Definitions

  • the invention relates to a luminaire grid according to the preamble of claim 1.
  • each transverse lamella is thus connected to the outer reflector at three points, the latter engaging in corresponding slots in the transverse lamella.
  • the walls of the transverse lamella must be pressed against one another during assembly and then - in order to ensure a permanent connection - be fixed in their engagement position by an additional cover strip. This also ensures that the walls of the transverse lamella rest on the edges of the cutout in the outer reflector, so that the desired contour of the transverse lamella is thereby determined.
  • the target contour of the external reflector is only fixed by the slots in the transverse lamella, i.e. only by two points, so that the shape of the thin external reflectors, which can be easily bent during assembly, often deviates from the desired target contour.
  • the invention has for its object to develop a luminaire grid of the type mentioned so that a rigid and permanent connection between the cross blades and the outer reflectors is ensured with simple manufacture and assembly and clearly reproducible target contour of cross blades and side reflector.
  • the invention is characterized by a very stable and rigid connection between cross blades and outer reflector, which is also due to the fact that very narrow manufacturing tolerances are possible with the invention without affecting the assembly:
  • Each cross blade is only with its lower cross slot in the Hook in the cut-out of the external reflector and then swivel it around this pivot point into the recess as far as it will go, whereby the walls are gripped by the guide slots and first pressed against the projections and after reaching the desired position against the edges of the cut-outs. This means that neither a prior bending of the walls nor the introduction of additional locking means is necessary.
  • the outer reflector In a luminaire grid known from DE-B-28 33 010, the outer reflector is in three points on the cross lamella; nevertheless, a certain target contour with sufficient accuracy with very low manufacturing tolerances is only possible with difficult assembly. Furthermore, the stability of the connection also leaves something to be desired, since the spring tabs in the cross slats easily slip through the cutouts in the outer reflectors when the cross slats are pressed somewhat out of the 90 ° position, which cannot be avoided when mounting the long grids . Finally, when manufacturing the transverse lamellas, care must be taken to ensure that the spring tabs are not squashed when the V-shaped profile is bent. In the invention, however, the transverse fins only have slots that do not interfere with the bending process.
  • connection between intersecting slats with a V-shaped cross section is also known, in which the desired position is secured by projections which engage in corresponding recesses in the other slat.
  • the one slat is inserted from above into the open cutout, its walls being pressed against one another to such an extent that they fit past the projections. Accordingly, the walls of the transverse slats only resiliently rest against the edges of the cutouts in their desired position.
  • the two approximately V-shaped walls 21, 22 of a transverse lamella 2 form at the bottom a transverse edge 20 into which short, upwardly extending transverse slots -201 are embedded; its width is approximately equal to the thickness of the wall of the associated external reflector, designated 1, and its inclination corresponds to that of the external reflector.
  • This has a cutout 10 for each transverse lamella with continuously curved lateral edges 101, against which the walls 21, 22 of the transverse lamella rest, so that their curvature is determined by the contour of the edges of the cutout 10.
  • the cutout 10 has two guide slots 100 at the upper end.
  • Each of these guide slots is delimited by an outer edge 103 which continuously merges into the edge 101 of the cutout 10 and an inner edge 104; the latter forms at least part of its length an acute downward open angle with the outer edge 103, so that a wedge-shaped guide slot is formed, the end piece of which has approximately parallel edges, the distance of which corresponds to the thickness of the walls of the transverse lamella.
  • arcuate projections 105 protrude from the contour of the recess 10 by approximately the thickness of the walls of the transverse lamella; these projections are in the upper third of the recess.
  • This transition has a leading edge 200 which runs obliquely from the outside inwards, to which a latching edge 205 adjoins there is approximately perpendicular to the associated surface of the outer reflector. This is then followed by a stop step 206, which extends approximately tangentially to the surface of the outer reflector 1 ′ which lies there.
  • the locking edge 205 is spaced from the bottom of the associated transverse slot 201 such that the transverse lamella 2 inserted into the cutout 10 is pressed against the lower edge 102 of the cutout 10 by the guide slots 100 acting on the locking surface 205.
  • the transverse lamella is held in this desired position by the projections 105, which engage in the desired position in the associated locking slots 202 in the walls 21, 22 of the transverse lamellae.
  • These locking slots lie on the curve according to which the outer reflector 1 is to run.
  • the outer reflector 1 is preferably slightly more curved in the prefabrication, so that it bears against the stop step 206 and the transverse slot 201 after being plugged together with the transverse lamellae.
  • an outer reflector 1 to a transverse lamella 2
  • the latter is first inserted with its transverse slot 201 into the lower edge 102 of the cutout 10 of the outer reflector and then pivoted about this point into the cutout 10, the oblique contact surfaces 201 being easily gripped by the wedge-shaped guide slots 100 will.
  • the latching surfaces 205 of the walls 21, 22 of the transverse lamella 2 run into the end pieces delimited by parallel edges; the walls are stretched through and over the projections 105.
  • the projections 105 then engage through the locking slots 202, the walls 21, 22 springing against the edges 101 of the cutout.
