Description

Die Erfindung betrifft einen Leistungsschalter oder ein Schütz mit einem Knebelaufsatz zur Reduzierung der Bedienkraft auf ein Bedienelement eines Schaltgeräts, wobei der Knebelaufsatz ein Gehäuse mit einer Ausnehmung aufweist.The invention relates to a circuit breaker or a contactor with a toggle attachment for reducing the operating force on an operating element of a switching device, the toggle attachment having a housing with a recess.

Schaltgeräte, insbesondere Schütze und Leistungsschalter, weisen ab einer bestimmten Baugröße eine unkomfortable Bedienung auf, weil das Bedienelement mit einem zu kleinen Hebel ausgebildet ist und folglich ein Schaltvorgang mit erhöhtem Kraftaufwand umgesetzt werden muss. Die Bedienkraft ließe sich durch eine Verlängerung des Hebels reduzieren. Jedoch ergibt sich daraus das Problem, dass das bestehende Zubehör nicht mehr verwendet werden kann, da für das Zubehör die Größe des bisherigen Bedienelements benötigt wird.Switching devices, in particular contactors and circuit breakers, have an uncomfortable operation from a certain size because the operating element is designed with a lever that is too small and consequently a switching operation must be implemented with increased effort. The operating force could be reduced by lengthening the lever. However, this gives rise to the problem that the existing accessories can no longer be used since the size of the previous operating element is required for the accessories.

Bisher wurde die aufgrund des zu kleinen Hebelarms aufzubringende erhöhte Bedienkraft akzeptiert. Eine nur bei einer bestimmten Gerätebaugröße fest konstruierte Hebelarmverlängerung war aufgrund der Verwendung gleicher Bauteile über alle Gerätebaugrößen hinweg nicht möglich.So far, the increased operating force that has to be applied due to the lever arm being too small has been accepted. A lever arm extension designed only for a certain device size was not possible due to the use of the same components across all device sizes.

In der EP 2 854 152 A1 wird ein Schaltgerät mit einer Einrichtung zum sprunghaften Einschalten offenbart. Das Schaltgerät umfasst: - eine Betätigungsmechanik, die ein Betätigungselement aufweist und über eine Übertragungsmechanik mit einem Schaltschloss in Wirkverbindung steht, welches über eine weitere Übertragungsmechanik einen Schalthebel bedient; - eine Kontaktanordnung, die ein festes Schaltstück mit Kontakten aufweist, welches gegenüber liegend zu einem beweglichen Schaltstück mit Kontakten angeordnet ist, welches in einem Kontaktschieber geführt ist. Die Einrichtung weist zum sprunghaften Einschalten ein Blockierelement auf, welches über den Schalthebel die Kontaktanordnung aus beweglichem und festem Schaltstück in einer Offen-Halteposition hält und bei einer Schnelleinschaltung die Blockade des Schalthebels aufhebt, so dass die Kontakte des beweglichen Schaltstücks sprunghaft auf den Kontakten des feste Schaltstücks landen.In the EP 2 854 152 A1 discloses a switching device with a device for suddenly switching on. The switching device comprises: an actuating mechanism, which has an actuating element and is operatively connected via a transmission mechanism to a switch lock, which operates a shift lever via a further transmission mechanism; - A contact arrangement having a fixed contact piece with contacts, which is arranged opposite to a movable contact piece with contacts, which is guided in a contact slide. For abrupt switching on, the device has a blocking element which, via the switching lever, holds the contact arrangement made up of the movable and fixed contact piece in an open holding position and at during high-speed closing, the locking of the operating lever is released, so that the contacts of the moving contact suddenly land on the contacts of the fixed contact.

Demgemäß besteht die Aufgabe der vorliegenden Erfindung darin, einen Leistungsschalter oder ein Schütz mit einem Knebelaufsatz zur Reduzierung der Bedienkraft auf ein Bedienelement eines Schaltgeräts zu schaffen, welcher über alle Baugrößen hinweg eine komfortable Bedienung des Bedienelements ermöglicht, ohne dass eine Anpassung des Zubehörs erforderlich ist.Accordingly, the object of the present invention is to create a circuit breaker or a contactor with a toggle attachment to reduce the operating force on an operating element of a switching device, which allows convenient operation of the operating element across all sizes without the need to adapt the accessories.

Diese Aufgabe wird erfindungsgemäß durch einen Leistungsschalter oder ein Schütz mit den Merkmalen des Patentanspruchs 1 gelöst. Vorteilhafte Aus- und Weiterbildungen, welche einzeln oder in Kombination miteinander eingesetzt werden können, sind der Gegenstand der abhängigen Ansprüche.According to the invention, this object is achieved by a circuit breaker or a contactor having the features of patent claim 1 . Advantageous training and developments, which can be used individually or in combination with one another, are the subject matter of the dependent claims.

Erfindungsgemäß wird diese Aufgabe durch einen Leistungsschalter oder ein Schütz mit einem Knebelaufsatz zur Reduzierung der Bedienkraft auf ein Bedienelement eines Schaltgeräts gelöst, wobei der Knebelaufsatz ein Gehäuse mit einer Ausnehmung aufweist. Die Erfindung zeichnet sich dabei dadurch aus, dass der Knebelaufsatz Befestigungsmittel aufweist, die derart ausgebildet sind, dass im Bedarfsfall eine Demontage des Knebelaufsatzes vom Bedienelement möglich ist.According to the invention, this object is achieved by a circuit breaker or a contactor with a toggle attachment for reducing the operating force on an operating element of a switching device, the toggle attachment having a housing with a recess. The invention is characterized in that the toggle attachment has fastening means which are designed in such a way that the toggle attachment can be dismantled from the operating element if necessary.

Der Knebelaufsatz des erfinderischen Leistungsschalters oder Schützes ist fest und unverlierbar vormontiert, kann jedoch kundenseitig leicht wieder demontiert werden. Das neue Bedienteil aus Bedienelement und Knebelaufsatz ist demgemäß vorzugsweise zweiteilig aufgebaut.The toggle attachment of the circuit breaker or contactor according to the invention is firmly and captively preassembled, but can be easily dismantled again by the customer. Accordingly, the new operating part consisting of the operating element and the toggle attachment is preferably constructed in two parts.

Der Knebelaufsatz des erfinderischen Leistungsschalters oder Schützes kann am bestehenden Bedienelement mittels eines Befestigungsmittels wie Schnapphaken, Rasthaken, Klemmhaken oder über eine Schraubverbindung mit einem Schraubelement fixiert werden. In der dann vorliegenden zusammengesetzten Form hat das Bedienteil vorzugsweise einen längeren Hebel. Durch Einsatz eines Schraubendrehers ist der Knebelaufsatz vom Bedienelement lösbar, so dass das übliche Bedienelement wieder verfügbar ist.The toggle attachment of the circuit breaker or contactor according to the invention can be fixed to the existing control element by means of a fastening means such as snap hooks, locking hooks, clamping hooks or via a screw connection with a screw element. In the assembled form then present, the operating part preferably has a longer lever. By using a screwdriver, the toggle attachment can be detached from the control element so that the usual control element is available again.

Für den mehrteiligen Aufbau des Bedienteils kann als Grundgerüst das bestehende Bedienelement verwendet werden. Der Knebelaufsatz weist vorzugsweise mehrere Schnapphaken und/oder Klemmhaken und/oder Rasthaken auf, die in entsprechende Nuten des Bedienelements greifen. Der Knebelaufsatz umfasst das Bedienelement vorzugsweise nicht vollständig, sondern weist im hinteren Teil, vorzugsweise der Hebelverlängerung, eine schlitzförmige Öffnung auf. In diese Öffnung kann kundenseitig ein Werkzeug, z.B. ein Schraubendreher eingeführt werden. Durch die Konturgebung des Schlitzes werden die Seitenwände des Knebelaufsatzes beim Einführen des Schraubendrehers auseinander gedrückt. Dabei werden die Schnapphaken und/oder Klemmhaken und/oder Rasthaken außer Eingriff gebracht und der Knebelaufsatz kann abgehoben werden.The existing control element can be used as the basic structure for the multi-part design of the control panel. The toggle attachment preferably has a plurality of snap hooks and/or clamping hooks and/or locking hooks which engage in corresponding grooves in the operating element. The toggle attachment preferably does not completely enclose the control element, but has a slot-shaped opening in the rear part, preferably the lever extension. A tool, eg a screwdriver, can be inserted into this opening by the customer. Due to the contouring of the slot, the side walls of the toggle attachment are pushed apart when the screwdriver is inserted. The snap hooks and/or clamping hooks and/or locking hooks are disengaged and the toggle attachment can be lifted off.

Durch den längeren Hebel des Knebelaufsatzes wird die Bedienkraft gesenkt, so dass der Kunde weniger Kraft benötigt um den Schalter einzuschalten. Durch die Demontierbarkeit des Knebelaufsatzes kann der Schalter mit dem bestehenden Zubehör verwendet werden.The operating force is reduced due to the longer lever of the toggle attachment, so that the customer needs less force to turn on the switch. Due to the fact that the toggle attachment can be dismantled, the switch can be used with the existing accessories.

Das erfinderische Konzept sieht vor, dass der Knebelaufsatz U-förmig ausgebildet ist mit zwei Schenkeln und einem die Schenkel verbindenden Mittelbereich.The inventive concept provides that the gag attachment is U-shaped with two legs and a central area connecting the legs.

Durch die U-förmige Ausbildung ergibt sich eine Ausnehmung, in welche das Bedienelement aufgenommen werden kann, so dass der Knebelaufsatz das Bedienelement umhüllt.The U-shaped design results in a recess into which the operating element can be accommodated, so that the toggle attachment encloses the operating element.

Das erfinderische Konzept sieht vor, dass die Ausnehmung im Knebelaufsatz durch die Schenkel und den Mittelbereich ausgebildet ist. Die Ausnehmung dient zur Aufnahme des Bedienelements.The inventive concept provides that the recess in the toggle attachment is formed by the legs and the central area. The recess serves to accommodate the operating element.

Eine vorteilhafte Ausgestaltung des erfindungsgemäßen Konzepts kann darin bestehen, dass am Mittelbereich und/oder an den Schenkeln Befestigungsmittel ausgebildet sind, durch welche im Bedarfsfall eine Demontage des Knebelaufsatzes vom Bedienelement möglich ist. Die Befestigungsmittel sollten dabei derart ausgebildet sein, dass der Knebelaufsatz verliersicher und demontierbar am Bedienelement fixiert ist.An advantageous embodiment of the concept according to the invention can consist in the fact that fastening means are formed on the central region and/or on the legs, by means of which a dismantling of the toggle attachment from the operating element is possible if necessary. The fastening means should be designed in such a way that the toggle attachment is captively and detachably fixed to the operating element.

Eine vorteilhafte Ausführung der Erfindung kann vorsehen, dass die Befestigungsmittel Schnapphaken und/oder Rasthaken und/oder Klemmelemente und/oder Schraubelemente sind.An advantageous embodiment of the invention can provide that the fastening means are snap hooks and/or locking hooks and/or clamping elements and/or screw elements.

Eine weitere vorteilhafte Ausführung der Erfindung kann vorsehen, dass die Demontage des Knebelaufsatzes vom Bedienelement des Schaltgeräts mittels eines Schraubendrehers vorgesehen ist.A further advantageous embodiment of the invention can provide that the dismantling of the toggle attachment from the control element of the switching device is provided by means of a screwdriver.

Eine spezielle Ausgestaltung der Erfindung kann darin bestehen, dass der Knebelaufsatz als Hebelarmverlängerung ausgebildet ist.A special embodiment of the invention can consist in the fact that the toggle attachment is designed as a lever arm extension.

Eine vorteilhafte Ausgestaltung des erfindungsgemäßen Konzepts kann darin bestehen, dass der Knebelaufsatz als Umhüllung des Bedienelements ausgebildet ist.An advantageous embodiment of the concept according to the invention can consist in the fact that the toggle attachment is designed as a casing for the operating element.

Eine Fortführung des erfindungsgemäßen Konzepts kann darin bestehen, dass der Knebelaufsatz aus Kunststoff gefertigt ist.A continuation of the concept according to the invention can consist in the fact that the toggle attachment is made of plastic.

Der Knebelaufsatz des erfinderischen Leistungsschalters oder Schützes ist U-förmig ausgebildet mit zwei Schenkeln und einen die Schenkel verbindenden Mittelbereich. Die Schenkel des Knebelaufsatzes liegen sich gegenüber, wobei sie parallel zueinander oder an den Endbereichen aufeinander zulaufend ausgebildet sein können. In die Schenkel des Knebelansatzes können Aussparungen eingearbeitet sein, um beispielsweise einen Fortsatz des Bedienelements aufzunehmen. Das Bedienelement weist einen im Wesentlichen quaderförmigen Schalthebel auf, welcher an einen vorzugsweise konzentrischen Boden angeformt ist. An den konzentrischen Boden ist entgegengesetzt zum Schalthebel ein zylinderförmiger Fortsatz ausgebildet. Die Aussparungen in den Schenkeln des Knebelaufsatzes können dazu ausgebildet sein, den konzentrischen Boden des Bedienelements aufzunehmen. Der quaderförmige Schalthebel des Bedienelements weist zwei sich vorzugsweise parallel zueinander gegenüberliegende Seitenwände auf, an welche die Schenkel des U-förmigen Knebelaufsatzes anliegen. Der quaderförmige Schalthebel weist zudem zwei weitere sich vorzugsweise parallel zueinander gegenüberliegende Seitenwände auf, wobei eine dieser Seitenwände vom Mittelbereich des Knebelaufsatzes abgedeckt wird. Die zu dieser Seitenwand parallel angeordnete Seitenwand ist durch zwei Aussparungen kürzer ausgebildet. In diese Aussparungen des quaderförmigen Schalthebels können Befestigungsmittel vorzugsweise Schnapphaken oder Klemmhaken oder Rasthaken greifen, die an den Schenkeln des Knebelaufsatzes angeordnet sind. Ebenso ist es denkbar, dass der Schalthebel des Bedienelements an der Seitenwand, die vom Mittelbereich des Knebelaufsatzes abgedeckt wird, eine Aussparung aufweist, in welche vorzugsweise Schnapphaken oder Klemmhaken oder Rasthaken des Knebelaufsatzes eingreifen können.The toggle attachment of the circuit breaker or contactor according to the invention is U-shaped with two legs and a central area connecting the legs. The legs of the toggle attachment are opposite one another, and they can be designed parallel to one another or run towards one another at the end regions. Recesses can be incorporated into the legs of the toggle attachment, for example in order to accommodate an extension of the control element. The control element has an essentially cuboid shift lever, which is formed onto a preferably concentric base. A cylindrical extension is formed on the concentric base opposite the shift lever. The recesses in the legs of the toggle attachment may be configured to receive the concentric bottom of the control. The cuboid shift lever of the operating element has two side walls which are preferably parallel and opposite one another and on which the legs of the U-shaped toggle attachment rest. The cuboid shift lever also has two further side walls which are preferably parallel to one another and are opposite one another, with one of these side walls being covered by the middle region of the toggle attachment. The side wall arranged parallel to this side wall is shorter due to two recesses. Fastening means, preferably snap hooks or clamping hooks or locking hooks, which are arranged on the legs of the toggle attachment, can engage in these recesses of the cuboid shift lever. It is also conceivable that the switching lever of the control element has a recess on the side wall, which is covered by the middle area of the toggle attachment, in which preferably snap hooks or clamping hooks or locking hooks of the toggle attachment can engage.

The toggle attachment 2 can have a significant lever extension 20 compared to the switching element 8 of the operating element 1 if the connection between the operating element 1 and the toggle attachment 2 is correspondingly reliable and secure.

In Fig. 7 ist das Ausführungsbeispiel nach Fig. 6 in einer Rückansicht dargestellt.In 7 is the embodiment according to 6 shown in a rear view.

Fig. 8 zeigt ein Bedienelement 1 mit einem Knebelaufsatz 2, der nicht nach dem erfindungsgemäßen Konzept ist, wobei aus dieser Darstellung zu entnehmen ist, dass auch das Bedienelement 1 mit Befestigungsmittel 16, vorzugsweise Schnapphaken oder Rasthaken oder Klemmhaken versehen sein kann, die in Ausnehmungen 21 in den Schenkeln 3 des Knebelaufsatzes 2 greifen. 8 shows a control element 1 with a toggle attachment 2, which is not according to the concept according to the invention, whereby it can be seen from this representation that the control element 1 can also be provided with fastening means 16, preferably snap hooks or latching hooks or clamping hooks, which are located in recesses 21 in the Grip the legs 3 of the toggle attachment 2.

Fig. 9 zeigt ein Bedienelement 1 mit einem Knebelaufsatz 2, der nicht nach dem erfindungsgemäßen Konzept ist , wobei hier der Knebelaufsatz 2 über eine Schraubverbindung, d. h. über ein Schraubelement als Befestigungsmittel 16, die über eine Bohrung 22 im Knebelaufsatz 2 umgesetzt ist, am Bedienelement 1 befestigt ist. 9 shows a control element 1 with a toggle attachment 2, which is not according to the concept according to the invention, in which case the toggle attachment 2 is fastened to the operating element 1 via a screw connection, i.e. using a screw element as a fastening means 16, which is implemented via a bore 22 in the toggle attachment 2 .

Der Knebelaufsatz des erfinderischen Schutzschalter oder Schützes zeichnet sich dadurch aus, dass das Zubehör am Bedienelement nicht angepasst werden muss. Dadurch ist es weiterhin möglich für die verschiedenen Baugrößen gleiche Bauteile zu verwenden. Durch den Knebelaufsatz hat der Kunde beim Bedienen des Schalters einen höheren Komfort bzw. ein wertigeres Empfinden. Die Reduzierung der Bedienkraft am Schalter ist durch den Knebelaufsatz in einer kostengünstigen Maßnahme umgesetzt worden, die im Bedarfsfall vom Kunden durch einfache Demontage des Knebelaufsatzes rückgängig gemacht werden kann.The toggle attachment of the inventive circuit breaker or contactor is characterized in that the accessories on the control element do not have to be adjusted. This means that it is still possible to use the same components for the different sizes. Thanks to the toggle attachment, the customer has greater convenience and a more valuable feeling when operating the switch. The reduction in the operating force on the switch has been implemented as a cost-effective measure using the toggle attachment, which can be reversed by the customer if necessary by simply removing the toggle attachment.
