Abstract

Description

Die Erfindung betrifft eine Schuheinlage aus einem geschlossenzellig geschäumten, vernetzten Polyolefinkörper und einer auf der Nutzfläche angeordneten Faserschicht.The invention relates to a shoe insert made of a closed-cell foamed, crosslinked polyolefin body and a fiber layer arranged on the usable surface.

Schuheinlagen der angegebenen Art sind seit langem bekannt (DE-U-8 108 693). Sie zeichnen sich neben einer guten Wärmedämmung durch eine gute Anpassungsfähigkeit an den menschlichen Fuss aus, dämpfen Schwingungen und Stösse in ausgezeichneter Weise und verhalten sich über lange Zeiträume inert gegenüber aggressiven Flüssigkeiten. Sie lassen sich leicht umformen und können insofern als geradezu ideal angesehen werden in bezug auf die Ausstattung sowohl orthopädischen als auch modisch geschnittenen Schuhwerkes. Die Feuchtigkeitsaufnahmefähigkeit und die Wasserdampfdurchlässigkeit sind jedoch ausserordentlich gering. Insbesondere bei Verwendung dünner Strümpfe aus synthetischen Faserstoffen kann es dadurch bei geschlossenem Schuhwerk nach längerem Gebrauch im Bereich der Fusssohle zu einem Feuchtigkeits- und Wärmestau kommen, der als weniger angenehm empfunden wird. Es entstand deshalb der Wunsch, Einlegesohlen der angegebenen Art derart weiter zu entwickeln, dass auch bei stärkerer Schweissabsonderung und nach längerer Zeit ein derartiger Feuchtigkeits-und Wärmestau im Bereich der Fusssohle mit grosser Sicherheit vermieden wird bzw. die Wärmedämmung reguliert wird. Die vorerwähnten Vorteile dürfen bei der Lösung dieser Aufgabe keinerlei Beeinträchtigung erfahren.Shoe inserts of the specified type have long been known (DE-U-8 108 693). In addition to good thermal insulation, they are characterized by good adaptability to the human foot, dampen vibrations and shocks in an excellent manner and are inert to aggressive liquids over long periods of time. They can be easily reshaped and can therefore be regarded as almost ideal in terms of the equipment of both orthopedic and fashionably cut footwear. However, the moisture absorption and water vapor permeability are extremely low. Especially when using thin stockings made of synthetic fibers, this can lead to moisture and heat build-up in closed footwear after prolonged use, which is perceived as less pleasant. There was therefore a desire to further develop insoles of the type specified in such a way that even with increased sweating and after a long period of time, such a build-up of moisture and heat in the area of the foot sole is avoided with great certainty or the thermal insulation is regulated. The above-mentioned advantages must not be impaired in solving this task.

Erfindungsgemäss wird eine Schuheinlage aus einem geschlossenzellig geschäumten, vernetzten Polyolefinkörper und einer auf der Nutzfläche angeordneten Faserschicht vorgeschlagen, bei dem die Faserschicht aus musterartig über die Nutzfläche verteilten Fasern oder Fäden besteht, die den Polyolefinkörper ganz oder teilweise durchdringen. Die Fasern oder Fäden bzw. der enge Spalt zwischen ihnen und dem umgebenden Schaumstoffkörper begünstigen bei der vorgeschlagenen Schuheinlage den Transport von Feuchtigkeit und Wasserdampf aus dem Bereich der Nutzfläche zur Unterseite. Aus diesem Bereich, der im allgemeinen mit feuchtigkeitsdurchlässigen Stoffen abgedeckt ist, ist jederzeit eine gute Ableitung gewährleistet. Die vorgeschlagene Schuheinlage gewährleistet aus diesem Grunde nicht nur eine grosse Wärmedämmung und eine gute Anpassbarkeit an das Schuhwerk und den menschlichen Fuss, sondern zusätzlich einen besonders hohen Tragekomfort insofern, als ein Wärme- und Feuchtigkeitsstau im Bereich der Nutzfläche sicher vermieden wird. Die Luftdurchlässigkeit und damit die Atmungsaktivität werden deutlich verbessert.According to the invention, a shoe insert is proposed consisting of a closed-cell, foamed, crosslinked polyolefin body and a fiber layer arranged on the usable surface, in which the fiber layer consists of fibers or threads distributed in a pattern over the usable surface, which completely or partially penetrate the polyolefin body. The fibers or threads or the narrow gap between them and the surrounding foam body favor the transport of moisture and water vapor from the area of the usable surface to the underside in the proposed shoe insert. Good drainage is guaranteed at all times from this area, which is generally covered with moisture-permeable substances. For this reason, the proposed shoe insert not only ensures great thermal insulation and good adaptability to the footwear and the human foot, but also a particularly high level of comfort insofar as a build-up of heat and moisture in the area of the usable area is reliably avoided. The air permeability and thus the breathability are significantly improved.

Die Faserschicht kann auf die Oberfläche des Polyolefinkörpers aufgeschweisst oder aufgeklebt werden. In beiden Fällen bildet sich zwischen der eigentlichen Faserschicht und der Oberseite des Polyolefinkörpers eine folienartige Schicht aus, die wesentlich zur menschlichen Stabilisierung beiträgt.The fiber layer can be welded or glued to the surface of the polyolefin body. In both cases, a film-like layer is formed between the actual fiber layer and the top of the polyolefin body, which contributes significantly to human stabilization.

In vielen Fällen ist eine derartige Stabilisierung nicht erwünscht, und die Faserschicht kann in diesen Fällen auch lose auf die Oberseite des Polyolefinkörpers aufgelegt und mit diesem lediglich durch die ihn ganz oder teilweise durchdringenden Fasern oder Fäden verbunden werden. Die Nutzfläche fühlt sich in diesem Falle besonders weich, geschmeidig und elastisch an.In many cases, such stabilization is not desired, and in these cases the fiber layer can also be placed loosely on the top of the polyolefin body and connected to it only by the fibers or threads penetrating all or part of it. In this case, the usable surface feels particularly soft, supple and elastic.

Die Fasern oder Fäden enthalten eine grössere Anzahl einzelner Fasern, die durch eine gegenseitige Verflechtung, durch Verspinnen und/oder durch ein Bindemittel vereinigt sind. Die einzelnen Fasern eines Bündels können gleiche oder unterschiedliche Länge haben.The fibers or threads contain a large number of individual fibers, which are combined by interweaving, spinning and / or by a binder. The individual fibers of a bundle can have the same or different lengths.

Die textile Faserschicht kann aus lose aufgelegten Fasern oder Fäden bestehen, die untereinander nur durch in den Polyolefinkörper hinein- oder hindurchgezogene Fasern oder Fäden verbunden sind. Die Abriebfestigkeit kann in Abhängigkeit von der Art der verwendeten Fasern oder Fäden zu wünschen übrig lassen.The textile fiber layer can consist of loosely placed fibers or threads which are connected to one another only by fibers or threads drawn into or through the polyolefin body. The abrasion resistance may leave something to be desired, depending on the type of fibers or threads used.

Bevorzugt wird deshalb häufig eine Faserschicht, die in sich eine gute Eigenstabilität aufweist. Als besonders geeignet hat sich die Verwendung von Geweben, Gewirken und/oder Vliesstoffen erwiesen. Das Flächengewicht kann bei einer Dicke von 1 bis 3 mm zweckmässig 50 bis 250 g/m2 betragen.For this reason, preference is often given to a fiber layer that has good inherent stability. The use of fabrics, knitted fabrics and / or nonwovens has proven to be particularly suitable. With a thickness of 1 to 3 mm, the weight per unit area can expediently be 50 to 250 g / m 2 .

Die Feuchtigkeitsableitung durch den Polyolefinkörper hindurch wird begünstigt durch Verwendung einer Faserschicht mit einem Gehalt an Feuchtigkeit aufsaugenden Fasern oder Fäden. Mit zunehmendem Feuchtigkeitsgehalt steigt in diesem Falle auch die Wärmeleitfähigkeit, was gleichbedeutend ist mit einer von der Beaufschlagung abhängigen Regulierung des Wärmetransports. Fasern oder Fäden aus Baumwolle oder Zellwolle haben sich ausgezeichnet bewährt. Das Flächengebilde kann jedoch auch ausschliesslich oder neben den vorgenannten Fasern oder Fäden solche mit einer besonders hohen Sprungelastizität aus hydrophoben Werkstoffen enthalten. Die Sprüngigkeit und der weiche Griff der Oberfläche bleiben hierdurch langfristig erhalten, insbesondere, wenn die Fasern oder Fäden gekräuselt sind.The moisture dissipation through the polyolefin body is promoted by using a fiber layer containing moisture-absorbing fibers or threads. In this case, as the moisture content increases, the thermal conductivity also increases, which is equivalent to a regulation of the heat transport that is dependent on the exposure. Fibers or threads made of cotton or rayon have proven to be excellent. However, the flat structure can also contain exclusively or in addition to the aforementioned fibers or threads those with a particularly high elasticity from hydrophobic materials. This ensures that the surface remains flat and soft to the touch, especially if the fibers or threads are crimped.

Die musterartig über die Fläche verteilten Fasern oder Fäden können einen regelmässig wiederkehrenden, geringen Abstand voneinander haben. Der kleinste Abstand zweier benachbarter Fasern oder Fäden soll wenigstens so gross sein wie die dreifache Faser- oder Fadendicke, jedoch nicht grösser als die Dicke des Polyolefinkörpers. Die einzelnen Fasern oder Fäden können soweit durch den Polyolefinkörper hindurchragen, dass die Unterseite frei herausstehende Faser- oder Fadenenden aufweist. Der Weitertransport der Feuchtigkeit ist hierdurch in besonders guter Weise gewährleistet.The fibers or threads distributed in a pattern over the surface can have a regularly recurring, small distance from one another. The smallest distance between two adjacent fibers or threads should be at least as large as three times the fiber or thread thickness, but not greater than the thickness of the polyolefin body. The individual fibers or threads can protrude through the polyolefin body to such an extent that the underside has protruding fiber or thread ends. The further transport of the moisture is guaranteed in a particularly good way.

Die Fasern oder Fäden können mit der Unterseite des Polyolefinkörpers verklebt sein und insofern der auf der Nutzfläche angeordneten Faserschicht einen zusätzlichen Halt verleihen. Ein gleichwertiger Halt, verbunden mit einer zusätzlich verbesserten Feuchtigkeitsableitungsfähigkeit, lässt sich daneben jedoch dann erzielen, wenn die aus der Unterseite des Polyolefinkörpers hervorstehenden Faser- oder Fadenenden mit einer in diesem Bereich speziell angebrachten Saugschicht verbunden sind. Diese kann beispielsweise aus einem künstlichen oder natürlichen Leder, einem offenporigen Schaumstoff, einer an sich verfestigten Faserschicht und/oder aus Zellstoff bestehen. Die Saugschicht liegt unmittelbar auf der Rückseite der eigentlichen Schuhsohle auf.The fibers or threads can be glued to the underside of the polyolefin body and, in this respect, give the fiber layer arranged on the usable surface an additional hold. A equivalent hold, combined with an additionally improved ability to wick away moisture, can, however, also be achieved if the fiber or thread ends protruding from the underside of the polyolefin body are connected to a suction layer specially provided in this area. This can consist, for example, of an artificial or natural leather, an open-cell foam, an inherently solidified fiber layer and / or cellulose. The absorbent layer lies directly on the back of the actual shoe sole.

Die Fasern oder Fäden können senkrecht, jedoch auch schräg und sich gegebenenfalls gegenseitig durchschneidend den Polyolefinkörper durchdringen. Die Festigkeit der Verankerung der Faserschicht kann hierdurch eine zusätzliche Steigerung erfahren. Das Raumgewicht des geschlossenzellig geschäumten, vernetzten Polyolefinkörpers liegt bevorzugt im Bereich zwischen 50 und 120 kg/m3. Seine Nutzfläche ist vorzugsweise an die Gestalt des menschlichen Fusses orthopädisch angepasst. Die Ausbildung der neuen Schuheinlage kann dabei entsprechend den idealen Verhältnissen je Grösse folgen, die wesentlich zum individuellen Tragekomfort beitragende Feinanpassung ergibt sich selbsttätig während der Benutzung.The fibers or threads can penetrate the polyolefin body vertically, but also obliquely and, if necessary, intersecting one another. The strength of the anchoring of the fiber layer can experience an additional increase. The density of the closed-cell foamed, crosslinked polyolefin body is preferably in the range between 50 and 120 kg / m 3 . Its usable area is preferably orthopedically adapted to the shape of the human foot. The design of the new shoe insert can follow the ideal conditions for each size, the fine adjustment, which contributes significantly to the individual wearing comfort, results automatically during use.

Die Schuheinlage kann nachträglich auf eine saugfähige Brandsohle aufgebracht sein, beispielsweise durch Kleben oder Schweissen, sie kann jedoch auch im Schuhwerk lose eingefügt werden. Im einfachsten Falle besteht sie aus einem ebenen Flächengebilde mit planparallelen Oberflächen, das entsprechend der Gestalt der Decksohle des Schuhwerks zugeschnitten ist. Daneben ist jedoch auch eine orthopädische Ausbildung möglich, beispielsweise durch eine Erwärmung und Verformung mit einem entsprechend der Gestalt des menschlichen Fusses gestalteten Pressenwerkzeug. Wird eine Faserschicht mit einem Gehalt an thermisch schrumpfbaren Fasern verwendet, dann bietet es sich an, die zum Umformen erforderliche Erwärmung so durchzuführen, dass die Schrumpfkräfte der Fasern aktiviert werden. Die Verankerung einer zunächst nur lose auf die Nutzfläche aufgelegten Faserschicht erfährt hierdurch während der Umformung eine deutliche Steigerung.The shoe insert can subsequently be applied to an absorbent insole, for example by gluing or welding, but it can also be inserted loosely in the footwear. In the simplest case, it consists of a flat fabric with plane-parallel surfaces, which is tailored to the shape of the insole of the footwear. In addition, however, orthopedic training is also possible, for example by heating and deforming with a press tool designed according to the shape of the human foot. If a fiber layer with a content of thermally shrinkable fibers is used, then it makes sense to carry out the heating necessary for the shaping in such a way that the shrinking forces of the fibers are activated. The anchoring of a fiber layer that was initially only loosely placed on the usable surface experiences a significant increase during the forming.

Die in der Anlage beigefügte Zeichnung zeigt eine beispielhafte Ausführung der erfindungsgemäss vorgeschlagenen Schuheinlage in quergeschnittener Darstellung.The attached drawing shows an exemplary embodiment of the shoe insert proposed according to the invention in a cross-sectional representation.

Die dargestellte Ausführung besteht aus einem geschlossenzellig geschäumten, vernetzten Polyolefinkörper, der bei einem Raumgewicht von 90 kg/m3 eine Dicke von 7 mm und planparallele Oberflächen aufweist. Auf die Nutzfläche ist eine Faserschicht 2 lose aufgelegt. Diese besteht aus einem Vliesstoff, der bei einer Dicke von 3 mm ein Flächengewicht von 60 g/m2 aufweist. Der Vliesstoff besteht zu 60% aus Baumwollfasern, zu 40% aus grobstrukturierten Polypropylenfasern.The version shown consists of a closed-cell, foamed, cross-linked polyolefin body, which has a thickness of 7 mm and plane-parallel surfaces at a density of 90 kg / m 3 .

The nonwoven consists of 60% cotton fibers and 40% coarse structured polypropylene fibers.

Aus der Unterseite des Polyolefinkörpers 1 ragen die Enden 4 der Fasern 5 heraus und sind seitlich umgelegt. Sie haben einen flächigen Kontakt zu der Oberfläche der auf die Unterseite aufgeklebten Brandsohle 3 aus einem Lederfaserstoff. Die Brandsohle hat bei einer Dicke von 1,2 cm ein Flächengewicht von 200 g/m2. Sie zeichnete sich durch eine besonders hohe Wasseraufnahmefähigkeit aus.The ends 4 of the fibers 5 protrude from the underside of the polyolefin body 1 and are folded over laterally. They are in flat contact with the surface of the insole 3 made of a leather fiber material and glued to the underside. The insole has a basis weight of 200 g / m 2 with a thickness of 1.2 cm. It was characterized by a particularly high water absorption capacity.
