Description

  The present invention relates to a ventilation shoe.

  Since shoes have poor breathability inside the shoes, if they are worn for a long time, their feet will become stuffy, causing the wearer to feel uncomfortable as well as causing athlete's foot. Therefore, a pump chamber is provided on the sole, and the pump chamber is compressed using the weight fluctuation of the wearer applied to the shoe when walking and the load variation due to bending, and the air is exhausted to the toe tip to ventilate the inside of the shoe. Ventilated shoes that are designed to do so are provided.

  As such a configuration, the pump chamber is provided on the thick heel side, the opening of the intake passage communicating with the outside air is disposed at a position located on the heel of the wearer's foot, and the opening of the exhaust passage is positioned around the fingertip The intake passage and the exhaust passage are communicated with the pump chamber via check valves, respectively, and the pump chamber is compressed by stepping on the ventilation shoes, so that the indoor air is drawn from the exhaust passage to the foot. The inside of the shoe is ventilated by the action of discharging around the fingertips, restoring the pump chamber by lifting the shoe, and sucking air from the intake passage to the pump chamber by the negative pressure.

Japanese Patent Application Laid-Open No. 2014-230347

  In the conventional configuration, the ventilation shoe requires a check valve that allows air to flow in and out only in one direction between the pump chamber and the intake passage and between the pump portion and the exhaust passage. However, since the check valve has a structure in which a commonly used ball valve or the like is used in the heel, the structure becomes complicated and excessively heavy.

  In addition, the check valve is applied to a place where bending, heavy load, and wear constantly occur, and a strict thickness reduction is required. Therefore, a check valve that can withstand this is not proposed. A configuration using a reed valve as a check valve (Japanese Patent Application Laid-Open No. 2004-181113) is also disclosed, but all of them are conceptual areas on a desk and are not embodied.

  Furthermore, in the conventional configuration such as the prior art document, the pump chamber provided in the heel portion and the check valve are communicated with each other through a pipe, and the height dimension of the pump chamber is increased. It is necessary to do so, and the sole of the ventilation shoe becomes thick. In addition, check valves, pipes, and the like have many joint portions to be sealed, and are easily peeled off and broken. Furthermore, since the pipe extends in the sole, there is a problem that when the wearer walks, the sole is prevented from being bent and the pump chamber cannot be sufficiently compressed.

  As described above, since an optimum valve structure has not been developed particularly as a check valve for a ventilation shoe, various types of ventilation shoes have been proposed on the desk, but the actual situation is that they are not actually on the market. .

  SUMMARY OF THE INVENTION An object of the present invention is to provide a ventilated shoe that solves the conventional problems and can sufficiently ventilate the inside of the shoe and is suitable for practical use.

The present invention
An upper, a sole, and a ventilation device for ventilating the air inside the shoe,
The ventilator is
An intake passage communicating with outside air;
An exhaust passage that opens to the sole surface near the toe position and exhausts air into the shoe;
An intake check valve disposed in communication with the intake passage and an exhaust check valve disposed in communication with the exhaust passage;
It is provided in the sole and compressed as it is depressed, and the air stored inside is sent from the exhaust passage through the exhaust check valve into the shoe interior, restored as the pedal is released, and the intake check valve is And a pump chamber that takes in air from the intake passage through
The intake check valve and the exhaust check valve are:
A support member having a main surface portion formed with an opening and closing hole;
A valve body made of a thin material having flexibility, having one end held by a supporting member, covering the opening / closing hole from the inside, and deforming inward by applying air pressure to the opening / closing hole from the outside, thereby opening the opening / closing hole And
The sole is formed by laminating a plurality of bottom plates,
The pump chamber consists of a flat chamber formed between the bottom plates,
Inside the sole, a valve mounting hole for accommodating each check valve is formed, and each check valve is fitted into the valve mounting hole so that the opening / closing hole is positioned in the vertical direction,
In the intake check valve, the outside of the opening / closing hole is communicated with the intake passage ventilated with the inside of the shoe, and the inside of the opening / closing hole is arranged in communication with the pump chamber,
The exhaust check valve is a ventilation shoe characterized in that the outside of the opening / closing hole is in communication with the pump chamber and the inside of the opening / closing hole is in communication with the exhaust passage.
Here, the inside of the opening / closing hole refers to the side where the valve element is held, and the outside of the opening / closing hole refers to the side where the valve element is not held.

  In such a configuration, when the pump chamber is compressed with walking, the valve body acts from the opening / closing hole of the exhaust check valve, the opening / closing hole is opened, and air flows into the valve space. . Then, air is released around the toes through the exhaust passage. When the curvature of the pump chamber is released by releasing the depression of the shoe, the pump chamber is restored to a flat plate shape, whereby the volume increases and the pump chamber becomes negative pressure. As a result, the inside of the valve space of the intake check valve becomes negative pressure, acts on the opening / closing hole through the intake passage, the valve body is opened, and the outside air flows into the pump chamber through the shoe body. To do. Thereby, ventilation in a shoe main part will be made continuously.

  In the above-described configuration, the check valve is integrally formed of a supporting member having a main surface portion in which an opening / closing hole is formed and a valve body having one end held by the supporting member and opening the opening / closing hole. It can be easily assembled by mounting it in the sole and communicating with the intake passage or the exhaust passage.

Here, the intake check valve and the exhaust check valve constitute the carrying member, and include a main surface portion and a side surface portion continuous to the main surface portion, It can be configured as a valve space, and includes a flat open case in which an opening / closing hole is formed in the main surface portion, and a valve body that holds one end in the opening case and covers the opening / closing hole from the inside. .
In such a configuration, since the valve space is defined by the side surface portion around the open case, the external shape of the open case is made to coincide with the valve mounting hole, so that the valve mounting hole is stably held.

The check valve for intake and the check valve for exhaust include the flat open case, a valve body that covers the opening / closing hole from the inside, and a cover that covers the open surface of the open case, The cover divides the valve space, and a communication hole is formed in the cover. In the intake check valve, the opening / closing hole is connected to the intake passage, and the communication hole is connected to the pump chamber. In the exhaust check valve, the open / close hole can be communicated with the pump chamber, and the communication hole can be communicated with the exhaust passage.
In such a configuration, the valve space is surrounded by an open case and a cover, and it is an integrated configuration that is unitized and easy to handle, and can be easily installed by mounting it in the valve mounting hole formed in the bottom plate. In addition, the ventilator can be configured, and the open case and the cover have the advantage that the valve body is reliably protected from the impact caused by walking and has excellent durability.

  In the above-described configuration, the valve body can be held by sandwiching one end of the valve body between the open case and the side surface portion of the cover, whereby the valve body is easily fixed by mutual assembly. The Further, a folding margin formed by bending one end of the valve body at a right angle may be provided, and one end of the valve body may be held by sandwiching the folding margin between the side surface portion of the open case and the side surface portion of the cover. The valve body is securely fixed by this folding allowance.

  The check valve suitable for the ventilation shoe of the present invention is extremely thin with a thickness of several millimeters and requires high impact resistance, but with such a configuration, the check valve is easy to manufacture, small in size, robust, and A non-return valve for a ventilated shoe having a stable body and stable performance can be realized, and a feasible provision of a ventilated shoe that has been a product on a conventional desk is possible.

In addition, a valve mounting hole for accommodating an intake check valve and a valve mounting hole for accommodating an exhaust check valve are installed at any one of the intermediate bottom plates, where other bottom plates overlap vertically. The exhaust check valve is inserted into the valve mounting hole so that the outside of the opening / closing hole is positioned upward, and the outside of the opening / closing hole is positioned downward, so that the intake check valve is positioned between the bottom plates. Also proposed is a configuration in which the pump chamber formed in is connected from the inside to the open / close hole of the intake check valve via the common passage leading to the lower part of the check valve, and from the outside to the open / close hole of the exhaust check valve Is done.
In such a configuration, the two check valves are arranged adjacent to each other at the heel position on the heel, which is the strongest of the shoes and hardly receives the deformation force. For this reason, damage of both check valves is suppressed, and the durability of the ventilation shoe itself is improved.

Further, the sole is formed by laminating a plurality of bottom plates, the pump chamber is a flat chamber formed between the bottom plates, and an intermediate bottom plate in which the other bottom plates overlap with each other is almost equal to the thickness of the check valve. Equally, a valve mounting hole for accommodating the check valve is formed, and each check valve is fitted in the valve mounting hole. A configuration is proposed in which the communication hole communicates with the pump chamber, and the exhaust check valve has an open / close hole communicated with the pump chamber and the communication hole communicated with the exhaust passage.
In such a configuration, a valve mounting hole is formed in one of the intermediate bottom plates, and a check valve is mounted here, and the ventilation device can be easily configured by stacking the bottom plates.

  Here, the ventilation shoes include all shoes requiring ventilation, such as men's shoes, women's shoes, sports shoes, safety shoes, boots, boots, and golf shoes.

  The sole is configured by laminating a plurality of bottom plates, the pump chamber is formed in a flat shape between the bottom plates, a valve mounting hole is formed in an intermediate bottom plate where other bottom plates overlap each other, and the valve mounting hole Since the check valve integrated through the support member is mounted, the thickness of the sole can be reduced, the ventilation shoes can be downsized, and the volume of the pump chamber can be increased. The ventilation in the shoe body can be performed sufficiently.

  In addition, the ventilation shoe 30 includes a ventilation device that takes in outside air via the shoe interior 34 and releases it to the toe side of the shoe interior 34. This ventilation device will be described.

  The ventilation device is formed to be opened at the rear end portion of the shoe interior 34, and is formed to be opened on the sole surface near the toe position of the shoe interior 34, the intake passage L1 for inhaling the air inside the shoe interior 34, An exhaust passage L2 for exhausting air into the shoe interior 34 and a pump chamber P for sending air sucked in the intake passage L1 to the exhaust passage L2 are provided.

  The intake passage L1 has a plurality of openings 148a to 148c formed in the width direction of the ventilation shoe 30 at the rear end portion of the insole plate 35, and the rear end of the midsole plate 36 in the present embodiment. In the present embodiment, a plurality of intake passages 151a to 151c are formed in communication with the openings 148a to 148c and the pump chamber P. The openings 148a to 148c and the intake passages 151a to 151c communicate with an intake check valve V1 disposed immediately below to constitute an intake passage L1 to perform intake.

  The exhaust passage L2 has a plurality of openings 149a to 149d formed in the width direction of the ventilation shoe 30 at the front end portion of the insole plate 35 and, in the present embodiment, the width at the front end portion of the midsole plate 36. In the present embodiment, a plurality of exhaust passages 155a to 155d and exhaust guide passages 156 formed at the front end of the lower bottom plate 37 are provided, and openings 149a to 149d and exhaust passages 155a to 155a are formed in the direction. 155d performs exhaust by communicating with an exhaust guide path 156 formed immediately below and an exhaust check valve V2 to form an exhaust path L2.

  In this way, the ventilator has the pump chamber P formed by forming a space between the bottom plate 37 and the main plate 38, which are intermediate bottom plates, and intake passages 151a to 151c at the rear end of the bottom plate 37. An intake valve mounting hole 152 formed in communication, an intake check valve V1 accommodated in the valve mounting hole 152, and an exhaust valve formed in communication with the exhaust guide path 156 at the front end of the lower bottom plate 37 A mounting hole 157 and an exhaust check valve V2 accommodated in the valve mounting hole 157 are provided.

  As shown in FIG. 7, the pump chamber P is formed with a recess having a sufficiently wide area with a depth of several millimeters on the upper surface of the bottom plate 38, leaving a peripheral edge at the periphery. 38 is formed by adhering the lower bottom plate 37 to and in close contact with each other, and has a communication port 163 communicating with the intake valve mounting hole 152 at the rear end and a communication port 164 communicating with the exhaust valve mounting hole 157 at the front end. Projecting spacers 38 a and 38 b having an upper surface having the same height as the upper surface of the main bottom plate 38 are formed on the main bottom plate 38. Further, in the pump chamber P, a region 161a between the communication port 163 and the projecting spacer 38a and a region 161b between the projecting spacers 38a and 38b in the pump chamber P are provided with a cushion material 38c made of an elastic material such as rubber. , 38d are disposed between the main bottom plate 38 and the lower bottom plate 37 so as to adhere to each other. Due to the protruding spacers 38a and 38b and the cushioning materials 38c and 38d, changes in the shape of the lower bottom plate 37 due to long-term use of the ventilation shoe 30 are prevented.

  The volume of the pump chamber P can be increased by changing the area, depth, etc. of the recess. In this case, it is possible to further increase the amount of air that can be exhausted into the shoe interior 34 or sucked from outside the shoe interior 34.

Next, a first embodiment of the intake check valve V1 and the exhaust check valve V2 will be described.
As shown in FIGS. 8 to 12, a valve body T, an open case 201, and a cover 202 fitted in the open case 201 without a gap are provided. The open case 201 constitutes the carrying member of the present invention. The intake check valve V1 and the exhaust check valve V2 have the same structure and are arranged upside down.

  The open case 201 includes a main surface portion f and a side surface portion w continuous with the main surface portion f, and has a thin and flat box shape with one surface open. Opening / closing holes 205a and 205b are formed as inlets. Similarly, the cover 202 includes a main surface portion and a side surface portion continuous to the main surface portion, and has a thin and flat box shape with one surface open. The main surface portions have communication holes 206a and 206b as air outlets. Is formed. The opening / closing holes 205a and 205b and the communication holes 206a and 206b are formed eccentric to each other so that the valve body T can smoothly flow air without closing the communication holes 206a and 206b when the opening / closing holes 205a and 205b are opened. Can do. The inside of the open case 201 is installed so that the outside angle of the valve body T is aligned, the cover 202 is inserted into the open case 201, the edge of the valve body T is sandwiched and fixed, and the inside (inside the opening and closing holes 205a and 205b) ) Is formed with a check valve. The open case 201 and the cover 202 are integrated by bonding or caulking.

  As shown in FIG. 8, the valve body T is made of a thin metal plate or synthetic resin plate having a thickness of about 0.03 mm, and its rear end is bent and includes a bending allowance 200. By holding the bending allowance 200 between the case side surface and the cover side surface, the holding of the valve body T is ensured, and the valve body T can be easily assembled to the open case 201 without applying the fixing means of the valve body T. Can do.

  As shown in FIG. 11, the intake check valve V1 is mounted in the intake valve mounting hole 152 with the opening / closing hole 205a upward and the communication hole 206a downward, and the outside of the opening / closing hole 205a is connected to the intake passage L1 ( 1) and the communication hole 206a communicate with the pump chamber P (FIG. 8).

  In addition, as shown in FIG. 12, the exhaust check valve V2 has the opening / closing hole 205b downward, the communication hole 206b upward, the opening / closing hole 205b between the pump chamber P (FIG. 7) and the outside of the communication hole 206b. It communicates with the exhaust passage L2.

  In the intake check valve V1 and the exhaust check valve V2, the open case 201 and the cover 202 are made of a high-strength material such as metal or synthetic resin, and the valve element T is flexible such as metal or synthetic resin. It is made of a thin material having

  The intake check valve V1 is opened when the pressure in the pump chamber P becomes lower than the pressure in the shoe interior 34 (negative pressure), and the air in the shoe chamber 34 is sucked into the pump chamber P from the intake passage L1 and exhausted. The check valve V2 is opened when the pressure in the pump chamber P becomes higher than the pressure in the shoe interior 34, and the air in the pump chamber P is exhausted from the exhaust passage L2.

In the configuration of the check valves V1 and V2 having such a configuration, the valve space is surrounded by an open case 201 and a cover 202, the valve body T is fixed to the open case 201, and is integrated. The unit is easy to handle, and the ventilation device can be easily configured by mounting it in the valve mounting hole formed in the bottom plate. The open case 201 and the cover 202 allow the valve element T to accompany walking. There is an advantage that it is reliably protected from impact and has excellent durability.
Moreover, since the height of the check valves V1, V2 can be set to 2 to 3 [mm], the occupied space can be reduced.

  Here, since the opening / closing holes 205a and 205b and the communication holes 206a and 206b are formed eccentric to each other, the valve body T does not block the communication holes 206a and 206b when the opening / closing holes 205a and 205b are opened. The air can flow smoothly. Furthermore, since the intake check valve V1 and the exhaust check valve V2 have the same structure, they can be used by selecting the front and back of the check valve.

Next, the ventilation structure of the shoe interior 34 will be described.
In the ventilation shoe 30, air outside the shoe interior 34 is sucked into the shoe interior 34, circulated, and exhausted outside the shoe interior 34 by the ventilation device. However, if the foot of the wearer is in close contact with the inner circumferential surface of the upper 31 and the surface of the insole board 35 when the ventilation shoe 30 is worn, the air permeability of the shoe interior 34 is deteriorated. As a result, the air outside the shoe interior 34 cannot be taken into the shoe interior 34, the air is circulated within the shoe interior 34, and the air inside the shoe interior 34 cannot be exhausted sufficiently outside the shoe interior 34.

  Therefore, in the present embodiment, as shown in FIG. 2 and FIG. 13, the back surface between the wear mouth portion 31 a and the toe portion 31 b of the upper 31, the back surfaces of the collar portion 31 c and the side portion 31 d, and the insole plate 35 On the surface, a sheet 80 having a concavo-convex groove array is adhered, and an air passage 41 communicating with the outside air in the shoe interior 34 is formed. As a result, the outside of the shoe interior 34 is communicated with the air passage 41 so that air can be sufficiently circulated in the shoe interior 34 and the air inside the shoe interior 34 can be sufficiently discharged to the outside of the shoe interior 34. Or the air outside the shoe interior 34 can be sufficiently taken into the shoe interior 34.

  As a result, the inside and outside of the shoe 34 are communicated with each other via the first to third air passages 41 to 43 (see FIG. 1), so that air can be sufficiently circulated within the shoe inside 34 and the shoe. The air inside the interior 34 can be exhausted to the outside of the shoe interior 34, and the air outside the shoe interior 34 can be sufficiently taken into the interior of the shoe 34.

  In the present embodiment, the sheet 80 having the concavo-convex groove row is formed, for example, by applying a stepped process to the leather at a predetermined pitch and applying a synthetic resin to the back side thereof.

  In this way, the intake passage L1 communicates with the outside air via the shoe interior 34, and unlike the conventional configuration in which an opening is formed in the heel 33 or the like, rainwater or the like does not enter from the opening, It will be suitable for practical use.

Next, the operation of the ventilation shoe 30 will be described.
Wearing ventilation shoes 30 and stepping on one foot adds weight to the other landing foot, raising the heel and standing on the toes, and accordingly, the sole 32 is compressed and curved, In the pump chamber P, the lower bottom plate 37 and the main bottom plate 38 approach, the pump chamber P is compressed, and the pressure increases. As a result, air pressure is applied to the valve body T from the opening / closing hole 205b of the exhaust check valve V2, and the valve body T opens inward as shown by a chain line in FIG. 12, and the opening / closing hole 205b opens to open the exhaust check valve V2. The air in the chamber P is discharged into the exhaust passage L2, and is exhausted into the shoe interior 34 through the openings 149a to 149d. At this time, the intake check valve V1 is closed.

  Next, when one stepped foot is landed and the other foot is stepped on, the ventilation shoe 30 of the other foot leaves the ground and the sole 32 returns to a flat state, the pump chamber P is decompressed, and the lower bottom plate 37 and the main bottom plate 38 are separated from each other, and the pump chamber P is restored to a negative pressure. As a result, the valve body T of the intake check valve V1 opens inward as shown by a chain line in FIG. 11, the intake check valve V1 is opened, and the air inside the shoe 34 opens in the direction of the arrow in FIG. The air is taken in from 148c and sent to the pump chamber P via the intake passage L1 and the intake check valve V1. Accordingly, air outside the shoe interior 34 is sucked into the shoe interior 34. At this time, the exhaust check valve V2 is closed.

  In this way, when the wearer steps and walks alternately, the air sucked into the pump chamber P from the intake passage L1 is exhausted from the exhaust passage L2 into the shoe interior 34, and the ventilation inside the shoe interior 34 continues. Done.

  In the present embodiment, air outside the shoe interior 34 is sucked into the shoe interior 34 from the upper edge of the upper 31, and is discharged out of the shoe interior 34 from the upper edge of the upper 31. In order to take in, it is not necessary to form an air intake hole, an air discharge hole, or the like in the upper 31, the sole 32, or the like of the ventilation shoe 30. Therefore, rainwater or the like does not enter the shoe interior 34 as the shoe interior 34 is ventilated.

  Further, since the protruding spacers 38a and 38b are formed to extend in the width direction of the ventilation shoe 30, the curvature of the insole board 35, the midsole board 36, the lower bottom board 37, and the main bottom board 38 when the wearer walks. Is not blocked by the protruding spacers 38a and 38b. Therefore, the volume of the pump chamber P can be changed sufficiently.

  Further, since the cushion members 38c and 38d are disposed in the pump chamber P, the weight is applied by walking and the sole 32 is compressed and curved, and the lower base plate 37 and the main base plate 38 are brought close to each other in the pump chamber P. Then, when the sole 32 returns to a flat state, the lower bottom plate 37 and the main bottom plate 38 can be quickly restored and separated in the pump chamber P. Therefore, the shoe interior 34 can be reliably ventilated.

  Further, in the present embodiment, as shown in FIG. 1, the intake check valve V1 is disposed behind the heel Ar11, and the exhaust check valve V2 is disposed forward of the toe tip Ar12. During walking, the intake check valve V1 and the exhaust check valve V2 are not damaged by being loaded. Therefore, the durability of the ventilation shoe 30 can be improved. Further, since the intake check valve V1 and the exhaust check valve V2 do not hit the foot, the wearer does not feel uncomfortable.

  Next, a second embodiment of the present invention will be described. In addition, about the thing which has the same structure as 1st Embodiment, the same code | symbol is provided and the effect of the same embodiment is used about the effect of the invention by having the same structure.

In the present embodiment, the sole 32 is an insole plate 235 serving as a second bottom plate that contacts the back surface of the foot, and a first bottom plate disposed so as to overlap the insole plate 235 below the insole plate 235. A bottom plate 236, a lower bottom plate 237 disposed so as to overlap with the middle bottom plate 236 below the middle bottom plate 236, and a main bottom plate 238 disposed so as to overlap with the lower bottom plate 237 below the lower bottom plate 237.

  The pump chamber P is formed between the insole plate 235 and the midsole plate 236, and the communication hole 206 a of the intake check valve V <b> 1 is passed through the first to third intake guide paths 253, 254, and 255. The open / close hole 205b of the exhaust check valve V2 communicates with the pump chamber P via the first to third exhaust guide paths 256, 257, and 258.

  The pump chamber P is formed by deforming the insole plate 235 and forming a space having a sufficiently wide area with a depth of several millimeters between the pump chamber P and the pump chamber P. Inside, cushion materials 238c and 238d made of an elastic material such as foam rubber are disposed between the insole plate 235 and the insole plate 236.

A first lower bottom plate 560, a second lower bottom plate 570 disposed below the first lower bottom plate 560, and a main bottom plate 580 disposed below the second lower bottom plate 570. The pump chamber P is formed by covering the opening 571 of the second lower bottom plate 570 with the first lower base plate 560 and the main bottom plate 580 on the upper and lower sides thereof. The heel 33 is fixed to the heel of the bottom plate 580 from below. The first lower bottom plate 560, the second lower bottom plate 570, and the main bottom plate 580 constitute a bottom plate that forms the sole 32 by being laminated.

Each structure of a baseplate is demonstrated according to FIGS.
The insole board 530 shown in FIG. 19 has a plurality of openings 531 serving as exhaust ports at the front portion corresponding to the finger position. In addition, four openings 532 serving as intake ports are formed in the rear part.

  The board plate 540 that is overlapped with the insole plate 530 is joined on the folded portion 550 to form the upper 31, and as shown in FIG. 18, the opening 541 that matches the opening 531 and the opening that matches the opening 532 and the opening that matches the opening 532 below. 542.

  As shown in FIG. 18, communication openings 551 a and 551 b are formed in the folded portion 550 depending on the thickness of the folded portion 550. The communication openings 551a and 551b are blocked by a blocking film portion 552 having the same thickness as the folded portion 550 formed in the vicinity of the eaves, and communicate with the communication hole 206b of the exhaust check valve V2 on the eaves side of the communication opening 551a. Thus, it extends forward and faces the openings 531 and 541 from below. As shown in FIG. 20, a thin plate-like spacer 555 having the same thickness as the folded portion 550 is disposed in the communication opening 551a.

  The periphery of the spacer 555 becomes a communication path 553 (see FIGS. 18 and 20), and communicates with the openings 531 and 541 in the front via the communication path 553. Further, the communication opening 551b communicates with the opening / closing hole 205 of the intake check valve V1 from above at the rear. The spacer 555 has a shape that does not block the openings 531 and 541 at the front, and extends to the openings 531 and 541. By the spacer 555, the height of the communication path 553 is held without being compressed.

  An exhaust communication hole 561 is formed in the front portion of the flange portion of the first lower bottom plate 560 shown in FIG. 21, and an intake communication hole 562 is formed in the rear thereof. The exhaust communication hole 561 coincides with the communication hole 206b of the exhaust check valve V2, and the intake communication hole 562 coincides with the opening / closing hole 205a of the intake check valve V1.

  As shown in FIG. 22, the second lower bottom plate 570, which is an intermediate bottom plate, has an opening 571 that is hung forward from the arch portion and becomes the pump chamber P. Further, the exhaust check valve is disposed on the front side of the heel portion. A rectangular valve mounting hole 572 in which V2 is closely mounted is formed on the rear side, and a rectangular valve mounting hole 573 in which the intake check valve V1 is closely mounted is formed on the rear side. The thickness of the second lower bottom plate 570 is the same as the thickness of the check valves V1 and V2, and is set to about 2 to 4 mm.

  A common path 581 is formed on the upper surface of the rear half of the bottom plate 580 shown in FIGS. This common path 581 is formed of an elongated groove that reaches the opening 571 of the second lower bottom plate 570 at the front end portion and crosses the valve mounting holes 572 and 573 downward at the rear portion. Also, two cushion materials 582 are bonded to the upper surface of the front half. The cushion material 582 is disposed so as to be accommodated in the opening 571 in a laminated state, and the thickness thereof is substantially equal to the thickness of the second lower bottom plate 570. With this configuration, the first lower bottom plate 560 is covered on the opening 571, and the lower surface side of the opening 571 is covered with the main plate 580, whereby the pump chamber P whose upper and lower surfaces are shielded by the opening 571 is configured. The cushioning material 582 helps restore the compressed pump chamber.

  The lower bottom plates 560 and 570 and the main bottom plate 580 are made of an elastic material such as rubber or soft synthetic resin, and are bonded to each other by an adhesive or the like, and both function as a bottom plate to form the sole 32.

Next, a sixth embodiment of the present invention will be described.
In the above-described embodiment, the spacer 555, the first lower bottom plate 560, and the second lower bottom plate 570 are formed and joined on the front and back sides, but it is also possible to integrally form them.
25 and 26 show such a configuration, and components having the same significance as those described above are denoted by the same reference numerals and description thereof is omitted.
A groove-shaped opening 571, an exhaust valve mounting hole 572, and an intake valve mounting hole 573 are formed on the lower surface of the lower bottom plate 600, which is an intermediate bottom plate, and an exhaust communication hole is provided immediately above the valve mounting holes 572 and 573. 561 and an intake communication hole 562 are formed. A protruding spacer 555 is integrally formed on the upper surface of the lower bottom plate 600. The bottom plate 580 is disposed on the lower surface of the lower bottom plate 600, and the space of the opening 571 becomes the pump chamber P. Thus, since the spacer 555, the first lower bottom plate 560, and the second lower bottom plate 570 are integrated, the number of laminated bottom plates constituting the sole is reduced, and the structure is simplified.

Next, the ventilation effect of the fifth and sixth embodiments will be described.
When the weight is applied to the pump chamber P formed by shielding the opening 571 by walking and curved, the pump chamber P is compressed, the compressed air passes through the common path 581, and the opening / closing hole 205 b of the exhaust check valve V <b> 2. The valve body T is pushed up to open, and flows out from the communication hole 206b. The air then passes through the exhaust passage L2 including the exhaust communication hole 561, the communication opening 551a, and the openings 531 and 541, and is injected from the opening 531 onto the lower surface of the toe.

  Next, when the shoe leaves the ground and the compression of the pump chamber P is released, the pump chamber P is restored to a flat plate shape, the volume increases, and the inside of the pump chamber P becomes negative pressure. As a result, the pressure in the valve space becomes negative via the common path 581 and the communication hole 206a of the intake check valve V1, and the valve body T is pulled down and opened, and the intake communication hole 562, the communication opening 551b, and the opening 532 are opened. Through the intake passage L <b> 1 composed of 542, the dry air in the soot portion flows into the pump chamber P.

  The dried air is jetted to the lower surface of the toe tip in the shoe interior 34 by compression of the pump chamber P accompanying the next walking. As a result, the shoe interior 34 is continuously ventilated. The action between the toes is the same as that described in the first embodiment, and a description thereof is omitted.

  In the fifth and sixth embodiments, the check valves V1 and V2 are arranged adjacent to each other at the heel position on the heel 33, which is the strongest of the shoes and hardly receives the deformation force. For this reason, breakage of the check valves V1, V2 is suppressed, and the durability of the ventilation shoes themselves is improved.

  The exhaust check valve V2 is disposed on an arch, for example, between the projecting spacer 38a and the cushion material 38c in FIG. 7, or between the projecting spacer 38a and the cushion material 38d, or the exhaust passage L2. It can also be arranged immediately below. In that case, since no load is applied to the exhaust check valve V2 during walking, the exhaust check valve V2 is not damaged.

Next, a second embodiment of the check valves V1, V2 of the present invention will be described.

In the intake check valve V1, the outside of the opening / closing hole 305a communicates with the intake passage L1 (FIG. 1) and the lower part of the valve space (inside the opening / closing hole 305a) communicates with the pump chamber P.

  Further, in the exhaust check valve V2, as shown in FIG. 29, the exhaust case mounting hole 157 is fitted into the exhaust valve mounting hole 157 with the open surface of the open case 301 facing upward, so that A valve space is formed. In the exhaust check valve V2, the outside of the opening / closing hole 305b communicates with the pump chamber P, and the upper part of the valve space (inside the opening / closing hole 305b) communicates with the exhaust passage L2.

  In the present embodiment, since the intake check valve V1 and the exhaust check valve V2 have the same structure, they can be used by turning them upside down. In such a configuration, the valve body T is fixed to the open case 301 and integrated, and the ventilation device can be easily configured by mounting in the valve mounting holes 572 and 573 formed in the bottom plate. In addition, since the valve space is defined by the side surface portion w around the open case 301, by matching the outer shape of the open case 301 with the valve mounting holes 572 and 573, the valve mounting holes 572 and 573 can be stably formed.
