Description

{INTEGRAL MID-SOLE WITH VENTILATING AND CUSHIONING}

More particularly, the present invention relates to an air-permeable midsole having air permeability and cushion for allowing the air in the midsole to flow outward by repetitive action of compression and uncompression due to pressing of the sole during walking .

In general, the types of shoes include sports shoes that are worn when exercising, shoes worn when worn in clothes or suits, safety shoes worn when working in the fields of machinery and construction, civil engineering, Most of the shoes include a sole that comes into contact with the ground, a midsole that is positioned at the upper portion of the sole to support the foot and improves the feeling of fit of the shoe, and a top that is located at the upper portion of the midsole, And an insole which is placed on the midsole and is seated on the bottom of the upper part to support the sole of the human body.

As described above, in terms of functional aspects according to the types of shoes such as sports, safety, and hiking, the sports shoes and the hiking boots are made of materials for reducing the weight and improving the cushioning property. It has various functions according to the purpose of shoe wear, such as to protect the toe and the foot by inserting a metal plate on the inner front surface of the upper part for the purpose of safety while enduring the impact shock.

In the case of footwear, however, it is not well ventilated because it covers both the soles of the feet, the sides of the feet, the insteps, and the heels. In this case, sweat and moisture from the feet do not evaporate properly. Furthermore, when heat is generated from the feet, the inside of the shoe is made to have a good environment for breeding various bacteriums due to moisture and heat, thereby generating odor, which not only causes discomfort, but also causes eczema and athlete's foot, .

Therefore, it is preferable that shoes of all kinds are provided with good ventilation means.

To this end, Korean Patent No. 10-0733154 discloses a fishbone, that is, a structure similar to a backbone and a rib structure of fish, so that the pressure applied by the sole can be effectively dispersed and accommodated, A shoe sole has been proposed that allows smooth ventilation and thus heat and water exchange using the space between the rib structure and the rib structure, while at the same time making it very easy to manufacture in mass production.

However, the above-mentioned fish-type sole shoe has an excessively emphasized air permeability, so that the contact area with the midsole or the midsole touching the upper or lower surface of the sole is so small that the adhesive such as the bond is not sufficiently applied, .

Also, when the shoe having the fish-type sole is worn when the rain comes, the rainwater enters the space which becomes the ventilation part. In this case, since the rainwater is not easily drained and remains, , Moisture permeates into the shoe, and various bacteria such as eczema and anthracnose bacteria multiply in the shoe, infecting the user's feet.

1 to 6, an integral half-shell 100 including the breathability and cushion of the present invention is interposed between an insole 500 and an outsole 600 of a shoe, A middle cover member 160, a first valve member 200, a second valve member 300, and a ventilation member 400.

The middle window 100 is formed of a synthetic resin material in the shape of a flat plate, and a ventilation hole 111 is formed in an upper portion of the first space 110 formed upwardly from one side.

In addition, the second space 120, which is upwardly recessed from one side of the middle window 100, is divided into the first space 110 and the partition 121.

The third space 130, which is upwardly recessed from one side of the middle window 100, is connected to the second space 120 and the first air passage 131.

The middle cover member 160 is formed by laminating a synthetic resin sheet such as a TPU and a cloth and the edge of the middle cover member 160 is attached to the edge of the middle window 100 by high frequency welding, The lower end of the space 110, the second space 120, and the third space 130 are closed to seal the spaces of the spaces 110, 120, and 130 from the outside.

An assembly hole 161 is formed in a portion of the middle cover member 160 that covers the third space 130. The air hole 400 penetrates through the assembly hole 161, Will be described with reference to Fig.

The first valve member 200 is an element that is mounted on the ventilation hole 111 and controls air flow to the ventilation hole 111 when a user wearing shoes wears a foot during walking or walking. That is, the first valve member 200 normally closes the ventilation hole 111 and is deformed due to an external force applied by grounding, so that the ventilation hole 111 is opened. Will be described in detail with reference to FIG.

The second valve member 300 is installed in a portion of the second space 120 and functions as a kind of check valve for controlling only one-way flow of air between the first space 110 and the third space 130 I have. That is, the air in the first space 110 flows only in the direction of the third space 130, or the air in the third space 130 flows only in the direction of the first space 110, Will be described in detail with reference to FIG.

The ventilation member 400 penetrates the assembly hole 161 (see FIGS. 1 and 6) formed in a portion of the middle cover member 160 in contact with the third space 130, ) And external space. That is, the third space 130 has a passageway function for discharging the air to the outside or, conversely, for sucking the outside air into the third space 130, which will be described in detail with reference to FIG.

When the ventilation member 400 passes through the assembly hole 161 of the middle cover member 160, the ventilation member 400 and the midsole (not shown) 100) edge, it is possible to prevent a hole from being made in the ventilation member 400 at the time of sewing.

2, 3, and 6, the first valve member 200 includes a base plate 211 having a flat plate shape and being flexible, such as silicone or rubber, A protrusion 213 protruding upward from the supporter 212 to be inserted into the vent hole 111 in a ring shape and protruding upwardly from the supporter 212 to be in contact with the peripheral lower end of the vent hole 111; A second air passage 214 connecting the inner and outer spaces of the ring-shaped ridge portion 213 to the base portion 213 as shown in FIG. And a hole 215 perforated in the vertical direction.

At this time, the periphery where the holes 215 are formed may be the same as the thickness of the base plate 211, and the thickness around the holes 215 is significantly thinner than the thickness of the portions where the protrusions 213 are formed.

The first valve member 200 may be a flexible material such as silicon or rubber, and may be attached to the base plate 211 by an adhesive plate 220 (including adhesive bonding and fusion bonding by high frequency heat) And a cover plate 221 extending from the attachment plate 220 and contacting the hole 215 to open and close the hole 215 according to circumstances.

With this configuration, normally, the cover plate 221 comes in contact with the bottom surface of the hole 215, and the hole 215 is closed, so that the air circulation in the vertical direction is impossible.

On the other hand, when the wearer wears shoes and is grounded, an external force is applied to the upper side of the first valve member 200. At this time, deformation which is distorted by the thickness difference or the step difference around the ridges 213 and the holes 215 occurs The contact between the cover plate 221 and the hole 215 is released so that the air can be circulated through the hole 215 in the vertical direction. Since the upper part of the hole 215 has a space inside the shoe and the lower part has the first space 110, air can move between the space inside the shoe and the first space 110.

The second valve member 300 includes a first flexible plate 301 having flexibility and being in the form of a flat plate, one side of which is in contact with the lower end of the partition 121 and the other side of which is in contact with the first air passage 131, A second flexible plate 302 having the same size as that of the first flexible plate 301 and overlapped with the first flexible plate 301 and a second flexible plate 302 having a first flexible plate 301 and a second flexible plate 302, And a vent plate (320) interposed between the flexible plates (302) and having a concavo - convex part formed on one side thereof.

The first flexible plate 301 and the second flexible plate 302 are made of a thin synthetic resin film or a material such as silicone or rubber and have flexibility. On the contrary, the air plate 320 is deformed by high- Resistant heat-resistant material.

The edges of the first flexible plate 301 and the second flexible plate 302 are bonded to each other through the bonding portion 310 so that an inlet 311 and an outlet 312 are formed on one side and the other side of the non- .

The ventilation plate 320 is inserted into the inlet 311 side of the partition wall 121 so that the air in the first space 110 can be transferred to the third space 130.

6, the first flexible plate 301 and the second flexible plate 302, to which a part of the first flexible plate 301 and the second flexible plate 302 are attached via the bonding portion 310, are arranged such that the inlet 311 side contacts the end of the partition 121, Can be fused to the middle window 100 by a high frequency in a state where the first air passage 131 is disposed in the first air passage 131.

In this case, since the ventilation plate 320 which is not fused by the high-frequency heat is provided in the inlet 311, the space between the first and second flexible plates 301 and 302 and the space of the first space 110 are interconnected While the first and second flexible plates 301 and 302 on the side of the outlet 312 are in contact with each other.

In this state, when air flows into the space inside the first space 110 and the internal pressure rises, the first and second flexible plates 301 and 302 on the outlet 312 side are opened by the pressure, The air in the first space 110 is moved to the third space 130.

On the other hand, since the outlet 312 of the first and second flexible plates 301 and 302 is not opened even if air flows into the space inside the third space 130 and the internal pressure rises, only one directional air flow .

The partition wall 121 is disposed between the second space 120 and the third space 130 and the first air passage 131 is located between the first space 110 and the second space 120. [ If the inlet 311 of the second valve member 300 is located at the lower end of the partition wall 121 between the second space 120 and the third space 130, 2 valve member 300 will control the air in the third space 130 to be transported only to the first space 110. [

As described above, it will be understood that the second valve member 300 can change the air flow direction depending on the installation direction thereof.

The ventilation member 400 includes a third flexible plate 401 which is flexible and has a flat plate shape, one end of which is connected to the third space 130 and the other end of which is connected to the outside, A fourth flexible plate 402 having the same size as the third flexible plate 401 and overlapped with the third flexible plate 401 and spacers 420 interposed between the third flexible plate 401 and the fourth flexible plate 404 ).

The third flexible plate 401 and the fourth flexible plate 402 are made of a thin synthetic resin film or a material such as silicone or rubber and have flexibility. The spacer 420 is not particularly limited to materials, It is satisfactory if it has a degree of elasticity and flexibility that can be bent and is not easily compressed by an external force.

The edge of the third flexible plate 401 and the edge of the fourth flexible plate 402 are bonded to each other with the bonding portion 410 and the non-bonding portion 411 is bonded to the third space 401 And a passageway interconnecting the outer spaces is formed.

That is, since the external air and the space of the third space 130 are formed by the non-adhesive portion 411, the external air is introduced into the third space 130, .

The spacer 420 is formed of a wire or other material in the form of a wire such that the two wires are parallel to each other in the non-adhesive portion 411, and in the third space space, So that the non-adhering portion 411 can always be kept open by the spacer 420.

Although not shown at the outer end of the ventilation member 400, the outer end of the ventilation member 400 may be attached to the upper of the shoe, and a cover member (not shown) may be formed at the upper portion for concealing the outer end of the ventilation member 400 have.

The first cushioning member 115 and the second cushioning member 135 having elasticity and breathability, such as sponge or foamed urethane, may be inserted into the first space 110 and the third space 130, respectively, The cushioning members 115 and 135 may be formed with assembly regions 116 and 136 which are spaces for assembling the first valve member 200 and the spacer 420 of the ventilation member 400.

The operation of the ventilated midsole 100 constructed as described above will be described.

2 and 6, the space of the first space 110 is compressed when the shoe wearer is walking, and the air inside the space is compressed by the second valve member 300, which enables only one- The air in the shoe internal space is instantaneously sucked into the first space 110 through the hole 215 which has been opened by the deformation of the first valve member 200 at the time of decompression.

When the third space 130 is compressed, the flow into the first space 110 is blocked by the second valve member 300 having the check valve function. Therefore, (400).

The air in the shoe internal space is sequentially passed through the first valve member 200, the first space 110, the second valve member 300, the third space 130, and the ventilation member 400 And is discharged outside.

As described above, if the second valve member 300 is disposed in the opposite direction to the inlet 311 and the outlet 312, the flow of air is reversed, and the outside air flows into the space inside the shoe.

7 is a cross-sectional view of the main part of the integral type half-body including ventilation and comfort according to the second embodiment of the present invention.

7, in order to further reinforce the cushioning property of the integral heel 100 including the breathability and the accommodation according to the second embodiment of the present invention, in the middle space 100, the third space 130 The air space 140 is formed by the upper part of the air space 140 and the upper part of the air space 140 is recessed upward to form the air space 140. At this time, the air space 140 is interposed between the third space 130 and the air space 140, Thereby forming a separate air layer which is shielded from the outside air.

The inner cover 150 may be made of the same material as the middle window 100 and may be fixed to the middle window 100 by adhesive or high frequency heat bonding.

In this case, since the air space 140, which is another air layer, is formed on the third space 130, the cushioning property of the heel portion can be further improved.

Although the present invention has been described in connection with the preferred embodiments described above, it will be appreciated by those skilled in the art that various other modifications and variations can be made without departing from the spirit and scope of the invention, All such changes and modifications are intended to be within the scope of the appended claims.
