Description

Die vorliegende Erfindung betrifft einen Rollladenpanzer mit einer Mehrzahl von parallel angeordneten und miteinander jeweils benachbart gelenkig verbundenen Rollladenstäben, wobei jeder Rollladenstab mit korrespondierenden Haken/Haken-Verbindungen versehen ist, wobei jeder Rollladenstab an seiner einen Längsseite einen Aufnahmehaken und an seiner anderen Längsseite einen Verbindungshaken aufweist und wobei jeder Rollladenstab aus einem einwandigen, dünnen Metallblech besteht.The present invention relates to a roller shutter curtain with a plurality of roller shutter slats arranged in parallel and connected to each other in an articulated manner, each shutter slat being provided with corresponding hook / hook connections, each shutter slat having a receiving hook on its one long side and a connecting hook on its other long side and wherein each roller shutter slat consists of a single-walled, thin sheet of metal.

Rollladen und Rollladenpanzer sind aus der Praxis in vielerlei Ausführungen seit langem bekannt.Roller shutters and roller shutter curtains have long been known from practice in many different designs.

Ein gattungsgemäßer Rollladen mit allen Merkmalen des Oberbegriffs von Anspruch 1 ist aus der DE 947 021 B bekannt. Dort sind die einzelnen mit korrespondierenden Haken/Haken-Verbindungen verbundenen Rollladenstäbe an ihren Rückseiten mittels bandförmiger Überzüge miteinander verbunden.A generic roller shutter with all the features of the preamble of claim 1 is from the DE 947 021 B known. There the individual roller shutter slats connected with corresponding hook / hook connections are connected to one another on their rear sides by means of band-shaped covers.

Die DE 19 83 254 U vermittelt die Lehre, Rollläden, bei denen die Stäbe in der Senkrechten durch Gurte oder Drahtglieder in einem vorgegebenen Abstand zusammengehalten werden, durch eine Rollladen zu ersetzen, bei dem die Stäbe mittels einer biegsamen Folie, jedoch auch zueinander beabstandet, zusammengehalten werden. Hierbei wird das Aufbringen der Folie vorgenommen, wenn der Rollladen voll gestreckt, also mit Zwischenräumen versehen ist. Ein Fachmann kann diesem Dokument keinen Hinweis auf die erfindungsgemäße Lösung entnehmen.The DE 19 83 254 U teaches the teaching of replacing roller shutters, in which the bars are held together vertically by straps or wire links at a predetermined distance, by a roller shutter, in which the bars are held together by means of a flexible film, but also spaced apart. Here, the film is applied when the roller shutter is fully stretched, ie is provided with spaces. A person skilled in the art cannot find any reference to the solution according to the invention from this document.

Ein weiterer Rollladen ist in der DE 31 04 048 A1 beschrieben. Nachteilig an diesem bekannten Rollladen ist die Ausbildung der Rollladenstäbe in Leistenform, da die relativ große Rollladenstabstärke einen relativ großen Ballendurchmesser des aufgewickelten Rollladenpanzers zur Folge hat, was insbesondere beim Nachrüsten von Rollladen oder beim Einsatz für den Passivhausbau von Nachteil ist.Another roller shutter is in the DE 31 04 048 A1 described. The disadvantage of this known roller shutter is the formation of the roller shutter slats in the form of a strip, since the relatively large roller shutter slat thickness results in a relatively large ball diameter of the rolled-up roller shutter curtain, which is particularly disadvantageous when retrofitting roller shutters or when used for passive house construction.

Als weiterer Stand der Technik sind aus der EP 1 048 817 A1 ein "Verfahren zur Herstellung eines Metallfolien-/Gewebeverbundes insbesondere für Rollladenpanzer" und aus der DE 20 2011 000 024 ein "Aufwickelbarer Rollladen" bekannt.Further prior art are from the EP 1 048 817 A1 a "process for the production of a metal foil / fabric composite, especially for roller shutter curtains" and from the DE 20 2011 000 024 a "roll-up roller shutter" known.

Des Weiteren ist ein Rollladenpanzer bekannt, der aus metallischem Bandmaterial gerollformten und zu mit PU-Schaum gefüllten Hohlprofil-Rollladenstäben, die über ausgebildeten Haken und Taschen mit einander verbunden sind, hergestellt sind. Auch hier ergibt sich zwangsläufig eine größere Rollladenstabstärke und somit ein größerer Ballendurchmesser, der wiederum einen größeren Wickelraum benötigt. Ein weiterer Nachteil dieses Systems ist, dass, um eine seitliche Verschiebung der Rollladenstäbe zu verhindern, eine Arretierung der Rollladenstäbe in deren Längsrichtung notwendig ist.Furthermore, a roller shutter curtain is known which is manufactured from metallic strip material which is rolled into hollow profile roller shutter slats which are filled with PU foam and which are connected to one another by means of hooks and pockets. Here, too, there is inevitably a greater thickness of the roller shutter slat and thus a larger bale diameter, which in turn requires a larger winding space. Another disadvantage of this system is that in order to prevent the roller shutter slats from shifting sideways, it is necessary to lock the shutter slats in their longitudinal direction.

Der Erfindung liegt daher die Aufgabe zugrunde, einen Rollladenpanzer der eingangs genannten Art so auszugestalten und weiterzubilden, dass er einen geringeren Ballendurchmesser, eine bessere Wärmedämmung und einen höheren Schallschutz aufweist, sowie kostengünstiger und schneller hergestellt werden kann. Auch soll er ein geringeres Gewicht haben und die Handhabung erleichtern.The invention is therefore based on the object of designing a roller shutter curtain of the type mentioned at the beginning and to further develop that it has a smaller barrel diameter, better thermal insulation and higher soundproofing, and that it can be produced more cheaply and quickly. It should also have a lower weight and facilitate handling.

Gelöst wird diese Aufgabe bei einem Rollladenpanzer mit den Merkmalen des Oberbegriffs von Patentanspruch 1 dadurch, dass jeder Rollladen einen gebogenen Querschnitt aufweist und dass der Verbund aus einwandigen, dünnen die Rollladenstäben einseitig vollflächig und nahezu spielfrei mittels einer durchgehenden Bahn aus einem flexiblen Material verbunden ist.This object is achieved in a roller shutter curtain with the features of the preamble of claim 1 in that each roller shutter has a curved cross-section and that the composite of single-walled, thin roller shutter slats is connected on one side over the entire surface and with almost no play by means of a continuous web made of a flexible material.

Durch die Verwendung eines möglichst dünnen einwandigen Rollladenstabes mit einer Haken/Haken-Verbindung ist es möglich, das Gelenk nahezu spielfrei auszuführen. Weiter kann nur durch die Verbindungsvariante der Drehpunkt möglichst dicht an die Deckschicht gelegt werden, was wiederum vorteilhaft ist, um eine Faltenbildung zu verhindern. Die typische Geräuschentwicklung spielbehafteter Rolladenpanzer wird komplett unterbunden. Bei den heute bekannten Sanierungsmethoden von Gebäuden oder dem Passivhausbau, wo beispielsweise die Wärmedämmung über ein Wärm-Dämm-Verbundsystem erfolgt, ist aufgrund der geringen Masse des Systems und der Notwendigkeit, Fenster und Rollladen in dieser Zone zu montieren, eine schallreduzierte- und platzsparende Lösung möglich. Aufgrund des geringen Ballendurchmessers (kleiner Wickelraum) und des reduzierten Lärmpegels stellt der erfindungsgemäße Rollladenpanzer die optimale Lösung für den Sanierungs- und Passivhausbereich dar.By using the thinnest possible single-walled roller shutter slat with a hook / hook connection, it is possible to design the joint with almost no play. Furthermore, only through the connection variant can the pivot point be placed as close as possible to the cover layer, which in turn is advantageous in order to prevent creasing. The typical noise development of roller shutter curtains with play is completely prevented. With the renovation methods known today for buildings or passive house construction, where, for example, thermal insulation is carried out using a thermal insulation composite system, a sound-reduced and space-saving solution is due to the low mass of the system and the need to install windows and roller shutters in this zone possible. Due to the small ball diameter (small winding space) and the reduced noise level, the roller shutter curtain according to the invention is the optimal solution for the renovation and passive house sector.

Bevorzugt wird der Rollladenpanzer mit der Bahn aus flexiblem Material verklebt.The roller shutter curtain is preferably glued to the sheet made of flexible material.

Gemäß einer weiteren Ausgestaltung der Erfindung sind die Rollladenstäbe aus Aluminium gefertigt. Hier lässt sich durch Rollformung das entsprechend gewünschte Profil der einwandigen dünnen Rollladenstäbe in bekannter Weise herstellen. Diese Ausführung führt zu einem besonders leichten und damit in der Handhabung verbesserten Rollladen.According to a further embodiment of the invention, the roller shutter slats are made of aluminum. Here, the correspondingly desired profile of the single-walled thin roller shutter slats can be produced in a known manner by roll forming. This design leads to a particularly light roller shutter, which is therefore easier to handle.

Eine weitere Lehre der Erfindung sieht vor, dass die Bahn aus flexiblem Material auf der Innenseite des Rollladenpanzers angeordnet ist. Bei dieser Ausgestaltung ist die Bahn aus flexiblem Material bei geschlossenem Rollladen nicht dem Wetter ausgesetzt. Darüber hinaus sorgt sie zum Inneren des Hauses für eine gleichmäßige Fläche und bietet so dem Betrachter eine ruhigere und angenehm anmutende Ansicht.Another teaching of the invention provides that the web made of flexible material is arranged on the inside of the roller shutter curtain. In this embodiment, the sheet of flexible material is not exposed to the weather when the roller shutter is closed. In addition, it ensures a uniform surface towards the interior of the house and thus offers the viewer a calmer and more pleasant view.

In einer weiteren Ausgestaltung der Erfindung kann die Bahn aus flexiblem Material aus unterschiedlichen Materialien bestehen, beispielsweise aus einem textilen Material oder einer Folie aus Kunststoff oder Metall. Hierbei können durch die Wahl des Materials der Bahn die Eigenschaften des Rollladens gesteuert werden.In a further embodiment of the invention, the web made of flexible material can consist of different materials, for example a textile material or a film made of plastic or metal. The properties of the roller shutter can be controlled by choosing the material of the sheet.

Bei dem in der DE 31 04 048 A1 gezeigten Rollladen aus Einzelgliedern mit textiler Deckschicht ist es notwendig, aufgrund der Haken/Taschen-Verbindung des im Ausführungsbeispiel dargestellten Rollladenstabes die Deckschicht in diesem Bereich auszubauchen, um Spiel für das Gelenk zu gewährleisten. Es ist dort zwar auch die Möglichkeit beschrieben, dass durch den Einsatz einer sehr flexiblen Folie auf diese Ausbauchung ("Schlaufe") verzichtet werden kann, dies ist aber nicht wirklich möglich, da die Haken/Taschen-Verbindung für Ihre Funktion stets eine Spaltbildung erfordert.The one in the DE 31 04 048 A1 Shutters made of individual members with a textile cover layer shown, it is necessary, due to the hook / pocket connection of the roller shutter bar shown in the embodiment, to bulge the cover layer in this area to ensure play for the joint. It is there too Describes the possibility that this bulge ("loop") can be dispensed with by using a very flexible film, but this is not really possible because the hook / pocket connection always requires a gap to be formed for its function.

Nachteilig bei einer derartigen Ausführung ist, dass sich diese Ausbuchtungen der Deckschicht im geschlossenen Zustand sich als Falten darstellen, was gerade bei einer beispielsweise mit Motiven bedruckten Deckschicht als störend und unschön empfunden wird. Weiter führen diese Falten beim Aufwickeln des Rollladens zu einer ungewünschten Materialanhäufung, was den Wickeldurchmesser ungünstig und nicht vorhersehbar beeinflusst. Ruht der Rollladen längere Zeit in dieser Position (aufgewickelt), kommt es zu dauerhaft sichtbaren Knickstellen in der Deckschicht (sog. "Bügelfalten"), die auch im geschlossenem Zustand sichtbar sind. Ein weiterer Nachteil dieser Ausführungsform ist die durch das notwendige Taschenspiel der Gelenke bekannte typische Geräuschentwicklung beim Öffnen und Schließen eines solchen Rollladens. Dies ist häufig ein Grund, warum beispielsweise Hotels meist nicht mit Rollläden ausgestattet werden, da das Öffnen und Schließen zu einer erheblichen Lärmbelästigung der Gäste führt.A disadvantage of such an embodiment is that these bulges of the cover layer appear as folds in the closed state, which is perceived as annoying and unattractive in the case of a cover layer printed with motifs, for example. Furthermore, these folds lead to an undesired accumulation of material when the roller shutter is being wound up, which has an unfavorable and unpredictable influence on the winding diameter. If the roller shutter rests in this position (rolled up) for a long time, there are permanently visible kinks in the top layer (so-called "creases"), which are also visible when closed. Another disadvantage of this embodiment is the typical noise development, known from the necessary pocket play of the joints, when opening and closing such a roller shutter. This is often one reason why hotels, for example, are usually not equipped with roller shutters, as opening and closing them leads to considerable noise pollution for guests.

Als nachteilig hat sich weiter gezeigt, dass, wenn die Deckschicht auf der Innenseite angeordnet ist, es in den notwendigen Ausbuchtungen im Bereich der Gelenke zu einer Ansammlung von Abrieb und zum Eintrag von Verschmutzungen durch einen nicht komplett geschlossenen Rollladen kommt. Dies kann zu einer weiteren Lärmpegelerhöhung oder sogar im Extremfall zum Versagen eines Gelenks führen.It has also been shown to be disadvantageous that when the cover layer is arranged on the inside, there is an accumulation of abrasion in the necessary bulges in the area of the joints and the entry of dirt through a roller shutter that is not completely closed. This can lead to a further increase in the noise level or even, in extreme cases, to failure of a joint.

Alle diese Nachteile werden durch den erfindungsgemäßen Rollladenpanzer, insbesondere in seiner Ausführung mit spielfreien Gelenken zuverlässig vermieden.All these disadvantages are reliably avoided by the roller shutter curtain according to the invention, in particular in its design with play-free joints.

Eine weitere Lehre der Erfindung sieht vor, dass die Bahn aus flexiblem Material auch mehrlagig ausgebildet sein kann. Bevorzugt ist dazu auf die Bahn aus flexiblem Material eine wärmeisolierende Schicht aufkaschiert.Another teaching of the invention provides that the web can also be made of flexible material in multiple layers. For this purpose, a heat-insulating layer is preferably laminated onto the web made of flexible material.

Schließlich sieht eine andere Ausgestaltung der Erfindung vor, dass der Rollladenpanzer so ausgestaltet ist, dass er besonders zweckmäßig auf einer runden Wickelwelle aufgerollt werden kann. Auf diese Weise lässt sich der Ballendurchmesser weiter verringern.Finally, another embodiment of the invention provides that the roller shutter curtain is designed in such a way that it can be rolled up on a round winding shaft in a particularly useful manner. In this way, the bale diameter can be further reduced.

The invention is explained in more detail below with the aid of a drawing which merely shows exemplary embodiments. Show in the drawing

Fig. 2
a second embodiment of a roller shutter according to the invention in vertical section and
Fig. 3
the shutter curtain off Fig. 1 in the rolled up state, also in vertical section.

Fig. 1 zeigt einen Teil eines erfindungsgemäßen Rollladenpanzers, bei dem mittig ein Rollladenstab 1 aus einem einwandigen, dünnen Metallblech gezeigt ist, und an den sich nur halb gezeigte Rollladenstäbe 1 nach oben und unten anschließen. Dieser Verbund aus einwandigen dünnen Rollladenstäben 1 ist einseitig mittels einer durchgehenden Bahn 2 aus einem flexiblen Material verbunden, deren Abmessungen denen des gesamten Rollladenpanzers entspricht. Fig. 1 shows a part of a roller shutter curtain according to the invention, in which a roller shutter slat 1 made of a single-walled, thin sheet of metal is shown in the middle, and the shutter slats 1, only half shown, are connected upwards and downwards. This composite of single-walled, thin roller shutter bars 1 is connected on one side by means of a continuous web 2 made of a flexible material, the dimensions of which correspond to those of the entire roller shutter curtain.

Um möglichst spielfreie Gelenke vorzusehen, weisen die Rollladenstäbe 1 an ihrer Unterseite einen Aufnahmehaken 3 und an ihrer Oberseite einen Verbindungshaken 4 auf, die, wie dargestellt, miteinander korrespondieren. Die flexible Bahn 2 überspannt dabei den unweigerlich entstehenden Luftspalt im Bereich beider Haken 3, 4 und sorgt so für einen vollständig geschlossenen Rollladenpanzer. Dadurch, dass der Drehpunkt sehr nah an der flexiblen Bahn 2 liegt, gibt es im Bereich der Gelenke nahezu keine Ausbuchtungen der flexiblen Bahn 2. Durch die spielfreie Verbindung der einzelnen Rollladenstäbe 1 erhöht sich zudem der Schallschutz, da ein "Klappern" etc. durch Windeinfluss bei herabgelassenem Rollladen nicht zu einer Relativbewegung der einzelnen Rollladenstäbe 1 zueinander führen kann. Durch die vollflächige Deckschicht der flexiblen Bahn 2 ergibt sich auch ein verbesserter Schallschutz beim Auf- oder Abwickeln des erfindungsgemäßen Rollladenpanzers.In order to provide joints with as little play as possible, the roller shutter slats 1 have a receiving hook 3 on their underside and a connecting hook 4 on their upper side, which, as shown, correspond to one another. The flexible web 2 spans the inevitably arising air gap in the area of both hooks 3, 4 and thus ensures a completely closed roller shutter curtain. Due to the fact that the pivot point is very close to the flexible sheet 2, there are almost no bulges in the flexible sheet 2 in the area of the joints. The play-free connection of the individual roller shutter slats 1 also increases the soundproofing, since "rattling" etc. The influence of wind when the roller shutter is lowered cannot lead to a relative movement of the individual roller shutter slats 1 to one another. The full-surface cover layer of the flexible web 2 also results in improved soundproofing when the roller shutter curtain according to the invention is wound up or unwound.

In Fig. 2 ist ein weiteres Ausführungsbeispiel eines Rollladenpanzers gezeigt, bei dem auf die flexible Bahn 2 eine wärmeisolierende Schicht (Wärmedämmung) 5 aufgebracht ist und von einer durchgehenden Kaschierung 6 überdeckt ist. Die Darstellung der wärmeisolierenden Schicht 5 ist zum besseren Verständnis überhöht, in der Praxis, gerade beim Passivhausbau, reichen deutlich geringere Stärken von wärmeisolierenden Schichten aus.In Fig. 2 Another exemplary embodiment of a roller shutter curtain is shown in which a heat-insulating layer (thermal insulation) 5 is applied to the flexible web 2 and is covered by a continuous lamination 6. The representation of the heat insulating layer 5 is for Better understanding exaggerated, in practice, especially in passive house construction, significantly lower thicknesses of heat-insulating layers are sufficient.

Schließlich ist in Fig. 3 noch ein aufgewickelter Rollladenpanzer dargestellt. Man erkennt deutlich, dass die erfindungsgemäß äußerst dünnen Rollladenstäbe 1 des dargestellten Rollladenpanzers aufgrund ihrer gebogenen Form und ihrer Stärke aufgewickelt einen sehr geringen Ballendurchmesser haben. Dies lässt sich durch die Verwendung einer kreisrunden Wickelwelle 7 noch verbessern. Versuche der Anmelderin haben ergeben, dass beispielsweise ein erfindungsgemäßer Rollladenpanzer mit einer Länge von 2 m nur einen Ballendurchmesser von 115 mm hat. Zum Vergleich sei ausgeführt, dass bei einer herkömmlichen achteckigen Wickelwelle und einem herkömmlichen Rollladenpanzer mit geschäumten Rollladenstäben bereits ein ein - also nur halb so langer - Meter langer Rollladenpanzer einen größeren Ballendurchmesser hat als die zuvor genannten 115 mm.After all, in Fig. 3 a rolled-up roller shutter curtain is shown. It can be clearly seen that the extremely thin roller shutter slats 1 of the roller shutter curtain shown according to the invention have a very small barrel diameter when wound up due to their curved shape and their thickness. This can be further improved by using a circular winding shaft 7. Tests by the applicant have shown that, for example, a roller shutter curtain according to the invention with a length of 2 m only has a barrel diameter of 115 mm. For comparison, it should be noted that with a conventional octagonal winding shaft and a conventional roller shutter curtain with foamed roller shutter slats, a one meter long roller shutter curtain - i.e. only half as long - has a larger barrel diameter than the 115 mm mentioned above.
