A foam mattress (1) with two foam plates (2, 3) positioned above each other, which respectively have on their surfaces pointing towards each other, a profile extending over the total width of the mattress with equal spacings in each case from the profile tips (4, 6) and profile valleys (5, 7), and the two foam plates (2, 3) are loosely placed on each other such that the profile tips (4) of one foam plate (2) project into the profile valleys (7) of the other foam plate (3), whereby the profile of the two foam plates (2, 3) runs corresponding to a sinus-shaped wavy line, the wavy line of one foam plate (2) having a greater amplitude than the wavy line of the other foam plate (3), and the wave peaks (4) of the foam plate (2) with the wavy line of greater amplitude lying with its tips at the deepest point of the wave valleys (7) of the foam plate (3) with the wavy line of smaller amplitude.

Description

Die Erfindung betrifft eine Matratze aus Schaumstoff mit zwei übereinanderliegenden Schaumstoffplatten, die auf ihren einander zugewandten Flächen je eine wellenförmige Profilierung mit jeweils gleichem Abstand von Wellenbergen und Wellentälern aufweisen.The invention relates to a mattress made of foam with two superimposed foam sheets, each of which has a wave-shaped profile on their mutually facing surfaces with the same distance from wave crests and wave troughs.

Eine derartige Schaumstoffmatratze ist aus dem DE-GM 17 23 269 bekannt. Dabei ist jedoch zwischen die beiden symmetrischen Profilschnitte eine weitere ebene Schaumstoffplatte gelegt, die bewirkt, daß die beiden profilierten Schaumstoffplatten nur mit ihren Wellenbergen tragen und somit eine weichere Abfederung gewährleisten. Eine derartige Matratze ist jedoch sehr aufwendig und bedingt eine relativ große Bauhöhe, damit die Zwischenplatte überhaupt eine Wirkung zeigt.Such a foam mattress is known from DE-GM 17 23 269. However, a further flat foam sheet is placed between the two symmetrical profile cuts, which means that the two profiled foam sheets only support with their wave crests and thus ensure a softer cushioning. However, such a mattress is very complex and requires a relatively large height so that the intermediate plate has an effect at all.

Ferner ist aus der DE-AS 28 56 758 eine Matratze aus Schaumstoff bekannt, bei der einzelne T-förmige Stege mit T-förmigen Ausnehmungen abwechseln, wobei die offene Seite mit einer glatten Platte abgedeckt ist. Eine derartige Matratze bietet zwar auch einen guten Federungskomfort, jedoch ist, um die Matratze voll zur Wirkung zu bringen, ein gesonderter auf die Abstände der Stege abgestimmter Lattenrost erforderlich.Furthermore, from DE-AS 28 56 758 a mattress made of foam is known in which individual T-shaped webs alternate with T-shaped recesses, the open side being covered with a smooth plate. Such a mattress also offers good suspension comfort, but in order to bring the mattress to full effect, a separate slatted frame is required which is matched to the spacing of the webs.

Demgegenüber liegt der vorliegenden Erfindung die Aufgabe zugrunde, eine Matratze zu schaffen, die guten Federungskomfort bietet und die in ihrer Härte einfach auf die jeweilige Belastung abstimmbar ist, wobei mit ein und derselben Matratze die Einstellung von zwei verschiedenen Härten möglich ist.Außerdem soll die Matratze eine gute Querbelüftung aufweisen. Ausgehend vom dem eingangs genannten Stand der Technik ist daher zur Lösung der gestellten Aufgabe erfindungsgemäß vorgesehen, daß die wellenförmige Profilierung der einen Platte eine geringere Tiefe als die Profilierung der anderen Platte aufweist und daß die beiden Platten lose so aufeinandergelegt sind, daß die Wellenberge der einen Platte in die Wellentäler der anderen Platte ragen.In contrast, the present invention has for its object to provide a mattress that offers good suspension comfort and the hardness of which can be easily adjusted to the respective load, with the same mattress being able to set two different levels of hardness have good cross ventilation. Based on the prior art mentioned at the outset, it is therefore provided according to the invention to achieve the object that the wavy profiling of one plate has a smaller depth than the profiling of the other plate and that the two plates are loosely placed on top of one another so that the wave crests of one Extend plate into the troughs of the other plate.

Dabei verbleiben zwischen den Wellenbergen der Platte mit der flacheren Profilierung und den Wellentälern der Platte mit der tieferen Profilierung sich über die gesamte Breite der Matratze erstreckende Hohlkanäle, die eine gute Belüftung bewirken.This leaves between the wave crests of the plate with the flatter profile and the troughs of the plate with the deeper profile extending over the entire width of the mattress hollow channels, which provide good ventilation.

Die beiden Platten können dabei unterschiedliche Stauchhärte und/oder unterschiedliches Raumgewicht aufweisen, womit eine zusätzliche Variation der Härte möglich ist. Zweckmäßigerweise weist dabei die Platte mit der flacheren Profilierung die größere Stauchhärte auf und ist als Unterplatte angeordnet.The two plates can have different compression hardness and / or different density, which makes an additional variation in hardness possible. The plate with the flatter profiling expediently has the greater compression hardness and is arranged as a lower plate.

Mit einer derartigen Matratze kann also eine auf die jeweilige Belastung genau abgestimmte Abfederung erreicht werden, wobei - je nachdem welche Matratzenseite untenliegt - die Matratze einen weicheren oder härteren Eindruck macht.With a mattress of this type, a cushioning that is precisely matched to the respective load can be achieved, the mattress making a softer or harder impression, depending on which side of the mattress is underneath.

Um darüber hinaus eine weitere Anpassung,insbesondere an äußere Belastungen oder ein gewünschtes härteres Verhalten der Matratze zu gewährleisten, ist es möglich, daß die untenliegende Platte größerer Stauchhärte im mittleren Bereich der Hauptbelastung einen Einsatz aus Schaumstoff von zusätzlich größerer Stauchhärte aufweist.In addition, to ensure further adaptation, in particular to external loads or a desired harder behavior of the mattress, it is possible that the lower plate of greater compression hardness in the central region of the main load has an insert made of foam of an additionally greater compression hardness.

Ein weiterer wesentlicher Vorteil der so gestalteten Matratze ergibt sich dadurch, daß bei einem entsprechenden symmetrischen Verlauf der Profilierungen aus einer quaderförmigen Grundplatte durch einen einzigen Schnitt jeweils zwei Oberplatten oder zwei Unterplatten gleicher Profilierung ohne Abfall fertigbar sind. Anhand einer schematischen Zeichnung sind Aufbau und Wirkungsweise einer Matratze nach der Erfindung näher erläutert. In der einzigen Figur ist dabei ein Längsschnitt durch einen Teil der Matratze dargestellt.Another major advantage of the mattress designed in this way is that, with a corresponding symmetrical profile of the profiles from a rectangular base plate, two top plates or two bottom plates of the same profile can be produced without waste by a single cut. The structure and mode of operation of a mattress according to the invention are explained in more detail using a schematic drawing. In the single figure, a longitudinal section through part of the mattress is shown.

Nachdem dargestellten Ausführungsbeispiel besteht die Matratze 1 aus einer oberen Schaumstoffplatte 2 und einer unteren Schaumstoffplatte 3. Die obere Schaumstoffplatte 2 weist dabei eine wellenförmige Profilierung mit Wellenbergen 4 und Wellentälern 5 auf, während die untere Platte 3 mit einer wellenförmigen Profilierung geringerer Höhe mit den Wellenbergen 6 und den Wellentälern 7 versehen ist. Die beiden Schaumstoffplatten 2 und 3 sind nun so aufeinandergelegt, daß jeweils die Wellenberge 4 bzw. 6 in die Wellentäler 5 bzw. 7 der jeweils gegenüberliegenden Platte ragen. Da nun die untere Platte 3 eine Profilierung geringerer Höhe aufweist, verbleiben zwischen den Wellenbergen 6 dieser unteren Platte und dem Grund der Wellentäler 5 der oberen Platte 2 Hohlkanäle 8, die sich über die gesamte Breite der Matratze 1 erstrecken.According to the exemplary embodiment shown, the mattress 1 consists of an upper foam sheet 2 and a lower foam sheet 3. The upper foam sheet 2 has an undulating profile with wave crests 4 and wave troughs 5, while the lower plate 3 with an undulating profile of lower height with the wave crests 6 and the troughs 7 is provided. The two foam sheets 2 and 3 are now placed one on top of the other so that the crests 4 and 6 respectively protrude into the troughs 5 and 7 of the opposite plate. Since the lower plate 3 now has a lower profile, hollow channels 8 remain between the crests 6 of this lower plate and the bottom of the troughs 5 of the upper plate 2, which extend over the entire width of the mattress 1.

Im allgemeinen ist der Aufbau der Matratze so gewählt, daß die untere Platte 3 eine größere Stauchhärte als die obere Platte 2 - im allgemeinen jedoch bei gleichem Raumgewicht - aufweist.In general, the structure of the mattress is selected so that the lower plate 3 has a greater compression hardness than the upper plate 2 - but generally with the same density.

Bei einer Belastung der Matratze ergibt sich somit eine progressive Federkennlinie da - entsprechend dem dargestellten Ausführungsbeispiel - zunächst nur die Wellenberge 5 der weicheren Platte 2 tragen. Wenn dann diese Wellenberge 4 soweit zusammengedrückt sind, daß die Wellentäler 5 mit den Wellenbergen 6 der unteren Platte.3 in Berührung kommen,und damit immer mehr Schaumstoff der oberen Platte und der unteren Platte zusammengedrückt wird, ergibt sich somit eine,äbhängig von der Form und der Weite der Profilierung,steifer werdende Federung. Wenn schließlich die Kanäle 8 ganz zusammengedrückt sind, trägt das gesamte Schaumstoffmaterial der oberen Platte 2 und das Material der unteren Platte 3. Da insgesamt das Schaumstoffmaterial entsprechend der jeweiligen diskreten Belastung unterschiedlich eingedrückt wird, ergibt sich insgesamt mit einer derartigen Matratze eine optimale punktelastische Abstützung.When the mattress is loaded, there is a progressive spring characteristic since - in accordance with the exemplary embodiment shown - initially only the wave crests 5 of the softer plate 2 are carried. If these wave crests 4 are then compressed so far that the wave troughs 5 come into contact with the wave crests 6 of the lower plate 3, and thus more and more foam of the upper plate and the lower plate is compressed, this results in one, depending on the shape and the width of the profiling, stiffer suspension. Finally, when the channels 8 are completely compressed, the entire foam material of the upper plate 2 and the material of the lower plate 3 are supported. With such a mattress there is an overall optimal elastic support.

Durch die beschriebene Ausbildung der Matratze und die relativ geringen Abstände der Wellenberge bzw. Wellentäler voneinander ist für die volle Wirkungsweise der Matratze auch ein speziell auf die Lage der einzelnen Profilierungen abgestimmter Lattenrost nicht erforderlich, sondern es kann im Grunde jede beliebige Unterlage benutzt werden. Ein weiterer Vorteil dieser Matratze besteht darin, daß durch die dauernde Querschnittsveränderung der Hohlkanäle 8 eine gute Querbelüftung der Matratze gewährleistet ist, so daß ein evtl. Stau von Feuchtigkeit und Wärme sicher vermieden wird.Due to the described design of the mattress and the relatively small distances between the wave crests or troughs from one another, a slatted frame specially tailored to the position of the individual profiles is not necessary for the full operation of the mattress, but basically any base can be used. Another advantage of this mattress is that the constant change in cross-section of the hollow channels 8 ensures good cross-ventilation of the mattress, so that a possible build-up of moisture and heat is safely avoided.

Um die Wirkungsweise der beiden aufeinanderliegenden Platten 2 und 3 zu optimieren, sind diese Platten nur lose aufeinandergelegt. Zur zusätzlichen Verbindung kann dann lediglich an den Stirnseiten ein querverlaufender Schaumstoffbalken 9 mit den beiden Stirnseiten der Platten 2 und 3 verklebt werden.In order to optimize the mode of operation of the two plates 2 and 3 lying one on top of the other, these plates are only placed loosely on top of one another. For the additional connection, a transverse foam bar 9 can then be glued to the two end faces of the plates 2 and 3 only on the end faces.

Für eine noch härtere Charakteristik der Matratze ist es dabei möglich, insbesondere in den hochbelasteten Bereichen in der unteren Platte 3,etwa zwischen den gestrichelten Linien 1O einen Schaumstoff abschnitt mit noch höherer Stauchhärte und evtl. höherem Raumgewicht einzusetzen.For an even harder characteristic of the mattress, it is possible to use a foam section with an even higher compression hardness and possibly higher density, especially in the highly stressed areas in the lower plate 3, for example between the dashed lines 10.

Durch die symmetrische Profilierung der beiden Platten ist auch eine abfallose Herstellung dieser Matratzen möglich, da dann durch einen einzigen wellenförmigen Schnitt aus einem quaderförmigen Schaumstoffblock jeweils 2 gleichartige Oberplatten 2 bzw. Unterplatten 3 anfallen.Due to the symmetrical profiling of the two plates, a waste-free production of these mattresses is also possible, since then two identical top plates 2 and bottom plates 3 are obtained from a cuboid foam block through a single undulating cut.

Durch die Verwendung von Schaumstoff unterschiedlicher Stauchhärte gleichen oder unterschiedlichen Raumgewichtes oder aber auch unterschiedlichen Raumgewichtes allein, lassen sich somit auch unterschiedliche Härten und Federkennlinien der Matratze einstellen. Da die Matratze bei gleicher Wirkungsweise beidseitig benutzbar ist, stellt sich dann auch jeweils ein unterschiedliches Härtegefühl ein, je nachdem, ob der Schaumstoff mit der weicheren oder der härteren Stauchhärte oben liegt.By using foam of different compression hardness of the same or different density or also different density alone, different hardness and spring characteristics of the mattress can be set. Since the mattress works the same way can be used on both sides, there is also a different feeling of hardness, depending on whether the foam with the softer or the harder compression hardness is on top.

Bei dem in Fig. 2 dargestellten Ausführungsbeispiel, das einen Blick auf die untere Platte 14 einer Matratze 11 zeigt, weisen sowohl die Wellenberge 12 als auch die Wellentäler 13 einen V-förmigen Verlauf auf, wobei die V-Spitzen 15 in der Mitte der Matratzenbreite liegen. Auch hierbei sind die beiden Platten so aufeinandergelegt, daß die Wellenberge der einen Platte in die Wellentäler der anderen Platte ragen. Bei dieser Gestaltung ergeben sich ebenfalls durchgehende Kanäle für eine gute Durchlüftung. Zusätzlich hat diese Matratze noch den Vorteil, daß sie im mittleren Bereich wegen der dort vorhandenen Materialanhäufung härter ist als in den Seitenbereichen. Die Herstellung dieser Matratze ist dabei die gleiche wie bei der mit gerade durchgehender Profilierung.In the embodiment shown in FIG. 2, which shows a view of the lower plate 14 of a mattress 11, both the wave crests 12 and the wave troughs 13 have a V-shaped course, with the V-tips 15 in the middle of the mattress width lie. Here, too, the two plates are placed one on top of the other in such a way that the wave crests of one plate protrude into the troughs of the other plate. With this design, there are also continuous channels for good ventilation. In addition, this mattress has the advantage that it is harder in the middle area because of the material accumulation there than in the side areas. The manufacture of this mattress is the same as that of the straight profile.
