  • the general denomination of "dressing" sub-assembly is used here as well for a timepiece as for a jewel, even if this term is of current use in watchmaking only. It is understood that, in the case of jewelery, this subset may relate to the structure of the jewel, or elements reported on a basic structure, or any assembly of several elementary or pre-assembled components, or the entire jewel.

  • This joining of the first component 1 and the second component 10, by bayonet adjustment, especially around an axial direction D, is reversible, and allows their disassembly.
  • this disassembly requires on the part of an operator efforts similar to those exerted during assembly, this disassembly preferably requires the use of a tool special, cooperating for example with holes or peripheral notches, or the like, and can not be consecutive to clumsiness or exposure to particular external physical factors.

And any passage of such a notch 26 on a complementary relief 18 generates a resisting torque which tends to oppose the relative rotational movement between the first component 1 and the second component 10, at least one such notch 26 being arranged for the relative angular indexing between the first component 1 and the second component 10.
  • the invention relates to a subassembly of dressing 100 for a timepiece or watch, comprising at least one seal 9 between a first component 1 and a second component 10.

  • At least one such notch 26 is arranged for the relative angular indexing between the first component 1 and the second component 10. More particularly the pair formed by a particular notch 26 and a particular complementary relief 18 corresponds to the exercise of a maximum resistive force, and this particular torque corresponds to a preferred position of indexing and locking indexed position.

  • the minimum applied axial force necessarily corresponds to the sealing of the seal or seals 9.
  • the first notch 26 and the first complementary relief 18 constitute the housing 6 and the 29 for indexing angular position of the second component 10 relative to the first component 1. For example, three notches at 120 ° cooperate with reliefs also complementary to 120 °, the operator feels a single pass hard point when the three notches at 120 ° act simultaneously.
  • the subassembly 100 comprises a plurality of notches 26 and a plurality of complementary reliefs 18, relatively arranged relative to one another so that, at the beginning of the relative rotation, a single clearance-bossing pair is in cooperation, then, after a certain angle, two release-bossing pairs are in simultaneous cooperation, and so on, the cumulative peak torque peak increasing during each hard point crossing, to reach, at the indexing angle, the value Max.

  • the seal exists as soon as the bayonet is set, and the mechanism according to the invention is arranged so that, as in the previous case of a single bump, the sealing of the seal (s) 9 is made safe. ensured from the passage of this first bump, since then no loosening can occur without voluntary action of an operator.
  • the figure 11 illustrates such an example, and superimposes the torque profile obtained with a particular variant of the invention, in full line, corresponding to the passage of three successive hard points, also called bumps, before the immobilization in the indexing position to the angle ⁇ M, with, by way of comparison, the increase in torque in the last degrees of closure of a conventional traditional face of the prior art (which may in particular require an angular amplitude of the order of two turns), in broken lines .
  • the only resistance to rotation are the mechanical friction forces due in particular to the axial forces generated by the compression of a seal at the end of the stroke, and to the elastic deformation of the components present during the definitive mechanical blocking.
  • the angular value ⁇ V corresponding to the maximum screwing with a pair ⁇ V corresponds to the end of a torque growth curve, whose slope becomes extremely steep in the vicinity of this value ⁇ V: which means that a subset screw which is then subjected to a large force may be unscrewed, without any guard to prevent a total unscrewing, or loss of sealing, since the torque required for unscrewing is then decreasing, and the energy to be provided for the looser than in the case of the invention.

It is still possible to mix these last two variants, everything is possible, the machining to be made is not very complex.
  • the invention requires, during the assembly, the successive crossing, in a kind of ramp, of several bumps of increasing resistance torque, but also the disassembly, since, since the final indexed position ⁇ M, in particular on a mechanical stop (which is however not necessary in the context of the invention), any application of a sudden effort is reflected in the worst case, by crossing a single bump, without total disassembly, with a visual shift, and especially without loss of sealing or risk of pollution of the interior of the watch.
  • the operator must successively cross three thresholds, visible optically because of the offset, before having a leakage loss.
  • each notch is identical, and its passage opposes the same resistant torque.
  • the coefficient multiplier of resistant torque from one notch to the other, can in particular be between 1.2 and 2.2.
  • the invention is advantageous because it is perfectly compatible with horological dimensions, while having a capacity of a high resistance force, which can reach several Nm, for example in the case of a third component of at least partially amorphous metallic material. Even with more common materials for the manufacture of technical rings, POM, polyurethane or similar, and axial and radial dimensions of a few tenths of a millimeter, the resistant torque easily exceeds one N.m.
  • the disassembly of the mechanism according to the invention requires the maintenance of the application of a possible effort of accidental origin during a large angular stroke, from 7 to 8 ° for the crossing of a single bump in the illustrated example, the security still being ensured if several bumps succeed one another, whereas, in screwed solution of the prior art, the dismantling is consumed in an angular stroke of the order of 2 ° only, and therefore the loss of tightness also.
  • the angular indexing can be guaranteed by a limit stop 28 stroke. But, preferably, it is the third component 20 which fills, de facto, the stop function, by the exercise of a particularly high resistant torque. Such a mechanical stop is therefore not absolutely necessary.
  • the invention thus makes it possible to prevent any unexpected and involuntary disassembly of the subassembly 100, for example under the effect of vibrations, of successive expansion cycles, by an unfortunate use of the user, or the like.

Arrière-plan de l'inventionBackground of the invention

L'habillage des montres et appareils similaires obéit à de nombreuses contraintes, en particulier d'étanchéité, de robustesse, d'aspect, et doit être réalisé de façon à prévenir tout démontage involontaire se traduisant irrémédiablement par une intervention d'après-vente pour échange de joints, nettoyage, lubrification, voire réparation.The cladding of watches and similar devices obeys many constraints, in particular sealing, robustness, appearance, and must be realized in order to prevent any unintentional disassembly resulting irreparably by an after-sales intervention for exchange of seals, cleaning, lubrication, even repair.

Certains composants d'habillage ou de commande doivent, encore, être indexés angulairement les uns par rapport aux autres, pour des repérages de position de référence d'origine, de repos, ou d'actionnement, ou encore pour faciliter la lecture d'indications ou de graduations, ou pour assurer la continuité de surfaces gauches et/ou de décors. Cet indexage angulaire est souvent délicat à bien réaliser, en combinaison avec un bon serrage des composants et avec une étanchéité parfaite des joints.Some dressing or control components must, again, be indexed angularly with respect to each other, for reference positions of origin reference, rest, or actuation, or to facilitate the reading of indications or graduations, or to ensure the continuity of left surfaces and / or decorations. This angular indexing is often difficult to achieve, in combination with a good tightening of the components and with a perfect sealing of the joints.

Résumé de l'inventionSummary of the invention

Description détaillée des modes de réalisation préférésDetailed Description of the Preferred Embodiments

L'invention se propose de réaliser un assemblage étanche et sécurisé de composants d'habillage avec un indexage angulaire facile à régler, et dans une position garantie, et ceci avec un nombre minimal de composants, et des coûts de fabrication modérés.The invention proposes to achieve a tight and secure assembly of cladding components with easy to adjust angular indexing, and in a guaranteed position, and this with a minimum number of components, and moderate manufacturing costs.

Les figures 1 à 10 illustrent l'exemple non limitatif de l'indexage angulaire d'un fond par rapport à une carrure de montre.The Figures 1 to 10 illustrate the nonlimiting example of the angular indexing of a background relative to a watchband.

L'invention concerne un sous-ensemble d'habillage 100 pour une pièce d'horlogerie, et plus particulièrement pour une montre, ou pour un bijou, comportant un premier composant 1 comportant des rebords 2 saillant d'une première jupe 6 alternés avec des premiers dégagements, et un deuxième composant 10 comportant des ailes 12 saillant d'une deuxième jupe 11 alternées avec des deuxièmes dégagements 13.The invention relates to a covering subassembly 100 for a timepiece, and more particularly for a watch, or for a jewel, comprising a first component 1 comprising flanges 2 projecting from a first skirt 6 alternated with first clearances, and a second component 10 having wings 12 projecting from a second skirt 11 alternated with second clearances 13.

On utilise ici la dénomination générale de sous-ensemble « d'habillage » aussi bien pour une pièce d'horlogerie que pour un bijou, même si ce terme est d'emploi courant en horlogerie seulement. On comprend que, dans le cas de la bijouterie, ce sous-ensemble peut concerner la structure du bijou, ou des éléments rapportés sur une structure de base, ou tout assemblage de plusieurs composants élémentaires ou pré-assemblés, voire le bijou tout entier.The general denomination of "dressing" sub-assembly is used here as well for a timepiece as for a jewel, even if this term is of current use in watchmaking only. It is understood that, in the case of jewelery, this subset may relate to the structure of the jewel, or elements reported on a basic structure, or any assembly of several elementary or pre-assembled components, or the entire jewel.

Ce sous-ensemble d'habillage 100 est agencé pour passer d'une première position démontée d'insertion, à une deuxième position assemblée et verrouillée.This dressing subassembly 100 is arranged to pass from a first disassembled insertion position to a second assembled and locked position.

Dans la première position démontée d'insertion, le premier composant 1 et le deuxième composant 10 ont l'un par rapport à l'autre une première orientation angulaire.In the first disassembled insertion position, the first component 1 and the second component 10 have a first angular orientation relative to each other.

Dans une variante particulière, non limitative, comportant des moyens de répulsion agencés au niveau de l'interface entre le premier composant 1 et le deuxième composant 10, ces derniers tendent à être maintenus à distance l'un de l'autre par des moyens de répulsion, lesquels comportent des moyens de répulsion magnétique et/ou au moins un élément élastique et/ou au moins un joint d'étanchéité 9. Le passage de la première position démontée d'insertion à la deuxième position assemblée et verrouillée est effectué sous l'action d'efforts exercés par un opérateur: un effort axial pour surmonter l'effort résistant des moyens de répulsion et mettre au contact le premier composant 1 et le deuxième composant 10, et un couple pour les amener dans une position d'indexation angulaire.In a particular, non-limiting variant, comprising repulsion means arranged at the interface between the first component 1 and the second component 10, the latter tend to be kept at a distance from each other by means of repulsion, which comprise magnetic repulsion means and / or at least one resilient element and / or at least one seal 9. The passage from the first disassembled insertion position to the second assembled and locked position is performed under the following conditions: action of forces exerted by an operator: an axial force to overcome the resisting force of the repulsion means and to put the first component 1 and the second component 10 in contact with one another and a torque to bring them into an angular indexing position .

Dans la deuxième position assemblée et verrouillée, le premier composant 1 et le deuxième composant 10 ont l'un par rapport à l'autre une deuxième orientation angulaire différente de la première orientation angulaire. Dans la variante particulière comportant des moyens de répulsion, le premier composant 1 et le deuxième composant 10 sont maintenus axialement à l'encontre de l'effort résistant exercé par ces moyens de répulsion, par l'effet d'un ajustement à baïonnette, réalisé par l'application des efforts axiaux et de couple imprimés par l'opérateur, entre au moins deux rebords 2 et au moins deux ailes 12.In the second assembled and locked position, the first component 1 and the second component 10 have relative to each other a second angular orientation different from the first angular orientation. In the particular variant comprising repulsion means, the first component 1 and the second component 10 are held axially against the resisting force exerted by these repulsion means, by the effect of a bayonet adjustment, realized by applying the axial and torque forces printed by the operator, between at least two edges 2 and at least two wings 12.

Cette solidarisation du premier composant 1 et du deuxième composant 10, par ajustement à baïonnette, notamment autour d'une direction axiale D, est réversible, et autorise leur démontage. De façon propre à l'invention et en rupture avec l'art antérieur, ce démontage nécessite de la part d'un opérateur des efforts similaires à ceux exercés lors de l'assemblage, ce démontage nécessite de préférence l'utilisation d'un outil spécial, coopérant par exemple avec des trous ou des encoches périphériques, ou similaire, et ne peut être consécutif à une maladresse ni à l'exposition à des facteurs physiques externes particuliers.This joining of the first component 1 and the second component 10, by bayonet adjustment, especially around an axial direction D, is reversible, and allows their disassembly. In a manner peculiar to the invention and in rupture with the prior art, this disassembly requires on the part of an operator efforts similar to those exerted during assembly, this disassembly preferably requires the use of a tool special, cooperating for example with holes or peripheral notches, or the like, and can not be consecutive to clumsiness or exposure to particular external physical factors.

Selon l'invention, ce sous-ensemble d'habillage 100 comporte au moins un troisième composant 20, qui est agencé pour être intercalé radialement, ou respectivement axialement, entre le premier composant 1 et le deuxième composant 10 et fixe en rotation par rapport à l'un d'entre eux, et qui comporte au moins une zone 50 déformable élastiquement radialement, ou respectivement axialement.According to the invention, this covering subassembly 100 comprises at least a third component 20, which is arranged to be interposed radially, or respectively axially, between the first component 1 and the second component 10 and fixed in rotation relative to one of them, and which comprises at least one zone 50 deformable elastically radially, or respectively axially.

Ce troisième composant 20 est inséré ponctuellement, ou bien au niveau de surfaces étendues, il peut prendre différentes formes, notamment une forme de secteur annulaire ou de bague comme dans la variante non limitative illustrée.This third component 20 is inserted punctually, or at the level of extended surfaces, it can take different forms, including a form of annular sector or ring as in the non-limiting variant illustrated.

Cette zone déformable 50 est agencée pour opposer un couple résistant de moment variable à tout couple tangentiel relatif entre le premier composant 1 et ledit deuxième composant 10. Cette zone déformable 50 comporte au moins un cran 26, qui est agencé pour coopérer avec au moins un relief complémentaire 18 que comporte celui des composants 1, 10, par rapport auquel le troisième composant 20 est libre en rotation. Et tout passage d'un tel cran 26 sur un relief complémentaire 18 génère un couple résistant qui tend à s'opposer au mouvement relatif de rotation entre le premier composant 1 et le deuxième composant 10, au moins un tel cran 26 étant agencé pour l'indexage angulaire relatif entre le premier composant 1 et le deuxième composant 10.This deformable zone 50 is arranged to oppose a resisting torque of variable moment to any relative tangential torque between the first component 1 and said second component 10. This deformable zone 50 comprises at least one notch 26, which is arranged to cooperate with at least one complementary relief 18 that comprises that of the components 1, 10, with respect to which the third component 20 is free in rotation. And any passage of such a notch 26 on a complementary relief 18 generates a resisting torque which tends to oppose the relative rotational movement between the first component 1 and the second component 10, at least one such notch 26 being arranged for the relative angular indexing between the first component 1 and the second component 10.

Plus particulièrement, dans une variante particulière non limitative comportant des moyens de répulsion, et illustrée par les figures, l'invention concerne un sous-ensemble d'habillage 100 pour pièce d'horlogerie ou montre, comportant au moins un joint d'étanchéité 9 entre un premier composant 1 et un deuxième composant 10. Dans cette variante particulière, le premier composant 1 comporte des rebords 2 saillant radialement vers l'intérieur d'une première jupe 6, qui sont alternés avec des premiers dégagements 3. Le deuxième composant 10 comporte des ailes 12 saillant radialement vers l'extérieur d'une deuxième jupe 11, qui sont alternées avec des deuxièmes dégagements 13. Ce sous-ensemble d'habillage 100 est alors agencé pour passer d'une position démontée à une position assemblée en compression du joint d'étanchéité 9, par la solidarisation réversible du premier composant 1 et du deuxième composant 10, par un ajustement à baïonnette entre au moins deux rebords 2 et au moins deux ailes 12, dans un mouvement de rotation relatif autour d'une direction axiale D. Si la compression axiale du joint d'étanchéité 9 est la plus classique, l'invention permet aussi sans difficulté un assemblage avec compression radiale d'un tel joint.More particularly, in a particular non-limiting variant comprising means of repulsion, and illustrated by the figures, the invention relates to a subassembly of dressing 100 for a timepiece or watch, comprising at least one seal 9 between a first component 1 and a second component 10. In this particular embodiment, the first component 1 comprises flanges 2 protruding radially inwardly of a first skirt 6, which are alternated with first clearances 3. The second component 10 has wings 12 protruding radially outwardly of a second skirt 11, which are alternated with second clearances 13. This subassembly dressing 100 is then arranged to move from a disassembled position to an assembled position in compression of the seal 9, by the reversible joining of the first component 1 and the second component 10, by a bayonet fit between at least two flanges 2 and at least two flanges 12, in a relative rotational movement around an axial direction D. If the axial compression of the seal 9 is the most conventional, the invention also makes it easy to assemble with radial compression of such a seal.

On comprend que l'invention est illustrée ici dans une variante particulière, avec des rebords et des ailes saillant radialement. L'invention est aussi applicable à d'autres variantes où les configurations axiale et radiale sont inversées.It is understood that the invention is illustrated here in a particular variant, with flanges and radially projecting flanges. The invention is also applicable to other variants where the axial and radial configurations are reversed.

Le sous-ensemble d'habillage 100 comporte ainsi au moins un troisième composant 20, qui est agencé pour être intercalé radialement dans la variante illustrée par les figures, entre le premier composant 1 et le deuxième composant 10. Ce troisième composant 20 est fixe en rotation par rapport au premier composant 1 ou au deuxième composant 10. Le troisième composant 20 qui comporte au moins une zone 50 déformable élastiquement, notamment radialement dans la variante des figures. Cette zone déformable 50 est agencée pour opposer un couple résistant de moment variable à tout couple tangentiel relatif entre le premier composant 1 et le deuxième composant 10.The dressing subassembly 100 thus comprises at least a third component 20, which is arranged to be inserted radially in the variant illustrated by the figures, between the first component 1 and the second component 10. This third component 20 is fixed in rotation relative to the first component 1 or the second component 10. The third component 20 which comprises at least one zone 50 elastically deformable, in particular radially in the variant of the figures. This deformable zone 50 is arranged to oppose a resistant torque of variable moment to any relative tangential pair between the first component 1 and the second component 10.

Ce troisième composant 20 présente l'effet élastique escompté, rapporté ou inséré dans le premier composant 1 ou dans le deuxième composant 10. De façon préférée mais non limitative, il est au moins partiellement annulaire, en secteur annulaire, ou encore en forme de bague fermée comme sur les figures, ou de bague fendue, ou similaire.This third component 20 has the desired elastic effect, reported or inserted in the first component 1 or in the second component 10. Preferably, but not limited to, it is at least partially annular, ring-shaped, or ring-shaped closed as in the figures, or split ring, or the like.

De préférence, la zone déformable 50 comporte au moins un cran 26, qui est agencé pour coopérer avec au moins un relief complémentaire 18 que comporte celui des composants 1, 10, par rapport auquel le troisième composant 20 est libre en rotation. L'agencement relatif des composants du sous-ensemble 100 est tel que tout passage d'un tel cran 26 sur un tel relief complémentaire 18 génère un couple résistant, qui tend à s'opposer au mouvement relatif de rotation entre le premier composant 1 et le deuxième composant 10. Au moins un tel cran 26 est agencé pour l'indexage angulaire relatif entre le premier composant 1 et le deuxième composant 10. Plus particulièrement le couple formé par un cran 26 particulier et un relief complémentaire 18 particulier correspond à l'exercice d'un effort résistant maximal, et ce couple particulier correspond à une position préférentielle d'indexage et de blocage en position indexée.Preferably, the deformable zone 50 comprises at least one notch 26, which is arranged to cooperate with at least one complementary relief 18 that comprises that of the components 1, 10, with respect to which the third component 20 is free to rotate. The relative arrangement of the components of the sub-assembly 100 is such that any passage of such a notch 26 on such a complementary relief 18 generates a resisting torque, which tends to oppose the relative rotational movement between the first component 1 and the second component 10. At least one such notch 26 is arranged for the relative angular indexing between the first component 1 and the second component 10. More particularly the pair formed by a particular notch 26 and a particular complementary relief 18 corresponds to the exercise of a maximum resistive force, and this particular torque corresponds to a preferred position of indexing and locking indexed position.

Plus particulièrement, ce troisième composant 20 est une bague fermée, sensiblement torique.More particularly, this third component 20 is a closed, substantially toroidal ring.

Dans une réalisation particulière non limitative, le troisième composant 20 est réalisé complètement en matériau élastique.In a particular non-limiting embodiment, the third component 20 is made completely of elastic material.

Plus particulièrement, le premier composant 1 comporte au moins un logement 6 d'arrêt d'un ergot anti-rotation 29 que comporte le troisième composant 20.More particularly, the first component 1 comprises at least one housing 6 for stopping an anti-rotation pin 29 that comprises the third component 20.

Naturellement, la configuration peut être inversée, avec un logement d'arrêt présent dans le deuxième composant 10.Naturally, the configuration can be reversed, with a stop housing present in the second component 10.

Plus particulièrement, la zone déformable 50 comporte une pluralité de crans 26, qui sont agencés pour opposer une résistance successive à un relief complémentaire 18. Plus particulièrement encore, dans une même telle zone déformable 50, les crans 26 successifs sont agencés pour opposer une résistance croissante à un relief complémentaire 18, lors de la croissance de l'angle relatif entre le premier composant 1 et le deuxième composant 10.More particularly, the deformable zone 50 comprises a plurality of notches 26, which are arranged to oppose a successive resistance to a complementary relief 18. More particularly, in the same deformable zone 50, the successive notches 26 are arranged to oppose a resistance increasing to a complementary relief 18, during the growth of the relative angle between the first component 1 and the second component 10.

On comprend que l'effort résistant peut être d'autant plus important que le nombre de crans 26 et de reliefs complémentaires 18 en coopération est élevé. Il est donc possible de jouer sur le nombre de crans successifs, et/ou sur la hauteur de chaque cran, ou, plus exactement, l'effort résistant au passage de chaque cran.It is understood that the resistant force can be all the more important as the number of notches 26 and complementary reliefs 18 in cooperation is high. It is therefore possible to play on the number of successive notches, and / or on the height of each notch, or, more exactly, the force resistant to the passage of each notch.

Lors de l'assemblage, l'utilisateur imprime un couple progressif pour imprimer la rotation relative entre le premier composant 1 et le deuxième composant 10. Après l'insertion du deuxième composant 10 dans le premier composant 1 en enfermant chaque joint 9, dans la position de la figure 2, et la mise en appui des ailes 12 et des rebords 2, lors de cette rotation relative, l'opérateur effectuant l'assemblage du sous-ensemble 100 rencontre une première résistance lors de la mise en coopération d'un premier cran 26 avec un premier relief complémentaire 18. Le couple résistant progresse lors de la rotation relative.During assembly, the user prints a progressive torque to print the relative rotation between the first component 1 and the second component 10. After the insertion of the second component 10 into the first component 1 enclosing each seal 9, in the position of the figure 2 , and the support of the wings 12 and flanges 2, during this relative rotation, the operator performing the assembly of the subassembly 100 encounters a first resistance when a first notch 26 is brought into cooperation with a first complementary relief 18. The resisting torque progresses during the relative rotation.

Dans un premier cas de figure, le premier cran 26 et le premier relief complémentaire 18 sont uniques (ou bien sont chacun remplacé par une pluralité de tels couples, de profil et de résistance identique, et disposés en périphérie du profil de façon à interférer en même temps: ce qui revient à un cran résultant unique, et un relief unique ; cette possibilité de duplication de profils en phase n'est pas exposée plus en détail, et est applicable à toute variante de l'invention). Dans ce premier cas, l'effort axial appliqué minimal correspond nécessairement à la mise en étanchéité du ou des joints d'étanchéité 9. Et cette position unique de coopération, le premier cran 26 et le premier relief complémentaire 18 constituent le logement 6 et l'ergot 29 pour l'indexage en position angulaire du deuxième composant 10 par rapport au premier composant 1. Par exemple, trois crans à 120° coopèrent avec des reliefs complémentaires eux aussi à 120°, l'opérateur ressent un seul passage de point dur lorsque les trois crans à 120° agissent simultanément.In a first case, the first notch 26 and the first complementary relief 18 are unique (or are each replaced by a plurality of such couples, of identical profile and resistance, and arranged at the periphery of the profile so as to interfere with same time: which amounts to a single resulting notch, and a unique relief, this possibility of duplication of profiles in phase is not exposed in more detail, and is applicable to any variant of the invention). In this first case, the minimum applied axial force necessarily corresponds to the sealing of the seal or seals 9. And this unique position of cooperation, the first notch 26 and the first complementary relief 18 constitute the housing 6 and the 29 for indexing angular position of the second component 10 relative to the first component 1. For example, three notches at 120 ° cooperate with reliefs also complementary to 120 °, the operator feels a single pass hard point when the three notches at 120 ° act simultaneously.

Dans un deuxième cas de figure, le sous-ensemble 100 comporte plusieurs crans 26 et plusieurs reliefs complémentaires 18, agencés relativement les uns par rapport aux autres pour que, au début de la rotation relative, un seul couple dégagement-bossage soit en coopération, puis, après un certain angle, deux couples dégagement-bossage soient en coopération simultanée, et ainsi de suite, le sommet de couple résistant cumulé augmentant lors de chaque passage de point dur, pour atteindre, à l'angle d'indexage, la valeur maximale. L'opérateur rencontre ainsi une sensation de résistance croissante.In a second case, the subassembly 100 comprises a plurality of notches 26 and a plurality of complementary reliefs 18, relatively arranged relative to one another so that, at the beginning of the relative rotation, a single clearance-bossing pair is in cooperation, then, after a certain angle, two release-bossing pairs are in simultaneous cooperation, and so on, the cumulative peak torque peak increasing during each hard point crossing, to reach, at the indexing angle, the value Max. The operator thus encounters a feeling of increasing resistance.

L'étanchéité existe dès la mise en baïonnette, et le mécanisme selon l'invention est agencé pour que, comme dans le cas précédent d'une bosse unique, la mise en sécurité de l'étanchéité du ou des joints d'étanchéité 9 soit assurée dès le passage de cette première bosse, puisqu'alors aucun desserrage ne peut se produire sans action volontaire d'un opérateur.The seal exists as soon as the bayonet is set, and the mechanism according to the invention is arranged so that, as in the previous case of a single bump, the sealing of the seal (s) 9 is made safe. ensured from the passage of this first bump, since then no loosening can occur without voluntary action of an operator.

Dans la pratique, de très bons résultats sont obtenus avec au moins deux, et de préférence trois, voire quatre, bosses successives, de préférence sans dépasser cinq, de façon à procurer une course angulaire élémentaire suffisante pour le passage de chaque bosse. Un bon exemple pratique comporte trois ensembles en phase, correspondant chacun à trois bosses.In practice, very good results are obtained with at least two, and preferably three or even four, successive bumps, preferably not exceeding five, so as to provide an elementary angular stroke sufficient for the passage of each bump. A good practical example has three sets in phase, each corresponding to three bumps.

La figure 11 illustre un tel exemple , et superpose le profil de couple obtenu avec une variante particulière de l'invention, en trait plein, correspondant au passage de trois points durs successifs, aussi appelés bosses, avant l'immobilisation en position d'indexage à l'angle θM, avec, à titre de comparaison la montée de couple dans les derniers degrés de fermeture d'un visage traditionnel usuel de l'art antérieur (qui peut notamment nécessiter une amplitude angulaire de l'ordre de deux tours), en trait interrompu. Dans un tel vissage traditionnel, les seules résistances à la rotation sont les forces de frottement mécanique dues notamment aux efforts axiaux engendrés par la compression d'un joint d'étanchéité en fin de course, et à la déformation élastique des composants en présence lors du blocage mécanique définitif. On y voit que l'atteinte du niveau de couple garantissant l'étanchéité du ou des joints 9 n'est atteinte que pour un angle relatif beaucoup plus important, et qu'il n'y a pas d'effet de seuil au démontage, la perte d'étanchéité se faisant dans le cas du dévissage sans rencontrer d'effort résistant contrairement à l'invention.The figure 11 illustrates such an example, and superimposes the torque profile obtained with a particular variant of the invention, in full line, corresponding to the passage of three successive hard points, also called bumps, before the immobilization in the indexing position to the angle θM, with, by way of comparison, the increase in torque in the last degrees of closure of a conventional traditional face of the prior art (which may in particular require an angular amplitude of the order of two turns), in broken lines . In such a traditional screwing, the only resistance to rotation are the mechanical friction forces due in particular to the axial forces generated by the compression of a seal at the end of the stroke, and to the elastic deformation of the components present during the definitive mechanical blocking. It can be seen that the attainment of the torque level guaranteeing the tightness of the seal (s) 9 is only reached for a much larger relative angle, and that there is no threshold effect at dismantling, the loss of tightness occurring in the case of unscrewing without encountering a resistant force contrary to the invention.

De plus, la valeur angulaire θV correspondant au vissage maximal avec un couple γV correspond à la fin d'une courbe de croissance de couple, dont la pente devient extrêmement raide au voisinage de cette valeur θV : ce qui signifie qu'un sous-ensemble vissé qui est alors soumis à un effort important risque de se dévisser, sans aucun garde-fou pour empêcher un dévissage total, ni la perte d'étanchéité, puisque le couple nécessaire au dévissage est alors dégressif, et l'énergie à fournir pour le dévissage plus faible que dans le cas de l'invention.Moreover, the angular value θV corresponding to the maximum screwing with a pair γV corresponds to the end of a torque growth curve, whose slope becomes extremely steep in the vicinity of this value θV: which means that a subset screw which is then subjected to a large force may be unscrewed, without any guard to prevent a total unscrewing, or loss of sealing, since the torque required for unscrewing is then decreasing, and the energy to be provided for the looser than in the case of the invention.

Dans une autre variante encore, non illustrée, une même bosse coopère successivement avec plusieurs dégagements, qui peuvent être chacun de même profondeur dans une réalisation particulière, créant alors une valeur d'effort résistant fixe, et qu'il faut passer à plusieurs reprises pour arriver en position fermée et indexée. Il est, encore, possible de panacher ces deux dernières variantes, tout est possible, les usinages à réaliser étant peu complexes.In yet another variant, not illustrated, a same boss cooperates successively with several clearances, which may each be of the same depth in a particular embodiment, then creating a fixed resistance force value, and which must be repeatedly passed for arrive in closed and indexed position. It is still possible to mix these last two variants, everything is possible, the machining to be made is not very complex.

Au contraire, l'invention nécessite, lors de l'assemblage, le franchissement successif, dans une sorte de rampe, de plusieurs bosses de couple de résistance croissante, mais aussi au démontage, car, depuis la position finale indexée θM, notamment sur une éventuelle butée mécanique (qui n'est toutefois pas nécessaire dans le cadre de l'invention), toute application d'un effort soudain se traduit, dans le pire des cas, par le franchissement d'une seule bosse, sans désassemblage total, avec un décalage visuel, et surtout sans perte d'étanchéité ni risque de pollution de l'intérieur de la montre. Dans l'exemple illustré l'opérateur doit franchir successivement trois seuils, visible optiquement en raison du décalage, avant d'avoir une perte d'étanchéité.On the contrary, the invention requires, during the assembly, the successive crossing, in a kind of ramp, of several bumps of increasing resistance torque, but also the disassembly, since, since the final indexed position θM, in particular on a mechanical stop (which is however not necessary in the context of the invention), any application of a sudden effort is reflected in the worst case, by crossing a single bump, without total disassembly, with a visual shift, and especially without loss of sealing or risk of pollution of the interior of the watch. In the illustrated example, the operator must successively cross three thresholds, visible optically because of the offset, before having a leakage loss.

Dans un cas particulier, chaque cran est identique, et son passage oppose un même couple résistant.In a particular case, each notch is identical, and its passage opposes the same resistant torque.

Dans une variante avantageuse, plusieurs crans se succèdent, et l'opérateur doit appliquer un couple croissant, comme dans l'exemple des trois crans de la figure 11. Le coefficient multiplicateur de couple résistant, d'un cran à l'autre, peut notamment être compris entre 1,2 et 2,2.In an advantageous variant, several notches succeed one another, and the operator must apply a growing torque, as in the example of the three notches of the figure 11 . The coefficient multiplier of resistant torque, from one notch to the other, can in particular be between 1.2 and 2.2.

L'invention est avantageuse car parfaitement compatible avec des dimensions horlogères, tout en ayant une capacité d'un effort résistant élevé, qui peut atteindre plusieurs N.m, par exemple dans le cas d'un troisième composant en matériau métallique au moins partiellement amorphe. Même avec des matériaux plus courants pour la fabrication de bagues techniques, POM, polyuréthane ou similaire, et des dimensions axiales et radiales de quelques dixièmes de millimètre, le couple résistant excède facilement un N.m.The invention is advantageous because it is perfectly compatible with horological dimensions, while having a capacity of a high resistance force, which can reach several Nm, for example in the case of a third component of at least partially amorphous metallic material. Even with more common materials for the manufacture of technical rings, POM, polyurethane or similar, and axial and radial dimensions of a few tenths of a millimeter, the resistant torque easily exceeds one N.m.

D'ailleurs, dans le cas où la pièce d'horlogerie ou de bijouterie est soumise à des contraintes particulières de grande ampleur, le démontage du mécanisme selon l'invention nécessite le maintien de l'application d'un éventuel effort d'origine accidentelle pendant une course angulaire importante, de 7 à 8° pour le franchissement d'une seule bosse dans l'exemple illustré, la sécurité restant encore assurée si plusieurs bosses se succèdent, alors que, en solution vissée de l'art antérieur, le démontage est consommé dans une course angulaire de l'ordre de 2° seulement, et donc la perte d'étanchéité également.Moreover, in the case where the timepiece or jewelery is subjected to particular constraints of great magnitude, the disassembly of the mechanism according to the invention requires the maintenance of the application of a possible effort of accidental origin during a large angular stroke, from 7 to 8 ° for the crossing of a single bump in the illustrated example, the security still being ensured if several bumps succeed one another, whereas, in screwed solution of the prior art, the dismantling is consumed in an angular stroke of the order of 2 ° only, and therefore the loss of tightness also.

Dans une variante, l'indexage angulaire peut être garanti par une butée 28 de limitation de course. Mais, de préférence, c'est le troisième composant 20 qui remplit, de facto, la fonction de butée, par l'exercice d'un couple résistant particulièrement élevé. Une telle butée mécanique n'est de ce fait pas absolument nécessaire.Alternatively, the angular indexing can be guaranteed by a limit stop 28 stroke. But, preferably, it is the third component 20 which fills, de facto, the stop function, by the exercise of a particularly high resistant torque. Such a mechanical stop is therefore not absolutely necessary.

L'invention permet, ainsi, de prévenir tout démontage inopiné et involontaire du sous-ensemble 100, par exemple sous l'effet de vibrations, de cycles de dilatation successifs, par une utilisation malencontreuse de l'utilisateur, ou autre.The invention thus makes it possible to prevent any unexpected and involuntary disassembly of the subassembly 100, for example under the effect of vibrations, of successive expansion cycles, by an unfortunate use of the user, or the like.

De façon préférée, le démontage nécessite un outil spécial non commercialisé, ce qui assure l'exécution de la maintenance par du personnel d'après-vente possédant les qualifications requises.Preferably, the disassembly requires a special non-commercial tool, which ensures the execution of maintenance by aftersales staff having the required qualifications.

Les figures illustrent différentes variantes nullement limitatives.The figures illustrate various non-limiting variants.

Les figures 1 à 7 illustrent une première variante, où le troisième composant 20 est une bague 24 maintenue en appui sur une surface plane 5 que comportent les rebords 2 du premier composant 1 constitué par une carrure, et les prolongements de ces rebords 2. Cette bague 24 est bien solidarisée angulairement avec le premier composant 1, par des ergots 29 d'anti-rotation dont les contours extérieurs sont logés de façon complémentaire dans des logements 6 de la carrure 1. Les trois composants en présence comportent ici chacun trois fois les mêmes contours, également répartis à 120°. Le deuxième composant 10 est un fond, manipulé par un opérateur, de préférence à l'aide d'un outil spécial. Au-dessus de la jupe 11 de ce fond 10, le rebord 12 est contourné de façon à pouvoir déformer progressivement la bague 24 lors de sa rotation (dans le sens anti-horaire pour ces figures). Ce rebord 12 comporte en particulier une rampe 18 qui fait fléchir les surfaces antagonistes de la bague 24. Cette rampe est ici suivie d'un dégagement 17 qui autorise le mouvement de crans saillants 27, 28, que comporte intérieurement la bague 24, dont l'un 27 est sensiblement parallèle à un dégagement 25 que comporte la bague 24 sur sa face extérieure, au niveau d'une telle zone déformable 50, tandis que l'autre 28 fait face à une portée d'appui sensiblement cylindrique de la bague 24. Un creux 26 sépare ces crans saillants 27 et 28 sur la face intérieure de la bague 24.The Figures 1 to 7 illustrate a first variant, wherein the third component 20 is a ring 24 held in abutment on a flat surface 5 that comprise the flanges 2 of the first component 1 constituted by a middle part, and the extensions of these flanges 2. This ring 24 is firmly connected angularly with the first component 1, by anti-rotation pins 29 whose outer contours are housed in complementary manner in housings 6 of the caseband 1. The three components in the present here each comprise three times the same contours, evenly distributed. at 120 °. The second component 10 is a bottom, manipulated by an operator, preferably with the aid of a special tool. Above the skirt 11 of the bottom 10, the flange 12 is contoured so as to be able to gradually deform the ring 24 during its rotation (in the counterclockwise direction for these figures). This flange 12 comprises in particular a ramp 18 which bends the antagonistic surfaces of the ring 24. This ramp is here followed by a clearance 17 which allows the movement of notches projecting 27, 28, which internally comprises the ring 24, which a 27 is substantially parallel to a clearance 25 that includes the ring 24 on its outer face, at such a deformable zone 50, while the other 28 faces a substantially cylindrical bearing surface of the ring 24 A hollow 26 separates these projecting notches 27 and 28 on the inner face of the ring 24.

Les figures 8 à 10 illustrent une deuxième variante, assez similaire à la précédente, comportant aussi une répétition à 120°, le fond 10 comporte ici, après la rampe 18 et séparés par des reliefs intermédiaires, trois dégagements 171, 172, 173, qui sont agencés pour coopérer successivement avec des bossages 271, 272, 273 de la bague. Le repère angulaire 19 du fond 10 permet de repérer la position angulaire relative de la carrure 1 et du fond 10 : 50° sur la figure 8, 30° sur la figure 9, 0° sur la figure 10. On comprend que, lors de la progression angulaire, tout d'abord un seul couple dégagement-bossage171/ 273 oppose un premier effort résistant lors du passage du cran qu'il constitue; puis, un peu plus loin, deux couples dégagement-bossage171/272 et 172/273 opposent ensemble un deuxième effort résistant supérieur au premier ; puis, encore plus loin, trois couples dégagement-bossage171/2171, 172/272 et 173/273 opposent ensemble un troisième effort résistant supérieur au deuxième. On a ainsi un moyen très simple permettant d'opposer un effort résistant croissant en fonction de l'angle de rotation. La figure 11 montre bien le passage de chacun de ces crans, et la croissance du niveau de couple maximal associé.The Figures 8 to 10 illustrate a second variant, quite similar to the previous one, also comprising a repetition at 120 °, the bottom 10 comprises here, after the ramp 18 and separated by intermediate reliefs, three clearances 171, 172, 173, which are arranged to cooperate successively with bosses 271, 272, 273 of the ring. The angular mark 19 of the bottom 10 makes it possible to locate the relative angular position of the middle part 1 and the bottom 10: 50 ° on the figure 8 , 30 ° on the figure 9 , 0 ° on the figure 10 . It will be understood that, during the angular progression, first of all a single relief-bossing pair 171/273 opposes a first resisting force during the passage of the notch it constitutes; then, a little further, two clearance-bossing pairs 171/272 and 172/273 together oppose a second resisting force greater than the first; then, even further, three couples clearance-bossage171 / 2171, 172/272 and 173/273 together oppose a third resisting force greater than the second. There is thus a very simple way to oppose a growing resistant force depending on the angle of rotation. The figure 11 shows the passage of each of these notches, and the growth of the maximum torque level associated.

L'invention se prête bien aux cas où le sous-ensemble 100 comporte des composants 1 et 10 réalisés dans des matériaux différents, avec des coefficients de dilatation différents, ou encore des matières fragiles, ou dures (céramique, saphir), qui n'autorisent pas des modes de fixation standard. Citons parmi des configurations classiques l'assemblage d'une carrure en or avec un fond saphir, ou encore une boîte entièrement en céramique, une combinaison métal-céramique, ou similaires.The invention is well suited to cases where the subassembly 100 comprises components 1 and 10 made of different materials, with different coefficients of expansion, or fragile or hard materials (ceramic, sapphire), which do not allow standard fastening methods. Among conventional configurations include assembling a gold case with a sapphire caseback, or a box entirely ceramic, a metal-ceramic combination, or the like.

Le troisième composant 20 est de préférence une bague, qui peut être réalisée en différents matériaux , notamment POM, polyuréthane, matière à base polymère, ou élastomère, alliage métallique au moins partiellement amorphe, le matériau choisi déterminant le couple de serrage maximal, ainsi une bague en alliage amorphe autorise un couple de serrage d'environ 3.2 N.m, similaire à celui usuel d'un fond vissé sur une carrure, pour un joint 9 de même taille. Cette bague peut encore être réalisée en métal amorphe, inox, CuBe, « Liquidmetal© », voire être bi-matériaux, par exemple avec une âme en matériau plastique avec des inserts surmoulés, métalliques, ou en céramique, ou autre. L'intérêt d'une telle bague, de préférence dans un matériau élastique polymère ou similaire, est sa facilité de logement dans un volume dont l'espace libre est très limité, où il est impossible d'implanter en toute sécurité un élément métallique susceptible de casser.The third component 20 is preferably a ring, which may be made of different materials, in particular POM, polyurethane, polymer-based material, or elastomer, at least partially amorphous metal alloy, the chosen material determining the maximum tightening torque, thus a amorphous alloy ring allows a tightening torque of about 3.2 Nm, similar to the usual one of a bottom screwed on a middle, for a joint 9 of the same size. This ring can also be made of amorphous metal, stainless steel, CuBe, "Liquidmetal ©", or even bi-materials, for example with a plastic core with molded inserts, metal, or ceramic, or other. The advantage of such a ring, preferably in a polymeric elastic material or the like, is its ease of housing in a volume whose free space is very limited, where it is impossible to implement safely a metal element susceptible to break.

Naturellement, le matériau du troisième composant 20 peut aussi être plus complexe, notamment sous la forme d'une matière de type élastomère chargée avec des fibres techniques telles que « Kevlar® » ou similaire, ou avec un additif anti-usure tel que polytétrafluoroéthylène dit PTFE, ou autre.Naturally, the material of the third component 20 may also be more complex, especially in the form of an elastomer type material loaded with technical fibers such as "Kevlar®" or the like, or with an antiwear additive such as polytetrafluoroethylene said PTFE, or other.

Un avantage important de l'invention est de nécessiter ni perçage ni taraudage, mais uniquement des usinages simples réalisables avec une certaine facilité, évitant ainsi toute salissure ou pollution de la montre, et autorisant un coût modéré.An important advantage of the invention is to require neither drilling nor tapping, but only simple machining achievable with a certain ease, thus avoiding any soiling or pollution of the watch, and allowing a moderate cost.

Plus particulièrement, et tel que visible sur les figures 1 à 10 et 12, le premier composant 1 est une carrure et le deuxième composant 10 est un fond. Dans une variante particulière, la présence d'au moins un joint d'étanchéité est requise. Dans une variante non illustrée, le premier composant 1 est un fond et le deuxième composant 10 est une pièce d'aspect, telle qu'un médaillon, ou similaire, rapportée sur ce fond, auquel cas un joint entre eux n'est pas nécessaire, et la présence d'un ressort pouvant parfaitement suffire dans une variante comportant des moyens de répulsion.More particularly, and as visible on the Figures 1 to 10 and 12 , the first component 1 is a middle and the second component 10 is a bottom. In a particular variant, the presence of at least one seal is required. In a variant not shown, the first component 1 is a bottom and the second component 10 is a part of appearance, such as a medallion, or the like, attached to this bottom, in which case a seal between them is not necessary, and the presence of a spring that can perfectly suffice in a variant comprising repulsion means.

On note, à ce propos, que l'invention peut être mise en oeuvre sans de tels moyens de répulsion, notamment pour des applications d'habillage ou similaire.It should be noted, in this connection, that the invention can be implemented without such repulsion means, in particular for cladding applications or the like.

Dans une autre application, le premier composant 1 est une carrure et le deuxième composant 10 est un réhaut ou une lunette, tel que visible sur la figure 13. Ce cas convient bien à une variante dans laquelle un premier composant et un deuxième composant tendent à être éloignés l'un de l'autre, par répulsion magnétique ou encore par un élément élastique tel qu'un jonc, c'est-à-dire une bague mince, non nécessairement fermée, ou plus particulièrement un jonc comportant des segments analogues à un rochet pour n'autoriser facilement qu'une manoeuvre unidirectionnelle, comme dans le cas particulier d'utilisation de l'invention pour une lunette unidirectionnelle. Un tel jonc peut être filiforme, de section sensiblement ronde, ou bien à section rectangulaire, ou autre. Ou, encore le troisième composant 20 constitue tout simplement lui-même les moyens de répulsion, ce qui réduit sensiblement le nombre de composants tout en assurant très bien le maintien requis.In another application, the first component 1 is a middle part and the second component 10 is a flange or bezel, as visible on the figure 13 . This case is well suited to a variant in which a first component and a second component tend to be separated from each other, by magnetic repulsion or by an elastic element such as a rod, that is to say a thin ring, not necessarily closed, or more particularly a rod comprising segments similar to a ratchet to allow easy unidirectional maneuver, as in the particular case of use of the invention for a unidirectional bezel. Such a ring may be filiform, of substantially round section, or rectangular section, or other. Or, again the third component 20 is simply repulsion means itself, which substantially reduces the number of components while ensuring very good maintenance required.

Dans une autre application encore, le premier composant 1 est une carrure ou un tube rapporté sur une carrure, et le deuxième composant 10 est une couronne, tel que visible sur la figure 14. Dans une variante, le deuxième composant 10 est une tige de couronne ou un poussoir. Dans ces cas de figure aussi, la présence d'au moins un joint d'étanchéité est obligatoire.In yet another application, the first component 1 is a middle part or a tube attached to a middle part, and the second component 10 is a crown, as visible on the figure 14 . In a variant, the second component 10 is a crown rod or a pusher. In these cases too, the presence of at least one seal is mandatory.

L'invention est apte à de nombreuses applications en horlogerie, par exemple pour une valve hélium sur une montre de plongée, ou encore pour des composants d'habillage tels qu'un bracelet, une boucle, un fermoir, ou autre. Il en est de même en bijouterie, pour effectuer la fermeture de boutons de manchette, de boucles d'oreilles, ou encore pour fixer des pierreries ou des éléments décorés conçus de manière amovible.The invention is suitable for many applications in watchmaking, for example for a helium valve on a diving watch, or for dressing components such as a bracelet, a buckle, a clasp, or other. It is the same in jewelry, for closing cufflinks, earrings, or for securing precious stones or decorated elements removably designed.

L'invention concerne encore une pièce d'horlogerie ou montre 1000 comportant un tel sous-ensemble d'habillage 100.The invention also relates to a timepiece or watch 1000 comprising such a dressing subassembly 100.

L'invention concerne encore un bijou comportant un tel sous-ensemble 100.The invention also relates to a jewel comprising such a subassembly 100.

En somme, l'invention permet de disposer d'un sous-ensemble à assemblage à baïonnette, avec une bague de maintien montée sur un premier composant, notamment une bague sensiblement torique. Cette bague peut aussi être ouverte, par exemple avec une fente comme un circlips ou similaire, pour faciliter le montage. Lors de la rotation relative du deuxième composant par rapport au premier composant, des encoches du deuxième composant viennent se bloquer avec des encoches de la bague. Cette conception est peu encombrante, elle assure le maintien de l'étanchéité de la montre, qu'elle protège contre tout démontage accidentel.In sum, the invention makes it possible to have a subassembly with a bayonet connection, with a retaining ring mounted on a first component, in particular a substantially toroidal ring. This ring can also be opened, for example with a slot like a circlip or the like, to facilitate assembly. During the relative rotation of the second component relative to the first component, notches of the second component come to lock with notches of the ring. This design is compact, it maintains the seal of the watch, it protects against accidental disassembly.

L'invention permet d'assurer l'orientation parfaite d'un composant maintenu bloqué dans sa position de service.The invention makes it possible to ensure the perfect orientation of a locked component in its operating position.

Quand le sous-ensemble selon l'invention remplit une fonction de fermeture d'un fond ou similaire, il procure de nombreux avantages :

  • à partir d'une première position angulaire relative, entre le premier composant et le deuxième composant, où la fonction d'étanchéité est assurée, par exemple dès que la compression d'un joint d'étanchéité est effectuée, il existe, dans le mécanisme selon l'invention, un domaine élargi de valeurs angulaires relatives entre ce premier composant et ce deuxième composant, dans lequel l'étanchéité reste garantie, par exemple de plusieurs dizaines de degrés, ce qui est important en comparaison avec par exemple un fond vissé standard dans le cas d'un sous-ensemble carrure-fond, où un dévissage de quelques degrés seulement (moins de dix degrés) entraîne la perte d'étanchéité et la nécessité d'une remise en propreté et d'une nouvelle de revendication, alors que selon l'invention ce n'est qu'après le passage du tout dernier cran lors du démontage que la perte d'étanchéité devient possible si l'on poursuit la rotation;
  • une fermeture par succession de crans qui présente un couple de fermeture du fond largement dimensionné, à la fois suffisant et acceptable pour un tel montage, grâce en particulier à la multiplication du nombre de bosses réparties sur la circonférence, avec, pour l'opérateur, une sensation de vissage par étapes d'augmentation du couple de fermeture jusqu'à la position désirée, réputée être la position fermée, qui est aussi bien perceptible ;
  • une sécurité d'ouverture, qui est augmentée par deux facteurs : la nécessité pour l'opérateur de fournir une énergie positive importante pour passer un cran ; et le passage successif de plusieurs crans préalable à toute perte d'étanchéité.
When the subassembly according to the invention performs a function of closing a bottom or the like, it provides many advantages:
  • from a first relative angular position, between the first component and the second component, where the sealing function is ensured, for example as soon as the compression of a seal is performed, there is, in the mechanism according to the invention, an enlarged range of relative angular values between this first component and this second component, in which the sealing remains guaranteed, for example by several tens of degrees, which is important in comparison with, for example, a standard screwed bottom in the case of a middle-to-back subassembly, where a unscrewing of only a few degrees (less than ten degrees) results in the loss of watertightness and the need for a cleanup and a new claim, then that according to the invention it is only after the passage of the very last notch during disassembly that the loss of tightness becomes possible if one continues the rotation;
  • a succession of notches closure which has a large dimensionally closed bottom closure torque, both sufficient and acceptable for such an assembly, thanks in particular to the multiplication of the number of bumps distributed over the circumference, with, for the operator, a tightening sensation in steps of increasing the closing torque to the desired position, deemed to be the closed position, which is also noticeable;
  • an opening security, which is increased by two factors: the need for the operator to provide significant positive energy to pass a notch; and the successive passage of several notches prior to any leakage.

L'invention autorise, encore, la mise en coopération de composants antagonistes réalisés en matières de différentes natures, sans contrainte de dilatation frottement, élasticité, ou autre, sans nécessiter d'élément de fixation extérieur tel que vis ou similaire, sans pas de vis ni usinage risquant de fragiliser des matières particulières telles que céramiques, saphir, et similaires. Elle présente une très bonne résistance à un dévissage accidentel ou même volontaire par vibration ou du type Chapuis-chocs. L'invention permet aussi d'assurer l'interchangeabilité des composants, et, par conséquent, une personnalisation accrue des montres ou des bijoux des utilisateurs.The invention also authorizes the cooperation of antagonistic components made of different materials, without expansion stress friction, elasticity, or other, without requiring external fastening element such as screw or the like, without screws nor machining may weaken particular materials such as ceramics, sapphire, and the like. It has a very good resistance to accidental or even voluntary unwinding by vibration or Chapuis-choc type. The invention also makes it possible to ensure the interchangeability of the components, and, consequently, an increased personalization of the watches or jewels of the users.

Cette invention est applicable aussi bien à des montres ou bijoux réalisés en matériaux précieux qu'à des réalisations de grande série comportant des composants de faible coût unitaire, notamment en matière plastique ou similaire.This invention is applicable both to watches or jewelery made of precious materials that large series of achievements comprising low unit cost components, including plastic or similar.

L'invention se prête bien aux cas où le sous-ensemble 100 comporte des composants 1 et 10 réalisés dans des matériaux différents, avec des coefficients de dilatation différents, ou encore des matières fragiles, ou dures (céramique, saphir, pierres précieuses, gemmes, camées), qui n'autorisent pas des modes de fixation standard. Citons parmi des configurations classiques l'assemblage d'une carrure en or avec un fond saphir, ou encore une boîte entièrement en céramique, une combinaison métal-céramique, ou similaires.
