Roof tile with bracket for solar modules or similar

The invention relates to a holder for the detachable fastening of an object, in particular a solar module,
on a roof covering element, such as roof tiles,
with which the position of the object being recorded is compared
the roof covering element can be adjusted and fixed, wherein the bracket has at least one
Roof covering element has a support element protruding,
which is connected to an adjustable mounting head with which the object is to be held.

The roof covering element is a single or a
A roof tile is a roof tile that is several times larger and is equipped with holding elements to hold the object and can be used instead of a standard roof tile. These are mainly roof tiles made of plastic.

DE 42 27 929 A1 discloses a bracket for solar modules that consists of a set of mounting bolts, double angles and screw elements. The double angles are supported by the mounting bolts that are screwed onto a roof covering element. This bracket is generally suitable for roof covering elements that are several times larger than commercially available roof tiles, in particular so-called Frankfurt roof tiles. The roof covering element has a flat mounting area for screwing on mounting bolts. The angle of inclination of the solar module can only be adjusted by inserting mounting bolts of different heights. A later adjustment of the angle of inclination requires the replacement of mounting bolts. Apart from the fact that the bracket is essentially only suitable for flat roof covering elements, the system appears to be labor-intensive, with the adjustment options being limited by the mounting bolts available.

The object of the invention is to design a new type of holder of the type mentioned at the beginning, which is suitable for a wide variety of roof tile types, including those with a strong profile. A further object of the invention is to simplify the adjustment of the angle of inclination.

This object is achieved by a holder of the type described in the preamble in that at least one holding element is firmly connected to the roof covering element, to which the support element or part thereof is detachably attached,

&ugr;·.

and that the support element is height adjustable.

Preferably, the holding element is designed in the form of a receiving shoe incorporated into the roof covering element, into which a base element of the holder opposite the receiving head can be pushed.

Furthermore, the inventive concept also relates to a roof covering element, such as a roof tile, which has at least one holding element compatible with the base element, such as a receiving shoe.

Preferably, the receiving shoe is provided with at least one hole, for example a threaded hole, into which a locking element, such as a locking screw, can be inserted. This allows the element of the holder inserted into the receiving shoe to be securely fixed.

Preferably, the holding element, in this case the receiving shoe, is made in one piece with the roof covering element. However, it is not impossible to firmly connect a separately manufactured receiving pocket or shoe, or a part of the holder of another type, such as a pipe socket, to the roof tile, for example by screwing or gluing it, whereby care must be taken not to impair the watertightness of the roof tile. However, it is possible to provide the receiving shoe with a water drainage opening.

In a simplest embodiment, the retaining element integrated with the roof tile can be designed as at least one element that protrudes beyond the surface of the roof tile and

There should be a flat strip section made in one piece with the roof tile, which is provided with at least one opening for inserting a screw or another fixing element. The openings should be arranged so that they coincide with corresponding openings in the rest of the bracket or the support element or part thereof. Instead of a rectangular flat strip section, there can be a rounded flat structure, e.g. similar to a partial circle. A simple solution can also be a pipe socket or the like attached directly to the roof tile or made in one piece with it.

The support element is preferably designed in the form of a joint mechanism, all of whose joint members can be rotated in a single plane. The joint mechanism can be a parallelogram, i.e. a four-bar linkage, with one pivot point on the holding element or base element and the second pivot point, opposite the first, on the receiving head. The joint mechanism can also be Z-, X-, V- or Y-shaped. The use of the joint mechanism alone enables the receiving head to be adjusted in only one plane, which is perpendicular to the roof skin or slightly inclined when installed.

The support element and/or the receiving head can also be pivoted about a rotation axis that is arranged vertically or at an angle to the roof covering element. This pivoting ability refers to several planes that are arranged parallel or at an angle to the roof tile or roof covering.

The recording head can be pivoted in various ways. For example, the well-known joint head tripod principle can be used.

In the case of an articulated, V- or Y-shaped support element, the receiving head or the support element can have a guide in which a first free end of the support element facing the receiving head or, accordingly, a pin or screw firmly connected to the receiving head can be guided, with a second free end of the support element, also facing the receiving head, being articulated to the receiving head. The angular position of the receiving head can be fixed by detachable screw connections at the first and second ends of the support element, as well as at other pivot points of the articulated support element.

The support element can have at least one telescopic or threaded tube that is placed on a pipe socket of the base element or attached directly to the base element or roof tile. The support head can be connected to a free end of the tube via a simple, flat swivel joint. This allows both the height adjustment and the pivoting ability of the support head and thus the solar module in all directions.

If the holding element of the roof tile is designed as a flat receiving shoe, a plate-shaped base element compatible with the receiving shoe can be used, which is either rectangular, oval or circular when viewed from above on its flat side.

• · ♦_#

The base element can be profiled while maintaining its compatibility with the receiving shoe.

It is also possible to use a curved base element, which can also be inserted into a suitably adapted receiving shoe and rests with its base on the lower part of the receiving shoe or on the roof tile. This option can be used, for example, if a support element is provided that can be pivoted about an axis that is perpendicular or inclined to the roof tile, so that the receiving head can be rotated about this axis. In such a case, a free space can be created below the inserted base element in which a locking element, such as a threaded nut, is located and which is easily accessible for the fitter.

Finally, it is conceivable to use a detachable locking or snap connection between the base element and the receiving shoe.

In this way, the bracket according to the invention can be adjusted in an X-Y-Z coordinate system, i.e. in all desired directions, without having to use additional elements such as exchangeable spacer bolts, whereby the adjustment options, in relation to the angle of sunlight, are practically unlimited. The bracket can be mounted on pitched and flat roofs.

It should be noted that the holder according to the invention can be used not only for solar modules, but also for other primarily flat objects, for example for advertising boards.

Figures 16 to 19 show a base element with a spring-loaded tab.

In Fig. 1, an ensemble 30 is shown, consisting of a support element 5 with a receiving head 6 and a roof covering element 1. The roof covering element 1 is a roof tile formed from plastic, which has a holding element 7 in the form of a flattened receiving shoe.

In the present case, the support element 5 is a four-bar linkage which is connected to a plate-shaped, rectangular base element 4 via a hinge point 26 and to the receiving head 6 via a second hinge point 27 opposite the hinge point 26.

According to Figures 2 and 3, the base element is inserted into the receiving shoe 3, which is made in one piece with the roof tile.

4 is pushed in along the arrow 14 and fixed there by means of a screw-like locking element 8. The receiving head 6, the support element 5 with the base element 4 and the receiving shoe 3 of the roof tile thus form a holder 100. The receiving shoe itself has a cuboid-shaped compartment 38 into which the base element 4 can be pushed.

In the present case, the receiving head 6 is manufactured as a two-part flat bar 9 with U-shaped holding elements 16.1, 16.2 arranged at the end, with which the respective object, such as a solar module 20 shown in Fig. 7, can be held. An elongated hole 17 made in the flat bar enables the setting of a distance A between the U-shaped holding elements 16.1, 16.2 depending on the size of the solar module.

As can be seen from Figures 1 to 4 and 7, the object, in this case the solar module, can be raised, lowered and pivoted relative to the roof tile 1. However, pivoting is only possible in a single plane E (see Figure 7), which runs perpendicular to the roof tile. Figures 2 and 4 show an oblique and correspondingly a parallel position of the receiving head relative to the roof tile.

If a round base element 4 is used as shown in Fig. 9, it is possible to rotate with the support element 5 and thus with the receiving head 6. The desired position can be determined with the locking element 8 inserted into a slot 34 or bore 35 (see Figures 1 to 3). Both the rectangular base element 4

t ·

according to Fig. 8, as well as the round base element 4 according to Fig. 9 carry a tab 2 with an opening for the articulated connection with the support element.

According to Fig. 10, two semicircular tabs 29 with coincident openings 36 are arranged at a slight distance from one another on the rectangular base element 4 for the articulated connection to a lowermost articulated arm 33 of the support element. Peripheral openings 37 for fixing the articulated arm 33 can also be arranged on the tabs 29.

Fig. 11 shows an approximately trough-shaped base element 4, the central web 39 of which has a centrally arranged opening 40 for receiving and fixing a pipe socket (not shown) on which the other elements of the holder can be supported. The base element can also be U-shaped. The compartment 38 of the receiving shoe is enlarged accordingly.

Another articulated embodiment (reference number 15) of the support element is shown in Figures 5 and 6. This also involves adjustability in one plane. The articulated support element 15 is Y-shaped, i.e. it has a central articulation point 28 which connects three articulated arms 31, 32 and 33 to one another, whereby the arms 31 and 32, forming a V-shaped configuration, carry the receiving head 6. The third arm 33 is articulated to the base element 4. The receiving head 6 according to Figure 5 is shown as being in two parts, but can be made in one part. A guide 19 is attached to the receiving head 6, in which a threaded bolt with nut,

·

·

which is arranged at the free end 22 of the articulated arm 31, can be guided during manipulation with the setting angle and can be fixed there. The second articulated arm 32, on the other hand, is connected to the receiving head 6 in an articulated manner at its free end 23. The final position of the receiving head 6 is determined by tightening the screws located at the articulation points of the support element and in the guide 19.

Fig. 13 shows a holder 200 with a Z-shaped, articulated support element 25, which is connected to the receiving head 6 and to the base element 4 via a hinge point.

In Fig. 14, a holder 300 is shown which is characterized by an X-shaped configuration of an articulated support element 45. The support element 45 is composed of two intersecting articulated arms 41, 42, one of which is in two parts and has an elongated hole 43. Furthermore, a guide 19 as already mentioned is arranged on the receiving head 6 and on the base element 4, with at least one of the two articulated arms 41, 43 being provided with an elongated hole 43. The adjustment of the angular position of the receiving head 6 is similar to that in Figures 5 and 6.

In Fig. 12, a bracket 400 is shown with a pipe socket 13 with an external thread arranged on the base element 4 (or directly on the roof tile). A pipe section 4 4 is screwed onto the pipe socket 13, the flattened, free end of which has a flat swivel joint 46. After setting a corresponding angle

• · «I

the mounting head is fixed opposite the pipe section 12 at 4 6. From the figure it can be seen that the holder can be pivoted about an axis X (pipe axis) and fixed with a locking screw 53. 5

Fig. 15 shows a schematic view of another holder with a scissor-like support element 5 according to Fig. 1. The support element 5 is connected to a rotary plate 18.1, which has several peripherally arranged holes 29. Below the rotary plate 18.1 there is another rotary plate 18.2 with holes, which in turn is inserted into the receiving shoe 3 via a plate-shaped base element. The two rotary plates 18.1, 18.2 are arranged coaxially to one another and thus adjustable relative to one another. The lower rotary plate can be dispensed with if corresponding holes are provided on the base element that correspond to the peripheral holes 29 of the rotary plate. The receiving shoe itself is arranged on a square, flat plate 47 made of plastic, which is connected to a roof covering (e.g. roofing felt) of a flat roof via four screw holes 48. An oval or round plate 47 can be used instead of a polygonal plate. The support element 5 with the upper turntable 18.1 can be pivoted about the axis X.

Finally, Figures 16 to 19 show a flat base element 4 with a springy tab 51, which is created by making a straight cut 50 in the material of the base element. Due to the heat effect, the tab 51 is bent by a small amount D of a few millimeters (see Fig. 16), so that when inserted into the receiving shoe 3, it is pressed together.

·

·

·

In this position, the base element remains tense and presses against an inner surface 52 inside the receiving shoe. If the base element is to be pushed out of the receiving shoe 3, it is sufficient to press against the tab 51 via an existing opening on the base element, as shown in Fig. 19. This can be done with a simple tool, such as a screwdriver. The opening can be closed with a removable plug (not shown).
