Definitions
- the invention relates to a luminaire grid according to the preamble of claim 1.
- a similar luminaire grid is already known from DE 30 05 762 C2.
- the transverse lamella is provided with a transverse slot on the underside, the lower edge of each cutout of the external reflectors being inserted into a transverse slot of a transverse lamella for fastening the transverse lamella to the outer reflector.
- the cross lamella had to be suspended in the outer reflector in the form of a circular movement in order to mount the two parts in the correct position, i.e. H. to bring the cross lamella into the outer reflector.
- the transverse slit of the transverse lamella was first inserted into the cutout of the outer reflector and then the transverse lamella was pivoted onto the outer reflector with a circular arc movement, with projections being provided on the outer reflector, which latched into assigned locking slots on the transverse lamellae.
- a further luminaire grid is known from EP-A-268 986. Here it is intended to insert a lamella into the side reflectors from the underside of the luminaire grid.
- a disadvantage of this document is that the lamella must be pressed together by hand for assembly. A two-axis movement is therefore necessary, namely compression on the one hand and insertion of the lamella in the direction perpendicular thereto on the other hand.
- the assembly of the transverse slats on the assigned reflectors can only be carried out in a complex manner.
- the present invention is therefore based on the object of achieving a fastening between a transverse lamella and an outer reflector of a luminaire grid, which can be carried out mechanically in a simple manner.
- the invention is characterized in that in each case the tabs (9, 15, 16, 17) opposite one another at an end face of the transverse lamellae (1) at their free front ends in the longitudinal direction of the wedge surfaces (17)
- Cross blades are conically bent inwards, and that in the area of the end face of the cross blades on each tab a laterally outward extension (9) is formed, and the cross blades (1) in the longitudinal direction straight into the respective cutout (3) of the perpendicular External reflectors (2) can be inserted and are designed to be resiliently snap-in by means of the lateral shoulders perpendicular to the direction of insertion.
- Such shoulders can be produced by bending the material of the transverse lamella to form an outwardly deformed edge which protrudes from the plane of the transverse lamella. It is also possible to produce this paragraph by forming a bead.
- the front edges of the transverse lamella are conically bent in the manner of wedge surfaces in the longitudinal direction of the transverse lamella.
- the bending of the front edges of the transverse lamella can be accomplished in a simple manner, and in connection with the conical wedge surfaces, a simple central entry into the cutout of the outer reflector results.
- the nose has inclined edges in the direction of insertion, which on the one hand correspond to the outer contour of the outer reflector and on the other hand are directed perpendicular to the cross section of the outer reflector. So the nose fits positively on one side of the outer reflector.
- leading edges are created in the area of the nose, which secure after the retraction of the transverse lamella on the underside in the area of the cutout of the outer reflector.
- an outer reflector 2 is shown with a section 3 of Figure 3, in which a transverse lamella 1 is inserted.
- FIG. 1 it can be seen that on the underside of the transverse lamella 1, a straight nose 8 that can be inserted into the outer reflector 2 is designed as a stop edge, and that the walls 4, 5 of FIG. 2 of the transverse lamella 1 have outwardly facing shoulders 9, which Pass through the cutout 3 according to FIG. 3 in the outer reflector 2 and rest against the outside 10 of the outer reflector 2 in a latching manner over its entire length.
- a stop edge 6 is formed which bears on the inside 7 of the outer reflector 2.
- the nose 8 according to FIGS. 1 and 2 arises in connection with edges 12 and 13 by bending the transverse lamella 1 according to FIG. 4 along the bending line 20.
- the nose 8 here forms edges 12, 13 which run obliquely in the direction of insertion - in particular according to FIG. 1 - which here correspond on the one hand to the edge 13 of the outer contour of the outer reflector 2 and on the other hand here the edge 12 is directed perpendicular to the cross section of the outer reflector 2.
- the nose 8 moves in a straight direction to the lower edge 19 of the cutout 3 according to FIG. 3, while the stop edge 6 comes to rest on the inside 7 of the outer reflector 2.
- paragraphs 9 can be seen, which are preferably produced by bending the material, wherein a V-shaped cross section of the transverse lamella is created by bending along the bending line 20 according to FIG. 4 with lateral over the surfaces of the walls 4, 5 to the outside indicative paragraphs 9.
- the front edges 11 of FIG. 4 of the transverse lamella 1 are conically bent inward in the manner of wedge surfaces in the longitudinal direction of the transverse lamella, as a result of which the wedge surfaces 17 are formed according to FIG. 2.
- the transverse lamella 1 can be inserted particularly easily into the cutout 3 according to FIG. 3, the shoulders 9 traversing the cutout 3 and then resting against the outside 10 of the outer reflector 2 according to FIG. 1.
- a linear, contour-conforming contact of the transverse lamella 1 on the outer reflector 2 is ensured.
- the stop edge 6 and the nose 8 hold the transverse lamella on the inside 7 of the outer reflector 2 in the opposite direction to the paragraphs 9.
- FIG. 1 it can be seen that in connection with the wedge surfaces 17 according to FIG. 2 the edge 13 and the inlet slope 14 facilitate the insertion of the transverse lamella 1 into the cutout 3.
- a bevel 16 is also formed on the end face of the transverse lamella 1 in the region of the wedge surfaces 17, such as a leading edge 18, as a result of which the transverse lamella can be easily inserted into the cutout 3 even if the transverse lamella is accidentally placed obliquely on the cutout.
