Abstract

A roller shutter which can be rolled up is guided in two vertical guide rails (3), the slats (4) being mounted so as to be additionally rotatable about pivots (5) projecting on the end face in the manner of a blind. Each of the two guide rails (3) is displaceable in the roller shutter plane, and their parallel webs (21) guide the end sections of the slats (4) in the roller shutter position, and, by contrast, only their pivots (5) in the displaced blind position. Provided between each pivot (5) and a common swivel drive (7) is a coupling which in the roller shutter position of the guide rail (3) permits a vertical displacement of the pivots (5) in the roller shutter plane. <IMAGE>

Description

Die Erfindung betrifft einen Rolladen mit einer Aufrolleinrichtung, mit über Zugorgane aneinandergereihten Brettchen, von denen stirnseitig insbesondere mittig angeordnete Drehzapfen abstehen, die mittels eines gemeinsamen Schwenkantriebes verdrehbar sind, mit zwei vertikalen Führungsschienen, die jeweils zwei parallel zueinander verlaufende Stege aufweisen,und mit einer Verschiebeeinrichtung, mittels der die Führungsschienen aus einer Rolladenstellung, in der die Endabschnitteder Brettchen zwischen den Stegen geführt sind, unter Freigabe der Endabschnitte in eine Jalousiestellung verschiebbar sind, in der die Führungsschienen nur die Drehzapfen der Brettchen führen.The invention relates to a roller shutter with a roll-up device, with rows lined up via pulling elements, from which, in particular, centrally located pivot pins protrude on the front side, which can be rotated by means of a common swivel drive, with two vertical guide rails, each having two webs running parallel to one another, and with a displacement device , by means of which the guide rails can be displaced from a roller shutter position in which the end sections of the boards are guided between the webs, with the release of the end sections, into a blind position in which the guide rails guide only the pivot pins of the boards.

Ein derartiger Rolladen ist der EP-A-141805 zu entnehmen. Die Drehzapfen der Brettchen durchsetzen mit einem unrunden, Schraubenflächen aufweisenden Abschnitt korrespondierende Ösen des aus aneinander angelenkten Laschen gebildeten Zugorganes. Diese sind in den verschiebbaren Führungsschienen geführt, sodaß die Verschiebung der Führungsschiene ein Verdrehen der mit Schraubenflächen versehenen Abschnitte der Drehzapfen in den Gelenksösen bewirkt. Beim Verschieben der Führungsschienen werden dabei deren in der Rolladenstellung die Brettchenenden umfassenden Stege von diesen zurückgezogen, bevor die Verschwenkung der Brettchen beginnt. Da eine Gelenksöse jeder Lasche als Langloch ausgebildet ist, können in der Rolladenstellung auch Luftdurchtrittsspalte zwischen den Brettchen gebildet werden. Von Nachteil ist bei diesem Rolladen, daß nicht nur die Führungsschiene, sondern auch das Zugorgan in der gesamten Rolladenhöhe mitverschoben werden muß und die die Brettchenverschwenkung bewirkenden Schraubenflächen der Laschen einer nicht zu vermeidenden Abnützung unterliegen. Diese bewirkt schließlich eine nicht mehr exakt parallele Ausrichtung der Brettchen, die für die Verschiebung der Führungsschienen in die Rolladenstellung unbedingt notwendig ist.Such a roller shutter can be found in EP-A-141805. The pivots of the boards, with an out-of-round section having screw surfaces, pass through corresponding eyelets of the pulling element formed from hinged tabs. These are guided in the displaceable guide rails, so that the displacement of the guide rail causes the sections of the pivot pins provided with screw surfaces to be rotated in the joint eyes. When the guide rails are moved, their webs, which, in the roller shutter position, embrace the ends of the boards, are withdrawn from them before the boards begin to pivot. Since a hinge eye of each tab is designed as an elongated hole, air passage gaps can also be formed between the boards in the roller shutter position. The disadvantage of this roller shutter is that not only the guide rail, but also the pulling element must be moved along the entire height of the roller shutter and the screw surfaces of the tabs causing the board pivoting are subject to unavoidable wear. This ultimately causes the boards to no longer be exactly parallel, which is absolutely necessary for the displacement of the guide rails into the roller shutter position.

Einen sehr ähnlichen Aufbau eines Rolladens zeigt die nicht vorveröffentlichte DE-A- 35 19 957, gemäß der eine Horizontalverschiebung des Zugorganes zuerst eine Freigabe der Brettchenenden und anschließend ein Verschwenken der Brettchen bewirkt, da ebenfalls Schraubenflächen an den Lagerzapfen und den Laschen des Zugorganes zusammenwirken.A very similar structure of a roller shutter is shown in the unpublished DE-A-35 19 957, according to which a horizontal displacement of the tension member first releases the ends of the board and then swivels the board, since screw surfaces on the journals and the tabs of the tension member also interact.

Die Erfindung hat es sich nun zur Aufgabe gestellt, einen Rolladen der eingangs genannten Art zu schaffen, der eine für beide Verwendungsarten möglichst funktionssichere und wartungsfreie Konstruktion aufweist, und die Verschwenkung der Brettchen auch in einer Vielzahl von teilabgesenkten Stellungen des Rolladens ermöglicht.The invention has now set itself the task of creating a roller shutter of the type mentioned, which has a functionally reliable and maintenance-free construction for both types of use, and allows the pivoting of the board in a variety of partially lowered positions of the roller shutter.

Erfindungsgemäß wird dies dadurch erreicht, daß zwischen jedem Drehzapfen und dem gemeinsamen Schwenkantrieb eine Kupplung vorgesehen ist, die in der Rolladenstellung der Führungsschiene hinsichtlich einer Vertikalverschiebung des Drehzapfens in der Führungsschiene außer Eingriff ist.According to the invention, this is achieved in that a coupling is provided between each pivot pin and the common pivot drive, which is disengaged in the roller shutter position of the guide rail with respect to a vertical displacement of the pivot pin in the guide rail.

Durch die Ausbildung der Kupplung zwischen dem Schwenkantrieb und jedem Drehzapfen ist trotz der zweiten Verwendungsmöglichkeit als jalousie ein unabhängiger und ungehinderter Rolladenbetrieb in herkömmlicher Weise gegeben, wobei der Schwenkantrieb eine funktionelle Ergänzung darstellt und nicht durch die Verschiebung der Führungsschiene bewirkt wird.Due to the design of the coupling between the swivel drive and each pivot, independent and unimpeded roller shutter operation is provided in a conventional manner despite the second possible use as a blind, the swivel drive being a functional addition and not being caused by the displacement of the guide rail.

Es ergibt sich zusätzlich noch der Vorteil, daß eine Verschwenkung der Brettchen auch dann möglich ist, wenn der Rolladen in bestimmten, teilabgesenkten Stellungen ist.There is an additional advantage that the boards can also be pivoted when the roller shutter is in certain, partially lowered positions.

In einer bevorzugten Ausführung ist dabei vorgesehen, daß der Drehzapfen verdrehfest in einen diametralen Schlitz einer Kupplungswelle des Schwenkantriebes eingreift, wobei die Schlitze aller Kupplungswellen in der Rolladenstellung miteinander fluchten. Somit ist zwar der verdrehfeste Eingriff beim Wechsel von der Rolladenstellung in die Jalousiestellung und umgekehrt sichergestellt, in der Rolladenstellung ist jedoch die vertikale Bewegung der Drehzapfen und damit der Brettchen möglich, sodaß der in den seitlichen Führungsschienen geführte Rolladen auf-und abbewegt werden kann.In a preferred embodiment it is provided that the pivot pin engages in a diametrical slot of a coupling shaft of the pivot drive in a rotationally fixed manner, the slots of all coupling shafts being aligned with one another in the roller shutter position. Thus, the torsion-proof engagement when changing from the roller shutter position to the blind position and vice versa is ensured, but in the roller shutter position the vertical movement of the pivot pins and thus of the boards is possible, so that the roller shutter guided in the side guide rails can be moved up and down.

In bevorzugter Ausführung ist weiters vorgesehen, daß jede der beiden verschiebbaren Führungsschienen U-förmig ausgebildet ist, und in dem sich senkrecht zur Rolladenebene erstreckenden Quersteg pro Kupplungswelle des Schwenkantriebes eine Durchtrittsöffnung aufweist. Jede Kupplungswelle ist dadurch rahmenfest gelagert, wobei sie in beliebiger Weise für die gemeinsame Verschwenkung aller Kupplungswellen ausgebildet sein kann.In a preferred embodiment, it is further provided that each of the two displaceable guide rails is U-shaped and has a passage opening in the transverse web extending perpendicularly to the roller shutter plane for each coupling shaft of the swivel drive. Each coupling shaft is thereby fixed to the frame, and it can be designed in any way for the joint pivoting of all coupling shafts.

Für die Verschiebung jeder Führungsschiene sind in bevorzugter Ausgestaltung zumindest zwei parallel verschwenkbare Steuernocken vorgesehen, die vom Schwenkantrieb abhängig bewegbar sind. Das heißt, daß die Verschwenkung der Steuernocken gesperrt ist, solange die Brettchen nicht ihre Rolladenstellung eingenommen haben. Die Verschwenkung der Steuernocken ist somit nur möglich, bevor der Schwenkantrieb wirksam werden kann, und nachdem die Brettchen wieder in die Rolladenebene zurückgedreht worden sind.In a preferred embodiment, at least two control cams which can be pivoted in parallel are provided for the displacement of each guide rail and can be moved as a function of the rotary drive. This means that the pivoting of the control cams is blocked as long as the boards have not taken their roller shutter position. The pivoting of the control cams is therefore only possible before the swivel drive can take effect and after the boards have been rotated back into the roller shutter level.

Die Steuernocken beaufschlagen vorzugsweise die Führungsschienen nur in einer Richtung, nämlich in der Verschieberichtung in die Rolladenstellung. Für die Rückführung ist in dieser Ausführung eine Federbeaufschlagung vorgesehen, die die Führungsschiene bei Rückschwenkung der Steuernocken diesen folgen läßt. Selbstverständlich könnte aber auch die Zwangsmitnahme der Führungsschiene durch die Steuernocken in beiden Richtungen erfolgen.The control cams preferably act on the guide rails only in one direction, namely in the direction of displacement into the shutter position. In this version, spring action is provided for the return, which allows the guide rail to follow the control cam when the control cams are pivoted back. Of course, the guide cam could also be forced in both directions by the control cam.

In einer zweiten Ausführung des erfindungsgemäßen Rolladens wird die Kupplung der Brettchen zum Schwenkantrieb dadurch erreicht, daß jeder Drehzapfen ein Zahnrad trägt, und an einem der Stege der Führungsschiene eine innere Längsverzahnung vorgesehen ist, wobei die Zahnräder in der Jalousiestellung der Führungsschiene in die Längsverzahnung eingerückt und in der Rolladenstellung ausgerückt sind. In dieser Ausführung erfolgt die Verschwenkung der Brettchen in der Jalousiestellung dann über die Aufrolleinrichtung, d. h. ein Hochziehen (oder Absenken) des Rolladens um die Umfangslänge des Zahnrades bewirkt eine Verdrehung um 360°.In a second embodiment of the roller shutter according to the invention, the coupling of the boards to the swivel drive is achieved in that each pivot pin carries a gear and an internal longitudinal toothing is provided on one of the webs of the guide rail, the gearwheels being engaged in the longitudinal toothing in the blind position of the guide rail and are disengaged in the shutter position. In this version, the swiveling of the boards in the blind position then takes place via the reel-up device, ie a raising (or lowering) of the roller shutter around the circumferential length of the gearwheel causes a rotation of 360 °.

Als Zugorgan weist der Rolladen insbesondere eine stabile Laschenkette auf, in der der Achsabstand der Gelenksbolzen der Laschen der Höhe jeweils eines Brettchens entspricht. Ein Formschluß zwischen den Brettchenschmalseiten, die z.B. V-förmig verlaufen, wird durch Ausbildung eines Langloches in jeder Lasche ermöglicht, dessen Länge die Breite eines zwischen den Brettchen in der Rolladenstellung erzielbaren Luftdurchtrittsspaltes bestimmt. In diesem Fall ist dann bevorzugt vorgesehen, daß der Achsabstand zwischen zwei Kupplungswellen der Höhe eines Brettchens zuzüglich der Breite des Luftdurchtrittspaltes entspricht.As a pulling element, the roller shutter has in particular a stable link chain, in which the center distance of the hinge pins of the links corresponds to the height of one board. A form fit between the narrow sides of the board, which for example run in a V-shape, is made possible by forming an elongated hole in each tab, the length of which determines the width of an air passage gap which can be achieved between the boards in the roller shutter position. In this case, it is preferably provided that the center distance between two coupling shafts corresponds to the height of a board plus the width of the air passage gap.

Nachstehend wird nun die Erfindung an Hand der Figuren der beiliegenden Zeichnungen näher beschrieben, ohne darauf beschränkt zu sein.The invention will now be described in more detail below with reference to the figures in the accompanying drawings, without being limited thereto.

Ein erfindungsgemäßer Rolladen weist einen Rahmen 2 auf, der an einem Fenster 1 od. dgl. vorgesehen ist. Der Rahmen 2 kann dabei als eigener am Fensterstock anzubringender oder bereits im Stockprofil integrierter Teil ausgebildet sein. Jeder der beiden sich vertikal erstreckenden Teile des Rahmens 2 weist, wie aus den Zeichnungen ersichtlich, eine in der Rolladenebene sich erstreckende Nut 38 auf, die zu den Brettchen 4 des Rolladens hin offen ist. In der Nut 38 ist eine U-förmige Führungsschiene 3 angeordnet, die zwei zueinander parallele Stege 21 und einen Quersteg 13 aufweist. Die Führungsschiene 3 ist in der Nut 38 in der Rolladenebene horizontal zwischen einer Rolladenstellung und einer Jalousiestellung verschiebbar, wobei in der Rolladenstellung (Fig. 1) die Stege 21 der Führungsschiene 3 die Endabschnitte der Brettchen 4 einfassen, sodaß eine herkömmliche, massive Rolladenführung gegeben ist. Die Stege 21 geben in der in die Jalousiestellung nach Fig. 2 zurückgezogenen Führungsschiene 3 die Endabschnitte der Brettchen 4 frei, sodaß diese um Drehzapfen 5 verschwenkbar sind. Diese Drehzapfen 5 ragen von der Stirnseite der Brettchen 4 mittig ab und durchsetzen ein im Inneren der Führungsschiene 3 angeordnetes Zugorgan 6 der Aufrolleinrichtung des Rolladens. Somit werden in der Jalousiestellung nur mehr die Drehzapfen 5 bzw. das Zugorgan 6 von den Stegen 21 eingefaßt. Die Brettchen 4 können in beliebiger Art aus Holz, Metall oder Kunststoff gefertigt sein, wie dargestellt sind deren Längsschmalseiten dachförmig abgestuft bzw. ausgekehlt, sodaß sie in völlig geschlossener Stellung (Fig. 5) formschlüssig ineinander greifen.A roller shutter according to the invention has a frame 2 which is provided on a window 1 or the like. The frame 2 can be designed as a separate part to be attached to the window frame or already integrated in the frame profile. Each of the two vertically extending parts of the frame 2 has, as can be seen from the drawings, a groove 38 which extends in the plane of the roller shutter and which is open towards the boards 4 of the roller shutter. A U-shaped guide rail 3 is arranged in the groove 38 and has two mutually parallel webs 21 and a transverse web 13. The guide rail 3 is horizontally displaceable in the groove 38 in the roller shutter plane between a roller shutter position and a blind position, the webs 21 of the guide rail 3 enclosing the end sections of the boards 4 in the roller shutter position (FIG. 1), so that a conventional, massive roller shutter guide is provided . The webs 21 give in the retracted into the blind position according to FIG. 2 the guide rail 3 End portions of the board 4 free, so that they can be pivoted about pivot 5. These pivots 5 protrude centrally from the end face of the boards 4 and penetrate a pulling element 6 of the rolling device of the roller shutter arranged in the interior of the guide rail 3. Thus, in the blind position, only the pivots 5 or the tension member 6 are enclosed by the webs 21. The boards 4 can be made in any manner from wood, metal or plastic, as shown, their longitudinal narrow sides are stepped or grooved so that they engage in a form-fitting manner in a completely closed position (FIG. 5).

Um nun einerseits in der Rolladenstellung gemäß Fig. 1, die Brettchen 4 in üblicher Weise vollständig auf- und abrollen, beliebige Zwischenstellungen einstellen und Luftdurchtrittsspalte 31 (Fig. 5) vorsehen zu können, und andererseits in der Jalousiestellung die Brettchen gemeinsam vom Schwenkantrieb 7 aus verdrehen zu können, ist jeder Drehzapfen 5 getrennt an den Schwenkantrieb 7 lösbar angekuppelt. Zu diesem Zweck ist, wie aus den Fig. 1, 2, 3 und 5 besonders gut ersichtlich, pro Drehzapfen 5 eine Kupplungswelle 8 vorgesehen, die am freien Ende ein Zahnrad 11 trägt. Jede Kupplungswelle 8 durchsetzt eine Öffnung im Quersteg 13 und ist im Rahmen 2 drehbar gelagert. Das Kupplungsende der Kupplungswelle 8 ist mit einem sich diametral erstreckenden Schlitz 9 versehen, in den eine am Ende des Drehzapfens 5 diametral ausgebildeter flacher Steg 10 eingreift. Die Zahnräder 11 aller Kupplungswellen 8 sind über eine Kette 12 gekoppelt, deren Bewegung alle Kupplungswellen gleichzeitig und gleichsinnig verdreht.In order to be able to roll the boards 4 up and down completely in the usual way in the roller shutter position according to FIG. 1, to set any intermediate positions and to provide air passage gaps 31 (FIG. 5), and on the other hand in the blind position the boards together from the swivel drive 7 To be able to rotate, each pivot 5 is separately detachably coupled to the swivel drive 7. For this purpose, as can be seen particularly well from FIGS. 1, 2, 3 and 5, a coupling shaft 8 is provided per pivot 5, which carries a gear 11 at the free end. Each coupling shaft 8 passes through an opening in the crosspiece 13 and is rotatably mounted in the frame 2. The coupling end of the coupling shaft 8 is provided with a diametrically extending slot 9, in which a flat web 10, which is formed diametrically at the end of the pivot pin 5, engages. The gears 11 of all clutch shafts 8 are coupled via a chain 12, the movement of which rotates all clutch shafts simultaneously and in the same direction.

In der Rolladenstellung ist eine Verschwenkung der Brettchen 4 unmöglich, jedoch muß ihre Vertikalbewegung gewährleistet sein. Dies ist dann der Fall, wenn gemäß Fig. 1 die sich diametral erstreckenden Schlitze 9 aller Kupplungswellen 8 in der Rolladenebene liegen, da dann wie in Fig. 5 gezeigt, der Austritt der Stege 10 aus den Schlitzen 9 erfolgen kann. Es versteht sich, daß für die Verschwenkung der Brettchen 4 in der Jalousieverwendung die Stege 10 der Drehzapfen 5 wieder in die Schlitze 9 der Kupplungswellen 8 eingetreten sein müssen. Das bedeutet, daß bei vollständig geschlossenem Rolladen gemäß Fig. 5 die Brettchen 4 angehoben werden, um mit den Stirnseiten außer Eingriff zu kommen, also in jene Stellung gebracht werden, in der die Luftdurchtrittsspalte 31 gebildet sind. DAs Zugorgan 6 setzt sich hierfür aus einzeln aneinandergelenkten Laschen 18 zusammen, wobei jede Lasche 18 einseitig ein Langloch 19 aufweist, sodaß für den Gelenksbolzen 10 ein Verschiebeabstand a freibleibt, der der Breite des Luftdurchtrittsspaltes 31 entspricht, wobei der Achsabstand der Kupplungswellen 8 der Brettchenhöhe einschließlich des Abstandes a gleichkommt.In the roller shutter position, pivoting of the boards 4 is impossible, but their vertical movement must be ensured. This is the case if according to Fig. 1, the diametrically extending slots 9 of all coupling shafts 8 are in the roller shutter plane, since then, as shown in Fig. 5, the webs 10 can emerge from the slots 9. It goes without saying that the webs 10 of the pivot pins 5 must have re-entered the slots 9 of the coupling shafts 8 for the pivoting of the boards 4 in the use of the blinds. This means that when the roller shutter is completely closed according to FIG. 5, the boards 4 are raised in order to disengage the end faces, that is to say are brought into the position in which the air passage gaps 31 are formed. For this purpose, the pulling element 6 is composed of individually hinged tabs 18, each tab 18 having an elongated hole 19 on one side, so that a displacement distance a remains free for the pivot pin 10, which corresponds to the width of the air passage gap 31, the center distance of the coupling shafts 8 including the board height equals the distance a.

Aus dieser Eingriffsstellung der Drehzapfen 5 in die Kupplungswellen 8 wird die Führungsschiene 3 zurückgezogen, die in der Rolladenstellung durch zumindest zwei Steuernocken 14 gesperrt ist. Diese sind auf Achsen 15 im Rahmen 2 gelagert und über eine Zugstange 17 mit Querachsen 16 gemeinsam verschwenkbar. In Fig. 3 und 4 ist strichliert die verschwenkte Stellung der Steuernocken 14 dargestellt, wobei die Führungsschiene 3 unter der Wirkung mehrerer Druckfedern 32 zurückgeschoben ist und die in Fig. 2 ersichtliche Lage einnimmt.From this engagement position of the pivot pin 5 in the coupling shafts 8, the guide rail 3 is withdrawn, which is locked in the roller shutter position by at least two control cams 14. These are mounted on axles 15 in frame 2 and can be pivoted together with transverse axles 16 via a pull rod 17. 3 and 4, the pivoted position of the control cams 14 is shown in broken lines, the guide rail 3 being pushed back under the action of a plurality of compression springs 32 and assuming the position shown in FIG. 2.

In der Sperrstellung der Steuernocken 14 ist die Zugstange 17 in ihrer tiefsten Position vorgesehen. Ein an die Zugstange 17 an geeigneter Stelle angelenkter Steuerhebel 23, der auf einer Achse 24 schwenkbar gelagert und von einer schematisch angedeuteten Feder 25 nach unten beaufschlagt ist, liegt mit seinem zweiten Arm 26 im Verschiebeweg eines vertikal verstellbaren Sperrschiebers 27.In the locked position of the control cam 14, the pull rod 17 is provided in its lowest position. A control lever 23 articulated to the pull rod 17 at a suitable point, which is pivotably mounted on an axis 24 and is urged downwards by a schematically indicated spring 25, lies with its second arm 26 in the displacement path of a vertically adjustable locking slide 27.

Dieser ist mittels eines Seilzuges 30 einerseits bzw. über eine Druckfeder 28 andererseits verschiebbar. Der Sperrschieber 27 ist mit einem Längsschlitz 29 versehen, in dem ein Ende der Kette 12 verschiebbar geführt ist, wobei sich die Druckfeder 28 zwischen dem Ende der Kette 12 und dem Sperrschieber 27 abstützt. Das erste Ende der Kette 12, die vom Sperrschieber 27 kommend über das oberste Zahnrad 11 nach unten umgelenkt alle Zahnräder 11 verbindet, ist an einer rahmenfesten Rückhaltefeder 22 befestigt. Somit wird bei Betätigung des Seilzuges 30 der Sperrschieber 27 nach unten gezogen, wobei die Druckfeder 28 komprimiert wird, ohne die Kette 12 vorerst zu bewegen, da die Verdrehung der Brettchen 4 noch nicht möglich ist. Der Sperrschieber 27 schwenkt jedoch unter Spannung der Feder 25 den Steuerhebel 23, wodurch die Zugstange 17 aufwärtsgeschoben und die Steuernocken 14 abwärts geschwenkt werden. Die damit freigegebene Führungsschiene 3 weicht durch die Druckfedern 32 aus und ermöglicht die Verschwenkung der Brettchen 4, die durch ein weiteres Ziehen am Seilzug 30 erfolgt, da der Sperrschieber 27 nach Kompression der Feder 28 die Kette 12 bewegt. Der Schwenkwinkel der Brettchen 4 kann somit problemlos gewählt und eingestellt werden.This can be moved by means of a cable 30 on the one hand or via a compression spring 28 on the other hand. The locking slide 27 is provided with a longitudinal slot 29 in which one end of the chain 12 is slidably guided, the compression spring 28 being supported between the end of the chain 12 and the locking slide 27. The first end of the chain 12, which, coming from the locking slide 27 and deflects downward via the uppermost gearwheel 11, connects all the gearwheels 11, is fastened to a retaining spring 22 fixed to the frame. Thus, when the cable 30 is actuated, the locking slide 27 is pulled down, the compression spring 28 being compressed without initially moving the chain 12, since the twisting of the boards 4 is not yet possible. The locking slide 27, however, pivots the control lever 23 under tension of the spring 25, as a result of which the pull rod 17 is pushed up and the control cams 14 are pivoted downward. The guide rail 3 thus released yields through the compression springs 32 and enables the pivoting of the boards 4, which takes place by a further pull on the cable 30, since the locking slide 27 moves the chain 12 after compression of the spring 28. The swivel angle of the board 4 can thus be easily selected and adjusted.

Für die Rückführung in die Rolladenverwendung wird der Seilzug 30 freigegeben, und die Rückholfeder 22 schwenkt alle Brettchen in ihre Rolladenstellung, worauf in weiterer Folge die Druckfeder 28 den Sperrschieber 27 weiter verschiebt, so daß durch die Feder 25 auch der Steuerhebel 23 zurückholbar ist, der die Hubstange 17 nach unter verschiebt und die Steuernocken 14 aufwärts verschwenkt. Diese drücken die Führungsschiene 3 nach vorne, sodaß die Endabschnitte der Brettchen 4 eingefaßt, und die nicht gezeigte Aufrolleinrichtung einsehbar ist.For the return to the roller shutter use, the cable 30 is released, and the return spring 22 pivots all the boards into their roller shutter position, whereupon the compression spring 28 further displaces the locking slide 27, so that the control lever 23 can also be retrieved by the spring 25 the lifting rod 17 moves down and the control cam 14 pivoted upwards. These push the guide rail 3 forward so that the end portions of the board 4 are edged and the reel-up device, not shown, can be seen.

In Fig. 6 und 7 ist eine weitere Ausführung dargestellt. Die Führungsschiene 3 ist wiederum über Steuernocken 14 und einen nicht weiter ausgeführten Betätigungsmechanismus zwischen der Rolladenstellung nach Fig. 6 und der Jalousiestellung nach Fig. 7 verschiebbar. Jeder das Zugorgan 6 durchsetzende Drehzapfen 5 trägt jedoch direkt ein Zahnrad 40. Diesem ist als Teil des Schwenkantriebes eine Verzahnung, beispielsweise eine Zahnstange 41 an der Innenseite eines Steges 21 der Führungsschiene 3 zugeordnet. Die Zahnstange 41 ist daher mit der Führungsschiene 3 verschiebbar, sodaß sie gemäß Fig. 6 in der Rolladenstellung außer Eingriff mit den Zahnrädern 40 und in der Jalousiestellung gemäß Fig. 7 in Eingriff mit den Zahnrädern 40 steht. Die Verdrehung der Brettchen 4 kann über das Zugorgan 6 erfolgen, dessen Bewegung die Zahnräder 40 in der Zahnstange 41 abrollen läßt. Es wäre aber ebenso denkbar, stattdessen die Zahnstange 41 vertikal zu verschieben.6 and 7 a further embodiment is shown. The guide rail 3 can in turn be displaced between the roller shutter position according to FIG. 6 and the blind position according to FIG. However, each pivot pin 5 passing through the pulling element 6 directly carries a gear wheel 40. As part of the swivel drive, this is assigned a toothing, for example a toothed rack 41 on the inside of a web 21 of the guide rail 3. The rack 41 can therefore be moved with the guide rail 3, so that it is disengaged from the gears 40 in the roller shutter position according to FIG. 6 and in engagement with the gears 40 in the blind position according to FIG. 7. The twisting of the boards 4 can take place via the traction element 6, the movement of which allows the gear wheels 40 to roll in the rack 41. However, it would also be conceivable to move the rack 41 vertically instead.
