Description
Aufhängevorrichtung für Beleuchtungskörper, insbesondere elektrische Lampen Die im Hauptpatent beschriebene Einrichtung zur Aufhängung von Beleuchtungskörpern im Freien an Spannseilen, bei welchem eine windsichere Versteifung der Aufhängung dadurch erzielt wird, daß die Armatur gleichzeitig starr mit beiden parallelezi, Seilen verbunden ist, läßt sich auch noch in anderer Form zur Ausführung bringen, wie dieses auf der beiliegenden Zeichnung in einem Ausfüh- . rungsbeispiet nach Fig. i und 2 dargestellt ist.Suspension devices for lighting fixtures, in particular electric Lamps The device described in the main patent for suspending lighting fixtures outdoors on tension ropes, with which a windproof stiffening of the suspension is achieved in that the valve is rigid with both parallelezi, Connected to ropes, can also be carried out in another form, like this on the accompanying drawing in one execution. example according to Fig. I and 2 is shown.
Gemäß dieser Abänderung wird der Beleuchtungskörper zwischen den Spannseilen, angebracht, indem @er durch unverrückbar an ihm sitzende starre Zwischenglieder, bieispielsweise Stege, mit beiden Seilen verbunden ist. Es wird dadurch wiederum eine starre Ebene mit den Seilstücken hergestellt, die zwischen den Zwischengliedern liegen. Gleichzeitig wird aber auch die denkbar beste Form für die Widerstandsfähigkeit des Beleuchtungskörpers selbst gegen Winddruck erreicht.According to this modification, the lighting fixture is placed between the tension cables, attached by @ he by immovably seated rigid intermediate links, for example bridges, connected with both ropes. It becomes through this in turn a rigid plane is made with the pieces of rope between the intermediate links lie. At the same time, however, it is also the best possible shape for resilience of the lighting fixture even against wind pressure.
Die Zeichnung zeigt die beiden Seile 3 und q., die so weit auseinanderliegen, daß der Beleuchtungskörper x dazwischengebracht ist. Die Armatul^enschale 2 ist mit den Streben 5 verbunden, die mit den Klemmen 8 an den Seilen befestigt sind. Der Winddruck, der beispielsweise auf die Glocke i wirkt und bestrebt ist, diese senkrecht zur Zeichenebene zu bewegen, findet sehr große Widerstandsmomente, die an dem Hebelarm von der Befestigung 7. bis zu den` Klemmen 8 ängreifen. Auch ein starker Wind wird datier nicht in der Lage sein, den Beleuchtungskörpier zu verdrehen. Der ganze Beleuchtungskörper ist gewissermaßen in die starre Ebene, die aus den Seilstücken und den Armen gebildet wird, hineingelegt.The drawing shows the two ropes 3 and q., Which are so far apart that the lighting fixture x is interposed. The Armatul ^ enschale 2 is connected to the struts 5, which are attached to the ropes with the clamps 8. The wind pressure that acts, for example, on the bell i and strives to this Moving perpendicular to the plane of the drawing finds very large moments of resistance, the on the lever arm from the fastening 7. to the clamps 8. Also a strong winds will not be able to twist the lighting fixture. The whole lighting fixture is in a sense in the rigid plane that consists of the Pieces of rope and the arms is formed.
