Description

  

      Zusatzpatent    zum Hauptpatent Nr. 125806.    Halter für     Kollektorbürsten.       Wird bei Bürstenhaltern nach dem Haupt  patent der Druckhebel 4 von Hand in die Be  triebslage nach     Fig.    1. gebracht, so besteht  das Risiko, dass versehentlich das Gehäuse  durch dessen Oberteil geschlossen wird, ohne  dass die erstere Operation, das heisst die     An-          legung    des Druckhebels vorgenommen wurde.  



  Erfindungsgemäss wird eine :Schliessung  des Gehäuses ohne vorherige Einstellung  des Druckhebels dadurch verunmöglicht, dass  mit der     Schliessbewegung    des Gehäuseober  teils zugleich der Druckhebel automatisch       betätigt    wird.  



  Eine beispielsweise Ausführungsform ist  in der Zeichnung dargestellt, wobei die Be  zugszeichen des Hauptpatentes beibehalten  sind. Am Gehäuseoberteil 7 ist ein Nocken  10 derart angeordnet, dass derselbe durch  den aufgeklappten Gehäuseoberteil blockiert  wird. Sinngemäss wird beim Schliessen des  Oberteils     der    Druckhebel zwangsweise in die    Betriebslage bewegt, mindestens so weit, bis  die selbsttätige Weiterbewegung durch die  wirksam werdende Zugkraft der Feder  gesichert ist. Im Bedarfsfalle kann noch eine  Einrichtung vorgesehen sein, die bewirkt,  dass beim Öffnen des Gehäuses die Abhebung  des Druckhebels 4     ebenfalls    selbsttätig er  folgt. In der Zeichnung übernimmt diese  Funktion der punktiert eingezeichnete Mit  nehmer     10a.  



      Additional patent to main patent no. 125806. Holder for collector brushes. If, in the case of brush holders according to the main patent, the pressure lever 4 is brought into the operating position according to FIG. 1 by hand, there is a risk that the housing will inadvertently be closed by its upper part without the first operation, i.e. the application the pressure lever has been made.



  According to the invention, the closing of the housing without prior adjustment of the pressure lever is made impossible in that the pressure lever is automatically actuated at the same time as the closing movement of the upper part of the housing.



  An example embodiment is shown in the drawing, the reference numerals of the main patent being retained. A cam 10 is arranged on the upper housing part 7 in such a way that it is blocked by the upper housing part that has been opened. Analogously, when the upper part is closed, the pressure lever is forcibly moved into the operating position, at least until the automatic further movement is secured by the tensile force of the spring that becomes effective. If necessary, a device can also be provided which has the effect that when the housing is opened, the pressure lever 4 is also automatically lifted off. In the drawing, this function is taken over by the dotted line driver 10a.
