Description

[0001] The invention relates to a suspended ceiling which has a support profile and panels suspended from it.

[0002] Suspended ceilings are often formed by arranging support profiles parallel to one another at a distance from one another in space and by attaching panels to two adjacent support profiles so that they bridge the area between the adjacent support profiles. The support profiles in turn are anchored via a support structure to the raw ceiling above and / or to the side walls of the room. The support profiles very often have a groove which is open towards the bottom, the profile walls which laterally delimit this groove being curved like a hook towards the inside of the groove in the area of ​​the groove opening in profile view. The groove, which is open at the bottom, is often—and from now on also in this application—referred to as “hanging groove”. The matching panels have at least two opposite edges of side walls which are directed upwards and which are curved in a hook-like manner towards the center of the panel surface at their upper end region in profile view. To fasten them, the panels are hung on two adjacent support profiles in such a way that a hook-like curved profile wall of a support profile hooks into a hook-like curved enclosing wall of a panel (in profile view).

[0003] DE 601 03 348 T2 shows a modification of this basic principle. The panels have an enclosing wall that is curved like a hook on only one longitudinal side; on the longitudinal side parallel thereto, the panels have an enclosing wall which is equipped with a latching projection. A panel is hooked onto a support profile as described; the panel is held on the adjacent support profile in that said latching projection rests there as a result of slight elastic prestressing of the panel. If the non-positive connection on the latching projection is released, the panel swings downwards as intended around the catch on the second support profile without detaching itself from the second support profile. The construction is easy to assemble. Disadvantages are that the holding function does not have a high level of security, so that the panel must only be very light - for example, it must not contain any ceiling heating elements or ceiling cooling elements and that there must be a large joint width between adjacent panels to ensure the desired pivotability. Another disadvantage is that the construction is high in the vertical direction, since a wall protrudes upwards from the base surface of the groove in the support profile for the purpose of holding the support profile and because the enclosing walls of the panels also have to be quite high, otherwise the required elastic deformability is not achievable.

[0004] In a widespread modification of the basic principle mentioned at the beginning, the panels have two separate so-called folding hooks. These are hooks which are curved in the same direction as the side enclosing walls of the panel and project slightly upwards from these side walls. The permanent holding function for a panel is accomplished as described by directly hooking two enclosing walls of the panel, which are curved like a hook in profile view, each with a hook-like inwardly curved groove flank on a support profile. For the temporary opening of the suspended ceiling, this hooking of a panel is released and the panel is anchored to two adjacent support profiles with two folding hooks, the panel being pivotable about the connecting line between the two folding hooks. The construction is highly resilient and can therefore also be used for panels with ceiling heating elements or ceiling cooling elements. However, the construction also means that, for reasons of assembly and safety, large gap widths must remain between adjacent panels. Furthermore, the construction is relatively high for two reasons. On the one hand, because the folding hooks always stand vertically upwards from the panel and therefore protrude far above the viewing plane of the panel when the panel is installed and must find space in the groove of the support profile, which is open at the bottom. Secondly, because the support rail is fastened from the top of that profile wall which forms the bottom of the groove which is open at the bottom.

[0005] The main object on which the invention is based is to propose an improved construction for a suspended ceiling, according to which panels with upwardly directed enclosing walls curved in a hook-like manner in profile view are hung on inwardly curved groove flanks of a downwardly open groove of support profiles, the panels also should be able to be held in the folded position by means of folding hooks on support profiles and the panels may also be very heavy. Compared to the construction method of suspended ceilings discussed last, with which all of this can already be realized, the improvement should lie in the fact that – taking economic efficiency into account – smaller joint widths can be realized between adjacent panels and that a lower overall construction height is sufficient.

[0006] To solve the task, the following two measures are proposed, each of which is new and useful on its own, but which are most effective in combination with one another: a) The support profiles are (in profile view) on both sides next to the hanging groove for the panels, which is open at the bottom, each equipped with a further groove, in which fastening elements of the support profiles can be anchored. b) A fold-down hook is pivotably attached to a side wall of a panel and can also be pivoted on the support profile in the suspended state relative to the support profile and can be displaced along the support profile, with the fold-down hook being prevented by a positive fit even when it is pivoted at least approximately to the horizontal to slide out of the anchorage on the support profile.

[0007] The invention is illustrated by means of somewhat stylized drawings.

[0008] figure 1: shows a suspended ceiling according to the invention in a sectional view looking in the direction of the profile of a support profile.

[0009] figure 2: shows three partial sectional views of a sequence of movements during assembly or disassembly of a false ceiling according to the invention with a horizontal viewing direction aligned normal to the support profiles.

[0010] figure 3: shows the carrying profile of in a stylized perspective view figure 1 and figure 2 and a folding hook.

[0011] figure 4: illustrates a special installation situation of a false ceiling according to the invention as a sectional view looking in the profile direction of a support profile.

[0012] figure 5: shows a further special assembly situation of a false ceiling according to the invention as a sectional view looking in the direction of the profile of a support profile.

[0013] figure 6: shows essential parts of another version of a false ceiling according to the invention in a sectional view looking in the direction of the profile of a support profile.

[0014] figure 1 shows a wearing profile 1 , a panel 2 and a folding hook 3 in fully assembled condition.

[0015] The carrying profile 1 has the downwardly open hanging groove on its underside 4 on, the opening area is limited on both sides by a profile wall, which from the underside of the support profile 1 to the inside of the hanging slot 4 is curved like a hook and thus an upwardly open hook 5 forms.

[0016] the panel 2 is typically manufactured as a flat sheet metal cassette. The horizontal main surface is bordered laterally by side walls which stand up vertically from the main surface. The two to the carrying profile 1 parallel side walls 6 are at least partially hook-like at their free upper end to the main surface of the panel 2 curved out so that they have a downwardly open hook portion 7 form.

[0017] A panel hangs in the fully assembled state 2 on support profiles 1 by placing it with one side panel each 6 from below into a hanging groove 4 a support profile running parallel to this side wall 1 protrudes and with the open hook part 7 a hook open at the top 5 in the hanging slot 4of the carrying profile 1 includes. The two opposite, parallel side walls 6 of the panel 2 each engage in one of two adjacent support profiles that are parallel to one another 1 a.

[0018] In addition, the panel 2 with each of the two carrier profiles 1 each with a so-called folding hook 3 connected, which in accordance with the execution figure 1 and figure 2 is manufactured as a bent wire part. The folding hook 3 is on the hook part 7 of the panel pivoted. Using the example according to figure 1 and figure 2 is the folding hook 3 to a ring at its one end 8 bent and thus includes a sheet metal tongue on the hook part 7 . The sheet metal tongue can typically act as a remaining bridge between two punched-out portions of the sheet metal of the hook part 7 be educated.

[0019] On the carrying profile 1 is the respective folding hook 3 also pivoted. To this is its second end, which also becomes a ring 9 is bent in a side chamber 10 the attachment groove 4 stored. The hanging groove is on both side areas 4 each behind the hook 5 with one to the middle of the attachment groove 4 towards open side chamber 10 Mistake. The side chamber is formed in that a low profile wall protrudes from the upper and lower cover surface of the support profile at a small distance from the side wall of the support profile. In the relaxed state is the outer diameter of the ring 9 slightly larger than the clear width at the constriction between the side chambers 10 and the middle part of the attachment groove. Under slight temporary elastic deformation, the ring can 9 through said constriction into the side chamber 10 are pressed and is then loose in the side chamber in the profile longitudinal direction of the support profile 1 displaceable and rotatable about its axis.

[0020] As in combination of figure 1 with figure 2 clearly recognizable, the folding hook points 3 between his as a ring 8 , 9 trained ends two mutually perpendicular areas 11 , 12 on, being attached to the ring 9 subsequent area 12 this one as a transverse part 12 is denoted normal to the plane of the ring 9 aligned, and that to the ring 8 subsequent area 11 this one as a longitudinal part 11 is denoted, parallel to the plane of the ring 9 aligned.

[0021] As in figure 2 outlined, is when the direct interlocking between support profile 1 and panel 2 is solved, the panel 2 nevertheless via folding hooks 3 on the two support profiles 1 held with which it was directly hooked before. There is a folding hook for each 3 each with a side wall 6 of the panel 1 and the support profile belonging to this side wall 1 pivotally connected in the manner described. By the folding hook 3 it can be pivoted in such a way that it does not increase the overall dimensions of the suspended ceiling in the vertical direction when fully assembled. By the folding hook 3 against complete detachment from the support profile 1 and from the panel 2 is positively secured, the panel 2 also held securely against falling if it is not directly hooked to the carrying profile 1 is solved. Due to this safety gain, the direct hooking between the panel 2 and carrying profile 1 be designed flat and short, which means that a low overall height and small joint widths between adjacent panels can be achieved.

[0022] In figure 3 is an alternative to the folding hook 3 from figure 1 and figure 2, which is well made as a bent wire part, a folding hook 13 outlined, which is very easy to manufacture as a stamped and bent part made of sheet metal. The folding hook13 is formed from a sheet metal strip, which is divided into three sections by two 90° bends around axes parallel to one another 14 , 15 , 16 is bent approximately J-shaped. Near the free end of the longer section 14 there is a breakthrough 17 , on which the folding hook 13 rotatable to a side wall, for example by riveting 6 a panel 2 can be connected. It is important that the in the installation situation behind the hook 5 at the attachment groove 4 end section to be arranged 16 of the folding hook 13 is longer and wider than the distance between the hooks 5 and the upper surface of the support profile 1 , so the end section 16 not readily behind the hook 5 out to the opening surface of the hanging groove 4 can be moved towards. With that the folding hook 13 can still be rotated into a position in which the plane spanned by its longitudinal sections is approximately horizontal - which is important for the low overall height - is the width of the transverse part 15 of the folding hook 13 versus the width of the tail section 16 reduced.

[0023] As for the folding hook 3 written also applies to the folding hook 13 : By the folding hook 13 against complete detachment from the support profile 1 and from the panel 2 is positively secured, the panel 2 also held securely against falling if it is not directly hooked to the carrying profile 1 is solved. Due to this increase in security, the interlocking between the panel 2 and carrying profile 1 be designed flat and short, which means that a low overall height and small joint widths between adjacent panels can be achieved.

[0024] By the wearing profile 1 side of that profile surface area, which the hanging groove 4 encloses, with a "retaining groove" 18 designated groove is provided on which fasteners can be mounted, for anchoring the support profile 1 even serve in space, this anchoring can be designed in such a way that it contributes very little, in extreme cases nothing at all, to the overall vertical dimension of the entire suspended ceiling to be formed. Said extreme case is in figure 4 strikingly sketched: An anchor part 19 , for example a hammer head with the contour of a parallelogram, is in the retaining groove 18 deployed. The anchor part 19 is with a bolt 20 rigidly connected, which protrudes from the retaining groove and in the longitudinal area laterally next to the support profile 1 through a kind of pipe clamp 21 is covered from below, which by means of screws 22 on an upper base part 24 is fixed. On the upper base part 24 also lies the carrying profile 1 with its top down on. In extreme cases, the upper fixed base part 24 be the raw ceiling of a room.

[0025] In addition to the saving in height, the lateral retaining grooves 18 also the very valuable advantage that – as in figure 4 recognizable - spacers can be formed between adjacent support profiles by using a longitudinal part (bolt 20 ), which at both ends with an anchor part 19 provided that in the retaining grooves 18 fits, is anchored with one end in the retaining groove of one (left) support profile and is anchored with the other end in the retaining groove of the other (right) support profile. In this way, a precisely defined, robust grid of support profiles aligned parallel to one another at a specific distance can be set up very quickly.

[0026] In practice, the problem often arises that both foldable metallic panels and non-metallic panels such as typically plasterboard surfaces have to be laid as surface elements on a false ceiling. The foldable metal panels are mainly used in areas where easy access to the space above the panels is required. Where said accessibility is not important, the non-metallic panels are preferred for reasons of comfort.

[0027] Hitherto it has not been possible in practice to use a single continuous base construction for supporting both a false ceiling area with hinged metallic panels and a false ceiling area with non-metallic panels. This is now possible due to the construction according to the invention, in which the support profiles for the foldable metallic panels can be designed to be very low. An example of this is in figure 5 outlines: The basic support structure is - as is usual for plasterboard ceilings - by box profiles 23 (also called "Halfen splints") formed. The profile surface of these box profiles is approximately that of a rectangular perimeter open on one side, with the free ends of the legs being curved inwards. In most cases, the open side of the profile is at the top and the box profile is held up by means of parts which protrude into the profile groove and hook onto the inwardly curved free leg ends. in the in figure 5, the upper support structure is formed by parallel box sections with the open side facing up 23 educated. panel elements 25 made of plasterboard are over further box sections 26 on the box profiles 23 fastened by the box sections 26 with their underlying base surface connected to the plasterboard surfaces by screws and by the box profiles 23 with the box profiles 26 by so-called anchor angles 27 are connected. The upper side of the lower box sections 26 lies directly on the lower side of the upper box profiles 23 on. Upper and lower box sections are aligned normal to each other. For fastening hinged metallic panels 2 are also carrier profiles 1 parallel to the lower box sections 26 at the bottom of the upper box sections 23 arranged and fixed. For fastening the support profiles 1 on the box profiles 23 become connecting clamps 28 used, which on the one hand in the lateral retaining grooves of the support profiles 1 are anchored and the other hand to the top of the box sections 23 extend and support there against downward movement. The common height of support profiles 1 and panels attached to it 2 can easily be done by making the side walls of the panels correspondingly high 2 – be adjusted so that this common height is the same as the common height of the panel element 25 and box section 26 , so that the undersides of the panel elements 25 of plasterboard with the undersides of metallic panels 2 cursed.

[0028] in the in figure 5 sketched example is along the support profile 1 running edge of the panel element 25 through a profile 29 bordered, which by the panel element 25 upwards into the hanging slot of the support profile 1 protrudes, there is curved into a hook and like a side wall of a panel 2 is stuck. This supports the carrying profile 1 also holding the panel member 25 . Depending on the width of the individual panel elements 25 made of plasterboard (normal to the longitudinal direction of the support profiles 1 ), it is also possible to use the box profiles 26 to do without and the panel elements 25 made of plasterboard exclusively on support profiles 1 to hang up Especially if you look at the locking arm in the left part of the profile 29 ( figure 5) you can also omit panel elements 25made of plasterboard (or made of another non-metallic material) as well as foldable surface elements as well as metallic panels 2 .

[0029] For reasons of clarity only, figure 4 and figure 5 omitted the representation of folding hooks. In fact, in the use cases outlined, folding hooks – as in figure 1 to figure 3 shown and also described - applied; this also applies to the profile 29 , which is a panel element 25 made of a non-metallic material.

[0030] The exemplary support profile shown in the drawings 1 is easy to manufacture by roll forming sheet metal strip. But it is also quite possible to form support profiles according to the invention by extrusion of aluminum.

[0031] figure 6 shows a further advantageous embodiment of a support profile according to the invention 30 and a matching folding hook to be made from wire 31 .

[0032] The carrying profile 30 has like the carrying profile 1 according to the previous drawings, a hanging groove open towards the bottom 32 where the profile walls which the hanging groove 32 delimit laterally in the area of ​​the groove opening are curved like a hook towards the inside of the groove so that they form a hook on which panels like the panels 2 , 25 can be hooked according to the previous drawings.

[0033] Both sides next to the hanging slot 32 is the carrying profile 30 each with a retaining groove 33 provided, which serves the support profile 30 to wear yourself. Intended for this purpose, hook-like parts protrude from above on the support profile 30 and protrude in a retaining groove with their hook tip pointing upwards 33 , so that the support profile 30 rests with the retaining grooves on the hook-shaped parts hanging down from above.

[0034] In particular, when support profiles are formed by roll forming sheet metal strip, the construction of the support profile 30 cheaper than that of the support profile 1 , in which the retaining grooves are open to the side and not downwards. However, with the carrying profile 30 a construction as in figure 4 outlined, in which support profiles are adjusted to each other by spacers not so easy to realize.

[0035] It is advantageous if - as shown - from the hanging slot 32 facing away from the lateral groove wall of the retaining groove 33 does not protrude as far down as the direct boundary wall of the opening of the hanging slot 32 , because this enables a flatter construction of the ceiling construction.

[0036] In figure 6 are two folding hooks 31 sketched. The right folding hook 31 is shown in the hanging down position. He has this position when the panel connected to him is not directly on the support profile itself 30 is hooked, but only on the folding hook 31 hangs. The left folding hook 31 is shown in the position in which its greatest longitudinal extent is horizontal. He has this position when the panel connected to him directly with the support profile 30 is hooked and the folding hook 31 has no carrying function at all.

[0037] With a hanging folding hook 31 (in figure 6 right) forms the upper part 34 of the folding hook 31 with the longitudinal part hanging vertically downwards 35 of the folding hook 31 a downwardly open hook, which is connected to the opening of the hanging groove 32 laterally limiting groove wall is hooked. One can see that the vertical dimension of the part 34 is at least slightly smaller than the distance between the opening of the suspension groove 32 laterally limiting groove wall to the base of the hanging groove 32 . That is, the folding hook 31 from hooking up with the support profile 30 is detachable when oriented vertically and from the in figure6 is slightly lifted from the position shown on the right and moved to the left.

[0038] The upper part 34 of the folding hook 31 lies with the folding hook installed as intended 31 from the opening of the hanging groove 32 Seen from behind a wall of the support profile that laterally delimits this opening 1 . With the hinged hook aligned to hang 31 is the length of the part 34 in the direction of the profile of the support profile 30 parallel direction significantly greater than the distance of the opening of the hanging slot 32 laterally limiting groove wall to the base of the hanging groove 32 . This achieves that the part 34 of the folding hook 31 not to open the hanging slot 32 can slide toward when oriented horizontally (in figure 6 left) or while it is being swung between vertical and horizontal positions - as happens during assembly and disassembly of panels, since the vertical dimension of the part is thereby reduced 34 is greater than the distance between the base of the hanging slot 32 and the profile wall laterally delimiting the opening of the hanging groove. A high degree of security against unintentional detachment of the folding hook is thus achieved without the intended attachment or detachment being difficult as a result.

[0039] It should be clarified that in this document the statement “the holding groove is located laterally next to the hanging groove” means all constructions in which the center of the cross-sectional area of ​​the holding groove is situated laterally next to the center of the hanging groove. This applies in particular to the construction according to figure 6, in which the centers of the cross-sectional areas of the retaining grooves 33 on both sides next to the center of the cross-sectional area of ​​the attachment slot 32 located although the cross-sectional area of ​​the hanging groove 32 extends further to the side than the cross-sectional areas of the retaining grooves 33 .

[0040] Any of the folding hooks shown in the drawings 3 , 13 , 31 has a part 9 , 16 , 34 on, which then when the fold-down hook on the support profile 1 , 30 is hung, from the opening of the hanging groove 4 , 32 viewed from behind the profile wall laterally delimiting the opening of the hanging groove and ends in the tip of the hook of the folding hook. Furthermore, the folding hooks 3 , 13 , 31 one longitudinal part each 11 , 14 , 35 , which hangs down substantially vertically from the support profile when the panel is opened and approximately horizontally and parallel to the support profile when the panel is fully assembled 1 , 30 is aligned. Third, the folding hooks 3 , 13 , 31 one transverse part each 12 , 15 , 36 on which respectively the longitudinal part 11 , 14 , 35 with the part 9 , 16 , 34 connects.

[0041] During the transfer of the transfer of the panel 2 from the folded state to the fully assembled state are the folding hooks 3 , 13 , 31 the panel with the support profile 1 , 30 connect pivoted so that the longitudinal part 11 , 14 , 35 the hook is transferred from the vertical to the horizontal state.

[0042] The hook level of the folding hook 3 , 13 , 31 is in the case of vertically aligned, intended use on the support profile 1 , 30 mounted folding hook 3 , 13 , 31 normal to the profile direction of the support profile 1 , 30 . When transferring a panel hanging on folding hooks 2 from the folded-down state to the state in which it is ready to be hung on the support profile, the hook plane of the folding hook is pivoted approximately horizontally about a horizontal axis aligned normal to the profile direction of the support profile.

[0043] So that during this pivoting of a folding hook 3 , 13 , 31 this one on the support profile1 , 30 it is important that the transverse part stays positively hooked 12 , 15 , 36 of the folding hook 3 , 13 , 31 , which the longitudinal part 11 , 14 , 35 and the part 9 , 16 , 34 - which ends in the tip of the hook - connects, in the direction normal to the hook plane of the folding hook opposite the part 9 , 16 , 34 jumps back. This springing back means that the catch between the folding hook remains 3 , 13 , 31 and the opening of the hanging groove 4 , 32 laterally limiting profile wall of the support profile 1 , 30 always upright while swiveling the folding hook from the vertical alignment to the horizontal alignment and back.

[0044] The transverse part preferably jumps 12 , 15 , 36 - as shown in the drawings - opposite the part 9 , 16 , 34 back on both sides in the direction normal to the plane of the hook. As a result, it does not matter in which of the two possible directions the folding hook has to be pivoted when it is pivoted from its horizontal orientation to its vertical orientation.

[0045] If with support profiles 1 , 30 , which are on the side of the hanging groove 4 , 32 a retaining groove 18 , 33 If a fold-down hook is used, it makes sense to use this as with the fold-down hook 3 , 13 , 31 described so that he also during pivoting in the horizontal with the support profile 1 , 30 remains stuck. Otherwise you can't really use the most important advantage regarding the lateral holding grooves - low construction of the support profile.

[0046] Conversely, however, it is the case that when a fold-down hook on the hand of the fold-down hook 3 , 13 , 31 described type is used, which remains hooked to the support profile during and after pivoting to the horizontal, a lower support profile than in the prior art can be used even if the support profile has no lateral retaining grooves. The fastening of the support profile upwards can then be formed, for example, by means of screws which run through the upper base surface of the support profile. QUOTES INCLUDED IN DESCRIPTION
