Description
Bei - den bekannten - Drehstühlen erfolgt die Höhenverstellung des Sitzes dadurch, däß eine Stellschraube gelöst und nach Verstellung wieder angezogen wird. Stühle derartiger Konstruktion hab-en den Nachteil, daß die Höhenverstellung ziemlich umständlich ist -und vielfach nur unter Benutzung eines Werkzeuges bewerkstelligt werden kann. Die Erfindung hat eine Vorrichtung zum Gegenstand, die diese Nachteile vermeidet. In den Abb. i biss 3 ist eine .derartige Vorrichtung dargestellt. An dem eigentlichen Untergestell des Stuhles sind die .drei Stützrohre 5 mit einem Führungsrohr z verbunden, in welchem die Welle i des Stuhlsitzes 6 drehbar geführt ist. In Odem Führungsrohr .befinden sich Bohrungen 7; in welche Kugeln 3 eingeführt werden. Der obere Teil einer Muffe 4 drückt die Kugeln 3 in die eingedrehten Kerben 8, so idaß die Welle mit :dem Sitz in ihrer Höhenlage arretiert isst. Soll nun eine Höhenverstellung vorgenommen werden, so wird -die Muffe 4 in die Höhegeschoben, so daß idie Kugeln 3 in den erweiterten Teil 9 der Muffe q: fallen und die Welle i in. der Höhe beliebig verstellt werden kann. Nach Einstellung der Welle i auf die gewünschte Hrihe wird die Muffe q. wieder nach unten geschoben, so daß die Kugeln 3 in die Kerbe entsprechend der veränderten Höhe geschoben werden. Damit ist der Stuhlsitz in seiner neuen Höhenlage -arretiert. Die Verstellung auf diese Art und Weise ist sehr einfach, -und es sind vor allen Dingen keinerlei Werkzeuge zu ihrer Handhabung erforderlich. Abb. 2 zeigt,die Vorrichtung während,der Verstellung, d. h. die Kugeln gleiten von einer Kerbe 8 in die andere. A.bb. 3 zeigt einen drehbaren Stuhl gemäß dem Erfindungsgegenstand in .seiner ganzen Ansicht.In the case of the known swivel chairs, the height of the seat is adjusted by loosening an adjusting screw and tightening it again after adjustment. Chairs of this type have the disadvantage that the height adjustment is rather cumbersome and in many cases can only be done using a tool. The subject of the invention is a device which avoids these disadvantages. Such a device is shown in Figs. 1 to 3. On the actual underframe of the chair, the three support tubes 5 are connected to a guide tube z in which the shaft i of the chair seat 6 is rotatably guided. In the guide tube there are holes 7; in which balls 3 are inserted. The upper part of a sleeve 4 presses the balls 3 into the screwed-in notches 8, so that the shaft eats with the seat locked in its height position. If a height adjustment is now to be made, the sleeve 4 is pushed upwards so that the balls 3 fall into the enlarged part 9 of the sleeve q: and the height of the shaft i can be adjusted as desired. After adjusting the shaft i to the required height, the sleeve q. pushed back down so that the balls 3 are pushed into the notch according to the changed height. The chair seat is now locked in its new height position. The adjustment in this way is very simple and, above all, no tools are required to handle it. Fig. 2 shows the device during, the adjustment, i. H. the balls slide from one notch 8 into the other. A.bb. 3 shows a rotatable chair according to the subject matter of the invention in its whole view.
