Description

FIELD OF THE INVENTION

[0001] The invention relates to a ceiling element operable for heating or cooling a room equipped with it. Furthermore, the invention relates to a functional ceiling for a room comprising a plurality of such ceiling elements. TECHNICAL BACKGROUND

[0002] It is known to heat and / or cool rooms, especially larger office spaces, using heating and / or cooling devices arranged in a ceiling area. Such heating and / or cooling devices are, for example, designed to be flat overall and may have lines through which a temperature control fluid is conducted. In this way, for example, a floor area can be kept free of heating / cooling devices. Furthermore, such heating and / or cooling can contribute to creating a pleasant indoor climate.

[0003] For example, heating elements are known which are designed with a length of several meters and are suspended from a bare ceiling in the ceiling area of the room.

[0004] DE 200 11 751 U1 further describes a ceiling element with which rooms can be heated or cooled, wherein the ceiling element comprises a mineral fibre board and a gypsum board arranged as a composite.

[0005] Furthermore, a conventional device for air conditioning a room with a heat exchanger located below a ceiling is described in EP 2 410 246 A2. The heat exchanger is formed by a coiled tube that is attached to the ceiling via retaining elements.

[0006] Although the conventional construction methods described above allow for greater flexibility in the floor area, for example, for cabling, it has now become apparent that the conventional arrangement of heating / cooling elements in the ceiling area significantly complicates the planning of the accommodation of other functional components in the ceiling area, such as lighting fixtures. Furthermore, equipping a shell, for example for an open-plan office, in this conventional manner increases the number of trades whose work in the ceiling area must be carefully coordinated.

[0007] Once installed, a ceiling structure designed and constructed using conventional methods, which allows for room temperature control through heating and / or cooling, is very difficult to subsequently modify. The arrangement of components such as lighting fixtures, which perform separate functions in the ceiling area from heating or cooling, is also difficult to modify using conventional methods. Adaptations to changes in room layout or similar requirements are therefore very labor-intensive with conventional construction methods. SUMMARY OF THE INVENTION

[0008] Against this background, it is an object of the invention to create an improved possibility for heating and / or cooling a room and for providing one or more additional functions, which enables simpler planning and installation and can also be subsequently modified with less effort if necessary.

[0009] According to the invention, this object is achieved by a ceiling element having the features of claim 1 and / or by a functional ceiling having the features of claim 12.

[0010] Accordingly, a ceiling element is proposed that can be operated to heat or cool a room equipped with it. The ceiling element according to the invention is designed for installation in a ceiling area of the room and is constructed with a fastening geometry that enables the fastening of one or more further functional elements to the ceiling element. The ceiling element is designed, after its installation in the ceiling area, to mechanically support the further functional element or elements, either alone or in cooperation with at least one further ceiling element. The further ceiling element is, in particular, a ceiling element according to the invention.

[0011] Furthermore, the invention proposes a functional ceiling for a room, wherein the functional ceiling comprises a plurality of such ceiling elements according to the invention, equipped with a fastening geometry, a plurality of support rails, and at least one further functional element, preferably a plurality of further functional elements. The support rails are mounted directly or indirectly to a bare ceiling of the room via additional support elements, or the support rails are integrated into a bare ceiling of the room in an accessible manner. The ceiling elements are arranged side by side and are each mounted and held on at least two of the support rails.According to the invention, it is provided that the further functional element or the further functional elements interact or interact with the fastening geometry of at least one of the ceiling elements and are thereby held on the bare ceiling via the at least one ceiling element and the support rails on which the at least one ceiling element is mounted.

[0012] One idea of the present invention is to propose a ceiling system whose ceiling elements fulfill a heating and / or cooling function can also be used as support elements for further functional elements. The ceiling elements are thus designed in a way that makes it possible to fasten the further functional element(s) to the ceiling element or, for example, to two or more ceiling elements in a defined manner, preferably in a flexible and, if necessary, adaptable manner, and at the same time to absorb the loads introduced into the ceiling element(s) by the functional element, in particular by its weight, and to reliably transmit them into a bare ceiling.

[0013] The invention simplifies the planning and installation of a functional ceiling and reduces the effort and time required. For example, it is no longer necessary to install separate fastening and support devices for each individual system, for example, heating or cooling the room, or for other functions such as lighting, acoustic improvement, sound reinforcement, or information provision. Instead, the invention provides a consistent fastening solution based on the ceiling elements as the carrier of a fastening geometry.

[0014] This makes it possible to plan and implement the expansion of rooms more quickly during new construction or renovation. In this way, office space, for example, can be made available more easily and cost-effectively. Rooms equipped with ceiling elements or a functional ceiling according to the invention also offer significantly greater flexibility for subsequent modifications than conventional construction methods, especially since the additional functional elements do not have to be attached and reattached separately from the ceiling elements designed for heating and / or cooling, but rather use a defined attachment geometry of the ceiling element. This also prevents damage to the equipment used for heating or cooling, for example due to accidentally drilling into pipes carrying temperature control fluid.

[0015] Advantageous embodiments and further developments of the invention emerge from the further subclaims and from the description with reference to the figures.

[0016] In one embodiment, the mounting geometry allows the additional functional element(s) to be mounted on a side of the ceiling element that faces the room after its installation. This allows for the simple and convenient mounting of one or more functional elements intended to fulfill a function in the room.

[0017] In a further development, the fastening geometry is formed on a side of the ceiling element that faces the room after its installation and / or is accessible from this side of the ceiling element. This design advantageously makes it considerably easier for a technician to install or modify functional elements, particularly after full-surface or largely full-surface installation of the ceiling elements, thanks to simplified access to the fastening geometry from the room side.

[0018] In a preferred embodiment, the additional functional element or at least one of the additional functional elements can be a lighting device for illuminating the room or a portion thereof. In the case of lighting devices as functional element(s), the invention achieves significant advantages, especially since numerous lighting devices or elements are often provided in the ceiling area, and their configuration and arrangement must be carefully planned for pleasant and appropriate lighting, as well as often comprehensively adapted when the room layout changes.

[0019] According to a further development, the additional functional element or one of the additional functional elements is an acoustic element for modifying the acoustic properties of the room or a part thereof. The invention also achieves significant advantages in the case of acoustic elements as functional element(s), especially since these elements are often numerous, require considerable installation space, and may therefore require attachment at a variety of locations. The invention thus simplifies the arrangement and spatial coordination of acoustic elements with other, additional functional elements, such as lighting devices, in planning and implementation.

[0020] In yet another embodiment, the additional functional element or one of the additional functional elements can comprise a loudspeaker or a display device, in particular a monitor, or a sensor, in particular a sensor for detecting movement in the room or a sensor for detecting smoke or a gaseous substance or an elevated temperature. The invention thus makes it possible, with minimal effort, to enable sound and / or the display of information, for example, in the room, as well as to provide further additional functions by means of a sensor.

[0021] In particular, the ceiling element is designed as a panel or plate. This allows the ceiling element to act as a flat heating and / or cooling element, enabling effective heating and / or cooling of the room. Ceiling elements of this type can be easily arranged to fill the entire ceiling area, allowing a single area of the ceiling to be used effectively for the temperature control function and other functions.

[0022] In particular, the ceiling element can be elongated.

[0023] According to a further embodiment, a line or lines for receiving a heating or cooling fluid, in particular a liquid, for example water, is / are provided or can be arranged on or in the ceiling element. The heating or cooling fluid can alternatively be, for example, water with additives or, instead, another temperature control fluid. The line or lines can be laid in the ceiling element, for example, in a serpentine or meandering pattern.

[0024] In one embodiment, the ceiling element comprises a base body made of a metal material, in particular aluminum or an aluminum alloy or steel. Such a base body offers, in particular, suitable mechanical strength to serve as a support for additional functional elements.

[0025] In a further development, the base body can be designed, in particular, as a flat profile. This can contribute to the expedient production of a base body, for example, a base body with a geometry that is essentially constant and possibly complex along a longitudinal direction.

[0026] In one embodiment, the fastening geometry is designed with an undercut groove, in particular a T-groove, or several undercut grooves, in particular T-grooves, wherein the plurality of grooves are preferably of the same design. Such grooves enable the reliable fastening of a multitude of additional functional elements in a diverse and flexible arrangement.

[0027] In a further development, the groove(s) can be incorporated into the base body during its manufacture, in particular by extrusion, for example, as a profile. The groove(s) can thus be manufactured in a suitable manner. Manufacturing the base body by extrusion can be particularly suitable if the base body is made of aluminum or an aluminum alloy.

[0028] In a further embodiment, the fastening geometry is designed with a pattern or grid of a plurality of openings, in particular openings of the same type. In a further refinement, the fastening geometry can also be provided with several groups of similar openings arranged in a pattern or grid. Openings of one or more types are well suited if the base body is not manufactured as an extruded profile, for example, but as a sheet metal part or bent sheet metal part, for example, made of steel.

[0029] In particular, the openings, for example, as round holes or elongated holes, can be introduced into the base body by means of punching and / or machining. In this way, the openings can be produced effectively.

[0030] Furthermore, in a further embodiment, the fastening geometry can be designed with one or more undercut grooves, in particular one or more T-grooves, and additionally with a pattern or grid of a plurality of openings that are similar or similar in groups. This creates even more diverse fastening options on the ceiling element.

[0031] In a further development of the functional ceiling, the support rails are mounted on a surface of a concrete ceiling facing the room, either as the slab or suspended from the concrete ceiling, or the support rails are integrated into one or more prefabricated concrete ceiling elements forming the slab, for example, embedded in the prefabricated concrete ceiling element(s). A variety of support rail arrangements are thus possible.

[0032] In particular, the support rails can be arranged spaced apart from one another and parallel to one another. In this embodiment, the longitudinal directions of the support rails preferably extend substantially orthogonally to the longitudinal directions of the ceiling elements. Thus, the ceiling elements can be conveniently supported along their length.

[0033] In one embodiment, the support rails can have a cross-section that is open on one long side, in particular a C-shaped cross-section. This allows for reliable and flexible installation of the ceiling elements on the support rail with a comparatively simple cross-sectional geometry.

[0034] According to a further development of the functional ceiling, adapter pieces are provided, each of which can be inserted into one of the support rails, in particular at a freely selectable location along a longitudinal direction of the support rail, and can be mechanically coupled, preferably detachably, to the support rail. The ceiling elements are designed to be mechanically coupled, preferably detachably, to several of the adapter pieces. For example, the ceiling elements can each be designed to be coupled to one or preferably several of the adapter pieces in opposite longitudinal edge regions of the ceiling element. This enables a highly adaptable installation of the ceiling elements in the ceiling area.

[0035] In one design, the ceiling elements can be clipped or snapped into place with the adapter pieces. This allows for particularly simple and time-saving installation of the ceiling elements.

[0036] In another embodiment, the ceiling elements can be designed to be screwed onto the adapter pieces.

[0037] 4According to a further development of the functional ceiling, the additional functional element or one of the additional functional elements is designed as a lighting device for illuminating the room or a part thereof, or as an acoustic element for modifying the acoustic properties of the room or a part thereof, or as a loudspeaker, a display device, or a sensor. For the advantages of this development, reference is made to the above explanations.

[0038] The above embodiments and further developments of the invention can be combined with one another as desired, where appropriate. Further possible embodiments, further developments, and implementations of the invention also include combinations of features of the invention not explicitly mentioned above or described below with respect to the exemplary embodiments. In particular, those skilled in the art will also add individual aspects as improvements or additions to the respective basic form of the present invention. TABLE OF CONTENTS OF THE DRAWING

[0040] The accompanying drawings are intended to provide a further understanding of embodiments of the invention. They illustrate embodiments and, in conjunction with the description, serve to explain principles and concepts of the invention. Other embodiments and many of the noted advantages will be apparent upon review of the drawings. Elements of the drawings are not necessarily shown to scale relative to one another.

[0041] In the figures, identical, functionally identical and acting elements, features and components are provided with the same reference symbols unless otherwise stated. DESCRIPTION OF EMBODIMENTS

[0042] Fig. 1-29 , 36illustrate a functional ceiling 1 according to a first embodiment of the invention. The functional ceiling 1 is intended for installation in a room 100, for example, in an office space, such as an open-plan office. However, the functional ceiling 1 can equally be useful for and used in a variety of other types of rooms.

[0043] The functional ceiling 1 comprises a plurality of panel- or plate-like, elongated, similar ceiling elements 3, each of which can be operated for heating or cooling the room 100 equipped with the ceiling element 3 and which are designed to be mounted in a ceiling area 101 of the room 100.

[0044] The ceiling element 3 has a base body 23, which is formed as a flat profile made of aluminum or an aluminum alloy. During the production of the base body 23, which can be carried out in particular by extrusion, the base body 23 was provided with several similar, undercut grooves 143. The grooves 143 extend parallel to one another and parallel to a longitudinal direction L3 of the ceiling element 3 on a side 13 of the ceiling element 3, which faces the room 100 after its assembly, and open toward the side 13.

[0045] On a side of the ceiling element 3 opposite side 13, which faces the room 100 after the installation of a bare ceiling 102, the ceiling element 3 is equipped with at least one fluid-carrying line 33 in which a heating and / or cooling fluid, in particular a liquid such as water, can circulate. The line 33 can be arranged on the base body 23 between ribs 63 provided integrally thereon and held by these ribs 63. Fig. 22 for example, shows in a cross-sectional view such ribs 63, which are also produced, for example, during the extrusion of the base body 23 and together form a channel with a rounded base, whereby good contact and good heat transfer between line 33 and base body 23 is achieved.

[0046] The ceiling elements 3 can, for example, each have a length of approximately 6 m, although other lengths are also conceivable.

[0047] The functional ceiling 1 further comprises several support rails 2, a plurality of adapter pieces 5 and further functional elements 4.

[0048] Fig. 4-7 illustrate some steps of the installation of the functional ceiling 1 in the ceiling area 101 of the room 100.

[0049] First, the support rails 2 are fastened to the soffit 102 parallel to one another at intervals, in particular at equal intervals, for example at a distance of 2 m from one another. For this purpose, the support rails 2 can be Fig. 30 illustrated by way of example, can be fixed directly to a surface of the bare ceiling 102 facing the room 100, for example by screwing, or instead indirectly with the aid of additional holding elements 22, as in Fig. 32 shown, suspended from the soffit 102 to create a distance between the support rails 2 and the soffit 102. The soffit 102 is in Fig. 30, 32 each formed as a concrete ceiling 103, although a different ceiling construction may also be considered instead. Alternatively, the support rails 2 may be embedded in a prefabricated ceiling element, such as a prefabricated concrete ceiling element 103', and thus integrated. Such an embedding of the support rail 2 is shown, for example, in Fig. 31 .

[0050] The support rails 2 are designed identically to one another and each have a C-shaped cross-section which is open on one longitudinal side 12. The open longitudinal side 12 faces the room 100 after the mounting or embedding of the support rail 2. In the case of embedding the support rail 2, as in Fig. 31 , at least the open long side 12 is accessible from the room 100.

[0051] The adapter pieces 5 serve to mount the ceiling elements 3 on the support rails 2, wherein the ceiling elements 3 in the embodiment shown are arranged next to one another and parallel to one another in such a way that the longitudinal directions L3 of the ceiling elements 3 run essentially at a right angle to the longitudinal directions L2 of the support rails 2.

[0052] Several adapter pieces 5 are arranged at a distance from each other on the support rails 2, see Fig. 5 . The Fig. 14-16 The adapter pieces 5 shown enlarged are of similar design and each have a base part 75 on which locking elements 15 designed as spring elements, which can also be referred to as locking springs, are arranged on both sides. In addition, each of the adapter pieces 5 has an engagement element 25 that is rotatable relative to the base part 75. In order to couple the adapter piece 5 to the support rail 2, the adapter piece 5 is inserted at a freely selectable location along the longitudinal direction L2 with the engagement element 25 leading through the open longitudinal side 12 of the support rail 2 into the interior of the latter.

[0053] The engagement element 25 is flat, elongated and plate-like and has two diagonally opposite, rounded corners and two further, opposite corners substantially without rounding. Fig. 14-16 show that during insertion, a longitudinal extension direction of the engagement element 25 runs essentially parallel to the longitudinal direction L2 of the support rail 2. When the engagement element 25 is located completely inside the support rail 2, the engagement element 25 is rotated from the space 100 by an angle of approximately 90 degrees. For this purpose, an engagement geometry of a pivot 35, which is firmly connected to the engagement element 25 and mounted in the base part 75, can be accessible on the side of the adapter piece 5 facing away from the support rail 2, for example through an opening in the base part 75. After rotating the engagement element 25, the adapter piece 5 is mechanically coupled to the support rail 2 quickly, easily, and reliably. This mechanical coupling can be released if necessary by rotating the engagement element 25 in an opposite direction.

[0054] The adapter pieces 5 are, see Fig. 5 , in this way, attached to the support rails 2 such that corresponding adapter pieces 5 on each of the support rails 2 are aligned with each other. The free selection of the position of the adapter pieces 5 along the support rails 2 enables a high degree of flexibility in positioning the ceiling elements 3 in the direction L2.

[0055] In variants of the first embodiment, the adapter pieces 5 could be fastened to the support rails 2 in a different way, for example by clipping, locking or by means of screws.

[0056] After fixing all adapter pieces 5, the ceiling elements 3 are each snapped into place on several of the adapter pieces 5 from the side of the room 100 and are thereby mechanically held releasably on the support rails 2. Here, each ceiling element 3 is attached to at least two support rails 2, in Fig. 6 For example, mounted and held in place on three mounting rails 2.

[0057] In this way, the ceiling elements 3, as well as additional, narrower ceiling elements 3a, for example for peripheral areas of the room, are arranged next to one another, filling a flat area of the ceiling area 101. Fig. 17 shows an enlarged view of a section of a ceiling element 3a, which is Fig. 17 For example, it is not provided with a line 33 for heating and / or cooling, but serves, for example, as an edge finish. In a variant, a line 33 could also be arranged on the ceiling element 3a.

[0058] The mechanical coupling of the ceiling elements 3 with the adapter pieces 5 and thus with the support rails 2 is in the Fig. 20-22 Enlarged view. The ceiling elements 3 each have an edge region 53 on both longitudinal sides, which is formed as an L-shaped rib in the profile cross-section of the base body 23. One leg of the L-shape protrudes outward at the longitudinal edge of the ceiling element 3. The ceiling elements 3a can be provided with longitudinal edge regions 53 in a similar manner.

[0059] On a side opposite the engagement element 25, the base part 75 of the adapter piece 5 has a central section 55 and wall sections 45 arranged symmetrically on both sides thereof. Each of the wall sections 45, together with the central section 55, defines a channel-like interior region into which the resilient locking elements 15 project at an angle from the central section 55.

[0060] For the mechanical coupling of a ceiling element 3, or 3a, with the adapter pieces 5, the edge area 53 is introduced into the interior area between the central section 55 and the wall section 45, wherein the free-standing leg of the L-shape slides over the ramp-like inclined locking element 15 and resiliently pushes the locking element 15 back until it snaps behind the free leg 153 of the L-shape of the edge area 53, see in particular Fig. 22 To release the locking coupling, a sufficiently flat tool can be used, for example, to push back the locking element 15. In this way, the ceiling elements 3, 3a can each be clipped or locked to the adapter pieces 5 at their edges, leaving only a narrow gap between adjacent longitudinal edges of adjacently arranged ceiling elements 3, 3 or 3, 3a. The interaction of the edge regions 53 with the locking elements 15 can also advantageously enable freely selectable positioning of the ceiling elements 3, 3a in the direction L3.

[0061] After fixing the ceiling elements 3 and if necessary 3a, a substantially closed surface is formed, see Fig. 6 , which enables heating or cooling of the room from the ceiling area 101. The ceiling elements 3 are reliably and at the same time easily mounted by the support rails 2 on the bare ceiling 102.

[0062] At the same time, in the functional ceiling 1, as described below, the ceiling elements 3 serve as supports for the additional functional elements 4. The additional ceiling elements 3a can also serve as such supports in some designs. Not all adapter pieces 5, by means of which the additional ceiling elements 3a can be held, are shown in the figures.

[0063] For this purpose, the undercut grooves 143 are designed as flat T-slots. The T-slots 143 form a fastening geometry 43, which is accessible from the side 13 of the ceiling elements 3, 3a facing the room 100 after installation and is arranged on the side 13. The fastening geometry 43 enables the fastening of a plurality of the additional functional elements 4 on the side 13 of the ceiling elements 3, 3a facing the room 100, with each additional functional element 4 interacting with the fastening geometry 43.

[0064] Fig. 6 shows the essentially closed, continuous surface formed by the ceiling elements 3 and 3a, which is equipped on the underside with the parallel grooves 143 facing the room 100.

[0065] For example, an additional functional element 4 can be mechanically supported by only one of the ceiling elements 3 or by a ceiling element 3 in cooperation with one or more additional ceiling elements 3 or 3a. The ceiling elements 3, 3a, the adapter pieces 5, and the support rails 2 are designed to reliably transfer the loads, in particular weight forces, that the additional functional elements 4 impose on the ceiling elements 3 and, if applicable, 3a, into the bare ceiling 102.

[0066] Two exemplary further functional elements 4 as components of the functional ceiling 1 are shown Fig. 7 One of the further functional elements 4 is designed as a lighting device 14 for illuminating the room 100 or a part of the room 100, for example as an elongated lighting device 14. A further functional element 4 is designed as an acoustic element 24 and serves to modify, in particular improve, the acoustic properties of the room 100 or a part thereof.

[0067] A completed functional ceiling 1 shows Fig. 8 in perspective view from a visible side of the functional ceiling 1, which faces the room 100 and is arranged in the ceiling area 101. The ceiling elements 3 carry a plurality of similar, elongated and parallel acoustic elements 24 as further functional elements 4, of which Fig. 8 For the sake of clarity, only some are marked with the reference number 24.

[0068] Between two of the acoustic elements 24, an elongated lighting device 14 is arranged as a further functional element 4, essentially parallel to these.

[0069] Fig. 8 further shows that in Fig. 8 the longitudinal directions L3 of the ceiling elements 3 run parallel to a longitudinal direction L14 of the lighting device 14 and parallel to a longitudinal direction L24 of the acoustic elements 24. The longitudinal directions L3, L14 and L24 are also aligned essentially perpendicular to the longitudinal directions L2 of the support rails 2. In the exemplary embodiment in Fig. 8 each of the further functional elements 4 is mechanically supported by one of the ceiling elements 3 at several points along the same.

[0070] The multitude of similar T-slots 143, which serve as the fastening geometry 43, enables a very diverse, flexible arrangement of the other functional elements 4. Their fastening using the T-slots 143 is described in more detail below. In this regard, particular reference is made to the Fig.17-27 and 36 referred to.

[0071] On the acoustic element 24, which is designed, for example, with a narrow, elongated basic shape, a plurality of fastening components 6 are arranged on a narrow longitudinal side, for example four fastening components 6, which are distributed over the length of the acoustic element 24 and arranged at intervals from one another. Fig. 17-19 , 24 show one of these each. Fig. 36 shows the fastening component 6 fixed in a flat recess of the acoustic element 24.

[0072] The fastening component 6 has two fixed hook sections 36 on a first side thereof and two movable hook sections 16 on a second side opposite the first side. The fixed and movable hook sections 36 and 16 are designed to engage behind the undercuts of the flat T-slot 143 and in this way to fasten the acoustic element 24 using the fastening geometry 43, see for example Fig. 22, 23 For fastening, the fixed hook sections 36 can be inserted behind the undercut on one side of the T-slot 143, and then the acoustic element 24 can be pivoted into its end position, whereby the movable hook sections 16, in particular with the aid of sliding ramps pointing away from the acoustic element 24, engage behind the undercut on the other side of the T-slot 143. An actuating section 26 of the fastening component 6 enables retraction of the movable, for example spring-loaded, hook sections 16 in order to release the acoustic element 24 again. Fig. 19 , 22 , 24, 25 show that the operating section 26 is accessible after fastening the acoustic element 24 on the side 13 of the ceiling element 3. Acoustic elements 24 fastened in this way show Fig. 19-25 .

[0073] The further functional element 4 designed as a lighting device 14 is, for example, in Fig. 19 suspended from a ceiling element 3 using the fastening geometry 43 by means of two similar fastening components 7. If necessary, more than two fastening components 7 can be used, which, depending on the orientation of the lighting device 14, can interact in the same way with the fastening geometry 43 on two or more of the ceiling elements 3.

[0074] The fastening component 7 is in Fig. 21 , 26 und 27 illustrated in more detail and can be designed, for example, as a substantially one-piece component to which a cable 37 for suspending the functional element 4 is connected. On a side opposite an exit of the cable 37, the fastening component 7 has an engagement element 27, which is formed, for example, in one piece with an actuating area (not further designated) accessible from the side 13 of the ceiling element 3. The engagement element 27 is formed in two sections, between which a recess 17 is provided. A fitter can insert the engagement element 27 into the T-slot 143 and then, using the actuating area, rotate it through an angle of approximately 90 degrees, whereby the engagement element 27 engages behind the undercuts of the T-slot 143. In Fig. 27 The rotation is indicated by a double-dash-dotted arrow. The recess 17 can allow a certain elastic retraction of the sections of the engagement element 27 in the lateral direction of the T-slot 143 during rotation, whereby the fastening component 7 is in the fixed position, see Fig. 26-27 , sits firmly.

[0075] The fastening components 6 and 7 can each be fixed with high flexibility at a freely selectable location of a selected T-slot 143, so that the functional element 4 can be freely placed along the T-slot 143.

[0076] In a variant of the first embodiment, in a functional ceiling 1, which is shown in Fig. 28 is illustrated, functional elements 4 are fastened to the ceiling elements 3 and / or 3a in such a way that a longitudinal direction of the further functional element 4 does not extend parallel, but at an angle to the longitudinal directions L3 of the ceiling elements 3, in particular at right angles to the longitudinal directions L3. Fig. 28 This is shown by way of example for a lighting device 14 whose longitudinal direction L14 runs perpendicular to the longitudinal direction L3 and parallel to the longitudinal direction L2 of the support rails 2. The lighting device 14 is suspended from two of the ceiling elements 3. Acoustic elements 24 can also be arranged with the longitudinal direction L24 aligned at right angles, or at a different angle, to the longitudinal directions L3. Furthermore, in a variant not shown in the drawing, it is possible to arrange the further functional element 4, such as the lighting device 14 or the acoustic element 24, not parallel to a plane formed by the ceiling elements 3, but obliquely to it, for example by means of cables 37 of different lengths.

[0077] Fig. 29 illustrates some parts of a functional ceiling 1 according to yet another variant of the first embodiment, wherein a lighting device 14 is arranged in the same way as in Fig. 28 is arranged and fixed. In the Fig. 29 In the functional ceiling 1 shown, in addition to the lighting device 14, further functional elements 4 are provided. One of the further functional elements 4 is designed as a display device 34, in particular a monitor. On the monitor, for example, information for the users of the room 100 can be displayed. The display device 34 is attached to two adjacent ceiling elements 3, for example suspended. Another of the further functional elements 4 is in the variant of the Fig. 29 designed as a loudspeaker 44 and suspended from one of the ceiling elements 3. The fastening of the loudspeaker 44 and the display device 34 is shown in Fig. 29 implemented in the same way as described for the lighting device 14 by means of fastening components 7.

[0078] In addition, this can Fig. 29 The further functional element 4, schematically illustrated and designed as a loudspeaker 44, can instead be designed, for example, in the same or similar form as a sensor or with a sensor. The sensor can, for example, be a motion sensor that detects movement in the room 100, for example, in order to provide control of the lighting device 14 based thereon. Furthermore, it is conceivable to attach sensors of other types, such as smoke detectors or sensors for detecting heat or a gaseous substance, in a manner analogous to the loudspeaker 44.

[0079] Further functional elements 4, embodied as lighting devices 14 or acoustic elements 24 or display devices 34 or sensors or loudspeakers 44, can be provided in functional ceilings 1, 1' according to all embodiments of the invention described here. Various combinations of the aforementioned functional elements 4 are possible. However, other functional elements 4 of a different type are also conceivable.

[0080] The functional ceiling 1 advantageously offers the possibility of utilizing a ceiling area intended for heating and / or cooling the room in a space-saving, cost-saving, and aesthetically pleasing manner for accommodating additional functional elements 4, such as lighting, acoustic enhancement, sound reinforcement, information display, or sensor technology. The functional ceiling 1 can be planned and implemented in a time-saving manner and offers the possibility of rearranging or replacing the functional elements 4 as needed with reduced effort, for example, if the use of the room 100 changes.

[0081] A functional blanket 1' according to a second embodiment is shown in Fig. 33 und 34 shown schematically and in detail. The functional ceiling 1' has support rails 2, adapter pieces 5, ceiling elements 3', and further functional elements 4. The support rails 2 and adapter pieces 5 are designed and mounted as above for the first exemplary embodiment. Furthermore, the functional elements 4 are designed as explained above for the first exemplary embodiment, but each is equipped with fastening components 6' that are modified compared to the first exemplary embodiment.

[0082] In the second embodiment, the ceiling elements 3' are also equipped with lines 33 for a heating and / or cooling fluid.

[0083] However, unlike those of the first embodiment, the ceiling elements 3' of the second embodiment do not have visible T-slots as a fastening geometry for the additional functional elements 4. In the second embodiment, the ceiling element 3' is flat and smooth on the side 13 facing the room 100 after assembly and has a fastening geometry 43' for the additional functional elements 4, which is formed with a pattern or grid of a plurality of openings 143' and 243'.

[0084] In the second embodiment, see Fig. 34 , the fastening geometry 43' is formed with a plurality of similar round holes 143' and a plurality of similar elongated holes 243'. In variants, differently shaped openings can be provided instead. Furthermore, in variants of the second embodiment, it is possible to incorporate only one type of similar opening as the fastening geometry 43'.

[0085] In the second embodiment, each functional element 4 has one or more of the fastening components 6'. The fastening component 6' is designed to engage in one or more of the openings 143' and 243' and to engage behind the base body 23' in order to hold the functional element 4 to the ceiling element 3'. For example, the fastening component 6' can have a rotatable engagement portion or a latchable engagement portion.

[0086] The ceiling element 3' of the second embodiment is formed, for example, from a steel sheet. For example, a base body 23' can be manufactured from the steel sheet by bending it as a whole or by bending individual parts and connecting them. The openings 143', 243' can be created, for example, by punching in a time-saving manner. Alternatively, the openings 143', 243' could be created by other means, such as machining.

[0087] In yet another variant, openings, for example analogous to the openings 143' and / or 243', could be combined with grooves, such as the T-grooves 143 of the first embodiment, in a fastening geometry of a ceiling element in order to enable an even greater number of different fastening methods.

[0088] In yet another embodiment of a functional ceiling, which is Fig. 35 is only shown in detail, ceiling elements 3" can be screwed to an adapter piece 5" by means of screws 65" instead of being locked. In addition, the adapter piece 5" and the ceiling element 3" can be designed as described above for the first or second embodiment for the adapter piece 5 and the ceiling elements 3, 3a, 3'.

[0089] Although the invention has been fully described above using preferred embodiments, it is not limited thereto but can be modified in many ways. LIST OF REFERENCE SYMBOLS
