The invention relates to a self-closing vent paste for textile, shoes or items collected, at least one of the first air permeable layer located on the first breathable layer of absorbent material, a second breathable layer coatings on top of the first and second air permeable layer and at least one layer of Foundation on one of the surfaces. The subject of the invention is also a method of manufacturing a ventilation insert through injection molding.

In everyday life desirable ventilation textile goods or items to ensure sufficient air circulation. So, for example, a jacket or shoes, at least partly supplied by the materials that are breathable, in order thus to ensure good air and moisture exchange. If air circulation is not provided, it is often the accumulation of moisture, and, under certain circumstances, even condensation. Therefore, a variety of inserts for ventilation of items manufactured, for example, of textile materials. Items supplied with holes, which are only covered with breathable material. The disadvantage of such holes is that they are not waterproof and can be Pronin is their water in them from the outside. For clothes or shoes are traditional, therefore, a variety of coatings, which are mechanically stretched over vent.

Have developed a variety of textile materials, in which it is possible targeted regulation of water and vlagopronitsaemostyu textile material. Permeable to water vapor materials, for example, microfaser fibers or membranes make it possible minor removal of water vapor, but do not provide air circulation. The corresponding planar textile material is described in EP 1054095 A2, where depending on the temperature the material is stretched or compressed and, consequently, opens or closes the vents. This textile flat material can, however, use only in certain areas, in which the opening and closing shall be regulated by temperature fluctuations.

From US 2005/0249917 A1 known membrane structure that allows for directional control of permeability depending on environmental conditions. This membrane structure is used, in particular, to protective clothing, in which water vapor must be removed from the internal space to the outside, but dangerous liquids or gases must not penetrate into the service. Described membrane structuralistic of two membranes, positioning them relative to each other is changed at a certain excitation. For operation of the membrane system at the manufacturer must precise positioning of the membranes relative to each other. Moreover, in the membrane system must be integrated energy source, for example, on the basis of the electrical excitation, which allows the displacement of the membrane relative to each other.

From the field of hygiene famous superabsorbents, which can absorb large quantities of water and swell. The water absorption is reversible, at a lower humidity environment, water is again given in the external environment. Such absorption sweats are used, for example, in diapers or feminine hygiene products, as well as in the construction industry. Such absorption sweats may not be used, for example, in the manufacture of clothing, as they would not provide sufficient comfort to wear. Equipped with absorption fleece jacket in areas with absorbent, very much swelled and would consequently not only would add weight, but the fit to other layers, as a result of contact transmission of moisture, give it moisture, for example, on clothing under it. In addition, the fleece material is very sensitive against mechanical damage is, and already hit the place containing absorption fleece, could cause damage, and absorbent emerged from the fleece. In addition, these materials are not waterproof, so as not related absorbent water seeps between the balls of absorbent material.

The objective of the invention is to provide a ventilating insert, which when in contact with liquids, in particular water, is automatically closed, in a dry condition provides good ventilation, closed without the use of mechanical cover and protected from mechanical damage. The ventilation insert should be designed so that it could be applied in various fields, as in clothing and shoes or coatings, and protective clothing or objects, in which it is desirable to have air circulation while protecting from moisture. Further object of the invention is to provide a method that enables rapid and cost-effective manufacturing ventilation insert on an industrial scale.

The problem is solved in a self-closing vent paste for textile, shoes or items collected at least one core element with the first air permeable layer located on the first breathable layer of absorbent material, which upon contact with the liquid in chastest the water, swells, the second breathable layer coatings on top of the first and second breathable layer, layer basics of coatings, and coatings and/or layers of the framework squeeze breathable layers and form the structure of cells, and at the expense of cameras is limited to the dissemination of the absorbent, but at the expense limit is the seal of the absorbent during the swelling process, which closes the vent insert. The closing is conditioned tactile contact of liquid or water.

The ventilation insert is assembled, at least one is filled with the absorbent core element, the upper and lower coating layer bases on the surfaces, and the method includes at least the following steps:

if necessary

A. placing a layer of wood element in the coating layer and the placement of the second coating layer on the core layer of the element

C. cutting the stamp base element or trim on the base element, for example, using a stamping tool or with a laser, at least a layer of wood element, perforation of the base element for the formation of through-holes and, if necessary, pressing,

C. positioning a perforated base member in the form for casting under pressure, prefer the Ino above devices for fastening,

D. the molding layer basis, and the layer material is the basis for casting under pressure is forced through the through holes of the base element.

The subject invention is also self-closing vent paste for textile, shoes or items collected, at least

one absorption layer with absorbent material, which upon contact with the liquid swells, and

- one layer of Foundation,

characterized in that the layer basics

- at least partly permeable to air, for example, perforated, and completely encircles the absorption layer, or

- is airtight and completely encircles the absorption layer to separate plots and

layer framework limits the maximum spread of the absorbent so that the limit is the seal of the absorbent during the process of swelling, which closes the vent insert.

The ventilation insert according to the invention is used, therefore, in two basic forms. One basic form is the main form of 1 - forms a separate element with the structure of the camera, and the camera's maximum limit distribution of the adsorbent. Such a variant embodiment of the invention is represented, for example, figures 1-3. The other main form the main form 2 - veins is ilational insert in accordance with the invention is a flat structure or integrated ventilation element, which distribution of the absorbent is limited by layer basis.

In the embodiment of the invention the core element of the breathable layer and the absorption layer and, if necessary, the upper and lower cover are arrangements for securing that make possible the positioning element in the form for casting under pressure. Devices for fastening are, for example, holes, the adhesive surface, structure, or pins that help or make it possible positioning in the mold for injection molding. Additionally or alternatively, devices for fastening are integral parts of the respective molds for injection molding.

The core element and, if necessary, coatings have advanced in the preferred embodiment, through holes, through which in the manufacture of ventilation insert is held flowable material layer basis. Through holes can be, for example, holes in the layers, which are preferably evenly spaced in the layer. When flowable material, for example polymeric material, while manufacturing flows through the through holes, at the same time formed the top and bottom layer basis, and, if necessary, a safety grille and connect the performance communications surface. In addition, the upper side and the lower side layer ground through material that fills the through holes, are firmly connected with each other.

Depending on the height and diameter of the filled through-holes, the clearance, which is available during the swelling of the absorbent is determined and recorded. In accordance with the invention preferably less fill flowable material to produce a layer basis outside passage holes through permeable layers, absorbent and, if necessary, of the coating. Through the use of through-holes are achieved significantly better results and connections. Through holes can be used in different amounts and have different shapes.

Separate sections of a layer basis, which connect the layers to each other, in the embodiment, in the form of a single element are arranged in such a way that bordering absorbent areas surrounded, for example, in the form of a ring or cell, so that the absorbent is tied to the layer structure in such a way that when the swelling he's limited in their distribution. Advanced introduction to the layer structure has an advantage in that the absorbent is held in position and cannot fall out of the vents. In any case, the fluid material from which the o in particular, consists of a layer basis, must be located so close to the border with absorbent areas were loose to ensure air permeability and water vapor. This can be obtained by additional perforation of the layer.

Additionally, through holes can also be used to place them in connecting elements, such as pins, which make possible the fixation located one above the other layers or components, hold the layers in a predetermined position or control their expansion/compression. This variant implementation of the invention is, however, less preferred.

Particularly preferred is the core element of the ventilation insert is made integrally from a breathable layer and the absorption layer, in a particularly preferred embodiment, in the form supplied by the absorbent fleece or non-woven material. In the embodiment of the invention the core element and the coating are made integrally, in a particularly preferred embodiment, in the form of a sandwich laminate.

For example, a breathable surface on one side covered with absorbent material, which forms the absorption layer and due to rounding breathable surface is formed from the first air permeable layer and the second breathable the layer, both covered with absorbent surface, appear lying on top of each other.

For both of the main forms in relation to the material and structure of the following options:

The absorbent material.

The absorbent is in the preferred embodiment, is capable of swelling the polymer, selected from the group of polyacrylic acid, polyacrylic acid copolymers and structured nationallyaccredited, or casein, protein or thermoplast-elastomer mixture. In a preferred embodiment, the adsorbent is mixed with the filler, and the filler with absorbent material together form the absorption layer. As the absorbent material can be used, for example, superabsorbents, such as HySorb® BASF AG or Favor® company Degussa AG.

If the absorbent or the absorptive layer is formed together with the breathable layer or a layer basis in the form of absorption of the fleece, as a material can be used, for example, Luquafleece ® BASF.

The choice of the adsorbent depends on what fluid should be used for swelling of the absorbent. When using water as a liquid is used, the preferred way above the superabsorbents. In the embodiment of the invention it is also possible to combine two or more absorption materials, so that one absorbent reacts to water is, and the other absorptive material on other liquid.

The absorbent may be, for example, also loaded, for example compressed by high pressure, or may be carried out additional flow between the layers of the framework.

The filler.

As filler can be used, for example, compounds of polymers, termoplastautomaties composites, fibers of animal origin, such as hair, feathers, leather, bone, horn, vegetable fiber, such as cotton, cellulose, cardboard, flax, coconut, skin, wood, fiber, vegetable, metal, mineral fiber, carbon fiber, rubber or materials or mixtures of them. Powder, or granules, or materials with heat properties, for example wax microcapsules. The filler is, for example, in order to reduce weight. If you use a conductive liquid or water material, it can, in addition, output absorbed the liquid or water in the absorbent due to the formation of purposeful contact transmission of moisture, and thus lead to faster evaporation of water. The filler and the amount of filler is chosen so that the swelling of the absorbent and the resulting closing of the vents does not entail any negative poles the Vij. If the filler is used for targeted education contact transmission of moisture, in the preferred embodiment, it is in contact with the surfaces of the evaporation vented on the object. Such surface evaporation can be, for example, the material of the outer side of the garment or Shoe. The use of such a filler makes sense especially when the material of the outer side itself cannot form a contact transfer of moisture from the material of the inner side and, thus, there is only a small surface evaporation. In a preferred embodiment directed in this case to the consumer side vents designed in such a way that it prevents the penetration of moisture into the interior.

Layer basics

Layer framework may consist of, for example, of the following materials or mixtures thereof: polymer compounds, polymer foam, termoplastautomaties composites, materials with surfaces of the nanoparticles, materials of animal origin, for example bone, horn, fiber, materials of vegetable origin, for example coconut peel, wood, grass, fiber, materials, compounds of carbon, for example carbon, metal, mineral composite materials, ceramics, glass, rubber, resin, leather, cardboard and/or protein combiner the private materials. The materials themselves or processed by injection molding, or incorporate, for example, polymeric materials.

In the embodiment, the basic form 1, the coating layer is part of the framework and carried out jointly in the manufacture of a layer basis. In the preferred embodiment, layer basics, forms a protective grille or protective layer, which protects the ventilation insert from damage, for example, from mechanical impact damage. If the layer basics at the same time forms a coating, the coating has in some areas of the openings, which are preferably formed by punching. These holes can be made, for example, by punching stamping, drilling, laser processing, melting, cutting, or can be formed already through the use of appropriate tools during the process of injection molding. In a less preferred embodiment, the breathable layer is formed integrally by layer basis, and by casting in moulds under pressure are formed corresponding vozdukhoplavanie holes and through the set of apertures provided an opportunity for the passage of air.

In the following embodiment, the main form 1 ventilation insert according to from what rutenium additionally has a connecting surface, which preferably consist of the same material as the layer of the base or cover, and in a particularly preferred embodiment is made as an extension layer basis. Connecting surfaces serve for fastening vents vented on the subject or material. The connection on the connecting surfaces may be performed, for example, by means of a magnetic connection, a snap connection, plug-in connections, connections with shear, surface connections, adhesive connections, connections in the fold, thermoplastic welding or stitching. Using the connecting surfaces of the ventilation insert according to the invention is located above the hole in vented textile product or in a ventilated subject in such a way that it completely covers the hole. In the embodiment of the invention the connecting surface is decorated with this in such a way that the ventilation insert according to the invention is performed with replacement. The ventilation insert may be designed as a disposable item, which after a single use is replaced. In a less preferred embodiment, the ventilation insert is used as an irreversible way self-sealing surface.

In a variant implementation, the program main form 1 connection surfaces are made so what possible replacement vent inserts on the new vent insert. This replacement can also serve to ventilated object to use the ventilation box with other characteristics, for example the ventilation insert, which has additional features. This variant embodiment of the invention is used, for example, in particular, protective helmets or electrical devices.

In the following embodiment, the main form 1 connection surface provided with structures or convexity and concavity, which make possible the consolidation of the vents vented on the object. The ventilation insert according to the invention can be designed in such a way that they in addition to the connecting surfaces or instead of connecting surfaces have connecting elements which make possible the fixation on the object. These connecting elements are, for example, additional structural elements, and the connection can be, for example, through the lining of the polymeric material in the extruder, by means of gluing, screwing, riveting, plug connections or knitting. The manufacture of the connecting surfaces is carried out with different thicknesses, depending on the area in which a change. In a preferred embodiment, the surface has a small thickness and outward taper off. In a preferred embodiment, the connecting surface can be textured during manufacture by injection molding or additionally by means of mechanical Cherkovna, etching, exposure to ultraviolet light or by treatment of such gases as ozone. Accordingly textured surface of the connecting surfaces facilitates the consolidation of ventilated object, if the connection method is selected bonding or welding, or something similar.

In the following embodiment, the ventilation insert according to the invention ventilated subject is designed so that the insert in accordance with the invention is part of the object. For example, in footwear, textiles or protective helmets vent insert in accordance with the invention, the preferred way is integrated into the object, for example, in the form of cast polymer products. So, for example, vents may be vulcanized to the Shoe sole.

Depending on the location of the connecting surfaces are preferably simultaneously as a sealing surface and the seal is twistie ventilated subject from air infiltration, dirt, dust, pollen and water.

The ventilation insert according to the invention can be connected to the object so that the selected connecting surfaces contribute additional rotation / alignment (connectors / magnetic connection / connection-shift). This makes sense when the user is properly equipped motorcycle helmet would like to adjust the ventilation surface before the trip to determine what amount of air or air flow needs to get into the interior of the helmet or protective suit, or in the inner space of the protective boots.

Design in accordance with the invention may have structures such as lamellae, which have a positive impact on air flow / air flow in resealable items (helmets, motorcycle suits). The corresponding structures can be very sensitive to the wind, that is, when a certain intensity of the air flow they springed would be due to the properties of the material from which they are made, and because of its design. The intensity and amount of air can thus be regulated automatically.

An additional layer, or a layer basis, or relief grating can be MSE is strayaway thus, what are the movable part of the structure. It is preferred when using protective helmets or goggles to adjust the ventilation effect, for example, by equalizing vent groove. The alignment may be performed using manual alignment or by electronic control, or may depend on environmental influences, for example the intensity of the air flow.

The connecting surfaces of the ventilation insert according to the invention in the embodiment of the invention is structured in such a way that the end user can for a long time to attach the vent box to the desired object as the "patch", for example, by means of surfaces with clamps, by means of stitching, adhesive, rivets.

Depending on the field of application of the ventilation insert according to the invention in both the basic forms can be designed in such a way that it contains additional flavors, dyes or substances and/or filter materials, which serve to improve falls inside the object air. When used as filter ventilation insert according to the invention can be coated, for example, activated carbon, silver and/or D. the natives scented or biologically active substances. Flavored or biologically active substances are served, if necessary, depending on the humidity.

In the embodiment of the invention, flavourings, colourings or biologically active substance is additionally applied by the user on the ventilation insert according to the invention or entered into it. So, for example, the ventilation insert into children's shoes can additionally be equipped with fragrances or dyes, so the child can individually arrange their shoes. Suitable biologically active substances are, for example, materials, destroying odor materials, providing antimicrobial action, or materials deterring insects. As one of the types of biologically active substances ventilation insert may be provided with an indicator materials that show when the vent insert has come in contact with substances that limit or hinder the health of the device. This indication may be, for example, by changing color. As biologically active substances can be added substances which accelerate the drying of the absorbent material, for example materials that remove the moisture from the absorbent or due to the flow of kinetic energy or chemical react and generate heat. It is also possible to perform the ventilation insert is heated so as to achieve rapid drying of the adsorbent.

The ventilation insert according to the invention is in a preferred embodiment, the structure / formation, which make it possible to waterproof the connection with resealable subject. This is especially important when the subject invention was made as a replaceable element. The ventilation insert may be used, for example, over the bulge made, for example, in the form of a circular edge, or concave, for example in the form of a suitable mating parts to a circular edge that subject. All together it is a plug-in connection, which makes possible the replacement and, depending on the details, provides a waterproof connection.

In the following embodiment of the invention breathable layers are connected directly with the absorbent, and the connection is made, for example, by a thermoplastic adhesive, primer, polymer material or glue. In this embodiment of the invention the material of the breathable layer and the absorbent is preferably metrazhnoj goods, whose first and second air-permeable surface located between the surfaces of the absorption layer is, if necessary, cover by passing through the surface of the holder are connected to each other, and the holder in the preferred embodiment, made in the form of strips, in the form of points, in the form of a circle or in the form of a line.

For example, at least one of the coating may be a direct part of the garment, for example jackets, for example its outer material.

In the following embodiment of the invention, the coating consists of a material of the inner lining and/or from the material of the upper layer. Thus obtained multi-layered flat material is made preferably as metrazhnoj material. In a preferred embodiment, the ventilated garment in this embodiment, partially or completely, consists of flat material.

In the preferred embodiment, both layers of the framework are made integrally and are produced mainly by way of injection molding. In another embodiment of the invention, the layer framework may consist of several parts, for example from adjacent each other and partially one above the other strips. In a less preferred embodiment, layers of Foundation on the lower side and the upper side arranged in different ways, for example, the lower side is made integrally as a perforated surface, EVERGREY side of several parts, for example strips.

When the layer bases are made integrally, between permeable layers are preferred manner of connection between the upper layer side substrate and the lower layer side of the substrate, and breathable layers, the preferred way is strongly connected to a layer basis, so breathable layers are fixed at a distance from each other. As a consequence, the chamber formed a certain value, which limit the distribution of the adsorbent. In a preferred embodiment, simultaneously coating layer through the basics firmly connected to each other, and the absorption layer predominantly smaller in diameter than that formed by coating chamber.

Air - and water-permeable portion of the material of the ventilation insert according to the invention is performed, if necessary, so that it is elastically fit dry absorbent, however, when distributing the absorbent limits the amount so that the absorbent is sealed to waterproof the surface. Layers of the substrate and connecting surfaces have as their goal is not only to reduce the spread of, or to prevent the spread, but can, in addition, to perform the task of mounting surface. This is important, for example, when used in text, is lnyh products gloves or shoes, in order to prevent the absorbent material through the permeable layers, if these layers are subjected to high loads. The problem can be solved by means of fillers, especially if they have a hollow space, for example, a sleeve of air - and water-permeable material, coatings that have turned to the absorbent structure, or designed in such a way that the absorbent is not very compressed.

The loading of the absorbent is prevented, for example, by covering elements, if they are connected with the floor so that the clip is filled with absorbent zone is reduced. The same function can be borrowed from the safety of the lattice or the protective layer, which protects the ventilation insert from mechanical damage, in particular from compression.

In the following embodiment of the invention the ventilation elements in accordance with the invention can be provided with an additional perforated coating that provides additional protection against mechanical impacts. It is for use in the protective soles shoes perforated holes can be located under a sloping angle to the underside of the Shoe sole, so as to prevent, for example, the vertical penetration is about acting foreign objects, such, for example as nails. The cover is preferably made from a material that provides effective protection against mechanical impacts, for example Kevlar.

Coatings can consist of various materials and can be made of fabric and non-woven material. Coatings can be produced, for example, from one of the following materials:

polymer compound, cardboard, leather, termoplastautomaties composites, Kevlar, ceramics, fibers of animal origin such as wool, bristles, feathers, leather, bone, horn, vegetable fiber, such as cotton, cellulose, flax, coconut, skin, wood, fiber, vegetable, metal, mineral fibers, human hair, carbon fiber, rubber, or a material, or mixture of them.

Coatings are made, for example, by injection molding, extrusion or calendering, in the form of a film or plate, and holes in the coating can also be made, for example, by punching stamping, drilling, perforation, laser processing, melting, cutting, or milling.

In a particularly preferred embodiment, the coatings are fine mesh, for example, a metal mesh or nylon mesh.

In the embodiment of the invention the blower adjust the operating insert in accordance with the invention designed as a textile flat structure or as part of a textile flat structure. These textile flat structures are either fabric materials or non-woven materials. In addition, there are flat structures that, at least in the zones of the absorbent are breathable holes and, thus, form a breathable layer. These holes can be optionally placed on the surface. These textile flat structure made in the form of a laminate or flat structure having a hollow space, which additionally filled. The hollow space is filled at least one absorbent material, which, if necessary, connected to the substrate. The choice of the hollow space is filled with filler, which also serves as the installation holder or as additional mounting brackets. Installation holders in the preferred embodiment, are balls that prevent strong grip surfaces.

Textile flat structure is preferably provided with structures such, for example, as a safety grid or layer basis. When using the textile flat structure, for example, by molding, grinding, firmware or other compounds, these structures can be located on the side facing outwards. These patterns serve, first, as a surface the values of evaporation, and secondly, to focus on the air flow. If the structure is designed as a safety grill or as ledges, they are, for example, as the installation brackets. If the textile flat structure placed between the material of the upper layer and, if necessary, the inner lining or other layer, for example, the inner protective padding a motorcycle helmet or inner lining of the jacket, the structure is formed of an air layer in which additional air circulation. Due to the formed air gap is formed, in addition, an insulating layer, which has a positive effect on comfort when worn. Choice patterns are only or in addition to facing the body side and can also take the above features and advantages. It is possible to have patterns on both upper and on the lower side of the flat structure.

If the ventilation insert according to the invention has components from polymeric materials, for example, when the layer of the substrate and/or relief grating at least partially made of polymer material, these components serve additionally as an installation surface or as a surface evaporation, as described in the previous embodiment of the invention.

Described is a flat structure can be manufactured, for example, as follows: breathable surface partially applied adhesive, and are left free areas, which later form a breathable hollow space. By applying adhesive thus treated areas become water-resistant. On the air-permeable surface is applied more adhesive, which is designed for fastening the absorbent. The adhesive substance may already contain absorbent or be mixed with them. On selection of the second adhesive can be applied to the installation brackets and/or fillers. The making of such a flat structure may, for example, by way of a clamp. This glue is designed to connect two breathable layers, and an adhesive substance to the absorbent, and the absorbent material are put in a single working pass.

A flat structure or design layer can have a different design.

Described is a flat structure, if necessary, in the manufacturing process are divided into permeable and impermeable areas, and, at least, breathable areas supplied by the absorbent before it is joined to the laminate. At least one layer of a multilayer flat structurine separate parts can be supplied at least one absorbent material, optionally the same base material and mounting bracket. Such layers can consist of mikrofaser fibers or membrane materials, which all surfaces are impervious to water but permeable to water vapor. The respective layers can be connected with each other by facing each other of the connecting elements, and bordering absorbent areas are left free. By facing each other of the connecting elements layers inseparably connected with each other. The connecting element may also be provided only on one surface. Lots of laminate that border and are at least in close proximity) with absorbent material, may optionally be made of a breathable, for example, by perforation.

If the connecting elements are located inside the laminate, it has the advantage that the multilayer planar structure in accordance with the invention not optically different from other surfaces that are not made in accordance with the invention. Self-closing breathable areas in accordance with the invention can thus seamlessly combine with non-functional surfaces.

In the next version assests the ment of the invention breathable layers are connected to each other so that they form a connected hollow body with a preferably round cross-section. For example, the hollow body can be made as a tube with holes, or may be formed by a hollow spaces, which are located in permeable zones of the surface. If the hollow body is designed as a tube, the absorbent is in the middle of the tube, a separate hollow body cavity can be connected to each other through a junction with a flat structure, which forms the Central element of the ventilation insert according to the invention. In principle, the hollow body can be filled with an absorbent material already in the manufacture or additionally, for example, via injection of the gel, which after drying forms a powder or granulate. In the embodiment of the invention with a hollow space or hollow bodies plots formed flat patterns are, respectively, permeable and breathable, while the area between the hollow bodies are formed preferably by means of waterproof surfaces, which, if necessary, are permeable to water vapor. Water and air permeability filled with absorbent zones may be, if necessary, implemented through additional placement of holes, for example, by perf the walkie-talkie.

In the following embodiment of the invention, the first air-permeable surface has a large number of concavity, which is filled with absorbent material and, if necessary, filler. Concavity close second breathable layer in the form of a coating. In a preferred embodiment, the second air-permeable surface by thermoplastic welding or by adhesive attached to the first air-permeable surface. In a preferred embodiment, the area between the individual chambers formed by the concavity, is waterproof, and this property can be achieved either by selecting the appropriate material or by connection type air-permeable surface, or by the type of coating or layer basis. In a preferred embodiment, the ventilation surface are, therefore, only within the concavity or cover the concavity. Concavity is made, for example, by stamping and simultaneously forming material, and, if necessary, during the process of stamping formed permeable surface, while the area of the concavity provided with perforations, for example, using a suitable instrument for stamping. Alternatively, permeable who previously due to the stamping surface may be closed, for example, by pressing, heating, or by attracting additional materials. The water resistance can be achieved also by applying another material, for example, by spraying on top of waterproof polymeric material. This material is in the preferred embodiment, forming a layer fundamentals of polymer material, which may also have the above-mentioned additional elements. Concavity can have different shapes, dimensions and patterns, both in regard to its internal surfaces and in relation to their outer surfaces. Concavity and its floor, or perched on top of her supporting layer are the same, if necessary, patterns or curves. In a preferred embodiment, the absorbent material is located on the side walls of the concavity.

In a preferred embodiment, the coatings have on the level of concavity protrusions of material that go into the concavity. The tabs serve as the installation of the holder against too much compression chambers and increase, thus, the mechanical stability of the cameras. If the projections of the material are arranged in such a way that juts into the absorbent, in virtue of the capillary effect, remove the water from the absorbent and placed it on the surface of the coating, where it evaporates. As a consequence, absorbent dries faster and the layer structure quickly becomes breathable.

Cover performed, if necessary, so that they form a bulge, which in the preferred embodiment, are located above the concavity so that the concave and convex form of spheres or curves of the two surfaces interact. In the following embodiment of the invention within the concavity is a separate structural element, which also consists of a breathable layer and in the center of which is absorbent. This individual structural element in the preferred embodiment, thus connected with breathable surface or coated structural element in accordance with the invention that the permeability takes place only in the area of the individual structural elements. Individual structural elements are hollow body filled with absorbent. The swelling of the absorbent limited to the form of hollow bodies, which in the preferred embodiment have a circular cross-section, material and volume of the hollow space. In the following embodiment of the invention the ventilation insert according to the invention has the additional conveying elements, which are in contact with the permeable layer and/or absorp the injecting layer and made preferred by way filiform, stripe-shaped or shaped. These conveying elements form a contact on transfer moisture and due to its capillary effect remove water from the absorbent material to the surface, increasing, thus, the surface evaporation. Absorbent faster again becomes dry, and construction in accordance with the invention again quickly becomes breathable. When filamentous surface evaporation are evenly distributed over the entire surface of the ventilation insert according to the invention as waterproof and filled with absorbent areas, the surface has a uniform staple length. After swelling of the absorbent surface evaporation, which is the preferred way are absorbent, protrude from the other surface, which contributes as an optical effect and more rapid drying caused by the protrusion of transporting items.

In the embodiment, the ventilation insert according to the invention in the form of a flat structure or a built-in ventilation element (the main form 2), it consists only of a base material and an absorption layer and an absorption layer on the outside is completely surrounded by the base material, which is made partially perforated or breathable or, at least, in megaprogramming directions surrounds the absorbent. In a preferred embodiment, such a ventilation insert is made as provided with absorbent material and to ensure that the gap knitted fabric.

In both of the major forms of the absorbent can be made as a plate-like product, which depending on the application of the cut. Opening after cutting edge, of which the absorbent material could fall, before using closed, for example, by stitching, catlike or drawing fluid at the time of processing of the material. Alternatively, the cut may exactly match the closing holes. Due to fit flush to the edge surfaces also prevents loss of the absorbent in the edge zones.

In the embodiment, the ventilation insert in the form of a flat structure (the main form 2), the binder can be wrapped, covered or caught or nonwoven breathable layer. The absorbent material is in the surface, for example in areas in the form of lenses, in the form of particles or in the form of strips, which include absorbent.

If the ventilation insert according to the invention is designed as a built-in ventilation element (based form 2), the layer framework made preferred by way of airtight material, which is partially perforated, or of the components of the ventilated objecttag, for example, when used in the sole of the Shoe, the layer framework can be formed in side walls of the duct, which limit the absorbent in its spread in almost all directions. Similarly operates the ventilation element in accordance with the invention, for example, if in the process of erecting the house it is placed between two or more ribs or plates, which constitute the next layer of the framework. In a preferred embodiment, the ventilation insert according to the invention in that case, if it is made as a built-in ventilation element has the form of a tube or sleeve and, if necessary, provided with thread-like absorbent material.

The core element of a single element or a flat structure in the embodiment of the invention is designed in such a way that the absorbent introduced into an adhesive substance or in solution, which, if necessary, can be applied by way of a clamp. This contributes to the compression capable of swelling of the surfaces that are covered and connected layer is provided with perforations at the level of the clamp absorbent, resulting in the textile flat structure or core element. In the next version breathable materials can be sealed adgesiruta substance nekotoruyu the next step is absorbent. Thus, equipped with absorbent surface at the level of placement of additional absorbent perforated. In all variants of the invention, the breathable layers as an additional characteristic can choose to have curves that have a positive impact on air circulation.

In an unexpected way through the ventilation insert according to the invention it was possible to make a good circulation of air inside the ventilated object and, in particular, the exchange of air from the inner space ventilated object with air from the environment, and the ventilation insert in the shortest time when contact with water spontaneously closes. As soon as the flow of water stops and the moisture evaporates, the ventilation insert is opened again, without having to open and close when the ventilation holes by the user using mechanical coatings. Revealed himself to the fact that another advantage of the ventilation insert according to the invention is that it is self-healing. While other water-repellent and breathable membrane is damaged, for example, as a result of drilling or perforation, when using the ventilation insert according to the invention this is not happening. If, for example, the needle or needles digging into the layers of the insert, and then removed, the hole is closed due to swelling of the absorbent and the user or the inner space of the object and continue to remain effectively protected from moisture.

The ventilation insert according to the invention is particularly effective when the absorbent has twice or thrice was activated by moisture. It was possible to observe that the maximum breathability and functionality increased, when the ventilation insert is performed in the form of a reversible vent insert has been "pre-activated".

Due to the structure with a layer of Foundation and, in particular, due to the construction with safety air grille insert, moreover, protected from mechanical damage, and can in a General way also be used in areas with high load. In a preferred embodiment, the ventilation insert according to the invention during the swelling of the absorbent only adds a little weight. Due to this, the weight of the ventilation insert does not affect the comfort when worn, and due to the small volume provides faster drying. Due to the structure of the ventilation insert according to the invention is prevented by the fact that due to the swelling of the absorbent is ncontroller is my swelling layers or "separation from each other". In addition, through the absorbent in the ventilation insert according to the invention, the moisture is released from the interior of the item of clothing, shoes or object outside. When a small amount of moisture absorbent material swells only slightly and thus brings moisture to the outer surface, if the ambient air has a high humidity. This works in the closed position, the vent insert, because the moisture on the surface evaporates and the moisture in the internal space is vented. Both open and in the closed position, the vent insert is thus the transfer of moisture from the inner space to the outside, so that the quality of the air in the inner space ventilated object is improved.

Formed, for example, through layers of foundations installation surface prevents, moreover, the transfer of moisture in those areas where its presence is undesirable, for example inner clothing. Through targeted placement of absorbent material in the cells can be prevented, moreover, excessive absorption by the absorbent of moisture, which occurs because of a violation of mass. The design of the ventilation insert according to the invention additionally protects the absorbent didn't get out of ventilation the second insert. The ventilation insert is for this, if necessary, breathable layer, porous so that the absorbent even under pressure will not be able to go outside.

To prevent contact transmission of moisture to the surrounding material or to the bearer of the relevant subjects, in the preferred embodiment, on facing the body side is used waterproof material or suitably equipped material. The formation of contact transmission of moisture, if necessary, additionally contribute components made of polymer material, such as layers basics, safety grilles and mounting surface. Preventing direct contact of the body with corresponding surfaces has the advantage not only that the air gap is formed, but, in addition, that the cold or the temperature outside is not passed on to the user through a damp absorbent material or other components of the ventilation insert. Converted to body structures have the advantage that, firstly, the air flow from the side of the body can circulate, and, secondly, when heavy sweating tactile contact through droplets of water, for example, sweat, in respect of the vents will not cause premature closure is party due to swelling and, thus, cessation of ventilation. For facing the body materials are used, for example, pleasant to the skin, however, waterproof materials. Such materials are, for example, microfaser fiber or membrane, which in some areas, which is absorbent, have a breathable holes and form, therefore, breathable layer. Due to the use of such materials advantage of the permeability of these materials to water vapor may be associated with improved breathability vents in accordance with the invention.

The ventilation insert according to the invention as in the form of a single element in the form of a flat structure or ventilation element can be used in a variety of applications. The use of vents in accordance with the invention are provided for ventilation of sleeping bags, tents, backpacks or bags, helmets, protectors, jackets, horse saddles, paddles for fermentation, protective clothing, protective helmets, motorcycle clothing, goggles or glasses, medical or orthopedic bandages, orthopedic or medical splints, prostheses, orthopedic devices, shoes, gloves, textile materials, coatings or flooring. Moreover, Venti is alonna insert in accordance with the invention can be used in packages, electronic devices, tower dryers, window frames, roofs roofs or in their component parts.

If the ventilation insert according to the invention is used in footwear, there are various options for its positioning inside the Shoe. The ventilation insert may be placed, for example, in the inner sole with integrated ventilation surface and can be positioned over the ventilation holes and/or, if necessary, the ventilation holes in the soles. The ventilation insert according to the invention is then as the sealing device and prevents the ingress of water. The ventilation insert in a Shoe sole made of polymeric material, or leather, or other conventional material soles functions then by the type of tube. In a preferred embodiment, the ventilation insert according to the invention for this application has over a layer basics additional covering element, which prevents the entrance of contaminants or loss of absorbent material.

When all the possibilities of using absorbent or executed as a separate structural element that is replaceable if necessary, or is a permanent component of the ventilated facility. When the absorbent material is located in a ventilated object is necessary or invisibly. For example, when used for ventilation of clothing or shoes, the ventilation insert according to the invention of optical considerations may be covered with a breathable material or material with holes.

The ventilation insert according to the invention in one of the embodiments is designed as reflective. In addition, can be selected plastics/materials that glow in the dark as lanterns (phosphorescent or fluoresce or glow due to electrical voltage.

The ventilation insert according to the invention in a preferred embodiment, can be washed or dry-cleaned.

When selecting materials for the manufacture of ventilation insert in accordance with the invention, these inserts preferred way to adapt to the particular scope of the object. So, for protective gloves, suits, hats and shoes are used, for example, materials that minimize traumatic, such, for example, as particularly stable grid, or several layers of permeable materials, or stable protective grating or cover. As components of the ventilation insert according to the invention can also be used nanomaterials with soil-repellent and videotalk the sponding properties. This prolongs the period of permeability and delays the moment of closure to protect from water and dirt. In the embodiment of the invention, in which the ventilation insert according to the invention is placed in the Shoe, the ventilation insert is placed in the Shoe sole during manufacture of the Shoe. In the preferred embodiment, it uses a structural element, at least two, preferably three absorbents, United with each other, so that one of the ventilation insert is inserted into the sole, and two others, for example, United with her in a circle vents are located, respectively, on the outer side of the Shoe.

The use of the ventilation insert according to the invention should be explained hereinafter on the basis of the following examples of carrying out the invention:

Some applications explained in the following, for example, in more detail:

- When used on the surface of the ventilation insert may be, for example, part of a bus to protect the foot or part of a protective helmet.

- Ventilation insert may be used for ventilation military protective devices and protective clothing. For example, in protective suits pilots of jet aircraft, which are under the influence of excess pressure, ventilation the second insert prevents the penetration of water, because the pilot may be forced to leave the plane in an ejection seat.

- When used in medical equipment ventilation insert may be used in the tires, which are superimposed after fractures, or in protective coatings after injury. Due to improved air circulation accelerates the healing process and provides, moreover, a high level of comfort when worn. This application is possible both in veterinary and in human medicine. In this embodiment of the invention the ventilation insert may be provided with, in addition, a dye that visualizes how long the bus must be to wear. In addition, can be used hydrobromide dyes, which show when the bandage or splint has come in contact with water and, as a consequence, if necessary, should be replaced.

- Ventilation insert may also be used in furniture, for example, in the surface for lying or sitting in the buggies, devices for carrying children or child car seats. Because of this, it is possible ventilation while protecting from moisture and humidity. The ventilation insert according to the invention can be used in construction, for example, for ventilation of buildings, in a well-closed Windows, or with good isolation.

Other possible applications of the ventilation insert according to the invention apply to coverage, awnings of synthetic material and the housing, such as cable harnesses, fuse boxes, boxes for spotlights, in which through the use of vents can be prevented accumulation of condensation. This prevent the accumulation of condensation is also possible with the ventilation insert according to the invention in appliances, cars, motorcycles, residential cars, the holders of posters, tents, sleeping bags, shop Windows or greenhouses.

- Ventilation insert may also be used for ventilation special tanks designed for the storage of absorbing moisture or liquid materials such as construction materials (cement, glue), feed, food or medical products.

- Ventilation insert may contain, along with the absorption of biologically active substances and therefore can be made as a special filter, for example, for use in a protective helmet, the vacuum cleaner or a respirator. If the absorbent in the ventilation insert is used in combination with activated carbon, activated carbon affects the smells, while the ventilation insert at the same time prevents the ingress of fluid to the electronic device.

- Ventilation vs the Aqua may be placed in service, surface or object so that it serves as a special valve and as an emergency layer water barrier, or as a barrier for the liquid. The ventilation insert may be connected with electronic sensors that, for example, turn off electronic devices or trigger specific actions when the ventilation insert came in contact with water or liquids.

- Ventilation insert may be designed in such a way that functions as a feeder current: in this embodiment of the invention one coating layer made of copper, and opposite him the coating layer of a different material, for example, of zinc. If located between the coating layers of the absorbent material becomes wet, there is an electric current which, for example, can be used for signal generator, such as an led or other electronic device, or run the wiring diagram. For example, when used in children's clothing or children's shoes, this makes it possible that this clothing or shoes, when it becomes damp, flickers or makes sounds. However, a single camera vents can be as batteries serially connected to each other.

For the presentation of the ventilation insert according to the invention on the and can be integrated in the control device. The control device is, for example, from one that is open on one side of the hollow body, in which is placed the ventilation insert. In the closed position through the ventilation insert, by analogy with the tube, you can blow out air. When the ventilation insert is hydrated, it closes that in the control device causes the air can no longer be blown through.

The ventilation insert according to the invention in one of the embodiments of the invention are formed by the material of the garment or Shoe. So, for example, corresponding hollow spaces or holes could be placed in the sole of the Shoe which is placed in the absorbent. This involves:

- The use of a flat layer of absorbent material.

- Permeable side walls.

- Surface evaporation, which are in contact with absorbent material or with a material base. For example, the base material is moisture-permeable and, if necessary, only in some areas equipped with absorbent material. Surface evaporation can go into the interior of the Shoe and to speak of the Shoe.

The ventilation insert according to the invention can also be designed as a coupling element. In this case, having the form of a pipe layer framework around the core ele is UNT or absorbent. When the absorbent material swells, as he tube closes the tubular element. When used for the stub of the absorbent element can be performed, for example, as the absorption fleece or as filamentous carrier covered with absorbent material.

In the following example embodiment of the invention, the binder serves to education breathable inner sole. The inner sole on its lower side is provided with absorbent material, for example, hollow vignette. The material vignette represents, thus, a layer of Foundation vents in accordance with the invention. Vignette have slits in the material, which create an air connection between the inner space of the Shoe and the holes of the Shoe sole. The sole of the Shoe at its outer side also has openings, which are connected with vignette. Upon contact with water present in lignotech absorbent is sealed and openings and slits in the material vignette closed. Presents as an example the inner sole can also be designed in such a way that it does not have slits in the material, if vignette or other openings in the Shoe soles are located or designed so that when not swollen absorbent possible circulation of air through the holes of the Shoe sole. Through the vents, p is the iMER, in the form of a vertical stub element, vignette may also be associated with the holes of the Shoe sole. Vignette can be made in the form of a sleeve placed over the holes of the Shoe sole and to be filled with absorbent. When the swelling of the absorbent structure vignette then deformed in such a way that they are pressed tightly together.

The following example implementation of the invention are the shoes or soles of boots that have vozduhoprovodyaschih channels. In vozduhoprovodyaschih channels may also be absorbent, which prevents the ingress of water. If vozduhoprovodyaschih channel is connected with the holes in the bottom of the Shoe, because of this, it also provides the opportunity for ventilation, however, due to the presence of the absorbent material to prevent the ingress of water; absorbent performed, thus, in the preferred embodiment, as a built-in ventilation element.

In both the examples described above for use in footwear the incoming water is absorbed and due to the swelling of the absorbent vozduhoprovodyaschih channel is closed before the water reaches the interior space of the Shoe or thereby of the foot. At the same time improving comfort when wearing shoes, as located in the inner sole or vozduhoprovodyaschih channel the absolute is bent wicks away moisture from the inside of the Shoe.

Described as an example of the inner sole or firmly affixed to prevent the entry of water on the side edges or surfaces that are not sealed absorbent, or they have connecting surfaces that are sealed.

Described in the embodiments of the invention vozduhoprovodyaschih channels may also be applied in other areas, for example in protective helmets or appliances, and can be closed by the ventilation insert according to the invention.

In the embodiment, the main form 2 ventilation insert according to the invention is made filiform, i.e. vozduhoprovodyaschih layer is made, for example, in the form of a sleeve or tube, and filled with absorbent material, if necessary, together with the base material. Absorbent material with the base material may also be, for example, absorbent fleece. If this ventilation insert according to the invention is used in filamentary form, and under the thread refers to the smallest surface shape, it is like the thread is closed or placed into the holes. In the dry state through holes can circulate the air. If the "thread" swells from moisture, the holes are closed.

The absorbent material and the filler material in the next version of the wasp is estline of the invention is magnetic or responsive to the energy field. This is achieved through the use of appropriate materials or impurities and compounds. This allows you to affect the orientation or location of an absorbent and/or filler. If the filler / binders are vertical hollow space, for example in the hole of Shoe soles, these materials in the dry state would be on the lower floor. Air circulation was already limited due to the presence of "granulate". If the sidewalls of the hollow space magnetized or, on the contrary, is granulate, these parts of the granules are collected on the sides and this will release the air circulation through the hollow space.

This effect can be achieved through a continuous energy field or purposefully obtained by application / free power-on sequence. Next, the energy field can be placed in the range of, for example, by a mechanical shutter, which is a part of the object, for example Shoe. The magnet could be aligned, for example, by means of an adjustable mechanical device or a sliding device with the user and with the help of electronic devices.

Materials and characteristics of the ventilation insert according to the invention are consistent with areas of note is in or selected accordingly. So it is possible, in particular, to the degree of crosslinking of the absorbent material, as, for example, the degree of crosslinking polyacrylic acid for use inside items of clothing that was different than the inside of the Shoe, in which the user is exposed to a large number of chemical substances or the environment. In addition, the material or materials can be adapted for use in certain applications and in the ventilation insert on separate sites may be different. When using ventilation inserts for tires used in fractures or as protection for injuries (plasters, bandages for wounds), significantly helps, if appropriate insert for the treatment of fractures are little elastic or not elastic, and on the wrong side facing the body, have a nice body materials and/or biologically active substances. On the contrary, the surface is prescribed for use in protective helmets, may have different material characteristics than the surface used in tents or clothing items.

If the ventilation insert according to the invention is used in an area where it is exposed to high mechanical loads, for example, a compressive load, the ventilation insert may further have predochranitel the data grid, to prevent compression filled with absorbent areas and provide the pressure distribution, which protects filled with absorbent surface. In a preferred embodiment, the ventilation insert in areas with strong mechanical effects designed in such a way that is filled with absorbent surfaces are not loaded. This is, for example, is possible because the layer basis between filled with absorbent areas is performed as a hinge or made of elastic, flexible.

Next explained in more detail the method in accordance with the invention.

The footwear has an upper part, main insole, and removable insole and formed sole with heel, where three-chamber pneumatic pump is installed. Pneumatic pump is provided with three chambers for air supply to plantar foot part and closed with round plates from above. The said round plates are cut in the main and removable insoles. There is a number of open-end slots and holes made in the plates. The three-chamber pneumatic pump cylinder bottom rests upon the internal surface of heel cavity. The low piston is leant against retracting and cushioning spring. The channels of air distributing system are made on the footwear sole surface not engaged in walking. The outlet of discharge pipelines are located right under the proper hole made in the main and removable insoles of the footwear sole. The shim is provided with grooves made in each 90° to hold it tighter by balls located in pneumatic pump cylinder wall. After adjustment, a plug made from the same material is inserted in the sole hole. During walking, in the front push area, load increase is transferred to the footwear heel where cut-in discs are available in the main and removable insoles. The load is then transferred to the upper piston of pneumatic pump through the said round plates. The air is forcibly released from the upper chamber by piston through the holes available in the said piston, main and removable insoles to blow and cool heel and back part of foot. The pump piston-rod actuates the low piston, which releases air from the low chamber through the exhaust outlet and delivers it to the distributing system of air pipelines to blow and cool toe part of foot. Simultaneously, it compresses retracting and cushioning spring. Air is pumped from the environment to the corresponding chamber during back push. Air is moved in medium chamber as in opposition phase.

EFFECT: technical result is achieved when footwear is used and lies in increased conform due to forced blowing on plantar surface of foot and foot sides by means of three-chamber pneumatic pump.
