Definitions
- the invention relates to a date display of a watch with a ring-shaped, provided with the numbers 1-31 for the date designation of the days of the month, on which the respective day of the month can be indicated by a pointer, the pointer by the clockwork of the watch or by means of a crown is movably drivable along the display scale.
- a clock with a date display which has an annular display scale with the numbers 1 to 31 for the date display. This scale is firmly and immovably connected to the clock's time dial. Another ring enclosing the display scale with the date designations bears the designations of the day of the week and can be rotated relative to the display scale. This means that the corresponding correct weekday name can be assigned to the respective date.
- Such date displays have the disadvantage that it is not possible to have a special desired date, e.g. to indicate the start of the holiday, a birthday or the wedding day and the approaching of this desired date.
- the display scale is arranged on a scale ring, which can be moved in or against the direction of movement of the pointer to position each date in a specific position.
- the display scale can be moved so that the desired date is in a special position. This can be a fixed mark or the 12 o'clock position of an analog clock.

- a more favorable storage is obtained if the adjusting bolt is slidably mounted in a guide sleeve fixedly arranged in the housing opening.
- the adjusting bolt can have a pusher cap on its end protruding from the housing.
- the adjusting bolt is spring-loaded towards the exterior of the housing, it is reset and held in the rest position after actuation.
- a movement of the scale ring can take place in that the scale ring is provided with a spur gear, in whose tooth gaps a tooth of the drive device can be moved.
- the scale ring is moved by the ramp-like sliding of the tooth along a flank of the tooth gap.
- the spur gear preferably has radially outwardly directed teeth, the tooth of the drive device being movable radially towards the spur gear.
- the spur gear has 31 teeth or a number of teeth that is a multiple of 31.
- a simple and space-saving design of the drive device results from the fact that the tooth is arranged at the free end of a lever which can be pivoted about an axis and which is acted upon by a spring in the coupling direction of the tooth from the tooth gaps of the spur gear.
- the tooth can be arranged on the free end of a lever arm of a two-armed lever which can be pivoted about an axis and the second lever arm can be acted upon by a spring in the decoupling direction of the tooth from the tooth gap of the spur gear.
- the lever can arch along in a space-saving manner extend the circumference of the spur gear.
- the spring is the free end of the second lever arm, which is designed as a spring arm and is supported on the housing radially outward under pretension.
- this or the lever arm can be moved by the adjusting bolt in the coupling direction of the tooth in a tooth gap of the spur gear.
- the second lever arm has a holding tooth which can be moved into a tooth gap of the spur gear, then this holding tooth is in a tooth gap in the rest position due to the spring action of the lever and secures the scale ring against automatic adjustment.
- the distance between the tooth and the holding tooth in the circumferential direction of the spur gear is larger or smaller than a whole multiple of the tooth parts and the spur gear.
- the scale ring is moved further in two partial steps when the adjusting bolt is lifted .
- the first sub-step is effected by the tooth engaging in a tooth gap, while the second sub-step is carried out by the subsequent engagement of the holding tooth in a tooth gap.
- the direction of rotation is determined by the fact that the distance between the axis and the tooth is a multiple of the tooth pitch and more than 0.5 times and or less than 0.5 times the tooth pitch.
- the one interacting with the tooth gaps can Tip of the holding tooth have a larger angle than the tooth gaps.
- the tip of the tooth interacting with the tooth gaps has a smaller angle than the tooth gaps.
- the clock shown in Figure 1 is an analog clock with a circular time dial 1, which is enclosed by a scale ring 2 of a date display.
- a display scale 3 with the numbers 1 to 31 is arranged on the scale ring 2.
- the hour hand 5, minute hand 6 and second hand 7 are rotatably arranged on pointer shafts or pointer tubes 4.
- a pointer 8 of the date display is arranged rotatable about the same axis, but on the side of the time dial 1 facing away from an observer. This pointer 8 extends with its free end through an annular gap between time dial 1 and dial ring 2 to the visible side of dial ring 2 and is fork-shaped there. The each The number between the two prongs of the fork is the current date.
- the pointer 8 can also be adjusted via a gear, not shown. A normal advancement of the pointer 8 per day takes place through the clockwork of the clock, also not shown.
- the dial ring 2 with its radially outer circumferential edge 10 is rotatably mounted in a corresponding annular groove 11 of the housing 12 of the watch, which is open toward the dial ring 2.
- a two-armed lever 14 is arranged in a circumferential annular groove 13, which is remote from the observer and is formed and is pivotable about an axis 15 fixed to the housing and parallel to the axis of rotation of the pointer 8.
- the spring 14 acts on the second lever arm 20 radially to the axis of rotation of the pointer 8 and the lever 14 is acted upon from the tooth gaps 18 in the decoupling direction of the tooth 17.
- the spring is the free end of the second lever arm 20, which is designed as a spring arm 21 and is supported on the housing 12 radially outward under prestress.
- the lever arm 16 can be acted upon radially toward the spur gear 19 in the region of the tooth 17 by the one free end of an adjusting bolt 23.
- the adjusting pin 23 is slidably mounted in a guide sleeve 25 which leads radially outwards and is fixedly arranged in a corresponding housing opening 24.
- the adjusting bolt 23 is provided with a cup-shaped push cap 26 which engages over the outwardly directed end of the guide sleeve 25.
- a compression spring 27 arranged under pretension between the presser cap 26 and the guide sleeve 25, the adjusting bolt 23 is held in its radially outer end position when the presser cap 26 is not actuated.
- the free end of the pot-shaped edge of the presser cap 26 engages around a radially outwardly directed peripheral edge 28 of the guide sleeve 25 and thus limits a movement of the adjusting bolt 23 radially outwards.
- a driver 29 Extending into the path of movement of the inward end of the adjusting bolt 23, parallel to the axis 15, is a driver 29 which is firmly connected to the lever arm 16 in the region of the tooth 17 and via which, when the adjusting bolt 23 moves radially inward, the lever 14 until the tooth 17 engages is pivoted in a tooth gap 18.
- the distance between the axis 15 and the tooth 17 is 9 times the tooth pitch of the spur gear 19 plus 1/3 of a tooth pitch, while the distance between the axis 15 and the holding tooth 22 is 6 times the tooth pitch.
- the spring arm 21 moves the retaining tooth 22 from its uncoupling position shown with a broken line into the tooth gap, as a result of which the retaining tooth 22 on a tooth flank slides along the scale ring 2 in a counterclockwise direction until the movement initiated by tooth 17 for adjustment to complete an entire tooth division.
- the number of teeth of the spur gear 12 is twice that of 31 in the exemplary embodiment, so that a double actuation of the lever 14 is required to adjust the scale ring 2 by one day.
- This adjustment allows the scale ring 2 to move into a special position with a certain date, e.g. the 12 o'clock position. Accordingly, the pointer 8 must then be corrected to the current date by means of the crown 9. Now you can always see at a glance the day's distance from the current date to a desired date set in the special position.

Description
Die Erfindung bezieht sich auf eine Datumsanzeige einer Uhr mit einer ringförmigen, mit den Zahlen 1-31 zur Datumsbezeichnung der Monatstage versehenen Anzeigeskala, auf der von einem Zeiger der jeweilige Monatstag anzeigbar ist, wobei der Zeiger durch das Uhrwerk der Uhr bzw. mittels einer Krone entlang der Anzeigeskala bewegbar antreibbar ist.The invention relates to a date display of a watch with a ring-shaped, provided with the numbers 1-31 for the date designation of the days of the month, on which the respective day of the month can be indicated by a pointer, the pointer by the clockwork of the watch or by means of a crown is movably drivable along the display scale.
Bei derartigen Datumsanzeigen bewegt sich ein z.B. um die Zeigerachse der Uhr drehbarer Zeiger entlang der Anzeigeskala, die die Zahlen 1 bis 31 zur Bezeichnung der Monatstage trägt. Durch das Triebwerk der Uhr wird der Zeiger pro Tag zur nächsten Zahl weiterbewegt. Um z.B. nach einem Monat mit 30 Tagen die Datumsanzeige korrigieren zu können, kann der Zeiger auch mittels der Krone verstellt werden.With such date displays, e.g. hands rotatable around the pointer axis of the watch along the display scale, which bears the numbers 1 to 31 to indicate the days of the month. The clock's engine moves the hand to the next number each day. To e.g. after one month with 30 days to be able to correct the date display, the hand can also be adjusted using the crown.
Aus der DE-U-70 11 783 ist eine Uhr mit einer Datumsanzeige bekannt, die eine ringförmige Anzeigeskala mit den Zahlen 1 bis 31 zur Datumsanzeige aufweist. Diese Skala ist fest und unbeweglich mit dem Zeitziffernblatt der Uhr verbunden. Ein weiterer, die Anzeigeskala mit den Datumsbezeichnungen umschließender Ring trägt die Wochentagebezeichnungen und ist relativ zur Anzeigeskala verdrehbar. Damit kann dem jeweiligen Datum die entsprechende richtige Wochentagsbezeichnung zugeordnet werden.From DE-U-70 11 783 a clock with a date display is known, which has an annular display scale with the numbers 1 to 31 for the date display. This scale is firmly and immovably connected to the clock's time dial. Another ring enclosing the display scale with the date designations bears the designations of the day of the week and can be rotated relative to the display scale. This means that the corresponding correct weekday name can be assigned to the respective date.
Derartige Datumsanzeigen haben den Nachteil, daß es nicht möglich ist, ein besonderes Wunschdatum, wie z.B. den Ferienbeginn, einen Geburtstag oder den Hochzeitstag und das Näherkommen dieses Wunschdatums anzuzeigen.Such date displays have the disadvantage that it is not possible to have a special desired date, e.g. to indicate the start of the holiday, a birthday or the wedding day and the approaching of this desired date.
Es ist daher Aufgabe der Erfindung, eine Datumsanzeige nach dem Oberbegriff zu schaffen, die die Anzeige eines besonderen Wunschdatums innerhalb eines Monats ermöglicht.It is therefore an object of the invention to provide a date display according to the preamble, which enables the display of a special desired date within a month.
Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß die Anzeigeskala auf einem Skalenring angeordnet ist, der in bzw. entgegen der Bewegungsrichtung des Zeigers jede Datumsbezeichnung in eine bestimmte Position stellend bewegbar ist.This object is achieved according to the invention in that the display scale is arranged on a scale ring, which can be moved in or against the direction of movement of the pointer to position each date in a specific position.
Bei dieser Datumsanzeige kann die Anzeigeskala so bewegt werden, daß das Wunschdatum sich in einer besonderen Position befindet. Dies kann eine gehäusefeste Markierung oder aber auch die 12-Uhr-Position einer Analoguhr sein.With this date display, the display scale can be moved so that the desired date is in a special position. This can be a fixed mark or the 12 o'clock position of an analog clock.
Es wird aber nicht nur durch Übereinstimmung der Zeigerstellung mit dieser besonderen Position das Erreichen des Wunschdatums angezeigt, sondern auch auf echt analoge Art die Annäherung des momentanen Datums an das Wunschdatum verfolgbar gemacht.Not only is the reaching of the desired date indicated by the position of the pointer corresponding to this particular position, but the approximation of the current date to the desired date is also made traceable in a truly analogous manner.
Vorzugsweise umschließt der Skalenring ein kreisförmiges Zeitziffernblatt der Uhr konzentrisch.Preferably, the dial ring concentrically surrounds a circular time dial of the watch.
Eine einfache Ausbildung ergibt sich, wenn der Skalenring am Gehäuse der Uhr und/oder an einem gehäusefesten Bauteil der Uhr drehbar gelagert ist. Dabei kann der Skalenring mit seinem radial äußeren umlaufenden Rand in eine entsprechend geformte, radial umlaufende, zum Skalenring hin offene Ringnut des Gehäuses und/oder des gehäusefesten Bauteils ragen.A simple design results if the scale ring is rotatably mounted on the housing of the watch and / or on a component of the watch which is fixed to the housing. The radially outer circumferential edge of the scale ring can protrude into a correspondingly shaped, radially circumferential ring groove of the housing and / or of the component fixed to the housing, which is open towards the scale ring.
Der Skalenring kann manuell bewegbar antreibbar sein. Dazu kann auf einfache Weise der Skalenring durch eine, mittels eines zum Skalenring hin bewegbaren Stellbolzens, antreibbare Antriebsvorrichtung bewegbar antreibbar sein, wobei vorzugsweise der Stellbolzen radial zum Skalenring hin bewegbar ist.The scale ring can be driven to be manually movable. For this purpose, the scale ring can be driven in a simple manner by a drive device that can be driven by means of an adjusting bolt that can be moved toward the scale ring, wherein the adjusting bolt can preferably be moved radially toward the scale ring.
Der Stellbolzen kann in einer Gehäuseöffnung verschiebbar gelagert sein und zur manuellen Betätigung mit seinem einen Ende aus dem Gehäuse herausragen.The adjusting bolt can be slidably mounted in a housing opening and protrude from the housing with one end for manual actuation.
Eine günstigere Lagerung ergibt sich, wenn der Stellbolzen in eine in der Gehäuseöffnung fest angeordneten Führungshülse verschiebbar gelagert ist.A more favorable storage is obtained if the adjusting bolt is slidably mounted in a guide sleeve fixedly arranged in the housing opening.
Um eine größere Betätigungsfläche zur Beaufschlagung des Stellbolzens zu erhalten, kann der Stellbolzen an seinem aus dem Gehäuse herausragenden Ende eine Drückerkappe aufweisen.In order to obtain a larger actuating surface for acting on the adjusting bolt, the adjusting bolt can have a pusher cap on its end protruding from the housing.
Ist der Stellbolzen zum Gehäuseäußeren hin federbeaufschlagt, so erfolgt nach einer Betätigung ein Zurückstellen und eine Halterung in der Ruheposition.If the adjusting bolt is spring-loaded towards the exterior of the housing, it is reset and held in the rest position after actuation.
Eine Bewegung des Skalenrings kann dadurch erfolgen, daß der Skalenring mit einem Stirnzahnrad versehen ist, in dessen Zahnlücken ein Zahn der Antriebsvorrichtung hineinbewegbar ist. Durch das rampenartige Entlanggleiten des Zahns an einer Flanke der Zahnlücke wird der Skalenring bewegt.A movement of the scale ring can take place in that the scale ring is provided with a spur gear, in whose tooth gaps a tooth of the drive device can be moved. The scale ring is moved by the ramp-like sliding of the tooth along a flank of the tooth gap.
Vorzugsweise besitzt das Stirnzahnrad radial nach außen gerichtete Zähne, wobei der Zahn der Antriebsvorrichtung radial zum Stirnzahnrad hin bewegbar ist.The spur gear preferably has radially outwardly directed teeth, the tooth of the drive device being movable radially towards the spur gear.
Das Stirnzahnrad besitzt 31 Zähne bzw. eine Anzahl Zähne, die ein ganzes Vielfaches von 31 ist. Je größer das Vielfache von 31 ist, um so geringer und platzsparender kann die Zahntiefe der Zähne des Stirnzahnrades ausgebildet sein. Es muß dann nur ein mehrfaches Hineinbewegen des Zahns in die Zahnlücken des Stirnzahnrades erfolgen.The spur gear has 31 teeth or a number of teeth that is a multiple of 31. The greater the multiple of 31, the smaller and more space-saving the tooth depth of the teeth of the spur gear can be. It is then only necessary to move the tooth several times into the tooth gaps of the spur gear.
Eine einfache und platzsparende Ausbildung der Antriebsvorrichtung ergibt sich dadurch, daß der Zahn an dem freien Ende eines um eine Achse schwenkbaren Hebels angeordnet ist, der durch eine Feder in der Kupplungsrichtung des Zahns aus den Zahnlücken des Stirnzahnrads beaufschlagt ist.A simple and space-saving design of the drive device results from the fact that the tooth is arranged at the free end of a lever which can be pivoted about an axis and which is acted upon by a spring in the coupling direction of the tooth from the tooth gaps of the spur gear.
In einer anderen Ausführungsform kann der Zahn an dem freien Ende eines Hebelarms eines zweiarmigen, um eine Achse schwenkbaren Hebels angeordnet sein und der zweite Hebelarm durch eine Feder in Entkupplungsrichtung des Zahns aus der Zahnlücke des Stirnzahnrades beaufschlagt sein. Der Hebel kann sich dabei in raumsparender Weise bogenförmig entlang des Umfangs des Stirnzahnrades erstrecken.In another embodiment, the tooth can be arranged on the free end of a lever arm of a two-armed lever which can be pivoted about an axis and the second lever arm can be acted upon by a spring in the decoupling direction of the tooth from the tooth gap of the spur gear. The lever can arch along in a space-saving manner extend the circumference of the spur gear.
Ebenfalls raum- und bauteilsparend ist es, wenn die Feder das als Federarm ausgebildete freie Ende des zweiten Hebelarms ist, das radial nach außen unter Vorspannung am Gehäuse abgestützt ist.It is also space- and component-saving if the spring is the free end of the second lever arm, which is designed as a spring arm and is supported on the housing radially outward under pretension.
Zum Schwenken des Hebels kann dieser bzw. der Hebelarm durch den Stellbolzen in Einkupplungsrichtung des Zahn in einer Zahnlücke des Stirnzahnrades bewegbar sein.To pivot the lever, this or the lever arm can be moved by the adjusting bolt in the coupling direction of the tooth in a tooth gap of the spur gear.
Weist der zweite Hebelarm einen Haltezahn auf, der in eine Zahnlücke des Stirnzahnrads bewegbar ist, so befindet sich in der Ruhestellung durch die Federbeaufschlagung des Hebels dieser Haltezahn in einer Zahnlücke und sichert den Skalenring gegen selbsttätiges Verstellen.If the second lever arm has a holding tooth which can be moved into a tooth gap of the spur gear, then this holding tooth is in a tooth gap in the rest position due to the spring action of the lever and secures the scale ring against automatic adjustment.
Um eine einwandfreie Drehbewegung des Skalenringes zu bewirken, ist der Abstand zwischen Zahn und Haltezahn in Umfangsrichtung des Stirnzahnrades größer bzw. kleiner als ein ganzes Vielfaches der Zahnteile und des Stirnzahnrads.In order to bring about a perfect rotational movement of the scale ring, the distance between the tooth and the holding tooth in the circumferential direction of the spur gear is larger or smaller than a whole multiple of the tooth parts and the spur gear.
Beträgt der Abstand zwischen Achse und Zahn ein Vielfaches der Zahnteilung plus mehr bzw. weniger als das 1,5 fache der Zahnteilung und der Abstand zwischen Achse und Haltezahn ein Vielfaches der Zahnteilung, so erfolgt bei einem Hub des Stellbolzens eine Weiterbewegung des Skalenrings in zwei Teilschritten. Der erste Teilschritt wird durch das Eingreifen des Zahns in eine Zahnlücke bewirkt, während der zweite Teilschritt durch das anschließende Eingreifen des Haltezahns in eine Zahnlücke erfolgt. Die Drehrichtung bestimmt sich dadurch, daß der Abstand zwischen Achse und Zahn ein Vielfaches der Zahnteilung und mehr als das 0,5 fache und oder weniger als das 0,5 fache der Zahnteilung ist.If the distance between the axis and the tooth is a multiple of the tooth pitch plus more or less than 1.5 times the tooth pitch and the distance between the axis and the holding tooth is a multiple of the tooth pitch, the scale ring is moved further in two partial steps when the adjusting bolt is lifted . The first sub-step is effected by the tooth engaging in a tooth gap, while the second sub-step is carried out by the subsequent engagement of the holding tooth in a tooth gap. The direction of rotation is determined by the fact that the distance between the axis and the tooth is a multiple of the tooth pitch and more than 0.5 times and or less than 0.5 times the tooth pitch.
Damit der Skalenring sich aufgrund des Spiels des eingerasteten Haltezahns in der Zahnlücke nicht um ein bestimmtes Maß bewegen kann, kann die mit den Zahnlücken zusammenwirkende Spitze des Haltezahns einen größeren Winkel aufweisen als die Zahnlücken.So that the scale ring cannot move by a certain amount due to the play of the latched retaining tooth in the tooth gap, the one interacting with the tooth gaps can Tip of the holding tooth have a larger angle than the tooth gaps.
Insbesondere, wenn durch den Hub des Zahns der größere Verstellweg erzeugt werden soll, ist es vorteilhaft, wenn die mit den Zahnlücken zusammenwirkende Spitze des Zahns einen geringeren Winkel aufweist als die Zahnlücken.In particular, if the larger adjustment path is to be generated by the stroke of the tooth, it is advantageous if the tip of the tooth interacting with the tooth gaps has a smaller angle than the tooth gaps.

Die in Figur 1 dargestellte Uhr ist eine Analoguhr mit einem kreisförmigen Zeitziffernblatt 1, das von einem Skalenring 2 einer Datumsanzeige umschlossen ist. Auf dem Skalenring 2 ist eine Anzeigeskala 3 mit den Zahlen 1 bis 31 angeordnet.The clock shown in Figure 1 is an analog clock with a circular time dial 1, which is enclosed by a
Zentrisch zu dem Zeitziffernblatt 1 und dem Skalenring 2 sind auf Zeigerwellen bzw. Zeigerrohren 4, Stundenzeiger 5, Minutenzeiger 6 und Sekundenzeiger 7 drehbar angeordnet.Centrally to the time dial 1 and the
Um die gleiche Achse drehbar, aber auf der einem Beobachter abgewandten Seite des Zeitziffernblattes 1 ist ein Zeiger 8 der Datumsanzeige angeordnet. Dieser Zeiger 8 erstreckt sich mit seinem freien Ende durch einen Ringspalt zwischen Zeitziffernblatt 1 und Skalenring 2 auf die Sichtseite des Skalenrings 2 und ist dort gabelförmig ausgebildet. Die jeweils zwischen den beiden Zinken der Gabel befindliche Zahl ist das momentane Datum.A
Über eine Krone 9, die auch zur Korrektur der Stunden- und Minutenzeiger 5 und 6 dient, kann über ein nicht dargestelltes Getriebe auch der Zeiger 8 verstellt werden. Ein normales Weiterstellen des Zeigers 8 pro Tag erfolgt durch das ebenfalls nicht dargestellte Uhrwerk der Uhr.Via a
Wie in Figur 2 zu erkennen ist, ist der Skalenring 2 mit seinem radial äußeren umlaufenden Rand 10 in einer entsprechenden, zum Skalenring 2 hin offenen Ringnut 11 des Gehäuses 12 der Uhr drehbar gelagert.As can be seen in FIG. 2, the
In einer, von dem Beobachter abgewandten Seite des Skalenrings 2 ausgebildeten umlaufenden Ringnut 13 ist ein zweiarmiger Hebel 14 angeordnet, der um eine gehäusefeste, zur Drehachse des Zeigers 8 parallele Achse 15 schwenkbar ist.A two-
An dem freien Ende des einen Hebelarms 16 des Hebels 14 ist ein radial zur Drehachse des Zeigers 8 gerichteter Zahn 17 angeordnet, der durch Schwenken des Hebels 14 um die Achse 15 in ebenfalls radial gerichtete Zahnlücken 18 eines mit dem Zahlenring 2 fest verbundenen Stirnzahnrades 19 bewegbar ist.At the free end of the one
Durch am zweiten Hebelarm 20 radial zur Drehachse des Zeigers 8 angreifende Feder ist der Hebel 14 in Entkupplungsrichtung des Zahns 17 aus den Zahnlücken 18 beaufschlagt.The
Bei der in Figur 3 dargestellten Ausführungsform ist die Feder das als Federarm 21 ausgebildete freie Ende des zweiten Hebelarms 20, das radial nach außen unter Vorspannung am Gehäuse 12 abgestützt ist. An dem zweiten Hebelarm 20 ist ein ebenfalls durch Schwenken des Hebels 14 in eine der Zahnlücken 18 bewegbarer Haltezahn 22 angeordnet, der durch den Federarm 21 beaufschlagt, sich normalerweise in einer Zahnlücke 18 befindet und so den Skalenring 2 unbeabsichtigtes Verdrehen sichert.In the embodiment shown in FIG. 3, the spring is the free end of the
Zum Verschwenken des Hebels 14 ist der Hebelarm 16 im Bereich des Zahns 17 durch das eine freie Ende eines Stellbolzens 23 radial zum Stirnzahnrad 19 hin beaufschlagbar. Der Stellbolzen 23 ist in einer radial nach außen führenden, in einer entsprechenden Gehäuseöffnung 24 fest angeordneten Führungshülse 25 verschiebbar gelagert. An seinem anderen, aus dem Gehäuse 12 herausragenden freien Ende ist der Stellbolzen 23 mit einer topfförmig das nach außen gerichtete Ende der Führungshülse 25 übergreifenden Drückerkappe 26 versehen. Durch eine unter Vorspannung zwischen Drückerkappe 26 und Führungshülse 25 angeordnete Druckfeder 27 ist der Stellbolzen 23 bei unbetätigter Drückerkappe 26 in seiner radial äußeren Endstellung gehalten.To pivot the
Das freie Ende des topfförmigen Randes der Drückerkappe 26 umgreift einen radial nach außen gerichteten umlaufenden Rand 28 der Führungshülse 25 und begrenzt so eine Bewegung des Stellbolzens 23 radial nach außen.The free end of the pot-shaped edge of the
In die Bewegungsbahn des nach innen gerichteten Endes des Stellbolzens 23 ragt, parallel zur Achse 15 ein mit dem Hebelarm 16 im Bereich des Zahns 17 fest verbundener Mitnehmer 29 über den bei radialer Einwärtsbewegung des Stellbolzens 23 durch diesen der Hebel 14 bis zum Eingriff des Zahns 17 in einer Zahnlücke 18 verschwenkt wird.Extending into the path of movement of the inward end of the adjusting
Der Abstand zwischen der Achse 15 und dem Zahn 17 beträgt das 9-fache der Zahnteilung des Stirnzahnrads 19 plus 1/3 einer Zahnteilung, während der Abstand zwischen Achse 15 und Haltezahn 22 das 6-fache der Zahnteilung beträgt.The distance between the
Das bewirkt, daß bei einem Hineinbewegen des Zahns 17 in die Zahnlücke 18 der Zahn 17 rampenartig an einer Zahnflanke bis zum Zahngrund entlanggleitet und dabei den Skalenring 2 im Gegenuhrzeigersinn um mehr als eine halbe Zahnteilung bewegt.
