Definitions

  • the invention relates to a suspended ceiling with bandraster forming longitudinal and transverse bandraster elements and plate elements, bandraster elements being fastened to the building ceiling at a distance from the ceiling and the plate elements resting on the bandraster elements by means of end edges which are angled outwards.
  • Such a suspended ceiling consists of a bandraster with bandraster elements running through in one direction, which are fastened to the building ceiling, and bandraster elements running transversely thereto, which are held on the continuous bandraster elements.
  • Plate elements are inserted into the band grid formed in this way.
  • the plate elements like the bandraster elements, are cassette-shaped and certainly have outwardly angled support edges on two opposite end faces which can be placed on the flanges of the transverse or slow-running bandraster elements.
  • the long sides of the plate elements are free from support edges that are angled outwards.
  • the object of the invention is to provide a false ceiling of the type mentioned, in which in particular large plate elements can be easily installed and removed without damage, without having to be completely removed from the false ceiling.
  • This object is achieved according to the invention by a folding mechanism for the plate elements, which has effective guiding means between bandraster elements and plate elements.
  • the folding mechanism according to the invention With the help of the folding mechanism according to the invention, a precise and torsion-free insertion or folding, in particular of large plate elements, is possible. Furthermore, damage-free handling when hanging and folding the plate elements is guaranteed. This means that access to the ceiling cavity is easy and convenient. If necessary, the plate elements can also be completely removed and replaced with new ones.
  • a mounting false ceiling in which ceiling panels are fastened one behind the other between parallel to the raw ceiling Support rails are arranged.
  • Each ceiling panel has at its one end in the longitudinal direction a type of bracket that engages over the support rails.
  • At the other end of the ceiling panel there are locking elements in the form of clip or magnetic locks to secure the individual ceiling panels to the mounting ceiling.
  • the folded ceiling elements can swivel out and be moved on the support profile rails.
  • the folding mechanism is unsuitable for ceilings of the generic type.
  • EP-OS 0 204 024 describes and illustrates a coffered ceiling in which mounting rails are fastened to the bare ceiling via suspension elements. Cassettes can be snapped into place between the mounting rails designed as locking bars.
  • the latched side legs of the cassettes have recesses which, according to a special embodiment, can be L-shaped, into which expandable spring legs of the suspension element designed as a spring element engage.
  • the assembly of such a cassette ceiling is difficult because the resilient suspension elements can only be placed with difficulty on the mounting rails and at the same time have to engage in the recesses of the cassettes.
  • the guide means have at least one guide template with a guide contour and at least one pin for engaging in the guide contour. In this way, precise guidance of the plate elements during insertion and folding is ensured with simple means.
  • a plate element is particularly easy to install or remove without the risk of canting and / or damage if the guide contour has an essentially vertical guide slot.
  • the length of the guide slot should correspond at least to the greatest height of the adjacent bandraster element.
  • a particularly secure guidance of the plate element when inserting and unfolding is achieved if the guide slot receives the pin transversely to the slot direction with little play, so that when a plate element is installed or removed, only a movement in the vertical direction of the guide slot, but not in the horizontal direction is possible.
  • a plate element can be moved vertically along the guide slot and horizontal displacement along the cross slot from the bandraster without tilting and without the risk of damage to adjacent bandraster elements.
  • the transverse slot is expediently delimited on one side by a stop, by means of which the guide path in order to fold down a plate element is defined. After moving the pin up to the stop, the plate element can be folded down without the risk of the rear end of the plate element striking a bandraster element when it is folded down.
  • the transverse slot on the side opposite the stop or the guide slot opens into an insertion / removal opening in order to be able to disengage the pin from the guide contour of the guide template.
  • the guide slot or the transverse slot is angled in front of the insertion / removal opening by means of at least one projection, an accidental disengagement of the pin from the guide contour and thus an unintentional removal when a plate element is folded down is prevented.
  • the pin is round or polygonal in cross-section, preferably square.
  • a folded-off plate element is fixed by contacting the pin surfaces on the guide contour, so that a swinging back and forth of the folded plate elements is avoided.
  • the width of the transverse slot corresponds at least to the diameter or the longest cross-sectional diagonal of the pin.
  • a slope extends from the stop of the transverse slot into the guide slot, so that a plate element with its pins is gradually guided back into the guide slot when folded down due to its own weight.
  • a folding mechanism for a plate element expediently has two guide templates and two pins, which are each arranged on substantially opposite longitudinal sides of the plate element on the adjacent band grid elements or on the plate elements.
  • the guide templates are attached to a band grid element and the pin to the plate element.
  • Such an arrangement is particularly useful so that the plate elements can be stacked freely before and after complete installation or removal.
  • the guide means have at least one swivel bracket which allows a translatory and a rotary movement relative to the bandraster, which connects the plate element and a bandraster element adjacent to the plate element.
  • a swivel bracket also allows a defined and precise folding down and a similar installation of a folded plate element.
  • a suspended ceiling which consists of locking beams and cassette-like ceiling panels running in parallel, the ceiling panels being held in the locking beams by means of locking projections on the raised flanges.
  • the ceiling elements can be moved along the mounting rails via the brackets, but they can also butt against one another and therefore be damaged. A defined position of the ceiling element when folded down and during installation is difficult to achieve due to the movability.
  • the swivel bracket is approximately S-shaped in plan view, preferably with an elongated connecting section and two fastening sections angled therefrom.
  • the swivel bracket can then perform a translatory and a rotary movement in a particularly simple manner if a fastening section is rotatably and essentially horizontally displaceably mounted on a bandraster element or a plate element.
  • an exact and defined horizontal movement of the swivel bracket is achieved in that one fastening section is mounted in a fastening tab with a horizontal slot.
  • the slot receives the one fastening section with little play transversely to the slot direction.
  • the other fastening section is only rotatably mounted on the plate element or a bandraster element.
  • the plate element can also be completely and easily removed from the false ceiling, for example in the case of a damaged and exchangeable plate element.
  • the free end of the latching tab has a chamfer on the opening side, so that the other fastening section can be inserted into the latching tab without problems.
  • the connecting section of the swivel bracket in the folded and / or installed position of the plate element is preferably at least partially on the top of a flange of the adjacent band grid element.
  • the false ceiling according to the invention has a device which prevents the plate element from tipping over in the unfolded position, for example when the swivel bracket is standing vertically .
  • a fastening section of the swivel bracket is mounted on the top of the flange of a bandraster element adjacent to the plate element for this purpose.
  • the swivel bracket preferably has a bracket section which engages under or overlaps the flange and strikes the flange in the open position of the plate element, for example when the swivel bracket is in a vertical position. In this way, a tipping over of a plate element is effectively prevented.
  • the bracket section expediently adjoins the fastening section mounted on the flange and is angled therefrom.
  • the bracket and fastening section can thus be made from a single piece.
  • the bracket section has an angled stop that engages under the flange.
  • a folding mechanism for a plate element also has two swivel brackets in this embodiment, which are each arranged on essentially opposite longitudinal sides of the plate element.
  • the latching tab is attached to the top of an inwardly angled flange of the plate element and the fastening tab is attached to the top of the flange of the adjacent band grid element, so that the swivel bracket remains on the flanges of the band grid elements of the band grid when a plate element is removed .
  • a plate element can be folded down easily and without problems if the folding mechanism is arranged in the region of the side wall of the plate element which does not have an outwardly angled support edge.
  • a plate element can simply be folded down and remains in the folded position due to its own weight.
  • the invention can also be implemented if the folding mechanism is rotated horizontally by 90 °, that is to say between the longitudinal bandraster profiles and the correspondingly equipped plate elements are arranged or integrated in a node band grid. Furthermore, the corresponding guide elements of the plate element and bandraster profiles can also be interchanged in pairs if required.
  • the folding mechanism according to the invention is evidently not limited to the specifically described shape of the plate elements.
  • the suspended ceiling 1 shown in FIGS. 1 to 6 has bandraster profiles 6 running parallel and at a distance from one another, which are fastened to a building ceiling by means of hangers H distributed over their length.
  • Side walls 10 of the longitudinal bandraster profiles 6 are provided with flanges 8 angled inwards.
  • similarly formed but short bandraster profiles 4 run which are carried by the longitudinal bandraster arrows 6; the transversely running bandraster profiles 4 can also be held on the building ceiling by means of hangers H in the case of large spans.
  • Flanges are angled outward from the end walls of the transversely running bandraster profiles 4, which lie on the inwardly angled flanges 8 of the longitudinally running bandraster profiles 6 and are fastened there if necessary.
  • a number of band grid fields are formed by the transverse and longitudinal band grid profiles 4, 6.
  • the individual band grid fields are plate elements 2, the side walls 20 of which are inwardly angled flanges 3 and whose end walls 12, 14 have outwardly angled support edges 16, 18 with which the plate elements 2 rest on the flanges 8 of the longitudinally running bandraster profiles 6.
  • the plate elements 2 and thus also the folding mechanism can be arranged rotated by 90 ° in the horizontal, so that the plate elements 2 with their support edges 16, 18 are carried by the transverse bandraster profiles 4 and the guide means of the folding mechanism are the longitudinal ones Bandraster profiles are assigned.
  • the folding mechanisms can also be integrated into the node elements.
  • a folding mechanism for a plate element 2 has two guide templates 30 as guide means, each of which is arranged on opposite sides of a plate element 2 on the adjacent transverse bandraster profiles 4.
  • a guide template which is angled in the lower region is in each case on the upper flange 8 of the transversely running bandraster profile 4 30 attached.
  • the guide screw block 30 has a guide contour 32, in each of which a pin 52 engages on corresponding mutually opposite side edges, which are free of the support edges 16, 18 and which are fastened to the plate element 2, with little play.
  • the guide contour 32 has a substantially vertically running guide slot 34, the length of which corresponds at least to the greatest height H of the plate element 2.
  • the guide slot 34 merges upwards via a bevel 42 into an approximately horizontally extending transverse slot 35, the transverse slot 35 pointing in the direction of the adjacent longitudinally extending bandraster profile 6.
  • the length of the transverse slot 35 is selected such that, depending on the width of the support edge 16 of the plate element 2 which is further away, the support edge 16 is released from the adjacent longitudinal bandraster profile 6 when it is folded down.
  • the transverse slot 35 is delimited by a stop 36 in the direction of the closer longitudinal band locking profile 6.
  • An opening slot 40 leading upwards is provided at the end of the transverse slot 35 opposite the stop 36.
  • a projection 38 is provided for angling the transverse slot 35, which prevents the pin 52 from slipping out unintentionally.
  • a pin 52 is attached on opposite sides to engage the guide contours 32 of the guide templates 30 via a fastening tab 50.
  • the pins 52 inserted through the guide contour 32 are, as can be seen from FIG. 7, each secured by a snap ring 54 or the like placed on its free end.
  • a plate element 2 To fold a plate element 2 out of its installation position shown in FIG. 2, it is first raised in the direction of arrow A (see FIG. 3) in the vertical direction. Tilting or abutting the end walls 12, 14, 20 of the plate element 2 against the band grid profiles 4, 6 is avoided due to the guide of the pins 52 in the guide slots 34. After the pins 52 have struck the upper edge of the transverse slots 35, the plate element 2 is moved horizontally in the direction of arrow B (see FIG. 4) until the pins 52 arrive at the stop 36 of the transverse slot 35. Then, at the latest, the end of the plate element 2 facing away from the folding mechanism can be folded out in the direction of arrow E (see FIGS.
  • the plate element 2 is then moved with its pins 52 in the direction of the opening slot 40 until the pins 52 strike the projection 38.
  • the plate element 2 is then raised again in the direction of arrow A and can then be removed from the guide template 30 upwards.
  • FIG. 7 to 11 a further embodiment of the invention is shown.
  • the band grid shown in FIG. 7 for a false ceiling 1 essentially corresponds to that shown in FIG. 1.
  • the lower ceilings 1 of FIG. 7 differ from the lower ceiling 1 according to FIG. 1 only in the design of the guide elements of the folding mechanism for the plate elements 2.
  • the folding mechanism shown in FIG. 7 is shown in more detail in FIGS. 8 to 11.
  • the folding mechanism for the plate element 2 in this case has two swivel brackets 60 which are arranged on opposite sides of the plate element 2 adjacent to one end of the transversely running bandraster profiles 4.
  • the swivel bracket 60 as can be seen in FIG. 11, is approximately S-shaped in plan view and has an elongated connecting section 68 and two fastening sections 70, 72 bent approximately at right angles therefrom.
  • the fastening section 72 is rotatably and horizontally displaceably received in the horizontal slot 64 formed by a fastening tab 62.
  • the fastening tab 62 is fastened with its ends to the top of the flange 8 of the adjacent transverse bandraster profile 4.
  • the fastening section 70 is rotatably, but non-displaceably, releasably clamped to the plate element 2 via a latching tab 66 fastened on the flange 3 of the plate element 2.
  • the length 1 of the slot 64 is dependent on the length of the connecting section 68, the height h of the plate element 2 and the width of the support edge 18 such that tilt-free folding or removal of a plate element 2 is ensured, as can be seen from the mode of operation described below results closer.
  • the latching tab 66 fastened on the flange 3 of the plate element 2 takes the fastening section 70 in place Condition rotatable but otherwise practically free of play.
  • the latching tab 66 rests on the opening 3 on the flange 3 with a flat support section 80.
  • An opening-side bevel 78 adjoins the support section 80 in order to facilitate the insertion of the pin 70 under the latching tab 66.
  • the fastening section 72 of the swivel bracket 60 is followed by a bracket section 74 angled therefrom (cf. FIG. 11), which engages around the flange 8 of the bandraster element 4.
  • a stop 76 which engages under the flange 8, adjoins the bracket section 74.
  • the plate element 2 is to be completely removed from the bandraster in this exemplary embodiment, it is first moved in the direction of arrow A, as shown in broken lines in FIG. 10, until the fastening section 70 disengages from the latching tab 66. The plate element 2 is then moved in the direction of arrow B and can be removed from the bandraster in direction C.
  • the reverse procedure is used to insert and fold a plate element 2 into a band grid.
  • the plate element 2 is brought into the vertical position in the position shown in dashed lines in FIG. 10, so that the fastening section 70 abuts the flange 3 of the plate element 2.
  • the plate element 2 is then moved downwards in the vertical direction in the direction of arrow C, so that the fastening section 70 is caught by the bevel 78 of the latching tab 66 until the fastening section 70 engages under the bulge of the latching tab 66.
  • the procedure is then reversed in accordance with the procedure illustrated for the folding.
