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.

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 un petit incrément pour ajuster la position angulaire relative de façon précise.The invention proposes to achieve a tight and secure assembly of trim components with an easy to adjust angular indexing and a small increment to adjust the relative angular position accurately.

Les figures illustrent l'exemple non limitatif de l'indexage angulaire d'un fond par rapport à une carrure de montre.The figures illustrate the nonlimiting example of the angular indexing of a bottom with respect to a middle watch.

Ainsi l'invention concerne un sous-ensemble d'habillage 100 pour montre, comportant au moins un joint d'étanchéité 9 entre un premier composant 1 et un deuxième composant 2, lesquels sont agencés pour être assemblés, notamment vissés, l'un sur l'autre en enfermant chaque joint d'étanchéité 9 pour constituer ensemble une structure étanche dans une position d'étanchéité de compression maximale d'au moins un joint d'étanchéité 9 selon une direction axiale D.Thus, the invention relates to a dressing subassembly 100 for a watch, comprising at least one seal 9 between a first component 1 and a second component 2, which are arranged to be assembled, in particular screwed, one on the other by enclosing each seal 9 to form together a sealed structure in a maximum compression sealing position of at least one seal 9 in an axial direction D.

Dans cette position d'étanchéité, le premier composant 1 et le deuxième composant 2 ne peuvent pas être rapprochés davantage l'un de l'autre, la position d'étanchéité correspondant à la compression maximale d'un joint 9 compatible avec ses propriétés physiques.In this sealing position, the first component 1 and the second component 2 can not be brought closer to one another, the sealing position corresponding to the maximum compression of a seal 9 compatible with its physical properties .

Selon l'invention, le premier composant 1 porte, directement ou indirectement, une première denture inclinée 11, qui est agencée pour coopérer avec une deuxième denture inclinée 21 antagoniste que porte, directement ou indirectement, le deuxième composant 2.According to the invention, the first component 1 carries, directly or indirectly, a first inclined toothing 11, which is arranged to cooperate with a second inclined toothing 21 which bears, directly or indirectly, the second component 2.

Et le premier composant 1, et/ou le deuxième composant 2, et/ou une deuxième bague 5 interposée entre le premier composant 1 et le deuxième composant 2, comporte au moins une zone déformable élastiquement sous l'action d'une rotation relative, autour de la direction axiale D, du premier composant 1 par rapport au deuxième composant 2. Cette rotation relative est imposée par un effort externe au sous-ensemble d'habillage 100, notamment par un couple appliqué à l'un des premier 1 et deuxième 2 composants par rapport à l'autre. La plage de déformation de cette au moins une zone déformable élastiquement est dimensionnée pour autoriser sa compression, lors de l'action d'un tel effort externe, avec une course suffisante pour permettre le franchissement des sommets de dents lors de la rotation relative d'une denture par rapport à l'autre. Cette plage de déformation permet encore sa détente élastique, lors du relâchement d'effort externe, pour permettre le retour en coopération complète des sommets de dents 110, 210, d'une des dentures avec les creux de dents 220, 120, de l'autre denture dans une nouvelle position angulaire relative.And the first component 1, and / or the second component 2, and / or a second ring 5 interposed between the first component 1 and the second component 2, comprises at least one elastically deformable zone under the action of a relative rotation, around the axial direction D, of the first component 1 relative to the second component 2. This relative rotation is imposed by an external force to the dressing subassembly 100, in particular by a torque applied to one of the first 1 and second 2 components compared to each other. The deformation range of this at least one elastically deformable zone is dimensioned to allow its compression, during the action of such an external force, with a sufficient stroke to allow the crossing of the tops of teeth during the relative rotation of a toothing relative to the other. This range of deformation still allows its elastic relaxation, during the release of external force, to allow the complete return co-operation of the tops of teeth 110, 210, of one of the teeth with the tooth recesses 220, 120, of the other teeth in a new relative angular position.

En somme l'application d'un effort externe, notamment d'un couple, permet le franchissement d'au moins un pas de celles des dentures dont le pas est le plus petit. De façon particulière, le pas de la première denture 11 est identique au pas de la deuxième denture 21, mais il pourrait aussi en être multiple ou sous-multiple entier. Chaque saut d'un tel pas correspond à un franchissement de sommet de dent. Grâce à la détente élastique après le saut, la nouvelle position atteinte est stable.In short, the application of an external force, especially a torque, allows the crossing of at least one pitch of those of the teeth whose pitch is the smallest. In a particular way, the pitch of the first toothing 11 is identical to the pitch of second gear 21, but it could also be multiple or submultiple integer. Each jump of such a step corresponds to a crossing of the tooth vertex. Thanks to the elastic relaxation after the jump, the new position reached is stable.

De préférence, les dentures inclinées 11 et 12 comportent chacune, tel qu'illustré sur les figures, une alternance de longues rampes 118, 218, et de faces abruptes 119, 219.Preferably, the inclined teeth 11 and 12 each comprise, as illustrated in the figures, an alternation of long ramps 118, 218, and steep faces 119, 219.

Cette disposition permet d'assurer un anti-retour du mécanisme, s'opposant à une désolidarisation accidentelle du premier composant 1 et du deuxième composant 2, dont la rotation relative est possible, pour effectuer un réglage angulaire relatif, dans un premier sens à condition de leur appliquer un effort, notamment un couple, supérieur à l'effort résistant constitué par la combinaison de l'effort de rappel élastique et de l'angle de denture de la zone déformable élastiquement, mais dont la rotation dans le sens opposé nécessite l'application d'un effort beaucoup plus important, en particulier dans le cas de faces abruptes 119, 219, qui sont droites comme sur la variante non limitative illustrée par les figures, ou même si on choisit des profils de dentures inclinées moins heurtées avec des premières rampes 118, 218 de pente plus faible que des rampes de sens contraire, en alternance, redescendant en creux de dents.This arrangement makes it possible to ensure a non-return mechanism, opposing an accidental disconnection of the first component 1 and the second component 2, whose relative rotation is possible, to perform a relative angular adjustment, in a first direction provided to apply a force, in particular a torque, greater than the resistant force constituted by the combination of the elastic return force and the tooth angle of the elastically deformable zone, but whose rotation in the opposite direction requires the application of a much greater force, especially in the case of steep faces 119, 219, which are straight as in the non-limiting variant illustrated by the figures, or even if one chooses profiles of inclined teeth less impacted with first ramps 118, 218 of lower slope than ramps of opposite direction, alternately, descending down hollow teeth.

Différentes variantes de mise en oeuvre sont donc possibles, notamment :

  • deux dentures antagonistes élastiques, par exemple en matière plastique ou en tôle étampée, de façon similaire à des rondelles éventail ;
  • deux dentures élastiques, dont l'une portée par une entretoise élastique ;
  • deux dentures élastiques, chacune portée par une entretoise élastique ;
  • une denture rigide et l'autre élastique;
  • une denture rigide et l'autre élastique, dont l'une portée par une entretoise élastique;
  • une denture rigide et l'autre élastique, chacune portée par une entretoise élastique;
  • deux dentures rigides, dont l'une portée par une entretoise élastique ;
  • deux dentures rigides, chacune portée par une entretoise élastique.
Different implementation variants are therefore possible, in particular:
  • two resilient antagonist teeth, for example of plastic or stamped sheet, similarly to fan washers;
  • two elastic teeth, one of which is carried by an elastic spacer;
  • two elastic teeth, each carried by an elastic spacer;
  • a rigid toothing and the other elastic;
  • a rigid toothing and the other elastic, one carried by an elastic spacer;
  • a rigid toothing and the other elastic, each carried by an elastic spacer;
  • two rigid toothings, one of which is carried by an elastic spacer;
  • two rigid teeth, each carried by an elastic spacer.

L'invention est illustrée, de façon non limitative, avec une seule de ces variantes, dans laquelle les deux dentures sont chacune indifféremment élastique ou rigide, et où une deuxième bague 5 assure la fonction d'élasticité pour le franchissement des sommets de dents et la détente élastique.The invention is illustrated, without limitation, with only one of these variants, in which the two teeth are each indifferently elastic or rigid, and wherein a second ring 5 provides the function of elasticity for crossing the tops of teeth and the elastic expansion.

Dans cette réalisation particulière, le premier composant 1 comporte une première entretoise 3 porteuse de la première denture inclinée 11, et le deuxième composant 2 comporte une deuxième entretoise 4 porteuse de la deuxième denture inclinée 21. Les alternatives inverses ne sont pas décrites ici, l'homme du métier n'aura pas de difficulté à permuter les fonctions des différents composants du sous-ensemble d'habillage 100 selon l'invention.In this particular embodiment, the first component 1 comprises a first spacer 3 carrying the first inclined toothing 11, and the second component 2 comprises a second spacer 4 carrying the second inclined toothing 21. The inverse alternatives are not described here, one skilled in the art will have no difficulty in permuting the functions of the various components of the covering subassembly 100 according to the invention.

Plus particulièrement, ce premier composant 1 comporte une première entretoise 3, et comporte un premier filetage 15, qui est agencé pour coopérer avec un premier taraudage complémentaire 35 que comporte cette première entretoise 3. Le premier composant 1 comporte encore une première surface d'appui de butée axiale 16, qui est agencée pour coopérer en appui de butée avec une première surface complémentaire d'appui de butée axiale 36 que comporte la première entretoise 3.More particularly, this first component 1 comprises a first spacer 3, and comprises a first thread 15, which is arranged to cooperate with a first complementary tapping 35 that comprises this first spacer 3. The first component 1 also comprises a first bearing surface axial stop 16, which is arranged to cooperate in abutment abutment with a first complementary abutment abutment surface 36 that includes the first spacer 3.

Plus particulièrement, le premier composant 1 comporte une première entretoise 3, et comporte une première bague 6 comportant la première denture inclinée 11, cette première entretoise 3 comportant des premiers moyens d'entraînement 38 agencés pour coopérer avec des premiers moyens d'entraînement complémentaires 68 que comporte la première bague 6.More particularly, the first component 1 comprises a first spacer 3, and comprises a first ring 6 comprising the first inclined toothing 11, this first spacer 3 comprising first drive means 38 arranged to cooperate with first complementary drive means 68 that includes the first ring 6.

Dans une réalisation particulière, la première entretoise 3 et la première bague 6 forment un composant monobloc.In a particular embodiment, the first spacer 3 and the first ring 6 form a single-piece component.

De façon similaire, dans une réalisation particulière le deuxième composant 2 comporte une deuxième entretoise 4, et comporte un deuxième taraudage 25, qui est agencé pour coopérer avec un deuxième filetage complémentaire 45 que comporte la deuxième entretoise 4. Ce deuxième composant 2 comporte une deuxième surface d'appui de butée axiale 26, qui est agencée pour coopérer en appui de butée avec une deuxième surface complémentaire d'appui de butée axiale 46 que comporte la deuxième entretoise 4.Similarly, in a particular embodiment the second component 2 comprises a second spacer 4, and comprises a second thread 25, which is arranged to cooperate with a second complementary thread 45 that includes the second spacer 4. This second component 2 comprises a second axial abutment bearing surface 26, which is arranged to cooperate in abutment abutment with a second complementary axial abutment bearing surface 46 that the second spacer 4 comprises.

Plus particulièrement, le sous-ensemble d'habillage 100 comporte une deuxième bague 5, qui est interposée entre le premier composant 1 et le deuxième composant 2, et qui comporte au moins une zone déformable élastiquement. Plus particulièrement, cette deuxième bague 5 est entièrement réalisée dans un matériau déformable élastiquement. Cette deuxième bague 5 est en appui par une surface de contact 57 qu'elle comporte, sur une surface de contact complémentaire 37 que comporte la première entretoise 3.More particularly, the covering subassembly 100 comprises a second ring 5, which is interposed between the first component 1 and the second component 2, and which comprises at least one elastically deformable zone. More particularly, this second ring 5 is entirely made of an elastically deformable material. This second ring 5 is supported by a surface of contact 57 that it comprises, on a complementary contact surface 37 that includes the first spacer 3.

Le fonctionnement est particulièrement simple. Il faut en premier visser le premier composant et le bloquer, et ensuite vient l'indexage angulaire.The operation is particularly simple. First you have to screw in the first component and block it, and then comes the angular indexing.

La deuxième entretoise 4 est fixée, de préférence par vissage comme dans la réalisation illustrée, au deuxième composant 2. La première entretoise 3 et la première bague 6 sont prisonnières, prises en sandwich entre la deuxième bague 5 et la deuxième entretoise 4. La deuxième bague 5 peut être en silicone ou autre matière élastique, elle est comprimée entre le deuxième composant 2 et la première entretoise 3. La première entretoise 3 est maintenue entre la deuxième bague 5, la première entretoise 3, et la deuxième entretoise 4.The second spacer 4 is fixed, preferably by screwing as in the embodiment illustrated, to the second component 2. The first spacer 3 and the first ring 6 are trapped, sandwiched between the second ring 5 and the second spacer 4. The second ring 5 may be silicone or other elastic material, it is compressed between the second component 2 and the first spacer 3. The first spacer 3 is held between the second ring 5, the first spacer 3, and the second spacer 4.

La première bague 6 et la deuxième entretoise 4 sont pourvues respectivement de la première denture 11 et de la deuxième denture 21. Le nombre de dents détermine la précision du positionnement de l'élément orientable, ici le premier composant 1, notamment un fond, si l'on considère que le deuxième composant 2, notamment une carrure, est fixe. Une réalisation avec 180 dents permet ainsi une précision de deux degrés.The first ring 6 and the second spacer 4 are respectively provided with the first toothing 11 and the second set of teeth 21. The number of teeth determines the positioning accuracy of the orientable element, here the first component 1, in particular a bottom, if it is considered that the second component 2, including a middle part, is fixed. An embodiment with 180 teeth allows a precision of two degrees.

La première denture 11 et la deuxième denture 21 permettent, par effet de cliquet, en raison de l'élasticité de la deuxième bague 5, à la première entretoise 3 et à la première bague 6 de tourner l'une par rapport à l'autre, dans un seul sens, le système est donc unidirectionnel.The first toothing 11 and the second toothing 21 allow, by ratchet effect, because of the elasticity of the second ring 5, the first spacer 3 and the first ring 6 to rotate relative to each other in one sense, the system is unidirectional.

Le premier composant 1 vient se visser dans la première entretoise 3. Une fois la première entretoise 3 en position de butée sur le premier composant 1, par coopération de butée de la première surface complémentaire d'appui de butée axiale 36 et de la première surface d'appui de butée axiale 16, les deux pièces deviennent solidaires, et le joint d'étanchéité 9 est plaqué et comprimé dans son logement 29 du deuxième composant 2 et sur la surface d'appui de joint 19 du premier composant. Les différentes coopérations de butée du mécanisme, entre le premier composant 1 et la première entretoise 3 d'une part, et entre le deuxième composant 2 et la deuxième entretoise 4 d'autre part, permettent entre autres de garantir un niveau maximal de compression de ce joint d'étanchéité 9.The first component 1 is screwed into the first spacer 3. Once the first spacer 3 in the abutment position on the first component 1, by abutment cooperation of the first complementary axial abutment bearing surface 36 and the first surface axial abutment support 16, the two parts become integral, and the seal 9 is pressed and compressed in its housing 29 of the second component 2 and on the joint bearing surface 19 of the first component. The various stops of the mechanism, between the first component 1 and the first spacer 3 on the one hand, and between the second component 2 and the second spacer 4, on the other hand, make it possible, among other things, to guarantee a maximum level of compression of this seal 9.

Si l'opérateur continue à appliquer un couple sur le premier composant 1 pour le faire tourner, le premier composant 1 et la première entretoise 3 et la première bague 6, formant un équipage solidaire, commencent à glisser sur les rampes faisant cliquets de la deuxième entretoise 4, ce qui permet un positionnement axial du premier composant 1.If the operator continues to apply a torque on the first component 1 to rotate, the first component 1 and the first spacer 3 and the first ring 6, forming a fixed crew, begin to slide on the ramps ratchets of the second spacer 4, which allows axial positioning of the first component 1.

Pour le démontage, il suffit de dévisser le premier composant 1. Grâce aux dentures de la première bague 6 et de la deuxième entretoise 4, celles-ci viennent se bloquer l'une contre l'autre, et deviennent solidaires du deuxième composant 2, et le premier composant 1 peut être dévissé.For disassembly, simply unscrew the first component 1. Thanks to the teeth of the first ring 6 and the second spacer 4, they come to lock against each other, and become integral with the second component 2, and the first component 1 can be unscrewed.

Dans la réalisation particulière illustrée par les figures 1 à 7, la première denture inclinée 11 et la deuxième denture inclinée 21 comportent des sommets de dents définissant un premier plan P1 et respectivement un deuxième plan P2 perpendiculaires à la direction axiale D.In the particular realization illustrated by the Figures 1 to 7 , the first inclined toothing 11 and the second inclined toothing 21 comprise tooth tops defining a first plane P1 and respectively a second plane P2 perpendicular to the axial direction D.

Dans une autre réalisation schématisée sur la figure 8, les composants comportant les dentures sont coaxiaux, et la première denture inclinée 11 et la deuxième denture inclinée 21 comportent des sommets de dents définissant un premier cylindre C1 et respectivement un deuxième cylindre C2 coaxiaux et parallèles à la direction axiale D.In another embodiment schematized on the figure 8 , the components comprising the teeth are coaxial, and the first inclined toothing 11 and the second inclined toothing 21 comprise toothing of teeth defining a first cylinder C1 and a second cylinder C2 coaxial and parallel to the axial direction D.

Dans une application particulière illustrée sur les figures 1 à 6, le premier composant 1 est un fond et le deuxième composant 2 est une carrure de montre. Naturellement la configuration inverse est elle aussi parfaitement réalisable.In a particular application illustrated on Figures 1 to 6 , the first component 1 is a bottom and the second component 2 is a middle watch. Naturally the reverse configuration is also perfectly feasible.

Dans une autre application, le premier composant 1 est une carrure et le deuxième composant 2 est un réhaut ou une lunette. Cette variante est intéressante pour des montres de plongée à lunette unidirectionnelle.In another application, the first component 1 is a middle and the second component 2 is a flange or bezel. This variant is interesting for diving watches with unidirectional bezel.

Dans une autre application encore, le premier composant 1 est une carrure ou un tube rapporté sur une carrure, et le deuxième composant 2 est une couronne.In yet another application, the first component 1 is a middle part or a tube attached to a middle part, and the second component 2 is a crown.

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

En somme, l'invention permet un ajustement angulaire précis entre deux composants d'un habillage de montre, ou encore d'un appareil scientifique assimilable à une montre par sa constitution d'habillage, la précision d'ajustement angulaire étant donnée par le plus petit pas des dentures inclinées que comporte le sous-ensemble d'habillage selon l'invention.In short, the invention allows a precise angular adjustment between two components of a watch covering, or a scientific apparatus comparable to a watch by its covering constitution, the angular adjustment accuracy being given by the most small pitch inclined teeth that includes the dressing subassembly according to the invention.

L'invention garantit un serrage parfait du joint d'étanchéité entre le premier et le deuxième composants.The invention ensures a perfect clamping of the seal between the first and second components.

L'invention s'oppose encore, à un démontage accidentel et involontaire de l'assemblage des deux composants, car sa conception nécessite l'application d'un effort beaucoup plus important au démontage qu'au montage.The invention is still opposed to accidental and unintentional disassembly of the assembly of the two components, because its design requires the application of a much greater effort to disassembly assembly.
