The Kragprofil 160 connects to the attachment portion 150, which extends in particular transversely to this and projects, for example, substantially perpendicularly from the vertical attachment portion 150 .. Preferably, the Kragprofil 160 extends in the installed state substantially horizontally. The cantilevered profile (160) is connected to the mounting portion 150 at a first end and has a second end opposite the first end formed as a free end such that an intermediate portion 170 is located between the first and second ends is that extends in a distancing direction D from the mounting portion 150 or the first end away.

The free end of the Kragprofils 160 may be formed as a holding portion 180 such that it has seen in the course and in particular from the first end, following the intermediate portion a crank 181. A crank, also cranking or cranked construction designates a short jump on a component, ie a change in direction of a course axis.

The intermediate portion 170 is shaped and sized to provide a support surface 171 on a first side S1 of the mounting profile 140, corresponding to the support member 200 provided thereon. On the support surface 171 is located on the first side or above the Kragprofils (160) or above the intermediate portion 170 holding member 200, wherein the support surface 171, the support member 200 supports and carries. The rear side of the holding element 200, which is directed counter to the direction of distancing D and faces the fastening section 150, bears against a contact device or stop lip 173 (FIG. FIG. 2 ). The abutment device may be formed by a surface portion directed away from the attachment portion 150.

The abutment device or abutment lip 173 is formed or arranged on a stop web 172 which extends transversely to the intermediate section 170 or the cantilever profile 160 and which is connected to the intermediate section 170 or the cantilever profile 160. The abutment device or abutment lip 173 may in particular be formed or arranged horizontally, in particular on a stop web 172 which attaches vertically to the cantilever profile 160 ( FIG. 2 ). The stop web 172 extends on the first side of the mounting profile 140. By the coordinated dimensions or depths (ie lengths in the Distanzierungsrichtung D) of the support member 200 and the depth of the abutment device or abutment lip and positioning of the stop web (172) on the Kragprofils a precise alignment of the holding member 200 relative to the holding portion 180 of the mounting profile 140, in particular in the Distanzierungsrichtung D achieved.

( FIG. 3 )

The FIG. 4 shows in a side view how the free end of the Kragprofils 160 and the holding portion 180 is at least partially inserted into the groove 210 of a below the Kragprofils 160 or on the opposite side to the first side S1 of the mounting profile 140 located second side S2 holding member 200 is inserted or that the groove 210 of a holding element 200 arranged below the Kragprofils 160 at least partially surrounds the holding portion 180. The groove 210 may in particular be designed as a groove open to the first side of the mounting profile 140. The holding section (180) and the groove 210 are dimensioned such that the upper side of the holding element 200 facing the first side S1 on the underside of the Kragprofils160 facing the second side S2), the inner sides of the groove 210 on the outer region or the outer surface of the holding portion 180 and the directed against the Distanzierungsrichtung D back of the support member 200 at a below the Kragprofils 160 attaching, vertical or transverse to the intermediate portion 170 extending stop ridge or stop profile 174 at least partially rests.

In particular, it can be provided that the attachment portion 150, the Kragprofil 160, the stop bar 172 and the stop bar or the stop profile 174 is made as a piece or in one piece.

The FIG. 5 shows that the cross section of the adjoining the intermediate portion holding portion 180 has a to the first side of the mounting profile 140 toward or upwardly open guide 183 for receiving an end portion of a bolt 240. The cross section of the guide 183 and the cross section of the end portion of the bolt 240 are coordinated so that the latch 240 in the guide 183 horizontally or in or along the Distanzierungsrichtung D, ie in the plan view of the FIG. 5 in the depth or to the second side of the mounting profile 140, in installation position can be moved horizontally in the facade plane to the left and right, in its distance from the building in or along the Distanzierungsrichtung D little or no play has.

The guide 183 may in particular be designed as a groove open to the first side of the mounting profile 140.

The guide 183 opposite outer side of the holding portion 180 has a rounded outer profile or rounded edges. Thus, a first obliquely attached holding element 200 with engagement of the holding portion 180 in the groove 210 can still be twisted and aligned ( FIG. 6a ).

The outer edge of the holding portion 180 has a relation to the extent of the mounting portion 150 and with respect to the installed state with respect to the direction of gravity lower, ie in the direction from the first to the second side different level than the located on the first side top of the Kragprofils 160 and a level difference (dN), in order to enable a pivoting of a arranged above the Kragprofils holding member 200 problem-free. Furthermore, the holding section 180 may have a slight slope 190 in the region of the crank in order to be able to easily and efficiently raise a pivoting holding element 200 to the level of the supporting surface 171 of the cantilever profile 160 in order to then store it on the supporting surface 171 (FIG. Fig. 6b ).

The FIG. 7 shows a side view of a vertically arranged facade element (130) with two on vertical opposite edges of a facade element (130) fixed holding elements (200), for example by gluing, screwing, riveting, etc. The holding profiles (200) thereby comprise the facade element (130) at the edge and partly at the front.

In principle, however, other embodiments of a holding element are possible, in which a facade element only at the edge without enclosing to the front or it only held at the back.

The FIG. 8a shows an embodiment of a holding element 200 in the profile. As a rule, extrusion profiles made of aluminum are used to produce such profiles. Extrusion is a particularly suitable for aluminum forming process for producing also irregularly shaped profiles, ie elongated components with a same cross section over the length of the cross section, in which a compact is pressed by a die.

The holding element 200 produced in this way has a cross section with a particularly substantially rectangular basic shape with thin-walled webs or web sections 202, 203, 204, 215, 221, 222, 223 and a channel 230 which is partially open toward the outer contour of the retaining element 200 or a cavity 230. By correspondingly vertically arranged webs a to the outer contour of the retaining element towards open groove 210 is also formed. The holding element 200 with the web sections 202, 203, 204, 215, 221, 222, 223 can be produced as one or in one piece. In the state arranged on the Kragprofil 160 of the holding member 200, the groove 210 is open to the open side of the open guide 183 out ( FIG. 1 ).

Façade elements are usually thin cuboid or plate-shaped objects with a later in installation position in conjunction with other elements a facade forming the front, in a mounting position facing a building back and each right-angled, circumferential, connecting the front and back side surfaces or edges ,

The façade element extends in space in a plane, wherein in installation position, the totality of all installed facade elements form a façade level, which from a design point of view not necessarily all façade elements actually have to lie in one plane. In FIG. 8a the vertical profile of this facade level FE is indicated in the middle of the facade element 130. In particular, it can be provided that the facade plane results in the case of a series of adjoining façade elements 130 from the longitudinal extensions of the row of façade elements 130 arranged next to each other.

For fastening facade elements, the holding element 200 has a fastening section 220 for fastening a facade element 130 to the holding element 200 and a functional section 201 for fastening the holding element to the outer surface of a building.

In the illustrated embodiment, the attachment portion 220 includes a support web 211, an edge land 222, and a cladding ridge 223 that form a skirt that embraces a back, edge, and front of a cladding member 130 when the end portion of a cladding member 130 is received by the skirt is. The support web 211, the edge web 222 and the facade web 223 together form a substantially U-shaped enclosure, which opens transversely to the direction D in the installed state of the holding member.

When in the assembled state on the first side S1 of the mounting profile 140 located holding member 200, the U-shaped enclosure opens in a direction opposite to the direction of gravity, so that the enclosure receives the weight of each recorded Fasadenelements. In a holding state 200 located in the mounting state on the second side S2 of the mounting profile 140, the U-shaped enclosure opens in the direction of gravity, so that the enclosure receives an upper edge portion of the Fasadenelements with respect to the direction of gravity.

A facade element 130 is inserted into the enclosure formed by the webs or a holding element is pushed with this enclosure on the edge of a facade element and e.g. bonded.

At least one holding element 200 is mounted at least on the mutually opposite and transversely to the direction of distancing D or vertically spaced edges of a facade element 130 or a correspondingly long profile is used as a profile frame revolving around the facade element 130 (not shown here).

In the functional section 201 of a holding element 200 is in one of the Façade plane FE remote, parallel to the facade plane FE extending and Deten for Distanzungsrichtung D or in installation position towards the building further arranged substantially parallel to the back of a facade element 130 and the edge region of a facade element open towards groove 210. In this case, the groove 210 is formed from two parallel side webs, which extend to the first side or extend substantially vertically, and a horizontal web which attaches to one end of the side webs and connects them.

In the exemplary embodiment, the groove 210 is formed by a vertically extending support web 211, a horizontal base web 215 and a vertical channel web 203.

The groove 210 is dimensioned by width and depth so that a holding portion 180 of a mounting profile 140 can be at least partially introduced. The holding portion 180 is designed substantially U-shaped and is inserted with its closed part into the groove 210, so that the mutually oppositely located outer surfaces of the legs of the holding portion 180 between facing surfaces of the groove 210 is located, and this particular can be present.

The functional portion 201 further still has the channel 230, which is formed of two side bars 203, a support bar 202 and an interrupted cover web 204 and contributes to the stiffening while saving material. The channel 230 extends in the assembled state transversely to the direction of distancing and along the extent of the enclosure of the mounting portion 220. The channel 230 may be partially open or circumferentially closed. Angles inserted in such a channel 230 can be e.g. connect two holding elements each corner and it can be used to produce circumferential profile frame (not shown).

The FIG. 8b shows the side view of another embodiment of a holding element 200 with two smaller channels 230; wherein a channel 230 is adjacent to the attachment portion 220, and thus an outer wall of the support web 221 is, and centrally between the channels 230, the groove 210 is arranged.

The FIG. 8c shows the side view of another embodiment of a holding member 200 again with only one channel 230, wherein the channel 230 adjacent to the mounting portion 220 and the groove 210 in the mounting portion opposite the end of the holding member 200 is disposed

FIG. 8d shows a further embodiment of a holding element 200. For this purpose, a already used for the enclosure of solar modules holding profile 265 is supplemented with a clip 260 so that conventionally framed solar modules for use with the holding system according to the invention can be modified.

For this purpose, the clip 260 has in its profile a cover web 261 and an angled cantilever web 262 arranged on the cover web 261.

For assembly, the cantilever 262 is inserted through the opening 231 into the channel 230, so that the cover web 204 partially closing the channel 230 is covered by the cantilever 262 (FIG. Fig. 8e) ,

The clip 260 is further shifted until the Kragsteg abuts the inner wall of the channel 230 ( Fig. 8 f) ,

In this position, the latching web 263 snaps into the opening 231 of the channel 230, whereby the clip 260 is positively connected to the retaining profile 200 ( Fig. 8g ). In addition, to further secure a built-in clip also a locking element can be inserted axially into the channel 230, which blocks the cantilever element 262 in its voltage applied to the channel inner wall position and thus prevents release of the clip from the holding element (not shown).

A composite of retaining profile 265 and clip 260 produced in this way together forms a retaining element 200 with a fastening section 220 for receiving a facade element 130 and a functional section 201 for attachment to buildings. The necessary groove 210 is formed from a side surface of the holding profile 265 and the Nutsteg 215 and the side web 203 of the offset and angled profile of the clip 260 ( Fig. 8h) ,

Fig. 9a shows a further embodiment of a holding element 200 with a modified attachment portion 220, which has no front facade web, but a facade element 130 is supported only on a back with a support bar 221 and laterally on the edge with an edge web 222. A mounted with such holding elements facade would have a very uniform appearance, since on the facade only the facade elements 130 and the edge bars 222 would be visible.

Fig. 9b shows a further embodiment of a holding element 200 with a modified attachment portion 220, which starting from Fig. 8 b also has no peripheral edge web more, but a facade element is connected only at one rear with a support web 221. A mounted with such holding elements facade would have a very compact and uniform appearance, since no holding elements would be visible and the facade element could be mounted practically shock to impact or with minimal expansion joints. In particular, the facade elements could be mounted with their edges on the holding elements protruding (not shown here).

Fig. 9c shows a further embodiment of a holding element 200 with a modified attachment portion 220, which starting from Fig. 8c has an enlarged edge web 221 and so provides a larger area for attachment of a facade element and so even larger or heavier items can be securely attached.

The height of Kragpofils on which an upper facade element is turned off with a holding element and the opposite cause the lowering of the holding portion by the Kröpfung of the Kragprofils to the underside of the Kragprofils out a distance between vertically adjacent facade elements. In order to keep this distance as a visible gap small, one can provide a holding element with an offset, so that the edge of a facade element or its border protrudes beyond the support surface of the holding element and thus bridges the gap or reduces a gap ( Fig. 10 a) ,

The Fig. 10b shows the profile view of two holding elements in comparison, right in the image with an offset V by the support bar 202 against the outer contour of the Retaining element or the edge web 222 is set back, so that the edge web 222 protrudes with its outer edge above the level of the support web 202.

The Fig.10 c shows the profile view of two holding elements in comparison, right in the picture with an offset V by the Nutsteg 215 is set back relative to the outer contour of the support member or the edge web 222 in the extension direction of the facade element 130, so that the edge web 222 with its outer edge is lower than a Retaining element without such an offset.

The Fig. 11a to 10d shows an example of the installation of a facade element (130).

For this purpose, two mounting profiles 140 are mounted horizontally extending at a corresponding distance from each other on a base support 120. Between these mounting profiles 140, a facade element 130 is used with two holding elements (200) fastened to vertically opposite edges of the facade element (130).

In a first step ( FIG. 11b) the facade element (130) is pivoted relative to the façade plane (FE) and thus slightly obliquely to an upper mounting profile (140), wherein the holding element (200) with the groove (210) attached to the holding portion (180) or with the groove side surface groove side surface (212) is placed on the holding portion (180).

In a further step ( Fig. 11c) the facade element (130) is lifted slightly upwards so that the holding section (180) is at least partially inserted into the groove (210) or the holding element (200) snaps into place on the holding section (180).

Then, the facade element (130) in the façade level (FE) is pivoted back until it with the mounting profile facing back of the lower support member (200) on the vertical stop web (172) or on the horizontal stop lip (173) of the lower mounting profile (140 ) and is vertically aligned ( Fig. 11d ). In this case, the lower holding element (200) is supported with its underside on the support surface (171) of the lower mounting profile (140).

Finally, a latch (240) in the guide (183) of the holding portion (180) of the lower mounting profile (140) is inserted and horizontally in the façade level FE in the groove (210) of the holding element (200) inserted ( Fig. 11e) ,

As in Fig. 11i 2, the latch (240) has an L-shaped cross section with a long leg (241) and a short leg (242) with the L upside down. The long leg (241) is held by the guide (183) of the holding element (200) and faces upwards. The leg (241) is so long that it extends from the guide (183) of the holding section (160) out to the groove base (215) of the groove (210). The short end (242) points away from the façade element (130) in the direction of the building and is long enough to reach the building-side inner side (212) of the groove (210), so that the holding element (200) between the latch (240 ) and a stop surface (173) of the mounting profile (140) is clamped or mounted relative to the building, since it is now vertically fixed between the cantilevers (160) of the two mounting profiles (140) and due to the positive locking holding portion (180) , Holding element (200) and latch (240) can not solve.

The latch (240) may be displaced in the guide (183) either to the middle or to the opposite side of the facade element (130) and further latches (240) may be inserted. In an embodiment not shown here, the latch (240) in the guide (183) can be secured against inadvertent displacement, for example with a worm screw.

Another embodiment of a fastening system show the FIGS. 12a to 12e ,

Fig. 12a shows a side view of a modified mounting profile (140), wherein the holding portion (180) has a hook-shaped offset (181). In the region of the crank a horizontally extending spacer bar (182) is arranged. Approximately in material thickness of the wall of the holding element (200) to the offset (181) is spaced from the cranked, vertical holding portion (180), a parallel, above the Kragprofils (160) arranged, vertical stop web (172).

According to the profile of the mounting element is a holding element (200) used in which the channel (230) is arranged centrally between the fastening portion (220) and groove (210) and the groove (210) directly to the, the fastening portion (220) opposite end of the holding element (200). ( Fig. 12b )

In a first step ( Fig. 12c ), the facade element (130) is pivoted relative to the facade plane FE and thus slightly obliquely to a lower mounting profile (140) of two correspondingly spaced mounting profiles, wherein the lower support member (200) with the groove (210) on the hook-shaped holding portion (180) of Kragprofils (160) attached or with the groove (210) on the holding portion (180) is placed.

Subsequently, the facade element (130) is pivoted into the façade plane (FE), so that the outer side wall of the groove (210) or the lower holding element (200) between the free end of the hook-shaped holding portion (180) and the stop web (172) the lower mounting profile (140) is held, wherein the lower holding element (200) downwardly on the support surface (171) of the Kragprofils (160) is supported. ( Fig. 12d) , and the upper holding element with its upper mounting profile (140) facing back on a vertical, from the upper mounting profile (140) wegstehendes down stop profile (174) is applied ( Fig. 12e ).

In a next step ( Fig. 12 e) a further facade element (130) is set below the first façade element (130) in the façade plane (FE) such that the rear side of the upper holding element (200) of the further façade element (130) facing the mounting profile (140) is attached to a lower stop web (14). 172) of the now located in the middle between the two facade elements (130) mounting profile (140) is applied and the grooves (210) of the two now opposite holding elements (200) facing each other and are aligned. In this case, the upwardly open groove (210) of the lower holding element takes over the task of receiving and guiding the bolt (240).

Finally ( Fig. 12f ), an L-shaped latch (240) is inserted into the vertically aligned grooves (210) with mutually facing openings of the two opposing support members (200), the long leg (241) from the groove bottom (215) of the lower groove (210) to the groove bottom (215) of the upper groove (210) extends and the inside of the long leg (241) on the spacer web (182) of the holding portion (180) is applied, the outside of the L -shaped bolt (240) on the façade element side inner sides (211) of the grooves (210) of the two opposing holding elements (200) rests. The short leg (242) lies with its outer side against the groove base (215) of the lower holding element (200) and points away from the facade element (130) in the direction of the structure. He presses with its front side, the lower support member (200) against a vertically extending, below the Kragprofils (160) arranged stop profile (174) by the end face of the short leg (242) on the building side inside (212) of the groove (210) of the lower holding member (200) presses.

The cross-section of the L-shaped latch 240 may also be varied to increase the width of the long leg 241 and short leg 242 so that the inner sides of the long and short legs 241, 242 abut directly against the crank 181 of the retaining portion 180 , In this case, the holding section 180 has no spacer bar 182 ( Fig. 13 ). Thus, the inserted latch 240 fixes an upper holding element 200 in the normal to the facade plane FE and a lower holding element in the vertical. Since both corresponding facade elements are each connected on the opposite side with also locked retaining elements, the facade elements are mounted and locked.

For the completion of a final series of façade elements of a façade, a modified latch or clip is proposed.

Fig. 14 shows the profile of a bolt 240, in which on the long leg 241, a hook-shaped profile 243 is arranged, which engages from behind behind the cranked portion 181 of the holding portion 180 of the corresponding mounting profile 140 and locked in a form-fitting manner.

Alternatively, the use of a clip 250 is proposed, which is placed on the long leg 241 of the bolt 240 and from behind behind the cranked portion 181 of the holding portion 180 of the corresponding mounting profile 140 engages and positively locks ( Fig. 15 )

FIG. 16 shows a further embodiment of a fastening device according to the invention, wherein the holding elements 200 shown are assembled from conventional solar module frame and clips 260. Again, several, vertically stacked, horizontally extending rows of facade elements are provided here. In the side view, however, only two adjacent rows are arranged with an arranged between these rows over the entire width of a building extending mounting profile 140.

The crank 181 of the holding portion 180 of a first mounting profile 140 is executed here vertically above the Kragprofils 160 and forms outwardly a square contour. On this crank 181, a first facade element 130 is placed obliquely with its vertically lower edge and the retaining element 200 arranged there arranged and pivoted in the Fassendenebene until the groove 210 sits snugly on the crank 181 and fixed in a form-fitting manner. After pivoting the opposite edge of the element in the façade level is there to fix the facade element 130 there laterally, ie parallel to the façade level in the vertically upwardly open groove 210 and the vertically downwardly open guide 183 of the crank 181 another mounting profile 140, a bolt 240th inserted. The bolt fits largely free of play in the guide 183 and has a height corresponding to fix a facade element in the vertical. To likewise fill the groove 210 of the holding element 200 of the facade element to be fixed and thus fix free play at right angles to the facade plane laterally outside the guide 183 spacer lips 244 are provided, which extend to the lateral groove inner surfaces.

FIG. 17 shows a further embodiment. The mounting profile 140 has in its attachment portion 180 a hook-shaped offset with a vertically upwardly directed hook.

A first facade element 130 with its vertically lower edge and the holding element 200 arranged there is placed obliquely on this hook or offset 181 and pivoted into the façade plane until the groove 210 rests on the offset 181. For better storage, the holding portion has a spacer bar 182, so that the width of the groove 210 bridged and the holding member 200 is mounted largely free of play.

After pivoting the opposite edge of the element in the facade plane for fixing the facade element 130 there laterally, ie parallel to the façade level in the vertically upwardly open groove 210 of the upper holding member 200, a latch 240 is inserted. In this embodiment, the latch is cranked so that it pivots outside the groove and rests vertically from below on the mounting portion 180 of the mounting profile and the mounting portion 180 engages behind the building side and so that facade element 130 is fixed vertically and in the facade level.

The bar can also be self-fixed, e.g. via a steel pin 245, which is introduced via vertical joints.

Fig. 18 1 schematically shows a facade of a building 110 with vertical base supports 120, horizontally arranged mounting profiles 140 and a facade element 130 inserted between two mounting profiles 140, which is connected to a latch 240 inserted in a guide 183 or placed on a lower mounting profile 140 by horizontally displacing the bolt 240 is locked in the groove 210 of the lower holding member 200 of the facade element 130. The one or more bars preferably have a total length of about 1/20 to ½ the width of a facade element 130, more preferably 1/4. One or more bolts can be used.

An inserted bolt is moved with a thin tool from the front or from the side to the desired position. Where appropriate, it can be secured against further unintentional shifting, e.g. with a worm screw. Possibly. Additional bolts are used and pushed accordingly.

A possibly desired unlocking can be achieved by using a flat tool, the bolt from the engagement region of the holding element of a facade element horizontally in the facade plane to the left or right is pushed out.

The mounting elements as shown can also be rotated by 180 ° with a correspondingly adapted structure of a facade.
