Description

Die vorliegende Erfindung betrifft ein Federelement gemäß dem Oberbegriff des Anspruchs 1.The present invention relates to a spring element according to the preamble of claim 1.

Bekannte Federelemente werden beispielsweise als Teil einer Untermatratze mit einer Vielzahl von über mindestens einen 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 bringen den Vorteil einer quasi punktelastischen Abstützung mit sich.Known 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 an upper mattress or as a spring core of a mattress top. In sub-mattresses, they replace the conventional spring strips in the corresponding areas and offer the advantage of a virtually point-elastic support.

Die US 6 477 727 B 1 offenbart ein Federelement gemäß dem Oberbegriff des Anspruchs 1. Weiter offenbaren die WO 2005/048781 und die DE 20 2005 013 020 Federelemente für Matratzen.The US Pat. No. 6,477,727 B 1 discloses a spring element according to the preamble of claim 1. Next discloses the WO 2005/048781 and the DE 20 2005 013 020 Spring elements for mattresses.

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 durch ein Federelement mit den Merkmalen des Anspruchs 1 gelöst. Bevorzugte Weiterbildungen und Ausführungsformen der Erfindung sind in den abhängigen Ansprüchen angegeben.This object is achieved by a spring element with the features of claim 1. Preferred developments and embodiments of the invention are specified in the dependent claims.

Bei dem erfindungsgemäßen Federelement sind die außenliegenden Teile jeweils über eine eigene Feder am Fuß abgestützt und die Verbindungsteile umfassen zumindest teilweise den jeweils zugehörigen außen liegenden Teil der Kopfplatte.In the spring element according to the invention, the outer parts are each supported by a separate spring on the foot and the connecting parts comprise at least partially the respectively associated outer part of the top plate.

Durch die erfindungsgemäße Ausgestaltung können die außen liegenden Teile der Kopfplatte des Federelements im Wesentlichen unabhängig voneinander einfedern. Dadurch ergibt sich eine entsprechend höhere Auflösung einer Untermatratze, nämlich entsprechend der Anzahl der außen liegenden Teile, während bei herkömmlichen Federelementen die Auflösung der Anzahl der Federelemente entspricht.Due to the configuration according to the invention, the outer parts of the top plate of the spring element can spring in substantially independently of one another. This results in a correspondingly higher resolution of a lower mattress, namely corresponding to the number of outer parts, while in conventional spring elements corresponds to the resolution of the number of spring elements.

Durch Anformen der außen liegenden Teile an den zentralen Teil können die Herstellungskosten weiter gesenkt werden. Eine weitere Kostensenkung ergibt sich dadurch, dass das zentrale Teil nicht separat abgestützt ist.By molding the external parts to the central part, the manufacturing costs can be further reduced. Another cost reduction results from the fact that the central part is not supported separately.

Alle außen liegenden Teile weisen bevorzugt ein eigenes Verbindungsteil zum zentralen Teil auf. Dadurch kann die unabhängige Einfederung der außen liegenden Teile gegenüber dem zentralen Teil und den anderen außen liegenden Teilen weiter verbessert werden.All external parts preferably have their own connection part to the central part. As a result, the independent deflection of the outer parts relative to the central part and the other outer parts can be further improved.

Die Verbindung der außen liegenden Teile mit dem zentralen Teil erfolgt insbesondere über mindestens einen Steg. Damit kann in vorteilhafter Weise die gewünschte Beweglichkeit der außen liegenden Teile gegenüber dem zentralen Teil erreicht werden.The connection of the outer parts with the central part takes place in particular via at least one web. Thus, the desired mobility of the outer parts relative to the central part can be achieved in an advantageous manner.

Nach einer besonderen Ausgestaltung können die außen liegenden Teile über zwei, insbesondere symmetrisch angeordnete Stege mit dem zentralen Teil verbunden sein. Dies fördert ein im Wesentlichen senkrechtes Einfedern der außen liegenden Teile zur Ebene der Kopfplatte. Die Stege können dabei abgewinkelt oder spiralförmig verlaufen. Eine bevorzugte Anordnung ergibt sich, wenn vier außen liegende Teile mit einem zentralen Teil verbunden sind. Es können aber auch mehr als vier außen liegende Teile oder auch nur drei außen liegende Teile vorgesehen sein. Üblicherweise ist nur ein einziges zentrales Teil vorgesehen, es können aber auch zwei miteinander verbundene zentrale Teile vorgesehen sein.According to a particular embodiment, the outer parts can be connected via two, in particular symmetrically arranged webs with the central part. This promotes a substantially vertical compression of the outer parts to the top plate level. The webs can be angled or spiral. A preferred arrangement results when four external parts are connected to a central part. But it can also be provided more than four outer parts or even only three outer parts. Usually only a single central part is provided, but it can also be provided two interconnected central parts.

Weitere vorteilhafte Merkmale der Erfindung ergeben sich aus den Unteransprüchen, der nachfolgenden Beschreibung und den Zeichnungen.Further advantageous features of the invention will become apparent from the dependent claims, the following description and the drawings.

Das in Fig. 1 gezeigte Federelement umfasst einen Fuß 1, eine Kopfplatte 2 und einen die Kopfplatte 2 gegenüber dem Fuß 1 elastisch abstützenden Federkörper 3. Die Kopfplatte 2 umfasst einen zentralen Teil 4 und vier außen liegende Teile 5. Die außen liegenden Teile 5 sind jeweils über einen Verbindungsteil 6 mit dem zentralen Teil 4 verbunden. Die Verbindung ist dabei so ausgestaltet, dass die außen liegenden Teile 5 gegenüber dem zentralen Teil 4 senkrecht zur Ebene der Kopfplatte 2, also in Federrichtung I, absenkbar sind. Dies kann insbesondere durch die Stärke des Verbindungsteils 6, aber auch durch das Material des Verbindungsteils 6 gewährleistet sein.This in Fig. 1 spring element shown comprises a foot 1, a top plate 2 and a head plate 2 with respect to the foot 1 elastically supporting spring body 3. The top plate 2 comprises a central part 4 and four outer parts 5. The outer parts 5 are each via a connecting part. 6 connected to the central part 4. The connection is designed so that the outer parts 5 with respect to the central part 4 perpendicular to the plane of the top plate 2, ie in the spring direction I, are lowered. This can be especially due to the strength of the Connecting parts 6, but also be ensured by the material of the connecting part 6.

Bei dem Ausführungsbeispiel von Fig. 1 sind die Verbindungsteile 6 jeweils als Steg ausgebildet, wobei jeder außen liegende Teil 5 der Kopfplatte über zwei Stege 6 mit dem zentralen Teil 4 verbunden ist. Die Stege 6 sind dabei symmetrisch zum außen liegenden Teil 5 angeordnet und umfassen diesen derart, dass sie von seitlich außen an den jeweiligen außen liegenden Teil 5 angreifen. Die außen liegenden Teile 5, die Stege 6 und der zentrale Teil 4 sind jeweils aneinander angeformt.In the embodiment of Fig. 1 the connecting parts 6 are each formed as a web, wherein each outer part 5 of the head plate is connected via two webs 6 with the central part 4. The webs 6 are arranged symmetrically to the outer part 5 and include these such that they attack from the outside laterally to the respective outer part 5. The outer parts 5, the webs 6 and the central part 4 are each formed on each other.

Jeder außen liegende Teil 5 ist durch eine eigene Feder 31, 32, 33, 34 am Fuß 1 abgestützt. Die Federn 31 bis 34 sind dabei jeweils durch zwei abgewinkelte Federarme gebildet.Each outer part 5 is supported by its own spring 3 1 , 3 2 , 3 3 , 3 4 at the foot 1. The springs 3 1 to 3 4 are each formed by two angled spring arms.

Bei dem Ausführungsbeispiel von Fig. 2 sind ebenfalls vier außen liegende Teile 5 vorhanden. Diese sind jeweils über einen Steg 6 mit dem zentralen Teil 4 verbunden, wobei die Stege 6 das jeweils zugehörige außen liegende Teil 5 halbkreisförmig umfassen. Auch hier sind die außen liegenden Teile 5 jeweils durch eine eigene Feder 31 bis 34 gegenüber dem Fuß 1 abgestützt, wobei die Federn 31 bis 34 als Wendelfedern ausgebildet sind.In the embodiment of Fig. 2 are also four outer parts 5 available. These are each connected via a web 6 with the central part 4, wherein the webs 6 include the respectively associated outer part 5 semicircular. Again, the outer parts 5 are each supported by a separate spring 3 1 to 3 4 relative to the foot 1, wherein the springs 3 1 to 3 4 are formed as helical springs.

Das Ausführungsbeispiel von Fig. 3 stimmt weitgehend mit dem Ausführungsbeispiel von Fig. 1 überein. Der Unterschied besteht im Wesentlichen darin, dass die außen liegenden Teile 5 durch die Enden der Stege 6 selbst gebildet sind.The embodiment of Fig. 3 is largely consistent with the embodiment of Fig. 1 match. The difference is essentially that the outer parts 5 are formed by the ends of the webs 6 itself.

Das Ausführungsbeispiel von Fig. 4 stimmt ebenfalls weitgehend mit dem Ausführungsbeispiel von Fig. 2 überein. Der Unterschied besteht im Wesentlichen in der Form der außen liegenden Teile 5 und der Länge der Stege 6, sowie der Größe des zentralen Teils 4.The embodiment of Fig. 4 is also largely consistent with the embodiment of Fig. 2 match. The difference is in Substantially in the form of the outer parts 5 and the length of the webs 6, and the size of the central part. 4

Bei der in Fig. 5 dargestellten Kopfplatte sind die außen liegenden Teile 5 durch einen ringförmig geschlossenen Steg 6 mit dem zentralen Teil 4 verbunden. Die Verbindungsstelle 7 zwischen den Stegen 6 und dem jeweils zugehörigen außen liegenden Teil 5 befindet sich dabei am äußeren Rand des außen liegenden Teils 5.At the in Fig. 5 shown top plate, the outer parts 5 are connected by an annularly closed web 6 with the central part 4. The connection point 7 between the webs 6 and the respectively associated outer part 5 is located at the outer edge of the outer part. 5

Bei der in Fig. 6 dargestellten Kopfplatte sind die außen liegenden Teile 5 jeweils wieder über zwei Stege 6 mit dem zentralen Teil 4 verbunden, wobei die Stege 6 seitlich an dem jeweiligen außen liegenden Teil 5 angreifen und symmetrisch zu diesem angeordnet sind. Benachbarte Stege 6 sind außerdem jeweils teilweise aneinander angeformt.At the in Fig. 6 2, the outer parts 5 are each again connected via two webs 6 to the central part 4, wherein the webs 6 laterally engage the respective outer part 5 and are arranged symmetrically to this. Adjacent webs 6 are also partially formed in each case in each case.
