Description

Die vorliegende Erfindung betrifft ein Federelement nach dem Oberbegriff von Anspruch 1. Ein derartiges Federelement ist z.B. aus der FR-A-2 688 129 bekannt.The present invention relates to a spring element according to the preamble of claim 1. Such a spring element is e.g. known from FR-A-2 688 129.

Derartige Federelemente werden zur Abfederung von Bauteilen in im wesentlichen einer Federungsrichtung verwendet. Sofern die Belastung im wesentlichen auch nur in dieser Richtung erfolgt, kann die Auflage der Bauteile einfach durch Auflegen in Richtung dieser Federrichtung auf den Tragkörper des Federelementes erfolgen. Zur Fixierung des Bauteiles senkrecht zu dieser Federrichtung ist beispielsweise ein Zapfen vorgesehen, welcher in eine entsprechende Aufnahmeöffnung einfuhrbar ist. Dabei kann der Zapfen beispielsweise am Tragkörper vorgesehen sein und die Aufnahmeöffnung am Bauteil oder umgekehrt. Die eigentliche Auflage des Bauteiles auf den Tragkörper erfolgt dabei über eine im wesentlichen plane Fläche. Derartige Federelement werden nun hauptsächlich paarweise eingesetzt, um ein Bauteil translatorisch abzufedern, wobei an beiden Federelementen gleichzeitig gleiche Federwege auftreten. Solche Bauteile können beispielsweise Latten zur Bildung einer Sitz- oder Liegefläche von Möbeln, insbesondere Sitzmöbeln oder Betten, sein.Such spring elements are used to cushion components in essentially one direction of suspension. If the load is essentially only in this direction, the components can simply be placed on the support body of the spring element in the direction of this spring direction. To fix the component perpendicular to this spring direction, a pin is provided, for example, which can be inserted into a corresponding receiving opening. The pin can be provided on the support body, for example, and the receiving opening on the component or vice versa. The actual support of the component on the support body takes place over an essentially flat surface. Such spring elements are now mainly used in pairs to translationally cushion a component, with the same spring travel occurring simultaneously on both spring elements. Such components can be, for example, slats for forming a seating or lying surface of furniture, in particular seating furniture or beds.

Bei solchen Federelementen tritt nun ein Problem auf, wenn sich das Bauteil nicht nur parallel, translatorisch zur Federrichtung bewegt, sondern auch noch verschwenkt, d.h. bezüglich der Auflage auf den Tragkörper des Federlementes rotiert. Eine solche Bewegung führt zu Krafteinflüssen senkrecht zur Federrichtung und damit auch senkrecht zur Bewegungsrichtung des Tragkörpers des Federelementes. Dies kann einerseits zur Verkantung des Tragkörpers im Federelement führen, und damit einem Blockieren der Federwirkung, und andererseits im Auflagebereich zur Überbelastung des Auflageelementes führen, wie beispielsweise des Zapfens. Eine solche Überbelastung kann zu einer unerwünschten Geräuschbildung führen oder letztlich auch zum Bruch des Auflageelementes, wodurch das Bauteil vom Federelement abgleiten kann.A problem arises with such spring elements if the component not only moves parallel, translationally to the spring direction, but also pivots, ie with respect to the support on the supporting body of the spring element rotates. Such a movement leads to force influences perpendicular to the spring direction and thus also perpendicular to the direction of movement of the support body of the spring element. This can lead, on the one hand, to the canting of the supporting body in the spring element, and thus a blocking of the spring action, and, on the other hand, to overloading the support element, such as the pin, in the support area. Such an overload can lead to undesirable noise formation or ultimately to breakage of the support element, as a result of which the component can slide off the spring element.

Die Aufgabe der vorliegenden Erfindung bestand nun darin, ein Federelement zu finden, welches die genannten Probleme vermeidet, insbesondere auch eine Bewegung des Bauteiles senkrecht zur eigentlichen Federungsrichtung zulässt.The object of the present invention was to find a spring element which avoids the problems mentioned, in particular also permits movement of the component perpendicular to the actual direction of suspension.

Diese Aufgabe wird erfindungsgemäss durch die Merkmale des Anspruches 1 gelöst. Bevorzugte Ausführungsformen ergeben sich aus den weiteren Ansprüchen 2 bis 4. Insbesondere eignen sich derartige Federelemente nach Anspruch 5 für Sitz- und Liegemöbel.According to the invention, this object is achieved by the features of claim 1. Preferred embodiments result from the further claims 2 to 4. Such spring elements according to claim 5 are particularly suitable for seating and reclining furniture.

Indem die Auflagefläche und das Haltemittel senkrecht zur eigentlichen Federrichtung federnd angeordnet sind, können Kräfte und Bewegungen in dieser Richtung aufgenommen werden, ohne dass die eigentliche Federbewegung dadurch eingeschränkt oder behindert würde. Ebenfalls entfallen dadurch die bekannten Geräuschentwicklungen und auch eine Überlastung des Haltemittels wird dadurch vermieden.By the resilient surface and the holding means being arranged perpendicular to the actual spring direction, forces and movements can be absorbed in this direction without the actual spring movement being restricted or hindered thereby. This also eliminates the known noise developments and also prevents overloading of the holding means.

Die bevorzugte Ausgestaltung dieses Merkmals in Form einer federnden Zunge lässt sich vorteilhafterweise einfach und kostengünstig realisieren. Durch die bevorzugte Querschnittsform des Tragköpers lässt sich eine zuverlässige und einfach zu realisierende richtungsstabile Federwirkung erzielen. Ein derartiges erfindungsgemässes Federelement lässt sich auch einfach derart ausgestalten, dass es einfach an einem Grundkörper angebracht werden kann. Durch die bevorzugte Ausbildung des Haltemittels als Zapfen lässt sich das abzufedernde Bauteil einfach auf der Auflagefläche anbringen.The preferred embodiment of this feature in the form of a resilient tongue can advantageously be implemented simply and inexpensively. The preferred cross-sectional shape of the supporting body enables a reliable and easy-to-implement, directionally stable spring action to be achieved. Such a spring element according to the invention can also be easily configured in such a way that it can easily be attached to a base body. Due to the preferred design of the holding means as a pin, the component to be cushioned can be easily attached to the support surface.

Ein Ausführungsbeispiel der Erfindung wird nachstehend anhand von Zeichnungen noch naher erläutert. Es zeigen

  • Fig. 1 die Ansicht eines erfindungsgemässen Federelementes;
  • Fig. 2 den Längsschnitt durch das Federelement nach Fig. 1;
  • Fig. 3 die Ansicht eines Bettgestelles mit erfindungsgemässen Federelementen.
An embodiment of the invention is explained in more detail below with reference to drawings. Show it
  • 1 shows the view of a spring element according to the invention;
  • FIG. 2 shows the longitudinal section through the spring element according to FIG. 1;
  • Fig. 3 shows the view of a bed frame with spring elements according to the invention.

Figur 1 zeigt die Ansicht eines erfindungsgemässen Federelementes 1, bestehend aus einem Führungskörper 2 und darin federnd beweglichem Tragkörper 3.FIG. 1 shows the view of a spring element 1 according to the invention, consisting of a guide body 2 and a supporting body 3 which is resiliently movable therein.

Der Führungskörper 2 besteht hier beispielsweise aus einem einseitig offenen Hohlkörper mit rechteckigem Querschnitt. Der Führungskörper weist Befestigungsflanschen 4 auf, welche mit Bohrungen 5 zur Aufnahme von Befestigungsschrauben (nicht dargestellt) versehen sind. Über diese Flanschen kann das Federelement mit einem Grundkörper verbunden werden.The guide body 2 consists here, for example, of a hollow body with a rectangular cross section that is open on one side. The guide body has fastening flanges 4, which have holes 5 for receiving fastening screws (not shown) are provided. The spring element can be connected to a base body via these flanges.

Im Führungskörper 2 ist der Tragkörper 3 verschiebbar angeordnet, wobei das obere Ende des Tragkörpers 3 aus dem Führungskörper 2 herausragt. Dieses Ende des Tragkörpers 3 weist vorzugsweise einen nach oben gerichteten Zapfen 6 auf, welcher als Haltemittel für ein auf der Stirnfläche 3' des Tragkörpers 3 abzustützendes Bauteil dient.The support body 3 is arranged displaceably in the guide body 2, the upper end of the support body 3 protruding from the guide body 2. This end of the support body 3 preferably has an upwardly directed pin 6 which serves as a holding means for a component to be supported on the end face 3 'of the support body 3.

Der Tragkörper 3 ist mittels einer Feder 7 gegen den Boden des Führungskörpers 2 abgestützt, wie aus Figur 2 ersichtlich ist. Die Führung des Tragkörpers 3 im Führungskörper 2 wird durch dessen Seitenwände bewirkt. Damit ist eine federnde, tranlatorische Bewegung des Tragkörpers 3 im Führungskörper 2 realisiert.The support body 3 is supported by a spring 7 against the bottom of the guide body 2, as can be seen in Figure 2. The guide of the support body 3 in the guide body 2 is effected by the side walls. A resilient, translatory movement of the support body 3 in the guide body 2 is thus realized.

Für die Begrenzung des Federweges des Tragkörpers 3 nach oben, d.h. gegen die Öffnung des Führungskörpers 2 hin sind Begrenzungsmittel vorgesehen (nicht dargestellt). Diese Begrenzungsmittel können beispielsweise durch federnde Zungen mit in Öffnungen einrastbare Nocken gebildet sein.To limit the spring travel of the support body 3 upwards, i.e. limiting means are provided against the opening of the guide body 2 (not shown). These limiting means can be formed, for example, by resilient tongues with cams which can be latched into openings.

Im dargestellten Beispiel ist der Tragkörper bevorzugterweise aus einem kastenartigen Körper mit rechteckigem Querschnitt gebildet. Dabei wird eine Zunge 8 mittels eines durch die Stirnfläche 3' und eine Seitenfläche des Tragkörpers verlaufenden Schnittes 9 gebildet. Dadurch wird eine federnde Bewegung des Zapfens 6 senkrecht zur Achse des Führungskörpers 2 ermöglicht. Es ist selbstverständlich, dass der Tragkörper 2 dabei aus einem nicht vollständig steifen Material gefertigt ist, sondern aus einem wenigstens teilweise elastischen Material. Vorzugsweise besteht der Tragkörper aus Kunststoff.In the example shown, the support body is preferably formed from a box-like body with a rectangular cross section. In this case, a tongue 8 is formed by means of a cut 9 running through the end face 3 'and a side face of the support body. This enables a resilient movement of the pin 6 perpendicular to the axis of the guide body 2. It goes without saying that the support body 2 is made of a material that is not completely rigid, but of an at least partially elastic material. The support body is preferably made of plastic.

Als Beispiel einer Anwendung derartiger erfindungsgemässer Federelemente ist der in Figur 3 schematisch dargestellte Lattenrost für Betten zu betrachten. Beim dargestellten Lattenrost handelt es sich um einen Rahmen 10 mit darin federnd angeordneten Latten 11. Diese Latten sind als im wesentlichen steife Körper ausgebildet. Fur die Lagerung dieser Latten sind nun innen an den beiden längeren Seiten des Rahmens eine Anzahl der erfindungsgenmässen Federelemente 1 angeordnet. An den Lattenenden sind jeweils Bohrungen zur Aufnahme der Zapfen 6 der Federelemente 1 vorgesehen.The slatted frame for beds shown schematically in FIG. 3 is to be considered as an example of an application of such spring elements according to the invention. The slatted frame shown is a frame 10 with slats 11 resiliently arranged therein. These slats are designed as essentially rigid bodies. For the storage of these slats, a number of the spring elements 1 according to the invention are now arranged on the two longer sides of the frame. At the slat ends there are holes for receiving the pins 6 of the spring elements 1.

Die Lattenenden werden nun jeweils auf die Zapfen 6 der Federelemente 1 aufgesteckt und überspannen den freien Bereich des Rahmens 10 des nun gebildeten Lattenrostes. Wird nun eine dieser Latten 11 nur auf einer Seite des Rahmens 10 heruntergedrückt, so können die Zapfen 6 der Federelemente 1 diese Verdrehbewegung mitmachen. Dadurch wird eine Überlastung solcher fester Zapfen verhindert, welche bis zum Bruch des Zapfens führen kann, und gleichzeitig wird auch ein Verkanten des Tragkörpers 6 in der Führung 2 verhindert.The slat ends are now each attached to the pin 6 of the spring elements 1 and span the free area of the frame 10 of the slatted frame now formed. If one of these slats 11 is now pressed down only on one side of the frame 10, the pins 6 of the spring elements 1 can participate in this twisting movement. This prevents overloading of such fixed pins, which can lead to the pin breaking, and at the same time also prevents the supporting body 6 from tilting in the guide 2.
