Description

[Detailed description of the invention] The present invention relates to an insole for shoes.

When the temperature and humidity are high, the inside of your shoes gets stuffy, causing bad odors and athlete's foot.

Therefore, the present invention provides an air pump in the heel portion of the insole, so that when the user walks in the shoe with the insole inserted, the air pump provided in the insole is automatically activated.
This device can forcibly supply air to the toe area of the shoe, which tends to get stuffy, and is aimed at eliminating stuffiness and preventing the occurrence of bad odors and athlete's foot.

That is, in the present invention, a deformable air chamber is provided in the heel portion of the insole body, and an air intake port having a check valve for preventing exhaust gas is opened in the air chamber to form an air pump. The gist of this is a structure of an insole for shoes characterized by providing a ventilation path communicating with an exhaust port opening at the toe portion of the insole body.

Next, (1) will be explained according to the illustrated embodiments of the present invention.
is an insole main body, which is configured to be inserted into the inner sole of the shoe (a). (2) is an air chamber, which is provided in the heel portion of the insole body (1). This air chamber (2) can be configured by forming the heel part of the insole body (1) hollow as shown in the illustrated embodiment, or if the air chamber (2) is formed separately and is configured by forming the heel part of the insole body (1) hollow. ) may be configured by being attached to the upper or lower surface of the heel. This air chamber (2) is made of an elastic material such as rubber or synthetic resin so that it can be easily deformed by applying an external force, and can return to its original shape by removing the external force, or can be made of an elastic material such as rubber or synthetic resin. It has a built-in spring. (3) is an intake port, which opens at an appropriate position in the air chamber (2),
Air flows into the air chamber (2) through this intake port (3). (4) is a check valve for preventing exhaust, and the air chamber (2)
The air intake port (3) is provided so as to be openable and closable with respect to the air intake port (3), thereby preventing air from escaping from the air intake port (3). In this way, by providing the deformable air chamber (2) with the intake port (3) having the exhaust prevention check valve (4), the air chamber (2) forms an air pump. (5) is a ventilation path,
The air chamber (2), which is used to exhaust the air pump, has an exhaust port (2) that opens at the toe of the insole body (1).
6). This ventilation passage (5) is connected to the insole body (
11 may be formed as a double structure with an intermediate hollow part, or the hollow part may be divided as in the illustrated embodiment to form a large number of narrow ventilation passages (5) f51... Furthermore, it can also be constructed from a suitable pipe and buried inside the insole main body (1) or attached to the surface of the insole main body (1). In addition, the exhaust port (6) is connected to the insole body (
1) One or more are provided on the side wall surface or surface of the toe portion.

Since the insole of the present invention is constructed in an upwardly sloping manner, as shown in FIG. When you step on the heel of (1), the air pump formed as the air chamber (2) is pressed, and the air in the air chamber (2) flows through the ventilation path (5).
Exhaust port (6) provided at the toe part of the insole body (11) through the insole body (11)
It is discharged into the toe area of the shoe. Next, when the heel of the foot rises, the pressure on the air chamber (2), that is, the air pump, is released and the air chamber (2) returns to its old state.
The intake port (3), which had been closed by the exhaust prevention check piece (4), opens, and new air is sucked into the air chamber (2), that is, the air pump, to cope with the next step. be able to.

In this way, when using the insole of the present invention, air can be forcibly supplied to the toe area inside the shoe, which gets very stuffy, so it increases the stuffiness inside the shoe and prevents bad odors and athlete's foot from forming. It has the practical benefit of being able to prevent this.

In addition, the materials that make up the insole body include air intake,
You can freely choose anything as long as it drains smoothly, and if necessary, you can use copper wire, antimicrobial agents such as antibacterial agents, deodorizers such as activated carbon, fragrances, magnets, and pressure point stimulation. Agents can also be added freely.

The symbols in the figure are explained as follows. +11 is the insole body (2) is the air chamber (3) is the intake port (4) is the exhaust prevention check valve (5) is the ventilation path (6) is the exhaust port

Claims (1)

[Claims] A deformable air chamber is provided in the heel portion of the insole body, and an air intake port having a check valve for preventing exhaust gas is opened in the air chamber to form an air pump.
