Description

Die Erfindung betrifft einen Rolladen od. dgl. bewegliche Verschlussfläche aus mehreren mit ihren Längsseiten aneinandergelenkten Lamellen oder Profilstäben, deren Außenflächen -- zumindest in Schließstellung des Rolladens -- eine Sichtfläche bilden. Eine Längskante oder -seite der Lamelle/n ist als rinnenförmige Lagerschale ausgebildet, die in seitlichem Abstand zur Rolladenfläche verläuft sowie zur Bildung eines Gelenks eine im Querschnitt hakenähnliche Längsseite der benachbarten Lamelle aufnimmt.The invention relates to a shutter od. Like. Movable closure surface of several with their longitudinal sides hinged slats or profile bars whose outer surfaces - at least in the closed position of the shutter - form a visible surface. A longitudinal edge or side of the lamella / s is designed as a groove-shaped bearing shell which extends at a lateral distance from the roller shutter surface and, in order to form a joint, receives a hook-like longitudinal side of the adjacent lamella.

Derartige aus einer Aluminiumlegierung stranggepresste Rolläden sind beispielsweise in der Schrift zu DE-U-87 12 982 mit querschnittlich gekrümmten Lamellen offenbart und dienen dem zeitweiligen Verschließen der Öffnungen von Fenstern, Türen oder anderen Gebäudedurchbrüchen sowie als Lamellentüren an Fahrzeugaufbauten oder bei Möbeln. Sie sind mit dem Vorzug versehen, auf einfache Weise zusammengesetzt werden zu können.Such extruded from an aluminum alloy shutters are disclosed, for example, in the document to DE-U-87 12 982 with cross-sectionally curved slats and are used to temporarily close the openings of windows, doors or other Gebäudedurchbrüchen and as slatted doors to vehicle bodies or furniture. They are given the advantage of being able to be put together in a simple way.

Der deutschen Gebrauchsmusterschrift G 93 10 826.5 ist eine Rollladenleiste aus einem im Walzverfahren profilierten dünnen Blech aus Aluminiumlegierung zu entnehmen, die zur Versteifung einen Einsatz aufweist und im übrigen innen mit Isoliermaterial befüllt ist. Dazu sind die Hauptwände der Profilleiste mit Rillen versehen, die eine Einbuchtung in das Innere der Leiste darstellen und so gestaltet sind, dass sie den Einsatz in der richtigen Position halten. Die Rillen sind so gestaltet, dass es nicht erforderlich ist, bei der Herstellung der Leiste Vorkehrungen zu treffen, um zu verhindern, dass der Einsatz verrutscht bevor das Isoliermaterial eingefüllt worden ist und sich verfestigt hat. Nachdem die Verfestigung stattgefunden hat, ist diese Funktion der Rillen nicht mehr notwendig. Sie sind jedoch weiterhin von Nutzen, um die Wand der Leiste zu versteifen und um der Leiste ein ästhetisches Erscheinungsbild zu geben. Als Nachteil hat sich erwiesen, dass durch die Vielzahl von aneinandergelenkten Profilstäben oder Lamellen aus Aluminium mit ebener -- durch eine Eloxierschicht oberflächenveredelter -- Sichtfläche schon geringste Unterschiede des Reflektionsgrades optisch sehr stark auffallen.The German Utility Model G 93 10 826.5 is to remove a roller shutter from a profiled in the rolling process thin sheet of aluminum alloy, which has an insert for stiffening and otherwise filled inside with insulating material. For this purpose, the main walls of the profile strip are provided with grooves, which form a recess in the interior of the bar and are designed so that they keep the insert in the correct position. The grooves are designed so that it is not necessary to take precautions in the manufacture of the strip to prevent the insert from slipping before the insulating material has been filled in and solidified. After the solidification has taken place, this function of the grooves is no longer necessary. However, they continue to be useful for stiffening the wall of the bar and for giving the bar an aesthetic appearance. A disadvantage has been found that due to the large number of mutually articulated profile bars or fins made of aluminum with level - surface-refined by an anodization - Visible surface very small differences in reflectance visually very strong.

Angesicht dessen hat sich der Erfinder das Ziel gesetzt, diese Mängel zu beseitigen und die Sichtfläche derartiger Rolladenlamellen oder -profile zu verbessern. Zudem kann der Gelenkbereich effizienter gestaltet werden.In view of this, the inventor has set the goal to eliminate these shortcomings and to improve the visible surface of such roller shutter slats or profiles. In addition, the joint area can be made more efficient.

Zur Lösung dieser Aufgabe führt die Lehre des unabhängigen Anspruches; die Unteransprüche geben günstige Weiterbildungen an.To achieve this object, the teaching of the independent claim; the dependent claims indicate favorable developments.

Erfindungsgemäß ist die Außenfläche der Lamelle bzw. des Profilstabes durch parallele Linien in mehrere Längsfelder oder Flächenstreifen unterteilt, und wenigstens eines der Längsfelder weist eine querschnittlich gekrümmte Oberflächenkontur auf. Dank dieser Maßgabe wird der erwähnte optisch negative Effekt weitestgehend unterbunden; die ebene und glatte Sichtfläche der einzelnen Lamellen wird durch aneinandergereihte Wellen nur geringer Tiefe unterbrochen; solche Wellen -- von bevorzugt etwa 8 mm bis 10 mm Breite -- können durch Strangpressen sehr genau hergestellt werden.According to the invention, the outer surface of the lamella or of the profile bar is subdivided by parallel lines into a plurality of longitudinal fields or surface strips, and at least one of the longitudinal fields has a cross-sectionally curved surface contour. Thanks to this requirement, the aforementioned optically negative effect is largely prevented; the flat and smooth visible surface of the individual lamellae is interrupted by waves of only a shallow depth; such waves - of preferably about 8 mm to 10 mm wide - can be made very accurately by extrusion.

Von besonderer Bedeutung ist die Möglichkeit, die Oberflächenkontur des Längsfeldes konkav zu gestalten und die parallelen Linien als Kammlinien auszubilden oder aber eine solche Oberflächenkontur konvex zu formen sowie jene parallelen Linien als tiefer liegende Tallinien zu konzipieren. In beiden Ausgestaltungen soll der -- als Kamm- oder als Öffnungswinkel zu bezeichnende -- Querschnittswinkel zwischen 170° und 178° liegen, bevorzugt größer als 175° sein.Of particular importance is the ability to make the surface contour of the longitudinal field concave and form the parallel lines as ridge lines or convex to form such a surface contour as well as to design those parallel lines as lower lying Tallinien. In both embodiments, the cross-sectional angle to be designated as a comb or as an opening angle should be between 170 ° and 178 °, preferably greater than 175 °.

Durch diese Vorgehensweise wird an der Lamellensichtseite eine Strukturierung erzielt, ohne dass das Gesamtbild der Rollpanzeransicht in der gewünschten eleganten, ruhigen Flächenwirkung zerstört würde.This procedure achieves structuring on the lamellae side without destroying the overall appearance of the turret view in the desired elegant, quiet surface effect.

Nach einem weiteren Merkmal der Erfindung kann sich die Oberflächenkontur des Längsfeldes aus Abschnitten mit unterschiedlichen Krümmungsradien zusammensetzen - beispielsweise schließt an einen mittleren Abschnitt der Oberflächenkontur beidseits jeweils ein Abschnitt geringerer Krümmung an.According to a further feature of the invention, the surface contour of the longitudinal field of sections with different radii of curvature may be composed - for example, connects to a central portion of the surface contour on both sides in each case a portion of lesser curvature.

Erfindungsgemäß berühren sich die einzelnen Lamellen auf der Sichtseite in Schließstellung des Rolladens nahezu, wodurch sich die Trennung zwischen den einzelnen Profilen harmonisch in die gewollte Wellenteilung einfügt.According to the invention, the individual lamellae touch on the visible side in the closed position of the shutter almost, whereby the separation between the individual profiles fits harmoniously into the desired wave pitch.

Besonders vorteilhaft hat sich die konkave Wellung dadurch erwiesen, dass zwischen den aneinandergereihten vertieften Wellen die erwähnten Kammlinien als erhabene Rippen verlaufen; auf diesen zeichnen sich -- durch unachtsame Handhabung od. dgl. Eingriffe -- gegebenenfalls entstehende Schürfungen ab und letztere fallen dadurch optisch kaum auf.Particularly advantageously, the concave curvature has been proven by the fact that between the successive recessed waves the mentioned ridge lines run as raised ribs; These are characterized - by careless handling od. Like. Interventions - possibly resulting abrasions and the latter are characterized by hardly visually.

Vorteilhafterweise soll der maximale Abstand einer durch die Kammlinien bzw. der Tallinien bestimmten Ebene zur gekrümmten Oberflächenstruktur unter etwa einem Hundertstel der Lamellenhöhe liegen, bevorzugt zwischen 1 % und 3 % der Breite des Längsfeldes betragen. Insbesondere soll dieser maximale Abstand bei einem Längsfeld von 10 mm bis 11 mm etwa 0,1 mm bis 0,3 mm messen.Advantageously, the maximum distance of a plane determined by the ridgelines or the valley lines to the curved surface structure should be less than about one hundredth of the lamella height, preferably between 1% and 3% of the width of the longitudinal field. In particular, this maximum distance should measure about 0.1 mm to 0.3 mm in a longitudinal field of 10 mm to 11 mm.

Nach einem weiteren Merkmal der Erfindung ist als Verhältnis der Breite des Längsfeldes zum maximalen Abstand jene Ebene der Kammlinien bzw. der Tallinien von der gekrümmten Oberflächenkontur -- also das Verhältnis der Wellenabstände zur Wellentiefe bzw. -höhe -- etwa 65 zu 1 vorgesehen; hierdurch wirkt die Wellung optisch elegant, zudem ist die Anpassfähigkeit bzw. Funktion einer Führungsprofildichtung auf die Oberfläche des Rollpanzers noch gegeben.According to a further feature of the invention is provided as the ratio of the width of the longitudinal field to the maximum distance that plane of the ridgelines or the valley lines of the curved surface contour - ie the ratio of the shaft spacings to wave depth or height - about 65 to 1; As a result, the curl looks visually elegant, also the adaptability or function of a guide profile seal on the surface of the rolling armor is still given.

Zur Verbesserung des Gelenkes an dem Rolladen der eingangs genannten Art weist die rinnenartige Lagerschale an ihrem Rinnenende einen Sitz für eine freie Kante der hakenartigen Längsseite auf und/oder einen querschnittlich i. w. geraden Rinnenschenkel als Anschlag für einen geraden Hakensteg der hakenartigen Längsseite. Jenem Sitz liegt ein Schenkel eines dämpfend wirkenden Kunststoffprofils auf, das sich zwischen den gegeneinander bewegten Flächen der beiden Gelenkteile erstreckt.To improve the joint on the shutter of the type mentioned, the groove-like bearing shell at its gutter end a seat for a free edge of the hook-like longitudinal side and / or a cross-section iw straight trough legs as a stop for a straight hook web of the hook-like longitudinal side. In that seat is a leg of a damping acting plastic profile, which extends between the mutually moving surfaces of the two joint parts.

Hierzu ist an der in Fig. 1 oberen Längsseite der Lamellen 12 an diese ein Gelenkteil 14 als hakenartige Kante angeformt, die in ein rinnenartiges Gegengelenkteil 16 der benachbarten Lamelle 12 eingeschoben wird und zu einem Rolladengelenk 18 ergänzt.A total of vertically movable shutters 10 has a plurality of interconnected on their longitudinal sides and mutually pivotable slats or profile bars 12 which are extruded from an aluminum alloy. For this purpose, a hinge part 14 is formed as a hook-like edge on the in Fig. 1 upper longitudinal side of the slats 12, which is inserted into a channel-like counter-joint part 16 of the adjacent slat 12 and added to a shutter joint 18.

Das in Fig. 1 obere Gelenkteil 14 der Lamelle 12 umfasst -- querschnittlich gesehen -- eine Abwinkelung 20, ein von dieser nach oben gerichtetes Kurvenstück 22 mit von dessen Ende ausgehendem, zur Ebene E der Lamelle 12 geringfügig geneigtem Hakensteg 24, dessen abwärts gerichteter freier Kante 25 ein ebenfalls von der Abwinkelung 20 abragender, zur Lamellenebene E rechtwinkeliger unterer Hakensteg 26 gegenübersteht. Der untere Hakensteg 26 ist einends mit einen zur Rolladeninnenfläche 11 parallelen Ansatzstück 28 sowie andernends mit einer nach unten einwärts gekrümmten Rinnenkante 30 ausgestattet, und er ragt um ein Kragmaß a-- von hier etwa 16 mm -- von der Rolladeninnenfläche 11 ab. Zwischen dieser und dem Ansatzstück 28 verläuft eine an die Abwinkelung 20 angeformte Leiste 32.The upper hinge part 14 of the lamella 12, which is upper in FIG. 1, comprises - seen in cross-section - a bend 20, one of this upwardly directed curve piece 22 with outgoing from the end, to the plane E of the blade 12 slightly inclined hooked web 24, the downward free edge 25 facing a likewise projecting from the bend 20, the slat plane E rectangular lower hook web 26 faces. The lower hook web 26 is at one end equipped with a parallel to the shutter inner surface 11 extension piece 28 and the other end with a downwardly inwardly curved gutter edge 30, and he projects by a Kragmaß a-- from here approximately 16 mm - from the inner surface 11 of the roller shutter. Between this and the extension piece 28 is formed on the bend 20 molded bar 32nd

Das mit der anderen Längsseite der Lamelle 12 einstückige Gegengelenkteil 16 besteht aus einer nach unten offenen Rinne 34 teilkreisförmigen Querschnitts mit einem anschließenden, zur Rolladeninnenfläche 11 geneigt gerichteten geraden Rinnenschenkel 35, dessen freies Schenkelende 36 einen rinnenartigen Sitz 37 für die freie Kante 25 des oberen Hakenstegs 24 der nach unten hin folgenden Lamelle 12 anbietet. Beim Verschwenken der Lamellen 12 gegeneinander dient der gerade Rinnenschenkel 35 zur Wegbegrenzung; er bildet einen Anchlag für den unteren Hakensteg 26. Im übrigen liegt dem freien Rinnenende 36 eine zu ihm weisende Nasenleiste 38 gegenüber.The one-piece with the other longitudinal side of the blade 12 counter-joint part 16 consists of a downwardly open channel 34 part-circular cross-section with a subsequent, the roller shutter inner surface 11 inclined straight trough legs 35, the free leg end 36 a trough-like seat 37 for the free edge 25 of the upper hook web 24 of the subsequent downward slat 12 offers. When pivoting the slats 12 against each other, the straight gutter leg 35 serves to limit travel; he forms an Anchlag for the lower hook web 26. Moreover, the free end of the trough 36 is facing a leading edge 38 facing him.

Die beiden Gelenkteile 14, 16 der beiden benachbarten Lamellen 12 sind unter Zwischenschaltung eines seinerseits rinnenartigen Kunststoffprofils 40 ineinandergeschoben. Das in Fig. 8 erkennbare Kunststoffprofil 40 liegt mit einem querschnittlich L-förmigen Wandabschnitt 42 dem oberen Hakensteg 24 außenseitig an und untergreift mit seinem unteren kurzen Schenkel 43 die freie Kante 25 des Hakenstegs 24. Der Wandabschnitt 42 geht in einen -- querschnittlich einem Viertelkreis entsprechenden -- gekrümmten Rohrflächenabschnitt 44 über, von dem eine angeformte Rippe 46 aufragt. Der Rohrflächenabschnitt 44 bietet außenseitig eine von zwei Wülsten 47 begrenzte Aufnahmenut 48 für die Nasenleiste 38 des auf das Kunststoffprofil 40 aufzusetzende Gegengelenkteiles 16 an.The two joint parts 14, 16 of the two adjacent lamellae 12 are pushed together with the interposition of a groove-like plastic profile 40 on its part. The recognizable in Fig. 8 plastic profile 40 is located with a cross-sectionally L-shaped wall portion 42 of the upper hook web 24 on the outside and engages with its lower short leg 43, the free edge 25 of the hook web 24. The wall portion 42 goes into a - cross-section a quarter circle corresponding curved tube surface portion 44, from which a molded-on rib 46 rises. The tube surface portion 44 provides on the outside a limited by two beads 47 receiving groove 48 for the Leading edge 38 of the aufzusetzende on the plastic profile 40 counter-joint part 16 at.

Die Höhe h der Sicht- oder Außenfläche 50 der Lamelle 12 misst hier etwa 70 mm, der Abstand q zwischen der freien Kante 25 des oberen Gelenkteils 14 mit dem freien Rinnenende 36 des unteren Gegengelenkteils 16 etwa 73 mm. Der Außenradius r des an die Rolladeninnenfläche 11 anschließenden querschnittlich gekrümmten Rinnenabschnitts 34 um den Mittelpunkt M der Kontur des seinerseits rinnenartigen Sitzes 37 beträgt etwa 10 mm, die Kraglänge i der Nasenleiste 38 hier 1 mm; diese entspricht damit etwa der Profildicke e von 0,8 mm. Von der Außenseite des Rinnenabschnitts 34 ragen parallel zur Rolladeninnenfläche 11 zum einen ein Paar von Lagerleisten 52 auf sowie zum anderen eine einwärts geneigte äußere Kammleiste 54.The height h of the visible or outer surface 50 of the lamella 12 here measures about 70 mm, the distance q between the free edge 25 of the upper joint part 14 with the free groove end 36 of the lower counter-joint part 16 about 73 mm. The outer radius r of the adjoining the roller shutter inner surface 11 cross-sectionally curved channel portion 34 about the center M of the contour of the trough-like seat 37 is about 10 mm, the Kraglänge i the nose strip 38 here 1 mm; this corresponds approximately to the profile thickness e of 0.8 mm. From the outside of the channel section 34 protrude parallel to the roller shutter inner surface 11 on the one hand, a pair of bearing strips 52 and on the other an inwardly inclined outer comb strip 54th

Die Sichtfläche 50 der Lamelle 12 ist in fünf Längsfelder 60 der Breite b von 10 mm sowie zwei Außenfelder 62 geringfügig größerer Breite b1 unterteilt. In der Ausführung nach Fig. 1,2 ist -- unter Bildung paralleler Kammlinien 64 als Feldbegrenzung -- die Oberflächenkontur von jedem der Längs- bzw. Außenfelder 60, 62 im Querschnitt konkav ausgebildet; von Kammlinie 64 zu Kammlinie 64 verläuft eine einem einzigen Radius R zugeordnete Oberflächenkontur 66, deren -- in Fig. 2 überhöht wiedergegebener -- maximaler Abstand n zu einer durch die Kammlinien 64 bestimmten Ebene K zwischen 0,1 mm und 0,3 mm beträgt, insbesondere 0,15 mm. Ein von den Querschnittsschenkeln der gratartigen Kammlinie 64 begrenzter Querschnitts- oder Kammwinkel w liegt zwischen 170° und 179°, in der dargestellten Ausgestaltung bei 177°.The visible surface 50 of the lamella 12 is subdivided into five longitudinal fields 60 of width b of 10 mm and two outer fields 62 of slightly greater width b 1 . In the embodiment according to FIG. 1, 2-the formation of parallel ridge lines 64 as field boundary-the surface contour of each of the longitudinal or outer fields 60, 62 is concave in cross-section; from ridge line 64 to ridge line 64 extends a single radius R associated surface contour 66 whose - in Fig. 2 excessive reproduced - maximum distance n to a determined by the ridge lines 64 level K is between 0.1 mm and 0.3 mm , in particular 0.15 mm. A cross-sectional or comb angle w limited by the cross-sectional limbs of the ridge-like ridge line 64 lies between 170 ° and 179 °, in the illustrated embodiment at 177 °.

In Fig. 3 setzt sich -- in einer anderen Ausgestaltung -- die Oberflächenkontur eines mittleren Abschnittes 66a des Radius R beidseits mit jeweils einem Außenabschnitt 66b der Breite f geringerer Neigung -- Radius R1 -- zur Ebene K fort. Auch hier ist die Gesamttiefe mit n bezeichnet.In Fig. 3 is set - in another embodiment - the surface contour of a central portion 66 a of the radius R on both sides, each with an outer portion 66 b of the width f lesser inclination - radius R 1 - to the plane K on. Again, the total depth is denoted by n.

Bei einer weiteren Ausführungsform nach Fig. 4 sind statt der Kammlinien eingesenkte Tallinien 68 als Begrenzung der Längsfelder 60, 62 vorgehen, d. h. die gekrümmte Oberflächenkontur 70 ist hier konvex mit einer maximalen Höhe n1 über der von den Tallinien 68 bestimmten Ebene K, deren Maß jenem der/des zu den anderen Beispielen bezifferten Tiefe bzw. Abstandes n entspricht. Das Maß des hier als Öffnungswinkel bezeichenbaren Querschnittswinkels t liegt ebenfalls in dem oben bezifferten Bereich.In a further embodiment according to FIG. 4, valley lines 68 recessed instead of the ridgelines are used as boundaries of the longitudinal fields 60, 62, ie the curved surface contour 70 is convex here with a maximum height n 1 above the plane K determined by the vertical lines 68, whose dimension that corresponds to the depth or distance n given to the other examples. The extent of the cross-sectional angle t, which can be designated here as the opening angle, is also in the range indicated above.

Auch die konvexe Oberflächenkontur 70 kann sich -- wie zu Fig. 3 erläutert -- aus drei Teilbereichen zusammensetzen.Also, the convex surface contour 70 can - as explained for Fig. 3 - composed of three sub-areas.
