Description

OBJET DE L'INVENTIONOBJECT OF THE INVENTION

La présente invention se rapporte à une pièce d'horlogerie munie d'un mécanisme permettant d'escamoter un organe d'actionnement, et, en particulier, un poussoir de chronographe, lorsqu'il n'est pas en fonction.The present invention relates to a timepiece provided with a mechanism for retracting an actuating member, and in particular a chronograph pusher, when it is not in use.

ARRIÈRE-PLAN TECHNOLOGIQUE ET ÉTAT DE LA TECHNIQUETECHNOLOGICAL BACKGROUND AND STATE OF THE ART

Pour éviter les déclenchements intempestifs des chronographes de montres ainsi que des dégâts aux organes de commande associés tels que les poussoirs, il est préférable de masquer ces derniers tant que l'utilisateur n'en fait pas usage. A cet effet, différents systèmes sont proposés. Il existe des caches solidaires de la lunette tournante comme décrit dans le document CH 567 300 où la lunette est munie d'une portée qui en fonction du placement angulaire de la lunette vient respectivement recouvrir ou pas les poussoirs. Ces systèmes ont pour désavantage d'être encombrants et peu esthétiques. Il existe également des systèmes avec poussoirs escamotables tels que décrits dans le document EP 1 582 945 où le déplacement du poussoir entre une position escamotée et une position déployée est lié au déplacement angulaire d'une paroi solidaire de la lunette. Dans cette invention, la paroi recouvre et comprime le poussoir vers l'intérieur du boîtier lorsqu'elle est en regard du poussoir et inversement le libère en position extérieure prête à l'usage lorsque la paroi n'est pas en vis-à-vis. Ce système présente comme désavantage qu'un frottement, d'autant plus marqué en présence de poussières, s'établit constamment entre la surface extérieure du poussoir et la paroi de la lunette lors du mouvement de rotation de la lunette. A la longue, des rainures inesthétiques vont se creuser sur une partie du poussoir qui est visible à l'oeil de l'utilisateur lorsque le poussoir est en position déployée.To avoid accidental tripping of watch chronographs as well as damage to associated control components such as push buttons, it is best to hide them as long as the user does not use them. For this purpose, different systems are proposed. There are integral covers of the rotating bezel as described in the document CH 567 300 where the bezel is provided with a scope that depending on the angular positioning of the bezel respectively covers or not the pushers. These systems have the disadvantage of being bulky and unattractive. There are also systems with retractable pushbuttons as described in the document EP 1 582 945 where the displacement of the pusher between a retracted position and an extended position is related to the angular displacement of a wall integral with the telescope. In this invention, the wall covers and compresses the pusher towards the inside of the casing when it is facing the pusher and conversely releases it into an external position ready for use when the wall is not facing each other. . This system has the disadvantage that a friction, all the more marked in the presence of dust, is established constantly between the outer surface of the pusher and the wall of the bezel during the rotational movement of the bezel. In the long run, unsightly grooves will widen on a portion of the pusher that is visible to the user's eye when the pusher is in the deployed position.

RÉSUMÉ DE L'INVENTIONSUMMARY OF THE INVENTION

La présente invention a pour but de pallier aux inconvénients de l'état de la technique en réalisant une pièce d'horlogerie munie d'un mécanisme d'escamotage ne nécessitant pas de mouvement relatif entre la surface extérieure visible du poussoir et la pièce coopérant avec ce dernier lors de l'escamotage.The present invention aims to overcome the drawbacks of the state of the art by producing a timepiece provided with a retraction mechanism that does not require relative movement between the visible outer surface of the pusher and the part cooperating with the latter during the retraction.

A cette fin, une pièce d'horlogerie selon la revendication 1 annexée est proposée et des formes d'exécution particulières sont reprises dans les revendications dépendantes.For this purpose, a timepiece according to the appended claim 1 is proposed and particular embodiments are included in the dependent claims.

DESCRIPTION DÉTAILLÉE DE L'INVENTIONDETAILED DESCRIPTION OF THE INVENTION

La présente invention se rapporte à une pièce d'horlogerie du type montre-bracelet munie d'un ou de plusieurs poussoirs destinés à actionner une fonction telle que, par exemple, une fonction de chronographe. Selon l'invention, la montre-bracelet est munie de moyens pour escamoter les poussoirs lorsqu'ils ne sont pas en fonction.The present invention relates to a timepiece of the wristwatch type provided with one or more pushers intended to actuate a function such as, for example, a chronograph function. According to the invention, the wristwatch is provided with means for retracting the pushers when they are not in use.

La montre-bracelet 1 visible entre autres aux figures 1 et 2 comporte une lunette tournante bidirectionnelle 2 montée à rotation sur une carrure 6 de manière classique. Dans l'exemple représenté, la lunette 2 comprend une portée cylindrique intérieure 2a ajustée sur une portée cylindrique extérieure 6a de la carrure pour assurer un guidage en rotation de la lunette sur la carrure 6 (voir figure 4). La retenue axiale de la lunette 2 sur la carrure est assurée par une bague 3 disposée dans un logement L formé partiellement dans la portée cylindrique intérieure 2a la lunette et dans la portée cylindrique extérieure 6a de la carrure lorsque la lunette est en place sur la carrure. Plus précisément, le logement L est formé par des gorges annulaires radiales ménagées respectivement dans la portée cylindrique intérieure la lunette et dans la portée cylindrique extérieure de la carrure en regard l'une de l'autre, la bague étant montée dans ce logement de façon à ce qu'elle s'étende en position montée à la fois dans la gorge de la lunette et dans la gorge de la carrure. La carrure 6 comprend à sa surface périphérique supérieure des graduations et, par exemple, des graduations fixes d'un tachymètre. L'organe d'actionnement de la fonction à déclencher comporte un capot 8 abritant un poussoir 12 représenté en détail à la figure 17. Le poussoir 12 comprend classiquement une tête d'actionnement 12a fixée à une extrémité d'une tige 15 guidée en translation et rappelée par un ressort 13 dans un tube 16 vissé de manière étanche dans la carrure 6. Comme montré, entre autres, aux figures 4 et 5, l'extrémité opposée de la tige 15 s'étendant à l'intérieur de la carrure est destinée à coopérer avec un organe de commande 4 de la fonction à actionner associé au poussoir 12.The wristwatch 1 visible among others to Figures 1 and 2 comprises a bidirectional rotating bezel 2 rotatably mounted on a middle part 6 in a conventional manner. In the example shown, the window 2 comprises an inner cylindrical surface 2a fitted on an outer cylindrical surface 6a of the middle part to ensure a rotation guide of the window on the middle part 6 (see figure 4 ). The axial retention of the bezel 2 on the middle part is provided by a ring 3 disposed in a housing L partially formed in the inner cylindrical bearing surface 2a the bezel and in the outer cylindrical bearing surface 6a of the middle part when the bezel is in place on the middle part . More specifically, the housing L is formed by radial annular grooves formed respectively in the inner cylindrical surface of the bezel and in the outer cylindrical surface of the middle part facing one another, the ring being mounted in this housing so as to it extends in mounted position both in the groove of the telescope and in the groove of the middle part. The caseband 6 comprises at its upper peripheral surface graduations and, for example, fixed graduations of a tachymeter. The actuating member of the function to be triggered comprises a cover 8 housing a pusher 12 shown in detail at figure 17 . The pusher 12 conventionally comprises an actuating head 12a attached to one end of a rod 15 guided in translation and biased by a spring 13 into a tube 16 screwed tightly into the middle part 6. As shown, inter alia, to the figures 4 and 5 , the opposite end of the rod 15 extending inside the middle part is intended to cooperate with a control member 4 of the function to be actuated associated with the pusher 12.

Selon l'invention, le capot 8 est monté mobile et peut adopter respectivement une position déployée extérieure à la carrure 6, une position escamotée intérieure à la carrure 6, et une position fonctionnelle également intérieure à la carrure mais présentant un débattement à l'intérieur de la carrure plus important que pour la position escamotée. Le capot 8 peut être monté pivotant comme représenté aux figures 1 à 16. Selon un autre mode de réalisation non représenté, le capot 8 pourrait être monté en translation sur la carrure.According to the invention, the cover 8 is movably mounted and can adopt respectively an extended position outside the middle 6, a retracted position inside the middle 6, and a functional position also interior to the middle part but having a greater clearance inside the middle part than for the retracted position. The cover 8 can be pivotally mounted as shown in FIGS. Figures 1 to 16 . According to another embodiment not shown, the cover 8 could be mounted in translation on the middle part.

Dans l'exemple illustré, le capot 8 est monté pivotant autour d'un axe 9 solidaire de la carrure 6. De préférence, le capot 8 s'étend dans un dégagement de la carrure. Une première position illustrée aux figures 1 à 5 est la position escamotée où le capot 8 est logé dans le dégagement et sa surface supérieure affleure au niveau de la surface extérieure de la carrure 6 pour des raisons esthétiques et pour éviter tout accrochage. Une seconde position est la position déployée où le capot 8 libre de se déplacer pivote vers l'extérieur de la carrure 6 (figures 6 à 10). De cette position découle la position fonctionnelle où, suite à l'actionnement par l'utilisateur, le capot 8 pivote vers l'intérieur de la carrure 6 pour déclencher la fonction associée (figures 11 à 14).In the example shown, the cover 8 is pivotally mounted about an axis 9 secured to the middle part 6. Preferably, the cover 8 extends in a clearance of the middle part. A first position illustrated Figures 1 to 5 is the retracted position where the cover 8 is housed in the clearance and its upper surface is flush with the outer surface of the middle part 6 for aesthetic reasons and to avoid any attachment. A second position is the deployed position where the cover 8 free to move pivots outwardly of the middle part 6 ( Figures 6 to 10 ). From this position derives the functional position where, following the actuation by the user, the cover 8 pivots inwards of the middle part 6 to trigger the associated function ( Figures 11 to 14 ).

Selon l'invention, le déplacement du capot entre la position escamotée et la position déployée est couplé au déplacement angulaire de la lunette 2. Le capot 8 et la lunette 2 ont un profil particulier qui assure la coopération entre ces deux pièces comme il sera décrit ci-dessous.According to the invention, the movement of the cover between the retracted position and the deployed position is coupled to the angular displacement of the bezel 2. The cover 8 and the bezel 2 have a particular profile which ensures the cooperation between these two parts as will be described below.

Le capot 8 visible en détail aux figures 15 et 16 est surmonté par la surface d'appui 10 actionnable par le doigt d'un utilisateur. Il comporte sur une face latérale un épaulement 11 qui est distinct de la surface d'appui 10 et forme une surface de guidage présentant un profil, de préférence en arc de cercle, coopérant avec la lunette 2 lors de rotation de celle-ci. A cet effet, la lunette 2 comporte sur une partie de son périmètre une partie en jupe définissant des rebords 5 faisant saillie vers le fond de la montre-bracelet et se déplaçant sur la surface de guidage des différents capots (figures 3 à 5). Ces rebords 5 en arc de cercle disposés à intervalle sur le périmètre de la lunette s'étendent autour de la surface latérale externe de la carrure 6 au-dessus des cornes 7 de la carrure.The cover 8 visible in detail at Figures 15 and 16 is surmounted by the bearing surface 10 actuated by the finger of a user. It comprises on a lateral face a shoulder 11 which is distinct from the bearing surface 10 and forms a guide surface having a profile, preferably in a circular arc, cooperating with the bezel 2 during rotation thereof. For this purpose, the bezel 2 has on part of its perimeter a skirt portion defining flanges 5 protruding towards the bottom of the wristwatch and moving on the guiding surface of the various covers ( Figures 3 to 5 ). These flanges 5 arcuate disposed at intervals on the perimeter of the bezel extend around the outer lateral surface of the middle part 6 above the horns 7 of the middle part.

Les rebords 5 sont agencés sur le périmètre de la lunette de manière à ce qu'en position neutre de la lunette, ils soient en vis-vis des capots 8 afin de coopérer avec les épaulements 11 comme illustré à la figure 3. Dans cette configuration, chaque capot 8 est maintenu en position escamotée par un rebord 5 prenant appui sur son épaulement 11. Lors de la rotation de la lunette d'un angle donné qui est fonction de la longueur des rebords et de l'intervalle entre les rebords, ces derniers ne sont plus en contact avec le capot 8 comme montré à la figure 8. Dès lors, le capot 8 sous l'effet du ressort 13 du poussoir 12 pivote vers l'extérieur de la carrure 6 (figures 8 à 10). Le déploiement maximum du capot 8 vers l'extérieur est limité par sa paroi extérieure latérale du côté de son axe de pivotement 9 qui vient en butée contre une surface latérale du dégagement de la carrure 6 dans lequel est monté le capot 8 comme montré à la figure 8. Le capot est ainsi en position déployée et peut être actionné par l'utilisateur. En fonction, le capot 8 pivote vers l'intérieur de la carrure 6 avec un débattement maximum qui est limité par le déplacement du poussoir 12 butant sur le tube 16 fixe entourant la tige 15 du poussoir (figures 11 à 14).The flanges 5 are arranged on the perimeter of the telescope so that in the neutral position of the telescope, they are facing caps 8 in order to cooperate with the shoulders 11 as illustrated in the figure 3 . In this configuration, each cover 8 is held in the retracted position by a flange 5 resting on its shoulder 11. When rotating the bezel by a given angle which is a function of the length of the flanges and the interval between them. edges, they are no longer in contact with the hood 8 as shown in figure 8 . Therefore, the cover 8 under the effect of the spring 13 of the pusher 12 pivots outwardly of the middle part 6 ( Figures 8 to 10 ). The maximum deployment of the cover 8 to the outside is limited by its lateral outer wall on the side of its pivot axis 9 which abuts against a lateral surface of the clearance of the middle part 6 in which the cover 8 is mounted as shown in FIG. figure 8 . The cover is thus in the deployed position and can be actuated by the user. In function, the cover 8 pivots towards the inside of the middle part 6 with a maximum displacement which is limited by the displacement of the pusher 12 abutting on the fixed tube 16 surrounding the rod 15 of the pusher ( Figures 11 to 14 ).

Chaque épaulement 11 offre une surface de guidage dessinée pour faciliter l'engagement du rebord sur l'épaulement lorsque le capot 8 bascule de la position déployée de la figure 8 à la position escamotée de la figure 3. Pour faciliter cet engagement, l'épaulement 11 doit se présenter de biais par rapport à la lunette 2 lorsque le capot 8 est en position déployée. Cette configuration de biais peut être induite par le pivotement comme illustré à la figure 8 ou être obtenue en ménageant un épaulement 11 avec l'inclinaison requise dans le capot, dans le cas d'un capot monté mobile en translation.Each shoulder 11 has a guide surface designed to facilitate the engagement of the flange on the shoulder when the cover 8 tilts from the extended position of the figure 8 in the retracted position of the figure 3 . To facilitate this engagement, the shoulder 11 must be angled relative to the bezel 2 when the cover 8 is in the deployed position. This bias configuration can be induced by pivoting as shown in FIG. figure 8 or be obtained by providing a shoulder 11 with the required inclination in the hood, in the case of a cover mounted to move in translation.

De préférence, des moyens de verrouillage sont prévus pour que l'utilisateur ne puisse pas actionner l'organe de commande par pression sur la surface d'appui lorsque le capot 8 est en position escamotée. Les moyens de verrouillage non représentés peuvent comporter une butée solidaire de la lunette ou de la carrure limitant le débattement du capot vers l'intérieur de la carrure. En outre, pour éviter que la lunette ne se déplace librement en dehors de positions angulaires déterminées correspondant aux positions escamotée et déployée du capot, la montre est munie de moyens de blocage de type connu comme des billes à ressort. La montre comporte en outre des moyens pour limiter le déplacement angulaire de la lunette afin d'éviter que lorsque le capot est déployé, une rotation de la lunette dans le mauvais sens ne détériore les capots et les rebords. Par exemple, les moyens peuvent être des butées montées sur la carrure coopérant avec la lunette.Preferably, locking means are provided so that the user can not actuate the control member by pressing on the support surface when the cover 8 is in the retracted position. The not shown locking means may comprise an abutment integral with the bezel or the middle part limiting the movement of the cover towards the inside of the middle part. In addition, to prevent the telescope from moving freely outside defined angular positions corresponding to the retracted and deployed positions of the cover, the watch is provided with locking means of known type as spring balls. The watch further comprises means for limiting the angular displacement of the telescope to prevent that when the hood is deployed, a rotation of the telescope in the wrong direction does not damage the covers and the edges. For example, the means may be stops mounted on the middle part cooperating with the bezel.

A titre illustratif, la présente invention a été décrite pour une montre-bracelet comportant deux poussoirs avec des axes respectifs disposés à +28° et -28° par rapport à la position de 3 heures, un déplacement angulaire de 30° de la lunette entraînant un changement de position des poussoirs. Il va de soi que d'autres configurations sont couvertes par la présente invention. De même, dans l'exemple illustré, les capots pivotent simultanément vers l'extérieur de la carrure dans le sens antihoraire lors de la rotation antihoraire de la lunette. Inversement, les axes de pivotement peuvent être agencés pour que les capots se déploient dans le sens horaire lors de la rotation horaire de la lunette.By way of illustration, the present invention has been described for a wristwatch comprising two pushers with respective axes arranged at + 28 ° and -28 ° with respect to the 3 o'clock position, an angular displacement of 30 ° of the driving bezel. a change of position of the pushers. It goes without saying that other configurations are covered by the present invention. Similarly, in the example illustrated, the covers pivot simultaneously outwardly of the middle part in the counterclockwise direction during the counterclockwise rotation of the bezel. Conversely, the pivot axes can be arranged so that the covers are deployed in the clockwise direction during the clockwise rotation of the telescope.

Pour finir, on précisera, en ce qui concerne le capot 8 du poussoir, que l'épaulement peut être ménagé dans le capot ou formé en rapportant une pièce sur un capot de poussoir conventionnel comme montré à la figure 16. Aussi, le capot et le poussoir peuvent former deux pièces distinctes comme dans l'exemple illustré ou former un seul élément et ce, en particulier, pour le mode de réalisation avec capot monté mobile en translation où le poussoir et le capot peuvent se déplacer conjointement en translation.Finally, it will be specified, as regards the cover 8 of the pusher, that the shoulder can be formed in the cover or formed by bringing a part to a conventional pusher cover as shown in FIG. figure 16 . Also, the cover and the pusher can form two separate parts as in the illustrated example or form a single element and this, in particular, for the embodiment with the cover mounted in translation where the pusher and the cover can move together in translation.

AVANTAGES DE L'INVENTIONADVANTAGES OF THE INVENTION

Grâce au mécanisme d'escamotage selon l'invention, la surface d'appui du capot 8 n'est pas soumise à des frottements lors du déplacement angulaire de la lunette 2. Seul l'épaulement qui n'est pas visible depuis l'extérieur de la carrure lorsque le poussoir est escamoté coopère avec la lunette et est donc susceptible de se griffer. Il s'ensuit que le capot du poussoir ne subit pas d'usure excessive liée à l'utilisation du poussoir. Ainsi, seule la pièce formant l'épaulement peut être réalisée dans un matériau résistant à l'usure, ce dernier pouvant, par exemple, être une céramique ou tout autre matériau ayant une résistance à l'usure analogue.Thanks to the retraction mechanism according to the invention, the bearing surface of the cover 8 is not subjected to friction during the angular displacement of the bezel 2. Only the shoulder which is not visible from the outside the middle when the pusher is retracted cooperates with the bezel and is likely to scratch. It follows that the pusher cover does not undergo excessive wear related to the use of the pusher. Thus, only the piece forming the shoulder may be made of a wear resistant material, the latter may, for example, be a ceramic or any other material having a similar wear resistance.

Dans l'exemple décrit ci-dessus, la lunette est actionnée en rotation directement manuellement par l'utilisateur, mais il va de soi que selon une variante non représentée, on peut prévoir que la lunette soit mise en rotation par un mécanisme du type poussoir et leviers ou par un mécanisme à molette relié cinématiquement à la lunette via une roue dentée ou analogue.In the example described above, the bezel is actuated in rotation directly manually by the user, but it goes without saying that according to a variant not shown, it can be provided that the bezel is rotated by a mechanism of the push and levers or by a wheel mechanism kinematically connected to the bezel via a gear wheel or the like.
