Definitions
- the invention relates to a roller shutter according to the preamble of claim 1. More particularly, the invention relates to a roller shutter, the profile bars of which are connected to one another by connecting elements, the connecting elements being able to be completely received in one or two adjacent profile bars.
- Roller shutters essentially consist of profile rods arranged parallel to one another, which together form the roller shutter curtain and, when the roller shutter is closed, must form a flat arrangement that is as gap-free and light-tight as possible.
- the roller shutter must be rollable or foldable, for which the profile rods need sufficient mobility from one another.
- the profile bars are therefore connected to one another by connecting elements.
- roller shutter connections include those that are linked to form chains and are made of bent steel wire (e.g. Regaroll®), as well as two-component connecting elements consisting of sheet steel springs and articulated molded steel wire parts (Regapak®) or sheet steel stampings (Rolpac®). Due to the design, they allow only small bar spacings when the curtain is open, and must be individually inserted into the bars and then linked to form chains.
- Regaroll® bent steel wire
- Rolpac® sheet steel stampings
- An important object of the invention is to create a robust, long-lasting connection of bar profiles that enables them to be linked to hangings in a manner that is easy to assemble.
- the invention is intended to flexibly connect individual profile bars of a roller shutter curtain to one another and thereby guide their movement towards one another in a targeted manner.
- the aim of the movement of the bars during the closing process of the curtain is to keep closing the light gaps between the bars in proportion to the movement so that the bars can be stacked on top of each other in the end position so that they are opaque to form a closed hanging.
- the geometry of the punched rod should be as small as possible in order not to weaken the stability of the rod and to avoid additional light gaps during the closing movement of the curtain.
- the invention should be able to be used equally for folding roller shutters and for wound roller shutters.
- the inventive connection of the profile bars is characterized in that it gives the bars the freedom of movement to change their distance from one another up to the respective end position and serves as a guide element for them during the movement.
- the rods in the first end position of the movement, can be placed on top of one another in an orderly manner and thus a gap-free, opaque arrangement (curtain in closed position).
- an air and light-permeable gap for example approx. 10mm wide, is created.
- a roller shutter 1 with several substantially parallel profile bars 2, 3 and adjacent profile bars 2, 3 connecting connecting elements 4, which allow a relative movement of the profile bars, in which the distance between the adjacent profile bars 2, 3 changes from one another.

- the roller shutter can be a folding roller shutter or a wound roller shutter.
- the roller shutter comprises at least one connecting element 4, which comprises a rod-like connector 5 with two end regions 7, 8, the diameter of which is greater than the diameter of the connector 5 in a central region 9, such as, for. B. in Fig. 1 shown.
- the connector 5 preferably comprises a piece of wire rope (a wire rope section) 6, the diameter and rigidity of which are dimensioned such that it behaves like a flexible rod during operation.
- the piece of wire rope 6 has a limited flexibility, so that it can bend somewhat during operation. However, it must not kink or deform during operation in such a way that it cannot perform its function of guiding the profile bars 2, 3 during their movement undisturbed.
- rod-like connector instead of such a piece of wire rope, for example a rod or a pipe section made of plastic material or metal.
- a stiff hose section can also be considered.
- the wire rope piece 6 is provided at its ends with fixed stops, which can be formed, for example, by pressed-on metal sleeves and form the end regions 7, 8 of the connector 5, in which the diameter of the connector 5 is greater than in its central region 9.
- the diameter of the In this embodiment, the connector in the middle area is the diameter of the piece of wire rope.
- the profile bars 2, 3 connected by the connecting element 4 each have a chamber 10 ( Fig. 4 ), into which the connector 5 extends and in which an end region 7, 8 of the connector 5 is received, such as Fig. 7 shows.
- the chamber 10 is provided with a device 14 which prevents the end region 7, 8 of the connector 5 from leaving the chamber 10.
- the chamber comprises a guide housing 10 ( Fig. 2 ), in which the connector 5 of adjacent profile bars 2, 3 are partially received. If one of these profile bars is an end bar, that is to say has only one other adjacent profile bar, there is only one connector 5 with one of its end regions in the guide housing 10 recorded. In this case, the end area can be fixed in the guide housing 10 in a non-displaceable manner.
- the guide housing 10 When the profile rod 2, 3 is arranged between two respectively adjacent profile rods, the guide housing 10 receives two stops 7, 8 of two connectors 5 movable therein. Within the guide housing 10, the connectors 5, guided in channels, can move up and down.
- the length of the connector 5 is not greater than the sum of the lengths of the two chambers or guide housings 10, which accommodate the end regions 7, 8 of the connector 5, so that the connector can enter the two guide chambers 10 with its entire length so that it is visible between the individual profile bars when the curtain is open and can completely immerse itself in the guide housing during the closing movement of the curtain.
- the guide housing On its sides facing an adjacent profile bar 2, 3, the guide housing is each provided with an opening in the form of a sleeve 14 through which one of the connectors 5 extends and whose clear width is greater than the diameter of the connector 5 in the central area, but less than the diameter of the stop 7.8. The stop can then move in the guide housing 10, but not leave it.
- profile bars 2, 3 are connected by the guide housing 10 anchored therein and the connector 5 to form a chain.
- the guide housings represent the connecting element between the individual wire rope sections.
- the sleeve on the upper side of the housing guides the wire rope during its movement and at the same time forms the upper end stop for the movement within the housing.
- the lengths of the wire rope section and the housing are matched to one another in such a way that the rope sections can dip into the respective housing until the two rods connected by them have come to rest securely on one another.
- Aluminum, zamak or thermoplastic can be used as construction materials.
- the guide housing 10 consists of two halves, preferably geometrically essentially identical, into each of which two wire rope sections are inserted with their end stops. Then the two halves of the housing are plugged into each other and thus form the guide channel for the end stops ( Fig. 3 , 5 , 6th ).
- the number of connecting elements per bar depends on the bar length or the curtain width.
- cavities (chambers) with the exact outer contour of the guide housing are milled in the respective distance depending on the rod length ( Fig. 4 ).
- a second preferred embodiment of the invention shown in Figures 8-10 similar to that, comprises a first embodiment of the invention as shown in FIG Figures 1 to 7 shown, a roller shutter 15 with several substantially parallel to each other arranged profile bars 20, 30 and adjacent profile bars 20, 30 interconnecting connecting elements 40 which allow a relative movement of the profile bars, in which the distance between the adjacent profile bars 20, 30 changes from each other.
- the roller shutter 15 comprises profile rods made of hollow profile material, preferably made of sheet metal.
- the roller shutter can be a folding roller shutter or a wound roller shutter.
- the roller shutter comprises a connecting element 40 with a rod-like connector 50, which comprises a free end region 70, the diameter of which is greater than the diameter of the connector 50 in a central region 90 the other end portion of the connector 50 is attached centrally.
- the guide housing 100 serves to displaceably accommodate the free end region 70 of a connecting element connected to the adjacent profile rod, such as in particular Fig. 10 illustrated.
- the connector 50 preferably comprises a length of wire rope (a wire rope section) 60, the diameter and rigidity of which are dimensioned such that it behaves like a flexible rod in use.
- the piece of wire rope 60 has a limited flexibility so that it can bend somewhat during operation. However, it must not bend or deform during operation in such a way that it cannot perform its function of guiding the profile bars 20, 30 during their movement undisturbed.
- rod-like connector instead of such a piece of wire rope, for example a rod or a pipe section made of plastic material or metal.
- a stiff hose section can also be considered.
- the wire rope piece 60 is provided at one end forming the free end region with a fixed stop 70 in the form of a metal sleeve, through which the diameter of the connector 50 in the free end region is greater than in its central region 90.
- the diameter of the connector in the central region is at In this embodiment, the diameter of the wire rope piece 60.
- the stop 70 comprises a hook area 71 which can be grasped with a tool and which facilitates the introduction of the connector 50 into the guide housing 100 of the adjacent profile bar when the roller shutter is being assembled.
- the guide housing 100 is an approximately U-shaped hollow part, between the legs of which there is an interior space 115 which serves to receive the stop 70 of an adjacent connecting element, as indicated above.
- the guide housing could instead consist of solid material. It can be made of sheet metal, plastic, or any other suitable material.
- the guide housing 100 is provided with devices which prevent the end region 70 of the connector 50 of the adjacent connecting element from leaving the guide housing 100.

These projections delimit an opening 140, the clear width of which is greater than the diameter of the connector 50 in the central region 90, but smaller than the diameter of the stop 70, so that the stop 70 cannot leave the interior space 115.
- the length of the connector 50 is no greater than the length of the interior space 115 that receives the end region (70) of the connector (50) so that the connector can enter the guide housing 100 with its full length so that it can is visible between the individual profile bars when the curtain is open and can completely immerse itself in the guide housing during the closing movement of the curtain.
- profile bars 20, 30 are connected by the guide housing 100 anchored therein and the connector 50 to form a chain, such as Fig. 10 illustrated.
- the guide housing 100 is fastened in the cavity of the profile which forms the profile bar.
- Fig. 10 shows this schematically. It does not necessarily consist of a material that can be directly connected to the profile material.
- the guide housing 100 can therefore be provided with a clip connection.
- This comprises a clip 150 made of a material that can be easily connected to the profile material.
- the clip 150 preferably forms a fastening spring that engages around the lower end of the guide housing and engages in corresponding recesses 155 on the guide housing ( Fig. 8 ).
- the clip can be provided with tabs 151 for its attachment in the hollow profile, Fig. 9 .

- the invention can be used for hollow profiles made of sheet steel, aluminum or composite materials as well as for solid rods made of wood or bamboo composite material.
- At least one profile rod, preferably all profile rods, consists in preferred embodiments of solid material with recesses for the chambers 10.
- the material is preferably at least partially, preferably entirely, selected from wood, bamboo, plastic or metal. Combinations of different materials are possible.
- a suitable bamboo composite material is, for example, the product available under the name MOSO Bamboo X-treme from Moso Italia Srl.
- the invention can be used equally for folding roller shutters and for wound roller shutters. This means that both products can be manufactured on the same production machines. There is no additional incidence of light in the area of the cutouts for connecting hooks.
- the guided closing movement prevents irregular closing of the roller shutter curtain due to possible tilting of the roller shutter slats.
- the invention enables significantly lower noise emissions during the movement of the rods, as well as in the case of vibrations caused by wind.
Abstract
Rollladen, mit mehreren im Wesentlichen parallel zueinander angeordneten Profilstäben und benachbarte Profilstäbe miteinander verbindenden Verbindungselementen, welche eine Relativbewegung der Profilstäbe gestatten, bei welcher sich der Abstand der benachbarten Profilstäbe voneinander verändert.Roller shutters, with several profile bars arranged essentially parallel to one another and connecting elements connecting adjacent profile bars to one another, which allow a relative movement of the profile bars in which the spacing of the adjacent profile bars from one another changes.
Description
Die Erfindung betrifft einen Rollladen gemäß der Präambel von Anspruch 1. Spezieller betrifft die Erfindung einen Rollladen, dessen Profilstäbe durch Verbindungselemente miteinander verbunden sind, wobei die Verbindungselemente in einem oder zwei benachbarten Profilstäben vollständig aufgenommen werden können.The invention relates to a roller shutter according to the preamble of claim 1. More particularly, the invention relates to a roller shutter, the profile bars of which are connected to one another by connecting elements, the connecting elements being able to be completely received in one or two adjacent profile bars.
Rollläden bestehen im Wesentlichen aus parallel zueinander angeordneten Profilstäben, die zusammen den Rollladenpanzer bilden und im geschlossenen Zustand des Rollladens eine möglichst spaltfreie und lichtdichte flächige Anordnung bilden müssen. Andererseits muss der Rollladen rollbar oder faltbar sein, wofür die Profilstäbe eine ausreichende Beweglichkeit voneinander benötigen. Die Profilstäbe sind daher durch Verbindungselemente miteinander verbunden.Roller shutters essentially consist of profile rods arranged parallel to one another, which together form the roller shutter curtain and, when the roller shutter is closed, must form a flat arrangement that is as gap-free and light-tight as possible. On the other hand, the roller shutter must be rollable or foldable, for which the profile rods need sufficient mobility from one another. The profile bars are therefore connected to one another by connecting elements.
Herkömmliche Rollladenverbindungen umfassen solche, die zu Ketten miteinander verknüpft werden und aus gebogenem Stahldraht bestehen (z.B.Regaroll®), sowie zweikomponentige Verbindungselemente bestehend aus Stahlblechfeder und gelenkig verbundenem Stahldrahtformteil (Regapak®) oder Stahblechstanzteil (Rolpac®). Sie ermöglichen konstruktionsbedingt nur geringe Stababstände bei geöffnetem Behang, und müssen einzeln in die Stäbe eingesetzt und anschliessend zu Ketten verknüpft werden.Conventional roller shutter connections include those that are linked to form chains and are made of bent steel wire (e.g. Regaroll®), as well as two-component connecting elements consisting of sheet steel springs and articulated molded steel wire parts (Regapak®) or sheet steel stampings (Rolpac®). Due to the design, they allow only small bar spacings when the curtain is open, and must be individually inserted into the bars and then linked to form chains.
Bei Faltrollläden können die gelenkig miteinander verbundenen Elemente keine zielgerichtete Führungsfunktion während der Bewegung der Stäbe übernehmen. Um die nötige Bewegungsfreiheit der Gelenke zu ermöglichen, müssen grosse Ausstanzungen im Stabprofil vorgenommen werden.In the case of folding roller shutters, the elements that are articulately connected to one another cannot assume a targeted guiding function during the movement of the bars. In order to allow the necessary freedom of movement of the joints, large cutouts must be made in the rod profile.
Eine wichtige Aufgabe der Erfindung besteht darin, eine robuste, langlebige Verbindung von Stabprofilen zu schaffen, die deren montagefreundlichen Verknüpfung zu Behängen ermöglicht.An important object of the invention is to create a robust, long-lasting connection of bar profiles that enables them to be linked to hangings in a manner that is easy to assemble.
Die Erfindung soll einzelne Profilstäbe eines Rollladenpanzers flexibel miteinander verbinden und dabei deren Bewegung zueinander zielgerichtet führen. Ziel der Bewegung der Stäbe während des Schliessvorgangs des Panzers ist es, die Lichtspalte zwischen den Stäben proportional zur Bewegung immer weiter zu schliessen, um die Stäbe in der Endlage lichtundurchlässig zu einem geschlossenen Behang aufeinanderstapeln zu können. Die Geometrie der Stabausstanzung soll dabei möglichst klein sein, um den Stab in seiner Stabilität nicht zu schwächen und zusätzliche Lichtspalte während der Schliessbewegung des Behangs zu vermeiden. Die Erfindung soll gleichermassen für Faltrollladen und für gewickelte Rollladen angewendet werden können.The invention is intended to flexibly connect individual profile bars of a roller shutter curtain to one another and thereby guide their movement towards one another in a targeted manner. The aim of the movement of the bars during the closing process of the curtain is to keep closing the light gaps between the bars in proportion to the movement so that the bars can be stacked on top of each other in the end position so that they are opaque to form a closed hanging. The geometry of the punched rod should be as small as possible in order not to weaken the stability of the rod and to avoid additional light gaps during the closing movement of the curtain. The invention should be able to be used equally for folding roller shutters and for wound roller shutters.
Zur Lösung dieser Aufgabe dient die im Patentanspruch 1 definierte Merkmalskombination. Vorteilhafte Weiterbildungen der Erfindung sind in den abhängigen Patentansprüchen definiert.The combination of features defined in claim 1 is used to solve this problem. Advantageous further developments of the invention are defined in the dependent claims.
Die erfindungsgemäße Verbindung der Profilstäbe zeichnet sich dadurch aus, dass sie den Stäben die Bewegungsfreiheit gibt, ihren Abstand zueinander bis zur jeweiligen Endlage zu verändern und ihnen während der Bewegung als Führungselement dient. Somit wird in der ersten Endlage der Bewegung das geordnete Aufeinanderliegen der Stäbe und damit eine spaltfreie lichtundurchlässige Anordnung möglich (Behang in geschlossener Position). In der anderen Endlage der Bewegung (Behang in geöffneter Position) entsteht ein luft- und lichtdurchlässiger Spalt von beispielsweise ca. 10mm Weite.The inventive connection of the profile bars is characterized in that it gives the bars the freedom of movement to change their distance from one another up to the respective end position and serves as a guide element for them during the movement. In this way, in the first end position of the movement, the rods can be placed on top of one another in an orderly manner and thus a gap-free, opaque arrangement (curtain in closed position). In the other end position of the movement (curtain in the open position), an air and light-permeable gap, for example approx. 10mm wide, is created.

Grundsätzlich umfasst eine bevorzugte erste Ausführungsform der Erfindung, wie in
Der Rollladen kann ein Faltrollladen oder ein gewickelter Rollladen sein.The roller shutter can be a folding roller shutter or a wound roller shutter.
Bei dieser Ausführungsform umfasst der Rollladen wenigstens ein Verbindungselement 4, welches einen stabartigen Verbinder 5 mit zwei Endbereichen 7,8 umfasst, deren Durchmesser größer ist als der Durchmesser des Verbinders 5 in einem Mittelbereich 9, wie z. B. in
Der Verbinder 5 umfasst bevorzugt ein Drahtseilstück (einen Drahtseilabschnitt) 6, dessen Durchmesser und Steifigkeit so bemessen sind, dass es sich im Betrieb wie ein flexibler Stab benimmt. Das Drahtseilstück 6 hat eine gegrenzte Flexibilität, so dass es sich im Betrieb etwas biegen kann. Es darf aber im Betrieb nicht knicken oder sich so verformen, dass es seine Funktion, die Profilstäbe 2,3 bei deren Bewegung zu führen, nicht ungestört wahrnehmen kann.The
Es ist denkbar, statt eines solchen Drahtseilstücks einen anderen stabartigen Verbinder zu verwenden, etwa einen Stab oder einen Rohrabschnitt aus Kunststoffinaterial oder Metall. Auch ein steifer Schlauchabschnitt kommt in Betracht.It is conceivable to use another rod-like connector instead of such a piece of wire rope, for example a rod or a pipe section made of plastic material or metal. A stiff hose section can also be considered.
Das Drahtseilstück 6 ist an seinen Enden mit festen Anschlägen versehen, die zum Beispiel von aufgepressten Metallhülsen gebildet werden können und die Endbereiche 7,8 des Verbinders 5 bilden, in denen der Durchmesser des Verbinders 5 größer ist als in seinem Mittelbereich 9. Der Durchmesser des Verbinders im Mittelbereich ist bei dieser Ausführungsform der Durchmesser des Drahtseilstücks.The
Die durch das Verbindungselement 4 verbundenen Profilstäbe 2,3 weisen jeweils eine Kammer 10 auf (
Die Kammer 10 ist mit einer Vorrichtung 14 versehen, die verhindert, dass der Endbereich 7, 8 des Verbinders 5 die Kammer 10 verlassen kann.The
Die Kammer umfasst bei der hier offenbarten Ausführungsform ein Führungsgehäuse 10 (
Wenn der Profilstab 2,3 zwischen zwei jeweils benachbarten Profilstäben angeordnet ist, nimmt das Führungsgehäuse 10 zwei darin bewegliche Anschläge 7,8 zweier Verbinder 5 auf. Innerhalb der Führungsgehäuse 10 können sich die Verbinder 5, in Kanälen geführt, auf und ab bewegen.When the
Es ist sinnvoll, dass die Länge des Verbinders 5 nicht größer ist als die Summe der Längen der beiden Kammern bzw. Führungsgehäuse 10, die die Endbereiche 7,8 des Verbinders 5 aufnehmen, damit der Verbinder mit ganzer Länge in die beiden Führungskammern 10 eintreten kann, sodass er bei geöffnetem Behang zwischen den einzelnen Profilstäben sichtbar ist und während der Schliessbewegung des Behangs komplett in die Führungsgehäuse eintauchen kann.It makes sense that the length of the
An seinen einem benachbarten Profilstab 2,3 zugewandten Seiten ist das Führungsgehäuse jeweils mit einer Öffnung in Form einer Hülse 14 versehen, durch welche sich einer der Verbinder 5 erstreckt und deren lichte Weite größer ist als der Durchmesser des Verbinders 5 im Mittelbereich , aber geringer als der Durchmesser des Anschlags 7,8. Der Anschlag kann sich dann im Führungsgehäuse 10 bewegen, es aber nicht verlassen.On its sides facing an
Insgesamt werden die Profilstäbe 2,3 durch die darin verankerten Führungsgehäuse 10 und die Verbinder 5 zu einer Kette verbunden.Overall, the profile bars 2, 3 are connected by the
Die Führungsgehäuse stellen das Verbindungselement zwischen den einzelnen Drahtseilabschnitten dar. Die Hülse an der Oberseite des Gehäuses führt das Drahtseil während seiner Bewegung und bildet gleichzeitig den oberen Endanschlag für die Bewegung innerhalb des Gehäuses. Die Längen von Drahtseilabschnitt und Gehäuse sind so aufeinander abgestimmt, dass die Seilabschnitte so weit in die jeweiligen Gehäuse eintauchen können, bis die beiden durch sie verbundenen Stäbe sicher aufeinander zu liegen gekommen sind. Als Konstruktionsmaterial kommen Aluminium, Zamak oder thermoplastischer Kunststoff in Frage.The guide housings represent the connecting element between the individual wire rope sections. The sleeve on the upper side of the housing guides the wire rope during its movement and at the same time forms the upper end stop for the movement within the housing. The lengths of the wire rope section and the housing are matched to one another in such a way that the rope sections can dip into the respective housing until the two rods connected by them have come to rest securely on one another. Aluminum, zamak or thermoplastic can be used as construction materials.
Das Führungsgehäuse 10 besteht bei der hier gezeigten Ausführungsform aus zwei, vorzugsweise geometrisch im Wesentlichen identischen, Hälften, in die jeweils zwei Drahtseilabschnitte mit ihren Endanschlägen eingelegt werden. Anschliessend werden die beiden Gehäusehälften ineinandergesteckt und bilden so den Führungskanal für die Endanschläge (
Um zwei Stäbe eines Rollladenpanzers miteinander zu verbinden werden die zusammengesteckten Verbindungselemente anschliessend in die jeweiligen Rollladenstäbe eingepresst.In order to connect two bars of a roller shutter curtain to one another, the plugged-together connecting elements are then pressed into the respective roller shutter bars.
Die Anzahl der Verbindungselemente pro Stab richtet sich nach der Stablänge bzw. der Behangbreite.The number of connecting elements per bar depends on the bar length or the curtain width.
Es sind mindestens zwei Verbindungselemente pro Stab vorgesehen.There are at least two connecting elements per rod.
In Stäbe aus Vollmaterial (Holz, Bambus-Verbundmaterial etc.) werden zunächst Hohlräume (Kammern) mit der exakten Aussenkontur der Führungsgehäuse im jeweiligen, von der Stablänge abhängigen Abstand, eingefräst (
Beginnend mit dem untersten Stab des Behangs, dem sogenannten Schlussstab, werden alle Rollladenstäbe durch die zusammengesteckten Verbindungselemente miteinander verbunden. Aussschliesslich beim Schlussstab wird nur jeweils der Endanschlag eines einzigen Drahtseilabschnitts in die jeweiligen Führungsgehäuse eingelegt und anschliessend mit dem Stab verpresst.Starting with the lowest bar of the curtain, the so-called final bar, all roller shutter bars are connected to one another by the plugged-together connecting elements. Exclusively in the case of the end rod, only the end stop of a single wire rope section is inserted into the respective guide housing and then pressed with the rod.
Die Montagefolge für den Schlussstab:
- a) in jede Ausfräsung des Schlussstabs wird von oben durch eine oben in
Fig. 4 gezeigte kreisförmige Öffnung (welche die Hülse des Führungsgehäuses aufnimmt) ein Montagewerkzeug durch den Stab geschoben; - b) jeweils ein Endanschlag eines Stahlseilabschnitts wird mit einem Montagewerkzeug verbunden;
- c) der jeweils andere Endanschlag des Stahlseilabschnitts wird in eine der beiden Führungsgehäusehälften eingelegt.
- d) Die beiden Gehäusehälften werden zusammengesteckt.
- e) Anschliessend wird gleichzeitig der jeweils obere Endanschlag eines Stahlseilabschnitts mittels Montagewerkzeug nach oben gezogen und das jeweilige Führungsgehäuse in die jeweilige Ausfräsung im Stab gepresst.
- a) in each cutout of the end rod is inserted from above through a top in
Fig. 4 circular opening shown (which receives the sleeve of the guide housing) pushed an assembly tool through the rod; - b) in each case one end stop of a steel cable section is connected to an assembly tool;
- c) the other end stop of the steel cable section is inserted into one of the two guide housing halves.
- d) The two halves of the housing are plugged together.
- e) Then, at the same time, the respective upper end stop of a steel cable section is pulled up using an assembly tool and the respective guide housing is pressed into the respective cutout in the rod.
Bei allen anderen Stäben wird jeweils ein Endanschlag von zwei Drahtseilabschnitten in die jeweiligen Führungsgehäuse eingelegt und diese werden anschliessend mit dem Stab verpresst.For all other rods, an end stop of two wire rope sections is inserted into the respective guide housing and these are then pressed with the rod.
Die Montagefolge für den Behang (ausser Schlussstab):
- a) in jede Ausfräsung des zu montierenden Stabes wird von oben durch die kreisförmige Öffnung ein Montagewerkzeug durch den Stab geschoben;
- b) jeweils ein Endanschlag eines Stahlseilabschnitts wird mit einem Montagewerkzeug verbunden;
- c) der jeweils andere Endanschlag des Stahlseilabschnitts wird in eine der beiden Führungsgehäusehälften eingelegt.
- d) Der obere Endanschlag des jeweiligen Stahlseilabschnitts des vorherigen Stabes wird ebenfalls in diese Führungsgehäusehälften eingelegt.
- a) an assembly tool is pushed through the rod from above through the circular opening into each cutout of the rod to be assembled;
- b) in each case one end stop of a steel cable section is connected to an assembly tool;
- c) the other end stop of the steel cable section is inserted into one of the two guide housing halves.
- d) The upper end stop of the respective steel cable section of the previous rod is also inserted into these guide housing halves.
Mit dieser Montagefolge werden alle zu einem kompletten Behang verknüpft.
Es sind jeweils zwei Stahlseilabschnitte durch jeweils einen ihre Endanschläge in einem Führungsgehäuse so zusammen eingeschlossen, dass sie sich die Endanschläge innerhalb des Gehäuses frei auf und ab bewegen können.With this assembly sequence, all are linked to form a complete curtain.
Two steel cable sections are each enclosed by one of their end stops in a guide housing so that they can move the end stops freely up and down within the housing.
Im Gebrauchszustand "Behang geöffnet" entstehen so grosse Lichtschlitze zwischen den Stäben, weil sich die Stahlseilabschnitte komplett zwischen den jeweiligen Stäben befinden und nur ihre jeweiligen Endanschläge innerhalb der Führungsgehäuse gehalten werden. Im Gebrauchszustand "Behang geschlossen" hingegen sind die Stahlseilabschnitte komplett in die jeweiligen Führungsgehäuse eingeschoben, sodass die Stäbe direkt aufeinanderliegen und sämtliche Lichtschlitze verschlossen sind.In the state of use "curtain open", large slits of light are created between the rods because the steel cable sections are completely located between the respective rods and only their respective end stops are held within the guide housing. In the "curtain closed" state of use, however, the steel cable sections are completely pushed into the respective guide housing so that the rods lie directly on top of one another and all light slots are closed.
Eine zweite bevorzugte Ausführungsform der Erfindung, die in
Der Rollladen kann ein Faltrollladen oder ein gewickelter Rollladen sein.
Bei dieser Ausführungsform umfasst der Rollladen ein Verbindungselement 40 mit einem stabartigen Verbinder 50, der einen freien Endbereich 70 umfasst, dessen Durchmesser größer ist als der Durchmesser des Verbinders 50 in einem Mittelbereich 90. Das Verbindungselement 40 umfasst weiterhin ein Führungsgehäuse 100, an dessen Oberseite 75 der andere Endbereich des Verbinders 50 mittig befestigt ist. Das Führungsgehäuse 100 dient zur verschieblichen Aufnahme des freien Endbereichs 70 eines mit dem benachbarten Profilstab verbundenen Verbindungselements, wie insbesondere
In this embodiment, the roller shutter comprises a connecting
Es ist denkbar, statt eines solchen Drahtseilstücks einen anderen stabartigen Verbinder zu verwenden, etwa einen Stab oder einen Rohrabschnitt aus Kunststoffinaterial oder Metall. Auch ein steifer Schlauchabschnitt kommt in Betracht.It is conceivable to use another rod-like connector instead of such a piece of wire rope, for example a rod or a pipe section made of plastic material or metal. A stiff hose section can also be considered.
Das Drahtseilstück 60 ist an einem, den freien Endbereich bildenden, Ende mit einem festen Anschlag 70 in Form einer Metallhülse versehen, durch die der Durchmesser des Verbinders 50 im freien Endbereich größer ist als in seinem Mittelbereich 90. Der Durchmesser des Verbinders im Mittelbereich ist bei dieser Ausführungsform der Durchmesser des Drahtseilstücks 60. Der Anschlag 70 umfasst einen Hakenbereich 71, der mit einem Werkzeug erfasst werden kann und beim Zusammenbau des Rollladens die Einführung der Verbinder 50 in das Führungsgehäuse 100 des benachbarten Profilstabs erleichtert.The
Das Führungsgehäuse 100 ist bei dieser Ausführungsform ein etwa U-förmiges Hohlteil, zwischen dessen Schenkeln ein Innenraum 115 liegt, der zur Aufnahme des Anschlags 70 eines benachbarten Verbindungselements dient, wie oben angegeben. Das Führungsgehäuse könnte stattdessen aus Vollmaterial bestehen. Es kann aus Blech, Kunststoff oder jedem anderen geeigneten Material hergestellt werden.In this embodiment, the
Das Führungsgehäuse 100 ist mit Vorrichtungen versehen, die verhindern, dass der Endbereich 70 des Verbinders 50 des benachbarten Verbindungselements das Führungsgehäuse 100 verlassen kann. Diese Vorrichtungen umfassen einwärts gerichtete Vorsprünge 141, 142, die innenseitig am Ende der Schenkel des Führungsgehäuses ausgebildet sind (
Wenn einer dieser Profilstäbe ein Endstab ist, also nur einen benachbarten anderen Profilstab hat, ist nur ein Verbinder 50 mit seinem freien Endbereich im Führungsgehäuse 100 des benachbarten Profilstabs aufgenommen. Das Führungsgehäuse des Endstabs dient dann nur zu seiner Befestigung am Endstab.If one of these profile bars is an end bar, that is to say has only one other adjacent profile bar, only one
Es ist sinnvoll, dass die Länge des Verbinders 50 nicht größer ist als die als die Länge des Innenraums 115, der den Endbereich (70) des Verbinders (50) aufnimmt, damit der Verbinder mit ganzer Länge in das Führungsgehäuse 100 eintreten kann, sodass er bei geöffnetem Behang zwischen den einzelnen Profilstäben sichtbar ist und während der Schliessbewegung des Behangs komplett in das Führungsgehäuse eintauchen kann.It makes sense that the length of the
Insgesamt werden die Profilstäbe 20, 30 durch die darin verankerten Führungsgehäuse 100 und die Verbinder 50 zu einer Kette verbunden, wie
Das Führungsgehäuse 100 wird in dem Hohlraum des Profils befestigt, welches den Profilstab bildet.
Der Profilstab 20, 30 kann mit Versteifungsrillen 21, 22 versehen sein, wie in
Ein erfindungsgemäßer Rollladen umfasst eine Mehrzahl von Profilstäben, die aus gleichem oder verschiedenem Material bestehen können. Durch Anpassung des Führungsgehäuses ist die Erfindung sowohl für Hohlprofile aus Stahlblech, Aluminium oder Composit- Materialien als auch für Vollstäbe aus Holz oder Bambus-Verbundmaterial einsetzbar. Wenigstens ein Profilstab, vorzugsweise alle Profilstäbe, besteht in bevorzugten Ausführungsformen aus Vollmaterial mit Ausnehmungen für die Kammern 10. Das Material ist vorzugsweise wenigstens teilweise, vorzugsweise ganz, aus Holz, Bambus, Kunststoff oder Metall ausgewählt. Kombinationen verschiedener Materialien sind möglich.A roller shutter according to the invention comprises a plurality of profile rods which can consist of the same or different material. By adapting the guide housing, the invention can be used for hollow profiles made of sheet steel, aluminum or composite materials as well as for solid rods made of wood or bamboo composite material. At least one profile rod, preferably all profile rods, consists in preferred embodiments of solid material with recesses for the
Als Bambus-Verbundmaterial eignet sich beispielsweise das unter der Bezeichnung MOSO Bamboo X-treme von Moso Italia Srl erhältliche Produkt.A suitable bamboo composite material is, for example, the product available under the name MOSO Bamboo X-treme from Moso Italia Srl.
Die Erfindung kann gleichermassen für Faltrollladen und für gewickelte Rollladen angewendet werden. Dadurch können beide Produkte auf den gleichen Produktionsmaschinen hergestellt werden. Es ergibt sich kein zusätzlicher Lichteinfall im Bereich der Ausstanzungen für Verbindungshaken. Durch die geführte Schliessbewegung wird ein unregelmässiges Schliessen des Rollladenpanzers durch eventuelles Verkanten der Rollladenstäbe verhindert. Die Erfindung ermöglicht deutlich geringere Geräuschemmission während der Bewegung der Stäbe, als auch bei von Wind verursachten Vibrationen.The invention can be used equally for folding roller shutters and for wound roller shutters. This means that both products can be manufactured on the same production machines. There is no additional incidence of light in the area of the cutouts for connecting hooks. The guided closing movement prevents irregular closing of the roller shutter curtain due to possible tilting of the roller shutter slats. The invention enables significantly lower noise emissions during the movement of the rods, as well as in the case of vibrations caused by wind.
