Description

IntroductionIntroduction

La présente invention concerne un cadran pour pièce d'horlogerie, un assemblage horloger intégrant un tel cadran coopérant avec une ébauche d'une pièce d'horlogerie. Elle concerne aussi une pièce d'horlogerie en tant que telle, intégrant un tel agencement, comme une montre-bracelet.The present invention relates to a dial for a timepiece, a timepiece assembly integrating such a dial cooperating with a blank of a timepiece. It also relates to a timepiece as such, incorporating such an arrangement, such as a wristwatch.

Etat de l'ArtState of the art

Une première solution de l'état de la technique pour la fixation d'un cadran de montre sur un bâti requiert des goupilles faisant saillie sous la surface inférieure du cadran. Ces goupilles viennent se loger dans des découpes agencées sur la surface supérieure du bâti. Des vis disposées au sein du bâti sont utilisées pour venir en appui contre les goupilles et les bloquer, pour empêcher toute dissociation du cadran et du bâti. Cette fixation présente un premier inconvénient de ne pas être conviviale et fiable puisqu'il faut manipuler plusieurs vis de petite dimension. Elle présente un second inconvénient d'être encombrante et de ce fait non implémentable sur des montres dotées de multiples fonctions, qui nécessitent l'occupation d'une grande partie de la surface disponible, comme dans le cas d'une montre calendrier, sauf en augmentant fortement le diamètre global de la montre au détriment de l'aspect esthétique. Enfin, un autre inconvénient de cette solution est qu'elle risque de générer une situation d'hyperstatisme dès lors qu'une précision parfaite des éléments participant à la fixation n'est pas atteinte.A first prior art solution for fixing a watch dial to a frame requires pins projecting below the lower surface of the dial. These pins are housed in cutouts arranged on the upper surface of the frame. Screws arranged within the frame are used to bear against the pins and block them, to prevent any dissociation of the dial and the frame. This fixing has a first drawback of not being user-friendly and reliable since it is necessary to handle several small screws. It has a second drawback of being cumbersome and therefore cannot be implemented on watches equipped with multiple functions, which require the occupation of a large part of the available surface, as in the case of a calendar watch, except in greatly increasing the overall diameter of the watch to the detriment of the aesthetic aspect. Finally, another drawback of this solution is that it risks generating a situation of hyperstatism when perfect precision of the elements participating in the fixing is not achieved.

Le document CH353310 divulgue une solution différente de la précédente dans laquelle les goupilles sont remplacées par des saillies élastiques qui s'engagent dans des découpes d'une platine de montre. Cette solution évite l'utilisation des vis de la solution précédente, mais conserve les autres inconvénients. Elle repose de plus sur des éléments à géométrie complexe.The document CH353310 discloses a solution different from the previous one in which the pins are replaced by elastic projections which engage in cutouts of a watch plate. This solution avoids the use of the screws of the previous solution, but retains the other disadvantages. It is also based on elements with complex geometry.

Une autre solution, décrite par le document GB2079497 , permet de simplifier les éléments de liaison, en disposant de simples bras élastiques sur le pourtour d'un cadran plat, qui coopèrent avec des tenons rapportés sur la face supérieure du bâti de la pièce d'horlogerie. Cette solution exige toutefois une surface importante, notamment pour pouvoir disposer ces bras élastiques. L'utilisation de tenons est de plus complexe puisque ces derniers doivent être pré-assemblés avant le montage du cadran.Another solution, described by the document GB2079497 , makes it possible to simplify the connecting elements, by arranging simple elastic arms on the periphery of a flat dial, which cooperate with studs attached to the upper face of the frame of the timepiece. However, this solution requires a large surface area, in particular to be able to arrange these elastic arms. The use of tenons is more complex since they must be pre-assembled before mounting the dial.

Le document CH282448 décrit une autre approche de fixation d'un cadran qui est doté d'une plaque de cadran et d'une jupe annulaire. Cette dernière vient recouvrir une surface latérale du bâti, ce qui lui permet de solidariser le cadran au bâti par des vis ou des goupilles. Cette solution reste peu conviviale puisqu'elle nécessite des opérations de vissage et des éléments de fixation externes.The document CH282448 describes another approach to attaching a dial that has a dial plate and an annular skirt. The latter comes to cover a side surface of the frame, which allows it to secure the dial to the frame by screws or pins. This solution remains not very user-friendly since it requires screwing operations and external fastening elements.

Le document FR2077399 décrit enfin une autre solution, dans laquelle un cadran comprend une plaque de cadran et des pattes élastiques sur sa périphérie, qui s'étendent vers le bas. Ces pattes élastiques coopèrent avec un anneau de fixation lié au bâti. Elles sont mobiles élastiquement autour de leur axe de liaison horizontal avec la plaque de cadran, disposé vers leur extrémité supérieure. Lors de la fixation du cadran, ces pattes s'écartent élastiquement vers l'extérieur du cadran autour de leur axe de liaison pour venir loger une partie inférieure sous l'anneau de fixation. L'axe de liaison de ces pattes étant orienté dans une direction parallèle à la plaque de cadran, la longueur active des pattes est limitée à la hauteur totale du cadran. Cette géométrie est mal adaptée à un nombre important d'opérations de montages/démontages et ne permet pas de garantir une fiabilité durable de la fixation.The document FR2077399 finally describes another solution, in which a dial comprises a dial plate and elastic tabs on its periphery, which extend downwards. These elastic tabs cooperate with a fixing ring linked to the frame. They are elastically movable around their horizontal connecting axis with the dial plate, arranged towards their upper end. When fixing the dial, these lugs deviate elastically towards the outside of the dial around their connecting axis to accommodate a lower part under the fixing ring. The connecting axis of these lugs being oriented in a direction parallel to the dial plate, the active length of the lugs is limited to the total height of the dial. This geometry is poorly suited to a large number of operations of assembly/disassembly and does not make it possible to guarantee the lasting reliability of the binding.

Les documents FR 1 003 696 , CH 316 203 A , FR 1 260 354 A et US 2 039 672 A divulguent également des cadrans pour des pièces d'horlogerie.The documents FR 1 003 696 , CH 316 203 A , FR 1 260 354 A and US 2,039,672 A also disclose dials for timepieces.

Finalement, toutes les solutions existantes ne permettent pas d'atteindre un résultat satisfaisant et l'objet général de l'invention est de proposer une solution de fixation d'un cadran de pièce d'horlogerie sur une ébauche de pièce d'horlogerie, comme un bâti de montre par exemple, qui permet d'atteindre un compromis optimal entre sa simplicité et convivialité de manipulation, son faible encombrement, sa fiabilité, et son aspect esthétique.Finally, all the existing solutions do not make it possible to achieve a satisfactory result and the general object of the invention is to propose a solution for fixing a timepiece dial to a timepiece blank, such as a watch frame, for example, which makes it possible to achieve an optimal compromise between its simplicity and user-friendliness of handling, its small size, its reliability, and its aesthetic appearance.

Brève description de l'inventionBrief description of the invention

A cet effet, l'invention repose sur un cadran pour pièce d'horlogerie, muni d'une jupe qui comprend au moins un élément élastique qui s'étend partiellement sur la hauteur de la jupe et est apte à remplir la fonction de maintien axial du cadran sur une ébauche de pièce d'horlogerie.To this end, the invention is based on a dial for a timepiece, provided with a skirt which comprises at least one elastic element which extends partially over the height of the skirt and is capable of fulfilling the function of axial support of the dial on a blank timepiece.

Les figures 1, 3 et 4 représentent deux composants d'un assemblage horloger selon un mode de réalisation de l'invention. D'abord, un cadran 1 comprend une plaque 2 en forme de disque et une jupe 3 qui s'étend dans une direction sensiblement perpendiculaire à la plaque sur la circonférence de cette dernière. Ce cadran 1 est destiné à venir coopérer avec une ébauche 20 d'une pièce d'horlogerie, comme un bâti de montre, qui présente aussi globalement une forme de disque. La figure 1 représente le cadran 1 en vis-à-vis avec une ébauche 20, non fixé à cette dernière.The figure 1 , 3 and 4 represent two components of a timepiece assembly according to one embodiment of the invention. First, a dial 1 comprises a disc-shaped plate 2 and a skirt 3 which extends in a direction substantially perpendicular to the plate on the circumference of the latter. This dial 1 is intended to cooperate with a blank 20 of a timepiece, such as a watch frame, which also generally has the shape of a disk. The figure 1 represents the dial 1 vis-à-vis with a blank 20, not attached to the latter.

Par convention, nous choisissons de définir la direction horizontale par un plan parallèle à la plaque 2 du cadran, et la direction verticale z comme la direction qui lui est perpendiculaire, orientée de l'ébauche vers le cadran. Avec cette convention, qui permet de simplifier la description suivante, la jupe 3 s'étend donc verticalement vers le bas depuis la plaque 2 du cadran, et la fixation du cadran 1 sur l'ébauche 20 se fait par un rapprochement vertical du cadran au-dessus de l'ébauche. Cette direction verticale de fixation des deux composants sera aussi appelée direction axiale par la suite, pour faire référence à l'axe des disques formant les deux composants de l'assemblage. En complément, la direction tangentielle fera référence à toute direction tangente à un cercle centré sur un axe selon la direction axiale, notamment l'axe des disques formant les deux composants de l'assemblage. L'homme du métier comprendra que ces termes ainsi définis peuvent être utilisés quelle que soit la forme du cadran et/ou de l'ébauche, non nécessairement circulaire.By convention, we choose to define the horizontal direction by a plane parallel to plate 2 of the dial, and the vertical direction z as the direction which is perpendicular to it, oriented from the blank towards the dial. With this convention, which makes it possible to simplify the following description, the skirt 3 therefore extends vertically downwards from the plate 2 of the dial, and the fixing of the dial 1 on the blank 20 is done by a vertical approximation of the dial to the above the blank. This vertical direction of attachment of the two components will also be called axial direction hereafter, to refer to the axis of the discs forming the two components of the assembly. In addition, the tangential direction will refer to any direction tangent to a circle centered on an axis along the axial direction, in particular the axis of the discs forming the two components of the assembly. A person skilled in the art will understand that these terms thus defined can be used whatever the shape of the dial and/or of the blank, which is not necessarily circular.

Le cadran 1 selon le mode de réalisation de l'invention comprend sur sa jupe 3 des éléments élastiques 10, se présentant sous forme de lames élastiques orientées tangentiellement relativement à un axe selon la direction axiale, formées par de simples fentes 11 traversantes réalisées dans la jupe 3. Ces éléments élastiques 10 ont pour fonction de réaliser la fixation axiale du cadran sur une ébauche, comme cela sera détaillé par la suite. Dans l'exemple illustré, la jupe comprend trois lames élastiques équiréparties sur son contour circulaire, soit tous les 120 degrés. La jupe comprend aussi des découpes 5 s'étendant sur une partie importante de sa hauteur, dont une fonction est d'assurer un indexage angulaire du cadran sur l'ébauche.The dial 1 according to the embodiment of the invention comprises on its skirt 3 elastic elements 10, in the form of elastic blades oriented tangentially relative to an axis in the axial direction, formed by simple through slots 11 made in the skirt 3. These elastic elements 10 have the function of carrying out the axial fixing of the dial on a blank, as will be detailed below. In the example illustrated, the skirt comprises three elastic blades evenly distributed over its circular contour, ie every 120 degrees. The skirt also includes cutouts 5 extending over a significant part of its height, one function of which is to provide angular indexing of the dial on the blank.

L'ébauche 20 comprend des éléments complémentaires aptes à coopérer avec les éléments élastiques 10 et les découpes 5 de la jupe 3 du cadran. Ainsi, l'ébauche 20 se présente sous la forme d'un disque de diamètre légèrement inférieur à celui du cadran, de sorte que la jupe 3 du cadran vient recouvrir son contour extérieur en positionnant la plaque 2 du cadran sur l'ébauche 20. Cette dernière comprend aussi au niveau de la surface latérale formant son contour externe des premières protubérances 30, qui font saillie sur cette surface et sont destinées à coopérer avec les éléments élastiques 10 du cadran, et éventuellement des secondes protubérances 25, qui font de même saillie et sont prévues pour coopérer avec les découpes 5 de la jupe. Ces protubérances sont disposées à une hauteur et selon une répartition angulaire définies en fonction de la géométrie de la jupe du cadran.The blank 20 comprises complementary elements capable of cooperating with the elastic elements 10 and the cutouts 5 of the skirt 3 of the dial. Thus, the blank 20 is in the form of a disc with a diameter slightly smaller than that of the dial, so that the skirt 3 of the dial comes to cover its outer contour by positioning the plate 2 of the dial on the blank 20. The latter also comprises, at the level of the lateral surface forming its outer contour, first protrusions 30, which protrude from this surface and are intended to cooperate with the elastic elements 10 of the dial, and possibly second protuberances 25, which protrude in the same way. and are provided to cooperate with the cutouts 5 of the skirt. These protuberances are arranged at a height and according to an angular distribution defined according to the geometry of the skirt of the dial.

Les figures 5 et 6 illustrent plus précisément le fonctionnement de la solution selon ce mode de réalisation.The figures 5 and 6 more precisely illustrate the operation of the solution according to this embodiment.

La figure 5 représente le cadran 1 en phase d'approche au dessus de l'ébauche 20. L'extrémité inférieure 12 d'un élément élastique 10 de la jupe 3 vient en contact avec la surface supérieure d'une protubérance 30 du contour de l'ébauche 20. Pour faciliter le positionnement relatif des deux composants, une surface en forme de cône d'entrée ou chanfrein 13 est formée au niveau de la surface intérieure de la jupe, c'est-à-dire orientée vers l'ébauche 20, vers cette extrémité inférieure de la lame. Cette surface en forme de cône d'entrée ou chanfrein 13 vient en contact avec un contour arrondi ou chanfreiné de l'angle extérieur de la surface supérieure 33 de la protubérance 30 de l'ébauche 20. Ces deux surfaces en contact présentent une géométrie qui favorise le déplacement et la déformation de la lame contre la protubérance 30.The figure 5 represents the dial 1 in the approach phase above the blank 20. The lower end 12 of an elastic element 10 of the skirt 3 comes into contact with the upper surface of a protuberance 30 of the outline of the blank 20. To facilitate the relative positioning of the two components, a surface in the form of an entry cone or chamfer 13 is formed at the level of the inner surface of the skirt, that is to say oriented towards the blank 20, towards this lower end of the blade. This surface in the form of an entry cone or chamfer 13 comes into contact with a rounded or chamfered contour of the exterior angle of the upper surface 33 of the protuberance 30 of the blank 20. These two surfaces in contact have a geometry which favors the displacement and the deformation of the blade against the protuberance 30.

Lorsque le cadran 1 poursuit sa descente, la lame est écartée par la protubérance 30, en se déformant élastiquement. Ce mouvement est poursuivi jusqu'à ce que la surface inférieure 7 de la plaque 2 vienne en appui sur la surface supérieure 27 de l'ébauche 20, ou en variante jusqu'à toute butée agencée entre les deux composants pour stopper ce déplacement en direction axiale. Dans ce mode de réalisation, la surface supérieure 27 de l'ébauche 20 comprend une découpe 28 pour permettre le positionnement de l'arrête inférieure et intérieure 8 de la jupe 3 au niveau de la fente 11 qui délimite l'élément élastique 10, afin de ne pas bloquer la descente de la plaque 2 jusqu'en appui sur l'ébauche 20 au niveau de la protubérance 30.When the dial 1 continues its descent, the blade is pushed aside by the protuberance 30, deforming elastically. This movement is continued until the lower surface 7 of the plate 2 comes to rest on the upper surface 27 of the blank 20, or alternatively until any stop arranged between the two components to stop this movement in the direction axial. In this embodiment, the upper surface 27 of the blank 20 comprises a cutout 28 to allow the positioning of the lower and inner edge 8 of the skirt 3 at the level of the slot 11 which delimits the elastic element 10, in order to not to block the descent of the plate 2 until it rests on the blank 20 at the level of the protuberance 30.

En position finale représentée par la figure 6, le cadran est maintenu dans sa direction axiale par l'effort élastique de rappel exercé par l'élément élastique 10 de la jupe 3 sur la protubérance 30 de l'ébauche 20. Le cadran 1 est donc maintenu par friction sur l'ébauche 20. Autrement dit, le cadran 1 est clippé sur l'ébauche 20.In the final position represented by the figure 6 , the dial is held in its axial direction by the elastic return force exerted by the elastic element 10 of the skirt 3 on the protrusion 30 of the blank 20. The dial 1 is therefore held by friction on the blank 20 In other words, dial 1 is clipped onto blank 20.

En remarque, au cours de cette phase de fixation du cadran sur l'ébauche, une phase préalable d'indexation angulaire du cadran est préférentiellement mise en œuvre pour assurer le bon positionnement relatif des deux composants, dans laquelle les éléments élastiques 10 de la jupe viennent coopérer avec les éléments correspondants de l'ébauche, c'est-à-dire les protubérances 30 dans l'exemple illustré. Pour cela, dans la position représentée par la figure 5 par exemple, le cadran est tourné relativement à l'ébauche jusqu'à ce qu'au moins une des parois latérales d'une découpe 5 vienne en butée contre une protubérance 25 correspondante. Cette indexation angulaire peut en variante être obtenue par tout autre moyen et les secondes protubérances 25 sont ici choisies à titre d'exemple.As a side note, during this phase of fixing the dial on the blank, a preliminary phase of angular indexing of the dial is preferably implemented to ensure the correct relative positioning of the two components, in which the elastic elements 10 of the skirt come to cooperate with the corresponding elements of the blank, that is to say the protuberances 30 in the example illustrated. For this, in the position represented by the figure 5 for example, the dial is turned relative to the blank until at least one of the side walls of a cutout 5 comes into abutment against a corresponding protuberance 25. That Angular indexing can alternatively be obtained by any other means and the second protuberances 25 are chosen here by way of example.

La figure 7 illustre une variante de réalisation d'un élément élastique 10 de la jupe 3 du cadran. Dans cette variante, une découpe ou fente supplémentaire 14 est formée dans la jupe 3, dans une direction sensiblement verticale et perpendiculaire à la fente 11 précédemment décrite, pour former une lame qui n'est plus encastrée (ou simplement liée) avec la jupe que par une seule extrémité 16, alors que dans la description précédente elle était encastrée sur ses deux extrémités 16.The figure 7 illustrates a variant embodiment of an elastic element 10 of the skirt 3 of the dial. In this variant, an additional cutout or slot 14 is formed in the skirt 3, in a substantially vertical direction and perpendicular to the previously described slot 11, to form a blade which is no longer embedded (or simply linked) with the skirt that by a single end 16, whereas in the previous description it was embedded on its two ends 16.

La figure 8 représente une autre variante de réalisation, dans laquelle le maintien axial du cadran est renforcé par le fait que l'élément élastique vient crocher l'ébauche. Pour cela, la protubérance 30 est modifiée pour présenter un flanc légèrement incliné, par exemple de l'ordre de 5 degrés, dans lequel est aménagé un décrochement 33 en partie supérieure, sous lequel vient se loger par effet élastique l'extrémité supérieure 15 de l'élément élastique 10 dont la géométrie est complémentaire à celle du décrochement 33, lors de la phase de fixation du cadran sur l'ébauche. Le maintien axial est alors assuré par la combinaison de l'effet de clipsage élastique de l'élément élastique et l'effet de crochet, de butée de la surface supérieure de l'élément élastique contre la face inférieure du décrochement 33. L'élément élastique est ainsi crocheté à la protubérance 30.The figure 8 represents another embodiment variant, in which the axial holding of the dial is reinforced by the fact that the elastic element engages the blank. For this, the protrusion 30 is modified to present a slightly inclined side, for example of the order of 5 degrees, in which is arranged a recess 33 in the upper part, under which is housed by elastic effect the upper end 15 of the elastic element 10 whose geometry is complementary to that of the recess 33, during the phase of fixing the dial on the blank. The axial holding is then ensured by the combination of the elastic clipping effect of the elastic element and the hook effect, of abutment of the upper surface of the elastic element against the lower face of the recess 33. The element elastic is thus hooked to the protrusion 30.

Naturellement, un grand nombre des composants du cadran et de l'ébauche pourraient se présenter différemment.Naturally, many of the components of the dial and the blank could look different.

D'abord, le nombre d'éléments élastiques de la jupe du cadran a été choisi à trois dans le mode de réalisation décrit ci-dessus. Toutefois, tout autre nombre pourrait être choisi, un seul pourrait même suffire pour assurer un maintien axial. De préférence, s'il y a plusieurs éléments élastiques, ils sont équi-répartis sur la circonférence de la jupe pour favoriser le centrage du cadran relativement à la pièce d'horlogerie, et donc favoriser le centrage du cadran relativement aux éventuels organes d'affichage. D'autre part, un élément élastique coopère avec un élément complémentaire de l'ébauche, comme une protubérance. De préférence, l'élément élastique de la jupe du cadran est centré par rapport à cet élément complémentaire de l'ébauche.First, the number of elastic elements of the skirt of the dial has been chosen to be three in the embodiment described above. However, any other number could be chosen, a single one could even suffice to ensure axial retention. Preferably, if there are several elastic elements, they are evenly distributed over the circumference of the skirt to promote the centering of the dial relative to the timepiece, and therefore to promote the centering of the dial relative to any display members. On the other hand, an elastic element cooperates with a complementary element of the blank, such as a protuberance. Preferably, the elastic element of the skirt of the dial is centered with respect to this complementary element of the blank.

Selon le mode de réalisation illustré, un élément élastique est obtenu par au moins une fente réalisée dans la jupe, comme plus particulièrement visible sur les figures 4 et 7. Une telle fente 11 peut s'étendre tangentiellement selon un secteur angulaire variant entre 10 et 30 degrés, dans le cas d'un cadran circulaire. Par ce choix, pour un cadran d'environ 15 mm de diamètre, une fente s'étendant sur un secteur angulaire de 20 degrés permet de former une lame de longueur active L de l'ordre de 5 mm. Cette longueur active L est de préférence comprise entre 3 et 10 mm. D'autre part, cette fente est positionnée pour former une lame élastique de hauteur H inférieure ou égale à 2 mm, ou inférieure ou égale à 1 mm, ou inférieure ou égale à 0,7 mm, par exemple autour de 0,5 mm, ou inférieure ou égale à 0,5 mm, ou inférieure ou égale à 0,3 mm. De plus, la jupe peut être en métal, notamment un métal élastique comme un métal cuivreux ou précieux, d'épaisseur e comprise entre 0,2 et 0,4 mm.According to the illustrated embodiment, an elastic element is obtained by at least one slit made in the skirt, as more particularly visible on the figure 4 and 7 . Such a slot 11 can extend tangentially along an angular sector varying between 10 and 30 degrees, in the case of a circular dial. By this choice, for a dial of approximately 15 mm in diameter, a slot extending over an angular sector of 20 degrees makes it possible to form a blade of active length L of the order of 5 mm. This active length L is preferably between 3 and 10 mm. On the other hand, this slot is positioned to form an elastic blade of height H less than or equal to 2 mm, or less than or equal to 1 mm, or less than or equal to 0.7 mm, for example around 0.5 mm , or less than or equal to 0.5 mm, or less than or equal to 0.3 mm. In addition, the skirt may be made of metal, in particular an elastic metal such as a cuprous or precious metal, with a thickness e of between 0.2 and 0.4 mm.

L'élément élastique a été représenté sous forme de lame élastique s'étendant tangentiellement. Naturellement, il est possible d'utiliser une lame élastique s'étendant dans une direction quelconque, de préférence avec une composante horizontale non nulle, voire avec un angle plutôt faible par rapport à la direction horizontale. Plus généralement, l'élément élastique de la jupe est avantageusement mobile autour d'au moins une extrémité 16, fixe sur la jupe et non parallèle à la plaque du cadran, c'est-à-dire non horizontale. Cette extrémité 16 peut notamment être sensiblement perpendiculaire à la plaque du cadran.The elastic element has been represented in the form of an elastic blade extending tangentially. Naturally, it is possible to use an elastic blade extending in any direction, preferably with a non-zero horizontal component, or even with a rather small angle with respect to the horizontal direction. More generally, the elastic element of the skirt is advantageously movable around at least one end 16, fixed on the skirt and not parallel to the dial plate, that is to say not horizontal. This end 16 may in particular be substantially perpendicular to the dial plate.

D'autre part, cet élément élastique est formé par l'intermédiaire d'une lame réalisée directement dans la jupe à l'aide d'au moins une fente. Cette solution présente l'avantage de la simplicité, et forme un ensemble continu, la lame étant liée à la jupe par au moins une extrémité 16 appartenant à la jupe. De préférence, cette fente est sensiblement parallèle à la plaque du cadran. En variante, une lame distincte de la jupe pourrait être rapportée et fixée sur la surface de la jupe par tout moyen. En variante encore, cet élément élastique pourrait prendre une autre forme, et ne plus se présenter comme une lame.On the other hand, this elastic element is formed by means of a strip made directly in the skirt using at least one slot. This solution has the advantage of simplicity, and forms a continuous assembly, the blade being linked to the skirt by at least one end 16 belonging to the skirt. Preferably, this slot is substantially parallel to the dial plate. Alternatively, a blade separate from the skirt could be attached and fixed to the surface of the skirt by any means. As a further variant, this elastic element could take another form, and no longer appear as a blade.

Par une telle construction, l'élément élastique ne s'étend pas sur toute la hauteur h de la jupe, mais sur une partie seulement de cette hauteur h, ce qui lui permet d'atteindre des propriétés élastiques bien adaptées à la fixation recherchée. Cette hauteur H de l'élément élastique, ou plus généralement largeur si cet élément n'est pas horizontal, peut préférentiellement représenter moins des deux tiers de la hauteur h totale de la jupe, voire moins de la moitié de cette hauteur, voire mois du tiers de la hauteur h totale de la jupe.By such a construction, the elastic element does not extend over the entire height h of the skirt, but over only part of this height h, which allows it to achieve elastic properties that are well suited to the desired attachment. This height H of the elastic element, or more generally the width if this element is not horizontal, can preferably represent less than two thirds of the total height h of the skirt, or even less than half of this height, or even the month of the third of the total height h of the skirt.

Le cadran peut aussi comprendre une surface supplémentaire destinée à venir en appui avec une surface de la boîte lors de l'assemblage de la montre, pour finalement présenter en position finale un appui sur l'ébauche et sur un autre composant, comme la carrure de la pièce d'horlogerie.The dial can also include an additional surface intended to come into contact with a surface of the case during assembly of the watch, to finally present in the final position a support on the blank and on another component, such as the middle of the case. the timepiece.

Le cadran est avantageusement réalisé en matériau cuivreux, comme un laiton par exemple. En variante, il peut être réalisé en matériau précieux, comme l'or ou le platine. En variante, tout autre matériau présentant des propriétés élastiques et/ou mécaniques adaptées à la mise en œuvre du concept décrit précédemment peut être utilisé.The dial is advantageously made of copper material, such as brass for example. Alternatively, it can be made of precious material, such as gold or platinum. As a variant, any other material having elastic and/or mechanical properties suitable for implementing the concept described above can be used.

Alternativement, l'indexage angulaire de ces composants de l'assemblage horloger peut s'effectuer par le biais d'un moyen connexe, comme une goupille par exemple, ou par tout autre moyen.Alternatively, the angular indexing of these components of the watch assembly can be carried out by means of a related means, such as a pin for example, or by any other means.

L'ébauche peut de même présenter une autre géométrie. Notamment, une première protubérance destinée à coopérer avec un élément élastique d'une jupe du cadran peut former une saillie ou surépaisseur du contour comprise entre 0,01 et 0.2 mm. Cette valeur est avantageusement choisie pour correspondre à la flèche de l'élément élastique du cadran. Chaque première et/ou seconde protubérance 30, 25 peut aussi former une surface supérieure d'appui 27, recevant une partie latérale de la surface inférieure 7 du cadran, comme cela est visible sur la coupe B-B de la figure 9.The blank can likewise have another geometry. In particular, a first protrusion intended to cooperate with an elastic element of a skirt of the dial can form a projection or extra thickness of the outline of between 0.01 and 0.2 mm. This value is advantageously chosen to correspond to the arrow of the elastic element of the dial. Each first and/or second protuberance 30, 25 can also form an upper bearing surface 27, receiving a lateral part of the lower surface 7 of the dial, as can be seen in section BB of the figure 9 .

En variante de réalisation représentée par la figure 10, la jupe du cadran comprend une surface inférieure 12 qui vient en appui sur une surface de l'ébauche.In the embodiment variant represented by the figure 10 , the skirt of the dial comprises a lower surface 12 which bears against a surface of the blank.

Enfin, le mode de réalisation décrit a présenté la forme la plus courante d'une montre circulaire, mais toute forme quelconque pour s'adapter à l'esthétique d'une pièce d'horlogerie peut convenir, comme une forme rectangulaire, ou elliptique. L'assemblage horloger décrit précédemment est adapté pour une utilisation dans diverses pièces d'horlogerie, comme une montre.Finally, the embodiment described presented the most common shape of a circular watch, but any shape to adapt to the aesthetics of a timepiece can be suitable, such as a rectangular shape, or an elliptical. The timepiece assembly described above is suitable for use in various timepieces, such as a watch.
