Description

FENSTERVORRICHTUNG MIT VARIABLER TRANSPARENZ WINDOW DEVICE WITH VARIABLE TRANSPARENCY

Die Erfindung betrifft eine Fenstervorrichtung mit mindestens zwei in einen Fensterrahmen eingebundenen Fensterscheiben, die unter Bildung mindestens eines Zwischenraumes parallel zueinander angeordnet sind.The invention relates to a window device with at least two window panes integrated in a window frame, which are arranged parallel to one another to form at least one intermediate space.

Herkömmliche Fenstervorrichtungen der eingangs genannten Art weisen gegenüber Fenstern, die von einer einzelnen Fensterscheibe gebildet sind, den Vorteil auf, daß sie auf Grund der geringen Wärmeleitfähigkeit des Zwischenraums eine erhöhte Wärmeisolation gegenüber der Außenluft aufweisen. Insbesondere jedoch wenn diese Fenstervorrichtungen sehr groß ausgestaltet sind oder an schwer zugänglichen Stellen vorgesehen sind, sind derartige Fenstervorrichtungen nur schwer zu verdunkeln, wenn das Innere eines Raumes vor Sonnenlicht geschützt werden soll, wozu meistens externe Jalousien oder Gardinen verwendet werden. Diese Einrichtungen weisen darüber hinaus den Nachteil auf, daß bei einem Verdunkeln des Fensters die Sicht nach außen mindestens teilweise obstruiert ist.Conventional window devices of the type mentioned at the outset have the advantage over windows which are formed from a single window pane that they have increased thermal insulation from the outside air because of the low thermal conductivity of the intermediate space. But especially if this Window devices are very large or are provided in places that are difficult to access, such window devices are difficult to darken if the interior of a room is to be protected from sunlight, for which purpose external blinds or curtains are mostly used. These devices also have the disadvantage that the view to the outside is at least partially obstructed when the window is darkened.

Aufgabe der Erfindung ist es, eine Fenstervorrichtung zu schaffen, die auf einfache Weise effektiv verdunkelbar ist, wobei auch bei einer verdunkelten Fenstervorrichtung eine Sicht nach außen zumindest prinzipiell ermöglicht ist.The object of the invention is to provide a window device which can be effectively darkened in a simple manner, with a view to the outside being made possible at least in principle even with a darkened window device.

Für eine Vorrichtung der eingangs genannten Art wird diese Aufgabe dadurch gelöst, daß der Zwischenraum zwischen den mindestens zwei Scheiben gas- und flüssigkeitsdicht ausgebildet ist und eine Einrichtung vorgesehen ist, mittels derer eine Licht-absorbierende Flüssigkeit in den Zwischenraum einbringbar ist.For a device of the type mentioned in the introduction, this object is achieved in that the space between the at least two disks is made gas and liquid-tight and a device is provided by means of which a light-absorbing liquid can be introduced into the space.

Bevorzugte Ausführungsformen der Erfindung sind Gegenstand der Unteransprüche .Preferred embodiments of the invention are the subject of the dependent claims.

Bei der erfindungsgemäßen Fenstervorrichtung wird durch die Merkmalskombination, daß der Zwischenraum zwischen den mindestens zwei Scheiben gas- und flüssigkeitsdicht ausgebildet ist und desweiteren eine Einrichtung vorgesehen ist, mittels derer eine Licht-absorbierende Flüssigkeit in den Zwischenraum einbringbar ist, erreicht, daß die erfindungsgemäße Fenstervorrichtung insgesamt mittels der gezielt steuerbar in den Zwischenraum einbringbaren Licht-absorbierenden Flüssigkeit verdunkelbar ist. Dies hat zum einen den Vorteil, daß im dem Fenster nahen Bereich des Innenraumes der Fenstervorrichtung platzraubende Jalousien oder Gardinen entbehrlich sind, und es wird durch die Möglichkeit der Wahl der spezifischen optischen Eigenschaften bestimmter Licht-absorbierender Flüssigkeiten erreicht, daß die Fenstervorrichtung durch die spezielle Wahl einer Licht-absorbierenden Flüssigkeit entweder durchsichtig, d. h. Licht-transparent ist und gleichwohl eine vorgegebene Opazität aufweist, oder lediglich durchscheinend, d. h. eine Lichtdiffusion bewirkend, gestaltet ist, wie dies beispielsweise bei Latex-haltigen, milchig trüben Flüssigkeiten der Fall ist.In the window device according to the invention, the combination of features that the space between the at least two panes is gas-tight and liquid-tight and furthermore a device is provided by means of which a light-absorbing liquid can be introduced into the space, that the The window device according to the invention as a whole can be darkened by means of the light-absorbing liquid which can be introduced into the intermediate space in a controlled manner. On the one hand, this has the advantage that space-consuming blinds or curtains are dispensable in the area of the interior of the window device near the window, and it is achieved by the possibility of choosing the specific optical properties of certain light-absorbing liquids that the window device can be selected a light-absorbing liquid is either transparent, ie light-transparent and nevertheless has a predetermined opacity, or is only designed to be translucent, ie to cause light diffusion, as is the case, for example, with latex-containing, milky, cloudy liquids.

Gemäß einer bevorzugten Ausführungsform der erfindungsgemäßen Fenstervorrichtung enthält die Einrichtung, mittels derer eine Licht-absorbierende Flüssigkeit in den Zwischenraum einbringbar ist, mindestens ein Flüssigkeitsreservoir und ein Gasreservoir, die jeweils mit dem Zwischenraum kommunizierend verbunden sind. Dadurch wird erreicht, daß die Menge der in den Zwischenraum einzubringenden Licht-absorbierenden Flüssigkeit leicht steuerbar ist. Das Flüssigkeitsreservoir und das Gasreservoir weisen zu diesem Zweck vorzugsweise eine elastische Außenwandung auf.According to a preferred embodiment of the window device according to the invention, the device by means of which a light-absorbing liquid can be introduced into the intermediate space contains at least one liquid reservoir and one gas reservoir, each of which is communicatively connected to the intermediate space. This ensures that the amount of light-absorbing liquid to be introduced into the intermediate space is easily controllable. For this purpose, the liquid reservoir and the gas reservoir preferably have an elastic outer wall.

Die Einrichtung, mittels derer eine Licht-absorbierende Flüssigkeit in den Zwischenraum einbringbar ist, enthält vorzugsweise eine elektrisch steuerbare Pumpe, mit der die Flüssigkeit in den Zwischenraum pumpbar ist. Die Pumpe kann dabei so steuerbar sein, daß nur ein Teilbereich der Fenster durch Licht-absorbierende Flüssigkeit verdunkelt ist. Durch diese Möglichkeit ist die Gesamtintensität des durch die Fenstervorrichtung einfallenden Lichtes sehr einfach und sehr genau steuerbar.The device, by means of which a light-absorbing liquid can be introduced into the intermediate space, contains preferably an electrically controllable pump with which the liquid can be pumped into the intermediate space. The pump can be controlled so that only a portion of the window is darkened by light-absorbing liquid. With this possibility, the total intensity of the light incident through the window device can be controlled very easily and very precisely.

Gemäß einer wichtigen Ausführungsform der erfindungsgemäßen Fenstervorrichtung sind drei parallele Fensterscheiben mit zwei Zwischenräumen vorgesehen, die über zwei unterschiedliche Einrichtungen mit Licht-absorbierender Flüssigkeit befüllbar sind. Dadurch wird erreicht, daß die Gesamtintensitat der durch die erfindungsgemäße Fenstervorrichtung einfallenden Lichtstrahlen noch besser steuerbar ist. Insbesondere wird dadurch erreicht, daß vorherbestimmbare Bereiche der Fenstervorrichtung eine noch niedrigere Lichttransparenz als die übrigen Bereiche aufweisen. Insbesondere sind Ausführungsformen denkbar, bei denen die in einen ersten Zwischenraum einbringbare Flüssigkeit durchsichtig und gleichwohl opak ist und die in den anderen Zwischenraum einbringbare Flüssigkeit lediglich durchscheinend ist, d. h. Licht-diffusionierend wirkt.According to an important embodiment of the window device according to the invention, three parallel window panes with two gaps are provided, which can be filled with light-absorbing liquid via two different devices. It is thereby achieved that the total intensity of the light rays incident through the window device according to the invention can be controlled even better. In particular, it is achieved that predeterminable areas of the window device have an even lower light transparency than the other areas. In particular, embodiments are conceivable in which the liquid which can be introduced into a first intermediate space is transparent and nevertheless opaque and the liquid which can be introduced into the other intermediate space is only translucent, i.e. H. Diffuses light.

Die Transparenz der in den mindestens einen Zwischenraum der erfindungsgemäßen Fenstervorrichtung einbringbaren Flüssigkeit beträgt vorzugsweise zwischen 90 % und 10 %. Weist die erfindungsgemäße Fenstervorrichtung zwei oder mehr Zwischenräume auf, so sind diese vorzugsweise jeweils mit unterschiedlich stark Licht-absorbierenden Flüssigkeiten befüllbar.The transparency of the liquid which can be introduced into the at least one intermediate space of the window device according to the invention is preferably between 90% and 10%. If the window device according to the invention has two or more gaps, these are preferably each Can be filled with differently strong light-absorbing liquids.

Die Transparenz der Licht-absorbierenden Flüssigkeit der erfindungsgemäßen Fenstervorrichtung kann gemäß einer bevorzugten Ausführungsform 0 % betragen. Die Flüssigkeit ist in diesem Fall vollständig Licht-undurchlässig, d. h. es findet eine vollständige Reflexion oder Absorption von einfallendem Licht statt. Die Flüssigkeit kann in diesem Fall beispielsweise aus Quecksilber gebildet sein. Alternativ kann die Flüssigkeit durchsichtig sein und eine vorgegebene Opazität aufweisen, oder sie kann durchscheinend, d. h. Licht-diffusionierend ausgebildet sein.According to a preferred embodiment, the transparency of the light-absorbing liquid of the window device according to the invention can be 0%. The liquid in this case is completely opaque, i.e. H. there is complete reflection or absorption of incident light. In this case, the liquid can be formed from mercury, for example. Alternatively, the liquid can be transparent and have a predetermined opacity, or it can be translucent, i. H. Be designed to diffuse light.
