Description

Die vorliegende Erfindung betrifft eine Vorrichtung zur variablen Verstärkung der elastischen Abstützkräfte in beliebigen Partialbereichen eines Liegemöbel-Lattenrosts mit quer zu dessen Längsachse ausgerichteten, je endseitig an Längszargen gelagerten Federleisten, umfassend zumindest zwischen zwei benachbarten Federleisten im wesentlichen in Richtung der Längsachse anbringbare elastische Kupplungselemente, welche den jeweiligen Leistenabstand überbrücken (DE-B-2 756 477).The present invention relates to a device for variable reinforcement of the elastic support forces in any partial areas of a reclining furniture slatted frame with spring bars oriented transversely to its longitudinal axis and each with spring bars mounted at the end on longitudinal frames, comprising at least between two adjacent spring bars which can be attached essentially in the direction of the longitudinal axis, which coupling elements bridge the respective bar spacing (DE-B-2 756 477).

Die bekannten, mit quer verlaufenden Federleisten versehenen Liegemöbel, welche auch als Lättlicouch bezeichnet werden, weisen eine elastisch verformbare Liegefläche auf, die sich je nach der lokalen Belastung durchbiegt und die Belastung mit einer entsprechnden, der Belastung entgegengerichteten Abstützkraft abfängt. Diese elastische Reaktionsfähigkeit der Liegefläche, die zuweilen auch als Federhärte bezeichnet wird, ist nun bei den bekannten Liegemöbeln auf der gesamten Liegefläche gleich gross, obwohl die Belastung der Liegefläche zweifellos lokal sehr unterschiedlich ist. So muss einerseits berücksichtigt werden, das die grösste Belastung im allgemeinen etwa im Mittelbereich der Liegefläche, d. h. an den Abstützstellen von Gesäss und Hüfte, auftritt, während die Endbereiche zur Abstütztellen von Kopf und Füssen kaum nennenswerten Belastungen unterworfen sind. Hinzu kommt, dass der Mensch im Laufe der Zeit sein Körpergewicht ganz erheblich zu verändern vermag und dass die Belastungsverhältnisse eines Bettes beispielsweise nach einer Abmagerungskur oder während einer Schwangerschaft beträchtlichen Schwankungen unterworfen sind.The known reclining furniture provided with transverse spring slats, which are also referred to as Lättlicouch, have an elastically deformable lying surface that bends depending on the local load and intercepts the load with a corresponding support force opposing the load. This elastic reactivity of the lying surface, which is sometimes also referred to as spring hardness, is now the same size in the known lying furniture over the entire lying surface, although the load on the lying surface is undoubtedly very different locally. On the one hand, it must be taken into account that the greatest load is generally in the central area of the bed, i.e. H. at the buttocks and hip support points, while the end areas for supporting the head and feet are hardly subjected to any noteworthy loads. In addition, people can change their body weight considerably over time and that the load conditions of a bed are subject to considerable fluctuations, for example after an emaciation regimen or during pregnancy.

Es ist somit die Aufgabe der vorliegenden Erfindung, eine Vorrichtung zur Zonenverstärkung an Liegemöbeln mit Federleisten zu schaffen, die es gestattet, beliebige Zonen der Liegefläche, insbesondere aber die meistbelastete Mittelzone, nach Belieben bezüglich ihrer elastischen Abstützkraft zu variieren, um sie somit den gerade herrschenden Belastungsverhältnissen im Sinne physiologisch richtigen Liegens anpassen zu können. Die Vorrichtung soll ferner zu ihrer Befestigung keinerlei Beschädigung der angrenzenden Federleisten erfordern und im übrigen den zusätzlichen Vorteil mit sich bringen, dass sie zur Schonung der Obermatratze und deren besserem Tragverhalten beiträgt.It is therefore the object of the present invention to provide a device for zone reinforcement on reclining furniture with spring slats, which allows any zones of the lying surface, but in particular the most stressed middle zone, to be varied at will with regard to their elastic supporting force, in order to thus prevail To be able to adjust stress conditions in the sense of physiologically correct lying. The device should also require no damage to the adjacent spring slats for its attachment and also bring with it the additional advantage that it contributes to the protection of the top mattress and its better carrying behavior.

Diese Aufgabe wird dank der im Kennzeichen des unabhängigen Anspruchs 1 definierten Merkmalskombination gelöst. Ausführungsvarianten des Erfindungsgegenstandes in den abhängigen Ansprüchen definiert.This object is achieved thanks to the combination of features defined in the characterizing part of independent claim 1. Variants of the subject matter of the invention defined in the dependent claims.

Nachstehend wird anhand der beiliegenden Zeichnung ein Ausführungsbeispiel des Erfindungsgegenstandes beschrieben.An exemplary embodiment of the subject matter of the invention is described below with reference to the accompanying drawing.

  • Figur 1 ist eine Draufsicht auf einen für ein Liegemöbel bestimmten Lattenrost,FIG. 1 is a top view of a slatted frame intended for reclining furniture,
  • Figur 2 ist eine Perspektivansicht eines der elastischen Kupplungselemente,FIG. 2 is a perspective view of one of the elastic coupling elements,
  • Figur 3 zeigt das montierte Kupplungselement in Seitenansicht undFigure 3 shows the assembled coupling element in side view and
  • Figur 4 ist ein Schnitt längs der Linie IV-IV aus Fig. 3.FIG. 4 is a section along the line IV-IV from FIG. 3.

Fig. 1 zeigt einen in seiner Gesamtheit mit 1 bezeichneten Lattenrost, welcher sich aus zwei Längszargen 2 und einer Anzahl quer verlaufender Federleisten 3 zusammensetzt. Die Federleisten 3 sind in bekannter Weise als mehrschichtige Holzfedern ausgebildet und stützen sich auf gummielastische Stützkörper 4, die an den Innenflächen der Längszargen 2 verankert sind. Auf je einem Paar dieser Stützkörper 4 ruhen, wie die Figur zeigt, zwei in gegenseitigem Abstand angeordnete Federleisten 3, die somit paarweise den Stützkörpern zugeordnet sind. Einzelheiten dieser Konstruktion ergeben sich aus der CH-A-619 605.Fig. 1 shows a slatted frame designated in its entirety with 1, which is composed of two longitudinal frames 2 and a number of transverse spring slats 3. The female connectors 3 are designed in a known manner as multi-layer wooden springs and are based on rubber-elastic support bodies 4, which are anchored to the inner surfaces of the longitudinal frames 2. On each pair of these support bodies 4, as the figure shows, there are two spring strips 3 which are arranged at a mutual distance and are thus assigned to the support bodies in pairs. Details of this construction can be found in CH-A-619 605.

Ein bekannter Mittelgurt M ist im Mittelbereich des Lattenrostes angeordnet.A known central belt M is arranged in the central region of the slatted frame.

Die einander benachbarten Federleistenpaare 3 befinden sich in gegenseitigem Abstand a. Dieser Abstand muss bei Holzfederrosten relativ gross gewählt werden, da sich bei zu enger Teilung eine aussergewöhnlich hohe Federhärte ergäbe. Aufgrund des grossen Abstandes a besthet jedoch das Risiko, dass die nicht dargestellte Obermatratze mit ihrer Unterseite in den Zwischenraum zwischen einander benachbarten Federleistenpaaren eingedrückt wird und dort unter dem Einfluss der Schlafbewegungen frühzeitig abgenutzt bzw. beschädigt wird. Die Behebung dieses Mangels ist eine der Aufgaben, die durch die vorliegende Erfindung gelöst werden sollen.The mutually adjacent pairs of female connectors 3 are at a mutual distance a. This distance must be chosen to be relatively large for wooden spring gratings, because if the pitch is too narrow, the spring hardness would be exceptionally high. However, due to the large distance a, there is a risk that the underside of the top mattress, not shown, will be pressed into the space between adjacent pairs of spring slats, where it will be worn or damaged prematurely under the influence of sleep movements. Correcting this deficiency is one of the objects that the present invention is intended to solve.

In einem mit B bezeichneten Belastungsbereich des Lattenrostes, in welchem erfahrungsgemäss die grössten statischen und dynamischen Belastungen auftreten, sind in den Zwischenräumen zweier benachbarter .Federleistenpaare 3 Vorrichtungen angeordnet, welche es nicht nur gestatten, diese Zwischenräume unter weitgehender Schonung der Obermatratze zu überbrücken, sondern die eine gezielte, in bezug auf lokale Verteilung und Intensität der Federhärte variable Anpassung der elastischen Abstützbedingungen an bestimmte Bedarfsfälle zulassen. Diese Vorrichtung umfasst in jedem der genannten Zwischenräume zwei gummielastische Kupplungselemente 5 sowie eine Zusatzfederlatte Z.In a load area of the slatted frame designated by B, in which experience has shown that the greatest static and dynamic loads occur, 3 devices are arranged in the spaces between two adjacent pairs of spring slats, which not only allow these spaces to be bridged while largely protecting the top mattress, but also the Allow a targeted adjustment of the elastic support conditions to specific needs in relation to the local distribution and intensity of the spring hardness. In each of the spaces mentioned, this device comprises two rubber-elastic coupling elements 5 and an additional spring slat Z.

Wie Fig. 2 zeigt, ist das Kupplungselement 5 ein Profilkörper, welcher zwei Längsleisten 6/7 aufweist, die durch Querstege 8, 9 miteinander verbunden sind. Auf diese Weise ergibt sich im Mittelbereich eine Durchgangsöffnung 10 und an den beiden Enden je eine offene Ausnehmung 11/12. Die Höhe h dieser Ausnehmungen entspricht in etwa der Dicke der Holzfederlatten 3 (Fig. 3), so dass sich das Kupplungselement 5 nach Art einer Brücke zwischen zwei Holzfederleistenpaaren 3 anordnen und mit den Ausnehmungen 11, 12 an den angrenzenden Holzfederleisten sichern lässt. Im Hinblick auf eine einfache Handhabung beim Ein- und Ausbau sind die beiden die Ausnehmungen begrenzenden Haltestege 13 und 14 (Fig. 3) von unterschiedlicher Länge (vergleiche Längendifferenz d in Fig. 3), in jedem Falle aber kürzer als die Gesamtbreite einer Federleiste 3. Bei der Montage kann man somit beispielsweise die Ausnehmung 11 über eine Holzfederleiste stecken und das Kupplungselement dann von oben her mit der kürzeren Stege 14 über die andere Holzfederleiste schnappen lassen. Das Kupplungselement, das aus einem zähen, gummielastischen Werkstoff hoher Biegefestigkeit bestehen sollte, ist damit sicher im Zwischenraum zwischen zwei Holzfederleistenpaaren verankert.As FIG. 2 shows, the coupling element 5 is a profile body which has two longitudinal strips 6/7 which are connected to one another by transverse webs 8, 9. In this way, there is a through opening 10 in the central region and an open recess 11/12 at each of the two ends. The height h of these recesses corresponds approximately to the thickness of the wooden spring slats 3 (FIG. 3), so that the coupling element 5 is arranged in the manner of a bridge between two pairs of wooden spring slats 3 and with the off Secures 11, 12 can be secured to the adjacent wooden slats. With a view to simple handling during installation and removal, the two retaining webs 13 and 14 (FIG. 3) delimiting the recesses are of different lengths (compare length difference d in FIG. 3), but in any case shorter than the overall width of a female connector 3 During assembly, it is thus possible, for example, to insert the recess 11 over a wooden spring strip and then to snap the coupling element from above with the shorter webs 14 over the other wooden spring strip. The coupling element, which should consist of a tough, rubber-elastic material with high flexural strength, is thus securely anchored in the space between two pairs of wooden slats.

Die Durchgangsöffnung 10 ist so bemessen, dass sich die in Fig. 1 mit Z bezeichnete Zusatzfederlatte knapp durch die Oeffnung hindurchstecken lässt und dann satt in derselben gehalten ist. Vorzugsweise sind die Innenwände der Durchgangsöffnung 10 nach einer Seite oder nach beiden Seiten leicht verengt, wie dies insbesondere Fig. 4 zeigt. Die Stege 8 und 9 sind bei dem Ausführungspeispiel an den Anlageflächen F an der Zusatzfederlatte Z leicht bombiert.The through opening 10 is dimensioned such that the additional spring slat designated Z in FIG. 1 can be pushed through the opening and is then held firmly in the same. The inner walls of the through opening 10 are preferably narrowed slightly on one side or on both sides, as is shown in particular in FIG. 4. The webs 8 and 9 are slightly cambered on the contact surfaces F on the additional spring slat Z in the exemplary embodiment.

Bei der Anordnung nach Fig. 1 sind vier Zusatzfederlatten Z mittels vier Paaren von Kupplungselementen 5 vorgesehen. Der gegenseitige Abstand c der Kupplungselemente 5 lässt sich leicht varrieren, was ebenfalls einen Einfluss auf das elastische Abstützverhalten der betreffenden Zusatzfederleiste Z ausübt.In the arrangement according to FIG. 1, four additional spring slats Z are provided by means of four pairs of coupling elements 5. The mutual distance c of the coupling elements 5 can be varied slightly, which likewise exerts an influence on the elastic support behavior of the additional spring strip Z in question.

In der praktischen Anwendung der beschriebenen Vorrichtung wird man demgemäss in dem Bereich stärkster Belastung eine beliebige Anzahl von Zusatzfederlatten Z anbringen und deren elastisches Verhalten durch Regulieren des Abstandes c den individuellen Bedürfnissen anpassen. Da die Zusatzfederlatten Z über die Kupplungselemente 5 an den Federleisten 3 verankert sind, werden sich auch die Federungseigenschaften der letzteren verändern. Somit lässt sich der gesamte Abstützbereich B (Fig. 1) « verhärten », während innerhalb dieses Bereiches wiederum einzelne Stellen entweder besonders hart oder nachgiebiger gestaltet werden können.In the practical application of the device described, any number of additional spring slats Z will accordingly be attached in the area of the heaviest load and their elastic behavior will be adapted to individual needs by regulating the distance c. Since the additional spring slats Z are anchored to the spring strips 3 via the coupling elements 5, the suspension properties of the latter will also change. The entire support area B (FIG. 1) can thus be “hardened”, while individual areas within this area can either be made particularly hard or more flexible.

Gerade in diesem Belastungsbereich B ist es auch besonders wichtig, dass die Obermatratze nicht in die Zwischenräume zwischen zwei Federleistenpaaren 3 gepresst und dort beschädigt werden kann. Dies wird durch die Anordnung der Zusatzfederlatten wirksam verhindert. Eine auf der Oberfläche der Kupplungselemente 5 angeordnete Profilierung P (Fig. 2) verhindert das unerwünschte Verrutschen der Obermatratze sowie die Ansammlung von Feuchtigkeit.Especially in this load area B, it is particularly important that the top mattress cannot be pressed into the spaces between two pairs of female connectors 3 and damaged there. This is effectively prevented by the arrangement of the additional spring slats. A profiling P (FIG. 2) arranged on the surface of the coupling elements 5 prevents the top mattress from slipping and the accumulation of moisture.

Der im vorliegenden Zusammenhang verwendete Ausdruck « gummielastisch » ist so zu verstehen, dass er sämtliche Materialien, insbesondere auch Kunststoffe umfasst, die sich aufgrund ihres Elastizitätsverhaltens mit dem Gummi vergleichen lassen. Der auf dem Werkstoff selbst beruhenden Gummielastizität steht somit die Formelastizität, z. B. einer Schraubenfeder, gegenüber.The term “rubber-elastic” used in the present context is to be understood to include all materials, in particular also plastics, which can be compared to rubber due to their elasticity behavior. The rubber elasticity based on the material itself is the formula elasticity, z. B. a coil spring opposite.
