Definitions

  • the invention relates to a lamella grid with two side reflectors and a plurality of transverse lamellae arranged between them with V-shaped legs which have edge strips directed towards one another at their ends, the side reflectors having openings corresponding to the contour of the transverse lamellae through which the transverse lamellae are inserted.
  • the invention has for its object to simplify this relatively complex design in assembly.
  • the inventive solution to this problem is characterized in a lamella grid of the type mentioned in that between a narrow section of the edge strip in the end region of each transverse lamella and a wider section of the edge strip between the side reflectors there is a step that in the openings of the side reflectors in the center from above
  • a tongue protrudes in each case, the width of which is dimensioned such that the legs of the transverse lamellae are pressed firmly against the edge of the opening by the narrow sections of their edge strip lying against the edges of the tongue, such that at least one with its free end in the end region of each leg of a transverse lamella the opposite end region of the transverse lamella facing spring tab projects outwards, which is arranged so that it rests on the back of the side reflector and this on the one hand with its tongue against the step in the edge strip of the transverse lamella and on the other hand with a profile edge presses against the end edge of the cross lamella.
  • the assembly of a lamella grid according to the invention is reduced to a simple plugging together of transverse lamellae and side reflectors.
  • transverse lamellae 3 each have a V-shaped cross section.
  • Each side reflector has a U-shaped profile edge 12 which is open at the bottom.
  • the side reflectors 1, 2 have openings 11 for inserting the transverse slats 3; the contour of these openings corresponds to the desired course of the legs 31 of the transverse lamellae.
  • one of these openings 11 is shown with inserted cross plate 31 and one without cross plate.
  • a tongue 111 projects centrally from above into each such opening 11.
  • Each transverse lamella 3 has two legs 31 which have edge strips directed towards one another at their end; these edge strips have a wide section 312 in the area between the side reflectors 1 and 2 and a narrow section 311 outside the side reflectors. A step 313 lies between each of these sections (FIG. 3). From the narrow section 311 to the end edge 30 of the transverse lamella, the width of the edge strip tapers continuously, which makes it easier to plug it together.
  • the narrow sections 311 are supported against the edges of the tongues 111, the width of which is dimensioned such that the legs 31 of the transverse slats 3 are pressed firmly against the edges of the opening 11 by these tongues (FIG. 2).
  • Two spring tabs 314, 316, 315 and 317 are bent out from the end region of each leg 31 of a transverse lamella 3 at a distance from one another, in such a way that the free ends of these lobes are each directed towards the opposite end region of the transverse lamella.
  • These spring tabs stand out from the plane of the legs of the transverse lamellae about the material thickness of these legs out (Fig. 4).
  • the position of these spring tabs is chosen and adapted to the desired contour of the side reflector in such a way that they rest on the back of each side reflector and press them against stops which are formed on the one hand by the steps 313 in the edge strips and on the other hand by the end edges 30 of the transverse slats 3 .
  • the lower spring tabs 316, 317 hold the edge profile 12 of the side reflector 1 against the end edge 30 and the upper spring tabs 314, 315 hold the tongue 111 against the step 313 (FIG. 3).
  • the transverse slats are simply inserted into the openings 11 until their end edges 30 strike the profile edge 12; when inserting, the legs 31 of the transverse lamellae are initially pressed somewhat inwards by the spring tabs; in the end position, however, they spring back and the spring tabs get caught behind the back of the side reflectors.
  • the insertion of the transverse slats into the openings 11 is facilitated by the constant decrease in the width of the edge strips in the edge area of the transverse slats (FIG. 3).
  • V-shaped cross section is to be understood as any two-leg arrangement in which the distance between the legs is greater in the area of the upper free leg ends than in the connecting area of the legs.
