Abstract

The element has a spring body (2) arranged on a base (1), and a head plate (3), which consists of two parts (3-1 to 3-4) connected together, where the parts are movable against each other. The spring body has four spring arms, where one end of the spring arm is connected with a foot and another end of the spring arm is connected with parts of the head plate. Connection parts (4-1 to 4-4) are provided at an outer edge of the head plate in a tight connected and compressed compact manner around a transverse axis to a connection line.

Description

Die vorliegende Erfindung betrifft ein Federelement für eine Federkernmatratze oder eine Untermatratze mit einem Fuß, einem auf dem Fuß angeordnetem Federkörper und einer Kopfplatte, die mindestens zwei miteinander verbundene Teile aufweist, die jeweils für sich federnd abgestützt und gegeneinander beweglich sind, wobei die Verbindung zwischen den Teilen zug- und stauchfest, um mindestens eine Querachse zur Verbindungslinie jedoch flexibel ausgebildet ist.The present invention relates to a spring element for a spring mattress or a mattress with a foot, arranged on the foot spring body and a head plate having at least two interconnected parts, each spring-supported and movable against each other, the connection between the Share tensile and crush resistant, but at least one transverse axis to the connecting line is flexible.

Derartige Federelemente werden beispielsweise als Teil einer Untermatratze mit einer Vielzahl von über mindestens einem Teil der Untermatratze verteilt angeordneten, voneinander unabhängigen derartigen Federelementen zur Abstützung einer Obermatratze oder als Federkern einer Obermatratze eingesetzt. In Untermatratzen ersetzen sie in den entsprechenden Bereichen die herkömmlichen Federleisten und bringenden Vorteil einer quasi punktelastischen Abstützung mit sich.Such spring elements are used, for example, as part of a lower mattress with a plurality of distributed over at least a portion of the lower mattress, arranged independently of each other such spring elements for supporting a mattress top or as a spring core of a mattress top. In sub-mattresses they replace in the corresponding areas of the conventional spring strips and bringing advantage of a virtually point-elastic support with it.

Bei herkömmlichen Federelementen der genannten Art sind die Kopfplatten üblicherweise als separate Teile vorgesehen, da sie andere Anforderungen erfüllen müssen als der Federkörper. Insbesondere sind die Kopfplatten starr ausgebildet, um eine sichere Auflagefläche zu bieten. Die Kopfplatten bestehen daher üblicherweise aus hartem Kunststoffmaterial, während die Federkörper aus weicherem Kunststoff bestehen, um die gewünschte Federelastizität zu bewirken.In conventional spring elements of the type mentioned, the top plates are usually provided as separate parts, since they have to meet different requirements than the spring body. In particular, the top plates are rigid to provide a secure bearing surface. The top plates are therefore usually made of hard plastic material, while the spring body made of softer plastic to effect the desired spring elasticity.

Der Erfindung liegt die Aufgabe zugrunde, Federelemente der genannten Art zu verbessern. Insbesondere soll eine gute Abstützung mit möglichst geringen Herstellungskosten erreicht werden.The invention has for its object to improve spring elements of the type mentioned. In particular, good support should be achieved with the lowest possible manufacturing costs.

Diese Aufgabe wird dadurch gelöst, dass die Verbindungen jeweils zwischen zwei benachbarten Teilen der Kopfplatte vorgesehen sind, insbesondere am Außenrand der Kopfplatte.This object is achieved in that the connections are respectively provided between two adjacent parts of the top plate, in particular on the outer edge of the top plate.

Bei einer Verbindung der Teile der Kopfplatte über eine zentrale Verbindung ergibt sich eine relativ starke Verformung, da der Abstand in der Mitte zwischen den Teilen gering ist. Dies wird noch verstärkt, wenn jeweils mehr als zwei Kopfplattenteile miteinander verbunden sind. Erfindungsgemäß werden daher jeweils nur zwei Teile miteinander verbunden, und zwar insbesondere randseitig. Aber auch eine Verbindung etwa in der Mitte zwischen den beiden benachbarten Kopfplattenteilen wäre möglich. Nicht verbunden sind dagegen weiter entfernt voneinander liegende Teile der Kopfplatte. Insbesondere findet erfindungsgemäß keine Verbindung über Kreuz, also über den Mittenbereich der Kopfplatte statt.In a compound of the parts of the top plate via a central connection results in a relatively strong deformation, since the distance in the middle between the parts is low. This is reinforced when more than two headboard parts are connected to each other. According to the invention therefore only two parts are connected to each other, in particular at the edge. But even a connection in the middle between the two adjacent headboard parts would be possible. Not connected, however, are more distant parts of the top plate. In particular, according to the invention, there is no connection via the cross, that is to say over the middle region of the top plate.

Die Verbindung zwischen den Kopfplattenteilen ist flexibel, um eine Relativbewegung der Teile gegeneinander zu ermöglichen. Die Verbindung ist jedoch in Verbindungsrichtung starr, dass heißt zug- und stauchfest, so dass sich der Abstand der Plattenteile voneinander bei Belastung nicht verändert. Die Plattenteile verkippen lediglich gegeneinander. Die Flexibilität ist folglich lediglich um mindestens eine Querachse zur Verbindungslinie gegeben. Die Verbindung selbst verbiegt sich also, wird aber bei Belastung der Kopfplattenteile weder verlängert noch verkürzt.The connection between the head plate parts is flexible to allow relative movement of the parts against each other. However, the connection is rigid in the direction of connection, that is tensile and crush resistant, so that the distance between the plate parts does not change from each other under load. The plate parts tilt only against each other. The flexibility is therefore given only by at least one transverse axis to the connecting line. The connection itself bends so, but is not extended or shortened when loading the headboard parts.

Ein Ausführungsbeispiel der Erfindung ist in der Zeichnung dargestellt und wird nachfolgend beschrieben. Es zeigen, jeweils in schematischer Darstellung,

  • Fig. 1 eine perspektivische Ansicht eines erfindungsgemäßen Federelements und
  • Fig. 2 eine Draufsicht auf die Oberseite des Federelements von Fig. 1.
An embodiment of the invention is illustrated in the drawing and will be described below. They show, in each case in a schematic representation,
  • Fig. 1 a perspective view of a spring element according to the invention and
  • Fig. 2 a plan view of the top of the spring element of Fig. 1 ,

Das dargestellte Federelement umfasst einen Fuß 1, einen Federkörper 2 und eine Kopfplatte 3. Die Kopfplatte 3 besteht aus vier Teilen 31 bis 34. Der Federkörper 2 weist vier Federarme 21 bis 24 auf, die jeweils mit ihrem einen Ende mit dem Fuß 1 und mit ihrem anderen Ende mit einem Teil 31 bis 34 der Kopfplatte 3 verbunden sind.The spring element shown includes a base 1, a spring body 2 and a top plate 3. The top plate 3 is composed of four parts 3 1 to 3. 4 The spring body 2 has four spring arms 2 1 to 2 4 , which are each connected at one end to the foot 1 and at the other end to a part 3 1 to 3 4 of the top plate 3.

Die Kopfplattenteile 31 bis 34 sind über Verbindungsteile 41 bis 44 miteinander verbunden. Und zwar sind jeweils zwei nebeneinander liegende Teile 31 und 32, 32 und 33, 33 und 34, 34 und 31 über je eine Verbindung 41 bis 44 miteinander verbunden. Die Verbindungen 41 bis 44 sind dabei im Bereich des Außenrandes der Kopfplatte 3 angeordnet und leicht geschwungen ausgeführt.The headboard parts 3 1 to 3 4 are connected via connecting parts 4 1 to 4 4 together. Namely, two juxtaposed parts 3 1 and 3 2 , 3 2 and 3 3 , 3 3 and 3 4 , 3 4 and 3 1 via one connection 4 1 to 4 4 are connected to each other. The compounds 4 1 to 4 4 are arranged in the region of the outer edge of the top plate 3 and slightly curved.

Selbstverständlich kann die Kopfplatte auch eine andere Form aufweisen. Sie kann nur zwei oder drei Teile oder auch mehr als vier Teile aufweisen. Die Verbindung zwischen jeweils zwei benachbarten Kopfplattenteilen kann auch weiter in der Mitte vorgesehen sein. Außerdem kann die Verbindung auch nicht geschwungen ausgeführt sein. Als Material kommt insbesondere Kunststoff in Betracht. Die Kopfplatte kann als separates Teil ausgebildet oder einstückig mit dem Rest des Federelementes ausgebildet sein. Ebenso kann das Fußteil 1 an den Federkörper 2 angeformt oder separat ausgeführt sein. Der Federkörper 1 kann auch in anderer Form ausgestaltet sein als mit den dargestellten Federarmen. Die Teile der Kopfplatte 3 können in sich starr oder ebenfalls flexibel ausgebildet sein. Es ist auch möglich ein Doppelfederelement auszubilden, welches aus zwei Federelementen besteht, die spiegelsymmetrisch an ihrem Fuß 1 miteinander verbunden sind. Ein solches Element ist insbesondere als Federkern für eine Matratze geeignet.Of course, the top plate may also have a different shape. It can only have two or three parts or even more than four parts. The connection between each two adjacent headboard parts may also be provided further in the middle. In addition, the connection can not be executed curved. As a material in particular plastic comes into consideration. The top plate may be formed as a separate part or formed integrally with the rest of the spring element. Likewise, the foot part 1 can be integrally formed on the spring body 2 or be carried out separately. The spring body 1 can also be configured in a different form than with the illustrated spring arms. The parts of the top plate 3 may be rigid or flexible. It is also possible to form a double spring element, which consists of two spring elements, which are mirror-symmetrically connected to one another at their foot 1. Such an element is particularly suitable as a spring core for a mattress.
