A titre d'exemples, les demandes de brevet CH700024 , WO2012079976 , EP1826634 divulguent respectivement une virole d'un ressort-spiral et des roues comprenant chacune une structure élastique dotée de plusieurs bras élastiques encastrés à une seule de leur extrémité. Une telle structure, caractérisée par un contour ouvert ou discontinu, peut s'avérer particulièrement fragile et cassante. Par ailleurs, les forces de serrage escomptées peuvent s'avérer faibles.For example, patent applications CH700024 , WO2012079976 , EP1826634 respectively disclose a ferrule of a spiral spring and wheels each comprising an elastic structure provided with several elastic arms embedded at only one of their ends. Such a structure, characterized by an open or discontinuous contour, can prove to be particularly fragile and brittle. Furthermore, the expected clamping forces may turn out to be low.

Alternativement, de telles structures élastiques peuvent, par exemple, comprendre un contour fermé ou continu. A titre d'exemples, les demandes de brevet WO2016192957 et EP3056948 divulguent des viroles respectivement dotées de trois bras élastiques et de quatre bras élastiques, qui font saillie vers l'intérieur d'une première ouverture principale de réception de l'axe, de sorte à venir en contact avec l'axe lors de l'opération de chassage. Ces viroles, de forme trilobée ou quadrilobée, comprennent chacune des deuxièmes ouvertures débouchant vers la première ouverture principale. Celles-ci sont conformées pour maximiser la longueur active des bras élastiques, en définissant des points d'encastrement des bras élastiques les plus éloignés possibles du centre de la première ouverture principale. Lors de l'opération de chassage de l'axe, les points d'appui de l'axe sont déplacés radialement relativement à l'axe géométrique de l'axe sous l'effet du fléchissement de chacun des bras élastiques. La force de serrage est principalement donnée par la raideur de chacun des bras, qui est ici donnée par la hauteur et l'épaisseur de la virole. Une telle géométrie est donc limitante.Alternatively, such elastic structures may, for example, comprise a closed or continuous contour. For example, patent applications WO2016192957 And EP3056948 disclose ferrules respectively equipped with three elastic arms and four elastic arms, which project towards the inside of a first main opening for receiving the axis, so as to come into contact with the axis during the operation hunting. These ferrules, of trilobed or quadrilobed shape, comprise each of the second openings opening towards the first main opening. These are shaped to maximize the active length of the elastic arms, by defining embedding points of the elastic arms as far away as possible from the center of the first main opening. During the operation of driving out the axis, the support points of the axis are displaced radially relative to the geometric axis of the axis under the effect of the bending of each of the elastic arms. The clamping force is mainly given by the stiffness of each of the arms, which is here given by the height and thickness of the ferrule. Such geometry is therefore limiting.

La demande de brevet JP2012185128 divulgue, quant à elle, une structure élastique comprenant des deuxièmes ouvertures prenant la forme de fentes, qui débouchent vers une première ouverture de réception d'un axe. L'étendue de ces fentes définissent, en conjonction avec des troisièmes ouvertures prenant la forme de portions de couronnes circulaires, l'étendue de bras élastiques prévus pour venir en contact avec un axe. Autrement dit, les zones d'encastrement des bras élastiques sont définies par ces deuxièmes ouvertures, et non exclusivement par des troisièmes ouvertures.The patent application JP2012185128 discloses, for its part, an elastic structure comprising second openings taking the form of slots, which open towards a first opening for receiving an axis. The extent of these slots define, in conjunction with third openings taking the form of portions of circular crowns, the extent of elastic arms intended to come into contact with an axis. In other words, the embedding zones of the elastic arms are defined by these second openings, and not exclusively by third openings.

La problématique de mal-rond susceptible d'être engendrée par de telles structures élastiques est abordée par la demande de brevet EP2219083 . Pour pallier cette problématique, cette demande de brevet propose de mettre en oeuvre une structure élastique proche de celle divulguée par la demande JP2012185128 . Cette structure élastique, divulguée au sein d'une roue d'échappement, comprend également des deuxièmes ouvertures prenant la forme de fentes, qui débouchent vers une première ouverture de réception d'un axe. L'étendue de ces fentes définissent, en conjonction avec des troisièmes ouvertures prenant la forme de portions de couronnes circulaires, l'étendue de bras élastiques prévus pour venir en contact avec un axe. Afin de minimiser la déformation de la serge de cette roue, la structure élastique comprend en outre des quatrièmes ouvertures prenant la forme de multiples fentes oblongues de différentes étendues, qui sont disposées à l'interface des deuxièmes et troisièmes ouvertures et de la denture de la roue d'échappement. Ces quatrièmes ouvertures sont ici prévues pour se déformer et ainsi absorber les déformations induites par la déformation des bras élastiques. L'esthétique de la roue d'échappement est donnée par la géométrie de la structure élastique, qui occupe ici la majeure partie de la planche de la roue d'échappement. Une telle structure élastique est donc difficilement transposable à une esthétique prédéfinie de composant horloger. Elle est également difficilement transposable à toute dimension de composant horloger.The problem of out-of-roundness likely to be generated by such elastic structures is addressed by the patent application EP2219083 . To overcome this problem, this patent application proposes to implement an elastic structure close to that disclosed by the application JP2012185128 . This elastic structure, disclosed within an escape wheel, also comprises second openings taking the form of slots, which open towards a first opening for receiving an axle. The extent of these slots define, in conjunction with third openings taking the form of portions of circular crowns, the extent of elastic arms intended to come into contact with an axis. In order to minimize the deformation of the rim of this wheel, the elastic structure further comprises fourth openings taking the form of multiple oblong slots of different extents, which are arranged at the interface of the second and third openings and the teeth of the escape wheel. These fourth openings are here designed to deform and thus absorb the deformations induced by the deformation of the elastic arms. The aesthetics of the escape wheel are given by the geometry of the elastic structure, which here occupies most of the escape wheel board. Such an elastic structure is therefore difficult to transpose to a predefined aesthetic of a watch component. It is also difficult to transpose to any size of watch component.

Le composant horloger comprend une première ouverture 1 destinée à recevoir l'organe 20 par chassage de ce dernier dans ladite ouverture.The watch component comprises a first opening 1 intended to receive the member 20 by driving the latter into said opening.

L'organe, notamment une partie de l'organe destinée à être chassée dans le composant horloger, peut être réalisé en matériau fragile, notamment en une céramique ou en rubis. La partie d'organe peut être un arbre, notamment un arbre de forme cylindrique ou sensiblement cylindrique.The member, in particular a part of the member intended to be driven into the watch component, can be made of fragile material, in particular ceramic or ruby. The organ part may be a shaft, in particular a shaft of cylindrical or substantially cylindrical shape.

Dans le premier mode de réalisation, le composant 100 est une roue d'échappement. Le composant 100 peut être une roue d'un autre type ou le composant 100 peut être d'une autre nature. Dans le premier mode de réalisation, la roue d'échappement 100 peut présenter un diamètre extérieur D6 du moyeu 6 avantageusement inférieur à D9/2, voire inférieur à D9/3, voire inférieur à D9/4, avec D9 le diamètre de tête d'une denture 9 disposée sur une serge 8 de la roue 100.In the first embodiment, component 100 is an escape wheel. The component 100 may be a wheel of another type or the component 100 may be of another nature. In the first embodiment, the escape wheel 100 may have an external diameter D6 of the hub 6 advantageously less than D9/2, or even less than D9/3, or even less than D9/4, with D9 the head diameter d a toothing 9 arranged on a serge 8 of the wheel 100.

Le composant horloger et l'organe sont représentés en coupe sur les figures, en particulier en coupe selon un plan perpendiculaire à une direction ou à un axe A1 selon laquelle l'organe est chassé dans le composant.The watch component and the organ are shown in section in the figures, in particular in section along a plane perpendicular to a direction or to an axis A1 according to which the member is driven into the component.

Le composant horloger 100 comprend la première ouverture 1 destinée à recevoir l'organe 20 par chassage de ce dernier dans la première ouverture. L'axe A1 est centré dans la première ouverture. Le composant horloger 100 comprend au moins deux structures de réception 10 de l'organe.The watch component 100 comprises the first opening 1 intended to receive the member 20 by driving the latter into the first opening. Axis A1 is centered in the first opening. The watch component 100 comprises at least two structures for receiving the member.

Chaque structure de réception comprend :

  • un élément de réception 4b destiné à venir en contact avec l'organe et s'étendant au moins sensiblement orthoradialement relativement à l'axe A1,
  • un premier élément de liaison 4c s'étendant au moins sensiblement radialement relativement à l'axe A1 à partir d'une première extrémité de l'élément de réception,
  • un deuxième élément de liaison 4d s'étendant au moins sensiblement radialement relativement à l'axe A1 à partir d'une deuxième extrémité de l'élément de réception,
  • un premier élément élastiquement déformable 4a s'étendant au moins sensiblement orthoradialement relativement à l'axe A1, et
  • un deuxième élément élastiquement déformable 4a' s'étendant au moins sensiblement orthoradialement relativement à l'axe A1.
Each reception structure includes:
  • a receiving element 4b intended to come into contact with the organ and extending at least substantially orthoradially relative to the axis A1,
  • a first connecting element 4c extending at least substantially radially relative to the axis A1 from a first end of the receiving element,
  • a second connecting element 4d extending at least substantially radially relative to the axis A1 from a second end of the receiving element,
  • a first elastically deformable element 4a extending at least substantially orthoradially relative to the axis A1, and
  • a second elastically deformable element 4a' extending at least substantially orthoradially relative to the axis A1.

Le premier élément de liaison relie mécaniquement la première extrémité de l'élément de réception au premier élément élastiquement déformable et le deuxième élément de liaison relie mécaniquement la deuxième extrémité de l'élément de réception au deuxième élément élastiquement déformable.The first connecting element mechanically connects the first end of the receiving element to the first elastically deformable element and the second connecting element mechanically connects the second end of the receiving element to the second elastically deformable element.

L'élément de réception 4b comprend une zone d'appui s'étendant entre deux extrémités 1a, 1b de l'élément de réception 4b, notamment d'une première extrémité 1a à une deuxième extrémité 1b. Cette zone d'appui est destinée à venir au contact de l'organe 20, notamment au contact d'un arbre de l'organe. Ces extrémités sont définies par des intersections de la première ouverture 1 et de deuxièmes ouvertures 2, 2". La zone d'appui peut comprendre une seule surface continue. En variante, la zone d'appui peut comprendre plusieurs surfaces, notamment plusieurs surfaces allongées, en particulier allongées parallèlement à l'axe A1. Ainsi, l'élément de réception comprend au moins une surface ou un point de contact destiné à venir en contact avec l'organe. De préférence, l'élément de réception 4b comprend une première zone d'appui linéique ou linéaire s'étendant par exemple parallèlement à l'axe A1 au niveau d'une première extrémité 1a de l'élément de réception 4b et une deuxième zone d'appui linéique ou linéaire s'étendant par exemple parallèlement à l'axe A1 à une deuxième extrémité 1b de l'élément de réception 4b. Ainsi, la première zone d'appui et/ou la deuxième zone d'appui a une forme de ligne ou sensiblement une forme de ligne.The receiving element 4b comprises a support zone extending between two ends 1a, 1b of the receiving element 4b, in particular from a first end 1a to a second end 1b. This support zone is intended to come into contact with the member 20, in particular in contact with a shaft of the member. These ends are defined by intersections of the first opening 1 and second openings 2, 2". The support zone may comprise a single continuous surface. Alternatively, the support zone may comprise several surfaces, in particular several elongated surfaces , in particular elongated parallel to the axis A1. Thus, the receiving element comprises at least one surface or a contact point intended to come into contact with the member. Preferably, the receiving element 4b comprises a first linear or linear support zone extending for example parallel to the axis A1 at a first end 1a of the receiving element 4b and a second linear or linear support zone extending for example parallel to the axis A1 at a second end 1b of the receiving element 4b. Thus, the first support zone and/or the second support zone has a line shape or substantially a line shape.

La première ouverture 1 présente, au repos, c'est-à-dire quand aucun organe n'est introduit dans l'ouverture, une géométrie sensiblement cylindrique de diamètre D1. Ce diamètre D1 est le diamètre du cylindre de plus grand diamètre qui puisse être inscrit dans l'ouverture. L'axe A1 est défini comme étant l'axe de révolution de ce cylindre de plus grand diamètre. En ce sens, la première ouverture 1 est centrée sur l'axe A1.The first opening 1 has, at rest, that is to say when no member is introduced into the opening, a substantially cylindrical geometry of diameter D1. This diameter D1 is the diameter of the largest diameter cylinder that can be inscribed in the opening. Axis A1 is defined as being the axis of revolution of this cylinder of largest diameter. In this sense, the first opening 1 is centered on the axis A1.

Lors du chassage de l'organe 20, un axe géométrique A2 de l'organe, notamment l'axe A2 de symétrie ou de révolution d'un arbre de l'organe 20 est prévu pour être aligné ou sensiblement aligné avec l'axe géométrique A1 de la structure 10.When driving out the member 20, a geometric axis A2 of the member, in particular the axis A2 of symmetry or revolution of a shaft of the member 20 is provided to be aligned or substantially aligned with the geometric axis A1 of structure 10.

Le composant horloger peut comprendre trois structures de réception 10 de l'organe. Avantageusement, les structures de réception constituent un ensemble ayant une symétrie de rotation d'ordre 3. En conséquence, on ne décrit ici en détail qu'une structure de réception. Les autres structures de réception se déduisent de la structure de réception décrite par des rotations autour de l'axe A1. Un élément d'une autre structure qui est similaire ou qui assure la même fonction qu'un élément de la structure de réception décrite est identifié par la même référence numérique à laquelle est ajouté « ' » ou « " ».The watch component may comprise three structures for receiving the member. Advantageously, the receiving structures constitute a set having a rotational symmetry of order 3. Consequently, only one receiving structure is described here in detail. The other reception structures are deduced from the reception structure described by rotations around the axis A1. An element of another structure which is similar or which provides the same function as an element of the described receiving structure is identified by the same numerical reference to which "'" or "" is added.

Avantageusement, le composant est conformé de sorte que, lorsque l'organe 20 est introduit dans la première ouverture, les éléments élastiquement déformables sont principalement sollicités en flexion et/ou les éléments de liaison sont principalement sollicités en compression et/ou les éléments de réception sont principalement sollicités en flexion.Advantageously, the component is shaped so that, when the member 20 is introduced into the first opening, the elastically deformable elements are mainly stressed in bending and/or the connecting elements are mainly stressed in compression and/or the receiving elements are mainly stressed in bending.

Avantageusement, le composant comprend les deuxièmes ouvertures 2, 2', 2" s'étendant au moins sensiblement radialement relativement à l'axe A1 et débouchant dans la première ouverture. Chaque deuxième ouverture limite orthoradialement deux éléments de réception de deux structures de réception adjacentes et/ou chaque deuxième ouverture sépare un premier élément de liaison d'un deuxième élément de liaison de deux structures de réception adjacentes. Les deuxièmes ouvertures 2 sont par exemple des fentes s'étendant radialement relativement à l'axe A1 depuis la première ouverture 1. La profondeur des fentes (mesurée radialement à l'axe A1) est par exemple supérieure à deux fois la largeur des fentes (mesurée orthoradialement à l'axe A1).Advantageously, the component comprises the second openings 2, 2', 2" extending at least substantially radially relative to the axis A1 and opening into the first opening. Each second opening orthoradially limits two receiving elements of two adjacent receiving structures and/or each second opening separates a first connecting element from a second connecting element of two adjacent receiving structures. The second openings 2 are for example slots extending radially relative to the axis A1 from the first opening 1 The depth of the slots (measured radially to axis A1) is for example greater than twice the width of the slots (measured orthoradially to axis A1).

Préférentiellement, les deuxièmes ouvertures 2, 2', 2" présentent des formes en U c'est-à-dire avec un fond arrondi, en V c'est-à-dire avec un fond linéique ou sensiblement linéique, ou en créneau c'est-à-dire avec un fond plat. Préférentiellement, les deuxièmes ouvertures 2, 2', 2" sont inscrites dans un cylindre de diamètre minimal D2, avec le diamètre D2 compris entre 1.1 fois et 3 fois le diamètre D1.Preferably, the second openings 2, 2', 2" have U shapes, that is to say with a rounded bottom, V shapes, that is to say with a linear or substantially linear bottom, or crenelated, that is to say with a flat bottom. Preferably, the second openings 2, 2', 2" are inscribed in a cylinder of minimum diameter D2, with the diameter D2 between 1.1 times and 3 times the diameter D1.

Préférentiellement, la largeur d des ouvertures (mesurée orthoradialement à l'axe A1) est donnée par la relation 2×d=α×D1 avec α compris entre 0.17 et 0.7.Preferably, the width d of the openings (measured orthoradially to axis A1) is given by the relationship 2×d=α×D1 with α between 0.17 and 0.7.

Des troisièmes ouvertures 3, 3', 3" (ne débouchant ni dans la première ouverture 1, ni dans les deuxièmes ouvertures) permettent, en complément des première et deuxièmes ouvertures, de définir les géométries des structures de réception.Third openings 3, 3', 3" (opening neither into the first opening 1 nor into the second openings) make it possible, in addition to the first and second openings, to define the geometries of the receiving structures.

Les troisièmes ouvertures comprennent principalement une première portion d'ouverture 3a s'étendant orthoradialement ou sensiblement orthoradialement relativement à l'axe A1 au niveau d'un premier diamètre D3a, une deuxième portion d'ouverture 3b s'étendant orthoradialement ou sensiblement orthoradialement relativement à l'axe A1 au niveau d'un deuxième diamètre D3b et une troisième portion d'ouverture 3c s'étendant radialement ou sensiblement radialement relativement à l'axe A1 de la première portion à la deuxième portion, notamment d'une extrémité de la première portion à une extrémité de la deuxième portion.The third openings mainly comprise a first opening portion 3a extending orthoradially or substantially orthoradially relative to the axis A1 at the level of a first diameter D3a, a second opening portion 3b extending orthoradially or substantially orthoradially relative to the axis A1 at the level of a second diameter D3b and a third opening portion 3c extending radially or substantially radially relative to the axis A1 from the first portion to the second portion, in particular from one end of the first portion at one end of the second portion.

Le deuxième diamètre D3b est inférieur au premier diamètre D3a. Par exemple, les diamètres D3b et D3a peuvent être liés ou sensiblement liés par la relation suivante : 2× D3b =D1+ D3a.The second diameter D3b is less than the first diameter D3a. For example, the diameters D3b and D3a can be linked or substantially linked by the following relationship: 2× D3b =D1+ D3a.

Par exemple, la première portion 3a peut s'étendre angulairement sur 1.5×π/N autour de l'axe A1, avec N le nombre de structures de réception.For example, the first portion 3a can extend angularly over 1.5×π/N around the axis A1, with N the number of receiving structures.

Par exemple, la deuxième portion 3b peut s'étendre angulairement sur 0.8×π/N autour de l'axe A1, avec N le nombre de structures de réception.For example, the second portion 3b can extend angularly over 0.8×π/N around the axis A1, with N the number of receiving structures.

Alternativement, les première et deuxième portions 3a, 3b peuvent s'étendre angulairement sur le même angle ou sensiblement sur le même angle autour de l'axe A1.Alternatively, the first and second portions 3a, 3b can extend angularly over the same angle or substantially over the same angle around the axis A1.

Avantageusement encore, le premier élément élastiquement déformable et/ou le deuxième élément élastiquement déformable a une structure de poutre encastrée à une seule de ses extrémités. Cet encastrement est réalisé au niveau du moyeu ou au niveau de deuxièmes bras 5 liés au moyeu.Advantageously again, the first elastically deformable element and/or the second elastically deformable element has a beam structure embedded at only one of its ends. This embedding is carried out at the level of the hub or at the level of second arms 5 linked to the hub.

Avantageusement, le composant comprend des troisièmes ouvertures 3 comprenant chacune une première portion 3a s'étendant au moins sensiblement orthoradialement relativement à l'axe A1, une deuxième portion 3b s'étendant au moins sensiblement orthoradialement relativement à l'axe A1 et une troisième portion 3c s'étendant au moins sensiblement radialement relativement à l'axe A1.Advantageously, the component comprises third openings 3 each comprising a first portion 3a extending at least substantially orthoradially relative to the axis A1, a second portion 3b extending at least substantially orthoradially relative to the axis A1 and a third portion 3c extending at least substantially radially relative to axis A1.

De préférence, la première portion 3a délimite, radialement relativement à l'axe A1, un élément élastiquement déformable 4a et/ou la deuxième portion 3b délimite, radialement relativement à l'axe A1, un élément de réception 4b" et/ou la troisième portion 3c délimite, orthoradialement relativement à l'axe A1, un élément de liaison 4d".Preferably, the first portion 3a delimits, radially relative to the axis A1, an elastically deformable element 4a and/or the second portion 3b delimits, radially relative to the axis A1, a receiving element 4b" and/or the third portion 3c delimits, orthoradially relative to axis A1, a connecting element 4d".

Une telle géométrie d'ouvertures permet de définir un bras 4 comprenant :

  • une première portion 4a de bras 4,
  • une deuxième portion 4c de bras 4,
  • une troisième portion 4b de bras 4, et
  • une quatrième portion 4d de bras 4.
Such an opening geometry makes it possible to define an arm 4 comprising:
  • a first portion 4a of arm 4,
  • a second portion 4c of arm 4,
  • a third portion 4b of arm 4, and
  • a fourth portion 4d of arm 4.

La première portion 4a est encastrée dans le deuxième bras 5 s'étendant, depuis le moyeu 6, notamment depuis une surface interne 61 du moyeu, selon une direction radiale ou sensiblement radiale relativement à l'axe A1. L'encastrement est ici défini par deux ouvertures 3, 3', en particulier par les portions 3a, 3b' et 3c'. Plus particulièrement, une section du bras 4, au niveau de sa première portion 4a, est définie par les diamètres D3a, D3b, ainsi que par la largeur L (mesurée radialement relativement à l'axe A1) des portions 3a, 3b'. La première portion 4a constitue, par exemple, le deuxième élément élastiquement déformable évoqué précédemment.The first portion 4a is embedded in the second arm 5 extending from the hub 6, in particular from an internal surface 61 of the hub, in a radial or substantially radial direction relative to the axis A1. The embedding is here defined by two openings 3, 3', in particular by the portions 3a, 3b' and 3c'. More particularly, a section of the arm 4, at the level of its first portion 4a, is defined by the diameters D3a, D3b, as well as by the width L (measured radially relative to the axis A1) of the portions 3a, 3b'. The first portion 4a constitutes, for example, the second elastically deformable element mentioned previously.

La deuxième portion 4c s'étend radialement ou sensiblement radialement relativement à l'axe A1 depuis l'extrémité de la première portion 4a. Cette deuxième portion 4c est, par exemple, définie par la portion 3b' de la troisième ouverture 3' et par l'ouverture 2. La deuxième portion 4c constitue par exemple le deuxième élément de liaison 4c évoqué précédemment. La portion 4c fait office de coude.The second portion 4c extends radially or substantially radially relative to the axis A1 from the end of the first portion 4a. This second portion 4c is, for example, defined by the portion 3b' of the third opening 3' and by the opening 2. The second portion 4c constitutes for example the second connecting element 4c mentioned above. Portion 4c acts as an elbow.

La troisième portion 4b s'étend orthoradialement ou sensiblement orthoradialement relativement à l'axe A1 depuis l'extrémité de la deuxième portion 4c. Cette troisième portion 4b est, par exemple, définie par la portion 3b' de la troisième ouverture 3' et par l'ouverture 1. La troisième portion 4b constitue, par exemple, l'élément de réception 4b évoqué précédemment. La section du bras 4, au niveau de sa troisième portion 4b, est définie par les diamètres D3b et D1, ainsi que par la largeur L de la portion 3b (mesurée radialement).The third portion 4b extends orthoradially or substantially orthoradially relative to the axis A1 from the end of the second portion 4c. This third portion 4b is, for example, defined by the portion 3b' of the third opening 3' and by the opening 1. The third portion 4b constitutes, for example, the receiving element 4b mentioned above. The section of arm 4, at the level of its third portion 4b, is defined by the diameters D3b and D1, as well as by the width L of the portion 3b (measured radially).

La quatrième portion 4d s'étend radialement ou sensiblement radialement relativement à l'axe A1 depuis une extrémité de la troisième portion 4b. Cette quatrième portion 4d est, par exemple, définie par la portion 3c' de la troisième ouverture et par l'ouverture 2'. La quatrième portion 4d constitue, par exemple, le premier élément de liaison 4d évoqué précédemment.The fourth portion 4d extends radially or substantially radially relative to the axis A1 from one end of the third portion 4b. This fourth portion 4d is, for example, defined by the portion 3c' of the third opening and by the opening 2'. The fourth portion 4d constitutes, for example, the first 4d connecting element mentioned previously.

Avantageusement, la quatrième portion 4d rejoint la première portion 4a' d'un bras adjacent 4'. Avantageusement encore, cette première portion 4a' de bras adjacent 4' constitue le premier élément élastiquement déformable 4a' évoqué précédemment. Ainsi, dans cette configuration privilégiée, un même élément élastiquement déformable 4a constitue le premier élément élastiquement déformable et le deuxième élément élastiquement déformable de deux structures de réception adjacentes.Advantageously, the fourth portion 4d joins the first portion 4a' of an adjacent arm 4'. Advantageously again, this first portion 4a' of adjacent arm 4' constitutes the first elastically deformable element 4a' mentioned previously. Thus, in this preferred configuration, the same elastically deformable element 4a constitutes the first elastically deformable element and the second elastically deformable element of two adjacent receiving structures.

Lors de l'assemblage de l'organe 20, les éléments de réception 4b, 4b' et 4b" sont prévus pour être déplacés relativement à l'axe A1. Pour ce faire, l'arbre de l'organe 20 comprend une portion 20a dont le format, notamment le diamètre D20a, est supérieur au format, notamment au diamètre D1 de la première ouverture 1. Ainsi, l'insertion de la portion 20a dans l'ouverture 1 induit un déplacement des zones d'appui relativement à l'axe A1. Plus particulièrement, le fléchissement des bras élastiques 4, 4', 4" combiné à l'expansion des deuxièmes ouvertures 2, 2', 2" induit avantageusement des déplacements des éléments de réception dans des directions radiales et orthoradiales en regard de l'axe A1, et ce sans déformation du reste du composant horloger 100, en particulier sans déformation du moyeu 6.When assembling the member 20, the receiving elements 4b, 4b' and 4b" are designed to be moved relative to the axis A1. To do this, the shaft of the member 20 comprises a portion 20a whose format, in particular the diameter D20a, is greater than the format, in particular the diameter D1 of the first opening 1. Thus, the insertion of the portion 20a in the opening 1 induces a movement of the support zones relative to the axis A1. More particularly, the bending of the elastic arms 4, 4', 4" combined with the expansion of the second openings 2, 2', 2" advantageously induces movements of the receiving elements in radial and orthoradial directions facing the axis A1, and this without deformation of the rest of the watch component 100, in particular without deformation of the hub 6.

Avantageusement, les forces de serrage de l'axe 20 sont principalement données par la géométrie des deuxièmes ouvertures 2, 2', tandis que les contraintes appliquées sur le moyeu 6 sont minimisées par la conformation du premier bras 4, et donc des géométries des deux troisièmes ouvertures 3, 3'.Advantageously, the clamping forces of the axis 20 are mainly given by the geometry of the second openings 2, 2', while the stresses applied to the hub 6 are minimized by the conformation of the first arm 4, and therefore the geometries of the two third openings 3, 3'.

Dans le premier mode de réalisation illustré par les figures 1 à 4, l'ensemble des structures de réception 10 présente une symétrie d'ordre 3 relativement à l'axe A1. Ainsi, l'ensemble des structures de réception 10 comprend trois deuxièmes ouvertures 2, 2', 2" et trois premiers bras 4, 4', 4" équi-répartis autour de l'axe géométrique A1.In the first embodiment illustrated by the figures 1 to 4 , all of the reception structures 10 have order symmetry 3 relative to axis A1. Thus, all of the receiving structures 10 comprise three second openings 2, 2', 2" and three first arms 4, 4', 4" equi-distributed around the geometric axis A1.

Un tel agencement permet de maximiser le nombre de bras élastiques tout en minimisant leur raideur, et donc de minimiser les contraintes au sein du matériau constitutif des bras pour une géométrie donnée d'ouverture. Un tel agencement permet donc de minimiser les contraintes au sein des structures de réception 10 pour une force de serrage donnée de l'arbre de l'organe 20.Such an arrangement makes it possible to maximize the number of elastic arms while minimizing their stiffness, and therefore to minimize the stresses within the material constituting the arms for a given opening geometry. Such an arrangement therefore makes it possible to minimize the stresses within the receiving structures 10 for a given clamping force of the shaft of the member 20.

Les figures 4A, 4B et 4C illustrent la répartition des contraintes au sein des structures de réception 10 lors des étapes d'assemblage de l'organe 20 au sein du composant horloger 100. La figure 4A représente le composant horloger à l'état de repos c'est-à-dire non-sollicité par le contact du composant horloger. L'entier des structures 10 est ici de couleur noire, qui illustre un niveau de contraintes nul au sein du matériau constitutif des structures 10.THE Figures 4A, 4B and 4C illustrate the distribution of stresses within the receiving structures 10 during the assembly steps of the member 20 within the watch component 100. figure 4A represents the watch component in the rest state, that is to say not requested by the contact of the watch component. The entire structure 10 is here colored black, which illustrates a zero level of stress within the material constituting the structures 10.

La figure 4B illustre un état d'assemblage intermédiaire dans lequel une portion de composant horloger 20 vient en contact avec les éléments de réception 4b, 4b" et 4b" et vient les déplacer dans des directions radiales et orthoradiales en regard de l'axe A1 sous l'effet d'un accroissement du diamètre D20 jusqu'au diamètre D20a au fil de l'introduction de l'arbre 20 dans l'ouverture 1. Le maillage de couleur blanche exprime des niveaux de contraintes induits par l'expansion des trois deuxièmes ouvertures 2, 2', 2" et par le fléchissement des trois bras 4, 4', 4". On remarque que le niveau de contraintes au sein du moyeu 6 n'est pas impacté par la déformation élastique des ouvertures 2, 2', 2" et de celle des bras 4, 4', 4".There Figure 4B illustrates an intermediate assembly state in which a portion of watch component 20 comes into contact with the receiving elements 4b, 4b" and 4b" and moves them in radial and orthoradial directions facing the axis A1 under the effect of an increase in diameter D20 to diameter D20a as the shaft 20 is introduced into opening 1. The white mesh expresses stress levels induced by the expansion of the three second openings 2 , 2', 2" and by the bending of the three arms 4, 4', 4". We note that the level of stress within the hub 6 is not impacted by the elastic deformation of the openings 2, 2', 2" and that of the arms 4, 4', 4".

La figure 4C illustre le composant horloger 100 une fois l'organe 20 complètement inséré en son sein. On observe que, malgré une propagation des contraintes au sein des bras 4, le moyeu 6 n'est pas ou très peu impacté. Il s'ensuit que le moyeu n'est pas déformé. La périphérie ou serge de la roue n'est a fortiori pas déformée.There Figure 4C illustrates the watch component 100 once the member 20 is completely inserted within it. We observe that, despite a propagation of stresses within the arms 4, the hub 6 is not or very little impacted. It follows that the hub is not deformed. The periphery or rim of the wheel is a fortiori not deformed.

Les structures 10 permettent ainsi un assemblage de l'organe 20 au sein du composant 100, sans déformation parasite du moyeu, de bras, ou encore de la serge du composant.The structures 10 thus allow assembly of the member 20 within the component 100, without parasitic deformation of the hub, arm, or even the serge of the component.

Un deuxième mode de réalisation d'une pièce d'horlogerie 400 selon l'invention est décrit ci-après en référence à la figure 5. La pièce d'horlogerie est par exemple une montre, comme une montre-bracelet.A second embodiment of a timepiece 400 according to the invention is described below with reference to the figure 5 . The timepiece is for example a watch, such as a wristwatch.

La pièce d'horlogerie comprend un mouvement horloger 300. Le mouvement horloger peut être mécanique, notamment automatique.

Dans ce deuxième mode de réalisation, la pièce d'horlogerie ou le composant horloger ne diffère, par exemple, de la pièce d'horlogerie du premier mode ou du composant horloger du premier mode de préférence que par le fait que le composant horloger ne présente que deux structures de réception.In this second embodiment, the timepiece or the watch component only differs, for example, from the timepiece of the first mode or from the watch component of the first mode preferably only in that the watch component does not present only two reception structures.

De préférence, l'ensemble formé par les deux structures de réception présente une symétrie de révolution d'ordre 2.Preferably, the assembly formed by the two receiving structures has a revolution symmetry of order 2.

Par ailleurs, dans ce deuxième mode de réalisation, le composant horloger peut être dépourvu de deuxième bras 5. Dans ce cas, les premiers bras 4 peuvent être directement liés mécaniquement au moyeu 6.Furthermore, in this second embodiment, the watch component may be without a second arm 5. In this case, the first arms 4 can be directly mechanically linked to the hub 6.

Un troisième mode de réalisation d'une pièce d'horlogerie 400 selon l'invention est décrit ci-après en référence à la figure 6. La pièce d'horlogerie est par exemple une montre, comme une montre-bracelet.A third embodiment of a timepiece 400 according to the invention is described below with reference to the Figure 6 . The timepiece is for example a watch, such as a wristwatch.

La pièce d'horlogerie comprend un mouvement horloger 300. Le mouvement horloger peut être mécanique, notamment automatique. Le mouvement peut alternativement être électronique.The timepiece includes a watch movement 300. The watch movement can be mechanical, in particular automatic. The movement can alternatively be electronic.

Le mouvement comprend un ensemble 200 incluant un organe horloger 20 et un troisième mode de réalisation de composant horloger 100, l'organe horloger 20 étant monté, en particulier chassé, dans le composant horloger 100.The movement comprises an assembly 200 including a watch member 20 and a third embodiment of a watch component 100, the watch member 20 being mounted, in particular driven, in the watch component 100.

Dans ce troisième mode de réalisation, la pièce d'horlogerie ou le composant horloger ne diffère par exemple de la pièce d'horlogerie du premier mode ou du composant horloger du premier mode de préférence que par le fait que le composant horloger présente quatre structures de réception.In this third embodiment, the timepiece or the watch component differs for example from the timepiece of the first mode or from the watch component of the first mode preferably only in the fact that the watch component has four structures of reception.

De préférence, l'ensemble formé par les quatre structures de réception présente une symétrie de révolution d'ordre 4.Preferably, the assembly formed by the four receiving structures has a revolution symmetry of order 4.

En outre, dans ce troisième mode de réalisation, la pièce d'horlogerie ou le composant horloger diffère des pièces d'horlogerie des premier mode et deuxième mode ou des composants horlogers des premier mode et deuxième mode par le fait que les troisièmes ouvertures sont dédoublées.Furthermore, in this third embodiment, the timepiece or the watch component differs from the timepieces of the first mode and second mode or from the watch components of the first mode and second mode in that the third openings are split. .

Dans ce troisième mode de réalisation, un élément de structure de réception qui est similaire ou qui assure la même fonction qu'un élément de la structure de réception du premier mode de réalisation ou du deuxième mode de réalisation est identifié par la même référence numérique à laquelle est ajouté un « 1 » initial.In this third embodiment, a receiving structure element which is similar or which provides the same function as an element of the receiving structure of the first embodiment or the second embodiment is identified by the same numerical reference to to which an initial “1” is added.

Chaque structure de réception 110 comprend un premier bras élastique 14 comprenant une première portion 14a qui est encastrée dans un deuxième bras 15 s'étendant, depuis un moyeu 16, selon une direction sensiblement radiale relativement à l'axe 1A1 de la première ouverture 11. L'encastrement est ici défini par deux troisièmes ouvertures 13a, 13b' s'étendant chacune au moins partiellement orthoradialement relativement à l'axe 1A1. Plus particulièrement, l'encastrement est ici défini par des portions 113a, 113b' respectives des ouvertures 13a, 13b' s'étendant chacune orthoradialement relativement à l'axe 1A1. Une section du bras 14, au niveau de sa première portion 14a, est définie par les diamètres D13a, D13b, ainsi que par la largeur L (mesurée radialement à l'axe 1A1) des portions 113a, 113b'. Par ailleurs, des portions 113b' et 213b' d'une troisième ouverture 13b' permettent de définir, en conjonction avec les première et deuxième ouvertures 11 et 12', des portions 14b, 14c et 14d de bras 14. Le bras 14 présente ainsi une forme de bras coudé.Each receiving structure 110 comprises a first elastic arm 14 comprising a first portion 14a which is embedded in a second arm 15 extending, from a hub 16, in a substantially radial direction relative to the axis 1A1 of the first opening 11. The embedding is here defined by two third openings 13a, 13b' each extending at least partially orthoradially relative to the axis 1A1. More particularly, the embedding is here defined by respective portions 113a, 113b' of the openings 13a, 13b' each extending orthoradially relative to the axis 1A1. A section of the arm 14, at its first portion 14a, is defined by the diameters D13a, D13b, as well as by the width L (measured radially to the axis 1A1) of the portions 113a, 113b'. Furthermore, portions 113b' and 213b' of a third opening 13b' make it possible to define, in conjunction with the first and second openings 11 and 12', portions 14b, 14c and 14d of arm 14. The arm 14 thus presents a shape of an elbow arm.

Dans ce troisième mode de réalisation illustré par la figure 6, l'ensemble des structures de réception 110 présentant une symétrie de rotation d'ordre 4 relativement à l'axe 1A1, les quatre premiers bras 14, 14', 14", 14* sont équi-répartis autour de l'axe géométrique 1A1. Les portions 14a, 14a', 14a", 14a* sont respectivement encastrées dans des deuxièmes bras 15, 15', 15", 15*. Dans ce mode de réalisation, les portions 14b, 14b', 14b", 14b* respectives des bras 14, 14', 14", 14* sont respectivement encastrées dans les portions 14a, 14a', 14a", 14a* respectives des bras 14, 14', 14", 14*, via les portions 14c 14c', 14c" et 14c*. Autrement dit, les bras sont imbriqués les uns dans les autres.In this third embodiment illustrated by the Figure 6 , all of the receiving structures 110 having a rotational symmetry of order 4 relative to the axis 1A1, the first four arms 14, 14', 14", 14* are equi-distributed around the geometric axis 1A1 The portions 14a, 14a', 14a", 14a* are respectively embedded in second arms 15, 15', 15", 15*. In this embodiment, the respective portions 14b, 14b', 14b", 14b* arms 14, 14', 14", 14* are respectively embedded in the respective portions 14a, 14a', 14a", 14a* of the arms 14, 14', 14", 14*, via portions 14c 14c', 14c" and 14c*. In other words, the arms are interlocked with each other.

Quel que soit le mode de réalisation ou la variante de réalisation, le composant peut comprendre deux, trois ou quatre structures de réception de l'organe et/ou les structures de réception constituent un ensemble ayant une symétrie de rotation d'ordre N, avec N=2 ou N=3 ou N=4.Whatever the embodiment or the alternative embodiment, the component may comprise two, three or four structures for receiving the member and/or the receiving structures constitute an assembly having a rotational symmetry of order N, with N=2 or N=3 or N=4.

Quel que soit le mode de réalisation ou la variante de réalisation, le composant horloger est de préférence conformé de sorte que, lorsque l'organe est introduit dans la première ouverture, les éléments élastiquement déformables sont principalement sollicités en flexion et/ou les éléments de liaison sont principalement sollicités en compression et/ou les éléments de réception sont principalement sollicités en flexion.Whatever the embodiment or variant of embodiment, the watch component is preferably shaped so that, when the member is introduced into the first opening, the elastically deformable elements are mainly stressed in bending and/or the elements of connection are mainly stressed in compression and/or the receiving elements are mainly stressed in bending.

Quel que soit le mode de réalisation ou la variante de réalisation, un premier cylindre de révolution d'un premier diamètre est inscrit dans la première ouverture et les deuxièmes ouvertures sont inscrites dans un deuxième cylindre de révolution d'un deuxième diamètre, le deuxième diamètre pouvant valoir entre 1,1 fois et 2,5 fois le premier diamètre.Whatever the embodiment or variant of embodiment, a first cylinder of revolution of a first diameter is inscribed in the first opening and the second openings are inscribed in a second cylinder of revolution of a second diameter, the second diameter which can be between 1.1 times and 2.5 times the first diameter.

Quel que soit le mode de réalisation ou la variante de réalisation, la première ouverture est inscrite dans un premier cylindre de révolution d'un premier diamètre et les deuxièmes ouvertures sont inscrites dans un deuxième cylindre de révolution d'un deuxième diamètre, le deuxième diamètre valant entre 1,1 fois et 2,5 fois le premier diamètre.Whatever the embodiment or variant of embodiment, the first opening is inscribed in a first cylinder of revolution of a first diameter and the second openings are inscribed in a second cylinder of revolution of a second diameter, the second diameter worth between 1.1 times and 2.5 times the first diameter.

Quel que soit le mode de réalisation ou la variante de réalisation, le composant horloger peut être réalisé par un procédé d'électroformage ou un procédé de type LIGA ou un procédé de photolithographie et de gravure profonde.Whatever the embodiment or variant of embodiment, the watch component can be produced by an electroforming process or a LIGA type process or a photolithography and deep engraving process.

Quel que soit le mode de réalisation ou la variante de réalisation, le composant horloger peut être réalisé en un matériau fragile ou en Ni ou en NiP ou en Si ou en diamant ou en quartz.Whatever the embodiment or variant of embodiment, the watch component can be made of a fragile material or of Ni or of NiP or of Si or of diamond or quartz.

Quel que soit le mode de réalisation ou la variante de réalisation, le composant horloger peut comprendre un moyeu 6 dont le diamètre extérieur est inférieur à 2 mm ou inférieur à 1.5 mm ou inférieur à 1.2 mm, les structures de réception étant liées mécaniquement au moyeu, à l'intérieur du moyeu, c'est-à-dire liées à une surface tournée vers l'intérieur du moyeu.Whatever the embodiment or variant of embodiment, the watch component may comprise a hub 6 whose external diameter is less than 2 mm or less than 1.5 mm or less than 1.2 mm, the receiving structures being mechanically linked to the hub , inside the hub, that is to say linked to a surface facing the inside of the hub.

Pour les différents modes de réalisation, les sections des structures sont représentées. De préférence, ces sections peuvent être identiques et orientées de la même façon dans tous les différents plans de coupes perpendiculaires à l'axe A1, 1A1. Toutefois, ces sections peuvent aussi évoluer le long de l'axe A1, 1A1. Notamment, les sections peuvent tourner le long de l'axe A1, 1A1 et des formes hélicoïdales peuvent ainsi être réalisées.For the different embodiments, the sections of the structures are represented. Preferably, these sections can be identical and oriented in the same way in all the different section planes perpendicular to the axis A1, 1A1. However, these sections can also evolve along the A1, 1A1 axis. In particular, the sections can rotate along the axis A1, 1A1 and helical shapes can thus be produced.

Les solutions de composants horlogers décrites précédemment présentent donc des structures élastiques, prévues pour réceptionner un organe, comme un axe. Ces structures présentent la spécificité d'être particulièrement compactes. Elles peuvent, par exemple, être disposées au centre d'un composant horloger, notamment d'une roue, et être supportées par un moyeu de faible diamètre.The watch component solutions described above therefore have elastic structures, designed to accommodate an organ, such as an axis. These structures have the specificity of being particularly compact. They can, for example, be placed in the center of a watch component, in particular a wheel, and be supported by a small diameter hub.

En outre, de telles structures permettent avantageusement de ne pas induire, lors du chassage de l'organe, de déformation de la géométrie externe du composant horloger, comme la serge, ni de déformation des bras reliant le moyeu à la serge. Par ailleurs, les structures, de par leur compacité, n'ont aucun effet sur l'esthétique ou la géométrie de la majeure partie de l'organe, notamment de la planche de roue. En particulier, les structures n'ont aucun effet sur l'esthétique ou la géométrie de bras reliant un moyeu à une serge de roue. Ainsi, de telles structures peuvent avantageusement être implémentées au sein d'un composant, en particulier d'une roue, au design prédéfini.In addition, such structures advantageously make it possible not to induce, when driving out the member, any deformation of the external geometry of the watch component, such as the serge, nor any deformation of the arms connecting the hub to the serge. Furthermore, the structures, due to their compactness, have no effect on the aesthetics or geometry of the majority of the organ, in particular of the wheel plate. In particular, the structures have no effect on the aesthetics or geometry of the arm connecting a hub to a wheel rim. Thus, such structures can advantageously be implemented within a component, in particular a wheel, with a predefined design.

Les composants décrits précédemment sont particulièrement adaptés aux matériaux qui ne comportent pas ou peu de domaine de déformation plastique.The components described above are particularly suitable for materials which have little or no area of plastic deformation.

Les composants décrits sont en particulier conformés afin de minimiser sensiblement, voire d'annuler, toute déformation du reste du composant horloger lorsqu'un organe est chassé dans le composant. En pratique, de tels composants permettent, par exemple, un assemblage robuste, fiable, et pérenne d'une roue d'échappement sur un axe, et ce indépendamment de toute déformation des bras ou du pourtour extérieur, notamment de la denture, de ladite roue risquant d'engendrer un mal-rond.The components described are in particular shaped in order to significantly minimize, or even eliminate, any deformation of the rest of the watch component when a member is driven into the component. In practice, such components allow, for example, a robust, reliable and durable assembly of an escape wheel on an axis, independently of any deformation of the arms or the external periphery, in particular of the teeth, of said wheel which could cause a mis-round.

Par ailleurs, les structures de réception de tels composants ont pour avantage d'être particulièrement compactes et de s'intégrer ainsi aisément à une esthétique prédéfinie de composant horloger.Furthermore, the structures for receiving such components have the advantage of being particularly compact and thus easily integrated into a predefined aesthetic of a watch component.

Les composants horlogers décrits sont particulièrement aptes à être montés ou chassés élastiquement sur un axe, sans déformation ou quasiment sans déformation de leur pourtour due à leur montage sur un arbre.The watch components described are particularly suitable for being mounted or driven elastically on an axis, without deformation or almost without deformation of their circumference due to their mounting on a shaft.

De préférence, dans la présente demande, par « un élément s'étend selon une première direction », on entend que l'élément a une première dimension selon cette première direction qui est au moins supérieure, voire au moins deux fois supérieure, à une deuxième dimension selon une deuxième direction perpendiculaire à cette première direction, les première et deuxièmes directions étant perpendiculaires à l'axe A1, 1A1.Preferably, in the present application, by "an element extends in a first direction", it is meant that the element has a first dimension in this first direction which is at least greater, or even at least twice greater, than a second dimension in a second direction perpendicular to this first direction, the first and second directions being perpendicular to the axis A1, 1A1.

Alternativement ou complémentairement, dans la présente demande, par « un élément s'étend selon une première direction », on entend que l'élément relie mécaniquement deux éléments distants s'étendant ou s'étendant sensiblement chacun selon une deuxième direction perpendiculaire à la première direction.Alternatively or additionally, in the present application, by "an element extends in a first direction", it is meant that the element mechanically connects two distant elements extending or each extending substantially in a second direction perpendicular to the first direction.
