Abstract

An articulated wristlet has a plurality of decorative elements, an equal number of elements articulated by hinges capable of being unhooked and sliding type fittings. Adjacent lateral faces of two juxtaposed decorative elements hold the decorative elements to each other when the wristlet is worn normally. The lateral faces are shaped to permit the releasing of two adjacent decorative elements when the wristlet is folded beyond a predetermined angle, this releasing permitting the removal of one decorative element of the wristlet and then the unhooking of the corresponding linking element. The arrangement permits adjustment in the length of the wristlet without the use of tools.

Description

L'invention est relative à un bracelet articulé comportant une pluralité d'éléments décoratifs disposés côte à côte selon un axe longitudinal, une âme intérieure pliable, des moyens d'assemblage associant chaque élément décoratif à l'âme intérieure et comportant un ensemble du type glissière n'autorisant un déplacement de l'élément décoratif par rapport à ladite âme intérieure que selon une direction longitudinale, ledit ensemble du type glissière comportant l'engagement de coulisseaux portés par ladite âme intérieure pliable dans des coulisses portées par lesdits éléments décoratifs.The invention relates to an articulated bracelet comprising a plurality of decorative elements arranged side by side along a longitudinal axis, a foldable inner core, assembly means associating each decorative element with the inner core and comprising an assembly of the type slide authorizing a movement of the decorative element relative to said inner core only in a longitudinal direction, said assembly of the slide type comprising the engagement of sliders carried by said foldable inner core in slides carried by said decorative elements.

Un bracelet répondant à la définition générique donnée ci-dessus est décrit dans le brevet CH-A 604 594. Chacun des maillons ou éléments décoratifs apparents de ce bracelet comporte des moyens de verrouillage consistant en deux surfaces semi- cylindriques de même rayon et dont l'une est concave et l'autre convexe. Ce bracelet comporte aussi une âme intérieure pliable et un ensemble du type glissière permettant d'associer chaque élément décoratif à l'âme intérieure. L'âme intérieure comprend une série d'éléments de liaison comportant des parties pliées en forme de crochets et des ouvertures correspondantes pour verrouiller deux éléments décoratifs de façon que la partie concave de l'un s'appuie, tout en pouvant pivoter, sur la partie convexe de l'autre.A bracelet meeting the generic definition given above is described in patent CH-A 604 594. Each of the links or visible decorative elements of this bracelet comprises locking means consisting of two semi-cylindrical surfaces of the same radius and of which the 'one is concave and the other convex. This bracelet also has a foldable inner core and a slide-type assembly allowing each decorative element to be associated with the inner core. The inner core comprises a series of connecting elements comprising parts folded in the form of hooks and corresponding openings for locking two decorative elements so that the concave part of one rests, while being able to pivot, on the convex part of the other.

Comme le bracelet de la présente invention qui va être décrit ci-après, le bracelet du brevet cité ci-dessus comporte une âme intérieure qui supporte à elle seule l'effort mécanique de traction qui est exercé sur ledit bracelet. L'âme est habillée en quelque sorte d'éléments décoratifs sur lesquels n'agit aucune contrainte mécanique. Si le bracelet décrit dans la citation est d'un montage simple où les maillons décoratifs ne sont pas liés par des vis ou des goupilles et n'implique donc pas l'utilisation d'outils spéciaux, se pose alors la question de la mise en longueur du bracelet ou de la modification de son aspect esthétique puisque, dans la construction prévue, il n'existe pas de position angulaire où un élément décoratif puisse être libéré de l'âme intérieure pliable. Cela devra se faire à partir d'un élément spécial d'accrochage qui n'est pas décrit et qui comportera nécessairement l'emploi d'outils.Like the bracelet of the present invention which will be described below, the bracelet of the patent cited above has an inner core which alone supports the mechanical tensile force which is exerted on said bracelet. The soul is dressed in a kind of decorative elements on which no mechanical constraint acts. If the bracelet described in the quotation is of a simple assembly where the decorative links are not linked by screws or pins and therefore does not imply the use of special tools, then arises the question of setting length of the bracelet or the modification of its aesthetic appearance since, in the construction provided, there is no angular position where a decorative element can be released from the foldable inner core. This must be done using a special attachment element which is not described and which will necessarily involve the use of tools.

Pour pallier les inconvénients cités et proposer un bracelet dont au moins un maillon peut être changé ou encore ajouté ou enlevé sans l'aide d'outils quelle que soit sa place dans la chaîne le composant, le bracelet selon la présente invention est remarquable, outre les caractéristiques énumérées au premier paragraphe ci-dessus, par le fait que chaque élément décoratif présente une face latérale couvrant au moins partiellement la face latérale d'un élément décoratif voisin pour verrouiller entre eux lesdites éléments quand le bracelet est porté normalement, lesdites faces latérales étant conformées de telle manière qu'elles se découvrent l'une par rapport à l'autre quand le bracelet est plié au-delà d'un angle prédéterminé permettant ainsi le déverrouillage, puis l'extraction de n'importe quel élément décoratif situé à un endroit quelconque le long du bracelet par glissement dudit élément décoratif le long des coulisseaux sur lesquels il est monté.To overcome the aforementioned drawbacks and propose a bracelet of which at least one link can be changed or added or removed without the aid of tools whatever its place in the chain making it up, the bracelet according to the present invention is remarkable, in addition to the characteristics listed in the first paragraph above, in that each decorative element has a lateral face at least partially covering the lateral face of a neighboring decorative element to lock them said elements when the bracelet is worn normally, said lateral faces being shaped in such a way that they are uncovered in relation to each other when the bracelet is folded beyond a predetermined angle thus allowing unlocking, then extraction of any decorative element located at any place along the bracelet by sliding said decorative element along the slides on which it is mounted.

L'invention sera comprise maintenant à la lecture de la description suivante, description illustrée à titre d'exemple par le dessin dans lequel:

  • - la figure 1 a est une vue partielle de dessous du bracelet selon une forme d'exécution préférée de l'invention, vue limitée à deux maillons dudit bracelet,
  • - la figure 1 b est une coupe selon la ligne Ib-Ib de la figure 1 a,
  • - la figure 1c est une vue selon la flèche C de la figure 1 b,
  • - la figure 2 est une vue en coupe d'une partie du bracelet quand celui-ci est porté normalement sur le poignet,
  • - les figures 3a et 3b sont des dessins géométriques illustrant la rotation d'un élément du bracelet par rapport à un élément voisin dans deux conditions de dimensions différentes,
  • - la figure 4 est une vue en perspective du bracelet des figures 1 a et 1 montrant comment on s'y prend pour enlever un maillon du bracelet, et
  • - les figures 5a à 5m montrent schématiquement les opérations à effectuer quand on désire supprimer un maillon du bracelet selon l'invention.
The invention will now be understood on reading the following description, description illustrated by way of example by the drawing in which:
  • FIG. 1 a is a partial view from below of the bracelet according to a preferred embodiment of the invention, a view limited to two links of said bracelet,
  • FIG. 1 b is a section along the line Ib-Ib in FIG. 1 a,
  • FIG. 1c is a view along arrow C in FIG. 1b,
  • FIG. 2 is a sectional view of part of the bracelet when the latter is normally worn on the wrist,
  • FIGS. 3a and 3b are geometric drawings illustrating the rotation of an element of the bracelet with respect to a neighboring element under two conditions of different dimensions,
  • FIG. 4 is a perspective view of the bracelet of FIGS. 1 a and 1 showing how to proceed to remove a link from the bracelet, and
  • - Figures 5a to 5m schematically show the operations to be performed when it is desired to remove a link from the bracelet according to the invention.

Les figures 1a et 1b sont des dessins montrant une vue de dessous et respectivement en coupe du bracelet selon une forme d'exécution préférée de l'invention, bracelet dont seuls deux maillons ont été représentés. La figure 1c est une vue en bout du bracelet selon la flèche C montrée en figure 1b. Le bracelet comporte une pluralité d'éléments décoratifs 1 qui sont disposés côte à côte. Les éléments décoratifs 1 sont disposés transversalement par ra- port à l'axe longitudinal du bracelet. Le bracelet comporte aussi une âme intérieure pliable 15 composée d'éléments de liaison 7 articulés les uns à la suite des autres au moyen de charnières 8 selon un axe d'articulation x. A chaque élément décoratif 1 est associé un élément de liaison 7 grâce à des moyens d'assemblage du type glissière 9 et qui n'autorise, comme cela est bien visible en figure 1a, un déplacement de l'élément décoratif 1 par rapport à l'élément de liaison correspondant 7 que selon une direction longitudinale symbolisée par la flèche 10. Quand le bracelet est porté normalement les faces latérales voisines 5 et 6 des deux éléments décoratifs 1 se trouvent, au moins partiellement, en regard l'une de l'autre et empêchent ainsi ces éléments de s'échapper des éléments de liaison correspondants 7. Ces faces latérales constituent donc des moyens de verrouillage d'un élément décoratif sur l'autre.Figures 1a and 1b are drawings showing a bottom view and respectively in section of the bracelet according to a preferred embodiment of the invention, bracelet of which only two links have been shown. Figure 1c is an end view of the bracelet according to arrow C shown in Figure 1b. The bracelet comprises a plurality of decorative elements 1 which are arranged side by side. The decorative elements 1 are arranged transversely to the longitudinal axis of the bracelet. The bracelet also includes a foldable inner core 15 composed of connecting elements 7 articulated one after the other by means of hinges 8 along an axis of articulation x. Each decorative element 1 is associated with a connecting element 7 by means of assembly of the slide type 9 and which does not allow, as is clearly visible in FIG. 1a, a movement of the decorative element 1 relative to the 'corresponding connecting element 7 that in a longitudinal direction symbolized by the arrow 10. When the bracelet is normally worn the adjacent side faces 5 and 6 of the two decorative elements 1 are, at least partially, facing one of the other and thus prevent these elements from escaping from the corresponding connecting elements 7. These lateral faces therefore constitute means for locking one decorative element on the other.

Plus particulièrement, dans la forme d'exécution présentée au dessin, les éléments décoratifs 1 ont l'allure d'étriers pourvus chacun de deux branches 2 et 3 reliées par une partie pleine 4 qui forme la partie supérieure visible du bracelet. De même, les faces latérales 5 et 6 de chaque élément décoratif comportent une portion cylindrique convexe 5 et une portion cylindrique concave 6 de rayons de courbure r sensiblement identiques. Ainsi quand les éléments décoratifs 1 sont montés sur les éléments de liaison 7, ils peuvent se mouvoir angulairement l'un par rapport à l'autre par glissement réciproque desdites portions cylindriques.More particularly, in the embodiment presented in the drawing, the decorative elements 1 have the appearance of stirrups each provided with two branches 2 and 3 connected by a solid part 4 which forms the visible upper part of the bracelet. Similarly, the side faces 5 and 6 of each decorative element comprise a convex cylindrical portion 5 and a concave cylindrical portion 6 of radii of curvature r substantially identical. Thus when the decorative elements 1 are mounted on the connecting elements 7, they can move angularly one with respect to the other by reciprocal sliding of said cylindrical portions.

Quand le bracelet est porté normalement, c'est-à-dire lorsque son arrondi épouse la courbure du poignet, les portions cylindriques 5 et 6 sont au moins partiellement en regard l'une de l'autre comme le montre la figure 2. Puisque les éléments décoratifs 1 sont associés aux éléments de liaison 7 par les moyens d'assemblage 9, ces éléments décoratifs sont empêchés de se dégager de la chaîne.When the bracelet is worn normally, that is to say when its roundness matches the curvature of the wrist, the cylindrical portions 5 and 6 are at least partially opposite one another as shown in Figure 2. Since the decorative elements 1 are associated with the connecting elements 7 by the assembly means 9, these decorative elements are prevented from being released from the chain.

Toujours selon la forme particulière d'exécution montrée au dessin et comme le mettent en évidence les figures 1 a et 1 b, l'axe d'articulation x d'un élément de liaison 7 sur l'élément voisin coïncide avec l'axe de la portion cylindrique concave 6 d'un élément décoratif.Still according to the particular embodiment shown in the drawing and as shown in FIGS. 1 a and 1 b, the axis of articulation x of a connecting element 7 on the neighboring element coincides with the axis of the concave cylindrical portion 6 of a decorative element.

L'élément de liaison 7 se présente sous la forme d'une plaque sensiblement rectangulaire teminée par un crochet 11 disposé sur l'un de ses grands côtés et par une ouverture 12 disposée sur le grand côté opposé. Crochet 11 et ouverture 12 composent la charnière 8. Les petits côtés de la plaque présentent chacun un coulisseau 13 adapté pour être engagé dans une coulisse borgne 14 pratiquée dans chacune des branches 2 et 3 de l'étrier. Ainsi, comme le montre la figure 1a, l'élément décoratif de droite 1 peut être dégagé de l'élément de liaison 7 seulement dans la direction de la flèche 10. De même la limita- fion de la longueur de la coulisse 14 positionne avec exactitude l'élément 7 par rapport à l'élément 1.The connecting element 7 is in the form of a substantially rectangular plate terminated by a hook 11 disposed on one of its long sides and by an opening 12 disposed on the opposite long side. Hook 11 and opening 12 make up the hinge 8. The short sides of the plate each have a slide 13 adapted to be engaged in a blind slide 14 formed in each of the branches 2 and 3 of the stirrup. Thus, as shown in FIG. 1a, the right decorative element 1 can be released from the connecting element 7 only in the direction of the arrow 10. Similarly, the limitation of the length of the slide 14 positions with accuracy of element 7 compared to element 1.

Très généralement, le bracelet selon l'invention comporte des éléments décoratifs 1 dont les faces latérales 5 et 6 sont conformées pour permettre le déverrouillage de deux éléments décoratifs quand le bracelet est plié au-delà d'un angle prédéterminé a, ce qui autorise au moins l'extraction d'un élément décoratif du bracelet et la mise en place d'un autre élément décoratif présentant par exemple un aspect esthétique différent. Ainsi, sans avoir recours à un outil quelconque, il va être possible au vendeur ou même à l'acheteur du bracelet de modifier à sa guise la composition de l'objet s'il dispose de deux ou d'une pluralité d'éléments décoratifs différents. On peut ainsi imaginer un bracelet tout or ou tout acier ou encore présentant une alterance régulière d'éléments en or et en acier. On peut encore imaginer des éléments sur lesquels seraient rapportées, par sertissage par exemple, une ou plusieurs pierres précieuses.Very generally, the bracelet according to the invention comprises decorative elements 1 whose lateral faces 5 and 6 are shaped to allow the unlocking of two decorative elements when the bracelet is folded beyond a predetermined angle a, which allows the minus the extraction of a decorative element from the bracelet and the installation of another decorative element having for example a different aesthetic appearance. Thus, without having to use any tool, it will be possible for the seller or even the buyer of the bracelet to modify as desired the composition of the object if it has two or more decorative elements different. One can thus imagine an all-gold or all-steel bracelet or even having a regular alternation of gold and steel elements. One can still imagine elements on which would be reported, by crimping for example, one or more precious stones.

Comme on l'a déjà dit plus haut, l'âme intérieure supporte à elle seule l'effort mécanique de traction s'exerçant sur le bracelet. Il est donc possible d'utiliser des éléments décoratifs faits en matériaux durs et fragiles et qui ne supporteraient pas une telle contrainte s'ils étaient directement attachés l'un à l'autre. Il pourrait s'agir de saphir synthétique ou naturel, de matériaux céramiques polycristallins ou encore de métaux durs frittés à plus de 1000°C. Là également, le bracelet selon l'invention pourrait porter une grande variété d'élément décoratifs réalisés avec ces matériaux particuliers pris seuls ou en combinaison.As already mentioned above, the inner core alone supports the mechanical tensile force exerted on the bracelet. It is therefore possible to use decorative elements made of hard and fragile materials and which would not withstand such a constraint if they were directly attached to each other. It could be synthetic or natural sapphire, polycrystalline ceramic materials or even hard metals sintered at more than 1000 ° C. Again, the bracelet according to the invention could carry a wide variety of decorative elements made with these materials individuals taken alone or in combination.

Dans le particulier de faces latérals cylindriques comme illustrées aux dessins, du rayon de courbure r et de l'épaisseur totale h de l'élément décoratif 1 pris en combinaison, va dépendre l'angle a à partir duquel un élément 1 peut être extrait de la chaîne. Cela est illustré aux figures 3a et 3b qui sont des dessins géométriques de deux situations de choix différents des paramètres r et h donnés ci-dessus.In the particular of cylindrical lateral faces as illustrated in the drawings, the radius of curvature r and the total thickness h of the decorative element 1 taken in combination, will depend on the angle a from which an element 1 can be extracted from chain. This is illustrated in FIGS. 3a and 3b which are geometric drawings of two different choice situations of the parameters r and h given above.

La figure 3a montre deux éléments décoratifs l' et 1" juxtaposés. Pour rendre possible le dégagement de l'élément 1', il sera nécessaire de plier l'élément 1 " par rapport à l'élément 1' d'un angle a = 85°. Si l'on désigne par r le rayon de courbure des éléments l' et 1 " et par h l'épaisseur totale des mêmes éléments, si l'on admet que l'axe d'articulation x d'un élément sur l'autre est confondu avec l'axe de la portion cylindrique 5 de rayon r, et si l'axe x est placé au milieu de l'épaisseur h, on peut calculer que r doit être égal ou plus grand que h "2 /2 si l'on veut pouvoir dégager entièrement l'élément 1'. Ainsi pour un élément décoratif présentant une épaisseur h de 3,2 mm, le rayon de courbure r devra être égal ou supérieur à 2,25 mm.Figure 3a shows two decorative elements 1 'and 1 "juxtaposed. To make possible the release of the element 1', it will be necessary to fold the element 1" relative to the element 1 'at an angle a = 85 ° . If we denote by r the radius of curvature of the elements l 'and 1 "and by h the total thickness of the same elements, if we admit that the articulation axis x of one element on the other is confused with the axis of the cylindrical portion 5 of radius r, and if the axis x is placed in the middle of the thickness h, we can calculate that r must be equal or greater than h "2/2 if l 'we want to be able to fully release element 1'. Thus for a decorative element having a thickness h of 3.2 mm, the radius of curvature r must be equal to or greater than 2.25 mm.

La figure 3b montre des éléments décoratifs l' et 1 " de même épaisseur que celle choisie pour la figure 3a. Ici on a agrandi le rayon de courbure r. On voit que le dégagement de l'élément l' est déjà possible pour un angle a de 40°.FIG. 3b shows decorative elements l ′ and 1 "of the same thickness as that chosen for FIG. 3a. Here the radius of curvature r has been enlarged. It can be seen that the clearance of the element l is already possible for an angle a of 40 ° .

Si l'on revient maintenant aux figures 1 a à 1c, on voit que la plaque formant l'élément de liaison 7 comporte un seul crochet 11 qui est plié et est fait d'une pièce avec la plaque. Ce crochet s'étend sur plus de la moitié de la longueur du grand côté de ladite plaque. De même l'ouverture 12, adaptée en longueur au crochet 11, est étampée directement dans la plaque 7. Les coulisseaux 13 sont également découpés dans le prolongement du plan de la plaque. Leurs largeurs 1 sont choisies assez grandes pour éviter toute rotation de la plaque par rapport à l'élément décoratif et aux coulisses 14 dans lesquelles elles glissent. De cette façon, n'est autorisé un déplacement de l'élément décoratif 1 par rapport à la plaque 7 correspondante que selon une direction longitudinale 10, comme on l'a déjà mentionné plus haut.Returning now to FIGS. 1 a to 1 c, it can be seen that the plate forming the connecting element 7 has a single hook 11 which is folded and is made in one piece with the plate. This hook extends over more than half the length of the long side of said plate. Similarly the opening 12, adapted in length to the hook 11, is stamped directly in the plate 7. The slides 13 are also cut in the extension of the plane of the plate. Their widths 1 are chosen to be large enough to avoid any rotation of the plate relative to the decorative element and to the slides 14 in which they slide. In this way, movement of the decorative element 1 relative to the corresponding plate 7 is only authorized in a longitudinal direction 10, as already mentioned above.

La figure 1b montre encore que l'axe l'articulation x d'une plaque sur l'autre est situé dans un plan différent que le plan de la plaque proprement dite, cette dernière étant située dans le même plan que les coulisseaux 13. Il est clair qu'on pourrait avoir une situation où l'axe x serait situé dans le même plan que le plan de la plaque proprement dite sans s'écarter de l'objet de la présente invention.FIG. 1b also shows that the axis of articulation x from one plate to the other is located in a different plane than the plane of the plate itself, the latter being located in the same plane as the slides 13. It It is clear that one could have a situation where the x axis would be located in the same plane as the plane of the plate itself without departing from the object of the present invention.

La figure 4 est une vue en perspective qui montre comment on s'y prend pour enlever un maillon du bracelet. Le bracelet est ici limité à trois éléments décoratifs 1', 1" et 1 "'. Pour dégager l'élément 1" on plie d'un angle a l'élément 1 vers l'arrière de la figure. A ce moment, la face concave 6 de l'élément 1" ne se trouve plus engagée en regard de la face convexe 5 de l'élément 1 " et l'élément 1" peut être glissé hors de l'élément de liaison 7' dans le sens de la flèche 10 par glissement des coulisses 14 hors des coulisseaux 13. Il est alors possible de remplacer l'élément 1 par un autre élément, de couleur différente par exemple. La figure 4 montre encore qu'on peut décrocher la charnière 8 en alignant l'élément 1' sur l'élément 1 " ce qui permettra de séparer les éléments de liaison 7' et 7" l'un de l'autre puis de rallonger ou de raccourcir le bracelet à volonté sand l'aide d'outils. Cette opération, dite de mise de longueur, va être expliquée maintenant à l'aide des figures 5a à 5m.Figure 4 is a perspective view showing how to remove a link from the bracelet. The bracelet is here limited to three decorative elements 1 ', 1 "and 1"'. To release the element 1 ", the element 1 is bent at an angle towards the rear of the figure. At this moment, the concave face 6 of the element 1" is no longer engaged facing the face convex 5 of element 1 "and element 1" can be slid out of the connecting element 7 'in the direction of arrow 10 by sliding the slides 14 out of the sliders 13. It is then possible to replace the element 1 by another element, of different color for example. Figure 4 also shows that we can unhook the hinge 8 by aligning the element 1 'on the element 1 "which will separate the connecting elements 7 'and 7 "from each other and then lengthen or shorten the bracelet at will with the aid of tools. This operation, called length adjustment, will now be explained in using figures 5a to 5m.

Les figures 5a à 5m montrent schématiquement les opérations a effectuer quand on désire raccou- rir le bracelet d'un maillon. La figure 5a présente une suite de cinq éléments décoratifs 21 à 25 attachés ensemble par cinq éléments de liaison correspondants 71 à 75. On se donne pour objectif de raccourcir le bracelet par enlèvement des éléments 23 et 73. Pour cela, on plie le bracelet au-delà de l'angle prédéterminé a en faisant pivoter l'élément 73 sur l'élément 74 (figure 5b). Les faces latérales 5 et 6 des éléments 24 et 23 sont alors dégagés l'une de l'autre ce qui permet l'extraction de l'élément décoratif 23 dans le sens de la flèche p et conduit à ce qui est montré en figure 5c. On aligne ensuite les maillons restants comme cela est présenté en figure 5d ce qui permet de décrocher les éléments de liaison 73 et 74 l'un de l'autre (figure 5e). On place les éléments 24, 74 et 25, 75 en attente. On fait tourner l'élément de liaison 73 vers le bas de la figure ce qui permet d'enlever l'élément décoratif 22 selon le sens de la flèche q (figure 5f). On place l'élément 22 en attente (figure 5g). On redresse l'élément 73 à l'horizontale (figure 5h) ce qui permet de le décrocher de l'élément 72 (figure 5i). On relie l'élément 72 au groupe 74, 24, 75, 25 qui avait été mis en attente (figure 5j). On plie les éléments de liaison 72 et 74 selon l'angle a (figure 5k) ce qui permet de glisser selon le sens de la flèche f l'élément décoratif 72 (figure 51). Enfin on redresse le brace- . let (figure 5m) qui a été débarrassé de l'élément décoratif 23 et de son élément de liaison correspondant 73. L'exemple de raccourcissement qui vient d'être décrit fait comprendre qu'on peut enlever n'importe quel maillon de la chaîne. Cependant si le bracelet est destiné à porter une montre, on pourrait limiter l'arrangement selon l'invention à quelques maillons se trouvant du côté de la boîte de montre ou du côté du fermoir du bracelet.Figures 5a to 5m schematically show the operations to be carried out when it is desired to shorten the bracelet with a link. FIG. 5a presents a series of five decorative elements 21 to 25 attached together by five corresponding connecting elements 71 to 75. The aim is to shorten the bracelet by removing elements 23 and 73. To do this, we fold the bracelet to beyond the predetermined angle a by rotating the element 73 on the element 74 (FIG. 5b). The lateral faces 5 and 6 of the elements 24 and 23 are then released from each other which allows the extraction of the decorative element 23 in the direction of the arrow p and leads to what is shown in FIG. 5c . The remaining links are then aligned as shown in FIG. 5d, which makes it possible to unhook the connecting elements 73 and 74 from one another (FIG. 5e). The elements 24, 74 and 25, 75 are placed on hold. The connecting element 73 is rotated downwards in the figure, which makes it possible to remove the decorative element 22 in the direction of the arrow q (FIG. 5f). The element 22 is placed on hold (FIG. 5g). The element 73 is straightened horizontally (FIG. 5h), which makes it possible to unhook it from the element 72 (FIG. 5i). Element 72 is connected to group 74, 24, 75, 25 which had been put on hold (Figure 5j). The connecting elements 72 and 74 are folded at the angle a (FIG. 5k), which makes it possible to slide in the direction of the arrow f the decorative element 72 (FIG. 51). Finally we straighten the brace-. let (Figure 5m) which has been freed from the decorative element 23 and its corresponding connecting element 73. The example of shortening which has just been described makes it clear that any link in the chain can be removed . However, if the bracelet is intended to wear a watch, the arrangement according to the invention could be limited to a few links located on the side of the watch case or on the side of the bracelet clasp.

Le mode d'exécution qui a été décrit ci-dessus met l'accent sur des faces latérales arrondies, imbriquées les unes dans les autres quand le bracelet est porté normalement. Il est bien clair cependant que ces faces latérales pourraient avoir d'autres formes ne verrouillant pas aussi intimement que montré les maillons les uns à la suite des autres. Ces faces pourraient par exemple être plates ou être composées de deux ou d'une pluralité de portions plates sans s'écarter pour autant de l'objet de l'invention, l'essentiel résidant dans le fait que ces faces soient conformées pour verrouiller les éléments décoratifs entre eux quand le bracelet est porté normalement et pour déverrouiller au moins un de ces éléments quand le bracelet est plié au-delà de l'angle prédéterminé a.The embodiment which has been described above emphasizes rounded side faces, nested one inside the other when the bracelet is worn normally. It is clear, however, that these side faces could have other shapes that do not lock as intimately as shown the links one after the other. These faces could for example be flat or be composed of two or a plurality of flat portions without departing from the object of the invention, the essential being that these faces are shaped to lock the decorative elements between them when the bracelet is worn normally and to unlock at least one of these elements when the bracelet is folded beyond the predetermined angle a.

Suivant les matières utilisées pour les éléments composant le bracelet et les tolérances dimensionnelles adoptées pour les réaliser, on pourrait crain- dre que certains des éléments décoratifs ne s'échappent intempestivement des éléments de liaison qui les emprisonnent quand on enlève le bracelet du poignet. Pour éviter cela, on pourrait imaginer un système de crantage ou de serrage quelconque de l'élément décoratif sur l'élément de liaison qui exigerait un certain effort pour procéder à l'extraction de l'élément décoratif.Depending on the materials used for the elements making up the bracelet and the dimensional tolerances adopted to make them, it could be feared that some of the decorative elements may inadvertently escape from the connecting elements which trap them when the bracelet is removed from the wrist. To avoid this, one could imagine a system of notching or any clamping of the decorative element on the connecting element which would require some effort to carry out the extraction of the decorative element.

Très généralement le bracelet selon l'invention comporte une série d'éléments décoratifs associé à une âme intérieure pliable faite d'un seul tenant. Selon la forme d'exécution préférée décrite plus haut, cette âme intérieure est composée d'autant d'éléments de liaison qu'il y a d'éléments décoratifs, ces éléments de liaison étant attachés les uns à la suite des autres au moyen de charnières. Cependant l'invention n'est pas limitée à cette seule forme d'exécution.Very generally, the bracelet according to the invention comprises a series of decorative elements associated with a foldable inner core made in one piece. According to the preferred embodiment described above, this inner core is composed of as many connecting elements as there are decorative elements, these connecting elements being attached one after the other by means of hinges. However, the invention is not limited to this single embodiment.

L'âme intérieure pourrait être faite d'une seule bande allongée et flexible en acier ou en caoutchouc par exemple. De cette bande dépasseraient dans le sens de la largeur et à intervalles réguliers des coulisseaux 13. Dans ce cas c'est la flexibilité de la bande qui remplacerait les charnières à crochets décrites plus haut.The inner core could be made of a single elongated and flexible strip of steel or rubber for example. Of this strip would protrude in the width direction and at regular intervals of the slides 13. In this case it is the flexibility of the strip that would replace the hook hinges described above.

L'âme intérieure pourrait aussi être faite d'un seul tenant en caoutchouc à l'intérieur duquel seraient retenues prisonniers des plaques en acier disposées transversalement à l'âme et dépassant de celle-ci pour jouer le rôle des coulisseaux 13. Une plaque serait prévue par élément décoratif.The inner core could also be made in one piece of rubber inside which would be held captive steel plates arranged transversely to the core and protruding from it to play the role of the slides 13. A plate would be provided by decorative element.

Les deux variantes envisagées ci-dessus pourraient convenir dans le cas où n'est envisagée que la modification esthétique du bracelet. Le raccourcissement pourrait cependant être facilement envisagé dans le cas où l'âme intérieure est en caoutchouc. Il suffirait alors de couper une section de l'âme, côté fermoir ou boîte, d'une longueur correspondante à un ou à plusieurs éléments décoratifs.The two variants envisaged above could be suitable in the case where only the aesthetic modification of the bracelet is envisaged. The shortening could however be easily envisaged in the case where the inner core is made of rubber. It would then suffice to cut a section of the core, on the clasp or box side, of a length corresponding to one or more decorative elements.
