- the plate is advantageously around the lamellar edges, also called Lamellenbördel, pulled around and fixed. Because the lamellar edges can be stiffened by in particular also right-angled bending of the edge.
- the lamellae can not be stacked in the correct position, because instead of the lamellar flanges, the thickening of the guide lugs at the end of the guide member shaft lie on each other. Thus, there are gaps between two lamellar flanging of adjacent lamellae, so that the lamellae are not supported and the weight load is transmitted to the guide link shafts.
- the slats are not provided at both ends with guide members, but for example only mutually at one fin end and at the adjacent next slat only at the opposite end, so that between three slats, the middle slat one guide member at the right end of the lamella and the other two lamellae each receive a guide member on the left end of the lamella. From this mutually one-sided assembly of slats with guide members results in the prior art, a thinner but unstable and wind-prone Storenmontage and inevitably a corresponding damage susceptible Storen compassion.
- the US 2,770,296 A relates to guide members for a slat blind.
- the guide member in this case comprises a fastening element and a shaft, wherein the end of the shaft is followed by a partially recessed disc, which is suitable for engagement in a side guide rail. Slices of stacked lamellae are guided laterally through the shaft one above the other.
- the EP 0 616 108 A1 also relates to a slat blind, wherein a guide pin is provided at the ends of the slats, at the end of which a slider adjoins.

Description
Die Erfindung betrifft ein Führungsglied für einen Rafflamellenstore sowie einen Rafflamellenstore mit entsprechenden Führungsgliedern.The invention relates to a guide member for a Rafflamellenstore and a Rafflamellenstore with corresponding guide members.
Führungsglieder für Rafflamellenstoren sind beispielsweise aus der
Es ist auch nachteilig, dass unterschiedliche Führungsglieder für linke und rechte Enden von Storenlamellen bereitgehalten werden müssen. Werden gleichartige Elemente des Standes der Technik für das rechte und das linke Ende eines Storen verwendet, so hat der Zapfen oder die Endfläche bezüglich der Hauptachse der Lamelle rotationssymmetrisch zu sein, was den in einer Seitenführung eingeführten Flansch das Führungsgliedes noch einmal dicker macht, um ein sicheres Führen in diesen seitlichen Führungsschienen zu gewährleisten.It is also disadvantageous that different guide members must be kept ready for left and right ends of blind slats. If similar prior art elements are used for the right and left ends of a blind, the pin or end face must be rotationally symmetric with respect to the major axis of the sipe, making the guide member thicker in the guide once again to ensure safe guidance in these lateral guide rails.
Eine Möglichkeit des Standes der Technik in diesem Zusammenhang liegt darin, nur jeweils ein seitliches Ende einer Lamelle eines Rafflamellenstores mit einem Führungsglied verwendet wird, so dass sich bei einem Blick von vorne auf die Lamelle und das Führungsglied eine Abfolge der Führungsglieder rechts-links-rechts-links-... ergibt. Damit steht zwar die doppelte Höhe für den Flansch jedes Führungsgliedes zur Verfügung. Andererseits ist die Führung in den seitlichen Führungsschienen nicht optimal. Dies ist umso nachteiliger, wenn die Rafflamellenstoren in windigen Lagen eingebaut werden.One possibility of the prior art in this context is that only one lateral end of a slat of a Rafflamellenstores is used with a guide member, so that when viewed from the front of the slat and the guide member, a sequence of guide members right-left-right -Left-... results. Thus, while the double height for the flange of each guide member is available. On the other hand, the guide in the lateral guide rails is not optimal. This is all the more disadvantageous if the Rafflamellenstoren be installed in windy conditions.
Problematisch ist bei den Führungsgliedern gemäss dem Stand der Technik ebenfalls, dass diese eine Dicke aufweisen, welche einen Abstand von aufeinanderliegenden Storenlamellen erfordert, wenn diese eingezogen sind und aufeinanderliegen. Damit einher geht das Problem, dass die Führungsglieder in nicht optimaler Form aufeinanderliegen, wobei dies insbesondere für Storen gilt, bei denen die Führungsglieder entlang einer schrägen Fläche der Storenlamellen angeordnet sind.It is also problematic in the guide members according to the prior art that they have a thickness which requires a distance from superimposed blind slats when they are retracted and lie on one another. This is accompanied by the problem that the guide members are superimposed in a non-optimal form, and this applies in particular to blinds, in which the guide members are arranged along an inclined surface of the blind slats.
Beim Stand der Technik können die Lamellen nicht lagerichtig aufeinander gestapelt werden, weil anstatt der Lamellenbördel die Verdickungen der Führungsnasen am Ende des Führungsgliedschaftes aufeinanderliegen. Zwischen zwei Lamellenbördeln von benachbarten Lamellen bestehen somit Lücken, so dass die Lamellen nicht unterstützt sind und sich die Gewichtsbelastung auf die Führungsgliedschäfte überträgt.In the prior art, the lamellae can not be stacked in the correct position, because instead of the lamellar flanges, the thickening of the guide lugs at the end of the guide member shaft lie on each other. Thus, there are gaps between two lamellar flanging of adjacent lamellae, so that the lamellae are not supported and the weight load is transmitted to the guide link shafts.
Um diesem Problem zu begegnen, werden beim Stand der Technik die Lamellen nicht an beiden Enden mit Führungsgliedern versehen, sondern beispielsweise nur wechselseitig an einem Lamellenende und bei der benachbarten nächsten Lamelle nur am gegenüberliegenden Ende, so dass zwischen drei Lamellen die mittlere Lamelle jeweils ein Führungsglied am rechten Lamellenende und die beiden anderen Lamellen je ein Führungsglied am linken Lamellenende erhalten. Aus dieser wechselseitig einseitigen Bestückung der Lamellen mit Führungsgliedern ergibt sich beim Stand der Technik eine dünnere aber instabile und windanfällige Storenmontage und zwangsläufig ein entsprechend schadensanfälliger Storenbetrieb.In order to counteract this problem, in the prior art, the slats are not provided at both ends with guide members, but for example only mutually at one fin end and at the adjacent next slat only at the opposite end, so that between three slats, the middle slat one guide member at the right end of the lamella and the other two lamellae each receive a guide member on the left end of the lamella. From this mutually one-sided assembly of slats with guide members results in the prior art, a thinner but unstable and wind-prone Storenmontage and inevitably a corresponding damage susceptible Storenbetrieb.

Die
Um diese Nachteile zu überwinden und gleichzeitig eine Führungsgliedkonstruktion anzugeben, die eine einwandfreiere Lamellenführung bei grosser Windstabilität, funktionierendem Lamellenstapel und auf alle bekannten Lamellentypen passende Führungsglieder zur Verfügung zu stellen, ist ein Führungsglied gemäss der vorliegenden Erfindung vorgesehen.In order to overcome these disadvantages and at the same time to provide a guide member construction which ensures a more faultless slat guidance with great wind stability, functioning lamella stack and to provide all known types of lamellae guide members available, a guide member according to the present invention is provided.
Ausgehend von diesem Stand der Technik liegt der Erfindung die Aufgabe zugrunde, ein Führungsglied für einen Rafflamellenstore und ein Rafflamellenstore mit entsprechenden Führungsgliedern anzugeben, welche die oben genannten Nachteile überwindet.Based on this prior art, the present invention seeks to provide a guide member for a Rafflamellenstore and a Rafflamellenstore with corresponding guide members, which overcomes the disadvantages mentioned above.
In diesem Zusammenhang ist es ein Ziel der vorliegenden Erfindung ein universelles Führungsglied bzw. ein universelles Führungsmittel anzugeben, das eine Abfolge von Lamellen eines Rafflamellenstores sicher und bei vielen Windbedingungen in der zugehörigen Seitenführung hält.In this context, it is an object of the present invention to provide a universal guide member or a universal guide means that holds a sequence of slats of a Rafflamellenstores safe and in many wind conditions in the associated side guide.
Diese Aufgaben und Ziele der Erfindung werden bei einem Führungsglied für einen Rafflamellenstore mit einer Vielzahl von Lamellen, das einen Befestigungsflansch aufweist, an den sich ein Führungsschaft anschliesst, der in einen Führungsflansch übergeht, durch die Merkmale des kennzeichnenden Teils des Anspruchs 1 gelöst.These objects and objects of the invention are achieved in a guide member for a multi-fin Venetian blind having a mounting flange to which a guide shaft merges into a guide flange is achieved by the features of the characterizing part of

Ein Rafflamellenstore besteht dann aus einzelnen Lamellen 12, welche mit geeigneten, dem Fachmann bekannten Mitteln miteinander verbunden sind. Die Führungsglieder 2 sorgen dafür, dass die Storen, die in Längsrichtung der Führungsschienen X senkrecht zur Hauptebene der Lamellen 12 auf und ab bewegt werden können, in diesen Führungsschienen X geführt sind. Gleichzeitig sind die Lamellen 12 um ihre Hauptachse 20 verdrehbar, um sie platzsparend verstauen zu können, um bei horizontaler Stellung Licht durch die Lamellenzwischenräume dringen zu lassen und um bei senkrechter oder nahezu senkrechter Stellung der Lamellen einen Sichtschutz und gegebenenfalls einen Zugangsschutz zu gewährleisten. Häufig weisen Lamellen 12 einen verstärkten Rand 1 auf, der auch als Bördel 1 ausgestaltet sein kann, wie er sich aus der
Die Lamellen 12 können aus Kunststoff, zum Beispiel gespritzt, oder aus Metall, beispielsweise gestanzt, hergestellt werden. Die Führungsglieder können sowohl gegossen, gedreht, gepresst, geschmiedet oder gespritzt hergestellt werden, wobei dem Fachmann bekannte Buntmetall-Legierungen, Leichtmetall-Legierungen, Stahl-Legierungen und auch Kunststoffe eingesetzt werden können.The

Der Schaft 4 des Führungsgliedes 2 erstreckt sich entlang der Hauptachse 20 des Führungsglied 2, welche vorteilhafterweise in der Mitte oder im mittleren Bereich einer Lamelle 12 entsprechend deren longitudinalen Ausrichtung montiert wird. An den im Querschnitt vorteilhafterweise runden Schaft 4, dessen Dimension so ausgelegt ist, dass er in die gängigen Führungsschlitze 17 von Führungsschienen X passt, schliesst sich ein flacher, plattenförmiger Befestigungsflansch 6 an, an dem im dargestellten Ausführungsbeispiel zwei Gruppen von Nietschäften 7 bzw. 8 oben und unten auf der Platte vorgesehen sind.

Es ist somit im Zusammenspiel mit der Form der Schaftnase 5 erkennbar, dass durch Drehen des Führungsgliedes 2 um 180° um seine Hauptachse 20, die Führungsnase 5 in die bezüglich der Lamellenebene gegenüberliegende Seite ausgerichtet ist. Somit ist es möglich mit einem Typ von Führungsgliedern 2 beide Orientierungen für die Befestigung an der Lamelle 12 zu gewährleisten. Bei Umdrehen eines Führungsgliedes 2 ragt die Nase 5 in eine andere Seite des hohlen Innenraums 21.It is thus in conjunction with the shape of the
