Abstract

PROBLEM TO BE SOLVED: To solve the problem that a harmful influence by sweatiness of the foot inside shoe is serious especially in a high-temperature/high-moisture season in the summer in normally worn shoe, and the back of the foot at a sweated part needs to breath air to solve the problems.SOLUTION: Sufficient breathing is required to prevent sweatiness in the foot inside the shoe. Therefore, a vent is provided in an outer periphery at a lower part of outer leather and an insole in an inner sole is spread at the same height as the vent to circulate air to the back of the foot via the vent. Columnar projections are formed in an entire upper part of the insole in the inner sole and a gap between the columnar projections and air in the vent become integral, thus breathing air fully as in a draining plate. This function solves the problem of the sweatiness of the foot. To prevent the penetration of dust and water from the vent, fabric and a moisture-permeable sheet are stretched at the vent portion to prevent dust, or the like.

Description

  The present invention relates to a mechanism in which a shoe outer leather and a foot installation surface of footwear have a ventilation function.

  In hot and humid countries, footwear has changed from clogs to shoes with covered feet, which has been plagued by odors caused by stuffiness. In order to solve this problem, many people have devised a covering, ventilation and ventilation shoes.

The invention described in Patent Document 1 provides a shoe in which an air passage and a slit are provided in a shoe sole insole portion so as to ventilate the feet, thereby eliminating foot stuffiness.
However, the shoe having a ventilation function of the invention of Patent Document 1 is predicted to have a complicated structure of the air introduction passage, a long passage, and a small amount of air introduction. In addition, when the soles are directly on the insole, ventilation from the slits is insufficient and sweat on the soles is stuffy.

The breathable shoe according to the invention described in Patent Document 2 uses a breathable member for the upper and the sole portion, and provides a shoe for venting moisture on the back of the foot to the outside by providing a vent on the sole.
However, the breathable shoe of the invention of Patent Document 2 uses a sponge-like member that exists as a conventional cover for the breathable member, and may be compressed by the soles to impair the ventilation function.

Japanese Patent Application No. 2009-268857 Japanese Patent Application No. 2009-39518

Among the shoes related to the conventional ventilation function described above, shoes that can provide sufficient ventilation against the stuffiness of the foot, particularly in the summer, are sought.

In order to achieve the above object, the present invention provides a vent hole having both practical use and a costume on the outer periphery of the lower part of the upper, and lays the insole skin at the same height as the vent hole. The insole skin forms a columnar protrusion on the entire upper surface, and like a snowboard board, the feet are floated on the surface of the columnar protrusion, so that the gap between the columnar protrusion and the vent hole part are integrated and the wind passes sufficiently, inside the shoe The sole of the foot is always in contact with the ventilation surface. This function is enough to process the shoes.

By the above solution, the entry of dust or the like can be prevented by attaching a cloth or a moisture permeable sheet to the ventilation hole portion for the purpose of preventing dust, insects, and water from entering inside the shoe which allows sufficient ventilation.

  As described above, according to the present invention, air flows through the function of the insole cover having a vent hole and a columnar protrusion in the shoe body, and it is possible to prevent the soles from being stuffy. The bad effects caused by stuffiness inside the shoes worn in summer can be solved by the columnar projections applied to the board. In addition, dust and water can be prevented from entering by placing a cloth or a moisture permeable sheet on the vent hole.

Claims (3)

  In the present invention, vents are provided on the outer periphery of the lower part of the outer leather for the purpose of ventilating the soles and the inside of the shoes, and in order to prevent rainwater intrusion, the vents are sloped. In the shape of the vent hole, it may be a round hole, a long hole, or a designed figure as shown in FIGS. Summer shoes with a vent on the outer leather.   The present invention forms columnar protrusions on the entire upper surface of the insole laying laid at the same height as the ventilation holes for the purpose of distributing ventilation through the ventilation holes to the soles and shoes, and in the gaps between the columnar protrusions. Ventilation occurs when air flows and matches the vent. The shape of the columnar protrusion is a columnar shape or a polygonal shape as shown in FIG. 2 and has a surface area where the foot does not sink. Arrangement, random, etc. may be sufficient as arrangement | sequence so that ventilation | gas_flowing can flow freely. The insole skin of the present invention is a single-piece molding, and may be affixed to the shoe sole, or may be inserted in the same manner as a conventional insole. The summer shoes according to claim 1, which have a ventilation function by an insole skin having columnar protrusions.   The present invention is intended to prevent dust and water from entering the shoe through the vent by stretching a colored fabric or moisture permeable sheet on the inside or outside of the vent portion according to claim 1. Item 1. A summer shoe according to item 1 or item 2.
