Description

Die Erfindung betrifft eine Leuchtenaufhängung mit einem Kabel zum Heben und Senken der Leuchte, wobei eine Spule mit Flanschen, mit horizontal ausgerichteter Achse und mit einer Rückholfeder das Kabel in einer Schraubennut aufnimmt.The invention relates to a lamp suspension with a cable for lifting and lowering the Luminaire, a coil with flanges, with a horizontally aligned axis and with a return spring receives the cable in a screw groove.

Das Kabel zum Heben und Senken der Leuchte benötigt etwa zwei Wickellagen auf der Spule. Besonders bei einer stark beschleunigenden Rückholfeder besteht die Gefahr, daß sich das Kabel nicht ordnungsgemäß aufwickelt. Dieses führt zu Störungen bis zu Blockaden der Leuchtenaufhängung.The cable for lifting and lowering the lamp needs about two winding layers on the coil. Especially with a strongly accelerating return spring, there is a risk that the cable will not become loose properly wound up. This leads to malfunctions or blockages in the lamp suspension.

Aufgabe der Erfindung ist eine geordnete Aufwicklung des Kabels in Lagen auf der Spule in allen Betriebszuständen.The object of the invention is an orderly winding of the cable in layers on the spool in all Operating states.

Diese Aufgabe wird nach der Erfindung dadurch gelöst, daß am Überlaufende der Schraubennut die von dem benachbarten Flansch der Spule abgelegene Wandung der Schraubennut eine Überhöhung aufweist.This object is achieved according to the invention in that the screw groove at the overflow end the wall of the screw groove remote from the adjacent flange of the coil an increase having.

Die Erfindung unterscheidet sich insofern vom Stand der Technik, als die Überhöhung eine Führung des Kabels bis in den Überlaufbereich der Schraubennut zwangsweise sicherstellt. Das Kabel bewegt sich erst am Überlaufende der Schraubennut in die zweite Wickellage zurück.The invention differs from the prior art in that the cant is a guide of the cable into the overflow area of the screw groove. The cable moves only return to the second winding position at the overflow end of the screw groove.

Eine zusätzliche Führung des Kabels wird dadurch erreicht, daß die Wandung der Schraubennut etwa um 180° gegenüber der ersten Überhöhung versetzt eine weitere Überhöhung aufweist.An additional routing of the cable is achieved in that the wall of the screw groove has a further elevation offset by approximately 180 ° with respect to the first elevation.

Eine stabile Lagerung und Ausrichtung der Bauteile wird dadurch erreicht, daß die Spule in etwa vertikal ausgerichteten Leisten eines Rahmens gelagert ist.A stable storage and alignment of the components is achieved in that the coil approximately vertically aligned strips of a frame is mounted.

Zur Führung des Kabels beim Einlauf ist vorgesehen, daß in der Fußwandung des Rahmens ein Einsatz zur Führung des Kabels angeordnet ist.To guide the cable at the inlet, it is provided that a in the foot wall of the frame Insert for guiding the cable is arranged.

Zur Verminderung von Bewegungen und Verschiebung des Kabels beim Einlauf in die Nuten der Spule ist vorgesehen, daß in den Fußenden der Leisten auf der Aufwickelseite der Spule eine Führungsrolle gelagert ist.To reduce movement and displacement of the cable when entering the grooves of the Coil is provided that a guide roller in the foot ends of the strips on the winding side of the coil is stored.

Ein Ausführungsbeispiel wird anhand der Zeichnungen erläutert, in denen darstellen:

  • Fig. 1 einen Schnitt durch die Leuchtenaufhängung mit Baldachin,
  • Fig. 2 eine Unteransicht bei abgenommenem Baldachin,
  • Fig. 3 eine Einzelansicht der Spule und
  • Fig. 4 eine Stirnansicht der Spule.
    • An exemplary embodiment is explained with reference to the drawings, in which:
  • 1 shows a section through the lamp suspension with canopy,
  • 2 is a bottom view with the canopy removed,
  • Fig. 3 is a single view of the coil and
  • Fig. 4 is an end view of the coil.

    • Die Leuchtenaufhängung weist eine Grundplatte 1 zur Befestigung an einer Decke oder einem anderen Tragelement auf. An der Grundplatte 1 sitzt ein Rahmen 2 mit zwei im wesentlichen vertikal ausgerichteten Leisten 25 und einer Fußwand 26. In den Leisten 25 sind eine Spule 3 und fußseitig eine Führungsrolle 4 drehbar gelagert. Die Führungsrolle 4 ist aus der Mittelebene des Rahmens 2 herausgerückt, wie man der Fig. 2 entnimmt und was noch in Einzelheiten erläutert wird.The lamp suspension has a base plate 1 for attachment to a ceiling or other support element. On the base plate 1 sits a frame 2 with two substantially vertically aligned strips 25 and a foot wall 26. In the strips 25 there is a coil 3 and one on the foot side Guide roller 4 rotatably mounted. The guide roller 4 has moved out of the central plane of the frame 2, how to remove Fig. 2 and what will be explained in detail.

    Ein Einsatz 5 in der Fußwand 26 des Rahmens 2 hat eine Innenwand mit einem Innenwulst zur Fubrung eines Kabels 6 zum Heben und Senken einer nicht dargestellten Leuchte. Der Einsatz 5 nimmt auf einem Außengewinde einen Ring 7 eines Baldachins 8 auf, der die Deckenplatte 1 und den Rahmen 2 umschließt.An insert 5 in the foot wall 26 of the frame 2 has an inner wall with an inner bead Fubrung a cable 6 for lifting and lowering a lamp, not shown. The insert 5 takes on an external thread on a ring 7 of a canopy 8, which the ceiling plate 1 and the frame 2nd encloses.

    Die Spule 3 ist in dem Rahmen 2 auf einem feststehenden Zapfen 9 drehbar gelagert. In dem Zapfen 9 ist ein Ende einer Rückholfeder 10 gehalten, deren anders Ende an der Innenfläche der Spule 3 verankert ist. Eine im Einzelnen nicht erläuterte Rastvorrichtung ermöglicht ein ungehindertes Aufwickeln des Kabels, und eine Bremsvorrichtung hält das Kabel in jeder Stellung fest. Auf dem Zapfen 9 ist auch eine Schleifringanordnung 11 angebracht, die einerseits durch Leitungen 12 mit Anschlußklemmen 13 und andererseits mit Leitungen des Kabels 6 verbunden ist.The coil 3 is rotatably mounted in the frame 2 on a fixed pin 9. In the cone 9, one end of a return spring 10 is held, the other end of which is anchored to the inner surface of the coil 3 is. A locking device, not explained in detail, enables unimpeded winding of the cable, and a braking device holds the cable in every position. On the pin 9 is too a slip ring arrangement 11 attached, on the one hand through lines 12 with terminals 13 and on the other hand is connected to lines of the cable 6.

    Die Spule 3 weist auf dem Außenmantel eine Schraubennut 14 auf, die sich zwischen den Flanschen 15 und 16 erstreckt. In der Stirnfläche des Flansches 16 mündet eine von der Schleifringanordnung 11 ausgehende axiale Einführung 17 für das Kabel 6. Das Kabel 6 ist durch eine Ringnut 18 in den Einlaulbereich 19 der Schraubennut 14 geführt.The coil 3 has a screw groove 14 on the outer jacket, which is located between the flanges 15 and 16 extends. One of the slip ring arrangement opens into the end face of the flange 16 11 outgoing axial insertion 17 for the cable 6. The cable 6 is through an annular groove 18 in the inlet area 19 of the screw groove 14 out.

    Bei der Aufrollbewegung unter der Wirkung der Rückholfeder 10 legt sich das Kabel 6 in der Fußbereich der Schraubennut 14 ein. Am Überlaufende 20 der Schraubennut 14 weist die von dem Flansch 15 abgelegene Wandung der Schraubennut 14 eine Überhöhung 21 auf, um das Kabel zu führen und ein vorzeitiges Überspringen des Kabels 6 auszuschließen. Etwa um 180° in Umfangsrichtung versetzt ist eine weitere Überhöhung 22 der Wandung vorgesehen, die eine einwandfreie Führung des Kabels 6 bei der Bildung der zweiten Lage sicherstellt. Die Führungsrolle 4 führt das Kabel 6 auf die Aufwickelseite der Spule 3.When rolling up under the action of the return spring 10, the cable 6 lies in the Foot area of the screw groove 14. At the overflow end 20 of the screw groove 14 has the Flange 15 remote wall of the screw groove 14 on an elevation 21 to guide the cable and to rule out premature skipping of the cable 6. Offset about 180 ° in the circumferential direction a further elevation 22 of the wall is provided, which ensures proper routing of the cable 6 ensures the formation of the second layer. The guide roller 4 leads the cable 6 to the winding side the coil 3.

    Das Kabel 6 benötigt für die übliche Kabellänge von 1 m bis 1,3 m etwa zwei Wickellagen auf der Spule 3. Durch die Ausbildung der Überhöhungen 21 und 22 der Schraubennut 14 und durch die Führungsrolle 4 erreicht man eine sichere Führung und Verlegung des Kabels 6 beim Aufwickeln.The cable 6 requires about two winding layers on the for the usual cable length of 1 m to 1.3 m Coil 3. By the formation of the peaks 21 and 22 of the screw groove 14 and by the guide roller 4 you can safely guide and lay the cable 6 when winding.
