Description

L'invention concerne un sautoir pour mouvement d'horlogerie. L'invention concerne aussi un mécanisme horloger comprenant un tel sautoir. L'invention concerne encore un mouvement horloger comprenant un tel mécanisme ou un tel sautoir. L'invention concerne encore une pièce d'horlogerie, notamment une montre, comprenant un tel mouvement ou un tel mécanisme ou un tel sautoir.The invention relates to a jumper for a watch movement. The invention also relates to a clock mechanism comprising such a jumper. The invention also relates to a watch movement comprising such a mechanism or such a jumper. The invention also relates to a timepiece, in particular a watch, comprising such a movement or such a mechanism or such a jumper.

On connaît différentes structures de sautoirs.Different jumper structures are known.

Le document EP1746470 divulgue un sautoir d'indexation d'un disque des quantièmes qui est constitué d'un levier-ressort sur lequel est fixé un bec à une des extrémités du levier. Le levier-ressort est mobile en rotation selon un axe de pivotement situé à une extrémité opposée de celle du bec, et ce dernier n'est pas déplaçable relativement au levier-ressort.The document EP1746470 discloses an indexing pin of a date disk which is constituted by a spring lever on which is fixed a spout at one end of the lever. The lever-spring is movable in rotation along a pivot axis located at an end opposite that of the spout, and the latter is not movable relative to the lever-spring.

Avec une telle structure de sautoir 100, comme représenté à la figure 1, en correction manuelle de date, il existe un risque de bloquer le disque 101 des quantièmes entre deux dates du fait d'un non-retour en position de repos du bec 102 de sautoir qui peut rester en appui stable à l'encontre du sommet de l'une des dents du disque. Par position de repos du bec de sautoir, nous entendons une position d'indexation de la denture du disque des quantièmes, par exemple une position dans laquelle le bec de sautoir est conventionnellement disposé entre deux dents du disque des quantièmes. Ce cas de figure s'explique par le fait que la force de réaction F du sommet de dent sur l'extrémité du bec de sautoir peut passer sensiblement par l'axe 104 de pivotement du disque des quantièmes. Dans cette configuration, le levier-ressort ne peut pas restituer l'énergie potentielle qu'il a accumulée, et il s'ensuit donc un état d'équilibre stable problématique car le disque ou l'organe, que le sautoir est destiné à indexer, ne se trouve pas dans une position définie, par exemple une position définie d'indication d'une date.With such a jumper structure 100, as shown in FIG. figure 1 in manual date correction, there is a risk of blocking the disk 101 of the dates between two dates due to a non-return to the rest position of the spout 102 which can remain in stable support against the top of one of the teeth of the disc. By rest position of the spout, we mean an indexing position of the teeth of the date disc, for example a position in which the spout is conventionally arranged between two teeth of the date disc. This case can be explained by the fact that the reaction force F of the tooth crown on the end of the jumping spout can pass substantially through the pivot axis 104 of the date disc. In this configuration, the lever-spring can not restore the potential energy that it has accumulated, and it follows therefore a stable equilibrium state problematic because the disc or the organ, that the jumper is intended to index, is not in a defined position, for example a defined position of indication of a date.

Le document EP1785783 divulgue un sautoir d'indexation d'un disque de date dont le fonctionnement est semblable à celui de la demande de brevet précitée. Une différence provient de l'architecture du sautoir qui est ici constitué d'un levier et d'un ressort-fil distincts. Le levier est mobile en rotation selon un axe de pivotement situé à une première extrémité du levier, et une deuxième extrémité du levier comporte une saillie faisant office de bec qui est pressée à l'encontre de la denture du disque des quantièmes sous l'effet du ressort-fil. Une telle construction ne permet pas d'annuler le risque de non-retour en position de repos du bec de sautoir.The document EP1785783 discloses an indexing jumper of a date disc whose operation is similar to that of the aforementioned patent application. A difference comes from the architecture of the jumper which consists here of a separate lever and a wire-spring. The lever is movable in rotation about a pivot axis located at a first end of the lever, and a second end of the lever comprises a projection serving as a nose which is pressed against the toothing of the date disk under the effect wire spring. Such a construction does not cancel the risk of no return to the rest position of the jumping spout.

Le document JP2004184259 divulgue une construction au sein de laquelle le bec du sautoir d'indexation est mobile en translation. Cette configuration n'annule en rien le risque de bloquer le disque des quantièmes entre deux dates du fait d'un unique degré de liberté de mouvement du bec de sautoir.The document JP2004184259 discloses a construction in which the spout of the indexing spider is movable in translation. This configuration does not cancel the risk of blocking the date disc between two dates due to a single degree of freedom of movement of the jumping spout.

La demande de brevet JP2008197036 décrit également un sautoir mobile en translation par la mise en oeuvre d'un guidage flexible. Cette architecture permet a priori d'obtenir les mêmes moments appliqués au disque des quantièmes quel que soit son sens de rotation, mais ne permet pas d'annuler la plage de rotation du disque des quantièmes dans laquelle le bec de sautoir et le disque des quantièmes peuvent être en équilibre stable.The patent application JP2008197036 also describes a jumper movable in translation by the implementation of a flexible guide. This architecture makes it possible, in principle, to obtain the same moments applied to the date disk regardless of its direction of rotation, but does not make it possible to cancel the range of rotation of the date disc in which the spout and the disc of the calendars can be in stable equilibrium.

Au vu de cet état de l'art, il apparaît que les sautoirs connus comportent généralement une saillie en forme de bec qui appuie à l'encontre de deux dents consécutives d'une roue sous l'effet d'un premier ressort de rappel. Ainsi, la roue est maintenue précisément dans une position angulaire stable et déterminée. Lorsque cette roue est entraînée en rotation sur plus d'un demi-pas angulaire, une de ses dents mène le bec du sautoir jusqu'à ce que le bec atteigne la tête de ladite dent, puis ce dernier est rappelé élastiquement à l'encontre de la dent successive de sorte à ce que la roue effectue un pas angulaire complet et se positionne à nouveau dans une position angulaire stable. C'est le cas notamment du disque des quantièmes d'un calendrier simple, qui est entraîné tous les jours à minuit par un mobile de calendrier conformé pour fournir une impulsion telle que le bec de sautoir dépasse le sommet de denture et repositionne convenablement le disque des quantièmes à chaque saut. Ce dernier peut néanmoins être actionné de manière indéterminée, par exemple par le biais d'un mécanisme de correction manuelle de date qui est susceptible de l'entraîner d'une valeur de l'ordre d'un demi-pas angulaire. Une telle configuration risque de bloquer le disque des quantièmes entre deux dates du fait du non-retour en position de repos du bec de sautoir qui peut rester en appui stable à l'encontre du sommet de l'une des dents du disque. Il en résulte une perte de l'information du mécanisme de calendrier et un désagrément visuel.In view of this state of the art, it appears that the known jumpers generally comprise a projection in the form of spout which bears against two consecutive teeth of a wheel under the effect of a first return spring. Thus, the wheel is held precisely in an angular position stable and determined. When this wheel is rotated over more than a half-angular step, one of its teeth leads the beak of the saltire until the beak reaches the head of said tooth, then the latter is elastically biased against of the successive tooth so that the wheel takes a complete angular step and is positioned again in a stable angular position. This is particularly the case of the disc of calendars of a simple calendar, which is driven every day at midnight by a calendar mobile shaped to provide an impulse such that the jumping nose protrudes from the top of the teeth and repositions the disc properly. dates on each jump. The latter can nevertheless be operated indefinitely, for example by means of a manual date correction mechanism which is likely to cause a value of the order of one half an angular step. Such a configuration may block the date disc between two dates due to the non-return to the rest position of the jumping nose which can remain in stable support against the top of one of the teeth of the disc. This results in a loss of calendar mechanism information and visual annoyance.

Un premier élément 200 de rappel de la tête de sautoir dans une première position est de préférence adapté pour rappeler la tête de sautoir vers la première position selon un premier sens et selon un deuxième sens, notamment selon les sens trigonométriques et anti-trigonométriques représentés sur les figures.A first element 200 for returning the jumping head to a first position is preferably adapted to return the jumping head to the first position in a first direction and in a second direction, in particular according to the trigonometric and anti-trigonometric directions shown in FIG. the figures.

Le corps de sautoir, délimité par une première extrémité 281 et une deuxième extrémité 282, comprend, dans ce mode de réalisation, principalement un bras principal 202, un premier bras auxiliaire 209 et un deuxième bras auxiliaire 220.The jumbo body, delimited by a first end 281 and a second end 282, comprises, in this embodiment, mainly a main arm 202, a first auxiliary arm 209 and a second auxiliary arm 220.

Préférentiellement, le bras principal est indéformable ou quasiment indéformable en utilisation conventionnelle du sautoir.Preferably, the main arm is dimensionally stable or almost indeformable in conventional use of the jumper.

Le premier bras auxiliaire 209 fait partie du premier élément 200 de rappel de la tête de sautoir dans une première position relativement au corps de sautoir, en particulier relativement au bras principal. Le premier élément de rappel permet notamment de rappeler élastiquement la tête de sautoir dans la première position relativement au corps de sautoir, en particulier relativement au bras principal. La première position est notamment représentée sur les figures 2, 3 et 9.The first auxiliary arm 209 is part of the first return element 200 of the jumper head in a first position relative to the jumper body, in particular relative to the main arm. The first return element allows in particular elastically recall the jumping head in the first position relative to the jumper body, in particular relative to the main arm. The first position is represented on the figures 2 , 3 and 9 .

Le premier bras auxiliaire et/ou le premier élément de rappel est par exemple un bras flexible venu de matière avec le reste du corps, notamment avec le bras principal. Le premier bras auxiliaire est par exemple lié au reste du corps, notamment au bras principal au niveau de la deuxième extrémité 282 du corps.The first auxiliary arm and / or the first return element is for example a flexible arm integral with the rest of the body, in particular with the main arm. The first auxiliary arm is for example linked to the rest of the body, in particular to the main arm at the second end 282 of the body.

Le deuxième bras auxiliaire 220 constitue un ou fait partie d'un deuxième élément 220 de rappel du corps de sautoir, en particulier du bras principal, dans une deuxième position relativement au bâti. Le deuxième élément de rappel permet notamment de rappeler élastiquement le corps de sautoir, en particulier le bras principal, dans la deuxième position relativement au bâti. La deuxième position est notamment représentée sur les figures 3 et 9. Le deuxième bras auxiliaire et/ou le deuxième élément de rappel est par exemple un bras flexible venu de matière avec le reste du corps, notamment avec le bras principal. Le deuxième bras auxiliaire est par exemple lié au reste du corps, notamment au bras principal au niveau de la deuxième extrémité 282 du corps.The second auxiliary arm 220 constitutes one or is part of a second element 220 for returning the jumper body, in particular the main arm, in a second position relative to the frame. The second return element in particular allows to elastically recall the jumper body, in particular the main arm, in the second position relative to the frame. The second position is represented in particular figures 3 and 9 . The second auxiliary arm and / or the second return element is for example a flexible arm integral with the rest of the body, in particular with the main arm. The second auxiliary arm is for example linked to the rest of the body, in particular to the main arm at the second end 282 of the body.

Le deuxième élément de liaison 293 comprend de préférence une goupille ou un axe 203b, respectivement un alésage, prévu sur le sautoir, notamment au niveau de la deuxième extrémité 282 du corps, et destiné à coopérer avec un alésage, respectivement une goupille ou un axe, prévu sur le bâti. Une telle structure permet de réaliser une liaison pivot du sautoir sur le bâti autour d'un axe. Le deuxième élément de rappel permet de rappeler en rotation, vers sa deuxième position, le sautoir autour de l'axe 203b. Pour ce faire, le deuxième bras auxiliaire prend par exemple appui sur un élément 206, notamment une butée, prévue sur le bâti. Dans la deuxième position, la première extrémité 281 du sautoir est positionnée de sorte que la tête du sautoir s'engage dans des conformations 250 de l'organe 205 avec laquelle elle est destinée à coopérer. Le deuxième bras auxiliaire permet de générer un couple résistif M2 relativement à l'axe 203b et ainsi permettre le maintien en position angulaire de l'organe comme représenté à la figure 3.The second connecting element 293 preferably comprises a pin or an axis 203b, respectively a bore, provided on the jumper, in particular at the second end 282 of the body, and intended to cooperate with a bore, respectively a pin or an axis. , planned on the frame. Such a structure allows a pivot connection of the jumper on the frame about an axis. The second return element makes it possible to return the jumper around the axis 203b in rotation towards its second position. To do this, the second auxiliary arm takes for example support on an element 206, including a stop, provided on the frame. In the second position, the first end 281 of the jumper is positioned so that the head of the jumper engages in conformations 250 of the member 205 with which it is intended to cooperate. The second auxiliary arm can generate a couple resistive M2 relative to the axis 203b and thus allow maintaining the angular position of the member as shown in FIG. figure 3 .

Le premier élément de liaison 292 comprend de préférence une goupille ou un axe 202a solidaire du corps de sautoir, notamment au niveau de la première extrémité 281 du corps, qui est prévu pour coopérer avec un alésage 203a formé sur la tête de sautoir. Ainsi, dans le mode de réalisation représenté aux figures 2 à 11, la structure permet de réaliser une liaison pivot de la tête sur le corps de sautoir autour d'un axe 292a. Le premier élément de rappel permet de rappeler en rotation, vers sa première position, la tête autour de l'axe 292a.The first connecting element 292 preferably comprises a pin or an axis 202a integral with the jumper body, in particular at the first end 281 of the body, which is intended to cooperate with a bore 203a formed on the jumping head. Thus, in the embodiment shown in Figures 2 to 11 , the structure allows for a pivot connection of the head on the body of the jumper around an axis 292a. The first biasing element makes it possible to rotate the head around the axis 292a in rotation towards its first position.

La tête comprend deux flancs 231 et 232. Ces deux flancs forment un angle, notamment un angle obtus. Les deux flancs sont destinés à venir en contact contre les conformations, notamment contre les dents, de l'élément 205 que le sautoir est destiné à indexer en position.The head comprises two flanks 231 and 232. These two flanks form an angle, including an obtuse angle. The two flanks are intended to come into contact with the conformations, in particular against the teeth, of the element 205 that the jumper is intended to index in position.

La tête comprend également un flanc de came 230, notamment un flanc de came en forme de vé, apte à coopérer avec un suiveur de came tel qu'un pion, une goupille ou plus généralement un axe 204, agencé sur le premier bras auxiliaire 209, notamment à l'extrémité du premier bras auxiliaire. Le suiveur de came est rappelé contre le flanc de came par un organe élastique constitué par le premier bras auxiliaire 209.The head also comprises a cam flank 230, in particular a cam-shaped cam flank capable of cooperating with a cam follower such as a peg, a pin or more generally an axis 204, arranged on the first auxiliary arm 209. , especially at the end of the first auxiliary arm. The cam follower is biased against the cam flank by an elastic member constituted by the first auxiliary arm 209.

Outre le premier bras auxiliaire 209, le premier élément 200 de rappel de la tête comprend l'axe 204 et le flanc de came 230. Ainsi, le premier élément de rappel est prévu pour générer un couple résistif M3 relativement à l'axe 292a et pour maintenir en position la tête dans une position angulaire déterminée.In addition to the first auxiliary arm 209, the first element 200 for returning the head comprises the axis 204 and the cam flank 230. Thus, the first return element is provided to generate a resistive torque M3 relative to the axis 292a and to hold the head in position in a certain angular position.

Dans le mode de réalisation représenté, l'organe élastique comprend le premier bras auxiliaire 209 et le suiveur de came ou le flanc de came. En effet, le suiveur de came peut être prévu sur le premier bras auxiliaire, notamment à une extrémité du premier bras auxiliaire, et le flanc de came peut être prévu sur la tête. Alternativement, le flanc de came peut être prévu sur le premier bras auxiliaire, notamment à une extrémité du premier bras auxiliaire, et le suiveur de came peut être prévu sur la tête.In the embodiment shown, the resilient member includes the first auxiliary arm 209 and the cam follower or cam flank. In Indeed, the cam follower may be provided on the first auxiliary arm, in particular at one end of the first auxiliary arm, and the cam flank may be provided on the head. Alternatively, the cam flank may be provided on the first auxiliary arm, in particular at one end of the first auxiliary arm, and the cam follower may be provided on the head.

Le flanc de came peut être conformé comme un vé.The cam flank can be shaped like a vee.

Ainsi, le sautoir 201 comprend un levier-ressort sur lequel est montée en rotation la tête de sautoir.Thus, the jumper 201 comprises a lever-spring on which is mounted in rotation the jumper head.

Dans le premier mode de réalisation, la tête de sautoir présente un mode de fonctionnement bidirectionnel. Ainsi, cette tête annule la plage angulaire de de non-retour en position de repos du sautoir quel que soit le sens de rotation de l'élément que le sautoir est destiné à indexer. Une telle solution est particulièrement bien adaptée à un disque des quantièmes susceptible d'être déplacé selon deux sens de correction.In the first embodiment, the jumper head has a bidirectional mode of operation. Thus, this head cancels the angular range of non-return in the rest position of the jumper irrespective of the direction of rotation of the element that the jumper is intended to index. Such a solution is particularly well suited to a date disk that can be moved in two directions of correction.

Nous considérons par la suite le cas d'une rotation dans le sens anti-trigonométrique de l'élément 205.We next consider the case of a rotation in the anti-trigonometric direction of the element 205.

Dans une première phase d'entraînement de l'élément 205 comme représenté à la figure 4, lorsque celui-ci est mené sur une plage angulaire de 0° à une valeur de l'ordre d'un quart de pas angulaire, la tête est entraînée en rotation dans le sens anti-trigonométrique uniquement autour de l'axe 293a sous l'actionnement d'un flanc 250a d'une dent 250 de l'élément 205 sur le flanc 232 de la tête. Le corps de sautoir est ainsi écarté de la deuxième position contre l'action du deuxième élément de rappel. Alternativement, la tête de sautoir peut tout d'abord être entraînée en rotation selon un premier sens de rotation uniquement autour de l'axe 292a dès lors qu'une dent 250 mène la tête de sautoir.In a first training phase of the element 205 as shown in FIG. figure 4 when the latter is run over an angular range of 0 ° to a value of the order of a quarter of an angular pitch, the head is rotated in the anti-trigonometric direction only about the axis 293a under the actuating a flank 250a of a tooth 250 of the element 205 on the flank 232 of the head. The jumper body is thus moved away from the second position against the action of the second return element. Alternatively, the jumper head may first be rotated in a first direction of rotation only about the axis 292a when a tooth 250 leads the jumping head.

Dans une deuxième phase d'entraînement de l'élément 205 comme représenté à la figure 5, lorsque celui-ci est mené sur une plage angulaire d'une valeur de l'ordre d'un quart de pas angulaire à une valeur de l'ordre d'un demi pas angulaire, la tête est également entraînée en rotation par le contact de la dent 250 sur le flanc 232 dans le sens anti-trigonométrique autour de l'axe 293a si bien que son flanc 230 arme le premier bras auxiliaire 209 par l'intermédiaire du suiveur de came 204. La tête est ainsi écartée de la première position contre l'action du premier élément de rappel. Ainsi, lorsque la tête 203 parvient en sommet de dent comme représenté à la figure 6, celle-ci est orientée relativement à la dent 250 de telle sorte que la force de réaction du sommet de dent sur la tête de sautoir ne soit pas dirigée vers l'axe de pivotement de l'élément 205. Plus particulièrement, la force de réaction F ne passe pas par le cercle dont le rayon Rf est défini par le rayon de guidage R de l'élément 205 ainsi que par le coefficient de frottement entre le disque des quantièmes et sa surface de guidage, plus particulièrement par le produit du rayon de guidage R et du sinus de l'arc-tangente du coefficient de frottement entre le disque des quantièmes et sa surface de guidage. Par ailleurs, la position de la tête relativement à l'axe 293a est instable si bien que le passage d'un flanc à l'autre de la dent s'effectue instantanément grâce à l'énergie emmagasinée dans le premier bras auxiliaire élastique 209 qui est libérée.In a second training phase of the element 205 as shown in FIG. figure 5 , when the latter is conducted over an angular range of a value of the order of a quarter of an angular pitch to a value of the order of one half an angular step, the head is also rotated by the contact of the tooth 250 on the side 232 in the anti-trigonometric direction about the axis 293a so that its side 230 arms the first auxiliary arm 209 via the cam follower 204. The head is thus removed from the first position against the action of the first return element. Thus, when the head 203 reaches the top of the tooth as shown in FIG. figure 6 it is oriented relative to the tooth 250 so that the reaction force of the tooth crown on the jumping head is not directed towards the axis of pivoting of the element 205. More particularly, the force of reaction F does not pass through the circle whose radius Rf is defined by the guide radius R of the element 205 as well as by the coefficient of friction between the date disc and its guide surface, more particularly by the product of the radius R guide and sinus arc-tangent coefficient of friction between the date disk and its guide surface. Moreover, the position of the head relative to the axis 293a is unstable so that the passage from one side to the other of the tooth takes place instantaneously thanks to the energy stored in the first elastic auxiliary arm 209 which is released.

Dans une troisième phase d'entraînement de l'élément 205 comme représenté à la figure 7, la restitution ou le retour en position de repos du premier bras auxiliaire élastique 209 induit la rotation de la tête 203 dans le sens trigonométrique autour de l'axe 293a, ce qui lui permet de franchir le sommet de la dent 250. Le flanc 231 de la tête mène alors un flanc de la dent 250 de l'élément 205. Dans cette configuration, la tête est mobile en rotation selon les axes 292a et 293a en sens trigonométrique. Dans une quatrième phase d'entraînement de l'élément 205 comme représenté à la figure 8, la tête est à nouveau en position stable relativement à l'axe 292a. Celui-ci est à nouveau mobile en rotation uniquement autour de l'axe 293a jusqu'à ce que le corps du sautoir parvienne à l'encontre d'une butée 207 ou que les flancs 231 et 232 de la tête viennent à l'encontre des flancs respectifs des dents 250 comme représenté à la figure 9.In a third training phase of the element 205 as shown in FIG. figure 7 , restitution or return to the rest position of the first elastic auxiliary arm 209 induces the rotation of the head 203 in the trigonometric direction about the axis 293a, which allows it to cross the top of the tooth 250. The flank 231 the head then leads a flank of the tooth 250 of the element 205. In this configuration, the head is rotatable along the axes 292a and 293a in the counterclockwise direction. In a fourth training phase of the element 205 as shown in FIG. figure 8 , the head is again in a stable position relative to the axis 292a. It is again rotatable only around the axis 293a until the body of the jumper is against a stop 207 or the flanks 231 and 232 of the head are against respective flanks of the teeth 250 as shown in FIG. figure 9 .

Le principe de fonctionnement du sautoir est le même pour une rotation dans le sens trigonométrique de l'élément 205, le flanc 230 de la tête 203 étant également conformé pour armer le premier bras auxiliaire élastique 209 par l'intermédiaire de la goupille 204 lorsque la tête tourne dans le sens trigonométrique comme représenté à la figure 10. Les actions des flancs 231 et 232 sont alors inversées.The operating principle of the jumper is the same for a rotation in the trigonometric direction of the element 205, the sidewall 230 of the head 203 is also shaped to arm the first elastic auxiliary arm 209 via the pin 204 when the head rotates in the counterclockwise direction as shown in figure 10 . The actions of the flanks 231 and 232 are then reversed.

Alternativement, ce sautoir, notamment la tête de sautoir, peut présenter un mode de fonctionnement qui se décompose plus simplement selon deux ou trois phases de rotation distinctes de l'élément 205. La tête peut ainsi être entraînée en rotation selon un premier sens de rotation vis-à-vis respectivement des axes 292a et 293a dès lors qu'une dent de l'élément 205 mène la tête, et ce jusqu'à ce que cette dernière atteigne sensiblement le sommet de ladite dent. La tête peut ensuite être entraînée en rotation selon un deuxième sens de rotation vis-à-vis respectivement des axes 292a et 293a dès lors que la tête franchit le sommet de la tête de dent de l'élément 205, et ce jusqu'à ce que le sautoir atteigne sa position de repos.Alternatively, this jumper, in particular the jumping head, may have a mode of operation which is more easily broken down into two or three distinct phases of rotation of the element 205. The head can thus be rotated in a first direction of rotation. vis-à-vis the axes respectively 292a and 293a since a tooth of the element 205 leads the head, until the latter substantially reaches the top of said tooth. The head can then be rotated in a second direction of rotation with respect to the axes 292a and 293a respectively, provided that the head passes through the top of the tooth head of the element 205, until the jumper reaches its rest position.

Optionnellement, en variante, la goupille 204 peut être mobile en rotation selon un troisième axe de rotation 204a, comme représenté à la figure 11. Ainsi, dans cette situation la goupille peut rouler sur le flanc de came plutôt que glisser contre celui-ci.Optionally, in a variant, the pin 204 can be rotatable about a third axis of rotation 204a, as shown in FIG. figure 11 . Thus, in this situation the pin can roll on the cam flank rather than slide against it.

Un deuxième mode de réalisation d'une pièce d'horlogerie 399, notamment une montre, en particulier une montre-bracelet est décrite ci-après en référence à la figure 12.A second embodiment of a timepiece 399, in particular a watch, in particular a wristwatch, is described hereinafter with reference to FIG. figure 12 .

La pièce d'horlogerie comprend un mouvement horloger 398.The timepiece comprises a watch movement 398.

Le mouvement horloger comprend un mécanisme horloger 397, par exemple un mécanisme de calendrier.The watch movement comprises a watch mechanism 397, for example a calendar mechanism.

Le mécanisme horloger comprend un sautoir 301 et un bâti 1 sur lequel est monté le sautoir, en particulier un corps 310 du sautoir. Le mécanisme comprend encore une roue ou un disque 305 en coopération avec le sautoir et un dispositif d'entraînement 360 de la roue ou du disque, notamment un dispositif d'entraînement de la roue ou du disque qui est distinct du sautoir. Le dispositif d'entraînement peut par exemple se présenter sous la forme d'une roue ou d'un doigt d'entraînement qui est lié cinématiquement à la chaîne de rouage d'un mouvement de base. Le dispositif d'entraînement peut également se présenter sous la forme d'un mécanisme de correction, comme une roue de correction ou une bascule.The clock mechanism comprises a jumper 301 and a frame 1 on which is mounted the jumper, in particular a body 310 of the jumper. The mechanism further comprises a wheel or disk 305 in cooperation with the jumper and a drive device 360 of the wheel or disk, in particular a drive device of the wheel or disk which is separate from the jumper. The driving device may for example be in the form of a wheel or a drive finger which is kinematically connected to the drive train of a basic movement. The driving device may also be in the form of a correction mechanism, such as a correction wheel or a rocker.

Le sautoir permet d'indexer en position, notamment angulairement en position, un élément 305 comme une roue ou une came ou encore un organe d'affichage, notamment un organe d'affichage d'une grandeur liée au temps tel qu'un disque des quantièmes.The jumper makes it possible to index in position, in particular angularly in position, an element 305 such as a wheel or a cam or else a display member, in particular a display member of a magnitude related to time such that a disc of calendars.

Comme représenté sur les figures 12 à 17, le deuxième mode de réalisation du sautoir 301 comprend le corps 310 de sautoir, une tête 303 de sautoir ou un bec de sautoir, un premier élément de liaison 392 de la tête de sautoir sur le corps de sautoir. Le premier élément de liaison 392 permet un mouvement de la tête 303 de sautoir relativement au corps 310 de sautoir. Le mouvement peut notamment comprendre un mouvement de rotation comme par exemple un mouvement composé d'un mouvement de rotation et d'un mouvement de translation. En particulier, le premier élément de liaison peut permettre uniquement un mouvement de rotation comme représenté sur les figures 12 à 17.As shown on Figures 12 to 17 the second embodiment of the jumper 301 comprises the jumper body 310, a jumper head 303 or a jumper spout, a first connecting element 392 of the jumper head on the jumper body. The first link member 392 allows movement of the jumper head 303 relative to the jumper body 310. The movement may include a rotational movement such as a movement consisting of a rotational movement and a translational movement. In particular, the first connecting element can only allow a rotational movement as shown on the Figures 12 to 17 .

Un élément du premier mode de réalisation et un élément du deuxième mode de réalisation ayant des fonctions identiques ou similaires portent des références ayant des chiffres des dizaines et des unités identiques. Le chiffre des centaines est un « 2 » pour la référence de l'élément du premier mode de réalisation et le chiffre des centaines est un « 3 » pour la référence de l'élément du deuxième mode de réalisation.An element of the first embodiment and an element of the second embodiment having the same or similar functions carry references having numbers of tens and identical units. The hundreds digit is a "2" for the element reference of the first embodiment and the hundreds digit is a "3" for the element reference of the second embodiment.

Le deuxième mode de réalisation diffère principalement du premier mode de réalisation en ce que le premier élément de rappel de la tête de sautoir dans la première position relativement au corps de sautoir est adapté pour rappeler la tête de sautoir vers la première position selon un premier sens, la première position étant définie par une première butée 350 solidaire du corps de sautoir.The second embodiment differs mainly from the first embodiment in that the first return element of the jumping head in the first position relative to the jumper body is adapted to return the jumping head to the first position in a first direction. , the first position being defined by a first abutment 350 integral with the jumper body.

Avantageusement, le premier élément de rappel comprend une lame ressort 300 solidaire de la tête de sautoir, respectivement solidaire du corps de sautoir, coopérant par contact avec une deuxième butée 350 prévue sur le corps de sautoir, respectivement sur la tête de sautoir.Advantageously, the first return element comprises a spring blade 300 integral with the jumping head, respectively integral with the jumper body, cooperating by contact with a second stop 350 provided on the jumping body, respectively on the jumping head.

Dans le deuxième mode de réalisation comme représenté aux figures 12 et 13, la première et la deuxième butées sont réalisées par une seule et même butée. La tête de sautoir présente un mode de fonctionnement unidirectionnel de façon à supprimer la plage de non-retour en position de repos du sautoir pour un unique sens de rotation de l'élément 305 avec lequel il coopère. Le sautoir permet d'indexer en position cet élément 305.In the second embodiment as shown in figures 12 and 13 the first and second stops are made by one and the same stop. The jumper head has a unidirectional operating mode so as to eliminate the range of no return in the rest position of the jumper for a single direction of rotation of the element 305 with which it cooperates. The jumper allows to index in position this element 305.

Contrairement au premier mode de réalisation, le sautoir ne présente pas de premier bras auxiliaire. Comme vu plus haut, le premier élément de rappel de la tête de sautoir dans la première position relativement au corps de sautoir comprend ici une lame-ressort 300 ou un ressort. Ce ressort est par exemple solidarisé à la tête 303 par soudage. Ce ressort est pré-armé par une butée ou une goupille 350 rapportée sur le bras principal302. Le ressort prend en effet appui contre la butée. La butée 350 permet aussi d'arrêter la tête dans une position prédéterminée qui correspond à la position de butée de la tête contre la butée. Il peut bien sûr exister deux butées, l'une pour servir d'appui au ressort et une pour arrêter la tête dans une position prédéfinie.Unlike the first embodiment, the jumper does not have a first auxiliary arm. As seen above, the first return element of the jumper head in the first position relative to the jumper body here comprises a spring blade 300 or a spring. This spring is for example secured to the head 303 by welding. This spring is pre-armed by a stop or a pin 350 attached to the main arm 302. The spring takes effect against the stop. The stop 350 also makes it possible to stop the head in a predetermined position which corresponds to the stop position of the head against the stop. There can of course be two stops, one to support the spring and one to stop the head in a predefined position.

Pour un unique sens de rotation de l'élément 305, par exemple une rotation dans le sens anti-trigonométrique comme représentée aux figures 15 à 17, le principe de fonctionnement de ce sautoir est identique à celui du premier mode de réalisation. Ce sautoir présente également un mode de fonctionnement qui peut être décomposé en deux, trois, ou quatre phases de rotation du disque des quantièmes.For a single direction of rotation of the element 305, for example a rotation in the anti-trigonometric direction as represented in FIGS. Figures 15 to 17 , the operating principle of this jumper is identical to that of the first embodiment. This jumper also has a mode of operation that can be broken down into two, three, or four phases of rotation of the date disc.

La figure 14 illustre le sautoir au repos. La figure 15 représente la rotation de la tête dans le sens anti-trigonométrique vis-à-vis respectivement des axes 392a et 393a sous l'actionnement du flanc 350a de la dent 350. La figure 16 représente la tête positionnée sensiblement en sommet de dent. Son positionnement est alors instable sous l'effet du ressort 300. La figure 17 illustre la tête une fois que celle-ci a franchi le sommet de dent ; elle est alors mobile en rotation dans le sens trigonométrique vis-à-vis respectivement des axes 292a et 293a.The figure 14 illustrates the saltire at rest. The figure 15 represents the rotation of the head in the anti-trigonometric direction with respect to the axes 392a and 393a respectively under the actuation of the flank 350a of the tooth 350. figure 16 represents the head positioned substantially at the top of the tooth. Its positioning is then unstable under the effect of the spring 300. figure 17 illustrates the head once it has crossed the top of the tooth; it is then rotatable in the counterclockwise direction with respect to the axes 292a and 293a, respectively.

Dans un mode de réalisation alternatif, le corps de sautoir peut être mobile en translation selon un axe sensiblement parallèle au plan du bâti du mécanisme ou du mouvement horloger. Comme dans les premier et deuxième modes de réalisation, la tête du sautoir peut présenter un mode de fonctionnement uni- ou bidirectionnel.In an alternative embodiment, the jumper body may be movable in translation along an axis substantially parallel to the plane of the frame of the mechanism or the watch movement. As in the first and In another embodiment, the jumper head may have a single or bidirectional operating mode.

Ainsi, dans les différents modes de réalisation, le sautoir permet d'éviter les risques d'occurrence de situations dans lesquelles la tête de sautoir se trouve dans une situation stable non prévue et/ou non souhaitable par :

  • Une tête de sautoir mobile vis-à-vis du corps de sautoir.
  • Plus particulièrement, une tête de sautoir mobile en rotation autour d'un axe 292a, 392a selon deux sens de rotation, sur un pas angulaire de l'élément avec lequel il coopère.
  • Une tête de sautoir positionnée de manière stable par un élément de rappel. Le passage d'un flanc à l'autre d'une dent s'effectue instantanément grâce à l'énergie emmagasinée dans l'élément de rappel.
  • Préférentiellement, les axes 292a et 392a sont positionnés sur la bissectrice de l'angle formé par une première demi-droite ayant pour origine l'axe de pivotement de l'élément 205, 305 et passant par le sommet d'une première dent, et par une deuxième demi-droite ayant pour origine l'axe de pivotement de l'élément 205,305 et passant par le sommet d'une dent consécutive à la première dent, lorsque l'élément 205, 305 est au repos.
  • Préférentiellement, la tête de sautoir est également mobile en rotation autour d'un deuxième axe 293a, 393a.
  • Avantageusement, un couple résistif M3 relativement à l'axe 292a, 392a est supérieur au couple résistif M2 relativement à l'axe 293a, 393a produit par le premier élément de rappel 220, 320, sur une première phase de rotation du disque des quantièmes.
Thus, in the various embodiments, the jumper makes it possible to avoid the risks of occurrence of situations in which the jumper head is in a stable situation that is not anticipated and / or undesirable by:
  • A jumping head movable vis-à-vis the body of jumper.
  • More particularly, a jumping head movable in rotation about an axis 292a, 392a in two directions of rotation, on an angular pitch of the element with which it cooperates.
  • A jumping head positioned stably by a return member. The passage from one side to the other of a tooth is effected instantaneously thanks to the energy stored in the return element.
  • Preferably, the axes 292a and 392a are positioned on the bisector of the angle formed by a first half-line originating from the axis of pivoting of the element 205, 305 and passing through the apex of a first tooth, and by a second half-line originating from the axis of pivoting of the element 205,305 and passing through the vertex of a tooth consecutive to the first tooth, when the element 205, 305 is at rest.
  • Preferably, the jumping head is also rotatable about a second axis 293a, 393a.
  • Advantageously, a resistive torque M3 relative to the axis 292a, 392a is greater than the resistive torque M2 relative to the axis 293a, 393a produced by the first return element 220, 320, on a first phase of rotation of the date disk.

Dans les différents modes de réalisation précédemment décrits, le premier élément de liaison est de préférence un élément de guidage qui réalise une liaison pivot entre la tête de sautoir et le corps de sautoir. Dans les différents modes de réalisation précédemment décrits, le premier élément de rappel et /ou le deuxième élément de rappel peuvent se présenter sous la forme de guidages ou d'articulations flexibles.In the various embodiments described above, the first connecting element is preferably a guide element which provides a pivot connection between the jumping head and the jumper body. In the various embodiments described above, the first return element and / or the second return element may be in the form of guides or flexible hinges.

Un sautoir selon l'invention permet de minimiser les risques, voire d'éviter les risques, d'occurrence de situations dans lesquelles le sautoir se trouve dans une position d'équilibre alors qu'il n'est pas en position de repos.A jumper according to the invention makes it possible to minimize the risks, or even to avoid the risks, of occurrence of situations in which the jumper is in an equilibrium position while it is not in the rest position.

Dans les différents modes de réalisation précédemment décrits, le sautoir peut faire partie d'un mécanisme horloger, notamment un mécanisme de calendrier. Le sautoir coopère avec une roue ou un disque, en particulier coopère par contact avec une roue ou un disque, notamment coopère par contact avec une denture d'une roue ou d'un disque. Le sautoir permet ainsi d'indexer en position la roue ou le disque. La roue ou le disque, plus généralement le mécanisme, est actionnable par le biais d'un dispositif d'entraînement 260, 360 distinct du sautoir. Le dispositif d'entraînement peut par exemple se présenter sous la forme d'une roue d'entraînement qui est liée cinématiquement à la chaîne de rouage d'un mouvement de base. Le dispositif d'entraînement peut également se présenter sous la forme d'un mécanisme de correction, comme une roue de correction ou une bascule.In the various embodiments described above, the jumper may be part of a clock mechanism, including a calendar mechanism. The jumper cooperates with a wheel or disc, in particular cooperates by contact with a wheel or a disc, in particular cooperates by contact with a toothing of a wheel or disc. The jumper thus indexes in position the wheel or the disc. The wheel or the disc, more generally the mechanism, is actuable via a drive device 260, 360 separate from the jumper. The drive device may for example be in the form of a drive wheel which is kinematically connected to the drive train of a basic movement. The driving device may also be in the form of a correction mechanism, such as a correction wheel or a rocker.

Plus particulièrement, le disque peut être un disque de calendrier qui peut être entraîné en rotation via sa denture par le dispositif d'entraînement.More particularly, the disk may be a calendar disk which may be rotated via its toothing by the driver.

La tête du sautoir est en contact permanent avec la roue ou le disque qu'il indexe en position, notamment en contact permanent avec une denture de la roue ou du disque. Ceci est en particulier le cas lorsque la roue ou le disque n'est pas actionné par le dispositif d'entraînement.The head of the jumper is in permanent contact with the wheel or the disc which it indexes in position, in particular in permanent contact with a toothing of the wheel or the disc. This is particularly the case when the wheel or disc is not actuated by the driving device.

La tête de sautoir est rappelée par un premier élément de rappel élastique contre la roue ou le disque. Ainsi, la restitution de l'énergie mécanique de l'élément de rappel peut participer à l'entraînement de la roue ou du disque.The jumping head is biased by a first resilient return member against the wheel or disk. Thus, the return of the mechanical energy of the return element can participate in driving the wheel or disk.

Plus particulièrement, la tête de sautoir est agencée de telle sorte que la force de réaction produite entre celle-ci et la denture du disque ou de la roue à indexer est orientée pour éviter un blocage de la tête de sautoir au sommet d'une dent de la roue ou du disque ou éviter l'existence d'une position d'équilibre de la tête de sautoir au sommet d'une dent de la roue ou du disque, notamment lorsque la roue ou le disque est actionné par un dispositif d'entraînement.More particularly, the jumping head is arranged in such a way that the reaction force produced between it and the toothing of the disk or the wheel to be indexed is oriented to prevent a jamming of the jumping head at the top of a tooth. of the wheel or disc or to avoid the existence of a position of equilibrium of the jumping head at the top of a tooth of the wheel or the disc, in particular when the wheel or disc is actuated by a device of training.

Dans ce document, le terme « sautoir » signifie un organe terminé par une tête munie de deux plans inclinés qui appuient, par rappel élastique, entre les sommets et/ou les flancs de deux dents consécutives d'une roue pour la maintenir dans une certaine position. Lorsque la roue est déplacée, sous l'effet d'un organe d'entraînement distinct du sautoir, une dent soulève le sautoir par action sur la tête de sautoir. Le sautoir, en particulier la tête de sautoir, tombe ensuite entre la dent qui a soulevé le sautoir et une dent suivante.In this document, the term "jumper" means a body terminated by a head provided with two inclined planes that support, by elastic return, between the vertices and / or the flanks of two consecutive teeth of a wheel to maintain it in a certain position. When the wheel is moved under the effect of a separate driving member of the jumper, a tooth lifts the jumper by action on the jumping head. The jumper, especially the jumping head, then falls between the tooth that lifted the jumper and a subsequent tooth.
