Description

Technical Field

[0001] The present invention relates generally to a fixing device for roof tiles on pitched roofs, and more particularly to a fixing device for solar roof tiles on pitched roofs. Background Technology

[0002] When building a new house with a pitched roof or renovating an existing one, choosing "on-the-roof" solar roof tiles is a preferred option due to their aesthetic appeal. In this case, solar roof tiles serve a dual purpose: as a roof covering and as a power generation device. Typically, solar roof tiles are installed on the horizontal slats of the pitched roof using special fixing devices. These devices secure the solar roof tiles while also providing protection against water ingress and a drainage system for atmospheric water.

[0003] In the prior art, the fixing device for solar roof tiles is known.

[0004] Swisspearl Group AG's EP2784241A1, published in October 2014, relates to a roof covering consisting of lower and upper transversely connecting profiles, which are mounted and secured to a substrate, one higher than the other in the flow direction. A water tank is configured to collect water horizontally parallel to the substrate, and / or a seal located between the overlapping portions of the lower and upper panels is configured to be parallel to the substrate. The lower and upper panels are secured together by panel fasteners. The lower and upper panels overlap, so the descending edges of the panels overlap with the connecting profiles.

[0005] Centurywatt's WO12120208A2, published in September 2012, relates to a cover plate for a pitched roof panel, comprising: a frame extending along the direction of the roof's slope; and a plurality of photovoltaic panels arranged longitudinally and partially overlapping along the direction of the roof's slope, in which the lower edge of the top panel covers the upper edge of the bottom panel in a row. A key feature of this invention is that the upper edges of the photovoltaic panels are provided with seams that allow the photovoltaic panels to extend substantially in the same plane and seal the cover plate, said seams not directly contacting the entire width of the panels overlapping with the same seam. This invention is particularly suitable for standard laminated or double-glass photovoltaic solar panels. Summary of the Invention

[0006] In a preferred variation, a fixing device for solar roof tiles is provided, the device comprising a rectangular beam extending longitudinally (x) and including a first support member supported on a first upper slat of a pitched roof in the installation position. The rectangular beam is further supported in the installation position by a second support member on a second lower slat. To fix at least one solar roof tile, the fixing device further includes at least one bracket for the solar roof tile. In some variations, the bracket can fix two or more horizontally adjacent solar roof tiles. To prevent water ingress, a drainage channel is disposed adjacent to at least one bracket and extends longitudinally (x) to drain atmospheric water along the longitudinal outer edge of the solar roof tile.

[0007] Typically, the first and second supports each include at least one first support region that supports the rectangular beam substantially along a longitudinal direction x, generally perpendicular to the rectangular beam, relative to the first upper strip and the second lower strip. Alternatively, or further, the first and / or second supports may include at least one second support region that supports the rectangular beam along a longitudinal direction x, relative to the first upper strip and the second lower strip.

[0008] Depending on the application, the first and / or second support member may include at least one connecting device disposed in the respective first and / or second support area for securing the first and / or second support member to the respective first upper slat and / or the respective second lower slat. The connecting device may be selected from at least one of the following: screws, bolts, nails, pins, glue, slings, etc. The securing device can be fixed to various types of slats, such as curved metal slats; however, conventional wooden slats are preferred.

[0009] In a preferred variation, when perpendicular to the approximate extension direction x of the rectangular beam, the first support area of ​​the first support member is separated from the bracket by a first distance d1, and the first support area of ​​the second support member is separated from the bracket by a second distance d2, wherein the second distance d2 is greater than the first distance d1. This has the advantage that, when the solar roof tiles are arranged in the installation position, their lower ends are inclined relative to the plane defined by the first upper slat and the second lower slat. Preferably, the first support area is separated from the upper end of the rectangular beam by a third distance d3 in the installation position, and the second support area is separated from the lower end of the rectangular beam by a fourth distance d4 in the installation position, wherein the fourth distance d4 is greater than the third distance d3. A further advantage is that the rectangular beam includes a cantilevered portion that extends longitudinally x beyond the second lower slat at the installation position of the fixing device. The fixing device with the above structure allows rows of roof tiles, especially solar roof tiles and / or (ordinary) roof tiles, to overlap in the cantilevered portion of the rectangular beam.

[0010] A good effect is achieved when at least the second support member is firmly fixed to its respective second lower slat, while the first support member rests against the first upper slat. When the wind contacts the lower end of the fixing device, the fixing device converts the lifting force into pressure on the first upper slat in a rocker-like manner.

[0011] In a preferred variation, the rectangular beam has a C-shaped or U-shaped cross-section perpendicular to the longitudinal direction x in at least one region. To achieve a good weight-to-strength ratio, the rectangular beam is preferably made at least partially of stamped and bent sheet metal and / or injection-molded plastic material. These shapes and materials are advantageous because they allow for good weight and rigidity in the rectangular beam.

[0012] According to the design, the support structure can be interconnected as a separate component with the rectangular beam and / or solar roof tiles. Preferably, at least a portion of the support structure is made of a resilient material. Possible materials for the support structure include foam and rubber substrate. In some variations, the support structure can be shaped as a rubber pad. This rubber pad can be adhered to the rectangular beam.

[0013] Material-saving structures can be achieved when drainage channels are integrated into the brackets and / or rectangular beams. Preferably, multiple drainage channels are integrated into the brackets to provide intricate sealing and support for the solar roof tiles.

[0014] The fixing device may include at least one fastening element for securing the solar roof tile in its installation position along the longitudinal x-axis, said fastening element preferably being shaped as a hook attached to a rectangular beam. However, other types of fastening elements are also possible, such as eyelets and / or bolts and / or clips and / or adhesives. In some variations, the surface of the hook may be at least partially covered with an elastic material to protect the solar roof tile. Furthermore, the solar roof tile may be secured by the suspended portion of an ascendingly arranged fixing device.

[0015] Preferably, a spacer is provided between the suspended portion and the solar roof tile, the spacer being at least partially composed of an elastic material to limit the possible displacement of the solar roof tile toward the suspended portion.

[0016] When the spacer is used as a seal between the two, good results can be achieved.

[0017] Excellent results can be achieved when the spacer acts not as a seal, but as a water backflow baffle to block water flowing back due to wind, while providing at least one air gap to allow air to flow between the suspended roof tiles. This is advantageous because cooling of the solar roof tiles increases their power generation efficiency. In some variations, two or more water backflow baffles can be installed in the suspended section.

[0018] To prevent damage to the solar roof tiles, the mounting device preferably further includes ribs that extend between two adjacent solar roof tiles at an installation location adjacent to the drainage channel. This is advantageous, particularly when two solar roof tiles are arranged horizontally adjacent to each other, their respective longitudinal outer edges resting against a bracket of the mounting device positioned between them. The ribs are preferably made of a resilient material to protect the solar roof tiles from damage. In a preferred variation, the ribs may be integrally formed with the bracket; however, the ribs may be provided as separate components between two adjacent solar roof tiles. In this case, each of the two adjacent solar roof tiles is partially mounted on a bracket of the same mounting device positioned between the solar roof tiles, which further protects against atmospheric moisture intrusion.

[0019] Another aspect of the invention is a solar roof tile for covering a pitched roof, which is installed on the slats of the pitched roof by the aforementioned fixing device.

[0020] In one variation, the solar roof tile includes a strip-shaped sealing element extending parallel to at least one longitudinal or horizontal outer edge of the solar roof tile. A watertight seal can be achieved when the sealing element is positioned adjacent to the horizontal outer edge of the solar roof tile on the sun-facing side in its installation position, within an area shaded by the overhanging portions of adjacent solar roof tiles. In the area covered by the strip-shaped sealing element and / or in areas of the solar roof tile surface shaded by the overhanging portions of the mounting fixture located above, the solar roof tile preferably does not have solar cells.

[0021] In a preferred variation, the solar roof tile includes a water return baffle extending parallel to at least one horizontal outer edge of the solar roof tile. At the installation location of the solar roof tile, the water return baffle provides an air gap between the lower and upper solar roof tiles, allowing air to flow between them. This airflow cools the solar roof tile, thereby improving its efficiency. In this document, the amount of water that may enter the roof is minimized while providing air circulation to cool the solar roof tile. The water return baffle preferably has an L-shaped or triangular cross-section. In some variations, the water return baffle mechanically connects the lower solar roof tile to a suspended portion of the upper mounting fixture, thus restricting displacement of the solar roof tile towards the suspended portion of the upper mounting fixture. However, the water return baffle typically does not connect two adjacent solar roof tiles because it provides an air gap for air circulation.

[0022] Advantageously, the water return baffle is attached to the surface of the solar roof tile, adjacent to the horizontal outer edge of the solar roof tile. However, depending on the design, the water return baffle can also be attached to the horizontal outer edge of the solar roof tile. Typically, the water return baffle extends from the solar roof tile, forming a barrier to stop water from flowing into the roof while providing air gaps for air circulation. The water return baffle can be attached to the solar roof tile by clamping or by at least one of the following methods: adhesive, screws, nails, bolts, clips, etc.

[0023] Another aspect of the invention is a solar roof kit for pitched roofs, comprising at least two fixing devices as described above and at least one solar roof tile, wherein the two fixing devices are mounted to and supported by the slats of the pitched roof. Preferably, the solar roof kit includes further necessary sealing elements to provide a watertight roof.

[0024] Another aspect of the invention relates to a solar roof comprising at least one solar roof tile as described above, the solar roof tile being supported by at least two fixing devices mounted on slats as described above. In the case where both (ordinary) roof tiles and solar roof tiles are integrated into the solar roof, the solar roof tiles and (ordinary) roof tiles preferably have similar heights in the longitudinal x-axis, resulting in a more aesthetically pleasing outcome.

[0025] In a preferred variation, the mounting bracket can be configured to fix (ordinary) roof tiles in a first bracket area and solar roof tiles in an adjacent second bracket area, such that the (ordinary) roof tiles are tightly connected to the first bracket area. The first bracket area and the (ordinary) roof tiles are preferably tightly connected by a water-tight seal.

[0026] Another advantage of the aforementioned mounting system and solar roof tiles is that non-solar roof tiles can be replaced by solar roof tiles integrated with the mounting system without requiring any changes to the roof's support structure, particularly the tile arrangement and type. This is especially advantageous when renovating existing roofs.

[0041] Certain embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings, which show some, but not all, of the features. In fact, the embodiments disclosed herein can be embodied in many different forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided to enable the invention to meet applicable legal requirements. Where possible, similar reference numerals will be used to refer to similar components or parts.

Figure 2 A perspective view and partially exploded view of a pitched roof 11 with solar roof tiles 2 and fixing devices 1 are shown. The roof 11 shown includes ordinary roof tiles 23 and solar roof tiles 2. Figure 3 It shows Figure 2 A detailed view of the sloping roof 11, indicated by the box marked with F. Figure 4 Perspective views of roof slats 9 and 10 are shown, as well as second and third variations of the fixing device 1 according to the invention. Figure 5 A perspective view of a pitched roof 11 with adjacent ordinary roof tiles 23 and solar roof tiles 2 is shown. Figure 6 This shows a perspective view of the sloping roof from a horizontal angle. Figure 7 A top view of the sloping roof in a partially assembled state is shown. Figure 8 It shows Figure 7 A cross-sectional view of the sloping roof, represented by section line EE. Figures 9 to 12 The fourth and fifth variations of the fixing device according to the invention are shown.

[0043] like Figures 1 to 4 As shown, the fixing device 1 for fixing the solar roof tiles 2 includes a rectangular beam 3 extending longitudinally x. The rectangular beam 3 includes a first support 4, which, in its installation position, supports a first upper slat 9 of the sloping roof 11. Figure 4 For optimal viewing angle, the modified rectangular beam 3 is further supported on the second lower strip 10 by the second support member 5 at the installation position. Figure 4 The installation position of fixing device 1 is shown in the figure, while Figure 3 The center view represents the optimal angle for fixing the solar roof tile 2 to the installation position of the fixing device 1. To fix at least one solar roof tile 2, the fixing device 1 further includes at least one bracket 6 for the solar roof tile 2. Figure 2 and Figure 3 As can be seen from the diagram, in some variations, bracket 6 can fix two horizontally adjacent solar roof tiles 2.

[0044] like Figure 1As shown, in order for the fixing device 1 to prevent water ingress, the drainage channel 7 is positioned adjacent to at least one bracket 6. The drainage channel 7 extends longitudinally x to drain atmospheric water along the longitudinal outer edge 8 of the solar roof tile 2.

[0045] like Figure 1 As shown, the first and second support members 4 and 5 each include at least one first support area 12, which supports the rectangular beam 3 relative to the first upper slat and the second lower slats 9 and 10, which are generally perpendicular to their extension in the longitudinal direction x. In a variation shown, the second support member 5 further includes a second support area 13, which supports the rectangular beam 3 in the longitudinal direction x relative to the first upper slat and the second lower slats 9 and 10.

[0046] The first and / or second support members 4, 5 each include connecting devices, which are provided in their respective first and / or second support areas 12, 13 for secure connection to their respective slats 9, 10. Figure 1 As shown, in this variation, the connecting device includes holes 20 in the respective first and / or respective second support areas 12, 13 for screwing and / or nailing each support 4, 5 to its respective slats 9, 10.

[0047] like Figure 1 As shown, when perpendicular to the approximate extension direction x of the rectangular beam 3, the first support area 12 of the first support member 4 is separated from the bracket 6 by a first distance d1, and the first support area 12 of the second support member 5 is separated from the bracket 6 by a second distance d2, wherein the second distance d2 is greater than the first distance d1. The advantage of this arrangement is that when the solar roof tile 2 is positioned in the installation location, its lower end 15 is inclined relative to the plane defined by the first upper strip and the second lower strips 9 and 10, such as... Figure 4 As shown. In Figure 1 The diagram further shows that the first support area 12 is positioned at a third distance d3 from the upper end 14 of the rectangular beam 3, and the second support area 13 is positioned at a fourth distance d4 from the lower end 15 of the rectangular beam 3, wherein the fourth distance d4 is greater than the third distance d3. A further advantage of this arrangement is that the rectangular beam 3 includes a cantilever portion 16 that extends longitudinally x beyond the second lower slat 10 at the mounting position of the fixing device 1. Figure 2 and 3 As shown, the fixing device 1 with the above structure allows rows of roof tiles, especially solar roof tiles 2, to overlap in the suspended portion 16 of the rectangular beam 3.

[0048] The shown variation of the rectangular beam 3 has a U-shaped cross section in the region of the second support member 5 perpendicular to the longitudinal direction x. Furthermore, the rectangular beam 3 is made of stamped and bent metal sheet.

[0049] like Figure 1 and Figure 4 As shown, the bracket 6 is interconnected with the rectangular beam 3 and forms as a separate component. It is made of an elastic material, more specifically rubber in this case, shaped as a rubber pad. This pad 6 is adhered to the rectangular beam 3. Drainage channels 7 are integrated into the rubber pad; more specifically, multiple drainage channels 7 are integrated into the rubber pad 6. These drainage channels 7 are adjacent to each other, thus providing an intricate seal. The solar roof tiles 2 are positioned at the installation location, which... Figure 3 The most obvious example is in the middle.

[0050] The fixing device includes at least one fastening element 18 for securing the solar roof tile 2 in the installation position along the longitudinal x-axis. In the illustrated variation, the fastening element 18 is shaped as a hook 19 connected to a rectangular beam 3, surrounding the lower horizontal outer edge 22 of the solar roof tile 2 in the installation position, as shown. Figure 3 As shown. In addition, the solar roof tile 2 is fixed by the fixing device 1 and / or the roof tile 23 and / or the suspended part 16 of the solar roof tile 2.

[0051] Ribs 17 extending from the installation location near the drainage channel 7 are positioned between two adjacent solar roof tiles 2. For example... Figure 3 As shown, the ribs are formed as independent components and are connected to the longitudinal outer edge 8 of the solar roof tile 2. Furthermore, the ribs 17 are made of an elastic material to protect the solar roof tile 2 from damage. In the case of two adjacent solar roof tiles 2, each of the two adjacent solar roof tiles 2 is partially mounted on the same bracket 6 of the fixing device 1 disposed between the solar roof tiles 2, which further serves to prevent atmospheric moisture intrusion.

[0052] Another aspect of the invention is a solar roof tile 2 for covering a pitched roof 11 and installed on the slats 9 and 10 of the pitched roof 11 by the aforementioned fixing device 1. Figure 3 The solar roof tiles can be best observed in the middle.

[0053] In a first variation, the solar roof tile 2 includes a strip-shaped sealing element 20 extending parallel to at least one longitudinal outer edge 8 or horizontal outer edge 22 of the solar roof tile 2. A watertight seal can be achieved when the sealing element 20 is positioned adjacent to the horizontal outer edge 22 of the solar roof tile 2 on the sun-facing side in its installation position, within an area shaded by the suspended portion 16 of the adjacent solar roof tile. In the area covered by the strip-shaped sealing element 20 and / or in the area where one side of the solar roof tile 2 is shaded by the suspended portion 16 of the overhead fixing device 1, the solar roof tile 2 does not have solar cells.

[0054] In the second variation, the solar roof tile 2 includes a water return baffle 24 extending parallel to at least one longitudinal outer edge 8 of the solar roof tile 2. At the installation location, the optimal viewing angle is as follows: Figure 8 As shown, the water return baffle 24 provides an air gap 25 in the suspended portion 16 between the solar roof tile 2 and another solar roof tile 2 mounted directly above it. This allows airflow 26 to flow in the suspended portion 16 between the solar roof tiles 2 while minimizing the amount of water that may enter the sloping roof 11. The airflow 26 circulating behind the solar roof tiles 2 transfers heat away from them.

[0055] In this second variation, such as Figure 7 As shown, a water backflow baffle 24 is disposed on a surface adjacent to the horizontal outer edge 22 of the solar roof tile 2. In a variation shown, the water backflow baffle 24 is a rubber strip with a triangular cross-section that connects the solar roof tile to the lower end 15 of the fixing device 1 mounted on it.

[0056] Figure 5 A conventional roof tile 23 is shown, with one of its longitudinal outer edges 8 mounted on a bracket 6 of a fourth variation of the fixing device 1 according to the invention. The bracket 6 and the conventional roof tile 23 are interconnected by an intricate seal in a water-tight manner. The conventional roof tile 23 and the solar roof tile 2 have similar lengths in the longitudinal direction. Adjacent to the conventional roof tile 23, the bracket 6 secures the solar roof tile 2 by means of hooks 19 provided at the lower end 15 of the rectangular beam, preventing slippage in the longitudinal direction x.

[0057] Figure 6A sloping roof 11 is shown, with its solar roof tiles 2 mounted on its slats 9 and 10 by a fixing device 1 according to the invention. It can be seen that the solar roof tiles 2 are secured not only by the hooks 19 of the fixing device 1 but also by the suspended portion 16 of the fixing device 1. A strip-shaped sealing element 21 is provided between the solar roof tiles 2 and the suspended portion 16 above. The sealing element 21 further serves as a spacer between the solar roof tiles 2 and the fixing device 1. It can also be seen that the fixing device 1 provides a support 6 for the solar roof tiles 2, the support being inclined relative to the plane defined by the first upper slat and the second lower slats 9 and 10.

[0058] The above description applies with similar advantages. Figures 9 to 12 The fourth and fifth variations of the fixing device 1 are shown. However, these variations differ in that at least one solar roof tile 2 is attached to the fixing device 1. Here, the fixing device 1 and the solar roof tile 2 preferably form a building block of the pitched roof 11. The connection between the solar roof tile 2 and the fixing device 1 can be accomplished by a mechanical connection device; however, the connection is preferably accomplished by an adhesive. One advantage of using an adhesive is that a watertight seal can be achieved if the adhesive is applied along the support 6 and / or the rectangular beam 3. The fixing device 1 typically includes at least one fastening element 18, and in the fourth variation, the fixing device 1 includes hooks 19 for securing adjacent tiles supported by the support 6 of the fixing device 1 in the installation position.

[0059] like Figure 11 and 12 As shown, a fifth variation of the fixing device 1 typically includes two fastening elements 18, which, in the installed state, are interconnected with associated fastening elements 18' connected to the surface of the solar roof tiles. In this fifth variation, the fastening elements 18 extend vertically from the rectangular beam 3 and are substantially perpendicular to the longitudinal direction x. The associated fastening elements 18' are tightly connected to the fastening elements 18 in a locking manner in the installed state. The associated fastening elements 18' can be formed as a substantially L-shaped receiving notch, and the fastening elements 18 can be substantially rod-shaped for engaging with the notch. The associated fastening elements 18' can be disposed on a substantially L-shaped metal plate connected to the surface of the solar roof tiles 2, particularly in the installed state, to the surface of the solar roof tiles 2 facing the strips 9, 10.

[0060] Furthermore, the text used in this specification is descriptive rather than restrictive, and it is understood that various changes can be made without departing from the spirit and scope of the invention.
