Definitions
- the invention relates to a device for winding the drawstrings of Raffvorhangs with the features specified in the preamble of claim 1.
- a generic device which has a profiled mounting rail with attached bearing elements which carry a winding shaft.
- a curtain track is attached to which distributed in the upper region over the width of several deflecting elements and perpendicularly spaced thereto in series Werner, Inc.
- the only pull cord here is laid U-shaped on the curtain track.
- deflection elements are also provided on the curtain track and Endbefest Trentsus for the single string.
- stationary coil-shaped winding elements On the winding shaft, which can be rotated by a bead band in both directions, stationary coil-shaped winding elements are provided, which have diametrically projecting outer legs which receive the parallel to the winding shaft extending drawstring portion during rotation and lead to the bobbin for wrapping.
- EP 1 081 327 A2 is proposed a winding roll with a fixed housing and a rotatably mounted therein winding core for receiving at least one pull cord.
- An axially movable thread guide member leads the drawstrings side by side on the winding core.
- the drawstrings are attached to the end of the bottom of the curtain and fanned out on the other side and wound side by side.
- This device is only suitable for single cords. This solution requires a lot of effort in the assembly and disassembly of the curtain. In addition, it is not guaranteed that the individual drawstrings are wound up in an orderly manner.
- the apparatus for orderly winding the drawstrings of a Roman blind has for each U-shaped pull cord two mounted on the winding shaft coils adjacent to each deflecting parallel to the horizontal part of the U-shaped pull cord.
- the coils each consist of a bobbin and a fixedly connected to the bobbin with a recess drive plate on one side and a fixed cheek on the other side, in which the bobbin is rotatably mounted.
- the coils are arranged between the deflecting elements of a pull cord on the winding shaft, that the driver disks protrude against.
- Both bobbins are equipped with a thread, one of the bobbin has a right-hand thread and the other bobbin has a left-hand thread.
- a slider On the bobbins, a slider is ever arranged with a recess which abut the entrafftened state of the curtain respectively on the drive plate and each slide in the direction of the fixed cheek on the thread of the bobbin when rotating the coils.
- the fixed cheek has a receptacle for the deflection and a guide for the pull cord.
- the parallel Ceischnate the U-shaped pull cord is inserted on both sides in the guides of the two cheeks, the recesses of the slider and the recesses of the drive plate during assembly of the curtain.
- the threads of the two coils preferably have a pitch corresponding to the diameter of the pull cord. Under this condition, the coil receives the smallest width for a certain length of the curtain.
- the width of the coils can be as easy as the length of the pull cords be adjusted so that a complete shirring of the curtain is possible.
- the sliders may have on the side facing the drive plate a cup-shaped extension which has at least a width which is equal to the width of the pull cord and which surrounds the first turn of the pull cord on the bobbin except for a narrow gap at the beginning of the turn ,
- the deflecting elements for the drawstring have a hook or an eyelet for deflecting the drawstring and are preferably fastened with a Velcro plate on Raffvorhang. But they can also be sewn to the curtain.
- the deflecting elements attached to the Roman shade are preferably designed to have a hook or loop for deflecting the drawstring and a plate intended for insertion into the receptacle of the fixed cheek of the coil.
- the shots of the two fixed cheeks can advantageously also be designed so that they receive the hook or the eye of the deflection.
- the receptacles may have an abrasion-resistant pull cord channel inside, from which the pull cord is taken over and guided during the insertion of the deflecting elements into the receptacle.
- the Switzerlandschnurkanal can be made of an abrasion resistant material, eg. As a plastic, or have a metal insert.
- the pull cord is lifted when inserting the hook or the eyelet of these and then slides only in Switzerlandschnurkanal.
- the bottom of the hook or eyelet when inserted into the receptacle of the fixed cheek, has the same or lower height than the abrasion resistant drawstring channel. The hook or the eyelet are then no longer burdened by the pull cord.
- the receptacle of the fixed cheek should have a width which corresponds approximately to the strength of the hook or eyelet, and the two sides of the receptacle have an inwardly sloping inwardly on which the drawstring slides when inserting the eyelet up into the Switzerlandschnurkanal , It is also possible that at least on the side of the receptacle at which the drawstring is guided on the curtain, a tongue is present, which engages under the pull cord when inserting the eyelet and lifts it into the Switzerlandschnurkanal. On the other hand, the pull cord has a horizontal position due to the U-shaped guide, so that support by a tongue is not required.
- symmetrically designed receptacles are advantageous because they can be used both on the right and on the left side of the U-shaped pull cords, so the left and the right coil.
- the tongue should be made of an abrasion-resistant material, since the pulling cord which is under tension when the curtain is shirred on it slides.
- nubs are provided in the receptacle, to which the deflecting element is clicked. When attaching the curtain to the curtain rail, these nubs may be advantageous because of the click noise, as this allows the secure hold of the curtain to be controlled during assembly.
- the better grip of the hooks or eyes of the deflection during assembly can also be achieved in that the deflection elements are designed to be elastic, so that they must be inserted with a certain tension in the recording and press in the inserted state against the walls of the recording.
- the deflecting elements can for this purpose have a vertically or horizontally undercut eyelet. But it is also conceivable to produce the eyelets made of an elastic material with a very small excess in relation to the recording.
- the decisive advantage of this transfer of the pull cord in a guide channel is that the pull cord no longer loads the deflection, whereby the deflection can be made of a very light and soft material.
- the coil in particular the fixed cheek of the coil, can be made very stable and resistant to abrasion. But it is also possible to produce only the Werschnurkanal of an abrasion-resistant plastic or to provide the Switzerlandschnurkanal with a metal insert.
- the curtain receives an exact lateral and height alignment when mounted on the elevator device.
- the drive plate may have a recess which is recessed in the direction opposite to the Aufwickelraum.
- the drawstring shifts as soon as the curtain is gathered.
- an elongated housing in which the winding shaft are arranged with the coils for all U-shaped pull cords.
- the device can then be completely installed in the housing prior to assembly.
- the housing has expediently an inner profile in which the cheeks are locked and the gliders can slide against rotation.
- the inventive device can also be used for single cords, if only one coil is used and the individually guided pull cord is attached to the drive plate. This use may be required if an odd number of drawstrings are present in a particular pattern of the curtain. However, then falls the advantage of easy assembly and disassembly away from the curtain.
- the curtain in which the drawstrings are guided in a U-shape, is mounted in the unraveled state.
- the deflecting elements are inserted into the receptacle of the fixed cheeks of the coils.
- the Roman shade is attached to the curtain rail by means of Velcro.
- the running parallel to the winding shaft part of the U-shaped pull cord is inserted into the guides of the cheeks, the recesses of the slider and the recesses of the drive plate.
- the decisive advantage of the solution lies in the fact that the pull cords are always mounted side by side on the bobbin, whereby the simple assembly and disassembly of the curtain is maintained. It is thereby avoided the uneven fitting of the individual drawstrings with the negative consequences of warping the curtain.
- Another decisive advantage comes from the constant force when shirring and releasing the curtain.
- the costly braking device on the winding shaft which is present in every Roman blind of the known type, can thereby be dispensed with.
- the elevator device is characterized on the one hand very quiet and on the other hand simpler in construction.
- Fig. 1 the device according to the present invention is shown schematically.

- a slider 12 On the bobbins 5, a slider 12 is arranged with a recess 14 which abuts the entrafftened state of the curtain on the drive plate 7 and which slides when turning the winding shaft 1 with the bobbin 5 respectively in the opposite direction on the thread 6 of the bobbin 5.
- the fixed cheek 9 has a receptacle 10 for the deflecting element 3 and a guide 11 for the pull cord 4.
- the parallel Buchschnate the U-shaped pull cord 4 is on both sides in the guides 11 of the two fixed cheeks 9, the recesses in the assembly of the curtain 14 of the slider 12 and the recesses 8 of the drive plate 7 inserted.
- the sliders 12 After assembly of the de-aired curtain on the device, the sliders 12 abut on the drive plate 7. As soon as the winding shaft 1 is rotated, the two driver disks 7 also rotate and take the pull cord 4, which lies in the recess 8, with. The pull cord is pulled into the thread 6 on the bobbin 5 and the slider 12 moves on the thread 6 in the direction away from the drive plate 7.

Description
Die Erfindung betrifft eine Vorrichtung zum Aufwickeln der Zugschnüre eines Raffvorhangs mit den im Oberbegriff des Anspruches 1 angegebenen Merkmalen.The invention relates to a device for winding the drawstrings of Raffvorhangs with the features specified in the preamble of
Aus der
Es ist ein bekanntes Problem der Raffvorhänge, in denen Zugschnüre geführt werden, die beim Raffen des Vorhangs auf eine Wickelwelle aufgewickelt werden, dass diese Zugschnüre in ungeordneten Lagen auf der Wickelwelle liegen.It is a known problem of Roman blinds, in which pull cords are guided, which are wound up when shirring the curtain on a winding shaft, that these pull cords are in disordered positions on the winding shaft.
Dadurch entstehen unterschiedliche Aufzugslängen der einzelnen Zugschnüre, die dazu führen, dass der Vorhang schief hängt oder ungleichmäßig aufgewickelt wird. Es werden deshalb seit Jahren Versuche unternommen, dieses Problem zu lösen.This results in different elevator lengths of the individual cords, which cause the curtain to hang obliquely or unevenly wound up. Therefore, attempts have been made for years to solve this problem.
Aus der
In dem
Diese Aufrollvorrichtungen haben zwei wesentliche Nachteile. Zum einen ist sie nicht geeignet, U-förmig geführte Zugschnüre aufzuwickeln und zum anderen wird das eine Ende der einzeln geführten Zugschnüre fest an die Aufrolltrommel eingeklickt. Bei der Montage des Raffvorhangs muss jede einzelne Aufhängeschnur per Hand an der Aufrolltrommel befestigt werden und beim Abnehmen des Raffvorhangs wieder per Hand gelöst werden.These retractors have two major disadvantages. For one, it is not suitable to wind up U-shaped guided pull cords and on the other hand, one end of the individually guided pull cords is firmly clicked on the reel drum. When assembling the Roman blind, each individual suspension cord must be manually attached to the reel drum and loosened by hand when removing the Roman shade.
In der Patentanmeldung
Außerdem sind bei diesen Lösungen größere technische Aufwendungen einschließlich einer geeigneten Bremse, um ein unfreiwilliges Entraffen des Vorhangs zu vermeiden, erforderlich.In addition, these solutions require greater engineering expenditures, including a suitable brake, to avoid involuntarily unhooking the curtain.
Es ist deshalb die Aufgabe der vorliegenden Erfindung, eine Vorrichtung vorzuschlagen, die das geordnete Aufwickeln einer in einem Raffvorhang U-förmig geführten Zugschnur beim Raffen des Vorhangs mit einfachen Mitteln erlaubt.It is therefore an object of the present invention to provide a device that allows the orderly winding a guided in a Roman shade U-shaped pull cord when shirring the curtain with simple means.
Die Aufgabe wird durch die Merkmale des Hauptanspruchs gelöst. Die Unteransprüche stellen spezielle Ausgestaltungen dar.The object is solved by the features of the main claim. The subclaims represent special embodiments.
Die Vorrichtung zum geordneten Aufwickeln der Zugschnüre eines Raffvorhangs entsprechend der vorliegenden Erfindung besitzt für jede U-förmig geführte Zugschnur zwei auf der Wickelwelle gelagerte Spulen angrenzend an jedes Umlenkelement parallel zum waagerechten Teil der U-förmig geführten Zugschnur. Die Spulen bestehen jeweils aus einem Spulenkörper und einer mit dem Spulenkörper fest verbundenen mit einer Aussparung versehenen Mitnehmerscheibe an der einen Seite und einer fest stehenden Wange an der anderen Seite, in der der Spulenkörper drehbar gelagert ist. Die Spulen sind so zwischen den Umlenkelementen einer Zugschnur auf der Wickelwelle angeordnet, dass sich die Mitnehmerscheiben gegen überstehen. Beide Spulenkörper sind mit einem Gewinde ausgerüstet, wobei der eine Spulenkörper ein Rechtsgewinde und der andere Spulenkörper ein Linksgewinde besitzt. Auf den Spulenkörpern ist je ein Gleiter mit einer Aussparung angeordnet, die im entrafften Zustand des Vorhangs jeweils an der Mitnehmerscheibe anliegen und beim Drehen der Spulen jeweils in Richtung der feststehenden Wange auf dem Gewinde des Spulenkörpers gleiten. Die feststehende Wange besitzt eine Aufnahme für das Umlenkelement und eine Führung für die Zugschnur. Der parallele Zugschnurteil der U förmig geführten Zugschnur wird bei der Montage des Vorhangs beidseitig in die Führungen der beiden Wangen, den Aussparungen der Gleiter und den Aussparungen der Mitnehmerscheibe eingelegt.The apparatus for orderly winding the drawstrings of a Roman blind according to the present invention has for each U-shaped pull cord two mounted on the winding shaft coils adjacent to each deflecting parallel to the horizontal part of the U-shaped pull cord. The coils each consist of a bobbin and a fixedly connected to the bobbin with a recess drive plate on one side and a fixed cheek on the other side, in which the bobbin is rotatably mounted. The coils are arranged between the deflecting elements of a pull cord on the winding shaft, that the driver disks protrude against. Both bobbins are equipped with a thread, one of the bobbin has a right-hand thread and the other bobbin has a left-hand thread. On the bobbins, a slider is ever arranged with a recess which abut the entrafftened state of the curtain respectively on the drive plate and each slide in the direction of the fixed cheek on the thread of the bobbin when rotating the coils. The fixed cheek has a receptacle for the deflection and a guide for the pull cord. The parallel Zugschnurteil the U-shaped pull cord is inserted on both sides in the guides of the two cheeks, the recesses of the slider and the recesses of the drive plate during assembly of the curtain.
Die Gewinde der beiden Spulen besitzen vorzugsweise eine Steigung, die dem Durchmesser der Zugschnur entspricht. Unter dieser Voraussetzung erhält die Spule für eine bestimmte Länge des Vorhangs die geringste Breite. Die Breite der Spulen kann so einfach der Länge der Zugschnüre angepasst werden, so dass ein vollständiges Raffen des Vorhangs möglich ist.The threads of the two coils preferably have a pitch corresponding to the diameter of the pull cord. Under this condition, the coil receives the smallest width for a certain length of the curtain. The width of the coils can be as easy as the length of the pull cords be adjusted so that a complete shirring of the curtain is possible.
Gemäß vorliegender Erfindung können die Gleiter an der der Mitnehmerscheibe zugewandten Seite eine schalenförmige Erweiterung besitzen, die mindestens eine Breite besitzt, die gleich der Breite der Zugschnur ist und die die erste Windung der Zugschnur auf dem Spulenkörper bis auf einen schmalen Spalt am Beginn der Windung umgibt. Dadurch wird mindestens die am Gleiter anliegende erste Windung der U-förmig geführten Zugschnur auf dem Spulenkörper gehalten, auch wenn die Wickeleinrichtung zwar gedreht wird, die Zugschnur aber nicht in den Vorhang eingezogen werden kann, weil der Vorhang z. B. auf einem Gegenstand aufliegt. Die Zugschnur fällt dann gleichmäßig neben dem Vorhang herab.According to the present invention, the sliders may have on the side facing the drive plate a cup-shaped extension which has at least a width which is equal to the width of the pull cord and which surrounds the first turn of the pull cord on the bobbin except for a narrow gap at the beginning of the turn , As a result, at least the voltage applied to the slider first turn of the U-shaped pull cord is held on the bobbin, even if the winding device is indeed rotated, but the pull cord can not be pulled into the curtain, because the curtain z. B. rests on an object. The drawstring then falls evenly down the curtain.
Der entscheidende Vorteil dieser schalenförmigen Erweiterung liegt darin, dass die nebeneinander auf dem Spulenkörper aufgezogene Zugschnur stets nacheinander gleichmäßig wieder abgewickelt wird, unabhängig davon, ob der Vorhang entlastet ist, weil er auf einem Gegenstand aufläuft oder ob an ihm nach unten gezogen wird. Es wird dadurch ein Verwirren der einzelnen Zugschnüre vermieden. Die Zugschnur läuft nacheinander von der Spule ab.The decisive advantage of this cup-shaped enlargement is that the pull cord pulled up next to one another on the bobbin is always unrolled uniformly one after the other, regardless of whether the curtain is relieved, because it runs on an object or if it is pulled down on it. It is thereby avoided confusion of the individual pull cords. The pull cord runs one after the other from the spool.
Die Umlenkelemente für die Zugschnur besitzen einen Haken oder eine Öse zur Umlenkung der Zugschnur und sind vorzugsweise mit einer Klettplatte am Raffvorhang befestigt. Sie können aber auch an den Vorhang angenäht werden. Die am Raffvorhang befestigten Umlenkelemente sind vorzugsweise so gestaltet, dass sie einen Haken oder eine Öse zum Umlenken der Zugschnur und eine Platte besitzen, die zur Einführung in die Aufnahme der feststehenden Wange der Spule vorgesehen ist.The deflecting elements for the drawstring have a hook or an eyelet for deflecting the drawstring and are preferably fastened with a Velcro plate on Raffvorhang. But they can also be sewn to the curtain. The deflecting elements attached to the Roman shade are preferably designed to have a hook or loop for deflecting the drawstring and a plate intended for insertion into the receptacle of the fixed cheek of the coil.
Die Aufnahmen der beiden feststehenden Wangen können vorteilhafterweise auch so ausgebildet sein, dass sie den Haken oder die Öse des Umlenkelementes aufnehmen. In diesem Fall können die Aufnahmen im Inneren einen abriebfesten Zugschnurkanal aufweisen, von dem die Zugschnur beim Einführen der Umlenkelemente in die Aufnahme übernommen und geführt wird. Der Zugschnurkanal kann aus einem abriebfesten Material, z. B. einem Kunststoff, bestehen oder eine Metalleinlage besitzen.The shots of the two fixed cheeks can advantageously also be designed so that they receive the hook or the eye of the deflection. In this case, the receptacles may have an abrasion-resistant pull cord channel inside, from which the pull cord is taken over and guided during the insertion of the deflecting elements into the receptacle. The Zugschnurkanal can be made of an abrasion resistant material, eg. As a plastic, or have a metal insert.
Die Zugschnur wird beim Einschieben des Hakens oder der Öse von diesen abgehoben und gleitet dann ausschließlich im Zugschnurkanal. Der Boden des Hakens oder der Öse besitzt im eingeführten Zustand in die Aufnahme der feststehenden Wange die gleiche oder eine geringere Höhe als der abriebfeste Zugschnurkanal. Der Haken oder die Öse werden dann nicht mehr durch die Zugschnur belastet.The pull cord is lifted when inserting the hook or the eyelet of these and then slides only in Zugschnurkanal. The bottom of the hook or eyelet, when inserted into the receptacle of the fixed cheek, has the same or lower height than the abrasion resistant drawstring channel. The hook or the eyelet are then no longer burdened by the pull cord.
Die Aufnahme der feststehenden Wange sollte eine Breite besitzen, die etwa der Stärke des Hakens oder der Öse entspricht, und die beiden Seiten der Aufnahme weisen nach innen eine nach innen ansteigende Schräge auf, auf der die Zugschnur beim Einschieben der Öse aufwärts in den Zugschnurkanal gleitet. Es ist auch möglich, dass mindestens an der Seite der Aufnahme, an der die Zugschnur am Vorhang geführt ist, eine Zunge vorhanden ist, die beim Einschieben der Öse unter die Zugschnur greift und diese in den Zugschnurkanal hebt. An der anderen Seite besitzt nämlich die Zugschnur aufgrund der U-förmigen Führung eine waagerechte Lage, so dass eine Unterstützung durch eine Zunge nicht erforderlich ist. Aus ökonomischer Sicht sind jedoch symmetrisch ausgeführte Aufnahmen vorteilhaft, da sie sowohl an der rechten als auch an der linken Seite der U-förmig geführten Zugschnüre, also der linken als auch der rechten Spule, eingesetzt werden können. Die Zunge sollte aus einem abriebfesten Material bestehen, da die beim Raffen des Vorhangs unter Spannung stehende Zugschnur auf ihr gleitet.The receptacle of the fixed cheek should have a width which corresponds approximately to the strength of the hook or eyelet, and the two sides of the receptacle have an inwardly sloping inwardly on which the drawstring slides when inserting the eyelet up into the Zugschnurkanal , It is also possible that at least on the side of the receptacle at which the drawstring is guided on the curtain, a tongue is present, which engages under the pull cord when inserting the eyelet and lifts it into the Zugschnurkanal. On the other hand, the pull cord has a horizontal position due to the U-shaped guide, so that support by a tongue is not required. From an economic point of view, however, symmetrically designed receptacles are advantageous because they can be used both on the right and on the left side of the U-shaped pull cords, so the left and the right coil. The tongue should be made of an abrasion-resistant material, since the pulling cord which is under tension when the curtain is shirred on it slides.
Es hat sich gezeigt, dass die Umlenkelemente durch das Eigengewicht des Raffvorhangs sicher in der Aufnahme der feststehenden Wangen verbleiben. Es kann trotzdem vorgesehen werden, dass in der Aufnahme Noppen vorgesehen sind, an die das Umlenkelement eingeklickt wird. Beim Befestigen des Vorhangs an der Vorhangleiste können diese Noppen wegen des Klickgeräusches vorteilhaft sein, da dadurch während der Montage der sichere Halt des Vorhangs kontrolliert werden kann.It has been shown that the deflecting elements safely remain in the receptacle of the fixed cheeks by the weight of the Roman shade. It can nevertheless be provided that nubs are provided in the receptacle, to which the deflecting element is clicked. When attaching the curtain to the curtain rail, these nubs may be advantageous because of the click noise, as this allows the secure hold of the curtain to be controlled during assembly.
Der bessere Halt der Haken oder Ösen der Umlenkelemente während der Montage kann auch dadurch erreicht werden, dass die Umlenkelemente elastisch gestaltet werden, so dass sie mit einer gewissen Spannung in die Aufnahme eingeschoben werden müssen und im eingelegten Zustand gegen die Wandungen der Aufnahme drücken. Die Umlenkelemente können dazu eine senkrecht oder waagerecht unterhöhlte Öse besitzen. Es ist aber auch denkbar, die aus einem elastischen Material hergestellten Ösen mit einem sehr geringen Übermaß in Bezug auf die Aufnahme herzustellen.The better grip of the hooks or eyes of the deflection during assembly can also be achieved in that the deflection elements are designed to be elastic, so that they must be inserted with a certain tension in the recording and press in the inserted state against the walls of the recording. The deflecting elements can for this purpose have a vertically or horizontally undercut eyelet. But it is also conceivable to produce the eyelets made of an elastic material with a very small excess in relation to the recording.
Der entscheidende Vorteil dieser Übergabe der Zugschnur in einen Führungskanal besteht darin, dass die Zugschnur die Umlenkelemente nicht mehr belastet, wodurch die Umlenkelemente aus einem sehr leichten und weichen Material gefertigt werden können. Die Spule, insbesondere die feststehende Wange der Spule, kann sehr stabil und abriebfest gestaltet werden. Es ist aber auch möglich, nur den Zugschnurkanal aus einem abriebfesten Kunststoff herzustellen oder den Zugschnurkanal mit einer Metalleinlage zu versehen.The decisive advantage of this transfer of the pull cord in a guide channel is that the pull cord no longer loads the deflection, whereby the deflection can be made of a very light and soft material. The coil, in particular the fixed cheek of the coil, can be made very stable and resistant to abrasion. But it is also possible to produce only the Zugschnurkanal of an abrasion-resistant plastic or to provide the Zugschnurkanal with a metal insert.
Ein weiterer Vorteil entsteht dadurch, dass die Zugschnur eine sichere Führung erhält, die unter keinen Umständen ein Aushängen der Zugschnur während des normalen Gebrauchs des Raffvorhangs ermöglicht. Trotzdem ist die Abnahme des Vorhangs völlig unproblematisch. Wenn der Vorhang vom Flauschband abgezogen wird, rutschen die Umlenkösen aus der Aufnahme heraus und nehmen dabei die Zugschnur wieder auf.Another advantage arises from the fact that the pull cord receives a secure guidance, under no circumstances a disconnecting the pull cord during normal use of the Roman shade. Nevertheless, the decrease of the curtain is completely unproblematic. When the curtain is removed from the loop tape, the deflection eyelets slip out of the receptacle, taking up the drawstring again.
Außerdem hat sich herausgestellt, dass der Vorhang bei der Montage an die Aufzugsvorrichtung eine exakte seitliche und höhenmäßige Ausrichtung erhält. Durch das Einführen der Ösen in die Aufnahme der feststehenden Wangen der Spulen bleibt ständig eine definierte Lage zwischen dem Vorhang, den darin geführten Zugschnüren und der Wickelvorrichtung erhalten und es entsteht eine sehr gute Zugentlastung des Vorhangs. Dadurch behält der gesamte Raffvorhang ständig einen guten Sitz.In addition, it has been found that the curtain receives an exact lateral and height alignment when mounted on the elevator device. By inserting the eyelets in the recording of the fixed cheeks of the coils remains a defined position between the curtain, the pull cords guided therein and the winding device is constantly maintained and there is a very good strain relief of the curtain. As a result, the entire Roman shade keeps a good seat.
Die Mitnehmerscheibe kann eine Aussparung besitzen, die in Richtung entgegengesetzt zur Aufwickelrichtung vertieft ist. Hier hinein verlagert sich die Zugschnur, sobald der Vorhang gerafft wird.The drive plate may have a recess which is recessed in the direction opposite to the Aufwickelrichtung. Here, the drawstring shifts as soon as the curtain is gathered.
Vorteilhaft für die Montage ist, wenn ein längliches Gehäuse vorgesehen ist, in dem die Wickelwelle mit den Spulen für alle U-förmig geführten Zugschnüre eingeordnet sind. Die Vorrichtung kann dann vor der Montage vollständig in das Gehäuse eingebaut werden. Das Gehäuse besitzt zweckmäßigerweise ein Innenprofil, in dem die Wangen arretiert werden und die Gleiter drehsicher gleiten können.Is advantageous for the assembly, if an elongated housing is provided, in which the winding shaft are arranged with the coils for all U-shaped pull cords. The device can then be completely installed in the housing prior to assembly. The housing has expediently an inner profile in which the cheeks are locked and the gliders can slide against rotation.
Die erfinderische Vorrichtung ist auch für Einzelschnüre einsetzbar, wenn nur eine Spule verwendet wird und die einzeln geführte Zugschnur an der Mitnehmerscheibe befestigt wird. Dieser Einsatz kann erforderlich werden, wenn durch eine bestimmte Musterung des Vorhangs eine ungerade Anzahl von Zugschnüren in vorliegt. Allerdings fällt dann der Vorteil der einfachen Montage und Demontage des Vorhangs weg.The inventive device can also be used for single cords, if only one coil is used and the individually guided pull cord is attached to the drive plate. This use may be required if an odd number of drawstrings are present in a particular pattern of the curtain. However, then falls the advantage of easy assembly and disassembly away from the curtain.
Der Vorhang, in dem die Zugschnüre U-förmig geführt sind, wird im entrafften Zustand montiert. Bei der Montage werden zunächst die Umlenkelemente in die Aufnahme der feststehenden Wangen der Spulen eingelegt. Gleichzeitig wird der Raffvorhang mittels Klettverbindung auf der Vorhangschiene befestigt. Dabei wird der parallel zur Wickelwelle verlaufende Teil der U-förmig geführten Zugschnur in die Führungen der Wangen, die Aussparungen der Gleiter und die Aussparungen der Mitnehmerscheibe eingelegt. Wird jetzt die Wickelwelle betätigt, drehen sich die Mitnehmerscheiben, der Zugschnurteil wird zwischen den beiden Mitnehmerscheiben mitgenommen und die Teile der Zugschnur zwischen den Mitnehmerscheiben und den Umlenkelementen werden an beiden Seiten aufgezogen. Gleichzeitig bewegen sich die Gleiter auf dem Gewinde der Spulenkörper jeweils in Richtung der Umlenkelemente. Die Zugschnüre werden dadurch beginnend an der Mitnehmerscheibe nebeneinander in das Gewinde des Spulenkörpers eingelegt.The curtain, in which the drawstrings are guided in a U-shape, is mounted in the unraveled state. During assembly, first the deflecting elements are inserted into the receptacle of the fixed cheeks of the coils. At the same time, the Roman shade is attached to the curtain rail by means of Velcro. In this case, the running parallel to the winding shaft part of the U-shaped pull cord is inserted into the guides of the cheeks, the recesses of the slider and the recesses of the drive plate. Now, when the winding shaft is actuated, the drive plates rotate, the Zugschnurteil is entrained between the two drive plates and the parts of the pull cord between the drive plates and the deflector are mounted on both sides. At the same time, the sliders move on the thread of the bobbin in each case in the direction of the deflection. The pull cords are thereby inserted next to each other in the thread of the bobbin, starting at the drive plate.
Der entscheidende Vorteil der Lösung liegt insbesondere darin, dass die Zugschnüre stets nebeneinander auf dem Spulenkörper aufgezogen werden, wobei die einfache Montage und Demontage des Vorhangs erhalten bleibt. Es wird dadurch das ungleichmäßige Aufziehen der einzelnen Zugschnüre mit den negativen Folgen des Verziehens des Vorhangs vermieden. Ein weiterer entscheidender Vorteil entsteht durch die gleichbleibende Kraft beim Raffen und Entraffen des Vorhangs. Die bei jedem Raffvorhang der bekannten Art vorhandene aufwendige Bremsvorrichtung an der Wickelwelle kann dadurch entfallen. Die Aufzugsvorrichtung wird dadurch zum einen sehr geräuscharm und zum anderen einfacher in der Konstruktion.The decisive advantage of the solution lies in the fact that the pull cords are always mounted side by side on the bobbin, whereby the simple assembly and disassembly of the curtain is maintained. It is thereby avoided the uneven fitting of the individual drawstrings with the negative consequences of warping the curtain. Another decisive advantage comes from the constant force when shirring and releasing the curtain. The costly braking device on the winding shaft, which is present in every Roman blind of the known type, can thereby be dispensed with. The elevator device is characterized on the one hand very quiet and on the other hand simpler in construction.
Ein weiterer sehr wesentliche Vorteil ergibt sich aus der Anordnung der Umlenkelemente direkt an der feststehenden Wange der Spule. Es ist immer gesichert, dass auch bei einer Änderung der Breite der Zugschnurführung im Vorhang die vorhandene Vorrichtung einsatzfähig bleibt. Es müssen lediglich die Spulen auf der Wickelwelle verschoben werden, so dass die feststehenden Wangen an den Umlenkelementen liegen.Another very significant advantage arises from the Arrangement of the deflection directly on the fixed cheek of the coil. It is always ensured that even with a change in the width of the pull cord guide in the curtain, the existing device remains operational. Only the coils on the winding shaft must be moved so that the fixed cheeks are located on the deflecting elements.
