One series of holes is provided for screwing in a series of screws for fixing a moving mechanism (1) onto the bezel. The angularly offset other series of holes passes through the moving mechanism for screwing the back cover (2) into the lower bezel portion.

Description

La présente invention a pour objet une boíte de montre dont les éléments constitutifs sont rendus solidaires les uns des autres par l'intermédiaire de la lunette. L'invention concerne plus particulièrement une boíte de montre pouvant être classée dans la catégorie dite "trois pièces", c'est-à-dire une boíte comportant une lunette, une carrure et un fond indépendants qui après assemblage délimitent avec la glace un espace dans lequel est logé un mouvement permettant un affichage digital ou analogique de l'heure sur un cadran disposé en dessous de la glace.The present invention relates to a watch case whose elements components are made integral with each other by means of the telescope. The invention relates more particularly to a watch case which can be classified in the category called "three pieces", that is to say a box comprising a telescope, an independent middle and back which, after assembly, delimit with the crystal a space in which a movement is housed allowing digital display or analog of the time on a dial arranged below the glass.

Pour rendre ces trois pièces solidaires, dans les très nombreux dispositifs déjà proposés, la carrure constitue généralement l'élément essentiel permettant la fixation de la lunette et du fond par vissage, par chassage, voire par collage.To make these three pieces integral, in the very many devices already offered, the middle part generally constitutes the essential element allowing the fixing of the bezel and the back by screwing, by driving out, even by gluing.

Il est par exemple possible de prévoir dans la carrure, d'un côté une première série de trous pour le vissage de la lunette, et de l'autre une deuxième série de trous pour le vissage du fond, le mouvement ou le cercle d'emboítage le contenant étant alors calé par des épaulements appropriés de la carrure.It is for example possible to provide in the middle, on one side a first series of holes for screwing on the telescope, and on the other a second series of holes for screwing the bottom, the movement or the casing circle containing it then wedged by appropriate shoulders of the middle.

Dans le brevet CH 645 497, il n'est prévu qu'une seule série de trous pour recevoir une première vis servant à fixer la lunette et dont la tête taraudée et noyée dans la carrure permet le vissage d'une deuxième vis pour la fixation du fond, les deux vis ayant des pas contraires. Cet assemblage gigogne peut faire croire que la lunette est l'élément essentiel d'assemblage, mais on voit bien que la carrure est indispensable pour fermer le pourtour de la boíte et pour permettre la mise en place d'un mouvement.In patent CH 645 497, only one series of holes is provided for receive a first screw used to fix the telescope and whose tapped and submerged head in the middle allows the screwing of a second screw for fixing the bottom, the two screws with opposite pitches. This pull-out assembly may suggest that the bezel is the essential element of assembly, but we can clearly see that the middle is essential to close the perimeter of the box and to allow the establishment of a movement.

La boíte de montre décrite dans le brevet EP 0 443 366 est composée de deux coquilles réunies par une carrure, la coquille inférieure formant un fond vissé et la coquille supérieure étant en fait une mince glace-lunette collée.The watch case described in patent EP 0 443 366 is composed of two shells joined by a middle part, the lower shell forming a screwed bottom and the upper shell being in fact a thin bonded glass-bezel.

La boíte de montre selon la présente invention permet au contraire d'avoir un assemblage des différents éléments constitutifs, sans faire intervenir la carrure comme élément mécanique de liaison. La carrure garde toutefois un rôle fonctionnel notamment pour renforcer l'étanchéité et pour permettre la fixation des brins de bracelet. N'ayant pas de fonction mécanique elle peut également être réalisée de façon plus simple et plus économique, par exemple par moulage ou injection d'une matière plastique et procurer ainsi une grande liberté de choix au niveau de l'assortiment d'une collection.The watch case according to the present invention allows on the contrary to have a assembly of the various constituent elements, without involving the middle as a mechanical connecting element. The middle part retains a functional role in particular to reinforce the sealing and to allow the fixing of the strands of bracelet. Having no mechanical function, it can also be made of simpler and more economical, for example by molding or injection of a plastic and thus provide great freedom of choice in terms of assortment of a collection.

A cet effet, l'invention a pour objet une boíte de montre comprenant un fond, une carrure et une lunette fermée par une glace délimitant ensemble un espace dans lequel est logé un mouvement d'horlogerie supporté par une platine et permettant un affichage analogique ou digital de l'heure sur un cadran disposé en dessous de la glace. La construction de cette boíte est caractérisée en ce que la lunette constitue l'élément essentiel d'assemblage. Pour cela la lunette est réalisée en métal en ayant localement un anneau d'épaisseur suffisante pour permettre l'exécution de séries de perçages borgnes dans sa partie inférieure. Une première série de trous taraudés est destinée au vissage d'une première série de vis pour la fixation du mouvement sur la lunette. Une deuxième série de trous taraudés, décalés angulairement par rapport à la première série, traversant le mouvement, est destinée au vissage du fond dans la partie inférieure de la lunette.To this end, the invention relates to a watch case comprising a case back, a middle part and a bezel closed by a crystal together delimiting a space in which is housed a clockwork movement supported by a plate and allowing a analog or digital time display on a dial located below the ice cream. The construction of this box is characterized in that the bezel constitutes the essential element of assembly. For this the bezel is made of metal having locally a ring of sufficient thickness to allow the execution of series of blind holes in its lower part. A first series of tapped holes is intended for the screwing of a first series of screws for fixing the movement to the glasses. A second series of tapped holes, angularly offset from the first series, crossing the movement, is intended for screwing the bottom into the lower part of the bezel.

Pour avoir une plus grande précision de positionnement du mouvement, il est en outre possible de prévoir également dans le fond de la lunette deux trous borgnes dans lesquels viendront s'engager deux goupilles montées sur le mouvement.To have greater precision in positioning the movement, it is in addition possible to also provide in the bottom of the telescope two blind holes in which will engage two pins mounted on the movement.

La lunette, le mouvement et le fond forment ainsi un ensemble parfaitement rigide insensible aux ondes de choc susceptibles de déstabiliser les parties fragiles du mouvement. Il va de soi que l'assemblage de ces trois éléments s'effectue en interposant la carrure qui, n'ayant plus de fonction d'assemblage, peut être flottante entre des joints d'étanchéité prévus au niveau de la carrure et du fond et permettre l'attache de brins de bracelet.The bezel, the movement and the case back form a perfectly combined whole. rigid insensitive to shock waves likely to destabilize the fragile parts of the movement. It goes without saying that these three elements are assembled in interposing the middle part which, no longer having an assembly function, can be floating between seals provided at the middle and the bottom and allow the bracelet strands attachment.

Pour fixer le mouvement et le fond sur la lunette il est prévu, en regard des deux séries de trous taraudés, des trous soit dans la platine supportant les éléments du mouvement, soit dans un cercle d'emboítage de ladite platine.To fix the movement and the back on the bezel, it is provided, opposite the two sets of tapped holes, either in the plate supporting the elements of movement, either in a casing circle of said plate.

D'autres caractéristiques et avantages de la présente invention apparaítront plus clairement à la lecture de la description détaillée d'un mode de réalisation d'une boíte de montre à affichage analogique, en référence aux dessins annexés dans lesquels :

  • la figure 1 est une vue de dessous de la boíte de montre;
  • la figure 2 est une vue en coupe brisée selon la ligne II-II de la figure 1, et
  • la figure 3 est une vue en coupe brisée selon la ligne III-III de la figure 1.
Other characteristics and advantages of the present invention will appear more clearly on reading the detailed description of an embodiment of a watch case with analog display, with reference to the accompanying drawings in which:
  • Figure 1 is a bottom view of the watch case;
  • FIG. 2 is a broken sectional view along the line II-II of FIG. 1, and
  • Figure 3 is a broken sectional view along line III-III of Figure 1.

En se référent d'abord aux figures 1 et 2, on voit qu'on a représenté une montre-bracelet à affichage analogique au moyen de l'aiguille des heures 7, de l'aiguille des minutes 8 et d'une aiguille de petite seconde 9. Dans la vue de dessous représentée à la figure 1, on a supposé que le fond était entièrement transparent pour montrer la répartition angulaire des moyens de fixation 10, 20, 30 sur la lunette 4. Dans l'exemple représenté, la boíte est conçue pour une montre dite "squelette", c'est-à-dire dans laquelle les mobiles (non représentés) du mouvement 1 sont apparents. Referring first to Figures 1 and 2, we see that a wristwatch with analog display using the hour hand 7, the minute hand 8 and a small second hand 9. In the bottom view shown in Figure 1, it was assumed that the bottom was completely transparent for show the angular distribution of the fixing means 10, 20, 30 on the telescope 4. In the example shown, the box is designed for a watch called "skeleton", that is to say in which the mobiles (not shown) of movement 1 are apparent.

La boíte se compose d'un fond 2, d'une carrure 3 et d'une lunette 4 fermée par une glace 5 avec interposition d'un joint 15. Le fond 2 peut évidemment être réalisé en une seule pièce, mais dans un modèle "squelette" le fond 2 est de préférence formé par un anneau extérieur 12, ledit anneau étant de préférence opaque pour masquer des éléments de fixation ou d'étanchéité, et par un disque transparent 22 bloqué dans l'anneau 12 par des joints 16. Le disque transparent 22 a sensiblement le même diamètre que la glace 5, voire un peu inférieur et peut être réalisé dans le même matériau que la glace 5. Le fond 2, ou l'anneau de fond 12, peut être réalisé en un matériau quelconque suffisamment rigide, mais il sera de préférence en métal pour garantir une meilleure cohésion des éléments assemblés.The box consists of a base 2, a middle part 3 and a bezel 4 closed by a window 5 with interposition of a seal 15. The bottom 2 can obviously be produced by one piece, but in a "skeleton" model the bottom 2 is preferably formed by an outer ring 12, said ring being preferably opaque to mask fixing or sealing elements, and by a transparent disc 22 locked in the ring 12 by seals 16. The transparent disc 22 has substantially the same diameter than glass 5, even a little smaller and can be made in the same material as the glass 5. The bottom 2, or the bottom ring 12, can be made in one any sufficiently rigid material, but preferably metal guarantee better cohesion of the assembled elements.

La lunette 4 est, selon une caractéristique de l'invention réalisée en métal et possède un anneau de matière 14 d'épaisseur suffisante pour pouvoir y réaliser des perçages borgnes, comme représentés sur les figures 2 et 3. La figure 2 représente une coupe brisée selon la ligne II-II de la figure 1, passant par le centre et par deux types de fixation. Dans la partie droite on a représenté la fixation du mouvement 1 à la lunette 4 au moyen d'une première série de vis 10 vissées dans des trous taraudés 11 de la lunette 4. Dans l'exemple représenté, comme on le voit à la figure 1, cette fixation est effectuée en trois points régulièrement répartis autour de l'anneau 14. Cette fixation est effectuée à travers des perçages 11a prévus dans le support du mouvement 1, qui peut être soit la platine elle même (non représentée) supportant le mouvement 1, soit un cercle d'encageage (non représenté) auquel le mouvement 1 est assujetti. La platine ou le cercle d'encageage sont bloqués par les vis 10 sur un anneau de la face inférieure de la lunette 4 ayant de préférence au-delà de l'anneau 14 une extension 24 dirigée vers le centre de la montre, ladite extension 24 contribuant à rigidifier la lunette 4 et à garantir ainsi la précision de l'assemblage du mouvement 1 sur ladite lunette 4. Dans l'exemple de la montre "squelette" représentée, l'extension 24 sera avantageusement limité à un anneau ayant de préférence une surface 25 inclinée vers le centre de la montre, ce qui permet d'avoir une meilleure lisibilité des indices horaires rapportés sur ladite surface 25, tout en laissant parfaitement visible dans une ouverture centrale 26 le mouvement, et en particulier les rouages. Dans le cas d'une montre "non squelette", l'anneau 24 peut être prolongé jusqu'au trou des aiguilles 7, 8 et former ainsi une lunette-cadran. L'ouverture centrale 26 peut également être obturée par un disque opaque indépendant de l'extension annulaire 24.The bezel 4 is, according to a characteristic of the invention made of metal and has a ring of material 14 of sufficient thickness to be able to carry out blind holes, as shown in Figures 2 and 3. Figure 2 shows a broken section along line II-II of Figure 1, passing through the center and through two attachment types. In the right part, the attachment of movement 1 to the bezel 4 by means of a first series of screws 10 screwed into tapped holes 11 bezel 4. In the example shown, as seen in Figure 1, this fixing is carried out at three points regularly distributed around the ring 14. This fixing is carried out through holes 11a provided in the support of the movement 1, which can either be the plate itself (not shown) supporting the movement 1, i.e. a casing circle (not shown) to which movement 1 is subject. The plate or the casing ring are locked by the screws 10 on a ring on the underside of the bezel 4 preferably having beyond the ring 14 an extension 24 directed towards the center of the watch, said extension 24 helping to stiffen the bezel 4 and thus guarantee the precision of the assembly of the movement 1 on said bezel 4. In the example of the "skeleton" watch shown, the extension 24 will advantageously be limited to a ring having preferably a surface 25 inclined towards the center of the watch, which makes it possible to have better readability of the hourly indices reported on said surface 25, while leaving perfectly visible in a central opening 26 the movement, and especially the cogs. In the case of a "non-skeleton" watch, the ring 24 can be extended to the hole of the needles 7, 8 and thus form a bezel-dial. The central opening 26 can also be closed off by an opaque disc independent of annular extension 24.

En se référant également à la figure 3, on voit que le positionnement du mouvement 1 sur la lunette 4 peut être rendu plus précis grâce à deux goupilles 30 solidaires du mouvement 1 et venant s'engager dans des trous borgnes 31 de la lunette 4. Les goupilles 30 sont représentées en position diamétrale, mais elles pourraient évidemment avoir un autre positionnement angulaire, à condition de ne pas coïncider avec la première série de vis 10.Referring also to FIG. 3, it can be seen that the positioning of the movement 1 on the bezel 4 can be made more precise thanks to two pins 30 integral with movement 1 and coming to engage in blind holes 31 of the bezel 4. The pins 30 are shown in diametrical position, but they could obviously have another angular positioning, provided they do not coincide with the first set of screws 10.

Une deuxième série de vis 20 sert à fixer le fond 2 par vissage dans des trous taraudés 21 de la lunette 4. Comme on le voit à la figure 3, à titre d'exemple, on peut avoir huit fixations angulairement régulièrement réparties et décalées par rapport à la première série de vis 10. Les vis 20 traversent le fond 2 dans sa partie annulaire 12, puis le mouvement 1 à travers des trous 21a prévus dans la platine ou le cercle d'encageage. Les trous 21a sont prévus avec un léger jeu de sorte que le vissage des vis 20 ne compromette pas l'ajustement du mouvement 1 sur la lunette 4.A second series of screws 20 is used to fix the bottom 2 by screwing in holes threaded 21 of the bezel 4. As seen in Figure 3, for example, we can have eight fixtures angularly evenly distributed and offset from the first series of screws 10. The screws 20 pass through the bottom 2 in its annular part 12, then movement 1 through holes 21a provided in the plate or the circle Casing. The holes 21a are provided with a slight clearance so that the screwing of the screw 20 does not compromise the adjustment of movement 1 on the bezel 4.

Le montage qui vient d'être décrit est effectué en interposant la carrure 3 avant la fixation du fond 2. Cette carrure n'intervenant plus dans le positionnement et la fixation du mouvement 1 peut avoir une forme simple comportant essentiellement des moyens de fixation 13 de brins de bracelet et des moyens permettant de renforcer l'étanchéité. A cet effet, la partie inférieure de la carrure 3 comporte une gorge annulaire 36 destinée à recevoir un joint 32 venant en appui sur la surface supérieure de l'anneau extérieur 12 du fond 2. De même, le bord interne supérieur de la carrure comporte un dégagement annulaire 37 destiné à recevoir un joint 33 venant en appui sur la surface inférieure de l'extension 34 de la lunette 4. Cette extension 34 comporte également à son extrémité un bec annulaire 39 venant s'engager dans une rainure correspondante 37 de la carrure 3. Bien que cela ne puisse être rendu visible sur les figures 2 et 3, on choisit de préférence la hauteur totale de la carrure 3 et l'épaisseur des joints 32 et 33 de telle sorte qu'il subsiste un faible jeu entre la carrure 3 et d'une part le fond 2, d'autre part la lunette 4.The assembly which has just been described is carried out by interposing the middle part 3 before fixing the back 2. This middle part no longer intervenes in the positioning and fixation of movement 1 can have a simple form essentially comprising fixing means 13 of bracelet strands and means making it possible to reinforce sealing. For this purpose, the lower part of the middle part 3 has a groove annular 36 intended to receive a seal 32 bearing on the upper surface of the outer ring 12 of the base 2. Similarly, the upper internal edge of the middle part comprises an annular clearance 37 intended to receive a seal 33 which comes to bear on the lower surface of the extension 34 of the telescope 4. This extension 34 comprises also at its end an annular spout 39 coming to engage in a groove corresponding 37 of the middle 3. Although this cannot be made visible on the Figures 2 and 3, the total height of the middle part 3 and the thickness are preferably chosen seals 32 and 33 so that there is a slight clearance between the middle part 3 and a share the bottom 2, on the other hand the bezel 4.

La carrure 3 est donc en quelque sorte montée flottante entre ces deux éléments d'assemblage de la boíte et peut ainsi avoir une fonction d'amortisseur de chocs. On observera également que cette construction permet d'avoir des tolérances de fabrication de la carrure assez larges, et de pouvoir la réaliser par exemple par moulage ou injection d'un matériau plastique dont il est très facile de modifier la coloration par exemple pour une collection donnée.The middle 3 is therefore somehow mounted floating between these two assembly elements of the box and can thus have a damping function of shocks. It will also be observed that this construction makes it possible to have tolerances manufacturing the fairly wide middle, and being able to make it for example by molding or injection of a plastic material which it is very easy to modify coloring for example for a given collection.

On comprendra facilement que l'exemple qui vient d'être décrit n'est pas limité à une montre bracelet à affichage analogique de l'heure, et que l'homme de métier peut sans sortir du cadre de la présente invention adapter les caractéristiques de la boíte à une quelconque pièce d'horlogerie donnant de façon analogique ou digitale des informations horaires ou non horaires.It will be readily understood that the example which has just been described is not limited to a wristwatch with analog time display, and that the skilled person can without departing from the scope of the present invention adapt the characteristics of the box to any timepiece giving analog or digital hourly or non-hourly information.
