Description

[0001] The present invention relates to a ceiling-mountable system and to a method for mounting a ceiling-mountable system.

[0002] Acoustic elements for ceilings are used to improve both the room acoustic and the aesthetic appearance. In addition to their primary function as sound absorbers, elements of this type are increasingly being combined with additional features, such as integrated lighting. These acoustic elements are often attached to the ceiling individually using cable or rod suspensions. Whilst these conventional mounting solutions offer some flexibility, they do have drawbacks, since it is found difficult in particular to arrange a plurality of elements of this type in a visually appealing manner. Previously known systems for attaching acoustic panels, known as “baffles”, utilise holding rails in which the panels are installed along their edges. Whilst these solutions make a uniform arrangement possible, they do have drawbacks, since in general the mounting is labour-intensive and expensive and only offers limited flexibility as regards the positioning or retroactive adaptation of the baffles.

[0007] An object of the present invention is to provide a ceiling-mountable system which makes tool-free mounting and dismounting possible.

[0008] The present invention provides a ceiling-mountable system having the features of claim 1 and a method for mounting a ceiling-mountable system having the features of claim 14.

[0009] Preferred developments form the subject matter of the dependent claims.

[0010] In a first aspect of the invention, a ceiling-mountable system comprises at least one attachment rail, with a first profile portion having a longitudinal extent and a second profile portion extending perpendicular to the first profile portion; at least one functional element, having a longitudinal extent alignable relative to the attachment rail and at least one recess provided in a side face facing the attachment rail; and at least one mounting element,

[0011] the mounting element having a first portion insertable into or attachable to the recess and a second portion which extends perpendicular to the first portion or away from the first portion, is displaceable and / or rotatable relative to the first portion and connected in the first portion, and can be brought into engagement with the attachment rail.

[0012] In a preferred embodiment of the invention, a ceiling-mountable system is provided, comprising at least one attachment rail, with a first profile portion having a longitudinal extent and a second profile portion extending perpendicular to the first profile portion, at least one functional element, having a longitudinal extent alignable relative to the attachment rail and at least one slot-shaped recess provided in a side face facing the attachment rail, and at least one mounting element, the mounting element having a first portion positively insertable into the slot-shaped recess and a second portion which extends perpendicular to the first portion, is displaceable relative to the first portion and connected in the first portion, and can be brought into engagement with the attachment rail.

[0013] In a second aspect of the invention, a method for mounting a ceiling-mountable system according to the invention comprises the steps of:

[0014] arranging a ceiling attachment means on a ceiling surface,

[0015] connecting the attachment rail to the ceiling attachment means,

[0016] connecting the first portion of the mounting element into a recess of the functional element,

[0017] sliding the second portion of the mounting element onto the second profile portion of the attachment rail, and

[0018] locking the second portion of the mounting element to the second profile portion of the attachment rail.

[0019] In a preferred embodiment of the invention, the method for mounting a ceiling-mountable system comprises the steps of: arranging a ceiling attachment means on a ceiling surface; connecting the attachment rail to the ceiling attachment means; inserting the first portion of the mounting element into a slot-shaped recess of the functional element; sliding the second portion of the mounting element onto the second profile portion of the attachment rail; and locking the second portion of the mounting element to the second profile portion of the attachment rail.

[0020] The idea behind the present invention is to provide an attachment system for ceiling-mountable functional elements which makes simple, tool-free mounting and flexible, modular adaptation possible. A specially designed connection between the functional elements and an attachment rail achieves stable but easily adjustable fixing. This makes rapid installation, a visually uniform arrangement, and straightforward dismounting or retroactive adaptation of individual elements possible without the need for additional tools. The mounting elements which allow rotatability achieve substantially free alignability, which can be extended across the entire system. The alignment can be carried out in a simple manner and, by virtue of the mounting elements, without tools. Functional elements can be replaced, removed and even added in a simple manner using a plug-in connection.

[0021] In a preferred embodiment of the invention, the first and the second portion are each provided with at least one magnet, or one of the two portions comprises a magnet and the other portion comprises a ferromagnetic counterpart, the second portion being magnetically attachable to the first portion.

[0022] In a preferred embodiment of the invention, the second profile portion has at least one through-hole at a predetermined position along the longitudinal extent of the second profile portion, it being possible for the ceiling-mountable system to have a plurality of attachment rails, each of which has, at the same position, at a particular position in the direction perpendicular to the longitudinal extent of the second profile portion, a through-hole into which associated mounting elements, which are attached to an identical functional element, can be locked using locking pins.

[0023] The locking pins may be spring-loaded and, upon reaching a position of the through-hole, lock into it with spring assistance. To release the positioning, however, a force must be applied counter to the spring tension so as to release the locking pin from the through-hole.

[0024] In a preferred embodiment of the invention, the functional element comprises a track lighting profile with lighting means, the first portion being designed as a cable suspension which is attached to the functional element.

[0025] In a preferred embodiment, the first portion is formed as a web extending in the longitudinal direction of the slot-shaped recess and retractable into the slot-shaped recess, structures for positive engagement with inner faces of the slot-shaped recess being provided on surfaces of the web positioned against the inner faces. In a preferred development, these structures are formed as tooth-or wedge-shaped projections distributed over the surfaces, in particular arranged in a uniform grid. The tooth-or wedge-shaped projections preferably have a widening counter to a retraction direction.

[0026] The pointed portions thus formed facilitate retraction and penetration into the material of the functional element, while the widening prevents or at least hinders removal of the retracted web from the slot-shaped recess.

[0027] The configuration of the first portion as a longitudinal web, which can be positively retracted into the slot-shaped recess of the functional element, ensures a particularly stable and reliable connection between the mounting element and the functional element. The structures provided on the surfaces of the web positioned against the inner faces of the slot-shaped recess improve the hold by meshing with the material of the functional element. In particular, the design of these structures as tooth-or wedge-shaped projections, distributed over the surfaces in a uniform grid, leads to increased friction and to secure locking of the mounting element in the functional element.

[0028] In one embodiment, the second portion is fixed rotatably in the first portion. This advantageously improves the alignability and adjustment of the functional element. As a result of the rotatability of the second portion, the position of the mounting element relative to the attachment rail can be adapted flexibly, facilitating precise and uniform arrangement of the functional elements. In particular, this construction makes simple fine-tuning possible so as to compensate for manufacturing tolerances or mounting differences without requiring dismounting or retroactive modification of the entire system. This not only simplifies mounting but also makes precise, repeatable positioning of the functional elements possible. A further advantage is that the rotatable mounting of the second portion also makes it possible to adapt to different mounting situations, for example if the attachment rails are not precisely parallel or flush. This increases the flexibility of the system and reduces the effort required for precise pre-mounting of the support elements.

[0029] In one embodiment, the first portion has a longitudinal groove in a side edge facing the second portion, a connecting journal arranged on the second portion being guided in the longitudinal groove. Guiding the connecting journal in the longitudinal groove makes a defined freedom of movement of the second portion relative to the first portion possible, facilitating targeted displacement and adjustment during mounting. This contributes to being able to position the functional elements precisely and to compensating for mounting inaccuracies or structural tolerances. A further advantage of this construction lies in the increased mechanical stability of the connection. The positive guidance of the connecting journal in the longitudinal groove prevents uncontrolled slippage or tilting of the second portion, ensuring precise and repeatable mounting. At the same time, some flexibility is maintained for fine-tuning, without the mounting element having to be released or repositioned. The connecting journal may be configured as a circular or cuboid pin. The pin may have a head at its front end, in other words the end extending away from the second portion. The pin protruding through the longitudinal groove may be secured against falling out or slipping out of the guide groove in the first portion by the pin head. The second portion, which includes the connecting journal, may be arranged rotatably in the first portion. The diameter or width of the pin head may be greater than the width of the guide groove in at least one extension direction perpendicular to the pin. In the configuration having a cuboid pin, the pin head may be formed with widenings extending in two opposite directions perpendicular to the pin. The width of the pin head may correspond to the width of the guide groove. In this embodiment, the pin head may be formed in the manner of a latch, which can lock or latch the second portion with respect to the first portion after a relative rotation of the portions. After the second portion is inserted into the first portion, the portions can be locked by way of the pin head by rotating the second portion relative to the first portion. A rotation of up to 90° may take place in this context, after which the pin head may be aligned perpendicular to the guide groove. By way of the twisting, the first portion can be prevented from falling out or slipping out. In all the aforementioned embodiments, the two portions may be produced simultaneously in an already locked or connected state by a 3D printing process. Alternatively, the portions may be manufactured separately and subsequently connected by inserting the connecting journal.

[0030] In a further embodiment, the first and the second element are each provided with at least one magnet, the second element being magnetically attachable to the first element. The magnetic connection makes rapid, tool-free attachment of the elements possible, significantly reducing mounting time. Simultaneously, the magnetic holding force allows secure fixing of the functional elements without the need for additional mechanical latches or screw connections. This not only simplifies installation but also makes straightforward dismounting or repositioning of the functional elements possible if an adaptation should be necessary. A further advantage of this embodiment lies in the flexible adjustability of the connection. Since the second element can be positioned freely along the first element, the precise alignment of the functional elements can still be fine-tuned even after mounting. This contributes in particular to ensuring visually uniform intervals and to compensating for mounting tolerances.

[0031] In an advantageous development, the second portion has two opposite, elastically deformable clamping elements extending in the direction of the second profile portion, the clamping elements being formed to engage positively around the second profile portion. The elastically deformable clamping elements advantageously make a tool-free, rapid and secure connection between the mounting element and the fastening rail possible. The clamping elements engage positively around the second profile portion and thus generate a stable holding force without the need for additional mechanical attachment means such as screws or closures. This results in a significant reduction in mounting effort and installation time.

[0032] Another advantage of this construction lies in the possibility of repeatable, damage-free dismounting. Since the clamping elements are elastically deformable, the mounting element can be released and repositioned by targeted application of force. This not only facilitates retroactive adjustment of the functional elements but also makes flexible adaptation of the mounting position possible, for example to structural conditions or changes in the room layout.

[0033] In a further embodiment, the clamping elements form a receiving space for the second profile portion, corresponding to the geometry of the second profile portion. The shape of the receiving space, adapted to the geometry of the second profile portion, ensures a precise, positive connection between the mounting element and the attachment rail. This leads to increased mechanical stability of the connection, since the mounting element is fixed to the second profile portion securely and without play. This effectively prevents unwanted movement or release of the functional elements, in particular due to vibrations or external mechanical influences. A further advantage of this configuration lies in the simplified mounting and dismounting. By virtue of the precisely adapted shape of the receiving space, the clamping elements can engage around the profile in an exact fit without the need for additional tools or complex adjustments. At the same time, the elastic deformability of the clamping elements makes tool-free unlocking and easy repositioning of the mounting element along the attachment rail possible if a retroactive adaptation should become necessary.

[0034] In a further embodiment, the second profile portion has bars, extending in the longitudinal direction of the second profile portion and projecting on both sides from the second profile portion, the clamping elements having locking lugs which engage around the bar. The projecting bars on the second profile portion and the corresponding locking lugs on the clamping elements create a positive and non-positive connection which makes reliable fixing of the mounting element to the attachment rail possible. This locking connection ensures a high holding force and prevents unintentional release or slippage of the functional element, even under mechanical stress or vibration. A further advantage of this construction lies in the tool-free mounting and dismounting. As a result of the elastically deformable clamping elements, the locking lugs can be slid over the bars and snapped into their final position. This leads to rapid and easy installation without the need for screws or additional attachment means. Likewise, the mounting element can be released again by targeted application of force, facilitating retroactive adjustment or repositioning of the functional elements. Furthermore, this embodiment contributes to improved long-term stability of the connection. The locking lugs engage securely behind the bars, ensuring high robustness against external forces. At the same time, the defined locking position ensures a precise and uniform arrangement of the functional elements, resulting in visually appealing and reproducible mounting.

[0035] In a further embodiment, the clamping element has a through-hole. As a result of the through-hole, the clamping element can be fixed not only by way of its elastic clamping action, but also mechanically if required, for example using a screw or bolt. This makes a permanent and highly stable attachment possible, in particular in applications where there is an elevated mechanical load on the connection or where additional securing against unintentional release is necessary. A further advantage of this configuration lies in the increased flexibility during mounting. The through-hole can be used to implement various attachment options, making the system suitable both for tool-free and for mechanically secured mountings. This makes application-specific adaptation possible without the need for a fundamentally different attachment element. Additionally, the through-hole can serve as a guide for other components of the system, for example for additional connecting elements, cables or other functional elements. This contributes to the modularity of the system and makes it possible to expand the attachment structure depending on the specific requirements of the relevant application.

[0036] In a further embodiment, the first and second portion can be produced by an additive manufacturing process, in particular by 3D printing. By configuring the two elements in a targeted manner, their connection can be created simultaneously during the 3D printing process, as a non-releasable but movable unit. This eliminates the need for retroactive mounting steps or additional connecting elements, increasing manufacturing efficiency and simplifying the production process. Sequential production of the portions with subsequent mounting is of course also possible. A further advantage of this manufacturing method lies in the precise reproducibility of complex geometries, which would be difficult or laborious to implement using conventional production techniques. In particular, 3D printing makes optimised material distribution and structural adaptation of the connection possible, so as to achieve high stability with simultaneously low weight. Furthermore, additive manufacturing makes rapid and cost-effective production of customised or application-specific attachment means possible without the need for complex tool adaptation or mould production. This leads to increased freedom of design and improved adaptability of the system to different structural conditions. In the magnetic variant, the magnets can be pressed into the respective portions.

[0037] In a development, the functional element has an elongate shape of rectangular or trapezium cross section. The defined geometric configuration as a rectangular or trapezium profile achieves optimal mechanical strength of the functional element, ensuring high inherent stability and reliable fastening. The uniform shape also makes efficient use of the available space and an aesthetically pleasing, orderly arrangement of a plurality of functional elements within an attachment system possible. A further advantage of this construction lies in the central recess along the upper face of the functional element, which makes it possible to receive the mounting elements in a positive fit. This integration achieves secure and precise fixing of the functional elements without the need for additional, complex attachment means. Furthermore, the standardised shape of the functional element makes easy and rapid installation possible, as well as flexible readjustment within the mounting system. In addition, the defined geometry contributes to the functional element being universally usable in various applications, for example as an acoustic element or as a carrier for additional functional elements such as lighting tracks. The rectangular or trapezium cross-sectional configuration makes efficient combination with fastening profiles possible and ensures high modularity of the system.

[0038] In a further embodiment, the functional element is formed as an acoustic panel. As a result of the configuration as an acoustic panel, the functional element can be used in a targeted manner for sound absorption and to improve the room acoustic. This is advantageous in particular in areas with high noise levels, such as open-plan offices, event spaces or public buildings. The combination of mechanical attachment and acoustic functionality makes effective noise reduction possible without the need for separate acoustic measures. Another advantage of this construction lies in the seamless integration into the mounting system. The central recess along the upper face of the acoustic panel allows positive reception of the mounting elements, making stable and tool-free fixing possible. At the same time, the design of the functional elements remains visually appealing and contributes to the harmonious configuration of ceiling or wall surfaces. Furthermore, the formation as an acoustic panel makes versatile use of the system possible. In addition to the sound-absorbing effect, the functional elements can be combined with other functional elements, such as integrated lighting systems. This contributes to multifunctional room setup and increases the efficiency of the room configuration.

[0039] In a development, the functional element has integrated lighting means, in particular integrated into a side face. The direct integration of lighting means into the side faces of the functional elements creates an effective combination of an acoustic solution and a lighting solution. This makes homogeneous, glare-free illumination of the room possible without the need for separate lighting systems. At the same time, the visual uniformity of the ceiling structure is maintained, as no additional light sources need to be visibly mounted. This contributes to a minimalist and clean design aesthetic, in particular in modern architectural concepts. A further advantage of this embodiment lies in the simple installation and power supply. Since the lighting elements are integrated directly into the functional element, the wiring can be routed within the mounting structure and mounted in a concealed manner. This avoids visible cable runs, improving the appearance and also facilitating maintenance. Furthermore, the integration of lighting elements allows targeted light direction so as specifically to illuminate different areas of a room. As an alternative to directly integrating lighting means into the functional elements, separate track lighting profiles may also be integrated into the attachment system. These track lighting profiles are configured to receive additional lighting elements and can be securely integrated into the system using adapted mounting elements. The second portion of the mounting elements locks to the attachment rail with elastic clamping, while the attached first portion consists of a cable suspension, to the lower end of which the track lighting profile is attached.

[0040] An advantage of this alternative solution is the increased flexibility of the lighting configuration. Whilst integrated lighting means provide uniform ambient lighting, track lighting profiles make targeted alignment and adaptation of the light sources possible, for example for accent lighting of particular areas. Furthermore, power may be supplied via an additional cable from the ceiling area or via a ceiling canopy, making straightforward integration into existing building structures possible.

[0041] In an embodiment of the ceiling-mountable system, a ceiling attachment means is provided, which can be fixed in the first profile portion. The targeted integration of the ceiling attachment means into the first profile portion makes it possible to fix the system to the ceiling in a secure, load-bearing manner. This ensures a reliable mechanical connection between the supporting structure and the functional elements attached to it, ensuring high stability and durability of the entire system. A significant advantage of this construction lies in the simplified mounting. The ceiling attachment means can be fixed in the first profile portion in a targeted manner, making rapid and precise installation possible. This not only reduces labour but also minimises the risk of mounting errors. Furthermore, this construction makes flexible adaptation of the fixing points possible, in such a way that the system can be adapted to various ceiling structures in a straightforward manner. In addition, the integration of the ceiling attachment means into the first profile portion contributes to the visual aesthetic of the system, since no additional, visible fixing elements are required. This results in a uniform and harmonious configuration of the mounted system, in particular in modern interior design concepts where concealed attachment is desirable.

[0042] In a development, the ceiling attachment means has a height-adjustable cable suspension. As a result of the height adjustability of the cable suspension, the system can be adapted precisely to the desired room conditions. This makes precise alignment of the functional elements possible, resulting in a uniform and aesthetically pleasing arrangement. Particularly in areas with varying ceiling heights or uneven mounting structures, the height adjustment facilitates positioning in an exact fit. Another advantage of this embodiment is the simple, tool-free adjustment during and after mounting. The cable suspension can be individually adapted, for example to compensate for mounting inaccuracies or to adapt the suspension height retroactively. This eliminates the need to dismount the entire system, leading to significant time savings and simplified handling. Additionally, the height-adjustable cable suspension contributes to improving the sound absorption and light distribution, since the height of the functional elements can be tuned to acoustic requirements or lighting requirements in a targeted manner. This is advantageous in particular in acoustically sensitive areas or in combination with integrated lighting elements.

[0043] In a development of the method for mounting a ceiling-mountable system, a plurality of functional elements are arranged along the attachment rail. The option to mount a plurality of functional elements on one attachment rail makes efficient and compact installation possible. This contributes to a homogeneous and aesthetically pleasing configuration of the ceiling structure, in particular in large-area applications such as offices, conference rooms, or public buildings. The uniform arrangement of the functional elements ensures a harmonious appearance and optimised functionality of the system. Another advantage of this embodiment lies in its expandability by way of linear connectors. These make it possible to connect a plurality of attachment rails and functional elements to form a continuous system, ensuring precise alignment of the elements. As a result, larger areas can be seamlessly equipped with the system without visible interruptions or uneven intervals between the elements. Furthermore, the use of linear connectors facilitates installation because they create a firm and stable connection between the individual modules formed from a plurality of functional elements, which in turn are combined or can be combined to form the system according to the invention. This contributes to the mechanical stability of the system and reduces the need for additional fixing points on the ceiling. At the same time, the system remains flexible, in such a way that individual functional elements can be removed or replaced as needed without dismounting the entire structure.

[0044] Further features and advantages of embodiments of the invention will be apparent from the following description with reference to the accompanying drawings.BRIEF DESCRIPTION OF THE DRAWINGS

[0054] FIG. 5 is a linear connector in an attachment rail of a ceiling-mountable system according to an example embodiment of the present invention.

[0055] In the drawings, like reference signs denote like or functionally equivalent elements.

[0056] FIG. 1 is a perspective view of a ceiling-mountable system 1, comprising a plurality of functional elements 10 and an attachment structure.

[0057] The system 1 comprises a plurality of elongate functional elements 10, each provided with a slot-shaped recess 12 on its upper face 11. In the example embodiment, these functional elements 10 extend substantially orthogonal to a plurality of parallel attachment rails 20. The attachment rails 20 are for receiving mounting elements 30, which are provided for connecting the functional elements 10 to the attachment rails 20. The system 1 is mounted in that the attachment rails 20 are initially attached to a ceiling structure using a ceiling attachment means. Subsequently, the first portions of the mounting elements 30 are inserted into the slot-shaped recesses 12 of the functional elements 10. Afterwards, the second portions of the mounting elements 30 snap into the attachment rails 20, ensuring secure holding of the functional elements 10.

[0058] The illustrated arrangement shows a number of functional elements 10 positioned at regular intervals along the attachment rails 20 so as to ensure a structured and uniform ceiling installation. To form a larger system 1, a plurality of systems 1 as shown here may be combined modularly and arranged on a ceiling.

[0059] FIG. 2 is a perspective view of an attachment rail 20 and a mounting element 30 of a ceiling-mountable system according to an example embodiment of the present invention.

[0060] The attachment rail 20 extends in a longitudinal direction and has on its lower face a second profile portion 22, which extends perpendicular to the first profile portion 21. The second profile portion 22 comprises bars 24, which extend in the longitudinal direction and project on both sides and which can serve for positive engagement with the mounting element 30.

[0061] The mounting element 30 comprises a first portion 32, formed to be retracted into a for example slot-shaped recess 12 of a functional element 10, and a second portion 34, which extends perpendicular to the first portion 32 and is connected to the attachment rail 20. In the example embodiment, the second portion 34 merely has one clamping element 41, which is elastically deformable and provided with a locking lug 38. This locking lug 38 engages positively behind the projecting bar 24 of the second profile portion 22, achieving stable locking and fixing of the mounting element 30 to the attachment rail 20. For further fixing and for positional fixing, for example in a distribution grid, the second profile portion 22 has a plurality of through-holes 25 distributed along its length, which can be brought into engagement with corresponding locking pins (hidden in FIG. 2) on the inner face of the clamping element 41 facing the second profile portion 22.

[0062] The illustrated arrangement shows the structured connection of the individual components of the system 1 and depicts the mechanical fastening of a functional element 10 to the attachment rail 20 by way of the mounting element 30 and the locking of the clamping element 41 to the projecting bar 24 by means of the locking lug 38.

[0063] The ceiling-mountable system 1 may have a plurality of parallel attachment rails 20, each of which has a through-hole 25 at the same position, at a particular position in the direction perpendicular to the longitudinal extent of the second profile portion 22 (and thus at the same longitudinal position, in such a way that the functional element extends perpendicular to each attachment rail 20 in this area).

[0064] As is symbolically shown for a through-hole 25 in FIG. 2, associated mounting elements 30, which are connected to the functional element 10 at the corresponding position, can then lock into said through-hole(s) 25 by way of locking pins.

[0065] FIG. 3a is a perspective view of a mounting element 30 of a ceiling-mountable system according to an example embodiment of the present invention.

[0066] The mounting element 30 comprises a first portion 32, formed as a web which extends in the longitudinal direction of and is retractable into the slot-shaped recess. The first portion 32 has on its surfaces 37, which bear against the inner faces of the slot-shaped recess in the mounted state, structures 33 formed as tooth-or wedge-shaped projections distributed over the surfaces 37, in particular arranged in a uniform grid. The structures 33 are shaped so as to make easy retraction into the recess possible, while simultaneously making pulling out difficult and thus ensuring the positive engagement with the inner faces of the slot-shaped recess.

[0067] Furthermore, the second portion 34 is fixed rotatably in the first portion 32, making flexible alignability of the mounting element 30 possible. The first portion 32 also has, in a side edge facing the second portion 34, a longitudinal groove 35, in which a connecting journal 31 arranged on the second portion 34 is guided. In the example embodiment of FIG. 3a, the connecting journal 31 is formed as a circular pin 65. The pin 65 has a pin head 36 at its front end, in other words the end extending away from the second portion 34. The pin 65 protruding through the longitudinal groove 35 is secured by the pin head 36 against falling out or slipping out of the guide groove 35 in the first portion 32. The second portion 34, which has the connecting journal 31, may be arranged rotatably in the first portion 32. The diameter of the pin head 36 is selected larger than the width of the guide groove 35.

[0068] This structural configuration allows a defined displaceability of the second portion 34 relative to the first portion 32.

[0069] The second portion 34 also has clamping elements 41, which are elastically deformable. These clamping elements 41 are configured so as to make a positive connection to a second profile portion of an attachment rail possible. The clamping elements 41 comprise locking lugs 38, which engage behind bars projecting on both sides from the second profile portion and thus ensure a secure locking connection. The clamping elements 41 form a receiving space 45 for the second profile portion, corresponding to the geometry of the second profile portion.

[0070] The mounting element 30 is configured for production by an additive manufacturing process, in particular a 3D printing process. The first portion 32 and the second portion 34 are designed in such a way that they can be produced in a non-releasable but movable connection during the 3D printing process. Alternatively, the first portion 32 and the second portion 34 may be produced separately, in particular also by an additive manufacturing process, preferably a 3D printing process, and connected after production.

[0071] The image shows the structural configuration of the mounting element 30 and its functional features, in particular the positive structures 33 of the first portion 32, the movable connection between the first portion 32 and the second portion 34, and the guidance of the connecting journal 31 in the longitudinal groove 35.

[0072] FIG. 3b is a perspective view of a mounting element 30 of a ceiling-mountable system 1 according to a further example embodiment of the present invention.

[0073] The mounting element 30 comprises a first portion 32 and a second portion 34, each provided with at least one magnet 39. The second portion 34 can be magnetically attached to the first portion 32, and so a detachable connection can be established between the two portions 32, 34.

[0074] The first portion 32 is formed as an elongate web provided to be received in a slot-shaped recess of a functional element. The surfaces 37 of the first portion 32, which are positioned against the inner faces of the slot-shaped recess, have structures 33 formed as tooth-or wedge-shaped projections arranged in a uniform grid. These structures 33 ensure positive engagement with the inner faces of the slot-shaped recess.

[0075] The second portion 34 is for attaching the mounting element 30 to an attachment rail and has a geometry with clamping elements 41, which makes secure locking to the profile of the attachment rail possible. The magnetic connection between the first portion 32 and the second portion 34 allows flexible adaptation of the position of the mounting element 30 along the longitudinal extent of the first portion 32.

[0076] The image depicts the structural configuration of the mounting element 30 with the magnets 39, which magnetically interconnect the first and the second portion 32, 34.

[0077] FIGS. 3c and 3d are perspective views of a mounting element 30 according to a further example embodiment of the present invention, FIG. 3c being a perspective view and FIG. 3d being a sectional view of the mounting element 30. Elements already described in connection with FIG. 3a are not described again, and reference is made to the statements in connection with FIG. 3a.

[0078] Unlike in the embodiment of FIG. 3a, the pin 65 in the illustrated example embodiment is cuboid in shape. The pin head 36 has two widenings 66a, 66b extending in opposite directions perpendicular to the pin 65. The width of the pin head 36 corresponds to the width of the guide groove 35. In this embodiment, the pin head 36 is formed in the manner of a latch, which locks or latches the second portion 34 with respect to the first portion 32 after a relative rotation of the portions 32, 34, and is then aligned perpendicular to the guide groove 35, the widenings 66a, 66b then being braced against the first portion 32 on both sides of the guide groove 35. After the second portion 34 is inserted into the first portion 32 into the guide groove, the portions 32, 34 can thus be locked, by way of the pin head 36 or the latch formed by it, by rotating the second portion 34 relative to the first portion 32. A rotation, indicated by the arrow D, can thus take place, after which the pin head 36 is aligned perpendicular to the guide groove 35 and the first portion 32 is prevented from falling out or slipping out. In this embodiment too, the two portions 32, 34 may also be produced simultaneously in an already locked or connected state by a 3D printing process. Alternatively, the portions 32, 34 may be manufactured separately and then connected by inserting the connecting journal 31. During connection, the pin head 36 or the widenings 66a, 66b are aligned flush with the guide groove 35, the connecting journal 31 is retracted into the guide groove 35, and the portions 32, 34 are locked or latched by subsequently rotating the first portion 32 relative to the second portion 34. The widenings 66a, 66b are then positioned against the lower face of the first portion 32.

[0079] FIG. 4 is a side view of a ceiling attachment means 40 and an attachment rail 20 of a ceiling-mountable system according to an example embodiment of the present invention.

[0080] The ceiling attachment means 40 comprises a height-adjustable cable suspension 42, provided for attaching the attachment rail 20 to a ceiling structure. The cable suspension 42 consists of an upper cable portion 44, connected to a ceiling anchor 46, and a lower cable portion 48, connected to the attachment rail 20 via a height adjustment mechanism 50.

[0081] The attachment rail 20 extends in a longitudinal direction and is for positively receiving a plurality of mounting elements 30 with functional elements 10 arranged on them. The connection between the cable suspension 42 and the attachment rail 20 is established via the height adjustment mechanism 50, which makes precise adjustment of the mounting height possible. This mechanism allows the position of the attachment rail 20 to be adapted retroactively to ensure precise alignment of the functional elements 10 attached thereto. The mounting element 30 is arranged below the attachment rail 20 and is for receiving a functional element 10. It comprises a first portion 32, which can be inserted into a slot-shaped recess of the functional element 10, and a second portion 34, which is connected to the attachment rail 20. The second portion 34 is provided with elastically deformable clamping elements 41, which wrap around the second profile portion 22 of the attachment rail 20 and bring about locking to projecting bars 24.

[0082] The image depicts the structured connection of the components of the system, in particular the mechanical fixing of the attachment rail 20 via the height-adjustable cable suspension 42 and the functional fastening of the mounting element 30 to the attachment rail 20.

[0083] FIG. 5 shows a linear connector 60 in an attachment rail 20 of a ceiling-mountable system according to an example embodiment of the present invention.

[0084] The attachment rail 20 has a receiving bar 62 for positively receiving the linear connector 60. The linear connector 60 is formed as an elongate connecting element which is guided within the receiving bar 62 and makes it possible to connect a plurality of attachment rails 20.

[0085] A screw 64 is provided for fixing the linear connector 60 within the receiving bar 62. In the illustrated embodiment, the screw 64 is formed as a stud screw and is for clamping the linear connector 60 within the receiving bar 62 so as to establish a secure and stable connection between the connected attachment rails 20.

[0086] The image depicts the positive insertion of the linear connector 60 into the receiving bar 62 of the attachment rail 20 and the fixing by means of the stud screw 64 so as to ensure a stable connection.LIST OF REFERENCE SIGNS1 System
