Description

Title of the invention: System for cladding a projecting corner of a metal roof

[0001] The field of the invention is that of the design and manufacture of metal roofing equipment for buildings.

[0002] The invention relates more specifically to a system for covering the corners of metal roofs.

[0003] In the field of the invention, the projecting angles of the metal roof of a building must be dressed.

[0004] A salient angle corresponds for example to a ridge, or to a hip.

[0005] Conventionally, metal profile type claddings are used to cover the protruding angles.

[0006] Basically, a profile can simply be screwed onto the roof support to cover a protruding angle.

[0007] Fixing brackets specific to metal roofs are also known for fixing a metal profile type covering directly to the metal plates forming the roof covering, the assembly being designed to also allow ventilation of the metal roof.

[0008] Such fixing lugs are for example designed in two parts, the first of which is coupled to the end of a metal plate of a roof, and a second part is coupled to the cladding. The articulation between the two parts makes it possible to adapt to differences in inclinations between the edges of the sheet metal and that of the cladding.

[0009] This system previously described makes it possible to create a so-called "ventilated" cladding. In fact, the fixing lugs allow air to pass between the roof covering and the corner cladding.

[0010] Another type of ventilated ridge cladding is made from the grouping of two galvanized steel profiles.

[0011] A first profile forms a base coupled along the angle, on the roof support. More precisely, the first profile has a U-shaped section whose hollow is oriented towards the roof support. This first profile then has a plurality of openings regularly distributed along its upper edge to allow air to pass through.

[0012] A second profile, forming the cladding, is then coupled in an overlapping manner on the first profile using fixing lugs. This coupling is configured to allow air to pass between the two profiles.

[0013] Compared to the two solutions previously described, faster alternatives to implement, more intuitive and more versatile are sought.

[0014] Furthermore, particularly in relation to the ventilated ridge made of galvanized steel which particularly protrudes from a metal roof, a cladding system is sought which visually integrates better into a roof.

[0015] The invention aims in particular to meet the needs of the prior art, and to overcome the drawbacks of known solutions.

[0016] More specifically, the invention aims to propose a system for covering protruding angles of a metal roof which is quick to implement.

[0017] The invention also aims to provide such a system which makes it possible to cover different types of protruding angles of a metal roof.

[0018] The invention also aims to provide such a system which is visually integrated into the metal roof.

[0019] These objectives, as well as others which will appear subsequently, are achieved thanks to the invention which has as its subject a system for covering projecting angles, in particular ridges, of a metal roof, the roof being coupled to a support, the system comprising: - fixing legs; - a covering coupled to the fixing legs, characterized in that each fixing lug is composed of two fixing parts articulated relative to each other, and mounted so as to be disassemblable from each other, and in that each fastener comprises: - a coupling base designed to allow the coupling of the cladding; - a coupling foot on a part of the support, the coupling foot forming a means of angular positioning of the coupling base relative to the support.

[0020] Thanks to the system according to the invention, a solution is available that is quick to implement and versatile.

[0021] Indeed, in the case of covering a ridge or a hip of a roof with two slopes, the system, thanks to its fixing bracket with two articulated fixing parts, adapts while respecting the inclinations of each of the slopes of the roof.

[0022] Indeed, each of the fixing pieces is coupled to the roof support, for example battens, which allows the coupling base of each fixing piece to have its own predetermined inclination relative to the support, and thus relative to the slopes of the metal roof.

[0023] By being articulated to each other, the inclination of the two fixing parts of a fixing lug are independent of each other.

[0024] In the case where the roof has a single slope, then the two fixing pieces can be disassembled from each other to be used separately. The support for the cladding is then suitable for roofs with a single slope.

[0025] Such a simple slope corresponds to a wall ridge and a roof with a single slope.

[0026] Finally, the fixing of the fixing parts, along a ridge for example, makes it possible to have a plurality of coupling bases, on which it is sufficient to simply couple the cladding. This solution is thus particularly simple and intuitive to implement by a roofer.

[0027] Finally, the system allows the cladding to be visually integrated into a roof due to the respect of the slopes thanks to the fixing lugs.

[0028] Advantageously, for each fixing part, the coupling foot has a flat bearing surface against the support, the coupling foot being screwed onto the support.

[0029] In this way, when coupling the coupling foot to the support, then the flat bearing surface comes into flat contact against the support and the fixing part adopts the predetermined inclination that it must take with respect to this support and the roof covering that this support supports.

[0030] According to a preferred characteristic, for each fixing part, the coupling base is formed by a plate having a flat upper surface.

[0031] Following the coupling of the fixing part to a support, the plate has a predetermined inclination relative to the shape of the part, and in particular depending on the configuration of the coupling foot.

[0032] Accordingly, a fixing bracket has two plates inclined relative to each other depending on the supports on which the fixing parts are fixed.

[0033] This forms a coupling base particularly suitable for coupling a covering.

[0034] Advantageously, for each fixing part, the tray has a front part designed to overhang the upper end of a metal slope of the roof, the cladding being coupled to the fixing part by having a return hooking a free end of the front part of the tray.

[0035] The visual integration of the cladding on the metal roof is optimized.

[0036] In fact, the fixing lugs are then embedded in the cladding, and do not protrude from an external face of the cladding.

[0037] Preferably, each fixing part comprises an elastic return member designed to tend to move the covering apart, the covering being clipped onto the fixing lugs.

[0038] The coupling of the cladding is thus carried out in a particularly easy, simple and quick manner for a roofer to implement.

[0039] In fact, it is then sufficient to push the covering onto the fixing lugs to achieve the clipping.

[0040] The elastic return members then push the covering back to keep it clipped.

[0041] According to a preferred solution, each fixing lug comprises means for locking an angle formed between the two fixing parts.

[0042] Following the coupling of each of the fixing pieces and the locking of the angle formed between the two fixing pieces, each fixing lug is anchored in a durable manner on the metal roof.

[0043] In addition, it is ensured that the inclination between the two fixing parts is maintained over time. This ensures that the covering is permanently held on the fixing lugs.

[0044] According to a preferred design, each fastening piece provides an air passage between the roof and the cladding, and the system comprises closures positioned in the air passage and coupled to the fastening pieces.

[0045] Ventilation is thus permitted thanks to the system.

[0046] Preferably, the closures are formed by combs having teeth extending from the cladding towards the roof.

[0047] Such combs make it possible to simply form means for preventing the passage of water likely to pass through the air passage, and for preventing the passage of insects.

[0048] Preferably, the teeth are elastically deformable.

[0049] In this way, when installing the system the teeth of the comb can come into contact against the metal roof, and they then adopt their own position without preventing the correct installation of the comb.

[0050] In addition, such elastically deformable teeth allow the position of the teeth to be adapted to elements of the metal roof such as standing seams between two metal plates. In this case, the teeth are positioned on either side of the standing seam.

[0051] Advantageously, the closures are clipped onto the fixing parts.

[0052] In this way the closures are installed particularly quickly and easily on the fixing parts.

[0053] Other characteristics and advantages of the invention will appear more clearly on reading the following description of different preferred embodiments of the invention, given as illustrative and non-limiting examples, and the appended drawings among which: • [Fig.l] [Fig.l] is a schematic perspective representation of a metal roof implementing a system for covering projecting angles according to the invention; • [Fig.2] [Fig.2] is a schematic representation of the detail identified by the reference II on [Fig.l]; • [Fig.3] [Fig.3] is a schematic representation of a cross-section of the dressing system according to the invention; • [Fig.4] [Fig.4] is a schematic perspective representation from above of a fixing lug of the covering system according to the invention; • [Fig.5] [Fig.5] is a schematic representation seen from the side of a leg for fixing the cladding system according to the invention; • [Fig.6] [Fig.6] is a schematic perspective representation of below a fixing part of a fixing lug as well as a closure associated with the fixing part.

[0054] With reference to figures 1 to 3, a system 1 for covering projecting angles of a metal roof 10 is shown.

[0055] The metal roof 10 is coupled to a support 11.

[0056] This support 11 can for example correspond to beams, as well as to assemblies of battens, or even to boarding.

[0057] According to the embodiment illustrated by [Fig.l], the metal roof 10 comprises two slopes 100.

[0058] Each slope 100 is formed from a plurality of plates 101 joined to each other by standing seams 102.

[0059] The two slopes 100 extend towards each other up to an upper end of the metal roof 10.

[0060] A salient angle is thus formed which must be dressed. In this case, this salient angle is a ridge.

[0061] System 1 allows this angle to be dressed.

[0062] With reference to Figures 2 to 6, the system 1 comprises: - fixing lugs 2 intended to be coupled to the support 11 of the metal roof 10; - a covering 3 coupled on the fixing legs 2.

[0063] According to the present embodiment, the system 1 further comprises closures 4 positioned in an air passage provided between the cladding 3 and the metal roof 10.

[0064] Each fixing lug 2 is composed of two fixing pieces 21.

[0065] According to the present embodiment, the two fixing parts 21 are identical. from each other.

[0066] These fixing parts 21 are articulated relative to each other, and are also mounted to be disassemblable from each other.

[0067] In other words, the two fixing parts 21 of a fixing lug 2 can be assembled together, then disassembled.

[0068] By being articulated relative to each other, the two fixing pieces 21 can have their inclination modified relative to each other.

[0069] More specifically, each fixing part 21 comprises: - a coupling base 22 designed to allow the coupling of the covering 3; - a coupling foot 23 on a part of the support 11.

[0070] The coupling base 22 of each fixing part 21 is formed by a plate 220.

[0071] This plate 220 notably has a flat upper surface 221.

[0072] According to the present embodiment, by being articulated to each other the angle formed by the flat upper surfaces 221 of the plates 221 can form an acute angle of between 89° and 175°.

[0073] When coupling a fixing part 21 to a part of the support 11 via the coupling foot 23, then the coupling base 22 adopts a predetermined inclination relative to the support 11.

[0074] Consequently, the coupling foot 23 forms a means for angular positioning of the coupling base 22 relative to the support 11.

[0075] More specifically, the coupling foot 23 predetermines the angular positioning of the plate 220 forming the coupling base 22 relative to the support 11 on which the coupling foot 23 is fixed.

[0076] As can be seen in Figures 3 to 5, the coupling foot 23 extends from the plate 220 in a direction transverse to the flat upper surface 221.

[0077] The coupling foot 23 has a flat bearing surface 231. This flat bearing surface 231 is intended to be positioned against the support 11.

[0078] When fixing the fixing part 21 by its coupling foot 23 on the support 11, then the support surface 231 forces the positioning of the fixing part 21 by forming a plane contact against the support 11.

[0079] The coupling foot 23 is coupled to the support 11 by being screwed onto the support 11.

[0080] Indeed, as can be seen in [Fig.4], the plate 220 has holes 230 allowing the insertion of screws, and the screwing of these screws into the support 11 through the coupling feet 23.

[0081] With reference to Figures 2 to 5, the tray 220 has a front portion 222 which is designed to overhang the upper end of a metal slope 100 of the roof 10.

[0082] The plate 220 also has a joining part 223 intended to come into contact with the other joining part 223 of the plate 220 of the second fixing part 21 of the fixing lug 2.

[0083] The plate 220 extends between the junction portion 223 and the front portion 222.

[0084] This plate 220 has in this case a rectangular shape between the part of junction 223 and the front part 222.

[0085] As can be seen in Figures 2 and 3, the covering 3 is coupled to the fixing part 21 by a free end 2220 of the front part 222 of the plate 220.

[0086] More specifically, the cladding 3 is a metal profile. This metal profile can be made of different types of metal such as steel, aluminum, copper, stainless steel, titanium, zinc, etc.

[0087] The cladding 3 is a profile having a cross-section comprising a V-shaped part, having a first section 31 and a second section 32 forming an angle with respect to each other, as well as returns 33 folded towards the inside of the cladding 3 at the free ends of the first section 31 and the second section 32.

[0088] These folded returns 33 are designed to hook the free ends 2220 of the front parts 222 of the plates 220.

[0089] In other words, the covering 3 is embedded on the fixing lugs 2, thanks to the returns 33 hooked on the free ends 2220 of the plates 220.

[0090] Furthermore, as can be seen in Figures 2, 3, 4 and 5, each fixing part 21 comprises an elastic return member 24.

[0091] This elastic return member 24 is designed to tend to move the covering 3 away from the fixing lug 2.

[0092] Consequently, the covering 3 can be clipped onto the fixing lugs 21.

[0093] Indeed, it is sufficient to position the covering 3 against a fixing lug then to press on the covering 3 to crush it, deform it elastically, and make the returns 33 pass beyond the free ends 2220 of the front parts 222 of the plates 220.

[0094] Then, by releasing the covering 3, the elastic return members 24 push back the covering 3 causing the covering 3 to clip.

[0095] These elastic return members 24 take the form of tabs 240 projecting from the plates 220.

[0096] For information purposes, a 3-piece cladding may have a length of 2 meters.

[0097] Each fixing piece 21 of a fixing lug 2 further comprises arcuate arms 26 fitting into the arcuate arms 26 of the other fixing piece 21.

[0098] According to the present embodiment and with reference to [Fig.5], the arched arms 26 are divided into a solid upper arched arm 261 and a hollow lower arched arm 262.

[0099] The hollowed-out lower arcuate arms 262 of two fixing pieces fit into each other and define a passage inside which locking means 25 of the system can be inserted to lock the angle formed between the two fixing pieces 21.

[0100] These locking means 25 are for example formed by a bolt comprising a screw and a nut.

[0101] As previously mentioned, the system 1 comprises closures 4.

[0102] In fact, each fixing part 21 provides an air passage between the roof 10 and the cladding 3. The closures 4 make it possible to create a watertight seal and prevent the passage of insects.

[0103] These closures are coupled to the fixing pieces 21, and more specifically clipped onto the fixing pieces 21.

[0104] More specifically, the fixing parts 21 have elastically deformable hooks 27 each designed to allow the clipping of a closure 4.

[0105] These hooks 27 are positioned under the front parts 222 of the plates 220.

[0106] With reference to figures 2, 3 and 6, a closure 4 is formed by a comb 40.

[0107] This comb 40 has teeth 41 which extend from the cladding 3, towards the roof. 10.

[0108] In other words, the system is configured so that the teeth extend transversely, and more specifically orthogonally, to the metal roof 10.

[0109] The teeth 41 of the combs 40 are elastically deformable. These teeth 41 can for example be made of elastomer.

[0110] The comb 40 also has a bar 42 which carries the teeth 4L

[0111] The bar 42 extends longitudinally so as to form a long row tudinal of teeth 41 intended to extend parallel to the covering 3.

[0112] The bar 42 is clipped onto the hooks 27 of a fixing part.

[0113] For this purpose, the bar 42 has a groove in which the hooks 27 can to fit in.

[0114] The groove also makes it possible to adjust the respective positioning of the comb 40 relative to the fixing part 21.

[0115] As an indication, a comb can have a length of 2 meters.

[0116] The system 1 previously described forms a complete versatile solution for covering the protruding angles of a metal roof, in particular for ridges or hips. Its implementation by professional roofers is quick, intuitive, and allows a visually qualitative result to be obtained.
