Description

Die Erfindung betrifft einen Rolladen mit einer drehbar gelagerten, selbstsperrenden Wickelwelle und einem auf dieser aufwickelbaren Rolladenpanzer aus mehreren gelenkig miteinander verbundenen Rolladenelementen, wobei das oberste Rolladenelement mit der Wickelwelle verbunden ist, wobei an der Wickelwelle ein erster, in axialer Richtung der Wickelwelle verlaufender Verbindungsabschnitt ausgebildet ist und am obersten Rollladenelement ein zweiter, in axialer Richtung der Wickelwelle verlaufender Verbindungsabschnitt ausgebildet ist.The invention relates to a roller shutter with a rotatable stored, self-locking winding shaft and one this roll-up roller shutter curtain from several roller shutter elements articulated together, the top roller shutter element with the winding shaft is connected, wherein on the winding shaft a first, in Connecting section extending in the axial direction of the winding shaft is formed and on the top roller shutter element a second, in the axial direction of the Connection shaft extending winding shaft formed is.

Es sind bereits verschiedenste Maßnahmen bekannt, um die Einbruchsicherheit von Rolläden zu erhöhen. Eine Maßnahme besteht darin, eine selbstsperrende Wickelwelle vorzusehen, die beispielsweise über ein selbsthemmendes Schneckengetriebe nur über eine Handkurbel oder einen Motor drehbar ist, die aber bei abgeschaltetem Motor bzw. Ruhen der Handkurbel nicht durch Angriff an der Wickelwelle selbst verdreht werden kann. Zusammen mit einer geeigneten Ausbildung der obersten, üblicherweise in einem Rolladenkasten untergebrachten Rolladenelemente kann damit ein unbefugtes Hochschieben des Rolladenpanzers vermieden werden. Eine Schwachstelle war bisher aber die Befestigung des obersten Rolladenelementes an der Ausziehwelle, die bisher über Schrauben oder Nieten erfolgt ist. Nach Öffnen des Rolladenkastens war es damit einem Einbrecher mit relativ einfachen Werkzeugen möglich, das oberste Rolladenelement von der Wickelwelle zu lösen und damit trotz gesperrter Wickelwelle den Rolladenpanzer hochzuziehen. Various measures are already known to to increase the security against burglary of roller shutters. A Measure is a self-locking winding shaft to provide, for example, a self-locking Worm gear only via a hand crank or a motor is rotatable, but which is switched off Motor or rest of the hand crank not by attack can be rotated on the winding shaft itself. Together with a suitable education of the top, usually housed in a roller shutter box Roller shutter elements can thus be pushed up by unauthorized persons of the roller shutter curtain can be avoided. A vulnerability So far, however, was the attachment of the top Roller shutter element on the pull-out shaft, which was previously used Screws or rivets is done. After opening the The shutter box was there with a burglar relatively simple tools possible, the top one To release the shutter element from the winding shaft and thus pulling up the roller shutter curtain despite the winding shaft being locked.

Die FR-A 1 266 581 beschreibt bereits einen Rolladen, bei dem die Wickelwelle einen nutförmigen Verbindungsabschnitt aufweist, um den ein hakenförmiger Verbindungsabschnitt des obersten Rolladenelementes eingehängt ist. Die Montage des Rolladenvorhanges in der Wickelwelle ist denkbar einfach. Es braucht nur das hakenförmige Element am obersten Rolladenelement in die Nut der Wickelwelle eingehängt werden. Genauso einfach wie die Montage ist aber für einen Einbrecher ein Aushängen des obersten Rolladenelementes aus der Nut der Wickelwelle. Es ist somit für den Einbrecher nach Öffnen des üblichen Rolladenkastens leicht möglich, das oberste Rolladenelement auszuhängen und den gesamten Rolladenvorhang hochzuziehen.FR-A 1 266 581 already describes a roller shutter, in which the winding shaft has a groove-shaped connecting section around which a hook-shaped connecting section of the top roller shutter element is. The assembly of the roller shutter curtain in the Winding shaft is very simple. It only needs that hook-shaped element on the top roller shutter element in the Slot in the winding shaft. Just as easy like assembly, a burglar is unhinged the top roller shutter element from the groove of Winding shaft. It is after for the burglar Opening the usual roller shutter box easily possible unhook the top roller shutter element and the entire Pull up the roller shutter curtain.

Aufgabe der Erfindung ist es, einen Rolladen der eingangs genannten Gattung zu schaffen, der eine erhöhte Einbruchsicherheit aufweist.The object of the invention is to provide a roller shutter at the beginning to create named genus, which increased Burglar-proof.

Dies wird erfindungsgemäß dadurch erreicht, daß ein Verbindungsabschnitt den anderen zum Zusammenhalten von Wickelwelle und oberstem Rolladenelement - vorzugsweise mit Spiel - derart formschlußartig umfaßt, daß ein Herausnehmen des obersten Rolladenelementes aus der Wickelwelle in jeder Richtung senkrecht zur Achse der Wickelwelle unmöglich ist.This is achieved in that a Connecting section the other to hold together Winding shaft and top roller shutter element - preferably with play - so form-fitting that a Removing the top roller shutter element from the Winding shaft in any direction perpendicular to the axis of the Winding shaft is impossible.

Unter einer formschlußartigen Verbindung wird im Sinne der Erfindung eine Verbindung zweier Teile (hier der Wickelwelle und des obersten Rolladenelementes) verstanden, bei der der Zusammenhalt der beiden Teile durch die Form der beiden ineinandergreifenden Teile bestimmt ist, ohne daß zusätzliche Verbindungsmittel wie Schrauben, Nieten oder dergleichen nötig wären. Die erfindungsgemäße formschlußartige Verbindung hält die beiden Teile (Wickelwelle und oberstes Rolladenelement) unverlierbar zusammen, kann aber im Gegensatz zum Formschluß im engeren Sinne, bei dem die beiden Teile durch korrespondierende Ausbildung im wesentlichen unbeweglich miteinander verbunden sind auch eine zumindest begrenzte Relativbewegung der beiden Teile erlauben.Under a form-fitting connection is in the sense the invention a connection of two parts (here the Understood winding shaft and the top roller shutter element), where the cohesion of the two parts through the shape of the two interlocking parts is determined without additional connecting means such as screws, rivets or the like would be necessary. The Form-locking connection according to the invention holds the two parts (winding shaft and top roller shutter element) captive together, but can, in contrast to form locking in the narrower sense, in which the two parts by corresponding training essentially immobile at least one another is connected allow limited relative movement of the two parts.

Beim Zusammenbau des erfindungsgemäßen Rolladens können die beiden Verbindungsabschnitte einfach in axialer Richtung ineinander geschoben werden und halten dann formschlußartig zusammen, wobei in jeder auf die Wickelwelle senkrechten Richtung ein Herausnehmen des obersten Rolladenelementes aus der Wickelwelle unmöglich ist. Da bei am Einsatzort eingebauter Wickelwelle ein axiales Herausschieben des obersten Rolladenelementes nicht möglich ist und andererseits keine lösbaren Befestigungselemente wie Schrauben, Nieten oder dergleichen vorgesehen sind, kann das oberste Rolladenelement nicht von der Wickelwelle getrennt werden, womit es dem Einbrecher unmöglich ist, den Rolladen hochzuziehen.When assembling the roller shutter according to the invention can the two connecting sections simply in axial Towards each other and then stop form-fitting together, in each on the Winding shaft vertical direction taking out top roller shutter element from the winding shaft impossible is. As with the winding shaft installed on site an axial pushing out of the top roller shutter element is not possible and on the other hand no detachable Fastening elements such as screws, rivets or the like are provided, the top roller shutter element not be separated from the winding shaft, with what it is impossible for the burglar to pull up the roller shutters.

Gegenstand der Erfindung ist auch der Rolladen nach Anspruch 3. Besondere Ausführungsarten sind in den abhängigen Ansprüchen angegeben.The invention also relates to the roller shutter according to claim 3. Special embodiments are specified in the dependent claims.

Weitere Vorteile und Einzelheiten der Erfindung werden in der nachfolgenden Figurenbeschreibung näher erläutert.Further advantages and details of the invention will be explained in more detail in the following description of the figures.

Es zeigen die Fig. 1 einen Querschnitt durch ein Ausführungsbeispiel des erfindungsgemäßen Rolladens bei herabgelassenem Rolladen (gesperrter Zustand), die Fig. 2 einen Querschnitt durch ein zweites Ausführungsbeispiel bei herabgelassenem Rolladen (gesperrter Zustand) und die Fig. 3 einen Querschnitt durch das in Fig. 2 gezeigte Ausführungsbeispiel bei teilweise aufgewickeltem Rolladenpanzer. 1 shows a cross section through an embodiment of the roller shutter according to the invention lowered roller shutter (locked state), the Fig. 2 shows a cross section through a second exemplary embodiment with shutters lowered (locked state) and FIG. 3 shows a cross section through that in FIG. 2 shown embodiment with partially wound Roller shutter curtain.

Der in Fig. 1 dargestellte Rolladen umfaßt eine in einem Rolladenkasten 1 um eine Achse 2 drehbar gelagerte Wickelwelle 3, welche selbstsperrend ist, das heißt bei ruhendem Antriebsmotor bzw. Antriebskurbel von außen nicht verdrehbar ist. Dies läßt sich beispielsweise mit einem Schneckengetriebe (nicht dargestellt) erreichen. Die Fig. 1 zeigt den aus gelenkig miteinander verbundenen Rolladenelementen 4a, 4 bestehenden Rolladenpanzer in herabgelassenem Zustand. Die Rolladenelemente 4 unterhalb des Rolladenkastens 1 sind in zwei seitlichen Führungsschienen 7 geführt. Unten weist der Rolladenpanzer ein mit einer Stahleinlage versehenes Endprofil 5 auf, welches an seiner Unterseite Dichtleisten 6 aus elastischem Material aufweist.The roller shutter shown in Fig. 1 comprises a in a roller shutter box 1 rotatably mounted about an axis 2 Winding shaft 3, which is self-locking, that means when the drive motor or drive crank is stationary is not rotatable from the outside. This can be done, for example with a worm gear (not shown) to reach. Fig. 1 shows the articulated interconnected shutter elements 4a, 4 existing Roller shutter curtain in lowered condition. The Roller shutter elements 4 are below the roller shutter box 1 guided in two lateral guide rails 7. Below the roller shutter has a steel insert provided end profile 5, which on its underside Sealing strips 6 made of elastic material.

Erfindungsgemäß ist das oberste Rolladenelement 4a ohne Befestigungsmittel wie Schrauben, Nieten oder dergleichen formschlußartig mit der Wickelwelle 3 verbunden. Dazu weist diese einen als Nut 8 ausgebildeten ersten Verbindungsabschnitt auf, der sich in axialer Richtung der Wickelwelle erstreckt. Das oberste Rolladenelement weist einen durch einen profilierten Längskantenabschnitt gebildeten zweiten Verbindungsabschnitt 9 auf. Die Nut 8 ist nach innen erweitert und der Verbindungsabschnitt 9 des obersten Rolladenelementes 4a weist in erweitertem Bereich der Nut 8 eine größere Querabmessung auf als die schlitzförmige äußere Nutöffnung 8a. Damit kann das oberste Rolladenelement 4a bei eingebauter Wickelwelle nicht aus dieser herausgenommen werden. Das oberste Rolladenelement 4a kann beim Zusammenbau des Rolladens leicht in axialer Richtung in die Nut eingeschoben werden. Wenngleich - wie bereits erwähnt - bei eingebautem Rolladen ein axiales Herausschieben des obersten Rolladenelementes 4a in praktisch allen Anwendungsfällen nicht möglich ist, so kann für Sondereinbauten eine zusätzliche Sicherung (beispielsweise Stifte, Splinte oder dgl.) gegen axiales Verschieben des obersten Rolladenelementes 4a vorgesehen sein.According to the top roller shutter element 4a is without Fasteners such as screws, rivets or the like positively connected to the winding shaft 3. For this purpose, this has a first designed as a groove 8 Connection section on, which is in the axial direction the winding shaft extends. The top roller shutter element has a through a profiled longitudinal edge portion formed second connection section 9. The groove 8 is expanded inwards and the connecting section 9 of the top roller shutter element 4a points in expanded area of the groove 8 a larger transverse dimension than the slot-shaped outer groove opening 8a. So that the top roller shutter element 4a when installed Winding shaft cannot be removed from this. The top roller shutter element 4a can be assembled the roller shutter slightly in the axial direction into the groove be inserted. Although - as already mentioned - when the roller shutter is installed, the top roller shutter element 4a in practically all applications is not possible, so for special installations an additional backup (for example Pins, split pins or the like) against axial displacement of the uppermost roller shutter element 4a.

Die die Nut 8 begrenzenden Wände können einstückig mit der Wickelwelle ausgebildet sein, um einen stabilen Halt für das oberste Rolladenelement 4a bereitzustellen. Vorteilhaft kann die Wickelwelle als ein hohles stranggepreßtes Aluminiumprofil ausgebildet sein, welches verhältnismäßig leicht herzustellen und auf beliebige Längen ablängbar ist.The walls delimiting the groove 8 can be made in one piece with the winding shaft to be designed to a stable Provide support for the top roller shutter element 4a. The winding shaft can advantageously be a hollow one extruded aluminum profile, which relatively easy to manufacture and on any Lengths can be cut to length.

Um einerseits ein platzsparendes Aufwickeln des Rolladenpanzers auf die Wickelwelle zu ermöglichen und andererseits eine Sperrfunktion gegen unzulässiges Hochschieben des Rolladenpanzers zu erzielen, ist das oberste Rolladenelement 4a vorzugsweise schwenkbar an der Wickelwelle 3 gelagert. Das oberste Rolladenelement 4a und die Wickelwelle 3 ist so profiliert, daß das oberste Rolladenelement ausgehend von einer am Umfang der Wickelwelle anliegenden Stellung (aufgewickelter Rolladen wie beispielsweise in Fig. 3) nur bis zu einem Sperrwinkel a von der Wickelwelle wegschwenkbar ist. Nachdem das unterste Rolladenelement 5 unten aufsetzt, kann die Wickelwelle 3 noch etwas im Uhrzeigersinn weitergedreht werden, bis die in Fig. 1 dargestellte Stellung erreicht ist, bei der das oberste Rolladenelement 4a maximal von der Wickelwelle weggeschwenkt ist, also unter dem Sperrwinkel α von der Wickelwelle 3 absteht. In dieser Stellung kann das oberste Rolladenelement 4a nicht mehr weiter nach oben geschwenkt werden. Da die Wickelwelle 3 selbstsperrend ist, kann auch diese nicht mehr entgegen dem Uhrzeigersinn verdreht werden, sodaß ein unbefugtes Hochschieben des Rolladenpanzers nicht möglich ist. On the one hand, space-saving winding of the roller shutter curtain on the winding shaft and on the other hand a locking function against inadmissible pushing up to achieve the shutter curtain is the top one Roller shutter element 4a preferably pivotable on the Winding shaft 3 mounted. The top roller shutter element 4a and the winding shaft 3 is profiled so that the top one Roller shutter element starting from one on the circumference of the Position of the winding shaft (wound roller shutter as for example in Fig. 3) only up to one Locking angle a is pivotable away from the winding shaft. After the bottom roller shutter element 5 touches down, the winding shaft 3 can be turned slightly clockwise until the position shown in Fig. 1 is reached at which the top roller shutter element 4a is maximally pivoted away from the winding shaft, that is protrudes from the winding shaft 3 at the locking angle α. In this position, the top roller shutter element 4a can no longer be pivoted upwards. Since the Winding shaft 3 is self-locking, this can not be turned more counterclockwise so that an unauthorized pushing up of the shutter curtain is not is possible.

Das oberste Rolladenelement 4a übt also eine Sperrfunktion aus. Da es immer im Rolladenkasten verbleibt, kann es anders ausgebildet sein, als die bei herabgelassenem Rolladen sichtbaren vorzugsweise hohlprofiligen Rolladenelemente. Insbesondere kann das oberste Rolladenelement ein sich über die gesamte Länge der Wickelwelle erstreckendes lamellenartiges Sperrprofil sein, dessen eine profilierte Längskante mit der Wickelwelle verbunden ist und dessen andere profilierte Längskante gelenkig mit dem nächsten Rolladenelement 4 in Verbindung steht. Ein solches im Querschnitt vorteilhaft gekrümmtes Sperrprofil hält hohen Krafteinwirkungen stand und kann sich wie in Fig. 3 gezeigt, im aufgewickelten Zustand platzsparend an die Umfangfläche der Wickelwelle 3 anlegen. Das Sperrprofil 4a kann vorzugsweise ebenfalls aus Aluminium bestehen.The uppermost roller shutter element 4a therefore exercises a locking function out. Since it always remains in the roller shutter box, it can it can be designed differently than that with lowered Roller shutters visible preferably hollow profile roller shutter elements. In particular, the top roller shutter element one over the entire length of the winding shaft extending slat-like locking profile, the a profiled longitudinal edge connected to the winding shaft and its other profiled longitudinal edge is articulated with the next roller shutter element 4 in connection stands. Such an advantageously curved in cross section Locking profile withstands high forces and can, as shown in Fig. 3, in the wound state space-saving on the peripheral surface of the winding shaft 3 create. The locking profile 4a can preferably also are made of aluminum.

Zusätzlich zur Sperrfunktion, die dadurch gegeben ist, daß das oberste Rolladenelement 4a (Sperrprofil) nur in einem beschränkten Winkelbereich gegenüber der Wickelwelle 3 verschwenkbar ist, kann eine Sperrwirkung dadurch erzielt werden, daß das oberste Rolladenelement 4a mit der der Wickelwelle 3 abgewandten Längskante 10 an der Innenwand des Rolladenkastens 1 anliegt.In addition to the locking function, which is given by that the top roller shutter element 4a (locking profile) only in a limited angular range with respect to the winding shaft 3 is pivotable, can have a locking effect achieved that the top roller shutter element 4a with the longitudinal edge 10 facing away from the winding shaft 3 abuts the inner wall of the roller shutter box 1.

Das in den Fig. 2 und 3 dargestellte Ausführungsbeispiel unterscheidet sich von dem in Fig. 1 dargestellten Ausführungsbeispiel im wesentlichen durch einen größeren Rolladenkasten 1 zur Aufnahme eines höheren Rolladenpanzers und durch die Tatsache, daß am Sperrprofil 4a (oberstes Rolladenelement) noch ein weiteres gleichartiges Sperrprofil 4b schwenkbar gelagert ist. The embodiment shown in FIGS. 2 and 3 differs from that shown in Fig. 1 Embodiment essentially by a larger roller shutter box 1 to accommodate a higher one Roller shutter curtain and due to the fact that the locking profile 4a (top roller shutter element) yet another the same locking profile 4b is pivotally mounted.

Die Fig. 2 zeigt den gesperrten Zustand, bei dem ein unbefugtes Hochschieben des Rolladenpanzers unmöglich ist. Dabei kommt das Merkmal zum Tragen, daß das zweite Rolladenelement (Sperrprofil 4b) gegenüber dem ersten nur bis zu einem Sperrwinkel von etwa 180° aufschwenkbar ist. Die an der äußeren Längskante des obersten Rolladenelementes 4a vorgesehene Nut 8' kann dabei im wesentlichen gleich ausgebildet sein, wie die in der Wickelwelle 3 integrierte Nut 8. Auch die Teile 4a und 4b sind formschlußartig im Sinne der Erfindung miteinander verbunden und können daher bei eingebautem Rolladen nicht voneinander getrennt werden.Fig. 2 shows the locked state in which a unauthorized pushing up of the roller shutter curtain impossible is. The feature that comes into play here is that the second Roller shutter element (locking profile 4b) compared to the first can only be swung open up to a locking angle of approximately 180 ° is. The one on the outer long edge of the top Roller shutter element 4a provided groove 8 'can be designed essentially the same as that in the Winding shaft 3 integrated groove 8. Also parts 4a and 4b are interlocking in the sense of the invention connected and can therefore with built-in roller shutters not be separated from each other.

Die Fig. 3 zeigt den Wickelvorgang und insbesondere wie sich die schlanken Sperrprofile 4a und 4b platzsparend an die Umfangsfläche der Wickelwelle 3 legen.3 shows the winding process and in particular how the slim locking profiles 4a and 4b save space place on the peripheral surface of the winding shaft 3.

Die Erfindung ist nicht auf die dargestellten Ausführungsbeispiele beschränkt. Beispielsweise könnte das oberste Rolladenelement 4a sich nicht über die ganze Länge der Wickelwelle erstrecken (wenngleich dies aus herstellungs- und festigkeitstechnischen Gründen vorteilhaft erscheint). Es wäre beispielsweise auch denkbar, daß das oberste Rolladenelement 4a und gegebenenfalls daran angeschlossene weitere Rolladenelemente jeweils aus zwei oder mehreren axial beabstandeten Rolladenelementteilen besteht, an denen der eigentliche Rolladenpanzer aufgehängt ist. Bei den dargestellten Ausführungsbeispielen weist die Wickelwelle eine Nut auf, in der das oberste Rolladenelement 4a formschlußartig gehalten ist. Es wäre jedoch auch denkbar, daß beispielsweise die Nut am obersten Rolladenelement ausgebildet ist und einen von der Wickelwelle abstehenden Vorsprung oder dergleichen formschlußartig umfaßt, um die Wickelwelle und das oberste Rolladenelement einbruchsicher miteinander zu verbinden.The invention is not based on the illustrated embodiments limited. For example, that top roller shutter element 4a not over the whole Extend the length of the winding shaft (albeit from manufacturing and strength reasons advantageous appears). For example, it would also be conceivable that the top roller shutter element 4a and possibly connected further roller shutter elements each from two or more axially spaced roller shutter element parts exists on which the actual shutter armor is hung. In the illustrated embodiments the winding shaft has a groove, in which the top roller shutter element 4a form-fitting is held.
