Roofing with at least one movable roof part "

The invention relates to a canopy, preferably as a kit, with at least one movable roof part, consisting of? two parallel metallic longitudinal girders with a rectangular cross-section and at least one metallic inner frame, which can be displaced between the longitudinal girders by means of rollers on opposite running rails, encompassing a maximum of about half the roof area with inserted plates, as well as a supporting structure that forms the rest of the roof area with also inserted plates, with one running rail L -shaped and attached to the vertical inner wall surface of a longitudinal beam and the at least one inner frame is placed on carriage holders to which the rollers are attached and a U-shaped drainage channel is attached to one of the longitudinal beams.

Such canopies are known for winter gardens, courtyards, restaurants, etc. (DE-OS 33 08 285). The two longitudinal beams are parts of a circumferential outer frame which has a rectangular upright cross-section and rests in a horizontal position on a substructure. At least one inner frame that can be moved on rollers is arranged within this outer frame, the longitudinal axes of the frame profiles likewise lying in a horizontal plane. In this inner frame, the panels are set with a gradient, and the purpose of the frame construction is to make the gradient invisible from the outside. In spite of the limited profile height, this is quite possible with conventional sliding roofs, because the gradient is a maximum of around 5 % . Nevertheless, the frame construction shields a considerable part of the incident light, which was previously perceived as pleasant.

So-called solar extensions have recently been used propagated for residential buildings that have the task of capturing as much of the solar energy as possible and to pass it on to the interior of the immediately adjacent residential building. The effect of such "Passive system" is despite the fact that no technical devices such as solar collectors and heat pumps are used very remarkable: the heating season is shortened in winter, and on many days in spring and autumn Artificial heating of the house can be completely dispensed with.

However, an effective solar cultivation requires a larger pitched roof, which can be 30 % and more, with shading effects being largely avoided by the supporting structure, which usually consists of light metal profiles. This in turn leads to an undesirably high temperature load on hot summer days, so that sufficient ventilation of the solar cultivation must be ensured. Just think of the intense heating of motor vehicles, which leads to unbearable temperature loads, especially due to the extremely sloping windshields and rear windows. While the airflow quickly provides cooling in vehicles, this is naturally not possible with solar add-ons.

Another problem is the need for roof drainage. While on the one hand the large sloping roof keeps the static load from snow within limits, the relatively large gradient creates high Flow velocities, so that the rainwater easily splashes out over insufficiently dimensioned drainage channels. A run down of rainwater on the vertical glass surfaces of the solar add-ons is highly undesirable, so that one to Avoiding this disadvantage, a so-called "controlled drainage" through adequately dimensioned drainage channels must provide.

Solar attachments with a controlled system are known Drainage and a ventilation option through hinged skylights. However, these only give Openings of relatively small cross-section free, so that their effect in strong sunlight

is limited. ;

It is also known _{9 to provide} the roofs of solar add-ons with a sliding element which, however, can be moved in the direction of the slope. This has the disadvantage that the actuation is considerably influenced by gravity, which is particularly noticeable because of the large pitch of the roof.

The invention is therefore based on the object of specifying construction instructions for solar add-ons despite the large sloping roof and controlled drainage a movability of roof parts transversely to the slope direction is possible without high profiles are required that obstruct the sun's rays.

In the case of the roofing described at the beginning, the object is achieved according to the invention in that that

s) the side members are attached at different heights are,

b) the one L-shaped running rail is attached to the upper side rail, and

c) at the lower longitudinal beam to this the U-shaped drainage channel is attached para7 7E7, in the

d) support bridges are used in a form-fitting manner and at intervals, at least on the top of each two grooves are arranged with at least one inserted running rail and one inserted support rail.

- or similar. A preferred type of panels
-. £ _ ~ 7_- represents what is known as the plastic bar glass, in which two plane-parallel plates are connected to one another by a large number of parallel bars. These plates are permeable to solar radiation, but prevent to a considerable extent the heat dissipation to the outside by convection
and conduction could occur. Such panels can even be walked on, making them an ideal material for solar add-ons.

s ("' With the solution according to the invention, it is possible, despite the large roof pitch, within the longitudinal beams
to arrange two or even more movable inner frames with the aforementioned inserted plates and in
horizontal direction, ie parallel to the longitudinal beams, to move under or over one another. It is then only necessary to divide the entire roof area into a corresponding number of equally sized fields

subdivide, usually one of these fields is fixed, while the other fields are movable and with the fixed field for

Coverage can be brought. In this way, a very large opening can be opened in the roof of the solar extension. üftun & szweck ^ n ^ are formed. It is also possible to make all fields movable, so that then d - s Faket above the other pushed fields can be brought into a beifrbige position _s so that the exposed üffnung can also be located at any desired point, or it is both sides of the For example, in the middle, stacked fields, each formed an opening.

By attaching the side members at different heights, the large roof pitch described made possible without the incidence of light being excessively obstructed would. It will still be shown that some of the profiles of the inner frame to a certain extent is in the shadow of the outer side member, so that these profile parts at least no additional Throw shadows on the translucent panels.

By attaching the running rails parallel to the horizontally running longitudinal girders, it can be moved of the movable roof parts unaffected by d <= r gravity, so that the same speeds in both directions of movement without special braking measures

Can be 3 and 4 m, so that the inner frame with the panels used a considerable weight exhibit.

Finally, through the structural union of the U-shaped drainage channels and the spaced in these supporting bridges a good controlled drainage is possible without rainwater runs down over the panes of the substructure.

Finally, the structurally coordinated parts also allow easy assembly at the place of installation, where appropriate, additional adaptation measures are also possible.

It is particularly advantageous if the supporting bridges (based on their installation position) have one on both sides have vertical flange and a web connecting these and if the top of this web the has at least two grooves with a widening groove base »so that the rails and the Support rail can be inserted with a form-fitting connection.

In connection with the measure that the height and the distance of the outer surfaces of the flanges of the supporting bridge Corresponding to the clear inside dimensions of the drainage channel, the drainage channel becomes the supporting bridges and the running or support rails formed a compact but dimensionally stable composite of the parts mentioned, the can easily be attached to or on the associated longitudinal member and in use a perfect, i.e.

In Figure 1 is a canopy 1 for a solar cultivation shown, which consists of an upper box-shaped longitudinal member 2 and a parallel thereto there is lower longitudinal member 3, between which there is a movable roof part 4 and a fixed roof! 5 are located. The direction of displacement runs perpendicular to the plane of the drawing and parallel to the longitudinal axes the girders 2 and 3, of which the longitudinal girders 3 are also formed by a box-shaped profile will. It goes without saying that in the case of canopies that have a greater length in the direction of displacement, the arrangement can also be made several times in a row.

The sliding roof part 4 consists of a metallic one Innenrahmfcn 6, which is on three circumferential sides of a Plate 7 extends from web glass. At the lowest point, the inner frame 6 is used for water drainage closed by a further profile, not shown. The plate 7 is in the inner frame 6 by so-called Glazing strips 8 held, which are designed as a hollow profile and inserted into the inner frame 6 in a form-fitting manner.

The roof part 5 forms a stationary support structure, which consists of a further inner frame 9 with an identical Profile cross-section consists in which a plate 10 is medium-identical Glazing strips 8 is used. The inner frame 9 is also for drainage purposes on the deepest point closed by a profile, not shown, which does not have the drainage surface 10a of Plate 10 protrudes.

The upper side rail 2 is attached to a wall 11 of a building and has a vertical inner wall surface 2a, on which an L-shaped running rail 12 and a support rail 13 with an identical profile cross-section are attached in the Heise that the longer legs of the profiles point upwards. Details -_ of the profile cross-section are shown below using the Figure 8 explained in more detail.

At the upper end of the inner frame 6 _S, more precisely, on its profile parallel to the direction of displacement, there are several carriage holders 18, of which only the foremost one is visible in FIG. Details of the profile emerge from FIG. In each carriage holder there are two rollers 15 which are connected to one another by a rocker to form a carriage. This carriage is articulated in its center with the carriage holder, which in turn is firmly screwed to the inner frame 6. At its apex, the carriage holder has an anti-lift device 14a, which prevents the rollers 15 from moving away from the running rail 12 in an inadmissible manner.

In an analogous manner, the stationary inner frame 9 has a support bracket 16, the details of which are shown in FIG are. This bracket has a bracket 16a, which by means of a section from a cylindrical

Contact surface rests on the mounting rail 13 so that a flat support regardless of the slope or the roof slope is guaranteed.

It can be seen that due to the chosen arrangement only -5 a relatively small height of the longitudinal member is required, and that the fastening means described above are nevertheless within the projection surface this side member are located. The upward gap between the roof parts 4 and and the longitudinal beam 2 is covered by a weather bar profile 17, which at its free end a Has insertion groove 1 / a for a sealing profile, not shown. Audi the weather bar profile is on attached to the longitudinal beam 2.

At the far end has the movable inner frame a corresponding number of carriage holders 18, in which pairs of rollers 15 are also inserted are. These rollers can be moved on a running rail, the details of which are explained in more detail in FIG will. The other end of the fixed roof part 5 is provided with several support brackets 20, of which only the foremost is visible here, too. Each of these support brackets has a boom 20a, the is bent at the side so that it overlaps the head of a mounting rail 21 with a partial cylindrical surface, on their profile cross-section in connection with figure will be discussed in more detail. In any case, it can be seen from the figure that the different heights of

Running rail 19 and support rail 21 in connection with the fastening of the rollers 15 on the roof part 4 or the support bracket 20 on the fixed roof part 5 has a height graduation or an overlap of the roof parts 4 and 5 The tightest space is possible, while at the same time with respect to the lower longitudinal member 3, a gap 22 of ! Sufficient width is maintained to allow the rainwater to enter.

It goes without saying that the position of the displaceable to the stationary roof part can also be exchanged, with Adjustment measures at the support points of the roof parts must be made.

Running rail VJ and support rail 21 are suspended from the lower longitudinal member 3 as follows: A plurality of supporting bridges 23 are screwed to the longitudinal member 3 at intervals and consist of short sections of a profile that will be explained in more detail with reference to FIG. These supporting bridges have on both sides a vertical flange 24 and 25 and a connecting web 26, in the top of which there are three grooves 27, 28 and 29, which have a widening groove base, so that the insertion of a component with a complementary dovetail 30 or 31 is possible (Figures 4 and 5). The FT3πsch 24, which points to 3uBeπ in relation to the roofing, has an extension 24a which protrudes beyond the grooves in the web 26 and with which the support bridge 23 can be attached to the lower longitudinal member 3, for example by screwing.

stiffening of the side member 3 is arranged in this a U-shaped stiffening ps-ofil ^ ^c .

According to FIG. 1, the supporting bridge? 'I are at the same time the: _--. "- brackets for a U-shaped drainage channel 33, the details of which are explained in more detail using the profile cross-section in FIG. 6. The drainage channel 33 has at the upper edges their legs and 35 each have a nose 36 and 37 which overlaps the respective associated flange 24 or 25 of the support bridge 23. The representations in Figures 3 and 6 can be seen in direct alignment, ie the nose 36 - engages in a recess 24b in the flange 24 ₅ and the nose 37 overlaps the complementary beveled upper edge 25a of the flange 25. The heights H, and H2 as well as the distance D of the outer surfaces 24c and 25c of the flanges are designed so that they correspond to the corresponding internal dimensions of the drainage channel 33 (Figure 1)

^ the drainage channel 33 according to Figure 6 at its i; inner Leg 35 at its upper edge has a receiving groove 38 for inserting a sealing strip, not shown.

From Figures 4 and 5 it can be seen that the Laufbzw. Support rails 19 and 21 a rail head 39 biw. 40 have, which represents the largest part of a circumference in cross section. Towards the bottom, a trapezoidal widening web 41 or 42 connects to the rail head, which is finally in a swallow

tail 30 or 31 ends. By means of these dovetail tails, the rails are partially in the grooves 27 to 29 in the support bridge 23 can be inserted. The plurality of grooves in the support bridge 23 is one great flexibility with regard to structural adaptations given.

Figure 1 shows that the overall arrangement of supporting bridges 23, drainage channel 33 and Laufbzw. Support rails 19 and 21 for the roof parts represent a floating storage, the ^ tirch the selected Arrangement is extremely compact, but still mechanically dimensionally stable.

In Figure 2, the same parts as before are provided with the same reference numerals, but the details easier to see because of the larger scale. In contrast to Figure 1, however, the drainage channel is here 33 not overhung on a vertical side wall of the lower longitudinal member 3, but placed on its upper horizontal surface.

In this case, the drainage channel 3 has a supporting function due to its lateral overhang L, ie the supporting bridges 23 are supported with the lower edges of their flanges 24 and 25 on the bottom of the drainage channel. The extension 24a in FIG. 1 is no longer present here. Rather, a guide profile 43 is placed on the top of the flange 24 and the upper edge of the leg 34 of the drainage channel 33, which one with the

Leg 34 represents a flush screen and delimits the gap 22 to the outside. It can be seen that the supporting bridges 23 have a wider groove in the vicinity of their outer flange 24 for this purpose have a nose 44 a, which is used to define the guide profile 43. It can also be seen that the supporting bridges 23 in the vicinity of their flange 25 have a further groove 45 into which a on the inner frame attached sealing profile 46 protrudes, which engages over the inner leg 35 of the drainage channel and on this brings about a reliable splash guard or seal.

In Figure 7, a carriage holder 14 is shown, which consists of a profile section. The cross-section consists essentially of an approximately isosceles L-shaped basic profile, one of the legs 14c is supplemented by an angled extension 14d to form an outwardly pointing "U". In the crown an anti-lift device 14a is attached, which is formed by a projection that both to the other Leg 14e as well as to the yoke 14f of the angular Process runs. In the space formed between the angular extension i-nd the leg 14c a carriage 47, which is shown in FIG. 8, is accommodated and interlaced. The parts 7 and 8 are shown in an exploded view.

- 21 -

In Figure 8, an L-shaped running rail 12 is shown, which has a long leg 12a and a has short legs 12b. A rail head 12b is arranged on the top of the short leg, which is also designed as a cylindrical surface on most of its circumference. The carriage 47 can be moved on this rail head by means of its rollers 15. The castors are mounted in pairs in a rocker 48, which can be pivoted relative to a fastening body 49 is, so that both rollers 15 always come to rest with the same contact pressure.

It goes without saying that the circumferential groove of the rollers is complementary to the rail head 12c.

In Figure 9, a support bracket 16 is shown, which is also formed by a substantially rectangular angle profile is formed with the legs 16c and 16d. In the area of the vertex there is also one here Anti-lift device 16b, which runs parallel to the leg 16c. A bracket 16a is attached to the leg 16d, which has a bearing surface 16e which is circular in cross section. Between the anti-lift device 16b and the rail head (12c) of the L-shaped support rail 13 engages the bracket 16a. This mounting rail is identical in cross section to the running rail 12 according to FIG. 8. The interaction is shown in FIG. 1 emerged.

In Figure 10, a support bracket 20 is shown, which is also in its essential part by a right-angled Profile is formed with the legs 20b and 20c. Located in the vertex of this profile the already described boom 20a, which likewise has a bearing surface with a circular cross-section 2Od owns. The longitudinal axis of the boom 20a runs approximately in the direction of the bisector, so that the bearing surface 20d extends offset to both legs 20b and 20c.

With reference to FIG. 1, it emerges that with regard to the rail heads which are circular in cross section on the one hand and with regard to the formation of the rollers 15 and the bearing surfaces in the support brackets on the other hand, an inclination of the roof that can be varied within wide limits is possible.

Figure 11 shows a very schematic representation Part of a solar cultivation with the invention Roofing 1. The longitudinal beams extending in the longitudinal direction of the extension can be clearly seen 2 and 3 and their course at different heights. Can also be clearly seen also the considerable sloping roof ?. The direction of movement of the movable roof part 4 is through a Marked with double arrow. The lower longitudinal member 3 rests on a substructure 49, which is not explained in more detail. which is also made of metal profiles with inserted Plates 50 is made.

The profiles described above are all profiles produced by extrusion made of a light metal alloy, as it is often used in metal construction. Usually the profiles are anodized. The drainage channel is connected to a drain pipe, not shown.
