Description

La présente invention concerne un maillon, prévu pour relier un bracelet au boîtier d'une montre, ce dernier comportant un élément d'habillage qui définit au moins partiellement ses limites dans la direction longitudinale du bracelet, cet élément d'habillage étant obtenu par un procédé incluant une étape de frittage.The present invention relates to a link, intended to connect a bracelet to the case of a watch, the latter comprising a covering element which at least partially defines its limits in the longitudinal direction of the bracelet, this covering element being obtained by a method including a sintering step.

L'invention concerne plus généralement le domaine des bracelets de montre réalisés partiellement en matériaux durs, tel que la céramique, destinés à être assemblés sur des montres dont le boîtier comporte un habillage en matériau dur.The invention more generally relates to the field of wristwatches made partially of hard materials, such as ceramics, intended to be assembled on watches whose housing comprises a hard material covering.

Un tel type de bracelet, comportant une structure interne plus ou moins flexible assurant une fonction d'ossature et recouverte au moins partiellement d'un habillage, est connu de l'homme du métier.Such a type of bracelet, having a more or less flexible internal structure providing a framework function and at least partially covered with a covering, is known to those skilled in the art.

Le brevet américain No 5,365,753 décrit un bracelet, notamment pour montre, comportant une chaîne interne composée de maillons articulés, reliés entre eux par des charnières. Chacun de ces maillons, constitué de deux éléments structurels, est recouvert par un élément externe d'habillage réalisé en céramique. En outre, chaque maillon comporte des moyens de retenue de l'élément d'habillage correspondant de façon à obtenir un effet esthétique avantageux, dans la mesure où les différentes charnières reliant les maillons entre eux ne sont ainsi jamais apparentes.US Patent No. 5,365,753 describes a bracelet, including a watch, comprising an internal chain made of articulated links, interconnected by hinges. Each of these links, consisting of two structural elements, is covered by an external cladding element made of ceramic. In addition, each link comprises means for retaining the corresponding covering member so as to obtain an advantageous aesthetic effect, insofar as the different hinges connecting the links between them are never visible.

Cependant, cette structure présente certaines limites dans son application, de même que les bracelets de ce type connus de l'art antérieur d'une manière générale. En effet, les pièces d'habillage en matériaux durs, par exemple en céramique, sont obtenues par des procédés comportant une étape de moulage suivie d'un frittage. Au cours du frittage ces pièces subissent une contraction, c'est-à-dire une réduction importante de leur volume, sous les actions combinées de la chaleur et de la pression, cette contraction pouvant représenter plus de 30% du volume initial. Les procédés couramment mis en oeuvre permettent actuellement de fabriquer de telles pièces avec des tolérances sur les dimensions qui sont de l'ordre de 0,5 à 1%, l'étape de frittage rendant difficile l'obtention de tolérances plus faibles. On peut noter que ces tolérances fluctuent en fonction des lots de matière première utilisés.However, this structure has certain limitations in its application, as well as bracelets of this type known from the prior art generally. Indeed, the cladding parts of hard materials, for example ceramic, are obtained by processes comprising a molding step followed by sintering. During sintering these parts undergo a contraction, that is to say a significant reduction in their volume, under the combined actions of heat and pressure, this contraction may represent more than 30% of the initial volume. The processes currently used currently make it possible to manufacture such parts with tolerances on dimensions which are of the order of 0.5 to 1%, the sintering step making it difficult to obtain lower tolerances. It can be noted that these tolerances fluctuate according to the batches of raw material used.

Les tolérances mises en jeu se traduisent, par exemple, par des incertitudes de l'ordre du cinquième de millimètre sur la longueur d'une boîte de montre en céramique de 3 centimètres. Dans la mesure où ce type de montre se situe dans le haut de gamme de l'horlogerie, une telle incertitude est difficilement acceptable pour leurs fabricants.The tolerances involved result, for example, in uncertainties of the order of one-fifth of a millimeter along the length of a 3 cm ceramic watch case. As this type of watch is in the high end of watchmaking, such uncertainty is hardly acceptable for their manufacturers.

Par conséquent, il était prévu dans l'art antérieur de procéder à un usinage manuel, après l'étape de frittage, pour rattraper les divers jeux existant entre les éléments en céramique de l'habillage d'une telle montre.Therefore, it was planned in the prior art to carry out a manual machining, after the sintering step, to make up the various games existing between the ceramic elements of the dressing of such a watch.

Toutefois, devant la demande croissante des clients pour de tels produits, le nombre de pièces d'horlogerie comportant un habillage en céramique à fabriquer a beaucoup augmenté depuis quelques années, rendant les étapes d'usinage très laborieuses au vu de la quantité de pièces à traiter. En outre, cette étape d'usinage est rendue plus difficile du fait de la complexité croissante des géométries de boîte de montre réalisées actuellement, ce qui complique le blocage de la pièce dans une position donnée pour pouvoir travailler dessus.However, in the face of increasing customer demand for such products, the number of timepieces with a ceramic cladding to manufacture has increased significantly in recent years, making the machining steps very laborious given the amount of parts to treat. In addition, this machining step is made more difficult because of the increasing complexity of the present timepiece geometries, which complicates the blocking of the part in a given position to be able to work on it.

On peut noter que ce problème est d'autant plus gênant que les dimensions des pièces d'habillage à fabriquer sont importantes. En particulier, les tolérances de fabrication mentionnées ci-dessus ont une incidence néfaste au niveau de la boîte de montre, dont les dimensions sont généralement supérieures à celles des maillons de bracelet. De même, plus le fabricant de telles pièces d'horlogerie veut réaliser de maillons de bracelet avec de grandes dimensions, plus il aura de difficultés à réaliser les jonctions entre la boîte de montre et le bracelet ou entre maillons du bracelet présentant une esthétique satisfaisante.It may be noted that this problem is all the more troublesome as the dimensions of the trim parts to be manufactured are important. In particular, the manufacturing tolerances mentioned above have a harmful effect on the watch case, the dimensions of which are generally greater than those of the bracelet links. Similarly, the more the manufacturer of such timepieces wants to make bracelet links with large dimensions, the more difficult it will be to make the junctions between the watch case and the bracelet or between links of the bracelet having a satisfactory aesthetic.

La présente invention a pour but principal de pallier les inconvénients de l'art antérieur susmentionnés et d'améliorer l'esthétique des pièces d'horlogerie existantes.The present invention has the main purpose to overcome the disadvantages of the prior art mentioned above and to improve the aesthetics of existing timepieces.

A cet effet, l'invention a pour objet un maillon pour bracelet de montre du type mentionné plus haut, caractérisé par le fait qu'il comporte un premier élément creux muni de moyens de fixation au bracelet, un second élément dont une partie est imbriquée dans le premier élément et portant des moyens de fixation au boîtier de la montre et un troisième élément externe d'habillage, solidaire du premier élément et recouvrant au moins partiellement le second élément du côté des moyens de fixation au boîtier. Le maillon selon la présente invention est en outre caractérisé par le fait qu'il comporte un dispositif mécanique permettant une translation du premier élément relativement au second élément dans la direction du bracelet, de manière à plaquer le troisième élément d'habillage contre l'élément d'habillage du boîtier de la montre.For this purpose, the subject of the invention is a link for a watch strap of the type mentioned above, characterized in that it comprises a first hollow element provided with fastening means for the bracelet, a second element, part of which is nested. in the first element and carrying means for fixing to the watch case and a third outer casing element, integral with the first element and at least partially covering the second element on the side of the fastening means to the casing. The link according to the present invention is further characterized in that it comprises a mechanical device allowing a translation of the first element relative to the second element in the direction of the bracelet, so as to press the third element of clothing against the element of the case of the watch.

Grâce à ces caractéristiques, un ajustement de la position du bracelet par rapport à la boîte de montre est rendu possible pour corriger les problèmes de tolérances de fabrication. Le résultat d'un tel ajustement est l'obtention d'une jonction ininterrompue entre le bracelet et la boîte de montre, ce qui est avantageux du point de vue esthétique.Thanks to these characteristics, an adjustment of the position of the bracelet with respect to the watch case is made possible to correct manufacturing tolerance problems. The result of such an adjustment is the obtaining of an unbroken junction between the bracelet and the watch case, which is advantageous from the aesthetic point of view.

Dans un premier mode de réalisation, le premier élément est creux et le dispositif mécanique y est logé sous la forme notamment de moyens élastiques, tels qu'un ou plusieurs ressorts ou encore un bloc en élastomère. Ces moyens élastiques exercent une force de rappel sur le premier élément de manière à le rapprocher de la seconde extrémité du second élément, celle-ci portant les moyens de fixation au boîtier de la montre et s'étendant à l'extérieur du premier élément, à travers une ouverture pratiquée dans une paroi de ce dernier. Le résultat obtenu par l'application de cette force de rappel est un rapprochement permanent du troisième élément d'habillage du maillon contre le boîtier de la montre, indépendamment de la valeur des tolérances de fabrication du boîtier de la montre.In a first embodiment, the first element is hollow and the mechanical device is housed in the form of elastic means, such as one or more springs or an elastomer block. These elastic means exert a restoring force on the first element so as to bring it closer to the second end of the second element, the latter carrying the fastening means to the watch case and extending outside the first element, through an opening in a wall of the latter. The result obtained by the application of this restoring force is a permanent approximation of the third element of the link of the link against the watch case, regardless of the value of the manufacturing tolerances of the watch case.

Dans une variante de réalisation, le volume laissé libre par le dispositif mécanique dans le premier élément creux est rendu étanche par rapport à l'environnement extérieur, grâce à l'utilisation d'une structure particulière et de joints adéquats. Cette caractéristique peut être éventuellement mise à profit pour loger divers composants électroniques voire une pile dans le premier élément.In an alternative embodiment, the volume left free by the mechanical device in the first hollow element is sealed against the external environment, through the use of a particular structure and appropriate joints. This feature may be used to accommodate various electronic components or a battery in the first element.

Dans un autre mode de réalisation, les moyens mécaniques comportent des moyens de réglage de la position du bracelet par rapport au boîtier de la montre. Autrement dit, les réglages sont effectués au moment de l'assemblage du bracelet sur le boîtier, de telle sorte que la jonction y est ininterrompue, et peuvent être modifiés ultérieurement. Ces moyens peuvent notamment comporter une vis de réglage, liée de diverses façons aux différents éléments du maillon selon la présente invention.In another embodiment, the mechanical means comprise means for adjusting the position of the bracelet relative to the case of the watch. In other words, the settings are made at the time of assembly of the bracelet on the housing, so that the junction is uninterrupted, and can be changed later. These means may include in particular a set screw, connected in various ways to the various elements of the link according to the present invention.

On peut en effet prévoir que la vis est logée dans un trou ménagé dans le second élément du maillon, que des tampons sont disposés sur la vis de part et d'autre du second élément, ces tampons étant susceptibles d'être déplacés dans une direction perpendiculaire à celle du bracelet, l'un au moins des tampons étant muni d'un filetage. En outre, au moins un guide oblique par rapport à la direction du bracelet est ménagé, pour chaque tampon, sur la paroi du premier élément comportant l'ouverture et/ou sur la première extrémité du second élément, de telle manière que chacun des guides obliques est en butée contre le tampon correspondant, et qu'une rotation de la vis est susceptible de modifier la distance comprise entre les tampons et donc les positions relatives des premier et second éléments.It can indeed be provided that the screw is housed in a hole formed in the second element of the link, that buffers are arranged on the screw on either side of the second element, these buffers being capable of being moved in one direction. perpendicular to that of the bracelet, at least one of the pads being provided with a thread. In addition, at least one oblique guide relative to the direction of the bracelet is provided, for each pad, on the wall of the first element comprising the opening and / or on the first end of the second element, so that each of the guides oblique is abutting against the corresponding buffer, and a rotation of the screw is likely to change the distance between the buffers and therefore the relative positions of the first and second elements.

Cette variante de réalisation permet avantageusement de procéder à un réglage très précis de la position du premier élément par rapport au second élément, et donc de la position du troisième élément d'habillage par rapport au boîtier de la montre.This variant embodiment advantageously makes it possible to carry out a very precise adjustment of the position of the first element relative to the second element, and therefore of the position of the third covering element relative to the watch case.

On peut également prévoir, dans une autre variante de réalisation, que les premier et second éléments du maillon présentent respectivement des surfaces latérales situées en vis-à-vis qui sont au moins partiellement en contact mutuel, la vis traversant une ouverture du second élément laquelle présente une section oblongue allongée, l'extrémité filetée de la vis étant logée dans un trou taraudé ménagé à travers ladite surface du premier élément tandis que la tête de la vis est, en position serrée, en butée contre une face du second élément opposée à ladite surface en contact avec le premier élément.It is also possible, in another variant embodiment, for the first and second elements of the link respectively to have lateral surfaces facing each other which are at least partially in contact with one another, the screw passing through an opening of the second member which has an elongate oblong section, the threaded end of the screw being housed in a threaded hole formed through said surface of the first member while the head of the screw is, in a clamped position, abutting against a face of the second element opposite to said surface in contact with the first element.

Cette variante de réalisation permet d'atteindre un niveau de précision de réglage moindre que celui accessible avec la variante précédente, mais présente l'avantage d'une plus grande simplicité de construction.This variant embodiment makes it possible to achieve a lower level of adjustment accuracy than that accessible with the preceding variant, but has the advantage of greater simplicity of construction.

Il est prévu dans une autre variante de réalisation que la tête de ladite vis est logée à libre rotation dans la paroi dudit premier élément opposée à ladite paroi comportant l'ouverture, tandis que l'extrémité filetée est logée dans un trou taraudé de ladite extrémité du second élément du maillon située à l'intérieur dudit premier élément.It is provided in another alternative embodiment that the head of said screw is housed in free rotation in the wall of said first element opposite said wall having the opening, while the threaded end is housed in a threaded hole of said end. the second element of the link located inside said first element.

De cette façon, même si la tête de la vis n'est pas aussi accessible que dans les variantes précédentes, on peut obtenir un niveau de précision élevé tout en ayant une grande simplicité de construction.In this way, even if the head of the screw is not as accessible as in the previous variants, one can obtain a high level of precision while having great simplicity of construction.

Un autre objet de l'invention est un bracelet de montre tel que définit à la revendication 18 ci-annexée.Another object of the invention is a watch strap as defined in claim 18 appended hereto.

La montre-bracelet ainsi obtenue présente donc une esthétique avantageuse du fait de la continuité existant entre le bracelet et le boîtier.The wristwatch thus obtained therefore has an advantageous aesthetic because of the continuity existing between the bracelet and the case.

On peut prévoir en outre que chacun des maillons du bracelet comporte une structure similaire à celle du maillon assurant la jonction entre le bracelet et le boîtier de la montre, de manière à assurer une continuité des jonctions présentes sur l'ensemble de la montre.It can further be provided that each of the links of the bracelet comprises a structure similar to that of the link connecting the bracelet and the watch case, so as to ensure continuity of the junctions present on the entire watch.

On a représenté sur la figure 1 une montre-bracelet 101 selon l'art antérieur comportant un bracelet 102 relié à un boîtier de montre 103, ces derniers incluant tous deux une structure interne non visible recouverte d'un habillage en céramique 104. On constate sur cette figure que, de part et d'autre du boîtier 103, des jeux, notés d1 et d2, sont apparents au niveau des jonctions entre ledit boîtier et les premiers maillons 105 du bracelet 102.FIG. 1 shows a wristwatch 101 according to the prior art comprising a bracelet 102 connected to a watch case 103, the latter both including a non-visible internal structure covered with a ceramic covering 104. in this figure that, on either side of the housing 103, games, noted d1 and d2 are apparent at the junctions between said housing and the first links 105 of the bracelet 102.

Ces jeux d1 et d2 proviennent, comme cela a été mentionné plus haut, des tolérances de fabrication des éléments d'habillage 104. Dans le cas de la montre 101 représentée ici, les éléments d'habillage du bracelet sont disposés sur la structure interne dans des positions fixes prédéterminées. De ce fait, les variations dimensionnelles des différents éléments d'habillage consécutifs entraînent l'apparition de discontinuités au niveau des jonctions les séparant, ce qui a pour conséquence fâcheuse, du point de vue de l'esthétique, de laisser visibles les moyens de fixation 106 du bracelet sur le boîtier.These sets d1 and d2 come, as mentioned above, manufacturing tolerances of the elements of dressing 104. In the case of the watch 101 shown here, the elements of dressing of the bracelet are arranged on the internal structure in predetermined fixed positions. As a result, the dimensional variations of the various elements of consecutive cladding cause the appearance of discontinuities at the junctions separating them, which has the unfortunate consequence, from the point of view of aesthetics, to leave visible the fixing means 106 of the bracelet on the case.

La présente invention permet de résoudre le problème susmentionné par l'utilisation d'un maillon présentant une structure particulière pour établir la connexion mécanique entre le bracelet et le boîtier.The present invention solves the above problem by using a link having a particular structure to establish the mechanical connection between the bracelet and the housing.

Les figures 2a, 2b et 2c représentent un tel maillon 1 selon un premier mode de réalisation de l'invention. Le maillon 1 comporte un premier élément creux 2, de forme générale parallélépipédique, représenté ici avec un fond 3 dans sa partie inférieure et fermé par un couvercle 4. A titre d'exemple, des vis 5 ont été prévues pour solidariser le couvercle 4 au premier élément 2, les têtes de vis étant disposées en butée contre le couvercle tandis que leurs tiges filetées coopèrent avec des trous taraudés 6 du premier élément.Figures 2a, 2b and 2c show such a link 1 according to a first embodiment of the invention. The link 1 comprises a first hollow element 2, of generally parallelepipedal shape, represented here with a bottom 3 in its lower part and closed by a cover 4. For example, screws 5 have been provided to secure the cover 4 to the first element 2, the screw heads being disposed in abutment against the lid while their threaded rods cooperate with tapped holes 6 of the first element.

Le premier élément 2 comporte une ouverture 7, de préférence sensiblement circulaire, au centre de l'une 8 de ses parois de façon à permettre le passage d'une partie allongée d'un second élément 9 au travers de ladite paroi 8. Le premier élément 2 comporte en outre des moyens de fixation 10 au maillon suivant, de type courant tel que des gonds comme représenté sur les figures, disposés sur la paroi 11 du premier élément 1 opposée à ladite paroi 8 et utilisés en combinaison avec une barrette (non représentée) de type courant.The first element 2 has an opening 7, preferably substantially circular, in the center of one 8 of its walls so as to allow the passage of a an elongate portion of a second element 9 through said wall 8. The first element 2 further comprises fastening means 10 to the next link, of the current type, such as hinges as shown in the figures, arranged on the wall 11 of the first element 1 opposite said wall 8 and used in combination with a bar (not shown) of the current type.

On peut noter que le maillon décrit ci-après peut être utilisé non seulement pour attacher un bracelet au boîtier d'une montre, tel que représenté ici, mais également pour réaliser l'intégralité d'un bracelet de montre. Dans la seconde alternative, il est bien entendu que les moyens de fixation 10 peuvent également servir à établir la connexion mécanique avec des moyens d'attache du bracelet tel qu'une boucle déployante.It may be noted that the link described below may be used not only to attach a bracelet to the case of a watch, as shown here, but also to make the entire watchband. In the second alternative, it is understood that the fastening means 10 can also be used to establish the mechanical connection with strap attachment means such as a folding clasp.

Le second élément 9 présente une forme globale allongée, une première de ses extrémités 12 étant logée à l'intérieur du premier élément creux 2, tandis que la seconde extrémité 13 est située à l'extérieur. La première extrémité 12 s'étend perpendiculairement à la direction longitudinale du bracelet, dans une forme rectangulaire dont les dimensions sont légèrement inférieures aux dimensions intérieures du premier élément. Le second élément comporte en outre une tige 14, de section sensiblement circulaire et légèrement plus petite que l'ouverture 7. Ladite tige 14, partant du centre de la première extrémité 12, traverse ladite ouverture 7, jusqu'à une région présentant une section plus importante définissant ladite seconde extrémité 13. La seconde extrémité 13 comporte un alésage 15 remplissant la fonction de gond, ou moyen de fixation, susceptible de recevoir une barrette pour établir la liaison du second élément 9, et donc du maillon 1, au boîtier de la montre (partiellement schématisé).The second element 9 has an elongated overall shape, a first of its ends 12 being housed inside the first hollow element 2, while the second end 13 is located on the outside. The first end 12 extends perpendicular to the longitudinal direction of the bracelet, in a rectangular shape whose dimensions are slightly smaller than the inner dimensions of the first element. The second element further comprises a rod 14, of substantially circular section and slightly smaller than the opening 7. Said rod 14, starting from the center of the first end 12, passes through said opening 7, to a region having a section more important defining said second end 13. The second end 13 comprises a bore 15 fulfilling the function of hinge, or fixing means, capable of receiving a bar to establish the connection of the second element 9, and therefore of the link 1, to the housing of the watch (partially schematized).

Dans le cas d'un bracelet dont tous les maillons comportent une structure selon la présente invention, ledit alésage peut également permettre d'établir la connexion mécanique avec le maillon précédent, plus précisément avec lesdits moyens de fixation 10 du maillon suivant.In the case of a bracelet of which all the links comprise a structure according to the present invention, said bore may also make it possible to establish the mechanical connection with the preceding link, more precisely with said fastening means 10 of the next link.

On peut noter que, pour des raisons liées à l'assemblage du maillon, ledit second élément comporte deux parties distinctes dont la jonction est effectuée au niveau de la tige 14 au moyen d'une clavette 16 de type classique. Cette caractéristique structurelle indispensable permet en effet de monter ledit second élément 13 au travers de l'ouverture 7.It may be noted that, for reasons related to the assembly of the link, said second element comprises two distinct parts whose junction is made at the rod 14 by means of a key 16 of conventional type. This essential structural characteristic makes it possible to mount said second element 13 through the opening 7.

Un dispositif mécanique particulier, conformément à l'invention, est logé dans le premier élément creux 2. Plus précisément, deux ressorts hélicoïdaux 17 sont interposés, dans le premier élément creux 2, entre la première extrémité 12 du second élément et la paroi 8 du premier élément, de part et d'autre de la tige 14. Lorsque le second élément 9 est disposé de telle manière que sa première extrémité 12 est en appui contre la paroi 11 du premier élément, tel que représenté sur la figure 2b, les ressorts sont dans un état légèrement comprimé.A particular mechanical device, according to the invention, is housed in the first hollow element 2. More precisely, two helical springs 17 are interposed, in the first hollow element 2, between the first end 12 of the second element and the wall 8 of the first element, on both sides of the rod 14. When the second element 9 is arranged such that its first end 12 bears against the wall 11 of the first element, as shown in FIG. 2b, the springs are in a slightly compressed state.

Le maillon comporte en outre un troisième élément principal 18 qui assure une fonction d'habillage. Ce troisième élément d'habillage 18 présente, dans l'exemple représenté, une forme globalement parallélépipédique creuse et est de préférence réalisé en céramique. Les dimensions internes dudit troisième élément 18 sont sensiblement supérieures aux dimensions externes du premier élément 2 et une de ses parois 19 est entièrement ouverte, de manière à pouvoir loger ledit premier élément 2 à l'intérieur du troisième élément 18. D'autre part, la paroi opposée 20 à ladite paroi 19 comporte une ouverture 21 de dimensions sensiblement supérieures à celles de la seconde extrémité 13 du second élément 9 de manière à laisser libre un passage pour celui-ci. Par conséquent, lorsque le maillon 1 est assemblé, le troisième élément d'habillage 18 recouvre au moins partiellement les premier et second éléments.The link further comprises a third main element 18 which provides a dressing function. This third covering member 18 has, in the example shown, a generally hollow parallelepipedal shape and is preferably made of ceramic. The internal dimensions of said third element 18 are substantially greater than the external dimensions of the first element 2 and one of its walls 19 is fully open, so as to accommodate said first element 2 inside the third element 18. On the other hand, the wall opposite said wall 19 has an opening 21 of dimensions substantially greater than those of the second end 13 of the second element 9 so as to leave a passage for it free. Therefore, when the link 1 is assembled, the third covering element 18 at least partially covers the first and second elements.

Dans l'exemple représenté sur les figures, la structure du maillon 1 est telle que le premier élément 2 est intégralement recouvert par ledit troisième élément d'habillage 18.In the example shown in the figures, the structure of the link 1 is such that the first element 2 is completely covered by said third covering element 18.

On constate que dans la mesure où les ressorts 17 s'appuient contre la première extrémité 12 du second élément 9, ils ont tendance à entraîner une translation dudit second élément 9 dans la direction longitudinale du bracelet. Plus exactement, les ressorts 17 exercent une force de rappel sur le second élément 9, symbolisée par les flèches référencées F sur la figure 2a, de façon à en rapprocher la seconde extrémité 13 vers le premier élément 2. La connexion mécanique du maillon 1 avec le boîtier 22 de la montre étant effectuée au niveau de ladite seconde extrémité 13, le résultat obtenu par le fonctionnement de la structure décrite ci-dessus est le rapprochement mutuel dudit boîtier 22 de montre et du maillon 1, jusqu'à ce que l'élément d'habillage du boîtier 22 et le troisième élément d'habillage 18 du maillon se trouvent en butée l'un contre l'autre. On obtient alors, dans une telle configuration, une jonction entre ledit maillon 1 et ledit boîtier 22 qui ne présente pas de discontinuité, ce qui est avantageux du point de vue esthétique.It is found that insofar as the springs 17 bear against the first end 12 of the second element 9, they tend to cause a translation of said second element 9 in the longitudinal direction of the bracelet. More exactly, the springs 17 exert a restoring force on the second element 9, symbolized by the arrows referenced F in FIG. 2a, so as to bring the second end 13 closer to the first element 2. The mechanical connection of the link 1 with the case 22 of the watch being made at said second end 13, the result obtained by the operation of the structure described above is the mutual approximation of said watch case 22 and the link 1, until the housing member 22 and the third cladding element 18 of the link are abutted against each other. In such a configuration, a junction between said link 1 and said housing 22 which does not have a discontinuity is obtained, which is advantageous from an aesthetic point of view.

On peut noter qu'apparaissent des éléments structurels supplémentaires sur les figures 2a, 2b et 2c, qui ont été représentés à titre d'exemple non limitatif.It may be noted that additional structural elements appear in FIGS. 2a, 2b and 2c, which have been shown by way of non-limiting example.

On a en effet prévu de rendre l'intérieur du premier élément du maillon étanche pour, dans un premier temps, protéger le mécanisme de rappel de l'humidité ou de poussières pouvant venir de l'environnement extérieur. On peut par ailleurs prévoir de mettre à profit le volume intérieur disponible du premier élément pour y disposer des composants électroniques ou une pile par exemple. Dans ce but, un joint plat 23, visible sur la figure 2c, est interposé entre la surface supérieure du premier élément 2 et le couvercle 4 le fermant. En outre, une gorge annulaire 24 est ménagée dans la paroi du premier élément 2, dans l'ouverture 7, permettant d'y disposer un joint 25 du type O-ring, visible sur la figure 2c, assurant l'étanchéité entre le premier élément 2 et la tige 14 du second élément 9.It has in fact been planned to make the inside of the first element of the watertight link to initially protect the return mechanism from moisture or dust that may come from the external environment. It is also possible to take advantage of the available interior volume of the first element to have electronic components or a battery for example. For this purpose, a flat gasket 23, visible in FIG. 2c, is interposed between the upper surface of the first element 2 and the lid 4 closing it. In addition, an annular groove 24 is formed in the wall of the first element 2, in the opening 7, to provide a seal O-ring type 25, visible in Figure 2c, sealing between the first element 2 and the rod 14 of the second element 9.

Cette caractéristique supplémentaire ne constituant pas le coeur de l'invention et étant connue de l'art antérieur ne sera pas détaillée davantage dans la présente demande.This additional feature not constituting the core of the invention and being known from the prior art will not be further detailed in the present application.

Dans la description détaillée qui suit, les éléments structurels déjà décrits ci-dessus portent les mêmes numéros de référence que sur les figures 2a à 2c pour faciliter la compréhension de l'invention.In the following detailed description, the structural elements already described above bear the same reference numerals as in FIGS. 2a to 2c to facilitate the understanding of the invention.

Les figures 3a et 3b représentent une variante du mode de réalisation qui vient d'être décrit. En effet, la seule différence distinguant ces deux variantes se situe au niveau de la nature du dispositif mécanique employé pour exercer la force de rappel sur le second élément 9. On constate sur la figure 3a que les ressorts 17 ont été remplacés chacun par un bloc 26 de forme parallélépipédique, de préférence réalisé en caoutchouc ou en tout autre élastomère. Les blocs 26 sont représentés dans un état comprimé sur la figure 3a, donc dans une configuration telle qu'ils exercent une force de rappel sur le second élément 9 de manière à entraîner un rapprochement mutuel du boîtier 22 de montre et du maillon 1. Il peut être prévu qu'en outre lesdits blocs 26 ne sont pas libres dans le premier élément 2, mais qu'ils viennent d'une seule pièce avec le joint plat 23, tel que visible sur la figure 3b. Ainsi, la stabilité de leur position dans le premier élément 2 et donc le bon fonctionnement du dispositif mécanique de rappel sont assurés.Figures 3a and 3b show a variant of the embodiment which has just been described. Indeed, the only difference distinguishing these two variants lies in the nature of the mechanical device used to exert the restoring force on the second element 9. It is noted in Figure 3a that the springs 17 have each been replaced by a block 26 parallelepiped shape, preferably made of rubber or any other elastomer. The blocks 26 are shown in a compressed state in FIG. 3a, and therefore in a configuration such that they exert a restoring force on the second element 9 so as to bring the watchcase 22 and the link 1 closer together. may further be provided said blocks 26 are not free in the first element 2, but they come in one piece with the flat gasket 23, as visible in Figure 3b. Thus, the stability of their position in the first element 2 and thus the proper operation of the mechanical return device are ensured.

Le fonctionnement de l'invention selon ce mode de réalisation est le même que pour le mode de réalisation décrit précédemment, de même que le résultat obtenu.The operation of the invention according to this embodiment is the same as for the embodiment described above, as well as the result obtained.

Les modes de réalisation suivants sont basés sur un fonctionnement différent de ce qui précède, dans la mesure où le dispositif mécanique logé dans le premier élément 2 n'a plus pour fonction d'assurer une force de rappel sur le second élément 9 du maillon 1 mais un simple réglage.The following embodiments are based on a different operation of the above, insofar as the mechanical device housed in the first element 2 no longer has the function of ensuring a restoring force on the second element 9 of the link 1 but a simple adjustment.

Dans la variante représentée sur les figures 4a et 4b, les premier et second éléments présentent des formes différentes de celles précédemment décrites. Le second élément 9 du maillon 1 est ici réalisé d'une seule pièce comportant deux parties principales perpendiculaires l'une à l'autre, dont l'une définit la première extrémité 12 tandis que l'autre 27 porte la seconde extrémité 13. Ladite première extrémité 12 présente une forme générale de parallélépipède dont les deux arêtes orthogonales à la direction longitudinale du bracelet et situées du côté de la seconde partie principale 27 sont tronquées, de façon à définir deux plans inclinés 28. La seconde partie principale 27 s'étend, à partir du milieu de la première extrémité 12, dans une forme générale de parallélépipède allongé dans la direction longitudinale du bracelet. Elle comporte, à proximité de ladite première extrémité 12, une ouverture 29 la traversant dans le sens de la largeur et présentant une section oblongue. Elle comporte en outre, à l'opposé de ladite première extrémité 12, un alésage 15 remplissant la fonction de gond, ou moyen de fixation, et définissant la seconde extrémité 13 du second élément. Ledit gond 15 est susceptible de recevoir une barrette (non représentée) pour établir la liaison du second élément 9, et donc du maillon 1, au boîtier 22 de la montre (partiellement schématisé).In the variant shown in Figures 4a and 4b, the first and second elements have different shapes from those previously described. The second element 9 of the link 1 is here made in one piece comprising two main parts perpendicular to each other, one of which defines the first end 12 while the other 27 carries the second end 13. Said first end 12 has a general parallelepiped shape whose two edges orthogonal to the longitudinal direction of the bracelet and located on the side of the second main portion 27 are truncated, so as to define two inclined planes 28. The second main portion 27 extends, from the middle of the first end 12, in a general shape of parallelepiped elongated in the longitudinal direction of the bracelet. It comprises, near said first end 12, an opening 29 passing therethrough in the width direction and having an oblong section. It further comprises, opposite said first end 12, a bore 15 fulfilling the function of hinge, or fixing means, and defining the second end 13 of the second element. Said hinge 15 is capable of receiving a bar (not shown) to establish the connection of the second element 9, and therefore of the link 1, to the housing 22 of the watch (partially schematized).

Le premier élément présente, dans sa paroi 8, une ouverture 7 de section rectangulaire dont les dimensions sont sensiblement supérieures à celles de la seconde partie principale 27 du second élément 9. Ladite paroi 8 comporte en outre des évidements 30 au niveau de chacune de ses jonctions avec les flancs latéraux 31 du premier élément 2. Ces évidements 30 définissent ainsi des plans inclinés 32 dont les angles respectifs à la direction longitudinale du bracelet sont opposés à ceux des angles que présentent les plans inclinés 28, respectivement situés en vis-à-vis, de la première extrémité 12.The first element has, in its wall 8, an opening 7 of rectangular section whose dimensions are substantially greater than those of the second main portion 27 of the second element 9. Said wall 8 further comprises recesses 30 at each of its junctions with the lateral flanks 31 of the first element 2. These recesses 30 and define inclined planes 32 whose respective angles to the longitudinal direction of the bracelet are opposed to those of the angles that have the inclined planes 28, respectively located vis-à- screw, from the first end 12.

Un desdits flancs latéraux 31 du premier élément comporte une ouverture cylindrique 33 dont la fonction sera décrite plus loin.One of said lateral flanks 31 of the first element comprises a cylindrical opening 33 whose function will be described later.

Une vis 34 est disposée à travers l'ouverture 29 du second élément 9, la tête 35 de ladite vis étant disposée en regard de l'ouverture cylindrique 33 pour être rendue accessible par un opérateur.A screw 34 is disposed through the opening 29 of the second element 9, the head 35 of said screw being disposed opposite the cylindrical opening 33 to be made accessible by an operator.

Deux tampons 36, 37 sont disposés sur ladite vis 34, de part et d'autre du second élément 9. De préférence, ces tampons 36, 37 sont réalisés en un élastomère dont le choix ne posera aucun problème à l'homme de l'art. Tel que visible sur la figure 4c représentant une vue en perspective du tampon 36, chacun desdits tampons comporte deux bases rectangulaires parallèles 38, 39 et quatre faces, dont deux faces opposées 40 sont perpendiculaires auxdites bases, les deux autres faces 41 étant inclinées par rapport à l'axe de la vis d'un angle de même valeur que lesdits plans inclinés 28 et 32 situés en regard. Les deux faces 41 présentent une forme rectangulaire tandis que les deux autres faces 40 sont en formes de trapèzes. Les tampons comportent en outre chacun un trou traversant 42, perpendiculaire auxdites bases en leur centre.Two buffers 36, 37 are disposed on said screw 34, on either side of the second element 9. Preferably, these buffers 36, 37 are made of an elastomer whose choice will pose no problem to the man of the art. As can be seen in FIG. 4c showing a perspective view of the buffer 36, each of said buffers comprises two parallel rectangular bases 38, 39 and four faces, of which two opposite faces 40 are perpendicular to said bases, the other two faces 41 being inclined relative to each other. to the axis of the screw of an angle of the same value as said inclined planes 28 and 32 located opposite. The two faces 41 have a rectangular shape while the other two faces 40 are trapezoidal shapes. The buffers each further comprise a through hole 42, perpendicular to said bases in their center.

Un premier tampon 36, situé du côté de la tête 35 de la vis, comporte également un dégagement cylindrique 43 de dimensions telles que ladite tête 35 de la vis peut y être logée intégralement. Ledit dégagement cylindrique 43 et ledit trou traversant 42 présentent respectivement des dimensions sensiblement supérieures à celles respectivement de la tête 35 et de la tige de vis 34, de sorte qu'une rotation libre de la vis 34 dans le tampon 36 est possible.A first buffer 36, located on the side of the head 35 of the screw, also comprises a cylindrical clearance 43 of dimensions such that said head 35 of the screw can be housed fully. Said cylindrical clearance 43 and said through hole 42 respectively have dimensions substantially greater than those respectively of the head 35 and the screw rod 34, so that a free rotation of the screw 34 in the buffer 36 is possible.

Le deuxième tampon 37 comporte, dans son trou traversant, un taraudage coopérant avec le filetage de la vis 34 et est situé à proximité de l'extrémité de la tige de vis 34.The second buffer 37 comprises, in its through hole, a tapping cooperating with the thread of the screw 34 and is located near the end of the screw rod 34.

On constate que pour passer de la configuration représentée sur la figure 4a à la configuration représentée sur la figure 4b, la vis 34 a été "serrée", autrement dit, on a tourné ladite vis dans le sens horaire. En effet, lorsque ladite vis 34 est tournée dans le sens horaire, le tampon 37 effectue une translation pour se rapprocher de la tête 35 de ladite vis 34. Dans la mesure où la position du tampon 36 par rapport à ladite vis 34 est fixe, la translation du tampon 37 vers la tête de vis 35 provoque un rapprochement mutuel desdits deux tampons 36 et 37. Ce rapprochement est rendu possible par un glissement des faces inclinées de chacun des tampons sur les plans inclinés 28 et 32 correspondants formant guides obliques pour lesdits tampons. Ledit glissement entraîne en outre un écartement mutuel de la première extrémité 12 du second élément 9 et de la paroi 8 du premier élément 2. Ledit écartement correspond à un rapprochement mutuel de la seconde extrémité 13 du second élément 9 et du premier élément 2, ce qui correspond également à un rapprochement mutuel du maillon 1 et du boîtier 22, tel que cela apparaît sur la figure 4b.It is found that to go from the configuration shown in Figure 4a to the configuration shown in Figure 4b, the screw 34 has been "tightened", that is, it turned said screw clockwise. Indeed, when said screw 34 is turned clockwise, the buffer 37 translates to move closer to the head 35 of said screw 34. Insofar as the position of the buffer 36 relative to said screw 34 is fixed, the translation of the buffer 37 towards the screw head 35 brings the two buffers 36 and 37 closer together. This approximation is made possible by a sliding of the inclined faces of each of the buffers on the inclined planes 28 and 32 corresponding to oblique guides for said buffers. Said sliding also causes the first end 12 of the second element 9 and the wall 8 of the first element 2 to move apart from one another. Said spacing corresponds to a mutual approach between the second end 13 of the second element 9 and the first element 2, which which also corresponds to a mutual approximation of the link 1 and the housing 22, as shown in Figure 4b.

Grâce au fonctionnement du dispositif mécanique décrit ci-dessus, on obtient une jonction continue entre le maillon 1 et le boîtier 22 de la montre, ce qui constitue l'avantage esthétique recherché.Thanks to the operation of the mechanical device described above, there is obtained a continuous junction between the link 1 and the housing 22 of the watch, which is the desired aesthetic advantage.

Le mode de réalisation représenté sur les figures 5a à 5c fait également appel à l'utilisation d'une vis 34 logée dans le premier élément 2 du maillon 1. De même que dans le mode de réalisation précédent, ladite vis est disposée à travers une ouverture 29 du second élément, de section oblongue de plus grande largeur que dans le mode de réalisation précédent, et sa tête 35 est accessible à travers une ouverture 33 ménagée dans l'un des flancs latéraux 31 dudit premier élément. Toutefois, dans la présente variante, l'extrémité 44 de la tige filetée de la vis 34 est logée dans un trou taraudé 45, pratiqué dans le flanc latéral 31 du premier élément opposé à celui comportant l'ouverture 33.The embodiment shown in FIGS. 5a to 5c also makes use of the use of a screw 34 housed in the first element 2 of the link 1. As in the previous embodiment, said screw is disposed through a opening 29 of the second element, oblong section of greater width than in the previous embodiment, and its head 35 is accessible through an opening 33 formed in one of the lateral flanks 31 of said first element. However, in the present variant, the end 44 of the threaded rod of the screw 34 is housed in a threaded hole 45 formed in the lateral flank 31 of the first element opposite to that having the opening 33.

Pour compléter le dispositif mécanique de réglage qui vient d'être décrit, on note qu'une grande partie 46 du flanc latéral 31 comportant ledit trou taraudé 45, proche de la paroi 8 du premier élément, présente une épaisseur plus importante que la partie dudit flanc 31 la plus éloignée de ladite paroi 8. Ainsi, ladite partie 46 se trouve en contact avec le côté de la partie principale 27 du second élément située du même côté lorsque la vis 34 est en position serrée, tel que représenté sur la figure 5b.To complete the mechanical adjustment device that has just been described, it is noted that a large portion 46 of the lateral flank 31 comprising said tapped hole 45, close to the wall 8 of the first element, has a greater thickness than the portion of said flank 31 farthest from said wall 8. Thus, said part 46 is is in contact with the side of the main portion 27 of the second element located on the same side when the screw 34 is in the tightened position, as shown in Figure 5b.

Pour effectuer le réglage des positions relatives du maillon 1 et du boîtier de montre 22, la vis 34 est desserrée dans une position similaire à celle représentée sur la figure 5a. Dans une telle configuration, les forces de frottement intervenant entre la partie 46 du premier élément 2 et la seconde partie principale 27 du second élément 9 sont faibles. Ainsi, une translation du premier élément 2 par rapport au second élément 9, ou inversement, est rendue possible. On dispose alors le second élément 9 par rapport au premier 2 de telle manière que, lorsque le maillon 1 est monté au boîtier de montre 22, le troisième élément d'habillage 18 est à fleur dudit boîtier 22. La vis 34 est alors serrée jusqu'à ce que sa tête 35 arrive en butée contre la partie 27 du second élément 9, ce qui a pour effet de serrer le second élément 9 contre la partie 46 du premier élément 2. Dans cette configuration représentée sur la figure 5b, les forces de frottement entre les premier et second éléments 2, 9 sont si importantes qu'une translation de l'un de ces éléments par rapport à l'autre n'est plus possible.To adjust the relative positions of the link 1 and the watch case 22, the screw 34 is loosened to a position similar to that shown in FIG. 5a. In such a configuration, the friction forces occurring between the portion 46 of the first element 2 and the second main portion 27 of the second element 9 are small. Thus, a translation of the first element 2 relative to the second element 9, or vice versa, is made possible. The second element 9 is then disposed relative to the first 2 in such a way that, when the link 1 is mounted to the watch case 22, the third covering element 18 is flush with the said case 22. The screw 34 is then tightened its head 35 abuts against the part 27 of the second element 9, which has the effect of clamping the second element 9 against the portion 46 of the first element 2. In this configuration shown in FIG. 5b, the forces friction between the first and second elements 2, 9 are so important that a translation of one of these elements relative to the other is no longer possible.

La montre-bracelet peut alors être assemblée sans que sa structure interne ne soit visible au niveau des jonctions entre le boîtier 22 et les premiers maillons 1, situés de part et d'autre dudit boîtier.The wristwatch can then be assembled without its internal structure being visible at the junctions between the housing 22 and the first links 1, located on either side of said housing.

Le maillon 1 selon un autre mode de réalisation, représenté sur les figures 6a et 6b, comporte également une vis 34 mais disposée ici dans la direction longitudinale du bracelet. Le premier élément 2 présente une forme simplifiée par rapport aux variantes précédentes. En effet, la forme générale de l'élément 2 est parallélépipédique et comporte un évidement 47, également de forme parallélépipédique, partant de la paroi 8, s'étendant sur toute la hauteur de l'élément 2 et sur la majeure partie de sa largeur. Le premier élément 2 comporte en outre une ouverture cylindrique 48 traversant le premier élément 2 à partir de sa paroi 11 jusqu'à l'évidement 47. Ladite ouverture 48 comporte, à partir de la paroi 11 et dans la direction longitudinale du bracelet, deux portions 49, 50 dont la première 49 présente un diamètre plus important que celui de la seconde portion 50 débouchant dans l'évidement 47.The link 1 according to another embodiment, shown in Figures 6a and 6b, also comprises a screw 34 but arranged here in the longitudinal direction of the bracelet. The first element 2 has a simplified form compared to the previous variants. Indeed, the general shape of the element 2 is parallelepiped and comprises a recess 47, also of parallelepipedal shape, starting from the wall 8, extending over the entire height of the element 2 and over most of its width . The first element 2 further comprises a cylindrical opening 48 through the first element 2 from its wall 11 to the recess 47. Said opening 48 comprises, from the wall 11 and in the longitudinal direction of the bracelet, two portions 49, 50 whose first 49 has a greater diameter than that of the second portion 50 opening into the recess 47.

Le second élément 9 comporte, à partir de sa première extrémité 12, une première portion 51 de section constante sensiblement inférieure aux dimensions de l'évidement 47, suivie d'une seconde portion 52 de section légèrement supérieure à celle de ladite première portion et se terminant par la seconde extrémité 13, de même section que la première portion. Le second élément 9 comporte en outre un trou taraudé 53 ménagé à partir de la première extrémité 12, dans la direction longitudinale du bracelet.The second element 9 comprises, from its first end 12, a first portion 51 of constant section substantially smaller than the dimensions of the recess 47, followed by a second portion 52 of section slightly greater than that of said first portion and terminating at the second end 13, of the same section as the first portion. The second element 9 further comprises a tapped hole 53 formed from the first end 12, in the longitudinal direction of the bracelet.

Le troisième élément d'habillage 18 comporte dans sa paroi 20 une ouverture 21 de section rectangulaire et dont les dimensions sont sensiblement supérieures à celles de la seconde portion 52 du second élément 9. En outre, la longueur de ladite seconde portion 52 est sensiblement égale à l'épaisseur de ladite paroi 20.The third covering element 18 comprises in its wall 20 an opening 21 of rectangular section and whose dimensions are substantially greater than those of the second portion 52 of the second element 9. In addition, the length of said second portion 52 is substantially equal to the thickness of said wall 20.

La vis 34 est disposée dans le maillon 1, de telle manière que sa tête 35 et une courte partie de sa tige sont logées dans l'ouverture cylindrique 48 du premier élément 2, la tête 35 étant en appui contre la jonction séparant les portions 49 et 50. Dans la présente variante, la tête 35 de ladite vis est accessible par la paroi 19 ouverte du troisième élément d'habillage 18. L'extrémité 44 de la vis 34 est vissée dans le trou taraudé 53 du second élément 9. Ainsi, la vis 34 est libre de tourner sur elle-même sans se déplacer par rapport au premier élément 2 alors que son degré de pénétration dans le second élément 9 peut être modifié par vissage ou dévissage.The screw 34 is disposed in the link 1, so that its head 35 and a short portion of its rod are housed in the cylindrical opening 48 of the first element 2, the head 35 being in abutment against the junction separating the portions 49. and 50. In the present variant, the head 35 of said screw is accessible through the open wall 19 of the third covering element 18. The end 44 of the screw 34 is screwed into the threaded hole 53 of the second element 9. , the screw 34 is free to rotate on itself without moving relative to the first element 2 while its degree of penetration into the second element 9 can be modified by screwing or unscrewing.

Par conséquent, lorsque la vis 34 est vissée, respectivement dévissée, dans le second élément 9, sa première extrémité 12 se rapproche, respectivement s'éloigne, de la paroi 11 du premier élément 2. Dans la mesure où la seconde extrémité 13 du second élément est reliée au boîtier 22 de la montre, ce dernier subit les mêmes mouvements que ceux décrits ci-dessus pour la première extrémité 12.Consequently, when the screw 34 is screwed, respectively unscrewed, into the second element 9, its first end 12 moves towards and away from the wall 11 of the first element 2, insofar as the second end 13 of the second element element is connected to the housing 22 of the watch, the latter undergoes the same movements as those described above for the first end 12.

On obtient donc, par cette structure relativement simple, une possibilité de réglage fin de la position du boîtier 22 par rapport au maillon 1, corrigeant toute discontinuité entre ces deux éléments susceptible de survenir du fait du procédé de fabrication utilisé pour la réalisation de leurs habillages respectifs.This relatively simple structure therefore provides a possibility of fine adjustment of the position of the housing 22 with respect to the link 1, correcting any discontinuity between these two elements that may occur due to the manufacturing process used to produce their skins. respectively.

On peut évidemment envisager de réaliser par exemple le premier élément 2 avec une forme plus complexe, notamment en prévoyant une zone creuse et des moyens pour rendre ladite zone creuse étanche par rapport à l'environnement extérieur, afin de pouvoir y loger des composants électroniques.It is obviously conceivable to produce for example the first element 2 with a more complex shape, in particular by providing a hollow zone and means for rendering said hollow zone watertight relative to the external environment, in order to accommodate electronic components therein.

La description qui précède correspond à des modes de réalisation préférés de l'invention et ne saurait en aucun cas être considérée comme limitative, en ce qui concerne plus particulièrement la forme décrite pour les différents éléments structurels composant le maillon selon l'invention. De même, l'homme de l'art est capable d'adapter sans difficulté les dimensions des divers éléments structurels en fonction de la nature de la céramique employée, par exemple, pour construire le dispositif mécanique avec suffisamment de débattement pour pouvoir obtenir des jonctions continues entre les différents éléments d'habillage de la montre.The foregoing description corresponds to preferred embodiments of the invention and can in no way be considered as limiting, with particular reference to the form described for the different structural elements constituting the link according to the invention. Similarly, one skilled in the art is able to easily adapt the dimensions of the various structural elements depending on the nature of the ceramic used, for example, to build the mechanical device with enough movement to be able to get junctions continuous between the different elements of dressing of the watch.
