Description

Kugelgelenk für Beleuchtungskörper. Es gibt bereits Kugelgelenke für Beleuchtungskörper, bei denen die beiden Gelenkteile durch eine Schraubenfeder gegeneinandergepreßt werden. Nach der vorliegenden Erfindung wird die Schraubenfeder durch eine doppelkegelförmige oder harmonikaähnliche Feder, die aus flachem Blech hergestellt ist, ersetzt. Eine solche Feder hat vor den früher verwendeten den Vorzug der kürzeren Baulänge, der größeren Leichtigkeit und eines gleichmäßigeren Druckes an der Peripheri.Ball joint for lighting fixtures. There are already ball joints for Lighting fixtures in which the two joint parts are pressed against one another by a helical spring will. According to the present invention, the helical spring is by a double cone-shaped or accordion-like spring made of flat sheet metal. One Such a spring has the advantage of a shorter length over the previously used greater lightness and more even pressure on the periphery.

Auf der beiliegenden Zeichnung ist der Erfindungsgegenstand in einer Ausführungsform dargestellt. ##£bb. i stellt das Gelenk im Längsschnitt dar, Abb. 2 in Draufsicht; Abb. 3 und 4 zeigen in stark vergrößertem Maße die Form der Federdruckscheiben. Die Kugel a ist in dem Körper b drehbar Cr -- gelagert. Der Ring c wird durch die Fede! scheiben d d infolge Einschrauben der Gewindebuchse e in den Körper b federnd gegen die Kugel a gepreßt.The subject of the invention is shown in one embodiment in the accompanying drawing. ## £ bb. i shows the joint in longitudinal section, Fig. 2 in plan view; Fig. 3 and 4 show the shape of the spring pressure washers on a greatly enlarged scale. The ball a is rotatably supported in the body b for Cr -. The ring c is made by the spring! disks dd as a result of screwing the threaded bushing e into the body b resiliently pressed against the ball a.

Die Federscbeiben d d sind tellerförmig, wie in Abb. I dargestellt ist.The spring washers dd are plate-shaped, as shown in Fig. I.
