Description

Die Erfindung betrifft eine Rolloeinrichtung zum Einbau in den Scheibenzwischenraum einer Isolierglasscheibe sowie eine Isolierglasscheibe mit integrierter Rolloeinrichtung, die in den hermetisch abgedichteten Zwischenraum zwischen den beiden Einzelglasscheiben der Isolierglasscheibe eingebaut ist.The invention relates to a roller blind device for installation in the space between the panes of an insulating glass pane and an insulating glass pane with an integrated roller blind device which is installed in the hermetically sealed space between the two individual glass panes of the insulating glass pane.

Aus der EP 0 483 528 A1 ist eine Isolierglasscheibe mit einer im Scheibenzwischenraum eingebauten Rolloeinrichtung mit den Merkmalen der Oberbegriffe der unabhängigen Ansprüche 1 und 5 bekannt. Bei dieser bekannten Rolloeinrichtung dient ein Elektromotor dazu, das auf einem Wickelkörper aufgerollte Rollo über einen Zugstab in der gewünschten Weise in Schließstellung zu bewegen. Auf den Wickelkörper wirkt ein das Rollo in seine Aufwickelstellung vorspannende Gegenzugeinrichtung in Gestalt einer im Wickelkörper eingebauten Torsionsfeder, oder es findet ein zweiter Elektromotor als Gegenzugeinrichtung Anwendung.EP 0 483 528 A1 discloses an insulating glass pane with a roller blind device installed in the space between the panes with the features of the preambles of independent claims 1 and 5. In this known roller blind device, an electric motor serves to move the roller blind, which is rolled up on a winding former, into the closed position in the desired manner via a pull rod. A counter-pulling device, which prestresses the roller blind into its winding position, acts on the winding body in the form of a torsion spring installed in the winding body, or a second electric motor is used as a counter-pulling device.

Bei dieser bekannten Anordnung sind entweder zwei getrennte Elektromotoren für den Antrieb des Rollos in der Öffnungs- oder Schließrichtung notwendig, die dann beide jeweils in der einen oder anderen Drehrichtung betrieben werden müssen, oder es ist eine Torsionsfeder als Gegenzugeinrichtung notwendig. Im ersteren Fall ist die Konstruktion aufwendig, im letzteren Fall steht das Rollo wegen der Gegenzug-Torsionsfeder ständig unter Spannung, die mit zunehmendem Abwickeln des Rollos steigt, wodurch die Gefahr gegeben ist, daß Teile brechen oder reißen können, und was auch bedingt, daß der Elektromotor für den Antrieb so groß dimensioniert sein muß, daß er außer der notwendigen Antriebskraft zum Bewegen des Rollos auch noch die Gegenzugkraft überwinden kann.In this known arrangement, either two separate electric motors are required to drive the blind in the opening or closing direction, both of which must then each be operated in one or the other direction of rotation, or a torsion spring is required as a counter-pulling device. In the former case, the construction is complex, in the latter case the roller blind is constantly under tension due to the counter-tension torsion spring, which increases as the roller blind unwinds, which means that there is a risk of parts breaking or tearing can, and what also requires that the electric motor for the drive must be dimensioned so large that in addition to the necessary driving force for moving the roller blind, it can also overcome the counter-pulling force.

Aufgabe der Erfindung ist es daher, eine Rolloeinrichtung zu schaffen, die ohne Gegenzugfeder mit nur einem Elektromotor zum Bewegen des Rollos in öffnungs- oder Schließbewegung auskommt.The object of the invention is therefore to provide a roller blind device which does not need a counter-tension spring with only one electric motor for moving the roller blind in the opening or closing movement.

Diese Aufgabe wird gemäß der Erfindung durch eine Rolloeinrichtung gelöst, wie sie in den unabhängigen Patentansprüchen 1 und 5 in Gestalt zweier äquivalenter Lösungsmöglichkeiten angegeben ist. Beide Lösungsmöglichkeiten erzeugen eine jeweils synchrone Bewegung des auf den Zugstab des Rollos wirkenden Zugorgans mit der den Wickelkörper mit dem Rollo tragenden drehbaren Achse bei Betätigung des elektromotorischen Antriebs in der einen oder anderen Richtung zum Schließen bzw. Öffnen des Rollos.This object is achieved according to the invention by a roller blind device, as specified in independent patent claims 1 and 5 in the form of two equivalent solutions. Both possible solutions produce a synchronous movement of the pulling element acting on the pull rod of the roller blind with the rotatable axis carrying the winding body with the roller blind when the electromotive drive is actuated in one or the other direction to close or open the roller blind.

Das Merkmal des Anspruchs 8 ist für sich aus dem deutschen Gebrauchsmuster DE 93 01 141 U1 bekannt, das eine Straffungseinrichtung für Behänge von ein- und ausfahrbaren Beschattungsanlagen und Markisen betrifft.The feature of claim 8 is known per se from German utility model DE 93 01 141 U1, which relates to a tightening device for curtains of retractable and extendable shading systems and awnings.

Zwei Ausführungsbeispiele der Erfindung entsprechend den beiden alternativen Aufgabenlösungen nach den Patentansprüchen 1 und 5 werden nachstehend unter Bezugnahme auf die anliegenden Zeichnungen mehr im einzelnen beschrieben. In den Zeichnungen zeigt:

a representation similar to FIG. 1 of a second embodiment of an insulating glass pane with integrated roller blind device.

Die in den Zeichnungen dargestellten Anordnungen bestehen jeweils aus zwei Einzelglasscheiben 1, 2, die in dem heute üblichen Abstand von 16 mm angeordnet sein können und zwischen sich die nachstehend beschriebene Rolloeinrichtung aufnehmen. Das ganze System ist unter Einbau eines Aluminiumstegs 3 diffusionsdicht abgeschlossen, farbrikmäßig herstellbar, wartungsfrei und läßt sich problemlos in bekannte Fensterrahmen einbauen. Die zwischen den beiden Glasscheiben 1, 2 angeordnete Rolloeinrichtung kann wahlweise als Sonnenschutz oder zur Vollverdunkelung ausgebildet sein.The arrangements shown in the drawings each consist of two individual glass panes 1, 2, which can be arranged at the usual spacing of 16 mm and between them accommodate the roller blind device described below. The entire system is sealed diffusion-tight with the installation of an aluminum web 3, can be produced in terms of color, is maintenance-free and can be easily fitted into known window frames Install. The roller blind device arranged between the two glass panes 1, 2 can optionally be designed as sun protection or for full blackout.

Die zwischen den beiden Glasscheiben 1, 2 angeordnete Rolloeinrichtung der Ausführungsform nach den Fig. 1 bis 3 weist ein Wickelrohr 4 auf, auf welchem das Rollo 5 (Folie) durch Kleben befestigt und aufgewickelt ist. Das Wickelrohr 4 ist über eine vorgespannte Torsionsfeder 6 mit einer Achse 7 verbunden, wobei ein Ende der Torsionsfeder 6 an der Innenwand des Wickelrohrs 4 befestigt ist.The roller blind device of the embodiment according to FIGS. 1 to 3 arranged between the two glass panes 1, 2 has a winding tube 4, on which the roller blind 5 (film) is fastened and wound by gluing. The winding tube 4 is connected to an axle 7 via a prestressed torsion spring 6, one end of the torsion spring 6 being fastened to the inner wall of the winding tube 4.

Am freien vorderen Ende des Rollos 5 ist ein Zugstab 8 befestigt. Der Zugstab 8 ist an seinen beiden Enden jeweils mit einem Zahnriemen 9a, 9b verbunden. Die Zahnriemen 9a, 9b laufen jeweils über ein Zahnriemenrad 10a bzw. 10b, das mit der über die ganze Fensterbreite durchlaufende Achse 7 des Wikkelrohrs 4 befestigt sind. Außerdem läuft der Zahnriemen 9a über ein Zahnriemenrad 11a, das von einem Elektromotor 12 antreibbar ist. Der andere Zahnriemen 9b läuft in ähnlicher Weise über ein weiteres Zahnriemenrad 11b. Sowohl das Zahnriemenrad 11a wie auch das Zahnriemenrad 11b sind jeweils in einer Spanneinheit 13a bzw. 13b gelagert, so daß die Zahnriemen 9a, 9b jeweils für einen schlupffreien Betrieb unter der erforderlichen Spannung stehen. Eine der beiden Spanneinheiten, die Spanneinheit 13a, ist in Figur 3 in ihren Einzelheiten dargestellt.At the free front end of the blind 5, a pull rod 8 is attached. The tension rod 8 is connected at both ends to a toothed belt 9a, 9b. The toothed belts 9a, 9b each run over a toothed belt wheel 10a or 10b, which are fastened with the axis 7 of the winding tube 4 which extends over the entire window width. In addition, the toothed belt 9a runs over a toothed belt wheel 11a, which can be driven by an electric motor 12. The other toothed belt 9b similarly runs over another toothed belt wheel 11b. Both the toothed belt wheel 11a and the toothed belt wheel 11b are each mounted in a tensioning unit 13a or 13b, so that the toothed belts 9a, 9b are each under the required tension for slip-free operation. One of the two clamping units, the clamping unit 13a, is shown in detail in FIG.

Der Zahnriemen 9a wird also über das vom Motor 12 angetriebene Zahnriemenrad 11a angetrieben und treibt das Zahnriemenrad 10a auf der Achse 7 an. Der Zahnriemen 9b wird über das auf der Achse 6 sitzende andere Zahnriemenrad 10b angetrieben und nimmt das Zahnriemenrad 11b mit.The toothed belt 9a is thus driven by the toothed belt wheel 11a driven by the motor 12 and drives the toothed belt wheel 10a on the axis 7. The toothed belt 9b is driven by the other toothed belt wheel 10b seated on the axis 6 and takes the toothed belt wheel 11b with it.

Der Zugstab 8 wird also je nach Drehrichtung des Motors 12 von den Zahnriemen 9a, 9b nach oben oder unten bewegt.The tension rod 8 is thus moved up or down by the toothed belts 9a, 9b depending on the direction of rotation of the motor 12.

Die eine Spanneinheit 13a ist in Figur 3 in ihren Einzelheiten dargestellt. Danach ist die Zahnriemenscheibe 11a in einem Kunststofformteil 14 gelagert. Das Kunststofformteil 14 ist relativ zu einem Träger 15 verschiebbar und hat ein Langloch 16, durch das ein am Träger 15 befestigter Stift 17 hindurchverläuft. Zwischen diesem Stift 17 und einem am unteren Ende des Kunststofformteils 14 befestigten Stift 18 verläuft eine Zugfeder 19, die das Kunststofformteil 14 und damit die Zahnriemenscheibe 11a relativ zum Träger 15 nach oben vorspannt.One clamping unit 13a is shown in detail in FIG shown. Thereafter, the toothed belt pulley 11a is mounted in a molded plastic part 14. The molded plastic part 14 is displaceable relative to a carrier 15 and has an elongated hole 16 through which a pin 17 fastened to the carrier 15 extends. A tension spring 19 runs between this pin 17 and a pin 18 fastened to the lower end of the plastic molded part 14, which biases the plastic molded part 14 and thus the toothed belt pulley 11a upward relative to the carrier 15.

Besondere Bedeutung kommt der Anordnung des Wickelrohrs 4 auf der Achse 7 zu. Die Achse 7 ist, wie aus Figur 1 hervorgeht, mittels Kugellagern 20a, 20b, 20c und 20d gelagert. Das Wikkelrohr 4 ist auf der Achse 7 drehbar angeordnet und, wie schon erwähnt, mit diesem über die Torsionsfeder 6 verbunden. Auf der Achse 7 sitzen also die beiden Zahnriemenscheiben 10a und 10b drehfest und drehen sich spielfrei mit, während das Wickelrohr 4 mit Drehspiel auf der Achse sitzt und durch die Torsionsfeder 6 vorgespannt ist. Die Torsionsfeder 6 dient lediglich dazu, den sich beim Ab- und Aufwickeln des Rollos 5 ändernden Wickeldurchmesser auf dem Wickelrohr 4 während der gleichmäßigen Verschiebungsbewegung des Zugstabes 8 auszugleichen. Denn wenn das Rollo 5 ganz abgewickelt ist, ist der Wickeldurchmesser auf dem Wickelrohr 4 am geringsten und bei ganz aufgewickeltem Rollo am größten, weshalb die Drehbewegung des Wickelrohrs nicht vollständig synchron mit der Verschiebebewegung des Zugstabs 8 erfolgt.The arrangement of the winding tube 4 on the axis 7 is of particular importance. As can be seen in FIG. 1, the axis 7 is supported by means of ball bearings 20a, 20b, 20c and 20d. The winding tube 4 is rotatably arranged on the axis 7 and, as already mentioned, connected to it via the torsion spring 6. Thus, the two toothed belt pulleys 10a and 10b sit on the axis 7 in a rotationally fixed manner and rotate with no play, while the winding tube 4 sits on the axis with rotational play and is prestressed by the torsion spring 6. The torsion spring 6 only serves to compensate for the changing winding diameter on the winding tube 4 during the winding and unwinding of the roller blind 5 during the uniform displacement movement of the pull rod 8. Because when the roller blind 5 is completely unwound, the winding diameter on the winding tube 4 is the smallest and, when the roller blind is fully wound, the largest, which is why the rotational movement of the winding tube is not completely synchronized with the displacement movement of the pull rod 8.

Figur 4 zeigt eine abgewandelte Ausführungsform der Rolloeinrichtung, wobei der Mechanismus zur Bewegung des Zugstabs 8 anders ausgebildet ist. Wie bei der in den Figuren 1 bis 3 dargestellten Ausführungsform weist die zwischen den beiden Glasscheiben 1, 2 angeordnete Rolloeinrichtung ein Wickelrohr 4 auf, auf welchem das Rollo 5 (Folie) durch Kleben befestigt und aufgewickelt ist, und das über eine vorgespannte Torsionsfeder 6 mit einer Achse 7 verbunden ist. Das freie vordere Ende des Rollos 5 ist wiederum mit einem Zugstab 8 verbunden.FIG. 4 shows a modified embodiment of the roller blind device, the mechanism for moving the pull rod 8 being designed differently. As in the embodiment shown in FIGS. 1 to 3, the roller blind device arranged between the two glass panes 1, 2 has a winding tube 4, on which the roller blind 5 (film) is fastened and wound by gluing, and this with a prestressed torsion spring 6 an axis 7 is connected. The free front end of the blind 5 is in turn connected to a pull rod 8.

Statt über Zahnriemen wie bei der Ausführungsform nach den Figuren 1 bis 3 erfolgt bei der Ausführungsform nach Figur 4 der Transport des Zugstabs 8 mittels zweier Gewindespindeln 21a, 21b, mit welchen der Zugstab 8 durch Gewindemuttern 22a bzw. 22b verbunden ist. Die Lagerungen der Gewindespindeln 21a, 21b ist aus vereinfachungsgründen nicht dargestellt.Instead of using toothed belts as in the embodiment according to FIGS. 1 to 3, in the embodiment according to FIG. 4 the tension rod 8 is transported by means of two threaded spindles 21a, 21b, to which the tension rod 8 is connected by means of threaded nuts 22a and 22b. The bearings of the threaded spindles 21a, 21b are not shown for reasons of simplification.

Die Antriebsverbindung zwischen den beiden Gewindespindeln 21a, 21b und der das Wickelrohr 4 tragenden Achse 7 erfolgt über Kegelradgetriebe 23a bzw. 23b. Dementsprechend ist auch der Elektromotor 12 mit seiner Abtriebswelle über ein Kegelradgetriebe 23c mit dem entsprechenden Ende der einen Gewindespindel 21a gekuppelt. Es versteht sich, daß die Welle des Elektromotors 12 auch durchgehend ausgebildet sein kann und auch mit der anderen Gewindespindel 21b mit einem entsprechenden Kegelradgetriebe gekuppelt sein kann.The drive connection between the two threaded spindles 21a, 21b and the axis 7 carrying the winding tube 4 takes place via bevel gear transmissions 23a and 23b. Accordingly, the electric motor 12 is also coupled with its output shaft via a bevel gear 23c to the corresponding end of the one threaded spindle 21a. It goes without saying that the shaft of the electric motor 12 can also be continuous and can also be coupled to the other threaded spindle 21b with a corresponding bevel gear.

Die Ausführungsform nach Figur 4 hat den Vorteil, daß keine Spannmechanismen notwendig sind, wie bei der mit Zahnriemen arbeitenden Version nach den Figuren 1 bis 3, und daß die Ausführungsform mit Gewindespindeln den räumlichen Gegebenheiten in dem Zwischenraum zwischen den beiden Glasscheiben auf einfache Weise gerecht wird.The embodiment according to FIG. 4 has the advantage that no tensioning mechanisms are necessary, as in the version with toothed belts according to FIGS. 1 to 3, and that the embodiment with threaded spindles easily meets the spatial conditions in the space between the two glass panes ,
