VENTILATED OUT-SOLE OF SHOES WITH IMPROVED STRUCTURE}

The present invention relates to a breathable shoe sole of an improved structure, and more particularly, to improve the productivity, adhesiveness and durability while allowing the shoe sole to be breathable to extend the service life and to reduce the manufacturing cost at the same time anti-slip and A breathable shoe sole having an improved structure to improve cushioning properties.

In general, shoes are used for the purpose of protecting the feet, and these shoes have changed and developed in various designs and functions with the change of times and fashions. The trend that emphasizes the functionality of the shoes has been created, and most of the shoes have emphasized ventilation and drainage.

Recently, as a part of preventing and / or treating foot odor, eczema and athlete's foot, technology development has been progressed to keep the inside of the shoe clean through the introduced air by introducing fresh air into the shoe. For example, patent document 1-patent document 3 of a prior art document are mentioned.

Referring to each of the patent documents in more detail, Patent Document 1 is provided with an upper surface in contact with the lower portion of the shoe body or midsole, at least one of the passageway in the form of a 'V' groove in the longitudinal direction on a part or the entire surface of the upper surface Or a plurality is formed, the back of the air passage is formed with an inclined upwardly to the rear and the bottom surface is inclined downward from the center to the outside is provided with a breathable outsole having a rim of a predetermined width around the upper surface, while the outsole is applied breathable shoes Silver, the shoe body is attached to the upper surface of the breathable outsole, the insole is embedded in the shoe body, the insole proposed a 'breathable outsole' doubled breathable by weaving a synthetic resin net.

In addition, Patent Document 2 is provided with a lower surface in contact with the sole and the sole contacting the shoe body and at least one or a plurality of 'V' shaped grooves in the longitudinal direction on the part or the entire surface of the upper surface is formed, The rear surface of the upper slope is formed and the bottom surface is inclined downward from the center to the outside is provided with a breathable midsole having a rim of a predetermined width around the upper surface, while the breathable shoe to which the midsole is applied, the upper surface of the breathable midsole Shoe body is attached to the sole is attached to the sole and the insole is inherent in the shoe body, the insole proposed a 'breathable midsole and the shoe with its midsole' is doubled breathable by weaving a synthetic resin net.

In addition, Patent Document 3 has a structure similar to a fishbone (fishbone), that is, the backbone and rib structure of the fish, while the rib pressure structure and rib structure can be effectively distributed and accommodate the pressure that the sole presses A fishbone type shoe sole has been proposed that allows for good ventilation and the exchange of heat and moisture according to the space between them.

However, since the patent literature is an uneven structure in which the sole and the support are integral and the V-shaped support is repeated, the soles of the shoe are covered, even if the insole of the shoe is covered, the feet are injured when worn, and the flesh or corn on the sole may occur. There is such a problem.

In addition, the patent documents form a portion where the shoe upper is bonded to the sole edge, but when the mold for manufacturing the part has a lot of undercut structure, the slide core attached to the mold is used a lot, in this case the mold structure is very complicated, manufacturing cost This will happen a lot.

Even if a mold with a complicated structure is manufactured at a high cost, if the slide depth exceeds 5mm in the process of extracting the molded sole due to the slide core attached to the mold during injection, the molded sole can be detached from the mold. Productivity decreases due to the increase in defective products, and when manufactured to about 5mm, the adhesion area between the upper and the sole is too narrow, so that the upper and the sole are not completely adhered, and the sole and the upper easily fall.

Moreover, when the air passage is stopped in the V-shape as in Patent Documents 1 and 2, the communication of air is insignificant when it is stopped, and when the air passage is formed in the I-shape as in Patent Document 2, the air inflow is insignificant when walking.
