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.The invention relates to an articulated arm awning with a support frame, in which a fabric shaft is rotatably mounted, with articulated arms pivotably mounted in consoles and with an extension rod which excites the fabric end and is articulated to the lower arms of the articulated arms.

Die FR-A-2 163 091 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-2 163 091 describes an articulated arm awning of the type mentioned. Each arm of an articulated arm consists of two interlocking profile pieces which, however, cannot be displaced relative to one another. DE-A-3 243 025 also describes an articulated arm awning of the type mentioned, which provides gas pressure springs for tensioning the articulated arms. The upper arms and forearms of the articulated arms always have a fixed, unchangeable 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 of such awnings is limited in construction to approximately 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 does not help either, since the telescopic rods are parallel to the support frame in the retracted position and therefore only a limited extension length is available. The telescopic rods always form an acute angle with the drop rod. This limits the stability of the arrangement. If the telescopic rods are articulated centrally on the support frame, there is even an unstable triangular 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 while 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 in der Streckstellung einen im wesentlichen rechten Winkel mit der Ausfallstange bildet und eine in Ausfallrichtung vorgespannte Teleskopeinrichtung aufweist.This object is achieved according to the invention in that at least one arm (upper arm and / or lower arm) of each articulated arm in the extended position forms a substantially right angle with the extension rod and has a telescopic device that is biased in the direction of extension.

Die Erfindung unterscheidet sich insofern vom Stand der Technik, als diese Ausrichtung eines Armes senkrecht zur Ausfallstange 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 telespopierten 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 this alignment of an arm perpendicular to the extension bar enables the awning to be extended telescopically while maintaining the geometry of the articulated arms. This gives a high stability of the force absorption at favorable angles. Since the awning's dropout is greater than the length of the non-telescopic articulated arms, the dropout can be greater than the width of the awning. This is particularly important for narrow loggias.

Derarige Markisen mit Teleskoparmen sind wesentlich windstabiler, da die vergleichseweise 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 stable because the comparatively inert gas pressure springs of the telescopic devices strongly dampen bulges of the awning fabric under wind loads. This protects the joints in particular. The gas pressure springs provide great tension for the awning cover even when the awning is extended. 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 direction of failure on the awning fabric, so that the same is always tensioned evenly.

Eine Ausrührungsbeispiel siehr vor, daß die Teleskopeinrichtung in dem Oberarm angeordnet ist.An Ausrührungsbeispiel see before 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 comprises two tubular profile parts which can be slid into one another.

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

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, it is provided that a self-releasing unlocking device is provided for the telescopic device in the extended position. This prevents actuation of the telescopic device in a kink position. 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 eingereifende Stange mit einem Betätigungshebel vorgesehen ist, der von der Teleskopseinrichtung in der Einfahrstellung betätigt wird.A secure locking of the joint in the extended position is achieved in that a rod engaging in a recess in the upper arm is provided as an locking device in the forearm with an actuating lever which is actuated by the telescopic device in the retracted position.

Definierte Betriebverhältnisse 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 are ensured in that a locking device effective in the extended position is provided for the joint.

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 ensured by the fact that an effective kink release device is provided for each joint when the fabric is retracted.

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

Fig. 1 zeigt schematisch ein an einer Fassade oder einer Wand befestigtes Traggestell 1 mit einer nicht dargestellten Tuchwelle für ein Tuch 2. Das Traggestell 1 kann ein Tragrohr, einen Kasten und/oder Konsolen umfassen. In an der Fassade oder dem Traggestell befestigten Konsolen sitzen schwenkbar Gelenkarme 3, deren Oberarm 4 und Unterarm 5 durch ein Gelenk 6 miteinander gekoppelt sind. 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.1 schematically shows a support frame 1 fastened to a facade or a wall with a cloth shaft (not shown) for a cloth 2. The support frame 1 can comprise a support tube, a box and / or brackets. Articulated arms 3, whose upper arm 4 and forearm 5 are coupled to one another by a joint 6, are pivotably seated in brackets fastened to the facade or the supporting frame. The forearms 5 carry a drop bar 7 to which the cloth 2 is attached. In the down position, the forearms 5 form an essentially right angle with the down rod 7. This is very favorable for the balance of power. The articulated arms 3 are biased in the direction of failure by tension elements, not shown, so that the cloth 2 is always kept under tension. Since the articulated arms 3 fold together, the extension length of this conventional awning arrangement is approximately limited to the length of an articulated arm.

Fig 2 stellt ein Beispiel der Erfindung dar. Die Unterarme 5 enthalten jeweils eine Teleskopeinrichtung, indem ein Innenprofil 8 und ein Außenprofil 9 ineinander verschiebbar sind. Die Teleskopeinrichtung ist in Ausfallrichtung vorgespannt, was noch im Einzelnen erläutert wird. Die Teleskopeinrichtung wird in der Streckstellung der Gelenkarme freigegeben. In der Streckstellung sind die Gelenke 6, deren Schenkel 4, 5 einen spitzen Winkel miteinander bilden, gegeneinander verriegelt. So erhält man gleichbleibende und reproduzierbare Kräfteverhältnisse.2 shows an example of the invention. The forearms 5 each contain a telescopic device in that an inner profile 8 and an outer profile 9 can be moved into one another. The telescopic device is biased in the direction of failure, which will be explained in detail. The telescopic device is released in the extended position of the articulated arms. In the extended position, the joints 6, the legs 4, 5 of which form an acute angle with one another, are locked against one another. 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. There the legs 4, 5 of the articulated arms 3 are at an extended angle in the extended position, so that the articulated arms assume a dead center position. An over-center position is also possible. The technical effect achieved by the invention can be clearly seen from the comparison of FIGS. 2 and 3 with FIG. 1. The extension length of the awning is considerably longer 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. The forearm 5 comprises an inner profile 8 and an outer profile 9. The inner profile 8 receives a bracket 10 on a pin 11, to which the extension rod 7 is fastened. 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 have passages 12, 13 which can be aligned with one another and into which a bolt 13 engages as a locking device. The bolt 13 is seated on a resilient tongue 14 with stop lugs 15. The tongue 14 is fastened to the inner profile 8 and is pretensioned in the locked position, so that normally the pin 13 engages in the passages 12, 21 when the articulated arm is bent and the telescopic device is locked. 5 and 6, the stop lugs 15 abut the bracket 10, so that the pin 13 is lifted out of the passages 12, 21 and unlocks the telescopic device. The gas pressure spring 17 is then effective and extends the telescopic device via the piston rod 16.

In der Streckstellung ist das Gelenk 6 gesperrt, was weiter unten erläutert wird. Eine als Knickauslösevorrichtung wirksame Stange 18 ist in dem Außenprofil 9 geführt. Beim Einrollen des Tuches 2 werden die Teleskopeinrichtungen eingefahren und die Gasdruckfedern gespannt. Schließlich stößt das Innenrprofil 8 an die Stange 18, die das Gelenk 6 einknickt und als Knickauslösevorrichtung dient. Der Zapfen 13 greift in die Durchgänge 12 ein und sperrt die Teleskopeinrichtung.In the extended position, the joint 6 is locked, which is explained below. A rod 18 acting as a kink release device is guided in the outer profile 9. When the cloth 2 is rolled in, the telescopic devices are retracted and the gas pressure springs are tensioned. Finally, the inner profile 8 abuts the rod 18, which bends the joint 6 and serves as a kink release device. The pin 13 engages in the passages 12 and locks the telescopic device.

Die Fig. 7 und 8 zeigen ein Ausführungsbeipiel einer Sperrvorrichtung für das Gelenk 6. An der Aufnahme 19 des Unterarms 5 ist eine Stange 20 geführt, die durch einen Zapfen 22 mit einem Hebel 23 gekoppelt ist. Der Hebel 23 ist auf einem Bolzen 24 gelenkig geführt und durch eine Feder 25 vorgespannt. Ein Hebelkopf 26 kommt an der Stirnfläche des nichtdargestellten Innenprofils des Unterarms in Anlage, wodurch eine Betätigung der Sprrvorrichtung beim Einfahern der Teleskopeinrichtung erfolgt. Der Kopf 27 der Stange 20 greift in der streckstellung des Gelenkarms in eine Ausnehmung 28 der Aufnahme 29 des Oberarms 4 ein, so daß dadurch in der Streckstellung das Gelenk gesperrt ist.7 and 8 show an exemplary embodiment of a locking device for the joint 6. A rod 20 is guided on the receptacle 19 of the forearm 5 and is coupled to a lever 23 by a pin 22. The lever 23 is articulated on a bolt 24 and biased by a spring 25. A lever head 26 comes into contact with the end face of the inner profile of the forearm (not shown), as a result of which the sprayer is actuated when the telescopic device is retracted. The head 27 of the rod 20 engages in the extended position of the articulated arm in a recess 28 of the receptacle 29 of the upper arm 4, so that the joint is locked in the extended position.
