Die Erfindung betrifft eine mechanische und elektrische Verriegelungsvorrichtung eines motorisch betätigbaren Schaltgerätes, welches einen motorisch antreibbaren Schaltknebel, ein mit dem Schaltknebel zusammenwirkendes mechanisches Blockierelement sowie einen in den Versorgungsstromkreis des motorischen Antriebs eingesetzten elektrischen Verriegelungsschalter aufweist. Eine derartige Verriegelungsvorrichtung ist beispielsweise aus der DE 694 06 026 T2 bekannt.The invention relates to a mechanical and electrical locking device a motorized switchgear, which is a motor-driven shift knob, a mechanical blocking element interacting with the switching knob as well as one in the supply circuit of the motor Electric interlock switch used in the drive having. Such a locking device is known for example from DE 694 06 026 T2.

Die aus der DE 694 06 026 T2 bekannte Verriegelungsvorrichtung weist ein Sperrglied zur mechanischen und elektrischen Sicherung eines Motorantriebsblocks auf, welches im Wesentlichen einen im Gehäuse des Motorantriebsblocks versenkbaren Bügel umfasst. Der Bügel wirkt direkt mit einem Schaltknebel und indirekt mit einem Schalter im Versorgungsstromkreis des Motorantriebsblocks zusammen.The locking device known from DE 694 06 026 T2 has a locking member for mechanical and electrical Securing an engine drive block, which is essentially one retractable in the housing of the motor drive block Includes temple. The bracket works directly with a shift knob and indirectly with a switch in the supply circuit of the Engine drive blocks together.

Der Erfindung liegt die Aufgabe zugrunde, eine besonders einfach und Raum sparend aufgebaute mechanische und elektrische Verriegelungsvorrichtung für ein motorisch betätigbares Schaltgerät anzugeben.The invention is based, a particularly simple task and space-saving mechanical and electrical Locking device for a motor-operated Specify switching device.

Diese Aufgabe wird erfindungsgemäß gelöst durch eine Verriegelungsvorrichtung mit den Merkmalen des Anspruchs 1. Diese Verriegelungsvorrichtung dient sowohl der mechanischen als auch der elektrischen Verriegelung eines Schaltgerätes, welches einen motorisch antreibbaren Schaltknebel aufweist. Mit dem Schaltknebel wirkt mechanisch ein Blockierelement der Verriegelungsvorrichtung zusammen, welches zugleich der direkten Betätigung eines in den Versorgungsstromkreis des motorischen Antriebs eingesetzten elektrischen Verriegelungsschalters dient. Durch die direkte Betätigung des elektrischen Schalters mittels des mechanischen Blockierelementes ist sowohl ein konstruktiv einfacher als auch ein Raum sparender Aufbau der Verriegelungsvorrichtung gegeben.This object is achieved according to the invention by a locking device with the features of claim 1. This Locking device serves both mechanical and also the electrical locking of a switching device, which has a motor-driven shift knob. With the switching toggle acts mechanically a blocking element Locking device together, which is also the direct Actuation of one in the supply circuit of the motor Electric interlock switch used in the drive serves. By direct actuation of the electrical Switch by means of the mechanical blocking element is both a structurally simple and a space-saving Structure of the locking device given.

Vorzugsweise ist die Verriegelungsvorrichtung derart gestaltet, dass der elektrische Verriegelungsschalter dem mechanischen Blockierelement vorauseilend ist. Mit anderen Worten: Wird das Blockierelement betätigt, um den Schaltknebel mechanisch und elektrisch zu blockieren, so wird zwangsläufig vor dem mechanischen Blockieren des Schaltknebels der Versorgungsstromkreis des motorischen Antriebs durch Öffnen des Verriegelungsschalters elektrisch verriegelt. Durch das vorauseilende Schaltverhalten des elektrischen Verriegelungsschalters ist sichergestellt, dass bei mechanisch blockiertem Schaltknebel in keinem Fall dessen elektrischer Antrieb mit Energie versorgt werden kann.The locking device is preferably designed such that that the electrical interlock switch to the mechanical Blocking element is leading. In other words: If the blocking element is actuated, the switch toggle mechanically and electrically blocking, it is inevitable the mechanical blocking of the switching knob of the supply circuit the motor drive by opening the Locking switch electrically locked. By the leading Switching behavior of the electric interlock switch ensures that mechanically blocked Switch knob never with its electric drive Energy can be supplied.

Das Blockierelement weist vorzugsweise eine erste Öffnung auf, die eine Sicherung in blockierter Position des Schaltknebels mittels eines Schlosses, beispielsweise Vorhangschlosses, ermöglicht. Eine zweite Öffnung im Blockierelement ist vorzugsweise für einen Plombierdraht vorgesehen. Eine Einrastung des Blockierelementes in mindestens einer Raststellung kann durch eine entsprechende Rastvorrichtung ermöglicht sein.The blocking element preferably has a first opening on, a fuse in the locked position of the shift knob by means of a lock, for example a padlock, allows. A second opening in the blocking element is preferably provided for a sealing wire. A Locking the blocking element in at least one locking position can be made possible by an appropriate locking device his.

Das Blockierelement ist mittels einer manuellen Betätigungsvorrichtung und/oder einer werkzeugbetätigbaren Verstellvorrichtung betätigbar. Die manuelle Betätigungsvorrichtung kann bei Ausbildung des Blockierelementes als schwenkbarer Hebel beispielsweise in Form eines an den Hebel angeformten Griffstücks realisiert sein.The blocking element is by means of a manual actuation device and / or a tool-operated adjustment device actuated. The manual actuator can when the blocking element is designed as a pivotable lever for example in the form of a handle molded onto the lever be realized.

Nach einer besonders bevorzugten Ausführungsform der Verriegelungsvorrichtung ist das Blockierelement als drehbare Scheibe ausgebildet. Eine solche flache Scheibe ist besonders gut in ein Gerätegehäuse integrierbar und ragt unabhängig von der Schaltstellung nicht oder nicht wesentlich über die Gehäusekontur hinaus. Eine unbeabsichtigte Verstellung der Scheibe ist daher, selbst wenn diese nicht mittels eines Schlosses festgestellt ist, praktisch ausgeschlossen. Eine Rastfunktion der Scheibe ist vorzugsweise mittels eines mit dieser zusammenwirkenden oder an dieser angeformten Federelementes gegeben.According to a particularly preferred embodiment of the locking device is the blocking element as rotatable Disc formed. Such a flat disc is special easy to integrate into a device housing and projects independently of the switching position is not or not significantly over the housing contour out. An unintentional adjustment of the Disc is therefore, even if this is not by means of a Lock is determined, practically excluded. A Locking function of the disc is preferably by means of a this cooperating or molded on this spring element given.

Zur Anzeige des Schaltzustandes der Verriegelungsvorrichtung ist vorzugsweise ein Anzeigeelement in die Scheibe integriert. Ist eine Betätigung der Scheibe ausschließlich oder alternativ zur manuellen Betätigung mittels eines Werkzeugs vorgesehen, so bildet die Verstellvorrichtung zum Ansetzen des Werkzeugs bevorzugt zugleich das Anzeigeelement.To display the switching status of the locking device a display element is preferably integrated into the pane. Is an actuation of the disc exclusively or alternatively to manual operation using a tool provided, so the adjustment device for attachment of the tool also prefers the display element.

Die FIG 1 bis 4 zeigen ein Schaltgerät 1 mit einem in nicht näher dargestellter Weise motorisch antreibbaren Schaltknebel 2, welcher sich in den Darstellungen in Aus-Position befindet (FIG 1 und 3: Vorderansicht; FIG 2 und 4: Rückansicht). Lediglich in der in allen genannten FIG dargestellten Aus-Position ist der Schaltknebel 2 mittels eines als Hebel ausgebildeten Blockierelementes 3 blockierbar. Das schwenkbare Blockierelement 3 weist hierzu einen Vorsprung 4 auf, welcher einen Rücksprung 5 des Schaltknebels 2 hintergreifen kann. Ist das Blockierelement 3 aus dem Gehäuse 6 des Schaltgerätes 1 ausgeschwenkt (FIG 1 und 2), so ist eine erste Öffnung 7 für ein Vorhangschloss und eine zweite Öffnung 8 für einen Plombierdraht sichtbar.1 to 4 show a switching device 1 with an in not Shown in more detail, motor-driven switching knob 2, which is in the off position in the representations (FIG 1 and 3: front view; FIG 2 and 4: rear view). Only in the shown in all the FIG The switch toggle 2 is in the off position by means of a lever trained blocking element 3 can be blocked. The swiveling For this purpose, blocking element 3 has a projection 4, which engages behind a recess 5 of the shift knob 2 can. Is the blocking element 3 from the housing 6 of the switching device 1 swung out (FIG 1 and 2), so is a first opening 7 for a padlock and a second opening 8 for a sealing wire visible.

In den nicht dargestellten Versorgungsstromkreis für den motorischen Antrieb des Schaltknebels 2 ist ein als Mikroschalter ausgebildeter Verriegelungsschalter 9 eingesetzt. Der Verriegelungsschalter 9 ist direkt durch das Blockierelement 3 betätigbar, welches in FIG 5 genauer dargestellt ist. Das Blockierelement 3 weist im Wesentlichen eine L-förmige Außenkontur auf, wobei eine Oberkante 10 im eingeklappten Zustand des Blockierelementes 3, in welchem der Schaltknebel 2 freigegeben ist (FIG 3 und 4), bündig mit einer Gehäuseoberkante 11 des Schaltgerätes 1 abschließt. An die Oberkante 10 schließt sich, im eingeklappten Zustand des Blockierelementes 3 zu einer Gehäuseseitenkante 12 hin gerichtet, eine manuell betätigbare Betätigungsvorrichtung 13 in Form eines Griffstücks an. Das Blockierelement 3 ist somit von der Gehäuseseitenkante 12 aus zur manuellen Betätigung zugänglich. Das Griffstück 13 ist an einem Hebelarm 14 des Blockierelementes 3 angeformt, welcher zusätzlich zwei Rastvertiefungen 15 als Rastvorrichtungen aufweist, die mit einer am Gehäuse 6 angeformten Rastfeder 16 zusammenwirken. Somit ist das Blockierelement 3 sowohl in der den Schaltknebel 2 blockierenden Position (FIG 1 und 2) als auch in der den Schaltknebel 2 freigebenden Position (FIG 3 und 4) rastbar. In the supply circuit, not shown, for the motor The control knob 2 is driven as a microswitch trained locking switch 9 used. The Locking switch 9 is directly through the blocking element 3 operable, which is shown in more detail in FIG 5. The Blocking element 3 essentially has an L-shaped outer contour on, with an upper edge 10 in the folded state of the blocking element 3, in which the shift knob 2 is released is (FIG 3 and 4), flush with an upper edge of the housing 11 of the switching device 1 completes. To the top edge 10 closes when the blocking element is folded 3 directed towards a housing side edge 12, one manually actuatable actuator 13 in the form of a handle on. The blocking element 3 is thus from the housing side edge 12 off accessible for manual operation. The Handle 13 is on a lever arm 14 of the blocking element 3 integrally formed, which in addition two locking recesses 15 as Has latching devices, which are molded onto the housing 6 Interlocking spring 16 cooperate. Thus, the blocking element 3 both in the position blocking the switching knob 2 (FIG 1 and 2) as well as in the releasing the switching knob 2 Position (FIG 3 and 4) can be locked.

Ein Herausklappen des Blockierelementes 3 aus dem Gehäuse 6 ist ausschließlich möglich, wenn sich der Schaltknebel 2 in der dargestellten Aus-Position befindet. Beim Ausschwenken des Blockierelementes 3 öffnet zunächst der mit dem Hebelarm 14 zusammenwirkende Verriegelungsschalter 9, bevor das Blockierelement 3 den Schaltknebel 2 mechanisch blockiert. Durch dieses vorauseilende Schaltverhalten des elektrischen Verriegelungsschalters 9 ist es ausgeschlossen, dass eine motorische Betätigung des Schaltknebels 2 in Gang gesetzt wird, wenn dieser mechanisch verriegelt ist. Die Gefahr einer Beschädigung des Schaltgerätes 1 durch Einschalten des elektrischen Antriebs trotz mechanischer Blockierung ist somit nicht gegeben.Folding the blocking element 3 out of the housing 6 is only possible if the shift knob 2 in the shown off position. When swinging out the blocking element 3 first opens with the lever arm 14 cooperating locking switch 9 before the blocking element 3 the shift knob 2 mechanically blocked. By this leading switching behavior of the electric interlock switch 9 it is excluded that a motor Actuation of the control knob 2 is started, if it is mechanically locked. The risk of damage of the switching device 1 by switching on the electrical Actuator despite mechanical blocking is therefore not given.

Die FIG 6 zeigt perspektivisch das Schaltgerät 1, welches zum Aufsetzen auf eine Tragschiene vorgesehen ist. Auf den Schaltknebel 2 ist eine Verbindungsschiene 17 aufgeschoben, mittels welcher das als Fernbedienungseinheit dienende Schaltgerät 1 mit einem ebenfalls auf die Tragschiene aufsetzbaren, im Allgemeinen konturengleichen Reiheneinbaugerät verbindbar ist.6 shows in perspective the switching device 1, which for It is intended to be placed on a mounting rail. On the Switch toggle 2, a connecting rail 17 is pushed on, by means of which serves as a remote control unit Switchgear 1 with a switch that can also be placed on the mounting rail, generally contour-matched modular device is connectable.

Die FIG 7 bis 10 zeigen ein Schaltgerät 1 in einer bevorzugten alternativen Ausführungsform. Ein in FIG 11 a und b genauer dargestelltes Blockierelement 3 ist in diesem Fall als drehbare Scheibe ausgebildet, welche parallel zur Gehäuseoberkante 11 nahezu vollständig innerhalb des Gehäuses 6 angeordnet ist. Analog zum Ausführungsbeispiel nach den FIG 1 bis 6 ist eine Betätigungsvorrichtung 13, hier in Form eines geriffelten Randes der Scheibe 3, der Gehäuseseitenkante 12 zugewandt. Aufgrund der Ausbildung des Blockierelementes 3 als Scheibe ist dieses jedoch unabhängig von der Schaltstellung stets praktisch vollständig in die Konturen des Schaltgerätes 1 integriert. Eine unbeabsichtigte Betätigung, wie sie beispielsweise durch Berührung eines Hebels leicht möglich wäre, muss daher im Fall des scheibenförmigen Blockierelementes 3 nicht in Erwägung gezogen werden. 7 to 10 show a switching device 1 in a preferred alternative embodiment. A more precisely in FIG 11 a and b shown blocking element 3 is in this case as rotatable disc, which is parallel to the upper edge of the housing 11 arranged almost completely within the housing 6 is. Analogous to the exemplary embodiment according to FIG. 1 to 6 is an actuator 13, here in the form of a corrugated edge of the disc 3, the housing side edge 12 facing. Due to the design of the blocking element 3 as a disc, however, this is independent of the switch position always practically completely in the contours of the switchgear 1 integrated. Accidental activity, such as it is easily possible, for example, by touching a lever would have to be in the case of the disk-shaped blocking element 3 should not be considered.

Das scheibenförmige Blockierelement 3 weist an dessen Umfang einen Vorsprung 4 auf, welcher ähnlich wie im Ausführungsbeispiel nach den FIG 1 bis 6 der Verriegelung des Schaltknebels 2 dient. Umfangsseitig des scheibenförmigen Blockierelementes 3 ist weiter ein bogenförmiges Federelement 18 als Rastvorrichtung angeformt. Die elastische Rastvorrichtung 18 wirkt in nicht näher dargestellter Weise mit einer starren Struktur innerhalb des Gehäuses 6 zusammen. Auf der der Gehäuseoberkante 12 abgewandten Seite des Blockierelementes 3 ist, wie in FIG 11b sichtbar, eine Schaltkontur 19 angeordnet, welche der direkten Betätigung des elektrischen Verriegelungsschalters 9 dient. Wie ferner aus FIG 11b ersichtlich ist, erstreckt sich die Schaltkontur 19 über einen weiteren Winkelbereich als der Vorsprung 4, womit ein vorauseilendes Schaltverhalten des elektrischen Verriegelungsschalters 9 in Relation zur mechanischen Blockierfunktion des Blockierelementes 3 gegeben ist.The disk-shaped blocking element 3 has on its circumference a projection 4, which is similar to the embodiment 1 to 6 of the locking of the shift knob 2 serves. Circumferential side of the disk-shaped blocking element 3 is also an arcuate spring element 18 as a locking device formed. The elastic locking device 18 acts in a manner not shown with a rigid structure inside the housing 6 together. On the top of the case 12 facing away from the blocking element 3 is how visible in FIG 11b, a switching contour 19 which the direct actuation of the electric interlock switch 9 serves. As can also be seen from FIG. 11b, extends the switching contour 19 over a further angular range than the protrusion 4, with a leading switching behavior of the electric locking switch 9 in relation for the mechanical blocking function of the blocking element 3 is given.

Die FIG 7 bis 9 zeigen das Schaltgerät 1 in drei unterschiedlichen Schaltzuständen. Eine Verstellvorrichtung 20 mit einem Schlitz 21 ist mittig auf dem Blockierelement 3 angeordnet und durch eine Betätigungsöffnung 22 im Gehäuse 6 zugänglich. Die Verstellvorrichtung 20 ist so weit aus dem im Wesentlichen ebenen Blockierelement 3 hervorgehoben, dass deren Oberfläche etwa bündig zur Oberfläche des Gehäuses 6 angeordnet ist. Der Schlitz 21 dient sowohl der Betätigung mittels eines Schraubenziehers als auch der Anzeige des Schaltzustandes des Blockierelementes 3.Figures 7 to 9 show the switching device 1 in three different Switching states. An adjustment device 20 with a Slot 21 is arranged centrally on the blocking element 3 and accessible through an actuating opening 22 in the housing 6. The adjustment device 20 is essentially as far from that flat blocking element 3 highlighted that its surface arranged approximately flush with the surface of the housing 6 is. The slot 21 serves both for actuation by means of a Screwdriver and the display of the switching state of the Blocking element 3.

Im Schaltzustand nach FIG 7 ist das Schaltgerät 1 sowohl elektrisch als auch manuell schaltbar. Wird das Blockierelement 3 etwa um 45° nach links gedreht, so ist das Schaltgerät 1 weiterhin manuell schaltbar, d.h. der Vorsprung 4 befindet sich noch nicht im Eingriff mit dem Schaltknebel 2, jedoch elektrisch abgeschaltet, d.h. der Verriegelungsschalter 9 ist durch das Blockierelement 3 betätigt (FIG 8). Bei weiterer Drehung des Blockierelementes 3 um 45° tritt auch die mechanische Blockierung des Schaltknebels 2 in Funktion. In diesem Schaltzustand (FIG 9) sind durch eine Gehäuseaussparung 23 hindurch auch die Öffnungen 7,8 für ein Vorhangschloss bzw. einen Plombierdraht zugänglich. Das Federelement 18 bewirkt eine Einrastung des Blockierelementes 3 in jedem der in den FIG 7 bis 9 dargestellten Schaltzustände.In the switching state according to FIG 7, the switching device 1 is both electrical as well as manually switchable. Will the blocking element 3 rotated about 45 ° to the left is the switchgear 1 still switchable manually, i.e. the projection 4 is located not yet engaged with the shift knob 2, however electrically switched off, i.e. the lock switch 9 actuated by the blocking element 3 (FIG 8). With another Rotation of the blocking element 3 by 45 ° also occurs the mechanical Blocking of the toggle 2 in operation. In this Switching state (FIG 9) are through a housing recess 23 the openings 7, 8 for a padlock or a sealing wire accessible. The spring element 18 causes a locking of the blocking element 3 in each of the 7 to 9 shown switching states.
