Definitions
- the invention relates to a changeover device according to the preamble of claim 1.
- switches that are suitable for various uses. However, it may then be necessary to limit a switch, which is versatile in itself, to only one of its possible uses, that is to say to set the switch to its respective use.
- the invention has for its object to provide an economically feasible changeover device which is simple in construction, space-saving and easy to operate.
- the latch which can be operated from outside the switch housing, enables the changeover to be carried out simply and quickly.
- the bolt can be rotated about an axis that is vertical to the housing wall also allows simple operation, but at the same time prevents the bolt from being inadvertently changed, particularly when the bolt arrangement is preferably recessed.
- the locking points provided on the housing wall and the Locking points of the spring clip of the bolt can be advantageously carried out using tools. They can be automatically engaged with each other during assembly, so to speak. Their number is limited at most by the dimensioning, so that more than two positions can be locked.
- Housing wall with opening and latch can be made in one piece from plastic in conventional plastic precision, which is very economical.
- the bolt preferably has a continuous hub, on the outer side of which the spring clip is molded, while the guide ring parts are molded on the central part of the hub.
- two spring clips which lie opposite one another in a common plane and are each partially separated from the hub by an arcuate window, form a locking ring which has the largest diameter of the bolt.
- This locking ring is preferably embedded in a ring-like largest opening part of the housing wall opening and lies over an annular locking base.
- the latching base delimits the largest part of the opening radially towards the inside and carries the associated latching points, which are preferably depressions.
- the locking points of the locking ring which are preferably projections, lie opposite these locking recesses.
- the bayonet claws preferably project axially and radially outward from the latching base toward the axis of rotation in the curved windows of the latching ring and radially overlap the guide ring parts of the bolt.
- the guide ring parts form a guide ring, which has a smaller diameter than the locking ring, and rests on a guide base, which has a central opening Part of the wall opening is axially limited inwards.
- limits are also provided on the locking base, which limits the locking points of the spring clips as end stops when the bolt is turned serve. These end stops can be chamfered on one side and steep on the other side, so that they can be run over when the bolt is screwed into the opening, but their steep flank opposes the bolt being unscrewed.
- This embodiment is particularly advantageously designed such that an annular groove closed by the end stops is provided on the latching base, which annular groove is extended in places by the latching points, the spring clips then having projecting latching cams.
- the wall opening preferably has a smallest opening in which the innermost hub part designed as a centering part sits. This not only results in a good centering of the bolt, but also a good closure of the opening.
- this innermost and smallest diameter opening part should be as round as possible so that it can optimally fulfill its centering and closing function, but to make the bayonet claws easier, it may be necessary to provide recesses for the tool therein, which in turn can be closed by the guide ring parts .
- a point of attack for a tool for example a screwdriver
- a tool for example a screwdriver
- An adjustment extension e.g. an eccentric pin and the like can be provided, which protrudes into the switch housing and can be brought about by turning the bolt. He can e.g. enable or cancel a trip position, but also perform other functions.
- the changeover device can be used for a large number of different electrical switches, for example for motor circuit breakers, circuit breakers and circuit breakers.
- the latch is very short and easy to form in plastic and therefore the device can find space within a housing wall thickness and can only reach into the inside of the switch with an actuation extension, while everything closes smoothly on the outside.
- the latch can be inserted from the outside into the opening of the housing wall, which makes assembly very easy. Only a corresponding opening needs to be provided in the housing wall, which is easily possible in the course of molding the housing wall from plastic.
- the bolt closes the opening in the housing wall.
- the changeover device can also be designed in a simple manner for straight-line movement.
- the bolt is designed as a slide with a spring clip running parallel to the direction of movement and the housing wall with bayonet claws running parallel to the direction of movement.
- the latch 4 is inserted into the opening 3 as follows: - The bolt is partially pushed into the opening 3 in the axial direction. - Now turn the bolt around the axis of rotation A counterclockwise until the openings 42l are exactly above the bayonet claws 3O5. This rotational position can be seen from the comparison of floors 6O and 63 of FIG. 6. - The bolt can now be fully inserted axially, with the bayonet claws 305 passing through the openings 42l of the guide ring 42 into the windows 410. - Now you can turn the bolt counterclockwise further about the axis A, the guide ring parts 42 resting on the guide base 3ll sliding under the holding surfaces 306 of the bayonet claws 305.

Description
Die Erfindung betrifft eine Umstellvorrichtung nach dem Oberbegriff des Anspruch l.The invention relates to a changeover device according to the preamble of claim 1.
Zur Steigerung der Stückzahlen bei der Herstellung und zur Vereinfachung der Lagerhaltung ist es erwünscht, Schalter zu bauen, die für verschiedene Verwendungsmöglichkeiten geeignet sind. Es kann dann aber erforderlich werden, einen an sich vielseitig verwendbaren Schalter auf nur eine seiner Verwendungsmöglichkeit zu begrenzen, also den Schalter auf seine betreffende Verwendung einzustellen.In order to increase the number of pieces in the manufacture and to simplify the storage, it is desirable to build switches that are suitable for various uses. However, it may then be necessary to limit a switch, which is versatile in itself, to only one of its possible uses, that is to say to set the switch to its respective use.
Der Erfindung liegt die Aufgabe zugrunde eine wirtschaftlich vorteilhaft realisierbare Umstellvorrichtung zu schaffen, welche einfach im Aufbau, platzsparend und einfach betätigbar sein soll.The invention has for its object to provide an economically feasible changeover device which is simple in construction, space-saving and easy to operate.
Zur Lösung dieser Aufgabe wird die im Anspruch l gekennzeichnete Umstellvorrichtung vorgeschlagen.To achieve this object, the changeover device characterized in claim 1 is proposed.
Der von ausserhalb des Schaltergehäuses betätigbare Riegel erlaaubt es, die Umstellung einfach und rasch vorzunehmen.The latch, which can be operated from outside the switch housing, enables the changeover to be carried out simply and quickly.
Die Drehbarkeit des Riegels um eine zur Gehäusewand vertikale Achse erlaubt zwar ebenfalls eine einfache Bedienung, verhindert aber gleichzeitig ein ungewolltes Umstellen des Riegels, besonders bei bevorzugterweise versenkter Riegelanordnung.The fact that the bolt can be rotated about an axis that is vertical to the housing wall also allows simple operation, but at the same time prevents the bolt from being inadvertently changed, particularly when the bolt arrangement is preferably recessed.
Durch das bajonettverschlussartige Ineinandergreifen der Führungsringteile des Riegels und der Bajonettklauen der Gehäusewand ist es möglich den Riegel von aussen in die Oeffnung der Gehäusewand einzusetzen, was montagetechnisch sehr vorteilhaft ist und selbst Automatenmontage zulässt.Due to the bayonet-type interlocking of the guide ring parts of the bolt and the bayonet claws of the housing wall, it is possible to insert the bolt from the outside into the opening of the housing wall, which is very advantageous from an assembly point of view and even allows automatic assembly.
Die an der Gehäusewand vorgesehenen Raststellen und die Raststellen des Federbügels des Riegels lassen sich werkzeugtechnisch vorteilhaft ausführen. Sie können bei der Montage sozusagen selbsttätig miteinander in Eingriff gebracht werden. Ihre Anzahl ist höchstens durch die Dimensionierung begrenzt, so dass mehr als zwei Positionen gerastet werden können.The locking points provided on the housing wall and the Locking points of the spring clip of the bolt can be advantageously carried out using tools. They can be automatically engaged with each other during assembly, so to speak. Their number is limited at most by the dimensioning, so that more than two positions can be locked.
Trotzdem ist alles sehr klein dimensionierbar und vorzugsweise auf die normale Dicke einer Gehäusewand beschränkbar.Nevertheless, everything can be dimensioned very small and preferably limited to the normal thickness of a housing wall.
Gehäusewand mit Oeffnung und Riegel lassen sich einstückig aus Kunststoff in herkömmlicher Kunststoffpräzision fertigen, was sehr wirtschaftlich ist.Housing wall with opening and latch can be made in one piece from plastic in conventional plastic precision, which is very economical.
Der Riegel weist vorzugsweise eine durchgehende Nabe auf, an deren äusserer Seite der Federbügel angeformt ist, während am mittleren Teil der Nabe die Führungsringteile angeformt sind.The bolt preferably has a continuous hub, on the outer side of which the spring clip is molded, while the guide ring parts are molded on the central part of the hub.
Vorteilhaft bilden zwei Federbügel, welche sich in einer gemeinsamen Ebene gegenüberliegen und je durch ein bogenförmiges Fenster von der Nabe teilweise getrennt sind, einen Rastring, welcher den grössten Durchmesser des Riegels aufweist. Dieser Rastring ist vorzugsweise in einem ringartigen grössten Oeffnungsteil der Gehäusewand-Oeffnung eingebettet und liegt über einem ringförmigen Rastboden. Der Rastboden begrenzt den grössten Oeffnungsteil radial gegen innen und trägt die zugehörigen Raststellen, die vorzugsweise Vertiefungen sind. Die Raststellen des Rastringes, die vorzugsweise Vorsprünge sind, liegen diesen Rastvertiefungen gegenüber. Die Bajonettklauen stehen vorzugsweise vom Rastboden nach aussen axial und radial zur Drehachse hin ab in den bogenförmigen Fenstern des Rastringes und übergreifen dabei radial die Führungsringteile des Riegels. Die Führungsringteile bilden dabei einen Führungsring, welcher einen kleineren Durchmesser als der Rastring aufweist, und auf einem Führungsboden aufliegt, welcher einen mittleren Oeff nungsteil der Wand-Oeffnung axial nach innen begrenzt.Advantageously, two spring clips, which lie opposite one another in a common plane and are each partially separated from the hub by an arcuate window, form a locking ring which has the largest diameter of the bolt. This locking ring is preferably embedded in a ring-like largest opening part of the housing wall opening and lies over an annular locking base. The latching base delimits the largest part of the opening radially towards the inside and carries the associated latching points, which are preferably depressions. The locking points of the locking ring, which are preferably projections, lie opposite these locking recesses. The bayonet claws preferably project axially and radially outward from the latching base toward the axis of rotation in the curved windows of the latching ring and radially overlap the guide ring parts of the bolt. The guide ring parts form a guide ring, which has a smaller diameter than the locking ring, and rests on a guide base, which has a central opening Part of the wall opening is axially limited inwards.
Dadurch kann an sich eine stabile Lage des Riegels sichergestellt werden, und man kann gleichzeitig den Einbau des Riegels von aussen sehr erleichtern.In this way, a stable position of the bolt can be ensured, and at the same time the installation of the bolt from the outside can be made very easy.
Um dieses Zusammenbauen besonders einfach zu machen und um gleichzeitig zu verhindern, dass der eingesetzte Riegel wieder leicht herausgedreht werden kann, ist es bevorzugt, wenn am Rastboden ausser den Raststellen auch Begrenzungen vorgesehen sind, welche letztere den Raststellen der Federbügel als Endanschläge beim Drehen des Riegels dienen. Diese Endanschläge können dabei einseitig geschrägt und auf der anderen Seite steil ausgeführt sein, so dass sie zwar beim Eindrehen des Riegels in die Oeffnung überfahren werden können, aber ihre steile Flanke dem Herausdrehen des Riegels entgegenstellen.In order to make this assembly particularly simple and at the same time to prevent the inserted bolt from being easily unscrewed again, it is preferred if, in addition to the locking points, limits are also provided on the locking base, which limits the locking points of the spring clips as end stops when the bolt is turned serve. These end stops can be chamfered on one side and steep on the other side, so that they can be run over when the bolt is screwed into the opening, but their steep flank opposes the bolt being unscrewed.
Diese Ausführungsform ist besonders vorteilhaft so ausgebildet, dass am Rastboden eine durch die Endanschläge verschlossene Ringnut vorgesehen ist, welche Ringnut stellenweise durch die Raststellen erwietert ist, wobei dann die Federbügel vorstehende Rastnocken haben.This embodiment is particularly advantageously designed such that an annular groove closed by the end stops is provided on the latching base, which annular groove is extended in places by the latching points, the spring clips then having projecting latching cams.
Zuinnerst hat die Wand-Oeffnung vorzugsweise eine kleinste Oefnung in welcher der als Zentrierteil ausgebildete innerste Nabenteil sitzt. Das ergibt nicht nur eine gute Zentrierung des Riegels, sondern auch einen guten Verschluss der Oeffnung. An sich sollte dieser innerste und im Durchmesser kleinste Oeffnungsteil möglichst rund sein, damit er seine Zentrier- und Schliessfunktion bestens erfüllen kann, aber zur leichteren Ausbildung der Bajonettklauen kann es erforderlich sein Ausnehmungen für das Werkzeug darin vorzusehen, die ihrerseits durch die Führungsringteile verschlossen werden können.At the inside, the wall opening preferably has a smallest opening in which the innermost hub part designed as a centering part sits. This not only results in a good centering of the bolt, but also a good closure of the opening. As such, this innermost and smallest diameter opening part should be as round as possible so that it can optimally fulfill its centering and closing function, but to make the bayonet claws easier, it may be necessary to provide recesses for the tool therein, which in turn can be closed by the guide ring parts .
Am äussersten Ende der Nabe kann man eine Angriffsstelle für ein Werkzeug, z.B. einen Schraubenzieher, vorsehen, wodurch jede ungewollte Fehlbedienung des Riegels vermeidbar wird, insbesondere, wenn er vorzugsweise ganz in der Wand versenkt ist.At the extreme end of the hub, a point of attack for a tool, for example a screwdriver, can be provided, as a result of which any undesired incorrect operation of the bolt can be avoided is, especially if it is preferably completely sunk into the wall.
Am innersten Riegelende kann ein Verstellfortsatz, z.B. ein exzentrischer Stift und dergleichen vorgesehen sein, welcher in das Schaltergehäuse hineinragt und durch Drehen des Riegels das Umstellen bewerkstelligen kann. Er kann z.B. eine Trip-Stellung ermöglichen oder aufheben, aber auch andere Funktionen erfüllen.An adjustment extension, e.g. an eccentric pin and the like can be provided, which protrudes into the switch housing and can be brought about by turning the bolt. He can e.g. enable or cancel a trip position, but also perform other functions.
Es ist also bevorzugt möglich den Riegel bajonettverschlussartig von aussen in die Oeffnung der Wand einzusetzen und ihn dort gesichert drehbar zu belassen.It is therefore preferably possible to insert the bolt from the outside into the opening of the wall in the manner of a bayonet lock and to leave it securely rotatable there.
Demnach ist es durch die Erfindung auf einfache Weise möglich folgende Vorteile zu erzielen:
- Die Umstellvorrichtung ist für eine Vielzahl von verschiedenen elektrischen Schaltern anwendbar, beispielsweise für Motorschutzschalter, Leitungsschutzschalter und Leistungsschalter.
- Der Riegel ist sehr kurz und einfach in Kunststoff ausbildbar und daher kann die Vorrichtung innerhalb einer Gehäusewanddicke Platz finden und nur mit einem Betätigungsfortsatz ins Schalterinnere reichen, während aussen alles glatt abschliesst.
- Der Riegel kann von aussen in die Oeffnung der Gehäusewand eingesetzt werden, was eine sehr einfach Montage ergibt.
-In der Gehäusewand braucht nur eine entsprechende Oeffnung vorgesehen zu werden, was im Zuge des Formens der Gehäusewand aus Kunststoff leicht möglich ist.
- Der Riegel verschliesst die Oeffnung in der Gehäusewand.
Auf einfache Weise kann die Umstellvorrichtung auch für geradlinige Bewegung ausgestaltet werden. Der Riegel wird dabei als Schieber mit einem parallel zur Bewegungsrichtung verlaufenden Federbügel und die Gehäusewand mit parallel zur Bewegungsrichtung verlaufenden Bajonettklauen ausgebildet.Accordingly, the invention enables the following advantages to be achieved in a simple manner:
- The changeover device can be used for a large number of different electrical switches, for example for motor circuit breakers, circuit breakers and circuit breakers.
- The latch is very short and easy to form in plastic and therefore the device can find space within a housing wall thickness and can only reach into the inside of the switch with an actuation extension, while everything closes smoothly on the outside.
- The latch can be inserted from the outside into the opening of the housing wall, which makes assembly very easy.
Only a corresponding opening needs to be provided in the housing wall, which is easily possible in the course of molding the housing wall from plastic.
- The bolt closes the opening in the housing wall.
The changeover device can also be designed in a simple manner for straight-line movement. The bolt is designed as a slide with a spring clip running parallel to the direction of movement and the housing wall with bayonet claws running parallel to the direction of movement.

Das Einsetzen des Riegels 4 in die Oeffnung 3 wird wie folgt vorgenommen:
- Der Riegel wird in axialer Richtung teilweise in die Oeffnung 3 eingeschoben.
- Nun dreht man den Riegel um die Drehachse A im Gegenuhrzeigersinn, bis sich die Durchbrüche 42l genau über den Bajonettklauen 3O5 befinden. Diese Drehlage ist aus der Gegenüberstellung der Etagen 6O und 63 der Fig. 6 ersichtlich.
- Nun kann der Riegel axial ganz eingeschoben werden, wobei die Bajonettklauen 3O5 durch die Durchbrüche 42l des Führungsrings 42 in die Fenster 4ll treten.
- Nun kann man den Riegel im Gegenuhrzeigersinn weiter um die Achse A drehen, wobei die am Führungsboden 3ll aufliegenden Führungsringteile 42 unter die Halteflächen 3O6 der Bajonettklauen 3O5 gleiten.
- Beim Weiterdrehen um die Achse A im Gegenuhrzeigersinn gleiten die Rastnocken 4l3 über die Schrägungen 3O7O aus den Einfahrmulden 3O7 über die Begrenzungen 3O4 in die dazu nächstgelegenen Rastvertiefungen 3O2, wobei die Federbügelteile 4l2 axial nach aussen gelenkt werden und dann wieder nach innen federn. Die am Ende dieser Drehbewegung erreichte Drehlage ist aus der Gegenüberstellung der Etagen 6l und 63 der Fig. 6 ersichtlich. Diese Drehlage ist ausserdem den Fig. 2 bis 5 zugrundegelegt. Aus dieser Drehlage kann man den Riegel 4 nicht im Uhrzeigersinn drehen, weil die Begrenzungen 3O4 die Rastnocken 4l3 nich durchlassen. Der Riegel ist also gegen Herausnehmen gesichert. Nur wenn man mit einem Werkzeug beide Federbügelteile 4l2 axial nach aussen auslenken würde wäre ein willentliches Herausnehmen des Riegels möglich.
- Um aus dieser ersten Raststellung, welche der Gegenüberstellung der Etagen 6l und 63 der Fig. 6 entspricht, in die andere Raststellung, welche der Gegenüberstellung der Etagen 62 und 63 der Fig. 6 entspricht, zu gelangen, dreht man den Riegel 4 weiter im Gegenuhrzeigersinn. Dabei gleiten die Rastnocken 4l3 über die Schrägungen 3O2O aus den Rastvertiefungen 3O2 und rasten dann in den zweiten Rastvertiefungen 3O2 ein, wobei die Federbügelteile 4l2 eine axiale Federbewegung ausführen.
- Jetzt kann durch Drehen des Riegels 4 im Uhrzeigersinn wieder die vorhergehende Raststellung (entsprechend der Gegenüberstellung der Etagen 6l und 63 der Fig. 6) erreicht werden, und so auch weiter hin und her geschaltet werden.The latch 4 is inserted into the

- When turning further around the axis A in a counterclockwise direction, the locking cams 4l3 slide over the bevels 3O7O from the entry recesses 3O7 over the boundaries 3O4 into the nearest locking recesses 3O2, the spring clip parts 4l2 being axially steered outwards and then springing inwards again. The rotational position reached at the end of this rotary movement can be seen from the comparison of

Einfachheitshalber sind hier nur zwei Raststellungen dargestellt und besprochen worden, aber es wären auch weitere Raststellungen möglich.For the sake of simplicity, only two rest positions have been shown and discussed here, but further rest positions would also be possible.
Der exzentrisch am Zentrierteil 43 angeformte Verstellfortsatz 44 führt bei allen Drehbewegungen des Riegels 4 eine Exzenterbewegung im Inneren des Schalters aus, welche zum Umstellen ausgenützt werden kann.The
