Abstract

Double shell roller shutter for fire-proof doors, consisting of two mutually spaced shells, between which an insulating mat is situated, the two shells being assembled from horizontally arranged slats whose mutually adjacent bent-round edges engage in one another and have a curvature towards the outer sides of the roller shutter, and the axis of rotation of all the slat connections lying in the centre plane of the roller shutter.

Description

Die Erfindung betrifft einen doppelschaligen Rolltorpanzer für Feuerschutztore, welcher aus zwei im Abstand voneinander angeordneten Schalen besteht, zwischen welchen sich eine Dämmatte befindet und wobei die beiden Schalen aus horizontal angeordneten Lamellen zusammengesetzt sind, deren einander benachbarte eingerollte Ränder ineinandergreifen.The invention relates to a double-skin roller shutter curtain for fire doors, which consists of two spaced shells, between which there is an insulating mat and the two shells are composed of horizontally arranged slats, the adjacent rolled edges of which interlock.

Rolltorpanzer der vorgenannten Art sind bereits in unterschiedlichsten Ausführungsformen bekanntgeworden (siehe die DE-A-2349026). Bei diesen befinden sich die beiden Schalen des Panzers in zwei unterschiedlichen, parallel zueinander liegenden Ebenen, wobei, wenn beide Schalen aus Lamellen bestehen, deren gelenkige Verbindungen in der Ebene der jeweiligen Schale liegen.Roller shutter curtains of the aforementioned type have already become known in a wide variety of embodiments (see DE-A-2349026). In these, the two shells of the tank are located in two different planes lying parallel to one another, and if both shells consist of lamellae, their articulated connections lie in the plane of the respective shell.

Weiterhin ist aus der DE-B-16 59 775 ein Rolltorpanzer bekanntgeworden, bei welchem die Lamellen nur der einen, ersten Schale mit ihren eingerollten Rändern gelenkig miteinander verbunden sind, während die einander überlappenden Lamellen der anderen, zweiten Schale jeweils an einer Lamelle der ersten Schale befestigt sind, wobei zwischen den beiden Schalen bzw. deren Lamellen eine Dämmatte angeordnet ist.Furthermore, from DE-B-16 59 775 a roller door curtain has become known, in which the slats of only the first shell are hingedly connected to one another with their rolled-up edges, while the overlapping slats of the other, second shell are each connected to a slat of the first Shell are attached, wherein an insulating mat is arranged between the two shells or their slats.

Rolltorpanzerkonstruktionen der vorbekannten Art sind relativ aufwendig herzustellen und besitzen überdies unerwünschte Wärmebrücken.Roller shutter armor constructions of the known type are relatively complex to manufacture and moreover have undesirable thermal bridges.

Der Erfindung liegt die Aufgabe zugrunde, einen doppelschaligen Rolltorpanzer zu schaffen, der relativ einfach herstellbar und auf eine einzige Wickelrolle aufrollbar ist und bei welchem die beiden Rolltorpanzerschalen vollständig thermisch getrennt sind.The invention has for its object to provide a double-shell roller door curtain that is relatively easy to manufacture and roll up on a single winding roller and in which the two roller door curtain shells are completely thermally separated.

Zur Lösung dieser Aufgabe wird gemäß der Erfindung vorgeschlagen, den Rolltorpanzer für Feuerschutztore in der Weise auszubilden, daß die Lamellen der beiden Panzerschalen eine zur Außenseite des Rolltorpanzers gerichtete Krümmung aufweisen und daß die Drehachsen aller Lamellenverbindungen in der Mittelebene des Rolltorpanzers liegen.To achieve this object, it is proposed according to the invention to design the roller shutter curtain for fire gates in such a way that the slats of the two armored shells have a curvature directed towards the outside of the roller shutter curtain and that the axes of rotation of all slat connections lie in the central plane of the roller shutter curtain.

Vorteilhafterweise sind die Lamellenverbindungen der einen Schale gegenüber den Lamellenverbindungen der anderen Schale in vertikaler Richtung um eine halbe Teilung gegeneinander versetzt angeordnet.Advantageously, the lamellar connections of the one shell are offset by half a division in the vertical direction relative to the lamellar connections of the other shell.

Weitere Merkmale der erfindungsgemäß ausgebildeten Lamellen gehen aus den Unteransprüchen hervor.Further features of the slats designed according to the invention emerge from the subclaims.

In den Figuren 1 bis 4 der Zeichnung ist der Gegenstand der Erfindung anhand bevorzugter Ausführungsbeispiele dargestellt, welche nachstehend im einzelnen näher beschrieben sind. Es zeigen:

Fig. 1
einen Querschnitt durch einen Rolltorpanzer mit den Merkmalen gemäß der Erfindung;
Fig. 2
bis 4 je einen Querschnitt durch eine Lamelle in weiteren Ausführungsformen.
In Figures 1 to 4 of the drawing, the subject matter of the invention is illustrated by means of preferred exemplary embodiments, which are described in more detail below. Show it:
Fig. 1
a cross section through a roller door curtain with the features according to the invention;
Fig. 2
to 4 each have a cross section through a lamella in further embodiments.

Wie aus Fig. 1 hervorgeht, besteht der Rolltorpanzer 11 aus den beiden im Abstand voneinander angeordneten äußeren Schalen 12 und 13, die aus den horizontal angeordneten Lamellen 14 bzw. 15 zusammengesetzt sind. Die Lamellen 14 bzw. 15 greifen in an sich bekannter Weise mit ihren eingerollten Rändern 16 bzw. 17 ineinander, um so die Schalen 12 bzw. 13 zu bilden. Die Lamellen 14 und 15 sind jeweils gegen die Außenseite des Rolltorpanzers 11 gekrümmt, so daß die Drehachsen 18 aller Lamellenverbindungen 16, 17 in der Mittelebene 19 des Rolltorpanzers 11 liegen. Die in Fig. 1 dargestellten Lamellen 14 bzw. 15 haben beispielsweise eine kreisbogenförmige Krümmung.As can be seen from FIG. 1, the roller shutter curtain 11 consists of the two outer shells 12 and 13 which are arranged at a distance from one another and which are composed of the horizontally arranged slats 14 and 15, respectively. The slats 14 and 15 engage in a manner known per se with their rolled-up edges 16 and 17, respectively, so as to form the shells 12 and 13, respectively. The slats 14 and 15 are each curved against the outside of the roller shutter curtain 11, so that the axes of rotation 18 of all the slat connections 16, 17 lie in the central plane 19 of the roller shutter curtain 11. The lamellae 14 and 15 shown in FIG. 1 have, for example, an arcuate curvature.

Die Lamellenverbindungen 16, 17 der einen Schale 12 sind gegenüber denjenigen der anderen Schale 13 um eine halbe Lamellenteilung T/2 versetzt angeordnet. Hierdurch erreicht man bei entsprechender Krümmung der Lamellen 14, 15 einen im wesentlichen gleichmäßig weiten Zwischenraum zwischen den beiden Schalen 12 und 13, der von einer Dämmatte 20 ausgefüllt ist. An den Stellen, wo sich die Lamellenverbindungen 16, 17 befinden, ist der Zwischenraum minimal verengt, so daß dadurch die Dämmatte 20 von den Lamellenverbindungen 16, 17 abgestützt und in ihrer Lage gehalten wird, ohne daß sie sich verschieben kann.The lamellar connections 16, 17 of one shell 12 are offset from those of the other shell 13 by half a lamella pitch T / 2. With a corresponding curvature of the lamellae 14, 15, this results in an essentially uniformly wide space between the two shells 12 and 13, which is filled by an insulating mat 20. At the points where the lamellar connections 16, 17 are located, the space is minimally narrowed, so that the insulating mat 20 is supported by the lamellar connections 16, 17 and held in position without it being able to move.

Da sich die Drehachsen 18 der Lamellenverbindungen 16, 17 sämtlichst in der neutralen Mittelebene 19 befinden, kann der erfindungsgemäß ausgebildete Rolltorpanzer auf eine einzige Wickelrolle aufgerollt werden.Since the axes of rotation 18 of the lamellar connections 16, 17 are all in the neutral central plane 19, the roller shutter curtain designed according to the invention can be rolled up onto a single winding roller.

Die Lamellen 14, 15 können aber auch eine von der Kreisbogenform abweichende Krümmung aufweisen, beispielsweise eine elliptische oder eine parabolische, wie aus den Figuren 2 und 3 hervorgeht, oder sie können eine von einer fest definierten geometrischen Form abweichende Krümmung haben, wie in Fig. 4 dargestellt.The lamellae 14, 15 can also have a curvature that deviates from the circular arc shape, for example one elliptical or parabolic, as can be seen in FIGS. 2 and 3, or they may have a curvature that deviates from a defined geometric shape, as shown in FIG. 4.

Für die Zusammensetzung der Panzerschale finden Lamellen Anwendung, die bis auf die Anfangs- und Endlamellen einander identisch sind. Hieraus ergbit sich insbesondere die kostengünstige Konstruktion des Rolltorpanzers gemäß der Erfindung, der formbedingt auch keine Verbindungselemente zwischen den beiden äußeren Schalen benötigt und der somit frei von Wärmebrücken ist.For the composition of the armored shell, lamellas are used which, apart from the start and end lamellas, are identical to one another. This results in particular in the cost-effective construction of the roller shutter curtain according to the invention, which, due to its shape, does not require any connecting elements between the two outer shells and which is therefore free of thermal bridges.
