Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION The present invention relates to a shoe having a special system for facilitating the evaporation of the foot in the shoe.

[0002]

BACKGROUND OF THE INVENTION Recently, in order to allow the evaporation of the feet in shoes,
2. Description of the Related Art Shoes are known which have holes formed in the sole of the shoe so as to be easily circulated with the outside air of the shoe during walking.

[0003] At first glance, the shoe structure of the perforated shoe sole seems to easily remove the moisture generated in the shoe as appropriate,
However, in practice, the desired results have not always been appropriately achieved. Said hole structure in the sole has the disadvantage that during use the dust, mud or other substance particles enter into the hole, so that these holes are closed and the space between the inside of the shoe and the outside environment Airflow was obstructed or reduced.

[0004] Furthermore, and most importantly, especially in children's shoes and in adult's shoes, the perforated shoe sole in question also provides hygiene to contaminated environments (such as public baths). That is not to do. The membrane body can actually be impregnated with organic or non-organic substances contaminated by bacteria or in various ways, and therefore, in the case of drag walking, the foot of the person wearing this shoe It is possible to penetrate and contact the part.

More recently, shoes are available on the market that use a synthetic material that evaporates air but is impermeable to the passage of water, and that forms the entire upper or almost the entire upper.

[0006] However, the above-mentioned transpirable and impervious material forming the upper part is made of a woven fabric, so that the outer part of the upper part of the shoe of the general type, that is, the upper part is appropriately shaped. It cannot be used for parts that are extremely decorated with leather or the like. Therefore, it is possible to manufacture the entire upper part from these transpirable and impervious materials only for shoes and the like intended for aphtoskies, but not for normal upper parts such as leather. It does not limit general or sports shoes that are formally formed as a substitute for materials.

[0007] The use of these transpirable and impervious materials laminated on the outer element of leather as a lining of the upper part of a typical shoe can improve the impermeability performance of the general shoe. While improving, these impermeable and transpirable materials do not take advantage of the acceptable evaporative performance. Indeed, the leather on the outer element of the upper must be of a special type that is not dyed or covered and that is completely unprocessed and does not allow the proper passage of air,
Thus, the use of these materials in a synergistic manner does not allow for proper transpiration between the interior and exterior of the shoe.

It should also be noted that the above-described transpirable and impervious textile materials made of synthetic materials are generally very expensive, so that they cannot be used in large quantities as an inner lining. That is to raise footwear costs considerably.

Still further, it should be appreciated that the use of these synthetic and transpirable materials as linings requires special machining techniques, which are associated with high labor costs and footwear costs. And can be carried out with great effort (which cannot be carried out by ordinary footwear manufacturers) only by a specific person under the detailed instructions from the manufacturer of the transpirable and impervious material .

Furthermore, and very importantly, these transpirable and impervious materials which are applied as the lining of the upper part of a common shoe are made of a material which is made of synthetic, imitation leather or dyed leather. If it is a material that does not allow any transpiration, such as coated or polished leather, it will not work.

[0011] French Patent No. 2,216,790 discloses a transpirable upper structure which perforates a portion of the upper and coats it with an impervious and transpirable material. And the latter is configured to be stitched around its perimeter to a perforated leather portion.

[0012] This transpirable upper structure has the disadvantage that the impermeability of the shoe is effectively impaired since water always penetrates through the sewing holes and reaches the inside of the upper.

[0013] Also, the impervious and transpirable elements are exposed to the action of the feet from the interior of the upper, and their efficiency is quickly damaged by frictional wear.

[0014]

SUMMARY OF THE INVENTION Accordingly, it is an object of the present invention to provide an impermeable shoe which ensures a high degree of transpiration or exchange of air between the inside of its upper and the outside environment. To provide shoes.

It is another object of the present invention to provide a shoe, especially a general or sport shoe, wherein said high transpiration of the foot in the shoe is the upper, and the whole is the upper. It is an object of the present invention to provide a shoe which is achieved in cooperation with an upper part formed of a usual material which does not have a transpiration property by itself such as leather.

Yet another object of the present invention is to provide a shoe of the type described above, which has good durability and low manufacturing costs.

Still another object of the present invention is to provide a shoe having a ventilating device inside the shoe, wherein the shoe model or use is not changed by application of the device. It is in.

The above object is achieved by a shoe having the features of the appended claim 1.

The dependent claims relate to preferred embodiments of the invention.

[0020]

Preferred embodiments of the present invention will now be described in more detail with reference to the accompanying drawings.

FIG. 1 shows a shoe 10 comprising an upper part 12 and a sole part 14. According to the invention, a foot evaporation system 1 is provided inside the shoe.

In the embodiment shown, the system has a transpiration feature 16 provided in the side of the upper, said side of the upper facing inward, ie during use, the other side of this user. It is oriented toward the shoe side.

The perforated hole 16 is formed substantially at the center of the inner side of the shoe as shown in FIG. 2, that is, substantially at the center of the sole of the foot P as shown in FIG. And the sole of the foot has a general arch shape rising from the bottom, so that a kind of air chamber C is formed between the corresponding upper wall of the part 16 and the foot, and By varying the volume during this time, the air is easily discharged out of the shoe. In this way, a maximum transpiration effect is achieved.

It is noted, however, that for the present invention, the application of the evaporation device 1 to any other position of the upper or the application of a series of holes to another part of the upper may be envisaged. Should.

As shown in FIGS. 1-3, the transpiration system 1
Inside, the transpiration portion 16 has an element 24 of air transpiration and water impermeable material inside, which completely covers the portion 16 provided with the transpiration holes 22.

Element 2 of a transpirable and impermeable material
The peripheral edge of 4 is attached via simple or waterproof stitching, gluing or welding along the inner line of upper 12 surrounding perforated portion 16. According to the invention, a further element 26 is also provided for coating the intermediate element 24. The final covering element 26 is preferably attached with its peripheral edge along the peripheral contact line between the evaporating part 16 and the intermediate element 24.

The covering element 26 must allow humid air from the interior of the upper to pass through the intermediate element 24 and the perforated upper 16 to the external environment at any time.

The final covering element 26 is implemented through simple sewing or other techniques that do not achieve an impervious attachment of the intermediate element 24 to the perforated upper portion 16. In such cases, it has the following two purposes. That is, the covering element is designed in such a way that the peripheral contact line between the intermediate element 24 and the perforated upper 16 can be imperviously sealed (waterproof sewn, impervious) Protection against the friction of the foot of the intermediate element 24, which gradually leads to deterioration of the intermediate element 24 itself and a loss of efficiency. Must be guaranteed.

If the attachment between the intermediate element 24 and the perforated upper part 16 is already waterproof, use the garment element 26 to form an impervious or waterproof attachment on the evaporator 1. Is preferred but not necessary. This is not the sole requirement, but mainly as a protective element of the intermediate element 24.

In this embodiment, the perforated upper 16 has a triangular shape, as can be seen from the figure. However, in the present invention, other shapes different from the triangular shape can be foreseen. In the case of shoes, the perforations can extend over substantially the entire upper.

The internal evaporative and impermeable element 24 is preferably a Goretex ™ or Simpatex
(Trademark), but any material that effectively allows the passage of air but blocks the passage of water,
Either can be applied to the present invention.

The covering element 26 must have adequate wear resistance against foot friction, while it must be comfortable for horizontal placement of the foot, but with rubber or rubber with holes for the passage of moist air. It can be made from other synthetic materials or from other materials, such as, for example, untreated naturally evaporated leather.

In the second embodiment of the present invention shown in FIG.
On its upper 12 'may be provided some of the evaporation systems of the type described above.

Here, in addition to the evaporation system 1 'on the adjacent side walls of the pair of shoe uppers, another evaporation system 1 "is provided on the opposite side walls of the pair of shoe uppers.

The structure of the transpiration upper embodying the present invention can of course be applied generally to all material uppers and uppers of both standard and sports shoes, as well as to shoe uppers. It is possible to guarantee its effective and continuous transpiration without changing its appearance.

It is to be understood that what has been described with reference to the preferred embodiment of the invention is merely an illustrative non-limiting embodiment of the claimed concept.
