Description

Die Erfindung betrifft einen Schalthebel für elektromechanische Schaltuhren, der von den programmierten Schaltnocken der Schaltreiter auf einer umlaufenden Zeitscheibe, oder manuell, beaufschlagt, einen elektriischen Schalter, mittelbar über einen Schaltstern, ein-, aus- oder umschaltet.The invention relates to a switch lever for electromechanical timers, which is acted upon by the programmed switching cams of the switch tabs on a rotating time slice, or manually, and switches an electrical switch on, off or on indirectly via a switching star.

Bei derartigen Schaltuhren ist zur zeitgesteuerten und/oder manuellen, mittelbaren Betätigung eines elektrischen Schalters ein Schalthebel erforderlich, der nicht nur wenig Platz in Anspruch nimmt, sondern der auch einen elektrischen Schalter, unabhängig vom der Geschwindigkeit mit der der Hebel zeitgesteuert oder manuell beaufschlagt wird, momentan schaltet.Such timers require a time-controlled and / or manual, indirect actuation of an electrical switch, which not only takes up little space, but also an electrical switch, regardless of the speed at which the lever is time-controlled or manually operated, is currently switching.

Es ist bei derartigen Schaltuhren bekannt, zur Erfüllung dieser Erfordernisse Schalthebel einzusetzen, die zur mittelbaren Betätigung eines elektrischen Schalters vorgesehen sind und die sowohl zeitgesteuert, durch die Schaltnocken der Programmierten Schaltreiter oder manuell beaufschlagbar sind.In such time switches it is known to use switching levers to meet these requirements, which are provided for the indirect actuation of an electrical switch and which are both time-controlled, can be acted upon by the switching cams of the programmed switching tabs or manually.

Bei diesen bekanntgewordenen Schalthebeln handelt es sich teilweise um relativ komplizierte Bauelemente, häufig um metallene Sprungfederelemente, welche eine aufwendige Montagejustierung erforderlich machen. Außerdem ist bei einer Vielzahl derartiger Schalthebel der Platzbedarf in einer Schaltuhr relativ groß.These shift levers, which have become known, are in some cases relatively complicated components, often metal spring elements, which make complex assembly adjustment necessary. In addition, with a large number of such shift levers, the space requirement in a time switch is relatively large.

Der Erfindung liegt die Aufgabe zugrunde, einen Schalthebel zu schaffen, der rationell herstellbar und einfach, ohne Justage montierbar ist und der sicherstellt, daß ein elektrischer Schalter, unabhängig von der jeweiligen zeitgesteuerten oder manuell bewirkten Betätigungsgeschwindigkeit, momentan geschaltet, d.h. abrupt, geschaltet wird.The invention has for its object to provide a shift lever which can be produced efficiently and easily, can be assembled without adjustment and which ensures that an electrical switch, regardless of the respective time-controlled or manually actuated actuation speed, is currently switched, i.e. abruptly, is switched.

Diese Aufgabe wird mit den Merkmalen im kennzeichnenden Teil des Schutzanspruchs 1 gelöst und in den Unteransprüchen sind weitere vorteilhafte Einzelheiten beansprucht.This task is carried out with the features in the characterizing part of the protection claim 1 solved and further advantageous details are claimed in the subclaims.

Vorteilhaft bei diesem Schalthebel ist nicht nur, daß dieser einfach und rationell, insbesondere einstückig, räumlich relativ flach, aus Kunststoff herstellbar ist, sondern daß mit diesem Schalthebel in Zusammenwirkung mit einem mittelbaren Schaltstern, ein elektrischer Schalter, unabhängig von der jeweiligen Betätigungsgeschwindigkeit, momentan umschaltbar ist. Vorteilhaft ist ferner die einstückig integrierte Doppelklinkenanordnung am Schalthebel, für den Eingriff mit dem Schalthebel.The advantage of this shift lever is not only that it can be manufactured simply and efficiently, in particular in one piece, spatially relatively flat, from plastic, but that with this shift lever, in cooperation with an indirect shift star, an electrical switch, regardless of the respective actuation speed, can currently be switched is. The one-piece integrated pawl arrangement on the shift lever is also advantageous for engagement with the shift lever.

Es ist natürlich möglich, daß eine entsprechende Feder erforderlichenfalls auch als Zug- oder Druckfeder ausgebildet ist. Auch ist es vorgesehen, daß eine solche Zug- oder Druckfeder im Bereich des Bolzens 14 am Schalthebel 1 angreifen kann.The two pawls 7 and 8 connected to one another via the web 9 are connected to the switching lever 1 on the front side via a further hinge-like web 16. 17 shows a return spring, which is designed as a leaf spring, which is mounted in a radial parallel guide 18 on the timer housing 3. It is of course possible that a corresponding spring is also designed as a tension or compression spring if necessary. It is also provided that such a tension or compression spring can act on the shift lever 1 in the region of the bolt 14.

19 kennzeichnet eine vorgesehene manuelle Betätigungstaste, mittels der eine Schaltungsvorwahl des elektrischen Schalters 13 unmittelbar über den Schalthebel 1 vorgenommen werden kann. Unabhängig davon ist es jedoch auch möglich, die manuelle Schaltungsvorwahl an einem Drehknopf 20 auf dem Schaltstern 12 vorzunehmen.19 identifies a provided manual actuation button, by means of which the electrical switch 13 can be preselected directly via the shift lever 1. Irrespective of this, however, it is also possible to make the manual circuit preselection using a rotary knob 20 on the switching star 12.
