Definitions

  • the present invention relates to a device for illuminating rooms, especially in buildings.
  • a device of this genus is out DE-A 31 03 715 known.
  • a light well for basement windows is disclosed in the interior of which one or two mirror surfaces are mounted so that the daylight is reflected into the space behind the basement window.
  • One of these mirror surfaces stands diagonally in the ground in front of the basement window. If there are two mirror surfaces, then the second mirror surface is at ground level and disposed obliquely above said first mirror surface.
  • the first disadvantage of this device can be called the fact that the surrounding earth or other pourable material rests directly on the outside of said mirror surfaces. This not only makes extremely high demands on the strength of the mirror surfaces but this also represents a danger to the functionality of the mirror surfaces themselves. Because the vertical edge portions of the mirror surfaces are apparently unprotected, so that, for example, moisture can reach mirroring front side of the mirror surfaces, which can lead to the destruction of the mirrorability of said areas. If you want to make changes to this device or must, then you must remove the voltage applied to the mirror surfaces earth, etc. In addition, the luminous efficacy of such a device is relatively low, because the light deflection in the basement, only two mutually opposed mirror surfaces available stand. This means, for example, that those light rays are lost, which of the mirror surfaces against the non-mirrored side portions of the light shaft be reflected.
  • One of the objects of the present invention is to obviate the above and other disadvantages of the prior art.

Since the shaft 2 at the in Fig. 1 shown device is relatively long, the length of the housing 3 is greater than the width thereof. Consequently, the mentioned and vertical edges of the side walls 71 and 72 of the housing 3, which are interconnected by the transverse wall 6 of the housing 3, are longer than the horizontally extending edges 37 of the side walls 71 and 72 Fig. 1 , in which the present device is shown in a vertical section, only the rear side wall 72 of the housing 3 is visible.

Description

Die vorliegende Erfindung betrifft eine Einrichtung zur Ausleuchtung von Räumen, insbesondere in Gebäuden.The present invention relates to a device for illuminating rooms, especially in buildings.

Eine Einrichtung dieser Gattung ist aus DE-A 31 03 715 bekannt. In diesem Dokument des Standes der Technik ist ein Lichtschacht für Untergeschossfenster offenbart, in dessen Inneren eine oder zwei Spiegelflächen so angebracht sind, dass das Tageslicht in den Raum hinter dem Untergeschossfenster reflektiert wird. Eine von diesen Spiegelflächen steht im Erdreich schräg vor dem Untergeschossfenster. Wenn es zwei Spiegelflächen gibt, dann ist die zweite Spiegelfläche ebenerdig und schräg oberhalb der genannten ersten Spiegelfläche angeordnet.A device of this genus is out DE-A 31 03 715 known. In this prior art document, a light well for basement windows is disclosed in the interior of which one or two mirror surfaces are mounted so that the daylight is reflected into the space behind the basement window. One of these mirror surfaces stands diagonally in the ground in front of the basement window. If there are two mirror surfaces, then the second mirror surface is at ground level and disposed obliquely above said first mirror surface.

Als ersten Nachteil dieser Einrichtung kann man die Tatsache nennen, dass die umliegende Erde oder sonstiges schüttfähiges Material unmittelbar an der Aussenseite der genannten Spiegelflächen aufliegt. Dies stellt nicht nur ausserordentlich hohe Anforderungen an die Festigkeit der Spiegelflächen sondern dies stellt auch eine Gefahr für die Funktionstüchtigkeit der Spiegelflächen selbst dar. Denn die vertikal verlaufenden Randpartien der Spiegelflächen sind offenbar ungeschützt, sodass beispielsweise Feuchtigkeit bis zu spiegelnden Frontseite der Spiegelflächen gelangen kann, was zur Zerstörung der Spiegelfähigkeit der genannten Flächen führen kann. Wenn man Änderungen an dieser Einrichtung durchführen will bzw. muss, dann muss man die an den Spiegelflächen anliegende Erde entfernen usw. Ausserdem ist die Lichtausbeute einer solchen Einrichtung verhältnismässig niedrig, weil zur Lichtumlenkung in das Untergeschoss, bloss zwei sich einander gegenüber stehenden Spiegelflächen zur Verfügung stehen. Dies bedeutet beispielsweise, dass jene Lichtstrahlen verloren gehen, welche von den Spiegelflächen gegen die nicht verspiegelten Seitenbereiche des Lichtschachtes reflektiert werden.The first disadvantage of this device can be called the fact that the surrounding earth or other pourable material rests directly on the outside of said mirror surfaces. This not only makes extremely high demands on the strength of the mirror surfaces but this also represents a danger to the functionality of the mirror surfaces themselves. Because the vertical edge portions of the mirror surfaces are apparently unprotected, so that, for example, moisture can reach mirroring front side of the mirror surfaces, which can lead to the destruction of the mirrorability of said areas. If you want to make changes to this device or must, then you must remove the voltage applied to the mirror surfaces earth, etc. In addition, the luminous efficacy of such a device is relatively low, because the light deflection in the basement, only two mutually opposed mirror surfaces available stand. This means, for example, that those light rays are lost, which of the mirror surfaces against the non-mirrored side portions of the light shaft be reflected.

Eine der Aufgaben der vorliegenden Erfindung ist, die genannten sowie noch weitere Nachteile des Standes der Technik behoben werden können.One of the objects of the present invention is to obviate the above and other disadvantages of the prior art.

Diese Aufgabe wird bei der Einrichtung der eingangs genannten Gattung erfindungsgemäss so gelöst, wie dies im kennzeichnenden Teil des Patentanspruchs 1 definiert ist.This object is achieved according to the invention in the device of the type mentioned above, as defined in the characterizing part of patent claim 1.

Fig. 1 zeigt eine erste Ausführung der vorliegenden Einrichtung, welche insbesondere zur Ausleuchtung von Tiefgeschossräumen, beispielsweise in Bauwerken, dienen kann. In Fig. 1 ist ein Ausschnitt aus einer Wand 5 schematisch dargestellt, welche einen der Bestandteile eines Bauwerkes, beispielsweise eines Hauses, darstellen kann. Dieser Ausschnitt aus einer Wand 5 befindet sich unterhalb des Niveaus des Erdreiches 4. Im dargestellten Ausschnitt aus der Bauwerkwand 5 ist eine Öffnung 8 ausgeführt, in welcher normalerweise ein Kellerfenster eingesetzt sein kann. Die Gebäudeöffnung 8 kann viereckförmig, rund, oval oder dgl. sein. Im dargestellten Fall ist die Wandöffnung 8 rechteckförmig und sie liegt ebenfalls unterhalb des Niveaus des Erdreiches 4. Die längeren Seiten des Rechteckes verlaufen im dargestellten Fall horizontal. Hinter der Aussparung 8, d.h. an der Innenseite der Gebäudewand 5, befindet sich ein zu beleuchtender Raum 42. Fig. 1 shows a first embodiment of the present device, which can be used in particular for the illumination of Tiefgeschossräumen, for example in buildings. In Fig. 1 is a section of a wall 5 is shown schematically, which may represent one of the components of a building, such as a house. This section of a wall 5 is located below the level of the soil 4. In the illustrated section of the building wall 5, an opening 8 is executed, in which normally a basement window can be used. The building opening 8 may be quadrangular, round, oval or the like. In the case shown, the wall opening 8 is rectangular and it is also below the level of the soil 4. The longer sides of the rectangle are horizontal in the illustrated case. Behind the recess 8, that is, on the inside of the building wall 5, there is a room to be illuminated 42nd

Zwischen dem oberen Niveau des Erdreiches 4 und dem Bereich der Gebäudeöffnung 8 erstreckt sich ein Schacht 2. Die vorliegende Einrichtung umfasst ein Gehäuse 3, welches sich im genannten Schacht 2 befindet und welches die äussere Begrenzung des Schachtes 2 gegenüber dem Erdreich 4 darstellt. Das Gehäuse 3 kann aus einem üblichen Baumaterial, wie z.B. aus Beton sein. Ein solches Gehäuse 3 kann auch als ein vorfabriziertes Element vorliegen, welches der Aussenfläche 14 der Hauswand 5 so zugeordnet ist, dass sich die Wandöffnung 8 im Bereich dieses Gehäuses 3 befindet.Between the upper level of the soil 4 and the area of the building opening 8 extends a shaft 2. The present device comprises a housing 3, which is located in said shaft 2 and which represents the outer boundary of the shaft 2 with respect to the ground 4. The housing 3 may be made of a conventional building material, such as concrete. Such a housing 3 can also be present as a prefabricated element, which is associated with the outer surface 14 of the building wall 5 such that the wall opening 8 is located in the region of this housing 3.

Im in Fig. 1 dargestellten Fall hat der Grundkörper des Gehäuses 3 einen U-förmigen Querschnitt, sodass der Grundkörper zwei seitliche Wände 71 und 72 und eine die einen Kanten dieser Seitenwände 71 und 72 verbindende Querwand 6 aufweist. Die Längsachse eines solchen Gehäuses 3 verläuft im wesentlichen vertikal, sodass auch die Wände 6, 71 und 72 des Gehäuses 3 vertikal verlaufen. Da der Schacht 2 bei der in Fig. 1 dargestellten Einrichtung verhältnismässig lang ist, ist die Länge des Gehäuses 3 grösser als die Breite desselben. Folglich sind die erwähnten und vertikal verlaufenden Kanten der Seitenwände 71 und 72 des Gehäuses 3, welche durch die Querwand 6 des Gehäuses 3 miteinander verbunden sind, länger als die horizontal verlaufenden Kanten 37 der Seitenwände 71 und 72. In Fig. 1, in der die vorliegende Einrichtung in einem vertikalen Schnitt dargestellt ist, ist nur die hinten liegende Seitenwand 72 des Gehäuses 3 ersichtlich.Im in Fig. 1 In the case illustrated, the base body of the housing 3 has a U-shaped cross-section, so that the base body has two lateral walls 71 and 72 and a transverse wall 6 which connects one edge of these side walls 71 and 72. The longitudinal axis of such a housing 3 extends substantially vertically, so that the walls 6, 71 and 72 of the housing 3 extend vertically. Since the shaft 2 at the in Fig. 1 shown device is relatively long, the length of the housing 3 is greater than the width thereof. Consequently, the mentioned and vertical edges of the side walls 71 and 72 of the housing 3, which are interconnected by the transverse wall 6 of the housing 3, are longer than the horizontally extending edges 37 of the side walls 71 and 72 Fig. 1 , in which the present device is shown in a vertical section, only the rear side wall 72 of the housing 3 is visible.

Das U-förmige Gehäuse 3 weist Endbereiche 38 und 40 auf, welche unter anderem die horizontal verlaufenden Kanten 37 der Gehäuseseitenwände 71 und 72 umfassen. Der eine dieser Stirnbereiche 38 liegt oben etwa auf dem Niveau des Erdreiches 4, dieser Stirnbereich 38 verläuft praktisch horizontal und er ist offen. Der gegenüberliegende Stirnbereich 40 des Gehäuses 3 befindet sich tief im Erdreich 4, und zwar zumindest im Bereich der unteren Kante 181 der Gebäudeöffnung 8. Diese untere Stirnseite 40 des Gehäuses 3 ist zweckmässigerweise offen um zu ermöglichen, dass das allfällig in das Gehäuse 3 eingedrungene Wasser im Erdreich 4 versickern kann. Diese untere Stirnseite 40 des Gehäuses 3 kann jedoch auch geschlossen sein, und zwar beispielsweise mit Hilfe einer unteren Stirnwand 13 (Fig. 6), welche mit den übrigen Wänden 6, 71 und 72 des Gehäuses 3 einstückig ist. Als Abschluss der unteren Stirnöffnung 40 im Gehäuse 3 kann jedoch auch ein Deckel dienen, welcher einer an sich bekannten Art sein kann. Ein solcher Deckel erlaubt das Versickern von Wasser aus dem Gehäuse 3 in das Erdreich 4. Zugleich kann dieser Deckel, bei einer entsprechenden optisch ansprechenden Ausführung desselben, auch als Sichtblende dienen, damit man den Erdboden 4 durch die Oeffnung 8 in der Gebäudewand 5 nicht sehen kann.The U-shaped housing 3 has end portions 38 and 40, which include, among other things, the horizontally extending edges 37 of the housing side walls 71 and 72. The one of these end portions 38 is above about at the level of the soil 4, this end portion 38 extends virtually horizontally and he is open. The opposite end region 40 of the housing 3 is located deep in the ground 4, specifically at least in the area of the lower edge 181 of the building opening 8. This lower end face 40 of the housing 3 is expediently open in order to allow any water which has penetrated into the housing 3 in the ground 4 can seep. However, this lower end face 40 of the housing 3 may also be closed, for example with the aid of a lower end wall 13 (FIG. Fig. 6 ), which is integral with the other walls 6, 71 and 72 of the housing 3. As a conclusion of the lower end opening 40 in the housing 3, however, can also serve a lid, which may be of a known type. Such a cover allows the seepage of water from the housing 3 in the soil 4. At the same time, this cover, with a corresponding visually appealing design of the same, also serve as a screen, so you do not see the ground 4 through the opening 8 in the building wall 5 can.

Ein solches Gehäuse 3 ist über die freien und vertikal verlaufenden Kanten 9 der Seitenwände 71 und 72 desselben der Aussenfläche 14 der Gebäudewand 5 in einer an sich bekannten Weise zugeordnet. Unter Umständen genügt sogar nur der Druck der Erde 4 auf die Aussenseite der vertikal verlaufenden Querwand 6 des Gehäuses 3, um dieses Gehäuse 3 in einer gewünschten Lage gegenüber der Gebäudeöffnung 8 zu halten. Die Wände 6, 71 und 72 des Gehäuses 3 definieren drei Wände des Schachtes 2. Die vierte Wand des Schachtes 2 ist durch den erwähnten Abschnitt 14 der Aussenseite der Gebäudewand 5 gebildet, welcher sich im wesentlichen oberhalb der Wandöffnung 8 befindet.Such a housing 3 is assigned via the free and vertically extending edges 9 of the side walls 71 and 72 of the same of the outer surface 14 of the building wall 5 in a manner known per se. Under certain circumstances, even only the pressure of the earth 4 on the outside of the vertically extending transverse wall 6 of the housing 3 is sufficient to keep this housing 3 in a desired position relative to the building opening 8. The walls 6, 71 and 72 of the housing 3 define three walls of the shaft 2. The fourth wall of the shaft 2 is formed by the mentioned portion 14 of the outside of the building wall 5, which is located substantially above the wall opening 8.

Im Gehäuse 3 befindet sich ein lichtführender Kanal 10. Das eine Ende dieses Lichtkanals 10 befindet sich im Bereich des Niveaus des Erdreiches 4, sodass Licht durch dieses Ende in den Kanal 10 gelangen kann. Das andere Ende des Lichtkanals 10 ist der Gebäudeöffnung 8 zugeordnet. Folglich erstreckt sich der Lichtkanal 10 zwischen dem oberen Niveau des Erdreiches 4 und der unterirdisch liegenden Wandöffnung 8. Der Lichtkanal 10 weist einen äusseren Abschnitt 11 und einen inneren Abschnitt 12 auf. Der äussere Abschnitt 11 des Lichtkanals 10 dient vor allem zur Führung des eingefangenen Lichts über den Höhenunterschied zwischen dem Erdniveau 4 und dem Bereich der Wandöffnung 8. Der innere Abschnitt 12 des Lichtkanals 10 dient vor allem zur Umlenkung des zugeführten Lichts in die Wandöffnung 8 und dadurch auch zur Zuführung von Licht in das Innere des zu beleuchtenden Raumes 42.In the housing 3 is a light-guiding channel 10. The one end of this light channel 10 is located in the region of the level of the soil 4, so that light can pass through this end in the channel 10. The other end of the light channel 10 is associated with the building opening 8. Consequently, the light channel 10 extends between the upper level of the soil 4 and the subterranean wall opening 8. The light channel 10 has an outer portion 11 and an inner portion 12. The outer portion 11 of the light channel 10 is mainly used to guide the captured light on the difference in height between the earth level 4 and the area of the wall opening 8. The inner portion 12 of the light channel 10 is used mainly for deflecting the supplied Light in the wall opening 8 and thereby also for supplying light into the interior of the space to be illuminated 42nd

Der Querschnitt des äusseren Abschnittes 11 des Lichtkanals 10 ist im dargestellten Fall rechteckförmig. Dieser äussere Kanalabschnitt 11 weist zumindest zwei einander gegenüberliegende Reflektorelemente 91 und 92 auf, welche flächenhaft sind und welche parallel zur Gebäudewand 5 sowie zur Querwand 6 des Gehäuses 3 verlaufen. Diese Reflektorelemente 91 und 92 können als Reflektorplatten 91, 92 ausgeführt sein, welche parallel zueinander verlaufen. Eine dieser Reflektorplatten 91 ist der Aussenfläche 14 der Gebäudewand 5 oberhalb der Gebäudeöffnung 8 zugeordnet und hier ist sie in einer an sich bekannten Weise befestigt. Die gegenüberliegende bzw. zweite Reflektorplatte 92 ist der Innenseite der Querwand 6 des Gehäuses 3 zugeordnet und hier ist sie in einer an sich bekannten Weise befestigt.The cross section of the outer portion 11 of the light channel 10 is rectangular in the illustrated case. This outer channel section 11 has at least two mutually opposite reflector elements 91 and 92, which are planar and which run parallel to the building wall 5 and to the transverse wall 6 of the housing 3. These reflector elements 91 and 92 may be embodied as reflector plates 91, 92, which run parallel to one another. One of these reflector plates 91 is associated with the outer surface 14 of the building wall 5 above the building opening 8 and here it is fixed in a manner known per se. The opposite or second reflector plate 92 is associated with the inside of the transverse wall 6 of the housing 3 and here it is fixed in a manner known per se.

Um eine höhere Ausbeute bei der Führung von Licht vom Anfang des Lichtkanals 10 zur Gebäudeöffnung 8 zu erreichen, sind zwei weitere, seitliche Reflektorelemente 93 und 94 (Fig. 4) im Lichtkanal 10 angeordnet. Auch diese Reflektorelemente 93 und 94 können als Reflektorplatten ausgeführt sein, die parallel zueinander verlaufen. Die Platten 93 und 94 dieses Reflektorpaares stehen zu den Platten 91 und 92 des ersten Reflektorpaares senkrecht, wobei die Ränder je einer dieser weiteren Platten 93 bzw. 94 mit den Rändern der Platten 91 und 92 des ersten Reflektorpaares verbunden sind. Je eine dieser weiteren Reflektorplatten 93 und 94 liegt näher zur Innenseite einer der Seitenwände 71 bzw. 72 des Gehäuses 3. Die zwei weiteren bzw. seitlichen Reflektorelemente 93 und 94 weisen zumindest einen Abschnitt auf, welcher im oberen Abschnitt 11 des Lichtkanals 10 angeordnet ist. Folglich umfasst ein solcher oberer Abschnitt 11 des Lichtkanals 10 gesamthaft vier reflektierende Elemente 91 bis 94, welche den Mantel eines Quaders darstellen.In order to achieve a higher yield in the guidance of light from the beginning of the light channel 10 to the building opening 8, two further, lateral reflector elements 93 and 94 (FIG. Fig. 4 ) are arranged in the light channel 10. These reflector elements 93 and 94 can also be designed as reflector plates which run parallel to one another. The plates 93 and 94 of this reflector pair are perpendicular to the plates 91 and 92 of the first pair of reflectors, wherein the edges of each of these further plates 93 and 94 are connected to the edges of the plates 91 and 92 of the first pair of reflectors. Depending on one of these further reflector plates 93 and 94 is closer to the inside of one of the side walls 71 and 72 of the housing 3. The two further or lateral reflector elements 93 and 94 have at least a portion which is arranged in the upper portion 11 of the light channel 10. Consequently, such an upper portion 11 of the light channel 10 comprises, as a whole, four reflecting elements 91 to 94, which constitute the envelope of a cuboid.

Die reflektierenden Platten 91 und 92, welche parallel zur Querwand 6 des Gehäuses 3 angeordnet sind, befinden sich im oberen Abschnitt des Schachtes 2 bzw. des Gehäuses 3 und sie reichen von hier ungefähr bis zur Mitte des Schachtes 2 hinab, höchstens jedoch bis zur oberen Kante 18 der Aussparung 8 in der Gebäudewand 5. Die reflektierenden Platten 93 und 94, welche senkrecht zur Querwand 6 des Gehäuses 3 angeordnet sind, beginnen im oberen Abschnitt des Schachtes 2 bzw. des Gehäuses 3 und sie reichen von hier ungefähr bis in den unteren Bereich des Schachtes 2 bzw. des Gehäuses 3 hinab, sodass sie sich praktisch über die ganze Höhe des Gehäuses 3 erstrecken.The reflective plates 91 and 92, which are arranged parallel to the transverse wall 6 of the housing 3, are located in the upper portion of the shaft 2 and the housing 3 and they extend from here approximately to the middle of the shaft 2 down, but at most up to the top Edge 18 of the recess 8 in the building wall 5. The reflective plates 93 and 94, which are arranged perpendicular to the transverse wall 6 of the housing 3, begin in the upper portion of the shaft 2 and the housing 3 and they extend from here approximately to the lower Area of the shaft 2 and the housing 3 down, so that they extend practically over the entire height of the housing 3.

Das jeweilige Reflektorelement 91 bis 94 kann einen nicht spiegelnden plattenförmigen Grundkörper haben. Die dem Inneren des Kanals 10 zugewandte Fläche des Grundkörpers solcher Elemente 91 bis 94 ist verspiegelt, um das in das obere Kanalende 38 von oben her eingefallene Licht zu spiegeln und dadurch durch den Lichtkanal 10 weiterzuleiten. Das jeweilige Reflektorelement 91 bis 94 kann jedoch auch als ein Spiegel ausgeführt sein.The respective reflector element 91 to 94 may have a non-reflecting plate-shaped base body. The interior of the channel 10 facing surface of the body of such elements 91 to 94 is mirrored to reflect the sunken into the upper channel end 38 from above light and thereby pass through the light channel 10. However, the respective reflector element 91 to 94 may also be designed as a mirror.

Der obere und an sich offene Endbereich 38 des Gehäuses 3 ist mit Hilfe einer Abdeckvorrichtung 15 überdacht. Diese Vorrichtung 15 ist als Deckel 41 ausgeführt. Dieser Deckel 41 ist als eine Platte aus einem lichtdurchlässigen oder sogar durchsichtigen Material hergestellt. Bei einem solchen Material kann es sich um eines der an sich bekannten Materialien dieser Art handeln. Vorzugsweise kann es sich um Glas oder Plexiglas handeln. Bei Glas kann aus Gründen der Stabilität vorzugsweise Panzerglas verwendet werden. Die eine Randpartie 16 des Deckels 41 schliesst sich an die Aussenseite 14 der Gebäudewand 5 an. Die gegenüberliegende Randpartie 17 des Deckels 41 befindet sich im Bereich der Querwand 6 des Gehäuses 3.The upper and per se open end portion 38 of the housing 3 is covered by means of a covering device 15. This device 15 is designed as a lid 41. This lid 41 is made as a plate of a translucent or even transparent material. Such a material may be one of the known materials of this type. Preferably, it may be glass or Plexiglas. For glass, armored glass can preferably be used for reasons of stability. The one edge part 16 of the lid 41 adjoins the outside 14 of the building wall 5. The opposite edge portion 17 of the lid 41 is located in the region of the transverse wall 6 of the housing third

Die Höhe bzw. die in der vertikalen Richtung verlaufende Länge der ersten parallelen Reflektorplatte 91, welche an der Gebäudewand 5 näher liegt, ist so eingestellt, dass die untere Kante 911 dieser Platte 91 auf dem Niveau der oberen Kante 18 der Gebäudeöffnung 8 liegt. Die obere Kante 912 dieser Reflektorplatte 91 liegt oberhalb der oberen Kanten 37 der Seitenwände 71 und 72 des Gehäuses 3. Die obere Kante 922 der gegenüberliegenden parallelen Reflektorplatte 92 liegt zwar ebenfalls oberhalb der oberen Kanten 37 der Seitenwände 71 und 72 des Gehäuses 3, diese obere Plattenkante 922 liegt jedoch unterhalb der genannten oberen Kante 912 der ersten parallelen Reflektorplatte 91.The height or the length in the vertical direction of the first parallel reflector plate 91, which is closer to the building wall 5, is set so that the lower edge 911 of this plate 91 at the level of the upper Edge 18 of the building opening 8 is located. The upper edge 912 of this reflector plate 91 lies above the upper edges 37 of the side walls 71 and 72 of the housing 3. Although the upper edge 922 of the opposite parallel reflector plate 92 is also above the upper edges 37 of the side walls 71 and 72 of the housing 3, this upper However, plate edge 922 lies beneath said upper edge 912 of the first parallel reflector plate 91.

Der Deckel 41 liegt auf den oberen Kanten 912 und 922 der parallelen Reflektorplatten 91 und 92 auf. Die der Gebäudewand 5 zugeordnete Randpartie 16 des Deckels 41 liegt auf der oberen Kante 912 der der Gebäudewand 5 zugeordneten Reflektorplatte 91 auf. Die von der Gebäudewand 5 entfernt liegende Randpartie 17 des Deckels 41 liegt auf der oberen Kante 922 der von der Gebäudewand 5 entfernt liegenden Reflektorplatte 92 auf. Daraus ergibt sich eine geneigte Lage des Deckels 41, welche in Fig. 1 dargestellt ist.The lid 41 rests on the upper edges 912 and 922 of the parallel reflector plates 91 and 92. The building wall 5 associated edge portion 16 of the lid 41 rests on the upper edge 912 of the building wall 5 associated reflector plate 91. The edge part 17 of the cover 41 remote from the building wall 5 rests on the upper edge 922 of the reflector plate 92 remote from the building wall 5. This results in an inclined position of the lid 41, which in Fig. 1 is shown.

Die senkrechten bzw. seitlichen Reflektoren 93 und 94 des Lichtführkanals 10 können über die oberen Kanten 37 der Seitenwände 71 und 72 des Gehäuses 3 hinausragen. Der jeweilige empor verlängerte Abschnitt 931 der Seitenreflektoren 93 und 94 ist mit einer schräg verlaufenden, oberen Kante abgeschlossen. Die Neigung dieser Kante entspricht der Neigung der Deckplatte 41, sodass die Deckplatte 41 auch auf diesen Schrägkanten der Seitenreflektoren 93 und 94 aufliegt.The vertical or lateral reflectors 93 and 94 of the light guide channel 10 may protrude beyond the upper edges 37 of the side walls 71 and 72 of the housing 3. The respective upwardly extended portion 931 of the side reflectors 93 and 94 is terminated with a sloping upper edge. The inclination of this edge corresponds to the inclination of the cover plate 41, so that the cover plate 41 rests on these beveled edges of the side reflectors 93 and 94.

Die zweite bzw. vom Gebäude 5 entfernt liegende Randpartie 17 des Deckels 41 endet bei der Einrichtung gemäss Fig. 1 im Bereich der äusseren Reflektorplatte 92, d.h. noch vor der Querwand 6 und somit oberhalb des Hohlraumes des Gehäuses 3. Die äussere Kante 17 des Deckels 41 liegt erst hinter dieser äusseren Reflektorplatte 92. Zwischen dieser Reflektorplatte 92 und der Querwand 6 des Gehäuses 3 gibt es einen Spalt 19. Um zu verhindern, dass Regenwasser in diesen Spalt 19 und somit auch ins Innere des Gehäuses 3 gelangt, ist der von der Wand 5 entfernt liegende Rand des Deckels 41 mit einem Vordach 411 versehen. Dieses Vordach 411 stellt im Prinzip eine Verlängerung des Deckels 41 bis hinter die Querwand 6 des Gehäuses 3 dar. Dieses Vordach 411 kann beispielsweise als ein Blechstreifen ausgeführt sein, welcher sich entlang der Randpartie 17 des Deckels 41 erstreckt und dessen längeren Kanten praktisch parallel zur Oberkante 922 der zweiten Reflektorplatte 92 verlaufen. Dieser Materialstreifen 411 ist in seiner Längsrichtung gebogen, sodass er zwei Schenkel 4111 und 4112 aufweist. Die freie Randpartie des erstgenannten Schenkels 4111 ist dem Rand 17 des Deckels 41 zugeordnet und hier befestigt. Dieser Schenkel 4111 ist so breit, dass sich der zweite und abwärts gerichtete Streifenschenkel 4112 erst hinter der Aussenseite der Querwand 6 des Gehäuses befindet. Dieser zweite Streifenschenkel 4112 ist so breit bzw. hoch ausgeführt, dass seine freie untere Kante unterhalb der oberen Kante der Querwand 6 liegt.The second or away from the building 5 edge portion 17 of the lid 41 ends in the device according to Fig. 1 in the region of the outer reflector plate 92, ie even before the transverse wall 6 and thus above the cavity of the housing 3. The outer edge 17 of the lid 41 is located only behind this outer reflector plate 92. Between this reflector plate 92 and the transverse wall 6 of the housing 3 there a gap 19. To prevent rainwater in this gap 19 and thus also into the interior of the housing. 3 reaches, the edge of the cover 41 remote from the wall 5 is provided with a canopy 411. This canopy 411 is in principle an extension of the lid 41 to behind the transverse wall 6 of the housing 3. This canopy 411 may be embodied for example as a sheet metal strip which extends along the edge portion 17 of the lid 41 and its longer edges practically parallel to the upper edge 922 of the second reflector plate 92 extend. This strip of material 411 is bent in its longitudinal direction so that it has two legs 4111 and 4112. The free edge portion of the first leg 4111 is associated with the edge 17 of the lid 41 and fastened here. This leg 4111 is so wide that the second and downward strip leg 4112 is located only behind the outside of the transverse wall 6 of the housing. This second strip leg 4112 is made so wide or high that its free lower edge is below the upper edge of the transverse wall 6.

Der innere Abschnitt 12 des Lichtkanals 10 schliesst sich an das untere Ende des äusseren Abschnittes 11 des Lichtkanals 10 an, und zwar derart, dass das Licht, welches durch den äusseren Abschnitt 11 des Lichtkanals 10 bis zum oberen Ende des inneren Abschnittes 12 des Lichtkanals 10 gelangt, durch diesen inneren Abschnitt 12 des Lichtkanals 10 in die Wandöffnung 8 reflektiert wird. Der innere Abschnitt 12 des Lichtkanals 10 umfasst ein Reflektorelement 20, welches als eine gebogene und Licht reflektierende Platte ausgeführt ist. Dieses Reflektorelement 20 steht der Wandöffnung 8 gegenüber. Dieses Reflektorelement 20 stellt einen Abschnitt des Mantels eines Zylinders dar, dessen Längsachse horizontal verläuft. Der Zylinder weist einen Radius R auf, welcher von einem Mittelpunkt M ausgeht, durch welchen auch die Längsachse des Zylinders hindurchgeht. Dieser Mittelpunkt M liegt im Inneren der Wandöffnung 8 und ausserdem in einer Ebene B, welche horizontal verläuft. Der Zylinderabschnitt 20 weist geradlinig verlaufende Kanten 201 und 202 auf, welche ebenfalls horizontal und zugleich parallel zur Längsachse des Zylinders verlaufen.The inner portion 12 of the light channel 10 adjoins the lower end of the outer portion 11 of the light channel 10 in such a way that the light passing through the outer portion 11 of the light channel 10 to the upper end of the inner portion 12 of the light channel 10th passes through this inner portion 12 of the light channel 10 is reflected in the wall opening 8. The inner portion 12 of the light channel 10 comprises a reflector element 20, which is designed as a curved and light-reflecting plate. This reflector element 20 faces the wall opening 8. This reflector element 20 represents a portion of the shell of a cylinder whose longitudinal axis is horizontal. The cylinder has a radius R, which starts from a center M, through which passes also the longitudinal axis of the cylinder. This center M is located inside the wall opening 8 and also in a plane B, which extends horizontally. The cylinder portion 20 has rectilinear edges 201 and 202 which are also horizontal and at the same time parallel to the longitudinal axis of the cylinder.

Der Radius R ist so gewählt, dass die erste bzw. obere Kante 201 dieses konkaven Reflektors 20 der unteren Kante 921 des zweiten planen Reflektors 92 im äusseren Abschnitt 11 des Lichtkanals 10 stumpf zugeordnet ist. Diese Kanten 201 und 921 liegen ebenfalls in der genannten Horizontalebene B. Die zweite Kante 202 des konkaven Reflektors 20 ist beim genannten Radius R der unteren Kante 181 der Oeffnung 8 in der Wand 5 zugeordnet. Dabei kann diese untere Reflektorkante 202 an der Aussenseite 14 der Gebäudewand 5 anliegen oder sich in einem Abstand von dieser Aussenseite bzw. Aussenfläche 14 befinden. Die konkav gewölbte Innenseite des Hohlreflektors 20 ist gleichfalls verspiegelt. Dies ermöglicht, dass das durch den äusseren Abschnitt 11 des Lichtkanals 10 vertikal anfallende Licht in die Wandöffnung 8 reflektiert wird.The radius R is selected such that the first or upper edge 201 of this concave reflector 20 is associated with the lower edge 921 of the second planar reflector 92 in the outer portion 11 of the light channel 10 blunt. These edges 201 and 921 are also located in said horizontal plane B. The second edge 202 of the concave reflector 20 is associated with said radius R of the lower edge 181 of the opening 8 in the wall 5. In this case, this lower reflector edge 202 may rest on the outer side 14 of the building wall 5 or be located at a distance from this outer side or outer surface 14. The concave inside of the hollow reflector 20 is also mirrored. This allows the light incident vertically through the outer portion 11 of the light channel 10 to be reflected into the wall opening 8.

Zur Erhöhung der Lichtausbeute bei der Reflexion des Lichts in die Wandöffnung 8 sind die Seitenreflektoren 93 und 94 des äusseren Abschnittes 11 des Lichtkanals 10 bis in den Bereich des inneren Abschnittes 12 des Lichtkanals 10 verlängert, sodass sie bis zur unteren Kante 181 der Wandöffnung 8 reichen. Dabei kann jene untere Eckpartie des jeweiligen Seitenreflektors 93 und 94, welche zur Querwand 6 des Gehäuses 3 näher liegt, entsprechend dem Verlauf des hohlen Reflektors 20 abgerundet sein.To increase the luminous efficacy in the reflection of the light in the wall opening 8, the side reflectors 93 and 94 of the outer portion 11 of the light channel 10 are extended into the region of the inner portion 12 of the light channel 10 so that they reach the lower edge 181 of the wall opening 8 , In this case, those lower corner part of the respective side reflector 93 and 94, which is closer to the transverse wall 6 of the housing 3, corresponding to the course of the hollow reflector 20 may be rounded.

Die Wandöffnung 8 kann zumindest teilweise durch ein Fenster 1 verschlossen bzw. verschliessbar sein. Das Fenster 1 befindet sich im dargestellten Fall vor der Aussparung 8, d.h. an der Aussenseite 14 der Seitenwand 5 des Gebäudes. Im in Fig. 1 dargestellten Fall umfasst dieses Fenster 1 nur eine durchsichtige Platte 21, beispielsweise aus Glas, welche praktisch in gleicher Ebene liegt wie der erste parallele Reflektor 91 des äusseren Abschnittes 11 des Lichtkanals 10. Die Glasplatte 21 kann zur Halterung an der Wandöffnung 8 in einer geeigneten Weise eingefasst sein, beispielsweise in einem Rahmen 22. Dieser Rahmen 22 verleiht der Glasscheibe 21 Stabilität und trägt zugleich einen Teil des Gewichtes der Reflektorplatte 91. Die untere Kante 911 des zuletzt genannten Reflektors 91 liegt im dargestellten Fall auf der Oberseite des oberen, horizontalen Schenkels 221 des Fensterrahmens 22 auf. Die Unterseite des untere horizontalen Schenkels 222 des Rahmens 22 liegt auf der Innenseite der unteren Kante 202 des hohlen Reflektors 20 auf. Die Abmessungen des Rahmens 22 bzw. der Fensterplatte 21 allein sind bei dieser Einrichtung so gewählt, dass das Fenster 1 die gesamte Fläche der Wandöffnung 8 überdeckt.The wall opening 8 can be at least partially closed or closable by a window 1. The window 1 is located in the illustrated case in front of the recess 8, ie on the outside 14 of the side wall 5 of the building. Im in Fig. 1 In the case shown, this window 1 comprises only a transparent plate 21, for example of glass, which lies practically in the same plane as the first parallel reflector 91 of the outer portion 11 of the light channel 10. The glass plate 21 can be mounted on the wall opening 8 in a suitable manner This frame 22 gives the glass sheet 21 stability and at the same time carries a part of the weight of the reflector plate 91. The lower edge 911 of the latter reflector 91st in the case shown on the top of the upper horizontal leg 221 of the window frame 22. The underside of the lower horizontal leg 222 of the frame 22 rests on the inside of the lower edge 202 of the hollow reflector 20. The dimensions of the frame 22 and the window plate 21 alone are selected in this device so that the window 1 covers the entire surface of the wall opening 8.

Falls alle Stellen der vorliegenden Einrichtung, wo sich die einzelnen Platten des Lichtleitkanals 10 treffen, möglichst feuchtigkeitsdicht ausgeführt sind, was mit Hilfe von an sich bekannten Mitteln erreichbar ist, so kann das Beschlagen der reflektierenden Flächen der Platten mit Feuchtigkeit weitgehend vermieden werden.If all points of the present device where meet the individual plates of Lichtleitkanals 10, as moisture-tight as possible, which is accessible by means known per se, the fogging of the reflective surfaces of the plates can be largely avoided with moisture.

Die soeben beschriebene Ausführungsform der vorliegenden Einrichtung setzt voraus, dass es genügt, wenn allein Licht in den Innenraum 42 eingeführt wird. Denn die Glasscheibe 21 des Fensters 1 verdeckt die gesamte Fläche der Wandöffnung 8. Es gibt jedoch auch Fälle, in welchen man nicht nur Licht in den Raum 42 zuführen will sondern in welchen man den Raum 42 auch belüften möchte. Eine solche Ausführung der vorliegenden Einrichtung ist in Fig. 2 bis 4 dargestellt.The just described embodiment of the present device assumes that it is sufficient if only light is introduced into the interior space 42. For the glass pane 21 of the window 1 covers the entire surface of the wall opening 8. However, there are also cases in which you want to perform not only light in the room 42 but in which one wants to ventilate the room 42 also. Such an embodiment of the present device is in Fig. 2 to 4 shown.

Die in Fig. 2 in einer Seitenansicht dargestellte Ausführung der vorliegenden Einrichtung weist einen Aufsatz 25 auf, welcher auf die obere Stirnpartie 38 des Gehäuses 3 aufgesetzt bzw. aufsetzbar ist. Dieser Aufsatz 25 weist einen im wesentlichen keilförmigen Grundkörper 26 auf, welcher aus einem Material sein kann, welches weder durchsichtig noch durchscheinend zu sein braucht. Dieser Grundkörper 26 kann beispielsweise aus Blech sein.In the Fig. 2 In a side view illustrated embodiment of the present device has an attachment 25 which is placed or placed on the upper end portion 38 of the housing 3. This attachment 25 has a substantially wedge-shaped base body 26, which may be made of a material which needs to be neither transparent nor translucent. This base body 26 may be made of sheet metal, for example.

Der Aufsatzgrundkörper 26 umfasst eine Deckwand 27, welche schräg verläuft, und zwar etwa so wie die vorstehend beschriebene Deckplatte 41. Im Bereich der Querwand 6 des Gehäuses 3 hängt von der Deckwand 27 eine Stirnwand 29 des Aufsatzes 25 herab. Von der jeweiligen Seitenkante der Deckwand 27 hängen je eine Seitenwand 28 des Aufsatzes 25 herab, von welchen in Fig. 2 nur die vordere Seitenwand 28 ersichtlich ist. Die jeweilige Seitenwand 28 des Aufsatzes 25 ist im wesentlichen keilförmig. Dabei weist die Seitenwand 28 eine untere Kante 281 auf, welche praktisch horizontal verläuft und welche der Aussenseite des Gehäuses 3 zugeordnet ist bzw. sein kann. Von den Enden dieser Horizontalkante 281 der Aufsatzseitenwand 28 ragen zwei Stirnkanten 282 und 283 dieser Aufsatzseitenwand 28 empor.The attachment base body 26 comprises a cover wall 27, which extends obliquely, approximately like the cover plate 41 described above. In the region of Transverse wall 6 of the housing 3 depends on the top wall 27 an end wall 29 of the attachment 25 down. Depending on the respective side edge of the top wall 27 depending hang a side wall 28 of the top 25, of which in Fig. 2 only the front side wall 28 can be seen. The respective side wall 28 of the attachment 25 is substantially wedge-shaped. In this case, the side wall 28 has a lower edge 281, which extends virtually horizontally and which is assigned to the outside of the housing 3 or can be. From the ends of this horizontal edge 281 of the attachment side wall 28 protrude two end edges 282 and 283 of this attachment side wall 28 upwards.

Die erste dieser Vertikalkanten 282 ist der Gebäudewand 5 zugeordnet. Die der Gebäudewand 5 zugeordnete Randpartie 16 der Deckwand 27 kann an der Wand 5 angeschlagen sein, sodass der Aufsatz 25 hier keine herabhängende Wand aufweisen muss. Die zweite der Vertikalkanten 283 der Aufsatzseitenwand 28 befindet sich im Bereich der Querwand 6 des Gehäuses 3 und diese Kante 283 ist kürzer als die erste Vertikalkante 282. Zwischen den kürzeren Vertikalkanten 283 der Aufsatzseitenwände 28 erstreckt sich die bereits genannte Stirnwand 29 des Aufsatzes 25. Die horizontal gerichtete Länge der Seitenwände 28 ist grösser als die Tiefe des Gehäuses 3 bzw. als die Breite seiner Seitenwände 71 und 72, sodass der Aufsatz 25 die Querwand 6 des Gehäuses 3 übergreift und dadurch das Innere des Gehäuses 3 vor dem Eindringen von Regenwasser schützt.The first of these vertical edges 282 is associated with the building wall 5. The building wall 5 associated edge portion 16 of the top wall 27 may be posted on the wall 5, so that the article 25 here does not have to have a hanging wall. The second of the vertical edges 283 of the attachment side wall 28 is located in the region of the transverse wall 6 of the housing 3 and this edge 283 is shorter than the first vertical edge 282. Between the shorter vertical edges 283 of the attachment side walls 28 extends the already mentioned end wall 29 of the attachment 25. Die horizontally directed length of the side walls 28 is greater than the depth of the housing 3 and as the width of its side walls 71 and 72, so that the article 25, the transverse wall 6 of the housing 3 overlaps and thereby protects the interior of the housing 3 from the ingress of rainwater.

Im Inneren des Schachtes 2 befindet sich ein Lichtleitkanal 30. Dieser Kanal 30 weist ebenfalls einen äusseren Abschnitt 31 und einen inneren Abschnitt 32 auf. Das äussere Ende des äusseren Abschnittes 31 des Lichtleitkanals 30 geht durch die Deckwand 27 des Aufsatzes 25 hindurch und dieses Ende bzw. diese Lichteintrittsöffnung 70 des Kanals 30 ist mit Hilfe einer zumindest durchscheinenden Platte 33 abgeschlossen bzw. zugedeckt. Durch diese Platte 33 gelangt Licht in den Lichtführkanal 30.Inside the shaft 2 is a Lichtleitkanal 30. This channel 30 also has an outer portion 31 and an inner portion 32. The outer end of the outer portion 31 of the Lichtleitkanals 30 passes through the top wall 27 of the cap 25 and this end or this light inlet opening 70 of the channel 30 is closed or covered by means of an at least translucent plate 33. Through this plate 33, light enters the light guide channel 30th

Der äussere Abschnitt 31 des vorliegenden Lichtleitkanals 30 kann im wesentlichen gleich ausgeführt sein wie der äussere Abschnitt 11 des Lichtleitkanals 10 gemäss Fig. 1, sodass der vorliegende Kanal 30 ebenfalls die Reflektoren 91, 92 usw. aufweisen kann. Da die Wandöffnung 8 verhältnismässig nahe an der oberen Stirnfläche 38 des Gehäuses 3 liegt, können die parallelen Reflektorelemente 91 und 92 beim in Fig. 2 dargestellten äusseren Abschnitt 31 des Kanals 30 gegenüber der Vertikalen schräg verlaufen. Zugleich können diese Reflektoren 91 und 92 senkrecht zur lichtdurchlässigen Abdeckplatte 33 stehen. Im dargestellten Fall laufen die Längskanten 95 und 96 dieser Reflektoren 91 und 92 gegen die Wandöffnung 8 hin etwas zusammen, sodass der Winkel, welcher sich zwischen der jeweiligen Längskante 95 bzw. 96 des jeweiligen Reflektors 91 bzw. 92 und der Abdeckplatte 33 erstreckt, von 90 Grad unterschiedlich ist.The outer portion 31 of the present Lichtleitkanals 30 may be performed substantially the same as the outer portion 11 of the Lichtleitkanals 10 according Fig. 1 so that the present channel 30 may also have the reflectors 91, 92, etc. Since the wall opening 8 is relatively close to the upper end face 38 of the housing 3, the parallel reflector elements 91 and 92 when in Fig. 2 shown outer portion 31 of the channel 30 with respect to the vertical oblique. At the same time, these reflectors 91 and 92 may be perpendicular to the translucent cover 33. In the case illustrated, the longitudinal edges 95 and 96 of these reflectors 91 and 92 converge slightly towards the wall opening 8, so that the angle which extends between the respective longitudinal edge 95 or 96 of the respective reflector 91 or 92 and the cover plate 33 90 degrees is different.

Eine gegenüber der Vertikalen schräg verlaufende Vertiefung 34 ist oberhalb der oberen Kante 18 der Wandöffnung 8 in der Gebäudewand 5 ausgeführt. Die Breite dieser Vertiefung 34 entspricht der Breite des äusseren Abschnittes 31 des Lichtleitkanals 30, welche durch die querstehenden Reflektoren 93 und 94 (Fig. 4) dieses Kanalabschnittes 31 gegeben ist. Folglich kann ein etwa mittlerer Teil des äusseren Abschnittes 31 des Lichtleitkanals 30, welcher den ersten wandparallelen Reflektor 91 umfasst, durch die genannte schräge Vertiefung 34 hindurchgehen. Die untere Kante 911 des ersten wandparallelen Reflektors 91 liegt dabei im Inneren der Wandöffnung 8. Durch diese Massnahme kann man ausserdem einen geringen Abstand zwischen der durch die Abdeckplatte 33 abgedeckten Lichteinfallöffnung im Aufsatz 25 und der Gebäudewand 5 erreichen.A relative to the vertical oblique recess 34 is executed above the upper edge 18 of the wall opening 8 in the building wall 5. The width of this recess 34 corresponds to the width of the outer portion 31 of the Lichtleitkanals 30, which by the transverse reflectors 93 and 94 (FIG. Fig. 4 ) of this channel section 31 is given. Consequently, an approximately central part of the outer portion 31 of the light guide channel 30, which comprises the first wall-parallel reflector 91, can pass through said oblique recess 34. The lower edge 911 of the first wall-parallel reflector 91 lies in the interior of the wall opening 8. By this measure, one can also achieve a small distance between the covered by the cover 33 light incidence opening in the top 25 and the building wall 5.

Wegen dem geringen Abstand zwischen der Lichteinfallöffnung im Aufsatz 25 und der Wandöffnung 8 kann der zweite wandparallele Reflektor 92 des äusseren Kanalabschnittes 31 tief in den Schacht 2 eindringen, sodass ein wesentlicher Teil desselben der Wandöffnung 8 gegenübersteht. Da dieser zweite Reflektor 92 gegenüber der Vertikalen schräg steht, reflektiert der der Wandöffnung 8 gegenüberstehende Abschnitt dieses zweiten Reflektors 92 genug Licht direkt in den Innenraum 42.Because of the small distance between the light incidence opening in the cap 25 and the wall opening 8, the second wall-parallel reflector 92 of the outer channel section 31 can penetrate deeply into the shaft 2, so that a substantial part thereof faces the wall opening 8. Since this second reflector 92 is inclined with respect to the vertical, that of the wall opening 8 reflects opposite section of this second reflector 92 enough light directly into the interior 42nd

Der innere Abschnitt 32 des Lichtleitkanals 30 schliesst sich einerseits an das innenliegende Ende des äusseren Kanalabschnittes 31 und andererseits an die Wandöffnung 8 an. Im Bereich der unteren Kante 911 des ersten wandparallelen Reflektors 91 bedarf der Innenabschnitt 32 keines gesonderten Reflektors, weil diese untere Kante 911 in der Wandöffnung 8 bereits liegt.The inner portion 32 of the Lichtleitkanals 30 closes on the one hand to the inner end of the outer channel portion 31 and on the other hand to the wall opening 8 at. In the region of the lower edge 911 of the first wall-parallel reflector 91, the inner section 32 does not require a separate reflector, because this lower edge 911 is already located in the wall opening 8.

Der innere Abschnitt 32 des Lichtleitkanals 30 weist einen unten liegenden Reflektor 35 auf, welcher als eine plane reflektierende Platte ausgeführt ist. Eine der Kanten dieser Reflektorplatte 35 ist der unteren Kante 921 des zweiten Reflektors 92 im oberen Kanalabschnitt 31 stumpf zugeordnet. Die gegenüberliegende Kante 351 dieses unteren Reflektors 35 liegt in der Wandöffnung 8. Zur Unterstützung der Reflexion von Licht ist dieser untere Reflektor 35 ähnlich wie der zweite Reflektor 92 jedoch etwas mehr gegenüber der Vertikalen geneigt. Die zur Wand 5 quer stehenden Reflektoren 93 und 94 (Fig. 4) weisen in ihrem unteren Bereich Ausläufer auf, deren untere Kanten den Seitenkanten des unteren Reflektors 35 zugeordnet sind, wodurch der Lichtkanal 30 von der Einfallöffnung 70 bis zur Austrittsmündung 45 desselben seitlich als geschlossen gilt.The inner portion 32 of the Lichtleitkanals 30 has a bottom reflector 35, which is designed as a flat reflective plate. One of the edges of this reflector plate 35 is associated with the lower edge 921 of the second reflector 92 in the upper channel section 31 butt. The opposite edge 351 of this lower reflector 35 is located in the wall opening 8. However, to assist in the reflection of light, this lower reflector 35, like the second reflector 92, is slightly more inclined with respect to the vertical. The reflectors 93 and 94 (FIG. Fig. 4 ) have in their lower part foothills, whose lower edges are associated with the side edges of the lower reflector 35, whereby the light channel 30 from the inlet opening 70 to the outlet mouth 45 thereof laterally considered closed.

Zumindest in einer der Seitenwände 28 des Gehäuseaufsatzes 25 ist eine Oeffnung 36 ausgeführt, durch welche Luft zwischen dem Inneren des Gehäuses 3 und der Umgebung desselben strömen kann. Zweckmässigerweise ist diese Oeffnung 36 mit Hilfe eines an sich bekanntes Gitters 361 überdeckt.At least in one of the side walls 28 of the housing attachment 25, an opening 36 is formed, through which air can flow between the interior of the housing 3 and the surroundings thereof. Conveniently, this opening 36 is covered by means of a known lattice 361.

Fig. 3 zeigt in einer Frontansicht ein Fenster 1, welches im Zusammenhang mit jenen Ausführungen der vorliegenden Einrichtung verwendbar ist, die nicht nur die Zuführung von Licht sondern auch die Zuführung von Luft in den Innenraum 42 ermöglichen sollen. In Fig. 3 ist dieses Fenster 1 in einer ersten Frontansicht gezeigt, und zwar vom zu beleuchtenden Innenraum 42 her gesehen. Fig. 3 shows in a front view a window 1, which is useful in connection with those embodiments of the present device, which not only the supply of light but also the supply of air into the interior 42nd should allow. In Fig. 3 This window 1 is shown in a first front view, seen from the interior 42 to be illuminated.

Dieses Fenster 1 ist in der Wandöffnung 8 einsetzbar und in einer an sich bekannten Weise befestigbar und es ist in zwei Bereiche unterteilt. Im ersten dieser Bereiche befindet sich die bereits besprochene Glasscheibe 21, welche die gesamte Fläche dieses Bereiches einnimmt bzw. überdeckt und die den Einlass von Licht in den Innenraum 42 ermöglicht. Der zweite Bereich des Fensters 1 ist für den Durchlass von Luft ausgebildet. Im dargestellten Fall ist die Fläche dieses zweiten Fensterbereiches durch eine Platte 39 ausgefüllt bzw. überdeckt, welche weder durchsichtig noch durchscheinend zu sein braucht. Zweckmässigerweise ist diese Platte 39 aus einem Metall oder aus Holz und in dieser Platte 39 ist eine Oeffnung 43 für den Durchlass von Luft ausgeführt.This window 1 can be used in the wall opening 8 and fastened in a manner known per se and it is divided into two areas. In the first of these areas is the already discussed glass pane 21, which occupies or covers the entire area of this area and which allows the entry of light into the interior space 42. The second area of the window 1 is designed for the passage of air. In the case shown, the surface of this second window area is filled or covered by a plate 39, which need not be transparent or translucent. Conveniently, this plate 39 is made of a metal or wood and in this plate 39 is an opening 43 designed for the passage of air.

Die Breite des Lichtkanals 30, d.h. der Abstand zwischen den zur Wand 5 querstehenden Reflektoren 93 und 94 (Fig. 4), ist bei dieser Ausführung der vorliegenden Einrichtung kleiner als die Breite C des Rahmens 22 des Fensters 1. Die Breite des Lichtkanals 30 entspricht der Breite der Glasplatte 21 im Fensterrahmen 22. Das Austrittsende 45 (Fig. 2) des inneren Abschnittes 32 des Lichtkanals 30 ist dem die Glasscheibe 21 aufweisenden Teil des Fensters 1 von der Aussenseite des Fensters 1 her zugeordnet.The width of the light channel 30, ie the distance between the transverse to the wall 5 reflectors 93 and 94 ( Fig. 4 ), in this embodiment of the present device is smaller than the width C of the frame 22 of the window 1. The width of the light channel 30 corresponds to the width of the glass plate 21 in the window frame 22. The outlet end 45 (FIG. Fig. 2 ) of the inner portion 32 of the light channel 30 is assigned to the glass pane 21 having part of the window 1 from the outside of the window 1 ago.

Die Breite des Gehäuses 3 dieser Einrichtung ist zumindest so gross wie die Breite C des Fensterrahmens 22. Im vorliegenden Fall wird die Breite des Gehäuses 3 als etwas grösser (Fig. 4) wie die Breite C des Fensterrahmens 22 angenommen. Folglich gibt es im Gehäuse 3 einen Nebenraum 24 (Fig. 4), welcher sich neben dem Lichtkanal 30 befindet und sich praktisch parallel zu diesem erstreckt. Die Breite des Nebenraumes 24 entspricht praktisch der Breite D jenes Teiles des Fensterrahmens 22, welcher durch die Luftdurchlassplatte 39 verdeckt ist. Der Nebenraum 24 im Gehäuse 3 ist einerseits durch die Oeffnung 36 (Fig. 2) im Gehäuseaufsatz 25 an die Umgebungsluft und andererseits durch die Oeffnung 43 (Fig. 3) in der Durchlassplatte 39 des Fensters 1 an den Innenraum 42 strömungsmässig angeschlossen. Folglich kann Luft durch den Gehäusenebenraum 24 in den beiden Richtungen strömen.The width of the housing 3 of this device is at least as large as the width C of the window frame 22. In the present case, the width of the housing 3 as a little larger ( Fig. 4 ) is assumed to be the width C of the window frame 22. Consequently, there is a secondary space 24 in the housing 3 (FIG. Fig. 4 ), which is located adjacent to the light channel 30 and extends substantially parallel thereto. The width of the auxiliary space 24 corresponds practically to the width D of that part of the window frame 22 which is covered by the air passage plate 39. The auxiliary space 24 in the housing 3 is on the one hand through the opening 36 ( Fig. 2 ) in the housing attachment 25 to the ambient air and on the other hand through the opening 43 (FIG. Fig. 3 ) in the passage plate 39 of the window 1 to the inner space 42 fluidly connected. Consequently, air can flow through the housing side space 24 in both directions.

Die Deckwand 27 der Einrichtung gemäss Fig. 4 umfasst eine durchsichtige Platte 66, z.B. eine Glasplatte, welche die obere bzw. äussere Mündung 70 des Kanals 30 überdeckt. Diese Deckplatte 66 verläuft praktisch horizontal. Die in Fig. 4 rechts abgebildete Randpartie der Platte 66 liegt auf der oberen Kante 941 der rechts abgebildeten Seitenwand bzw. des rechts abgebildeten Reflektors 94 des Kanals 30 auf, und zwar unter Zwischenlage eines länglichen Abdichtelementes 46, welches sich entlang der genannten Kante 941 erstreckt. Dieses längliche Abdichtelement 46 hat einen im wesentlichen kreuzförmigen Querschnitt, wobei dieses Element 46 zugleich auch eine tragende Funktion ausübt. Einer der horizontalen Schenkel des Kreuzes 46 liegt zwischen dem ersten bzw. rechts abgebildeten Rand 661 der Deckplatte 66 und der oberen Kante 941 des Reflektors 94. Die vertikalen Schenkel des Kreuzes 46 sind an der vertikal verlaufenden Stirnfläche des Randes 661 der Deckplatte 66 und am aussen liegenden, zugeordneten Abschnitt des Randes 941 des Reflektors 94 angeschlagen.The top wall 27 of the device according to Fig. 4 comprises a transparent plate 66, for example a glass plate, which covers the upper or outer mouth 70 of the channel 30. This cover plate 66 extends virtually horizontally. In the Fig. 4 On the right-hand side edge of the plate 66 rests on the upper edge 941 of the right side wall or reflector 94 of the channel 30, with the interposition of an elongated sealing member 46 which extends along said edge 941. This elongated sealing member 46 has a substantially cross-shaped cross section, said element 46 at the same time also carries a supporting function. One of the horizontal legs of the cross 46 is located between the first and the right edge 661 of the cover plate 66 and the upper edge 941 of the reflector 94. The vertical legs of the cross 46 are on the vertical end face of the edge 661 of the cover plate 66 and on the outside lying, associated portion of the edge 941 of the reflector 94 struck.

Der in Fig. 4 links abgebildete vertikale Reflektor 93 des Kanals 30 befindet sich in einem Abstand von der links abgebildeten Seitenwand 72 des Gehäuses 3. Die in Fig. 4 links abgebildete Randpartie 67 der Deckplatte 66 ist so breit ausgeführt, dass sie den Abstand zwischen der Seitenwand 72 und dem Reflektor 93 überbrückt. Im Bereich der innenliegenden oberen Kante der jeweiligen Seitenwand 71 bzw. 72 sowie in der Querwand 6 des Gehäuses 3 ist ein Falz 73 ausgeführt, dessen Längsrichtung mit der Längsrichtung der betreffenden Kante übereinstimmt. Dieser Falz 73 öffnet sich gegen das Innere des Gehäuses 3 sowie gegen aufwärts hin und der Falz 73 weist eine horizontale Flanke 731 und eine vertikale Flanke 732 auf. Auf der horizontalen Flanke 731 des Falzes 73 in der links abgebildeten Seitenwand 72 des Gehäuses 3 liegt die linke Kantenpartie 662 der Deckplatte 66. Die genannte Auflage der Deckplatte 66 erfolgt unter Zwischenlage eines länglichen Abdichtelementes 47, welcher sich entlang der Kante 931 des ersten zur Wand 5 senkrecht stehenden Reflektors 93 erstreckt.The in Fig. 4 The left vertical reflector 93 of the channel 30 is located at a distance from the left side wall 72 of the housing 3. The in Fig. 4 Left edge portion 67 of the cover plate 66 is designed so wide that it bridges the distance between the side wall 72 and the reflector 93. In the region of the inner upper edge of the respective side wall 71 or 72 and in the transverse wall 6 of the housing 3, a fold 73 is executed, whose longitudinal direction coincides with the longitudinal direction of the respective edge. This fold 73 opens against the interior of the housing 3 and against upward and the fold 73 has a horizontal edge 731 and a vertical edge 732 on. On the horizontal flank 731 of the fold 73 in the left side wall 72 of the housing 3 is the left edge portion 662 of the cover plate 66. The said support of the cover plate 66 takes place with the interposition of an elongated sealing member 47 which extends along the edge 931 of the first to the wall 5 vertical reflector 93 extends.

Das Abdichtelement 47 hat einen im wesentlichen L-förmigen Querschnitt. Der freie Endbereich des horizontalen Schenkels 471 dieses L-Elementes 47 liegt zwischen der oberen Kante 931 des Reflektors 93 und der Unterseite der Deckplatte 66. Von der Unterseite und in einem Abstand vom genannten freien Ende dieses L-Schenkels 471 hängt ein streifenförmiger Anschlag 472 herab, welcher an der Aussenfläche des Reflektors 93 anliegen kann. Der Bereich des anderen und vertikal verlaufenden L-Schenkel 473 des Abdichtelementes 47 liegt an der Stirnfläche der zweiten Kante 662 dieses Randes 67 der Deckplatte 66 an. Dieser Plattenrand 67 liegt über diesen Bereich des zweiten L-Schenkels 473 im Falz 73 dieser Seitenwand 72 des Gehäuses 3 auf. Der genannte Falz 73 ist auch in der oberen Kante der Querwand 6 des Gehäuses 3 ausgeführt, sodass der vorne liegende Rand der Deckplatte 66 in diesem Falz 73 der Querwand 6 (Fig. 7) ebenfalls liegt.The sealing member 47 has a substantially L-shaped cross section. The free end portion of the horizontal leg 471 of this L-element 47 lies between the upper edge 931 of the reflector 93 and the underside of the cover plate 66. From the bottom and at a distance from said free end of this L-leg 471 hangs a strip-shaped stop 472 down , which can rest on the outer surface of the reflector 93. The region of the other and vertically extending L-leg 473 of the sealing element 47 bears against the end face of the second edge 662 of this edge 67 of the cover plate 66. This plate edge 67 rests on this region of the second L-leg 473 in the fold 73 of this side wall 72 of the housing 3. Said fold 73 is also executed in the upper edge of the transverse wall 6 of the housing 3, so that the front edge of the cover plate 66 in this fold 73 of the transverse wall 6 (FIG. Fig. 7 ) is also located.

In der oberen Mündung des Nebenkanals 24 im Gehäuse 3 der Einrichtung gemäss Fig. 4 befindet sich ein Gitter 68, welches diese Mündung überdeckt und die Strömung von Luft durch diese Mündung des Gehäuses 3 dennoch erlaubt. Die in Fig. 4 rechts abgebildete Kante des Gitters 68 liegt im Falz 73 der rechts abgebildeten Seitenwand 71 des Gehäuses 3 und zwar unter Zwischenlage eines weiteren Abdichtelementes 48. Der Querschnitt dieses dritten Abdichtelementes 48 ist L-förmig, sodass dieses Abdichtelement 48 eine horizontale Flanke 481 und eine vertikale Flanke 482 aufweist. Dieses dritte Abdichtelement 48 ist im Falz 73 so angeordnet, dass sein Horizontalschenkel 481 auf dem Horizontalschenkel 731 des Falzes 73 liegt und dass der Vertikalschenkel 482 des Abdichtelementes 48 dem Vertikalschenkel 732 des Falzes 73 gegenübersteht. Der gegenüberliegende Rand des Gitters 68 ist auf dem zweiten horizontalen Kreuzschenkel des ersten Abdichtelementes 46 abgestützt. Es versteht sich, dass der vorne liegende Rand des Gitters 68 im Falz 73 der Querwand 6 ruht bzw. ruhen kann.In the upper mouth of the secondary channel 24 in the housing 3 of the device according to Fig. 4 There is a grid 68 which covers this mouth and the flow of air through this mouth of the housing 3 still allowed. In the Fig. 4 The right edge of the grid 68 is located in the fold 73 of the right side wall 71 of the housing 3, with the interposition of a further Abdichtelementes 48. The cross section of this third Abdichtelementes 48 is L-shaped, so that this sealing member 48 has a horizontal edge 481 and a vertical edge 482 has. This third sealing element 48 is arranged in the fold 73 such that its horizontal leg 481 lies on the horizontal leg 731 of the fold 73 and that the vertical leg 482 of the sealing element 48 the vertical leg 732 of the fold 73 faces. The opposite edge of the grid 68 is supported on the second horizontal cross leg of the first sealing member 46. It is understood that the front edge of the grid 68 in the fold 73 of the transverse wall 6 can rest or rest.

Fig. 5 zeigt eine weitere Ausführung des Fensters 1. Jener Teil dieses Fensters 1, welcher für den Durchlass von Luft bestimmt ist, weist anstelle einer fest eingebauten Platte einen Fensterflügel 69 auf, welcher im Rahmen 22 schwenkbar gelagert ist. Dieser Fensterflügel 69 kann als ein Kippfenster oder als ein in einer horizontalen Ebene schwenkbarer Flügel ausgeführt sein. Die Verwendung des Fensterflügels 69 bietet den Vorteil, dass man den Luftdurchlass durch das Fenster 1, beispielsweise bei Kälte, wahlweise unterbrechen kann. Wenn der Fensterflügel 69 an der dem Inneren des Raumes 42 zugewandten Innenseite des Fensters 1 schwenkbar angebracht ist, dann kann das Fenster 1 mit einem nachstehend beschriebenen Ventilator gleichzeitig ausgerüstet sein. Fig. 5 shows a further embodiment of the window 1. That part of this window 1, which is intended for the passage of air, instead of a permanently installed plate has a sash 69, which is pivotally mounted in the frame 22. This window sash 69 can be designed as a tilting window or as a wing pivotable in a horizontal plane. The use of the window sash 69 offers the advantage that it is possible to interrupt the passage of air through the window 1, for example when it is cold. When the sash 69 is pivotally mounted on the inside of the room 42 facing inside of the window 1, then the window 1 may be equipped with a fan described below simultaneously.

Fig. 6 zeigt in einem vertikalen Schnitt eine weitere Ausführungsmöglichkeit der vorliegenden Einrichtung. Der Lichtführkanal 50 weist ebenfalls einen äusseren Abschnitt 51 und einen inneren Abschnitt 52 auf. Der äussere Abschnitt 51 dieses Lichtleitkanals 50 ist praktisch gleich ausgeführt wie der äussere Abschnitt 31 des Lichtleitkanals 30 in Fig. 2. Fig. 6 shows in a vertical section another embodiment of the present device. The light guide channel 50 also has an outer portion 51 and an inner portion 52. The outer portion 51 of this Lichtleitkanals 50 is performed practically the same as the outer portion 31 of the Lichtleitkanals 30 in Fig. 2 ,

Der innere Abschnitt 52 des Kanals 50 hat einen Querschnitt, welcher dem Querschnitt des Fensters 1 entspricht. Im vorliegenden Fall hat der innere Abschnitt 52 des Kanals 50 einen rechteckförmigen Querschnitt, dessen längere Seiten horizontal verlaufen. Dieser innere Kanalabschnitt 52 ist durch zwei horizontal angeordnete Reflektorelemente 53 und 54 und durch zwei vertikal verlaufende Reflektorelemente 55 begrenzt, von welchen sich je eines zwischen den Endkanten der horizontalen Reflektoren 53 und 54 erstreckt. Die vertikalen Reflektoren 55 definieren die Seiten bzw. Seitenwände eines Rechteckes. Dieser zweite Kanalinnenabschnitt 52 ist in der Wandöffnung 8 eingesetzt und die Austrittspartie 45 desselben ist dem Lichtdurchlassteil 21 des Fensters 1 so zugeordnet, wie dies im Zusammenhang mit dem Lichtleitkanal 30 (Fig. 4) beschrieben ist. Die Reflektoren 53 bis 55 dieses zweiten Kanalabschnittes 52 und die wandparallelen Reflektoren 91 und 92 haben die Form von viereckigen Platten. Die Kontur der zur Wand 5 senkrecht stehenden Reflektoren 93 und 94 ist derart, dass sich diese seitlichen Reflektoren 93 und 94 von der Kanaleintrittsmündung 70 bis zum Anfang 541 des zweiten Kanalabschnittes 52 erstrecken.The inner portion 52 of the channel 50 has a cross section which corresponds to the cross section of the window 1. In the present case, the inner portion 52 of the channel 50 has a rectangular cross-section, the longer sides are horizontal. This inner channel section 52 is bounded by two horizontally disposed reflector elements 53 and 54 and by two vertically extending reflector elements 55, one of which extends between the end edges of the horizontal reflectors 53 and 54. The vertical reflectors 55 define the sides of a rectangle. This second channel inner portion 52 is inserted into the wall opening 8 and the outlet portion 45 thereof is associated with the light transmission portion 21 of the window 1, as in connection with the Lichtleitkanal 30 (Fig. Fig. 4 ) is described. The reflectors 53 to 55 of this second channel section 52 and the wall-parallel reflectors 91 and 92 have the shape of quadrangular plates. The contour of the reflectors 93 and 94, which are perpendicular to the wall 5, is such that these lateral reflectors 93 and 94 extend from the channel inlet orifice 70 to the beginning 541 of the second channel section 52.

Es ist ein Ventilator 49 vorgesehen, welcher der Oeffnung 43 in der Luftdurchlassplatte 39 zugeordnet ist. Im dargestellten Fall ist der Ventilator 49 der Aussenseite der Luftdurchlassplatte 39 zugeordnet und er befindet sich in der unteren Hälfte dieser Platte 39. Der Ventilator 49 kann die Luftströmung zwischen dem Innenraum 42 und der Umgebung des Gehäuses 3 unterstützen.There is provided a fan 49 which is associated with the opening 43 in the air passage plate 39. In the illustrated case, the fan 49 is associated with the outside of the air passage plate 39 and it is located in the lower half of this plate 39. The fan 49, the air flow between the interior 42 and the environment of the housing 3 support.

Die Längsachse des äusseren Kanalabschnittes 51 verläuft hinsichtlich einer Vertikalen schräg, und zwar etwa so, wie dies im Zusammenhang mit Fig. 2 beschrieben ist. Die Längsachse des inneren Kanalabschnittes 52 verläuft hinsichtlich der Vertikalen jedoch senkrecht. Zwischen der unteren Kante 921 des zweiten, d.h. des von der Wand 5 entfernt liegenden Reflektors 92 im oberen Kanalabschnitt 51 und der inneren Kante 541 des unteren Reflektors 54 im zweiten Kanalabschnitt 52 würde normalerweise eine Lücke klaffen. Um dies zu vermeiden, ist ein Ueberbrückungsreflektor 60 vorgesehen, welcher sich zwischen den genannten Kanten der Reflektoren 54 und 92 erstreckt. In der dazu querliegenden Richtung erstreckt sich dieser Ueberbrückungsreflektor 60 zwischen den seitlichen Reflektoren 93 und 94 des Kanals 50.The longitudinal axis of the outer channel portion 51 is inclined with respect to a vertical, approximately as in connection with Fig. 2 is described. However, the longitudinal axis of the inner channel portion 52 is perpendicular with respect to the vertical. Between the lower edge 921 of the second, ie, the reflector 92 remote from the wall 5 in the upper channel portion 51 and the inner edge 541 of the lower reflector 54 in the second channel portion 52 would normally gap a gap. To avoid this, a bridging reflector 60 is provided which extends between said edges of the reflectors 54 and 92. In the transverse direction, this bridging reflector 60 extends between the side reflectors 93 and 94 of the channel 50.

Die in Fig. 6 dargestellte Ausführungsform der vorliegenden Einrichtung weist ebenfalls den bereits beschriebenen Aufsatz 25 auf, welcher in Fig. 6 in einem vertikalen Schnitt dargestellt ist. Das in Fig. 6 dargestellte Gehäuse 3 weist eine horizontal verlaufende Bodenwand 13, welche der im Erdreich liegenden Stirnseite des U-förmigen Grundkörpers des Gehäuses 3 zugeordnet ist. Die Aussenseite der Wände 6, 7 und 13 des Gehäuses 3 ist mit einem wärmeisolierenden Material 58 versehen. Dieses kann ein Wärmedämmaterial sein oder diese Materialschicht kann aus Gipsplatten bestehen. Das wärmedämmende Material 58 bildet dabei eine verhältnismässig dicke Schicht an der Aussenseite der vertikal verlaufenden Wände 6 und 7 des Gehäuses 3. Um zu verhindern, dass Regenwasser in das wärmedämmende Material 58 am Gehäuse 3 eindringt, sind die Abmessungen des Aufsatzes 25 so gewählt, dass dieser die Schichten 58 aus dem Isolierungsmaterial übergreift und dadurch überdeckt.In the Fig. 6 illustrated embodiment of the present device also has the above-described article 25, which in Fig. 6 in one vertical section is shown. This in Fig. 6 shown housing 3 has a horizontally extending bottom wall 13, which is assigned to the lying in the ground end face of the U-shaped main body of the housing 3. The outside of the walls 6, 7 and 13 of the housing 3 is provided with a heat-insulating material 58. This may be a thermal insulation material or this material layer may consist of gypsum boards. The heat-insulating material 58 forms a relatively thick layer on the outside of the vertically extending walls 6 and 7 of the housing 3. In order to prevent rainwater from penetrating into the heat-insulating material 58 on the housing 3, the dimensions of the attachment 25 are selected such that this overlaps the layers 58 of the insulating material and thereby covered.

Die Aussenseite der Hauswand 5 ist ebenfalls mit einer Schicht 59 aus einem Wärmedämmaterial oder aus Gipsplatten belegt. Diese Isolierungsschicht 59 vergrössert die Dicke des Mauerwerkes 5, wobei je nach Situation diese Isolierungsschicht 59 unterschiedliche Dicke aufweisen kann. Folglich muss die Breite der dieser Isolierungsschicht 59 zugeordneten Randpartie 64 des Aufsatzes 25 dementsprechend gewählt werden. Zwischen der Aussenkante 271 der gerade genannten Randpartie 64 des Aufsatzes 25 und der Aussenfläche der Isolierungsschicht 59 an der Wand 5 ist ein Spalt vorhanden. Um zu erreichen, dass möglichst wenig Regenwasser durch diesen Spalt bis zur Wandöffnung 8 gelangt, ist es zweckdienlich, die Breite des Randes 64 so zu wählen, dass die freie Kante dieses Randes 64 in die Aussenseite der Isolierungsschicht 59 eingedrückt ist.The outside of the house wall 5 is also covered with a layer 59 of a thermal insulating material or plasterboard. This insulating layer 59 increases the thickness of the masonry 5, wherein depending on the situation, this insulating layer 59 may have different thickness. Consequently, the width of this insulating layer 59 associated edge portion 64 of the article 25 must be selected accordingly. Between the outer edge 271 of the just mentioned edge portion 64 of the cap 25 and the outer surface of the insulating layer 59 on the wall 5, a gap is present. In order to ensure that the least possible rainwater passes through this gap to the wall opening 8, it is expedient to choose the width of the edge 64 so that the free edge of this edge 64 is pressed into the outside of the insulating layer 59.

Die in Fig. 7 abgebildete Ausführungsform der vorliegenden Einrichtung weist einen Lichtkanal bzw. einen Lichtschacht 80 auf, welcher die Richtung des dem Innenraum 42 zugeführten Lichts um 90 Grad umlenkt. Zu diesem Zweck weist der Kanal 80 zwei Abschnitte 11 und 82, welche hintereinander geschaltet sind. Der erste bzw. äussere Abschnitt des Lichtkanals 80 ist im wesentlichen gleich ausgeführt wie der Lichtkanal 11 der Einrichtung gemäss Fig. 1, dessen Längsachse ebenfalls vertikal verläuft. Die obere Mündung 70 dieses ersten bzw. äusseren Kanalabschnittes 11 ist mit Hilfe der Deckplatte 66 zugedeckt, welche im Zusammenhang mit Fig. 4 beschrieben ist. Die Längsachse des zweiten Kanalabschnittes 82 verläuft dagegen horizontal, d.h. senkrecht zur Längsachse des ersten Kanalabschnittes 11. Ein Teil des zweiten bzw. inneren Kanalabschnittes 82 befindet sich in der Oeffnung 8 der Wand 5. Die Licht-Austrittsmündung 45 des inneren Kanalabschnittes 82 ist mit der Innenkante der Wandöffnung 8 praktisch bündig. Es versteht sich jedoch, dass der innere Kanalabschnitt 82 auch so ausgeführt sein kann, dass ein Abschnitt desselben in den Innenraum 42 hineinragt.In the Fig. 7 illustrated embodiment of the present device has a light channel or a light well 80, which deflects the direction of the light supplied to the interior 42 by 90 degrees. For this purpose, the channel 80 has two sections 11 and 82, which are connected in series. The first and outer portions of the light channel 80 are substantially equal executed as the light channel 11 of the device according to Fig. 1 whose longitudinal axis is also vertical. The upper mouth 70 of this first and outer channel portion 11 is covered by means of the cover plate 66, which in connection with Fig. 4 is described. The longitudinal axis of the second channel portion 82, however, extends horizontally, ie perpendicular to the longitudinal axis of the first channel portion 11. A portion of the second or inner channel portion 82 is located in the opening 8 of the wall 5. The light exit port 45 of the inner channel portion 82 is connected to the Inner edge of the wall opening 8 practically flush. It is understood, however, that the inner channel portion 82 may also be configured such that a portion thereof projects into the inner space 42.

Der zweite bzw. innere Abschnitt 82 des Lichtkanals 80 weist einander gegenüberstehende und vertikal verlaufende Seitenwände 83 auf, von welchen in Fig. 7 nur die hinten liegende Seitenwand 83 ersichtlich ist. Die jeweilige Seitenwand 83 weist eine obere und horizontal verlaufende Kante 831 auf, welche sich praktisch von der Austrittsmündung 45 für das Licht bis zur unteren Kante 921 des zweiten Reflektors 92 im äusseren Abschnitt 11 des Kanals 80 erstreckt. Innerhalb der Breite des äusseren Kanalabschnittes 11 stösst diese obere Horizontalkante 831 an die untere horizontale Kante 931 des darüber liegenden seitlichen Reflektors 93 an. Es versteht sich, dass auch diese Seitenwände 83 des inneren Kanalabschnittes 82 reflektierend sein können.The second or inner portion 82 of the light channel 80 has opposing and vertically extending side walls 83, of which in Fig. 7 only the rear side wall 83 can be seen. The respective side wall 83 has an upper and horizontally extending edge 831 which extends practically from the exit mouth 45 for the light to the lower edge 921 of the second reflector 92 in the outer portion 11 of the channel 80. Within the width of the outer channel section 11, this upper horizontal edge 831 abuts against the lower horizontal edge 931 of the overlying lateral reflector 93. It is understood that these side walls 83 of the inner channel section 82 can be reflective.

Jener Abschnitt der gegenüberliegenden, d.h. der unteren Längskante 832 der Seitenwand 83, welcher in der Wandöffnung 8 liegt, verläuft ebenfalls horizontal. An diesen horizontalen Abschnitt 832 schliesst sich ein zusammengesetzter Abschnitt der unteren Seitenwandkante 832 an, welcher sich unter dem äusseren Abschnitt 11 des Lichtkanals 80 befindet. Dieser zusammengesetzter Verlauf ist durch die Konstruktion der unteren Wand bestimmt, weil die Ränder der horizontalen und der vertikalen Bestandteile der Kanalabschnitte 11 und 82 miteinander verbunden sind.That portion of the opposite, ie the lower longitudinal edge 832 of the side wall 83, which lies in the wall opening 8, also extends horizontally. At this horizontal portion 832 joins a composite portion of the lower side wall edge 832, which is located below the outer portion 11 of the light channel 80. This composite course is determined by the construction of the lower wall, because the edges of the horizontal and the vertical components of the channel sections 11 and 82 are interconnected.

Dieser zweite bzw. innere Abschnitt 82 des Lichtkanals 80 weist ferner einander gegenüberliegende und horizontal verlaufende Wände 84 und 85 auf. Der grössere Abschnitt der oberen Horizontalwand 84 befindet sich in der Wandöffnung 8. Die Innenkante 841 dieser Horizontalwand 84 stösst mit der unteren Kante 911 der ersten Vertikalwand 91 des äusseren Kanalabschnittes 11 zusammen. Die untere Horizontalwand 85 hat einen ersten Abschnitt 832, welcher der oberen Horizontalwand 84 gegenüberliegt und dessen innere Kante 851 praktisch unterhalb der erwähnten Innenkante 911 liegt.This second or inner portion 82 of the light channel 80 further comprises opposing and horizontally extending walls 84 and 85. The larger portion of the upper horizontal wall 84 is located in the wall opening 8. The inner edge 841 of this horizontal wall 84 abuts with the lower edge 911 of the first vertical wall 91 of the outer channel portion 11 together. The lower horizontal wall 85 has a first portion 832 which is opposite the upper horizontal wall 84 and the inner edge 851 is practically below the mentioned inner edge 911.

Die untere Horizontalwand 85 hat ferner zwei weitere und hintereinander angeordnete Abschnitte 86 und 87, welche sich an den ersten Abschnitt 85 anschliessen. Die Längen dieser zwei weiteren Wandabschnitte 86 und 87 können gleich sein. Unterschiedlich ist dagegen die Winkellage dieser Wandabschnitte 86 und 87 gegenüber einer Horizontalen. Der zweite Wandabschnitt 86 schliesst mit der Horizontalen einen Winkel von etwa 20 Grad. Der dritte Wandabschnitt 87 schliesst mit der Horizontalen einen Winkel von etwa 60 Grad. Zumindest die Innenfläche aller Bestandteile des inneren Kanalabschnittes 82 ist reflektierend. Mit Hilfe der so angeordneten Wandabschnitte 86 und 87, welche dem äusseren Kanalabschnitt 11 gegenüberstehen, gelingt es, das Licht, welches durch den äusseren Abschnitt 11 in das Innere des Kanals 80 gelangte um 90 Grad umzulenken, damit es durch die Austrittsmündung 45 aus dem inneren Kanalabschnitt 80 in den Innenraum 42 gelangen kann. Die Lage der geneigt angeordneten Wandabschnitte 86 und 87 bestimmt auch den Verlauf der unteren Kante 832 der Seitenwände 83 dieses unteren Kanalabschnittes 82.The lower horizontal wall 85 also has two further and successively arranged sections 86 and 87, which adjoin the first section 85. The lengths of these two further wall sections 86 and 87 may be the same. By contrast, the angular position of these wall sections 86 and 87 with respect to a horizontal is different. The second wall portion 86 closes with the horizontal an angle of about 20 degrees. The third wall portion 87 closes with the horizontal an angle of about 60 degrees. At least the inner surface of all components of the inner channel section 82 is reflective. With the help of the thus arranged wall sections 86 and 87, which face the outer channel section 11, it is possible to redirect the light, which passed through the outer section 11 into the interior of the channel 80 by 90 degrees, so that it through the outlet opening 45 from the inner Channel section 80 can get into the interior 42. The location of the inclined wall sections 86 and 87 also determines the course of the lower edge 832 of the side walls 83 of this lower channel section 82.

Jener Teil des inneren Kanalabschnittes 82, welcher in der Oeffnung 8 eingesetzt ist, ragt über eine bestimmte Länge in das Innere des Gehäuses 3 hinein, sodass die innere Kante 841 des oberen Reflektors 84 des zweiten Kanalabschnittes 82 und somit auch der der Wand 5 näher liegende Reflektor 91 des ersten Kanalabschnittes 11 sich in einem Abstand von der Aussenfläche 14 der Wand 5 befinden. Dieser Abstand ist grösser als die Dicke der Wandisolation 59, sodass es einen Spalt 74 zwischen dem ersten wandparallelen Reflektor 91 und der Wandisolation 59 gibt. Der der Wand 5 zugewandte Rand 663 der lichtdurchlässigen Deckplatte 66 liegt auf dem oberen Rand 912 des zuletzt genannten Reflektors 91 auf. Der gegenüberliegende Rand 664 der Deckplatte 66 liegt auf dem oberen Rand des gegenüberliegenden parallelen Reflektors 92 sowie im inneren des Falzes 73 des oberen Randes der Querwand 6.That part of the inner channel section 82, which is inserted in the opening 8, protrudes over a certain length into the interior of the housing 3, so that the inner edge 841 of the upper reflector 84 of the second channel section 82, and thus also the reflector 91 of the first channel section 11 closer to the wall 5, are located at a distance from the outer surface 14 of the wall 5. This distance is greater than the thickness of the wall insulation 59, so that there is a gap 74 between the first wall-parallel reflector 91 and the wall insulation 59. The wall 5 facing edge 663 of the translucent cover plate 66 rests on the upper edge 912 of the latter reflector 91. The opposite edge 664 of the cover plate 66 lies on the upper edge of the opposite parallel reflector 92 and in the interior of the fold 73 of the upper edge of the transverse wall. 6

Um zu verhindern, dass Regenwasser in den Spalt 74 gelangt, ist ein Schutzblech 75 vorgesehen. Dieses Schutzblech 75 hat einen etwa L-förmigen Querschnitt mit den Schenkeln 76 und 77. Der vertikal verlaufende L-Schenkel 76 liegt möglichst dicht an der Aussenfläche der Wandisolation 59. Die Breite des horizontalen Schenkels 77 dieses Schutzbleches 75 ist grösser als die Breite des genannten Spaltes 74. Folglich kann dieses Schutzblech 75 über dem Spalt 74 so angeordnet sein, dass die freie Randpartie des horizontalen L-Schenkels 77 auf dem anliegenden Rand 663 der Deckplatte 66 aufliegt. Um diese Lage des Schutzbleches 75 sicherzustellen, ist eine Leiste 78, beispielsweise eine Holzleiste, zwischen der Aussenseite der Isolation 59 der Hauswand 5 und der Aussenseite des anliegenden Reflektors 91 bzw. dem hier liegenden Rand 663 der Deckplatte 66 angeordnet und befestigt. Die Breite der Leiste 78 gleicht praktisch der Breite des Spaltes 74. Die obere Fläche dieser Leiste 78 ist mit der oberen Fläche der Deckplatte 66 bündig und der betreffende Teil der Breite des horizontalen L-Schenkels 77 liegt auf dieser Oberfläche der Leiste 78 auf.In order to prevent rainwater from entering the gap 74, an apron 75 is provided. This fender 75 has an approximately L-shaped cross section with the legs 76 and 77. The vertically extending L-leg 76 is as close as possible to the outer surface of the wall insulation 59. The width of the horizontal leg 77 of this fender 75 is greater than the width of said Gap 74. Consequently, this fender 75 may be disposed above the gap 74 so that the free edge portion of the horizontal L-leg 77 rests on the abutting edge 663 of the cover plate 66. To ensure this position of the mudguard 75, a strip 78, for example, a wooden strip, between the outside of the insulation 59 of the house wall 5 and the outside of the adjacent reflector 91 and the edge 663 of the cover plate 66 located here and arranged. The width of the bar 78 is virtually equal to the width of the gap 74. The upper surface of this bar 78 is flush with the upper surface of the cover plate 66 and the relevant part of the width of the horizontal L-leg 77 rests on this surface of the bar 78.

Ein allfälliges Eindringen von Wasser in den sich unter der Deckplatte 66 befindlichen Raum verhindern weitere Abdichtelemente 47 und 100, welche der Deckplatte 66 zugeordnet sind. Das erstgenannte Abdichtelement 47 ist im wesentlichen gleich ausgebildet wie das Abdichtelement 47 in Fig. 4. Dieses Abdichtelement 47 ist der Deckplatte 66 auch in gleicher Weise zugeordnet. Das Abdichtelement 47 befindet sich im Falz 73 der Querwand 6 sowie der Seitenwände 71 und 72. Das andere Abdichtelement 100 ist zwischen der Deckplatte 66 und dem wandnahen Reflektor 91 angeordnet und es hat einen im wesentlichen T-förmigen Querschnitt. Ein Balkenteil dieses T-Querschnittes weist zwei Schenkel 101 und 102 auf, welche im dargestellten Fall vertikal verlaufen. Ein Stehteil 103 der T-Form 100 schliesst sich etwa in der Mitte der Länge des Balkenteiles, d.h. zwischen den Schenkeln 101 und 102 an den Balkenteil an. Dieser Stehteil 103 steht senkrecht zu den genannten T-Schenkeln 101 und 102, zwischen welchen sich seine Anschlussstelle an diese befindet.A possible ingress of water in the space located below the cover plate 66 prevent further sealing elements 47 and 100, which are associated with the cover plate 66. The former sealing member 47 is in formed substantially the same as the sealing member 47 in Fig. 4 , This sealing element 47 is also associated with the cover plate 66 in the same way. The sealing member 47 is located in the fold 73 of the transverse wall 6 and the side walls 71 and 72. The other sealing member 100 is disposed between the cover plate 66 and the near-wall reflector 91 and it has a substantially T-shaped cross-section. A beam portion of this T-section has two legs 101 and 102, which are vertical in the illustrated case. A standing part 103 of the T-shape 100 closes approximately in the middle of the length of the beam part, ie between the legs 101 and 102 to the beam part. This standing part 103 is perpendicular to said T-legs 101 and 102, between which its junction is located at this.

Der obere T-Schenkel 101 befindet sich zwischen der vertikal verlaufenden Stirnfläche der hier liegenden Randpartie 663 der Deckplatte 66 und der Abstandsleiste 78. Der Stehteil 103 befindet sich zwischen der Unterseite der genannten Randpartie 663 und der Oberkante 912 des Reflektors 91. Der untere Schenkel 102 der T-Dichtung 100 liegt an der der Wand 5 zugewandten Seite des Reflektors 91. Eine geeignete und an sich bekannte Dichtmasse 105 kann die Fugen zischen dem oberen Rand der Deckplatte 66 und der hier liegenden Kante des betreffenden Abdichtelementes 47 und 100 überdecken und wasserdicht machen.The upper T-leg 101 is located between the vertically extending end face of the here lying edge portion 663 of the cover plate 66 and the spacer bar 78. The standing portion 103 is located between the underside of said edge portion 663 and the upper edge 912 of the reflector 91. The lower leg 102nd The T-seal 100 is located on the side facing the wall 5 of the reflector 91. A suitable and known sealing compound 105, the joints hiss the top of the cover plate 66 and the lying here edge of the respective sealing member 47 and 100 cover and make waterproof ,

Die in Fig. 8 abgebildete Einrichtung ist so ausgeführt, dass die Deckplatte 66 weder auf den oberen Rändern der Reflektoren 91 und 92 des Lichtkanals noch auf dem oberen Rand des Gehäuses 3 aufliegt. Zu diesem Zweck ist je eine Leiste 79, beispielsweise aus Holz, im Falz 73 der Querwand 6 und der Seitenwände 71 und 72 angeordnet, deren Höhe grösser ist als die Tiefe des Falzes 73, sodass die obere Partie dieser zweiten Leiste 79 aus dem Falz 73 hervorsteht. Der obere Rand 912 des ersten wandparallelen Reflektors 91 ist dementsprechend höher angeordnet, sodass die Stirnfläche dieses Randes 912 auf derselben Höhe liegt wie die Oberfläche der zweiten Leiste 79. Auf diesem Rand 912 und auf der zweiten Leiste 79 liegt die Abdeckplatte 66 auf, sodass die Abdeckplatte 66 hinsichtlich des Gehäuses 3 bei der Einrichtung gemäss Fig. 8 höher angeordnet ist als dies in Fig. 7 der Fall ist. Dies ermöglicht, die Abdeckplatte 66 so lang bzw. so breit auszuführen, dass die Stirnfläche der zweiten bzw. von der Wand 5 entfernt liegenden Randpartie 664 derselben hinter der Aussenfläche der Querwand 6 des Gehäuses 3 liegt. In dieser Weise kann das Regenwasser durch diese Abdeckplatte 66 bis in einen sicheren Abstand vom Gehäuse 3 weggeleitet werden. Entsprechendes gilt auch für jene Randpartien der Deckplatte 66, welche senkrecht zur genannten Randpartie 664 verlaufen und welche die Seitenwände 71 und 72 des Gehäuses 3 in einem solchen Fall überhängen.In the Fig. 8 The illustrated device is designed so that the cover plate 66 rests neither on the upper edges of the reflectors 91 and 92 of the light channel nor on the upper edge of the housing 3. For this purpose, each bar 79, for example made of wood, in the fold 73 of the transverse wall 6 and the side walls 71 and 72 are arranged, whose height is greater than the depth of the fold 73, so that the upper part of this second bar 79 from the fold 73rd protrudes. The upper edge 912 of the first wall-parallel reflector 91 is accordingly arranged higher, so that the end face of this edge 912 is at the same height As the surface of the second strip 79. On this edge 912 and on the second bar 79, the cover plate 66 is located so that the cover plate 66 with respect to the housing 3 in the device according to Fig. 8 is arranged higher than this in Fig. 7 the case is. This makes it possible to make the cover plate 66 so long or so wide that the end face of the second edge part 664 or of the wall 5 remote from the wall 5 lies behind the outer face of the transverse wall 6 of the housing 3. In this way, the rainwater can be led away by this cover plate 66 to a safe distance from the housing 3. The same applies to those edge parts of the cover plate 66, which run perpendicular to said edge portion 664 and which overhang the side walls 71 and 72 of the housing 3 in such a case.

Fig. 9 und 10 zeigen vergrössert zwei Ausschnitte aus Fig. 8. Fig. 9 zeigt vergrössert jenen Ausschnitt aus Fig. 8, welcher die links abgebildete Randpartie 663 der Deckplatte 66 umfasst. Dieser Plattenrandpartie 663 ist ein erstes Abdichtelement 175 zugeordnet, welches ein aus zwei "L" zusammengesetztes Profil hat. Der erste L-Teil umfasst Schenkel 1751 und 1752 und der zweite L-Teil umfasst Schenkel 1753 und 1754. Die erste L-Hälfte 1751 und 1752 entspricht dem L-Profil 75 aus Fig. 7 und sie ist auch gleich angeordnet. Der horizontale Schenkel 1751 dieser ersten L-Hälfte ist jedoch so kurz ausgeführt, dass dieser Schenkel 1751 noch vor der Stirnfläche dieses Deckelrandes 663 endet. An dieses Ende des Horizontalschenkels 1751 schliesst sich das obere Ende des Vertikalschenkels 1754 an und dieser Schenkel 1754 ist der Stirnfläche dieses Deckelrandes 663 zugeordnet. Der horizontale Schenkel 1753 dieser zweiten Dichtungshälfte ist der Unterseite dieses Deckelrandes 663 zugeordnet.Fig. 9 and 10 show enlarged two sections Fig. 8 , Fig. 9 shows enlarged that section Fig. 8 , which comprises the edge portion 663 of the cover plate 66 shown on the left. This plate edge portion 663 is associated with a first sealing member 175 having a profile composed of two "L's". The first L-part includes legs 1751 and 1752 and the second L-part includes legs 1753 and 1754. The first L-half 1751 and 1752 corresponds to the L-profile 75 Fig. 7 and she is also arranged the same. However, the horizontal leg 1751 of this first L-half is made so short that this leg 1751 ends before the end face of this lid edge 663. At this end of the horizontal leg 1751 adjoins the upper end of the vertical leg 1754 and this leg 1754 is associated with the end face of this lid edge 663. The horizontal leg 1753 of this second sealing half is assigned to the underside of this lid edge 663.

In diesem Bereich der vorliegenden Einrichtung ist noch ein weiteres Abdichtungselement 88 angeordnet, welches einen Z-förmigen Querschnitt aufweist. Der horizontal angeordnete Schenkel 881 dieses Z-Profils 8 liegt zwischen dem Horizontalschenkel 1753 des Doppel-L-Profils 175 und dem oberen Rand 912 des Reflektors 91. Der untere Vertikalschenkel 882 des Z-Gliedes 88 liegt an der Innenseite des Reflektors 91 an. Der obere Vertikalschenkel 883 des Z-Gliedes 88 ist der Rück- bzw. Innenseite des Vertikalschenkels 1754 des Doppel-L-Gliedes 175 zugeordnet.In this area of the present device, yet another sealing element 88 is arranged, which has a Z-shaped cross section. The horizontally arranged leg 881 of this Z-profile 8 lies between the horizontal leg 1753 of the double-L-profile 175 and the upper one Edge 912 of the reflector 91. The lower vertical leg 882 of the Z-member 88 abuts against the inside of the reflector 91. The upper vertical leg 883 of the Z member 88 is associated with the rear or inside of the vertical leg 1754 of the double-L member 175.

Fig. 10 zeigt vergrössert jenen Ausschnitt aus Fig. 8, welcher die rechts abgebildete Randpartie 664 der Deckplatte 66 umfasst. Dieser Plattenrandpartie 664 ist ein Abdichtelement 89 zugeordnet, welches einen Tau-förmigen Querschnitt aufweist. Wegen der Aehnlichkeit von Tau mit T, werden bestimmte Bestandteile der Tau-Form gleich bezeichnet wie die entsprechenden Bestandteile des Abdichtelementes 100 mit dem T-förmigen Querschnitt (Fig. 7). An die freie Endpartie des Stehteiles 103 schliesst sich ein weiterer Schenkel bzw. ein Streifen 104 an, welcher zum Stehteil 103 senkrecht steht und welcher zum unteren Vertikalschenkel 102 parallel verläuft.Fig. 10 shows enlarged that section Fig. 8 , which comprises the edge portion 664 of the cover plate 66 shown on the right. This Plattenrandpartie 664 is associated with a sealing member 89 which has a tau-shaped cross-section. Because of the similarity of tau with T, certain components of the tau-shape are the same as the corresponding components of the sealing element 100 with the T-shaped cross-section ( Fig. 7 ). At the free end portion of the standing part 103 is followed by another leg or a strip 104, which is perpendicular to the standing part 103 and which is parallel to the lower vertical leg 102.

Der obere Vertikalschenkel 101 der Tau-Abdichtung 89 ist der Stirnfläche dieser Randpartie 664 der Deckplatte 66 zugeordnet. Die Fuge zwischen diesen kann mit einer geeigneten Dichtmasse 105 ausgefüllt sein. Die Plattenrandpartie 664 liegt auf dem horizontal verlaufenden Stehteil 103 der Tau-Abdichtung 89. Der Tau-Schenkel 104 dieses Abdichtelementes 89 liegt an der Innenseite des hier angeordneten Reflektors 92 an. Der zweite T-Schenkel 102 kann als Abtropfkante dienen.The upper vertical leg 101 of the tau-seal 89 is associated with the end face of this edge part 664 of the cover plate 66. The gap between these can be filled with a suitable sealant 105. The plate edge portion 664 lies on the horizontally extending floor portion 103 of the dew-seal 89. The dew-leg 104 of this sealing element 89 abuts against the inside of the reflector 92 arranged here. The second T-leg 102 may serve as a drip edge.

Die vorliegende Einrichtung erlaubt auf einfache, energiesparende Weise die Ausleuchtung unterirdischer Räume mit Tageslicht. Es gibt keine bewegten Teile und somit kaum Verschleiss. Der Wartungsaufwand ist, je nach Ausführung, sehr gering bis vernachlässigbar. Es ist auch denkbar, für schlechte Lichtverhältnisse z.B. bei starker Bewölkung oder in der Dämmerung, die Beleuchtung mit Tageslicht mit einer Kunstlichtquelle im Schacht 2 zu mischen bzw. zu unterstützen.The present device allows in a simple, energy-saving way the illumination of underground spaces with daylight. There are no moving parts and therefore hardly any wear. The maintenance is, depending on the design, very low to negligible. It is also conceivable to mix or support the lighting with daylight with a source of artificial light in the shaft 2 for poor lighting conditions, for example during heavy cloud cover or at dusk.

Es versteht sich, dass die Merkmale, welche in der Beschreibung und in den Patentansprüchen im Zusammenhang mit den einzelnen Ausführungsformen offenbart sind, auch anders als beschrieben untereinander kombiniert werden können, um die gestellte Aufgabe zu lösen. Beispielsweise kann die Deckplatte 66 bei der Einrichtung gemäss Fig. 8 bis 10 schief wie bei der Einreichung gemäss Fig. 1 oder 6 angeordnet sein, usw.It is understood that the features which are disclosed in the description and in the patent claims in connection with the individual embodiments can also be combined with one another, as described, in order to achieve the stated object.
