Description

[0001] The invention relates to a mounting device for mounting a support element of an accessory device on a mounting surface of a building.

[0002] Furthermore, the invention relates to an assembly system with such an assembly device.

[0003] Furthermore, the invention relates to an assembly arrangement with such an assembly system. STATE OF THE ART

[0004] Equipping buildings with various types of accessories is ubiquitous today. A wide variety of accessories exist, with solar modules or solar collectors for generating renewable electrical or thermal energy being among the most popular. Solar modules can be mounted on various surfaces of the building. The most common mounting surface is the roof or corresponding roofing elements, especially pitched roofs, to which the solar modules or solar collectors are attached.

[0005] A large number of different mounting devices or mounting systems for mounting solar modules are known from the state of the art.

[0006] For example, DE 10 2008 0150 894 B1 discloses a mounting device in the form of a multi-angled hook element, which can be subsequently mounted to supporting components of a roof substructure after the roof has been covered. To install this mounting device, it is necessary to remove individual roofing elements, in particular roof tiles, from the previously fully covered roof in order to attach the mounting device to the underlying supporting components. The roofing elements are then reinstalled in such a way that recesses are created through which the mounting device can protrude to attach the solar modules. Alternatively, the recesses are incorporated directly into the roofing elements, thus mechanically modifying them.

[0007] This known mounting device has the disadvantage that it requires considerable effort to install, as large sections of the roof must be uncovered again and / or extensive modification of the roofing elements is necessary to create the cutouts. Furthermore, the cutouts pose a risk of negatively impacting the roof's watertightness and stability.

[0008] Another type of known mounting device is a roof covering element, usually a roof tile, which has a base element on its upper surface for the indirect mounting of solar modules. Such a mounting device also includes a coupling element, which serves as a connection between the base element and the solar module or a mounting rail of the solar module and can therefore be positioned on the base element. The coupling element is positioned on the base element in such a way that, due to the mechanically determined positioning options for the coupling element, a fixed, unchangeable orientation for the mounting rail is predetermined.

[0009] A disadvantage of these known solutions is the complete lack of flexibility regarding the orientation of the support rail. Instead, the support rail has a predetermined orientation, thus limiting the capabilities of the existing mounting device. Furthermore, this solution is relatively complex in terms of assembly and the design of the individual components. This solution requires significant time and expense for assembly. Additionally, the flexibility and selection of potentially usable mounting devices are restricted due to the fixed orientation of the support rail.If the orientation direction for the support rail specified by the mounting device is not suitable for the structural conditions of the roof on which the corresponding solar module is to be mounted, then the mounting device is simply unsuitable for this use and a user must resort to other, usually even more complex, mounting devices.

[0010] The object of the invention is to provide an improved solution for mounting accessory devices on buildings with regard to the disadvantages discussed above, which in particular offers a higher degree of flexibility with regard to the specific arrangement of the accessory device and thus more diverse application possibilities.

[0011] This problem is solved by an assembly device, an assembly system, and an assembly arrangement according to the independent claims. Advantageous embodiments of the invention are the subject of the dependent claims. REVELATION OF THE INVENTION

[0012] The invention relates to a mounting device for mounting a support element of an accessory device to a mounting surface of a building. The mounting device comprises a base element and a coupling element connectable to the base element, wherein the base element can be attached to or fixed to the mounting surface and the support element can be coupled or connected to the coupling element, so that in a mounted state of the mounting device the support element can be fixed on the mounting surface in a selected orientation direction with respect to the mounting surface.

[0013] In particular, the support element is a profile rail, and the accessory device is a solar module or solar collector. The mounting surface is specifically a roofing element such as a roof tile or a wall or (flat) roof section of the building, such as a wall or roof mounting base. When the mounting device is installed, the base element and the coupling element are connected to each other, the base element is attached to the mounting surface, and the support element is coupled to the coupling element. The connection between the mounting surface, base element, coupling element, and support element is preferably positive-locking and / or force-locking and is detachably connected using fasteners such as screws.

[0014] According to the invention, the assembly device comprises a connecting element with a base side facing the base element and a coupling side facing the coupling element, wherein the coupling element and the base side can be attached or fastened to the base element in at least one defined or definable respective connection position on the coupling side, so that the base element can be indirectly connected or connected to the coupling element by means of the connecting element, wherein at least one of the respective connection positions can be changed in such a way that at least two different orientation directions of the support element, in particular offset by 90° to each other, can be selectively realized.

[0015] In other words, the invention provides that, in the assembled state, the assembly device allows for one of at least two different orientations or alignments of the support element. During assembly, it is possible to select which of the at least two alignments is to be ultimately implemented. This selection is based on the realized connection position. In this respect, at least two different (final) connection positions are possible. The (final) connection positions can refer to the corresponding connection position of the connecting element and the base element, as well as to the corresponding connection position of the connecting element and the coupling element. Thus, at least two different base connection positions and / or at least two different coupling connection positions are possible.By selecting the connection position during assembly, the orientation direction of the support element can ultimately be selected or determined, since the realized connection position directly affects the associated orientation direction, or rather, orientation direction and connection position are linked.

[0016] Advantageously, the mounting device according to the invention allows for a high degree of flexibility with regard to the mounting and alignment of the support element and thus the accessory device, since, unlike known solutions, at least two different orientations of the support element can be achieved using the same mounting device. A further advantage lies in the time, effort, and cost savings associated with this flexibility. Furthermore, the mounting device according to the invention is designed to be comparatively simple, and its handling is correspondingly simplified.

[0017] As a rule, accessory devices, particularly in the form of solar modules or solar collectors, are not square but rectangular with a length-to-width ratio, since a greater number of accessory devices can be accommodated depending on their orientation on the mounting surface. The orientation of the accessory devices is generally determined by the orientation of the support element on the mounting surface. According to a preferred embodiment, it can be provided that in a first respective connection position and associated first orientation direction, a transverse arrangement of the support element on the mounting surface is possible, and in a second respective connection position and associated second orientation direction, a longitudinal arrangement of the support element on the mounting surface is possible, preferably angled at 90° from the transverse arrangement.Other angle values, for example between 70° and 110°, can be used for angling; however, it is essential that an essentially orthogonal decoupling of the mounting directions can be provided. In other words, the mounting device allows the support element to be positioned either longitudinally or transversely on the mounting surface. In longitudinal orientation, the support element is aligned lengthwise to a major dimension of the mounting surface; in transverse orientation, it is aligned perpendicular to this dimension. The choice of orientation depends on the prevailing mounting conditions, or rather, the optimal orientation is selected based on these conditions. Advantageously, the orientation direction can thus be adapted very flexibly to the prevailing mounting conditions, making the mounting device particularly versatile.

[0018] According to a preferred embodiment, the base element may have a base surface assigned to the base side of the connecting element, which is rotationally symmetrical of at least order four, and the base side of the connecting element may have a base connecting surface that is essentially complementary to the base surface, wherein at least two orientation elements spaced apart from each other along the perimeter of the surface are arranged on the base surface, wherein at least two connecting recesses extending through the base connecting surface and spaced apart from each other are formed in the base connecting surface along the perimeter, wherein, in order to adjust the connection position of the base side on the base element, in particular the base connection position, each orientation element of the base element may be fixedly connected to one of the connecting recesses of the connecting element.In particular, the base surface is circular or square. Preferably, the orientation elements and the connection recesses are each evenly spaced from one another. In particular, the orientation elements are designed as connecting elements such as threaded studs or threaded holes, and the connection recesses as connecting holes or connecting slots. Preferably, the orientation elements can be connected to their respective associated connection recesses by means of a screw connection. In particular, connection recesses arranged on each half of the base connection surface are always assigned to the same of the two orientation elements; that is, all connection recesses located on the first half belong to the first orientation element, and all connection recesses located on the second half belong to the second orientation element. By selecting orThe assignment of the connection recesses or orientation elements used for assembly allows for the selection of the final or realized connection position and thus the orientation direction. Advantageously, this makes selecting the desired connection position or orientation particularly simple and efficient, while simultaneously ensuring a mechanically stable and durable connection.

[0019] According to a preferred embodiment, the connecting recesses can be designed as slots, so that the connection position of the base side on the base element, in particular the base connection position, can be continuously adjusted at least in the range of 0° to 90°, preferably from 0° to 120°, by rotating the connecting element relative to the base element about a central circular axis. In particular, the connecting recesses are designed as arc-shaped slots. The rotation is accompanied by the selection or adjustment of the final connection position and thus the orientation direction. Preferably, in this case, the connection position of the coupling element on the connecting element, in particular the coupling connection position, remains unchanged or always the same.If the connecting element rotates due to the adjustment of the (base) connection position, the coupling element and thus the attached support element also rotate. Advantageously, stepless rotation of the arrangement or orientation of the connecting element on the base element is possible, allowing selection of the connection position or orientation direction. In particular, a further advantage is that this allows for the compensation of play or inaccuracies in the individual elements of the assembly device.

[0020] According to a preferred embodiment, the orientation elements can be designed as threaded studs or threaded holes, each having at least a partial thread. The threaded studs are either glued into recesses in the base surface or screwed into the threaded holes as an internal thread that is glued or milled into the base surface. It is also conceivable to screw fastening screws into the threaded holes for securing the elements. In other words, the orientation elements are manufactured as separate components connected to the base surface. This advantageously allows for a high degree of flexibility in material selection for the base element and the orientation elements, which can be manufactured from different materials. This can reduce manufacturing costs.Depending on the choice of material and the resulting different coefficients of thermal expansion, the further advantage of tolerance compensation may also arise.

[0021] As an alternative to the separate production of the base element and orientation elements, these can be manufactured as a single unit. This advantageously simplifies production.

[0022] According to a preferred embodiment, the coupling side of the connecting element may have a connecting support oriented perpendicular to the mounting surface for connecting the coupling element to the connecting element, in particular by at least a positive and / or force-fit connection. The coupling element can be slid or clamped onto the connecting support. The connecting support is preferably designed as a projection extending substantially perpendicularly from the coupling side. Advantageously, this allows for simple connection or coupling of the coupling element to the connecting element.

[0023] According to a preferred embodiment, the connecting carrier may have at least one guide element for the guided alignment of at least one section of the coupling element and / or a mounting slot for horizontally adjusting the coupling element relative to the mounting surface by means of a locking element. In particular, the guide element is designed as a guide groove or guide rib. The coupling element is specifically clamped or clampable, or slid or slideable onto the connecting carrier. The locking element is specifically a clamping screw. The guide element enables simple and secure positioning of the coupling element, in particular a positive-locking fastening. The mounting slot, in conjunction with the locking element, enables a force-fit securing of the coupling element, including the possibility of tolerance compensation.Instead of a single cross-section, multiple holes can be provided, allowing for incremental adjustment of the mounting height. This advantageously enables a simple, mechanically robust, and secure connection between the coupling element and the connecting element.

[0024] According to a preferred embodiment, the coupling element may have a connecting section associated with the connecting element, in particular its connecting support, for connecting the coupling element to the connecting element, and a support section associated with the support element for attaching the support element to the coupling element, wherein the connecting section and the support section are offset from each other by 90° via an angular segment. The preferably right-angled offset allows for horizontal alignment of the coupling element with respect to the base element, and the support element can be fixed to the coupling element with a displacement of 90° relative to this, thus essentially decoupling the mounting directions. Advantageously, this ensures – from a spatial perspective – a structural or mechanical decoupling of the degrees of freedom in the X and Y directions.

[0025] According to a preferred embodiment, the connecting section of the coupling element may have at least one counter-guidance element complementary to the guide element for guided alignment on the connecting element, and a locking recess extending through the connecting section for locking the connecting section to the connecting element by means of a locking element. In particular, the counter-guidance element is designed as a guide rib or guide groove. The alignment is specifically performed along the connecting element. The connecting section is specifically slid or clamped onto the connecting element. Advantageously, the counter-guidance element enables a particularly simple and precise connection of the coupling element to the connecting element, and the locking recess allows for subsequent secure locking, resulting in a secure and mechanically robust connection.

[0026] According to a preferred embodiment, the support section of the coupling element may have a support slot for vertically adjusting the support element relative to the mounting surface. The support element can be secured to the support section by a securing element extending through the support slot. Instead of a support slot, a plurality of support bores may be provided, allowing for stepless adjustment. In particular, the securing element is a clamping screw. The securing element is guided in a groove of the support element. Preferably, a surface of the support section facing the support element has a surface profile that engages with a form-complementary surface profile of the support element to counteract longitudinal displacement of the support element within the support slot.The slotted design allows for some play in the final fixing position, which advantageously compensates for tolerances and enables particularly precise positioning and locking of the support element. Furthermore, the combination of the slotted hole and the through-reaching fixing element is a mechanically and technically simple design that nevertheless ensures a high degree of safety and stability. If the support element can be guided within the support groove, the advantage of tolerance compensation is further enhanced. The surface profiling provides additional security regarding the durability of the fixing.

[0027] According to a preferred embodiment, the base element, the connecting element, and / or the coupling element can be made of an aluminum material, preferably by a die-casting process. Advantageously, the correspondingly designed components of the assembly device are thus lightweight, durable, weather-resistant, and cost-effective.

[0028] In a subordinate aspect, the invention relates to a mounting system for mounting at least one accessory device, in particular a solar module, on at least one mounting surface. The mounting system comprises at least the mounting surface, in particular a roofing element, preferably a roof tile, or a wall or roof section, preferably a wall or roof mounting base, and at least one mounting device that can be mounted on or is mounted on the mounting surface. It is proposed that the mounting device be designed according to the invention as described above. The advantages already mentioned above arise in this regard.

[0029] According to a preferred embodiment, the base element of the mounting device can be permanently connected to the mounting surface. In particular, the base element is formed integrally with the mounting surface. In this case, the mounting surface and the base element are inseparably connected and made of the same material. Advantageously, this ensures a particularly stable and therefore robust arrangement or connection between the mounting surface and the base element, and simplifies manufacturing.

[0030] As an alternative to a one-piece design, the base element can be detachably attached to the mounting surface. The attachment can be form-fit, force-fit, and / or material-fit, for example, by means of a snap-fit ​​connection, screws, and / or adhesive. In this case, the mounting surface and the base element are made of different materials. The advantage of the detachable connection is that the base element can be easily replaced, for example, in the event of damage.

[0031] According to a preferred embodiment, at least one support element for carrying an accessory device, in particular a solar module, is included, wherein the support element is arranged between the accessory device and the mounting device for the indirect attachment of the accessory device to the mounting device. Preferably, the support element is designed as a profile rail. In particular, the support element or the profile rail has a mounting groove that can be attached to or is attached to the coupling element and an accessory groove angled at right angles to this groove and that can be attached to or is attached to the accessory device. Preferably, the support element is manufactured by an extrusion process. The support element thus serves mechanically as a link between the mounting device and the accessory device to be mounted, which can therefore be mounted on the mounting surface by means of the mounting device.Advantageously, an easy-to-assemble, mechanically stable and safe mounting option for the accessory device is guaranteed.

[0032] In a further subordinate aspect, the invention relates to a mounting arrangement comprising at least one accessory device, in particular a solar module, and at least one mounting system, wherein the accessory device can be mounted or is mounted on at least one mounting surface by the mounting system. It is proposed that the mounting system be designed according to the invention as described above. The advantages already mentioned above arise in this regard. DRAWINGS

[0033] Further advantages become apparent from the accompanying drawing description. The drawings illustrate exemplary embodiments of the invention. The drawing, the description, and the claims contain numerous features in combination. A person skilled in the art will expediently consider the features individually and combine them into meaningful further combinations.

[0034] They show: Fig. 1A and Fig. 1B Each a perspective view of an advantageous assembly system with an advantageous assembly device, Fig. 2. A perspective view of a base element of the mounting device. Fig. 3A and Fig. 3B each a perspective view of a connecting element of the assembly device, Fig. 4A and Fig. 4B each a perspective view of a coupling element of the assembly device, Fig. 5A and Fig. 5B each shows a perspective view of a support element of the assembly system, and Fig. 6A and Fig. 6B each shows a perspective view of several combined assembly devices or assembly systems,

[0035] In the figures, similar elements are numbered with the same reference symbols. The figures merely show examples and are not to be understood as limiting.

[0036] Fig. 1A and Fig. Figure 1B shows a perspective view of an advantageous mounting system 10. The mounting system 10 serves to, or is designed to, attach an accessory device, in particular a solar module, which is not shown in detail here for the sake of clarity, at least indirectly to a mounting surface 12 of a building.

[0037] According to the present embodiment, the mounting surface 12 is a roofing element in the form of a roof tile. Alternatively, the mounting surface 12 can also be a wall or roof section of the building.

[0038] The mounting system 10 comprises at least one support element 14 and at least one mounting device 16. The support element 14 serves to carry the accessory device, which can therefore be attached to the support element 14 at least indirectly. The mounting device 16 serves to indirectly connect the support element 16 to the mounting surface 12 or to attach and / or secure the support element 14 with the accessory device arranged thereon to the mounting surface 12.

[0039] The mounting device 16 comprises a base element 16, a coupling element 20, and a connecting element 22. The base element 18 is arranged directly on or attached to the mounting surface 12 and connected to the coupling element 20 by means of the connecting element 22. The support element 14 is arranged on or attached to the coupling element 20.

[0040] In the Fig. 1A and Fig. In the assembled state of the mounting device 16 shown in Figure 1B, the support element 14 is aligned with the mounting surface 12 in a selected orientation direction and fixed to the mounting surface 12. In the Fig. In the illustration shown in 1A, the support element 14 is oriented transversely to the mounting surface 12, so that in Fig. 1A shows a cross-laying as the selected orientation direction. In the Fig. In the illustration shown in 1B, the support element 14 is aligned lengthwise to the mounting surface 12, so that it is in the Fig. The orientation shown in 1B indicates a longitudinal occupancy.

[0041] In the assembled state of the mounting device 16, the base element 18 and the coupling element 20 can each be connected to or attached to the connecting element 22 in at least one defined or definable connection position. Thus, the base element 18 can be attached to the connecting element 22, and vice versa, in at least one base-connection position. The coupling element 20, in turn, can be connected to the connecting element 22 in at least one definable coupling-connection position. Therefore, in the connected state, i.e., when the respective connection position is realized, the base element 18 and the coupling element 20 can be indirectly connected to each other via the connecting element 22.

[0042] In the present assembly system 10 or assembly device 16, it is advantageously provided that at least one of the respective connection positions, i.e., the base connection position and / or the coupling connection position, can be modified such that at least two different orientation directions of the support element 14, in particular those offset by 90° to each other, can be selectively realized. In other words, unlike known solutions, the present assembly system 10 or assembly device 16 allows both the Fig. The cross-stack shown in 1A, as well as the one in Fig. The longitudinal configuration shown in Figure 1B can be implemented optionally. Thus, it is intended that, depending on requirements, both orientations of the support element 14 can be realized using the same assembly device 16, meaning the implemented orientation can be selected. During assembly, it can be selected which of the at least two orientations should be ultimately implemented. The corresponding selection depends on the respective connection position of base element 18 and connecting element 22 and / or coupling element 20 and connecting element 22 achieved during assembly, since the connection positions are linked to the orientations. Therefore, at least two final connection positions are possible with regard to the base connection position and the coupling connection position.

[0043] According to the present embodiment, the connection position of base element 18 and connecting element 22, i.e., the base connection position, is variable to select the orientation direction of the support element 14. The connection position of coupling element 20 and connecting element 22, i.e., the coupling connection position, is, however, essentially unchangeable or remains constant. Therefore, in this case, the base connection position is changed to select the orientation direction, as will be discussed in more detail below.

[0044] Fig. Figure 2 shows a perspective view of the base element 18, which is arranged on the mounting surface 12. In this case, the base element 18 and the mounting surface 12 are formed as a single piece. Alternatively, the base element 18 can also be detachably attached to the mounting surface 12 by means of a force-fit, form-fit, and / or material-fit connection. The base element 18 has a base surface 24, which in this case is planar and circular, and which is associated with or points towards the connecting element 22. In this respect, the base surface 24 serves to connect the base element 18 to the connecting element 22, with the connecting element 22 being arranged and attached to the base surface 24. At least two orientation elements 26, spaced evenly apart along the circumference of the base surface 24, are arranged on the base surface 24 and extend substantially perpendicularly away from or project from the base surface 24.The orientation elements 26 serve to at least form-fittingly connect connecting element 22 and base element 18.

[0045] The orientation elements 26 are designed as threaded studs and each has at least a partial screw thread, which, after the base element 18 and the connecting element 22 have been joined, serves to secure the connection, for example, by means of nuts. The connection and securing of the base element 18 and the connecting element 22 will be explained in more detail later. The orientation elements 26, designed as threaded studs, are glued into recesses in the base surface 24. Alternatively, the threaded studs can also be screwed into the recesses, with the threaded studs and recesses having correspondingly complementary internal and external threads, respectively. Alternatively, the threaded studs or orientation elements 26 and the base surface 24 or the base element 18 can be formed integrally with each other.

[0046] Fig. 3A and Fig. Figure 3B each shows a perspective view of the connecting element 22, where in Fig. 3A a top view of a bottom side associated with the base element 18 and in Fig. Figure 3B shows a top view of the upper side of the connecting element opposite the lower side and associated with the coupling element 20.

[0047] As in Fig. As shown in Figure 3A, the connecting element 22 has on its underside a base side 27 associated with the base element 18 or its base surface 24, with a base connecting surface 28 that is essentially complementary to the base surface 24, i.e., also circular, for alignment or congruent arrangement on the base surface 24. Two connecting recesses 30, extending through the base connecting surface 28 and spaced evenly apart from each other, are formed along the perimeter of the base side 27 or base connecting surface 28. As shown in Figure 3A, the connecting element 22 has a base side 27 that is essentially complementary to the base surface 24, i.e., also circular. Fig. As can be clearly seen in Figure 3A, the connecting recesses 30 are designed as arc-shaped connecting slots or elongated holes. The connecting recesses 30 or connecting slots, in conjunction with the orientation elements 26, serve to connect the base element 18 and the connecting element 22 in a form-fit manner and simultaneously to adjust the connection position or base-connection position.

[0048] To connect the base element 18 and the connecting element 22, the connecting element 22 is placed with its base connection surface 28 onto the base surface 24, with the orientation elements 26 extending through or being inserted into the connection recesses 30. Thus, for connection and for adjusting the connection position or base-connection position, each orientation element 26 is fixedly connected to one of the connection recesses 30. Due to the slot-shaped design of the connection recesses 30, the connecting element 22, in the position connected to the base element 18, can be continuously rotated about a central circular axis at least in the range of 0-90°, preferably between 0-120°. The orientation elements 26 slide along or within the arc-shaped slots of the connection recesses 30 during the rotation. This possibility of rotation allows the connection position to be adjusted.Base connection position adjustable. Since, as mentioned previously, the connection position of coupling element 20 and connecting element 22, i.e., the coupling connection position, remains unchanged, changing the base connection position, i.e., rotating the connecting element 22 relative to the base element 18, results in a change in the orientation of the support element 14, which is indirectly connected to the connecting element 22 via the coupling element 20. This leads to the previously mentioned variation or selection of the orientation direction of the support element 14. In other words, the support element 14 is fixedly connected to the connecting element 22 via the coupling element 20. The orientation of the connecting element 22 relative to the base element 18 can, in turn, be varied by rotation to adjust the orientation direction of the support element 14.Once the intended final base connection position has been set, it can be fixed, as mentioned above, by fixing the orientation elements 26 that extend through the connection recesses 30, in particular by means of a nut pushed onto the external thread.

[0049] As in the Fig. As shown in the top view of the upper side of the connecting element 22 opposite the underside or base side 27 in Figure 3B, the connecting element 22 has a coupling side 32 on its upper side, facing or associated with the coupling element 20. The coupling element 20 can be attached or fixed to the connecting element 22 and connected to it on the coupling side 32. The coupling side 32 has a connecting support 34 that is oriented perpendicular to the mounting surface 12 when the mounting device 16 is installed as intended. As shown in Fig. As can be clearly seen in Figure 3B, the connecting beam 34 extends essentially perpendicularly from the coupling side 32 and is designed as a projecting projection. The connecting beam 34 serves to connect the coupling element 20 to the connecting element 22, at least by positive and / or force-fit connection, whereby the coupling element 20, as will be explained in more detail later, can be slid onto the connecting beam 34 and thus onto the connecting element 22, and can be fastened to the connecting beam 34 in the slid-on state.

[0050] The connecting beam 34 has at least one, and in this case two, guide elements 36, which are designed as guide ribs or guide projections extending from the side surfaces of the connecting beam 34. The guide elements 36 serve to align at least one section of the coupling element 20 in a guided manner. In other words, the coupling element 20 can be slid onto the connecting beam 34 by means of the guide elements 36.

[0051] Furthermore, the connecting carrier 34 has a mounting slot 38, which serves to horizontally adjust the coupling element 20, which is slid onto the mounting surface 12 during intended assembly. A locking element (not shown in detail), in particular a clamping screw, is provided for this purpose, by means of which the coupling element 20 can be fixed or fastened in the slid-on position. For example, a threaded bolt can be pushed through the mounting slot 38 and through another hole in the coupling element 20 arranged in alignment with it, and then secured on one or both sides by means of a nut in the pushed-through position.

[0052] Fig. 4A and Fig. Figures 4B each show a perspective view of the coupling element 20, where in Fig. 4A a first embodiment and in Fig. Figure 4B shows a second embodiment of the coupling element 20. Both embodiments have the same essential components and differ only in minor details of the specific arrangement or orientation of other non-essential components. The following description of the coupling element 20 is therefore applicable analogously to both embodiments.

[0053] The coupling element 20 has a connection section 40 assigned to the connecting element 22, specifically the connecting support 34. By means of the connection section 40, the coupling element 20 can be connected to the connecting element 22 by sliding it onto the connecting element 22 or its connecting support 34, as already described above.

[0054] The coupling element 20 further comprises a support section 42 associated with the support element 14, to which the support element 14 can be fixedly attached. This, among other things, effectes the previously discussed connection of the individual components of the mounting device 16, namely the base element 18, the coupling element 20, and the connecting element 22, and thus the connection of the support element 14 with the mounting surface 12.

[0055] As in Fig. 4A and Fig. As can be clearly seen in Figure 4B, the connecting section 40 and the support section 42 are offset from each other by 90° via an angled section 44. This 90° offset allows for horizontal alignment of the coupling element 20 relative to the base element 18, while the support element can be fixed to the coupling element 20 with a 90° displacement relative to it, thus providing decoupling of the mounting directions. This ensures structural and mechanical decoupling of the respective degrees of freedom in the X and Y directions.

[0056] The connecting section 40 has two counter-guiding elements 46, which are complementary to the guide elements 36 of the connecting carrier 34 and are thus designed as complementary guide grooves. The counter-guiding elements 46, in conjunction with the guide elements 36, serve to align the coupling element 20 on the connecting element 22 or its connecting carrier 34, as previously mentioned. Therefore, when the connecting section 40 is slid onto the connecting carrier 34, the coupling element 20 is guided by the interlocking of the guide elements 36 and counter-guiding elements 46 and thus securely positioned on the connecting element 22.

[0057] The coupling element 20, or connecting section 40, further comprises a locking recess 48 extending through the connecting section 40, which serves to lock the coupling element 20 to the connecting element 22. More precisely, the locking recess 48, in conjunction with the mounting slot 38 of the connecting carrier 34, allows the connecting section 40 to be fastened or locked to the connecting carrier 34. As mentioned previously, a locking element, not shown in detail here, can be used for this purpose. When the connecting section 40 is slid onto the connecting carrier 34, the guidance provided by guide elements 36 and counter-guide element 46 ensures that the mounting slot 38 and the locking recess 48 are aligned. The design of the mounting slot 38 as an elongated hole allows for a certain degree of play.A variation in the alignment allows for the compensation of any tolerances. Once the final alignment is achieved, connecting section 40 and connecting beam 34 are fixed together using the locking element.

[0058] The coupling element 20, or rather its support section 42, further comprises a support slot 50, which serves to fix the support element 14 vertically relative to the mounting surface 12. When installed as intended, the support element 14 can be positioned in the area of ​​the support section 42. Once the desired position is reached, the support element 14 can be fixed to the support section 42 by means of a fixing device, which is not shown in detail here for the sake of clarity. The fixing device is fixed to the support element 14, preferably guided within or along the support element 14, and is designed such that, once the support element 14 is positioned on the support section 42, it extends through the support slot 50.The fixing element extending through the support slot 50 can subsequently be secured or fixed in the desired position, for example, by means of a clamping screw. Due to its elongated design, the support slot 50 allows for a certain amount of play in the passage of the fixing element, thus compensating for any tolerances. Therefore, the support element 14 can be precisely aligned vertically relative to the mounting surface 12 by means of the support slot 50, and the final fixing position can be adjusted.

[0059] Optionally, a surface of the support section 42, which is assigned to the support element 14, can have a surface profile 56 that engages with a shape-complementary surface profile 56 of the support element 14 in order to counteract lateral displacement of the support element 14 in the support slot 50. The surface profile, which is located in the Fig. The structure shown in 4a to 5b can, for example, be designed as a groove structure, whereby the groove structure of the support element 14 can interlock with a groove structure of the support section 42.

[0060] Preferably, at least one of the components of the mounting device 16, i.e., the base element 18, the coupling element 20 and / or the connecting element 22, is made of an aluminum material, preferably by a die-casting process. This makes the mounting device 16 lightweight yet mechanically robust.

[0061] Fig. 5A and Fig. Figure 5B shows a detailed view of support element 14. Fig. 5A is a perspective view of a section of the support element 14 and in Fig. 5B shows a cross-section through the support element 14.

[0062] In this case, the support element 14 is designed as a profile rail and, as previously mentioned, serves to support the accessory device. When installed as intended, the support element 14 is positioned between the accessory device and the mounting device 16, as shown, for example, in Fig. 1A and Fig. 1B already shown, arranged so that the accessory device is indirectly arranged or attached to the mounting device 16 and thus to the mounting surface 12 by means of the support element 14.

[0063] The support element 14 has a fastening groove 52 that can be attached to the coupling element 20 or its support section 42. This groove serves to fasten or at least guide the support element 14 to the coupling element 20. In particular, the aforementioned fastening means for securing the support element 14 to the coupling element 20 can be guided in the fastening groove 52. Furthermore, the support element 14 has an accessory groove 54 angled at right angles to the fastening groove 52. This accessory groove can be connected to the accessory device or serves to fasten the accessory device to the support element 14. Preferably, the support element 14 is manufactured by an extrusion process, resulting in a simple and cost-effective manufacturing method.

[0064] Fig. 6A and Fig. Figure 6B shows a combination of several of the previously described assembly devices 16 or one or more assembly systems 10. Fig. 6A is the one that was previously discussed using the following: Fig. 1A discussed cross-stacking and in Fig. 6B which was previously based on Fig. 1B discussed longitudinal occupancy shown.

[0065] As in the Fig. 6A and Fig. As can be clearly seen in Figure 6B, a single support element 14, or alternatively several support elements 14, is uniformly aligned with respect to several mounting surfaces 12 by several mounting devices 16. Therefore, the Fig. 6A shows an orientation direction of the support element 10 perpendicular to the mounting surface 12, and in the case of Fig.6B around an orientation direction longitudinal to the mounting surface 12. Thus, by means of a combination of mounting devices 16 or mounting systems 10 according to the invention, a building area having several mounting surfaces 12, in particular a roof covered with a multitude of roof tiles, can be equipped with several accessory devices. The previously discussed diverse tolerance compensation options of the individual mounting devices 16 advantageously enable highly precise alignment of the support elements and thus a high-quality assembly result.
