Abstract

The draw and swivel device comprises at least two turning elements in the form of rocker discs (6,7) which are mounted on a common draw-up shaft (2). The turning area is restricted by end stops. A common locking slider (14) forms the intermediate stops. The ends (10-13) of the swivel members of an upper and lower blind area are attached to the rocker discs. By turning the discs the swivel members are raised on one side and lowered on the other causing swivel movement of all of the slats connected to the swivel members. The end stops for the two turning elements are arranged so that in one end position all slats of both areas are in the closed position and in the other end position all slats are in the fully opened positioned. The intermediate stop is arranged so that when the turning elements stop the slats of the upper blind are opened and the slats of the lower blind are partially closed. <IMAGE>

Description

Die Vorliegende Erfindung betrifft eine Raff- und Schwenkvorrichtung für Lamellenstoren mit Aufziehwelle, welche einen Spulenkörper für ein Aufzugsorgan des Lamellenstorenbehangs aufweist und ein auf der Aufziehwelle drehbares Wendeelement, an welchem die beiden Enden von Schwenkorganen für die Lamellen festgelegt sind und das eine zwischen der Aufziehwelle und dem Wendeelement reibschlüssig wirkende Kupplung sowie zwei Endanschläge zum Begrenzen des Wendebereiches des Wendeelementes resp. der Lamellen und einen dazwischen angeordneten, durch das Aufzugsorgan betätigten Zwischenanschlag aufweist, dessen Anschlagwirkung bei Vollständig abgesenktem Lamellenstorenbehang aufgehoben wird.The present invention relates to a gathering and swiveling device for slat blinds with a winding shaft, which has a bobbin for an elevator element of the slat blind curtain and a turning element that can be rotated on the winding shaft, on which the two ends of pivoting elements for the slats are fixed, and the one between the winding shaft and the turning element friction clutch and two end stops to limit the turning range of the turning element, respectively. of the slats and an intermediate stop arranged between them and actuated by the elevator element, the stop action of which is canceled when the slatted blind curtain is completely lowered.

Eine derartige Vorrichtung ist beispielsweise aus der DE 32 05 491 bekannt. Eine solche Vorrichung erlaubt es, die Lamellen des Lamellenbehanges in einer offenen, einer geschlossenen Stellung und einer Zwischenstellung durch ein einziges Betätigungsorgang für das Raffen des Lamellenbehanges, welches auf die Aufzugsachse einwirkt, zu fixieren. Dies wird mittels einem auf der Aufzugsachse angeordneten, mit dieser zwischen Anschlägen reibschlüssig verbundenem Wendeelement erreicht. Für den Zwischenanschlag ist ein Sperrschieber vorgesehen, welcher über ein Betätigungselement angesteuert wird.Such a device is known for example from DE 32 05 491. Such a device allows the slats of the slatted curtain to be fixed in an open, a closed position and an intermediate position by a single actuating operation for the gathering of the slatted curtain, which acts on the elevator axis. This is achieved by means of a turning element which is arranged on the elevator axis and is frictionally connected to it between stops. A locking slide is provided for the intermediate stop, which is controlled via an actuating element.

Die Aufgabe der Vorliegenden Erfindung bestand nun darin, eine solche bekannte Vorrichtung zum Raffen und Schwenken von Lamellenstoren dahingehend zu verbessern, dass sie für einen Storenbehang mit unterschiedlich einzustellenden Lamellenbereichen eingesetzt werden kann.The object of the present invention was to improve such a known device for gathering and swiveling slat blinds to the effect that it can be used for a blind curtain with slat areas to be set differently.

Diese Aufgabe wird erfindungsgemäss nach dem Kennzeichen von Anspruch 1 gelöst. Damit können vorteilhafterweise unter Beibehaltung eines einzigen Bedienorganes sowohl für den Raffwie auch für den Schwenkvorgang mehrere mit voneinander unabhängigen Lamellenausrichtungen versehenen Lamellenbereiche verschwenkt werden und in definierten Stellungen angehoben resp. abgesenkt werden.This object is achieved according to the characterizing part of claim 1. This can be advantageously both for the Raffwie while maintaining a single control element also for the pivoting process, several slat regions provided with mutually independent slat orientations are pivoted and raised or raised in defined positions. be lowered.

Vorzugsweise sind nach Anspruch 2 zwei Schwenkorgane für einen zweigeteilten Lamellenbehang vorgesehen. Derartige Lamellenbehange eignen sich speziell gut für die Beschattung von mit Bildschirmen ausgestatteten Arbeitsplätzen. Dabei soll die untere Behanghälfte die direkte Besonnung des Arbeitsplatzes verhindern, wofür die Lamellen in diesem Bereich zumindestens teilweise geschlossen sind, und die obere Behanghälfte möglichst viel Licht in den oberen Bereich des Arbeitsplatzes leiten um eine möglichst optimale natürliche Beleuchtung zu ermöglichen, wofür die Lamellen in diesem Bereich in einer annährend vollständig geöffneten Position ausgerichtet sind. Diese Lamellenstellungen werden erfindungsgemäss automatisch bereits beim Absenken des Behanges erstellt. Bei vollständig abgesenktem Lamellenbehang lassen sich die Lamellen aller Behangbereiche über den gesamten vorgesehenen Schwenkbereich mit dem einzigen Bedienorgan verschwenken.According to claim 2, two swivel members are preferably provided for a two-part slat curtain. Such slatted curtains are particularly well suited for shading workplaces equipped with screens. The lower half of the curtain should prevent direct exposure to the sun, for which the slats in this area are at least partially closed, and the upper half of the curtain should shine as much light as possible in the upper area of the work place to enable the best possible natural lighting, for which the slats in this area are aligned in an almost fully open position. According to the invention, these slat positions are automatically created when the curtain is lowered. When the slatted curtain is completely lowered, the slats of all curtain areas can be swiveled over the entire intended swivel range with the single control element.

Weitere bevorzugte Ausführungsformen der Erfindung sind in den Ansprüchen 3 bis 8 dargelegt.Further preferred embodiments of the invention are set out in claims 3 to 8.

Ein Ausführungsbeispiel der vorliegenden Erfindung wird nachstehend anhand von Zeichnungen noch näher erläutert. Es zeigen:

  • Fig. 1 schematisch den Schnitt durch eine erfindungsgemässe Vorrichtung bei teilweise abgesenktem Lamellenstoren;
  • Fig. 2 schematisch den Schnitt nach Figur 1 bei vollständig abgesenktem Lamellenstoren;
  • Fig. 3 schematisch die Lamellenstellungen der beiden Lamellenstorenbereiche in Aufziehstellung;
  • Fig. 4 die Darstellung nach Fig. 3 in Absenkstellung (Zwischenstellung);
  • Fig. 5 die Darstellung nach Fig. 3 in Schwenkstellung (Vollständig abgesenkt);
In das Gehäuse 1 der erfindungsgemässen Raff- und Schwenkvorrichtung ist die Aufziehwelle 2 des Lamellenstorens eingesteckt, wie aus Figur 1 ersichtlich. Diese Aufziehwelle 2 kann beispielsweise eine kantige Form oder eine Rundform mit Nut und Feder aufweisen. Im Gehäuse 1 ist ein Zylinderkörper 3 gelagert, welcher den Spulenkörper 4 für das Aufzugsband 5 des Lamellenstorens umfasst. Der Zylinderkörper 3 kann selbstverständlich auch mehrteilig aufgebaut sein. Die Aufziehwelle 2 ist verdrehfest mit dem Zylinderkörper 3 verbunden, beispielsweise durch eine Nuten-Federverbindung oder rein Formschlüssig mittels kantigem Querschnitt. Durch Verdrehen der Aufziehwelle 2 mittels eines Betätigungsorgans, beispielsweise einer Kurbel oder eines Motors (nicht dargestellt), wird das Aufzugsband 5 auf den Spulenkörper 4 aufgewickelt resp. abgewickelt und damit der Lamellenstoren angehoben resp. abgesenkt.An embodiment of the present invention is explained in more detail below with reference to drawings. Show it:
  • Figure 1 shows schematically the section through an inventive device with partially lowered slat blinds.
  • 2 shows schematically the section according to FIG. 1 with the slat blind completely lowered;
  • 3 schematically shows the slat positions of the two slat blind areas in the open position;
  • Fig. 4 shows the representation of Figure 3 in the lowered position (intermediate position).
  • FIG. 5 shows the representation according to FIG. 3 in the pivoted position (completely lowered);
The pull-up shaft 2 of the slat blind is inserted into the housing 1 of the gathering and pivoting device according to the invention, as can be seen from FIG. This winding shaft 2 can for example have an angular shape or a round shape with tongue and groove. In the housing 1, a cylinder body 3 is mounted, which comprises the bobbin 4 for the winding belt 5 of the slat blind. The cylinder body 3 can of course also be constructed in several parts. The winding shaft 2 is non-rotatably connected to the cylinder body 3, for example by means of a tongue and groove connection or purely positively by means of an angular cross section. By rotating the winding shaft 2 by means of an actuating member, for example a crank or a motor (not shown), the winding band 5 is wound onto the bobbin 4. handled and thus the slat blind raised or. lowered.

Auf dem Zylinderkörper 3 sind zwei Wendeelemente in Form von Wippenscheiben 6,7 verdrehbar aufgesteckt. Die Wippenscheiben 6,7 sind mittels Schraubenfedern 8,9 reibschlüssig mit dem Zylinderkörper 3 Verbunden. Solange die abgebogenen Federenden 8',8'' resp. 9',9'' der Schraubenfedern 8,9 nicht an einen Anschlag gebracht werden, werden die beiden Wippenscheiben 6,7 zusammen mit dem Zylinderkörper bewegt. Sobald die Federenden 8',8'' resp. 9',9'' an einen entsprechenden Anschlag gelangen, wird der Reibschluss gelockert und die Wippenscheiben 6 resp. 7 verbleiben in der entsprechenden Stellung. An den Wippenscheiben 6,7 sind die Enden 10,11 resp. 12,13 der Schwenkorgane eines oberen und unteren Lamellenbehangbereiches angebracht. Durch die Drehbewegung der Wippenscheiben 6,7 werden diese. Schwenkorgane auf der einen Lamellenbehangseite hochgezogen und auf der anderen Lamellenbehangseite abgesenkt, was zu einer Schwenkbewegung aller mit den Schwenkorganen verbundenen Lamellen des Lamellenbehanges fuhrt. Die Grösse der Schwenkbewegung, d.h. der Schwenkbereich, wird durch die Anordnung der erwähnten Anschläge bestimmt.On the cylinder body 3, two turning elements in the form of rocker disks 6, 7 are rotatably attached. The rocker disks 6,7 are frictionally connected to the cylinder body 3 by means of coil springs 8,9. As long as the bent spring ends 8 ', 8''respectively. 9 ', 9''of the coil springs 8.9 cannot be brought to a stop, the two rocker disks 6,7 are moved together with the cylinder body. As soon as the spring ends 8 ', 8''respectively. 9 ', 9''come to a corresponding stop, the frictional engagement is loosened and the rocker disks 6 respectively. 7 remain in the corresponding position. On the rocker disks 6.7, the ends 10.11, respectively. 12, 13 of the swivel members of an upper and lower slat blind area. Due to the rotary movement of the rocker disks 6,7, these become. Swivel members pulled up on one slat curtain side and lowered on the other slat curtain side, which leads to a pivoting movement of all the slats of the slat curtain connected to the swivel members. The size of the swivel movement, ie the swivel range, is determined by the arrangement of the abovementioned stops.

Beim Absenken oder beim Aufziehen des Lamellenbehanges durch das erwähnte Betätigungsorgan werden die Wippenscheiben 6 und 7 immer auch in die entsprechende Richtung bis zum jeweiligen Anschlag mitbewegt. Die Endanschläge für die Wippenscheiben 6,7 werden in der Regel derart positioniert, dass der Lamellenbehang sowohl in vollständig geschlossene wie in vollständig geöffnete Stellung gebracht werden kann. Damit beim Absenken des Storenbehanges die Lamellen in eine vorbestimmte Stellung gebracht werden können, ist es bei derartigen Vorrichtungen bekannt, einen zusätzlichen Zwischenanschlag vorzusehen, welcher aus der Anschlagposition in eine Ruheposition gebracht werden kann.When lowering or when opening the lamella curtain by the aforementioned actuator, the rocker disks 6 and 7 are always moved in the corresponding direction up to the respective stop. The end stops for the rocker disks 6, 7 are generally positioned in such a way that the slatted curtain can be brought into both the fully closed and the fully open position. So that the slats can be brought into a predetermined position when the blind curtain is lowered, it is known in such devices to provide an additional intermediate stop which can be brought from the stop position into a rest position.

In Figur 1 ist der erfindungsgemäss vorgeschlagene Zwischenanschlag, als Schieber 14 mit Druckfeder 15 ausgebildet, in Anschlagposition dargestellt. Dabei kommen die Schraubenfederenden 8' und 9' gegen den Schieber 14 zum Anschlag. Um den Schieber 14 in seine in Figur 2 dargestellte Ruheposition zu verschieben, ist im Spulenkörper 4 ein radial verschiebbarer Nockenkörper 16 vorgesehen. Dieser Nockenkörper 16 wird beim aufziehen des Lamellenbehanges durch das Aufzugsband 5 gegen eine Feder 17 gegen die Aufziehwelle 2 gedrückt. Wenn das Aufzugsband 5 beim Absenken des Lamellenbehanges vollständig vom Spulenkörper 4 abgewickelt wird, verschiebt sich der Nockenkörper 16 durch die Kraft der Feder 17 radial gegen aussen und drückt den Schieber 14 gegen die Feder 15 parallel zur Aufziehwelle 2, derart, dass die Öffnungen 14' in den Drehbereich der Federenden 8' und 9' positioniert werden, wie in Fig. 2 gezeigt. Damit können die beiden Wippenscheiben 6 und 7 weiter bis zum entsprechenden Endanschlag verdreht werden. Damit ist es möglich, bei vollständig abgesenktem Lamellenbehang die Stellung der Lamellen beider Behangbereiche vorzugsweise in eine vollständig geschlossene resp. offene Lage zu bringen. Dies erfolgt durch Verdrehen der Aufziehwelle 2 mittels des erwähnten Betätigungsorgans.In Figure 1, the intermediate stop proposed according to the invention, designed as a slide 14 with compression spring 15, is shown in the stop position. The coil spring ends 8 'and 9' come to a stop against the slide 14. In order to move the slide 14 into its rest position shown in FIG. 2, a radially displaceable cam body 16 is provided in the coil body 4. This cam body 16 is pressed by the elevator belt 5 against a spring 17 against the winding shaft 2 when the lamella curtain is pulled up. When the winding belt 5 is completely unwound from the coil body 4 when the lamella curtain is lowered, the cam body 16 is displaced radially outwards by the force of the spring 17 and presses the slide 14 against the spring 15 parallel to Wind-up shaft 2, such that the openings 14 'are positioned in the range of rotation of the spring ends 8' and 9 ', as shown in FIG. 2. The two rocker disks 6 and 7 can thus be rotated further until the corresponding end stop. This makes it possible, with the slats completely lowered, the position of the slats of both curtain areas preferably in a completely closed or. bring open situation. This is done by rotating the winding shaft 2 by means of the actuator mentioned.

Die Wirkung der Anschläge wird anhand der schematischen Figuren 3 bis 5 erläutert. Dabei zeigt jeweils die Fig. a) den oberen Lamellenbereich und Fig. b) den unteren Lamellenbereich der übersichtlichkeit halber nebeneinander.The effect of the stops is explained with the aid of the schematic FIGS. 3 to 5. In each case, FIG. A) shows the upper slat area and FIG. B) the lower slat area next to each other for the sake of clarity.

Durch Drehen der Aufziehwelle in Pfeilrichtung werden über die Reibkupplungen die beiden Wippenscheiben 6 und 7 ebenfalls mitgenommen, bis ihre zugehörigen Federenden 8' resp. 9' an die jeweiligen Endanschläge 18 resp. 20 anliegen. Damit werden die Lamellen 22 resp. 23 des Lamellenbehanges in die dargestellte, horizontale Lage, d.h. vollständig geöffnete Lage, gebracht. In dieser Lage können die Lamellen durch das Aufzugsband sauber aufgezogen werden.By turning the wind-up shaft in the direction of the arrow, the two rocker disks 6 and 7 are also taken along via the friction clutches until their associated spring ends 8 'and. 9 'to the respective end stops 18 resp. 20 concerns. So that the slats 22 respectively. 23 of the slat curtain in the horizontal position shown, i.e. fully open position, brought. In this position, the slats can be neatly pulled up by the elevator belt.

Wenn nun der Lamellenbehang abgesenkt werden soll, wird die Aufziehwelle wie in Fig. 4 dargestellt in Pfeilrichtung verdreht. Dabei ist der Schieber 14, wie vorhergehend anhand der Figuren 1 und 2 erläutert, in Anschlagstellung. Das Federende 8'' der Wippenscheibe 6 kommt damit gleich an den als Anschlag dienenden Schieber 14 zum Anliegen, wie in Fig. 4 a) dargestellt. Damit verbleiben die Lamellen 22 beim Absenken annähernd in der gezeigten, geöffneten Stellung. Die Wippenscheibe 7 wird beim Absenken um einen bestimmten Winkel, hier beispielsweise ca. 37o verschwenkt, bis das Federende 9'' ebenfalls an den Schieber 14 zum Anschlag kommt. Dadurch werden die Lamellen 23 über die Schwenkorgane 12, 13 in eine leicht geschlossenen Lage verschwenkt (in den Figuren ist auf der rechten Seite des Lamellenbehanges die Innenseite und auf der linken Seite die Aussenseite eines Gebäudes zu verstehen). Damit wird der Lamellenbehang mit im oberen Bereich geöffneten und im unteren Bereich teilweise geschlossenen Lamellen abgesenkt. Diese Einstellung ist insbesondere für Bildschirmarbeitsplätze vorteilhaft. Solbald der Behang vollständig abgesenkt ist, wird der Schieber 14, wie vorgängig beschrieben derart verschoben, dass die Anschlagwirkung aufgehoben wird. Damit können nun die Wippenscheiben, wie in Figur 5 dargestellt, in Pfeilrichtung weiter verschwenkt werden, bis die Federenden 8'' resp. 9'' an die entsprechenden Endanschläge 19 resp. 21 gelangen und damit in beiden Lamellenbehangbereichen die Lamellen 22 resp. 23 vollständig geschlossen werden können. In dieser vollständig abgesenkten Stellung können die beiden Wippen 6 und 7 beliebig frei zwischen den Endanschläge 18 und 19 resp. 20 und 21 durch Verdrehen der Aufziehwelle verschwenkt werden. Sobald die Aufziehwelle weiter in Aufziehrichtung (Pfeilrichtung in Figur 3) verdreht wird, wird der Lamellenbehang durch das Aufzugsband wieder aufgezogen und der Schieber 14 damit wieder in Anschlagstellung gebracht (Stellung nach Figur 3).If the slat curtain is now to be lowered, the winding shaft is rotated in the direction of the arrow as shown in FIG. 4. As previously explained with reference to FIGS. 1 and 2, the slide 14 is in the stop position. The spring end 8 ″ of the rocker disk 6 thus immediately comes to rest against the slide 14 serving as a stop, as shown in FIG. 4 a). Thus, the slats 22 remain approximately in the open position shown when lowering. The rocker 7 is pivoted when lowering by a certain angle, here for example about 37 o , until the spring end 9 ″ also comes to a stop against the slide 14. As a result, the slats 23 are pivoted via the swivel members 12, 13 into a slightly closed position (in the figures is on the inside of the slat curtain on the right-hand side and the outside of a building on the left-hand side). This lowers the slat curtain with the slats open in the upper area and partially closed in the lower area. This setting is particularly advantageous for VDU workstations. As soon as the curtain is completely lowered, the slide 14 is moved, as described above, in such a way that the stop action is canceled. The rocker disks can now be pivoted further in the direction of the arrow, as shown in FIG. 5, until the spring ends 8 ″ or. 9 '' to the corresponding end stops 19 resp. 21 arrive and thus the slats 22 and in both slat curtain areas. 23 can be closed completely. In this completely lowered position, the two rockers 6 and 7 can freely between the end stops 18 and 19 respectively. 20 and 21 can be pivoted by turning the winding shaft. As soon as the wind-up shaft is rotated further in the wind-up direction (arrow direction in FIG. 3), the slat curtain is pulled up again by the elevator belt and the slider 14 is thus brought back into the stop position (position according to FIG. 3).

Die Lage des Aufzugsbandes und der Schwenkorgane an den Lamellen ist in Figur 6 schematisch dargestellt. Der Lamellenbehang wird durch die Lamellen 22 im oberen und die Lamellen 23 im unteren Bereich gebildet. Das Aufzugsband 5, welches auf den Spulenkörper 4 aufgewickelt werden kann, führt durch Öffnungen 22', 23' in den Lamellen 22, 23 hindurch zu einer (nicht dargestellten) Abschlusslamelle. Die Lamellen 22 des oberen Lamellenbehangbereiches sind durch Schwenkschnüre 10, 11 miteinander verbunden. Die Schwenkschnüre 10, 11 führen zur Wippenscheibe 6.

Vorteilhafterweise weisen die Schwenkschnüre 10,11 resp. 12,13 zwischen der jeweiligen obersten Lamelle des entsprechenden Lamellenbehangbereiches und der entsprechenden Wippenscheibe 6 resp. 7 Längenverstellorgane auf. Damit kann die Grundlamellenstellung beim fertig eingebauten Lamellenbehang noch genau eingestellt werden.The position of the elevator belt and the swivel members on the slats is shown schematically in FIG. The slat curtain is formed by the slats 22 in the upper area and the slats 23 in the lower area. The elevator belt 5, which can be wound onto the spool 4, leads through openings 22 ', 23' in the slats 22, 23 to a closing slat (not shown). The slats 22 of the upper slat curtain area are connected to one another by swivel cords 10, 11. The swivel cords 10, 11 lead to the rocker disk 6. By rotating the swivel disk 6, the slats 22 can be pivoted together. The slats 23 of the lower slat curtain area are also connected to one another by further swivel cords 12, 13 and can be swiveled by the rocker disk 7. These swivel cords 12, 13 are for example by eyelets 24 on the Slats 22 out. Advantageously, the swivel cords 10, 11 respectively. 12, 13 between the respective uppermost slat of the corresponding slat curtain area and the corresponding rocker disk 6, respectively. 7 length adjustment elements. This means that the basic slat position can be precisely adjusted when the slatted curtain is fully installed.

Die vorgeschlagenen erfindungsgemässe Vorrichtung eignet sich insbesondere für einen Lamellenbehang mit in einem oberen und unteren Bereich getrennt verschwenkbaren Lamellen, wie sie insbesondere Vorteilhaft für Bildschirmarbeitsplätze eingesetzt werden. Damit ist es auf einfachste Weise möglich, die Lamellenstellungen beider Behangbereiche bedürfnisgerecht mit nur einem einzigen Bedienorgang zu verstellen und den ganzen Lamellenbehang abzusenken oder aufzuziehen.The proposed device according to the invention is particularly suitable for a slatted curtain with slats which can be pivoted separately in an upper and lower region, as are particularly advantageously used for VDU workstations. This makes it very easy to adjust the slat positions of both curtain areas as required with just a single operation and to lower or open the entire slat curtain.
