  • Such connections between the fabric strip and the winding shaft are safe and relatively easy to handle.
  • a further disadvantage is that the fabric, for example an acrylic awning fabric, which can be 1 to 3 mm thick, is led radially out of the recess on the winding shaft and as a result, after the first wrap and further wraps during winding, the area of the awning that lies above the slot in the recess is slightly lifted and consequently this area is visible on the awning due to this bulge when it is extended. This leads to a negative appearance of the awning.

  • the area of the rod outside the groove pivots away from the groove again, holding the rod firmly within the recess.
  • a hole is drilled into the rod along its long edge, which is connected to the surface of the rod by a slot. The piping on an awning must be laboriously pushed axially into this hole and thus held to the rod.
  • This arrangement allows a recessed arrangement of a rod holding the awning, but

  • An awning equipped in this way can only be inserted axially into the winding shaft. This means that in order to replace the awning, e.g. if it is damaged or when fitting a new sun protection system, the winding shaft has to be lifted out of its bearing, then the awning, e.g. a 6 m wide awning, has to be inserted and then the heavy winding shaft together with the unwound awning has to be moved up into the bearings for the shaft.
  • Such an arrangement is very time-consuming during assembly (axial insertion and lifting of the heavy shaft with the awning on it and its subsequent installation on the top of a window or door opening).
  • An object of the present invention is to provide a connecting element for fastening or connecting the edge of a textile web to a winding shaft. create a system that, on the one hand, enables simple assembly, i.e., simple connection of the web of material to the winding shaft at its place of use, and also ensures a seamless transition from the winding shaft to the awning.

Description

Verbindungselement zum Verbinden einer Warenbahn mit einer Wickelwelle Gegenstand der Erfindung ist ein Verbindungselement zum Verbinden einer Warenbahn mit einer Wickelwelle gemäss Oberbegriff des Patentanspruch 1.Connecting element for connecting a web of material to a winding shaft. The subject matter of the invention is a connecting element for connecting a web of material to a winding shaft according to the preamble of patent claim 1.

Markisen als Sonnen- und/oder Regenschutz umfassen eine Stoffbahn, die auf einer Wickelwelle aufwickelbar ist, um sie geschützt und auf kleinem Raum bei Nichtgebrauch stauen zu können. Üblicherweise wird in die mit der Wickelwelle zu verbindende Kante des Stoffs in einem Hohlsaum ein Stab eingelegt und dadurch ein Kederwulst gebildet. Alternativ kann auch eine Kederfahne an der Kante des Stoffs angebracht, z.B. aufgenäht werden. Zur Befestigung der Kante des Stoffs mit dem Kederwulst an der Wickelwelle ist an letzterer unter der Manteloberfläche eine axial verlaufende Ausnehmung als Kederschiene angebracht, in welche der Keder eingelegt werden kann. Meistens ist die Ausnehmung im Querschnitt etwa kreisrund und die Ausnehmung steht nur an einer schmalen Stelle mit der Oberfläche der Wickelwelle in Verbindung, so dass nach Einschieben der Stoffbahn mit dem Keder in axialer Richtung die Stoffbahn gehalten wird. Solche Verbindungen zwischen Stoffbahn und Wickelwelle sind sicher und verhältnismässig einfach zu handhaben.Awnings as sun and/or rain protection comprise a fabric strip that can be wound up on a winding shaft so that it can be protected and stored in a small space when not in use. Usually, a rod is inserted into a hemstitch in the edge of the fabric that is to be connected to the winding shaft, thereby forming a piping bead. Alternatively, a piping flag can be attached to the edge of the fabric, e.g. sewn on. To attach the edge of the fabric with the piping bead to the winding shaft, an axially running recess is attached to the latter under the casing surface as a piping rail, into which the piping can be inserted. The recess is usually approximately circular in cross-section and the recess is only connected to the surface of the winding shaft at a narrow point, so that after the fabric strip is pushed in, the fabric strip is held in the axial direction by the piping. Such connections between the fabric strip and the winding shaft are safe and relatively easy to handle.

Nachteilig an einer solchen Verbindung ist der Aufwand zum Einführen des Keders, da dieser nur stirnseitig in die Wickelwelle eingeführt werden kann und folglich die Wickelwelle an deren Ende für das Einführen freigelegt werden muss. Ein weiterer Nachteil besteht darin, dass die Stoffbahn, beispielsweise ein Markisenstoff aus Acryl, der immerhin eine Dicke von 1 bis 3 mm aufweisen kann, radial aus der Ausnehmung an der Wickelwelle herausgeführt wird und dadurch nach der ersten Umschlingung und weiteren Umschlingungen beim Aufwickeln der Bereich der Markise, die über dem Schlitz der Ausnehmung liegt, leicht abgehoben wird und folglich dieser Bereich sich durch diesen Wulst auf der Markise, wenn sie ausgefahren ist, abzeichnet. Dies führt zu einem negativen Erscheinungsbild der Markise.The disadvantage of such a connection is the effort required to insert the piping, as it can only be inserted into the winding shaft from the front and the winding shaft must therefore be exposed at the end for insertion. A further disadvantage is that the fabric, for example an acrylic awning fabric, which can be 1 to 3 mm thick, is led radially out of the recess on the winding shaft and as a result, after the first wrap and further wraps during winding, the area of the awning that lies above the slot in the recess is slightly lifted and consequently this area is visible on the awning due to this bulge when it is extended. This leads to a negative appearance of the awning.

Wird die Markise bzw. deren Kante auf die Welle aufgeschraubt oder aufgenietet und durch einen Abdeckstab auf die Oberfläche der Welle gedrückt, so entsteht dasselbe negative Erscheinungsbild, da sich auch dieser Bereich auf der Markise ein- oder mehrmals abzeichnet.If the awning or its edge is screwed or riveted onto the shaft and pressed onto the surface of the shaft by a cover rod, the same negative appearance occurs, as this area also shows through on the awning once or several times.

Aus der EP 3 431 678 A1 ist weiter eine Anordnung zum Verbinden einer Warenbahn, insbesondere Markise, mit einer Wickelwelle bekannt. In dieser Anordnung ist in der Wickelwelle eine Ausnehmung eingelassen, deren Basis kreisbogenabschnittförmig ausgebildet ist und an deren beiden Seitenkanten im Querschnitt S-förmig verlaufende Bereiche ausgebildet sind, sodass der Schlitz in der Manteloberfläche der Wickelwelle eine geringere Breite aufweist wie die Basis der Ausnehmung. Die Ausnehmung bildet für einen einklickbaren Stab durch eine im Wesentlichen im Querschnitt T-förmige Nut Raum, sodass dieser nicht über die Manteloberfläche der Wickelwelle hinausragt, jedoch mit seinen seitlichen Kanten die überstehenden Randbereiche des Schlitzes untergreifen kann. Um den Stab, an welchem die Markise befestigt wird, in die axial verlaufende Ausnehmung einsetzen zu können, ist an der Unterseite des Stabs eine Nut eingelassen, damit der ausserhalb der Nut liegende Bereich des Stabs, der aus einem verhältnismässig weichen biegsamen Kunststoffmaterial hergestellt sein muss, beim Auflegen und gleichzeitigen Zusammenpressen des Stabs auf seiner gesamten Länge auf die Ausnehmung bzw. den Schlitz zurückweisen kann und so die Breite des Stabs kurzfristig verkürzt wird. Nach dem radialen Einschieben des Stabs schwenkt der Stabbereich ausserhalb der Nut wieder von der Nut weg und hält so den Stab innerhalb der Ausnehmung fest. Weiter ist im Stab eine entlang dessen Längskanten verlaufende Bohrung eingelassen, die durch einen Schlitz mit der Oberfläche des Stabs verbunden ist. In diese Bohrung muss der Keder an einer Markise mühsam axial eingeschoben und so am Stab gehalten werden.From the EP 3 431 678 A1 Furthermore, an arrangement for connecting a web of material, in particular an awning, to a winding shaft is known. In this arrangement, a recess is set into the winding shaft, the base of which is designed as a circular arc section and on both side edges of which there are S-shaped Areas are formed so that the slot in the casing surface of the winding shaft is less wide than the base of the recess. The recess creates space for a click-in rod through a groove that is essentially T-shaped in cross-section, so that the rod does not protrude beyond the casing surface of the winding shaft, but can reach under the protruding edge areas of the slot with its side edges. In order to be able to insert the rod to which the awning is attached into the axially running recess, a groove is let into the underside of the rod so that the area of the rod outside the groove, which must be made of a relatively soft, flexible plastic material, can point back towards the recess or slot over its entire length when the rod is placed on top and simultaneously pressed together, thus shortening the width of the rod for a short time. After the rod has been pushed in radially, the area of the rod outside the groove pivots away from the groove again, holding the rod firmly within the recess. Furthermore, a hole is drilled into the rod along its long edge, which is connected to the surface of the rod by a slot. The piping on an awning must be laboriously pushed axially into this hole and thus held to the rod.

Diese Anordnung ermöglicht zwar eine versenkte Anordnung eines die Markise festhaltenden Stabs, jedoch ist einerseits das Verbinden der Markise mit dem Stab aufwendig, da diese über die gesamte Länge des Stabs in diesen eingeschoben werden muss. Dies kann bei Markisen von mehreren Metern Länge rein platzmässig und auch arbeitsmässig viel Aufwand benötigen. Im Weiteren kann andererseits der Stab, nachdem er in die Ausnehmung in der Wickelwelle eingeklipst ist, darin nicht sicher gehalten werden, denn, falls eine erhöhte Zugkraft auf die Markise einwirkt, vor allem wenn die Ausnehmung an der Wickelwelle nicht im oberen Scheitel derselben, sondern weiter unten zu liegen kommt, erfolgt ein Durchbiegen des Stabs und dadurch kann der elastische Haltebereich aus der Ausnehmung herausgezogen werden, da dieser bekanntlich für das Einführen schwenkbeweglich am Stab ausgebildet sein muss. Einerseits ist folglich die Verbindung zwischen Markise und Stab sehr aufwendig und andererseits ist die Verankerung des Stabs nach der Montage an der Wickelwelle nicht in jeder Position gewährleistet.This arrangement allows a recessed arrangement of a rod holding the awning, but On the one hand, connecting the awning to the rod is complex because it has to be pushed into the rod along its entire length. For awnings that are several meters long, this can take up a lot of space and work. On the other hand, once the rod has been clipped into the recess in the winding shaft, it cannot be held securely in place because if there is increased pulling force on the awning, particularly if the recess on the winding shaft is further down rather than at the top, the rod will bend and the elastic holding area can be pulled out of the recess because, as we know, this has to be designed to be pivotable on the rod for insertion. On the one hand, the connection between the awning and the rod is therefore very complex, and on the other hand, the anchoring of the rod on the winding shaft is not guaranteed in every position after it has been mounted.

Aus DE 10 2018 103 796 A1 und US 5 384 941 sind weitere Lösungen mit in Ausnehmungen einpressbaren elastischen Haltebereichen bekannt.Out of EN 10 2018 103 796 A1 and US$ 5,384,941 Other solutions with elastic holding areas that can be pressed into recesses are known.

Weiter ist aus der CH 698 032 eine Wickelwelle bekannt, bei welcher entlang der Kante der Markise, welche mit der Wickelwelle verbunden werden muss, ein S-förmiger Haltebereich befestigt. Dieser greift in eine kreisrunde, durch einen Schlitz mit der Oberfläche verbundene Bohrung in der Wickelwelle ein. Ein sicherer Halt der Markise ist nur gewährleistet, wenn die Markise bereits einmal um die Wickelwelle herumgewickelt ist und über dem S-förmigen Haken zu liegen kommt und diesen radial auf die Wickelwelle presst. Ein sicherer Halt ist damit nicht gewährleistet.Furthermore, the CH 698 032 A winding shaft is known, in which an S-shaped holding area is attached along the edge of the awning, which has to be connected to the winding shaft. This engages in a circular hole in the winding shaft, which is connected to the surface by a slot. A secure hold of the awning is only guaranteed if the awning has already been wound around the winding shaft once and is above the S-shaped hook and presses it radially onto the winding shaft. This does not guarantee a secure hold.

Weiter ist aus der US 2006/0207731 eine Verbindungsanordnung zwischen einer Wickelwelle und der Kante einer Markise bekannt. An der Kante der Markise isst ein Halteelement befestigt, dessen Ende T-förmig ausgebildet ist und in eine entsprechende T-förmige Nut in der Wickelwelle eingreift. Eine solcherart ausgerüstete Markise kann nur axial in die Wickelwelle eingeführt werden. Dies bewirkt, dass für einen Wechsel der Markise, z.B. wenn diese beschädigt ist oder auch bei der Montage einer neuen Sonnenschutzanlage, die Wickelwelle aus deren Lagerung herausgehoben, dann die Markise, z.B. eine 6 m breite Markise, eingeführt werden muss und nachher die schwere Wickelwelle samt der nicht aufgewickelten Markise nach oben in die Lager für die Welle befördert werden muss. Eine solche Anordnung ist sehr zeitaufwendig während der Montage (axiales Einführen und Anheben der schweren Welle mit darauf befindlicher Markise und deren nachträgliche Montage an der Oberseite einer Fenster- oder Türöffnung).Furthermore, the US2006/0207731 a connecting arrangement between a winding shaft and the edge of an awning is known. A holding element is attached to the edge of the awning, the end of which is T-shaped and engages in a corresponding T-shaped groove in the winding shaft. An awning equipped in this way can only be inserted axially into the winding shaft. This means that in order to replace the awning, e.g. if it is damaged or when fitting a new sun protection system, the winding shaft has to be lifted out of its bearing, then the awning, e.g. a 6 m wide awning, has to be inserted and then the heavy winding shaft together with the unwound awning has to be moved up into the bearings for the shaft. Such an arrangement is very time-consuming during assembly (axial insertion and lifting of the heavy shaft with the awning on it and its subsequent installation on the top of a window or door opening).

Eine Aufgabe der vorliegenden Erfindung besteht nun darin, ein Verbindungselement zur Befestigung bzw. zur Verbindung der Kante einer textilen Warenbahn mit einer Wickelwelle zu schaffen, das einerseits eine einfache Montage, d.h. ein einfaches Verbinden der Warenbahn mit der Wickelwelle an deren Einsatzort ermöglicht, als auch einen stufenlosen Übergang von der Wickelwelle in die Markise gewährleistet.An object of the present invention is to provide a connecting element for fastening or connecting the edge of a textile web to a winding shaft. create a system that, on the one hand, enables simple assembly, i.e., simple connection of the web of material to the winding shaft at its place of use, and also ensures a seamless transition from the winding shaft to the awning.

Gelöst wird diese Aufgabe durch ein Verbindungselement gemäss den Merkmalen des Patentanspruchs 1. Das erfindungsgemässe Verbindungssystem ermöglicht es, den Verbindungsbereich der Warenbahn vollständig unter der Manteloberfläche der Wickelwelle anzuordnen, so dass kein stufenartiger Übergang an der Oberfläche der Wickelwelle erfolgt und nach der ersten Umschlingung der Wickelwelle durch die Warenbahn der über dem Verbindungsbereich zu liegen kommende Bereich der zweiten Wickellage der Warenbahn nicht radial nach aussen gedrängt wird, sondern innerhalb dem bogenförmigen Verlauf der Manteloberfläche der Wickelwelle zu liegen kommt. Der Übergang, der von der ersten Umschlingung in die zweite erfolgt, ist folglich stufenlos ohne Bildung eines Wulstes. Erreicht wird dies durch einen Einhänge-Profilstab, der einseitig mit dem Kantenbereich der Warenbahn verbunden wird und der vollständig in eine Ausnehmung unter der Oberfläche der Wickelwelle einlegbar und dort einrastbar befestigt wird. Sehr vorteilhaft und zeitsparend wirkt sich das System aus, indem der Einhänge-Profilstab mit der Stoffbahn radial an die in einem Tür- oder Fenstersturz eingebaute Wickelwelle herangeführt und in einer Ausnehmung in deren Mantelfläche werkzeugfrei eingehängt und eingerastet werden kann. Ein axiales Verschieben während des Gebrauchs entfällt, da der Einhänge-Profilstab in der Ausnehmung einrastet. Eine Demontage der Wickelwelle zur Einführung des Verbindungselements ist daher nicht mehr notwendig. Der Einhänge-Profilstab kann in einfacher und kostengünstiger Weise direkt mit dem Kantenbereich der Warenbahn verbunden werden, indem die Verbindung durch eine Ultraschallschweissung oder durch Kleben erfolgt. Zudem muss an der Kante der Warenbahn kein Saum angebracht werden, sondern die geschnittene Kante kann ohne weitere Nachbehandlung am Einhänge-Profilstab befestigt werden. Alternativ kann in einer vorteilhaften Ausgestaltung an der Kante der Warenbahn vorab ein Übergangselement befestigt werden, welches seinerseits mit dem Einhänge-Profilstab verbunden wird. Das Übergangselement verbessert den sanften Einlauf der Warenbahn von der Ausnehmung in die Mantelfläche der Wickelwelle.This object is achieved by a connecting element according to the features of patent claim 1. The connecting system according to the invention makes it possible to arrange the connecting area of the material web completely under the surface of the winding shaft, so that there is no step-like transition on the surface of the winding shaft and after the first wrap around the winding shaft by the material web, the area of the second winding layer of the material web that comes to lie above the connecting area is not pushed radially outwards, but comes to lie within the curved course of the surface of the winding shaft. The transition that takes place from the first wrap to the second is therefore stepless without the formation of a bead. This is achieved by a hanging profile bar that is connected on one side to the edge area of the material web and that can be inserted completely into a recess under the surface of the winding shaft and fastened there so that it can be snapped in. The system is very advantageous and time-saving because the hanging profile bar with the material web is radially attached to the winding shaft and can be hung and locked into a recess in its outer surface without tools. Axial displacement during use is not necessary because the hanging profile bar locks into the recess. Dismantling the winding shaft to insert the connecting element is therefore no longer necessary. The hanging profile bar can be connected directly to the edge area of the web in a simple and cost-effective manner by making the connection using ultrasonic welding or gluing. In addition, no seam needs to be attached to the edge of the web; instead, the cut edge can be attached to the hanging profile bar without any further post-treatment. Alternatively, in an advantageous embodiment, a transition element can be attached to the edge of the web in advance, which in turn is connected to the hanging profile bar. The transition element improves the smooth entry of the web from the recess into the outer surface of the winding shaft.

An der Wickelwelle lässt sich die Ausnehmung sehr einfach herstellen. Die Ausnehmung weist einen im Verhältnis zu deren Tiefe sehr breiten Schlitz auf, der das Einführen des Einhänge-Profilstabs in radialer Richtung ermöglicht und nicht wie bisher eine Demontage der Wickelwelle verlangt, um axial eingeführt zu werden.The recess can be made very easily on the winding shaft. The recess has a slot that is very wide in relation to its depth, which allows the hanging profile bar to be inserted in a radial direction and does not require the winding shaft to be dismantled in order to be inserted axially, as was previously the case.

Der bisher an der Warenbahn notwendigerweise auszubildende Saum mit einem darin angeordneten Stab zur Bildung eines Kederwulstes als Befestigungselement an der Wickelwelle entfällt. Der Einhänge-Profilstab kann mit geringem Arbeitsaufwand durch Kleben oder eine Ultraschallschweissung an der geschnittenen ungesäuberten Warenbahnkante direkt befestigt werden. In der bevorzugten Ausgestaltung des Systems wird die ungesäuberte Warenbahnvorderkante mit einem Anschlussband durch Schweissen oder Kleben verbunden. Das Anschlussband seinerseits wird ebenfalls durch Verkleben oder Verschweissen mit dem Einhänge-Profilstab verbunden. Dies ermöglicht es, dass der Einhänge-Profilstab vollständig in der schlitzförmigen Ausnehmung eingesetzt werden kann und keine Teile über die Manteloberfläche der Wickelwelle hinausragen. Wird zusätzlich ein Anschlussband zwischen die Warenbahn und dem Einhänge-Profilstab eingesetzt, so kann eine völlig übergangsfreie Verbindung zwischen der Wickelwelle und der Warenbahn erreicht werden. Der Einhänge-Profilstab und das Anschlussband, welches bevorzugt aus einem weicheren Material besteht als der Profilstab, können auch einteilig hergestellt sein, wodurch nur eine Verbindung zur Stoffkante erfolgen muss. Muss eine Warenbahn einer Markise nach Jahren infolge Defekts ausgewechselt werden, so lässt sich die Warenbahn mit dem daran befestigten Einhänge-Profilstab ohne Demontage der Wickelwelle aus der Ausnehmung herausschieben und durch eine neue oder reparierte Warenbahn ersetzen.The seam that had to be formed on the fabric web with a rod arranged in it to form a The piping bead as a fastening element on the winding shaft is no longer required. The hanging profile bar can be attached directly to the cut, uncleaned edge of the material web with little effort by gluing or ultrasonic welding. In the preferred design of the system, the uncleaned front edge of the material web is connected to a connecting tape by welding or gluing. The connecting tape is in turn also connected to the hanging profile bar by gluing or welding. This allows the hanging profile bar to be inserted completely into the slot-shaped recess and no parts protrude beyond the surface of the winding shaft. If a connecting tape is also inserted between the material web and the hanging profile bar, a completely seamless connection between the winding shaft and the material web can be achieved. The hanging profile bar and the connecting tape, which are preferably made of a softer material than the profile bar, can also be made as one piece, meaning that only one connection to the edge of the material needs to be made. If a fabric strip of an awning needs to be replaced after years due to a defect, the fabric strip can be pushed out of the recess with the attached hanging profile rod without dismantling the winding shaft and replaced with a new or repaired fabric strip.

In Figur 1 ist mit Bezugszeichen 1 ein System zur Verbindung einer Warenbahn 3, z.B. der Stoff für eine Markise, mit einer Wickelwelle 5 bezeichnet. Die manuell oder elektrisch antreibbare Wickelwelle 5 weist einen kreisrunden Querschnitt mit einer Manteloberfläche 7 auf.In Figure 1 Reference number 1 designates a system for connecting a web of material 3, e.g. the material for an awning, to a winding shaft 5. The manually or electrically driven winding shaft 5 has a circular cross-section with a jacket surface 7.

Die Wickelwelle 5 wird vorzugsweise als Aluminiumprofil hergestellt. Im Scheitel der Wickelwelle 5 in Figur 2 ist eine unter der Manteloberfläche 7 ausgebildete Ausnehmung 9 ersichtlich, über der ein axial verlaufender Schlitz 11 (Fig. 6) mit einer Breite b in der Manteloberfläche 7 ausgebildet ist. Die Breite b des Schlitzes 11 kann in Umfangsrichtung eine Ausdehnung bis zum Mass des Radius r der Wickelwelle 1 aufweisen. Selbstverständlich kann - in Abhängigkeit des Durchmessers der Wickelwelle 5 - auch eine wesentlich kleinere Öffnungsbreite b gewählt werden.The winding shaft 5 is preferably made of aluminum profile. At the top of the winding shaft 5 in Figure 2 a recess 9 is visible under the casing surface 7, above which an axially extending slot 11 ( Fig.6 ) with a width b in the casing surface 7. The width b of the slot 11 can have an extension in the circumferential direction up to the dimension of the radius r of the winding shaft 1. Of course - depending on the diameter of the winding shaft 5 - a much smaller opening width b can also be selected.

Die Ausnehmung 9 hat im Querschnitt die Gestalt einer T-Nut oder, wie in den Figuren dargestellt, eines auf dem Rücken liegenden, flachgedrückten C's, dessen Rücken 13 leicht radial konvex nach aussen gebogen verlaufen kann,The recess 9 has in cross-section the shape of a T-slot or, as shown in the figures, a flattened C lying on its back, the back 13 of which can be slightly radially convexly curved outwards,

also in etwa parallel zum fehlenden Bereich in der Manteloberfläche 7 über dem Schlitz 11. Die Ausnehmung 9 weist eine innere Breite B auf. Die beiden Übergänge von der Manteloberfläche 7 in den Rücken 13 verlaufen in etwa in der Gestalt von gegeneinander gerichteten Halbkreisen (vergl. Fig. 1,2,6).i.e. approximately parallel to the missing area in the jacket surface 7 above the slot 11. The recess 9 has an inner width B. The two transitions from the jacket surface 7 into the back 13 run approximately in the shape of semicircles directed towards each other (cf. Fig. 1,2 , 6 ).

Die Ausnehmung 9 dient im System zur Aufnahme eines Einhänge-Profilstabs 17. Im Querschnitt weist der Einhänge-Profilstab 17 die Gestalt eines auf dem Kopf stehenden T's mit einer Bodenfläche 19 auf, deren konvexe Krümmung dem Rücken 13 in der Ausnehmung 9 an der Wickelwelle 5 entsprechen kann. Eine der Bodenfläche 19 gegenüberliegende Kontaktfläche 21 am Körper des Einhänge-Profilstabs 17 dient zur Aufnahme und Verbindung eines Anschlussbandes 23 oder direkt dem Kantenbereich der Warenbahn 3. Das Anschlussband 23 als Teil des Profilstabs 17 dient dazu, den vorderen Kantenbereich der Warenbahn 3 mit dem Einhänge-Profilstab 17 unlösbar zu verbinden. Das Anschlussband 23 weist in Figur 4 auf der rechten Seite an seiner radial aussenliegenden Oberfläche einen Absatz 25 auf, so dass die Oberfläche eine im dünneren Bereich 23' auf dem Anschlussband 23 befestigte Warenbahn 3 stufenlos oder absatzlos in die äussere Oberfläche 27 des Anschlussbandes 23 übergeht. Das Anschlussband 23 und eine darauf befestigte vordere Kante einer Warenbahn 3 liegen folglich in einer gemeinsamen konvex gebogenen Fläche.The recess 9 serves in the system to accommodate a suspension profile bar 17. In cross section, the Hanging profile bar 17 has the shape of an upside down T with a bottom surface 19, the convex curvature of which can correspond to the back 13 in the recess 9 on the winding shaft 5. A contact surface 21 on the body of the hanging profile bar 17 opposite the bottom surface 19 serves to receive and connect a connecting strip 23 or directly to the edge area of the web 3. The connecting strip 23 as part of the profile bar 17 serves to permanently connect the front edge area of the web 3 to the hanging profile bar 17. The connecting strip 23 has in Figure 4 on the right-hand side on its radially outer surface a step 25, so that the surface of a material web 3 fastened in the thinner region 23' on the connecting belt 23 merges smoothly or without a step into the outer surface 27 of the connecting belt 23. The connecting belt 23 and a front edge of a material web 3 fastened thereto therefore lie in a common convexly curved surface.

Das Anschlussband 23 kann an seinem linken freien Ende in Figur 4 eine grössere Wandstärke aufweisen als im anschliessenden, im Kontakt mit dem Einhänge-Profilstab 17 liegenden Abschnitt. Die Verbindung zwischen dem Einhänge-Profilstab 17 und dem Anschlussband 23 kann durch eine Verklebung oder, wie im Beispiel dargestellt, durch eine Ultraschallschweissung erfolgen, durch welche im Schweissbereich 29 eine unbedeutende Einbuchtung im Anschlussband 23 entstehen kann und allenfalls auch in der Kontaktfläche 21 des Einhänge-Profilstabs 17.The connecting band 23 can be inserted at its left free end into Figure 4 have a greater wall thickness than in the adjacent section in contact with the suspension profile bar 17. The connection between the suspension profile bar 17 and the connecting strip 23 can be made by gluing or, as shown in the example, by ultrasonic welding, which creates an insignificant indentation in the welding area 29. connecting strip 23 and possibly also in the contact surface 21 of the suspension profile bar 17.

Der Einhänge-Profilstab 17 ist an dessen beiden Enden stufenförmig ausgebildet, so dass die obere Kontaktfläche 21 kürzer ist als die untere Bodenfläche 19.The suspension profile bar 17 is stepped at both ends so that the upper contact surface 21 is shorter than the lower base surface 19.

Der erste stufenförmige Abschnitt 31 des Einhänge-Profilstabs 17 nimmt auf der linken Seite das dickere Ende des Anschlussbandes 23 auf und ist länger als der zweite stufenförmige Abschnitt 33 auf der rechten Seite in den Figuren 3 und 5.The first step-shaped section 31 of the suspension profile bar 17 receives the thicker end of the connecting strip 23 on the left side and is longer than the second step-shaped section 33 on the right side in the Figures 3 and 5 .

Die Dicke c1 des Einhänge-Profilstabs 17 im Anschluss an den ersten stufenförmigen Abschnitts 31 ist kleiner als die Dicke c2 vor dem zweiten stufenförmigen Abschnitt 33. Durch diese Massnahme gelangt die Oberfläche 27 des Anschlussbandes 23 stufenlos in die Manteloberfläche 7 der Wickelwelle 5.The thickness c 1 of the suspension profile bar 17 following the first step-shaped section 31 is smaller than the thickness c 2 before the second step-shaped section 33. This measure allows the surface 27 of the connecting strip 23 to pass seamlessly into the casing surface 7 of the winding shaft 5.

Um eine optimale dauerhafte Verbindung zwischen dem Einhänge-Profilstab 17 und dem Anschlussband 23 an der Kontaktfläche 21 zu erlangen, sind diese aus einem ultraschallschweissbaren Material bestehend oder aus Materialien, die optimal und dauerhaft miteinander verklebbar sind. Das Anschlussband 23 ist vorzugsweise aus einem Kunststoff hergestellt, der biegsamer, weicher und zusammenpressbarer ist als das härtere und damit steife Material des Einhänge-Profilstabs 17. Der Einhänge-Profilstab 17 und das Anschlussband 23 können auch einteilig hergestellt sein, z.B. durch einen Extrudiervorgang oder einen Zweikomponenten-Spritzvorgang, so dass eine spätere Verklebung oder Verschweissung der beiden Elemente miteinander nicht mehr notwendig ist.In order to achieve an optimal permanent connection between the hanging profile bar 17 and the connecting band 23 at the contact surface 21, these are made of an ultrasonically weldable material or of materials that can be optimally and permanently bonded together. The connecting band 23 is preferably made of a plastic that is more flexible, softer and more compressible than the harder and therefore stiffer material of the hanging profile bar 17. The hanging profile bar 17 and the connecting band 23 can also be made in one piece, e.g. by means of a Extrusion process or a two-component injection molding process, so that subsequent gluing or welding of the two elements together is no longer necessary.

Nachfolgend wird die Funktionsweise der Verbindung zwischen der Wickelwelle 5 und dem Einhänge-Profilstab 17 mit dem daran befestigten Anschlussband 23 und der an diesem befestigten Warenbahn 3 der ersten Ausführungsform beschrieben. Nach dem Zuschneiden/Konfektionieren einer Warenbahn 3 für eine Markise wird deren vordere Kante bzw. der vordere Kantenbereich an dem Absatz 25 am Anschlussband 23 anstossend mit diesem verbunden. Die Verbindung kann durch eine Verklebung erfolgen oder durch eine Ultraschallschweissung, welche die beiden Materialien, nämlich die Warenbahn 3 und das Anschlussband 23, unlösbar miteinander verbindet. Die auf diese Weise vorbereitete Warenbahn 3 mit daran befestigtem Anschlussband 23 wird nun mit dem Einhänge-Profilstab 17 verbunden. Diese Verbindung kann ebenfalls durch eine Verklebung oder eine Ultraschallschweissung erfolgen. Selbstverständlich könnte auch zuerst der Einhänge-Profilstab 17 mit dem Anschlussband 23 verbunden werden und erst anschliessend die Warenbahn 3 an das Anschlussband 23 befestigt werden.The following describes how the connection between the winding shaft 5 and the hanging profile bar 17 with the connecting tape 23 attached to it and the material web 3 attached to it in the first embodiment works. After cutting/assembling a material web 3 for an awning, its front edge or the front edge area is connected to the shoulder 25 on the connecting tape 23 so that it abuts against it. The connection can be made by gluing or by ultrasonic welding, which permanently connects the two materials, namely the material web 3 and the connecting tape 23. The material web 3 prepared in this way with the connecting tape 23 attached to it is now connected to the hanging profile bar 17. This connection can also be made by gluing or ultrasonic welding. Of course, the hanging profile bar 17 could also be connected to the connecting tape 23 first and only then the material web 3 attached to the connecting tape 23.

Die so vorbereitete Markise kann nun an der Wickelwelle 5, die im Sturz einer Fenster- oder Türöffnung oder in einem Wetterschutzgehäuse drehbar gelagert und durch einen hand- oder motorischen Antrieb drehbar ist, montiert werden. Dazu ist es nicht nötig die Wickelwelle 5 von deren Aufhängung und Antrieb zu lösen, sondern es wird der Einhänge-Profilstab 17 mit seinem vorne, d.h. auf der linken Seite in den Figuren, liegenden stufenförmigen Absatz 31 im Wesentlichen in spitzem Winkel zur Manteloberfläche in Richtung des Pfeils F in die Ausnehmung 9 eingeführt. Dabei untergreift der erste stufenförmige Abschnitt 31 den halbkreisförmigen Bereich 15 der Ausnehmung 9. Beim Einführen kann das verdickte Ende des Anschlussbandes 23, da es vorzugsweise aus einem weicheren Material als der zentrale Bereich des Profilstabs 17 besteht, etwas zurückgedrängt bzw. zurückgeschoben werden. Sobald der erste stufenförmige Abschnitt 31 unter die halbkreisförmige Kante der Ausnehmung 9 eingeschoben und untergeschoben ist, wird der Einhänge-Profilstab 17 in Richtung des Pfeiles P (Uhrzeigersinn) geschwenkt und gelangt danach mit seiner Bodenfläche 19 in Kontakt mit dem Rücken 13 der Ausnehmung 9 (vergl. Figur 1).The awning prepared in this way can now be attached to the winding shaft 5, which is rotatably mounted in the lintel of a window or door opening or in a weatherproof housing and can be manually or motor drive. To do this, it is not necessary to detach the winding shaft 5 from its suspension and drive, but the suspension profile bar 17 is inserted into the recess 9 with its stepped shoulder 31 at the front, i.e. on the left-hand side in the figures, essentially at an acute angle to the casing surface in the direction of arrow F. The first stepped section 31 engages under the semicircular area 15 of the recess 9. When inserting, the thickened end of the connecting band 23 can be pushed back or pushed back slightly, since it is preferably made of a softer material than the central area of the profile bar 17. As soon as the first step-shaped section 31 is inserted and pushed under the semicircular edge of the recess 9, the suspension profile bar 17 is pivoted in the direction of the arrow P (clockwise) and then comes with its bottom surface 19 into contact with the back 13 of the recess 9 (cf. Figure 1 ).

Sobald die Wickelwelle 5 im Gegenuhrzeigersinn in Drehung versetzt wird, wird einerseits die Warenbahn 3 radial an die Manteloberfläche 7 der Wickelwelle 5 angedrückt und der Einhänge-Profilstab 17 bzw. dessen zweiter stufenförmiger Abschnitt 33 in den kreisbogenförmigen Randbereich der Ausnehmung 9 hineingezogen. Der erste stufenförmige Abschnitt 31 verbleibt weiterhin radial gehalten im bogenförmigen Abschnitt der Ausnehmung 9 (linke Seite). Unterstützt wird das Einschieben im Uhrzeigersinn zusätzlich durch die Spannkraft des zusammengepressten weichen Endes des Anschlussbandes 23. Der Einhänge-Profilstab 17 liegt nun, die Ausnehmung 9 annähernd ausfüllend, an beiden Kanten gehalten in der Ausnehmung 9. Die Oberfläche 27 des Anschlussbandes 23 und die aussenliegende Oberfläche der Warenbahn 3 liegen in einer übergangslos verlaufenden im Wesentlichen kreisrunden Bahn in der Manteloberfläche 7 der Wickelwelle 5.As soon as the winding shaft 5 is rotated in an anti-clockwise direction, the web 3 is pressed radially against the surface 7 of the winding shaft 5 and the hanging profile bar 17 or its second step-shaped section 33 is drawn into the circular edge area of the recess 9. The first step-shaped section 31 remains radially held in the curved section of the recess 9 (left side). The clockwise insertion is additionally supported by the tensioning force of the compressed soft end of the connecting band 23. The suspension profile bar 17 now lies, almost filling the recess 9, held at both edges in the recess 9. The surface 27 of the connecting band 23 and the outer surface of the web of material 3 lie in a seamless, essentially circular path in the casing surface 7 of the winding shaft 5.

In einer weiteren Ausgestaltung der Erfindung gemäss den Figuren 7 bis 9 ist der Einhänge-Profilstab 17' als Einheit mit dem Anschlussband 23" ausgebildet und damit einstückig aus zwei Komponenten unterschiedlicher Härte herstellbar und als Verbindungselement 35 bezeichnet. Das Verbindungselement 35 umfasst einen ersten stufenförmigen Abschnitt 31 und einen zweiten stufenförmigen Abschnitt 33. Im Weiteren ist auf dem ersten stufenförmigen Abschnitt 31 eine federnde Nase 37 angeformt sowie auf der gegenüberliegenden Seite über dem zweiten stufenförmigen Abschnitt 33 ein ebenfalls aus einem weicheren Material als der zentrale Teil des Verbindungselements 35 erzeugter Anschlussbandabschnitt 23'. Der Grundkörper des Verbindungselements 35 ist vorzugsweise aus einem Kunststoffmaterial mit grösserer Stärke und vor allem hoher Steifigkeit hergestellt als die Nase 37 und der Abschnitt 23' des Anschlussbands 23. Hergestellt wird das Verbindungselement im Spritzgiessverfahren mit zwei unterschiedlichen Kunststoffkomponenten. Die beiden Komponenten, nämlich die biegesteife für den Grundkörper und die elastisch verformbare für die Nase 37, und fakultativ auch für den Abschnitt 23', sind folglich untrennbar verbunden.In a further embodiment of the invention according to the Figures 7 to 9 the suspension profile bar 17' is designed as a unit with the connecting band 23" and can thus be manufactured in one piece from two components of different hardness and is referred to as a connecting element 35. The connecting element 35 comprises a first step-shaped section 31 and a second step-shaped section 33. Furthermore, a resilient nose 37 is formed on the first step-shaped section 31 and on the opposite side above the second step-shaped section 33 there is a connecting band section 23' also made of a softer material than the central part of the connecting element 35. The base body of the connecting element 35 is preferably made of a plastic material with greater strength and above all higher rigidity than the nose 37 and the section 23' of the connecting band 23. The connecting element is manufactured using an injection molding process with two different plastic components. The two components, namely the rigid one for the base body and the elastically deformable one for the nose 37, and optionally also for the section 23', are therefore inseparably connected.

Die Verbindung der Warenbahn 3 mit dem eine geringere Stärke bzw. Dicke und vorzugsweise hoher Elastizität aufweisenden Abschnitt des Anschlussbands 23' ausserhalb des Absatzes 25, dient als Verbindungsbereich des Verbindungselements 35 mit der Warenbahn 3. Die Verbindung erfolgt entweder durch Kleben mit einem Kleber, durch gegenseitige Verklebung durch Wärmeeinwirkung oder durch eine Ultraschallschweissung.The connection of the web 3 with the section of the connecting tape 23' outside the shoulder 25, which has a lower strength or thickness and preferably high elasticity, serves as the connection area of the connecting element 35 with the web 3. The connection is made either by gluing with an adhesive, by mutual bonding by heat or by ultrasonic welding.

Nachfolgend wird die Funktionsweise der Verbindung zwischen der Wickelwelle 5 und dem Einhänge-Profilstab 17 mit der daran befestigten Warenbahn 3 der zweiten Ausführungsform beschrieben.The functionality of the connection between the winding shaft 5 and the suspension profile bar 17 with the web of material 3 of the second embodiment attached thereto is described below.

Nach dem Zuschneiden/Konfektionieren der Warenbahn 3 wird deren vordere Kante am Absatz 25 des Anschlussbereichs 23' angelegt und durch einen Kleber, eine thermische Verschmelzung oder durch eine Ultraschallschweissung mit dem Anschlussbereich 23' verbunden. Das Verbinden der Warenbahn 3 mit dem Verbindungselement 35 kann vorzugsweise bereits in den Räumlichkeiten des Herstellers der Markise oder am Einsatzort kurz vor der Befestigung der Warenbahn 3 an der Wickelwelle 5 erfolgen.After cutting/assembling the web 3, its front edge is placed on the shoulder 25 of the connection area 23' and connected to the connection area 23' by an adhesive, thermal fusion or ultrasonic welding. The connection of the web 3 with the connecting element 35 can preferably already in the premises of the awning manufacturer or at the place of use shortly before the fabric web 3 is attached to the winding shaft 5.

Die am Verbindungselement 35 befestigte Warenbahn 3 wird dann, wie in Figur 2 des ersten Ausführungsbeispiels dargestellt, vor Ort, d.h. an der bereits an einem Gebäude befestigten Wickelwelle eingeklinkt. Dabei führt der Monteur den ersten stufenförmigen Abschnitt 31 am Einhänge-Profilstab (17) in spitzem Winkel zur Oberfläche des Mantels der Wickelwelle 5 unter die halbkreisförmige Ausnehmung 15 in der Ausnehmung 9 an der Wickelwelle 5 ein. Nun berührt die elastische Nase 37, die sich als Rippe über die gesamte Länge des Verbindungselements 15 oder über mindestens mehrere Teillängen erstreckt in Anlage mit dem Mantel 7 der Wickelwelle 5. Durch einen leichten Druck in Richtung der Kraft F in Figur 2 schiebt er den ersten stufenförmigen Abschnitt 31 vollständig in die halbkreisförmige Ausnehmung, bis der zweite stufenförmige Abschnitt 33 durch Verschwenken des Einhänge-Profilstabs 17 im Uhrzeigersinn in Anlage mit dem Rücken 13 der Ausnehmung 9 gelangt. Sobald die Kraft F auf den Einhänge-Profilstab 17 aufgehoben wird, verschiebt sich das Verbindungselement 35 im Uhrzeigersinn durch die Kraft der elastisch gespannten Nase 37 und gelangt mit seinem zweiten stufenförmigen Abschnitt 33 unter den halbkreisförmigen Bereich der Ausnehmung 9 auf der rechten Seite. Damit ist der Einhänge-Profilstab 17 in der Ausnehmung 9 verankert. Sobald die Wickelwelle 5 im Gegenuhrzeigersinn in Drehung versetzt wird, um die Warenbahn 3 aufwickeln zu können, wird das Verbindungselement 35 zusätzlich bis zum Anschlag in der Ausnehmung 9 verschoben, sofern nicht bereits die Kraft der Nase 37 das Verbindungselement 35 vollständig im Uhrzeigersinn verschoben hat.The web 3 attached to the connecting element 35 is then, as in Figure 2 of the first embodiment, on site, ie on the winding shaft already attached to a building. The fitter introduces the first step-shaped section 31 on the suspension profile bar (17) at an acute angle to the surface of the casing of the winding shaft 5 under the semicircular recess 15 in the recess 9 on the winding shaft 5. Now the elastic nose 37, which extends as a rib over the entire length of the connecting element 15 or over at least several partial lengths, comes into contact with the casing 7 of the winding shaft 5. By applying slight pressure in the direction of the force F in Figure 2 it pushes the first step-shaped section 31 completely into the semicircular recess until the second step-shaped section 33 comes into contact with the back 13 of the recess 9 by pivoting the suspension profile bar 17 clockwise. As soon as the force F on the suspension profile bar 17 is removed, the connecting element 35 moves clockwise due to the force of the elastically tensioned nose 37 and reaches with its second step-shaped section 33 under the semicircular area of the recess 9 on the right side. The suspension profile bar 17 is thus in the Recess 9 is anchored. As soon as the winding shaft 5 is rotated in an anti-clockwise direction in order to be able to wind up the web of material 3, the connecting element 35 is additionally displaced as far as it will go in the recess 9, unless the force of the nose 37 has already displaced the connecting element 35 completely in a clockwise direction.

Muss im Schadensfall eine Markise bzw. die Warenbahn 3 ausgetauscht werden, so lässt sich diese in umgekehrter Reihenfolge ohne Demontage der Wickelwelle 5 von dieser abnehmen.If an awning or the fabric web 3 has to be replaced in the event of damage, it can be removed in the reverse order without dismantling the winding shaft 5.
