Description

Die Erfindung betrifft eine Rafflamellenjalousie mit einem Behang aus im wesentlichen Z-förmig profilierten Lamellen mit einem Mittelabschnitt und zwei komplementären, sich beidseits unter stumpfen bis rechten Winkeln anschließenden, gleich breiten Seitenabschnitten, wobei Tragorgane zum Tragen und Wenden sowie Aufzugsorgane zum Raffen bzw. Herablassen der Lamellen dienen.The invention relates to a Roman blind with a curtain made of essentially Z-shaped slats with a central section and two complementary, equally wide side sections adjoining on both sides at obtuse to right angles, supporting elements for carrying and turning as well as elevator elements for gathering or lowering the Serve slats.

Derartige Rafflamellenjalousien mit Z-förmigen Lamellen sind vielfältig bekannt. Die Neigung des Mittelabschnitts gegenüber den beiden Seitenabschnitten hat dabei den Vorteil, daß die öffnungen für das alle Mittelabschnitte der Lamellen durchsetzende Aufzugsorgan trotz eines großen Wendewinkels der Lamellen relativ klein sein können.Such Roman blinds with Z-shaped slats are widely known. The inclination of the middle section with respect to the two side sections has the advantage that the openings for the elevator element passing through all the middle sections of the slats can be relatively small despite a large turning angle of the slats.

Die Z-Form der Lamellen der neuen Rafflamellenjalousie hat demgegenüber eine gänzlich andere Ursache und Bedeutung. Dieser neuen Rafflamellenjalousie liegt.die Aufgabe zugrunde, einen im geschlossenen Zustand besonders kompakten und insbesondere wärmedämmenden Lamellenbehang anzugeben.In contrast, the Z-shape of the slats of the new Roman blinds has a completely different cause and meaning. This new Roman blind is based on the task of specifying a particularly compact and in particular heat-insulating slatted curtain when closed.

Diese Aufgabe wird erfindungsgemäß - mit Hilfe an sich bekannter Z-Lamellen - dadurch gelöst, daß die Breite der Lamellen-Seitenabschnitte im wesentlichen gleich dem Abstand der Lamellen (Teilungsmaß) ist und im voll gewendeten Zustand jeder Seitenabschnitt einer Lamelle mit deren angrenzendem Mittelabschnitt sowie dem komplementären Seitenabschnitt nebst angrenzendem Mittelabschnitt einer benachbarten Lamelle ein im wesentlichen geschlossenes Hohlprofil bildet. Während bei herkömmlichen Rafflamellenjalousien die Lamellenbreite nur wenig größer als das Teilungsmaß ist, hat die neue Rafflamellenjalousie Lamellen, deren Gesamtbreite im wesentlichen dem doppelten Teilungsmaß entspricht, so daß im voll gewendeten, also geschlossenen Zustand jede Lamelle ihre beiden Nachbarlamellen je zur Hälfte überdeckt.This object is achieved - with the help of known Z-slats - in that the width of the slat side sections is substantially equal to the distance between the slats (pitch) and in the fully turned condition each side section of a slat with its adjacent central section and the complementary side section forms an essentially closed hollow profile together with an adjacent central section of an adjacent lamella. While in conventional Roman blinds the slat width is only slightly larger than the pitch, the new Roman blind has slats, the total width of which essentially corresponds to twice the pitch, so that when fully turned, i.e. closed, each slat covers half of its two neighboring slats.

Die von den Luftpolstern in den Hohlprofilen der geschlossenen Rafflamellenjalousie bewirkte gute Wärmedämmung läßt sich weiter verbessern, wenn die Lamellen im Bereich des Mittelabschnitts geteilt und die Teile durch eine schlecht wärmeleitende Brücke miteinander verbunden sind. Diese Maßnahme wird vornehmlich bei Lamellen aus Metall, insbesondere Aluminium, Anwendung finden, die gute mechanische Eigenschaften mit guter Wärmeleitfähigkeit verbinden und insofern den Wärmedurchgang begünstigen. Wird die Wärmeleitung im Bereich der Mittelabschnitte jedoch unterbrochen, so kann diesem nachteiligen Aspekt wirksam begegnet werden.The good thermal insulation caused by the air cushions in the hollow profiles of the closed Roman blinds can be further improved if the slats are divided in the area of the central section and the parts are connected to one another by a poorly heat-conducting bridge. This measure will be used primarily with fins made of metal, in particular aluminum, which combine good mechanical properties with good thermal conductivity and thus favor the heat transfer. However, if the heat conduction is interrupted in the area of the central sections, this disadvantageous aspect can be effectively countered.

Vornehmlich solche im Bereich des Mittelabschnitts geteilte Lamellen können aus unterschiedlich bearbeiteten und/oder aus unterschiedlichen Werkstoffen bestehenden Teilen hergestellt sein. Es lassen sich auf diese Weise eine Vielzahl von lichtbeeinflussenden Wirkungen erzielen, und zwar sowohl im geöffneten als auch im gewendeten (geschlossenen) Zustand der Jalousie.Such slats, which are divided in the area of the central section, can be machined from differently and / or parts made of different materials. In this way, a variety of light-influencing effects can be achieved, both in the open and in the turned (closed) state of the blind.

Andere vorteilhafte Weiterbildungen und Ausgestaltungen der neuen Rafflamellenjalousie ergeben sich aus der nachfolgenden Beschreibung von Ausführungsbeispielen und sind Gegenstand von Unteransprüchen.Other advantageous developments and refinements of the new Roman blinds result from the following description of exemplary embodiments and are the subject of subclaims.

Die Figuren 1 und 2 stellen - wie gesagt - eine einfache Ausführungsform nur eines Ausschnitts des Lamellenbehangs einer im übrigen allgemein bekannten Raffla- mellenjalousie dar. Die im ganzen mit 1 bezeichneten Lamellen bestehen jeweils aus einem Mittelabschnitt 2 und beidseitigen Seitenabschnitten 3a und 3b. Die Lamellen 1 sind mit Hilfe von schematisch angedeuteten Nippeln 4, welche an den Mittelabschnitten 2 befestigt sind, in nicht dargestellten Seitenführungsschienen vertikal geführt. Im Bereich der freien Ränder der Seitenabschnitte 3a, 3b sind die Lamellen 1 an Trag- und Wendeorganen 5 mit Hilfe von Verbindungsstücken 6 angelenkt.Figures 1 and 2 show - as said - a simple embodiment, only a section of the Lamellenbehangs one side portions in the rest of well-known R affla- Melle jalousie represents the slats designated as a whole by 1 each consist of a central portion 2 and both sides 3a and 3b.. The slats 1 are guided vertically in the side guide rails, not shown, with the aid of schematically indicated nipples 4, which are fastened to the central sections 2. In the area of the free edges of the side sections 3a, 3b, the lamellae 1 are articulated on the supporting and turning elements 5 with the aid of connecting pieces 6.

Der Mittenabstand benachbarter Nippel 4 (bzw. benachbarter Verbindungsstücke 6) definiert das Teilungsmaß des Jalousiebehangs; es ist im Beispiel mit x bezeichnet. Mit B ist die Gesamtbreite einer Lamelle 1 bezeichnet, mit b die wirksame Breite eines Seitenabschnitts 3a bzw. 3b. Weicht der Winkel zwischen dem Mittelabschnitt 2 und den angrenzenden Seitenabschnitten 3a, 3b von 90° ab (stumpfer Winkel), so geht ein Teil des Mittelabschnitts 2 in die wirksame Breite des Seitenabschnitts 3a bzw. 3b ein.The center distance between adjacent nipples 4 (or adjacent connecting pieces 6) defines the pitch of the blind curtain; in the example it is labeled x. B denotes the total width of a lamella 1, b denotes the effective width of a side section 3a or 3b. If the angle between the middle section 2 and the adjacent side sections 3a, 3b deviates from 90 ° (obtuse angle), part of the middle section 2 is included in the effective width of the side section 3a or 3b.

Vor allem Fig. 2 macht deutlich, daß die wirksame Breite b der Seitenabschnitte 3a, 3b gleich dem Teilungsmaß x ist, so daß eine Lamelle von der Gesamtbreite B den Seitenabschnitt 3a der ihr auf einer Seite benachbarten Lamelle 1 und den Seitenabschnitt 3b der ihr auf der anderen Seite benachbarten Lamelle 1 überdeckt und mit diesen Seitenabschnitten sowie den beteiligten, jeweils dazwischenliegenden Mittelabschnitten 2 zwei Hohlprofile 7 bildet. Dabei liegen die Bördelränder 8 entlang den freien Kanten der Lamellen-Seitenabschnitte 3a, 3b an den beteiligten Mittelabschnitten 2 an.In particular, Fig. 2 makes it clear that the effective width b of the side sections 3a, 3b is equal to the pitch x, so that a slat of the total width B on the side section 3a of the slat 1 adjacent to it on one side and the side section 3b on it covers the other side adjacent lamella 1 and forms two hollow profiles 7 with these side sections and the involved middle sections 2 lying between them. The flanged edges 8 lie along the free edges of the lamella side sections 3a, 3b on the middle sections 2 involved.

Beim Ausführungsbeispiel der Figuren 3 und 4 schließen die Seitenabschnitte 3a, 3b stumpfe Winkel mit dem Mittelabschnitt 2 ein. Sie sind um die Achse 9 des Nippels 4 schwenkbar, welcher in der Seitenschiene 10 geführt ist und in diesem Beispiel einen Kurbelansatz 11 besitzt (Fig. 4).In the exemplary embodiment in FIGS. 3 and 4, the side sections 3a, 3b form obtuse angles with the central section 2. They can be pivoted about the axis 9 of the nipple 4, which is guided in the side rail 10 and in this example has a crank shoulder 11 (FIG. 4).

Die Trag- und Wendeorgane 5 sind endseits der Lamellen 1 angeordnet. Dabei greift nur das in der Zeichnung rechte Trag- und Wendeorgan 5 mit Hilfe seiner Verbindungsstücke 6 am freien Rand des zugehörigen Seitenabschnitts 3b an. Das andere - linke - Trag- und Wendeorgan 5 greift gar nicht unmittelbar an den Lamellen 1, sondern (mit Hilfe gleichartiger Verbindungsstücke 6) an den freien Enden der Nippel-Kurbeln 11 mit Hilfe daran befestigter Zapfen 12 an. Entsprechende Zapfen 13 sind übrigens zur Anlenkung des (rechten) Trag- und Wendeorgans 5 im Bereich der freien Ränder der Seitenabschnitte 3b endseits der Lamellen 1 auch vorgesehen (Fig. 4).The support and turning elements 5 are arranged at the ends of the slats 1. Only the support and turning element 5 on the right in the drawing attacks with the aid of its connecting pieces 6 on the free edge of the associated side section 3b. The other - left - support and turning element 5 does not engage directly on the lamellae 1, but (with the aid of similar connecting pieces 6) on the free ends of the nipple cranks 11 with the aid of pins 12 fastened thereon. Corresponding pins 13 are also provided for the articulation of the (right) support and turning element 5 in the region of the free edges of the side sections 3b at the end of the lamellae 1 (FIG. 4).

Die Fig. 3 und 4 stellen mit ausgezogenen Linien den geschlossenen Zustand der Rafflamellenjalousie dar, in welchem die Lamellen 1 wiederum Hohlprofile 7 bilden. In diese Stellung gelangen die Lamellen 1, wenn die Trag- und Wendeorgane 5 gemäß den Pfeilen 14 relativ zueinander bewegt werden. Eine entgegengesetzt gerichtete Relativbewegung der Trag- und Wendeorgane 5 läßt die Lamellen 1 in die strich-punktiert angedeutete Offenlage schwenken; dabei bewegt sich jedes an dem in den Zeichnungsfiguren rechten Trag- und Wendeorgan 5 angebrachtes Verbindungsstück 6 auf einem Viertelkreis 15, welcher für die strich-punktiert dargestellte Lamelle 1 in Figur 3 ebenfalls strich-punktiert angegeben ist. Das zugehörige Trag- und Wendeorgan 5 verlagert sich parallel zu seiner dargestellten Stellung nach rechts (nicht dargestellt); eine entsprechende Parallelverlagerung erfährt das andere (linke) Trag- und Wendeorgan 5 aufgrund der damit einhergehenden Schwenkung aller Kurbeln 11.3 and 4 show with solid lines the closed state of the Roman blind, in which the slats 1 in turn form hollow profiles 7. The slats 1 reach this position when the support and turning elements 5 are moved relative to one another according to the arrows 14. An oppositely directed relative movement of the supporting and turning elements 5 allows the slats 1 to pivot into the open position indicated by dash-dotted lines; each connecting piece 6 attached to the support and turning element 5 on the right in the drawing figures moves on a quarter circle 15, which for the lamella 1 shown in dash-dotted lines is also indicated by dash-dotted lines in FIG. The associated support and turning element 5 moves parallel to its position shown to the right (not shown); the other (left) support and turning element 5 experiences a corresponding parallel displacement due to the associated pivoting of all cranks 11.

Figur 5 zeigt im Teilquerschnitt den Aufbau einer längsgeteilten Lamelle 1. Die Seitenabschnitte 3a und 3b bestehen dabei aus unterschiedlichem Material, wie die verschiedene Schraffierung deutlich macht. Dieses Material kann beispielsweise ein Kunststoff sein, und die Unterschiede können sich auf unterschiedliche Bearbeitung (z.B. Prismenausbildung in glasklarem Kunststoff, wobei bestimmte Prismenkanten zur Lichtlenkung beschichtet sein können) beschränken. Der Seitenabschnitt 3a setzt sich in einem Mittelschenkel-Abschnitt 2a und der Seitenabschnitt 3b in einem Mittelschenkel-Abschnitt 2b fort. Zwischen den Abschnitten 2a, 2b ist eine Trag- oder Verbindungsleiste 2c vorgesehen, welche entlang den Verbindungsflächen 2d mit den Abschnitten 2a, 2b beispielsweise verklebt ist und auf diese Weise insgesamt den Mittelabschnitt 2 der Lamelle 1 bildet.FIG. 5 shows a partial cross section of the structure of a longitudinally divided lamella 1. The side sections 3a and 3b consist of different material, as the different hatching shows. This material can be a plastic, for example, and the differences can be limited to different processing (e.g. prism formation in crystal-clear plastic, whereby certain prism edges can be coated for light control). The side section 3a continues in a middle leg section 2a and the side section 3b continues in a middle leg section 2b. Between the sections 2a, 2b, a support or connecting bar 2c is provided, which is glued to the sections 2a, 2b along the connecting surfaces 2d, for example, and in this way forms the overall central section 2 of the lamella 1.

Figur 6 zeigt eine wieder andere Lamellenausbildbng, und zwar auch im vertikalen Ausschnitt benachbarter Lamellen in der Schließstellung. Hier besteht der Mittelabschnitt 2 im wesentlichen aus einer kompakten Leiste 2c, in die entsprechend kürzere Mittelleisten-Abschnitte 2a, 2b der Seitenabschnitte 3a, 3b fluchtend eingreifen; der Abkröpfwinkel zwischen den Seitenabschnitten 3a, 3b und den Mittelleisten-Abschnitten 2a, 2b weicht auch in diesem Falle von 90° ab. Die Leiste 2c kann (ebenso wie im Beispiel der Figur 5) aus besonders schlecht wärmeleitendem Material bestehen.FIG. 6 shows yet another lamella design, also in the vertical section of adjacent lamellae in the closed position. Here, the middle section 2 essentially consists of a compact bar 2c, in which correspondingly shorter middle bar sections 2a, 2b of the side sections 3a, 3b engage in alignment; the offset angle between the side sections 3a, 3b and the central strip sections 2a, 2b also deviate from 90 ° in this case. The strip 2c (as in the example in FIG. 5) can consist of particularly poorly heat-conducting material.

In entsprechend geformte Randbördelungen 16 der Seitenabschnitte 3a, 3b sind Dichtleisten 17 (aus Gummi, Kunststoff o. dgl.) mit Hilfe verdickter Ränder 18 eingeführt. In dem in Figur 6 dargestellten geschlossenen Zustand der Jalousie liegen die Lippen 19 der Dichtleisten 17 an der Leiste 2c des Mittelabschnitts 2 der jeweiligen Nachbarlamelle 1 an, so daß der Hohlraum 7 wirksam abgedichtet ist.Sealing strips 17 (made of rubber, plastic or the like) are inserted into appropriately shaped edge flanges 16 of the side sections 3a, 3b with the aid of thickened edges 18. In the closed state of the blind shown in FIG. 6, the lips 19 of the sealing strips 17 rest against the strip 2c of the central section 2 of the respective neighboring slat 1, so that the cavity 7 is effectively sealed.

Gemäß dem in den Figuren 7 und 8 dargestellten Ausführungsbeispiel sind Dichtleisten 20 Teil der Leiste 2c, welche auch hier den größten Teil des Mittelabschnitts 2 ausmacht. Im geöffneten Zustand der Lamellen.1 sind die Dichtleisten 20 gestreckt. Beim Schließen kommen die Bördelungen 16 der jeweils beiden benachbarten Lamellen 1 zur Anlage an die Leiste 20 (Figur 7). Wenn die Rafflamellenjalousie völlig geschlossen ist und jeweils benachbarte Lamellen 1 Hohlräume 7 gebildet haben, sind die Dichtleisten 20 in dichtende Anlage an den Bördelungen 16 verformt (Figur 8).According to the exemplary embodiment shown in FIGS. 7 and 8, sealing strips 20 are part of the strip 2c, which also makes up the largest part of the central section 2 here. In the open state of the slats. 1, the sealing strips 20 are stretched. When closing, the flanges 16 of the two adjacent slats 1 come to rest against the bar 20 (Figure 7). When the Roman blind is completely closed and adjacent slats 1 have formed cavities 7, the sealing strips 20 are deformed in sealing contact with the flanges 16 (FIG. 8).
