Description

La présente invention se rapporte à un bracelet articulé à maillons disposés pour s'interpénétrer dans le sens longitudinal et reliés par des axes transversaux d'articulation (voir EP-A- 1048 240 ).The present invention relates to an articulated bracelet with links arranged to interpenetrate in the longitudinal direction and connected by transverse axes of articulation (see EP-A-1048 240 ).

On connaît des bracelets de ce genre, notamment des bracelets de montres dans lesquels au moins certaines séries transversales de maillons adjacents sont démontables pour permettre de modifier la longueur du bracelet en fonction de la grosseur du poignet du porteur de ce bracelet. En général, ces séries transversales de maillons démontables sont assemblées par des vis qui sont visibles sur la tranche du bracelet. Les autres séries transversales de maillons sont reliées par des goupilles chassées dans les maillons latéraux, pour permettre à ceux-ci de pivoter par rapport aux maillons centraux.There are known bracelets of this kind, including watchbands in which at least some transverse series of adjacent links are removable to allow to change the length of the bracelet depending on the size of the wrist wearer of this bracelet. In general, these transverse series of removable links are assembled by screws which are visible on the edge of the bracelet. The other transverse series of links are connected by pins driven into the side links, to allow them to pivot relative to the central links.

Outre le fait que les vis sont visibles, un tel bracelet n'est pas entièrement démontable et nécessite une intervention délicate pour séparer les maillons tenus par des goupilles au cas où il serait nécessaire de changer un maillon.Besides the fact that the screws are visible, such a bracelet is not completely removable and requires a delicate intervention to separate the links held by pins in case it would be necessary to change a link.

On a déjà proposé dans le EP-0089 421 , le WO 93/08713 et le WO 94/12069 des bracelets articulés démontables, assemblés par des éléments d'articulation engagés librement sur des chevilles de pivotement, ces éléments d'articulation étant verrouillés par des organes vissés sur le côté du bracelet tourné vers le bras du porteur, de sorte que les vis ne sont pas visibles lorsque le bracelet est porté. Il s'agit là sans doute d'une amélioration sur le plan de l'esthétique, qui ne saurait cependant répondre aux critères les plus exigeants qui sont ceux d'articles haut de gamme. En effet, dans une vitrine ou lors de l'achat, le client voit d'abord le bracelet non porté, de sorte qu'il peut remarquer les vis de fixation quelle que soit la face du bracelet sur laquelle elles apparaissent. Le fait de voir des vis confère immédiatement à un tel bracelet le caractère d'un objet dont le côté fonctionnel à pris le pas sur le côté esthétique, ce qui n'est évidemment pas valorisant pour un article haut de gamme de ce type, dont l'aspect irréprochable est le gage de sa bonne facture.We have already proposed in the EP-0089 421 , the WO 93/08713 and the WO 94/12069 removable articulated bracelets, assembled by hinge elements freely engaged on pivot pins, these hinge elements being locked by members screwed on the side of the bracelet facing the wearer's arm, so that the screws are not not visible when the bracelet is worn. This is undoubtedly an improvement in terms of aesthetics, which however can not meet the most demanding criteria that are those of high-end items. Indeed, in a shop window or during the purchase, the customer sees first the bracelet not worn, so he can notice the fixing screws whatever the face of the bracelet on which they appear. The fact of seeing screws immediately gives such a bracelet the character of an object whose functional side takes precedence over the aesthetic side, which is obviously not rewarding for a high-end article of this type, which the irreproachable aspect is the pledge of its good invoice.

Le brevet CH-558 153 est relatif à un bracelet articulé comprenant des maillons solidaires d'une tige d'articulation transversale qui fait saillie à une extrémité du maillon et qui ne s'étend pas sur toute sa largeur. Cette tige est introduite dans un logement s'ouvrant sur la face inférieure du maillon adjacent et maintenue en place par un élément de verrouillage à ressort. Dans ce cas, les vis sont remplacées par un ressort. Dans le cas d'un bracelet en or, un tel ressort pourrait difficilement être dans le même métal que le bracelet. Par ailleurs, même si il ne s'agit pas d'une vis, cet organe de fixation doit présenter une ouverture pour permettre le démontage et conserve donc un caractère fonctionnel et non décoratif, lui donnant un aspect dont l'esthétique ne s'intègre pas au reste du bracelet.The patent CH-558 153 is relative to an articulated bracelet comprising links integral with a transverse articulation rod which projects at one end of the link and which does not extend over its entire width. This rod is inserted into a housing opening on the underside of the adjacent link and held in place by a spring locking member. In this case, the screws are replaced by a spring. In the case of a gold bracelet, such a spring could hardly be in the same metal as the bracelet. Moreover, even if it is not a screw, this fastener must have an opening to allow disassembly and therefore retains a functional and non-decorative, giving it an aspect whose aesthetic does not integrate not the rest of the bracelet.

Une autre solution a été proposée dans le CH-688 430 , qui consiste à former des maillons comprenant trois parties de largeurs différentes, décalées longitudinalement les une par rapport aux autres. Une partie centrale étroite est suivie par une partie de largeur intermédiaire s'étendant de part et d'autre de l'axe médian du bracelet et enfin par une partie dont la largeur correspond à celle du bracelet. Chaque partie centrale et chaque partie de largeur intermédiaire est percée transversalement au bracelet. Chaque partie large du maillon comporte un dégagement de largeur correspondant à la largeur intermédiaire, et chaque partie intermédiaire comporte un dégagement de largeur correspondant à la partie centrale la plus étroite. De ce fait, deux maillons adjacents peuvent s'imbriquer l'un dans l'autre et être retenus ensemble par une barrette glissée dans les ouvertures transversales coaxiales des parties intermédiaires et de la partie centrale du maillon adjacent. Cette barrette passe librement à travers ces ouvertures, mais est retenue axialement dès que l'on place le maillon suivant. En effet, la barrette vient buter contre les bords du dégagement de largeur correspondante de ce maillon suivant et est donc bloquée axialement. Le principal inconvénient de cette solution réside dans le fait que l'amplitude de l'articulation de maillons doit être limitée pour que la barrette soit toujours en butée contre les bords du dégagement du maillon suivant. Par ailleurs, avec cette solution, les maillons sont nécessairement décalés longitudinalement les uns par rapport aux autres.Another solution has been proposed in the CH-688 430 which consists in forming links comprising three parts of different widths, offset longitudinally relative to each other. A narrow central portion is followed by a portion of intermediate width extending on either side of the median axis of the bracelet and finally by a portion whose width corresponds to that of the bracelet. Each central portion and each intermediate width portion is pierced transversely to the bracelet. Each wide part of the link has a width clearance corresponding to the intermediate width, and each intermediate portion has a clearance width corresponding to the narrowest central part. As a result, two adjacent links can interlock with one another and be held together by a bar slid into the coaxial transverse openings of the intermediate portions and the central portion of the adjacent link. This bar passes freely through these openings, but is retained axially as soon as we place the next link. Indeed, the bar abuts against the edges of the clearance of corresponding width of the next link and is therefore locked axially. The main drawback of this solution lies in the fact that the amplitude of the link articulation must be limited so that the bar is always in abutment against the edges of the release of the next link. Moreover, with this solution, the links are necessarily offset longitudinally with respect to each other.

On a enfin proposé dans le EP 0 310 536 un bracelet comportant deux rangées de maillons latéraux, chacun solidaire d'un demi-axe qui se termine par une tête adjacente à une gorge. Deux maillons intermédiaires sont disposés entre ces maillons latéraux et un maillon central. Les maillons intermédiaires présentent deux passages parallèles à axes transversaux, dont l'un est destiné à recevoir un demi-axe en laissant dépasser la tête et la gorge adjacente. Le maillon central de fixation présente un évidement longitudinal dont la section est de forme complémentaire de celle des deux têtes des deux demi-axes. L'évidement longitudinal s'ouvre à une extrémité et présente deux fentes latérales dont la largeur correspond au diamètre des gorges adjacentes aux têtes des demi-axes.We finally proposed in the EP 0 310 536 a bracelet comprising two rows of lateral links, each integral with a half-axis which ends with a head adjacent to a groove. Two intermediate links are arranged between these side links and a central link. The intermediate links have two parallel passages with transverse axes, one of which is intended to receive a half axis leaving the head and the adjacent groove. The central fastening link has a longitudinal recess whose section is of complementary shape to that of the two heads of the two half-axes. The longitudinal recess opens at one end and has two lateral slots whose width corresponds to the diameter of the grooves adjacent to the heads of the half-shafts.

Pour monter le bracelet, on engage les deux demi-axes dans les passages respectifs de deux maillons intermédiaires, puis on introduit les deux têtes des demi-axes dans l'évidement longitudinal à partir de son extrémité ouverte. On fait coulisser longitudinalement chaque paire de maillons latéraux intermédiaires jusqu'à ce que les autres passages des maillons intermédiaires coïncident avec le passage du maillon central. On introduit alors une tige de pivotement à travers les deux passages, de sorte que tous les maillons composant le bracelet sont articulés autour de deux axes.To mount the bracelet, the two half-shafts are engaged in the respective passages of two intermediate links, then the two heads of the half-shafts are introduced into the longitudinal recess from its open end. Each pair of intermediate side links is slid longitudinally until the other passages of the intermediate links coincide with the passage of the central link. A pivot rod is then introduced through the two passages, so that all the links constituting the bracelet are articulated around two axes.

Bien qu'un tel bracelet ne comporte pas de vis et qu'aucun élément faisant partie de l'assemblage ne soit visible en position d'utilisation, c'est-à-dire lorsque le bracelet entoure le poignet, l'extrémité de l'évidemment longitudinal qui débouche dans une face latérale du bracelet devient visible dès qu'un angle suffisant est formé entre cette face latérale et le maillon adjacent à cette face latérale.Although such a bracelet has no screws and no part of the assembly is visible in the use position, that is to say when the bracelet surrounds the wrist, the end of the obviously longitudinal which opens into a side face of the bracelet becomes visible as soon as a sufficient angle is formed between this side face and the link adjacent to this side face.

Le but de la présente invention est un bracelet articulé à maillons dans lequel aucun élément d'assemblage ne soit visible, sur aucune face, même une face latérale de maillons qui se situe à l'intérieur du bracelet. Le but de cette invention est aussi d'avoir le moins possible, voire aucun élément d'assemblage à vis, pour éviter tout risque de dévissage d'une vis pas suffisamment serrée.The object of the present invention is an articulated bracelet with links in which no assembly element is visible on any face, even a lateral face of links which is located inside the bracelet. The object of this invention is also to have as little as possible, or even no screw connection element, to avoid any risk of unscrewing a screw not sufficiently tight.

A cet effet, cette invention a pour objet un bracelet articulé à maillons selon la revendication 1.For this purpose, this invention relates to an articulated link bracelet according to claim 1.

Malgré l'absence de vis entre les ensembles modulaires dont est formé le bracelet, celui-ci est entièrement démontable sans aucun outil, ce qui permet de le mettre facilement à la bonne longueur lors de la vente d'une montre dans le cas d'un bracelet de montre.Despite the lack of screws between the modular sets of which is formed the bracelet, it is completely removable without any tools, which allows to easily put it to the right length when selling a watch in the case of a watch bracelet.

Le verrouillage des tiges transversales d'articulation de ce bracelet est obtenu par le basculement des deux parties d'un ensemble modulaire autour de l'axe transversal médian, destiné à faire coïncider les deux maillons alignés transversalement avec la tige transversale d'articulation. Ainsi, la mise en place de chaque élément modulaire permet, en immobilisant en rotation les deux parties de l'ensemble modulaire autour de l'axe transversal médian, de verrouiller axialement la tige transversale d'articulation entre les faces latérales tournées vers l'intérieur des deux maillons respectifs des rangées latérales voire entre une face latérale d'un maillon d'une rangée latérale et le maillon de la rangée latérale opposée lorsque la tige est solidaire de ce dernier maillon.The locking of the transverse rods of articulation of this bracelet is obtained by tilting the two parts of a modular assembly around the transverse axis median, intended to align the two links aligned transversely with the transverse rod articulation. Thus, the introduction of each modular element makes it possible, by immobilizing in rotation the two parts of the modular assembly around the median transverse axis, to axially lock the transverse articulation rod between the lateral faces facing inwards. two respective links of the lateral rows or between a side face of a link of a lateral row and the link of the opposite lateral row when the rod is secured to the latter link.

De préférence, les tiges transversales d'articulation sont libres, en sorte que leur usure résultant de l'oscillation des deux éléments modulaires autour de lui est réduite au minimum.Preferably, the transverse hinge rods are free, so that their wear resulting from the oscillation of the two modular elements around it is reduced to a minimum.

Le bracelet selon l'invention est formé d'une succession d'ensembles modulaires 1 similaires, articulés les uns aux autres, dont l'un est illustré avant assemblage par la figure 1. Cet ensemble modulaire comporte cinq maillons adjacents 2, 3, 4, 5, 6 dans le sens transversal du bracelet, chacun d'eux faisant partie d'une des cinq rangées longitudinales de maillons formant le bracelet. Ces maillons 2-6 occupent alternativement deux positions longitudinales et sont reliés les uns aux autres par un premier axe transversal médian 7 qui passe librement au travers d'ouvertures transversales de guidage 3a, 4a, 5a des maillons 3-5 et dont les deux extrémités sont chassées dans des trous borgnes 2a, 6a ménagés dans les faces latérales internes des deux maillons latéraux 2 et 6. Par conséquent, en position assemblée de l'ensemble modulaire 1, les deux maillons latéraux 2, 6 et le maillon central 4 sont alignés dans une des deux positions longitudinales, tandis que les deux maillons 3, 5 sont alignés transversalement dans la seconde position longitudinale et forment deux saillies qui sont destinées à pénétrer dans deux parties rentrantes d'un ensemble modulaire adjacent, formées entre les trois maillons 2, 4 et 6.The bracelet according to the invention is formed of a succession of modular assemblies 1 similar, articulated to each other, one of which is illustrated before assembly by the figure 1 . This modular assembly comprises five adjacent links 2, 3, 4, 5, 6 in the transverse direction of the bracelet, each of them forming part of one of the five longitudinal rows of links forming the bracelet. These links 2-6 occupy alternately two longitudinal positions and are connected to each other by a first median transverse axis 7 which passes freely through transverse guide openings 3a, 4a, 5a of links 3-5 and whose two ends are driven into blind holes 2a, 6a formed in the internal lateral faces of the two lateral links 2 and 6. Therefore, in the assembled position of the modular assembly 1, the two lateral links 2, 6 and the central link 4 are aligned in one of the two longitudinal positions, while the two links 3, 5 are aligned transversely in the second longitudinal position and form two projections which are intended to penetrate into two re-entrant parts of an adjacent modular assembly, formed between the three links 2, 4 and 6.

Ces deux maillons 3, 5 et le maillon central 4 comportent chacun une seconde ouverture transversale de guidage 3b, respectivement 4b, 5b qui traverse leurs parties décalées respectives par rapport à l'axe transversal médian 7 et situées toutes trois à la même distance de cet axe. Un des maillons 3, 5 est solidaire du maillon latéral adjacent 2 ou 6, tandis que l'autre de ces maillons 3, 5 est solidaire du maillon central 4. Comme les deux maillons latéraux 2, 6 sont chassés sur l'axe de liaison 7 et que l'un d'eux est solidaire du maillon adjacent 3 ou 5, trois maillons sont solidaires de l'axe transversal médian 7 et forment une première partie de l'ensemble modulaire 1. Les deux autres maillons 4 et 3 ou 5 sont solidaires l'un de l'autre et forment une seconde partie de l'ensemble modulaire 1, mais sont libres de tourner autour de l'axe transversal médian 7.These two links 3, 5 and the central link 4 each comprise a second transverse guide opening 3b, respectively 4b, 5b which passes through their respective offset portions relative to the median transverse axis 7 and all three at the same distance from this axis. One of the links 3, 5 is integral with the adjacent lateral link 2 or 6, while the other of these links 3, 5 is integral with the central link 4. As the two lateral links 2, 6 are driven on the link axis 7 and that one of them is integral with the adjacent link 3 or 5, three links are integral with the median transverse axis 7 and form a first part of the modular assembly 1. The other two links 4 and 3 or 5 are integral with each other and form a second part of the modular assembly 1, but are free to rotate about the median transverse axis 7.

A noter que les deux paires de maillons adjacents solidaires l'un de l'autre, peuvent être réalisées à partir de deux pièces soudées ou fixées de toute autre manière appropriée l'une à l'autre. Ces deux paires de maillons solidaires pourraient aussi être directement constituées chacune d'une seule pièce, ne donnant alors que l'apparence d'être réalisée à partir de deux pièces assemblées. Toutefois, compte tenu du fait que le bracelet obtenu donne l'apparence d'être formé de cinq rangées longitudinales de maillons décalés alternativement dans le sens longitudinal, pour simplifier les explications, on les considèrera comme deux maillons solidaires, même si en réalité ils sont directement formés d'une seule pièce.Note that the two pairs of adjacent links integral with each other, can be made from two pieces welded or fixed in any other suitable manner to one another. These two pairs of integral links could also be directly constituted each of a single piece, giving then only the appearance of being made from two pieces assembled. However, given the fact that the bracelet obtained gives the appearance of being formed of five longitudinal rows of links alternately offset in the longitudinal direction, to simplify the explanations, they will be considered as two solidarity links, even if in reality they are directly formed of a single piece.

Comme le maillon central 4 et l'un des maillons 3, 5, dans cet exemple le maillon 3, qui sont solidaires l'un de l'autre sont libres de tourner autour de l'axe transversal médian 7, une fois l'ensemble modulaire 1 assemblé, comme illustré par la figure 2, ces maillons 3, 4 peuvent être tournés d'environ 90° autour de l'axe transversal médian 7, comme illustré par la figure 2, pour dégager l'ouverture transversale 4b de l'espace situé entre les maillons latéraux 2, 6 et permettre d'y accéder axialement, ce qui n'est pas possible lorsqu'elle se trouve dans l'espace situé entre les maillons latéraux 2, 6.As the central link 4 and one of the links 3, 5, in this example the link 3, which are integral with each other are free to rotate around the median transverse axis 7, once all modular 1 assembled, as illustrated by the figure 2 these links 3, 4 can be rotated about 90 ° around the median transverse axis 7, as illustrated by the figure 2 , to clear the transverse opening 4b of the space between the side links 2, 6 and allow access to it axially, which is not possible when it is in the space between the side links 2 , 6.

Une fois, cette ouverture transversale 4b placée comme illustré sur la figure 2, le maillon 4 peut être amené entre les maillons 3' et 5' de l'élément modulaire 1' qui se situe à l'extrémité avant de la portion de bracelet à laquelle doit être ajouté l'élément modulaire 1. L'ouverture transversale 4b du maillon 4 doit être alignée sur les ouvertures 3'b, 5'b des maillons 3', 5' de l'élément modulaire 1', ce qui permet la mise en place d'une tige transversale d'articulation 8, comme illustré par la figure 3.Once, this transverse opening 4b placed as illustrated on the figure 2 , the link 4 can be brought between the links 3 'and 5' of the modular element 1 'which is located at the front end of the strap portion to which the modular element 1 must be added. 4b of the link 4 must be aligned with the openings 3'b, 5'b of the links 3 ', 5' of the modular element 1 ', which allows the establishment of a transverse articulation rod 8, as illustrated by the figure 3 .

Pour bloquer transversalement cette tige transversale d'articulation 8, il faut basculer les deux maillons 3, 5 solidaires l'un de l'autre autour de l'axe transversal médian 7, jusqu'à ce que les ouvertures transversales de guidage 3b, 5b des maillons 3, 5 soient alignées transversalement. Dans cette position les deux parties 3, 5 de l'ensemble modulaire sont alignées, c'est-à-dire que leurs faces planes inférieures sont situées sur un même plan. Les faces latérales internes des maillons latéraux 2, 6 viennent se positionner contre les faces latérales adjacentes des maillons 3', respectivement 5', bouchant ainsi les extrémités des ouvertures transversales 3'b, 5'b et verrouillant ainsi axialement la tige transversale d'articulation 8.To lock transversely this transverse articulation rod 8, it is necessary to tilt the two links 3, 5 integral with one another about the median transverse axis 7, until the transverse guide openings 3b, 5b links 3, 5 are aligned transversely. In this position the two parts 3, 5 of the modular assembly are aligned, that is to say that their lower planar faces are located on the same plane. The internal lateral faces of the lateral links 2, 6 are positioned against the adjacent lateral faces of the links 3 ', respectively 5', thus plugging the ends transverse openings 3'b, 5'b and thus axially locking the transverse articulation rod 8.

Par la même occasion, une fois la tige transversale d'articulation 8 engagée dans les ouvertures transversales 3'b, 5'b des maillons 3' et 5', elle rend les deux parties, celle formée des maillons solidaires 3, 4 d'une part et celle formée des maillons 2, 5, 6 solidaires de l'axe 7 d'autre part, solidaires l'une de l'autre, en sorte que l'élément modulaire 1 forme alors un élément dont tous les maillons sont solidaires les uns des autres, seul la tige transversale d'articulation 8 assurant l'articulation des deux ensembles modulaires adjacents 1, 1'. Ainsi, chaque fois qu'une tige transversale d'articulation 8 relie les deux maillons 3, 5 appartenant respectivement aux deux parties d'un élément modulaire 1, susceptibles de tourner l'une par rapport à l'autre autour de l'axe de liaison 7, celles-ci sont immobilisées et ne forment plus alors qu'un seul ensemble modulaire articulé à l'ensemble modulaire adjacent autour du seul axe 8.At the same time, once the transverse articulation rod 8 engaged in the transverse openings 3'b, 5'b of the links 3 'and 5', it makes the two parts, that formed of the integral links 3, 4 of a part and the one formed of the links 2, 5, 6 integral with the axis 7 on the other hand, integral with each other, so that the modular element 1 then forms an element with all the links are integral from each other, only the transverse hinge rod 8 ensuring the articulation of the two adjacent modular assemblies 1, 1 '. Thus, each time a transverse hinge rod 8 connects the two links 3, 5 respectively belonging to the two parts of a modular element 1, capable of rotating relative to each other about the axis of link 7, these are immobilized and no longer form a single modular assembly articulated to the adjacent modular assembly about the single axis 8.

Par conséquent, étant donné que les ensembles modulaires 1, 1',..., pivotent chacun autour de la seule tige 8, les faces latérales internes des maillons latéraux 2, 6 qui jouent le rôle de butées axiales aux deux extrémités de cette tige 8, restent fixes par rapport à elle, l'empêchant de sortir des ouvertures transversales 3'b, 4b, 5'b ménagées dans les maillons 3', 4, 5' de deux ensembles modulaires 1, l'adjacents reliés par cette tige 8. L'assemblage devient dès lors indémontable.Therefore, since the modular assemblies 1, 1 ', ..., rotate each around the single rod 8, the inner side faces of the side links 2, 6 which act as axial stops at both ends of this rod 8, remain fixed relative to it, preventing it from leaving the transverse openings 3'b, 4b, 5'b formed in the links 3 ', 4, 5' of two modular assemblies 1, the adjacent connected by this rod 8. The assembly becomes therefore indémontable.

Le bracelet peut être démonté, mais en partant toujours de l'extrémité par laquelle le montage des ensembles modulaires 1, 1',..., s'est terminé. On commence par enlever la dernière tige transversale d'articulation 8 mise en place pour permettre aux deux parties de l'ensemble modulaire 1, formées respectivement des maillons 2, 5, 6, solidaires de l'axe transversal médian 7 et des maillons 3, 4, de pivoter l'une par rapport à l'autre afin d'autoriser la sortie de la tige transversale d'articulation 8 suivante, pour séparer les deux ensembles modulaires 1, 1' adjacents. Les deux parties formées de deux, respectivement trois maillons solidaires de l'axe transversal médian 7 de chaque ensemble modulaire 1 sont ainsi libérées l'une de l'autre au fur et à mesure, permettant le démontage successif de tous les ensembles modulaires 1, 1',... .The bracelet can be disassembled, but still starting from the end by which the assembly of the modular assemblies 1, 1 ', ..., has ended. We first remove the last transverse articulation rod 8 set up to allow the two parts of the modular assembly 1, formed respectively of the links 2, 5, 6, integral with the median transverse axis 7 and the links 3, 4, to pivot relative to each other in order to allow the output of the transverse articulation rod 8 next, to separate the two adjacent modular assemblies 1, 1 '. The two parts formed of two, respectively three links integral with the median transverse axis 7 of each modular assembly 1 and are released from one another as and when, allowing the successive disassembly of all modular assemblies 1, 1 ', ....

Pour relier le premier ensemble modulaire 1, par exemple à un boîtier de montre (non représenté) et étant donné qu'il n'est plus possible d'accéder à l'ouverture transversale 4b du maillon central 4 une fois que les deux parties susmentionnées formant l'ensemble modulaire 1, 1' ont été immobilisées par la tige transversale d'articulation 8, nous allons donner ici, à titre d'exemple, une solution possible pour éviter de devoir démonter le bracelet. L'une d'elles est illustrée ici par la figure 5.To connect the first modular assembly 1, for example to a watch case (not shown) and since it is no longer possible to access the transverse opening 4b of the central link 4 once the two aforementioned parts forming the modular assembly 1, 1 'have been immobilized by the transverse articulation rod 8, we will give here, as an example, a possible solution to avoid having to disassemble the bracelet. One of them is illustrated here by the figure 5 .

A cet effet, au début du montage du bracelet, on peut commencer par relier le premier ensemble modulaire 1 à un organe de liaison 9 qui comporte un passage 10 destiné à recevoir une barrette de fixation (non représentée) aux cornes d'une boîte de montre (non représentée) entre lesquelles l'organe de liaison 9 est ajusté, la largeur de cet organe de liaison 9 correspondant à l'écartement entre les cornes de la boîte et sa face 9a adjacente à la face externe de la boîte épousant le contour de celle-ci, de sorte que lorsque la barrette disposée dans le passage 10 est fixée aux cornes de la boîte, cet organe de liaison 9 devient solidaire de cette dernière.For this purpose, at the beginning of the mounting of the bracelet, it is possible to start by connecting the first modular assembly 1 to a connecting member 9 which includes a passage 10 intended to receive a fastening bar (not shown) to the horns of a box. shows (not shown) between which the connecting member 9 is adjusted, the width of this connecting member 9 corresponding to the spacing between the horns of the box and its face 9a adjacent to the outer face of the box conforming to the contour of the latter, so that when the bar disposed in the passage 10 is fixed to the horns of the box, the connecting member 9 becomes integral with the latter.

Cet organe de liaison 9 comporte deux saillies 13 et 15 dont la forme, l'écartement et les dimensions correspondent aux maillons 3, 5 d'un ensemble modulaire 1, mais ces saillies 13, 15 sont solidaires de l'organe de liaison. Dans ces conditions, le maillon central 4 d'un ensemble modulaire 1 peut être introduit entre les deux saillies 13, 15 et fixé à ces saillies par une tige transversale d'articulation 8 identique à celle reliant tous les ensembles modulaires 1, 1',..., entre eux, passant à travers l'ouverture transversale 4b du maillon central 4 et des ouvertures coaxiales 13b, 15b traversant les saillies 13, respectivement 15. Une fois cette liaison effectuée, les ensembles modulaires 1, 1',..., suivants peuvent être ajoutés en les reliant les uns aux autres comme décrit précédemment en relation avec les figures 2-4.This connecting member 9 comprises two projections 13 and 15 whose shape, spacing and dimensions correspond the links 3, 5 of a modular assembly 1, but these projections 13, 15 are integral with the connecting member. Under these conditions, the central link 4 of a modular assembly 1 can be introduced between the two projections 13, 15 and fixed to these projections by a transverse articulation rod 8 identical to that connecting all the modular assemblies 1, 1 ', ..., between them, passing through the transverse opening 4b of the central link 4 and coaxial openings 13b, 15b passing through the projections 13, respectively 15. Once this connection is made, the modular assemblies 1, 1 ', .. ., following can be added by linking them to each other as described previously in relation to the Figures 2-4 .

Pour permettre le démontage du bracelet, la dernière tige transversale d'articulation 8, destinée dans le cas d'une montre bracelet, à relier le bracelet à un fermoir, sera avantageusement constituée, selon une première variante, comme illustré par la figure 6, par une barrette à ressort 18 de type connu, qui passe à travers les ouvertures 3b, 5b des maillons 3, respectivement 5. Cette barrette à ressort comporte au moins une extrémité 18a formée par un piston monté coulissant par rapport au corps de barrette 18 qui renferme un ressort à boudin (non visible) qui exerce une pression axiale constante sur le piston 18a tendant à le faire sortir du corps de barrette 18. L'autre extrémité 18b de cette barrette 18, qui peut aussi être formée par un piston coulissant, est introduite dans un logement 16 d'un organe de fixation en forme de maillon 6* solidaire d'une lame 14 d'un fermoir à boucle déployante 17. Le fond de ce logement 16 se termine par un trou borgne (non visible) dans lequel l'extrémité 18b de la barrette 18 s'engage. Une pression axiale exercée sur l'autre extrémité 18a permet de faire rentrer le ou les pistons solidaires des extrémités 18a, 18b dans le corps de la barrette 18 jusqu'à ce qu'une butée annulaire 18c, respectivement 18d bute contre le corps de barrette 18. La longueur raccourcie de la barrette 18 permet alors d'engager l'autre extrémité 18a dans un logement 12 d'un organe de fixation en forme de maillon 2* solidaire de la lame 14 du fermoir 17. En relâchant la pression axiale sur la barrette 18, son extrémité 18a s'engage dans un trou borgne situé au fond du logement 12, réalisant ainsi la fixation amovible du bracelet au fermoir 17.To allow disassembly of the bracelet, the last transverse articulation rod 8, intended in the case of a wristwatch, to connect the bracelet to a clasp, will be advantageously constituted, according to a first variant, as illustrated by the figure 6 , by a spring bar 18 of known type, which passes through the openings 3b, 5b of the links 3, respectively 5. This spring bar has at least one end 18a formed by a piston slidably mounted relative to the barrel body 18 which encloses a coil spring (not visible) which exerts a constant axial pressure on the piston 18a tending to get it out of the barrel body 18. The other end 18b of this bar 18, which can also be formed by a sliding piston , is introduced into a housing 16 of a fastener-shaped link 6 * integral with a blade 14 of a folding clasp 17. The bottom of this housing 16 ends with a blind hole (not visible) wherein the end 18b of the bar 18 engages. An axial pressure exerted on the other end 18a makes it possible to return the piston or pistons integral with the ends 18a, 18b in the body of the bar 18 until an annular abutment 18c, respectively 18d abuts against the barrel body 18. The shortened length of the bar 18 then allows to engage the other end 18a in a housing 12 of a fastener-shaped link 2 * secured to the blade 14 of the clasp 17. By releasing the axial pressure on the bar 18, its end 18a engages in a blind hole located at the bottom of the housing 12, thus achieving the detachable attachment of the bracelet to the clasp 17.

Chaque logement 16, 12 s'ouvre latéralement sur la face inférieure (celle tournée contre le bras du porteur) des maillons 2*, 6* solidaires de la lame 14 du fermoir 17 pour permettre d'accéder aux butées annulaires 18c, 18d en vue de rétracter axialement le ou les pistons 18a, 18b de la barrette pour détacher le bracelet du fermoir 17.Each housing 16, 12 opens laterally on the lower face (that turned against the wearer's arm) links 2 *, 6 * integral with the blade 14 of the clasp 17 to allow access to the annular stops 18c, 18d in order axially retract the piston or pistons 18a, 18b of the bar to detach the bracelet clasp 17.

A titre de variante et comme illustré par la figure 7, on peut éviter de devoir pratiquer les ouvertures latérales des logements 16, 12 qui apparaissent sur le revers du bracelet, en remplaçant la barrette 18 par une tige de liaison et d'articulation 11 dont une extrémité 11a est filetée, tandis que l'extrémité opposée présente une fente diamétrale 11b pour permettre de visser l'extrémité 11a dans un filetage ménagé dans le maillon 6* de la lame 14 du fermoir 17. Cette tige 11 passe également dans une ouverture transversale traversant l'autre maillon 2* solidaire de la lame 14 du fermoir 17, ainsi que dans les ouvertures 3b, 5b des maillons 3, respectivement 5 de l'extrémité du bracelet.As a variant and as illustrated by the figure 7 , one can avoid having to practice the lateral openings of the housings 16, 12 which appear on the reverse of the bracelet, replacing the bar 18 by a connecting rod and hinge 11, one end 11a is threaded, while the end opposite has a diametrical slot 11b to allow screwing the end 11a in a thread formed in the link 6 * of the blade 14 of the clasp 17. This rod 11 also passes through a transverse opening through the other link 2 * integral with the blade 14 of the clasp 17, as well as in the openings 3b, 5b of the links 3, respectively 5 of the end of the bracelet.

Dans la forme d'exécution du bracelet décrite en relation avec les figures 1 à 4, le bracelet croît à partir d'une extrémité en direction de l'autre extrémité.In the embodiment of the bracelet described in relation to the Figures 1 to 4 , the bracelet grows from one end towards the other end.

La variante illustrée par la figure 8 montre comment il est possible de faire croître ou de raccourcir le bracelet selon l'invention depuis ses deux extrémités. Il suffit pour cela de disposer deux ensembles modulaires 1, l'en symétrie miroir l'un par rapport à l'autre de part et d'autre d'un axe transversal du bracelet, avec leurs deux maillons alignés transversalement 3, 5, respectivement 3', 5' tournés vers les extrémités du bracelet, comme illustré par la figure 8. Ensuite on relie ces deux ensembles modulaires par deux maillons indépendants 3*, 5* disposés entre les maillons latéraux 2, 6 et le maillon central 4 de l'ensemble modulaire 1 et entre les maillons latéraux 2', 6' et le maillon central 4' de l'ensemble modulaire 1'. Ces maillons indépendants 3*, 5* sont reliés au maillon central 4, 4', des ensembles modulaires 1, respectivement 1' par deux tiges transversales d'articulation 8, qui seront verrouillées lorsque les maillons centraux 4, 4' des ensembles modulaires 1, respectivement 1' seront rendus solidaires de l'axe transversal médian 7 de chacun de ces ensembles modulaires 1, 1' par une tige transversale d'articulation 8, qui reliera leurs deux maillons 3, 5, respectivement 3', 5' alignés transversalement aux maillons centraux 4", 4"' de deux autres ensembles modulaires suivants 1", 1"', (non représentés). Grâce à cette variante, le bracelet peut donc croître dans les deux sens.The variant illustrated by the figure 8 shows how it is possible to grow or shorten the bracelet according to the invention from its two ends. It is enough for this to have two modular assemblies 1, the mirror symmetry with respect to each other on both sides of a transverse axis of the bracelet, with their two links aligned transversely 3, 5, respectively 3 ', 5 'turned towards the ends of the bracelet, as illustrated by the figure 8 . Then these two modular assemblies are connected by two independent links 3 *, 5 * arranged between the lateral links 2, 6 and the central link 4 of the modular assembly 1 and between the lateral links 2 ', 6' and the central link 4 'of the modular assembly 1'. These independent links 3 *, 5 * are connected to the central link 4, 4 ', modular assemblies 1, 1' respectively by two transverse articulation rods 8, which will be locked when the central links 4, 4 'of the modular assemblies 1 respectively 1 'will be made integral with the central transverse axis 7 of each of these modular assemblies 1, 1' by a transverse hinge rod 8, which connect their two links 3, 5, respectively 3 ', 5' aligned transversely to the central links 4 ", 4"'of two other following modular assemblies 1 ", 1"' (not shown). With this variant, the bracelet can grow in both directions.

Les figures 9 et 10 montrent une variante d'un élément de liaison 19 conformé pour venir se loger entre les cornes (non représentées) d'une boîte de montre, pour relier une extrémité du bracelet, en particulier selon la variante de la figure 8, à cette boîte de montre. A la différence de l'élément de liaison 9 de la figure 5, cet élément de liaison 19 est conçu en deux parties 19a, 19b susceptibles de pivoter l'une par rapport à l'autre autour d'une tige transversale d'articulation 20. Les extrémités de cette tige transversale d'articulation sont cannelées et chassées dans deux logements respectifs de deux maillons latéraux 21, 22, solidaires de la partie 19b.The Figures 9 and 10 show a variant of a connecting element 19 shaped to be housed between the horns (not shown) of a watch case, to connect one end of the bracelet, in particular according to the variant of the figure 8 at this watch box. Unlike the link element 9 of the figure 5 this connecting element 19 is designed in two parts 19a, 19b pivotable relative to each other about a transverse pivot rod 20. The ends of this transverse articulation rod are fluted and driven in two respective housings of two lateral links 21, 22 integral with the part 19b.

La partie 19a comporte trois éléments 23, 24 et 25 assemblés par une tige transversale 26 chassée. La partie 19b comporte quatre éléments 21, 22, 27, 28 assemblés par deux tiges, 20, 29. Etant donné que l'élément 24 de la partie 19a est monté pivotant autour de la partie centrale de la tige transversale d'articulation 20, les deux parties 19a, 19b peuvent pivoter l'une par rapport à l'autre, permettant de faire basculer l'élément 24 pour faire sortir le passage transversal 24b de sa partie 24a de l'espace interne délimité par les parois latérales internes des maillons latéraux 21, 22 pour amener ce passage entre les deux maillons alignés transversalement 3, 5 d'un ensemble modulaire 1, par exemple celui de la figure 8, afin d'introduire la tige transversale d'articulation 8 à travers les passages transversaux 3b, 24b, 5b de ces trois maillons 3, 24a et 5.The portion 19a comprises three elements 23, 24 and 25 assembled by a transverse rod 26 driven. The part 19b comprises four elements 21, 22, 27, 28 assembled by two rods, 20, 29. Since the element 24 of the part 19a is pivotally mounted around the central part of the transverse articulation rod 20, the two parts 19a, 19b can pivot relative to each other, to tilt the element 24 to extend the transverse passage 24b of its portion 24a of the internal space delimited by the internal side walls of the links 21, 22 to bring this passage between the two transversely aligned links 3, 5 of a modular assembly 1, for example that of the figure 8 , in order to introduce the transverse articulation rod 8 through the transverse passages 3b, 24b, 5b of these three links 3, 24a and 5.

Le verrouillage des deux parties 19a, 19b autour de la tige transversale d'articulation 20 est réalisé lorsqu'une barrette (non représentée) est introduite au travers des passages transversaux 27c, 28c, 25c, 24c, 26c et 23c alignés sur l'axe de cette barrette, dont les deux extrémités viennent se loger, de manière habituelle, dans des ouvertures appropriées ménagées dans les faces latérales internes de ces cornes. Dans cette position, la tige transversale d'articulation 8 entre le dernier ensemble modulaire 1 et l'élément de liaison 19 bute à ses deux extrémités contre les faces latérales internes des maillons latéraux 21, 22 de l'élément de liaison 19 et est ainsi verrouillée.The locking of the two parts 19a, 19b around the transverse pivot rod 20 is performed when a bar (not shown) is introduced through the transverse passages 27c, 28c, 25c, 24c, 26c and 23c aligned on the axis of this bar, whose two ends are housed, in the usual way, in appropriate openings in the inner side faces of these horns. In this position, the transverse articulation rod 8 between the last modular assembly 1 and the connecting element 19 abuts at its two ends against the inner lateral faces of the lateral links 21, 22 of the connecting element 19 and is thus locked.

Il va sans dire que si, dans la forme d'exécution illustrée par les figures 1 à 4 on a montré un bracelet dont les ensembles modulaires sont assemblés d'une extrémité gauche à une extrémité droite, il est possible d'inverser le sens de cet assemblage.It goes without saying that if, in the form of execution illustrated by the Figures 1 to 4 we showed a bracelet whose modular sets are assembled from a left end at a right end, it is possible to reverse the direction of this assembly.

La forme d'exécution et les variantes décrites précédemment se rapportent toutes à un bracelet à cinq maillons. Toutefois, comme on a pu le constater, du point de vue fonctionnel, ces cinq maillons forment en réalité deux parties dont tous les éléments sont solidaires les uns des autres, de sorte que l'on a en réalité un ensemble modulaire formé de deux parties, comme dans les formes d'exécution précédentes comportant 5 maillons côte à côte.The embodiment and variants described above all relate to a bracelet with five links. However, as we have seen, from the functional point of view, these five links actually form two parts, all elements of which are integral with each other, so that we actually have a modular assembly formed of two parts. as in previous embodiments having 5 side-by-side links.

La variante illustrée par les figures 11 et 12 montre comment le concept de la présente invention peut être utilisé dans le cas d'un bracelet comportant des ensembles modulaires de quatre maillons solidaires deux à deux. Comme on peut le voir sur la figure 11, chaque ensemble modulaire 31, 31', 31", comporte deux parties 32, 33 disposées en symétrie miroir par rapport à un axe longitudinal médian du bracelet. Chaque partie 32, 33 comporte deux maillons 34, 35, respectivement 36, 37, formée ici d'une seule pièce, de sorte que ces parties comportent chacune une portion interne formée par les maillons 35, respectivement 36 et une portion externe, formée par les maillons 34, respectivement 37.The variant illustrated by Figures 11 and 12 shows how the concept of the present invention can be used in the case of a bracelet comprising modular assemblies of four links integral two by two. As can be seen on the figure 11 each modular assembly 31, 31 ', 31 "comprises two parts 32, 33 arranged in mirror symmetry with respect to a median longitudinal axis of the bracelet, each part 32, 33 comprising two links 34, 35, respectively 36, 37, formed here in one piece, so that these parts each comprise an inner portion formed by the links 35, respectively 36 and an outer portion, formed by the links 34, 37 respectively.

Les deux portions internes 35, 36 sont reliées indépendamment l'une de l'autre à l'axe transversal médian 38 par deux éléments tubulaires 39, 40 dont la longueur correspond à la dimension transversale de chaque portion interne 35, 36. Ces éléments tubulaires 39, 40 ont de préférence des surfaces externes cannelées et sont chassés dans des ouvertures 35a, respectivement 36a (non visible) des portions 35, respectivement 36. Ces éléments tubulaires 39, 40 sont retenus axialement sur l'axe transversal médian par rivetage aux deux extrémités de cet axe.The two inner portions 35, 36 are connected independently of one another to the median transverse axis 38 by two tubular elements 39, 40 whose length corresponds to the transverse dimension of each inner portion 35, 36. These tubular elements 39, 40 preferably have corrugated outer surfaces and are driven into openings 35a, respectively 36a (not visible) portions 35, respectively 36. These tubular elements 39, 40 are retained axially on the median transverse axis by riveting to both ends of this axis.

Une tige transversale d'articulation 41 est chassée dans une ouverture 34a ménagée dans la face latérale interne de l'une des portions externes 34, 37 de chaque ensemble modulaire 31, 31', 31" et sa longueur est choisie pour que l'extrémité libre de la tige transversale d'articulation 41 ne dépasse pas la face latérale interne de la portion externe 37, opposée à celle 34 dans laquelle cette tige 41 est fixée. Ainsi, selon le même concept inventif que celui décrit précédemment, la tige 41" qui se situe à gauche sur la figure 11 est verrouillée dans la position illustrée sur cette figure, dès que la tige 41' de l'ensemble modulaire 31' suivant est introduit dans les deux ouvertures de guidage 35"b, 36"b, mises coaxiales l'une à l'autre, des deux portions internes 35", 36" de l'ensemble modulaire 31", comme illustré par la figure 11. Ainsi, comme on le voit sur la figure 12, la mise en place des axes 41 des ensembles modulaires 31, 31', 31" provoque l'immobilisation des deux parties 32, 33 de ces ensembles modulaires et le verrouillage des tiges transversales 41 entre les deux portions externes 34, 37 des deux parties 32, 33, de ces ensembles modulaires 31, 31', 31", au fur et à mesure du montage successif de ces ensembles modulaires en allant de gauche à droite dans l'exemple décrit. De ce fait, les deux portions internes 35, 36 de chaque ensemble modulaire se trouvent aussi verrouillées sur ces tiges transversales 41 entre les deux faces latérales internes des portions externes 34, 37 de l'ensemble modulaire adjacent.A transverse articulation rod 41 is driven into an opening 34a formed in the internal lateral face of one of the outer portions 34, 37 of each modular assembly 31, 31 ', 31 "and its length is chosen so that the end free of the transverse articulation rod 41 does not exceed the inner lateral face of the outer portion 37, opposite that 34 in which the rod 41 is fixed.So, according to the same inventive concept as that described above, the rod 41 " which is left on the figure 11 is locked in the position illustrated in this figure, as soon as the rod 41 'of the following modular assembly 31' is introduced into the two guide openings 35 "b, 36" b, placed coaxial with each other, of the two inner portions 35 ", 36" of the modular assembly 31 ", as illustrated by FIG. figure 11 . So, as we see on the figure 12 , the establishment of the axes 41 of the modular assemblies 31, 31 ', 31 "causes the immobilization of the two parts 32, 33 of these modular assemblies and the locking of the transverse rods 41 between the two outer portions 34, 37 of the two parts 32, 33, of these modular assemblies 31, 31 ', 31 ", as and when successive assembly of these modular assemblies from left to right in the example described. As a result, the two inner portions 35, 36 of each modular assembly are also locked on these transverse rods 41 between the two inner lateral faces of the outer portions 34, 37 of the adjacent modular assembly.
