Abstract
Description
Die Erfindung betrifft einen abschließbaren handbetätigten Drehantrieb für elektrische Schaltgeräte, beispielsweise für Motorschutzschalter oder kleinere Leistungsschalter.The invention relates to a lockable manually operated rotary drive for electrical switching devices, such as motor protection switch or smaller circuit breaker.
Derartige Drehantriebe sind aus den Druckschriften
So weist das mit der Abschließöffnung versehene schwenkbare Sperrglied des Drehantriebes nach
Der Drehantrieb nach
Von Nachteil ist, dass derartige Drehantriebe nur begrenzt von außen einwirkenden Kräften standhalten. Die Abschließstellung kann gewaltsam überwunden und das Schaltgerät entgegen den Sicherheitsanforderungen von der Aus- in die Ein-Stellung überführt werden kann. Damit werden Personal und Anlagen erheblichen Gefahren ausgesetzt. Die Verwendung von Stahlteilen zur Erhöhung der Überwindungskraft, wie z.B. bei Zylindersicherheitsschlössern oder Stellantrieben in Chemieanlagen üblich, ist bei dem eingangs genannten Drehantrieb mit der Inkaufnahme erheblicher Nachteile, insbesondere erhöhten Herstellungskosten und Aufwendungen für die elektrische Erdung, verbunden.The disadvantage is that such rotary actuators withstand only limited external forces. The closed position can be violently overcome and the switching device can be transferred against the safety requirements of the off in the on position can. This exposes personnel and equipment to significant hazards. The use of steel parts to increase the overcoming force, such as usual in cylinder security locks or actuators in chemical plants, in the rotary drive mentioned above with the purchase of considerable disadvantages, in particular increased production costs and expenses for electrical grounding connected.
Der Erfindung liegt daher die Aufgabe zugrunde, den eingangs genannten Drehantrieb mit einfachen Mitteln weitgehend vor der gewaltsamen Überwindung der abgeschlossenen Stellung zu schützen.The invention is therefore based on the object to protect the aforementioned rotary drive with simple means largely before the violent overcoming of the closed position.
Ausgehend von einem Drehantrieb der eingangs genannten Art wird die Aufgabe erfindungsgemäß durch die Merkmale des unabhängigen Anspruches gelöst, während den abhängigen Ansprüchen vorteilhafte Weiterbildungen der Erfindung zu entnehmen sind.Starting from a rotary drive of the type mentioned, the object is achieved by the features of the independent claim, while the dependent claims advantageous developments of the invention are apparent.
Eine die bekannten Drehantriebe ergänzende und weitgehend über den Drehgriff stülpbare Schutzkappe ist an die Form des Drehgriffes angepasst und gestattet den Zutritts zu der mindestens einen Abschließöffnung, um das Einhängen des Bügels eines Bügelschlosses zum Abschließen des Drehantriebes im ausgeschalteten Zustand des Schaltgerätes zu ermöglichen. Die übergestülpte Schutzkappe ist in Verbindung mit dem eingehängten Bügel auf dem Gehäuse über eine formschlüssige Verbindung fixiert.A well-known rotary actuators complementary and largely slipped over the rotary handle cap is adapted to the shape of the rotary handle and allows access to the at least one Abschließöffnung to allow the hanging of the bracket of a U-lock for completing the rotary drive in the off state of the switching device. The turned-over protective cap is fixed in conjunction with the hinged bracket on the housing via a positive connection.
Durch die weitgehende Abdeckung des Drehgriffes durch die Schutzkappe einerseits und die Fixierung der Schutzkappe anderseits wird ein abschließbarer Drehantrieb geschaffen, der im Vergleich zu einem ungeschützten Drehantrieb sowohl eine erheblich geringere Angriffsfläche für als auch einen erheblich größeren Widerstand gegen von außen angreifende Kräfte bietet, mit denen versucht wird, den abgeschlossenen Drehgriff gewaltsam aus der Aus-Stellung in die Ein-Stellung zu überführen. Mit dem erfindungsgemäßen Drehantrieb wird die Sicherheit hinsichtlich der Überwindung des abgeschlossenen Zustandes und damit gegen gefährliche Folgen vandalistischer Eingriffe beträchtlich erhöht, wobei - ausgehend von einem üblichen abschließbaren Drehantrieb nach dem Stand der Technik - lediglich einfach zu realisierende Maßnahmen ohne großen Kostenaufwand durchzuführen sind.Due to the extensive coverage of the rotary handle by the protective cap on the one hand and the fixation of the cap on the other hand, a lockable rotary drive is created, which offers both a significantly lower attack surface and a much greater resistance to externally applied forces compared to an unprotected rotary drive with which an attempt is made to forcibly transfer the completed twist grip from the off position to the on position. With the rotary drive according to the invention, the safety in terms of overcoming the closed state and thus against dangerous consequences of vandalistic interventions is considerably increased, - are to be carried out from a conventional lockable rotary drive according to the prior art - only easy to implement measures without much cost.
Das Gehäuse, mit dem die Schutzkappe die formschlüssige Verbindung eingeht, ist in vorteilhafter Ausgestaltung der Erfindung dasjenige Gehäuse, das baulich mit dem Drehgriff vereinigt ist, oder - falls diese bauliche Vereinigung nicht besteht - das entweder mit dem über den Drehantrieb zu betätigenden Schaltgerät baulich vereinigt ist oder das als separates Gehäuse, beispielsweise als Installationsgehäuse oder als Schaltschrank, an dessen Tür der Drehantrieb in Form eines Türkupplungsdrehgriffes montiert ist, das Schaltgerät umgibt.The housing with which the protective cap enters into the positive connection, in an advantageous embodiment of the invention, that housing which is structurally associated with the rotary handle, or - if this structural association does not exist - which structurally combined either with the switching device to be actuated via the rotary drive or is as a separate housing, for example as an installation housing or as a control cabinet, mounted on the door of the rotary drive in the form of a door coupling rotary handle, the switching device surrounds.
In vorteilhafter Weiterbildung der Erfindung steht von der Schutzkappe an ihrer zum Schaltgerät weisenden Rückseite mindestens eine Anformung ab, die im übergestülpten Zustand der Schutzkappe jeweils in eine entsprechend ausgebildete frontseitige Ausformung im Gehäuse greift, wodurch die Schutzkappe radial zum Verlauf der Betätigungsachse festgelegt ist. Die Fixierung der Schutzkappe in axialer Richtung bewirkt das mindestens eine Bügelschloss im Zusammenwirken mit der weitgehend den Drehgriff überdeckenden Form der Schutzkappe.In an advantageous embodiment of the invention is at least one Anformung from the protective cap on its rear facing the switching device, which engages in the over-slipped state of the cap each in a correspondingly shaped front molding in the housing, whereby the protective cap is fixed radially to the course of the actuating axis. The fixation of the protective cap in the axial direction causes the at least one U-lock in cooperation with the largely covering the rotary handle form of the protective cap.
Eine hierzu alternative Weiterbildung besteht darin, dass die Schutzkappe mit mindestens einer ihrer Seitenwände formschlüssig um mindestens eine Seitenwand des Gehäuses greift.An alternative development for this purpose is that the protective cap engages with at least one of its side walls positively around at least one side wall of the housing.
Eine weitere hierzu vorteilhafte Weiterbildung besteht darin, dass die Schutzkappe mit der rückseitigen Stirnfläche mindestens einer ihrer Seitenwände formschlüssig in mindestens eine an der Frontseite des Gehäuses ausgesparte Nut greift.Another advantageous further development is that the protective cap with the rear end face of at least one of its side walls engages positively in at least one recessed on the front side of the housing groove.
Eine zweckmäßige Ausbildung besteht darin, dass die Schutzkappe ein Spritzgussteil aus Kunststoff oder Metall ist. Eine Schutzkappe aus Kunststoff ist einfach und billig herzustellen. Eine Schutzkappe aus Metall bietet einen noch höheren Widerstand gegen angreifende Kräfte, wobei keine zusätzlichen Erdungsmaßnahmen erforderlich sind.An expedient embodiment is that the protective cap is an injection molded part made of plastic or metal. A protective plastic cap is easy and cheap to manufacture. A protective metal cap provides even greater resistance to attacking forces, with no additional grounding required.
