TECHNISCHES GEBIETTECHNICAL AREA

Die vorliegende Erfindung betrifft einen Minutenzähler einer Uhr, insbesondere eines Chronographen, mit einer zentrale Welle, die einen Sekundenzeiger trägt und die mehrere Aufnahmebereiche aufweist, mit einem Zahnrad, das auf der zentralen Welle für einen Antrieb um diese in einem ersten Aufnahmebereich fest verbunden ist, mit einem Nullstellherz, das auf der Zentrale Welle für einen Antrieb um diese in einem zweiten Aufnahmebereich fest befestigt ist, mit einer Auslöseschnecke, die auf der Zentrale Welle für einen Antrieb um diese in einem dritten Aufnahmebereich angeordnet ist und die eine radial umlaufende, rampenartig ansteigende Schaltkurve aufweist, an der unter federnder Vorspannung eine Nase eines um eine Schwenkachse schwenkbaren Minutenschalthebels während der Drehbewegung der Auslöseschnecke entlang gleitet und nach einem sechzig Sekunden entsprechenden Gleitweg den Punkt des grössten Radius überwindend auf den Punkt des geringsten Radius der Auslöseschnecke abfällt, mit einer an dem Minutenschalthebel angeordneten Minutenschaltklinke, durch die ein drehbar gelagertes Minutenzählrad bei Abfall der Nase des Minutenschalthebels auf den Punkt des geringsten Radius der Schaltkurve um einen Minutenschritt weiterschaltbar ist, wobei der Auslösepunkt des Weiterschaltens durch den Minutenschalthebel verstellbar einstellbar ist.The present invention relates to a minute counter of a timepiece, in particular a chronograph, having a central shaft which carries a second hand and which has a plurality of receiving regions, with a toothed wheel which is fixedly connected on the central shaft for driving about it in a first receiving region. with a nulling heart fixedly mounted on the central shaft for driving about it in a second receiving area, with a tripping screw disposed on the central shaft for driving about it in a third receiving area and having a radially encircling ramp-like rising Switching curve on which under the spring bias slides a nose of a pivotable about a pivot axis minute shift lever during the rotation of the trigger screw and after a sixty seconds corresponding Gleitweg the point of the largest radius overcoming the point of the smallest radius of the trigger screw abf falls, with an electrode disposed on the minute shift lever minutes pawl to the point of least radius of the switching curve is indexable by a rotatably mounted minute counting in waste of the nose of the minute shift lever about a minute step, wherein the trip point of the indexing is adjustable adjusted by the minutes lever.

STAND DER TECHNIKSTATE OF THE ART

Ein Minutenzähler einer Uhr mit den Merkmalen des Oberbegriffs des Anspruchs 1 ist aus der EP 1 953 612 bekannt.A minute counter of a clock with the features of the preamble of claim 1 is known from EP 1 953 612 known.

Bei Uhren soll im Moment des Null-Durchgangs des Sekundenzeigers sowohl die Nase des Minutenschalthebels auf den Punkt des geringsten Radius der Auslöseschnecke abfallen, als auch über den Schalthebel und die Schaltklinke das Minutenzählrad um einen Schritt weiter schalten. Aufgrund von Toleranzen bei der Herstellung und Montage ist die Gleichzeitigkeit dieser beiden Funktionen nicht einfach zu erreichen. Bei der EP 1 953 612 ist dafür eine Verstellmöglichkeit mit Hilfe eines Exzenters vorgesehen, bei dem im Minutenzählrad eine Öffnung vorgesehen ist, die den Kopf des Exzenters aufnimmt. Dann greift ein Finger des Exzenters in die Auslöseschnecke ein und gestattet durch Verdrehung des Exzenterkopfes eine Variation der Einstellung des Winkels der Auslöseschnecke zum Zahnrad. Dadurch kann der Winkelpunkt, an dem die Nase des Einstellhebels vom Punkt des grössten Radius auf den des kleinsten Radius herabfällt, eingestellt werden.For clocks at the moment of the zero crossing of the second hand both the nose of the Minute shift lever to the point of the smallest radius of the release screw fall off, as well as on the lever and the pawl, the minute counter by one step further. Due to manufacturing and assembly tolerances, the simultaneity of these two functions is not easy to achieve. In the EP 1 953 612 is an adjustment provided by means of an eccentric, in which the minute counter an opening is provided which receives the head of the eccentric. Then engages a finger of the eccentric in the trigger screw and allows by rotation of the eccentric head, a variation of the adjustment of the angle of the trigger screw to the gear. As a result, the angle at which the nose of the adjusting lever falls from the point of the largest radius to that of the smallest radius can be adjusted.

Bei der Lösung nach dieser Schrift des Standes der Technik ist es nachteilig, dass für den Einsatz des Exzenters das Zahnrad in einer entsprechenden Materialstärke ausgeführt sein muss. Damit geht auf Grund der radialen Ausdehnung des Sekundenrades und des dadurch gegebenen radial fernen Materials ein gewisses Trägheitsmoment einher.In the solution according to this document of the prior art, it is disadvantageous that the gear must be designed in a corresponding material thickness for the use of the eccentric. This is accompanied by a certain moment of inertia due to the radial extent of the second wheel and the resulting radially distant material.

Eine andere ältere Lösung dieses Problems ist aus der DE 198 52 347 bekannt, bei der die Nase des Minutenschalthebels selber in Umfangsrichtung der Schaltkurve einstellbar ist. Hierfür ist ein Exzenter auf dem Minutenschalthebel selber vorgesehen, mit dem die Position der Spitze der Nase einstellbar ist.Another older solution to this problem is from the DE 198 52 347 known, in which the nose of the minute shift lever itself is adjustable in the circumferential direction of the switching curve. For this purpose, an eccentric is provided on the minute shift lever itself, with which the position of the tip of the nose is adjustable.

DARSTELLUNG DER ERFINDUNGPRESENTATION OF THE INVENTION

Weitere Ausführungsformen sind in den abhängigen Ansprüchen angegeben. Ausgehend von diesem Stand der Technik liegt der Erfindung die Aufgabe zugrunde, eine Einstellmöglichkeit für den Minutenzähler einer Uhr anzugeben, die in einfacher Weise diese Justagemöglichkeit gestattet.Further embodiments are given in the dependent claims. Based on this prior art, the present invention seeks to provide an adjustment for the minute counter of a clock, which allows this adjustment in a simple manner.

Erfindungsgemäss wird diese Aufgabe mit den Merkmalen des Anspruchs 1 gelöst.According to the invention this object is achieved with the features of claim 1.

Dadurch, dass das Minutenrad als dünnes Zahnrad zuunterst ausgeführt ist, ist es möglich, die Auslöseschnecke im Presssitz unterhalb des Nullstellherzens anzuordnen, sodass der Kopf des Exzenters in dem in grösserer Materialdicke ausgeführten Nullstellherz eingesetzt ist und der Finger des Exzenters in der ebenfalls in grösserer Materialdicke ausgeführten Auslöseschnecke. Diese beiden Elemente nehmen aber bei der Konstruktion naturgemäss einen geringeren Durchmesser ein, sodass die Einstellung gemäss der vorliegenden Erfindung mit einem geringeren Trägheitsmoment verbunden ist.The fact that the minute wheel is designed as a thin gear at the bottom, it is possible to arrange the trigger screw in a press fit below the zeroing heart, so that the Head of the eccentric is inserted in the executed in greater material thickness Nullstellherz and the finger of the eccentric in the also executed in greater material thickness trimming screw. However, these two elements inherently assume a smaller diameter in the construction, so that the adjustment according to the present invention is associated with a lower moment of inertia.

Vorteilhafterweise ist die der Zahl 6 der äusseren Form entsprechende Auslöseschnecke im Bereich zwischen kleinstem und grösstem Radius mit einer Ausnehmung versehen, die ein Zurückfedern der Nase des Minutenschalthebels gestattet.Advantageously, the number 6 of the external shape corresponding release screw in the region between the smallest and largest radius is provided with a recess which allows springing back of the nose of the minute shift lever.

BESCHREIBUNG BEVORZUGTER AUSFÜHRUNGSFORMENDESCRIPTION OF PREFERRED EMBODIMENTS

Die Figur 1 zeigt eine perspektivische Explosionsansicht eines Ausführungsbeispiel einer Einstellvorrichtung für den Minutenzähler einer Uhr gemäss der Erfindung. Der dargestellte Minutenzähler der Uhr, insbesondere eines Chronographen umfasst eine von einem nicht dargestellten Uhrwerk drehbar antreibbare zentrale Welle 10, auf der drehfest übereinander ein Sekundenrad 20 und ein Nullsternherz 30 angeordnet ist. Weiterhin ist auf den beiden genannten Elementen eine Auslöseschnecke 40 im Presssitz vorgesehen.The FIG. 1 shows an exploded perspective view of an embodiment of a setting device for the minute counter of a clock according to the invention. The illustrated minute counter of the watch, in particular a chronograph, comprises a central shaft 10 which can be driven rotatably by a clock mechanism (not shown), on which a second wheel 20 and a neutral star heart 30 are arranged in a rotationally fixed manner one above the other. Furthermore, a release screw 40 is provided in a press fit on the two elements mentioned.

Ferner weist die Uhr vorteilhafterweise einen in den Zeichnungen nicht dargestellten Sekundenzeiger auf, dessen Zeigerspitze einer ebenfalls nicht dargestellten Sekundenskala folgt. Dabei steht der Sekundenzeiger in einer festen Winkellage mit dem Sekundenrad 20.Furthermore, the clock advantageously has a not shown in the drawings Second hand on whose pointer tip follows a second scale, also not shown. The second hand is in a fixed angular position with the second wheel 20.

Die Auslöseschnecke 40 verfügt an ihrer radial umlaufenden Mantelfläche 41 über eine rampenartig ansteigende Schaltkurve, die von ihrem Punkt mit dem grössten Radius 42 radial auf einen Punkt mit dem geringsten Radius 44 übergeht. Dabei überwindet sie einen V-förmigen Einschnitt 43, der noch im weiteren beschrieben werden wird.The release screw 40 has at its radially circumferential surface 41 via a ramp-like rising switching curve, which passes from its point with the largest radius 42 radially to a point with the smallest radius 44. It overcomes a V-shaped cut 43, which will be described later.

Der nähere Zusammenbau der einzelnen Elemente ist besser aus der Schnittansicht der Fig. 2 erkennbar, die die zusammengebauten Bauteile der Figur 1 zeigt. Zentral auf der Longitudinalachse 100 ist die zentrale Welle 10 dargestellt, die über das mit ihm fix verbundenen Zahnrad 20 angetrieben wird. Das Zahnrad 20 verfügt an seinem äusseren Rand über eine Vielzahl von Zähnen, in die ein nicht weiter dargestellter Antrieb eingreift. Das Zahnrad 20 ruht auf einem Anschlagflansch 11, der über einen ersten Aufnahmebereich 12 hinaus steht, auf dem das Zahnrad 20 mit seinem Befestigungsloch 22 eingesetzt ist. Vorzugsweise wird das Zahnrad 20 mit einer Nietverbindung mit der zentralen Welle 10 verbunden. Üblicherweise ist der Durchmesser des ersten Aufnahmebereiches 12 grösser als eine Abstandsstufe 15, auf welcher das Nullstellherz 30 aufgesetzt ist. Das Nullstellherz 30 ist dabei fix befestigt und dreht sich mit der Welle 10 mit. Es ist so ausgerichtet, dass ein auf die Einstellfläche 54 wirkender Nullstellhebel des Sekundenzeigers diesen auf seiner Skala auf Null setzt. Diese Befestigung des Nullstellherzens 30 ist ohne Toleranz im zweiten Aufnahmebereich 13 realisiert.The closer assembly of the individual elements is better from the sectional view of Fig. 2 recognizable, the assembled components of the FIG. 1 shows. Centrally on the longitudinal axis 100, the central shaft 10 is shown, which is driven via the fixedly connected with him gear 20. The gear 20 has at its outer edge via a plurality of teeth, in which engages a non-illustrated drive. The gear 20 rests on a stop flange 11 which projects beyond a first receiving region 12, on which the gear 20 is inserted with its attachment hole 22. Preferably, the gear 20 is connected to the central shaft 10 with a rivet connection. Usually, the diameter of the first receiving area 12 is greater than a distance step 15, on which the zeroing heart 30 is placed. The zeroing heart 30 is fixedly fixed and rotates with the shaft 10. It is so oriented that a zeroing lever of the second hand acting on the setting surface 54 sets it to zero on its scale. This attachment of the zeroing heart 30 is realized without tolerance in the second receiving area 13.

Der dritte Aufnahmebereich 14 weist wiederum einen geringeren Durchmesser der Welle 10 als der zweite Aufnahmebereich 13 auf, sodass sich eine Stufe bildet, auf welcher die Auslöseschnecke 40 aufgesetzt ist. Die Auslöseschnecke 40 befindet sich dabei in einem Presssitz und ist bei Einwirken einer Kraft gegenüber der Welle 10 drehbar gelagert. In dem Nullstellherz 30 ist ein Exzenterloch 32 vorgesehen, welches in einem Abstand von der Achse 100 der zentralen Welle 10 angeordnet ist, die in der Fig. 2 mit der Achse 110 bezeichnet ist.The third receiving region 14 again has a smaller diameter of the shaft 10 than the second receiving region 13, so that a step is formed, on which the triggering screw 40 is placed. The trigger screw 40 is in a press fit and is rotatably supported by a force against the shaft 10. In the Nullstellherz 30 an eccentric hole 32 is provided, which is arranged at a distance from the axis 100 of the central shaft 10, which in the Fig. 2 designated by the axis 110.

Die Auslöseschnecke 40 selber verfügt über ein Langloch 45, welches radial zu seinem Befestigungsloch 46 verläuft, einen grösseren Durchmesser als das Exzenterloch 32 im Nullstellherz 30 aufweist und in radialer Richtung symmetrisch bezüglich der Drehachse 110 verläuft.The release screw 40 itself has a slot 45 which extends radially to its mounting hole 46, a larger diameter than the eccentric hole 32 in Nullstellherz 30 and in the radial direction is symmetrical with respect to the axis of rotation 110.

In die beiden genannten Löcher 45 und 32 wird ein Exzenter 50 eingesetzt, dessen zylindrischer Finger 52 im wesentlichen passend zum Loch 32 ausgestaltet ist und in dieses eingreift. Der Zylinderkopf 51 des Exzenters 50, der ebenfalls zylindrisch ausgestaltet ist, aber eine andere Symmetrieachse aufweist, ist im Loch 45 eingesetzt. Damit kann durch Drehen des Kopfes 51 des Exzenters 50 über den Betätigungsschlitz 53 erreicht werden, dass sich die Position des Exzenterkopfes 51 in dem Langloch 45 zwischen der in der Figur 2 dargestellten Position (radial äusserste Position) und der entgegen gesetzten Position verändert. Bei dieser Drehung des Exzenters 50 um die Achse 110 verändert sich die Winkeleinstellung der Kurvenscheibe 40 gegenüber dem Nullstellherz 30 und damit gegenüber dem Zahnrad 20.In the two said holes 45 and 32, an eccentric 50 is used, the cylindrical finger 52 is configured substantially matching the hole 32 and engages in this. The cylinder head 51 of the eccentric 50, which is also cylindrical, but has a different axis of symmetry, is inserted in the hole 45. This can be achieved by turning the head 51 of the eccentric 50 via the actuating slot 53 that the position of the eccentric head 51 in the slot 45 between in the FIG. 2 shown position (radially outermost position) and the opposite position changed. During this rotation of the eccentric 50 about the axis 110, the angular adjustment of the cam 40 relative to the zeroing heart 30 and thus relative to the gear 20 changes.

Es ist festzuhalten, dass das radiale Langloch 45 diese Bewegung in grösserem Umfang ermöglicht, da bei einer passgenauen Paarung Loch 32-Finger 52 und Loch (45)-Kopf 51 die Einstellmöglichkeiten sehr limitiert wären, da mit jeder grösseren Drehung des Kopfes 52 des Exzenters 51 auch eine radiale Abstandsänderung des Kopfes 52 in der Auslöseschnecke 40 verbunden ist, da der Finger 52 zu einer solchen Anpassung in dem passgenauen Loch 32 nicht fähig ist.It should be noted that the radial slot 45 allows this movement to a greater extent, since in a snug fit hole 32-finger 52 and hole (45) head 51, the settings would be very limited, as with each major rotation of the head 52 of the eccentric 51 is also connected to a radial change in the distance of the head 52 in the trigger screw 40, since the finger 52 is not capable of such an adjustment in the mating hole 32.

Bei einem in den Zeichnungen nicht dargestellten Ausführungsbeispiel ist das Loch 32 ein radiales Langloch für eine radiale Bewegung des Fingers 52 bei einer Drehbewegung des Exzenters mit einer Winkeleinstellung zwischen Auslöseschnecke 40 und Nullstellherz 30 und das Loch 45 ist ein gerade den Kopf 52 aufnehmendes durchgehendes Rundloch.In one embodiment, not shown in the drawings, the hole 32 is a radial slot for a radial movement of the finger 52 in a rotational movement of the eccentric with an angular adjustment between the trigger screw 40 and zeroing heart 30 and the hole 45 is just the head 52 receiving through round hole.

In beiden Fällen könnte das Loch 32 im Nullstellherz 30 auch ein Sackloch sein.In both cases, the hole 32 in Nullstellherz 30 could also be a blind hole.

Die Fig. 3 zeigt nun eine Draufsicht auf die Einstellvorrichtung gemäss Fig. 1, bei welcher weitere Bauteile des Minutenzählrades dargestellt sind. Insbesondere ist der Klinkenhebel 60 dargestellt, der um eine Achse 62 rotiert, die parallel zur Achse 100 bzw. 110 ist. Der Klinkenhebel 60 verfügt an einem freien Ende über eine Nase 61, die durch die Wirkung der Blattfeder 63 gegen die Schaltkurve 41 der Auslöseschnecke gedrückt wird. Bei einer Drehung des Zahnrades 20 gegen den Uhrzeigersinn läuft die Nase 61 auf der Schaltkurve 41 im wachsenden Abstand von der Achse 100 bis zum Punkt des maximalen Radiusabstandes 42 um dann auf den in der Figur 3 dargestellten Zeitpunkt und Position des geringsten Radiusabstandes 44 zurück zufallen. Zum Zeitpunkt des grössten radialen Abstandes kommt die an einem anderen freien Ende des Hebels 60 gegenüber der Schwenkachse 62 montierte Minutenschaltklinke 71 aus dem Eingriff der Sägezähne 72 des Minutenzählrades 70. Das Minutenzählrad 70 verfügt dabei bei diesem Ausführungsbeispiel über dreissig Sägezähne 72 mit entsprechenden Zahnlücken 73. Bei dem dargestellten Ausführungsbeispiel sind die dreissig Zähne sind nicht alle gleich; die Zahnlücke 73, in welche die Klinke 71 in der Zeichnung eingreift, ist viel tiefer als die anderen. In anderen in den Zeichnungen nicht dargestellten Ausführungsbeispielen können die Zähne 73 auch alle gleich ausgestaltet sein.The Fig. 3 now shows a plan view of the adjustment according to Fig. 1 in which further components of the minute counter are shown. In particular, the latch lever 60 is shown, which rotates about an axis 62 which is parallel to the axis 100 and 110, respectively. The pawl lever 60 has at a free end via a nose 61 which is pressed by the action of the leaf spring 63 against the switching cam 41 of the tripping screw. At a Rotation of the gear 20 counterclockwise runs the nose 61 on the cam 41 in the growing distance from the axis 100 to the point of the maximum radius distance 42 to then on in the FIG. 3 shown time and position of the smallest radius distance 44 fall back. At the time of the greatest radial distance, the minute switching pawl 71 mounted on another free end of the lever 60 with respect to the pivot axis 62 comes out of engagement with the saw teeth 72 of the minute counter 70. In this exemplary embodiment, the minute counter 70 has thirty saw teeth 72 with corresponding tooth gaps 73. In the illustrated embodiment, the thirty teeth are not all the same; the tooth gap 73 in which the pawl 71 engages in the drawing is much deeper than the others. In other embodiments, not shown in the drawings, the teeth 73 may all be configured the same.

Aus der Fig. 1 ist gut erkennbar, dass mit der erfindungsgemässen Lösung das Exzenterrad 50 in zwei in dickerer Materialstärke ausgeführten Bauteilen eingesetzt ist, nämlich dem Nullstellherz 30, auf dem ein in den Figuren nicht dargestellter Hebel im Bereich der Einstellfläche 54 einwirken kann, wenn eine Nullstellung vorgenommen werden soll; und in die Auslöseschnecke 40, in die die ebenfalls etwas dickere Nase 61 des Einstellhebels 60 eingreift. Damit ist es möglich, dass Zahnrad 20 dünn auszuführen und somit die Masse des trägen Systems wirkungsvoll zu reduzieren. Insofern sind die Begriffe dünn und dick wie folgt zu verstehen. Die Materialdicke des Zahnrades 20 ist geringer als die Materialdicke der Auslöseschnecke 40 in axialer Richtung der Welle 10. Die Materialdicke des Zahnrades 20 ist geringer als die Materialdicke des Nullstellherzes 30 in axialer Richtung der Welle 10. Vorteilhafterweise ergeben sich dann ähnliche oder gleiche Materialdicken von Nullstellherz 30 Auslöseschnecke 40. Die Dicke des Einstellhebels 60 in dieser axialen Richtung ist dann vergleichbar, aber nicht grösser als die Dicke der Auslöseschnecke 40.From the Fig. 1 is clearly visible that with the inventive solution, the eccentric wheel 50 is used in two running in thicker material components, namely the Nullstellherz 30 on which a not shown in the figures lever in the adjustment surface 54 can act when a zero position to be made ; and in the trigger screw 40, in which the slightly thicker nose 61 of the adjusting lever 60 engages. Thus, it is possible to make the gear 20 thin and thus effectively reduce the mass of the inertial system. In this respect, the terms thin and thick are to be understood as follows. The material thickness of the gear 20 is less than the material thickness of the trigger screw 40 in the axial direction of the shaft 10. The material thickness of the gear 20 is less than the material thickness of the zeroing heart 30 in the axial direction of the shaft 10. Advantageously, then arise similar or the same material thicknesses of zero heart 30 release screw 40. The thickness of the adjusting lever 60 in this axial direction is then comparable, but not greater than the thickness of the trigger screw 40th

Es hat sich in Versuchen herausgestellt, dass der Presssitz der Auslöseschnecke 40 für die beiden damit verbundenen Funktionen ausreichend ist. Zum einen sitzt die Auslöseschnecke 40 ausreichend sicher auf der zentralen Welle 10 und zum anderen ist es mit Hilfe eines Einsetzens eines Werkzeugs in den Schlitz 53 und der Ausübung einer Kraft für eine Drehung des Exzenterkopfes 51 möglich die Winkelstellung der Auslöseschnecke 40 bezüglich zu Nullstellherz 30 und Zahnrad 20 zu verändern. Dabei gestattet das Langloch 45 je nach Auslegung im Verhältnis vom Durchmesser des Exzenterkopfes 51 zum Durchmesser des Fingers 52 eine Winkelbewegung um einige Grad, beispielsweise zwischen 1 und 10. Grad oder 2 bis 5 Grad.It has been found in experiments that the interference fit of the trigger screw 40 is sufficient for the two functions associated therewith. On the one hand, the tripping screw 40 sits sufficiently securely on the central shaft 10 and, on the other hand, by means of inserting a tool into the slot 53 and exerting a force for rotation of the eccentric head 51, the angular position of the spindle is possible Tripping screw 40 with respect to zeroing heart 30 and gear 20 to change. The slot 45 allows depending on the design in relation to the diameter of the eccentric head 51 to the diameter of the finger 52 an angular movement by a few degrees, for example between 1 and 10 degrees or 2 to 5 degrees.

Vorteilhafterweise ist der Exzenter 50 durch die Anordnung des Loches 32 im Herz 31 so von der Achse 100 entfernt angeordnet; dass er vorzugsweise im Bereich der Hälfte der Schaltkurve 41 mit dem grösseren radialen Abstand von der Mitte vorgesehen ist, also jenseits (in der Zeichnung der Fig. 1 links von) der gedachten radialen Linie zwischen dem Punkt des grössten Radius 41 und dem Punkt des kleinsten Radius 44 über das Zentrum der Welle 10 hinaus zur gegenüberliegenden Seite der Schnecke 41, wo diese Linie über die Spitze 34 des Nullstellherzens 30 verläuft. Dabei liegt das Langloch 45 dann in einem Winkelsegment von 30 Grad zu der Linie Spitze 34

Figure imgb0001
Welle 10, um von dem noch bestehenden grösseren Materialabschnitt des Nullstellherzens 30 nahe der Spitze 34 zu profitieren. Allgemein ist es schon von Vorteil, wenn die Mittelachse 110 der Öffnung 32 in dem Nullstellherz 30 in einem Winkelbereich von -30 und +30 Grad um die gedachte Verbindung zwischen der Drehachse 100 und der Spitze 34 des Nullstellherzens 30 vorgesehen ist.Advantageously, the eccentric 50 is arranged so removed from the axis 100 by the arrangement of the hole 32 in the heart 31; that it is preferably provided in the region of half of the switching cam 41 with the greater radial distance from the center, ie beyond (in the drawing of Fig. 1 to the left of) the imaginary radial line between the point of greatest radius 41 and the point of smallest radius 44 beyond the center of the shaft 10 to the opposite side of the screw 41 where this line passes over the tip 34 of the nulling heart 30. In this case, the slot 45 is then in an angular segment of 30 degrees to the line tip 34th

10 to benefit from the remaining larger material portion of the zeroing heart 30 near the top 34. In general, it is already advantageous if the central axis 110 of the opening 32 in the zeroing heart 30 is provided in an angular range of -30 and +30 degrees about the imaginary connection between the rotation axis 100 and the tip 34 of the zeroing heart 30.

Alternativ kann auch die Öffnung 32 ein Langloch sein und die Öffnung 45 ein passgenaues Loch, so dass die Drehachse des Exzenters, die dann die Achse 110 ersetzt mit der Drehachse des Kopfes 51 übereinstimmt und der Finger 52 sich in einem Langloch bewegt. Das hier beschriebene Ausführungsbeispiel hat aber den Vorteil, dass, wie in der Fig. 3 gut zu erkennen ist, ein Teil des Exzenterkopfes 51 im Langloch 45 radial ausserhalb der Schaltkurve 31 des Nullstellherzens 30 ist, so dass der Abstand der beiden Drehachsen 100 und 110 voneinander, die ja beide die Übersetzung festlegen, möglichst gross wird.Alternatively, the opening 32 may be a slot and the opening 45 a hole exactly fitting, so that the axis of rotation of the eccentric, which then replaces the axis 110 with the axis of rotation of the head 51 and the finger 52 moves in a slot. The embodiment described here has the advantage that, as in the Fig. 3 It can be seen well, a portion of the eccentric head 51 in the slot 45 radially outside the switching curve 31 of the zeroing heart 30, so that the distance between the two axes of rotation 100 and 110 from each other, both set the translation as large as possible.

Bei dem dargestellten Ausführungsbeispiel ist in Richtung der Längsachse der Welle 10 die Reihenfolge der Elemente Auslösekurve-Nullstellherz-Sekundenrad. In einem in den Zeichnungen nicht dargestellten Ausführungsbeispiel ist die Reihenfolge Nullstellherz-Auslösekurve-Sekundenrad, wo also die beiden oberen dickeren Elemente in umgekehrter Reihenfolge vorgesehen sind, was auf Grund der funktionalen Einstellung von Langloch 45 und Loch 32 möglich ist. Bei einem weiteren Ausführungsbeispiel ist das Sekundenrad 20 mit mindestens einem Durchbruch für den Exzenterkopf versehen, so dass es auch (im Hinblick auf die Zeichnung der Fig. 3) "oben" sein kann, also die Reihenfolge Sekundenrad-Auslösekurve-Nullstellherz ist. Dann ist der Exzenterkopf 51 in einem solchen Durchbruch angeordnet und wirkt von dort in die in der Fig. 3 dargestellte, dann aber unter dem Sekundenrad 20 angeordnete Auslösekurve 40 und Nullstellherz 30.
