Abstract

The pull-up device of a pull-up curtain consists of a winding shaft, disposed parallel to the longitudinal axis of the curtain rod, driven in rotary motion and rotatably mounted in bearing blocks mounted on the curtain rod, several mutually spaced winding spools being fixed to the winding shaft. A vertical pull-up band each can be wound on every winding spool, said pull-up band being led through mutually vertically spaced band guidance elements of a loop band which is fastened to the curtain in vertical alignment with the winding spool, the lower end of the pull-up element being fastened to the lower part of the curtain. The pull-up band is of rectangular section, and the winding spool is axially movable on the winding shaft, the flanges of the winding spool being only slightly further apart than corresponds to the width of the pull-up band.

Description

Die Erfindung betrifft einen Raff-Vorhang nach dem Oberbegriff des Patentanspruchs 1.The invention relates to a roman blind according to the preamble of claim 1.

Ein eingangs genannter Raff-Vorhanq ist beispielsweise mit dem Gegenstand des DE-GM 82 00 021 bekannt geworden. Dort ist an einer Aluminium-Profilschiene, die mittels Trägern an der Wand oder an der Decke befestigt ist, mit Hilfe von Lagerböcken aus Kunststoff, die am Profil der Aluminiumschiene eingehängt sind, eine Wickelwelle drehbar gelagert.An initially mentioned Raff-Vorhanq has become known, for example, with the subject of DE-GM 82 00 021. There is on an aluminum rail, which is fixed by means of supports on the wall or on the ceiling, supported by means of bearing blocks made of plastic, which are suspended on the profile of luminiumschiene A a winding shaft rotatably.

Auf der Wickelwelle sind drehfest mehrere Wickelspulen angeordnet, die relativ breit ausgebildet sind. An einer Seite der Wickelwelle ist drehfest eine Antriebsscheibe angebracht, über die eine glatte Schnur läuft. Die Schnur ist zu einer Endlosschlaufe zusammengeführt und greift klemmend zwischen die Flansche der Antriebsscheibe ein, so daß bei Zug an der Schnur die Antriebsscheibe entsprechend gedreht wird und damit die Wickelwelle mit den darauf angeordneten Wickelspulen drehend angetrieben ist.A plurality of winding coils are arranged on the winding shaft in a rotationally fixed manner and are of relatively wide construction. A drive pulley is attached to one side of the winding shaft so that it rotates, over which a smooth cord runs. The cord is brought together to form an endless loop and engages in a clamped manner between the flanges of the drive pulley, so that when the cord is pulled, the drive pulley is rotated accordingly and the winding shaft with the winding coils arranged thereon is driven in rotation.

Senkrecht unter den jeweiligen Wickelspulen ist der Vorhang mit vertikalen Schlaufenbändern vernäht, die sich über die gesamte vertikale Länge des Vorhanges erstrecken. Je nach gefordertem Raffabstand des Vorhanges sind in fest vorgegebenen und gleichmässigen Abständen Schlaufen am Schlaufenband befestigt. Durch die Schlaufen ist ein vertikales Zugelement geführt, das bei dieser bekannten Anordnung als Schnur ausgebildet ist. Das Zugelement ist mit seiner einen Seite zwischen den Flanschen der Wickelspule befestigt und jeweils einer Wickelspule ist ein solches Zugelement zugeordnet. Aufgrund der Tatsache, daß der Flanschabstand der Wickelspulen wesentlich größer ist als die Schnurbreite, besteht der wesentliche Nachteil, daß beim Aufwickeln der Schnur durch die Wickelspulen diese relativ ungeordnet auf die Wickelspule aufgewickelt wird. Die Schnurwindungen kommen hierbei kreuz und quer übereinander zu liegen, so daß hinsichtlich mehrerer, nebeneinanderliegender Wickelspulen die eine Wickelspule die ihr zugeordnete Schnur stärker verkürzt, als die andere, benachbarte Wickelspule. Der Vorhang ist dann während des Raff-Vorganges auf der einen Seite stärker hochgezogen, als auf der anderen Seite, so daß er im hochgezogenen Zustand schiefhängt, durchhängt oder Falten wirft.The curtain is sewn vertically under the respective winding spools with vertical loop bands which extend over the entire vertical length of the curtain. Depending on the required gathering distance of the curtain, loops are attached to the loop band at fixed, uniform intervals. A vertical traction element is guided through the loops and is designed as a cord in this known arrangement. The tension element is attached with one side between the flanges of the winding spool and such a tension element is assigned to each winding spool. Due to the fact that the flange spacing of the winding spools is significantly larger than the cord width, there is the major disadvantage that when the cord is wound up by the winding spools, it is wound onto the winding spool in a relatively disordered manner. The line turns come to lie criss-cross one above the other, so that with regard to several winding spools lying next to one another, the one winding spool shortens the cord associated with it more than the other, adjacent winding spool. The curtain is then pulled up more strongly on one side than on the other side during the gathering process, so that when it is pulled up it hangs, sags or wrinkles.

Weiterer Nachteil ist, daß die schnurförmigen Zugelemente im Bereich der Schlaufen des Schlaufenbandes eine relativ große Reibung erfuhren, so daß die Raffung des Vorhanges relativ schwergängig ging und der Faltenwurf unbefriedigend war.Another disadvantage is that the cord-shaped tension elements in the loops of the loop band experienced a relatively large amount of friction, so that the gathering of the curtain was relatively difficult and the drapery was unsatisfactory.

Weiterer Nachteil ist, daß- wenn das Schlaufenband mit den dazugehörenden Schlaufen schräg auf den Vorhang aufgenäht wurde - das zugeordnete, schnurförmige Zugelement ebenfalls während des Raff-Vorganges schräg auf die Wickelspule aufgewickelt wurde und sich hierdurch in besonders nachteiliger Weise die Wickellagen auf der Wickelspule übereinanderhäuften, so daß beim Raffen der gesamte Vorhang in optischer unschöner Weise schiefhing.Another disadvantage is that - if the loop band with the associated loops was sewn diagonally onto the curtain - the associated cord-shaped tension element was also diagonally wound onto the winding spool during the gathering process, and the winding layers on the winding spool thereby piled up in a particularly disadvantageous manner , so that the entire curtain was crooked in a visually unsightly manner when the blinds were gathered.

Die vorliegende Erfindung hat sich ausgehend von einem Gegenstand der eingangs genannten Art die Aufgabe gestellt, einen solchen Raff-Vorhang so weiterzubilden, daß er wesentlich leichter und betriebssicherer zu bedienen ist.Starting from an object of the type mentioned at the outset, the present invention has set itself the task of developing such a venetian blind so that it is much lighter and more reliable is operate.

Zur Lösung der gestellten Aufgabe dient die im Anspruch 1 gegebene technische Lehre.The technical teaching given in claim 1 serves to solve the problem.

Wesentliches Merkmal ist, daß wegen der Verwendung von Zugelementen mit rechteckigem Querschnitt und Wickelspulen, auf denen die Zugelemente geordnet aufgewickelt werden, nun eine bessere Raffung des Vorhanges möglich ist. Es kann nun nicht mehr vorkommen, daß die Wickellagen kreuz und quer übereinander zu liegen kommen, so daß sich bei einer Wickelspule das Zugelement stärker verkürzt als bei der benachbarten Wickelspule.An essential feature is that because of the use of tension elements with a rectangular cross-section and winding spools on which the tension elements are wound up in an orderly manner, a better gathering of the curtain is now possible. It can no longer happen that the winding layers come to lie criss-cross one above the other, so that the tension element is shortened more in one winding spool than in the adjacent winding spool.

Auch, wenn das Schlaufenband, durch dessen Schlaufen das Zugelement geführt ist, versehentlich schräg aufgenäht ist, wird durch axiale Verschiebung der Wickelspulen auf der Wickelwelle erreicht, daß die Wickelspulen einem seitlichen, axialen Zug nachgeben und sich hierdurch auf der Wickelwelle verschieben, wodurch eine schräge Ausrichtung der Zugelemente ausgeglichen wird.Even if the loop band, through the loops of which the tension element is accidentally sewn on at an angle, it is achieved by axial displacement of the winding spools on the winding shaft that the winding spools give way to a lateral, axial pull and thereby shift on the winding shaft, causing an oblique Alignment of the tension elements is compensated.

Nach einer Weiterbildung des Erfindungsgedankens ist es nach Anspruch 2 vorgesehen, daß das auf Zugband durch feste, nicht verdrehbare Schlaufen des Schlaufenbandes geführt ist. Hierdurch wird der Raff-Vorgang wesentlich erleichtert, denn die vorher gegebene, starke Reibung an den verdrehbaren, schnurförmigen Schlaufen des Schlaufenbandes wird nun vermieden, indem feste, nicht verdrehbare Schlaufen vorgesehen sind.According to a further development of the inventive concept, it is provided according to claim 2 that the on the drawstring is guided by fixed, non-rotatable loops of the loop band. This makes the gathering process much easier, because the previously given strong friction on the twistable, cord-shaped loops of the loop band is now avoided by providing fixed, non-twistable loops.

In einer bevorzugten Ausgestaltung nach dem Gegenstand des Anspruches 3 ist es hierbei vorgesehen, daß die Schlaufen als Bandführungselemente aus einem biegsamen Kunststoffmaterial ausgebildet sind, und und das Aufzugband durch eine Ausnehmung mit annähernd rechteckiger öffnung leicht verschiebbar geführt ist. Hierdurch wird der geforderte reibungsarme Lauf des Aufzugbandes durch das Bandführungselement gewährleistet. Ferner ist wesentlich, daß die Bandführungselemente nun auswechselbar am Schlaufenband sind und leicht umsteckbar sind, so daß der Benutzer am Ort des Einbaus den gewünschten Raffabstand selbst einstellen kann. Hierzu ist es vorgesehen, daß am Bandführungselement ein Schlitz angeordnet ist, dessen eine Begrenzung durch einen federndenSchenkel gebildet ist, der mit seinem widerhakenartigen Kopf eine öffnung zum Schlitz federnd verschließt. Hierdurch ist es möglich, das Bandführungselement lösbar mit den Schlaufen eines herkömmlichen Gardinenbandes zu verbinden.In a preferred embodiment according to the subject matter of claim 3, it is provided that the loops are designed as tape guide elements made of a flexible plastic material, and and the elevator belt is easily displaceably guided through a recess with an approximately rectangular opening. In this way, the required low-friction running of the A ufzugbandes is ensured by the tape guide member. It is also essential that the tape guide elements are now interchangeable on the loop tape and are easily reversible so that the user can set the desired gathering distance himself at the place of installation. For this purpose, it is provided that a slot is arranged on the tape guide element, the boundary of which is formed by a resilient leg which resiliently closes an opening to the slot with its barb-like head. This makes it possible to releasably connect the tape guide element to the loops of a conventional curtain tape.

Bei der Anordnung des Standes der Technik war ein Schlaufenband mit fest vorgegebenen Schlaufen vorgesehen, was verbot, die Schlaufenabstände zu wechseln. Bei der Erfindung wird statt eines relativ kostspielig zu konfektionierenden Schlaufenbandes ein herkömmliches Gardinenband verwendet, so wie es in horizontaler Richtung an herkömmlichen Gardinen angenäht wird, wobei durch die Schlaufen entsprechende Gardinenrollring gezogen werden, die in entsprechenden Nuten von Vorhangschienen laufen.In the arrangement of the prior art, a loop band with fixed loops was provided, which prohibited changing the loop spacing. In the invention, instead of a relatively expensive loop tape to be assembled, a conventional curtain tape is used, as is sewn on conventional curtains in the horizontal direction, with corresponding curtain roller rings being drawn through the loops, which run in corresponding grooves of curtain rails.

Ein solches Gardinenband wird nun in vertikaler Richtung an dem Raff-Vorhang angenäht und in die darin eingearbeiteten Schlaufen werden die Bandführungselemente eingeschlauft.Such a curtain tape is now sewn on the vertical curtain and the tape guide elements are looped into the loops incorporated into it.

Weitere Merkmale der Erfindung sind Gegenstand der übrigen Unteransprüche.Further features of the invention are the subject of the remaining subclaims.

Der Erfindungsgegenstand der vorliegenden Erfindung ergibt sich nicht nur aus dem Gegenstand der einzelnen Patentansprüche, sondern auch aus der Kombination der einzelnen Patentansprüche untereinander.The subject matter of the present invention results not only from the subject matter of the individual claims, but also from the combination of the individual claims among themselves.

In nicht näher dargestellter Weise ist ein Raff-Vorhang 1 an seiner oberen Seite mit einer Profilschiene 25 verbunden. Die Profilschiene 25 ist mit einer Kunststoffhalterung 26 verbunden, mit der sie an einer Wand oder einer Decke festgemacht ist. In das untere Profil der Profilschiene 25 greifen Lagerböcke 18,21 ein, zwischen denen eine Wickelwelle 16 drehbar gelagert ist. Die Wickelwelle 16 ist einseitig aus dem Lagerbock 21 herausgeführt und dort drehfest mit einer Antriebsscheibe 23 verbunden, die im Gehäuse einer Aufzugrichtung 22 integriert ist. Die Antriebsscheibe 23 dient zum formschlüssigen Eingriff einer Kugelkette 24, die in nicht näher dargestellter Weise als geschlossene Schlaufe ausgeführt ist. Durch Zug an der Kugelkette 24 wird die Antriebsscheibe 23 ohne Schlupf gedreht und damit wird die Wickelwelle 16 mitgenommen.In a manner not shown, a gathering curtain 1 is connected to a profile rail 25 on its upper side. The rail 25 is connected to a plastic bracket 26 with which it is attached to a wall or a ceiling. In the lower profile of the Profile rail 25 engage bearing blocks 18, 21, between which a winding shaft 16 is rotatably mounted. The winding shaft 16 is guided on one side out of the bearing block 21 and is connected there in a rotationally fixed manner to a drive pulley 23 which is integrated in the housing of an elevator direction 22. The drive pulley 23 is used for positive engagement of a ball chain 24, which is designed in a manner not shown as a closed loop. By pulling on the ball chain 24, the drive pulley 23 is rotated without slippage and the winding shaft 16 is thus taken along.

Drehfest mit der Wickelwelle 16 sind mehrere, im Abstand nebeneinander angeordnete Wickelspulen 14 verbunden, von denen lediglich eine in Figur 1 und Figur 2 gezeigt ist. Jede Wickelspule 14 besteht aus zwei - einen gegenseitigen Abstand aufweisenden - Flanschen 15, wobei die Wickelspule 14 in den Pfeilrichtungen 17 axial auf der Wickelwelle 16 verschiebbar ist. Die linke Begrenzung der Verschiebung bildet hierbei der Lagerblock 18, während die rechte Begrenzung durch einen Stellring 19 gebildet ist, der klemmend, jedoch axial verschiebbar auf der Wickelwelle 16 gelagert ist.A plurality of winding coils 14, which are arranged next to one another at a distance from one another, of which only one is shown in FIG. 1 and FIG. 2, are connected in a rotationally fixed manner to the winding shaft 16. Each winding spool 14 consists of two flanges 15, which are at a mutual distance, the winding spool 14 being axially displaceable on the winding shaft 16 in the arrow directions 17. The left-hand limitation of the displacement here forms the bearing block 18, while the right-hand limitation is formed by an adjusting ring 19 which is mounted on the winding shaft 16 in a clamping but axially displaceable manner.

Vertikal am Raff-Vorhang 1 ist ein Schlaufenband 2 befestigt, was als herkömmliches Gardinenband ausgebildet ist. Hierdurch ergibt sich der Vorteil, daß die Schlaufen 3 in relativ engem Abstand zueinander angeordnet sind, und der Benutzer verschiedene Schlaufenabstände wählen kann. Die Abstände 4 zwischen den Schlaufen 3 sind also dadurch wählbar, daß der Benutzer bei Veränderung des Raffabstandes andere Schlaufen aus dem Schlaufenband 2 herausholt und dort die in Figur 1 - 3 dargestellten Bandführungselemente 5 einschlauft.A loop band 2 is fastened vertically to the gathering curtain 1, which is designed as a conventional curtain band. This has the advantage that the loops 3 are arranged at a relatively close distance from one another, and the user can choose different loop distances. The distances 4 between the loops 3 can thus be selected by the user taking other loops out of the loop band 2 when changing the gathering distance and looping in the band guide elements 5 shown in FIGS. 1-3.

Das in Fig. 3 dargestellte Bandführungselement 5 besteht aus einem unteren, federnden Schenkel 6, der vorne einen mit Widerhaken versehenen Kopf 7 aufweist, wobei in Richtung zum Körper des Bandführungselements 5 ein Schlitz 9 vorgesehen ist. Zur Verbindung des Bandführungselementes 5 mit dem Schlaufenband 2 wird der Kopf 7 gegen die Schlaufe 3 geführt, wobei der Schenkel 6 federnd nach unten ausweicht, und der Widerhaken am Kopf 7 kurzfristig den Schlitz 9 nach der Stirnseite hin freigibt, so daß die Schlaufe 3 in den Schlitz 9 einrastet und dort lagengesichert ist. Das Bandführungselement 5 ist damit unverschiebbar, jedoch lösbar, mit der Schlaufe 3 des Schlaufenbandes 2 verbunden und das Bandführungselement 5 ist damit unverdrehbar mit der Schlaufe verbunden, wodurch eine Verkantung mit Verbindung mit dem durch die Ausnehmung 10 hindurchgezogenen Aufzugband 13 vermieden wird.The band guide element 5 shown in FIG. 3 consists of a lower, resilient leg 6, which has a barbed head 7 at the front, a slot 9 being provided in the direction of the body of the tape guide element 5. To connect the band guide element 5 with the loop band 2, the head 7 is guided against the loop 3, the leg 6 springing downward and the barb on the head 7 briefly releases the slot 9 towards the front, so that the loop 3 in the slot 9 engages and is secured there. The tape guide element 5 is thus immovable, but detachable, connected to the loop 3 of the loop tape 2 and the tape guide element 5 is thus non-rotatably connected to the loop, thereby preventing canting with connection to the elevator tape 13 drawn through the recess 10.

Im Körper 8 des Bandführungselementes 5 ist eine weitere Ausnehmung 10 angeordnet, die aus einem länglichen Schlitz 11 mit einer etwa mittig daran ansetzenden Ausnehmung 12 besteht. Das Aufzugband 13 wird durch diesen Schlitz 11 eingefädelt. In einer Weiterbildung der Erfindung ist es vorgesehen, daß entsprechend der Anordnung des Schlitzes 9 auch der Schlitz 11 seitlich offen ist, um das Aufzugband 13 leichter in den Schlitz 11 einzufädeln. Die Schlitzbreite des Schlitzes 11 ist geringfügig größer als die Breite des Aufzugbandes 13, so daß es leichtgängig durch den Schlitz 11 hindurchgeführt ist und hiermit der eingangs beschriebene, leichte Lauf des Raff-Vorhanges während des Raff-Vorganges erreicht wird.In the body 8 of the tape guide element 5, a further recess 10 is arranged, which consists of an elongated slot 11 with an approximately centrally attached recess 12. The elevator belt 13 is threaded through this slot 11. In a further development of the invention, it is provided that according to the arrangement of the slot 9, the slot 11 is also open laterally in order to thread the elevator belt 13 more easily into the slot 11. The slot width of the slot 11 is slightly larger than the width of the elevator belt 13, so that it passes easily through the slot 11 and thus the smooth running of the gathering curtain described above is achieved during the gathering process.

Die Ausnehmung 12 dient dem Zweck der Verankerung des Aufzugbandes 13 am unteren Teil des Raff-Vorhanges 1. Dort wird das Aufzugband 13 mit dem untersten Bandführungselement 5 dadurch verbunden, daß im Aufzugband 13 ein Knoten gemacht wird, und der Knoten in die Ausnehmung 10 eingeführt wird, wodurch sich an die obere Ausnehmung 12 er klemmend anlegt.The recess 12 serves the purpose of anchoring the elevator belt 13 to the lower part of the Raff curtain 1. There the elevator belt 13 is connected to the lowest belt guide element 5 by making a knot in the elevator belt 13 and the knot in the off Take 10 is introduced, whereby he puts on the upper recess 12 clamping.

Hierdurch ist eine einfache-Befestigung des Aufzugbandes 13 gewährleistet, jederzeit wieder gelöst werden kann, indem der Knoten aus dem Schlitz 11 herausgezogen wird.This ensures simple fastening of the elevator belt 13, which can be undone at any time by pulling the knot out of the slot 11.

Das Aufzugband 13 wird hierbei zwischen den Flanschen 15 der Wickelspule 14 aufgenommen, wobei die Flansche 15 einen nur geringfügig größeren Abstand aufweisen, als es der Breite des Aufzugbandes 13 entspricht. Hierdurch besteht der Vorteil, daß bei nebeneinanderliegenden Wickelspulen 14 eine genaue synchrone Verkürzung des Aufzugbandes 13 beim Hochziehen des Raff-vorhanges erfolgt und damit eine schräge Faltenbildung, sowie ein Verkanten oder schiefes Hochziehen vermieden wird.The elevator belt 13 is received between the flanges 15 of the winding spool 14, the flanges 15 being only slightly larger apart than the width of the elevator belt 13. This has the advantage that with adjacent winding spools 14 there is a precise synchronous shortening of the elevator belt 13 when the curtain is pulled up, thus avoiding oblique wrinkling and canting or skewed pulling up.

Weiteres Merkmal ist, daß die Wickelspule 14 auf der Wickelwelle 16 mit axialem Spiel in den Pfeilrichtungen 17 verschiebbar gelagert ist, so daß auch - wenn das Schlaufenband 2 schräg aufgenäht werden sollte, und damit das Aufzugband 13 schräg gerichtet auf die Wickelspulen 14 aufgewickelt wird - die jeweilige Wickelspule 14 in den Pfeilrichtungen 17 axial ausweicht und damit stets ein gerades Aufwickeln des Aufzugbandes 13 gewährleistet ist.Another feature is that the winding spool 14 is slidably mounted on the winding shaft 16 with axial play in the arrow directions 17, so that - even if the loop band 2 should be sewn on at an angle, and thus the winding band 13 is wound obliquely onto the winding spools 14 - the respective winding spool 14 deviates axially in the arrow directions 17 and thus a straight winding of the elevator belt 13 is always guaranteed.

Die Wickelspule 14 ist drehfest mit der Wickelwelle 16 dadurch verbunden, daß gemäss Figur 2 die Wickelwelle 16 aus einem Dreikantprofil besteht, in das die Wickelspule 14 mit entsprechenden Vorsprüngen in die zurückspringenden Nuten der Wickelwelle 16 eingreift.The winding spool 14 is connected in a rotationally fixed manner to the winding shaft 16 in that, according to FIG. 2, the winding shaft 16 consists of a triangular profile into which the winding spool 14 engages with corresponding projections in the recessed grooves of the winding shaft 16.

Weiteres wesentliches Merkmal ist, daß stets nur ein einziger Lagerbock 18 einer Wickelspule 14 zugeordnet ist, während auf der gegenüberliegenden Seite ein in Pfeilrichtung 17 klemmend verstellbarer Stellring 19 auf der Wickelwelle 16 angebracht ist. Hierdurch wird wesentliches Material gespart, weil nur ein einziger Lagerbock verwendet wird und der Stellring 19 selbst sehr kostengünstig herzustellen ist.Another essential feature is that only a single bracket 18 is assigned to a winding spool 14 is, while on the opposite side in the direction of arrow 17 adjustable adjusting ring 19 is attached to the winding shaft 16. This saves essential material because only a single bearing block is used and the adjusting ring 19 itself can be manufactured very inexpensively.

Die Befestigung des Aufzugbandes 13 auf der Wickelspule 14 erfolgt gemäss Figur 4 dadurch, daß in der Wickelspule 14 ein radialer Schlitz 20 in mindestens einem Flansch 15 angeordnet ist. Im Aufzugband 13 wird ein Knoten eingeknüpft, der seitlich aus dem Schlitz 20 im Flansch 15 herausgeführt wird, wobei sich der Knoten außen an den Flansch 15 anlegt. Der Schlitz 20 geht hierbei - wie in Figur 2 dargestellt - bis zum Grund der Wickelspule 14, so daß sich der Knoten klemmend an den Flansch 15 anlegt. In der in Fig. 5 und 6 gezeigten weiteren Ausführungsform wird dargestellt, wie ein Antriebsmotor 27 im Bereich der Raff-Einrichtung integriert ist.According to FIG. 4, the elevator belt 13 is fastened on the winding spool 14 in that a radial slot 20 is arranged in the winding spool 14 in at least one flange 15. A knot is tied in the elevator belt 13 and is led out laterally from the slot 20 in the flange 15, the knot resting against the flange 15 on the outside. The slot 20 extends - as shown in Figure 2 - to the bottom of the winding spool 14, so that the knot is clamped against the flange 15. 5 and 6 show how a drive motor 27 is integrated in the area of the gathering device.

Bei den Anordnungen des Standes der Technik war es bisher nur bekannt, einen solchen Antriebsmotor 27 außerhalb der Raff-Einrichtung, beispielsweise im Bereich der Kugelkette 24, anzuordnen. Hierbei war der Antriebsmotor gesondert an der Wand befestigt, und musste über eigene Zugmittelgetriebe mit der Antriebsscheibe 23 der Aufzugvorrichtung 22 verbunden werden.In the arrangements of the prior art, it was previously only known to arrange such a drive motor 27 outside the R aff device, for example in the region of the ball chain 24. Here, the drive motor was separately attached to the wall and had to be connected to the drive pulley 23 of the elevator device 22 via its own traction mechanism.

Bei der Ausführungsform nach Fig. 5 ist der Antriebsmotor 27 unmittelbar in die Wickelwelle 16 integriert. Hierdurch ergibt sich der Vorteil, daß der Antriebsmotor 27 hinter dem Raff-Vorhang verborgen direkt an einer Profilschiene 35 befestigt ist, und über Lagerböcke 30, die in entsprechende Profilnuten 29 der Profilschiene 35 eingreifen, befestigt ist. Hierdurch ist es möglich, den Antriebsmotor 27 durch Verschiebung der Lagerböcke 30 im Bereich der Profilnuten 29 entsprechend den Erfordernissen am Einbauort zu verschieben. Die Kraftübertragung ist auch wesentlich günstiger, denn der Antriebsmotor 27 kann seine Kraft unmittelbar auf die Wickelwelle 16 übertragen, nachdem entsprechende, zwischengeschaltete Zugmittelgetriebe entfallen.In the embodiment according to FIG. 5, the drive motor 27 is integrated directly into the winding shaft 16. This has the advantage that the drive motor 27 is hidden behind the tieback and is fastened directly to a profile rail 35, and is fastened via bearing blocks 30 which engage in corresponding profile grooves 29 in the profile rail 35. This is it possible to move the drive motor 27 by moving the bearing blocks 30 in the region of the profile grooves 29 according to the requirements at the installation site. The power transmission is also considerably cheaper, since the drive motor 27 can transmit its power directly to the winding shaft 16 after corresponding intermediate traction mechanism transmissions are eliminated.

In nicht näher dargestellter Weise kann der Antriebsmotor 27 bei den Positionen 28 von nicht näher dargestellten Lagerböcken eingefasst werden, wobei die Lagerböcke drehbar die Wickelwelle 16 aufnehmen und die Lagerung mit Hilfe von Kugellagern oder Gleitlagern erfolgt.In a manner not shown, the drive motor 27 can be framed at positions 28 by bearing blocks, not shown, the bearing blocks rotatably receiving the winding shaft 16 and the bearing being carried out with the aid of ball bearings or plain bearings.

Durch die Verschiebung der Lagerböcke 18,21,30 im Bereich der Nuten der Profilschiene 25,35 ist es möglich, in einem baukastenartigen System beliebig viele Wickelspulen-nebeneinander in gegenseitigem Abstand auf der Wickelwelle anzuordnen.By displacing the bearing blocks 18, 21, 30 in the region of the grooves of the profiled rail 25, 35, it is possible to arrange any number of winding spools next to one another at a mutual distance on the winding shaft in a modular system.
