Es sind Schaltgeräte bekannt, welche Schalthebel zum manuellen Schließen und/oder Öffnen von Schaltkontakten aufweisen. Diese Schalthebel sind im Betrieb vielfältigen Belastungen ausgesetzt. Neben der manuellen Betätigung müssen dieses Schalthebel auch den Belastungen durch ein automatisches Einschaltgerät standhalten. Durch die Kräfte, welche durch das Einschaltgerät auf den Schalthebel ausgeübt werden, kann es zu einer Beschädigung bzw. zu einem Bruch des Schalthebels kommen. Dadurch wird ein an sonst voll funktionsfähiges Schaltgerät für den Betrieb unbrauchbar.There are switching devices are known, which have shift lever for manually closing and / or opening of switch contacts. These shifters are exposed to a variety of loads during operation. In addition to manual operation of this lever must also withstand the loads of an automatic switch-on. Due to the forces exerted by the ballast on the shift lever, it may cause damage or breakage of the shift lever. This makes an otherwise fully functional switching device unusable for operation.
Griffstücke zur Anordnung auf einem Schalthebel eines Schaltgeräts sind etwa aus der
Die
Aus der
Erfindungsgemäß wird dies dadurch erreicht, dass der Betätigungsfortsatz nächst der Steuertrommel wenigstens einen ersten Bereich aufweist, und einen, an den ersten Bereich angrenzenden, zweiten Bereich, und wobei der zweite Bereich - in einem Übergangsbereich vom ersten Bereich zum zweiten Bereich - eine Schulter ausbildet, und dass in dem Übergangsbereich die wenigstens eine Rastschulter angeordnet ist.According to the invention this is achieved in that the actuating extension next to the control drum has at least a first region, and a second region adjacent to the first region, and wherein the second region forms a shoulder in a transition region from the first region to the second region. and that in the transition region, the at least one latching shoulder is arranged.
Dadurch kann der Betätigungsfortsatz an die Belastungen durch ein Einschaltgerät angepasst werden, und die Lebensdauer des Schalthebels, und damit des gesamten Schaltgeräts, verlängert werden. Dadurch kann bei Verwendung eines Gehäuses, welches zum Zusammenbau des Schaltgeräts über den Schalthebel geschoben werden muss, erreicht werden, dass der Betätigungsfortsatz des Schalthebels breiter und/oder größer ist als die Gehäusedurchbrechung und dadurch eine bessere Handhabung ermöglicht bzw. und eine längere Lebensdauer erreicht werden, sowie ein breiterer Angriffspunkt für ein Einschaltgerät bereitgestellt werden Dadurch ist eine sichere Befestigung des Grifftücks auf dem Betätigungsfortsatz möglich. Dadurch ist ein sicheres Verrasten des Griffstückes an dem Betätigungsfortsatz möglich, wobei em zerstörungsfreies Entfernen des Griffstückes von dem Betätigungsfortsatz im Wesentlichen verhindert werden kann. Dadurch ist eine sichere Befestigung des Griffstücks auf dem Betätigungsfortsatz möglich. Dadurch kann die Rastwirkung der Rastschulter durch den größeren Querschnitt des zweiten Bereichs noch verstärkt werden, wodurch ein besonders sicheres Verrasten des Griffstückes an dem Betätigungsfortsatz ermöglicht wird.Thereby, the actuating extension can be adapted to the loads by a Einschaltgerät, and the life of the shift lever, and thus the entire switching device can be extended. This can be achieved when using a housing which must be pushed to assemble the switching device via the shift lever, that the actuating extension of the shift lever is wider and / or larger than the housing aperture, thereby enabling better handling and and a longer life can be achieved , As well as a wider point of attack for a ballast be provided This allows a secure attachment of Grifftücks on the Betätigungsfortsatz possible. As a result, a secure locking of the handle on the actuating extension is possible, with em nondestructive removal of the handle of the actuating extension can be substantially prevented. As a result, a secure attachment of the handle on the actuating extension is possible. As a result, the locking action of the locking shoulder can be reinforced by the larger cross section of the second region, whereby a particularly secure locking of the handle is made possible on the actuating extension.
Gemäß einer weiteren Ausführungsform der Erfindung kann vorgesehen sein, dass das Griffstück untrennbar mit dem Betätigungsfortsatz verbunden ist. Dadurch kann ein nachträgliches Entfernen des Griffstücks verhindert werden. Insbesondere kann verhindert werden, dass das Griffstück durch die Kräfte, welche durch das Einschaltgerät auf den Schalthebel ausgeübt werden, vom Betätigungsfortsatz getrennt wird. Dadurch kann bei einem Schaltgerät mit einem Gehäuse, bei welchem ein Gehäuseteil mit einer Durchbrechung über den Bereich mit dem Schalthebel gesteckt werden muss, um das Schaltgerät zu verschließen, etwa die gängigen Ausführungen von Fehlerstromschutzschaltern, auch ein Öffnen des Schaltgeräts verhindert werden, da der Schalthebel größer ausgeführt werden kann als die Durchbrechung m dem Gehäuseteil, und ein Abheben des Gehäuseteils daher nicht mehr möglich ist.According to a further embodiment of the invention can be provided that the handle is inseparably connected to the actuating extension. As a result, a subsequent removal of the handle can be prevented. In particular, it can be prevented that the handle is separated from the actuating extension by the forces exerted by the ballast on the shift lever. This can be prevented in a switching device with a housing in which a housing part with an opening over the area with the shift lever to close the switching device, such as the common versions of residual current circuit breakers, an opening of the switching device can be prevented because of the shift lever can be made larger than the opening m the housing part, and lifting the housing part is therefore no longer possible.

Dadurch kann ein besonders griffiges und haltbares Griffstück gebildet werden, welches die dauerhafte und unlösbare Verbindung des Griffstücks mit dem Betätigungsfortsatz vorteilhaft unterstützt, da durch die unterschiedlichen Querschnitte eine Schulter auf dem Betätigungsfortsatz gebildet wird, an der sich das Griffstück abstützen kann. Gemäß einer weiteren Ausbildung der Erfindung, bei welcher der Betätigungsfortsatz im Wesentlichen symmetrisch zu einer, durch die Drehachse verlaufenden, in einer Ebene im Wesentlichen normal zur Drehachse liegenden, Symmetrieachse ausgebildet ist, kann vorgesehen sein, dass beidseitig der Symmetrieachse je wenigstens eine Rastschulter in dem Übergangsbereich vom ersten Bereich zum zweiten Bereich ausgebildet ist, und dass an dem Griffstück jeweils eine entsprechend gegengleiche Rastnase angeordnet ist. Dadurch wird in beiden vorgesehenen Bewegungsrichtungen des Schalthebels ein besonders sicherer und dauerhafter Halt des Griffstücks auf dem Betätigungsfortsatz erreicht, wodurch eine hohe Lebensdauer des Schalters auch unter starker Belastung erreicht werden kann, und ein zerstörungsfreies Entfernen des Griffstücks von dem Betätigungsfortsatz verhindert werden kann.In a development of the invention, it can be provided that the first area has a first cross-sectional area in a plane substantially normal to the axis of rotation, and the second area has a second cross-sectional area in the plane substantially normal to the axis of rotation, and that the first cross-sectional area is smaller than that second cross-sectional area. As a result, a particularly grippy and durable handle can be formed, which advantageously supports the permanent and permanent connection of the handle with the actuating extension, since a shoulder is formed on the actuating extension by the different cross sections, on which the handle can be supported. According to a further embodiment of the invention, in which the actuating extension is substantially symmetrical to a, extending through the axis of rotation, lying in a plane substantially normal to the axis of rotation, symmetry axis, can be provided that on both sides of the symmetry axis at least one locking shoulder in the Transition region is formed from the first region to the second region, and that on the handle in each case a corresponding counter-locking catch is arranged. Characterized a particularly secure and lasting grip of the handle is achieved on the actuating extension in both directions of movement of the lever, whereby a long life of the switch can be achieved even under heavy load, and a non-destructive removal of the handle can be prevented by the actuating extension.
Gemäß einer weiteren Ausführungsform der Erfindung kann vorgesehen sein, dass der Betätigungsfortsatz eine Durchgangsöffnung aufweist, welche im Wesentlichen parallel zur Drehachse verläuft. Dadurch ist eine einfache Kopplung bzw. Kupplung mehrerer nebeneinander angeordneter Schaltgeräte derart möglich, dass diese gleichzeitig betätigbar sind.According to a further embodiment of the invention, it may be provided that the actuating extension has a passage opening which runs essentially parallel to the axis of rotation. As a result, a simple coupling or coupling of a plurality of adjacently arranged switching devices is possible such that they are simultaneously actuated.
In diesem Zusammenhang kann in Weiterführung der Erfindung vorgesehen sein, dass die Durchgangsöffnung im zweiten Bereich des Betätigungsfortsatzes angeordnet ist. Dadurch ist der zur Verfügung stehende Hebelarm besonders lang, wodurch die zur Aufbringung des notwendigen Momentes nötige Kraft gering gehalten werden kann.In this context, it can be provided in a continuation of the invention that the passage opening is arranged in the second region of the actuating extension. As a result, the available lever arm is particularly long, whereby the necessary force for applying the necessary torque can be kept low.

Hiezu ist vorgesehen, dass der Betätigungsfortsatz 2 nächst der Steuertrommel 7 wenigstens einen ersten Bereich 9 mit einer ersten Querschnittsfläche in einer Ebene im Wesentlichen normal zur Drehachse 6 aufweist, und einen, an den ersten Bereich 9 angrenzenden, zweiten Bereich 10 mit einer zweiten Querschnittsfläche in der Ebene im Wesentlichen normal zur Drehachse 6 aufweist, und dass die erste Querschnittsfläche kleiner als die zweite Querschnittsfläche ist. Dadurch kann erreicht werden, dass das Griffstück 3 den Betätigungsfortsatz 2 umgreift und sich an der durch den größeren zweiten Bereich 10 gebildeten Schulter 15 mit der Rastnase 5 abstützen kann bzw. an dieser Schulter 15 verankert ist. Die erste und/oder zweite Querschnittsfläche kann insbesondere ohne gegebenenfalls im ersten Bereich 9 und/oder im zweiten Bereich 10 angeordnete Ausnehmungen bzw. Durchgangsöffnungen 11 ermittelt werden.The
Das Griffstück 3 weist, wie bei den dargestellten Ausführungsformen, einen Körper 14 auf, welcher in dessen, dem Benutzer zugänglichen äußeren Form unterschiedlich gestaltet sein kann, und dessen innere Formgebung der äußeren Form des Betätigungsfortsatzes 2 entspricht, sodass sich das Griffstück 3 in vorteilhafter Weise besonders innig an den Betätigungsfortsatz 2 anschmiegen kann.

Besonders bevorzugt ist vorgesehen, dass der Betätigungsfortsatz 2 im Wesentlichen symmetrisch zu einer, durch die Drehachse 6 verlaufenden, in einer Ebene im Wesentlichen normal zur Drehachse 6 liegenden, Symmetrieachse 18 ausgebildet ist, wobei vorgesehen ist, dass beidseitig der Symmetrieachse 18 je wenigstens eine Rastschulter 16 in dem Übergangsbereich 17 vom ersten Bereich 9 zum zweiten Bereich 10 ausgebildet ist, und dass an dem Griffstück 3 jeweils eine entsprechend gegengleiche Rastnase 5 angeordnet ist. Die Rastschultern 16 sind, wie in den
Zur einfachen Kopplung bzw. Kupplung mehrerer nebeneinander angeordneter Schaltgeräte, etwa mittels eines langen, dünnen Elements, etwa eines Drahtes, welche eine gleichzeitige Betätigung dieser gekoppelten Schaltgeräte ermöglicht, kann vorgesehen sein, dass der Betätigungsfortsatz 2 eine Durchgangsöffnung 11 zur Durchführung des langen dünnen Elements, insbesondere des Drahtes, ausweist, welche im Wesentlichen parallel zur Drehachse 6 verläuft. Durch Anordnung der Durchgangsöffnung 11 im zweiten Bereich 10 des Betätigungsfortsatzes 2 kann ein besonders langer Hebelarm erreicht werden, wodurch die zur Aufbringung des notwendigen Momentes nötige Kraft gering gehalten werden kann.For simple coupling or coupling of a plurality of juxtaposed switching devices, such as by means of a long, thin element, such as a wire, which is a simultaneous Actuation of these coupled switching devices allows, it can be provided that the actuating extension 2 a
