Ein derartiger Chronograph ist aus der DE 42 09 580 C2 bekannt. Bei diesem bekannten Chronographen können nach einem Start durch Betätigung des ersten Stellelements der Chronographenzeiger und der Rattrapantezeiger gemeinsam wieder angehalten werden. Es kann auch mit dem zweiten Stellelement nur der Rattrapantzeiger angehalten werden, während der Chronographenzeiger weiter läuft. So können Zwischenzeiten innerhalb einer Minute gemessen werden. Wird das zweite Stellelement nochmals betätigt, springt der Rattrapantezeiger auf die Position des laufenden Chronographenzeigers und läuft gemeinsam mit ihm weiter und ist zu einer erneuten Messung für eine weitere Zwischenzeit bereit. Die Messung von Zwischenzeiten läßt sich beliebig oft wiederholen. Will man auch den Chronographenzeiger anhalten, muß wieder das erste Stellelement betätigt werden. Es gibt also zwei Zustände der stehenden Zeiger. Entweder stehen beide Zeiger übereinander oder jeder Zeiger hat eine eigene Position.Such a chronograph is known from DE 42 09 580 C2. at This known chronograph can after a start by pressing the first actuator of the chronograph hand and the Rattrapante pointer to be stopped together again. It can also stopped with the second actuator only the Rattrapantzeiger while the chronograph hand continues to run. So can Intermediate times are measured within a minute. Will that be pressed again second control element, the rattrapante pointer jumps to the position of the current chronograph hand and runs together Continue with it and re-measure for one another intermediate time ready. The measurement of split times can be Repeat as often as you like. If you also want to stop the chronograph hand, must again be operated the first actuator. So there is two states of the standing hands. Either both hands are pointing one above the other or each pointer has its own position.

Aus der CH 682 201 A ist ein Chronograph mit einem Chronographenzeiger und einem Rattrapantezeiger bekannt. Durch einen ersten Drücker kann der Chronographenzeiger gestartet und durch einen weiteren Drücker in die Nullstellung zurückgestellt werden. Durch einen dritten Drücker kann der Rattrapantezeiger angehalten werden.
Aufgabe der Erfindung ist es einen Chronograph der eingangs genannten Art zu schaffen, bei dem mit einfacher Betätigung aus der Position von übereinander stehenden Chronographenzeiger und Rattrapantezeiger, aus jeweils eigener stehender Position dieser beiden Zeiger und aus dem laufenden Zustand dieser Zeiger jeweils ein augenblickliches Nullstellen sowie beim Nullstellen aus dem laufenden Zustand auch ein augenblicklicher Neustart (Flyback) möglich ist.
The CH 682 201 A is a chronograph with a chronograph hand and a rattrapante pointer known. By a first pusher, the chronograph hand can be started and reset by a further pusher in the zero position. A third pusher can stop the rattrapante pointer.
The object of the invention is to provide a chronograph of the type mentioned, in which with simple operation from the position of superimposed chronograph hands and Rattrapantezeiger, each own standing position of these two hands and from the current state of these pointers each have an instant zero and Zeroing from the current state, an instantaneous restart (flyback) is possible.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß mit einem dritten Stellelement durch dessen manuelle Bewegung aus seiner Nichtbeaufschlagungsstellung in seine Beaufschlagungsstellung Zeigerwelle und Chronographenzeiger in ihre Nullstellung bewegbar sind und das in seiner Blockierstellung befindliche Schaltelement in seine Entblockierstellung bewegbar ist oder das in seiner Entblockierstellung befindliche Schaltelement in seiner Entblockierstellung verbleibt, wobei von dem dritten Stellelement eine Verstelleinrichtung betätigbar ist, durch die das Schaltelement zwischen seiner Blockierstellung und seiner Entblockierstellung bewegbar antreibbar ist und wobei durch ein Abtastelement die Stellung des Schaltelements abtastbar und bei Entblockierstellung des Schaltelements die Verstelleinrichtung inaktivierbar und bei Blockierstellung des Schalt elements die Verstelleinrichtung aktivierbar ist. This object is achieved in that are movable with a third actuator by its manual movement from its Nichtbeaufschlagungsstellung in its Beaufschlagungsstellung pointer shaft and chronograph hand in its neutral position and located in its blocking position switching element is movable into its Entblockierstellung or located in its Entblockierstellung switching element in its Entblockierstellung remains, wherein from the third actuator an adjusting device is actuated, by which the switching element between its blocking position and Entblockierstellung is movable driven and being scanned by a scanning element, the position of the switching element and in Entblockierstellung the switching element, the adjusting inactivated and in blocking position of the switching elements the adjusting device is activated.

Damit wird ein einfacher Aufbau mit einer Mehrfachfunktion erreicht.This achieves a simple structure with a multiple function.

Durch die alleinige einmalige Betätigung des dritten Stellelements sind die stehenden oder laufenden Zeiger in ihre Nullposition stellbar, ohne daß dazu jeweils eine Stellelementbetätigung zum Anhalten, dann zum Nullstellen und ggf. ein drittes Mal zum Neustarten erfolgen muß. Für diesen Neustart ist nur ein Loslassen des betätigten dritten Stellelements erforderlich, so daß dieser Neustart verzögerungsfrei nach dem Nullstellen erfolgen kann.By the sole one-time operation of the third control element the standing or moving hands can be set to their zero position without that in each case one actuator actuation to stop, then to Zeroing and possibly a third time must be done to restart. For This restart is only a release of the actuated third control element required, so that this restart without delay after the Zeroing can be done.

Die Verstelleinrichtung kann ein koaxial drehfest mit dem Schaltelement verbundenes oder über ein Zwischengetriebe drehbar antreibbares Schaltrad aufweisen, das durch eine von dem dritten Stellelement betätigbare Schaltnase um einen Schaltschritt weiterschaltbar ist, der einem Schaltschritt des Schaltelements von der Blockierstellung in die Entblockierstellung entspricht. The adjusting device may have a coaxially non-rotatably connected to the switching element or rotatably driven via an intermediate gear ratchet, which is weiterschaltbar by an operable by the third actuator switching lug to a switching step corresponding to a switching step of the switching element of the blocking position in the Entblockierstellung.

Der in Figur 5 dargestellte Chronograph besitzt ein Uhrgehäuse mit einem runden Zifferblatt 41. Zentrisch ist eine erste Chronographen-Zeigerwelle 28 und eine erste Rattrapante-Zeigerwelle 5 eines Sekundenzählers angeordnet, wobei die erste Chronographen-Zeigerwelle 28 einen Chronographenzeiger 47 und die erste Rattrapante-Zeigerwelle 5 einen ersten Rattrapantezeiger 48 trägt, die einander überdeckend antreibbar sind. The chronograph shown in Figure 5 has a watch case with a round dial 41. Centric is a first chronograph hand wave 28 and a first rattrapante pointer shaft 5 of a second counter, wherein the first chronograph hand shaft 28 is a chronograph hand 47 and the first rattrapante pointer shaft 5 a first Rattrapante pointer 48 carries, which are drivable overlapping each other.

Parallel im Abstand zur ersten Chronographen-Zeigerwelle 28 ist eine zweite Zeigerwelle 51 eines Minutenzählers mit einem zweiten Chronographenzeiger 49 und eine zweite Rattrapante-Zeigerwelle 27 eines mit dem zweiten Chronographenzeiger 49 überdeckend antreibbaren zweiten Rattrapantezeigers 50 angeordnet.Parallel at a distance from the first chronograph hand shaft 28 is a second hand shaft 51 of a minute counter with a second chronograph hand 49 and a second rattrapante pointer shaft 27 with a the second chronograph hand 49 overlapping drivable second Rattrapante pointer 50 arranged.

Eine Krone 42 befindet sich am Uhrgehäuse 40 in der Drei-Uhr Position.A crown 42 is located on the watch case 40 in the three o'clock position.

Weiterhin befinden sich als Drücker ausgebildet ein erstes Stellelement 44 in der Zwei-Uhr-Position, ein zweites Stellelement 46 in der Zehn-Uhr-Position und ein drittes Stellelement 45 in der Vier-Uhr-Position.Furthermore, there are formed as a pusher, a first actuator 44th in the two o'clock position, a second actuator 46 in the ten o'clock position and a third actuator 45 in the four o'clock position.

Wie in den Figuren 7 bis 10 zu sehen ist, ist auf der rohrartigen ersten Chronographen-Zeigerwelle 28 mit dem ersten Chronographenzeiger 47 ein Chronozentrumsrad 34 fest angeordnet, das durch einen Chronographenantrieb 33 drehbar antreibbar ist.As can be seen in Figures 7 to 10 is on the tubular first Chronograph hand shaft 28 with the first chronograph hand 47 a Chronozentrumsrad 34 fixedly arranged by a chronograph drive 33 is rotatably driven.

Auf der ersten Chronographen-Zeigerwelle 28 sind weiterhin ein Sekundenherz 29 zum Zurückstellen des ersten Chronographenzeigers 47 in eine Ausgangs- oder Nullstellung sowie ein Rattrapanteherz 30 einer kraftschlüssigen Kupplung drehfest angeordnet. On the first chronograph hand wave 28 are still a second heart 29 for returning the first chronograph hand 47 in one Initial or zero position and a Rattrapanteherz 30 a non-positive Coupling rotatably arranged.

In der axial durchgehenden Bohrung der rohrartigen ersten Chronographen-Zeigerwelle 28 ist die erste Rattrapante-Zeigerwelle 5 drehbar gelagert. Diese erste Rattrapante-Zeigerwelle 5 trägt drehfest ein Rattrapanterad 6, dessen radial umlaufende Mantelfläche 32 mit einer feinen Verzahnung bzw. Aufrauhung versehen ist.In the axially continuous bore of the tubular first chronograph hand shaft 28, the first rattrapante pointer shaft 5 is rotatable stored. This first rattrapante pointer shaft 5 rotatably carries a rattrapanterad 6, whose radially encircling lateral surface 32 with a fine Gearing or roughening is provided.

Im radial äußeren Bereich des Rattrapanterads 6 ist mit seinem einen Ende ein Rattrapanteherzhebel 35 um eine zur ersten Chronographen-Zeigerwelle 28 parallele Achse 36 schwenkbar angelenkt. Dieser Rattrapanteherzhebel 35 ist in der selben Ebene schwenkbar, in der sich das Rattrapanteherz 30 befindet. Durch eine Zugfeder 37 wird das freie Ende des Rattrapanteherzhebels 35 mit einer Kupplungsfläche 38 in Anlage gegen die umlaufende Mantelfläche 32 des Rattrapanteherzens 30 beaufschlagt.In the radially outer region of the Rattrapanterads 6 is with its one end a rattrapante heart lever 35 about one to the first chronograph hand wave 28 parallel axis 36 pivoted articulated. This rattrapante heart lever 35 is pivotable in the same plane in which the Rattrapanteherz 30 is located. By a tension spring 37, the free end of the Rattrapanteherzhebels 35 with a coupling surface 38 in abutment against the circumferential outer surface 32 of the Rattrapanteherzens 30 applied.

Ist das Rattrapanterad 6 frei drehbar, so gleitet der Rattrapanteherzhebel 35 entlang der Mantelfläche des Rattrapanteherzens 30 bis zu deren der ersten Chronographen-Zeigerwelle 28 nächsten Stellung und kuppelt in dieser Position Rattrapanterad 6 und erste Chronographen-Zeigerwelle 28 kraftschlüssig miteinander.If the rattrapanterad 6 rotates freely, then the rattrapante heart lever slides 35 along the lateral surface of the Rattrapanteherzens 30 up to the first chronograph hand shaft 28 next position and engages in this position rattrapanterad 6 and first chronograph hand shaft 28 non-positively with each other.

In dieser in Figur 9 dargestellten Position befinden sich der erste Chronographenzeiger 47 und der erste Rattrapantezeiger 48 in einer sich einander überdeckenden Stellung. Bei einem Drehantrieb der ersten Chronographen-Zeigerwelle 28 wird über die kraftschlüssige Kupplung des Rattrapanteherzhebels 35 die Rattrapante-Zeigerwelle 5 synchron mitgedreht, so daß sich der erste Chronographenzeiger 47 und der erste Rattrapantezeiger 48 wie miteinander verbunden zusammen bewegen.In this position shown in Figure 9, there are the first chronograph hand 47 and the first Rattrapante pointer 48 in a mutually covering position. In a rotary drive of the first chronograph pointer shaft 28 is via the frictional coupling of the Rattrapanteherzhebels 35 the rattrapante pointer shaft 5 synchronously rotated, so that the first chronograph hand 47 and the first Rattrapante pointer 48 moving together as if connected together.

Wird während des Antriebs der ersten Chronographen-Zeigerwelle 28 das Rattrapanterad 6 blockiert, gleitet unter Spannen der Zugfeder 37 der Rattrapanteherzhebel 35 mit seiner Kupplungsfläche 38 an der Mantelfläche des Rattrapanteherzens 30 entlang, so daß der erste Rattrapantezeiger 48 stehen bleibt, während sich der erste Chronographenzeiger 47 weiter dreht. Dies ist in Figur 10 zu sehen. Bei der Aufhebung der Blockade des Rattrapanterads 6 gleitet der Rattrapanteherzhebel 35 entlang der Mantelfläche des Rattrapanteherzens 30 bis zu dessen der ersten Chronographen-Zeigerwelle 28 nächster Stellung, um sich dann synchron mit der ersten Chronographen-Zeigerwelle 28 weiter zu drehen.During the drive of the first chronograph hand shaft 28, the Rattrapanterad 6 blocks, slides under tensioning the tension spring 37 of the Rattrapanteherzhebel 35 with its coupling surface 38 on the lateral surface of the rattrapante heart 30 so that the first rattrapante hand 48 stops while the first chronograph hand 47 continues rotates. This can be seen in FIG. In lifting the blockade of the Rattrapanterads 6 slides the Rattrapanteherzhebel 35 along the lateral surface Rattrapante heart 30 up to the first chronograph hand wave 28 next position, in order to synchronize with the continue to rotate first chronograph hand shaft 28.

Zum Blockieren der Drehbewegung des Rattrapanterads 6 wird dieses von den freien Enden der Zangenarme 1, 1' einer etwa u-förmig angeordneten ersten Rattrapantezange 31 umgriffen. An den der Mantelfläche 32 des Rattrapanterads 6 zugewandten Flächen sind die Zangenarme 1, 1' ebenfalls mit einer feinen Verzahnung bzw. Aufrauhung versehen, so daß eine formschlüssige Verbindung zwischen dem Rattrapanterad 6 und den Zangenarmen 1, 1' herstellbar ist.To block the rotational movement of the Rattrapanterads 6 this is from the free ends of the gun arms 1, 1 'arranged approximately U-shaped first rattrapante forceps 31 embraced. At the lateral surface 32 of the Rattrapanterads 6 facing surfaces are the pliers arms 1, 1 'also provided with a fine toothing or roughening, so that a positive connection between the Rattrapanterad 6 and the gun arms 1, 1 'can be produced.

An ihren dem Rattrapanterad 6 abgewandten Endbereichen sind die Zangenarme 1, 1' mit einem Befestigungsfuß 4, 4' zur ortsfesten Befestigung versehen.At their the Rattrapanterad 6 remote end portions are the gun arms 1, 1 'with a mounting foot 4, 4' for fixed attachment Mistake.

In dem an den Befestigungsfuß 4, 4' anschließenden Bereich sind die Zangenarme 1, 1' derart als federnder Teil 3 ausgebildet, daß die erste Rattrapantezange 31 unter federnder Vorspannung ihrer Zangenarme 1, 1' gegen das Rattrapanterad 6 steht.In the adjoining the mounting foot 4, 4 'area are the Pliers arms 1, 1 'designed as a resilient part 3, that the first Rattrapantezange 31 under resilient bias of their gun arms 1, 1 'against the Rattrapanterad 6 stands.

Auf der dem Befestigungsfuß 4, 4' abgewandten Seite des federnden Teils 3 sind an den einander zugewandten Innenseiten der Zangenarme 1, 1' V-förmige, rampenartig hervorstehende Abtastnocken 2, 2' ausgebildet.On the side facing away from the mounting foot 4, 4 'of the resilient member 3 are on the mutually facing inner sides of the gun arms 1, 1 'V-shaped, ramp-like protruding Abtastnocken 2, 2 'is formed.

Um eine die Symmetrielinie der ersten Rattrapantezange 31 parallel zur ersten Chronographen-Zeigerwelle 28 schneidende Drehachse ist ein Kolonnenrad 7 drehbar angeordnet, das gleichmäßig am Umfang verteilt vier abwechselnd radial hervorstehende Kolonnen a, b, c, d und vier Täler e, f, g, h geringerer radialer Erstreckung besitzt, wobei die Abtastnocken 2, 2' je nach Stellung des Kolonnenrades 7 auf der Stirnseite einer Kolonne a, b, c, d zur Anlage gelangen und die Zangenarme 1, 1' von dem Rattrapanterad 6 abheben oder in ein Tal e, f, g, h ragen, so daß die Zangenarme 1, 1' unter Federvorspannung an dem Rattrapanterad 6 anliegen und dieses blockieren.To a symmetry line of the first Rattrapantezange 31 parallel to first chronograph hand shaft 28 cutting axis of rotation is a column wheel 7 rotatably arranged, the evenly distributed around the circumference four alternately radially protruding columns a, b, c, d and four valleys e, f, g, h has a smaller radial extent, the Abtastnocken 2, 2 ' depending on the position of the column wheel 7 on the front side of a column a, b, c, d come to rest and the pliers arms 1, 1 'of the rattrapanterad 6 or in a valley e, f, g, h protrude, so that the pliers arms 1, 1 'spring-loaded on the Rattrapanterad 6 and this To block.

Ein Weiterdrehen eines Sägezahnrades 18 um einen 45°-Schritt im Uhrzeigersinn für das Erfassen von Zwischenzeiten erfolgt auf nicht dargestellte Weise durch ein Betätigen des zweiten Stellelements 46, so daß ein solcher Schaltschritt entweder zu einem Entblockieren des vorher blockierten Rattrapanterads 6 oder zu einem Blockieren des vorher entblockierten Rattrapanterads 6 führt.Further rotation of a sawtooth 18 by a 45 ° -step in a clockwise direction for the recording of split times takes place on not shown Way by operating the second actuator 46, so that a such switching step either to unblock the previously blocked Rattrapanterads 6 or to block the previously unblocked Rattrapanterads 6 leads.

Entweder koaxial drehfest mit dem Kolonnenrad 7 verbunden, (Figuren 1 bis 4) oder über ein Zwischengetriebe 43 mit dem Kolonnenrad verbunden (Figur 6) ist das Sägezahnrad 18 mit acht Zähnen Z 1 bis Z 8 angeordnet, das auch durch eine Verstelleinrichtung mittels des dritten Stellelements 45 um einen Schaltschritt von 45° im Uhrzeigersinn weiter drehbar ist.Either coaxially rotatably connected to the column wheel 7, (FIGS to 4) or via an intermediate gear 43 connected to the column wheel (Figure 6) the sawtooth 18 is arranged with eight teeth Z 1 to Z 8, also by an adjustment by means of the third control element 45 is further rotatable by a switching step of 45 ° clockwise.

Die Verstelleinrichtung weist einen um eine zu den Drehachsen des Kolonnenrads 7 und des Sägezahnrads 18 parallele Schwenkachse 22 schwenkbaren und durch das dritte Stellelement 45 in Richtung seiner Längserstreckung etwa tangential zum Zägezahnrad 18 bewegbaren Hebel 19 auf, der an seinem freien Ende eine Schaltklinke 24 besitzt.The adjusting device has a to one of the axes of rotation of the column wheel 7 and the sawtooth 18 parallel pivot axis 22nd pivotable and by the third actuator 45 in the direction of his Longitudinal extension approximately tangentially to the Zägezahnrad 18 movable lever 19, which has a pawl 24 at its free end.

Der Hebel 19 besitzt weiterhin ein Abtastelement 23, das radial am Kolonnenrad 7 anliegt und von diesem radial bewegbar ist. Je nach der Stellung des Kolonnenrads 7 gelangt das Abtastelement 23 auf der Stirnseite einer Kolonne a, b, c, d zur Anlage oder ragt in ein Tal e, f, g, h.The lever 19 further has a sensing element 23, which is radially on the column wheel 7 abuts and is radially movable from this. Depending on the position of the column wheel 7, the scanning element 23 on the front side of a Column a, b, c, d to plant or projects into a valley e, f, g, h.

Entsprechend erfolgt auch ein Verschwenken des Hebels 19 um die Schwenkachse 22 an dem der Schaltklinke 24 entgegengesetzten Ende des Hebels 19.Accordingly, a pivoting of the lever 19 takes place around the Pivot axis 22 at the pawl 24 opposite end of the lever 19.

An der Schwenkachse 22 ist weiterhin ein weiterer Hebel 20 mit seinem einen Ende angelenkt, der sich etwa rechtwinklig zum Hebel 19 erstreckt und an seinem anderen Ende um eine ortsfeste Schwenkachse 21 schwenkbar ist.On the pivot axis 22 is still a further lever 20 with his hinged an end which extends approximately at right angles to the lever 19 and at its other end about a stationary pivot axis 21 is pivotable.

Der Hebel 20 ist durch das dritte Stellelement 45 entgegen einer Federkraft quer zu seiner Längserstreckung beaufschlagbar, so daß er um die Schwenkachse 21 schwenkt und den Hebel 19 etwa in Richtung von dessen Längserstreckung bewegt. The lever 20 is opposed by the third actuator 45 against a spring force transversely acted upon to its longitudinal extent, so that it around the Pivot axis 21 pivots and the lever 19 approximately in the direction of the Lengthwise extension moves.

Befindet sich dabei das Abtastelement 23 auf der Stirnseite einer Kolonne a, b, c, d, so ist dadurch der Hebel 19 derart verschwenkt, daß sich die Schaltklinke 24 außer dem Eingriffsbereich des Sägezahnrads 18 befindet und dieses nicht weiterdrehend beaufschlagen kann.If the scanning element 23 is located on the end face of a column a, b, c, d, then the lever 19 is pivoted in such a way that the Ratchet 24 except the engagement portion of the Sägezahnrads 18 is located and this can not apply further.

Damit verbleibt auch das Kolonnenrad 7 in seiner Stellung, in der die Zangenarme 1, 1' vom Rattrapanterad 6 abgehoben sind und mit diesem Rattrapanterad 6 sich der davon antreibbare erste Rattrapantezeiger 48 zusammen mit dem ersten Chronographenzeiger 47 bewegen kann, nachdem durch die Betätigung des dritten Stellelements 45 beide Zeiger 47 und 48 in die Nullstellung gebracht und die Beaufschlagung des dritten Stellelements 45 beendet worden ist.Thus, the column wheel 7 remains in its position in which the pliers arms 1, 1 'are lifted off the Rattrapanterad 6 and with this Rattrapanterad 6, the first Rattrapantezeiger 48 driven by it together with the first chronograph hand 47 can move after by the operation of the third control element 45 both hands 47th and 48 brought to the zero position and the admission of the third Stellelements 45 has been completed.

Befindet sich, wie in den Figuren 3 und 4 dargestellt, bei der Betätigung des dritten Stellelements 45 das Abtastelement 23 aber in einem Tal e, f. g, h des Kolonnenrads 7, so ist der Hebel 19 mit seiner Schaltklinke 24 in den Eingriffsbereich des Sägezahnrads 18 geschwenkt und dreht durch die Betätigung des dritten Stellelements 45 und die Axialbewegung des Hebels 19 das Sägezahnrad 18 um 45° weiter.Is, as shown in Figures 3 and 4, in the operation of the third control element 45 but the scanning element 23 in a valley e, f. g, h of the column wheel 7, then the lever 19 with its pawl 24 in pivots the engagement portion of the Sägezahnrads 18 and rotates through the actuation of the third actuating element 45 and the axial movement of the Levers 19, the saw gear 18 by 45 °.

Damit wird aber auch das Kolonnenrad 7 um 45° weitergedreht, so daß die Abtastnocken 2, 2' auf die Stirnseiten der Kolonnen a, b, c, d gelangen und die vorher geschlossene erste Rattrapantezange 31 mit ihren Zangenarmen 1, 1' abhebt und das Rattrapanterad 6 drehblockiert. Damit springt der erste Rattrapantezeiger 48 auf die Position des Chronographenzeigers 47.But also the column wheel 7 is further rotated by 45 °, so that the Abtastnocken 2, 2 'on the end faces of the columns a, b, c, d arrive and the previously closed first Rattrapantezange 31 with their Pliers arms 1, 1 'lifts and the Rattrapanterad 6 rotatably blocked. In order to the first rattrapante pointer 48 jumps to the position of the chronograph hand 47th

Damit ein unbeabsichtigtes Schalten des Sägezahnrades 18 verhindert wird, ist eine Rastfeder 25 vorgesehen, die in die Zahnlücken e, f, g, h des Sägezahnrades 18 federnd einrastbar ist.This prevents inadvertent switching of the sawtooth 18 is, a detent spring 25 is provided which in the tooth gaps e, f, g, h of the Sawtooth 18 resiliently latched.

Durch den Chronographenantrieb 33 ist bei manueller Betätigung des ersten Stellelements 44 auch die zweite Zeigerwelle 51 des zweiten Chronographenzeigers 49 drehbar antreibbar, zu der die zweite Rattrapante-Zeigerwelle 27 des zweiten Chronographenzeigers 49 koaxial angeordnet ist, der mit dem zweiten Rattrapantezeiger 50 überdeckend antreibbar ist.By the chronograph drive 33 is manual operation of the first Actuator 44 and the second pointer shaft 51 of the second chronograph hand 49 rotatably driven, to which the second Rattrapante pointer shaft 27 of the second chronograph hand 49 coaxially arranged is, which is drivable overlapping with the second Rattrapantezeiger 50.

Auf gleiche, aber nicht dargestellte Weise, wie für den Antrieb von erstem Chronographenzeigers 47 und ersten Rattrapantezeiger 48 und mit gleicher Funktionsweise ist auf der zweiten Zeigerwelle 51 ein Minutenzählerherz zum Zurückstellen des zweiten Chronographenzeigers 49 angeordnet und die zweite Zeigerwelle 51 und die zweite Rattrapante-Zeigerwelle 27 sind durch ein zweites Rattrapanteherz einer kraftschlüssigen Kupplung drehfest miteinander verbindbar. In the same way, but not shown, as for the drive of the former Chronograph hand 47 and first Rattrapantezeiger 48 and with the same Operation is on the second pointer shaft 51 a minute counter heart arranged to reset the second chronograph hand 49 and the second pointer shaft 51 and the second rattrapante pointer shaft 27 are by a second Rattrapanteherz a frictional clutch rotatably connected to each other.

Auf der zweiten Rattrapante-Zeigerwelle 27 ist ein zweites Rattrapanterad 26 angeordnet, das von Zangenarmen 12, 12' einer zweiten Rattrapantezange 39 unter Federvorspannung umgreifbar und durch Reibschluß drehblockierbar ist.On the second rattrapante pointer shaft 27 is a second rattrapanterad 26 arranged by the forceps arms 12, 12 'of a second Rattrapantezange 39 with spring preload encompassable and by friction is drehblockierbar.

Die zweite Rattrapantezange 39 besitzt mit den Zangenarmen 12 und 12', mit Abtastnocken 13 und 13', federnden Teilen 14 und 14' sowie Befestigungsfüßen 15 und 15' den gleichen Aufbau und die gleiche Funktionsweise wie die erste Rattrapantezange 31.The second rattrapante forceps 39 has with the forceps arms 12 and 12 ', with Abtastnocken 13 and 13 ', resilient parts 14 and 14' and mounting feet 15 and 15 'the same structure and the same operation like the first rattrapante forceps 31.

Zur Beaufschlagung der Abtastnocken 13, 13' ist zwischen diesen ein etwa in Längserstreckungsrichtung der Zangenarme 12, 12' bewegbares Rampenelement 16 angeordnet, durch das die Zangenarme 12, 12' der zweiten Rattrapantezange 39 voneinander weg spreizbar und somit von dem Rattrapanterad 26 abhebbar sind.To act on the Abtastnocken 13, 13 'is between these an approximately in the longitudinal direction of the forceps arms 12, 12 'movable Ramp element 16 is arranged, through which the pliers arms 12, 12 'of the second Rattrapantezange 39 apart from each other and thus spread from the Rattrapanterad 26 are lifted.

Das Rampenelement 16 besitzt jeweils eine einem Abtastnocken 13, 13' zugeordnete Rampe 52, 52' mit zueinander gerichteten Vertiefungen 53, 53'.The ramp element 16 has one each a Abtastnocken 13, 13 ' associated ramp 52, 52 'with mutually facing recesses 53, 53 '.

Zum Bewegen des Rampenelements 16 dient eine Stelleinrichtung, die einen um eine Schwenkachse 11 schwenkbaren zweiarmigen Hebel 9 aufweist. An dem Ende des einen Hebelarms des Hebels 9 ist eine Abtastnase 17 angeordnet, durch die die Stellung des Kolonnenrads 7 abtastbar ist. Das Ende des zweiten Hebelarms des Hebels 9 ist an dem Rampenelement 16 angelenkt.To move the ramp element 16 is an adjusting device, the a pivotable about a pivot axis 11 two-armed lever. 9 having. At the end of the one lever arm of the lever 9 is a Abtastnase 17 arranged through which the position of the column wheel 7 scanned is. The end of the second lever arm of the lever 9 is on the Ramp element 16 articulated.

Befindet sich die Abtastnase 17 in einem Tal e, f, g, h des Kolonnenrads 7, so ist der Hebel 16 in eine solche Position geschwenkt, daß die Abtastnocken 13, 13' sich im verjüngten Bereich des Rampenelements 16 in der Höhe der Vertiefungen 53, 53' befinden und in diese eingetaucht sind.
