Description

[Detailed description of the invention] "Purpose of the invention" The present invention relates to the invention of moisture-permeable waterproof shoes, and aims to provide a novel moisture-permeable waterproof shoe that can efficiently achieve moisture permeability even on the sole surface. It is something.

(Industrial application field) Shoes that are waterproof and breathable.

(Prior Art) It is well known that waterproof shoes give the wearer a feeling of stuffiness. Therefore, in order to eliminate the stuffy feeling in such waterproof shoes, various proposals have been made in the past regarding the use of moisture-permeable waterproof fabric or the like as the upper material. For example, a moisture-permeable waterproof fabric is used as the upper material, or a bag-like body is formed from the moisture-permeable waterproof fabric to cover the foot, and this bag is attached to the inner surface of the shoe.

(Problem to be solved by the invention) However, in the conventional shoes as described above, even if a certain degree of moisture permeability can be obtained on the instep surface, when such shoes are worn, the foot The sole surface of the shoe, which is said to account for more than 60% of the amount of perspiration in shoes, is a closed structure made of synthetic resin or rubber, which greatly impedes the moisture permeability effect of the upper surface and the resulting sense of comfort. be done. In other words, even though it is said to be waterproof and breathable, the specific moisture permeability effect is at least on the sole surface of the foot, which is important.
It is inhibited by more than 60% and does not provide a comfortable feeling to the wearer.

"Structure of the invention" (Means for solving the problem) A shoe upper body formed of waterproof and breathable fabric, a shoe sole body provided with ventilation holes, and a space between the shoe upper body and the shoe sole body. A moisture-permeable waterproof shoe characterized by comprising a layer of wire mesh or other protective porous material interposed therebetween and bonded to both parts together at least at the edges.

(Function) A close bond is formed when worn,
In addition, they bond together under the action of body weight, forming a certain frictional bond, and allowing ventilation and moisture permeability through the ventilation holes on the sole surface of the shoe, which produces a lot of sweat. During movement during walking, the phenomenon of high pressure and low pressure is repeated within the shoe, increasing the ventilation at the sole surface of the shoe. Although irregularities are formed on the outer surface of the sole for the purpose of preventing slippage, the ventilation holes are opened in the recesses to make the above-mentioned ventilation and moisture permeability effective.

The wire mesh or other protective porous material layer prevents the waterproof and breathable fabric and the sole of the wearer's feet from being damaged by foreign matter that enters through the ventilation holes in the sole of the shoe, and therefore prevents damage to the waterproof and breathable fabric and the sole of the wearer's feet, even if the ventilation holes have a relatively large diameter. good.

In any case, the above-mentioned ventilation and moisture permeability from the sole surface prevents stuffiness and allows comfortable walking while wearing the shoe.

(Example) To explain a specific embodiment of the present invention as described above as shown in the attached drawings, a shoe upper body is constructed using a waterproof and moisture permeable fabric such as a porous polytetrafluoroethylene film. A protective porous tissue material layer 2, such as a wire mesh having a fine structure, is attached to the bottom surface of the shoe upper body 1, including the bottom surface thereof, and a Then, the sole body 3 is attached. As the protective porous structure material, a wire mesh made of an incorrosive or corrosion-resistant metal such as stainless steel, a mesh-like sheet made of a synthetic resin such as polypropylene or polyethylene, a continuous porous synthetic resin foam, or a knitted or woven material made of natural or synthetic fibers can be used. On the bottom surface of this shoe sole body 3, a concavo-convex portion 4 is formed which is connected to the side edge for the purpose of preventing slippage, and the concavo-convex portion 4 is formed in the trough portion of the concavo-convex portion 4, that is, the valley portion viewed from the bottom surface of the shoe sole body 3. A ventilation hole 5 opened on the top surface is provided.

The shoe upper body 1, the protective porous tissue material layer 2, and the shoe sole body 3 are connected by adhesive, sewing, or other connecting means.
The adhesive is attached to the edges of the sole body so as not to impede the ventilation and moisture permeability of the shoe.

``Effects of the invention'' When the present invention as explained above is used, it is possible to bond under weight-supporting conditions when walking while wearing it, and therefore it is possible to achieve effective ventilation and moisture permeability to the soles of the feet, which sweat a lot. This is a highly effective idea in practical terms, as it allows moisture to be properly removed from the soles of the feet, which is said to account for more than 60% of perspiration, and allows comfortable shoes to be worn without feeling stuffy.
