Description
Die Erfindung bezieht sich auf eine Blendschutzvorrichtung zur raumseitigen Anbringung an Lichtöffnungen umfassend transparente Abdeckmittel zum mindestens teilweisen Abdecken der Lichtöffnungen, wobei das oder jedes Abdeckmittel mit einem phototropen Material versehen ist, sowie Haltemittel zum Halten bzw. Tragen der Abdeckmittel im Bereich der Lichtöffnungen.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.
Bekannt sind Blendschutzvorrichtungen in vielerlei Formen wie Rollos, Jalousien, Vertikal-Lamellen-Vorhängen oder auch Vorhängen an sich. Diese Blendschutzvorrichtungen entfalten ihre Blendschutzwirkung durch das mindestens teilweise Abdecken der Lichtöffnungen. Dabei kommen verschiedene lichtundurchlässige als auch lichtdurchlässige bzw. -scheinende Materialien wie Kunststoffe, Bleche, Vorhang- und Plisseestoffe, beschichtete Glasfasergewebe, papier- bzw. pergamentähnliche Materialien, bis hin zu Bastgeweben und Holz zum Einsatz. Allen diesen Materialien ist gemeinsam, daß sie einen in Abhängigkeit von der Lichtintensität im wesentlichen unveränderlichen Transmissionsgrad für Licht aufweisen. Um eine hohe Blendschutzwirkung zu erreichen, muß dieser möglichst gering gewählt werden. Folglich können keine an sich völlig transparenten Materialien Verwendung finden.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.
Nachteilig bei den bekannten Blendschutzvorrichtungen mit transluzenten Abdeckmitteln ist der im wesentlichen statische Transmissionsgrad der verwendeten Materialien, und eine Regulierung der Beleuchtungsstärke in den Räumen kann deshalb praktisch ausschließlich über ein Verändern der Größe der abgedeckten Fläche der Lichtöffnung erreicht werden. Der Sichtkontakt nach außen bleibt nur innerhalb der unabgedeckten Flächen bestehen und konzentriert sich auf diese Bereiche, die zum Erreichen der angestrebten Blendschutzwirkung mit steigender Lichtintensität zwangsläufig immer kleiner werdende Flächen darstellen. Bei vollständiger Abdeckung der Lichtöffnung kann zwar immer noch diffuses Tageslicht in den Raum eintreten, die Sichtverbindung nach außen hin geht aber in der Regel ganz verloren.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.
Üblicherweise und sogar nach gesetzlichen Vorschriften - mechanische - verstellbare Jalousien und Vertikal-Lamellen-Vorhänge tragen diesen Problemen insofern Rechnung, daß die unabgedeckten Flächen, d.h. die Flächen zwischen den Lamellenelementen, im wesentlichen gleichmäßig über den gesamten Bereich der Lichtöffnung angeordnet sind. Die Größe der abgedeckten Fläche wird durch Schrägstellen der Lamellen variiert, wobei eine Einstellung für eine effektive Blendschutzwirkung bei hellem Tageslicht oder Sonnenlichteinfall, wenn überhaupt, nur noch schmale Streifen als unabgedeckte Flächen zuläßt. Nur bei nicht zu hohen Lichtintensitäten und keinem direkten Sonnenlichteinfall kann folglich eine teilweise Sichtverbindung nach außen hin beibehalten werden, die aber trotzdem stark eingeschränkt ist.Usually and even according to legal regulations - mechanical - adjustable blinds and vertical slat curtains take these problems into account in that the uncovered areas, i.e. the areas between the lamella elements, essentially are evenly arranged over the entire area of the light opening. The size of the covered area is varied by tilting the slats, making an adjustment for an effective anti-glare effect in bright daylight or sunlight, if at all, only narrow stripes are allowed as uncovered areas. Only with not too high Light intensities and no direct sunlight can consequently be a partial one Line of sight to the outside should be maintained, but it is still severely restricted is.
Inzwischen fordert die Standardisierung der Beleuchtungsintensität für Arbeitsplätze mit Bildschirmgeräten - in Deutschland beispielsweise durch DIN-Norm 5035 T7 sowie im EU-Bereich durch die VO 270/90 EU geregelt - einerseits sehr geringe Leuchtdichten zur Begrenzung der Reflexblendung auf dem Bildschirm und andererseits bei Abschirm- und Blendschutzmaßnahmen die Beibehaltung der Sichtverbindung nach außen. Diese gegensätzlichen Forderungen sind mit herkömmlichen Blendschutzvorrichtungen nicht erfüllbar.In the meantime, the standardization of lighting intensity for workstations with display devices is required - In Germany, for example, through DIN standard 5035 T7 and in the EU area regulated by VO 270/90 EU - on the one hand, very low luminance limits the reflex glare on the screen and on the other hand with shielding and glare protection measures maintaining the line of sight to the outside. These opposite Demands cannot be met with conventional anti-glare devices.
So ist aus der DE 3514656 eine Blendschutzvorrichtung der gattungsgemäßen Art bekannt. Zwar gewährleistet die offenbarte Vorrichtung einerseits einen Blendschutz gegen einfallendes Licht und andererseits eine Sichtverbindung nach außen. Es besteht jedoch der Nachteil, daß eine Verstellung der Abdeckmittel, insbesondere zur individuellen Regelung des Außenlichtanteils und der Einstellung der Lichtrichtung, nicht möglich ist, da die Vorrichtung als außen am Fenster anzubringender, aufrollbarer und damit lediglich verschiebbarer Rolladen ausgebildet ist.A glare protection device of the generic type is known from DE 3514656. On the one hand, the disclosed device ensures glare protection against incident light Light and on the other hand a line of sight to the outside. However, there is the disadvantage that 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.
Der Erfindung liegt deshalb die Aufgabe zugrunde, eine Blendschutzvorrichtung zu schaffen, die alle gesetzlichen Vorschriften für Blendschutzvorrichtungen gleichzeitig erfüllt, nämlich Blendschutz, permanente Sichtverbindung nach außen und eine Verstellbarkeit der Vorrichtung.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.
Diese Aufgabe wird erfindungsgemäß in Verbindung mit den Merkmalen der Blendschutzvorrichtung der eingangs genannten Art dadurch erreicht, daß die Abdeckmittel als Lamellen-Abdeckung und mit Einrichtungen zur individuellen Regelung des Außenlichtanteils und Einstellung der Lichtrichtung aus einer Ebene heraus über die gesamte Fläche der Lichtöffnungen in eine Schrägstellung verstellbar ausgebildet ist.This object is achieved in accordance with the features of the anti-glare device of the type mentioned in that 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.
Durch die Ausführungsform der erfindungsgemäßen Blendschutzvorrichtung mit einer Lamellen-Abdeckung ist es möglich, daß der Sichtkontakt nach außen unabhängig von der Neigung der Lamellen erhalten bleibt. Wie bei herkömmlichen Jalousien bzw. Vertikal-Lamellen-Vorhängen wird der Außenlichtanteil der Beleuchtungsstärke im Raum bzw. ein Blendschutz durch Schrägstellen der Lamellen geregelt/erreicht. In Abhängigkeit von der Lichtintensität erfolgt auch ein Eindunkeln oder Aufhellen der Materialien, womit eine Veränderung der Transmission bzw. Absorption einhergeht. Die transparenten Eigenschaften von phototropen Materialien ähneln denen von Glas, so daß durch die Abdeckmittel hindurch die Sichtverbindung nach außen erhalten bleibt. Es werden somit ein- und/oder verstellbare Blendschutzmittel neuer Qualität geschaffen. Eine Lichtdämpfung erfolgt hier folglich sowohl durch die manuelle Schrägstellung der Lamellen der Blendschutzvorrichtung als auch durch das Eindunkeln bzw. Aufhellen des phototropen Materials der Lamellen. Damit wird es möglich, alle Anforderungen der oben erwähnten Standardisierung wie der DIN-Norm 5035 T7 und die VO 270/90 EU gleichzeitig zu erfüllen.Due to the embodiment of 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. As with 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. Depending on the light intensity there is also 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. Thus there are adjustable and / or adjustable anti-glare agents of new quality. Light is attenuated here by both manual inclination of the slats of the anti-glare device as well as by darkening or lightening the phototropic material of the slats. It will make it possible for everyone Requirements of the above mentioned standardization like the DIN standard 5035 T7 and the To comply with VO 270/90 EU at the same time.
In einer bevorzugten Ausführungsform ist das phototrope Material als auf den Abdeckmitteln anbringbare Folie ausgebildet. Durch die Verwendung von phototropen Folien zusammen mit transluzenten bzw. transparenten Abdeckmitteln kann auf einfache Weise eine phototrope Blendschutzvorrichtung verwirklicht werden. Zweckmäßigerweise wird dabei die Transluzenz der Abdeckmittel im Gegensatz zu Abdeckmitteln des Standes der Technik erheblich höher sein können, da die Blendschutzwirkung im wesentlichen durch die phototropen Folien erzielt wird und der Sichtkontakt nach außen durch die Abdeckmittel hindurch gerade erhalten bleiben soll. Je nach Wahl des für das Abdeckmittel verwendeten Materials erhält man so eine Grundabsorption des Lichtes, der die Absorption des phototropen Materials überlagert wird. Damit läßt sich in einem gewissen Maß die minimale und maximale Absorption bzw. Transmission der Blendschutzvorrichtung einstellen. Die Art der Sichtverbindung nach außen wird dabei im wesentlichen durch die optischen Eigenschaften des für die Abdeckmittel verwendeten Materials bestimmt.In a preferred embodiment, the phototropic material is as on the cover means attachable film formed. By using phototropic foils together with Translucent or transparent covering agents can easily be phototropic Anti-glare device can be realized. 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. Depending on the choice of 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.
Bei einer vorteilhaften Weiterbildung sind die Abdeckmittel selbst aus phototropem Material ausgebildet. Dadurch sind insbesondere Oberflächengestaltungen wie z.B. Rasterungen und Abstufungen, aber auch spezielle Formgebungen der Abdeckelemente, die nicht ohne weiteres mit einer Folie überzogen werden könnten, realisierbar. Weiterhin ist die Absorption unter anderem eine Funktion der Schichtdicke des phototropen Materials, durch das das Licht hindurchtritt, wobei mit zunehmender Materialdicke eine zunehmende Absorption stattfindet. Der gewünschte Regelbereich für die Beleuchtungsstärke in den Räumen läßt sich durch die Materialeigenschaft des phototropen Materials, d.h. des Hell-/Dunkelregelbereiches und die verwendete Materialstärke, einstellen. Die Verwendung von massivem phototropem Material für die Abdeckmittel führt zu robusteren Blendschutzvorrichtungen, da dort der phototrope Effekt nicht auf die Oberfläche beschränkt ist und somit Umwelteinflüsse und mechanische Abnutzung bzw. Verschleiß, die naturgemäß auf die Oberfläche einwirken, nur geringen Einfluß auf die Eigenschaften der Blendschutzvorrichtung haben.In an advantageous development, 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.
Nach einer anderen bevorzugten Weiterbildung der Erfindung können die Abdeckmittel aus einem Gewebe aus Glas-, Acryl- oder Kunststoffasern mit eingelagertem oder auf die Oberfläche aufgebrachtem phototropem Material ausgebildet sein. Hierbei werden die Vorteile des phototropen Materials mit denen des Gewebes kombiniert. Man erhält flexibles phototropes Material, das insbesondere auch rollbar ist und verglichen mit phototropen Folien eine höhere Dicke aufweisen kann. Je nach Faserstärke und Gewebeart können dabei Materialeigenschaften wie Festigkeit, Biegsamkeit/Beweglichkeit sowie eine unter Umständen gewünschte Steifheit beeinflußt werden.According to another preferred development of the invention, 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. Here the advantages of phototropic material combined with those of the fabric. Flexible phototropes are obtained Material that is especially rollable and a higher compared to phototropic films Can have thickness. Depending on the fiber thickness and type of fabric, material properties can be used such as strength, flexibility / agility as well as a desired stiffness to be influenced.

Fig. 1 zeigt eine bevorzugte Ausführungsform 16 der Erfindung, bei der die phototropen
Blendschutzmittel als Vertikal-Lamellen 11 ausgeführt sind. Diese sind in einer Führungsschiene
10 verschiebbar und schwenkbar angeordnet. Mittels einer im Inneren der Führungsschiene
10 angeordneten Verschiebeeinrichtung 12 können die Vertikal-Lamellen 11 entlang
der Führungsschiene 10 verschoben und im wesentlichen gleichmäßig über die Länge der
Führungsschiene 10 verteilt angeordnet werden. Die Verschiebeeinrichtung 12, die z.B. durch
ein Seilzugsystem verwirklicht werden kann, wird durch ein Zugseil 13 betätigt. Innerhalb der
Führungsschiene 10 ist weiterhin eine Schwenkeinrichtung 14 angeordnet, mit der die Vertikal-Lamellen
11 geschwenkt bzw. verdreht werden können. Die Schwenkeinrichtung 14 wird
über die Zugkette 15 betätigt. Aufbau und Funktion von Vertikal-Lamellen-Vorhängen sind
grundsätzlich bekannt, so daß es hierfür keiner weiteren Ausführungen bedarf. Die Vertikal-Lamellen
11 sind aus phototropem / -chromem Material. Dabei können verschiedene Materialien
wie Folienlaminate oder Gewebe eingesetzt werden. Das Gewebe selbst kann aus Glas-,
Acryl- oder Kunststoffasern mit eingelagerten oder auf der Oberfläche aufgebrachten phototropen
Substanzen hergestellt sein. Dadurch erreicht man, daß sich die Lamellen in Abhängigkeit
von der Lichtintensität verfärben, d.h. bei zunehmender Lichtintensität verdunkeln und
bei abnehmender Lichtintensität aufhellen. So erreicht man eine variable Lichtabsorption und
eine automatische Regelung der Beleuchtungsstärke in den Räumen in Abhängigkeit von der
Lichtintensität. Vorteilhaft ist, daß die Regelung des Außenanteils der Beleuchtungsstärke in
dem Raum durch zwei Verfahren erfolgt; zum einen durch das manuelle Verdrehen/Schrägstellen
der Vertikal-Lamellen, d.h. durch ein Verändern der Abdeckfläche der Lichtöffnung,
und zum anderen zusätzlich infolge der variablen Lichtdämpfung durch das phototrope Material.Fig. 1 shows a
Der Gegenstand der Erfindung ist nicht auf die obige Ausführungsform begrenzt. Herkömmliche Jalousien, die jedoch phototrope Horizontal-Lamellen aufweisen, stellen eine weitere erfindungsgemäße Ausführungsform dar, die aber aufgrund der Ähnlichkeit in der Gebrauchsfunktion und der Wirkungsweise zu den erfindungsgemäßen Vertikal-Lamellen-Vorhängen nicht in Detail beschrieben werden braucht. Auch phototrope Blendschutzvorhänge, z.B. auf der Basis von Glasfasergeweben, fallen unter den Schutzgedanken der Erfindung. 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. Also phototropic anti-glare curtains, e.g. on the basis of glass fiber fabrics fall under the protective principles of the invention.
Dieses gilt übrigens auch im Hinblick auf den sich nach den bisherigen Erkenntnissen und Absichten für den Erfindungsgedanken abzeichnenden Haupteinsatzbereich, wonach die Blendschutzmittel im Inneren von Büro-, Wohnräumen oder sonstigen abgeschlossenen Aufenthaltsstätten angeordnet sein sollen. Es versteht sich jedoch für den Fachmann auf dem einschlägigem Fachgebiet, also der Blendschutztechnik, daß die erfindungsgemäßen Blendschutzvorrichtungen auch an den Außenseiten der Lichtöffnungen vorgesehen werden können. Natürlich müssen dann besondere Umstände, die sich z.B. durch den Witterungseinfluß ergeben könnten, berücksichtigt werden. Die daraus resultierenden Anforderungen sind aber von herkömmlichen Blendschutzvorrichtungen her bekannt. Aufgrund der im wesentlichen transparenten Blendschutzmittel sind allerdings z.B. der Reinigung wie auch der Schallentwicklung infolge Windangriffs oder ähnlichen Aspekten mehr Bedeutung zuzumessen als bei relativ geschütztem Einsatz im Inneren von Gebäuden.Incidentally, this also applies with regard to the current knowledge and Intentions for the main area of application, according to the invention, according to which the Anti-glare agent in the interior of offices, living rooms or other locked places should be arranged. However, it is understood by those skilled in the relevant Technical field, that is, anti-glare technology, that the anti-glare devices according to the invention can also be provided on the outside of the light openings. Of course, special circumstances, e.g. due to the weather could result. The resulting requirements are, however known from conventional anti-glare devices.
