Description

Der Erfindung, die ein Welldrahtfederpolster mit nachgiebiger Kante betrifft, liegt die Überlegung zugrunde, daß die' bekannten .Welldrahtfedern bei der Belastung ihre Länge zu ändern bestrebt sind und deshalb bekannt-. lieh zu Polsterzwecken an beiden Enden festzulegen sind. Die beim Be- oder Entlasten nötige Längenveränderung wird durch Zusammenpressen oder Entspannen der Windüngen ausgeglichen, ohne daß die Entfernung der beiden Federenden dabei selbst einer Veränderung unterliegt. Auf dieser Erkenntnis aufbauend, sind die Enden der Welldrahtfedern eines Flachpolsters mit nachgiebiger Kante erfindungsgemäß ein- oder beiderseits an einer gemeinsamen Leiste o. dgl. festgelegt, die entgegen der Belastungsrichtung federnd abgestützt ist. Es bedarf somit nicht mehr jede Welldrahtfeder, wie für Flachfedern bekannt, einer gesonderten Abstützfeder. Es genügen beispielsweise zwei bis drei Abstützfedern, die an den beiden Enden der Stützleiste o. dgl. wirksam werden, was insbesondere bei breiten Polstern eine große Ersparnis zur Folge hat. Hierzu kommt noch, daß die Enden der Welldrahtfedern des Polsters auf diese Weise eine einwandfreie, gegen Verdrehung gesicherte Festlegung erfahren, was namentlich dann als vorteilhaft ins Auge fällt, wenn die nachgiebige Kante des Polsters nur an einer Stelle belastet wird. Die nachgiebige Kante wird dann in ihrer Gesamtheit niedergedrückt. Sind die Polsterfedern aber jede mit einer gesonderten Abstützfeder ausgestattet, so wird die nachgiebige Kante des Polsters in nach unten gerichteter Wölbung durchgebogen, was zur Folge hat, daß die Enden der Polsterfedern sich der Form dieses Bogens entsprechend verdrehen· müssen! Die Polsterfüllung wird dadurch verhältnismäßig schnell beschädigt.The invention relating to a resilient edge corrugated wire spring pad resides based on the idea that the 'well-known. Wavy wire springs their length when loaded strive to change and are therefore known-. loaned to be fixed at both ends for upholstery purposes are. The change in length required when loading or unloading is achieved by pressing together or relaxing the windings balanced without affecting the distance the two spring ends themselves are subject to change. On this realization building up, the ends of the corrugated wire springs of a flat cushion are more resilient Edge according to the invention on one or both sides on a common bar or the like. set, which is resiliently supported counter to the loading direction. So it takes no longer every corrugated wire spring, as known for flat springs, a separate support spring. For example, two to three support springs that are effective at the two ends of the support strip or the like are sufficient, which results in great savings, especially with wide cushions. To this comes nor that the ends of the corrugated wire springs of the cushion in this way a perfect, Find out what is specifically advantageous against twisting is eye-catching when the resilient edge of the cushion is only loaded in one place. The compliant edge is then depressed in its entirety. Are the upholstery springs but each is equipped with a separate support spring, so the yielding one becomes The edge of the cushion is bent in a downward curvature, with the result that the ends of the cushion springs must twist according to the shape of this arch! The padding will be thereby damaged relatively quickly.

Die Zeichnung stellt ein Ausführungsbeispiel der Erfindung im Schaubild dar.The drawing shows an embodiment of the invention in the diagram.

Die Enden. der .Welldrahtfedern 1, von denen der Übersicht halber nur eine in ihrer ganzen Länge dargestellt ist, sind ein- oder auch beiderseits an einer gemeinsamen, über dem Gestell 2 Hegenden Leiste 3 o. dgl. festgelegt, und diese Leiste 3 ist entgegen der Belastungsrichtung federnd abgestützt.The ends. the .wave wire springs 1, from for the sake of clarity, only one is shown in its entire length, are one or also fixed on both sides on a common bar 3 or the like hanging over the frame 2, and this bar 3 is resiliently supported counter to the loading direction.

Bei dem dargestellten Beispiel erfolgt dabei die federnde Abstützung der Leiste 3 o. dgl. vermittels Blattfedern 4, die am unteren Ende am Gestell 2 und am oberen Ende an den Enden der Leiste 3 befestigt sind. Es steht aber auch nichts im Wege, sich einer Schrauben- oder Schenkelfederabstützung dieser Leiste 3 zu bedienen.In the example shown, the resilient support of the bar 3 takes place o. The like. By means of leaf springs 4, which are at the lower end on the frame 2 and at the upper end are attached to the ends of the bar 3. But nothing stands in the way of yourself a helical or torsion spring support of this bar 3 to use.
