Description

Die Erfindung betrifft ein Federelement einer Unterfederung eines Sitz- oder Liegemöbels aus einem Fußteil zur Anordnung an einen Rahmen, auf einem Holm oder auf einer Unterlage, einem Kopfteil zur Aufnahme von Enden von Federleisten eines Lattenrostes oder einer Auflagerfläche, insbesondere für Matratzen, und einem dazwischen angeordneten Grundfederelement mit mindestens einer Ausnehmung mit einem Innenboden und einer Innendecke und einem darin angeordneten Zusatzfederelement.The invention relates to a spring element of a spring base of seating or reclining furniture from a foot section for arrangement on a frame, on a spar or on a base, a head part for receiving ends of slats of a slatted frame or a support surface, especially for mattresses, and one in between arranged base spring element with at least one recess with an inner bottom and an inner ceiling and an additional spring element arranged therein.

Es ist ein Matratzensystem bekannt, EP 0401712 B1, welches Tragelemente enthält, die elastische Stützelemente aus Rohrabschnitten aufweisen, in denen als Zusatzfederelemente Schaumstoffzylinder oder Schraubenfedern eingesetzt sind, wobei der konstruktive Aufwand sehr erheblich und dadurch das gesamte Federelement sehr unwirtschaftlich ist. Weiterhin lässt sich die Federrate des Federelementes hier nur begrenzt beeinflussen.A mattress system is known, EP 0401712 B1, which supports contains, which have elastic support elements from pipe sections, in which as additional spring elements Foam cylinders or coil springs are used, the constructive effort very significant and therefore the entire spring element very uneconomical is. Furthermore, the spring rate of the spring element can only be limited here influence.

Aufgabe der Erfindung ist es, ein insgesamt verbessertes Federelement einer Unterfederung eines Sitz- oder Liegemöbels zur Verfügung zu stellen, insbesondere eines, bei dem das Federungs- und/ oder Dämpfungsverhalten weiter optimiert ist, welches jedoch trotzdem wirtschaftlich herstellbar und auch einfach recycelbar ist.The object of the invention is an overall improved spring element To provide spring support for seating or reclining furniture, in particular one in which the suspension and / or damping behavior is further optimized, which, however, can still be produced economically and is also easy to recycle.

Die Lösung dieser Aufgabe wird erfindungsgemäß dadurch gelöst, dass das Kopfteil, das Fußteil und das Grundfederelement aus elastischem Material und das Zusatzfederelement als elastischer Hohlkörper ausgebildet ist, der mindestens in seiner Einbaulage einen nach außen abgeschlossenen, als Fluidpolster ausgebildeten Innenraum aufweist. Durch die Verwendung zweier identischer oder unterschiedlich harter Kunststoffkomponenten und einer der Belastung und der gewünschten Federfunktion angepassten Formgebung und technischer Ausgestaltung der einzelnen Bauteile, können die Aufgaben eines Federelementes optimal verteilt werden.According to the invention, this object is achieved in that the Headboard, the footboard and the basic spring element made of elastic material and that Additional spring element is designed as an elastic hollow body, at least in its Installation position an interior sealed off as a fluid cushion having. By using two identical or different hard ones Plastic components and one of the load and the desired spring function adapted shape and technical design of the individual components the tasks of a spring element are optimally distributed.

Vorteilhafte Ausgestaltungen des Gegenstandes der Erfindung ergeben sich mit und in Kombination aus den Unteransprüchen.Advantageous refinements of the subject matter of the invention also result and in combination from the subclaims.

Beispielsweise kann eine weniger elastische, harte Komponente entweder die Lagerung der Enden von Federleisten von Bettlattenrosten als Kopfteil und/ oder auch die Schnappfunktion auf Tragbolzen zur Festlegung des Federelementes an einem Rahmen oder auf einem Holm als Fußteil des Federelementes übernehmen. Alternativ kann das Kopfteil tellerförmig als Auflagerfläche für Matratzen ausgebildet sein, wobei insgesamt alle drei Bauteile Fußteil, Kopfteil und Grundfederelement aus einem einteiligen Spritzgussteil hergestellt sein können, welches eine eigene Grundelastizität aufweist.For example, a less elastic, hard component can either be Storage of the ends of slats of bed slatted frames as a headboard and / or the snap function on support bolts to fix the spring element on one Take over frame or on a spar as the foot part of the spring element. alternative the head part can be plate-shaped as a support surface for mattresses, wherein a total of all three components foot part, head part and basic spring element from a one-piece Injection molded part can be made, which has its own basic elasticity.

Einen wesentlichen Teil der Feder- und Dämpfungsarbeit leistet bei einer solchen bevorzugten Ausführungsform jedoch das Zusatzfederelement, welches als hochelastischer Hohlkörper ausgebildet ist, der in unterschiedlichen Shore-Härtegraden zur Verfügung gestellt und je nach Wandstärke des Hohlkörpers und verwendetem Fluid innerhalb des Innenraumes mit beliebigen Federeigenschaften versehen werden kann, sodass das gesamte Federelement durch die Kombination der unterschiedlichen Kunststoffe und die Kombination mehrerer Federsysteme mit einer beliebig anpassbaren Federrate, sei es degressiv, linear oder progressiv ausgestattet werden kann. Da die beiden oder auch weitere Kunststoffarten nur formschlüssig miteinander verbunden sind, lassen sich, falls das Federelement einmal receycelt werden soll, die einzelnen Bauteile ohne weiteres voneinander trennen, sodass diese Bauteile höchst rein wieder- oder weiterverwandt werden können.An essential part of the spring and damping work is done with such preferred embodiment, however, the additional spring element, which as a highly elastic Hollow body is formed, which is available in different degrees of Shore hardness and depending on the wall thickness of the hollow body and the fluid used within of the interior can be provided with any spring properties, so that the entire spring element through the combination of different plastics and the combination of several spring systems with an adjustable spring rate, be it degressive, linear or progressive. Since the two or other types of plastic are only positively connected to each other, if the spring element is to be recycled, the individual components without further ado separate from each other, so that these components can be reused or reused can be.

Die weniger elastische Komponente für das Fußteil, das Kopfteil und das Grundfederelement kann des Weiteren aus einem wirtschaftlich wesentlich günstigeren Material hergestellt werden als die bekannten Federelemente ohne Zusatzfederelement, sodass sich bei gestiegenem Gebrauchswert des Federelements kein wirtschaftlicher Nachteil aus dem etwas komplexeren Aufbau resultiert. Des Weiteren lässt sich das Federelement durch einfachen Werkzeugumbau bzw. Änderung als Endpunktlager für Federleisten oder für die punktuelle Einzelunterfederung verwenden, sodass sich auf höchst wirtschaftliche Art und Weise die unterschiedlichsten Federelemente mit den unterschiedlichsten Federkennraten herstellen lassen.The less elastic component for the foot part, the head part and the basic spring element can also be made of an economically much cheaper material are produced as the known spring elements without additional spring element, so that there is no economic disadvantage when the spring element increases in use value results from the somewhat more complex structure. Furthermore, the spring element by simple tool modification or change as end point bearing for female connectors or use for selective individual spring suspension, so that it is highly economical Way the most diverse spring elements with the most varied Have spring characteristics established.

Denkbar ist jedoch auch eine vorteilhafte Ausführungsform, bei der zumindest das Grundfederelement oder auch das Kopf- und/ oder das Fußteil aus einem elastischeren Kunststoff hergestellt sein kann als das Zusatzfederelement, wenn dadurch eine noch weiter optimierte oder bevorzugte Federrate erzielt werden soll.However, an advantageous embodiment is also conceivable, in which at least the base spring element or the head and / or foot part from a more elastic Plastic can be made as the additional spring element, if this creates a even further optimized or preferred spring rate is to be achieved.

Gemäss einer speziellen Ausführungsform der Erfindung ist das Zusatzfederelement rotationssymmetrisch ausgebildet, etwa als Federbalg, oder aber, bei einer besonders vorteilhaften Ausführungsform, als kugelförmiges Element, welches sich bevorzugt auch in Grundfederelementen bekannter Federelemente einsetzen oder dort nachrüsten lässt.According to a special embodiment of the invention, the additional spring element rotationally symmetrical, such as bellows, or, in particular advantageous embodiment, as a spherical element, which is preferred also use in basic spring elements of known spring elements or retrofit them there leaves.

Das Zusatzfederelement lässt sich dabei vorteilhafterweise auf dem Innenboden, an der Innendecke oder auch an einer Seitenwandung der Ausnehmung eines Grundfederelementes anbringen, wobei es auch entsprechend einer weiteren vorteilhaften Ausführungsform von einem Innenboden und/oder der Innendecke des Grundfederelementes beabstandet angeordnet sein kann, sodass es erst nach einer Teilverformung des Grundfederelementes mit beansprucht wird, wodurch sich der Einfluss des Zusatzfederelementes auf die gesamt Federrate des Federelementes weiter beeinflussen lässt.The additional spring element can be advantageously on the inner floor, on the inner ceiling or on a side wall of the recess of a base spring element attach, it also according to a further advantageous embodiment from an inner floor and / or the inner ceiling of the base spring element can be arranged spaced so that it is only after a partial deformation of the Basic spring element is claimed, whereby the influence of the additional spring element can be further influenced on the overall spring rate of the spring element.

Entsprechend einer besonders vorteilhaften Ausgestaltung des Gegenstandes der Erfindung ist in der Ausnehmung des Grundfederelementes ein dort hineinragender Zapfen vorgesehen und im Hohlkörper eine korrespondierende Ausnehmung zur Aufnahme des Zapfens eingebracht, sodass das Zusatzfederelement einfach durch ein Aufsetzen auf den Zapfen montiert werden kann, ohne dass zusätzliche Werkzeuge oder Verbindungshilfsmittel benötigt werden.According to a particularly advantageous embodiment of the object the invention is in the recess of the base spring element protruding there Pin provided and a corresponding recess for receiving in the hollow body of the pin, so that the additional spring element simply by putting it on can be mounted on the pin without additional tools or Connection tools are needed.

Von besonderer Bedeutung ist weiterhin die Ausführung von Zapfen und Ausnehmung mit aufeinander abgestimmten Außen- und Innenmaßen, sodass entweder bereits durch die Montage oder aber erst bei einer Belastung des Federelementes mit einer Kraft das Innere des Hohlkörpers luftdicht gegen die Umgebung abgeschlossen wird, sodass im Innenraum des Zusatzfederelementes ein Luftpolster entsteht, welches über seine Kompressibilität einen weiteren Beitrag zur Federrate des Federelementes liefert.Of particular importance is still the design of the pin and recess with coordinated external and internal dimensions, so that either already during assembly or only when the spring element is loaded a force the interior of the hollow body is sealed airtight against the environment is so that an air cushion is created in the interior of the additional spring element, which via its compressibility a further contribution to the spring rate of the spring element supplies.

Denkbar ist es jedoch auch, den Innenraum des Zusatzfederelementes als allseitig geschlossenen Raum auszubilden und als Fluid nicht Luft sonder ein Edelgas, ein Gasgemisch, ein Gel oder auch eine Flüssigkeit einzufüllen, wobei bei den gelförmigen oder flüssigen Füllungen, welche in der Regel inkompressibel sind, die Federwirkung im Wesentlichen von der Form und dem Material des Zusatzfederelementes abhängig ist.However, it is also conceivable for the interior of the additional spring element to be on all sides form a closed space and as a fluid not air but a noble gas Gas mixture to fill a gel or a liquid, with the gel or liquid fillings, which are usually incompressible, the spring action in the Is essentially dependent on the shape and material of the additional spring element.

Bei einer anderen vorteilhaften Ausgestaltung des Gegenstandes der Erfindung weist das Fußteil zwei voneinander beabstandete Bolzenaufnahmen auf, die auf parallel zueinander angeordneten Bolzen oder Stangen aus Rundmaterial aufgesetzt sind, wobei sich das gesamte Fußteil von einer vorherbestimmten Kraftbeaufschlagung durch eine elastische Verformung um die Bolzen oder Stangen herum verdrehen kann, wodurch ein weiteres Federsystem zur Verfügung gestellt wird, welches in der Kombination mit den anderen Federsystemen des Grundfederelementes und des Zusatzfederelementes optimal abgestimmt werden kann.In another advantageous embodiment of the subject of the invention the foot part has two spaced-apart bolt receptacles that are parallel Bolts or rods of round material arranged to each other are placed, whereby the entire foot part of a predetermined application of force by a elastic deformation around the bolts or rods can twist, creating a additional spring system is provided, which in combination with the other spring systems of the basic spring element and the additional spring element optimal can be coordinated.

Als weitere vorteilhafte Maßnahme zur Beeinflussung der Federrate eines Federelementes lässt sich eine Ausführungsform hervorheben, die mehr als ein Zusatzfederelement aufweist, welches in Parallel- oder in Reihenschaltung im Grundfederelement des Federelementes angeordnet sein kann, also beispielsweise zwei nebeneinander oder vier auf den Ecken eines Quadrats angeordnete Zusatzfederelemente, die sich etwa unterhalb einer Auflagerfläche für Matratzen abstützen oder aber auch als Anordnung von mehreren Zusatzfederelementen übereinander, sodass sich deren absoluter Federweg addiert.As a further advantageous measure for influencing the spring rate of a spring element can be emphasized an embodiment that more than an additional spring element has which in parallel or in series in the basic spring element of the spring element can be arranged, for example two next to each other or four additional spring elements arranged on the corners of a square, located approximately below a support surface for mattresses or as an arrangement of several additional spring elements one above the other, so that their absolute spring travel added.
