Abstract

The invention relates to an electrical device, especially a protective switch, which comprises a switch latch having a control button that can be especially swiveled or displaced and that can be coupled with movable contacts of a contact device. The switch further comprises a jack that is coupled with the control button and that is movably mounted. A jack support is associated with said jack and is movably mounted in the switch latch, said jack support being associated with the trigger element of a trigger. The movability of the jack support can be blocked by an arbitrarily actuated locking element.

In Fig. 1 bis 5 ist ein elektrisches Gerät 1, ein Schaltschloss 2 und einen Betätigungsknopf 3 umfassend, der an einer Schlossplatte 1.1 schwenkbar gelagert ist, dargestellt. Der Betätigungsknopf 3 ist mechanisch über einen Kniehebel 18 mit beweglichen Kontakten 4 eines Kontaktapparates 5 verbunden. Weiters ist mit dem Betätigungsknopf 3 auch eine Klinke 6 gekuppelt, die ihrerseits ebenfalls schwenkbar an der Schlossplatte 11 gelagert ist. Dieser Klinke 6 ist eine schwenkbar gelagerte Klinkenauflage 7 zugeordnet, wobei vorgesehen ist, dass in Arbeitsstellung des elektrischen Schalters 1 die Klinke 6 an der Auflagefläche 13 der Klinkenauflage 7 aufliegt bzw. eingreift. Das der Auflagefläche 13 gegenüberliegende Ende der Klinkenauflage 7, der Ansatz 17, ist dem Auslöseelement 8 eines Auslösers 9 zugeordnet, welche beide in Fig. 3 gezeigt sind. Die Klinkenauflage 7 ist durch ein willkürlich betätigbares Arretierungselement 10 blockierbar angeordnet. Eines oder mehrere der Elemente Betätigungsknopf 3, Klinke 6 oder Klinkenauflage 7, können auch translatorisch verschiebbar gelagert sein, wobei es nicht erfindungswesentlich ist, wieviele oder welche dieser Elemente in welcher Art und Kombination bewegbar gelagert sind. Der Auslöser 9 ist als Permanentmagnetauslöser und das Auslöseelement 8 als Auslösestössel des Permanentmagnetauslösers dargestellt, aber auch andere Arten von Auslösern, wie z.B. Bimetallauslöser, Spulen mit Anker oder dgl. können Bestandteil des elektrischen Geräts 1 sein.In Fig. 1 to 5, an electrical device 1, a switching mechanism 2 and an operating knob 3 comprising, which is pivotally mounted on a lock plate 1.1, shown. The operating knob 3 is mechanically connected via a toggle lever 18 with movable contacts 4 of a contact apparatus 5. Furthermore, with the operation knob 3 and a pawl 6 is coupled, which in turn is also pivotally mounted on the lock plate 11. This pawl 6 is associated with a pivotally mounted latch support 7, wherein it is provided that in the working position of the electrical switch 1, the pawl 6 rests on the support surface 13 of the latch support 7 and engages. The support surface 13 opposite the end of the latch support 7, the lug 17, the trigger element 8 of a Trigger 9 assigned, both of which are shown in Fig. 3. The latch support 7 is arranged blockable by an arbitrarily actuable locking element 10. One or more of the elements actuating button 3, pawl 6 or pawl support 7, can also be mounted translationally displaceable, wherein it is not essential to the invention, how many or which of these elements are movably mounted in what kind and combination. The trigger 9 is shown as a permanent magnet release and the trigger element 8 as a trigger push rod of the permanent magnet release, but also other types of triggers, such as bimetallic triggers, coils with anchor or the like. May be part of the electrical device 1.
Im Falle der Aktivierung des Auslösers 9, beispielsweise durch Erreichung einer vorgegebenen Spannung, drückt das Auslöseelement 8 gegen den Ansatz 17 der Klinkenauflage 7, die dadurch derart gegen die Kraft einer Feder 20 bewegt wird, dass die Klinke 6 außer Eingriff der Klinkenauflage 7 gerät und so in an sich bekannter Weise den elektrischen Schalter 1 in Ruhestellung verbringt. Es kann weiters ein Rücksteller 16 vorgesehen sein, der nach der Aktivierung des Auslösers 9 das Auslöseelement 8 durch Federwirkung wieder in die Ausgangsstellung verbringt.In the case of activation of the trigger 9, for example, by reaching a predetermined voltage, the trigger element 8 presses against the lug 17 of the pawl 7, which is thereby moved against the force of a spring 20, that the pawl 6 disengages the pawl rest 7 and so in a conventional manner the electrical switch 1 spends at rest. It can also be provided a reset 16, which spends after the activation of the trigger 9, the trigger element 8 by spring action back into the starting position.
Fig. 2 und Fig. 3 zeigen das Arretierungselement 10 in Form eines zweiarmigen Hebels, dessen eines Ende dem Ansatz 17 der Klinkenauflage 7 zugeordnet ist. Das andere Ende des Arretierungselemtes 10 umfasst eine Durchbrechung 15 und ist willkürlich betätigbar. Das Arretierungselement 10 ist hierbei im wesentlichen parallel zur Schlossplatte 11 verschwenkbar angeordnet. Durch willkürliche Betätigung des Arretierungselements 10 bewegt das eine Ende 10' des Arretierungselements 10 den Ansatz 17 der Klinkenauflage 7 in gleicher Weise wie das Auslöseelement 8 und bringt somit die Klinke 6 außer Eingriff der Klinkenauflage 7. Der Ansatz 7 kann hierbei durch einen Schlitz 12 der Schlossplatte 11 geführt sein.Fig. 2 and Fig. 3 show the locking element 10 in the form of a two-armed lever, one end of which is associated with the lug 17 of the latch support 7. The other end of the Arretierungselemtes 10 includes an opening 15 and is arbitrarily actuated. The locking element 10 is in this case arranged substantially parallel to the lock plate 11 pivotally. By arbitrary actuation of the locking element 10 moves the one end 10 'of the locking element 10 the lug 17 of the latch support 7 in the same manner as the trigger element 8 and thus brings the pawl 6 out of engagement of the latch support 7. The approach 7 can in this case by a slot 12 of Lock plate 11 be guided.
Das Arretierungselement 10 kann hierbei entweder direkt manuell an seinem anderen Ende 10" betätigt werden (siehe Fig. 2, 3 und 5), oder aber durch ein weiteres Betätigungselement 21 an seinem anderen Ende 10" betätigt werden.The locking element 10 can either be operated directly manually at its other end 10 "(see FIGS. 2, 3 and 5), or be actuated by a further actuating element 21 at its other end 10".
Um das Arretierungselement 10 wohldefiniert in eine Schaltposition verbringen zu können, ist an einem Deckel 19 des elektrischen Geräts 1 eine Rastenleiste 14 angeordnet, die ein Verrasten des Arretierungselements 10 in der jeweiligen Position sicherstellt (vgl. Fig. 2). Weiters ist am willkürlich betätigbaren Ende des Arretierungselements 10 eine Durchbrechung 15 ausgeführt, die für die Aufnahme beispielsweise von Plombierungen geeignet ist. Am Deckel 19 sind ebenfalls zwei Durchbrechungen 15' ausgeführt, von denen jeweils eine mit der Durchbrechung 15 des Arretierungselements 10 fluchtet, je nach Schaltposition des Arretierungselements 10.In order to be able to spend the locking element 10 well-defined in a switching position, a detent strip 14 is arranged on a cover 19 of the electrical device 1, which ensures a locking of the locking element 10 in the respective position (see Fig. 2). Furthermore, at the arbitrarily actuated end of the locking element 10, an opening 15 is executed, which is for receiving, for example, plumbing suitable is. On the cover 19 are also two openings 15 'executed, of which each one aligned with the opening 15 of the locking element 10, depending on the switching position of the locking element 10th
Das Arretierungselement 10 kann auch längs seiner Achse verschiebbar ausgebildet sein (vgl. Fig. 5). Anhand dieser Ausführungsform wird weiters gezeigt, dass eine Rastenleiste 14 auch im Inneren des elektrischen Geräts 1 angeordnet werden kann.. The locking element 10 may also be designed to be displaceable along its axis (cf., FIG. 5). Based on this embodiment, it is further shown that a catch bar 14 can also be arranged in the interior of the electrical device 1.
