Description

[Detailed Description of the Invention] <Industrial Field of Application> This invention relates to footwear having a plurality of ventilation holes in the sole plate in order to significantly improve ventilation when worn.

<Prior art> For example, footwear with multiple holes in the sole plate was developed by Jikosho.
It is known from Japanese Utility Model Publication No. 55-31921, Japanese Utility Model Publication No. 55-40005, Japanese Utility Model Publication No. 116504/1983, Publication of Japanese Utility Model Publication No. 178104/1988, etc.

The footwear described in each of the above-mentioned publications has a horizontally elongated hole or a hollow part formed inside the sole plate, and this horizontally long hole or hollow part is communicated with the upper surface of the sole plate through a small hole opened in the vertical direction.

<Problems to be Solved by the Invention> However, in the above-described configuration, since the horizontally elongated holes and voids exist in the width direction of the bottom plate, outside air does not pass through and are not guided to the top surface of the bottom plate.

In addition, since the small holes are perpendicular to the horizontally long holes and the voids, there is a large resistance to the passage of outside air from the horizontally long holes to the small holes, which prevents outside air from flowing into the inside of the footwear. I can't expect much. In addition, since sand and dust tend to accumulate in the horizontally elongated holes and empty spaces in the width direction, these holes and empty spaces may become clogged and the air permeability may be lost.

<Means for Solving the Problems> The present invention has been proposed in view of the above, and is a footwear having a bottom plate in which at least an upper plate and a lower plate are bonded together, wherein the upper plate of the two plates is There are multiple holes penetrating through the thickness of the bottom plate, and the upper surface of the lower plate has a
The base end communicates with the above-mentioned through hole and the distal end opens to the side edge of the lower plate, and a groove is formed where the distal end is deeper than the base end. It is characterized by communicating with the side surface of the bottom plate via a ventilation hole constituted by a hole and a groove,
For example, it can be effectively used for various sports shoes, sandals, etc.

<Examples> The present invention will be described below with reference to embodiments shown in the drawings.

The drawing shows only the sole plate 1 of the footwear, and the sole plate 1 includes at least an upper plate 2 and a lower plate 3.
It is made by pasting these together with an adhesive or the like. The upper plate 2 and the lower plate 3 are made of rubber, foamed synthetic resin, leather, etc., and the upper plate 2 has a plurality of through holes 4 vertically formed through its thickness.

It is desirable that each of the above-mentioned through holes 4 be opened at a position that does not contact the sole of the foot, that is, at a position between the toes, around the heel, or where the foot is not stepped on.

On the other hand, a groove 5 is formed on the upper surface of the lower plate 3 in correspondence with the through hole 4 . The groove 5 extends radially from a base end 6 opening on the upper surface of the lower plate 3 toward the side edge of the lower plate 3, and has a tip 7 open to the side edge of the lower plate 3. This groove 5 has a shallow proximal end 6 and a distal end 7.
has a deep slope, and if necessary, the distal end 7 can be made wider than the proximal end 6.

The groove 5 described above is formed for each through hole 4 of the upper plate 2, and when the upper plate 2 and the lower plate 3 are bonded, each through hole 4
The lower end of the groove 5 communicates with the base end 6 of the groove 5, and the through hole 4 and the groove 5 form a ventilation hole 8. Therefore, the upper surface of the upper plate 2 is communicated with the outside from the side surface of the bottom plate 1 through the ventilation hole 8, and the internal space width of the ventilation hole 8 is increased from the open end of the side surface of the bottom plate 1 toward the back by the groove portion 5. It gets narrower.

Furthermore, it is preferable that the grooves 5 described above are not formed in the width direction of the lower plate 3, but are inclined toward the toe side or the heel side. That is, the groove portion 5 located on the side of the lower plate 3 is inclined toward the toe side or the heel side,
The groove portion 5 located on the toe side or the heel side is directed toward the tip on the toe side or the rear end on the heel side.

Footwear is created by attaching an upper to the periphery of the sole plate 1 having the above-described structure. The ventilation hole 8 has an inclined shape that provides little resistance to the inflow of outside air. Therefore, the outside air can easily flow into the footwear from each ventilation hole 8, and when the footwear is worn while walking, the outside air can be forced to flow into the inside of the footwear due to the wind blowing phenomenon caused by the movement of the feet.

Furthermore, when wearing footwear and transitioning from walking to running, there is heat dissipation from the feet, frictional heat between the feet and the inside of the footwear, frictional heat due to repeated deformation of the footwear itself, and the above-mentioned wind blowing phenomenon. Since the airflow is also intense, outside air flows into the inside of the footwear in proportion to the running speed. Furthermore, the ventilation hole 8 becomes narrower toward the back from the open end of the bottom plate 1. Therefore, due to the above-mentioned wind phenomenon, the flow of outside air flowing in from the open end is accelerated in the process of passing through the gradually narrowing ventilation hole 8, and it blows into the inside of the footwear with a certain amount of wind pressure, making it difficult to wear the footwear. Even so, you will feel refreshed.

Moreover, even if sand or dust gets into the ventilation hole 8, since it is sloped downward toward the open end, it can slide off when worn, and will not accumulate inside the ventilation hole 8 and reduce the ventilation effect.

Furthermore, each ventilation hole 8 becomes shallower from the open end toward the inner end, and becomes thicker at the portion where the weight is applied to the sole plate 1 when worn. Therefore, the ventilation holes 8 will not be crushed even if the wearer receives body weight while wearing the wearer, and the comfort of wearing the wearer will not be impaired at all times.

Furthermore, during manufacturing, the upper plate 2 with the through holes 4 and the lower plate 3 with the grooves 5 are molded separately, and the ventilation holes 8 can also be formed by simply bonding the upper plate 2 and the lower plate 3 with adhesive or the like. Therefore, there is no need for special drilling or cutting, and it can be mass-produced extremely easily and inexpensively by molding, which has been commonly used.

In another embodiment of the present invention shown in FIG. 4, a middle plate 9 located between an upper plate 2 and a lower plate 3 is interposed in the heel portion of the sole plate 1 to make the heel portion higher. The ventilation hole 8 provided in the heel portion of the bottom plate 1 is connected to the upper plate 2.
It may be configured by a through hole 4 opened in the middle plate 9 and a groove 5 formed in the upper surface of the middle plate 9.
It may also be configured by a through hole 4 that is opened in series and a groove 5 that is formed on the upper surface of the lower plate 3.

As described above, the presence of the middle plate 9 makes the ventilation holes 8 formed in the bottom plate 1 highly effective, as in the embodiments described above.

Although the present invention has been explained above based on the embodiments shown in the drawings, the present invention is not limited to the above-mentioned embodiments, and can be implemented in any manner as long as the structure described in the claims for utility model registration is not changed. can. For example, in footwear that is known to have an insole placed on the upper surface of the sole plate, such as athletic shoes, the insole has through holes corresponding to each through hole so that the insole does not block each through hole 4. Alternatively, the inside of the shoe may be opened and the outside air can communicate with the inside of the shoe through the through hole, the through hole, and the groove to enhance the ventilation effect inside the shoe.

<Effects of the Invention> According to the present invention, the ventilation holes have an unprecedented configuration, which allows for extremely good ventilation into the interior of the footwear, and prevents stuffiness and odor from occurring within the footwear. Furthermore, it provides footwear that does not feel uncomfortable when worn and has extremely high practical value.
