Description

Die Erfindung betrifft eine Schaltvorrichtung für wenigstens eine Endlage einer elektromotorisch angetriebenen Jalousie mit wenigstens einem Paar vom Motor über ein Untersetzungsgetriebe und ein Differenzengetriebe unterschiedlich schnell angetriebener, am Umfang eine Schaltkerbe aufweisender kreisförmiger Steuerscheiben, die mit einem in die Schaltkerben eingreifenden Schalthebel eines elektrischen Schalters zusammenwirken.The invention relates to a switching device for at least one end position an electric motor-driven blind with at least one pair from the motor via a reduction gear and a differential gear a switching notch driven at different speeds having circular control disks, which with one in the Switch notches engaging the shift lever of an electrical switch work together.

Eine solche Schaltvorrichtung ist bekannt (DE-A-2426719). Diese bekannte Schaltvorrichtung weist bereits Steuerscheibenpaare auf, mit denen die Abschaltpunkte der Jalousie in einer oder beiden Endlagen derselben montagefreundlich justiert werden können.Such a switching device is known (DE-A-2426719). This well-known Switching device already has pairs of control disks with which the Switch-off points of the blind in one or both end positions of the same can be easily adjusted.

Da das Justieren der Abschaltpunkte an einem in der Kopfschiene eingebauten Jalousiemotor immer noch unbequem ist, geht das Bestreben dahin, die Montagefreundlichkeit der Jalousiemotoren in diesem Sinne weiter zu verbessern. Das der Erfindung zugrunde liegende technische Problem besteht deshalb darin, das Einstellen der Abschaltpunkte eines Jalousiemotors weiter zu vereinfachen. Because the adjustment of the switch-off points on one in the head rail built-in blind motor is still uncomfortable, the effort goes the ease of installation of the blind motors in this sense continue to improve. The technical basis of the invention The problem therefore is to set the switch-off points of a To further simplify the blind motor.

Dieses technische Problem ist erfindungsgemäß dadurch gelöst, daß eine von außen an die Steuerscheiben anstellbare und dabei in den Umfang der Steuerscheiben eingreifbare, selbsthaltende Blockiervorrichtung vorgesehen ist. Durch die erfindungsgemäße Lösung ist das Einstellen der Abschaltpunkte der Jalousie in den Endlagen derart stark vereinfacht, daß nur noch ein Stift, beispielsweise ein Schraubendreher, kurzzeitig in eine Öffnung des Jalousiemotors hineingedrückt und die Jalousie durch Betätigung eines bequem zugänglichen Tastschalters in die jeweilige Endlage gebracht werden muß.This technical problem is solved according to the invention in that a adjustable from the outside to the control discs and thereby in the scope of Control disks engaging, self-locking device provided is. The solution according to the invention is the setting of Switch-off points of the blind in the end positions so much simplified that just a pin, for example a screwdriver, for a short time in one Push the opening of the blind motor in and the blind through Actuation of an easily accessible push button switch in the respective End position must be brought.

Fig. 1 zeigt einen im wesentlichen rein äußerlich handelsüblichen Jalousiemotor mit einem Gehäuse 1, in dem die Schaltvorrichtung für das Einstellen der Abschaltpunkt der Jalousie in der oberen und/oder unteren Endlage im Bereich des Deckels 2 eingebaut ist. Der Deckel 2 weist die Öffnungen 3 und 4 auf, deren Funktion noch erklärt werden wird. Außerdem ist der Jalousiemotor über einen Tastschalter 5 mit dem Netz verbunden. Je nach Betätigung einer der beiden Tasten des Tastschalters 5 läuft der Jalousiemotor in der einen oder anderen Drehrichtung, wobei die vom Jalousiemotor betätigte Jalousie entweder geöffnet (AUF) oder geschlossen (AB) wird.Fig. 1 shows an essentially purely commercially available Blind motor with a housing 1 in which the switching device for Setting the switch-off point of the blind in the upper and / or lower End position in the area of the cover 2 is installed. The lid 2 has the Openings 3 and 4, the function of which will be explained. In addition, the blind motor is connected to the mains via a push button switch 5 connected. Depending on the actuation of one of the two buttons on the push button 5 the blind motor runs in one or the other direction of rotation, whereby the Venetian blind operated either open (OPEN) or is closed (AB).

Fig. 2 zweigt den prinzipiellen Aufbau der neuen Schaltvorrichtung. Es ist der elektrische Schalter 6 zu erkennen, welcher den Stromkreis des Jalousiemotors unterbricht, wenn die Jalousie eine Endlage erreicht hat. Außerdem ist eine Steuerscheibe 7 mit einer Kerbe 8 am Umfang erkennbar. Die Betätigung des Schaltarmes 9 des Schalters 6 erfolgt bei diesem Ausführungsbeispiel über einen Hebel 10, welcher um die Achse 1 1 schwenkbar gelagert ist. Der Hebel 10 ist derart mittels einer - nicht gezeigten - Feder vorgespannt, daß er - ohne Einwirkung von außen - an den Umfang der Steuerscheibe 7 angestellt ist. Der Umfang der Steuerscheibe 7 ist mit einer Ausnehmung 12 versehen, welche in einer Hinterschneidung 13 endet. Im Bereich des Deckels 2 ist an einem Halter 14 der Schieber 15 gegen die Kraft der Feder 16 in Richtung des Pfeiles 17 längsverschiebbar gelagert.Fig. 2 branches the basic structure of the new switching device. It is the electrical switch 6 to recognize the circuit of the Blind motor interrupts when the blind has reached an end position. In addition, a control disc 7 with a notch 8 on the circumference recognizable. The actuation of the switching arm 9 of the switch 6 takes place at this embodiment via a lever 10 which about the axis 1 1 is pivotally mounted. The lever 10 is such a - not shown - spring biased that it - without external influence - on the scope of the control disc 7 is employed. The scope of the Control disc 7 is provided with a recess 12 which in a Undercut 13 ends. In the area of the lid 2 is on a holder 14 the slide 15 against the force of the spring 16 in the direction of the arrow 17th longitudinally displaceable.

Der Schieber 15 besitzt auf der einen Seite einen Arm 18 und auf der anderen Seite eine Verdickung 19, in welcher in der Zeichenebene hintereinander zwei gegen Federkraft bewegliche Stifte 20 angeordnet sind. In Fig. 2 ist nur ein Stift 20 zu erkennen. Die Stifte 20 besitzen an ihrem oberen Ende eine Verdickung 21. Die Stifte 20 sind in der Verdickung 21 in Richtung des Pfeiles 17 federnd gelagert.The slider 15 has an arm 18 on one side and on the on the other hand, a thickening 19, in which in the plane of the drawing two pins 20 movable against spring force are arranged one behind the other. Only one pin 20 can be seen in FIG. 2. The pins 20 have on their upper end of a thickening 21. The pins 20 are in the thickening 21 in Resiliently supported in the direction of arrow 17.

Es sei darauf hingewiesen, daß die Schaltvorrichtung für die Einstellung der Abschaltpunkte in einer jeden Endlage folgende Teile benötigt: Einen Schalter 6, ein Steuerscheibenpaar, einen Hebel 10, einen Schieber 15 mit zwei Stiften 20.It should be noted that the switching device for setting the Switch-off points in each end position require the following parts: One Switch 6, a pair of control discs, a lever 10, a slide 15 with two pins 20.

Bei der in Fig. 2 gezeigten Anordnung befindet sich der Schieber 15 in der Ruhestellung, d.h. er ist nicht verschoben. Die Schaltnocke des Hebel 10 ist in die Kerbe 8 eingedrungen, d.h. daß die beiden in der Bildebene hintereinander angeordneten Steuerscheiben 7 des Steuerscheibenpaares die gleiche Drehstellung einnehmen. Dadurch war es dem Schaltarm 9 des Schalters 6 möglich, nach links zu schwenken, so daß der Schalter 6 geöffnet ist und den Stromkreis des Jalousiemotors geöffnet hat.In the arrangement shown in Fig. 2, the slide 15 is in the Resting position, i.e. he is not postponed. The switching cam of the lever 10 is penetrated into the notch 8, i.e. that the two in the picture plane control discs 7 of the control disc pair arranged one behind the other assume the same rotational position. This made it the switching arm 9 of the Switch 6 possible to pivot to the left so that the switch 6 is open and has opened the blind motor circuit.

Die aus Fig. 2 ersichtliche Stellung des Steuerscheibenpaares, des Hebels 10 und des Schaltarmes 9 des Schalters 6 entspricht einer Stellung der Schaltvorrichtung für eine Endlage der Jalousie.The apparent from Fig. 2 position of the control disc pair, the lever 10 and the switching arm 9 of the switch 6 corresponds to a position of Switching device for an end position of the blind.

Nun ist es aber denkbar, daß die Schaltvorrichtung eine Stellung besitzt, welche einer Endlage einer Jalousie entspricht, beispielsweise weil der Jalousiemotor mit einer derart voreingestellten Schaltvorrichtung ausgeliefert worden ist, die Jalousie selbst sich aber nicht in der entsprechenden Endlage befindet. Wie dann verfahren wird, ist nachstehend anhand der Figuren 3 und 4 erläutert.Now it is conceivable that the switching device has a position which corresponds to an end position of a blind, for example because of the Blind motor with such a preset switching device has been delivered, but the blind itself is not in the corresponding end position. How to proceed is explained below with reference to Figures 3 and 4.

In Fig. 3 ist die Schaltvorrichtung gezeigt, nachdem der Schieber 15 durch einen in die Öffnung 4 eingeführten Stift in Richtung des Pfeiles 22 verschoben worden ist. Dabei hat der Arm 18 den Schaltarm 9 des Schalters 6 nach rechts gedrückt, wodurch der Schalter 6 geschlossen worden ist. Außerdem sind die Verdickungen 21 der Stifte 20 an den Umfang des Steuerscheibenpaares 7 angestellt worden. Wenn jetzt durch Betätigung der entsprechenden Taste (AUF oder AB) des Tastschalters 5 der Motor eingeschaltet wird, dann ergibt sich nach einer halben Umdrehung des Steuerscheibenpaares die Lage von Verdickungen 21 und Ausnehmungen 12.In Fig. 3, the switching device is shown after the slide 15 through a pin inserted into the opening 4 in the direction of the arrow 22 has been postponed. The arm 18 has the switching arm 9 of the Switch 6 pressed to the right, whereby the switch 6 is closed has been. In addition, the thickenings 21 of the pins 20 on the Scope of the control disc pair 7 has been employed. If through now Press the corresponding button (UP or DOWN) of the push button 5 of the Engine is turned on, then results after half a turn of the control disc pair, the location of thickenings 21 and Recesses 12.

Nach einer ganzen Umdrehung des Steuerscheibenpaares 7 sind - wie aus Fig. 4 ersichtlich - die Verdickungen 21 in die Ausnehmungen 12 eingedrückt worden und die Verdickungen 21 haben in den Hinterschneidungen 13 eingerastet. Der Schieber 15 hält sich selbst in dieser Stellung. Der Motor kann jetzt durch Betätigung der entsprechenden Taste des Tastschalters 5 solange eingeschaltet bleiben, bis die Jalousie die gewünschte Endstellung erreicht hat. Dann wird kurzzeitig die andere Taste des Tastschalters 5 betätigt, wodurch das Steuerscheibenpaar in entgegengesetzte Richtung dreht. Dadurch kommen die Verdickungen 21 aus den Hinterschneidungen 13 frei, und der Schieber 15 wird von der Feder 16 in die Ruhelage befördert. Der Hebel 10 rastet wieder in die Kerbe 8 ein.After a full turn of the control disc pair 7 are - as from 4 can be seen - the thickenings 21 in the recesses 12 have been pressed in and the thickenings 21 in the Undercuts 13 locked. The slide 15 keeps itself in this position. The motor can now be operated by pressing the appropriate button Keep the button on the pushbutton switch 5 switched on until the blinds has reached the desired end position. Then the other key is briefly of the push button 5 actuated, whereby the control disc pair in opposite direction turns. This causes the thickenings 21 free from the undercuts 13, and the slide 15 is from the Spring 16 transported to the rest position. The lever 10 snaps back into the notch 8 a.

Die Einstellung des Abschaltpunktes der Jalousie in einer Endlage ist damit beendet. Die Einstellung des Abschaltpunktes der anderen Endlage erfolgt in entsprechender Weise mit einem zweiten Schieber, einem zweiten Steuerscheibenpaar und einem zweiten Schalter.The setting of the shutdown point of the blind in one end position is now completed. The switch-off point of the other end position is set in a corresponding manner with a second slide, a second Control disc pair and a second switch.

Die Figuren 5 und 6 verdeutlichen die Form einer Steuerscheibe bzw. eines Steuerscheibenpaares. Wie Fig. 6 zeigt, weist die Steuerscheibe am Umfang über die Breite ein unterschiedliches Profil auf. Auf etwa einem Drittel der Breite ist die Steuerscheibe - mit Ausnahme der Kerbe 8 - kreisförmig, wie die Stege 23 und 24 verdeutlichen. Auf der restlichen Breite der Steuerscheibe sind die Ausnehmung 12 und seitlich der Kerbe 8 eine Abflachung 25 vorgesehen.Figures 5 and 6 illustrate the shape of a control disc and one Control disc pair. As shown in Fig. 6, the control disc has on the circumference a different profile across the width. About a third of the Width is the control disc - with the exception of the notch 8 - circular, like the webs 23 and 24 illustrate. On the remaining width of the Control disc are the recess 12 and the side of the notch 8 one Flattening 25 is provided.

Auf den kreisförmigen Stegen 24 und 25 wird - wie aus Fig. 3 ersichtlich - die Spitze des Hebels 10 geführt und auf dem Boden der Ausnehmung 12 und der Abflachung 25 gleiten die Verdickungen 21 der Stife 20. On the circular webs 24 and 25 - as can be seen from FIG. 3 - guided the tip of the lever 10 and on the bottom of the recess 12 and the flat 25, the thickenings 21 of the pin 20 slide.

Die Steuerscheiben 7 sind - wie in Fig. 5 zu erkennen ist - ringförmig ausgebildet. Sie sind - wie an sich bekannt - auf den Hohlachsen der Zahnräder des Differenzengetriebes zwar festgespannt, aber nach Überwindung einer bestimmten Kraft in der Art einer Rutschkupplung in Umfangsrichtung verdrehbar. Das Festspannen der Steuerscheiben wird durch eine - in Fig. 5 nicht gezeigte - Blattfeder bewirkt, welche in den Nischen 26 eingespannt ist.The control discs 7 are - as can be seen in Fig. 5 - ring-shaped educated. As is known per se, they are on the hollow axes of the Gear wheels of the differential gear tightened, but after Overcoming a certain force in the manner of a slip clutch in Rotatable circumferential direction. Tightening the control disks will caused by a - not shown in Fig. 5 - leaf spring, which in the Niches 26 is clamped.

Die Seitenansicht der Steuerscheibe 7 in Fig. 5 entspricht der Draufsicht auf das Steuerscheibenpaar in Richtung des Pfeiles 27 in Fig. 6. Fig. 6 verdeutlicht, daß die Steuerscheiben eines Steuerscheibenpaares spiegelbildlich gleich sind.The side view of the control disk 7 in FIG. 5 corresponds to the plan view the pair of control disks in the direction of arrow 27 in FIG. 6. FIG. 6 clarifies that the control discs of a pair of control discs are mirror images of the same.

Die in Fig. 7 gezeigte Steuerscheibe 7 entspricht im wesentlichen der Steuerscheibe 7 in Fig. 5. Es ist jedoch zu erkennen, daß die Ausnehmung 12 im Uhrzeigersinn verläuft. Bei der Steuerscheibe 7 in Fig. 7 handelt es sich um die zur Steuerscheibe 7 in Fig. 5 äquivalente Steuerscheibe des zweiten Steuerscheibenpaares zur Einstellung des Abschaltpunktes in der anderen Endlage der Jalousie.The control disk 7 shown in FIG. 7 corresponds essentially to that Control disc 7 in Fig. 5. However, it can be seen that the recess 12 runs clockwise. The control disk 7 in FIG. 7 is concerned around the control disk 7 equivalent to the control disk 7 in FIG second control disc pair for setting the switch-off point in the other end position of the blind.

Fig. 8 verdeutlicht in einem Ausführungsbeispiel die konstruktive Ausgestaltung der Abschaltvorrichtung, welche auf der Grundplatte 28 angeordnet ist. Es ist eine Steuerscheibe 7 mit der Ausnehmung 12 zu erkennen. Wegen des Ausschnittes in der Abdeckscheibe 29 ist die Blattfeder 30 zu erkennen, mit welcher die Steuerscheibe auf der Hohlwelle 31 festgespannt ist. Außerdem sind der Schalter 6 mit dem Schaltarm 9 und der Hebel 10 zu erkennen.8 illustrates the constructive in one embodiment Design of the switch-off device which is on the base plate 28 is arranged. There is a control disk 7 with the recess 12 too detect. Because of the cutout in the cover plate 29 is the Leaf spring 30 can be seen with which the control disc on the hollow shaft 31 is clamped. In addition, the switch 6 with the switching arm 9 and the lever 10 can be seen.

In Fig. 9 ist der Aufbau des an sich bekannten, die Steuerscheibenpaare antreibenden Differenzengetriebes mit den Zahnrädern 32, 33 und 34 zu erkennen. Die Zahnräder weisen Hohlwellen-Fortsätze auf - auf welchen - wie bereits erwähnt - die Steuerscheiben 7 festgespannt sind.
