Abstract

The insert has a layer formed by an open-porous, water-permeable and water vapor-permeable surface (6a). Another layer is formed from a swelling material e.g. absorber. A third layer is formed by a water vapor and air-permeable surface (6b), and a distance surface (8) faces textiles and/or shoe interior space, where the former and latter layers are joined together directly and the former layer is bordered through the third layer. An independent claim is also included for a shoe comprising a ventilation insert.

Description

The invention relates to a ventilation insert for ventilation of textiles or shoes and a ventilated shoe comprising an outsole, an insole, an insole, an outsole connected to the shoe upper and ventilation openings in or in front of which a ventilation insert is arranged, as well as an insert with venting device for shoes ,

Waterproof textiles or shoes often have inadequate air exchange with the ambient air. This problem is solved by various devices that are intended to provide improved air circulation.

Open or porous materials still provide the most effective means of air exchange and the associated removal of water vapor and heat. Openings or material breakthroughs, for example inside the shoe upper, in some solutions have closure options or covering elements which, after manual closure or opening, prevent water from entering or allow targeted ventilation. Corresponding cover elements are fastened for example by zip or Velcro fasteners in their position or they are more permanent part of shoes and are changed by pivotal or sliding movement in position. Furthermore, it is possible to use fiber layers, which permanently cover openings and thus prevents ingress of water.

Special membranes or microfibers, which are intended to protect ventilation openings against the ingress of water and foreign bodies, hinder considerable air circulation and thus a removal of used air or water vapor. The use of special membranes are mostly laboratory versions that only allow water vapor molecules to pass through and, in most cases, do not bring any tangible success. In addition, materials of this type have the disadvantage that they are permeable only on one side, that is, if water vapor is to penetrate to the outside, it is not possible that outside air penetrates inwards due to the nature of the material, namely the orientation of the capillaries.

To improve comfort, for example, shoes are also partially equipped with ventilation options. The ventilation in previously known ventilated shoes is essentially by the use of open-pore materials, microfibers or vents.

Some types of shoes have openings in the area of the upper part of the shoe which are in part connected with structures, for example lamellae, which allow improved supply of outside air or outward penetration of water vapor. Other shoes have openings in the soles of the shoes. In order to prevent ingress of water and foreign bodies, these openings are covered for example with a special membrane or a microfiber, which is associated with the disadvantages already described.

Mechanical ventilated shoes help ventilate the shoe interior with kinetic energy. Some of these solutions sometimes use quite complex mechanical internal structures. Mechanical ventilation systems inside shoes have proven to be quite vulnerable, expensive and thus expensive to manufacture. In addition, it is disadvantageous if an air supply and a consequent reduction in the humidity in the shoe interior is only possible when the wearer is moving.

A corresponding ventilated shoe is from the European patent application EP 1 500 341 A1 known. This ventilated shoe features a footbed insert with a pump chamber at the back. Flow channels lead from the pumping chamber to the forefoot area and connect the pumping chamber to a ventilation zone in the forefoot area. The air flows from the pumping chamber through the flow channels into the forefoot area and from there into the inside of the shoe. However, a targeted removal of the used air from the shoe interior is not described.

Furthermore, it could be observed that the moisture contained in the air, which condenses out of the interior of the shoe, condenses in the interior of the sole, especially at low outside temperatures, where it leads to water retention. which favor an increase of bacteria and mold spores and a concomitant odor. In order to prevent the penetration of water and dirt in ventilated shoes, so far, a compromise between comfort and function must be considered.

• Wasser kann eindringen,
• kein tatsächlich spürbarer Erfolg hinsichtlich der Belüftung oder
• manueller Schutz vor dem Eindringen von Flüssigkeiten notwendig.

These aforementioned solutions of the ventilation openings thus have the following disadvantages:

• Water can penetrate,
• no real noticeable success in terms of ventilation or
• manual protection against the ingress of liquids necessary.

In order to prevent the penetration of water into textile surfaces, the use of a polymer, so-called superabsorbers, coated or impregnated fibers is already known. These absorbers, which are connected to the fiber, swell on contact with water and, due to the fluid-related increase in volume, interspaces which are located between the fibers seal off. Corresponding textile materials are eg in DE 1 444 056 A1 disclosed. Also from the DE 3 244 386 A1 is a moisture-absorbing substance is known, which provides especially in the interior of protective suits for a more comfortable wear climate in which it absorbs body moisture.

The use of superabsorbers in textile surfaces proves to be disadvantageous because corresponding textiles are fully saturated with water or moisture over the entire surface, correspondingly increase in weight and often have an unpleasant, jelly-like consistency. Moreover, there is the disadvantage that superabsorbers in the previous materials can not permanently be connected to textile fibers so that the materials are permeable to air in the dry state, but in conjunction with water to form a waterproof layer, which is again permeable to air after drying.

Known fiber layers with superabsorbers that absorb moisture have the disadvantage that they are only permeable to air through their relatively high density and material thickness to a very reduced extent, in addition they can because of their capillaries Water to surrounding materials with which they are in contact forward (moisture bridge). Furthermore, they will take a long time to dry again; which can lead to mold and bacteria formation and a resulting odor.

The invention is an object of the invention to provide ventilation inserts that are highly air or wind permeable, prevent foreign bodies, automatically close in the wet / rain, the ambient air moisture to escape, prevent ingress of water and automatically in drought open again to allow ventilation. It is also an object of the invention to provide a ventilated shoe which extracts moisture from the interior of the shoe, undesirable accumulations of condensation, e.g. Foot sweat in the shoe interior, avoids, and thus prevents the proliferation of odor-causing bacteria or germs. In this case, such ventilation inserts or ventilation systems for shoes in a structurally simple manner, can be produced inexpensively and from health-friendly materials. The ventilation and dehumidification of the shoe interior should also be possible regardless of a movement of the foot.

• einer Schicht B mit einem quellbaren Material, wie einem Absorber,
• einer zweiten offenporigen luftdurchlässigen, wasser- und/oder wasserdampfdurchlässigen Fläche C

Die Distanzfläche kann den Textilien bzw. Schuhinnenrum zugewandt sein oder kann zum Schutz vor beispielsweise mechanischen Belastungen auf der Außenseite des Belüftungseinsatzes angeordnet sein.

An inventive ventilation insert is at least constructed

• an open-pore, air-permeable, water- and / or water vapor-permeable surface A,
• a layer B with a swellable material, such as an absorber,
• a second open-pore air-permeable, water and / or water vapor permeable surface C
• and possibly a distance surface. The ventilation insert according to the invention is preferably partially covered at its edges by the material of the shoe upper or that of the outsole. The spacer surface may be facing the textiles or shoe inner or may be arranged on the outside of the ventilation insert for protection against, for example, mechanical stresses.

The layers of the ventilation insert are possibly through connecting devices which penetrate the ventilation insert, such as. As seams, adhesive surfaces, thermoplastic welding, at the time of manufacture flowable materials, Pfalzverbindungen firmly connected. The connecting devices preferably form punctiform or strip-shaped elevations on the upper and / or lower sides of a ventilation insert according to the invention and, due to their configuration, optionally serve as spacer surfaces. Preferably, the layers of the ventilation insert according to the invention are interconnected so that the absorber contained in the ventilation insert is also on the sides of a ventilation insert according to the invention is captive, ie can not escape from the ventilation insert. Especially preferred the layers of the ventilation insert are formed and interconnected such that the absorber contained in the ventilation insert due to eg reversible swelling caused by water and the associated increase in volume, hindered in its expansion or this is so much limited that the swellable material from the the absorber consists at least in part, compressed so that the ventilation insert forms a water-repellent surface, or seal the air-permeable gaps.

Preferably, the layers of a ventilation insert according to the invention are connected by connecting devices which fix the layers of a ventilation insert according to the invention in a fixed distance from each other so that the absorber contained in the ventilation insert is protected from a strong compression. Compressions, such as caused by shocks, therefore, do not lead to leakage of the swollen portion of the absorber from the ventilation insert.

The ventilation insert is provided by connection possibilities e.g. by: gluing, plug-in connections, partial enveloping, with materials that are flowable at the time of production, sewing, thermoplastic welding, fastened over the material openings to be closed or openings in the shoe upper and / or the outsole in a desired position. Material projections, which may be formed as structures which are located on the ventilation insert or are part of the ventilation insert, support a fastening in the desired position.

The ventilation insert preferably has connection options that allow replacement / removal of the ventilation insert, as they are known about connectors.

The ventilation insert is preferred by typical connectivity to its, formed as a material projections structures by means of, for example, adhesive surfaces, seams, thermoplastic fusion or turnover, wrapping with at the time of production flowable materials, with the material of the shoe upper, the Outsole and / or textiles. The connection options are chosen so that they form an at least water-repellent surface or are waterproof.

The permeable surfaces A and C are preferably made of an open-pored layer such as e.g. Tissues or surfaces which have perforations / openings. For example, the permeable surface A or C is composed of natural fibers such as wool, polymer composites, glass composites, carbon compounds, open cell ceramic surfaces, metal fabrics, metal surfaces having a plurality of apertures, mineral fibers, and composite materials composed of blends consist of the aforementioned materials. The permeable area C can at the same time form the distance surface, e.g. by being designed as a relatively "thick" perforated surface, which is preferably made of a flexible material, e.g. a polymer mixture.

The distance surface is permeable to water vapor and air due to its open-pored nature. The spacer surface is in one embodiment the same part as the water vapor / water permeable surface, if e.g. was produced as injection molding. It is possible to arrange a spacer surface on each of the outer surfaces of a ventilation insert. The distance surface may e.g. be formed by turning the surface, both as upper, lower and / or side part. In a further embodiment, the spacer surface is designed as a protective grid. The protective grille prevents damage to the open-pore, air-permeable, water- and / or water vapor-permeable surface adjoining the spacer surface. Preferably, the protective grid is made by injection molding and is arranged on the outwardly facing side of the ventilation insert.

In one embodiment, the distance surface and the water vapor / water-permeable surface is made as a sleeve element, inside which there is an absorber. The sleeve element may, for example, have the shape of a raw possibly a square tube. This embodiment has the advantage that even with strong swelling of the absorber material gives a higher mechanical stability of the ventilation insert is. For the application area with a high moisture content, a configuration in a sleeve shape is accordingly preferred, since even with very strong swelling of the absorber, there is a risk that it will swell so much that it causes the delimiting, open-pored, air-permeable, water- and / or water vapor-permeable surfaces A resp C damaged. The sleeve element is for example designed so that the surface A forms an outer shell, in which the absorber layer B is arranged and this is bounded inwardly by a second surface C, which is also formed sleeve-shaped. The sleeve may optionally be surrounded by a spacer surface on the outside.

The ventilation insert is characterized by typical connection possibilities, such as e.g. Adhesive surfaces, stitching, thermoplastic fusion, by partially enclosing flowable materials at the time of manufacture or handling with the material of the shoe upper, the outsole, connected. From the material of the ventilation insert e.g. Structures formed as material projections structures of connecting devices according to the invention and / or permeable surfaces and / or filling materials enable / support a fastening with the material of a shoe upper and / or an outsole. The connection options are chosen so that they allow waterproofness or water repellency.

The spacer surface serves as a barrier to any moisture bridge that may occur and resulting water / moisture transfer to materials in contact with the ventilation insert, such as the inner material of a shoe of the present invention, stockings, overlying pant legs, etc. Distance surface by their material protrusions or bulges as protection against any damage to the water / water vapor permeable surface.

The absorber element preferably has a carrier material or a filling material onto which an absorber, ie a swellable material, such as, for example, cross-linked sodium polyacrylate, proteins or casein, has been applied or is in contact therewith. According to the invention, the spaces formed by the filling material, filled with a water-induced swelling of the absorber and so closed. The filler reduces the amount of absorber needed for a given volume. A preferred filling material is, for example, cork, animal hair, polymer compounds, rubber, glass or ceramics.

As a further preferred absorber, water-swellable polymer plastics, so-called superabsorbents, are used, e.g. a thermoplastic elastomer composite or crosslinked polyacrylic acid derivatives. These are due to their shape, design and composition, e.g. as threads, granules, powders, are reversibly swellable within a short time, increase in volume, as well as dry quickly and reduce the volume.

Possibly. This process is made visible by a color change of a hydrochromatic dye, which is in contact with the ventilation insert, and thus signal when a ventilation insert according to the invention is waterproof or permeable to air. For this process, the absorber is additionally provided with hydrochromic and / or thermochromic dyes in a particular embodiment.

In one embodiment, the absorber is provided with a microbicidal agent which inhibits the proliferation of microorganisms, i. Germs, bacteria or fungi and the resulting odor formation is reduced or prevented.

Surprisingly, it is thus possible through the ventilation insert according to the invention to ventilate both textiles, headgear and shoes effectively, with a noticeable ventilation is noticeable. The ventilation insert according to the invention advantageously allows the closure of ventilation openings, without manual protection against the ingress of liquids is necessary because the swelling of the absorber effective protection against the ingress of water is shown. Since the moisture contained in garments or shoes is also collected by the absorber, the formation of condensation is avoided and thereby also the proliferation of bacteria and mold spores is suppressed.

This effect makes it particularly advantageous to observe when the absorber is additionally equipped with microbiocide.

The ventilation insert according to the invention is preferably used for ventilation on the top in textiles, headgear or shoes. The ventilation insert is used for example in jackets, trousers, gloves, backpacks, bags, protective helmets, goggles, headgear, tents and protective work clothing, as well as children's shoes, sports shoes, work shoes or hiking boots. When used in protective helmets, the ventilation insert also serves as an air filter e.g. ais pollen filter to improve air quality.

The invention also provides a ventilated shoe with an outsole, an insole arranged above it, an insole disposed above, a shoe upper connected to the outsole with ventilation openings, characterized in that the outsole has a cavity at least in the heel region, wherein the cavity has a cavity Has outlet opening and the cavity is connected via air inlet openings in the insole with a space between the insole and the insole and the insole is connected at least in the front area via air inlet openings with the shoe interior.

In a particular embodiment, the ventilated shoe between the insole and the insole spacers, which are preferably formed depending on the design strip, triangular or punk-shaped. The spacers ensure that airflow is always possible between the insole and the insole and that the insole is not pressed by the weight of the wearer onto the insole in such a way that both the air intakes in the insole and the air intakes in the insole are closed.

During movement, air is forced out of the cavity in the heel area through the outlet opening by exposing the heel. During further movement, a negative pressure is created in this now empty cavity, whereby air via the air inlet openings from the space between the insole and insole in the cavity is sucked. This in turn leads to a negative pressure in the intermediate space and it is sucked through the air inlet openings in the front foot area spent air from the inside of the shoe. At the same time fresh air can flow through the ventilation openings in the shoe upper back into the shoe interior. As a result, effective ventilation is ensured, in particular the used air is transported away from the interior of the shoe.

The further properties of the individual parts of the shoe will be explained in more detail below, wherein these may be configured in the same way as in the shoe according to the invention with ventilation insert described below.

The invention furthermore relates to a ventilated shoe with an outsole, an insole arranged above it, an insole disposed above, a shoe upper connected to the outsole and ventilation openings with a ventilation insert which is arranged in front of or in the ventilation openings, characterized in that the ventilation insert has at least one absorber element.

Material breakthroughs, which may be formed from the material of the shoe upper and / or parts of the outsole, are preferably closed by a ventilation insert according to the invention, which has a multilayer structure. Preferably, the ventilation insert of the ventilated shoe is composed of at least the following layers:

• a layer A, which is formed by an open-pore, water-permeable and water-vapor-permeable surface,
• an absorber layer B which immediately adjoins it and which is formed at least partially from a swellable material, such as an absorber, and optionally additionally contains filling material,
• a layer C, which is formed by a water vapor and air permeable surface, as well as
• if necessary, a distance surface facing the shoe interior and / or the shoe outer side,
• wherein the layer A and the layer C each directly adjacent to the absorber layer B and limit this.

The surfaces A, B and C and the spacer surface correspond in their design to the above-described surfaces of the ventilation insert according to the invention.

The inventive shoe with ventilation insert has an outsole, with at least one cavity which is formed by a material recess in the outsole. The cavities in the outsole are preferably in the area of the forefoot and / or the heel. The formed from the outsole cavities and possibly existing air ducts are closed by the insole, which is arranged above the possibly multi-layered outsole. The insole has preferably in the region of the cavity of the outsole on material breakthroughs in the form of the foot interior facing air inlet openings or outlet openings. The openings are in communication with the cavity: Located above the outsole and connected to this and to the insole, there is a shoe upper. The shoe upper preferably has ventilation inserts.

Within the shoe according to the invention is located above the insole arranged an insole, which is preferably anatomically shaped and constructed of a skin-friendly breathable material. The insole has at least at the height of the heel, and preferably in the area of the forefoot, material breakthroughs, which at least one connection between the shoe interior and the cavity, which may be located in the fore and / or hindfoot area through the insole. The material breakthroughs that are located within an insole may be e.g. consist of integrated textile molded inserts. These material breakthroughs of the insole serve to transport air and can be configured as air inlet openings and / or outlet openings.

Furthermore, the insole is preferably formed in places, particularly preferably at the level of the air inlet openings and / or outlet openings as bulges, which prevent a permanent closing of the openings, as well as due to their cavity The insole and / or the insole preferably has spacers, at least in regions of the air inlet openings, which are designed to be striped or punctiform depending on the design. Preferably, the air inlet openings of the insole are at the same height as the openings of the insole. The spacers prevent closing of the outlet openings caused by a force effect.

In areas of the air inlet openings of the insole, insole and outsole are particularly preferably connecting devices that connects the superimposed surfaces together so that an air flow through the superimposed air inlet openings is favored. The insole and / or insole may preferably have on its underside connecting means, e.g. strip-shaped adhesive surfaces which seal an air duct and / or an air inlet opening at its / its edges so that an air flow is limited at their sides.

In one embodiment, at least one absorber element or ventilation insert is arranged in the cavities of the outsole. For the positioning of the absorber element, a recess is preferably provided within the cavity, whose side walls are preferably formed outwardly at an increasing angle. The recess may be e.g. be formed or have devices that an absorber element is fixed in position. A connection between the cavity and the outside air is made through an exit opening in the outsole and / or insole. The exit port is an air entry port, i. it allows air through in one direction only and is preferably provided with a valve.

In a preferred embodiment are located within a cavity and / or depression damping inserts, which absorb and re-cushion due to their flexible material properties, such as shocks, as well as press down the air inlet openings inside the insole air impermeable. The damping inserts preferably have on their, the Insole facing surfaces, structures such as strips or point-like bulges or bulges, which prevent a force-independent closing of the air inlet openings.

In one embodiment, the shoe has at least two interconnected cavities in the outsole. The cavities are interconnected by an air duct, wherein more preferably the cavity is connected to the air duct via at least one passage openings. In a particularly preferred manner, the passage openings, which are soft components of the cavities and / or the depression, are connected to one another by air ducts. The air duct may preferably be formed of material recesses which are located in the outsole, or depressions or bulges of the insole and / or the insole. Alternatively, the air duct may be formed of a combination of opposed strip-shaped inlets and bulges / material recesses, which are located both on the insole, as well as on an insole.

Within the air duct is preferably a closure, which is formed by opposite bulges. Due to their structure, the inner walls of the air duct are preferably designed as a closure dependent on a force effect. The closure of the air duct is possibly as a one-way air passage opening such. B. formed a valve. If necessary, an absorber element is located inside the air duct.

Ingress of dirt, dust or water into the Lufteinwegsöffnung and a resulting inoperability and thus a reduction in air circulation is preferably prevented by a cover which was placed from the outside and / or inside. An air-permeable cover is made for example of a fine-pored material, which is preferably equipped with a dye, such as a thermo and / or a hydrochromic dye. Alternatively, the cover is designed as a polymer molding, which has on its surface over a distance surface, which due to their bulges or texture protection against damage Offer. Preferably, the air-permeable covers are arranged on the air inlet openings or outlet openings to prevent accumulation of dirt or dust inside a cavity or an air duct.

By transparent components, e.g. Viewing windows in the outsole and / or the insole and / or the insole can be made visible from the outside moisture and / or heat-related discoloration of the absorber, as they arise when using hydrochromer- / thermochromic dyes.

Surprisingly, the shoe according to the invention allows effective ventilation of the footwear, without the moisture from the outside can penetrate into the shoe. In addition, a significant improvement in the moisture formed in the shoe can be observed:

Due to high air humidity consumed air from the inside of the shoe, as it arises especially during sports activities by sweating on the foot surfaces, condensation can form inside the cavity and possibly within the air duct, especially at low outside temperatures. This accumulates both by the air currents, as well as by different angles of inclination, as they typically arise when moving or wearing a shoe within the cavity, possibly in the recess where it is received and held by an absorber element. In weather or environmental conditions with lower humidity, such as especially within buildings, or higher temperatures or lower levels of physical activity and a reduced perspiration from the previously recorded condensate evaporates due to constant air circulation within the cavity. By the absorber element at the same time a drop to the outside or a delivery to the insole or to the shoe interior is prevented. Bacterial or odor formation is thus effectively avoided.

The shoe upper of a shoe according to the invention consists of the materials typical for this purpose, such as, for example, leather, fiber blends, synthetic leather, rubber, polymer composites or mixtures / combinations thereof. The attachment of the outsole and the insole to the shoe upper takes place according to the various prior art known in the field of shoe technology, e.g. through seams, partial coverings with materials that are flowable at the time of manufacture, gluing, forming etc ..

The outsole is, for example, cast or extruded ester base polyurethane film having a Shore "A" hardness of 80 to 95, such as Tetra Plastics TPW-250, which is coated with hexafluoroethane, e.g. Dupont F-116 or sulfur hexafluoride is inflated, or ethylene vinyl acetate (EVA) produced.

A particularly preferred embodiment of the insole provides that it consists of an elastic, resilient material. The insole is e.g. anatomically shaped and consists of a skin-friendly breathable material.

According to the invention, it is possible that the spacers consist of a material independent of the insole, insole and the outsole. Spacers may, for example, be made of at least one elastic molded part which is defined by e.g. Adhesive surfaces, seams, thermoplastic fusing or by partially enclosing at the time of manufacture flowable materials in a designated position fastener be prepared. The spacers may e.g. cast or extruded Esterbasen polyurethane film, having a Shore "A" hardness of 30 to 80 or have this.

The damping inserts in the cavities of the outsole are preferably made of an elastic material which has impact-absorbing properties and is typically used in this application, such as rubber, foamed polymer compounds or gas-filled or gel-filled elastic bladders. The damping insert prevents permanent or excessive flattening or compression of the cavities. In addition, it allows a recording and cushioning of strong forces, such as impacts, such as those that occur when jumping with a shoe.

The cover is preferably made of a fine-pored air-permeable material that is optionally equipped with a thermo and / or a hydrochromic dye. Exposed covers according to the invention may e.g. consist of a polymer molding, which at its surfaces over e.g. Lattice striped pimple-shaped spacer surfaces, the protection of the fine-pored air-permeable surface of the cover against damage such. offer sharp or sharp objects. Optionally, the spacer surfaces may be formed from structures of the cover.

In the embodiment of the ventilated shoe with a cavity in the forefoot area, which is connected to the cavity in the heel via a Luftführungsanal, the ventilation during the movement of the shoe is described as follows: By a force, as typically occurs when putting on the foot , the air inlet openings of the insole, as well as the insole and located at the level of the air inlet openings damping inserts are pressed and so closed. The connection between the shoe interior and the cavity is thus interrupted. The cavity, e.g. in the heel area of the outsole is compressed. The air contained in the cavity is pressed through a passage opening in the adjacent air duct and through a further passage opening in a second lying in the forefoot cavity.

By further lowering the foot, the bulges of material of the inner side walls of the air duct move towards each other until they touch and seal the air duct as a closure. Due to the further rolling movement / weight bearing by z. B. a foot remains closed the closure in the air duct. The air previously pressed into the cavity located in the forefoot region is compressed by pressing on the surface, for example that of the foot / by a weight such as a body weight, and the air inlet openings of the insole are sealed against the escape of air into the interior of the shoe.

The air is forced through parts of the absorber element in the cavity and through the cover through the outlet opening to the outside. It creates a negative pressure in the shoe interior. The outside air flows through ventilation inserts, which are located inside the shoe upper or the outsole in the shoe interior. A breeze is created inside the shoe. Possible impurities / foreign bodies such as e.g. Dust / pollen and liquids, such as rain, are blocked or filtered out of the layers of the ventilation insert.

By removing a force, e.g. when lifting the foot, the air inlet openings, which are located one above the other inside the insole, the insole and a cavity release. Between air inlet openings and the filling material creates a gap. The cavities, which are located in the forefoot area, as well as in the rear foot area, as well as the air duct stretch. A negative pressure within the cavities and the air duct occurs. The shutter inside the air duct opens. Since the outlet opening has a one-way air outlet opening, or their total area is smaller than the sum of the area of the air inlet openings, primarily consumed air flows from the inside of the shoe into the cavities and the air duct. When re-sweeping the foot repeats the air circulation described above.

The shoe according to the invention allows an improved air exchange between the shoe interior and the ambient air, driven by the kinetic energy, as typically arises when running. In addition, surprisingly, the ventilation is independent of the movement possible, the air vents used in this case automatically close against water and automatically reopen in case of drought and thus prevent the penetration of moisture into the shoe interior.

The invention further relates to an insert with ventilation device for a shoe, which serves to ventilate the shoe. The insert is made of two elastic molded parts manufactured and combines the located in the sole ventilation device in a single possibly replaceable component. The elastic molded parts have connecting devices. The insert may be designed to either pump spent air out of the shoe interior or fresh air into the interior of the shoe. The insert is in contact with the insole and / or outsole and / or insole and is preferably connected to the outsole and / or the insole and / or the insole and the air ducts so that it is exchangeable or replaceable. Particularly preferably, the use is connected by releasable adhesive surfaces, plug-in or Velcro connections. The insert is preferably fixed by connecting devices in a desired position.

Depending on the positioning of the air outlet openings in the insert air ducts allow air flow into desired areas of the shoe, the connecting devices allow a fluid-tight connection with air ducts.

An elastic compensating surface in use prevents force caused by e.g. by pressing with an insole close the outlet openings. The elastic compensation surface consists e.g. cast or extruded ester-base polyurethane film, having a shore "A" hardness of 30 to 80, or other elastic material. The compensation surface is provided by connection possibilities, e.g. by: gluing, plug-in connections, sewing, thermoplastic welding, wrapping with materials which are flowable at the time of manufacture, fixed on the top and / or bottom of the molding in a desired position. The compensation surface is possibly part of the elastic molding and / or the fire and / or insole.

The insert according to the invention has on its top and bottom elastic molded parts which are interconnected via the connecting devices. In one embodiment are in the region of the air inlet openings are also concavities, which are preferably formed from the material of the elastic molding. The indentations prevent the insole when force is applied permanently bonded to the elastic molding and possibly closes the outlet openings. From the insert out lead two air ducts at the end of which is an air outlet opening.

The insert according to the invention with ventilation device has damping stoppers in the interior, between which an absorber element with absorbers embedded therein is placed. The interior of the insert is formed by a cavity. The damping inserts are preferably not arranged in the region of the air inlet openings.

In a further embodiment of the insert with ventilation device are in the elastic molding air outlet openings, which are preferably arranged centrally in the insert between the compensation surface. Out of the insert leads at least one air duct, at the end of which is an air inlet opening.

Above the elastic molding, a compensation surface is preferably attached. The compensation surface extends over parts of the surface of the upper elastic molding. Only in the region of the air outlet opening no molding is arranged. The insert may possibly be connected to the shoe via material projections.

The location information, such as top, bottom, side, center, etc. are each relative to each other. With reference to the shoe means down to the ground or directed to the sole and directed to the top of the shoe wearer or to the shoe top.

The connection of the ventilation insert 4 with the shoe upper part 9 takes place via connecting devices 5. The ventilation insert is in turn formed from the permeable surface 6a with the adjoining absorber element 22 with absorber 14 of the final permeable surface 6b. The connecting devices 5 also hold the layers of the absorber together and form the spacer surface at their tips.

FIG. 3 a shows a side view of the ventilation insert from FIG. 2, wherein in particular the absorber surface 8 formed by the connecting elements 5 can be clearly seen.

FIG. 3b shows a further embodiment of the ventilation insert in which it is connected at its edges only above with the material of a shoe upper 9. The connecting devices 5 serve both for fastening the ventilation insert on the shoe upper 9, as well as for connecting the individual layers of the ventilation insert with each other.

Figure 4a shows an embodiment of the ventilation insert according to the invention as a sleeve member. In this case, the outer shell of the sleeve member is formed by a permeable surface 6a, to which the absorber element 22 is connected to the absorber 14 disposed therein. To the sleeve interior, the absorber element is closed by a likewise sleeve-shaped permeable surface 6b. The sleeve may be surrounded by a spacer surface 8, which is not shown here. The moisture-containing air penetrates through the surface 6a in the sleeve member and is transported out along the arrows from the sleeve member.

FIG. 4b shows a further embodiment of the ventilation insert according to the invention as a sleeve element. In the front region of the sleeve member connecting devices 5 can be seen, which connect the sleeve member like a funnel with the textile or the shoe.

Figure 5 shows a shoe according to the invention of an outsole 1 and an associated shoe upper part 9. In the outsole are cavities 11a and 11b, which are connected via an air duct 13. Above the outsole, an insole 2 is arranged, which closes the cavities 11a and 11b upwards. In the insole are several air inlet openings 17a through which the cavities in the outsole are connected to the interior of the shoe. The insole 2 also has spacers 10, which are formed hemispherical here. The sole structure is closed to the shoe interior by the insole 3, which is arranged above the insole 2. In the insole 3 are also a plurality of air inlet openings 17b, which are configured as material breakthroughs. In the shoe upper 9 is located in the front foot area a ventilation insert 4, in which the connecting devices 5 can be seen connecting the various layers of the ventilation insert together.

FIG. 6 shows a sectional drawing through the outsole 1 and the insole 2 of the ventilated shoe shown in FIG. The outsole has the cavity 11a in the rear region and the cavity 11b in the front region. Within the cavity 11a, a recess 18 is provided, whose side walls are formed outwardly at an increasing angle. In the recess 18, an absorber 14 is placed, which is additionally mixed with filling material. Within the recess 18 two columnar damping inserts 21 are further arranged. The damping inserts are arranged below the air inlet openings 17a of the insole 2. In the front cavity 11b is also a recess 18b can be seen, in which two damping inserts 21 are arranged. For the positioning of an absorber 14, a recess 18 is provided within the cavity 11, the side walls are preferably formed outwardly at an increasing angle. In the recess 18, an absorber element 14 is positioned.

A connection between the cavity 11 b and the outside air is established through the outlet opening 16. The outlet opening 16 is provided with a cover 15 which is intended to prevent the ingress of dirt, dust or water. The rear cavity 11 a and the front cavity 11 b are connected via the air duct 13. The access to the air duct 13 leads at the beginning and end through openings 20. The inner walls of the air duct 13 are formed as a dependent of a force closure 12. The formed from the outsole 1 cavities 11 and air ducts 13 are closed by the insole 2.

In Figure 7, the outsole on two cavities 11a and 11b, which are connected to each other via the air duct 13. In this embodiment of the shoe, the air inlet openings 17a of the insole 2 are offset from the air inlet openings 17b of the insole 3.

FIG. 8 shows a further embodiment of the shoe according to the invention. In this case, the cavity 11a in the rear shoe area and the cavity 11b are not connected to each other. The cavity 11 a has for this outlet openings 16, which are provided with covers 15.

FIG. 9 shows by way of example how the air flow takes place inside the shoe from FIG. 5. When an impact force, as typically occurs when putting on the foot, the insole 3 and the insole 2 is charged, the air inlet openings 17a and 17b close. At the same time, the cavity 11a is compressed and the air contained therein is pressed through a passage opening 20 in the air duct 13 and then through a further passage opening 20 in the fore-foot cavity 11b along the arrows b. As a result of the further lowering of the foot, the bulges 12 of material move toward one another until they touch and, like a closure, seal the air duct 13. Due to the rolling movement, the air inlet openings 17b of the insole 3 and the air inlet openings 17a of the insole 2 are pressed onto the damping inserts 21 and thus closed. The air is now pressed through parts of the absorber 14 and through the cover 15 through the outlet openings 16 through to the outside, along the arrows c. It creates a negative pressure in the shoe interior.

Through the ventilation inserts 4 in the shoe upper 9 air flows along the arrows d air in the shoe interior. When lifting the foot, the air inlet openings 17a and 17b, which are located one above the other inside the insole 3 and the insole 2, released again. The cavities 11a and 11b, and the air duct 13 stretch. Due to the negative pressure within the cavities 11a and 11b and the air duct 13, air now flows along the arrows a into the cavities 11a and 11b.

Figure 10 shows the course of the air flow for a shoe with two separate cavities 11a and 11b. By the action of force, as is typically the case during running, the air inlet openings 17a of the insole and 17b of the insole are pressed onto the damping inserts 21 and the cavities 11a and 11b are closed.

For the further force, the cavities are compressed and the air therein is conveyed through the absorber 14 and the outlet openings 16 to the outside. When raising the foot and relieving the sole creates a negative pressure in the cavities, whereby air is sucked from the shoe interior into the cavities. Due to the negative pressure occurring in the shoe, an air compensation takes place along the arrow c above the ventilation insert 4 in the shoe upper 9.

In the case of that shown in Fig. 11, the cavities 11a and 11b are also not connected to each other. Instead, the air duct 13a or 13b leads from the cavity 11a or 11b through the insole 2 to the interior of the shoe. In the insole 2 are air outlet openings 16 while in this case the air inlet openings 17 are located within the cavities 11 in the outsole 1. Between the insole 3 and the insole 2 spacers 10 are arranged below the insole 3, which prevent the outlet openings can close by force. The damping inserts 21 are each arranged as far as possible at the edge of the cavities 11a and 11b.

FIG. 12 shows the course of air when the shoe is used according to FIG. 11. The used air from inside the shoe flows outward along the arrows c through the ventilation insert 4. Due to the negative pressure arising in the shoe, fresh air is transported along the arrows a through the air inlet opening 17 into the cavities 11a and 11b. These pass along the arrows b via the air ducts 13 through the air outlet openings 16 in the shoe interior. The spacers 10 prevent closure of the outlet openings 16 caused by a force effect.

13 shows a longitudinal section through a further embodiment of a ventilated shoe according to the invention without ventilation inserts. The shoe has an outsole 1, an insole 2 arranged above it and an insole 3 arranged above the insole. The outsole 1 is connected to a shoe upper 9 with ventilation opening 4. In the heel region of the outsole 1, a cavity 11 is arranged, which has an outlet opening 16 and air inlet openings 17a in the insole 2 with a gap between the insole 2 and the insole 3 is connected. The insole is at least in the front region via air inlet openings 17b connected to the shoe interior.

During the movement, air is forced out of the cavity 11 in the heel region through the outlet opening 16 along the arrow a by exposing the heel. In the further movement, a negative pressure in the cavity 11, whereby air is sucked through the air inlet openings 17a from the space between the insole and insole into the cavity. Exhausted air from the inside of the shoe flows along the arrows b via the air inlet openings in the front foot area. Via the ventilation opening 4 in the shoe upper 9, the air inside the shoe is replaced (arrow c).

Figure 14a shows a plan view of an insert with ventilation devices. The insert has on its top and bottom elastic molded parts 24 which are connected to each other via the connecting devices 5. In the area of the air inlet openings 17 are also concavities 23, which are formed here of the material of the elastic molding 24. The indentations 23 prevent the insole 3 from permanently sticking to the elastic molded part 24 when the force is applied and, if necessary, closing the outlet openings. From the insert lead two air ducts 13, at the end of which an air outlet opening 16 is located.

FIG. 14b shows a section of the insert with ventilation device from FIG. 14a. Here it can be seen that damping inserts 21 are located inside the insert, between which an absorber element 22 with absorber 14 embedded therein is placed. The interior of the insert is formed by a cavity 11. The damping inserts 21 are not arranged here in the region of the air inlet openings 17.

Figure 15a shows a further embodiment of the insert with ventilation device in a plan view. Above the elastic molding 24 while a compensation surface 25 is attached. In this insert 24 air outlet openings 16 are located in the elastic molded part, which are arranged centrally in use between the compensation surface 24 are. From the insert leads an air duct 13, at the end of which an air inlet opening 17 is located.

FIG. 15b shows a section through the insert from FIG. 15a. It can be seen that the compensation surface 25 extends over the entire surface of the upper elastic molding. Only in the region of the air outlet opening 16 no molding is arranged. The insert can be connected via material projections 19 with the shoe.
