Abstract

The present invention relates to an extensible device (1) for a watch strap (40) of predefined length, in particular for a diving watch strap. The extensible device can adopt two configurations, one short and one long, by a relative movement of two extreme parts (2, 3) between a mutually close position and a mutually distant position. Locking means (22, 24, 27, 32) are provided to keep the device in its short configuration, and the latter also has at least one control member (11). The latter can be used to operate the locking means in order to release the extreme parts from each other and allow the short configuration to be changed to the long configuration. The control member (11) is designed to be movable between two positions, a first position in which it is close to the extreme parts, and a second pulled position, in which it is remote from the extreme parts. The first position corresponds to a locked condition of the locking means, while the second position corresponds to their unlocked condition, which ensures a high degree of safety of the locking means and limits the risk of accidental manipulation of the extensible device.

DISPOSITIF EXTENSIBLE POUR BRACELET DE MONTRE Domaine techniqueEXTENSIBLE DEVICE FOR WATCH BRACELET Technical Area
[0001] La présente invention concerne un dispositif extensible pour bracelet de montre du type fermé et à longueur prédéfinie. Plus précisément, le présent dispositif extensible est destiné à être intégré dans un tel bracelet pour permettre d'en augmenter la longueur, notamment pour permettre la mise en place d'un appareil portable au poignet, tel une montre, pardessus une combinaison de plongée. Etat de la techniqueThe present invention relates to an extensible device for a watch strap of the closed type and predefined length. More specifically, the present extensible device is intended to be integrated in such a bracelet to allow to increase the length, in particular to allow the establishment of a portable device to the wrist, such as a watch, over a diving suit. State of the art
[0002] Des dispositifs extensibles de ce type sont connus de l'état de la technique. [0003] A titre d'exemple, la demande de brevet EP 0 819 391 A1 , déposée au nom des Montres Rolex S.A., décrit un dispositif de réglage de la longueur d'un bracelet métallique muni d'un fermoir à lames déployantes. Le fermoir comporte un capot dans lequel est logé le mécanisme à lames déployantes lorsque le fermoir est fermé. Une première extrémité du bracelet est solidaire du capot tandis que la seconde extrémité du bracelet est solidaire du dispositif de réglage, lui-même solidaire du capot. [0004] Le dispositif de réglage comprend deux maillons adjacents reliés entre eux en pivotement pour permettre leur mouvement relatif entre deux configurations, une courte et une longue. Dans la configuration courte, l'un des maillons est logé dans un espace adapté de l'autre maillon, des surfaces respectives de l'un et l'autre maillons étant disposées en appui l'une contre l'autre pour remplir une fonction de verrouillage de la configuration courte.Extensible devices of this type are known from the state of the art. By way of example, patent application EP 0 819 391 A1, filed in the name of the Rolex S.A. Watches, describes a device for adjusting the length of a metal bracelet provided with a clasp with folding blades. The clasp has a hood in which is housed the folding blade mechanism when the clasp is closed. A first end of the bracelet is integral with the hood while the second end of the bracelet is integral with the adjustment device, itself secured to the hood. The adjustment device comprises two adjacent links pivotally interconnected to allow their relative movement between two configurations, a short and a long. In the short configuration, one of the links is housed in a space adapted to the other link, the respective surfaces of the one and the other links being arranged in support against each other to fulfill a function of lock the short configuration.
[0005] Lorsque les lames déployantes du fermoir sont repliées sous le capot, elles recouvrent le dispositif de réglage pour le dissimuler. En conséquence, pour passer de la configuration courte à la configuration longue, et inversement, le fermoir doit nécessairement être ouvert pour permettre les mouvements des deux maillons de réglage.When the folding clasp of the blades are folded under the hood, they cover the adjustment device to hide it. Consequently, to pass from the short configuration to the long configuration, and vice versa, the clasp must necessarily be open to allow the movements of the two adjustment links.
[0006] Par ailleurs, une simple traction sur le bracelet suffit à déverrouiller le dispositif de réglage lorsque le fermoir est ouvert. Ceci peut conduire à des ouvertures intempestives du dispositif de réglage lorsque le porteur de la montre ouvre le fermoir pour enlever ou mettre sa montre. [0007] Par ailleurs, ce type de structure ne convient pas à toutes les formes de bracelet métallique. En particulier, certains bracelets métalliques présentent des fermoirs ne comportant pas de capot et ne sont donc pas adaptés à la mise en œuvre du dispositif de réglage décrit ci-dessus, dans la mesure où ce dernier ne pourrait pas être dissimulé sous le bracelet, étant donnée son épaisseur. Divulgation de l'invention [0008] La présente invention a notamment pour but de pallier l'inconvénient de l'art antérieur susmentionné en proposant un dispositif extensible pour bracelet de montre présentant des moyens spécifiques pour garantir sa stabilité lorsqu'il est dans sa configuration courte.Moreover, a simple pull on the bracelet is enough to unlock the adjustment device when the clasp is open. This can lead to inadvertent opening of the adjustment device when the wearer of the watch opens the clasp to remove or put his watch. Moreover, this type of structure is not suitable for all forms of metal bracelet. In particular, some metal wristbands have clasps that do not have a hood and are therefore not suitable for the implementation of the adjustment device described above, since the latter could not be hidden under the wristband, being given its thickness. Disclosure of the invention The present invention is intended in particular to overcome the disadvantage of the above-mentioned prior art by providing an extensible device for a watch strap having specific means to guarantee its stability when in its configuration. short.
[0009] Un autre but du dispositif extensible selon la présente invention est de proposer une structure qui peut être mise en œuvre sur tout type de bracelet sans nuire à l'aspect de ce dernier.Another object of the extensible device according to the present invention is to provide a structure that can be implemented on any type of bracelet without harming the appearance of the latter.
[0010] A cet effet, l'invention a pour objet un dispositif extensible pour bracelet de montre comprenant un premier et un deuxième maillons, adjacents, comportant respectivement des première et deuxième pièces extrémales. Ces dernières sont destinées à être rendues solidaires respectivement d'une première et d'une deuxième extrémités du bracelet, le dispositif étant agencé de manière à pouvoir présenter au moins deux configurations, une courte et une longue. Ce dispositif comporte en outre des moyens de verrouillage présentant au moins un état ouvert et un état fermé dans lequel la stabilité de ladite configuration courte est assurée.For this purpose, the invention relates to an extensible device for a watch strap comprising a first and a second link, adjacent, respectively comprising first and second extremal parts. These are intended to be secured respectively to a first and a second ends of the bracelet, the device being arranged to be able to have at least two configurations, a short and a long. This device further comprises locking means having at least one open state and a closed state in which the stability of said short configuration is ensured.
[0011] Plus particulièrement, le dispositif extensible selon la présente invention est caractérisé par le fait qu'il comprend au moins un organe de commande des moyens de verrouillage susceptible d'être déplacé entre deux positions, suivant une direction sensiblement parallèle audit plan général. Une première position, rapprochée par rapport aux maillons, définit l'état fermé des moyens de verrouillage, tandis que la deuxième position, éloignée par rapport aux maillons, définit l'état ouvert des moyens de verrouillage. [0012] De manière préférée, le dispositif comprend des moyens élastiques agencés pour exercer une force de rappel sur l'organe de commande tendant à maintenir ce dernier dans sa position rapprochée.More particularly, the extensible device according to the present invention is characterized in that it comprises at least one control member locking means capable of being moved between two positions in a direction substantially parallel to said general plane. A first position, close to the links, defines the closed state of the locking means, while the second position, remote from the links, defines the open state of the locking means. Preferably, the device comprises elastic means arranged to exert a restoring force on the control member tending to maintain the latter in its close position.
[0013] Grâce à ses caractéristiques particulières, le dispositif extensible selon l'invention présente une grande fiabilité de manipulation, en prévenant notamment des ouvertures intempestives qui entraîneraient un allongement du bracelet non souhaité.Thanks to its particular characteristics, the extensible device according to the invention has a high handling reliability, particularly preventing untimely openings that would cause an undesirable extension of the bracelet.
[0014] Suivant des modes de réalisations préférés, les moyens de verrouillage comprennent au moins un ergot monté en translation dans une première pièce extrémale du dispositif et destiné à coopérer avec un trou adapté ménagé dans la deuxième pièce extrémale, lorsque le dispositif est dans sa configuration courte. L'ergot est monté solidaire d'un organe de commande agencé sur un côté du dispositif, en étant sensiblement perpendiculaire à la direction du bracelet dans lequel le dispositif est intégré. Dans une variante avantageuse de la présente invention, deux ergots similaires associés à deux organes de commande correspondants sont agencés de part et d'autre du dispositif extensible pour en renforcer la fiabilité de fonctionnement.According to preferred embodiments, the locking means comprise at least one lug mounted in translation in a first end piece of the device and intended to cooperate with a fitted hole formed in the second end piece, when the device is in its short configuration. The lug is mounted integral with a control member arranged on one side of the device, being substantially perpendicular to the direction of the bracelet in which the device is integrated. In an advantageous variant of the present invention, two similar pins associated with two corresponding control members are arranged on either side of the extensible device to enhance the reliability of operation.
[0015] De manière générale, le dispositif extensible peut présenter une structure similaire à celle d'un fermoir à lames déployantes pour la partie structurelle relative à la variation de sa longueur.In general, the extensible device may have a structure similar to that of a clasp with folding blades for the structural part relating to the variation of its length.

Une bague 28 est logée, dans une position fixe, à l'entrée du trou 25, du côté de l'organe de commande, pour y définir une seconde surface d'appui du ressort 27. Du fait de cette structure, le ressort agit simultanément sur le disque 26 et la bague 28 pour maintenir l'organe de commande 1 1 et la tige 22 en position enfoncée, représentée sur la figure 2. [0031] La seconde pièce extrémale 3 comporte deux trous borgnes 32 ménagés dans ses faces latérales de manière qu'ils sont alignés l'un avec l'autre et tous deux par rapport aux tiges 22 lorsque le dispositif extensible est dans sa configuration courte.The locking means of the extensible device 1 are visible in transparency in Figure 2, the device having two control members 11, arranged on either side of the first end piece 2. Each control member 11, arranged on the outer side of a respective lateral element 21, has the shape of a ring comprising a threaded hole in its face facing the corresponding lateral element. A rod 22 is engaged in a hole 25 adapted from each of the lateral elements 21. This has a first threaded end 23, screwed into the corresponding control member, and a second end 24 which opens out from the opposite side of the corresponding side element to form a lug. In addition, the locking means comprise a disc 26, rigidly attached to the rod 22, to define a first bearing surface of a coil spring 27. A ring 28 is housed, in a fixed position, to the the entrance of the hole 25, on the side of the control member, to define a second bearing surface of the spring 27. Due to this structure, the spring acts simultaneously on the disc 26 and the ring 28 to maintain the control member 1 1 and the rod 22 in the depressed position, shown in Figure 2. The second end piece 3 has two blind holes 32 formed in its side faces so that they are aligned with each other and both with respect to the rods 22 when the extensible device is in its short configuration.
[0032] Ainsi, la coopération des deux tiges 22 avec les trous 32, sous l'effet des deux ressorts 27, garantit le verrouillage de la seconde pièce extrémale 3 avec la première pièce extrémale 2 dans la configuration courte du dispositif extensible 1. Les deux pièces extrémales sont donc solidaires par le biais d'une liaison de type pivot.Thus, the cooperation of the two rods 22 with the holes 32, under the effect of the two springs 27, ensures the locking of the second end piece 3 with the first end piece 2 in the short configuration of the extensible device 1. The two extremal parts are thus integral through a pivot type connection.
[0033] Par ailleurs, la seconde pièce extrémale 3 présente un bourrelet 33 (visible sur la figure 1), en saillie sur sa face inférieure et, comportant un trou (visible en transparence sur la figure 3) pour loger la barrette 6 permettant de la connecter à la seconde lame 9. De manière préférée, les dimensions du bourrelet 33 sont telles qu'il présente une forme sensiblement complémentaire à celle de l'évidement 10 de la patte recourbée 4 de la première pièce extrémale 2.Furthermore, the second end piece 3 has a bead 33 (visible in Figure 1), projecting on its underside and, having a hole (visible in Figure 3) to accommodate the bar 6 allowing connect it to the second blade 9. Preferably, the dimensions of the bead 33 are such that it has a shape substantially complementary to that of the recess 10 of the bent tab 4 of the first end piece 2.
[0034] Les dimensions des différents éléments constituant les moyens de verrouillage sont préférablement adaptées pour que les ergots des extrémités libres 24 des tiges 22 s'escamotent complètement à l'intérieur des éléments latéraux 21 de la première pièce extrémale 2, libérant ainsi la seconde pièce extrémale 3, en réponse à une traction exercée par un utilisateur sur les deux organes de commande 1 1 en les écartant simultanément des pièces extrémales.The dimensions of the various elements constituting the locking means are preferably adapted so that the lugs of the free ends 24 of the rods 22 retract completely inside the lateral elements 21 of the first end piece 2, thus releasing the second extremal piece 3, in response to a pull exerted by a user on the two control members 1 1 by simultaneously spacing the extremal parts.
[0035] Cette opération de déverrouillage permet de faire passer le dispositif extensible selon la présente invention de sa configuration courte à une configuration longue, représentée sur la figure 3.This unlocking operation makes it possible to pass the extensible device according to the present invention from its short configuration to a long configuration, represented in FIG. 3.
[0036] Le fait d'escamoter les ergots des moyens de verrouillage permet de libérer la seconde pièce extrémale 3 par rapport à la première pièce extrémale 2. Les lames 8 et 9 sont alors libres de pivoter l'une par rapport à l'autre, autour de la barrette 6 assurant leur liaison. La longueur maximale du dispositif extensible 1 est obtenue lorsque les deux lames 8 et 9 sont disposées sensiblement dans le prolongement l'une de l'autre. [0037] Pour le passage de la configuration longue à la configuration courte, les lames 8 et 9 doivent être ramenées l'une sur l'autre par un mouvement de pivotement inverse autour de la barrette 6 les reliant. Ce mouvement est réalisé de manière que le bourrelet 33 de la seconde pièce extrémale 3 est inséré dans l'évidement 10 de la patte recourbée 4. [0038] Dans un même temps, les tiges 22 sont repoussées à l'intérieur des éléments latéraux 21 sous la pression de l'élément central 30. A cet effet, les extrémités libres 24 des tiges présentent chacune un chanfrein (non visible) de pente droite ou incurvée. En outre, on peut prévoir que l'élément central 30 comporte des gorges (non représentées), dans ses faces latérales, en forme de rampes, pour permettre l'exercice d'une force axiale sur les extrémités 24 des tiges 22 lors de l'insertion de l'élément central 30 entre les éléments latéraux 21. On comprend bien que de telles rampes devraient préférablement s'étendre à partir de la face inférieure de l'élément central 30 pour déboucher dans les trous 32. De plus, la profondeur de chacune des rampes, au niveau de la surface inférieure de la seconde pièce extrémale, coïncide idéalement avec la position des extrémités 24 lorsque les ressorts 27 sont étendus au maximum. [0039] Lorsque la seconde pièce extrémale 3 est enfoncée en direction de l'évidement 10 jusqu'à ce que les trous 32 soient positionnés sensiblement dans l'alignement des tiges 22, ces dernières sont repoussées vers l'intérieur des trous 32 sous l'effet de la force exercée par les ressorts 27 sur les disques 26. Le fond de chacun des trous 25 des éléments latérauxThe fact of retracting the lugs of the locking means makes it possible to release the second extremal piece 3 with respect to the first extremal piece 2. The blades 8 and 9 are then free to pivot relative to each other. to the other, around the bar 6 ensuring their connection. The maximum length of the extensible device 1 is obtained when the two blades 8 and 9 are arranged substantially in the extension of one another. For the passage from the long configuration to the short configuration, the blades 8 and 9 must be brought back to one another by a reverse pivoting movement around the bar 6 connecting them. This movement is carried out in such a way that the bead 33 of the second end piece 3 is inserted into the recess 10 of the curved lug 4. At the same time, the rods 22 are pushed back inside the lateral elements 21 under the pressure of the central element 30. For this purpose, the free ends 24 of the rods each have a chamfer (not visible) of straight or curved slope. In addition, it can be provided that the central element 30 has grooves (not shown), in its lateral faces, in the form of ramps, to allow the exercise of an axial force on the ends 24 of the rods 22 during operation. insertion of the central element 30 between the lateral elements 21. It is well understood that such ramps should preferably extend from the underside of the central element 30 to open into the holes 32. In addition, the depth of each of the ramps, at the bottom surface of the second end piece, coincides ideally with the position of the ends 24 when the springs 27 are extended to the maximum. When the second end piece 3 is pressed towards the recess 10 until the holes 32 are positioned substantially in alignment with the rods 22, the latter are pushed towards the inside of the holes 32 under the effect of the force exerted by the springs 27 on the discs 26. The bottom of each of the holes 25 of the lateral elements
21 définit une butée pour le déplacement du disque 26 correspondant, lors de la translation des tiges 22 dans les trous 32 de l'élément central 30.21 defines a stop for the displacement of the corresponding disk 26, during the translation of the rods 22 in the holes 32 of the central element 30.
[0040] On constate, notamment au regard de l'illustration de la figure 1, que la coopération du bourrelet 33 avec l'évidement 10 contribue à améliorer la stabilité en traction du dispositif extensible dans sa direction longitudinale en plus de définir une butée lors du passage de la configuration longue à la position courte. [0041] L'agencement de l'ensemble des éléments qui viennent d'être décrits contribue ainsi à verrouiller ensemble les deux pièces extrémales 2 et 3. [0042] Par ailleurs, les pièces extrémales disposent de moyens conventionnels pour permettre leur connexion à un bracelet de type courant. On constate notamment, sur les figures 1 à 3, la présence de trous 29, 34 destinés à loger des barrettes pour connecter des maillons ou brins de bracelet de manière connue. [0043] La figure 4 représente une vue de côté du dispositif extensible 1 précédemment décrit lorsqu'il est assemblé avec un bracelet particulier, à titre d'exemple.It is noted, in particular with regard to the illustration of Figure 1, that the cooperation of the bead 33 with the recess 10 contributes to improving the tensile stability of the extensible device in its longitudinal direction in addition to defining a stop when from the long configuration to the short position. The arrangement of all the elements that have just been described thus contributes to locking together the two extremal parts 2 and 3. Moreover, the extremal parts have conventional means to allow their connection to a device. current type bracelet. In particular, FIGS. 1 to 3 show the presence of holes 29, 34 intended to house bars for connecting links or bracelet strands in a known manner. Figure 4 shows a side view of the extensible device 1 previously described when assembled with a particular bracelet, as an example.
[0044] Le bracelet 40 représenté est du type à maillons métalliques comportant deux brins 41 et 42. Chaque brin comprend un maillon d'extrémité 43 destiné à être relié à une boîte de montre (non représentée). [0045] Par ailleurs, les deux brins 41 et 42 sont connectés l'un à l'autre au moyen d'un fermoir à lames déployantes 44 de type conventionnel. L'homme du métier pourra notamment mettre en œuvre un fermoir tel que celui décrit dans la demande de brevet WO 2004/086895 A1 , déposée au nom de laThe bracelet 40 shown is of the metal link type comprising two strands 41 and 42. Each strand comprises an end link 43 intended to be connected to a watch case (not shown). Moreover, the two strands 41 and 42 are connected to each other by means of a clasp folding blades 44 of conventional type. Those skilled in the art may in particular implement a clasp such as that described in patent application WO 2004/086895 A1, filed in the name of the
Demanderesse.Applicant.
[0046] Dans un mode de réalisation préféré de la présente invention, tel qu'apparent de la figure 4, le dispositif extensible 1 est intégré au braceletIn a preferred embodiment of the present invention, as shown in Figure 4, the extensible device 1 is integrated into the bracelet.
40 à la manière d'un maillon ordinaire, entre le fermoir 44 et un brin 42 du bracelet. [0047] Le bracelet 40 présente une longueur prédéfinie, ajustée à la taille du poignet de son porteur, le fermoir à lames déployantes permettant à ce dernier d'enfiler ou de retirer la montre de son poignet, l'ouverture du fermoir entraînant l'agrandissement de la longueur du bracelet à cet effet. [0048] L'actionnement du dispositif extensible 1 selon la présente invention permet d'augmenter la longueur du bracelet 40, de manière qu'il présente préférablement une longueur intermédiaire entre celles correspondant, d'une part, à la configuration fermée du fermoir et, d'autre part, à la configuration ouverte du fermoir. Grâce à ces caractéristiques, une montre munie d'un bracelet tel que celui représenté sur la figure 4 peut avantageusement être portée par-dessus une combinaison de plongée, lorsque le dispositif extensible 1 est dans sa configuration longue.40 in the manner of an ordinary link, between the clasp 44 and a strand 42 of the bracelet. The bracelet 40 has a predefined length, adjusted to the size of the wrist of the wearer, the clasp with folding blades allowing the latter to slip on or remove the watch from his wrist, the opening of the clasp leading the enlargement of the length of the bracelet for this purpose. The actuation of the extensible device 1 according to the present invention makes it possible to increase the length of the bracelet 40, so that it preferably has an intermediate length between those corresponding, on the one hand, to the closed configuration of the clasp and on the other hand, to the open configuration of the clasp. Thanks to these characteristics, a watch provided with a bracelet such as that shown in FIG. advantageously be worn over a diving suit, when the extensible device 1 is in its long configuration.
[0049] On peut noter, comme cela a été mentionné plus haut, que la structure des moyens de verrouillage selon la présente invention garantit un haut niveau de sécurité au porteur. En effet, il ressort de la description qui précède qu'il est nécessaire d'exercer une traction pour neutraliser les moyens de verrouillage selon la présente invention, avant de pouvoir modifier la longueur du dispositif extensible, alors que les moyens de verrouillage généralement mis en œuvre dans le domaine des bracelets nécessitent des mouvements du type par pression.It may be noted, as mentioned above, that the structure of the locking means according to the present invention ensures a high level of security to the wearer. Indeed, it follows from the foregoing description that it is necessary to exert traction to neutralize the locking means according to the present invention, before the length of the extensible device can be modified, while the locking means generally work in the field of bracelets require movements of the type by pressure.
[0050] En outre, la structure du dispositif extensible selon la présente invention assure une grande discrétion dans la mesure où, au lieu d'être dissimulé sous un capot de fermoir comme dans certains dispositifs connus dans l'état de la technique, il présente une forme très proche de celle des maillons ordinaires du bracelet sur lequel il est monté.In addition, the structure of the extensible device according to the present invention ensures great discretion in that, instead of being concealed under a clasp cover as in some devices known in the state of the art, it presents a form very close to that of the ordinary links of the bracelet on which it is mounted.
[0051] Bien sûr, la description qui précède d'un mode de réalisation préféré est présentée à titre illustratif non limitatif et l'homme du métier ne rencontrera pas de difficulté particulière pour mettre en œuvre un grand nombre de variantes de réalisation sans sortir du cadre de la présente invention. [0052] En particulier, on peut noter qu'il est possible de prévoir un seul organe de commande des moyens de verrouillage sans nuire aux qualités du dispositif susmentionnées. De même, la structure des moyens de verrouillage est décrite à titre non limitatif. On peut par exemple prévoir de manière alternative, sans sortir du cadre de la présente invention, que la couronne 11 et la tige 22 sont réalisées d'une seule pièce. On peut également remplacer le système ergot - trou borgne par un système de plaquette comprenant une fenêtre coopérant avec un crochet de forme adapté. Dans ce cas, une traction exercée sur un organe de commande entraîne un mouvement relatif de translation entre la fenêtre et le crochet pour les aligner et permettre à ce dernier d'être extrait de la plaquette.Of course, the foregoing description of a preferred embodiment is presented by way of nonlimiting illustration and the person skilled in the art will not encounter any particular difficulty in implementing a large number of variant embodiments without departing from the of the present invention. In particular, it can be noted that it is possible to provide a single control member of the locking means without harming the qualities of the aforementioned device. Similarly, the structure of the locking means is described in a non-limiting manner. It may for example be provided alternatively, without departing from the scope of the present invention, that the ring 11 and the rod 22 are made in one piece. It is also possible to replace the pin-blind hole system with a plate system comprising a window cooperating with a hook of suitable shape. In this case, traction exerted on a control member causes a relative movement of translation between the window and the hook to align them and allow the latter to be extracted from the wafer.
[0053] Par ailleurs, l'homme du métier ne rencontrera pas de difficulté particulière pour réaliser les pièces extrémales 2 et 3 selon toute autre forme adaptée à la mise en œuvre de l'invention, notamment en fonction de l'apparence du bracelet destiné à intégrer le dispositif extensible. On notera également que les applications du dispositif extensible qui vient d'être décrit ne sont pas non plus limitées aux bracelets du type comprenant un fermoir à lames déployantes. Furthermore, the skilled person will not encounter any particular difficulty to produce the extremal parts 2 and 3 in any other suitable form. the implementation of the invention, in particular according to the appearance of the bracelet for integrating the expandable device. It will also be noted that the applications of the extensible device which has just been described are also not limited to bracelets of the type comprising a folding clasp.
