Description

L'invention concerne un mécanisme horloger permettant de mémoriser une indication temporelle. L'invention concerne aussi un mouvement horloger comprenant un tel mécanisme de mémorisation d'une indication temporelle. L'invention concerne encore une pièce d'horlogerie, notamment une montre, comprenant un tel mouvement ou un tel mécanisme.The invention relates to a timepiece mechanism making it possible to memorize a time indication. The invention also relates to a timepiece movement comprising such a mechanism for memorizing a time indication. The invention also relates to a timepiece, in particular a watch, comprising such a movement or such a mechanism.

Des dispositifs de mémorisation d'une information horaire, notamment de la seconde, sont connus de l'état de l'art. Le chronographe à rattrapante en est un exemple connu.Devices for storing time information, in particular the second, are known from the state of the art. The split-seconds chronograph is a well-known example.

Dans ce type de chronographe, une deuxième aiguille des secondes, couramment appelée aiguille à rattrapante, est superposée à la trotteuse de chronographe. Lorsqu'on actionne le poussoir de chronographe pour déclencher le comptage du temps, l'aiguille de rattrapante reste superposée à la trotteuse. Une première pression sur le bouton poussoir de rattrapante induit l'arrêt de l'aiguille de rattrapante tandis que la trotteuse poursuit sa marche. Une deuxième pression sur le poussoir de rattrapante ramène l'aiguille de rattrapante sur la trotteuse.In this type of chronograph, a second seconds hand, commonly called a split-seconds hand, is superimposed on the chronograph second hand. When the chronograph pusher is pressed to start counting the time, the split-seconds hand remains superimposed on the second hand. A first press on the split-seconds push button causes the split-seconds hand to stop while the second hand continues to run. A second press on the split-seconds pusher brings the split-seconds hand back to the second hand.

Un tel dispositif est par exemple décrit dans l'ouvrage de B. Humbert intitulé «Le chronographe» (chapitre 13) ou au sein du brevet CH682201 . En complément du mécanisme conventionnel de chronographe, le dispositif du brevet CH682201 met en œuvre un système de commande, prévu pour piloter un mobile de rattrapante, qui est constitué d'une came de commande mobile en rotation, notamment une roue à colonnes, et d'une paire de pinces de blocage.Such a device is for example described in the work of B. Humbert entitled "The chronograph" (chapter 13) or in the patent CH682201 . In addition to the conventional chronograph mechanism, the patent device CH682201 implements a control system, designed to drive a split-seconds wheel, which consists of a rotating control cam, in particular a column wheel, and a pair of locking pliers.

Outre le fait qu'il mette en œuvre un nombre conséquent de composants, notamment un dispositif complexe d'embrayage de chronographe qui permet de relier sélectivement le mobile de rattrapante au rouage de finissage du mouvement de base, le principal inconvénient du chronographe à rattrapante conventionnel est qu'il ne peut mémoriser un temps supérieur à la minute. Pour remédier à ce défaut, la demande de brevet EP1584997 divulgue un chronographe à rattrapante qui permet la mémorisation de la seconde et de la minute d'un temps chronométré. Ainsi, la capacité de mémorisation de la rattrapante n'est plus limitée à soixante secondes mais étendue au nombre de minutes qui sont affichées par le compteur de minutes du chronographe, trente minutes en l'occurrence. Ce dispositif met en œuvre un mobile de rattrapante des minutes dont la particularité est d'être actionné par la même roue à colonnes que celle actionnant le mobile de rattrapante des secondes. Une telle solution convient car les deux mobiles de rattrapante sont disposés sur un même côté du bâti de la pièce d'horlogerie. Ce système présente toutefois deux inconvénients. D'une part, le mécanisme de mémorisation est tributaire du mécanisme de chronographe dans la mesure où le mobile de rattrapante des minutes est lié cinématiquement à la chaîne de comptage du chronographe. D'autre part, la capacité de mémorisation du dispositif reste limité au nombre de minutes qui sont affichées par le compteur de minutes du chronographe.Apart from the fact that it uses a large number of components, in particular a complex chronograph clutch device which allows the split-seconds wheel set to be selectively connected to the going train of the base movement, the main drawback of the conventional split-seconds chronograph is that it cannot memorize a time greater than one minute. To remedy this defect, the patent application EP1584997 discloses a split-seconds chronograph which allows memorization of the second and the minute of a measured time. Thus, the split-seconds memory capacity is no longer limited to sixty seconds but extended to the number of minutes displayed by the chronograph minute counter, thirty minutes in this case. This device implements a split-seconds mobile whose particularity is to be actuated by the same column wheel as that actuating the split-seconds mobile. Such a solution is suitable because the two split-seconds wheels are arranged on the same side of the frame of the timepiece. However, this system has two drawbacks. On the one hand, the memorizing mechanism is dependent on the chronograph mechanism insofar as the minutes flywheel is kinematically linked to the counting chain of the chronograph. On the other hand, the storage capacity of the device remains limited to the number of minutes which are displayed by the minute counter of the chronograph.

Le document EP2410388A1 décrit une montre à double affichage. Un affichage, dit principal, comporte deux aiguilles, alors qu'un affichage, dit secondaire ou additionnel, en comporte trois. Dans ce document, il est prévu un mode de fonctionnement dans lequel les deux affichages indiquent, en même temps, l'heure du jour. De plus, des modes de fonctionnement supplémentaires, dans lesquels le deuxième affichage est dédié à une fonction différente, par exemple, un affichage chrono, sont prévus. L'utilisateur a le choix de passer d'un mode de fonctionnement à l'autre.The document EP2410388A1 describes a dual display watch. A so-called main display comprises two hands, while a so-called secondary or additional display comprises three. In this document, an operating mode is provided in which the two displays indicate, at the same time, the time of day. Furthermore, additional operating modes, in which the second display is dedicated to a different function, for example, a chrono display, are provided. The user has the choice of switching from one operating mode to another.

Le document EP2136271A1 décrit une montre chronographe laquelle comporte trois aiguilles pour l'heure courante et trois aiguilles de chronographe.The document EP2136271A1 describes a chronograph watch which comprises three hands for the current time and three chronograph hands.

Il semble donc qu'il n'existe pas de mécanisme de mémorisation d'un temps ou d'un horaire à la seconde près avec une capacité de mémorisation supérieure à l'heure, voire supérieure à trente minutes.It therefore seems that there is no mechanism for storing a time or a schedule to the nearest second with a storage capacity greater than the hour, or even greater than thirty minutes.

Le but de l'invention est de fournir un mécanisme horloger permettant de remédier aux inconvénients mentionnés précédemment et d'améliorer les mécanismes horlogers connus de l'art antérieur. En particulier, l'invention propose un mécanisme horloger et un mouvement horloger simple et fiable permettant d'afficher un horaire mémorisé à la seconde près, voire à une fraction de seconde près.The object of the invention is to provide a horological mechanism making it possible to to remedy the aforementioned drawbacks and to improve the clockwork mechanisms known from the prior art. In particular, the invention proposes a watch mechanism and a watch movement that is simple and reliable to display a memorized time to the nearest second, or even to a fraction of a second.

Ce but est atteint par un mécanisme tel que défini dans la revendication indépendante 1 annexée.

Un mode de réalisation d'une pièce d'horlogerie 1 selon l'invention est décrit ci-après en référence aux figures 1 à 3. Dans ce mode de réalisation de pièce d'horlogerie, des organes de mémorisation H', M', S', notamment des aiguilles additionnelles, permettant d'indiquer ou d'afficher des heures mémorisées, des minutes mémorisées et des secondes mémorisées, sont adjointes à des organes H, M, S conventionnels d'indication ou d'affichage, notamment des aiguilles conventionnelles H, M, S. La pièce d'horlogerie permet ainsi de mémoriser un horaire à la seconde près tout en indiquant l'heure courante. Elle permet en particulier d'afficher un horaire à la seconde près dans une plage temporelle s'étendant sur plusieurs heures, notamment 12 heures, voire 24 heures.An embodiment of a timepiece 1 according to the invention is described below with reference to the figures 1 to 3 . In this embodiment of a timepiece, storage elements H', M', S', in particular additional hands, making it possible to indicate or display stored hours, stored minutes and stored seconds, are attached to conventional H, M, S indication or display members, in particular conventional H, M, S hands. The timepiece thus makes it possible to memorize a time to the nearest second while indicating the current time . It makes it possible in particular to display a time to the nearest second in a time range extending over several hours, in particular 12 hours, or even 24 hours.

La pièce d'horlogerie est par exemple une montre, notamment une montre-bracelet. La pièce d'horlogerie comprend un mouvement horloger 2. Le mouvement horloger 2 comprend quant-à lui un mécanisme horloger 3 qui est décrit plus bas en détail. Ce mécanisme horloger 3 comprend des organes d'affichage H, M, S, H', M', S' permettant d'indiquer ou d'afficher les heures, minutes, secondes, voire les fractions de seconde courantes et d'indiquer ou d'afficher les heures, minutes, secondes, voire les fractions de seconde mémorisées. Le mécanisme peut par exemple comprendre un organe d'indication des fractions de secondes courantes et/ou un organe d'indication des fractions de secondes mémorisées. Ces organes d'indication peuvent par exemple être mis en œuvre par des mécanismes de seconde foudroyante. Par la suite, pour simplifier, on ne considère que des organes d'affichage des heures, minutes et secondes et pas d'organe d'affichage des fractions de secondes.The timepiece is for example a watch, in particular a wristwatch. The timepiece comprises a timepiece movement 2. The timepiece movement 2 itself comprises a timepiece mechanism 3 which is described in detail below. This horological mechanism 3 comprises display members H, M, S, H', M', S' making it possible to indicate or display the current hours, minutes, seconds, even fractions of a second and to indicate or to display the stored hours, minutes, seconds, even fractions of a second. The mechanism may for example comprise a member for indicating the current fractions of seconds and/or a member for indicating the stored fractions of seconds. These indication members can for example be implemented by jumping seconds mechanisms. Subsequently, for simplicity, only hours, minutes and seconds display members are considered and no fractional seconds display member.

En fonctionnement normal, comme représenté à la figure 1, les organes H, M, S d'affichage des heures, minutes et secondes courantes et les organes H', M', S' d'affichage des heures, minutes et secondes mémorisées indiquent l'heure courante.In normal operation, as shown in figure 1 , the members H, M, S for displaying the current hours, minutes and seconds and the members H', M', S' for displaying the stored hours, minutes and seconds indicate the current time.

Une première action sur un organe 4 de commande, comme une pression sur un poussoir, induit l'immobilisation des organes H', M', S' d'affichage des heures, minutes et secondes mémorisées sans pour autant agir sur les organes H, M, S d'affichage des heures, minutes et secondes courantes qui poursuivent leur course, comme représenté à la figure 2. Ainsi, dans cette configuration, les organes H', M', S' indiquent une information temporelle mémorisée.A first action on a control member 4, such as pressing a pusher, induces the immobilization of the members H′, M′, S′ for displaying the stored hours, minutes and seconds without acting on the members H, M, S for displaying the current hours, minutes and seconds which continue their run, as shown in figure 2 . Thus, in this configuration, the members H′, M′, S′ indicate stored time information.

Une deuxième action sur l'organe 4 de commande, par exemple une pression sur le poussoir, déclenche un repositionnement ou une resynchronisation des organes H', M', S' d'affichage des heures, minutes et secondes mémorisées avec les organes H, M, S d'affichage des heures, minutes et secondes courantes comme représenté à la figure 3. Les organes H', M', S' d'affichage des heures, minutes et secondes mémorisées et les organes H, M, S d'affichage des heures, minutes et secondes courantes sont ainsi à nouveau synchronisés. Les organes H', M', S' d'affichage des heures, minutes et secondes mémorisées et les organes H, M, S d'affichage des heures, minutes et secondes courantes affichent donc les mêmes indications.A second action on the control member 4, for example pressing the pusher, triggers a repositioning or a resynchronization of the members H′, M′, S′ for displaying the hours, minutes and seconds stored with the members H, M, S for displaying the current hours, minutes and seconds as shown in picture 3 . The members H', M', S' for displaying the stored hours, minutes and seconds and the members H, M, S for displaying the current hours, minutes and seconds are thus again synchronized. The members H', M', S' for displaying the stored hours, minutes and seconds and the members H, M, S for displaying the current hours, minutes and seconds therefore display the same indications.

Un mode de réalisation du mécanisme horloger 3 d'indication et de mémorisation d'une information temporelle est maintenant décrit plus en détail en référence aux figures 4 à 17.An embodiment of the timepiece mechanism 3 for indicating and storing time information is now described in more detail with reference to the figures 4 to 17 .

Selon un premier aspect de l'invention, le mécanisme 3 d'indication et de mémorisation d'une information temporelle comprend :

  • un organe H d'affichage des heures, un organe M d'affichage des minutes et un organe S d'affichage des secondes, voire un organe d'affichage des fractions de seconde, et
  • un organe H' d'affichage des heures mémorisées, un organe M' d'affichage des minutes mémorisées et un organe S' d'affichage des secondes mémorisées, voire un organe d'affichage des fractions de seconde mémorisées.
According to a first aspect of the invention, the mechanism 3 for indicating and storing time information comprises:
  • a device H for displaying the hours, a device M for displaying the minutes and a device S for displaying the seconds, or even a device for displaying fractions of a second, and
  • a member H' for displaying the stored hours, a member M' for displaying the stored minutes and a member S' for displaying the stored seconds, or even a member for displaying the stored fractions of a second.

Avantageusement, selon ce premier aspect de l'invention, le mécanisme comprend un premier dispositif MEM1 de mémorisation des secondes, voire de mémorisation des fractions de seconde et au moins un deuxième dispositif MEM2 de mémorisation des minutes et/ou des heures.Advantageously, according to this first aspect of the invention, the mechanism comprises a first device MEM1 for storing seconds, or even for storing fractions of a second and at least one second device MEM2 for storing minutes and/or hours.

Selon un deuxième aspect de l'invention, le mouvement horloger 2 comprend le mécanisme 3 d'indication et de mémorisation d'une information temporelle, ce mécanisme incluant :

  • un organe S' d'affichage des secondes mémorisées et/ou de fractions de secondes mémorisées,
  • un premier dispositif MEM1 de mémorisation des secondes et/ou de fractions de secondes.
According to a second aspect of the invention, the watch movement 2 comprises the mechanism 3 for indicating and storing time information, this mechanism including:
  • a device S' for displaying the stored seconds and/or stored fractions of seconds,
  • a first device MEM1 for storing seconds and/or fractions of seconds.

Le premier dispositif de mémorisation MEM1 comprend en outre un premier mobile M1 de mémorisation doté d'un premier élément MC1 de mémorisation en prise directe avec un élément 12 d'un rouage 11, 12, 13, 14, 15 de finissage du mouvement horloger ou un premier élément de mémorisation fixé sur un élément d'un rouage de finissage du mouvement horloger.The first storage device MEM1 further comprises a first storage mobile M1 provided with a first storage element MC1 in direct engagement with an element 12 of a cog 11, 12, 13, 14, 15 for finishing the watch movement or a first element of memorization fixed to an element of a going train of the watch movement.

De préférence, le premier élément de mémorisation est en liaison permanente avec l'élément 12 du rouage de finissage du mouvement horloger.Preferably, the first storage element is in permanent connection with the element 12 of the going train of the timepiece movement.

Le mécanisme comprend aussi un organe S d'affichage des secondes et/ou de fractions de secondes,The mechanism also includes a member S for displaying seconds and/or fractions of seconds,

Le premier dispositif de mémorisation MEM1 réalise une interface entre le rouage de finissage ou la chaîne de finissage et l'organe S' d'affichage des secondes mémorisées, notamment entre une roue des secondes 12 et l'organe S' d'affichage des secondes mémorisées. Comme représenté à la figure 4, le rouage de finissage peut comprendre un barillet 15, par exemple une roue de centre 14, par exemple une roue de moyenne 13, une roue de secondes 12 et une roue d'échappement 11. Le rouage de finissage peut présenter, du barillet à l'oscillateur, une structure tout à fait conventionnelle. Alternativement, le rouage de finissage peut comporter plusieurs barillets, et plus de trois mobiles de façon à lier cinématiquement le ou les barillets et la roue d'échappement.The first storage device MEM1 forms an interface between the going train or the finishing chain and the member S' for displaying the stored seconds, in particular between a seconds wheel 12 and the member S' for displaying the seconds stored. As depicted at figure 4 , the going train may comprise a barrel 15, for example a center wheel 14, for example an average wheel 13, a seconds wheel 12 and an escapement wheel 11. The going train may have, from the barrel to the oscillator, a completely conventional structure. Alternatively, the going train may comprise several barrels, and more than three mobiles so as to kinematically link the barrel or barrels and the escape wheel.

Le premier dispositif de mémorisation MEM1 est décrit ci-après en référence aux figures 5 à 9. Le premier dispositif de mémorisation comprend :

  • un premier mobile M1 de mémorisation doté d'un premier élément MC1 de mémorisation destiné à être en prise avec une chaîne cinématique 11, 12, 13, 14, 15 qui est dédiée au dit mobile.
The first storage device MEM1 is described below with reference to the figures 5 to 9 . The first storage device comprises:
  • a first storage mobile M1 provided with a first storage element MC1 intended to engage with a kinematic chain 11, 12, 13, 14, 15 which is dedicated to said mobile.

Plus précisément, le premier dispositif de mémorisation comprend, outre le premier mobile M1 :

  • un pignon 1a solidaire de la roue des secondes 12 (et donc solidaire de l'organe S d'affichage des secondes) et en prise, notamment en engrènement, avec le premier mobile M1 de mémorisation, et
  • un pignon 1a' solidaire de l'organe S' d'affichage des secondes mémorisées et en prise, notamment en engrènement, avec le premier mobile M1 de mémorisation.
More specifically, the first storage device comprises, in addition to the first mobile M1:
  • a pinion 1a secured to the seconds wheel 12 (and therefore secured to the seconds display member S) and in engagement, in particular in mesh, with the first storage mobile M1, and
  • a pinion 1a' secured to the member S' for displaying the stored seconds and in engagement, in particular in mesh, with the first storage mobile M1.

Plus précisément, le mobile de mémorisation M1 comprend un pignon M1a sur lequel est monté ou fixé le premier élément MC1 de mémorisation comprenant par exemple une came MC10, notamment une came en forme de cœur. Ce pignon M1a peut être continuellement engrené avec le pignon 1a du mobile des secondes 12. Le mobile de mémorisation M1 comprend une roue M1a' qui est en prise avec la roue 1a' du mobile 12' sur lequel est monté ou dont fait partie l'organe S' d'indication des secondes mémorisées, notamment sur lequel est chassée l'aiguille de mémorisation S'. Cette roue M1a' est également solidaire d'un plateau MP1 sur lequel pivote un levier de rappel élastique ML1. La roue M1a' et le plateau MP1 sont avantageusement fixés l'un sur l'autre. La roue1a' et l'organe d'affichage S' des secondes mémorisées sont reliés par un arbre traversant de part en part le bâti B du mouvement 2 de la pièce d'horlogerie 1, comme représenté à la figure 5.More specifically, the storage mobile M1 comprises a pinion M1a on which is mounted or fixed the first storage element MC1 comprising for example a cam MC10, in particular a heart-shaped cam. This pinion M1a can be continuously meshed with the pinion 1a of the seconds wheel set 12. The memorization wheel set M1 comprises a wheel M1a' which meshes with the wheel 1a' of the wheel set 12' on which is mounted or of which the member S′ for indicating the stored seconds, in particular on which the storage hand S′ is driven. This wheel M1a' is also integral with a plate MP1 on which an elastic return lever ML1 pivots. The wheel M1a' and the plate MP1 are advantageously fixed one on the other. The wheel 1a' and the display member S' of the stored seconds are connected by a shaft passing right through the frame B of the movement 2 of the timepiece 1, as shown in figure 5 .

En fonctionnement normal ou habituel, à savoir lorsque les organes d'affichage des secondes S et d'affichage des secondes mémorisées S' sont synchronisés comme sur les figures 1 et 7, la tête du levier de rappel ML1 est en appui à l'encontre d'épaulements, ou creux, ou plat, formés sur le profil de came MC10. Dans cette configuration, une came de commande C1, notamment une roue à colonnes, est positionnée de façon à ce qu'un dispositif de blocage B1 du plateau MP1 soit désactivé.In normal or usual operation, namely when the seconds display members S and the stored seconds display members S' are synchronized as on the figure 1 and 7 , the head of the return lever ML1 bears against shoulders, or hollow, or flat, formed on the cam profile MC10. In this configuration, a control cam C1, in particular a column wheel, is positioned so that a locking device B1 of the plate MP1 is deactivated.

Dans cette configuration, le dispositif de blocage n'a pas de prise sur le plateau MP1 et donc sur le mobile de mémorisation M1. Ainsi, l'action du levier de rappel ML1 sur la came MC10 entraîne la rotation synchrone du plateau MP1 et de la came MC10 et donc un affichage identique pour l'organe des secondes et l'organe des secondes mémorisées. Le mécanisme 3 comprend la came C1 de commande du premier dispositif de mémorisation.In this configuration, the blocking device has no grip on the plate MP1 and therefore on the mobile storage M1. Thus, the action of the return lever ML1 on the cam MC10 causes the synchronous rotation of the plate MP1 and of the cam MC10 and therefore an identical display for the seconds member and the stored seconds member. Mechanism 3 includes cam C1 for controlling the first storage device.

Le dispositif de blocage B1 comprend au moins un levier ou pince, préférentiellement deux leviers ou pinces P1 et P10, et un ressort R1. Les éléments sont agencés de sorte que le ressort ait tendance à rappeler les pinces à distance du plateau MP1 et donc à ne pas immobiliser le plateau MP1 (comme représenté à la figure 8). Les colonnes de la roue à colonnes et un palpeur LP1 sont agencés pour provoquer le contact des pinces P1 et P10 contre le plateau MP1 lorsque le palpeur LP1 est en appui sur une colonne de la roue (comme représenté à la figure 9). Le mécanisme d'affichage et de mémorisation comprend le dispositif de blocage B1.The blocking device B1 comprises at least one lever or clamp, preferably two levers or clamps P1 and P10, and a spring R1. The elements are arranged so that the spring tends to pull the clamps away from the MP1 plate and therefore does not immobilize the MP1 plate (as shown in figure 8 ). The columns of the column wheel and a feeler LP1 are arranged to cause the contact of the clamps P1 and P10 against the plate MP1 when the feeler LP1 is resting on a column of the wheel (as shown in figure 9 ). The display and memorization mechanism comprises the blocking device B1.

Avantageusement, la came de commande C1 se présente sous la forme d'une roue à colonnes qui est indexée angulairement par un ressort R. Celle-ci est par exemple pourvue d'un profil binaire C1a qui est constitué de colonnes et de creux. Dans la configuration de la figure 8, le palpeur LP1 de la pince P1 se situe en regard de l'un des creux du profil C1a de façon à ce que le ressort R1 positionne les pinces P1 et P10 hors de portée du plateau MP1 sur lequel pivote le levier de rappel élastique ML1 qui est prévu pour coopérer avec la came MC10.Advantageously, the control cam C1 is in the form of a column wheel which is angularly indexed by a spring R. This is for example provided with a binary profile C1a which consists of columns and hollows. In the configuration of the figure 8 , the feeler LP1 of the gripper P1 is located opposite one of the recesses of the profile C1a so that the spring R1 positions the grippers P1 and P10 out of reach of the plate MP1 on which the elastic return lever ML1 pivots which is intended to cooperate with the MC10 cam.

La came de commande C1 peut être également dotée d'une denture à rochet C1b qui est prévue pour être actionnée et entraînée d'un pas angulaire par un levier L sous l'effet d'un organe de commande O. Une pression sur ce dernier induit la rotation de la came de commande C1 de sorte à ce que l'une des colonnes du profil C1a entraîne les pinces P1, P10 à l'encontre du ressort R1 afin qu'elles puissent immobiliser en rotation le plateau MP1 du mobile M1. Ainsi, dans cette configuration (représentée à la figure 9), le levier ML1 est bloqué dans une position angulaire bien définie du plateau MP1, alors que la came MC10 poursuit sa rotation. Cette situation se traduit par une immobilisation de l'organe d'affichage des secondes mémorisées S', alors que l'organe d'affichage des secondes S poursuit sa course. Une nouvelle action sur l'organe de commande O positionne la came de commande C1 dans une configuration analogue à celle de la figure 9; la tête du levier ML1, sous l'effet de son élément de rappel élastique, se repositionne alors à l'encontre des épaulements, ou des creux, ou du plat, de la came MC10. Ainsi, l'organe d'affichage des secondes S et l'organe d'affichage des secondes mémorisées S' sont à nouveau synchronisés. Le mécanisme 3 comprend l'organe de commande O. Cet organe de commande permet d'agir sur les cames de commande C1, C2.The control cam C1 can also be provided with a ratchet toothing C1b which is provided to be actuated and driven with an angular pitch by a lever L under the effect of a control member O. A pressure on the latter induces the rotation of the control cam C1 so that one of the columns of the profile C1a drives the clamps P1, P10 against the spring R1 so that they can immobilize the plate MP1 in rotation of mobile M1. Thus, in this configuration (shown in figure 9 ), the lever ML1 is locked in a well-defined angular position of the plate MP1, while the cam MC10 continues to rotate. This situation results in immobilization of the stored seconds display member S′, while the seconds display member S continues its course. A new action on the control member O positions the control cam C1 in a configuration similar to that of the figure 9 ; the head of the lever ML1, under the effect of its elastic return element, is then repositioned against the shoulders, or the recesses, or the flat, of the cam MC10. Thus, the seconds display member S and the stored seconds display member S′ are again synchronized. The mechanism 3 includes the control member O. This control member makes it possible to act on the control cams C1, C2.

Le deuxième dispositif de mémorisation MEM2 réalise une interface entre les organes H, M d'affichage des heures et minutes et les organes H' et M' d'affichage des heures et minutes mémorisées.The second storage device MEM2 provides an interface between the hours and minutes display units H, M and the stored hours and minutes display units H' and M'.

Le deuxième dispositif de mémorisation MEM2 est décrit ci-après en référence aux figures 10 à 17. Le deuxième dispositif de mémorisation comprend :

  • un deuxième mobile M2 de mémorisation doté d'un deuxième élément MC2 de mémorisation destiné à être en prise avec une chaîne cinématique 16 qui est dédiée au dit mobile.
The second storage device MEM2 is described below with reference to the figures 10 to 17 . The second storage device comprises:
  • a second storage mobile M2 provided with a second storage element MC2 intended to engage with a kinematic chain 16 which is dedicated to said mobile.

Plus précisément, le deuxième dispositif de mémorisation comprend, outre le deuxième mobile M2, une minuterie auxiliaire liant l'organe H' d'affichage des heures mémorisées et l'organe M' d'affichage des minutes mémorisées, notamment en engrènement, avec le deuxième mobile M2 de mémorisation.More specifically, the second storage device comprises, in addition to the second mobile M2, an auxiliary timer linking the member H' for displaying the stored hours and the member M' for displaying the stored minutes, in particular in mesh, with the second mobile M2 for storing.

Plus précisément, le deuxième mobile de mémorisation M2 comprend une roue M2a sur laquelle est monté ou fixé le deuxième élément de mémorisation comprenant par exemple une came MC20, notamment une came en forme de cœur. Cette roue M2a peut être continuellement engrenée avec une roue des heures 162 qui porte l'organe H d'affichage des heures. Le mobile de mémorisation M2 comprend une roue M2a' qui est en prise avec une roue 162a' solidaire de la roue 162' qui porte l'organe H' d'affichage des heures mémorisées. Cette roue M2a' est également solidaire d'un plateau MP2 sur lequel pivote un levier de rappel élastique ML2. La roue M2a' et le plateau MP2 sont avantageusement fixés l'un sur l'autre.More precisely, the second storage mobile M2 comprises a wheel M2a on which is mounted or fixed the second storage element comprising for example a cam MC20, in particular a heart-shaped cam. This wheel M2a can be continuously meshed with an hour wheel 162 which carries the hour display member H. The storage mobile M2 comprises a wheel M2a' which meshes with a wheel 162a' integral with the wheel 162' which carries the member H' for displaying the stored hours. This wheel M2a' is also integral with a plate MP2 on which an elastic return lever ML2 pivots. The wheel M2a' and the plate MP2 are advantageously fixed one on the other.

Le deuxième dispositif de mémorisation est similaire au premier dispositif de mémorisation. Ainsi, les organes H et M d'affichage des heures et des minutes sont liés aux organes H' et M' d'affichage des heures et des minutes mémorisées par l'entremise du deuxième mobile de mémorisation M2.The second storage device is similar to the first storage device. Thus, the members H and M for displaying the hours and minutes are linked to the members H' and M' for displaying the hours and minutes stored by means of the second storage mobile M2.

Avantageusement, le deuxième mobile de mémorisation M2 est disposé du côté du bâti du mouvement opposé à celui où est disposé le premier mobile de mémorisation M1 comme représenté sur les figures 5, 11, 12.Advantageously, the second memory mobile M2 is arranged on the side of the frame of the movement opposite to that on which the first memory mobile M1 is arranged as shown in the figure 5 , 11 , 12 .

La structure du deuxième mobile de mémorisation M2 est analogue à celle du mobile de M1. Le deuxième mobile M2 comprend une roue M2a sur laquelle est montée une came MC20, notamment une came en forme de cœur. Cette roue M2a est en prise, notamment continuellement en prise, avec une roue des heures 162 sur laquelle est monté l'organe H d'affichage des heures, notamment sur laquelle est chassée une aiguille des heures H. Le deuxième mobile M2 comprend aussi une roue M2a' qui entraîne la roue des heures de mémorisation 162' par le biais d'une planche de roue 162a' qui est montée sur cette dernière. La liaison cinématique entre la roue des heures mémorisée 162', sur laquelle est monté l'organe d'affichage des heures mémorisées, notamment sur laquelle est chassée une aiguille H', et la chaussée 164', solidaire de l'organe d'affichage des minutes mémorisées M', s'effectue, quant-à elle, par l'intermédiaire de la minuterie auxiliaire 16' dont la structure est identique à celle de la minuterie 16.The structure of the second storage mobile M2 is similar to that of the mobile of M1. The second mobile M2 comprises a wheel M2a on which is mounted a cam MC20, in particular a heart-shaped cam. This wheel M2a is in mesh, in particular continuously in mesh, with an hour wheel 162 on which the member H is mounted. hour display, in particular on which an hour hand H is driven. The second mobile M2 also comprises a wheel M2a' which drives the storage hour wheel 162' by means of a wheel plate 162a' which is mounted on it. The kinematic connection between the memorized hours wheel 162', on which the memorized hours display member is mounted, in particular on which a hand H' is driven, and the roadway 164', integral with the display member memorized minutes M', is carried out, for its part, via the auxiliary timer 16', the structure of which is identical to that of the timer 16.

Un dispositif de blocage B2 est dédié au mobile de mémoire M2. Le dispositif de blocage B2 est semblable au dispositif de blocage B1. Tout comme le dispositif de blocage B1, le dispositif de blocage B2 comprend au moins un levier ou pince, préférentiellement deux leviers ou pinces P2 et P20 et un ressort R2. Ce dispositif de blocage est également piloté par une came de commande C2, par exemple une roue à colonnes. Le mécanisme d'affichage et de mémorisation comprend le dispositif de blocage B2. Le mécanisme 3 comprend la came C2 de commande du deuxième dispositif de mémorisation.A blocking device B2 is dedicated to the memory mobile M2. Blocking device B2 is similar to blocking device B1.

This blocking device is also controlled by a control cam C2, for example a column wheel. The display and memorization mechanism comprises the blocking device B2. Mechanism 3 includes cam C2 for controlling the second storage device.

De façon à synchroniser le pilotage des organes H' et M' d'affichage des heures et des minutes mémorisées et de l'organe S' d'affichage des secondes mémorisées, la came de commande C2 présente la particularité d'être solidaire en rotation de la came de commande C1 par le biais d'un arbre A qui traverse de part en part le bâti B du mouvement 2 de la pièce d'horlogerie 1, comme représenté à la figure 14. Préférentiellement, une géométrie GA de l'arbre A est prévue pour coopérer avec une géométrie GC2 complémentaire ou sensiblement complémentaire de la came de commande C2 afin de faciliter l'indexation angulaire de la came de commande C2 relativement à la came de commande C1. Ainsi, la première came de commande C1 et la deuxième came de commande C2 sont reliées par un arbre A.In order to synchronize the control of the members H' and M' for displaying the stored hours and minutes and of the member S' for displaying the stored seconds, the control cam C2 has the particularity of being integral in rotation of the control cam C1 by means of a shaft A which passes right through the frame B of the movement 2 of the timepiece 1, as shown in figure 14 . Preferably, a geometry GA of the shaft A is provided to cooperate with a geometry GC2 complementary or substantially complementary to the control cam C2 in order to facilitate the angular indexing of the control cam C2 relative to the cam of command C1. Thus, the first control cam C1 and the second control cam C2 are connected by a shaft A.

Dans la configuration de la figure 13, la came de commande C2 est positionnée de façon à ce que le dispositif de blocage B2 n'ait pas de prise sur le mobile de mémorisation M2. Plus particulièrement, une extrémité d'un bras LP2 de la pince P2 se situe en regard de l'un des creux du profil C2a de façon à ce que le ressort R2 positionne les pinces P2 et P20 hors de portée du plateau MP2. Ainsi, la tête du levier de rappel ML2 est en appui continu à l'encontre des épaulements, ou du creux, ou du plat formé sur le profil de la came MC20, ce qui se traduit par une synchronisation du jeu des organes H' et M' d'affichage des heures et des minutes mémorisées et du jeu des organes H et M d'affichage des heures et des minutes.In the configuration of the figure 13 , the control cam C2 is positioned so that the blocking device B2 has no grip on the mobile storage M2. More specifically, one end of an arm LP2 of the clamp P2 is located opposite one of the recesses of the profile C2a so that the spring R2 positions the clamps P2 and P20 out of reach of the plate MP2. Thus, the head of the return lever ML2 is in continuous support against the shoulders, or the hollow, or the flat formed on the profile of the cam MC20, which results in a synchronization of the play of the organs H 'and M' for displaying the stored hours and minutes and the set of organs H and M for displaying the hours and minutes.

La configuration illustrée aux figures 13 et 15 coïncide avec celle illustrée par la figure 8. Autrement dit, lorsque la pince P2 se situe en regard de l'un des creux du profil C2a de la came de commande C2, la pince P1 se situe également en regard de l'un des creux du profil C1a de la came de commande C1. Les dispositifs de blocage B1 et B2 sont ainsi synchronisés, ce qui se traduit par une synchronisation de l'immobilisation des organes d'affichage des heures, minutes et secondes mémorisées.The configuration illustrated in figure 13 and 15 coincides with that illustrated by the figure 8 . In other words, when the clamp P2 is located opposite one of the hollows of the profile C2a of the control cam C2, the clamp P1 is also located opposite one of the hollows of the profile C1a of the control cam C1 . The blocking devices B1 and B2 are thus synchronized, which results in synchronization of the immobilization of the display members of the stored hours, minutes and seconds.

A l'instar de la came de commande C1, une action sur l'organe de commande O induit la rotation de la came de commande C2 de sorte à ce que l'une des colonnes du profil C2a entraîne les pinces P2 et P20 à l'encontre du ressort R2 afin qu'elles puissent immobiliser en rotation le plateau MP2 du mobile M2. Ainsi, dans la configuration des figures 16 et 17, le levier ML2 est bloqué dans une position angulaire bien définie du plateau MP2, alors que la came MC20 poursuit sa rotation. Cette situation se traduit par une immobilisation les organes H' et M' d'affichage des heures et des minutes mémorisées alors que les organes H et M d'affichage des heures et des minutes poursuit sa course.Like the control cam C1, an action on the control member O induces the rotation of the control cam C2 so that one of the columns of the profile C2a drives the clamps P2 and P20 to the against the spring R2 so that they can immobilize in rotation the plate MP2 of the mobile M2. Thus, in the configuration of figure 16 and 17 , the lever ML2 is locked in a well-defined angular position of the plate MP2, while the cam MC20 continues to rotate. This This situation results in immobilization of the members H' and M' for displaying the stored hours and minutes while the members H and M for displaying the hours and minutes continue their course.

Cette configuration illustrée par les figures 16 et 17 coïncide avec celle illustrée par la figure 9. Autrement dit, lorsque la pince P2 se situe en regard de l'une des colonnes du profil C2a de la came de commande C2, la pince P1 se situe également en regard de l'une des colonnes du profil C1a de la came C1. Les dispositifs de blocage B1 et B2 sont ainsi synchronisés, ce qui se traduit par une synchronisation de l'arrêt des organes H', M' et S' d'affichage des heures, des minutes et des secondes mémorisées.This configuration illustrated by the figure 16 and 17 coincides with that illustrated by the figure 9 . In other words, when the gripper P2 is located opposite one of the columns of the profile C2a of the control cam C2, the gripper P1 is also situated opposite one of the columns of the profile C1a of the cam C1. The blocking devices B1 and B2 are thus synchronized, which results in a synchronization of the stopping of the members H′, M′ and S′ for displaying the stored hours, minutes and seconds.

Bien entendu, les profils C1a, C2a des cames respectives C1, C2 peuvent être conformés différemment si les dispositifs de blocages B1, B2 présentent des modes de fonctionnement distincts. Dans tous les cas de figure, les cames C1 et C2 sont définies de façon à synchroniser les dispositifs de blocage B1, B2 en vue de synchroniser l'arrêt des organes H', M' et S' d'affichage des heures, des minutes et des secondes mémorisées.Of course, the profiles C1a, C2a of the respective cams C1, C2 can be shaped differently if the blocking devices B1, B2 have distinct operating modes. In all cases, the cams C1 and C2 are defined so as to synchronize the blocking devices B1, B2 with a view to synchronizing the stopping of the organs H', M' and S' for displaying the hours, minutes and memorized seconds.

Grâce à l'invention, le premier mobile de mémorisation M1 est en prise directe avec le mobile des secondes du rouage de finissage. Ce mobile de mémorisation est commandé par le premier dispositif de blocage B1.Thanks to the invention, the first storage mobile M1 is in direct contact with the mobile for the seconds of the going train. This storage mobile is controlled by the first blocking device B1.

Le deuxième mobile de mémorisation M2 permet la mémorisation des heures et/ou des minutes. Il est en prise directe avec la minuterie du mouvement de base. Ce mobile de mémorisation est commandé par au moins un deuxième dispositif de blocage B2.The second storage mobile M2 allows the storage of hours and/or minutes. It is in direct contact with the basic movement timer. This storage mobile is controlled by at least one second blocking device B2.

Les cames de commande C1, C2 sont prévues pour piloter chacun des dispositifs de blocage B1, B2. Elles sont actionnées par l'intermédiaire de l'organe de commande O qui transmet les actions que l'utilisateur exerce sur le mécanisme d'affichage et de mémorisation 3, sur le mouvement 2 ou sur la pièce d'horlogerie 1.The control cams C1, C2 are provided to drive each of the blocking devices B1, B2. They are actuated via the control member O which transmits the actions that the user exerts on the display and memorization mechanism 3, on the movement 2 or on the timepiece 1.

Les cames de commande C1, C2 sont mobiles en rotation. Elles sont conformées pour être disposées de part et d'autre du bâti B de la pièce d'horlogerie 1 de façon à piloter les au moins deux dispositifs de blocage B1, B2.The control cams C1, C2 are movable in rotation. They are shaped to be arranged on either side of the frame B of the timepiece 1 so as to drive the at least two blocking devices B1, B2.

Le mobile des secondes 12 est par exemple disposé d'un premier côté du bâti B du mouvement, tandis que la minuterie est classiquement disposée de l'autre côté du bâti du mouvement comme représenté sur la figure 11.The seconds mobile 12 is for example arranged on a first side of the frame B of the movement, while the timer is conventionally arranged on the other side of the frame of the movement as shown in the figure 11 .

Comme représenté à la figure 11, le mécanisme 3 présente un plan médian P3 parallèle au plan PB du bâti B du mouvement. Le plan médian P3 est sensiblement perpendiculaire à l'arbre A et au mobile 12' et partage l'espace en deux parties de même volume dans lesquelles est contenu intégralement le mécanisme 3. Le plan PB du bâti sépare la platine du mouvement en une première partie et une deuxième partie d'encombrements sensiblement égaux. Le premier dispositif de mémorisation MEM1, en particulier le mobile de mémorisation M1 et/ou le premier élément MC1 de mémorisation et/ou le plateau MP1, se trouve dans la première partie. Le deuxième dispositif de mémorisation MEM2, en particulier le mobile de mémorisation M2 et/ou le premier élément MC2 de mémorisation et/ou le plateau MP2, se trouve dans la deuxième partie.As depicted at figure 11 , the mechanism 3 has a median plane P3 parallel to the plane PB of the frame B of the movement. The median plane P3 is substantially perpendicular to the shaft A and to the mobile 12' and divides the space into two parts of the same volume in which the mechanism 3 is entirely contained. The plane PB of the frame separates the plate from the movement into a first part and a second part of substantially equal dimensions. The first storage device MEM1, in particular the storage mobile M1 and/or the first storage element MC1 and/or the tray MP1, is located in the first part. The second storage device MEM2, in particular the storage mobile M2 and/or the first storage element MC2 and/or the tray MP2, is located in the second part.

Le mécanisme d'affichage et de mémorisation comprend des organes d'affichage du temps et de mémorisation d'un instant se situant préférentiellement dans une plage de 12 heures, voire de 24 heures. Préférentiellement, les organes d'affichage du temps et les organes de mémorisation se déplacent au même rythme sur une même plage horaire. Alternativement, les aiguilles d'affichage du temps et celles de mémorisation indiquent les informations sur deux plages temporelles distinctes.The display and memorization mechanism comprises members for displaying the time and for memorizing a moment preferably lying within a range of 12 hours, or even 24 hours. Preferably, the time display members and the storage members move at the same rate over the same time slot. Alternatively, the time display hands and the memorization hands indicate the information on two separate time ranges.

Ainsi, selon l'invention, pour chacune des informations temporelles ou horaires, heures et/ou minutes et/ou secondes, le mécanisme présente la spécificité d'indiquer sélectivement l'information mémorisée ou l'information courante par un même organe d'affichage sous l'actionnement d'un unique organe de commande. Un tel mécanisme peut par exemple être utile pour marquer l'horaire de début d'un événement et en indiquer l'horaire de fin à la seconde près.Thus, according to the invention, for each of the time or time information, hours and/or minutes and/or seconds, the mechanism has the specificity of selectively indicating the stored information or the current information by the same display device under the actuation of a single control device. Such a mechanism can for example be useful for marking the start time of an event and indicating its end time to the nearest second.

Un positionnement d'organes d'affichage dans une ou plusieurs positions aléatoires ou définies une fois pour toutes, c'est-à-dire dans une ou plusieurs positions non définissables ou non modifiables par l'utilisateur, comme on peut trouver dans des mécanismes d'affichage à la demande, ne constitue pas une mémorisation au sens de l'invention.A positioning of display members in one or more random positions or defined once and for all, that is to say in one or more positions that cannot be defined or can be modified by the user, such as can be found in mechanisms display on demand, does not constitute a storage within the meaning of the invention.

Dans tout ce document, par « prise directe », nous entendons toute liaison cinématique dénuée de dispositif d'embrayage. De préférence, la liaison est donc permanente. Eventuellement, un ou plusieurs éléments intermédiaires peuvent être disposés entre la roue des secondes et le mobile de mémorisation.Throughout this document, by "direct drive", we mean any kinematic connection devoid of a clutch device. Preferably, the connection is therefore permanent. Optionally, one or more intermediate elements may be arranged between the seconds wheel and the memorization wheel set.
