Description

[Detailed description of the invention] <Industrial application field> The present invention relates to the sole of a shoe, which has good breathability and
This invention relates to a sole that can improve comfort.

<Conventional technology> The sole of a shoe basically consists of an outer sole and an insole, and the outer sole is made of a material with poor breathability, such as rubber or plastic. Moisture builds up inside the shoes due to sweating in the shoes, causing stuffy feet and reducing the comfort of the shoes.
For this reason, conventionally, for example, a plurality of ventilation holes are provided near the treading part of the inner sole, and a hollow part having ventilation holes that communicates with the outside from the side is provided on the upper surface of the outer sole, and the hollow part has ventilation holes. A shoe sole fitted with an elastic body was used.

<Problems to be solved by this invention> The conventional shoe sole has a structure in which moisture generated from sweat inside the shoe is removed through ventilation holes drilled in the midsole through a breathable elastic material fitted to the upper surface of the outer sole. Due to the pressing force generated by the body weight when it is absorbed into the body and grounded,
The ventilation holes provided on the side of the outer sole allow the air to be discharged to the outside, eliminating stuffiness inside the shoe and improving comfort.

However, the ventilation holes on the side of the outer sole that lead to the outside are only drilled near the stepping area, and the pressing force from the body weight when touching the ground is not enough to achieve the intended purpose. However, it was not possible to reliably eliminate the stuffiness inside the shoes.

In view of the above circumstances, the present invention aims to provide a shoe sole that can reliably remove stuffiness caused by sweat inside the shoe.

<Means for solving the problem> The sole of the present invention for solving the above purpose is as follows:
It consists of a laminated body of an insole and an outer sole, and a plurality of ventilation holes are bored at appropriate locations in the insole. The structure is characterized in that a hollow part with a ventilation window is formed therein, and a breathable elastic body is fitted into the hollow part.

Further, a plate-shaped rigid body may be embedded on the upper surface of the breathable elastic body from the stepping part to the heel part.

In the above configuration, a plate-like body having greater elasticity than the breathable elastic body may be inserted directly below the ventilation hole between the breathable elastic body and the midsole, and The part may be provided with an inclined surface facing the ventilation window in a backward upward direction, and the front part of the upper edge of the heel part of the middle part may be provided with a slope so as to cover a part of the front part of the heel part of the middle part part. A solid sheet-like lid-like body may be provided.

As the breathable elastic body, a woven laminate of fibers, a non-woven laminate, an open cell foam of rubber or plastic, etc. are used as appropriate. As the lid-like body, a sheet made of synthetic leather, rubber, or plastic is used.

<Function> Moisture that causes stuffiness caused by sweating etc. is inhaled into the breathable elastic material on the lower surface of the insole through ventilation holes drilled at appropriate locations in the insole, but the inhaled moisture is absorbed by the wearer. The heel, where most of the weight is applied, has the greatest pressing force, ensuring that it is expelled from the ventilation window with force and reliably. This effect is further promoted by the greater thickness of the breathable elastic body in the heel region than in other parts.

The above-mentioned moisture is discharged to the outside more vigorously when a plate-like body of breathable elastic material is inserted directly under the ventilation hole of the insole due to the pressing force of the non-stepping part of the foot. However, even if water enters the heel of the middle part, covering it with the lid-like body at the front will prevent it from entering the interior, and the sloped surface facing the ventilation window will prevent water from entering the inside. It is also discharged outside.

<Example> A perspective view of the inner sole in FIG. 1, a perspective view of the outer sole in FIG. 2, a sectional view taken along line A-A' in FIG.
Figures 3-2, 3-3, and 3-4 are sectional views taken along line A-A' showing other application examples of Figure 3, perspective views of the breathable elastic body in Figure 4, and Figure 5. A cross-sectional view of the sole of the shoe shown in the figure.
A sectional view showing another application example of FIG. 5 in FIG. 5-2,
The following description will be made with reference to a perspective view of FIG. 6 showing another example of FIG. 4.

As shown in FIG. 1, an insole 1 made of rubber foam has a cotton fabric (not shown) attached to the upper surface and a plurality of ventilation holes 3 in the tread area, as shown in FIGS. 2 and 3. A solid outer sole 2 made of acrylonitrile butadiene copolymer rubber having a hollow part 6 which is deep at the heel part 4 and has a ventilation window 5 opened on the front side of the heel part 4, and a polyamide fiber as shown in FIG. Fabric (manufactured by Daiyu Co., Ltd., product name "Florian", heel thickness approximately 3 mm, other parts approximately 1.5 mm thick)
Prepare each heel part.

In this case, a shank 8 made of metal, wood, etc. may be embedded from the unstepped part of the upper surface to the heel part as shown in FIG. 6 to make walking easier and to prevent deformation. Next, the structure of the shoe sole will be explained with reference to FIG.

In this case, since the cover part is not directly related to the explanation of the present invention, it will be omitted in the drawings and explanation. A breathable elastic body 7 is fitted into the hollow part 6 of the outer sole 2, and the inner sole 1 whose lower surface is coated with adhesive is inserted into the ventilation hole 3.
is placed so that it is located on the treading part, and is adhered to obtain the sole of the present invention.

As an example of the application of the sole, as shown in Fig. 5-2, breathable material is provided on the lower surface of the ventilation hole 3 of the midsole 1 so that moisture can be easily discharged to the outside through the ventilation window 5 due to the pressing force of the foot stepping part. An elastic plate-like body 9 may be inserted, or the front part may be covered with a lid as shown in FIG. 3-2 to prevent water from entering the hollow part 6 and heel part 4 through the ventilation window 5. It may be partially covered with the shaped body 10, and the third-3
As shown in the figure, an inclined surface 11 may be provided facing the ventilation window 5, or as shown in FIGS. 3-4, an inclined surface 11 may be provided facing the ventilation window 5. At the same time as the lid-like body 10 is provided in the front part of the ventilation window 5, an inclined surface 11 may be provided facing the ventilation window 5.

<Effects> By employing the shoe sole with the above configuration in shoes,
Moisture that causes stuffiness caused by sweating while walking can be reliably discharged to the outside through the ventilation window 5 through the breathable elastic body 7.
Even if water gets in, it can be immediately discharged to the outside.
