Description Description

Domaine technique Technical area

[0001] L'invention porte sur un Organe de maintien elastique d'un composant d'horlogerie sur un element de support. The invention relates to an elastic retaining member of a timepiece component on a support element.

[0002] L'invention porte aussi sur un ensemble Organe de maintien elastique - composant d'horlogerie et un assemblagecomprenant un tel ensemble et cet element de support. [0002] The invention also relates to an elastic retaining member assembly - timepiece component and an assembly comprising such an assembly and this support element.

[0003] L'invention porte enfin sur un mouvement d'horlogerie comprenant cet assemblage ainsi que sur une piece d'horlogerie comprenant un tel mouvement. [0003] Finally, the invention relates to a timepiece movement comprising this assembly as well as to a timepiece comprising such a movement.

Arriere-plan technologique Technological background

[0004] Dans l'etat de la technique, on connait des Organes de maintien elastique, tels que des viroles d'horlogerie, realises generalement en des materiaux dits fragiles tels que le silicium qui participent ä des assemblages de spiraux sur des arbres de balancier d'organes de regulation tels que des resonateurs de mouvements d'horlogerie et ce, par un accouplement du type serrage elastique realise ä partir d'un Systeme d'accouplement comprenant des bras deformables tels que des lames elastiques qui sont sollicites classiquement en flexion. [0004] In the state of the art, there are known elastic retaining members, such as clockwork ferrules, generally made of so-called fragile materials such as silicon which participate in the assemblies of hairsprings on balance shafts regulating members such as clockwork resonators, by a coupling of the elastic clamping type produced from a coupling system comprising deformable arms such as elastic blades which are conventionally stressed in bending.

[0005] Toutefois, un des inconvenients majeurs de ces Organes de maintien est lie au fait que le Systeme d'accouplement qu'ils mettent en oeuvre ne permet d'obtenir qu'une faible force de serrage elastique dans les encombrements donnes du fait que la contrainte limite de rupture de la matiere constituant ces Organes de maintien est souvent atteinte rapidement. [0005] However, one of the major drawbacks of these holding members is linked to the fact that the coupling system that they implement only makes it possible to obtain a weak elastic clamping force in the given dimensions because the ultimate breaking stress of the material constituting these retaining members is often reached quickly.

[0006] Le but de l'invention est de proposer une alternative aux Organes de maintien existants. The object of the invention is to provide an alternative to the existing holding bodies.

Resume de l'invention Summary of the invention

[0007] Dans ce dessein, l'invention concerne un Organe de maintien elastique pour la fixation d'un composant d'horlogerie sur un element de support, comportant une portion rigide comprenant une face interieure comprenant au moins trois bras deformables pourvus d'extremites libres definissant une ouverture dans laquelle est susceptible d'etre insere ledit element de support, les bras etant configure pour realiser un accouplement avec l'element de support par un serrage elastique en compression de cet element de support dans l'ouverture. [0007] For this purpose, the invention relates to an elastic retaining member for fixing a timepiece component to a support element, comprising a rigid portion comprising an inner face comprising at least three deformable arms provided with ends free defining an opening in which is capable of being inserted said support element, the arms being configured to perform a coupling with the support element by elastic clamping in compression of this support element in the opening.

[0008] Ainsi de telles caracteristiques participent ä l'obtention d'un Organe de maintien apte ä realiser un accouplement par serrage elastique en compression qui est eleve et ce, sans depasser la contrainte limite de rupture de la matiere constituant cet Organe de maintien. [0008] Thus, such characteristics participate in obtaining a holding member capable of producing a coupling by elastic clamping in compression which is high and this, without exceeding the breaking stress limit of the material constituting this holding member.

[0010] The invention also relates to an elastic retaining member assembly - timepiece component for a clockwork movement of a timepiece comprising such a retaining member.

Description detaillee de l'invention Detailed description of the invention

[0015] Lesfiguresl ä 5 presentent differentes variantes de l'organe de maintien elastique 1a, 1b, 1c pour la fixation d'un composant d'horlogerie 2 sur un element de support 3. Ä titre d'exemple, l'organe de maintien elastique 1a, 1b, 1c peut etre une bague ou encore une virole ou toutes pieces aptes ä assurer la fixation du composant d'horlogerie 2 tel qu'un spiral ou encore une roue, ä un element de support 3 tel qu'un arbre. Cet Organe de maintien elastique 1a, 1b, 1c est realise en une matiere dite „fragile" de preference une matiere micro-usinable. Une teile matiere peut comprendre du silicium,du quartz, du corindon, du silicium et du dioxyde de silicium, DLC, verre metallique, de la ceramique, autre materiau au moins partiellement amorphe, ou similaire. [0015] The figures 1 to 5 show different variants of the elastic holding member 1a, 1b, 1c for fixing a timepiece component 2 to a support element 3. By way of example, the holding member elastic 1a, 1b, 1c can be a ring or even a ferrule or any part capable of ensuring the fixing of the timepiece component 2 such as a hairspring or even a wheel, to a support element 3 such as a shaft. This elastic retaining member 1a, 1b, 1c is made of a so-called "fragile" material, preferably a micro-machinable material. Such a material may include silicon, quartz, corundum, silicon and silicon dioxide, DLC , metallic glass, ceramic, other at least partially amorphous material, or the like.

[0016] Dans ce mode de realisation, cet Organe de maintien 1a, 1b, 1c peut etre compris dans un ensemble 120 Organe de maintien elastique - composant d'horlogerie. Un tel ensemble 120 est prevu pour etre agence dans un mouvementd'horlogerie 110 d'une piece d'horlogerie 100 visible sur la figure 3, et egalement prevu pour etre monte sur un element de support 3. Un tel ensemble 120 peut etre une piece monobloc et etre realise dans une matiere „fragile" similaire ä celle de l'organe de maintien 1. On notera que dans une Variante de cet ensemble 120, seul l'organe de maintien elastique 1a, 1b, 1 c peut etre realise en une teile matiere dite „fragile", le composant d'horlogerie 2 etant alors fabrique en une autre matiere. In this embodiment, this holding member 1a, 1b, 1c can be included in a set 120 elastic holding member - watch component. Such an assembly 120 is intended to be arranged in a clockwork movement 110 of a timepiece 100 visible in FIG. 3, and also intended to be mounted on a support element 3. Such an assembly 120 can be a piece monobloc and be made of a "fragile" material similar to that of the holding member 1. It will be noted that in a variant of this assembly 120, only the elastic holding member 1a, 1b, 1c can be made in this so-called "fragile" material, the watch component 2 then being made of another material.

[0017] Cet ensemble 120 peut faire partie d'un assemblage 130 pour le mouvement horlogerie 110. Un tel assemblage 130 a ici ete imagine pour des applications dans le domaine horloger. Toutefois, cet assemblage 130 peut parfaitement etre mis en oeuvre dans d'autres domaines tels que l'aeronautique, la bijouterie, ou encore l'automobile. This assembly 120 can be part of an assembly 130 for the watch movement 110. Such an assembly 130 has here been imagined for applications in the watchmaking field. However, this assembly 130 can perfectly be implemented in other fields such as aeronautics, jewelry, or even automobiles.

[0018] Un tel Organe de maintien 1a, 1b, 1c est de preference une piece monobloc qui comprend une face superieure et une face Interieure de preference planes qui sont toutes deux comprises respectivement dans des premier et deuxieme plans PI et P2. Cet Organe 1a, 1b, 1c presente aussi une epaisseur qui s'etend de la face superieure ä la face Interieure. Un tel organe de maintien 1a, 1b, 1c comprend egalement une portion rigide 7 pourvue d'une face interieure 6. Cette portion rigide 7 correspond ä la partie de l'organe de maintien 1a, 1b, 1c qui comprend le volume le plus important de matiere. L'organe de maintien 1a, 1b, 1c peut aussi comprendre une face exterieure ou paroi peripherique externe notamment lorsqu'il s'agit d'une virole qui est notamment destinee ä etre reliee au composant d'horlogerie 2 par l'intermediaire d'au moins un point d'attache agence dans cette face exterieure. Dans une Variante une teile face exterieure, et donc l'organe de maintien 1, peut etre venue de matiere avec le composant d'horlogerie 2 lorsque ce dernier est une roue visible sur les figures 1 et 2. Such a holding member 1a, 1b, 1c is preferably a one-piece piece which comprises an upper face and an inner face, preferably planar, which are both included respectively in the first and second planes PI and P2. This member 1a, 1b, 1c also has a thickness which extends from the upper face to the inner face. Such a holding member 1a, 1b, 1c also comprises a rigid portion 7 provided with an inner face 6. This rigid portion 7 corresponds to the part of the holding member 1a, 1b, 1c which comprises the largest volume of matter. The holding member 1a, 1b, 1c can also comprise an outer face or outer peripheral wall, in particular when it is a ferrule which is in particular intended to be connected to the timepiece component 2 by means of at least one attachment point arranged in this outer face. In a variant, a teile exterior face, and therefore the retaining member 1, can be made in one piece with the timepiece component 2 when the latter is a wheel visible in Figures 1 and 2.

[0019] Dans cette organe de maintien 1a, 1b, 1c, la face interieure 6 participe ä definir un volume 5 dans lequel sont agences au moins trois bras deformables 4 pourvus d'extremites libres 9. Dans le present mode de realisation, cet organe 1a, 1b, 1c comprend six bras 4 representes sur les figures 1 et 2. On remarquera que ce volume 5 n'est que partiellement occupe par ces bras deformables 4. De tels bras 4 sont compris dans la face interieure 6 et s'etendent radialement de cette face 6 vers un axe central A dudit organe de maintien 1a, 1b, 1c. Dans la premiere Variante illustree sur les figures 1 et 2, ces bras deformables 4 sont constitues essentiellement d'une partie principale 8 pleine/non-ajouree, comportantune quantite de matiere qui decroit regulierement selon une direction s'etendant de cette face interieure 6 vers Taxe central A. Dans les deuxieme et troisieme variantes visibles sur les figures 3 et 4, les bras deformables 4 sont constitues essentiellement d'une partie principale 8 ajouree, avec un ajourage 14 plus important dans la troisieme Variante que celui 13 de la deuxieme Variante. Dans ces deuxieme et troisieme variantes, la quantite de matiere decroit aussi regulierement selon une direction s'etendant de cette face interieure 6 vers Taxe central A. En complement, on comprend donc que la quantite de matiere dans la partie principale 8 de chaque bras 4 de la troisieme Variante est moindre que dans celle de chaque bras 4 de la deuxieme et encore moindre que dans celle de chaque bras 4 de la premiere Variante. [0019] In this holding member 1a, 1b, 1c, the inner face 6 participates in defining a volume 5 in which are arranged at least three deformable arms 4 provided with free ends 9. In the present embodiment, this member 1a, 1b, 1c comprises six arms 4 shown in Figures 1 and 2. It will be noted that this volume 5 is only partially occupied by these deformable arms 4. Such arms 4 are included in the inner face 6 and extend radially from this face 6 towards a central axis A of said retaining member 1a, 1b, 1c. In the first variant illustrated in FIGS. 1 and 2, these deformable arms 4 consist essentially of a solid/non-perforated main part 8, comprising a quantity of material which decreases regularly in a direction extending from this inner face 6 towards Central tax A. In the second and third variants visible in Figures 3 and 4, the deformable arms 4 essentially consist of a perforated main part 8, with a larger opening 14 in the third variant than that 13 of the second variant . In these second and third variants, the quantity of material also decreases regularly in a direction extending from this inner face 6 towards the central axis A. In addition, it is therefore understood that the quantity of material in the main part 8 of each arm 4 of the third Variant is less than in that of each arm 4 of the second and even less than in that of each arm 4 of the first Variant.

[0020] On notera que chacun de ces bras 4 presente de preference une forme essentiellement trapezoidale. It will be noted that each of these arms 4 preferably has an essentially trapezoidal shape.

[0021] Ces bras deformables 4 comprennent chacun deux extremites, une premiere extremite reliee ä la face interieure 6 de l'organe de maintien 1a, 1b, 1c et une deuxieme extremite qui est l'extremite libre 9 visible sur la figure 1. Cette extremite libre 9 comprend une face de contact 10 ayant une forme configuree/adaptee pour cooperer avec une zone de montage de l'element de support 3 destinee ä cooperer avec cette face de contact 10. A titre d'exemple dans ces variantes, lorsque cette zone de montage est definie sur une partie de forme cylindrique de l'element de support 3 alors la face de contact 10 presente une forme compatible apte ä epouser cette forme cylindrique en etant par exemple une face de contact courbee 10. Les extremites libres 9 de ces bras 4 definissent ensemble une ouverture 12 dans laquelle est susceptible d'etre insere ledit element de support 3. Cette ouverture 12 definit un volume dans l'organe de maintien 1a, 1b, 1 c qui est Interieur ä celui de la zone de montage comprise dans une extremite de l'element de support 3 qui est prevue pour y etre agencee. [0021] These deformable arms 4 each comprise two ends, a first end connected to the inner face 6 of the holding member 1a, 1b, 1c and a second end which is the free end 9 visible in FIG. free end 9 comprises a contact face 10 having a shape configured/adapted to cooperate with a mounting zone of the support element 3 intended to cooperate with this contact face 10. By way of example in these variants, when this mounting zone is defined on a cylindrical shaped part of the support element 3 then the contact face 10 has a compatible shape capable of marrying this cylindrical shape by being for example a curved contact face 10. The free ends 9 of these arms 4 together define an opening 12 into which said support element 3 can be inserted. This opening 12 defines a volume in the holding member 1a, 1b, 1c which is inside that of the mounting zone included in one end of the support element 3 which is planned to be arranged there.

[0022] Dans ce contexte, la zone de montage de l'element de support 3, comprend en tout ou partie des portions de contact 13 de cet element de support 3 avec l'organe de maintien 1a, 1b, 1 c qui sont definies sur une paroi peripherique [0022] In this context, the mounting zone of the support element 3 comprises all or part of the contact portions 13 of this support element 3 with the holding member 1a, 1b, 1c which are defined on a peripheral wall

Claims (12)

de cet element de support 3 et qui sont prevues notamment pour cooperer avec les bras 4 de cet Organe de maintien 1a, 1b, 1c. On notera que cet element de support 3 comprend au moins autant de portions 10 que l'organe de maintien 1a, 1b, 1c comprend de bras 4. of this support element 3 and which are provided in particular to cooperate with the arms 4 of this holding member 1a, 1b, 1c. It will be noted that this support element 3 comprises at least as many portions 10 as the holding member 1a, 1b, 1c comprises arms 4. [0023] Dans cet Organe de maintien 1, chaque bras 4 est apte ä etre deforme en compression c'est-ä-dire radialementrelativement ä Taxe central A de l'organe de maintien qui est confondu avec celui de Taxe de l'ouverture 5. Autrement dit, chacun de ces bras 4 lorsqu'il est soumis ä une contrainte induite par l'element de support 3 comme on le verra par la suite, est apte ä etre deforme en passant d'une configuration de repos ä une configuration de sous contrainte. Dans ce contexte, en passant de cette configuration de repos ä la configuration sous contrainte, tout ou partie de ce bras 4 est alors comprimee radialement relativement ä faxe centrale A et ce, vers la face Interieure 6 de l'organe de maintien 1. De tels bras 4 exercent une force contre l'element de support permettant ainsi d'assurer un accouplement par serrage elastique de l'element de support 3 dans l'ouverture 12 en etant configure pour etre comprime/deforme radialement relativement ä Taxe central A de ladite ouverture 5. [0023] In this retaining member 1, each arm 4 is capable of being deformed in compression, that is to say radially relative to the central axis A of the retaining member which coincides with that of the axis of the opening 5 In other words, each of these arms 4 when it is subjected to a stress induced by the support element 3 as will be seen later, is able to be deformed by passing from a configuration of rest to a configuration of under constraint. In this context, passing from this configuration at rest to the configuration under stress, all or part of this arm 4 is then compressed radially relative to the central axis A and this, towards the internal face 6 of the holding member 1. such arms 4 exert a force against the support element thus making it possible to ensure a coupling by elastic clamping of the support element 3 in the opening 12 while being configured to be compressed/deformed radially with respect to the central axis A of said opening 5. [0024] On notera que la disposition des bras deformables 4 dans l'organe de maintien 1 a, 1 b, 1 c permet lors d'une insertion avec serrage, une deformation de chaque bras 4 permettant d'accommoder la deformation de l'organe de maintien 1a, 1b, 1c avec la geometrie de la zone de montage de l'element de support 3. [0024] It will be noted that the arrangement of the deformable arms 4 in the holding member 1 a, 1 b, 1 c allows during insertion with clamping, a deformation of each arm 4 making it possible to accommodate the deformation of the holding member 1a, 1b, 1c with the geometry of the mounting zone of the support element 3. [0025] Ainsi, lors du montage de cet Organe de maintien 1a, 1b, 1 c sur l'element de support 3, une extremite de cet element de support 3 comprenant la zone de montage est alors inseree dans l'ouverture 12 definie dans l'organe de maintien 1. Dans ce contexte, cette zone de montage qui comprend les portions de contact 13 de cet element de support 3, est de preference agencee de maniere coaxiale avec l'ouverture 12 et ce, autour de Taxe central A qui est commun ä cette zone de montage et ä cette ouverture 12 de l'organe de maintien 1. Un tel agencement autour de cette axe commun A participe ä un indexage de cette zone de montage par rapport ä l'ouverture 12 durant cette insertion. Plus precisement, lors de cette insertion, les faces de contact 10 subissent une deformation radiale donc les bras 4 subissent alors une deformation elastique sous l'effet de l'application sur les faces de contact 10 des bras 4 par les portions de contact 13 de la zone de montage de l'element de support 3, d'une force de compression F illustree sur la figure 2. Une teile force de compression F engendre une deformation elastique en compression de chaque bras 4 dans une direction radiale par rapport ä Taxe central A et ce, vers la premiere extremite du bras 4 reliee ä la face Interieure 6 de l'organe de maintien 1a, 1b, 1c. Une teile deformation participe notamment ä ce que l'organe de maintien 1a, 1b, 1c emmagasine une quantite importante d'energie elastique qui contribue ä lui conferer un couple de tenue consequent autorisant notamment une tenue optimale par serrage elastique en compression. On notera de plus, qu'un tel Organe elastique 1a, 1b, 1c permet d'augmenter de maniere consequente la force de serrage en comparaison avec les Organes elastiques de l'etat de la technique, en effet cette force de serrage est ici environ deux fois plus importante que celle des Organes de l'etat de la technique pour une meme configuration. Thus, when mounting this holding member 1a, 1b, 1c on the support element 3, one end of this support element 3 comprising the mounting zone is then inserted into the opening 12 defined in the holding member 1. In this context, this mounting zone which includes the contact portions 13 of this support element 3, is preferably arranged coaxially with the opening 12 and this, around the central axis A which is common to this assembly area and to this opening 12 of the holding member 1. Such an arrangement around this common axis A participates in an indexing of this assembly area with respect to the opening 12 during this insertion. More precisely, during this insertion, the contact faces 10 undergo a radial deformation therefore the arms 4 then undergo an elastic deformation under the effect of the application on the contact faces 10 of the arms 4 by the contact portions 13 of the mounting area of the support element 3, of a compression force F illustrated in Figure 2. Such a compression force F generates an elastic deformation in compression of each arm 4 in a direction radial with respect to the central axis A and this, towards the first end of the arm 4 connected to the inner face 6 of the holding member 1a, 1b, 1c. Such a deformation contributes in particular to the fact that the holding member 1a, 1b, 1c stores a large quantity of elastic energy which contributes to conferring on it a consequent holding torque, in particular authorizing optimum holding by elastic tightening in compression. It will also be noted that such an elastic member 1a, 1b, 1c makes it possible to increase the clamping force accordingly in comparison with the elastic members of the state of the art, in fact this clamping force is here approximately twice as high as that of the bodies of the state of the art for the same configuration.
