The invention is characterised in that said ring-shaped disks (11, 12) are arranged in a common plane, the outer disk (12) displaying minutes, being driven by means of a pinion (16) co-operating with teeth on the external periphery of said outer disk, and the inner disk (11) displaying hours, being driven by means of a pinion (14) co-operating with teeth on the internal periphery of said inner disk.

Description

Montre à affichage analogique Analog display watch
La présente invention concerne une montre à affichage analogique comportant au moins deux disques indicateurs annulaires, coaxiaux, entraînés en rotation autour de leur axe commun par un mouvement d'horlogerie, ces disques et ce mouvement d'horlogerie étant logés dans un boîtier présentant au moins une ouverture qui le traverse de part en part dans le sens dudit axe.The present invention relates to a watch with analog display comprising at least two annular, coaxial indicator discs driven in rotation about their common axis by a clockwork movement, these discs and this clockwork movement being housed in a housing having at least an opening which passes right through it in the direction of said axis.
Il est à noter que l'on entend par "ouverture" traversant le boîtier, une ouverture ou trou traversant la montre du point de vue visuel, indépendamment d'éventuels éléments transparents qui pourraient couvrir, ou être insérés dans l'espace de l'ouverture qui reste ainsi ouvert à la vue et ne comporte aucun élément fonctionnel de la montre.It should be noted that the term “opening” passing through the case means an opening or hole passing through the watch from a visual point of view, independently of any transparent elements which could cover, or be inserted into the space of the opening which thus remains open to view and contains no functional element of the watch.
Une montre du type susmentionné a été décrite par exemple dans le brevet suisse N° 680 486. La montre selon ce brevet présente toutefois l'inconvénient majeur de conduire nécessairement à une forme relativement allongée, ce qui nuit considérablement à l'esthétique de la montre et la rend difficilement portable pour des personnes ayant un poignet petit. D'autre part, cette montre comporte des disques indicateurs superposés de sorte que le disque supérieur doit être au moins partiellement transparent pour qu'un index sur le disque inférieur soit lisible.A watch of the aforementioned type has been described for example in Swiss patent N ° 680,486. The watch according to this patent however has the major drawback of necessarily leading to a relatively elongated shape, which considerably harms the aesthetics of the watch and makes it difficult to portable for people with a small wrist. On the other hand, this watch has indicator discs superimposed so that the upper disc must be at least partially transparent for an index on the lower disc to be readable.
La présente invention vise notamment à remédier à ces inconvénients en fournissant une montre qui, tout en présentant ladite ouverture du boîtier, puisse être réalisée sous une forme telle que la plus grande dimension de la montre dans un plan perpendiculaire à l'axe mentionné soit sensiblement réduite, de manière à rendre la montre plus esthétique et mieux adaptée au poignet. En outre, l'invention vise à améliorer la lisibilité et l'esthétisme de l'affichage en permettant une finition des disques et des index qui ne soit pas limitée par les contraintes de la montre proposée selon le brevet susmentionné.The present invention aims in particular to remedy these drawbacks by providing a watch which, while having said opening of the case, can be produced in a form such that the largest dimension of the watch in a plane perpendicular to the mentioned axis is substantially reduced, so as to make the watch more aesthetic and better suited to the wrist. In addition, the invention aims to improve the readability and the aesthetics of the display allowing a finishing of the discs and indexes which is not limited by the constraints of the watch proposed according to the aforementioned patent.
A cet effet, la montre selon l'invention présente les particularités indiquées dans la partie caractérisante de la revendication 1.To this end, the watch according to the invention has the features indicated in the characterizing part of claim 1.
Les revendications 2 et 3 décrivent des formes d'exécution préférées de la montre selon l'invention. Ces formes d'exécution permettent notamment de fabriquer la boîte de montre par les moyens usuels de fabrication de boîtes de montre, et de fabriquer le support des parties mobiles selon les règles et tolérances usitées dans la fabrication des platines horlogères. Ceci conduit à une réduction sensible des coûts de fabrication et permet en particulier de tester séparément le train d'engrenage, celui-ci ne dépendant plus de la boîte de montre.Claims 2 and 3 describe preferred embodiments of the watch according to the invention. These embodiments make it possible in particular to manufacture the watch case by the usual means for manufacturing watch cases, and to manufacture the support for the mobile parts according to the rules and tolerances used in the manufacture of watch plates. This leads to a significant reduction in manufacturing costs and in particular allows the gear train to be tested separately, it no longer depending on the watch case.
D'autres caractéristiques, buts et avantages de l'invention ressortiront de la description d'une forme de réalisation donnée ci-après à titre d'exemple et illustrée dans les dessins annexés dans lesquels:Other characteristics, objects and advantages of the invention will emerge from the description of an embodiment given below by way of example and illustrated in the appended drawings in which:
la Fig. 1 est une vue de dessus d'une montre selon l'invention; etFig. 1 is a top view of a watch according to the invention; and
la Fig. 2 est une vue en coupe selon la ligne ll-ll de la Fig. 1.Fig. 2 is a sectional view along the line II-II of FIG. 1.
La montre représentée quelque peu schématiquement dans les figures 1 et 2 présente un élément esthétique caractéristique sous la forme d'une ouverture 1 traversant la montre de part en part. Le boîtier de cette montre comporte essentiellement trois parties entourant cette ouverture, à savoir une partie annulaire extérieure 2, une partie intérieure 3 et une glace annulaire 4 réunissant ces parties extérieure et intérieure. Cette glace 4 est insérée entre deux surfaces annulaires, à savoir une surface annulaire extérieure 5 formée par une bague 6 solidaire de la partie annulaire extérieure 2, et une surface annulaire 7 formée sur le pourtour extérieur de la partie intérieure 3.The watch shown somewhat schematically in Figures 1 and 2 has a characteristic aesthetic element in the form of an opening 1 passing right through the watch. The case of this watch essentially comprises three parts surrounding this opening, namely an external annular part 2, an internal part 3 and an annular crystal 4 joining these external and internal parts. This glass 4 is inserted between two annular surfaces, namely an outer annular surface 5 formed by a ring 6 integral with the outer annular part 2, and an annular surface 7 formed on the outer periphery of the inner part 3.
Le boîtier ainsi réalisé présente un compartiment 8 fermé par une partie de fond 9 fixée sur ce boîtier par des vis 10.The housing thus produced has a compartment 8 closed by a bottom portion 9 fixed to this housing by screws 10.
Le dispositif d'affichage de cette montre comporte deux disques indicateurs annulaires disposés essentiellement dans un même plan, à savoir un disque intérieur 11 et un disque coaxial extérieur 12.The display device of this watch comprises two annular indicator discs arranged essentially in the same plane, namely an inner disc 11 and an outer coaxial disc 12.
Le disque intérieur 11 porte un repère 13 servant à l'indication des heures et est entraîné par un pignon 14 coopérant avec une denture intérieure de ce disque.The internal disc 11 carries a mark 13 used for the indication of the hours and is driven by a pinion 14 cooperating with an internal toothing of this disc.
Le disque extérieur 12 porte un repère 15 servant à l'indication des minutes et est entraîné par un pignon 16 coopérant avec une denture extérieure du disque 12. Le pignon 16 est solidaire d'un pignon coaxial 17 entraîné par une roue 18, cette dernière étant montée, comme le pignon 14, sur l'axe principal 19 d'un mouvement d'horlogerie usuel 20. Les pignons 16 et 17 sont montés sur une partie de pont 21 qui est solidaire d'une pièce de support annulaire 27 fixée dans la partie annulaire extérieure 2 du boîtier. La pièce 27 comporte des parties de support telles que 22, 23 et des parties de guidage telles que 22', 23' pour les disques 11 et 12 disposés de façon rotative dans la partie supérieure du logement 8 formé par les pièces 2 et 3. La pièce 27 sert également de support pour le mouvement d'horlogerie 20 de manière à former, avec les parties mobiles 11 , 12, 14, 16, 17, 18, un ensemble pouvant fonctionner indépendamment du boîtier. Les figures montrent également une partie de remontoir 24 accessible par l'ouverture 1 du boîtier, et deux parties d'attache d'un bracelet 25 et 26.The outer disc 12 carries a mark 15 used for the indication of the minutes and is driven by a pinion 16 cooperating with an external toothing of the disc 12. The pinion 16 is integral with a coaxial pinion 17 driven by a wheel 18, the latter being mounted, like the pinion 14, on the main axis 19 of a usual clockwork movement 20. The pinions 16 and 17 are mounted on a bridge part 21 which is integral with an annular support piece 27 fixed in the outer annular part 2 of the housing. The part 27 comprises support parts such as 22, 23 and guide parts such as 22 ′, 23 ′ for the disks 11 and 12 arranged in a rotary manner in the upper part of the housing 8 formed by the parts 2 and 3. The part 27 also serves as a support for the clockwork movement 20 so as to form, with the moving parts 11, 12, 14, 16, 17, 18, an assembly which can operate independently of the case. The figures also show a winding part 24 accessible through the opening 1 of the case, and two parts for attaching a bracelet 25 and 26.
Les repères 13 et 15 sont visibles à travers la glace 4 et affichent, respectivement, les heures et les minutes par rapport à des marquages correspondants formés par exemple, d'une part, sur les surfaces visibles d'une portion 2' de la partie 2 et, d'autre part, sur la surface extérieure de la bague 6.The marks 13 and 15 are visible through the glass 4 and display, respectively, the hours and the minutes with respect to corresponding markings formed for example, on the one hand, on the visible surfaces of a portion 2 'of the part 2 and, on the other hand, on the outer surface of the ring 6.
Il ressort du présent exemple que la montre selon l'invention présente une dimension maximale, dans le plan des disques d'affichage, qui est sensiblement réduite, tout en permettant une réalisation esthétique très caractéristique basée sur l'ouverture traversant la montre. Grâce à la structure du présent boîtier et au fait que l'ensemble du mouvement comprenant toutes les parties mobiles est indépendant de ce boîtier dans lequel il est simplement posé, le coût de fabrication d'une telle montre peut être considérablement réduit. It appears from the present example that the watch according to the invention has a maximum dimension, in the plane of the display discs, which is significantly reduced, while allowing a very characteristic aesthetic embodiment based on the opening passing through the watch. Thanks to the structure of the present case and the fact that the entire movement comprising all the moving parts is independent of this case in which it is simply placed, the cost of manufacturing such a watch can be considerably reduced.
