Description

Die Erfindung bezieht sich auf eine Tcppichuntcrlagc der im Oberbegriff von Anspruch I genannten Art.The invention relates to a carpet cover of the type mentioned in the preamble of claim I.

Teppichunterlagen, die aus dem Df-GM 18 87 324 und CUPS 4 45 75J bekannt sind, können aus gcschlossenporigem Schaumstoff mit einer Armierungs-Zwischenlage hergestellt sein. Sie dienen als Federung beim Begehen des daraufgelegten Teppichs, vermindern die Abnutzung des Teppichs und wirken außerdem wärme- und schallisolierend. Bei geeigneter Ausbildung der Außenschichten verhindern sie ein Rutschen des Teppichs auf einem glatten Boden, /. B. Parkettboden.Carpet underlays from Df-GM 18 87 324 and CUPS 4 45 75J are known, can be made of closed-cell foam with an intermediate reinforcement layer be made. They serve as suspension when walking on the carpet that is placed on it, reducing it the wear and tear of the carpet and also have a heat and sound insulating effect. With suitable training the outer layers prevent the carpet from slipping on a smooth floor, /. B. parquet floor.

Derartige Teppichunterlagen können zwar auch als Zwischenlage zwischen einem Teppich, insbesondere einer Brücke, und einem Fußbodenbelag verwendet werden, können aber nicht das Wandern des Teppichs auf diesem Bodenbelag, insbesondere einem Velourieppichboden, verhindern. Andererseits ist es bekannt, ein Faservlies oder eine Schaumstoffmatte als Teppichunterlage oder als Teppichzwischenlage zu verwenden. Matten aus diesen Materialien können zwar beide Aufgaben erfüllen, haben jedoch den Nachteil, daß sie in Längs- und Querrichtung instabil sind. Nach einiger Zeit schauen sie unter dem Rand des Teppichs hervor. Sie verschleißen schnell und zerreißen. Andererseits sind Teppichunterlagen in Gestalt eines Netzes aus kunststoffummantelten, sich kreuzenden Fäden bekannt. Diese Unterlagen können nur die Aufgabe erfüllen, das Rutschen eines Teppichs auf einem glatten Fußboden zu verhindern, erfüllen aber nicht die sonstigen Fürderung.:n, nämlich Federung, Schalldämmung, Wärmeisolalion und sind schon gar nicht als Teppichzwischenlagen brauchbar. Sie können also das Wandern eines Teppichs auf einem Teppichboden nicht verhindern.Such carpet underlays can also be used as an intermediate layer between a carpet, in particular a bridge, and flooring can be used, but not walking the carpet on this floor covering, especially a velor carpet floor. On the other hand, it is known to be a To use fiber fleece or a foam mat as a carpet underlay or as a carpet interlayer. Mats made from these materials can perform both tasks, but have the disadvantage that they are in Longitudinal and transverse directions are unstable. After a while they will peek out from under the edge of the carpet. she wear out quickly and tear. On the other hand, carpet underlays are in the form of a network of plastic-coated, crossing threads known. These documents can only fulfill the task that To prevent a carpet from slipping on a smooth floor, but does not meet the other requirements.: N, namely suspension, sound insulation, heat insulation and are certainly not used as carpet interlayers useful. So you cannot prevent a carpet from wandering on a carpeted floor.

Aus dem DE-GM 19 83 663 ist eine Fülle sehr unterschiedlicher Vorschläge zur Ausbildung einer Teppichunterlage bekann:. Alien gemeinsam ist, daß die Teppichunterlage eine zähelastische bis nahezu harte Deckschicht hat. Diese kann zwar auch als Vlies ausgebildet sein, sol! jedoch mit Guttapercha oder Spezialöllacken getränkt sein. Eine solche Schicht schließt eine Verwendung als Teppichzwischenlage aus. Das stark verfestigte Vlies ist nämlich nicht in der Lage, sich im Teppichboden oder Teppich zu verkrallen. um so das Wandern des Teppichs zu verhindern. Die andere Außenschicht soll wiederum aus einem aus einer Vielzahl auszuwählenden Material hergestellt werden, nämlich aus Kautschuk, Gummi, Schaumgummi, Kunststoffschäumen oder ähnlichen Materialien. Materialien dieser Art, auch geschlossenporige Kunststoffschäume,From DE-GM 19 83 663 a lot is very different proposals for the formation of a carpet underlay known :. What alien has in common is that Carpet underlay has a viscoplastic to almost hard top layer. This can also be used as a fleece be trained, sol! however, be soaked with gutta-percha or special oil varnishes. Such a layer excludes use as a carpet interlayer. The strongly consolidated fleece is not able to clawing in carpets or carpets. so as to prevent the carpet from wandering. The other The outer layer should, in turn, be made of one of a large number of materials to be selected, namely made of rubber, rubber, foam rubber, plastic foams or similar materials. materials of this type, including closed-cell plastic foams,

J5 sind aber nicht geeignet, die erforderliche Verkrallung herbeizuführen.J5, however, are not suitable for the necessary clawing bring about.

Ferner haben derartige Tcppichunterlagen mit einer zähelastischen bis nahezu harten Deckschicht den Nachteil, daß sie entweder überh 'unt nicht gerollt werden können oder daß Rollen einen sehr großen Durchmesser haben müssen, damit nämlich die Unterlage nicht bricht. Dies bedeutet aber Schwierigkeiten beim Transport, der Lagerung und der Handhabung im Anwendungsfalle.Furthermore, such carpet underlays with a viscoplastic to almost hard cover layer have the Disadvantage that they either cannot be rolled at all or that rolling is a very large one Must have a diameter, namely the base does not break. But this means difficulties in transport, storage and handling in the Use cases.

Durch die vorliegende Erfindung soll eine Teppichunterlage geschaffen werden, die nicht nur als solche sondern auch als Zwischenlage /wischen einem Teppich und einem Teppichboden verwendbar ist und dann zuverlässig das Wandern des Teppichs auf dem Teppichboden verhindert.The present invention aims to provide a carpet underlay created not only as such but also as an intermediate layer / wipe a carpet and a carpet is usable and then reliably wandering the carpet on the Carpet prevented.

Die Aufgabe wird crfindungsgcmiiß durch die im kennzeichnenden Teil des Patentanspruchs 1 angegebenen Merkmale gelöst.The task is determined by the im characterizing part of claim 1 specified features solved.

Durch die Verwendung einerseits eines offenporigenBy using, on the one hand, an open-pore

v, Schaumstoffs, andererseits eines lockeren Faservlieses als AuBenschichten erzielt man an beiden Seiten die erwünschte Verkrallungswirkung und verhindert damit das Wandern eines Teppichs auf einem Teppichboden. Durch Verwendung dieser relativ billigen Materialien v, foam, on the other hand a loose fiber fleece as outer layers, the desired clawing effect is achieved on both sides and thus prevents a carpet from moving on a carpeted floor. By using these relatively cheap materials

M) ergibt sich insgesamt eine preisgünstige Teppichunicrlage. Die Unterlage läßt sich zusammenfalten, wodurch Lagerung, Transport und Handhabung erleichtert werden.M) the overall result is an inexpensive carpet unicrlage. The pad can be folded up, which makes storage, transport and handling easier will.

Wird die Teppichunterlage zwischen Teppich und Fußboden verwendet und soll sie rutschhemmend wirken, so wird die Schaumstoff-Außenschicht nach unten gekehrt. Wird die Teppichunterlagc zwischen Teppich und einen Teppichboden eingefügt, so wird, jeIf the carpet underlay is used between the carpet and the floor and should it be slip-resistant act, the foam outer layer is turned downwards. If the carpet underlay is between Carpet and carpeting inserted, so will, depending

nach dem Material von beiden, die Schaumstoff-AulJenschicht entweder nach unten oder nach oben gekehrt.depending on the material of both, the foam outer layer either turned up or down.

Als Zwischenlage können in bekannter Weise Gewebe oder Gewirke, eine Kunststoff-Folie, Papier oder Pappe verwendet werden. In vorteilhafter Weiterbildung gemäß Anspruch 2 kann jedoch als Zwischenlage ein stark verfestigtes dünnes Faservlies verwendet werden. Hierdurch können die Herstellungskosten und das Paumgewicht weiter gesenkt werden. As an intermediate layer, woven or knitted fabrics, a plastic film, paper or cardboard can be used in a known manner. In an advantageous further development according to claim 2, however, a strongly consolidated thin fiber fleece can be used as the intermediate layer. As a result, the manufacturing costs and the weight of the palette can be further reduced.

Vorzugsweise werden für das Faservlies der zweiten Außenschicht synthetische Fasern verwendet, insbeson dere Fasern aus Polypropylen, Polyester, Polyamid oder Acrylfasern. Synthetic fibers are preferably used for the nonwoven fabric of the second outer layer, in particular fibers made of polypropylene, polyester, polyamide or acrylic fibers.

Die beiden Außenschichten lassen sich mit der Armierungszwischenlage auf verschiedene Weise verbinden, z. B. durch mechanische Vernadelung, wobei die Nadeln von der Seite der Schaumstoffschicht her bis in das lockere Faservlies hinein oder durch dieses hindurchgestochen und dann zurückgezogen werden. Mit ihren Widerhaken vernetzen sie die beiden Außenschleifen und die Zwischenlage miteinander. The two outer layers can be connected to the reinforcement intermediate layer in various ways, e.g. B. by mechanical needling, wherein the needles are pierced from the side of the foam layer into or through the loose fiber fleece and then withdrawn. With their barbs they network the two outer loops and the intermediate layer with one another.

Statt dessen kann die Verbindung durch '-erkleben oder oberflächliches Schmelzen und Andrücken der Schaumstoffschichi hergestellt werden. Instead, the connection can be made by gluing or superficial melting and pressing of the foam layers.

Schließlich können zusätzlich alle drei Schichten durch kreuz und quer verlaufende Steppnähte miteinander verbunden werden. Finally, all three layers can also be connected to one another with criss-cross stitching.

Ein Ausführungsbeispiel der Erfindung ist in der Zeichnung dargestellt. Die Zeichnung zeigt einen Querschnitt durch ein Stück einer Teppichunterlage mit jo einer ersten Außenschicht 1 aus Schaumstoff, einer zweiten Außenschicht 2 aus einem lockeren Faservlies und einer Armierungsschicht 3 aus einem Gev\ rbe.
