Description

Die Erfindung betrifft einen Rolladen mit einem Behang aus horizontalen Lamellen, die an ihren Stirnseiten : mittels horizontaler Zapfen an Zugorganen aufgehängt sind, in vertikalen Führungsschienen zwischen einer oberen und unteren Endlage geführt, und ab einer vorgegebenen oberen Lamelle um die Zapfen schwenkbar sind, wobei die schwenkbaren Lamellen mittels Wendeorganen miteinander verbunden sind, mit in gleicher Höhe in den Führungsschienen angebrachten Steuerbacken, die mit stirnseitigen Wendestiften an der obersten schwenkbaren Lamelle in Eingriff bringbar sind und die schwenkbaren Lamellen vor Erreichen einer unteren Endlage in eine Jalousiestellung ausschwenken, und nach Verlassen der Steuerbacken in die Rolladenstellung zurückschwenken.The invention relates to a roller shutter with a curtain made of horizontal slats, which are hung on their end faces: by means of horizontal pins on traction elements, guided in vertical guide rails between an upper and lower end position, and can be pivoted about the pins from a predetermined upper slat, the pivotable slats are connected to each other by means of turning organs, with control jaws mounted at the same height in the guide rails, which can be brought into engagement with end turning pins on the top pivotable slat and pivot the pivoting slats into a blind position before reaching a lower end position, and after leaving the control jaws swing back into the shutter position.

Bei dem Rolladen gemäß der älteren deutschen Patentanmeldung P 29 29 675.1-25 sind die Wendebänder an den stirnseitigen Enden des Behangs angebracht, so daß die Wendebänder den freien Durchblick durch die ausgeschwenkten Lamellen nicht behindern. Die Wendebänder laufen verdeckt in den vertikalen Führungsschienen und beeinträchtigen dort den ästhetischen Gesamteindruck des Rolladens nicht. Die Wendeorgane lassen sich nur deshalb in die seitlichen Führungsschienen hineinverlegen, da an den Stirnwänden der Lamellen die Zugorgane und die Wendeorgane in Lamellenlängsrichtung gegeneinander versetzt sind, so daß beim Aufwickeln des Behangs auf der Wickel-Trommel sich die Zugorgane neben den Wendeorganen aufwickeln. Es bilden sich also nebeneinander auf der Wickel-Trommel zwei Wickel, ein Wickel aus Zugorganen einschließlich der Lamellen-Zapfen, und ein weiterer Wickel aus Wendeorganen einschließlich der entsprechenden Lagerstifte für diese Organe.In the roller shutter according to the older German patent application P 29 29 675.1-25, the turning tapes are attached to the front ends of the curtain, so that the turning tapes do not impede the clear view through the swung-out slats. The turning tapes run concealed in the vertical guide rails and do not impair the overall aesthetic impression of the roller shutter. Leave the turning organs the only reason why inlaying in the lateral guide rails, since at the end walls of the blades which tension elements and the turning members are offset in the lamella longitudinal direction against each other so that when winding the B ehangs on the winding drum, the traction elements adjacent to the turning bodies wound. Two coils are formed next to each other on the winding drum, a winding made of traction elements including the lamella cones, and a further winding consisting of turning elements including the corresponding bearing pins for these elements.

Es hat sich gezeigt, daß ein störungsfreies Funktionieren des Rolladens gemäß der P 29 29 675.1-25 erst dann möglich ist, wenn die Zugorgane und deren an den Lamellen befestigten Zapfen sowie die Wendeorgane und deren an den Lamellen befestigten Befestigungsstifte etwa auf derselben Wickelspirale liegen können, wenn der Behang des Rolladens auf der Wickel-Trommel aufgewickelt wird. Erst dadurch ist sichergestellt, daß sich die Lamellen an die Wickeltrommel anlegen und nicht durch unerwünschte Spannungen in den Zug- oder Wendeorganen teilweise von der Wickeltrommel abstehen.It has been shown that trouble-free functioning of the roller shutter according to P 29 29 675.1-25 is only possible if the pulling elements and their pins attached to the slats as well as the turning elements and their fixing pins attached to the slats can lie approximately on the same winding spiral when the curtain of the roller shutter is wound up on the winding drum. This is the only way to ensure that the lamellae rest on the winding drum and do not partially protrude from the winding drum due to undesirable tensions in the pulling or turning elements.

Aufgabe der vorlieqenden Erfindung ist es daher, den Rolladen der eingangs genannten Art derart zu verbessern, daß ein störungsfreies und stets zuverlässiqes Funktonieren des Rolladens möglich ist.The object of the vorlie q end the invention is therefore to improve the shutters of the type mentioned so that a trouble-free and always zuverlässiqes capabilities are of the rolling shutter is possible.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß an dem stirnseitigen Zapfen der schwenkbaren Lamelle je ein Winkelhebel befestigt ist und einen ersten Schenkel parallel zur Stirnwand der Lamelle, und einen zweiten Schenkel der Winkelhebel an beiden Stirnseiten des Behangs gelenkig hält, daß der erste Schenkel des Winkehlebels innerhalb der Projetion der Querschnittkontur der Lamelle liegt, daß das Zugorgan und das Wendeorgan in Lamellen-Längsrichtung einen vorgegebenen Abstand besitzen, und daß der zweite Schenkel des Winkelhebels und der Zapfen von der innenliegenden Auflageebene der Lamelle etwa denselben Abstand besitzen.This object is achieved in that an angle lever is attached to each of the front pins of the pivotable slat and a first leg parallel to the end wall of the slat, and a second leg of the angle lever on both ends of the curtain keeps articulated, that the first leg of the angle lever lies within the projection of the cross-sectional contour of the lamella, that the pulling element and the turning element have a predetermined distance in the longitudinal direction of the lamellae, and that the second leg of the angle lever and the pin are from the inner support plane of the Slats have approximately the same distance.

Die stirnseitigen Winkelhebel liegen innerhalb der Projektion der Umfangskontur der Lamellen bzw. besitzen eine mit der Umfangskontur der Lamellen fluchtende Gestalt. Der an den Lamellen befestigte horizontale Zapfen, an dem die Lamellen in Lagerbuchsen des Zugorgans aufgehängt sind, sowie der zweite Schenkel des Winkelhebels, an dem die Lamellen schwenkbar in Lagerbuchsen der Wendeorgane gelagert sind, besitzen erfindungsgemäß denselben Abstand von der Auflageebene, in der sich die betreffende Lamelle beim Aufwickeln auf die Wickeltrommel gegen darunterliegende Lamellen abstützt. Werden die Lamellen auf die Wickeltrommel aufgewickelt, so liegen die freien Enden der Zapfen und die zweitePSchenkel. annähernd auf derselben Spirale, und die Lamellen liegen ebenfalls im wesentlichen in der Wickelspirale. Das unerwünschte Aufstellen der Lamellen auf der Wickeltrommel wird sicher verhindert.The end-side angle levers lie within the projection of the circumferential contour of the slats or have a shape that is flush with the circumferential contour of the slats. The horizontal pin attached to the slats, on which the slats are suspended in bearing bushes of the pulling element, and the second leg of the angle lever, on which the slats are pivotally mounted in bearing bushes of the turning elements, have the same distance from the support plane in which the supports the slat in question when winding it onto the winding drum against the slats underneath. If the lamellae are wound onto the winding drum, the free ends of the pins and the second P-legs lie. approximately on the same spiral, and the lamellae also lie essentially in the winding spiral. The undesired positioning of the slats on the winding drum is reliably prevented.

Würde dagegen der zweite Schenkel des Winkelhebels einen wesentlich größeren Abstand von der genannten Auflageebene besitzen als die Zapfen für die Zugorgane, so greifen.an den einzelnen, auf der Wickeltrommel aufgewickelten Lamellen unerwünschte Drehmomente an, die dazu führen, daß sich die Lamellen "aufstellen", d. h. daß die Unterkante der Lamelle von dem Lamellen-Wickel abhebt, weil die Wendeorgane - bei gleicher Länge wie die Zugorgane - auf einer größeren Wickelspirale zwangsgewickelt sind. Besitzt dagegen der zweite Schenkel des Winkelhebels, an dem die Wendeorgange befestigt sind, einen kleineren Abstand von der genannten Auflageebene als die Zapfen zur Befestigung der Zugorgane, so werden die Zugorgane auf der Wickeltrommel in einer größeren Spirale geführt als die Wendeorgane. Die Wendeorgane ziehen dann die untere Kante der Lamellen mit großer Kraft gegen den Lamellen-Wickel, sodurch die obere Kante der Lamellen vom Lamellen-Wickel abheben und aufstellen kann.If, on the other hand, the second leg of the bell crank would have a much greater distance from the support plane than the pins for the traction elements, then undesired torques act on the individual lamellae wound on the winding drum, which lead to the lamellae "erecting" , that is, the lower edge of the slat from the slat winding takes off because the turning elements - with the same length as the pulling elements - are forcibly wound on a larger winding spiral. Has, however, the second leg of the angle lever on which the Wendeorgange are attached, a smaller distance from said supporting plane than the stud for mounting the traction means, the traction elements are guided on the winding drum in a larger spiral than the W organs. The turning organs then pull the lower edge of the slats against the slat winding with great force, so that the upper edge of the slats can lift off and lift up from the slat winding.

Bevorzugt besitzt der erste Schenkel des Winkelhebels senkrecht zur Lamellen-Längsrichtung eine etwa dem Lamellen-Querschnitt entsprechende Form._Der Winkelhebel stützt sich dann in derselben Auflageebene ab wie die Lamelle, wenn die Lamellen auf die Wickel- trommel aufgewickelt werden. Es wird dann verhindert, daß eventuell vorhandene restliche Zugkräfte in den Zugorganen und Wendeorganen über den Winkelhebel ein Torsionsmomentauf die Lamellen übertragen und diese dadurch verformen.Preferably, the first leg of the angle lever perpendicular to the longitudinal direction of the slats has a shape approximately corresponding to the slat cross-section. The angle lever is then supported in the same support plane as the slat when the slats are wound onto the winding drum. It is then prevented that any remaining tensile forces in the tension elements and turning elements transmit a torsional moment to the slats via the angle lever and thereby deform them.

Bevorzugt ist der Zapfen über den Winkel hinaus horizontal verlängert und lagert mit seinem freien Ende in einer Lagerbuchse des Zugorgans. Die Lagerbuchsen des Zugorgans besitzen voneinander denselben Abstand wie die entsprechenden Lagerbuchsen der Wendeorgane. Die Wendeorgane liegen bevorzugt noch weiter außen als die Zugorgane. Die vertikalen Führungsschienen besitzen in der Regel eine zwischen Stirnwand der Lamelle und Winkelhebel nach innen gerichtete Seitenwand, die die Winkelhebel abdeckt und eine vorgegebene Spaltbreite vor der Rückwand der Führungs- schiene endet. Im Spalt zwischen dieser Seitenwand und der Rückwand wird ein bevorzugt verdickter Bereich des Zapfens geführt.The pin is preferably horizontally extended beyond the angle and is supported with its free end in a bearing bush of the pulling element. The bearing bushes of the pulling element are at the same distance from each other as the corresponding bearing bushes of the turning elements. The turning elements are preferably further out than the pulling elements. The vertical guide rails have ends DC busbar between the end wall of the slat and angle levers inwardly directed side wall that covers the angle lever and un a predetermined gap width in front of the rear wall of the lead-in rule. A preferably thickened area of the pin is guided in the gap between this side wall and the rear wall.

Die Lamellen besitzen bevorzugt an beiden Stirnseiten ein offenes Hohlprofil. Bevorzugt sind die Zapfen und die Winkelhebel an Endkappen angebracht, welche die Stirnwand der Lamellen bilden und in dem Hohlprofil verankerbar sind. Diese Ausführungsform besitzt den Vorteil einer einfachen und raschen Montierbarkeit unterschiedlicher Behangbreiten. Bevorzugt besteht die Endkappe einschließlich der abdeckenden Stirnwand für die Lamelle sowie der Zapfenabschnitt zwischen Stirnwand und Winkelhebel sowie der Winkelhebel aus Kunststoffmaterial. Das freie Ende des Zapfens sowie der zweite Schenkel des Winkelhebels bestehen bevorzugt aus einem Metallstift gleichen Durchmessers, die in das Kunststoff-Formteil eingepreßt sind.The slats preferably have an open hollow profile on both ends. The pins and the angle levers are preferably attached to end caps which form the end wall of the slats and can be anchored in the hollow profile. This embodiment has the advantage of simple and quick installation of different curtain widths. The end cap, including the covering end wall for the lamella and the pin section between the end wall and the angle lever and the angle lever, are preferably made of plastic material. The free end of the pin and the second leg of the angle lever preferably consist of a metal pin of the same diameter, which are pressed into the plastic molding.

B. einstückig - ein Winkelhebel 24, 25 an, dessen erster Schenkel 24 im Abstand des Zwischenabschnitts 16' des Zapfens 16 parallel zur Stirnwand 9 der Lamelle 4 verläuft, und dessen zweiter Schenkel 25 in vorgegebenem Abstand vom Zapfen 16 - bevorzugt in der Nähe der unteren Horizontalkante der Lamelle.4 - senkrecht zum ersten Schenkel 24 und parallel zum Zapfen 16 in Lamellen-Längsrichtung verläuft. Der zweite Schenkel 25 geht an seinem freien Ende in einen Stift über, der freie Endabschnitt 16" des Zapfens 16 ist ebenfalls als ein Stift ausgebildet, dessen Durchmesser dem Endstift des zweiten Schenkels 25 entspricht.The end caps 80 of the lamellae 4 have a front end 9 which covers the hollow profile of the lamellae 4, and a pin 16, which has an intermediate section 16 'and a free end section 16'', approximately as an extension of the upper horizontal edge of the lamella. the pin is followed - for example in one piece - by an angle lever 24, 25, the first leg 24 of which runs parallel to the end wall 9 of the lamella 4 at a distance from the intermediate section 16 'of the pin 16, and whose second leg 25 is at a predetermined distance from the pin 16 - preferably in the vicinity of the lower horizontal edge of the lamella. 4 - runs perpendicular to the first leg 24 and parallel to the pin 16 in the longitudinal direction of the lamella. The second leg 25 merges into a pin at its free end, the free end section 16 "of the Pin 16 is also designed as a pin, the through knife corresponds to the end pin of the second leg 25.

Die Endabschnitte 16" der Zapfen 16 sind in den Lagerbuchsen 22 der Zugorgane 20 gelagert. Der Endabschnitt 25" des zweiten Schenkels 25 des Winkelhebels 24, 25 ist in den Lagerbuchsen 30 der Wendeorgane 28 schwenkbar gelagert.Am Winkelhebel 24, 25 der obersten schwenkbaren Lamelle 4 befindet sich ein Wendestift, der von Steuerbacken 40 innerhalb der seitlichen Führungsschienen ausgesteuert wird. Wird z. B. die Abwärtsbewegung des Wendestifts während einer Abwärtsbewegung des Behangs durch die Steuerbacken retardiert oder angehalten, so werden dadurch die schwenkbaren Lamellen über die Wendeorgane 28 in ihre Jalousiestellung geschwenkt.Wird der Wendestift aus dieser Jalousiestellung freigegeben, so gehen die schwenkbaren Lamellen - unter ihrem Eigengewicht - in die Rolladenstellung zurück.The end sections 16 "of the pins 16 are mounted in the bearing bushes 22 of the pulling elements 20. The end section 25" of the second leg 25 of the angle lever 24, 25 is pivotally mounted in the bearing bushes 30 of the turning elements 28. On the angle lever 24, 25 of the uppermost pivotable slat 4 there is a turning pin which is actuated by control jaws 40 within the lateral guide rails. Is z. If, for example, the downward movement of the turning pin is retarded or stopped by the control jaws during a downward movement of the curtain, the pivotable slats are pivoted into their blind position via the turning elements 28. If the turning pin is released from this blind position, the pivotable slats move - under their own weight - back to the shutter position.

Fig. 2 zeigt einen Querschnitt durch eine seitliche Führungsschiene 50 mit einer Aufsicht auf die Führungsorgane sowie ein Zugorgan 20 und ein Wendeorgan 28. Die Führungsschiene 50 besitzt etwa rechteckförmiges Profil, wobei einer der Stirnwand 9 der Lamelle 4 benachbarte Seitenwand einen Spalt 52 mit der Rückwand 54 der Führungsschiene bildet. In diesem Spalt 52 der Führungsschiene 50. wird der Zwischenabschnitt 16' geführt, der Winkelhebel 24, 25 liegt innerhalb der Führungsschiene 50. Der Endabschnitt 16" des Zapfens 16 ist in den Lagerbuchsen 22 des Zugorgans 20 gelagert, der Endabschnitt 25" des zweiten Schenkels 25 des Winkelhebels 24, 25 wird in einer entsprechenden Lagerbuchse 30 am Wendeorgan 28 entsprechend gelagert. Der Zwischenabschnitt 25' des zweiten Schenkels 25 bildet bei der obersten schwenkbaren Lamelle den Wendestift, der gegen einen Steuerbacken 40 läuft (nur schematisch dargestellt). In Lamellen-Längsrichtung ist das Zugorgan 20 vom Wendeorgan 28 ausreichend beabstandet, so daß Zugorgan 20 und Wendeorgan 28 beim Aufwickeln auf die Wickeltrommel 90 zwei ausreichend beabstandete Wickelspiralen bilden (vgl. Fig. 4).2 shows a cross section through a lateral guide rail 50 with a view of the guide members as well as a pulling member 20 and a turning member 28. The guide rail 50 has an approximately rectangular profile, one side wall adjacent to the end wall 9 of the lamella 4 having a gap 52 with the rear wall 54 of the guide rail forms. The intermediate section 16 ′ is guided in this gap 52 of the guide rail 50. The angle lever 24, 25 lies within the guide rail 50. The end section 16 ″ of the pin 16 is mounted in the bearing bushes 22 of the pulling member 20, the end section 25 ″ of the second leg 25 of the angle lever 24, 25 is mounted accordingly in a corresponding bearing bush 30 on the turning element 28. The Intermediate section 25 'of the second leg 25 forms the turning pin in the uppermost pivotable lamella, which runs against a control jaw 40 (only shown schematically). In the longitudinal direction of the slats, the pulling element 20 is sufficiently spaced from the turning element 28 so that the pulling element 20 and the turning element 28 form two sufficiently spaced winding spirals when they are wound onto the winding drum 90 (cf. FIG. 4).

Fig. 3 zeigt eine Aufsicht auf die Stirnseite einer Lamelle 4 mit aufgesetzter Endkappe 80. Dargestellt ist der Endabschnitt 16" des Zapfens 16 sowie der erste Schenkel 24 und der zweite Schenkel 25 des Winkelhebels. Der zweite Schenkel 25 des Winkelhebels geht über einen Zwischenabschnitt 25' in einen Endabschnitt 25" über, der denselben Durchmesser besitzt wie der Endabschnitt 16" des Zapfens 16. Der erste Schenkel 24 des Winkelhebels besitzt senkrecht zur Lamellen-Längsrichtung eine Form, die sich weitgehend mit dem Lamellen-Querschnitt deckt, so daß der erste Schenkel 24 innerhalb bzw. fluchtend mit der Projektion der Querschnittkontur der Lamelle 4 verläuft. Die Lamelle 4 berührt mit ihrer Oberfläche, welche in aufgehängtem oder aufgewickeltem Zustand des Behangs innen liegt, eine "innenliegende Auflageebene". Die Berührung der Auflageebene erfolgt beim dargestellten Lamellenquerschnitt an der innenliegenden unteren Horizontalkante 5 und an einer weiteren innenliegenden Horizontalkante 6 zwischen der unteren Horizontalkante 5 und der oberen Horizontalkante 7.3 shows a top view of the end face of a lamella 4 with an attached end cap 80. The end section 16 ″ of the pin 16 and the first leg 24 and the second leg 25 of the angle lever are shown. The second leg 25 of the angle lever extends over an intermediate section 25 'in an end portion 25 ", which has the same diameter as the end portion 16" of the pin 16. The first leg 24 of the bell crank has a shape perpendicular to the longitudinal direction of the slats, which largely coincides with the slat cross-section, so that the first Leg 24 runs within or in alignment with the projection of the cross-sectional contour of the lamella 4. The lamella 4, with its surface, which lies inside when the curtain is in the suspended or wound state, touches an “inner support plane.” The contact with the support plane takes place in the slat cross section shown the inner lower horizontal edge 5 and another inner horizontal edge 6 between the lower horizontal edge 5 and the upper horizontal edge 7.

Der zweite Schenkel 25 des Winkelhebels 24, 25, insbesondere jedoch der Endabschnitt 25" des zweiten Schenkels 25 sowie der Endabschnitt 16" des Zapfens 16 besitzen von der durch die Kanten 5 und 6 aufgespannten Auflageebene denselben Abstand. Eine durch die Mittelpunkte der Endabschnitte 16" und 25" gelegte Ebene verläuft somit zur Auflageebene parallel. Durch dieses Merkmal ist sichergestellt, daß die Endabschnitte 16" für die Zugorgane sowie die Endabschnitte 25" für die Wendeorgane auf etwa derselben Wickelspirale liegen, wenn der Behang auf die Wickel- trommel 90 aufgewickelt wird, vgl. Fig. 4.The second leg 25 of the angle lever 24, 25, but in particular the end section 25 "of the second Leg 25 and the end section 16 "of the pin 16 are at the same distance from the support plane spanned by the edges 5 and 6. A plane through the centers of the end sections 16" and 25 "thus runs parallel to the support plane. This feature ensures that the end sections 16 ″ for the traction members and the end sections 25 ″ for the turning members lie on approximately the same winding spiral when the curtain is wound onto the winding drum 90, cf. FIG. 4.

Es ist dadurch sichergestellt, daß sich sowohl die Wendeorgane als auch die Zugorgane beim Aufwickeln auf die Wickeltrommel 90 gleichermaßen entlasten, daß also weder in den Zugorganen 20 noch in den Wendeorganen 28 Zugkräfte verbleiben bzw. entstehen, welche die Lamellen auf der Wickeltrommel aus der entlastenden Position herausdrängen, in der sich die Lamellen dann befinden, wenn ihre Auflage an den vorgegebenen Auflagekanten 5, 6 erfolgt.It is thereby ensured that both the turning members and the pulling members are equally relieved when they are wound onto the winding drum 90, that is to say that neither tensile forces remain in the pulling members 20 nor in the turning members 28, which force the slats on the winding drum from the relieving load Push out the position in which the slats are when they rest on the specified contact edges 5, 6.
