Abstract

The casing of a roller shutter consists at least partially of box- type slats (12) which are fitted at the top and at the bottom with longitudinal slots (32, 34), are made of extruded aluminium and are interconnected by connecting rods (14) which engage in the slots displaceably and in a hooking manner and are essentially of C-shaped cross-section. The connecting rods (14) consist of transparent plastic. Ventilation openings (48) are arranged in the inner side walls (24) of the box-type slats (12) in such a way that they communicate with the top and/or bottom slots (32, 34) of the slats (12). By this means, with the casing raised in the ventilation position, on the one hand adequate ventilation is achieved and, on the other hand, excessive darkening of the room behind it is avoided. <IMAGE>

Description

Die Erfindung betrifft einen Rolladen, dessen Panzer wenig­stens zu einem Teil aus oben und unten mit längslaufenden Schlitzen versehenen kastenförmigen Rolladenstäben aus stranggepreßtem Aluminium besteht, die durch in die Schlit­ze verschieblich und verhakend eingreifende Verbindungsstä­be von im wesentlichen C-förmigen Querschnitt miteinander verbunden sind, wobei der Panzer in waagerechten Abstän­den aufeinanderfolgende Belüftungsöffnungen aufweist, die in der Ablaßendstellung des Panzers verschlossen sind.The invention relates to a roller shutter, the armor of which consists at least in part of box-shaped roller shutter bars made of extruded aluminum which are provided with longitudinal slots at the top and bottom and which are connected to one another by connecting bars of essentially C-shaped cross section which can be moved and hooked into the slots, the Tanks have successive ventilation openings at horizontal intervals, which are closed in the tank's deflation end position.

Derart gestaltete Rolläden sind in verschiedenen Ausführun­gen und aus verschiedenen Materialien bekannt. Bei einer ersten bekannten Ausführung (DE-GM 74 41 951) bestehen so­wohl die Rolladenstäbe als auch die mit Belüftungsöffnungen versehenen Verbindungsstäbe aus Kunststoff, wodurch ein sehr leichter Rolladenpanzer erhalten wird, der wenig Si­cherheit gegen Einbruch sowie auch gegen Schüsse im Fall von Attentatsversuchen bietet. Darüber hinaus dringt durch die als enge Spalte in den Verbindungsstäben ausgebildeten Belüfungsöffnungen bei in die Lüfungsstellung der Stäbe angehobenem Panzer nur wenig Licht, was die Verwendung des Rolladens als Sonnenschutz bei Tage erheblich einschränkt.Shutters designed in this way are known in various designs and from various materials. In a first known version (DE-GM 74 41 951), both the roller shutter rods and the connecting rods provided with ventilation openings are made of plastic, resulting in a very light roller shutter armor which offers little security against burglary and also against shots in the event of attempted attacks. In addition, only a little light penetrates through the ventilation openings formed as narrow gaps in the connecting rods when the shell is raised into the ventilation position of the rods, which considerably limits the use of the roller shutter as sun protection during the day.

Ein jüngerer bekannter Vorschlag für einen Rolladen der eingangs genannten Gestalt (DE-GM 79 16 727) sieht deshalb vor, die Verbindungsstäbe aus einem feinmaschigen Drahtgewe­be oder -gitter herzustellen, das aus Edelstahl, Aluminium oder verzinktem Metall besteht, während die kastenförmigen Rolladenstäbe wie bei der vorerwähnten Ausführung aus Kunst­stoff hergestellt sind. Hierdurch wird zwar die Lichtdurch­lässigkeit des angehobenen Panzers sowie auch die Belüftung verbessert; Diebstahlsicherheit und Schußsicherheit lassen jedoch nach wie vor zu wünschen übrig.A more recent known proposal for a roller shutter of the shape mentioned at the outset (DE-GM 79 16 727) therefore provides for the connecting rods to be made from a fine-meshed wire mesh or mesh made of stainless steel, aluminum or galvanized metal, while the box-shaped roller shutter rods as in the aforementioned version are made of plastic. This does improve the light transmission of the raised tank and also the ventilation; Theft security and bullet security still leave something to be desired.

Noch ein weiterer bekannter Rolladen der eingang genannten Gestalt verwendet kastenförmige Rolladenstäbe aus strangge­preßtem Aluminium, wodurch sich zwar ein verhältnismäßig schwerer und steifer und damit sowohl gegenüber Diebstahl als auch Attentatsversuchen sicherer Rolladenpanzer ergibt. Gleichzeitig müssen jedoch auch die mit Belüftungsöffnungen versehenen Verbindungsstäbe wegen der Schwächung durch die­se Öffnungen aus Aluminium hergestellt sein, um nicht unter dem Gewicht der Rolladenstäbe zu brechen, was nicht nur den Rolladen verteuert, sondern eine übermäßig starke Abdunke­lung auch bei in die Lüftungsstellung angehobenem Rolladen­panzer mit sich bringt.Yet another known roller shutter of the type mentioned Gestalt uses box-shaped roller shutter slats made of extruded aluminum, which results in a relatively heavy and stiff roller shutter curtain that is both secure against theft and attempted assassinations. At the same time, however, because of the weakening through these openings, the connecting rods provided with ventilation openings must also be made of aluminum so that they do not break under the weight of the roller shutter rods, which not only increases the cost of the roller shutters, but also causes excessive darkening even when the roller shutter curtain is raised in the ventilation position brings itself.

Aufgabe der Erfindung ist es deshalb einen Rolladenpanzer der eingangs genannten Art dahingehend auszubilden, daß bei in die Lüftungsstellung angehobenem Panzer neben einer ausreichenden Belüftung eine zu starke Abdunkelung des da­hinterliegenden Raumes vermieden ist.The object of the invention is therefore to design a roller shutter curtain of the type mentioned in such a way that, in addition to adequate ventilation, excessive darkening of the space behind it is avoided when the curtain is raised into the ventilation position.

Erfindungsgemäß wird diese Aufgabe dadurch gelöst, daß die Verbindungsstäbe aus lichtdurchlässigem Kunststoff bestehen und die Belüftungsöffnungen in den inneren Seitenwänden der kastenförmigen Rolladenstäbe so angeordnet sind, daß sie mit den oberen und/oder unteren Schlitzen der Rolladenstäbe kommunizieren.According to the invention this object is achieved in that the connecting rods are made of translucent plastic and the ventilation openings in the inner side walls of the box-shaped roller shutter slats are arranged so that they communicate with the upper and / or lower slots of the roller shutter slats.

Durch die erfindungsgemäße Verlagerung der Belüftungsöff­nungen in die kastenförmigen Rolladenstäbe entfällt eine Schwächung der Verbindungsstäbe, und diese lassen sich trotz des von den metallenen Rolladenstäben bestimmten Pan­zergewichts ohne Bruchgefahr aus einem lichtdurchlässigen Kunststoff herstellen, der den gewünschten Lichtdurchtritt sicherstellt. Dennoch ist eine ausreichende Belüftung ge­währleistet, da die in den inneren Profilseitenwänden der kastenförmigen Rolladenstäbe angeordneten Belüftungsöffnun­gen über die oberen und/oder unteren Längsschlitze an den Rolladenstäben, deren Breite größer als die Dicke der Ver­ bindungsstäbe ist, zur Atmosphäre hin offen sind. Die Be­lüftungsöffnungen können sogar beliebig groß ausgebildet werden, weil sie zum einen die Festigkeit der metallenen Rolladenstäbe praktisch nicht beeinträchtigen und zum ande­ren die Gefahr des Eindringens von Insekten und Staub über den langen Belüftungsweg erheblich verringert ist.Due to the inventive displacement of the ventilation openings in the box-shaped roller shutter bars, there is no weakening of the connecting bars, and despite the armor weight determined by the metal roller shutter bars, they can be produced from a translucent plastic without risk of breakage, which ensures the desired passage of light. Adequate ventilation is nevertheless ensured since the ventilation openings arranged in the inner profile side walls of the box-shaped roller shutter slats via the upper and / or lower longitudinal slots on the roller shutter slats, the width of which is greater than the thickness of the ver tie rods is open to the atmosphere. The ventilation openings can even be of any size because, on the one hand, they practically do not adversely affect the strength of the metal roller shutter slats and, on the other hand, the risk of insects and dust penetrating over the long ventilation path is considerably reduced.

Zweckmäßig bestehen die Verbindungsstäbe aus einem Polykar­bonat, das farblos oder auch eingefärbt sein kann.The connecting rods advantageously consist of a polycarbonate, which can be colorless or colored.

Um bei voller Durchsichtigkeit des die Verbindungsstäbe bildenden Materials eine ungedämpfte Weiterleitung der hin­durchdringenden Sonnenstrahlen in den Innenraum zu vermei­den, sieht ein Merkmal zur vorteilhaften Ausgestaltung der Erfindung vor, daß die Verbindungsstäbe zwischen den haken­förmigen Profilenden auf wenigstens einer Seite mit einer lichtbrechenden Oberflächenstruktur versehen sind. Diese ist zweckmäßig durch ein stumpfwinkliges Zickzackprofil der strukturierten Oberfläche gebildet.In order to avoid an undamped transmission of the penetrating sun rays into the interior with full transparency of the material forming the connecting rods, a feature of the advantageous embodiment of the invention provides that the connecting rods between the hook-shaped profile ends are provided on at least one side with a refractive surface structure. This is expediently formed by an obtuse-angled zigzag profile of the structured surface.

Nach einem anderen Merkmal zur vorteilhaften Ausgestaltung der Erfindung ist wenigstens die äußere Seitenwand eines jeden kastenförmigen Rolladenstabes an einem Profilende mit einer überstehenden schmalen Profilzunge versehen, die bei geschlossenem Rolladen in eine entsprechende Profilaus­nehmung am anderen Profilende der Seitenwand des nächsten Rolladenstabes überlappend eingreift.According to another feature of the advantageous embodiment of the invention, at least the outer side wall of each box-shaped roller shutter bar is provided at one profile end with a protruding narrow profile tongue which, when the roller shutter is closed, overlaps in a corresponding profile recess on the other profile end of the side wall of the next roller shutter bar.

Im übrigen kann das Kastenprofil der Rolladenstäbe symme­trisch oder unsymmetrisch ausgebildet sein, wobei im erste­ren Fall das Kastenprofil durch eine die Seitenwände verbin­dende Querwand in zwei gleichgroße, über je einen Längs­schlitz nach oben oder unten offene Kammern unterteilt ist, in welche beim vollständigen Schließen des Rolladens die Verbindungsstäbe jeweils zur Hälfte einfahren. Dies ermöglicht eine weitere Ausgestaltung dahingehend, daß die innere Seitenwand jedes Rolladenstabes mit zwei Reihen von Belüftungsöffnungen versehen ist, die zu je einer der bei­den Kammern führen.Otherwise, the box profile of the roller shutter slats can be symmetrical or asymmetrical, in the former case the box profile is divided by a transverse wall connecting the side walls into two equal-sized chambers, each of which has a longitudinal slot that is open upwards or downwards, into which, when the roller shutter is completely closed, the Retract the connecting rods halfway. This allows a further embodiment in that the inner side wall of each roller shutter bar is provided with two rows of ventilation openings, each leading to one of the two chambers.

Im Falle der asymmetrischen Ausbildung des Kastenprofils der Rolladenstäbe ist dieses durch eine die Seitenwände verbindende Querwand in eine lange Kammer zur verschiebli­chen und verschwenkbaren Aufnahme des daran ansetzenden Verbindungsstabes und eine kurze Kammer zur bloßen schwenk­baren Aufnahme des Hakens am dortigen Verbindungsstab unter­teilt. In diesem Falle wird dann zweckmäßig die innere Sei­tenwand jedes kastenförmigen Rolladenstabes mit nur einer Reihe von Belüftungsöffnungen versehen, die zu der langen Kammer führen.In the case of the asymmetrical design of the box profile of the roller shutter slats, this is divided by a transverse wall connecting the side walls into a long chamber for the displaceable and pivotable reception of the connecting rod attached thereto and a short chamber for the mere pivotable reception of the hook on the connecting rod there. In this case, the inner side wall of each box-shaped roller shutter bar is then expediently provided with only one row of ventilation openings which lead to the long chamber.

Die Erfindung wird nachstehend anhand zweier Ausführungsbei­spiele in Verbindung mit der Zeichnung näher erläutert. Darin zeigen:

  • Fig. 1 in schematischer Darstellung die Stirn­ansicht einer ersten Ausführungsform des erfindungsgemäßen Rolladenpanzers in voll herabgelassenem oder geschlos­senem Zustand,

The invention is explained in more detail below using two exemplary embodiments in conjunction with the drawing. In it show:
  • 1 is a schematic representation of the front view of a first embodiment of the roller shutter curtain according to the invention in the fully lowered or closed state,
  • 2 shows the same end view as in FIG. 1 in the raised ventilation position of the tank,

Der in den Figuren 1 bis 4 dargestellte Rolladenpanzer 10 besteht aus einem unteren Teil 12 mit abwechselnd aufein­anderfolgenden kastenförmigen Rolladenstäben 12 und Ver­bindungsstäben 14 sowie einem oberen Teil mit herkömmlichen Profilstäben 16 und ist am unteren Ende durch einen hohlen Endstab 18 von wesentlich größerem Querschnitt als die vor­erwähnten Stäbe abgeschlossen. Das (nicht gezeigte) obere Ende des Panzers ist in herkömmlicher Weise an einer Pan­zerwelle innerhalb eines Rolladenkastens festgelegt und kann elektromotorisch oder von Hand auf diese zum Anheben des Panzers in die in Fig. 2 gezeigte Lüftungsstellung oder zum völligen Hochziehen des Panzers aufgewickelt werden. Im vollständig abgewickelten Zustand nehmen die Stäbe 12, 14, 16 des Rolladenpanzers die in Fig. 1 gezeigte Stellung ein, in welcher der Endstab 18, je nach Anwendungsfall, durch eine Fensterbank oder eine Türschwelle abgefangen ist, so daß sich sämtliche darüber befindliche Stäbe 12, 14, 16 ineinander schieben und die Verbindungsstäbe 14 voll­ständig in den kastenförmigen Rolladenstäben 12 aufgenommen sind.The roller shutter curtain 10 shown in Figures 1 to 4 consists of a lower part 12 with alternating successive box-shaped roller shutter bars 12 and connecting bars 14 and an upper part with conventional profile bars 16 and is at the lower end by a hollow end bar 18 of substantially larger cross section than the aforementioned Rods completed. The upper end (not shown) of the tank is fixed in a conventional manner to an armored shaft within a roller shutter box and can be wound onto it by an electric motor or by hand to lift the tank into the ventilation position shown in FIG. 2 or to pull the tank up completely. In the completely unwound state, the bars 12, 14, 16 of the roller shutter curtain assume the position shown in FIG. 1, in which, depending on the application, the end bar 18 is intercepted by a window sill or a door sill, so that all of the bars 12 located thereover , 14, 16 slide into one another and the connecting rods 14 are completely accommodated in the box-shaped roller shutter rods 12.

Die kastenförmigen Rolladenstäbe 12 bestehen aus extrudier­tem Aluminium mit einem in der Hauptsache H-förmigen Profil 20 und weisen dadurch eine äußere Seitenwand 22 und eine dazu parallele innere Seitenwand 24 auf, die in der Profil­mitte durch eine Querwand 26 miteinander verbunden sind.The box-shaped roller shutter slats 12 consist of extruded aluminum with a mainly H-shaped profile 20 and thereby have an outer side wall 22 and an inner side wall 24 parallel thereto, which are connected to one another in the middle of the profile by a transverse wall 26.

Hierdurch wird das Innere eines jeden kastenförmigen Rolla­denstabes 12 in eine obere Kammer 28 und eine untere Kammer 30 gleicher Größe unterteilt, die zu den Profilenden hin über Längsschlitze 32, 34 geöffnet sind, welche von der äußeren Seitenwand 22 und jeweils einer Abkantung 36 bzw. 38 der inneren Seitenwand 24 begrenzt sind. Ferner ist an der äußeren Seitenwand 22 am unteren Profilende eine im Vergleich zur dortigen Wandstärke etwa halb so breite Pro­filzunge 40 angeformt, die in der vollständig herabgelasse­nen Stellung des Rolladenpanzers nach Fig. 1 in eine ent­sprechend breite Profilausnehmung 42 am anderen Profilende der äußeren Seitenwand 22 des nächsten Rolladenstabs 18 überlappend eingreift.As a result, the inside of each box-shaped roller shutter bar 12 is divided into an upper chamber 28 and a lower chamber 30 of the same size, which are opened towards the profile ends via longitudinal slots 32, 34, which are formed by the outer side wall 22 and in each case by a fold 36 and 38 the inner side wall 24 are limited. Furthermore, a profile tongue 40 is formed on the outer side wall 22 at the lower end of the profile, which is about half as wide as the wall thickness there, which in the fully lowered position of the roller shutter curtain according to FIG. 1 into a correspondingly wide profile recess 42 at the other profile end of the outer side wall 22 of the next roller shutter bar 18 engages overlapping.

Die Verbindungsstäbe 14 bestehen aus einem lichtdurchlässi­gen Kunststoff, wie insbesondere einem Polykarbonat, das farblos oder eingefärbt sein kann, und weisen einen langge­streckten symmetrischen C-Querschnitt mit einem geraden mittleren Wandungsteil 44 und daran anschließenden haken­förmigen Enden 46 auf, die durch die Schlitze 32, 34 in die Hohlkammern 28, 30 der anschließenden Rolladenstäbe 12 eingreifen und sich hinter den Abkantungen 36 bzw. 38 der inneren Seitenwand 24 verhaken, wodurch eine Verschwenk­barkeit der Verbindungsstäbe 14 gegenüber den kastenförmi­gen Rolladenstäben 12 erhalten wird, die das Aufwickeln des Rolladenpanzers ermöglicht. Durch entsprechend lange Gestaltung der Hohlkammern 28, 30 und des geraden Wandungs­teils 44 der Verbindungsstäbe 14 lassen sich diese außer­dem je zur Hälfte in die Hohlkammern 28, 30 beim Aufsetzen der Endleiste 18 auf das Fensterbrett bzw. die Bodenschwel­le der zu verschließenden Türöffnung hineinschieben, um die in Fig. 1 gezeigte vollgeschlossene Stellung des Rolla­denpanzers zu erhalten.The connecting rods 14 are made of a translucent plastic, such as in particular a polycarbonate, which can be colorless or colored, and have an elongated, symmetrical C cross section with a straight central wall part 44 and adjoining hook-shaped ends 46, which pass through the slots 32, 34 engage in the hollow chambers 28, 30 of the subsequent roller shutter slats 12 and hook behind the folds 36 and 38 of the inner side wall 24, respectively, whereby the connecting bars 14 can be pivoted relative to the box-shaped roller shutter slats 12, which enables the roller shutter curtain to be wound up. By suitably long design of the hollow chambers 28, 30 and the straight wall part 44 of the connecting rods 14, these can also each be inserted in half into the hollow chambers 28, 30 when the end strip 18 is placed on the window sill or the threshold of the door opening to be closed, in order to To get the fully closed position of the shutter curtain shown in Fig. 1.

Die Längsschlitze 32, 34 in den kastenförmigen Rolladenlei­sten 12 sind breiter ausgebildet als die Dicke der Verbin­ dungsstäbe 14, so daß die Hohlkammern 28, 30 ständig mit der umgebenden Atmosphäre vor dem Rolladenpanzer in Verbin­dung stehen. Weiterhin befinden sich in der inneren Seiten­wand 24 zwei Reihen von Belüftungsöffnungen, die jeweils zu einer der beiden Hohlkammern 28, 30 in den kastenförmi­gen Rolladenleisten 12 führen. Dadurch wird in der Belüf­tungsstellung des Rolladenpanzers, in der sich die Profil­zungen 40 außer Eingriff mit den Profilaussparungen 42 der Rolladenleisten 12 befinden, ein durchgehender Belüftungs­weg von der Außenseite des Rolladenpanzers zu dessen Innen­seite erhalten, der durch die eine oder andere Hohlkammer 28 bzw. 30 verläuft und so lang ist, daß ein Durchtritt von Staub oder Insekten weitgehend vermieden wird. Gleichzeitig wird durch die Verlagerung der Belüftungsöffnungen in die kastenförmigen Rolladenprofile erreicht, daß der Panzer nicht nur im vollständig herabgelassenen Zustand, sondern auch in der angehobenen Stellung, in der das Tageslicht durch die lichtdurchlässigen Verbindungsstäbe hindurchtre­ten kann, dennoch eine wirksame Schalldämmung hervorruft.The longitudinal slots 32, 34 in the box-shaped roller shutter slats 12 are wider than the thickness of the connector extension bars 14 so that the hollow chambers 28, 30 are in constant communication with the surrounding atmosphere in front of the roller shutter curtain. Furthermore, there are two rows of ventilation openings in the inner side wall 24, each of which leads to one of the two hollow chambers 28, 30 in the box-shaped roller shutter slats 12. As a result, in the ventilation position of the roller shutter curtain, in which the profile tongues 40 are disengaged from the profile recesses 42 of the roller shutter slats 12, a continuous ventilation path is obtained from the outside of the roller shutter curtain to the inside thereof, which runs through one or the other hollow chamber 28 or 30 and is so long that the passage of dust or insects is largely avoided. At the same time, the displacement of the ventilation openings in the box-shaped roller shutter profiles means that the armor does not only provide effective sound insulation not only in the fully lowered state but also in the raised position in which daylight can pass through the translucent connecting rods.

Die in den Figuren 5 und 6 gezeigte abgeänderte Ausführungs­form, für deren Erläuterung dieselben Bezugszeichen wie bei den Figuren 1 bis 4 für die entsprechenden Teile ver­wendet sind, unterscheidet sich von der zuvor beschriebenen Ausführungsform nur dadurch, daß die dort mit 26′ bezeichne­te Querwand der kastenförmigen Rolladenleisten 12 asymme­trisch verschoben ist, so daß die obere Kammer 28′ wesent­lich länger als beim zuvor beschriebenen Ausführungsbei­spiel und die untere Kammer 30′ entsprechend kürzer ist. Die Profillänge der Rolladenleisten 12 ebenso wie die Pro­fillänge der Verbindungsstäbe 14 sind hingegen diegleichen wie beim Ausführungsbeispiel nach den Figuren 1 bis 4, so daß auch bei der Ausführungsform nach den Figuren 5 und 6 die kastenförmigen Rolladenleisten 12, diesmal unter Ver­schiebung der Verbindungsstäbe 14 nur in die obere Kammer 28′ vollständig in die Eingriffsstellung der Profilzungen 40 mit den Profilausnehmungen 42 gemäß Fig. 5 verschoben werden können. Die untere Kammer 30 ist demgegenüber so kurz gehalten, daß das eingreifende obere hakenförmige Ende 46 des nach unten anschließenden Verbindungsstabes 14 gegen­über dem kastenförmigen Rolladenstab 12 nur verschwenkt werden kann.The modified embodiment shown in Figures 5 and 6, for the explanation of which the same reference numerals are used as in Figures 1 to 4 for the corresponding parts, differs from the previously described embodiment only in that there designated 26 'transverse wall of the box-shaped Roller shutter slats 12 is shifted asymmetrically, so that the upper chamber 28 'is significantly longer than in the previously described embodiment and the lower chamber 30' is correspondingly shorter. The profile length of the roller shutter slats 12 as well as the profile length of the connecting rods 14, however, are the same as in the embodiment according to Figures 1 to 4, so that in the embodiment according to Figures 5 and 6, the box-shaped roller shutter slats 12, this time with displacement of the connecting rods 14 only in the upper chamber 28 'can be moved completely into the engagement position of the profile tongues 40 with the profile recesses 42 according to FIG. 5. In contrast, the lower chamber 30 is kept so short that the engaging upper hook-shaped end 46 of the connecting rod 14 which adjoins the bottom can only be pivoted relative to the box-shaped roller shutter rod 12.

Bei der Ausführung der kastenförmigen Rolladenstäbe 12′ nach Fig. 5 und 6 enthalten die dortigen inneren Seiten­wände 24′ nur eine Reihe von Belüftungsöffnungen 48, die zu der oberen Kammer 28′ führen und über diese und die obe­ren Längsschlitze 32′ sich einen Belüftungsweg zur Außen­seite des Rolladenpanzers bilden. Anstelle der gezeigten einen Reihe von Belüftungsöffnungen können selbstverständ­lich auch zwei oder mehrere derartige Reihen vorgesehen seien, die jedoch sämtliche zur oberen Kammer 28′ führen.5 and 6, the inner side walls 24 'therein contain only one row of ventilation openings 48 which lead to the upper chamber 28' and via this and the upper longitudinal slots 32 'there is a ventilation path to the outside form the roller shutter curtain. Instead of the one row of ventilation openings shown, two or more such rows can of course also be provided, but all of them lead to the upper chamber 28 '.

Wie bereits erwähnt, bestehen die Verbindungsstäbe 14 aus einem lichtdurchlässigen Kunststoff, der voll durchsichtig sein kann. Da in diesem Fall die Sonnenstrahlen zumindest bei tiefstehender Sonne ungebrochen in den Gebäudeinnenraum eintreten würden, ist es zweckmäßig, für eine Lichtbrechung zu sorgen. Diese wird, wie in Fig. 2 dargestellt, zweck­mäßig dadurch erhalten, daß entweder die Außenseite des geraden Wandungsteils 44 der hakenförmigen Verbindungsstäbe 14 oder deren Innenseite oder auch beide Seiten mit einer lichtbrechenden Oberflächenstruktur vorzugsweise in Gestalt eines stumpfwinkligen Zickzackprofils 50 versehen sind.As already mentioned, the connecting rods 14 consist of a translucent plastic which can be completely transparent. In this case, since the sun's rays would enter the interior of the building uninterrupted, at least when the sun was low, it is advisable to ensure that the light refracts. As shown in FIG. 2, this is expediently obtained by providing either the outside of the straight wall part 44 of the hook-shaped connecting rods 14 or the inside thereof or both sides with a refractive surface structure, preferably in the form of an obtuse-angled zigzag profile 50.
