 Richtung dreht. 



   Die   Umschaltungsvorrichtung   wirkt auch dann in der beschriebenen Weise, wenn das Stundenrad mit der Rolle 4 im entgegengesetzten Sinne gedreht wird, wie es z. B. beim Stellen der Zeiger der Uhr vorkommt. 



   Bei der beschriebenen   Umschaltung des   Zifferblattes übt das Stundenrad einen Druck auf die Minutenradwelle aus. Es ist daher notwendig, die Minutenradwelle vom Stundenrade frei zu   machen.   Dies wird dadurch erzielt, dass die Büchse des Stundenrades, mit welcher das Stundenrad in der Brücke 13 gelagert ist, mit einem grösseren inneren Durchmesser ausgestaltet ist, als der Durchmesser der Minutenradwelle. 
 EMI2.2 
 
1.   Umsehaltvorrichtung für   das Zifferblatt von Uhren mit   24-Stunden-Anzeige, dadurch gekenn-   zeichnet, dass sowohl beim normalen Ablauf, wie beim   Rückstellen   der Uhr das Stundenrad mittels einer Feder eine plötzliche, als auch zwangsläufig eine allmähliche Umschaltung des Zifferblattes bewirkt.

 Direction turns.



   The switching device also works in the manner described when the hour wheel is rotated with the roller 4 in the opposite direction, as it is, for. B. occurs when setting the hands of the clock.



   When switching the dial as described, the hour wheel exerts pressure on the minute wheel shaft. It is therefore necessary to free the minute wheel shaft from the hour wheel. This is achieved in that the sleeve of the hour wheel, with which the hour wheel is mounted in the bridge 13, is designed with a larger inner diameter than the diameter of the minute wheel shaft.
 EMI2.2
 
1. Changeover device for the dial of clocks with a 24-hour display, characterized in that both during normal operation and when resetting the clock, the hour wheel by means of a spring causes a sudden and inevitably a gradual changeover of the dial.

Claims (1)

2. Umsehaltvorrichtung nach Anspruch 1, gekennzeichnet durch einen vom Stundenrad verschwenken Hebel (5), der eine durch Federkraft aufrichtbare Klinke (6) trägt, die in einen schwenkbaren, M-förmigen Teil (7) greift und diesen in dem einen oder dem andern Sinne verschwenkt. 2. Umsehaltvorrichtung according to claim 1, characterized by a pivot from the hour wheel lever (5) which carries a pawl (6) which can be erected by spring force, which engages in a pivotable, M-shaped part (7) and this in one or the other Senses pivoted. 3. Umschaltvorrichtung nach den Ansprüchen 1 und 2, dadurch gekennzeichnet, dass der M-förmige Teil (7) durch eine Feder (9) derart beeinflusst wird, dass er nach seiner Verschwenkung über seine Mittellage von der sich entspannenden Feder weiter verdreht wird, bis der eine der beiden äusseren Schenkel des Teiles (7) an einem Arm (14) des Zifferblattes stösst und diesen versehwenkt. EMI2.3 3. Switching device according to claims 1 and 2, characterized in that the M-shaped part (7) is influenced by a spring (9) in such a way that it is further rotated by the relaxing spring after being pivoted through its central position one of the two outer legs of the part (7) hits an arm (14) of the dial and pivots it.
