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 und über Zugorgane aneinandergereihten Brett­chen, die in zwei vertikalen Führungsschienen geführt und um stirnseitig abstehende Drehzapfen mittels eines gemein­samen Schwenkantriebes verdrehbar gelagert sind, wobei jede Führungsschiene zwei parallel zur Rolladenebene ver­laufende Stege aufweist, und ihr für die Brettchenver­schwenkung eine Verschiebeeinrichtung zur Verstellung der Führungsschiene zwischen der Rolladenstellung und einer Jalousiestellung zugeordnet ist.The invention relates to a roller shutter with a roll-up device and strings lined up by pulling elements, which are guided in two vertical guide rails and rotatably mounted about front projecting trunnions by means of a common swivel drive, each guide rail having two webs running parallel to the roller shutter plane, and one for pivoting the board Sliding device for adjusting the guide rail between the roller shutter position and a blind position is assigned.

Ein derartiger Rolladen ist beispielsweise der EP-B-52 320 zu entnehmen. Bei einzelnen Brettchen sind dort nach Art von Lamellen ausgebildet und jeweils an einem Paar von Zugorganen aufgehängt. Um in der Rolladenstellung und der Jalousiestellung eine verbesserte Führung der Brettchen zu erzielen, ist jedes Brettchen stirnseitig mit einem Zapfen versehen, der in jeder Stellung an zwei Vertikal­stegen anliegend geführt ist und unterschiedliche Durch­messer in horizontaler und vertikaler Richtung aufweist. Um dem Rechnung zu tragen, ist ein Vertikalsteg in Abstand zum weiten durch Federbeaufschlagung oder entlang schräger Führungen durch sein Eigengewicht verstellbar, wobei er die Zapfen beaufschlagt.Such a roller shutter can be found, for example, in EP-B-52 320. In the case of individual boards there are designed in the manner of lamellae and each is suspended from a pair of traction elements. In order to achieve improved guidance of the boards in the roller shutter position and the blind position, each board is provided on the end face with a pin which is guided in two positions against each vertical bar and has different diameters in the horizontal and vertical directions. In order to take this into account, a vertical web can be adjusted at a distance from it by spring loading or along oblique guides by its own weight, whereby it acts on the pins.

Zueinander im Abstand verstellbare Führungsstege, die die ständige Führung von schwenkbaren Jalousielamellen bewir­ken, indem sie deren Enden direkt umgreifen, sind aus der DE-A-19 10 198 bekannt. Die hier beschriebene Jalousie hat aber keine Rolladenfunktion, da die Lamellen horizon­tal zu einem oberen Stapel hochgezogen werden.DE-A-19 10 198 is known from guide webs which are adjustable at a distance from one another and which bring about the constant guiding of pivotable blind slats by gripping their ends directly. The blind described here does not have a roller shutter function, since the slats are pulled up horizontally to an upper stack.

Zueinander verstellbare Führungsstege der Führungsschienen sind weiters (DE-C- 8275) auch bei einfachen, nicht ver­schwenkbaren Rolläden bekannt, wo eine federnde Auspres­sung eines Führungssteges an die Brettchen die Entstehung von Windgeräuschen unterbinden soll.Mutually adjustable guide webs of the guide rails are also known (DE-C-8275) even in the case of simple, non-pivotable roller shutters, where resilient pressing out of a guide web on the boards is intended to prevent wind noise.

Gewöhnliche Rolläden mit massiven Brettchen, insbesondere Holzbrettchen, die in festen Führungsschienen beweglich sind, sollen einbruchshemmend wirken, wobei bei herunter­gelassenem Rolladen jedoch auch ein Luft- und Lichtdurch­tritt gegeben sein soll. Die Brettchen sind daher über längenveränderliche, meist flexible Verbindungsteile an­einandergehängt, sodaß sie bei Auflage des untersten Brett­chens dicht übereinanderliegen, in jeder Zwischenstellung jedoch Luftspalten freilassen, die allerdings nicht die Größe der Schlitze von Jalousien aufweisen können.Ordinary roller shutters with solid boards, in particular wooden boards, which are movable in fixed guide rails, are intended to have a burglar-proof effect, but with the roller shutters lowered, there should also be air and light passage. The boards are therefore attached to one another via variable-length, usually flexible connecting parts, so that they lie one above the other when the bottom board is placed on top, but leave air gaps in any intermediate position, which, however, cannot have the size of the slits of blinds.

Die Erfindung hat es sich nun zur Aufgabe gestellt, einen Rolladen der eingangs genannten Art zu schaffen, der in der Rolladenstellung eine hohe Einbruchshemmung durch massive Führungen und gegebenenfalls geringe Luftdurch­trittsspalte aufweist, und dessen Brettchen dennoch über eine gemeinsame Schwenkeinrichtung in eine Jalousiestellung verschwenkbar sind, die die üblichen verstellbaren Luft- und Lichtdurchtrittsspalte besitzt.The invention has now set itself the task of creating a roller shutter of the type mentioned, which has a high burglar resistance in the roller shutter position by massive guides and possibly small air passage gaps, and the boards are still pivoted via a common pivoting device in a blind position, the has the usual adjustable air and light passage gaps.

Erfindungsgemäß wird dies nun dadurch gelöst, daß jede der beiden Führungsschienen in der Rolladenebene verschiebbar ist, wobei deren parallele Stege in der Rolladenstellung jeweils die Endabschnitte der Brettchen, und in der Jalou­siestellung von den Brettchen distanziert nur deren Dreh­zapfen führen, daß zwischen jedem Drehzapfen und dem ge­meinsamen Schwenkantrieb eine Kupplung vorgesehen ist, die in der Rolladenstellung der Führungsschiene zumindest im Sinne einer Vertikalverschiebung des Drehzapfens in der Rolladenebene außer Eingriff ist.According to the invention, this is now achieved in that each of the two guide rails is displaceable in the roller shutter plane, the parallel webs of which in the roller shutter position respectively the end sections of the boards, and in the blind position distanced from the boards only their pivot leads that between each pivot and the common swivel drive a coupling is provided, which is in the roller shutter position of the guide rail at least in the sense of a vertical displacement of the pivot in the roller shutter plane out of engagement.

Die erfindungsgemäße Ausführung ermöglicht es somit die Endabschnitte der Brettchen bei Verwendung als Rolladen in der Art einfacher Rolladen in Führungsschienen zu füh­ren, deren Seitenstege einen konstanten Abstand zueinander aufweisen, wodurch eine Konstruktion mit beliebig hoher Stabilität erreicht werden kann, die je nach Schwere der Ausführung in hoher Weise einbruchshemmend ist. Die opti­male Funktion der Einrichtung ist aber auch in der zweiten Verwendungsart als Jalousie gegeben, sobald die Führungs­schiene von den Endabschnitten der Brettchen abgezogen ist, da dann die Brettchen nur mehr an den Drehzapfen geführt um einen beliebigen Winkel verschwenkt werden können. Da­bei können auch die Dicke und Breite der Brettchen nach Rolladengesichtspunkten ausgewählt werden. Es ergibt sich zusätzlich noch der Vorteil, daß eine Verschwenkung der Brettchen auch dann möglich ist, wenn der Rolladen in be­stimmten, teilabgesenkten Stellungen ist.The embodiment according to the invention thus makes it possible to guide the end sections of the boards when used as roller shutters in the manner of simple roller shutters in guide rails, the side webs of which are at a constant distance from one another have, whereby a construction can be achieved with any high stability, which is highly burglar-resistant depending on the severity of execution. The optimal function of the device is also given in the second type of use as a blind, as soon as the guide rail is pulled off the end sections of the boards, since then the boards can only be pivoted by any angle guided on the pivot. The thickness and width of the boards can also be selected from the perspective of the roller shutter. There is also the additional advantage that pivoting of the boards is also possible 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. Da die Führungsschiene in der Rolladenebene ausweicht, ist eine bevorzugte, ausbalancier­te Anordnung der Drehzapfen jeweils mittig an der Stirn­seite des Brettchens möglich.In a preferred embodiment it is provided that the pivot pin engages in a diametrical slot of a coupling shaft of the swivel drive, 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 pin and thus the board is possible, so that the roller shutter guided in the side guide rails can be moved up and down. Since the guide rail deviates in the level of the roller shutter, a preferred, balanced arrangement of the pivot pins is possible in the middle of the face of the board.

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°. Auch die Verschiebung der Führungs­schiene selbst könnte den Schwenkantrieb der Brettchen in der Jalousiestellung bewirken, wenn die Kupplungswel­len wiederum rahmenfest drehbar gelagert sind und Durch­trittsöffnungen im Quersteg der Führungsschiene verdreh­ fest durchsetzen, und in einem Endabschnitt Schrauben­flächen mit hoher Steigung aufweisen. Bis zur Freigabe der Brettchen von der Führungsschiene bleiben dabei die Kupplungswellen in der Rolladenstellung, d. h. ihre Schlitze liegen in der Rolladenebene, und ein weiteres Zurückschieben der Führungsschiene bewirkt dann aufgrund der Schraubenflächen eine Verdrehung der Kupplungswellen.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 °. The displacement of the guide rail itself could also cause the boards to pivot in the blind position if the coupling shafts are in turn rotatably mounted on the frame and twist through openings in the crossbar of the guide rail push through firmly and have screw surfaces with a high pitch in one end section. The coupling shafts remain in the roller shutter position until the boards are released from the guide rail, ie their slots lie in the roller shutter plane, and further pushing back of the guide rail then causes the coupling shafts to twist due to the screw surfaces.

Eine bevorzugte Ausgestaltung aller Ausführungen sieht weiters vor, daß jeder Drehzapfen innerhalb der Führungs­schiene das Zugorgan der Aufrolleinrichtung durchsetzt, das miteinander gelenkig verbundene Laschen aufweist, wo­bei der Achsabstand der Gelenksbolzen der Höhe eines Brett­chens entspricht. Das Zugorgan kann damit als stabile Laschenkette ausgebildet sein, wobei die Laschenbreite der Brettchendicke entsprechen kann und die Laschenkette in der Führungsschiene gegen seitliche Auslenkung gesichert geführt ist. Ein Formschluß zwischen den Brettchenschmal­seiten, die z. B. V-förmig verlaufen, kann dabei dadurch erreicht werden, daß eines der Drehlager jeder Lasche als Langloch ausgebildet ist, dessen Länge die Höhe eines zwischen den Brettchen in der Rolladenstellung erziel­baren Luftdurchtrittsspaltes bestimmt, wodurch bei völlig geschlossenem Rolladen vor der Verschwenkung der Brettchen diese soweit angehoben werden, daß die Luftdurchtritts­spalte gegeben sind. In diesem Fall ist dann vorgesehen, daß der Achsabstand zwischen zwei Kupplungswellen dem Achsabstand zwischen zwei Gelenksbolzen zuzüglich der Höhe des Luftdurchtrittsspaltes entspricht.A preferred embodiment of all versions further provides that each pivot pin in the guide rail passes through the pulling element of the retractor, which has hinged tabs, the center distance of the hinge pins corresponding to the height of a board. The traction element can thus be designed as a stable link chain, the link width can correspond to the board thickness and the link chain is guided in the guide rail so as to be secured against lateral deflection. A positive connection between the narrow sides of the board, the z. B. V-shaped, can be achieved in that one of the pivot bearings of each tab is designed as an elongated hole, the length of which determines the height of an air passage gap achievable between the boards in the roller shutter position, which means that when the roller shutters are completely closed, before pivoting the boards are raised so far that the air passage gaps are given. In this case it is then provided that the center distance between two coupling shafts corresponds to the center distance between two hinge pins plus the height of the air passage gap.

Im zweiten vertikalen Rahmenteil des Rolladens ist gegebenen­falls eine spiegelbildliche Ausgestaltung vorgesehen, wo­bei die Bewegungsabläufe miteinander gekoppelt sind.A mirror-image configuration is optionally provided in the second vertical frame part of the roller shutter, the movement sequences being coupled to one another.

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.

Die Fig. 1 zeigt einen Horizontalschnitt durch einen Teil des Rolladens in Rolladenstellung nach der Linie I-I der Fig. 3, die Fig. 2 einen Horizontalschnitt entsprechend Fig. 1 in Jalousiestellung nach der Linie II-II der Fig. 3, die Fig. 3 und 4 Vertikalschnitte nach den Linien III-III und IV-IV der Fig. 1, wobei die Jalousiestellung jeweils strichliert gezeichnet ist, die Fig. 5 eine Darstellung gemäß Fig. 3 in einer völlig geschlossenen Rolladenstellung, und die Fig. 6 und 7 zeigen Schnitte gemäß Fig. 1 und 2 durch ein zweites Ausführungsbeispiel.1 shows a horizontal section through part of the roller shutter in the roller shutter position along the line II of FIG. 3, FIG. 2 shows a horizontal section corresponding to FIG. 1 in the blind position along the line II-II of FIG. 3, FIG. 3 and 4 vertical sections along the lines III-III and IV-IV of FIG. 1, the blind position being shown in broken lines, FIG. 5 is a representation according to FIG. 3 in a completely closed roller shutter position, and FIGS. 6 and 7 show 1 and 2 through a second embodiment.

Ein erfindungsgemäßer Rolladen weist einen Rahmen 2, 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 Rahmen 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 from the center of the end face of the boards 4 and penetrate a pulling element 6 of the rolling device of the roller shutter arranged inside 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 up and unwind the boards 4 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 hiefür 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. The pulling element 6 is made up of individually hinged tabs 18, each tab 18 having an elongated hole 19 on one side, so that there remains a displacement distance a 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 is effected by a further pull on the cable 30, since the locking slide 27 moves the chain 12 after compression of the spring 28. The pivot 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 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 is in turn displaceable 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 associated with 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 displaced with the guide rail 3, so that, according to FIG. 6, the toothed wheels 40 are out of engagement in the roller shutter position and the toothed wheels 40 are in engagement 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 toothed wheels 40 to roll in the toothed rack 41. However, it would also be conceivable to move the rack 41 vertically instead.

In einer weiteren Ausführung, die wiederum gemäß Fig. 1-5 die Führungsschiene durchsetzende Kupplungswellen 8 mit diametralen Schlitzen verwendet, in die Stege der Dreh­zapfen eingreifen, könnte die Verschwenkung der Brett­chen 4 durch ein weiteres Zurückziehen der Führungs­schiene in eine entsprechend tiefere Nut 38 bewirkt werden, wenn jede im Rahmen drehbar gelagerte Kupplungs­welle in einem Abschnitt einen unrunden Querschnitt mit Schraubenflächen hohen Steigung aufweist, sodaß die den­selben Querschnitt aufweisende Durchtrittsöffnung im Quersteg 13 der Führungsschiene 3 beim weiteren Zurück­ziehen der Führungsschiene entlang dieses Abschnittes die Verdrehung jeder Kupplungswelle direkt bewirkt.In a further embodiment, which in turn uses coupling shafts 8 with diametrical slots that penetrate the guide rail according to FIGS , if each coupling shaft rotatably mounted in the frame has a non-circular cross-section with helical surfaces with a high pitch in one section, so that the passage opening in the transverse web 13 of the guide rail 3 having the same cross-section directly causes the rotation of each coupling shaft when the guide rail is retracted further along this section.
