Description

Die Erfindung betrifft einen Rollladen insbesondere für Schrägfenster, mit einer Wickelwelle in einem Gehäuse, das beidseits rechtwinklig abstehend angeordnete Führungsarme aufweist, deren freie Enden mit einem Querriegel verbunden sind, sowie mit einem auf die Wickelwelle auf- und von dieser abwickelbaren Rollladenpanzer oder Beschattungsbehang ohne oder mit nur geringer Eigensteifigkeit, dessen freies Ende eine Endleiste mit beidseits überstehenden, jeweils in Laufnuten der Führungsarme geführten Enden aufweist, von denen zumindest eines mit einem Zugglied verbunden ist, das in einem an der Laufnut vorgesehenen Führungskanal geführt ist, wobei die Wickelwelle von einem Hand- oder Motorantrieb antreibbar, das Aus- und Einfahren des Rollladenpanzers oder Rollobehanges bewirkt. The invention relates to a roller shutter, in particular for diagonal windows, with a winding shaft in a housing, the right angles on both sides having spaced guide arms, the free ends are connected to a crossbar, as well as with a on the winding shaft on and from this unwindable roller shutter or shading without or with only little rigidity, whose free end an end bar with on both sides protruding, each in Running grooves of the guide arms has guided ends, of which at least one is connected to a tension member which in a at the Running groove provided guide channel is guided, wherein the winding shaft drivable by a manual or motor drive, the off and Retraction of the roller shutter shell or Rollobehanges effected.

Fenster werden zur Abdunkelung oder zur Abschattung eines Raumes mit Rollläden versehen, wobei vor dem Fenster ein auf eine Wickelwelle aufwickel- und von dieser abwickelbarer Rollladenpanzer vorgesehen ist, der aus vorteilhaft durch Gewebe verbundenen Stäben oder von einem Rollobehang gebildet ist. Bei Schräg-Fenstern, wie z.B. bei Dachflächenfenstern, bei Wintergärten o.dgl. müssen derartige Rollläden in schräger Lage angebracht werden, um Sichtschutz oder Beschattungen zu erreichen. Besonders bei relativ flach liegenden Dächern reicht dann die Steigung der Schräg- oder Dachflächenfenster nicht aus, um den Rollladenpanzer oder Rollobehang durch den von der Endleiste mit (relativ) geringen Masse ausgeübten Zug so unter Spannung zu halten, dass ein Abwickeln erfolgen kann.Windows are used to darken or shade a room provided with shutters, wherein in front of the window on a winding shaft wind up and from this unwindable roller shutter is provided, consisting of advantageously connected by tissue rods or is formed by a Rollobehang. For slanted windows, such as. in roof windows, conservatories or the like. have to such shutters are mounted in an inclined position to privacy or shading. Especially at relative flat roofs then extends the slope of the oblique or Roof window does not go out to the roller shutter or Rollobehang through from the end bar with (relatively) low mass Exercise train so keep under tension that unwinding can be done.

Aus der DE 20 002 359 U ist ein Rollladen gemäß dem Oberbegriff des Anspruchs 1 bekannt, dessen Behang ohne wesentliche Eigensteifigkeit zur Beschattung für Fenster, insbesondere für Schrägfenster einsetzbar ist. Die Wickelwelle ist in einem Gehäuse angeordnet, an das rechtwinklig abstehende Führungsarme mit Laufnuten angesetzt sind, in denen die Endleisten des Rollobehanges geführt sind. Im Bereich zumindest einer dieser Laufnuten ist ein flexibles Zugglied vorgesehen, das mit dem zugeordneten Ende der Endleiste verbunden und um eine auf das mit dem Führungskanal korrespondierenden Ende der Wickelwelle aufgesetzte Antriebsscheibe geführt ist. Zum Aus- wie auch zum Einfahren des Beschattungsbehanges sind Antriebsmittel vorgesehen, etwa als Handantrieb oder als Motorantrieb, die die Bewegung des Rollo- bzw. Beschattungsbehanges bewirken. Um eine RelativBewegung der Antriebsscheibe gegenüber der Wickelwelle wegen des sich verändernden Durchmessers der Wickelwelle mit auf- bzw. abgewickeltem Behang abzuwenden, muss zwischen Antriebsachse und Wickelwelle ein Ausgleichslager vorgesehen werden. Bei einer ersten Ausführungsform danach ist als Zugglied ein endlos-umlaufendes Glied vorgesehen. Vorlauf- und Rücklauf-Trum dieses Gliedes sind in zwei Führungskanälen geführt, die parallel zueinander verlaufend, miteinander verbunden sind. Für die Bewegung des Rollobehanges wirken das Zugglied und die Antriebsscheibe reibschlüssig zusammen, wobei das Zugglied als das Antriebsrad umschlingendes Endlos-Band oder -schnur vorgesehen ist, das/ die sich in eine umlaufende Umfangsnut oder -rinne einlegt. Bei einer zweiten Ausführungsform ist als Zugglied ein offenes flexibles Glied vorgesehen, dessen freies in den zweiten Führungskanal einläuft. Um Schub- und Zugkräfte übertragen zu können, muss ein Ausbauchen verhindert werden; dazu ist das offene Glied entsprechend steif auszubilden oder so zu führen, dass dieses Ausbauchen unterbunden ist. Dies wird zum einen durch eine sich unter Druck versteifende Kette erreicht, und zum anderen durch eine formschlüssige Führung der Trums des Zuggliedes in einem ersten bzw. einem zweiten Führungskanal, was deren Ausbauchen verhindert. Diesen Lösungen liegen aufwendige Konstruktionen zugrunde, beide erfordern erhöhten Fertigungsaufwand.From DE 20 002 359 U a roller shutter according to the preamble of claim 1 is known whose hangings without significant rigidity for shading windows, can be used in particular for diagonal windows. The winding shaft is arranged in a housing to which projecting at right angles Guide arms are fitted with grooves, in which the end strips the Rollobehanges are guided. In the area of at least one These grooves a flexible tension member is provided with the connected to the associated end of the end bar and one on the with the guide channel corresponding end of the winding shaft attached drive pulley is guided. For the as well as the Retracting the shading device, drive means are provided, as a hand drive or as a motor drive that controls the movement cause the blind or shading curtain. To a relative movement the drive pulley relative to the winding shaft because of changing diameter of the winding shaft with up or unwound To avert hangings, must be between the drive axle and Winding a compensating bearing can be provided. At a first Embodiment thereafter is a tension member is an endless-revolving Limb provided. Flow and return run of this member are guided in two guide channels, which are parallel to each other running, interconnected. For the movement of the roller blind the tension member and the drive pulley act frictionally together, wherein the tension member as the drive wheel encircling Endless tape or cord is provided, the / engages in a circumferential circumferential groove or gutter. At a second embodiment is as a tension member an open flexible Provided member whose free enters the second guide channel. In order to transfer thrust and tensile forces, must be Bulging can be prevented; the open link is corresponding to this form stiff or lead so that this bulging is prevented. This is partly due to a pressure stiffening chain reached, and on the other by a form-fitting Guiding the strands of the tension member in a first or a second guide channel, which prevents their bulging. These solutions are based on complex designs, both require increased manufacturing costs.

Daraus ergibt sich die Aufgabenstellung, einen gattungsgemäßen Rollladen so weiter zu bilden, dass ein derartiger Rollladen in einfacherer Konstruktion wirtschaftlicher herstellbar ist und auch mit nicht oder nur wenig eigensteifen Rollladenpanzern oder Rollobehängen einsetzbar und so auch sicher handhabbar ist.This results in the task, a generic Roller shutters continue to form so that such a shutter in simpler construction is more economical to produce and even with little or no own rigid roller shutter or Rollob hanging used and so safe to handle.

Diese Aufgabenstellung wird nun nach der Erfindung durch die im Hauptanspruch definierten Merkmale gelöst; vorteilhafte Weiterbildungen und bevorzugte Ausführungsformen beschreiben die Unteransprüche.This task is now according to the invention by the im Main claim defined features solved; advantageous developments and preferred embodiments describe the subclaims.

Die Konstruktion geht aus von einem Rollladen mit offenem Zugglied, das mit einem seiner Enden am überstehenden Ende des Endstabes angeschlagen ist. Dieses Zugglied ist in einem neben der Laufnut angeordneten ersten Führungskanal geführt. Ein neben dem ersten Führungskanal angeordneter zweiter Führungskanal nimmt das freie Ende dieses Zuggliedes auf, das endständig rahmenfest etwa nahe der Wickelwelle fest angeschlagen ist. Um den Rollladenpanzer oder den Rollobehang zu bewegen, ist dieser an die Wickelwelle angeschlagen; diese wird mittels eines Antriebsgliedes oder auch direkt etwa mit einem Rohrmotor angetrieben, so dass der Antrieb indirekt oder direkt auf den Rollladenpanzer oder den Rollobehang wirkt, wodurch das bei den Ausführungsformen nach dem Stand der Technik notwendige Ausgleichslager überflüssig wird.The construction is based on a roller shutter with an open tension member, with one of its ends at the protruding end of the end bar is struck. This tension member is in a next to the Run groove arranged first guide channel. One beside the first guide channel arranged second guide channel takes that free end of this tension member, the terminal frame-fixed about is firmly struck near the winding shaft. To the roller shutter tank or to move the Rollobehang, this is to the winding shaft chipped; this is by means of a drive member or also driven directly about with a tubular motor, so the drive indirectly or directly on the roller shutter shell or the Rollobehang acts, which in the embodiments according to the The prior art necessary compensating bearing is unnecessary.

Mindestens ein Auslegearm weist im Bereich einer der Laufnuten einen Führungskanal auf, in dem das flexible Zugglied angeordnet ist, das als elastisches Glied ausgebildet, dehnbar ist und einen Kraftspeicher darstellt. Ein Ende dieses Zuggliedes ist mit der Endleiste verbunden, während das andere Ende rahmenfest so angeschlagen ist, dass dieses Zugglied bei aufgewickeltem Rollladenpanzer oder Behang gespannt ist, so dass dieser bzw. diese mit dieser Spannung abgewickelt werden kann. Um diesen so ausgebildeten Rollladen zu betätigen, wird als Antriebsglied lediglich eine Schnur, eine Kordel, ein Gurtband o.dgl. benötigt, das sowohl von Hand als auch motorisch betätigt werden kann. Dieser Antriebszug ist auf eine zumindest einseitig an die Wickelwelle angesetzte Wickeltrommel aufgespult. Alternativ kann als Antriebsglied auch eine mit einem Antriebsmotor versehene Wickelwelle vorgesehen werden.At least one extension arm has in the region of one of the grooves Guide channel, in which the flexible tension member is arranged, the designed as an elastic member, is stretchable and an energy storage represents. One end of this tension member is connected to the end bar, while the other end is framed so firmly that stretched this tension member with wound roller shutter or curtain is, so that this or this settled with this tension can be. To operate this so-formed shutter, is as a drive member only a cord, a cord, a webbing or the like. required, which are operated both by hand and by motor can. This drive train is on at least one side of the Winding shaft attached winding drum wound up. Alternatively, as Drive member also provided with a drive motor winding shaft be provided.

Als elastisch-flexibles Zugglied ist ein dehnbares Glied vorgesehen, beispielsweise eine 'Schraubenfeder, ein Gummiseil o.dgl. Das eine Ende dieses elastisch-flexiblen Zuggliedes ist als wirkendes Ende mit der Endleiste verbunden, das freie Ende ist rahmenfest abgestützt. So angeordnet ist dieses elastisch-flexible Zugglied beim Aufwickeln des Rollladenpanzers oder des Rollobehanges des Rollladens gespannt und steht als Kraftspeicher zur Verfügung, der das Abwickeln des Rollobehanges von der Wickelwelle bewirkt, wenn das Antriebsglied nachgelassen wird und die dafür die notwendige Lose gibt. Vorteilhaft ist das andere Ende des elastisch-flexiblen Zuggliedes nahe dem wickelwellenseitigen Ende des Auslegearms angeschlagen, wodurch eine hinreichende Spannlänge verfügbar wird. Um diesen Anschlagpunkt zu erreichen wird dieses elastisch-flexiblen Zugglied über eine im Bereich des der Wickelwelle abgewandten Endes des Rahmens angeordnete Umlenkrolle so geführt, so dass das elastisch-flexible Zugglied beim Einfahren des Rollladenpanzers oder des Rollobehanges gespannt und diese Spannung das Ausfahren des Rollladenpanzers oder des Rollobehanges ermöglicht. As an elastic-flexible tension member, a stretchable member is provided, For example, a 'coil spring, a rubber cord or the like. The one end of this elastically flexible tension member is acting End connected to the end bar, the free end is frame-fixed supported. Arranged is this elastic-flexible tension member when winding the roller shutter or the Rollobehanges the Taut store and is available as a power storage, the the unwinding of the Rollobehanges of the winding shaft causes, if the drive member is released and the necessary Lots there. Advantageously, the other end of the elastic-flexible Tension member struck near the winding shaft end of the extension arm, whereby a sufficient clamping length becomes available. In order to reach this attachment point, this elastic-flexible Tension member over a remote in the region of the winding shaft End of the frame arranged guide roller so guided, so that the elastic-flexible tension member when retracting the roller shutter or the Rollobehanges cocked and this tension the extension the roller shutter shell or Rollobehanges allows.

Diese Einsätze werden vorteilhaft als Kunststoffeinsätze ausgebildet, die für Leichtgängigkeit sorgen. Im Bereich des Endes der Führungsarme ist das Antriebsglied über eine Umlenkrolle geführt, die das elastisch-flexible Zugglied leichtgängig und geräuscharm umlenkt. Ein Hängenbleiben des elastisch-flexiblem Zugglied ist dadurch unterbunden. Diese Umlenkrolle wird ebenfalls vorteilhaft als Kunststoffteil ausgebildet. Der Umfang dieses Kunststoffrades ist vorteilhaft rinnenförmig ausgenommen. Der Radius der rinnenförmigen Ausnehmung entspricht dem Radius des elastisch-flexiblem Zuggliedes, so dass sich diese in die rinnenförmige Ausnehmung einlegen kann. Als elastisch-flexibles Zugglied wird beispielsweise eine Schraubenfeder, ein Gummiseil o.dgl. eingesetzt.These guide channels are provided with guide inserts in which Tension member guides are provided, the hollow cylindrical inserts and the elastic-flexible tension member with play include. These inserts are beneficial as plastic inserts trained, which ensure smooth running. In the area the end of the guide arms is the drive member via a pulley guided, the smooth-elastic tension member smoothly and deflected quietly. A snagging of the elastic-flexible Tension member is thereby prevented. This pulley is also advantageously designed as a plastic part. The scope This plastic wheel is advantageous gutter-shaped except.

Am Rahmen ist in einer Weiterbildung zumindest einseitig am Rahmen ein Getriebeglied, vorteilhaft werden beidseits des Rahmens je ein Getriebeglied zwischen Antrieb und Wickelwelle vorgesehen. Mit diesem Getriebeglied sind Antrieb und Wickelwelle entkoppelt, so dass unterschiedliche Durchmesserveränderungen beim Auf- bzw. Abwickeln von Antriebsglied und Beschattungsbehang ausgeglichen werden können. Weiterhin ist es vorteilhaft, wenn jeder der Auslagearme eine zweiten Führungskanal aufweist.In a further development, each of the two guide arms with at least provided a first guide channel, open to Laufnute out is. At the frame is in a development at least one-sided on the frame a gear member, are beneficial on both sides of the frame depending a transmission link between the drive and winding shaft provided. With This transmission element drive and winding shaft are decoupled, so that different diameter changes during winding or unwinding Can be compensated by drive member and shading. Furthermore, it is advantageous if each of the delivery arms has a second Has guide channel.

Behang in eine im Querriegel vorgesehenen Nute im wesentlichen voll eintaucht. Alternativ ist die Umlenkrolle für die Schraubenfeder an dem Querriegel des Rahmens so angeordnet, dass der Endstab bei ausgefahrenem Rollladenpanzer oder Rollobehang in eine im Querriegel vorgesehene Nut im wesentlichen voll eintaucht. Es versteht sich von selbst, dass beide Maßnahmen vorgesehen werden können; hierbei kommt es nicht darauf an, dass jede der Maßnahmen ein volles Eintauchen der Endleiste in die Nut bewirkt, sondern dass durch deren Zusammenwirken ein volles Eintauchen zustande kommt.To achieve a complete closing of the Rollobehanges is the elastic-flexible tension member on the armor or behangsseitigen Edge of the end bar so struck that the end bar at extended tank or curtain in one provided in the cross bar Nute immersed substantially fully. Alternatively, the pulley for the coil spring on the crossbar of the frame so arranged that the end bar with extended roller shutter or Rollobehang in a provided in the crossbar groove substantially fully immersed. It goes without saying that both Measures can be provided; this does not matter at that each of the measures a full dipping of the end bar in the groove causes, but that by their interaction a full Immersion comes about.
