Description

Detailed Description of the Invention

The present invention is a compression mechanism that automatically operates fresh air filtered through an ultrafine filter inside a shoe, particularly a fingertip portion, by the pressure between the heel by weight and the insole of the shoe during walking or running. The present invention relates to a device for supplying air to a portion to prevent stuffiness inside the shoe.

  Conventional shoes that are woven with a net-like (commonly known as mesh) leather for ventilation and those with a hole for ventilation near the tip are on sale. Forcibly, shoes with a mechanism for ventilating the air inside the shoes are not sold on the market.

Problems to be solved by the invention

A filter using micro technology is attached to an air filtering device for supplying fresh air to the inside of the shoe, particularly the tip portion. This filter is an ultra-thin tube filter that allows only air to pass through and does not allow moisture and germs to pass through it. It can be manufactured in any shape and can be processed according to the shape of the air intake.
A reversely supported valve type air compression mechanism that sends out air has a simple structure, a light weight, a thin and excellent durability and a ventilation function.
Supplying shoes equipped with these functions to the market at a low price is also a problem to be solved by the present invention.

Means for solving the problem

  The present invention is a mechanism that solves all of the above-mentioned conditions. An air compression device that is attached to the insole of a shoe will be described. The thickness of the compression mechanism main body is 2 to 3 millimeters, and the back support valves are respectively provided on the intake side and the exhaust side. It has a simple structure with a weight of about several grams and a highly durable material and shape, and does not feel any sense of incongruity to the heel of a foot even when walking or running with shoes on.

The filtration device that supplies fresh air to the reversely supported valve type air compression mechanism is equipped with an ultra-fine filter that applies micro technology. This filter is an ultra-thin tube filter that allows only air to pass through and does not allow moisture and bacteria to pass through. It reduces the humidity inside the shoe and prevents the growth of bacteria, which also prevents the generation of off-flavors caused by foot stuffiness. I can do it.
The shape of the filter can be made in any shape and can be processed according to the shape of the air intake.
The intake of fresh air into the shoe interior of the present invention is taken from the side of the arch of both feet, and the ultrafine filter is processed into a thin shape and attached to the inside of the shoe.

  A pipe for supplying fresh air to the tip inside the shoe is arranged at the side bottom of the shoe sole. With regard to the air supply amount, the space at the tip is 10 to 50 cubic centimeters with the shoes on, so that the volume delivered by one step of pressure is enough to be several mm cubic. Since ordinary pedometers are about 80 to 160 steps per minute, assuming that the average is 100 steps, if there is a sending ability of only 5 mm cubes with a pressure of one step, the replacement of air in a space of 50 cubic centimeters, Theoretically, it can be done in just one minute. However, when the shoe tip is in a closed room due to socks to protect the foot, the toe portion inside the shoe is in a pressurized state. However, in daily life walking thousands of steps a day, it is practically possible.

The ventilating mechanism inside the shoe of the present invention includes an air filtration device for inhaling air in the insole of the shoe, a so-called diaphragm pump having a check valve, an air pipe for sending fresh air to the tip portion inside the shoe, etc. Keep all the sets.
The shoe manufacturer prepares in-house ventilators of various sizes according to the size of the shoe so that it can be set in the same process as the middle type.

The ultrafine filter of the ventilation mechanism inside the shoe of the present invention will be described. This filter is made of a material commonly called a micro filter. The product name is “Gore-Tex”, a microfiber that is often used in sportswear and sports equipment. It has the property of allowing only air to pass through but not allowing water vapor or bacteria to pass through.
Using this as a material, it is used by sticking it on the side of the arch inside the shoe by finishing it thin. As for the intake air, the amount of permeation is about 50 cubic centimeters per minute. Therefore, for intake of outside air, a sufficient amount of outside air can be taken in by opening 3 to 5 intake ports with a diameter of about 1 mm on the upper side of the filter. I can do it.
The taken-in air is connected to the input side counter-support valve of the counter-support valve type air compression mechanism with a pipe having a diameter of about 1 mm from the bottom of the filter.

The reversely supported valve type air compression mechanism of the present invention will be described. This is a so-called diaphragm pump. The thickness is about 3 millimeters and it is attached to the back of the heel part of the insole. Fresh air delivered from the filter is taken into the main body of the compression mechanism through the check valve from the air intake port, and when the upper surface of the compression mechanism is pushed down by repeated actions of walking or running, the reverse The branch valve 1 is closed and the reverse branch valve 2 is opened, so that the air inside the compression mechanism can be supplied to the fingertip partial air inside the shoe by a pipe connected to the reverse branch valve 2.
In addition, when the kite moves away from the insole due to walking or running, the upper part of the compression mechanism tries to return to the original state, and the internal pressure becomes negative pressure, so the reverse support valve 2 is closed and the reverse support valve 1 is opened. Fresh air from the inside fills the compression mechanism.
By repeating this operation, fresh air can be continuously sent to the fingertip portion inside the shoe during walking or running.
The air pipe delivered from the compression mechanism is a thin pipe with a diameter of about 1 mm and is piped along the side of the insole, so there is no sense of incongruity about the foot inside the shoe.

  A reversely supported valve type air compression mechanism using the cavity inside the bag according to the present invention will be described. In order to reduce the weight of the shoe, a reverse valve type air compression mechanism (commonly referred to as a diaphragm pump) is attached by applying a cavity provided inside the bag. Fresh air delivered from the filter is taken into the main body of the compression mechanism through the check valve from the air intake port, and when the upper surface of the compression mechanism is pushed down by repeated actions of walking or running, the reverse The branch valve 1 is closed and the reverse branch valve 2 is opened, so that the air inside the compression mechanism can be supplied to the fingertip partial air inside the shoe through a pipe connected to the reverse branch valve 2.

The invention's effect

In this way, when walking or running with a shoe equipped with the “ventilation mechanism inside the shoe” of the present invention, fresh air passes through the filter due to repeated movement of the heel during walking or running. After passing through the compression mechanism, the shoe is continuously supplied to the fingertip portion inside the shoe, and the air inside is automatically circulated and pushed out, so that the inside of the shoe is constantly replaced with fresh air.
Especially for shoes with extremely poor air intake, such as the so-called “boots” worn by women, it is possible to continually incorporate fresh air into the entire shoe by attaching an air intake filter to the top of the boot. Can walk comfortably.
As described above, the present invention eliminates moisture at the fingertips inside the shoe, and can replace the fresh air to contribute to maintaining the health of the foot without causing stuffiness or an unpleasant odor. I am sure.
