DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a breathable shoe sole and a breathable shoe. More specifically, the present invention relates to a breathable shoe sole for improving breathability in a shoe and a breathable shoe sole using the breathable shoe sole.

[0002]

2. Description of the Related Art Hitherto, so-called shoes having an upper such as leather shoes and sports shoes have a poor air permeability because they have a structure in which the entire foot is covered. For this reason, wearing shoes for a long time becomes humid, causing athlete's foot or the like, or causing odor.

[0003] In order to solve these drawbacks, many shoes have been proposed to improve the air permeability in the shoes, for example, shoes having a large number of holes in the upper, and shoes for sending air into the shoes. I have.

[0004] However, shoes having a large number of holes in the upper cover are based on natural ventilation, and cannot provide a sufficient effect.

[0005] Also, shoes in which air is blown into the shoes are disclosed in, for example, Japanese Utility Model Laid-Open No. 61-43402 and Japanese Unexamined Patent Publication No.
In these shoes, a pump chamber is provided in the heel portion of the shoe sole, and a ventilation path for sending air from the pump chamber to the toe portion is provided in the shoe sole. Provided. In these shoes, air is forcibly sent from the pump chamber provided in the heel into the inside of the shoes, and the air permeability is improved.

However, in order to improve air permeability, it is preferable to send air to the toe. However, since the pump chamber is provided in the heel, an air passage for sending air to the toe is provided in the sole of the shoe. It had to be provided and was structurally complicated.

[0007] When the heel part touches the ground, air is sent from the pump chamber into the shoe. At this time, the pump chamber in the heel part may serve as a cushion, making it difficult to walk. . In particular, if the capacity of the pump chamber is to be increased, the amount of change in the heel must be increased, which has also caused difficulty in walking.

[0008]

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned drawbacks of the prior art, and provides a shoe having a relatively simple structure and excellent breathability, which is easy to walk. It is in.

A breathable shoe A shown in FIG. 1 includes a breathable shoe sole 100 according to the present invention and an upper 200. The material of the upper 200 is not particularly limited as long as it is used for ordinary shoes, and real leather or synthetic leather can be used.

Further, the breathable shoe sole 100 according to the present invention comprises:
Ground bottom 110, underlay plate 120, insole plate 130, overlay plate 140, coiled spring 150, and frame 1
The pump chamber 180 is provided between the grounding sole 110 and the overlay 140 at the front of the breathable shoe sole 100.

The grounding sole 110 is a portion that comes into contact with the ground or the like during walking, and more specifically, corresponds to a front part of the sole of the foot, more specifically, a toe part 111 corresponding from the toe to the arch of the sole and a heel. The heel portion 112 is integrally formed from, for example, real leather, synthetic leather, rubber, urethane, or the like. In addition, in this invention, "front part" shall show the area | region corresponding from a toe except a heel to an arch.

The underlaying plate 1 is provided around the grounding bottom 110.
20, insole board 130, overlay board 140, spring 150
Is provided. The frame part 160
Is for forming a pump chamber 180 at the front of the shoe sole 100 as described later, and mainly constitutes a side wall portion of the pump chamber 180. Therefore, at least the pump chamber 18
The side wall portion 0 needs to have flexibility enough to follow a change in volume of the pump chamber 180, and is made of, for example, rubber or urethane. At this time, by using rubber or urethane, it can be integrally formed with the grounding bottom 110. Of course, it is conceivable that the frame 160 is provided only in the region constituting the side wall of the pump chamber 180.
The airtightness can be further improved, and the appearance of the shoe sole 100 can be improved.

The underlaying plate 120 is used to prevent the spring 150 from being displaced.
0 is provided corresponding to the toe portion 111. In the present embodiment, it is provided corresponding to the entire surface of grounding bottom 110. The base plate 120 is made of, for example, urethane, rubber, paper, or the like, and a plurality of holes 121 or recesses for fitting the lower ends of the springs 150 are formed in a region where the pump chamber 180 is formed. The underlay plate 120 is attached to the upper surface of the ground bottom 110.

The spring 150 is provided between the ground floor 110 and the overlay 140, and supports a front portion of the overlay 140, that is, a region corresponding to the toe portion 111 of the ground floor 110 above the ground floor 110. So that the pump chamber 180 is located between the ground bottom 110 and the overlay 140.
Is formed. The spring 150 has such a strength that it is not sufficiently compressed in a natural state of wearing shoes, and is sufficiently compressed in a state where weight is added to a toe during walking. It has elastic force. Of course, it may be compressed to some extent in a natural state, and in this case, an appropriate cushioning property can be given. The lower end of the spring 150 is fitted into the hole 121 of the underlay plate 120, and is disposed on the ground bottom 110.

The insole board 130 includes the grounding bottom 110 and the oversole board 1.
40, and supports the rear portion of the overlay 140, that is, the area corresponding to the heel portion 112 of the ground contact sole 110. The insole plate 130 is also made of, for example, rubber or urethane,
Although it is made of paper or the like, it is preferable to use rubber or urethane having a relatively large elastic force from the viewpoint of absorbing the impact given to the heel. At this time, if the elastic force of the insole plate 130 is too large, the heel portion 112 will sink too much during walking, and the front of the sole 100 supported by the spring 150 may be lifted.
It is appropriately selected according to the strength of 0 and the desired cushioning property of the heel portion 112.

The upper board 140 is an insole 21 in contact with the sole of the foot.
This is a part that is bonded to the bottom of the pump chamber 180, and forms the upper wall of the pump chamber 180 and supports the toe.
The overlay 140 is made of, for example, cardboard and has a size corresponding to the entire sole of the foot, but has sufficient strength to support the toes and not transmit the feel of the spring 150 disposed on the lower surface. (Thickness). Also,
A large number of ventilation holes 141 are opened at the front of the overlay 140.

On the lower surface of the overlay 140, a columnar support 155 for supporting the upper end of the spring 150 is provided. The material of the support portion 155 is not particularly limited, but is preferably a lightweight material. For example, the support portion 155 may be made of metal such as aluminum, plastic, or the like.
0, and is made of a size that can be inserted into the inside of
Is bonded to the lower surface. Of course, it may be made integrally with the overlay 140 from paper or the like.

These components are assembled as follows. First, an underlaying plate 120 is laid on the upper surface of the grounding bottom 110 and bonded with an adhesive or the like. Next, the insole board 130 is attached to the heel portion 112 of the underlay board 120 at a predetermined position.
In addition, at the front part of the grounding bottom 110 forming the pump chamber 180, the lower end of the spring 150 is crimped into the hole 121 of the underlay plate 120, and the spring 150 is arranged. After that, the support portion 155 on the lower surface of the overlay 140 is crimped inside the upper end of the spring 150 and attached to the upper surface of the insole 130. After that, the upper end of the frame 160 is folded inward and bonded to the upper surface of the overlay 140. Thus, the breathable shoe sole 100 according to the present invention in which the pump chamber 180 is formed in front of the shoe sole 100 can be manufactured. Further, the upper 200 provided with the insole 210 is bonded to the shoe sole 100, whereby the breathable shoe A according to the present invention can be manufactured. Note that the insole 210 is also provided with a vent hole 211 corresponding to the opening position of the vent hole 141 of the overlay plate 140.

In the breathable shoe A, when walking, the weight is applied to the toes, and the spring 150 is compressed. As a result, the volume of the pump chamber 180 is reduced, and air is discharged from the ventilation holes 141 and 211 into the inside of the shoe. Also, when the toes separate from the ground, the spring 15
Due to the zero elastic force, the volume of the pump chamber 180 returns to its original state.
Thus, during walking, the volume of the pump chamber 180 changes, and air is sent into the shoe.

In particular, the pump chamber 180 is provided with the breathable shoe sole 1.
Since it is provided at the front part of 00, a large sole area can be obtained, and the ventilation volume can be increased without increasing the thickness of the shoe sole. In addition, the ventilation holes 141 and 211 can be easily opened in a relatively large portion of the sole of the foot, and air can be sent to the entire front part of the sole with a simple structure as compared with the case where the ventilation path is provided from the heel. Further, the heel portion 112 is not elastically deformed at the time of touching the ground, so that a firm foot can be felt at the time of touching the ground, and the difficulty of walking can be reduced.

In the present invention, various embodiments are conceivable. In the breathable shoe B shown in FIG. 5, the support 151 is provided on the upper surface of the grounding sole 110, and the support 151 is inserted into the lower end of the spring 150 to prevent the spring 150 from being displaced. Can be. As described above, the support portion 151 may be made of metal such as aluminum, plastic, or the like, and may be attached, or may be integrally formed with the grounding bottom 110. Further, the insole plate 130 is formed integrally with the grounding bottom 110. As described above, by integrally molding the support portion 151 with the grounding bottom 110 or integrally molding the grounding bottom 110 and the insole plate 130, the number of components can be reduced and the manufacturing process can be simplified.

Further, in the manufacturing process, it is usual that the insole 210 is bonded to the upper 200 in advance, and then the upper 200 is bonded to the shoe sole 100. The overlay plate 140 also has the function of the insole 210, and the overlay plate 140 in which the ventilation holes 141 are opened.
May be directly bonded to the upper surface of the ground bottom 110, and the front of the overlay 140 may be supported by the spring 150. With such a configuration, the insole 2
10 is not required, the number of parts can be reduced, and the manufacturing process can be simplified.

In the present invention, the spring 15
The elastic deformation of the pump chamber 180 causes the volume change of the pump chamber 180, and various elastic bodies such as a leaf spring and rubber may be used in addition to the coiled spring as long as the function is achieved. It goes without saying that you can do it.

Further, in the breathable shoe C shown in FIG. 6, an upper 200 having a large number of holes 220 is provided in the upper part. By using the upper 200 having the holes 220 or the upper having a mesh structure, a breathable shoe with higher air permeability can be provided.

Next, a breathable shoe D shown in FIG. 7 includes a breathable shoe sole 300 and an upper cover 200 according to still another embodiment of the present invention. In this case, a concave portion 181 is formed in front of the thick grounding bottom 110, and the underlay plate 120, the insole plate 130, and the frame portion 1 are formed.
60 is configured integrally with the ground bottom 110. Further, a plurality of recesses 121 for fitting the lower ends of the springs 150 are formed on the bottom surface of the recess 181. In the breathable shoe D, a plurality of springs 150 are arranged in the shoe width direction, and the springs 150 are arranged in a plurality of rows.

Further, a plate 190 is provided on the lower surface of the overlay 140 so as to be located between the overlay 140 and the spring 150. The plate-like body 190 is for preventing bending of the overlay 140 and is used to reinforce the strength of the overlay 140. The above breathable shoes A to C
In the above, the moisture such as perspiration from the soles during use is absorbed by the overlay 140, and depending on the material of the overlay 140, the strength of the overlay 140 decreases, and the pump chamber 1
80 may not be able to produce a sufficient volume change. For this reason, the plate-shaped body 190 is preferably made of a material having a strength enough to achieve the object. For example, a thin metal plate, particularly made of aluminum or stainless steel to reduce the weight, is used. The plate 190 or the like is selected.

In order to achieve the above object, it is preferable that the plate 190 is provided on the entire surface of the area where the pump chamber 180 is formed. However, in order to further reduce the weight of the breathable shoe sole 300, the plate 190 is formed. Is preferably provided partially. For example,
In the breathable shoe sole 300, a rectangular plate-like body 1 formed in a size such that upper end surfaces of a plurality of springs 150 provided in the width direction of the breathable shoe sole 300 are connected.
90 are provided substantially in parallel. Further, the plate-like body 190 only needs to be capable of causing a sufficient volume change in the pump chamber 180 even when the strength of the overlay plate 140 itself is reduced. For example, the plate-like body 190 has substantially the same size as the upper end surface of each spring 150. The plate 190 may be provided at the upper end surface of each spring 150.

It is preferable that the plate 190 is bonded to the lower surface of the overlay 140. When the plate 190 is bonded to the overlay 140 in this way, the plate 190 does not displace from the upper end surface of the spring 150, and the ventilation holes 141 opened in the overlay 140 are formed.
Is not blocked. In the breathable shoe sole 300, as shown in FIG. 11, a ventilation hole 141 is formed in a region where the plate-like body 190 is not provided.
Of course, it is conceivable that the ventilation holes 141 are also formed in the plate 190 so as to match the ventilation holes 141 formed in the overlay 140.

Further, in the case of the breathable shoes D, the upper board 1
The foot sole 400 is provided on the upper surface of the forty. The footbed 4
00 is provided with a large number of convex bodies 420 for forming a gap between the sole plate and the sole on the thin plate-like support plate 410,
Breathability of the sole is ensured. The convex body 420 only needs to be able to form a gap between the sole and the sole, and the shape, size, number, etc. of the convex body 420 are not limited. For example, a conical shape or a hemispherical shape with a rounded tip portion And so on. At this time, as shown in FIGS. 8 and 9, a conical convex body 420 having a rounded tip is provided, and the convex
By appropriately changing the height so that the tip of 0 is in contact with the sole of the foot, a shiatsu effect can be given during walking.

The support plate 410 has a large number of air holes 43.
0, at least a part of which is
It is opened so as to substantially coincide with the ventilation hole 141 opened at 40. By providing such a foot sole 400, the air permeability of the sole is ensured, and the stuffiness of the foot can be further prevented.

The upper 200 is provided with a large number of holes 220 on at least the side surfaces thereof, particularly in a region corresponding to the arch. By forming a hole in the side surface of the instep, the air sent from the pump chamber 180 can easily go out, and the air permeability can be further improved. In particular, the region corresponding to the arch is more effective because the instep is bent during walking and a large gap is formed between the foot and the instep.

Of course, as in the case of the breathable shoe E shown in FIG.
By using the upper having a mesh structure or a mesh structure, a breathable shoe having higher breathability can be provided.

[0038]

According to the present invention, there is provided a breathable shoe sole comprising at least a grounding sole, an overlay having a vent hole, and an elastic body supporting the overlay on the grounding sole. A bottom, provided between the grounding bottom and the overlay;
Since the pump chamber whose volume can be changed by the elastic deformation of the elastic body is formed at the front of the breathable shoe sole, the pump chamber can be provided with a relatively simple configuration, and it is possible to provide the pump chamber during walking. Air can be sent into the shoes.

Since the pump chamber is formed at the front of the shoe sole, the pump chamber can be formed entirely forward of the heel. Therefore, a pump chamber having a large volume can be formed with the height of the shoe sole being relatively low, and the ventilation volume can be increased.

Further, during walking, the heel portion is not affected by the elastic deformation of the pump chamber, and the difficulty in walking can be improved as compared with the case where the pump chamber is provided in the heel portion.

At this time, if a plate-like body is provided between the overlay and the elastic body, the strength of the overlay can be increased, and the flexure of the overlay due to moisture or the like during use can be prevented.
A sufficient change in the volume of the pump chamber can be ensured.

If the plate is attached to the lower surface of the overlay, the displacement of the plate during use can be prevented. As a result, the plate-like body can be partially provided corresponding to the upper end surface of the elastic body without providing the plate-like body over the entire area corresponding to the pump chamber, and the weight of the breathable shoe sole can be reduced.

As described above, according to the present invention, a breathable shoe which is easy to walk and has excellent breathability can be provided with a relatively simple structure.

Further, a gap is formed on the upper surface of the breathable shoe sole between the sole plate and a support plate having another ventilation hole at substantially the same position as the hole position of the ventilation hole formed in the overlay. By providing the foot sole having a large number of convex bodies for the airflow, the air permeability can be further secured.
