Selbstaufblasende LiegematteSelf-inflating lying mat
Beschreibungdescription
Die vorliegende Erfindung betrifft eine selbstaufblasende Legematte oder Kissen mit den Merkmalen des Oberbegriffs des Anspruchs 1.The present invention relates to a self-inflating mat or pillow with the features of the preamble of claim 1.
Bekannt sind Matten mit leichtem Gewebe und Vorbeschichtung mit Lösungsmittel aus PU und mindestens 2 Beschichtungslagen, in der Regel aus PU-Filmen, wobei die außenliegende Beschichtungslage als niedrigerschmelzendes Klebesystem ausgebildet ist (US-PS 4,624,877). Diese Matten bestehen aus zwei Lagen dieses beschichteten Gewebes zwischen die ein leichter Schaumstoff eingeklebt wird, wobei die Ränder der beschichteten Gewebe verschweißt werden. Diese luftdichte Matte wird dann durch ein Ventil aufgeblasen. Die maximale Dicke der Matte wird durch die voUflächige Verklebung durch die Dicke des Schaumes begrenzt. Bei geschlossenem Ventil ist diese Matte sehr druckstabil und hat ein gutes Isolierverhalten, trotz geringer Schaumdicke. Deswegen ist sie relativ leicht und wird sehr gerne von Wanderern und Bergsteigern eingesetzt. Sie ist sehr komfortabel. Damit die Schweißnähte dem hohen Druck auf Ihre Schweißnähte Stand hält, muß eine Lösungsmittelvorbeschichtung auf das Gewebe aufgetragen werden. Diese Vorbeschichtung schädigt zum einen das Gewebe in seiner Festigkeit und zum anderen die Umwelt, da Lösungsmittel verwendet werden. Die Vorbeschichtung
ist auch regelmäßig sensibel hinsichtlich Ihrer UV-Beständigkeit, so daß viele Matten im Gebrauch auf Dauer versagen. Weiterhin sind diese Matten oft sehr rutschig, da sie aus Gewichtsgründen oft nur einseitig beschichtet sind. Da das Gewebe außen relativ rutschig ist, ist dies dann sehr unangenehm an abschüssigen Liegeplätzen beim Camping. Dem versucht man durch Kunstfaser-Gewebe mit Baumwollstruktur beizukommen, wodurch die Rutschneigung nur bedingt abnimmt. Weiterhin sind diese Gewebe oft nicht so durchstoßsicher, so daß man an der Unterseite gerne glatte Hochfeste Nylongarne verwendet. Dies führt jedoch bisweilen zu einer Bananenform der Matte, da verschiedene Materialien unterschiedliches Ausdehnungsverhalten haben. Einseitig außen liegendeMats with light fabric and precoating with solvent made of PU and at least 2 coating layers, usually made of PU films, are known, the external coating layer being designed as a low-melting adhesive system (US Pat. No. 4,624,877). These mats consist of two layers of this coated fabric between which a light foam is glued in, the edges of the coated fabric being welded. This airtight mat is then inflated through a valve. The maximum thickness of the mat is limited by the gluing of the foam. When the valve is closed, this mat is very pressure-stable and has good insulation properties, despite the low foam thickness. That is why it is relatively light and is very popular with hikers and mountaineers. It is very comfortable. In order for the weld seams to withstand the high pressure on your weld seams, a solvent precoat must be applied to the fabric. This pre-coating damages the strength of the fabric on the one hand and the environment on the other because solvents are used. The pre-coating is also regularly sensitive to its UV resistance, so that many mats fail over time. Furthermore, these mats are often very slippery, since they are often only coated on one side for weight reasons. Since the fabric is relatively slippery on the outside, this is very uncomfortable on sloping berths when camping. One tries to deal with this with synthetic fiber fabric with a cotton structure, whereby the tendency to slip only decreases to a limited extent. Furthermore, these fabrics are often not so puncture-proof, so that smooth high-strength nylon yarns are often used on the underside. However, this sometimes leads to a banana shape of the mat, since different materials have different expansion behavior. One-sided outside
Beschichtungen nehmen dann auch leicht Schmutz und Wasser auf, wobei sie sich schlecht reinigen lassen.Coatings then easily absorb dirt and water, whereby they are difficult to clean.
Aufgabe der vorliegenden Erfindung ist es, eine selbstaufblasende Liegematte zu schaffen, die geschilderten Nachteile überwindet, indem eine neue Gewebe, Beschichtungs- und Schaumverbindungskonstruktion vorgeschlagen wird.The object of the present invention is to create a self-inflating lying mat which overcomes the disadvantages described by proposing a new fabric, coating and foam connection construction.
Erfindungsgemäß ist eine selbstaufblasende Liegematte oder Kissen aus beidseitig durch äußere Lagen eines Gewebes luftdicht eingedecktem offenzelligem Schaumstoff, wobei die äußeren Lagen randseitig verschweißt sind und wenigstens ein Ventil für die Verbindung des Schaumstoffs mit der Umgebungsatmosphäre vorhanden ist, dadurch gekennzeichnet, daß auf wenigstens einer Seite wenigstens eine Lage eines Gewebes oder Gewirkes vorhanden sind und daß das Gewebe oder aus einem heißgepressten, mit einem thermoplastischen Kunststoffbeschichteten Garn besteht. Die Beschichtung des Garnes erfolgt vor dem Weben. Das Gewebe wird dann beispielsweise kalandriert.According to the invention, a self-inflating lying mat or pillow made of open-cell foam covered airtightly on both sides by outer layers of a fabric, the outer layers being welded on the edges and at least one valve for connecting the foam to the ambient atmosphere, characterized in that at least on at least one side there is a layer of a woven or knitted fabric and that the woven fabric or consists of a hot-pressed yarn coated with a thermoplastic plastic. The yarn is coated before weaving. The fabric is then calendered, for example.
Nach einer bevorzugten Ausführung der Erfindung ist das Gewebe mit einer Folie beschichtet, die einen geringeren Schmelzpunkt als der thermoplastische Kunststoff und/oder das Gewebe besitzt. Das Gewebe kann mit mindestens zwei Folien mit unterschiedlichem Schmelzpunkt beschichtet sei, wobei eine äußere
Folienbeschichtung einen niedrigeren Schmelzpunkt, als eine innere Folienbeschichtung besitzt. Die Folienbeschichtung kann durch Thermokaschierung oder durch Breitschlitzdüsenauftrag erfolgen.According to a preferred embodiment of the invention, the fabric is coated with a film which has a lower melting point than the thermoplastic and / or the fabric. The fabric can be coated with at least two foils with different melting points, one outer Foil coating has a lower melting point than an inner foil coating. The film can be coated by thermal lamination or by using a slot die.
Nach einer Ausführung der Erfindung wird ein beschichtetes Gewebe, das aus gar nicht oder wenig gedrehten, mit Thermoplasten coextrudierten Garnen gewebt oder gewirkt und in einer Art Bügelprozess flachgedrückt, so daß ein dünnes durch und durch beschichtetes Gewebe entsteht, das mit sehr wenig Beschichtungsmasse schon dicht ist und trotzdem extrem dünn ist. Bei leichten dünnen Garnen entspricht die Haftung der Beschichtung fast der Materialfestigkeit des Beschichtungsmaterials, ohne das Gewebe durch Haftvermittler oder Lösungsmittel zu schädigen. Dieses beschichtete Gewebe wird nun mit keiner oder mit mindestens einer bzw. zwei Folien beschichtet. Hierbei dient als luftdichte Schicht die erste Beschichtung. Als Klebeschicht für Schaum dient die innere Schicht. In einer weiteren Version der Erfindung ist das gebügelte und kalandrierte Gewebe schon luftdicht, daß es nur noch einer niederer schmelzenden Klebeschicht bedarf. Bei einer weiteren Ausführungsform der Erfindung ist das gebügelte und kalandrierte Gewebe schon luftdicht und die Beschichtungsmasse so bemessen, daß diese als Klebeschicht für den Schaum dient. Dies ist möglich, da der Schaum während des thermischen Klebevorgangs mit seiner Gitterstruktur nicht durch das Gewebe dringen kann.According to one embodiment of the invention, a coated fabric, which is woven or knitted from yarns that have not been twisted at all, or twisted little, coextruded with thermoplastics, and flattened in a kind of ironing process, so that a thin, thoroughly coated fabric is produced that is already tight with very little coating material is and is still extremely thin. In the case of light, thin yarns, the adhesion of the coating corresponds almost to the material strength of the coating material, without damaging the fabric through adhesion promoters or solvents. This coated fabric is now coated with none or with at least one or two foils. The first coating serves as an airtight layer. The inner layer serves as an adhesive layer for foam. In a further version of the invention, the ironed and calendered fabric is already airtight, so that it only needs a lower melting adhesive layer. In a further embodiment of the invention, the ironed and calendered fabric is already airtight and the coating composition is dimensioned such that it serves as an adhesive layer for the foam. This is possible because the foam with its lattice structure cannot penetrate through the fabric during the thermal bonding process.
Der Vorteil dieser Matte liegt darin, daß durch die Beschichtung die Außenseite der Matte eine eschlossene oder teilweise geschlossene Beschichtung erhält, ohne das Gesamtgewicht wesentlich zu erhöhen. Auf der Außenseite hat dieseThe advantage of this mat is that the coating gives the outside of the mat a closed or partially closed coating without significantly increasing the overall weight. On the outside it has this
Beschichtung eine gute Reibwirkung in Bezug auf den Schlafsack, so daß der Camper auf abschüssigenm Gelände nicht mehr so leicht rutscht. Die Matte kann kein Wasser aufnehmen, bzw muß nicht mit umweltschädlichen Fluor-Carbon- Beschichtungen wasserabweisend gemacht werden. Die Matte läßt sich sehr gut reinigen, was nicht zuletzt im medizinischen Bereich von Vorteil ist. Weiterhin lassen sich auf die Außeseite zusätzliche Aplilkationen aufschweißen ohne das
Gesamtgewicht der Matte durch eine konventionelle zweite Beschichtung schwerer zu machen. Das Gewebe kann leichter gewählt werden, da es nicht durch Lösungsmittel oder Haftvermittler geschwächt wird weiterhin steigt die Durchstoßfestigkeit und die Knickbeständigkeit des Verbundes und damit die Stabilität des der Matte, da Gewebe, die mit Vorbeschichtungen auf Lösungsmittelbasis traditionell eine schlechte Weiterreißfestigkeit haben.Coating has a good friction effect in relation to the sleeping bag, so that the camper no longer slides so easily on sloping terrain. The mat cannot absorb water, or does not have to be made water-repellent with environmentally harmful fluorocarbon coatings. The mat can be cleaned very well, which is not least of advantage in the medical field. Furthermore, additional aplications can be welded onto the outside without this To make the total weight of the mat heavier with a conventional second coating. The fabric can be chosen more easily, since it is not weakened by solvents or adhesion promoters, the puncture resistance and the kink resistance of the composite and thus the stability of the mat increases, since fabrics which traditionally have poor tear resistance with solvent-based precoatings.
Der thermoplastische Kunststoff und das Garn sind vorteilhafterweise flammhemmend ausgeführt.The thermoplastic and the yarn are advantageously made flame-retardant.
Es können zwei Matten durch ein aufgeschweißtes Profil verbunden sein.Two mats can be connected by a welded profile.
Das Gewebe besteht beispielsweise aus Quarzgarn, aus Aramidfaser oder aus modifiziertem Polyester, wie Vektran. Es können hochfeste, an sich schlecht verklebbaren Garne verwendet werden.
The fabric consists, for example, of quartz yarn, aramid fiber or modified polyester, such as Vektran. High-strength yarns which are difficult to glue per se can be used.
