Description

{Functional sole of a shoe}

The present invention relates to a functional shoe sole, and more particularly, to a functional shoe sole, more particularly, to a functional shoe sole which is divided into cells at the front and back of the outsole, So that air inside and outside the shoe can be naturally pumped by the pumping action due to the reduction and enlargement of the area of the pumping suction cell space when the user performs the walking operation by allowing air to flow in and out and pumping action. Thereby restraining the generation of odor and restricting the growth of germs. In addition, the present invention relates to a functional shoe sole that is capable of always wearing pleasant shoe by suppressing a rise in user's foot temperature during walking, and thereby maintaining foot health.

Normally, shoes are manufactured using leather or synthetic resin which is not well ventilated. Therefore, when shoes are worn for a long time, the inside of the shoe is not heated and ventilated, and moisture is generated by sweat, and mold Resulting in smell of foot or athlete's foot.

In order to solve the above problems, various types of ventilated shoes have been introduced. The air circulation structure of the shoe sole has been introduced as a representative example of these various conventional technologies. The air circulation structure of the shoe sole has been introduced. In the prior art, the pump member is separately installed to circulate the outside air to the sole so that only a part thereof is ventilated. There is a problem that foreign substances such as water easily flow into the shoe so that the inside of the shoe is contaminated.

In addition, a shoe insole using a ventilation hole is disclosed in Korean Utility Model Registration Utility Registration No. 20-218227, which also has a structure for circulating air to the lower portion of the shoe using a pneumatic tube serving as a pumping member, The structure is complicated and natural air circulation can not be performed, and the foreign matter is infiltrated without any restriction, and the air tube to be pumped is located on the heel side of the weight-bearing shoe so that the air circulation of the user's back foot is practically difficult The required cleanliness and functionality of the shoe can not be achieved.

A conventional footwear having a ventilation device has been disclosed. In the above conventional technology, a cushion layer and a check valve means, which function as a pumping function, are formed to distribute air to the lower portion of the shoe. , The structure is complicated, the air flow can not be made naturally, and at the same time, it is not free from the inflow of foreign substances. The disadvantage of the above is that it is located on the heel side of the weight- Air circulation is practically difficult, and there is a problem that the required cleanliness and functionality of shoes are not achieved. Further, by applying a check valve, the structure is complicated, and a separate check valve part is provided, so that there is a problem in that the production cost is increased and the check valve can not function at all when the check valve is broken.

In order to further improve the ventilation device of such a conventional shoe, as disclosed in Korean Utility Model Registration No. 20-0448371 of the Korean Intellectual Property Office, the applicant has formed a pumping space portion formed in front and rear of the outsole, And the external air is introduced into the shoes and discharged to the inside of the shoe.

However, according to the conventional sole of the present applicant, since the pumping space portion is divided in front and rear, the position where the weight of the wearer is pressed is limited, and the pressure for discharging the large area of the pumping space portion through the midsole to the ventilation- There was a problem that was not effective in ventilation.

Further, as the irregular mesh is formed, the pressure due to the pressure of the pumping space due to the body weight of the wearer can not be discharged through the irregular mesh, and is stagnated, causing the pumping space to bulge up and down in a convex manner, A problem has occurred.

Accordingly, it is possible to increase the pressure according to the weight of the wearer and to enable the discharge evenly according to the position where the pressure is applied, so that the internal supply of the outside air is made more smooth, thereby improving the odor removal and ventilation, increasing the antibacterial property, A configuration is required.

1 and 2, the functional shoe sole according to the present invention includes an outsole 100, a ventilating midsole 200, and a topper 400. The outsole 100 includes a suction pumping part 102 formed to be in contact with a ground surface of the outsole 100 and formed to be recessed in front of and behind the upper surface of the outsole 100 so as to communicate with the suction pumping part 102 from the outer circumferential surface, A plurality of one-way check valves 104 are formed.

The suction pumping part 102 forming the outsole 100 is connected to only the front and rear sides of the pumping suction cell formed on the lower bottom surface of the ventilating midsole 200 to be described later by external air sucked in one direction by the check valve 104, The remaining pumping suction cells correspond to the upper surface of the outsole 100, and pumping action is performed in a state where airtightness is maintained, so that the air introduced into the suction pumping unit 102 is formed to flow air according to the pumping action.

On the other hand, a check valve 104 communicating with the ventilating midsole 200 on the side of the outsole 100 is formed in one direction so as to be capable of only sucking the outside air. In order to prevent the liquid such as outside water from flowing into the inside, It is preferable that the check valve is formed with a check valve, a text barrier film, or the like.

The ventilation midsole 200 is positioned on the upper surface of the outsole 100 and communicates with the suction pumping portion 102 of the outsole 100 to allow external air to flow through the check valve 104, 1 and 4, the ventilated midsole 200 is formed by pumping air so that the air is continuously supplied in the front and rear directions, and the sucked outside air is cooled, A bottom portion 210, a pumping partition 220, and a cooling partition 230.

The pumping bottom 210 is recessed inwardly of the lower surface corresponding to the upper surface of the outsole 100 and is partitioned by a plurality of partition walls on the lower surface of the lower surface to form a pumping suction cell 212. When the pumping suction cell 212 corresponds to the upper surface of the outsole, airtightness is maintained. At this time, each of the pumping suction cells 212 is provided with a distribution groove 214 Are formed. However, it is preferable that the flow grooves 214 are formed within a range in which the pressure loss due to the pumping action is not caused by the volume change of the pumping suction cell 212. With such a configuration, the pumping bottom 210 communicates with the suction pumping unit 102 at the front and rear sides of the pumping suction cell 212, so that external air is continuously pumped and supplied during the user's walking, Discharge, pumping, and convection.

That is, the pumping suction cell 212 separates the sole of the wearer's body weight by the diaphragm to form independent cells, and the pumping action due to the expansion and contraction of the cell space due to the pressing force of the weight of the wearer So that the air can be introduced and discharged into the sole. Here, the pumping suction cell 212 forming the independent cells is designed to reduce the pressure drop due to the loss of the internal air, which can be generated when one large area is pressed as in the registered practice of the present applicant, The pressure drop due to the flow of the outside air in the suction cell space 104 is minimized so that each independent cell has one pumping effect so that the whole is gathered to have a more powerful pumping effect. Accordingly, in the conventional art, the air moves to the arch portion side of the foot which is relatively less loaded before the pressure of the pressurized portion reaches the pressure for discharging the air into the sole of the foot so that the pressure is lowered. However, The portion 104 is minimized in the section where the air moves, so that it is easy to reach the pressure at which the air moves to the vented midsole side on the upper side.

On the other hand, in the partition wall constituting the pumping suction cell 212, the flow grooves 214 are formed so that natural convection flows between the independent cells. In this case, the air flowing into the cell space due to a sudden change in pressure due to the action or action of the air of the pumping suction cell 212, which is an independent cell space, So that the full air is discharged to the pumping suction cell 212 by the fine pores 232 which will be described later.

1, the flow grooves 214 are formed in the suction pumping portion 102 (not shown in the figure) even though they are not formed in the pumping suction cells 212 corresponding to the suction pumping portions 102 formed on the front and rear of the outsole 100, ) Is possible.

The pumping compartment 220 includes a plurality of pumping holes 222 capable of bidirectional flow so as to suck and discharge air from the buoyant side of the sole to the pumping suction cell 212 along the opposite side of the plantar arch, . Here, the pumping partition 220 may be configured to allow the air in the sole of the shoe to flow into the pumping suction cell 212 or the outside of the pumping chamber 212 through the check valve 104 of the suction pumping part 102, Air is formed to flow through the ventilation midsole 200 into the shoe sole according to the pumping action of the pumping suction cell 212 by the walking operation. That is, the inner air whose temperature has been raised by the wearer is introduced into the pumping suction cell 212 and is in contact with the outside air to be cooled or convected to be replaced, so that a more comfortable sole can be worn.

As shown in FIG. 6, the pumping hole 222 is formed on the side of the toe, which is the main part of the wearer's sweat or foot temperature rise, so that the outside air cools the toe side, So that the introduced outside air is discharged through the through holes formed in the uppers, which will be described later, so that the flow of the air continuously flows to the upper through the outsole to cool the air.

The cooling partition 230 is formed on one side of the pumping partition 220 and the air supplied by the pumping hole 222 of the pumping partition 220 is discharged at a high flow rate to cool the user's foot temperature The micro pores 232 are formed. As shown in FIG. 5, the micro pores 232 combine the outside air introduced into the pumping suction cell and the inside air introduced into the pumping suction cell through the wearer's walking motion, So that the air filled in the pumping suction cells is discharged at a high flow rate into a narrow space of the fine pores 232 to be escaped by colliding against the diaphragm. Accordingly, the velocity, pressure, and pressure of the fluid by Bernoulli's theorem, The temperature of the shoe sole is lowered based on the fact that the temperature drops as the pressure increases as the flow rate increases through the relationship of height.

The upper part 400 protects the wearer's feet and is coupled along one side of the upper edge of the outsole 100 and is provided to surround the outside of the user's feet and is supported by the ventilation midsole 200 through the insole 300. [ A plurality of through holes 402 are formed on one side of the outer surface of the user's foot so that the discharged air and the outside air flow.

As shown in FIG. 5, when the wearer walks the front of the sole with feet, the ventilated midsole 200 is pressed to the lower surface of the ventilated midsole 200, The pumping suction cell 212 of the formed pumping bottom 210 is compressed and the contraction pumping suction cell 212 on the heel side is relaxed and the outside air is sucked through the check valve 104, And the air due to the contraction of the pumping suction cell in the front side is moved to the rear pumping suction cell and the pressure of the pumping suction cell 212 on the sole side is increased, As a result, the air is discharged to the pumping holes 222 of the micro pores and the ventilation midsole 200, and the air circulates with a feeling of refreshing feeling on the feet of the wearer.

On the other hand, when the heel comes in contact with the foot, the circulation of air is performed in the opposite direction to that described above, and the air having the raised temperature through the pumping hole 222 is sucked into the pumping suction cell space 104 Cooled as it discharges, it is possible to wear more comfortable shoes.

Accordingly, it is possible to divide a portion where the air circulation is not easy due to the conventional pressure drop into independent cells, thereby increasing the pressure applied to each cell, thereby facilitating the circulation of air by the pressure, It is self-evident that it is possible to wear comfortable shoes and to help the foot health.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the scope of the present invention is not limited to the disclosed exemplary embodiments. Various changes and modifications may be made by those skilled in the art, The present invention is not limited thereto.
