Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a shoe sole having excellent breathability and a shoe using the sole.

[0002]

[Prior art]

 There are various types of shoes, such as cloth shoes, leather shoes using natural leather or synthetic leather, and in all cases, the air permeability is generally poor. Therefore, there is a troublesome problem that footsteps and unpleasant odors are generated particularly in summer. Therefore, in order to improve air permeability, measures such as making the upper part of the shoe a mesh or providing fine holes have been taken. As another method, a sheet material with good air permeability is laid inside the shoe (insole). In addition, there were shoes with vent holes formed on the bottom or side of the sole.

[0003]

[Problems to be solved by the invention]

 However, it is hard to say that any of the conventional measures has sufficient air permeability. Shoes with mesh or fine holes on the upper side of the shoe certainly improve the air permeability of the upper and side of the foot, but do not improve the air permeability of the sole. There is also a problem that dust enters the shoe through meshes and fine holes, and when it enters a rainy day or a puddle, water enters the shoe. In addition, the measures to spread a sheet material with good air permeability inside the shoes alone can slightly improve the feel of the sole portion, but hardly improve the air permeability of the entire foot. Further, in the case of simply providing a ventilation hole on the lower surface or the side surface of the shoe sole, if the hole is too small, air permeability will be poor, and if the hole is too large, water or dust may enter from the outside. Therefore, the present invention has an object to solve such a problem, and an object of the invention is to provide a shoe sole for that purpose and a shoe using the shoe sole, which has good air permeability and does not allow water or dust to enter from the outside. Things.

[0004]

Means for Solving the Problems A shoe sole according to the present invention that solves the above-mentioned problems has a plurality of ventilation grooves provided on the upper surface, an air chamber communicating with the ventilation grooves in the heel portion, and a communication with the ventilation grooves. The sole is provided with a vent hole 6 opened to the outside side surface and a check valve type air valve provided in the vent hole to suppress the ventilation from the outside to the inside (claim 1). By joining an insole having a large number of through holes on the sole of the shoe and joining it to the upper part, a shoe with good air permeability can be manufactured. That is, the outside air enters the inside of the shoe from around the foot, passes through the through hole of the insole, and is discharged to the outside through the ventilation hole through the ventilation groove, so that high ventilation can be obtained throughout the foot. . However, the provision of the check valve type air valve can effectively prevent dust and moisture entering from being accompanied by ventilation from the outside to the ventilation hole.

In the shoe sole, the ventilation groove can be formed in a mesh shape. Thereby, air permeability can be further improved. In the above shoe sole, the air valve includes a cylindrical valve body, a closing valve seat provided on the ventilation groove side in the inside thereof, and an opening valve seat provided on the opening side. And a valve portion movable between the portions (claim 3). Further, in the above-mentioned shoe sole, the valve body has a side lid portion provided at one end portion, a cylindrical first member having a number of small holes penetrating the side lid portion, and a valve body inserted at the other end portion. A first member having a plurality of convex portions provided on an inner peripheral surface thereof to constitute the opening valve seat portion, and an annular surface formed on one end surface of the second member. A closing valve seat portion, wherein the valve portion has a diameter such that a ventilation portion is formed between the valve member and the inner periphery of the first member, and has a diameter smaller than the inner diameter of the closing valve seat portion; It can be made of a rubber material or a synthetic resin material having a large flat circular shape (claim 4).

Next, a shoe according to the present invention that solves the above-mentioned problem includes the above-mentioned sole, an insole arranged on the sole, and an upper part, and the insole is provided with a large number of through holes. (Claim 5). The shoe configured in this way has excellent air permeability as described above. In the above shoe, the through hole of the insole can be provided by punching (claim 6), and by using such an insole, the manufacturing cost of the shoe can be reduced.

[0007]

[Embodiment of the invention]

 Next, an embodiment of the present invention will be described with reference to the drawings. FIG. 1 is an exploded perspective view showing an example of a shoe having a shoe sole according to the present invention. FIG. 2 is a cross-sectional view taken along the line II-II of FIG. 1 and shows an internal air outflow state. FIG. 3 is an explanatory view showing the operation when air flows backward, and FIG. 4 is a partially cutaway perspective view of the air valve. The sole 1 is made of, for example, synthetic rubber or leather integrally or laminated, and has a front part 2 and a rear part 3. The front 2 supports from the tip of the foot to the arch, and the rear 3 supports the heel of the foot. A mesh-shaped ventilation groove 4 is provided on the upper surface of the front part 2, and a large number of ventilation grooves 4 are also provided on the upper surface of the rear part 3 vertically and horizontally. The lateral ventilation groove of the rear part 3 is an air chamber 16 that is deeply recessed. The ventilation grooves 4 of the front part 2 and the rear part 3 communicate with each other. Further, a ventilation hole 6 is provided in the side portion 5 of the rear portion 3, and the ventilation hole 6 communicates with the air chamber 16 and the ventilation groove 4 of the rear portion 3.

A check valve type air valve 7 shown in FIGS. 2 to 4 is mounted in the vent hole 6. The air valve 7 includes a valve body 8 made of plastic and a valve portion 10 made of rubber or synthetic rubber. The valve section 10 is a type of check valve. That is, air is circulated only from the inside to the outside of the shoe, preventing the backflow and preventing the outside water and dust from entering the shoe. The valve body 8 of this example includes a cylindrical first member 8a having a large number of small holes 12 penetrated in a side lid portion 11 and a short cylindrical second member 8b as shown in the figure. The first member 8a has a flange body 9 provided on the outer periphery of one end of the side lid portion 11, and the other end is formed in a truncated cone shape. A plurality of convex portions 15 are formed integrally on the inner peripheral surface in the axial direction, and the rear end surface constitutes the valve seat 14 for opening. The outer periphery of one end of the second member 8b is aligned with the inner periphery of the first member 8a, the outer periphery of the other end is formed in a truncated cone shape, and the outer surface thereof is aligned with that of the first member 8a. On one end surface of the second member 8b, an inner flange-shaped closing valve seat portion 13 is formed.

In a state where the second member 8b is pressed into the other end of the first member 8a, the valve portion 10 is provided between the opening valve seat portion 14 and the closing valve seat portion 13 in the axial direction. It is stored slightly movably. The valve section 10 is formed to have a diameter such that a ventilation section is formed between the valve section 10 and the inner periphery of the first member 8a, and has a plane circular shape larger than the inner diameter of the closing valve seat section 13. It is made of rubber or synthetic rubber or other elastic material with a guiding spherical part at the center. This check valve structure may employ another known check valve.

Next, the ventilation action of the sole 1 shown in FIG. 1 will be described. The ventilation 17 from the upper part of the sole 1 is formed by the ventilation groove 4 of the front part 2 and the ventilation groove 4 of the rear part 3 as indicated by arrows. Then, the air flows into the air chamber 16, enters the air valve 7 from there, moves the valve unit 10 to the left, and presses it against the opening valve seat 14. Then, the ventilation 17 is discharged to the outside through the small hole 12 from the gap between the outer periphery of the valve portion 10 and the inner periphery of the first member 8a. Conversely, ventilation from the outside causes the valve portion 10 to be pressed against the closing valve seat 13 as shown in FIG. As a result, it is possible to effectively prevent moisture from entering the inside of the shoe sole together with ventilation from the outside on the outside dust or on a rainy day. In some cases, the air valve 7 may be omitted. In this case, due to the flow resistance of the small holes 12, the ventilation from the outside is suppressed to the same extent as the exhaust from the inside.

As shown in FIG. 1, a shoe 20 manufactured using the sole 1 includes an insole 21 and an upper portion 22 disposed on the sole 1, and the insole 21 has a punching surface. A large number of processed through holes 23 are provided. The shoe 20 is manufactured by integrating the shoe sole 1 and the upper part 22 through an insole 21 by bonding or the like. With the foot inserted into the shoe 20, the ventilation 17 from the underbody passes through the through hole 23 of the insole 21 from the upper part 22 as shown by the arrow, and then through the ventilation groove 4 of the shoe sole 1. Is discharged outside from the air valve 7.
