Fig. 2 is a perspective view of a shoe check valve plate according to an embodiment of the present invention.

Fig. 3 is a view showing a state of use of the shoe check valve plate of Fig. 2;

A shoe check valve according to a preferred embodiment of the present invention will be described in detail by way of drawings board. Detailed descriptions of well-known functions and configurations that are not clear to the gist of the present invention are omitted.

2 and 3 are a check valve plate for a shoe according to an embodiment of the present invention, FIG. 2 is a perspective view of a check valve plate for a shoe according to an embodiment of the present invention, and FIG. 3 is a use state of a check valve plate for a shoe of FIG. Figure.

Referring to the drawings, a shoe check valve plate 100 according to an embodiment of the present invention includes a porous valve plate 10 and a valve 20.

Referring to FIG. 2, the porous valve plate 10 is bonded and laminated on the upper surface of the sole 1 having the receiving groove 1a for closing the receiving groove 1a. The porous valve plate 10 is made of a material having a predetermined elastic force so as to be Easy to shrink and swell.

Referring to FIG. 3a, for the ventilation of the shoe, the periphery of the sole 1 is formed with a passage portion 5 that communicates with the receiving groove 1a and discharges air inside the shoe to the outside, and the end portion of the channel portion 5 is provided with a general shoe. The check valve 6 and the air flowing from the accommodating groove 1a to the passage portion 5 are discharged to the outside by the check valve, and the check valve prevents outside air from flowing into the passage portion 5.

Referring to FIG. 3a, when the porous valve plate 10 is pressed due to the weight of the wearer during walking, the porous valve plate is expanded (pressed) downward while contracting the internal space of the receiving groove 1a to be in close contact with the sole. Referring to Fig. 3b of the accommodating groove 1a of 1 again, when the pressing of the porous valve plate is released, the porous valve plate 10 is restored and the internal space of the accommodating groove 1a is expanded and restored.

Further, referring to Fig. 2, a deformation preventing groove 40 is further formed around the edge of the porous valve plate 10 and on the upper surface of the porous valve plate 10 formed in the peripheral portion of the valve 20 of the porous valve plate 10.

The deformation preventing groove compensates for the contraction and expansion of the porous valve plate 10 which occurs during the process of bonding and fixing the porous valve plate 10 to the sole 1 and the intermediate pad 7, thereby preventing the porous valve plate 10 from being inflated and pulled in advance. The valve 20 is opened or the function of preventing the porous valve plate 10 from contracting to form the valve 20 of the porous valve plate 10 is smoothly opened.

Referring to FIG. 2, the valve 20 is formed in the interior of the porous valve plate 10 in a plurality of manners, and is selectively opened and closed by air pressure, and the valve is formed in the thickness t of the porous valve plate 10.

That is, the valve 20 is formed in the porous valve plate 10 having a predetermined thickness t, and at this time, the lower portion of the valve 20 does not protrude to the lower portion of the porous valve plate 10, thereby being compared with the one previously developed by the applicant. "Korean Patent No. 10-1164463 (invention name: shoes having air circulation function)" has the thickness T of the porous valve plate 2 of the valve 3, which can greatly reduce the porous valve plate of the present invention having the valve 20. The thickness t of 10, therefore, the shoe check valve plate 100 of the present invention is easily applied to a shoe having a thin sole, which ensures the universal use of the product.

Referring to FIG. 2, the valve 20 is formed in a hemispherical shape having a predetermined elastic force, an open upper end, and an empty interior, and one or more switch portions 21 are formed to be cut at the side of the valve 20.

When the shoe sole is provided with the check valve plate 100 of the present invention which is composed of a porous valve plate and a valve, during the walking, if the porous valve plate 10 is pressed downward, the housing 1 is accommodated as shown in FIG. 3a. The groove 1a is contracted to generate an air pressure inside, and the switch portion 21 of the valve 20 is pressed by the air pressure to be closed. Thereby, the air of the accommodating groove 1a flows through the channel portion 5 to the non-return The valve 6 is discharged to the outside.

On the other hand, referring to FIG. 3b, when the pressing operation of the porous valve plate 10 is released and the porous valve plate 10 is restored, the receiving groove 1a of the sole 1 is expanded, and at this time, the outside air is expanded by the receiving groove 1a. The air suction force generated in the flow flows into the shoe and flows to the upper portion of the valve 20, and the switch portion 21 of the valve 20 flows into the accommodating groove 1a. At this time, the switch portion 21 of the valve 20 is naturally opened by the inflowing air pressure, and the air flows into the inside of the accommodation groove 1a.

Referring to FIG. 2, a first annular tension groove 31 is further provided, and an upper surface of the porous valve plate 10 is formed apart from the outer side of the valve 20; an annular second tension groove 32 is formed in the porous valve plate 10. The lower surface is formed to be spaced apart from the outer side of the first tension groove 31, so as to be formed in a normal zigzag shape.

That is, during the walking process, the porous valve plate 10 is continuously pressed by the weight of the pedestrian, and at this time, the pressed force is transmitted to the valve 20 formed on the porous valve plate 10, when the valve 20 is opened and closed. When the portion 21 is deformed and opened, air cannot be smoothly circulated into the shoe. Referring to Fig. 3a, the force transmitted from the normal zigzag grooves 31 and 32 outside the valve 20 is guided and deformed. Naturally, the force transmitted from the tension grooves 31, 32 is released, so that the valve 20 is not affected by an external force.

Referring to Fig. 2, an annular locking projection 33 inserted into the hole 4a of the inner pad 4 is further formed at a lower portion of the porous valve plate 10 in which the valve 20 is formed.

During the expansion and restoration of the porous valve plate 10, by the locking protrusion The valve 20 is guided to be stably fixed to the hole 4a of the inner pad 4, so that, as shown in FIG. 3a, the outside air flows into the hole 4a of the inner pad 4 through the valve 20, and can be stably transmitted to the sole 1 The tank 1a is accommodated.

On the one hand, the locking projection 33 guides the porous valve plate 10 to be pressed down to contact the sole 1 to support the valve 20 to prevent the switch portion 21 of the valve 20 from being deformed and opened.

Here, in the "Korean Patent Grant No. 10-1164463 (invention name: shoes having an air circulation function)" which was developed by the present applicant, the valve 3 formed to protrude from the lower portion of the porous valve plate 2 is prevented from being worn with the sole. 1 contact, the thickness of the inner pad 4 supporting the porous valve plate 2 is made thicker, but the shoe check valve plate 100 of the present invention is because the valve 20 does not protrude to the lower portion of the porous valve plate 10, so Since it is made thin, the shoe check valve plate 100 of the present invention can be easily applied to a shoe having a thin sole.

The shoe check valve plate 100 of the present invention having the above-described constituent elements forms the valve 20 inside the porous valve plate 10 having a predetermined thickness t, and the valve 20 does not protrude to the lower portion of the porous valve plate 10. According to the present invention, the thickness of the porous valve plate 10 having the valve 20 can be reduced, and the structure (technique) of the shoe check valve plate 100 of the present invention can be easily applied to shoes having a thin sole. In this way, the use of the product can be ensured universally.

By the structure in which the valve 20 is not exposed to the lower portion of the porous valve plate 10, even if the thickness of the inner pad 4 of the elastic supporting porous valve plate 10 is made thin, the valve can be stably prevented from being pressed by the porous valve plate 10. 20 Touching the sole 1 causes the switch portion 21 of the valve 20 to be opened, so that it can be applied to a shoe having a thin sole, which ensures the universal use of the product.

Further, the tension grooves 31, 32 absorb and cancel the external force transmitted to the valve 20 by the zigzag pattern, so that even if the porous valve plate 10 is deformed by an external force, the valve 20 formed on the porous valve plate 10 does not. The valve 20 is deformed due to an external force, and the valve 20 can stably perform the switching function.

The shoe check valve plate 100 of the embodiment of the present invention having the above configuration is provided to the sole 1 to continuously circulate air.

First, as shown in FIG. 3a, when the pedestrian's weight-bearing porous valve plate 10 is pushed down and expanded during walking, the internal space of the receiving groove 1a of the sole 1 is contracted to generate air pressure inside. The switch portion 21 of the valve 20 is closed by the air pressure pressing, whereby the air of the accommodation groove 1a flows into the check valve 6 via the passage portion 5 and is discharged to the outside.

Then, referring to FIG. 3b, when the pressing of the switch portion is released and the porous valve plate 10 is restored, the internal space of the housing groove 1a of the sole 1 is expanded, and the internal space of the receiving groove 1a is expanded. The air is attractive, and the outside air flows into the shoe and flows into the upper portion of the valve 20, and flows into the accommodating groove 1a through the switch portion 21 of the valve 20. At this time, the opening portion 21 of the valve 20 is naturally opened by the inflowing air pressure, whereby the air flows into the inside of the accommodation groove 1a.

Thereby, during the walking, the porous valve plate 10 continuously discharges and recovers the load of the pedestrian while discharging the air in the shoe to the outside, and again flows the air corresponding to the discharge amount into the shoe from the outside, thereby Smooth ventilation inside the shoe.

However, the above description is only a preferred embodiment of the present invention, and the application of the present invention can be used. It is obvious to those skilled in the art that various modifications and changes can be made without departing from the spirit and scope of the invention. The equivalent structural changes in the specification and the drawings are included in the scope of the present invention and are combined with Chen Ming.
