Sonneneinstrahlungsschutz und/oder als flexible Wärmedämmung. F.ALTJAbOUSIE AS} 'SEXI3LE WARM INSULATION The invention relates to variable, or along a reference plane. collapsible structures for arrangement behind windows or translucent facade or roof elements for use as sun exposure or protection against solar radiation and / or as flexible thermal insulation.
Es ist bekannt Jalousien als Faltwände auszubilden. Derartige, sog. Paltåalousien werden jedoch nur als Sonnen- bzw. Wärme= energieeinstrahlungsschutz verwendet. Es bietet sich Jedoch an, Sonnenschutzeinrichtungen derart auszubilden, daß sie gleichzeitig einen terbesserten Wärmeschutz für den Innenraum darstellen und gegenüber der eingestrahlten Wärme energie und gegenüber der Temperaturdifferenz zwischen Innen- und Außenraum insbesondere nachts eine wärmeisolierende Wirkung haben.It is known to design blinds as folding walls. Such, so-called. Paltåalousien are only used as sun or heat = energy protection used. However, it is advisable to design sun protection devices in such a way that that they also represent a better thermal protection for the interior and in relation to the radiated heat energy and in relation to the temperature difference a heat-insulating effect between indoor and outdoor spaces, especially at night to have.
Die Erfindung hat sich daher zur Aufgabe gestellt, zusammen faltbare Sonnenschutzeinrichtungen gleichzeitig als Wärmeiso= lationsmaßnahme auszubilden.The invention has therefore set itself the task of collapsible To train sun protection devices as heat insulation measures at the same time.
Diese Aufgabe wird erfindungsgemä.ß dadurch gelöst, daß das zu= sammenfaltbare Gebilde im aufgefalteten Zustand eine Vielzahl aneinendergereihter Hohlräume umschließt.This object is achieved according to the invention in that the collapsible Structure in the unfolded state encloses a large number of lined up cavities.
Die Hohlräume umschließen eine stehende Luftschicht, die als Isolation wirkt.The cavities enclose a standing layer of air that acts as insulation works.
Die Figuren stellen unterschiedliche Möglichkeiten der Hohle raumbildung bzw. der flexiblen, faltbaren Wandung dar. Es zei gen: Fig. 1 eine einschichtige wabenförmige Faltwand Fig. 2 die Faltung der wabenförmigen Struktur Fig. 3 die zusammengefaltete Wand Fig. 4 eine dreischichtige wabenförmige Struktur Fig. 5 die Faltung und Zusammensetzung der wabenförmigen Struktur Fig. 6 die zusammengefaltete Wand.The figures represent different ways of creating cavities or the flexible, foldable wall. It show: Fig. 1 a single-layer honeycomb-shaped folding wall FIG. 2 the folding of the honeycomb-shaped structure FIG. 3 the folded up Wall Fig. 4 a three-layer honeycomb structure Fig. 5 the folding and assembly the honeycomb structure Fig. 6 the folded wall.
Figur 1 zeigt eine einschichtige FaltJalousie 10, die aus einer Vielzahl längs einer Bezugsebene angeordneter Waben 11 gebildet wird. Wie durch die Lichtstrahlung 24 angedeutet, sind die Wan= dungen aus einer strahlungsdurchlässigen Membran gebildete Die Strahlendurchgangsbreite 12 wird durch den Abstand 13 der Be rührungsflächeii 14 der Waben 11 und durch die Breite 15 der Berührungsflächen bestimmt. Die Flächen 14 können durch Lamellen verstärkt werden.Figure 1 shows a single-layer pleated blind 10, which consists of a plurality honeycombs 11 arranged along a reference plane is formed. Like the light radiation 24 indicated, the walls are formed from a radiation-permeable membrane The beam passage width 12 is determined by the distance 13 of the loading surface 14 of the honeycombs 11 and determined by the width 15 of the contact surfaces. The surfaces 14 can be reinforced by slats.
Figur 2 zeigt die Hertsellung der Waben durch Faltung einer Fläche zu einer Zwillingswabe, so daß sich an den Berührungss flächen 14 ein Überlappungsstoß ergibt. Eine Zusammenfügung meherer Zwillingswaben längs einer Bezugsebene 16 ergibt die Faltjalousie. Der Begriff Bezugsebene ist grundsätzlich rein geometrisch und nicht räumlich zu verstehene Die Bezugsebene kann horizontal, vertikal oder schief gelegen sein.FIG. 2 shows the production of the honeycomb by folding a surface to a twin honeycomb, so that on the contact surfaces 14 an overlap joint results. An assembly of several twin honeycombs along a reference plane 16 results the pleated blind. The term reference plane is basically purely geometric and not spatially understood The reference plane can be horizontal, vertical or oblique be located.
Figur 3 stellt die Faltjalousie 10 in zusammengefaltetem Zul stand dar. In Zusammengefaltetem Zustand werden die Löcher zur Durchführung der Aufhängung durchgestanzt.FIG. 3 shows the pleated blind 10 in the folded-up position when folded, the holes for the suspension punched through.
Figur 4 stellt eine mehrschichtige Faltjalousie 17 dar. Diese besteht aus drei wabenförmigen Hohlraumschichten 18, 19g 20 und bildet damit eine sehr gute Wärmeisolation. Auch diese Jalousie kann lichtdurchlässig ausgebildet werden, Figur 5 zeigt die Faltung der Zwillingswaben 21 aus einer Fläche.FIG. 4 shows a multi-layer pleated blind 17. This consists of three honeycomb-shaped cavity layers 18, 19g 20 and thus forms a very good one Thermal insulation. This blind can also be made translucent, figure 5 shows the folding of the twin honeycombs 21 from one surface.
In diesem Fall bildet sich zwischen den Waben ein Überlappungs= stoß 22 als Abstandhalter zwischen der Zwillingswabe aus. Die Zwillingswaben 21 werden senkrecht zur Bezugsebene 16 angeord= net. Je zwei Zwillingswaben umschließen einen weiteren waben förmigen Raum>23. Figur 6 zeigt diese FaltJalouele in zusammen= gelegtem Zustand.In this case, an overlap joint is formed between the honeycombs 22 as a spacer between the twin honeycomb. The twin honeycombs become 21 angeord = net perpendicular to the reference plane 16. Two twin honeycombs each enclose one another honeycomb-shaped room> 23. Figure 6 shows this FaltJalouele together = laid condition.
Figur 7 stellt eine alternative Hohlkörperausbildung dar. Die Hohlkörper 25 werden aus flexiblen Kunststoffschläüchen gebil det, die längs aussteifenden Lamellen 26 geklebt werden. Die Lamellen sind in der Art einer handelsüblichen Jalousie ausge bildet. Selbstverständlich wäre an Stelle der Kunststoffschläu= che auch ein beidseitiges Bespannen der Jalousie möglich.FIG. 7 shows an alternative hollow body design. The hollow bodies 25 are gebil det from flexible plastic hoses that stiffen the lengthways Lamellae 26 are glued. The slats are like a standard blind educated. Of course, a plastic tube would also be used in place of the plastic tubing The blinds can be covered on both sides.
Das Material für die Hohlkörperwandungen ist lichtundurchlässig oder lichtdurchlässig bzw. durchscheinend und besteht aus Papier, gestärktem Stoff oder aus Kunststoffolien.The material for the hollow body walls is opaque or translucent or translucent and is made of paper, starched fabric or made of plastic films.
Besonders vorteilhaft ist es, die Wandungen wärmestrahlungsre= flektierend (selektiv) auszubilden. Entsprechend dem Verwen= dungszweck können eine oder mehrere Wandungen auch lichtstrah= lungsreflektierend ausgebildet werden. Damit ist einerseits eine Wärmeentwicklung infolge Sonnenstrahlung verhindert (Son= nenschutz), andererseits kann die Jalousie auch als Reflexion system für einen Strahler verwendet werden. Bei spiegelnder Beschichtung eignet sich als Material zur Herstellung der Hohl3 körper aluminiumbedampfte Kunststoffolien.It is particularly advantageous for the walls to reflect heat radiation (selectively) to train. Depending on the intended use, one or more Walls can also be designed to reflect light radiation. So on the one hand prevents heat build-up as a result of solar radiation (sun protection), on the other hand the blind can also be used as a reflection system for a spotlight. In the case of a reflective coating, the material used to manufacture the hollow 3 body aluminum-coated plastic foils.
Eine vorteilhafte Variante besteht in einer absorbierenden Be= schichtung der Einstrahlungsseite und der Verwendung der Ja= lousie zur Solarenergiegewinnung.An advantageous variant consists in an absorbent coating the irradiation side and the use of the curtain to generate solar energy.
Die erfindungsgemäße Sonnenschutzåalousie eignet sich auf Grund der guten Wärmeisolation insbesondere nachts zur Isolation in Fensternischen und stellt damit eine einfache Energiesparmaß3 nahme dar.The sun protection blinds according to the invention is suitable due to the good thermal insulation especially at night for insulation in window niches and places thus a simple energy saving measure.
Auf Grund der Steifigkeit der wabenförmigen Struktur, lassen sich derartige Jalousien mit besonderem Vorteil auch als leichte Raumabtrennungen verwenden.Due to the rigidity of the honeycomb structure, can Use such blinds with particular advantage as light room partitions.
