Definitions

  • the invention relates to a detachable grid ceiling made of intersecting web elements which engage at the intersection points with corresponding recesses which are provided in opposite directions over approximately half the web height and are arranged in grid dimensions and which, in comparison with the web dimensions, enclose large web-free surfaces and can be moved along the webs Suspension devices are equipped.
  • the known grid ceilings of the aforementioned type consist of web elements which are produced as strips from chipboard and which have a coating of plastic or a film lamination.
  • the recesses provided at the crossing points are generally introduced into the web elements after the strips made of the chipboard have been laminated.
  • Suspendable grid ceilings consisting of such web elements find a particularly versatile application in exhibition and sales rooms and lead in connection with lighting devices arranged at the height of the grid ceilings to a visual reduction of the respective room height, whereby the space remaining above the grid ceiling can remain in the unfinished state and only needs to be given a dark coat of paint in order not to appear visibly.
  • the known suspended grid ceilings are relatively heavy due to the production of the web elements from chipboard and therefore require stable suspension devices or a large number of relatively closely adjacent suspension devices. These usually consist of two wires or rods, one of which is attached to the web element and the other to the building ceiling and the free ends of which are held overlapping one another in resilient clamping elements, with the aid of which the exact height of the grid ceiling and the height alignment are maintained the web elements can be made.
  • the upper edges of the web elements which are in the suspended state of the grid ceiling, are equipped with opposing grooves into which slidable brackets engage, to which the lower ends of the wires or rods of the suspension devices are fastened.
  • the crossing web elements are fixed by clamps which are driven into the upright sides pointing upwards when the ceiling is suspended. If such grid ceilings are arranged in the entrance area of sales rooms or the like, an additional optical covering of the free surfaces enclosed by the web elements, for example by means of fabric sheets or by means of foils or cover plates, is often desired. These sheets or plates intended for covering are also fastened to the webs by clips.
  • the object of the invention is to remedy this situation and to design a suspended grid ceiling of the type described in the introduction in such a way that it has a high level of safety against breakage on insensitive surfaces of the web elements with a low weight and leads to considerable simplifications in the assembly and disassembly, so that a safe reusability is made possible.
  • the detachable grid ceiling of the type described in the introduction is characterized in that the web elements are designed as hollow-chamber profiles made of plastic with chambers extending in their longitudinal direction, and that at least one of the two upright sides of the web elements is at least partially slit in the longitudinal direction and is snap-like or hook-shaped engagement of molded parts of holding or supporting members or cover plates in the respective edge-side chamber is provided.
  • the web elements can only be provided on one upright side with the slit mentioned, in such a way that this slotted upright side of each web element points upwards in the suspended position of the ceiling. Because the molded parts of the suspension device engage from the upright side in the individual web elements, the suspension elements, such as rods or wires, appear less visibly than is the case with the known grid ceilings. In the new design, no additional profiling of the side walls and clamps which can be moved in these profilings are required, which, in addition to the technical complexity, are perceived as annoying due to their visibility.
  • slots are arranged in the two upright sides of the individual web elements, there is the possibility of also using the slots pointing downward when the ceiling is suspended for fastening elements or supporting devices which can be suspended therein.
  • fastening elements or supporting devices which can be suspended therein.
  • hooks or snap-in engaging molded parts such as carrying brackets or the like, can be provided in these slots for the hanging fastening of information signs, price boards, etc.
  • the slots can be arranged in rows in the upright sides mentioned in the longitudinal direction. In terms of their width, they are each smaller than it corresponds to the web width, so that laterally, in addition to the webs, there are still upright wall surfaces, which serve as abutment surfaces for the snap-in or hook-shaped molded parts in webs milled into this wall.
  • At least one of the two upright sides of the web elements is continuously slotted and the slot is delimited by longitudinal edges of the walls of the associated chamber which point inward in the manner of a hook.
  • the molded parts engaging in the slot can be inserted at any point on the upright side and can also be displaced along the slot.
  • the inward-facing longitudinal edges stabilize the side walls of the respective chambers and also act as suspension elements for the molded parts that can be inserted into the slot.
  • the longitudinal edges of the edge-side chamber (s) of the web elements which point inward in the shape of a hook, run parallel to the associated side walls of the chambers and enclose with them a gap which is open towards the interior of the chamber.
  • this design has the very great advantage that the hook-shaped inward-facing longitudinal edges can be used to engage hook-shaped or anchor-shaped molded parts, for example the suspension devices or the like, by leaving the gap with the side walls of the associated chambers.
  • the molded parts engaging in the respective chamber are designed like hammerheads and are held on a free end of a rod or flexible support part.
  • This design of the molded parts is suitable for all slot designs described in the or the upright sides of the support elements.
  • the width of the hammer head-like molded parts is dimensioned approximately in accordance with the slot width, so that the molded parts can be inserted without difficulty into the chambers provided with the slots and can be transferred into the supporting or supporting position by twisting by 90 °, with appropriate dimensioning or
  • the mutual attachment of the web elements at the crossing points is expediently carried out in such a way that the crossing points are covered by bridge members which have a plate corresponding to the web width with molded parts projecting therefrom, which on both sides of the KrQEungsstelle snap-in insertable into the slot of the web element interrupted at the crossing point are held.
  • bridge members can, since they are also attached by the push button principle, without Remove difficulties during disassembly and use when reassembling the grid ceiling without causing any damage to the bridge members or the web elements.
  • the side walls of the web elements can be made smooth or profiled in the usual way. Since the web elements are generally produced as drawn components, it is possible without difficulty to provide beads or grooves running in the longitudinal direction, for example, in the side walls of the web elements if the smooth-walled design is not desired.
  • the drawing shows an embodiment of the invention.
  • the partial top view of the grid ceiling shown in FIG. 1 shows web elements 1 running in one direction and web elements 2 running perpendicularly thereto.
  • the web elements 1 and 2, of which a view is shown in FIG. 2, point in opposite directions about the half the web height provided and arranged in the grid dimensions of recesses 4 with which they interlock at the intersection points.
  • the web elements 1 and 2 enclose square web-free surfaces 5, which are kept very large compared to the web dimensions.
  • the web elements 1 and 2 are designed as hollow chamber profiles 6, as can be seen particularly clearly from FIGS. 3 and 3a. They have hollow chambers 6a running in the longitudinal direction and are designed as plastic profiles which, in the form shown, can be extruded in great lengths.
  • this is an upright side, i.e. the edging-side boundary wall of the one edge-side chamber 6b is provided with a slot 7 running along the central longitudinal plane, which is designed in a special way in this example.
  • the slot 7 extends to a relatively deep depth into the edge-side chamber 6b and is delimited by hook-shaped longitudinal edges 8 pointing inwards or downwards. Between these downward-pointing longitudinal edges 8, which run parallel to the side walls of the edge-side chamber 6b, gaps 9 which are open towards the bottom can be seen.
  • the gap 7 is used for snap-like or hook-shaped engagement of molded parts, for example the suspension devices or other support members, and also cover plates which may be provided.
  • FIG. 3a shows, for example, the arrangement of a suspension device held in the slot 7.
  • This consists of a hammer head-shaped part 10, which is attached to the free end of a rod or flexible support member 11.
  • the hammer head-like molded part 10 which is also clearly shown in FIG. 4, is equipped with upstanding web-shaped projections 12 which engage in the gap 9 of the chamber profile parts 6 in the suspended position of the ceiling, as can be seen particularly clearly from FIG. 3a . Due to the hammer-head like configuration of the shaped part 10 of this can be inserted with a width which corresponds approximately to the slot width 7 in the edge-side chamber 6b and brought to rotation by 90 0 with the upstanding ridge-like projections 12 in the slots 9 in engagement.
  • the dimensions of the rod or flexible support member 11 are dimensioned so that the slot 7 is filled by this support member or rod.
  • the upstanding web-shaped projections 12 there is a positive engagement of these web-shaped projections 12 in the column 9, so that the inward-pointing longitudinal edges 8 are held in a clamped manner between said web-shaped projections 12 and the rod or flexible supporting part 11.
  • Such connection can be subjected to very high loads without the risk of deformation of the hook-shaped inward longitudinal edges 8 or the side walls of the edge-side chamber 6b.
  • the hammer head-like molded part 10 can be formed in one piece with the upstanding webs 12 and made of plastic.
  • 5 to 7 show the formation of an intersection.
  • 5 shows the intersection Y marked by a circle in FIG. 1, at which the web elements 1 and 2 with their recesses 4 overlap one another.
  • the web element 2 is provided with a recess 4 in its lower region, while the web element 1 has this recess 4 in its upper part, that is to say the part provided with the slot 7 on the edge.
  • the crossing point is covered along the web element 1 by a bridge member 13, which consists of a plate 13a and molded molded parts 13b formed thereon, with which the plate is made in one piece.
  • These molded parts 13b are mushroom-like or, at their free ends, are provided with heads 13c which serve for snap-like engagement in the edge-side chamber 6b of the associated hollow chamber profile 6 or the corresponding web element 1 or 2.
  • FIG. 1 Similar to the attachment of the bridge members 13, cover or mounting plates can be attached to the web elements 1 and 2.
  • FIG. 1 which is shown enlarged in FIGS. 8 and 9, shows such a mounting plate 14, which is provided on its underside with the same molded parts as the bridge member 13. It can be seen from FIGS. 8 and 9 the molded parts 13b, which have heads 13c at their free ends.
  • the mounting plate 14 can be used, for example, for fastening electrical installation elements, such as sockets or the like.
  • the entire web-free areas 5 between the web elements 1 and 2 can also be covered in the same way over a predetermined area of the suspended grid ceiling.
  • slot recess can be provided in the upright wall of the web elements, as indicated at 15 in the lower part of FIGS. 3 and 3a.
  • slots 15, which are provided as pure recesses, require interruptions on the length of the web elements for reasons of stability and are less heavy-duty than the above-described configuration of slot 7. Because of the necessary interruptions in slots 15, it is also not possible to insert holding devices inserted into the slots to move in any way along the web elements 1 or 2; However, even with the arrangement of slots 15, the hook-shaped or snap-like engagement of molded parts is possible in the same way as was described in connection with slot 7.
  • the embodiment shown in the figures shows that the suspended ceiling is very simple and easy to assemble and can also be suspended and dismantled without any risk of damage, the web elements 1 and 2 being able to be produced in much greater length without hesitation by using the hollow body profiles than is possible with the materials previously used.
