- This adjustment device is intended to allow the user to have, for each initial length of the bracelet set by a first conventional main adjustment means (adjustment means separate from the second adjustment means according to the embodiment of the invention ), a determined additional length, having a small fixed gap with the length initially set, to allow to pass easily, without skill or special tool, from one to the other strap length.
- the difference between these two lengths is chosen to take into account the differences in the circumference of the wrist according to the ambient heat and / or the efforts that the wearer of the bracelet makes with his arm and which result in swelling of the wrist.
- the adjustment device is associated with a folding clasp with two or three folding blades.
- it is compatible with a complex bracelet structure, for example a bracelet formed by a set of links interconnected by transverse axes, the number of links being chosen to define an initial setting substantially corresponding to the circumference of the wrist. of the user.
- Each link may comprise several meshes, juxtaposed in a transverse direction, comprising for example one or more mesh (s) inserted center (s) between edge meshes.
- Such a set is for example represented on the figure 8 .
- the adjustment device according to this embodiment is arranged at the end of a bracelet strand, at a clasp of which only a lid 2 is shown in phantom on the Figures 1 to 3s , to leave visible all the components of the adjustment device.
- the bracelet is composed of a succession of pairs of links 10, 11, each comprising respectively three meshes 10a, 10b, 10c and two meshes 11a, 11b.
- the first link 10 thus comprises three meshes, including two edge meshes 10b, 10c extending on the sides of the bracelet, and a center mesh 10a. These three meshes are interconnected by at least one transverse axis 12 passing through openings of these three meshes. These last have the same length and extend parallel in the longitudinal direction, and their two longitudinal ends are positioned at the same level.
- the width L10a of the center mesh 10a is less than or equal to that L10b, L10c of the two edge meshes 10b, 10c, of the same length in this embodiment.
- Such a first link 10 is associated, on each of its two longitudinal ends, with a second link 11 consisting of two meshes 11a, 11b. These two meshes 11a, 11b constitute center meshes. They are positioned to interpose between respectively the meshes 10a, 10b and 10a, 10c of the first link 10. Their end is mounted on an axis 12 connecting the three meshes 10a, 10b, 10c of the first link 10, in an articulated manner, leaving the two links 10, 11 free in relative rotation.
- the two meshes 11 a, 11 b of the second link 11 are substantially identical and have the same length and the same shape as the three meshes 10a, 10b, 10c of the first link 10 and their integrated end between two meshes of the first link is substantially in the middle of the length of the three meshes 10a, 10b, 10c.
- Their width is substantially the same, and substantially also the same as that of the center mesh 10a of the first link 10.
- the bracelet strand obtained is thus composed of five meshes juxtaposed parallel to the width of the bracelet, obtained by a succession of interposed links of respectively three meshes and two meshes, the two meshes being offset longitudinally with respect to said three adjacent meshes.
- This construction results in a very harmonious aesthetic appearance, in particular because of a large number of meshes articulated between them, and in particular center meshes of small width.
- this large number of stitches makes it possible to achieve a great wearing comfort of this bracelet, since the articulated stitches marry at best the contour of the wrist. This comfort decreases if the mesh size increases and / or the number of meshes is reduced.
- a regulating device in particular a comfort adjustment, of its length, shaped to allow a slight adjustment of the length of the bracelet, in addition to a conventional initial setting, as explained above.
- This adjustment device comprises an adjusting link 6, pivotally mounted about a first axis 5, formed by a transverse bar fixed laterally in two perforations 4 present on the side walls which face each other at the level of the cover 2, belonging to a clasp 1 to folding clasp.
- This adjustment link 6 implements the function of adjusting the length of the bracelet.
- this adjustment link 6 comprises a second hinge axis 7, composed of an axis not shown, on which is articulated a first end 8i of a second link, called end link 8, because its second end 8j is articulated at the end of the bracelet strand about a second axis 9.
- the adjustment link 6 is in the form of two edge meshes 6b, 6c connected by the two axes 5, 7 mentioned.
- the end link 8 is here in the form of a single mesh.
- the end link 8 has a first bore, at the first end 8i, provided to receive the axis 7 of the adjusting link. It has a width L8 less than the width L of the bracelet and clasp, so that its first end 8i carrying the first bore can be housed between the two edge meshes 6b, 6c of the adjusting link 6 when mounted around of the axis 7.
- This width L8 is equal to the sum of the widths of the three center stitches 11a, 10a, 11b of the bracelet.
- the end link 8 has a second bore, at a second end 8j, provided to receive the second axis 9, particularly visible on the figure 7 , in order to create the link with the link 10 consisting of three meshes 10a, 10b, 10c forming the end of the bracelet strand, which is bound.
- the end link 8 has at least one longitudinally extending cutout 8e, which is provided to receive a center mesh 10a of a link 10 of the bracelet strand, as will be detailed by the following.
- This cutout 8e positioned in the central part of the end link 8, delimits two parts 8a, 8b which include the curvature of the surface of the center stitches of the bracelet, in particular the two stitches 11a, 11b of a second link 11.
- This cut 8e can be formed by machining within the second end 8j of the end link 8, to finally have a shape delimited by two parallel plane side flanks, oriented in the vertical longitudinal direction, which substantially corresponds to the geometry of at least a portion of a center mesh of the bracelet, so that this mesh is housed with less clearance within the cutout, articulated manner around the second axis 9.
- this cutout 8e is through in the longitudinal direction on either side of the second end 8j of the end link 8.
- the two ends 8i, 8j of the end link 8, respectively carrying the two bores to receive the two axes 7, 9, are connected by a transverse cutout 8c of substantially semi-cylindrical shape. It further comprises an S-shaped wall 8d, substantially in the central position of this cutout 8c, the size of which is intended to be slightly smaller than the bar forming the first axis 5, so as to be able to snap elastically onto this axis 5 in a short configuration of the adjustment device.
- This wall 8d thus forms a narrowing at the entrance of the housing formed by the transverse cut 8c, the size of which is calculated to be slightly smaller than the corresponding dimension of the part of the axis 5 which must engage in the housing.
- This wall 8d thus serves as attachment means for the axis 5 when it is engaged elastically in this housing in short configuration of the adjustment device.
- This transversal cut 8c comes from more truncating the second end 8j of the end link, the two parts 8a, 8b lateral around the cut 8e take the form of half meshes 11a, 11b cut at their center by a transverse median plane.
- end link 8 is in one piece. Its two ends 8i, 8j are linked together in solidarity, with no movement. The end link 8 thus forms a monolithic piece. It comes in a monobloc form.
- the figure 1 represents the adjustment device in the short configuration.
- the adjusting link 6 is arranged so that its axis 7 is positioned towards the inside of the clasp, opposite the end of the bracelet with respect to its axis 5.
- the transverse cutout 8c of the link 8 end receives the central portion of the first axis 5 of the adjusting link 6, and the wall 8d is fixed on this axis and ensures the attachment of said end link 8 in this position, ensuring the stability of the short configuration of the adjustment device.
- the figure 2 represents an intermediate configuration, in which the adjusting link 6 began its rotation about its first axis 5, which represents an axis of articulation of the adjustment link relative to the cover of the clasp. In this illustration, it has made about a quarter turn, thus positioning its second axis 7 at the same longitudinal level as the axis 5, superimposed under this axis 5 relative to the lid 2.
- the figure 3 illustrates finally the long configuration of the bracelet, obtained when the adjusting link 6 has finalized its rotation about the axis 5, the second axis 7 returning to the same height as the axis 5, abutting under the cover 2.
- the link setting 6 then rotated substantially 180 degrees with respect to its first axis 5, and the second axis 7 is then positioned on the side of the bracelet strand with respect to this first axis 5.
- the adjustment device makes it possible to adjust the length between two determined bracelet lengths.
- the transition from one position to another is obtained only voluntarily, by simple manipulation, not requiring any particular skill of the user.
- the configuration of the adjustment device is obtained by a simple force exerted voluntarily on the end of his bracelet, in the desired direction of actuation, by the user.
- This set length is maintained as long as the user has not decided otherwise.
- the clasp can be opened and closed without the setting being changed. It may also be noted that in one or other of the length configurations, the height of the clasp remains unchanged, so that this device does not detract from the aesthetic appearance of the bracelet.
- FIGS. 5 and 6 illustrate the adjustment device in its short configuration. They make it possible to visualize the axis 9 mounted at the second end 8j of the end link 8, on which is mounted a first link 10 of three-link bracelet 10a, 10b, 10c, described above.
- these figures serve to illustrate the integration of the center mesh 10a in the central cutout 8e. Its lateral flanks come almost in contact with the lateral flanks of the cut, allowing its articulation with less play relative to the end link 8.
- the two parts 8a, 8b around the cut 8e are thus respectively positioned between the meshes 10a, 10b and 10a, 10c, in the manner of a second link 11 of the bracelet.
- the three meshes 10a, 10b, 10c of the link 10 are traversed by a second axis 12 intended to receive the articulated connection of a second link 11, the two meshes 11a, 11b of which would be in continuity with the two parts 8a, 8b of the end link 8, as is visible on the Figures 1 to 3 and 8 .
- the end link 8 makes it possible to link the link adjusting the length of the bracelet and the end of the bracelet, while ensuring the aesthetic integrity of the bracelet, in both configurations. short and long adjustment device, even in the example shown a complex architecture because of its many small meshes.
- this end link 8 ensures the comfort of the bracelet to its end.
- the figure 7 represents a cross-sectional view at the central portion of an axis 9. It shows the connection between the three meshes 10a, 10b, 10c of the bracelet and the end link 8.
- the axis 9 is driven into bores of the edge meshes 10b, 10c, and mounted with less clearance within the bore of the center mesh 10a.
- the solution according to the embodiment is particularly suitable for a bracelet comprising articulated links, and more particularly links comprising several meshes, including meshes of the center and edge, as explained above.
- the width of all or part of the center stitches 10a, 11a, 11b is less than or equal to that of an edge stitch 10b, 10c.
- the center mesh 10a of a link has a width L10a less than or equal to the width L10b of the first edge mesh 10b and / or less than or equal to the width L10c of the second edge mesh 10c ( figure 6 ).

Description
La présente invention concerne un dispositif de réglage de la longueur d'un bracelet, particulièrement adapté à un bracelet muni d'un fermoir à lames déployantes pour montre-bracelet, disposé entre deux extrémités du bracelet, pour former avec lui un lien sans fin dont la longueur peut varier entre deux dimensions. Elle porte aussi sur un fermoir et un bracelet en tant que tels, intégrant un tel dispositif de réglage, ainsi que sur une montre-bracelet en tant que telle comprenant un tel fermoir ou bracelet.The present invention relates to a device for adjusting the length of a bracelet, particularly adapted to a bracelet provided with a folding clasp for a wristwatch, arranged between two ends of the bracelet, to form with it an endless link of which the length can vary between two dimensions. It also relates to a clasp and a bracelet as such, incorporating such a setting device, as well as a wristwatch as such comprising such a clasp or bracelet.
Il existe plusieurs solutions pour accrocher les deux brins d'un bracelet de montre autour du poignet de son porteur. Dans tous les cas, cet accrochage est doté d'un moyen de réglage principal de la longueur du bracelet, pour l'adapter au pourtour du poignet de son porteur.There are several solutions for hanging the two strands of a watch strap around the wrist of its wearer. In all cases, this attachment has a means of main adjustment of the length of the bracelet, to adapt to the periphery of the wrist of the wearer.
Une solution courante de l'état de la technique consiste à prévoir un élément intermédiaire de type fermoir, disposé entre les deux brins de bracelet, qui reste toujours solidaire des extrémités de ces deux brins. Un tel fermoir occupe deux positions : une position fermée, prévue pour le port de la montre, dans laquelle le bracelet et le fermoir s'étendent sur le pourtour du poignet en présentant une longueur totale permettant le maintien de la montre-bracelet, et une position ouverte qui permet d'augmenter la longueur du bracelet et du fermoir, en écartant les deux extrémités des deux brins du bracelet, sans les détacher du fermoir, pour permettre le passage de la main et le retrait de la montre. Dans cette configuration ouverte du fermoir, les deux brins du bracelet ne sont pas désolidarisés, ce qui minimise le risque de chute de la montre. La longueur de chaque brin de bracelet est choisie pour correspondre au pourtour du poignet du porteur en position fermée du fermoir.A common solution of the state of the art is to provide an intermediate clasp type element disposed between the two bracelet strands, which is always secured to the ends of these two strands. Such a clasp occupies two positions: a closed position, intended for the wearing of the watch, in which the bracelet and the clasp extend around the circumference of the wrist with a total length allowing the wristwatch to be held, and a open position that increases the length of the bracelet and the clasp, by separating the two ends of the two strands of the bracelet, without detaching the clasp, to allow the passage of the hand and the removal of the watch. In this open configuration of the clasp, the two strands of the bracelet are not disconnected, which minimizes the risk falling from the watch. The length of each strand of bracelet is chosen to correspond to the periphery of the wrist of the wearer in the closed position of the clasp.
Dans tous les cas, il est important de permettre un réglage convivial de la longueur du bracelet, d'utilisation facile et efficace.In any case, it is important to allow a user-friendly adjustment of the length of the bracelet, easy and effective use.
En parallèle, il est aussi important de garantir l'intégrité esthétique du bracelet, notamment par la continuité harmonieuse de la structure et de l'apparence du bracelet, même lorsque ce dernier présente une structure relativement complexe, jusqu'aux extrémités des brins, par exemple au niveau d'un fermoir. En particulier, les composants participant au réglage de la longueur du bracelet ne doivent pas modifier l'aspect esthétique du bracelet.In parallel, it is also important to ensure the aesthetic integrity of the bracelet, in particular by the harmonious continuity of the structure and the appearance of the bracelet, even when the latter has a relatively complex structure, to the ends of the strands, by example at the level of a clasp. In particular, the components involved in adjusting the length of the bracelet must not change the aesthetic appearance of the bracelet.
Ainsi, le but général de la présente invention est de proposer une solution qui permet un réglage de la longueur d'un bracelet, notamment un réglage de confort de la longueur d'un bracelet, tout en assurant son intégrité esthétique.Thus, the general object of the present invention is to provide a solution that allows adjustment of the length of a bracelet, including a comfort adjustment of the length of a bracelet, while ensuring its aesthetic integrity.

Pour simplifier la description, nous utiliserons par convention les termes de « direction longitudinale » pour la direction selon la longueur d'un brin de bracelet, et de « direction transversale » pour la direction perpendiculaire, dans le plan d'un brin de bracelet (selon sa largeur). La direction verticale est la direction perpendiculaire aux deux premières directions, orientée perpendiculairement au plan du bracelet. D'autre part, nous utiliserons le terme de « maille » pour un composant élémentaire d'un bracelet, et le terme de « maillon » un groupe de mailles liées entre elles et disposées au même niveau longitudinal d'un bracelet.To simplify the description, we will use by convention the terms "longitudinal direction" for the direction along the length of a bracelet strand, and "transverse direction" for the perpendicular direction, in the plane of a bracelet strand ( according to its width). The vertical direction is the direction perpendicular to the first two directions, oriented perpendicular to the plane of the bracelet. On the other hand, we will use the term "mesh" for an elementary component of a bracelet, and the term "link" a group of links linked together and arranged at the same longitudinal level of a bracelet.
L'invention repose sur un dispositif de réglage de la longueur d'un bracelet. Ce dispositif de réglage a pour but de permettre à l'utilisateur de disposer, pour chaque longueur initiale du bracelet réglée par un premier moyen de réglage principal conventionnel (moyen de réglage distinct du second moyen de réglage selon le mode de réalisation de l'invention), d'une longueur supplémentaire déterminée, présentant un faible écart fixe avec la longueur initialement réglée, afin de permettre de passer facilement, sans habileté ni outil particulier, de l'une à l'autre longueur de bracelet. L'écart entre ces deux longueurs est choisi pour tenir compte des différences de pourtour du poignet suivant la chaleur ambiante et/ou suivant les efforts que le porteur du bracelet fait avec son bras et qui se traduisent par un gonflement du poignet. Grâce à un tel dispositif de réglage, il est possible de passer facilement de l'une à l'autre des longueurs déterminées, suivant que le bracelet serre le poignet ou au contraire ne tient pas suffisamment autour du poignet, sans modifier le réglage initial principal de la longueur du bracelet (par le premier moyen de réglage distinct). Ceci est important, en particulier mais pas exclusivement, pour un bracelet de montre.The invention is based on a device for adjusting the length of a bracelet. This adjustment device is intended to allow the user to have, for each initial length of the bracelet set by a first conventional main adjustment means (adjustment means separate from the second adjustment means according to the embodiment of the invention ), a determined additional length, having a small fixed gap with the length initially set, to allow to pass easily, without skill or special tool, from one to the other strap length. The difference between these two lengths is chosen to take into account the differences in the circumference of the wrist according to the ambient heat and / or the efforts that the wearer of the bracelet makes with his arm and which result in swelling of the wrist. With such an adjustment device, it is possible to easily move from one to the other determined lengths, depending on whether the bracelet tightens the wrist or on the contrary does not fit sufficiently around the wrist, without changing the initial initial setting the length of the bracelet (by the first distinct adjustment means). This is important, particularly but not exclusively, for a watch bracelet.
Avantageusement, le dispositif de réglage selon le mode de réalisation de l'invention est associé à un fermoir à lames déployantes, à deux ou trois lames déployantes. De plus, avantageusement, il est compatible avec une structure de bracelet complexe, par exemple un bracelet formé par un ensemble de maillons reliés entre eux par des axes transversaux, le nombre de maillons étant choisi pour définir un réglage initial correspondant sensiblement au pourtour du poignet de l'utilisateur. Chaque maillon peut comprendre plusieurs mailles, juxtaposées dans une direction transversale, comprenant par exemple une ou plusieurs maille(s) de centre insérée(s) entre des mailles de bord. Un tel ensemble est par exemple représenté sur la
Un mode de réalisation particulier va maintenant être décrit de manière détaillée à titre non limitatif, notamment en référence avec les
Le dispositif de réglage selon ce mode de réalisation est agencé à l'extrémité d'un brin de bracelet, au niveau d'un fermoir dont seul un couvercle 2 est représenté en tireté sur les
Comme cela apparaît sur les figures, le bracelet est composé d'une succession de paires de maillons 10, 11, comprenant chacun respectivement trois mailles 10a, 10b, 10c et deux mailles 11 a, 11 b. Le premier maillon 10 comprend donc trois mailles, dont deux mailles de bord 10b, 10c s'étendant sur les côtés du bracelet, et une maille de centre 10a. Ces trois mailles sont reliées entre elles par au moins un axe transversal 12 traversant des ouvertures traversantes de ces trois mailles. Ces dernières présentent la même longueur et s'étendent parallèlement dans la direction longitudinale, et leurs deux extrémités longitudinales sont positionnées au même niveau. La largeur L10a de la maille de centre 10a est inférieure ou égale à celle L10b, L10c des deux mailles de bord 10b, 10c, de même longueur dans ce mode de réalisation. Un tel premier maillon 10 est associé, sur chacune de ses deux extrémités longitudinales, à un second maillon 11 constitué de deux mailles 11 a, 11 b. Ces deux mailles 11 a, 11 b constituent des mailles de centre. Elles sont positionnées pour venir s'intercaler entre respectivement les mailles 10a, 10b et 10a, 10c du premier maillon 10. Leur extrémité est montée sur un axe 12 reliant les trois mailles 10a, 10b, 10c du premier maillon 10, de manière articulée, laissant libres en rotation relative les deux maillons 10, 11. Les deux mailles 11 a, 11 b du second maillon 11 sont sensiblement identiques et présentent la même longueur et la même forme que les trois mailles 10a, 10b, 10c du premier maillon 10 et leur extrémité intégrée entre deux mailles du premier maillon se trouve sensiblement au milieu de la longueur des trois mailles 10a, 10b, 10c. Leur largeur est sensiblement la même, et sensiblement aussi la même que celle de la maille de centre 10a du premier maillon 10. Ces largeurs des mailles sont telles que les bords latéraux de toutes les mailles juxtaposées, qui se présentent sous forme de flancs dans un plan longitudinal vertical, viennent sensiblement en contact, ne laissant paraître aucun vide. Les trois mailles 10a, 10b, 10c de deux premiers maillons 10 successifs viennent en contact sur leurs extrémités longitudinales. Il en est de même de deux seconds maillons 11 successifs: de même, les deux mailles 11 a, 11 b de deux seconds maillons 11 successifs viennent en contact sur leurs extrémités longitudinales. Toutes les mailles présentent une surface supérieure visible arrondie et des flancs latéraux plans, orientés selon une direction longitudinale et verticale.As shown in the figures, the bracelet is composed of a succession of pairs of
Le brin de bracelet obtenu est ainsi composé de cinq mailles juxtaposées de manière parallèle sur la largeur du bracelet, obtenues par une succession de maillons intercalés de respectivement trois mailles et deux mailles, les deux mailles étant décalées longitudinalement par rapport auxdites trois mailles voisines. Il ressort de cette construction une apparence esthétique très harmonieuse, notamment du fait d'un nombre important de mailles articulées entre elles, et notamment de mailles de centre de faible largeur. De plus, ce grand nombre de mailles permet d'atteindre un grand confort de porter de ce bracelet, puisque les mailles articulées épousent au mieux le contour du poignet. Ce confort diminue si la dimension des mailles augmente et/ou si le nombre de mailles est réduit.The bracelet strand obtained is thus composed of five meshes juxtaposed parallel to the width of the bracelet, obtained by a succession of interposed links of respectively three meshes and two meshes, the two meshes being offset longitudinally with respect to said three adjacent meshes. This construction results in a very harmonious aesthetic appearance, in particular because of a large number of meshes articulated between them, and in particular center meshes of small width. In addition, this large number of stitches makes it possible to achieve a great wearing comfort of this bracelet, since the articulated stitches marry at best the contour of the wrist. This comfort decreases if the mesh size increases and / or the number of meshes is reduced.
L'extrémité d'un tel bracelet est reliée à un dispositif de réglage, en particulier un réglage de confort, de sa longueur, conformé pour permettre une légère adaptation de la longueur du bracelet, en complément d'un réglage initial conventionnel, comme expliqué précédemment.The end of such a bracelet is connected to a regulating device, in particular a comfort adjustment, of its length, shaped to allow a slight adjustment of the length of the bracelet, in addition to a conventional initial setting, as explained above.
Ce dispositif de réglage selon le mode de réalisation de l'invention, plus particulièrement visible sur les
Comme plus particulièrement représenté sur la
Le maillon d'extrémité 8 présente un second alésage, au niveau d'une seconde extrémité 8j, prévu pour recevoir le second axe 9, particulièrement visible sur la
Enfin, les deux extrémités 8i, 8j du maillon d'extrémité 8, portant respectivement les deux alésages pour recevoir les deux axes 7, 9, sont reliées par une découpe transversale 8c de forme sensiblement demi-cylindrique. Elle comprend de plus une paroi 8d en forme de S, sensiblement en position centrale de cette découpe 8c, dont la dimension est prévue pour être légèrement inférieure à la barrette formant le premier axe 5, de sorte à pouvoir se clipper élastiquement sur cet axe 5, dans une configuration courte du dispositif de réglage. Cette paroi 8d forme ainsi un rétrécissement à l'entrée du logement formé par la découpe transversale 8c, dont la dimension est calculée pour être légèrement inférieure à la dimension correspondante de la partie de l'axe 5 qui doit s'engager dans le logement. Cette paroi 8d sert donc de moyen d'accrochage pour l'axe 5 lorsque celui-ci est engagé élastiquement dans ce logement en configuration courte du dispositif de réglage. Cette découpe transversale 8c vient de plus tronquer la seconde extrémité 8j du maillon d'extrémité, dont les deux parties 8a, 8b latérales autour de la découpe 8e reprennent la forme de demi mailles 11 a, 11 b, coupées en leur centre par un plan médian transversal.Finally, the two ends 8i, 8j of the
En remarque, le maillon d'extrémité 8 se présente en une seule pièce. Ses deux extrémités 8i, 8j sont liées entre elles de manière solidaire, sans mouvement respectif. Le maillon d'extrémité 8 forme donc une pièce monolithique. Il se présente sous une forme monobloc.Note, the

Le dispositif de réglage selon l'invention permet de procéder à un réglage de longueur entre deux longueurs de bracelet déterminées. Le passage d'une position à l'autre n'est obtenu que volontairement, par une manipulation simple, ne demandant pas d'habileté particulière de l'utilisateur. En effet, le changement de configuration du dispositif de réglage est obtenu par une simple force exercée volontairement sur l'extrémité de son bracelet, dans la direction souhaitée d'actionnement, par l'utilisateur. Une fois positionnée dans une configuration choisie, il n'y a pas de risque que la longueur change involontairement. Cette longueur réglée est maintenue aussi longtemps que l'utilisateur n'en a pas décidé autrement. Le fermoir peut être ouvert et refermé sans que le réglage ne soit modifié. On peut aussi remarquer que dans l'une ou l'autre des configurations de longueur, la hauteur du fermoir reste inchangée, de sorte que ce dispositif ne nuit pas à l'aspect esthétique du bracelet.The adjustment device according to the invention makes it possible to adjust the length between two determined bracelet lengths. The transition from one position to another is obtained only voluntarily, by simple manipulation, not requiring any particular skill of the user. Indeed, the configuration of the adjustment device is obtained by a simple force exerted voluntarily on the end of his bracelet, in the desired direction of actuation, by the user. Once positioned in a chosen configuration, there is no risk that the length changes unintentionally. This set length is maintained as long as the user has not decided otherwise. The clasp can be opened and closed without the setting being changed. It may also be noted that in one or other of the length configurations, the height of the clasp remains unchanged, so that this device does not detract from the aesthetic appearance of the bracelet.

La solution selon le mode de réalisation est particulièrement adaptée à un bracelet comprenant des maillons articulés, et plus particulièrement des maillons comprenant plusieurs mailles, dont des mailles de centre et de bord, comme explicité précédemment. Dans une telle structure, la largeur de tout ou partie des mailles de centre 10a, 11 a, 11 b est inférieure ou égale à celle d'une maille de bord 10b, 10c. Préférentiellement encore, la maille de centre 10a d'un maillon présente une largeur L10a inférieure ou égale à la largeur L10b de la première maille de bord 10b et/ou inférieure ou égale à la largeur L10c de la seconde maille de bord 10c (
La largeur L8e de la découpe 8e correspond sensiblement à la largeur L10a d'une maille de centre 10a d'un maillon du bracelet, comme explicité précédemment, et peut donc de même être inférieure ou égale à la largeur d'au moins une maille de bord L10b, L10c, et éventuellement respecter la ou les conditions suivantes: 1≤L10b/L8e<1.5, voire <1.3, voire <1.2 et/ou 1≤L10c/L10a<1.5, voire <1.3, voire <1.2.The width L8e of the
D'autre part, comme la largeur L8a, L8b des deux parties 8a, 8b latérales du maillon d'extrémité 8 correspond à celle des mailles de centre 11 a, 11 b, cette largeur est avantageusement sensiblement égale à la largeur de la maille de centre L10a (soit aussi L8e). Enfin, la largeur L10b, L10c des mailles de bord 10b, 10c, qui sont disposées contre les flancs extérieurs du maillon d'extrémité 8 dans la continuité des deux mailles de bord 6b, 6c du maillon de réglage 6, correspond sensiblement à la largeur de ces deux mailles de bord 6b, 6c du maillon de réglage 6.On the other hand, since the width L8a, L8b of the two
Rien n'empêche cependant d'utiliser le dispositif de réglage décrit précédemment avec d'autres types de bracelets, comprenant un nombre différents de mailles, voire en cuir ou en plastique par exemple. De même, il peut s'agir aussi bien d'un bracelet de montre que de n'importe quel autre bracelet, pour tout objet à fixer sur un poignet ou toute autre partie du corps. Cet objet peut être un accessoire de plongée sous-marine tel un profondimètre ou un ordinateur de plongée sous-marine par exemple, ou encore un composant de joaillerie.However, nothing prevents the use of the adjustment device described above with other types of bracelets, comprising a different number of meshes, or even leather or plastic for example. Likewise, it can be a watch strap as well as any other bracelet, for any object to be fixed on a wrist or any other part of the body. This object can be a scuba diving accessory such as a depth gauge or a scuba diving computer, for example, or a jewelery component.
D'autre part, le dispositif de réglage s'adapte particulièrement à un fermoir du type à lames déployantes ou d'un type comparable, de façon générale à tout bracelet formant avec son fermoir un lien sans fin. Il est par exemple adaptable sur un fermoir double déployant, comprenant une lame centrale aux extrémités de laquelle sont respectivement montées mobile en pivotement une première lame mobile repliable et une seconde lame mobile repliable.On the other hand, the adjustment device is particularly suitable for a clasp type folding blades or a comparable type, generally any bracelet forming with its clasp an endless link. It is for example adaptable to a double folding clasp, comprising a central blade at the ends of which are respectively mounted to pivotally movable a first folding mobile blade and a second folding mobile blade.
Plus généralement, le dispositif de réglage de la longueur du bracelet, tel que décrit précédemment, est avantageusement associé à toute lame déployante d'un fermoir. Avantageusement, le maillon de réglage et éventuellement au moins une partie du maillon d'extrémité se trouve disposé sous un couvercle formé par le fermoir, ce mécanisme restant ainsi caché. La partie visible garantit l'intégrité esthétique du bracelet, dans les deux configurations du dispositif de réglage, comme explicité précédemment.More generally, the device for adjusting the length of the bracelet, as described above, is advantageously associated with any folding blade of a clasp. Advantageously, the adjusting link and possibly at least a portion of the end link is disposed under a lid formed by the clasp, this mechanism thus remaining hidden. The visible part guarantees the aesthetic integrity of the bracelet, in both configurations of the adjustment device, as explained above.
L'invention porte aussi sur un bracelet et/ou un fermoir, qui intègre(nt) au moins un dispositif de réglage de la longueur du bracelet. Un dispositif de réglage de la longueur du bracelet peut être disposé sur chaque extrémité des brins de bracelet, ou sur une seule extrémité.The invention also relates to a bracelet and / or a clasp, which integrates (s) at least one device for adjusting the length of the bracelet. A device for adjusting the length of the bracelet may be arranged on each end of the bracelet strands, or on one end only.
Le dispositif de réglage selon l'invention peut subir des modifications sans sortir du cadre de la présente invention. Notamment, le maillon de réglage peut présenter d'autres formes. Il comprend un élément qui coopère avec le maillon d'extrémité en configuration courte pour permettre l'accrochage respectif des deux maillons. De plus, le maillon d'extrémité 8 peut de même présenter d'autres formes. Notamment, sa seconde extrémité 8j s'adapte à l'architecture du bracelet, et peut comprendre plusieurs découpes 8e parallèles, et tout autre nombre de parties imitant une maille de bracelet.The adjustment device according to the invention may be modified without departing from the scope of the present invention. In particular, the adjustment link may have other forms. It comprises an element that cooperates with the end link in short configuration to allow the respective attachment of the two links.
