Abstract

An articulated-arm awning with a load-bearing framework in which an awning-canvas shaft is mounted rotatably, with articulated arms mounted pivotably in brackets, and with an opening-out rod which tensions the end of the canvas and is connected in an articulated manner to the lower arm of the articulated arm. The technical problem is increasing the opening-out length while maintaining the stability of an articulated-arm awning. At least one arm (upper arm 4 and/or lower arm 5) of each articulated arm (3) forms, in the stretched-out position, an essentially right angle with the opening-out rod (7) and has a telescoping device which is prestressed in the opening-out direction. <IMAGE>

Description

Die Erfindung betrifft eine Gelenkarmmarkise mit einem Traggestell, in dem eine Tuchwelle drehbar gelagert ist, mit in Konsolen schwenkbar gelagerten Gelenkarmen und mit einer das Tuchende spannenden Ausfallstange, die gelenkig mit den Unterarmen der Gelenkarme verbunden ist, wobei mindestens ein Arm jedes Gelenkarmes in der Streckstellung einen im wesentlichen rechten Winkel mit der Ausfallstange bildet.The invention relates to an articulated arm awning with a support frame, in which a cloth shaft is rotatably supported, in consoles swivel-mounted articulated arms and with an exciting the cloth end Extension bar, which is articulated to the forearms of the articulated arms is, wherein at least one arm of each articulated arm in the extended position forms a substantially right angle with the extension rod.

Die FR-A-2 163 097 beschreibt eine Gelenkarmmarkise der genannten Art. Jeder Arm eines Gelenkarms besteht aus zwei ineinander steckenden Profilstücken, die jedoch nicht gegeneinander verschiebbar sind. Die DE-A-3 243 025 beschreibt ebenfalls eine Gelenkarmmarkise der genannten Art, die zum Spannen der Gelenkarme Gasdruckfedern vorsieht. Die Oberarme und Unterarme der Gelenkarme haben in jedem Fall eine feste, unveränderliche Länge.FR-A-2 163 097 describes an articulated arm awning of the aforementioned Art. Each arm of an articulated arm consists of two nested ones Profile pieces, which however cannot be moved against each other. The DE-A-3 243 025 also describes an articulated arm awning of the type mentioned Type that provides gas springs for tensioning the articulated arms. The Upper arms and forearms of the articulated arms always have a fixed, constant length.

Da die Gelenkarme zusammengeklappt werden, ist die Ausfallänge derartiger Markisen konstruktiv etwa auf die Länge der Gelenkarme beschränkt.Since the articulated arms are folded, the drop lengths are Such awnings are limited in construction to the length of the articulated arms.

Die Verwendung von Teleskopstangen anstelle von Gelenkarmen führt auch nicht weiter, da die Teleskopstangen in der Einfahrstellung parallel zum Traggestell liegen und somit ebenfalls nur eine begrenzte Ausfahrlänge zu Verfügung steht. Die Teleskopstangen schließen immer einen spitzen Winkel mit der Ausfallstange ein. Dieses begrenzt die Stabilität der Anordnung. Wenn die Teleskopstangen an dem Traggestell zentral angelenkt werden, ergibt sich sogar eine instabile Dreieckanordnung.The use of telescopic rods instead of articulated arms leads also not further, since the telescopic rods are parallel in the retracted position lie to the support frame and thus also only a limited one Extend length is available. The telescopic rods always close an acute angle with the drop bar. This limits the Stability of the arrangement. When the telescopic poles on the support frame are articulated centrally, there is even an unstable triangle arrangement.

Aufgabe der Erfindung ist die Vergrößerung der Ausfallänge bei Beibehaltung der Stabilität einer Gelenkarmmarkise. The object of the invention is to enlarge the drop lengths Maintaining the stability of an articulated arm awning.

Diese Aufgabe wird nach der Erfindung dadurch gelöst, daß mindestens ein Arm (Oberarm und/oder Unterarm) jedes Gelenkarmes eine in Ausfallrichtung vorgespannte Teleskopeinrichtung aufweist.This object is achieved according to the invention in that at least one arm (upper arm and / or forearm) of each articulated arm a telescopic device biased in the direction of failure having.

Die Erfindung unterscheidet sich insofern vom Stand der Technik, als diese Ausrichtung eines Armes ein teleskopisches Ausfahren der Markise unter Beibehaltung der Geometrie der Gelenkarme ermöglicht. Man hat dadurch eine hohe Stabilität der Kraftaufnahme unter günstigen Winkeln. Da der Ausfall der Markise größer als die Länge der nicht teleskopierten Gelenkarme ist, kann der Ausfall größer als die Breite der Markise sein. Dieses ist besonders bei schmalen Loggien von Bedeutung.The invention differs from the prior art in that than this alignment of an arm is a telescopic Extension of the awning while maintaining the geometry the articulated arms enables. You have a high stability of the Force absorption at favorable angles. Because the awning failed is greater than the length of the non-telescopic articulated arms, the Failure to be larger than the width of the awning. This is special important for narrow loggias.

Derarige Markisen mit Teleskoparmen sind wesentlich windstabiler, da die vergleichsweise trägen Gasdruckfedern der Teleskopeinrichtungen Aufbeulungen des Markisentuches unter Windbelastungen stark dämpfen. Dadurch werden besonders die Gelenke geschont. Die Gasdruckfedern stellen auch in ausgefahrenem Zustand der Markise eine große Spannkraft für das Markisentuch zur Verfügung. Dies gilt umsomehr, wenn die Gelenke in Streckstellung verriegelt sind. Die Teleskopeinrichtung wirkt im wesentlichen senkrecht zur Ausfallstange, so daß die Kraftmomente immer gleich sind. Die Teleskopeinrichtung übt keine Kräfte senkrecht zur Ausfallrichtung auf das Markisentuch aus, so daß dasselbe immer gleichmäßig gespannt ist.Such awnings with telescopic arms are much more wind stable, because the comparatively slow gas springs of the telescopic devices Strongly dampen the bulge of the awning fabric under wind loads. This protects the joints in particular. The gas pressure springs provide great tension even when the awning is extended available for the awning cover. This applies all the more if the Joints are locked in the extended position. The telescopic device acts essentially perpendicular to the drop rod, so that the moments of force are always the same. The telescopic device exerts no forces perpendicular to the drop direction on the awning fabric, so that the same is always evenly tensioned.

Eine Ausführungsbeispiel sieht vor, daß die Teleskopeinrichtung in dem Oberarm angeordnet ist.An embodiment provides that the telescopic device is arranged in the upper arm.

Eine besonders hohe Stabilität ergibt sich dadurch, daß die Teleskopeinrichtung in dem Unterarm angeordnet ist.A particularly high stability results from the fact that the telescopic device is arranged in the forearm.

Eine spielfreie Teleskopführung erhält man dadurch, daß die Teleskopeinrichtung zwei gleitend ineinander verschiebbare rohrartige Profilteile umfaßt.A play-free telescopic guide is obtained in that the telescopic device two tubular profile parts that can be slid into each other includes.

Eine kleinvolumige Betätigungseinrichtung erzielt man dadurch, daß eine Feder, vorzugsweise eine Gasdruckfeder zur Vorspannung der Teleskopeinrichtung vorgesehen ist.A small-volume actuating device can be achieved that a spring, preferably a gas pressure spring for biasing the Telescopic device is provided.

Dammit die Teleskopeinrichtung nur in der Streckstellung wirksam ist, ist vorgesehen, daß eine in der Streckstellung selbstauslösende Entriegelungsvorrichtung für die Teleskopeinrichtung vorgesehen ist. Dadurch wird eine Betätigung der Teleskopeinrichtung in einer Knicklage verhindert. Dieses könnte zu undefinierbaren Betriebszuständen und instabilen statischen Bedingungen führen.So that the telescopic device is only effective in the extended position is, it is provided that a self-triggering in the stretched position Unlocking device is provided for the telescopic device. This causes an actuation of the telescopic device in a kink position prevented. This could lead to indefinable operating states and unstable static conditions.

Eine sichere Sperre des Gelenks in der Streckstellung wird dadurch erzielt, daß als Sperrvorrichtung im Unterarm eine in eine Ausnehmung des Oberarms eingreifende Stange mit einem Betätigungshebel vorgesehen ist, der von der Teleskopeinrichtung in der Einfahrstellung betätigt wird.This will securely lock the joint in the extended position achieved that as a locking device in the forearm in a recess of the upper arm engaging rod with an operating lever is provided by the telescopic device in the retracted position is operated.

Definierte Betriebsverhältnisse für die Teleskopeinrichtung werden dadurch sichergestellt, daß für das Gelenk eine in der Streckstellung wirksame Sperrvorrichtung vorgsehen ist.Defined operating conditions for the telescopic device thereby ensuring that for the joint one in the extended position effective locking device is provided.

Ein sicheres Einfahren der Markise wird dadurch gewährleistet, daß eine beim Einfahren des Tuches wirksame Knickauslösevorrichtung für jedes Gelenk vorgesehen ist.A safe retraction of the awning is guaranteed that an effective kink release device when retracting the cloth is provided for each joint.

Eine einfache Knickauslösevorrichtung ist als Stange ausgebildet.A simple kink release device is designed as a rod.

Die Unterarme 5 tragen eine Ausfallstange 7, an der das Tuch 2 befestigt ist. In Ausfallstellung bilden die Unterarme 5 mit der Ausfallstange 7 einen im wesentlichen rechten Winkel. Dieses ist für die Kräfteverhältnisse sehr günstig. Die Gelenkarme 3 sind durch nicht dargestellte Zugelemente in Ausfallrichtung vorgespannt, damit das Tuch 2 immer gespannt gehalten ist. Da die Gelenkarme 3 zusammenklappen, ist die Ausfahrlänge dieser herkömmlichen Markisenanordnung etwa auf die Länge eines Gelenkarms beschränkt.

The telescopic device is biased in the failure direction, which will be explained in more detail becomes. The telescopic device is in the extended position of the articulated arms Approved. In the extended position, the joints 6, their Legs 4, 5 form an acute angle with each other, against each other locked. So you get constant and reproducible power relationships.

    Fig. 3 zeigt ein weiteres Beispiel der Erfindung. Dort stehen die Schenkel 4, 5 der Gelenkarme 3 in der Streckstellung unter einen gestreckten Winkel, so daß die Gelenkarme eine Totpunktstellung einnehmen. Es ist auch eine Übertotpunktstellung möglich. Aus dem Vergleich der Fig. 2 und 3 mit Fig. 1 erkennt man deutlich den durch die Erfindung erzielten technischen Effekt. Die Ausfahrlänge der Markise ist wensetlich größer als die gestreckte Länge eines Gelenkarms.3 shows another example of the invention. They are there Legs 4, 5 of the articulated arms 3 in the extended position under an extended one Angle so that the articulated arms assume a dead center position. An over-center position is also possible. From the comparison 2 and 3 with Fig. 1 can be clearly seen by the invention achieved technical effect. The extension length of the awning is significantly larger than the extended length of an articulated arm.

    Die Fig. 4 bis 6 zeigen Einzelheiten der Teleskopeinrichtung. Der Unterarm 5 umfaßt ein Innenprofil 8 und ein Außenprofil 9. Das Innenprofil 8 nimmt auf einem Zapfen 11 einen Bügel 10 auf, an dem die Ausfallstange 7 befestigt ist. Das Innenprofil 8 und das Außenprofil 9 sind durch die Kolbenstange 16 einer Gasdruckfeder 17 miteinander gekoppelt.4 to 6 show details of the telescopic device. Of the Forearm 5 comprises an inner profile 8 and an outer profile 9. The inner profile 8 takes on a pin 11 on a bracket 10 on which the drop rod 7 is attached. The inner profile 8 and the outer profile 9 are coupled to one another by the piston rod 16 of a gas pressure spring 17.

    Das Innenprofil 8 und das Außenprofil 9 weisen fluchtend aufeinander ausrichtbare Durchgänge 12, 13 auf, in die ein Bolzen 13 als Sperrvorichtung eingreift. Der Bolzen 13 sitzt an einer federnden Zunge 14 mit Anschlagnasen 15. Die Zunge 14 ist an dem Innenprofil 8 befestigt und in Sperrstellung vorgespannt, so daß normalerweise bei eingeknicktem Gelenkarm der Zapfen 13 in die Durchgänge 12, 21 eingreift und die Teleskopeinrichtung verriegelt. In der Streckstellung gemäß Fig 5 und 6 stoßen die Anschlagnasen 15 an dem Bügel 10 an, so daß der Zapfen 13 aus den Durchgängen 12, 21 herausgehoben wird und die Teleskopeinrichtung entriegelt. Die Gasdruckfeder 17 ist dann wirksam und fährt über die Kolbenstange 16 die Telekopeinrichtung aus.The inner profile 8 and the outer profile 9 face each other in alignment alignable passages 12, 13 into which a bolt 13 as Locking device engages. The bolt 13 sits on a resilient tongue 14 with stop lugs 15. The tongue 14 is fastened to the inner profile 8 and biased in the locked position, so that normally at the articulated arm of the pin 13 engages in the passages 12, 21 and locks the telescopic device.
