Description

Gegenstand der vorliegenden Erfindung ist ein Rafflamellenstore gemäss Oberbegriff des Patentanspruches 1.The present invention relates to a roman blinds according to the preamble of claim 1.

Bei Lamellenstores dieser Gattung, bei denen die Lage der Lamellen mittels seitlich in Führungsschienen untergebrachten faltbaren Vertikalverbindungen (z.B. Glieder- oder Gelenkketten) einstellbar ist, ist der Neigungswinkel während des Absenkens oder Anhebens werkseitig vorgegeben. Eine nachträgliche Aenderung und Einstellung des Neigungswinkels des Stores am Bau ist bei der bekannten Rafflamellenstore nicht möglich.In the case of slat stores of this type, where the position of the slats can be adjusted by means of foldable vertical connections (e.g. link or link chains) accommodated on the side in guide rails, the angle of inclination during lowering or lifting is preset at the factory. A subsequent change and adjustment of the inclination angle of the store on the building is not possible with the known Roman blind.

Ein solcher Store ist aus der CH-A-635164 und aus der CH-A-503885 bekannt.Such a store is known from CH-A-635164 and from CH-A-503885.

Es sind auch Stores bekaut, (CH-A-371360), bei denen die Lamellen bei Drehrichtungsänderung der Aufzugswelle durch Klinken, die mit einem Zahnkranz kämmen, geschwenkt werden können. Beim Absenken und Aufziehen des Stores sind die Klinken ausser Eingriff mit dem Zahnkranz und die Lamellen befinden sich in vertikaler Stellung. Dadurch wird der hinter dem Store liegende Raum bei Betätigung des Stores immer abgedunkelt.There are also chewed stores (CH-A-371360), in which the slats can be pivoted when the direction of rotation of the elevator shaft changes by means of pawls that mesh with a ring gear. When lowering and opening the store, the pawls are out of engagement with the ring gear and the slats are in a vertical position. As a result, the space behind the store is always darkened when the store is operated.

Hier will die Erfindung Abhilfe schaffen.The invention seeks to remedy this.

Die Erfindung, wie sie in Anspruch 1 gekennzeichnet ist, löst die Aufgabe, ein Store zu schaffen, bei dem mit einfachen Mitteln der Neigungswinkel der Lamellen in der Absenkphase an die örtlichen Gegebenheiten (Südfassade, West- oder Ostfassade, etc.) oder je nach Benutzungsart des Raumes (z.B. Arbeitsraum mit Bildschirmgeräten etc.) angepasst und, falls nötig, auch nachträglich geändert werden kann.The invention, as characterized in claim 1, solves the task of creating a store in which, with simple means, the angle of inclination of the slats in the lowering phase to the local conditions (south facade, west or east facade, etc.) or depending The type of use of the room (e.g. work room with screen devices, etc.) can be adapted and, if necessary, changed later.

Der wesentliche Vorteil der Erfindung besteht darin, dass der Neigungswinkel ohne Demontage der Aufzugsvorrichtung verstellt und auch nachträglich an die Gegebenheiten der Lage des Stores und der Benützungsart des dahinterliegenden Raumes angepasst werden kann.The main advantage of the invention is that the angle of inclination can be adjusted without dismantling the elevator device and can also be subsequently adapted to the conditions of the location of the store and the type of use of the space behind it.

Ein weiterer Vorteil liegt darin, dass dank der im Antrieb eingebauten Feder nach dem vollständigen Absenken des Stores die Antriebswelle weitergedreht werden kann, ohne dass das Antriebsrad mitdreht. Dies ermöglicht insbesondere bei Elektroantrieb Abstellungsungenauigkeiten auszugleichen und beim Verschwenken der Lamellen in der untersten Position zu verhinde n, dass während des Schwenkens bereits eine Vertikalbewegung erfolgt, die einen Spalt zwischen der untersten Lamelle und dem Sims hervorrufen würde.Another advantage is that, thanks to the spring built into the drive, the drive shaft can be rotated further after the store has been completely lowered without the drive wheel turning too. This makes it possible to compensate for inaccuracies in parking, in particular in the case of an electric drive, and to prevent the slats in the lowest position from pivoting, so that a vertical movement already takes place during the pivoting, which would cause a gap between the lowest slat and the ledge.

In Figur 1 sind zum besseren Verständnis der Erfindung die wichtigsten, in der Seitenführung 1 und in der darüber angeordneten, in einem Gehäuse 3 untergebrachten Aufzugs- und Verstellmechanik zum Heben, Senken und Verschwenken der Lamellen 5 des Stores 7 dargestellt.For better understanding of the invention, FIG. 1 shows the most important elevator and adjustment mechanisms for lifting, lowering and pivoting the slats 5 of the store 7, which are arranged in the side guide 1 and in the above them, accommodated in a housing 3.

Im Gehäuse 3 der Aufzugsmechanik ist auf einer Welle 9, welche die beiden Seitenführungen 1 verbindet, ein Antriebs- und Umlenkrad 11 aufgesetzt. Das Antriebsrad 11 kann fest mit der Welle 9 verbunden sein, oder es kann zwischen der Welle 9 und dem Antriebsrad eine Kupplung eingesetzt sein, die zumindest in einer Richtung eine Drehbewegung der Welle 9 bezüglich des Antriebsrades 11 um beispielsweise einen Drehwinkel von 100 Grad ermöglicht, ohne dass eine Mitnahme erfolgt. Als Kupplungsglied kann eine schrauben- oder spiralförmig gewundene Feder 13 vorgesehen sein, deren eines Ende mit der Welle 9 und deren anderes Ende mit dem Antriebsrad 11 verbunden ist (Fig. 3). Über das Antriebsrad 11 läuft ein Zugorgan 15 in Gestalt eines gelochten Blechstreifens, eines Kunststoffbandes oder -seiles oder einer Gliederkette, an dessen einem Ende ein Rastglied 17 und an dessen anderem Ende ein Steuernocken 19 befestigt ist. Die Löcher oder Ausnehmungen 21 im Zugorgan 15 kommen auf der Peripherie des Antriebsrades 11 mit dort angebrachten Mitnehmern 23 in Eingriff. Im Gehäuse der Seitenführung 1 sind Nuten 25 eingelassen, die das Zugorgan 15 in gestreckter Lage und geringem Spiel aufnehmen können. Auf der Seite des Rastgliedes 17 befindet sich die Nut 25 vorzugsweise an einer Seitenfläche; auf der Seite des Steuernockens 19 liegt die Nut 25 vorzugsweise im wesentlichen in einem Winkel von ca. 45 Grad in der Ecke zwischen der Rückwand und der Seitenwand der Seitenführung 1. Damit das Zugorgan 15 nicht vom Antriebsrad 11 abgehoben werden kann, liegt in geringem Abstand zur Peripherie des Antriebsrades 11 ein Führungsblech 27. Anstelle eines Führungsbleches 27 kann selbstverständlich das Gehäuse 3, insbesondere wenn es aus Kunststoff gefertigt ist, selbst die Führung übernehmen.In the housing 3 of the elevator mechanism, a drive and deflection wheel 11 is placed on a shaft 9, which connects the two side guides 1. The drive wheel 11 can be fixedly connected to the shaft 9, or a coupling can be inserted between the shaft 9 and the drive wheel, which allows the shaft 9 to rotate in at least one direction with respect to the drive wheel 11 by, for example, a rotation angle of 100 degrees, without being taken along. A helically or helically wound spring 13 can be provided as the coupling member, one end of which is connected to the shaft 9 and the other end of which is connected to the drive wheel 11 (FIG. 3). About the drive wheel 11 runs a tension member 15 in the form of a perforated sheet metal strip, a plastic band or rope or a link chain, at one end of a locking member 17 and at the other end a control cam 19 is attached. The holes or recesses 21 in the tension member 15 engage on the periphery of the drive wheel 11 with drivers 23 attached there. In the housing of the side guide 1 there are grooves 25 which can accommodate the tension member 15 in the extended position and with little play. On the side of the locking member 17, the groove 25 is preferably on a side surface; on the side of the control cam 19, the groove 25 is preferably substantially at an angle of approximately 45 degrees in the corner between the rear wall and the side wall of the side guide 1. So that the traction element 15 cannot be lifted off the drive wheel 11, there is a short distance to the periphery of the drive wheel 11, a guide plate 27. Instead of a guide plate 27, the housing 3 can of course, especially if it is made of plastic is to take the lead yourself.

In der Seitenführung 1 ist weiter eine Führungsbahn 29 eingelassen, in der ein Gleitschuh oder eine Gleitrolle 31, die an einem Wagen 33 angebracht ist und diesen auf einer vertikal verlaufenden Bahn führt. Der Wagen 33 ist parallel zur Rückwand der Seitenführung angeordnet und besteht aus einem profilierten Blech oder aus Kunststoff und ist an einem Gliederkettenpaar 37 aufgehängt und in Betriebszustand am Rastglied 17 eingeklinkt. Das Gliederkettenpaar 37 bekannter Ausführung hängt an einer auf der Welle 9 schwenkbar angeordneten Wippe 39. Die Wippe 39 besteht aus zwei Armen 41, an denen die beiden Ketten des Gliederkettenpaares 37 mittels Seilen 35 befestigt sind. Neben der Wippe 39 ist auf der Welle 9 drehfest ein Bremszylinder 43 mit einer darauf schraubenlinienförmig aufgewundenen Feder 45 angeordnet. Die beiden Enden 47 der Feder 45 stehen radial nach aussen von der Bremszylinderoberfläche ab (Figur 3). Ein Mitnahmesegment 49, das Teil der Wippe 41 ist, ragt axial zwischen den beiden Enden 47 hindurch in eine Ausnehmung 51 in einer neben dem Bremszylinder 43 auf dem Bremszylinder 43 aufgesetzten Stufenscheibe 53. Die Stufenscheibe 53 ist drehbar auf der Welle 9 aufgesetzt und weist im unteren Bereich vier Stufen A, B, C und D und im oberen Bereich eine weitere entgegengesetzt ausgebildete Stufe E auf. Die Sprünge der einzelnen Stufen verlaufen vorzugsweise radial.In the side guide 1 there is also a guide track 29 in which a slide shoe or a slide roller 31, which is attached to a carriage 33 and guides it on a vertically running track. The carriage 33 is arranged parallel to the rear wall of the side guide and consists of a profiled sheet metal or of plastic and is suspended from a pair of link chains 37 and latched onto the latching link 17 in the operating state. The link chain pair 37 of known design hangs on a rocker 39 pivotably arranged on the shaft 9. The rocker 39 consists of two arms 41 to which the two chains of the link chain pair 37 are fastened by means of ropes 35. In addition to the rocker 39, a brake cylinder 43 with a spring 45 wound helically thereon is arranged on the shaft 9 in a rotationally fixed manner. The two ends 47 of the spring 45 project radially outward from the brake cylinder surface (FIG. 3). A driving segment 49, which is part of the rocker 41, projects axially between the two ends 47 into a recess 51 in a step plate 53 placed next to the brake cylinder 43 on the brake cylinder 43. The step plate 53 is rotatably mounted on the shaft 9 and has a lower area four levels A, B, C and D and in the upper area another opposite level E. The jumps in the individual stages preferably run radially.

An der rechten Seitenwand des Gehäuses 3 ist innen eine vertikal liegende Mehrkantwelle 55 drehbar gelagert gehalten, an deren unterem Ende ein erster radial abstehender Hebel 57 drehfest angebracht und auf deren oberem Teil ein ebenfalls radial abstehender Haltefinger 59 auf der Welle 55 vertikal verschiebbar aufgesetzt ist.On the right side wall of the housing 3, a vertically lying polygonal shaft 55 is rotatably supported on the inside, at the lower end of which a first radially projecting lever 57 is rotatably attached and on the upper part of which a likewise radially projecting retaining finger 59 is vertically slidably mounted on the shaft 55.

Der Haltefinger 59 gelangt in seiner höchstmöglichen Stellung (Figur 1) in Anlage mit der Stufe A der Stufenscheibe 53. Mit einer Schiebevorrichtung 61 kann der Haltefinger 59 abgesenkt werden, um entweder mit der Stufe B oder der Stufe C in Eingriff zu gelangen. Das Ende des Hebels 57 befindet sich neben der Nut 25, in der das Zugorgan 15 mit dem Steuernocken 19 geführt wird.In its highest possible position (FIG. 1), the holding finger 59 comes into contact with the step A of the step plate 53. The holding finger 59 can be lowered with a sliding device 61 in order to engage either step B or step C. The end of the lever 57 is located next to the groove 25, in which the tension member 15 is guided with the control cam 19.

Wenn sich der Steuernocken 19 in den Schwenkbereich des Hebels 57 einläuft, wird der Hebel 57 durch den Steuernocken 19 zusammen mit dem auf der Mehrkantwelle 55 sitzenden Haltefinger 59 verschwenkt. Bei dieser Verschwenkung kommt das Ende des Haltefingers 59 seitlich der Stufenscheibe 53 zu liegen und befindet sich nicht mehr im Eingriffbereich mit einer der Stufen A-C der Stufenscheibe 53.When the control cam 19 runs into the pivoting range of the lever 57, the lever 57 is pivoted by the control cam 19 together with the retaining finger 59 seated on the polygonal shaft 55. During this pivoting, the end of the holding finger 59 comes to lie to the side of the step plate 53 and is no longer in the engagement area with one of the steps A-C of the step plate 53.

Im Fahrweg der Stufe D auf der Stufenscheibe 53 liegt ein exzentrisch auf einem Drehknopf 63 angeordneter Anschlag 65. Der Drehknopf 63 ist in der Vorderseite der Seitenführung in einer Bohrung 67 gelagert. Anstelle eines exzentrischen Anschlages 65 können auch mehrere Bohrungen 66 in seitlichem Abstand angebracht sein, in die ein Anschlagstift einsteckbar und der Fahrweg der Stufenscheibe 53 begrenzbar ist.In the travel path of step D on the step plate 53 there is an abutment 65 arranged eccentrically on a rotary knob 63. The rotary knob 63 is mounted in a bore 67 in the front of the side guide. Instead of an eccentric stop 65, a plurality of bores 66 can also be made at a lateral distance, into which a stop pin can be inserted and the travel path of the stepped disk 53 can be limited.

Die Stufe E an der Stufenscheibe 53 gelangt in Anschlag mit einem ebenfalls auf der Vorderseite des Gehäuses der Seitenführung 1 angeordneten, in das Gehäuse 3 hineinragenden Anschlagstift 69. Der Anschlagstift 69 kann analog ausgebildet sein wie der Drehknopf 63 oder aus mehreren, auf einer Kreisbahn angeordneten Bohrungen 71 bestehen, in die jeweils ein Arretierstift einschiebbar ist, der die Drehbewegung der Stufenscheibe 53 einschränkt oder am Gehäuse 3 angegossen ist.The step E on the step plate 53 comes into abutment with a stop pin 69, also arranged on the front of the housing of the side guide 1 and projecting into the housing 3. The stop pin 69 can be designed analogously to the rotary knob 63 or can be arranged in a circular path from several Bores 71 exist, into each of which a locking pin can be inserted, which restricts the rotational movement of the stepped disk 53 or is cast onto the housing 3.

Im folgenden wird die Funktionsweise des erfindungsgemässen Rafflamellenstore näher erläutert.The mode of operation of the roman blind according to the invention is explained in more detail below.

In der Stellung gemäss Figur 4, wie sie beim Hochziehen der Lamellen 5 vorliegt, wird die Welle 9 durch einen am Ende der Welle 9 angreifenden Hand- oder Elektroantrieb im Uhrzeigersinn gedreht. Dabei gelangt die Kante E der Stufenscheibe 53 in Anlage mit dem Anschlagstift 69, der je nach gewünschtem Aufzugsneigungswinkel der Lamellen 5 in die entsprechende Bohrung 71 eingesteckt ist. Die Stufenscheibe 53 bleibt nun während des gesamten Aufziehvorganges in der vom Anschlag 69 gegebenen Position stehen. Mit der Stufenscheibe 53 ist auch die Wippe 39, die durch das Segment 49 mitgedreht worden ist, in eine Stellung, in der die Arme 41 im wesentlichen senkrecht zu Liegen kommen, gebracht worden. Die an den Armen 41 aufgehängten Gliederketten 37 halten die Lamellen 5 während des Aufziehens in der eingestellten Schräglage von beispielsweise 0, 15, 30 Grad oder einem anderen Neigungswinkel bis sie auf den von unten nach oben sich hebenden Stapel der Lamellen 5 abgelegt werden.In the position according to FIG. 4, as is the case when the slats 5 are pulled up, the shaft 9 is rotated clockwise by a manual or electric drive acting on the end of the shaft 9. The edge E of the stepped washer 53 comes into contact with the stop pin 69, which is inserted into the corresponding bore 71 depending on the desired elevator inclination angle of the slats 5. The stepped disc 53 now remains in the position given by the stop 69 during the entire mounting process. With the step plate 53, the rocker 39, which has been rotated by the segment 49, is in a position in which the arms 41 come to lie essentially perpendicular. The link chains 37 suspended from the arms 41 hold the slats 5 in the set inclined position of, for example, 0, 15, 30 degrees or another angle of inclination until they are placed on the stack of slats 5 which rises from the bottom up.

Beim Absenken der Lamellen 5 wird durch Drehen an der Handkurbel oder durch den Antriebsmotor die Welle 9 im Gegenuhrzeigersinn gedreht. Die satt auf dem drehfest mit der Welle 9 verbundenen Bremszylinder 43 aufliegende Feder 45 greift am Segment 49 an und dreht mit diesem sowohl die Wippe 39 als auch die Stufenscheibe 53 bis eine der Kanten C, B oder A in Anschlag mit dem Haltefinger 59 gelangt.When the slats 5 are lowered, the shaft 9 is rotated counterclockwise by turning the hand crank or by the drive motor. The spring 45, which rests firmly on the brake cylinder 43, which is non-rotatably connected to the shaft 9, engages the segment 49 and rotates with it both the rocker 39 and the stepped disk 53 until one of the edges C, B or A comes into contact with the holding finger 59.

Die Stellung der Stufenscheibe 53 in Figur 5 bewirkt einen Neigungswinkel der Lamellen 5 von ca. 30 Grad. Würde der Finger 59 durch die Schiebevorrichtung 61 derart eingestellt, dass er mit der Kante B in Eingriff käme, so würde sich ein Neigungswinkel von ca. 50 Grad einstellen (Figur 6) und bei Eingriff mit der Kante C ein Neigungswinkel von ca. 70 Grad (Figur 7).The position of the stepped disk 53 in FIG. 5 causes an angle of inclination of the slats 5 of approximately 30 degrees. If the finger 59 were set by the sliding device 61 in such a way that it would come into engagement with the edge B, then an angle of inclination of approximately 50 degrees would result (FIG. 6) and, when engaged with the edge C, an angle of inclination of approximately 70 degrees (Figure 7).

Sobald sich die unterste Lamelle 5 der tiefstmöglichen Stellung nähert, wird der Hebel 57 vom Steuernocken 19 geschwenkt. Durch diese Schwenkbewegung, die von der Mehrkantwelle 55 auf den Haltefinger 59 übertragen wird, schiebt sich Letzterer aus dem Kontaktbereich mit der Stufenscheibe 53, wodurch diese eine weitere Bewegung im Gegenuhrzeigersinn ausführen kann bis deren Kante D in Kontakt mit dem Anschlag 65 gelangt. In dieser Position befinden sich die Arme 41 der Wippe 39 wiederum annähernd in senkrechter Position und die am Gelenkkettenpaar 37 mittels den QuerhebeLn 38 verbundenen Lamellen 5 in vertikaler geschlossener Position.As soon as the lowest slat 5 approaches the lowest possible position, the lever 57 is pivoted by the control cam 19. This pivoting movement, which is transmitted from the polygonal shaft 55 to the retaining finger 59, pushes the latter out of the contact area with the stepped disk 53, as a result of which the latter can carry out a further counterclockwise movement until its edge D comes into contact with the stop 65. In this position, the arms 41 of the rocker 39 are again approximately in a vertical position and the slats 5 connected to the pair of link chains 37 by means of the transverse levers 38 are in the vertical closed position.

Um Ungenauigkeiten in der gesamten Vorrichtung ausgleichen zu können, welche verhindern, dass die einzelnen, übereinanderangeordneten Lamellen in Schliesslage sauber aneinanderliegen, kann der Anschlag 65 durch Drehen am Drehknopf 63 fein verstellt werden bis die Kanten der Lamellen 5 gegenseitig aufeinanderliegen.In order to be able to compensate for inaccuracies in the entire device, which prevent the individual slats arranged one above the other from lying against one another in the closed position, the stop 65 can be finely adjusted by turning the rotary knob 63 until the edges of the slats 5 lie on top of each other.

Dank der zwischen dem Antriebsrad 11 und der Welle 9 angeordneten Feder 13 kann die Welle 9 nach dem Ende der Absenkbewegung der Lamellen 5 um beispielsweise einen Betrag von bis 100 Grad weitergedreht werden, ohne dass dadurch in der Vorrichtung eine Beschädigung eintreten kann. Dies ermöglicht es, mit einfachen Endschaltern für motorische Antriebe zu arbeiten, bei denen die Endposition nicht sehr genau eingestellt werden muss. Im weiteren bewirkt die zusätzliche Drehung der Welle 9 nach dem vollständigen Absenken der Lamellen 5, dass beim Öffnen, d.h. beim Drehen der Welle 9 zum Anheben der Lamellen 5, letztere zuerst in die in Figur 4 beschriebene Position verschwenken bevor das Anheben der untersten Lamelle 5 beginnt.Thanks to the spring 13 arranged between the drive wheel 11 and the shaft 9, the shaft 9 can be rotated further, for example by an amount of up to 100 degrees, after the lowering movement of the lamellae 5, without this causing damage to the device. This makes it possible to work with simple limit switches for motor drives, in which the end position does not have to be set very precisely. Furthermore, the additional rotation of the shaft 9 after the slats 5 have been completely lowered means that when opening, i.e. when rotating the shaft 9 to raise the slats 5, first pivot the latter into the position described in FIG. 4 before the lowest slat 5 begins to be lifted.

Claims (9)

1. Laminated roller shutter (7) with a constant angle of inclination of the laminations (5) during the lowering of the shutter and a traction roller (15) arranged in lateral guides (1) for raising or lowering the shutter (7) with a horizontally lying driving shaft (9) arranged with a swivelling rocker (39) which is connected to a pair of chains (37) arranged in a lateral guide (1) for swivelling the laminations (5) characterized in that on the drive roller (9), a swivelling step pulley (53) is fitted on the latter carrying the rocker (39) connected with the step pulley (53) which has several limiting stops (A, B, C) which limit the angle of rotation of the chains (37) which can be brought into operation by means of an adjustable stop finger (59) fitted to swivel on the guide (1).
2. Laminated roller shutter according to Claim 1, characterized in that when the laminations (5) are completely lowered, the stop finger (59) can be swivelled out of the area of the step pulley (53) via a sequence switch cam (19) on the traction roller (15).
3. Laminated roller shutter according to Claim 1 or Claim 2, characterized in that the stops (A, B, C) consist of substantially radially running steps between segments with differing radii arranged on the periphery of the pulley (53).
4. Laminated roller shutter according to one of the Claims 1 or 2, characterized in that that the stop finger (59) is fastened on a multiple-cornered shaft (55) on which a swivelling arm (57) is fitted with a small clearance to the traction roller (15).
5. Laminated roller shutter according to on of the Claims 2 to 4, characterized in that the stop finger (59) can be moved axially on the multiple-cornered shaft through a sliding and stopping device (61) and can be stopped by this in predetermined positions of the stops A to C lying in the field of traverse.
6. Laminated roller shutter according to one of the Claims 1 to 5, characterized in that on the pulley (53) an additional step (E) is fitted in conjunction with an adjustable stop (69), which determines the angle of traverse of the rocker shaft (39) when the laminations (5) are raised.
7. Laminated roller shutter according to one of the Claims 2 to 6, characterized in that a step (D) is fitted on the pulley (53), which according to the swivelling of the stop finger (59), determines the angle of inclination of the closed laminations (5) in conjunction with a stop (65).
8. Laminated roller shutter according to Claim 7, characterized in that that the stop (65) is arranged to be adjustable for the compensation of irregularities in the traction mechanism and/or the laminations (5).
9. Laminated roller shutter according to one of the Claims 1 to 8, characterized in that the pulley (53) swivels on the brake cylinder (43) via a segment (49) fitted on the rocker shaft (39).
