Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to footwear that allows complete ventilation of internal air.

Conventionally, shoes that completely ventilate the air inside the footwear include those that have an air chamber formed by hollow protrusions on the outer sole, or those that provide flexibility to the entire outer sole and form an air chamber inside the outer sole. These shoes circulate the air by compressing the air chamber under the weight of the pedestrian and letting the compressed air flow into the footwear through the midsole.

However, with conventional footwear such as the one described above, sufficient ventilation occurs in the rear part of the footwear through the gap between the pedestrian's ankle and the footwear, but sufficient ventilation is difficult to occur in the front part of the footwear. As a result, there is a drawback in that moist air stagnates around the front periphery, making the feet stuffy.

The present invention was proposed to solve these problems, and its purpose is to provide sufficient ventilation around the front edge of footwear, and to create a footwear metal that is particularly useful for foot health. The purpose is to provide

EMBODIMENT OF THE INVENTION Hereinafter, the structure of this invention will be described in detail based on the drawing which shows an Example.

1 to 4 showing an embodiment of the footwear according to the present invention, reference numeral 1 is the footwear, and 2 is the outer sole thereof.

A standing portion 3 of a predetermined height is formed on the outer sole 2 at its periphery, and a flange portion 4 is further formed on the upper portion of the standing portion 3.

2' is the heel portion of the outer sole 2.

The material of the outer sole 2 is made of an elastic material such as vinyl chloride, synthetic rubber, or urethane.

Reference numeral 5 denotes a pump housed and fixed in front of a recess formed inside the upright portion 3 of the outer sole 2, and its shape is U-shaped to match the shape of the front part of the outer sole 2, and the periphery of the recess In order to achieve this desired sound, it is also possible to provide two approximately linear pumps in addition to the U-shape.

) A cylindrical air chamber 6 is formed in the outer peripheral portion (second
Fig. 3).

A hole 7 is provided throughout the upper part of the air chamber 6, and an exhaust hole 8 is provided at the rear end (FIG. 3).

The pump 5 is made of the same material as the outer sole 2.

Reference numeral 9 denotes a ventilation pipe connected to the exhaust hole 8 of the pump 5, and extends to the vicinity of the bank tread portion 2' of the outer sole 2.

Note that, due to the structure of the human foot, the most space between the shoe and the foot inside the shoe is near the bank tread 2'.

Therefore, it would be more effective if part of the upper skin 10 of the embankment tread 2' is made into a mesh M to exchange air with the outside world.

Reference number 10 is the upper, and its hanging allowance is the outer sole 2.
It is adhesively fixed to the upper surface of the flange portion 4 of.

Reference numeral 11 denotes an insole, which is fixed at the flange portion 40 onto the hanging allowance of the upper 10.

Reference numeral 12 denotes a ventilation hole provided over the entire upper part of the midsole 11.

Note that this vent hole 12 is not provided in a portion of the pump 5 located above the air chamber 6.

14 is a support disposed between the outer sole 2 and the inner sole 110, and is made of an elastic material (FIG. 1).

Figure 4).

In addition, for the above configuration, the height of the pump 5 accommodated in the recess of the outer sole 2 is set to such a height that a slight gap 13 is formed between the upper surface of the air chamber 6 and the inner sole 11. (Figure 1).

Here, the operation of the footwear according to the present invention constructed as above will be explained.

When the load of a pedestrian wearing all footwear 1 is applied, the insole 1
1 presses the pump 5.

At this time, the midsole 11 presses and crushes the pump 5 while blocking the hole 7 of the pump 5, so that the air in the air chamber 6 is pushed out backward through the exhaust hole 8 and the ventilation pipe 9.

Furthermore, at this time, the partial insole 11 of the support body 14 is crushed and the space between the outer sole 2 and the insole 11 is contracted, so that
The air accumulated in the space and the air pushed out through the ventilation pipe 9 are released to the outside from the gap around the pedestrian's ankles through the ventilation hole 12 in the midsole 11.

Furthermore, air is discharged to the outside only by compression of the pump 5.

Next, when the pedestrian's load is removed by one foot of footwear, the pump 5 is restored to its original state.
The surrounding air (stale air) is absorbed into the air chamber 6, and the restoring force of the support body 14 causes the outer sole 2 and the inner sole 1 to
The space between 10 and 10 is restored, and as a result, outside air (fresh air) is sent into the footwear 1 and the space 1 through the gap around the ankle.

As a result, old air and fresh air are circulated.

Since the gap 13 is formed between the upper surface of the air chamber 6 and the inner sole 11, absorption by the pump 5 is carried out without any problem.

Furthermore, if the periphery of the outer sole 2 is configured as described above, the periphery of the outer sole 2 can be easily deformed, and the inner sole 11 can be
The operation of compressing the support body 14 can be performed reliably in a short time.

Furthermore, since the pump 5 is provided with a ventilation pipe 9, the air (old air) inside the pump 5 can be reliably sent to the rear, allowing for more effective air circulation.

Furthermore, the structure of the pump 5, which is a component of the footwear according to the present invention, is as shown below as an example of the bacteria 2 described above.

An example of this is shown in Figures 5 and 6.
0 is formed by gluing together an upper plate 21 and a lower plate 22 shaped as shown in FIG. 6 at their peripheral parts, and an air chamber 23 is formed inside thereof.

In addition, a wedge-shaped gap 25 is formed near the inner side of the bonding surface as shown in the figure, and the upper plate 21 and lower plate 2
2, holes 24 and 24' are provided so as to be offset from each other.

Furthermore, an exhaust hole 26 is provided at the rear of the pump 20, and a ventilation pipe 27 is connected to the exhaust hole 26.

Incidentally, the upper plate 21 and the lower plate 22 are each made of a member having elasticity.

Therefore, if the pump 20 is placed between the gold outer sole 2 and the inner sole 11, the pump 20 will be crushed by the inner sole 11 fully pressing the pump 20.

At this time, the wedge-shaped gap 25 is sealed, and the holes 24 and 24' are closed by the periphery of the lower plate 22 and upper plate 210, respectively, so that the air in the air chamber 23 flows from the exhaust hole 26 to the ventilation pipe 27. sent out through.

When the pressure of the midsole 11 is released, the pump 20 returns to its original state due to its restoring force, and at this time air is absorbed from all the holes 24 and 24' around the pump 20.

In other respects, the operation is similar to that of the first embodiment.

Still another embodiment is shown in FIG.

As shown in FIG. 7, the pump 30 has a shape that fits the front part of the outer sole 2 of the footwear 1, and a wall part 31 is formed around the button.

Therefore, a recess 32 is formed inside the wall 31.

Grooves 33 are provided at predetermined intervals on the upper edge of the wall 31, and adhesive surfaces 34 are formed between the grooves 33.

Further, an exhaust hole 35 is provided at the rear of the pump 30, and a ventilation pipe 36 is connected to the exhaust hole 35.

It goes without saying that the material of the pump 30 is a material having elasticity.

The pump 30 constructed in this manner may be constructed as an independent pump by fixing an elastic member to the adhesive surface 34 of the pump 30, and may be installed at a predetermined position on the outer sole 2, as shown in FIG. It can also be used as follows.

In this case, the midsole 11 is fixed to the adhesive surface 34 to function as a lid of the pump 30.

In this case, the ventilation hole 12 is not provided in the portion of the midsole 11 located above the pump 30.

Further, the depth of the groove portion 33 is formed to a depth such that when the inner sole 11 is pressed, the groove portion 33 is sufficiently closed at the peripheral portion of the inner sole 11.

Therefore, in the above embodiment, if the inner sole 11 is depressed, the groove 33 of the pump 30 is closed and the pump 30 is crushed, so that the air in the recess 32 of the pump 30 is discharged from the ventilation pipe 36 through the exhaust hole 35. Sent out.

The other operations are the same as those of the other embodiments described above, so the explanation will be omitted.

Moreover, as yet another embodiment, there is one as shown in FIG.

As shown in the figure, the pump 40 has a rod-like U-shape, and it goes without saying that an air chamber is formed inside the pump 40.

Further, a hole 41 and an exhaust hole 42 are provided on the upper surface and rear end, and a ventilation pipe 43 is connected to the exhaust hole 42.

Note that the operation is the same as that of the pump 5 of the first embodiment, and a description thereof will be omitted.

As described above, according to the present invention, the hollow body works to take in the air in the footwear that has accumulated in the front of the entire midsection through the absorption hole and exhaust it reliably to the rear of the entire midway through the joint of the exhaust hole and the ventilation pipe. Therefore, ventilation of the front part of the footwear, which has a particularly bad air condition, can be carried out more effectively than in the past.

Therefore, it is possible to prevent moist air from stagnating around the front edge of the footwear and make the feet stuffy, which is extremely useful for foot health and hygiene.
