Description

Die vorliegende Erfindung befasst sich mit einer Sonnenschutzanlage für Außenanlagen wie eine Wintergartenmarkise, Senkrechtmarkise oder Fassadenmarkise.The present invention relates to a sun protection system for outdoor facilities such as a conservatory awning, vertical awning or facade awning.

Derartige Sonnenschutzanlagen, unter denen auch allgemein sonstige Verschattungs-, Verdunklungseinrichtungen oder auch Insektenschutzeinrichtungen zu verstehen sind, sind beispielsweise aus der DE 103 42 661 B3 bekannt. Es ist ein elektrischer Antrieb vorgesehen, mit dem ein Sonnenschutzrollo aus- und eingefahren werden kann.Such sun protection systems, which are generally also other shading, darkening or insect protection devices are to be understood, for example, from DE 103 42 661 B3 known. It is an electric drive provided with a sun protection blind can be extended and retracted.

Aus der DE 10 2004 017 459 A1 ist ein Sonnenschutzrollo für ein Schiebedachsystem bekannt. Es ist ein Rollo vorgesehen, dessen seitliche Längsränder mit seitlichen Federstahlbändern verbunden sind. Diese sind jeweils in einer Führungsschiene aufgenommen. Am vorderen Rand des Behangs ist dort ein Spriegel vorgesehen, der einem Ausfallprofil bei Sonnenschutzanlagen entspricht, mit Hilfe dessen das Rollo verschoben werden kann, d. h. die Ausfahrlänge einstellbar ist. Der Vorteil dieser Art von Verschattungseinrichtungen besteht darin, dass die seitlichen Federstahlbänder den Behang stabilisieren, gleichzeitig aber das Einrollen aufgrund ihrer besonderen Eigenschaften nicht behindern oder fördern. Die Führung in seitlichen Führungsschienen vermeidet auch einen seitlichen Stoffspalt, so dass mit derartigen Verschattungsvorrichtungen in Verbindung mit geeigneten Geweben oder Folien auch Räume verdunkelt werden können.From the DE 10 2004 017 459 A1 is a sun blind for a sunroof system known. There is provided a roller blind whose lateral longitudinal edges are connected to lateral spring steel strips. These are each accommodated in a guide rail. At the front edge of the curtain there is provided a bow, which corresponds to a front rail in sun protection systems, with the help of which the roller blind can be moved, ie the extension length is adjustable. The advantage of this type of shading devices is that the lateral spring steel strips stabilize the curtain, but at the same time not hinder or promote curling due to their special properties. The guide in side guide rails also avoids a lateral material gap, so that with such shading devices in conjunction with suitable tissues or films and rooms can be darkened.

Aus der DE 203 09 690 U1 ist ein Sonnenschutzrollo bekannt, das zur Verschattung von Kraftfahrzeugfenstern dient. Es weist ein Sonnenschutzrollo auf, dessen Längsränder mit Federstahlbändern verbunden sind, die in einer Führung geführt sind. Die Federstahlbänder sind gelocht, und in die Lochung greift ein Antriebszahnrad ein, das von einem Motor angetrieben wird.From the DE 203 09 690 U1 is a sunblind known, which is used for shading motor vehicle windows. It has a sunshade, whose longitudinal edges are connected to spring steel strips, which are guided in a guide. The spring steel bands are perforated, and in the perforation engages a drive gear, which is driven by a motor.

Die Aufgabe der vorliegenden Erfindung besteht darin, die aus dem Stand der Technik bekannten Sonnenschutzanlagen so weiterzubilden, dass sie für den Einsatz als Außenanlagen (z.B. Wintergartenmarkise, Senkrechtmarkise oder Fassadenmarkise) geeignet sind.The object of the present invention is to develop the sun protection systems known from the prior art so that they are suitable for use as outdoor installations (for example, conservatory awning, vertical awning or facade awning).

Erfindungsgemäß ist hierfür eine Sonnenschutzanlage für Außenanlagen wie eine Wintergartenmarkise, Senkrechtmarkise oder Fassadenmarkise vorgesehen, mit einem wickelbaren Behang, der an seinen beiden Seitenflanken mit Federstahlbändern verbunden ist, die in ersten Führungskammern in seitlichen Führungsschienen beweglich geführt sind und sich beim Einholen des Behangs mit diesem selbsttätig zusammenrollen, wobei ein Antrieb vorgesehen ist, der mit beiden Federstahlbändern gekoppelt ist und auf diese unmittelbar einwirkt, wobei der Antrieb auf die beiden Federstahlbänder in deren gestreckten Bereichen einwirkt und wobei am ausfahrbaren Ende des Behangs ein Fallprofil angeordnet ist, das mit den beiden Federstahlbändern verbunden istAccording to the invention a sun protection system for outdoor facilities such as a conservatory awning, vertical awning or façade awning is provided with a windable curtain, which is connected at its two side edges with spring steel bands that are movably guided in first guide chambers in lateral guide rails and when retrieving the blind with this automatically co-roll, wherein a drive is provided which is coupled to both spring steel strips and acts directly on them, wherein the drive acts on the two spring steel bands in their extended areas and wherein the retractable end of the hanging a drop profile is arranged, which is connected to the two spring steel strips is

Es hat sich gezeigt, dass durch das unmittelbare Einwirken des Antriebs auf die Federstahlbänder, die in der Lage sind, Kräfte in ihrer Längsrichtung zu übertragen, ein zuverlässiges Verstellen des Behangs bei geringem mechanischem Aufwand möglich ist. Entfallen kann bei dieser Lösung die aufwendige Lagerung einer angetriebenen Wickelwelle und es ist auch nicht unbedingt ein Gegenzugsystem notwendig, das man bei Anlagen benötigt, bei welchen das Fallprofil (Spriegel) von einem Elektromotor angetrieben werden soll. Der Antrieb wirkt dabei auf die beiden Federstahlbänder in einem Bereich ein, in dem sie in definierten Lagen geführt und von beiden Seiten her zugänglich sind, wobei sie in ihrer Querrichtung durch die Führungsschiene stabilisiert sind, während die Federstahlbänder in ihrer Längsrichtung selbst eine ausreichende Steifigkeit besitzen, um die Antriebskräfte zu übertragen. Das Fallprofil ist vorzugsweise in den beiden Führungsschienen geführt, wobei es beispielsweise an seinen Enden Gleiter aufweist, die in separaten zweiten Führungskammern der Führungsschienen geführt sind. Bei Außenanlagen, wie z. B. Wintergartenmarkisen, ist die separate Führung des Ausfallprofils sinnvoll, um auftretende Kräfte infolge von Windeinwirkung oder Niederschlag unmittelbar an die Führungsschienen ableiten zu können.It has been shown that by the direct action of the drive on the spring steel bands, which are able to transmit forces in their longitudinal direction, a reliable adjustment of the blind with little mechanical effort is possible. Eliminated in this solution, the complex storage of a driven winding shaft and it is also not necessarily a Gegenzugsystem necessary that you need in systems in which the case profile (bow) to be driven by an electric motor. The drive acts on the two spring steel strips in an area in which they are guided in defined positions and accessible from both sides, being stabilized in their transverse direction by the guide rail, while the spring steel strips themselves have sufficient rigidity in their longitudinal direction to transmit the driving forces. The case profile is preferably guided in the two guide rails, wherein it has for example at its ends slider, which are guided in separate second guide chambers of the guide rails. For outdoor facilities, such. As conservatory awnings, the separate management of the front rail is useful to be able to derive emerging forces due to wind or precipitation directly to the guide rails.

In einer besonders bevorzugten Ausführungsform der Erfindung besitzen die Federstahlbänder einen gewölbten Querschnitt, was als Maßnahme geeignet ist, das selbsttätige Einrollen in besonderer Weise zu fördern.In a particularly preferred embodiment of the invention, the spring steel strips have a curved cross section, which is suitable as a measure to promote the automatic curling in a special way.

Besonders vorteilhaft ist eine Ausführungsform, bei welcher die Krafteinleitung in die beiden Federstahlbänder nahe des aufgewickelten Bereiches erfolgt. Der Antrieb kann dann in das für den Wickelbereich ohnehin vorzusehende Gehäuse integriert werden und die Führungsschienen können entsprechend schlank ausgebildet sein.Particularly advantageous is an embodiment in which the force is introduced into the two spring steel bands near the wound area. The drive can then be integrated into the housing to be provided anyway for the winding area and the guide rails can be designed to be correspondingly slim.

Grundsätzlich ist es möglich, dass die Krafteinleitung in die Federstahlbänder reibschlüssig erfolgt, bevorzugt ist jedoch die formschlüssige Krafteinleitung, weil dort unter allen Umständen ein Schlupf zwischen dem Antrieb und den Federstahlbändern vermieden werden kann, der bei ungleichmäßigem Auftreten in den beiden Federstahlbändern zu einer Schrägstellung des Behangs führen könnte.In principle, it is possible that the introduction of force in the spring steel strips frictionally, but preferably the positive force application, because there is a slip between the drive and the spring steel strips can be avoided under all circumstances, the uneven occurrence in the two spring steel strips to an inclined position of the Could cause hangings.

Eine formschlüssige Mitnahme der Federstahlbänder durch den Antrieb kann beispielsweise mit einer Ausführungsform erreicht werden, bei welcher die Federstahlbänder gelocht sind und der Antrieb auf zwei Nockenscheiben wirkt, die jeweils in die Lochung eines Federstahlbandes eingreifen. Die Lochung der Federstahlbänder verändert deren vorteilhafte Eigenschaften hinsichtlich des selbsttätigen Einrollens nur unwesentlich und erlaubt eine unmittelbare Kraftübertragung von den angetriebenen Nockenscheiben auf die ihnen zugeordneten Federstahlbänder. Um die Sicherheit gegen ein Durchrutschen der Nockenscheibe durch Anheben der Federstahlbänder zu vergrößern, ist vorzugsweise vorgesehen, dass die Führungen der Federstahlbänder im Bereich der Krafteinwirkung enger ausgeführt sind. Dies gilt insbesondere für den eingerasteten Bereich einer Nockenscheibe, wobei im Falle einer reibschlüssigen Mitnahme die Federstahlbänder auch zwischen zwei aneinander gepressten Rollen mit entsprechender Profilierung durchlaufen können. Auch bei Nockenscheiben kann eine mitlaufende Rolle zur Stabilisierung der Lage der Federstahlbänder sinnvoll sein.A positive entrainment of the spring steel strips by the drive can be achieved, for example, with an embodiment in which the spring steel bands are perforated and the drive acts on two cams, which each engage in the perforation of a spring steel strip. The perforation of the spring steel bands changed their advantageous properties in terms of automatic rolling only insignificantly and allows an immediate power transmission from the driven cam discs on their associated spring steel bands. In order to increase the security against slipping of the cam by lifting the spring steel bands, it is preferably provided that the guides of the spring steel strips are made narrower in the field of force. This applies in particular to the engaged area of a cam disc, wherein in the case of a frictional entrainment the spring steel bands can also pass through between two rollers pressed against one another with corresponding profiling. Even with cams a follower role to stabilize the position of the spring steel bands may be useful.

Während bei den hier erörterten Sonnenschutzanlagen grundsätzlich ein Aufwickeln des Behangs auch ohne separate Wickelwelle möglich ist, ist es dennoch bevorzugt, dass der Behang mit den beiden seitlichen Federstahlbändern auf einer lose gelagerten Tuchwelle aufwickelbar ist. Die lose gelagerte Tuchwelle sorgt für eine definierte Lage des aufgewickelten Behangs.While in the shading systems discussed here basically a winding of the curtain is possible even without a separate winding shaft, it is still preferable that the curtain with the two lateral spring steel strips on a loosely mounted cloth shaft can be wound up. The loosely mounted fabric shaft ensures a defined position of the wrapped curtain.

Zudem schafft die Tuchwelle in ihrem Inneren Raum, in welchem in einer weiteren bevorzugten Ausführungsform der Erfindung ein Elektromotor angeordnet ist, der beidseitig Abtriebswellen aufweist. Bei dieser Ausführungsform sind keine außerhalb des Wickelbereiches liegenden Antriebselemente zur Kraftübertragung auf beide Federstahlbänder notwendig, die zwischen den Führungsschienen liegen.In addition, the roller tube creates in its interior space, in which in a further preferred embodiment of the invention, an electric motor is arranged, which has output shafts on both sides. In this embodiment, no lying outside the winding area drive elements for power transmission to both spring steel bands are necessary, which lie between the guide rails.

Da bei Elektromotoren in der Regel eine Anpassung der Drehzahlen notwendig ist, ist es vorteilhaft, wenn die Abtriebswellen jeweils mit Getrieben gekoppelt sind, die beispielsweise aus Zahnradgetrieben bestehen, wobei jeweils ein erstes Zahnrad auf der jeweiligen Abtriebswelle sitzt und jeweils wenigstens ein weiteres Zahnrad vorgesehen ist. Vorzugsweise bilden die Nockenscheiben jeweils ein weiteres Zahnrad des Getriebes, wobei der Vorteil einer solchen Ausbildung darin besteht, dass neben der Nockenscheibe kein weiteres Zahnrad mehr auf einer gleichen Welle vorgesehen sein muss, um die Nockenscheibe an das Untersetzungsgetriebe anzukoppeln. Die Form der Nocken sollte zumindest näherungsweise der Verzahnung entsprechen, um einen zuverlässigen und spielfreien Eingriff zu erreichen. Entsprechend ist die Formgebung der Lochung vorzugsweise dem Nockenquerschnitt und damit dem Zahnquerschnitt der gewählten Verzahnung anzupassen oder anzunähern.Since in electric motors usually an adjustment of the rotational speeds is necessary, it is advantageous if the output shafts are respectively coupled with gears consisting of gear drives, for example, in each case a first gear is seated on the respective output shaft and at least one additional gear is provided , Preferably, the cams each form a further gear of the transmission, the advantage of such a configuration is that in addition to the cam disc no further gear must be provided on a same shaft to couple the cam to the reduction gear. The shape of the cams should at least approximately correspond to the teeth in order to achieve a reliable and play-free engagement. Accordingly, the shape of the perforation is preferably the cam cross section and thus the tooth cross section of the selected teeth to adapt or approximate.

Bei über Gleiter separat an den Führungsschienen geführtem Fallprofil erfolgt die Ankopplung des Fallprofiles an die Federstahlbänder vorzugsweise über Mitnehmer, die in die jeweiligen Lochungen der Federstahlbänder eingreifen.In case of separately guided on the guide rails via slide profile, the coupling of the case profile to the spring steel bands is preferably carried out via drivers which engage in the respective perforations of the spring steel bands.

Zur Verbesserung der Führungseigenschaften hat sich weiterhin eine Maßnahme als vorteilhaft erwiesen, bei welcher in den ersten Führungskammern auf der dem Behang zugewandten Seite jeweils ein Führungskeder angeordnet ist, der die Innenflanke des jeweiligen Federstahlbandes eng umfasst. Der Keder verfügt über gute Gleiteigenschaften und fixiert das ihm zugeordnete Federstahlband dennoch spielfrei.In order to improve the guiding properties, a measure has furthermore proven to be advantageous in which a guide spring is arranged in each case in the first guide chambers on the side facing the blind, which tightly encloses the inner flank of the respective spring steel strip. The piping has good sliding properties and still fixes the spring steel band assigned to it without play.

Die vorbeschriebene Anlage eignet sich zum Einsatz als windstabile Senkrechtmarkise bzw. Fassadenmarkise auch an hohen Gebäuden und kann, wie bereits erwähnt, sowohl bei senkrechter als auch waagerechter Anordnung als Verdunklungsanlage dienen, da kein Stoffspalt zwischen Führungsschiene und dem Tuch verbleibt. Damit können auch großflächige Dachfenster lichtdicht verschlossen werden. Die Vermeidung eines Spaltes ist auch beim Einsatz der Anlage als Insektenschutz von besonderem Vorteil.The above-described system is suitable for use as a wind-stable vertical awning or facade awning on tall buildings and can, as already mentioned, serve both as vertical and horizontal arrangement as a darkening system, since no material gap between the guide rail and the cloth remains. This also large roof windows can be closed light-tight. The avoidance of a gap is also when using the system as insect repellent of particular advantage.

Die Führungsschienen können grundsätzlich auch gebogen sein, beispielsweise um gewölbte Glasflächen zu verschatten oder im Außenbereich Tonnendächer bei ausgefahrenem Behang auszubilden. Bei geneigten Glasflächen können die Anlagen auch in Querrichtung ausfahrbar angeordnet sein.In principle, the guide rails can also be bent, for example to shade curved glass surfaces, or to form bin roofs in the exterior when the curtain is extended. In inclined glass surfaces, the plants can also be arranged extendable in the transverse direction.

Das Antriebsrohr bildet einen Teil des Antriebes 12, wobei auf seinen Enden jeweils ein erstes Zahnrad 20 vorgesehen ist, das mit einem zweiten Zahnrad 22 in Eingriff steht, das an dem weiteren Gehäuseteil 24, das mit dem Seitenteil 16 verbunden ist, gelagert ist. Das zweite Zahnrad 22 steht wiederum mit einem dritten Zahnrad 25 in Eingriff, das auf einer Welle 26 sitzt, auf der auch eine Nockenscheibe 28 angeordnet ist. Die Nockenscheibe 28 steht mit ihren Nocken 30 mit einer Lochung 31 eines Federstahlbandes 32 (siehe auch Fig. 2) in Eingriff, so dass das gezeigte Federstahlband 32 von dem Elektromotor mitnehmbar ist. Auf der gegenüberliegeriden, nicht dargestellten Seite erfolgt die Mitnahme des dort vorgesehenen Federstahlbands in gleicher Weise durch symmetrische Ausbildung des dortigen Seitenteils und eines entsprechenden Antriebes.In Fig. 1 a sunshade system in the form of a conservatory awning 10 is shown in fragmentary form. To release the view of a drive 12, only one side part 16 and a further housing part 24 are shown by a housing 14, wherein the blinds of the sunshade in Fig. 1 has been omitted. A cloth shaft 18 is loosely supported in the housing 14 and formed inside hollow, wherein inside the cloth shaft 18, a drive tube is provided which is driven by an electric motor (not shown). The drive tube extends beyond both ends of the tube shaft 18, wherein the storage of the tube shaft 18 can be carried out on this drive tube. The drive tube forms part of the drive 12, wherein at its ends in each case a first gear 20 is provided, which is in engagement with a second gear 22 which is mounted on the further housing part 24 which is connected to the side part 16. The second Gear 22 is in turn with a third gear 25 into engagement, which sits on a shaft 26 on which a cam plate 28 is arranged. The cam plate 28 is with its cam 30 with a perforation 31 of a spring steel strip 32 (see also Fig. 2 ) so that the shown spring steel strip 32 is entrained by the electric motor. On the gegenüberliegeriden, not shown page, the entrainment of the spring steel strip provided there takes place in the same way by symmetrical design of the local side part and a corresponding drive.

Im Bereich der Mitnahme des Federstahlbandes 32 durch die Nocken 30 der Nockenscheibe 28 ist ein verengter Führungsquerschnitt vorgesehen, der verhindert, dass das Federstahlband von den Nocken 30 abspringen kann. In Ausfahrrichtung schließt sich an den verengten Führungsbereich 34 ein erweiterter Führungsbereich 36 an, der fluchtend in eine erste Führungskammer 38 einer Führungsschiene 40 übergeht. Die Erweiterung 36 des Querschnittes ist notwendig, damit ein Mitnehmer 42, der in die Lochung des Federstahlbandes 32 im Bereich von dessen freiem Ende eingreift, frei in der ersten Führungskammer 38 mit dem Federstahlband 32 beweglich ist. Der Mitnehmer 42 ist mit einem Steckvorsprung 44 (siehe Fig. 2) für ein Fallprofil (nicht gezeigt) einem Gleiter 46 verbunden, der in einer zweiten Führungskammer 48 der Führungsschiene geführt ist. Damit können auf das Fallprofil wirkende Kräfte, die vor allem durch das an diesem befestigte Tuch 50 herrühren, unmittelbar an die Führungsschiene 38 abgeleitet werden.In the area of entrainment of the spring steel strip 32 by the cams 30 of the cam disk 28, a narrowed guide cross-section is provided, which prevents the spring steel strip from jumping off of the cams 30. In the extension direction, an extended guide region 36 adjoins the narrowed guide region 34, which merges into a first guide chamber 38 of a guide rail 40 in alignment. The extension 36 of the cross section is necessary so that a driver 42, which engages in the perforation of the spring steel strip 32 in the region of its free end, is freely movable in the first guide chamber 38 with the spring steel strip 32. The driver 42 is provided with a plug-in projection 44 (see Fig. 2 ) for a drop profile (not shown) connected to a slider 46 which is guided in a second guide chamber 48 of the guide rail. In order for forces acting on the drop profile, which are mainly due to the cloth 50 attached to this, be derived directly to the guide rail 38.

Das Tuch (nicht gezeigt) selbst ist über seine gesamte Länge mit dem Federstahlband 32 gefügt, wobei die Fügestelle nur über einen Teilbereich der Oberseite des gewölbt geformten Federstahlbandes 32 reicht oder dieses teilweise umschließt, so dass die Innenkante 52 des Federstahlbandes 32 entfernt von dem Tuch 50 liegt. Gut zu erkennen ist in Fig. 2 auch die erste Führungskammer 38 der Führungsschiene 40 für das Federstahlband 32 mit dem erweiterten Bereich 36. Das Federstahlband 32 ist zur Verbesserung der Führung in einem Führungskeder 54 geführt, der formschlüssig in einer hinterschnittenen Nut 56 angeordnet ist und die Innenkante 52 des Federstahlbandes 32 eng umfasst.The blanket (not shown) itself is joined over its entire length to the spring steel strip 32, the joint extending over or partially enclosing only a portion of the top of the domed spring steel strip 32 so that the inner edge 52 of the spring steel strip 32 is removed from the blanket 50 lies. Good to see in Fig. 2 Also, the first guide chamber 38 of the guide rail 40 for the spring steel strip 32 with the extended portion 36. The spring steel strip 32 is guided to improve the leadership in a Leitungskeder 54 which is positively arranged in an undercut groove 56 and the inner edge 52 of the spring steel strip 32 includes tight ,

Bedingt durch seine Wölbung hat das hier gezeigte Federstahlband 32 die Neigung, sich zusammenzurollen, sobald es die Führungskammer 38 bzw. den verengten Führungsbereich 34 verläßt. Beim Einholen des Behangs 50 sorgen die beidseitig angeordneten Federstahlbänder 50 dafür, dass sich der Behang 50 selbsttätig um die Tuchwelle 18 aufwickelt, was durch den aufgewickelten Bereich 58 in Fig. 1 veranschaulicht ist. Die Enden der Federstahlbänder 50 können, müssen aber nicht an der Tuchwelle 18 festgelegt sein.Due to its curvature, the spring steel strip 32 shown here has the tendency to curl up as soon as it leaves the guide chamber 38 or the narrowed guide region 34. When retrieving the curtain 50, the spring steel strips 50 arranged on both sides ensure that the curtain 50 automatically winds around the fabric shaft 18, which is reflected by the wound-up region 58 in FIG Fig. 1 is illustrated. The ends of the spring steel bands 50 may, but need not be fixed to the fabric shaft 18.

Wie aus Fig. 1 gut ersichtlich ist, benötigen die zum Antreiben der Federstahlbänder 32 vorgesehenen Zahnradgetriebe nur einen sehr geringen Bauraum, wobei der Elektromotor selbst auch innerhalb des Antriebsrohres angeordnet sein kann. Die Führungsschienen 40 selbst können in ihren Querschnitten an die Führungskammern 38, 48 angepaßt sein, wobei insbesondere der bei Wintergartenmarkisen übliche Bauraum für ein Gegenzugsystem zum Antreiben des Fallprofils 44 entfallen kann.How out Fig. 1 can be clearly seen, need for driving the spring steel strips 32 provided gear transmission only a very small space, the electric motor itself can also be arranged within the drive tube. The guide rails 40 themselves may be adapted in their cross-sections to the guide chambers 38, 48, wherein in particular the usual in conservatory awning space for a counter pull system for driving the case profile 44 may be omitted.

Beim Ausfahren des Behangs 50 aus der in Fig. 1 skizzierten eingefahrenen Stellung, treibt der Elektromotor zunächst die Nockenscheibe 38 im Gegenuhrzeigersinn im Sinne der Darstellung gemäß Fig. 1 an, wobei die nicht gezeigte gegenüberliegende Seite spiegelbildlich ausgebildet ist und ebenfalls angetrieben wird. Die Nocken 30 greifen in die Lochung der Federstahlbänder 32 ein und wickeln diese dadurch vom Wickelvorrat 58 ab. Bedingt durch den engen Führungsquerschnitt der ersten Führungskammer 38, sind die Federstahlbänder 32 gegen Knicken gesichert und dadurch in der Lage, die auftretenden Reibungskräfte beim Ausfahren des Behangs in Druckrichtung zu überwinden. Das Fallprofil 44 kann dadurch in eine der Behanglänge entsprechende Endstellung gefahren werden. Beim Einholen des Behangs wird die Nockenscheibe 28 in gegenläufiger Richtung angetrieben, wodurch die Federstahlbänder 32 zurück in das Gehäuse 14 geschoben werden. Die Federstahlbänder 32 rollen sich in dem Gehäuse 14 selbsttätig ein, wodurch auch der Behang 50, der zwischen den beiden Federstahlbändern 32 angeordnet ist, mit auf der Tuchwelle 18 aufgewickelt wird.When extending the blind 50 from the in Fig. 1 sketched retracted position, the electric motor initially drives the cam 38 in the counterclockwise direction in the sense of illustration Fig. 1 at, wherein the opposite side is not shown in mirror image and is also driven. The cams 30 engage in the perforation of the spring steel strips 32 and thereby wrap them off from the winding stock 58. Due to the narrow guide cross section of the first guide chamber 38, the spring steel strips 32 are secured against kinking and thereby able to overcome the frictional forces occurring during the extension of the curtain in the printing direction. The case profile 44 can thereby be moved into an end position corresponding to the hanging length. When retrieving the curtain, the cam plate 28 is driven in the opposite direction, whereby the spring steel strips 32 are pushed back into the housing 14. The spring steel bands 32 automatically roll in the housing 14, whereby the curtain 50, which is arranged between the two spring steel strips 32, is wound on the fabric shaft 18.
