Description

[Detailed explanation of the idea] (Industrial application field) The present invention relates to improvements in shoe insoles.

(Prior Art) Shoe insoles are generally required to have various properties such as breathability, moisture absorption, heat retention, moisture release, durability, and low cost. As described in Japanese Patent No. 61-18731, it was necessary to laminate a large number of materials having various properties.

(Problems to be solved by the invention) In general, the above-mentioned properties required for shoe insoles are not required for the entire surface of the shoe insoles, but for the tread area corresponding to the base of the toes and the arch of the foot. Among the requirements for the corresponding non-stepping part and the heel part corresponding to the heel, the requirements for various properties in the stepping part are especially high.

However, like the conventional shoe insole, the insole is constructed by laminating a large number of materials with each property in order to obtain the above properties over the entire surface of the insole, which increases the material cost. Not only that, the entire shoe insole becomes thicker, and when placed inside the shoe, it dulls the sensation of ground contact on the sole of the foot, and it also makes the shoe uncomfortable to wear, such as by narrowing the inner volume of the shoe, making it cramped. There was a problem.

The present invention was developed with an eye to these problems, and has excellent breathability, moisture absorption, heat retention,
Despite being moisture wicking and durable, it is thin overall and eliminates the feeling of tightness caused by using an insole, provides a good ground feel, is comfortable to wear, and has a stylish design. It is an object of the present invention to provide a shoe insole that can be made into a novel form.

(Means for solving the problem) In order to achieve the above object, the insole of the present invention has the following features:
The insole is mainly made of hygroscopic synthetic leather and is formed approximately in the shape of a foot, including a stepping part corresponding to the base of the toes of the sole, a non-stepping part corresponding to the arch of the foot, and a heel part corresponding to the heel. A ventilation hole is provided at least in the tread portion, and the ventilation hole is welded to be closed with a ventilation polymeric member made by sandwiching a cushion material such as a sponge with a mesh sheet.

(Example) Next, an example of the shoe insole of the present invention will be described below based on the drawings.

FIG. 1 is a plan view of an insole for a high-heeled right foot according to an embodiment of the present invention, and FIG. 2 is a sectional view taken along line A--A in FIG. 1.

1 in the figure is the main part of the insole, which is made of synthetic leather such as Clarino (registered trademark, Kuraray Co., Ltd.), with a stepping part C corresponding to the base of the toes on the sole of the foot and a non-stepping part corresponding to the arch of the foot. D and a heel portion E corresponding to the heel, and is formed approximately in the shape of a foot. In particular, the stepping portion C has ventilation holes 2 over a wide area, and the non-stepping portion D has many small holes. It has a configuration in which a hole 3 is bored.

4 is a breathable elastic member, and the insole main body 1
Cushion material 5, such as urethane sponge, is cut to be large and similar to the ventilation hole 2 of the tread portion C.
is sandwiched between two vinylidene chloride net woven fabrics 6a and 6b, and this breathable elastic member 5 is polymerized so as to close the ventilation hole 2 from the contact surface side of the insole main body 1. They are integrated by welding 7 their peripheral edges.

The above shoe insole is similar in size to the insole main body 1 and the ventilation holes 2 in the tread area C, which are formed at the same time when punching out the ventilation holes 2 and a large number of small holes 3 into the shape of the shoe insole. After punching and forming the breathable elastic member 4 made by sandwiching the cut cushion material 5 with two sheets of polyvinylidene chloride net woven fabric 6a and 6b, as described above, the breathable elastic member 5 is used as the main insole. It is manufactured by overlapping the ventilation holes 2 from the contact surface side of the parts 1 and welding their peripheries to integrate the two.

In the above example, Clarino (registered trademark, Kuraray Co., Ltd.) was used as the insole main body 1, but it is possible to use synthetic leather with similar properties, such as Hiteratsuk (registered trademark, Toray Co., Ltd.). Needless to say.

In addition, as shown in Figures 3 and 4, synthetic leather such as Clarino (registered trademark, Kuraray Co., Ltd.)
The sole of the foot is formed into a substantially foot shape including a stepping part C corresponding to the base of the toes, a non-stepping part D corresponding to the arch of the foot, and a heel part E corresponding to the heel,
An insole main body 1a is formed in which ventilation holes 2, 2a are opened over a wide area of the stepped part C and the non-stepped part D, and the ventilation of the stepped part C and the non-stepped part D of the insole main body 1a is formed. In some cases, breathable elastic members 4, 4a are welded to the insole main body 1a to close the holes 2, 2a, and a cushion material 5a is bonded to the heel E.

(Operations and Effects of the Invention) The shoe insole of the invention described above is made of hygroscopic synthetic leather, and is made of synthetic leather that has moisture absorption properties, and is made of synthetic leather that has moisture absorption properties, and is made of synthetic leather that is hygroscopic. A ventilation hole is provided at least in the stepping part of the insole which is formed into a substantially foot shape including a heel part corresponding to the heel part, and the ventilation hole is closed with a ventilation polymeric member made by sandwiching a cushion material such as a sponge with a mesh sheet. Since the synthetic leather is welded as much as possible, the moisture absorption properties of the synthetic leather are ensured, and the breathability, elasticity, moisture release properties, and durability that are most required for the tread area are effectively exerted, and these properties are exhibited. In addition, the overall thickness of the insole is thinner, which eliminates the cramped feeling caused by using an insole, improves the feeling of ground contact, and makes the structure simpler. Therefore, it is possible to achieve the effect of being easy to manufacture and providing at low cost.

In addition, since the entire shoe insole is thin, the storage volume is small, which not only improves the economy of storage and transportation, but also allows a large number of shoe insoles to be displayed in a narrow hanging sales space.

As described above, according to the present invention, the overall shoe is thin, and the feeling of tightness and poor ground contact caused by using insoles is eliminated, and the shoe has good breathability, moisture absorption, heat retention,
To provide a shoe insole having excellent moisture releasing properties, durability and comfort at a low cost.
