Definitions
- the invention relates to a roller shutter with articulated interconnected opaque and translucent shutter elements, which are mounted on a Winding shaft are wound up.
- Such roller shutter armor for example, from the German patent application DE-OS 16 59 604 or French utility model FR 22 43 606 known.
- These blinds allow essentially three different positions.
- the first Position exists in the fully wound on a winding shaft shutters, in the the light inlet opening or the window is released.
- In a part lowered position change translucent and opaque Shutter elements and thus allow only partial darkening, even if the shutter extends over the full window height.
- the shutter can now still be lowered to the third position.
- the transparent shutter elements in roughlyd impermeable shutter elements, so that the opaque Blind elements lie close to each other and thus give a full darkening is.
- a disadvantage of these roller shutter is the fact that the alternately opaque and translucent shutter elements especially in direct Solar radiation from outside in the room will produce unwanted light streaks and it In addition, through the translucent shutter elements still through Dazzling can come.
- the object of the invention is therefore to provide a roller shutter of the aforementioned Genus to create, with the dazzling and unwanted stripe pattern in the Interior spaces can be largely avoided.
- the translucent Roller shutter elements are at least partially formed diffusely scattering.
- diffuse scattering trained shutter elements diffuse the incoming light into different angle ranges.
- the glare is greatly reduced and the disturbing stripe patterns inside the room, as they are especially at Computer workstations are very disturbing, can be avoided.

- diffuse scattering materials can also be used with the roughened ones Combine surface.
- the diffusely diffusing materials are easy to process and are particularly robust. With regard to the avoidance of a dazzling effect and a view from inside to outside for the viewer, one will have to compromise in practice, because if the scattering effect is too low, the glare behavior is less good and, on the other hand, with high scattering effect, the transparency will increasingly deteriorate. In practice, therefore, one will adjust the scattering effect so that one still has an at least shadowy view.
- the spreading of the translucent, diffusely scattering shutter elements is designed such that at parallel light irradiation, the transmitted light has an angular intensity distribution, the following table satisfies: angle Light intensity (referring to the irradiation direction) (based on the maximum light intensity in the direction of irradiation, 0 °, assumed as 100%) 8 ° 10% -50% 20 ° 2% -20% 45 ° less than 5%
- a glare in the direction of irradiation can be avoided in particular well if the luminance coefficient ⁇ of the translucent, diffusely scattering shutter elements with parallel light irradiation in the direction of irradiation is less than 10 cd / m 2 Lx.

Abstract
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 shutter elements, which are mounted on a Winding shaft are 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 Aufnahmekammem der profilierten undurchlässigen Rolladenelemente ein, sodaß die lichtundurchlässigen Rolladenelemente satt aneinanderliegen und damit eine volle Verdunkelung gegeben ist.Such roller shutter armor, for example, from the German patent application DE-OS 16 59 604 or French utility model FR 22 43 606 known. These blinds allow essentially three different positions. The first Position exists in the fully wound on a winding shaft shutters, in the the light inlet opening or the window is released. In a part lowered position change translucent and opaque Shutter elements and thus allow only partial darkening, even if the shutter extends over the full window height. The shutter can now still be lowered to the third position. In this position, the transparent shutter elements in Aufnahmekammem the profiled impermeable shutter elements, so that the opaque Blind elements lie close to each other and thus give a full darkening 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 is the fact that the alternately opaque and translucent shutter elements especially in direct Solar radiation from outside in the room will produce unwanted light streaks and it In addition, through the translucent shutter elements still through Dazzling can come.
Aus der EP-A-0 367 212 ist ein gattungsgemäßer Rolladenpanzer bekannt, bei dem auf den ansonsten vollständig durchsichtigen Rolladenelementen eine makroskopische lichtbrechende Oberflächenstruktur vorgesehen ist. From EP-A-0 367 212 a generic roller shutter is known in which on the otherwise completely transparent shutter elements a macroscopic refractive surface structure is provided.
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 of the aforementioned Genus to create, with the dazzling and unwanted stripe pattern in the Interior spaces 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 formed diffusely scattering.
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 glass clear shutter elements share the invention diffuse scattering trained shutter elements diffuse the incoming light into different angle ranges. Thus, the glare is greatly reduced and the disturbing stripe patterns inside the room, as they are especially at Computer workstations are very disturbing, 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 diffusely scattering effect can be achieved in various ways. For example, it is possible to avoid a diffusely scattering material in itself, for example, in the material itself scattering inclusions, particles or Pigmentations can be provided. Also a training similar to one Milk glass is possible. However, glass is not a preferred material here. Much more should preferably be used for plastics, with particular acrylic glass as Base material is suitable. Such plastics are easy to get in the desired Produce profiling and by mixing to the desired degree of diffusion to adjust. They are also sturdy, cost effective and they can also be used in the If necessary, flexible design, what a winding up the roller shutter on 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.Apart from diffusing materials, it is also possible to even with crystal-clear materials a light-scattering effect through a roughened Surface to achieve. The surface structure can, for example, by a Roughness can be achieved, as it is also achieved when sandblasting glass. Of course, diffuse scattering materials can also be used with the roughened ones 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:
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.A glare in the direction of irradiation can be avoided in particular well if the luminance coefficient κ of the translucent, diffusely scattering shutter elements with parallel light irradiation in the direction of irradiation is less than 10 cd / m 2 Lx.
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 incoming light arises when the translucent shutter elements at least partially preferably consist of crystal clear material and to achieve the light scattering roughened on at least 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 through the transparent Bring elements into the room. However, as already mentioned, not directed but diffused scattered. For this purpose, it is preferably provided that the entire (angular integrated) light transmission through the translucent, diffusely diffusing Roller shutter elements over 60%, preferably more than 85%. In practice one becomes 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 inventive design of the roller shutter can alternately translucent and opaque shutter elements are used without that disturbing in direct sunlight in the room interior Strip pictures is coming.
Weitere Vorteile und Einzelheiten der Erfindung werden anhand der nachfolgenden
Figurenbeschreibung näher erläutert.
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 shown in Figs. 1 and 2 consists of alternately
opaque 1 and translucent 2 shutter elements that over their
hook-
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 the glare in the interior and in direct sunlight
to avoid disturbing stripe images is now provided according to the invention,
that the
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 in a fully closed position, in the

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
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 formed according to the invention
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:
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 effect in the direction of irradiation, the material of the
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 be achieved not only by scattering material or
by incorporating scattering particles inside the material, as with the
previously described embodiments was the case. Rather, it is too
possible to use crystal clear material and to roughen its
