Abstract

The invention relates to an air mattress comprised of at least one air chamber made of strips of an air-tight, water vapor permeable or water vapor impermeable material that are welded or glued together. The air chamber is provided with a closable valve for letting air in and out, and the air chamber is filled with a down feather material or a synthetic fiber insulation material.

Description

Luftmatratzeair mattress
Beschreibungdescription
Die vorliegende Erfindung betrifft eine Luftmatratze mit den Merkmalen des Oberbegriffs das Anspruchs 1.The present invention relates to an air mattress with the features of the preamble of claim 1.
Luftmatratzen, bestehend aus wenigstens einer Luftkammer aus miteinander verschweißten oder verklebten Bahnen eines luftundurchlässigen, wasserdampfdurchlässigen oder -undurchlässigen Materials, wobei die Luftkammer mit einem verschließbaren Ventil zum Ein- und Auslassen von Luft versehen ist, sind bekannt. Die herkömmlichen Luftmatratzen sind zwar bequem, sie wärmen jedoch nur minimal, da die in den Luftkammern oder der Luftkammer eingeschlossene Luft frei zirkulieren kann und damit durch Konvention viel Wärme abführt. Luftmatratzen aus umhülltem Schaumstoff sind relativ schwer, haben ein großes Packmaß und sind relativ teuer in der Herstellung, da Delaminationsproblemen der Umhüllung gegenüber dem Schaumstoff vorgebeugt werden muss.Air mattresses, consisting of at least one air chamber made of welded or glued webs of an air-impermeable, water vapor-permeable or impermeable material, the air chamber being provided with a closable valve for admitting and discharging air, are known. The conventional air mattresses are comfortable, but they only warm up minimally, because the air trapped in the air chambers or the air chamber can circulate freely and, by convention, dissipates a lot of heat. Air mattresses made of covered foam are relatively heavy, have a large pack size and are relatively expensive to manufacture, since delamination problems of the cover with respect to the foam must be prevented.
Aufgabe der vorliegenden Erfindung ist es, eine Luftmatratze zu schaffen, die einen Wärmeverlust durch Konvektion minimiert, die jedoch trotzdem leicht ist, klein verpackt werden kann und günstig in der Herstellung ist.The object of the present invention is to provide an air mattress which minimizes heat loss through convection, but which is nevertheless light, can be packaged small and is inexpensive to manufacture.
Diese Aufgabe wird mit den in Anspruch 1 genannten Merkmalen gelöst. Vorteilhafte Ausfuhrungen und Weiterentwicklungen der Erfindung sind in den weiteren Ansprüchen umfaßt.This object is achieved with the features mentioned in claim 1. Advantageous embodiments and further developments of the invention are included in the further claims.
Erfindungsgemäß ist eine Luftmatratze, bestehend aus wenigstens einer Luftkammer aus miteinander verschweißten oder verklebten Bahnen eines luftundurchlässigen, wasserdampfdurchlässigen oder -undurchlässigen Materials, wobei die Luftkammer mit einem verschließbaren Ventil zum Ein- und Auslassen von Luft versehen ist, dadurch gekennzeichnet, dass die Luftkammer mit einem Daunenmaterial oder einem Kunstfaserisolationsmaterial gefüllt ist.According to the invention, an air mattress consisting of at least one air chamber made of welded or glued webs of an air-impermeable, water vapor-permeable or impermeable material, wherein the air chamber is provided with a closable valve for admitting and discharging air, characterized in that the air chamber is filled with a down material or a synthetic fiber insulation material.
Nach einer bevorzugten Ausführung der Erfindung ist die Luftkammer durch Stege unterteilt, wobei die Stege an den unteren und oberen großen Flächen des Luftmatratzenmaterials unmittelbar oder über Bänder oder dergleichen befestigt sind. Die Stege, die das Füllmaterial in ausgeglichener Verteilung halten, sind bei größeren Kammern vorzugsweise luftdurchlässig und bestehen beispielsweise aus Trikotnylon. Sie können aber auch luftundurchlässig sein, wenn eine Unterteilung in unabhängige Kammern erwünscht ist.According to a preferred embodiment of the invention, the air chamber is divided by webs, the webs being fastened to the lower and upper large surfaces of the air mattress material directly or via bands or the like. The bars, which keep the filling material in a balanced distribution, are preferably air-permeable in larger chambers and consist, for example, of tricot nylon. However, they can also be impermeable to air if a division into independent chambers is desired.
Vorzugsweise sind sind die Stege oder die Bänder oder dergleichen mit dem Luftmatratzenmaterial verschweißt oder verklebt. Die Stege sind im wesentlichen regelmäßig angeordnet und sind senkrecht oder schräg zur horizontalen Liegefläche der Luftmatratze angeordnet.The webs or the bands or the like are preferably welded or glued to the air mattress material. The webs are arranged essentially regularly and are arranged perpendicularly or obliquely to the horizontal lying surface of the air mattress.
Vorteilhafterweise ist das, oder sind die Ventile mit einem offenporigen Material zur Verhinderung des Austritts von Daunen- oder Kunstfaserisolationsmaterials unterlegt. Ein Aufblasen der Luftmatratze mit dem Mund ist nicht erwünscht, da so Feuchtigkeit in das eingelegte Daunen- oder Kunstfasermaterial eingebracht wird. In ansich bekannter Weise ist das Ventil ein Sicherheitsventil zum Verhindern des Ausströmens von Luft. Das Ventil ist mit einer Pumpvorrichtung oder Blasebalgvorrichtung verbindbar, wobei diese Vorrichtung nach einer besonderen Ausfuhrung der Erfindung aus einer flexiblen, mit einem Einlassventil versehenen Hülle besteht, wobei diese Hülle mit einem offenporigen, selbst expandierenden Schaumstoff gefüllt ist.This is advantageously, or the valves are underlaid with an open-pore material to prevent the escape of down or synthetic fiber insulation material. It is not desirable to inflate the air mattress with your mouth, as this will introduce moisture into the down or synthetic fiber material. In a manner known per se, the valve is a safety valve for preventing the escape of air. The valve can be connected to a pump device or bellows device, this device according to a particular embodiment of the invention consisting of a flexible sleeve provided with an inlet valve, this sleeve being filled with an open-pore, self-expanding foam.
Im folgenden wird die Erfindung anhand einer Zeichnungen beispielhaft näher beschrieben.In the following the invention is described in more detail by way of example with reference to drawings.
Fig. 1 zeigt eine Luftmatratze 1 , die vorne im Schnitt dargestellt ist. Die Luftmatratze 1 ist mit einem Füllmaterial 2 aus Daunen oder Kunstfaserwatte gefüllt. Diese Füllmaterial ist leicht und lässt sich extrem komprimieren, so dass bei Wahl eines leichten Hüllstoffes sich ein kleines Packmaß und ein geringes Gewicht ergeben. Die Luftmatratze 1 ist durch senkrecht angeordnete Stege 3, die oben und unten beispielsweise durch Verschweißen mit dem Hüllmaterial verbunden sind, in gleichmäßige Rippen unterteilt. Die Stege 3 dienen dazu, das Füllmaterial an Ort und Stelle zu halten. In der gezeigten Ausführung ist die Luftmatratze eine Einkammermatratze mit einem Ventil 4, so dass die Stege 3 aus einem luftdurchlässigen Material bestehen, um das Aufblasen und Ablassen von Luft zu ermöglichen. Vorteilhafterweise ist das Ventil 4 ein Sicherheitsventil mit einer Ausströmsicherung, das aber zum Veφacken geöffnet werden kann, bzw. um das Komprimieren zu erleichtern, sogar umgeschaltet werden kann, so dass Luft nur ausströmen, aber nicht wieder einströmen kann. Fig. 1 shows an air mattress 1, which is shown in section at the front. The air mattress 1 is made of a filling material 2 made of down or synthetic fiber wadding filled. This filling material is light and can be extremely compressed, so that when you choose a light wrapping material, you get a small pack size and a low weight. The air mattress 1 is divided into uniform ribs by vertically arranged webs 3, which are connected to the covering material at the top and bottom, for example by welding. The webs 3 serve to hold the filling material in place. In the embodiment shown, the air mattress is a single-chamber mattress with a valve 4, so that the webs 3 are made of an air-permeable material in order to enable the inflation and deflation of air. Advantageously, the valve 4 is a safety valve with an outflow protection, but which can be opened for packaging, or to facilitate compression, can even be switched over, so that air can only flow out but not flow back in again.
