Description

[Detailed Description of the Invention] The present invention relates to a sole material for footwear with improved breathability.

Traditionally, footwear has had poor breathability, often causing problems such as athlete's foot and foul odors adhering to socks. Various methods have been tried to improve this, but only the use of insoles containing deodorizers or meshing the outer surface of footwear to improve breathability have been put into practical use. No improvements were made.

Therefore, the present invention provides a sole material for footwear that improves air permeability by actively flowing air inside the footwear.

The sole material for footwear of the present invention, as shown in the drawing, is made up of a sole material body A covered with a surface material B, and has an elastic material inside the heel portion of the sole material material A that acts as a pump by pedal force. A chamber 1 is provided, and a cavity 5 is provided in the inside of the toe portion, in which a ventilation hole leading to the outside of the sole material (inside the footwear) is present on the upper surface, and the chamber 1 has a conduit 2 leading to the outside of the footwear, and A conduit 3 leading to a cavity 5 is connected, and at least one means 4 for controlling air flow in one direction is attached to at least one of these conduits 2 and 3, and it is suitable for wearing footwear. Sometimes the air inside the footwear is caused to flow through the chamber 1 due to the force of the footwear.

The sole material of the present invention may be used directly as a sole of footwear or as an insole of footwear.

Since the chamber 1 acts as a pump by compressing and expanding according to the pedal force, the main body A of the bottom material is preferably made of elastic rubber, plastic, etc. If necessary, an auxiliary material may be installed in or near the chamber 1. It may also be provided with a plastic or metal spring.

When the sole material of the present invention is used, when wearing footwear, chamber 1 acts as a pump due to the pedal force every time you walk.
Air is introduced from conduit 2 and passes through conduit 3 to cavity 5.
Fresh air is sent into the footwear through the ventilation holes on the top surface, or by installing the check function in reverse, dirty air inside the footwear is sent from the ventilation holes on the top surface of the cavity 5 to the cavity 5 and the conduit. 3 into the chamber 1 and discharged to the outside through the conduit 2. Fresh air is introduced into the footwear through the opening of the footwear, and fresh air is always introduced into the footwear, thereby effectively preventing foot stuffiness.

Control means 4 for controlling the air flow in one direction, such as check valves, are attached to the conduits 2 and/or the conduits 3 so that air can be introduced into the footwear through the chamber 1 or from the inside of the footwear to the outside. It is controlled arbitrarily whether it is discharged to Although the check control means 4 may be simply attached to the conduit 2, it is effective to attach the control means 4 to the conduit 3 as well.

Note that the ventilation holes on the surface of the space 5 may be used as is if the surface material B inherently has ventilation holes, such as woven fabric, knitted fabric, nonwoven fabric, reticulated plastic, or metal sheet. However, holes may be actively formed in the surface material B. As the surface material B, fabric, synthetic leather, plastic, metal, or a composite thereof can be used. Note that it is preferable that the space 5 is present at least where the toes are located.

Since the cavity 5 is made of an elastic material and has a pump function, its presence promotes the air circulation effect more than in the case of the chamber 1 alone. Alternatively, the cavity 5 and the chamber 1 may be integrally molded, and the control means 4 may be attached to the center or the arch of the foot.

Even if one each of conduits 2 and 3 is provided,
A plurality of them may be provided, and the shape is not particularly limited.

The bottom material of the present invention becomes even more effective by the attachment of therapeutic agents, perfumes, deodorizers or desiccants in at least one of the conduits 2, 3 and the cavity 5. Incidentally, it is preferable that such a drug be formed into a cartridge so that it can be attached to and detached from the bottom material at will.

In the example of the drawing, the solid line arrows indicate the air flow when air is introduced from the conduit 2, and the dotted line arrows indicate the air flow when the air inside the footwear is discharged to the outside from the conduit 2. But in any case,
With this invention, when the footwear is worn, an active air flow is generated inside the footwear, so moisture and odors inside the footwear are forcibly removed, preventing the feet from getting stuffy, preventing athlete's foot from occurring, and preventing bad odors from adhering to the socks. can be prevented very effectively.

The conduit 2 leading from the chamber 1 to the outside may open in a part of the foot or in the area that touches the arch of the foot, and the opening may be located at the mouth along the wall of the footwear. It may be formed as long as

Examples of the use of the present invention are shown in the drawings. Fig. 1 shows an example in which the sole material of the invention is used in the sole of a shoe, and Fig. 2 shows an example in which the sole material of the invention is used in an insole.

In all of these examples, the bottom material main body A is formed of an elastic polyurethane foam, and the surface material B is made of synthetic leather.
