Definitions

  • the invention relates to a lattice-like false ceiling with parallel support rails, these cross-members at intervals connecting them and with grid plates inserted into the fields thus formed between support rails and cross-members, which are formed by upright, crossing, cross-sectionally approximately V or U-shaped lattice bars. the walls of which diverge from their underside upwards.
  • each grid plate must be attached to two mounting rails and / or trusses in order to ensure a safe suspension.
  • the stripes of the individual grid plates are located outside the course of the mounting rails, so that under certain circumstances the underside level of such a suspended ceiling can become irregular.
  • the solution to this problem essentially consists in the fact that on the mounting rails and / or the traverses these downward-covering individual webs with the same U- or V-shaped, optionally concave or parabolic curved cross-section of the lattice webs run at least in the area of the fastening points of the Transversely to the support rails and / or the crossbars on the individual webs, the free ends of the crossbars engage spacers between the walls of these individual crosspieces and that at the free end of at least one of the ones that run towards the support rails, possibly also those on crossbars or crossbars from adjacent grid plates Lattice webs a hanger and also at least one spacer is arranged between the walls.
  • the grid plates each meet webs at their edges, the appearance of which corresponds to the webs of the grid plate, so that the overall ceiling receives a closed appearance. Nevertheless, all the grid plates can have freely ending grid webs on the sides.
  • the deformation of the web walls by the suspension forces or the like is prevented by the engaging spacer as well as the deformation of the individual webs in the area of impact of the lattice webs. This prevents the formation of joints even with parabolically curved end faces and cross sections of the webs.
  • the spacer is arranged at the end of the lattice web in the upper edge area of its walls. There these walls have the greatest distance, so that the inner support effect of the spacer comes into effect best.
  • a suspension hook preferably pivotable over the mounting rail or crossbar, can be provided as the suspension.
  • Swiveling hooks for hanging grid plates are known per se. In the present case, however, a corresponding ver Longer hook required to be able to reach over the mounting rail or crossbar because it starts from the lower level of the lattice and single webs.
  • An embodiment of the invention of very considerable importance which simplifies the overall production and handling, can consist in that the spacer for the free ends of the crossbars is at the same time the pivot axis of the suspension hook.
  • the spacer for the free ends of the crossbars is at the same time the pivot axis of the suspension hook.
  • the spacer has protrusions which protrude on both sides and have a reduced cross section with respect to them, which engage in perforations in the walls of the lattice webs, which perforations are exceeded or surpassed by the cross section of the spacer.
  • the spacer with the hanging hook located thereon can be pivoted about these pins, while still performing its spacing function at the edges of the perforations mentioned.
  • the hook part of the suspension hook located outside the spacer can be narrower on one side than the spacer part, in particular at least half narrower. This makes it possible to have the suspension hooks from two sides of a grid or a crossbar hitting each other on these beams or crossbars so that the grid webs connected on both sides to a rail run in alignment and each grid plate can still be individually dismantled . This advantageously results in the fact that, in order to dismantle the suspension hooks, they can be pivoted into the open position and then the grille are lowerable so that it does not have to be raised for this disassembly.
  • Embodiments of the suspension hook and the spacer connected to it as well as the pivot axis are the subject of claims 7 and 9 to 11.
  • the upper edges of the walls of the individual web have locking lugs protruding inwards at intervals, which fit over the outwardly facing flanges of the support profile. It is expedient if the individual webs, which have a greater length than the distance between two cross members, have lateral notches on their edges at a distance from the cross members starting from the beams. This prevents the trusses from coming off the beams by means of these individual webs which are clipped onto the flanges of the beams from below.
  • the grid plates 4 are in turn formed by upright, intersecting, cross-sectionally U-shaped grid webs 5, the walls 6 of which - as indicated in FIG. 2 - diverge from their underside 7 upwards.
  • Fig. 1 and 3 it is shown that on the support rails 2 and the trusses 3 these down-covering individual webs 8, which have the same U-shaped cross section as the lattice webs 5, so that this cross-section is particularly clearly shown in Fig. 3 recognizes in which the walls 6 of these individual webs also run from the underside 7, whereby they also have a concave curved shape, for example a prabolic shape.
  • FIG. 2 the free end of a single web 5 of a grid plate 4 can be seen, the end faces 9 seen in the side has the same contour as the wall 6 of the single web 8 in order to be able to abut this web 8 without a joint, as shown in FIG Fig. 1 is shown.
  • Such an oblique or even curved end face 9 would, however, change its lateral shape if the spacings of the walls 6 change due to forces occurring on them. Such forces can be caused simply when gripping the webs 5 during assembly or also caused by suspension forces acting on the walls 6. The same applies to the walls 6 of the individual webs 8, which would also form 5 joints at the abutment points with the lattice webs in the event of deformation by changing their distance.
  • this is prevented by the fact that at least in the area of the joints where the grid webs 5 meet the individual webs 8, spacers 10 engage between the walls 6 of the individual webs 8 and that at least one spacer 11 between the walls of the web webs 5 is also at their free ends Walls 6 is arranged. Furthermore, a hanger is also arranged in this end region of the lattice webs 5, which in the exemplary embodiment according to FIGS. 1 and 2 is a swiveling suspension hook 12 which crosses over the mounting rail 2 or crossbar 3.
  • the spacer 11 at the end of the grid web 5 is arranged in the upper edge region of its walls 6, where the risk of lateral deformation of these walls 6 is greatest.
  • the spacers 10 and 11 prevent deformation of the walls 6 of the webs 5 and 8, so that even under unfavorable conditions these webs can no longer be deformed in such a way that their joint receives joints, even when they are made from relatively thin sheet metal. even if the relatively complicated parabolic cross-sectional shape is chosen, which is often desired for optical reasons.
  • the spacer 11 for the free end of the grid webs 5 simultaneously forms the pivot axis of the suspension hook 12.
  • the spacer 11 on both sides has protruding pins 13 with a reduced cross section relative to it, which engage in perforations 14 in the walls 6 of the lattice webs 5, these perforations 14 on the inside of the walls 6 being protruded by the cross section of the spacer 11.
  • the spacing function at the edges of the perforations 14 is retained at all times.
  • two different parts are not required to fix the spacing of the walls 6 and to mount the suspension hook 12.
  • hook 12, spacer 11 and pivot axis are connected in one piece and punched out of sheet metal, for example.
  • the pins 13 serving as the pivot axis are designed as tab-shaped projections which protrude from the spacer 11 of the hook 12 at its end facing away from its hook opening. To insert them into the perforations 14, the relatively flexible walls 6 need only be bent apart slightly, after which they return to their original position due to their inherent tension and now overlap the pins 13.
  • the hook 12 has two hook-in bends 15 and 16 which follow one another in the pivoting direction, in order first to be able to carry out a provisional and then a final fixation or to be able to loosen a grid plate 4 when disassembling without it being completely detached from the composite. Since the hooks 12 consist of flat sheet metal, two such hooks 12 can overlap two grid plates 4 located opposite one another on a support 2 or a cross member 3. In this case, however, these grid plates 4 must then be unhooked one after the other.
  • the hook part located outside the spacer 11 is narrower on one side by at least half compared to the spacer 11 is, so that hooks can now lie side by side on a support 2 or a crossmember 3, while the lattice webs 5 of these neighboring plates 4 connected to them are nevertheless aligned with one another.
  • the hook 12 extends approximately at right angles from the spacer part 11, its pivot axis 13 is moved such that no lifting of the grid plate 4 is required when dismantling. Rather, it is sufficient to simply pivot the suspension hook 12 into the open position and then lower the grid plate downward. Since the hook starts from a point arranged at a distance from its pivot axis, the hook openings 15 and 16 describe circular arcs which rise somewhat from their release position and which enable the aforementioned suspension without lifting the grid plates 4.
  • the individual webs 8 extend over their entire length over a part 17 of the profile of the support 2 or the cross member 3, so that this engaging area or part 17 of the support profile provides a continuous spacer for forms the respective individual web 8. This not only improves the attachment to the support profile, but also increases the stability over the entire length of the individual web 8. Deformations of the walls 6 are virtually excluded, so that no joints at the joints with the individual webs 5 of the grid plates 4 are to be feared.
  • the upper edges of the walls 6 of the individual web 8 have locking lugs 18 which project inwards at intervals and which fit over outward-facing flanges 17 of the supporting profile. This can easily be done by slightly bending the walls 6 apart be brought into their position of use. This results in a very easy assembly not only of the grid plates 4, but also of the individual webs 8 that terminate these at the edges, the presence of which can reduce the number of beams 2 and trusses 3 required to hold the grid plates 4, since there are two for each plate 4 a beam or a traverse is sufficient. This is made possible by the unusual combination of spacers between the walls of the webs and the use of individual webs in each case as the edge closure of the grid plates in the manner described.
  • FIGS. 4 and 5 show two exemplary embodiments in which the false ceiling 1 has no cross members 3, but rather the grid plates 4 are only inserted between parallel mounting rails 2.
  • the same reference numbers are used for the same parts as in the exemplary embodiment described above according to FIGS. 1-3, and parts that are no longer described are designed in the same way as in this exemplary embodiment according to FIGS. 1-3.
  • the grid webs 5a running parallel to the mounting rails 2 next to one another in the use position end alternately at a grid web 5 arranged transversely to the mounting rails 2 or approximately by the clear dimension A of one enclosed by the grid webs 5 Extend the grid field in the direction of the mounting rail.
  • the respective projecting lattice web 5 then abuts with its free end against the closest transverse lattice web 5 of the adjacent lattice plate 4, which practically forms a kind of traverse, which is no longer shown in FIG. 4 for the sake of simplicity. This can be continued on both sides be set as the mounting rails 2 are sufficient.
  • Fig. 5 it is provided that all in the use position parallel to the support rails 2 side by side crossbars 5 a by a fraction, in the embodiment, about half the dimension A of a grid field over a transverse crossbar 5 and blunt against the end faces of the corresponding crossbars 5 a of an adjacent grid plate 4 encounter. Even in this way, a closed appearance of the grid plate can be achieved between parallel support rails 2 with the aid of the individual webs 8 on these support rails 2, deformations in the area of the suspension hooks 12 being avoided by the spacers 11.
