Description
Kleinschnellschalter Das Hauptpatent bezieht sich auf einen Kleinschnellschalter für elektrische Haus-und Gewerbeanlagen, der unter dem Einfluß zweier mechanisch hintereinander oder parallel geschalteter Verklinkungen steht, von denen die eine bei der selbsttätigen Auslösung freigegeben wird und die andere, welche vorzugsweise die Form eines Kniehebels besitzt, nach dem Einschalten das Verbleiben der zum Einschalten dienenden Handhabe in der Einschaltstelle bewirkt. Das Kennzeichen der Erfindung des Hauptpatents besteht darin, daß wenigstens die eine dieser Verklinkungen sich innerhalb der im Einschaltzustand bestehenden kraftschlüssigen Verbindung zwischen der Kontaktstelle und der den Kontaktdruck erzeugenden Federung befindet, welche selbst ein Kraftübertragungsglied in der kraftschlüssigen Verbindung zwischen der Kontaktstelle und dem Schalterantrieb beim Einschalten bildet: Im Hauptpatent ist ein derartiger Schalter als Ausführungsbeispiel näher beschrieben. Bei diesem ist die auslösbare Verklinkung zwischen einem von der Handhabe angetriebenen Glied des Schaltmechanismus und einem mit den Schaltorganen beweglichen Glied angeordnet. Sie ist an -dem -einen der beiden Glieder drehbar gelagert und mit dem anderen lösbar gekuppelt, derart, daß der Antrieb des Schaltorgans in die Einschaltstellung über die Verklinkung erfolgt und die Lagerung der Klinke bei den verschiedenen Schaltvorgängen .eine Hinundherbewegung ausführt. Weitere Ausführungsformen solcher Schalter, die sich besonders durch große Einfachlieit ihres Aufbaues auszeichnen, lassen sich erfindungsgemäG. dadurch schaffen, daß das unter Einwirkung der Ausschaltfeder stehende Schaltglied der beweglichen Kontaktbrücke von eitlem Hebel in der Einschaltstellung gehalten wird, der sich mit einem Ende gegen eine beweglich gelagerte Klinke ,abstützt, deren Lager von einer den Kontaktdruck @erzeugenden Federung getragen wird, während an dem anderen Ende des Hebels der Hand-<äntrieb angreift.Miniature quick switch The main patent relates to a miniature quick switch for electrical house and commercial systems, which is under the influence of two mechanical one behind the other or in parallel connected latches, one of which when the automatic release is released and the other, which is preferred has the shape of a toggle lever, after switching on the remaining to switch on serving handle causes in the switch-on. The characteristic of the invention of the main patent is that at least one of these latches within the frictional connection between the contact point and the spring generating the contact pressure, which itself a power transmission member in the frictional connection between the Contact point and the switch drive when switching on forms: In the main patent is such a switch is described in more detail as an exemplary embodiment. With this one is the releasable latch between a member driven by the handle of the Switching mechanism and arranged with a movable member with the switching elements. It is rotatably mounted on one of the two links and detachable with the other coupled in such a way that the drive of the switching element in the switched-on position the latching takes place and the storage of the latch during the various switching operations .performs a reciprocating motion. Further embodiments of such Switches that are particularly characterized by their great simplicity of construction, can be according to the invention. thereby create that under the action of the opening spring standing switching element of the movable contact bridge of vain lever in the on position is held, which is supported with one end against a movably mounted pawl, whose bearing is supported by a spring which generates the contact pressure, while the hand drive engages at the other end of the lever.
Während bei dem Ausführungsbeispiel des Hauptpatents die Lagerung der Klinke beim Einschalten einen beträchtlichen Weg zurückzulegen hat und nur während der Durchdruckbewegung stillsteht, braucht sie bei einem Schalter nach der vorliegenden Erfindung gerade umgekehrt nur während der Durchdruckbewegung ihre Lage zu ändern und kann auf dem größten Teil des Schalterantriebsweges in Ruhe verbleiben. Dies bedeutet einen beachtlichen konstruktiven Vorteil, insbesondere im Hinblick darauf, daß die Auslöseorgane so angeordnet werden müssen, daß sie im Einschaltzustand unter ganz bestimmten Verhältnissen auf die Klinke einwirken.While in the embodiment of the main patent, the storage the pawl has to travel a considerable distance when switched on and only during the push-through movement is still, you need it in a switch according to the present Invention just the other way round to change their position only during the push-through movement and can remain at rest for most of the switch drive path. this means a considerable constructive advantage, especially with regard to that the trigger elements must be arranged so that they are under in the switched-on state act on the latch in very specific conditions.
Zur näheren Erläuterung der Erfindung sollen die Abbildungen dienen. Abb. i zeigt ein Ausführungsbeispiel eines Schalters nach der Erfindung in der Einschaltlage. Abb.2 zeigt die Ausschaltlage nach einer selbsttätigen Auslösung, Abb.3 die Ausschaltlage, die der Schalter nach erfolgter Ausschaltung von Hand einnimmt.The illustrations are intended to provide a more detailed explanation of the invention. Fig. I shows an embodiment of a switch according to the invention in the switched-on position. Figure 2 shows the switch-off position after an automatic release, Figure 3 the switch-off position, which the switch takes by hand after it has been switched off.
Der Schaltersockel, die Kappe und alle sonstigen für die Erläuterung der Erfindung nicht notwendigen Teile sind in der Darstellung fortgelassen. i ist das Schaltglied, das an seinem unteren Ende :die bewegliche Schaltbrücke :! trägt, welche mit ortsfesten Schaltstücken 3, a zusammenarbeitet. Das Schaltglied i steht unter Wirkung der Ausschaltfeder 5. Es wird iii der Einschaltstellung dadurch gehalten, daG. es mit seinem oberen . Ende an den Hebel 6 angelenkt ist, dessen linkes Ende sich gegen eine Auslöseklinke 7 abstützt und an dessen rechtem Ende über den gekrümmten Lenker 8 der Handantrieb angreift. Die Klinke ; besitzt bei 9 ein drehbewegliches Lager, das von einer im verklinkten Zustand des Schalters gespannten Feder i o, die an einem ortsfesten Teil i i befestigt ist, getragen wird. Der untere Teil 12 der Klinke kann von einem oder mehreren nicht mit dargestellten Auslöseorganen beeinflui:.t werden. Wird die Klinke im Liüksdrehsinnc bewegt, so erfolgt die Entklinkung der Teile 0 und ; . Am rechten Ende des Hebels 6 befindet sich eüi Totpunktgelenk, über welches der Handantrieb angreift. Es besteht in dem gekrümmten Lenker 8 und in der Kurbel 13, die mit dem Schaltknebel i q. gleichachsig gelagert ist. Der Gelenkzapfen 15 ragt in eine Aussparung des Knebels 14, so daß er durch diesen über einen Totgang mitgenommen wird. In der gezeichneten Einschaltstellung legt sich der gekrümmte Lenker 8 gegen die Lagerachse 16 des Knebels i q. an. In dieser Stellung bilden die Gelenkpunkte 15, 16 und 17 ein schmales Dreieck. Wird der Knebel i q. im Linksdrehsinne bewegt und der Zapfen 15 über die labile Lage hinausgeführt, so erfolgt eine sprungartige Entklinkung der Anordnung durch die Totpunktlage.The switch base, the cap and all other parts not necessary for explaining the invention are omitted from the illustration. i is the switching element that at its lower end: the movable switching bridge:! carries, which cooperates with stationary contact pieces 3, a. The switching element i is under the action of the switch-off spring 5. It is held in the switch-on position by daG. it with its upper. End is articulated to the lever 6, the left end of which is supported against a release pawl 7 and engages at the right end via the curved handlebar 8 of the manual drive. The handle ; has at 9 a rotatable bearing which is carried by a spring io which is tensioned in the latched state of the switch and which is attached to a stationary part ii. The lower part 12 of the pawl can be influenced by one or more triggering devices (not shown). If the pawl is moved in the left direction, the unlatching of parts 0 and; . At the right end of the lever 6 there is a dead center joint via which the manual drive engages. It consists in the curved handlebar 8 and in the crank 13, which is connected to the toggle i q. is coaxially mounted. The pivot pin 1 5 protrudes into a recess of the toggle 14 so that it is taken along by this over a backlash. In the switched-on position shown, the curved link 8 lies against the bearing axis 1 6 of the toggle i q. at. In this position, the hinge points 1 5, 16 and 17 form a narrow triangle. If the toggle i q. moved in the counterclockwise direction and the pin 15 is guided beyond the unstable position, the arrangement is suddenly unlatched through the dead center position.
In der in Abb.2 gezeigten Stellung des Schalters nach einer selbsttätigen Auslösung ist das linke Ende des Hebels 6 herabgefallen, während das Totpunktgelenk 8, 13 verklinkt ist. In der in Abb.3 dargestellten nach einer Ausschaltung von Hand eingenommenen Stellung ist das Totpunktgelenk entklinkt, während sich das linke Ende des Hebels 6 nach wie vor gegen die Klinke ; anlehnt.In the position of the switch shown in Fig. 2 after an automatic Triggering the left end of the lever 6 fell down while the dead center joint 8, 13 is latched. In the one shown in Fig. 3 after a manual switch-off In the assumed position, the dead center joint is unlocked, while the left one is End of the lever 6 still against the pawl; leans on.
Die Einschaltung mittels des Knebels 1.l kann nur von der in Abb. 3 gezeigten Stellung aus vorgenommen werden, nach einer selbsttätigen Auslösung muß also zwecks Einschaltens von Hand der Knebel zunächst im Linksdrehsinne bewegt werden, bis die in Abb.3 gezeigte Stellung erreicht ist. Bei darauffolgender Einschaltbewegung des Knebels 14. im Rechtsdrehsinne wird mittels des Lenkers 8 das rechte Ende des Hebels 6 nach aufwärts gezogen und so die Einschaltstellung wiederhergestellt. Hierbei wird auch die Feder io gespannt; diese bewegt sich zugleich mit der Klinke". und deren Lager 8 etwas nach abwärts. weckmäßig sind Mittel zur Führung der Bewegung des Hebels 6 beim Einschalten vorgesehen. Hierzu dient bei dem dargestellten Schalter ein Führungsschlitz i 9 in den seitlichen Lagerwänden der Schaltermechanik, in den der Gelenkzapfen 17 eingreift.Switching on by means of the toggle 1.l can only be carried out from the position shown in Fig. 3, after an automatic release, the toggle must first be turned counterclockwise to switch on by hand until the position shown in Fig. 3 is reached . With the subsequent switch-on movement of the toggle 14 in the clockwise direction, the right-hand end of the lever 6 is pulled upwards by means of the handlebar 8 and the switch-on position is thus restored. The spring is also tensioned here; This moves at the same time with the pawl ". and its bearing 8 slightly downwards. Means for guiding the movement of the lever 6 when switching on are provided. For this purpose, a guide slot i 9 in the side bearing walls of the switch mechanism is used in the switch shown the pivot pin 17 engages.
Die Marke 18 ist angegeben, um beim Vergleich der Abbildungen zu zeigen, in welcher Höhe die- Klinke 7 'mit dem Lager 9 und der Feder i o sich bei den verschiedenen möglichen Stellungen des Schalters befindet. Es ist ohne weiteres ersichtlich, daß die Be-,c-egungen des Klinkenlagers nur gering zu sein brauchen.The mark 18 is indicated to show when comparing the figures at what level the pawl 7 'with the bearing 9 and the spring i o are in the various possible positions of the switch. It is readily apparent that the movements of the pawl bearing need only be slight.
Auch bei diesem Schalter ist wie beim Gegenstand .des Hauptpatents der Vorteil gewahrt, daß die im Einschaltzustand den Kontaktdruck erzeugende Federung i o beim Ausschalten infolge einer selbsttätigen Auslösung nicht in unerwünschter Weise den Beginn der Schaltstückstreiuiung verzögern kann. Denn auch hier entspannt sich bei Freigabe des linken Endes des Hebels 6 durch die Klinke 7 die Kontaktdruckfeder io völlig unabhängig von dem Einsetzen der Schaltbewegung. Die Schaltfeder 5 kann sich daher gleich auf die Schaltstücke selbst ,auswirken, ohne daß hierbei die Kontaktdruckfeder noch einen Einfluß auf die Schaltstücke ausüben kann. Somit ist auch bei einem solchen Schalter die Eigenzeit außerordentlich kurz.This switch is like the subject of the main patent the advantage is preserved that the spring which generates the contact pressure in the switched-on state i o not undesired when switching off as a result of automatic tripping Way the beginning of the Contact piece stripping can delay. Because here, too, relaxes when the left end of the lever 6 is released by the pawl 7 the contact pressure spring io completely independent of the onset of the switching movement. The switching spring 5 can therefore have the same effect on the switching pieces themselves, without the contact pressure spring exerting any influence on the contact pieces can. The operating time is therefore extremely short even with such a switch.
