Description
Die Erfindung betrifft eine aus einem Gewebe bestehende Liege- oder Sitzfläche für Matratzen bzw. Sessel, die an der Einknickstelle durch Federn in die gewünschte Form gezogen wird. Das Neue besteht darin, daß an dieser Stelle unterhalb eines Stahlbandes mit den Stirnflächen aneinanderstoßende Klötzchen angebracht sind und die Zugfedern an den freien Enden der beiden äußersten ίο Klötzchen angreifen. Durch diese Anordnung wird erreicht,, daß, obwohl nur zwei Federn, und zwar an den Kanten des Gewebes vorgesehen sind, eine Wölbung der Liege- oder Sitzfläche an der Knickstelle vermieden, dagegen die nachgiebige Durchbiegung bei Belastung nicht verhindert wird.The invention relates to a fabric lying or sitting surface for Mattresses or armchairs that spring into the desired shape at the point of inflection is pulled. The new thing is that at this point below a steel band with the end faces abutting blocks are attached and the tension springs Attack the free ends of the two outermost ίο blocks. Through this arrangement it is achieved, that, although only two springs, are provided on the edges of the fabric are, a curvature of the lying or sitting surface at the kink avoided, however the resilient deflection under load is not prevented.
Auf der Zeichnung ist die Erfindung an einer Matratze beispielsweise dargestellt, und zwar zeigtIn the drawing, the invention is shown on a mattress, for example, and although shows
ao Fig. ι einen Längsschnitt,
Fig. 2 einen Querschnitt.
Das Gewebe g ist in bekannter Weise mit den Enden durch Leisten α, & am Matratzenrahmen
befestigt. An der Knickstelle der Liegefläche befindet sich ein Stahlband s, unter
dem, und zwar an der Unterseite des Gewebes, Klötzchen h angebracht sind, die mit
den Stirnflächen aneinanderstoßen. An den freien Enden der beiden äußersten Klötzchen
greifen die Zugfedern d an, deren Spannung
durch die Muttern e geregelt werden kann. Die Klötzchen wirken der Durchbiegung nach
oben wie ein einziger starrer Stab entgegen, während sie bei Belastung der Liegefläche an
den Stoßstellen keilartig auseinanderklaffen.ao Fig. ι a longitudinal section,
Fig. 2 is a cross section.
The ends of the fabric g are fastened to the mattress frame by strips α, & in a known manner. At the kink of the bed surface there is a steel band s, under which, on the underside of the fabric, blocks h are attached, the end faces of which meet. The tension springs d attack the free ends of the two outermost blocks, the tension of which can be regulated by the nuts e. The blocks counteract the upward deflection like a single rigid rod, while when the lying surface is loaded, they gape apart like a wedge at the joints.
