Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a shoe ventilation valve that is fitted into the outer circumferential surface of the sole to prevent foot swelling, and to shoes using the ventilation valve. .

[Conventional technology]

Many types of shoes have been researched and developed to prevent foot stuffiness. For example, an air pump is installed in the sole of the shoe and pressed by the sole of the foot to forcefully draw in air from outside (for example, , Jitsukai 61-
86002 (see Japanese Utility Model Publication No. 86002), and shoes having punched holes for ventilation in the upper (for example, see Japanese Utility Model Publication No. 61-5123) are known.

[The problem that the idea aims to solve]

Among the conventional techniques, the former is configured to send air from the outside of the shoe to the inside by activating an air pump that is pressed by the sole of the foot, so air is forced to be fed. However, there was a problem in that air could not be pumped in unless the air pump protruding from the sole of the foot was constantly pressed, and the user had to constantly be conscious of the feeling of pressure from the air pump protruding from the sole of the foot.

In addition, the latter has punched holes for ventilation, so air can easily escape from the inside.
On the other hand, they had the problem that moisture, mud, dust, etc. from the outside easily entered.

The present invention was developed in view of these problems with the conventional technology, and its purpose is to remove the air that produces bad odors inside shoes and causes athlete's foot, foot swelling, etc., to the outside. To provide a shoe ventilation valve and ventilation valve that can naturally discharge water, reliably block the inflow of moisture, mud, dust, etc. from the outside, and can be used in the same condition as wearing shoes normally. The present invention aims to provide shoes using valves.

[Means to solve the problem]

In order to achieve the above object, the shoe ventilation valve according to the present invention has a body body with a flange, which has a substantially cylindrical lid with a ventilation hole, and a valve support surface protruding from the inside of the lid. A spherical cap valve having a substantially spherical cap shape with a circular seat surface surrounding it is built into the inside of the valve body, and a ventilation hole is provided on the opening side of the opposite surface facing the lid of the flanged body body. and fit the flanged lid surface that covers the barrel body,
A closing edge having approximately the same diameter as the circular seat surface of the spherical valve is formed inside the flanged lid surface in the shape of a circular dam.

Furthermore, shoes using the ventilation valve of the present invention can be formed by embedding the above-mentioned ventilation valve in the peripheral side of the sole, and providing an insole inside the shoe with a bending protrusion and an air concentration outlet on the lower surface side. It is something that will be done.

(Function) The ventilation valve of the shoe configured as described above is buried at an appropriate position on the side surface around the sole of the shoe, with the lid with the ventilation holes on the outside and the lid surface on the inside, and the foot is placed inside the shoe. When the foot is placed in the shoe and the foot is moved up and down, the air inside the shoe pushes and tilts the bulbous valve outward, so there is a large gap between the closing edge provided on the circular seat surface and the flanged lid surface. 〓A gap is created, allowing the air inside the shoe to be completely exhausted.On the other hand, when water or mud enters from the outside, the crown valve is pushed inward and closes the occlusion edge, allowing water and mud to escape. In addition, by providing an air concentration outlet for the compression-type insole with bending protrusions on the inside of the position where the above-mentioned ventilation valve is attached around the sole, the insole is kept cool every time you walk. The air that has entered the bottom side is compressed, generating a compressed air jet force that is blown into the ventilation valve more strongly from the air concentration outlet, allowing the air inside the shoe to be discharged to the outside.

〔Example〕

An embodiment will be described with reference to the drawings. In FIGS. 1 to 4, the flanged body body 1 is made of plastic such as vinyl chloride resin, and has a wall thickness of about 0.5 to 1.0 mm. The front half (left side in FIG. 1) is formed into a cylindrical shape with a lid, and a joint surface 2 is provided in a diametrical direction around the other end surface side without a lid. A large number of ventilation holes 3, 3, . . . are formed in the lid portion 4 of the flanged body body 1. The valve support plate 5 is provided on the inner surface of the lid part 4 so as to protrude inward in a direction parallel to the inner circumferential surface of the flanged body body 1. The spherical crown valve 6 is formed of, for example, a rubber material into a substantially spherical crown shape large enough to fit loosely into the body of the flanged body body 1, and is loosely fitted inside the flanged body body 1 in the diametrical direction. The circular seat surface 7 is formed by slightly recessing the outer periphery of the spherical valve 6 in a circular shape.
The flanged lid surface 8 is made of plastic, for example,
It is formed into a substantially disk shape having a wall thickness of about 0.5 to 1.0 mm, and a joining surface 9 having the same diameter as the joining surface 2 is formed on the outer periphery. The ventilation holes 10, 10, . . . are formed in a checkerboard pattern in the flanged lid surface 8. The closing edge 11 is provided on the inner surface of the flanged lid surface 8 so as to protrude inward in the shape of a circular dam, and its diameter is equal to the diameter of the circular seat surface 7.
Form the same diameter as.

2 and 3, the circular seat surface 7 of the spherical valve 6 is fitted into the inside of the flanged body body 1 with the circular seat surface 7 facing away from the lid 4, and the circular seat surface 7 and the closing edge 1
When the flanged lid surface 8 is fitted to the flanged body body 1 with the valve support plates 5 and 1 facing each other, a part of the circular seat surface 7 is attached to the valve support plate 5.
The ventilation valve A is assembled by being sandwiched from the left and right sides by a portion of the closing edge 11.

In addition, in FIGS. 6 and 7, on the lower surface side of the compression type insole 12 in the shoe, approximately column-shaped as appropriate;
Bending/extending legs 13, 13... provided with a notch 14 for bending/extending.
... is provided to protrude downward, and a surrounding edge 15 is formed downward along the outer periphery of the compression type insole 12, and a part of the surrounding edge 15 is provided at a position opposite to the position where the ventilation valve A is embedded in the shoe. The air concentration outlet 16 is formed by cutting it out. In addition, when embedding the ventilation valve in the shoe, it is desirable to embed it in an appropriate position on the peripheral side of the outsole. The flanged lid surface 8 is attached to the inside of the shoe, and the ventilation holes 10 are communicated with the inside of the shoe. In addition, the crown valve 8 is the second
The upper side of the valve support plate 5 and the closing edge 11 may be held between the valve support plate 5 and the closing edge 11 as shown in FIG. The circular seat surface 7 and the closing edge 11 may be opened and closed.

[Effect of idea]

Since the present invention is configured as described above,
This produces the following effects.

Unlike conventional valves, the spherical crown valve of ventilation valve A operates with natural ventilation pressure without being forced to press or be restricted by an opening/closing shaft during opening/closing operations, so it has a simple structure. Moreover, since the air from inside the shoe is exhausted while being supported diagonally within the flange body with the valve support plate, the ventilation area is wide and the air inside the shoe can be exhausted naturally and effortlessly. On the other hand, if water or mud enters from the outside, the crown valve closes and the circular seat surface and the closing edge are sealed, completely blocking out the water and mud from the outside. Furthermore, if the ventilation valve A is used in shoes and the air concentration outlet on the surrounding edge of a compression type insole with a bending/extending leg is connected to the ventilation valve A, the air blowout effect from the compression type insole is also achieved. You can expect an even stronger air evacuation effect inside the shoe.
