Detailed Description of the Preferred Embodiments
L'invention concerne le domaine de l'horlogerie, et est plus particulièrement illustrée pour le domaine des ensembles réglants comportant un balancier.  The invention relates to the field of watchmaking, and is more particularly illustrated for the field of control assemblies comprising a balance.
L'invention concerne un ensemble d'horlogerie 30 comportant au moins deux mobiles 20 antagonistes 20A, 20B, couplés l'un à l'autre et coopérant par contact l'un avec l'autre au niveau de surfaces périphériques de contact 200, respectivement 200A, 200B, tel que visible sur la figure 5.  The invention relates to a timepiece assembly 30 comprising at least two opposing movable members 20A, 20B, coupled to each other and cooperating by contact with each other at peripheral contact surfaces 200, respectively 200A, 200B, as visible in Figure 5.
Selon l'invention, chaque surface périphérique de contact 200 de chaque mobile 20 couplé dans un tel ensemble 30 est la surface périphérique d'une peau 210 en matière plastique.  According to the invention, each peripheral contact surface 200 of each mobile 20 coupled in such an assembly 30 is the peripheral surface of a plastic skin 210.
De préférence, la matière plastique utilisée pour le surmoulage cette peau 210 est une matière à faible coefficient de frottement inférieur à 0,15, et de préférence compris entre 0,07 et 0,15, choisie pour créer un couple de frottement minimal avec un composant antagoniste.  Preferably, the plastic material used for overmolding this skin 210 is a material with a low coefficient of friction of less than 0.15, and preferably between 0.07 and 0.15, chosen to create a minimal friction torque with a antagonistic component.
Dans une variante préférée, les peaux 210 portant les surfaces périphériques de contact 200 des mobiles 20 couplés deux à deux au sein d'un même ensemble 30 sont réalisées dans la même matière plastique.  In a preferred embodiment, the skins 210 bearing the peripheral contact surfaces 200 of the mobiles 20 coupled in pairs within the same assembly 30 are made of the same plastic material.
Dans une variante préférée, la peau 210 portant la surface périphérique de contact 200 d'au moins un de deux mobiles 20 antagonistes appairés au sein d'un tel ensemble 30 est réalisée en surmoulage sur un noyau de base 250.  In a preferred variant, the skin 210 carrying the peripheral contact surface 200 of at least one of two paired opposing moters within such an assembly 30 is made by overmolding on a base core 250.
Dans une variante particulière, la peau 210 portant la surface périphérique de contact 200 de chacun des deux mobiles 20 antagonistes appairés au sein d'un tel ensemble 30 est réalisée en surmoulage sur un noyau de base 250.  In a particular variant, the skin 210 carrying the peripheral contact surface 200 of each of the pair of paired opposing mobiles 20 within such an assembly 30 is made by overmoulding on a base core 250.
Avantageusement, au moins une telle peau 210 est surmoulée sur un noyau de base 250 réalisé dans un matériau thermiquement neutre ou en silicium, ou oxyde de silicium, ou en quartz, ou similaire.  Advantageously, at least one such skin 210 is overmolded on a base core 250 made of a thermally neutral material or silicon, or silicon oxide, or quartz, or the like.
Avantageusement, dans le cas de surfaces de contact 200 se développant parallèlement à l'axe de pivotement de deux mobiles 20A et 20B pivotant autour d'axes parallèles DA et DB, la section radiale de matière plastique périphérique des peaux 210 de ces deux mobiles 20 est égale.  Advantageously, in the case of contact surfaces 200 developing parallel to the pivot axis of two mobiles 20A and 20B pivoting about parallel axes DA and DB, the radial section of peripheral plastic material of the skins 210 of these two mobiles 20 is equal.
Les figures 3 et 4 illustrent un autre cas de figure, où la coopération entre les mobiles 20 se fait dans un plan perpendiculaire aux deux axes de pivotement parallèles DA, DB, des deux mobiles 20 d'un même ensemble 30. Dans ce cas il est préférable d'équilibrer les sections de matière plastique périphérique, mesurées dans un plan perpendiculaire au point de contact et parallèle aux axes de pivotement de ces deux mobiles 20. FIGS. 3 and 4 illustrate another case in which the cooperation between the mobiles 20 is in a plane perpendicular to the two parallel pivoting axes DA, DB, of the two mobiles 20 of the same assembly 30. In this case, is better to balance the sections of peripheral plastic material, measured in a plane perpendicular to the point of contact and parallel to the pivot axes of these two mobiles 20.
L'invention concerne en particulier des mobiles 20 de mécanisme d'échappement.  In particular, the invention relates to escapement mechanism mobiles.
Dans une réalisation particulière illustrée sur les figures 1 et 2, un premier mobile 20 est un balancier d'horlogerie 1 surmoulé sur un arbre de balancier 2.  In a particular embodiment illustrated in FIGS. 1 and 2, a first mobile 20 is a clock spring 1 overmolded on a balance shaft 2.
Selon l'invention, ce balancier 1 surmoulé comporte un petit plateau 4 et une cheville de plateau 5 en matière plastique surmoulés ensemble sur l'arbre 2.  According to the invention, this overmolded pendulum 1 comprises a small plate 4 and a plateau pin 5 of plastic material overmolded together on the shaft 2.
De façon avantageuse, l'arbre 2 comporte un flasque de rigidification 6 sur lequel est surmoulé le petit plateau 4. Différents modes de réalisation sont possibles : le flasque 6 est, ou bien un composant séparé enfilé sur l'arbre 2, et de préférence immobilisé sur celui-ci par chassage, collage, soudage, brasage, ou autre procédé convenable, ou bien un épaulement saillant constitutif de l'arbre 2.  Advantageously, the shaft 2 comprises a stiffening flange 6 on which is molded the small plate 4. Various embodiments are possible: the flange 6 is, or a separate component threaded onto the shaft 2, and preferably immobilized on it by driving, gluing, welding, soldering, or other suitable method, or a protruding shoulder constituting the shaft 2.
Dans un premier mode de réalisation, le flasque 6 constitue une surface d'appui pour une serge 7 chassée sur l'arbre 2.  In a first embodiment, the flange 6 constitutes a bearing surface for a serge 7 driven on the shaft 2.
Dans un deuxième mode de réalisation, le flasque 6 constitue une armature d'appui pour une serge 7 surmoulée sur l'arbre 2. Dans ce deuxième mode, le balancier 1 peut être réalisé selon une variante dans laquelle il comporte une serge 7 surmoulée, ensemble avec le petit plateau 4 et avec la cheville de plateau 5, sur l'arbre 2 et sur le flasque 6. Dans d'autres variantes, le surmoulage peut être conduit en plusieurs étapes.  In a second embodiment, the flange 6 constitutes a support frame for a serge 7 overmolded on the shaft 2. In this second mode, the balance 1 can be made according to a variant in which it comprises a serge 7 overmoulded, together with the small plate 4 and with the plate pin 5, on the shaft 2 and on the flange 6. In other variants, the overmolding can be conducted in several steps.
De façon avantageuse, la cheville de plateau 5 est saillante radialement par rapport à un corps 8 prolongeant le petit plateau 4 selon la direction axiale du balancier 1 .  Advantageously, the plate pin 5 is projecting radially with respect to a body 8 extending the small plate 4 in the axial direction of the rocker 1.
De préférence, le petit plateau 4 est cylindrique et comporte une encoche de plateau 9 périphérique. Avantageusement, le corps 8 est également cylindrique, de même diamètre que le petit plateau 4, et la cheville de plateau 5 est portée par un bras radial par rapport au corps 8 et aligné sur l'encoche de plateau 9.  Preferably, the small plate 4 is cylindrical and has a peripheral plate notch 9. Advantageously, the body 8 is also cylindrical, of the same diameter as the small plate 4, and the plate pin 5 is carried by a radial arm relative to the body 8 and aligned with the plate notch 9.
Dans cette version préférée où le petit plateau 4 comporte une encoche de plateau 9 périphérique alignée radialement sur la cheville de plateau 5, le petit plateau 4 et la cheville de plateau 5 sont dimensionnés de façon à ce que l'axe principal d'inertie de l'ensemble qu'ils constituent l'un avec l'autre soit confondu avec l'axe D du balancier 1 . Avantageusement, l'arbre de balancier 2 comporte des ailettes 1 1 sensiblement radiales pour l'accrochage de la matière plastique de surmoulage, et ces ailettes 1 1 sont équilibrées par rapport à l'axe D du balancier 1 . In this preferred version where the small plate 4 has a peripheral plate notch 9 aligned radially on the plate pin 5, the small plate 4 and the plate pin 5 are dimensioned so that the main axis of inertia of the set that they constitute one with the other is confounded with the axis D of the pendulum 1. Advantageously, the balance shaft 2 comprises fins 1 1 substantially radial for the attachment of the overmoulding plastic, and these fins 1 1 are balanced with respect to the axis D of the balance 1.
De préférence, la matière plastique utilisée pour le surmoulage du petit plateau 4 et de la cheville de plateau 5 est une matière à faible coefficient de frottement inférieur à 0,15, et de préférence compris entre 0,07 et 0,15, choisie pour créer un couple de frottement minimal avec une ancre avec laquelle coopère le balancier, en fonction du matériau de l'ancre.  Preferably, the plastic material used for overmolding the small plate 4 and the plate pin 5 is a material with a low coefficient of friction of less than 0.15, and preferably between 0.07 and 0.15, chosen for create a minimal friction torque with an anchor with which the pendulum cooperates, depending on the material of the anchor.
La figure 3 illustre un ensemble 31 comportant un balancier 1 , et une ancre 21.  FIG. 3 illustrates an assembly 31 comprising a balance 1, and an anchor 21.
Tel que visible sur les figures 3 et 4, un autre mobile 20 est ainsi une ancre 21 , qui comporte des cornes 22 coopérant avec la cheville de plateau 5, un dard 24 coopérant avec l'encoche de plateau 9, et des palettes 23 agencées pour coopérer avec une roue d'échappement 25. Cette ancre 21 est réalisée au moins partiellement en matière plastique :  As can be seen in FIGS. 3 and 4, another mobile 20 is thus an anchor 21, which comprises horns 22 cooperating with the plate pin 5, a pin 24 cooperating with the plate notch 9, and pallets 23 arranged to cooperate with an escape wheel 25. This anchor 21 is made at least partially of plastic:
- soit elle est réalisée entièrement en matière plastique,  - it is made entirely of plastic material,
- soit, de façon préférée comme on le verra plus loin, elle comporte, au moins au niveau de ses zones de coopération avec le balancier 1 (cornes 22) et la roue d'échappement 25 (palettes 23), une peau 210 surmoulée en matière plastique sur un noyau 250 réalisé dans un autre matériau, par exemple étampé, ou issu de fonderie, ou en silicium, ou oxyde de silicium, ou quartz, ou similaire.  - Or, preferably as will be seen later, it comprises, at least at its cooperation areas with the balance 1 (horns 22) and the escape wheel 25 (pallets 23), a skin 210 overmolded in plastic material on a core 250 made of another material, for example stamped, or derived from foundry, or silicon, or silicon oxide, or quartz, or the like.
La figure 4 illustre un autre ensemble 32 comportant une telle ancre 21 et un autre mobile 20 qui est une roue d'échappement 25, comportant des dents 26 coopérant avec les palettes 23 de l'ancre 21 .  FIG. 4 illustrates another assembly 32 comprising such an anchor 21 and another mobile 20 which is an escape wheel 25, having teeth 26 cooperating with the pallets 23 of the anchor 21.
Cette roue d'échappement 25 est réalisée au moins partiellement en matière plastique :  This escape wheel 25 is made at least partially of plastic material:
- soit elle est réalisée entièrement en matière plastique,  - it is made entirely of plastic material,
- soit, de façon préférée comme on le verra plus loin, elle comporte, au moins au niveau de ses zones de coopération avec l'ancre 21 constituées par les dents 26, une peau 210 de surmoulage 28 en matière plastique sur un noyau 27 réalisé dans un autre matériau, par exemple étampé, ou issu de fonderie, ou en silicium, ou oxyde de silicium, ou quartz, ou similaire. Dans un cas comme dans l'autre, l'ensemble 30, 31 ou 32, est agencé de façon à ce que le mécanisme soit thermo-compensé, c'est-à-dire que le jeu des dilatations soit tel que, au point de contact d'interface entre les surfaces périphériques de contact 200 antagonistes (corne 22- cheville 5 pour l'ensemble 31 , dent 26-palette 23 pour l'ensemble 32), les dilatations relatives des deux mobiles antagonistes n'entraînent aucun déplacement différentiel de ce point d'interface. Ainsi, les rétreints ou les gonflements superficiels n'induisent pas de jeux parasites dans le fonctionnement. - Or, preferably as will be seen later, it comprises, at least in its areas of cooperation with the anchor 21 constituted by the teeth 26, a skin 210 overmolding plastic 28 on a core 27 made in another material, for example stamped, or derived from foundry, or silicon, or silicon oxide, or quartz, or the like. In one case as in the other, the assembly 30, 31 or 32 is arranged so that the mechanism is thermo-compensated, that is to say that the set of dilations so that, at the interface contact point 200 between the peripheral contact surfaces 200 (ankle 22-ankle 5 for the assembly 31, tooth 26-pallet 23 for the assembly 32), the relative expansions of the two mobiles antagonists do not cause any differential displacement of this interface point. Thus, necking or superficial swellings do not induce stray play in the operation.
La fabrication composite surmoulée d'au moins un des deux mobiles 20 de chaque ensemble 30 permet de limiter la quantité périphérique de matière plastique de surmoulage, de façon à avoir une dilatation ou une contraction de plastique équivalente à celle de la pièce antagoniste. Naturellement, de façon optimale, dans une paire de mobiles 20 antagonistes d'un même ensemble 30, le noyau ou le corps de base 250 sur lequel est réalisé le surmoulage de la peau 210 de chaque mobile 20 est conçu pour avoir une dilatation radiale, par rapport à son axe de pivotement, équivalente à celle du noyau ou du corps de base 250 sur lequel est réalisé le surmoulage de la peau 210 du mobile 20 antagoniste. La réalisation de tels noyaux ou corps de base 250 en matériaux relativement inertes thermiquement, notamment en matériaux issus des micro-technologies, silicium ou similaire, est avantageuse à ce titre. Le surmoulage périphérique permet de donner aux zones de contact 200 de tels mobiles 20 des propriétés tribologiques différentes de celles des noyaux ou corps de base 250.  The overmolded composite fabrication of at least one of the two mobiles 20 of each assembly 30 makes it possible to limit the peripheral amount of overmolding plastics material, so as to have a plastic expansion or contraction equivalent to that of the counterpart. Naturally, optimally, in a pair of opposing members of the same assembly 30, the core or the base body 250 on which the overmolding of the skin 210 of each mobile 20 is made is designed to have a radial expansion, relative to its pivot axis, equivalent to that of the core or the base body 250 on which is formed the overmolding of the skin 210 of the mobile 20 antagonist. The production of such cores or base bodies 250 in relatively thermally inert materials, especially materials derived from micro-technologies, silicon or the like, is advantageous in this respect. The peripheral overmolding makes it possible to give the contact zones 200 such mobiles 20 tribological properties different from those of the cores or base body 250.
Ainsi, en ce qui concerne le balancier 1 , le petit plateau 4 est de préférence surmoulé seulement en périphérie radiale du flasque de rigidification 6.  Thus, with regard to the rocker 1, the small plate 4 is preferably overmolded only at the radial periphery of the stiffening flange 6.
Dans le cas de la roue d'échappement 25, le noyau 27, réalisé par exemple sous forme de rondelle intermédiaire ou d'étoile, permet de limiter la quantité de matière plastique surmoulée sur la périphérie 28 de la roue d'échappement 25, de sorte à avoir une dilatation de matière plastique équivalente à celle de l'ancre 21 au niveau de ses palettes 23. On obtient ainsi un système thermo-compensé entre les dents 26 et les palettes 23 de l'ancre 21 .  In the case of the escape wheel 25, the core 27, made for example in the form of an intermediate washer or a star, makes it possible to limit the quantity of plastic material overmolded on the periphery 28 of the escape wheel 25, so as to have an expansion of plastic material equivalent to that of the anchor 21 at its pallets 23. This provides a thermo-compensated system between the teeth 26 and the pallets 23 of the anchor 21.
Dans le cas du balancier surmoulé 1 , on peut obtenir la même propriété, pour avoir un système thermo-compensé entre la cheville 5 et les cornes 22 de l'ancre 21 .  In the case of the overmolded balance 1, the same property can be obtained to have a thermo-compensated system between the peg 5 and the horns 22 of the anchor 21.
On comprend que, pour ces deux ensembles 31 , 32, l'exécution de l'ancre 21 en surmoulage sur un noyau permet d'agir sur la quantité de matière soumise à la dilatation/contraction au niveau de l'ancre, ce qui autorise des dimensionnements particuliers du petit plateau 4 et de son flasque 6 d'une part, et de la zone périphérique 28 et de son noyau 27, d'autre part. It is understood that, for these two sets 31, 32, the execution of the anchor 21 overmoulding on a core allows to act on the amount of material subjected to expansion / contraction at the anchor, which allows of the particular dimensions of the small plate 4 and its flange 6 on the one hand, and the peripheral zone 28 and its core 27, on the other hand.
De façon préférée, le même matériau est utilisé pour le surmoulage (ou la confection complète) de chaque mobile 20 d'un tel ensemble 30, de façon à assurer cette thermo-compensation sans autre artifice.  Preferably, the same material is used for overmolding (or the complete manufacture) of each mobile 20 of such an assembly 30, so as to provide this heat compensation without other artifice.
Un ensemble 30 à plus de deux mobiles 20 est constitué, dans le présent exemple, par la est réalisé par la combinaison des ensembles 31 , 32 autour de la même ancre 21 de part et d'autre de laquelle interagissent le balancier 1 et la roue d'échappement 25, chacun réalisé selon les caractéristiques exposées ci-dessus.  An assembly 30 with more than two mobiles 20 is constituted, in the present example, by the is realized by the combination of the sets 31, 32 around the same anchor 21 on both sides of which interact the balance 1 and the wheel exhaust 25, each made according to the characteristics described above.
L'invention concerne encore un ensemble réglant d'horlogerie 10 comportant au moins un tel ensemble 30, et notamment comportant un tel balancier surmoulé 1 .  The invention also relates to a clock setting assembly 10 comprising at least one such assembly 30, and in particular comprising such an overmolded balance 1.
L'invention concerne encore un mouvement d'horlogerie 100 comportant au moins un tel ensemble réglant d'horlogerie 10 ou au moins un tel ensemble 30.  The invention also relates to a watchmaking movement 100 comprising at least one clocking watch assembly 10 or at least one such assembly 30.
L'invention concerne encore une pièce d'horlogerie 1000 comportant au moins un tel ensemble réglant d'horlogerie 10 ou au moins un tel ensemble 30.  The invention also relates to a timepiece 1000 comprising at least one such clock regulation assembly 10 or at least one such assembly 30.
Si l'invention est décrite dans une application particulièrement avantageuse qui est celle d'un mécanisme d'échappement, l'homme du métier comprend qu'elle est applicable à d'autres configurations à l'intérieur d'une pièce d'horlogerie, partout où un différentiel de dilatation entre mobiles antagonistes est susceptible de perturber la marche, d'altérer le rendement, voire de provoquer un blocage d'un mécanisme. Aussi la présente description n'est-elle pas limitative aux mécanismes particuliers décrits.  If the invention is described in a particularly advantageous application which is that of an escape mechanism, one skilled in the art understands that it is applicable to other configurations inside a timepiece, wherever a dilation differential between mobile opposites is likely to disrupt the march, alter the yield, or even cause a blockage of a mechanism. Therefore, the present description is not limited to the particular mechanisms described.
