Description

  The present invention relates to a ventilation function of an insole for shoes.

Traditionally, insoles made of antibacterial and deodorant materials for foot hygiene have been used, but if you walk for a long time with shoes that are easily stuffy, such as leather shoes, you sweat and become high humidity, but it is effective against high humidity. There is no. For this reason, there is an idea to give the insole a ventilation function, and there is an idea to suck air from the buttocks of the insole and exhaust it from the toe part, but to provide an air supply pipe and check valve in the insole The insole becomes thicker and the space to put your feet in is narrower, making it extremely cramped. In addition, the soles of the feet are sensitive and there is a problem of impairing walking comfort because there is a foreign body feeling when an air pipe or a reverse support valve is provided in the insole. In addition, the structure in which the air suction port is provided in the insole of the insole has a problem that the air inside the shoe is merely circulated and the outside fresh air is not taken in, so that ventilation is not achieved.
JP 7-289308 A

  When walking with leather shoes on for a long time, the inside of the shoes becomes unhygienic because it becomes highly humid due to perspiration. This invention makes it a subject to ventilate the inside of shoes with external air, without impairing the comfort of a foot | leg, when mounting | wearing with shoes and walking.

  The insole of the shoe according to the present invention is such that the top having an exhaust hole at the tip is located on the upper side, the bottom is provided with a bottom plate, and has a ventilation mechanism in the middle. A front portion is an exhaust chamber having an upward opening at a tip portion, the air chamber and the exhaust chamber communicate with each other, and a communication opening / closing valve is provided as a means for opening and closing the communication, and the rear of the air chamber A shoe insole characterized by having an intake pipe.

  When walking with the insoles of the present invention in the shoes, the air outside the shoes is inhaled and blown out into the shoes. It is not cramped and can be used comfortably because there is no air pipe or reverse valve in the part where the sole hits.

Embodiments of the present invention will be described below.
The insole body 1 of the present invention is thin as shown in FIG. 1 and has a three-layer structure as shown in FIG. 2, and the tip of the arch can be made very thin. It represents something. These three layers are composed of an upper cover 2 on the upper side, a ventilation mechanism 3 on the middle, and a bottom plate 4 on the lower side.

  FIG. 3 is a top view of the upper cover 2 and shows that an exhaust hole 12 is provided at a tip portion where a toe hits when a shoe is worn.

  FIG. 4 shows a top view of the bottom plate 4.

  FIG. 5 shows the ventilation mechanism 3. The ventilation mechanism 3 is composed of two sheets of synthetic resin film, for example, and the outer periphery is closed. If the part corresponding to the foot heel is the rear part and the part corresponding to the toe part is the front part, the air chamber 5 is provided at the rear part. There is a communication open / close valve 7 in the middle of the exhaust chamber 6, the air chamber 5 and the exhaust chamber 6, and each part communicates.

The air chamber 5 is an air pump having an intake pipe 8 at the rear and an elastic body 9 inside.

The exhaust chamber 6 has an upward opening 10 at the tip where the toes hit when wearing shoes.

  The communication on-off valve 7 is in close contact with two synthetic resin films.

  The role of the communication on-off valve 7 will be explained. Although it is difficult to peel off the two synthetic resin films that are in close contact with each other from the middle, it is difficult to peel off by the atmospheric pressure. When the air pressure in the air chamber 5 is lower than the outside air, the air chamber 5 tries to suck in air, but the two synthetic resin films of the communication opening / closing valve 7 are in close contact with each other, so that the air in the exhaust chamber 6 passes through the communication opening / closing valve 7. It is difficult. On the contrary, when the pressure in the air chamber 5 is higher than the outside air, the two synthetic resin films of the communication on-off valve 7 are peeled off, and the air in the air chamber 5 can pass through the communication on-off valve 7. It is a valve that opens and closes under the action of atmospheric pressure.

FIG. 6 shows that the elastic body 9 is placed in the air chamber 5.

  When using the present invention, the insole body 1 of the shoe is attached to the shoe as shown in FIG. FIG. 8 shows a place where air blows out from the exhaust hole 12 when a foot lands during walking, and FIG. 9 shows a place where air is sucked from the intake valve 11 when the foot leaves the ground.

  Explaining this in detail, the air chamber 5 is an air pump that uses the walking foot as a power source, and the elastic body 9 is stepped on the walking foot to perform compression and restoration. Since the air pressure is increased and decreased, when the air pressure in the air chamber 5 is increased by being stepped on, the air is not discharged from the intake valve 11 behind the air chamber 5, but becomes a blown-out pressure, and the communication opening / closing valve 7 is in close contact 2 The sheet of synthetic resin film can be peeled off from the portion connected to the air chamber 5, reaches the exhaust chamber 6, and blows out from the exhaust hole 12 through the opening 10.

  Conversely, when the foot is raised and the air pressure in the air chamber 5 is lowered, the two synthetic resin films of the communication on-off valve 7 are strongly adhered to each other by the air pressure, so that air is connected from the exhaust chamber 6 side to the communication on-off valve 7. Since it is difficult to enter the air chamber 5 through the air, the air is sucked from the intake valve 11 and can easily enter the air chamber 5.

  As described above, the communication on-off valve 7 is a valve that opens and closes by the action of atmospheric pressure. Therefore, when the top 2 and the bottom plate 4 are attached to the ventilation mechanism 3, the air chamber 5 and the exhaust chamber 6 are bonded to the top 2 and the bottom plate 4. However, the open / close valve 7 does not adhere to either.

  Since the elastic body 9 is put in the air chamber 5, in order to store as much air as possible in the air chamber 5, a sponge having an open cell structure with a high porosity is desirable, and a rigid elastic sponge having a high restoring ability is used as a material. Ideal for.

  If the overlay 2 is made of, for example, a felt plate and the exhaust hole 12 is made of, for example, a synthetic mesh mesh cloth, the feeling during use can be improved. The bottom plate 4 is made of, for example, a plate using a synthetic resin.

  FIG. 10 shows a top perspective view of the intake valve 11. The intake valve 11 has a circular or elliptical intake port, and a back cover 13 is provided inside the intake port. The back cover 13 is made of, for example, a synthetic resin film larger than the air inlet, and a part of the back cover 13 is bonded and fixed to the side of the air inlet so that it can be opened and closed. FIG. 11 is a cross-sectional view of the intake valve, which shows that the back cover 13 opens and sucks air as shown by an arrow.

As described above, when walking with the insole of the shoe of the present invention, the air outside the shoe is inhaled and the air is blown out from the vicinity of the toes, so that the inside of the shoe can be ventilated, and the air pipe or Since the reverse valve is not used, the foot does not feel foreign and comfort is not impaired.
