Description

Die vorliegende Erfindung bezieht sich auf eine Lamelle gemäss dem Oberbegriff des Anspruchs 1 und eine Beschattungseinrichtung gemäss dem Oberbegriff des Anspruchs 6.The present invention relates to a slat according to the preamble of claim 1 and a shading device according to the preamble of claim 6.

Zum dosierten Einlassen von Licht in einen Raum sind Beschattungseinrichtungen mit Lamellen bekannt. So gibt es Beschattungseinrichtungen wie Lamellenstoren, Klappladen und dgl. mit horizontalen Lamellen und es gibt aus Lamellen bestehende Vorhänge mit vertikalachsigen Lamellen, wobei bei den einen wie den andern zur Veränderung des Lichteinlasses die Lamellen um ihre Achse schwenkbar sind. Bei Horizontal- und Vertikallamellen lassen sich die Lamellen zusammenschieben; die Horizontallamellenstores nach oben und die Vertikallamellenstores zur Seite hin.Shading devices with slats are known for the metered introduction of light into a room. There are shading devices such as slatted blinds, folding shutters and the like with horizontal slats and there are curtains consisting of slats with vertical-axis slats, with the one and the other to change the light inlet, the slats can be pivoted about their axis. For horizontal and vertical slats, the slats can be pushed together; the horizontal slat blinds up and the vertical slat blinds to the side.

Benützt werden derartige Beschattungseinrichtungen nicht nur in Wohnräumen, Büroräumen und Fabrikationshallen sondern auch in Restaurants, Museen, Gewächshäusern und auch sonst überall dort, wo der Bedarf vorhanden ist, das von aussen durch Fenster und Glaswände einfallende Licht nicht ganz, sondern teilweise abzuhalten, wie beispielsweise auch in Eisenbahnwagen oder Strassenfahrzeugen.Such shading devices are used not only in living rooms, offices and production halls, but also in restaurants, museums, greenhouses and everywhere else where there is a need not to completely, but partly to prevent the light from outside through windows and glass walls, for example also in railroad cars or road vehicles.

Den bekannten Beschattungseinrichtungen ist gemeinsam, dass sie zur Hauptsache eine Funktion haben, nämlich, den Lichtdurchtritt und somit die Wärmestrahlung durch eine Fensteröffnung nach beiden Richtungen zu beschränken. Sei es, dass sie den Lichteintritt in einen Raum (vorallem den Eintritt direkter Sonnenstrahlung) begrenzen müssen, sei es, dass sie die Einsicht in den Raum von aussen (oder beides) zu erschweren haben. Das notwendige Vorhandensein solcher Beschattungseinrichtungen an den meisten Hochbauwerken hatte bis heute zur Folge, dass die Entwicklung ihrer Konstruktion und ihres Erscheinungsbildes in erster Linie auf eine Steigerung des Bedienungskomfortes und auf die Verwendung als Fassadenstilelemente zielte.The known shading devices have in common that their main function is to limit the passage of light and thus heat radiation through a window opening in both directions. Be that they have to limit the entry of light into a room (especially direct sunlight), either because they have to make it difficult to see into the room from outside (or both). The necessary presence of such shading devices on most high-rise buildings has meant that the development of their construction and appearance primarily aimed at increasing ease of use and using them as facade style elements.

Weiter ist es bekannt, an einzelnen Lamellen Funktionselemente wie Photozellen und Führungselemente für Schnüre zu befestigen.It is also known to attach functional elements such as photocells and guide elements for cords to individual lamellae.

Die vorliegende Erfindung stellt sich daher die Aufgabe gegenüber den bekannten, relativ flexiblen Lamellen, eine stabile Lamelle bzw. eine stabile Beschattungseinrichtung zu schaffen, die ohne Beeinträchtigung ihrer bisherigen technischen und ästhetischen Funktion weitere zusätzliche Funktionen übernehmen kann.The object of the present invention is therefore to create a stable slat or a stable shading device compared to the known, relatively flexible slats, which can take on additional functions without impairing its previous technical and aesthetic function.

Erfindungsgemäss wird diese Aufgabe gelöst durch die kennzeichnenden Merkmale des Anspruchs 1.According to the invention, this object is achieved by the characterizing features of claim 1.

Die Erfindung hat den Vorteil, dass an einem Grundmodell der Beschattungseinrichtung Zubehörelemente anbringbar sind, durch die die Beschattungseinrichtung entsprechend ihrem Einsatzort zusätzliche Funktionen übernehmen kann. Zudem kann eine bereits erstellte Beschattungseinrichtung mit zusätzlichen Funktionselementen nachgerüstet werden, wenn veränderte Umstände dies erfordern.The invention has the advantage that accessory elements can be attached to a basic model of the shading device, by means of which the shading device can perform additional functions in accordance with its place of use. In addition, a shading device that has already been created can have additional functional elements be retrofitted if changed circumstances require it.

Dank der Erfindung können Reflektorplatten an den Lamellen angebracht werden, die das Aussenlicht gezielt in einen Raum lenken oder streuen. Dadurch wird die Möglichkeit geschaffen - je nach Lage eines Raumes, nach Sonnenstand und Witterung - mehr Aussenlicht in einen Raum zu bringen als dies bei hochgezogener Beschattungseinrichtung möglich wäre. Dies schafft insbesondere bei klimatisierten Büroräumen Energiesparmöglichkeiten. Solche Büroräume sind oft zur Vergleichmässigung der Wirkung der Klimaanlage mit einer automatischen Beschattungseinrichtung versehen, welche bei direkter Sonneneinstrahlung den Lamellenbehang absenkt, den Raum beschattet und die elektrische Beleuchtung einschaltet. Deren abgestahlte Wärmemenge heizt indessen den Raum auf und muss während der warmen Jahreszeit durch die Klimaanlage abgebaut werden, was diese wiederum belastet. Dieser Nachteil beseitigt den Einsatz von Reflektorplatten; mittels der Lamellenstellung kann ein Raum meistens mit dem Aussenlicht allein optimal ausgeleuchtet werden - oder wenn doch noch eine künstliche Beleuchtung erforderlich ist - deren Beleuchtungsstärke mit einem handelsüblichen Lichtregler reduziert werden. Ist das sichtbare Anbringen von Reflektorplatten, wie zum Beispiel in den Anflugschneisen von Flughäfen untersagt, können die Reflektorplatten entsprechend dem Anspruch 6 angeordnet sein, wodurch sich auf der nach aussen gewandten Lamellenseite die Möglichkeit für das Anbringen von Wärmedämmleisten ergibt. Wärmedämmleisten hemmen einerseits die Wärmebelastung des Gebäudes oder dessen Wärmeverlust während der Nachtabsenkung der Heiztemperatur.Thanks to the invention, reflector plates can be attached to the slats, which direct or scatter the outside light into a room. This creates the possibility - depending on the position of a room, the position of the sun and the weather - to bring more outside light into a room than would be possible with the shading device raised. This creates energy saving opportunities, especially in air-conditioned offices. Such offices are often provided with an automatic shading device to even out the effect of the air conditioning system, which lowers the slatted curtain in direct sunlight, shadows the room and switches on the electric lighting. The amount of heat emitted heats up the room and must be removed by the air conditioning system during the warm season, which in turn puts a strain on it. This disadvantage eliminates the use of reflector plates; Using the slat position, a room can usually be optimally illuminated with the outside light alone - or if artificial lighting is still required - its illuminance can be reduced with a commercially available light controller. If the visible attachment of reflector plates, as for example prohibited in the approach aisles of airports, the reflector plates can be arranged according to claim 6, which results in the possibility of attaching thermal insulation strips on the outwardly facing slat side. Thermal insulation strips on the one hand inhibit the heat load of the building or its heat loss during the night reduction of the heating temperature.

Werden die Lamellen mit Sonnenzellen als Funktionselemente versehen, kann deren Energie zur elektrischen Steuerung und Betätigung der Beschattungseinrichtung verwendet werden, was die Elektrifizierungskosten solcher Beschattungseinrichtungen wesentlich senkt.If the slats are provided with sun cells as functional elements, their energy can be used for the electrical control and actuation of the shading device, which considerably reduces the electrification costs of such shading devices.

Wird der Beschattungseinrichtung eine Sicherheitsfunktion zugeordnet, kann das Funktionselement eine Abdeckung aus einem durchschusshemmenden Material, wie Hartmetallband und dgl. sein. Nachfolgend wird anhand der beiliegenden Zeichnung ein Ausführungsbeispiel der Erfindung beschrieben und es werden die damit erzielbaren Vorteile aufgezeigt. In der Zeichnung zeigt

If the shading device is assigned a safety function, the functional element can be a cover made of a bullet-resistant material, such as hard metal tape and the like. An exemplary embodiment of the invention is described below with reference to the accompanying drawing and the advantages which can be achieved thereby are shown. In the drawing shows

Die in der Zeichnung dargestellten und als Ganzes mit 1 bezeichneten Lamellen der Länge a und der Breite b bestehen im wesentlichen aus drei zusammen eine Platte bildenden Teilen, nämlich dem Mittelteil 5 und den beiden an diesen angrenzenden, in einer gemeinsamen Ebene liegenden ebenen Abschnitten 2 und 3, wobei der Mittelteil als mehrkantiger, die geometrische Längsachse 4 der Lamelle umhüllender Hohlkörper ausgebildet ist. Der Abschnitt 2 ist hier sowohl an seinem Rand 1c wie auch am gegenüberliegenden, an den Mittelteil 5 angrenzenden Rand 1d auf der Oberseite, das heisst der dem Lichteinfall zugewandten Seite mit je einem Steg 1e bzw. 1f versehen. Diese beiden Stege dienen zum Halten einer auf den Abschnitt 2 aufgeschobenen spiegelnden Platte 6. Bei dieser Platte kann es sich um eine Metallplatte, also beispielsweise eine polierte Aluminiumplatte handeln oder auch um eine mit einer spiegelnden Metallschicht versehene Glasplatte, also um einen Streifen aus verspiegeltem Glas.The lamellae of length a and width b shown in the drawing and designated as a whole by 1 essentially consist of three parts which together form a plate, namely the central part 5 and the two planar sections 2 and 11 adjoining them, lying in a common plane 3, the central part being designed as a polygonal hollow body enveloping the geometric longitudinal axis 4 of the lamella. The section 2 is here provided both on its edge 1c and on the opposite edge 1d adjacent to the central part 5 on the upper side, that is to say on the side facing the incidence of light, each with a web 1e or 1f. These two webs serve to hold a reflective plate 6 pushed onto section 2. This plate can be a metal plate, for example a polished aluminum plate, or a glass plate provided with a reflective metal layer, ie a strip of mirrored glass .

Wie man aus dem in der Fig. 2 dargestellten Ausschnitt aus einer erfindungsgemässen vor einer durchsichtigen Raumabschlusswand 19 angeordneten Beschattungseinrichtung ersehen kann, ist auf jeder Seite jedes Lamellen-Mittelteils 5 ein Lagerzapfen 7 eingesetzt, der aus einem in den polygonalen Hohlkörper 5 passenden Einsatz 7a, einem Hebelarm 7b und einem Achszapfen 7c gebildet wird. Jeder dieser Achszapfen ist in einem Lager 8 frei drehbar gehalten, wobei die Lager 8 am einen Lamellenende in einem Pfosten 9 und die Lager 8 am andern Lamellenende an einem Pfosten 10 befestigt sind.As can be seen from the detail shown in FIG. 2 of a shading device according to the invention arranged in front of a transparent room end wall 19, a bearing journal 7 is inserted on each side of each lamella middle part 5, which consists of an insert 7a, which fits into the polygonal hollow body 5, a lever arm 7b and a journal 7c is formed. Each of these journals is freely rotatably held in a bearing 8, the bearings 8 being attached to a post 9 at one lamella end and the bearing 8 being attached to a post 10 at the other lamella end.

Wie man der Fig. 3 entnehmen kann, sind die freien Enden der einzelnen Hebelarme 7b gelenkig mit einer Schubstange 13 verbunden, zu deren Höhenverstellung eine Gleitschiene 14 dient, die ihrerseits an einer auf einer Spindel 15 sitzenden Mutter 16 so befestigt ist, dass sie zusammen mit dem Spindelhalter 11 diese Mutter 16 gegen eine Verdrehung sichert. Diese Details sind in Fig. 2 nicht dargestellt, da sie im wesentlichen durch den Pfosten 9 verdeckt sind.As can be seen in FIG. 3, the free ends of the individual lever arms 7b are connected in an articulated manner to a push rod 13, for the height adjustment of which a slide rail 14 is used, which in turn is fastened to a nut 16 seated on a spindle 15 in such a way that it is together with the spindle holder 11 this nut 16 secures against rotation. These details are not shown in FIG. 2, since they are essentially covered by the post 9.

Diese Konstruktion hat nun zur Folge, dass sich die Lamellen nicht von selbst um ihre Achse verschwenken können, also fixiert sind, dass aber beim Betätigen des mit der Spindel verbundenen Winkelgetriebes 18 durch einen nicht dargestellten Motor oder eine Handkurbel die Mutter 16 nach oben oder unten verschoben wird, die ihrerseits die Schubstange 13 in der gleichen Richtung verschiebt, wodurch jede Lamelle 1 um ihre Achse 4 verschwenkt wird. Dadurch kann nicht nur erreicht werden, dass der Freiraum zwischen den einzelnen Lamellen verkleinert oder vergrössert und damit der Lichtdurchlass vermindert bzw. vermehrt wird, sondern auch, dass die auf die spiegelnden Abschnitte der einzelnen Lamellen fallenden Lichtstrahlen 12 in eine gewünschte Richtung, vorzugsweise gegen die Decke des zu beschattenden Raumes reflektiert werden können, wie das in Fig. 2 dargestellt ist.The result of this construction is that the lamellae cannot pivot by themselves about their axis, that is to say are fixed, but that when the angular gear 18 connected to the spindle is actuated by a motor or a crank handle (not shown), the nut 16 is moved up or down is moved, which in turn moves the push rod 13 in the same direction, whereby each lamella 1 is pivoted about its axis 4. This can not only achieve that the free space between the individual slats is reduced or enlarged and thus the light transmission is reduced or increased, but also that the light rays 12 falling on the reflecting sections of the individual slats in a desired direction, preferably against the Ceiling of the room to be shadowed can be reflected, as shown in Fig. 2.

Mit einer solchen Einrichtung lässt sich also der Einfall des Aussenlichtes nicht nur ganz oder teilweise abschirmen, sondern auch so steuern, dass in einem Raum ohne Oberlicht eine von der Decke ausgehende gleichmässig verteilte Helligkeit vorhanden ist, was für die verschiedenen, in der Einleitung genannten Räume ein wesentlicher Vorteil ist.With such a device, the incidence of the outside light can not only be partially or completely shielded, but also controlled so that in a room without a skylight one of there is evenly distributed brightness from the ceiling, which is a major advantage for the different rooms mentioned in the introduction.

In der Ausführungsform der Lamelle 1 nach den Fig. 4 und 5 ist der Mittelteil 5 von zwei gegeneinander geneigten und mit der übrigen Lamelle einstückig gefertigten Rippen 20 gebildet. Der im Querschnitt quadratische Einsatz 7a ist zwischen diese von ihm leicht gespreizten Rippen 20 gesteckt und wird von ihnen kraftschlüssig festgehalten. Der den Einsatz 7a überragende Achszapfen 7 ist - im Unterschied zum Beispiel nach den Fig. 1 bis 3 - exzentrisch angeordnet. Durch ein um 90°, 180° oder oder 270° gedrehtes Einstecken des Einsatzes 7a kann der Achszapfen 7 in eine Lage verschoben werden, in der seine geometrische Achse durch den Schwenkpunkt der Lamelle 1 oder nahe an diesem vorbei geht. Ist die Lamelle durch Funktionselemente wie die Spiegelplatte 6 stark asymmetrisch belastet, kann sie durch ein Verändern der Lage ihrer Achszapfen austariert werden, so dass einerseits der Mechanismus zum Verschwenken der Lamellen minimal und gleichmässig belastet wird und anderseits die an den Lamellen angreifende Schwerkraft ein schwaches Moment in Schliessrichtung auf sie ausübt. Weiter weist in dieser Ausführungsform der Lamelle 1 nicht nur der Teil 2 sondern auch der Teil 3 zwei Stege 1e und 1f als Befestigungsstellen für weitere Funktionselemente (wie die bereits erwähnte Spiegelplatte 6) auf. Somit kann die ganze Lamellenbreite vollständig oder nur teilweise mit Funktionselementen belegt werden.In the embodiment of the lamella 1 according to FIGS. 4 and 5, the central part 5 is formed by two ribs 20 inclined towards one another and made in one piece with the remaining lamella. The insert 7a, which has a square cross section, is inserted between these ribs 20, which are slightly spread by it, and is held by them in a force-locking manner. The axle journal 7 projecting beyond the insert 7a is arranged eccentrically, in contrast to the example according to FIGS. 1 to 3. By inserting the insert 7a rotated through 90 °, 180 ° or or 270 °, the axle pin 7 can be moved into a position in which its geometric axis passes through the pivot point of the lamella 1 or close to it. If the lamella is heavily asymmetrically loaded by functional elements such as the mirror plate 6, it can be balanced by changing the position of its axle journals so that on the one hand the mechanism for pivoting the lamella is loaded minimally and evenly and on the other hand the gravity acting on the lamellae creates a weak moment in the closing direction. Furthermore, in this embodiment of the lamella 1, not only the part 2 but also the part 3 has two webs 1e and 1f as fastening points for further functional elements (such as the mirror plate 6 already mentioned). This means that the entire slat width can be completely or only partially covered with functional elements.

Dem Längsrand 1c folgt eine Schwalbenschwanznut, in die eine Dichtlippe 21 formschlüssig eingesetzt ist. In einer Schwenkendlage (Fig. 5a) der Lamelle 1 kommt diese Dichtlippe 21 mit der benachbarten Lamelle 1 zur Anlage und schliesst einen allfälligen Lichtspalt ab. In der anderen Schwenkendlage (Fig. 5b) ist sie von aussen sichtbar und kann die Funktion eines in Breite und Farbe variablen Zierelementes haben. Der Schwenkwinkel zwischen beiden Endlagen beträgt zirka 180°, so dass beide Seiten der Lamelle 1 nach aussen oder gegen den abzudunkelnden Raum gewendet werden können.The longitudinal edge 1c is followed by a dovetail groove, into which a sealing lip 21 is inserted in a form-fitting manner. In a swivel end position (FIG. 5a) of the lamella 1, this sealing lip 21 comes into contact with the adjacent lamella 1 and closes off any light gap. In the other swivel end position (FIG. 5b) it is visible from the outside and can have the function of a decorative element that is variable in width and color. The swivel angle between the two end positions is approximately 180 °, so that both sides of the slat 1 can be turned outwards or against the room to be darkened.

Anstelle einer Spiegelplatte 6 kann eine Dünnschichtsonnenzelle als Funktionselement in die Stege 1e und 1f eingeschoben werden. Geeignet sind Dünnschichtsonnenzellen aus polykristallinen, auf einen metallischen Träger aufgedampften Halbleiterschichten aus Cadmiumsulfid, Cadmiumtellurid oder Kupfersulfid von etwa 10 bis 50 µm Stärke. Solche Sonnenzellen haben ein gutes Leistungsgewicht und sind vergleichweise billig herstellbar. Die gewonnene Energie kann bei oder in der Nähe der Beschattungseinrichtung gespeichert und zu ihrer elektrischen Steuerung verwendet werden. Damit entfallen aufwendige elektrische Installationen.Instead of a mirror plate 6, a thin-film solar cell can be inserted as a functional element in the webs 1e and 1f. Thin-film solar cells made of polycrystalline semiconductor layers made of cadmium sulfide, cadmium telluride or copper sulfide and having a thickness of about 10 to 50 μm are evaporated onto a metallic support. Such solar cells have a good power-to-weight ratio and are comparatively cheap to manufacture. The energy obtained can be stored at or near the shading device and used for its electrical control. This eliminates the need for complex electrical installations.

Als Funktionselement können auch schusshemmende Hart- oder Sintermetallstreifen zwischen die Stege 1e und 1f geschoben werden, wenn für den von der Beschattungseinrichtung abzudunkelnden Raum erhöhte Sicherheitsvorschriften bestehen.As a functional element, bullet-resistant hard or sintered metal strips can also be pushed between the webs 1e and 1f if there are increased safety regulations for the room to be darkened by the shading device.
