Abstract

The invention relates to a rotary drive (1) for a control unit, having a rotary spring (5) which is used both for return motion and for latching. The rotary spring (5) is mounted concentrically in the link (3) of the rotary drive (1) and is stressed inwards by an outer guide (10) which is formed by the collar (2). The rotary spring end (6,7), which is deflected by a cutout (14) in the link (3), latches in a latching depression (11) in the collar (2). When rotated in the opposite direction, the latching is overcome via a tangential return surface (8) on the cutout (14). <IMAGE>

Description

Die Erfindung betrifft einen Drehantrieb für einen elektrischen Schalter, der eine Rosette, eine drehbare Kulisse und einen Schieber umfaßt.The invention relates to a rotary drive for an electrical switch, which comprises a rosette, a rotatable link and a slide.

Derartige Drehantriebe sind auf dem Elektromarkt für Niederspannungsschaltgerate erhältlich und gehören zum Stand der Technik. Bei diesen wird durch Drehbewegung eines Knebels vor der Fronttafel in axialer Richtung über eine Kulisse ein Schieber ausgefahren, der ein Schaltelement an der Rückseite des Schalters betätigt. Der Drehantrieb ist dabei mit einem Knebel oder Schloß als Handhabe mit Raster- oder Tasterfunktion ausgeführt. Die Rückstellung des Drehantriebs bei Freigabe der Handhabe wird durch Federkraft in axialer Richtung auf den Schieber bewirkt.Such rotary actuators are available on the electrical market for low-voltage switching devices and are part of the prior art. In these, a slider is extended by rotating a toggle in front of the front panel in the axial direction, which actuates a switching element on the rear of the switch. The rotary actuator is designed with a knob or lock as a handle with a grid or button function. The reset of the rotary drive when the handle is released is effected by spring force in the axial direction on the slide.

Eine derartige Ausführungsform ist jedoch mit folgenden Nachteilen verbunden. Zur sicheren Rückfuhrung in die Nullstellung ist eine relativ hohe Federkraft und Steilheit von Gewindesegmenten an der Kulisse erforderlich. Dies führt bei Betätigung, insbesondere bei Bestückung mit mehreren Schaltelementen, zu Schwergängigkeit bis hin zur Selbsthemmung, was durch Fetten zu verhindern versucht wird. Zur Funktion "Tasten" muß die Aufgleitbewegung der Schieber noch auf der Schräge der Gewindesegmente gestoppt werden. Dadurch wirken sich Drehwinkeltoleranzen des Anschlages stark auf den Hub an den Schaltelementen aus. Außerdem erweist es sich bei dieser Ausführung als nachteilig, daß bei einem beleuchtbaren Drehantrieb der für die Lampe und deren Auswechselung von der Betätigerseite aus notwendige freie Querschnitt durch die Feder eingeschränkt wird.However, such an embodiment has the following disadvantages. A relatively high spring force and steepness of thread segments on the link are required for a safe return to the zero position. When actuated, particularly when equipped with several switching elements, this leads to stiffness and even self-locking, which is attempted to be prevented by greasing. For the "buttons" function, the sliding movement of the slide must still be stopped on the slope of the thread segments. As a result, the angle of rotation tolerances of the stop have a strong effect on the stroke on the switching elements. In addition, it proves to be a disadvantage in this embodiment that the free cross section necessary for the lamp and its replacement from the actuator side is restricted by the spring in the case of an illuminable rotary drive.

Zwar gehört es zum Stand der Technik die Rückstellung der Schieber durch eine Drehrückführung mittels einer Drehfeder zu bewerkstelligen. Zur Verwirklichung eines rastenden Antriebs ist jedoch eine Zusatzrastung erforderlich.It is part of the state of the art to reset the slide by means of a rotary return using a torsion spring to accomplish. However, an additional detent is required to realize a detenting drive.

Daher liegt der Erfindung die Aufgabe zugrunde, einen elektrischen Schalter der oben genannten Art zu schaffen, bei dem die Verrastung über die Drehfeder erfolgt. Die Aufgabe wird gelöst durch einen Schalter mit dem Merkmalen gemäß Anspruch 1. Als besonders vorteilhaft erweist sich eine Ausführungsform, bei der die Drehfeder mindestens eine kreisförmige Windung aufweist und die beiden Federenden die Kreisform tangential bzw. auf einem Radius nach außen bis auf einen bestimmten Abstand verlassen, dann gegenläufig abgebogen sind und als zwei parallel zur Drehfederachse verlaufende Drahtstücke enden.Therefore, the invention has for its object to provide an electrical switch of the above type, in which the locking takes place via the torsion spring. The object is achieved by a switch with the features according to claim 1. An embodiment in which the torsion spring has at least one circular turn and the two spring ends have the circular shape tangentially or on a radius to the outside up to a certain distance proves to be particularly advantageous leave, then turned in opposite directions and end up as two pieces of wire running parallel to the torsion spring axis.

Weitere vorteilhafte Weiterbildungen der Erfindung sind den Unteransprüchen 3 bis 11 zu entnehmen.Further advantageous developments of the invention can be found in subclaims 3 to 11.

Ein Ausführungsbeispiel der Erfindung wird im folgenden anhand einer Zeichnung naher erläutert. Es zeigen:

FIG 1
Eine Explosionsdarstellung des erfindungsgemäßen Drehantriebs,
FIG 2
einen Querschnitt durch den Drehantrieb,
FIG 3
eine perspektivische Ansicht des Drehantriebs im Aufriß.
An embodiment of the invention is explained in more detail below with reference to a drawing. Show it:
FIG. 1
An exploded view of the rotary drive according to the invention,
FIG 2
a cross section through the rotary drive,
FIG 3
a perspective view of the rotary drive in elevation.

In FIG 1 ist eine Explosionsdarstellung des erfindungsgemäßen Drehantriebs 1 dargestellt, der eine Rosette 2, zwei Schieber 4, eine Kulisse 3, eine Drehfeder 5, eine Abdeckung 9, eine Dichtung 15, einen Frontring 16 und einen Knebel 17 umfaßt. Die Darstellung verdeutlicht die Einbaulage der genannten Komponenten.1 shows an exploded view of the rotary drive 1 according to the invention, which comprises a rosette 2, two slides 4, a link 3, a torsion spring 5, a cover 9, a seal 15, a front ring 16 and a toggle 17. The illustration shows the installation position of the components mentioned.

Die Drehfeder 5 besteht aus mehreren aneinanderliegenden Windungen 12 gleichen Durchmessers. Beide Enden 6,7 der Drehfeder 5 verlassen den Durchmesser tangential bzw. auf einem Radius nach außen bis auf einen bestimmten Abstand, sind dann gegenläufig rechtwinklig abgebogen und enden als zwei parallel zur Wicklungsachse in gleicher Höhe verlaufende gerade Drahtstücke. Die Windungen 12 der Drehfeder 5 umschließen mit geringem Spiel eine durch die Abdeckung 9 gebildete Innenführung, die allerdings auch durch die Kulisse 3, in der die Drehfeder 5 konzentrisch gelagert ist, gegeben sein kann.The torsion spring 5 consists of several adjacent turns 12 of the same diameter. Both ends 6, 7 of the torsion spring 5 leave the diameter tangentially or on a radius to the outside up to a certain distance, are then bent in opposite directions at right angles and end up as two straight pieces of wire running parallel to the winding axis at the same height. The windings 12 of the torsion spring 5 enclose, with little play, an inner guide formed by the cover 9, which, however, can also be provided by the link 3, in which the torsion spring 5 is mounted concentrically.

FIG 2 zeigt in einer Querschnittsdarstellung die Position der Drehfeder 5 in der unbetätigten Nullstellung und in der über das Federende 7 verrasteten Stellung. Die Rosette 2 weist eine weitgehend ringförmige Fläche mit einem stufenförmigen Absatz 10 und einem Bereich 19 mit Durchmesserverringerung auf, der durch zwei radial verlaufende Übergänge 18 zum Absatz 10 hin begrenzt ist, zu deren beiden Seiten in gleichem Winkelabstand im stufenförmigen Absatz 10 jeweils eine Rastfalle 11 liegt.2 shows a cross-sectional view of the position of the torsion spring 5 in the unactuated zero position and in the position locked over the spring end 7. The rosette 2 has a largely ring-shaped surface with a step-shaped shoulder 10 and an area 19 with a diameter reduction, which is delimited by two radially extending transitions 18 to the shoulder 10, on each side of which a latching catch 11 in the step-shaped shoulder 10 at the same angular distance lies.

Die Kulisse 3 ist weitgehend innerhalb der Rosette 2 angeordnet und trägt innerhalb des dem Knebel 17 zugewandten in Form eines Kreisrings ausgebildeten Endbereiches die Drehfeder 5. Der kreisringförmige Endbereich ist mit zwei Ausschnitten 14 im gleichen Winkelabstand, wie die oben erwähnten Übergänge 18 solcher Art versehen, daß ebenfalls radial verlaufende Übergänge 20 der Ausschnitte 14 sich in der Nullstellung des Drehantriebs mit den oben erwähnten Übergängen 18 der Rosette 2 in Überdeckung befinden.The backdrop 3 is largely arranged within the rosette 2 and carries the torsion spring 5 within the end region which is designed in the form of an annulus and faces the knob 17. The annular end region is provided with two cutouts 14 at the same angular distance as the above-mentioned transitions 18 of this type. that also radially extending transitions 20 of the cutouts 14 are in overlap with the above-mentioned transitions 18 of the rosette 2 in the zero position of the rotary drive.

Eine konzentrische Außenführung mit entsprechendem Durchmesser spannt die flügelartig abstehenden Federenden 6,7 nach innen. Die Außenfuhrung ist axial in halber Federhöhe zweigeteilt, in den als Absatz 10 der Rosette 2 ausgebildeten feststehenden Teil und den als kreisförmigen Endbereich der Kulisse 3 drehbaren Teil, der mit dem Knebel 17 als Handhabe verbunden ist.A concentric outer guide with a corresponding diameter clamps the spring ends 6,7 projecting like wings inwards. The outer guide is axially divided in two at half the height of the spring, into the fixed part formed as a shoulder 10 of the rose 2 and the part which can be rotated as a circular end region of the link 3 and which is connected to the knob 17 as a handle.

Die vor dem Einsetzen in Öffnungsrichtung, d.h. durch Durchmesservergrößerung vorgespannte Drehfeder 5 stützt sich mit ihren Federenden 6,7 an den radial verlaufenden Übergängen 18,20 ab. Bei Auslenkung des Drehantriebs entgegen dem Uhrzeigersinn gemäß FIG 2 liegt das rechte Federende 6 am Übergang 18 fest an, während das linke Federende 7 durch den Übergang 20 am linken Ausschnitt 14 der Kulisse 3 mitgeführt wird und sich am Absatz 10 der Rosette 2 abstützt. Damit ist die selbsttätige Rückkehr, d.h. die Funktion "Tasten" gewährleistet.The prior to insertion in the opening direction, i.e. Tension spring 5 biased by increasing the diameter is supported with its spring ends 6, 7 on the radially extending transitions 18, 20. When the rotary drive is deflected counterclockwise according to FIG. 2, the right spring end 6 is firmly in contact with the transition 18, while the left spring end 7 is carried along by the transition 20 on the left cutout 14 of the link 3 and is supported on the shoulder 10 of the rosette 2. This is the automatic return, i.e. the function "buttons" ensures.

Die erwähnte Rastfalle 11 ist zur Erzielung der "rastenden" Funktion vorgesehen. Durch die Vorspannung der Federenden 6,7, die durch die "öffnende" Betätigung verstärkt wird, rastet das ausgelenkte Federende 7 in die in der Endstellung deckungsgleichen Fallen, d.h. in die Rastfalle 11 der Rosette 2 und in den Ausschnitt 14 der Kulisse 3 ein. Damit ist die Rückführung zuverlässig blockiert, da die Raststabilität mit der Federspannung steigt.The aforementioned latch 11 is provided to achieve the "latching" function. Due to the pretension of the spring ends 6, 7, which is reinforced by the "opening" actuation, the deflected spring end 7 snaps into the cases which are congruent in the end position, i.e. in the latch 11 of the rosette 2 and in the cutout 14 of the backdrop 3. This reliably blocks the return because the locking stability increases with the spring tension.

Beim manuellen Ausrasten, d.h. dem Rückstellen des Drehantriebs nach Überwinden eines Kraftberges, wird das eingerastete Federende 7 von der tangentialen Rückführungsfläche 8 in dem Ausschnitt 14 nach innen geschoben, worauf nach Verlassen der feststehenden Rastfalle 11 die selbsttätige Rückführung in die Nullstellung erfolgt.With manual disengagement, i.e. the return of the rotary drive after overcoming a power mountain, the spring end 7 is pushed inwards by the tangential return surface 8 in the cutout 14, whereupon after leaving the fixed latch 11 the automatic return to the zero position takes place.

Wie aus der FIG 2 ersichtlich, kann die Drehfeder 5 in eine als auch in zwei Richtungen zur Erzielung eines Zweistellungsantriebes ausgelenkt werden. Bei Auslenkung der Drehfeder 5 in Gegenrichtung zu oben beschriebener Richtung sind aufgrund des völlig symmetrischen Aufbaus lediglich die Funktionen der Federenden 6,7 vertauscht, d.h. das Federende 7 liegt fest an dem Übergang 18 der Rosette 2 an, und das Federende 6 wird durch die Kulisse 3 mitgenommen.As can be seen from FIG. 2, the torsion spring 5 can be deflected in one as well as in two directions in order to achieve a two-position drive. When the torsion spring 5 is deflected in the opposite direction to the direction described above, only the functions of the spring ends 6, 7 are interchanged due to the completely symmetrical structure, ie the spring end 7 lies firmly against the transition 18 of the rosette 2, and the spring end 6 is through the backdrop 3 taken away.

Die Verrastung kann bedarfsweise durch Einsetzen von entsprechend geformten Füllstücken in die Rastfallen 11 aufgehoben werden. Derartige Füllstücke können auch zur Drehbegrenzung verwendet werden, so daß alle Drehantriebsvarianten möglich sind.If necessary, the latching can be canceled by inserting appropriately shaped filler pieces into the latching latches 11. Filling pieces of this type can also be used to limit the rotation, so that all rotary drive variants are possible.

Die beschriebene erfindungsgemäße Ausführungsform weist bei entsprechender Dimensionierung und Anordnung der Drehfeder 5 einen großen freien Querschnitt 13 auf, der nur vom vorgegebenen Außendurchmesser und den erforderlichen Wandstärken von Rosette 2 und Kulisse 3 bestimmt wird. Damit ist die Realisierung von beleuchtbaren Drehantrieben wesentlich verbessert, da nun genug Raum für die Lampe und deren Auswechselung zur Verfügung steht.The described embodiment according to the invention, with appropriate dimensioning and arrangement of the torsion spring 5, has a large free cross section 13, which is determined only by the predetermined outer diameter and the required wall thicknesses of the rosette 2 and the backdrop 3. The realization of illuminable rotary drives has been significantly improved since there is now enough space available for the lamp and its replacement.

In FIG 3 ist ein Aufriß des Drehantriebs 1 perspektivisch dargestellt, der die Anordnung der zuvor genannten Komponenten zueinander wiedergibt. Die Drehfeder 5 befindet sich hier in der Rastposition, denn ihr im Ausschnitt 14 steckendes Federende 6 oder 7 ragt an der Unterseite über den Außenrand der Kulisse 3 hinaus, wo der hier nicht dargestellte Teil der Rosette 2 mit der Rastfalle 11 (siehe FIG 2) liegt.In Figure 3, an elevation of the rotary drive 1 is shown in perspective, which shows the arrangement of the aforementioned components to each other. The torsion spring 5 is here in the latching position, because its spring end 6 or 7, which is in the cutout 14, projects on the underside beyond the outer edge of the link 3, where the part of the rosette 2 (not shown here) with the latching latch 11 (see FIG. 2) lies.
