Abstract

The roller shutter has a laminated curtain or armoured portion, wound on and off an overhead shaft. The latter is slid by a mechanism along the arm of a support bracket, dependent on the thickness of the coil on it. A first drive wheel (4), driven by the shaft (3), drives a final one (7) if desired by a transmission mechanism (5,6). A fixed slide surface extends along the arm, and a rotary component, driven by the final wheel, travels along it as the shaft turns in the unwinding direction towards the side, from which the door unwinds. The component has a fixed pin towards the wall, engaging in the working position a clamp open to one side.

Description

Die Erfindung betrifft ein Rolltor, insbesondere mit in der Dicke mehrschichtig aufgebautem Behang, mit einer Wickelwelle zum Auf- und Abwickeln des Behanges oder Rolltorpanzers, an der eine Vorrichtung angreift, die die Wickelwelle längs eines Tragarms einer Tragkonsole in Abhängigkeit von der Wickeldicke verschiebt, mit einem von der Wickelwelle angetriebenen ersten Getrieberad, mit einem - gegebenenfalls über einem Getriebezug - getrieblich damit verbundenes letztes Getrieberad und mit einem sich in Richtung des Tragarms erstreckenden, bezüglich der Wandkonsole in der Betriebslage ortsfest angeordneten Translationsteil, längs welchem sich ein von dem letzten Getrieberad angetriebenes Rotationsteil mit geringer werdender Wickeldicke in Richtung auf die Ablaufseite des Wickels bewegt,The invention relates to a roller shutter, in particular with a multi-layered curtain, with a winding shaft for winding and unwinding the curtain or roller shutter curtain, on which a device engages that moves the winding shaft along a support arm of a support bracket depending on the winding thickness a first gearwheel driven by the winding shaft, with a last gearwheel - possibly connected via a gear train - and with a translation part which extends in the direction of the support arm and is fixedly arranged with respect to the wall bracket in the operating position, along which a gearwheel driven by the last gearwheel Rotating part with decreasing winding thickness is moved towards the outlet side of the winding,

Es ist bekannt - DE-U-8708710 -, die an etwa horizontal vom Sturz der zu schließenden Toröffnung abragenden Konsolenschienen abgestützte Wickelwelle mit ihren Lagern entlang dieser Konsolenschienen in Abhängigkeit von dem Durchmessers des Wickels zu verschieben, wodurch man eine gute Einleitung des vom Wickel ablaufenden Behanges in die Torblattführungen seitlich der zu schließenden Toröffnung erreicht. Dieses Vorgehen ist insbesondere bei solchen Behängen erforderlich, die im geöffneten Zustand des Tores verhältnismäßig große Wickel bilden, also - einmal vergleichbare Toröffnungshöhen vorausgesetzt - entsprechend dick ausgebildet sind. Die Steuerung der beiden Bewegungen des Auf- bzw. Abrollens des Behanges einerseits und diejenige der Verschiebelage der Wickelwelle von dem Sturz der zu schließenden Toröffnung, von diesem weg bzw. auf diesen zu sind entsprechend synchronisiert. Ein besonders bevorzugtes Ausführungsbeispiel für eine solche Vorrichtung zum Verschieben der Achse der Wickelwelle eines Rolltores wird in folgenden noch vorgestellt. Solche Vorrichtungen unterliegen allerdings einer gewissen Gefahr für den Fall, daß im Steuergetriebe dieser Vorrichtung ein Defekt - beispielsweise durch ein gebrochenes Zahnrad - auftritt, der die Synchronisation zwischen der Aufrollbewegung des Torblattes und der Verschiebung der Wickelwelle fort von dem Sturz unterbricht. Bei Blockierung der Verschiebebewegung der Welle und gleichzeitig weiterer Aufwickelbewegung des Behanges wird mit wachsendem Wickeldurchmesser eine Klemmung zwischen Wickelwelle und Sturz durch den wachsenden Wickel erfolgen, wodurch der Betrieb des Tores gewaltsam gestört wird und die Gefahr besteht, daß der Behang durch Angriff an dem Sturz im Auflaufbereich des Wickels reißt, so daß der in die Toröffnung hineinragende abgerissene Abschnitt abstürzt. Hierauf wird ebenfalls nachstehend noch näher eingegangen.It is known - DE-U-8708710 - to shift the winding shaft, which is supported on the rail rails projecting approximately horizontally from the lintel of the door opening to be closed, with its bearings along these rail rails depending on the diameter of the winding, thereby providing a good introduction to the winding Blinds in the door leaf guides reached to the side of the door opening to be closed. This procedure is particularly necessary in the case of curtains which form relatively large coils when the door is open, that is to say - provided that the gate opening heights are comparable - are made correspondingly thick. The control of the two movements of the curtain rolling up and down on the one hand and that of the displacement position of the winding shaft from the fall of the door opening to be closed, away from it or towards it are correspondingly synchronized. A particularly preferred exemplary embodiment of such a device for displacing the axis of the winding shaft of a roller shutter is presented in the following. However, such devices are subject to a certain risk in the event that a defect occurs in the control gear of this device, for example due to a broken gear, which interrupts the synchronization between the rolling movement of the door leaf and the displacement of the winding shaft away from the fall. If the shifting movement of the shaft is blocked and, at the same time, further winding movement of the curtain occurs with increasing winding diameter, the winding shaft and lintel become jammed due to the growing winding, whereby the operation of the door is violently disturbed and there is a risk that the curtain will be attacked by the lintel Run-up area of the wrap tears, so that the protruding into the gate opening torn section crashes. This will also be discussed in more detail below.

Um einer solchen Gefahr vorzubeugen ist erfindungsgemäß vorgesehen, daß die Vorrichtung mit einer wandseitigen Halterung aus einem an dem Translationsteil gehaltenen Bauteil mit klammerartiger Öffnung und einem ortsfest gehaltenen Stift versehen ist, der bei in ihre Arbeitslage eingeführte Vorrichtung in die einseitig offene klammerartige Öffnung eingreift.In order to prevent such a danger, the invention provides that the device is provided with a wall-side holder consisting of a component held on the translation part with a clamp-like opening and a stationary pin which engages in the clamp-like opening which is open on one side when the device is inserted into its working position.

Die in Fig. 1 insgesamt mit 5 bezeichnete Vorrichtung ist an der Seite der insgesamt mit 6 bezeichneten Wickelwelle angeordnet, die einen Hohlzylinder 7 aufweist, in den nach innen versetzt eine kreisförmige Seitenronde mittels einer Schweißnaht 9 eingeschweißt ist, welche Öffnungen 10 aufweist.1, which is denoted overall by 5 in FIG. 1, is arranged on the side of the winding shaft denoted overall by 6, which has a hollow cylinder 7, into which a circular side round plate is welded inward by means of a weld seam 9, which has openings 10.

Die Vorrichtung 5 weist ferner sich in Richtung der Achse 11 der Wickelwelle 6 erstreckende Bolzen 12 auf, die in die Öffnungen 10 der Seitenronde 8 mit ihrem freien Ende eingreifen. Das andere Ende der Bolzen 12 ist in einem insgesamt mit 13 bezeichneten Tellerrad festgelegt. Nachdem die Vorrichtung 5 bezüglich der (nicht gezeigten) Wandkonsole fest angeordnet ist, wird bei Drehung der Wickelwelle 6 das Tellerrad über die Öffnungen 10 und die Bolzen 12 angetrieben und dreht sich mit der gleichen Drehzahl wie die Wickelwelle.The device 5 also has bolts 12 which extend in the direction of the axis 11 of the winding shaft 6 and which engage in the openings 10 of the side disc 8 with their free end. The other end of the bolt 12 is fixed in a ring gear designated overall by 13. After the device 5 is fixedly arranged with respect to the wall bracket (not shown), when the winding shaft 6 rotates, the ring gear is driven via the openings 10 and the bolts 12 and rotates at the same speed as the winding shaft.

Das Tellerrad 13 kämmt mit einem Kegelrad 14, welches bezüglich der Vorrichtung 5 fest und senkrecht zu der Achse 11 der Wickelwelle 6 als erstes Glied in einem Getriebezug angeordnet ist.The ring gear 13 meshes with a bevel gear 14, which is arranged as a first link in a gear train with respect to the device 5 and perpendicular to the axis 11 of the winding shaft 6.

Parallel zu dem ersten Zahnrad 15 ist ein mit diesem kämmendes zweites Zahnrad 16 als weiteres Glied des Getriebezuges vorgesehen, zu dem koaxial ein drittes Zahnrad 17 größeren Durchmessers und größerer Zähnezahl als letztes Getrieberad angeordnet. Die beiden Zahnräder 16, 17 können einstückig ausgebildet sein.Parallel to the first gear 15, a second gear 16 meshing with it is provided as a further link of the gear train, to which a third is coaxial Gear 17 of larger diameter and larger number of teeth arranged as the last gear. The two gears 16, 17 can be formed in one piece.

Die dritten Zahnräder 17 kämmen jeweils mit vierten Zahnrädern 18, welche ein Rotationsteil bilden, die eine Hülse 19 mit einem Innengewinde aufweisen, wobei dritte und vierte Zahnräder 17 bzw. 18 gleich sind.The third gears 17 each mesh with fourth gears 18, which form a rotary part, which have a sleeve 19 with an internal thread, third and fourth gears 17 and 18 being the same.

Als Translationsteil ist eine Gewindestange 20 vorgesehen, welche in das Innengewinde des vierten Zahnrades 18 bzw. dessen Hülse 19 eingreift. In Fig. 2 ist die obere Hälfte bezüglich der Achse des Kegelrades 14 mit Bezugszeichen versehen. Bezüglich einer senkrecht zur Zeichenebene durch diese Achse verlaufenden Symmetrieebene ist aber die Vorrichtung spiegelsymmetrisch, so daß klar ist, daß bei Drehung des Kegelrades 14 aufgrund der Drehung der Wickelwelle 6 die Zahnräder des Getriebezuges (15 bis 17) das Rotationsteil 18 und sich dieses gegen das ortsfeste Translationsteil 20 bewegt, was bedeutet, daß beim Abrollen der Wickelwelle die Gewindestange 20 in die Vorrichtung 5 eingefahren wird in dazu vorgesehene Bohrungen 21.A threaded rod 20 is provided as a translation part, which engages in the internal thread of the fourth gear 18 or its sleeve 19. In Fig. 2, the upper half is provided with reference numerals with respect to the axis of the bevel gear 14. With respect to a plane of symmetry running perpendicular to the plane of the drawing through this axis, however, the device is mirror-symmetrical, so that it is clear that when the bevel gear 14 rotates due to the rotation of the winding shaft 6, the gears of the gear train (15 to 17) the rotating part 18 and this against the Fixed translation part 20 moves, which means that when the winding shaft is unrolled, the threaded rod 20 is inserted into the device 5 into bores 21 provided for this purpose.

Ferner ist ersichtlich, daß die Vorrichtung 5 berüglich einer Ebene 22 zweigeteilt so ausgebildet ist, daß die Achse 11 der Wickelwelle 6 aufgenommen werden kann.Furthermore, it can be seen that the device 5 is designed in two parts with respect to a plane 22 so that the axis 11 of the winding shaft 6 can be accommodated.

Beide Gewindestangen 20 sind ferner mittels einer Quertraverse 24 starr miteinander verbunden. In deren Mitte ist eine insgesamt mit 25 bezeichnete Haltevorrichtung angebracht, mittels der die Vorrichtung beispielsweise an der Wand gehäusefest angebracht werden kann.Both threaded rods 20 are also rigidly connected to one another by means of a crossbar 24. In the middle there is a holding device, generally designated 25, by means of which the device can be attached, for example, to the wall in a housing-fixed manner.

Die der Seitenronde 8 zugewandte Seite der Vorrichtung 5 ist ferner mit einer kreisringförmigen Blechscheibe 26 versehen, die in eine umfangsseitig verlaufende Nut 27 an dem Tellerrad 13 eingreift und dieses somit in stetigem kämmenden Eingriff mit dem Kegelrad 14 hält.The side of the device facing the side round 8 5 is also provided with an annular sheet metal disk 26, which engages in a circumferential groove 27 on the ring gear 13 and thus keeps this in constant meshing engagement with the bevel gear 14.

Die Figuren 1 und 2 und die vorstehende, zugehörige Beschreibung geben den Stand der Technik nach der eingangs genannten DE-U-8708710 wieder. Nachfolgend wird anhand der Figuren 3 und 4 die erfindungsgemäße Weiterbildung geschildert:Figures 1 and 2 and the above, associated description represent the prior art according to the aforementioned DE-U-8708710. The further development according to the invention is described below with reference to FIGS. 3 and 4:

Wenn im Rahmen der vorgeschilderten Vorrichtung 5, die eine zwangsgeführte Anrollkonsole darstellt, ein Fehler, beispielsweise durch Brechen eines der Zahnräder, eintritt, stellt sich eine Selbsthemmung ein, was zur Folge hat, daß die Welle 11 für das Aufwickeln des Behanges in einer starren Entfernung vom Sturz verbleibt. Beim Aufrollen des Behanges wird dann der Abstand zur Wand bzw. zum Sturz irgendwann zu klein, so daß durch das Aufwickeln des Behanges - das gilt ganz allgemein für einen Rolltorpanzer - Kräfte entstehen, die eine Komponente auf die Welle 11 in Richtung weg von dem Wandsturz aufweisen. Für diesen Fall soll sich die Vorrichtung 5 aus ihrer ortsfesten wandseitigen Halterung 28 derart lösen, daß die Welle 11 für den Behang frei auf der Konsole gleiten kann. Zu diesem Zwecke ist ein ortsfest gehaltener Stift 30 vorgesehen, der bei in seiner Arbeitslage eingeführter Vorrichtung 5 in einer einseitig offene Klammerung eingreift. Die Klammerung ist derart ausgebildet, daß beim Entlangschieben der Vorrichtung 5 in Richtung auf die Wand bzw. den Sturz eine klammerartige Öffnung 31 sich bei Angriff an dem Stift 30 weitet und dieser in die klammerartig umfaßte Öffnung 31 gerät. Diese Öffnung 31 wird zum Teil von dem Bauteil 29, beispielsweise Druckgußteil, gebildet, an dem auch die Spindeln 20 der Vorrichtung 5 gehalten sind, und zwar derart, daß eine zur Wand hin geöffnete Ausbuchtung 32 entsteht, in die der ortsfeste Stift 30 letztlich gelangt. Ein Teil dieser Öffnung 31 wird im Mittelbereich von einer Nase 33 übergriffen, die zu einem Kunststoff-Klammerteil 34 gehört, das im Bauteil 29 - Druckgußteil - um einen Sollbruch-Stift 35 schwenkbar gelagert ist. Die Nase 33 erstreckt sich in Zugrichtung einer Öse 36 dieses Klammerteils 34, und das als zweiarmiger Hebel ausgebildete Klammerteil 34 weist jenseits des Sollbruch-Stiftes 35 einen federartigen Bügel 37 auf, der an dem Zinkguß- oder Spritzgußteil abgestützt ist, wie dies die Zeichnung zeigt. Dieser Federbügel 35 ist blattfederartig ausgebildet.If, within the framework of the above-described device 5, which is a positively guided rolling console, a fault occurs, for example due to the breakage of one of the gear wheels, self-locking occurs, which has the consequence that the shaft 11 for winding the curtain at a rigid distance remains from the fall. When the curtain is rolled up, the distance to the wall or to the lintel becomes too small at some point, so that when the curtain is rolled up - this applies in general to a roller shutter curtain - forces are generated which cause a component on the shaft 11 in the direction away from the lintel exhibit. In this case, the device 5 is to be released from its fixed wall-side holder 28 in such a way that the shaft 11 can slide freely on the bracket for the curtain. For this purpose, a stationary pin 30 is provided which engages in a bracket open on one side when the device 5 is inserted in its working position. The brackets are designed in such a way that when the device 5 is pushed along in the direction of the wall or the lintel, a bracket-like opening 31 widens when it engages with the pin 30 and the latter comes into the bracket-like opening 31. This opening 31 is formed in part by the component 29, for example a die-cast part, on which the spindles 20 of the device 5 are also held, in such a way that a bulge 32 opens toward the wall, into which the stationary pin 30 ultimately arrives . A part of this opening 31 is overlapped in the central region by a lug 33, which belongs to a plastic clip part 34, which is pivotally mounted in the component 29 - die-cast part - about a predetermined breaking pin 35. The nose 33 extends in the pulling direction of an eyelet 36 of this clamp part 34, and the clamp part 34 designed as a two-armed lever has, beyond the predetermined breaking pin 35, a spring-like bracket 37 which is supported on the zinc casting or injection molding part, as is the case with Drawing shows. This spring clip 35 is designed like a leaf spring.

Durch diese Konstruktion ist es möglich, die Wickelwelle 6 mit der Vorrichtung 5 in die Verarkerung mit dem ortsfesten Stift 30 nach Art eines Schnappverschlusses zu überführen. Will man - aus welchem Grunde auch immer - diese Verbindung zur Wand hin lösen, dann zieht man an der Öse 36, so daß unter Verformung des blattfederförmigen Teils 37 und Drehung um den Sollbruch-Stift 35 die Nase 33 den ortsfesten Stift 30 freigibt. Das ist beispielsweise für Wartungszwecke und dergleichen zweckdienlich.With this construction, it is possible to convert the winding shaft 6 with the device 5 into the marking with the stationary pin 30 in the manner of a snap lock. If you want - for whatever reason - to loosen this connection to the wall, then pull on the eyelet 36, so that the nose 33 releases the stationary pin 30 while deforming the leaf-spring-shaped part 37 and rotating around the predetermined breaking pin 35. This is useful, for example, for maintenance purposes and the like.

Der Sollbruch-Stift 35 hat die Aufgabe, bei einem Versagen der Vorrichtung 5 das Kunststoffteil 34 und damit die Klammer aus seiner Verbindung mit dem Spritzgußteil zu lösen, so daß die Vorrichtung entlang der Konsole frei gleiten kann und dadurch das Torblatt nicht beschädigt wird, sondern im Zweifelsfalle auch weiter betrieben werden kann.The predetermined breaking pin 35 has the task, in the event of a failure of the device 5, to release the plastic part 34 and thus the clamp from its connection with the injection molded part, so that the device can slide freely along the console and thereby not damage the door leaf but in case of doubt it can continue to be operated.
