Die in den Figuren 1 und 2 dargestellte und insgesamt mit dem Bezugszeichen 10 versehene Gelenkstange umfaßt im wesentlichen ein Rohr 11 sowie zwei stirnseitig an diesem Rohr 11 befestigte Beschlagteile 12, welche zum möbelseitigen Festlegen der kompletten Gelenkstange 11 an einem Sitz- oder Liegemöbel dienen.The one shown in FIGS. 1 and 2 and overall with the reference number 10 Articulated rod provided essentially comprises a tube 11 and two ends fitting parts 12 fastened to this tube 11, which are used for fixing on the furniture side serve the complete joint rod 11 on a sitting or lying furniture.

Das Rohr 10 kann in an sich bekannter Weise mit Hebeln 13, 14 für die Betätigung weiterer Beschlagteile ausgestattet sein, dies ist aber für die vorliegende Erfindung hier von untergeordneter Bedeutung.The tube 10 can in a manner known per se with levers 13, 14 for actuation be equipped with other fitting parts, but this is for the present invention of minor importance here.

Wie aus Figur 3 deutlich hervorgeht, ist an jedem Beschlagteil 12 eine aus Kunststoff gefertigte Lagerbuchse 15 angenietet. Diese Lagerbuchse 15 ragt jeweils in das stirnseitige Ende des Rohres 11 hinein. Wie Figur 4 deutlich macht, ist der Niet 16 gleichzeitig Drehlager für die Lagerbuchse 15. Gemeinsam mit der Lagerbuchse 15 ist mit dem Niet 16 eine Sicherungsscheibe 17 am Beschlagteil 12 festgelegt.As is clear from FIG. 3, there is one made of plastic on each fitting part 12 manufactured bearing bush 15 riveted. This bearing bush 15 projects into each end of the tube 11 into it. As shown in FIG. 4, the rivet is 16 at the same time pivot bearing for the bearing bush 15. Together with the bearing bush 15 a locking washer 17 is fixed to the fitting part 12 with the rivet 16.

Diese Sicherungsscheibe 17, die in den Figuren 5 und 6 dargestellt ist, weist eine Vielzahl von radial verlaufenden, federnden Laschen 18 auf, die gegenüber der Längsachse der Lagerbuchse 15 und somit auch des Rohres 11 geneigt verlaufen, und zwar in Richtung des jeweiligen Rohrendes.This locking washer 17, which is shown in Figures 5 and 6, has one A plurality of radially extending, resilient tabs 18, which are opposite to the The longitudinal axis of the bearing bush 15 and thus also of the tube 11 run inclined, in the direction of the respective pipe end.

Das Rohr 11 kann unter Ausnutzung der Federfähigkeit dieser Laschen 18 problemlos auf die jeweilige Lagerbuchse 15 aufgeschoben werden, bis das jeweilige stirnseitige Ende des Rohres an einem Flansch 19 der Lagerbuchse 15 definiert anliegt. Ein Lösen des Rohres 11 bzw. ein Abziehen des Rohres 11 von der Lagerbuchse 15 ist nun nicht mehr möglich, da sich dabei die Enden der federnden Laschen 18 in die Rohrwandung eingraben würden.The tube 11 can easily take advantage of the resilience of these tabs 18 be pushed onto the respective bearing bush 15 until the respective end face End of the tube bears against a flange 19 of the bearing bush 15 in a defined manner. Loosening the tube 11 or pulling the tube 11 off the bearing bush 15 is no longer possible because the ends of the resilient tabs 18 in the Would dig into the pipe wall.

Es ist somit eine ausgezeichnete, axiale Verbindung zwischen dem Beschlagteil 12 einerseits und dem Rohr 11 andererseits hergestellt.It is thus an excellent axial connection between the fitting part 12 on the one hand and the tube 11 on the other hand.

Das Rohr 11, die Beschlagteile 12 und die Sicherungsscheiben 17 sind in an sich bekannter Weise aus Metall hergestellt, so daß sich insgesamt ein guter elektrischer Kontakt zwischen den genannten Bauteilen ergibt, womit der Vorteil erzielt wird, daß sich eine nach der Komplettmontage der Gelenkstange 10 erforderliche Pulverbeschichtung problemlos durchführen läßt. Weitere Vorteile ergeben sich aus der einfachen ggfs. vom Händler oder Kunden durchzuführenden Endmontage sowie aus der daraus resultierenden Transporterleichterung, durch den Wegfall sperriger, bereits vormontierter Gesamteinheiten.The tube 11, the fitting parts 12 and the locking washers 17 are in themselves known manner made of metal, so that overall a good electrical Contact between the above components results, with which the advantage is achieved that a powder coating required after the complete assembly of the joint rod 10 can be easily carried out. Further advantages result from the simple final assembly to be carried out by the dealer or customer if necessary the resulting ease of transportation, by eliminating bulky, pre-assembled total units.

Beim Ausführungsbeispiel gemäß den Figuren 1 - 4 ist die jeweilige Sicherungsscheibe 17 gemeinsam mit der Lagerbuchse 15 am Beschlagteil 12 angenietet. Abweichend hiervon kann naturgmäß eine Sicherungsscheibe 17 auch separat am Niet 16 befestigt werden, z. B. durch Annieten oder Anschrauben an der Stirnseite.In the exemplary embodiment according to FIGS. 1-4, the respective locking washer 17 riveted together with the bearing bush 15 on the fitting part 12. Deviating from this, a locking washer 17 can of course also be separately on Rivet 16 are attached, e.g. B. by riveting or screwing on the front side.

Bei dem Ausführungsbeispiel nach den Figuren 1 - 4 greift die jeweilige Sicherungsscheibe 17 ins Innere des Rohres 11 ein.In the exemplary embodiment according to FIGS. 1-4, the respective locking washer engages 17 inside the tube 11.

Die Figur 7 zeigt eine alternative Lösung, die darin besteht, daß die Sicherungsscheibe 17 mit ihren federnden Laschen 18 das Rohr 11 auch außenseitig umschließen kann. Dabei ist die Sicherungsscheibe 17 in einen Lagerschlitz 20 eines entsprechend gestalteten Beschlagteiles 12 eingeschoben. Das Beschlagteil 12 ist bei der Lösung nach Figur 7 vorteilhafterweise aus Kunststoff hergestellt.Figure 7 shows an alternative solution, which consists in that the locking washer 17 with its resilient tabs 18, the tube 11 also on the outside can enclose. The locking washer 17 is in a bearing slot 20 one appropriately designed fitting part 12 inserted. The fitting part 12 is 7 advantageously made of plastic in the solution according to FIG.
