Definitions

  • the invention relates to an anti-glare device for light openings in interiors to be arranged in the latter, comprising translucent / translucent covering agents for at least partially covering the light openings and Changing the illuminance in the room as well as holding means to hold or carry the covering in the area of Light opening.
  • Glare protection devices are known in many forms such as Roller blinds, blinds, vertical slat curtains or curtains per se. These anti-glare devices unfold their Anti-glare effect by covering at least partially of the light openings.
  • There are various opaque ones as well as translucent or translucent materials such as plastics, sheets, curtain and pleated fabrics Glass fiber fabric, paper or parchment-like Materials, down to bast fabrics and wood are used.
  • They Common to these materials is that they are dependent essentially unchangeable from the light intensity Have transmittance for light. To a high To achieve glare protection, this must be as low as possible to get voted. Consequently, none can be completely transparent per se Find materials.
  • a disadvantage of the known anti-glare devices translucent covering means is essentially static Transmittance of the materials used, and regulation the illuminance in the rooms can therefore practically exclusively changing the size of the covered area of the light opening can be reached.
  • Of the Visual contact to the outside only remains within the uncovered Areas exist and focuses on these areas to achieve the desired anti-glare effect inevitably smaller with increasing light intensity represent future areas. With full coverage of the Light opening can still diffuse daylight into the Enter the room, but there is a line of sight to the outside usually completely lost.
  • the uncovered Areas i.e. the areas between the lamella elements, essentially uniform over the entire area the light opening are arranged.
  • the size of the covered Area is varied by inclining the slats, being a setting for an effective anti-glare effect in bright daylight or sunlight, if In general, only narrow stripes as uncovered areas allows. Only if the light intensities are not too high and none direct sunlight can therefore be a partial result Line of sight to the outside should be maintained, however is still severely restricted.
  • the invention is therefore based on the object of a glare protection device to create that depending on the Light intensity an automatic control of the illuminance the proportion of outside light in rooms with the same Size of the covered area of the light opening under simultaneous Maintains the line of sight to the outside.
  • Phototropic glasses that appear regularly in the specialist literature have been called photochromic glasses for decades, at least since the first half of the sixties, known. You can choose between mineral and organic Distinguish phototropic "glasses". Mineral phototropic Glasses are obtained by adding silver halides in the manufacture of the glass. You use it the effect that many crystalline chemical compounds, so also silver chloride and silver bromide, under the influence of light discolor and return to their initial state with increasing darkness to return. In the case of plastic glasses, the same effect by adding certain photoactive achieved organic substances. But it is also possible phototropic materials by means of surface coating, e.g. by vapor deposition using appropriate substances. The process for the production of phototropic or photochromic Materials are known and therefore do not need to be specified here are explained.
  • One effect depending on the light intensity have variable transmittance and thus a mechanical Adjustment of the covering means to change the irradiation quality, at least in wide areas, superfluous do.
  • the transparent properties of phototropic materials resemble those of glass, so that through the cover means the line of sight to the outside is maintained.
  • It will be adjustable and / or adjustable anti-glare agents of new quality created by changing the anti-glare effect by the light intensity, i.e. generally by the sunlight, is caused. This will make it possible to meet the requirements the above mentioned standardization like the DIN norm 5035 T7 and VO 270/90 EU.
  • phototropic foils together with translucent or transparent covering agents can easily be a phototropic anti-glare device be realized.
  • the Translucency of the cover means in contrast to cover means of the prior art can be significantly higher, since the Anti-glare effect essentially through the phototropic foils is achieved and the visual contact to the outside through the Covering agent should be kept straight through.
  • the material used for the masking agent one has a basic absorption of light, which is absorption of the phototropic material is superimposed. It can be used in to a certain extent the minimum and maximum absorption or Adjust the transmission of the anti-glare device.
  • the covering means even formed from phototropic material.
  • phototropic material thereby in particular surface designs such as Grids and Gradations, but also special shapes of the cover elements, which are not easily covered with a film could be realized.
  • the absorption is below another function of the layer thickness of the phototropic material, through which the light passes, with increasing Material thickness an increasing absorption takes place.
  • the material property of the phototropic Materials i.e. of the light / dark control area and the material thickness used, adjust.
  • the use of massive phototropic material for the masking leads to robust anti-glare devices, since there the phototropic Effect is not limited to the surface and therefore environmental influences and mechanical wear and tear that act naturally on the surface, only slight influence on the properties of the anti-glare device.
  • the cover from a fabric made of glass, acrylic or Plastic fibers with embedded or on the surface applied phototropic material.
  • the advantages of the phototropic material are shared combined those of the fabric.
  • Flexible phototropes are obtained Material that is especially rollable and compared have a greater thickness with phototropic films can.
  • material properties can be used like strength, flexibility / agility as well as a possibly desired stiffness become.
  • Such fabrics are particularly for use in phototropic Suitable for roller blinds. It is advantageous that even at full extended blinds maintain visual contact to the outside remains and by lightening and darkening the phototropic Material depending on the light intensity an automatic Control the illuminance in the room can.
  • Anti-glare device is provided, slats made of phototropic material to use as cover elements.
  • slats can preferably be vertical slat curtains or blinds can be created. It is advantageous also here that the visual contact to the outside regardless of the Inclination of the slats is retained.
  • Blinds or vertical slat curtains are the proportion of outside light the illuminance in the room or a glare protection regulated / achieved by inclining the slats.
  • the variable transmission of the phototropic material allows here also an automatic adjustment of this portion of the illuminance of the room depending on the light intensity. As a result, light is both attenuated here due to the manual inclination of the slats of the anti-glare device as well as by darkening or lightening of the phototropic material of the slats.
  • a preferred embodiment 5 of the invention shown in FIG. 1 seems prima facie, so superficial Not from a conventional anti-glare device to be distinguished in the form of a glare protection blind.
  • anti-glare device according to the invention, it has holding and Fastening means 1 on the one hand for fastening the device and on the other for carrying and holding cover means to serve.
  • a winding device 2 is in the Holding and fastening means 1 stored.
  • a pull chain 3 is provided to operate the Winding device 2, i.e. for pulling out and pulling in the covering means.
  • the covering means are made of phototropic material as roller blind 4 Executed material that up and by means of the winding device 2 can be unrolled.
  • Phototropic material can be used here in the form of phototropic plastic films, laminates or Fabrics are used.
  • the fabric itself can be made of glass, Acrylic or plastic fibers with embedded or on the Surface applied phototropic substances produced be. This ensures that the roller blind 4 is dependent discolored by the light intensity, i.e. with increasing Darkened light intensity and with decreasing light intensity brightens. In this way, variable light absorption is achieved and an automatic control of the illuminance in the Rooms depending on the light intensity.
  • Fig. 2 shows a further preferred embodiment 16 of the Invention in which the phototropic anti-glare as Vertical slats 11 are executed.
  • These are in one Guide rail 10 slidably and pivotally arranged.
  • Sliding device 12 can along the vertical slats 11 the guide rail 10 shifted and essentially evenly distributed over the length of the guide rail 10 to be ordered.
  • Within the guide rail 10 is furthermore a swivel device 14 is arranged with which the Vertical slats 11 can be pivoted or rotated. The swivel device 14 is actuated via the pull chain 15.
  • the vertical slats 11 made of phototropic / chrome material.
  • different can Materials such as foil laminates or fabrics are used. It is advantageous that the regulation of the external portion of the illuminance done in the room by two methods; on the one hand by manually turning / tilting the vertical slats, i.e. by changing the cover area of the Light opening, and secondly due to the variable Light attenuation through the phototropic material.
  • the object of the invention is not on the two above Embodiments limited.
  • Conventional blinds however Having phototropic lamellae represent another invention Embodiment, but due to the Similarity in use function and mode of action the vertical slat curtains according to the invention not in Detail needs to be described.
  • phototropic anti-glare curtains e.g. on the basis of glass fiber fabrics under the spirit of the invention.
  • An easy one technical implementation of the inventive concept lies in the Use of phototropic foils or disks, e.g. in front conventional window panes or skylights as anti-glare agents to be ordered.
  • Such structural components are e.g. realized in the form of lamellar structures, those in the top and / or side area of Light openings are arranged - necessarily - without direct in front of the opening with entry into the normal field of vision to be able to be moved.
  • the possibility of such slats to train or arrange according to the invention can be thus assign the inventive idea without difficulty.
