Fastening device for pivoting roof elements

The invention relates to a fastening device, in particular for the pivotable fastening of roof elements that can be opened, consisting of a first fastening element, which is assigned to the roof elements, and a second fastening element, which is assigned to a supporting roof structure, wherein the fastening elements each have a molded-on eyelet and the congruent eyelets are connected to one another by a coaxially inserted connecting element.

Fastening devices of the generic type are known and are preferably used with immovable aluminum profiles for cladding or coverings over corners or other projections, as well as with roof structures to connect two profiles together. One of the profiles usually has a molded round thickening in the longitudinal direction as the first fastening element and the other profile is equipped with a corresponding groove as the second fastening element. The thickening is pushed into the groove during assembly or, if necessary, clamped in so that a positive connection is created. The disadvantage is that the mobility of the profiles relative to one another is limited by the molded fastening elements, so that a large number of individual profiles must be kept on hand in order to enable a clean finish for all conceivable cases and angle combinations. The variety of profiles and their production causes additional costs. The assembly and disassembly of such profiles is also very difficult because the two fastening elements must be joined together beforehand and only then can they be screwed to the other construction elements. Disassembling a single profile with fastening elements is therefore easy.

2/24

no longer possible because the two connected profiles usually have to be removed. Furthermore, prefabrication of the construction elements in the factory is almost impossible. If the two profiles are later joined together, large, heavy construction elements may have to be moved against each other, which are very difficult to handle when bringing together the known fastening elements and increase the overall workload on site and thus make assembly more expensive. If roof elements are also involved, great care must be taken during assembly due to the risk of falling.

Furthermore, fastening devices are known which consist of individual profiles, each of which has an eyelet formed on it, and a connection between the various fastening profiles is made by an inserted connecting element. The eyelets are arranged so that they coincide for assembly and the connecting element is inserted into the existing eyelet in such a way that it passes through the eyelets of both the one and the other fastening element. For example, a fastening device for a curved roof skylight is known from DE-US 35 33 144, in which a lower profile is angled or rounded and is equipped with a correspondingly shaped eyelet. The curved roof element is also assigned an end profile which at least partially surrounds the edge of the roof element and also has an integrally formed eyelet. A short connecting element is inserted into the front surface of the open eyelets, which passes through at least one eyelet of the lower or upper end profile. The disadvantage of this type of fastening device is that, on the one hand, due to the small dimensions of the existing eyelets and the surface loads caused by the roof element, there is no sufficient

3/24

Stability is guaranteed. Furthermore, a cold bridge is formed via the external end profiles and the fastening device via the connecting element.

Therefore, the known fastening method is particularly disadvantageous when using double-shell profiles that enable thermal separation of the lower and upper rungs, because the molded fastening elements create a thermal bridge between the upper rung of the roof structure and the lower rung of the roof element, which leads to a not insignificant heat loss in heated buildings. The selected design is also only intended for fixed roof skylights and therefore does not take into account the required angular mobility of the profiles relative to one another.

The invention is therefore based on the object of creating a pivoting fastening device which can be subjected to high loads and enables a permanent and quickly detachable fastening and, in addition, improved thermal insulation.

According to the invention, in order to achieve the object, the fastening element assigned to the roof element extends continuously over the entire width or length of the roof element and is connected to it and that the fastening element is provided for receiving at least one connecting element, wherein the at least one connecting element protrudes at least on one side over the width or length of the roof element and engages in the eyelet of the fastening element assigned to the roof structure.

4/24

By designing the associated fastening element over the entire width or length of the roof element, a stable fastening is created on the one hand, which can withstand even greater wind loads when open and closed, and on the other hand enables a thermal separation between the lower and upper rungs. In addition, the fastening element provides further stiffening of the movable roof element. The connecting element to be used can, for example, also be designed over the entire width or length of the roof element and thus contribute to the stability and at the same time engage with the corresponding fastening elements of the roof structure, so that a simple but effective and particularly advantageous fastening option with few individual parts is created. The design according to the invention also eliminates the disadvantages known from the prior art. The construction elements can be provided with the fastening elements to be held during pre-assembly at the factory, while during assembly on site only the connecting element needs to be inserted, so that the amount of work on the construction site is significantly reduced. Dismantling is possible at any time by simply pushing out the connecting elements, without having to loosen the other construction elements. Another advantage is that the fastening elements can be arranged in a space-saving manner and can be generously dimensioned, so that the fastening elements can absorb significantly higher loads. In addition, the fastening elements can be screwed directly to the lower and upper rungs of the double-shell profiles in order to ensure a sufficiently stable connection. The fastening elements can also be arranged concealed by the profiles in order to achieve a uniform overall impression of the cladding or roof elements and

5/24

if necessary, to prevent the ingress of moisture and heat loss. A significant advantage is that thermal insulation can be provided between the individual fastening elements and the profiles of the roof structure or the corresponding roof elements in order to prevent heat transfer between the double-shell profiles.

The assembly of the movable roof elements is extremely simple and can be carried out with little effort thanks to the generous dimensioning of the fastening device.

In a particularly advantageous embodiment of the invention, it is provided that only a single connecting element is provided that runs across the width or length of each movable roof element, so that a particularly high level of stability is achieved and storage is reduced by using fewer identical components and the greater clarity means that assembly can be carried out much more quickly.

In a special embodiment of the invention, it is provided that the at least one connecting element is designed to protrude over both sides of the roof element and engages on both sides in the eyelets of the fastening elements assigned to the roof structure. This type of assembly is preferably used for individual movable roof elements, whereby the lateral fastening elements of the roof structure can be adapted to the loads occurring according to the size of the movable roof element.

Alternatively, in a further advantageous embodiment of the invention, it is provided that several movable roof elements

6/24

are arranged next to each other and the associated connecting elements engage coaxially in the fastening elements of the adjacent roof elements and/or the roof structure at least over a partial area. This type of assembly allows several roof elements lying next to each other to be fastened, whereby the connecting elements are used alternately to hold two roof elements and the end faces of the connecting elements lying next to each other are arranged centrally in the fastening element of the roof elements or the roof structure.

To secure a single roof element, fastening elements of the roof structure are arranged on both sides of the movable roof element.

In a further cost-effective embodiment of the invention, it is provided that the connecting element consists of a sleeve or a pipe section or a round rod and that the fastening elements consist of a flat profile with a straight leg and a curved, integrally formed or welded eyelet, wherein the legs are intended for fastening to the roof elements or the roof structure. The main advantage of this design compared to the prior art has already been mentioned and consists in the fact that the fastening elements are not integrally connected to the profiles, so that a thermal separation can be made between the fastening elements and the profiles. The thermal separation can, for example, consist of a corresponding heat-insulating intermediate layer between the screwed-on legs of the fastening elements and the profiles or

7/24

if necessary, a heat-insulating coating on the fastening elements.

In order to ensure sufficient stability of the fastening elements, it is furthermore intended that the eyelet has an outer diameter that corresponds to half or the full length of the outgoing leg.

In order to enable a clamping connection between individual profiles and the fastening elements, it is intended that the outgoing leg is bevelled laterally or in thickness towards the free end, so that a self-retaining clamping connection can be made with a corresponding bracket in the profiles. In order to keep the fastening arrangement as small as possible with maximum stability, it is also intended that the outgoing legs are aligned to one side.

In a particularly advantageous embodiment of the invention, it is provided that the tapered legs of the fastening elements have a stepwise or continuously adjustable opening angle of 0 to 180 degrees relative to one another and thus the movable roof elements to the roof structure, whereby the selected design of the fastening elements ensures sufficient stability even when the roof elements are open with an opening angle of 180 degrees.

In a further embodiment of the invention, it is provided that the first and second fastening elements are welded, screwed or otherwise connected to the roof structure or the movable roof elements, whereby the fastening elements are thermally separated from the roof structure and/or the roof elements.

8/24

In order to improve the thermal separation of the roof element, it is intended that the fastening elements are covered by the heat-insulating light element, whereby the connecting element, which ensures the connection between them by simply inserting it into the eyelet, is also located on the outside and is thus thermally separated from the interior.

In order to prevent moisture from penetrating the opening in the roof structure in the area of the movable roof elements, the side upper rungs of the opening are covered by the heat-insulating light element and the light elements are provided with a closing profile and a lip seal on the edges.

To avoid heat loss due to heat radiation via the fastening elements in the open eyelet area, it is further provided that the eyelet area open to the outside is covered by thermal insulation, which can consist, for example, of an insulating intermediate plate or a glued-on foam profile and that an insulating tube is pushed onto the connecting element between the fastening elements, which has an outer diameter corresponding to the outer diameter of the eyelets. The additional insulating tube provides additional thermal insulation of the connecting element, so that a higher insulation value, which is close to that of the inserted light elements, is also achieved for the fastening device, while at the same time sealing against the framed light elements is achieved.

In a further embodiment of the invention, it is provided that the fastening elements and the connecting element are made of aluminum.

9/24

According to a further feature of the invention, it is provided that the movable roof elements can be curved and that there is a maximum opening angle of 180 degrees, whereby the movable roof elements can be opened using a pneumatic or electric motor horn device and are additionally held in the closed state by a locking mechanism. The invention is further characterized by the use of thermally insulated aluminum profiles and fixed or movably arranged flat or curved roof elements, in particular light strips, ventilation flaps, covers or the like, while maintaining the thermal separation.

The invention is explained in more detail below with reference to the figures. - It shows

Figure 1 shows a perspective external view of a fastening device 100 for an opening roof element 101, which can have an opening angle of 0 to 180 degrees. In the embodiment shown, the fastening device 100 is connected, for example screwed or welded, to an upper rung 102, which forms part of a light strip, and to the roof element 101 on the one hand. Instead of being connected to the upper rung 102, the fastening device 100 can also be connected directly to the roof structure.

The roof element 101 is made up of several aluminum profiles, which consist of lower rungs 103 joined together at right angles and upper rungs 102 (not shown) as well as other end profiles. In Figure 1, only the lower rung 103 is shown in a clear representation, while the upper rungs 102 can also be seen in Figure 2. For example, a light element 104, which consists of an extruded chamber profile, rests on the lower rung 103. In Figure 1, the roof element 101 is also shown without side borders for better representation. The light element 104 is attached between the upper and lower rungs 103, which enclose the side edges 105 of the light element 104 and can be screwed or clamped together. The lower rung 103 with the groove 106 is provided in the example shown for clamping the upper rung 102 using a clamping body. A U-profile! 107 forms the end of the laterally protruding edges of the

11/24

Light element 104 and prevents moisture from penetrating the multi-chamber profile. Instead of the light element 104, another cover or an opaque element could optionally be provided and held over the profiles.

The fastening device 100 further comprises a first fastening element 108, which is connected to the lower rung 103, and a second fastening element 109, which extends over the width or length of the roof element 101 and is screwed or welded to the parallel lower rung 103. The two fastening elements 108, 109 are furthermore constructed identically and consist of a flat profile with a straight leg 110 and an integrally formed eyelet 111, the fastening elements being arranged next to one another with congruent eyelets 111 and legs 108 pointing in one direction in such a way that a connecting element 112 is mounted coaxially in the eyelets 111. The fastening elements 108, 109 together with the connecting element 112, which consists of a pipe section or a round material, form a kind of hinge, whereby the selected cross-section of the eyelet 111 and the connecting element 108, 109 ensures a high load with sufficient stability in the closed and opened state. The main difference between the two fastening elements is that the fastening element 109 extends over the entire width or length of the roof element 101, while the other fastening element 108 is adapted to the width of the lower rung 103. In a single roof element 101, the connecting element 112 protrudes laterally from the fastening elements 109 and engages coaxially in the lateral fastening elements 108, which are assigned to the roof structure. The particular advantage of the invention is that the tapered legs 110 of the

12/24

Fastening elements 108,109 to each other and thus the roof element 101 to the roof structure enable a stepwise or continuously adjustable opening angle of 0 to 180 degrees. This type of fastening device 100 also enables particularly large-area roof elements 100 to be held in both the closed and the open state. The fastening device 100 is particularly intended for use with roof elements 101 that can be opened and are equipped with an electric motor or pneumatic drive and thus enable fully automatic opening and closing, whereby stability is ensured in every opening position and the entire arrangement has a high level of wind stability and torsional rigidity. The stability of the fastening device 100 is achieved in particular by the large-scale design of the fastening elements 108, 109 and by the coaxially inserted connecting element 112, which is generally also guided over the entire length or width of the roof element 101 and is thus used to increase stability.

Another significant advantage is that a thermal separation is made between the lower rung 103 and the upper rung (not shown). The lower rungs 103 of the roof structure are separated from the rest of the structure by a commercially available roofing welding sheet, for example, for thermal separation, and the connection between the upper rung and lower rung 103 is made, as already explained, by a plastic clamping element. The roof element 101 is made from the same lower rungs 103 and upper rungs 102, whereby the clamping bodies are also used. The fastening element 108 is then only connected to the upper rung 102 and thus has no thermal contact with the lower rung 103 of the roof structure. The fastening element 109,

13/24

which is assigned to the roof element 101 to be opened, is screwed to the lower parallel lower rung 103, with insulation being arranged between the lower rung 103 and the leg 110, or a connection between the leg 110 and the parallel lower rung 103 is made by means of short weld seams. In the case of a welded connection, on the one hand, the thermal separation can be maintained by means of additional insulation, and on the other hand, the thermal bridges in the form of the weld seam can be neglected. The leg 111 of the fastening device 109 is generally connected directly to the parallel lower rung 103, with the underside of the leg 110 preventing a direct thermal connection with the lower rungs of the roof structure by means of a foam tape or another type of insulation.

Figure 2 shows a perspective view of a light strip 113, which is attached to a frame 114 of the roof structure of the roof (not shown). The light strip 113 consists of individual light elements 104, which are mostly fixed and partly lie in the curved area of the light strip or are used as a gable element 115. Furthermore, the light strip 113 is equipped with an openable roof element 101, which is also equipped with a light element 104. The light elements 104 are each held by a lower rung 103 and an upper rung 102 connected via a clamping body. The roof element 101 is connected by a fastening device 100, as can be seen from Figure 1, usually to the roof structure or, as in the embodiment shown, to the light strip 113. The connection is made in such a way that the outer fastening elements 108 are welded or screwed to the upper rung 103 of the light strip 113, while the fastening element 109

14/24

is screwed or welded to the parallel lower rung 103 of the roof element 101 to be opened. The two fastening elements 108, 109 each have an eyelet 111 through which the connecting element 112 extends and enables a hinge-like connection between the two fastening elements 108, 109.

Figure 3 shows the light strip 113 in a sectional side view with the partially opened roof element 101.

Figure 4 shows a top view of the light strip 113 with a fixed and a pivoting roof element 101.

Figure 5 shows a partial section along the connecting line l-l through the roof construction or the light strip 113, the roof element 101 and the fastening device 100, which connects the roof element 101 to the light strip 113. The roof element 101, like the light strip 113, is made up of the lower rungs 103 and the upper rungs 102 with thermal separation. The connection between the two rungs is made via a clamping body (not shown), with the light element 104 being arranged between the lower rung 103 and the upper rung 102. The opening 116 is formed by four lower rungs 103 or upper rungs 102 arranged at right angles to one another, with the lower rungs 103 of the roof element 101 being set back from them and thus being able to protrude into the opening 116.

The roof element 101 is connected to the light strip 113 via the fastening device 100, whereby the leg 110 of the fastening element 108 is connected to the upper rung 102 of the light strip 113.

15/24

is screwed, while the leg 110 of the second fastening element 109 is connected by a weld seam 117 to the lower rung 103 running parallel to the fastening device 100. Both fastening elements 108, 109 have an eyelet 111 in which the connecting element 112 lies coaxially. The upper rungs 102 are additionally sealed against the light element 104 by individual lip seals 118.

Figure 6 shows a partial section along the connecting line H-II through the lateral overlap of the roof element 101 opposite the light strip 113. The light element 104 protrudes laterally over the lower rung 103 and upper rung 102 of the pivoting roof element 101 and has a U-shaped end profile 119 on the outer edge 105, which is further equipped with a lip seal 120 that rests on the fixed light element 104 and thus prevents the penetration of moisture into the opening 116.

Figure 7 shows a partial section along the connecting line III-III of the side of the roof element 101 lying parallel opposite the fastening device 100. Just as on the sides, the pivoting roof element 101 projects beyond the opening 116 of the light strip 113. The protruding part of the light element 104 is in turn closed with an end profile 119 in which there is a lip seal 120 which, when the roof element 101 is closed, rests on the fixed light elements 104 of the light strip 113 and thus prevents the ingress of moisture.
