[0005]

SUMMARY OF THE INVENTION The inventor of the present invention has provided a ventilation hole at the most damp part of a shoe for ventilation so that water does not come into contact with the foot even if water enters along with air through the hole. I thought that there would be no problem in practice and ventilation could be done efficiently if it was done. That is, on the surface of the shoe near the sole of the shoe, a hole is formed that serves as an opening to the outside of the air passage, and

According to a third aspect of the present invention, there is provided a flat bag-shaped member which is a separate body from the opening to the outside provided on the side surface of the shoe sole of the toe portion or on the side surface of the shoe near the shoe sole, and the shoe constituent member. One end communicates with the opening, the other end opens in the upper part of the shoe near the toes, and an air passage is provided in the gap between the foot such as fingers in the shoe and the inner wall of the shoe. From the inside to the inside of the shoe is prevented by the drop of the air passage, and the air is allowed to pass freely to ventilate the air inside the shoe and the outside air.

[0012]

In general, the toes of short shoes and boots tend to get stuffy. This is because the humidity in the shoe rises due to the sweat from the foot, and the reason why the humidity rises is that it is difficult for the outside air to enter the gap between the foot of the toe and the inner wall of the shoe. However, if you look closely, the air in the gap between the toes moves as you walk.
This is easily imagined because the foot moves slightly back and forth in the shoe, and when only the heel leaves the ground, the upper skin deforms from the toe to the instep, increasing or decreasing the gap near the toe. it can. If the gap between the toes becomes smaller, the air moves by the volume of the toe, but if the volume of moving air is smaller than the volume of the gap up to the mouth. The air in the toe part will be pulled back to the toe part the next moment before it goes out from the mouth opening. After all, the air in the toe part only moves back and forth inside the shoe, and does not go out of the shoe, so it does not ventilate.

Therefore, if an air passage having a volume smaller than the volume of the moving air is provided, a part of the moving air will go out, and the outside air will be sucked in by the amount of the discharged air, so that it should be ventilated. Is. However, if the air passage is thin and long and has a large air resistance, the air in the gap will flow toward the slippery mouth, which is easy to flow as before, and will not provide ventilation. Therefore, the air passage should have a low air resistance so that the air in the gap can easily flow to the newly provided ventilation hole rather than to flow to the shoe opening. Actually, when measuring the volume of the gap between the toes with a certain shoe, the volume of the gap between the foot and the shoe when the foot moved forward was 20, and the volume of the gap when the foot moved backward was 38. The amount of air moved by the forward and backward movements of the foot was 18. Also, the volume of the clearance between the foot and the inside of the shoe changes due to the vertical movement of the heel and the vertical movement of the toe, and this volume change causes changes in atmospheric pressure at various parts inside the shoe, which also causes air flow. .

The inventor of the present invention wondered if an upward air passage could be installed in the gap between the foot and the shoe at the toe portion. In this way, water and air are separated in this air passage. Only the air will get into your shoes. On the other hand, in the toe part, as a place to attach an upward air passage, a discarding part at the tip of the toe, a gap between the fingers on both sides of the toe and shoes, a gap between the toe of the toe and the base of the forefinger, etc. were found. It was Since these places are close to the part that gets damp, the air passage can be shortened. Further, a relatively large air passage could be provided in the space between the first joint and the second joint of the big toe having a relatively large gap and the shoe. Since these gaps vary greatly depending on the type of shoe and the shoe type, when providing an air passage for a ready-made shoe, it is necessary to select a place where the air passage is hard to hit the foot.

Further, in the case of a shoe in which the tip of the upper is easily bent and deformed when only the heel is separated from the ground during walking, the bending deformation of the tip of the upper causes an increase / decrease in the clearance near the toe. Since it is relatively large, the amount of air movement increases, and the ventilation improves accordingly. In addition, by making the air passage into a tunnel type or by arranging several small tunnel types, it was possible to prevent the air passage from being blocked even when the air passage was bent or pushed by the foot. In addition, the holes made in the bag-shaped air passage and the holes made in the upper are connected with a eyelet to caulk them, waterproofing the joint surface between the upper and the air passage, and It was possible to waterproof and fix the air passage to the upper skin at the same time.

Further, the inner surface of the flat bag-shaped air passage member 7 is preferably made water-repellent.

FIGS. 5 and 6 show another embodiment of the third aspect of the present invention, which is a flat bag-shaped air passage member 7 formed so that the opening of the air passage is fitted into the hole formed in the shoe. Here is an example. FIG. 7 shows still another embodiment of claim 3 in which a lateral bag 8 formed in a shoe sole 12 has a hole 9 for mounting a flat bag-shaped air passage member 7, and the air passage member 7 is fitted therein. It is fixed. Also in this embodiment, it is preferable that the inner surface of the flat bag-shaped air passage member 7 has water repellency.

FIG. 8 shows an embodiment of claims 4 to 6, in which a flat air passage member 7 is attached by eyelets 10 to holes formed in the upper 13 of the toe of the shoe. This flat air passage member 7 is made of synthetic resin such as vinyl, rubber,
It is made of a flexible material and has an upper part opened to form an opening 3 into the shoe, a lower part closed, and an opening 2 to the outside formed on one side lower part, which is caused by bending of the upper 13 during walking. In order to prevent the air passage from being crushed and blocked, a tunnel type cavity is provided as shown in FIG. 9A, or a blocking prevention rib 7a is provided as shown in FIG. 9B. Further, as shown in FIG. 9C, the flat air passage member 7 is installed in a continuous arch shape from both sides of the inner bottom of the shoe to the upper part along the upper 13 and has an opening into the shoe at the upper part. It is also possible to form an appropriate number of parts 3. In this case, the installation position of the air passage member 7 uses a gap formed near the boundary between the instep and the finger. Although FIG. 8 exemplifies the case of boots, the same applies to boots as well. In the case of boots, the prevention of stuffiness can be further improved by attaching the air passage members to the toe portion and the arch portion in the above manner. Further, the flat air passage members 7 may be manufactured one by one, but it is also possible to manufacture a long one and cut it for use. Further, when the flat air passage member 7 is attached to the upper 13 with the eyelets 10, a plurality of eyelets 10 may be used.
