Definitions

  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • the liquid reservoir and the gas reservoir preferably have an elastic outer wall.
  • 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.
  • the window device 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.
  • 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.
  • 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.
  • 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.
  • the liquid can be formed from mercury, for example.
  • the liquid can be transparent and have a predetermined opacity, or it can be translucent, i. H. Be designed to diffuse light.
  • the window device according to the invention is explained below with reference to a preferred embodiment, which is shown in the figure of the drawing. It shows:
  • Fig.l a preferred embodiment of the window device according to the invention in a view from the front.
  • a gas and liquid-tight space is formed between two window panes 11, 12, the two window panes 11, 12 being spaced apart by 2 mm.
  • the gas- and liquid-tight space is partially filled with a light-absorbing liquid 13, which is activated by a pump, not shown, from a Liquid reservoir 15 can be introduced into the intermediate space in a metered manner.
  • a gas displaced by the liquid by the process of introducing liquid into the intermediate space escapes in this process into a gas reservoir 14 which is provided above the window panes 11, 12 and has an elastic outer wall.
  • the liquid 13 is transparent overall and has a light transparency of 50%. This has the effect, on the one hand, that rooms equipped with the window device according to the invention cannot be seen from the outside, but the outside scenery can be observed from the inside of the room.

Abstract

L'invention concerne un système de fenêtre comportant deux vitres (11, 12) intégrées dans un cadre, disposées parallèles l'une à l'autre, de manière à former au moins un espace intermédiaire. Un espace intérieur peut être obscurci du fait que l'espace intermédiaire entre les deux vitres (ou davantage) est étanche aux gaz et aux liquides et qu'il est prévu un dispositif permettant d'introduire un liquide (13) absorbant la lumière dans l'espace intermédiaire.
