Description
Die Erfindung betrifft ein Auflagerelement einer Sitz- oder Liegemöbelunterfederung gemäß dem Oberbegriff des Hauptanspruches.The invention relates to a support element of a seat or Liegemöbelunterfederung according to the preamble of the main claim.
Aus der
Es ist des Weiteren ein Federelement für Sitz- und Liegemöbel bekannt,
Bekannt ist ebenfalls ein Latten-Lagerkörper,
Aufgabe der Erfindung ist es, entgegen diesem vorbenannten Stand der Technik, ein Auflagerelement einer Sitz- oder Liegemöbelunterfederung mit einer neuartigen kippstabileren Federung zur Verfügung zu stellen, dass wirtschaftlicher herstellbar sowie leichter und schneller montierbar ist, ebenso wie eine wirkungsvolle Härteverstellung vorzusehen, die ebenfalls schnell und einfach im Auflagerelement montiert und leicht in und außer Betrieb gesetzt werden kann.Object of the invention is to provide, contrary to this prior art, a support element of a seat or Liegemöbelunterfederung with a novel tilt-stable suspension available that is more economical to produce and easier and faster to install, as well as an effective hardness adjustment provided, which also mounted quickly and easily in the support element and can be easily put into and out of operation.
Die Lösung dieser Aufgabe erfolgt in Verbindung mit den Merkmalen des Oberbegriffes erfindungsgemäß im Zusammenhang mit den Merkmalen des kennzeichnenden Teils des Hauptanspruches insbesondere dadurch, dass das Auflagerelement mit einem Tragelement mit einem Fußteil und mindestens zwei sich davon radial und schräg nach oben in Richtung einer starren Auflagerplatte erstreckenden Armen so ausgebildet ist, dass jeder Arm unterteilt ist in einen quasi starren Tragarm-Abschnitt, der sich vom Fußteil ausgehend bis über die Hälfte seiner Gesamtlänge erstreckt und einen elastischen Tragfeder-Abschnitt, der sich dem Tragarm-Abschnitt anschließt und nach oben innen zurückgeformt ist, wobei dessen oberen nach innen gerichteten Enden in die Auflagerplatte münden. Die Tragarm-Abschnitte nehmen also im wesentlichen nicht aktiv an einer elastischen Verformung teil, sondern nur die vorderen Tragfeder-Abschnitte, die aufgrund ihrer Vielzahl aufzunehmender Verformungen in Breite und Höhe verschiedenartigen Belastungen wie Zug, Druck, Schub, Biegung und Torsion ausgesetzt sind. Dieses Auflagerelement ist aufgrund der weitgehenden Steifheit des unteren Bereiches seines Tragelementes sehr stabil und bietet eine feste Auflagerungsmöglichkeit etwa für Matratzen von Liegemöbeln, ohne seitlich auswandern zu können.The solution of this object is achieved in conjunction with the features of the preamble according to the invention in connection with the features of the characterizing part of the main claim in particular by the fact that the support element with a support member having a foot and at least two of them radially and obliquely upwards in the direction of a rigid support plate extending arms is formed so that each arm is divided into a quasi-rigid arm portion, which extends from the foot part to over half of its total length and a resilient suspension spring portion which adjoins the support arm portion and formed back up inside is, with its upper inboard ends open into the support plate. Thus, the support arm sections do not actively participate in elastic deformation, but only the front suspension spring sections, which are subjected to various loads such as tension, compression, thrust, flexure and torsion due to their large amount of deformations to be received in width and height. This support element is due to the substantial rigidity of the lower portion of its support element very stable and provides a firm Auflagerungsmöglichkeit about mattresses for bedding without being able to migrate laterally.
Die Auflagerplatte und das Tragelement sind dabei gemeinsam mit seinem Fußteil und den Armen einteilig ausgebildet und alle Bauteile bestehen entweder aus dem gleichen Material oder aber aus unterschiedlichen Materialien, wozu das Auflagerelement im Ko-Spritzgussverfahren hergestellt ist. Hierdurch lassen sich die Materialien technisch und wirtschaftlich besser den geforderten Funktionen und Anforderungen anpassen.The support plate and the support element are integrally formed together with its base and the arms and all components consist either of the same material or of different materials, including the support element is made by co-injection molding. As a result, the materials can be technically and economically better adapted to the required functions and requirements.
Weiterhin erfolgt die Lösung des Problems in besonders effektiver Weise dadurch, dass der Tragfeder-Abschnitt in zwei sich beidseitig einer Mittelachse jedes Armes erstreckende Bogenfedern aufgeteilt ist, die die Auflagerplatte stabiler lagern, als dies eine nur kurze Anlenkung eines schmalen nach innen gerichteten oberen Endes leisten könnte. Hier-durch lassen sich außermittige Kippbelastungen des Auflagerelementes deutlich besser abstützen, als dies bei bekannten Auflagerelementen der Fall ist.Furthermore, the solution of the problem is particularly effective in that the suspension spring portion is divided into two extending on both sides of a central axis of each arm bow springs, which store the support plate more stable than afford a short articulation of a narrow inwardly directed upper end could. Here-by can off-center tilting loads of the support element support much better than is the case with known support elements.
Weitere vorteilhafte Ausgestaltungen des Gegenstandes der Erfindung ergeben sich aus und in Kombination mit den nachfolgenden Unteransprüchen.Further advantageous embodiments of the subject matter of the invention will become apparent from and in combination with the following subclaims.
Die starren Tragarm-Abschnitte sind über ihre Länge vom Fußteil ausgehend über etwa die erste Hälfte ihrer Länge radial nach außen oben geschwungen und in der zweiten Hälfte ihrer Länge bis über eine horizontale Tangentialfläche hinaus nach außen und unten zurückgeschwungen und als flache breite Stege ausgebildet, wobei sie über äußere untere Versteifungsrippen in der ersten Hälfte ihrer Länge und/ oder über innere obere Versteifungsrippen in der zweiten Hälfte ihrer Länge gegen ein elastisches Verbiegen stabilisiert sind, so dass die Funktion des reinen Lastabtragens einer Belastung des Auflagerelementes auf das Fußteil und damit das Gestell eines Sitz- oder Liegemöbels gewährleistet ist. Die Bogenfedern des Tragfeder-Abschnittes weisen dabei etwa die halbe Breite der flachen Stege der Tragarm-Abschnitte auf und sind davon ausgehend absatzfrei weitergeführt, wobei die nach oben gerichtete Fläche des Tragarm-Abschnittes auch in jedem Tragfeder-Abschnitt stets nach oben gerichtet bleibt. Eine Belastung wird demnach nicht über eine Falte in einem Federarm aufgenommen, sondern vorteilhaft auf die gesamte Bogenfeder verteilt.The rigid support arm sections are swinging over their length from the foot starting over about the first half of their length radially outwardly upwardly and in the second half of their length to a horizontal tangential surface beyond outwardly and down swung back and formed as a flat wide webs, said they are stabilized against external lower stiffening ribs in the first half of their length and / or over inner upper stiffening ribs in the second half of their length against elastic bending, so that the function of pure load transfer of a load of the support element on the foot part and thus the frame of a Sitting or lying furniture is guaranteed. The bow springs of the suspension spring section in this case have approximately half the width of the flat webs of the support arm sections and are continued paragraph-free, with the upwardly directed surface of the support arm section always in each suspension spring section remains directed upward. A load is therefore not added via a fold in a spring arm, but advantageously distributed over the entire bow spring.
Gemäß einer besonders bevorzugten Ausführungsform der Erfindung ist an der Auflagerplatte ein Härteversteller entweder fest angeordnet, etwa eingeklippst oder aber drehgelagert, wobei er sich in einer Blockierstellung mindestens im belasteten Zustand des Auflagerelementes mit radialen und sich schräg nach unten erstreckenden Stützarmen auf den starren Tragarm-Abschnitten abstützt, was bevorzugt im Bereich der horizontalen Tangentialflächen der Tragarm-Abschnitte erfolgt, so dass nur vertikale Kräfte auf die Tragarm-Abschnitte übertragen werden.According to a particularly preferred embodiment of the invention, a hardness adjuster is either fixed, about clipped or rotatably mounted on the support plate, wherein it is in a blocking position at least in the loaded state of the support element with radial and obliquely downwardly extending support arms on the rigid support arm sections supported, which preferably takes place in the region of the horizontal tangential surfaces of the support arm sections, so that only vertical forces are transmitted to the support arm sections.
Die Stützarme sind bei einem drehgelagerten Härteversteller vorzugsweise löffelartig mit abgerundeten seitlichen Auflaufflächen ausgebildet, so dass sie bei der Drehung aus einer Ruheposition in eine Funktionsstellung auf die Tangentialflächen der Tragarm-Abschnitte bewegt werden können, ohne sich zu verhaken.The support arms are preferably formed like a spoon with rounded lateral casserole surfaces in a rotatably mounted hardness adjuster so that they rotate during rotation can be moved from a rest position to a functional position on the tangential surfaces of the support arm sections without getting caught.
Der drehgelagerte Härteversteller ist bevorzugterweise scheibenförmig ausgebildet und von oben in Ausnehmungen in der Auflagerplatte eingeklippst und weist gemeinsame obere Auflageflächen, beispielsweise für eine zu unterfedernde Matratze eines Sitz- oder Liegemöbels und gegenseitige Stützflächen mit der Auflagerplatte auf, ebenso wie seitliche Verriegelungsfortsätze an den Stützarmen, die bei der Montage nach einer elastischen Verformung unter die Auflagerplatte greifen und den Härteversteller nach oben verriegeln, ebenso wie zusätzliche Rastnasen, die entsprechende Funktionsflächen der Auflagerplatte von unten hintergreifen.The rotatably mounted hardness adjuster is preferably disc-shaped and clipped from above into recesses in the support plate and has common upper support surfaces, for example, a mattress to be unterfedernde a seat or reclining furniture and mutual support surfaces with the support plate, as well as lateral locking projections on the support arms, the engage during assembly after an elastic deformation under the support plate and lock the hardness adjuster up, as well as additional locking lugs, engage behind the corresponding functional surfaces of the support plate from below.
Vorzugsweise weist der Härteversteller so viele Stützarme auf, wie das Auflagerelement Arme besitzt. Es ist jedoch auch eine größere Anzahl von Stützarmen denkbar, die unterschiedliche Stützhöhen aufweisen könnten, ebenso wie die Anzahl der Tragarme größer ausgewählt werden kann, wenn beispielsweise bei symmetrischer Anordnung von vier Armen und ebenso symmetrischer Anordnung eines Härteverstellers mit nur zwei Stützarmen in die eine Richtung einer Unterfederung eine andere Federrate als in die dazu rechtwinklig gerichtete Richtung erzielt werden soll.Preferably, the hardness adjuster has as many support arms as the support element has arms. However, it is also a larger number of support arms conceivable that could have different support heights, as well as the number of support arms can be selected larger, for example, with symmetrical arrangement of four arms and equally symmetrical arrangement of a hardness adjuster with only two support arms in one direction a bottom spring another spring rate than in the direction perpendicular thereto should be achieved.
Entsprechend einer weiteren vorteilhaften Ausführungsform der Erfindung ist das Fußteil mit einem sich umgekehrt T-förmig nach unten erstreckenden Rastknochen ausgestattet, der stirnseitige Verrastungskerben aufweist, mit denen das Auflagerelement unmittelbar in eine aus Kunststoff bestehende Querlatte mit entsprechenden Aufnahmen für die Rastknochen eingesetzt und verriegelt werden kann, wobei in der Rastvorrichtung seitliche Anschlagflächen für den Rastknochen sowie stirnseitige Rastnasen zu seiner Drehverriegelung und damit auch des Auflagerelementes vorgesehen sind. Hierdurch wird die erforderliche Bauteilmenge weiter drastisch reduziert, da keine separaten Verbindungsteile zwischen dem Auflagerelement und einer Querlatte eingesetzt werden müssen, wodurch zusätzlich auch die Montage der Auflagerelemente in einem Rahmen einer Unterfederung wesentlich vereinfacht und beschleunigt ist.According to a further advantageous embodiment of the invention, the foot part is equipped with a reverse T-shaped downwardly extending latching bone having frontal Verrastungskerben with which the support element can be inserted directly into a plastic crossbar with corresponding receptacles for the latching bones and locked , wherein in the latching device lateral stop surfaces for the latching bone and frontal locking lugs are provided for its rotation lock and thus also of the support element. As a result, the required component quantity is further reduced drastically, since no separate connecting parts between the support element and a crossbar must be used, whereby in addition the mounting of the support elements in a frame of a lower suspension is significantly simplified and accelerated.

Das Auflagerelement besteht aus einer starren Auflagerplatte 1 und einem darunter einteilig angeordneten Tragelement mit einem Fußteil 11 und sich davon radial nach außen und nach oben erstreckenden Armen, die unterteilt sind in einen quasi starren Tragarm-Abschnitt 2, der sich vom Fußteil 11 ausgehend bis über die Hälfte seiner Gesamtlänge erstreckt und einen elastischen Tragfeder-Abschnitt 3, der sich daran anschließt. Der Tragfeder-Abschnitt 3 ist in zwei sich seitlich erstreckende Bogenfedern 9 aufgetrennt, die beide nach oben und innen zurückgeformt ausgebildet sind und deren oberen Enden voneinander beabstandet in die Auflagerplatte 1 münden und so eine kippstabile Lagerung bilden.The support member consists of a
Die starren Tragarm-Abschnitte 2 sind vom Fußteil 11 ausgehend über die erste Hälfte ihrer Länge radial nach außen oben geschwungen und über die zweite Hälfte ihrer Länge bis über eine horizontale Tangentialfläche 7 hinaus nach außen und unten zurückgeschwungen und als flache Stege ausgebildet, die über innere untere Versteifungsrippen 5 entlang der ersten Hälfte ihrer Länge und über äußere obere Versteifungsrippen 4 entlang der zweiten Hälfte ihrer Länge gegen ein Verbiegen stabilisiert sind, wobei sich die untere Versteifungsrippe 4 bis in den Bereich des Fußteiles 11 erstrecken kann, um auch dort einer elastischen Verformung entgegenzuwirken.The rigid
In dem Auflagerelement ist ein Härteversteller 6 verdrehbar gelagert, der in einer Blockierstellung mit radialen und nach schräg unten gerichteten Stützarmen 8 auf den Tangentialflächen 7 der Tragarm-Abschnitte 2 aufliegt, wobei die aufliegenden Stützarme 8 löffelartig mit abgerundeten seitlichen Auflaufflächen 10 versehen sind, so dass das in Betriebsetzen der Härteverstellung sicher erfolgen kann, ohne dass sich die Stützarme 8 an den Tragarm-Abschnitten 2 oder anderen Bauteilen des Auflagerelementes verrasten können. Der Härteversteller 6 ist insbesondere scheibenförmig ausgebildet und von oben in Ausnehmungen in der Auflagerplatte 1 eingeklippst und weist gemeinsame obere Auflagerflächen 12 mit den Auflagerflächen 14 der Auflagerplatte 1 auf, um beispielsweise darauf zu lagernde Matratzen großflächig zu unterstützen, ebenso wie der Härteversteller 6 und die Auflagerplatte 1 gegenseitige Stützflächen 15;25 besitzen, um einen gegenseitigen festen Sitz zu gewährleisten.In the support element a
Die Stützarme 8 weisen kleine seitliche Verriegelungsfortsätze 21 auf, die nach einer elastischen Verformung bei der Montage unter die Auflagerplatte 1 greifen und gemeinsam mit weiteren die Auflagerplatte 1 hintergreifenden Rastnasen 23 den Härteversteller 6 verriegeln. Die Verriegelungsfortsätze 21 besitzen nach oben gerichtete Nuten die gewährleisten, dass sich die Fortsätze 21 bei einer Montage elastisch nach innen verformen lassen, um anschließend die Ränder von Ausnehmungen in der Auflagerplatte 1 untergreifen zu können.The
