Definitions
- the invention relates to a mattress core made of foam, plastic or latex, which has a number transverse to its longitudinal axis extending cavities, wherein in each of the cavities a coil spring is arranged.
- Foam mattress cores have been known for a long time.
- the structure of these mattress cores usually consists of flat or profiled flat elements of foams of the same or different hardness.
- Such mattress cores are known from the patents AT 361 165 and AT 370 603. These mattress cores also have no good ventilation, as due to the function-related small cavity cross-sections too small air volume in the mattress is present. For this reason, the very costly slatted frames are still necessary for the removal of moisture. Furthermore, no compact mattress with a very good ventilation can be produced by the multilayer structure without bonding.
- mattresses which have cavities extending from one side surface to the other side surface of the mattress, which cavities are provided for receiving random packings of very different structures. Both solid and hollow packing can be provided.
- the present invention is therefore based on the object to provide a mattress core, which has a large volume of air sufficient volume for optimum lateral ventilation and ensures lateral moisture removal without the use of a complex slatted frame.

Description
Die Erfindung betrifft einen Matratzenkern aus Schaumstoff, Kunststoff oder Latex, welcher eine Reihe quer zu seiner Längsachse verlaufende Hohlräume aufweist, wobei in jedem der Hohlräume eine Spiralfeder angeordnet ist.The invention relates to a mattress core made of foam, plastic or latex, which has a number transverse to its longitudinal axis extending cavities, wherein in each of the cavities a coil spring is arranged.
Matratzenkerne aus Schaumstoff sind seit längeren bekannt.Foam mattress cores have been known for a long time.
Der Aufbau dieser Matratzenkerne besteht zumeist aus ebenen oder profilierten flächigen Elementen aus Schaumstoffen gleicher oder unterschiedlicher Härte. Mit diesen Kombinationen wurden die Liegeeigenschaften immer wieder verbessert, wobei aber eine ausreichende Durchlüftung und Feuchtigkeitsabfuhr nicht erreicht werden konnte, da unter Belastung durch das Einsinken des Benutzers, die vorgesehen Kanäle derart deformiert werden, dass eine gute Durchlüftung unterbleibt.The structure of these mattress cores usually consists of flat or profiled flat elements of foams of the same or different hardness. With these combinations, the lying properties were repeatedly improved, but a sufficient ventilation and moisture removal could not be achieved because under pressure from the sinking of the user, the channels provided are deformed so that a good ventilation is omitted.
Derartige Matratzenkerne sind aus den Patentschriften AT 361 165 und AT 370 603 bekannt. Diese Matratzenkerne weisen auch keine gute Durchlüftung auf, da durch die funktionsbedingten kleinen Hohlraumquerschnitte ein zu geringes Luftvolumen in der Matratze vorhanden ist. Aus diesem Grund sind für die Feuchtigkeitsabfuhr noch immer die sehr aufwendigen Lattenroste notwendig. Weiters ist durch den mehrlagigen Aufbau ohne Verklebung keine Kompaktmatratze mit einer sehr guten Durchlüftung herstellbar.Such mattress cores are known from the patents AT 361 165 and AT 370 603. These mattress cores also have no good ventilation, as due to the function-related small cavity cross-sections too small air volume in the mattress is present. For this reason, the very costly slatted frames are still necessary for the removal of moisture. Furthermore, no compact mattress with a very good ventilation can be produced by the multilayer structure without bonding.
Aus der US 6 061 856 A sind Matratzen bekannt, welche von der einen Seitenfläche zur anderen Seitenfläche der Matratze verlaufende Hohlräume aufweisen, welche zur Aufnahme von Füllkörpern, verschiedenster Struktur vorgesehen sind. Dabei können sowohl massive als auch hohle Füllkörper vorgesehen sein.From US Pat. No. 6,061,856 A, mattresses are known which have cavities extending from one side surface to the other side surface of the mattress, which cavities are provided for receiving random packings of very different structures. Both solid and hollow packing can be provided.
Es ist weiters bekannt, dass wegen der schlechten Luftzirkulation im Matratzenkern ein feuchtes Klima entsteht, welches ein guter Nährboden für Ungeziefer, Pilze und Bakterien ist. Diese eingenisteten Kulturen sind im allgemeinen für Allergien und für die Entstehung von unangenehmen Gerüchen verantwortlich.It is also known that due to the poor air circulation in the mattress core creates a humid climate, which is a good breeding ground for vermin, fungi and bacteria. These nested cultures are generally responsible for allergies and the development of unpleasant odors.
Der vorliegenden Erfindung liegt daher die Aufgabe zu Grunde einen Matratzenkern zu schaffen, der durch große Hohlräume ein ausreichendes Luftvolumen für eine optimale seitliche Durchlüftung aufweist und eine seitliche Feuchtigkeitsabfuhr ohne die Verwendung eines aufwendigen Lattenrostes gewährleistet.The present invention is therefore based on the object to provide a mattress core, which has a large volume of air sufficient volume for optimum lateral ventilation and ensures lateral moisture removal without the use of a complex slatted frame.
Gemäß der Erfindung wird dies dadurch erreicht, dass an den Enden der aufeinander folgenden Hohlräume jeweils abwechselnd Aussparungen ausgeführt sind, wodurch ein durchgehender Hohlraum gebildet wird und dass der durchgehende Hohlraum von außen be- oder entlüftbar ist.According to the invention, this is achieved in that at the ends of the successive cavities in each case alternately recesses are made, whereby a continuous cavity is formed and that the continuous cavity from the outside can be ventilated or ventilated.
Eine derartige Matratze ist gut belüftbar. Weiters entsteht der Vorteil, das der Matratzenkern im Winter mit Warmluft beheizt und im Sommer mit Kaltluft gekühlt werden kann. Durch die Ausbildung und Anordnung der Spiralfeder entsteht eine durchgehende flexible Verstärkung des Hohlraums. Hierdurch ergibt sich der besondere Vorteil das die Hohlräume besonders groß ausgeführt werden können und dadurch ein ausreichendes Luftvolumen gebildet werden kann. Weiters verhindert die erfindungsgemäße Spiralfeder ein Zusammenquetschen der Hohlräume unter jeder Belastung, wodurch immer eine seitliche Durchlüftung gewährleistet ist. Dadurch ergibt sich ein weiterer Vorteil, nämlich jener, dass auf den aufwendigen Lattenrost verzichtet werden kann. Die Ausbildung und Dimensionierung der erfindungsgemäßen Spiralfeder ist so ausgelegt, das die Federkraft der liegend beanspruchten Spiralfeder der Rückdruckkraft des durch den Hohlraum wegfallenden Schaumstoffs entspricht, wodurch ein optimaler Liegekomfort ohne einsinken im Holraumbereich gewährleistet ist.Such a mattress is well ventilated. Furthermore, there is the advantage that the mattress core can be heated in the winter with warm air and cooled in the summer with cold air. The design and arrangement of the coil spring creates a continuous flexible reinforcement of the cavity. This results in the particular advantage that the cavities can be made very large and thus a sufficient volume of air can be formed. Furthermore, the coil spring according to the invention prevents a crushing of the cavities under any load, whereby a lateral ventilation is always ensured. This results in a further advantage, namely that that can be dispensed with the elaborate slatted frame. The design and dimensioning of the coil spring according to the invention is designed so that the spring force of the horizontally loaded coil spring corresponds to the back pressure force of the cavity disappearing foam, whereby optimal comfort is ensured without sinking in the hollows.
Eine besonders vorteilhafte Ausgestaltung der Erfindung wird dadurch erreicht, dass die Spiralfedern aus einem Faserverbundwerkstoff bestehen.A particularly advantageous embodiment of the invention is achieved in that the coil springs consist of a fiber composite material.
Weitere Vorteile ergeben sich dadurch, dass die Spiralfedern der Kontur der Hohlräume angepasst sind und/oder dass die Spiralfedern aus einem Bandmaterial hergestellt sind.Further advantages result from the fact that the coil springs are adapted to the contour of the cavities and / or that the coil springs are made of a strip material.
In Weiterführung der Erfindung kann vorgesehen sein, dass die Bezugsstoffe nur durch eine Vernadelung mit dem Schaumstoffkern verbunden sind, wodurch eine hochwertige Mattratze ohne Klebstoffe hergestellt werden kann.In continuation of the invention can be provided that the cover fabrics are connected only by a needling with the foam core, whereby a high-quality mattress can be made without adhesives.
Eine besondere Ausführungsform liegt auch dann vor, wenn dem erfindungsgemäßen Matratzenkern bei der Herstellung des Schaumstoffkerns oder der Spiralfeder ein Keramikpulver mit eingeschlossenen effektiven Mikroorganismen zugesetzt wird. Der besondere Vorteil dieser Ausführungsform besteht darin, das die revitalisierende und reinigende Wirkung der langwelligen Infrarotstrahlung der Keramik sich auf den Benutzer überträgt und das durch die im Keramikpulver eingeschlossenen aber aktiven effektiven Mikroorganismen eine fäulnistilgende und fäulnisverhindernde Wirkung haben, wodurch ein biologisch Aktiver und geruchsloser Matratzenkern geschaffen wird.A particular embodiment is also present when a ceramic powder with trapped effective microorganisms is added to the mattress core according to the invention in the manufacture of the foam core or the coil spring. The particular advantage of this embodiment is that the revitalizing and cleaning effect of the long-wave infrared radiation of the ceramic is transferred to the user and have a fäulnistilgende and fäulnisverhindernde effect by enclosed in the ceramic powder but active effective microorganisms, creating a biologically active and odorless mattress core becomes.
Vorzugsweise kann vorgesehen sein, dass ein aktives Keramikpulver, nach Prof. Teruo Higa, EMIKO- GmbH D53881 Euskirchen beigemengt wird.Preferably, it can be provided that an active ceramic powder, according to Prof. Teruo Higa, EMIKO GmbH D53881 Euskirchen is added.
