Description
Zugvorrichtung für Ausziehtische Die Erfindung betrifft eine Verbesserung der Zugvorrichtung für Ausziehtische mit selbsttätig wirkender Spannvorrichtung nach dem Patent 668 59q.. Bei dieser nimmt das Einhängen der aus zwei Zugbändern bestehenden Zugmittel viel Zeit in Anspruch.Pulling Device for Extending Tables The invention relates to an improvement the pulling device for extending tables with an automatically acting clamping device according to the patent 668 59q .. With this one takes the hanging of two drawstrings existing traction devices take up a lot of time.
Dieser Nachteil wird gemäß der Erfindung dadurch behoben, daß in endlose Zugseile Spannvorrichtungen eingeschaltet sind, die aus eine Schraubenfeder aufnehmenden Hülsen oder aus Rollen mit eingebauter Spiralfeder bestehen und mittels eines Querstifts bzw. Drehzapfens mit der jeweiligen Ausziehleiste einsteckbar verbunden sind. Hierdurch werden die Spannvorrichtungen beim Lösen von den Führungsleisten einfach nach .unten gedrückt, wodurch sich die Stifte von den Leisten lösen. Die endlosen Seilzüge bleiben unter Spannung geschlossen und beim Einbau werden die Stifte wieder in die Bohrungen der Leisten gesteckt und der Zug ist in Ordnung. In der Zeichnung ist der Erfindungsgegenstand in einem Ausführungsbeispiel dargestellt.This disadvantage is eliminated according to the invention in that in endless Pull ropes tensioning devices are switched on, which consist of a helical spring receiving Sleeves or rollers with a built-in spiral spring and by means of a cross pin or pivot pin are pluggably connected to the respective pull-out strip. Through this the clamping devices simply move downwards when loosening the guide rails which causes the pins to loosen from the bars. The endless cables remain closed under tension and when installing the pins are back in the holes the bar is plugged in and the train is fine. The subject of the invention is shown in the drawing shown in one embodiment.
Fig. i zeigt die Spannvorrichtung im Schnitt, Fig. z diese in eingebautem Zustande am Tisch, und Fig. 3 zeigt eine Ausführung mit Rolle und eingebauter Spiralfeder.Fig. I shows the clamping device in section, Fig. Z shows it in built-in Conditions at the table, and Fig. 3 shows an embodiment with a roller and built-in spiral spring.
Die Spannvorrichtung ist in endlose Zugmittel d eingeschaltet und besteht aus der Hülse a (Fig. i) und der in ihr 'lagernden Schraubenfeder b oder aus der Rolle k (Fig. 3) mit eingebauter Spiralfeder L. Sie wird mittels des Querstifts e (Fig. i) bzw. des Drehzapfens h (Fig.3) mit der jeweiligen Ausziehleiste eins.teckbar verbunden. Die Seilteile sind mit einem ihrer Enden an den Hülsen a (Fig. i) durch den Querstift e und mit den anderen Enden mit den in den Hülsen a geführten Kolbenscheiben c befestigt, welche die Schraubenfeder b gegen den Hülsenboden drückt, oder aber mit einem der Enden an den Rollen k (Fig. 3 ), mit den anderen Enden mit den auf dem Drehzapfen n sitzenden Bügeln o. Die Rollen k sind mit Sperrzähnen rn (Fig. 3) versehen, in welchen die als Sperrfeder ausgebildete - Blattfeder p rastet, welche an der Ausziehleiste. g, am Bügel o oder am Drehzapfen n befestigt sein kann.The tensioning device is switched on in endless traction means d and consists of the sleeve a (Fig. I) and the coil spring b mounted in it or of the roller k (Fig. 3) with built-in coil spring L. It is opened by means of the cross pin e (Fig . i) or the pivot h (Fig. 3) connected to the respective pull-out strip in a pluggable manner. The cable parts are attached with one of their ends to the sleeves a (Fig. I) by the cross pin e and with the other ends to the piston discs c guided in the sleeves a, which presses the coil spring b against the sleeve base, or with one of the Ends on the rollers k (Fig. 3), with the other ends with the brackets o sitting on the pivot n. The rollers k are provided with ratchet teeth rn (Fig. 3), in which the leaf spring p, designed as a locking spring, engages, which on the pull-out bar. g, can be attached to the bracket o or to the pivot n.
