Description

La présente invention concerne un dispositif de réglage rapide entre au moins deux longueurs d'un bracelet, notamment un bracelet muni d'un fermoir à lames déployantes.The present invention relates to a quick adjustment device between at least two lengths of a bracelet, including a bracelet with a folding clasp.

L'homme du métier du domaine de la fabrication des bracelets, notamment pour montre-bracelet, sait que le diamètre du poignet humain varie en fonction de la température ambiante et de l'activité physique du porteur. Pendant la saison chaude et/ou durant une activité physique importante du porteur, le diamètre du poignet augmente alors que pendant la saison froide et /ou l'absence d'une activité physique ce diamètre diminue. On comprend donc la nécessité de pouvoir ajuster la longueur du bracelet pour l'adapter à ces différences de diamètre si l'on veut éviter, selon les circonstances, que le bracelet ne soit trop lâche autour du poignet ou encore qu'il serre de manière inconfortable le poignet du porteur.The person skilled in the field of the manufacture of bracelets, especially for a wristwatch, knows that the diameter of the human wrist varies according to the ambient temperature and the physical activity of the wearer. During the hot season and / or during a significant physical activity of the wearer, the diameter of the wrist increases while during the cold season and / or lack of physical activity this diameter decreases. We therefore understand the need to be able to adjust the length of the bracelet to adapt to these differences in diameter if we want to avoid, depending on the circumstances, that the bracelet is too loose around the wrist or that it tightens uncomfortable wrist of the wearer.

Alors que les bracelets en cuir à boucle et ardillon présentent généralement un nombre de trous suffisant pour s'ajuster suffisamment finement autour du poignet, les bracelets à maillons articulés sont ajustés en longueur par l'ajout ou le retrait d'un maillon à la chaîne les formant. Outre le fait que la finesse de l'ajustement en longueur est limitée à la longueur d'un maillon, une telle opération d'ajustement présente toutefois l'inconvénient de nécessiter l'intervention d'un spécialiste.While buckle and pin buckle leather bracelets generally have a sufficient number of holes to fit snugly around the wrist, articulated link bracelets are length-adjusted by adding or removing a chain link. forming them. In addition to the fact that the fineness of the adjustment in length is limited to the length of a link, such an adjustment operation however has the disadvantage of requiring the intervention of a specialist.

Divers systèmes ont été proposés jusqu'ici pour tenter de remédier à ce problème. On peut citer par exemple les documents CH 669 501 et FR 2 058 819 qui proposent des systèmes de réglage fin d'un bracelet. Toutefois, ces systèmes sont tous intégrés à un fermoir du type à lames, ou boucle, déployantes et mettent en oeuvre des dispositifs d'exécution compliqués et donc coûteux et par ailleurs peu souples d'utilisation.Various systems have been proposed so far to try to remedy this problem. Examples include documents CH 669 501 and FR 2 058 819 which offer fine adjustment systems of a bracelet. However, these systems are all integrated into a clasp of the blade type, or loop, deploying and implement complicated execution devices and therefore expensive and otherwise not flexible to use.

Pour s'affranchir de ces inconvénients, le document EP 0737 427 a proposé un maillon réglable en longueur indépendant d'un fermoir et pouvant être ainsi placé n'importe où dans un bracelet à maillons. Selon ce document, le maillon réglable comporte une coiffe dans laquelle coulisse une base et un mécanisme de poussoirs à ressort afin de permettre d'étendre le maillon selon plusieurs longueurs différentes. Les poussoirs présentent chacun une extrémité qui fait saillie sur les faces latérales du maillon et une extrémité opposée munie d'un cran coopérant avec des dents de deux crémaillères se faisant face et prévues dans la coiffe. Un système de type analogue et intégré dans un fermoir à lames déployantes est également décrit par le document US 5 749 128 .To overcome these drawbacks, the document EP 0737 427a proposed a link adjustable in length independent of a clasp and can be placed anywhere in a bracelet link. According to this document, the adjustable link comprises a cap in which slides a base and a mechanism of spring loaded pushers to allow the link to be extended in several different lengths. The pushers each have an end that protrudes from the side faces of the link and an opposite end provided with a notch cooperating with the teeth of two racks facing each other and provided in the cap. A similar type system and integrated into a folding clasp is also described by the document US 5,749,128 .

Bien que ce maillon et ce fermoir réglables permettent un ajustement satisfaisant de la longueur d'un bracelet dans lequel il est intégré, les poussoirs de commande sont apparents depuis l'extérieur et nuisent à l'esthétique générale du bracelet dans lequel ils sont intégré. En outre ces mécanismes d'ajustement comprennent respectivement un grand nombre de pièces ce qui les rend complexes et coûteux à mettre en oeuvre.Although this link and this adjustable clasp allow a satisfactory adjustment of the length of a bracelet in which it is integrated, the control buttons are visible from the outside and detract from the overall aesthetics of the bracelet in which they are integrated. In addition, these adjustment mechanisms respectively comprise a large number of parts, which makes them complex and expensive to implement.

Le document EP 819 391 décrit par ailleurs un dispositif de réglage de la longueur d'un bracelet muni d'un fermoir à lames déployantes dans lequel le réglage de la longueur s'effectue au moyen d'un maillon de réglage ayant deux axes d'articulation reliés respectivement à la coiffe du fermoir et à un maillon d'extrémité du bracelet. Le maillon de réglage peut pivoter par rapport à son axe relié à la coiffe du fermoir pour faire passer son axe relié au maillon d'extrémité de part et d'autre de l'axe relié à la coiffe pour définir deux longueurs déterminées. Le maillon d'extrémité relié au maillon de réglage présente une forme particulière qui permet dans la position du maillon de réglage correspondant à la longueur courte, de venir se bloquer de manière élastique sur le maillon de réglage. Selon ce dispositif l'écart entre la longueur courte et la longueur longue est déterminé par la distance entre les deux axes d'articulation du maillon de réglage, cet écart étant égal à deux fois cette distance. Le choix de cet écart de réglage de longueur est donc limité en pratique par des contraintes de construction du maillon de réglage qui ne peut être inférieur à 5mm. Par ailleurs ce dispositif présente l'inconvénient de ne permettre de choisir qu'entre deux longueurs déterminées.The document EP 819 391 further described a device for adjusting the length of a bracelet provided with a folding clasp in which the adjustment of the length is effected by means of a control link having two axes of articulation respectively connected to the clasp cap and at an end link of the bracelet. The adjustment link can pivot relative to its axis connected to the cap of the clasp to pass its axis connected to the end link on either side of the axis connected to the cap to define two specific lengths. The end link connected to the adjustment link has a particular shape which allows in the position of the adjustment link corresponding to the short length, to spring elastically on the adjusting link. According to this device the distance between the short length and the long length is determined by the distance between the two axes of articulation of the adjustment link, this difference being equal to twice this distance. The choice of this length adjustment gap is therefore limited in practice by construction constraints of the adjustment link which can not be less than 5 mm. Furthermore, this device has the disadvantage of only allowing to choose between two specific lengths.

Le document CH 667 979 décrit et représente un fermoir à lames déployantes dans lequel le maillon de réglage est articulé sur la coiffe du fermoir par l'intermédiaire d'une biellette dont l'axe d'articulation secondaire est monté coulissant sur le maillon de réglage. Toutefois, le dispositif de verrouillage décrit dans ce document comporte un mécanisme à poussoir relativement complexe et encombrant, et qui est pénalisant pour l'esthétique du bracelet.The document CH 667 979 describes and shows a clasp with folding blades in which the adjusting link is articulated on the cap of the clasp via a connecting rod whose secondary axis of articulation is slidably mounted on the adjusting link. However, the locking device described in this document comprises a relatively complex pusher mechanism and bulky, and which is detrimental to the aesthetics of the bracelet.

La présente invention a pour but principal de remédier aux inconvénients de l'art antérieur susmentionné en fournissant un dispositif de réglage de la longueur d'un bracelet permettant notamment un choix d'écart de réglage de la longueur du bracelet qui est indépendant de la distance entre les axes d'articulation du maillon de réglage sur la plaque de base. Ce dispositif de réglage doit aussi être compact pour pouvoir être intégré facilement dans un maillon de bracelet ou dans un fermoir à lames déployantes.The main object of the present invention is to overcome the drawbacks of the abovementioned prior art by providing a device for adjusting the length of a bracelet, in particular allowing a choice of distance to adjust the length of the bracelet which is independent of the distance. between the axes of articulation of the adjustment link on the base plate. This adjustment device must also be compact to be easily integrated in a bracelet link or in a folding clasp.

La présente invention a également pour but de fournir un dispositif de réglage de la longueur d'un bracelet qui peut être mis en oeuvre simplement par le porteur sans l'utilisation d'outil.The present invention also aims to provide a device for adjusting the length of a bracelet that can be implemented simply by the wearer without the use of tools.

La présenté invention a également pour but de fournir un dispositif de réglage de la longueur d'un bracelet de construction simple, sûre et peu coûteuse.The present invention also aims to provide a device for adjusting the length of a simple, safe and inexpensive construction bracelet.

A cet effet, l'invention propose un dispositif de réglage de la longueur d'un bracelet, notamment muni d'un fermoir à lames déployantes, prévu pour être intercalé globalement longitudinalement entre deux brins d'extrémité du bracelet, le dispositif de réglage comportant une plaque de base à une première extrémité longitudinale et un maillon de réglage à une seconde extrémité longitudinale, le maillon de réglage étant articulé sur la plaque de base par l'intermédiaire d'au moins une biellette qui est articulée, par une première extrémité, sur la plaque de base via un premier axe transversal d'articulation dit axe principal et qui est articulée, par une seconde extrémité, sur le maillon de réglage via un second axe transversal d'articulation dit axe secondaire, dans lequel le maillon de réglage est agencé de manière à coulisser relativement à la plaque de base selon la direction longitudinale du bracelet, comportant un dispositif de verrouillage permettant au maillon de réglage de s'accrocher sur un élément d'ancrage agencé sur la plaque de base selon au moins deux positions longitudinales indexées définissant respectivement deux longueurs de bracelet, caractérisé en ce que l'élément d'ancrage est disposé sur l'axe principal.For this purpose, the invention proposes a device for adjusting the length of a bracelet, in particular provided with a clasp with folding blades, designed to be inserted generally longitudinally between two end strands of the bracelet, the adjustment device comprising a base plate at a first longitudinal end and a control link at a second longitudinal end, the adjustment link being hinged to the base plate by means of at least one link which is articulated by a first end, on the base plate via a first transverse axis of articulation said main axis and which is articulated, by a second end, on the control link via a second transverse axis of articulation called secondary axis, wherein the control link is arranged so as to slide relative to the base plate in the longitudinal direction of the bracelet, comprising a locking device permitting the attachment link on an anchoring element arranged on the base plate in at least two indexed longitudinal positions respectively defining two lengths of a bracelet, characterized in that the anchoring element is arranged on the main axis.

Grâce à ces caractéristiques, le porteur du bracelet peut passer aisément, sans habileté ni outil particulier, d'une première longueur de bracelet à au moins une seconde longueur de bracelet. L'écart entre les différentes longueurs est de l'ordre de quelques millimètres et permet ainsi de compenser de manière précise les variations de pourtour du poignet provoquées notamment par la chaleur ambiante et ainsi d'améliorer le confort au porté du bracelet en toutes circonstances.Thanks to these characteristics, the wearer of the bracelet can pass easily, without skill or particular tool, a first length of bracelet to at least a second length of bracelet. The difference between the different lengths is of the order of a few millimeters and thus makes it possible to compensate in a precise manner the variations of circumference of the wrist caused in particular by the ambient heat and thus to improve the wearing comfort of the wristband in all circumstances.

Dans un mode de réalisation préféré, le maillon de réglage est articulé sur la plaque de base par l'intermédiaire de deux biellettes qui sont agencées de part et d'autre de ses extrémités transversales, ce qui facilite la réalisation d'un dispositif de réglage compact et rigide, notamment en torsion.In a preferred embodiment, the adjustment link is articulated on the base plate by means of two links which are arranged on either side of its transverse ends, which facilitates the production of an adjustment device. compact and rigid, especially in torsion.

Dans un mode de réalisation avantageux, l'élément d'ancrage peut être constitué par le tronçon médian d'une goupille principale qui est fixée sur la plaque de base et qui constitue l'axe principal, chaque biellette étant articulée sur un tronçon d'extrémité transversale de la goupille principale. Le même élément sert ainsi à l'articulation des biellettes et au verrouillage du maillon de réglage. De plus, la plaque de base peut comporter plusieurs paires de logements en vis-à-vis qui sont réparties en plusieurs positions longitudinales et qui sont prévues pour recevoir les deux extrémités de la goupille principale de manière à permettre un réglage supplémentaire de la longueur du bracelet en modifiant la position longitudinale de l'axe principal sur la plaque de base.In an advantageous embodiment, the anchoring element may be constituted by the median section of a main pin which is fixed on the base plate and which constitutes the main axis, each rod being hinged on a section of transverse end of the main pin. The same element thus serves for the articulation of the rods and the locking of the adjustment link. In addition, the base plate may comprise several pairs of housings vis-à-vis which are distributed in several longitudinal positions and which are provided to receive the two ends of the main pin so as to allow further adjustment of the length of the bracelet by changing the longitudinal position of the main axis on the base plate.

Dans un mode de réalisation préféré, le dispositif de verrouillage comporte au moins deux encoches aménagées dans le maillon de réglage destinées à coopérer par emboîtement avec l'élément d'ancrage. L'emboîtement est de préférence de type élastique. Ces encoches sont venues de matière avec le maillon de réglage, ce qui permet de réaliser le dispositif de verrouillage avec le minimum de pièces et la meilleure compacité.In a preferred embodiment, the locking device comprises at least two notches arranged in the adjusting link intended to cooperate by interlocking with the anchoring element. The interlocking is preferably of elastic type. These notches are made of material with the adjusting link, which allows to realize the locking device with the minimum of parts and the best compactness.

Dans un mode de réalisation préféré, le maillon de réglage comporte un trou oblong longitudinal, et l'axe secondaire est constitué par une goupille secondaire qui est fixée sur les biellettes et qui est reçue à coulissement dans le trou oblong. Ainsi, le coulissement est obtenu sans ajout de pièces supplémentaires.In a preferred embodiment, the adjustment link comprises a longitudinal oblong hole, and the secondary axis is constituted by a secondary pin which is fixed on the rods and which is slidably received in the oblong hole. Thus, the sliding is obtained without adding additional parts.

Avantageusement, le dispositif de réglage peut comporter au moins un élément de blocage qui restreint le pivotement des biellettes autour de l'axe principal dans un secteur angulaire déterminé, de préférence inférieur ou égal à quatre-vingt-dix degrés, ce qui permet d'empêcher le retournement des biellettes dans le sens d'un éloignement du maillon de réglage par rapport à l'axe principal.Advantageously, the adjusting device may comprise at least one blocking element which restricts the pivoting of the links around the main axis in a given angular sector, preferably less than or equal to ninety degrees, which makes it possible to prevent the rollover of the rods in the direction of a distance from the adjustment link relative to the main axis.

De préférence, dans au moins une des positions longitudinales indexées du maillon de réglage, une extrémité longitudinale du maillon de réglage est sensiblement alignée avec l'extrémité longitudinale d'une biellette, pour améliorer la compacité du dispositif de verrouillage.Preferably, in at least one of the indexed longitudinal positions of the adjusting link, a longitudinal end of the adjusting link is substantially aligned with the longitudinal end of a link, to improve the compactness of the locking device.

Selon un mode de réalisation avantageux, le maillon de réglage est articulé sur la face intérieure de la plaque de base, du côté du poignet qui porte le bracelet, ce qui permet de dissimuler le dispositif de verrouillage du côté intérieur du bracelet.According to an advantageous embodiment, the adjustment link is articulated on the inner face of the base plate, on the side of the wrist that carries the bracelet, which makes it possible to conceal the locking device on the inside of the bracelet.

De préférence, la plaque de base est constituée par la coiffe d'un fermoir à lames déployantes.Preferably, the base plate is constituted by the cap of a folding clasp.

La présente invention propose aussi un bracelet, notamment pour une montre portée au poignet, caractérisé en ce qu'il comporte un dispositif de réglage de sa longueur selon l'une des caractéristiques précédentes.The present invention also proposes a bracelet, in particular for a watch worn on the wrist, characterized in that it comprises a device for adjusting its length according to one of the preceding characteristics.

Sur la figure 1, on a représenté une montre-bracelet 10 qui est réalisée conformément aux enseignements de l'invention.In Figure 1, there is shown a wristwatch 10 which is made according to the teachings of the invention.

La montre-bracelet 10 comporte un boîtier 12 contenant un mouvement et un système d'affichage, et un bracelet 14 qui est fixé de part et d'autre du boîtier 12.The wristwatch 10 comprises a housing 12 containing a movement and a display system, and a bracelet 14 which is fixed on either side of the housing 12.

Le bracelet 14 est ici du type à maillons articulés et il est équipé d'un fermoir 16 à lames déployantes. Ce type de fermoir 16 étant bien connu de l'homme du métier, il ne fera pas l'objet d'une description détaillée.The bracelet 14 is here articulated link type and it is equipped with a clasp 16 folding blades. This type of clasp 16 is well known to those skilled in the art, it will not be the subject of a detailed description.

Selon la représentation de la figure 2, le fermoir 16 comporte deux lames 18, 20 superposables qui sont articulées l'une par rapport à l'autre à l'une de leurs extrémités, l'autre extrémité étant articulée respectivement sur un premier maillon d'extrémité 22 du bracelet 14 et sur une plaque de base dite coiffe 24 liée à un second maillon d'extrémité 26 du bracelet 14.According to the representation of Figure 2, the clasp 16 comprises two superposable blades 18, 20 which are articulated with respect to one another at one of their ends, the other end being articulated respectively to a first link of end 22 of the bracelet 14 and on a base plate called cap 24 linked to a second end link 26 of the bracelet 14.

Un dispositif de réglage 28 de la longueur du bracelet 14 est intercalé globalement longitudinalement entre deux brins d'extrémité du bracelet 14 constitués ici par une lame 20 et par le second maillon d'extrémité 26, la coiffe 24 appartenant au dispositif de réglage 28.A device 28 for adjusting the length of the band 14 is inserted longitudinally longitudinally between two end strands of the band 14 here constituted by a blade 20 and by the second end link 26, the cap 24 belonging to the adjusting device 28.

Dans la suite de la description, on utilisera à titre non limitatif une orientation globalement longitudinale qui correspond à la direction générale du bracelet 14 dans le sens de sa longueur et une orientation transversale globalement orthogonale à la direction longitudinale. On utilisera aussi à titre non limitatif les termes "intérieur" et "extérieur" pour qualifier des éléments selon qu'ils sont situés du côté du poignet portant le bracelet 14 ou du côté opposé audit poignet.In the remainder of the description, use will be made without limitation of a generally longitudinal orientation which corresponds to the general direction of the bracelet 14 in the direction of its length and a transverse orientation generally orthogonal to the longitudinal direction. The terms "inside" and "outside" will also be used in a nonlimiting manner to describe elements according to whether they are situated on the side of the wrist bearing the bracelet 14 or the side opposite the wrist.

En plus de la coiffe 24, le dispositif de réglage 28 comporte un maillon de réglage 30 qui est articulé sur le second maillon d'extrémité 26. Le maillon de réglage 30 est articulé sur la coiffe 24 par l'intermédiaire de deux biellettes 32, 34 qui sont agencées parallèlement de part et d'autre de ses extrémités transversales. Chaque biellette 32, 34 est articulée, par une première extrémité longitudinale, sur la coiffe 24 via un premier axe transversal d'articulation dit axe principal A1 et, par une seconde extrémité longitudinale, sur le maillon de réglage via un second axe transversal d'articulation dit axe secondaire A2.In addition to the cap 24, the adjusting device 28 comprises an adjusting link 30 which is articulated on the second end link 26. The adjusting link 30 is articulated on the cap 24 by means of two links 32, 34 which are arranged parallel to each other on both sides of its transverse ends. Each rod 32, 34 is articulated, by a first longitudinal end, on the cap 24 via a first transverse axis of articulation called main axis A1 and, by a second longitudinal end, on the control link via a second transverse axis of articulation called secondary axis A2.

Bien entendu, selon une variante de réalisation (non représentée) de l'invention, le maillon de réglage 30 peut être articulé sur la coiffe 24 par l'intermédiaire d'une seul biellette.Of course, according to an alternative embodiment (not shown) of the invention, the adjusting link 30 can be articulated on the cap 24 by means of a single link.

Avantageusement, l'axe principal A1 est constitué par une goupille principale 36 qui s'étend du côté de la face intérieure 38 de la coiffe 24, entre deux ailes longitudinales 40, 42 venues de matière avec la coiffe 24. A cet effet, la coiffe 24 comporte une paire de logements 44 aménagés dans les ailes en vis-à-vis et prévus pour recevoir les extrémités de la goupille principale 36. De préférence, la coiffe 24 comporte plusieurs paires de logements 44 décalés longitudinalement les unes par rapport aux autres, de manière à permettre un réglage supplémentaire de la longueur du bracelet 14 en modifiant la position longitudinale de la goupille principale 36.Advantageously, the main axis A1 is constituted by a main pin 36 which extends on the side of the inner face 38 of the cap 24, between two longitudinal wings 40, 42 integral with the cap 24. For this purpose, the cap 24 comprises a pair of housings 44 arranged in the wings vis-à-vis and provided to receive the ends of the main pin 36. Preferably, the cap 24 has several pairs of housing 44 offset longitudinally relative to each other , so as to allow further adjustment of the length of the bracelet 14 by changing the longitudinal position of the main pin 36.

Le maillon de réglage 30 est agencé de manière à coulisser relativement à la coiffe 24 selon une direction globalement longitudinale. Selon le mode de réalisation représenté ici, le maillon de réglage 30 a globalement la forme d'une plaque longitudinale de profil oblong. Dans son épaisseur, le maillon de réglage 30 comporte un trou oblong 46 longitudinal prévu pour recevoir à coulissement une goupille secondaire 48 qui est fixée sur les biellettes 32, 34 et qui forme l'axe secondaire A2 d'articulation. Le trou oblong 46 est traversant et il débouche dans les deux faces 50, 52 d'extrémité transversale du maillon de réglage 30.The adjusting link 30 is arranged to slide relative to the cap 24 in a generally longitudinal direction. According to the embodiment shown here, the adjustment link 30 has the overall shape of a longitudinal plate oblong profile. In its thickness, the adjustment link 30 comprises a longitudinal oblong hole 46 designed to slidably receive a secondary pin 48 which is fixed on the links 32, 34 and which forms the secondary articulation axis A2. The oblong hole 46 is through and opens into both transverse end faces 50, 52 of the adjusting link 30.

Le trou oblong 46 s'étend dans une première portion d'extrémité longitudinale du maillon de réglage 30. Dans une seconde portion d'extrémité longitudinale, le maillon de réglage 30 comporte une encoche de montage 54 et un logement 56 pour permettre sa fixation et son articulation sur le second maillon d'extrémité 26 du bracelet 14.The oblong hole 46 extends in a first longitudinal end portion of the adjusting link 30. In a second longitudinal end portion, the adjustment link 30 includes a mounting slot 54 and a housing 56 for allow its fixing and articulation on the second end link 26 of the bracelet 14.

Selon des variantes de réalisation (non représentées) de l'invention, le trou oblong 46 peut être réalisé dans les biellettes 32, 34 de manière, soit que l'axe secondaire A2 soit fixé sur le maillon de réglage 30 et qu'il coulisse par rapport aux biellettes 32, 34, soit que l'axe secondaire A2 soit fixe par rapport aux biellettes 32, 34 et au maillon de réglage 30 et que l'axe principal A1 soit reçu dans le trou oblong 46 pour permettre aux biellettes 32, 34 de coulisser par rapport à l'axe principal A1.According to alternative embodiments (not shown) of the invention, the oblong hole 46 can be made in the rods 32, 34 so that the secondary axis A2 is fixed on the adjusting link 30 and that it slides relative to the rods 32, 34, that the secondary axis A2 is fixed relative to the rods 32, 34 and the adjusting link 30 and that the main axis A1 is received in the oblong hole 46 to allow the rods 32, 34 slide relative to the main axis A1.

Le dispositif de réglage 28 comporte aussi un dispositif de verrouillage 58 qui permet au maillon de réglage 30 de s'accrocher sur un élément d'ancrage 60 agencé sur la coiffe 24 selon au moins deux positions longitudinales indexées, dites position longue PI et position courte Pc, définissant respectivement deux longueurs de bracelet 14.The adjusting device 28 also comprises a locking device 58 which allows the adjusting link 30 to catch on an anchoring element 60 arranged on the cap 24 in at least two indexed longitudinal positions, said long position PI and short position. Pc, respectively defining two lengths of bracelet 14.

Conformément aux enseignements de l'invention, l'élément d'ancrage 60 est disposé sur l'axe principal A1 d'articulation. Plus précisément, l'élément d'ancrage 60 est constitué par un tronçon cylindrique fixe qui s'étend entre les deux biellettes 32, 34 et qui est coaxial à l'axe principal A1. Avantageusement, ce tronçon cylindrique est constitué par le tronçon médian de la goupille principale 36, ainsi la goupille principale 36 sert à la fois d'articulation pour le pivotement des biellettes 32, 34 et d'élément d'ancrage 60 pour le dispositif de verrouillage 58.According to the teachings of the invention, the anchoring element 60 is disposed on the main articulation axis A1. More specifically, the anchoring element 60 is constituted by a fixed cylindrical section which extends between the two links 32, 34 and which is coaxial with the main axis A1. Advantageously, this cylindrical section is constituted by the median section of the main pin 36, so the main pin 36 serves both as a hinge for the pivoting of the links 32, 34 and anchoring element 60 for the locking device. 58.

Une première encoche 62, correspondant à la position longue PI, et une seconde encoche 64, correspondant à la position courte Pc, sont aménagées dans une portion intermédiaire du maillon de réglage 30, entre la première et la seconde portions d'extrémité longitudinale, pour permettre l'accrochage du maillon de réglage 30 sur l'élément d'ancrage 60. Ces encoches 62, 64 sont constituées par deux rainures transversales qui sont aménagées dans une face longitudinale du maillon de réglage 30 et qui débouchent dans les faces d'extrémité transversale 50, 52 du maillon de réglage 30. Les encoches 62, 64 peuvent ainsi être réalisées venues de matière avec le maillon de réglage 30.A first notch 62, corresponding to the long position PI, and a second notch 64, corresponding to the short position Pc, are arranged in an intermediate portion of the adjusting link 30, between the first and the second longitudinal end portions, for allow the hooking of the adjusting link 30 on the anchoring element 60. These notches 62, 64 are constituted by two transverse grooves which are arranged in a longitudinal face of the adjusting link 30 and which open into the end faces transverse 50, 52 of the adjustment link 30. The notches 62, 64 can thus be made integrally with the adjusting link 30.

Selon un mode de réalisation préféré, la largeur de chaque encoche 62, 64, dans une direction longitudinale, est sensiblement égale au diamètre externe de l'élément d'ancrage 60 de manière à retenir longitudinalement l'élément d'ancrage 60 sur le maillon de réglage 30. Chaque encoche 62, 64 comporte au moins un bossage 66 provoquant un rétrécissement de largeur localisé qui permet un emboîtement élastique du maillon de réglage 30 sur l'élément d'ancrage 60. Cet emboîtement est obtenu par une déformation élastique de la goupille principale 36 au passage du bossage 66, ce dernier permettant de retenir la goupille principale 36 dans le fond de l'encoche 62, 64 correspondante.According to a preferred embodiment, the width of each notch 62, 64, in a longitudinal direction, is substantially equal to the external diameter of the anchoring element 60 so as to retain longitudinally the anchoring element 60 on the link 30. Each notch 62, 64 comprises at least one boss 66 causing a narrowing of localized width that allows an elastic interlocking of the adjusting link 30 on the anchoring element 60. This interlocking is obtained by an elastic deformation of the main pin 36 at the passage of the boss 66, the latter for retaining the main pin 36 in the bottom of the notch 62, 64 corresponding.

Selon une variante de réalisation (non représentée) de l'invention, le maillon de réglage 30 peut comporter plus de deux encoches 62, 64.According to an alternative embodiment (not shown) of the invention, the adjusting link 30 may comprise more than two notches 62, 64.

Par inversion mécanique, on obtient une variante (non représentée) du dispositif de verrouillage 58 selon l'invention en réalisant l'élément d'ancrage 60 sous la forme d'une encoche ou d'un crochet, et en remplaçant les encoches 62, 64 du maillon de réglage 30 par des goupilles complémentaires de l'élément d'ancrage 60.By mechanical inversion, a variant (not shown) of the locking device 58 according to the invention is obtained by producing the anchoring element 60 in the form of a notch or a hook, and replacing the notches 62, 64 of the adjusting link 30 by complementary pins of the anchoring element 60.

On note que l'épaisseur du maillon de réglage 30 et des biellettes 32, 34 est ici sensiblement la même de sorte que, en position verrouillée, leurs faces extérieures sont globalement contenues dans un même plan longitudinal. Ainsi, grâce à la continuité de surface entre le maillon de réglage 30 et les biellettes 32, 34, on obtient un dispositif de réglage 28 particulièrement compact dans lequel le dispositif de verrouillage 58 est pratiquement invisible en position verrouillée.Note that the thickness of the adjusting link 30 and links 32, 34 is here substantially the same so that, in the locked position, their outer faces are generally contained in the same longitudinal plane. Thus, thanks to the surface continuity between the adjusting link 30 and the links 32, 34, a particularly compact adjustment device 28 is obtained in which the locking device 58 is practically invisible in the locked position.

On décrit maintenant le fonctionnement du dispositif de réglage 28 selon l'invention, notamment en référence aux figures 2 à 10 qui représentent le dispositif de réglage 28 dans plusieurs positions intermédiaires et dans ses positions indexées Pc, PI.The operation of the adjusting device 28 according to the invention is now described, in particular with reference to FIGS. 2 to 10, which represent the adjustment device 28 in several intermediate positions and in its indexed positions Pc, PI.

Sur les figures 2 et 3, le dispositif de réglage 28 est représenté verrouillé en position courte Pc. Les biellettes 32, 34 et le maillon de réglage 30 s'étendent alors longitudinalement dans un plan sensiblement parallèle à la face intérieure 38 de la coiffe 24, et le maillon de réglage 30 est accroché sur l'élément d'ancrage 60 par l'intermédiaire de la seconde encoche 64. On note que, dans cette configuration, la goupille secondaire 48 est sensiblement adjacente à l'extrémité du trou oblong 46 située du côté des encoches 62, 64. Les éléments servant au réglage de la longueur du bracelet 14 sont alors dissimulés sous la coiffe 24.In Figures 2 and 3, the adjustment device 28 is shown locked in the short position Pc. The rods 32, 34 and the adjusting link 30 then extend longitudinally in a plane substantially parallel to the inner face 38 of the cap 24, and the adjusting link 30 is hooked on the anchoring element 60 by the intermediate of the second notch 64. It is noted that, in this configuration, the secondary pin 48 is substantially adjacent to the end of the oblong hole 46 located on the side of the notches 62, 64. The elements used to adjust the length of the strap 14 are then concealed under the headdress 24.

On décrit maintenant le passage de la position courte Pc à la position longue PI, le réglage de la longueur du bracelet 14 étant effectué lorsque le fermoir 16 est ouvert.We now describe the transition from the short position Pc to the long position PI, the adjustment of the length of the bracelet 14 being performed when the clasp 16 is open.

L'utilisateur tire manuellement sur l'extrémité du maillon de réglage 30 où s'articule le second maillon d'extrémité 26 du bracelet 14, de manière à décrocher le maillon de réglage 30 de l'élément d'ancrage 60. Après le passage du point dur dû au passage du bossage 66 de verrouillage, le maillon de réglage 30 pivote vers l'intérieur autour de l'axe secondaire A2, dans le sens horaire en considérant la figure 4, et les biellettes 32, 34 pivotent vers l'intérieur autour de l'axe principal A1, dans le sens anti-horaire en considérant la figure 4, pour permettre au maillon de réglage 30 de s'éloigner de la face intérieure 38 de la coiffe 24. Le maillon de réglage 30 et les biellettes 32, 34 se trouvent alors dans la première configuration intermédiaire qui est représentée sur les figures 4 et 5.The user manually pulls on the end of the adjusting link 30 which articulates the second end link 26 of the bracelet 14, so as to unhook the adjusting link 30 of the anchoring element 60. After the passage of the hard point due to the passage of the locking boss 66, the adjusting link 30 pivots inward about the secondary axis A2, in a clockwise direction considering FIG. 4, and the links 32, 34 pivot towards the inside the main axis A1, counterclockwise considering Figure 4, to allow the adjusting link 30 to move away from the inner face 38 of the cap 24. The adjustment link 30 and the rods 32, 34 are then in the first intermediate configuration which is shown in Figures 4 and 5.

Pour allonger le bracelet 14, l'utilisateur provoque alors manuellement un coulissement longitudinal du maillon de réglage 30 par rapport à l'axe secondaire A2, globalement vers la droite dans le sens de la flèche F1 en considérant la figure 4, jusqu'à ce que la goupille secondaire 48 soit sensiblement adjacente à l'extrémité du trou oblong 46 située du côté opposé aux encoches 62, 64. Cette seconde configuration intermédiaire est représentée sur les figures 6 et 7.To lengthen the bracelet 14, the user then manually causes longitudinal sliding of the adjustment link 30 with respect to the secondary axis A2, generally to the right in the direction of the arrow F1 while considering FIG. 4, until that the secondary pin 48 is substantially adjacent to the end of the oblong hole 46 located on the side opposite to the notches 62, 64. This second intermediate configuration is shown in FIGS. 6 and 7.

A partir ce cette seconde configuration intermédiaire, l'utilisateur repousse le maillon de réglage 30 vers la coiffe 24 en faisant pivoter le maillon de réglage 30 et les biellettes 32, 34 en sens inverse de celui indiqué en référence aux figures 3 et 4, de manière à emboîter le maillon de réglage 30 sur l'élément d'ancrage 60 avec la première encoche 62, qui correspond à la position longue PI. Le maillon de réglage 30 occupe alors sa position longue PI dans laquelle, comme pour la position courte Pc, le maillon de réglage 30 et les biellettes 32, 34 s'étendent parallèlement dans un plan longitudinal.From this second intermediate configuration, the user pushes the adjustment link 30 towards the cap 24 by pivoting the adjustment link 30 and the rods 32, 34 in the opposite direction to that indicated with reference to FIGS. 3 and 4, of FIG. so as to fit the adjusting link 30 on the anchoring element 60 with the first notch 62, which corresponds to the long position PI. The adjusting link 30 then occupies its long position PI in which, as for the short position Pc, the adjusting link 30 and the rods 32, 34 extend parallel in a longitudinal plane.

La position longue PI est illustrée par les figures 8 et 9. Sur ces figures, on constate que le maillon de réglage 30 est décalé longitudinalement vers la droite, par rapport à la position courte Pc, d'une distance de réglage D égale à la distance D' entre le centre des deux encoches 62, 64. Typiquement, la distance de réglage D peut être de l'ordre de deux millimètres, ce qui permet un réglage fin de la longueur du bracelet 14 et assure un confort maximal à l'utilisateur.The long position PI is illustrated by FIGS. 8 and 9. In these figures, it can be seen that the adjustment link 30 is shifted longitudinally to the right, with respect to the short position Pc, by a setting distance D equal to distance D 'between the center of the two notches 62, 64. Typically, the adjustment distance D can be of the order of two millimeters, which allows a fine adjustment of the length of the strap 14 and ensures maximum comfort to the user.

On note que, dans les deux positions indexées Pc, PI, l'axe secondaire A2 se trouve positionné du même côté de l'axe primaire A1, du côté opposé au second maillon d'extrémité 26.It is noted that, in the two indexed positions Pc, P1, the secondary axis A2 is positioned on the same side of the primary axis A1, on the opposite side to the second end link 26.

Selon un mode de réalisation préféré, dans la position longue PI, l'extrémité longitudinale du maillon de réglage 30 située du côté du trou oblong 46 est sensiblement alignée transversalement avec l'extrémité longitudinale des biellettes 32, 34 située du côté de l'axe secondaire A2 et, dans la position courte Pc, le maillon de réglage 30 s'étend longitudinalement de manière symétrique de part et d'autre des biellettes 32, 34. Un tel agencement permet d'obtenir un dispositif de réglage 28 particulièrement compact et permet de dissimuler le dispositif de verrouillage 58.According to a preferred embodiment, in the long position PI, the longitudinal end of the adjusting link 30 located on the side of the oblong hole 46 is substantially aligned transversely with the longitudinal end of the rods 32, 34 located on the axis side. secondary A2 and, in the short position Pc, the adjusting link 30 extends longitudinally symmetrically on either side of the rods 32, 34. Such an arrangement provides a particularly compact adjustment device 28 and allows to conceal the locking device 58.

Le passage de la position longue PI à la position courte Pc s'effectue de manière similaire au passage de la position courte Pc à la position longue PI, en faisant coulisser le maillon de réglage 30 par rapport à l'axe secondaire A2 dans le sens inverse à la flèche F1 de la figure 4.The transition from the long position P1 to the short position Pc is performed in a manner similar to the transition from the short position Pc to the long position P1, by sliding the adjusting link 30 with respect to the secondary axis A2 in the direction inverse to the arrow F1 in FIG.

On note que, la position déverrouillée du maillon de réglage 30 peut constituer une position de réglage supplémentaire dans laquelle la longueur du bracelet 14 est plus grande que lorsque le maillon de réglage 30 occupe sa position longue Pl. En effet, en position déverrouillée, l'axe secondaire A2 peut passer de l'autre côté de l'axe principal A1, du côté du second maillon d'extrémité 26, ce qui allonge la longueur du bracelet 14.It will be noted that the unlocked position of the adjustment link 30 may constitute an additional adjustment position in which the length of the bracelet 14 is greater than when the adjustment link 30 is in its long position P1. Indeed, in the unlocked position, the secondary axis A2 can pass from the other side of the main axis A1, the side of the second end link 26, which lengthens the length of the bracelet 14.

Lorsque cette position de réglage supplémentaire n'est pas souhaitée, on prévoit un élément de blocage 68 (Figure 10) qui restreint le pivotement des biellettes 32, 34 autour de l'axe principal A1 dans un secteur angulaire déterminé, de préférence inférieur ou égal à quatre-vingt-dix degrés. Selon le mode de réalisation représenté sur les figures, l'élément de blocage 68 est constitué par une portion d'extrémité de chaque biellette 32, 34 qui vient en butée contre la face intérieure 38 de la coiffe 24 lorsque la biellette 32, 34 associée s'approche d'une position perpendiculaire à la coiffe 24.When this additional adjustment position is not desired, there is provided a locking element 68 (FIG. 10) which restricts the pivoting of the links 32, 34 around the main axis A1 in a given angular sector, preferably less than or equal to at ninety degrees. According to the embodiment shown in the figures, the locking element 68 is constituted by an end portion of each link 32, 34 which abuts against the inner face 38 of the cap 24 when the connecting rod 32, 34 associated approaching a position perpendicular to the cap 24.

Bien que l'invention ait été décrite dans le cadre d'un bracelet comportant un fermoir à lames déployantes, elle peut s'appliquer d'autres types de bracelet. L'invention est particulièrement adaptée aux bracelets à maillons articulés.Although the invention has been described in the context of a bracelet comprising a folding clasp, it can be applied to other types of bracelet. The invention is particularly suitable for articulated link bracelets.
