Description

Die Erfindung betrifft eine Lamelle für eine aus einer Mehrzahl gleichartiger, horizontaler Lamellen bestehende Store, mit einer konvexen Vorderseite und einer konkaven Rückseite, mit wenigstens einer Öffnung für den Durchgang eines Aufzugsorgans und wenigstens zwei im Abstand zueinander angeordneten Öffnungen für den Durchgang jeweils eines Führungsseils. Die Erfindung betrifft zudem eine Store mit solchen Lamellen.The invention relates to a lamella for one of a plurality same, horizontal slats existing store, with a convex front and a concave back, with at least an opening for the passage of an elevator member and at least two spaced openings for the passage one guide rope each. The invention also relates a store with such slats.

Lamellen dieser Art sind bekannt. Sie werden auch als Flachlamellen bezeichnet und sind flexibel, in der Regel ungebördelt und besitzen beispielsweise eine Breite von 100 Millimetern. Bekannte Storen mit solchen Lamellen weisen zwei im Abstand zueinander angeordnete gespannte Führungsseile auf, an denen die Lamellen mittels Aufzugsbändern aufgezogen und herabgelassen werden können. Verglichen mit Storen, bei denen die Lamellen in Führungsschienen geführt sind, sind Storen mit Führungsseilen wesentlich kostengünstiger in der Herstellung und in der Montage.Slats of this type are known. They are also called flat slats are labeled and are flexible, usually unflared and have a width of 100 millimeters, for example. Known blinds with such slats have two spaced apart arranged tensioned guide ropes on which the Slats opened and lowered using elevator belts can be. Compared to blinds in which the slats in Guide rails are guided, are blinds with guide ropes much cheaper to manufacture and assemble.

In der CH 544 215 wird eine Vorrichtung zum Führen der Lamellen beschrieben, die aus Drähten oder Seilen besteht, die zwischen zwei Befestigungspunkten mit festem gegenseitigen Abstand unter Einfügen eines elastischen Elements eingespannt sind und an den Lamellen angreifen. Das elastische Element ist eine an einem Ende fest montierte Blattfeder, die im wesentlichen rechtwinkelig zur Spannrichtung des Drahtes oder des Seiles ausgerichtet ist.In CH 544 215 there is a device for guiding the slats described, which consists of wires or ropes between two fastening points with a fixed mutual distance below Insert an elastic element and are clamped to the Attack slats. The elastic element is one at one end Fixed leaf spring that is essentially rectangular is aligned with the direction of tension of the wire or rope.

Bei den bekannten Lamellen, die für Storen mit Führungsseilen vorgesehen sind, wird als nachteilig angesehen, dass bei einem Behang aus solchen Lamellen der Transmissionsgrad wesentlich grösser ist als bei einer Store mit Führungsschienen.In the known slats for blinds with guide ropes are provided, it is considered disadvantageous that at a The degree of transmittance was significant from such slats is larger than a store with guide rails.

Der Erfindung liegt die Aufgabe zugrunde, eine Lamelle der genannten Art zu schaffen, mit der eine Store mit kleinerem Transmissionsgrad hergestellt werden kann und die dennoch kostengünstig herstellbar und funktionssicher ist. The invention has for its object a lamella to create a store with a smaller one Transmittance can be made and still inexpensive is manufacturable and reliable.

Die Aufgabe ist bei einer gattungsgemässen Lamelle gemäss Anspruch 1 gelöst. Die Öffnungen für den Durchgang der Führungsseile sind bei der erfindungsgemässen Lamelle bezüglich der konvexen Vorderseite nach rückwärts versetzt, was einerseits eine wesentliche Verkleinerung der Öffnungen und anderseits einen wesentlich besseren Lamellenschluss und damit einen kleineren Transmissionsgrad des Behanges und also einen kleineren g-Wert ermöglicht.The object is achieved in a generic slat according to claim 1. The openings for the passage of the guide ropes are at the lamella according to the invention with respect to the convex front moved backwards, which on the one hand is a significant reduction of the openings and on the other hand a much better one Slat closure and thus a lower transmittance of the Curtains and thus a smaller g-value enabled.

Prägungen zentrieren die Lamellen beim Schliessen des Behangs und führen auch zu einer grösseren Stabilität des Behanges gegenüber den bekannten Lamellen. Die Öffnungen für den Durchgang der Führungsseile sind in Grund der Prägungen angeordnet. Es hat sich gezeigt, dass tropfenförmige und somit vergleichsweise flache Prägungen auch für die Herstellung vorteilhaft sind, da hierbei ein Zerreissen des vergleichsweise flachen Bleches vermieden werden kann.Embossings center the Slats when closing the curtain and also lead to one greater stability of the curtain compared to the known Slats. The openings for the passage of the guide ropes are in Arranged due to the embossing. It has been shown to be teardrop-shaped and therefore comparatively flat embossing also advantageous for production are, because here a tearing of the comparatively flat sheet metal can be avoided.

Weitere vorteilhafte Merkmale ergeben sich aus den abhängigen Patentansprüchen, der nachfolgenden Beschreibung sowie der Zeichnung.Further advantageous features result from the dependent ones Claims, the description below and the Drawing.

Die Fig. 1 zeigt eine in einer Fensteröffnung 15 montierte Store 1 mit einer Vielzahl von Lamellen 2, die an zwei Führungsseilen 3, von denen hier lediglich eines gezeigt ist, vertikal verschiebbar geführt sind. Zum Aufziehen und Herablassen der Lamellen 2 sind zwei Aufzugsbänder 4, von denen ebenfalls lediglich eines gezeigt ist, vorgesehen, die jeweils an einem unteren Ende an einer untersten Lamelle 2' und an einem oberen Ende an einer Wickelrolle 5 befestigt sind. Mittels einer Welle 6 und einem hier nicht gezeigten üblichen Betätigungsorgan können die Wickelrollen 5 gedreht und damit die Store 1 aufgezogen oder herabgelassen werden.1 shows a store mounted in a window opening 15 1 with a large number of slats 2 attached to two guide ropes 3, of which only one is shown here, can be moved vertically are led. For opening and lowering the slats 2 are two elevator belts 4, of which also only one is shown provided, each at a lower end a lowest slat 2 'and at an upper end on one Winding roll 5 are attached. By means of a shaft 6 and a The usual actuator not shown here can the winding rollers 5 rotated and thus the store 1 opened or lowered become.

Die Lamellen 2 weisen jeweils eine konvexe Vorderseite 12 und eine konkave Rückseite 13 auf und bestehen aus vergleichsweise dünnem und flexiblem sowie ungebördeltem Blech, vorzugsweise Aluminiumblech. Für den Durchgang der gespannten Führungsseile 3 weisen die Lamellen 2 jeweils zwei im Abstand zueinander angeordnete gleiche Prägungen 7 auf, von denen in der Zeichnung lediglich eine gezeigt ist. Im Grund jeder Prägung befindet sich ein Langloch 8, das vorzugsweise eine Stanzung ist und durch das ein Seilzug 3 hindurchgezogen ist. Wie insbesondere die Fig. 3 zeigt, ist der Rand 7a der Prägungen 7 tropfenförmig, wobei bei geschlossenen Lamellen 2 der bauchige Bereich 7b unten und der spitze Bereich 7c oben ist. Über den Öffnungen 8 sind die Prägungen 7 als vergleichsweise langgezogene, V-förmige Flanken 7d ausgebildet, welche die Lamelle 2 beim Schliessen zentrieren und führen. Unterhalb jeder Prägung 7 ist an einem unteren Rand 14 der Lamelle 2 eine V-förmige Ausbuchtung 11 eingearbeitet, die im Gegensatz zu den Prägungen 7 auf der Vorderseite 12 vorragt. Diese Ausbuchtungen 11 bilden weitere Freistellungen für die Führungsseile 3 und dienen ebenfalls zur Stabilisierung der Lamellen 2.The slats 2 each have a convex front 12 and a concave back 13 and consist of comparatively thin and flexible as well as unflared sheet, preferably Aluminum sheet. For the passage of the tensioned guide ropes 3 the slats 2 each have two spaced apart same embossings 7, of which only in the drawing one is shown. There is a in the base of each embossing Elongated hole 8, which is preferably a punch and through the one Cable 3 is pulled through. As in particular FIG. 3 shows, the edge 7a of the embossments 7 is drop-shaped, wherein at closed slats 2 the bulbous area 7b below and the peak area 7c is above. Over the openings 8 are the Embossments 7 as comparatively elongated, V-shaped flanks 7d formed, which center the lamella 2 when closing and lead. Below each embossment 7 is on a lower edge 14 of the lamella 2 a V-shaped bulge 11 is incorporated, which, in contrast to the embossments 7, projects on the front 12. These bulges 11 form further exemptions for the guide ropes 3 and also serve to stabilize the Slats 2.

Für die Aufzugsbänder 4 sind ebenfalls Prägungen 9 vorgesehen, die jedoch entsprechend der Breite der Bänder 4 in Längsrichtung der Lamellen 2 verlaufende Langlöcher 10 aufweisen.Embossments 9 are also provided for the elevator belts 4, which, however, correspond to the width of the belts 4 in the longitudinal direction the slats 2 have elongated holes 10.

Ist die Store 1 gemäss Fig. 1 geschlossen, so liegen die unteren Ränder 14 der Storen 2 weitgehend dicht jeweils an der Aussenseite 12 einer benachbarten unteren Lamelle 2 an. Die Anlage der unteren Ränder 14 ist dann besonders dicht, wenn für die Aufzugsbänder 4 an den unteren Rändern 14 ebenfalls Ausbuchtungen 16 vorgesehen sind. Auch bei völlig geschlossenen Lamellen 2 ist damit ein gestreckter Durchgang der Führungsseile 3 und auch der Aufzugsbänder 4 gewährleistet. Die Fig. 4 zeigt den Durchgang eines Führungsseiles 3 durch die Öffnungen 8 der Lamellen 2. Wie ersichtlich sind die Lamellen 2 jeweils an den Flanken 7d der Prägungen 7 und an den Ausbuchtungen 11 an die Führungsseile 3 angelegt und an diesen seitlich geführt.If the store 1 is closed according to FIG. 1, the lower ones are located Edges 14 of the blinds 2 are largely tight on the outside 12 of an adjacent lower lamella 2. The plant of the lower edges 14 is particularly tight when for the elevator belts 4 at the lower edges 14 also bulges 16 are provided. Even with completely closed slats 2 thus an elongated passage of the guide ropes 3 and also the Elevator belts 4 guaranteed. 4 shows the passage a guide rope 3 through the openings 8 of the slats 2. How the slats 2 can be seen in each case on the flanks 7d of the Embossings 7 and on the bulges 11 on the guide ropes 3 laid out and guided to the side.

Die Lamellen 2 sind üblicherweise mittels einer hier nicht gezeigten Schwenkvorrichtung verschwenkbar. Solche Vorrichtungen sind dem Fachmann bekannt und werden deshalb hier nicht weiter erläutert.The slats 2 are usually not by means of one here shown swivel device pivotable. Such devices are known to the person skilled in the art and are therefore not further here explained.
