Description

Die vorliegende Erfindung betrifft ein Beschattungssystem für ein Lichtband oder eine Lichtkuppel, mit zwei an gegenüberliegenden Seiten angeordneten Längsstreben, die mit einer Tragkonstruktion eines Lichtbandes oder einer Lichtkuppel verschraubbar sind.The present invention relates to a shading system for a light band or a dome light, with two arranged on opposite sides of longitudinal struts, which are screwed to a support structure of a light band or a dome light.

Es gibt einen Sonnenschutz für Lichtkuppeln, bei denen ein mit Lichtöffnungen versehenes gestanztes Blech pyramidenartig über eine Lichtkoppel montiert wird. Dabei werden einzelne dreieckförmige Platten über Befestigungselemente aneinander montiert und an einer Tragkonstruktion der Lichtkuppel festgelegt. Eine solche Konstruktion ermöglicht zwar einen notwendigen Abstand zwischen Lichtkuppel und Beschattungselement einzuhalten, allerdings ist die Montage relativ aufwendig, da eine Vielzahl von Einzelteilen befestigt werden muss. Zudem ist die Form der Pyramide für längliche Lichtbänder nur schlecht geeignet.There is a sunshade for skylights, in which a provided with light openings stamped sheet metal is mounted like a pyramid on a light coupling. In this case, individual triangular plates are mounted on each other via fasteners and fixed to a supporting structure of the dome light. Although such a construction allows to maintain a necessary distance between the light dome and shading element, however, the assembly is relatively expensive, since a large number of individual parts must be attached. In addition, the shape of the pyramid for elongated rooflights is poorly suited.

Für Lichtbänder gibt es auch Beschattungselemente, die bogenförmig über einen Lichtband gespannt werden. Diese Beschattungselemente sind aus einem Gewebe gebildet, das an einem Rahmen gespannt ist, der zur Verstärkung noch Mittelstreben aufweist siehe z.B. GB-A-2374095. Die Herstellung des Rahmens muss jeweils an die Größe des Lichtbandes angepasst werden, was relativ aufwendig und teuer ist. Zudem muss das aus Gewebe bestehende Material des Sonnenschutzes ringsum festgelegt werden und erreicht dann immer noch nicht eine besonders hohe Stabilität und ist nicht begehbar. Auch Schneelasten können die Stabilität des Gewebes beeinträchtigen. Zudem verschmutzt das gezeigte Gewebe relativ schnell, was ästhetisch als Nachteil empfunden wird.For light strips, there are also shading elements, which are stretched arcuately over a light band. These shading elements are formed of a fabric which is stretched on a frame which still has center struts for reinforcement see eg GB-A-2374095. The production of the frame must be in each case to the size of the light band be adapted, which is relatively expensive and expensive. In addition, the material made of tissue of the sunscreen must be set all around and then still does not reach a particularly high stability and is not accessible. Snow loads can also affect the stability of the fabric. In addition, the fabric shown contaminates relatively quickly, which is aesthetically perceived as a disadvantage.

Es ist daher Aufgabe der vorliegenden Erfindung ein Beschattungssystem für ein Lichtband oder eine Lichtkuppel zu schaffen, das einfach aufgebaut und montierbar ist und variabel für unterschiedlich große Überdachungsflächen einsetzbar ist. Ferner soll das Beschattungssystem eine lange Lebensdauer besitzen und eine Durchsturzsicherung bilden.It is therefore an object of the present invention to provide a shading system for a light band or a dome light, which is simple in construction and can be mounted and can be used variably for different sized roofing areas. Furthermore, the shading system should have a long life and form a fall protection.

Diese Aufgabe wird mit einem Beschattungssystem mit den Merkmalen des Anspruches 1 gelöst.This object is achieved with a shading system having the features of claim 1.

Erfindungsgemäß weist das Beschattungssystem zwei an gegenüberliegenden Seiten angeordnete Längsstreben auf, zwischen denen eine mit Lichtöffnungen versehene Platte aufgespannt ist und die Platte klemmend an den Längsstreben festgelegt ist. Dadurch ist das Beschattungssystem aus einer minimalen Anzahl an Bauteilen aufgebaut und leicht zu montieren. Ferner lässt sich die Größe der als Sonnenschutz vorgesehenen Platte in weiten Bereichen variieren, weshalb sich dieses Beschattungssystem für Lichtbänder, Lichtkuppeln und andere lichtdurchdringende Bauelemente unterschiedlicher Größe eignet. Mit denselben Befestigungsteilen können dann unterschiedlich große Dachflächen überdeckt werden.According to the invention, the shading system has two longitudinal struts arranged on opposite sides, between which a plate provided with light apertures is clamped and the plate is clamped to the longitudinal struts. As a result, the shading system is constructed from a minimum number of components and easy to assemble. Furthermore, the size of the plate provided as a sunshade can be varied within wide ranges, which is why this shading system is suitable for light strips, skylights and other light-penetrating components of different sizes. With the same fastening parts then different sized roof areas can be covered.

Gemäß einer bevorzugten Ausführungsform der Erfindung ist die Platte randseitig jeweils in einer Aufnahme zwischen einer Leiste und einer Längsstrebe gehalten. Dadurch lassen sich leicht Toleranzen ausgleichen, da die Platte innerhalb der Aufnahme gehalten ist und es nicht auffällt, wenn sich die Platte etwas weiter in die Aufnahme hinein oder nur kurz in die Aufnahme hinein erstreckt. Um eine besonders große Breite für den Toleranzausgleich zu besitzen, erstreckt sich die Leiste vorzugsweise etwa über die Breite der Längsstrebe, da in diesem Bereich dann ein Spalt für das Einfügen der Platte ausgebildet ist. Die Leiste kann beispielsweise als Winkelprofil ausgebildet sein, das mit einem Schenkel die Platte randseitig überdeckt und mit einem zweiten Schenkel die Längsstrebe teilweise verdeckt. Dadurch ergibt sich auch optisch ein geschlossenes Erscheinungsbild und eine randseitig scharfe Kante der Platte wird vollständig überdeckt und bietet kein Verletzungsrisiko.According to a preferred embodiment of the invention, the plate is held at the edge each in a receptacle between a bar and a longitudinal strut. This makes it easy to compensate for tolerances, since the plate is held within the receptacle and it is not noticeable when the plate extends slightly further into the receptacle or only briefly into the receptacle. In order to have a particularly large width for tolerance compensation, the strip preferably extends approximately over the width of the longitudinal strut, since in this area then a gap for inserting the plate is formed. The strip may for example be formed as an angle profile, the edge of the plate covered with a leg and partially covered with a second leg, the longitudinal strut. Thereby also results visually a closed appearance and a sharp edge edge of the plate is completely covered and offers no risk of injury.

Erfindungsgemäß sind zwischen den seitlichen Längsstreben ein oder mehrere parallel zu den Längsstreben angeordnete Mittelstreben zur Abstützung der Platte montiert. Dadurch können auch Lichtbänder mit erheblicher Breite mit einem erfindungsgemäßen Beschattungssystem ausgerüstet werden. Die Mittelstreben dienen zur Abstützung der Platte, sodass auch größere Gewichtslasten aufgenommen werden können und das Beschattungssystem gleichzeitig eine nach Norm zugelassene Durchsturzsicherung bildet.According to the invention one or more parallel to the longitudinal struts arranged center struts for supporting the plate are mounted between the lateral longitudinal struts. As a result, it is also possible to equip strip lights of considerable width with a shading system according to the invention. The center struts serve to support the plate, so that even larger weight loads can be absorbed and the shading system simultaneously forms a standard approved fall-through protection.

Vorzugsweise ist die Platte auf der oder den Mittelstreben nur lose aufgelegt. Gerade bei starker Sonneneinstrahlung dehnt sich die Platte aus und könnte Spannungen in der Platte und der Tragkonstruktion verursachen. Wenn die Platte nur lose auf die Mittelstreben aufgelegt ist, kann diese sich bei starker Erhitzung nach oben wölben und von den Mittelstreben abheben, ohne das Wärmespannungen das Material beanspruchen und auf die Tragkonstruktion abgeführt werden müssen. Alternativ kann in eine der Mittelstreben zusätzlich noch eine Verschraubung vorgesehen sein.Preferably, the plate is placed on the or the center struts only loosely. Especially in strong sunlight, the plate expands and could cause tension in the plate and the supporting structure. If the plate is placed only loosely on the center struts, this can bulge upwards when strongly heated and stand out from the center struts, without the thermal stresses stress the material and must be dissipated to the support structure. Alternatively, a screw connection can additionally be provided in one of the center struts.

Für eine leichte Konstruktion des Beschattungssystems sind die Längsstreben und/oder die Mittelstreben als Hohlprofile ausgebildet, die einerseits für einen ausreichenden Abstand zwischen Lichtkuppel oder Lichtband und der Platte sorgen und andererseits nur ein geringes Eigengewicht besitzen. Die Längsstreben und/oder die Mittelstreben weisen vorzugsweise eine nach oben schräg verlaufende Stirnseite auf und eine an einer Tragkonstruktion anliegende Wand der Längsstrebe und/oder der Mittelstrebe ist von oben her zugänglich. Dadurch lässt sich die Längsstrebe und/oder die Mittelstrebe auf einfache Weise verschrauben, da die bodenseitig angeordnete Wand des Hohlprofils für das Verschrauben zugänglich ist. Für eine Abdichtung können dann die Stirnseiten der Längsstreben und/oder Mittelstreben mit einer Abdeckung verschlossen sein.For a lightweight construction of the shading system, the longitudinal struts and / or the center struts are formed as hollow profiles, on the one hand provide a sufficient distance between the dome or light band and the plate and on the other hand have only a low weight. The longitudinal struts and / or the center struts preferably have an upwardly inclined end face and a voltage applied to a support wall wall of the longitudinal strut and / or the center strut is accessible from above. As a result, the longitudinal strut and / or the center strut can be screwed in a simple manner, since the bottom side arranged wall of the hollow profile is accessible for screwing. For sealing, the end faces of the longitudinal struts and / or center struts can then be closed with a cover.

Für eine besonders stabile Befestigung des Beschattungssystems sind die Längsstreben und/oder die Mittelstreben mit Querstreben der Tragkonstruktion des Lichtbandes oder der Lichtkuppel verschraubt. Die meisten Lichtbänder weisen in regelmäßigen Abständen Querstreben auf, damit dazwischen die transparenten Sichtelemente eingebaut werden können. Diese Querstreben können dann gleichzeitig für das Beschattungssystem verwendet werden, um eine sichere Stützkonstruktion auch bei großen Breiten zu gewährleisten.For a particularly stable attachment of the shading system, the longitudinal struts and / or the center struts are bolted to cross members of the supporting structure of the light band or the dome light. Most light bands have at regular intervals cross struts, so that between the transparent viewing elements can be installed. These cross struts can then be used simultaneously for the shading system to ensure a secure support structure, even at large widths.

Um das Beschattungssystem auch als Durchsturzsicherung nutzen zu können und einen Hagelschutz zu geben, besteht die Platte aus Metall. Metall lässt sich zudem leicht reinigen und besitzt eine lange Lebensdauer. Ferner bildet das Beschattungssystem eine harte Bedachung und besitzt eine Mehrfachfunktion, wie eine Einbruchhemmung.In order to be able to use the shading system also as a fall-through protection and to give a hail protection, the plate consists of metal. Metal is also easy to clean and has a long life. Furthermore, the shading system forms a hard roof and has a multiple function, such as burglar resistance.

Ein Beschattungssystem 1 ist an einem Lichtband 2 montiert, dass in Draufsicht rechteckförmig ausgebildet ist und an einem Dach eines Gebäudes montierbar ist.A shading system 1 is mounted on a light band 2, which is rectangular in plan view and can be mounted on a roof of a building.

Das Beschattungssystem 1 umfasst an gegenüberliegenden Seiten des Lichtbandes 2 angeordnete Längsstreben 3, die als Hohlprofil aus Metall, beispielsweise Aluminium ausgebildet sind. Die Längsstreben 3 sind mit einer Tragkonstruktion 4 des Lichtbandes 2 verschraubt. Zwischen den beiden Längsstreben 3 sind in regelmäßigen Abständen angeordnete Mittelstreben 8 ebenfalls an der Tragkonstruktion 4 festgelegt. Die Tragkonstruktion 4 des Lichtbandes 2 ist an einem Aufsatz 5 montiert, der abgedichtet an einem Gebäudedach festlegbar ist.The shading system 1 comprises arranged on opposite sides of the light band 2 longitudinal struts 3, which are formed as a hollow profile made of metal, for example aluminum. The longitudinal struts 3 are bolted to a support structure 4 of the light strip 2. Between the two longitudinal struts 3 arranged at regular intervals center struts 8 are also fixed to the support structure 4. The supporting structure 4 of the light strip 2 is mounted on an attachment 5 which is sealed to a building roof can be fixed.

Auf den Längsstreben 3 und den Mittelstreben 8 ist eine Platte 6 aufgespannt, in der Lichtöffnungen 11 ausgespart sind. Die Platte 6 besteht aus einem Metallblech mit einer Stärke zwischen 1 und 5 mm, vorzugsweise etwa 2 mm und weist Lichtöffnungen 11 auf, die ein regelmäßiges Muster einnehmen. Die Lichtöffnungen 11 nehmen im Verhältnis zur Grundfläche der Platte 6 etwa eine Fläche von 20 bis 70% vorzugsweise 35 bis 45% ein.On the longitudinal struts 3 and the center struts 8, a plate 6 is spanned in the light openings 11 are recessed. The plate 6 consists of a metal sheet with a thickness between 1 and 5 mm, preferably about 2 mm and has light openings 11, which occupy a regular pattern. The light openings 11 take in relation to the base surface of the plate 6 about an area of 20 to 70%, preferably 35 to 45%.

An den Längsstreben 3 ist die Platte 6 in einer Aufnahme gehalten, die aus einer Leiste 7 und der darunter angeordneten Längsstrebe 3 gebildet sind, wobei die Platte 6 in dem Zwischenraum aufgenommen ist.On the longitudinal struts 3, the plate 6 is held in a receptacle formed of a strip 7 and the underlying longitudinal strut 3, wherein the plate 6 is received in the intermediate space.

Die Leiste 7 ist L-förmig ausgebildet, wobei ein Schenkel des L etwa die Breite der Längsstrebe 3 besitzt und die Platte 6 klemmend festlegt und der zweite Schenkel an der Seitenfläche der Längsstrebe 3 anliegt und mit dieser verschraubt ist. Zum Festlegen der Platte 6 wird der obere Schenkel der Leiste 7 ebenfalls verschraubt, wobei die Schraube die Leiste 7, die Platte 6 und die Längsstrebe 3 durchgreift. Durch die Breite des Schenkels der Leiste 7 kann die Platte 6 mit einem gewissen Spiel in der Aufnahme zwischen Leiste 7 und Längsstrebe 3 gehalten sein, sodass wegen eines möglichen Toleranzausgleiches die Montage vereinfacht wird. In Figur 3 ist schematisch die Befestigung mittels Schrauben 13 und 14 dargestellt.The strip 7 is L-shaped, wherein a leg of the L has approximately the width of the longitudinal strut 3 and the plate 6 defines by clamping and the second leg rests against the side surface of the longitudinal strut 3 and is screwed thereto. To set the plate 6, the upper leg of the bar 7 is also screwed, the screw, the bar 7, the plate 6 and the longitudinal strut 3 passes through. Due to the width of the leg of the bar 7, the plate 6 can be held with a certain play in the recording between bar 7 and longitudinal strut 3, so because of a possible tolerance compensation, the assembly is simplified. In Figure 3, the attachment by means of screws 13 and 14 is shown schematically.

Zur Befestigung der Längsstreben 3 und der Mittelstreben 8 sind Schrauben 15 durch eine Bodenwand der als Hohlprofil ausgebildeten Längsstrebe 3 und Querstrebe 8 durchgeführt, die mit einer Querstrebe 12 der Tragkonstruktion 4 des Lichtbandes 2 verschraubt sind. Dabei ist eine Stirnseite 9 der Längsstrebe 3 und Mittelstrebe 8 schräg ausgebildet, sodass die randseitig angeordnete Schraube 15 von oben her zugänglich ist. Die Stirnseite 9 der Längsstreben 3 und Mittelstreben 8 kann dann durch eine Abdeckung dicht verschlossen werden. Die Platte 6 liegt auf den Mittelstreben 8 nur lose auf und kann sich bei entsprechender Erhitzung daher wölben, damit keine Wärmespannungen auf die Tragkonstruktion 4 abgeleitet werden müssen.For fastening the longitudinal struts 3 and the center struts 8 screws 15 are performed by a bottom wall of the formed as a hollow profile longitudinal strut 3 and cross strut 8, which are bolted to a transverse strut 12 of the support structure 4 of the light strip 2. In this case, an end face 9 of the longitudinal strut 3 and center strut 8 is formed obliquely, so that the edge arranged screw 15 is accessible from above. The front side 9 of the longitudinal struts 3 and center struts 8 can then be sealed by a cover. The plate 6 rests on the center struts 8 only loosely and can therefore buckle with appropriate heating, so that no thermal stresses on the support structure 4 must be derived.

In Figur 5 ist ein weiteres Ausführungsbeispiel gezeigt, bei dem die Platte 6 statt gewölbt flach auf zwei Längsstreben 3 und einer Mittelstrebe 8 montiert ist. Die Längsstreben 3 und die Mittelstreben 8 können auf einer Tragkonstruktion 4 in der vorher gezeigten Weise befestigt werden. Auch bei dieser Ausführungsform ist die Platte 6 in einer Aufnahme zwischen der Leiste 7 und den Längsstreben 3 befestigt.In Figure 5, a further embodiment is shown, in which the plate 6 instead of curved flat on two longitudinal struts 3 and a center strut 8 is mounted. The longitudinal struts 3 and the center struts 8 can be mounted on a support structure 4 in the manner previously shown. Also in this embodiment, the plate 6 is mounted in a receptacle between the bar 7 and the longitudinal struts 3.

In Figur 6 ist eine weitere Ausführungsform gezeigt, bei der die Platte 6 geknickt ausgebildet ist. Die Platte 6 ist ansonsten in der vorgenannten Weise über eine streifenförmig ausgebildete Leiste 7 und Schrauben 13 an Längsstreben 3 festgelegt.FIG. 6 shows a further embodiment in which the plate 6 is formed bent. The plate 6 is otherwise fixed in the aforementioned manner via a strip-shaped bar 7 and screws 13 on longitudinal struts 3.

In Figur 7 ist das rautenförmige Muster der Lichtöffnungen 11 in der Platte 6 im Detail gezeigt. Die Lichtöffnungen 11 sind durch mehrere ausgestanzte Quadrate 61 gebildet, zwischen denen Stege 62 angeordnet sind. Dadurch kann nur ein Teil des auftreffenden Lichtes zu dem darunter liegenden Lichtband bzw. Lichtkuppel gelangen. Abwechselnd zu den Lichtöffnungen 11 sind durchgehende Flächen 60 aus Metall vorgesehen.In FIG. 7, the diamond-shaped pattern of the light openings 11 in the plate 6 is shown in detail. The light openings 11 are formed by a plurality of punched-out squares 61, between which webs 62 are arranged. As a result, only a part of the incident light can reach the underlying light band or dome light. Alternating to the light openings 11, continuous surfaces 60 of metal are provided.

In Fig. 8 ist eine modifizierte Ausführungsform eines Beschattungssystems gezeigt, bei dem an einer Mittelstrebe 8 eine Dichtung 20 montiert ist. Die Dichtung 20 ist plattenförmig ausgebildet und überdeckt die Stirnkante der Mittelstrebe 8, wobei an der Dichtung 20 ein Schlitz 21 ausgebildet ist, in den die Platte 6 eingefügt ist. An einem gegenüberliegenden Ende 22 liegt die Dichtung 20 lose auf einem Profil 23 auf, so das Flüssigkeit an der schräg angeordneten Dichtung 20 abströmen kann. Ferner übernimmt die Dichtung 20 die Funktion von Schallschutz und kann für eine gewisse Kompensation bei einer Wärmeausdehnung der Bauteile sorgen. Die Dichtung 20 kann dabei zwischen den Tragprofilen durchgängig aufgespannt sein.FIG. 8 shows a modified embodiment of a shading system in which a seal 20 is mounted on a center bar 8. The seal 20 is plate-shaped and covers the end edge of the center strut 8, wherein on the seal 20, a slot 21 is formed, in which the plate 6 is inserted. At an opposite end 22, the seal 20 loosely rests on a profile 23 so that liquid can flow off at the obliquely arranged seal 20. Furthermore, the seal 20 performs the function of sound insulation and can provide for a certain compensation in a thermal expansion of the components. The seal 20 can be stretched consistently between the support profiles.

Die gezeigte Erfindung ist nicht auf die dargestellten Ausführungsbeispiele beschränkt. Die Form der Platte 6 kann sowohl in der Breite als auch hinsichtlich der Aussparungen 11 frei gewählt werden. Vorzugsweise wird die Breite der Platte 6 so bemessen sein, dass sie von einer Rolle abgewickelt werden kann und nur in der gewünschten Länge abgetrennt werden muss.The illustrated invention is not limited to the illustrated embodiments. The shape of the plate 6 can be freely selected both in width and in terms of the recesses 11. Preferably, the width of the plate 6 will be sized so that it can be unwound from a roll and must be separated only in the desired length.

Ferner ist es möglich, die Längsstreben 3 und die Mittelstreben 8 und 9 nicht direkt an einer Tragkonstruktion festzulegen, sondern für die Montage Winkelprofile einzusetzen. Der Einsatz von Winkelprofilen hat den Vorteil, dass diese bei einfacher Fertigung die Montage erleichtern und insbesondere die Längsstreben 3 und Mittelstreben 8 und 9 seitlich in einem mittleren Bereich verschraubt werden können. Ferner können die Winkel an der Tragkonstruktion oder den Längsstreben 3 oder Mittelstreben 8 und 9 vormontiert werden.Furthermore, it is possible not to define the longitudinal struts 3 and the center struts 8 and 9 directly on a supporting structure, but to use angle profiles for the assembly. The use of angle profiles has the advantage that they facilitate assembly with simple production and in particular the longitudinal struts 3 and center struts 8 and 9 can be screwed laterally in a central region. Furthermore, the angles can be pre-assembled on the support structure or the longitudinal struts 3 or center struts 8 and 9.
