Definitions

• Fastening element for mounting solar modules or solar collectors on a roof and pitched roof with a fastening element
• the invention relates to a fastening element for mounting solar modules or solar collectors on a roof, with a base part which can be mounted on the roof, and a hook part which can be fixed by means of a pivot-latching mechanism on the base part. Furthermore, the invention relates to a pitched roof with such a fastener.
• fasteners in the form of so-called roof hooks are used, which form part of the support structure. These fasteners are hook-shaped so that they can embrace the tiles, and are bolted at one end to the rafters or possibly the roof battens of the house. At the other end they carry a rail construction for the solar modules or solar collectors or the modules / collectors directly themselves.
• a fastener of the type mentioned that the pivot-latch mechanism can be hooked to the base part Includes connecting hook and a snap closure, which are spaced apart in the longitudinal direction of the hook portion.
• the longitudinal direction of the hook part which engages in the assembled state, the roof tile, just the lever arm under load, and the connecting hook defines the axis of rotation. Since, therefore, in the embodiment according to the invention, the latching closure and the connecting hooks are spaced apart from one another, the latching closure can not or not easily be released under load, as is the case with the arrangement known from the prior art. Rather, in the fastener according to the invention by the chosen geometries ensured that weight loads, such as a snow load occurring in winter, act on the snap-lock in the latching direction, whereby the latching connection is particularly stable.
• the hook part is in particular U-shaped, and the position of the snap closure divides the length of the roof facing the leg approximately in the ratio 1: 2 or 1: 1.
• the connecting hook and the latching closure at a distance from each other, which substantially corresponds to a width of the base part.
• the hook portion is formed substantially U-shaped, wherein on a first leg of the pivot-latching mechanism is arranged and on a second leg, the solar module or the solar collector can be set.
• a fastener is easy to produce and is well suited by its shape to surround the roof tiles of the roof.
• connection hook is arranged at the free end of the first leg of the hook part. This facilitates hanging the connection hook on the base part and thus the mounting of the fastener.
• connection hook engages behind a projection on the base part in the suspended state. That's how it is ensures that the connection hook does not become undesirable when the hook part engages.
• the latching closure comprises a web formed on the hook part with a latching nose, which engages behind a projection on the base part in the locked state.
• the connection hook thus results in a secure connection of the base part and hook part.
• the hook part In order to initiate the forces acting on the fastening element and in particular the hook part forces, for example a high snow load in winter, in the base part and thus the roof, the hook part preferably has a stop web, which is arranged between the connecting hook and snap lock. With this, the hook part can be supported in the mounted state on the base part.
• a projecting stop web also has the advantage that the base part can have a comparatively small height, which results in material savings and permits installation with short screws.
• the stop web is arranged in the immediate vicinity of the latching closure, whereby a deformation of the latching closure under load is largely prevented.
• a particularly cost-effective embodiment results from the fact that the base part as a rail, so as a standard component is formed.
• the above-mentioned object is also achieved by a pitched roof with a fastening element, as described above, wherein the connecting hook in the mounted state on the roof is located on the higher side of the base part.
• the connection hook absorbs the forces directed downwards, and the latching closure prevents lifting of the hook part, for example due to wind suction.
• a load acting on the hook part acts on the hook part around the connecting hook in the sense of latching of the latching closure. This facilitates on the one hand the assembly, on the other hand, a release of the hook member is prevented under load.
• FIG. 1 is a perspective view of a fastener according to the invention, wherein the hook part is mounted in the base part;
• FIG. 2 is a perspective view of the fastener of Figure 1, which illustrates the engagement of the hook portion
• - Figure 3 is a perspective view of the fastener in the locked state of the hook part
• FIG. 4 is a schematic side view of a pitched roof according to the invention with the fastener of Figures 1 to 3.
• FIGS 1 to 3 show a fastener 10, with the solar modules as part of a photovoltaic system or solar panels as part of a solar thermal system on a roof, in particular a pitched roof, can be set.
• the fastener 10 has a base portion 12 which is formed as a rail with a plurality of parallel projections and fixed on the roof, in particular screwed to the rafters.
• the fastening element 10 comprises a hook part 14 which is substantially U-shaped.
• a pivot-locking mechanism is provided which comprises a hook-on base member 12 connecting hooks 18 and a snap fastener 20 which are spaced apart in the longitudinal direction L of the hook portion 14.
• the latching closure 20 is located between the connecting hook 18, which is arranged at the free end of the first leg 16 of the hook portion 14, and a center leg 22 of the hook portion 14.
• a subsequent to the center leg 22 second leg 24 of the hook portion 14 serves to set the solar module or the solar collector (not shown).
• the second leg 24 has a slot 26 in which by means of a screw 28, a holder 30 is slidably mounted. The solar module or the solar collector or a rail construction connected thereto can then be clipped onto the holder 30.
• the first leg 16 is slightly angled in the region which lies above the base part 12 in the mounted state and thereby further opened (see also FIG. 4).
• the snap fastener 20 is disposed on the first leg 16 and divides its length approximately in the ratio 1: 2, that is, the part of the first leg 16 which projects beyond the base part 12 is approximately twice as long as the part which extends over the base part 12 is located.
• the second leg 24 ends approximately at the height of the latching closure 20 on the first leg 16.
• FIG. 1 now shows a first step for connecting the hook part 14 to the base part 12, in which the connection hook 18 is suspended in the base part 12 such that the connection hook 18 has a projection 32 on the base part 12, more precisely at a first end of the base part 12. engages behind (see arrow P ⁇ . In this case, the connecting hooks 18 in the suspended state upwards, so when mounted on the roof in approximately skyward.
• the hook part 14 is locked by a pivoting movement, indicated by the arrow P 2 in Figure 2, in the base part 12, wherein an integrally formed on the hook part 14 web 34 with an end attached thereto locking lug 36th a projection 38 on the base part 12 engages behind.
• the projection 38 is disposed on the opposite with respect to the connecting hook 18 end of the base part 12.
• the web 34 with the latching nose 36 forms the latching closure 20, which defines the hook part 14 on the base part 12 in combination with the projection 38.
• the hook part 14 also has a stop web 40, which is arranged between the connecting hook 18 and the snap fastener 20 in the immediate vicinity of the snap fastener 20.
