Further, the pump 3 comprises an air ventilating pipe 7 which is connected to the exhaust non- return valve 6 and has a vent hole 8 disposed in such a manner as to turn upward in a part of the shoe sole 1 and an inner sole of a shoe that corresponds to near the root of foot fingers.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sole plate used for shoes, boots, slippers and the like.

[0002]

2. Description of the Related Art Conventionally, bottom plates used for shoes, boots, slippers and the like include an insole which absorbs a bad odor caused by stuffiness of a foot, an insole made of a breathable material and the like. However, there was no sole or insole having a ventilation mechanism for exchanging the atmosphere near the base of the toes, which has particularly bad ventilation, with fresh air.

[0003]

Generally, when shoes, boots, etc. are worn for a long period of time, the feet pass through the socks almost in close contact with the space formed by the instep and bottom plate of the shoes, boots, etc., which are not breathable. Is cut off from the outside air, so it is exposed to a hot and humid atmosphere,
It causes unpleasant foot stuffiness. In addition, when it is affected by bacteria etc. in that state, it may suffer from diseases such as athlete's foot. However, for that reason, it is unavoidable to wear shoes, boots, etc., and the cause of athlete's foot is unavoidable every day. As described above, the conventional technique has a problem that it lacks breathability in consideration of foot hygiene. SUMMARY OF THE INVENTION Therefore, an object of the present invention is to eliminate such drawbacks of the prior art as much as possible, and to provide a shoe sole and an insole with good air permeability that can be used for shoes, boots and the like.

[0004]

According to the present invention, a pump chamber is provided at a portion corresponding to the sole of a shoe, boots, etc., and the heel of a foot of an insole, and air in the pump chamber is passed through a ventilation pipe. It is provided with a vent for sending the air to the tip of the foot and ejecting the air toward the vicinity of the base of the toe.

[0005]

According to the present invention, fresh air sucked into the pump chamber of the sole of the shoe, boots, etc. and the heel of the insole is sent to the part corresponding to the tip of the foot through the ventilation pipe, and the root of the toe. Gush toward the neighborhood. As a result, the hot and humid atmosphere near the base of the toe, which has the poorest air permeability in the past, is forcibly replaced with fresh air.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A shoe sole and an insole according to the present invention will now be described by way of embodiments with reference to the accompanying drawings. FIG. 1 is a partial vertical sectional view of a shoe using a shoe sole according to the present invention. A pump 3 is provided inside the portion of the sole 1 corresponding to the heel of the foot.
The pump 3 is made of, for example, an elastic member such as rubber, and has a structure that expands in a free state and contracts in a compressed state. The pump 3 has an intake check valve 4 and an exhaust check valve 6
It has. The intake check valve 4 communicates with the outside air via an intake pipe 5, and is arranged to suck the outside air into the pump 3. The exhaust check valve 6 is arranged so as to discharge the air sucked into the pump 3. A ventilation pipe 7 is connected to the outside of the exhaust check valve 6 and is provided in a portion corresponding to the toes through the inside of the shoe sole. The ventilation pipe 7 has a configuration in which a ventilation port 8 is arranged upward at a position corresponding to the vicinity of the base of the toes of the shoe sole. FIG. 2 is a plan view of the shoe sole and insole of FIG. Since the shoe sole 1 and the shoe insole 2 have the same structure, they are both described in FIG. Air sucked from the intake check valve 4 through the intake pipe 5 enters the pump 3, passes through the exhaust check valve 6 and the ventilation pipe 7, and is ejected from the ventilation port 8 to the upper surface of the shoe sole. ing. It is assumed that a shoe having a shoe sole having such a configuration, or a shoe with an insole having such a configuration is put on and walking. When the heel of the foot is stopped by stopping or standing upright, the pump 3 is compressed by the heel of the foot and contracts. When the foot is stepped on, the heel of the foot rises, so that the pump 3 made of an elastic member expands and sucks air from the check valve 4 for intake through the intake pipe 5. When the heel of the foot is attached again, the pump 3 is contracted, and the air taken into the pump 3 passes through the exhaust check valve 6 and is discharged to the ventilation pipe 7. The air discharged to the ventilation pipe 7 is ejected from the ventilation port 8 onto the upper surface of the shoe sole. That is, every time one step is walked, the pump 3 operates and air is ejected from the vent through the vent pipe 7. Therefore, by walking or by moving the heel of the foot up and down, a fixed amount of air is intermittently ejected from the ventilation port 8. Because of this air, the air near the toes, especially near the base of the toes, is forcibly replaced with fresh air. Therefore, there is an effect of preventing the air around the root from becoming hot and humid. When the shoe sole according to the present invention is used for deep boots or boots, it is preferable that the intake pipe 5 is extended and fixed to the inner upper part of the shoe in order to inhale fresh air.
Depending on the mounting position of the intake pipe 5, the mounting position of the intake check valve on the pump may be changed. The exhaust check valve 6 may be omitted depending on the type of the intake check valve 4. Further, the configuration according to the present invention can be applied to a slipper or the like. It is possible to forcibly inhale the cleaning agent or the like using the intake pipe 5.

[0007]

As described above, according to the present invention, by simply walking, it is possible to forcibly supply fresh air, a cleaning agent, or the like to the toes, particularly near the base of the toes, where steam easily occurs. Effective for health and hygiene. As a result, it is effective in preventing diseases such as athlete's foot.
