Description

Die Erfindung betrifft eine Falttür oder Faltwand aus plattenförmigen Türflügeln, die entlang benachbarter Vertikalkanten gelenkig zu Flügelpaaren verbunden sind, welche entlang Vertikalkanten aneinander oder an vertikalen Tragleisten angelenkt sind, mit Tragorganen zwiden Flügelpaaren und an den Enden der Falttür, die in mindestens eine obere Führungsschiene eingreifen und horizontal in der Schließebene verschiebbar sind, wobei sich die Flügelpaare beim Öffnen aus der Schließebene im wesentlichen quer zur Schließebene nach außen auffalten und in geschlossenem Zustand durch mindestens ein von einer Spannfeder beaufschlagtes, an beiden Enden der Falttür befestigtes, horizontal geführtes Zugseil unter Spannung plan in der Schließebene gehalten wird, und mit Führungselementen zum Führen des Zugseils.The invention relates to a folding door or folding wall made of plate-shaped door leaves which are articulated along adjacent vertical edges to form pairs of wings which are hinged to one another or to vertical support strips along vertical edges, with support members between two pairs of wings and at the ends of the folding door which engage in at least one upper guide rail and are horizontally displaceable in the closing plane, the pairs of wings unfolding when opening from the closing plane substantially transversely to the closing plane and in the closed state by at least one horizontally guided traction cable acted upon by a tension spring and fastened to both ends of the folding door under tension is held in the closing plane, and with guide elements for guiding the pull rope.

Eine derartige Falttür oder Faltwand ist aus der US-A-2151 033 bekannt, bei welcher das Zugseil über oder unter der Tür oder Wand geführt ist. Um die quer zur Schließebene gerichteten Schließkräfte zu erzeugen, welche benötigt werden, um die Falttür oder -wand in geschlossenem Zustand plan zu ziehen, nähert sich das Zugseil im Bereich der vertikalen Gelenke jeweils den vom Vertikalgelenk beabstandeten Vertikalkanten an und besitzt daher auch in planem Zustand der Falttür einen zickzackförmigen Verlauf. Aufgrund der relativ geringen Stärke der Türflügel ist jedoch der wechselnde Versatz des Zugseils im Bereich der Vertikalgelenke relativ gering, wodurch die beim Schließen vom Zugseil erzeugten Querkräfte relativ gering bleiben. Die plane Ausrichtung der Türflügel in der Schließebene ist dadurch nicht ausreichend sicher gewährleistet.Such a folding door or folding wall is known from US-A-2151 033, in which the pull cable is guided above or below the door or wall. In order to generate the closing forces directed transversely to the closing plane, which are required to pull the folding door or wall flat in the closed state, the pull cable in the area of the vertical joints approaches the vertical edges spaced from the vertical joint and therefore also has a flat state the folding door has a zigzag shape. Due to the relatively small thickness of the door leaf, however, the changing offset of the pull cable in the area of the vertical joints is relatively small, as a result of which the transverse forces generated by the pull cable when closing are relatively low. The level alignment of the door leaves in the closing plane is therefore not ensured with sufficient certainty.

Aufgabe der Erfindung ist es demgegenüber, die Falttür oder Faltwand der eingangs genannten Art derart weiterzubilden, daß auch bei relativ geringen, in der Schließebene wirkenden Schließkräften alle Flügelpaare stets zuverlässig plan in die Schließebene bringbar sind.In contrast, the object of the invention is to further develop the folding door or folding wall of the type mentioned at the outset in such a way that even with relatively low closing forces acting in the closing plane, all the pairs of wings can always be reliably brought flat into the closing plane.

Diese Aufgabe wird bei der Falttür oder Faltwand der eingangs genannten Art erfindungsgemäß dadurch gelöst, daß das Zugseil in den Führungselementen gegen die innere Oberfläche der Falttür oder Faltwand nach innen ausladend geführt ist und im Bereich der Tragorgane einen relativ großen Abstand, zwischen den Tragorganen einen relativ kleinen Abstand von der Falttür einnimmt.This object is achieved according to the invention in the folding door or folding wall of the type mentioned at the outset in that the pulling rope in the guide elements is guided inwardly projecting against the inner surface of the folding door or folding wall and in the area of the supporting members a relatively large distance, between the supporting members a relative takes a small distance from the folding door.

Die Vorteile der Erfindung liegen insbesondere darin, daß das Zugseil im vorgegebenen Abstand von der inneren Oberfläche der Falttür oder Faltwand geführt wird, so daß der Abstand des Zugseils von der Oberfläche der Tür oder Wand im Bereich der Tragorgane und im Bereich der Vertikalgelenke frei so gewählt werden kann, daß beim Schließen der Tür oder Wand eine ausreichend große Querkraft an den Flügeln angreift und diese plan zieht.The advantages of the invention are in particular that the pull cable is guided at a predetermined distance from the inner surface of the folding door or folding wall, so that the distance of the pull cable from the surface of the door or wall in the area of the support members and in the area of the vertical joints is freely chosen can be that when closing the door or wall a sufficiently large lateral force acts on the wings and pulls them flat.

Die Erfindung eignet sich insbesondere bei einschaligen Falttüren, bei denen aufgrund ihres speziellen Anwendungsbereichs lediglich eine äußere Oberfläche sichtbar ist während die innere Oberfläche z. B. dem Innenraum eines Schrankes oder dergleichen zugewandt ist und vom Benutzer nicht gesehen wird.The invention is particularly suitable for single-leaf folding doors, in which only an outer surface is visible due to their special area of application, while the inner surface z. B. facing the interior of a cabinet or the like and is not seen by the user.

Die Fig. 1 zeigt eine Seitenansicht der erfindungsgemäßen Falttür oder Faltwand. Mehrere plattenförmige Elemente oder Flügel 2 sind entlang ihren Vertikalkanten 3 abwechselnd entweder aneinander oder an vertikalen Tragleisten 4 angelenkt. Jeweils zwei Türflügel 2 sind mit ihrer innenliegenden Vertikalkante 3 aneinander angelenkt (Vertikalgelenk 3a) und bilden ein Flügelpaar 1a ; die außenliegende Vertikalkante 3 ist an einer Tragleiste 6, 8 angelenkt (Vertikalgelenk 3b). Die vertikalen Tragleisten 4 sind an ihrem oberen Ende mit Tragorganen 5, z. B. schwenkbar gelagerten Laufrollenpaaren, versehen und längs einer oberen Führungsschiene 1 horizontal verschiebbar. Die Türflügel 2 liegen in geschlossenem Zustand der Falttür in einer Ebene, der sogenannten Schließebene, die durch die Tragleisten 4, 6, 8 verläuft. Eine außenliegende Tragleiste 6 ist fest mit einem Wandansatz 26 od. dgl. verbindbar, die andere außenliegende Tragleiste 8 stellt das freie Schließende der Falttür dar. Die plattenförmigen Flügel 2 sind alle derart an ihren Vertikalkanten aneinander angelenkt, daß beim Öffnen der Falttür die miteinander verbundenen Vertikalkanten alle in derselben Richtung senkrecht zur Schließebene nach außen ausgestellt werden.1 shows a side view of the folding door or folding wall according to the invention. Several plate-shaped elements or wings 2 are alternately articulated along their vertical edges 3 either to one another or to vertical support strips 4. In each case two door leaves 2 are hinged to one another with their internal vertical edge 3 (vertical joint 3a) and form a pair of leaves 1a; the outer vertical edge 3 is articulated on a support bar 6, 8 (vertical joint 3b). The vertical support strips 4 are at their upper end with support members 5, z. B. pivotally mounted pairs of rollers, provided and horizontally displaceable along an upper guide rail 1. When the folding door is closed, the door leaves 2 lie in one plane, the so-called closing plane, which runs through the support strips 4, 6, 8. An outer support bar 6 is firmly connected to a wall extension 26 or the like. The other outer support bar 8 represents the free closing end of the folding door. The plate-shaped wings 2 are all articulated to one another at their vertical edges such that when the folding door is opened, the interconnected ones Vertical edges are all exposed to the outside in the same direction perpendicular to the locking plane.

Wie in Fig. 1 und insbesondere in Fig. 2 dargestellt ist, ist einen vorgegebenen Abstand unterhalb der Oberkante der Falttür ein Zugseil 22 horizontal über die ganze Breite der Falttür angeordnet. Das Zugseil 22 enthält eine Spannfeder 24 und ist an den außenliegenden Tragleisten 6, 8 an Befestigungselementen 16 einen vorgegebenen Abstand von der Schließebene beabstandet befestigt. Das Zugseil 22 ist ferner an den inneren Tragleisten 4, die zwischen zwei plattenförmigen Flügeln 2 angeordnet sind, einen vorgegebenen Abstand von der Schließebene in Führungselementen oder Seilführungen 18 geführt, die z. B. an den Tragleisten 4 befestig sind. Weiterhin ist das Zugseil 22 an Führungselementen 20 geführt, die etwa in der Nähe der aneinander an gelenkten mittleren Vertikalkanten 3 der Flügelpaare 1a an den Flügeln 2 sitzen.As shown in FIG. 1 and in particular in FIG. 2, a pull cable 22 is arranged horizontally over the entire width of the folding door a predetermined distance below the upper edge of the folding door. The pull rope 22 contains a tension spring 24 and is fastened to the outer support strips 6, 8 on fastening elements 16 at a predetermined distance from the closing plane. The pull rope 22 is also on the inner support strips 4, which are arranged between two plate-shaped wings 2, a predetermined distance from the closing plane in guide elements ment or rope guides 18 out z. B. are attached to the support strips 4. Furthermore, the traction cable 22 is guided on guide elements 20, which are seated on the wings 2 approximately in the vicinity of the middle vertical edges 3 of the wing pairs 1a that are hinged to one another.

Die an den Tragleisten 4, 6, 8 angebrachten Befestigungselemente 16 und Seilführungen 18 besitzen alle denselben Abstand von der äußeren Oberfläche 2a der Falttür, um auf die zwischen jeweils zwei Tragleisten 4, 6, 8 vorhandenen Flügel 2 eine gleichgroße Kraft auszuüben. Durch die Seilführungen 20 wird das Zugseil 22 relativ eng an die plattenförmigen Flügel 2 herangeführt. Der Abstand des Zugseils 22 von den Flügeln 2 ist im Bereich der Seilführungen 20 am kleinsten und nimmt in Richtung auf die Tragleisten 4 bzw. 6, 8 stetig zu. Das Zugseil 22 ist an der inneren Oberfläche 2b der Falttür oder Faltwand angebracht.The fastening elements 16 and cable guides 18 attached to the support strips 4, 6, 8 are all at the same distance from the outer surface 2a of the folding door in order to exert an equally large force on the wings 2 present between two support strips 4, 6, 8. Due to the cable guides 20, the pull cable 22 is brought relatively closely to the plate-shaped wings 2. The distance of the pull cable 22 from the wings 2 is the smallest in the area of the cable guides 20 and increases steadily in the direction of the support strips 4 and 6, 8, respectively. The pull rope 22 is attached to the inner surface 2b of the folding door or folding wall.

Die Länge des Zugseils 22 ist derart bemessen, daß sich das Zugseil 22 am Ende eines Schließvorgange spannt, wenn die Falttür in die Schließebene gezogen und z. B. mittels eines von einer Klinke 30 betätigbaren Schließelements mit dem freien Ende lösbar festgesetzt wird. Wenn sich das Zugseil durch die Wirkung der Zugfeder 24 spannt, werden auf die einzelnen Türflügel 2 an den Seilführungen 20 Kräfte ausgeübt, die eine Komponente senkrecht zur Oberfläche der Flügel 2 besitzen und die Flügel 2 in die Schließebene ziehen und plan in der Schließebene halten.The length of the pull cable 22 is dimensioned such that the pull cable 22 tensions at the end of a closing operation when the folding door is pulled into the closing plane and z. B. is releasably fixed by means of a locking element actuated by a pawl 30 with the free end. When the pull rope is tensioned by the action of the tension spring 24, 20 forces are exerted on the individual door leaves 2 on the cable guides, which have a component perpendicular to the surface of the leaves 2 and pull the leaves 2 into the closing plane and keep them flat in the closing plane.

Beim Öffnen der Falttür, vergl. Fig. 3, entspannt sich die Spannfeder 24 und Zugseil 22, da die Seilführungen 20 allmählich aufeinander zu bewegt werden, so daß das Zugseil 22 dann eine gewisse Überlänge besitzt und locker in den Seilführen 18, 20 gehalten wird. Das Zugseil und die für das Zugseil angebrachten Befestigungselemente und Seilführungen behindern den Schließ- bzw. Öffnungsvorgang der Falttür nicht.When the folding door is opened, see FIG. 3, the tension spring 24 and tension cable 22 relax, since the cable guides 20 are gradually moved towards one another, so that the pull cable 22 then has a certain excess length and is held loosely in the cable guides 18, 20 . The pull rope and the fastening elements and rope guides attached to the pull rope do not hinder the closing or opening process of the folding door.

Fig. 4 zeigt einen der Fig. 2 entsprechenden Querschnitt durch eine weitere Ausführungsform der Erfindung. Jeweils zwei Türflügel 2 sind entlang benachbarten Vertikalkanten 3 zu Flügelpaaren gelenkig miteinander verbunden. Die freien Vertikalkanten der Flügelpaare 1a sind aneinander angelenkt und bilden vertikale Gelenke 3a zwischen benachbarten Flügelpaaren 1a. Über den Gelenken 3a zwischen den benachbarten Flügelpaaren 1a sind Tragorgane 5, z. B. Laufrollen, an der Falttür oder Faltwand befestigt. Die Vertikalgelenke 3b jeweils zwischen den Türflügeln eines Flügelpaars 1a liegen auf der inneren Oberfläche 2b der Falttür, welche z. B. den Innenraum eines Schrankes oder einer Mauernische zugeordnet ist. Die Vertikalgelenke 3a zwischen benachbarten Flügelpaaren 1a liegen auf der äußeren Oberfläche 2a der Falttür. Während zwischen den Flügelpaaren 1a der Tür gemäß den Fig. 1 bis 3 vertikale Tragleisten eingesetzt sind, sind benachbarte Flügelpaare 1a in Fig. 4 unmittelbar aneinander angelenkt, und die Tragorgane 5 sitzen über diesen Verbindungsstellen an einer geeigneten Konstruktion (nicht dargestellt).FIG. 4 shows a cross section corresponding to FIG. 2 through a further embodiment of the invention. In each case two door leaves 2 are articulated to one another along adjacent vertical edges 3 to form wing pairs. The free vertical edges of the wing pairs 1a are articulated to one another and form vertical joints 3a between adjacent wing pairs 1a. Over the joints 3a between the adjacent pairs of wings 1a support members 5, z. B. castors, attached to the folding door or folding wall. The vertical joints 3b each between the door wings of a pair of wings 1a lie on the inner surface 2b of the folding door, which z. B. is assigned to the interior of a cabinet or a wall recess. The vertical joints 3a between adjacent wing pairs 1a lie on the outer surface 2a of the folding door. While vertical support strips are inserted between the wing pairs 1a of the door according to FIGS. 1 to 3, adjacent wing pairs 1a in FIG. 4 are articulated directly to one another, and the support members 5 sit over these connection points on a suitable construction (not shown).

Auf der inneren Oberfläche 2b der Falttür ist in vorgegebenem Abstand unterhalb der Oberkante ein Zugseil 22 horizontal zwischen den Enden der Falttür angeordnet. Das Zugseil 22 enthält eine Spannfeder 24 (nicht dargestellt) und wird beim Schließen der Falttür gespannt.
