Description

Die vorliegende Erfindung betrifft eine Endschaltervorrichtung einer Antriebsvorrichtung für Jalousien oder dergleichen, die zum Antrieb einer drehbar gelagerten Welle geeignet ist, mit deren Hilfe die Jalousie bis zu einer Endstellung bewegt werden kann, mit Mitteln zur Erfassung der Endstellung, die mit einer Schalteinrichtung zum Abschalten des Antriebs der Welle in Verbindung steht, so daß der Antrieb bei Erreichen der Endstellung abgeschaltet wird. The present invention relates to a limit switch device a drive device for blinds or the like, suitable for driving a rotatably mounted shaft is, with the help of the blind up to a final position can be moved, with means for detecting the end position, with a switching device for switching off the Drive the shaft is connected, so that the drive is switched off when reaching the end position.

Eine derartige Schaltervorrichtung für eine obere Endstellung ist beispielsweise durch Herstellung und Vertrieb der Firma J. Stehle + Söhne GmbH bekanntgeworden.Such a switch device for an upper end position is, for example, through manufacturing and distribution of Company J. Stehle + Söhne GmbH became known.

Ebenso zeigt das Dokument FR 2 554 158 solch einer Schaltervorrichtung.Likewise, document FR 2 554 158 shows such a switch device.

Jalousien besitzen Materialblätter aus Metall, Kunststoff oder Holz, die durch Zugseile, Zuggurte oder Kordeln senkrecht übereinander gehalten werden. Die Materialblätter können in verschiedener Lage festgestellt werden und in unterschiedlichen Positionen zueinander ausgerichtet sein. Um die Materialblätter der Jalousie bewegen zu können, besitzt eine Antriebsvorrichtung einen elektrischen Antriebsmotor. Mit Hilfe des Antriebsmotors kann eine drehbar gelagerte Welle angetrieben werden, die mit der Jalousie in Verbindung steht.Venetian blinds have metal material sheets, plastic or wood, by traction ropes, pull straps or cords vertically are held one above the other. The material sheets can be ascertained in different situation and in different Positions aligned with each other. To the Moving material sheets of the blind, has a Drive device an electric drive motor. With Help the drive motor, a rotatably mounted shaft be powered, which communicates with the blind stands.

Zusätzlich ist innerhalb der Antriebsvorrichtung eine Endschaltervorrichtung vorgesehen, die ein gezieltes Abschalten des Antriebsmotors in einer oberen Endstellung der Jalousie ermöglicht. Durch den Betrieb und das Abschalten des Antriebsmotors können die Materialblätter in die gewünschte Lage gebracht werden. Die Endschaltervorrichtung dient dazu, die Materialblätter der Jalousie in eine fest vorgegebene obere Position zu bringen. Beispielsweise kann es beabsichtigt sein, die Jalousie stets bezüglich eines Blendrahmens eines Fensters so zu positionieren, daß ein Teil der Fensteröffnung bündig mit einem unteren Rand des Blendrahmens abgedeckt ist.Additionally, within the drive device is a limit switch device provided that a targeted shutdown of the drive motor in an upper end position of the blind allows. By operating and switching off the drive motor can the material sheets in the desired Able to be brought. The limit switch device serves the material sheets of the blind in a fixed predetermined to bring the upper position. For example, it may be intended be, the blind always with respect to a frame a window so that a part of the window opening flush with a lower edge of the frame is covered.

Zur Abschaltung des Antriebsmotors wird eine Schalteinrichtung verwendet, die bei Erreichen einer bestimmten Endstellung aktiviert wird. To shut off the drive motor is a switching device used when reaching a certain end position is activated.

Aufgabe der vorliegenden Erfindung ist es, einerseits die Handhabung der Justierung der Endstellung zu vereinfachen und andererseits die Justierung präziser durchführen zu können.Object of the present invention is, on the one hand the Handling the adjustment of the end position to simplify and on the other hand to be able to perform the adjustment more precisely.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß eine separate Betätigungseinrichtung zur Deaktivierung der Mittel zur Erfassung der Endstellung vorgesehen ist, und daß die Betätigungseinrichtung derart ausgebildet ist, daß eine erneute Aktivierung der deaktivierten Mittel und gleichzeitige Definition einer neuen Endstellung durch Umkehrung der Bewegungsrichtung der Welle erreichbar ist.This object is achieved in that a separate actuator for deactivating the means is intended to detect the end position, and that the Actuating device is designed such that a renewed Activation of deactivated funds and simultaneous Definition of a new end position by reversing the direction of movement the shaft is reachable.

Die separate Betätigungseinrichtung hat den Vorteil, daß eine obere Endstellung der Jalousie einstellbar ist, indem die Mittel zur Erfassung der Endstellung zunächst außer Kraft gesetzt werden und anschließend die Endstellung durch ein Verfahren der Materialblätter der Jalousie neu definiert wird. Wenn beispielsweise die gewünschte obere Stellung der Materialblätter erreicht ist, wird einfach in die andere Bewegungsrichtung der Materialblätter, nämlich ein Verfahren nach unten, durch den Anwender umgeschaltet. Der Umkehrpunkt der Antriebsrichtung der Welle definiert die neue Endstellung. Wann immer bei einer erneuten Nach-Oben-Bewegung der Materialblätter diese Endstellung erreicht wird, wird der Antriebsmotor abgeschaltet.The separate actuator has the advantage that a upper end position of the blind is adjustable by the Means for detecting the end position initially overridden be set and then the end position by a Redefining of the material sheets of the blind becomes. For example, if the desired upper position of Material sheets is reached, simply in the other direction of movement the material sheets, namely a method down, switched by the user. The reversal point the drive direction of the shaft defines the new end position. Whenever a renewed up-move the Material leaves this end position is achieved, the Drive motor switched off.

Folglich läßt sich die Justierung einer neuen Endstellung einfach durchführen, ohne daß an der Endschaltervorrichtung selbst Eingriffe vorgenommen werden müssen. Consequently, the adjustment of a new end position can be simply perform without on the limit switch device even interventions need to be made.

Bei einer bevorzugten Ausführungsform umfaßt die Betätigungseinrichtung einen quer zur Drehachse der Welle verschieblich angeordneten Betätigungshebel, der aus einer Ruhestellung in eine Justierstellung zum Einstellen der Endstellung bewegbar ist und in der Justierstellung an der Welle justierbar arretiert ist, wobei die Mittel zur Erfassung der Endstellung durch mehrere, mit der Schalteinrichtung in Verbindung stehende Zählscheiben gebildet ist, die durch bei einer Drehbewegung der Welle rotierende Schaltscheiben antreibbar sind, und in der Justierstellung die Verbindung zwischen Schaltscheiben und Zählscheiben unterbrochen ist, so daß die Zählscheiben in eine Position bringbar sind, die der Endstellung entsprechen.In a preferred embodiment, the actuator comprises one displaceable transversely to the axis of rotation of the shaft arranged actuating lever, which from a rest position in an adjustment position for setting the end position is movable and in the adjustment position on the shaft is locked adjustable, the means for detection the end position by several, with the switching device in Compound counting discs is formed by at a rotating movement of the shaft rotating discs driven are, and in the adjustment position the connection between switching discs and counting discs is interrupted, so that the counting discs can be brought into a position, the correspond to the end position.

Die Welle der Antriebsvorrichtung ist in der Regel waagerecht über der Fensteröffnung angebracht. Der Betätigungshebel kann deshalb quer zur Drehachse der Welle in vertikaler Richtung nach unten gezogen werden, so daß er einfach zu bedienen ist. Das Nachuntenziehen des Betätigungshebels bewirkt, daß die Mittel zur Erfassung der Endstellung außer Kraft gesetzt werden. Als Mittel zur Erfassung können in bekannter Weise durch Schaltscheiben angetriebene Zählscheiben verwendet werden, wie sie beispielsweise in einer Vielzahl von Zählwerken (Registrierkassen, Kilometerzähler) verwendet werden. Durch die Umkehrung der Antriebsrichtung der Welle wird die lösbare Verbindung zwischen Betätigungshebel und Welle wieder aufgehoben, so daß die Schaltscheiben wieder an den Zählscheiben anliegen.The shaft of the drive device is generally horizontal mounted above the window opening. The operating lever can therefore transverse to the axis of rotation of the shaft in vertical Direction to be pulled down so that it is easy to use is. The pulling down of the operating lever causes that the means for detecting the end position except Force to be set. As a means of detection can in known Way powered by indexing discs driven dials used, as for example in a variety used by counters (cash registers, odometer) become. By reversing the drive direction of the shaft is the releasable connection between the operating lever and Wave lifted again, so that the discs again abut the counting discs.

Eine exakte Positionierung der Zählscheiben ist bei einer Weiterentwicklung dieser Ausführungsform dadurch möglich, daß ein Einstellschlitten der Betätigungseinrichtung vorgesehen ist, der in der Justierstellung des Betätigungshebels durch diesen auslenkbar ist und mit Schlittenabsätzen in Einkerbungen einrastet, die an herzförmigen Scheibenabsätzen der Zählscheiben ausgebildet sind. Durch die Entlangbewegung des Einstellschlittens an den herzförmigen Scheibenabsätzen wird gewährleistet, daß die Zählscheiben zur Neueinstellung der Endstellung stets in die gleiche Ruhelage bewegt werden können. Der Einstellschlitten dient einem definierten Reset (Rücksetzen) der Zählscheiben.An exact positioning of the dials is at a Further development of this embodiment thereby possible that a Einstellschlitten the actuator provided is that in the adjustment position of the actuating lever is deflectable by this and with sledges in Notches snaps on heart-shaped disc heels the counting discs are formed. By the movement along of the adjustment slide on the heart-shaped disc heels it is ensured that the dials for readjustment the end position are always moved to the same rest position can. The adjustment slide serves a defined reset (Reset) of the dials.

Die lösbare Verbindung zwischen Betätigungshebel und Welle kann auf einfache Art und Weise dadurch erreicht werden, daß der Betätigungshebel einen Hebelarm aufweist, der an seiner Unterseite mit einer Verzahnung ausgebildet ist, und daß die Welle an einem Teil ihrer Außenumfangsfläche eine auf diese Verzahnung abgestimmte Verzahnung besitzt, in die die Verzahnung des Hebelarms in der Justierstellung eingreifen kann. Der Hebelarm ist flexibel ausgebildet, so daß er federnd mit seiner Verzahnung an der Welle aufliegen kann. Eine Drehbewegung der Welle in Richtung der schräg geneigten Zähne der Verzahnung führt dazu, daß die Welle bei aufliegendem Hebelarm unter diesem hindurchrutscht, den Hebelarm aber nicht abwirft. Erst eine Umkehrung der Drehrichtung löst die Verbindung zwischen Hebelarm und Welle, da die Verzahnung den Hebelarm freigibt.The detachable connection between the operating lever and the shaft can be achieved in a simple manner that the operating lever has a lever arm, which at its Bottom is formed with a toothing, and that the Wave on one part of its outer peripheral surface one on top of it Gearing has coordinated toothing, in which the gearing engage the lever arm in the adjustment position can. The lever arm is flexible, so that it is springy can rest with its teeth on the shaft. A Rotary movement of the shaft in the direction of the obliquely inclined Teeth of the teeth causes the shaft when lying on Lever arm slips under this, the lever arm but do not throw off. Only a reversal of the direction of rotation releases the connection between the lever arm and the shaft, because the teeth releases the lever arm.

Bevorzugt ist es, daß der Betätigungshebel gegen die Federkraft einer Blattfeder in die Justierstellung bewegbar ist. Die Blattfeder führt zu einer lösbaren Arretierung des Betätigungshebels an der Welle unter einer Vorspannung. Wenn die Welle den Hebelarm wieder freigibt, so kann durch die Blattfeder der Betätigungshebel wieder in seine Ausgangsstellung gedrückt werden. Die Mittel zur Erfassung der Endstellung werden bei diesem Vorgang wieder in reproduzierbarer Weise aktiviert.It is preferred that the actuating lever against the spring force a leaf spring is movable in the adjustment position. The leaf spring leads to a releasable locking of the actuating lever on the shaft under a bias. If the Shaft releases the lever arm again, so can through the leaf spring the operating lever back to its original position be pressed. The means for detecting the end position become reproducible in this process again activated.

Die Erfindung ist in den Figuren schematisch dargestellt, so daß die wesentlichen Merkmale der Erfindung gut zu erkennen sind. Die Darstellungen sind nicht notwendigerweise maßstäblich zu verstehen.The invention is shown schematically in the figures, see above that the essential features of the invention are clearly visible are. The illustrations are not necessarily to scale to understand.

In der Fig. 1 ist eine Endschaltervorrichtung 10 zur erkennen, die eine Schaltplatine 11 aufweist. Die Schaltplatine 11 besitzt einen zentralen Steckkontakt 12 zum Anschluß an eine Stromversorgung. An der Schaltplatine 11 sind Anschlußplätze 13 und 14 ausgebildet, an denen elektrische Endschalter zum Abschalten eines elektrischen Antriebsmotors befestigt werden können. Beim zusammengebauten Gerät sind dort Endschalter befestigt (hier nicht gezeigt). Darüberhinaus besitzt die Schaltplatine 11 Federkontakte zur elektrischen Verbindung weiterer Bauelemente mit der Schaltplatine 11, von denen einer mit der Bezugsziffer 15 bezeichnet ist. Innerhalb einer Abdeckhaube 16 sind Mittel zur Erfassung der Endstellung einer Jalousie untergebracht, die mit den elektrischen Endschaltern auf der Platine 11 zusammenwirken können, um den Antriebsmotor abzuschalten. Eine in der Figur nicht gezeigte Welle der Antriebsvorrichtung kann um eine Drehachse 17 in Rotation gesetzt werden. Die Welle ist durch die Abdeckhaube 16 über eine angedeutete Haubenöffnung 18 hindurchgeführt.In Fig. 1 , a limit switch device 10 is to recognize that has a circuit board 11. The circuit board 11 has a central plug contact 12 for connection to a power supply. On the circuit board 11 terminal points 13 and 14 are formed, where electrical limit switches can be attached to turn off an electric drive motor. When assembled device limit switches are fixed there (not shown here). In addition, the circuit board 11 has spring contacts for electrically connecting further components to the circuit board 11, one of which is designated by the reference numeral 15. Within a cover 16 means for detecting the end position of a blind are housed, which can cooperate with the electrical limit switches on the board 11 to turn off the drive motor. A not shown in the figure shaft of the drive device can be set about a rotation axis 17 in rotation. The shaft is passed through the cover 16 via an indicated hood opening 18.

Die Mittel zur Erfassung der Endstellung der Jalousie umfassen Schaltscheiben 19 und Zählscheiben 20. Die Zählscheiben 20 bilden ein Zählwerk, bei dem die Zählscheiben 20 miteinander über Nocken 21 in Verbindung stehen. Nach eine vollständigen Umdrehung einer ersten Zählscheibe 20 wird eine zweite Zählscheibe 20 ebenfalls leicht verdreht, so daß mehrere Zählscheiben 20 die Anzahl von Drehungen der Welle erfassen können. Die Zählscheiben 20 werden über die Schaltscheiben 19 entsprechend angetrieben. Die Schaltscheiben 19 wiederum sind mit der Welle verbunden.The means for detecting the end position of the blind include Indexing discs 19 and counting discs 20. The counting discs 20 form a counter, in which the counting discs 20 with each other via cam 21 in connection. After a complete Rotation of a first counting disc 20 becomes a second counting disc 20 also slightly twisted, so that several Counts 20 detect the number of rotations of the shaft can. The counting discs 20 are on the switching discs 19 driven accordingly. The switching discs 19 in turn are connected to the shaft.

Wenn die Jalousie an einem Schaltfühler 21 zur Anlage kommt (direktes Abfühlen), wird im Innern der Abdeckhaube 16 ein Schaltbügel ausgelenkt, um den elektrischen Endschalter zu betätigen. Der längsverstellbare Schaltfühler 21 ist in einer Schaltfühlerhülse 22 verschieblich angeordnet. Der Schaltfühler 21 wird auch in Alleinstellung als erfinderisch betrachtet. When the blind comes to a switching sensor 21 to the plant (Direct sensing), is inside the cover 16 a Switch handle deflected to the electric limit switch too actuate. The longitudinally adjustable switching sensor 21 is in one Switching sensor sleeve 22 slidably disposed. Of the Switching sensor 21 is also in isolation as inventive considered.

Durch eine Auslenkung des Schaltfühlers 21 in Betätigungsrichtung 23 läßt sich auch ein Betätigungshebel 24 zur Justierung einer Endstellung der Zählscheiben 20 bedienen. Durch die Verschiebung des Betätigungshebels 24 in Pfeilrichtung 23 wird die Verbindung zwischen Schaltscheiben 19 und Zählscheiben 20 unterbrochen. Die Welle kann dann durch den Antriebsmotor betätigt werden, ohne daß eine Erfassung dieser Drehbewegung durch die Zählscheiben 20 erfolgt. Wenn die Zählscheiben 20 auf Null zurückgestellt werden, kann bei erneuter Anlage der Schaltscheiben 19 an den Zählscheiben 20 eine neue Endstellung für die Jalousie definiert werden. Ist die Endstellung erreicht (indirektes Abfühlen), schaltet der Antrieb ab. Während die Zählscheiben 20, d.h. die Mittel zur Erfassung der Endstellung, außer Kraft gesetzt sind, dient der Schaltfühler 21 als Sicherung, um zu verhindern, daß die Jalousie über die Endstellung hinausbewegt wird.By a deflection of the switching sensor 21 in the direction of actuation 23 can also be an operating lever 24 for adjustment operate an end position of the counting wheels 20. By the displacement of the actuating lever 24 in the arrow direction 23, the connection between the switching discs 19th and counting discs 20 interrupted. The wave can then go through the drive motor are operated without a detection this rotational movement is carried out by the counting discs 20. If the counting wheels 20 are reset to zero, can at re-installation of the switching discs 19 on the counting discs 20th a new end position for the blind can be defined. is reaches the end position (indirect sensing), the switches Drive off. While the dials 20, i. the means for Capture the end position, override, is used the switching sensor 21 as a fuse to prevent the Venetian blind is moved beyond the end position.

In der Fig. 2 ist die Endschaltervorrichtung 10 mit ihrem teilweise freigelegten Inneren gezeigt. Eine Welle 25 kann um die Drehachse 17 in Rotation versetzt werden. Fig. 2 stellt den justierten Zustand der Mittel zur Erfassung der Endstellung dar, bei der die Zählscheiben 20 mit den Schaltscheiben 19 in Eingriff stehen.In Fig. 2 , the limit switch device 10 is shown with its partially exposed interior. A shaft 25 can be rotated about the rotation axis 17. Fig. 2 illustrates the adjusted state of the means for detecting the end position, in which the counting discs 20 are in engagement with the switching discs 19.

Zur Justierung der Endstellung wird der Betätigungshebel 24 in Pfeilrichtung 23 nach unten bewegt. Durch die Bewegung des Betätigungshebels 24 wird auch ein Gehäuseteil 26 mitbewegt, so daß auch eine Halterung 27 für die Schaltscheiben 19 ausgelenkt wird. Die Schaltscheiben 19 entfernen sich von den Zählscheiben 20 und befinden sich dann in einem Zustand, wo sie von den Zählscheiben 20 außer Eingriff sind. Ein Zapfen 28 der Halterung 27 ist in einer Ausnehmung 29 des Gehäuseteils 26 verschieblich gelagert. To adjust the end position of the actuating lever 24th in the direction of arrow 23 moves down. Through the movement of the actuating lever 24, a housing part 26 is also moved, so that a holder 27 for the switching discs 19 is deflected. The switching discs 19 move away from the counting discs 20 and are then in a state where they are disengaged from the dials 20. A cone 28 of the holder 27 is in a recess 29 of the housing part 26 slidably mounted.

Durch die Verschiebung des Betätigungshebels 24 kommen Anschlagflächen 30 des Betätigungshebels 24 an oberen Enden 31 eines Einstellschlittens 32 zur Anlage. Die Anschlagfläche 30 kann den schwenkbar gelagerten Einstellschlitten 32 auslenken bzw. niederdrücken, so daß Schlittenabsätze 33 an die Zählscheiben 20 anstoßen.Due to the displacement of the actuating lever 24 stop surfaces come 30 of the operating lever 24 at upper ends 31st a Einstellschlittens 32 to the plant. The stop surface 30 can deflect the pivotally mounted Einstellschlitten 32 or depress, so that carriage heels 33 to the Abut counter discs 20.

Der Betätigungshebel 24 kann in Pfeilrichtung 23 gegen die Federwirkung einer Blattfeder 34 verfahren werden. Die Blattfeder 34 drückt gegen einen Schaltbügel 35, der einenends in eine Schaltplatte 36 übergeht, über die der elektrische Endschalter (siehe Fig. 1) aktiviert werden kann.The actuating lever 24 can in the direction of arrow 23 against the Spring action of a leaf spring 34 are moved. The Leaf spring 34 presses against a switch bracket 35, the one end goes into a circuit board 36, via which the electrical Limit switch (see Fig. 1) can be activated.

Der Betätigungshebel 24 wird in der Justierstellung für die Endstellung an der Welle 25 gehalten, wenn die Welle 25 in Pfeilrichtung 37 gedreht wird, und eine Gegenverzahnung 38 der Welle 25 in eine Verzahnung 39 eines Hebelarms 40 eingreifen kann. Beim Antrieb der Welle 25 in Pfeilrichtung 37 wird der Hebelarm 40 leicht mitgezogen. Der Hebelarm 40 ist elastisch ausgebildet, so daß er mit seiner Verzahnung 39 rutschend auf der Welle 25 aufliegt. Eine Umkehrung der Drehbewegung in Pfeilrichtung 37' führt dazu, daß der Hebelarm 40 von der Welle 25 abgestoßen wird. Durch die Wirkung der Blattfeder 34 wird der Betätigungshebel 24 wieder in seine Ausgangslage zurückgestellt. Die Schaltscheiben 19 liegen dann wieder an den Zählscheiben 20 an, so daß eine Drehbewegung der Welle 25 wieder erfaßt wird. Bei entsprechender Anzahl der Drehbewegungen kann dann der Schaltbügel 35 den elektrischen Endschalter aktivieren, um den Antriebsmotor auszuschalten. The actuating lever 24 is in the adjustment position for the End position held on the shaft 25 when the shaft 25 in Arrow direction 37 is rotated, and a counter toothing 38th the shaft 25 engage in a toothing 39 of a lever arm 40 can. When driving the shaft 25 in the direction of arrow 37th the lever arm 40 is easily pulled along. The lever arm 40 is elastically formed so that it with its teeth 39 slipping on the shaft 25 rests. A reversal of the Rotary movement in the direction of arrow 37 'causes the lever arm 40 is repelled by the shaft 25. By the effect the leaf spring 34, the operating lever 24 is back in his initial position is reset. The switching discs 19 are then back to the counting discs 20, so that a Rotary movement of the shaft 25 is detected again. With appropriate Number of rotational movements can then the switch bracket 35 activate the electrical limit switch to the drive motor off.

Fig. 3 zeigt das Zusammenwirken des Einstellschlittens 32 mit den Zählscheiben 20. Der übersichtlichen Darstellung wegen wurden gegenüber Fign. 1 und 2 weitere Bauteile der Endschaltervorrichtung 10 nicht gezeigt. Die Zählscheiben 20 besitzen Scheibenabsätze 41, die eine herzförmige Umrißkontur 42 aufweisen. Durch die herzförmige Umrißkontur 42 kommt eine Einkerbung 43 zustande, in die ein Schlittenabsatz 33 einrasten kann. Der Schlittenabsatz 33 kann sich an der Umrißkontur 42 entlangbewegen, bis die eingerastete Position erreicht ist. In dieser Stellung befindet sich die Zählscheibe 20 in ihrer definierten Ausgangsstellung.FIG. 3 shows the interaction of the adjustment slide 32 with the dials 20. The clear view because were compared to Fign. 1 and 2 further components of the limit switch device 10 not shown. The counting discs 20 own disc heels 41, which have a heart-shaped outline contour 42 have. Through the heart-shaped contour contour 42 comes a notch 43, into which a carriage paragraph 33 can engage. The carriage paragraph 33 may be on the outline contour 42 move along until the locked position is reached. In this position is the counting disc 20 in their defined starting position.

Die Endabschaltung durch die Endschaltervorrichtung 10 erfolgt in der folgenden Weise: Zunächst wird die Jalousie durch Drehbewegung der Welle 25 in Pfeilrichtung 37' herunter bewegt. Schaltscheiben 19 treiben dabei die Zählscheiben 20 an. Der Antrieb und die Untersetzung zwischen den Scheiben 19 und 20 erfolgt in bekannter Weise. Wenn die Jalousie durch Drehbewegung der Welle 25 in Pfeilrichtung 37 wieder nach oben bewegt wird, zählen die Zählscheiben 20 zurück, so daß bei Erreichen der Endstellung (Ausgangslage) die in Fig. 3 gezeigte Position eintritt. Die Zählscheiben 20 weisen dann an ihrer Unterseite fluchtende Aussparungen 44 auf, in die ein Schaltelement 45 des Schaltbügels 35 einfallen kann. In diesem Moment wird der elektrische Endschalter durch die Schaltplatte 36 (siehe Fig. 2) aktiviert. Die Jalousie kann jeweils nur bis zu einer oberen Position (Endstellung) bewegt werden, die durch die Anordnung der Zählscheiben 20 (justierte Ausgangslage) vorgegeben ist.The final shutdown by the limit switch device 10 takes place in the following way: First, the blinds by rotational movement of the shaft 25 in the direction of arrow 37 'down emotional. 19 shift discs drive the counting discs 20 on. The drive and the reduction between the discs 19 and 20 takes place in a known manner. If the blind by rotational movement of the shaft 25 in the direction of arrow 37 again is moved upward, the counting discs 20 count back, so that upon reaching the end position (initial position) in FIG. 3 position occurs. The counting discs 20 point then aligned on its underside recesses 44, in which may occur a switching element 45 of the switch bracket 35. At this moment, the electric limit switch is through the Switching plate 36 (see Fig. 2) activated. The blind can only moved to an upper position (end position) be determined by the arrangement of the counting wheels 20th (adjusted starting position) is given.
