Description

Die Erfindung betrifft einen Rolladenpanzer mit gelenkig miteinander verbundenen lichtundurchlässigen und lichtdurchlässigen Rolladenelementen, die auf einer Wickelwelle aufwickelbar sind.The invention relates to a roller shutter with articulated interconnected opaque and translucent roller shutter elements on a Winding shaft can be wound up.

Derartige Rolladenpanzer sind beispielsweise aus der deutschen Offenlegungsschrift DE-OS 16 59 604 oder dem französischen Gebrauchsmuster FR 22 43 606 bekannt. Diese Rolläden erlauben im wesentlichen drei verschiedene Stellungen. Die erste Stellung besteht im vollständig auf einer Wickelwelle aufgewickelten Rolladen, bei der die Lichteintrittsöffnung bzw. das Fenster freigegeben ist. In einer teilweise herabgelassenen Stellung wechseln lichtdurchlässige und lichtundurchlässige Rolladenelemente ab und erlauben somit eine nur teilweise Verdunkelung, selbst wenn sich der Rolladen über die vollständige Fensterhöhe erstreckt. Der Rolladen kann nun noch ganz in die dritte Stellung herabgelassen werden. In dieser Stellung treten die durchsichtigen Rolladenelemente in Aufnahmekammern der profilierten undurchlässigen Rolladenelemente ein, sodaß die lichtundurchlässigen Rolladenelemente satt aneinanderliegen und damit eine volle Verdunkelung gegeben ist.Such roller shutter curtains are, for example, from the German published application DE-OS 16 59 604 or the French utility model FR 22 43 606 known. These shutters essentially allow three different positions. The first The position consists in the roller shutters completely wound on a winding shaft the light entry opening or the window is released. In part lowered position change translucent and opaque Roller shutter elements and thus allow only partial darkening, even if the roller shutter extends across the full height of the window. The roller shutter can now can still be lowered completely into the third position. In this position the transparent roller shutter elements in receiving chambers of the profiled impermeable shutter elements so that the opaque Roller shutter elements lie snugly against each other and thus give a full blackout is.

Nachteilig an diesen Rolladenpanzern ist die Tatsache, daß die abwechselnd lichtundurchlässigen und lichtdurchlässigen Rolladenelemente vor allem bei direkter Sonnenbestrahlung von außen im Raum unerwünschte Lichtstreifen erzeugen und es außerdem durch die lichtdurchlässigen Rolladenelemente hindurch immer noch zu Blendungen kommen kann.A disadvantage of these roller shutter curtains is the fact that they alternate opaque and translucent roller shutter elements, especially with direct Sun exposure from outside create unwanted light strips in the room and it also still through through the translucent roller shutter elements Glare can come.

Aufgabe der Erfindung ist es daher, einen Rolladenpanzer der eingangs genannten Gattung zu schaffen, mit dem Blendungen und unerwünschte Streifenmuster im Rauminneren weitgehend vermieden werden können.The object of the invention is therefore to provide a roller shutter curtain of the type mentioned To create genus with the glare and unwanted stripe pattern in the The interior of the room can be largely avoided.

Erfindungsgemäß wird dies dadurch erreicht, daß die lichtdurchlässigen Rolladenelemente zumindest teilweise diffus streuend ausgebildet sind.According to the invention this is achieved in that the translucent Roller shutter elements are at least partially diffusely formed.

Im Gegensatz zu normalen glasklaren Rolladenelementen teilen die erfindungsgemäß diffus streuend ausgebildeten Rolladenelemente das einfallende Licht diffus in unterschiedliche Winkelbereiche auf. Damit wird die Blendwirkung stark reduziert und die störenden Streifenmuster im Inneren des Raumes, wie sie insbesondere bei Bildschirmarbeitsplätzen stark störend sind, können vermieden werden.In contrast to normal, crystal-clear roller shutter elements, they share the invention Roller shutter elements designed to be diffusely scattering the incident light different angular ranges. This greatly reduces the glare and the annoying stripe patterns inside the room, as they are especially in VDU workplaces are very annoying can be avoided.

Die diffus streuende Wirkung kann auf verschiedene Arten erzielt werden. Beispielsweise ist es möglich, ein in sich diffus streuendes Material zu vermeiden, wobei beispielsweise im Material selbst streuende Einschlüsse, Partikel oder Pigmentierungen vorgesehen sein können. Auch eine Ausbildung ähnlich einem Milchglas ist möglich. Allerdings ist Glas hier kein bevorzugtes Material. Vielmehr sollen bevorzugt Kunststoffe zum Einsatz kommen, wobei sich besonders Acrylglas als Basismaterial eignet. Solche Kunststoffe lassen sich leicht in der gewünschten Profilierung herstellen und durch Abmischung auf den gewünschten Diffusionsgrad einstellen. Sie sind außerdem robust, kostengünstig und außerdem können sie im Bedarfsfall flexibel ausgebildet werden, was ein Aufwickeln des Rolladenpanzers auf der Wickelwelle erleichtert.The diffuse scattering effect can be achieved in different ways. For example, it is possible to avoid a diffusely scattering material, where, for example, inclusions, particles or scattering in the material itself Pigmentations can be provided. Training similar to one Frosted glass is possible. However, glass is not a preferred material here. Much more Plastics should preferably be used, with acrylic glass in particular Base material is suitable. Such plastics can be easily in the desired Create profiling and by mixing to the desired degree of diffusion to adjust. They are also robust, inexpensive and they can also be used in If necessary, be trained flexibly, resulting in a winding of the roller shutter curtain the winding shaft easier.

Abgesehen von in sich diffus streuenden Materialien besteht auch die Möglichkeit, selbst bei glasklaren Materialien eine lichtstreuende Wirkung durch eine aufgerauhte Oberfläche zu erzielen. Die Oberflächenstruktur kann dabei beispielsweise durch eine Rauhigkeit erzielt werden, wie sie auch beim Sandstrahlen von Glas erreicht wird. Natürlich lassen sich auch in sich diffus streuende Materialien mit der aufgerauhten Oberfläche kombinieren.In addition to diffusely scattering materials, there is also the option of even with crystal-clear materials, a light-scattering effect due to a roughened To achieve surface. The surface structure can be, for example, by a Roughness can be achieved, as is also achieved when sandblasting glass. Of course, materials that are diffusely scattered can also be roughened Combine surface.

Die in sich diffus streuenden Materialien lassen sich leicht verarbeiten und sind besonders robust. Im Hinblick auf die Vermeidung einer Blendwirkung und eine von innen nach außen erzielte Durchsicht für den Betrachter wird man in der Praxis einen Kompromiß eingehen müssen, weil bei zu geringer Streuwirkung das Blendverhalten weniger gut ist und andererseits bei hoher Streuwirkung sich die Durchsicht zunehmend verschlechtert. In der Praxis wird man daher die Streuwirkung so einstellen, daß man noch eine zumindest schemenhafte Durchsicht hat. Dazu ist vorteilhaft vorgesehen, daß der Streugrad der lichtdurchlässigen, diffus streuenden Rolladenelemente derart gestaltet ist, daß bei Parallelleichteinstrahlung das durchgelassene Licht eine winkelmäßige Intensitätsverteilung aufweist, die folgender Tabelle genügt: Winkel Lichtintensität (bezogen auf die Einstrahlungsrichtung) (bezogen auf die als 100% angesetzte maximale Lichtintensität in Einstrahlungsrichtung, 0°) 8° 10%-50% 20° 2%-20% 45° weniger als 5% The diffusely scattering materials are easy to process and are particularly robust. With regard to the avoidance of a glare effect and a view achieved from the inside out for the viewer, one will have to make a compromise in practice, because the glare behavior is less good when the scattering effect is too low and, on the other hand, the view deteriorates increasingly when the scattering effect is too low. In practice, therefore, the spreading effect will be adjusted so that you still have an at least vague view. For this purpose, it is advantageously provided that the degree of diffusion of the translucent, diffusely scattering roller shutter elements is designed in such a way that, when exposed to parallel light, the transmitted light has an angular intensity distribution, which is sufficient in the following table: angle Light intensity (related to the direction of irradiation) (based on the 100% maximum light intensity in the direction of irradiation, 0 °) 8 ° 10% -50% 20 ° 2% -20% 45 ° less than 5%

Eine Blendung in Einstrahlungsrichtung läßt sich insbesondere dann gut vermeiden, wenn der Leuchtdichtekoeffizient κ der lichtdurchlässigen, diffus streuenden Rolladenelemente bei Parallellichteinstrahlung in Einstrahlungsrichtung unter 10 cd/m2 Lx liegt.Glare in the direction of irradiation can be avoided particularly well if the luminance coefficient κ of the translucent, diffusely scattering roller shutter elements is less than 10 cd / m 2 Lx with parallel light irradiation in the direction of irradiation.

Eine annehmbare Durchsicht von innen bei guter Aufstreuung des einfallenden Lichtes ergibt sich, wenn die lichtdurchlässigen Rolladenelemente zumindest teilweise aus vorzugsweise glasklarem Material bestehen und zum Erzielen der Lichtstreuung zumindest einseitig aufgerauht sind.An acceptable view from the inside with good scattering of the incident light results if the translucent roller shutter elements at least partially preferably crystal clear material and to achieve light scattering are roughened at least on one side.

Insgesamt möchte man natürlich möglichst viel Licht durch die durchsichtigen Elemente in den Raum bringen. Allerdings, wie bereits erwähnt, nicht gerichtet sondern diffus aufgestreut. Dazu ist bevorzugt vorgesehen, daß der gesamte (winkelmäßig aufintegrierte) Lichttransmissionsgrad durch die lichtdurchlässigen, diffus streuenden Rolladenelemente über 60%, vorzugsweise über 85% liegt. In der Praxis wird man Werte zwischen 80 und 90% erzielen.Overall, of course you want as much light as possible through the transparent Bring elements into the room. However, as already mentioned, not directed but scattered diffusely. For this purpose, it is preferably provided that the entire (angular integrated) light transmittance through the translucent, diffusely scattering Roller shutter elements is over 60%, preferably over 85%. In practice you will Achieve values between 80 and 90%.

Mit der erfindungsgemäßen Ausbildung des Rolladenpanzers können abwechselnd lichtdurchlässige und lichtundurchlässige Rolladenelemente eingesetzt werden, ohne daß es bei direkter Sonnenbestrahlung im Rauminneren zu störenden Streifenabbildungen kommt.With the design of the roller shutter curtain according to the invention can alternately translucent and opaque roller shutter elements can be used without that it can be disruptive when exposed to direct sunlight inside the room Streak pictures is coming.

Weitere Vorteile und Einzelheiten der Erfindung werden anhand der nachfolgenden Figurenbeschreibung näher erläutert.

    • Further advantages and details of the invention are explained in more detail with reference to the following description of the figures.

    • Der in den Fig. 1 und 2 dargestellte Rolladenpanzer besteht abwechselnd aus lichtundurchlässigen 1 und lichtdurchlässigen 2 Rolladenelementen, die über ihre hakenförmigen Endbereiche 3 gelenkig miteinander verbunden sind. Damit kann der Rolladenpanzer wie üblich oben auf einer nicht dargestellten Wickelwelle aufgewickelt und hochgezogen werden. Der Rolladenpanzer kann dabei in üblicher Weise links und rechts in vertikalen Führungsschienen, die seitlich neben der Lichteintrittsöffnung, beispielsweise eines Fensters eines Gebäudes, verlaufen, geführt sein. Der Hohlraum 4 in den lichtundurchlässigen Rolladenelementen kann auch ausgeschäumt sein, wie es ebenfalls Stand der Technik ist.The roller shutter curtain shown in FIGS. 1 and 2 consists of alternately opaque 1 and translucent 2 shutter elements over their hook-shaped end regions 3 are hinged together. So that the Roller shutter curtain, as usual, wound up on a winding shaft, not shown and be pulled up. The roller shutter can be left and in the usual way on the right in vertical guide rails, which are to the side of the light entry opening, for example, a window of a building, run, be guided. The cavity 4 in the opaque roller shutter elements can also be foamed, such as it is also state of the art.

    Um die Blendung im Innenraum zu reduzieren und bei direkter Sonneneinstrahlung störende Streifenabbildungen zu vermeiden, ist nun erfindungsgemäß vorgesehen, daß die lichtdurchlässigen Rolladenelemente 2 diffus streuend ausgebildet sind. Bei den in den Fig. 1 und 2 dargestellten Ausführungsbeispielen bestehen die lichtundurchlässigen Rolladenelemente 2 jeweils vollständig aus transparentem, diffus streuendem Material. Besonders eignet sich dazu Kunststoff und hier wiederum insbesondere Acrylglas. Die lichtdurchlässigen Rolladenelemente 2 können somit auf einfache Weise einstückig ausgebildet sein, wobei auch die hakenförmigen Endbereiche direkt angeformt sind. Aus lichttechnischer Sicht führt die Ausbildung aus diffus streuendem Material, welches beispielsweise einen milchweißen Eindruck erweckt, dazu, daß die einfallenden Lichtstrahlen in unterschiedlichste Raumrichtungen ausgestreut werden, wodurch die Leuchtdichte in einem bestimmten Raumwinkelbereich abnimmt. Damit wird die Blendwirkung verringert und außerdem störende Streifenbildungen vermieden. Insgesamt kann aber doch erreicht werden, daß der gesamte winkelmäßig aufintegrierte Lichttransmissionsgrad hoch ist, er kann vorzugsweise über 60% und insbesondere sogar über 85% liegen.To reduce glare in the interior and in direct sunlight to avoid disruptive strip images is now provided according to the invention, that the translucent roller shutter elements 2 are designed to be diffusely scattering. At The embodiments shown in FIGS. 1 and 2 exist opaque roller shutter elements 2 each completely made of transparent, diffuse scattering material. Plastic is particularly suitable for this and here again especially acrylic glass. The translucent roller shutter elements 2 can thus be formed in one piece in a simple manner, the hook-shaped also End areas are molded directly. From a lighting point of view, the training carries out diffusely scattering material, which for example has a milky white impression awakens that the incident light rays in different spatial directions are scattered, thereby reducing the luminance in a particular Solid angle range decreases. This reduces the glare and also annoying banding avoided. Overall, however, can be achieved that the total angularly integrated light transmittance is high, it can preferably over 60% and in particular even over 85%.

    Die Fig. 2 zeigt den Rolladenpanzer in einer vollständig geschlossenen Stellung, in der die lichtdurchlässigen Rolladenelemente 2 in Kammern 5 der lichtundurchlässigen Rolladenelemente 1 aufgenommen sind. Die lichtundurchlässigen Rolladenelemente liegen satt aneinander, sodaß kein Licht durch den Rolladenpanzer durchtreten kann.Fig. 2 shows the roller shutter curtain in a fully closed position, in the the translucent shutter elements 2 in chambers 5 of the opaque Roller shutter elements 1 are included. The opaque roller shutter elements lie close together so that no light can pass through the roller shutter curtain.

    Die lichtdurchlässigen Rolladenelemente 2 weisen einen mittleren verdichteten Bereich 9 auf, der im geschlossenen Zustand (Fig. 2) eine gute Führung der angrenzenden lichtundurchlässigen Rolladenelemente 1 erlaubt, In der Stellung gemäß Fig. 1 ist dennoch ein Spiel 10 vorhanden, das das Aufwickeln erleichtert.The translucent roller shutter elements 2 have a central compressed area 9 on, in the closed state (Fig. 2) good guidance of the adjacent opaque roller shutter elements 1 allowed, in the position shown in FIG. 1 nevertheless, a game 10 is present, which makes winding up easier.

    Die Fig. 3 zeigt, wie ein erfindungsgemäß ausgebildetes lichtdurchlässiges Rolladenelemente 2 einen einfallenden Parallellichtstrahl 6 aufstreut. Die relative Lichtintensität in einem bestimmten Winkelbereich α kann durch einen kleinen Detektor 7 gemessen werden, der die Lichtintensität eines austretenden Lichtstrahles 8 (bzw. genauer gesagt eines engen Lichtstrahlenbündels) erfaßt. Damit ist es möglich, die intensitätsmäßige Winkelverteilung der austretenden Lichtstrahlen bezüglich der Lichteinfallsrichtung zu erfassen. Einen guten Kompromiß zwischen der Durchsicht durch die lichtdurchlässigen Rolladenelemente und einer guten Blendwirkung erzielt man, wenn die lichtdurchlässigen Rolladenelemente zumindest teilweise diffus streuend ausgebildet sind.Fig. 3 shows how a translucent designed according to the invention Roller shutter elements 2 scatter an incident parallel light beam 6. The relative Light intensity in a certain angular range α can be measured by a small detector 7 can be measured, which the light intensity of an emerging light beam 8 (or more precisely, a narrow beam of light) is detected. This makes it possible to intensity-related angular distribution of the emerging light rays with respect to the To capture the direction of light incidence. A good compromise between looking through achieved by the translucent roller shutter elements and a good glare one if the translucent roller shutter elements are at least partially diffuse are scattered.

    Besonders bevorzugt ist vorgesehen, daß der Streugrad der lichtdurchlässigen, diffus streuenden Rolladenelemente derart gestaltet ist, daß bei Parallelleichteinstrahlung das durchgelassene Licht eine winkelmäßige Intensitätsverteilung aufweist, die folgender Tabelle genügt: Winkel Lichtintensität (bezogen auf die Einstrahlungsrichtung) (bezogen auf die als 100% angesetzte maximale Lichtintensität in Einstrahlungsrichtung, 0°) 8° etwa 25% 20° etwa 10% 45° weniger als 1% It is particularly preferably provided that the degree of diffusion of the translucent, diffusely scattering roller shutter elements is designed in such a way that the light transmitted through has an angular intensity distribution when exposed to parallel light, which is sufficient in the following table: angle Light intensity (based on the direction of irradiation) (based on the 100% maximum light intensity in the direction of irradiation, 0 °) 8 ° about 25% 20 ° about 10% 45 ° less than 1%

    Um die Blendwirkung in Einstrahlungsrichtung zu vermeiden, ist günstigerweise das Material der lichtdurchlässigen Rolladenelemente 2 so gewählt, daß der Leuchtdichtekoeffizient κ unter 10 cd/m2 Lx liegt.In order to avoid the glare in the direction of irradiation, the material of the translucent roller shutter elements 2 is advantageously chosen so that the luminance coefficient κ is below 10 cd / m 2 Lx.

    Eine lichtstreuende Wirkung kann man nicht nur durch in sich streuendes Material bzw. durch Einschluß streuender Partikel im Inneren des Materials erzielen, wie dies bei den bisher beschriebenen Ausführungsbeispielen der Fall war. Vielmehr ist es auch möglich, glasklares Material zu verwenden und dessen Oberfläche 11 aufzurauhen, wie dies in Fig. 4 gezeigt ist.A light-scattering effect can not only be achieved by scattering material or by including scattering particles inside the material, as is the case with The previously described exemplary embodiments were the case. Rather, it is possible to use crystal-clear material and to roughen its surface 11, as shown in FIG. 4.
