Abstract

In a Roman blind, the upper edge of the pleats (9) is connected to a supporting rail (8) which can be raised and lowered in the closing and opening direction. The supporting rail (8) and the pleats (9) have holes (10) at a distance form each lateral boundary of the shaded area formed by the pleats (9). Supporting cords (11) are threaded through the holes (10) and clamped inside a frame (1, 2, 3) surrounding the shaded area to stabilize horizontally the pleats (9). When at least one of the boundaries of the shaded area is inclined to another boundary, a tensioning cord (13) with the same inclination is associated with the inclined boundary. One end of this tensioning cord (13) is connected to the supporting rail (8) and the other end to a roller tensioning device (12) which is fixed inside the frame (1, 2, 3).

FaltjalousiePleated blind
Die Erfindung betrifft eine Faltjalousie, bei der die, deren oberen Rand bildende Faltlamelle mit einer, in der Schließ- und Öffnungsrichtung bewegbaren Tragleiste verbunden ist, und die Tragleiste und die Faltlamellen mit Abstand von dem jeweiligen seitlichen Begrenzungsrand des von den Faltlamellen gebildeten Beschattungsfeldes angeordnete Lochungen, für durch diese hindurchgeführte, in einen, in das Beschattungsfeld um¬ fassenden Rahmen eingespannte Tragsaiten zur Flächenstabili¬ sierung der Faltlamellen aufweisen.The invention relates to a folding blind in which the folding lamella, the upper edge of which is connected to a support bar movable in the closing and opening direction, and the supporting bar and the folding lamellae arranged at a distance from the respective lateral boundary edge of the shading field formed by the folding lamellae , for carrying strings passed through it and clamped in a frame encompassing the shading field for surface stabilization of the folding slats.
Die Anwendung von Faltjalousien dieser Gattung bringt Schwie¬ ligkeiten mit sich, wenn die von den Faltjalousien zu binden¬ den Beschattungsfeider für Rahmen bestimmt sein sollen, bei denen die Rahmenleisten spitz- oder stumpfwinklig zueinander verlaufen, wie dies in modernen Bauwerken, z.B. bei verglas¬ ten Wintergärten usw. häufig der Fall ist. Diese Schwierig¬ keiten ergeben sich aus dem konstruktiven Zwang, daß die orts¬ fest in den Rahmen eingespannten Tragsaiten mit ihrer Spann¬ richtung in Richtung der öffnungs- und Schließbewegung verlau¬ fen müssen, weil die Tragleiste der Faltlamellen und die Falt¬ lamellen selbst mit ihren Lochungen von den Tragsaiten zwangs¬ geführt sind.The use of folding blinds of this type creates difficulties when the shading fields to be bound by the folding blinds are intended for frames in which the frame strips run at an acute or obtuse angle to one another, as is the case in modern buildings, e.g. is often the case with glazed conservatories etc. These difficulties arise from the constructive constraint that the strings fixed in the frame must run with their tensioning direction in the direction of the opening and closing movement, because the support strip of the folding slats and the folding slats themselves their perforations are positively guided by the supporting strings.
Der Erfindung liegt die Aufgabe zugrunde, die gattungsgemäßen Faltjalousien so zu verbessern, daß auch die Bildung von Be¬ schattungsfeldern möglich gemacht wird, deren Begrenzungsrän¬ der nicht rechtwinklig, sondern auch geneigt zueinander ver¬ laufen. Diese Aufgabe wird dadurch gelöst, daß bei geneigtem Verlauf mindestens eines der Begrenzungsränder des Beschattungsfeldes zu einem anderen, die, dem geneigten Begrenzungsrand zugeord¬ nete, entsprechend geneigt ausgerichtete Saite, als Spannsaite einerseits mit der Tragleiste und andererseits mit einer orts¬ fest in dem Rahmen angeordneten Roll-Spanneinrichtung verbun¬ den ist.The invention is based on the object of improving the generic folding blinds in such a way that the formation of shading fields is also made possible, the boundary edges of which do not run at right angles but also at an angle to one another. This object is achieved in that, in the case of an inclined course, at least one of the boundary edges of the shading field to another, the correspondingly inclined string associated with the inclined boundary edge, as a tension string on the one hand with the supporting strip and on the other hand with a fixed in the frame arranged roll tensioning device is connected.
Mit dieser Ausbildung einer FaltJalousie wird erreicht, daß sich auch der Bereich der Faltlamellen, deren Außenkanten den geneigt verlaufenden Begrenzungsrand bilden, die also entspre¬ chend der Neigung schräg abgeschnittem sind, durch eine Saite flächenstabilisieren läßt. Diese Saite paßt sich dabei der öffnungs- und Schließbewegung in der Weise an, daß sie aus ihrer Neigungsposition in der Schließstellung der FaltJalou¬ sie während deren Öffnungsbewegung in eine Position in einem etwa rechten Winkel zu der anderen (Trag-)Saite ändert und sich dabei unter bestehenbleibender Spannung verkürzt.With this design of a folding blind it is achieved that the area of the folding lamellae, the outer edges of which form the inclined boundary edge, which are accordingly cut obliquely according to the inclination, can be surface stabilized by a string. This string adapts to the opening and closing movement in such a way that it changes from its inclined position in the closed position of the folding blind during its opening movement to a position at an approximately right angle to the other (supporting) string and thereby changes shortened while maintaining tension.
Bei einer Faltjalousie mit einer Tragleiste, die mit einem ku- lissengeführten, heb- und senkbar antreibbaren Tragschlitten verbunden ist, können die Tragleisten erfindungsgemäß einsei¬ tig in den oberen Begrenzungsrand des Beschattungsfeldes aus¬ kragen, und die geneigt ausgerichtete, mit einer Roll-Spannein¬ richtung verbundene Spannsaite an dem Auskragende der Traglei- ste befestigt sein.In the case of a folding blind with a support bar, which is connected to a slide, which can be driven and lifted and lowered, the support bars according to the invention can protrude on one side into the upper boundary edge of the shading area, and the inclined ones with a roll tensioning device ¬ tension strings connected to the cantilever end of the support bar.
Weitere Merkmale der Erfindung sind in Unteransprüchen nieder¬ gelegt.Further features of the invention are laid down in subclaims.
Anhand der in der Zeichnung dargestellten Ausführungsbeispiele wird die Erfindung näher erläutert. In der Zeichnung zeigen:The invention is explained in more detail using the exemplary embodiments shown in the drawing. The drawing shows:
Fig. 1 eine FaltJalousie mit rechteckigem Beschattungsfeld, Fig. 2 eine FaltJalousie mit einem Beschattungsfeld in der Form eines gleichschenkligen Dreiecks, und1 is a folding blind with a rectangular shading field, Fig. 2 is a pleated blind with a shading field in the form of an isosceles triangle, and
Fig. 3 eine Faltjalousie mit einem Beschattungsfeld in der Form eines, auf einem Rechteck aufstehenden recht¬ winkligen Dreiecks; alle Darstellungen schematisch.3 shows a folding blind with a shading field in the form of a right-angled triangle standing on a rectangle; all representations schematically.
Fig. 1 zeigt einen Rahmen, der ein Beschattungsfeld in der Form eines rechtwinkligen Dreiecks erfordert. In der strich¬ punktiert angedeuteten Rahmenleiste 1 mit, nicht dargestell¬ tem U-Profil, ist ein, aus Motor 4, Antriebsscheibe 5, Umlenk¬ scheibe 6, und Zahnriemen 7 gebildeten, reversierbarer Riemen¬ trieb angeordnet. Mit dem Zahnriemen 7 ist die Tragleiste 8 fest verbunden, die in das Beschattungsfeld kragt, dessen Be¬ grenzungsränder von Rahmenleisten 1, 2 und 3 gebildet werden. Unter der Tragleiste 8 ist ortsfest die oberste Faltlamelle 9a der Faltlamellen 9 der FaltJalousie befestigt. Die Tragleiste 8 und alle Faltlamellen 9 weisen in der gezeichneten Stellung senkrecht übereinander angeordnete Lochungen 1+ auf, durch die eine, parallel zur Rahmenleiste 1 verlaufende Tragsaite 11 hindurchgeführt und oben und unten fest in den Rahmen einge¬ spannt ist. In der rechtwinklig zur Rahmenleiste 1 liegenden Rahmenleiste 2 ist unterhalb des Endes der anschließenden Rah¬ menleiste 3 eine Roll-Spanneinrichtung 12 ortsfest angeordnet, und die mit dieser verbundene Spannsaite 13 ist durch weitere Lochungen 14 in den Faltlamellen 9 geführt, die, gegeneinander versetzt, auf einer Linie liegen, die parallel zu dem geneigten, durch die Rahmenleiste 3 gebildeten Begrenzungsrand verläuft. Das Ende dieser Spannsaite 13 ist fest mit dem Auskragende 8a der Tragleiste 8 verbunden.Fig. 1 shows a frame that requires a shading field in the form of a right triangle. A reversible belt drive formed from the motor 4, drive pulley 5, deflection pulley 6 and toothed belt 7 is arranged in the dash-dotted frame bar 1 with a U-profile (not shown). The support strip 8, which projects into the shading field, the boundary edges of which are formed by frame strips 1, 2 and 3, is firmly connected to the toothed belt 7. The uppermost folding lamella 9a of the folding lamellae 9 of the folding blind is fixed in place under the support strip 8. In the position shown, the support strip 8 and all the folding slats 9 have perforations 1+ arranged vertically one above the other, through which a support string 11, which runs parallel to the frame strip 1, is guided and is firmly clamped at the top and bottom of the frame. In the frame bar 2 lying at right angles to the frame bar 1, a roll tensioning device 12 is arranged in a stationary manner below the end of the adjoining frame bar 3, and the tensioning string 13 connected to this is guided through further perforations 14 in the folding slats 9, which, offset from one another, lie on a line which runs parallel to the inclined boundary edge formed by the frame strip 3. The end of this tension string 13 is fixedly connected to the projecting end 8a of the support bar 8.
Bei der aufwärts gerichteten Schließbewegung der FaltJalousie bewegt sich die Tragleiste 8, angetrieben durch den Zahnriemen 7 in Richtung des Pfeils S und nimmt dabei die Faltlamellen 9 der Faltjalousie, geführt in der Tragsaite 11 und traggeführt von der Spannsaite 13 mit, wobei die Roll-Spanneinrichtung 12 den Gegenzug ausübt. Bei der abwärts gerichteten Öffnungsbe- - H - wegung hält diese Roll-Spanneinrichtung 12 den Zug aufrecht und damit auch die Tragführung der Faltlamellen 9.During the upward closing movement of the folding blind, the support strip 8, driven by the toothed belt 7 in the direction of arrow S, takes the folding slats 9 of the folding blind, guided in the supporting string 11 and supported by the tensioning string 13, with the roll tensioning device 12 exercises the return. With the downward opening - H - movement, this roll tensioning device 12 maintains the train and thus also the load-bearing guide of the folding slats 9.
Das von der FaltJalousie nach Fig. 2 gebildete Beschattungs¬ feld in der Form eines gleichschenkligen Dreiecks erfordert eine Tragleiste 18, deren Abmaß etwa der Schnittlänge ent¬ spricht, die sich beim Abschneiden der Spitze des gleichschenk¬ ligen Dreiecks ergibt. Die Tragleiste 18 ist mittig an ihrer Unterseite mit einem Ende 22b einer Treibseite 22 verbunden, die in Richtung der Winkelhalbierenden durch die Mitte des Be- schattungsfeldes zu dessen Grundlinie und von dort durch eine Rohrführung 23 rechtwinklig abgebogen, bis zu einer der unte¬ ren Dreieckecken, dort in die Richtung des Dreieckschenkels er¬ neut abgebogen, bis zu einer Umlenkrolle 24 an der Dreieck¬ spitze geführt und um diese herumgeleitet, an der Oberseite der Tragleiste 18 befestigt ist. Die Treibsaite 22 ist mit dem Zahnriemen 7 eines, entlang des einen Dreieckschenkels ange¬ ordneten und parallel in dessen Richtung transportierenden Riementriebes 4, 5, 6, 7 entsprechend der Ausbildung nach Fig. 1 verknüpft, und die Tragleiste 18 an beiden Enden 18a und 18b jeweils mit den Spannsaiten 25, 26 von, im Bereich der beiden unteren Dreiecks-Ecken angeordneten Roll-Spanneinrichtungen 27, 28 verbunden. Zwischen jede der beiden Rahmenleisten 1 und 2 und die Rahmenleiste 3 sind parallel zur Winkelhalbierenden verlaufende Tragsaiten 21a, 21b gespannt. Die Tragleiste 18 wird bei Bewegung des Zahnriemens 7 in Richtung des Pfeils S aus der gezeichneten Schließstellung der FaltJalousie über die Treibsaite 22 nach unten bewegt, und diese dabei von den, un¬ ter Zug stehenden Sapnnsaiten 25, 26 und den Tragsaiten 21a, 21b seitlich flächenstabilisiert. Die Schließbewegung wird durch Umkehr der Antriebsrichtung des Zahnriemens 7 eingelei¬ tet und beendet.The shading field formed by the folding blind according to FIG. 2 in the form of an isosceles triangle requires a support strip 18, the dimensions of which correspond approximately to the cutting length which results when the tip of the isosceles triangle is cut off. The support strip 18 is connected in the center on its underside to an end 22b of a drive side 22 which is bent at right angles in the direction of the bisector through the center of the shading area to its base line and from there through a pipe guide 23 to one of the lower triangular corners , there again bent in the direction of the triangle leg, guided up to a deflection roller 24 at the triangle tip and guided around it, attached to the top of the support strip 18. The drive string 22 is linked to the toothed belt 7 of a belt drive 4, 5, 6, 7 arranged along the one triangular leg and transporting it parallel in the direction thereof in accordance with the design according to FIG. 1, and the support strip 18 at both ends 18a and 18b each connected to the tension strings 25, 26 of roll tensioning devices 27, 28 arranged in the region of the two lower triangular corners. Between each of the two frame strips 1 and 2 and the frame strip 3 are parallel strings 21a, 21b stretched parallel to the bisector. When the toothed belt 7 moves in the direction of arrow S, the support strip 18 is moved downward from the drawn closed position of the folding blind via the driving strings 22, and this laterally from the tension straps 25, 26 and the strings 21a, 21b which are under tension area stabilized. The closing movement is initiated and ended by reversing the drive direction of the toothed belt 7.
Bei der Faltjalousie in der Form eines, auf einem Rechteck aufstehenden rechtwinkligen Dreiecks nach Fig. 3 wird die, wie bei der Ausbildung nach Fig. 1 in das Beschattungsfeld aus- kragende Tragleiste 8 vom Zahnriemen 7 eines Riementriebes 4, 5, 6, 7 parallel entlang, nicht nur der der Dreiecks¬ kathete, sondern auch der an diese anschließenden Rechteck¬ seite bis an die untere Ecke des Rechtecks geführt. Eine, der Breite des Rechtecks entsprechende Hubleiste 38 ist ober- und unterhalb ihrer beiden Enden wechselseitig von einem Mit¬ nehmerelement 39 beaufschlagbar, das auf dem Zahnriemen 37 eines Riementriebes 34, 35, 36, 37 angeordnet ist, der an der gegenüberliegenden Rechteckseite angeordnet ist und pa¬ rallel zu dieser führt. Das andere Ende der Hubleiste 38 ist auf der anderen Rechteckseite gleitend geführt und mit einer, mit Umführrollen um den gesamten Umfang des Beschattungsfel¬ des geführten Umlauftreibsaite 40 verbunden, die sich jeweils am, dem Mitnehmerelement 39 gegenüberliegenden Umlaufende des Riementriebes 34, 35, 36, 37 befindet. Die am Auskragende 8a der Tragleiste 8 befestigte Spannsaite 13 verläuft von dort pa¬ rallel zur Hypotenusenseite des Dreiecks und wird an deren un¬ terem Ende, im Bereich des Übergangs zu der anschließenden Rechteckseite über ein Umlenkstück 41 an der Hubleiste 38 zur unteren Rechteckecke und um diese herum zur Roll-Spanneinrich¬ tung 12 geführt.In the case of the folding blind in the form of a right-angled triangle standing on a rectangle according to FIG. 3, as in the embodiment according to FIG. 1, it is extended into the shading field. projecting support bar 8 from the toothed belt 7 of a belt drive 4, 5, 6, 7 parallel along, not only that of the triangular catheter, but also the adjoining side of the rectangle to the lower corner of the rectangle. A lifting bar 38 corresponding to the width of the rectangle can be acted upon alternately above and below its two ends by a driving element 39 which is arranged on the toothed belt 37 of a belt drive 34, 35, 36, 37 which is arranged on the opposite side of the rectangle and leads parallel to this. The other end of the lifting bar 38 is slidably guided on the other side of the rectangle and connected to a recirculating drive string 40, which is guided with guide rollers around the entire circumference of the shading field and which is located on the circumferential end of the belt drive 34, 35, 36, opposite the driving element 39. 37 is located. The tension string 13 fastened to the cantilever end 8a of the support bar 8 runs from there parallel to the hypotenuse side of the triangle and is at its lower end, in the area of the transition to the adjoining rectangle side, via a deflection piece 41 on the lifting bar 38 to the lower rectangle corner and around this led around to the roll tensioning device 12.
Bei Einleitung des Öffnungsvorgangs der geschlossenen Faltja¬ lousie bewegt der Zahnriemen 37 die Tragleiste 8 mit dem dar¬ unter befindlichen Faltlamellen 9, wie bei der Ausbildung nach Fig. 1, nach unten in Richtung des Pfeils S, und die Spannsaite 13 folgt dieser Bewegung entsprechend unter Zug. Gleichzeitig beaufschlagt das Mitnehmerelement 39 das eine Ende der Hublei¬ ste 38 im Absenksinne, während die Umlauftreibsaite 40 das an¬ dere Ende ebenfalls nach unten bewwgt. Tragleiste 8 und Hub¬ leiste 38 erreichen so gemeinsam ihre untere Endstellung, bei der die Faltjalousie voll geöffnet ist. Der Schließvorgang läuft sinngemäß, umgekehrt ab, d.h. die Tragleiste 8 wird vom Zahnriemen 37 nach oben bewegt und gleichzeitig wird die Hub¬ leiste 38 vom Mitnehmerelernent 39 des Zahnriemens 37 und von der Umlauftreibsaite 40 angehoben, bis die jeweilige obere Endstellung erreicht ist. When the opening process of the closed folding blind is initiated, the toothed belt 37 moves the support strip 8 with the folding slats 9 located underneath, as in the embodiment according to FIG. 1, downward in the direction of the arrow S, and the tensioning string 13 follows this movement accordingly under train. At the same time, the driver element 39 acts on one end of the lifting bar 38 in the lowering direction, while the recirculating drive string 40 also moves the other end downward. Carrier bar 8 and lifting bar 38 thus jointly reach their lower end position, in which the folding blind is fully open. The closing process is analogous, vice versa, i.e. the support bar 8 is moved upwards by the toothed belt 37 and at the same time the lifting bar 38 is lifted by the driving element 39 of the toothed belt 37 and by the circulation drive string 40 until the respective upper end position is reached.
