Abstract

PROBLEM TO BE SOLVED: To make the inside of a shoe not stuffy in order to prevent a foul smell from being generated by fixing molded pipes made of a resin to the underside of an insole, arranging the pipes from a heel section to a tiptoe section in a direction generally normal to the length of the insole and forming vents in the insole. SOLUTION: As a material of an insole 3 that will be placed in a sole, a pressed board is used. The pressed board is cut into the shape of one's foot and polyvinyl chloride pipes 4 resistant to bending are attached to the underside of the cut board on the side opposite to the foot contact side to form a cushionlike breathable insole 1 with pipes. The polyvinyl chloride pipes 4 are arranged in a direction generally normal to the length of the insole 3 from a heel section to a tiptoe section of the insole 3. A suitable number of holes acting as vents 5 for circulating air in a shoe are formed between the pipes 4. An upper cloth and an intermediate cloth cut in a separate step are sewn into a bag to form a shoe upper. A polyurethane resin as a sole material is injected to mold the shoe upper and the sole integrally.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a ventilated shoe which prevents bad odors and athlete's foot caused by perspiration of the foot by improving the air permeability of the inside of the shoe and preventing stuffiness.

[0002]

2. Description of the Related Art The main body of a shoe sole of a shoe is composed of an outer sole and an inner sole. The outer sole is made of a material having poor air permeability such as rubber or plastic, and is long regardless of the season. The inside of the shoe becomes hot and humid due to sweating from the foot during wearing for a long time. Therefore, the foot becomes extremely stuffy, which is extremely uncomfortable for the wearer,
It will be uncomfortable.

However, as a means for preventing the stuffiness of the shoes, the interior is made of a material having a hygroscopic property, a highly breathable mesh fabric is used as the material of the instep, or a pump is attached to the sole of the shoe, and Some have provided a vent that communicates with the interior of the shoe to prevent stuffiness by using a method of forced air circulation.

Further, the hot air in the shoes due to sweating of the feet,
An insole that has been devised to absorb moisture has been proposed, and it has some effects. As an insole which is relatively effective among these, it is composed of a laminated body of cloth or leather etc. and a foam, and a groove capable of communicating with each other is formed on the surface of the foam, and an appropriate portion of the groove is formed. There has been proposed an insole or the like in which ventilation holes are formed so as to vertically penetrate the multilayer body.

[0005]

As described above, the use of a material having a hygroscopic property in the prior art, the adoption of a mesh material having a high air permeability as a material for the instep, etc. is relatively ineffective and inferior in fashionability. Therefore, it has not reached full-scale spread. In addition, the method of mounting the pump inside the sole of the shoe increases the manufacturing cost of the device and causes a cost increase.
Further, if the pump malfunctions during wearing, maintenance is not easy, and finally the air cannot be blown.

In the case of the above-mentioned insole, perspiration on the foot portion is small when worn for a short period of time, and heat and humidity are not so much generated in the shoe. Therefore, the wearer is not so discomforted, but when worn for a long time, a large amount of hot air or moisture is filled in the shoe. In this way, it is not possible to sufficiently remove hot air and moisture only with the grooves and the ventilation holes, and it is not possible to reduce the discomfort of the wearer.

[0007]

[Means for Solving the Problems] A ventilation insole with a pipe, in which a pipe made of a resin is fixed to the lower surface side of the insole by an appropriate number of adhesives from the heel to the toe approximately at right angles to the longitudinal direction. Insert it into the void of the shoe sole and provide an appropriate number of intake and exhaust holes on both sides of the side tape part of the stepping part of the shoe sole to circulate the hot and humid air inside the shoe and the fresh air outside. This prevents stuffy feet.

[0008]

[Function] The resin pipe mounted inside the shoe sole repeatedly compresses and restores when worn, and the appropriate number of intake and exhaust holes are provided on both sides of the side tape portion of the stepped portion of the shoe sole. , Circulate the air inside the shoe and the fresh air outside. At the same time, the cushioning effect is exerted by the compression and restoration of the pipe, making it comfortable to wear.

[0009]

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below. First, in the insole (3) to be installed inside the shoe sole, a press board having a thickness of 3MM is used as a material for the insole (3), and the press board is cut into a foot shape, and the lower surface on the side opposite to the foot contact side is cut. A vinyl chloride pipe (4) having bending resistance is attached to the side to form a piped ventilation insole (1) having cushioning properties. The vinyl chloride pipe (4) used in the present invention has an outer diameter of 6 m.
m × 4 mm inner diameter was used.

The vinyl chloride pipe (4) is shown in FIG.
As shown in, the pitch is 8 mm from the heel to the non-step,
The non-step portion is attached at a pitch of 9 mm, and the pitch from the non-step portion to the toe portion is 10 mm at a substantially right angle to the longitudinal direction of the insole (3). In addition, a vinyl chloride pipe (4) on the insole (3)
2 to 3 as a ventilation hole (5) for circulating air inside the shoe between the pipe (4) and the pipe (4).
An appropriate number of mm holes (different between the heel portion and the tread portion) were provided.

Next, the shoe cloth (6) and the insole cloth (7) which have been cut in a separate process are sewn on the bag to form the shoe cloth (8). The shoe coat (8) was hung in a shoe mold, and a polyurethane resin as a shoe sole material was injected into a space formed by assembling a bottom mold and a horizontal mold for injection molding to form a shoe coat (8). Mold the soles together. The composition of the shoe coat (8) at this time is
It is envisaged that the ventilated insole with pipe (1) has a cavity into which it can be inserted after it has been integrally molded with the sole.

When the ventilated insole (1) with a pipe is inserted into the rising portion of the shoe sole tread formed integrally with the shoe cover (8), that is, on both sides of the side tape portion, the pipe (4) An appropriate number of intake / exhaust holes (9) having a diameter of 2,5 mm are provided at the same height position as. A ventilated shoe (2) capable of circulating warm and moist air inside the shoe and fresh and dry air outside the shoe through the intake / exhaust holes (9) to allow circulation of the intake.

Pressboard is used as the material of the insole (3) embodied in the present invention, but leather or any material having the same function as those may be used. . Further, although the vinyl chloride pipe (4) is used as the pipe (4), rubber having cushioning property, compression / restoration / bending resistance, or other material may be used.

The test method using shoes according to the present embodiment is carried out by a sensor (Separation Instrumentation Co., Ltd.) between the first and second fingers.
, Temperature / humidity sensor) was attached and walking for 1 hour. The data are shown in a graph and shown in Table 1.

[0016]

As an effect of the present invention, in spite of the simple structure in which the pipe is attached to the lower surface side of the insole, the humid action inside the shoe and the outside of the shoe are caused by the fugo action by the compression / restoration of the pipe. It is possible to constantly circulate and circulate the fresh dry air to provide sufficient ventilation. Therefore, the inside of the shoe is prevented from getting stuffy, and the generation of a bad odor is prevented, and the bad odor of the foot caused by the stuffiness and the hygienic effect such as athlete's foot are prevented.

Since the cushioning action is achieved by the compression / restoration of the pipe, it has a good cushioning property, does not hinder the impact on the instep of the foot, and can be comfortably worn even if it is used for a long time without impairing the wearing comfort. . Furthermore, because of the simple structure in which the pipe is attached to the back surface of the insole, the manufacturing is easy and the cost is low. Moreover, since it is an insole system, it can be easily replaced such as mounting and demounting.
