Definitions

  • the present invention relates to a lamp with suspension devices for hanging and folding a grid used in the lamp housing, the suspension devices each comprising a carrier which can be moved up and down between an upper and a lower position in an anchoring part connected to the lamp housing and which can be removed the grid can be detached from the anchoring part, a holding part connected to the longitudinal reflector of the luminaire grid with bearing holes into which the lower ends of the carrier are inserted so as to be pivotable about a horizontal axis.
  • a lamp with a suspension device for the lamp grid of the aforementioned type is known.
  • the support is made in one piece from sheet metal by stamping and bending and has a holding projection with which it rests in its lower position on a support of a compression spring part.
  • the carrier In its upper position, the carrier is locked with the compression spring part.
  • the carrier can be unhooked manually against the force of the compression spring from the compression spring part.
  • the compression spring part is also a part made of sheet metal by stamping and bending from resilient metal. It is connected to the ceiling of the lamp housing via tines at the upper end and also has a tongue-shaped leaf spring which is bent by a vertical leg of the carrier.
  • the compression spring part has approximately the height of the carrier.
  • the object of the present invention is to further develop a luminaire with a suspension device for the grid of the aforementioned type with a view to simplifying the manufacture of the individual parts of the suspension device while maintaining the functions mentioned.
  • a luminaire according to the invention with a suspension device of the type mentioned at the beginning, with the characteristic features of the main claim.
  • a spring clip bent from a wire is used as the carrier, the lower ends of the bracket are bent outwards and penetrate the bearing holes of the bearing legs, which are located in the lower region of the holding part, so that the holding part with the grid around through the ends of the bracket the horizontal axis of rotation given the spring clip can be pivoted if the grid is to be folded down by 90 °.
  • the anchoring part for fastening the spring clip in the side wall of the lamp housing is considerably smaller in vertical extent than in the previously known embodiment.
  • the spring loading of the support to be suspended does not only result from an interaction between the support and the anchoring part inserted into the lamp housing, but the necessary spring loading of the support when pulled down is due solely to the spring action of the resilient legs as resilient wire bracket formed spring clip, which serves as a carrier according to the invention.
  • FIG. 1 shows a cross section through a luminaire according to the invention with a luminaire housing 11 with a rectangular cross section with a housing ceiling and two side walls, in which a fluorescent lamp 12 extending in the longitudinal direction is arranged.
  • the lamp has a lamp grid with longitudinal reflectors 13 and cross blades 15. It is a well-known luminaire grid.
  • the suspension device comprises the holding parts 17, which are shown in detail in FIG. 6.
  • the longitudinal reflectors 13 rest against these holding parts 17, the latter being bent in a hook shape at the upper end and thus reaching over the holding parts.
  • both holding parts 17 and longitudinal reflectors 13 are bent twice at approximately right angles, first outwards and then upwards, so that the longitudinal reflectors 13 have a type of channel into which a correspondingly shaped channel 19 of the holding part is inserted .
  • the suspension device further comprises spring clips 26 formed from wire clips, which are shown in more detail in FIGS. 5, 5a and 5b and are described in more detail below. These spring clips are inserted with their two lower outward-pointing temple ends 21 into the bearing holes 24 in bearing legs 22 of the holding parts 17 formed at the bottom (see FIG. 6).
  • the suspension device also includes the anchoring parts, which are inserted into recesses 14 in the side walls of the lamp housing 11 (see FIG. 2).
  • the anchoring part 33 is shown in more detail in FIGS. 4, 4a, 4b, 4c and 4d and is described in detail below.
  • the spring clips 26 serving as supports for the luminaire grid are connected to the anchoring parts 33, wherein the spring clips can be pulled down from an upper position, which is shown in FIG. 1, to hang the grid into the lower position according to FIG the anchoring parts 33 are guided.
  • the spring clip assumes a position in which its two long straight legs 28, 29 lie vertically and run parallel to the side wall of the lamp housing 11, the upper loop 27, which the two straight legs 28 , 29 connects at the upper end of the spring clip 26, is located approximately in the corner region of the lamp housing 11 just below the housing ceiling and at approximately the same height as the upper end of the longitudinal reflector 13.
  • the two straight legs 28, 29 are each bent a little towards the inside in the lower third of the spring clip, so that there is a narrowing 30, where the two legs of the spring clip a smaller distance have than in the top two thirds of the spring clip.
  • the two legs each have an outward bend, so that an enlargement 31 results below the constriction 30.
  • the clear distance between the two straight legs 28, 19 in the upper section of the spring clip is, for example, about 5.5 mm.
  • the clear distance in the area of the constriction 30 between the two legs of the spring clip is, for example, approximately 2.5 mm and the clear distance between the two legs in the area 31 of the extension 31 is approximately 12.5 mm.
  • the section between the straight legs 28, 29 and the constriction 30 has an angle of approximately 15 ° inwards to the straight legs and between the constriction 30 and the extension 31 the two legs of the spring clip are angled outwards by approximately 30 °.
  • both legs are then first bent backwards and then finally in the lowest section follows a bend at right angles to the outside, so that the lower bracket ends 21 are horizontal and at right angles to the upper straight sections 29 of the spring clip extend outwards, the lower bow ends 21 also extending in a plane which lies behind the plane which the two legs 28, 29 of the spring clip in the upper section up to the extension 31. This can be seen from FIGS. 5a and 5b.
  • This anchoring part 33 is a stamped and bent part made of sheet metal and consists in the lower part of two vertical legs 34 which are bent in the lateral region above by approximately 180 °, so that these legs have downwardly extending sections 35 which, how recognizes in Fig. 2, reach through a recess 14 in the side part of the housing 11. These downwardly bent sections 35 are bent inward in the lower region to form hooks 39 which claw into the sheet metal of the housing 11 of the lamp.
  • the legs 34 and their bent portions 35 are resiliently connected to one another so that the bent portions 35 with the hooks 39 can be pushed over the sheet metal of the side parts of the housing 11 in order to fasten the anchoring part 33 to the sheet metal of the housing.
  • the anchoring part 33 also has a central vertical section 38 and two angled webs 36 which adjoin it laterally and are at right angles to this. These angled webs 36 are reversely L-shaped, their vertical legs being at right angles to the central vertical section 38 extend to the front and are angled to horizontal tabs 37 only in a front area at the top at right angles to the side.
  • the spring clip 26 In the upper position of the spring clip 26, its two legs each abut the upper horizontal edge 36a of the angle webs 36 of the anchoring part 33.
  • the spring clip is in such a position relative to the anchoring part that the two legs rest in the area between the constriction 30 and the extension 31 on the edge 36a, the two legs of the spring clip being somewhat under spring tension.
  • the lower bracket ends 21 are in the bearing holes 24 of the bearing legs 22 of the holding part 17.
  • the spring clip 26 can now be pulled down against the spring tension of its two legs, which are pressed against one another, the two legs being bent outwards.
  • the spring clip 26 can be pulled down more easily, the two long straight legs 28, 29 of the spring clip then sliding behind the front horizontal tabs 37 of the anchoring part until the horizontal connecting web of the upper loop 27 on the Edge 36a abuts so that further pulling down of the spring clip is blocked.
  • the position shown in FIG. 3 is then reached.
  • the right spring clip 33 can now be released from the right anchoring part 26 by, as indicated by the arrow 1 in FIG. 3, the spring clip being raised a little and then also, as indicated by the arrow 2, inwards is pivoted.
  • the spring clip is thereby released from the anchoring part, since the loop 27 is lifted over the upper horizontal tabs 37 of the angled webs 36 of the anchoring part 33.
  • the grid can be suspended, the left spring clip 26 hanging on the left anchoring part and the holding part 17 together with the grid with the longitudinal reflectors 13 around the through the bracket ends 21 of the left spring clip and the bearing holes 24 of the holding part 17 given horizontal axis pivots.
  • the end position of the grid pivoted through 90 ° is shown in FIG. 3 by dash-dotted lines.
