Description

Die Erfindung betrifft eine Stützvorrichtung für schräg einstellbare Klappflächen, insbesondere für Kopf- und Rückenstützen von Polstermöbeln, Matratzen, Eisenbetten, u. dgl., bestehend aus einer auf einem Sperrstift gleitenden Stützstange, die nach Art einer Zahnstange mit Einkerbungen versehen ist. Gemäß der Erfindung sind unterhalb der Einkerbungen Sperrscheiben drehbar und in ίο ihrer Drehung derart begrenzt befestigt, daß sie eine Auf- oder Abwärtsbewegung ausführen können.The invention relates to a support device for inclined adjustable folding surfaces, in particular for head and backrests of upholstered furniture, mattresses, iron beds, etc., consisting of a sliding on a locking pin Support rod which is provided with notches in the manner of a toothed rack. According to the invention are below the Notches locking disks rotatable and fixed in ίο their rotation limited in such a way that they can move up or down.

In der Zeichnung ist der Erfindungsgegenstand beispielsweise in Seitenansicht dargestellt, und zwar zeigtIn the drawing, the subject matter of the invention is shown, for example, in a side view, namely shows

Abb. ι die Stellung, in der der Stift die letzte Auskerbung erreicht hat,Fig. Ι the position in which the pin has reached the last notch,

Abb. 2 die Stellung, in der der Stift zwischen einem beweglichen Sperrmittel und der vorstehenden Endsperrung landet, undFig. 2 the position in which the pin between a movable locking means and the above final lock lands, and

Abb. 3 die Überführung des Stiftes über die an der Stützstange befindlichen Auskerbungen. Fig. 3 the transfer of the pin over the notches on the support rod.

Die Klappfläche 1 ist mit einer Stützstange 2 versehen, die durch einen Bolzen 4 an der Klappfläche 1 angelenkt und, wie bekannt, mit Auskerbungen 5 versehen ist, mit denen die Stange auf einem Stift 6 abgestützt werden kann. Unterhalb der Auskerbungen 5 sind bewegliche Sperrscheiben 3 vorgesehen, welche derart drehbefestigt sind, daß sie eine Aufwärts- oder -Abwärtsbewegung machen können.The folding surface 1 is provided with a support rod 2, which is secured by a bolt 4 hinged to the folding surface 1 and, as is known, is provided with notches 5, with which the rod can be supported on a pin 6. Below the notches 5 Movable locking disks 3 are provided, which are rotatably mounted so that they a Be able to make an upward or downward movement.

Wie aus Abb. 1 ersichtlich ist, halten die Sperrscheiben 3 durch ihr Gewicht herabhängend die Auskerbungen 5 offen, so daß bei Aufwärtsbewegung der Klappfläche 1 der Stift 6 sich ungehindert in jede Auskerbung 5 festsetzen kann. Die Stützstange kann aus Winkeleisen hergestellt sein, so daß sie knickfest ist und ihr rückwärtiger Schenkel zur Begrenzung der Drehbewegung der Sperrsoheiben benutzt werden kann.As can be seen from Fig. 1, the locking disks 3 keep hanging due to their weight the notches 5 open, so that when the folding surface 1 moves upward, the Pin 6 can fix itself unhindered in each notch 5. The support rod can be made of angle iron, so that it is kink-proof and its rear leg to limit the rotational movement of the Lock washers can be used.

Will man die Klappfläche 1 aus der höchsten Stellung abwärts bewegen, so hebt man sie an, bis der Stift 6 über die letzte Sperrscheibe gleitet. Beim Herunterlassen der Klappfläche 1 gleitet die Stützstange 2 auf den Sperrscheiben 3 über den Stift 6 hinweg. Unter dem Gewicht der Stützstange 2 werden die Sperrscheiben aufwärts gedreht und schließen die Auskerbungen 5 ab, so daß sich der Stift 6 nicht in den Auskerbungen festsetzen kann. Ist der Stift 6 jeweils über die Sperrscheibe hinweggelangt, so fällt sie in ihre Hängelage zurüde, wodurch bei der Aufwärtsbewegung der Klappfläche der Stift 6 sich ungehindert in den Auskerbungen 5 festsetzen kann.If you want to move the folding surface 1 down from the highest position, you lift until the pin 6 slides over the last locking disc. When lowering the Hinged surface 1, the support rod 2 slides on the locking disks 3 over the pin 6. Under the weight of the support rod 2, the locking disks are rotated upwards and close the notches 5 so that the pin 6 does not get stuck in the notches can. If the pin 6 has passed over the locking disk, it falls into their hanging position backwards, whereby the pin 6 can get stuck in the notches 5 unhindered.
