Definitions
- the present invention relates to a sunblind with a slat frame comprising opposite, extending over the length of the sunblind profiles and these interconnecting cross struts, and attached to the slat frame cover layer.
- Slats as a sun protection element are known from the prior art. An example of this is in Scripture FR-A-2 327 385 disclosed.
- the slat described here consists of preformed steel sheets, which are pressed end with profile strips and whose interior is filled with a plastic foam. These slats are relatively heavy due to their metallic material and require a heavy supporting structure to hold the slats and adjust in their angular position to the prevailing lighting conditions can.
- a sunblind is found in the DE 297 22 219 U , Again, a flat strip is inserted into a Einsteckschlitze, which are formed in the lamella delimiting edge profiles, wherein the flat strip also forced by abutment into a curved shape. Again, the sunblind is comparatively heavy.
- the sun protection lamella of the type mentioned is characterized in that the cover layer consists of a stretchable Folienund / or fabric material and is held stationary by holders on at least one profile and / or at least one cross strut under bias.
- plastic films, glass fiber fabric or similar material which is extremely light on the one hand compared to metallic materials, but still remains dimensionally stable even with thermal fluctuations and throws no wrinkles, sags or fluttering in the wind.
- the thin material allows a design that still allows light to fall through.
- the film or fabric may be coated or finished so that certain wavelengths are filtered out of the light. In this way it is possible to still let enough light fall into the building, although the heat radiation is filtered out by the sunblinds.
- the cover layer is therefore in terms of their translucency between metal blades and glass fins, but both are heavier.
- the light transmission is influenced, for example by the mesh size of the fabric, the choice of material and mixture and a possible coating.
- the lamellae according to the invention can be produced inexpensively.
- the support structures can be made much easier and more cost effective.
- the dimensions and properties the sunscreen blades according to the invention can be easily adapted to individual needs. Different geometries, shapes and colors can be represented with the system.
- a support surface is provided in particular as a holder, on which the cover layer rests under pretension.
- the bias causes a frictional engagement between the cover layer and the support surface, whereby the cover layer is fixed in position.
- a holder for the cover into consideration, such as a terminal block in which the cover layer is clamped held non-positively, or connected to the cover mold body such as a Klemmwulst, which is insertable into a receiving opening that thereby the cover layer after final assembly of the slat frame is positively fixed in position under bias.
- sunshade having multiple sunblinds 2.
- sunblinds 2 are arranged in a support structure 3 and in different pivot positions, as in Fig. 1 illustrates to convict.
- actuating linkage 4 over which they are in an upright open position and in the Fig. 1 indicated closed position to be transferred.
- each sunblind 2 has a cross strut 5 with side profiles 6 and longitudinal edge profiles, are inserted into the grooves 7, which serve as a receptacle for the end pieces 8 and 9 respectively.
- Cross struts 5 and 6 profiles together form the slat frame 14.
- end pieces 8 and 9 of a cover layer 10 made of a film material used.
- This cover layer 10 is formed as a tension track, so that it spans the cross member 5 as a sun protection element.
- the cover layer can be attached on one or both sides and executed in one or more layers.
- the cover layer 10 is preferably made of a translucent material which transmits a diffused light, for example with a transmittance between 10 and 20%, by which a glare protection is ensured.
- a translucent material which transmits a diffused light
- the illuminance can be regulated in the respective offices, so that in interaction with artificial light consistent, glare-free Lighting conditions can be created.
- the slats can also be moved individually per room.
- Suitable materials for the cover layer 10 are all substances or combinations of substances which can be tensioned due to their specific property or processing method, for example in a woven fabric, with overstretching. This applies for example to polyester or silicone, but also coated glass fiber fabric.
- the fiberglass fabric can be heated and coated with PTFE, as needed several times, until the required parameters such as stiffness, tear resistance, weathering resistance, fire behavior, stretch and elongation, light transmittance and appearance are met.
- the tensionability in particular the stress with a tensile stress is of importance, since this is the preferred type of stress in the concrete use.
- the flexible properties of the material used make it possible to subject the material to tensile stress, as this makes it easy to keep in shape and position.
- the cross strut 5 in FIG. 2 has a central region 11, which projects beyond the profiles 6 at the top, and in which additionally a spring element 12 can be used, which is indicated only schematically.
- the cover layer 10 can also be additionally biased in the middle of the sunblind 2, but what in Fig. 2 the sake of clarity is not shown in detail.
- At least one of the end pieces 8 and 9 is formed as a clamping bead, through which the cover layer 10 is fixable in its position to the profile 6.
- the cover layer 10 is biased to a desired level and, if necessary, also re-tensioned via the spring mechanism 11 and 12. As shown in the embodiment, the cover layer 10 is pulled around the profile 6 around, so that the cover layer 10, the profile 6 partially bounded.
- the boundary angle is in the exemplary embodiment about 170 °. Depending on the requirements in the application The boundary angle can also be larger or smaller.
- the pulling of the cover layer 10 by a profile 6 or a transverse strut 5 equalizes the tension and presses the cover layer 10 on the support surface 15.
- the voltage can be well introduced into the slat frame 14.
- the lower flange 13 ensures that according to Fig. 2 be exerted by the bias of the cover layer 10 on the crossbar 5 no vertical loads.
- the rounded outer contours of the profiles 6 serve as support surface 15 for the cover layer 10.
- an additional support surface 15 forms the middle region 11.
- the cover layer 10 of the corresponding film material can be designed according to the most diverse requirements.
- various, even multi-layered film materials can be provided in a relatively simple manner, which can also be exchanged and replaced when the sunshade is installed. This can be done with a relatively simple effort. So also films for different seasons or with regard to design measures can be used to realize, for example, different lighting effects.
- a sun protection device is thus provided, which is extremely flexible compared to conventional sun protection devices and build much easier.
- the profiles 6 have end receptacles 16, in which the cross struts 5 are inserted.
- the Receivers 16 are preferably formed so that the cross struts 5 fit fit into the receptacles 16.
- the transverse struts 5 can be connected by screwing with the screw holes 17 which are arranged in the profiles 6 in the region of the receptacles 16.
- the stability of the slat frame 14 is increased by the combination of positive connection and additional fasteners and simplifies installation.
- the profiles 6 have fastening elements 18 to which a mounting tool can be fastened. As fasteners are, for example screw holes, bolts, recesses for receiving form-fitting brackets, etc. into consideration, which preferably allow fast attachment and detachment of the assembly tools.
- the slat frame 14 can be easily mounted, but more difficult is the tensioning of the cover layer 10.
- the clamping can, for example be accomplished by an end piece 8, 9 is connected to a tension roller not shown, the rotation of the cover layer 10 rolls up and thereby offset under tension. The tension roller must then be fixed.
- a disadvantage is the additional effort for the idler and the maintenance requirements for moving components.
- the cover layer 10 can be easily re-tensioned. In this case serve as a holder, the support surfaces 15 and the tension roller with which the cover layer 10 is set under tension.
- the attachment of the end pieces 8, 9 on the profiles 6 is easy, but it is more difficult to mount the slat frame so that the cover layer 10 is still under a bias.
- this problem can be overcome by attaching an assembly tool to the profiles at the ends and then moving apart the attachment points of the assembly tool. When a desired preload is reached, the mounting tool is stopped and the cross braces 5 can be easily mounted.
- the holder for the cover layer 10 consists of the combination of the bearing surfaces 15 with the fastening means with which the cover layer 10 is fixed with its end pieces 8,9 to the profiles 6.
- the third proposed assembly method is similar to the second, but differs by the tubular formation of the cover layer 10.
- the profiles 6 instead of inserting the profiles 6 in the hose, it is also possible to bring the profiles 6, for example by means of the mounting tool in a mounting position, the hose over the Lay profiles 6 and then move the profiles apart.
- the method using a hose forces to a double-layer cover layer 10, but has the advantage that before moving apart of the profiles 6, the end pieces 8, 9 need not be connected to the profiles 6 and the cover layer 10 is exclusively positioned by the bias on the support surfaces 15.
- the bearing surfaces 15 thus serve as exclusive holders for the cover layer 10.
- retightening the cover layer 10 is possible only with increased effort.
- the bias is chosen to be sufficiently large.
- the cover layer 10 can expand even with greater heat, without thereby loosens the top layer, wrinkles or sags.
- a sufficient preload can be 1.5 kN, which can be reduced to as little as 0.5 kN during assembly to keep the fabric taut.
- the sunblinds 2 according to the invention are to be tightened anyway, this can be done by one or both profiles 6 are released from the crossbar 5, the profiles 6 are moved further apart, and either a longer crossbar 5 is installed in the sunblind 2 or the original cross strut 5 in other fferlochkombinationen with the profiles 6 is fixed again.
- the transverse strut 5 and / or the profiles 6 in the attachment region have a plurality of mounting options, which allow a variation of the relative distances to each other.
- the bias can also be prepared by the cover layer 10 is held by a profile 6 and / or a cross strut 5, wherein as a counter-holder, for example, clamps or moldings can be used to determine the cover layer 10 at a suitable position on the slat frame 14th are attached.
- the transverse profiles 5 should then also bearing surfaces 15, wherein as a support surface 15 in extreme cases, the upper edge of the profile cross-section of the transverse profile 5 is used.
- a slightly larger bearing surface 15, which additionally has an angular position and possibly a surface rounding brings advantages. The methods for producing the sun protection profiles 2 can be applied accordingly.
- FIG. 4 as a cross-sectional view through a profile 6, the support surfaces 15 can be seen well.
- the edge region of the profile cross section shows a semi elliptical shape.
- the groove 7, in the end pieces 8 and 9 are inserted, the screw holes 17 and the fasteners 18 are easy to see. If the lugs of the screw holes 17 and the fasteners 18 extend over the length of the profile 6, they can also be used as static stabilizing means that prevent or reduce bending of the profile 6 during assembly. Otherwise, the profile 6 has large bearing surfaces 15, which distribute the acting on the cover layer 10 bias and other loads acting on the cover layer 10, such as wind, snow, foliage, etc., evenly on the construction of the sunblind 2. Hollow chambers in the profiles 6 keep the weight of the slat frame 14 as large as possible despite large contact surfaces 15.
- FIG. 5 is a side view of a solar shading 2 according to the invention shown, which is provided with a tubular cover layer 10.
- the profiles 6 are held by the cross strut 5 spaced from each other.
- the actuating linkage 4 is attached on the crossbar 5 .
- the crossbar 5 can still be placed clamps, decorative cover or other elements not shown.
- a very lightweight and slim design can be realized by the construction of the invention, can be bridged by a single sunblind 2 with small demands on the support structure large spans and / or heights.
- the costs for the supporting structure are correspondingly lower.
- the cross-sectional profile of the sunblind 2 barely obstructs the view out of the building, especially as with larger area coverage less sunblinds 2 for shading a given building surface are required.
Abstract
Description
Die vorliegende Erfindung bezieht sich auf eine Sonnenschutzlamelle mit einem Lamellenrahmen, der gegenüberliegende, sich über die Länge der Sonnenschutzlamelle erstreckende Profile und diese miteinander verbindenden Querstreben umfaßt, und einer am Lamellenrahmen befestigten Deckschicht.The present invention relates to a sunblind with a slat frame comprising opposite, extending over the length of the sunblind profiles and these interconnecting cross struts, and attached to the slat frame cover layer.
Lamellen als Sonnenschutzelement sind aus dem Stand der Technik bekannt. Ein Beispiel dafür ist in der Schrift
Ein anders Beispiel findet sich in der Schrift
Ein weiteres Beispiel für eine Sonnenschutzlamelle findet sich in der
Es ist die Aufgabe der vorliegenden Erfindung, eine Sonnenschutzlamelle der eingangs genannten Art zur Verfügung zu stellen, die leichter baut.It is the object of the present invention to provide a sunblind of the type mentioned, which is easier to build.
Zur Lösung dieser Aufgabe zeichnet sich die Sonnenschutzlamelle der eingangs genannten Art dadurch aus, daß die Deckschicht aus einem dehnbaren Folienund/oder Gewebematerial besteht und von Haltern an zumindest einem Profil und/oder zumindest einer Querstrebe unter Vorspannung ortsfest gehalten ist.To solve this problem, the sun protection lamella of the type mentioned is characterized in that the cover layer consists of a stretchable Folienund / or fabric material and is held stationary by holders on at least one profile and / or at least one cross strut under bias.
Bei dieser Merkmalskombination ist es möglich, Kunststoffolien, Glasfasergewebe oder vergleichbares Material zu verwenden, welches einerseits im Vergleich zu metallischen Werkstoffen extrem leicht ist, trotzdem aber auch bei thermischen Schwankungen formstabil bleibt und keine Falten wirft, durchhängt oder im Wind flattert.With this combination of features, it is possible to use plastic films, glass fiber fabric or similar material, which is extremely light on the one hand compared to metallic materials, but still remains dimensionally stable even with thermal fluctuations and throws no wrinkles, sags or fluttering in the wind.
Das dünne Material erlaubt eine Auslegung, bei der trotzdem noch Licht hindurchfallen kann. Die Folie oder das Gewebe kann so beschichtet oder ausgerüstet sein, daß bestimmte Wellenlängen aus dem Licht ausgefiltert werden. Auf diese Weise ist es möglich, immer noch ausreichend Licht in das Gebäude fallen zu lassen, obwohl die Wärmestrahlung von den Sonnenschutzlamellen ausgefiltert wird. Die Deckschicht liegt also hinsichtlich ihrer Lichtdurchlässigkeit zwischen Metallamellen und Glaslamellen, die aber beide schwerer sind. Die Lichtdurchlässigkeit ist beeinflußbar, beispielsweise durch die Maschenweite des Gewebes, die Materialauswahl und -mischung und eine eventuelle Beschichtung. Die erfindungsgemäßen Lamellen sind kostengünstig herstellbar. Auch die Haltekonstruktionen können wesentlich leichter und kostensparender ausgeführt werden. Die Abmessungen und Eigenschaften der erfindungsgemäßen Sonnenschutzlamellen können sehr leicht auf die individuellen Bedürfnisse angepaßt werden. Mit dem System sind unterschiedliche Geometrien, Formen und Farben darstellbar.The thin material allows a design that still allows light to fall through. The film or fabric may be coated or finished so that certain wavelengths are filtered out of the light. In this way it is possible to still let enough light fall into the building, although the heat radiation is filtered out by the sunblinds. The cover layer is therefore in terms of their translucency between metal blades and glass fins, but both are heavier. The light transmission is influenced, for example by the mesh size of the fabric, the choice of material and mixture and a possible coating. The lamellae according to the invention can be produced inexpensively. The support structures can be made much easier and more cost effective. The dimensions and properties the sunscreen blades according to the invention can be easily adapted to individual needs. Different geometries, shapes and colors can be represented with the system.
Als Halter kommen verschiedene Elemente in Betracht. So ist als Halter insbesondere eine Auflagefläche vorgesehen, auf der die Deckschicht unter Vorspannung aufliegt. Die Vorspannung bewirkt einen Reibschluß zwischen Deckschicht und Auflagefläche, wodurch die Deckschicht in ihrer Lage fixiert wird. Es kommen aber auch andere Ausgestaltungen eines Halters für die Deckschicht in Betracht, so beispielsweise eine Klemmleiste, in der die Deckschicht eingeklemmt kraftschlüssig gehalten ist, oder ein mit der Deckschicht verbundener Formkörper wie beispielsweise ein Klemmwulst, der so in eine Aufnahmeöffnung einlegbar ist, daß dadurch die Deckschicht nach fertiger Montage des Lamellenrahmens formschlüssig unter Vorspannung lagefixiert ist.As a holder, various elements come into consideration. Thus, a support surface is provided in particular as a holder, on which the cover layer rests under pretension. The bias causes a frictional engagement between the cover layer and the support surface, whereby the cover layer is fixed in position. But there are also other embodiments of a holder for the cover into consideration, such as a terminal block in which the cover layer is clamped held non-positively, or connected to the cover mold body such as a Klemmwulst, which is insertable into a receiving opening that thereby the cover layer after final assembly of the slat frame is positively fixed in position under bias.
Weitere Ausgestaltungen der Erfindung ergeben sich aus den Merkmalen der Unteransprüche, der nachfolgenden Beschreibung sowie den beigefügten Zeichnungen.Further embodiments of the invention will become apparent from the features of the subclaims, the following description and the accompanying drawings.

Wie näher aus
Die Deckschicht 10 besteht bevorzugt aus einem lichtdurchlässigen Material, das ein diffuses Licht durchläßt, beispielsweise mit einem Transmissionsgrad zwischen 10 und 20 %, durch den ein Blendschutz gewährleistet wird. Durch eine Kombination der motorischen Anstellwinkelverstellung der Sonnenschutzvorrichtung 1 mit einer sensorgestützten Steuerung kann die Beleuchtungsstärke in den jeweiligen Büros reguliert werden, so daß im Zusammenspiel mit Kunstlicht gleichbleibende, blendfreie Lichtverhältnisse geschaffen werden können. Je nach Steuerung/ Regelung können die Lamellen auch individuell pro Raum verfahren werden.The
Als Material für die Deckschicht 10 kommen alle Stoffe oder Stoffkombinationen in Betracht, die aufgrund ihrer spezifischen Eigenschaft oder Verarbeitungsweise, beispielsweise in einem Gewebe, mit Überdehnung spannbar sind. Dies gilt beispielsweise für Polyester oder Silikon, aber auch beschichtetes Glasfasergewebe. Das Glasfasergewebe kann erhitzt und mit PTFE beschichtet werden, nach Bedarf mehrfach, bis die erforderlichen Parameter wie Steifigkeit, Reißfestigkeit, Witterungsbeständigkeit, Brandverhalten, Spann- und Dehnbarkeit sowie Lichtdurchlässigkeit und Optik erfüllt sind. Hinsichtlich der Spannbarkeit ist insbesondere die Belastung mit einer Zugspannung von Bedeutung, da dies die in der konkreten Verwendung bevorzugte Spannungsart ist. Bei den flexiblen Eigenschaften des verwendeten Materials bietet es sich an, das Material einer Zugspannung auszusetzen, da es dadurch gut in Form und Position gehalten werden kann.Suitable materials for the

Die Deckschicht 10 aus dem entsprechenden Folienmaterial kann den unterschiedlichsten Anforderungen entsprechend ausgebildet sein. So lassen sich auf relativ einfache Weise verschiedene, auch mehrschichtige Folienmaterialien vorsehen, die auch bei eingebauter Sonnenschutzeinrichtung ausgetauscht und ausgewechselt werden können. Die ist mit einem relativ einfachen Aufwand vollziehbar. So können auch Folien für unterschiedliche Jahreszeiten oder auch im Hinblick auf gestalterische Maßnahmen Verwendung finden, um beispielsweise auch unterschiedliche Lichteffekte zu realisieren.The
Insgesamt ist damit eine Sonnenschutzeinrichtung zur Verfügung gestellt, die gegenüber herkömmlichen Sonnenschutzeinrichtungen außerordentlich flexibel ist und wesentlich leichter baut.Overall, a sun protection device is thus provided, which is extremely flexible compared to conventional sun protection devices and build much easier.
In
Zur Herstellung einer Vorspannung der Deckschicht 10 sind prinzipiell mehrere Verfahren denkbar: entweder wird die Deckschicht 10 auf einen fertig hergestellten Lamellenrahmen 14 aufgelegt, ein Endstück 8,9 an diesem fixiert und sodann das gegenüberliegende Endstück 8,9 auf eine Weise mit dem gegenüberliegenden Profil 6 befestigt, bei der es unter eine Vorspannung gesetzt wird, oder die Deckschicht 10 wird mit jeweils einem der Endstücke 8,9 mit jeweils einem Profil 6 fest verbunden, und die Profile 6 werden mit einem Montagewerkzeug so weit auseinanderbewegt, daß die Deckschicht 10 unter eine Vorspannung gerät, wonach dann der Abstand zwischen den Profilen 6 und damit die Vorspannung durch Einlegen und Befestigen der Querstreben 5 mit den Profilen 6 aufrecht erhalten bleibt, oder die Deckschicht 10 ist schlauchförmig ausgebildet, indem die gegenüberliegenden Kanten einer Materialbahn miteinander verbunden sind, die Profile 6 werden innen in den Schlauch eingelegt, mittels des Montagewerkzeugs auseinander bewegt und durch die Montage der Querstreben 6 lagefixiert wie vorstehend beschrieben.In principle, several methods are conceivable for producing a pretensioning of the cover layer 10: either the
Im ersten Montageverfahren kann der Lamellenrahmen 14 leicht montiert werden, schwieriger ist jedoch das Spannen der Deckschicht 10. Das Spannen kann beispielsweise bewerkstelligt werden, indem ein Endstück 8, 9 mit einer nicht näher dargestellten Spannrolle verbunden ist, deren Drehung die Deckschicht 10 aufrollt und dadurch unter Zugspannung versetzt. Die Spannrolle muß sodann festgelegt werden. Nachteilig ist der zusätzliche Aufwand für die Spannrolle und der Wartungsbedarf für bewegliche Komponenten. Andererseits kann die Deckschicht 10 leicht nachträglich nachgespannt werden. In diesem Fall dienen als Halter die Auflageflächen 15 sowie die Spannrolle, mit der die Deckschicht 10 unter Zugspannung gesetzt ist.In the first assembly method, the
Im zweiten Montageverfahren ist die Befestigung der Endstücke 8, 9 an den Profilen 6 leicht, schwieriger ist es jedoch, den Lamellenrahmen so zu montieren, daß die Deckschicht 10 immer noch unter einer Vorspannung steht. Dieses Problem kann jedoch bewältigt werden, indem ein Montagewerkzeug endseitig an den Profilen befestigt wird und dann die Befestigungspunkte des Montagewerkzeugs auseinander bewegt werden. Ist eine gewünschte Vorspannung erreicht, wird das Montagewerkzeug gestoppt, und die Querstreben 5 können leicht montiert werden. Auch hier besteht der Halter für die Deckschicht 10 aus der Kombination der Auflageflächen 15 mit den Befestigungsmitteln, mit denen die Deckschicht 10 mit ihren Endstücken 8,9 an den Profilen 6 befestigt ist.In the second mounting method, the attachment of the
Das dritte vorgeschlagene Montageverfahren ähnelt dem zweiten, unterscheidet sich jedoch durch die schlauchförmige Ausbildung der Deckschicht 10. Statt die Profile 6 in den Schlauch einzulegen, ist es auch möglich, die Profile 6 beispielsweise mittels des Montagewerkzeugs in eine Montageposition zu bringen, den Schlauch über die Profile 6 zu legen und dann die Profile auseinander zu bewegen. Das Verfahren unter Verwendung eines Schlauchs zwingt zu einer doppellagigen Deckschicht 10, weist jedoch den Vorteil auf, daß vor dem Auseinanderfahren der Profile 6 die Endstücke 8, 9 nicht mit den Profilen 6 verbunden werden müssen und die Deckschicht 10 ausschließlich durch die Vorspannung ortsfest auf den Auflageflächen 15 positioniert ist. Die Auflageflächen 15 dienen so als ausschließliche Halter für die Deckschicht 10.The third proposed assembly method is similar to the second, but differs by the tubular formation of the
Bei den beiden letztgenannten Verfahren ist ein Nachspannen der Deckschicht 10 nur mit erhöhtem Aufwand möglich. Es ist jedoch auch nicht erforderlich, wenn die Vorspannung ausreichend groß gewählt ist. Bei einer ausreichenden Vorspannung kann sich die Deckschicht 10 selbst bei größerer Hitzeeinwirkung ausdehnen, ohne daß sich dadurch die Deckschicht lockert, Falten wirft oder durchhängt. Eine ausreichende Vorspannung kann beispielsweise 1,5 kN betragen, die sich im Rahmen der Montage auf bis zu 0,5 kN verringern kann, um den Stoff noch gespannt zu halten. Sollen die erfindungsgemäßen Sonnenschutzlamellen 2 trotzdem nachgespannt werden, kann dies erfolgen, indem ein oder beide Profile 6 von der Querstrebe 5 gelöst werden, die Profile 6 weiter auseinander bewegt werden, und entweder eine längere Querstrebe 5 in die Sonnenschutzlamelle 2 eingebaut wird oder die ursprüngliche Querstrebe 5 in anderen Schraublochkombinationen mit den Profilen 6 wieder befestigt wird. Dazu ist es vorteilhaft, wenn die Querstrebe 5 und/oder die Profile 6 im Befestigungsbereich mehrere Befestigungsmöglichkeiten aufweisen, die eine Variation der relativen Abstände zueinander zulassen.In the latter two methods, retightening the
Es ist vorstellbar, die Deckschicht 10 nicht nur in einer Richtung, sondern zusätzlich in einer weiteren Richtung zu spannen. Eine Festlegung an den gegenüberliegenden Seiten der zweiten Spannungsrichtung kann beispielsweise durch die Montage von Klemmplatten erfolgen, die die Deckschicht 10 auf Elementen des Lamellenrahmens 14 fixieren. Die Vorspannung kann jedoch auch in der zweiten Richtung auf die hier schon vorstehend erwähnten Weisen erfolgen.It is conceivable to tension the
In den Ausführungsbeispielen sind nur Sonnenschutzlamellen 2 gezeigt, bei denen die Deckschicht 10 zwischen gegenüberliegenden Profilen 6 gespannt ist. Erfindungsgemäß kann die Vorspannung aber auch hergestellt werden, indem die Deckschicht 10 von einem Profil 6 und/oder einer Querstrebe 5 gehalten ist, wobei als Gegenhalter beispielsweise Klemmen oder Formkörper zur Festlegung der Deckschicht 10 verwendet werden können, die an einer geeigneten Position am Lamellenrahmen 14 befestigt sind. Im Rahmen der Erfindung ist es auch möglich, die Deckschicht 10 mit Hilfe zumindest eines Querprofils 5 zu spannen. Bevorzugt sollten die Querprofile 5 dann auch Auflageflächen 15 aufweisen, wobei als Auflagefläche 15 im Extremfall auch die Oberkante des Profilquerschnitts des Querprofils 5 verwendbar ist. Eine etwas größere Auflagefläche 15, die zusätzlich eine winklige Anstellung und gegebenenfalls eine Oberflächenrundung aufweist, bringt jedoch Vorteile. Die Verfahren zur Herstellung der Sonnenschutzprofile 2 können entsprechend angewendet werden.In the embodiments, only

Insgesamt kann durch den erfindungsgemäßen Aufbau eine sehr leichte und schlanke Konstruktion realisiert werden, durch die mit geringen Anforderungen an die Tragkonstruktion große Spannweiten und/oder Höhen durch eine einzelne Sonnenschutzlamelle 2 überbrückt werden können. Die Kosten für die Tragkonstruktion fallen entsprechend niedriger aus. In aufgeklappter Stellung behindert das Querschnittsprofil der Sonnenschutzlamelle 2 kaum die Sicht aus dem Gebäude heraus, zumal bei größerer Flächenabdeckung weniger Sonnenschutzlamellen 2 zur Abschattung einer gegebenen Gebäudefläche erforderlich sind.Overall, a very lightweight and slim design can be realized by the construction of the invention, can be bridged by a
