Definitions

  • the invention relates to a system for locking at least one control element of a timepiece. It also relates to a watch case comprising such a system. Finally, it relates to a timepiece, in particular a wristwatch, comprising such a system or such a case.

  • a push button capable of being screwed against a ring so as to secure it in position, and thus avoid any untimely activation of a watch function driven by said push button.
  • activation and deactivation devices for a push button as there are push buttons fitted to a timepiece.
  • devices are also proposed allowing, in a single operation, the synchronized activation or deactivation of at least two push buttons. Nevertheless, such devices are not optimal and can in particular compromise the functional or aesthetic integrity of the timepiece.
  • the patent CH423638 relates to a specific construction of waterproof and screwed push button.
  • a threaded and screwed ring on the pusher is capable of occupying two positions, one, of rest, in which it allows said pusher to be actuated, and the other in which it bears on a part of the box of the timepiece, so as to exert an axial traction on the pusher having the effect, on the one hand, of compressing a seal interposed between said pusher and the element of the case through which it passes, and on the other hand to block the pusher.
  • the patent application CH704262 discloses a device allowing the synchronized blocking of a crown and at least one push button. Such a device is controlled by a ring arranged concentrically to said crown. The handling of such a ring can prove tricky, in particular when the latter has to be actuated under water on the occasion, for example, of the practice of scuba diving.
  • the patent application EP2399172 relates to an internal blocking device for push buttons of a wristwatch.
  • the push buttons can be activated or deactivated in a synchronized manner by means of a crown, which is provided for winding and adjusting the wristwatch.
  • the unscrewing/rescrewing of said crown induces the unlocking/locking of the push buttons by means of a mechanism internal to the case.
  • Such a design cannot be suitable with regard to predefined tightness criteria, in particular if the push buttons have to be manipulated in a marine environment.
  • the push buttons can be activated or deactivated in a synchronized manner by means of a rotating bezel.

Néanmoins, des tels dispositifs ne sont pas optimaux et peuvent notamment prétériter l'intégrité fonctionnelle ou esthétique de la pièce d'horlogerie.It is, for example, known to propose a push button capable of being screwed against a ring so as to secure it in position, and thus avoid any untimely activation of a watch function driven by said push button. There are thus as many activation and deactivation devices for a push button as there are push buttons fitted to a timepiece. With the aim of improving handling when worn, devices are also proposed allowing, in a single operation, the synchronized activation or deactivation of at least two push buttons. Nevertheless, such devices are not optimal and can in particular compromise the functional or aesthetic integrity of the timepiece.

Le brevet CH423638 concerne une construction spécifique de bouton poussoir étanche et vissé. Une bague taraudée et vissée sur le poussoir, est susceptible d'occuper deux positions, l'une, de repos, dans laquelle elle permet audit poussoir d'être actionné, et l'autre dans laquelle elle prend appui sur une partie de la boîte de la pièce d'horlogerie, de manière à exercer sur le poussoir une traction axiale ayant pour effet d'une part de comprimer une garniture d'étanchéité interposée entre ledit poussoir et l'élément de la boîte traversé par celui-ci, et d'autre part de bloquer le poussoir.The patent CH423638 relates to a specific construction of waterproof and screwed push button. A threaded and screwed ring on the pusher, is capable of occupying two positions, one, of rest, in which it allows said pusher to be actuated, and the other in which it bears on a part of the box of the timepiece, so as to exert an axial traction on the pusher having the effect, on the one hand, of compressing a seal interposed between said pusher and the element of the case through which it passes, and on the other hand to block the pusher.

La demande de brevet CH704262 divulgue un dispositif permettant le blocage synchronisé d'une couronne et d'au moins un bouton poussoir. Un tel dispositif est commandé par une bague disposée concentriquement à ladite couronne. Les manipulations d'une telle bague peuvent s'avérer délicates, notamment lorsque celle-ci doit être actionnée sous l'eau à l'occasion, par exemple, de la pratique de la plongée sous-marine.The patent application CH704262 discloses a device allowing the synchronized blocking of a crown and at least one push button. Such a device is controlled by a ring arranged concentrically to said crown. The handling of such a ring can prove tricky, in particular when the latter has to be actuated under water on the occasion, for example, of the practice of scuba diving.

La demande de brevet EP2399172 concerne un dispositif de blocage interne pour boutons poussoirs d'une montre bracelet. Selon un premier mode de réalisation, les boutons poussoirs peuvent être activés ou désactivés de manière synchronisée par le biais d'une couronne, qui est prévue pour le remontage et le réglage de la montre-bracelet. Le dévissage/revissage de ladite couronne induit le déverrouillage/verrouillage des boutons poussoirs par le biais d'un mécanisme interne à la boîte. Une telle conception ne peut convenir en regard de critères d'étanchéité prédéfinis, en particulier si les boutons poussoirs doivent être manipulés en milieu marin. Selon un deuxième mode de réalisation, les boutons poussoirs peuvent être activés ou désactivés de manière synchronisée par le biais d'une lunette mobile en rotation. Une telle conception requiert des garnitures d'étanchéité additionnelles pour permettre l'actionnement du mécanisme interne à la boîte et n'est donc pas optimale en regard des critères précités. Par ailleurs, une telle solution n'est pas optimale pour une lunette graduée prévue pour fournir une autre fonction ou une indication telle qu'une information horaire ou dérivée de l'heure.The patent application EP2399172 relates to an internal blocking device for push buttons of a wristwatch. According to a first embodiment, the push buttons can be activated or deactivated in a synchronized manner by means of a crown, which is provided for winding and adjusting the wristwatch. The unscrewing/rescrewing of said crown induces the unlocking/locking of the push buttons by means of a mechanism internal to the case. Such a design cannot be suitable with regard to predefined tightness criteria, in particular if the push buttons have to be manipulated in a marine environment. According to a second embodiment, the push buttons can be activated or deactivated in a synchronized manner by means of a rotating bezel. Such a design requires additional seals to allow actuation of the mechanism internal to the box and is therefore not optimal with regard to the aforementioned criteria. Furthermore, such a solution is not optimal for a graduated bezel provided to provide another function or an indication such as time information or information derived from the time.

La demande de brevet CH700535 se rapporte à une lunette rotative de géométrie asymétrique qui est, pour une position angulaire prédéfinie, prévue pour masquer une couronne de remontage et/ou de réglage d'une pièce d'horlogerie de façon à éviter toute manipulation intempestive. Une telle solution n'est pas optimale pour une lunette graduée prévue pour fournir une autre fonction ou une indication telle qu'une information horaire ou dérivée de l'heure. Par ailleurs, l'organe masqué n'est pas parfaitement sécurisé étant donné qu'il peut être intempestivement activé depuis le côté « sous » de la boîte de montre.The patent application CH700535 relates to a rotating bezel of asymmetrical geometry which is, for a predefined angular position, designed to hide a crown for winding and/or adjusting a timepiece so as to avoid any inadvertent manipulation. Such a solution is not optimal for a graduated bezel provided to provide another function or an indication such as time information or information derived from the time. Furthermore, the masked member is not perfectly secure given that it can be inopportunely activated from the “under” side of the watch case.

La demande de brevet JP2005337792 concerne une lunette tournante qui est prévue, dans une position angulaire prédéfinie, pour s'interposer avec des boutons poussoirs de façon à bloquer leur translation. Plus particulièrement, un flanc venu de matière avec la lunette peut être conformé pour venir se loger au sein de gorges formées sur chacun des boutons poussoirs de façon à constituer un dispositif d'activation et de désactivation externe à la boîte de montre. L'état de ce dispositif est ici fourni par des marquages disposés sur la lunette tournante. Une telle solution n'est donc pas optimale pour une lunette graduée prévue pour fournir une autre fonction ou une indication telle qu'une information horaire ou dérivée de l'heure.The patent application JP2005337792 relates to a rotating bezel which is provided, in a predefined angular position, to interpose with push buttons so as to block their translation. More particularly, a flank made in one piece with the bezel can be shaped to be housed within grooves formed on each of the push buttons so as to constitute an activation and deactivation device external to the watch case. The state of this device is provided here by markings arranged on the rotating bezel. Such a solution is therefore not optimal for a graduated bezel provided to provide another function or an indication such as time information or information derived from the time.

La demande de brevet US20100128575 divulgue un dispositif similaire à celui du document JP2005337792 . Une lunette tournante agit sur des boutons poussoirs par le biais d'un élément de verrouillage qui lui est concentrique. Cet élément de verrouillage prend la forme d'une rondelle qui comporte des portions déformables élastiquement de sorte à ce qu'elles puissent s'interposer à la translation des boutons poussoirs. A l'instar de la demande JP2005337792 , l'état du dispositif est fourni par des marquages disposés sur la lunette tournante. Une telle solution n'est donc pas optimale pour une lunette graduée prévue pour fournir une autre fonction ou une indication telle qu'une information horaire ou dérivée de l'heure.The patent application US20100128575 discloses a device similar to that of the document JP2005337792 . A rotating bezel acts on push buttons via a locking element which is concentric with it. This locking element takes the form of a washer which comprises elastically deformable portions so that they can intervene in the translation of the push buttons. As requested JP2005337792 , the state of the device is provided by markings arranged on the rotating bezel. Such a solution is therefore not optimal for a graduated telescope intended to provide a other function or an indication such as time or time-derived information.

Le but de l'invention est de fournir un système de verrouillage permettant de remédier aux inconvénients mentionnés précédemment et d'améliorer les systèmes de verrouillage connus de l'art antérieur. En particulier, l'invention propose un système de verrouillage compact, fiable et impactant au minimum l'esthétique et les fonctionnalités de la pièce d'horlogerie.The object of the invention is to provide a locking system making it possible to remedy the aforementioned drawbacks and to improve the locking systems known from the prior art. In particular, the invention proposes a locking system that is compact, reliable and has a minimum impact on the aesthetics and functionality of the timepiece.

Une boîte de montre selon l'invention est définie par la revendication 1. Différents modes de réalisation de boîtes de montres sont définis par les revendications dépendantes 2 à 13.A watch case according to the invention is defined by claim 1. Different embodiments of watch cases are defined by dependent claims 2 to 13.

Une pièce d'horlogerie selon l'invention est définie par la revendication 14.A timepiece according to the invention is defined by claim 14.

Les figures annexées représentent à titre d'exemples plusieurs modes de réalisation d'une pièce d'horlogerie intégrant un système de verrouillage. Les figures 1 à 8 représentent un premier mode de réalisation d'une pièce d'horlogerie.The appended figures show, by way of example, several embodiments of a timepiece incorporating a locking system. The figures 1 to 8 represent a first embodiment of a timepiece.

La figure 9 représente un deuxième mode de réalisation d'une pièce d'horlogerie.The figure 9 represents a second embodiment of a timepiece.

La figure 10 est une vue en coupe d'une pièce d'horlogerie selon le premier mode de réalisation avec plusieurs garnitures d'étanchéité de la boîte représentées.The figure 10 is a sectional view of a timepiece according to the first embodiment with several seals of the case shown.

Un premier mode de réalisation d'une pièce d'horlogerie 200 est décrit ci-après en référence aux figures 1 à 8 et 10. La pièce d'horlogerie est par exemple une montre, notamment une montre bracelet. La pièce d'horlogerie comprend une boîte de montre 150 et un mouvement horloger (non représenté). Le mouvement peut être du type électronique ou du type mécanique. Par exemple, le mouvement peut être mécanique et automatique.A first embodiment of a timepiece 200 is described below with reference to the figures 1 to 8 and 10 . The timepiece is for example a watch, in particular a wristwatch. The timepiece includes a watch case 150 and a watch movement (not shown). The movement can be of the electronic type or of the mechanical type. For example, the movement can be mechanical and automatic.

La boîte de montre permet d'enfermer et de protéger le mouvement horloger, notamment de le protéger de l'environnement dans lequel se trouve la pièce d'horlogerie. Ainsi, la boîte de montre constitue une chambre 63 ou une enveloppe, de préférence une chambre ou une enveloppe étanche, destinée à recevoir le mouvement horloger. Le degré d'étanchéité réalisée par la boîte peut être plus ou moins élevé en fonction de la construction et des garnitures d'étanchéité employées.The watch case makes it possible to enclose and protect the watch movement, in particular to protect it from the environment in which the timepiece is located. Thus, the watch case constitutes a chamber 63 or an envelope, preferably a sealed chamber or envelope, intended to receive the watch movement. The degree of tightness achieved by the box can be higher or lower depending on the construction and the seals used.

La boîte de montre peut principalement comprendre une carrure 6, un fond 61, une lunette 5 et une glace 62. De préférence, la lunette est une lunette fixe, soit une lunette immobilisée sur la carrure. La lunette 5 peut, par exemple, être graduée et/ou comporter des indications, notamment des indications horaires ou dérivées de l'heure. De préférence, ces indications ne sont pas des indications d'état de verrouillage ou de déverrouillage d'éléments de commande.The watch case can mainly comprise a middle 6, a back 61, a bezel 5 and a crystal 62. Preferably, the bezel is a fixed bezel, ie a bezel immobilized on the middle. The bezel 5 can, for example, be graduated and/or comprise indications, in particular time indications or indications derived from time. Preferably, these indications are not indications of the locking or unlocking state of control elements.

La boîte comprend en outre un ou plusieurs éléments de commande 1, 7. Les éléments de commande sont agencés de sorte que le porteur de la montre puisse agir sur ceux-ci, notamment les translater et/ou les tourner de sorte à transmettre des actions et des déplacements au mouvement horloger se trouvant dans la boîte de montre. Dans le mode de réalisation représenté, les éléments de commande sont une couronne 7 et deux boutons poussoirs 1 ou poussoirs 1. Les éléments de commande pourraient être de nombres et/ou de natures différents. Notamment, l'au moins un élément de commande pourrait comprendre un verrou ou un levier.The case further comprises one or more control elements 1, 7. The control elements are arranged so that the wearer of the watch can act on them, in particular to translate them and/or turn them so as to transmit actions and displacements to the watch movement located in the watch case. In the embodiment represented, the control elements are a crown 7 and two push-buttons 1 or push-buttons 1. The control elements could be of different numbers and/or types. In particular, the at least one control element could comprise a lock or a lever.

Les éléments de commande sont utilisés pour effectuer différentes actions de commande du mouvement, notamment des actions de remontage d'un ressort de barillet, des actions de correction de fonctions horlogères, des actions d'activation de fonctions horlogères, des actions de désactivation de fonctions horlogères ou des actions de remise en position prédéterminée de fonctions horlogères.The control elements are used to perform various movement control actions, in particular actions for winding a barrel spring, actions for correcting watch functions, actions for activating watch functions, actions for deactivating functions watchmaking or actions to reset watchmaking functions to a predetermined position.

Par exemple, dans le mode de réalisation représenté, les deux poussoirs permettent de commander un chronographe. Par exemple, un premier poussoir permet d'activer et de désactiver le chronographe et un deuxième poussoir permet de remettre à zéro le chronographe.For example, in the embodiment represented, the two push-buttons make it possible to control a chronograph. For example, a first pusher enables and deactivates the chronograph and a second pusher enables the chronograph to be reset.

Par exemple, dans le mode de réalisation représenté, la couronne permet notamment de remonter le mouvement et de corriger l'affichage de l'heure courante.For example, in the embodiment represented, the crown makes it possible in particular to wind the movement and to correct the display of the current time.

La boîte de montre comprend également un système de verrouillage 100 d'au moins un élément de commande 1.The watch case also includes a locking system 100 of at least one control element 1.

De préférence, le système de verrouillage se trouve ou est agencé à l'extérieur de l'enveloppe 63 ou de la chambre 63 définie par la boîte. Ainsi, de préférence, le système de verrouillage n'est pas visible depuis l'intérieur de la chambre définie par la boîte de montre. De préférence encore, le système de verrouillage est agencé quasi intégralement dans la carrure, c'est-à-dire dans l'épaisseur de la carrure, ou au plus proche de la carrure, à l'extérieur de celle-ci.Preferably, the locking system is located or is arranged outside the envelope 63 or the chamber 63 defined by the box. Thus, preferably, the locking system is not visible from inside the chamber defined by the watch case. Preferably again, the locking system is arranged almost entirely in the middle part, that is to say in the thickness of the middle part, or as close as possible to the middle part, outside the latter.

Le système 100 de verrouillage d'au moins un élément de commande 1 de la pièce d'horlogerie 200, comprend :

  • un élément manipulable 3,
  • un élément de verrouillage 2 de l'au moins un élément de commande,
  • une liaison cinématique 2a, 3a reliant l'élément manipulable à l'élément de verrouillage.
The system 100 for locking at least one control element 1 of the timepiece 200 comprises:
  • a manipulable element 3,
  • a locking element 2 of the at least one control element,
  • a kinematic link 2a, 3a connecting the manipulable element to the locking element.

Ainsi, le système de verrouillage comporte un élément de verrouillage qui est actionnable par le biais de l'élément manipulable 3.Thus, the locking system comprises a locking element which is operable through the manipulable element 3.

L'élément de verrouillage 2 permet selon son état ou sa position d'autoriser ou d'interdire l'actionnement de l'au moins un élément de commande.The locking element 2 makes it possible, depending on its state or its position, to authorize or prohibit the actuation of the at least one control element.

L'au moins un élément de commande 1 comprend de préférence au moins un poussoir 1 et/ou au moins une couronne 7. Dans le mode de réalisation décrit, l'au moins un élément de commande comprend deux poussoirs.The at least one control element 1 preferably comprises at least one pusher 1 and/or at least one crown 7. In the embodiment described, the at least one control element comprises two pushers.

De préférence, les deux poussoirs ont des structures identiques ou similaires. Ainsi, un seul élément de commande 1 de type poussoir est décrit en détail ci-après.Preferably, the two pushers have identical or similar structures. Thus, a single push-type control element 1 is described in detail below.

Avantageusement, l'élément de commande 1 est prévu au niveau de la carrure de la boîte et permet au porteur d'exercer une action sur le mouvement horloger au travers de cette carrure.Advantageously, the control element 1 is provided at the middle of the case and allows the wearer to exert an action on the watch movement through this middle.

De préférence, l'élément de commande 1 est monté mobile en translation selon un axe A1 relativement au reste de la boîte de montre, en particulier relativement à la carrure. Cet axe A1 est par exemple perpendiculaire à un axe A3 de la boîte de montre, c'est-à-dire l'axe A3 de révolution du cadran de montre (pour un cadran cylindrique ou sensiblement cylindrique) et/ou du mouvement (pour un mouvement cylindrique ou sensiblement cylindrique), lorsque le cadran et/ou le mouvement sont montés dans la boîte. L'axe A3 peut être l'axe de révolution des aiguilles. L'axe A3 peut également correspondre à l'axe de révolution de la lunette annulaire 5. De préférence, l'axe A1 est parallèle au cadran de la montre. De préférence, l'axe A3 est perpendiculaire au cadran de la montre.Preferably, the control element 1 is mounted to move in translation along an axis A1 relative to the rest of the watch case, in particular relative to the caseband. This axis A1 is for example perpendicular to an axis A3 of the watch case, that is to say the axis A3 of revolution of the watch dial (for a cylindrical or substantially cylindrical dial) and/or of the movement (for a cylindrical or substantially cylindrical movement ), when the dial and/or the movement are mounted in the case. The axis A3 can be the axis of revolution of the hands. The axis A3 can also correspond to the axis of revolution of the annular bezel 5. Preferably, the axis A1 is parallel to the dial of the watch. Preferably, the axis A3 is perpendicular to the dial of the watch.

L'élément de commande 1 comprend une tête 10 et une tige 11. La tige est fixée sur la tête, par exemple par vissage, notamment vissage de la tige 11 dans un taraudage prévu dans la tête.The control element 1 comprises a head 10 and a rod 11. The rod is fixed to the head, for example by screwing, in particular screwing the rod 11 into a thread provided in the head.

Par ailleurs, un guidage creux est réalisé dans la boîte, notamment dans la carrure, pour recevoir l'élément de commande 1. Ce guidage est par exemple réalisé par un tube 12, notamment un tube rapporté sur la carrure. Ce tube permet de recevoir la tige 11 et de guider ce dernier en coulissement relativement à la carrure.Furthermore, a hollow guide is produced in the case, in particular in the middle part, to receive the control element 1. This guide is for example produced by a tube 12, in particular a tube attached to the middle part. This tube makes it possible to receive the rod 11 and to guide the latter in sliding relative to the middle part.

Des garnitures d'étanchéité non représentées sur les figures peuvent être disposées à l'interface de l'axe et du tube de façon à garantir une étanchéité adéquate de la boîte de montre.Gaskets not shown in the figures can be arranged at the interface of the axis and the tube so as to guarantee adequate sealing of the watch case.

Le tube 12 peut, en outre, comporter un premier élément 12a de maintien en position angulaire de la tête 10 autour de l'axe A1. Ce premier élément de maintien coopère avantageusement avec un deuxième élément de maintien 10a prévu sur la tête 10, en particulier au niveau d'une jupe 101 de la tête 10.The tube 12 may further comprise a first element 12a for maintaining the angular position of the head 10 around the axis A1. This first holding element advantageously cooperates with a second holding element 10a provided on the head 10, in particular at the level of a skirt 101 of the head 10.

Par exemple, le premier élément de maintien peut comprendre des cannelures 12a externes et le deuxième élément de maintien peut comprendre des cannelures 10a internes. Ces cannelures sont formées autour de l'axe A1.For example, the first holding element may comprise external splines 12a and the second holding element may comprise internal splines 10a. These splines are formed around the axis A1.

Ainsi, l'élément de commande est monté en liaison glissière d'axe A1 dans le tube et, par conséquent, en liaison glissière d'axe A1 relativement à la carrure ou au reste de la boîte de montre.Thus, the control element is mounted in sliding connection with axis A1 in the tube and, consequently, in sliding connection with axis A1 relative to the middle part or to the rest of the watch case.

Le tube 12 peut par exemple être rapporté à la carrure 6 par chassage, soudage, brasage, vissage ou collage. Le tube peut être indexé à la carrure 6 par des moyens d'assemblage conventionnels.The tube 12 can for example be attached to the caseband 6 by driving in, welding, brazing, screwing or gluing. The tube can be indexed to the caseband 6 by conventional assembly means.

L'élément de commande diffère toutefois des éléments de commande de type poussoir conventionnels en ce que la jupe 101 de la tête 10 du poussoir 1 présente une échancrure 102 dont la fonction est détaillée plus bas. Autrement dit, la tête 10 de l'élément de commande est asymétrique avec une portion 10b qui fait saillie du corps de la tête 10 du poussoir comme représenté sur la figure 5.The control element, however, differs from conventional push-type control elements in that the skirt 101 of the head 10 of the push-button 1 has a notch 102 whose function is detailed below. In other words, the head 10 of the control element is asymmetrical with a portion 10b which protrudes from the body of the head 10 of the pusher as represented on the figure 5 .

De préférence, l'élément manipulable est monté mobile en rotation autour de l'axe A3 par rapport au reste de la boîte de montre, en particulier relativement à la carrure 6.Preferably, the manipulable element is mounted so as to be able to rotate around the axis A3 with respect to the rest of the watch case, in particular with respect to the middle part 6.

L'élément manipulable comprend une première bague 3. Cette première bague 3 est mobile en rotation autour de la lunette 5 et relativement à la carrure 6. De préférence, cette première bague a une section en L présentant une première aile 31 s'étendant radialement (c'est-à-dire perpendiculairement à l'axe A3) sous la lunette et une deuxième aile 32 s'étendant axialement (c'est-à-dire parallèlement à l'axe A3) sur le pourtour de la lunette. Ces deux ailes assurent ainsi deux fonctions principales.The manipulable element comprises a first ring 3. This first ring 3 is rotatable around the bezel 5 and relative to the middle part 6. Preferably, this first ring has an L-shaped section presenting a first wing 31 extending radially (that is to say perpendicular to the axis A3) under the bezel and a second wing 32 extending axially (that is to say parallel to the axis A3) on the rim of the lens. These two wings thus perform two main functions.

L'élément manipulable assure une fonction de préhension par le porteur. De préférence, la deuxième aile 32 assure cette fonction. En effet, c'est cette partie 32 de la première bague 3 que le porteur peut saisir entre ses doigts et sur laquelle il peut exercer une action mécanique de manière à faire tourner la première bague autour de la lunette. Pour faciliter la préhension et l'entraînement de la première bague par le porteur la deuxième aile peut être munie sur son pourtour de différents éléments de préhension 3c comme des encoches.The manipulable element performs a gripping function by the wearer. Preferably, the second wing 32 performs this function. Indeed, it is this part 32 of the first ring 3 that the wearer can grasp between his fingers and on which he can exert a mechanical action so as to cause the first ring to rotate around the bezel. To facilitate the gripping and driving of the first ring by the wearer, the second wing can be provided on its periphery with various gripping elements 3c such as notches.

L'élément manipulable assure une fonction de transmission du mouvement. De préférence, la première aile 31 assure principalement cette fonction. Pour ce faire, la première aile comprend un premier élément 3a de liaison cinématique. Ce premier élément 3a de liaison cinématique est, par exemple, une première denture 3a. Ce premier élément de liaison cinématique est par exemple disposé sous la première aile 31 au-dessus de laquelle est disposée la lunette.The manipulable element performs a motion transmission function. Preferably, the first wing 31 mainly performs this function. To do this, the first wing comprises a first element 3a of kinematic connection. This first kinematic link element 3a is, for example, a first toothing 3a. This first kinematic connecting element is for example arranged under the first wing 31 above which the bezel is arranged.

Les ébats, axial et radial relativement à l'axe A3, de l'élément manipulable 3 peuvent être limités par la lunette 5.The movement, axial and radial relative to the axis A3, of the manipulable element 3 can be limited by the bezel 5.

L'élément manipulable 3 est mobile entre une première position de verrouillage de l'au moins un élément de commande, c'est-à-dire une position dans laquelle on ne peut pas actionner un élément de commande ou on ne peut pas actionner suffisamment un élément de commande pour qu'il agisse sur le mouvement horloger, et une deuxième position de déverrouillage de l'au moins un élément de commande, c'est-à-dire une position dans laquelle il est possible d'actionner un élément de commande de sorte qu'il agisse sur le mouvement horloger. La première position est représentée sur la figure 6 et la deuxième position est représentée sur la figure 7. Les première et deuxième positions sont ainsi deux positions angulaires de l'élément manipulable 3 qui sont distinctes autour l'axe A3.The manipulable element 3 is movable between a first locking position of the at least one control element, that is to say a position in which one cannot actuate a control element or one cannot actuate sufficiently a control element so that it acts on the watch movement, and a second unlocking position of the at least one control element, that is to say a position in which it is possible to actuate a control so that it acts on the watch movement. The first one position is represented on the figure 6 and the second position is shown on the figure 7 . The first and second positions are thus two angular positions of the manipulable element 3 which are distinct around the axis A3.

Pour ce faire, l'élément manipulable 3 peut, par exemple, être indexé en position, dans ces deux positions relativement aux autres pièces fixes de la boîte de montre, notamment relativement à la carrure 6. Grâce à une telle indexation, les deux positions sont stables et peuvent être ressenties par le porteur. Ainsi, l'élément manipulable comprend de préférence un premier élément d'indexation 33. Ce premier élément coopère avec un deuxième élément d'indexation 34 pour réaliser l'indexation. Ce deuxième élément d'indexation est par exemple réalisé sur ou dans une autre pièce fixe de la boîte de montre, notamment sur ou dans la carrure 6.To do this, the manipulable element 3 can, for example, be indexed in position, in these two positions relative to the other fixed parts of the watch case, in particular relative to the middle part 6. Thanks to such indexing, the two positions are stable and can be felt by the wearer. Thus, the manipulable element preferably comprises a first indexing element 33. This first element cooperates with a second indexing element 34 to perform the indexing. This second indexing element is for example made on or in another fixed part of the watchcase, in particular on or in the middle part 6.

Par exemple, le dispositif d'indexation peut comprendre des premiers éléments d'indexation de type creusures 33, notamment des creusures réalisées sous l'élément manipulable, en particulier sous la première aile 31 de la première bague 3. Par exemple, le dispositif d'indexation comprend des deuxièmes éléments d'indexation de type cliquets à bille 34, comprenant des billes 4 logées dans des trous 42 et rappelées par des ressorts 41 contre l'élément manipulable. Ces deuxièmes éléments d'indexation sont par exemple prévus sur la carrure 6. Ils sont par exemple disposés sur le pourtour ou la circonférence de la carrure 6, soit sur un siège annulaire 60 de la carrure 6.For example, the indexing device can comprise first indexing elements of the hollow type 33, in particular hollows made under the manipulable element, in particular under the first wing 31 of the first ring 3. For example, the indexing device indexing comprises second indexing elements of the ball pawl type 34, comprising balls 4 housed in holes 42 and biased by springs 41 against the manipulable element. These second indexing elements are for example provided on the middle part 6. They are for example arranged on the periphery or the circumference of the middle part 6, or on an annular seat 60 of the middle part 6.

La première denture 3a peut être partielle sur l'élément manipulable. L'élément manipulable peut présenter autant de secteurs dentés 3a que d'éléments de verrouillage 2 à commander ou à positionner. La denture ou les dentures 3a peuvent être des dentures frontales.The first toothing 3a can be partial on the manipulable element. The manipulable element can have as many toothed sectors 3a as there are locking elements 2 to be controlled or positioned. The toothing or the toothings 3a can be frontal toothings.

L'élément manipulable 3 peut comporter une ou plusieurs butées 3b prévues pour coopérer par obstacle avec une autre ou plusieurs autres butées 6b prévues sur la carrure 6 comme représenté sur la figure 8. Ces butées permettent de limiter la rotation de l'élément manipulable autour de l'axe A3.The manipulable element 3 can comprise one or more stops 3b provided to cooperate by obstacle with another or several other stops 6b provided on the middle part 6 as represented on the figure 8 . These stops make it possible to limit the rotation of the manipulable element around the axis A3.

L'élément de verrouillage 2 comprend de préférence au moins un moyen de verrouillage d'un poussoir 1 et/ou d'une couronne. Dans le mode de réalisation décrit, l'élément de verrouillage 2 comprend des moyens de verrouillage de deux poussoirs 1.The locking element 2 preferably comprises at least one means for locking a pusher 1 and/or a crown. In the embodiment described, the locking element 2 comprises means for locking two pushers 1.

De préférence, les deux moyens de verrouillage ont des structures identiques ou similaires. Ainsi, un seul moyen de verrouillage 2 est décrit en détail ci-après.Preferably, the two locking means have identical or similar structures. Thus, a single locking means 2 is described in detail below.

L'élément de verrouillage 2 est monté mobile en rotation, notamment monté mobile en rotation autour de l'axe A1 de l'élément de commande, relativement au reste de la boîte de montre, en particulier relativement à la carrure. L'élément de verrouillage est bloqué en translation sur l'axe A1 de l'élément de commande, relativement au reste de la boîte de montre, en particulier relativement à la carrure, notamment par l'élément de commande 1. De préférence, l'élément de verrouillage a globalement la forme d'une deuxième bague 2. Cette deuxième bague est avantageusement disposée autour de l'élément de commande 1.The locking element 2 is rotatably mounted, in particular rotatably mounted around the axis A1 of the control element, relative to the rest of the watch case, in particular relative to the caseband. The locking element is blocked in translation on the axis A1 of the control element, relative to the rest of the watch case, in particular relative to the middle part, in particular by the control element 1. Preferably, the locking element has the overall shape of a second ring 2. This second ring is advantageously arranged around the control element 1.

L'élément de verrouillage comprend une première butée 2b empêchant ou limitant le déplacement de l'au moins un élément de commande. Cette première butée 2b est destinée à coopérer avec une deuxième butée 10b prévue sur l'élément de commande 1. Par exemple, la deuxième butée est une extrémité 10b de la jupe 101 du poussoir 1.The locking element comprises a first stop 2b preventing or limiting the movement of the at least one control element. This first stop 2b is intended to cooperate with a second stop 10b provided on the control element 1. For example, the second stop is an end 10b of the skirt 101 of the pusher 1.

La première butée 2b est par exemple un épaulement intérieur ou collerette intérieure prévu dans un alésage de la deuxième bague 2 et s'étendant préférentiellement sur moins de 180° autour de l'axe A1 comme représenté sur la figure 3.The first stop 2b is for example an internal shoulder or internal collar provided in a bore of the second ring 2 and preferably extending over less than 180° around the axis A1 as represented on the picture 3 .

De même, la deuxième butée 10b s'étend préférentiellement sur moins de 180° autour de l'axe A1.Similarly, the second stop 10b preferably extends over less than 180° around the axis A1.

Ainsi, dans une première position relative de l'élément de verrouillage 2 et de l'élément de commande 1 autour de l'axe A1 représentée sur la figure 6, les première et deuxième butées coopèrent et confinent ou bloquent l'élément de commande dans une position. En effet, les première et deuxième butées sont en face l'une de l'autre et la translation de l'élément de commande selon l'axe A1 est empêchée ou limitée, notamment en regard des tolérances de fabrication et d'assemblage des composants. Ainsi, le porteur ne peut pas agir sur le mouvement d'horlogerie via l'élément de commande.Thus, in a first relative position of the locking element 2 and the control element 1 around the axis A1 represented on the figure 6 , the first and second stops cooperate and confine or block the control element in one position. Indeed, the first and second stops are opposite each other and the translation of the control element along the axis A1 is prevented or limited, in particular with regard to the manufacturing and assembly tolerances of the components. . Thus, the wearer cannot act on the clock movement via the control element.

Dans une deuxième position relative de l'élément de verrouillage 2 et de l'élément de commande 1 autour de l'axe A1 représentée sur la figure 7, les première et deuxième butées ne peuvent pas coopérer. En effet, les première et deuxième butées ne sont plus en vis-à-vis et la translation de l'élément de commande selon l'axe A1 n'est plus limitée par les butées. Ainsi, le porteur peut agir sur le mouvement d'horlogerie via l'élément de commande.In a second relative position of the locking element 2 and the control element 1 around the axis A1 represented on the figure 7 , the first and second stops cannot cooperate. Indeed, the first and second stops are no longer facing each other and the translation of the control element along the axis A1 is no longer limited by the stops. Thus, the wearer can act on the clock movement via the control element.

Le système de verrouillage comprend de préférence un élément d'affichage 21 de l'état de verrouillage de l'au moins un élément de commande. Avantageusement, l'élément d'affichage 21 est formé sur l'élément de verrouillage. Par exemple, l'élément de verrouillage, en particulier la deuxième bague 2 peut comporter une ou des indication(s) ou marque(s) correspondant à l'état de verrouillage et/ou de déverrouillage de l'élément de commande 1.The locking system preferably comprises a display element 21 of the locking state of the at least one control element. Advantageously, the display element 21 is formed on the locking element. For example, the locking element, in In particular, the second ring 2 may include one or more indications or mark(s) corresponding to the locking and/or unlocking state of the control element 1.

Pour ce faire, l'élément de verrouillage 2 peut notamment comporter un organe indicateur 21 prévu pour indiquer l'état de l'élément de commande. Cet organe indicateur 21 peut notamment être pourvu d'indications ou de marques renseignant le porteur de la montre sur l'état d'activation de l'élément de commande. A titre d'exemple, les figures 1 et 3 illustrent un organe indicateur 21 pourvu de gravures « A » et « D », « A » correspondant à l'état activé ou déverrouillé de l'élément de commande et « D » correspondant à l'état désactivé ou verrouillé de l'élément de commande. Alternativement, l'organe indicateur peut, par exemple, être pourvu d'un code couleur correspondant à chacun des états du bouton poussoir.To do this, the locking element 2 may in particular comprise an indicator member 21 provided to indicate the state of the control element. This indicator member 21 may in particular be provided with indications or marks informing the wearer of the watch of the activation state of the control element. For example, the figure 1 and 3 illustrate an indicator member 21 provided with engravings "A" and "D", "A" corresponding to the activated or unlocked state of the control element and "D" corresponding to the deactivated or locked state of the control element. ordered. Alternatively, the indicator member can, for example, be provided with a color code corresponding to each of the states of the push button.

L'élément de verrouillage a globalement la forme d'une deuxième bague 2, qui peut comprendre un corps de bague 20 sur lequel est rapporté l'organe indicateur 21. L'organe indicateur 21 peut par exemple être solidarisé au corps 20 par chassage, par soudage, ou par brasage.The locking element has the overall shape of a second ring 2, which can comprise a ring body 20 on which the indicator member 21 is attached. The indicator member 21 can for example be secured to the body 20 by driving in, by welding or brazing.

L'élément de verrouillage comprend de préférence une denture 2a. La denture est par exemple une denture extérieure 2a prévue autour de la deuxième bague 2, notamment prévue autour du corps 20 de deuxième bague.The locking element preferably comprises a toothing 2a. The toothing is for example an external toothing 2a provided around the second ring 2, in particular provided around the body 20 of the second ring.

L'élément de verrouillage 2 peut être pivoté sur le tube 12 et/ou sur la tête 10. Avantageusement, l'élément de verrouillage 2 est délimité axialement selon l'axe A1 par un flanc de la carrure 6 et par la tête 10 de l'élément de commande.The locking element 2 can be pivoted on the tube 12 and/or on the head 10. Advantageously, the locking element 2 is delimited axially along the axis A1 by a side of the middle part 6 and by the head 10 of the control element.

La liaison cinématique comprend, par exemple, la première denture 3a réalisée sur l'élément manipulable et la deuxième denture 2a réalisée sur l'élément de verrouillage. De préférence, les première et deuxième dentures coopèrent directement par engrènement l'une avec l'autre. Alternativement, les première et deuxième dentures peuvent coopérer l'une avec l'autre via un élément intermédiaire comme un renvoi.The kinematic link comprises, for example, the first toothing 3a made on the manipulable element and the second toothing 2a made on the locking element. Preferably, the first and second toothings cooperate directly by meshing with each other. Alternatively, the first and second gears can cooperate with each other via an intermediate element such as a transmission.

Dans le mode de réalisation représenté, les dentures 2a et 3a coopèrent au niveau du siège annulaire 60 de la carrure 6. Pour ce faire, le siège annulaire 60 est muni d'au moins une découpe 60a de façon à ce que le contact s'opère entre les dentures 2a et 3a. Cette coopération entre les dentures 2a et 3a s'effectue en aval des garnitures d'étanchéité disposées entre les éléments constituant la boîte de la pièce d'horlogerie, notamment entre les organes 1 et 6, 5 et 6, et 61 et 6. Ainsi, cette liaison cinématique est sans conséquence sur l'étanchéité de la boîte de montre.In the embodiment shown, the teeth 2a and 3a cooperate at the level of the annular seat 60 of the middle part 6. To do this, the annular seat 60 is provided with at least one cutout 60a so that the contact is operates between the teeth 2a and 3a. This cooperation between the toothings 2a and 3a takes place downstream of the seals arranged between the elements constituting the case of the timepiece, in particular between the members 1 and 6, 5 and 6, and 61 and 6. Thus , this kinematic connection has no effect on the tightness of the watch case.

De préférence, la liaison cinématique est desmodromique.Preferably, the kinematic link is desmodromic.

La liaison cinématique peut être de toute nature pourvu que :

  • un passage de la première position à la deuxième position de l'élément manipulable provoque, via cette liaison cinématique, un passage de la première position à la deuxième position de l'élément de verrouillage ; et
  • un passage de la deuxième position à la première position de l'élément manipulable provoque, via cette liaison cinématique, un passage de la deuxième position à la première position de l'élément de verrouillage.
The kinematic connection can be of any kind provided that:
  • a passage from the first position to the second position of the manipulable element causes, via this kinematic connection, a passage from the first position to the second position of the locking element; and
  • a passage from the second position to the first position of the manipulable element causes, via this kinematic connection, a passage from the second position to the first position of the locking element.

La figure 6 représente une vue de coupe en configuration verrouillée de l'élément de commande 1. Dans cette configuration, l'élément manipulable 3 est disposé, préférentiellement maintenu, dans une première position angulaire déterminée de façon à ce qu'elle positionne, préférentiellement maintienne, l'élément de verrouillage dans une position angulaire définie de telle sorte qu'il interdit la translation de l'élément de commande. Pour ce faire, l'élément de verrouillage 2 est pourvu de la collerette 2b prévue pour coopérer par obstacle avec une portion 10b de la tête 10 de l'élément de commande 1. Ainsi, dans cette configuration, l'élément de verrouillage 2 est orienté de sorte à ce que la collerette 2b s'oppose à la translation de l'élément de commande en constituant une butée de la tête 10, notamment d'une portion 10b de tête.The figure 6 represents a sectional view in locked configuration of the control element 1. In this configuration, the element manipulable 3 is arranged, preferably maintained, in a first determined angular position so that it positions, preferably maintains, the locking element in a defined angular position such that it prevents the translation of the locking element ordered. To do this, the locking element 2 is provided with the flange 2b provided to cooperate by obstacle with a portion 10b of the head 10 of the control element 1. Thus, in this configuration, the locking element 2 is oriented so that the flange 2b opposes the translation of the control element by constituting an abutment of the head 10, in particular of a portion 10b of the head.

La figure 7 représente une vue de coupe en configuration déverrouillée de l'élément de commande 1. Dans cette configuration, l'élément manipulable 3 est positionné, préférentiellement maintenu, dans une deuxième position angulaire déterminée de façon à ce qu'elle positionne, préférentiellement maintienne, l'élément de verrouillage 2 dans une position angulaire définie de telle sorte qu'il autorise la translation de l'élément de commande. Pour ce faire, l'élément de verrouillage 2 est positionné de sorte que la collerette 2b est positionnée hors de portée de la portion 10b de la tête 10. Ainsi, l'élément de commande 1 peut être translaté sur une portion suffisamment étendue pour activer une fonctionnalité du mouvement horloger.The figure 7 represents a sectional view in the unlocked configuration of the control element 1. In this configuration, the manipulable element 3 is positioned, preferably maintained, in a second angular position determined so that it positions, preferably maintains, the locking element 2 in an angular position defined so that it allows the translation of the control element. To do this, the locking element 2 is positioned so that the collar 2b is positioned out of reach of the portion 10b of the head 10. Thus, the control element 1 can be translated over a sufficiently large portion to activate a feature of the watch movement.

Le passage de la configuration verrouillée de la figure 6 à la configuration déverrouillée de la figure 7 s'effectue par une rotation de l'élément de verrouillage 2 autour de l'axe A1, notamment par une rotation de l'élément de verrouillage 2 sur un angle α2 de 180°. La rotation de l'élément de verrouillage 2 s'effectue sous l'effet de la rotation de l'élément manipulable 3, lui-même entraîné en rotation par le porteur de la montre, notamment entraîné en rotation sur un angle α3 inférieur ou égal à 180°, voire inférieur ou égal à 45°, voire inférieur ou égal à 30°, autour de l'axe A3. Par exemple, l'élément manipulable 3 est prévu pour tourner d'un angle de 24° ou environ.Switching from the locked configuration of the figure 6 to the unlocked configuration of the figure 7 is effected by a rotation of the locking element 2 around the axis A1, in particular by a rotation of the locking element 2 over an angle α2 of 180°. The rotation of the locking element 2 takes place under the effect of the rotation of the manipulable element 3, itself driven in rotation by the wearer of the watch, in particular driven in rotation over an angle α3 less than or equal at 180°, or even less than or equal to 45°, or even less than or equal to 30°, around axis A3. For example, the manipulable element 3 is designed to rotate through an angle of 24° or approximately.

Bien entendu, l'élément manipulable 3 peut verrouiller et déverrouiller plusieurs éléments de commande 1, notamment deux éléments de commande 1 simultanément. Ainsi, avantageusement, l'élément manipulable 3 permet de verrouiller ou de déverrouiller, d'une seule et même opération, deux éléments de commande.Of course, the manipulable element 3 can lock and unlock several control elements 1, in particular two control elements 1 simultaneously. Thus, advantageously, the manipulable element 3 makes it possible to lock or unlock, in a single and same operation, two control elements.

Un deuxième mode de réalisation d'une pièce d'horlogerie est décrit ci-après en référence à la figure 9.A second embodiment of a timepiece is described below with reference to the figure 9 .

La pièce d'horlogerie 200* comprend une boîte de montre 150* munie d'un système de verrouillage 100* d'au moins un élément de commande 1*.The timepiece 200* comprises a watchcase 150* provided with a locking system 100* of at least one control element 1*.

Le système 100* de verrouillage d'au moins un élément de commande 1* de la pièce d'horlogerie 200, comprend :

Complémentairement ou alternativement, les axes A1* et A3* peuvent se trouver dans un même plan ou sensiblement dans un même plan, notamment un plan parallèle au plan du mouvement de la pièce d'horlogerie ou dans un plan parallèle au cadran de la pièce d'horlogerie.This second embodiment differs or differs mainly from the first embodiment in that the manipulable element 3* is rotatably mounted relative to an axis A3* parallel or substantially parallel to an axis A1* of the at least one element control. Complementarily or alternatively, the axes A1* and A3* may be in the same plane or substantially in the same plane, in particular a plane parallel to the plane of movement of the timepiece or in a plane parallel to the dial of the timepiece.

L'élément manipulable 3* peut être disposé concentriquement à une couronne 7* de remontoir qui est positionnée entre deux boutons poussoirs 1* autour desquels sont disposés des éléments de verrouillage 2*. L'élément manipulable est par exemple une première bague 3* et les éléments de verrouillage sont par exemple des deuxièmes bagues 2*. Ces bagues présentent avantageusement des dentures 2a* et 3a* engrenant les unes avec les autres. Ainsi, dans ce deuxième mode de réalisation, on peut verrouiller ou déverrouiller, par rotation de la bague 3*, d'une seule et même opération, les deux éléments de commande 1*.The manipulable element 3* can be arranged concentrically to a winding crown 7* which is positioned between two push-buttons 1* around which are arranged locking elements 2*. The manipulable element is for example a first 3* ring and the locking elements are for example second 2* rings. These rings advantageously have teeth 2a* and 3a* meshing with each other. Thus, in this second embodiment, it is possible to lock or unlock, by rotation of the ring 3*, in a single and same operation, the two control elements 1*.

Alternativement aux différents modes de réalisation et variantes décrits, l'élément manipulable et/ou l'élément de verrouillage peuvent être mobiles en translation relativement au reste de la boîte de montre, en particulier relativement à la carrure.Alternatively to the different embodiments and variants described, the manipulable element and/or the locking element can be movable in translation relative to the rest of the watch case, in particular relative to the middle part.

Alternativement aux différents modes de réalisation et variantes décrits, l'élément manipulable peut être une lunette rotative.Alternatively to the different embodiments and variants described, the manipulable element can be a rotating bezel.

Complémentairement aux différents modes de réalisation et variantes décrits, l'élément manipulable peut être positionné dans une troisième position, notamment une troisième position intermédiaire entre les première et deuxième positions, dans laquelle au moins un élément de commande est verrouillé et au moins un élément de commande est déverrouillé. La première position peut être une position dans laquelle tous les éléments de commande sont verrouillés et la deuxième peut être une position dans laquelle aucun élément de commande n'est verrouillé.In addition to the different embodiments and variants described, the manipulable element can be positioned in a third position, in particular a third intermediate position between the first and second positions, in which at least one control element is locked and at least one command is unlocked. The first position can be a position in which all the control elements are locked and the second can be a position in which no control element is locked.

Alternativement aux différents modes de réalisation et variantes décrits, l'élément d'affichage 21 peut être en liaison cinématique avec l'élément de verrouillage, notamment l'élément d'affichage peut être un organe distinct de l'élément de verrouillage et/ou de l'élément manipulable et entraîné mécaniquement par l'élément de verrouillage et/ou par l'élément manipulable.Alternatively to the various embodiments and variants described, the display element 21 may be in kinematic connection with the locking element, in particular the display element may be a separate member of the locking element and/or of the manipulable element and driven mechanically by the locking element and/or by the manipulable element.

Dans les différents modes de réalisation et variantes décrits, le système de verrouillage est externe à la chambre 63 constituée par la boîte de montre. Cette chambre est notamment délimitée par la carrure 6, le fond 61 de la carrure 6, la lunette 5, la glace 62, et l'élément de commande 1.

De telles garnitures d'étanchéités peuvent être mises en œuvre par un ou plusieurs joints d'étanchéité. A titre d'exemple, la figure 10 met en évidence les garnitures d'étanchéité pouvant être disposées à l'interface des éléments précités.In the different embodiments and variants described, the locking system is external to the chamber 63 constituted by the watch case. This chamber is in particular delimited by the caseband 6, the back 61 of the caseband 6, the bezel 5, the crystal 62, and the control element 1. Preferably, a first seal 610 is arranged between the back 61 and caseband 6, a second sealing gasket 510 is placed between caseband 6 and bezel 5, a second sealing gasket 510 is placed between caseband 6 and crystal 62, a third sealing gasket 110 is placed between the middle 6 and a control element 1, so that the chamber 63 constitutes a sealed chamber. Such seals can be implemented by one or more seals. For example, the figure 10 highlights the seals that can be placed at the interface of the aforementioned elements.

Dans les différents modes de réalisation et variantes décrits, les éléments de verrouillage 2 sont majoritairement inclus dans l'épaisseur de la carrure.
