Abstract

The roller shutter (18), with slats (19), rides in guide rails (1) on both sides at the wall surfaces facing the window opening. The roll drum (17) rides on bearings (16) at both sides, on bearing mountings (3) attached to the guide rails by straps (4). The upper end of the shutter is attached to the winding drum by leaf springs (21). Limit stops (7) are fitted to the bearing carriers, over the winding drum, on a projection of the plane through a lowered shutter so that, if the shutter is pushed upwards, the upper end of the shutter slides through the leaf springs against the limit stops so that a forced entry is prevented.

Description

Die vorliegende Erfindung bezieht sich auf einen Rollladen mit zwei seitlichen, in der Laibung einer Gebäudeöffnung befestigbaren Führungsschienen und einer beidseitig in Lagern drehbar getragenen Wickeltrommel, auf welche der Rollladen, der aus miteinander über Gelenkmittel verbundenen Lamellen gebildet ist, aufwickelbar und abwickelbar ist und das der Wickeltrommel zugewandte obere Ende des Rollladens über Federblätter mit der Wickeltrommel verbunden ist, wobei jedes Lager an einem Lagerträger befestigt ist, der jeweils über eine Lasche mit der Führungsschiene verbunden ist.The present invention relates to a roller shutter with two lateral, attachable in the soffit of a building opening guide rails and a rotatably supported on both sides winding rotations drum, on which the shutter, which is formed by joint means connected to slats, wound and unwound and the Winding drum facing upper end of the shutter is connected via spring leaves with the winding drum, each bearing is fixed to a bearing support, which is connected in each case via a tab to the guide rail.

Derartige Rollladen sind bekannt. So zeigt beispielsweise die EP-A-1 203 865 einen derartigen Rollladen, bei welchem die Montage und Demontage der Wickeltrommel und der beiden Lager sehr einfach ist. Zusätzlich sind die Lager an den Führungsschienen des Rollladens befestigt, was sich insbesondere bei beschränkten Platzverhältnissen zum Unterbringen des Rollladens als vorteilhaft erweist.Such blinds are known. For example, shows the EP-A-1 203 865 Such a roller shutter, in which the assembly and disassembly of the winding drum and the two bearings is very simple. In addition, the bearings are attached to the guide rails of the shutter, which proves to be particularly in limited space for accommodating the shutter to be beneficial.

Derartige Rollladen sollen zudem einen Schutz gegen gewaltsames Öffnen der entsprechenden Gebäudeöffnung, insbesondere Fenster bieten, wobei insbesondere ein Anheben des Rollladens auch mit grossem Kraftaufwand nach Möglichkeit verhindert werden soll. Hierzu werden verschiedenste Lösungen angeboten, beispielsweise können die unteren Enden der Rollladen mit Verriegelungseinrichtungen ausgestattet sein, mit welchen die Rollladen in der heruntergelassenen Position verriegelt sind. Diese Verriegelungseinrichtungen sind, insbesondere wenn sie automatisch beim Erreichen der unteren Position des Rollladens verriegelt werden sollen, relativ aufwendig in der Herstellung und somit entsprechend teuer. Zusätzlich erfordern viele derartiger Verriegelungseinrichtungen ein manuelles Entriegeln, bevor der Rollladen hochgezogen werden soll, was sich negativ auf die Bedienerfreundlichkeit auswirkt.Such blinds should also provide protection against violent opening of the corresponding building opening, in particular windows, in particular, a lifting of the shutter should be prevented with great effort, if possible. For this purpose, a variety of solutions are offered, for example, the lower ends of the blinds can be equipped with locking devices with which the blinds are locked in the lowered position. These locking devices are, especially if they are to be automatically locked when reaching the lower position of the shutter, relatively expensive to manufacture and thus correspondingly expensive. In addition, many such locking devices require manual unlocking before the roller shutter is to be pulled up, which has a negative impact on user-friendliness.

Die Aufgabe der vorliegenden Erfindung besteht nun darin, einen Rollladen so auszugestalten, dass mit einfachen Mitteln erreicht werden kann, dass ein gewaltsames Anheben des Rollladens bei geschlossener Position praktisch verunmöglicht wird, auch wenn dies mit relativ grossem Kraftaufwand versucht wird.The object of the present invention is to design a roller shutter so that can be achieved by simple means that a violent lifting of the shutter in the closed position practically impossible, even if this is attempted with relatively great effort.

Erfindungsgemäss erfolgt die Lösung dieser Aufgabe dadurch, dass an den Lagerträgern Anschlagelemente angebracht sind, die oberhalb der Wickeltrommel in die Ebene, welche durch den heruntergelassenen und in den Führungsschienen gehaltenen Rollladen gebildet ist, vorstehend sind, und dass beim Hochdrücken des heruntergelassenen Rollladens das obere Ende des Rollladens, geleitet durch die Federblätter, an diesen Anschlagelementen zur Anlage kommt.According to the invention, the solution of this object is achieved in that on the bearing supports stop elements are mounted above the winding drum in the plane which is formed by the lowered and held in the guide rails roller shutter, are prominent, and that when pushing up the lowered shutter the upper end of the shutter, passed through the spring leaves, comes to these stop elements to the plant.

Mit dieser erfindungsgemässen Lösung wird in einfachster Weise erreicht, dass der Rollladen, sobald das obere Ende des Rollladens an diesen Anschlagelementen anliegt, nicht mehr weiter angehoben werden kann.With this inventive solution is achieved in the simplest way that the shutter, as soon as the upper end of the shutter rests against these stop elements can not be raised further.

Einen besonders einfachen Aufbau erhält man dadurch, dass die Laschen am aussenseitigen Führungsbereich der Führungsschienen befestigt sind und dass die Anschlagelemente an einer über die Lagerträger hinausragenden Verlängerung der Lasche angebracht sind. Diese Ausgestaltung lässt sich sehr kostengünstig herstellen.A particularly simple structure is obtained by the fact that the tabs are attached to the outside guide portion of the guide rails and that the stop elements are mounted on a projecting beyond the bearing bracket extension of the tab. This embodiment can be produced very inexpensively.

In vorteilhafter Weise ist die Lasche, der Lagerträger und die Verlängerung der Lasche aus einem abgewinkelten plattenförmigen Element gebildet, bei welchem die Lasche und die Verlängerung der Lasche die Abwinkelung bilden. Dies ermöglicht eine einfache und kostengünstige Herstellung.Advantageously, the tab, the bearing carrier and the extension of the tab is formed from an angled plate-shaped element, wherein the tab and the extension of the tab form the bend. This allows a simple and inexpensive production.

Der Anschlag kann in besonders einfacher Weise dadurch erzeugt werden, indem der der Lasche abgewandte Endbereich der Verlängerung hakenförmig umgebogen ist.The stop can be produced in a particularly simple manner by the end region of the extension facing away from the tab is bent like a hook.

In vorteilhafter Weise sind die oberen Lamellen des Rollladens mit Mitteln ausgestattet, welche ein Ausknicken der Lamellen um die Gelenkmittel gegen die Wickelrolle hin verhindern. Durch dieses Verhindern des Ausknickens der Lamellen gegen die Wickelrolle hin wird eine erhöhte Stabilität erreicht, auch beim Versuch des Anhebens des Rollladens mit grossem Kraftaufwand gelingt es nicht, die oberen Lamellen des Rollladens, die nicht in den Führungsschienen gehalten sind, zum Ausknicken zu bewegen.Advantageously, the upper slats of the shutter are equipped with means which prevent buckling of the slats around the hinge means against the winding roll out. By preventing the buckling of the slats against the winding roll out increased stability is achieved, even when trying to lift the shutter with great effort It is not possible to cause the upper slats of the shutter, which are not held in the guide rails, to buckle.

In vorteilhafter Weise sind diese Ausknickmittel durch Stäbe gebildet, die jeweils in die Gelenkmittel der schwenkbar miteinander verbundenen Lamellen eingeschoben sind. Mit dieser sehr einfachen Anwendung können auch die bisher verwendeten Lamellen so ausgestattet werden, dass ein Ausknicken verunmöglicht wird.Advantageously, these Ausknickmittel are formed by rods which are respectively inserted into the hinge means of the pivotally interconnected slats. With this very simple application, the previously used slats can be equipped so that a buckling is impossible.

In vorteilhafter Weise ist der Lagerträger jeweils mit Schlitzen versehen, an welchen ein zusätzliches Winkelstück einstellbar befestigbar ist, mit welchem der jeweilige Lagerträger zusätzlich am Rahmen der Gebäudeöffnung befestigbar ist. Dadurch kann eine zusätzliche Stabilität erreicht werden.Advantageously, the bearing carrier is provided in each case with slots to which an additional angle piece can be fixed in an adjustable manner, with which the respective bearing carrier can additionally be fastened to the frame of the building opening. As a result, additional stability can be achieved.

Eine weitere vorteilhafte Ausgestaltung der Erfindung besteht darin, dass in einem unteren Schlitz der jeweiligen Lagerträger jeweils eine Lagerung für eine Wickelrolle eines Fliegengitters anbringbar ist. Dadurch kann dieses Fliegengitter in einfacher und optimaler Weise im Kasten, in welchem der Rollladen angeordnet ist, ebenfalls untergebracht werden.A further advantageous embodiment of the invention is that in each case a storage for a winding roll of a fly screen is attachable in a lower slot of the respective bearing carrier. As a result, this fly screen can be housed in a simple and optimal manner in the box in which the shutter is located.

In vorteilhafter Weise ist die Lagerung jeweils mit einer Abdeckung versehen, die so ausgebildet ist, dass sie als Führungshilfe für den Einlauf der Lamellen des Rollladens in die jeweilige Führungsschiene dient. Dadurch kann in einfacher Weise mit der entsprechenden Abdeckung eine zusätzliche notwendige Funktion ausgeübt werden.Advantageously, the storage is in each case provided with a cover which is designed so that it serves as a guide for the inlet of the slats of the shutter in the respective guide rail. As a result, an additional necessary function can be exercised in a simple manner with the corresponding cover.

In vorteilhafter Weise sind längs der Führungsschienen weitere Führungen angebracht, welche der Führung des Fliegengitters dienen. Diese weiteren Führungen sind somit in unauffälliger Weise praktisch in die Führungsschienen des Rollladens integriert.Advantageously, further guides are attached along the guide rails, which serve to guide the fly screen. These other guides are thus integrated in an inconspicuous manner practically in the guide rails of the shutter.

Eine Ausführungsform der vorliegenden Erfindung wird nachfolgend anhand der beiliegenden Zeichnung beispielhaft näher erläutert.An embodiment of the present invention will now be described by way of example with reference to the accompanying drawings.

Hierbei ist die Lasche 4 aussenseitig am äusseren Schenkel 8 der U-förmig ausgebildeten Führungsschiene befestigt. Die Befestigung könnte auch innenseitig am äusseren Schenkel 8 der Führungsschiene vorgenommen werden.In the illustrated embodiment, the connection between the guide rail 1 and the angled plate-shaped element 2 is formed by a head bolt, but this connection can also be formed by screws or rivets. Here, the tab 4 is attached to the outside of the outer leg 8 of the U-shaped guide rail. The attachment could also be made on the inside of the outer leg 8 of the guide rail.

Der Lagerträger 3 weist einen breiten Schlitz 9 auf, welcher etwa mittig angebracht ist und nach hinten offen ist. In diesen breiten Schlitz 9 ist das Lager für die Wickeltrommel untergebracht und befestigt, wie später noch ersichtlich wird. Ferner ist der Lagerträger 3 mit Schlitzen 10 und 11 versehen, mittels welchen ein zusätzliches Winkelstück 12 in bekannter Weise durch Verschraubung gehalten werden kann, wobei dieses Winkelstück 12 längs der Schlitze 10 und 11 einstellbar ist, und mit welchem Winkelstück 12 der Lagerträger 3 zusätzlich am Rahmen der Gebäudeöffnung angeschraubt werden kann. Dadurch ist der Lagerträger 3 nicht nur über die Führungsschiene 1 gehalten, sondern zusätzlich noch mit dem Rahmen der Gebäudeöffnung verbunden, wodurch sich eine grosse Stabilität ergibt.The bearing carrier 3 has a wide slot 9, which is mounted approximately centrally and is open to the rear. In this wide slot 9, the bearing for the winding drum is housed and secured, as will be seen later. Further, the bearing support 3 is provided with slots 10 and 11, by means of which an additional angle piece 12 can be held in a known manner by screwing, this angle piece 12 along the slots 10 and 11 is adjustable, and with which angle 12 of the bearing support 3 in addition to Frame of the building opening can be screwed. As a result, the bearing support 3 is not only held over the guide rail 1, but additionally connected to the frame of the building opening, resulting in a great stability.

Zusätzlich ist der Lagerträger 3 noch mit einem unteren Schlitz 13 versehen, in welchen noch zusätzliche Elemente untergebracht werden können, wie später noch gesehen wird.In addition, the bearing support 3 is still provided with a lower slot 13, in which additional elements can be accommodated, as will be seen later.

Wie aus den Fig. 2 bis 4 ersichtlich ist, ist die Führungsschiene 1 in bekannter Weise in der Laibung einer Gebäudeöffnung befestigt, derart, dass der Lagerträger 3 in einen am Gebäude ausgesparten Raum hineinragt, in welchem der Rollladen untergebracht ist. In bekannter Weise ist dieser Raum durch Abdeckungen 14 und 15 abgedeckt.Like from the Fig. 2 to 4 it can be seen, the guide rail 1 is fixed in a known manner in the reveal of a building opening, such that the bearing support 3 protrudes into a recessed space on the building, in which the shutter is housed. In known manner, this space is covered by covers 14 and 15.

Im breiten Schlitz 9 des Lagerträgers 3 ist das Lager 16 befestigt, welches das eine Ende einer Wickeltrommel 17 trägt, auf welche der Rollladen 18 aufwickelbar ist. Die Wickeltrommel 17 kann hierbei in bekannter Weise von Hand oder motorisch angetrieben werden.In the wide slot 9 of the bearing support 3, the bearing 16 is fixed, which carries the one end of a winding drum 17, on which the shutter 18 can be wound. The winding drum 17 can be driven in this case in a known manner by hand or by motor.

Der Rollladen 18 ist durch Lamellen 19 gebildet, die über Gelenkmittel 20 schwenkbar in bekannter Weise gegenseitig miteinander verbunden sind. Hierbei sind die Lamellen 19 beim Herunterlassen oder Hochziehen des Rollladens 18 in der Führungsschiene 1 geführt. Selbstverständlich ist eine entsprechende Lageranordnung für die Wickeltrommel, wie sie vorgängig beschrieben worden ist, auch auf der gegenüberliegenden Seite der Gebäudeöffnung vorgesehen.The shutter 18 is formed by fins 19 which are pivotally connected via hinge means 20 in known manner mutually. Here, the slats 19 are performed when lowering or pulling up the shutter 18 in the guide rail 1.

In bekannter Weise ist das obere Ende des Rollladens 18 bzw. die oberste Lamelle 19 über Federblätter 21 mit der Wickeltrommel 17 verbunden.In known manner, the upper end of the shutter 18 and the uppermost blade 19 is connected via spring leaves 21 to the winding drum 17.

Im hochgezogenen Zustand des Rollladens 18 sind die Lamellen 19 auf der Wickeltrommel 17 aufgerollt. Beim Herunterlassen des Rollladens 18 werden die Lamellen 19 abgewickelt und entlang der Führungsschiene 1 nach unten geführt. Im in Fig. 2 dargestellten Zustand befindet sich der Rollladen 18 in einer fast vollständig heruntergelassenen Position.In the raised state of the shutter 18, the slats 19 are rolled up on the winding drum 17. When lowering the shutter 18, the slats 19 are unwound and guided along the guide rail 1 down. Im in Fig. 2 illustrated state, the shutter 18 is in an almost completely lowered position.

Diese vollständig heruntergelassene Position ist in Fig. 3 dargestellt. Hierbei ist ersichtlich, dass die oberste Lamelle 19 über die Federblätter 21 von der Wickeltrommel 17 weggedrückt wird und praktisch zur Anlage kommt an der Verlängerung 5 der Lasche 4.This fully lowered position is in Fig. 3 shown. It can be seen here that the uppermost lamella 19 is pushed away from the winding drum 17 via the spring blades 21 and practically comes into contact with the extension 5 of the lug 4.

Wenn nun versucht wird, denn Rollladen 18 hochzuschieben, um sich gewaltsam Zugang zu der Gebäudeöffnung verschaffen zu können, bewirken die Federblätter 21, dass die oberste Lamelle 19 des Rollladens 18 der Verlängerung 5 der Lasche 4 folgt, und in das Anschlagelement 7 hineingedrückt wird. Wenn die oberste Lamelle 19 am Anschlagelement 7 anliegt, kann der Rollladen 18 nicht mehr weiter angehoben werden, der Zugang ist gesichert.If an attempt is now made to move shutters 18 up in order to gain access to the building opening by force, the spring leaves 21 cause the uppermost lamella 19 of the roller shutter 18 to follow the extension 5 of the lug 4 and be pressed into the stop element 7. If the uppermost blade 19 abuts the stop element 7, the roller shutter 18 can not be raised further, the access is secured.

Beim normalen Hochziehen des Rollladens aus der vollständig heruntergelassenen Position, wie dies in Fig. 3 dargestellt ist, werden die Federblätter 21 auf der Wickeltrommel 17 aufgewickelt, die oberste Lamelle 19 des Rollladens 18 folgt dann dem Zug dieser Federblätter 21, sie werden somit von der Verlängerung 5 der Lasche 4 weggezogen, dieser Vorgang entspricht der in Fig. 2 dargestellten Situation.During normal pulling up of the shutter from the fully lowered position, as in Fig. 3 is shown, the spring leaves 21 are wound on the winding drum 17, the uppermost blade 19 of the shutter 18 then follows the train of spring leaves 21, they are thus pulled away from the extension 5 of the tab 4, this process corresponds to in Fig. 2 illustrated situation.

Mit dieser Einrichtung wird in einfachster Weise erreicht, dass das gewaltsame Hochschieben des Rollladens 18, um die Gebäudeöffnung gewaltsam freimachen zu können, wirksam verhindert wird.With this device is achieved in the simplest way that the violent pushing up of the shutter 18 in order to free the building opening by force can be effectively prevented.

Zur Erhöhung der Stabilität dieser Einrichtung sind die Gelenkmittel, über welche die obersten drei Lamellen 19 des Rollladens 18 miteinander verbunden sind, mit zusätzlichen Mitteln ausgestattet, welche ein Ausknicken der Lamellen 19 um die Gelenkmittel 20 gegen die Wickeltrommel 17 hin verhindern. Diese zusätzlichen Mittel bestehen im vorliegenden Ausführungsbeispiel aus Stäben 22, die in den Hohlraum der Gelenkmittel 20 der Lamellen 19 eingeschoben sind. Mit diesen Stäben 22 wird erreicht, dass sich die obersten drei Lamellen 19 von der verschwenkten Position, die sie im aufgewickelten Zustand des Rollladens einnehmen, nur bis praktisch in die gestreckte Lage verschwenken können. Auch unter grossem Kraftaufwand zum Hochdrücken des Rollladens wird somit das unerwünschte Ausknicken der obersten, praktisch ungeführten Lamellen 19 wirksam verhindert, der Widerstand gegen das Aufdrücken des Rollladens wird dadurch gross.To increase the stability of this device, the hinge means, via which the top three fins 19 of the shutter 18 connected to each other are equipped with additional means which prevent buckling of the fins 19 about the hinge means 20 against the winding drum 17 out. These additional means consist in the present embodiment of rods 22 which are inserted into the cavity of the hinge means 20 of the fins 19. With these rods 22 it is achieved that the top three lamellae 19 can pivot from the pivoted position, which they occupy in the wound state of the shutter, only until practically in the extended position. Even with great effort to push up the shutter so the unwanted buckling of the top, practically unguided blades 19 is effectively prevented, the resistance to the pressing of the shutter is large.

Selbstverständlich wäre es auch denkbar, dass die Profile, die die Lamellen 19 des Rollladens bilden, im Bereich der Gelenkmittel 20 so ausgebildet sind, dass dadurch ein Ausknicken gegen die Wickeltrommel 17 hin verhindert werden kann.Of course, it would also be conceivable that the profiles that form the slats 19 of the shutter, are formed in the region of the hinge means 20 so that thereby buckling against the winding drum 17 can be prevented out.

Wenn der Rollladen sehr breit ist, wodurch die beiden Lagerträger 3, welche die Wickeltrommel 17 tragen, voneinander einen grossen Abstand haben, kann zur Verbesserung der Stabilität beim Aufdrücken des Rollladens zwischen den beiden Lagerträgern 3 ein zusätzlicher Anschlag 28 vorgesehen sein, der als Haken 27 ausgebildet sein kann, wie dies in Fig. 1 dargestellt ist. Dieser Haken 27 kann in bekannter Weise am oberen Rahmen der Gebäudeöffnung befestigt werden.If the roller shutter is very wide, so that the two bearing carrier 3, which carry the winding drum 17, have a large distance from each other, can be provided to improve the stability when pressing the shutter between the two bearing supports 3, an additional stop 28, the hook as a 27th can be trained, as in Fig. 1 is shown. This hook 27 can be fixed in a known manner to the upper frame of the building opening.

Innerhalb des durch die Abdeckungen 14 und 15 gebildeten Raumes, in welchem der Rollladen mit Lagerung untergebracht ist, kann am Lagerträger 3 im unteren Schlitz 13 eine Lagerung 23 für eine Wickelrolle 24 eines Fliegengitters 29 angebracht werden, wie dies in den Fig. 2 bis 4 ersichtlich ist. Diese Wickelrolle 24 und das Fliegengitter können in bekannter Weise als Rollo ausgebildet sein.Within the space formed by the covers 14 and 15, in which the roller shutter is housed with storage, a bearing 23 for a winding roll 24 of a fly screen 29 can be mounted on the bearing support 3 in the lower slot 13, as shown in the Fig. 2 to 4 is apparent. This winding roll 24 and the fly screen may be formed in a known manner as a roller blind.

Zur Führung des Fliegengitters 29 können entlang der Führungsschienen 1 weitere Führungen 26 angebracht sein, in welchen das Fliegengitter 29 geführt ist.To guide the fly screen 29 further guides 26 may be mounted along the guide rails 1, in which the fly screen 29 is guided.

Die Lagerung 23 der Wickelrolle 24 des Fliegengitters kann hierbei als Kassette ausgebildet sein, die auf die weiteren Führungen 26 aufgesteckt werden können. Um die Kassette im auf die Führungen aufgesteckten Zustand festhalten zu können, ist auf die Kassette eine Abdeckung 25 aufgesetzt, welche mit einem Bolzen im unteren Schlitz 13 des Lagerträgers 3 gehalten ist.The storage 23 of the winding roll 24 of the fly screen can be designed as a cassette, which can be plugged onto the further guides 26. In order to hold the cassette in the mounted on the guides state, a cover 25 is placed on the cassette, which is held with a bolt in the lower slot 13 of the bearing support 3.

Diese Abdeckung 25 ist in vorteilhafter Weise halbzylinderförmig ausgebildet und kann dadurch als Führungshilfe für den Einlauf der Lamellen 19 des Rollladens 18 in die jeweilige Führungsschiene 1 dienen.This cover 25 is advantageously formed semi-cylindrical and can thereby serve as a guide to the inlet of the slats 19 of the shutter 18 in the respective guide rail 1.

Mit diesem Aufbau können Fliegengitter in einfacher Weise und ästhetisch optimal in den Rollladen integriert werden, das Rollo kann auch jederzeit in einfacher Weise ausgewechselt werden, wozu lediglich die Abdeckung 25 weggenommen werden muss.With this structure, fly screens can be integrated in a simple manner and aesthetically optimal in the roller shutter, the roller blind can be replaced at any time in a simple manner, for which only the cover 25 must be removed.
