Description
MONTRE-BRACELET COMPORTANT UNE LUNETTE AMOVIBLE BRACELET WATCH HAVING A REMOVABLE LENS
La présente invention se rapporte au domaine de l'horlogerie et plus particulièrement à une lunette décorative et/ou fonctionnelle amovible d'une montre-bracelet et à une montre-bracelet munie d'une telle lunette. The present invention relates to the field of watchmaking and more particularly to a removable decorative and / or functional bezel of a wristwatch and a wristwatch provided with such a bezel.
Il existe déjà dans l'état de la technique un certain nombre de dispositifs permettant de remplacer la lunette d'une montre-bracelet par une autre dans un but esthétique ou fonctionnel. GB286107 et US5005161 divulguent par exemple des systèmes de fixation de la lunette amovible par des moyens élastiques. Dans ce genre de dispositifs, la bonne tenue de la lunette dépend des propriétés élastiques des moyens utilisés. Aussi, il est difficile de trouver un bon compromis afin de permettre à un usager de remplacer la lunette amovible sans effort particulier tout en assurant une fixation fiable de celle-ci pour éviter de la perdre accidentellement. There are already in the state of the art a number of devices for replacing the bezel of a wristwatch by another for aesthetic or functional purpose. GB286107 and US5005161 disclose, for example, systems for fixing the removable telescope by elastic means. In this type of device, the good behavior of the telescope depends on the elastic properties of the means used. Also, it is difficult to find a good compromise to allow a user to replace the removable bezel without special effort while ensuring a reliable attachment thereof to avoid losing it accidentally.
Afin de surmonter cet inconvénient, plusieurs dispositifs dit "à baïonnette" ont été développés. EP1249741 décrit par exemple une boîte de montre qui est munie d'une lunette décorative amovible, dans laquelle cette lunette décorative est pourvue sur la boîte par une pluralité de moyens de fixation de type baïonnette associés à des moyens de blocage. Ces derniers comportent des moyens élastiques conçus pour exercer une pression tendant à écarter cette lunette de ladite boîte, ces moyens étant disposés pour exercer une pression sensiblement uniforme sur l'ensemble du pourtour de ladite lunette. Des éléments de positionnement entre la lunette et la boîte sont par ailleurs agencés pour s'opposer au déplacement de ladite lunette tant qu'une force déterminée, de direction opposée à celle provoquant l'engagement des moyens de fixation à baïonnette n'a pas été appliquée à cette lunette. D'autres exemples de dispositifs à baïonnette adaptés à une lunette amovible d'une montre bracelet sont divulgués par exemple dans les publications EP0621518 et EP1662342. In order to overcome this disadvantage, several "bayonet" devices have been developed. EP1249741 describes for example a watch case which is provided with a removable decorative bezel, in which this decorative bezel is provided on the box by a plurality of bayonet type fixing means associated with locking means. The latter comprise elastic means designed to exert a pressure tending to separate this bezel from said box, these means being arranged to exert a substantially uniform pressure on the entire periphery of said bezel. Positioning elements between the bezel and the box are also arranged to oppose the movement of said bezel as a determined force, of direction opposite to that causing the engagement of the bayonet fixing means has not been applied to this telescope. Other examples of bayonet devices adapted to a removable bezel of a wristwatch are disclosed for example in the publications EP0621518 and EP1662342.
Le but de la présente invention est de proposer une lunette amovible pour montre-bracelet comportant un autre type de dispositif permettant d'une part, une fixation fiable de la lunette à la carrure de la boîte de montre et, d'autre part, une manipulation aisée pour le changement de la lunette. Conformément à l'invention, ce but est atteint grâce à une lunette amovible destinée à être agencée sur la portée d'une boîte de montre dans une position angulaire initiale puis actionnée en rotation jusqu'à ce qu'elle se trouve dans une position angulaire verrouillée dans laquelle la lunette amovible est bloquée en rotation. La lunette amovible comporte des premiers moyens de retenue agencés, lorsque la lunette amovible est montée sur la boîte de montre, pour coopérer avec des seconds moyens de retenue disposés sur la boîte de montre pour fixer la lunette amovible sur la boîte de montre dans ladite position angulaire verrouillée. Ladite lunette amovible comporte en outre sur sa périphérie au moins un poussoir actionnable radialement, le ou les poussoirs comportant chacun un élément de verrouillage/déverrouillage de la rotation de la lunette amovible. Cet élément de verrouillage/déverrouillage coopère, lorsque la lunette amovible est montée sur la boîte de montre, avec la portée de la boîte de montre de manière à ce qu'une pression sur le ou les poussoirs déverrouille la lunette amovible en rotation. The purpose of the present invention is to provide a removable wristwatch bezel comprising another type of device allowing on the one hand, a reliable attachment of the bezel to the middle of the watch case and, on the other hand, a easy handling for the change of the telescope. According to the invention, this object is achieved by means of a removable bezel intended to be arranged on the range of a watch case in an initial angular position and then actuated in rotation until it is in an angular position. locked in which the removable bezel is locked in rotation. The removable bezel has first retaining means arranged, when the removable bezel is mounted on the watch case, to cooperate with second retaining means arranged on the watch case to fix the removable bezel on the watch case in said position. angular locked. Said removable bezel further comprises on its periphery at least one radially actuable pusher, or the pushers each having a locking / unlocking element of the rotation of the removable telescope. This locking / unlocking element cooperates, when the removable bezel is mounted on the watch case, with the scope of the watch case so that a pressure on the pushbutton or unlocking unlocks the rotating bezel.
L'invention porte également sur une boîte de montre destinée à recevoir la lunette amovible. La boîte de montre possède deux gorges diamétralement opposées et s'entendant chacune en arc de cercle, de préférence sur 90°, autour de l'axe centrale de la boîte de montre. Les extrémités de chaque gorge possède une partie coudée de manière à ce que chaque élément de verrouillage/ déverrouillage de la lunette amovible puisse être dégagé de la gorge respective sous l'action des moyens de rappel des poussoirs afin de verrouiller la rotation de la lunette amovible dans l'une ou l'autre dédites positions angulaires verrouillées. The invention also relates to a watch case for receiving the removable bezel. The watch case has two diametrically opposed grooves each extending in an arc of a circle, preferably 90 °, around the central axis of the watch case. The ends of each groove have an angled portion so that each locking / unlocking element of the removable bezel can be disengaged from the respective groove under the action of the pusher return means to lock the rotation of the removable bezel in one or the other dedicated locked angular positions.

Selon la forme d'exécution préférentielle de l'invention, la lunette amovible 1 comporte, comme illustré à la Figure 2, une lunette décorative principale 1a possédant sur son côté inférieur deux logements 11 , 11' (Figure 3) qui sont agencés à 180° l'un par rapport à l'autre. Chaque logement 11 , 11' est destiné à recevoir un poussoir 4, 4' ainsi que des moyens de rappel sous la forme de deux ressorts de compression 5 qui sont disposés dans deux saignées 4a, pratiquées sur le poussoir (Figures 2 et 5). Les saignées 4a sont orientées de manière à ce qu'une extrémité de chaque ressort 5 soit en appui contre le poussoir 4 et que l'autre extrémité soit en appui contre le fond du logement. La lunette amovible 1 comporte en outre une embase annulaire 12 (Figure 2) fixée sur le côté inférieur de la lunette principale 1a afin d'encapsuler les ressorts de compression 5 et partiellement les poussoirs 4, 4' dans leur logement respectif 11 , 11'. According to the preferred embodiment of the invention, the removable bezel 1 comprises, as shown in Figure 2, a main decorative bezel 1a having on its lower side two housings 11, 11 '(Figure 3) which are arranged at 180 ° with respect to each other. Each housing 11, 11 'is intended to receive a pusher 4, 4' and return means in the form of two compression springs 5 which are arranged in two grooves 4a, made on the pusher (Figures 2 and 5). The grooves 4a are oriented so that one end of each spring 5 bears against the pusher 4 and the other end bears against the bottom of the housing. The removable bezel 1 further comprises an annular base 12 (Figure 2) attached to the lower side of the main bezel 1a to encapsulate the compression springs 5 and partially the pushers 4, 4 'in their respective housing 11, 11' .
Au vu notamment des Figures 2 et 6, chaque poussoir 4, 4' comporte un élément de verrouillage/déverrouillage de la lunette amovible 1 sous la forme d'une vis 6, 6' laquelle est montée perpendiculairement au déplacement radial des poussoirs 4, 4' lorsqu'ils sont actionnés. Ces vis 6, 6' sont agencées pour coopérer avec la portée 2 d'une boîte de montre 3 telle qu'illustrée par la Figure 8 afin que cette lunette amovible 1 puisse être verrouillée en rotation dans une première et une seconde position angulaire verrouillée qui sont séparées préférablement de 90°. In particular seen in Figures 2 and 6, each pusher 4, 4 'comprises a locking / unlocking element of the removable bezel 1 in the form of a screw 6, 6' which is mounted perpendicular to the radial displacement of pushers 4, 4 'when actuated. These screws 6, 6 'are arranged to cooperate with the scope 2 of a watch case 3 as illustrated by Figure 8 so that the removable bezel 1 can be locked in rotation in a first and a second locked angular position which are preferably separated by 90 °.
A cet effet, en référence en particulier à la Figure 8, la portée 2 de la boîte de montre 3 destinée à recevoir la lunette amovible 1 selon l'invention possède deux gorges 9, 9' diamétralement opposées qui s'étendent chacune en arc de cercle, de préférence sur 90°, autour de l'axe central de la boîte de montre. Les extrémités de chaque gorge 9, 9' possèdent une partie coudée 10 qui se trouvent respectivement à 12h, 3h, 6h et 9h afin d'y recevoir la vis 6, 6' de chaque poussoir 4, 4' de la lunette amovible 1 sous l'action des ressort de compression 5. Les vis 6, 6' sont alors dégagées de leur gorge respective 9, 9' lorsqu'elles atteignent l'une ou l'autre des deux positions angulaires verrouillées afin de bloquer en rotation la lunette amovible 1. For this purpose, with particular reference to Figure 8, the scope 2 of the watch case 3 for receiving the removable bezel 1 according to the invention has two grooves 9, 9 'diametrically opposed, each extending in an arc of circle, preferably 90 °, around the central axis of the watch case. The ends of each groove 9, 9 'have a bent portion 10 which are respectively at 12h, 3h, 6h and 9h in order to receive the screw 6, 6' of each pusher 4, 4 'of the removable bezel 1 under the action of the compression springs 5. The screws 6, 6 'are then disengaged from their respective grooves 9, 9' when they reach one or the other of the two locked angular positions in order to lock in rotation the removable bezel 1.
En référence à aux Figures 3 et 4 et 7, la lunette amovible 1 selon l'invention comporte en outre des premiers moyens de retenue 7, 7' qui sont agencés pour coopérer avec des seconds moyens de retenue 8, 8' disposés sur la boîte de montre 3 (Figures 2, 6, 7 et 8) lorsque la lunette amovible 1 est fixée sur ladite boîte 3 et se trouve dans l'une de ses deux positions angulaires verrouillées afin que ladite lunette 1 soit solidaire de la boîte de montre 3. Les premiers moyens de retenue 7, 7' de la lunette amovible 1 sont alors dégagés des seconds moyens de retenue 8, 8' de la boîte de montre 3 lorsque la lunette amovible 1 se trouve dans l'autre de ses deux positions angulaires verrouillées pour que la lunette amovible 1 puisse être désolidarisée de la boîte de montre 3. Referring to Figures 3 and 4 and 7, the removable bezel 1 according to the invention further comprises first retaining means 7, 7 'which are arranged to cooperate with second retaining means 8, 8' arranged on the box 3 (Figures 2, 6, 7 and 8) when the removable bezel 1 is fixed on said box 3 and is in one of its two locked angular positions so that said bezel 1 is integral with the watch case 3 The first retaining means 7, 7 'of the removable bezel 1 are then disengaged from the second retaining means 8, 8' of the watch case 3 when the removable bezel 1 is in the other of its two locked angular positions. so that the removable bezel 1 can be detached from the watch case 3.
Plus particulièrement, les premiers moyens de retenue de la lunette amovible 1 sont sous la forme d'une projection 7, 7' (Figure 3) qui s'étend sur la circonférence interne de ladite lunette amovible 1 de part et d'autre du chaque poussoir 4, 4' de préférence entre 20° et 45°. Les seconds moyens de retenue de la boîte de montre 3 sont sous la forme de deux rebords 8', 8' diamétralement opposés et qui s'étendent chacun sur au moins 30° et de préférence sur environ 45° le long d'une paroi latérale circulaire 13, laquelle est agencée sur la circonférence interne de la portée 2 de la boîte de montre 3. More particularly, the first retaining means of the removable bezel 1 are in the form of a projection 7, 7 '(Figure 3) which extends on the inner circumference of said removable bezel 1 on either side of each pusher 4, 4 'preferably between 20 ° and 45 °. The second retaining means of the watch case 3 are in the form of two flanges 8 ', 8' diametrically opposed and each extending at least 30 ° and preferably about 45 ° along a circular side wall 13, which is arranged on the inner circumference of the scope 2 of the watch case 3.
La portée 2 de la boîte de montre 3 comporte en outre deux logements cylindriques 17 (Figure 2) diamétralement opposés situés chacun entre les deux gorges 9, 9' en arc de cercle, et dans lesquels sont ajustés une douille 14 contenant une bille 15 qui est retenue par un rebord 14a de la douille 14 (Figure 7) et pressée contre ce rebord 14a par un ressort 16. La répartition des billes 15 sur la portée 2 de la boîte de montre permet d'exercer une pression tendant à plaquer les projections 7, 7' de la lunette amovible 1 contre les rebords 8, 8' de la paroi latérale circulaire 13 de la boîte de montre 3. Par ailleurs, les billes 15 servent aussi d'éléments de roulement lors de la rotation de la lunette amovible 1 , rendant la mise en place et l'enlèvement de la lunette plus agréable. The scope 2 of the watch case 3 furthermore comprises two diametrically opposed cylindrical housings 17 (FIG. 2) situated each between the two grooves 9, 9 'in an arc of a circle, and in which are fitted a bush 14 containing a ball 15 which is retained by a flange 14a of the sleeve 14 (Figure 7) and pressed against the rim 14a by a spring 16. The distribution of the balls 15 on the scope 2 of the watch case allows to exert a pressure tending to press the projections 7, 7 'of the removable bezel 1 against the flanges 8, 8' of the circular side wall 13 of the watch case 3. Furthermore, the balls 15 also serve as rolling elements during the rotation of the removable bezel 1, making the setting up and removal of the bezel more pleasant.
Au vu de ce qui précède, la fixation de la lunette amovible 1 sur la boîte de montre 3, selon cette forme d'exécution, est effectuée de la façon suivante: In view of the above, the attachment of the removable bezel 1 on the watch case 3, according to this embodiment, is performed as follows:
En premier lieu, la lunette amovible 1 est ajustée sur la portée 2 de manière à ce que la tête de la vis 6, 6' de chaque poussoir 4, 4' se trouve dans la partie coudée des deux gorges 9, 9 respectivement à 12h et 6h. Les poussoirs 4, 4' diamétralement opposés sont ensuite actionnés simultanément afin que la tête de la vis 6, 6' de chaque poussoir s'engage dans leur gorge 9, 9' respective. A cet instant, une pression axiale est appliquée à la lunette amovible 1 tout en la tournant de 90° dans le sens des aiguilles d'une montre afin d'aligner les projections 7, 7' de la lunette amovible 1 sous les rebords 8, 8' de la paroi annulaire 13 de la boîte de montre 3. Lorsque la rotation de 90° de la lunette 1 est terminée, la tête de la vis 6,6' de chaque poussoir 4, 4' est dégagée de la gorge respective 9, 9' sous l'action des ressors de compression 5 afin de verrouiller la lunette amovible 1 en rotation (Figures 5 et 6). A cet instant les deux poussoirs 4, 4' de la lunette amovible 1 se trouve à 3h, respectivement 6h. Lorsque la pression axiale n'est plus appliquée à la lunette 1 , les billes 15 sur la portée 2 de la boîte de montre 3 permet d'exercer une pression tendant à plaquer les projections 7, 7' de la lunette amovible 1 contre les rebords 8, 8' de la paroi latérale circulaire 13 de la boîte de montre. La lunette amovible 1 se retrouve totalement sécurisée puisqu'elle est verrouillée axialement et en rotation. First, the removable bezel 1 is adjusted to the bearing surface 2 so that the head of the screw 6, 6 'of each pusher 4, 4' is in the bent portion of the two grooves 9, 9 respectively at 12 o'clock and 6h. The pushers 4, 4 'diametrically opposed are then actuated simultaneously so that the head of the screw 6, 6' of each pusher engages in their groove 9, 9 'respectively. At this moment, an axial pressure is applied to the detachable telescope 1 while turning it 90 ° clockwise in order to align the projections 7, 7 'of the removable telescope 1 under the flanges 8, 8 'of the annular wall 13 of the watch case 3. When the 90 ° rotation of the bezel 1 is completed, the head of the screw 6,6' of each pusher 4, 4 'is disengaged from the respective groove 9 9 'under the action of compression springs 5 to lock the removable bezel 1 in rotation (Figures 5 and 6). At this moment the two pushers 4, 4 'of the removable bezel 1 is at 3 o'clock, respectively 6 o'clock. When the axial pressure is no longer applied to the bezel 1, the balls 15 on the scope 2 of the watch case 3 can exert a pressure tending to press the projections 7, 7 'of the removable bezel 1 against the edges 8, 8 'of the circular side wall 13 of the watch box. The removable bezel 1 is completely secure since it is locked axially and rotationally.
La description susvisée porte uniquement sur une forme d'exécution préférentielle, mais certaines modifications peuvent être apportées par l'homme du métier sans sortir du cadre de la présente invention telle que définie par les revendications. Il est par exemple possible de concevoir une lunette amovible qui comporte uniquement un poussoir dont l'actionnement permet de déverrouiller la lunette en rotation. Par ailleurs, les gorges en arc de cercle peuvent être décalées de 90° afin que la fixation de la lunette amovible sur la boîte de montre se fasse dans le sens contraires des aiguilles d'une montre. The above description relates only to a preferred embodiment, but some modifications may be made by those skilled in the art without departing from the scope of the present invention as defined by the claims. It is for example possible to design a removable bezel which comprises only a pushbutton whose actuation can unlock the rotating bezel.
