Description

Die Erfindung betrifft einen wärmedämmenden Vorhang aus mindestens zwei mit Abstand zueinander angeordneten in eine Vorhangöffnung einführbaren Vorhangbahnen und mit seitlichen Führungsschienen zur Aufnahme der Seitenränder der abgewickelten Vorhangbahnen, die gemeinsam von einer Walze über Führungselemente abwickelbar sind und die an ihrem der Walze abgewandten Ende Beschwerungsgewichte aufweisen.The invention relates to a heat-insulating curtain consisting of at least two spaced-apart curtain webs that can be inserted into a curtain opening and with lateral guide rails for receiving the side edges of the unwound curtain webs, which can be unwound together from a roller via guide elements and have weight weights at their end facing away from the roller.

Die Wärmeverluste in Gebäuden werden zu einem sehr großen Anteil von den Fenstern verursacht. Während die Außenwände eine gute Wärmeisolierung bilden, sind die Wärmeverluste an Fenstern - selbst bei Isolierverglasung bzw. Mehrfachverglasung - um ein Vielfaches höher. Die grundsätzliche Zielrichtung der Gebäudetechnik ist daher, Fensterflächen zu schaffen, die tagsüber viel Licht hindurchlassen und je nach Außenwitterung die Wärmestrahlung abschirmen oder auffangen, und umgekehrt nachts, z.B. im Winter, eine Wärmedämmung bewirken, Diese vielfältigen Aufgaben können nicht von den Fensterflächen allein erfüllt werden. Vielmehr kommen hierzu spezielle Vorhangtechniken zum Einsatz, die für Fensterflächen oder für ganze Fassaden geeignet sind und die ein Höchstmaß an Anpassung an die klimatischen Bedingungen ermöglichen.To a large extent, the heat losses in buildings are caused by the windows. While the outer walls provide good thermal insulation, the heat losses at windows - even with double glazing or multiple glazing - are many times higher. The basic aim of building technology is therefore to create window areas that let in a lot of light during the day and, depending on the outside weather, shield or absorb heat radiation, and vice versa at night, e.g. in winter, to provide thermal insulation, these diverse tasks cannot be performed by the window surfaces alone. Rather, special curtain techniques are used for this, which are suitable for window surfaces or for entire facades and which allow a maximum degree of adaptation to the climatic conditions.

Bei Vorhängen, bei denen mehrere Vorhangbahnen auf eine Walze aufgewickelt sind, ergibt sich das Problem, daß die Länge der einzelnen Vorhangbahnen immer nur für eine Stellung des Vorhangs angepaßt werden kann.With curtains in which several curtain sheets are wound on a roller, the problem arises that the length of the individual curtain sheets can only be adapted for one position of the curtain.

Bei einem bekannter Rollvorhang (DE-PS 29 34 674) aus einer dicken, mit Gewebe oder Folie kaschierten Weichschaumbahn, und einer Dekorvorhangbahn, die gemeinsam mit der Weichschaumbahn auf einer Walze aufgewickelt ist, ist die Länge der Bahnen lediglich für den ausgerollten Zustand exakt angepaßt. Beim Aufrollen wird dann die in Relation zur Walzenachse weiter außen liegende Vorhangbahn schneller aufgewickelt, da für sie der effektive Walzendurchmesser immer größer ist als für weiter innen liegende Vorhangbahnen. Dadurch kann der gesamte Vorhang nur so weit aufgerollt werden, bis die am meisten aufgewickelte Vorhangbahn - in diesem Fall die Dekorvorhangbahn - aus den oberen Führungselementen herauszugleiten droht oder gegen einen Anschlag stößt. Die Weichschaumbahn selbst ist dann noch nicht vollständig aufgerollt und hat sich darüber hinaus wegen ihrer Dicke aus den zuvorgenannten Gründen in vertikaler Richtung verzogen, so daß ihre untere breite Kante nicht gerade abschließt.In a known rolling curtain (DE-PS 29 34 674) made of a thick, foam-laminated soft foam sheet, and a decorative curtain sheet, which is wound together with the soft foam sheet on a roller, the length of the sheets is only adapted exactly for the rolled-out state . When rolling up, the curtain sheet lying further outside in relation to the roll axis is then wound up faster, since the effective roll diameter for it is always larger than for curtain sheets lying further inside. As a result, the entire curtain can only be rolled up until the most wound curtain sheet - in this case the decorative curtain sheet - threatens to slide out of the upper guide elements or hits a stop. The soft foam sheet itself is then not yet completely rolled up and, because of its thickness, has also warped in the vertical direction for the reasons mentioned above, so that its lower wide edge does not exactly close off.

Der Erfindung liegt die Aufgabe zugrunde, einen Vorhang der eingangs genannten Art zu schaffen, bei dem im Bereich der Vorhangöffnung in beiden Endstellungen des Vorhangs hinsichtlich der optischen Wirkung ein sauberer Abschluß des Vorhangs ermöglicht ist.The invention has for its object to provide a curtain of the type mentioned, in which in the region of the curtain opening in both end positions of the curtain with respect to the optical effect a clean conclusion of the curtain is made possible.

Zur Lösung dieser Aufgabe ist erfindungsgemäß vorgesehen, daß am oberen und/oder unteren Ende der Vorhangöffnung ein Schlitzkasten angeordnet ist, der Schlitze für den Durchgang der einzelnen Vorhangbahnen und deren Beschwerungsgewichte aufweist und dessen Erstreckung in Längsrichtung der Vorhangbahnen so groß ist, daß er die nicht miteinander verbundenen Enden der unterschiedlich weit abgewickelten Vorhangbahnen gleichzeitig aufnimmt.To achieve this object, it is provided according to the invention that a slot box is arranged at the upper and / or lower end of the curtain opening, the slots for the passage of the individual curtain sheets and their weight weights and its extension in the longitudinal direction of the curtain sheets is so large that it does not interconnected ends of the differently developed curtain sheets at the same time.

Der Schlitzkasten ermöglicht es, in vorteilhafter Weise den unvermeidlichen ungleichen Abschluß der Endkanten einzelner gemeinsam aufgewickelter Vorhangbahnen in einer der Extremstellungen des Vorhangs zu verblenden, so daß der ungleiche Abschluß nicht sichtbar ist.The slit box advantageously enables the unavoidable uneven termination of the end edges of individual curtain webs that are co-wound in one of the extreme positions of the curtain to be blended so that the uneven termination is not visible.

Bei ungleichem Abschluß der Enden der Vorhangbahn im aufgewickelten Zustand des Vorhangs ist vorgesehen, daß der Schlitzkasten am oberen Ende der Vorhangöffnung angeordnet ist und derart bemessen ist, daß das Ende der am wenigsten aufgewickelten Vorhangbahn sich vollständig im Schlitzkasten befindet, wenn das Ende der am meisten aufgewickelten Vorhangbahn gerade in der oberen Endstellung ist.If the ends of the curtain sheet are uneven when the curtain is wound up, it is provided that the slit box is arranged at the upper end of the curtain opening and is dimensioned such that the end of the least wound curtain sheet is completely in the slit box when the end of the most wound curtain sheet is just in the upper end position.

Ein solcher Schlitzkasten ermöglicht einerseits die Aufnahme der Enden der Vorhangbahnen, während diese noch von den Führungswalzen geführt sind, und läßt andererseits die Vorhangbahn zum Aufwickeln auf die Walze hindurch.Such a slotted box enables the ends of the curtain sheets to be received while they are still guided by the guide rollers, and also allows the curtain sheets to be wound onto the roller.

Bei ungleichem Abschluß der Enden der Vorhangbahnen im abgewickelten Zustand ist vorgesehen, daß der Schlitzkasten am unteren Ende der Vorhangöffnung angeordnet ist und derart bemessen ist, daß sich das Ende der am wenigsten abgewickelten Vorhangbahn im Schlitzkasten befindet, wenn das Ende der am meisten abgewickelten Vorhangbahn in seiner unteren Endstellung ist. Auf diese Weise wird verhindert, daß empfindliche Vorhangbahnen verkratzt oder geknickt werden.If the ends of the curtain sheets are unevenly finished in the unwound state, it is provided that the slot box is arranged at the lower end of the curtain opening and is dimensioned such that the end of the least unwound curtain sheet is in the slot box when the end of the most unwound curtain sheet is in is its lower end position. This prevents sensitive curtain sheets from being scratched or kinked.

Die Schlitzkästen können parallel zu den ausgestreckten Vorhangbahnen verlaufende Trennwände aufweisen, die gemeinsam mit dem Schlitzkasten für jede der einzelnen Vorhangbahnen jeweils voneinander getrennte Schlitzkastenkammern mit jeweils einem Schlitz bilden. Dadurch wird in vorteilhafter Weise eine konvektive Trennung in der Art einer Labyrinth-Dichtung zwischen den einzelnen Vorhangsbahnen in den Schlitzkästen erzielt.The slot boxes can have dividing walls running parallel to the extended curtain sheets, which together with the slot box form separate slot box chambers with a slot for each of the individual curtain sheets. As a result, a convective separation in the manner of a labyrinth seal between the individual curtain sheets in the slot boxes is advantageously achieved.

Ein bevorzugtes Ausführungsbeispiel ist dadurch gekennzeichnet, daß der Schlitzkasten abgedichtet ist und daß mindestens die jeweils äußeren Schlitze des Schlitzkastens über die gesamte Schlitzbreite und die äußeren Führungsschienen über die gesamte Schienenlänge verlaufende Dichtungselemente aufweisen, die sich beidseitig an die jeweiligen Vorhangbahnen anlegen. Durch die Abdichtung des Schlitzkastens bilden die einzelnenA preferred exemplary embodiment is characterized in that the slot box is sealed and that at least the respective outer slots of the slot box have sealing elements which extend over the entire slot width and the outer guide rails extend over the entire length of the rail and which abut the respective curtain tracks on both sides. By sealing the slot box form the individual

Vorhangbahnen gemeinsam mit dem Schlitzkasten und den Führungsschienen einen luftdicht geschlossenen Raum, der aufgrund des verhinderten Luftaustausches besonders isolierend wirkt. Dabei können alle Schlitze und Führungsschienen Dichtungselemente aufweisen, so daß mehrere getrennte Luftkammern gebildet werden, oder nur die jeweils äußeren Schlitze und Führungsschienen. In diesem Fall wird eine gemeinsame Luftkammer durch die Vorhangbahnen unterteilt. Wichtig ist, daß diese Luftkammer nach außen durch die Dichtungselemente in den äußeren Schlitzen und Führungsschienen abgeschlossen ist.Curtain tracks together with the slotted box and the guide rails create an airtight, closed space that has a particularly insulating effect due to the prevented air exchange. All slots and guide rails can have sealing elements, so that several separate air chambers are formed, or only the respective outer slots and guide rails. In this case, a common air chamber is divided by the curtain sheets. It is important that this air chamber is closed to the outside by the sealing elements in the outer slots and guide rails.

Bei einem vorteilhaften Ausführungsbeispiel ist vorgesehen, daß die Schlitze auf der gesamten Schlitzbreite Reinigungs- und/oder Antistatikelemente aufweisen, die sich beidseitig an die jeweiligen Vorhangbahnen anlegen. Auf diese Weise wird eine Verschmutzung der Vorhangbahnen wirkungsvoll verhindert.In an advantageous embodiment, it is provided that the slots have cleaning and / or antistatic elements over the entire slot width, which abut the respective curtain sheets on both sides. In this way, contamination of the curtain sheets is effectively prevented.

Eine vorteilhafte Weiterbildung der Erfindung sieht vor, daß die Führungsschienen Hohlprofile sind und daß die Beschwerungsgewichte an den in den Führungsschienen hineinragenden Seitenkanten der Vorhangbahnen in der Nähe der unteren Enden befestigt sind. Auf diese einfache Weise werden die Beschwerungsgewichte, die für einen einwandfreien Fall des Vorhangs notwendig sind, so verdeckt, daß sie für den Betrachter nicht sichtbar sind.An advantageous development of the invention provides that the guide rails are hollow profiles and that the weights are attached to the side edges of the curtain sheets projecting into the guide rails in the vicinity of the lower ends. In this simple way, the weighting weights that are necessary for the curtain to fall properly are concealed so that they are not visible to the viewer.

Vorzugsweise ist dabei vorgesehen, daß die Innenräume der Führungsschienen mit dem Innenraum des Schlitzkastens verbunden sind. Dadurch werden die Vorhangbahnen auch in den Schlitzkästen,insbesondere in dem am oberen Ende der Vorhangöffnung angeordneten Schlitzkasten sicher geführt, ohne daß Einfädelungsprobleme beim Übergang zwischen den Führungsschienen und dem Schlitzkasten entstehen.It is preferably provided that the interior of the guide rails are connected to the interior of the slot box. As a result, the curtain tracks are also guided securely in the slotted boxes, in particular in the slotted box arranged at the upper end of the curtain opening, without threading problems arising during the transition between the guide rails and the slotted box.

Zusätzlich können die Beschwerungsgewichte durch eine Versteifungsschiene miteinander verbunden sein. Dadurch vorteilt sich die Zuglast an den einzelnen Vorhangbahnen gleichmäßig über die gesamte Breite der Vorhangbahn und erleichtert den Durchtritt der Vorhangbahnen durch die Dichtlippen der Schlitze in den Schlitzkästen.In addition, the weighting weights can be connected to each other by a stiffening rail. As a result, the tensile load on the individual curtain sheets spreads evenly over the entire width of the curtain sheet and facilitates the passage of the curtain sheets through the sealing lips of the slots in the slot boxes.

Die Walze 4 ist am oberen Ende der Vorhangöffnung 3 angeordnet und mit ihren Enden in einer Haltevorrichtung 5 gelagert, die zugleich einen Kasten zur Aufnahme er Walze 4 bildet. Dieser Kasten wird an der Wand bzw. der Decke des Raumes befestigt.In Figs. 1, 4, 5 and 6 each show a window 1 which is delimited by an outer wall 2 of a building. Inside the building, behind the window in the curtain opening 3, there is the heat-insulating curtain, which consists of several parallel, film-like and transparent curtain sheets 30, 31, 32, 33. These webs can be wound together on a roller 4, one on top of the other. The roller 4 is arranged at the upper end of the curtain opening 3 and supported with its ends in a holding device 5, which at the same time forms a box for receiving the roller 4. This box is attached to the wall or ceiling of the room.

Die als Kasten ausgebildete Haltevorrichtung 5 weist einen Schlitzboden 14 mit Schlitzen für den Durchtritt der Bahnen 30 bis 33 auf. Oberhalb dieser Schlitze befinden sich die Führungswalzen 6, bei denen es sich um drehbar gelagerte Zylinder handelt, von denen jeder zum Umlenken einer der Vorhangbahnen 30 bis 33 dient. Die Achsen dieser Führungswalzen 6 verlaufen parallel zur Achse der Walze 4. Sie haben die gleiche Länge wie die Walze 4 und sind seitlich neben dieser, jedoch geringfügig nach unten versetzt angeordnet.The holding device 5 designed as a box has a slotted bottom 14 with slits for the passage of the webs 30 to 33. Above these slots are the guide rollers 6, which are rotatably mounted cylinders, each of which serves to deflect one of the curtain tracks 30 to 33. The axes of these guide rollers 6 run parallel to the axis of the roller 4. They have the same length as the roller 4 and are arranged laterally next to it, but slightly offset downwards.

Die seitlichen Bahnkanten sind im Bereich der Vorhang-Öffnung 3 im gestreckten Zustand der Vorhangbahnen 30 bis 33 in vertikalen Führungsschienen 9 geführt, welche die von den Vorhangbahnen im abgewickelten Zustand gebildeten Luftkammern an den stirnseitigen Kanten abschließen und die Kantendichtungen 10 aufweisen, die sich von entgegengesetzten Seiten gegen die Vorhangbahnen anlehnen. Die Luftkammern werden folglich von den Vorhangbahnen und den Kantendichtungen begrenzt und können am oberen und unteren Ende der Vorhangöffnung zusätzlich abgedichtet sein. Durch den fehlenden oder geringen Luftaustausch wirken die Luftkammern besondern isolierend. Die Führungsschienen 9 erstrecken sich in Fig. 1 geradlinig von der die obere Begrenzung der Vorhangöffnung 3 bildenden Haltevorrichtung 5 bis zu einem Schlitzkasten 11, der die untere Begrenzung der Vorhangöffnung bildet. Die Führungsschienen 9 sind - im Querschnitt gesehen - Hohlprofile, die einen durch Dichtungselemente 10 begrenzten längslaufenden Schlitz aufweisen. Durch diesen Schlitz ragt das seitliche Ende der betreffenden Bahn in das Innere des Hohlprofiles hinein, so daß die Bahnkanten im Inneren der Führungsschienen 9 angeordnet sind. Die seitliche Bahnführung erfolgt zwischen den Dichtungselementen 10. Die Dichtungselemente 10 bestehen beispielsweise aus Bürsten oder flexiblen Dichtlippen, die den Wänden derThe lateral web edges are guided in the region of the curtain opening 3 in the stretched state of the curtain webs 30 to 33 in vertical guide rails 9, which close off the air chambers formed by the curtain webs in the unwound state on the front edges and have the edge seals 10 which are opposite Lean the sides against the curtain sheets. The air chambers are consequently delimited by the curtain sheets and the edge seals and can additionally be sealed at the upper and lower ends of the curtain opening. Due to the lack or little air exchange, the air chambers have a particularly insulating effect. The guide rails 9 extend in a straight line in FIG. 1 from the holding device 5 which forms the upper boundary of the curtain opening 3 to a slot box 11 which forms the lower boundary of the curtain opening. The guide rails 9 are - seen in cross section - hollow profiles which have a longitudinal slot delimited by sealing elements 10. Through this slot, the lateral end of the web in question protrudes into the interior of the hollow profile, so that the web edges are arranged in the interior of the guide rails 9. The lateral web guidance takes place between the sealing elements 10. The sealing elements 10 consist, for example, of brushes or flexible sealing lips that cover the walls of the

Führungsschienen 9 angeformt sind. Die vier Führungsschienen 9 auf jeder Seite des Vorhangs sind aus einem einstückigen Profil gebildet, wobei jeweils zwei benachbarte Führungsschienen nur eine einzige Trennwand aufweisen. Auf diese Weise werden die Luftkammern an den Seiten abgeschlossen, um die Luft in ihnen festzuhalten, so daß in jeder Luftkammer ein stehendes Luftpolster gebildet wird.Guide rails 9 are formed. The four guide rails 9 on each side of the curtain are formed from a one-piece profile, two adjacent guide rails each having only a single partition. In this way, the air chambers are sealed off on the sides in order to retain the air in them, so that a standing air cushion is formed in each air chamber.

In Fig. 1 ist der Schlitzkasten 11 an dem der Walze 4 entgegengesetzten Ende des Vorhangs angeordnet. Der Schlitzkasten 11 hat eine geschlitzte Oberwand 12, der für jede Vorhangbahn einen in der Breite und Länge im wesentlichen der jeweiligen Vorhangbahn 30 bis 33 angepaßten Schlitz 20 bis 23 aufweist. Die Schlitze 20 bis 23 haben gemäß Fig. 2 auf der gesamten Schlitzbreite Dichtungselemente 13, die sich beidseitig an die jeweiligen Vorhangbahnen 30 bis 33 anlegen. Diese Dichtungselemente 13 bestehen ebenfalls aus Bürsten oder flexiblen Dichtlippen. Es kann auch genügen, diese Dichtungselemente 13 nur in den jeweils äußeren Schlitzen Verzusehen. Auf diese Weise ist die Gesamtheit der Luftkammern nach außen abgeschlossen. Die Höhe des Schlitzkastens 11 gemäß Fig, 1 ist derart bemessen, daß sich das Ende der am weitesten abgewickelten Vorhangbahn 33 nicht am Enden des Schlitzkastens 11 aufstaut, wenn das Ende der am wenigsten abgewickelten Vorhangbahn 30 sich noch außerhalb des Schlitzkastens 11 befindet.In Fig. 1, the slot box 11 is arranged at the end of the curtain opposite the roller 4. The slot box 11 has a slotted top wall 12, which has a slot 20 to 23 adapted in width and length essentially to the respective curtain sheet 30 to 33 for each curtain sheet. According to FIG. 2, the slots 20 to 23 have sealing elements 13 over the entire width of the slot, which bear against the respective curtain sheets 30 to 33 on both sides. These sealing elements 13 also consist of brushes or flexible sealing lips. It may also be sufficient to provide these sealing elements 13 only in the respective outer slots. In this way, all of the air chambers are closed to the outside. The height of the slot box 11 according to FIG. 1 is dimensioned such that the end of the most unwound curtain sheet 33 does not build up at the end of the slot box 11 when the end of the least unwound curtain sheet 30 is still outside the slot box 11.

Die unteren Enden der Vorhangbahnen 30 bis 33 sind jeweils mit einer Beschwerungseinrichtung versehen, die aus zwei Beschwerungsgewichten 7 an den Seitenkanten der Vorhhagbahnen 30 bis 33 und einer Versteifungsschiene 8 besteht, die am Ende der Vorhangbahnen über deren gesamte Breite verläuft, einen geradlinigen Abschluß der unteren Kante der Vorhangbahnen bewirkt und die beiden Beschwerungsgewichte 7 starr miteinander verbindet. Die Beschwerungsgewichte 7 laufen innerhalb der Führungsschienen 9 und sind dadurch nicht sichtbar angeordnet. Sie können ungehindert bis in den Schlitzkasten hineingleiten und brauchen an der Eintrittsstelle nicht die Dichtungselemente 13 an den Schlitzen 20 bis 23 zu durchstoßen, die nur bis zu den Dichtungselementen 10 der Führungsschienen 9 reichen. Die Versteifungsschiene 8 ermöglicht eine exakte Ausrichtung der Vorhangbahnen 30 bis 33 und ein einwandfreies Eintauchen in die Schlitze 20 bis 23 des Schlitzkastens 11. Unter dem Einfluß der Beschwerungsgewichte geben die Dichtungselemente 13 nach, um die Versteifungsschiene hindurchzulassen, und legen sich nach Durchtritt des Vorhangbahnendes abdichtend von beiden Seiten an die jeweilige Vorhangbahnen 30 bis 33. Jedes der Beschwerungsgewichte 7 stellt im vertikalen, quer zur Vorhangbahn verlaufenden Querschnitt ein Sechseck dar, bei dem die zu den Vorhangbahnen parallelen Seiten gegenüber den übrigen vier gleichlangen schrägen Seiten verlängert sind.The lower ends of the curtain sheets 30 to 33 are each provided with a weighting device, which consists of two weighting weights 7 on the side edges of the curtain sheets 30 to 33 and a stiffening rail 8, which runs at the end of the curtain sheets across their entire width, a straight-line termination of the lower Edge of the curtain sheets and rigidly connects the two weights 7 together. The weighting weights 7 run within the guide rails 9 and are therefore not visible. They can slide freely into the slot box and do not need to penetrate the sealing elements 13 at the slots 20 to 23 at the entry point, which only extend as far as the sealing elements 10 of the guide rails 9. The stiffening rail 8 enables an exact alignment of the curtain sheets 30 to 33 and a perfect immersion in the slots 20 to 23 of the slot box 11. Under the influence of the weighting weights, the sealing elements 13 give in to let the stiffening rail through, and lie sealingly after passing through the end of the curtain sheet from both sides to the respective curtain sheets 30 to 33. Each of the weighting weights 7 represents a hexagon in the vertical cross section running transversely to the curtain sheet, in which the sides parallel to the curtain sheets are elongated compared to the other four oblique sides of equal length.

Die Versteifungsschiene 8 ist U-förmig gestaltet und ist durch Klemmung mit dem Vorhangbahnende verbunden. Die untere Kante der Versteifungsschiene ist vorzugsweise V-förmig gestaltet, um das Öffnen und Umklappen der Dichtlippen auf der gesamten Breite des Schlitzes 20 bis 23 beim Eintauchen der Vorhangbahnen in den Schlitzkasten 11 zu erleichtern.The stiffening rail 8 is U-shaped and is connected to the curtain track end by clamping. The lower edge of the stiffening rail is preferably V-shaped in order to facilitate the opening and folding of the sealing lips over the entire width of the slot 20 to 23 when the curtain sheets are immersed in the slot box 11.

Das Ausführungsbeispiel der Fign. 4 und 5 zeigt einen Schlitzkasten 11 im oberen Bereich der Vorhangöffnung. In diesem Fall sind die Längen der einzelnen Vorhangbahnen so aufeinander abgestimmt, daß die Vorhangbahnen im ausgestreckten Zustand auf gleichem Niveau abschließen. Da im aufgewickelten Zustand die Enden der einzelnen Vorhangbahnen 30 bis 33 nicht auf gleicher Höhe abschließen, ist am oberen Ende der Vorhangöffnung 3 der Schlitzkasten 11 angeordnet. Die Beschwerungsgewichte 7 sind in Fig. 4 nicht sichtbar, da sie sich in den Führungsschienen 9 befinden.The embodiment of FIGS. 4 and 5 show a slotted box 11 in the upper region of the curtain opening. In this case, the lengths of the individual curtain sheets are matched to one another in such a way that the curtain sheets terminate at the same level in the extended state. Since the ends of the individual curtain sheets 30 to 33 do not terminate at the same height in the wound state, the slot box 11 is arranged at the upper end of the curtain opening 3. The weighting weights 7 are not visible in FIG. 4 because they are located in the guide rails 9.

Fig. 5 zeigt den Vorhang im aufgewickelten Zustand. Der Schlitzkasten 11 ist bei diesem Ausführungsbeispiel direkt unterhalb der Haltevorrichtung 5 angeordnet. Die Abdichtung der Schlitze kann hierbei alternativ in der geschlitzten Oberwand 12 oder im Schlitzboden 14 vorgesehen sein. Der jeweils andere Schlitzboden, nämlich die geschlitzte Oberwand 12 oder der Schlitzboden 14, kann Reinigungs-und/oder Antistatikelemente aufnehmen, die sich über die gesamte Schlitzbreite der einzelnen Schlitze erstrecken. Die Höhe des Schlitzkastens 11 ist derart bemessen, daß das Ende der am wenigsten aufgewickelten Vorhangbahn 33 sich vollständig im Schlitzkasten 11 befindet, wenn das Ende der am meisten aufgewickelten Vorhangbahn 30 gerade vollständig aufgewickelt ist.Fig. 5 shows the curtain in the wound state. The slot box 11 is arranged directly below the holding device 5 in this embodiment. The sealing of the slots can alternatively be provided in the slotted top wall 12 or in the slot bottom 14. The respective other slot floor, namely the slotted top wall 12 or the slot floor 14, can accommodate cleaning and / or antistatic elements which extend across the entire slot width of the individual slots. The height of the slit box 11 is dimensioned such that the end of the least wound curtain sheet 33 is completely in the slit box 11 when the end of the most wound curtain sheet 30 is just completely wound up.

Das Ausführungsbeispiel der Fig. 6 weist zwei Schlitzkästen 11 a und 11b auf, von dem der Schlitzkasten 11 am oberen Ende und der Schlitzkasten 11b b am unteren Ende der Vorhangöffnung 3 angeordnet ist. Bei zwei Schlitzkästen kann die Bauhöhe der einzelnen Schlitzkästen gegenüber einem einzigen Schlitzkasten erheblich verringert werden, da die Längenunterschiede der einzelnen Vorhangbahnen 30 bis 33 an beiden Enden der Vorhangöffnung 3 aufgefangen und verblendet werden können. Die Führungsschienen 9 sind in diesem Ausführungsbeispiel bis in die Schlitzkästen 11 a, 11 b verlängert. Die von den Vorhangbahnen 30 bis 33 gemeinsam mit den Führungsschienen 9 gebildeten Luftkammern werden jeweils am oberen und unteren Ende des Vorhangs von den Dichtungselementen 13 in den Schlitzen der Schlitzkästen 11 und 11b allseitig abgedichtet.The embodiment of FIG. 6 has two slot boxes 11 a and 11 b, of which the slot box 11 is arranged at the upper end and the slot box 11 b b at the lower end of the curtain opening 3. In the case of two slotted boxes, the overall height of the individual slotted boxes can be considerably reduced compared to a single slotted box, since the differences in length of the individual curtain sheets 30 to 33 can be absorbed and veneered at both ends of the curtain opening 3. The guide rails 9 are extended in this embodiment up to the slot boxes 11 a, 11 b. The air chambers formed by the curtain tracks 30 to 33 together with the guide rails 9 are sealed on all sides at the upper and lower ends of the curtain by the sealing elements 13 in the slots of the slot boxes 11 and 11b.

Das Ausführungsbeispiel der Fig. 7 weist in den Schlitzkästen 11 und 11b parallel zu den ausgestreckten Vorhangbahnen 30 bis 33 verlaufende Trennwände 34, 35 auf. Diese Trennwände 34, 35 bilden getrennte Schlitzkastenkammern 36, 37, in die die einzelnen Vorhangbahnen 30 bis 33 durch die Schlitze 20 bis 23 hindurch eintauchen können. Auf diese Weise sind die einzelnen Luftkammern zwischen den Vorhangbahnen in den Schlitzkästen 11 a, 11 b in der Art einer Labyrinth-Dichtung voneinander getrennt, so daß ein konvektiver Luftaustausch in den Schlitzkästen 11a, 11b nicht möglich ist. Das Ausführungsbeispiel der Fig. 7 weist daher an den Schlitzen 20 bis 23 der Schlitzkästen 11 a,1 1 b keine Dichtungselemente auf.The exemplary embodiment in FIG. 7 has partition walls 34, 35 running in the slot boxes 11 and 11b parallel to the extended curtain sheets 30 to 33. These Partitions 34, 35 form separate slot box chambers 36, 37, into which the individual curtain sheets 30 to 33 can dip through the slots 20 to 23. In this way, the individual air chambers between the curtain sheets in the slot boxes 11a, 11b are separated from one another in the manner of a labyrinth seal, so that a convective air exchange in the slot boxes 11a, 11b is not possible. The embodiment of FIG. 7 therefore has no sealing elements at the slots 20 to 23 of the slot boxes 11 a, 11 b.
