Breathing insole with ventilating function

Abstract

This invention relates to a breathing insole with ventilating function, which is made of the shoe-shaped upper & lower insoles and porous layer; its features are as follows: when the upper insole is molded, the containing trough is made in concave in the central part of its bottom according to shape of shoe, frame around containing trough is also formed so that upper and lower insole are glued and form an air chamber. Several elastic protruding bodies are fixed in the arch of containing trough of this upper insole; porous layer contacting sole of the foot is glued onto upper insole. In addition, based on upper insole and porous layer, several inlet holes and outlet holes are respectively made in the heel portion and in the front thenar portion of foot; as the breathing insol with ventilating function is placed into shoes, the continuous trample and lift-up by the shoe wearer while walking may push cool air around the heel portion into the front thenar portion of the foot, the wet and hot air around the front thenar portion of foot inside shoe can be exhausted, therefore, shoes may keep ventilating and discharging heat effectively.

Description

BACKGROUND OF THE INVENTION [0001] 1) Field of the Invention [0002] This invention relates to a breathing insole with ventilating function, in which, a concave containing trough in the central part of the upper insole with frame is glued to the lower insole so as to shape an air chamber based on potential difference. Several elastic protruding bodies are fixed at the arch of containing trough of upper insole in order to fend off air chamber, so as to increase the room of air chamber, the upper insole and porous layer gluing onto upper insole and contacting the sole of the foot, several inlet and outlet holes are designed at the heel portion and the front thenar portion of the foot; thereby, the trample of the wearer, can circulate air to keep shoe ventilation. [0003] 2) Description of the Prior Art [0004] Usually, when the wearer put on shoes and socks, heat and sweat will be produced while walking. The inside air of the shoes is difficult to exhaust, when the temperature is high. T...

AI Technical Summary

Benefits of technology

[0006] The purpose of this invention is to provide a breathing insole with ventilating function, wherein a concave containing trough in the central part of the upper insole with frame, upper and lower insoles are glued together so as to shape an air chamber which is based on potential difference. Several elastic protruding bodies are fixed at the arch of the upper insole in order to fend off air chamber. The porous layer is glued onto upper insole, several inlet and outlet holes are designed at the heel portion and the front thenar portion of the porous layer and upper insole; thereby, trample of sole of the wearer can circulate air while walking, so as to keep shoes ventilation.

[0007] The second purpose of this invention is to provide a breathing insole with ventilating function, wherein the structure of this invention is simple and without any assistant component (such as air valve, air guide pipe), insole itself forms air chamber, and the insole is light & thin and large air contents, therefore, it can not only exhaust large quantity of air, but also is comfortable to wearer.

[0008] The third purpose of this invention is to provide a breathing insole with ventilating function, wherein, the molding of the upper insole of this invention can save workload and material, its cost of production may be reduced.

[0009] The fourth purpose of this invention is to provide a breathing insole with ventilating function, When a concave containing trough in the central part of the lower insole with frame, and concave containing trough can be designed equally distributed protruding points in the lower insole and the porous layer are glued together so as to shape an air chamber. Several elastic protruding bodies are fixed at the arch of the lower insole in order to fend off air chamber, several inlet and outlet holes are designed at the heel portion and the front thenar portion of the porous layer; thereby. The wearer can be easier to exhaust moist muggy air on foot while walking, so as to keep shoes ventilating more effectively.

Problems solved by technology

Usually, when the wearer put on shoes and socks, heat and sweat will be produced while walking.

The inside air of the shoes is difficult to exhaust, when the temperature is high.

However, this model of product has limited air contents due to small fend-off envelope, the thickness of insole must be increased if you want to add air contents, so, it isn't applicable for common shoes.

The envelope supported by such sponge elastic body uses interval of sponge to contain air, so, its air contents may be reduced, and this supporting body may be fatigued due to the extrusion of the wearer weight.
