Description

Frame construction with corner connector

The invention relates to a frame for a lamellar roof with a frame with two spaced apart transverse bars and two the crossbars at the ends connecting longitudinal beams, with at least one post, which carries the frame at least one connection point between a cross bars and a longitudinal beams, wherein the transverse bars and the longitudinal beams are formed as hollow profiles, and wherein the transverse spars a Querholmeninnenwand and spaced therefrom arranged cross-member outer wall and the longitudinal beams has a longitudinal spar inner wall and a spaced therefrom disposed longitudinal spar outer wall.

From DE 10 2013 109 391 A1 discloses a slatted roof with slats is known. The rotatable about their longitudinal extent by means of an adjusting device slats are held in a frame profile. The frame profile is mounted on a wall or on support posts. The slats can be rotated about a rotation axis between a closed and an open rotational position. In their closed position, the lamellas overlap, so that a closed roof surface is formed. In its open position is the roof surface between the slats, allowing sunlight to enter the space below. The fins are designed to accommodate solar cells or solar panels for converting solar energy into electrical or thermal energy.

The provided with photovoltaic modules slats and the associated adjusting device together, even with a design of the slats in lightweight construction, a considerable weight. The frame profile and the support posts must therefore be made sufficiently stable to carry the weight and to be able to absorb the forces occurring during the adjustment of the slats can. The appearance of a light roof suitable for terraces, for example, should not be lost. The frame profile and the support posts must be easily and quickly adaptable to different installation situations, for example to a non-level ground or to different roof sizes. Likewise, a simple and quick installation of the lamellar roof on site with a few installers must be possible.

It is therefore an object of the invention to provide a frame for a slatted roof with slats, which support photovoltaic modules, which has a high mechanical stability, is easily adaptable to different installation situations and allows easy and quick installation of the slats roof on site.

The object of the invention is achieved in that at least one longitudinal members and a cross members are connected to each other by means of a corner connector, that the corner connector has a longitudinal leg and a transverse leg arranged at an angle, that the longitudinal leg in a first hollow chamber of the longitudinal spar and the transverse leg in a second hollow chamber of the transverse spars is inserted and respectively connected thereto and that the corner connector is fastened to the post with at least one fastening means. Through the corner connector, the cross beams and the longitudinal beams can be easily and quickly connected to each other. The corner connector stabilizes the corner area of the frame. The attachment of the frame to the post is done also on the corner connector. This can be made solid, so that a mechanically strong load connection between the frame and the post can be made. It is not necessary to connect the transverse and longitudinal beams directly to the posts and to transfer the forces occurring due to the weight of the lamellar roof and possible snow cover to the posts so that the transverse and longitudinal beams can be made comparatively thin-walled and thus light. This is especially advantageous for the lamella roof according to the invention with photovoltaic modules, since the lamellar roof has a high weight compared to lamellar roofs without photovoltaic modules as a result of the photovoltaic modules. By introduced into the hollow chamber of the longitudinal and transverse spars longitudinal and transverse legs of the corner connector exact alignment of the longitudinal and transverse bars is achieved to each other. Their angle to each other is exactly predetermined by the angle of the corner connector. Preferably, the corner connector at an angle of 90 °. This makes it easy to produce rectangular frames for rectangular louvered roofs. However, any other angles can be realized. By a precise adjustment of the transverse leg and the longitudinal leg of the corner connector to the hollow chamber of the transverse bars and the longitudinal bars a backlash-free or at least low-play storage of the transverse leg and the longitudinal leg can be achieved.

Preferably, the slat roof and thus the frame on a rectangular outer contour. In each of the four corners of the frame, a corresponding corner connector is then arranged. In each of the four corners, a post may be provided to which the associated corner connector is connected. It is obtained as a freestanding lamellar roof. It is also possible that the frame, for example, along one side, on a wall, for example on a building wall, is attached. The attachment of the frame to the wall is preferably by means of fastening means which engage the wall facing the corner connectors. As a result, the corner connectors also allow safe and reliable installation of the lamellar roof on a wall, in particular on a house wall. A secure and mechanically strong connection of the corner connector with a post can be achieved in that the corner connector in its formed between the longitudinal leg and the transverse leg corner holes, in particular stepped holes has. In the stepped holes mounting screws can be fixed axially and bolted to the post.

An exact alignment of the frame relative to the post can be achieved in that the holes, in particular stepped holes, are aligned in the corner region of the corner connector along the bisecting line between the longitudinal leg and the transverse leg. The corner connector is thus pulled when tightening the mounting screws with its outer edge against a preferably designed as Innenkannte area of the post, wherein it centers itself.

For this purpose, it can preferably be provided that the post has at least two inner legs connected at an angle and that the post has two outer legs arranged opposite to the inner legs. The corner connector can thus be mounted in the angular area between the inner legs. The inner and outer legs lead to a high mechanical stability of the post.

A simple and safe installation of the corner connector and thus the frame of the slat roof to the post can be made possible by the post in the corner region between the inner legs threaded blind holes, which are aligned with the holes, especially stepped holes, the corner connector. The mounting screws can be plugged into the stepped holes of the corner connector and screwed into the threaded blind holes of the post. Through the stepped holes, the screw heads of the mounting screws are sunk. The screw heads are axially fixed at the steps of the stepped holes. By arranging the threaded blind holes and the stepped holes in the direction of the bisector formed by the longitudinal and transverse legs of the corner connector of the Corner connector pulled with the mounted longitudinal and transverse bars in the corner area formed by the inner legs of the post and thus aligned exactly and self-centering. When looking from the outside to the lamellar roof, the screw connections between the corner connector and the post are not visible, giving the impression of a screw-free construction.

In order to obtain a sufficient material thickness of the item in its corner region for introducing the threaded blind holes, it can be provided that in the corner region between the inner legs and / or between the outer legs of the post, a corner reinforcement is arranged, through which the threaded blind holes are performed , In this way, a sufficiently long threaded connection can be provided to allow a mechanically strong load connection between the corner connector and the post.

An immediate transition from the transverse struts to the longitudinal struts can be achieved by cutting the longitudinal struts and the transverse struts in their connecting area miter and that corner openings are arranged in the connecting area, which are aligned with the holes, in particular stepped holes, of the corner connector. The cross beams and the longitudinal beams can thus abut each other along their entire cross-sectional circumference. Access to the stepped holes of the corner connector is made possible by the corner openings. Through these corner openings, the mounting screws can be inserted into the stepped bore and screwed into the threaded blind bore of the post. It is formed as a consistently bordered by cross beams and longitudinal beams frame that can be screwed to the pre-assembled or post.

It is envisaged that the cross-section of the hollow chambers increases in stages on their side facing the mounted frame upwards sides, whereby on the longitudinal beams a longitudinal spar-supporting edge and on the cross beams a cross-beam support edge is formed, and that the longitudinal beams with its longitudinal spar-supporting edge on an inner leg and the crossbars with its cross-beam support edge on the adjacent inner leg of the post rests, the weight of the frame with the fins mounted thereon is at least partially transmitted over the support edges on the top of the post. The arranged between the corner connector and the post screw are relieved.

A secure connection of the longitudinal spars to and the transverse spars with the corner connector can be achieved in that threaded holes are introduced into the longitudinal leg of the corner connector, which are aligned with introduced into the longitudinal spar inner longitudinal wall mounting holes and that in the transverse leg of the corner threaded holes are introduced, which with aligned in the cross member inner wall crossbar mounting holes are aligned and / or that the longitudinal beams and the cross bars are connected by screws with the corner connector. Advantageously, the mounting holes are attached to the inner walls of the cross member and the longitudinal spar. The screw connections produced between the transverse bars or the longitudinal members and the corner connector are thus not visible in a view from the outside on the slat roof. It creates the impression of a screwless construction

An easily openable and closable lamellar roof, which converts solar energy into electric power as an additional benefit, can be obtained by arranging and rotatably supporting lamellae, each with a base body and at least one photovoltaic module arranged on the base body, between the transverse bars.

According to a preferred embodiment of the invention, it may be provided that on the side of the longitudinal spar inner wall and the transverse spar inner wall at least one gutter element and / or a diaphragm element and / or a cable channel and / or an LED strip on the Longitudinal beams and / or the cross beams is arranged. Through the gutter elements rainwater can be derived from the lamellar roof. The cable channel allows the guidance of the connecting cables of the photovoltaic modules. These are advantageously spatially separated from the water supply in the gutter elements. The LED strip enables the lighting of the area covered by the louvered roof. there a uniform illumination of the covered space can be achieved if such LED strips are arranged on two opposite transverse bars or longitudinal beams or preferably on all cross beams and longitudinal beams. By means of the diaphragm elements, electrical and mechanical functional elements, as required for adjusting the fins and for dissipating the generated electric current, can be covered towards the covered interior. Accidental contact with these functional elements can thus be avoided and the risk of injury reduced. Also, the inwardly directed screw connections between the corner connector and the post or between the corner connector and the transverse and longitudinal members can be hidden. It is thus achieved a high-quality appearance of the frame of the lamellar roof. In the case of service, the gutter element and / or the diaphragm element and / or the cable duct and / or the LED strip can be easily removed and thus access to the electrical and mechanical functional elements produced.

A secure elevation of the post can be achieved in that the at least one post on its opposite side of the frame rests on a base plate, that along its longitudinal edges on the inner legs and the outer legs of the post mounting brackets are screwed, which facing the longitudinal edges of their base plate Partially enclosing areas and that in each case a base screw is screwed into the space enclosed by the mounting brackets, which engages with its thread in a cut into the end face of the inner leg or the outer leg threaded portion and establishes a connection between the base plate and the post. The item is advantageously held on the outer end surfaces of its inner leg and outer leg. As a result, high bending moments can be safely dissipated and transferred to the base plate. The base plate is advantageously secured by means of foundation screws on a foundation, whereby the post is securely held even under heavy loads.

The invention will be explained in more detail below with reference to an embodiment shown in the drawings. Show it: in a perspective top view, a lamellar roof in a perspective sectional view of a foundation with a transversely cut to its longitudinal extension post, in a perspective, cut transversely to the longitudinal extent of the slats representation of a slatted roof with closed slats, the slat roof shown in Figure 3 with open slats, in a lateral sectional view of a main body of a lamella, in a side view a portion of a photovoltaic module, in a perspective view from below a view of a corner of the lamellar roof, in an enlarged view a view from below of a corner region of the lamellar roof, in a perspective sectional view of a view in the direction of the longitudinal extent of a transverse spars, in a further perspective sectional view of a view on the cross beams, in a perspective sectional view of a view of a longitudinal spars in the area ch a last lamella of the lamellar roof, Figure 12 is a perspective view of a diagonal running

FIG. 1 shows a lamella roof 10 in a perspective plan view. A frame 12 of the lamellar roof 10 has two transverse struts 80 arranged at a distance from one another and two longitudinal struts 40 which are also spaced apart from one another. The transverse bars 80 are connected at the ends to the longitudinal bars 40. Thus, a rectangular frame 12 is formed. The frame 12 is supported in its corner areas by posts 30. Within the frame slats 20 are arranged. The slats 20 are aligned in their longitudinal extent in the direction of the longitudinal members 40. At the end, the slats 20 are pivotally fixed to the cross bars 80. The lamellae 20 can each be rotated about an axis of rotation. As a result, the slatted roof 10 can be opened and closed. The surfaces of the lamellae 20 facing upwards when the louvered roof 10 is closed are each formed by photovoltaic modules 50. In the exemplary embodiment shown, a photovoltaic module 50, which extends at least approximately over the entire length and width of the lamella 20, is arranged on the upper side of the lamella 20. However, it is also conceivable to provide two or more photovoltaic modules 50 along the longitudinal extension of the slats 20. The slats 20 are sealed in their closed position against each other and to the longitudinal beams 40 out that a rain-tight closed roof surface is formed. In swung-on slats 20, however, free spaces between the slats 20 are formed, through which sunlight can penetrate into the underlying space. The incidence of light can be regulated by selecting the position of the fins 20. Solar radiation impinging on the surface of the lamellae 20 is proportionately converted by the photovoltaic modules 50 into electrical current. Preferably, therefore, the slat roof 10 is aligned in a southern direction. The power is generated both in closed, partially open and fully open position of the fins 20. It is conceivable in a possible mode of operation of the slat roof 10, the inclination of the slats 20 automatically adjusted depending on the position of the sun (MPP tracking). As a result, the efficiency of power generation over non-tracking systems can be improved.

FIG. 2 shows in a perspective sectional view a foundation 60 with a post 30 cut transversely to its longitudinal extension. The foundation

60 is executed as a point foundation. Four foundation bolts 61 are anchored in the foundation 60. The foundation screws 61 are led up out of the foundation 60. They are arranged in the corners of a rectangle, in this case a square. A base plate 62 is of the foundation bolts

61 held. For this purpose, the rectangular, present square base plate 62 in their corner areas bores through which the foundation screws 61 are guided. On the foundation screws 61 nuts 61 .1 are screwed, on which washers 61 .2 rest. The base plate 62 is placed on these washers 61 .2. Washers 61 .2 are also pushed onto the foundation bolts 61 from above and secured with nuts 61 .1. The base plate 62 is thus held in its corners between the washers 61 .2 and the nuts 61 .1 in the longitudinal direction of the foundation screws 61.

The post 30 shown in section rests on the base plate 62. It is formed from two inner legs 30.1, 30.2 and two outer legs 30.3, 30.4. The two inner legs 30.1, 30.2 are arranged at an angle to each other. In the present case, the two inner legs 30.1, 30.2 are aligned at a right angle to each other. The outer legs 30.3, 30.4 are arranged in extension of the inner leg 30.1, 30.2. Between the outer legs 30.3, 30.4 thus the same angle is formed as between the inner leg 30.1, 30.2. The inner legs 30.1, 30.2 and the outer legs 30.3, 30.4 are connected to one another in a corner region of the post 30. Along the connecting line between the inner legs 30.1, 30.2, a corner reinforcement 30.5 is provided. The corner reinforcement 30.5 may be formed, for example in the form of a weld. It is conceivable that a corner reinforcement 30.5 is also provided between the outer legs 30.3, 30.4. Facing the base plate 62 mounting brackets 63 are frontally attached to the inner legs 30.1, 30.2 and the outer leg 30.3, 30.4. The mounting brackets 63 are formed omega-shaped. They lie with their legs on both sides of the surfaces of the respective inner leg 30.1, 30.2 and the outer leg 30.3, 30.4 and are connected by means of screws 63.1 with these. The mounting brackets 63 thus form in the end region of the inner and outer legs 30.1, 30.2, 30.3, 30.4 cylindrically enclosed spaces, in each of which the base plate 62 facing areas of the end faces of the inner and outer legs 30.1, 30.2, 30.3, 30.4 are introduced. Through recesses in the base plate 62 through base screws 64 are screwed into the space enclosed by the mounting brackets 63 spaces. The base screws 64 thereby cut with their threads in the end faces of the inner and outer legs 30.1, 30.2, 30.3, 30.4. As a result, four screw connections between the base plate 62 and the end faces of the inner and outer legs 30.1, 30.2, 30.3, 30.4 are formed, through which the post 30 is held on the base plate 62. The post 30 is thereby securely and resiliently connected to the base plate 62. The base plate 62 itself is mounted on the foundation bolts 61. By appropriate adjustment of the nuts 61 .1, the height and inclination of the base plate 62 and thus of the post 30 can be adjusted. Between the inner legs 30.1, 30.2 of the post 30, a drop tube 1 1 is arranged. It is guided through a corresponding hole in the base plate 62. Through the downpipe 1 1 rainwater can be derived from the slatted roof 10. FIG. 3 shows, in a perspective view cut transversely to the longitudinal extent of the slats 20, a slatted roof 10 with closed slats 20. The cut runs parallel to one of the transverse struts 80 of the slatted roof 10. omitted on the crossbars 80 indirectly or directly mounted components in the selected representation.

The section extends transversely to the longitudinal members 40. These have a first hollow chamber 40.1, as shown in detail in Figure 1 1. End side, the longitudinal beams 40 are attached to posts 30. The posts 30 are present partially transparent, so that introduced into the post 30 screw receivers 31 can be seen. The screw receptacles 31 are designed as blind holes in the corner region between the inner leg 30.1, 30.2 of the post 30, as can be seen enlarged in Figure 12. On the longitudinal beam 40, which is arranged next to a first lamella 20.1, a longitudinal channel element 90 and a longitudinal aperture element 100 are attached. At the opposite longitudinal beam 40, which runs along a last lamella 20.2 of the lamellar roof 10, an inlet element 190 and another longitudinal aperture element 100 are attached. The longitudinal panel element 100 carries an LED strip 160. On a post 30, the downpipe 1 1 with a corresponding pipe holder 1 1 .1 is attached. The downpipe 1 1 is covered by a post cover 32 to the covered space. For this purpose, the post cover 32 is attached to the two inner legs 30.1, 30.2 of the post 30. In the present illustration, the post cover 32 is shown partially transparent.

The lamellae 20 each have a main body 21, as shown in detail in FIG. The photovoltaic modules 50 are mounted on the main bodies 21. Preferably, the photovoltaic modules 50 are glued to the main body 21. The main body 21 are designed as hollow chamber profiles. Preferably, the main body 21 are formed of aluminum. In the end regions of the fins 20 water outlet spigot 27 are connected to the main body 21. They establish a connection to the interior of the main body 21, so that water can drain from it. In the basic bodies 21 connection cables 57, 57.2, 57.3 are laid, as shown in detail in Figures 10 to 13 and 15. The connection cables 57, 57.2, 57.3 are laid in sections in a cable receptacle 26 of the respective base body 21. The cable receptacle 26 is aligned in the direction of the longitudinal extent of the associated blade 20. It runs along the axis of rotation of the blade 20th

End side rocker arms 1 17, 1 18 are connected to the basic bodies 21. Here, a portion of the slats 20 long rocker arm 1 17 and another part of the slats 20 associated with short rocker arm. The long rocker arms 1 17 are hingedly connected to a lower linkage 1 15. The lower linkage 1 15 is designed as a rod-shaped U-profile, as shown in more detail in Figure 9. The lower linkage 1 15 surrounds the lower ends of the long rocker arms 1 17. It is pivotally connected thereto by means of lower pivot axes 1 17.1. The short rocker arms 1 18 are correspondingly connected by an upper linkage 1 16 hinged together. The connection to the short rocker arms 1 18 takes place via upper pivot axes 1 18.1. At one end, the upper linkage 1 16 articulated to an inner axle hole 1 17.2 of the nearest long rocker arm 1 18 is attached. An outer upper linkage 1 16.1 connects the short rocker arm 1 18 of the last slat 20.2 with the long rocker arm 1 18 of the adjacent slat 20th

In extension of the lower linkage 1 15 a linear actuator 1 10 is arranged. The linear actuator 1 10 is connected at the end to the lower linkage 1 15. By a linear adjustment of the linear actuator 1 10, the lower linkage 1 15 is adjusted. As a result, the long rocker arms 17 and the associated blades 20 are pivoted about their axes of rotation. The movement of the long rocker arm is transmitted via the upper linkage 1 16 and the outer upper linkage 1 16.1 of each one long rocker arm 1 17 on the short rocker arm 1 18. As a result, the short rocker arms 1 18 and the associated blades 20 are pivoted about their axes of rotation. In the present case, the linear actuator 1 10 is designed as a hydraulic cylinder. This has a cylinder 1 1 1 and a piston 1 12. The cylinder 1 1 1 is the end with a cylinder port 1 1 1 .1 attached to a cylinder holder 1 13. The cylinder holder 1 13 is attached by means of fastening screws 1 13.1 on the cross bars 80. The cylinder 1 1 1 is thus fixed to the crossbars 80 fixed. The piston 1 12 is connected at the end to a piston connection 12.1 with the lower linkage 15. In the region of the transition from the cylinder 1 1 1 to the piston 1 12, an actuator holder 1 14 is provided.

In the position shown in Figure 3, the piston 1 12 of the linear actuator 1 10 is extended. Thus, the linkages 1 15, 1 16 in the direction of the last slat 20.2 and the slats 20 via the rocker arms 1 17, 1 18 placed in their closed position.

FIG. 4 shows the lamellar roof 10 shown in FIG. 3 with opened lamellas 20. In contrast to FIG. 3, the piston 12 of the linear actuator 110 has moved into the cylinder 11. As a result, the linkages 1 15, 1 16 in the direction of the first blade 20.1 and the slats 20 via the rocker arms 1 17, 1 18 placed in their open position.

By adjusting the linear actuator 1 10 thus the slats 20 can be adjusted in any rotational positions between their fully open and fully closed positions. In the embodiment shown, the slats can be rotated approximately 90 ° out of the roof plane. However, it is also conceivable that the slats 20 are pivotable at a larger angle, for example up to 180 °.

FIG. 5 shows a side view of a base body 21 of a lamella 20. The base body 21 is designed as a hollow chamber profile. It has an upper cover 21 and a spaced-apart lower cover 23. The upper cover 21 is made flat in some areas. It thus has a top side in some areas 22.1. Along the length of the Main body 21 is a notch 22.4 formed in the upper cover 21. The notch 22.4 is preferably arranged centrally to the upper cover 21. Along the opposite edge regions of the upper cover 21 PV gaskets 22.3, 22.5 are formed in this. They run along the longitudinal extent of the lamella 20. The edges themselves form PV sealing systems 22.2, 22.6.

The lower cover 23 is connected by means of partitions 25.1, 25.4 with the upper cover 21. The separations 25.1, 25.4 are formed as webs. Along the notch 22.4 a cylinder profile 25.3 is arranged. The longitudinal axis of the cylinder profile 25.3 is aligned in the direction of the longitudinal extension of the main body 21. It connects the top cover 22 along the apex line of the notch 22.4 with the bottom cover 23.

The lower cover 23 is formed convexly curved transversely to the longitudinal extent of the lamella 20. It thus forms an outwardly facing, convexly shaped bottom 23.1 of the lamella 20. The curvature is formed differently strong in different sections of the bottom 23.1. A middle lower side section 23.3 has a comparatively small curvature. An outer bottom portion 23.2 is more curved than the middle bottom portion 23.3. The outer lower side portion 23.3 is pivoted away with the louvered roof 10 from the covered space. An inner bottom portion 23.4 has the strongest curvature of the bottom 23.1. The inner lower side portion 23.4 connects opposite to the outer lower side portion 23.2 to the central lower side portion 23.3. He is thus pivoted with the louvered roof 10 to the covered space.

The outer lower side portion 23.2 terminates with the outer partition 25.1. The upper cover 22 projects beyond the lower cover 23 at the outer end of the main body 21. The outer end of the main body 21 is the area which is pivoted away with the louver 10 pivoted away from the roofed interior. Starting from the lower cover 23, the outer runs Separation 25.1 initially straight. On the side of the upper cover 22, the outer partition 25.1 is formed in the form of a partial segment of a cylinder wall. Between the rectilinear portion of the outer partition 25.1 and the protruding portion of the upper cover 22, a first cavity 24.1 of the main body 21 is formed. Starting from the upper cover 22, a retaining segment 25.2 protrudes into the first cavity 24.1. The holding segment 25.2 forms a further sub-segment a cylinder wall. The retaining segment 25.2, a portion of the upper cover 22 and the cylindrically shaped portion of the outer partition 25.1 enclose a second cavity 24.2. The second cavity 24.2 is cylindrical. Its central axis is aligned in the direction of the longitudinal extent of the lamella 10. For the first cavity 24.1 towards the second cavity 24.2 is opened by a longitudinal slot which is formed between the end of the retaining segment 25.2 and the outer partition 25.1. A lamellar seal 71 is fixed with a holding portion 71 .1 in the second cavity 24.2. For this purpose, the holding portion 71 .1 is inserted through the longitudinal slot in the second cavity 24.2. The holding portion 71 .1 is wedge-shaped. On the holding portion 71 .1 a sealing system 71 .2 of the disk seal 71 is formed. The sealing system 71 .2 bridges the distance between the outer end of the lower cover 23 and a sealing web 22.7. The sealing web 22.7 is integrally formed on the outer PV sealing system 22.2 of the upper cover 22. The sealing system 71 .2 thus closes the first cavity 24. 1 to the lower side of the slat. It forms a sealing surface 71 .3 outwards. The sealing surface 71 .3 goes into the underside 23. 1 of the lower cover 23 without edges. It is thus aligned in extension of the bottom 23.1 in the region of the outer bottom portion 23.2. On its side facing the sealing web 22.7, the sealing system 71 .2 is closed by a sealing end 71 .4. The seal end 71 .4 connects to the seal land 22.7.

Between the outer partition 25.1 and the cylinder profile 25.3, a third cavity 24.3 of the main body 21 is formed. The third cavity 24.3 is closed to the top of the blade 20 from the top cover 22. Opposite limits the lower cover 23 with its outer lower side portion 23.2 the third cavity 24.3.

A fourth cavity 24.4 is formed within the cylinder profile 25.3. He has accordingly a cylindrical cross-section.

Between the inner partition 25.4 and the cylinder profile 25.3, a fifth cavity 24.5 of the main body 21 is formed. The fifth cavity 24.5 is closed to the top of the lamella 20 from the top cover 22. Opposite limits the lower cover 23 with its central lower side portion 23.3 the fifth cavity 24.5.

In the fifth cavity 24.5, the cable receptacle 26 is arranged. The cable receptacle 26 is formed by a lower and an upper sub-segment 26.1, 26.2. The sub-segments 26.1, 26.2 are integrally formed on the inner partition 25.4. The sub-segments 26.1, 26.2 form sections of a cylindrical wall of the cable holder 26. The sub-segments 26.1, 26.2 are separated by a slot 26.3. The slit 26.3 is disposed opposite to the inner partition 25.4. The cable receptacle 26 thus forms a cylindrical cavity, the central axis of which is aligned in the direction of the longitudinal extent of the lamella 20. The slot 26.3 provides access to the cable channel 26. It connects the cable channel 26 with the fifth cavity 24.5.

The inner lower side portion 23.4 of the lower cover 23 projects beyond the upper cover 22. Between the inner lower side portion 23.4, the upper cover 22 and the inner partition 25.4, a sixth cavity 24.6 is formed. The inner lower side section 23.4 is closed by a sealing edge 23.5. The sealing edge 23.5 is formed by a rounded edge of the lower cover 23. The inner lower side portion 23.4 of the lower cover 23 is so strongly curved that the sealing edge 23.5 is arranged in extension or approximately in extension of the upper cover 22. In this case, the sealing edge 23.5 is arranged at a distance from the inner PV sealing installation 22.6 of the upper cover 22. The distance between the sealing edge 23.5 and the PV sealing system 22.6 forms a water inlet 24.7. This provides access to the sixth cavity 24.6.

Along the side edges of the upper cover 22, a PV support seal 70 is arranged in each case. The PV contact seals 70 each have a fastening section 70.1, a support surface 70.2, a sealing lip 70.3 and a contact edge 70.4. The PV support seals 70 surround the side edges of the upper cover 22 oriented in the direction of the longitudinal extension of the lamella 20. They are fastened with their fastening sections 70.1 in the PV seal receptacles 22.3, 22.5. The PV-seal receptacles 22.3, 22.5 are inserted as longitudinal grooves along the lateral edges of the upper cover 22 in the upper side 22.1. The bearing surfaces 70. 2 are aligned in the same direction as the upper side 22. 1 of the upper cover 22. The photovoltaic modules 50 shown in FIG. 1 can be applied to them. The photovoltaic modules 50 are thus arranged slightly spaced from the upper side 22. 1 of the upper cover 22. In the gap thus formed, an adhesive is introduced. With this, the respective photovoltaic module 50 is glued to the top 22.1 of the main body 21. The thickness of the PV support seal in the area of its support surface 70.2 is selected so that there is an optimum thickness of the adhesive gap. Excess glue is picked up by the notch 22.4. Preferably, a permanently elastic adhesive is used. In particular, silicone may be provided as an adhesive. The PV pad seals seal the photovoltaic modules 50 along their edges opposite the body 21. For this purpose, the sealing lips 70.3 at least partially surround the outer edges of the photovoltaic modules 50. The abutment edges 70.4 are arranged opposite to the sealing lips 70.3. They include the PV sealing systems 22.2, 22.6 as outer edges of the upper cover 22. Thus, the adhesive gap formed between the photovoltaic module 50 and the upper cover 22 is protected from moisture penetration by the PV support seals 70.

The main body 21 is made of metal, preferably of aluminum. Due to the design as hollow chamber profiles, it has a low weight at the same time high stability. This ensures that the lamellas 20 are statically stable against snow.

The underside 23.1 of the slats 20 is preferably designed to be reflective. It is powder coated in the present case. Particularly suitable is a white powder coating provided. However, colored coatings can be applied. It is also conceivable to make the underside 23.1 metallic. The underside 23.1 is designed diffusely reflecting. It is also conceivable to design the underside 23.1 in a directionally reflective manner.

Due to the good reflectivity of the underside 23.1, light incident on the underside 23.1 of the lamellae 20 is at least partially guided into the space below when the lamella roof is open. As a result, a high light entry into the covered space is achieved. Another portion of the incident sunlight is reflected from the bottom 23.1 of a lamella 20 on photovoltaic modules 50 adjacent lamellae. The light is converted into electrical energy there. As a result, the overall efficiency of the photovoltaic system can be improved. When the louvered roof is closed, a bright appearance of the roof side facing the covered interior is achieved.

Due to the convexly curved bottom 23.1, a uniform illumination of the covered space is achieved when the louvered roof 10 is open. In this case, the incident light of the sun is not reflected by the convex shape of the successive and identically aligned slats 20 disturbing in one direction. Rather, the convex underside 23.1 causes the incident light to be directed in different directions in accordance with the respective inclination of the underside 23.1 at the reflection location. As a result, the underlying space is evenly illuminated.

Due to the small curvature of the middle lower side portion 23.3 10 large free spaces between the slats 20 are created with the slat roof open so that much light can penetrate. By compared to the middle bottom portion 23.3 slightly stronger curvature of the outer Bottom portion 23.2, which is pivoted when opening the louvered roof 10 upwards from the roof level, a sufficient proportion of solar radiation is directed into the covered space even with small opening of the fins 20 and obliquely incident sunlight. The strong curvature of the inner lower side portion 23.4 causes the incident light is reflected in the covered space even with fully swung slats 20 and oblique incidence of light. The strong curvature also makes it possible that the lamellae 20 do not or only slightly protrude into the covered space during their rotation. As a result, the risk that the slats 20 collide with their pivotal movement with arranged under the slatted roof 10 objects, reduced. Furthermore, an upwardly open cavity (sixth cavity 24.6) with a large cross-section is created by the curved up to the level of the upper cover 22 inner bottom portion 23.4, in which large amounts of rainwater can be derived.

FIG. 6 shows a side view of a section of a photovoltaic module 50. The photovoltaic module 50 is covered by a solar glass 51. For this purpose, a low-iron solar glass 51 is preferably used. The solar glass 51 is designed by a thermal bias as single-pane safety glass. Under the solar glass 51 solar cells 53 are arranged. To achieve high efficiency monocrystalline solar cells are used. The solar cells 53 are designed as back-contacted solar cells. However, it is conceivable to use other solar cell types. For example, thin-film solar cells can be provided which have an improved efficiency, especially in the case of unfavorable roof alignment.

In the present case, the solar cells 53 have an edge length of 156 mm. The width of the solar glass 51 is set slightly larger than the edge length, so that the solar cells are completely covered and encapsulated by a laminate 54. In the present case, the solar glass 51 has a width between 160 mm and 180 mm, preferably between 165 mm and 170 mm, in particular 166 mm. The width of the fins 50 is adapted to the width of the photovoltaic modules 50 used. It is conceivable to use solar cells 53 with an edge length of 125 mm. Then the width of the solar glass is used in a range between 130mm and 150mm, preferably between 130mm and 140mm, especially 135mm. The fins 20 can then be made narrower in comparison to the fins 20 with larger solar cells 53.

The solar cells 53 are connected to each other by means of cell connectors 52. In this case, the solar cells 53 of a photovoltaic module 50 are electrically connected in series. Each photovoltaic module 50 has only one cell string with solar cells 53 arranged behind one another. On the rear side, the photovoltaic module 50 is closed by a backsheet 55. The backsheet 55 forms an electrical insulation of the solar cells 53 and the cell connector 52 relative to the main body 21 of the lamella 20th

From the backsheet connections 56 are led out. Each photovoltaic module 50 has a positive and a negative terminal (56.1, 56.2), as shown in more detail in FIG. In the section of the photovoltaic module 50 shown in FIG. 6 in the region of an external solar cell 53, only one connection (56, 56.1, 56.2) is arranged. The connections (56, 56.1, 56.2) are designed as connection lugs. They are arranged in the opposite end regions of the photovoltaic modules 50.

The connections 56, 56.1, 56.2 are guided out of the laminate 54 such that they are arranged in the notch 22.4 of the base body 21 shown in FIG. 5 when the photovoltaic module 50 is mounted on the base body 21.

The photovoltaic module 50 can be glued as a prefabricated unit on the top 22.1 of the main body 21 shown in Figure 5. In this case, one or more, successively arranged photovoltaic modules 50 may be provided per slat 20. A single, continuous photovoltaic module 50 per blade 20 offers the advantages of a continuous glass surface of the blade 20 and a reduced Verschaltungsaufwands. Shorter photovoltaic modules 50 can on the other hand, they are easier to produce in a lamination process. Furthermore, in the case of a plurality of shorter photovoltaic modules 50, differences in the thermal expansion between the photovoltaic modules 50 and here in particular the solar glasses 51 and the main body 21 can be better compensated for each slat.

FIG. 7 shows, in a perspective view from below, a view of a corner region of the lamellar roof 10. The lamellar roof 10 is closed so that the curved undersides 23.1 of the lamellae 20 are aligned towards the covered space. End the blades 20 are completed by rocker arm 1 17, 1 18. The water outlet spigots 27 are fastened in the end region of the slats 20 on the underside 23. 1 of the main body 21. They are inserted in a transverse channel element 150. The transverse gutter element 150 is attached along the crosspiece 80. Below the transverse channel element 150, a transverse aperture element 120 is arranged. At the longitudinal beams 40 shown in section, the inlet element 190 and the longitudinal panel element 100 are attached. Towards the covered interior, the inlet element 190 forms an inlet aperture 194. In the region of the longitudinal aperture element 100 and the transverse channel element 150 LED strips 160 are arranged.

The water outlet nozzle 27 form a drain from the sixth cavities 24.6 of the main body 21 of the fins 20. This allows water from the sixth cavity 24.6 in the transverse channel element 150 and from there into the downpipe 1 1 are passed. As shown in Figure 5, the sixth cavity 24.6 is open to the lamella upper side. Thus, rainwater from the roof surface via the sixth cavity 24.6, the water outlet nozzle 27, the transverse channel element 150 and the downpipe 1 1 run off.

The transverse channel element 150 and the longitudinal aperture element 100 abut one another in the corner of the laminar roof 10. They are the same design in their profile and gap-free or joined together with a small gap, so that a uniform appearance is achieved. The LED strips 160 are formed at the same height. They allow glare-free illumination of the covered interior. Through the transverse channel element 150 and the transverse diaphragm element 120, the elements of the blade adjustment shown in FIGS. 3 and 4 are covered. The longitudinal panel element 100 and the inlet element 190 cover according to the longitudinal beams 40. From the perspective of the covered space thus a high quality and uniform appearance of the frame 20 is achieved, the components used have additional functionalities. They can be easily disassembled for maintenance.

FIG. 8 shows, in an enlarged view, a view from below of a corner region of the lamellar roof 10. In this case, the longitudinal diaphragm element 100 shown in FIG. 7 is hidden for better illustration.

The transverse gutter element 150, facing the covered interior space, has a transverse gutter outer wall 154 and a transverse gutter diaphragm 151, between which the LED strip 160 is arranged. The transverse gutter element 150 is attached at the end to a transverse gutter finisher 158. The transverse gutter 158 is attached to the longitudinal spar 40. The outer contour of the transverse gutter finisher 158 corresponds to the cross section of the transverse gutter element 150, so that this end can be pushed onto the transverse gutter closure 158 and sealed in a watertight manner.

At the inlet aperture 194 of the inlet member 190 at an angle an inlet bottom 195 is formed. The inlet floor 195 is aligned in the direction of the longitudinal bars 40. He has at the end of a holding approach 195.1. Opposite to the retaining lug 195.1, an upper longitudinal web 42.1 is integrally formed on a longitudinal longitudinal inner wall 42 of the longitudinal member 40. Spaced to the upper longitudinal spar web 42. 1, a lower longitudinal spar bar 42. 2 is connected to the longitudinal spar inner wall 42. The longitudinal spar webs 42.1, 42.2 are aligned in the direction of the longitudinal extension of the longitudinal spar 40. They have facing each other locking lugs on. In the locking lugs staples 170 are locked. In the section shown two brackets 170 are arranged. The staples 170 have two staple legs 171, 172. These are in one acute angle connected and aligned with the opposite longitudinal spar webs 42.1, 42.2 out. The Klannner legs 171, 172 have at the end angled executed clip holding portions 171 .1, 172.1. These engage in the latching lugs of the longitudinal spar webs 42.1, 42.2. Due to the clamping force of the clutches 170, the cleat arms 171, 172 are pushed apart, so that the claw holding portions 171 .1, 172.1 are pressed against the longitudinal bars 42,1, 42.2 and held by the locking projections. The brackets 170 are fixed to the longitudinal spars 40. Accordingly, such brackets 170 can also be attached to the crossbars 80.

The clamps 170 each have a clip leg 171, 172 clamping sections 173. These are formed out of the clip legs 171, 172. The clamping portions 173 are formed such that they engage the retaining lugs 195.1 on the transverse and longitudinal bars 80, 40 fastened assemblies and thus hold them on the transverse and longitudinal bars 80, 40. In the detail shown, the clamping section 173 of the bracket 170, which is further disposed toward the corner of the lamellar roof 1 1, engages in the retaining lug 195. 1 of the inlet element 190. As a result, the inlet element 190 is held on the longitudinal bars 40.

Opposite to the longitudinal spar inner wall 42, a longitudinal spar outer wall 43 is arranged, which is transferred via a longitudinal spar-supporting edge 44 in a longitudinal spar-paragraph 45. In the longitudinal spar inner wall 42 longitudinal beam mounting holes 46 are introduced, whose function is described in more detail to the following figures.

FIG. 9 shows a perspective sectional view of a view in the direction of the longitudinal extent of a transverse spars 80. On the transverse spars 80, the blades 20 are fixed on the front side and rotatably.

The crossbar 80 has a vertically arranged transverse crossbar inner wall 82, which is aligned in the direction of the slats 20. Outwardly and spaced from the crossbar inner wall 82 is a crossbar outer wall 84 arranged. The transverse spar outer wall 83 merges via a horizontally oriented cross-beam support edge 84 into a cross-beam shoulder 85. The transverse spars paragraph 85 and the transverse spar inner wall 82 are connected at the end to a cross-beam cover 87. Opposite connects a cross-beam floor 81, the cross-member inner wall 82 with the cross-member outer wall 83. Thus, a hollow chamber (second hollow chamber 80.1) of the cross member 80 is formed. The cross-beam cover 87 is extended beyond the cross-member inner wall 82 out and forms the end of a stepped lowered bearing bracket holding projection 88 with a bearing support surface 88.1. Between the cross-member inner wall 82 and the bearing angle holding projection 88, a cross-member attachment 87.1 is integrally formed on the cross-member cover 87. The cross-beam approach 87.1 is offset from the cross-member inner wall 82 as aligned. It serves to stabilize the cross-beam cover 87th

The crossbar floor 81 is extended beyond the crossbar inner wall 82 also. It forms a transverse end-retaining lug 81 .1 end. The cross-panel-holding approach 81 .1 is formed as a longitudinally in the end face of the cross-beam bottom 81 introduced, substantially V-shaped groove. This has a bead on the end.

On the cross-member inner wall 82, an upper cross-member web 82.1 and at a distance to a lower cross-member web 82.2 are integrally formed. They have mutually facing latching lugs, as they are already described for the longitudinal bars 42.1, 42.2 of the longitudinal members 40. The transverse spar webs 82.1, 82.2 are arranged on the side of the transverse spar inner wall 82 facing away from the second hollow chamber 80.1 and aligned in their longitudinal extent corresponding to the longitudinal extent of the transverse spar 80.

The transverse bars 80 rests with its cross-member support edge 84 on the upper side of the second inner leg 30.2 of the post 30. He is held vertically by it. End side, a transverse leg 202 of a corner connector 200 is inserted into the second hollow chamber 80.1 of the cross member 80. Corner connector 200 connects to longitudinal beam 40 shown in FIG. A lamella 20 of the lamellar roof 10 is shown in a longitudinal section. The longitudinal section runs along the cable receptacle 26 of the lamella 20. In the cable receptacle 26, the connection cable 57 of the photovoltaic module 50 is guided. End of a bearing sleeve 142 is screwed into the cable holder 26. The bearing sleeve 142 has a thread 142.2 for this purpose. As shown in Figures 10 and 15, the bearing sleeve 142 is penetrated by a longitudinal bore 142.3. At the end, the bearing sleeve 142 has a tool attachment 142.1. The tool attachment 142.1 has a larger diameter than the threaded portion of the bearing sleeve 142. He is also penetrated by the longitudinal bore 142.3. Between the thread 142.2 and the tool attachment 172.1, as also shown in FIG. 15, a sleeve attachment 142.4 is provided. On the sleeve approach 142.4 a bearing, in this case a ball bearing 141, attached. The tool attachment 142.1 abuts against the ball bearing 141 and blocks it axially. Following the ball bearing 141, a rocker arm 1 17, 1 18 is pushed onto the sleeve approach 142.4. For this purpose, a rotary axis breakthrough 1 19 is introduced into the rocker arms 1 17, 1 18, as shown in Figures 10 and 15. In the image detail shown a long rocker arm 1 17 is shown as representative, but the statements also apply to slats 20, which short rocker arms 1 18 are assigned. The ball bearing 141 is attached to the crossbar 80 with a bearing angle 140. The bearing angle 140 has a support leg 140.1 and a bearing leg 140.2 arranged at an angle thereto. The bearing angle 140 is on with its support leg 140.1 on the bearing support surface 88.1 of the cross member cover 87. It is connected thereto by a screw connection shown in FIG. The ball bearing 141 is fixed at its periphery to the bearing leg 140.2. For this purpose, the bearing leg 140.2 has a bearing seat 140.4 designed as a bore, as can be seen in more detail in FIG. By the bearing sleeve 142 thus the ball bearing 141 and the rocker arm 1 17, 1 18 are connected to the main body 21 of the blade 20. Thus, the axis of rotation of the blade 20 along the cable receptacle 26. The plate-shaped formed rocker arm 1 17, 1 18 is pressed against the front side of the main body 21 and thereby closes the cavities shown in Figure 5 24.1, 24.2, 24.3, 24.4, 24.5, 24.6 end side , The bearing angle 140 is preferably made of metal. Also, the bearing sleeve 142 is made of metal. In conjunction with the likewise made of metal crossbars 80 so high, acting on the fins 20 forces can be derived on the post 30. Such forces can be caused by the weight of the slats 20 and, for example, by a snow load.

The rocker arms 1 17, 1 18 are also made of metal. As a result, the required rotational forces of the linkages 1 15, 1 16 via the rocker arms 1 17, 1 18 are transmitted to the fins 20. The design in metal ensures a long service life of the mechanically heavily loaded rocker arms 1 17, 1 18.

The connection cable 57 of the photovoltaic module 50 is led out of the slat 20 through the longitudinal bore 142.3 of the bearing sleeve 142. The diameter of the longitudinal bore 142.3 is greater than the diameter of the connecting cable 57 chosen. This avoids that upon rotation of the blade 20 at the outlet of the connecting cable 57 from the bearing sleeve 142 high torsional forces are transmitted to the connecting cable 57.

The connection cables 57 of the lamella 20 are guided by the bearing sleeves 142 to a cable channel 130. The cable channel 130 is open to the top. It has a cable channel inner wall 131 and a cable channel holding portion 132. These are connected at the end to a cable channel bottom 133. The cable channel holding portion 132 is guided along the transverse spar inner wall 82 and held by the latching lugs of the cross-member webs 82.1, 82.2. Thus, the cable channel 130 is easy to install and releasably secured to the crossbars 80. On the cross member 80 on the opposite side of the lamellar roof 10 such a cable channel 130 is also provided. In accordance with the preceding description, the connecting cables 57 of the photovoltaic modules 50 oppositely poled per lamella 20 are inserted in these. The connection cables 57 are interconnected in the cable channels 130, as shown in more detail in FIG. 16. The connecting cables 57 are to 57.1 by means of PV connectors connected with each other. The cable channel 130 is preferably made of plastic. However, it is also conceivable to produce the cable channel 130 from a metal sheet.

The present in the selected image section long rocker arm 1 17 are connected to each other by means of the lower linkage 1 15. For this purpose, the lower linkage 1 15 U-shaped and pushed from below onto the plate-shaped rocker arm 1 17. Through the legs of the lower linkage 1 15 holes are guided. These are aligned with lower axle holes 1 17.3 of the long rocker arms 1 17 aligned. Through the holes of the linkage 1 15 and the lower axle holes 1 17.3 lower pivot axes 1 17.1 are plugged. These each form a rotatable connection between the lower linkage 1 15 and the long rocker arm 1 17. By a linear displacement of the lower linkage 1 15 in the direction of the longitudinal extension of the cross member 80 thus the long rocker arm 1 17 and with the long rocker arm 1 17 connected slats 20 pivoted about the predetermined by the ball bearings 141 axes of rotation.

The rotatable connection between the upper articulation 1 16 shown in Figures 3 and 4 and the short rocker arms 1 18 is formed according to the connection between the lower linkage 1 15 and the long rocker arms 1 17.

To the cross-panel-holding approach 81 .1 of the cross-beam bottom 81, the cross-member element 120 is attached. For this purpose, a transverse diaphragm holding portion 121 is inserted into the transverse diaphragm holding attachment 81 .1 and locked with this. Opposite to the transverse diaphragm holding section 121, a transverse diaphragm inner web 122 and a transverse diaphragm outer web 123 are arranged. The transverse diaphragm inner web 122 and the transverse diaphragm outer web 123 are oriented, starting from a bottom surface of the transverse diaphragm element 120, obliquely upwards to the fins 20 in the direction of pointing. On the transverse aperture outer web 123, the transverse channel element 150 is fitted with a cross-diaphragm web receptacle 157 designed for this purpose. For this purpose, the transverse diaphragm web receptacle 157 has a groove enclosed by two lateral projections, into which the transverse diaphragm outer web 123 engages. The transverse channel element 150 is detachable with a clamping element 124 connected to the cross-panel element 120. For this purpose, the clamping element 124 is fixed between the transverse panel inner web 122 and the transverse panel outer web 123.

The cross-member element 120 is in this case made of plastic. However, it is also conceivable to produce the cross-panel element 120 made of metal.

At the cross-diaphragm bridge receptacle 157 includes a transverse channel LED strip receptacle 156. This is designed as a cavity open towards the covered interior. The opening of the cross-diaphragm web receptacle 157 is bordered laterally by the transverse-channel diaphragm 151. The transverse channel LED strip receiving 156 is followed by the actual channel region of the transverse channel element 150. This is formed by the transverse gutter outer wall 154, a transverse gutter bottom 152 and a transverse gutter inner wall 153. At the top, the transverse gutter element 150 is opened by a transverse gutter inlet 155 extending along the longitudinal extent of the transverse gutter element 150. In the closed position of the slats 20 shown, the water outlet nozzle 27 is arranged such that a water outlet 27.1 of the water outlet nozzle 27 is inserted through the transverse gutter water inlet 155 into the transverse gutter element 150. Rainwater can thus be derived from the sixth cavity 24.6 through the water outlet nozzle 27 and the transverse channel element 150.

The transverse gutter element 150 is in the present case made of plastic. However, it is also conceivable to manufacture the transverse gutter element 150 from metal.

In the transverse channel LED strip receptacle 156, the LED strip 160 is arranged. An LED board 163 is mounted in an LED strip housing 161. The LED strip housing 161 is preferably made of metal and has on its outer side on cooling ribs. On the LED board 163, a plurality of LEDs are arranged, which are aligned to the space covered by the louvered roof 10 space. The heat loss generated by the LEDs is dissipated via the LED strip housing 161 and the cooling fins arranged thereon. To the covered space, the LED strip housing 161 is from a LED Mold cover 162 completed. The LED strip cover 162 is made of a transparent material, in particular of a transparent plastic. It may have a structuring to allow a uniform light distribution. The front side of the LED strip cover 162 is fitted in the cross-channel panel 151. As a result, the LED strip cover 162 forms a flat surface with the transverse-channel panel 151. Laterally, the LED strip cover 162 forms LED abutment edges 162.2, with which it rests along the edges of the transverse channel aperture 151. For connection to the LED strip housing 161 LED latching receptacles 162.1 are integrally formed on the LED strip cover 162, which engage in corresponding LED locking inserts 161 .1 of the LED strip housing 161.

Through the cable channel 130 and the transverse channel element 150, the current flow and the water supply are spatially separated. The arrangement of the cable channel 130 under the cross-beam cover 180 and the bearing brackets 140 it remains dry even in heavy rain. The introduction of the connecting cable 57 from the sealed interior of the slats 20 through the bearing sleeve 142 in the cable channel 130 prevents moisture along the connecting cable 57 can get into the cable channel 130. By these measures weathering of the connection cable 57 and the PV connector 57.1 is counteracted. The cable channel 130 and / or the transverse panel element 120 and / or the transverse channel element 150 can be easily and quickly mounted on the transverse struts 80 and, if necessary, also dismantled again. In case of service, access to the mechanically moving parts of the lamellar linkage as well as to the external wiring of the photovoltaic modules 50 can thus be made easily possible. In normal operation, the electrical and mechanical functional elements are covered by the transverse channel element 150 and the cross-member element 120. As a result, the functional elements are arranged protected. The risk of injury from the moving mechanical parts is reduced. From the covered interior, there is a high-quality appearance of the frame construction of the lamellar roof 10. FIG. 10 shows, in a further perspective sectional view, a view of the transverse struts 80. For better illustration, the transverse struts 80, the post cover 32 of the post 30 and parts of the post 30 are shown partially transparent. Identical components are the same as previously introduced.

The section runs along the cable receptacle 26 of a lamella 20. The bearing sleeve 142 is guided through the ball bearing 141 and the axis of rotation breakthrough 1 19 to the cable receptacle 26 of the main body 21 of the blade 20 and screwed into it. The bearing sleeve 142 has for this purpose a preferably self-tapping thread 142.2. The tool attachment 142.1 makes it possible to use a suitable tool for screwing in the bearing sleeve 142. The connection cable 57 is guided out of the blade into the cable channel 130 through the longitudinal bore 142.3 of the bearing sleeve 142. In this connection cables 57 are connected by means of the PV connectors.

The transverse leg 202 of the corner connector 200 is inserted into the hollow chamber (second hollow chamber 80.1) of the transverse spar. In the transverse leg 202 threaded holes 203 are introduced. In the threaded holes 203 screws can be screwed and thus a connection to the crossbars 80 are made. The screws are guided by the cross-member inner wall 82. They are so arranged by the cable channel 130, and the transverse channel element 150 and the cross-member element 120 hidden. For a mounted lamellar roof 10 therefore no screws are visible from the outside.

FIG. 11 shows, in a perspective sectional view, a view of a longitudinal spar in the area of the last lamella 20.2 of the lamellar roof 10. The section runs transversely to the longitudinal extent of the lamellas 20. For better illustration, the transverse trough element 51 and the LED bar 160 are along the Querholmens 80 not shown. The transverse spar inner wall 82 is shown transparent.

The photovoltaic modules 50 are laterally on the PV pad seals 70. In between, the photovoltaic modules 50 are elastically bonded to the base body 21 of the lamellae 20. The connection cables 57 are initially in the notch 22.4 guided. They are passed through a hole in each case from the notch 22.4 in the fifth cavity 24.5 and from there in a loop through the slot 26.3 in the cable receptacle 26. These are by the linkages 1 15, 1 16, 1 16.1 and the rocker arms 1 17, 1 18 adjusted to its open position.

As already described, the longitudinal bars 40 have a longitudinal inner wall 42 and a longitudinal longitudinal outer wall 43 arranged at a distance therefrom. Towards the top, the longitudinal spar outer wall 43 merges via a vertically aligned longitudinal support edge 44 into a longitudinal spar shoulder 45. The longitudinal beam 40 forms the first hollow chamber 40.1, which is closed at the top by a longitudinal spar cover 47 and down by a longitudinal spar base 41. The longitudinal spar cover 47 and the longitudinal spar bottom 41 are each about the longitudinal spar inner wall 42 via. Facing the fins 20, a retaining lug 47.1 is integrally formed on the longitudinal fulcrum cover 47. The longitudinal spar base 41 has at its end a longitudinal diaphragm holding lug 41 .1. The longitudinal beams 40 is thus formed according to the transverse beams.

At the retaining lug 47.1 of the longitudinal spar cover 47, the inlet element 190 is attached. It has for this purpose an inlet holding portion 192 which engages in the holding projection 47.1. At the inlet-holding portion 192, a cylindrical, longitudinally slotted inlet seal holder 193 is arranged. Opposite to the inlet holding portion 192, the inlet member 190 is closed by an inlet portion 191.

The inlet seal holder 193 is formed in its upper portion comparable to the holder for the plate seal 71 on the base bodies 21. Accordingly, the inlet section 191 is modeled on the sealing web 22.7 of the main body 21. A fin seal 71 is defined between the inlet seal holder 193 and the inlet portion 191. The sealing surface 71 .3 of the lamellar seal 71 is arranged correspondingly in the travel of the sealing edge 23.5 of the last lamella 20.2. When closing the slats 20, the sealing edge 23.5 of the last slat 20.2 against the sealing surface 71 .3 of the Inlet element 190 attached lamellar seal 71 pressed waterproof. Rainwater can thus run from the inlet element 190 via the inlet section 191 and the water inlet 24. 7 (see FIG. 5) into the sixth cavity 24.6 of the last lamella 20.2 and from there via the water outlet connection 27 into the transverse channel element 150.

When pivoting the slats 20 whose sealing edges 23.5 pressed against the sealing surfaces 71 .3 of the plate seals 71 of the adjacent slats 20 watertight. Rainwater can be removed from the upper side of the lamella on the open water inlets 24.7 into the sixth hollow chambers 24.6 of the base body 21 and from there via the water outlet nozzle 27, the transverse channel element 150 and the downpipe 1 1.

To the inlet seal holder 193 of the inlet member 190 includes the inlet aperture 194, to which the inlet bottom 195 is formed. The inlet bottom 195 is, as described to Figure 8, fixed by means of brackets 170 on the longitudinal spar webs 42.1, 42.2. The inlet panel 194 is adjoined by the longitudinal panel element 100. At the the roofed interior facing aperture portion a longitudinal aperture connecting web 101 is integrally formed. The longitudinal aperture connecting web 101 is aligned in the direction of the lower longitudinal spar web 42.2 out. It is connected to the latter by means of the clamps 170, as described for FIG. 8 for the inlet element 190. In its further course, the longitudinal aperture element 100 has a longitudinal aperture LED strip receptacle 102. This is comparable to the transverse channel LED strip receptacle 156 described with reference to FIG. 9. It carries a corresponding LED strip 160. This allows a circumferential illumination of the covered interior. To the longitudinal aperture LED strip receptacle 102 includes a longitudinal aperture holding portion 103. The longitudinal panel element 100 is attached along its longitudinal extension with its longitudinal panel-holding portion 103 on the longitudinal panel-holding projection 41 .1 of the longitudinal spar 40 and thereby held on the longitudinal beam 40. The corner connector 200 has a longitudinal leg 201 and the transverse leg 202 arranged at an angle thereto. The longitudinal leg 201 and the transverse leg

202 are integrally connected. The angle between the longitudinal leg 201 and the transverse leg 202 is presently 90 °. The corner connector 200 is made of a metal, in particular aluminum or steel.

In the longitudinal leg 201 and the transverse leg 202 are the threaded holes

203 introduced. In alignment with the threaded bores 203, cross-member mounting bores 86 are formed in the cross-member inner wall 82 and the longitudinal-member mounting bores 46 are formed in the longitudinal spar inner wall 42. The transverse bars 80 and the longitudinal bars 40 are screwed to the corner connector 200 with screws, not shown. Corner connectors 200 are arranged in the illustrated embodiment in all four corners of the frame 12 of the louvered roof 10. They allow a stable and resilient connection of the transverse and longitudinal bars 80, 40. The screws used are aligned to the covered interior and covered by the inwardly attached to the transverse and longitudinal members 80 components. For a viewer, this gives the impression of a screw-free construction.

The transverse bars 80 and the longitudinal bars 40 abut each other in the corner region of the frame 12. They are cut to miter. In the transverse spar inner wall 82 and the longitudinal spar inner wall 42 corner breakthroughs 12.1 are introduced along the abutting edge. These serve, as described for Figure 12, the implementation of mounting screws for attaching the frame 12 to the post 30th

The longitudinal struts 40 is placed with its longitudinal spar-supporting edge 44 on the first inner leg 30.1 of the post 30. As a result, the weight of the frame 12 with the slats 20 attached thereto can be well drained onto the post 30. FIG. 12 shows a perspective view of a diagonal section through the lamellar roof 10. The section is aligned along an angle bisector to a corner of the frame 12. Already introduced components and assemblies are designated and designed as described above.

The cut exposes the end region of the transverse gutter element 150. An inlet pipe 1 1 .2 connects the channel region of the transverse channel element 150 with an inlet connection of the downpipe 11. The rainwater introduced into the transverse gutter element 150 from the roof surface when the lamellar roof 10 is closed is discharged into the downpipe 11 via the inlet pipe 11.

The slats 20 are rotatably attached to the bearing angles 140 at the ends. Each lamella 20 is assigned a bearing angle 140 on both opposite sides. In the support legs 140.1 of the bearing bracket 140 described in FIG. 9, screw lead-throughs 140.3 are introduced. Through the screw bushings 140.3, the bearing angle 140 are connected by means not shown screws with the bearing angle-holding projection 88 of the cross member 80, as this is also shown in Figure 9.

The corner angle 200 is penetrated in a corner region 207 (see also FIG. 13) by stepped bores 204. The stepped holes 204 are aligned according to the bisector between the longitudinal leg 201 and the transverse leg 202 of the corner connector 200. They are aligned with the corner openings 12. 1, which are arranged along the joint of the cross-member inner wall 82 with the longitudinal spar inner wall 42 and the cross-member outer wall 83 with the longitudinal spar outer wall 43. In extension of the stepped holes 204 threaded blind holes 33 are inserted into the post 30. The threaded blind holes 33 are formed, starting from the formed between the inner legs 30.1, 30.2 corner in the post 30. They are thus guided by the corner reinforcement 30.5, as shown in FIG. Through the corner openings 12.1 and the stepped holes 204, not shown mounting screws can be screwed into the threaded blind holes 33. The mounting screws make their way with their screw heads to the steps of the stepped holes 204. Thus, a firm connection between a corner connector 200 and a post 30 can be made. The threaded blind holes 33 terminate within the post 30. Thus, the screwed mounting screws are not visible from the outside. Inwardly, the mounting screws are obscured by the longitudinal aperture element 100, the transverse channel element 150, the inlet element 190 and opposite the longitudinal channel element 90. Here, too, gives the viewer the impression of a screwless construction.

FIG. 13 shows a perspective view of a horizontal section through the lamellar roof 10. The section is laid in such a way that it is guided through the cable receptacles 26 of the lamellae 20 closed in the present case. Already introduced components are designated the same.

The connecting cables 57 are laid within the slats 20 each in a loop. Subsequently, the connecting cable 57 are guided in the cable receptacle 26 and through the bearing sleeve 142 in the cable channel 130. By laying the connecting cable 57 in a loop high tensile loads of the connecting cable 57 during assembly of the slats 20 and the interconnection of the photovoltaic module 50 are avoided. The connection cables 57 are designed to be highly flexible. They have bare or tin-plated class 5 or preferably class 6 copper souls in accordance with standard IEC 60228. The copper souls are insulated with a silicone rubber. In this case, a silicone mixture HD 22.1 - type E 12 is preferably used. Thus designed connecting cable 57 are designed to withstand frequent torsional loads, such as those that occur during pivoting of the slats 20, damage-free.

At the end of the sixth cavity 24.6 a slat outlet 24.8 is arranged. The slat drain 24.8 provides access to the water outlet spigot 27. End the blades 20 are completed by the rocker arms 1 17, 1 18. These seal at least the conclusion of the sixth cavity 24.6 waterproof.

The corner connector 200 is inserted into the hollow chambers 40.1, 80.1 of the longitudinal member 40 and the cross member 80. It has in each case an outer web 205 and an inner web 206. The inner webs 206 and the outer web 205 are aligned in the direction of the surface normal of the longitudinal spar inner wall 42 and the transverse spar inner wall 82. The threaded bores 203 are introduced into the inner webs 206 and the outer webs 205. They are aligned congruent with the longitudinal spar mounting holes 46 and the crossbar mounting holes 86. The corner connector 200 can thus be mechanically strong connected by appropriate screw with the crossbars 80 and the longitudinal members 40. In this case, a large proportion of the forces occurring on the custom-fit connector between the legs 201, 202 of the corner connector 200 and the hollow chambers 40.1, 80.1 of the longitudinal and transverse bars 40, 80 collected.

FIG. 14 shows an enlarged detail from FIG. 13 through a bearing region of a lamella 20. Identical components are designated as previously introduced. The bearing sleeve 140 is screwed through the ball bearing 141 and the long rocker arm 1 17 in the cable holder 26 of the body 21. The ball bearing 141 is fixed at its periphery in the bearing seat 140.4 of the bearing bracket 140. The ball bearing 141 and the rotary axis breakthrough 1 19 of the long rocker arm 1 17 are set radially blocked on the sleeve shoulder 142.4 of the bearing sleeve 142. The tool attachment 142.1 of the bearing sleeve 142 has a larger diameter than the inner diameter of the ball bearing 141. By the screwed into the cable holder 26 bearing sleeve 140 and its tool attachment 142.1 thus the long rocker arm 1 17 is pressed via the ball bearing 141 to the front side of the blade 20. A rotation of the long rocker arm 1 17 is transmitted to the blade 20. The connecting cable 57 is guided through the longitudinal bore 142.3 of the bearing sleeve 142 from the blade 20.

In the region of the sixth cavity 24.6 is along the end face of the inner lower side portion 23.4 and the subsequent inner partition 25.4 a Groove 1 17.4 in the base body 21 facing side of the long rocker arm 1 17 formed. In the groove 1 17.4 a seal is inserted. The sixth cavity 24.6 is thus sealed watertight end. The guided in the sixth cavity 24.6 rainwater can thus run off only via the slat outlet 24.8 from the sixth cavity 24.6.

FIG. 14 shows the terminal end of a lamella 20 with a long rocker arm 17 on one side of the lamellar roof 10, on which the adjusting mechanism of the lamellae 20 is arranged. The design is the same for lamellae 20 with short rocker arms 1 18, as shown in FIGS. 3 and 4, so that the illustration and description from FIG. 14 can also be applied to lamellas 20 with short rocker levers 1 18.

The opposite side of the louvered roof 10 is the same as the side shown in FIG. However, it is also conceivable to provide on the opposite side of the lamellar roof 10 no linear actuator 1 10, as shown in Figures 3 and 4. Also, then the linkages 1 15, 1 16, 1 16.1 be saved on the opposite side. The fins 20 may be on the opposite side of the front side by non-driven rocker arms 1 17, 1 18 completed. It is also conceivable to complete the slats 20 on the opposite side by end plates.

FIG. 15 shows a perspective sectional view of a view of a longitudinal member 40 in the region of the first lamella 20.1. Already introduced components are designated as previously introduced. The longitudinal beam 40 is according to the along the last lamella 20.2 extending longitudinal beams 40, we described it to the figures 8 and 1 1 executed. On the longitudinal spar a longitudinal aperture element 100 is arranged, as it is also shown in Figures 8 and 1 1. At the holding lug 47.1 of the longitudinal spar cover 47, the longitudinal trough element 90 is attached. Towards the covered interior, the longitudinal channel element 90 has a longitudinal channel aperture 91. The longitudinal trough panel 91 is arranged in the same plane as the front side of the adjacent longitudinal panel element 100 and connects directly to this. To the Longitudinal channel panel 91, a longitudinal channel bottom 92 is formed. The longitudinal gutter bottom 92 is guided to the upper longitudinal spar web 42.1 of the longitudinal spar 40. It is connected by means of the staples 170 shown in FIG. 8 and not shown here to the longitudinal spars 40. A longitudinal channel 96 forms the upper region of the longitudinal channel element 90 in the installed position. The longitudinal channel 96 is limited to the covered interior by a longitudinal trough outer wall 94 and opposite from a longitudinal trough inner wall 93. A channel bottom 97 closes the longitudinal channel 96 down. Upwards, the longitudinal channel 96 is opened. A rounded-out longitudinal channel sealing projection 95 closes the longitudinal channel outer wall 94 upwards. When the louvered roof 10 is closed, the sealing system 71 .2 of the lamellar seal 71 of the first lamella 20. 1 rests with its sealing surface 71. 3 on the longitudinal trough sealing lug 95. As a result, the longitudinal channel 96 is sealed off from the covered interior. Rainwater can drain from the roof surface into the longitudinal channel 96 of the longitudinal channel element 90. End side, the longitudinal channel 96 is not shown connected to the transverse channel element 150, so that the collected rainwater is passed to the downpipe 1 1. It is also conceivable to connect the longitudinal channel 96 directly to a drop tube 1 1.

FIG. 16 shows, in a schematic representation, the electrical connection of photovoltaic modules 50 of a plurality of fins 20. In the highly schematic and simplified, non-relevant depiction, the solar cells 53 of the photovoltaic module 50 are connected in series with cell connectors 52. From each photovoltaic module 50, a positive terminal 56.1 and a negative terminal 56.2 is led out. In the exemplary embodiment shown, two photovoltaic modules 50 are arranged per slat 20. The photovoltaic modules 50 of a lamella 20 are aligned so that in each case a positive terminal 56.1 facing a negative terminal 56.2 of the adjacent photovoltaic module 50. These opposing terminals 56.1, 56.2 are electrically connected together. The photovoltaic modules 50 of a blade 20 are thus connected in series.

The photovoltaic modules 50 of adjacent lamellae 20 are mutually aligned rotated by 180 °. Along the outer edges of the lamellar roof 10 thus alternate positive connections 56.1 and 56.2 negative connections of Photovoltaic modules 50 from. To the outer positive and negative terminals 56.1,

56.2 are connected according to positive and negative connection cables 57.2, 57.3. The negative connection cable 57.3 of the upper slat 20 in the illustration is connected by means of a PV connector 57.1 with the positive connection cable 57.2 of the subsequent second slat 20. Opposite, the negative connection cable 57.3 of the second lamella 20 is connected to a PV connector 57.1 with the positive connection cable 57.3 of the third lamella 20. The photovoltaic modules 50 of the adjacent lamellae 20 are thus electrically connected in series. This results in a meandering current flow. The last positive and negative connection cables 57.2,

57.3 of the series-connected photovoltaic modules 50 are connected as positive and negative inverter connections 57.4, 57.5 with an inverter, not shown. Preferably, one or more microinverters are provided.

Only so many photovoltaic modules 50 of adjacent lamellae 20 are connected in series that the system voltage is less than or equal to 60V. The system is therefore safe to touch, the risk of electric shock can be excluded. The risk of arcing is very low at voltages less than or equal to 60V. In case of fire, there is no danger due to high voltages during the extinguishing work.

To avoid the formation of so-called hot spots on, for example, a defective solar cell 53, each photovoltaic module 50 is associated with a bypass diode, not shown. However, it is also conceivable to assign several photovoltaic modules 50 of a lamella 20 to a bypass diode. In the case of a defective solar cell 53, the current can flow past the bypass diode, which is otherwise arranged in the reverse direction, on the relevant photovoltaic module 50 or the photovoltaic modules 50 of the lamellae 20 concerned. As a bypass diode, a Schottky diode is preferably provided. The bypass diode is preferably arranged in the notch 22.4 of the main body 21 of the lamella 20 shown in FIG. The bypass diode is protected by a glass fiber reinforced silicone protective cover. Likewise, soldered cables are insulated with such a glass fiber reinforced silicone protective cover. Also as connecting flags Running connections 57 have such a glass fiber reinforced silicone protective cover. The silicone protective cover is resistant to UV radiation and ozone. It has a wide temperature range from -60 ° C to +250 ° C. It is still waterproof.

In the schematized representation according to FIG. 16, only four solar cells 53 per photovoltaic module 50 are provided for a better overview. Preferably, however, a larger number of solar cells 53 are arranged in each photovoltaic module 50. For the production of photovoltaic modules suitable lengths of the series-connected cell strings arise when each photovoltaic module 50 eight, ten or twelve solar cells 53 are provided. However, photovoltaic module 50 with more than 12 solar cells 53 are also conceivable.

For the construction of a lamella 20, first the PV-bearing seals 70 and the lamellar seal 71 are fastened to the main body 21. The connection cables 57 are connected to the terminals 56 of the photovoltaic modules 20. Subsequently, the or the photovoltaic modules 50 are glued to the upper side 22.1 of the main body 21. The connection cables 57, as described above, are guided out of the main body 21 by the cable receiver 26. The ball bearings 141 with the bearing angles 140 and the respective rocker arms 1 17, 1 18 are placed on the sleeve lugs 142.4 of the bearing sleeves 142. In the grooves 1 17.4 of the rocker arms 1 17, 1 18 a seal is inserted in each case. From each side of the base body 21, a bearing sleeve 142 prepared in this way is then screwed with its thread 142.2 endwise into the cable receptacle 26 until the rocker arms 1 17, 1 18 bear against the respective base bodies 21. The water outlet nozzle 27 are connected to the water outlet 27.1 of the main body 21.

To build the slat roof 10, the posts 30 are fastened with their base plates 62 to the foundation screws 61 of the foundations 60. The transverse bars 80 are connected by means of the corner connectors 200 with the longitudinal bars 40 to form a frame 12. Subsequently, the pre-assembled lamellae 20 are attached to the opposite transverse bars 80. For this purpose, the arranged on both sides of the slats 20 bearing angle 140 with their support legs 140.1 the bearing angle retaining lugs 88 of the cross bars 80 placed and screwed with these. The rocker arms 1 17, 1 18, at least on one side of the slat roof 10, as described above, with the linkages 1 15, 1 16, 1 16.1 hinged together. Subsequently, the linear actuator 1 10 is mounted on the lower linkage 1 15 and the cross member 80. The connection cables 57 of the photovoltaic modules 50 are connected as described. The pre-assembled frame 12 with the slats 20 is placed on the post 30 and screwed to it. For this purpose, suitable mounting screws are guided through the stepped holes 204 of the corner connector 200 and screwed into the threaded blind holes 33 of the post 30. Subsequently, the longitudinal channel element 90, the longitudinal aperture elements 100, the cable channels 130, the cross-diaphragm elements 120, the transverse channel element 150, the LED strips 160 and the inlet element 190 are attached to the transverse and longitudinal bars 80, 40. At least along a post 30, a downpipe 1 1 is attached to the associated pipe holder 1 1 .1. The inlet pipe 1 1. 2 is mounted. The inverter terminals 57.4, 57.5 are connected to the inverter (s). Finally, the post covers 32 are fastened to the inner legs 30.1, 30.2 of the posts 30.
