Description

Die Erfindung bezieht sich auf eine Teppichunlcrlage der im Oberbegriff von Anspruch 1 genannten Art.The invention relates to a carpet underlay of the type mentioned in the preamble of claim 1.

Teppichunterlagen, die aus dem DE-GM 18 87 324 und CH-PS 4 45 753 bekannt sind, können aus geschlossenporigem Schaumstoff mit einer Armicrungs-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 Teppichsauf einem glatten Boden, z. B. Parkettboden.Carpet underlays, which are known from DE-GM 18 87 324 and CH-PS 4 45 753, can be made from closed-cell foam with a reinforcement intermediate layer. They serve as suspension when walking on the carpet placed on it, reduce the wear and tear of the carpet and also work heat and sound insulating. With a suitable design of the outer layers, they prevent the Carpet on a smooth floor, e.g. B. parquet floor.

Derartige Tcppichunterlagen 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 Velourteppichboden, 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 sindSuch 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. 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 of these materials can fulfill 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 are

to Teppichunterlagen in Gestalt eines Netzes aus sainststoffummantelten, 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 Forderungen, nämlich Federung, Schalldämmung, Wärmeisolatrm und sind schon gar nicht als Teppichzwischenlagen brauchbar. Sie können also das Wandern eines Teppichs auf einem Teppichboden nicht verhindern.to carpet underlays 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 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 sehrFrom DE-GM 19 83 663 a lot is very

unterschiedlicher Vorschläge zur Ausbildung einer Teppichunterlage bekannt. Allen gemeinsam ist, daß die Teppichunterlage eine zähelastische bis nahezu harte Deckschicht hat. Diese kann zwar auch als Vlies ausgebildet sein, soll 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.different proposals for the formation of a carpet underlay known. What they all have in common is that Carpet underlay has a viscoplastic to almost hard top layer. This can also be used as a fleece be formed, but should be impregnated with gutta-percha or special oil varnishes. Such a layer excludes use as a carpet interlayer. The strongly consolidated fleece is not able to to claw in the carpet or carpet, so prevent the carpet from moving. The other outer layer should in turn consist of one of one Variety of material to be selected, namely rubber, rubber, foam rubber, plastic foams or similar materials. Materials of this kind. Also closed-cell plastic foams.

sind aber nicht geeignet, die erforderliche Vcrkrallung herbeizuführen.but are not suitable for the necessary clawing bring about.

Ferner haben derartige Teppichunterlagcn mit einer zähelastischen bis nahezu harten Deckschicht den Nachteil, daß sie entweder überhaupt nicht gerollt werden können oder daß Rollen c:'nen 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, carpet underlays of this type with a viscoplastic to almost hard cover layer have the Disadvantage that they either cannot be rolled at all or that rolls are very large Must have a diameter so that the base does not break. But this means difficulties during transport, storage and handling in the event of use.

Durch die vorliegende Erfindung soll eine Tcppichunterlage geschaffen werden, die nicht nur als solche sondern auch als Zwischenlage zwischen einem Teppich und einem Teppichboden verwendbar ist und dann zuverlässig das Wandern des Teppichs auf demThe present invention is intended to provide a carpet underlay that is not only as such but can also be used as an intermediate layer between a carpet and a carpeted floor and then reliably wandering the carpet on the

Wird die Teppichunterlagc zwischen Teppich und einen Teppichboden eingefügt, so wird, jeh5 floor is used and should 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-AuBenschichi entweder nach unten oder nach oben gekehrt.according to the material of both, the foam outer layers either turned down or up.

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 Raumgewicht weiter gesenkt werden.As an intermediate layer, woven or knitted fabrics, a plastic film, paper can be used in a known manner or cardboard can be used. In an advantageous development according to claim 2, however, as Interlayer a strongly consolidated thin fiber fleece can be used. This can reduce the manufacturing costs and the volume weight can be further reduced.

Vorzugsweise werden für das Faservlies der zweiten ι ο Außenschicht synthetische Fasern verwendet, insbesondere Fasern aus Polypropylen, Polyester, Polyamid oder Acrylfasern.Preferably, the second ι ο Outer layer used synthetic fibers, in particular fibers made of polypropylene, polyester, or polyamide Acrylic fibers.

Die beiden AuBenschichten lassen sich mit der Armierungszwischenlage auf verschiedene Weise ver- is binden, 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 AuBenschichten und die Zwischenlage miteinander.The two outer layers can be covered with the reinforcement intermediate layer in different ways bind, e.g. B. by mechanical needling, the Needles from the side of the foam layer into or through the loose fiber fleece pierced through and then withdrawn. They connect the two with their barbs Outer layers and the intermediate layer with one another.

Statt dessen kann die Verbindung durch Verkleben oder oberflächliches Schmelzen und Andrücken der Schaumstoffschicht hergestellt werden.Instead, the connection can be made by gluing or superficial melting and pressing of the Foam layer can be produced.

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