Description

Die Erfindung betrifft eine Vorhangschienenanordnung.The invention relates to a curtain track assembly.

Vorhangschienen verfügen in der Regel über einen Laufkanal, in welchem ein Vorhang über im Laufkanal verschiebliche Gleiter aufgehängt werden kann. Es gibt eine Vielzahl von Vorhangschienensystemen, welche jedoch stets über einen oder eine Mehrzahl Halter an der Wand oder an der Decke befestigt werden. Je nach Last der Vorhänge biegen entsprechende Vorhangschienen infolge der Schwerkraft mehr oder weniger stark durch. Dies ist optisch nachteilig. Man kann dies dadurch beheben, dass man in kürzeren Abständen Halter installiert, was wiederum auch aus optischen Gründen nicht immer gewünscht ist. Es gibt inzwischen Systeme, die lediglich einen mittig angeordneten Halter aufweisen, wobei die Vorhangschiene mit beiden Hälften mehr oder weniger frei tragend zu beiden Seiten des Halters absteht. Diese freien Enden unterliegen natürlich auch der Last des Vorhangs, insbesondere wenn dieser zu einer Seite aufgezogen ist, sodass gerade die Enden die komplette Last tragen.Curtain rails usually have a running channel in which a curtain can be hung using sliders that can be moved in the running channel. There are a variety of curtain rail systems, but they are always attached to the wall or ceiling using one or more brackets. Depending on the load of the curtains, corresponding curtain rails bend more or less strongly as a result of gravity. This is optically disadvantageous. This can be remedied by installing holders at shorter intervals, which in turn is not always desirable for optical reasons. There are now systems that only have a centrally arranged holder, with the curtain rail protruding with both halves more or less self-supporting on both sides of the holder. Of course, these free ends are also subject to the load of the curtain, especially if it is pulled open to one side, so that the ends carry the entire load.

Aus EP 1 554 956 B1 ist ein System bekannt geworden, bei dem eine rohrförmige Gardinenstange eine Innenspanneinrichtung aufweist. Hierbei werden im Rohr geführte Spanndrähte, die an einer Seite zur Mitte der rohrförmigen Vorhangstange hin fest mit dieser verbunden sind und dort entlang der Mittellinie des Rohrs verlaufen, an den Enden der Vorhangstange durch Schrauben gespannt. An den Enden der Vorhangstange sind die Spanndrähte außerhalb der Mittellinie angeordnet, sodass sich eine Verlagerung des Rohrs ergibt, wenn man den Spanndraht spannt. Dadurch verbiegt sich das Rohr zur Decke hin und wirkt damit der durch den Vorhang auf die Vorhangstange ausgeübten Last entgegen. So können Durchbiegungen kompensiert werden.Out of EP 1 554 956 B1 a system has become known in which a tubular curtain rod has an internal tensioning device. In this case, tension wires guided in the tube, which are firmly connected to the tubular curtain rod on one side towards the center of the latter and run there along the center line of the tube, are tensioned at the ends of the curtain rod by screws. At the ends of the curtain rod, the tension wires are arranged outside the center line, so that there is a displacement of the pipe when the tensioning wire is tightened. This causes the tube to bend toward the ceiling, counteracting the load exerted by the curtain on the curtain rod. In this way, deflections can be compensated.

Die genannte Technik setzt allerdings eine mehr oder weniger rohrförmige Gardinenstange voraus.However, the technique mentioned requires a more or less tubular curtain rod.

Aus DE 20 2017 102 916 U1 ist eine Vorhangschienenanordnung nach dem Oberbegriff des Anspruchs 1 bekannt.Out of DE 20 2017 102 916 U1 a curtain track assembly according to the preamble of claim 1 is known.

Aufgabe der vorliegenden Erfindung ist es, eine Vorhangschienenanordnung mit der Möglichkeit, eine Durchbiegung auszugleichen, anzugeben, die sich für alle gängigen Vorhangschienen eignet.The object of the present invention is to specify a curtain rail arrangement with the option of compensating for sagging, which is suitable for all common curtain rails.

Gelöst wird diese Aufgabe durch eine Vorhangschienenanordnung mit den Merkmalen des Anspruchs 1. Vorteilhafte Ausführungsformen finden sich in den Unteransprüchen.This problem is solved by a curtain rail arrangement with the features of claim 1. Advantageous embodiments can be found in the dependent claims.

Die erfindungsgemäße Vorhangschienenanordnung nutzt als Spannmittel wenigstens ein drehbares Element, dessen Drehung eine Durchbiegung der Vorhangschiene bewirkt. Dadurch, dass die Drehachse des Spannmittels näher an der Oberseite der Vorhangschienenanordnung liegt als an deren Unterseite, bewirkt das Spannen des Spannmittels eine Verbiegung der Vorhangschienenanordnung nach oben zur Decke hin. Durch diese Verbiegung kann eine durch die Gewichtskraft des an der Vorhangschiene aufgehängten Vorhangs hervorgerufene Verbiegung kompensiert werden.The curtain rail arrangement according to the invention uses at least one rotatable element as a tensioning means, the rotation of which causes the curtain rail to sag. Due to the fact that the axis of rotation of the tensioning means is closer to the top of the curtain rail assembly than to the bottom thereof, the tensioning of the tensioning means causes the curtain rail assembly to bend upwards towards the ceiling. This bending can by the weight of the Curtain rail hung curtain caused deflection are compensated.

Die erfindungsgemäße Vorhangschienenanordnung weist hierzu einen sich in einer Hauptlängserstreckungsrichtung erstreckenden Vorhangschienenkörper auf, welcher zumindest einen Laufkanal umfasst, der zur Aufnahme von Vorhanggleitern ausgebildet ist. Dabei kann die Vorhangschienenanordnung mit einer Halterung zur Befestigung der Vorhangschienenanordnung an einer Wand oder Decke verbunden werden. Die bestimmungsgemäß aufgehängte Vorhangschienenanordnung weist dabei eine zur Decke hin ausgerichtete Oberseite und eine zum Boden hin ausgerichtete Unterseite auf.For this purpose, the curtain rail arrangement according to the invention has a curtain rail body which extends in a main longitudinal extension direction and comprises at least one running channel which is designed to accommodate curtain gliders. The curtain rail assembly can be connected to a bracket for attaching the curtain rail assembly to a wall or ceiling. The curtain rail arrangement which is hung as intended has an upper side which is aligned towards the ceiling and an underside which is aligned towards the floor.

Zur Krafteinleitung einer die Verbiegung des Vorhangschienenkörpers bewirkenden Spannkraft sind in der erfindungsgemäßen Vorhangschienenanordnung zwei Gegenlagerbereiche vorgesehen, welche mit dem Vorhangschienenkörper verschiebefest verbunden oder verbindbar sind. Verschiebefest meint in diesem Zusammenhang, dass beim Spannen der erfindungsgemäßen Vorrichtung die Gegenlagerbereiche sich entlang der Hauptlängserstreckungsrichtung des Vorhangschienenkörpers nicht verschieben können. Auf diese Weise kann eine in die Gegenlagerbereiche eingeleitete Kraft zur Verbiegung des Vorhangschienenkörpers genutzt werden.For the introduction of a tensioning force causing the bending of the curtain rail body, two abutment areas are provided in the curtain rail arrangement according to the invention, which are connected or can be connected to the curtain rail body in a non-displaceable manner. In this context, non-displaceable means that when the device according to the invention is tensioned, the counter-bearing areas cannot be displaced along the main longitudinal direction of extent of the curtain rail body. In this way, a force introduced into the counter-bearing areas can be used to bend the curtain rail body.

Zum Biegen der Vorhangschiene verfügt die erfindungsgemäße Vorhangschienenanordnung über eine Spanneinrichtung, die wenigstens ein Spannmittel und eine Aufnahmeeinrichtung aufweist, an der das Spannmittel aufgenommen ist. Dabei ist das wenigstens eine Spannmittel in wenigstens einem der Gegenlagerbereiche im Wesentlichen parallel zur Hauptlängserstreckungsrichtung drehbar angeordnet. Das Spannmittel ist mit dem Aufnahmeabschnitt drehbar verbunden, wobei die Drehachse des wenigstens einen Spannmittels zur Oberseite des Vorhangschienenkörpers einen geringeren Abstand aufweist als zu dessen Unterseite. Der Aufnahmeabschnitt kann dabei zwischen den Gegenlagerbereichen oder auch in einem gegenüberliegenden Gegenlagerbereich angeordnet sein und ist selbst mit einem Abschnitt des Vorhangschienenkörpers mittelbar oder unmittelbar verbunden bzw. gekoppelt. Die Kopplung kann beispielsweise auch über einen Gegenlagerbereich erfolgen, die ja selbst an dem Vorhangschienenkörper fixiert sind. Das wenigstens eine Spannmittel weist, insbesondere im Bereich der Stirnseite des zugehörigen Gegenlagerbereiches, ein drehbar gelagertes Drehelement auf, welches sich an einer am Gegenlagerbereich angeordneten Stützfläche abstützt.In order to bend the curtain rail, the curtain rail arrangement according to the invention has a tensioning device which has at least one tensioning device and a receiving device on which the tensioning device is received. While that is at least one clamping means is arranged in at least one of the counter-bearing areas so as to be rotatable essentially parallel to the main direction of longitudinal extension. The tensioning means is rotatably connected to the receiving section, with the axis of rotation of the at least one tensioning means being at a smaller distance from the upper side of the curtain rail body than from its underside. The receiving section can be arranged between the counter-bearing areas or also in an opposite counter-bearing area and is itself directly or indirectly connected or coupled to a section of the curtain rail body. The coupling can, for example, also take place via a counter bearing area which is itself fixed to the curtain rail body. The at least one clamping means has, in particular in the area of the end face of the associated counter-bearing area, a rotatably mounted rotary element which is supported on a support surface arranged on the counter-bearing area.

Erfindungsgemäß ist zwischen den Gegenlagerbereichen ein Mittelabschnitt angeordnet. Dieser ist zur Versteifung des Vorhangschienenkörpers ausgebildet und mit diesem verbunden. Dabei kann der Aufnahmeabschnitt durch den Mittelabschnitt geführt sein und sich beispielsweise über die gesamte Länge des Mittelabschnitts erstrecken. Durch die Versteifung des Vorhangschienenkörpers wird erreicht, dass beim Spannen der Spanneinrichtung die in den Vorhangschienenkörper eingeleitete Biegekraft tatsächlich nur eine Biegung der Vorhangschiene in eine bevorzugte Richtung, nämlich nach oben zur Decke hin und nicht in andere Richtungen, bewirkt.According to the invention, a middle section is arranged between the counter-bearing areas. This is designed to stiffen the curtain rail body and is connected to it. The receiving section can be guided through the middle section and can extend, for example, over the entire length of the middle section. The stiffening of the curtain rail body ensures that when the tensioning device is tightened, the bending force introduced into the curtain rail body actually only causes the curtain rail to bend in a preferred direction, namely upwards towards the ceiling and not in other directions.

Nach einer vorteilhaften Ausführungsform der vorliegenden Erfindung ist vorgesehen, dass in beiden Gegenlagerbereichen im Wesentlichen parallel zur Hauptlängserstreckungsrichtung drehbar angeordnete Spannmittel anordnet sind, welche mit dem dann zwischen den Gegenlagerbereichen angeordneten Aufnahmeabschnitt drehbar verbunden sind. Die Drehachsen der Spannmittel weisen zur Oberseite des Vorhangschienenkörpers einen geringeren Abstand auf als zu dessen Unterseite (U), wobei die Spannmittel jeweils, insbesondere im Bereich der Stirnseiten der Gegenlagerbereiche, drehbar gelagerte Drehelemente aufweisen, die sich jeweils an einer am Gegenlagerbereich angeordneten Stützfläche abstützen.According to an advantageous embodiment of the present invention, it is provided that in both counter-bearing areas rotatable clamping means are arranged essentially parallel to the main longitudinal extension direction, which are rotatably connected to the receiving section then arranged between the counter-bearing areas. The axes of rotation of the clamping means are at a smaller distance from the upper side of the curtain rail body than from its underside (U), with the clamping means each having rotatably mounted rotary elements, particularly in the area of the end faces of the counter-bearing areas, which are each supported on a support surface arranged on the counter-bearing area.

Bevorzugt ist dabei vorgesehen, dass der Aufnahmeabschnitt lediglich in einem Bereich mit dem Vorhangschienenkörper verschiebefest verbunden ist, welcher sich entfernt von den in Hauptlängserstreckungsrichtung liegenden Enden des Aufnahmeabschnitts, insbesondere etwa mittig am Aufnahmeabschnitt, befindet. Beim Spannen der erfindungsgemäßen Spannvorrichtung wird so eine Zugkraft zwischen dem Befestigungsbereich des Gegenlagerbereichs und dem Befestigungsbereich des Aufnahmeabschnitts in den Vorhangschienenkörper eingeleitet. Da das Spannmittel und der Aufnahmeabschnitt näher zur Oberseite der Vorhangschienenanordnung als zur Unterseite angeordnet sind, wird durch diese Zugkraft eine Krümmung oder Biegung des Vorhangschienenkörpers zwischen den Befestigungsbereichen erzeugt.Provision is preferably made here for the receiving section to be non-displaceably connected to the curtain rail body only in a region which is remote from the ends of the receiving section in the main longitudinal direction, in particular approximately centrally on the receiving section. When tensioning the tensioning device according to the invention, a tensile force is introduced into the curtain rail body between the fastening area of the counter bearing area and the fastening area of the receiving section. Since the tensioning means and the receiving portion are located closer to the top of the curtain rail assembly than to the bottom, this tensile force creates a curvature or bend in the curtain rail body between the attachment portions.

Die Spannmittel weisen bevorzugt zumindest an dem von den Drehelementen entfernt liegenden Enden ein Gewinde auf, welches an einem Gegengewinde des Aufnahmeabschnitts aufgenommen ist. Da Spannmittel und Aufnahmeabschnitt zwischen deren Befestigungsbereichen am Vorhangschienenkörper ein zugstangenartiges Zugmittel bilden, wird beim Spannen des Spannmittels die Länge dieses Zugmittels verkürzt und sorgt so für eine Krafteinleitung in den Vorhangschienenkörper und somit für dessen Verbiegung.The clamping means preferably have a thread at least on the ends remote from the rotating elements is accommodated on a mating thread of the receiving section. Since the tensioning means and receiving section form a pull rod-like traction means between their fastening areas on the curtain rail body, the length of this traction means is shortened when the tensioning means is tightened and thus ensures that force is introduced into the curtain rail body and thus causes it to bend.

Die Vorhangschienenanordnung kann eine Frontblende aufweisen, die insbesondere mit dem Vorhangschienenkörper, insbesondere mit dessen Laufkanal, verbunden oder einstückig ausgebildet ist.The curtain rail arrangement can have a front panel which is connected in particular to the curtain rail body, in particular to its running channel, or is formed in one piece.

Bevorzugt kann der Vorhangschienenkörper aus einem Profil, insbesondere einem Metallprofil, bevorzugt einem Aluminiumprofil, gebildet werden.The curtain rail body can preferably be formed from a profile, in particular a metal profile, preferably an aluminum profile.

Bevorzugt ist der Aufnahmeabschnitt eine Stange mit Gewinden, insbesondere Innengewinden an beiden Enden. Das durch die Stange und die Spannmittel gebildete Zugmittel kann so auf einfache Weise durch Drehen des Spannmittels verkürzt werden und für die Biegung der Vorhangschiene sorgen.The receiving section is preferably a rod with threads, in particular internal threads, on both ends. The traction means formed by the rod and the tensioning means can thus be shortened in a simple manner by turning the tensioning means and ensure the bending of the curtain rail.

Bevorzugt können auch die Gegenlagerbereiche mit Versteifungen ausgestattet sein. Nach einer bevorzugten Ausführungsform kann vorgesehen sein, dass der Mittelabschnitt und/oder die Gegenlagerbereiche als Winkelprofil(e) ausgebildet ist/sind. Hierdurch lässt sich eine besonders gute Versteifung des Vorhangschienenkörpers erreichen. Dabei kann bevorzugt vorgesehen sein, dass das oder die Winkelprofil (e) einen im bestimmungsgemäßen Gebrauch der Vorhangschienenanordnung im Wesentlichen horizontal orientierten Schenkel und einen im Wesentlichen vertikal orientierten Schenkel aufweist/aufweisen.Preferably, the counter-bearing areas can also be equipped with reinforcements. According to a preferred embodiment, it can be provided that the middle section and/or the counter-bearing areas is/are designed as angle profile(s). In this way, a particularly good stiffening of the curtain rail body can be achieved. It can preferably be provided that the one or more angle profile (s). in the intended use of the curtain rail arrangement has/have essentially horizontally oriented legs and one essentially vertically oriented leg.

Für die Verbindung der zur Versteifung ausgebildeten Gegenlagerbereiche bzw. des Mittelabschnitts am Vorhangschienenkörper gibt es zahlreiche Möglichkeiten. Eine bevorzugte Ausführungsform sieht vor, dass der Mittelabschnitt und/oder die Gegenlagerbereiche auf den Vorhangschienenkörper aufgesteckt oder aufgeschoben sind. Dazu kann der Vorhangschienenkörper entsprechende Rippen oder Vorsprünge aufweisen, die mit entsprechenden Aussparungen oder Vorsprüngen am Mittelabschnitt bzw. den Gegenlagerbereichen zusammengreifen, wodurch ein Formschluss entsteht, der allerdings mit einem gewissen Spiel behaftet sein kann.There are numerous possibilities for connecting the abutment areas designed for reinforcement or the middle section on the curtain rail body. A preferred embodiment provides that the central section and/or the counter-bearing areas are plugged or pushed onto the curtain rail body. For this purpose, the curtain rail body can have corresponding ribs or projections which engage with corresponding recesses or projections on the central section or the counter-bearing areas, resulting in a form fit which, however, can be subject to a certain amount of play.

Nach einer weiteren Ausführungsform der vorliegenden Erfindung kann vorgesehen sein, dass der Mittelabschnitt und/oder die Gegenlagerbereiche durch wenigstens eine kraftschlüssige Verbindung, insbesondere durch eine Schraube, mit dem Vorhangschienenkörper verbunden sind. Hier bieten sich vor allem einschraubbare Gewindestifte oder dergleichen an, welche durch die Gegenlagerbereiche oder den Mittelabschnitt geführt sind und in einem Gewinde des Vorhangschienenkörpers aufgenommen sind oder gegen eine Fläche des Vorhangschienenkörpers drücken.According to a further embodiment of the present invention, it can be provided that the middle section and/or the abutment areas are connected to the curtain rail body by at least one non-positive connection, in particular by a screw. Threaded pins or the like that can be screwed in are particularly suitable here, which are guided through the counter-bearing areas or the middle section and are received in a thread of the curtain rail body or press against a surface of the curtain rail body.

Weiter kann vorgesehen sein, dass der Mittelabschnitt die Gegenlagerbereiche durch wenigstens eine kraftschlüssige Verbindung in einem dem Mittelabschnitt oder dem Aufnahmeabschnitt benachbarten Bereich mit dem Vorhangschienenkörper verbunden sind. Verlagert man diese Verbindung in die Nähe des Aufnahmeabschnitts, so werden die Enden der Vorhangschiene beim Spannen der Spanneinrichtung zwar angehoben, werden allerdings nicht mit gekrümmt, sondern bleiben zwischen der kraftschlüssigen Verbindung und dem jeweiligen Ende des Vorhangschienenkörpers gerade.It can further be provided that the middle section, the counter bearing areas by at least one non-positive connection are connected to the curtain rail body in an area adjacent to the central portion or the receiving portion. If this connection is shifted close to the receiving section, the ends of the curtain rail are lifted when the tensioning device is tightened, but are not curved as well, but remain straight between the non-positive connection and the respective end of the curtain rail body.

Die in Figur 1 gezeigte Vorhangschienenanordnung 1 weist einen Vorhangschienenkörper 10 auf und ist üblicherweise mit einem Halter (nicht gezeigt) verbunden, welcher an einer Wand oder Decke (nicht gezeigt) befestigt werden kann. Der Halter wird an der Vorhangschienenanordnung 1 bevorzugt mittig angebracht, so dass sich die Vorhangschienenanordnung 1 in ihrer Hauptlängserstreckungsrichtung X zu beiden Seiten des Halters erstreckt.In the figure 1 The curtain track assembly 1 shown has a curtain track body 10 and is typically connected to a bracket (not shown) which can be secured to a wall or ceiling (not shown). The holder is preferably attached centrally to the curtain rail arrangement 1, so that the curtain rail arrangement 1 extends in its main longitudinal direction X on both sides of the holder.

Der Vorhangschienenkörper 10 weist einen Laufkanal 11 auf, in dem Gleiter von Vorhängen eingehängt werden können. Üblicherweise findet sich auch an der Vorderseite des Vorhangschienenkörpers 10 eine Blende 80 (vergleiche die Figuren 3A und 3B), welche dazu ausgelegt ist, den Laufkanal 11 zu verdecken, sodass man dort eingehängte Gleiter von vorne nicht sieht. Der Vorhangschienenkörper 10 ist ein längliches Gebilde und erstreckt sich in einer Hauptlängserstreckungsrichtung X. Üblicherweise werden solche Vorhangschienenkörper 10 aus Metallprofilen, insbesondere Aluminiumprofilen, oder auch Kunststoffprofilen hergestellt. Die Oberseite O ist diejenige Seite, die im bestimmungsgemäßen Gebrauch der erfindungsgemäßen Vorhangschienenanordnung 1 zur Decke hin weist, während die Unterseite U diejenige Seite ist, die beim bestimmungsgemäßen Gebrauch der Vorhangschienenanordnung 1 zum Boden hin weist.The curtain rail body 10 has a running channel 11 in which sliders of curtains can be hung. Usually there is also a panel 80 on the front side of the curtain rail body 10 (compare Figs Figures 3A and 3B ), which is designed to cover the running channel 11 so that you cannot see the sliders that are attached there from the front. The curtain rail body 10 is an elongate structure and extends in a main longitudinal direction X. Such curtain rail bodies 10 are usually made of metal profiles, in particular aluminum profiles, or also plastic profiles. The top O is the side that faces the ceiling in the intended use of the curtain rail assembly 1 according to the invention, while the bottom U is the side that when the curtain rail assembly 1 is used as intended, faces the floor.

Die Bezugszeichen 20 und 30 bezeichnen zwei Gegenlagerbereiche, welche beim Spannen der Vorhangschienenanordnung entstehende Kräfte in den Vorhangschienenkörper einleiten können und daher an dem Vorhangschienenkörper 10 so angebracht sind, dass sie zumindest beim Spannen nicht in Richtung X verschoben werden können. Die Gegenlagerbereiche 20, 30 bilden mithin einen Teil der Spanneinrichtung der erfindungsgemäßen Vorhangschienenanordnung 1. Die verschiebefeste Fixierung erfolgt bevorzugt etwa durch Gewindestifte oder Schrauben, hier mit 24 bzw. 34 angedeutet. Die Gegenlagerbereiche 20, 30 befinden sich im gezeigten Beispiel beidseitig eines Mittelabschnitts 70, auf dessen Ausgestaltung im Zusammenhang mit den nachfolgenden Figuren noch weiter eingegangen wird. Die Fixierung der Gegenlagerbereiche 20, 30 erfolgt bevorzugt in der Nähe des Mittelabschnitts 70.Reference numerals 20 and 30 designate two counter-bearing areas which can introduce forces into the curtain rail body when the curtain rail arrangement is tensioned and are therefore attached to the curtain rail body 10 in such a way that they cannot be displaced in the X direction, at least when tensioned. The abutment areas 20, 30 thus form part of the tensioning device of the curtain rail arrangement 1 according to the invention. In the example shown, the abutment areas 20, 30 are located on both sides of a middle section 70, the configuration of which will be discussed in more detail in connection with the following figures. The counter bearing areas 20, 30 are preferably fixed in the vicinity of the middle section 70.

Im Bereich dieses Mittelabschnitts 70 ist ein hier beispielhaft als Stange angedeuteter Aufnahmeabschnitt 40 dargestellt, der einen weiteren Teil der erfindungsgemäßen Spanneinrichtung bildet und bevorzugt Gewindelöcher aufweist, in die entsprechende, in den Gegenlagerbereichen 20 bzw. 30 geführte Spannmittel 22 bzw. 32 eingesetzt oder geführt sind. Es ist auch möglich, lediglich ein einziges Spannmittel zu verwenden, und dieses in einen Aufnahmeabschnitt 40 in der Mitte oder am jeweils gegenüberliegenden Gegenlagerbereich 20, 30 einzuschrauben. Die weitere Beschreibung gilt daher, sofern auf jeweils zwei Spannmittel 22 bzw. 32 abgestellt wird, genauso für das Vorhandensein lediglich eines einzigen Spannmittels. Die Spannmittel 22, 32 und der Aufnahmeabschnitt bilden ein Zugmittel, dessen Belastung auf Zug dazu führt, dass sich der Vorhangschienenkörper 10 biegt. Der Aufnahmeabschnitt 40 ist auf dem Vorhangschienenkörper 10 bevorzugt ebenfalls befestigt, bevorzugt etwa mittig, wie beispielsweise durch die Befestigungen 73, bei denen es sich auch um Schrauben der Gewindestifte handeln kann, angedeutet. Der Aufnahmeabschnitt 40 muss aber nicht mit der Vorhangschiene verbunden werden, eine mittelbare Kopplung mit der Vorhangschiene, beispielsweise über einen der Gegenlagerbereiche 20, 30 genügt ebenfalls, da dann die Krafteinleitung über die Fixierung 24 bzw. 34 in den Vorhangschienenkörper 10 erfolgt.In the area of this middle section 70, a receiving section 40, indicated here by way of example as a rod, is shown, which forms a further part of the clamping device according to the invention and preferably has threaded holes into which corresponding clamping means 22 or 32 guided in the counter-bearing areas 20 or 30 are inserted or guided . It is also possible to use only a single clamping means and to screw this into a receiving section 40 in the middle or on the opposite counter-bearing area 20, 30 in each case. The further description therefore applies if two clamping means 22 or 32 are used is, just as for the presence of only a single clamping device. The tensioning means 22, 32 and the receiving section form a traction means whose tensile loading causes the curtain rail body 10 to bend. The receiving section 40 is preferably also attached to the curtain rail body 10, preferably approximately centrally, as indicated, for example, by the attachments 73, which can also be screws of the threaded pins. However, the receiving section 40 does not have to be connected to the curtain rail; an indirect coupling to the curtain rail, for example via one of the abutment areas 20, 30, is also sufficient, since the force is then introduced via the fixation 24 or 34 into the curtain rail body 10.

An den Stirnseiten der Gegenlagerbereiche 20 bzw. 30 sind diese Spannmittel 22 bzw. 32 mit Drehelementen 21 bzw. 31 verbunden, mit denen die Spannmittel 22 bzw. 32 von außen etwa durch Ansetzen eines Werkzeugs W oder dergleichen in den Gegenlagerbereichen um eine, insbesondere zur Hauptlängserstreckungsrichtung X parallele, Drehachse A gedreht werden können. Im gezeigten Beispiel weist das Drehelement 21 beispielsweise eine Innensechskant-Vertiefung auf.On the end faces of the counter-bearing areas 20 and 30, these clamping devices 22 and 32 are connected to rotating elements 21 and 31, with which the clamping devices 22 and 32 can be rotated from the outside, for example by applying a tool W or the like in the counter-bearing areas around a, in particular for Main longitudinal direction X parallel, axis of rotation A can be rotated. In the example shown, the rotating element 21 has, for example, a hexagon socket recess.

Die Spannfunktion der erfindungsgemäßen Spanneinrichtung wird nachfolgend anhand der Figuren 2A bis 2C näher erläutert. Darin sind Längsschnitte durch die erfindungsgemäße Vorhangschienenanordnung in ihren Endbereichen und in ihrem Mittelbereich dargestellt.The clamping function of the clamping device according to the invention is based on the Figures 2A to 2C explained in more detail. It shows longitudinal sections through the curtain rail arrangement according to the invention in its end areas and in its middle area.

Man erkennt in Figuren 2A und 2B, dass das Spannmittel 22 bzw. 32 in die Enden der hier als Stange ausgebildeten Aufnahmeeinrichtung 40 in dortige Gewindelöcher 41 bzw. 42 eingeschraubt sind. Am jeweils anderen Ende der Spannmittel befindet sich Drehelemente 21 bzw. 31, welche sich an einer Stützfläche 23 bzw. 33 abstützen und mit welchen die Spannmittel 22 bzw. 32 gedreht werden können. Beim Drehen der Spannmittel 22 bzw. 32 bewegt sich dieses also beim Spannen parallel zur Hauptlängserstreckungsrichtung X in den Aufnahmeabschnitt 40 hinein, die fest mit den Spannmitteln 22 bzw. 32 verbundenen Drehelemente 21 bzw. 31 werden aber aufgrund der Stützflächen 23 bzw. 33 zurückgehalten, sodass sich zwischen den Befestigungen 24 bzw. 34 einerseits und der Befestigung 73 des Aufnahmeabschnitts 40 (vergleiche Figur 2C) andererseits eine Zugkraft aufbaut. Diese bewirkt, dass zwischen dem Bereich 73 und 24 einerseits und dem Bereich 73 und 34 andererseits eine Biegung der Vorhangschienenanordnung 1, insbesondere des Vorhangschienenkörpers 10, entsteht. Diese ist in Figur 2C durch die gestrichelte Linie und die Auf-wärtspfeile in den Figuren 2A, 2B angedeutet. Es erfolgt eine Aufwärtsbewegung, weil die Spannmittel 22 bzw. 32 einerseits und die Stange 40 andererseits außermittig, nämlich mit einem geringeren Abstand zur Oberseite O als zu Unterseite U angeordnet sind.One recognizes in Figures 2A and 2B that the clamping means 22 or 32 are screwed into the ends of the receiving device 40 embodied here as a rod in threaded holes 41 or 42 there. At the respective other end of the clamping means are rotating elements 21 or 31, which are supported on a support surface 23 or 33 and with which the clamping means 22 or 32 can be rotated. When the clamping means 22 or 32 is rotated, it moves parallel to the main longitudinal extension direction X into the receiving section 40 during clamping, but the rotating elements 21 or 31, which are firmly connected to the clamping means 22 or 32, are held back by the support surfaces 23 or 33, respectively. so that between the attachments 24 and 34 on the one hand and the attachment 73 of the receiving section 40 (cf Figure 2C ) on the other hand builds up a tensile force. This causes the curtain rail arrangement 1, in particular the curtain rail body 10, to bend between the area 73 and 24 on the one hand and the area 73 and 34 on the other hand. This is in Figure 2C by the dashed line and the up arrows in the Figures 2A, 2B implied. There is an upward movement because the clamping means 22 or 32 on the one hand and the rod 40 on the other hand are arranged eccentrically, namely at a smaller distance from the upper side O than from the lower side U.

Aufgrund der benachbart zum Aufnahmeabschnitt 40 angeordneten Fixierung 24 bzw. 34 der Gegenlagerbereiche 20 bzw. 30 am Vorhangschienenkörper 10, wird hier nur der Bereich ab der Fixierung zum Aufnahmeabschnitt hin gekrümmt, die weiter außen liegenden Bereiche zwischen der Fixierung 24 bzw. 34 und den jeweiligen freien Enden des Vorhangschienenkörpers 10 bleiben im Wesentlichen gerade.Due to the fixation 24 or 34 of the counter bearing areas 20 or 30 on the curtain rail body 10 arranged adjacent to the receiving section 40, only the area from the fixation to the receiving section is curved here, the areas lying further outside between the fixation 24 or 34 and the respective free ends of the curtain rail body 10 remain substantially straight.

Das Spannen des Vorhangschienenkörpers 10 würde normalerweise natürlich auch dazu führen, dass nicht nur eine Verbiegung des Vorhangschienenkörpers 10 nach oben erfolgt, sondern beispielsweise auch nach hinten eine Krümmung eintreten kann. Folglich ist es zweckmäßig, den Vorhangschienenkörper 10 zu versteifen, bzw. die Krümmung in eine andere Richtung als die Richtung nach oben einzuschränken. Aus den Schnittansichten der Figur 3A und 3B ist erkennbar, wie man dies lösen kann.The tensioning of the curtain rail body 10 would of course normally also result in the curtain rail body 10 not only being bent upwards, but also, for example, curved backwards. Accordingly, it is effective to stiffen the curtain rail body 10, or to restrict the curvature in a direction other than the upward direction. From the sectional views of Figure 3A and 3B it is clear how to solve this.

Figur 3A zeigt dies für den einen Gegenlagerbereich 20, die Beschreibung für den zweiten Gegenlagerbereich 30 erübrigt sich aus Analogiegründen. Der Gegenlagerbereich 20 ist im gezeigten Beispiel als Winkelprofil ausgebildet, und weist einen im Wesentlichen horizontalen Schenkel 26 sowie einen im Wesentlichen vertikalen Schenkel 25 auf. Dadurch wird das so gebildete Profil verhältnismäßig biegesteif, vor allem auch, weil die Wandstärke des Winkelprofil deutlich größer ist als diejenige des Vorhangschienenkörpers 10. Wie man weiter erkennt, ist der Vorhangschienenkörper 10 so ausgebildet, insbesondere durch eine C-profilartige Form, dass er einen Abschnitt 28 des Gegenlagerbereichs 20 umgreift. Dabei ist ein Schenkel 12 der Vorhangschienenanordnung mit einem Steg versehen, der in eine entsprechende Aussparung 27 im Gegenlagerbereich eingreift. Diese Anordnung ermöglicht, dass der Gegenlagerbereich auf den Vorhangschienenkörper 10 aufgeschoben oder aufgesteckt werden kann. Man erkennt zudem, dass an einem Abschnitt 13 des Vorhangschienenkörpers 10 die Fixierung 24, insbesondere ein Gewindestift, angreift und den Gegenlagerbereich 20 am Vorhangschienenkörper 10 fixiert. Der Abschnitt 13 ist im gezeigten Beispiel gleichzeitig der Boden des Laufkanals 10. Ebenfalls erkennt man auf der Vorderseite die Blende 80, mit der die Einsichtsmöglichkeit in den Laufkanal 11 weitgehend vermieden wird. Figure 3A shows this for a counter-bearing area 20, the description for the second counter-bearing area 30 is superfluous for reasons of analogy. In the example shown, the abutment area 20 is designed as an angle profile and has a substantially horizontal leg 26 and a substantially vertical leg 25 . As a result, the profile formed in this way is relatively rigid, especially because the wall thickness of the angle profile is significantly greater than that of the curtain rail body 10. As can also be seen, the curtain rail body 10 is designed in such a way, in particular with a C-profile-like shape, that it has a Section 28 of the counter bearing area 20 encompasses. One leg 12 of the curtain rail arrangement is provided with a web which engages in a corresponding recess 27 in the counter bearing area. This arrangement allows the counter bearing area to be slid or clipped onto the curtain rail body 10 . One recognises In addition, the fixation 24 , in particular a threaded pin, acts on a section 13 of the curtain rail body 10 and fixes the abutment area 20 on the curtain rail body 10 . In the example shown, the section 13 is at the same time the bottom of the barrel channel 10. The screen 80 can also be seen on the front side, with which the possibility of looking into the barrel channel 11 is largely avoided.

Auch im mittleren Bereich der erfindungsgemäßen Vorhangschienenanordnung ist ein verstärkender Mittelabschnitt 70 angeordnet, der im Ausführungsbeispiel wiederum als Winkelprofil ausgebildet ist, welches einen etwa horizontalen Schenkel 71 bzw. einen vertikalen Schenkel 72 aufweist. Auch die übrige Ausgestaltung gleicht derjenigen, die in Figur 3A gezeigt ist. Hier bezeichnet das Bezugszeichen 74 die Aussparung, in die ein Schenkel 12 des Vorhangschienenkörpers 10 eingreift. Auch hier umgreift der Vorhangschienenkörper 10 wieder einen Abschnitt 75 des als Winkelprofil ausgebildeten Mittelabschnitts 70. Man erkennt hier ebenso den Aufnahmeabschnitt 40, der mittels eines Befestigungsmittels 73 relativ zum Vorhangschienenkörper 10 verschiebefest fixiert ist. Bevorzugt ist hier eine Schraube durch den Aufnahmeabschnitt 40 durch und in den Abschnitt 13 des Vorhangschienenkörpers 10 eingeschraubt.Also in the central area of the curtain rail arrangement according to the invention there is a reinforcing central section 70 which in the exemplary embodiment is in turn designed as an angle profile which has an approximately horizontal leg 71 or a vertical leg 72 . The rest of the design is also the same as that in Figure 3A is shown. Here, the reference number 74 designates the recess into which a leg 12 of the curtain rail body 10 engages. Here, too, the curtain rail body 10 again encompasses a section 75 of the central section 70 designed as an angle profile. Here, a screw is preferably screwed through the receiving section 40 and into the section 13 of the curtain rail body 10 .
