Description
Die vorliegende Erfindung betrifft einen Deckengeienkrolladen gemäß dem Oberbegriff des Anspruches 1.The present invention relates to a ceiling roller shutter according to the preamble of claim 1.
Ein solcher Deckengeienkrolladen ist beispielsweise aus dem deutschen Gebrauchsmuster 296 01 055 bekannt.Such a ceiling roller shutter is known, for example, from the German utility model 296 01 055.
Dieser Deckengelenkroliaden, der sich im täglichen Betrieb sehr bewährt hat, weist ebenso wie andere eine Zugfeder auf, durch die eine Absturzsicherung für den Fall gebildet wird, daß beispielsweise ein angeschlossener Motor nicht funktionsfähig ist.This ceiling-mounted roller shutter, which has proven itself in daily use, has, like others, a tension spring that provides fall protection in the event that, for example, a connected motor is not functioning.
Diese Zugfeder ist etwa im Mittenbereich angeordnet und dort an einem Federkanal aufgehängt, der wiederum an einem Motor, durch den der Rolladen bewegbar ist, befestigt ist.This tension spring is located approximately in the middle area and is suspended from a spring channel, which in turn is attached to a motor that moves the roller shutter.
Dieser Federkanal besteht üblicherweise aus einer C-förmigen Schiene und muß zusammen mit dem Motor vormontiert werden.This spring channel usually consists of a C-shaped rail and must be pre-assembled together with the motor.
Naturgemäß ist dies nicht nur mit einem erheblichen Vormontageaufwand verbunden, einschließlich der notwendigen Bereitstellung der separaten C-Schiene, sondern auch mit einem erhöhten Aufwand bei der Endmontage. Überdies ist ein Auswech-Naturally, this not only involves considerable pre-assembly work, including the necessary provision of the separate C-rail, but also involves increased work during final assembly. In addition, replacing

sein des Motors, beispielsweise bei dessen Ersatz, nur insoweit möglich, als dieser neue Motor die gleichen Anbaumaße aufweisen muß. Eine freie Auswahl des Motors, die auch bei einer Neumontage wünschenswert wäre, ist nicht möglich.The motor can only be used, for example when replacing it, if the new motor has the same mounting dimensions. A free choice of motor, which would also be desirable for a new installation, is not possible.
Der vorliegenden Erfindung liegt daher die Aufgabe zugrunde, einen Deckengelenkrolladen der gattungsgemäßen Art so zu gestalten, daß kein separater Führungskanal für die Zugfeder erforderlich ist und daß für einen Motorbetrieb unterschiedliche Motoren eingesetzt werden können.The present invention is therefore based on the object of designing a ceiling-mounted roller shutter of the generic type in such a way that no separate guide channel is required for the tension spring and that different motors can be used for motor operation.
Diese Aufgabe wird durch einen Deckengeienkroiladen gelöst, der die Merkmale des Anspruches 1 aufweist.This object is achieved by a ceiling-mounted croquette having the features of claim 1.
Durch diese konstruktive Ausgestaltung des Deckengelenkrolladens kann auf den Einsatz eines separaten Federkanals, der an dem Motor angeschlossen ist, verzichtet werden. Eine Vormontage, wie bislang erforderlich, entfällt.This structural design of the ceiling roller shutter means that the use of a separate spring channel connected to the motor is no longer necessary. Pre-assembly, as was previously necessary, is no longer necessary.
Außerdem kann nunmehr jeder beliebige geeignete Motor eingesetzt werden.In addition, any suitable motor can now be used.
Nach einer vorteilhaften Ausgestaltung der Erfindung ist vorgesehen, daß die Zugfedern jeweils in einem Federkanal angeordnet sind, der Bestandteil der zugeordneten horizontalen Führungsschiene ist.According to an advantageous embodiment of the invention, it is provided that the tension springs are each arranged in a spring channel which is part of the associated horizontal guide rail.
Dabei kann die Zugfeder entweder an diesem Federkanai oder am Baukörper befestigt sein.The tension spring can be attached either to this spring channel or to the structure.
Nach einem weiteren Gedanken der Erfindung ist vorgesehen, daß jede Zugfeder in an sich bekannter Weise mit einem Flaschenzug verbunden ist, über den ein Seilzug geführt ist, der an der in Schließstellung des Deckengelenkrolladens untersten Lamelle befestigt ist. Hierdurch werden die Lamellengelenke entlastet.According to a further idea of the invention, it is provided that each tension spring is connected in a known manner to a pulley, over which a cable is guided, which is attached to the lowest slat in the closed position of the ceiling-mounted roller shutter. This relieves the load on the slat joints.
Weitere vorteilhafte Ausgestaltungen der Erfindung sind in den Unteransprüchen gekennzeichnet.Further advantageous embodiments of the invention are characterized in the subclaims.
Ein Ausführungsbeispiel der Erfindung wird nachfolgend anhand der beigefügten Zeichnungen beschrieben.An embodiment of the invention is described below with reference to the accompanying drawings.

Figur 4 eine Einzelheit des Deckengelenkroliadens in einer Seitenansicht,
Figur 5 die Einzelheit in einer Draufsicht.Figure 4 a detail of the ceiling joint roller blind in a side view,
Figure 5 shows the detail in a plan view.
In den Fig. 1 und 2 ist ein Deckengelenkrolladen dargestellt, der aus einer Vielzahl gelenkig miteinander verbundenen Lamellen 1 besteht, die in Führungsschienen 2,3 geführt sind, von denen eine 2 vertikal und die andere 3 horizontal verläuft.Figures 1 and 2 show a ceiling-mounted roller shutter, which consists of a plurality of slats 1 connected to one another in an articulated manner and guided in guide rails 2, 3, one of which 2 runs vertically and the other 3 runs horizontally.
Im gemeinsamen Endbereich der Führungsschienen 2,3 ist eine Stützrolle 4 angeordnet, auf der die Lamellen beim Öffnen und Schließen des Deckengelenkroliadens aufliegen.A support roller 4 is arranged in the common end area of the guide rails 2,3, on which the slats rest when the ceiling hinge roller blind is opened and closed.
Wie die Fig. 3 besonders deutlich zeigt, besteht die horizontale Führungsschiene 3 aus einer Laufschiene 5, in der - wie erwähnt - die Lamellen 1 geführt sind, einem davon angeordneten Federkanal 6 sowie einer seitlich dazu angeordneten Kammer 15.As Fig. 3 shows particularly clearly, the horizontal guide rail 3 consists of a guide rail 5 in which - as mentioned - the slats 1 are guided, a spring channel 6 arranged therefrom and a chamber 15 arranged to the side thereof.
In dem Federkanal 6 ist eine Zugfeder 7 angeordnet, die im vorliegenden Ausführungsbeispiel mit einem Ende in eine Öse 14 eingehängt ist, die mit einer den Federkanal 6 verschließenden Endkappe 13 verbunden ist.A tension spring 7 is arranged in the spring channel 6, which in the present embodiment is hooked with one end into an eyelet 14, which is connected to an end cap 13 closing the spring channel 6.
An das andere Ende der Zugfeder 7 ist eine Rolle 8 angehängt, die Bestandteil eines Flaschenzuges ist, der eine weitere Rolle 9 aufweist, die im Gegensatz zur Rolle 8 feststeht und über die ebenso wie über die Rolle 8 ein Seilzug 10 geführt ist, der einerseits an der Rolle 9 und andererseits an der in Schließstellung des Deckengelenkrolladens untersten Lamelle 1 befestigt ist.A roller 8 is attached to the other end of the tension spring 7, which is part of a pulley that has another roller 9, which, in contrast to the roller 8, is fixed and over which, like over the roller 8, a cable 10 is guided, which is fastened on the one hand to the roller 9 and on the other hand to the lowest slat 1 in the closed position of the ceiling-mounted roller shutter.
Dabei ist dieser Seilzug in einer Rille 12 der Stützrolle 4 geführt.This cable is guided in a groove 12 of the support roller 4.
Die Rolle 8 ist dabei ebenso wie die Zugfeder 7 im Federkanal 6 plaziert und kann sich in Längsachsrichtung des Federkanals 6 frei hin und her bewegen.The roller 8, like the tension spring 7, is placed in the spring channel 6 and can move freely back and forth in the longitudinal axis direction of the spring channel 6.
Die Rolle 9 ist drehbar an einem Tragteil 11 befestigt, das in die Kammer 15 eingesteckt und dort, beispielsweise mittels Schrauben, festgesetzt ist. Hierdurch wird eine sehr einfache und leichte Montage ermöglicht. Um einen fluchtenden Verlauf des Seilzuges 10 zu erreichen, ist die Rolle 9 über ein Distanzstück 16 mit dem Tragteil 11 verbunden.The roller 9 is rotatably attached to a support part 11, which is inserted into the chamber 15 and secured there, for example by means of screws. This enables very simple and easy assembly. In order to achieve an aligned course of the cable 10, the roller 9 is connected to the support part 11 via a spacer 16.
