Abstract

The invention concerns a watch case equipped with a decorative bezel, wherein said decorative bezel (7, 17) is maintained on the case by a plurality of bayonet-type fixing means (6, 16, 8, 18) associated with locking means (4, 10, 14, 20) which include elastic means (5, 15) designed to exert pressure tending to space part said bezel (7, 17) from said case (1, 11), and arranged such that the pressures which they exert are distributed substantially uniformly over the whole periphery of said bezel (7, 17) and positioning elements (10, 20) between said bezel (7, 17) and said case (1, 11) designed to counter the displacement of said bezel positioned on the case so long as a specific force, of opposite direction to that engaging the bayonet fixing means (1, 16, 8, 18) has not been applied to said bezel (7, 17).

Description

BOITE DE MONTRE MUNIE D'UNE LUNETTE DECORATIVE AMOVIBLE WATCHBOX WITH REMOVABLE DECORATIVE GLASS
La présente invention se rapporte à une boîte de montre munie d'une lunette décorative amovible, dans laquelle cette lunette décorative est retenue sur la boîte par une pluralité de moyens de fixation de type baïonnette associés à des moyens de blocage.The present invention relates to a watch case provided with a removable decorative bezel, in which this decorative bezel is retained on the case by a plurality of bayonet type fixing means associated with blocking means.
Une- lunette décorative amovible de ce type a déjà été décrite dans le EP 0" 621' 518, dans lequel cette lunette est retenue sur la boîte dans une position angulaire déterminée, par un organe de verrouillage monté coulissant dans la carrure de la boîte et est sollicité par un ressort qui tend constamment à le faire saillir de la surface de la carrure destinée à recevoir la lunette amovible en se situant à che- val entre la carrure et la lunette. Les surfaces latérales adjacentes de la carrure et de la lunette présentent chacune un évidemment, qui une fois mis en face l'un de L'autre, ménagent un passage dont la section correspond à celle de l'organe de verrouillage, de sorte que celui-ci pénètre dans ce passage dès que ces évidements sont en face l'un de l'autre et verrouille la lunette.A removable decorative bezel of this type has already been described in EP 0 "621 '518, in which this bezel is retained on the box in a determined angular position, by a locking member mounted to slide in the middle of the box and is biased by a spring which constantly tends to protrude it from the surface of the middle part intended to receive the removable bezel, lying between the middle part and the bezel. The adjacent lateral surfaces of the middle part and the bezel have each one obviously, which once placed opposite one of the other, provide a passage whose cross section corresponds to that of the locking member, so that the latter enters this passage as soon as these recesses are in facing each other and locks the bezel.
L'organe de verrouillage ressort sous la boîte et son extrémité correspondante est solidaire d'un élément de préhension destiné à permettre d'escamoter l'organe de ' ver- rouillage du passage formé entre la carrure et la lunette à 1' encontre de la pression du ressort, pour permettre d'enlever, la lunette.The locking spring member in the box and its corresponding end is integral with a gripping element for enabling to retract the organ of the locking of the passageway formed between the middle part and the bezel 1 against the spring pressure, to remove the bezel.
Cette solution comporte différents inconvénients parmi lesquels on peut citer le fait que l'organe de préhension est d'accès relativement difficile pour une personne hors du domaine horloger, ce qui est généralement le cas. En outre, cet organe de préhension doit cependant être apparent, ce qui nuit à l'aspect esthétique de la montre. Or, une montre à lunette décorative interchangeable a précisément un but esthétique, de sorte que les moyens utilisés pour permettre le changement de lunette par l'utilisateur, vont à l' encontre du but général recherché. Un autre inconvénient réside dans le fait que la lunette étant fixée par une fixation à baïonnette, un léger jeu doit forcément subsister entre la lunette et la boîte pour permettre le déplacement angulaire.de ces deux pièces. Or, étant donné que l'organe de verrouillage appuie contre la lunette en un seul endroit, un jeu apparaîtra à cet endroit, tandis qu'il diminuera au fur et à mesure que l'on s'éloigne de cet endroit pour disparaître à l'endroit diamétralement opposé, ce qui contribue à nuire à la qualité de l'esthétique. Ceci montre qu'il n'existe pas encore de ' système de lunette interchangeable répondant à l'ensemble des exigences actuelles relatives à la montre de luxe.This solution has various drawbacks, among which we can cite the fact that the gripping member is relatively difficult to access for a person outside the watchmaking field, which is generally the case. In addition, this gripping member must however be visible, which affects the aesthetic appearance of the watch. Now, a watch with interchangeable decorative bezel has precisely an aesthetic purpose, so that the means used to allow the user to change the bezel go against the general aim sought. Another disadvantage lies in the fact that the telescope being fixed by a bayonet fixing, a slight clearance must necessarily remain between the telescope and the box to allow angular movement of these two parts. However, since the locking member presses against the telescope in a single location, a clearance will appear at this location, while it will decrease as we move away from this location to disappear at the diametrically opposite place, which contributes to undermining the quality of the aesthetics. This shows that there is not yet a system of interchangeable glasses meeting all the current requirements relating to the luxury watch.
On a certes proposé différentes autres solutions, notamment des solutions ayant recours à des systèmes d'accro- chage tels que décrits dans le FR 2' 377' 057 ou dans le EP 0' 217' 465 par exemple. Toutefois avec de tels systèmes, soit la lunette est fixée solidement mais ne peut pas être enlevée sans l'aide d'un outil toujours susceptible de laisser des marques si il n'est pas utilisé par un professionnel, soit la lunette est fixée moins solidement pour pouvoir être changée à la main par un nom professionnel, mais risque alors de se détacher accidentellement. Or de telles lunettes sont susceptibles de porter des pierres plus ou moins précieuses, voire des diamants, d'où l'importance que l'inter- changeabilité de la lunette ne résulte pas dans le risque de perte de cette lunette.Various other solutions have certainly been proposed, in particular solutions using hanging systems as described in FR 2 '377' 057 or in EP 0 '217' 465 for example. However with such systems, either the telescope is fixed securely but cannot be removed without the aid of a tool always capable of leaving marks if it is not used by a professional, or the telescope is fixed less securely to be changed by hand by a professional name, but may then come off accidentally. However, such glasses are capable of wearing more or less precious stones, or even diamonds, hence the importance that the interchangeability of the bezel does not result in the risk of loss of this bezel.
On a aussi proposé dans le EP 0' 461' 069, une montre à bracelet interchangeable, dans laquelle le bracelet est retenu entre une ou deux cornes et la lunette, qui est tournante de manière à permettre d' être déplacée angulaire- ment pour libérer le bracelet, un système de blocage angulaire à bille entre cette lunette tournante et la boîte de montre. La lunette dans ce cas n'est pas amovible, au moins pas sans un outillage approprié, celle-ci étant retenue par un ressort polygonal.EP 0 '461' 069 has also proposed a watch with an interchangeable strap, in which the strap is retained between one or two horns and the bezel, which is rotating so as to allow it to be angularly moved to release the bracelet, an angular blocking system with ball between this rotating bezel and the watch case. The telescope in this case is not removable, at least not without the appropriate tools, the latter being retained by a polygonal spring.
Il ressort de l'état de la technique susmentionné que l'on n'a pas encore proposé de montre à lunette interchan- geable dont la lunette peut facilement être enlevée par l'utilisateur tout en permettant une fixation précise sûre et totalement invisible.It appears from the aforementioned state of the art that no watch with interchangeable glasses has yet been proposed, the glasses of which can easily be removed by the user while allowing precise, secure and totally invisible fixing.
Le but de la présente invention est d'apporter une solution capable de satisfaire l'ensemble des critères sus en- tionnés, alliant sécurité, esthétique, interchangeabilité à la portée de tout utilisateur sans a cun outil ni effort ou habileté particulière.The aim of the present invention is to provide a solution capable of satisfying all of the abovementioned criteria, combining security, aesthetics, interchangeability within the reach of any user without any special tool or effort or skill.
A cet effet, la présente invention a pour objet un boîte de montre munie d'une lunette décorative amovible selon la revendication 1.To this end, the present invention relates to a watch case provided with a removable decorative bezel according to claim 1.
Le dessin annexé illustre, schématiquement et à titre d'exemple, deux formes d'exécutions de la boîte de montre objet de la présente invention.The attached drawing illustrates, schematically and by way of example, two forms of execution of the watch case which is the subject of the present invention.
La figure 1 est une vue de dessus de la boîte sans la lunette amovible, selon la première forme d'exécution ; la figure 2 est une vue en coupe selon la coupe II-II de la figure 1 ; la figure 3 est une vue en coupe selon la coupe III-III de la figure 1 ; la figure 4 est une vue en coupe selon la coupe IV-IV de la figure 1 ; la figure 5 est une vue de dessous de la lunette amovible destinée à la boîte de la figure 1; la figure .6 est une vue selon la coupe VI-VI de la figure 5 ; la figure 7 est une vue en coupe selon la figure VII- VII de la figure ; la figure 8 est une vue de dessus d'une boîte sans la lunette amovible, selon la seconde forme d'exécution ; la figure 9 est une vue en coupe selon la coupe IX-IX de la figure 8 ; la figure 10 est une vue' en coupe selon la coupe X-X de la figure 8 ; la figure 11 est une vue en coupe selon la coupe XI-XI de la figure 8 ; la figure 12 est une vue de dessous de la lunette amovible ; la figure 13 est une vue en coupe selon la coupe XIII- XIII de la figure 12 ; la figure 14 est une vue en coupe selon la coupe XIV- XIV de la figure 12.Figure 1 is a top view of the box without the removable window, according to the first embodiment; Figure 2 is a sectional view along section II-II of Figure 1; Figure 3 is a sectional view along section III-III of Figure 1; Figure 4 is a sectional view along section IV-IV of Figure 1; Figure 5 is a bottom view of the removable window for the box of Figure 1; Figure .6 is a view along section VI-VI of Figure 5; Figure 7 is a sectional view according to Figure VII-VII of the figure; Figure 8 is a top view of a box without the removable window, according to the second embodiment; Figure 9 is a sectional view along section IX-IX of Figure 8; Figure 10 is a sectional view along section XX of Figure 8; Figure 11 is a sectional view along section XI-XI of Figure 8; Figure 12 is a bottom view of the removable window; Figure 13 is a sectional view along section XIII-XIII of Figure 12; FIG. 14 is a sectional view along the section XIV-XIV of FIG. 12.
La boîte de montre illustrée ' par les figures 1 à 4 comporte essentiellement une carrure 1 dont la face supérieure présente, dans cet exemple quatre logements 2 diamétralement opposés deux à deux. L'un de ces logements est illustré par la figure 2. Il renferme une douille 3 dans laquelle une bille 4 est logée et retenue par un rebord 3a de la douille 3 et pressée contre ce rebord 3a par un ressort 5.The watch case illustrated 'by Figures 1 to 4 essentially comprises a case 1 whose upper face has, in this example four housings two diametrically opposed in pairs. One of these housings is illustrated in FIG. 2. It contains a socket 3 in which a ball 4 is housed and retained by a flange 3a of the socket 3 and pressed against this flange 3a by a spring 5.
Deux gorges en arc de cercle 6 sont ménagées dans la face supérieure de la carrure 1. Le profil de ces rainures 6 correspond à celui illustré par la figure 3, c'est-à-dire qu'il comporte une partie large 6a formant le fond.de la gorge et une partie plus étroite 6b s' ouvrant sur la face supérieure de la carrure. Ces deux gorges 6 sont disposées chacune entre deux logements 2 à billes 4. A chaque extrémi- té de ces gorges 6, dans deux positions diamétralement opposées, ces gorges 6 comportent chacune une ouverture d'entrée 9 (figure 4) dont le diamètre correspond à la plus grande largeur de la gorge 6, celle de la partie 6a. Comme le montre la figure 5, une lunette amovible 7 comporte deux pieds 8 diamétralement opposés, qui font saillie de sa face inférieure. Chacun de ces pieds 8 présente deux parties, l'une '8a, de grand diamètre, l'autre 8b de plus petit diamètre, ces pieds reproduisant sensiblement le profil des gorges 6. La face inférieure de la lunette 7 comporte encore quatre empreintes hémisphériques 10, diamétralement opposées deux à deux. Les positions angulaires relatives de ces empreinte hémisphériques 10 et des pieds 8, correspondent aux positions relatives des logements 2 et des ouvertures d'entrées 9 de la carrure' 1.Two grooves in an arc of a circle 6 are formed in the upper face of the middle part 1. The profile of these grooves 6 corresponds to that illustrated in FIG. 3, that is to say that it comprises a wide part 6a forming the fond.de the throat and a narrower part 6b opening on the upper face of the middle part. These two grooves 6 are each disposed between two housings 2 with balls 4. At each extremi- tee of these grooves 6, in two diametrically opposite positions, these grooves 6 each have an inlet opening 9 (Figure 4) whose diameter corresponds to the largest width of the groove 6, that of the part 6a. As shown in Figure 5, a removable window 7 has two diametrically opposite feet 8, which project from its underside. Each of these feet 8 has two parts, one ' 8a, of large diameter, the other 8b of smaller diameter, these feet substantially reproducing the profile of the grooves 6. The underside of the bezel 7 still has four hemispherical imprints 10, diametrically opposite two by two. The relative angular positions of these hemispherical footprints 10 and of the legs 8, correspond to the relative positions of the housings 2 and of the inlet openings 9 of the middle part ' 1.
Grâce à cette disposition, les deux pieds 8 de la lunette 7 peuvent être engagés dans les gorges 6 respectives. Une fois que ces pieds sont engagés dans ces gorges 6, la face inférieure de la lunette 7 presse les billes 4 dans leurs douilles respectives 3 à l' encontre de la pression des ressorts 5. Ensuite on tourne la lunette 7 dans le sens des aiguilles de la montre (figure 1) jusqu'à ce que les pieds 8 arrivent à l'autre extrémité des gorges 6. A ce moment, les empreintes hémisphériques 10 arrivent en face des logements 2, de sorte que les billes 4 sont poussées dans ces empreintes 10 servant au blocage angulaire de la lunette 7, qui ne pourra alors être dégagée et enlevée que si une force angulaire suffisante et- de sens opposé est appliquée à cette lunette 7. Comme on peut le constater, les billes 4 servent non seulement au positionnement de la lunette 7, mais leur répartition applique une pression également répartie sur la lunette tendant à l'éloigner de la carrure, mais comme cette pression est également répartie. Le petit jeu qui existe forcément entre ces deux pièces est constant sur tout le pourtour de la lunette 7. Ces billes 4 servent aussi d'éléments de roulement lors de la rotation de- la lunette 7, rendant la mise en place et l'enlèvement de celle-ci plus agréable.Thanks to this arrangement, the two feet 8 of the bezel 7 can be engaged in the respective grooves 6. Once these feet are engaged in these grooves 6, the underside of the bezel 7 presses the balls 4 in their respective sockets 3 against the pressure of the springs 5. Then the bezel 7 is turned clockwise of the watch (Figure 1) until the feet 8 arrive at the other end of the grooves 6. At this time, the hemispherical imprints 10 arrive opposite the housings 2, so that the balls 4 are pushed into these fingerprints 10 used for angular blocking of the telescope 7, which can then be released and removed only if a sufficient angular force and- in the opposite direction is applied to this telescope 7. As can be seen, the balls 4 are used not only for positioning of the bezel 7, but their distribution applies an evenly distributed pressure on the bezel tending to move it away from the middle part, but like this pressure is evenly distributed. The small clearance which necessarily exists between these two parts is constant over the entire periphery of the telescope 7. These balls 4 also serve as rolling elements during the rotation of the telescope 7, making the installation and removal of it more pleasant.
La seconde forme d'exécution illustrée par les figures 8 à L4 ne diffère de la première essentiellement par le fait que la boîte 11 n'est par ronde mais polygonale, ici carrée ou rectangulaire, de sorte que pour fixer la lunette amovible 17, le mouvement sera rectiligne au lieu d'être un mouvement angulaire.The second embodiment illustrated by FIGS. 8 to L4 differs from the first essentially by the fact that the box 11 is not round but polygonal, here square or rectangular, so that to fix the removable window 17, the movement will be rectilinear instead of being an angular movement.
Une autre différence réside dans le fait que la lunette 17 porte quatre pieds 18 au lieu de deux pour assurer une meilleure stabilité de la lunette 18: De ce fait, les gorges 16 ménagées dans la carrure comportent chacune deux ouvertures d'entrées 19a, 19b. Dans cette variante, les billes 14 dans les logement 12 sont disposées aux quatre angles de la boîte 1 et les empreintes hémisphériques 20 aux quatre angles de la lunette 17.Another difference lies in the fact that the bezel 17 carries four feet 18 instead of two to ensure better stability of the bezel 18: As a result, the grooves 16 formed in the middle each have two inlet openings 19a, 19b . In this variant, the balls 14 in the housings 12 are arranged at the four angles of the box 1 and the hemispherical imprints 20 at the four angles of the bezel 17.
De préférence, étant donné que la glace de montre doit •être fixée dans la carrure de boîte 11, au niveau de la face supérieure de cette carrure de boîte 11, pour permettre le déplacement de la lunette 17, cette dernière portera égale- ment une glace pour des raisons esthétiques. Preferably, since the watch crystal must be • fixed in the case middle 11, at the level of the upper face of this case middle 11, to allow the movement of the bezel 17, the latter will also carry a ice for aesthetic reasons.
