Each core includes a breathable non-woven fabric. The coefficient of friction of the fabric is smaller than that of the core material. Furthermore, the cores have recesses joined together to define circular passages. Ventilation holes are formed on the base. An independent claim is also included for a method for cleaning a mattress.

Description

Die vorliegende Erfindung betrifft eine Matratze mit einem Matratzenrahmen, wobei in dem Innenraum des Rahmens Kernelemente vorgesehen sind, die in den Rahmeninnenraum von der Matratzenlängsseite her einsetzbar sind und sich quer dazu erstrecken.The present invention relates to a mattress with a mattress frame, wherein in the interior of the frame core elements are provided which are insertable into the frame interior of the mattress longitudinal side and extend transversely thereto.

Modulartig aufgebaute Matratzen dieser Art mit auswechselbaren Kernelementen sind bekannt. Ihr Vorteil besteht gegenüber herkömmlichen Latex- oder Federkernmatratzen darin, dass durch die Verwendung von Kernelementen unterschiedlicher Härten verschieden harte Stützzonen realisiert werden können, die an die individuellen Bedürfnisse des Benutzers angepaßt sind. Bei bekannten Matratzen, die von der Firma Prosleep vertrieben werden, sind insgesamt vierzehn Kernelemente (Trimont-Module) vorgesehen, die einen sich von einer Basisfläche nach oben hin verjüngenden, gestuften Querschnitt besitzen und im Wechsel mit der Basis unten- und obenliegend in den Matratzenrahmen eingesetzt sind, wobei zwischen den Kernmodulen horizontal verlaufende Belüftungskanäle gebildet werden.Modular mattresses of this type with interchangeable core elements are known. Their advantage over conventional latex or spring mattresses is that the use of core elements of different hardnesses different hard support zones can be realized, which are adapted to the individual needs of the user. In known mattresses sold by the company Prosleep, a total of fourteen core elements (trimont modules) are provided which have a stepped cross-section tapering from a base surface and alternating with the base at the top and bottom of the mattress frame are used, wherein between the core modules horizontally extending ventilation channels are formed.

An diesem Matratzensystem wird als nachteilig angesehen, dass weder die Matratze als Ganzes noch die einzelnen Elemente waschbar sind, wodurch die Hygiene, insbesondere z.B. für Allergiker oder für den Einsatz in Krankenhäusern nicht zufriedenstellend ist.In this mattress system is considered disadvantageous that neither the mattress as a whole nor the individual elements are washable, whereby the hygiene, in particular, e.g. is not satisfactory for allergy sufferers or for use in hospitals.

Vor diesem Hintergrund liegt der vorliegenden Erfindung die Aufgabe zugrunde, eine Matratze der eingangs genannten Art anzugeben, die waschbar ist sowie ein Verfahren zur Reinigung von Matratzen bereitzustellen.Against this background, the present invention seeks to provide a mattress of the type mentioned, which is washable and to provide a method for cleaning mattresses.

Diese Aufgabe ist erfindungsgemäß dadurch gelöst, dass die Kernelemente blockförmig ausgebildet sind und mit einem atmungsaktiven Material, insbesondere Vliesstoff, bezogen sind, das einen geringeren Reibungskoeffizienten besitzt als das Material der Kernelemente.This object is inventively achieved in that the core elements are block-shaped and are covered with a breathable material, in particular nonwoven fabric, which has a lower coefficient of friction than the material of the core elements.

Die Ausgestaltung der Kernelemente mit einem Überzug bietet den Vorteil, dass die Kernelemente gewaschen werden können. Bei abnehmbaren Überzügen können auch die Überzüge alleine gewaschen werden. Mithin ist die erfindungsgemäße Matratze sehr hygienisch und insbesondere für den Einsatz in Krankenhäusern gut geeignet.The design of the core elements with a coating offers the advantage that the core elements can be washed. With removable coatings, the coatings can be washed alone. Thus, the mattress according to the invention is very hygienic and particularly well suited for use in hospitals.

Beispielsweise können die Überzüge aus einem Vliesstoff oder aus atmungsaktiven Distanzgestricken bestehen, welche einen geringen Reibungskoeffizienten besitzen und zudem die Luftzirkulation optimieren. Außerdem wird dadurch das Auswechseln der einzelnen Kernelemente, bei welchen es sich in der Regel um Schaumstoffblöcke aus einem elastischen Material handelt, erleichtert.For example, the coatings may consist of a nonwoven fabric or breathable spacer knits, which have a low coefficient of friction and also optimize air circulation. In addition, this is the replacement of the individual core elements, in which As a rule, these are foam blocks made of an elastic material.

Bei einer Ausführungsform der Erfindung ist vorgesehen, jeweils eine der Breite der Matratze entsprechende Länge, eine der Höhe des Rahmeninnenraums entsprechende Höhe und eine Breite von 5 bis 10 cm, insbesondere von 7 bis 8 cm besitzen. Dadurch, dass bei der erfindungsgemäßen Matratze die Kernelemente blockförmig ausgebildet sind, wird die Möglichkeit geschaffen, diskrete Stützzonen mit einer vorgegebenen, definierten Härte zu schaffen. Bei den herkömmlichen Matratzen ist dies nicht möglich, da sich die Kernelemente teilweise überlagern. Weiterhin ist die Breite der Kernelemente vergleichsweise gering gewählt, so dass die erfindungsgemäße Matratze eine hohe Anzahl von Stützzonen besitzt, in welchen die Härte individuell eingestellt werden kann, indem ein Kernelement mit einer gewünschten Härte oder Festigkeit eingesetzt wird. Vorzugsweise können die Kernelemente aus zehn unterschiedlichen Qualitäten ausgewählt werden. Um dabei die Anzahl unterschiedlicher Kernelemente niedrig zu halten, ist gemäß einer bevorzugten Ausführungsform vorgesehen, dass die Kernelemente alle die gleiche Breite besitzen, so dass das System tatsächlich nur so viele unterschiedliche Kernelemente benötigt, wie Härtegrade realisiert werden sollen.In one embodiment of the invention is provided, in each case one of the width of the mattress corresponding length, the height of the frame interior corresponding height and a width of 5 to 10 cm, in particular from 7 to 8 cm have. The fact that in the mattress according to the invention, the core elements are block-shaped, the possibility is created to create discrete support zones with a predetermined, defined hardness. In conventional mattresses, this is not possible because the core elements partially overlap. Furthermore, the width of the core elements is chosen to be comparatively small, so that the mattress according to the invention has a high number of support zones in which the hardness can be adjusted individually by using a core element with a desired hardness or strength. Preferably, the core elements may be selected from ten different qualities. In order to keep the number of different core elements low, it is provided according to a preferred embodiment that the core elements all have the same width, so that the system actually only requires as many different core elements as hardness levels are to be realized.

Gemäß einer bevorzugten Ausführungsform ist vorgesehen, dass die Kernelemente an ihrer Oberseite insbesondere an den Übergangsbereichen zu ihren Seitenwänden abgerundet ausgebildet sind. Hierdurch soll erreicht werden, dass an den Übergängen zwischen den Kernelementen unterschiedlicher Festigkeit keine Schärkräfte auftreten und ein sanfter Übergang zwischen den Kernelementen möglich ist.According to a preferred embodiment, it is provided that the core elements on their upper side in particular The transition areas are rounded to their side walls. This is to ensure that at the transitions between the core elements of different strength no sharpening forces occur and a smooth transition between the core elements is possible.

In weiterer Ausgestaltung der Erfindung können die Kernelemente an ihren Längsseiten Aussparungen aufweisen, die sich über die gesamte Höhe der Kernelemente erstrecken. Dabei können die Aussparungen von zwei benachbarten Kernelementen einander paarweise gegenüberliegen, so dass sie gemeinsam eine Durchgangsöffnung bilden. Beispielsweise ist es möglich, die Aussparungen halbrund auszubilden, so dass sich paarweise gegenüberliegende Aussparungen zu einer kreisförmigen Durchgangsöffnung ergänzen, die dann zweckmäßigerweise einen Radius von 0, 5 bis 1 cm hat.In a further embodiment of the invention, the core elements may have recesses on their longitudinal sides, which extend over the entire height of the core elements. In this case, the recesses of two adjacent core elements facing each other in pairs, so that they together form a passage opening. For example, it is possible to form the recesses semicircular, so that complement each other in pairs opposite recesses to a circular passage opening, which then expediently has a radius of 0.5 to 1 cm.

Diese Durchgangsöffnungen bilden ein Belüftungssystem der erfindungsgemäßen Matratze. Wenn sich eine auf der Matratze liegende Person bewegt, ergibt sich durch die elastischen/viscoelastischen Verformungen und Rückverformungen sogar ein leichter Pumpeffekt, durch welchen die erfindungsgemäße Matratze besser belüftet wird als herkömmliche Matratzen.These passage openings form a ventilation system of the mattress according to the invention. When a person lying on the mattress moves, the elastic / viscoelastic deformations and rebounding even result in a slight pumping effect, by which the mattress according to the invention is better ventilated than conventional mattresses.

In der Zeichnung ist eine erfindungsgemäße Matratze 1 dargestellt, welche die üblichen Abmessungen mit eine Länge von 2 m, einer Breite von 1 m und einer Höhe von 25 cm besitzt. Die Matratze besitzt einen elastischen Matratzenrahmen 1 aus Schaumstoff. Dieser wird von einem flächigen Bodenelement 2 und einem ebenfalls flächigen Oberteil 3 gebildet, die an den Querseiten der Matratze durch blockartige Kopf- und Fußelemente 4, 5 miteinander verbunden, beispielsweise verklebt sind und beabstandet gehalten werden.In the drawing, a mattress 1 according to the invention is shown, which has the usual dimensions with a length of 2 m, a width of 1 m and a height of 25 cm. The mattress has an elastic mattress frame 1 made of foam. This is formed by a flat bottom element 2 and a likewise flat upper part 3, which are connected to each other at the transverse sides of the mattress by block-like head and foot elements 4, 5, for example glued and are kept at a distance.

In dem Rahmeninnenraum sind insgesamt 26 blockförmig ausgebildete Kernelemente 6 aus Schaumstoff vorgesehen, die in den Matratzenrahmen 1 von dessen Längsseite her eingesetzt sind und sich parallel zu den Matratzenquerseiten erstrecken. Die Kernelemente 6 besitzen eine der Höhe des Rahmeninnenraums entsprechende Höhe von hier etwa 14 cm, eine der Matratzenbreite entsprechenden Länge von 1 m und eine Breite von etwa 7 cm. Die Kernelemente 6 sind in zehn unterschiedliche Härte- bzw. Festigkeitsqualitäten erhältlich, so dass die Matratzenhärte bzw. -festigkeit in der Matratzenlängsrichtung individuell an die Bedürfnisse eines Benutzers eingestellt werden kann. Wie insbesondere die Figur 2 gut erkennen läßt, sind die Kernelemente 6 dabei an ihren Oberseiten 6a und insbesondere in ihren Übergangsbereichen zu den Längsseitenwänden 6b abgerundet ausgebildet, damit an den Übergängen zwischen verschiedenen Kernelementen 6 mit unterschiedlichen Festigkeiten keine oder nur geringe Scherkräfte auftreten und ein sanfter Übergang zwischen den Kernelementen 6 möglich ist. Der Radius der Rundung sollte mindestens 3,5 cm betragen.In the frame interior a total of 26 block-shaped core elements 6 are provided made of foam, the are inserted into the mattress frame 1 from the longitudinal side and extend parallel to the mattress transverse sides. The core elements 6 have a height of the frame interior corresponding height of about 14 cm here, a mattress width corresponding length of 1 m and a width of about 7 cm. The core elements 6 are available in ten different hardness or strength qualities, so that the mattress hardness or strength in the mattress longitudinal direction can be adjusted individually to the needs of a user. As can be clearly seen in particular in FIG. 2, the core elements 6 are rounded on their upper sides 6a and in particular in their transitional areas to the longitudinal side walls 6b, so that no or only shearing forces occur at the transitions between different core elements 6 with different strengths and a gentler one Transition between the core elements 6 is possible. The radius of the rounding should be at least 3.5 cm.

Wie die Draufsicht aus Figur 3 weiterhin zeigt, sind die Längsseitenwände 6b der Kernelemente 6 mit gestanzten Aussparungen 7 versehen, welche sich über die gesamte Höhe der Kernelemente 6 erstrecken. Die Aussparungen 7 sind halbrund ausgebildet, wobei die Aussparungen 7 von nebeneinanderliegenden Kernelementen 6 einander paarweise gegenüberliegen und sich zu einer kreisförmigen Durchgangsöffnung 8 mit einem Radius von 0,5 bis 1 cm ergänzen. Diese Durchgangsöffnungen 8 stellen das vertikale Belüftungssystem der Matratze dar, in welchem Luft zwischen der Matratzenoberseite und der Matratzenunterseite zirkulieren kann. Es hat sich gezeigt, dass durch die Bewegungen einer auf der Matratze liegenden Person und den damit verbundenen ständigen Verformungen und Rückverformungen ein Pumpeffekt in den Durchgangsbohrungen 8 auftrifft.As the plan view of Figure 3 further shows, the longitudinal side walls 6b of the core elements 6 are provided with punched recesses 7, which extend over the entire height of the core elements 6. The recesses 7 are formed semicircular, the recesses 7 of adjacent core elements 6 facing each other in pairs and complement each other to a circular passage opening 8 with a radius of 0.5 to 1 cm. These passage openings 8 provide the vertical ventilation system the mattress, in which air can circulate between the mattress top and the mattress base. It has been shown that a pumping effect impinges in the through-holes 8 by the movements of a person lying on the mattress and the associated permanent deformations and re-deformations.

In der Zeichnung nicht erkennbar ist, dass die Kernelemente 6 mit einem atmungsaktiven Material, insbesondere ein Vliesstoff bezogen sind, welcher einen vergleichsweise geringen Reibungskoeffizienten besitzt, so dass einzelne Kernelemente 6 aus der in Figur 1 gezeigten Matratze mit geringem Aufwand entnommen und anschließend ein neues Kernelement 6 eingeschoben werden kann.It can not be seen in the drawing that the core elements 6 are covered with a breathable material, in particular a nonwoven, which has a comparatively low coefficient of friction, so that individual core elements 6 are removed from the mattress shown in FIG. 1 with little effort and subsequently a new core element 6 can be inserted.

Das flächige Bodenelement des Matratzenrahmens 1 besitzt hier eine Höhe von etwa 4 cm und besteht aus einem festeren Schaumstoffmaterial, das der Matratze von unten her Halt geben und sie stabilisieren soll. Nicht gezeigt ist, dass über das gesamte Bodenelement 2 verteilt Lüftungslöcher mit einem Durchmesser von beispielsweise 0,5 bis 1 cm vorgesehen sind, um die Luftzirkulation in der Matratze zu erhöhen.The flat bottom element of the mattress frame 1 here has a height of about 4 cm and consists of a firmer foam material, which should give the mattress from below hold and stabilize it. Not shown is provided over the entire floor element 2 distributed ventilation holes with a diameter of, for example, 0.5 to 1 cm, to increase the air circulation in the mattress.

Das Matratzenoberteil 3 ist zweischichtig ausgebildet und besitzt eine obere erste Schicht 3a aus einem viskoelastischen Schaumstoffmaterial und eine darunterliegende Schicht 3b aus einem atmungsaktiven Schaumstoff. Wie insbesondere die Figur 4 zeigt, ist die erste Schicht 3a als Noppenschaumschicht ausgebildet, wobei sie eine Höhe von etwa 4 cm besitzt. Solche Noppenschaummaterialien oder auch Pyramidenschaummaterialien mit einzelnen, sich nach oben hin kegelförmig oder pyramidenförmig verjüngenden Noppen 9 sind an sich bekannt und werden insbesondere auch zu Schallisolationszwecken eingesetzt. In der erfindungsgemäßen Matratze bewirken die einzelnen Noppen 9 eine Oberflächenvergrößerung und zudem noch einen Massageeffekt, welcher die Mikrozirkulation in dem Gewebe einer auf der Matratze liegenden Person unterstützen und beleben soll.The mattress top 3 is formed in two layers and has an upper first layer 3a of a viscoelastic foam material and an underlying layer 3b of a breathable foam. As particularly shown in FIG. 4, the first layer 3a is as Noppenschaumschicht formed, wherein it has a height of about 4 cm. Such nub foam materials or pyramidal foam materials with individual upwardly conically or pyramidally tapering nubs 9 are known per se and are used in particular for sound insulation purposes. In the mattress according to the invention, the individual knobs 9 cause an increase in surface area and, moreover, a massaging effect which is intended to support and enliven the microcirculation in the tissue of a person lying on the mattress.

Die unter der Noppenschaumschicht 1 liegende zweite Schicht 3b hat im wesentlichen die Funktion, Feuchtigkeit vom Körper weg zu transportieren.The second layer 3b underlying the nub foam layer 1 essentially has the function of transporting moisture away from the body.

Nicht dargestellt ist, dass die Matratzenanordnung mit einem Überzug versehen ist. Dieser Überzug kann aus Materialien wie beispielsweise Mikrocare oder Lyocell bestehen und gegebenenfalls mit einem atmungsaktiven Distanzgestrick ausgestattet sein, um die Luftzirkulation und somit das Schlafklima weiter zu verbessern.Not shown is that the mattress assembly is provided with a coating. This coating can be made of materials such as microcare or lyocell and optionally equipped with a breathable spacer fabric to further improve the air circulation and thus the sleeping environment.
