[Detailed description of the device]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an insole of footwear such as shoes and sandals.

[0002]

2. Description of the Related Art Footwear insoles made of a flexible material such as leather, synthetic resin or cloth are generally used.

[0003]

The conventional footwear insoles described above are not necessarily satisfactory in terms of breathability and cushioning. Therefore, the present invention has been made to provide an insole for footwear having sufficient breathability and cushioning properties.

[0004]

In order to solve the above-mentioned problems, the present invention is to fix a sponge plate having a large number of through holes on a substrate, and fix a urethane foam plate on the sponge plate. Provided is an insole for footwear, characterized in that a surface cover having a large number of small holes is coated on the urethane foam plate.

[0005]

The footwear insole according to the present invention is incorporated into the footwear sole like a conventional footwear insole. When walking with footwear incorporating the insole according to the present invention,
The weight of the user is alternately applied to the insoles of the left and right footwear. That is, the insoles of the left and right footwear are repeatedly pressed and released by the weight of the user. In other words, the insole of each footwear is pressed by the weight of the user to compress the sponge plate and the urethane foam plate on the substrate, and then the pressing is released to separate the sponge plate and the urethane foam plate on the substrate. The elasticity returns to the original state, and this is repeated as the user walks. Then, when the sponge plate and the urethane foam plate on the substrate are compressed, the air in each through hole of the sponge plate and the air in the bubbles of the urethane foam plate are pushed out and pass through the small holes of the surface cover to the outside. Go to. By the way, since the holes of the surface cover are small holes, the air in each through hole of the sponge plate and the air in the bubbles of the urethane foam plate receive resistance when passing through the small holes of the surface cover. That is, the insole of the present invention acts as an air cushion when pressed by the weight of the user. On the other hand, when the pressure due to the weight of the user is released and the sponge plate and the urethane foam plate on the substrate return from the compressed state to the original state due to elasticity, the outside air passes through the small holes of the surface cover and the sponge plate is blown away. It re-enters each through hole and the bubbles of the urethane foam plate. In summary, when the user wears footwear incorporating the insole according to the present invention and walks, the insole functions as an air cushion and as a ventilator.

Embodiments of the present invention will be described below with reference to the accompanying drawings. Reference numeral 1 indicates a substrate of the insole.
The substrate 1 is formed of a hard material such as synthetic resin. On the substrate 1, a sponge plate 3 having a large number of through holes 2, 2, ... Is fixed. Each through hole 2 of the sponge plate 3 penetrates the sponge plate 3 in the vertical direction and has a diameter of, for example, several mm. On the sponge plate 3, a urethane foam plate 5 having a large number of small bubbles is fixed. A surface cover 8 having a large number of small holes 7, 7 ... Is coated on the urethane foam plate 5. The surface cover 8 is, for example, a soft and thin synthetic resin cover, and has a large number of small holes 7, 7 ... Each small hole 7 has, for example, a diameter of 0.
It is about 5 to 1.5 mm. Reference numeral 9 is an outsole.

[0007]

As described above, when walking with the footwear incorporating the insole according to the present invention, the insole functions as an air cushion and as a ventilator. That is, the insole according to the present invention is extremely excellent in cushioning property and not only provides a very comfortable wearing feeling, but also secures sufficient air permeability, so that when the insole is applied to shoes, it can be used at high temperature and high humidity. It is extremely comfortable and has the effect of preventing athlete's foot.
