Abstract

A shoe sole or insole has an active agent-containing sorbent fiber interlayer sandwiched between an upper diffusion layer and an underlayer. An Independent claim is also included for production of the above sole structure.

Description

Die Erfindung betrifft einen Sohlenaufbau für einen Schuh oder eine Einlegsohle mit drei Schichten eine obere diffusionsoffene Schicht sowie eine davon beabstandete untere Schicht vorhanden sind und zwischen diesen beiden Schichten eine Zwischenschicht mit saugfähigen Fasern eingebracht ist, die mit zumindest einem Wirkstoff beaufschlagt ist.The invention relates to a sole structure for one Shoe or an insole with three layers one upper layer open to diffusion and a spaced apart lower layer are present and between an intermediate layer between these two layers is introduced with absorbent fibers, which with at least an active ingredient is applied.

Unter Sohlenaufbau wird im Sinne der Erfindung der unter der Fußsohle des Benutzers befindliche Teil des Schuhs verstanden, der auch als Einlegesohle ausgebildet sein kann. Füße von Menschen, insbesondere deren Sohlen, sind Köperteile, die zu einer hohen Schweißabgabe neigen. Dies ist insbesondere deshalb problematisch, weil die Füße oft stundenlang in Schuhe eingebettet sind, die im Gegensatz zu anderen Kleidungsstücken für eine intensive Reinigung nur schwer zugänglich sind, mit der Folge, daß dort teilweise eine erhebliche Geruchsentwicklung entsteht. Da Schuhe zudem so ausgelegt sind, daß sie das Eindringen von Nässe verhindern, ist es kaum verwunderlich, daß ein Abtransport der durch Transpiration der Füße entstehenden Feuchtigkeit nur langsam vor sich geht. Das Innere von Schuhen ist daher häufig feucht, so daß dort eine Atmosphäre entstehen kann, in der sich Bakterien und Pilze gut vermehren. Verletzungen an Füßen, wie beispielsweise Blasen, heilen in einem derartigen Umfeld nur langsam. Under sole construction in the sense of the invention Part located under the sole of the user's foot of the shoe understood as the insole can be trained. Feet of people, in particular their soles are body parts that lead to a tend to have high levels of sweat. This is particularly so problematic because the feet often last for hours are embedded in shoes that contrast to other items of clothing for intensive cleaning are difficult to access, with the result that there is in some cases a considerable development of smell arises. Since shoes are also designed it is that they prevent the ingress of moisture It is hardly surprising that the removal by Perspiration of the feet arising moisture is going on slowly. The inside of shoes is therefore often moist, so that there is an atmosphere can arise in which bacteria and Multiply mushrooms well. Foot injuries like for example blisters, heal in such Environment slowly.

Zur Lösung dieses Problems sind Einlegesohlen bekannt, die die Feuchtigkeit aufnehmen und zum Teil auch mit antibakteriellen Mitteln und Duftstoffen versehen sind. In der europäischen Patentanmeldung EP 0 693 259 A2 ist eine Sohlenanordnung beschrieben, in der einzelne Teile der Sohle, etwa da gelegen, wo sich die meisten Schweißdrüsen am Fuß befinden, ausgewechselt werden können. Auch diese auswechselbaren Elemente haben die bekannten Vorteile der Einlegesohlen. Aus der EP 0 272 690, die als Gattung angesehen wird, ist der im Oberbegriff genannte, dreischichtige Sohlenaufbau bekannt, dessen Zwischenschicht mit Wirkstoff getränkt ist. Bisher ist es jedoch nicht gelungen einen formstabilen Sohlenaufbau hinreichender Diffusionsoffenheit herzustellen.To solve this problem, insoles are known which absorb the moisture and partly also with antibacterial agents and fragrances are provided. In the European patent application EP 0 693 259 A2 describes a sole arrangement, in the individual parts of the sole, for example, where most of the sweat glands are on the foot, can be replaced. This too interchangeable elements have the known advantages the insoles. From EP 0 272 690, the is regarded as a genus, that is in the generic term known, three-layer sole construction known, the Intermediate layer is soaked with active ingredient. So far, however, a dimensionally stable one has not succeeded Sole structure of sufficient diffusion openness manufacture.

Die Erfindung hat sich demgegenüber die Aufgabe gestellt, einen Sohlenaufbau zu schaffen, der die eben genannten Eigenschaften hat.In contrast, the invention has the object to create a sole structure that the has just mentioned properties.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß die untere Schicht und/oder die Zwischenschicht und/oder die obere Schicht ein Vlies ist, und einen Anteil formbaren Materials, insbesondere Schmelzfaser, enthält und die Form der Sohle, nach Verbindung der Schichten, durch thermisches Prägen hergestellt ist.According to the invention, this object is achieved by that the lower layer and / or the intermediate layer and / or the top layer is a nonwoven, and one Proportion of mouldable material, in particular melt fiber, contains and the shape of the sole, after connection of the layers, by thermal Embossing is made.

Obere und untere Schicht schützen die mit Wirkstoff versehene Zwischenschicht vor Zerstörung oder Zersetzung, machen also den Sohlenaufbau haltbar. Sie gewährleisten weiterhin eine längere Wirksamkeit, indem sie die Freisetzung der Wirkstoffe verlangsamen, und schotten die Zwischenschicht zudem gegen direkten Kontakt mit Fußsohle oder Schuh ab. Aufgrund der Saugfähigkeit ist die Zwischenschicht imstande, erhebliche Mengen der Wirkstoffe zu speichern, zumindest in flüssiger Form, und die im Schuh entstehende Feuchtigkeit zumindest teilweise zu binden. Die Schichtung ermöglicht eine gezielte Positionierung der Wirkstoffe im Sohlenaufbau, wo sie in konzentrierter Form eingebracht werden können, so daß sich ein leichter Sohlenaufbau verwirklichen läßt. Durch die diffusionsoffene obere Schicht hindurch werden die Wirkstoffe freigesetzt, und zudem kann Feuchtigkeit, die sich in der Zwischenschicht oder unteren Schicht befindet, während des Trocknungsprozeßes entweichen.The top and bottom layers protect those with active ingredient provided intermediate layer against destruction or decomposition, so make the sole construction durable. she continue to ensure a longer effectiveness, by slowing the release of the active ingredients, and also seal the intermediate layer against direct contact with the sole of the foot or shoe. by virtue of the absorbency of the intermediate layer is capable of to store significant amounts of the active ingredients, at least in liquid form, and the im Shoe moisture at least partially to tie. The stratification enables a targeted Positioning the active ingredients in the sole structure, where they can be introduced in a concentrated form, so that a light sole construction is realized leaves. Due to the open top The active ingredients are released through the layer and moreover, moisture can accumulate in the intermediate layer or lower layer while escape the drying process.

Die obere Schicht muß diffusionsoffen sein. Diese Eigenschaft läßt sich gut verwirklichen durch ein Vlies, insbesondere aus Polyester oder Synthetik.The upper layer must be open to diffusion. This Property can be well realized through one Non-woven, in particular made of polyester or synthetic.

Auch für die untere und Zwischenschicht ist ein Vlies gut geeignet. Es muß allerdings, zumindest in der Zwischenschicht, möglichst jedoch auch in der unteren Schicht, saugfähig sein. Als Materialien empfehlen sich insbesondere Viskose, Baumwolle oder Polyamide.There is also a for the lower and intermediate layer Fleece well suited. However, at least in the intermediate layer, but if possible also in the bottom layer, be absorbent. As materials Viscose, cotton or are particularly recommended Polyamides.

Um die Formgebung und die Formbeständigkeit der Sohle mit relativ geringem Aufwand herzustellen, ist vorgeschlagen, zumindest eine der drei Schichten mit einem Anteil formbaren Materials zu versehen und gegebenenfalls später zu formen. Dazu eignen sich insbesondere Schmelzfasern. Der Sohlenaufbau läßt sich in diesem Fall thermisch prägen.To the shape and the dimensional stability of the To manufacture sole with relatively little effort, is suggested at least one of the three layers to be provided with a proportion of malleable material and to shape later if necessary. Suitable for this especially melt fibers. The sole construction can be thermally embossed in this case.

Bei Verwendung formbaren Materials in zumindest einer der Schichten, läßt sich der Sohlenaufbau auch noch nach Verbindung der Schichten miteinander formen. Damit kann die Produktion unterschiedlich geformter Sohlen weitgehend gleich gestaltet werden. Eine Lieferung der Sohlen an den Schuhhersteller ist auch in ungeformtem Zustand möglich, die Formung kann der Schuhhersteller selbst vornehmen. Dies ist mit gängigen Maschinen insbesondere dann möglich, wenn das verformbare Material eine Schmelzfaser ist.When using malleable material in at least one of the layers, the sole structure can also be even after the layers have been joined together to form. So the production can vary shaped soles are largely the same. A delivery of the soles to the shoe manufacturer is also possible in the unformed state The shoe manufacturer can carry out shaping himself. This is especially common with common machines possible if the deformable material is a Melting fiber is.

Dem erfindungsgemäßen Sohlenaufbau steht ein weiter Anwendungsbereich offen. Er kann in die Schuhsohlen integriert oder als auswechselbare Einlegesohle gebildet sein. Die Verwendung ist möglich in Straßenund Sportschuhen, aber auch in Gummistiefeln, Skischuhen oder Bergschuhen. Der Sohlenaufbau ist sowohl für Herren- als auch für Damenschuhe geeignet und kann zudem als Träger eines Fußbettes dienen.The sole structure according to the invention is another Scope open. It can be in the soles of your shoes integrated or formed as a replaceable insole his. The use is possible in streets and Sports shoes, but also in rubber boots, ski boots or hiking boots. The sole construction is Suitable for both men's and women's shoes and can also be used as a footbed carrier serve.

Sohlen von Schuhen sind, wie bereits erwähnt, häufig feucht. Dadurch entstehen ideale Bedingungen zur Vermehrung von Bakterien und Pilzen. Zur Bekämpfung schlägt die Erfindung vor, bakteriostatische, bakterizide oder auch fungizide Wirkstoffe in der Zwischenschicht einzubringen.As already mentioned, soles of shoes are common wet. This creates ideal conditions for the multiplication of bacteria and fungi. For fighting the invention proposes bacteriostatic, bactericidal or fungicidal active ingredients in of the intermediate layer.

Die Transpiration der Fußsohlen kann weiterhin zu einer unangenehmen Geruchsbildung in den Schuhsohlen beitragen. Zur Neutralisierung ist die Zwischenschicht daher vorzugsweise mit zumindest einem Duftstoff versehen.The perspiration of the soles of the feet can continue to increase an unpleasant smell in the soles of the shoes contribute. The intermediate layer is for neutralization therefore preferably with at least one Provided fragrance.

Aufgrund der saugfähigen Fasern ist die Zwischenschicht auch in der Lage, Fußnässe aufzunehmen und zu speichern, was jedoch nicht dauerhaft erfolgen sollte, da Wirkstoffe in einem feuchten Umfeld unnötig schnell ihre Wirksamkeit verlieren können. Zudem ist die Zwischenschicht bereits aufgrund der eingebrachten Wirkstoffe teilweise gesättigt, sodaß die Feuchtigkeitsaufnahme deutlich herabgesetzt ist. Um Abhilfe zu schaffen, sieht die Erfindung die Verwendung saugfähigen Materials auch in der unteren Schicht vor, an die dann Feuchtigkeit, die in der Zwischenschicht auftritt, zumindest teilweise abgegeben wird.Because of the absorbent fibers, the intermediate layer is also able to absorb foot moisture and to save, but this is not permanent should be unnecessary since active ingredients in a humid environment can quickly lose their effectiveness. In addition, the intermediate layer is already due to the introduced active ingredients partially saturated, so the moisture absorption is significantly reduced is. To remedy the situation, the invention provides the use of absorbent material also in the lower layer before which moisture then occurs in the intermediate layer, at least in part is delivered.

Obere Schicht, untere Schicht oder beide Schichten können aus Schaumstoffen bestehen, die je nach Grundmaterial und Verarbeitung Feuchtigkeit aufnehmen oder hindurchdiffundieren lassen können. Solche Materialien sind in der Regel weich und tragen sich daher angenehm. Zudem lassen sie sich gut, wie später näher erläutert wird, mit Fasern aus der Zwischenschicht verbinden.Upper layer, lower layer or both layers can consist of foams, depending on Base material and processing absorb moisture or let it diffuse through. Such Materials are usually soft and wear therefore pleasant. They are also easy to use, like later is explained in more detail with fibers from the intermediate layer connect.

Alternativ dazu ist auch Fasermaterial für die untere und/oder obere Schicht gut geeignet. Es hat ähnliche Vorzüge wie Schaumstoff, kann auch saugfähig oder diffusionsoffen sein und trägt sich ebenfalls angenehm. Alternatively, there is also fiber material for the lower one and / or top layer well suited. It has Similar benefits to foam, can also be absorbent or be open to diffusion and also wears enjoyable.

Die Schichten eines erfindungsgemäßen Sohlenaufbaus sind idealerweise dick genug, damit die obere Schicht die Feuchtigkeit gut von den Fußsohlen abschottet und die untere Schicht ausreichende Mengen an Feuchtigkeit speichern kann. Dabei sollten der Gesamtsohlenaufbau jedoch nicht zu schwer und auch nicht so dick sein, damit die Sohle insgesamt nicht schwammig wirkt. Um diese Eigenschaften zu erfüllen, hat die untere und obere Schicht jeweils ein Flächengewicht von 300 bis 400 g/m2.The layers of a sole structure according to the invention are ideally thick enough so that the upper layer seals off the moisture well from the soles of the feet and the lower layer can store sufficient amounts of moisture. However, the overall sole structure should not be too heavy and not so thick, so that the sole does not appear spongy. To meet these properties, the lower and upper layers each have a basis weight of 300 to 400 g / m 2 .

Die Zwischenschicht hat vorzugsweise ein Flächengewicht von 200 - 250 g/m2. Sie ist dann dick genug, um erhebliche Mengen Wirkstoff aufzunehmen, zumindest dann, wenn die Schicht zum Großteil aus saugfähigen Fasern besteht, und dabei dennoch recht leicht bleibt.The intermediate layer preferably has a basis weight of 200-250 g / m 2 . It is then thick enough to absorb significant amounts of the active ingredient, at least when the layer consists largely of absorbent fibers and still remains quite light.

Da die Zwischenschicht aus Fasermaterial besteht, läßt sie sich mit den beiden anderen Schichten durch Vernadeln verbinden, insbesondere dann, wenn die obere oder untere Schicht ebenfalls aus Fasermaterial gebildet sind. Es ist aber auch möglich, eine Schicht aus anderem Material, beispielsweise aus Schaumstoff, mit einer Schicht aus Fasermaterial zu vernadeln. Dieses Verfahren gewährleistet eine feste Verbindung der Schichten untereinander und ermöglicht zudem die Einführung saugfähiger Fasern aus der unteren oder Zwischenschicht in die obere Schicht, so daß dort die Feuchtigkeit abgeführt wird. Die eingenadelten Fasern wirken dabei wie Kanäle, die die Feuchtigkeit an die untere oder an die Zwischenschicht weiterleiten.Since the intermediate layer is made of fiber material, it can be combined with the other two layers connect by needling, especially if the upper or lower layer also made of fiber material are formed. But it is also possible a layer of other material, for example made of foam, with a layer of fiber material needling. This procedure ensures a firm connection between the layers and also enables the introduction of absorbent fibers from the lower or intermediate layer into the upper layer so that the moisture is removed there becomes. The needled fibers act here like channels that bring the moisture to the bottom or forward to the intermediate layer.

Ein Sohlenaufbau, insbesondere wenn er aus Fasermaterial oder Schaumstoff besteht, kann sich durch Bewegung der Füße statisch aufladen, was unangenehm ist und möglicherweise einen Juckreiz zur Folge hat. Dem kann Abhilfe geschaffen werden durch einen Sohlenaufbau, der elektrisch leitfähig ist. Diese Eigenschaft ist erreichbar durch Einbringung leitfähiger Fasern, insbesondere aus Kohlenstoff oder Stahl, die die Ladungen abführen können. Werden Schichten miteinander vernadelt, so reicht es möglicherweise bereits aus, leitfähige Fasern nur in einer der drei Schichten vorzusehen, weil dann leitfähige Fasern auch in die anderen Schichten eingeführt werden. Zudem lassen sich statische Ladungen des gesamten menschlichen Körpers durch Schuhe mit entsprechenden Sohlen kontinuierlich ableiten. Stromschläge, die durch plötzliche Entladungen entstehen könnten, werden damit vermieden. Insbesondere aber sind entsprechende Schuhe bei Bearbeitung elektronischer Geräte empfehlenswert, weil eine Beschädigung durch möglicherweise auftretende Entladungsströme unterbleibt. Auch für entsprechende Spezialschuhe ist also ein derart ausgestalteter Sohlenaufbau geeignet.A sole construction, especially if it is made of fiber material or foam, can become worn out Static charge of foot movement, which is uncomfortable and may result in itching Has. This can be remedied by one Sole construction that is electrically conductive. This Property is achievable by introducing more conductive Fibers, in particular made of carbon or Steel that can discharge the charges. Become Layers needled together, so it may be enough already out, conductive fibers only in to provide one of the three layers because then conductive fibers also in the other layers be introduced. Static charges can also be removed of the entire human body Derive shoes with appropriate soles continuously. Electric shock caused by sudden discharges could be avoided. In particular, however, appropriate shoes are being processed electronic devices recommended, because damage from possibly occurring Discharge currents are avoided. Also for corresponding ones Special shoes is therefore one designed in this way Suitable for sole construction.

Bei einer oberen Schicht aus anderem Material kann zusätzlich ein Obermaterial, insbesondere Leder, Gewebe oder Cambrell aufkaschiert werden. Dadurch ergibt sich ein zusätzlicher Schutz der oberen Schicht und damit des gesamten Sohlenaufbaus. With an upper layer made of other material additionally an upper material, especially leather, Fabric or cambrell can be laminated on. Thereby there is an additional protection of the upper one Layer and thus the entire sole structure.

Ein weiterer Gegenstand der Erfindung ist die dauerhafte Einbringung von Wirkstoffen, insbesondere Duftstoffen, in eine Zwischenschicht. Zu diesem Zweck sollte die Freisetzung der Wirkstoffe verlangsamt werden. Eine vorteilhafte Weiterbildung sieht daher vor, die Zwischenschicht oben und/oder unten, also an der Grenze zur oberen und/oder unteren Schicht, mit einer perforierten Folie zu versehen, so daß ein Austritt nur an den Perforationen möglich ist. Die Intensität des Duftstoffes ist dadurch weniger stark, hält dafür aber länger an.Another object of the invention is permanent Introduction of active ingredients, in particular Fragrances, in an intermediate layer. To this Purpose should slow the release of the active ingredients become. An advantageous training therefore provides for the intermediate layer above and / or below, i.e. on the border to the upper and / or lower Layer to be provided with a perforated film, so that an exit only at the perforations is possible. The intensity of the fragrance is thereby less strong, but lasts longer.

Ist die Zwischenschicht mit perforierten Folien versehen, so kann der Wirkstoff dennoch seitlich entweichen. Um dies zu verhindern, kann die Zwischenschicht seitlich vorzugsweise umlaufend verschlossen werden. Unter Umständen ist jedoch erwünscht, daß Wirkstoffe abschnittsweise austreten können. Damit wird erkennbar, daß der Sohlenaufbau mit einem Duft versehen ist, und auch die Duftnote läßt sich beispielsweise beim Kauf testen.Is the intermediate layer with perforated foils provided, the active ingredient can still laterally escape. To prevent this, the intermediate layer can laterally closed all around become. However, it may be desirable that active substances emerge in sections can. This shows that the sole structure is provided with a fragrance, and also the fragrance note can be tested, for example, when buying.

Weitere Einzelheiten, Merkmale und Vorteile der Erfindung lassen sich dem nachfolgenden Beschreibungsteil entnehmen, in dem anhand einer Figur, die in prinzipienhafter Darstellung gehalten ist, ein Ausführungsbeispiel der Erfindung näher erläutert wird. Sie zeigt einen senkrechten Schnitt durch einen erfindungsgemäßen Sohlenaufbau.Further details, features and advantages of the invention can be found in the following description remove, in the example of a figure, the is kept in a principled representation Embodiment of the invention explained in more detail becomes. It shows a vertical section through a sole structure according to the invention.

Der Sohlenaufbau besteht aus einer oberen Schicht (1) und einer davon beabstandeten unteren Schicht (2). Zwischen diesen beiden Schichten ist eine Zwischenschicht (3) eingebracht, die die Wirkstoffe enthält und von der oberen Schicht (1) oder der unteren Schicht (2) zudem jeweils durch eine perforierte Folie (4) getrennt sein kann, so daß sicherstellt ist, daß der Wirkstoff nur langsam austritt. Insgesamt ergibt sich ein Sohlenaufbau, in dem ein Wirkstoff in einer Zwischenschicht (3) definiert eingebracht ist. Die obere Schicht (1) und die untere Schicht (2) schotten den Wirkstoff gegenüber der Fußsohle oder dem restlichen Aufbau des Schuhs ab. Mit dieser Anordnung läßt sich insbesondere ein Schuh mit einem lang anhaltenden Duft versehen.The sole structure consists of an upper layer (1) and a spaced lower layer (2). There is an intermediate layer between these two layers (3) introduced the active ingredients contains and from the upper layer (1) or the lower Layer (2) also through a perforated Foil (4) can be separated so that ensures is that the active ingredient escapes only slowly. Overall, there is a sole structure in which a Active ingredient defined in an intermediate layer (3) is introduced. The top layer (1) and the bottom Layer (2) seals off the active ingredient the sole of the foot or the rest of the structure of the shoe from. With this arrangement, one can in particular Provide the shoe with a long-lasting fragrance.
