Description

Die Erfindung bezieht sich auf einen Rolladen für Öffnungsabschlüsse gemäß dem Oberbegriff des Hauptanspruches.The invention relates to a roller shutter for opening closings according to the preamble of the main claim.

Ein Rolladen der bekannten Art wird in der US-A-4345635 beschrieben. Ein solcher Rolladen läßt trotz Sicherung der Gebäudeöffnung Licht eintreten und bei entsprechender Ausbildung der durchsichtigen Kunststoffstäbe können die hinter dem Rolladen, beispielsweise in Schaufenstern ausgelegten Auslagen besichtigt werden. Der bekannte Rolladen hat den Nachteil, daß beim Aufwickeln der Rolladenstäbe auf der Wickelwelle die Kupplungsstäbe mit den Außenseiten der durchsichtigen Rolladenstäbe in Kontakt kommen, so daß hier Kratzer und Verschleißerscheinungen auftreten können, die soweit führen können, daß in diesem Bereich die Rolladenstäbe undurchsichtig sind.A roller shutter of the known type is described in US-A-4345635. Such a roller shutter allows light to enter despite securing the building opening and, with the appropriate design of the transparent plastic rods, the displays behind the roller shutter, for example in shop windows, can be viewed. The known roller shutter has the disadvantage that when the roller shutter rods are wound on the winding shaft, the coupling rods come into contact with the outer sides of the transparent roller shutter rods, so that scratches and signs of wear can occur here, which can lead to the extent that the roller shutter rods are opaque in this area.

Bei dem Vorschlag gemäß der US-PS-4345635 sind an den Enden der plattenförmigen, durchsichtigen Rolladenstäbe Verdickungen angeordnet, von denen nicht näher erläutert wird, wie diese Rippen oder Verdickungen hergestellt werden. Paßgenaue Verdickungen dieser Art herzustellen, ist aber außerordentlich schwierig und kostenaufwendig.In the proposal according to US-PS-4345635 thickenings are arranged at the ends of the plate-shaped, transparent roller shutter bars, of which it is not explained in detail how these ribs or thickenings are produced. Accurate thickening It is extremely difficult and expensive to manufacture this type.

Aus der US-A-1437205 ist ein Rolladen für Türen bekannt, der aus einzelnen, eine unterschiedliche Breite, aber gleiche Länge aufweisenden Rolladenstäben besteht. Die Rolladenstäbe sind dabei an der einen Seite von Gelenkstäben befestigt, die in Anpassung an die unterschiedlichen Breiten der Rolladenstäbe unterschiedliche Länge aufweisen. Beim Aufwickeln wird zwar ein relativ raumsparendes Aufwickeln erreicht, aber die Rückseite der Verbindungsstäbe ruht auf der Sichtseite der darunter angeordneten Rolladenstäbe auf, so daß hier ein Verkratzen und Beschädigen eintreten kann.A roller shutter for doors is known from US-A-1437205, which consists of individual roller shutter bars having a different width but the same length. The roller shutter slats are attached to one side of hinge bars, which have different lengths to match the different widths of the roller shutter slats. When winding a relatively space-saving winding is achieved, but the back of the connecting rods rests on the visible side of the roller shutter rods arranged below, so that scratching and damage can occur here.

Der Erfindung liegt die Aufgabe zugrunde, den gattungsbildenden Rolladen so zu verbessern, daß auch beim Aufrollen des Rolladens auf die Wickelwelle eine Berührung der einzelnen Rolladenstäbe untereinander, mit der Wickelwelle und mit den Kupplungsstäben nicht erfolgt.The invention has for its object to improve the generic roller shutters so that even when rolling up the roller shutter on the winding shaft, the individual roller shutter bars are not in contact with each other, with the winding shaft and with the coupling rods.

Diese der Erfindung zugrundeliegende Aufgabe wird durch die Lehre des Hauptanspruches gelöst.This object on which the invention is based is achieved by the teaching of the main claim.

Vorteilhafte Ausgestaltungen sind in den Unteransprüchen erläutert.Advantageous configurations are explained in the subclaims.

Durch die erfindungsgemäße Anordnung und Ausbildung wird auf jeden Fall ein Verkratzen der Oberflächen der Rolladenstäbe vermieden.The arrangement and design according to the invention in any case prevents the surfaces of the roller shutter bars from being scratched.

Weiterhin wird vorgeschlagen, daß die Rolladenstäbe, die aus einem durchsichtigen Kunststoff, beispielsweise Polykarbonat, bestehen, an ihren oberen und unteren Kanten abgefräst werden, so daß in diesen Endbereichen ein Haken geschaffen wird. Auf diesen Haken wird ein Metallprofil aufgeschoben, das vorzugsweise an seiner Außenseite vollkommen rund ausgebildet ist und dieses runde Metallprofil greift dann in die runde Aufnahmenut des Kupplungsstabes. Diese Anordnung hat sich sowohl in der Herstellung als auch im Betrieb des Rolladens bewährt.It is also proposed that the roller shutter slats, which are made of a transparent plastic, for example Polycarbonate, exist, are milled off at their upper and lower edges, so that a hook is created in these end regions. A metal profile is pushed onto this hook, which is preferably completely round on the outside, and this round metal profile then engages in the round receiving groove of the coupling rod. This arrangement has proven itself both in the manufacture and in the operation of the roller shutter.

Ein Ausführungsbeispiel der Erfindung wird nachfolgend anhand der Zeichnungen erläutert. Die Zeichnungen zeigen dabei in

An embodiment of the invention is explained below with reference to the drawings. The drawings show in
Fig. 1
a section through a winding shaft with wound roller shutter bars, in
Fig. 2
on a larger scale a coupling rod, in
Fig. 3
a roller shutter rod, namely in the drawings a , b , c , d and e the differently wide roller shutter rods, in
Fig. 4
on a larger scale a locking head of a roller shutter rod, in
Fig. 5
a modified version of the roller shutter slats and in
Fig. 6
a locking head on a larger scale.

In den Zeichnungen ist eine Wickelwelle 1 dargestellt, auf die ein Rolladenpanzer aufgerollt ist. Der Rolladenpanzer besteht im wesentlichen aus den einzelnen Rolladenstäben 2 und den Kupplungsstäben 3. Die Größe, d.h. die Breite B der Rolladenstäbe 2 ist unterschiedlich, so daß erreicht wird, daß sich beim Aufrollen des Rolladenpanzers auf der Wickelwelle 1 die Kupplungsstäbe 3 stets aufeinanderlegen und gleichzeitig die einzelnen Rolladenstäbe 2 auch beim Aufrollen auf der Wickelwelle 1 nicht miteinander in Berührung kommen.In the drawings, a winding shaft 1 is shown, on which a roller shutter armor is rolled up. The roller shutter curtain consists essentially of the individual roller shutter bars 2 and the coupling bars 3. The size, that is, the width B of the roller shutter bars 2 is different, so that it is achieved that when the roller shutter curtain rolls up on the winding shaft 1, the coupling bars 3 are always superimposed and simultaneously the individual roller shutter bars 2 do not come into contact with one another even when rolled up on the winding shaft 1.

In Fig. 2 ist in größerem Maßstab ein Kupplungsstab 3 dargestellt. Der Kupplungsstab 3 besteht vorzugsweise aus hochfestem Aluminium und ist gegenüber seiner Längsachse leicht gewölbt ausgebildet. An den beiden Längsrändern 4 und 5 sind Aufnahmenuten 6 und 6a vorgesehen, die rund gestaltet sind und je eine sich nach außen öffnende Öffnung 7 aufweisen. Hierbei wird vorzugsweise so vorgegangen, daß der die Aufnahmenut 6, 6a und die Öffnung 7 begrenzende obere Schenkel 11 etwas länger als der untere Schenkel 10 gewählt ist. Die Öffnung 7 weist weiterhin eine Öffnungsweite a auf, die kleiner ist als die Weite b der eigentlichen Aufnahmenut.In Fig. 2, a coupling rod 3 is shown on a larger scale. The coupling rod 3 is preferably made of high-strength aluminum and is slightly arched with respect to its longitudinal axis. On the two longitudinal edges 4 and 5, receiving grooves 6 and 6a are provided, which are round and each have an opening 7 opening outwards. In this case, the procedure is preferably such that the upper leg 11 delimiting the receiving groove 6, 6a and the opening 7 is somewhat longer than the lower leg 10 is selected. The opening 7 furthermore has an opening width a which is smaller than the width b of the actual receiving groove.

In der Mitte des so gebildeten Kupplungsstabes 3 ist eine zusätzliche Bohrung 9 vorgesehen, die über die gesamte Länge des Kupplungsstabes 3 verläuft und der Aufnahme von Zylinderstababschnitten 16 (Fig. 5) dient. Diese Zylinderstababschnitte 16 weisen eine relativ kleine Länge auf und bewirken somit, daß bei einem Versuch, den Rolladenstab mittels einer Säge durchzutrennen, der Stab 16 sich entsprechend den Sägebewegungen innerhalb der Bohrung 9 drehen kann und somit die Säge unwirksam macht.In the middle of the coupling rod 3 formed in this way, an additional bore 9 is provided which runs over the entire length of the coupling rod 3 and serves to accommodate cylinder rod sections 16 (FIG. 5). These cylinder rod sections 16 have a relatively small length and thus have the effect that when an attempt is made to cut the roller shutter rod by means of a saw, the rod 16 can rotate in accordance with the sawing movements within the bore 9 and thus render the saw ineffective.

In Fig. 3 sind bei a, b, c, d und e verschiedene Rolladenstäbe 2 dargestellt, die sowohl in ihrer Längsachse als auch quer zu ihrer Längsachse aus einer ebenen Polykarbonatplatte bestehen, die vorzugsweise stranggepreßt ist. Beim Herstellen derartiger stranggepreßter Polykarbonatplatten werden Riefen oder ähnliche Beschädigungen der Oberfläche ausgeschaltet. Anschließend wird diese Polykarbonatplatte dann in ihren beiden Endbereichen gerollformt, d.h. es werden die Arretierköpfe 8 und 8a angeformt, die in ihrer Größe den Aufnahmenuten 6 und 6a der Kupplungsstäbe 3 entsprechen. Vorteilhaft ist dabei, daß der Mittelpunkt des Arretierkopfes 8 ― so wie dies die Fig. 4 verdeutlicht ― nicht in der Mittelebene der eigentlichen Platte des Rolladenstabes 2 liegt, sondern versetzt ist, so daß dadurch der erforderliche Abbiegewinkel bei eingesetzten Rolladenstäben 2 in die Aufnahmenuten 6a und 6b erreicht wird, wobei dieser Abbiegewinkel, der wie aus Fig. 1 deutlich ersichtlich vorhanden sein sollte, durch die unterschiedliche Wahl der Länge der Schenkel 10 und 11 unterstützt wird.In Fig. 3 at a , b , c , d and e different shutter bars 2 are shown, which consist both in their longitudinal axis and transversely to their longitudinal axis of a flat polycarbonate plate, which is preferably extruded. When producing such extruded polycarbonate sheets, scoring or similar damage to the surface is eliminated. This polycarbonate plate is then rolled in its two end regions, that is to say the locking heads 8 and 8a are formed, the size of which corresponds to the receiving grooves 6 and 6a of the coupling rods 3. It is advantageous that the center of the locking head 8 - as illustrated in FIG. 4 - does not lie in the central plane of the actual plate of the roller shutter rod 2, but is offset, so that the required bending angle when the roller shutter rods 2 are inserted into the receiving grooves 6a and 6b is reached, this turning angle, which should be present as clearly shown in FIG. 1, is supported by the different choice of the length of the legs 10 and 11.

Aus der voraufgehenden Beschreibung anhand der Zeichnungen wird klar, daß durch den erfindungsgemäßen Vorschlag ein an seiner Außenseite im wesentlichen glattflächiger Rolladen geschaffen wird, der also keine großen Angriffsflächen für Einbrecherwerkzeuge bietet. Während die bisher bekannten, eine Transparenz ermöglichenden Schaufenstergitter mit Haken od. dgl. weggezogen werden können, ist dies bei dem erfindungsgemäßen Rolladen nicht möglich. Der erfindungsgemäße Rolladen kombiniert die gute Durchsichtigkeit weiterhin mit einer Wärmeisolation und dem Schutzeffekt.From the preceding description with reference to the drawings, it is clear that the inventive proposal creates a roller shutter which is substantially smooth on the outside, and which therefore does not offer large areas of attack for burglar tools. While the previously known, transparent window grids with hooks or the like can be pulled away, this is not possible with the roller shutter according to the invention. The roller shutter according to the invention further combines the good transparency with thermal insulation and the protective effect.

In Fig. 5 ist ein Kupplungsstab 3 dargestellt, an den zwei Rolladenstäbe 12 anschließen.5 shows a coupling rod 3 to which two roller shutter rods 12 connect.

In Fig. 6 ist in größerem Maßstab das Endteil eines Rolladenstabes 12 dargestellt, und es ist erkennbar, daß durch Ausfräsen dieses Endbereiches ein Arretierkopf 8b geschaffen wird, der aus einem Hakenteil 15 besteht. Auf diesen Arretierkopf 8b ist ein Metallstab 14 aufgeschoben, dessen Innenausnehmung der Hakenform des Arretierkopfes 8b entspricht und dessen Außenform etwas kleiner als die Aufnahmenuten 6, 6a ist. Hierdurch kann jeder Rolladenstab unter Zwischenschaltung des Metallstabes 14 sicher in den Aufnahmenuten 6 und 6a gehalten werden.In Fig. 6, the end part of a roller shutter rod 12 is shown on a larger scale, and it can be seen that a milling head 8b is created by milling this end portion, which consists of a hook part 15. A metal rod 14 is pushed onto this locking head 8b, the inner recess of which corresponds to the hook shape of the locking head 8b and the outer shape of which is somewhat smaller than the receiving grooves 6, 6a. As a result, each roller shutter slat can be held securely in the receiving grooves 6 and 6a with the interposition of the metal bar 14.

Das Abfräsen der plattenförmigen Rolladenstäbe 12 stellt einen einfachen Arbeitsvorgang dar, wesentlich einfacher als das präzise Formrollen der in Fig. 3 beschriebenen Arretierköpfe.The milling of the plate-shaped roller shutter slats 12 represents a simple operation, much easier than the precise shaping of the locking heads described in FIG. 3.
