Abstract
Schaltwerk für einen Ewigen Kalender bestehend aus einer Monatsscheibe (1), einer Tagesscheibe (2), einem Schalthebel (3) mit Schaltfinger (4), der einmal am Tag um 360° im Uhrzeigersinn gedreht wird und dabei an den Ränder beider Scheiben entlang läuft und einer Nutenscheibe (5), in deren Nuten der Schaltfinger bei seiner Bewegung radial geführt wird und dabei den Schaltvorgang auslöst.Derailleur for a perpetual calendar consisting of a monthly disc (1), a disc (2), a shift lever (3) with shift finger (4), which is rotated once a day by 360 ° clockwise while running along the edges of both discs and a Nutenscheibe (5), in whose grooves the shift finger is guided radially during its movement and thereby triggers the switching operation.
Description
Es gibt für mechanische Armbanduhren eine Reihe von ihnen mit einem ,Ewigen Kalender'. Diese Uhren haben ein Schaltwerk, das immer den richtigen Monat und den richtigen Tag anzeigt – unabhängig von der Monatslänge des jeweiligen Monats und unabhängig davon, ob es sich jeweils um ein Schaltjahr oder ein Nichtschaltjahr handelt. Bei den Uhren mit ,Ewigen Kalendern' der herkömmlichen Bauart besteht das Schaltwerk aus sehr vielen Teilen (ca. 80–100 Teile). Die Aufgabe der Erfindung ist, die für das Schaltwerk benötigte Teilezahl zu reduzieren. Gemäß der Erfindung wird das Schaltwerk auf 4 Monatswechsel-Schaltfälle zurückgeführt.There are a number of them with a 'perpetual calendar' for mechanical wristwatches. These watches have a rear derailleur that always displays the correct month and day, regardless of the length of the month, regardless of whether it is a leap year or a non-leap year. In the watches with 'perpetual calendars' of the conventional design, the rear derailleur consists of many parts (about 80-100 parts). The object of the invention is to reduce the number of parts required for the rear derailleur. According to the invention, the derailleur is returned to 4-month switching cases.
Es gibt 4 Monatswechsel-Schaltfälle:
In all diesen Fällen werden der Tag auf ‚1' und der Monat auf den nächsten Monat geschaltet – in allen anderen Fällen wird nur der Tag auf den nächsten Tag geschaltet.In all these cases, the day is switched to '1' and the month to the next month - in all other cases, only the day is switched to the next day.
Nachfolgend wird die Erfindung an 2 Ausführungsbeispielen näher erläutert:The invention will be explained in more detail below with reference to two exemplary embodiments:
