Un exemple de réalisation d'un dispositif de remontage d'un ressort de barillet d'un mouvement d'une pièce d'horlogerie par l'intermédiaire de la couronne, désigné par la référence générale 1 va maintenant être décrit dans ce qui suit faisant référence conjointement aux figures 1, 2 et 3a à 3c.An exemplary embodiment of a device for winding a mainspring of a movement of a timepiece through the crown, designated by the general reference 1 will now be described in the following making reference jointly to Figures 1, 2 and 3a to 3c .

Comme précédemment évoqué, le principe général de l'invention repose sur la mise en oeuvre d'un dispositif 1 de remontage portable permettant de remonter le ressort d'un barillet via la couronne C d'une montre à remontage manuelle ou automatique, représentée schématiquement à la figure 1.As previously mentioned, the general principle of the invention is based on the implementation of a device 1 for portable winding to raise the spring of a barrel via the crown C of a manual or automatic winding watch, shown schematically to the figure 1 .

Dans cet exemple, le dispositif 1 est composé d'un corps 10 présentant au moins deux logements 110 et 112 destinés à recevoir respectivement un moteur 11 électrique à courant continu, un dispositif d'alimentation, en l'occurrence une batterie 12 qui peut être rechargeable ou non, ainsi qu'un circuit électronique 16 de commande disposé à l'une des extrémités du corps 10. Le dispositif d'alimentation est agencé pour alimenter le circuit électronique de commande ainsi que le moteur électrique 11. Dans une variante, la batterie pourrait être remplacée par une entrée d'alimentation reliée au secteur par un cordon de raccordement électrique via un convertisseur de courant alternatif en courant continu intégré ou non au dispositif de remontage.In this example, the device 1 is composed of a body 10 having at least two housings 110 and 112 intended to receive respectively a DC electric motor 11, a supply device, in this case a battery 12 which can be rechargeable or not, and an electronic control circuit 16 disposed at one end of the body 10. supply device is arranged to supply the electronic control circuit as well as the electric motor 11. In a variant, the battery could be replaced by a power input connected to the mains by an electrical connection cord via an AC power converter. in direct current integrated or not to the device of reassembly.

Comme on peut l'observer sur les figures 1 et 2, le corps 10 est de forme générale cylindrique et peut s'ouvrir en deux parties ou demi-coques 10a, 10b suivant la longueur du dispositif 1, les deux parties reliées entre elles par exemple au moyen de vis (non représentées). Alternativement les deux demi-coques formant le corps 10 peuvent être articulées l'une sur l'autre pour faciliter le changement de pièces composant le dispositif.As can be seen on the Figures 1 and 2 , the body 10 is generally cylindrical in shape and can open in two parts or half-shells 10a, 10b along the length of the device 1, the two parts interconnected for example by means of screws (not shown). Alternatively the two half-shells forming the body 10 can be hinged to each other to facilitate the change of component parts of the device.

Le corps 10 peut être réalisé dans un matériau plastique, voire dans un matériau métallique. On comprendra ici que d'autres matériaux auraient pu être envisagés par l'homme du métier dans le cadre de la présente invention.The body 10 may be made of a plastic material, or even of a metallic material. It will be understood here that other materials could have been envisaged by those skilled in the art within the context of the present invention.

Dans cet exemple, le dispositif 1 comprend également des moyens d'entraînement 19 de la couronne disposés à l'autre extrémité libre du corps 10 du dispositif 1, à savoir l'extrémité opposée à celle recevant le circuit électronique 16 de commande.

A luminous display, such as an LED (light-emitting diode), for example, indicates the state of charge of the battery 12.

Selon l'invention, le dispositif 1 comprend un ressort 15 positionné entre la batterie 12 et le moteur 11 pour permettre au moteur 11 de coulisser dans son logement 110, avec les moyens d'entraînement 19, le moteur 11 et le logement 110 étant configurés pour que le moteur puisse être guidé et coulissé selon l'axe longitudinal du corps entre au moins deux positions. Avantageusement, le corps 1 peut présenter un logement de forme cylindrique destiné à recevoir le ressort 15, et disposé entre les logements 110 et 112 du moteur 11 et de la batterie 12.According to the invention, the device 1 comprises a spring 15 positioned between the battery 12 and the motor 11 to allow the motor 11 to slide in its housing 110, with the drive means 19, the motor 11 and the housing 110 being configured so that the motor can be guided and slid along the longitudinal axis of the body between at least two positions. Advantageously, the body 1 may have a cylindrical housing for receiving the spring 15, and disposed between the housings 110 and 112 of the motor 11 and the battery 12.

Comme on peut l'observer sur les figures, la batterie 12, le moteur 11, le ressort 15, les moyens d'entrainement 19 et l'embout creux 14 sont alignés selon un même axe traversant le corps 10 du dispositif 1 selon sa longueur. Une telle disposition des éléments constitutifs du dispositif 1 permet d'obtenir un dispositif compact et facilement manipulable.As can be seen in the figures, the battery 12, the motor 11, the spring 15, the drive means 19 and the hollow end 14 are aligned along the same axis passing through the body 10 of the device 1 along its length . Such an arrangement of the constituent elements of the device 1 makes it possible to obtain a compact and easily manipulable device.

Selon l'exemple illustré, le dispositif comprend un interrupteur 18 disposé au sein du corps 1 du dispositif 10 et coopérant avec un deuxième circuit électronique, dit circuit moteur 17, assujetti au moteur et coulissant avec le moteur 11.According to the illustrated example, the device comprises a switch 18 disposed within the body 1 of the device 10 and cooperating with a second electronic circuit, said motor circuit 17, secured to the motor and sliding with the motor 11.

Le circuit moteur 17 comprend un contact 17a d'interrupteur coopérant avec une lame de contact 18a formant un interrupteur 18, qui peut être ouvert et/ou fermé de façon à alimenter et/ou couper ledit moteur 11.The motor circuit 17 comprises a switch contact 17a cooperating with a contact blade 18a forming a switch 18, which can be opened and / or closed so as to power and / or cut said motor 11.

Comme on peut l'observer sur la figure 2, la lame 18a de l'interrupteur 18 s'étend le long du logement 112 de la batterie et du logement 110 du moteur 11, l'une des extrémités de la lame 18a étant à proximité immédiate du contact 17a du circuit moteur 17, et l'autre extrémité étant en contact avec l'un des pôles, positif ou négatif, de la batterie 12 au niveau du circuit électronique 16 de commande.As can be seen on the figure 2 , the blade 18a of the switch 18 extends along the housing 112 of the battery and the housing 110 of the motor 11, one end of the blade 18a being in the immediate vicinity of the contact 17a of the motor circuit 17, and the other end being in contact with one of the poles, positive or negative, of the battery 12 at the electronic control circuit 16.

Selon l'invention, le moteur 11 et les moyens d'entraînement 19 peuvent coulisser d'une position dite de repos, visible à la figure 3a, dans laquelle l'interrupteur 18 est ouvert (contact 17a éloigné de la lame 18a) et le moteur 11 n'est pas alimenté, vers une position dite de fonctionnement, visible à la figure 2b, dans laquelle l'interrupteur 18 est fermé (contact 17a en contact avec la lame 18a) et le moteur 11 est alimenté.According to the invention, the motor 11 and the drive means 19 can slide from a so-called rest position, visible to the figure 3a , in which the switch 18 is open (contact 17a remote from the blade 18a) and the motor 11 is not powered, to a so-called operating position, visible at the figure 2b in which the switch 18 is closed (contact 17a in contact with the blade 18a) and the motor 11 is energized.

Le passage de la position de repos vers la position de fonctionnement est obtenu en pressant les moyens d'entrainement 19 contre la couronne de la montre de manière à déplacer le moteur 11 et contraindre le ressort 15 pour que le contact 17a du circuit moteur 17 entre en contact avec la lame 18a de l'interrupteur 18 et que le moteur 11 soit alimenté pour enclencher la rotation des moyens d'entrainement 19.The transition from the rest position to the operating position is obtained by pressing the drive means 19 against the crown of the watch so as to move the motor 11 and constrain the spring 15 so that the contact 17a of the motor circuit 17 between in contact with the blade 18a of the switch 18 and that the motor 11 is energized to engage the rotation of the drive means 19.

Selon un mode de réalisation particulier de l'invention visible à la figure 3c, le moteur 11 présente une troisième position dans laquelle le moteur 11 n'est pas alimenté lorsque la pression exercée sur les moyens d'entraînement 19 dépasse un seuil prédéterminé. Un tel cas de figure peut par exemple se présenter lorsque l'utilisateur exerce une pression trop importante sur la couronne.According to a particular embodiment of the invention visible to the figure 3c , the motor 11 has a third position in which the motor 11 is not energized when the pressure exerted on the drive means 19 exceeds a predetermined threshold. Such a case may for example occur when the user exerts too much pressure on the crown.

Tel qu'illustré aux figures 1 et 2, les moyens d'entraînement 19 comprennent un embout creux 14 destiné à coopérer avec la couronne, l'embout creux 14 présentant une cavité 140 pour réceptionner la couronne de la montre.As illustrated in Figures 1 and 2 , the drive means 19 comprise a hollow end 14 intended to cooperate with the ring, the hollow end 14 having a cavity 140 for receiving the crown of the watch.

Avantageusement, l'embout creux 14 peut être réalisé en un matériau élastomère présentant un coefficient de frottement suffisamment élevé pour entrainer en rotation la couronne de la montre lorsque le moteur 11 est en position de fonctionnement ou comportant une forme adaptée à la couronne.Advantageously, the hollow end 14 may be made of an elastomeric material having a coefficient of friction sufficiently high to rotate the crown of the watch when the motor 11 is in the operating position or having a shape adapted to the crown.

Selon un mode de réalisation de l'invention, l'embout creux 14 peut être relié aux moyens d'entrainement 19 de manière amovible de façon à pouvoir monter différents embouts sur le dispositif 1 et ainsi s'adapter à tout type de couronne, notamment aux différents diamètres existants.According to one embodiment of the invention, the hollow end 14 can be connected to the drive means 19 removably so as to mount different end pieces on the device 1 and thus adapt to any type of crown, in particular to the different diameters existing.

Dans cet exemple, le circuit électronique 16 de commande comprend des moyens limiteurs de couple et/ou des moyens compteurs de tours afin d'éviter de forcer sur la couronne de la montre lorsque le ressort du barillet est remonté. Typiquement les valeurs limites de couple sont comprises entre 10 mNm et 50 mNm Ces valeurs sont de préférence réglables et seront ajustées par le constructeur ou le fabricant en fonction du type de montre à remonter.In this example, the electronic control circuit 16 comprises torque limiting means and / or lap counter means in order to avoid forcing on the crown of the watch when the spring of the barrel is raised. Typically the torque limit values are between 10 mNm and 50 mNm These values are preferably adjustable and will be adjusted by the manufacturer or the manufacturer depending on the type of watch to be reassembled.

Avantageusement, les moyens limiteurs de couple et/ou lesdits moyens compte tours peuvent être associés à des moyens d'affichage tel qu'un écran LCD affichant les différentes informations liées au couple de remontage et/ou au nombre de tours.Advantageously, the torque limiting means and / or said revolving means can be associated with display means such as an LCD screen displaying the various information related to the winding torque and / or the number of revolutions.

Le dispositif de remontage 1 selon l'invention fonctionne comme suit. L'utilisateur saisit le dispositif 1 de remontage dans une main et une pièce d'horlogerie, telle qu'une montre manuelle, dans l'autre main. L'utilisateur positionne alors la couronne de la pièce d'horlogerie au niveau de l'embout creux 14 de sorte que la couronne vienne se loger dans la cavité 140. Le moteur 11 est alors en position de repos comme illustré à la figure 3a.The winding device 1 according to the invention operates as follows. The user enters the winding device 1 in one hand and a timepiece, such as a manual watch, in the other hand. The user then positions the crown of the timepiece at the hollow end 14 so that the crown comes to be housed in the cavity 140. The motor 11 is then in the rest position as illustrated in FIG. figure 3a .

L'utilisateur presse ensuite le dispositif 1, et en particulier l'embout creux 14, en direction de la couronne de la montre de manière que le moteur 11 passe en positon de fonctionnement comme illustré à la figure 3b. Lorsque l'utilisateur presse l'embout creux 14 du dispositif 1 contre la couronne de la montre, cela a pour effet de déplacer les moyens d'entrainement 19 et le moteur 11 et de contraindre le ressort 15 jusqu'à ce que le contact 17a du circuit moteur 17 vienne en contact avec la lame 18a fermant ainsi l'interrupteur 18. Le moteur 11 est alors alimenté par la batterie 12 et enclenche la rotation de l'embout creux 14.The user then presses the device 1, and in particular the hollow end 14, in the direction of the crown of the watch so that the motor 11 goes into operation position as shown in FIG. figure 3b . When the user presses the hollow end 14 of the device 1 against the crown of the watch, this has the effect of moving the drive means 19 and the motor 11 and to constrain the spring 15 until the contact 17a of the motor circuit 17 comes into contact with the blade 18a thus closing the switch 18. The motor 11 is then powered by the battery 12 and triggers the rotation of the hollow end 14.

L'utilisateur peut alors maintenir le moteur 11 en position de fonctionnement jusqu'à ce que la couronne ait effectué le nombre de tours nécessaires au remontage complet du barillet de la montre. Une fois ce nombre de tours atteint, le système électronique détecte soit que le couple maximum prédéfini est atteint (puisque la couronne est bloquée car le ressort est remonté complétement) soit que le nombre de tours correspond à un nombre de tours prédéfini, et coupe l'entrainement du moteur qui se déclenche. L'utilisateur relâche alors la pression exercée contre la couronne de manière que le ressort 15 repousse le moteur 11 dans sa position de repos et ainsi coupe l'alimentation en rompant le contact entre le contact 17a du circuit moteur 17 et la lame 18a de l'interrupteur 18.The user can then maintain the engine 11 in the operating position until the crown has made the number of revolutions necessary for complete winding of the watch cylinder. Once this number of turns has been reached, the electronic system detects that the torque predefined maximum is reached (since the crown is locked because the spring is raised completely) or the number of revolutions corresponds to a predefined number of revolutions, and cuts the motor drive which is triggered. The user then releases the pressure exerted against the ring so that the spring 15 pushes the motor 11 back to its rest position and thus cuts off the supply by breaking the contact between the contact 17a of the motor circuit 17 and the blade 18a of the switch 18.

Grâce à ces différents aspects de l'invention, on dispose d'un dispositif 1 de remontage aisé à manipuler et à utiliser pour un utilisateur, et dont il n'est pas nécessaire de manipuler un interrupteur pour l'actionner.Thanks to these different aspects of the invention, there is a device 1 for easy winding to handle and use for a user, and it is not necessary to manipulate a switch to operate.

Naturellement, d'autres modes de réalisation auraient pu être envisagés par l'homme du métier sans pour autant sortir du cadre de l'invention définie par les revendications ci-après.Naturally, other embodiments could have been envisaged by those skilled in the art without departing from the scope of the invention defined by the claims below.
