Description

Die Erfindung betrifft eine Hochschiebesicherung für Rolladen und Rolltore mit einem auf einer Welle aufwickelbaren, aus gelenkig miteinander verbundenen Rolladenlamellen bestehenden Rolladenpanzer, wobei eine mehrgliedrige Aufhängung für den Rolladenpanzer an der Welle aus gelenkig miteinander verbundenen Elementen vorgesehen ist.The invention relates to a push-up device for roller shutters and roller shutters with a roller shutter curtain which can be wound up on a shaft and consists of roller shutter slats which are connected to one another in an articulated manner, wherein a multi-unit suspension for the roller shutter curtain is provided on the shaft from elements which are connected to one another in an articulated manner.

Die Sicherung von Rolladen und Rolltoren gegen Hochschieben von außen durch Herstellen eines quasi starren Zustandes zwischen den Elementen der Aufhängung des Rolladenpanzers oder zwischen den einzelnen Rolladenlamellen des Rolladenpanzers ist bekannt.Securing roller shutters and roller doors against being pushed up from the outside by producing a quasi-rigid state between the elements of the suspension of the roller shutter curtain or between the individual roller shutter slats of the roller shutter curtain is known.

Die DE-OS 23 03 025 zeigt eine Ausgestaltung zur Herstellung einer formschlüssigen Verklemmung der gelenkig untereinander verbundenen Rolladenlamellen auf, wobei an den Längsseiten der Rolladenlamellen Blockierglieder befestigt sind, die beim Zusammendrücken der Lamellen durch Einschieben einer Lasche in eine U-Förmige Führung sich selbsttätig gegenseitig verriegeln und auch gleichzeitig die Lamellen untereinander in ihrer Dreh- und Längsbewegung blockieren.DE-OS 23 03 025 shows an embodiment for producing a form-fitting jamming of the roller shutter slats which are articulated to one another, blocking members being fastened to the longitudinal sides of the roller shutter slats, which mutually automatically when the slats are pressed together by pushing a tab into a U-shaped guide lock and at the same time block the slats with each other in their rotational and longitudinal movement.

Nachteilig dabei ist, daß die Blockierglieder aufwendig sind und nur an den Enden der Lamellen angebracht werden können, so daß bei größeren Rolladenbreiten keine starre Lamellenwand zu erreichen ist.The disadvantage here is that the blocking members are complex and can only be attached to the ends of the slats, so that no rigid slat wall can be achieved with larger shutter widths.

Bei einer anderen Ausgestaltung sind die Rolladenlamellen besonders ausgebildet, so daß sie im zusammengeschobenen Zustand sich selbst verriegeln und sich gegenseitig nicht mehr verdrehen können. Bei dieser profilabhängigen Lösung des Problems können nur spezielle Rolladenlamellen mit zusätzlichen Anschlägen verwendet werden, wodurch sich die Rolladenfertigung unverhältnismäßig verteuert.In another embodiment, the roller shutter slats are specially designed so that when they are pushed together they lock themselves and can no longer twist each other. With this profile-dependent solution to the problem, only special roller shutter slats with additional stops can be used, which makes roller shutter manufacture disproportionately expensive.

Die DE-OS 24 05 078 geht davon aus, Rolläden aus handelsüblichen Rolladenlamellen durch Anordnen von besonderen Sperrgliedern in die untere Aufnahmenut der Rolladenlamellen gegen Verschieben der Rolladenlamellen gegeneinander und auch gegen Verdrehen oder Verkippen im geschlossenen Zustand zu sichern. Die Sperrglieder sind je nach Rolladenbreite an den Enden der Rolladenlamellen oder in gleichen Abständen über die gesamte Rolladenbreite verteilt angeordnet.DE-OS 24 05 078 is based on securing roller shutters made from commercially available roller shutter slats by arranging special locking elements in the lower receiving groove of the roller shutter slats against displacement of the roller shutter slats against one another and also against twisting or tilting in the closed state. The locking elements are depending on the shutter width arranged at the ends of the roller shutter slats or at equal intervals across the entire roller shutter width.

Nachteilig ist, daß eine Vielzahl derartiger Sperrglieder erforderlich sind, die beim Zusammenschieben der einzelnen Rolladenlamellen zum Rolladenpanzer in entsprechende Ausnehmungen in den Stegen der Lamellen eingesetzt und durch Kleben oder Verstiften fixiert werden müssen.The disadvantage is that a large number of such locking members are required, which have to be inserted into corresponding recesses in the webs of the slats when the individual roller shutter slats are pushed together to form the roller shutter curtain and must be fixed by gluing or pinning.

Nach der DE-OS 41 38 206 erfolgt die Sicherung von Rolladen oder Rolltoren gegen Hochschieben durch eine aus drei verschiedenen Elementen bestehende Aufhängung für den Rolladenpanzer. Die Elemente, die aus zwei aufeinander gedoppelten Blechstreifen bestehen, sind über Gelenkaugen gliederkettenartig untereinander verbunden, und jedes Element weist eine das Gelenk übergreifende, in den Bereich des Nachbarelementes ragende Zunge auf. Im herabgelassenen Zustand des Rolladenpanzers befinden sich die Elemente in Überstrecklage, wobei die Zunge des einen Elementes an dem benachbarten Element anliegt und sich dort abstützt. Dadurch werden die Elemente der Aufhängung in einer nahezu geraden Wirkungslinie gehalten. Die Verriegelungsvorrichtung ist besonders für schwere Rolladen und Rolltore mit einem Getriebemotorantrieb vorgesehen, der die Endstellung in Überstrecklage sicher erreicht. Bei einem Rolladen mit Gurtroller ist ein Anschlageinsteller in Form einer zusätzlichen Feder erforderlich.According to DE-OS 41 38 206, roller shutters or roller doors are secured against being pushed up by a suspension for the roller shutter curtain consisting of three different elements. The elements, which consist of two sheet metal strips which are doubled one on top of the other, are connected to one another in the manner of link chains by means of articulated eyes, and each element has a tongue which overlaps the articulation and projects into the region of the neighboring element. When the roller shutter curtain is lowered, the elements are in the overstretched position, the tongue of one element bearing against the adjacent element and being supported there. This keeps the suspension elements in an almost straight line of action. The locking device is especially designed for heavy roller shutters and roller doors with a geared motor drive, which safely reaches the end position in the extended position. A stop adjuster in the form of an additional spring is required for a roller shutter with a belt roller.

In der DE-OS 41 08 423 wird ein Gelenkstück beschrieben, das zwischen Rolladenpanzer und Welle angeordnet ist, und mit dessen Hilfe eine lagenstabile Sperre der Welle gegen ein Hochschieben des Rolladenpanzers von außen angestrebt wird. Das Gelenkstück besteht aus einem an der Welle befestigten oberen Element, einem mittleren Element, das schwenkbar mit dem oberen Element und einem weiteren unteren Element verbunden ist; an dem unteren Element befindet sich die Aufhängeschiene für die oberste Lamelle des Rolladenpanzers. Aus dem oberen Element springt nach unten eine Nase vor, die einen Anschlag darstellt und die Schwenkbewegung des mittleren Elements gegen das obere Element begrenzt. Bei herabgelassenem Rolladen bilden das obere und mittlere Element infolge der Begrenzung der Schwenkbewegung ein nahezu starres Gebilde. Mit Hilfe einer von Hand einstellbaren Justiervorrichtung am mittleren Element erfolgt ein Ausrichten des unteren Elementes durch Abwärtsschwenken um die mittlere Drehachse. Das Gelenkstück funktioniert dann wie ein etwa auf die Mitte der Welle gerichteter, geradliniger Sperrstab, wobei die Klemmwirkung zwischen den einzelnen Elementen durch die vorspringenden Nasen und die handbetätigte Justiervorrichtung erzielt wird.DE-OS 41 08 423 describes a joint piece which is arranged between the roller shutter curtain and the shaft, and with the aid of which a positionally stable locking of the shaft against pushing up the roller shutter curtain from the outside is sought. The joint piece consists of an upper element fastened to the shaft, a middle element which is pivotably connected to the upper element and a further lower element; On the lower element there is the suspension rail for the top slat of the roller shutter curtain. A nose projects out of the upper element, which represents a stop and limits the pivoting movement of the central element against the upper element. When the roller shutter is lowered, the upper and middle element form an almost rigid structure due to the limitation of the pivoting movement. With the help of a manually adjustable adjustment device on the middle element, the lower element is aligned by swiveling downward about the central axis of rotation. The joint piece then functions like a straight locking rod directed towards the middle of the shaft, the clamping effect between the individual elements being achieved by the projecting lugs and the manually operated adjusting device.

Nach dem DE-GM 92 01 569.7 ist an einem elektrisch betriebenen Rolladen eine dreigliedrige Aufhängung vorgesehen, wobei die Enden der äußeren Glieder formschlüssig in die beiden Enden des mittleren Gliedes eingreifen können und in diese im herabgelassenen Zustand des Rolladenpanzers eingeschoben werden. Dadurch wird eine starre Verbindung des Panzers mit der Welle erzeugt. Der Formschluß wird aufgehoben, wenn die Glieder beim Aufwickeln des Rolladens gegen einen Federdruck auseinandergezogen werden.According to DE-GM 92 01 569.7, a three-part suspension is provided on an electrically operated roller shutter, the ends of the outer links being able to engage in a form-fitting manner in the two ends of the middle link and being inserted into them in the lowered state of the roller shutter curtain. This creates a rigid connection between the tank and the shaft. The positive connection is released if the links are pulled apart against spring pressure when the roller shutter is wound up.

Der Erfindung liegt die Aufgabe zugrunde eine Hochschiebevorrichtung für Rolladen und Rolltore zu entwickeln, die als Aufhängung für den Rolladenpanzer zwischen dem Rolladenpanzer und der Rolladenwelle angeordnet ist und aus mehreren Elementen besteht, wobei beim Hochschieben des Rolladenpanzers die Einzelelemente sich so ausrichten, daß die Aufhängung sich wie ein starrer Stab verhält.The invention has for its object to develop a push-up device for roller shutters and roller doors, which is arranged as a suspension for the roller shutter curtain between the roller shutter curtain and the roller shutter shaft and consists of several elements, the individual elements aligning so that the suspension itself when pushing up the roller shutter curtain behaves like a rigid rod.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß die Elemente der Aufhängung Sperrglieder und ein Kupplungsglied umfassen, daß die Sperrglieder und das Kupplungsglied am oberen Ende eine Nase und die Sperrglieder außerdem am unteren Ende eine Einbuchtung aufweisen, und daß die Nasen des Kupplungsgliedes und der Sperrglieder in die zugeordneten Einbuchtungen der jeweils benachbarten Sperrglieder eingreifen.This object is achieved in that the elements of the suspension comprise locking members and a coupling member, that the locking members and the coupling member have a nose at the upper end and the locking members also have an indentation at the lower end, and that the lugs of the coupling member and the locking members in engage the associated indentations of the adjacent locking members.

Eine vorteilhafte Weiterbildung der Erfindung ist dadurch gekennzeichnet, daß das Kupplungsglied an seiner Oberseite eine Einkerbung aufweist.An advantageous development of the invention is characterized in that the coupling member has a notch on its top.

Die mit der Erfindung erzielten Vorteile bestehen insbesondere darin, daß die Elemente der Hochschiebesicherung einfach gestaltet und daher als Strangpreßprofile kostengünstig herstellbar sind. Die Hochschiebesicherung läßt sich leicht zusammenbauen und problemlos für jeden Rolladen verwenden.The advantages achieved by the invention are, in particular, that the elements of the anti-lift device are simple in design and can therefore be produced inexpensively as extruded profiles. The anti-lift device is easy to assemble and can easily be used for any roller shutter.

Fig. 1 zeigt eine perspektivische Ansicht einer erfindungsgemäßen Hochschiebesicherung, und in Fig. 2 ist eine Seitenansicht des Ausführungsbeispieles aus Fig. 1 dargestellt. Die Hochschiebesicherung besteht aus einer mehrgliedrigen Aufhängung 7 für den Rolladenpanzer 4 an die Rolladenwelle 5. Wie aus Fig. 2 hervorgeht, setzt sich die Aufhängung 7 aus einer Kombination von zwei verschiedenartigen, gelenkig miteinander verbundenen Elementen 1, 6 zusammen: aus vorzugsweise drei Sperrgliedern 1 und einem Kupplungsglied 6, wobei die Anzahl der Sperrglieder 1 sich nach der Größe des Rolladenkastens 17 und dem Ballendurchmesser des aufgewickelten Rolladens richtet.FIG. 1 shows a perspective view of a push-up safety device according to the invention, and FIG. 2 shows a side view of the exemplary embodiment from FIG. 1. The anti-lift device consists of a multi-unit suspension 7 for the roller shutter curtain 4 on the roller shutter shaft 5. As can be seen from FIG. 2, the suspension 7 is composed of a combination of two different types of elements 1, 6 which are connected to one another in an articulated manner: preferably three locking members 1 and a coupling member 6, the number of locking members 1 depending on the size of the roller shutter box 17 and the bale diameter of the wound roller shutter.

Das oberste Sperrglied 1 ist mit Hilfe eines Aufhängebolzens 10 an zwei auf die Welle 5 aufgeschobenen Ringen 8 drehbar befestigt, während die Verbindung zwischen dem untersten Sperrglied 1 und dem Rolladenpanzer 4 das Kupplungsglied 6 herstellt; dabei wird die oberste Lamelle 16 des Rolladenpanzers 4 in bekannter Weise in einen Haken 14 am unteren Ende des Kupplungsgliedes 6 eingehängt.The uppermost locking member 1 is rotatably fastened by means of a suspension bolt 10 to two rings 8 pushed onto the shaft 5, while the connection between the lowest locking member 1 and the roller shutter curtain 4 produces the coupling member 6; the uppermost lamella 16 of the roller shutter curtain 4 is suspended in a known manner in a hook 14 at the lower end of the coupling member 6.

Fig. 3 und Fig. 4 zeigen Einzeldarstellungen eines Kupplungsgliedes 6 und eines Sperrgliedes 1 in Seitenansicht. Beide Glieder 1, 6 sind bogenförmig ausgebildet und als Strangpreßprofile leicht herstellbar. Das obere Ende der Glieder 1, 6 ist als Drehlager 12 ausgebildet dessen äußeres Ende zu einer Nase 3 geformt ist; außerdem weist das Sperrglied am unteren Ende unmittelbar vor der dem Drehlager 12 zugeordneten Drehleiste 13 noch eine Einbuchtung 2 auf (Fig. 4).3 and FIG. 4 show individual representations of a coupling member 6 and a locking member 1 in a side view. Both links 1, 6 are arched and easily manufactured as extruded profiles. The upper end of the links 1, 6 is designed as a pivot bearing 12, the outer end of which is shaped into a nose 3; in addition, the locking member has an indentation 2 at the lower end immediately in front of the rotary bar 13 assigned to the rotary bearing 12 (FIG. 4).

In den Fig. 5a und 5b sind jeweils Ausschnitte aus der Aufhängung 7 schematisch in Seitenansicht dargestellt. Die Ausschnitte zeigen die drehbare Verbindung zwischen zwei Sperrgliedern 1 bei hochgezogenem, auf die Welle 5 aufgewickeltem Rolladen (Fig. 5a) und bei herabgelassenem Rolladen (Fig. 5b). Beim Aufwickeln des Rolladens auf die Welle 5 schmiegen sich die bogenförmigen Glieder 1, 6 der Aufhängung 7 durch entsprechende Drehung der Glieder 1, 6 in den Drehlagern 12 an die Welle 5 an. Aussparung 2 und Nase 3 benachbarter Glieder 1, 6 streben dabei auseinander und bilden eine weite Öffnung 15 (Fig. 5a).5a and 5b, sections of the suspension 7 are each shown schematically in a side view. The cutouts show the rotatable connection between two locking members 1 with the roller shutter pulled up, wound onto the shaft 5 (FIG. 5a) and with the roller shutter lowered (FIG. 5b). When winding the roller shutter on the shaft 5, the arcuate members 1, 6 of the suspension 7 nestle by appropriate Rotation of the links 1, 6 in the pivot bearings 12 on the shaft 5. Recess 2 and nose 3 of adjacent links 1, 6 strive apart and form a wide opening 15 (Fig. 5a).

Im herabgelassenem Zustand, wenn der Rolladenpanzer 4 auf einer glatten Fläche, z. B. der Fensterbank, aufsitzt, greifen die Nasen 3 des Kupplungsgliedes 6 und der Sperrglieder 1 in die zugeordneten Aussparungen 2 der jeweils benachbarten Sperrglieder 1 ein, wie in Fig. 5b an Hand von zwei benachbarten Sperrgliedern 1 dargestellt ist. Beim Versuch des Hochschiebens des Rolladenpanzers 4 arretieren sich die Glieder 1, 6 der Aufhängung 7 gegenseitig, indem die Nasen 3 sich fest in die zugeordneten Aussparungen 2 eindrücken. Die Aufhängung 7 verhält sich dann wie ein starrer Stab, der durch die zum Anheben des Rolladenpanzers 4 von unten angesetzte Kraft um den Aufhängebolzen 10 der Aufhängung 7 gegen die Wand 18 des Rolladenkastens 17 geschwenkt wird und sich an dieser abstützt. Die starre Aufhängung 7 ist zwischen Wand 18 und Rolladenwelle 5 verklemmt. Die Verklemmung wird aufgehoben, wenn durch Drehen der Rolladenwelle 5 die Glieder 1, 6 der Aufhängung 7 sich auseinanderdrehen und dadurch der gegenseitige Eingriff gelöst wird.In the lowered state when the roller shutter 4 on a smooth surface, for. B. the window sill, the lugs 3 of the coupling member 6 and the locking members 1 engage in the associated recesses 2 of the adjacent locking members 1, as shown in Fig. 5b with two adjacent locking members 1. When trying to push up the roller shutter curtain 4, the links 1, 6 of the suspension 7 lock each other by the lugs 3 pressing firmly into the associated recesses 2. The suspension 7 then behaves like a rigid rod which is pivoted by the force applied from below for lifting the roller shutter curtain 4 around the suspension bolt 10 of the suspension 7 against the wall 18 of the roller shutter box 17 and is supported on the latter. The rigid suspension 7 is clamped between the wall 18 and the roller shutter shaft 5. The jamming is released when the members 1, 6 of the suspension 7 rotate apart by rotating the roller shutter shaft 5 and the mutual engagement is thereby released.

In Fig. 6 ist ein Ausführungsbeispiel einer vorteilhaften Weiterbildung der Erfindung in gleicher Darstellung wie in Fig. 2 gezeigt. Bei dieser Ausbildung der Erfindung ist das Kupplungsglied 6 am unteren Ende außen mit einer Einkerbung 9 versehen. Beim unbefugten Anheben des Rolladenpanzers 4 und dem Einschwenken der in einem quasi starren Zustand befindlichen Aufhängung 7 gegen die Wand 18 des Rolladenkastens 17 rastet die Einkerbung 9 des Kupplungsgliedes 6 in einen an der Wand 18 angebrachten Anschlag 11 ein und sperrt den Rolladen gegen ein Hochschieben. Durch diese Ausbildung der Erfindung wird die vertikale Belastung der Rolladenwelle 5, wie sie beim Verklemmen der Aufhängung 7 in der ersten Ausführung der Erfindung auftritt, vermieden.FIG. 6 shows an exemplary embodiment of an advantageous development of the invention in the same representation as in FIG. 2. In this embodiment of the invention, the coupling member 6 is provided on the outside with a notch 9 at the lower end. When unauthorized lifting of the roller shutter armor 4 and the pivoting of the suspension 7, which is in a quasi-rigid state, against the wall 18 of the roller shutter box 17, the notch 9 of the coupling member 6 engages in a stop 11 attached to the wall 18 and blocks the roller shutter from being pushed up. This embodiment of the invention avoids the vertical loading of the roller shutter shaft 5, as occurs when the suspension 7 is jammed in the first embodiment of the invention.
