Description

Gegenstand der Erfindung ist eine Verbindung mindestens eines Bandes eines Behangs mit einer Welle, ein Halteteil dieser Verbindung und ein Verfahren zum Verbinden mindestens eines Bandes eines Behangs mit einer Welle gemäss den Merkmalen der Patentansprüche 1, 7 und 8.The invention relates to a connection of at least one band of a curtain with a shaft, a holding part of this compound and a method for connecting at least one band of a blind with a shaft according to the features of claims 1, 7 and 8.

Roll- und Rafflamellenstoren sowie Rollläden umfassen jeweils einen Behang mit Lamellen bzw. Stäben, die an Haltebändern wie z.B. textilen Zug- und/oder Tragbändern befestigt sein können. Es ist bekannt, solche Bänder z.B. mittels schraubbarer Briden bzw. Klemmen oder durch Kleben jeweils direkt an einer Aufzugswelle zu befestigen. Die Montage des Behangs erfolgt herkömmlich an einer am Bau vorinstallierten Aufzugswelle, fortan auch kurz Welle genannt. Dies ist relativ umständlich und aufwändig, da die Welle in der Regel in einer oben an einer Gebäudeaussparung ausgebildeten Sturznische mit eingeschränkter Zugänglichkeit angeordnet ist, und da jedes Band einzeln derart an der Welle befestigt werden muss, dass der Behang bezüglich der Gebäudeaussparung bzw. seitlich an der Gebäudeaussparung angeordneter Führungsprofile ausgerichtet ist. Herkömmlich können an der Welle sehnenartig durchgehende Öffnungen ausgenommen sein, durch welche die Bänder hindurchgeschlauft und an der Welle befestigt werden.Roll and Rafflamellenstoren and shutters each include a curtain with slats or rods that can be attached to straps such as textile pull and / or straps. It is known to fasten such bands, for example, by means of screwable clips or clamps or by gluing each directly to an elevator shaft. The assembly of the curtain is traditionally on a preinstalled at construction elevator shaft, henceforth also called short wave. This is relatively cumbersome and complex, since the shaft is usually arranged in a trained above a building recess cambered niche with limited accessibility, and since each band must be individually secured to the shaft so that the curtain with respect to the building recess or laterally the Gebäedeaussparung arranged guide profiles is aligned. Conventionally can be excluded on the shaft chord-like through openings through which the belts are passed through and secured to the shaft.

Aus der DE-U1-20319507 ist eine Feder zum Befestigen und Sichern eines Rollladens an einer rechteckigen Aussparung einer achteckigen Aufzugswelle bekannt. Die Feder umfasst ein Band mit einer Ausstanzung und zwei hakenartig umgeformten federnden Zungen im Bereich des oberen Bandendes. Die Zungen werden in die Aussparung an der Welle eingedrückt. Am unteren Ende der Feder ist der Rollladen befestigt.From the DE-U1-20319507 a spring is known for securing and securing a shutter to a rectangular recess of an octagonal elevator shaft. The spring comprises a band with a punched out and two hook-like formed resilient tongues in the region of the upper band end. The tongues are pressed into the recess on the shaft. At the lower end of the spring, the shutter is attached.

Die DE-U1-29504742 offenbart einen Rollladenpanzer, an dessen Oberkante bandartige Einhängefedern aus einem leicht biegbaren Material hervorragen. Die Endbereiche dieser Bänder sind als trapezförmige Kopfteile mit nutartigen Hinterschneidungen ausgebildet. Zum Befestigen der Einhängefedern werden die Laschen am Ende des Kopfteils umgebogen und in einen Längsschlitz an der Aufzugswelle eingeschoben, wo sie wieder in ihre ursprüngliche Lage zurückfedern und Anschläge bilden, welche die Einhängefedern an der Welle halten.The DE-U1-29504742 discloses a roller shutter, at the upper edge of which tape-like suspension springs protrude from a material which is easily bendable. The end portions of these bands are designed as trapezoidal head parts with groove-like undercuts. To attach the suspension springs, the tabs are bent at the end of the head part and inserted into a longitudinal slot on the elevator shaft, where they spring back into their original position and form stops that hold the suspension springs on the shaft.

In der DE-U1-202006007416 wird ein Verbindungselement zum wieder lösbaren Verbinden eines Markisentuchs an einer Wickelwelle beschrieben. Das Verbindungselement umfasst eine Rastvorrichtung mit zwei federnden Schenkeln, die mit einer in Längsrichtung der Wickelwelle ausgebildeten Nut rastend verbindbar sind. Das Markisentuch ist am Verbindungselement angenäht und/oder festgeklebt.In the DE-U1-202006007416 a connecting element for releasably connecting an awning fabric to a winding shaft is described. The connecting element comprises a latching device with two resilient legs, which are latchably connectable with a groove formed in the longitudinal direction of the winding shaft. The awning fabric is sewn to the connecting element and / or glued.

Die DE-U1-29603976 offenbart eine Vorrichtung zum Befestigen eines Rollladenbehangs an einem Aufrollrohr mit quer zu dessen Drehachse eingelassenen Öffnungen. In diese Öffnungen werden Hilfsvorrichtungen eingehakt, die wiederum zum Einhaken von Bändern in Gestalt von Stahllamellen ausgebildet sind, wobei diese Stahllamellen einen durch Kerben begrenzten Kopf umfassen. Sowohl zur Befestigung der Hilfsvorrichtung am Aufrollrohr als auch zur Befestigung des Bandes an der Hilfsvorrichtung werden federnde Rastelemente benutzt, nämlich die U-förmig gebogenen Haken der Hilfsvorrichtung und der Endbereich des Bandes mit der Engstelle im Bereich der Kerben.The DE-U1-29603976 discloses a device for attaching a roller blind hanging on a roll-up tube with inserted transversely to the axis of rotation openings. In these openings auxiliary devices are hooked, which in turn are designed for hooking bands in the form of steel plates, said steel plates comprise a limited by notches head. Both for fastening the auxiliary device on the roll-up tube as well as for fastening the tape to the auxiliary device resilient locking elements are used, namely the U-shaped hooks of the auxiliary device and the end portion of the belt with the bottleneck in the region of the notches.

Es ist Aufgabe der vorliegenden Erfindung, eine kostengünstige, einfache und lösbare Verbindungvon Bändern eines Behangs mit einer Aufzugswelle sowie ein Halteteil einer solchen Verbindung zu schaffen. Diese Aufgabe wird gelöst durch eine Verbindung, ein Halteteil und durch ein Verfahren zum Verbinden mindestens eines Bandes eines Behangs mit einer Welle gemäss den Merkmalen der Patentansprüche 1 und 7 und 8.It is an object of the present invention to provide a cost-effective, simple and releasable connection of bands of hangings with an elevator shaft and a holding part of such a connection. This object is achieved by a connection, a holding part and by a method for connecting at least one band of a blind to a shaft according to the features of patent claims 1 and 7 and 8.

Die Verbindung umfasst je eine an den abgelängten, über die obersten Stäbe oder Lamellen des Behangs hinausragenden oberen Enden der Bänder befestigte Haltevorrichtung, insbesondere eine Spange mit einer aus der Bandfläche schräg hervorragenden federnden Zunge.The connection comprises in each case a holding device fastened to the cut-to-length, upper ends of the bands projecting beyond the uppermost bars or slats of the curtain, in particular a clip with a spring tongue projecting obliquely out of the strip surface.

Diese Spangen werden in je eine an der Welle ausgebildete Ausnehmung eingeschoben. Die Gestalt und die Abmessungen dieser Ausnehmung sind so bemessen, dass die Zunge der Spange beim Einschieben in die Ausnehmung durch Anlage an der ihr zugewandten Seite der Ausnehmung federnd zurückgebogen wird. An dieser Seitenwand ist ein kleiner Absatz ausgebildet. Sobald die Zunge über diesen Absatz hinausgeschoben wird, federt sie nach aussen und wird dann aufgrund der wirkenden Federkraft wieder leicht gegen die Seitenwand der Ausnehmung gedrückt. Nach dem Prinzip eines Widerhakens wird jetzt das Herausziehen des Bandes aus der Ausnehmung verhindert. Zum Lösen des Bandes wird die Spange innerhalb der Ausnehmung durch Hochstossen des Bandes oder z.B. mit einem Schraubendreher weiter in die Ausnehmung hinein gestossen. Mit einem spachtelartigen Werkzeug kann die Federzunge hintergriffen und das Einhaken der Zunge am Absatz beim anschliessenden herausziehen der Spange aus der Ausnehmung verhindert werden. Die Montage und Demontage des Behangs ist somit mühelos und ohne Justierarbeiten möglich. Insbesondere muss die Aufzugswelle nur von der Seite mit den Einschuböffnungen für die Bänder her zugänglich sein. Anhand einiger Figuren wird die Erfindung im Folgenden am Beispiel eines Lamellenstores näher beschrieben. Dabei zeigen

These clips are inserted into each one formed on the shaft recess. The shape and dimensions of this recess are dimensioned so that the tongue of the clip is resiliently bent back upon insertion into the recess by abutment against the side facing the recess. On this side wall a small paragraph is formed. As soon as the tongue is pushed over this shoulder, it springs outwards and is then pressed against the sidewall of the recess again due to the acting spring force. According to the principle of a barb now the withdrawal of the tape is prevented from the recess. To release the tape, the clip is pushed within the recess by pushing up the tape or eg with a screwdriver into the recess into it. With a spatula-like tool, the spring tongue can be engaged behind and the hooking of the tongue on the paragraph during the subsequent pulling out of the clip can be prevented from the recess. The assembly and disassembly of the curtain is thus easily and without adjustments possible. In particular, the elevator shaft must be accessible only from the side with the insertion openings for the bands ago. Based on some figures, the invention will be described in more detail below using the example of a slat blind. Show

Figur 1 zeigt einen Teil einer Aufzugsvorrichtung für einen Behang (nicht dargestellt) bei einem Store. In der Regel umfasst ein solcher Store eine oben in einer Gebäudeaussparung parallel zu Lamellen oder Stäben des Behangs ausgerichtete Aufzugswelle, fortan kurz Welle 1 genannt. Je nach Ausbildung des Behangs sind ein oder mehrere orthogonal zu den Stäben oder Lamellen ausgerichtete Bänder 3 mit der Welle 1 oder einer koaxial mit der Welle 1 verbundenen Spule 5 derart verbunden, dass sie am Mantel der um eine Aufzugsachse f drehbar gelagerten Welle 1 oder Spule 5 auf- und abgewickelt werden können. Da sich die Art der Bandbefestigung an der Spule 5 nicht von jener an der Welle 1 unterscheidet, wird im Folgenden stellvertretend nur die Befestigung an der Welle 1 beschrieben. Ein- oder beidseitig eines oder mehrerer der genannten Bänder 3 können flanschartige Bandführungen 7 ausgebildet sein. Die Bänder 3 können nebst der Verbindung mit der Welle 1 je nach Art des Behangs z.B. nur mit einer Unterschiene oder mit mehreren oder allen Lamellen oder Stäben des Behangs verbunden sein (nicht dargestellt). Bei einem Behang mit mehreren Bändern 3 können diese gleiche oder unterschiedliche Funktionen haben und z.B. als Aufzugsbänder, Tragbänder oder Wendebänder eingesetzt werden. Bei Rollladen und Roll-Lamellenstoren können auch die Stäbe bzw. Lamellen an der Welle 1 auf- und abgerollt werden. FIG. 1 shows a part of a lift device for a curtain (not shown) at a store. As a rule, such a store comprises an elevator shaft which is aligned at the top in a building recess parallel to lamellae or bars of the hanging, henceforth called wave 1 for short. Depending on the design of the blind, one or more bands 3 oriented orthogonally to the bars or lamellae are connected to the shaft 1 or to a coil 5 connected coaxially to the shaft 1 in such a way that it rotates on the mantle of the shaft 1 rotatably mounted about an elevator shaft f or coil 5 can be wound up and unwound. Since the type of tape attachment to the spool 5 does not differ from that on the shaft 1, only the attachment to the shaft 1 will be described below by way of representation. One or both sides of one or more of the mentioned bands 3 can be flange-like Tape guides 7 may be formed. The bands 3, in addition to the connection with the shaft 1 depending on the type of hanging eg only with a lower rail or with several or all lamellae or rods of the blind be connected (not shown). In a curtain with multiple bands 3, these can have the same or different functions and are used, for example, as elevator belts, straps or turning tapes. With roller shutters and rolling lamella blinds, the bars or lamellae on the shaft 1 can also be rolled up and unrolled.

Figur 2 zeigt einen Querschnitt der Aufzugsvorrichtung aus Figur 1 entlang der Linie A-A. An der Welle 1 ist von der im Wesentlichen zylindrischen Mantelfläche her eine Ausnehmung 9 mit einer Eingangsöffnung 11 ausgebildet. Die Ausnehmung 9 hat vorzugsweise mindestens abschnittweise einen rechteckigen Querschnitt mit einer Breite s1. Die Ausnehmung 9 kann z.B. bezüglich der Welle 1 radial oder - wie dargestellt - sehnenartig angeordnet sein. Sie kann sackartig oder - wie dargestellt - tunnelartig bzw. durchgehend ausgebildet sein. FIG. 2 shows a cross section of the elevator device FIG. 1 along the line AA. On the shaft 1, a recess 9 with an inlet opening 11 is formed from the substantially cylindrical jacket surface. The recess 9 preferably has at least sections a rectangular cross-section with a width s1. The recess 9, for example, with respect to the shaft 1 radially or - as shown - be arranged like a chord. It can be baggy or - as shown - tunnel-like or continuous.

An den oberen Enden der mit der Welle 1 zu verbindenden Bänder 3 ist eine Haltevorrichtung ausgebildet, die ein federndes Rast- oder Schnappelement umfasst. Figur 3 zeigt eine solche aus einem Blech, insbesondere einem Federstahlblech gefertigte Haltevorrichtung in Gestalt einer Spange 13 mit einem sprungbrettartig ausgebildeten, mit der angrenzenden Oberfläche der Spange 13 einen spitzen Winkel α einschliessenden Zunge 15. Figur 4 zeigt eine Abwicklung der Spange 13 aus Figur 3. Sie umfasst einen ersten Schenkel 17 mit einem ersten Abschnitt 17a und einem zweiten Abschnitt 17b sowie orthogonal dazu einen zweiten Schenkel 19 mit einem Anfangsabschnitt 19a, einem mittleren Abschnitt 19b und einem Endabschnitt 19c. Der rechteckige erste Abschnitt 17a des ersten Schenkels 17 ist identisch mit dem Anfangsabschnitt 19a des zweiten Schenkels 19 und wird auch als Verbindungszone 21 bezeichnet.At the upper ends of the to be connected to the shaft 1 bands 3, a holding device is formed, which comprises a resilient latching or snap element. FIG. 3 shows such a made of a metal sheet, in particular a spring steel sheet holding device in the form of a clasp 13 with a springboard-like, with the adjacent surface of the clasp 13 a acute angle α including tongue 15. FIG. 4 shows a settlement of the clasp 13 FIG. 3 , It comprises a first leg 17 having a first portion 17a and a second portion 17b and orthogonal thereto a second leg 19 having a start portion 19a, a middle portion 19b and an end portion 19c. The rectangular first portion 17 a of the first leg 17 is identical to the initial portion 19 a of the second leg 19 and is also referred to as the connection zone 21.

Der zweite Schenkel 19 ist zweifach je U-förmig nach innen umgeformt, derart, dass der Anfangsabschnitt 19a, der mittlere Abschnitt 19b und der Endabschnitt 19c stapelartig und parallel zueinander angeordnet sind, wobei der Endabschnitt 19c zwischen dem Anfangsabschnitt 19a bzw. der Verbindungszone 21 und dem mittleren Abschnitt 19b angeordnet ist.The second leg 19 is U-shaped twice in each case, such that the starting portion 19 a, the middle portion 19 b and the end portion 19 c are stacked and arranged parallel to each other, wherein the end portion 19 c between the initial portion 19 a and the connecting zone 21 and the middle portion 19 b is arranged.

Das Ende des Bandes 3 ist derart zwischen benachbarten Abschnitten 19a, 19b, 19c des zweiten Schenkels 19 der Spange 13 geklemmt und um einen oder mehrere dieser Abschnitte 19a, 19b, 19c gewickelt, dass das Band 3 kraftschlüssig mit der Spange 13 verbunden ist. Das Band 3 ragt zwischen der Verbindungszone 21 der beiden Schenkel 17, 19 und dem Endabschnitt 19c des zweiten Schenkels 19 auf Seite des Endes der Zunge 15 aus der Spange 13 hervor. Zusätzlich können Mittel zum formschlüssigen Verbinden des Bandes 3 mit der Spange 13 vorgesehen sein, z.B. an der Spange 13 vorstehende, gestanzte Zacken (nicht dargestellt). Die Spange 13 kann auch in anderer Weise ausgebildet sein und z.B. in der Abwicklung eine oder mehrere weitere Laschen umfassen, die beispielsweise zum Vereinfachen des Loslösens der Spange 13 aus der Ausnehmung 9 genutzt werden können (nicht dargestellt). Im Bereich der Öffnung 11 ist ein in die Ausnehmung 9 vorspringender Absatz 23 ausgebildet. Beim Einschieben der Haltevorrichtung wird die seitlich vorstehende Zunge 15 durch den Absatz 23 leicht in Richtung der angrenzenden Verbindungszone 21 gedrückt und federt wieder nach aussen, sobald das freie Ende der Zunge 15 den Absatz 23 überwunden hat. Da die Breite des Bandendes mit der angeschlossenen Spange 13 im unbelasteten Zustand etwas grösser ist als die Breite s1 der Ausnehmung 11, wird die Zunge 15 durch die wirkende Federkraft über den Absatz 23 gedrückt, sodass ein Herausziehen des Bandes 3 nicht bzw. nur mit Hilfe eines Werkzeugs möglich ist.The end of the band 3 is clamped between adjacent portions 19a, 19b, 19c of the second leg 19 of the clasp 13 and wound around one or more of these portions 19a, 19b, 19c such that the band 3 is non-positively connected to the clasp 13. The band 3 projects between the connection zone 21 of the two legs 17, 19 and the end portion 19c of the second leg 19 on the side of the end of the tongue 15 from the clasp 13. In addition, means may be provided for the positive connection of the band 3 with the clasp 13, for example on the Clasp 13 protruding, punched prongs (not shown). The clasp 13 may also be formed in another way and include, for example, in the settlement one or more other tabs that can be used for example to simplify the detachment of the clip 13 from the recess 9 (not shown). In the region of the opening 11, a recess 23 protruding into the recess 9 is formed. When inserting the holding device, the laterally projecting tongue 15 is pressed by the shoulder 23 slightly in the direction of the adjacent connection zone 21 and springs back out again as soon as the free end of the tongue 15 has overcome the paragraph 23. Since the width of the tape end with the connected clip 13 in the unloaded state is slightly larger than the width s1 of the recess 11, the tongue 15 is pressed by the acting spring force on the shoulder 23 so that a withdrawal of the tape 3 is not or only with the help a tool is possible.
