Description

Die Erfindung bezieht sich auf ein selbst aufblasendes Polster, insbesondere Liegematte, mit einer Schaumstoffplatte aus offenzelligem Polyurethan-Weichschaum, die beidseitig und am Rand mit luftdichten Deckbahnen verklebt ist, sowie mit einem Luftventil an einer Seitenkante.The invention relates to a self-inflating cushion, in particular a lying mat, with a foam sheet made of open-cell polyurethane soft foam, which is glued on both sides and at the edge with airtight cover sheets, and with an air valve on one side edge.

Derartige Polster, die meist in Form von Liegematten verwendet werden, sind aus der US-A-4 261 776 bekannt. Sie weisen im allgemeinen eine Größe von etwa 190 x 60 cm und eine Dicke von 20 bis 50 mm auf. Da sie sich im unbenutzten Zustand sehr eng zusammenrollen lassen, eignen sie sich wegen ihres geringen Transportvolumens besonders gut für Wanderer und Bergsteiger.Such cushions, which are mostly used in the form of lying mats, are known from US-A-4,261,776. They generally have a size of approximately 190 x 60 cm and a thickness of 20 to 50 mm. Since they can be rolled up very tightly when not in use, they are particularly suitable for hikers and mountaineers due to their small transport volume.

Zur Benutzung wird dabei einfach das meist seitlich angebrachte Ventil geöffnet, wobei durch das Expansionsbestreben des eingeschlossenen Schaumstoffs die Liegematte selbst ausrollt und Luft in die Matte eingesaugt wird, so daß sie sich damit selbsttätig glättet und eine Form und ein Volumen annimmt, wie es dem des expandierten Schaumstoffes entspricht. Nach dem Füllen mit Luft wird das Ventil - gegebenenfalls nach weiterem zusätzlichen Einblasen von Luft - geschlossen. Damit kann die Luft nicht mehr entweichen und das Polster oder die Matte sind gebrauchsfähig und bieten insbesondere eine gute Wärmeisolierung und Polsterung gegenüber dem Boden, auf dem sie ausgelegt sind.To use it, the valve, which is usually attached to the side, is simply opened, whereby the expansion mat of the enclosed foam unrolls the mat itself and draws air into the mat, so that it automatically smoothes and takes on a shape and volume as it desires expanded foam corresponds. After filling with air, the valve is closed - if necessary after further blowing in air. This means that the air can no longer escape and the upholstery or mat can be used and in particular offers good thermal insulation and upholstery from the floor on which they are laid out.

Wesentlich bei einem solchen Polster ist, daß es neben guten Gebrauchs- und Isolationseigenschaften auch möglichst leicht ist und sich zu einer dünnen Rolle zusammenrollen läßt. Im allgemeinen wird dabei ein Kompromiß zwischen einer ausreichenden Isolierungs- und Dämpfungswirkung für die daraufliegende Person und der Dicke der erforderlichen Schaumstoffbahn getroffen.It is essential with such an upholstery that, in addition to good use and insulation properties, it is also as light as possible and can be rolled up into a thin roll. In general, a compromise is made between a sufficient insulation and damping effect for the person lying on it and the thickness of the required foam sheet.

Der vorliegenden Erfindung liegt daher die Aufgabe zugrunde, ein Polster und insbesondere eine Liegematte der eingangs beschriebenen Art so auszugestalten, daß mindestens unter Beibehaltung des vorhandenen Komforts noch zusätzlich eine Gewichtsreduzierung möglich ist, so daß dadurch das Handling noch weiter verbessert wird.The present invention is therefore based on the object of designing a cushion and, in particular, a lying mat of the type described at the outset in such a way that a reduction in weight is also possible, at least while maintaining the existing comfort, so that the handling is thereby further improved.

Zur Lösung dieser Aufgabe ist erfindungsgemäß vorgesehen, daß die Schaumstoffplatte parallel zur Ober- und Unterseite verlaufende, durchgehende Durchbrechungen aufweist, die etwa in mittlerer Höhe der Dicke der Schaumstoffplatte verlaufen, und durch die durchgehenden Deckbahnen abgedeckt sind.To achieve this object, it is provided according to the invention that the foam sheet has continuous openings running parallel to the top and bottom, which run approximately in the middle of the thickness of the foam sheet, and are covered by the continuous cover sheets.

Mit derartigen Durchbrechungen läßt sich das Gewicht des Polsters oder der Matte noch erheblich reduzieren, ohne daß dadurch die Gebrauchseigenschaften in irgendeiner Weise leiden.With such breakthroughs, the weight of the cushion or mat can be significantly reduced without the performance properties in any way suffering.

Zweckmäßigerweise weisen die Durchbrechungen einen Durchmesser von nicht mehr als einem Drittel der Schaumstoffplatte auf.The openings advantageously have a diameter of not more than one third of the foam sheet.

Dabei können sich diese Durchbrechungen quer zur Längserstreckung, in Richtung der Längserstreckung oder auch sowohl in Längs- und Querrichtung der Schaumstoffplatte erstrecken.These openings can extend transversely to the longitudinal extension, in the direction of the longitudinal extension or both in the longitudinal and transverse directions of the foam sheet.

Eine weitere Möglichkeit besteht darin, daß die Durchbrechungen im Winkel zur Längserstreckung des Polsters verlaufen.Another possibility is that the openings run at an angle to the longitudinal extension of the cushion.

Eine weitere Möglichkeit der Ausgestaltung besteht darin, daß die Schaumstoffplatte mittig in zwei übereinanderliegende Schichten geteilt ist, deren mindestens eine Berührungsfläche durchgehende Durchbrechungen bildende Profilierungen aufweist.A further possible embodiment is that the foam plate is divided in the middle into two layers one above the other, the at least one contact surface of which has continuous perforations.

Dabei können beide aufeinanderliegenden Berühungsflächen der Schaumstoffschichten je eine Profilierung aufweisen.Both contact surfaces of the foam layers lying one on top of the other can each have a profiling.

Zweckmäßigerweise ist diese Profilierung angenähert wellenförmig mit sich über die gesamte Länge und/oder Breite der Berührungsflächen erstreckenden Wellen ausgebildet.This profiling is expediently approximately wavy with waves extending over the entire length and / or width of the contact surfaces.

Die Profilierung von Ober- und Unterschicht kann dabei parallel zueinander verlaufen derart, daß jeweils die Wellenberge beider Profilierungen aufeinanderliegen.The profiling of the upper and lower layers can run parallel to one another in such a way that the wave crests of both profiles lie on top of one another.

Es ist aber auch möglich, daß die Profilierungen von Ober- und Unterschicht im Winkel zueinander verlaufen und sich kreuzende Durchbrechungen bilden.But it is also possible that the profiles of the upper and lower layers run at an angle to one another and form intersecting openings.

Dabei können die Profilierungen von Ober- und Unterschicht jeweils unterschiedliche Form und/oder Größe aufweisen.The profiles of the upper and lower layers can each have a different shape and / or size.

Zur weiteren Optimierung ist es möglich, daß Ober- und Unterschicht der Schaumstoffplatten aus Materialien unterschiedlicher Härte bestehen.For further optimization, it is possible that the top and bottom layers of the foam sheets consist of materials of different hardness.

Damit wird also nicht nur eine Gewichtsreduzierung erreicht, sondern es ist auch eine individuelle Komfortanpassung möglich.So not only is weight reduction achieved, but individual comfort adjustment is also possible.

The structure and mode of operation of exemplary embodiments according to the invention are explained in more detail with reference to a schematic drawing. Show:

Wie man aus Fig. 1 ersieht, ist eine rechteckige Schaumstoffplatte 10 mit durchgehenden Kanälen 11 versehen, die sich quer zur Längserstreckung der Schaumstoffplatte erstrecken. Es ist aber auch möglich, Kanäle 12 in Längsrichtung der Schaumstoffplatte 10 vorzusehen. Wenn dabei die Kanäle 11 und 12 in beiden Richtungen und sich einander kreuzend vorgesehen werden, ist damit eine noch weitgehendere Material- und damit Gewichtsreduzierung möglich.As can be seen from Fig. 1, a rectangular foam sheet 10 is provided with continuous channels 11 which are transverse to the longitudinal extension of the foam sheet extend. However, it is also possible to provide channels 12 in the longitudinal direction of the foam sheet 10. If the channels 11 and 12 are provided in both directions and crossing each other, an even more extensive material and thus weight reduction is possible.

Zweckmäßigerweise sind diese Kanäle 11 bzw. 12 in etwa mittlerer Höhe der Schaumstoffplatte 10 vorgesehen. Ihr Durchmesser sollte dabei nicht mehr als ein Drittel der Schaumstoffplatte betragen. Neben einer exakt längs- oder querverlaufenden Anordnung dieser Kanäle 11 und 12 ist aber auch ein Verlauf im Winkel zur Längserstreckung, entweder nur in einer Richtung oder auch in sich kreuzenden Richtungen möglich.These channels 11 and 12 are expediently provided at approximately the middle height of the foam sheet 10. Their diameter should not be more than a third of the foam sheet. In addition to an exactly longitudinal or transverse arrangement of these channels 11 and 12, a course at an angle to the longitudinal extent is also possible, either only in one direction or in intersecting directions.

In Fig. 2 ist diese Schaumstoffplatte im Längsschnitt dargestellt, wobei auch die luftdicht gummierten Deckbahnen 2 und 3 eingezeichnet sind, die auf Ober- und Unterseite der Schaumstoffplatte 10 verklebt sind. Der seitlich überstehende Rand 4 dieser Deckbahnen 2 und 3 ist ebenfalls luftdicht miteinander verklebt. An einer Ecke einer solchen Matte ist ein nicht näher dargestelltes, die beiden Deckbahnen 2 und 3 durchdringendes Ventil eingesetzt, um die Matte mit Luft zu füllen bzw. die Luft aus der Matte herauszudrücken.In Fig. 2, this foam sheet is shown in longitudinal section, the airtight rubberized cover sheets 2 and 3 are also shown, which are glued to the top and bottom of the foam sheet 10. The laterally projecting edge 4 of these cover sheets 2 and 3 is also glued airtight together. At one corner of such a mat, a valve, not shown, penetrating the two cover sheets 2 and 3 is used to fill the mat with air or to push the air out of the mat.

Mit einer solchen Anordnung von Kanälen 11 und/oder 12 läßt sich wegen der Reduzierung der Schaumstoffmasse diese hatte nach Gebrauch auch dünner zusammenrollen, da nicht mehr soviel Schaumstoffmaterial zusammengepreßt werden muß.With such an arrangement of channels 11 and / or 12, because of the reduction in the foam mass, it could also roll up thinner after use, since no more foam material has to be pressed together.

Eine weitere Möglichkeit der Gewichtsreduzierung ergibt sich durch eine Gestaltung der Matte, wie sie in Fig. 3 dargestellt ist. Dabei ist die Schaumstoffplatte 20 mittig geteilt und besteht aus den beiden aufeinanderliegenden Schichten 21 und 22, die ungefähr jeweils gleiche Dicke aufweisen können. Die Berührungsflächen der beiden Schaumstoffschichten 21 und 22 sind nach dem dargestellten Ausführungsbeispiel mit einer Profilierung 23 bzw. 24 versehen. Diese Profilierungen 23 und 24 sind bei dem dargestellten Ausführungsbeispiel wellenförmig und zwar annähernd entsprechend einer Sinuslinie ausgebildet, wobei die Profilierungen 23 und 24 im rechten Winkel zueinander verlaufen, so daß sich jeweils kreuzende Wellenberge und Wellentäler ergeben.Another way of reducing weight results from a design of the mat as shown in FIG. 3. The foam sheet 20 is divided in the middle and consists of the two layers 21 and 22 lying on top of one another, which can each have approximately the same thickness. The contact surfaces of the two foam layers 21 and 22 are provided with a profile 23 and 24 according to the illustrated embodiment. These profiles 23 and 24 are wave-shaped in the illustrated embodiment, approximately corresponding to a sine line, the profiles 23 and 24 being at right angles to one another, so that each intersecting wave crests and wave troughs result.

Bei einer solchen Ausgestaltung ergibt sich eine Materialersparnis von etwa 25%, d.h. die Matte ist bei gleicher Stärke wie eine unprofilierte Matte etwa 25% leichter.With such a configuration, there is a material saving of about 25%, i.e. the mat is about 25% lighter with the same thickness as an unprofiled mat.

Bei einer Schaumstoffplatte 20 mit einer Gesamtstärke von mindestens 15 bis 20 mm sollte die Profilierungsbreite, d.h. der Abstand zweier Wellenberge voneinander, nicht weniger als 5 mm betragen. Maßgebend für Größe und Art der Profilierung ist im wesentlichen auch der angestrebte Komfort dieser Matte, d.h. die Profilierungen dürfen nicht so groß sein, daß dadurch ein Komfortabfall oder ein Durchdrücken der Matte erfolgt.In the case of a foam sheet 20 with a total thickness of at least 15 to 20 mm, the profiling width, ie the distance between two wave crests from one another, should not be less than 5 mm. Decisive for the size and type of profiling is essentially the desired comfort of this mat, ie the profiling must not be so large that it causes a drop in comfort or the mat is pushed through.

Entgegen des dargestellten angenähert sinusförmigen Verlaufes der Profilierungen 23 und 24 ist aber auch jede andere wellenförmige oder auch eine keilförmige Gestaltung denkbar. Dabei können die Profilierungen in jedem Winkel zueinander, d.h. beispielsweise auch schräg zueinander liegen und bis zum Extremfall eines Parallelverlaufes angeordnet sein. Wenn dabei die Profilierung der beiden Schichten 21 und 22 in gleicher Richtung verläuft, sollte sie dann auch die gleiche Größe und Konfiguration aufweisen, so daß jeweils die Wellenberge von Ober- und Unterschicht aufeinander liegen.Contrary to the approximately sinusoidal profile 23 and 24 shown, any other wave-shaped or wedge-shaped configuration is also conceivable. The profiles can be at any angle to each other, i.e. for example, also lie obliquely to one another and be arranged up to the extreme case of a parallel course. If the profiling of the two layers 21 and 22 runs in the same direction, it should then also have the same size and configuration, so that the wave crests of the upper and lower layers lie one on top of the other.

Für eine zusätzliche Komforterhöhung können ferner Oberschicht 21 und Unterschicht 22 jeweils aus einem Material unterschiedlicher Beschaffenheit, d.h. insbesondere unterschiedlicher Härte, bestehen, so daß - je nachdem welche Schicht oben liegt - ein weicheres oder härteres Polsterverhalten gegeben ist.For an additional increase in comfort, top layer 21 and bottom layer 22 can also each be made of a material of different properties, i.e. in particular different hardness, so that - depending on which layer is on top - there is a softer or harder cushioning behavior.

Selbstverständlich ist es auch möglich, daß nur eine der beiden Schichten 21 bzw. 22 mit einer Profilierung versehen und die andere Schicht auf ihrer Berührungsfläche glatt ausgebildet ist.Of course, it is also possible for only one of the two layers 21 and 22 to be profiled and for the other layer to be smooth on its contact surface.

Ingesamt ergibt sich also ein Polster in Form eines Sitzkissens oder einer Liegematte, das sich selbst aufbläst und ohne Komforteinbuße ein erheblich geringeres Gewicht und damit auch im eingerollten Zustand ein geringeres Packmaß aufweist als Matten herkömmlicher Gestaltung.All in all, there is a cushion in the form of a seat cushion or a lying mat that inflates itself and has a considerably lower weight without sacrificing comfort, and thus also has a smaller pack size than rolled-up mats in the rolled-up state.
