Definitions

  • 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.
  • 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.
  • the object of the invention is an orderly winding of the cable in layers on the spool in all Operating states.
  • 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.
  • 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.
  • a stable storage and alignment of the components is achieved in that the coil approximately vertically aligned strips of a frame is mounted.
  • a in the foot wall of the frame Insert for guiding the cable is arranged.
  • a guide roller in the foot ends of the strips on the winding side of the coil is stored.
  • the lamp suspension has a base plate 1 for attachment to a ceiling or other support element.
  • a frame 2 with two substantially vertically aligned strips 25 and a foot wall 26.
  • 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.
  • 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.
  • the coil 3 is rotatably mounted in the frame 2 on a fixed pin 9.
  • a return spring 10 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.
  • 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.
  • the cable 6 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.
  • the cable 6 requires about two winding layers on the for the usual cable length of 1 m to 1.3 m Coil 3.
