Description

Shoes insole with forced air-circulation function

The present invention relates to an insole of a shoe, and more particularly, to an insole of a shoe capable of forced air circulation capable of forcibly circulating and discharging air accumulated inside the shoe through the insole.

In general, a shoe protects and wraps the foot and is intended for walking. Usually, it consists of an upper that covers the instep of the foot, an outsole that is coupled to the lower part of the upper to support and protect the sole, and an insole that is laid inside the shoe to alleviate the impact of the ground. can be

When walking, the inside of these shoes becomes hot due to the heat generated by friction between the foot and the insole, and sweat is generated from the feet, thereby generating bacteria and odors.

In addition, workers have to wear shoes for a long time in a condition with difficulty in ventilation. When working in a poor environment, the moisture inside the shoes increases and the temperature of the feet increases due to high temperature, which can harm health due to various diseases such as athlete's foot and eczema, or work efficiency. There is a problem of lowering

In addition, there is a problem that may cause discomfort to others.

On the other hand, in the case of general sports shoes, the surface material of the outer skin of the shoe is made of a mesh material or a ventilation hole is formed in the outer skin portion.

However, ventilation is the flow of air due to the difference in air pressure, and the pressure difference does not occur when the foot is in close contact with the inside of the shoe, so smooth ventilation is not achieved or the ventilation power is very insignificant.

Therefore, recently, a shoe having a forced blowing structure in which external air is forcibly sucked into the shoe by using a motor and a fan inside the shoe to be blown into the shoe has been proposed.

However, in most cases, the motor and fan are built-in to the heel part of the sole of the shoe, so there is a problem in that the motor and the fan are broken or damaged due to the impact of the ground when walking.

In order to solve this problem, the present applicant filed and registered No. 10-2082258, "the upper; and the sole coupled to the lower part of the upper; and the foot arch part supporting the foot arch in the middle of the sole of the foot and the front heel based on the arch. In a shoe comprising a; an insole comprising a forefoot supporting the forefoot and a rear foot supporting the heel of the rear, wherein a motor with a fan is provided in the foot arch of the insole, and one end communicates with one side of the fan case accommodating the fan. and the other end is extended and provided with a ventilation path communicating with one or more discharge holes formed in front of the insole, a first tube communicating with the fan case, and one end being detachable from the first tube and buried in the arch part and a suction tube, the other end of which is connected to the cap, and a second tube that communicates with the cap having a through hole while being attached to or buried on the side of the upper, and connected to the motor by a cable to control the motor A control box having a built-in switch and a battery is attached to the instep cover of the upper, so that air is sucked through the through hole of the cap as the fan rotates, and is discharged to the exhaust hole through the suction tube and the air passage. It relates to a shoe equipped with a forced air circulation system.

In this prior art, since the motor and the fan are embedded in the arch part of the insole, even if a pedestrian walks or runs, the foot arch of the foot is arched, so the shock hardly affects the motor or fan, so the motor or fan is not damaged or broken. It had the advantage of excellent durability, and when the insole is separated from the shoe, the suction tube or cable has a detachable structure, so cleaning the insole is easy. could have been prevented

However, some drawbacks have occurred.

First, the second tube for sucking the outside air is attached to the side of the upper or buried. When the second tube is attached to the outside, it protrudes, so there is a problem in aesthetics. In this case, there is a problem in that the upper is thickened.

Second, there is a problem in that the connection portion of the first tube and the second tube is broken or cracked due to continuous walking, so that air intake is stopped. Even if the first tube and the second tube are detachably connected, there is still a problem that the detachable part is damaged.

Third, the structure including the first tube, the cap, and the heating wire on the side of the upper is complicated and difficult to manufacture, thereby increasing the production cost.

Fourth, since the cable is connected via the instep cover or side cover of the shoe upper, it is difficult to separate the insole and the upper, and there is a very cumbersome problem to replace the insole. And there is a disadvantage that the insole cannot be used with other shoes at all.

1 is a plan cross-sectional view showing the structure of the insole of a shoe capable of forced air circulation according to an embodiment of the present invention.

The insole 10 is seated on the upper part of the outsole or midsole inside the shoe, and is intended to absorb shock transmitted from the ground, improve the walking feeling of pedestrians, and minimize fatigue.

The structure of the insole 10 according to the present invention is generally a forefoot portion 10a supporting the forefoot located in front of the sole, a hindfoot portion 10b and a forefoot portion 10a supporting the heel located at the rear of the sole, and a hindfoot portion It may be formed between (10b) and may be composed of a foot arch portion (10c) that supports the arch recessed in the center of the sole.

The thickness of the forefoot portion 10a is relatively thinner than the thickness of the hindfoot portion 10b and the foot arch portion 10c.

And since the hindfoot portion 10b receives the most impact, it is formed to have the thickest thickness.

On the other hand, the foot arch portion 10c has a shape of increasing thickness. In particular, the portion supporting the foot arch formed to be recessed on the inside of the sole may be formed to be thicker.

In addition, the foot arch portion 10c is the portion that receives the least impact compared to the hind foot portion 10b or the forefoot portion. Accordingly, in the present invention, each of the above-described components is built into the foot arch portion 10c.

The present invention will be described in detail with reference to FIG. 2 together. Figure 2 shows a longitudinal cross-sectional view of the present invention shown in Figure 1;

The insole 10 of a shoe capable of forced air circulation according to the present invention includes an inlet and outlet space 100 , a motor 200 , a blower 300 , an exhaust hole 400 , a heating wire 500 , a rechargeable battery 600 , It may be configured to include a controller 800 , a receiving coil 610 , and an ultraviolet lamp 700 .

The inflow and outflow space 100 is formed in the foot arch portion 10c.

That is, the inflow and outflow space 100 may be formed in a rectangular shape, and is not exposed as it is formed to be buried in the foot arch portion 10c.

And the inlet and outlet space 100 is formed with an inlet 110 through which air can be introduced by communicating with the side of the foot arch portion 10c on one side so that air flows in and out.

And on the other side, in other words, in the direction of the forefoot 10a, the outlet 120 is formed in communication with the blower 300 through which air can flow out.

The motor 200 is installed inside the inlet and outlet space 100 . In addition, the fan 210 may be coupled to the shaft of the motor 200 to be rotationally driven.

At this time, in order for the fan 210 to rotate freely, a constant space must be maintained so that the inflow and outflow space 100 is not compressed or reduced. can The case may have a rectangular shape or a cylindrical shape corresponding to the shape of the fan 210 .

Naturally, the inlet 110 and the outlet 120 should also be formed in the housing.

Preferably, the fan 210 may be disposed to face the inlet 110 to facilitate the inflow of air.

In addition, the motor 200 can control the rotation speed and rotation direction, and uses a small size. The motor 200 may also be fixed inside the case or designed to be built in a separate motor case (not shown) to prevent damage.

One or more discharge holes 400 through which air can be discharged are formed on the upper surface of the forefoot 10a.

And the discharge hole 400 is in communication with the inlet and outlet space 100 and the blowing path (300). At this time, the blower 300 is formed from the foot arch portion 10c to the forefoot portion 10a along the longitudinal direction inside the insole.

That is, one end of the blower 300 communicates with the discharge hole 400 , and the other end is formed to be connected to the outlet 120 .

The blower 300 may be provided in a hollow state by molding with an insert inserted when molding the insole, but in order to prevent the flow path from being clogged as the blower 300 is crushed by pressure during walking, the blower ( 300) may be separately inserted into a resin blowing tube (not shown).

With this structure, when the fan 210 rotates, the air inside the shoe is sucked into the inlet 110 , and the sucked air flows out through the outlet 120 , and the leaked air passes through the blower 300 . The internal air is circulated in such a way that it is discharged back into the shoe through the discharge hole 400 .

Meanwhile, the heating wire 500 is inserted into the blower 300 .

The heating wire 500 generates warm air by heating the air flowing through the blower 300 .

The heating wire 500 may be installed in a manner to be accommodated in the blower 300 or may be provided in a manner to be wound around an outer circumferential surface.
