Abstract

PROBLEM TO BE SOLVED: To obtain a shoe insole having excellent sterilizing power and the good touch to the feet by forming a base fabric and front fabric of towel cloth and intervening an inner fabric knitted of jute yarn and a net body contg. copper between both fabrics. SOLUTION: The inner fabric 2, the net body 3 and the front fabric 4 are superposed successively from below on the base fabric 1. The base fabric 1 and the front fabric 4 consist of the towel cloth of pile weave, etc. The inner fabric 2 is formed by knitting the jute yarn and the net body 3 by knitting the copper wires. The respective layers 1 to 4 are covered with end fabrics 5 at their end edges and are sewn to each other by sewing threads 6. If a person puts on the shoes laid with such shoe insoles on the inner sole, the moisture generated from the feet is absorbed in the front fabrics 4 and a slight amt. of the copper elutes from the knit 3 into this moisture. This copper is ionized to suppress the propagation of bacteria in the shoes. The moisture permeated through the knit 3 is absorbed in the inner fabrics 2. The inner fabrics 2 are increased in the strength and elastic force when the fabrics absorb the moisture. The impact accompanying walking is absorbed and the rupture of the base fabrics 1 and the front fabrics 4 is prevented.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a shoe insole laid on the insole of a shoe.

[0002]

2. Description of the Related Art Heretofore, there has been known a sock insole in which activated carbon is contained in a base material made of foamed rubber or the like to have a deodorizing effect and a cushioning property is improved.

[0003]

However, in the above-mentioned insole, the effect of suppressing the growth of bacteria inside the shoe is poor, and the feel of the foot is not so good.

Therefore, an object of the present invention is to provide an insole which is excellent in sterilizing power and has a good feel.

[0005]

SUMMARY OF THE INVENTION In order to solve the above problems, the present invention comprises a base cloth and a surface cloth formed of a towel cloth, and a middle cloth knitted with hemp yarn between the two cloths and a copper cloth. That is, a layered structure including a net body containing is adopted.

[0006]

Embodiments of the present invention will be described below with reference to the accompanying drawings.

As shown in FIGS. 1 and 2, an inner cloth 2, a net body 3 and a front cloth 4 are superposed on a base cloth 1 in order from the bottom. The base cloth 1 and the outer cloth 4 are made of a towel cloth such as pile weave, the inner cloth 2 is made of hemp thread, and the net body 3 is made of copper wire. Each of the layers 1 to 4 has an edge covered with a hem cloth 5 and is sewn to each other with a sewing thread 6.

When wearing a shoe in which the insole having the above-mentioned structure is laid on the insole, the water generated from the foot is absorbed by the surface cloth 4, and a small amount of copper is eluted from the net 3 into the water to be ionized. And suppresses bacterial growth inside the shoe.

Moisture that has permeated the mesh 3 is absorbed by the inner cloth 2. When the middle cloth 2 absorbs water, its strength and elasticity increase,
It absorbs the impact of walking and prevents the base cloth 1 and the outer cloth 4 from breaking. Further, if an appropriate gap is provided between the hemp threads of the inner cloth 2, air permeability is secured.

In addition, since the sole of the foot comes into contact with the outer cloth 4 made of a towel cloth, a good feeling can be obtained.

As the net body 3, when a copper wire and a stainless wire are superposed and used.
Since stainless steel has lower thermal conductivity than copper, heat retention is improved. Further, the same effect can be obtained by forming a net body 3 by braiding a copper wire and a stainless wire.

[0012]

As described above, according to the present invention, the trace amount of copper ions eluted from the net body suppresses the growth of bacteria, so that the inside of the shoe can be kept hygienic.

Further, since the base cloth, the inner cloth, and the outer cloth are each made of a material having excellent hygroscopicity, it is possible to prevent the foot from slipping.

Furthermore, since the outer cloth is made of a towel cloth, it feels good on the feet, and the inner cloth absorbs the shock caused by walking, so that the shoes are less tired even when worn for a long time.
