Abstract

The linkage arms for an awning have arm sections (2) and joints (5,9) with structured dimensions and positions so that a lateral force is applied to a sliding tilting rod, which is parallel to the deployment profile (11) or building wall when it is operated. The bearing side of the tilting rod is pushed against a spring (18) towards the lateral force which engages/disengages a coupling (10) and disengages a coupling (19) through a force which overcomes the spring for the tilting rod to swing on a horizontal axis. When the deployment profile is extended, the coupling (19) is engaged and the swing movement is blocked.

Ausgehend von einer derartigen bekannten Konstruktion liegt der Erfindung die Aufgabe zugrunde, einen möglichst einfachen, funktionssicheren, herstellungstechnisch leicht realisierbaren Aufbau zu erzielen.The invention is based on such a known construction based on the task of creating the simplest, most reliable, to achieve a construction that is easy to implement in terms of production technology.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß die Gelenkarm-Abschnitte und Gelenke derart dimensioniert und positioniert sind, daß auf eine quer verschiebbar gelagerte Kippwelle eine Querkraft parallel zum Ausfallprofil bzw. zur Gebäudewand ausgeübt wird, wenn das Ausfallprofil eingefahren wird, daß das die lagerseitige Kippwelle gegen die Kraft einer Feder in Richtung der Querkraft verschiebbar gelagert ist, daß eine in Abhängigkeit von dieser Verschiebung aktivierbare und deaktivierbare Kupplung derart vorgesehen ist, daß bei eingefahrenem Ausfallprofil und dementsprechend die Kraft der Feder übersteigender Querkraft die Kupplung ausgekuppelt ist und ein Verschwenken der Kippwelle um eine horizontale Schwenkachse ermöglicht und bei ausgefahrenem Ausfallprofil die Kupplung eingekuppelt ist und das Verschwenken blockiert.This object is achieved in that the articulated arm sections and joints are dimensioned and positioned so that on a transversely displaceable tilting shaft a transverse force parallel to Failure profile or to the building wall is exercised if the failure profile is retracted that the bearing-side tilt shaft against the force a spring is slidably mounted in the direction of the transverse force that a in Depending on this shift can be activated and deactivated Coupling is provided such that when the failure profile is retracted and accordingly the force of the spring exceeding the transverse force of the clutch is disengaged and a pivoting of the tilt shaft about a horizontal Swivel axis enables and with the extension profile extended Coupling is engaged and the pivoting blocked.

Erfindungsgemäß macht man sich also die sich ändernden Querkraft-Verhältnisse während des Ausfahrens bzw. beim Einfahren des Markisentuches zunutze, um eine einfache und zuverlässige Arretierung und ein Schutz gegen Windböen im ausgefahrenen Zustand und einen raumsparenden Aufbau im eingefahrenen Zustand zu erzielen.According to the invention, the changing shear force ratios are thus made while extending or retracting the awning cover take advantage of a simple and reliable locking and a Protection against wind gusts when extended and a space-saving To achieve construction when retracted.

In weiterer Ausgestaltung der Erfindung ist vorgesehen, daß der innere Gelenkarm-Abschnitt länger ist als der äußere Gelenkarm-Abschnitt, wodurch die gewünschte definierte Querkraftänderung bewerkstelligt bzw. unterstützt wird.In a further embodiment of the invention it is provided that the inner articulated arm section which is longer than the outer articulated arm section accomplishes or supports the desired defined shear force change becomes.

Vorteilhafterweise ist vorgesehen, daß die Kippwelle im Bereich des Konsole an zwei voneinander beabstandeten Lagerringen gelagert ist, und daß die Feder durch eine Schraubenfeder gebildet ist, welche zwischen den Lagerringen auf der Kippwelle angeordnet ist.It is advantageously provided that the tilting shaft in the area of the console is mounted on two spaced apart bearing rings, and that the spring is formed by a coil spring which is between the bearing rings is arranged on the tilting shaft.

Zur Erzielung eines definierten Verschiebeweges in Querrichtung können beiderseits des einen Lagerrings zwei Anschlagringe vorgesehen sein.To achieve a defined displacement in the transverse direction two stop rings can be provided on both sides of the one bearing ring.

Nach einer bevorzugten Ausführungsform ist die Kupplung durch einen drehfest mit der Kippwelle verbundenen Kupplungsring mit sich axial erstreckenden Kupplungsansätzen und durch drehfeste Kupplungsausnehmungen gebildet. Sobald die Ansätze in die Ausnehmungen eingreifen, wird eine Schwenkbewegung unterbunden, während bei herausbewegten Ansätzen eine freie Schwenkbewegung möglich ist. According to a preferred embodiment, the clutch is by a Coupling ring connected to the tilt shaft in a rotationally fixed manner with itself axially extending coupling approaches and by non-rotatable coupling recesses educated. As soon as the lugs engage in the recesses, a pivoting movement is prevented, while when moving out Approaches a free swivel movement is possible.

Die Kupplungsausnehmungen sind günstigerweise an der Außenseite des Lagerrings ausgebildet, so daß hierfür kein zusätzliches Bauteil erforderlich ist.The coupling recesses are conveniently on the outside of the Bearing rings formed so that no additional component is required for this is.

Eine in der Zeichnung dargestellte erfindungsgemäße Gelenkarm-Markise umfaßt zwei Gelenkarme 1, wobei jeder Gelenkarm 1 gebildet ist durch einen inneren, längeren Gelenkarm-Abschnitt 2 und einen äußeren, kürzeren Gelenkarm-Abschnitt 3, welche untereinander mittels eines Gelenkes 4 mit vertikaler Schwenkachse verbunden sind. Der innere Gelenkarm-Abschnitt 2 ist über ein Gelenk 5 mit vertikaler Gelenkachse 6 mit einem Kippgelenk 7 verbunden, welches an einer Konsole 8 angeordnet ist, die ihrerseits an einer (in der Zeichnung nicht dargestellten) Wand befestigt ist. An articulated arm awning according to the invention shown in the drawing comprises two articulated arms 1, each articulated arm 1 being formed by an inner, longer articulated arm section 2 and an outer, shorter one Articulated arm section 3, which mutually by means of a joint 4th are connected to the vertical swivel axis. The inner articulated arm section 2 is connected via a joint 5 with a vertical joint axis 6 to a Tilt joint 7 connected, which is arranged on a console 8, the is in turn attached to a wall (not shown in the drawing).

Der äußere Gelenkarm-Abschnitt 3 ist mit seinem äußeren Ende über ein Gelenk 9 mit vertikaler Schwenkachse 10 mit einem Ausfallprofil 11 verbunden, wobei der Abstand I der beiden Gelenkachsen konstant ist ebenso wie der Abstand m zwischen den beiden an der Wand befestigten Haltekonsolen 8.The outer articulated arm section 3 is at one end with its outer end Joint 9 with vertical pivot axis 10 connected to a drop profile 11, the distance I between the two joint axes is also constant like the distance m between the two wall brackets 8th.

Das in Fig. 3 und 4 näher dargestellte Kippgelenk 7 umfaßt eine Kippwelle 12, an welcher im Bereich ihres in der Zeichnung rechten äußeren Endes das Schwenklager 5 ausgebildet ist. Die Kippwelle 12 ist an der Konsole über zwei im Abstand voneinander angeordnete Lager 13, 14 quer, d.h. in Richtung der Längsachse 15 der Kippwelle 12 verschiebbar gelagert, wobei die Verschiebebewegung nach links durch einen Anschlagring 16 begrenzt wird. Ein weiterer Anschlagring 17 ist an der Innenseite des Lagers 14 auf der Kippwelle 12 befestigt. Zwischen diesem Anschlagring 17 und dem Lager 13 ist auf der Kippwelle 12 eine Schraubenfeder 18 angeordnet, die sich einerseits an dem Anschlagring 17 und andererseits an der Innenseite des Lagers 13 abstützt.The tilt joint 7 shown in FIGS. 3 and 4 comprises a tilt shaft 12, at which in the area of their right outer end in the drawing the pivot bearing 5 is formed. The tilt shaft 12 is on the console across two spaced apart bearings 13, 14, i.e. in Direction of the longitudinal axis 15 of the tilt shaft 12 is slidably mounted, wherein the movement to the left is limited by a stop ring 16 becomes. Another stop ring 17 is on the inside of the bearing 14 the tilt shaft 12 attached. Between this stop ring 17 and the Bearing 13 is arranged on the tilt shaft 12, a coil spring 18, the on the one hand on the stop ring 17 and on the other hand on the inside of the bearing 13 is supported.

Eine Kupplungseinrichtung 19 wird gebildet durch einen Kupplungsring 20, der am freien äußeren Ende der Kippwelle 12 sitzt. An der Innenseite des Kupplungsrings 20 sind sich in axialer Richtung erstreckende Kupplungsansätze 21 vorgesehen (vgl. insbesondere Fig. 3), welche in dem in Fig. 4 dargestellten eingekuppelten Zustand in korrespondierende Kupplungsansatz-Ausnehmungen 22 eingreifen, so daß ein Verdrehen der Kippwelle 12 relativ zu den Lagern 13, 14 bzw. zu den Konsolen 8 unterbunden wird, wohingegen eine solche Schwenkbewegung in Richtung des Pfeils 23 um die Längsachse bzw. Schwenkachse 15 möglich ist, wenn der Kupplungsring 20 mit den Kupplungsansätzen 21, wie in Fig. 3 dargestellt, um eine Strecke S zusammen mit der Kippwelle 12 nach links verschoben ist, wobei diese Verschiebung (in der Zeichnung nach links) durch den Anschlagring 16 (vgl. Fig. 3) und die Verschiebung in die Gegenrichtung, also in der Zeichnung nach rechts, durch den Anschlagring 17 begrenzt wird.A coupling device 19 is formed by a coupling ring 20, which sits at the free outer end of the tilt shaft 12. On the inside the coupling ring 20 are coupling lugs extending in the axial direction 21 provided (cf. in particular Fig. 3), which in the Fig. 4 shown coupled state in corresponding coupling lug recesses 22 engage so that twisting of the tilt shaft 12 relative to the bearings 13, 14 or to the brackets 8 prevented whereas such a pivoting movement in the direction of arrow 23 around the longitudinal axis or pivot axis 15 is possible if the coupling ring 20 with the coupling lugs 21, as shown in Fig. 3 to a distance S is shifted to the left together with the tilting shaft 12, this shift (to the left in the drawing) by the stop ring 16 (see FIG. 3) and the displacement in the opposite direction, that is to the right in the drawing, is limited by the stop ring 17.

Der Zweck der vorstehend beschriebenen Ausgestaltung besteht darin, die Gelenkarme 1 der Markise im Bereich der Konsolen 8 um die Schwenkachse 15 schwenken zu lassen, damit im eingefahrenen Zustand eine möglichst geringe Baugröße erreicht wird. Hierfür wird eine in Richtung des Pfeils 24 wirkende Querkraft ausgenutzt, die aufgrund der unterschiedlichen Längenverhältnisse von innerem Gelenkarm-Abschnitt 2 und äußerem Gelenkarm-Abschnitt 3 im Zusammenwirken mit der Federkraft der Schraubenfeder 18 zu einer jeweils unterschiedlichen resultierenden Kraft in Abhängigkeit von dem Ausfahrzustand der Markise bzw. des Ausfallprofils 11 führt, und zwar unter Berücksichtigung des Umstandes, daß der Abstand m zwischen den Konsolen 8 und der Abstand I zwischen den Schwenkachsen 10 am Ausfallprofil 11 während der gesamten Bewegung konstant bleibt.The purpose of the configuration described above is to: Articulated arms 1 of the awning in the area of the brackets 8 about the pivot axis 15 to be swiveled so that when retracted one is possible small size is achieved. For this, one in the direction of arrow 24 acting transverse force exploited due to the different length ratios of inner articulated arm section 2 and outer articulated arm section 3 in cooperation with the spring force of the coil spring 18 depending on a different resultant force leads from the extended state of the awning or the drop profile 11, taking into account the fact that the distance m between the brackets 8 and the distance I between the pivot axes 10 on the drop profile 11 remains constant during the entire movement.

In der Zeichnung ist der Verlauf der Wirkungslinie 25 zwischen der Achse 10 des Schwenkgelenks 9 am Ausfallrohr und der Gelenkachse 6 des Gelenks 5 an der Kippwelle 12 an der Konsole 8 dargestellt. Hieraus ist erkennbar, daß aufgrund des flacheren Winkels dieser Wirkungslinie 25 relativ zur Achse 15 im eingefahrenen Zustand eine erheblich höhere Querkraft in Richtung des Pfeils 24 erzeugt wird (der die Federkraft in Richtung des Pfeils 26 entgegenwirkt) als in dem in Fig. 2 dargestellten ausgefahrenen Zustand. In the drawing, the course of the line of action 25 between the axis 10 of the swivel joint 9 on the drop tube and the joint axis 6 of the joint 5 shown on the tilting shaft 12 on the console 8. From this it can be seen that due to the flatter angle of this line of action 25 relative to axis 15 in the retracted state, a significantly higher lateral force is generated in the direction of arrow 24 (which the spring force in the direction of Arrow 26 counteracts) than in the extended shown in Fig. 2 Status.

Die auf die Kupplungseinrichtung 19 zwischen den Kupplungsansätzen 21 und Kupplungsausnehmungen 22 wirkende resultierende Kraft ist also im eingefahrenen Zustand am größten und wird geringer je weiter die Markise ausfährt.The on the coupling device 19 between the coupling lugs 21st and coupling recesses 22 resulting force is therefore im retracted state the largest and becomes smaller the further the awning extending.

Dementsprechend wird im eingefahrenen Zustand die Kippwelle 12 durch eine aus Querkraft und Federkraft resultierende Kraft nach außen bzw. in der Zeichnung nach links gedrückt und die Kupplung geöffnet, so daß eine Schwenkbewegung um die Achse 15 möglichst ist. Bei solchermaßen geöffneter Kupplung 19 könnte sich der jeweilige Gelenkarm 1 durch sein Eigengewicht und das des Ausfallprofils 11 nach unten um die Achse 15 der Kippwelle 12 bewegen, wenn das am Ausfallprofil 11 befestigte (in der Zeichnung nicht dargestellte) Markisentuch diese Bewegung nicht verhindern würde. Wenn das Markisentuch aber im Zuge des Ausfahrvorgangs von der Tuchwelle (in der Zeichnung ebenfalls nicht dargestellt) abgewickelt wird, können die Gelenkarme 1 aufgrund des Eigengewichts um die Achse 15 nach unten schwenken.Accordingly, the tilting shaft 12 is in the retracted state a force resulting from lateral force and spring force to the outside or in the drawing pressed to the left and the clutch opened so that a Pivotal movement about the axis 15 is possible. With this open Coupling 19 could be the respective articulated arm 1 through Dead weight and that of the drop profile 11 down around the axis 15 the tilt shaft 12 move when the attached to the drop profile 11 (in the Awning fabric (not shown) does not prevent this movement would. If the awning cover is in the course of the extension process unwound from the cloth shaft (also not shown in the drawing) is, the articulated arms 1 due to its own weight around the Swivel axis 15 down.

Um im letztendlich ausgefahrenen Zustand eine definierte Markisenneigung einstellen zu können und diese Einstellung auch gegenüber angreifenden Winden aufrechtzuhalten, muß die Kupplung 19 in diesem Zustand die Schwenkbewegung nach oben arretieren, was - wie erläutert - dadurch bewerkstelligt wird, daß mit zunehmendem Ausfahren der Markise die resultierende Kraft die Richtung ändert und die Kupplung durch die Kraft der Schraubenfeder 18 in den in Fig. 4 dargestellten Zustand gebracht wird, wo die Kupplungsansätze 21 in die Kupplungsausnehmungen 22 eingreifen und somit eine Schwenkbewegung unterbinden. Die Markise ist in diesem Zustand mit einem definierten Neigungswinkel gegen ein Hochschlagen durch angreifenden Wind gesichert.To achieve a defined awning inclination in the ultimately extended state to be able to adjust and this attitude also towards attacking To maintain winches, clutch 19 must be in this condition lock the swivel movement upwards, which - as explained - thereby is accomplished that with increasing extension of the awning resulting force changes direction and the clutch by force the coil spring 18 is brought into the state shown in FIG. 4, where the coupling lugs 21 engage in the coupling recesses 22 and thus prevent a pivoting movement. The awning is in this Condition with a defined angle of inclination against beating up secured by attacking wind.

Wird jetzt die Markise wieder eingefahren, vergrößert sich die Querkraft bis die Kraft der Schraubenfeder 18 überwunden und die Kupplung 19 durch eine Bewegung um den Abstand S geöffnet wird. Das Markisentuch zieht dementsprechend die Gelenkarme 1 um einen definierten Winkel nach oben, wobei diese Bewegung durch eine Drehbegrenzung mittels eines Sicherungsrings, im Ausführungsbeispiel gebildet durch den Anschlagring 17, begrenzt wird.If the awning is now retracted, the lateral force increases until the force of the coil spring 18 is overcome and the clutch 19 is opened by a movement by the distance S. The awning cloth accordingly pulls the articulated arms 1 by a defined angle above, this movement being limited by rotation by means of a locking ring, in the exemplary embodiment formed by the stop ring 17, is limited.

Das vorstehend beschriebene System eröffnet folgende Verstellmöglichkeiten:

  • Mittels des Anschlagrings 16 kann die Vorspannkraft der Schraubenfeder 18 am Kippgelenk 8 eingestellt werden
  • Mittels des Anschlagrings 16 ist es möglich, eine Schwenkbegrenzung der Kippwelle 12 nach oben vorzunehmen
  • Durch Auslegung des Kupplungsringes 20 für die gewünschte Neigung der Gelenkarme
  • Eine weitere Veränderung der Kräfteverhältnisse kann durch Änderung des Abstandes I der Gelenke 9 am Ausfallprofil 11 bewerkstelligt werden.
The system described above opens up the following adjustment options:
  • The prestressing force of the helical spring 18 on the tilt joint 8 can be adjusted by means of the stop ring 16
  • By means of the stop ring 16, it is possible to limit the pivoting of the tilting shaft 12 upwards
  • By designing the coupling ring 20 for the desired inclination of the articulated arms
