Description

La présente invention concerne une pièce d'horlogerie, telle qu'une montre-bracelet, dont le mouvement est tenu à l'intérieur de la boîte par un support élastique amortisseur servant à protéger le mouvement contre les chocs.The present invention relates to a timepiece, such as a wristwatch, whose movement is held inside the box by a shock absorbing elastic support for protecting the movement against shocks.

Des pièces d'horlogerie de ce type sont décrites dans les documents CH 490 709 et CH 524 177 .Timepieces of this type are described in the documents CH 490 709 and CH 524 177 .

Dans une telle pièce d'horlogerie, la tige de remontoir et de mise à l'heure peut être soumise à des contraintes de flexion élevées en cas de choc entraînant un déplacement du mouvement à l'intérieur de la boîte. Ces contraintes peuvent endommager le mécanisme de remontage et de mise à l'heure dans le mouvement.In such a timepiece, the winding and time setting rod can be subjected to high bending stresses in the event of shock causing a movement movement inside the box. These stresses can damage the mechanism of winding and setting time in the movement.

On connaît par le document FR 2 463 437 une pièce d'horlogerie dont le mouvement est tenu par un support élastique amortisseur annulaire qui comporte une saillie radiale définissant un manchon d'étanchéité interposé entre la tige de remontoir et la carrure. Ce manchon semble autoriser un déplacement latéral de la tige par rapport à la carrure lors d'un choc mais les contraintes subies par la tige et par le mécanisme de remontage et de mise à l'heure restent élevées. De telles contraintes peuvent en outre apparaître, en dehors de tout choc, lorsque l'utilisateur exerce lui-même une pression latérale sur la couronne.We know from the document FR 2 463 437 a timepiece whose movement is held by an annular elastic damping support which comprises a radial projection defining a sealing sleeve interposed between the winding stem and the middle part. This sleeve seems to allow a lateral displacement of the rod with respect to the middle part during an impact but the stresses undergone by the stem and by the mechanism of reassembly and setting time remain high. Such constraints may also appear, apart from any shock, when the user exerts himself a lateral pressure on the crown.

Le document GB 1295347 divulgue une montre avec mouvement montre élastiquement à l'intérieur de la boîte.The document GB 1295347 discloses a watch with movement elastically shows inside the box.

La présente invention vise à proposer une pièce d'horlogerie dont le mouvement est tenu élastiquement et dans laquelle les contraintes sur la tige de remontoir ou tout autre organe de commande manuel sont réduites.The present invention aims at providing a timepiece whose movement is held elastically and in which the stresses on the winding stem or any other manual control member are reduced.

A cette fin, il est prévu une pièce d'horlogerie selon la revendication 1 annexée, c'est-à-dire une pièce d'horlogerie comprenant une boîte, un mouvement, un organe élastique amortisseur tenant le mouvement à l'intérieur de la boîte et un organe de commande manuel traversant une paroi de la boîte et connecté au mouvement, caractérisée en ce qu'elle comprend en outre un tube rigide traversant ladite paroi et solidaire du mouvement, tube dans lequel est engagé l'organe de commande manuel, et un manchon élastique amortisseur interposé entre le tube et ladite paroi.To this end, there is provided a timepiece according to claim 1 attached, that is to say a timepiece comprising a box, a movement, a resilient elastic member holding the movement inside the box and a manual control member passing through a wall of the box and connected to the movement, characterized in that it further comprises a rigid tube passing through said wall and secured to the movement, tube in which is engaged the manual control member, and a damping elastic sleeve interposed between the tube and said wall.

Ainsi, dans la présente invention, et à la différence des antériorités citées plus haut, l'organe de commande manuel est engagé dans un tube rigide. Ce tube n'est pas fixé rigidement dans la paroi de la boîte, comme les tubes de couronne usuels, mais est solidaire du mouvement. Ce tube est de plus entouré d'un manchon élastique amortisseur qui lui permet de se déplacer avec le mouvement, par rapport à la boîte, lors d'un choc ou lors d'une pression latérale exercée par l'utilisateur sur l'organe de commande manuel. De la sorte, l'organe de commande manuel ne subit sensiblement pas de contraintes de flexion.Thus, in the present invention, and unlike the prior art cited above, the manual control member is engaged in a rigid tube. This tube is not fixed rigidly in the wall of the box, like the usual crown tubes, but is integral with the movement. This tube is further surrounded by a shock absorbing elastic sleeve that allows it to move with the movement, with respect to the box, during an impact or during a lateral pressure exerted by the user on the body of manual control. In this way, the manual control member undergoes substantially no bending stresses.

Des modes de réalisation particuliers de la présente invention sont définis dans les revendications dépendantes annexées 2 à 10.Particular embodiments of the present invention are defined in the appended dependent claims 2 to 10.

D'autres caractéristiques et avantages de la présente invention apparaîtront à la lecture de la description détaillée suivante faite en référence aux dessins annexés dans lesquels :

  • la figure 1 est une vue en coupe axiale d'une pièce d'horlogerie selon l'invention ;
  • la figure 2 est une demi-vue en coupe axiale de la pièce d'horlogerie selon l'invention, prise dans un autre plan que celui de la figure 1 ;
  • la figure 3 est une vue en perspective éclatée d'une partie médiane de la pièce d'horlogerie selon l'invention.
Other features and advantages of the present invention will appear on reading the following detailed description given with reference to the accompanying drawings in which:
  • the figure 1 is an axial sectional view of a timepiece according to the invention;
  • the figure 2 is a half-view in axial section of the timepiece according to the invention, taken in a plane other than that of the figure 1 ;
  • the figure 3 is an exploded perspective view of a middle portion of the timepiece according to the invention.

En référence aux figures 1 à 3, une pièce d'horlogerie selon l'invention comprend une boîte 1 comprenant, de manière traditionnelle, une carrure 2, une lunette 3 dans laquelle est fixée une glace 4, et un fond 5. Dans l'exemple représenté, la lunette 3 est en deux parties, à savoir une partie interne 3a et une partie externe 3b fixées l'une à l'autre. Le fond 5 est lui aussi en deux parties, à savoir une partie centrale 5a constituée par une glace et une partie périphérique 5b dans laquelle est fixée la glace 5a. With reference to Figures 1 to 3 , a timepiece according to the invention comprises a box 1 comprising, traditionally, a middle part 2, a bezel 3 in which is fixed a glass 4, and a bottom 5. In the example shown, the bezel 3 is in two parts, namely an inner portion 3a and an outer portion 3b fixed to one another. The bottom 5 is also in two parts, namely a central portion 5a constituted by an ice and a peripheral portion 5b in which is fixed the ice 5a.

La face intérieure de la carrure 2 définit une gorge 6 dans laquelle est logé un anneau 7 réalisé dans une matière élastique telle que le caoutchouc naturel ou synthétique. L'anneau 7 a une face externe 8 à section concave pour augmenter son élasticité dans le plan radial et comprend sur sa face interne une saillie annulaire interrompue formant des languettes disjointes 9. Ces languettes 9 sont serrées entre un cercle supérieur 10 surmonté d'un réhaut 11 et qui s'appuie sur la face supérieure de ces languettes 9, et un cercle inférieur 12 qui s'appuie sur la face inférieure de ces languettes 9. La surface du cercle inférieur 12 qui s'appuie sur la face inférieure des languettes 9 est définie par un épaulement 13. Au dessus de cet épaulement 13, le cercle inférieur 12 définit une partie annulaire mince intérieure 14 et des oreilles radiales extérieures 15. Les oreilles 15 ont une position, une forme et une taille adaptées pour se placer entre les languettes 9. Les oreilles 15 sont traversées chacune par un perçage 16 qui traverse axialement la paroi du cercle inférieur 12 de part en part. Ces perçages 16 communiquent et sont alignés avec des perçages borgnes taraudés 17 formés dans le cercle supérieur 10. Une vis 18 est introduite dans chaque couple de perçages 16, 17 pour serrer les cercles 10, 12 entre eux et pour serrer les languettes 9 entre les cercles 10, 12. Le mouvement de la pièce d'horlogerie, représenté schématiquement par son volume hors tout 19, est disposé à l'intérieur de la structure annulaire formée par l'anneau élastique 7 et les cercles 10 et 12. Le mouvement 19 comporte un rebord 20 défini par sa platine. Le rebord 20 est en appui sur la partie annulaire mince 14 du cercle inférieur 12 et est maintenu sur cet appui 14 par des pattes 21 faisant saillie sur la face intérieure du cercle supérieur 10, pattes 21 qui s'appuient sur la face supérieure du mouvement 19, plus précisément de la platine.The inner face of the middle part 2 defines a groove 6 in which is housed a ring 7 made of an elastic material such as natural or synthetic rubber. The ring 7 has an outer face 8 of concave section to increase its elasticity in the radial plane and comprises on its inner face a broken annular projection forming disjoint tongues 9. These tongues 9 are clamped between an upper circle 10 surmounted by a flange 11 and which rests on the upper face of these tongues 9, and a lower circle 12 which rests on the underside of these tongues 9. The surface of the lower circle 12 which rests on the underside of the tongues 9 is defined by a shoulder 13. Above this shoulder 13, the lower circle 12 defines an inner thin annular portion 14 and outer radial ears 15. The lugs 15 have a position, a shape and a size adapted to be placed between the tongues 9. The lugs 15 are each traversed by a bore 16 which passes axially through the wall of the lower circle 12 from one side to the other. These bores 16 communicate and are aligned with threaded blind holes 17 formed in the upper circle 10. A screw 18 is inserted into each pair of bores 16, 17 to tighten the circles 10, 12 between them and to tighten the tongues 9 between them. circles 10, 12. The movement of the timepiece, shown schematically by its overall volume 19, is disposed within the annular structure formed by the elastic ring 7 and the circles 10 and 12. The movement 19 has a rim 20 defined by its plate. The flange 20 bears on the thin annular portion 14 of the lower circle 12 and is held on this support 14 by lugs 21 projecting on the inner face of the upper circle 10, lugs 21 which rest on the upper face of the movement 19, more precisely platinum.

Ainsi, le mouvement 19, le cercle supérieur 10 et le cercle inférieur 12 forment un ensemble rigide fixé à l'anneau élastique 7. Cet ensemble peut se déplacer par rapport à la boîte 1, notamment axialement et radialement, par déformation de l'anneau élastique 7. Comme on peut le voir sur la figure 1, un jeu suffisant est prévu entre cet ensemble 10, 12, 19 et la face intérieure de la carrure 2, ainsi qu'entre cet ensemble 10, 12, 19 et la glace 4 d'une part et le fond 5 d'autre part, pour autoriser un tel déplacement. En suspendant ainsi le mouvement 19 à l'intérieur de la boîte 1, l'anneau élastique 7 joue un rôle d'amortisseur de chocs protégeant le mouvement 19.Thus, the movement 19, the upper circle 10 and the lower circle 12 form a rigid assembly fixed to the elastic ring 7. This assembly can move relative to the box 1, in particular axially and radially, by deformation of the ring 7. As can be seen on the figure 1 , a game sufficient is provided between this assembly 10, 12, 19 and the inner face of the middle part 2, and between this assembly 10, 12, 19 and the ice cream 4 on the one hand and the bottom 5 on the other hand, to allow such a displacement. By thus suspending the movement 19 inside the box 1, the elastic ring 7 acts as a shock absorber protecting the movement 19.

La pièce d'horlogerie selon l'invention comprend en outre, de manière connue en soi, un organe de commande manuel 22 pouvant prendre plusieurs positions axiales et/ou tourner autour de son axe pour commander un mécanisme du mouvement 19. Cet organe de commande manuel 22 est typiquement une tige de remontage et de mise à l'heure 23 à l'extrémité de laquelle est fixée une couronne 24. Il est accessible depuis l'extérieur de la boîte 1 et traverse successivement la paroi de la carrure 2 et la paroi du cercle inférieur 12 pour pénétrer dans le mouvement 19. L'organe de commande manuel 22 est engagé dans un tube rigide 25 qui traverse la paroi de la carrure 2 et qui est fixé par son extrémité, par exemple par chassage ou vissage, dans la paroi du cercle inférieur 12. Le tube 25 est ainsi solidaire de l'ensemble formé par le mouvement 19 et les cercles 10 et 12. Le tube 25 est typiquement réalisé en métal, par exemple en acier ou en titane. Ce tube 25 est entouré d'un manchon 26 en matière élastique, par exemple en caoutchouc naturel ou synthétique. Plus précisément ce manchon 26 est comprimé entre le tube 25 et la paroi de l'ouverture 2a de la carrure 2 dans laquelle passent le tube 25 et l'organe de commande manuel 22, pour servir à la fois d'organe amortisseur et de joint d'étanchéité. De préférence, ce manchon 26 est lié à l'anneau élastique 7 en formant une saillie externe radiale de celui-ci, comme montré à la figure 3. De préférence encore, le manchon 26 est formé en une seule pièce avec l'anneau élastique 7.The timepiece according to the invention further comprises, in a manner known per se, a manual control member 22 that can take several axial positions and / or rotate about its axis to control a movement mechanism 19. This control member manual 22 is typically a winding and setting rod 23 at the end of which is fixed a ring 24. It is accessible from the outside of the box 1 and passes successively through the wall of the middle part 2 and the wall of the lower circle 12 to enter the movement 19. The manual control member 22 is engaged in a rigid tube 25 which passes through the wall of the middle part 2 and which is fixed at its end, for example by driving or screwing, in the wall of the lower circle 12. The tube 25 is thus integral with the assembly formed by the movement 19 and the circles 10 and 12. The tube 25 is typically made of metal, for example steel or titanium. This tube 25 is surrounded by a sleeve 26 of elastic material, for example natural or synthetic rubber. More precisely, this sleeve 26 is compressed between the tube 25 and the wall of the opening 2a of the middle part 2 in which the tube 25 and the manual control member 22 pass, to serve as both a damping member and a gasket. sealing. Preferably, this sleeve 26 is connected to the elastic ring 7 by forming a radial external projection thereof, as shown in FIG. figure 3 . More preferably, the sleeve 26 is formed in one piece with the elastic ring 7.

Ainsi, lorsqu'un choc se produit sur la pièce d'horlogerie, entraînant un déplacement de l'ensemble formé par le mouvement 19 et les cercles 10, 12, le tube 25 se déplace rigidement avec cet ensemble 19, 10, 12 et entraîne avec lui l'organe de commande manuel 22 qui ne subit donc pas de contraintes de flexion. De même, si l'utilisateur exerce une pression latérale sur l'organe de commande manuel 22, c'est-à-dire une pression de direction orthogonale à l'axe de l'organe 22, cette pression est transmise par l'organe de commande manuel 22 au tube 25, entraînant un déplacement rigide de l'ensemble 22, 25, 19, 10, 12 et évitant ainsi à l'organe de commande manuel 22 d'être soumis à des contraintes de flexion. On notera par ailleurs que le tube 25 permet d'éviter un contact direct de l'organe de commande manuel 22, typiquement fait en métal, avec la matière élastique du manchon 26, contact qui causerait des frictions importantes lors de la manipulation de l'organe de commande manuel 22.Thus, when a shock occurs on the timepiece, causing a displacement of the assembly formed by the movement 19 and the circles 10, 12, the tube 25 moves rigidly with this assembly 19, 10, 12 and causes with it the manual control member 22 which therefore does not undergo bending stresses. Similarly, if the user exerts a lateral pressure on the manual control member 22, that is to say a directional pressure orthogonal to the axis of the member 22, this pressure is transmitted by the organ manual control 22 to the tube 25, causing a rigid displacement of the assembly 22, 25, 19, 10, 12 and thus preventing the manual control member 22 to be subjected to bending stresses. Note also that the tube 25 avoids direct contact of the manual control member 22, typically made of metal, with the elastic material of the sleeve 26, which contact would cause significant friction when handling the manual control member 22.

L'étanchéité de la pièce d'horlogerie selon l'invention est assurée par un joint 27 entre la glace 4 et la lunette 3, un joint 28 entre la lunette 3 et la carrure 2, un joint 29 entre la carrure 2 et la partie périphérique 5b du fond 5, un joint 29a entre la partie périphérique 5b et la partie centrale 5a du fond 5, le manchon 26 entre le tube 25 et la carrure 2 et un ou des joints 30 entre l'organe de commande manuel 22 et la paroi intérieure du tube 25. Pour augmenter l'étanchéité au niveau de l'organe de commande manuel 22, une clé de compression 31 selon le brevet US 6 902 169 de la présente demanderesse peut être prévue avec des joints associés 32. L'anneau élastique amortisseur 7 n'assure pas de fonction d'étanchéité. Ainsi, il n'a pas besoin d'être contraint et peut donc remplir pleinement sa fonction d'amortisseur.The tightness of the timepiece according to the invention is provided by a seal 27 between the lens 4 and the bezel 3, a seal 28 between the bezel 3 and the middle part 2, a seal 29 between the middle part 2 and the part device 5b of the bottom 5, a seal 29a between the peripheral portion 5b and the central portion 5a of the bottom 5, the sleeve 26 between the tube 25 and the middle part 2 and one or more seals 30 between the manual control member 22 and the inner wall of the tube 25. To increase the seal at the manual control member 22, a compression key 31 according to the patent US 6,902,169 of the present applicant may be provided with associated seals 32. The damping elastic ring 7 does not provide a sealing function. Thus, it does not need to be constrained and can therefore fully fulfill its damper function.

On notera que la pièce d'horlogerie selon l'invention est facile à assembler et désassembler. Grâce à sa souplesse, la pièce monolithique définissant l'anneau 7 et le manchon 26 peut être facilement mise en place dans la gorge 6 de la face intérieure de la carrure 2, pour l'anneau 7, et dans l'ouverture traversante 2a de la carrure 2, pour le manchon 26. Ensuite on peut placer le cercle inférieur 12 contre les languettes 9, faire passer le tube 25 dans l'ouverture 2a et le fixer dans le cercle inférieur 12, mettre le mouvement 19 en appui sur le cercle inférieur 12, placer le cercle supérieur 10 en appui sur les languettes 9 et visser les cercles 10 et 12 l'un contre l'autre. Avec un tel assemblage, le mouvement 19 est tenu solidement et peut être facilement démonté et retiré de la boîte 1 en vue d'une réparation ou d'un entretien, par exemple.Note that the timepiece according to the invention is easy to assemble and disassemble. Thanks to its flexibility, the monolithic piece defining the ring 7 and the sleeve 26 can be easily put in place in the groove 6 of the inner face of the middle part 2, for the ring 7, and in the through opening 2a of the middle part 2, for the sleeve 26. Then we can place the lower circle 12 against the tongues 9, pass the tube 25 in the opening 2a and fix it in the lower circle 12, put the movement 19 in support on the circle lower 12, place the upper circle 10 on the tongues 9 and screw the circles 10 and 12 against each other. With such an assembly, the Motion 19 is held securely and can be easily disassembled and removed from box 1 for repair or maintenance, for example.

La présente invention a été décrite ci-dessus à titre d'exemple uniquement. Il va de soi que des modifications peuvent être faites sans sortir du cadre de l'invention revendiquée. Par exemple, au lieu d'être fixé dans la paroi du cercle inférieur 12, le tube 25 pourrait être fixé dans la platine du mouvement 19 ou dans la paroi du cercle supérieur 10. Les languettes d'appui 9 pourraient être remplacées par un anneau continu comportant des trous pour le passage des vis 18. De façon comparable, les pattes d'appui 21 pourraient être remplacées par un anneau continu. De plus, si la pièce d'horlogerie doit comporter un ou plusieurs organes de commande manuels supplémentaires, par exemple un bouton poussoir ou une autre couronne, l'anneau élastique 7 pourra comporter plusieurs manchons 26 sur sa périphérie et chaque organe de commande manuel pourra être engagé dans un tube rigide correspondant solidaire du mouvement et entouré d'un tel manchon. Enfin, la boîte 1 et la carrure 2 peuvent avoir des formes diverses autres que circulaire. Dans ce cas, l'anneau 7, le cercle supérieur 10 et le cercle inférieur 12 seront remplacés par des éléments ayant une forme mieux adaptée à la boîte, entourant le mouvement 19 comme les éléments 7, 10 et 12 et remplissant les fonctions décrites ci-dessus.The present invention has been described above by way of example only. It goes without saying that modifications can be made without departing from the scope of the claimed invention. For example, instead of being fixed in the wall of the lower circle 12, the tube 25 could be fixed in the plate of the movement 19 or in the wall of the upper circle 10. The support tongues 9 could be replaced by a ring Continuous having holes for the passage of the screws 18. Similarly, the support lugs 21 could be replaced by a continuous ring. In addition, if the timepiece must include one or more additional manual control members, for example a push button or another ring, the elastic ring 7 may comprise several sleeves 26 on its periphery and each manual control member may to be engaged in a corresponding rigid tube secured to the movement and surrounded by such a sleeve. Finally, the box 1 and the middle part 2 may have various shapes other than circular. In this case, the ring 7, the upper circle 10 and the lower circle 12 will be replaced by elements having a shape better adapted to the box, surrounding the movement 19 like the elements 7, 10 and 12 and fulfilling the functions described herein. -above.
