The object of the invention consists in particular in providing a generic device with improved properties in terms of stability and simple assembly. The object is achieved according to the invention by the features of claim 1, while advantageous refinements and developments of the invention can be found in the dependent claims.

Advantages of the Invention

The invention is based on a façade device with at least one holding element, which is intended to hold at least one façade element in at least one assembled state, the holding element being designed as an elongate element, with at least one element perpendicular to a longitudinal direction of the The cross-sectional area of the holding element aligned with the holding element has at least two closed, at least essentially ring-shaped partial areas, with at least one section of one of the partial areas simultaneously forming another section of another of the partial areas, with the partial areas being arranged one above the other or next to one another.

It is proposed that the holding element has at least one recess which is provided for receiving the facade element, the holding element having at least one open partial area in the area of the recess, the recess defining a holding area of the holding element, the cross-sectional area being in a cut outside of the Holding area of the holding element has at least two essentially ring-shaped partial areas, wherein the holding element comprises at least one first wall and a second wall arranged on the first wall, which are designed as part of the at least two essentially ring-shaped partial areas, wherein the first wall and the second wall each extend at least substantially completely over a maximum extent of the holding element in the longitudinal direction, with the exception of the recess delimited by the holding element.

A configuration of this type can increase the stability of the holding element and simplify assembly of the holding element. A rigidity of the holding element can advantageously be increased and bending of the holding element can be avoided. Preferably, forces acting on the holding element, in particular shearing forces, can be compensated. A required number of connections, in particular screw connections, can be reduced to an assembly of the holding element.

The holding element is designed as an elongate element. An "elongated element" is to be understood in particular as an element in which an imaginary cuboid, which just accommodates the element, has a length which is at least twice, preferably at least five times and particularly preferably at least ten times the width and height of the blocks. The holding element is advantageously formed at least essentially, in particular completely, from a metal. Alternatively and/or additionally, the holding element could have at least one fiber-reinforced plastic, for example fiberglass and/or carbon fiber. In particular, the holding element has at least one holding area, which forms a, preferably form-fitting, common connection with at least one corresponding support area of the facade element. For example, the holding area could be designed as a projection and/or hook and/or teeth of the holding element. For example, the common connection could be designed as a plug connection and/or screw connection and/or snap connection. The holding element preferably has a multiplicity of holding regions which are arranged distributed in particular at regular distances from one another along the longitudinal direction of the holding element.

In particular, the facade element is designed as a panel-shaped element. A "plate-shaped element" is to be understood in particular as an element in which an imaginary cuboid, which just accommodates the element, has a length and width which are at least twice, preferably at least five times and particularly preferably at least ten times the height of the square. The facade element is advantageously formed at least essentially, in particular completely, from a metal. Alternatively and/or additionally, the facade element could have at least one metal composite material and/or at least one fiber-reinforced plastic, for example fiberglass and/or carbon fiber. For example, the support area could be designed as a recess. The facade element preferably has a bearing area on at least two opposite sides of the facade element, which in particular each extend over the entire side. At least one is particularly preferred the bearing areas of the facade element in the installed state have a common connection with at least one corresponding bearing area of a further, in particular adjacent, facade element.

In this context, a “ring” is to be understood in particular as a two-dimensional surface which has at least one closed inner edge and at least one closed outer edge. The fact that the partial area is "at least essentially ring-shaped" should be understood in this context to mean in particular that the partial area surrounds at least one point outside of the partial area by at least 270°, preferably at least 300° and preferably at least 330°. The partial area preferably has an angular, in particular rectangular, course. Alternatively, the partial area could have a curved, in particular circular, course. It would be conceivable for the sub-area to have at least one interruption at which an inner edge of the sub-area and an outer edge of the sub-area meet.

“Provided” is to be understood in particular as being specially designed and/or equipped. The fact that an object is provided for a specific function is to be understood in particular to mean that the object fulfills and/or executes this specific function in at least one application and/or operating state.

The facade device is preferably provided for holding and/or fastening facade elements to an object, such as a building wall. In particular, the facade device is designed differently from a device for holding or fastening windows. The facade device is preferably intended to fasten facade elements to the object in a vertical orientation. Particularly preferably, the holding element is intended to be arranged, in particular in the assembled state, in such a way that the longitudinal direction is aligned at least essentially parallel to a perpendicular direction. In particular, the holding element is provided for a vertical arrangement on the object.

Furthermore, it is proposed that the cross-sectional area has at least one closed annular partial area. The fact that the sub-area is “closed ring-shaped” is to be understood in this context in particular as meaning that the sub-area is free of discontinuities and surrounds at least one point outside the sub-area to 360°. In this way, in particular, the stability of the holding element can be further increased. External forces acting on the holding element can advantageously be distributed along the entire cross-sectional area. Weak points in the cross-sectional area, which are susceptible to deformation when external forces act, can be avoided in a particularly advantageous manner.

Furthermore, it is proposed that the partial area has at least one connection point. A "connection point" is to be understood in particular as a spatial area in which two materially separate sections of the partial area are connected to one another. For example, the connection point can have at least one welded seam and/or at least one soldered seam and/or at least one press fit and/or at least one bonding agent. This can in particular simplify production of the holding element without reducing the stability of the holding element. Advantageously, the holding element can be produced by bending a plate-shaped blank and still have a cross-sectional area with a closed ring-shaped partial area by subsequent grouting of interruptions in the cross-sectional area.

In an alternative embodiment of the invention, it is proposed that the partial area is free of connection points. In particular, the entire partial area is made of the same material. In this way, in particular, the stability of the holding element can be further increased. Structural weak points of the holding element produced by connection points can advantageously be dispensed with. A weakening of the material of the partial area can be avoided particularly advantageously by a connection process.

It would be conceivable for the facade device to have at least one fastening element which, in the installed state, overlaps the holding element on one side and could be designed in particular as a holder and/or a bracket and/or preferably as an L-bracket. In order to further simplify assembly of the holding element, it is proposed that the façade device has at least one fastening element which, in the assembled state, engages over the holding element on at least two, preferably exactly two, opposite sides of the holding element. The holding element is preferably in the assembled state fastened to the fastening element by at least one screw connection, for example by means of a self-drilling screw. Alternatively and/or additionally, the retaining element could be attached to the attachment element in the assembled state by at least one plug-in connection, a rivet connection, a clinch compression, a bolt connection and/or a snap connection. The fastening element is particularly preferably designed as an advantageously angular U-bracket. Stable attachment of the holding element can advantageously be achieved by a single attachment element and assembly of the holding element can be further simplified. A number of screw connections by which the holding element is fastened can be reduced in a particularly advantageous manner. Alternatively and/or additionally, the fastening element could have additional, L-shaped areas, as a result of which the fastening element essentially has the shape of an H bracket. The fastening element preferably rests against the holding element on the side on which the fastening element in particular overlaps the holding element. The fastening element is preferably provided to overlap the holding element, in particular in the mounted state, on two sides, in particular facing away from one another, with the fastening element in particular bearing, in particular exclusively, on the two sides of the holding element.

In a section outside of holding areas of the holding element, the cross-sectional area has the at least two essentially ring-shaped partial areas. In particular, the cross-sectional area can have any number of essentially ring-shaped partial areas. It would be conceivable for the ring-shaped partial areas to make contact with one another. The ring-shaped partial areas are preferably formed at least partially in one piece with one another. In this context, the fact that the ring-shaped partial areas are “at least partially formed in one piece with one another” should be understood to mean that at least one section of one of the partial areas simultaneously forms another section of another of the partial areas. For example, a wall of one of the partial areas can simultaneously be another wall of another of the partial areas. Particularly preferably, the cross section is in the form of at least two rings, preferably angular, stacked on top of one another. In particular, the holding element can be designed as a tube with at least one wall element arranged inside the tube. In this way, in particular, the stability of the holding element can be improved even further. Advantageous a rigidity of the holding element can be largely maintained even if one of the partial areas is bent.

It would be conceivable for the partial areas to be designed differently from one another. In order to simplify production of the holding element, it is proposed that the partial areas are at least essentially identical to one another. The fact that the partial areas are "at least essentially identical to one another" should be understood in this context to mean in particular that the partial areas are congruent to at least 70%, advantageously to at least 80% and preferably to at least 90% of their area. Advantageously, a number of partial areas can be varied in a simple manner by designing the holding element as a tube and dividing it evenly by any number of wall elements.

The cross-sectional area has the at least two closed, annular partial areas. In this way, in particular, the stability of the holding element can be further increased. External forces acting on the holding element can advantageously be distributed along the entire cross-sectional area. Weak points in the cross-sectional area, which are susceptible to deformation when external forces act, can be avoided in a particularly advantageous manner.

The holding element is preferably formed at least partially, in particular completely, by an extruded profile. The holding element is advantageously formed entirely by an extrusion process. In this way, production of the holding element can be simplified in particular. A number of process steps for producing the holding element can advantageously be reduced. A configuration of the holding element can be varied particularly advantageously in a simple manner. It would also be conceivable for the holding element to be formed by an extrusion process and at least one subsequent fastening process for fastening at least one wall element.

It would be possible for the at least one recess to be produced by a stamping process and a subsequent bending process. In order to enable flexible production of the holding element, it is proposed that the recess, which is provided for receiving the facade element, preferably at least one bearing area of the facade element and particularly advantageously a bearing area of a further facade element corresponding to the bearing area, is produced by a laser process. Alternatively and/or additionally, the recess could be produced by a plasma process and/or water jet process and/or erosion process and/or milling process and/or punching process. The recess defines the holding area, advantageously completely. The holding element has the open partial area in the area of the recess. The fact that the recess is produced in a “laser process” is to be understood in this context in particular as meaning a process in which the recess is produced by cutting out a section of the holding element using a laser cutter. Advantageously, a configuration of the recess can be varied in a simple manner; in particular, no mechanical adjustments to a production device are necessary for this. The recess can also be produced particularly advantageously after a folding process, a profiling process or an extrusion process. In particular, the recess extends at least essentially perpendicular to the longitudinal direction of the holding element. Preferably, the recess produced by a thermal cutting process, in particular the laser process or a plasma process, or the punching process, in particular with a continuously constant shape, extends at least essentially completely over a maximum transverse extension of the holding element, in particular the partial area or partial areas, which in particular at least is aligned substantially perpendicular to the longitudinal direction.

Furthermore, it is proposed that the holding element comprises the at least one first wall and the second wall arranged on the first wall, which are formed as part of the at least one essentially ring-shaped partial area or the at least two essentially ring-shaped partial areas, with the first wall having a has an average wall thickness that is greater than an average wall thickness of the second wall. An advantageously reinforced wall for carrying facade elements on the holding element can be achieved, with the first wall in particular being a wall carrying the facade elements can be trained. An advantageously stable facade can be made possible. It can be an advantage low weight and advantageously low material costs of the retaining element can be achieved, in particular since the second wall, which is less stressed than the first wall, can advantageously be made thin. In particular, the first wall and/or the second wall are/is at least largely at least essentially planar. The first wall and/or the second wall preferably extends/extends at least for the most part, in particular at least essentially completely, over a maximum extent of the holding element in the longitudinal direction. The average wall thickness of the first wall preferably has a value from a value range between 2 mm and 5 mm, preferably between 3 mm and 4 mm and preferably at least essentially 4 mm. The average wall thickness of the second wall preferably has a value from a value range between 1 mm and 2 mm, preferably between 1.5 mm and 2 mm and preferably at least essentially 2 mm. It is conceivable that the mean wall thickness of the first wall is at least essentially twice the mean wall thickness of the second wall. Preferably, the first wall and/or the second wall each have a maximum wall thickness and/or a minimum wall thickness which deviates from the mean wall thickness of the first wall or the second wall by at most 10%, preferably at most 5% and preferably at most 3%. The fastening element preferably overlaps the holding element in the region of the second wall, in particular around two second walls which are aligned at least essentially parallel to one another. In particular, the essentially ring-shaped partial area is formed from four walls, in particular two at least essentially identical first walls and two at least essentially identical second walls. The first wall is preferably intended to carry and/or support at least a large part of the weight of the facade element in at least one assembled state.

In addition, it is proposed that the first wall is aligned at least for the most part at least essentially perpendicular to the second wall and at least essentially parallel to the longitudinal direction of the holding element. An advantageously high stability of the holding element can be achieved. The first wall preferably extends at least essentially completely over a maximum transverse extent of the holding element, which in particular extends at least essentially perpendicularly extends to the longitudinal plane arranged. Preferably, the maximum transverse extent of the holding element forms one side of an imaginary cuboid, which just about completely encloses the essentially ring-shaped partial area in the cross-sectional area of the holding element oriented perpendicularly to the longitudinal direction. The second wall preferably extends at least essentially completely over a maximum further transverse extension of the holding element, which extends in particular in the plane arranged at least essentially perpendicularly to the longitudinal direction. In particular, the maximum further transverse extent of the holding element is aligned at least essentially perpendicularly to the maximum transverse extent of the holding element. The first wall preferably delimits the recess(es) at least partially. The recess(es) is/are preferably arranged at least partially, in particular for the most part, on the first wall. The first wall is preferably arranged on a side of the holding element which faces the facade element. The first wall is preferably arranged at least essentially parallel to the facade element when the facade device is in a mounted state. In particular, a main plane of extent of the first wall is arranged at least essentially parallel to a main plane of extent of the facade element in the assembled state of the facade device. In particular in one configuration of the facade device with at least two essentially ring-shaped partial areas, the first wall, in particular viewed in the cross-sectional area of the retaining element perpendicular to the longitudinal direction, is aligned at least essentially perpendicular to a straight line running through the midpoints of the two partial areas. The two partial areas are preferably each formed together by a second wall on one of two sides facing away from one another. In particular, the two second walls extend over a maximum transverse extent of the two partial areas, which in particular is aligned at least essentially parallel to the straight line running through the center points of the two partial areas. First walls, in particular three first walls, and second walls, in particular two second walls, of the holding element preferably form the at least two essentially ring-shaped partial regions. In particular, a first maximum transverse extent of the two partial areas, in particular aligned at least essentially perpendicularly to the longitudinal direction, corresponds to a maximum extent of the individual first walls. In particular, one corresponds, in particular at least substantially perpendicular to the longitudinal direction and at least in Substantially perpendicular to the first maximum transverse extent, second maximum transverse extent of the two partial areas of a maximum extent of the individual second walls.

Furthermore, a facade, in particular a building facade, is proposed with at least one facade device according to the invention and with at least one facade element according to the invention. As a result, the stability of a holding element of the facade device can be increased and assembly of the holding element can be simplified. A rigidity of the holding element can advantageously be increased and bending of the holding element can be avoided. Preferably, forces acting on the holding element, in particular shearing forces, can be compensated. In a particularly advantageous manner, the number of connections required, in particular screw connections, for mounting the holding element can be reduced.

Description of the exemplary embodiments

figure 1 shows a sectional view of a facade 32a. The facade 32a is designed as a house facade. Alternatively, the facade 32a could be designed as a building facade for any other type of building. The facade 32a has a facade device 10a. The facade device 10a is in an assembled state. The facade 32a has a multiplicity of facade elements 14a, 16a which are identical to one another. Alternatively, the facade elements 14a, 16a could be designed differently from one another. Of the objects that are present several times, only those objects that are necessary for the description of the figures are provided with a reference number in the figures. The facade elements 14a, 16a are arranged one above the other and together form an outer surface of the facade 32a. For reasons of clarity, only one facade element 14a and another facade element 16a of the facade elements 14a, 16a are described below. The further facade element 16a is arranged adjacent to the facade element 14a.

figure 2 shows the facade element 14a in a more detailed sectional view from the side. The facade element 14a is designed as a plate-shaped element. The facade element 14a is made entirely of metal. Alternatively and/or additionally, the facade element 14a could have at least one fiber-reinforced plastic, for example fiberglass and/or carbon fiber. The facade element 14a has an upper support area 34a. The upper support area 34a is designed as a folded upper edge of the facade element 14a. Alternatively, the upper bearing area 34a could only have parts of the upper edge of the facade element 14a. The facade element 14a has a lower bearing area 36a. The lower support area 36a is designed as a folded lower edge of the facade element 14a. Alternatively, the lower bearing area 36a could only have parts of the lower edge of the facade element 14a. The facade element 14a has two covering areas 60a, only one of which in figure 2 is visible. The covering areas 60a are designed as lateral folds of the facade element 14a. The covering areas 60a serve to laterally close off a space spanned by the facade element 14a. Alternatively, the facade element 14a could also be free of covering areas.

The facade device 10a has a multiplicity of holding elements 12a which are identical to one another. The holding elements 12a are fastened parallel to one another at regular intervals on a house wall 46a (see figures 5 and 6 ), the fastening of the holding elements 12a being explained in more detail later. Alternatively, the holding elements 12a could be arranged at irregular distances from one another. The holding elements 12a are arranged in a vertically aligned manner. Alternatively, the holding elements 12a and/or facade elements 14a could also be arranged in a horizontally aligned manner. For reasons of clarity, only one holding element 12a of the holding elements 12a is described below. The holding element 12a holds the facade element 14a and the other facade element 16a. The holding element 12a is formed by an extruded profile.

figure 3 shows the holding element 12a in a more detailed representation obliquely from the side and with a section through the holding element 12a running perpendicularly to a longitudinal direction 40a of the holding element 12a. The holding element 12a has a partition wall 44a. The partition wall 44a is made of the same material as a remaining holding element 12a. The partition wall 44a extends over the entire extent of the holding element 12a along the longitudinal direction 40a. The partition wall 44a divides an interior space of the holding element 12a into two partial spaces of equal volume. Alternatively, the partition wall 44a could divide the interior space into two partial spaces with different volumes. Alternatively, the partition wall 44a could only extend over part of the extension of the holding element 12a along the longitudinal direction 40a. Alternatively and/or additionally, the holding element 12a could have any number of further partitions.

The holding element 12a has a cross-sectional area 18a running perpendicular to the longitudinal direction 40a. The cross-sectional area 18a has a partition cross-sectional area 24a. The cross-sectional area 18a has a partial area 20a. The cross-sectional area 18a has a further partial area 22a. Alternatively and/or additionally, the cross-sectional area 18a could have any number of further partial areas and/or partition cross-sectional areas or no partition cross-sectional area and only one partial area. The partial areas 20a, 22a are arranged one above the other. Alternatively, the partial areas 20a, 22a could be arranged next to one another. The partial areas 20a, 22a are partially formed in one piece with one another. The further sub-area 22a is of identical design to the sub-area 20a, which is why only the sub-area 20a is described below. Alternatively, the partial areas 20a, 22a could be designed differently from one another. The partial area 20a is designed as a closed, ring-shaped partial area. Alternatively, the partial area 20a could have at least one interruption. The portion 20a is free of splices. The portion 20a has the partition wall cross-sectional area 24a. The partial area 20a encloses one of the partial spaces of the interior. The portion 20a is formed as an angular ring. Alternatively, the portion 20a could be formed as a curved ring.

The holding element 12a comprises three first walls 62a and two second walls 64a arranged on the first walls 62a, which are designed as part of the at least two essentially ring-shaped partial regions 20a, 22a, the first walls 62a each having an average wall thickness 66a which is greater is than an average wall thickness 68a of the second walls 64a. The first walls 62a and the second walls 64a are of at least essentially planar design.

The first walls 62a and the second walls 64a each extend, in particular with the exception of recesses 30a delimited by the holding element 12a, at least essentially completely over a maximum extent 70a of the holding element 12a in the longitudinal direction 40a. The average wall thickness 66a of the first walls 62a has a value from a value range between 2 mm and 5 mm, preferably between 3 mm and 4 mm and preferably at least essentially 4 mm. The average wall thickness 68a of the second walls 64a has a value from a value range between 1 mm and 2 mm, preferably between 1.5 mm and 2 mm and preferably at least essentially 2 mm. It is conceivable that the mean wall thickness 66a of the first wall 62a is at least essentially twice as great as the mean wall thickness 68a of the second wall 64a. Preferably, the first walls 62a and the second walls 64a each have a maximum wall thickness that deviates from the mean wall thicknesses 66a, 68a of the first walls 62a and the second walls 64a of at most 10%, preferably at most 5% and preferably at most 3% %, having. In particular, the essentially ring-shaped sections 20a, 22a are formed from the three first walls 62a and the two second walls 64a, with the first walls 62a in particular being arranged between the two second walls 64a viewed along the longitudinal direction 40a. The first walls 62a are preferably provided to carry and/or support at least a large part of the weight of the facade elements 14a arranged, in particular fastened, on the holding element 12a in at least one assembled state.

The first walls 62a are at least for the most part aligned at least essentially perpendicular to the second walls 64a and at least essentially parallel to the longitudinal direction 40a of the holding element 12a. The first walls 62a preferably extend at least essentially completely over a maximum transverse extension 72a of the holding element 12a, which extends in particular in a plane arranged at least essentially perpendicularly to the longitudinal direction 40a. The maximum transverse extent 72a of the holding element 12a preferably forms one side of an imaginary cuboid which just about completely encloses the essentially ring-shaped partial regions 20a, 22a in the cross-sectional area 18a of the holding element 12a oriented perpendicularly to the longitudinal direction 40a. The second walls 64a preferably extend at least substantially completely over a maximum further transverse extension 74a of the holding element 12a, which extends in particular in the plane arranged at least essentially perpendicularly to the longitudinal direction 40a. In particular, the maximum further transverse extent 74a of the holding element 12a is aligned at least essentially perpendicularly to the maximum transverse extent 72a of the holding element 12a. In a mounted state of the facade device 10a, the first walls 62a are arranged at least essentially parallel to the facade elements 14a arranged on the holding element 12a. In particular, a main plane of extent of the first walls 62a is arranged at least essentially parallel to a main plane of extent of the facade elements 14a arranged on the holding element 12a in the assembled state of the facade device 10a. The first walls 62a are, in particular viewed in the cross-sectional area 18a of the holding element 12a oriented perpendicularly to the longitudinal direction 40a, oriented at least essentially perpendicularly to a straight line running through midpoints of the two partial regions 20a, 22a. The two partial regions 20a, 22a are each formed on one of two sides facing away from one another by a second wall 64a of the two second walls 64a. The two second walls 64a extend over a maximum transverse extent 74a of the two partial areas 20a, 22a, which in particular is aligned at least essentially parallel to the straight line running through the center points of the two partial areas 20a, 22a.

The holding element 12a has a multiplicity of recesses 30a which are identical to one another. The recesses 30a are formed at regular intervals from one another. Alternatively, the recesses 30a could be arranged at irregular distances from one another. For reasons of clarity, only one recess 30a of the recesses 30a is described below. The recess 30a accommodates the facade element 14a and the further facade element 16a, which in figure 4 is shown in more detail. The recess 30a is made by a laser process. Alternatively and/or additionally, the recess 30a could be produced by a plasma process and/or water jet process and/or erosion process and/or milling process and/or punching process. Alternatively, the recess 30a could be produced by stamping and folding. The recesses 30a each extend at least substantially perpendicular to the longitudinal direction 40a of the holding element 12a. Preferably, they extend through the laser process produced recesses 30a with a continuously constant shape at least essentially completely over the maximum transverse extension 72a of the holding element 12a, in particular the partial areas 20a, 22a, which is in particular aligned at least essentially perpendicular to the longitudinal direction 40a.

The first wall 62a preferably delimits the recess(es) at least partially. The recess(es) is/are preferably arranged at least partially, in particular for the most part, on the first wall 62a.
