Description

Die Erfindung richtet sich auf einen Kalendermechanismus, insbesondere in modularer Bauweise, der auf Uhrwerke montierbar ist, insbesondere in Form eines ewigen Kalenders, welcher über ein Rad einer Uhr angetrieben ist, welches eine . Umdrehung in 24 Stunden ausführt, wobei die Anzeige getrennt für Einer und Zehner über eine bedruckte, mit einer Verzahnung versehene Anzeigescheibe erfolgt, und wobei ein Programmträger vorgesehen ist, der in 31 Tagen eine Umdrehung ausführt.The invention is directed to a calendar mechanism, in particular in a modular design, which is mountable on clockworks, in particular in the form of an eternal calendar, which is driven by a wheel of a clock, which is a. Rotation in 24 hours, the display being made separately for ones and tens over a printed gearing plate provided with a gearing, and providing a program carrier which makes one revolution in 31 days.

Derartige Kalendermechanismen sind in unterschiedlicher Bauweise bekannt, wobei der Datumsmechanismus bzw. das -werk über Hebel und Klinken mit sehr geringer Geschwindigkeit weitergeschaltet wird. Ein Kalendermechanismus gemäss dem Oberbegriff des Anspruchs 1 ist aus der CH 316 461 bekannt.Such calendar mechanisms are known in a variety of construction, wherein the date mechanism or mechanism is indexed by levers and pawls at a very low speed. A calendar mechanism according to the preamble of claim 1 is known from CH 316 461 known.

Bei einem derartigen Mechanismus muss man sowohl tägliche Schaltschritte als auch mehrere Tage übergreifende Schaltschritte (vom 30. über den 31. auf den 01. in "kurzen" Monaten und vom 28.02. bzw. 29.02. auf den 01.03.) realisieren, was üblicherweise durch Getriebe mit aussetzender Bewegung erfolgt.With such a mechanism, one has to realize both daily shift steps as well as shift steps that span several days (from the 30th to the 31st to the 1st in "short" months and from the 28th to the 29th of February to the 1st of March) Gearbox with intermittent movement takes place.

Zum Zweck der Einstellung des Kalenders bzw. zur gemeinsamen Korrektur aller Anzeigen wird ein von aussen zugänglicher manueller Korrekturdrücker verwendet, der über dieselben Hebel und Klinken auf das Datumswerk einwirkt, die im normalen Betrieb eine Schaltung mit relativ geringer Geschwindigkeit bewerkstelligen.For the purpose of setting the calendar or for the common correction of all displays an externally accessible manual correction lever is used, which acts on the same lever and pawls on the date, which accomplish in normal operation, a circuit at a relatively low speed.

Die bei der manuellen Korrektur auf den Mechanismus wirkenden Geschwindigkeiten streuen individuell sehr stark. Sie können Grössenordnungen erreichen, wo die an sich vorhandenen Rastfedern eine sichere Arretierung der Anzeigescheiben aufgrund von deren gegenüber normalen Zeigern erheblich größerer Trägheit nicht mehr gewährleisten, so dass es zum Überschleudem der Anzeigeelemente kommt.The velocities acting on the mechanism during the manual correction scatter individually very strongly. You can reach orders of magnitude, where the existing detent springs no longer ensure a secure locking of the display discs due to their compared to normal hands significantly greater inertia, so that it comes to Überschleudem the display elements.

Um diesem Problem beizukommen, könnte man die Rastfedern, die die Endstellung der Bewegung fixieren, mit einer erhöhten Federkraft ausbilden, wodurch aber die Drehmomentbelastung des Uhrwerks stark ansteigt, so dass Gangdauer und Ganggenauigkeit in erheblichem Maß absinken.To cope with this problem, one could form the detent springs, which fix the end position of the movement, with an increased spring force, whereby the torque load of the movement increases sharply, so that duration and accuracy fall significantly.

Hiervon ausgehend liegt der Erfindung die Aufgabe zugrunde, einen Datumsmechanismus der eingangs genannten Art so auszugestalten, dass ein Überschleudern verhindert wird, ohne dass die Gangdauer und -genauigkeit wesentlich beeinftusst wird.Proceeding from this, the invention has the object, a date mechanism of the type mentioned in such a way that overspinning is prevented without the gear duration and accuracy is substantially gestftusst.

Diese Aufgabe wird erfindungsgemäß durch einen Kalendermechanismus gemäss Anspruch 1 gelöst.This object is achieved by a calendar mechanism according to claim 1.

Erfindungsgemäß wird also die Gefahr eines Überschleuderns durch den Programmträger dadurch verhindert, dass dann, und nur dann, wenn die entsprechende Gefahr besteht, für eine zusätzliche Sperrung gesorgt wird. An den übrigen Tagen wirken die Sperrelemente nicht auf den Datumsmechanismus bzw. das Uhrwerk ein, so dass die Funktion des Uhrwerks anders als im Fall einer Erhöhung der Federkraft der Rastfedern völlig unbeeinflusst bleibt.According to the invention, therefore, the danger of overspinning by the program support is prevented by the fact that then, and only if the corresponding danger exists, is provided for an additional blockage. On the remaining days, the locking elements do not affect the date mechanism or the movement, so that the function of the movement remains completely unaffected, unlike in the case of an increase in the spring force of the detent springs.

Dabei kann vorgesehen sein, dass auf dem Programmträger zusätzliche Steuerelemente aufgebracht sind oder die Steuerelemente durch die Form des Programmträgers realisiert werden, wobei die Steuerelemente jeweils die Sperrelemente antreiben.It can be provided that additional controls are applied to the program support or the controls are realized by the shape of the program carrier, wherein the control elements each drive the locking elements.

In weiterer Ausgestaltung der Erfindung ist vorgesehen, dass das zusätzliche Sperrelement eine um eine Schwenklagerachse schwenkbare Klinke ist, die im nichtsperrenden Zeitraum mittels einer Feder außer Eingriff zur Verzahnung der Anzeigescheibe gehalten wird.In a further embodiment of the invention, it is provided that the additional blocking element is a pivotable about a pivot bearing axis pawl which is held in the non-blocking period by means of a spring out of engagement with the toothing of the indicator disc.

Bei einer anderen erfindungsgemäßen Ausgestaltung ist vorgesehen, dass eine der Rastfedern als Sperrelement einen mit dem Programmträger zusammenwirkenden Stift trägt und deren Biegepunkt so positioniert ist, dass der Stift eine die Sperr- und Lösefunktion ermöglichende Bahn beschreibt.In another embodiment according to the invention it is provided that one of the locking springs carries as a blocking element cooperating with the program support pin and the bending point is positioned so that the pin describes a locking and releasing function enabling path.

Nachfolgend wird die Erfindung anhand bevorzugter Ausführungsbeispiele in Verbindung mit der Zeichnung näher beschrieben. Dabei zeigen:

  • Fig. 1 bis 4 die für die Erfindung wesentlichen Teile des Datumsmechanismus mit der jeweils zugehörigen Ansicht der Anzeigescheiben in vier zeitlich aufeinander folgenden Phasen beim Umschalten der Zehner vom 29. auf den 30. und
  • Fig. 5 bis 7 entsprechende Darstellungen für das Umschalten der Einer vom 30. auf den 01. in kurzen Monaten.
The invention will be described in more detail below with reference to preferred embodiments in conjunction with the drawings. Showing:
  • Fig. 1 to 4 the essential for the invention parts of the date mechanism with the respective associated view of the display discs in four temporally successive phases when switching the tens from the 29th to the 30th and
  • Fig. 5 to 7 corresponding representations for switching the one from 30th to 01st in short months.

Eine in Fig. 1 bis 7 dargestellte erfindungsgemäße Datumsanzeige 1 umfasst zwei zueinander konzentrisch angeordnete und angetriebene Anzeigescheiben 2 und 3, erstere für die Zehner und letztere für die Einer des jeweiligen Tages im Monat.An in Fig. 1 to 7 illustrated date display 1 comprises two mutually concentrically arranged and driven display discs 2 and 3, the former for the tens and the latter for the one of each day of the month.

Ein an sich bekannter Programmträger 4 bewegt sich in Richtung des Pfeils 5 derart, dass er in 31 Tagen eine Umdrehung ausführt. Dem Programmträger 4 ist in an sich bekannter Weise eine Rastfeder 6 zugeordnet, welche mit einer Verzahnung 7 des Programmträgers 4 zusammenwirkt.A per se known program carrier 4 moves in the direction of arrow 5 such that it performs a revolution in 31 days. The program carrier 4 is associated with a detent spring 6 in a conventional manner, which cooperates with a toothing 7 of the program carrier 4.

Erfindungsgemäß ist eine weitere Rastfeder 8 vorgesehen, deren Rastkopf 11 auf ein mit der Anzeigescheibe 2 verbundenes Trieb 9 mit vier Zähnen einwirkt, wie dies in Fig. 1 dargestellt ist.According to the invention a further detent spring 8 is provided, the locking head 11 acts on a connected to the indicator disc 2 drive 9 with four teeth, as in Fig. 1 is shown.

Durch ein erstes radial vorstehendes Steuerelement 10 des Programmträgers 4 wird das Trieb 9 weitergedreht, wobei die Rastfeder 8 bzw. deren Rastkopf 11 außer Eingriff gebracht wird.By a first radially projecting control element 10 of the program carrier 4, the drive 9 is further rotated, wherein the detent spring 8 and its latching head 11 is disengaged.

Durch die Trägheit der Anzeigescheibe 2 legt sich der nächste Zahn des Triebes 9 an die hintere Flanke des radialen Steuerelements 10 an und bewegt sich über die vorgesehene Raststellung hinaus weiter (Fig. 2).Due to the inertia of the indicator disc 2, the next tooth of the drive 9 applies to the rear edge of the radial control element 10 and moves beyond the intended detent position further ( Fig. 2 ).

Bevor die Rastfeder 8 bzw. deren Rastkopf 11 in die nächste Lücke desBefore the detent spring 8 and the locking head 11 in the next gap of the

Triebes 9 und damit in eine Rastposition kommt, die dem folgenden (und damit nicht korrekten) Tag entspricht, kommt ein weiteres, radial vorstehendes Steuerelement 12 des Programmträgers 4 in Funktion mit einem Stift 13, der aus dem Rastkopf 11 der Rastfeder 8 herausragt, und drückt den Rastkopf 11 in die dem korrekten Tag entsprechende Lücke des Triebes 9 und blockiert so die Drehbewegung des mit der Anzeigescheibe 2 verbundenen Triebes 9 (Fig. 3). Die Rastfeder 8 kann nach Stillstand der Drehbewegung des Triebes 9 voll in die Lücke des Triebes einfallen und eine Rastposition, die der in Fig. 1 dargestellten entspricht, einnehmen. Durch entsprechende Positionierung des Biegepunktes der Rastfeder 8 bewegt sich dabei der Stift 13 auf einer solchen Kreisbahn, dass er kurz nach Realisierung der Blockierfunktion die Kreisbahn des Steuerelementes 12 wieder verlässt und die nächste Fortschaltung der Anzeigescheibe nicht beeinflusst.Triebes 9 and thus comes in a detent position, which corresponds to the following (and thus incorrect) day, comes another, radially projecting control 12 of the program carrier 4 in function with a pin 13, which protrudes from the locking head 11 of the detent spring 8, and pushes the locking head 11 in the correct day corresponding gap of the drive 9 and thus blocks the rotational movement of the display disc 2 connected to the drive 9 (Fig. Fig. 3 ). The detent spring 8 can come to a standstill of the rotational movement of the drive 9 fully into the gap of the drive and a detent position, the in Fig. 1 represented, take. By appropriate positioning of the bending point of the detent spring 8 while the pin 13 moves on such a circular path that he leaves the circular path of the control element 12 shortly after the realization of the blocking function and does not affect the next indexing of the indicator disc.

Erfindungsgemäß ist eine weitere Rastfeder 14 vorgesehen, deren Rastkopf 15 auf ein mit der Anzeigescheibe 3 verbundenes Trieb mit zehn Zähnen einwirkt, wie dies in Fig. 5 dargestellt ist.According to a further detent spring 14 is provided, the locking head 15 acts on a connected to the display disc 3 drive with ten teeth, as in Fig. 5 is shown.

Der Programmträger 4 trägt einen als Steuerelement axial herausragenden Stift 17, der seinerseits mit einer um die Schwenklagerachse 18 drehbaren Klinke 19 zusammenwirken kann. Die Klinke 19 wird unter Wirkung der angeformten Feder 20 so ausgelenkt, dass deren Spitze außer Eingriff zum Trieb 16 gehalten wird, solange der Stift 17 die Klinke 19 nicht berührt.The program carrier 4 carries a control element axially projecting pin 17, which in turn can cooperate with a pivotable about the pivot bearing axis 18 pawl 19. The pawl 19 is deflected under the action of the molded spring 20 so that the tip is held out of engagement with the drive 16, as long as the pin 17 does not touch the pawl 19.

Beim Umschalten vom 30. über den 31. auf den 01. dreht zunächst die Verzahnung 21 des Programmträgers 4 das Trieb 16 und damit die Einerscheibe um eine Teilung weiter, so dass die Anzeige von 0 auf 1 wechselt. Gleichzeitig läuft der Stift 17 gegen die Klinke 19, schwenkt diese so, dass deren Spitze in die Verzahnung des Triebes 16 eintaucht und die Anzeigescheibe 3 am Durchschleudem hindert (Fig. 6). Bei weiterer Drehung des Programmträgers 4 fällt die Klinke 19 wieder vom Stift 17 ab, deren Spitze geht außer Eingriff zum Trieb 16, und der Programmträger kann den Schritt vom 31. auf den 01. vollziehen, ohne dass sich die Anzeigescheibe 3 bewegt (Fig. 7).When switching from the 30th to the 31st to the 01st initially the teeth 21 of the program carrier 4 rotates the drive 16 and thus the one-disc by one division, so that the display changes from 0 to 1. At the same time, the pin 17 runs against the pawl 19, pivots it so that its tip dips into the toothing of the drive 16 and the display disc 3 prevents it from passing through ( Fig. 6 ). Upon further rotation of the program carrier 4, the pawl 19 falls off again from the pin 17, the tip of which is disengaged from the drive 16, and the program carrier can perform the step from the 31st to the 01st without the display disc 3 moves ( Fig. 7 ).
