Description

[Detailed Description of the Invention] <Industrial Application Field> This invention relates to a shoe insole that is placed on the sole of a shoe to improve air permeability inside the shoe.

<Prior Art> As is well known, when shoes are worn for a long period of time, the inside of the shoes become stuffy due to perspiration, which not only causes a bad odor, but also poses a risk of contracting diseases such as athlete's foot. It was extremely unpleasant.

To address this problem, many shoe insoles have been proposed to be placed on the inner surface of the shoe sole.

Typical configurations of this shoe insole include, for example, a structure in which a large number of small holes are formed vertically through the insole, or a plurality of grooves are provided on the bottom surface, and a large number of small holes are formed in the grooves in a vertical direction. It was opened through.

These are intended to improve breathability to the soles of the feet when worn on shoes.

<Problems to be solved by the invention> However, these conventional examples have the following problems.

That is, if a large number of small holes are simply opened in the vertical direction, these small holes are always closed between the upper surface of the sole and the sole surface of the foot, and therefore, hardly any ventilation effect can be expected.

Also, in the case of shoes having grooves on the lower surface, the open ends of the grooves are blocked by the inner surface of the upper of the shoe, and therefore, there is no sufficient ventilation effect.

If you use an insole that is one size smaller than the shoe size, a gap will be created between the inner surface of the upper and the peripheral edge of the insole, and from this gap, outside air will flow into the inside through the small hole through the groove. However, in this case, the insole shifts internally every time you walk, which not only makes it uncomfortable to wear, but also causes the socks to shift and tear easily.

<Means for solving the problem> The present invention was devised to solve the above-mentioned problems.In addition to providing a large number of notches at the peripheral edge of the insole material, the lower surface of the insole material has edges. A large number of ventilation grooves are provided in which the part communicates with the notch, and the ventilation groove further includes:
It is constructed by opening a large number of holes on the upper surface of the insole material.

<Function> Since the present invention has the above-described configuration, outside air flows into the inside of the shoe through the hole through the groove from the notch at the peripheral end of the insole material, maintaining breathability and maintaining a good condition. can do. Furthermore, moist air inside the shoe, particularly in the sole area, is exhausted to the outside through the inner surface of the upper in the opposite direction.

Furthermore, the inner surface of the upper skin and the side surface of the foot are not in close contact with each other, and the gap between the inner surface of the upper skin and the side surface of the foot may widen or narrow, especially during complex movements of the foot during walking. Therefore, this operation functions as an air pump and promotes the air flow from the notch to the sole of the foot, thereby preventing the foot from becoming stuffy and causing bad odors.

On the other hand, since the part of the peripheral edge of the insole material that is not cut out is in contact with the inner surface of the upper, the insole will not shift inside the shoe when worn. , without compromising comfort.

Since the notch is provided at the peripheral edge of the insole material and is not in direct contact with the sole of the foot, it does not interfere with the above-mentioned air supply and exhaust function, and
You won't feel any foreign body sensation on the soles of your feet, and you won't feel any pain.

<Example> The present invention will be explained below based on the drawings of the example.

First, the insole material 1 is a plate-shaped body made of hard synthetic rubber, semi-hard synthetic resin, etc., and has a roughly gourd shape corresponding to the upper surface of the sole of the shoe.
A large number of notches 3 are provided in the.

Therefore, the circumferential edge of the insole material 1 is alternately formed with portions that come into contact with the inner surface of the upper and portions where gaps are formed between the inner surface of the upper and the inner surface of the upper due to the notches 3.

A large number of ventilation grooves 4 are provided on the lower surface of the insole material 1, the ends of which communicate with the notches 3 described above, and a large number of through holes 5 that open on the upper surface of the insole material 1 are further provided in the ventilation grooves 4. It is opened in the thickness direction of the insole material 1.

If both ends of the ventilation groove 4 are blocked, the air supply and exhaust action will not be performed effectively, so the ventilation groove 4
At least one end of the cutout 3 is communicated with the cutout 3. However, if a large number of ventilation grooves 4 are provided so as to intersect with each other, it is not necessary that all the ventilation grooves 4 communicate with the notch 3.

The form of the ventilation grooves 4 may be provided vertically and horizontally as in the illustrated embodiment, or a large number of them may be provided along the length direction.
Alternatively, they may be provided parallel to the width direction, further radially, linearly, or curved.

Although the present invention has been described above with reference to the embodiments shown in the drawings, the present invention is not limited to the above-described embodiments, and may be implemented in any manner as long as the configuration described in the claims for utility model registration is not changed. can.

For example, if the notch 3 is provided in the toe portion of the insole material 1, the tip of the finger comes into contact with the foot when walking, which tends to create a sense of discomfort. For this reason, either make the cut smaller or
It may not be necessary to form it.

<Effects of the invention> In summary, according to the invention, the structure is simple and can be easily molded, and the ventilation inside the shoe can be improved, suppressing the emission of bad odors and making it hygienic. As a result, it does not impair health, is comfortable to wear, and has a high commercial value with an interesting design due to the notch at the peripheral edge.
