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 Raffvorhang mit den Merkmalen gemäß dem Oberbegriff von Patentanspruch 1.The invention relates to a Roman blind with the features according to the preamble of patent claim 1.

Einen derartigen Raffvorhang beschreibt die US-A-2 676 654. Dort sind die Wickelspulen auf ihrer Wickelwelle fest verkeilt. Damit ist aber der Nachteil verbunden, daß bei einer versehentlichen Schrägführung des Schlaufenbandes die Zugelemente ebenfalls schräg laufen. Dies ist aber bei einem derartigen Raffvorhang nicht nur ästhetisch unschön, sondern kann sogar zu einem Verklammen der Zugelemente auf den Wickelspulen führen.Such a gathering curtain is described in US Pat. No. 2,676,654. There, the winding coils are firmly wedged on their winding shaft. However, this has the disadvantage that if the loop band is inadvertently inclined, the tension elements also run obliquely. However, this is not only aesthetically unattractive with such a Roman blind, but can even lead to jamming of the tension elements on the winding spools.

Der Erfindung liegt daher die Aufgabe zugrunde, einen Raffvorhang mit den Merkmalen des Oberbegriffs von Patentanspruch 1 dahingehend weiterzubilden, daß durch einfache konstruktive Mittel für ein einwandfreies Aufspulen der Aufzugbänder auf ihre Wickelspulen gesorgt ist.The invention is therefore based on the object of developing a roman blind with the features of the preamble of claim 1 to the effect that a simple winding of the winding belts onto their winding spools is ensured by simple design means.

Die Lösung dieser Aufgabe erfolgt durch die kennzeichnenden Merkmale von Patentanspruch 1. Dadurch wird dafür gesorgt, daß das Aufzugband stets lotrecht fluchtend zu seiner Wickelspule aufgewickelt bzw. abgewickelt wird. Hiermit wirkt zusammen, daß die Schlaufen die Lotrechtführung unterstützen, die vertikal in Fluchtlinie zur Wickelspule verlaufen.This object is achieved by the characterizing features of patent claim 1. This ensures that the elevator belt is always wound up or unwound in a flush manner with respect to its winding spool. This interacts with the fact that the loops support vertical guidance, which run vertically in line with the winding spool.

Die abhängigen, Ansprüche 2 bis 5 sind auf bevorzugte Maßnahmen gerichtet, die zur Lösung der Erfindungsaufgabe dienlich sind.The dependent claims 2 to 5 are directed to preferred measures which are useful for solving the object of the invention.

Im folgenden wird die Erfindung anhand von lediglich einen Ausführungsweg darstellende Zeichnungen näher erläutert.The invention is explained in more detail below with the aid of drawings which illustrate only one embodiment.

In nicht näher dargestellter Weise ist ein Raffvorhang 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 Aufzugeinrichtung 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 Roman blind 1 is connected on its upper side to a profile rail 25. The rail 25 is connected to a plastic bracket 26 with which it is attached to a wall or a ceiling. Bearing blocks 18, 21 engage in the lower profile of the profile rail 25, between which a winding shaft 16 is rotatably mounted. The winding shaft 16 is guided out of the bearing block 21 on one side and is connected there in a rotationally fixed manner to a drive pulley 23 which is integrated in the housing of an elevator device 22. The drive pulley 23 is used for positive engagement of a ball chain 24, which is designed as a closed loop in a manner not shown. 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 Lagerbock 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 limit of the displacement forms the bearing block 18, while the right limit is formed by an adjusting ring 19 which is mounted on the winding shaft 16 in a clamping but axially displaceable manner.

Vertikal am Raffvorhang 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 roman blind 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 removing other loops from the loop band 2 when changing the gathering distance and looping in the band guide elements 5 shown in FIGS. 1-3.

Das in Figur 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 Bandführungselements 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 tape 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 side, so that the loop 3 in the slot 9 engages and is secured there. The band guide element 5 is thus immovable, but releasable, connected to the loop 3 of the loop band 2 and the band guide element 5 is thus non-rotatably connected to the loop, thereby preventing jamming with connection to the elevator band 13 drawn through the recess 10.

In Körper 8 des Bandführungselementes 5 ist eine 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. Entsprechend der Anordnung des Schlitzes 9 ist auch der Schlitz 11 seitlich offen, um das Aufzugband 13 leichter in den Schlitz 11 einzufädein. 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 Raffvorhangs während des Raffvorganges erreicht wird.A recess 10 is arranged in the body 8 of the band guiding element 5 and consists of an elongated slot 11 with a recess 12 which is approximately centered thereon. The elevator belt 13 is threaded through this slot 11. 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 is easily passed through the slot 11 and thus the entrance described smooth running of the venetian blind is achieved during the gathering process.

Die Ausnehmung 12 dient dem Zweck der Verankerung des Aufzugbandes 13 am unteren Teil des Raffvorhanges 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 er sich die obere Ausnehmung 12 klemmend anlegt.The recess 12 serves the purpose of anchoring the elevator belt 13 to the lower part of the gathering 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 inserting the knot into the recess 10, whereby he creates the upper recess 12 by 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 released 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 nebeneinander liegenden Wickelspulen 14 eine genaue synchrone Verkürzung des Aufzugbandes 13 beim Hochziehen des Raffvorhanges erfolgt und damit eine schräge Faltenbildung, sowie ein Verkanten oder schiefes Hochziehen vermieden wird.In this case, the elevator belt 13 is received between the flanges 15 of the winding spool 14, the flanges 15 being only slightly greater apart than the width of the elevator belt 13. This has the advantage that with winding coils 14 lying next to one another there is a precise synchronous shortening of the elevator belt 13 when the shirring curtain is raised, thus avoiding oblique wrinkling and canting or skewing upward.

Die Wickelspule 14 ist auf der Wickelwelle 16 mit axialem Spiel in den Pfeilrichtungen 17 verschiebbar gelagert, 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.The winding spool 14 is slidably mounted on the winding shaft 16 with axial play in the direction of the arrows 17, so that - if the loop band 2 should be sewn on obliquely, and thus the winding band 13 is wound obliquely onto the winding spools 14 - the respective winding spool 14 in deviates axially from 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.

Stets ist nur ein einziger Lagerbock 18 einer Wickelspule 14 zugeordnet, während auf der gegenüberliegenden Seite ein in Pfeilrichtung 17 klemmend verstellbarer Stellring 19 auf der Wickelwelle 16 angebracht ist. Hierdurch wird Material eingespart, weil nur ein einziger Lagerbock verwendet wird und der Stellring 19 selbst sehr kostengünstig herzustellen ist.Only a single bearing block 18 is always assigned to a winding spool 14, while on the opposite side an adjusting ring 19, which is adjustable in the direction of the arrow 17, is attached to the winding shaft 16. This saves material because only a single bracket is used and the adjusting ring 19 itself is very inexpensive to manufacture.

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 die 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 Figur 5 und 6 gezeigten weiteren Ausführungsform wird dargestellt, wie ein Antriebsmotor 27 in die 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. The further embodiment shown in FIGS. 5 and 6 shows how a drive motor 27 is integrated in the device.

Bei der Ausführungsform nach Figur 5 ist der Antriebsmotor 27 unmittelbar in die Wickelwelle 16 integriert. Hierdurch ergibt sich der Vorteil, daß der Antriebsmotor 27 hinter dem Raffvorhang 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 roman blind and is attached directly to a profile rail 35, and is fixed via bearing blocks 30 which engage in corresponding profile grooves 29 of the profile rail 35. This makes it possible to move the drive motor 27 by moving the bearing blocks 30 in the region of the profile grooves 29 in accordance with 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 profile rail 25, 35, it is possible to arrange any number of winding spools next to one another at a mutual spacing on the winding shaft in a modular system.
