for a long time and reduces the economic burden. Furthermore, as a secondary effect, it has a moderate amount of suppleness, so even if you walk or stand for long periods of time, you will feel less fatigued compared to conventional insoles with less cushioning.

(F) Other Embodiments (A) In the case of deep shoes such as rain boots or basketball shoes, the desired effect can be obtained even if the air intake port is extended from the air chamber and its tip is provided at the upper part of the shoe. Further, the shape of the extending air intake port (5) is made into a single or plural tube shape, or a groove shape.

The desired effect can be obtained by applying double-sided adhesive tape, adhesive, or Velcro to the inner surface of the shoe and using the grooves and holes as air intake holes.

(b) If the air intake port is extended, it will be more effective if one end of it is guided inside the air chamber and when a weight is applied, the extension tube (5) is crushed and acts as a valve to prevent air from flowing back. .

(c) Providing a large number of columnar protrusions (6) or a plurality of groove-shaped spaces (7) on one side of the inner surface of the insole will have a better effect if air circulation is improved.

(d) The same effect can be obtained by using sponge, rubber, or spring for the cushion of the air chamber.

(e) Even if the air chamber is filled with a breathable sponge (8), the ventilation effect can be obtained.

(f) A good effect can be obtained by making the air outlet have multiple holes, or by using a breathable material (9) to blow out widely to the soles of the feet.

(G) Separately make a part corresponding to the air chamber (A) and a part corresponding to the air outlet (B), insert the air outlet of the air chamber from the rear of the air outlet part, and adjust the length to match the shoes. Even if you do it, you can still get the desired effect.

(H) The side of the ventilation insole that comes into contact with the foot is made of hygroscopic material (l
O) Absorbs sweat from the feet, allows it to penetrate into the inside of the insole where air circulates, and allows sweat to evaporate from the inside of the ventilation insole for even greater effects.

(S) Providing an air backflow prevention valve (11) at the air intake provides an even better effect. Also, a cushion is provided below the air intake (air chamber).

Even better results can be achieved by having it act as a backflow prevention valve that blocks the air intake when weight is applied to the air chamber.

(n) Even if only the part corresponding to the air chamber (^) is set up, air is blown out towards the inside of the direct converter.

You can get some effect.

(l) The insole does not have a hollow structure, the lower part is omitted, and instead a slightly harder side part (12) is provided and one plate is placed face down to create a space between the insole of the shoe and that part. Even if an air chamber is provided with an air intake, a cushion, and an air outlet, the effect will be lower, but the purpose can be achieved.

(E) A cuttable part (13) is provided around the insole or at the front and back to adjust the size, so that it can be used as a one-size-fits-all.

(W) It will be more effective if a material with deodorizing effect or antibacterial property is used on the surface of the ventilation insole.
