Abstract

The slats of a roller shutter having a rolling-up device are guided in two vertical guide rails and mounted rotatably about pivots which protrude on the end face by means of a common swivel drive (7). The latter comprises, per pivot, a toothed wheel (11), a chain (12) which engages jointly with all the toothed wheels (11), and an outer actuating device (30). A drive for adjusting the guide rail between the roller shutter position and the blind position is coupled to the swivel drive (7) in a sequential control. Thus, the swivel drive (7) on the one hand is blocked during the adjustment of the guide rail and in the roller shutter position thereof, and on the other hand the adjusting drive is blocked during the swivelling of the slats. <IMAGE>

Description

Die Erfindung betrifft einen Rolladen mit einer Aufrolleinrichtung, mit an einem Zugorgan aneinandergereihten Brettchen, von denen stirnseitig insbesondere mittig angeordnete Drehzapfen abstehen, die mittels eines gemeinsamen Schwenkantriebs verdrehbar sind, mit zwei vertikalen Führungsschienen, die jeweils zwei parallel zueinander verlaufende Stege aufweisen, und mittels eines Verstellantriebes aus einer Rolladenstellung, in der die Endabschnitte der Brettchen zwischen den Stegen geführt sind, unter Freigabe der Endabschnitte in eine Jalousiestellung verschiebbar sind, in der nur die Drehzapfen der Brettchen geführt sind, und mit einer gemeinsamen äußeren Betätigungseinrichtung für den Verstellantrieb und den Schwenkantrieb.The invention relates to a roller shutter with a roll-up device, with lined up on a traction element, from which protrude in particular centrally located pivots, which can be rotated by means of a common swivel drive, with two vertical guide rails, each having two parallel webs, and by means of one Adjustment drive from a roller shutter position in which the end sections of the boards are guided between the webs, with release of the end sections can be moved into a blind position in which only the pivot pins of the boards are guided, and with a common external actuating device for the adjustment drive and the swivel drive.

Ein derartiger Rolladen ist beispielsweise der EP-A-141 805 zu entnehmen. Der Rolladen enthält einen kombinierten Antrieb für den Wechsel zwischen Rolladen und Jalousie, in dem die mit Schraubenflächen versehenen Drehzapfen während der Verschiebung der Führungsschienen gedreht werden. Die Lösung erscheint zwar konstruktiv einfach, weist aber Nachteile in der Bedienung auf: Die Führungsschiene muß schräg oder im Kreisbogen angehoben werden, wobei das Zugorgan mitverschoben wird, und es ist eine freie Schwenkung der Brettchen in der Jalousiestellung nicht möglich. Weiters kann der Schwenkwinkel nicht größer als 90° sein, da er vom Verschiebeweg des Zugorganes auf den Drehzapfen abhängt. Die Schraubenflächen unterliegen auch einer nicht zu vermeidenden Abnützung, die die Dauerfunktion in Frage stellt.Such a roller shutter can be found, for example, in EP-A-141 805. The roller shutter contains a combined drive for changing between roller shutters and blinds, in which the pivots with screw surfaces are turned during the displacement of the guide rails. Although the solution appears to be structurally simple, it has disadvantages in terms of operation: the guide rail must be lifted at an angle or in a circular arc, with the traction element being moved as well, and free movement of the boards in the blind position is not possible. Furthermore, the swivel angle can not be greater than 90 °, since it depends on the displacement of the traction element on the pivot. The screw surfaces are also subject to unavoidable wear, which questions the permanent function.

Die Erfindung hat es sich nun zur Aufgabe gestellt, einen derartigen Rolladen sowohl in der Rolladenverwendung als auch in der Jalousieverwendung voll funktionsfähig und bedienungsfreundlich auszubilden, wobei auch eine möglichst lange, störungsfreie Lebensdauer erzielt werden soll.The invention has now set itself the task of making such a roller shutter fully functional both in the use of roller shutters and in the use of blinds and user-friendly training, with the longest possible, trouble-free service life.

Erfindungsgemäß wird dies dadurch erreicht, daß der äußeren Betätigungseinrichtung ein entlang eines Verschiebeweges vor- und rückschiebbarer Sperrschieber zugeordnet ist, daß der Verstellantrieb mit einem am Sperrschieber anliegenden Steuerhebel versehen ist, der zu Beginn des Vorschubs vom Sperrschieber verdrängbar und bis zum Ende des Rückschubs durch den Sperrschieber gesperrt ist, und daß der Schwenkantrieb einen im Verschiebeweg des Sperrschiebers liegenden und nach der Verdrängung des Steuerhebels vom Sperrschieber erfaßbaren Mitnehmer aufweist, sodaß der Verstellantrieb nur vor oder nach dem Schwenkantrieb betätigbar ist.According to the invention, this is achieved in that the outer actuating device is assigned a locking slide that can be pushed back and forth along a displacement path, that the adjustment drive is provided with a control lever resting on the locking slide, which can be displaced by the locking slide at the beginning of the feed and until the end of the push-back by Locking slide is locked, and that the swivel drive has a driver lying in the displacement path of the locking slide and after the displacement of the control lever by the locking slide detectable driver, so that the adjustment drive can be actuated only before or after the swivel drive.

Somit wird mittels der gemeinsamen Betätigungseinrichtung eine Folgesteuerung erreicht, die den Schwenkantrieb der Brettchen ausschließlich in der Jalousiestellung der Führungsschiene, und den Verstellantrieb der Führungsschiene ausschließlich in der Rolladenstellung der Brettchen zuläßt.A sequence control is thus achieved by means of the common actuating device, which permits the pivoting drive of the boards only in the blind position of the guide rail and the adjustment drive of the guide rail only in the roller shutter position of the boards.

Durch die wechselweise gegebenen Sperren des Verstellantriebes der Führungsschiene und des Schwenkantriebes der Brettchen läßt sich deren Schwenkwinkel beliebig wählen und einstellen.Due to the alternating locks of the adjustment drive of the guide rail and the swivel drive of the board, their swivel angle can be selected and adjusted as desired.

In einer ersten Ausführung kann dabei vorgesehen sein, daß der Schwenkantrieb pro Drehzapfen ein Zahnrad und eine zum gleichzeitigen Eingriff in alle Zahnräder ausgebildete Verzahnung aufweist. Dabei ist bevorzugt die Verzahnung an einer Kette ausgebildet, an deren erstem Ende eine Rückholfeder angeschlossen und an deren zweitem, parallel umgelenkten Ende der Mitnehmer vorgesehen ist, und als äußere Betätigungseinrichtung ein Seilzug vorgesehen, der in verschiedenen Stellungen festlegbar und mit dem Sperrschieber verbunden ist.In a first embodiment it can be provided that the swivel drive has one gear per pivot and a toothing designed for simultaneous engagement in all the gears. The toothing is preferably formed on a chain, at the first end of which a return spring is connected and on the second, parallel deflected end of the driver, and as an external actuating device Cable provided, which can be fixed in different positions and connected to the gate valve.

In einer weiteren Ausführung ist insbesondere vorgesehen, daß der Sperrschieber von einer mit der Rückholfeder der Kette gleichgerichtet wirksamen Druckfeder beaufschlagt ist. Eine konstruktiv günstige Anordnung ergibt sich dabei dann, wenn der Sperrschieber einen Längsschlitz aufweist, in dem der am zweiten Ende der Kette vorgesehene Mitnehmer verschiebbar geführt ist, wobei sich die Druckfeder zwischen dem Sperrschieber und dem Mitnehmer abstützt.In a further embodiment it is particularly provided that the locking slide is acted upon by a compression spring which acts in the same direction as the return spring of the chain. A structurally advantageous arrangement is obtained when the locking slide has a longitudinal slot in which the driver provided at the second end of the chain is displaceably guided, the compression spring being supported between the locking slide and the driver.

Der Verstellantrieb der Führungsschiene weist bevorzugt zumindest zwei mit Abstand übereinander angeordnete, verschwenkbare Steuernocken auf, die über eine vertikale Zugstange verbunden sind, an der der Steuerhebel angelenkt ist.The adjustment drive of the guide rail preferably has at least two pivotable control cams which are arranged at a distance from one another and are connected via a vertical pull rod to which the control lever is articulated.

Anstelle der vorstehend erwähnten Federn, die jeweils die selbsttätige Rückkehr der einzeln beweglichen Teile in die Ausgangsstellung bewirken, in der die Rolladenstellungen von Führungsschienen und Brettchen vorliegen, kann jeweils auch die Zwangsführung nach beiden Seiten erfolgen, indem beispielsweise als Betätigungseinrichtung ein Kurbeltrieb oder dergleichen, als Verzahnung eine geschlossene Kette, usw. vorgesehen ist.Instead of the springs mentioned above, which each bring about the automatic return of the individually movable parts to the starting position in which the roller shutter positions of guide rails and boards are present, the forced guidance can also take place on both sides, for example by using a crank mechanism or the like as an actuating device Interlocking a closed chain, etc. is provided.

Insbesondere bei einer vollständig verschiebbaren Führungs
schiene oder einer Führungsschiene, deren Stege verschiebbar sind, kann die Verzahnung auch in der Führungsschiene angeordnet sein, wobei deren Überführung in die Jalousiestellung die als Zahnstange ausgebildete Verzahnung in alle Zahnräder eingreifen läßt.
Especially with a fully sliding guide
rail or a guide rail, the webs of which are displaceable, the toothing can also be arranged in the guide rail, its transfer into the blind position allowing the toothing designed as a rack to engage in all the gears.

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, 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 ineinandergreifen.A roller shutter according to the invention has a frame 2, or the like on a window 1. is provided. The frame 2 can be designed as a separate part to be attached to the window frame or already integrated in the frame profile. As can be seen from the drawings, each of the two vertically extending parts of the frame 2 has a groove 38 which extends in the roller shutter plane and which is open towards the boards 4 of the roller shutter. A U-shaped guide rail 3 is arranged in the groove 38, which 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 release the end sections of the boards 4 in the guide rail 3 retracted into the blind position according to FIG. 2, so that these can be pivoted about the pivot pin 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 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 the fully closed position (FIG. 5).

Um nun einerseits in der Rolladenstellung gemäß Fig. 1, die Brettchen 4 in üblicher Weise vollständig auf- und abrollen, beliebige Zwischenstellung 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 unroll the boards 4 in the usual way completely in the roller shutter position according to FIG. 1, to set any intermediate position and to provide air passage gaps 31 (FIG. 5) and on the other hand to twist the boards together from the pivot drive 7 in the blind position to be able, 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 one diametrically at the end of the pivot 5 trained flat web 10 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 hier für aus einzeln aneinandergelenkten Laschen 18 zusammen, wobei jede Lasche 18 einseitig ein Langloch 19 aufweist, sodaß für den Gelenksbolzen 20 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 lie 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 traction element 6 is composed here 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 20, which corresponds to the width of the air passage gap 31, the center distance of the coupling shafts 8 being the board height including 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. 3 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. The pivoted position of the control cams 14 is shown in broken lines in FIGS. 3 and 4, the guide rail 3 being pushed back under the action of a plurality of compression springs 32 and occupying the position shown in FIG. 3.

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 unten verschiebt und die Steuernocken 14 aufwärts verschwenkt. Diese drücken die Führungsschiene 3 nach vorne, sodaß die Endabschnitte der Brettchen 4 eingefaßt sind, und die nicht gezeigte Aufrolleinrichtung einsetzbar ist.For the return to the roller shutter use, the cable pull 30 is released and the return spring 22 swivels 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, which moves the lifting rod 17 downwards and pivots the control cams 14 upwards. These press 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 used.

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 in der Rolladenstellung gemäß Fig.6 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 is therefore displaceable with the guide rail 3, so that it is out of engagement with the gear wheels 40 in the roller shutter position according to FIG. 6 and in engagement with the gear wheels 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 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 hoher 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 through the guide rail, as shown in FIGS. 1-5, engage in the webs of the pivots, the pivoting of the tabs 4 could be brought about by a further pulling back of the guide rail into a correspondingly deeper groove 38 , if each coupling shaft rotatably mounted in the frame has a non-circular cross section with screw surfaces of high pitch in one section, so that the passage opening having the same cross section in the transverse web 13 of the guide rail 3 during further retraction the guide rail along this section causes the rotation of each coupling shaft directly.
