Description

Die Erfindung richtet sich auf eine Gelenkarmmarkise mit wenigstens zwei Gelenkarmen, wobei jeder Gelenkarm einen inneren und einen äußeren Gelenkarmabschnitt umfaßt, die über ein Schwenkgelenk miteinander verbunden sind, wobei zwischen dem inneren und äußeren Gelenkarmabschnitt eine Gasfeder angeordnet ist, die den Gelenkarm in Richtung auf eine gestreckte Position beaufschlagt. Eine derartige Gelenkarmmarkise ist beispielsweise aus DE 296 12 532 U1 bekannt.The invention is directed to an articulated arm awning with at least two Articulated arms, each articulated arm having an inner and an outer Articulated arm section includes which are connected to one another via a swivel joint are, between the inner and outer articulated arm portion a gas spring is arranged that the articulated arm in the direction of a stretched position. Such an articulated arm awning is known for example from DE 296 12 532 U1.

Bei Gelenkarmmarkisen der in Betracht stehenden Art läßt sich eine Markise um so leichter ausfahren, je höher die durch die Gasfedern aufgebrachte Ausdrucksspannung bei der Abwärtsbewegung der Markise ist, zu welcher sich die in Ausfahrrichtung wirkende Schwerkraftkomponente addiert.With articulated arm awnings of the type in question, an awning can be The easier it is to extend, the higher the pressure applied by the gas springs Expressive tension in the downward movement of the awning is to which the gravity component acting in the extension direction is added.

Umgekehrt ist beim Aufwickeln der Markise gegen diese Ausdrucksspannung und gegen diese Schwerkraftkomponente eine Kraft aufzubringen, die das Aufwickeln des Markisentuches erschwert.The opposite is true when winding up the awning against this expressive tension and to apply a force against this component of gravity that it is difficult to wind up the awning cover.

Hiervon ausgehend liegt der Erfindung die Aufgabe zugrunde, eine Gelenkarmmarkise mit Gasfedern so auszugestalten, daß optimierte Kräfteverhältnisse beim Aus- und Einfahren und ein vorteilhaftes Aufwickelverhalten des Markisentuches bei hoher Windstabilität erreicht werden. Proceeding from this, the object of the invention is an articulated arm awning design with gas springs so that optimized balance of power when extending and retracting and an advantageous winding behavior of the awning fabric with high wind stability.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß Gasfedern eingesetzt werden, die eine derartige Kraft-Weg-Kennlinie aufweisen, daß die Federkraft in Ausfahrrichtung anders ist als in Einfahrrichtung, insbesondere niedriger.This object is achieved in that gas springs are used be that have such a force-displacement characteristic that the Spring force in the direction of extension is different than in the direction of entry, in particular lower.

Vorteilhafterweise ist vorgesehen, daß die Kennlinie so ausgebildet ist, daß ausgehend von dem vollständig ausgefahrenen Zustand der Markise die Einschubkraft zunächst sehr hoch ist, wodurch einerseits eine sehr hohe Windstabilität und andererseits ein optimales Aufrollverhalten in dieser Phase erreicht wird. Nach einer bestimmten Einfuhrstrecke wird die Einschubkraft dann stufenweise reduziert.It is advantageously provided that the characteristic curve is designed such that based on the fully extended condition of the awning Insertion force is initially very high, which on the one hand makes it very high Wind stability and on the other hand an optimal roll-up behavior in this Phase is reached. After a certain import route, the insertion force then gradually reduced.

Nachfolgend wird die Erfindung anhand eines bevorzugten Ausführungsbeispiels in Verbindung mit der Zeichnung näher erläutert. Dabei zeigen:

The invention is explained in more detail below on the basis of a preferred exemplary embodiment in conjunction with the drawing. Show:
Fig. 1
is a schematic, perspective view of an articulated arm awning with gas springs and
Fig. 2
an example of a displacement-force characteristic curve of a gas spring that can be used according to the invention.

Die in der Zeichnung dargestellte Markise weist eine an einer Hauswand oder dergleichen zu befestigende Trageinrichtung 1 auf, die mit einer in Lagerplatten 2,3 drehbar gelagerten Wickelwelle 4 versehen ist. Diese Wickelwelle 4 ist in bekannter Weise drehantreibbar, und zwar gemäß der Darstellung in Fig. 1 mittels eines selbsthemmenden Getriebes 5, das wiederum über eine ein- bzw. aushängbare Kurbelstange 6 antreibbar ist. Anstelle des Getriebes 5 mit Kurbelstange 6 kann selbstverständlich auch - wie allgemein bekannt - ein elektromotorischer Antrieb, ein Gurtantrieb oder dergleichen eingesetzt werden. Als Teil der Trageinrichtung 1 ist weiterhin zwischen den Lagerplatten 2 und 3 ein Tragrohr 7 mit quadratischem Querschnitt angebracht, an dem mittels jeweils einer Halte- und Neigungs-Verstell-Einrichtung 8 Gelenkarme 9 in sogenannter Scherenausführung angebracht sind. Diese Gelenkarme 9 sind jeweils in ihrer Mitte geteilt und mit einem Schwenkgelenk 10 mit vertikaler Achse versehen. Die Geelenkarme 9 sind jeweils mit einem gleichartigen Schwenkgelenk 11 an der entsprechenden Einrichtung 8 und - in der Zeichnung nicht erkennbar - mit einem entsprechenden Schwenkgelenk an einem Ausfallrohr 12 angelenkt, so daß das Ausfallrohr 12 in einer mit der Wickelwelle 4 gemeinsamen Ebene verschoben werden kann, aber keine Bewegungen senkrecht zu dieser Ebene ausführen kann.The awning shown in the drawing has one on a house wall or the like to be fastened support device 1, which with a Bearing plates 2,3 rotatably mounted winding shaft 4 is provided. This Winding shaft 4 is rotatably drivable in a known manner, specifically according to Representation in Fig. 1 by means of a self-locking gear 5, which in turn can be driven via a crank rod 6 which can be hooked in or out. Instead of the gear 5 with crank rod 6 can of course also - how generally known - an electric motor drive, a belt drive or the like are used. As part of the support device 1 is still between the bearing plates 2 and 3, a support tube 7 with a square cross section attached to which by means of a holding and tilt adjustment device 8 articulated arms 9 in a so-called scissors version are attached. These articulated arms 9 are each divided in the middle and provided with a swivel joint 10 with a vertical axis. The arms of the joints 9 are each with a similar pivot joint 11 on the corresponding device 8 and - not visible in the drawing - with a corresponding swivel joint is articulated on a drop pipe 12, so that the drop tube 12 in a common with the winding shaft 4 Plane can be moved, but no movements perpendicular to this Level can execute.

An der Wickelwelle 4 ist ein rechteckiges Markisentuch 13 befestigt, das durch die geschilderten Drehungen der Wickelwelle 4 auf diese auf- bzw., von dieser abgewickelt werden kann. Das Markisentuch 13 ist weiterhin in allgemein bekannter Weise an dem Ausfallrohr 12 festgelegt. An dem Ausfallrohr 12 ist ein nach unten hängender Volant 14 befestigt.On the winding shaft 4, a rectangular awning cloth 13 is attached, the due to the described rotations of the winding shaft 4 on this, can be handled by this. The awning cloth 13 is still in generally known manner set on the drop pipe 12. On the drop pipe 12, a valance 14 hanging down is attached.

Die Gelenkarme 9 weisen einen inneren Gelenkarmabschnitt 15 und einen äußeren Gelenkarmabschnitt 16 auf wobei jeweils eine Gasfeder 17 (in der Zeichnung nur schematisch angedeutet) Zwischen den beiden Gelenkarmabschnitten 15,16 das Schwenkgelenk 10 überbrückend angeordnet ist.The articulated arms 9 have an inner articulated arm section 15 and one outer articulated arm section 16, each with a gas spring 17 (in the Drawing only indicated schematically) Between the two articulated arm sections 15, 16 arranged the swivel joint 10 bridging is.

Die verwendeten Gasfedern 17 weisen eine in Fig. 2 dargestellte Kraft-Weg-Kennlinie derart auf, daß die Ausschubkraft beim Ausfahren entsprechend dem Kennlinienteil 18 in Fig. 2 kleiner ist als die Kraft beim Einfahren entsprechend dem Kennlinienteil 19 in Fig. 2.The gas springs 17 used have a force-displacement characteristic shown in FIG. 2 such that the extension force when extending the characteristic part 18 in FIG. 2 is smaller than the force when retracting corresponding to the characteristic part 19 in FIG. 2.

Die Kennlinie ist dabei so ausgebildet, daß ausgehend von der durch den Punkt 20 markierten, voll ausgefahrenen Position die Einschubkraft zunächst sehr hoch ist und erst nach einer bestimmten Einfahrwegstrecke in zwei Stufen 21, 22 auf ein niedrigeres Niveau abgesenkt wird, bis schließlich bei dem Punkt 23 der vollständig eingefahrene Zustand erreicht wird.The characteristic curve is designed such that, starting from the through the Point 20 marked, fully extended position the insertion force initially is very high and only after a certain entry route in two stages 21, 22 is lowered to a lower level until finally at point 23 the fully retracted state is reached.
