Abstract

A drop-arm awning or a blind is provided with a rotatably mounted, driveable cloth shaft, on which an awning cloth fastened thereto at the ends is wound. The drop arms (12) of the awning are mounted in two pivoting bearings (11) and carry at their free end a drop-out rod, to which the front edge of the awning cloth is fastened. Each drop-out arm is provided with a coil spring (22) for prestressing the drop-out arms in the swung-out direction. To design the pivoting bearing (11) as small as possible and avoid rubbing parts, the transverse and radial forces in the pivoting bearing (11) are transmitted solely via the coil spring (22). <IMAGE>

Description

Die Erfindung geht aus von einer Markise mit den Merkmalen des Oberbegriffs des Anspruches 1.The invention relates to an awning with the features of the preamble of claim 1.

Aus der DE-OS 33 44 359 ist eine gattungsgemäße Markisolette bekannt, die unterhalb der Wickelwelle zwei parallel mit Abstand zueinander verlaufende vertikale Führungsschienen enthält, die beidseits neben dem Fenster eines Gebäudes anzubringen sind. Auf den beiden Führungsschienen laufen zwei Führungsschlitten, die an ihrem oberen Ende über eine drehbar gelagerte Umlenkrolle für das Markisentuch miteinander verbunden sind. Jeder der Führungsschlitten trägt an seinem unteren Ende ein Scharniergelenk für einen Ausfallarm, der mit Hilfe einer Spiralfeder in Richtung auf die Ausklappstellung vorgespannt ist. Die freien Enden der beiden Ausfallarme sind durch die Ausfallstange, an der das freie Ende des Markisentuches angebracht ist, ebenfalls miteinander verbunden.From DE-OS 33 44 359 a generic Markisolette is known which contains below the winding shaft two vertical guide rails running parallel and at a distance from each other, which are to be attached on both sides next to the window of a building. Two guide slides run on the two guide rails, which are connected to each other at their upper end via a rotatably mounted deflection roller for the awning fabric. Each of the guide slides carries on his lower end a hinge joint for a drop arm, which is biased towards the unfolded position by means of a spiral spring. The free ends of the two extension arms are also connected to each other by the extension rod to which the free end of the awning cover is attached.

Mit Hilfe der beiden Spiralfedern soll erreicht werden, daß beim Ausfahren des Markisentuches im Anschluß an den maximal möglichen Abwärtshub der Führungsschlitten die Ausfallarme auszuschwenken beginnen, um das Markisentuch, das unter der Umlenkrolle vorläuft, schräg nach außen von dem Fenster weg auszustellen.With the help of the two spiral springs, the aim is to ensure that when the awning cover is extended following the maximum possible downward stroke of the guide slides, the extension arms begin to swing out so that the awning cover, which runs under the deflection roller, is tilted outwards away from the window.

Die Scharniergelenke für die Ausfallarme bestehen aus einem an dem Führungsschlitten befestigten Lagerzapfen, auf dem der jeweilige Ausfallarm mit einer entsprechenden Bohrung schwenkbar sitzt. Die Spiralfeder ist daneben angeordnet und übernimmt keinerlei Radialkräfte, denn diese werden ausschließlich von der Bohrung in dem Ausfallarm auf den Lagerzapfen übertragen. Diese Konstruktion ist in der Praxis sehr weit verbreitet, beansprucht aber erheblichen Platz in seitlicher Richtung, weil die Feder neben dem Scharniergelenk sitzt. Bei Markisoletten an kleinen Zimmerfenstern wirkt die Anordnung zu klobig.The hinge joints for the drop arms consist of a bearing pin fastened to the guide slide, on which the respective drop arm is pivotably seated with a corresponding bore. The coil spring is arranged next to it and does not take on any radial forces, because these are only transmitted from the hole in the extension arm to the bearing journal. This construction is very widespread in practice, but takes up considerable space in the lateral direction because the spring sits next to the hinge joint. The arrangement looks too bulky when it comes to markisolettes on small room windows.

Bei einer anderen Ausführungsform einer Markise nach der DE-OS 36 42 873 wurde deswegen versucht, die Größe des Gelenkes dadurch zu verkleinern, daß zum Vorspannen des Ausfallarmes eine in dem Ausfallarm sitzende Gasfeder verwendet wird, die mit Hilfe eines um das Scharniergelenk herumgeführten Seils wiederum den Ausfallarm in Ausklapprichtung vorspannt. Diese Konstruktion benötigt zwar weniger Platz, ist aber wegen der notwendigen Gasfeder technisch sehr anspruchsvoll.In another embodiment of an awning according to DE-OS 36 42 873 an attempt was therefore made to reduce the size of the joint by using a gas spring seated in the extension arm to pretension the extension arm, which in turn is carried out with the aid of a rope guided around the hinge joint preloads the extension arm in the direction of extension. These Although construction takes up less space, it is technically very demanding due to the gas spring required.

Ausgehend hiervon ist es Aufgabe der Erfindung, eine Markise zu schaffen, bei der das Schwenklager für den Ausfallarm nur sehr kleine Abmessungen aufweist und ohne komplizierte Teile auskommt.Proceeding from this, it is an object of the invention to provide an awning in which the pivot bearing for the drop arm has only very small dimensions and does not require any complicated parts.

Diese Aufgabe wird erfindungsgemäß durch die Markise mit den Merkmalen des Anspruches 1 gelöst.This object is achieved by the awning with the features of claim 1.

Weil die Spiralfeder dazu verwendet wird, sowohl das Drehmoment zum Ausschwenken des Ausfallarmes zu erzeugen als auch als Einrichtung um die Radialkräfte zu übertragen, wird ein eigenes Scharniergelenk entbehrlich. Die Abmessungen des Schwenklagers vermindern sich gegenüber den bekannten Anordnungen entsprechend dem nicht mehr benötigten Scharniergelenk. Gleichzeitig entfallen alle Lagerflächen, so daß die aus ästhetischen Gründen bessere Lösung auch den Vorteil der längeren Lebensdauer und der erhöhten Zuverlässigkeit hat, weil das Schwenklager keine aufeinander gleitenden Lagerflächen mehr aufweist, die wegen der Anordnung im Freien und dem Fehlen von Dichtungen einem erhöhten Verschleiß ausgesetzt wären.Because the coil spring is used both to generate the torque for swinging out the extension arm and as a device for transmitting the radial forces, a separate hinge joint is not necessary. The dimensions of the pivot bearing are reduced compared to the known arrangements in accordance with the hinge joint that is no longer required. At the same time, all of the bearing surfaces are eliminated, so that the solution, which is better for aesthetic reasons, also has the advantage of a longer service life and increased reliability, because the pivot bearing no longer has sliding bearing surfaces which are exposed to increased wear due to the arrangement outdoors and the lack of seals would be.

Eine besonders gute Seitenführung läßt sich erreichen, wenn die Spiralfeder als Bandspiralfeder ausgeführt ist, wodurch in seitlicher Richtung, also parallel zur Ausfallstange, größere Kräfte übertragen werden können.A particularly good lateral guidance can be achieved if the spiral spring is designed as a band spiral spring, as a result of which larger forces can be transmitted in the lateral direction, that is to say parallel to the drop rod.

Die Halterung und Montage der Spiralfeder kommt ohne Klemmeinrichtungen aus, wenn der Zapfen, auf dem die Spiralfeder sitzt, mit einer Öffnung zur Aufnahme des entsprechenden Endes versehen ist. Im Falle einer Bandspiralfeder ist diese Öffnung ein zu einem Ende des Lagerzapfens offener Schlitz, der ein leichtes Aufstecken der Spiralfeder gewährleistet.The mounting and mounting of the coil spring does not require any clamping devices if the pin on which the coil spring is seated is provided with an opening for receiving the corresponding end. In case of a Ribbon coil spring, this opening is a slot open to one end of the bearing journal, which ensures that the coil spring is easily attached.

Die Verbindung der Spiralfeder mit dem Ausfallarm ist ebenfalls sehr einfach, wenn das außen liegende Ende der Spiralfeder radial nach außen wegstehend abgewinkelt ist und dieses Ende in eine entsprechende Öffnung des Ausfallarmes eingesteckt ist.The connection of the spiral spring to the extension arm is also very simple if the outer end of the spiral spring is angled so as to protrude radially outwards and this end is inserted into a corresponding opening of the extension arm.

Zur Sicherung der Spiralfeder genügt ein einfacher selbstsichernder Wellensicherungsring, der auf den Lagerzapfen aufgeschoben ist. Dieser kann gegebenenfalls einstückig mit einer Kappe verbunden sein, um das freie Ende des Lagerzapfens abzuschließen.To secure the spiral spring, a simple self-locking shaft locking ring, which is pushed onto the bearing journal, is sufficient. This can optionally be connected in one piece with a cap in order to close off the free end of the bearing journal.

Die erfindungsgemäße Markise kann sowohl als Fallarmmarkise als auch als Markisolette ausgebildet sein. Im ersteren Falle sitzt das Schwenklager eines jeden Ausfallarmes ortsfest neben dem zu beschattenden Fenster, während im Falle der Markisolette neben dem Fenster zwei Führungsschienen vorgesehen sind, auf denen die Führungsschlitten laufen, die ihrerseits die Schwenklager für die Ausfallarme tragen. Dabei bleibt der filigrane Eindruck des neuen Schwenklagers erhalten, wenn der am unteren Ende des Bewegungshubs der Führungsschlitten vorgesehene Anschlag mit einer Drahtöse versehen ist, die mit dem am Ausfallarm vorgesehenen Bügel zusammenwirkt. Dieser Bügel hat zusammen mit der Öse die Aufgabe, dafür zu sorgen, daß beim Einfahren des Markisentuches zunächst die Ausfallarme entgegen der Wirkung der Spiralfedern an den Führungsschlitten herangeklappt werden, ehe die Aufwärtsbewegung des Führungsschlittens beim weiteren Einfahren des Markisentuches stattfindet. Dieser Bügel braucht keine allzu großen Kräfte zu übernehmen und kann folglich als Drahtbügel ausgebildet sein, wobei er in jedem Falle die Gestalt eines Kreisbogens hat, der konzentrisch zu dem Mittelpunkt der Spiralfeder liegt.The awning according to the invention can be designed both as a drop arm awning and as an awning isolate. In the former case, the swivel bearing of each extension arm is stationary next to the window to be shaded, while in the case of the marquette, two guide rails are provided next to the window on which the guide slides run, which in turn carry the swivel bearings for the extension arms. The filigree impression of the new swivel bearing is retained if the stop provided at the lower end of the movement stroke of the guide carriage is provided with a wire eyelet which interacts with the bracket provided on the extension arm. Together with the eyelet, this bracket has the task of ensuring that when the awning cover is retracted, the extension arms are first folded against the action of the spiral springs on the guide carriage before the guide carriage moves upwards when the awning cover is retracted further. This bracket does not have to take on excessive forces and can therefore be designed as a wire bracket, in any case it has the shape of an arc that is concentric with the center of the coil spring.

In the drawing, an embodiment of the object of the invention is shown. Show it:

the lower end of a guide carriage of the marrow isolette according to FIG. 1, with an exploded view of the pivot bearing.

In Fig. 1 ist eine Markisolette 1 veranschaulicht, die vor einem Fenster 2 eines nicht weiter gezeigten Gebäudes angebracht ist und in einem nach unten offenen Kasten 3 eine nicht weiter sichtbare Wickelwelle enthält, auf die ein Markisentuch 4 aufwickelbar ist, das mit seiner Hinterkante an der Wickelwelle befestigt ist. Unterhalb der Wickelwelle sind auf der Wand des Gebäudes neben dem Fenster 2 zwei rohrförmige Führungsschienen 5 und 6 befestigt, die parallel und im Abstand zueinander vertikal verlaufen. Die beiden Führungsschienen 5 und 6 werden an ihrem unteren, der Unterkante des Fensters 2 benachbarten Ende durch Wandhalter 7 festgehalten, während das obere Ende mit dem Kasten 3 verbunden ist.In Fig. 1, an awning isolate 1 is illustrated, which is attached in front of a window 2 of a building, not shown, and in a box 3 open at the bottom contains a winding shaft (not visible), onto which an awning cloth 4 can be wound, with its rear edge on the winding shaft is attached. Below the winding shaft on the wall of the building next to the window 2, two tubular guide rails 5 and 6 are attached, which run parallel and at a distance from each other vertically. The two guide rails 5 and 6 are held at their lower end adjacent to the lower edge of the window 2 by wall brackets 7, while the upper end is connected to the box 3.

Die beiden Führungsschienen 5 und 6 dienen der verschieblichen Lagerung zweier untereinander gleicher, jedoch zueinander spiegelbildlicher Führungsschlitten 8, an deren oberem Ende eine Umlenkrolle 9 drehbar gelagert ist, die sich zwischen den beiden Führungsschlitten 8 erstreckt. Das untere Ende jedes der beiden Führungsschlitten 8 trägt ein Schwenklager 11, über das schwenkbar je ein Ausfallarm 12 mit dem zugehörigen Führungsschlitten 8 verbunden ist. Die Schwenkachsen der beiden Schwenklager 11 liegen aus gleicher Höhe und fluchten miteinander, d.h. sie liegen auf einer gemeinsamen Geraden, die zu der Achse der Wickelwelle bzw. der Umlenkrolle 9 parallel ist.The two guide rails 5 and 6 are used for the displaceable mounting of two mutually identical but mutually mirror-image guide carriages 8, at the upper end of which a deflection roller 9 is rotatably mounted, which extends between the two guide carriages 8. The lower end of each of the two guide carriages 8 carries a pivot bearing 11, via which a drop arm 12 is pivotally connected to the associated guide carriage 8. The pivot axes of the two pivot bearings 11 lie at the same height and are aligned with one another, i.e. they lie on a common straight line which is parallel to the axis of the winding shaft or the deflection roller 9.

Mit den freien Enden der Ausfallarme 12 ist eine Ausfallstange 13 verbunden, an der die Vorderkante des Markisentuches 4 verankert ist.With the free ends of the drop arms 12, a drop bar 13 is connected to which the front edge of the awning fabric 4 is anchored.

Die Markisolette 1 in Fig. 1 ist in einer teilweise ausgefahrenen Stellung gezeigt, bei der die beiden Führungsschlitten 8 ihre unterste Stellung auf den Führungsschienen 5, 6 erreicht haben und die beiden parallel im Abstand zueinander verlaufenden Ausfallarme 12 von dem Fenster 2 wegstehend herausgeschwenkt sind. Das Markisentuch 4 verläuft deswegen zwischen dem Kasten 3 und der Umlenkrolle 9 etwa vertikal und von der Umlenkrolle 9 ausgehend bis hin zu der Ausfallstange 13 schräg nach unten von dem Fenster 2 weg.The Markisolette 1 in Fig. 1 is shown in a partially extended position, in which the two guide carriages 8 their lowest position on the Have reached guide rails 5, 6 and the two parallel extending arms 12 are pivoted out away from the window 2. The awning cloth 4 therefore runs between the box 3 and the deflecting roller 9 approximately vertically and starting from the deflecting roller 9 up to the drop bar 13 obliquely downwards from the window 2.

Das Schwenklager 11 des Führungsschlittens 8, der auf der Führungsschiene 5 läuft, ist in den Fig. 2 und 3 im einzelnen dargestellt. Das Schwenklager 11 des anderen Führungsschlittens 8, der auf der Führungsschiene 6 längsverschieblich geführt ist, ist spiegelsymmetrisch ausgeführt, so daß die nachstehend gegebene Beschreibung auch für das andere Schwenklager gilt.The pivot bearing 11 of the guide carriage 8, which runs on the guide rail 5, is shown in FIGS. 2 and 3 in detail. The pivot bearing 11 of the other guide carriage 8, which is guided in a longitudinally displaceable manner on the guide rail 6, is mirror-symmetrical, so that the description given below also applies to the other pivot bearing.

Der Führungsschlitten 8 weist an seinem unteren Ende eine mit zwei zueinander parallelen Durchgangsbohrungen 14 und 15 versehene Muffe 16 auf, die zwischen den beiden Bohrungen 14 und 15 stegförmig verjüngt ist. Durch die Bohrung 14 hindurch läuft die Führungsschiene 5 mit geringem Spiel, so daß die Muffe 16 leicht auf der Führungsschiene 5 hin- und herverschiebbar ist. In der Bohrung 15 steckt dagegen festgeklemmt eine zylindrische Strebe 17, die zu einer oberen Führungsmuffe 18 führt, an der die Umlenkrolle 9 drehbar gelagert ist. Auch die Führungsmuffe 18 ist leicht mit geringem Spiel auf der Führungsschiene 5 hin- und herverschiebbar. Der Abstand der Muffen 16 und 18 ist etwas größer als die Ausfallarme 12 lang sind.The guide carriage 8 has at its lower end a sleeve 16 provided with two mutually parallel through bores 14 and 15, which is tapered in the form of a web between the two bores 14 and 15. The guide rail 5 runs through the bore 14 with little play, so that the sleeve 16 can be easily pushed back and forth on the guide rail 5. In contrast, a cylindrical strut 17 is clamped in the bore 15 and leads to an upper guide sleeve 18, on which the deflection roller 9 is rotatably mounted. The guide sleeve 18 can also be easily pushed back and forth on the guide rail 5 with little play. The distance between the sleeves 16 and 18 is slightly larger than the extension arms 12 are long.

Die Führungsmuffe 16 trägt einen zylindrischen Lagerzapfen 19, dessen Längsachse rechtwinklig zu einer Ebene verläuft, die die Längsachsen der beiden Bohrungen 14 und 15 enthält. Der Lagerzapfen 19 kragt einseitig vor und geht an seinem der Muffe 16 benachbarten Ende in eine plane Ringschulter 21 über. Er dient als Sitz für eine Bandspiralfeder 22, deren innenliegendes Ende 23 radial nach innen und deren äußeres Ende 24 radial nach außen wegstehend abgebogen ist. Mit dem inneren Abschnitt 23 greift die Spiralfeder 22 in einen Längsschlitz 25 des Lagerzapfens 19. Der Längsschlitz 25 ist zu dem freien Ende des Lagerzapfens 19 hin offen und zeigt in Richtung auf die Bohrung 15. Die Weite des Schlitzes 25 entspricht der Materialstärke der Spiralfeder 22, die etwa drei bis vier Gänge aufweist.The guide sleeve 16 carries a cylindrical bearing pin 19, the longitudinal axis of which is perpendicular to a plane which contains the longitudinal axes of the two bores 14 and 15. The bearing pin 19 protrudes on one side and goes on the sleeve 16 adjacent to it End in a flat annular shoulder 21. It serves as a seat for a coil spring 22, the inner end 23 of which is bent radially inward and the outer end 24 projecting radially outward. With the inner section 23, the coil spring 22 engages in a longitudinal slot 25 of the bearing pin 19. The longitudinal slot 25 is open to the free end of the bearing pin 19 and points in the direction of the bore 15. The width of the slot 25 corresponds to the material thickness of the coil spring 22 , which has about three to four courses.

Zwecks besserer seitlicher Führung ist zwischen der Ringschulter 21 und der Spiralfeder 22 eine Beilagscheibe 26 angeordnet und außerdem befindet sich auf der von der Muffe 16 abliegenden Seite der Spiralfeder 22 eine weitere Beilagscheibe 27, die dieselben Abmessungen wie die Beilagscheibe 26 hat. Die axiale Sicherung der Beilagscheiben 26 und 27 sowie der Spiralfeder 22 auf dem Lagerzapfen 19 übernimmt ein Sicherungselement 28, das nach Art einer selbstsperrenden Sicherungsscheibe ausgebildet ist, die einstückig angeformt eine kalottenförmige Kappe 29 trägt.For the purpose of better lateral guidance, a washer 26 is arranged between the annular shoulder 21 and the spiral spring 22 and there is also a further washer 27 on the side of the spiral spring 22 remote from the sleeve 16, which has the same dimensions as the washer 26. The axial securing of the washers 26 and 27 as well as the spiral spring 22 on the bearing journal 19 is carried out by a securing element 28, which is designed in the manner of a self-locking locking washer, which integrally formed on a dome-shaped cap 29.

Auf den Abschnitt 24 der Spiralfeder 22 steckt mit einem entsprechenden Schlitz der Ausfallarm 12. Der Schlitz ist aus Darstellungsgründen in den Figuren nicht ersichtlich; stattdessen ist der Abschnitt 24 in Fig. 2 gestrichelt veranschaulicht. Mittels eines muffenartigen Stellrings 31 wird der Schlitz nach dem Einführen des Abschnittes 24 zusammengepreßt, um eine reibschlüssige Verbindung zwischen dem Abschnitt 24 und dem Ausfallarm 12 herzustellen.The extension arm 12 is placed on the section 24 of the spiral spring 22 with a corresponding slot. For reasons of illustration, the slot is not shown in the figures; instead, section 24 is illustrated in dashed lines in FIG. 2. By means of a sleeve-like adjusting ring 31, the slot is pressed together after the section 24 has been inserted in order to establish a frictional connection between the section 24 and the extension arm 12.

Außerdem sitzt in dem Stellring 31 in zwei zueinander parallelen Bohrungen ein Drahtbügel 32, der zwei zueinander parallele Schenkel 33 und 34 aufweist, die an ihrem von dem Ausfallarm 12 abliegenden Ende bei 35 einstückig miteinander verbunden sind. Der Drahtbügel 32 hat den Verlauf eines Kreisbogens, der bei montiertem Schwenklager 11, wie Fig. 2 erkennen läßt, zu der Achse des Lagerzapfens 19 konzentrisch ist.In addition, in the adjusting ring 31, a wire bracket 32 is seated in two mutually parallel bores, which has two mutually parallel legs 33 and 34, which are integrally connected at 35 at their end remote from the extension arm 12. The wire bracket 32 has the shape of a circular arc which, when the pivot bearing 11 is mounted, as can be seen in FIG. 2, is concentric with the axis of the bearing pin 19.

Die tiefste Stelle, die der Führungsschlitten 8 auf der jeweiligen Führungsschiene 5, 6 erreichen kann, wird durch einen Stellring 36 definiert, der mittels einer Klemmschraube 37 an der entsprechenden Stelle auf der Führungsschiene 5 bzw. 6 festgeklemmt wird. Am Ende seines Bewegungswegs stößt der Führungsschlitten 8 mit der Spiralfeder 22 auf eine Drahtöse 38 des Stellringes 36 auf, wodurch eine weitere Abwärtsbewegung begrenzt ist. Die Drahtöse 38 steht radial von der Führungsschiene 5 bzw. 6 weg und ihr Abstand von dem Lagerzapfen 39 ist derart bemessen, daß wenn die Spiralfeder 22 auf der Öse 38 aufsteht, er genauso groß ist wie der Krümmungsradius des Bügels 32. Die Öse 38 liegt parallel zu den Lagerzapfen.The deepest point that the guide carriage 8 can reach on the respective guide rail 5, 6 is defined by an adjusting ring 36, which is clamped by means of a clamping screw 37 at the corresponding point on the guide rail 5 or 6. At the end of its movement path, the guide slide 8 with the coil spring 22 strikes a wire eyelet 38 of the adjusting ring 36, as a result of which further downward movement is limited. The wire eyelet 38 stands radially away from the guide rail 5 or 6 and its distance from the bearing pin 39 is dimensioned such that when the spiral spring 22 stands on the eyelet 38, it is the same size as the radius of curvature of the bracket 32. The eyelet 38 lies parallel to the trunnion.

Die insoweit beschriebene Markise 1 funktioniert in folgender Weise: Wenn zunächst angenommen ist, daß die Markise 1 vollständig eingefahren ist, so sind die beiden Ausfallarme 12 vertikal nach oben geschwenkt, wobei die Ausfallstange 13 knapp unterhalb der Umlenkrolle 9 verläuft. Außerdem liegen die Muffen 18 der beiden Führungsschlitten 8 an der oberen Befestigung der beiden Führungsschienen 5, 6 an.The awning 1 described so far works in the following way: If it is initially assumed that the awning 1 is completely retracted, the two extension arms 12 are pivoted vertically upwards, the extension rod 13 running just below the deflection roller 9. In addition, the sleeves 18 of the two guide carriages 8 rest on the upper fastening of the two guide rails 5, 6.

Wenn, ausgehend von dieser Stellung, das Markisentuch 4 von der Wickelwelle abgewickelt wird, laufen zunächst die beiden Führungsschlitten 8 auf den Führungsschienen 5 und 6 nach unten, solange, bis die am Führungsschlitten 8 unten befindliche Muffe 16 auf dem jeweils zugehörigen Stellring 36 aufsteht. Um ein Schiefziehen zu vermeiden, sind die beiden Stellringe 36 auf den beiden Führungsschienen 5 und 6 in gleicher Höhe montiert.If, starting from this position, the awning fabric 4 is unwound from the winding shaft, the two guide carriages 8 first run on the guide rails 5 and 6 downwards until the sleeve 16 located at the bottom of the guide carriage 8 stands on the respective adjusting ring 36. In order to avoid skewing, the two adjusting rings 36 are mounted on the two guide rails 5 and 6 at the same height.

Sobald die Führungsschlitten 8 auf den Stellringen 36 aufstehen und das Markisentuch 4 weiter ausgefahren wird, werden die Ausfallarme 12 infolge der Rücksprungkraft der Bandspiralfeder 22 von der Wand weg nach außen geschwenkt. Hierbei gelangt der Drahtbügel 32 in die Drahtöse 38.As soon as the guide carriages 8 stand up on the adjusting rings 36 and the awning fabric 4 is extended further, the extension arms 12 are pivoted outwards away from the wall due to the resilience of the coil spring 22. In this case, the wire bracket 32 enters the wire eyelet 38.

Dabei wird nach dem Ausschwenken der Ausfallarme 12 das Markisentuch 4, das unter der Umlenkrolle 9 vorkommt, durch die Wirkung des Gewichts der Ausfallstange, 13 der beiden Ausfallarme 12 und des von den beiden Spiralfedern 22 erzeugten Drehmomentes gespannt gehalten, damit die in Fig. 1 erkennbare Stellung zustandekommt.After swiveling out the extension arms 12, the awning fabric 4, which occurs under the deflection roller 9, is held taut by the effect of the weight of the extension rod, 13 of the two extension arms 12 and the torque generated by the two coil springs 22, so that the in FIG. 1 recognizable position comes about.

Entsprechend dem Abwickeln des Markisentuches 4 schwenken die Ausfallarme 12 mehr oder weniger weit nach unten.According to the unwinding of the awning fabric 4, the extension arms 12 pivot more or less far down.

Zum Einfahren der Markise 1 wird das Markisentuch 4 wiederum auf die Wickelwelle aufgewickelt, wodurch eine Kraft zustandekommt, die bestrebt ist, die Führungsschlitten 8 auf den Führungsschienen 5 und 6 nach oben zu ziehen. An dieser Aufwärtsbewegung werden die Führungsschlitten 8 aber durch die beiden Bügel 32 gehindert, die in den Drahtösen 38 stecken. Beim Aufwickeln des Markisentuches 4 werden deswegen zunächst die Ausfallarme 12 entgegen der Schwerkraftwirkung und entgegen dem von den Spiralfedern 22 ausgeübten Drehmoment nach oben geschwenkt. Erst, wenn die Ausfallarme 12 fast vollständig nach oben geschwenkt sind, kommen an beiden Seiten die Drahtbügel 32 aus den Drahtösen 38 frei, so daß das Markisentuch 4 die Führungsschlitten 8 anheben kann. Zwar üben die nun stärker vorgespannten Spiralfedern 22 ein größeres Drehmoment auf die Ausfallarme 12 aus, doch das Gewicht der Führungsschlitten 8 samt den Ausfallarmen 12, der Ausfallstange 13 und der Umlenkrolle 9 genügt, um die Ausfallarme 12 entgegen der Wirkung der Spiralfedern 22 in der vertikalen Stellung zu halten.To retract the awning 1, the awning cloth 4 is again wound onto the winding shaft, whereby a force is generated which tends to pull the guide carriages 8 on the guide rails 5 and 6 upwards. However, the guide carriages 8 are prevented from this upward movement by the two brackets 32 which are inserted in the wire eyelets 38. When the awning fabric 4 is wound up, the extension arms 12 are therefore first pivoted upward against the force of gravity and against the torque exerted by the spiral springs 22. Only when the drop arms 12 are almost completely pivoted upwards come on both sides of the wire bracket 32 free from the wire eyelets 38 so that the awning cloth 4 can lift the guide carriage 8. Although the now more preloaded coil springs 22 exert a greater torque on the drop arms 12, the weight of the guide carriage 8 together with the drop arms 12, the drop rod 13 and the deflection roller 9 is sufficient to counter the action of the drop springs 12 in the vertical direction 22 Hold position.

Ersichtlicherweise sind die Ausfallarme 12 bei der Markise 1 ausschließlich über die Spiralfeder 22 mit den zugehörigen Führungsschlitten 8 verbunden. Die Spiralfeder 22 übernimmt bei jedem Führungsschlitten 8 deswegen auch die Übertragung der Quer- bzw. Zugkräfte zu bzw. von dem jeweiligen Ausfallarm 12. Eine unmittelbare Verbindung zwischen dem Lagerzapfen 19 und dem Ausfallarm 12 existiert nicht, so daß beim Schwenken der Ausfallarm 12 keine gleitende Reibung zwischen den Ausfallarmen 12 und den Lagerzapfen 19 auftritt. Die Beilagscheiben 26 und 27 dienen lediglich einer Verbesserung der seitlichen Führung der Spiralfedern 22 bzw. sie sollen ein Eindringen von Fremdkörpern zwischen die Lagen der Spiralfedern 22 verhindern. Durch geeignete Dimensionierung der Spiralfeder 22 bzw. der Lage des äußeren Abschnittes 24 gegenüber dem inneren Abschnitt 23 im entspannten Zustand kann erreicht werden, daß die Ausfallarme 12 auch im vollständig herausgeschwenkten Zustand noch ein zusätzliches Moment von den Spiralfedern 22 erteilt bekommen. Insofern ist die in Fig. 3 gezeigte Stellung der Spiralfeder 22 nicht der entspannte Zustand, sondern der zu der entsprechenden Stellung des Ausfallarmens 12 gehörende Zustand, in dem die Spiralfeder 22 vorgespannt ist.As can be seen, the extension arms 12 in the awning 1 are connected exclusively to the associated guide carriages 8 via the spiral spring 22. For each guide carriage 8, the spiral spring 22 therefore also takes over the transmission of the transverse or tensile forces to or from the respective extension arm 12. A direct connection between the bearing pin 19 and the extension arm 12 does not exist, so that when the extension arm 12 is pivoted no sliding Friction between the drop arms 12 and the bearing pin 19 occurs. The washers 26 and 27 are only used to improve the lateral guidance of the coil springs 22 and are intended to prevent foreign bodies from entering between the layers of the coil springs 22. By suitable dimensioning of the coil spring 22 or the position of the outer section 24 relative to the inner section 23 in the relaxed state, it can be achieved that the extension arms 12 are given an additional moment by the coil springs 22 even in the fully pivoted-out state. In this respect, the position of the coil spring 22 shown in FIG. 3 is not the relaxed state, but rather the state belonging to the corresponding position of the drop arm 12, in which the coil spring 22 is preloaded.
