Heinrich W. Weisbach in Annaberg, Erzgeb. Aufhängevorrichtung für elektrische LampenHeinrich W. Weisbach in Annaberg, Erzgeb. Suspension device for electric lamps
Patentiert im Deutschen'Reiche vom 9. Dezember 1931 abPatented in the German Reich on December 9, 1931
Die Erfindung betrifft eine Aufhängevorrichtung für elektrische Lampen, bei welcher zwischen die in den Rohrstutzen schraubbare Mutter und den waagerecht verlaufenden Enden des zum Aufhängen des Lampenkörpers dienenden Tragbügels ein Isolierkörper geschaltet ist. Gegenüber einem bekannten Vorschlag dieser Art besteht die Aufhängevorrichtung gemäß der Erfindung darin, daß auch die zu den waagerechten Enden führenden Kniestücke des Tragbügels in diesen Isolierkörper eingebettet oder von diesem allseitig umschlossen s,ind. Damit ist die bei der bekannten Vorrichtung vorhandene Möglichkeit, der Berührung zwischen dem metallischen und daher stromleitenden Baldachin und dem ebenfalls metallischen und auch stromleitenden Tragbügel und somit jede Kurzschlußgefahr vermieden.The invention relates to a suspension device for electric lamps in which between the nut that can be screwed into the pipe socket and the horizontally extending nuts Connected ends of the bracket used to hang the lamp body, an insulating body is. Compared to a known proposal of this type, there is the suspension device according to the invention in that the knee pieces of the support bracket leading to the horizontal ends are also inserted into this insulating body embedded or enclosed on all sides by this s, ind. So that is the case with the well-known Device existing possibility of contact between the metallic and therefore conductive canopy and the metallic and also conductive canopy Carrying bracket and thus any risk of short circuit avoided.
Auf der Zeichnung ist der Erfindungsgegenstand in mehreren Ausführungen beispielsweise dargestellt.The subject of the invention is shown in several versions in the drawing, for example shown.
In allen fünf Abbildungen ist α der die Stromzuführungslitze b führende Rohrstutzen, der mit Außengewinde versehen ist. Gemäß Abb. ι (Vorderansicht), Abb. 2 (Seitenansicht) und Abb. 3 (Draufsicht) sitzt Unterhalb einer auf den Rohrstutzen α geschraubten Mutter c eine Scheibe d aus Kunstharz. In diese Scheibe d sind bei Augen d' die knieförmig verlaufenden Enden e' eines starren Drahtbügels e eingegossen. Außerhalb dieser Augen d' kann die Mutter c von den Fingern leicht erfaßt und gedreht werden, ohne den Bügel mitdrehen zu müssen.In all five figures, α is the pipe socket which carries the power supply strand b and is provided with an external thread. According to Fig. Ι (front view), Fig. 2 (side view) and Fig. 3 (top view), a washer d made of synthetic resin sits beneath a nut c screwed onto the pipe socket α. The knee-shaped ends e 'of a rigid wire bracket e are cast into this disk d at eyes d'. Outside of these eyes d ' , the nut c can easily be grasped and rotated by the fingers without having to rotate the bracket as well.
Die Kunstharzscheibe d kann vorteilhaft auch so ausgebildet sein, daß sie die Mutter c teilweise abdeckt, so daß sich letztere zwar allein drehen, nicht aber, z. B. beim Transport, verlorengehen kann.The synthetic resin disk d can advantageously also be designed so that it partially covers the nut c , so that the latter rotate alone, but not, for. B. during transport, can be lost.
Bei der Ausführung gemäß Abb. 4 und 5 sind die aus Stahl bestehenden knieförmigen Drahtbügelenden e' in je einer Kunstharzbacke h befestigt, und letztere werden durch den elastischen Stahldraht ständig gegen den Rohrstutzen gedrückt.In the embodiment according to Figs. 4 and 5, the knee-shaped wire bracket ends e ' made of steel are each fastened in a synthetic resin jaw h , and the latter are constantly pressed against the pipe socket by the elastic steel wire.
