Description

Air Ventilation device for Shoes}

The present invention relates to a shoe ventilator, and more particularly to a shoe ventilator that performs a sufficient ventilation while providing a simple structure.

In general, shoes have the function of protecting the feet from the outside environment, but also include the reverse function of closing the feet from the outside environment.

In particular, there are kinds of shoes to close the foot to the ankle by the design or the specific purpose, for example, shoes formed with ankle such as basketball shoes.

Such shoes are used not only as a specific purpose for basketball, but also as a generalization by their design, thereby tending to close the feet from the outside too much in everyday life.

In order to solve this problem, many shoes having a ventilation function have been devised, but there is a problem in that the structure is complicated or structural irrationality is expressed.

First, looking at the conditions of the shoe ventilator, the precondition is that the structure is simple.

This is because the complexity of the ventilator structure causes problems in durability and reliability in articles that are constantly deformed by walking, such as shoes.

Next, the discharge port is required to be responsible for rapid discharge close to the contaminated area inside the shoe.

This position is the sole and requires rapid ventilation in the position closest to the sole.

Accordingly, it is preferable to have an exhaust port in the shoe cushion body. Accordingly, when the exhaust port is formed in the shoe cushion, the exhaust port is located in the lower part of the shoe, so that foreign matter, especially water, is prevented from entering the shoe through the lower part. A backflow prevention structure is necessary.

Next, when exhaust is performed, an intake air is required for replenishment of fresh outside air, and foreign matters and the like should be prevented from being introduced through the intake air.

By the way, looking at the conventionally applied, most of the first to achieve a structurally complicated ventilation device.

For example, looking at a shoe having an air circulation function (Application No. 20-2003-0003313), the structure of the ventilator is complicated because the pump is operated by the pressure of the back squeeze and the peripheral parts are added.

The complexity of this structure can be fatal for articles that are constantly deformed by external conditions, such as shoes.

This relates to durability and reliability as described above, which facilitates breakage due to fatigue load and damage to any part causes damage to the entire ventilation system.

Moreover, since the shoes are constantly provided with deformation by walking, it is necessary to ensure durability and reliability with the simplest structure possible.

In addition, this does not provide a structure for quickly discharging polluted air, it simply adopts a way to draw the outside air into the shoe neck area.

Next, there is a problem in the positioning of the intake vents, and the intake vents do not satisfy the condition to be avoided from deformation of the shoes and concealed so as not to damage the appearance of the shoes.

Accordingly, the present invention has been made to improve the above problems, the object of the present invention is to provide a shoe ventilation device that enables a simple and sufficient intake and exhaust.

The present invention for this purpose is to form a plurality of chamber pipes to perform the pumping by the volume change of the shoe cushion body for each zone of the front and rear squeegee, and the intake and exhaust is independently performed, so that a simple and sufficient intake and exhaust is performed. .

In addition, the intake and exhaust line is provided with a check valve to provide the direction of the air flow, the intake is to be connected to the upper end of the protective upper relatively less deformation and can prevent the ingress of water from the outside.

Various changes and modifications are possible within the scope without departing from the technical spirit of the present invention, as well as other embodiments that are equally clear.

Exemplary drawings Figure 1 is a private facility showing a shoe ventilation apparatus according to the present invention, Figure 2 is a side cross-sectional view showing a shoe ventilation apparatus according to the present invention.

The present invention in the ventilation device of the shoe formed with a ventilation line to the shoe worn to at least the ankle area, the front and rear gyrus (A) and rear gyrus (A) of the shoe cushion body (10) is deformed by the action of the foot pressure when walking ( A plurality of chamber pipes 12 are formed in B) to provide a change in volume in accordance with the pressure, which is divided according to the front and rear squeezing zones A and B so that an exhaust port is provided in the shoe cushion body 10. A portion of the chamber pipes 12 formed at the side is connected to an exhaust line 14 which is divided according to the zone, and the other part is connected to an intake line 16 which is formed according to the zone. The intake port 20 is formed on the upper 18 and the rear gum protection upper 18 has a hose 22 connected to the intake port 20 and branched and connected to the intake line 16. Pear on line 14 An intake line 16 a check valve 24 is installed, with which define the direction the shoe ventilation system, characterized in that the check valve 26 to limit the intake direction is installed.

As described above, the present invention provides a shoe ventilation device having a simple structure for performing ventilation by replacing the volume change of the shoe cushion body 10 with a pump according to the pressure applied to the shoe when walking.

The present invention for this purpose, first, the chamber pipe 12 is formed in accordance with the pressure acting on the shoe cushion body 10 when walking.

The chamber pipe 12 is formed in a plurality of pipe shapes on a vertical line of the shoe cushion body 10, and the volume of the chamber is provided by the depth of the shoe cushion body 10 and the diameter of the pipe.

Each one of the chamber pipes 12 is combined to provide the volume of the entire chamber. When pressure is applied to the shoe during walking, discharge by volume reduction is performed and suction is performed when restoring by pressure release.

Here, according to the present invention, the area of the chamber pipes 12 is divided into the front and rear gingham region (A) and the rear gingival region (B).

That is, in consideration of walking, since pressure is sequentially generated in the rear gingival area (B) and the front gingival area (A), the volume change is caused, so that the rear and the front gingival are divided into zones.

For example, when the back squeegee lands, the back squeegee is compressed and exhaust is performed, while the front squeegee zone allows the intake air to be performed while the shoe cushion body is restored.

In addition, since the shoe cushion body repeatedly compresses and deforms, some chamber pipes 12 serve to evacuate and some chamber pipes 12 perform intake in one zone.

To this end, some of the chamber pipes 12 formed for each zone are connected to the exhaust line 14, and the remaining portions are connected to the intake line 16.

On the other hand, since the intake port 20 connected to the intake line 16 is a part to suck the outside air from the outside, it should be a position spaced apart from the bottom of the shoe, which is located in the shoe cushion body 10 is contaminated, in particular the inflow of water Because it is easy.

This is different from the exhaust port, on the contrary, the exhaust port is preferably located on the side of the shoe cushion body in order to quickly discharge the contaminated shoes, and the inflow of water from the exhaust port by the check valve 24 which moves the fluid only in the discharge direction. This is because it is prevented.

The hose 22 connecting the intake port 20 and the intake line 16 should not be interfered by the flow of shoes, and should be in a position that minimizes inconvenience of walking by the hose 22.

Therefore, the upper end of the heel protective upper 18 is a preferred position as the inlet 20.

That is, the heel protective upper 28 is relatively rigid to cover the heel, the hose 22 is less likely to be closed closed by the deformation of the protective upper during walking.

However, when the protective upper 18 is exceeded, the case where the hose 22 is bent by a part of the shoe which interlocks with the ankle occurs, so that the upper end of the protective upper 18 is a preferable position as the intake port 20.

On the other hand, the intake line for both sides of the shoe is also possible, but when the shoe is covered, when the shoes are worn, it interferes with the outer part of the foot, which reduces the fit, and when the hose protrudes out of the shoe, damages the shoe appearance. Concerns arise.

For this reason, the top of the heel protective upper located on the back of the shoe is the most desirable intake position.

Next, the check valve 24, 26 for performing the ventilation according to the pumping action of the shoe cushion body in more detail, as described above, the check valve 24 is installed in the exhaust port to discharge only in the exhaust direction And check valves 26 are provided in the branched hoses 22, which are intake lines, to limit the inflow direction of air in the intake direction.

This is to provide a one-way air flow line to the chamber pipe 12. For example, when explaining the action of the chamber pipe 12 to the front gingham zone (A), the chamber pipe 12 is compressed when the front gingham The air packed here will be exhausted.

At this time, the inlet of the chamber pipe 12 is not completely closed but closed by the toe of the toe which provides sufficient resistance.

Here, when the chamber pipe 12 is compressed, the check valve 24 of the exhaust line 14 opens to the exhaust port side and the check valve 26 of the intake line 16 to close to the inlet port side.

As a result, the exhaust port is discharged while preventing contaminated air from flowing back to the intake line.

Next, when the foot is removed, the shoe cushion body 10 of the front gingival area A is restored while opening the intake line 16 and closing the exhaust line 14.

At this time, the front gum is lifted in the shoe to open the inlet of the chamber pipe 12.

As a result, new air is introduced from the intake line 16, and conversely, the inflow of residual polluted air from the exhaust line 14 is prevented, but rather, the polluted air is sucked into the shoe.

Such intake and exhaust is alternately performed as the ventilator of the present invention is formed separately in the front and rear gingival.

In other words, when the tread of the rear gum is exhausted in the rear gimchi area, while the intake is carried out in the front of the gumchi, followed by the exhaust is carried out in the front of the gumchi and the intake is carried out in the rear.

According to the front and back squeeze, the intake and exhaust of the sequential progress is further weighted in the intake in the shoe, whereby a sufficient intake and exhaust can be performed without installing a separate pump.

On the other hand, since there is a risk of pressing the intake line to the front gingival area when exhausting the rear gingival area, the intake line to the front gingival area needs to be shaped to avoid the area where the back gingival is mainly pressed.

As described above, according to the present invention, a plurality of chamber pipes for performing pumping by the volume change of the shoe cushion body for each of the areas of the front and rear gingiva are formed, and the intake and exhaust are performed therefrom, thereby providing a simple and sufficient intake and exhaust. It works.
