Description

Domaine de l'inventionField of the invention

L'invention concerne un ensemble constitué d'une montre et d'au moins un mécanisme additionnel de remontage automatique, ladite montre comportant une boîte renfermant un mouvement et au moins un accumulateur d'énergie rechargé en énergie par au moins un mécanisme de remontoir, ladite montre étant agencée pour recevoir, fixé sur ladite boîte ou sur un bracelet ou sur un composant d'habillage de ladite montre disposé à proximité immédiate de ladite boîte, au moins un dit mécanisme additionnel de remontage automatique comportant une masse oscillante et prévu pour être porté en même temps que ladite montre par un utilisateur et comportant au moins un mobile émetteur agencé pour être entraîné par ladite masse oscillante et agencé pour coopérer sans contact avec au moins un mobile récepteur que comporte un dit mécanisme de remontoir.The invention relates to an assembly consisting of a watch and at least one additional mechanism for automatic winding, said watch comprising a box containing a movement and at least one energy accumulator recharged with energy by at least one winding mechanism, said watch being arranged to receive, fixed on said box or on a bracelet or on a covering component of said watch disposed in the immediate vicinity of said box, at least one said additional automatic winding mechanism comprising an oscillating mass and intended to be worn at the same time as said watch by a user and comprising at least one mobile transmitter arranged to be driven by said oscillating mass and arranged to cooperate without contact with at least one mobile receiver that includes a said winding mechanism.

L'invention concerne le domaine des montres mécaniques ou électroniques comportant des moyens de recharge en énergie par conversion de mouvements volontaires ou involontaires effectués par l'utilisateur.The invention relates to the field of mechanical or electronic watches comprising energy recharging means by conversion of voluntary or involuntary movements performed by the user.

Arrière-plan de l'inventionBackground of the invention

Les montres mécaniques sont souvent divisées en deux catégories: celles dont le remontage est réalisé manuellement, et celles possédant une masse oscillante permettant un remontage automatique.Mechanical watches are often divided into two categories: those whose winding is done manually, and those with an oscillating weight allowing automatic winding.

Si les montres de la seconde catégorie sont présentées comme étant plus avancées technologiquement, les montres manuelles possèdent de nombreux avantages encore aujourd'hui : un encombrement inférieur, le silence de fonctionnement par l'absence de bruit de roulement, l'absence de sensation de balourd au poignet, une visibilité complète du mouvement côté fond, et une moindre usure du barillet. De plus, certains utilisateurs sont attachés au rituel consistant à remonter manuellement leur montre.If the watches of the second category are presented as being more technologically advanced, the manual watches have many advantages even today: a smaller size, the silence of operation by the absence of rolling noise, the absence of sensation of unbalance on the wrist, complete visibility of the bottom side movement, and less wear on the barrel. In addition, some users are attached to the ritual of manually winding their watch.

Certains utilisateurs doivent donc faire un choix parfois difficile entre les aspects pratiques d'une montre à remontage automatique et les avantages traditionnels et émotionnels du remontage manuel. Il n'existe pas, sur le marché, de montre possédant soit un système, soit l'autre, au libre choix de l'utilisateur.Some users must therefore make a sometimes difficult choice between the practical aspects of a self-winding watch and the traditional and emotional advantages of manual winding. There is no watch on the market that has either a system or the other at the free choice of the user.

Les masses oscillantes de remontage automatique occupent, encore, un volume important à l'intérieur de la boîte, qui ne peut de ce fait contenir qu'un nombre limité de complications. C'est la raison pour laquelle les montres à grandes complications sont rarement des montres à remontage automatique.The oscillating masses of automatic winding still occupy a large volume inside the box, which can only contain a number limited number of complications. This is the reason why watches with big complications are rarely self-winding watches.

Ce téléphone combiné à une montre est monobloc ou articulé.The document WO2009 / 044027 A2 in the name of CELSIUS discloses a mobile phone, comprising a mechanical winding watch, where a mechanical reassembly device, disengageable in the closed position, exempts the user from manual winding by exploiting the kinetic energy, including the opening of the main valve or a cache battery, the sliding of a screen, access to a specific function by pivot or sliding of the watch, or the simple movement of the laptop, by a mechanism housed in a hinge or in a slide. This phone combined with a watch is monobloc or articulated.

Ce mécanisme peut aussi assurer le débrayage du mécanisme de remontage manuel.The document CH 705938 A1 in the name of ULYSSE NARDIN describes a timepiece comprising a planetary gear train for transferring energy from the input of the planetary gear train to the output of the planetary gear train, comprising a double-satellite planetary gear train, with a carrier arm of one or two cooperating solar wheels. each with a wheel or a crown oriented on the axis of rotation of the arm.

Il décrit aussi une montre comportant un remontoir automatique avec une masse oscillante comportant une première partie interne ferromagnétique et une deuxième partie périphérique en métal lourd, ou un disque conducteur paramagnétique coaxial à la masse oscillante.The document WO2014 / 166719 in the name of The SWATCH GROUP RESEARCH & DEVELOPMENT Ltd. discloses a static device for winding automatic watches, comprising a power supply means or an electric accumulator, and a receptacle support having a bearing surface for receiving the bottom of 'a watch. This device comprises means for generating a magnetic and / or electrostatic field arranged in a fixed position under the bearing surface and generating, at an angular sector of a substantially annular emission zone, a magnetic field or electrostatic direction orthogonal to the bearing surface, and of intensity and / or direction varying as a function of time.

Le document CH 706 352 A2 au nom de MONTRES BREGUET SA décrit une montre comportant, dans un boîtier étanche, un mobile d'entraînement d'un mécanisme de remontage statique, libre selon au moins un degré de liberté et comportant au moins une surface réceptrice mobile à proximité d'une surface d'extrémité du boîtier.

Le document FR 1 546 744 A au nom de MOUTSCHEN décrit une montre automatique, qui comporte un dispositif particulier de remontage avec suppression du remontoir mécanique traditionnel et du rouage de mise à l'heure. Le réglage de cette montre, notamment de la raquette, est possible par influence magnétique à travers la boîte, tout comme la commande d'un inverseur de remontage. Ce document cite, sans le détailler, un remontage mécano-magnétique, par une molette magnétique extérieure à la boîte, qui nécessite un mouvement manuel volontaire de mise en rotation analogue à celui appliqué à la molette d'un briquet, qui nécessite probablement l'enlèvement de la montre. Il s'agit donc d'un remontage manuel différent des systèmes connus.The document FR 1 546 744 A in the name of MOUTSCHEN describes an automatic watch, which includes a particular winding device with removal of the traditional mechanical winding and time setting wheel. The setting of this watch, including the racket, is possible by magnetic influence through the box, as the control of a winding inverter. This document cites, without detailing, a mechano-magnetic winding, by a magnetic knob outside the box, which requires a voluntary manual rotation movement similar to that applied to the knob of a lighter, which probably requires the removal of the watch. It is therefore a manual winding different from the known systems.

Description détaillée des modes de réalisation préférésDetailed Description of the Preferred Embodiments

L'invention se propose de réaliser un module additionnel de remontage automatique, amovible et apte à être très facilement installé ou déposé par l'utilisateur lui-même. Elle concerne toutes les montres comportant un mécanisme de remontage manuel, apte à stocker de l'énergie mécanique ou bien à convertir de l'énergie mécanique en énergie électrique. En particulier l'invention est très facilement applicable à toutes les montres comportant un mécanisme de remontage traditionnel, par une tige manoeuvrée par une couronne.The invention proposes to make an additional automatic winding module, removable and able to be very easily installed or deposited by the user himself. It concerns all watches comprising a manual winding mechanism, able to store mechanical energy or to convert mechanical energy into electrical energy. In particular the invention is very easily applicable to all watches with a traditional winding mechanism, by a rod operated by a crown.

Selon l'invention, la transformation d'une montre à armage manuel en montre à armage automatique s'exécute de façon simple: ajouter à la boîte de montre, au niveau du fond, de la lunette ou de sa périphérie, un module optionnel contenant au moins une masse oscillante.According to the invention, the transformation of a manual winding watch into a self-winding watch executes in a simple way: adding to the watch case, at the bottom, the bezel or its periphery, an optional module containing at least one oscillating mass.

De préférence, le système d'accouplement entre un réducteur du module optionnel et un réducteur du mécanisme de remontage, ou du mouvement, dans la boîte de montre est réalisé sans contact tel que présenté schématiquement aux figures 3 à 7.Preferably, the coupling system between a reducer of the optional module and a gearbox of the winding mechanism, or movement, in the watch case is made without contact as schematically presented to the Figures 3 to 7 .

Ainsi, l'invention concerne un ensemble constitué d'une montre et d'au moins un mécanisme additionnel de remontage automatique, la montre 1 comportant une boîte 10 renfermant un mouvement 20, et au moins un accumulateur d'énergie 30, qui est rechargé en énergie par au moins un mécanisme de remontoir 40. La montre 1 est agencée pour recevoir, fixé sur la boîte 10 ou sur un bracelet 50 ou sur un composant d'habillage 60 de la montre 1 disposé à proximité immédiate de la boîte 10, au moins un mécanisme additionnel de remontage automatique 100, qui est prévu pour être porté en même temps que la montre 1 par un utilisateur.Thus, the invention relates to a set consisting of a watch and at least one additional automatic winding mechanism, the watch 1 comprising a box 10 containing a movement 20, and at least one energy accumulator 30, which is recharged in energy by at least one winding mechanism 40. The watch 1 is arranged to receive, fixed on the box 10 or on a bracelet 50 or on a trim component 60 of the watch 1 disposed in the immediate vicinity of the box 10, at least one additional automatic winding mechanism 100, which is intended to be worn at the same time as the watch 1 by a user.

Dans une variante avantageuse de l'invention, ce mécanisme additionnel de remontage automatique 100 comporte au moins un mobile émetteur 110, qui est agencé pour coopérer sans contact avec au moins un mobile récepteur 41 que comporte un tel mécanisme de remontoir 40, dans une interaction à distance. Cette interaction à distance est réalisée sous l'action d'au moins un champ, dans l'entrefer E situé entre cet au moins un mobile émetteur 110 et cet au moins un mobile récepteur 41. L'intensité de cet au moins un champ, et la distance maximale d'entrefer E, sont définies pour permettre la transmission à au moins un mobile récepteur 41, pour la recharge en énergie d'au moins un accumulateur d'énergie 30, d'un couple ou un effort imprimé par un utilisateur à au moins un mobile émetteur 110.In an advantageous variant of the invention, this additional automatic winding mechanism 100 comprises at least one mobile transmitter 110, which is arranged to cooperate without contact with at least one mobile receiver 41 that includes such a winding mechanism 40, in an interaction remote. This remote interaction is carried out under the action of at least one field, in the air gap E situated between this at least one mobile transmitter 110 and this at least one mobile receiver 41. The intensity of this at least one field, and the maximum gap distance E, are defined to enable transmission to at least one mobile receiver 41, for the energy recharge of at least one energy accumulator 30, a couple or a user-printed effort at least one mobile transmitter 110.

Ce couple ou cet effort peut résulter d'un mouvement volontaire de l'utilisateur, comme la manoeuvre d'une lunette, d'un poussoir, ou autre, ou d'un mouvement involontaire, tel que mis à profit dans les mécanismes de remontage automatique par masse oscillante bien connus de l'homme du métier.This couple or this effort can result from a voluntary movement of the user, such as the operation of a telescope, a pusher, or other, or an involuntary movement, as used in the winding mechanisms automatic oscillating weight well known to those skilled in the art.

L'ensemble peut comporter plusieurs tels mécanismes additionnels de remontage automatique 100.The assembly may include several such additional mechanisms of automatic winding 100.

Selon l'invention, au moins un de ces mécanismes additionnels de remontage automatique 100 est amovible par rapport à la boîte 10.According to the invention, at least one of these additional automatic winding mechanisms 100 is removable relative to the box 10.

Dans une première variante de l'invention, la montre 1 est une montre mécanique ou électronique, dont le mouvement 20 est mécanique ou électronique, et dont au moins un accumulateur d'énergie 30 comporte au moins un barillet 31 à ressort.In a first variant of the invention, the watch 1 is a mechanical or electronic watch, the movement 20 of which is mechanical or electronic, and of which at least one energy accumulator 30 comprises at least one spring-loaded barrel 31.

Dans une autre variante de l'invention, la montre 1 est une montre électronique, dont le mouvement 20 est électronique ou électromécanique, et dont au moins un accumulateur d'énergie 30 est alimenté par un convertisseur d'énergie mécanique en énergie électrique.In another variant of the invention, the watch 1 is an electronic watch, whose movement is electronic or electromechanical, and of which at least one energy accumulator 30 is powered by a mechanical energy converter into electrical energy.

Dans une autre variante de l'invention, la montre 1 est une montre électronique, dont le mouvement 20 est électronique ou électromécanique, et dont au moins un accumulateur d'énergie 30 comporte au moins un barillet 31 à ressort.In another variant of the invention, the watch 1 is an electronic watch, the movement of which is electronic or electromechanical, and of which at least one energy accumulator 30 comprises at least one spring-loaded barrel 31.

Le champ permettant l'interaction à distance entre un mobile émetteur 110 et un mobile récepteur 41 est de préférence un champ magnétique, ou un champ électrostatique.The field allowing the remote interaction between a mobile transmitter 110 and a mobile receiver 41 is preferably a magnetic field, or an electrostatic field.

Dans les modes de réalisation particuliers illustrés par les figures, non limitatifs, la montre 1 comporte au moins un couple formé d'un tel mobile émetteur 110 et d'un tel mobile récepteur 41, dont au moins l'un des deux est aimanté. Le mobile émetteur 110 est aimanté ou ferromagnétique, et agencé pour coopérer en interaction magnétique avec le mobile récepteur 41 qui est ferromagnétique ou aimanté.In the particular embodiments illustrated by the nonlimiting figures, the watch 1 comprises at least one pair formed by such a mobile transmitter 110 and such a mobile receiver 41, at least one of which is magnetized. The mobile transmitter 110 is magnetized or ferromagnetic, and arranged to cooperate in magnetic interaction with the receiving mobile 41 which is ferromagnetic or magnetized.

Plus particulièrement, au sein d'au moins un tel couple, à la fois le mobile émetteur 110 et le mobile récepteur 41 sont aimantés, tel que visible sur les figures 1, 2, 9 et 10, où le mobile émetteur 110 comporte au moins une masse polaire émettrice 101, et où le mobile récepteur 41 comporte au moins une masse polaire réceptrice 401.More particularly, within at least one such pair, both the mobile transmitter 110 and the mobile receiver 41 are magnetized, as visible on the figures 1 , 2 , 9 and 10 , where the mobile transmitter 110 comprises at least one transmitting polar mass 101, and wherein the mobile receiver 41 comprises at least one receiving polar mass 401.

Le pivotement de ces mobiles n'est pas détaillé, la figure 1 montre un pivotement par roulement à billes 102, 402, du mobile émetteur 110 par rapport à un noyau 103 fixé par une vis 105 à un flasque 104, et le mobile récepteur 41 par rapport à un noyau 12 fixé à la boîte 10.The pivoting of these mobiles is not detailed, the figure 1 shows a ball-bearing pivoting 102, 402, of the mobile transmitter 110 relative to a core 103 fixed by a screw 105 to a flange 104, and the mobile receiver 41 relative to a core 12 fixed to the box 10.

Dans un premier mode de réalisation, tel que visible sur les figures 1, 2, et 9, au sein d'un tel couple, le mobile émetteur 110 et le mobile récepteur 41 présentent l'un à l'autre des masses polaires 101 et 401, qui comportent des surfaces d'entrefer 111, respectivement 411, sensiblement toutes parallèles entre elles et de polarités opposées. Si ces masses polaires sont en nombre égal et de répartition uniforme, elles tendent à s'aligner, tel que visible sur la figure 9.In a first embodiment, as visible on the figures 1 , 2 , and 9 within such a pair, the mobile transmitter 110 and the mobile receiver 41 have one another pole masses 101 and 401, which have air gap surfaces 111, respectively 411, substantially all parallel to each other and opposite polarities. If these polar masses are equal in number and of uniform distribution, they tend to align, as visible on the figure 9 .

Dans un autre mode de réalisation, tel que visible sur la figure 10, le mobile émetteur 110 et le mobile récepteur 41 présentent l'un à l'autre des masses polaires 101 et 401, qui comportent des surfaces d'entrefer 111, respectivement 411, sensiblement toutes parallèles entre elles et de même polarité. Les masses polaires tendent alors à se mettre en quinconce, tel que visible sur la figure 10.In another embodiment, as visible on the figure 10 , the mobile transmitter 110 and the mobile receiver 41 have one another pole masses 101 and 401, which have air gap surfaces 111, respectively 411, substantially all parallel to each other and the same polarity. The polar masses tend to become staggered, as visible on the figure 10 .

Mais on comprend qu'il suffit qu'une seule masse polaire émettrice 101 joue le rôle d'entraîneur d'une masse polaire réceptrice 411, à la façon d'un toc sur un tour, pour mettre le mobile récepteur 41 en mouvement. Bien entendu, meilleur est le couplage entre les masses polaires émettrices 101 et les masses polaires réceptrices 411, meilleur est l'entraînement réalisé, que ce couplage soit effectué en alignement comme sur la figure 9, ou en alternance sur la figure 10.But it is understood that it is sufficient that a single transmitting polar mass 101 acts as a trainer of a receiving polar mass 411, in the manner of a knock on a lathe, to put the mobile receiver 41 in motion. Of course, the better the coupling between the transmitting polar masses 101 and the receiving polar masses 411, the better the training carried out, whether this coupling is carried out in alignment as on the figure 9 , or alternately on the figure 10 .

Dans un mode particulier de réalisation, l'ensemble comporte au moins un couple formé d'un mobile émetteur 110 et d'un mobile récepteur 41, dans lequel couple la coopération se fait selon une direction axiale par rapport à un axe principal de la boîte 10.In a particular embodiment, the assembly comprises at least one pair formed of a mobile transmitter 110 and a mobile receiver 41, in which the couple is cooperating in an axial direction with respect to a main axis of the box. 10.

Les figures 1, 2, 9, et 10 illustrent des cas particuliers où les différentes lignes de champ sont parallèles entre elles, et de préférence parallèles à un axe principal que comporte la boîte 10, qui est l'axe du mouvement 20 si celui-ci est mécanique, l'axe principal d'aiguillage, ou encore un axe de symétrie d'une partie des usinages ou encore des fixations de bracelet par des cornes ou similaire. Cette configuration correspond aux exemples d'un positionnement axial du mécanisme additionnel de remontage automatique 100, illustrés aux figures 3 à 7.The figures 1 , 2 , 9, and 10 illustrate particular cases where the different field lines are parallel to each other, and preferably parallel to a main axis that includes the box 10, which is the axis of the movement 20 if it is mechanical, the main axis of referral, or an axis of symmetry of a part of the machining or bracelet attachments by horns or the like. This configuration corresponds to the examples of axial positioning of the additional automatic winding mechanism 100, illustrated in FIGS. Figures 3 to 7 .

D'autres géométries sont possibles, notamment le cas d'un mobile émetteur 110 et d'un mobile récepteur 41 tous deux annulaires, tel que visible sur la figure 7.Other geometries are possible, especially the case of a mobile transmitter 110 and a receiver mobile 41 both annular, as visible on the figure 7 .

Ainsi, dans un mode particulier de réalisation, l'ensemble comporte au moins un couple formé d'un mobile émetteur 110 et d'un mobile récepteur 41, qui sont sensiblement annulaires et coaxiaux par rapport à un axe principal de la boîte 10, dans lequel couple la coopération se fait tangentiellement par rapport à un cylindre ou un cône d'axe de révolution parallèle ou confondu avec l'axe principal de la boîte 10, de façon à permettre un remontage par une action volontaire ou involontaire de l'utilisateur.Thus, in a particular embodiment, the assembly comprises at least one pair formed of a mobile transmitter 110 and a mobile receiver 41, which are substantially annular and coaxial with respect to a main axis of the box 10, in which couples the cooperation is tangentially with respect to a cylinder or a cone axis of revolution parallel or coincident with the main axis of the box 10, so as to allow reassembly by a voluntary or involuntary action of the user.

La figure 8 illustre un exemple particulier d'une telle réalisation, où le mécanisme additionnel de remontage automatique 100 prend la forme d'une lunette rapportée autour de la boîte 10, et intégrant une masse oscillante annulaire 120. Avantageusement, cette lunette, est, encore, une lunette à crantage magnétique, telle que décrite dans la demande européenne EP14185439.8 au nom de MONTRES BREGUET SA. Il est alors possible de supprimer la couronne de remontage, qui pose chroniquement des problèmes d'étanchéité difficiles, notamment pour les montres de plongée. Il est à noter que les autres fonctions classiques, de mise à l'heure, de déclenchement de chronographe, de remise à zéro ou autres, peuvent être réalisées de façon similaire par des systèmes sans contact.The figure 8 illustrates a particular example of such an embodiment, where the additional mechanism of automatic winding 100 takes the form of a telescope attached around the box 10, and incorporating an annular oscillating mass 120. Advantageously, this telescope is, again, a magnetic bezel, as described in the European application EP14185439.8 in the name of MONTRES BREGUET SA. It is then possible to remove the winding crown, which chronically poses difficult sealing problems, especially for diving watches. It should be noted that the other conventional functions, time setting, chronograph trigger, reset or other, can be performed similarly by contactless systems.

L'utilisateur peut, ainsi, choisir de remonter sa montre, ou bien classiquement par la couronne, ou bien par rotation de la lunette, ou bien en la portant.The user can, thus, choose to reassemble his watch, or classically by the crown, or by rotating the bezel, or by wearing it.

Plus particulièrement encore, les différentes masses polaires peuvent être disposées radialement, ou encore tangentiellement, par rapport à un disque ou un anneau qui les porte. Ainsi, dans un cas particulier, au sein d'un tel couple, le mobile émetteur 110 comporte des masses polaires émettrices dont les lignes de champ principales sont coplanaires dans un plan émetteur, et le mobile récepteur 41 comporte des masses polaires réceptrices dont les lignes de champ principales sont coplanaires dans un plan récepteur, et où l'entrefer entre le mobile émetteur 110 et le mobile récepteur 41 est un volume cylindrique délimité par le plan émetteur et le plan récepteur qui sont parallèles l'un à l'autre.More particularly, the different polar masses may be arranged radially, or tangentially, with respect to a disk or a ring that carries them. Thus, in a particular case, within such a pair, the mobile transmitter 110 comprises transmitting polar masses whose main field lines are coplanar in a transmitter plane, and the mobile receiver 41 comprises polar receptor masses whose lines main fields are coplanar in a receiver plane, and where the air gap between the mobile transmitter 110 and the mobile receiver 41 is a cylindrical volume defined by the emitter plane and the receiving plane which are parallel to each other.

Bien d'autres configurations sont possibles, elles sont dictées au constructeur par l'espace disponible dans la boîte 10. Un des buts de l'invention est de libérer une montre mécanique, de type à remontage automatique par masse oscillante, de l'important volume occupé par cette dernière, par report de cette fonction à l'extérieur de la boîte de montre. Il s'agit donc de privilégier, pour le positionnement du ou des mobiles récepteurs 41, l'utilisation d'espaces peu propices à la réception de complications ou d'accessoires.Many other configurations are possible, they are dictated to the manufacturer by the space available in the box 10. One of the aims of the invention is to release a mechanical watch, self-winding type by oscillating weight, the important volume occupied by the latter, by carrying this function outside the watch box. It is therefore a question of privileging, for the positioning the mobile receiver or 41, the use of spaces not conducive to the receipt of complications or accessories.

Tel que visible sur les figures 1, 2, 6, 7, et 8, le mécanisme additionnel de remontage automatique 100 comporte avantageusement au moins une masse oscillante 120, qui est mobile sous l'action des mouvements de l'utilisateur de l'ensemble, et qui constitue un tel mobile émetteur 110 comme sur les figures 1 et 6, ou qui constitue des moyens d'entraînement pour l'entraînement en pivotement ou en rotation ou en translation d'au moins un tel mobile émetteur 110 comme sur les figures 2 et 7, où la masse oscillante 120 engrène avec un réducteur 114, qui constitue le mobile émetteur 110.As visible on the figures 1 , 2 , 6, 7, and 8 the additional automatic winding mechanism 100 advantageously comprises at least one oscillating mass 120, which is movable under the action of the movements of the user of the assembly, and which constitutes such a mobile transmitter 110 as on the figures 1 and 6 , or which constitutes driving means for driving in pivoting or in rotation or in translation of at least one such mobile transmitter 110 as on the figures 2 and 7 , where the oscillating mass 120 meshes with a reducer 114, which constitutes the mobile transmitter 110.

De préférence, au moins un mobile émetteur 110 comporte une piste émettrice 111 qui est agencée pour être positionnée au plus près d'une piste réceptrice 411 d'un tel mobile récepteur 41.Preferably, at least one mobile transmitter 110 comprises a transmitting track 111 which is arranged to be positioned as close as possible to a reception track 411 of such a mobile receiver 41.

De préférence, tel que visible sur la figure 2, le mécanisme de remontoir 40 comporte, en aval d'un rochet 42 alimentant directement en énergie un tel accumulateur d'énergie 30, un rouage démultiplicateur 43 qui comporte, à l'opposé de ce rochet 42, des moyens de débrayage 44, par friction ou autre, en aval desquels est situé au moins un tel mobile récepteur 41, à proximité directe de la périphérie intérieure de la boîte 10. Dans la variante des figures 1 et 2, le mobile récepteur 41 est au plus près d'un fond 15, qui est avantageusement transparent pour laisser voir le mécanisme. Le mécanisme de remontoir 40 peut comporter tout composant classique d'un mécanisme de remontage automatique, comme des roues inverseuses, un cliquet, bien connus de l'homme du métier.Preferably, as visible on the figure 2 , the winding mechanism 40 comprises, downstream of a ratchet 42 directly supplying energy such an energy accumulator 30, a gear wheel 43 which comprises, opposite this ratchet 42, disengaging means 44, by friction or other, downstream of which is located at least one such mobile receiver 41, close to the inner periphery of the box 10. In the variant of figures 1 and 2 , the receiving mobile 41 is as close to a bottom 15, which is advantageously transparent to show the mechanism. The winding mechanism 40 may comprise any conventional component of an automatic winding mechanism, such as inverting wheels, a ratchet, well known to those skilled in the art.

Dans une variante particulière, le mécanisme de remontoir 40 comporte un tel rochet 42 alimentant directement en énergie un accumulateur d'énergie 30, et qui constitue un mobile récepteur 41. Cette solution semble peu avantageuse en raison de l'absence de démultiplication, comparée à la variante comportant un rouage démultiplicateur 43, mais elle est toutefois utilisable, dans la mesure où le couple transmissible par l'interaction sans contact est suffisant pour remonter directement le barillet et que l'énergie transformée par le mouvement d'une masse oscillante est toujours excédentaire par rapport aux capacités de stockage d'un barillet.In a particular variant, the winding mechanism 40 comprises such a ratchet 42 directly supplying energy to an energy accumulator 30, and which constitutes a mobile receiver 41. This solution seems to be of little advantage because of the absence of gear reduction, compared to the variant comprising a reduction gear train 43, but it is however usable, insofar as the torque transmissible by the contactless interaction is sufficient to directly go up the barrel and the energy transformed by the movement of an oscillating weight is always excess in relation to the storage capacities of a cylinder.

L'invention permet de dégager une grande partie du volume intérieur de la boîte 10, qui ne doit plus être réservé à une masse oscillante, et d'accueillir d'autres fonctionnalités ou complications, par exemple sous forme de modules additionnels. Tout particulièrement, il est possible d'implanter un module sonore ou musical, comportant un barillet de sonnerie ou similaire, qui peut avantageusement être lui aussi alimenté en énergie par un mécanisme additionnel de remontage automatique 100 selon l'invention.The invention makes it possible to free up a large part of the internal volume of the box 10, which must no longer be reserved for an oscillating weight, and to accommodate other functionalities or complications, for example in the form of additional modules. In particular, it is possible to implement a sound or musical module, comprising a ringer barrel or the like, which can advantageously also be supplied with energy by an additional automatic winding mechanism 100 according to the invention.

De ce fait, il est souvent avantageux de montrer à l'utilisateur les mécanismes en fonctionnement à l'intérieur de la boîte 10. A cet effet, quand le mécanisme additionnel de remontage automatique 100 est plaqué sur le fond de la boîte 10, cette dernière comporte de préférence un fond 15 transparent, et le mécanisme additionnel de remontage automatique 100 comporte, de part et d'autre de la totalité des mobiles émetteurs 110 qu'il comporte, au moins deux glaces 115, 116 dont au moins l'une est agencée pour être disposée au plus près du fond 15 transparent, tel que visible sur les figures 1 et 2. Il est ainsi possible de visualiser à la fois les mécanismes contenus dans la boîte 10, et le contenu du mécanisme additionnel de remontage automatique 100 lui-même.Therefore, it is often advantageous to show the user the mechanisms in operation inside the box 10. For this purpose, when the additional automatic winding mechanism 100 is pressed against the bottom of the box 10, this the latter preferably has a transparent bottom, and the additional automatic winding mechanism 100 comprises, on either side of all of the emitters 110 that it comprises, at least two windows 115, 116 of which at least one is arranged to be arranged as close as possible to the transparent bottom, as visible on the figures 1 and 2 . It is thus possible to visualize both the mechanisms contained in the box 10, and the contents of the additional automatic winding mechanism 100 itself.

La boîte 10 comporte des moyens d'assemblage 13, et au moins un mécanisme additionnel de remontage automatique 100 comporte des moyens d'assemblage complémentaire 113 pour son positionnement et sa solidarisation sécurisée sur la boîte 10. La partie gauche de la figure 1 illustre un exemple de fixation par vissage entre un filetage 13A et un taraudage 113A, tandis que la partie droite de la même figure illustre un exemple de fixation clipée entre deux lèvres complémentaires 13B et 113B.The box 10 comprises assembly means 13, and at least one additional automatic winding mechanism 100 comprises complementary assembly means 113 for its positioning and secure fastening on the box 10. The left part of the figure 1 illustrates an example of fastening by screwing between a thread 13A and a thread 113A, while the right part of the same figure shows an example of clip fastening between two complementary lips 13B and 113B.

Dans une réalisation particulière, la boîte 10 comporte des moyens d'indexage 12 et de tels moyens d'assemblage 13, et au moins un mécanisme additionnel de remontage automatique 100 comporte des moyens d'indexage complémentaire 112 et des moyens d'assemblage complémentaire 113 pour son positionnement et sa solidarisation sécurisée sur la boîte 10. Une réalisation particulière, nullement limitative, est du type de fixation à baïonnette similaire à celle d'un objectif d'appareil photographique, avec un positionnement relatif en alignement de repères complémentaires qui sont ces moyens d'indexage 12 et ces moyens d'indexage complémentaire 112, une insertion frontale, et une rotation jusqu'à une position de verrouillage sur une bille à ressort ou similaire. La figure 2 illustre un autre exemple de fixation clipée, avec une lèvre 13 en section de sapin coopérant avec un logement 113 comportant plusieurs gorges parallèles.In a particular embodiment, the box 10 comprises indexing means 12 and such assembly means 13, and at least one additional automatic winding mechanism 100 comprises complementary indexing means 112 and complementary assembly means 113 for its positioning and secure fastening on the box 10. A particular embodiment, in no way limiting, is the type of bayonet attachment similar to that of a camera lens, with a relative positioning in alignment complementary marks which are these indexing means 12 and these complementary indexing means 112, a front insertion, and a rotation to a locking position on a spring ball or the like. The figure 2 illustrates another example of clip fastening, with a lip 13 in fir section cooperating with a housing 113 having a plurality of parallel grooves.

Un avantage de l'invention consiste dans le caractère amovible du mécanisme additionnel de remontage automatique 100, qui autorise des interventions plus faciles à l'intérieur de la boîte 10, dont l'accès peut être facilement libéré. Toutefois, il peut se révéler avantageux, et tout particulièrement quand l'ensemble comporte plusieurs mécanismes additionnels de remontage automatique 100, qu'au moins un de ces mécanismes additionnels de remontage automatique 100 soit fixé à la boîte 10 de façon indémontable.An advantage of the invention consists in the removable nature of the additional automatic winding mechanism 100, which allows easier interventions inside the box 10, whose access can be easily released. However, it may be advantageous, and especially when the assembly comprises several additional mechanisms of automatic winding 100, at least one of these additional mechanisms of automatic winding 100 is fixed to the box 10 in a way that can not be dismantled.

De façon particulière et avantageuse, le mécanisme additionnel de remontage automatique 100 constitue un bloc amovible étanche exempt de toute ouverture. Cette étanchéité est notamment assurée par des joints 106, 107. Le bloc amovible peut, encore, être complètement soudé ou collé sur toute sa périphérie, et nulle intervention n'est plus nécessaire, ni même possible, à l'intérieur de ce bloc.Particularly and advantageously, the additional mechanism of automatic winding 100 constitutes a removable removable block without any opening. This sealing is in particular provided by seals 106, 107. The removable block may, again, be completely welded or bonded over its entire periphery, and no intervention is necessary, or even possible, within this block.

De façon particulière la boîte 10 constitue un bloc étanche exempt de toute ouverture. Particulièrement, des moyens d'étanchéité 11 relient le fond 15 et la boîte 10.In particular, the box 10 constitutes a sealed block free of any opening. In particular, sealing means 11 connect the bottom 15 and the box 10.

En somme, le mécanisme additionnel de remontage automatique 100 que comporte un ensemble selon l'invention, est conçu en tant que module additionnel et optionnel, permettant de déporter une fonction de remontage automatique à l'extérieur de la boîte 10 de montre, et donc, dans l'élaboration de variantes sur la base d'une montre existante, de libérer de la boîte 10 l'espace habituellement dévolu à la masse oscillante, et d'utiliser cet espace pour loger d'autres complications ou amincir de manière significative le produit.In sum, the additional automatic winding mechanism 100 that comprises an assembly according to the invention, is designed as an additional and optional module, allowing to deport an automatic winding function outside the watch box, and therefore in the development of variants based on an existing watch, to release from the box 10 the space usually devolved to the oscillating weight, and to use this space to accommodate other complications or significantly thin the product.

L'avantage d'un système d'accouplement sans contact, notamment magnétique, est qu'il supprime toute complexité d'ajout du module de remontage automatique par l'utilisateur. L'opération ne risque pas d'influencer l'étanchéité de la montre, car il n'y a aucune opération à effectuer sur la boîte de montre. L'accouplement magnétique peut être réalisé avec des aimants en attraction ou en répulsion. Un blindage additionnel optionnel, et recommandé, permet de fermer le circuit magnétique et de minimiser les fuites.The advantage of a contactless coupling system, particularly magnetic, is that it eliminates the complexity of adding the automatic winding module by the user. The operation does not affect the tightness of the watch, because there is no operation to be performed on the watch case. The magnetic coupling can be achieved with magnets in attraction or repulsion. Optional additional shielding is recommended to close the magnetic circuit and minimize leakage.

Le dimensionnement d'un tel accouplement magnétique, avec des mobiles émetteurs et récepteur de petite taille, typiquement d'un diamètre de l'ordre de 10 mm, comportant de préférence de 3 à 12 aimants néodyme-fer-bore, est parfaitement compatible avec un fonctionnement optimal lors des petites accélérations typiques d'un porter normal. Même si l'accouplement magnétique peut être sujet à un décrochage en cas d'accélération brusque, il n'y a aucun dommage, puisque tout au plus la montre n'est pas réarmée lors des premiers tours à haute vitesse de la masse oscillante. Il est connu qu'en pratique, une montre à remontage automatique au porter est souvent armée au maximum, on peut tolérer un système moins efficace que l'accouplement mécanique. Dans un tel cas de figure, la bride glissante traditionnelle des ressorts de barillet automatique peut être supprimée, ce qui représente un avantage.The sizing of such a magnetic coupling, with small emitter and receiver mobiles, typically with a diameter of the order of 10 mm, preferably comprising from 3 to 12 neodymium-iron-boron magnets, is perfectly compatible with optimal operation during small accelerations typical of a normal wear. Even though the magnetic coupling can being subject to a stall in case of sudden acceleration, there is no damage, since at most the watch is not rearmed during the first high-speed turns of the oscillating weight. It is known that in practice, a self-winding watch to wear is often armed to the maximum, we can tolerate a system less effective than the mechanical coupling. In such a case, the traditional slipping flange of the automatic barrel springs can be omitted, which is an advantage.

Dans une autre variante, le système d'accouplement entre un réducteur du module optionnel et un réducteur du mécanisme de remontage, ou du mouvement, dans la boîte de montre est réalisé par un mécanisme additionnel de remontage automatique, qui comporte un couplage mécanique direct, par pignon, engrenage ou similaire. L'agencement interne du mécanisme additionnel peut être le même que celui décrit ci-dessus pour la variante sans contact, notamment avec une masse oscillante. Le mobile émetteur 110 est alors remplacé par un mobile d'entraînement, qui coopère en entraînement mécanique classique avec un mobile d'entrée situé dans la montre, et qui remplace le mobile récepteur 41.In another variant, the coupling system between a gearbox of the optional module and a gearbox of the winding mechanism, or of the movement, in the watch case is made by an additional automatic winding mechanism, which comprises a direct mechanical coupling, by gear, gear or the like. The internal arrangement of the additional mechanism may be the same as that described above for the non-contact variant, in particular with an oscillating mass. The mobile transmitter 110 is then replaced by a drive mobile, which cooperates in conventional mechanical drive with an input mobile located in the watch, and which replaces the mobile receiver 41.
