DESCRIPTION DETAILLEEDETAILED DESCRIPTION

La présente invention procède de l'idée générale inventive qui consiste à procurer un système de lunette tournante étant plus simple à monter.The present invention proceeds from the general inventive idea of providing a rotating bezel system which is easier to assemble.

Les figures 1 et 2 montrent un élément d'habillage 10 telle une lunette 100 selon l'invention, cette lunette 100 étant montée sur une pièce d'horlogerie 1 comprend un boitier 2 fermé par un fond 3 et une glace 4. Cette lunette 100 est une pièce de forme annulaire qui comprend une face supérieure 100a visible par l'utilisateur et une face inférieure 100b. Cette lunette 100 pourra être réalisée dans un matériau plastique ou céramique ou tout autre matériau non électriquement conducteur.The Figures 1 and 2 show a covering element 10 such as a telescope 100 according to the invention, this telescope 100 being mounted on a timepiece 1 comprises a housing 2 closed by a bottom 3 and a window 4. This bezel 100 is a piece of shape annular which comprises an upper face 100a visible by the user and a lower face 100b. This bezel 100 may be made of a plastic or ceramic material or any other non-electrically conductive material.

Cette lunette 100 peut être montée tournante ou non au niveau de la carrure. Dans le cas d'une lunette 100 tournante, un ensemble ressort-crantage ou système à encliquetage (non représenté) est agencé. Cet ensemble ressort-crantage comprend des moyens ressorts et un élément denté. Un des éléments de l'ensemble ressort-crantage sera angulairement solidaire de la carrure alors que l'autre sera angulairement solidaire de la lunette 100 de sorte à permettre l'indexation angulaire de la lunette par rapport à la carrure.This bezel 100 can be rotatably mounted or not at the middle. In the case of a rotating bezel 100, a spring-notch or snap-in system (not shown) is provided. This spring and notch assembly comprises spring means and a toothed element. One of the elements of the spring-notch assembly will be angularly secured to the middle part while the other will be angularly integral with the bezel 100 so as to allow the angular indexing of the bezel relative to the middle part.

Pour le montage de la lunette 100, la pièce d'horlogerie comprend une carrure 20 dans laquelle un épaulement 21 est agencé, cet épaulement 21 étant défini par une paroi latérale 22 et une base 23. Cet épaulement sert de logement pour la lunette. En général, la paroi latérale 22 comprend une excroissance 24 s'étendant sur l'intégralité du périmètre de la paroi latérale 22. Cette excroissance 24 permet de définir, en coopération avec la base 23 et la paroi 22, une gorge de maintien 25. Cette gorge de maintien 25 permet, lors de l'assemblage à force de la lunette, que celle-ci s'y insère et soit maintenu.For the mounting of the telescope 100, the timepiece comprises a caseband 20 in which a shoulder 21 is arranged, this shoulder 21 being defined by a side wall 22 and a base 23. This shoulder serves as a housing for the telescope. In general, the side wall 22 comprises an outgrowth 24 extending over the entire perimeter of the side wall 22. This protrusion 24 makes it possible to define, in cooperation with the base 23 and the wall 22, a retaining groove 25. This holding groove 25 allows, during assembly by force of the bezel, that it is inserted and is maintained.

Avantageusement selon l'invention, la lunette 100 est munie d'un circuit de communication 102 comme visible aux figures 2 et 3. Pour cela, la lunette est réalisée de sorte à être munie d'une rainure 104 au niveau de la face supérieure 100a, cette rainure 104 étant également annulaire c'est à dire s'étendant le long de la face supérieure 100a. Un circuit de communication 102 comprend un support c'est-à-dire un circuit imprimé dont la forme est similaire à celle de la rainure 104 agencée sur la lunette c'est-à-dire une forme de bague. Dans le cas présent, le circuit imprimé sert de substrat pour une antenne en spirale et les différents composants électroniques permettant le fonctionnement du système y sont agencés.Advantageously according to the invention, the telescope 100 is provided with a communication circuit 102 as visible to the Figures 2 and 3 . For this, the bezel is made so as to be provided with a groove 104 at the upper face 100a, this groove 104 also being annular, ie extending along the upper face 100a. A communication circuit 102 comprises a support that is to say a printed circuit whose shape is similar to that of the groove 104 arranged on the bezel, that is to say a ring shape. In this case, the printed circuit serves as a substrate for a spiral antenna and the various electronic components for the operation of the system are arranged therein.

Le tout est alors placé dans la rainure 104 de la lunette 100 faisant office de logement.The whole is then placed in the groove 104 of the bezel 100 housing office.

Pour fermer le tout, un matériau polymère du type caoutchouc est surmoulé directement dans la rainure 104 formant un surmoulage 106 comme visible à la figure 3. Cette opération de surmoulage classique est destinée à recouvrir totalement le circuit de communication 102 ayant une forme de bague. Ce recouvrement total permet d'une part d'assurer une bonne étanchéité du système puisque le matériau polymère s'insère dans toute la rainure 104 empêchant ainsi les liquides de s'insérer.To close the whole, a rubber-like polymer material is overmolded directly into the groove 104 forming an overmolding 106 as visible in FIG. figure 3 . This conventional overmolding operation is intended to completely cover the communication circuit 102 having a ring shape. This total overlap makes it possible, on the one hand, to ensure a good seal of the system since the polymeric material is inserted throughout the groove 104 thus preventing the liquids from being inserted.

Un second avantage de cette réalisation est qu'elle permet d'améliorer la sécurité de cette lunette. En effet, les circuits de communication 102 pour cette lunette 100 peuvent utiliser des protocoles de communication sans contact de type NFC ou autre moyen de télécommunication sans fil. Ce système peut également être utilisé comme 'Tag' ou étiquette électronique pour la reconnaissance (ou le suivi) de produit. Ce protocole est principalement utilisé pour des fonctions de paiement ce qui implique que ces circuits contiennent des données sensibles. Par conséquent, il est nécessaire de les protéger. Etant donné que les protocoles de communication sans contact ont des portés extrêmement proches, la récupération de données sensibles se fait directement sur le circuit. Par conséquent, le fait de surmouler un polymère sur le circuit de communication 102 rend plus difficile la récupération d'informations car il devient nécessaire de dissoudre ce polymère avant d'avoir accès aux circuits de communication 102.A second advantage of this embodiment is that it improves the safety of this telescope. Indeed, the communication circuits 102 for this telescope 100 can use contactless communication protocols of the NFC type or other means of wireless telecommunications. This system can also be used as a 'tag' or electronic tag for product recognition (or tracking). This protocol is mainly used for payment functions which implies that these circuits contain data sensitive. Therefore, it is necessary to protect them. Since contactless communication protocols have extremely close ranges, the recovery of sensitive data is done directly on the circuit. Consequently, overmoulding a polymer on the communication circuit 102 makes it more difficult to recover information since it becomes necessary to dissolve this polymer before having access to the communication circuits 102.

Par ailleurs, la présence d'une opération de surmoulage permet d'avoir une lunette adaptative c'est-à-dire qu'il est envisageable de ne pas simplement avoir un circuit de communication. En effet, il est envisageable d'ajouter des indications de minuterie et/ou des autres indications techniques ou décoratives au niveau de la lunette.Moreover, the presence of an overmolding operation makes it possible to have an adaptive telescope, that is to say that it is conceivable not to simply have a communication circuit. Indeed, it is possible to add timer indications and / or other technical or decorative indications at the level of the telescope.

Selon un mode de réalisation avantageux, la lunette 100 selon l'invention comprend en outre un élément de minuterie 108. Cet élément de minuterie 108 se présente sous la forme d'une lamelle 109 dont les dimensions lui permettent d'être placée dans la rainure 104 de la lunette 100 comme visible à la figure 4. Dans le cas de la lunette 100, la lamelle 109 est de forme annulaire. Cette lamelle 109 se présente sous la forme d'une une bague réalisée dans un matériau plastique ou métallique ou organique comme du bois ou dans un matériau cristallin comme du saphir ou rubis ou céramique ou dans un matériau polymère incorporant un élément luminescent: phosphorescent ou fluorescent. Des indices de minuterie 110 sont alors réalisés en relief c'est à dire en surépaisseur. Cette bague 109 est alors astucieusement placée dans la rainure.According to an advantageous embodiment, the telescope 100 according to the invention further comprises a timer element 108. This timer element 108 is in the form of a strip 109 whose dimensions allow it to be placed in the groove 104 of the telescope 100 as visible in the figure 4 . In the case of the bezel 100, the lamella 109 is annular. This strip 109 is in the form of a ring made of a plastic or metal or organic material such as wood or in a crystalline material such as sapphire or ruby or ceramic or in a polymeric material incorporating a luminescent element: phosphorescent or fluorescent . Timer indices 110 are then made in relief, that is to say in overthickness. This ring 109 is then cleverly placed in the groove.

Pour cette installation de la bague de minuterie 108, deux alternatives sont possibles.For this installation of the timer ring 108, two alternatives are possible.

La première alternative consiste à dimensionner la rainure 104 de sorte que, lorsque l'élément de minuterie 108 est placé dans la rainure 104, les reliefs 110 affleurent du plan de la surface supérieure 100a de la lunette 100. Le tout est alors surmoulé par le polymère formant le surmoulage 106. L'affleurement des indices 110 permet, lors du surmoulage, d'avoir les reliefs visibles par l'utilisateur comme visible à la figure 5.The first alternative consists in dimensioning the groove 104 so that, when the timer element 108 is placed in the groove 104, the reliefs 110 are flush with the plane of the upper surface 100a of the telescope 100. The whole is then overmolded by the polymer forming overmolding 106. The outcropping of the indices 110 makes it possible, during overmoulding, to have the reliefs visible to the user as visible in the figure 5 .

Une seconde alternative consiste à surmouler une première couche ou surmoulage 106a de polymère sur le circuit de communication 102 avant de poser l'élément de minuterie 108. Une seconde opération de surmoulage est alors effectuée pour déposer une seconde couche de polymère ou surmoulage 106b pour maintenir l'élément de minuterie 108 dans la rainure 104 de la lunette 100. L'épaisseur de la première couche 106a de polymère déposée sera définie pour que les reliefs de l'élément de minuterie 108 affleurent du plan de la surface supérieure 100a de la lunette 100 comme visible à la figure 6.A second alternative is to overmold a first layer or overmold 106a of polymer on the communication circuit 102 before setting the timer element 108. A second overmoulding operation is then performed to deposit a second polymer layer or overmoulding 106b to maintain the timer element 108 in the groove 104 of the telescope 100. The thickness of the first deposited polymer layer 106a will be defined so that the reliefs of the timer element 108 are flush with the plane of the upper surface 100a of the telescope 100 as visible to the figure 6 .

Dans une variante des deux alternatives, l'élément de minuterie 108 est conçu pour comprendre une première lamelle 109 de minuterie réalisée dans un matériau transparent et une seconde lamelle 111, agencée sous la lamelle 109 de minuterie, qui sera une lamelle luminescente. Cela permet ainsi d'avoir l'aspect luminescent dans le cas où un mélange entre le matériau de la lamelle de minuterie 109 et le pigment luminescent n'est pas possible comme visible à la figure 7.In a variant of the two alternatives, the timer element 108 is designed to include a first timer strip 109 made of a transparent material and a second lamella 111, arranged under the timer lamella 109, which will be a luminescent lamella. This thus makes it possible to have the luminescent appearance in the case where a mixture between the material of the timer strip 109 and the luminescent pigment is not possible as visible in FIG. figure 7 .

Selon un autre mode de réalisation avantageux visible aux figures 8 et 9, la présence d'un marquage de minuterie sur la lunette 100. Pour cela, le surmoulage de la rainure avec un polymère est effectué afin de former des creusures 107 à sa surface. Ces creusures 107 ont, préférentiellement, des formes d'indices de minuterie. Ces creusures 107 ont pour but d'être remplies par une couche 112 d'un matériau tel qu'une encre. Cette encore peut être dépose par sprayage ou pas sérigraphie. Cette encre pourra être luminescente ou non selon les besoins. Les creusures peuvent être également remplis avec un métal du type métal amorphe.According to another advantageous embodiment visible to figures 8 and 9 , the presence of a timer marking on the bezel 100. For this, overmoulding of the groove with a polymer is performed to form recesses 107 at its surface. These recesses 107 have, preferably, forms of timer indices. These recesses 107 are intended to be filled by a layer 112 of a material such as an ink. This still can be deposited by spray or not screen printing. This ink may be luminescent or not as needed. The recesses can also be filled with a metal of amorphous metal type.

Dans un autre mode de réalisation visible à la figure 10, il est envisageable que la lunette soit intégrée. A cet effet, la carrure est réalisée de sorte que l'au moins une de ses faces puisse servir de lunette, cette carrure est alors appelée carrure lunette. Dans ce mode de réalisation, la face de la carrure faisant office de lunette est munie de la creusure dans laquelle le circuit de communication est placé.In another embodiment visible in the figure 10 it is conceivable that the telescope be integrated. For this purpose, the middle part is made so that the at least one of its faces can serve as a bezel, this middle case is then called middle bezel. In this embodiment, the face of the middle part serving as a telescope is provided with the recess in which the communication circuit is placed.

On comprendra que diverses modifications et/ou améliorations et/ou combinaisons évidentes pour l'homme du métier peuvent être apportées aux différents modes de réalisation de l'invention exposée ci-dessus sans sortir du cadre de l'invention définie par les revendications annexées.It will be understood that various modifications and / or improvements and / or combinations obvious to those skilled in the art can be made to the various embodiments of the invention set out above without departing from the scope of the invention defined by the appended claims.
