Description

Vorrichtung zum Verstellen der schwenkbaren Stange eines Rücken- oder Armstützenträgers für Bürostühle. Device for adjusting the swiveling rod of a back or armrest supports for office chairs.

Die Erfindung betrifft eine Vorrichtung zum Verstellen des unteren Endes der schwenkbaren Stange eines Rücken-oder Armstützenträgers, wobei eine schiefe Ebene eines Gewindenutbolzens als Teil einer Verschraubung als Schwenkhilfe dient. Zum Unterschied vom Bekannten ist der Erfindungsgegenstand dadurch gekennzeichnet, daß der Gewindenutbolzen von einem darauf mittels Handhebels schraubend verdrehbaren Hut bzw. Gewinderohrstück umfangen ist, der mit einer Ringnut oder mit einer Ringleiste versehen ist, mit der das unt#re Ende der Stange gekuppelt ist.The invention relates to a device for adjusting the lower End of the swiveling rod of a back or armrest support, with an oblique Level of a threaded groove bolt serves as part of a screw connection as a swivel aid. In contrast to the known, the subject matter of the invention is characterized by that the threaded groove bolt can be rotated by screwing on it by means of a hand lever Hat or threaded pipe piece is encompassed with an annular groove or with a ring bar with which the lower end of the rod is coupled.

Erfinderische Ausgestaltungen dieses Hauptmerkmales sind: a) Das Kuppelglied des unteren Endes der Stange ist eine Gabel (vgl. Fig 3o) b) Das untere Ende der Stange greiit an eine im Querschnitt kreisrunde Leiste einer Ringleiste bzw. einer Kuppelecheibe sno Die Zeichnung zeigt zwei Ausführungbeispiele schematisch. Die Fig 1 stellt die eine Variante in einem Axialschnitt dar, zu der die Kuppelscheibe bzw. Drehscheibe Fig 2 gehört (Draufsicht). Die Fig 3 zeigt die Gabelvariante im Längsschnitt.Inventive refinements of this main feature are: a) The coupling element of the lower end of the rod is a fork (cf. schematic. 1 shows one variant in an axial section represents, to which the coupling disk or turntable Fig 2 belongs (top view). 3 shows the fork variant in longitudinal section.

Zur Vorrichtung zum Verstellen des unteren Endes der schwenkbaren Stange eines Rücken- oder Armstützenträgers gehört eine schiefe Ebene eines Gewindenutbolzens als Schwenkhilfe.For the device for adjusting the lower end of the pivotable Rod of a back or armrest support belongs to an inclined plane of a threaded groove bolt as a swivel aid.

Nach Fig 1 ist der Gewindenutbolzen 10 von einem darauf mittels Handhebels 3 schraubend verdrehbaren Hut 6 umfangen, der mit einer Ringnut R oder mit einer Ringleiste versehen ist, mit der das untere Ende 2b der Stange 2a, 2b gekuppelt ist. Der Gewindenutbolzen 10 ist mittels der Schraube 11 am Stuhlträger 1a, 1b festgestellt.According to Fig. 1, the threaded groove bolt 10 is placed on it by means of a hand lever 3 screwed twistable hat 6 encompassed with an annular groove R or with a Ring bar is provided with which the lower end 2b of the rod 2a, 2b is coupled is. The threaded groove bolt 10 is fixed by means of the screw 11 on the chair support 1a, 1b.

Nach Fig 3 ist das Kuppelgiied des unteren Endes 2b der Stange 2a, 2b eine Gabel 2w.According to Fig. 3, the coupling element of the lower end 2b of the rod 2a, 2b a fork 2w.

Durch Verschwenken des Handhebels 3 um die Achse G schraubt sich das Teil 6 bzw. 12 gegenüber dem Gewindebolzen 10 aufwärte oder abwärts, da der Bolzen 8 als Gewindezahn wirkt. Dabei wird der Arm 2b um den Zapfen 5 aufwärts oder abwärts werschwenkt und damit der Rückenstützenträger /By pivoting the hand lever 3 about the axis G, the part 6 or 12 screws upwards or downwards with respect to the threaded bolt 10, since the bolt 8 acts as a threaded tooth. The arm 2b is moved upwards or downwards around the pin 5 swiveled back and thus the backrest carrier /
