Definitions

  • the invention relates to a luminaire grid according to the preamble of claim 1, as is known from DE-A-2 758 261 (see also FR-A-2 413609).
  • the invention has for its object to design the luminaire grid according to the preamble of claim 1 so that cross blades and outer walls are easier to assemble.
  • the outer wall 1 has a grid edge 10 adjacent to a light exit opening and a resilient edge leg 11 bent back from there in a V-shape with a rectangular holding slot 12 which is closed on both sides and which has a counter edge 120 on the end facing away from the grid edge 10 and on the opposite side a lower edge 121 is limited.
  • the outer wall 1 has two plug-in slots ' 1.1, 1.2 for each transverse lamella 2. The width of these plug-in slots and that of the holding slot 12 corresponds to the material thickness of the Giuerlamelle 2.
  • the course of the end face 200 of the transverse lamella 2 is adapted to the shape of the adjacent outer wall 1 of the luminaire grid in such a way that it bears practically seamlessly against this outer wall;
  • the outer wall 1 is formed in a straight line in the region of the transverse lamella 2.
  • Two hook-shaped retaining tabs 2.1, 2.2 protrude from the end face 200 of the transverse lamella 2 at a distance from one another, each of which has an open undercut 20 directed against the raster edge 10 with the end face 200. close, the width of which corresponds to the material thickness of the outer wall.
  • the retaining tabs are dimensioned such that they can be inserted through the plug-in slots 1.1, 1.2 - FIG. 1.
  • the lower retaining tab 2.2 adjacent to the raster edge 10 is dimensioned such that in this position, shown in FIG. 1, it supports the edge leg 11 not yet touched.
  • the transverse lamella 2 is then pressed from the position shown in FIG. 1 by a movement in the direction of arrow P into the solo position shown in FIG. 2.
  • the edge leg 11 is first pressed away by a locking piece 2.21 of the holding tab 2.2 until the beginning of the locking edge 21 engages in the holding slot 12 and thereby lies against the opposite edge 120.
  • the edge leg 11 springs back again, the counter edge 120 sliding along the locking edge 21 which extends at an acute angle to the edge leg 11.
  • the target position is reached when an end edge 22 of the holding tab 2.2 meets the lower edge 121 of the holding slot 12.
  • Shape and dimensions are chosen so that a game S remains in the area of the undercuts 20 between the retaining tabs and the lower edges of the insertion slots 1.1, 1.2: The target position shown in FIG. 2 is therefore only due to the dimensions and tolerances of the shark slot 12 and Holding tab 2.2 determined.
