Abstract

The invention relates to a mattress (1) comprising a block made of elastic polyurethane soft foam material. In order to achieve optimum punctiform surface characteristics, the mattress is provided at least on one of the two surfaces (2, 3) with parallel incisions (4, 5, 6, 7, 8) both in the longitudinal direction and in the transverse direction, the depth of which incisions is about one quarter to one third of the thickness of the mattress. <IMAGE>

Description

Die Erfindung bezieht sich auf eine Matratze aus einem Block aus elastischem Polyurethan-Weichschaumstoff, die zumindest auf einer der beiden Oberflächen zueinander parallele Einschnitte sowohl in Längsrichtung als auch in Querrichtung aufweist, deren Tiefe etwa 1/4 bis 1/3 der Matratzendicke beträgt und wobei die Einschnitte in Längsrichtung der Matratze in gleichen Abständen voneinander verlaufen.The invention relates to a mattress made of a block of elastic flexible polyurethane foam, which has at least on one of the two surfaces mutually parallel incisions both in the longitudinal direction and in the transverse direction, the depth of which is about 1/4 to 1/3 of the mattress thickness and where the incisions in the longitudinal direction of the mattress run at equal distances from one another.

Eine solche Matratze ist aus der BE-A-682 014 bekannt. Dabei weisen jedoch auch die Einschnitte in Querrichtung zueinander jeweils einen gleichen Abstand auf, so daß damit die Matratze insgesamt überall die gleiche Härte und den gleichen Widerstand gegen auftretende Belastungen aufweist.Such a mattress is known from BE-A-682 014. However, the incisions in the transverse direction are each at the same distance from each other, so that the mattress has the same overall hardness and resistance to stresses.

Eine Matratze wird jedoch durch eine daraufliegende Person unterschiedlich stark belastet, wobei insbesondere im Schulterbereich und im Beckenbereich eine höhere Belastung auftritt, die jedoch durch die punktelastischen Eigenschaften einer Schaumstoffmatratze entsprechend ausgeglichen wird.A mattress, however, is loaded to different extents by a person lying on it, with a higher load occurring in particular in the shoulder area and in the pelvic area, but this is compensated accordingly by the point-elastic properties of a foam mattress.

Bei Schaumstoffmatratzen aus einem vollen Schaumstoffblock wird jedoch die Punktelastizität durch die Oberflächenspannung des Blockes etwas reduziert, d.h. eine solche Matratze macht zusätzlich beim Darauflegen einen etwas harten Eindruck.In the case of foam mattresses made from a full foam block, however, the point elasticity is somewhat reduced by the surface tension of the block, ie such a mattress also makes a somewhat hard impression when placed on it.

Der vorliegenden Erfindung liegt daher die Aufgabe zugrunde, eine Matratze zu schaffen, bei der mit äußerst einfachen Mitteln die Punktelastizität erhöht wird und eine gezielte Abstützfunktion erreichbar ist, ohne daß damit aber die charakteristischen Merkmale und das Federungsverhalten verhindert oder vermindert werden.The present invention is therefore based on the object of creating a mattress in which the point elasticity is increased with extremely simple means and a targeted support function can be achieved without, however, preventing or reducing the characteristic features and the suspension behavior.

Zur Lösung dieser Aufgabe ist erfindungsgemäß vorgesehen, daß die Einschnitte in Querrichtung in etwa dem ersten Drittel und die Einschnitte im letzten Drittel der Matratzenlänge einen geringeren Abstand voneinander aufweisen als die Einschnitte im mittleren Drittel.To achieve this object, it is provided according to the invention that the incisions in the transverse direction have a smaller distance from one another in approximately the first third and the incisions in the last third of the mattress length than the incisions in the middle third.

Durch diese Wahl der Abstände der Einschnitte läßt sich die Matratze in Zonen unterschiedlicher Härte unterteilen. So bringen nahe aneinanderliegende Einschnitte mehr Weichheit und lassen z.B. die Schulter weicher und tiefer einsinken, während breitere Einschnitte das Federungsverhalten des Materials verfestigen und somit mehr Abstützung bieten können.This choice of the spacing of the incisions allows the mattress to be divided into zones of different hardness. Incisions that are close together bring more softness and leave e.g. the shoulders sink in softer and deeper, while wider cuts strengthen the suspension behavior of the material and can therefore offer more support.

Zweckmäßigerweise weisen dabei die Einschnitte im mittleren Bereich der Matratzenlänge einen etwa doppelt so großen Abstand wie in den übrigen Bereichen auf.The incisions in the middle region of the mattress length are expediently approximately twice as large as in the other regions.

Ferner können zumindest die Einschnitte in Querrichtung der Matratze einen sich nach innen erweiternden, tropfenförmigen Querschnitt aufweisen.Furthermore, at least the incisions in the transverse direction of the mattress can have an inwardly widening, teardrop-shaped cross section.

Durch diese Gestaltung läßt sich eine höhere Flexibilität der Schaumsegmente auf der Längsachse des Matratzenkerns realisieren. Außerdem wird dadurch nochmals die Anpassungsfähigkeit des Materials an die Körperkontur gesteigert. Ferner bieten diese tropfenförmig verlaufenden Quereinschnitte eine geringere Gefahr des Einreißens des Materials an diesen kritischen Punkten. Ein weiterer Effekt liegt darin, daß durch diese tropfenförmigen Einschnitte Luftkanäle gebildet werden, wodurch die Luftdurchlässigkeit erhöht und die Durchlüftung verbessert wird.This design allows greater flexibility of the foam segments on the longitudinal axis of the mattress core realize. This also increases the material's adaptability to the body contour. Furthermore, these tear-shaped cross cuts offer a lower risk of the material tearing at these critical points. Another effect is that these teardrop-shaped incisions form air channels, which increases the air permeability and improves the ventilation.

Zweckmäßigerweise bestehen die Einschnitte in Längsrichtung aus vertikalen Schnitten ohne Materialentnahme oder können einen schmalen, rechteckigen Querschnitt aufweisen, der nur eine geringe Materialentnahme erfordert. Schließlich ist es noch zweckmäßig, wenn der jeweils erste Einschnitt parallel zu einer Matratzenkante einen größeren Abstand aufweist als der mittlere Abstand der übrigen Einschnitte voneinander beträgt.The incisions expediently consist of vertical cuts in the longitudinal direction without material removal or can have a narrow, rectangular cross section, which requires only a small amount of material removal. Finally, it is also expedient if the respective first incision is at a greater distance parallel to a mattress edge than the average distance of the other incisions from one another.

Damit und mit der Tatsache, daß die Matratze jeweils an den äußeren Kanten nur Einschnitte in einer Richtung, d.h. senkrecht zur jeweiligen Kante, aufweist, wird eine höhere Sitzstabilität erreicht.With this and with the fact that the mattress only cuts in one direction at the outer edges, ie perpendicular to the respective one Edge, a higher seating stability is achieved.

Anhand einer schematischen Zeichnung sind Aufbau und Funktionsweise eines Ausführungsbeispiels nach der Neuerung näher erläutert. Dabei zeigen:

The structure and mode of operation of an exemplary embodiment according to the innovation are explained in more detail using a schematic drawing. Show:

a view of a long side of the mattress,
Fig. 2
a view of an end face of the mattress, and
Fig. 3
a perspective view of the mattress as a whole.

Wie man insbesondere aus Fig. 1 und 3 ersieht, weist die Matratze 1 aus einem Block aus weichelastischem Polyurethan-Schaumstoff, üblicherweise in Form von herkömmlichem Polyether oder HR-Schaum, sowohl auf seiner Oberseite 2 als auch seiner Unterseite 3 quer zur Längsrichtung der Matratze 1 verlaufende Einschnitte 4, 5 und 6 auf, die einfach als senkrechte Schnitte oder aber nach dem dargestellten Ausführungsbeispiel mit einem nach unten erweiterten, tropfenförmigen Querschnitt ausgebildet sein können.As can be seen in particular from FIGS. 1 and 3, the mattress 1 has a block of soft elastic polyurethane foam, usually in the form of conventional polyether or HR foam, both on its top 2 and its bottom 3 transversely to the longitudinal direction of the mattress 1 extending incisions 4, 5 and 6, which can be simply formed as vertical cuts or, according to the illustrated embodiment, with a teardrop-shaped cross section widened downwards.

Entsprechend Fig. 2 und 3 sind auch in Längsrichtung der Matratze 1 parallel Einschnitte 7 bzw. 8 vorgesehen, die nach Fig. 2 einen schmalen, rechteckigen Querschnitt mit entsprechender Materialentnahme aufweisen, und nach Fig. 3 als einfache Einschnitte 8 ausgebildet sind.According to FIGS. 2 and 3, cuts 7 and 8 are also provided in parallel in the longitudinal direction of the mattress 1, which have a narrow, rectangular cross section according to FIG. 2 with corresponding material removal, and are designed as simple cuts 8 according to FIG. 3.

Die quer verlaufenden Einschnitte 4, 5 bzw. 6 und die längs verlaufenden Einschnitte 7 bzw. 8 erstrecken sich dabei über eine Höhe von etwa einem Viertel bis einem Drittel der gesamten Dicke der Matratze 1.The transverse incisions 4, 5 and 6 and the longitudinal incisions 7 and 8 extend over a height of approximately a quarter to a third of the total thickness of the mattress 1.

Wie man insbesondere aus Fig. 3 erkennt, werden somit durch die sich senkrecht schneidenden Einschnitte 4, 5, 6 sowie 8 diskrete Oberflächenabschnitte 9 quadratischer oder rechteckiger Fläche freigeschnitten, die sich bei Belastung gesondert und unabhängig von den umgebenden Flächenelementen absenken bzw. elastisch verformen können.As can be seen in particular from FIG. 3, the vertically intersecting incisions 4, 5, 6 and 8 discrete surface sections 9 of a square or rectangular surface are thus cut free, which can separate or deform elastically under load independently of the surrounding surface elements.

Durch diese freigeschnittenen Einzelbereiche 9 wird also einmal die Oberflächenspannung des Schaumstoffblockes 1 reduziert und zum anderen die ansich einem Schaumstoff schon innewohnende Punktelastizität noch zusätzlich erhöht, da sich besonders belastete Oberflächenabschnitte 9 leicher und stärker absenken können, während die übrigen Abschnitte ihre Gesamtstützkraft aufrechterhalten.By means of these cut-out individual areas 9, the surface tension of the foam block 1 is reduced on the one hand and, on the other hand, the point elasticity inherent in a foam is additionally increased, since particularly stressed surface sections 9 can lower more easily and more strongly, while the remaining sections maintain their overall supporting force.

Zur weiteren, gezielten Anpassung der Härte der Matratze an auftretende Belastungen können insbesondere die querliegenden Einschnitte 4, 5, 6 unterschiedliche Abstände voneinander aufweisen. Wie man insbesondere aus Fig. 1 ersieht, sind die Abstände der Einschnitte 4 im ersten Drittel der Matratze 1 und die Abstände der Einschnitte 6 im dritten Drittel geringer als die Abstände der Einschnitte 5 im mittleren Bereich. Damit wirkt die Matratze z.B. im Schulterbereich weicher, obwohl der Matratzenblock insgesamt in seinem Federungsverhalten unverändert bleibt und die dem Material eigene Rückstellenergie beibehält.For further, targeted adjustment of the hardness of the mattress to occurring loads, the transverse incisions 4, 5, 6 in particular can have different distances from one another. As can be seen in particular from FIG. 1, the distances between the incisions 4 in the first third of the mattress 1 and the distances between the incisions 6 in the third third are smaller than the distances between the incisions 5 in the central region. So the mattress works e.g. softer in the shoulder area, although the overall suspension behavior of the mattress block remains unchanged and the material's own restoring energy is retained.

Wie man ferner aus der Aufsicht nach Fig. 3 ersieht, weisen die jeweiligen Kantenbereiche 10, 11, 12 und 13 über einen breiteren Bereich nur Einschnitte auf, die senkrecht zur jeweiligen Kante verlaufen. Dadurch wird eine höhere Sitzstabilität auf den Kanten einer solchen, mit Einschnitten versehenen Matratze erreicht.3, the respective edge areas 10, 11, 12 and 13 have only incisions over a wider area that are perpendicular to the respective edge. As a result, a higher seating stability is achieved on the edges of such a mattress provided with incisions.

Insgesamt ergibt sich also eine Matratze aus einem einstückigen, homogenen Material, bei der mit einfachen, sich kreuzenden Einschnitten gezielt Bereiche größerer Weichheit geschaffen werden können, ohne daß darunter die Gesamtelastizität leidet. Ein Ausschneiden und aufwendiges Verkleben von Matratzenbereichen aus Schaumstoffteilen unterschiedlicher Härte kann damit entfallen.Overall, this results in a mattress made of a one-piece, homogeneous material in which areas of greater softness can be created in a targeted manner with simple, intersecting incisions, without the overall elasticity suffering as a result. A cutting out and complex gluing of mattress areas from foam parts of different hardness can thus be omitted.
