For simple manufacture and individual room adaptation of ceiling elements 2 and for simplifying assembly and better room lighting, it is proposed according to the invention that the ceiling elements 2 have a closed frame 6, the outward-facing boundary surface of which is covered by a tensioned and at least partially transparent film 7. Preferably, the ceiling elements 2 are square or possibly rectangular, so that the room to be illuminated can be equipped with ceiling elements 2 of the same dimensions.

Description

The invention relates to a suspended ceiling system, comprising a Plurality of ceiling elements, essentially in a horizontal Are arranged level and means for attaching the ceiling elements a floor or on a wall.

A large number of suspended ceiling systems are known in practice, where a plurality of usually square ceiling elements in vertical distance to a floor ceiling. This is often a Scaffold designed in the manner of a supporting grid on supports on the edge or firmly anchored via connections to the floor ceiling and on this scaffold individual ceiling elements stored. The ceiling elements are mostly flat and can easily be lifted out of the scaffolding, which of The advantage is when repairs to lines between Floor ceiling and suspended ceiling should be made. The problem with these known ceiling systems is Illumination of the room below the ceiling system. Due to the Static requirements are usually not possible on the ceiling elements elements to fix luminaires themselves, which is why luminaires often come from the scaffolding have to be detached. From an already suspended ceiling again hanging lights, however, regularly emit an intense and dazzling light that also makes the room uneven illuminated and is therefore often not desired. Instead, it was suggested to replace individual ceiling elements with flat lights, the facing the observer facing the lamp on a housing is attached, in which a light source is arranged at the same time. That on this Wise light is often cold and dirty because the surface is poor can be illuminated and in the rest of dust and dirt hinder the passage of light. Finally, the statics of the grid are required for such solutions clearly oversize so that the ceiling system is expensive overall Manufacture and purchase is and for large-format ceilings Deflection tends.

Suspended ceiling systems are also known in practice  from a plurality of ceiling elements arranged in the manner of a grid ten, which are another element parallel to their surface have, which makes it possible to destroy incident sound waves. This known systems, however, do not integrate lighting, and are above for any type of lighting fixtures arranged on the system very sensitive, as this is the vibrating mass and therefore the sound insulation change behavior.

Suspended ceilings are also known in practice, which one in the Have dimensions of the space surrounding frame on which one Plastic film is stretched, the plastic film is translucent and the Passage of light, starting from a lamp arranged behind the film, allows. The disadvantage of this construction is on the one hand that each ceiling as One-off production to adapt to the dimensions of the room and thus the materials required for this cannot be produced in large series. In addition, this construction requires due to the large clamping forces a pre-bending of the frame, which is only possible with appropriate machines and therefore precludes assembly by the end customer. They are also required films can not be produced in any size, so that in large format seams are visible on the ceiling, on which several foils with each other were connected. After all, the area above the ceiling is just below great effort accessible because the suspended ceiling is not partially solved can be.

It is therefore an object of the invention to eliminate the existing disadvantages and to propose a suspended ceiling system that is easy to manufacture and can be installed and enables large-area lighting.

This is achieved in the ceiling system mentioned at the beginning solved that the ceiling elements have a closed frame, whose outward boundary surface of a tense and for Light is at least partially permeable film is covered. The fiction moderate ceiling system has a plurality of ceiling elements that each have their own closed frame on which one stretched and at least partially transparent film stretched for light is. This ceiling element is preferably square or possibly  Rectangular and forms the smallest unit of a grid ceiling system to be stretched, the base of the frame so is dimensioned so that the film can be stretched onto the frame without a visible seam is. With the ceiling system according to the invention, large rooms can also be used be provided with an almost continuous luminous ceiling, being inexpensive part of the room that goes beyond a standard grid dimension a side panel, or optionally with custom-made products the gap can be closed. The ceiling elements are either on a floor ceiling, for example, hanging over rods, or arranged laterally on a wall, here at least in sections all-round carrier allows storage.

Due to the small format selection of the frame, it is possible to produce it automatically on small machines, the clamping forces which bend the frame inwards are so small that the frame can often not be pre-bent in the opposite direction. The ceiling system according to the invention is also very lightweight, since the film with a thickness of 0.15 to 0.23 mm has a weight of approximately 200 g / m ² and the frame can be made correspondingly lightweight. As a result, the ceiling elements used according to the invention are significantly lighter than previously known luminaire claddings and thus reduce the requirements for the means for fastening to the ceiling or wall accordingly.

Basically, it is possible to illuminate the under the ceiling system formed space by illuminating the ceiling system from below, optionally by lighting in the floor area or in the area below of the ceiling system. However, the provision of is preferred at least one and preferably a plurality of lamps behind the Ceiling elements, with the rays of light coming from the lamps step through the film. A film is expediently used here used, which is translucent and thus a diffuse brightness in the room generated that is free of external effects and especially no sharp Casts shadows of objects that are arranged in the room. The ceiling system is therefore particularly suitable for sales areas or Workplaces in which highly reflective objects are arranged, for example screens, showcases, polished metal surfaces, shiny Paint surfaces, and the like.  

The lamps are expediently in a fixed ratio to the Ceiling elements mounted, for example a lamp for one, four or nine Ceiling elements, with the assignment rule also parts of ceiling elements may include. This standardized assignment makes it possible to quickly and roughly the required for a given ceiling area Determine accessories and determine their arrangement.

A product made of translucent plastic is expediently used as the film, preferably PVC, the thickness of which does not exceed 0.25 mm. The The film used is flexible and can be stretched by approx. 2% to 6% be stretched without tearing, what the clamping on the Frame is useful. In addition and unlike known ones The film can be made of hard plastics or glass used for construction purposes translucent, but not transparent, so that the viewer When the lighting is switched off, the structure of the ceiling system is hidden remains. When the lighting is switched on, the film provided transmits advantageous a wide light spectrum including the ultraviolet and infrared wavelengths in the border area to visible light, whereby to Lighting a variety of colored light sources can be used each of which can be individually influenced in their intensity and where different che colored lamps can be used, so that a color temperature controlled lighting on the back of the ceiling system completely and without Filtering out certain frequency ranges is transmitted and the Viewer the impression of natural light particularly effective mediated. Such light sources emit a frequency and intensity spectrum from that corresponds to that of natural light and therefore as special is pleasantly perceived. Such light sources amplify the scattering effect of the foils further, so that the lighting of the room is very similar to natural light. Through the diffuse exit of the light the film also makes the pleasant spectrum even distributed, with the even illumination of the foils additionally the Gives the impression that it is a natural light. The one with the The aforementioned technical means achieved an aesthetic effect in one A room with such a ceiling system corresponds to that of one Lighting a room with so-called skylights, through which the natural light occurs.  

There is also the possibility of using certain color effects to produce colored light sources.

Is preferably at a distance from and parallel to the first film on the Frame or a second film on a parallel second frame stretched, the space between the two foils dustproof is trained. The two foils are spaced between 2 and 6 cm from each other, with a minimum distance of 4 cm being particularly preferred. This preferred measure ensures that the after Do not deposit dust and insects on the top surface of the bottom film can cause dark spots or to illuminate the ceiling system Lead to inhomogeneities in the observed light. The specified minimum is sufficient to remove the lower (first) film due to the scattering through the fully illuminate the overlying film, which means that even at larger deposits on the upper film, the lower one a homogeneous light sends out. The second film is expediently on the same frame stretched, on which the first film is stretched, so that this a closed interior is already formed. This is also the The distance between the two foils is specified and a compact design realized.

According to a preferred first variant, the frames are more adjacent Ceiling elements in the ceiling system connected laterally, whereby the connection can also be limited to a local connection, so that they can form a surface formed from several ceiling elements, the fastening means for fastening the ceiling elements to the Floor ceiling or arranged on the wall on the frame or by this can be solved again. This makes it possible for small ones Clear a manageable number of ceiling elements, for example four or nine, to form a rather rigid structure and this z. B. on to place supports arranged on the wall. If a suspension on the on the floor above it is provided, on the other hand, it is possible rods, chains or other hanging hanging from the ceiling To connect fasteners with one or preferably two frames, so that the dead weight of the ceiling elements is absorbed vertically and one Deflection of the ceiling system is prevented. A particular advantage of  Arrangement in which neighboring ceiling elements over their frames are interconnected, the small gap that exists between two Ceiling elements are unlit due to their frame.

As a preferred alternative variant, it is possible for a mounting rail Structure is arranged on the fastening means, for example in the Shape of an inverted T on either side of the vertical leg outgoing horizontal leg support surfaces for the frame for Provides. This is particularly suitable for large-format ceilings System for a grid concept, because of the even loading of the two Leg of the mounting rail cheaply the weight of the ceiling elements the fasteners are transmitted and deflection is therefore effective is prevented.

This also advantageously improves the scattering of the light achieves that at least one film has a pimpled structure has at least one side and that the at least one film Has microperforation. Due to the nub-like embossing of the film surface surface or the microperforation becomes an additional scatter or a lot of scatter achieved which leads to an almost complete resolution of the shadow formation leads, which significantly improves the lighting of the room and can be optimized. The effect of the pimpled structure and the The microperforation becomes particularly effective when two foils are spaced apart are used and the film arranged closer to the light source with the knob-like structure or micro-perforation. Through the Microperforation will depend on the sound absorbing properties of the ten ceiling system also particularly affected and improved. The Microperforation can already be seen, for example, in the lower one Foil must be present in order to optimize the sound-absorbing properties to take advantage of. The openings must be large enough to accommodate the Sound waves due to multiple reflection and interference formation in the space between to absorb the films, but must not be too large that insects or Dust particles can penetrate. For further sound absorption and -reduction is proposed that between two films used one fluffy but translucent liner is inserted. Additional advantages and features of the invention emerge from the subclaims and  the description below.

The invention will now be described with reference to the accompanying Drawings based on preferred embodiments of the invention explained in more detail.

It shows:

Fig. 3 shows a cross section through a second embodiment of a suspended ceiling system according to the invention,

Fig. 4 shows a cross section through a third embodiment of a suspended ceiling system according to the invention,

Fig. 5 shows a cross section through a fourth embodiment of a suspended ceiling system according to the invention and

Fig. 6 shows a cross section through a fifth embodiment of a suspended ceiling system according to the invention

The ceiling system, generally designated by the reference numeral 1 , consists of a plurality of ceiling elements, which are generally designated by reference numerals and of which one is shown in cross section in FIG. 1, and a corresponding number of means 3 for fastening the dec kenelemente to a floor ceiling that comprise a cross-sectionally T-shaped support rail 4 and the support rail 4 and all other elements of the ceiling system 1 to an unillustrated floor slab connecting support rod. 5 In the present case, the mounting rails 4 are shown only in the sheet plane. In such an implementation, the ceiling element 2 is essentially rectangular and extends over the entire depth of the room and thus as one piece over the length of the mounting rail 4 . However, it is expedient if the ceiling element 2 is square and transverse to the mounting rails 4, not shown, rail elements are provided which rest on adjacent mounting rails 4 on these and separate adjacent ceiling elements in the manner of an aperture, so that when viewed from below shows the picture of a grid in which ceiling elements 2 are embedded.

Such a square ceiling element 2 is indicated in the perspective view of FIG. 2. The ceiling element 2 has a square frame 6 , which is designed as a hollow square profile with reinforcing ribs, the frame 6 with a flat side of its square profile predominantly stored on a horizontal leg of the T-shaped mounting rail 4 and only inwards with less than a quarter its surface protrudes over this leg. On its upper surface, which faces away from the surface which is deposited on the leg, a film provided with reference number 7 is glued on the edge, the central portion of film 7 remaining within the adhesive connection, which is indicated with reference number 8 , the frame 6 closes completely without showing any tension. Reference number 9 denotes a second frame which is adapted to the dimensions of the frame 6 and is designed as an angular profile and is intended to be pushed onto the first frame 6 in a form-fitting manner, with both the possibility that the angular profile 9 has an interference fit with the frame 6 forms, as well as that a slight game is provided. The angle section 9 reaches with its horizontal leg 9 a on the area of the adhesive 8 of film 7 and frame 6 , while the vertical leg 9 b on the inside of the frame 6 cross-section over the frame and the support rail 4 also protrudes downwards and the film 7 expands and tensions accordingly. The outward end of the leg 9 b is rounded so as not to damage the film. At the same time, the length of the leg 9 b is selected so that the stretching of the film 7 remains in a range of approximately 4% due to the application of the angle profile 9 . The angle profile 9 and the frame 6 are mutually locked in the area of the adhesive 8 by riveting or pinning in order to prevent the film 7 from lifting the angle profile 9 out of its position due to its inherent tension. The resulting ceiling element 2 thus has a tightly stretched film 7 , which is free of folds and non-stretched areas and is ready for installation in order to be placed on a mounting rail 4 . The ceiling system 1 can thus be assembled by a corresponding attachment of the fastening means 3 by means of a prefabricated ceiling element 2 which can be stacked and transported in a simple manner and optionally also assembled by the end user on site. It is to be understood that in a room in which a ceiling element 2 is to be arranged directly adjacent to a vertical wall, instead of the T-shaped support rail element 4 which is suspended from the floor ceiling, an L-shaped angle element is attached to the wall can be whose surface visible from below corresponds to that of a horizontal leg of the T-shaped mounting rail element 4 . A lamp 10 , which is provided essentially centrally to the ceiling element 2 and illuminates it at a corresponding distance, is arranged on the floor ceiling, which is not described in any more detail. The translucent film 7 allows the light from the lamp 10 , which can also be a plurality of lamps, which can be coordinated with one another via a temperature field control in the manner of the light emitted, the area between the mutually facing vertical legs 9 b humidifies the room for the viewer as a homogeneously illuminated surface. It should be noted that the lateral projection fails 9 via the support rails 4 is very low by the chosen structure with a frame 6 and an angle profile and substantially constitutes the negligible usually thickness of the vertical leg 9 b. As far as larger distances are shown in the drawing, this is primarily for illustration, this also applies to the distance of the frame 6 to the vertical leg 9 b of the T-shaped mounting rail 4 , a smaller distance for play compensation will remain regularly. The area between the inwardly directed legs 9 b of two frames, which are arranged on the same mounting rail 4 , remains dark for the viewer, as a result of which the viewer, as an optical impression, has a dark grid with very bright illuminated areas which correspond to the visible area of the film 7 , perceives.

The ceiling system according to FIGS. 1 and 2 is particularly suitable for assembly by the end user who is not familiar with the manufacture of the ceiling elements, since the film 7 can already be delivered glued to the frame 6 and the tensioning and pinning of the angle profile 9 by possibly already predetermined ones Breakthroughs result in a stretched film without the need for additional tensioning tools. Accordingly, the manufacture of the ceiling element 2 is preferably carried out by first producing a circumferential square frame 6 which has an at least triangular cross-section, then on one of the sides of the polygon, which is not the support side of the frame 6 , a film 7 is glued and in a further step, a circumferential angle profile 9 , which is adapted to the geometry of the frame 6 and surrounds it on the inside, is pressed over the frame 6 and the film 7 , as a result of which the film 7 is stretched and finally the frame 6 is connected to the angle 9 , preferably detachably to produce a stretched film 7 as an interface for a ceiling element 2 . This method is easy for a layperson to understand, and the ceiling element 2 produced by the method is immediately ready for use.

Fig. 3 shows a further embodiment of a suspended ceiling system according to the invention, which is basically constructed in the same way as the ceiling system from Figs. 1 and 2 and in which, unless otherwise stated, the same parts with the same reference numerals and comparable parts with an apostrophe are. The suspended ceiling system 1 'from FIG. 3 uses the same means 3 for fastening the ceiling elements as can be seen from FIGS. 1 and 2, which are therefore not dealt with in more detail. The ceiling element 2 'of the ceiling system 1 ' also has a film 7 ', which is provided all round with a piping 8 ', which is a thickening that enables the film 7 'to be gripped and clamped. The film 7 'is mounted on a frame 6 ', a protruding downward the circumferential projection 6 b 'of the frame 6 ' serves as a tensioning strip over which the film 7 'is pulled. A clamping or locking lug 9 'of the frame 6 ' clamps the piping 8 'securely and prevents it from detaching from this anchoring and thus ensures the tension of the film 7 '. The cross-section of the frame 6 'also has a plurality of flanks and undercuts in the manner of a dovetail, which are designated by 6a' and which make it possible to connect adjacent edges of the frame 6 'to a connecting element which engages in two frames 6 ' to couple without this requiring a support rail structure 3 , or to attach the frame 6 'directly to the side of a vertical wall. The suspended ceiling system 1 'also makes it possible to illuminate large areas of a room via the film 7 ', the edge area to the mounting rails 4 being darkened by the selection of the frame 6 , which projects clearly beyond the mounting rails 4 , and a continuously decreasing brightness range causes the transition to the complete facing of the mounting rail 4 . Such steady transitions are often perceived as more aesthetic than strong light / dark contrasts.

Fig. 4 shows a further embodiment of an inventive suspended ceiling system which is characterized in contrast to the previous two apostrophes. The ceiling element 2 "in turn has a square circumferential frame 6 " on which a first film 7 "is stretched over a downwardly projecting section 6 b", the edge region of the film 7 "in the manner of a loop in an outside of the projection 6 b executed recess 6 a "is carried out, and this recess with the film inserted therein is clamped via a clamping strip 8 ". The clamping strip 8 "is preferably formed from an elastomeric material that is anti-slip, whereby a circumferential strip is not necessarily provided must, but it may be sufficient if larger areas of the edge of the film 7 "are held clamped in this way. On an inward flank of the Ausneh mung 6 a" is formed like a nose projection 6 c ", the Strip 8 "pinched and prevented from slipping out of the recess 6 a" by the bias of the film 7 ". In addition, it is possible to lock the terminal block 8 "via bores in the region of the recess 6 a" by inserting pins (not shown), as a result of which a rigid terminal block 8 "is also securely held. It is also possible to apply an adhesive before tensioning, the terminal strip 8 ", film 7 " and frame 6 "effectively connects. Also in the present embodiment, the film 7 "is stretched, with a part of the film 7 ", on which the projection 6 b "rests, on the horizontal leg of the mounting rail 4 , whereby the ausleuchtba re surface of the film 7 " is used to the maximum .

It is alternatively possible to place the area of the strip 8 "on the mounting rail 4 and to shorten its horizontal leg accordingly, which advantageously provides an elastomeric buffer effect of the terminal strip 8 " for a favorable fit between the ceiling element 2 "and mounting rail 4 and at the same time wear the slide 7 "prevented. The frame 6 "also has, on its side facing away from the film 7 " and parallel to the latter, a further film 11 "which can, but does not have to, be the same material as the film 7 ". The film 11 "is stretched and clamped or fastened in a comparable manner to the film 7 ", so that this is not dealt with in more detail. The film 11 "essentially has the task of keeping dirt and falling particles as well as insects and dust away from the area of the film 7 ". In this case, any deposits would only burden the top of the film 11 ″, on the other hand keep the space surrounded by the frame 6 ″ and films 7 ″ or 11 ″ free of impurities that would otherwise be deposited on the top of the film 7 ″ Illumination by means of lamp 10 , which can occur in the case of such deposits, is effectively prevented, the low weight of the film 11 ″ not making the ceiling element 2 ′ according to the invention significantly heavier or bulky. By choosing a suitable distance between the two foils 7 "and 11 " of a little more than 4 cm, it is ensured that impurities on the top of the foil 11 "are no longer recognizable as such by the observer looking at the foil 7 " from below are, since the scattering of the light when passing through the film 11 "is sufficient to ensure a uniform illumination of the film 7 ", on which the measure according to the invention means that there is no longer any contamination. Another advantage of the arrangement of the ceiling element 2 "with two foils according to the invention is that measures to improve the illumination of the lower foil 7 " can already be taken in the area of the upper foil 11 ", for example the provision of light distribution points which scatter light or Furthermore, it is possible to effectively eliminate sound waves, which are always perceived as disturbing in suspended ceiling systems when they are reflected on the ceiling system, for this purpose it is possible to use the film 11 "which is not visible to the viewer , Form with micro perforations or the like, whereby the friction of the sound at these openings ensures the same is extinguished. For this purpose, it can advantageously be provided that the frame 6 "is provided with openings in the form of bores or slots, which are indicated in the present case by the reference symbol 6 d". These openings can be covered on the inside with a fleece (not shown) in order to prevent the entry of contaminants into the interior of the frame. The provision of holes 6 d "also has the advantage that after removing the fleece, the ceiling element 2 " can be rinsed with compressed air, for example, without having to detach the tensioned film, so that, for example, liquid residues deposited due to condensate formation can be dried out.

Fig. 5 shows a further embodiment of the invention, a suspended ceiling system in which the portions different from the previous embodiments, parts are provided with three bars and the rest by the same reference characters for distinction. The ceiling element 2 '''also comprises a lower film 7 ''' and an upper film 11 ''', both of which are stretched over projecting webs of the frame 6 '''. The tension is applied in the same way as in the previous embodiment, and for the same purpose, a terminal strip, not shown, is introduced into a recess 6 a '''of the frame 6 ''', the connection between the terminal strip and recess 6 a ''' is favorably designed by a plurality of grooves in the recess 6 a '''. The ledge 6 b ''', which is designed in the manner of a projecting leg, extends essentially at an angle of 45 ° to the vertical outwards and downwards, and thus represents not only the lower but also the outer extreme of the frame 6 ''' By stretching the film 7 '''over this leg 6 b''', the lower film 7 '''protrudes to the extreme of the peripheral edge of the frame 6 ''', the one facing the film 7 ''' Surface of the leg 6 b '''is designed so that a light incidence on the outer edge of the film 7 ''' visible to the viewer is still guaranteed. Advantageously, this surface has means to bundle the light falling on it in the edge region of the film 7 ''', as a result of which the absolutely smaller amount of light that falls there is concentrated by stronger bundling and deflection, so that the one below the leg 6 b '''lying area of the film 7 ''' is well illuminated. Such a means is, for example, a reflective film which is glued to the said surface of the leg 6 b ''', but it is also possible to vapor-deposit a reflective surface.

Particularly preferred, however, is a geometric configuration in the form of a converging lens bent in one dimension, as indicated at 12, which can additionally have the surface properties in the manner of a reflector or a mirror. It should be noted that when two ceiling elements 2 '''are arranged side by side, the remaining gap of the abutting frames 6 ''' in the plane defined by the film 7 '''becomes minimal, and for the viewer due to the fading effect of the diffuse light is practically imperceptible. Even if a narrower, darker streak is perceived, the fact that the illumination of the rest of the area is very uniform leads to the overall aesthetic impression to be perceived by the viewer being that of a continuously illuminated ceiling and not that of numerous illuminated ones Ceiling elements 2 '''. This circumstance is additionally supported by the fact that one or more lamps 10 are provided for the illumination, which are not necessarily coupled to a ceiling element 2 ''', but rather can also illuminate a plurality of ceiling elements 2 ''' at the same time. As a result, the illumination of adjacent ceiling elements 2 ″ ″ does not differ from the absolute amount, so that the joint is not more clearly recognizable by a gradation in the illumination of the foils. It is possible, similar to FIG. 4, to provide sound insulation measures for the design of the film 11 '''or of the frame 6 ''', that is to say in particular perforations and openings. The means 3 '''for fastening to a floor or a wall engage a central and outward projection 13 of the frame 6 ''', this projection 13 not necessarily being circumferential. The projection 13 has at the end a downwardly bent hook section which is intended to engage in an undercut in a support rail 4 '''. The support rail 4 '''is designed similar to an inverted T-profile, the horizontal legs being essentially designed from the space bent upwards and at a distance from the space required for the hook. As a result, the width of the mounting rail 4 '''is very narrow and can accordingly be provided between the frames 6 ''' which abut one another in the lower region. It should be noted that the outward surface of the leg 6 b '''also springs back, so that it is possible to bring a ceiling element 2 ''' out of engagement with the support rail 4 '''by lifting it laterally with its projection 13 and to pivot past the outwardly directed portion of the leg 6 b "" past the adjacent ceiling element 2 "". This makes it possible to quickly replace individual ceiling elements 2 ″ ″ or to allow access to the parts arranged above the suspended ceiling system 1 ″ ″, for example the lamps 10 , without removing the entire ceiling. Similar to the mounting rail 4 ''', which is suspended from a support rod 5 extending from the floor ceiling, it is possible to provide a mounting rail 4 ''' projecting only on one side on a vertical wall, in which the projection 13 of the frame 6 ''' is hung in the same way. This makes it possible to remove the ceiling element 2 '''from the wall despite illumination of the film 7 ''' reaching almost up to the wall.

The invention has been explained with reference to four preferred Ausführungsbei play in different designs. It goes without saying that the ceiling elements of the various embodiments can also be combined with one another in a common ceiling system. It goes without saying that features of one of the ceiling systems presented can be combined with those of another ceiling system in the context of the present invention, and that a ceiling system or ceiling element formed by such a combination should also be regarded as a further development of the ceiling system according to the invention. It is thus possible to design the frame 6 'shown in FIG. 3 with a leg of the type which is designated by reference number 6 ''' in FIG. 5, whereby a closed ceiling is possible by correspondingly connecting adjacent frames 6 ' in which no mounting rails 4 are visible. It is also possible to design the ceiling elements with only one film 7 in the manner described with a second film 11 for the purposes mentioned. It is also possible to provide the sound insulation means described with reference to the ceiling system 1 'in the other ceiling systems.

FIG. 6 shows a further exemplary embodiment of a suspended ceiling system according to the invention, in which the different parts are provided with the same reference numerals and four lines in order to distinguish them from the aforementioned exemplary embodiments. The ceiling element 2 "" corresponds essentially to the cover element 2 'from FIG. 3 and, like this, consists of a peripheral frame 6 "" and a film 7 "" stretched thereon. The design of the frame 6 , '''and the fastening of the film 7 "" to the frame 6 "" are not discussed here in order to avoid repetition. In contrast to the ceiling element 2 'from FIG. 3, the frame 6 "" in this exemplary embodiment is connected via a joint 15 to the means 3 "" for fastening the ceiling element 2 "" to the ceiling 16 . The joint 15 is a hinge joint, the legs 17 , 18 of which are connected to the frame 6 "" or a connecting profile 19 . The right leg 17 is screwed to the frame 6 "", welded or otherwise connected. The left leg 18 , on the other hand, has a bar 20 , which is arranged perpendicular to the leg 18 and is arranged within a recess 21 of the connecting profile 19 . The leg 18 can also be screwed, welded or otherwise connected to the connecting profile 19 .

On the space side downward side of the connecting profiles 19 , building panels 22 are attached, which may consist of plaster or the like, for example, and serve to veneer the ceiling 16 . On the opposite side facing the ceiling 16 , the Verbindungspro file 19 are connected to a substructure 22 , which may also consist of plasterboard, for example, and which is inserted with its vertically arranged walls 24 into U-shaped grooves 25 of the connecting profiles 19 . On the horizontally arranged wall 26 of the base 23 , three lamps 27 are attached, which illuminate the room via the film 7 "". To maintain these lamps 27 , the ceiling system 1 "" by opening the ceiling element 2 "" can be opened so that the light sources 27 are accessible. Here, the light sources 27 can also be modified so that the lighting conditions in the room can be changed. The connecting profiles 19 are connected via an integrally formed, horizontal web 28 with fastening rods 29 which are anchored in holes 30 in the ceiling 16 . The ceiling system 1 '''can be configured differently with regard to its attachment to the ceiling 16 and the configuration of the frame 6 "" of the ceiling element 2 "" and is not tied to the described embodiment. The main advantage here is that the frame 6 "" is designed to be hinged and thus the light sources 27 are very easily accessible. In order to avoid the emergence of light between the connecting profile 19 and the foldable frame 6 "", a foam rubber seal 32 is received in the connecting profile 19 in a groove 31 , which rests flush after the frame 6 "" has been closed.
