False ceiling

Abstract

The invention relates to a suspended ceiling which comprises ceiling elements (1) and supporting profiles (2, 3, 16, 23, 27, 38, 44), - wherein pairs (10, 13) of stop surfaces block relative movement of the ceiling element (1) horizontally normal to the supporting profiles, - wherein the pairs of stop surfaces can be disengaged by an upward movement of the ceiling element (1), - wherein a displacement region (15) extends in the horizontal direction on one of the supporting profiles, into which displacement region the ceiling element (1) can be displaced in the horizontal direction towards the respective supporting profile (2, 16, 23, 27, 38, 44). The wall-side support profile (2, 16, 23, 27, 38, 44) has a profile wall (14, 18, 29, 39) projecting in the horizontal direction, which extends below the underside of the flat element (5, 19) and thus represents a visual screen for an edge region of the flat element (5, 19), whereby the flat element (5, 19) is particularly easy to shorten.

Description

[0001] The invention relates to a suspended ceiling which comprises ceiling elements and supporting profiles supporting the ceiling elements.

[0002] A suspended ceiling generally comprises ceiling elements and supporting profiles, which serve to transfer the weight of the ceiling elements to other parts of the building. Typically, a ceiling element covers a horizontal, often very elongated, rectangular area. Ceiling elements are often profiles made of metal or wood. Sometimes, however, ceiling elements are also panels or plates made of sheet metal (a large, flat surface with raised edges), wood, or a composite material, which may include, for example, plasterboard.

[0003] For example, KR 20190064814 shows a suspended ceiling in which the supporting profiles have a horizontally aligned profile wall, on which ceiling elements rest from above with a strip-shaped edge area of their underside. If a ceiling element is moved horizontally and transversely to the longitudinal direction of such a strip-shaped edge area towards the supporting profile on which this edge area rests, until the ceiling element abuts with one end face against a vertical surface of the supporting profile, an opposite strip-shaped edge area of the ceiling element must still rest securely on a surface of an opposite supporting profile. Otherwise, there would be a risk that the ceiling element would fall down on its own after several vibrations.This design rule requires that, in the event of necessary dismantling – for example, to access cables located above the suspended ceiling in the so-called ceiling void – a ceiling element must be lifted very high on one side so that it can then be removed downwards with the other side facing forward. This means that the suspended ceiling requires a comparatively high ceiling void above it. A key advantage of this construction method is that, if necessary, ceiling elements can be shortened on site simply by trimming away an edge. This is because cutting inaccuracies and unsightly surface areas on and at the cut surface are concealed by the supporting profiles after installation and thus do not visually disrupt the design.

[0004] DE 10108135 C1 shows a suspended ceiling for aisle ceilings on ships. A single ceiling element extends across the entire width of the aisle to be covered, with the exception of two edge gaps. Two supporting profiles run horizontally along the aisle, each on a wall at the height of the suspended ceiling. In addition to a flat panel, the ceiling element comprises two edge profiles, which rest against the upper side of the panel and are connected to it, and extend laterally beyond the panel into the area of the supporting profiles. The edge profiles and the supporting profiles are interlocked by a downwardly open profile hook on the edge profile protruding into an upwardly open profile hook on a supporting profile. This interlocking ensures that the ceiling element cannot slip sideways to the point where it falls down.Additionally, this means that the ceiling element only needs to be lifted as high as the hooks extend in the vertical direction during dismantling. Thirdly, one of the hooks between one of the edge profiles and the corresponding support profile can be designed in such a way that the ceiling element can hang from this hook even when the hook on the other side is unhooked and the ceiling element is pivoted into a vertical position. In technical terms, this means that the ceiling element can be folded down around its short side (which is aligned parallel to the two support profiles). A remaining disadvantage is that the ceiling elements cannot be shortened on site to the dimensions found there, because unsightly cut surfaces and edges of the cut surfaces remain visible even after installation.

[0005] US 10145104 B1 shows a suspended ceiling in which the ceiling elements are C-profiles arranged with a profile groove open at the top, and in which the supporting profiles are T-profiles arranged with a crossbeam underneath. The end regions of the C-profiles rest on the crossbeams of the T-profiles from above. In addition, an insertion part is inserted into the C-profile at each of the two front ends of a C-profile and anchored there by friction. The insertion part has a narrow hook that is open at the bottom and with which the central web of a supporting profile is gripped from above. This design ensures that the ceiling elements are held securely and allows ceiling elements (C-profiles) to be shortened on site by cutting them off.Disadvantages include the fact that the assembly, consisting of a C-profile and two inserts, must be precisely adjusted in length to the grid of the supporting profiles, thus requiring a very high empty ceiling cavity during assembly and disassembly. It is difficult to prevent the hooks on the supporting profile from colliding with other hooks and with the supporting profile brackets. The ceiling elements cannot be folded down. The document does not contain any information on how the supporting structure should be designed at the edge of the suspended ceiling.

[0006] The problem underlying the invention is to provide a construction method for a suspended ceiling in which the ceiling elements projecting to the edge of the suspended ceiling can be easily cut to the appropriate length at the installation site without compromising appearance, safety, or workload, and which does not require a high ceiling void. Optionally, it should also be possible to design the ceiling elements as hinged elements, so that they can be pivoted downwards around one of their side edges, and their weight is still supported by a supporting profile even when pivoted downwards.

[0007] To solve the problem, the combination of features from DE 10108135 C1 is adopted that the suspended ceiling consists of ceiling elements and supporting profiles, wherein a ceiling element comprises a flat element and a connecting element connected thereto, wherein a ceiling element is supported at two opposite edge regions against downward movement by a supporting profile running in a horizontal direction, one of the supporting profiles running along a wall laterally bordering the suspended ceiling, wherein, when the ceiling element is fully assembled, pairs of stop surfaces are present, each of which comprises a surface of the ceiling element and a surface of a part that is connected independently of the ceiling element to one of the supporting profiles, which jointly block relative movement of the ceiling element with respect to the supporting profiles in both directions that are horizontal and normal to the direction of the two supporting profiles,wherein the two stop surfaces of the pairs of stop surfaces can be disengaged by an upward movement of the ceiling element relative to the respective support profile, wherein at least on one of the two support profiles a displacement area extends in the horizontal direction, into which the ceiling element can be displaced in the horizontal direction towards the respective support profile after the stop surfaces of one of the pairs of stop surfaces have been disengaged by an upward movement of the ceiling element, ,

[0008] As a further development according to the invention, it is proposed that the support profile running along the wall has a profile wall projecting in a horizontal direction, which extends into the space below the underside of the flat element.

[0009] The combination of features according to the invention retains all the advantages of DE 10108135 C1 and achieves the significant additional benefit that the edge region of the planar element of the ceiling element facing the wall is not visible from below, which means that it is not a problem if the planar element has a cut surface at this edge region, which results from the fact that the planar element was shortened by cutting directly on the construction site for the purpose of uncomplicated adjustment of its length.

[0010] The invention, including advantageous optional further developments, is explained in more detail with reference to somewhat stylized drawings of several embodiments.

[0011] In the drawings and in the following description, parts which belong to different embodiments but have the same function are usually designated with the same position numbers.

[0012] Fig. 1 shows an exemplary suspended ceiling according to the invention, a ceiling element 1, which is supported on two opposite sides by a respective support profile 2, 3 against downward movement. The support profile 2, which is attached to a wall 4 laterally bordering the suspended ceiling and runs horizontally along it, is further referred to as the "wall-side support profile 2."

[0013] The ceiling element 1 comprises (among other things) a flat element 5 and a connecting element 6 connected to it. The flat element 5 extends over the entire distance between the two support profiles 2, 3. The connecting element 6 is connected to the flat element at that edge region 7 which runs along the wall-side support profile 2. The connecting element 6 protrudes horizontally over the edge of the flat element 5, normal to the direction of the support profile. At the protruding region, the connecting element has a downwardly projecting extension 8 which extends from above into a spatial area between the wall 4 and a vertically extending profile wall 9 which belongs to the wall-side support profile 2.The mutually facing surfaces of the part of the extension 8 projecting into said spatial area and the profile wall 9 extending in the vertical direction form a pair 10 of stop surfaces which positively block the sliding of the ceiling element 1 in the horizontal direction away from the wall-side support profile 2.

[0014] The part mentioned above, which is connected to the support profile 2 independently of the ceiling element 1 and has a surface which is part of one of those pairs of stop surfaces on which the ceiling element is held against displacement horizontally normal to the direction of the support profile, is in this case the profile wall 9, which is directly part of the wall-side support profile 2.

[0015] At the end facing away from the wall, the ceiling element 1 has a further extension 11, which projects from above on its side facing away from the wall 4 into the height range of a vertically extending profile wall 12 of the further support profile 3. The mutually facing surfaces of the part of the further extension 11 projecting into said height range and the vertically extending profile wall 12 of the further support profile 3 form a further pair 13 of stop surfaces, which positively block the sliding of the ceiling element 1 in the horizontal direction toward the wall-side profile 2. In this case, the support-profile-side part having a stop surface is a surface of the support profile 3.

[0016] The pairs 10, 13 of stop surfaces ensure that the ceiling element 1 cannot slip due to a purely horizontal relative movement to the point where it falls, even if the ceiling element 1 rests on both support profiles 2, 3 only with a very narrow length range.

[0017] To fold down or remove the ceiling element 1 relative to the support profiles 2, 3, the ceiling element 1 must be lifted on the support profile 3 facing away from the wall just enough to disengage the stop surfaces of the pair 13 of stop surfaces. Then, the ceiling element 1 must be moved horizontally toward the wall 4 until the edge of the ceiling element 1 facing the support profile 3 can be pivoted downwards past the support profile 3. To enable horizontal movement toward the wall 4, there is a space designated as "movement area 15" between the wall-facing end of the ceiling element 1 and the wall 4, into which the wall-facing edge area of the ceiling element 1 can be pushed for disassembly or assembly without colliding with any objects.

[0018] The generalized rule for this states that the displacement area 15 located on one of the support profiles (2) in the horizontal direction, normal to this support profile (2), must be larger than the amount by which a longitudinal section of the ceiling element 1 extends above a region of the second support profile (3) in the same direction.

[0019] Of key importance according to the invention is that the wall-side support profile 2 has a horizontally projecting profile wall 14, which extends into the space below the underside of the flat element 5 of the ceiling element 1. Since the edge area of the flat element 5 facing the wall 4 is not visible when the suspended ceiling is fully installed (from below), the flat element 5 can also be easily shortened at this edge area on site as required by simply cutting it off - with the connecting element 6 temporarily detached - for example with a saw or sheet metal shears. (Adjusting the length of ceiling elements 1 is particularly necessary at the wall-side edges of suspended ceilings, since a predetermined grid dimension for the spacing of support profiles cannot simply be maintained there.) Another advantage is that there is a tolerance between the pairs 10 and 13 of stop surfaces so that the inaccuracies that arise during cutting on site can be absorbed.

[0020] The connection between the flat element 5 and the connecting element 6 of the ceiling element 1 must be designed in such a way that it can be created on site. There are many well-known practical solutions for meeting this requirement within the scope of professional practice, so they will not be discussed in detail here. Tight-threaded plug-in connections are particularly suitable.

[0021] The extension 8 is in the Fig. 1 und Fig. 2 In the example shown, it is designed as a hook curved from above towards the flat element 5. This makes it quite easy to hook the ceiling element 1 onto the wall-side support profile 2 and to pivot it around an axis parallel to the longitudinal direction of the wall-side support profile 2 until it finally hangs only on the support profile 2 and is largely vertically aligned. Fig. 2 This function is especially valuable when there are any installations above the suspended ceiling that need to be accessed occasionally.

[0022] Fig. 3 shows a suspended ceiling according to the invention, in which the necessary connecting element is formed monolithically with the flat element on the ceiling element 1. The connecting element is located on the side of the ceiling element facing the wall-side support profile 16. It is separated from the predominantly longitudinal region of the ceiling element 1 by a slot, which is cut into the ceiling element from below and runs parallel to the direction of the wall-side support profile 16. When the suspended ceiling is installed, a vertically extending profile wall 17 of the wall-side support profile 16 projects from below into the slot on the ceiling element 1. The flank surfaces of the slot then form, together with surfaces of the profile wall 17, the aforementioned pairs of stop surfaces 10, 13.From the base of the profile wall 17, the covering horizontal profile wall 18 of the wall-side support profile 16, required according to the invention, extends in the direction away from the wall 4 below the underside of the flat element of the ceiling element. Since the flat element rests directly on this horizontally aligned profile wall 18, the ceiling element 1 is arranged almost flush with the underside of the wall-side support profile 27.

[0023] For example, if the ceiling element 1 is designed as a C-profile whose profile direction is perpendicular to the direction of the supporting profiles and which is arranged with the base surface facing downwards, the slot cuts through the base surface of the C-profile across its full width and the flank surfaces of the C-profile in their lower height range. Such a slot can also be easily created on site with a simple cut.

[0024] Fig. 4 shows in the same way as Fig. 1 an exemplary suspended ceiling according to the invention, which differs from that of Fig. 1 differs in that on the supporting profile-side edges of the flat element 19, the connecting element 20 and the extension 21 are simply designed as a strip, which is fastened to the underside of the flat element, for example by means of screws. This design is particularly advantageous when the flat element is a self-supporting rigid panel - for example a wooden panel, Plexiglas panel, panel made of a composite material - or is designed as a grid of parallel bars. Furthermore, in this case the connecting elements 20 do not have a hook-shaped structure, so that the ceiling elements cannot simply be suspended from one side of the wall-side supporting profile 2.In this case, both the connecting element 20 and the extension 21 are formed by a strip, which is anchored to the underside of the flat element 19 at one end of the supporting profile side of the latter—for example, by means of screws—and protrudes downwards from the underside of the flat element 19 with its profile surface. Otherwise, the construction works according to . Fig. 4 the same or analogous to those of Fig. 1 and Fig. 3 , so that the description to Fig. 1 also to that of Fig. 4 Except for the exceptions already mentioned, elements that function in the same way have the same position numbers as in Fig. 1 provided.

[0025] Fig. 5 shows an inventive construction of a suspended ceiling, which differs from that of Fig. 1 essentially differs only in that it is optimized for fire protection. For this purpose, the flat element of the ceiling element 1 is provided on its upper side with cover layers of panels 22 made of fire-resistant and heat-insulating material, and the wall-side support profile 23 has an additional profile wall 24 which extends at a distance from the latter over the upper side of the edge region of the ceiling element 1 and is provided with a casing 25 made of fire-resistant and heat-insulating material. In order to be able to move the ceiling element 1 relative to the wall-side support profile 23 according to the invention, a vertical distance must remain between the upper surface of the ceiling element 1 and the casing 25.To ensure that this distance does not become a danger in the event of a fire, the casing 25 is provided on its underside with a strip 26 made of a fire protection swelling agent, which swells in the event of a fire and closes the gap between the casing 25 and the upper side of the ceiling element 1.

[0026] Fig. 6 and Fig. 7 show a construction for a suspended ceiling according to the invention, which is different from that of Fig. 1 is optimized in such a way that the ceiling element 1 is arranged almost flush with the underside of the wall-side support profile 27, and that it can be pivoted and folded down about horizontal axes which are normal to the longitudinal direction of the support profiles, i.e. parallel to the longitudinal direction of the ceiling element 1, if required, and can be folded down and can hang on two support profiles when folded down.

[0027] In this case, the ceiling element 1 comprises a flat element 5, which is typically a metallic C-profile, and a connecting element 28, which is connected to the wall-side end of the flat element, typically by a friction-locked plug connection. The connecting element 28 is typically a bent sheet metal part. One possible construction is shown in Fig. 8 clearly shown.

[0028] The wall-side support profile 27 comprises a horizontally projecting profile wall 29, on which - as in the construction of Fig. 3 - the wall-side edge area of the flat element 5 of the ceiling element 1 rests directly from above. As a result, the wall-side support profile protrudes downwards relative to the ceiling element 1 only by the thickness of the profile wall 29. As a result, the ceiling element 1 and the underside of the wall-side support profile 27 appear to be almost flush with each other.

[0029] The part required according to the invention, which is connected independently of the ceiling element 1 to the wall-side support profile 27 and carries a surface which is part of a pair of stop surfaces which limits the horizontal movement of the ceiling element 27 normal to the support profile 27, is in this case again a wall 30 of the wall-side support profile 27 extending in the vertical direction. The wall 30 is in this case (as in Fig. 3 ) is not arranged at the end region of the profile wall 29 projecting horizontally away from the wall 4, but closer to the wall 4. The connecting element 28 of the ceiling element 1 is like that of Fig. 1 equipped with a downwardly projecting extension 8, which extends from above into the one spatial area between the wall 4 and the vertically extending profile wall 30 of the wall-side support profile 27, so that the required pair of stop surfaces 10 is formed, at which unintentional sliding away of the ceiling element from the wall-side support profile 27 is positively blocked.

[0030] To install ceiling elements 1 according to Fig. 6 and Fig. 7 In order to be able to fold down horizontal axes which are perpendicular to the two support profiles each supporting a ceiling element 1, a folding hook 31 is provided for each connection point between the ceiling element 1 and a support profile. Fig. 6 and Fig. 7 In each case, only the front end of a ceiling element 1 is shown which is located on the side of the wall 4 and thus on the side of the wall-side support profile 27. Regarding the shape and anchoring of the folding hook 31, the arrangement at the opposite front end of the ceiling element 1 can be exactly mirrored.

[0031] The folding hook 31 is typically a relatively stiff bent wire part with several bends, which can all be in the same plane - as in Fig. 7 visible. The hinged hook 31 is pivotally mounted on the wall-side support profile 27, and the ceiling element 1 is pivotally mounted on the hinged hook 31. The two pivot axes 32, 33 are aligned horizontally and parallel to one another, namely parallel to the longitudinal direction of the ceiling element 1, i.e., perpendicular to the longitudinal direction of the wall-side support profile 27. The bearings on the pivot axes 32, 33 ideally have some play, so that even small pivoting movements about axes that can lie in any direction parallel to the plane of the wall 4 are possible. Furthermore, the ceiling element 1 is linearly displaceable relative to the hinged hook 31 in a horizontal direction perpendicular to the wall 4.

[0032] The transfer of the ceiling element 1 from the Fig. 6 shown position into the Fig. 7 The position shown can be achieved in the following steps: a) The ceiling element 1 is lifted vertically until the pairs of stop surfaces 10 at both end faces are disengaged. The folding hooks rotate slightly about the pivot axes 32 on the support profiles. b) The ceiling element 1 is moved horizontally towards the wall-side support profile 27 so that its end face on the wall moves into the designated displacement area 15, and its end face facing away from the wall moves into the free space between the two support profiles, of which the wall-side support profile 27 is one. c) The end face of the ceiling element 1 facing away from the wall is pivoted downwards just far enough that it is completely lower than the lowest surface of the support profile positioned away from the wall (not shown). The folding hook (not shown) positioned away from the wall is rotated downwards by (just under) a quarter turn around its pivot axis on the support profile there.d) The ceiling element 1 is moved translationally away from the wall 4 until its end face facing the wall 4 reaches the free space between the two support profiles, of which the wall-side support profile 27 is one. e) The side of the ceiling element 1 facing the wall 4 is also pivoted downwards. In doing so, the folding hook 31 on the wall-side support profile 27 is turned downwards by about a quarter turn about the pivot axis 32. f) The ceiling element is pivoted downwards about the axes 33 on the folding hook 31 into an approximately vertical position. It can now be released. It can also be moved translationally again slightly towards the wall 4 so that the . Fig. 7 the position outlined is taken.

[0033] The transfer of the ceiling element 1 from the Fig. 7 shown position into the Fig. 6 The position shown can be carried out by following the steps in reverse order.

[0034] The hinged hook 31 cannot be moved translationally away from the wall 4. To avoid collisions with parts of the wall-side support profile 27, it is important that the part 34 of the hinged hook on which the ceiling element 1 is pivotably mounted about the pivot axis 33, as well as the area of the hinged hook that connects the part 34 to the rest of the hinged hook, are further away from the wall 4 than the area of the support profile 27 furthest away from the wall 4.

[0035] For the intended function of the folding hook 31, it is important that the two pivot axes 32, 33 are displaced parallel to each other by a greater amount than the pivot axis 32, about which the folding hook 31 can pivot relative to the support profile 27, is located above the lowest surface of the support profile 27. According to the Fig. 7 In a particularly advantageous embodiment, which is clearly visible, the folding hook 31 has a support area 35 which, when the folding hook 31 is folded down, rests from above on an area of the wall-side support profile 27 which is remote from the wall 4 and from the pivot axis 32 of the folding hook 31. This measure increases the mechanical stability and robustness of the construction when the ceiling element 1 is folded down.

[0036] In the Fig. 6 and Fig. 7 In the exemplary case shown, the folding hook 31 is pivotally mounted on the wall-side support profile 27 in that it rests with a longitudinal region lying horizontally normal to the profile direction of the support profile 27 at the top on the end face of a profile wall 36 of the wall-side support profile 27, and with a longitudinal region aligned parallel to the wall 4, protrudes into a groove delimited by the profile wall 36. In order to prevent the folding hook 31 from being undesirably removed from this position by being lifted upwards, a retaining clip part 37 is used which is anchored in the region of the folding hook 31 in said groove and blocks translational mobility of the folding hook 31 upwards and also parallel to the direction of the wall-side support profile 27.In the advantageous case shown, the retaining clip part 37 is anchored by a combination of a plug-in connection between the groove on the wall-side support profile 27 and an area of the retaining clip part and a snap connection between a stop surface of the wall-side support profile 27 and a resilient part of the retaining clip part 37. The stop surface of the wall-side support profile relevant for the snap connection must be aligned in such a way that it forms a stop surface against movement in the direction that is normal to the profile direction of the support profile and parallel to the direction from which movement out of the groove is possible. Fig. 9 The retaining clip part 37, sketched again as an example, can easily be manufactured as a plastic injection-molded part. With a slightly modified shape, it can also be easily manufactured as a bent sheet metal part.

[0037] The Figuren 6 , 7 , 10 and 11The anchoring of a folding hook, which serves for the foldable anchoring of a ceiling element of a suspended ceiling, to a groove on a supporting profile of the suspended ceiling, using a holding clip part 37, which allows rotation of the folding hook about a predetermined axis, but reliably prevents translational displacement out of the groove, is generally advantageous, even if the suspended ceiling is not designed according to the claims below.

[0038] Within the scope of the invention, many other possibilities for pivotably mounting the folding hook 31 on the wall-side support profile 27 are, of course, conceivable and feasible. The exemplary embodiment shown has two advantages over other embodiments: it is very cost-effective and can be applied to any longitudinal section of the wall-side support profile 27 without any preparatory work.

[0039] The folding hook, not shown here but also required on the support profile required in addition to the wall-side support profile 27, can be designed in the same way as the folding hook 31 shown, and it can also be pivotally attached to the other support profile in the same way.

[0040] The Figuren 10 , 11 und 12 show suspended ceilings in which a versatile, inventively applicable wall-side support profile 38 is used in different applications. In an application in which a ceiling element extends over the entire width of a (narrow) room - which is typically the case for corridor ceilings - on the one hand, the construction of Fig. 10 and on the other hand the construction of Fig. 11 cooperate according to the invention.

[0041] According to Fig. 10 and Fig. 11 the ceiling element 1 and the two wall-side support profiles 38 work together according to the invention by on the left side of the ceiling element 1 they have together pairs 10, 13 of stop surfaces which block horizontal movement of the ceiling element 1 normal to the direction of the support profiles 38, wherein a pair 10 of stop surfaces can be disengaged upwards by a movement of the ceiling element 1 relative to the right support profile 38, and on the right support profile 38 a displacement area 15 extends in the horizontal direction, into which the ceiling element 1 can be displaced horizontally towards this support profile 38 after the pair 10 of stop surfaces on the left support profile 38 has been disengaged, and from each of the two wall-side support profiles 38 a covering horizontal profile wall 39 extends below the lowest surface of the flat element 5 of the ceiling element 1 and covers this downwards.

[0042] In addition, the ceiling element 1 and the two wall-side support profiles 38 are each connected by a folding hook 31, the structure, function and anchoring of which by means of a retaining clip part 37 is the same as in the construction according to Fig. 6 and Fig. 7 are.

[0043] In the construction methods according to Fig. 10 and Fig. 11 The ceiling element 1 is formed from a flat element 5 and two connecting elements 6, which are each connected to one end of the flat element 5 by a plug connection. As shown, the two connecting elements 41 can be designed identically to one another, but depending on the application, they can be inserted into the flat element 5 with one or the opposite side first, so that the area remaining at the front end of the flat element 5 can be used either for the construction according to Fig. 10 fits or for the construction according to Fig. 11 .

[0044] According to Fig. 12 the ceiling element 1 and the wall-side support profile 38 work together by a displacement area 15 extends in the horizontal direction on the support profile 38, into which the ceiling element 1 can be displaced in the horizontal direction towards the support profile 38, and a covering horizontal profile wall 39 of the wall-side support profile 38 extends below the lowest surface of the flat element 5 of the ceiling element 1, and covers this downwards and supports the ceiling element.

[0045] When constructed according to Fig. 12 the flat element of the ceiling element 1 is not provided with a connecting element, and no folding hook is used as an additional connection between the ceiling element 1 and the supporting profile 38. This design is particularly advantageous when the longitudinal direction of the ceiling element 1 is not aligned at a right angle to the profile direction of the supporting profile 38, which occurs in rooms with walls that are not at right angles to one another. To ensure that the ceiling element 1 rests snugly on the lowest profile wall 39 of the supporting profile 38 despite the absence of a stiffening connecting element, the supporting profile 38 is provided with a groove 42 extending above the profile wall 39, into which groove a leaf spring 43 can be inserted, which presses against the lowest surface of the ceiling element 1 from above when the ceiling element 1 is installed.

[0046] The construction according to Fig. 12 According to the invention, the construction of Fig. 10 can be combined by using the construction method according to Fig. 10 is applied and on the other hand the construction according to Fig. 12 However, on the construction side, Fig. 10 The installation of a folding hook can be dispensed with.

[0047] Fig. 13 shows a suspended ceiling according to the invention, in which the wall-side support profile 44 is like that of Fig. 6 a groove open at the top, in which a folding hook can be pivotally anchored if necessary, and a groove 42 open towards the side facing away from the wall, in which, if necessary, as in the construction according to Fig. 12 a leaf spring can be anchored, which can press an edge section of the flat element 5 of the ceiling element 1 against the profile wall 39 of the wall-side support profile 44 located below the edge section.

[0048] In contrast to the previously discussed wall-side support profiles, the wall-side support profile 44 does not have a profile wall to which the ceiling element 1 can be directly suspended in such a way that it is held against excessive horizontal displacement perpendicular to the longitudinal direction of the support profile 44 by stop surfaces 10, 13. The pairs 10, 13 of stop surfaces, which block this displacement, in this case each comprise a surface of a wall 46 of an additional part 47. For this purpose, this additional part 47 is anchored to the wall-side support profile 44 independently of the ceiling element 1, in this case by a snap connection, and the wall 46 of the additional part 47 is aligned vertically, with only the lower edge area being connected to other areas of the additional part 47. Instead of a snap connection, plug-in connections, screw connections, and / or adhesive connections can also be used to attach the additional part.
