Abstract

A flat core (1) made of elastic material, for example plastic foam, is provided with continuous holes (2). Support beads (3) are placed loosely in these openings (2) and the latter are closed by elastic outer layers (4) which are bonded on on both sides. Thus a mattress is obtained in a simple manner which has a relatively large number of firm support bodies located in a central zone and soft elastic outer layers. On the outside, the mattress corresponds to a customary mattress and can correspondingly be used as any customary mattress. However, with the inserted support bodies, it causes an uneven, punctiform support of a person lying on the mattress with locally increased pressure, which brings about a desired massage effect and, additionally, due to a piston effect favours forced ventilation towards the top. <IMAGE>

Description

Die vorliegende Erfindung betrifft eine Matratze gemäss Oberbegriff des Anspruchs 1. Eine derartige Matratze ist aus der GB-A 2 073 015 bekannt, wobei zylindrische Stützkörper in zylindrische Durchbrechungen der Mittelzone der Matratze fest eingesetzt sind. Mit diesem Aufbau wird eine örtliche Anpassung der Elastizität der Matratze aber kein Massageeffekte oder dergleichen physiologische Wirkung angestrebt, und die Herstellung ist durch das Einbauen der Stützkörper umständlich und aufwendig.The present invention relates to a mattress according to the preamble of claim 1. Such a mattress is known from GB-A 2 073 015, cylindrical support bodies being firmly inserted into cylindrical openings in the central zone of the mattress. With this structure, a local adaptation of the elasticity of the mattress is sought but no massage effects or the like physiological effect, and the manufacture is cumbersome and complex due to the installation of the support body.

Aus der GB-A 2 084 010 ist eine Matratze bekannt in die flache Permanentmagnete mit einseitig konvexer Oberfläche eingesetzt sind. Diese Magnete wirken ausschliesslich durch ihr Magnetfeld, denn sie sind zu flach für eine wirksame örtliche Stützung des Körpers. Im übrigen wäre eine eventuelle derartige Wirkung nur einseitig, d.h. unsymmetrisch, so dass die Matratze nicht in beliebiger Lage benützt werden kann.From GB-A 2 084 010 a mattress is known in which flat permanent magnets with a convex surface on one side are inserted. These magnets work exclusively through their magnetic field, because they are too flat for effective local support of the body. Otherwise, any such effect would only be one-sided, i.e. asymmetrical so that the mattress cannot be used in any position.

Es sind auch Matratzen bekannt, welche an einer flachen Unterlage angeformte oder befestigte, vorstehende, halbkugelförmige oder pyramidenförmige Körper aufweisen, welche der direkten Abstützung einer sitzenden oder liegenden Person dienen (DE-A 3 524 236 und 3 525 960). Diese Matratzen mit aussen angebrachten Erhebungen und Vertiefungen werden als störend empfunden und sind bei längerem Gebrauch physiologisch unbefriedigend.Mattresses are also known which have protruding, hemispherical or pyramid-shaped bodies which are molded onto or attached to a flat base and which serve to directly support a person who is sitting or lying down (DE-A 3 524 236 and 3 525 960). These mattresses with elevations and depressions attached to the outside are perceived as disturbing and are physiologically unsatisfactory with prolonged use.

Ziel vorliegender Erfindung ist es nun, eine Matratze zu schaffen, welche einfach herstellbar ist, äußerlich den herkömmlichen Matratzenformen entspricht und auch in jeder Beziehung wie solche verwendet und kombiniert werden kann, und welche den angestrebten physiologischen Effekt ohne negative Nebenwirkungen in besonders vorteilhafter Weise bewirkt. Dieses Ziel wird gemäss Kennzeichen des Anspruchs 1 erreicht. Gegenstand der Erfindung ist auch ein besonders einfaches, leicht mechanisierbares Herstellungsverfahren für die Matratze, welches im Anspruch 8 angegeben wird.The aim of the present invention is now to provide a mattress which is easy to manufacture, corresponds externally to the conventional mattress shapes and can also be used and combined in any way, and which has the desired physiological effect without negative side effects in a particularly advantageous manner. This goal is achieved according to the characterizing part of claim 1. The invention also relates to a particularly simple, easily mechanizable manufacturing method for the mattress, which is specified in claim 8.

Die Erfindung wird nun anhand eines in der Zeichnung dargestellten Ausführungsbeispiels näher erläutert. In der Zeichnung zeigen:

  • Fig. 1 eine Teildraufsicht auf einen käfigartigen Matratzenkern,
  • Fig. 2 eine räumliche Teilansicht dieses Matratzenkerns mit eingelegten Stützkugeln,
  • Fig. 3 einen schematischen Teilschnitt durch die mit elastischen Aussenschichten versehene Matratze und
  • Fig. 4 einen entsprechenden schematischen Teilschnitt durch die fertige Matr- :ze.
The invention will now be explained in more detail with reference to an embodiment shown in the drawing. The drawing shows:
  • 1 is a partial plan view of a cage-like mattress core,
  • 2 is a partial spatial view of this mattress core with inserted support balls,
  • Fig. 3 is a schematic partial section through the mattress provided with elastic outer layers and
  • 4 shows a corresponding schematic partial section through the finished mattress:

Zur Herstellung der dargesocallten Matratze wird ein Matratzenkern 1 mit durchgehenden Löchern 2 vorbereitet. In diesen käfigartigen Kern 1 werden sodann gemäss Fig. 2 Kugeln 3 in jede Durchbrechung eingelegt, was vorzugsweise vollautomatisch, maschinell geschehen kann. Sodann wird der Kern beidseitig mit elastischen Aussenschichten 4 verklebt. Diese Aussenschichten sind in Fig. 3 zweiteilig dargestellt, sie können aber auch einteilig ausgeführt sein. Gemäss Fig. 4 können dann noch weitere Auflagen, beispielsweise pflanzliche oder tierische Naturfasern oder synthetische Vliese 5 aufgelegt werden, worauf der Einfassungsstoff angebracht wird. Es entsteht damit eine Matratze äusserlich üblicher Form. Der Kern 1 und die Aussenschichten 4 können aus Kaltschaum, Latexschaumgummi, einem Federkern, pflanzlichen oder tierischen Fasern oder Kombinationen derselben bestehen. Vorzugsweise wird für den Kern 1 ein Schaum verwendet. Die eingelegten Stützkörper erfüllen die Funktion der Verstärkung der Mittelzone. Die Aussenschichten bestehen vorzugsweise aus Schaumstoff weicherer Schäumung oder Latexschaumgummi und wirken somit als anschmiegsame, anatomisch richtige Polster.A mattress core 1 with through holes 2 is prepared for the manufacture of the mattress. In this cage-like core 1, balls 3 are then inserted into each opening according to FIG. 2, which can preferably be done fully automatically, mechanically. The core is then glued on both sides with elastic outer layers 4. These outer layers are shown in two parts in FIG. 3, but they can also be made in one part. According to FIG. 4, further pads, for example vegetable or animal natural fibers or synthetic nonwovens 5, can then be placed on which the edging material is applied. The result is a mattress of an outwardly customary shape. The core 1 and the outer layers 4 can consist of cold foam, latex foam rubber, a spring core, vegetable or animal fibers or combinations thereof. A foam is preferably used for the core 1. The inserted support bodies fulfill the function of reinforcing the central zone. The outer layers are preferably made of foam softer foam or latex foam and thus act as a cuddly, anatomically correct cushion.

Die Stützkörper 3 können aus Hartschaum, Gummi, Holz, Kunststoff, Styropor, Metall oder dergleichen verglichen mit den übrigen Teilen festem Material bestehen. Vorzugsweise weisen auch die Stützkörper eine gewisse Elastizität, wenn auch eine wesentlich geringere Zusammendrückbarkeit als die anderen Bestandteile, auf. Sie können vorzugsweise die dargestellte Kugelform aufweisen, doch sind verschiedenste andere Formen mit konvexen Stützflächen denkbar, beispielsweise ellipsoidförmige Stützkörper, zylindrische Stützkörper mit bombierten Endflächen, walzenförmige Stützkörper mit konvexen Noppen oder Stützkörper. Zur Einsparung von Material und Gewicht können sie vorzugsweise hohl ausgeführt sein, doch können sie auch mit bestimmten Materialien, beispielsweise Wasser oder Luft, gefüllt sein. Die Stützkugeln 3 weisen vorzugsweise einen Durchmesser von 25-50 mm und die Aussenschichten 4 vorzugsweise gleiche Dicke von ungefähr 15-40 mm auf. Bei diesen Abmessungen ergeben sich optimale Bedingungen zur Abstützung einer Person mit stellenweise erhöhtem Druck, wobei für leichtere Personen kleinere oder weichere, für schwerere Personen grössere oder härtere Stützkörper verwendet werden. Zudem können die Aussenschichten 4 für höheres Körpergewicht fester ausgeführt werden. Dank der Einbettung der Stützkörper zwischen zwei elastische Aussenschichten 4 ergibt sich jeweils eine progressive Druckerhöhung, d.h. je stärker die Aussenschichten stellenweise belastet werden, umso stärker dringen die Kugeln in sie ein, umso grösser wird die wirksame Stützfläche und umso grösser wird die lokale Belastung. Die in den durchgehenden Ausnehmungen 2 befindlichen Stützkörper 3 können als Kolben wirken, welche die Luft nach oben verdrängen und damit eine gute Durchlüftung und Sauerstoffzufuhr zur liegenden Person bewirken. Anstelle eines Käfigs für die Stützkörper, welcher aus einem Kern 1 mit durchgehenden Löchern und beidseitig aufgeklebten Deckschichten besteht, könnten zwei schalenartige Hälften mit nicht durchgehenden Ausnehmungen vorgesehen sein. Zur Herstellung könnten nun die Stützkugeln 3 in die Ausnehmungen der einen Schale eingelegt und dann die gegengleiche Schale aufgelegt und verklebt werden. Es entsteht dabei eine entsprechende Struktur mit in Ausnehmungen lose gehaltenen Stützkörpern und beidseitig ausserhalb derselben liegenden Wandteilen, die elastische Aussenschichten bilden.The support body 3 can consist of hard foam, rubber, wood, plastic, polystyrene, metal or the like compared to the other parts of solid material. The support bodies preferably also have a certain elasticity, even if they are much less compressible than the other components. They can preferably have the spherical shape shown, but a wide variety of other shapes with convex support surfaces are conceivable, for example ellipsoidal support bodies, cylindrical support bodies with convex end faces, roller-shaped support bodies with convex knobs or support bodies. To save material and weight, they can preferably be hollow, but they can also be filled with certain materials, for example water or air. The support balls 3 preferably have a diameter of 25-50 mm and the outer layers 4 preferably have the same thickness of approximately 15-40 mm. These dimensions result in optimal conditions for supporting a person with increased pressure in places, smaller or softer support bodies being used for lighter persons and larger or harder support bodies for heavier persons. In addition, the outer layers 4 can be made firmer for higher body weight. Thanks to the embedding of the support body between two elastic outer layers 4, there is a progressive pressure increase, i.e. The more the outer layers are loaded in places, the more the balls penetrate them, the larger the effective support surface and the greater the local load. The support bodies 3 located in the continuous recesses 2 can act as pistons, which displace the air upwards and thus bring about good ventilation and oxygen supply to the person lying down. Instead of a cage for the support body, which consists of a core 1 with continuous holes and cover layers glued on both sides, two shell-like halves with non-continuous recesses could be provided. For the production, the support balls 3 could now be inserted into the recesses of the one shell and the opposite shell then placed and glued. The result is a corresponding structure with supporting bodies held loosely in recesses and wall parts lying on both sides outside the same, which form elastic outer layers.
