Description
Stützvorrichtungen für schräg einstellbare Klappflächen an Liegemöbeln o. dgl., welche mittels Zahnstangen hochgestellt werden, sind bekannt. Die Zähne solcher Zahnstangen haben einseitige schräge Gleitflächen, damit bei Aufwärtsbewegung der Klappfläche die Zähne am Sperrstift entlanggleiten können. Will man die Klappfläche wieder abwärts bewegen, so muß die Zahnstange mit derSupport devices for obliquely adjustable folding surfaces on reclining furniture or the like, which are raised by means of toothed racks, are known. The teeth of such racks have oblique sliding surfaces on one side so that the teeth can slide along the locking pin when the hinged surface is moved upwards. If you want to move the folding surface downwards again, the rack with the
ίο Hand oder einem Hilfsmittel vom Sperrstift so weit entfernt werden, daß die Zähne den Stift nicht mehr berühren. Eine solche unvollkommene Einrichtung wird durch die Erfindung beseitigt und eine Stützvorrichtung geschaffen, welche sich beim Aufwärts- wie Abwärtsbewegen der Klappfläche ohne Hilfsmittel in beliebiger Höhe selbsttätig einstellt. Die Erfindung besteht darin, daß jeder Zahn der Zahnstange begrenzt ist durch eine den Stift aufnehmende Rast und eine sich an diese nach unten anschließende schräge Gleitfläche und daß die sich von der untersten Rast nach unten fortsetzende schräge Gleitfläche in eine hakenartige Auskerbung übergeht, derart, daß nach dem Anheben der Zahnstange bis zum Eingreifen des Stiftes in die Auskerbung bei schneller Abwärtsbewegung die Zähne den Stift von einer zur anderen Schrägfläche überspringen, ohne daß die dazwischenliegenden Rasten mit dem Stift in Eingriff kommen.ίο Hand or a tool from the locking pin removed so far that the teeth no longer touch the post. Such an imperfect Means is eliminated by the invention and a support device is provided, which when upward as Moving the folding surface downwards automatically at any height without tools. The invention consists in that each tooth of the rack is limited by a detent and detent receiving the pin a sloping sliding surface adjoining this downward and that the from the bottom detent downward sloping sliding surface into a hook-like notch passes, in such a way that after lifting the rack until the engagement of the pin in the notch with rapid downward movement the teeth skip the pin from one inclined surface to the other without the intervening notches with the Pin come into engagement.

An der Klappfläche ι ist eine Zahnstange 2 durch einen Bolzen 3 angelenkt. An dem fest· stehenden Teil 4 ist der übliche Sperrstift 5 vorgesehen. Bei Aufwärtsbewegung und höchster Einstellung der Klappfläche 1 gleiten die schrägen Flächen 7 an dem Stift entlang, bis dieser die letzte Rast 6 erreicht hat. Soll die Klappfläche wieder in ihre alte Lage gebracht werden, so wird sie ein wenig aufwärts bewegt, wonach der Stift 5 aus dem letzten Rast in eine hakenartige Auskerbung 8 übergeht.A toothed rack 2 is hinged to the folding surface ι by a bolt 3. At the feast standing part 4, the usual locking pin 5 is provided. With upward movement and highest setting of the folding surface 1, the inclined surfaces 7 slide along the pin, until it has reached the last stop 6. Should the folding surface be brought back to its old position it is moved upwards a little, after which the pin 5 from the last detent into a hook-like notch 8 transforms.
Bei schnellem Abwärtsbewegen der Klappfläche ι gleiten die schrägen Flächen 7 an dem Stift 5 entlang, ohne daß der Stift in die Rasten 6 eingreift.When the folding surface ι moves down rapidly, the inclined surfaces 7 slide along the pin 5 without the pin engaging the notches 6.
