Definitions
- the invention relates to an anti-glare device for attachment on the room side Light openings comprising transparent covering means for at least partial covering of the light openings, the or each covering means being provided with a phototropic material and holding means for holding or carrying the covering means in the area of the light openings.
- Glare protection devices are known in many forms, such as roller blinds, blinds, vertical lamella curtains or curtains themselves. Unfold these anti-glare devices their anti-glare effect by at least partially covering the light openings. There come different opaque as well as translucent or translucent Materials such as plastics, sheet metal, curtain and pleated fabrics, coated glass fiber fabrics, paper or parchment-like materials, right down to bast fabrics and wood for use. All these materials have in common that they are dependent on the light intensity have essentially unchangeable transmittance for light. To one To achieve a high anti-glare effect, this must be chosen as low as possible. Hence cannot use materials that are completely transparent per se.
- a disadvantage of the known anti-glare devices with translucent covering means the essentially static transmittance of the materials used, and regulation The illuminance in the rooms can therefore practically only be above changing the size of the covered area of the light opening can be achieved.
- the Visual contact to the outside only remains and is concentrated within the uncovered areas focus on these areas that help achieve the desired anti-glare effect increasing light intensity inevitably represent ever smaller areas. With complete Covering the light opening can still cause diffuse daylight in the Enter space, but the line of sight to the outside is usually completely lost.
- a glare protection device of the generic type is known from DE 3514656.
- the disclosed device ensures glare protection against incident light Light and on the other hand a line of sight to the outside.
- an adjustment of the covering means in particular for the individual regulation of the proportion of outside light and the adjustment of the direction of light, is not possible because the device as Rolling shutters that can be rolled up on the outside of the window and are therefore only movable is trained.
- the object of the invention is therefore to create an anti-glare device, which fulfills all legal regulations for anti-glare devices at the same time, namely Glare protection, permanent line of sight to the outside and an adjustability of the device.
- the cover means as a lamella cover and with facilities for individual regulation of the proportion of outside light and adjustment the direction of light from one level over the entire area of the light openings is adjustable in an inclined position.
- the anti-glare device according to the invention with a slat cover it is possible that the visual contact to the outside regardless of the inclination the slats is retained.
- conventional blinds or vertical slat curtains becomes the outside light component of the illuminance in the room or a glare protection regulated / achieved by inclining the slats.
- a darkening or lightening of the materials which means a change the transmission or absorption goes hand in hand.
- the transparent properties of phototropic Materials are similar to those of glass, so that the line of sight is visible through the covering means remains outside.
- there are adjustable and / or adjustable anti-glare agents of new quality are provided.
- the phototropic material is as on the cover means attachable film formed.
- the cover means attachable film formed.
- the translucency is expedient the cover means in contrast to cover means of the prior art considerably may be higher since the anti-glare effect is essentially due to the phototropic films is achieved and the visual contact to the outside is maintained straight through the covering means should stay.
- the material used for the covering agent one obtains in this way a basic absorption of the light that overlaps the absorption of the phototropic material becomes. In this way, the minimum and maximum absorption or Adjust the transmission of the anti-glare device.
- the type of line of sight to the outside is essentially due to the optical properties of the used for the cover Material determined.
- the cover means are themselves made of phototropic material educated. As a result, surface designs such as Grids and Gradations, but also special shapes of the cover elements, which are not easy could be covered with a film, realizable. Furthermore, the absorption is below another function of the layer thickness of the phototropic material through which the light passes, with increasing absorption taking place with increasing material thickness.
- the desired control range for the illuminance in the rooms can be determined by the Material property of the phototropic material, i.e. of the light / dark control area and the material thickness used, adjust.
- the use of solid phototropic material for the cover means leads to more robust anti-glare devices, since there the phototropic Effect is not limited to the surface and thus environmental and mechanical Wear and tear, which naturally affect the surface, have little influence on the properties of the anti-glare device.
- the covering means can be made of a fabric made of glass, acrylic or plastic fibers with embedded or on the surface applied phototropic material.
- Flexible phototropes are obtained Material that is especially rollable and a higher compared to phototropic films Can have thickness.
- material properties can be used such as strength, flexibility / agility as well as a desired stiffness to be influenced.
- Fig. 1 shows a preferred embodiment 16 of the invention, in which the phototropic Anti-glare means are designed as vertical slats 11. These are in a guide rail 10 slidably and pivotally arranged. By means of an inside of the guide rail 10 arranged displacement device 12 can along the vertical slats 11 the guide rail 10 shifted and substantially uniform over the length of the Guide rail 10 can be arranged distributed.
- the shifting device 12, which e.g. by a cable pull system can be realized is actuated by a pull cable 13.
- a pivot device 14 is arranged with the vertical slats 11 can be pivoted or rotated. The swivel device 14 is actuated via the pull chain 15.
- the vertical slats 11 are made of phototropic / chrome material. Different materials can be used such as foil laminates or fabrics are used.
- the fabric itself can be made of glass, Acrylic or plastic fibers with embedded or applied phototropic fibers Substances. This ensures that the slats are dependent discolor from the light intensity, i.e. darken with increasing light intensity and lighten with decreasing light intensity. How to achieve variable light absorption and an automatic regulation of the illuminance in the rooms depending on the Light intensity.
- the regulation of the external portion of the illuminance in the room is done by two methods; on the one hand through manual twisting / inclination the vertical slats, i.e. by changing the cover area of the light opening, and on the other hand additionally due to the variable light attenuation by the phototropic material.
- the object of the invention is not limited to the above embodiment.
- Conventional Blinds which, however, have phototropic horizontal slats, represent a further one according to the invention Embodiment represents, but because of the similarity in the use function and the mode of operation of the vertical slat curtains according to the invention need not be described in detail.
- phototropic anti-glare curtains e.g. on the basis of glass fiber fabrics fall under the protective principles of the invention.
