Description

Die Erfindung betrifft eine Anordnung zur Blockierung eines Betätigungselements, welches zum Ein- und Ausschalten eines Elektroinstallationsgeräts vorgesehen ist, sowie ein Elektroinstallationsgerät mit einer derartigen Blockier-Anordnung.The invention relates to an arrangement for blocking an actuating element, which is provided for switching on and off of an electrical installation device, as well as an electrical installation device with such a blocking arrangement.

Elektroinstallationsgeräte, beispielsweise Leistungsschalter oder Leitungsschutzschalter, werden zur Absicherung von Netzen eingesetzt. Dabei ist es in manchen Fällen erforderlich, ein unbeabsichtigtes oder unbefugtes Einschalten des Elektroinstallationsgeräts zu verhindern, beispielsweise wenn an dem abgesicherten Netz gearbeitet wird, um eine Gefährdung der Gesundheit oder des Lebens der mit den Arbeiten betrauten Personen unter allen Umständen auszuschließen. In anderen Fällen muss verhindert werden, dass das Elektroinstallationsgerät unbeabsichtigt ausgeschaltet und damit das Netz abgeschaltet wird.Electrical installation equipment, such as circuit breakers or circuit breakers, are used to secure networks. In some cases, it is necessary to prevent inadvertent or unauthorized switching on of the electrical installation device, for example when working on the secure network, in order to exclude any risk to the health or life of the person entrusted with the work in all circumstances. In other cases, it must be prevented that the electrical installation device unintentionally switched off and thus the power is turned off.

Bei Elektroinstallationsgeräten, insbesondere bei Leistungsschaltern oder Leitungsschutzschaltern, erfolgt dieser Schutz gegen unbefugtes Betätigen des Bedienelements mit Hilfe einer Absperrvorrichtung, einer sogenannten Griffsperre. Diese weist einen Bügel auf, an dem ein Vorhängeschloss anbringbar ist, wodurch das unbeabsichtigte Ein- oder Ausschalten verhindert wird. Dabei besitzt der Bügel zwei Schenkel, deren freie Enden nach außen hin abgewinkelt sind. Diese freien Enden werden in Aufnahmelöcher am Elektroinstallationsgerät eingesteckt, wodurch das Betätigungselement des Elektroinstallationsgeräts in seiner Bewegung behindert wird.In electrical installation equipment, especially circuit breakers or circuit breakers, this protection against unauthorized operation of the control element by means of a shut-off, a so-called grip lock. This has a bracket on which a padlock is attached, whereby the unintentional switching on or off is prevented. In this case, the bracket has two legs whose free ends are angled outwards. These free ends are plugged into receiving holes on the electrical installation device, whereby the actuating element of the electrical installation device is hindered in its movement.

Hierbei besteht die Problematik, dass für unterschiedliche Bauformen an Elektroinstallationsgeräten unterschiedliche Absperrvorrichtungen vorgesehen werden müssen. Dies führt seitens des Herstellers zu einer höheren Teilevielfalt mit entsprechend höheren Kosten für Entwicklung, Lagerhaltung oder Logistik. Ferner muss auch ein Elektromonteur eine entsprechende Bevorratung vorhalten, was zu einem höheren Montageaufwand führt.Here, the problem is that different shut-off devices must be provided for different types of electrical installation equipment. This leads from the manufacturer to a higher variety of parts with correspondingly higher costs for development, warehousing or Logistics. Furthermore, an electrician must also provide a corresponding storage, which leads to a higher installation cost.

Es ist daher die Aufgabe der vorliegenden Erfindung, eine alternative Anordnung zur Blockierung eines Betätigungselements eines Elektroinstallationsgeräts sowie ein Elektroinstallationsgerät mit einer derartigen Anordnung bereitzustellen, welche sich durch geringere Kosten sowie einen deutlich reduzierten Montageaufwand auszeichnen.It is therefore the object of the present invention to provide an alternative arrangement for blocking an actuating element of an electrical installation device and an electrical installation device with such an arrangement, which are characterized by lower costs and a significantly reduced installation costs.

Diese Aufgabe wird durch die erfindungsgemäße Anordnung sowie das erfindungsgemäße Elektroinstallationsgerät gemäß den unabhängigen Ansprüchen gelöst. Vorteilhafte Ausgestaltungen sind Gegenstand der abhängigen Ansprüche.This object is achieved by the arrangement according to the invention and the electrical installation device according to the invention according to the independent claims. Advantageous embodiments are the subject of the dependent claims.

Die Erfindung betrifft eine Anordnung zur Blockierung eines Betätigungselements, welches zum Ein- und Ausschalten eines Elektroinstallationsgeräts vorgesehen ist. Dabei weist das Elektroinstallationsgerät zwei Rastöffnungen für ein Bügelelement auf, in die das Bügelelement einsteckbar ist, um eine Betätigung des Betätigungselements zu blockieren. Das Bügelelement weist hierzu zwei freie Enden für die beiden Rastöffnungen auf, wobei die beiden Rastöffnungen einen definierten Abstand zueinander aufweisen. Weiterhin weist die Anordnung ein Verschlusselement auf, welches mit dem Bügelelement gekoppelt ist, so dass bei einem Verschieben des Verschlusselements relativ zum Bügelelement die beiden freien Enden des Bügelelements in den Rastöffnungen fixiert werden, um das Betätigungselement zu blockieren. Ferner weist das Verschlusselement unterschiedliche Führungskonturen für das Bügelelement auf, welche für unterschiedliche Abstände der Rastöffnungen vorgesehen sind.The invention relates to an arrangement for blocking an actuating element, which is provided for switching on and off of an electrical installation device. In this case, the electrical installation device has two latching openings for a stirrup element, in which the stirrup element can be inserted in order to block an actuation of the actuating element. For this purpose, the stirrup element has two free ends for the two detent openings, wherein the two detent openings have a defined distance from each other. Furthermore, the arrangement has a closure element which is coupled to the bracket element, so that when the closure element is displaced relative to the bracket element, the two free ends of the bracket element are fixed in the latch openings in order to block the actuating element. Furthermore, the closure element has different guide contours for the stirrup element, which are provided for different distances of the detent openings.

Elektroinstallationsgeräte können sich hinsichtlich ihrer Gehäusebauform unterscheiden. Insbesondere werden bei der Elektroinstallation Geräte mit unterschiedlich breiten Gehäusebauformen verwendet. Da auch die Rastöffnungen, welche zum Einstecken des Bügelelements zur Blockierung der Bedienelements vorgesehen sind, am Gehäuse des Elektroinstallationsgeräts ausgebildet sind, weisen unterschiedlich breite Gehäusebauformen in der Regel unterschiedliche Abstände der Rastöffnungen auf. Mit Hilfe der erfindungsgemäßen Anordnung ist es nun möglich, unterschiedliche Elektroinstallationsgeräte mit verschieden Gehäusebauformen, d.h. mit Gehäusen unterschiedlicher Breite, ein unbefugtes Betätigen des Betätigungselements, d.h. ein unbeabsichtigtes ein- oder Ausschalten, zu verhindern. Die hierzu vorgesehene Absperrvorrichtung oder Griffsperre, bestehend aus dem Bügelelement und dem Verschlusselement, ist dabei an die unterschiedlichen Abstände der Rastöffnungen anpassbar. Die freien Enden des Bügelelements werden zum Blockieren des Betätigungselements in die Rastöffnungen des Elektroinstallationsgeräts gesteckt und mit Hilfe des Verschlusselements in dieser Position fixiert, wobei je nach Abstand der Rastöffnungen unterschiedliche Führungskonturen verwendet werden. Dabei sind keine unterschiedlichen Bauformen des Bügelelements bzw. des Verschlusselements erforderlich, es können auch für unterschiedliche Gehäusebauformen stets dieselben Bügelelemente und Verschlusselemente verwendet werden. Damit wird eine hohe Anzahl an Varianten für die Absperrvorrichtung vermieden, wodurch die Kosten für Entwicklung, Lagerhaltung oder Logistik deutlich reduziert werden können.Electrical installation devices may differ in terms of their housing design. In particular, in the electrical installation devices with different widths housing types used. Since the latching openings, which are provided for insertion of the bracket element for blocking the operating element, are formed on the housing of the electrical installation device, have different widths housing designs usually different distances of the latching openings. With the aid of the arrangement according to the invention, it is now possible to prevent different electrical installation devices with different housing designs, ie with housings of different widths, an unauthorized actuation of the actuating element, ie unintentional switching on or off. The provided for this purpose shut-off device or handle lock, consisting of the bracket element and the closure element, is adaptable to the different distances of the locking openings. The free ends of the stirrup element are inserted for blocking the actuating element in the latching openings of the electrical installation device and fixed by means of the closure element in this position, depending on the spacing of the detent openings different guide contours are used. In this case, no different designs of the bracket element or the closure element are required, it can also be used for different housing designs always the same bracket elements and closure elements. This avoids a large number of variants for the shut-off device, as a result of which the costs for development, warehousing or logistics can be significantly reduced.

Ferner wird durch die erfindungsgemäße Anordnung auch der Montageaufwand deutlich reduziert: Zum einen muss ein Elektroinstallateur keine Vielzahl an unterschiedlichen Absperrvorrichtungen vorhalten. Zum anderen besteht die Absperrvorrichtung lediglich aus zwei Teilen, dem Bügelelement und dem Verschlusselement, welche bei der Montage von Hand zusammengesteckt werden. Dabei ist kein Werkzeug erforderlich, so dass die Montage auf möglichst einfache Weise durchgeführt werden kann.Furthermore, the installation effort is also significantly reduced by the arrangement according to the invention: Firstly, an electrician does not have to hold a large number of different shut-off devices. On the other hand, the shut-off device consists only of two parts, the bracket element and the closure element, which are assembled together during assembly by hand. No tool is required, so that the assembly can be carried out in the simplest possible way.

In einer vorteilhaften Weiterbildung ist das Bügelelement als federelastisches Bügelelement ausgebildet, so dass die Anpassung an die vorbestimmten Abstände der Rastöffnungen unter Ausnutzung der Elastizität des Bügelelements erfolgt.In an advantageous development, the stirrup element is designed as a resilient stirrup element, so that adaptation to the predetermined distances of the detent openings takes place by utilizing the elasticity of the stirrup element.

Beim Anbringen der Absperrvorrichtung am Elektroinstallationsgerät wird das Bügelelement aufgrund seiner Eigenelastizität in die Rastöffnungen gedrückt und durch Aufschieben des Verschlusselements in dieser Position fixiert. Die Verwendung eines federelastischen Werkstoffs für das Bügelelement hat dabei den Vorteil, dass das Bügelelement elastisch verformbar ist, d.h. nach Entfernen des Bügelelements aus den Rastöffnungen nimmt dieses wieder seine ursprüngliche Form ein, es bleibt keine plastische Verformung am Bügelelement zurück. Somit ist die Absperrvorrichtung auch nach einem Entfernen vom Elektroinstallationsgerät wieder verwendbar. Das Bügelelement kann dabei sowohl aus Stahl, beispielsweise Federstahl, als auch aus einem elastisch verformbaren Kunststoff hergestellt sein.When attaching the shut-off device on the electrical installation device, the bracket member is pressed due to its inherent elasticity in the latching openings and fixed by sliding the closure element in this position. The use of a resilient material for the stirrup element has the advantage that the stirrup element is elastically deformable, i. after removal of the stirrup element from the detent openings this takes back its original shape, there is no plastic deformation on the bracket element back. Thus, the shut-off device is reusable even after removal from the electrical installation device. The bracket element can be made both of steel, such as spring steel, as well as of an elastically deformable plastic.

In einer weiteren, vorteilhaften Weiterbildung ist das Betätigungselement relativ zum Elektroinstallationsgerät zwischen einer ersten Position und einer zweiten Position bewegbar, wobei das Betätigungselement sowohl in der ersten Position als auch in der zweiten Position blockierbar ist.In a further advantageous development, the actuating element is movable relative to the electrical installation device between a first position and a second position, wherein the actuating element can be blocked both in the first position and in the second position.

Die erste Position und die zweite Position stellen die beiden Endpositionen des Betätigungselements dar, zwischen denen das Betätigungselement verstellbar ist, wobei eine der Endpositionen eine "EIN"-Stellung und die andere der Endpositionen eine "AUS"-Stellung markiert. In beiden Stellungen des Betätigungselements ist es möglich, die freien Enden des Bügelelements in die Rastöffnungen zu stecken und somit die Absperrvorrichtung an dem Elektroinstallationsgerät anzubringen. Auf diese Weise kann das Elektroinstallationsgerät sowohl in einem eingeschalteten Zustand, bei dem sich das Betätigungselement in der "EIN"-Stellung befindet, als auch im ausgeschalteten Zustand, bei dem sich das Betätigungselement in der "AUS"-Stellung befindet, mit Hilfe der Absperrvorrichtung vor unbefugter oder unbeabsichtigter Betätigung geschützt werden.The first position and the second position represent the two end positions of the actuating element between which the actuating element is adjustable, one of the end positions marking an "ON" position and the other of the end positions marking an "OFF" position. In both positions of the actuating element, it is possible to insert the free ends of the bracket element in the latching openings and thus to attach the shut-off device to the electrical installation device. In this way, the electrical installation device can both in an on state, in which the actuator is in the "on" position, as well as in the off State in which the actuator is in the "OFF" position, are protected by the shut-off device against unauthorized or accidental operation.

In einer weiteren, vorteilhaften Weiterbildung weist das Verschlusselement zumindest einen Rasthaken auf, mit dessen Hilfe ein Lösen des Bügelelements vom Verschlusselement unterbunden wird.In a further advantageous development, the closure element has at least one latching hook, by means of which a release of the strap element from the closure element is prevented.

Bei der Montage ist es erforderlich, das Bügelelement und das Verschlusselement zur Absperrvorrichtung zusammenzustecken, bevor diese am Elektroinstallationsgerät befestigt wird. Um zu vermeiden, dass sich das Bügelelement während der Montage wieder vom Verschlusselement löst, sind am Verschlusselement Rasthaken angeordnet. Diese können beim Zusammenstecken der Absperrvorrichtung, d.h. beim Zusammenfügen des Bügelelements und des Verschlusselements, unter Aufbringung einer geringen, zusätzlichen Fügekraft überwunden werden, verhindern aber ein anschließendes Lösen des Bügelelements vom Verschlusselement. Auf diese Weise kann die Absperrvorrichtung auf einfache und sichere Weise montiert werden.During assembly, it is necessary to assemble the yoke element and the closure element to the shut-off device before it is attached to the electrical installation device. In order to avoid that the bracket element dissolves again during assembly from the closure element, latching hooks are arranged on the closure element. These can be used when plugging the shut-off device, i. upon assembly of the stirrup element and the closure element, are overcome by applying a small, additional joining force, but prevent subsequent release of the stirrup element from the closure element. In this way, the shut-off device can be mounted in a simple and secure manner.

In einer weiteren, vorteilhaften Weiterbildung ist das Verschlusselement als Spritzgussbauteil herstellbar.In a further advantageous development, the closure element can be produced as an injection-molded component.

Das Spritzgussverfahren stellt eine einfache und kostengünstige Möglichkeit zur Herstellung des Verschlusselements dar. Aufgrund der vergleichsweise einfachen Form des Verschlusselements kann dieses als Spritzgussbauteil ausgeformt werden, wobei ein einfaches Spritzguss-Werkzeug ohne Seitenschieber zur Herstellung des Verschlusselements verwendet werden kann.The injection molding process represents a simple and cost-effective way of producing the closure element. Due to the comparatively simple shape of the closure element, it can be formed as an injection-molded component, whereby a simple injection-molding tool without a side slide can be used to produce the closure element.

Das erfindungsgemäße Elektroinstallationsgerät, welches insbesondere als Leistungsschalter oder Leitungsschutzschalter ausgebildet ist, weist eine Anordnung zur Blockierung eines Betätigungselements des Elektroinstallationsgeräts nach einem der vorhergehenden Ansprüche auf.The electrical installation device according to the invention, which is designed in particular as a circuit breaker or circuit breaker, has an arrangement for blocking an actuating element of the electrical installation device according to one of the preceding claims.

Hinsichtlich der Vorteile des Elektroinstallationsgeräts mit einer derartigen Anordnung zur Blockierung des Betätigungselements wird auf die Ausführungen zu den Vorteilen der Anordnung verwiesen.With regard to the advantages of the electrical installation device with such an arrangement for blocking the actuator is made to the comments on the advantages of the arrangement.

In den verschiedenen Figuren der Zeichnung sind gleiche Teile stets mit dem gleichen Bezugszeichen versehen. Die Beschreibung gilt für alle Zeichnungsfiguren, in denen das entsprechende Teil ebenfalls zu erkennen ist.In the various figures of the drawing, like parts are always provided with the same reference numerals. The description applies to all drawing figures in which the corresponding part can also be recognized.

Figur 1 zeigt ein drahtförmiges Bügelelement 5 in einer perspektivischen Darstellung. Es stellt den ersten Teil einer Anordnung zur Blockierung eines Betätigungselements 2 eines Elektroinstallationsgeräts 1 dar und besteht aus einem federelastischen Werkstoff, vorzugsweise aus Federstahl. Das Bügelelement 5 weist zwei nach außen abstehende, freie Enden 7 auf, welche über einen Steg 6 miteinander verbunden und in Rastöffnungen 4 des Elektroinstallationsgeräts 1 (siehe Fig. 4a/4b bzw. 5a/5b) einsteckbar sind. Durch das Einstecken der Enden 7 in die Rastöffnungen 4, welche zueinander einen definierten Abstand A aufweisen, wird eine Betätigung eines Betätigungsgriffs 2 (siehe Fig. 4a/4b) des Elektroinstallationsgeräts 1 sicher blockiert. FIG. 1 shows a wire-shaped bracket member 5 in a perspective view. It represents the first part of an arrangement for blocking an actuating element 2 of an electrical installation device 1 and consists of a resilient material, preferably made of spring steel. The bracket member 5 has two outwardly projecting, free ends 7, which are interconnected via a web 6 and in latching openings 4 of the electrical installation device 1 (see Fig. 4a / 4b or 5a / 5b) can be inserted. By inserting the ends 7 in the latching openings 4, which have a defined distance A to each other, an actuation of an actuating handle 2 (see Fig. 4a / 4b ) of the electrical installation device 1 safely blocked.

Figur 2 zeigt ein Verschlusselement 8 in einer perspektivischen Draufsicht. Das Verschlusselement 8 steht in montiertem Zustand (siehe Fig. 3a/3b) mit dem Bügelelement 5 in Wirkverbindung und stellt einen weiteren Teil der Anordnung dar. Es besteht aus einem Grundkörper, an dessen Oberfläche mehrere Führungskonturen 9 zum Führen des Bügelelements 5 ausgebildet sind. Aufgrund unterschiedlicher Gehäusebauformen - insbesondere unterschiedlicher Gehäusebreiten der Elektroinstallationsgeräte 1 - ist es möglich, dass der Abstand A (siehe Fig. 5a und 5b) der Rastöffnungen 4 variiert. Durch die Anordnung mehrerer Führungskonturen 9 an dem Verschlusselement 8 wird es ermöglicht, die freien Enden 7 des Bügelelements 5 in Abhängigkeit des Abstandes A der Rastöffnungen 4 und damit in Abhängigkeit der Gehäusebauform des jeweiligen Elektroinstallationsgeräts 1 in jeweils der Position zu fixieren, in der die freien Enden 7 des Bügelelements 5 in die Rastöffnungen 4 eingreifen. FIG. 2 shows a closure element 8 in a perspective plan view. The closure element 8 is in the assembled state (see Fig. 3a / 3b ) is in operative connection with the bracket element 5 and represents a further part of the arrangement. It consists of a base body, on the surface of which a plurality of guide contours 9 for guiding the bracket element 5 are formed. Due to different housing designs - in particular different housing widths of the electrical installation devices 1 - it is possible that the distance A (see Fig. 5a and 5b ) of the latching openings 4 varies. By arranging a plurality of guide contours 9 on the closure element 8, it is possible to fix the free ends 7 of the bracket element 5 as a function of the distance A of the detent openings 4 and thus depending on the housing design of the respective electrical installation device 1 in each of the position in which the free Ends 7 of the bracket member 5 engage in the latching openings 4.

Bügelelement 5 und Verschlusselement 8 bildet zusammen eine Absperrvorrichtung 3 für das Elektroinstallationsgerät 1, eine sogenannte Griffsperre. Bei einer Vormontage der Griffsperre 3 wird das Bügelelement 5 mit dem Steg 6 voraus in das Verschlusselement 7 eingeführt. Um zu verhindern, dass sich das Bügelelement 5 von dem Verschlusselement 7 unbeabsichtigt löst, weist das Verschlusselement 7 zwei Rasthaken 11 auf. Diese stellen einen Vorsprung dar, der bei einem vormontierten Bügelelement 5 eine Hinterschneidung mit dem Steg 6 bildet und diesen somit am Lösen vom Verschlusselement 8 hindern.Ironing element 5 and closure element 8 together forms a shut-off device 3 for the electrical installation device 1, a so-called grip lock. In a pre-assembly of the handle lock 3, the bracket member 5 is inserted with the web 6 ahead in the closure element 7. To prevent yourself the bracket element 5 inadvertently releases from the closure element 7, the closure element 7 has two latching hooks 11. These represent a projection which forms an undercut with the web 6 in a preassembled yoke element 5 and thus prevent it from being released from the closure element 8.

Die Figuren 3a und 3b zeigen schematisch die vormontierte Absperrvorrichtung 3, bestehend aus dem drahtförmigen, federelastischen Bügelelement 5 und dem Verschlusselement 8, in zwei unterschiedlichen, perspektivischen Ansichten. Das Bügelelement 5 ist dabei teilweise innerhalb des Verschlusselements 8 angeordnet. Zur Führung des Bügelelements 5 weist das Verschlusselement 8 mehrere Führungskonturen 9 auf, mit deren Hilfe das federelastische Bügelelement 5 in einer definierten Position fixiert wird. Dabei weisen die Enden 7 des Bügelelements 5 in Abhängigkeit der verwendeten Führungskonturen 9 einen unterschiedlichen Abstand zueinander auf, welcher mit dem Abstand A (siehe Fig. 5a und 5b) der Rastöffnungen 4 korrespondiert. Auf diese Weise ist die Absperrvorrichtung 3 an die Gehäusebreite der Elektroinstallationsgeräte 1 anpassbar ist. Ferner weist die Absperrvorrichtung 3 eine Öffnung auf, welche von einer Aussparung 10 des Verschlusselements 8 und dem Steg 6 des Bügelelements 5 gebildet wird. Durch die Öffnung kann eine Verriegelung, beispielsweise ein Bügelschloss, geführt werden, wodurch ein unbefugtes Öffnen der Griffsperre 3 blockiert wird. Bei einer ausreichenden Höhe H der Führungskonturen 9 können auch Verriegelungsstifte oder Bügelschlösser verwendet werden, deren Durchmesser kleiner ist als der Durchmesser der durch die Aussparung 10 und den Steg 6 gebildeten Öffnung.The FIGS. 3a and 3b schematically show the pre-assembled shut-off device 3, consisting of the wire-shaped, resilient bracket member 5 and the closure member 8, in two different, perspective views. The bracket member 5 is partially disposed within the closure member 8. For guiding the stirrup element 5, the closure element 8 has a plurality of guide contours 9, by means of which the resilient stirrup element 5 is fixed in a defined position. In this case, the ends 7 of the stirrup element 5, depending on the guide contours 9 used a different distance from each other, which with the distance A (see Fig. 5a and 5b ) of the latching openings 4 corresponds. In this way, the shut-off device 3 is adaptable to the housing width of the electrical installation devices 1. Furthermore, the shut-off device 3 has an opening which is formed by a recess 10 of the closure element 8 and the web 6 of the bracket element 5. Through the opening, a lock, such as a padlock, are guided, whereby an unauthorized opening of the handle lock 3 is blocked. With a sufficient height H of the guide contours 9 also locking pins or U-locks can be used, whose diameter is smaller than the diameter of the opening formed by the recess 10 and the web 6.

Die Figuren 4a und 4b zeigen schematische Darstellungen der Absperrvorrichtung 3 beim Anbringen an ein Elektroinstallationsgerät 1, jeweils in einer perspektivischen Ansicht. Dabei sind das Bügelelement 5 und das Verschlusselement 8 bereits zur Griffsperre 3 vormontiert.The FIGS. 4a and 4b show schematic representations of the shut-off device 3 when attached to an electrical installation device 1, each in a perspective view. In this case, the bracket element 5 and the closure element 8 are already preassembled for the handle lock 3.

In Figur 4a sind die freien Enden 7 des Bügelelements 5 aufgrund seiner Eigenelastizität bereits in die Rastöffnungen 4 des Elektroinstallationsgeräts 1 eingesteckt. Das Verschlusselement 8 befindet sich relativ zum Bügelelement 5 noch in einer ersten Position, in der die Führungskonturen 9 das Bügelelement 5 noch nicht fixieren, so dass die Kopplung des Bügelelements 5 mit den Rastöffnungen 4 durch Zusammendrücken des Bügelelements 5 im Bereich der freien Enden 7 wieder gelöst werden kann. In dem den Führungskonturen 9 abgewandten Bereich des Verschlusselements 8 ist die Aussparung 10 zu erkennen. Diese bildet in der ersten Position jedoch noch keine Öffnung mit dem Steg 6 des Bügelelements 5.In FIG. 4a the free ends 7 of the bracket member 5 are already plugged into the locking openings 4 of the electrical installation device 1 due to its inherent elasticity. The closure element 8 is still relative to the bracket element 5 in a first position in which the guide contours 9, the bracket member 5 is not yet fixed, so that the coupling of the bracket member 5 with the locking holes 4 by squeezing the bracket member 5 in the region of the free ends 7 again can be solved. In the region of the closure element 8 facing away from the guide contours 9, the recess 10 can be seen. However, in the first position, this still does not form an opening with the web 6 of the bracket element 5.

In Figur 4b ist das Verschlusselement 8 relativ zum Bügelelement 5 nach oben verschoben dargestellt. Das Verschlusselement 8 befindet sich in einer zweiten Position, in der die Führungskonturen 9 derart auf das Bügelelement 5 wirken, dass die freien Enden 7 in den Rastöffnungen 4 fixiert werden. Ein Lösen der Kopplung des Bügelelements 5 mit den Rastöffnungen 4 durch Zusammendrücken des Bügelelements 5 im Bereich der freien Enden 7 ist somit nicht möglich. In dieser zweiten Position, in der das Bügelelement 5 tiefer in das Verschlusselement 8 eingetaucht ist, bildet die Aussparung 10 zusammen mit dem Steg 6 eine Öffnung, welche beispielsweise mit einem Bügelschloss gegen unbeabsichtigtes Öffnen der Griffsperre 3 gesichert werden kann. Indem die Führungskonturen 9 eine Höhe aufweisen, welche den Durchmesser des drahtförmigen Bügelelements 5 deutlich übersteigt, ist die Öffnung, welche von der Aussparung 10 und dem Steg 6 gebildet wird, unterschiedlich groß dimensionierbar, je nachdem wie tief das Bügelelement 5 in das Verschlusselement 8 eintaucht. Auf diese Weise können Bügelschlösser mit unterschiedlichen Bügeldurchmessern zum Absperren der Absperrvorrichtung 3 verwendet werden. Hierdurch sind unterschiedlich große Bügelschlösser, beispielsweise mit einem Bügeldurchmesser von 3mm bis 6mm, einsetzbar. Auf diese Weise wird die Teilevielfalt bei der Montage weiter verringert.In FIG. 4b the closure element 8 is shown displaced relative to the bracket member 5 upwards. The closure element 8 is in a second position, in which the guide contours 9 act on the bracket element 5 such that the free ends 7 are fixed in the latching openings 4. A release of the coupling of the bracket member 5 with the locking holes 4 by squeezing the bracket member 5 in the region of the free ends 7 is thus not possible. In this second position, in which the bracket element 5 is immersed deeper into the closure element 8, the recess 10 forms together with the web 6 an opening which can be secured, for example with a padlock against unintentional opening of the handle lock 3. By the guide contours 9 have a height which exceeds the diameter of the wire-shaped bracket member 5 significantly, the opening, which is formed by the recess 10 and the web 6, dimensioned differently large, depending on how deep the bracket member 5 is immersed in the closure member 8 , In this way, U-locks with different bracket diameters can be used to shut off the shut-off device 3. As a result, different size padlocks, for example, with a strap diameter of 3mm to 6mm, can be used. In this way, the variety of parts during assembly is further reduced.

Der Betätigungsgriff 2 ist in den Figuren 4a und 4b in einer unteren Stellung dargestellt; es ist jedoch mit Hilfe der Griffsperre 3 ebenso möglich, das Betätigen des Betätigungsgriffs 2 in einer oberen Stellung des Betätigungsgriffs 2 zu blockieren.The operating handle 2 is in the FIGS. 4a and 4b shown in a lower position; However, it is also possible with the help of the handle lock 3, to block the actuation of the operating handle 2 in an upper position of the operating handle 2.

In den Figuren 5a und 5b ist die Griffsperre 3 an Elektroinstallationsgeräten 1 unterschiedlicher Breite angeordnet dargestellt, wobei das Verschlusselement 8 relativ zum Bügelelement 5 jeweils die zweite Position (siehe Figur 4b) einnimmt.In the FIGS. 5a and 5b the handle lock 3 is shown arranged on electrical installation equipment 1 different width, wherein the closure member 8 relative to the bracket member 5 respectively the second position (see FIG. 4b ) occupies.

Figur 5a zeigt die Absperrvorrichtung 3 an einer schmalen Ausführung des Elektroinstallationsgerätes 1. Da bei dieser Bauform der Abstand der Rastöffnungen 4 klein ist, werden zur Führung des Bügelelements 5 die inneren Führungskonturen 9 des Verschlusselements 8 verwendet, um die freien Enden 7 des federelastischen Bügelelements 5 in den Rastöffnungen 4 zu fixieren. FIG. 5a shows the shut-off device 3 on a narrow version of the electrical installation device 1. Since in this design, the distance of the detent openings 4 is small, the inner guide contours 9 of the closure member 8 are used to guide the bracket member 5 to the free ends 7 of the resilient bracket member 5 in the Locking openings 4 to fix.

Im Gegensatz dazu ist die Absperrvorrichtung 3 in Figur 5b an einer breiteren Ausführung des Elektroinstallationsgerätes 1 angeordnet dargestellt. Da bei dieser Ausführung die Rastöffnungen 4 weiter voneinander beabstandet sind, werden zur Führung des Bügelelements 5 die äußeren Führungskonturen 9 verwendet, um die freien Enden 7 des Bügelelement 5 in den weiter voneinander beabstandeten Rastöffnungen 4 zu fixieren.In contrast, the shut-off device 3 is in FIG. 5b shown arranged on a wider version of the electrical installation device 1. Since in this embodiment, the detent openings 4 are further spaced from each other, the outer guide contours 9 are used to guide the bracket member 5 to fix the free ends 7 of the bracket member 5 in the further spaced apart detent openings 4.

Auf diese Weise kann mit ein und derselben Absperrvorrichtung 3 ein Betätigungselement 2 eines Elektroinstallationsgeräts 1 unabhängig von der Gehäusebauform, d.h. unabhängig von der Gehäusebreite des Elektroinstallationsgeräts 1 blockiert werden. Hierdurch wird die Variantenvielfalt deutlich reduziert. Sowohl die Montage von Bügelelement 5 und Verschlusselement 8 zur Absperrvorrichtung 3, als auch die Montage der vormontierten Absperrvorrichtung 3 am Elektroinstallationsgerät 1 kann dabei ohne Verwendung von Werkzeugen erfolgen. Der der Montageaufwand wird dadurch deutlich vereinfacht.In this way, with one and the same shut-off device 3, an actuating element 2 of an electrical installation device 1, regardless of the housing design, ie blocked independently of the housing width of the electrical installation device 1. As a result, the variety of variants is significantly reduced. Both the mounting of bracket element 5 and closure element 8 to the shut-off device 3, as well as the installation of the pre-assembled Shut-off device 3 on the electrical installation device 1 can be done without the use of tools. The assembly effort is significantly simplified.
