Abstract

The invention relates to a roller shutter with a large number of laterally guided roller shutter profiles which are articulated on one another. On their rear side, these roller shutter profiles have groove-shaped recesses, in which the teeth of toothed wheels, arranged on a guide tube, engage as drive means. The guide tube is surrounded by a torsion spring which is fastened on the one hand to the central stationary shaft, which passes through the guide tube, and on the other hand to the guide tube itself. The guide tube is furthermore closed on both sides by end caps which support the shaft and are inserted into its opening. The characteristic feature of the invention is seen in that the end caps (5), which are inserted into the opening of the guide tube (3) on the end sides, project out of the opening with part regions (51). From these part regions (51), there project beyond the outer circumference of the guide tube (3) tooth-like projections (511) which are distributed uniformly on the circumference. These projections (511) engage in corresponding receiving grooves (421) which extend over the axial length of the toothed wheels (4) and are arranged on the inner circumference of the central bore (42) of the toothed wheels (4). The end caps (5) are at the same time mounted rotatably movably on the shaft (6). The toothed wheels (4) are detachably connected to one another with the end caps (5) via the guide tube (3), in each case by means of mechanical fastening means (41) which reach through.

Description

Die Erfindung betrifft einen Rolladen mit einer Vielzahl von aneinander angelenkten, seitlich geführten Rolladenprofilen, welche auf ihrer Rückseite nutenförmige Vertiefungen aufweisen, in die Zähne von auf einem Führungsrohr angeordneten Zahnräder als Antriebsmittel eingreifen, wobei das Führungsrohr eine Torsionsfeder umschließt, die einerseits an der zentralen, feststehenden und das Führungsrohr durchsetzenden Achse und andererseits an dem Führungsrohr selbst befestigt ist, und wobei das Führungsrohr beidseitig durch die Achse tragende, in sein Lumen eingesetzte Endkappen verschlossen ist.The invention relates to a roller shutter with a plurality of hinged, laterally guided roller shutter profiles, which have groove-shaped depressions on their back, engage in the teeth of gearwheels arranged on a guide tube as drive means, the guide tube enclosing a torsion spring which, on the one hand, on the central, fixed and passing through the guide tube and on the other hand is fastened to the guide tube itself, and wherein the guide tube is closed on both sides by the axis carrying end caps inserted into its lumen.

In der Französischen Patentanmeldung 2 421 259 ist ein solcher Rolladen beschrieben, der beispielsweise für das Schließen einer Garage oder eines Lastwagenaufbaus verwendet werden kann. Bei dem bekannten Rolladen besteht der Panzer aus einzelnen Panzerelementen, die gelenkig miteinander verbunden sind. Diese Panzerelemente werden von einer horizontalen Antriebswelle bewegt, auf der eine Torsionsfeder gehaltert ist. Antriebswelle und Torsionsfeder sind von einem rohrförmigen Zylinder umgeben, an dessen äußerem Umfang längsverschiebliche Zahnräder angeordnet sind. Diese Zahnräder greifen in die in den einzelnen Panzerelementen gebildeten Aussparungen ein und dienen dabei als Rolladenantrieb beim Aufrollen bzw. Herablassen des Türpanzers.Such a roller shutter is described in French patent application 2 421 259, which can be used, for example, for closing a garage or a truck body. In the known roller shutter, the armor consists of individual armor elements which are connected to one another in an articulated manner. These armor elements are moved by a horizontal drive shaft on which a torsion spring is held. The drive shaft and torsion spring are surrounded by a tubular cylinder, on the outer circumference of which longitudinally displaceable gear wheels are arranged. These gearwheels engage in the recesses formed in the individual armored elements and serve as a roller shutter drive when the door armor is rolled up or lowered.

Der Antrieb des Türpanzers erfolgt durch die Antriebswelle über die Zahnräder, die gleichzeitig die Führung des Türpanzers bei den verschiedenen Abrollbewegungen übernehmen. Die seitliche Führung erfolgt dabei in Führungsschienen, in denen die Endbereiche der einzelnen Panzerelemente während der Bewegungsvorgänge geführt sind.The door armor is driven by the drive shaft via the gears, which at the same time guide the door armor during the various rolling movements. The lateral guidance takes place in guide rails in which the end areas of the individual armored elements are guided during the movement processes.

Die Ablaufbewegung des bekannten Rolladens wird dabei durch die auf der Antriebswelle angeordnete Torsionsfeder unterstützt, die als klassischer Gewichtsausgleich dient.The running movement of the known roller shutter is supported by the torsion spring arranged on the drive shaft, which serves as a classic weight compensation.

Das System ist so eingerichtet, daß bei geschlossenem Türpanzer die Torsionsfeder gespannt ist. Wird der Türpanzer zum Öffnen entriegelt, neigt die Torsionsfeder dazu, sich aus dem Spannungszustand in die Ruhelage auszudehnen und versetzt dabei den rohrförmigen Zylinder mit den Zahnrädern in eine in Öffnungsrichtung wirkende Drehbewegung. Über die Zahnräder und deren Eingriff in die Aussparungen der einzelnen Panzerelemente wird der Türpanzer in die Offenstellung bewegt, wobei die Wirkung der Torsionsfeder bis zur Totalöffnung des Türpanzers durch geringfügiges Nachschieben durch das Bedienungspersonal unterstützt werden kann.The system is set up so that the torsion spring is tensioned when the door armor is closed. If the door armor is unlocked for opening, the torsion spring tends to expand from the tensioned state into the rest position and in doing so sets the tubular cylinder with the gearwheels in a rotational movement acting in the opening direction. The door armor is moved into the open position via the gears and their engagement in the recesses of the individual armor elements, the action of the torsion spring being able to be supported by the operating personnel until the door armor is completely opened by slight pushing.

Der bekannte Rolladen mit seinem Antriebsmechanismus ist zwar einsetzbar, berücksichtigt jedoch nicht in ausreichendem Maße die Tatsache, daß die Torsionsfeder bei zunehmendem Gebrauch mehr und mehr von ihrer ursprünglichen Vorspannung verlieren kann. Dieser aus technischen oder Materialgründen entstehende Spannungsverlust kann bei dem bekannten Rolladenaufbau nur dadurch aufgehoben werden, daß die Systemeinheit Antriebswelle, Torsionsfeder und rohrförmiger Zylinder aus der Lagerung gelöst wird. Der gesamte Aufbau muß dann vom Rolladen abgenommen werden und erst dann kann die Torsionsfeder nach Abnahme der Endkappen von der Antriebswelle neu gespannt werden. Dies ist ein sehr arbeitsintensiver und zeitaufwendiger Vorgang.The known roller shutter with its drive mechanism can be used, but does not take sufficient account of the fact that the torsion spring can lose more and more of its original prestress with increasing use. This loss of tension, which arises for technical or material reasons, can only be eliminated in the known roller shutter structure in that the drive shaft, torsion spring and tubular cylinder system unit are released from the bearing. The entire structure must then be removed from the roller shutter and only then can the torsion spring be re-tensioned after removing the end caps from the drive shaft. This is a very labor intensive and time consuming process.

Hier setzt die Erfindung ein, die es sich zur Aufgabe gestellt hat, den beim Stand der Technik erforderlichen Aufwand zum Spannen der Torsionsfeder zu minimieren und ein Antriebssystem anzugeben, bei dem zum Spannen der Torsionsfeder ein Abbau des Bewegungssystems von den seitlichen Begrenzungswänden des Rolladens nicht mehr erforderlich ist. Erfindungsgemäß wird dazu vorgeschlagen, daß in das Lumen des Führungsrohres endenseitig eingesetzte Endkappen mit Teilbereichen aus dem Lumen herausragen, daß von diesen Teilbereichen am Umfang gleichmäßig verteilte zahnartige Vorsprünge über den äußeren Umfang des Führungsrohres vorstehen, daß diese Vorsprünge in über die Achslänge der Zahnräder verlaufende, korrespondierende, am inneren Umfang der Mittelbohrung der Zahnräder angeordnete Aufnahmenuten eingreifen, daß die Endkappen auf der Achse drehbeweglich gelagert sind, und daß die Zahnräder mit den Endkappen über mechanische Befestigungsmittel jeweils lösbar miteinander verbunden sind.This is where the invention comes in, which has set itself the task of minimizing the effort required in the prior art for tensioning the torsion spring and specifying a drive system in which, for tensioning the torsion spring, the movement system is no longer broken down from the lateral boundary walls of the roller shutter is required. According to the invention it is proposed that end caps with end portions inserted into the lumen of the guide tube protrude from the lumen, that tooth-like projections evenly distributed on the circumference of these partial portions protrude beyond the outer circumference of the guide tube, that these protrusions extend over the axial length of the gear wheels running, corresponding, on the inner circumference of the center bore of the gears receiving grooves engage that the end caps are rotatably mounted on the axis and that the gears are releasably connected to the end caps by mechanical fasteners.

Vorteilhaft ist dabei das eine freie Ende der Torsionsfeder mit dem in das Lumen des Führungsrohres eingesetzten Endkappenstutzen über ein mechanisches Befestigungsmittel lösbar verbunden, während das andere freie Ende der Torsionsfeder an der Achse selbst angelenkt ist. Weiterhin hat es sich als zweckmäßig erwiesen, daß an den aus dem Lumen des Führungsrohres herausragenden Teilbereichen der Endkappen ein sechskantiger Fortsatz für das Angreifen eines Verdrehwerkzeuges angeformt ist. Über diesen sechskantigen Fortsatz ist nach dem Lösen des mechanischen Befestigungsmittels zwischen Zahnrad und Endkappe und nach dem Verschieben des Zahnrades aus der Nutenführung über das Führungsrohr die Endkappe mit dem Führungsrohr zur Spannung der Torsionsfeder verdrehbar.Advantageously, the one free end of the torsion spring is detachably connected to the end cap socket inserted into the lumen of the guide tube by means of a mechanical fastening means, while the other free end of the torsion spring is articulated on the axle itself. Furthermore, it has proven to be expedient for a hexagonal extension for the engagement of a twisting tool to be formed on the portions of the end caps which protrude from the lumen of the guide tube. About this hexagonal extension after loosening the mechanical fastener between the gear and end cap and after moving the gear from the groove guide over the guide tube, the end cap with the guide tube for tensioning the torsion spring.

Der erfindungsgemäße Rolladen ermöglicht das Einregeln der Torsionsspannung ohne großen Montage- bzw. Demontageaufwand. Ein solches Einregeln kann beispielsweise erforderlich werden, wenn eine Ermüdung der Torsionsfeder-Vorspannung durch mehrfachen Gebrauch eingetreten ist oder das Bedienungspersonal eine andere Einstellung der Spannungsverhältnisse der Torsionsfeder wünscht. Es besteht auch die Möglichkeit, den gesamten Rolladensatz ohne Vorspannung der Torsionsfeder an seinem Einsatzort, z.B. als Verschluß einer Möbelöffnung, komplett einzubauen. Die Torsionsfederspannung kann in dem gewünschten Verhältnis dann an Ort und Stelle vor der ersten eigentlichen Benutzungshandlung eingestellt werden, indem das mechanische Befestigungsmittel zwischen Zahnrad und Endkappe gelöst und das Zahnrad aus der Nutenführung über das Führungsrohr verschoben worden ist.The roller shutter according to the invention enables the torsional tension to be adjusted without much assembly or disassembly. Such adjustment may be necessary, for example, if the torsion spring preload has become fatigued as a result of repeated use or if the operating personnel desires a different setting of the tension ratios of the torsion spring. It is also possible to completely install the entire set of roller shutters at their place of use without pretensioning the torsion spring, for example as a closure for a furniture opening. The torsion spring tension can then be adjusted in the desired ratio on the spot before the first actual usage action by loosening the mechanical fastening means between the gear wheel and the end cap and moving the gear wheel out of the groove guide over the guide tube.

Jetzt kann über ein Verdrehwerkzeug der nach außen ragende sechskantige Fortsatz der Endkappe verdreht und damit die Spannung der Torsionsfeder eingestellt werden. Danach wird das auf das Führungsrohr verschobene Zahnrad mit seinen Aufnahmenuten wieder in die zahnartigen Vorsprünge der aus dem Lumen des Führungsrohres herausragenden Teilbereiche der Endkappen eingeschoben und mittels des mechanischen Befestigungsmittels auf der Endkappe festgelegt. Dieses mechanische Befestigungsmittel durchgreift auch den zugeordneten Endbereich des Führungsrohres, so daß im Endzustand das Zahnrad, die Endkappe und das Führungsrohr eine drehbare Einheit bilden.Now the outwardly projecting hexagonal extension of the end cap can be rotated using a twisting tool, thus adjusting the tension of the torsion spring. Thereafter, the gear wheel shifted onto the guide tube with its receiving grooves is inserted again into the tooth-like projections of the partial regions of the end caps protruding from the lumen of the guide tube and fixed on the end cap by means of the mechanical fastening means. This mechanical fastening means also passes through the associated end region of the guide tube, so that in the final state the gear wheel, the end cap and the guide tube form a rotatable unit.

Aufgrund der Tatsache, daß das eine freie Ende der Torsionsfeder mit dem in das Lumen des Führungsrohres eingesetzten Endkappenstutzen und das andere freie Ende der Torsionsfeder an der Achse direkt befestigt sind, ist durch die geschilderte Bewegung der Endkappe mit dem Verdrehwerkzeug die Torsionsfeder gespannt worden bzw kann so gespannt werden, wie es für den vorgesehenen Verwendungszweck erforderlich ist.Due to the fact that the one free end of the torsion spring with the end cap socket inserted into the lumen of the guide tube and the other free end of the torsion spring are directly attached to the axle, the torsion spring has been or can be tensioned by the described movement of the end cap with the twisting tool be as excited as is necessary for the intended use.

In der Zeichnung ist ein Ausführungsbeispiel des erfindungsgemäßen Rolladenaufbaus schematisch dargestellt; es zeigt:

  • Fig. 1 den Rolladenaufbau nach der Erfindung in perspektivischer Teilansicht;
  • Fig. 2 einen Teilschnitt durch den linken Teilbereich gemäß Fig. 1.
In the drawing, an embodiment of the roller shutter structure according to the invention is shown schematically; it shows:
  • Figure 1 shows the roller shutter structure according to the invention in partial perspective view.
  • FIG. 2 shows a partial section through the left partial area according to FIG. 1.

In Fig. 1 ist die Seitenwand 1 im Schnitt gezeigt, die beispielsweise die Seitenwand eines Möbelstückes sein kann. An der oberen Kante der Seitenwand 1 ist die Rolladenführungsschiene 11 gezeigt, in der der Rolladen 2 beim Verschiebevorgang gleiten kann. Die Seitenwand 1 zeigt an ihrer Vorderkante die Rolladenführungsschiene 12, in die der Rolladen 2 eingelaufen ist.In Fig. 1, the side wall 1 is shown in section, which can for example be the side wall of a piece of furniture. On the upper edge of the side wall 1, the roller shutter guide rail 11 is shown, in which the roller shutter 2 can slide during the displacement process. The side wall 1 shows on its front edge the roller shutter guide rail 12 into which the roller shutter 2 has run.

Die in der Zeichnung nicht dargestellte gegenüberliegende Seitenwand ist mit entsprechenden Vorkehrungen ausgerüstet.The opposite side wall, not shown in the drawing, is equipped with appropriate precautions.

Das Führungsrohr 3 trägt an seinem der Seitenwand 1 zugewandten freien Ende das Zahnrad 4, welches über das mechanische Befestigungsmittel 41 durch das Führungsrohr 3 auf der Endkappe 5 festgelegt ist. Die Ausbildung der Endkappe 5 mit ihren aus dem Lumen des Führungsrohres herausragenden Teilbereichen 51 ist am gegenüberliegenden freien Ende des Führungsrohres 3 sichtbar. Die Teilbereiche 51 entsprechen mit ihrem äußeren Umfang exakt dem Umfang des Führungsrohres 3, so daß hier praktisch ein übergangsloser Anschluß zwischen den Teilbereichen 51 und dem Führungsrohr 3 geschaffen ist. Über den Umfang der Teilbereiche 51 und des Führungsrohres 3 stehen die zahnartigen Vorsprünge 511 vor, welche in ihren Abmessungen den in der Mittelbohrung 42 der Zahnräder 4 ausgeformten Aufnahmenuten 421 entsprechen. Das zugeordnete Zahnrad 4 ist durch Lösen des mechanischen Befestigungsmittels 41 in Pfeilrichtung über den Umfang des Führungsrohres zum anderen Zahnrad 4 hin verschoben, so daß die zahnartigen Vorsprünge 511 aus den Aufnahmenuten 421 herausgezogen worden sind. Durch das Lösen des mechanischen Befestigungsmittels 41 ist die Endkappe 5 über den sechskantigen Fortsatz 52 und ein in der Zeichnung nicht dargestelltes Verdrehwerkzeug innerhalb des Führungsrohres verdrehbar. Mit dieser Verdrehung wird die in Fig. 2 im Teilschnitt gezeigte Torsionsfeder 7 in ihrem Spannungsverhältnis entsprechend eingestellt. Aus der Endkappe 5 ragt die Achse 6 hervor, die über ihr Vierkantende 61 mit einer entsprechenden Halterung an der zugeordneten Seitenwand - in der Zeichnung nicht dargestellt - verdrehgesichert verbunden ist.The guide tube 3 carries at its free end facing the side wall 1 the gear 4, which is fixed on the end cap 5 by the guide tube 3 via the mechanical fastening means 41. The formation of the end cap 5 with its partial regions 51 protruding from the lumen of the guide tube is visible at the opposite free end of the guide tube 3. The partial areas 51 correspond with their outer circumference exactly to the circumference of the guide tube 3, so that here a practically seamless connection between the partial areas 51 and the guide tube 3 is created. The tooth-like projections 511 protrude over the circumference of the partial regions 51 and the guide tube 3, and their dimensions correspond to the receiving grooves 421 formed in the central bore 42 of the gear wheels 4. The assigned gear 4 is displaced in the direction of the arrow over the circumference of the guide tube to the other gear 4 by loosening the mechanical fastening means 41, so that the tooth-like projections 511 have been pulled out of the receiving grooves 421. By loosening the mechanical fastening means 41, the end cap 5 can be rotated within the guide tube via the hexagonal extension 52 and a twisting tool, not shown in the drawing. With this rotation, the torsion spring 7 shown in FIG. 2 in partial section is adjusted accordingly in its tension ratio. The axis 6 protrudes from the end cap 5, which is connected via its square end 61 to a corresponding holder on the associated side wall - not shown in the drawing - in a manner secured against rotation.

In Fig. 2 ist im Teilschnitt der linke Teilbereich gemäß Fig. 1 dargestellt. Die Seitenwand 1 zeigt eine Wellenaufnahme 13, in deren Vierkantöffnung das entsprechend ausgebildete Vierkantende 61 der Achse 6 eingreift. Im Anschluß an das Vierkantende 61 der Achse 6 ist die Endkappe 5 auf der Achse angeordnet und über dieser Endkappe 5 sitzt das Zahnrad 4.FIG. 2 shows the left section according to FIG. 1 in partial section. The side wall 1 shows a shaft receptacle 13, in the square opening of which the correspondingly formed square end 61 of the axis 6 engages. Following the square end 61 of the axis 6, the end cap 5 is arranged on the axis and the gear wheel 4 sits over this end cap 5.

Der zahnartige Vorsprung 511 der Endkappe 5 ist dabei im Eingriff in die Aufnahmenut 421 des Zahnrades 4 gezeigt. Im gegenüberliegenden Außenbereich des Teilschnitts ist das mechanische Befestigungsmittel 41 angedeutet, über welches das Zahnrad 4 durch das Führungsrohr 3 mit der Endkappe 5 verbunden ist.The tooth-like projection 511 of the end cap 5 is shown in engagement with the receiving groove 421 of the gear 4. In the opposite outer region of the partial section, the mechanical fastening means 41 is indicated, via which the gear wheel 4 is connected to the end cap 5 by the guide tube 3.

Im oberen Bereich der Darstellung ist innerhalb des Führungsrohres das freie Ende 71 der Torsionsfeder 7 im Einsatz in den Endkappenstutzen 53 gezeigt. Über ein mechanisches Befestigungsmittel 72 ist das freie Ende 71 der Torsionsfeder 7 mit der Endkappe 5 und dem Führungsrohr 3 fest verbunden. Die Torsionsfeder 7 verläuft mit ihren Windungen über die Achse 6 bis zu dem Punkt der Anlenkung 62. In der gezeigten Darstellung ist dieser Punkt der Anlenkung 62 eine Bohrung durch die Achse 6, durch die das freie Ende 73 der Torsionsfeder 7 durchgezogen ist. Das freie Ende 73 der Torsionsfeder 7 ist dann beispielsweise über der Achse 6 abgebogen und auf diese Weise festgelegt. Im Bedarfsfall kann dieses Festlegen durch aus dem Stand der Technik bekannte Mittel wie Kleben, Schweißen, Schrauben usw. unterstützt werden.In the upper area of the illustration, the free end 71 of the torsion spring 7 is shown in use in the end cap stub 53 within the guide tube. The free end 71 of the torsion spring 7 is firmly connected to the end cap 5 and the guide tube 3 via a mechanical fastening means 72. The torsion spring 7 runs with its windings over the axis 6 to the point of the articulation 62. In the illustration shown, this point of the articulation 62 is a bore through the axis 6 through which the free end 73 of the torsion spring 7 is pulled.
