Description

DOMAINE TECHNIQUETECHNICAL AREA

La présente invention concerne une pièce d'horlogerie, plus particulièrement une montre-bracelet comportant une lunette interchangeable, c'est-à-dire une lunette qui puisse facilement être remplacée avec un positionnement précis et sans risques d'endommager les moyens d'assemblage.The present invention relates to a timepiece, more particularly a wristwatch having an interchangeable bezel, that is to say a bezel that can easily be replaced with a precise positioning and without risk of damaging the assembly means .

ARRIÈRE-PLAN TECHNOLOGIQUETECHNOLOGICAL BACKGROUND

On connaît déjà un certain nombre de dispositifs permettant, en particulier dans une montre-bracelet, de remplacer une lunette par une autre dans un but esthétique ou fonctionnel. Dans un but esthétique cela permet par exemple à moindre frais d'assortir la couleur de la partie la plus visible de la montre à celle de la tenue vestimentaire. Dans un but fonctionnel, le remplacement de la lunette permet par exemple de modifier les indications portées par ladite lunette, voire d'agir sur le mouvement pour avoir une montre multifonctions. Le brevet EP 0 603 353 décrit une montre dans laquelle le remplacement de la lunette permet de passer de l'affichage de l'heure courante à un mode « football » ou « tennis », la lunette choisie comportant alors des indications en rapport avec ces sports et des moyens permettant de commander le mécanisme horloger en fonction des règles desdits sports.A number of devices are already known which make it possible, in particular in a wristwatch, to replace one bezel with another for aesthetic or functional purposes. For aesthetic purposes it allows for example at lower cost to match the color of the most visible part of the watch to that of dress. For a functional purpose, the replacement of the telescope makes it possible for example to modify the indications carried by said telescope, or even to act on the movement to have a multifunctional watch. Patent EP 0 603 353 describes a watch in which the replacement of the telescope makes it possible to switch from the display of the current time to a "football" or "tennis" mode, the chosen telescope then including indications relating to these sports and means for controlling the watch mechanism according to the rules of said sports.

Selon l'art antérieur connu, la mise en place et le maintien d'une lunette amovible, ou inversement son remplacement, sont effectués selon des dispositifs pouvant être classés en deux grandes catégories, si on exclut des dispositifs peu commodes, nécessitant par exemple un vissage.According to the prior art known, the establishment and maintenance of a removable telescope, or conversely its replacement, are carried out according to devices that can be classified in two major categories, if we exclude inconvenient devices, requiring for example a screwing.

La fixation de la lunette amovible peut être effectuée par des moyens élastiques, comme cela est décrit dans le brevet GB 286 107. Ces moyens élastiques peuvent être formés par un anneau élastomère de forme appropriée comme décrit dans le modèle d'utilité japonais JP 4134178. Il peut également s'agir d'un dispositif d'encliquetage comme cela est décrit dans le brevet US 5 005 161. Dans tous ces assemblages élastiques il est difficile de trouver un bon compromis entre un dispositif suffisamment souple pour permettre à un usager de remplacer la lunette sans effort particulier et un dispositif suffisamment ferme pour éviter de la perdre accidentellement.Fixation of the removable bezel can be effected by elastic means, as described in GB 286 107. These elastic means can be formed by an elastomeric ring of appropriate shape as described in the Japanese utility model JP 4134178. It can also be a latching device as described in US Pat. No. 5,005,161. In all these elastic assemblies it is difficult to find a good compromise between a device that is sufficiently flexible to allow a user to replace the bezel without any special effort and a device firm enough to avoid losing it accidentally.

Pour pallier l'inconvénient sus-indiqué, il est proposé dans un certain nombre de constructions d'assujettir la lunette à la carrure au moyen d'un dispositif dit « à baïonnette ». Le dispositif consiste à prévoir dans la lunette et dans la partie supérieure de la carrure ou du fond-carrure des moyens complémentaires mâle et femelle venant s'engager l'un dans l'autre lorsqu'on imprime un mouvement de rotation à la lunette. Il est également généralement prévu un système de sécurité pour le verrouillage/déverrouillage de la lunette. Une construction de ce type est décrite dans le brevet US 5 490 123, le système de sécurité étant constitué par un bouton poussoir situé au niveau d'une corne de la boîte. Dans la demande de brevet européen EP 1 249 741, le dispositif à baïonnette comporte un verrouillage constitué par des puits ménagés dans la carrure et logeant un ressort permettant de pousser une bille dans des évidements pratiqués dans la face interne de la lunette. Ces constructions ont encore l'inconvénient d'être relativement complexes et de présenter une certaine fragilité, notamment lorsque le dispositif à baïonnette est mis en place avec un mouvement de rotation de la lunette trop appuyé susceptible d'endommager les éléments de l'assemblage.To overcome the disadvantage mentioned above, it is proposed in a number of constructions to secure the bezel to the middle part by means of a device called "bayonet". The device consists in providing in the bezel and in the upper part of the middle part or middle part of the complementary means male and female engaging one into the other when printing a rotational movement to the telescope. It is also generally provided a security system for locking / unlocking the telescope. A construction of this type is described in US Patent 5,490,123, the security system being constituted by a push button located at a horn of the box. In the European patent application EP 1 249 741, the bayonet device comprises a locking constituted by wells in the middle part and housing a spring for pushing a ball in recesses made in the inner face of the bezel. These constructions have the further disadvantage of being relatively complex and presenting a certain fragility, especially when the bayonet device is set up with a rotational movement of the telescope too supported could damage the elements of the assembly.

RÉSUMÉ DE L'INVENTIONSUMMARY OF THE INVENTION

La présente invention vise donc à pallier les inconvénients de l'art antérieur précité en permettant de remplacer facilement une lunette par une autre lunette, par un dispositif à baïonnette, avec un positionnement précis et sans risquer d'endommager les moyens d'assemblage.The present invention therefore aims to overcome the disadvantages of the aforementioned prior art by allowing to easily replace a bezel by another bezel, by a bayonet device, with a precise positioning and without risking damaging the assembly means.

A cet effet, l'invention a pour objet une pièce d'horlogerie, qui sera illustrée par la suite (par une montre-bracelet, à lunette interchangeable et verrouillable au moyen d'un dispositif à baïonnette prévu sur la partie supérieure de la carrure d'une boîte fermée par un fond et contenant un mouvement horloger pour un affichage analogique ou digital d'informations horaires ou non horaires. La pièce d'horlogerie est caractérisée en ce que la portée de la carrure est pourvue d'une rainure circulaire et d'au moins deux puits débouchant partiellement dans ladite rainure. La lunette comporte au moins deux pieds positionnés sur sa face interne pour venir s'engager dans les puits, lesdits pieds comportant chacun une encoche ouverte radialement au-dessus de l'émergence des puits. Ces encoches constituent la partie « mâle » du dispositif à baïonnette. La partie « femelle » est constituée par un anneau de verrouillage/déverouillage placé dans la rainure, pourvu d'un organe extérieur de manoeuvre en rotation dont un bord a une épaisseur sensiblement égale à l'ouverture des encoches dans les pieds, et comporte des évidements pour le passage des pieds. L'autre bord de l'anneau comporte une gorge annulaire en regard d'une gorge formée dans un manchon de la carrure, les deux gorges permettant de loger un ressort de clipsable de l'anneau dans la rainure, tout en permettant de laisser ledit anneau mobile en rotation.For this purpose, the subject of the invention is a timepiece, which will subsequently be illustrated (by a wristwatch, with interchangeable bezel and lockable by means of a bayonet device provided on the upper part of the middle part a box closed by a bottom and containing a watch movement for an analogue or digital display of hourly or non-hourly information The timepiece is characterized in that the scope of the middle part is provided with a circular groove and at least two wells partially opening into said groove The bezel comprises at least two feet positioned on its internal face to engage in the wells, said feet each having a notch open radially above the emergence of the wells These notches constitute the "male" part of the bayonet device The "female" part is constituted by a locking / unlocking ring placed in the groove, provided with an org an outer rotating maneuver whose one edge has a thickness substantially equal to the opening of the notches in the feet, and has recesses for the passage of the feet. The other edge of the ring has an annular groove facing a groove formed in a sleeve of the middle part, the two grooves for accommodating a snap-fastening spring of the ring in the groove, while allowing to leave said rotating ring.

Ainsi pour enlever une lunette il suffit de faire tourner l'anneau avec l'organe de manoeuvre jusqu'à une position où les évidements dans le bord de l'anneau se trouvent exactement positionnés au-dessus des puits et libèrent le passage des pieds de la lunette. Pour adapter une nouvelle lunette, il suffit d'effectuer l'opération inverse, puis de faire tourner l'anneau de verrouillage pour que le bord s'engage dans les encoches des pieds.Thus to remove a bezel simply rotate the ring with the actuator to a position where the recesses in the edge of the ring are exactly positioned above the wells and release the passage of the feet of the glasses. To adapt a new telescope, simply perform the opposite operation, then rotate the locking ring so that the edge engages in the notches of the feet.

Pour éviter le déplacement accidentel de l'organe de manoeuvre, le fond de la rainure formée dans la portée de la carrure est pourvu d'un ressort à cliquet qui coopère avec un bossage formé à la base de l'anneau de verrouillage.To avoid accidental movement of the operating member, the bottom of the groove formed in the scope of the caseband is provided with a ratchet spring which cooperates with a boss formed at the base of the locking ring.

Le nombre de pieds, respectivement de puits, est au minimum de deux. Dans un mode de réalisation préféré ils sont au nombre de quatre en étant disposés en rectangle, pour ne laisser que deux choix possibles au positionnement de la lunette, et les pieds peuvent soit venir de matière avec la lunette, soit être formés par des cavaliers traversant son épaisseur.The number of feet or wells is at least two. In a preferred embodiment there are four in being arranged in a rectangle, leaving only two possible choices to the positioning of the bezel, and the feet can either come from material with the bezel, or be formed by riders crossing its thickness.

DESCRIPTION DÉTAILLÉE DE L'INVENTIONDETAILED DESCRIPTION OF THE INVENTION

L'invention est décrite ci-après plus en détails en prenant à titre d'exemple une montre-bracelet chronographe représentée en perspective à la figure 1 et en vue de dessus à la figure 2, essentiellement pour mieux préciser les coupes des figures suivantes.The invention is described below in more detail by taking as an example a chronograph wristwatch shown in perspective in Figure 1 and a top view in Figure 2, essentially to better specify the sections of the following figures.

Comme on le voit la montre représentée comprend une boîte 10 formée d'une carrure 12 fermée par un fond 13 et par une glace 8 pour loger un mouvement de chronographe 7 (représenté à la figure 3) ayant de façon connue une couronne 19a et deux poussoirs 19b. La glace 8 est entourée par une lunette 1, verrouillée par un dispositif à baïonnette sur la portée supérieure 11 de la carrure 12 lorsque l'organe extérieur 21 est positionné à 9 heures et pouvant être déverrouillée lorsqu'on imprime un mouvement de rotation audit organe pour l'amener par exemple à la position 10 heures, comme représenté en pointillés par la référence 21 a.As can be seen, the watch shown comprises a box 10 formed of a middle part 12 closed by a bottom 13 and an ice-cream 8 for accommodating a chronograph movement 7 (shown in FIG. 3) having in known manner a crown 19a and two pushers 19b. The glass 8 is surrounded by a bezel 1, locked by a bayonet device on the upper bearing 11 of the middle part 12 when the outer member 21 is positioned at 9 o'clock and can be unlocked when a rotational movement is imparted to said member to bring it for example to the 10 o'clock position, as shown in dotted lines by the reference 21 a.

La construction du dispositif à baïonnette est maintenant expliquée en se référant d'abord à la figure 3 qui est une représentation en perspective éclatée de la montre représentée à la figure 1. Le dispositif à baïonnette comprend une lunette 1, une boîte 10 et un anneau de verrouillage 20, représentés séparément en vue de dessus aux figures 4, 5 et 6.The construction of the bayonet device is now explained by first referring to FIG. 3 which is an exploded perspective representation of the watch shown in FIG. 1. The bayonet device comprises a bezel 1, a box 10 and a ring 20, shown separately in plan view in Figures 4, 5 and 6.

La boîte 10 comprend une carrure 12, dans laquelle est montée un mouvement horloger 7 et un cadran 27, fermée par un fond 13 avec interposition d'un point d'étanchéité 3. La portée supérieure 11 de la carrure 12 comporte une rainure circulaire 14, dont le bord orienté vers le centre du cadran 27 est prolongé par un manchon 17. La portée 11 comporte également quatre puits verticaux 15 qui débouchent partiellement dans la rainure 14, c'est-à-dire en ayant une ouverture en intersection avec un bord de la rainure 14, qui est le bord extérieur dans cet exemple. Le manchon 17 de la carrure 12 comporte une gorge annulaire 16 située au-dessus de la portée 11. On voit également que la portée 11 comporte un évidemment 18 dans un secteur angulaire situé autour de 9 heures pour permettre le passage de l'organe de manoeuvre 21. Sur cette carrure vient évidemment s'ajuster en affleurement du manchon 17, la glace 8 et le joint d'étanchéité 9.The box 10 comprises a middle part 12, in which is mounted a watch movement 7 and a dial 27, closed by a bottom 13 with the interposition of a sealing point 3. The upper bearing 11 of the middle part 12 comprises a circular groove 14 , whose edge oriented towards the center of the dial 27 is extended by a sleeve 17. The bearing 11 also comprises four vertical wells 15 which open partially into the groove 14, that is to say having an opening in intersection with a edge of the groove 14, which is the outer edge in this example. The sleeve 17 of the middle part 12 has an annular groove 16 situated above the span 11. It can also be seen that the bearing 11 includes a recess 18 in an angular sector situated around 9 o'clock to allow the passage of the maneuver 21. Of course, this caseband fits flush with the sleeve 17, the window 8 and the seal 9.

La lunette interchangeable 1, représentée aux figures 3, 3 bis, 4 et 4 bis est pourvue de pieds 2 dont la section permet un engagement doux dans les puits 15 et qui sont donc répartis à la base de la lunette selon les mêmes coordonnées polaires que les puits 15. Les pieds 2 présentent des encoches 4 situées au-dessus de la portée 11 lorsque les pieds 2 sont engagés dans les puits 15, dont la découpe correspond au moins à l'intersection des puits 15 et de la rainure 14 et dont l'ouverture correspond à l'épaisseur de l'anneau de verrouillage 20, comme cela sera expliqué plus loin.The interchangeable bezel 1, represented in FIGS. 3, 3a, 4 and 4a, is provided with feet 2 whose section allows a gentle engagement in the wells 15 and which are therefore distributed at the base of the telescope according to the same polar coordinates as the wells 15. The feet 2 have notches 4 located above the reach 11 when the feet 2 are engaged in the wells 15, the cutting corresponds at least to the intersection of the wells 15 and the groove 14 and whose opening corresponds to the thickness of the locking ring 20, as will be explained later.

En se référant plus particulièrement aux figures 3, 4 et 4 bis on voit que la lunette 1 est traversée par quatre perçages 5 destinés à recevoir deux cavaliers 6 dont les parties recourbées forment les pieds 2. Ces cavaliers 6 peuvent à la fois faciliter la construction de la lunette, avoir un effet décoratif, assurer une protection de la glace 8 en cas de choc et procurer un positionnement quasi-univoque de la lunette 1 si les pieds 2 sont disposés dans les angles d'un rectangle.
La figure 3 bis représente une construction simplifiée dans laquelle la lunette 1 ne comporte que deux pieds 2 venant de matière avec le corps de la lunette 1, c'est-à-dire sans cavalier.Referring more particularly to Figures 3, 4 and 4a we see that the bezel 1 is traversed by four holes 5 for receiving two riders 6 whose curved parts form the feet 2. These riders 6 can both facilitate the construction of the bezel, have a decorative effect, provide protection of the ice 8 in the event of shock and provide an almost unambiguous positioning of the bezel 1 if the feet 2 are arranged in the corners of a rectangle.
Figure 3a shows a simplified construction in which the bezel 1 has only two feet 2 of material with the body of the bezel 1, that is to say without jumper.

En se référant maintenant également aux figures 5, 9 à 12 on décrit ci-après la partie « mâle » du dispositif de verrouillage à baïonnette. Cette partie « mâle » est constituée par un anneau 20 relié à l'organe de manoeuvre 21 par une bande de liaison 28 et dont la base vient se loger dans la rainure 14. Le bord extérieur 23 de l'anneau 20 a une épaisseur correspondant à l'ouverture des encoches 4 dans les pieds 2 et un diamètre tel qu'il vienne affleurer le fond desdites encoches 4 lorsque les pieds 2 sont mis en place. Pour permettre le passage de la section pleine des pieds 2, le bord externe 23 comporte des évidements 24 dont le contour correspond à l'intersection des puits 15 et de la rainure 14. Le bord interne 25 de l'anneau comporte un manchon 22 venant en appui à frottement gras contre un manchon 17 de la carrure. Le manchon 22 comporte une gorge annulaire 26 en regard de la gorge 16 du manchon 17 de la carrure. Les deux gorges 16, 26 permettent de mettre en place un clips, tel que le ressort 30 ouvert à contour polygonal pour solidariser l'anneau de verrouillage 20 à la boîte 10, tout en permettant de le manoeuvrer autour de la position 9 heures entre une position verrouillée 21 et une position déverrouillée 21 a, comme représentée à la figure 1. Dans un but esthétique, mais aussi pour éviter que des salissures pénètrent par l'évidemment 18, la jonction 28 est prolongée, de part et d'autre de l'organe de manoeuvre 21, par des extensions 28a qui affleurent la carrure 12 et qui enveloppent deux évidements 24Referring now also to FIGS. 5, 9 to 12, the "male" part of the bayonet locking device is described below. This "male" portion is constituted by a ring 20 connected to the operating member 21 by a connecting strip 28 and whose base is housed in the groove 14. The outer edge 23 of the ring 20 has a corresponding thickness at the opening of the notches 4 in the feet 2 and a diameter such that it comes flush with the bottom of said notches 4 when the feet 2 are put in place. To allow the passage of the full section of the feet 2, the outer edge 23 has recesses 24 whose contour corresponds to the intersection of the wells 15 and the groove 14. The inner edge 25 of the ring comprises a sleeve 22 from in support against fat friction against a sleeve 17 of the middle part. The sleeve 22 has an annular groove 26 opposite the groove 16 of the sleeve 17 of the middle part. The two grooves 16, 26 make it possible to put in place a clip, such as the open spring 30 with a polygonal contour for securing the locking ring 20 to the box 10, while allowing it to be maneuvered around the 9 o'clock position between a locked position 21 and an unlocked position 21a, as shown in Figure 1. For aesthetic purpose, but also to prevent dirt from entering the recess 18, the junction 28 is extended, on both sides of the maneuvering member 21, by extensions 28a which are flush with the middle part 12 and which envelop two recesses 24

Pour maintenir l'anneau dans l'une ou l'autre des positions verrouillée/déverrouillée, le montage à frottement gras sur le manchon 17 de la carrure peut être suffisant. Il est toutefois préférable de prévoir, comme cela est visible sur la figure 10, un bossage 29 à la base de la carrure destiné à coopérer avec un ressort à cliquet 31 venant se positionner en fond de la rainure 14, comme représenté à la figure 3 et dans les coupes des figures 7 et 8. Ce ressort à cliquet pourrait évidemment, sans sortir du cadre de l'invention être positionné à d'autres endroits où il existe des parois de la carrure 12 et de l'anneau de verrouillage 20 en regard.To keep the ring in one of the locked / unlocked positions, the friction fit on the sleeve 17 of the caseband may be sufficient. However, it is preferable to provide, as can be seen in FIG. 10, a boss 29 at the base of the middle part intended to cooperate with a ratchet spring 31 which is positioned at the bottom of the groove 14, as represented in FIG. and in the sections of FIGS. 7 and 8. This ratchet spring could obviously, without departing from the scope of the invention be positioned in other places where there are walls of the middle part 12 and the locking ring 20 opposite.

La description précédente a été faite en référence à un mode de réalisation préféré, mais d'autres modifications peuvent être apportées par l'homme du métier sans sortir du cadre de la présente invention. Il est par exemple possible de concevoir l'anneau de verrouillage 20 avec une section « en image de miroir » et de disposer l'organe de manoeuvre 21 au niveau du fond de la boîte 10 en donnant à l'extension 28 une forme coudée pour traverser la carrure 12 à travers une fente pratiquée dans le fond de la rainure 14, perpendiculairement au fond.The foregoing description has been made with reference to a preferred embodiment, but other modifications may be made by those skilled in the art without departing from the scope of the present invention. For example, it is possible to design the locking ring 20 with a "mirror image" section and to arrange the operating member 21 at the bottom of the box 10 by giving the extension 28 a bent shape for cross the middle part 12 through a slot in the bottom of the groove 14, perpendicular to the bottom.
