Abstract

The bracelet is made up of two rows (2, 4) of outer links and a row (6) of central links which are staggered by half the width of a link from those in the outer rows. Each central link (7) is connected to two links in each outer row (3, 5, 17, 18) by one threaded rod (19) and one rod (10) with sprung ends. Each rod is fitted into a bore across the total width of the central link and fits into bores in the outer links. An Independent claim is included for a method for assembling a bracelet as described above.

Description

La présente invention est relative à un bracelet à maillons articulés comprenant une première rangée de maillons latéraux marquant le premier bord du bracelet, une deuxième rangée de maillons latéraux marquant le second bord du bracelet, les maillons de cette deuxième rangée étant alignés sur les maillons de la première, deux maillons alignés définissant un pas du développement longitudinal du bracelet, et au moins une troisième rangée de maillons centraux intercalés entre les maillons des première et deuxième rangées et décalés d'un demi-pas par rapport aux maillons desdites première et deuxième rangées, chaque maillon des première et deuxième rangées comportant d'une part et respectivement des premier et deuxième trous disposés en alignement avec un troisième trou traversant percé dans un premier maillon de la troisième rangée et d'autre part et respectivement des quatrième et cinquième trous disposés en alignement avec un sixième trou traversant percé dans un second maillon de la troisième rangée, ce second maillon jouxtant le premier, une première barrette étant engagée dans les premier, deuxième et troisième trous et une seconde barrette étant engagée dans les quatrième, cinquième et sixième trous.The present invention relates to an articulated link bracelet comprising a first row of side links marking the first edge of the bracelet, a second row of side links marking the second edge of the bracelet, the links of this second row being aligned with the links of the first, two aligned links defining a step in the longitudinal development of the bracelet, and at least a third row of central links interposed between the links in the first and second rows and offset by half a step from the links of said first and second rows, each link of the first and second rows, second rows comprising first and second respectively first and second holes arranged in alignment with a third through hole drilled in a first link of the third row and second and fourth and fourth respectively fifth holes arranged in alignment with a sixth through hole drilled in a second link in the third row, this second link next to the first, a second first bar being engaged in the first, second and third holes and a first second bar being engaged in the fourth, fifth and sixth holes.

Un assemblage de maillons tel que décrit au paragraphe ci-dessus est donné comme art antérieur dans le document US 5,197,274. Cet assemblage comporte trois rangées de maillons, notamment une rangée supérieure, une rangée centrale et une rangée inférieure. Les maillons des rangées supérieure et inférieure sont alignés alors que les maillons de la rangée centrale sont décalés par rapport aux maillons des autres rangées. Chaque maillon de la rangée centrale est percé de deux trous traversants et chaque maillon des rangées supérieure et inférieure est percé de deux trous, l'un traversant et l'autre borgne. D'une part, un trou traversant d'un premier maillon de la rangée centrale est aligné avec deux trous traversants percés respectivement dans un maillon de la rangée supérieure et dans un maillon de la rangée inférieure, d'où il résulte trois trous alignés dans lesquels est engagée une première barrette retenue dans le maillon de la rangée centrale par un manchon à étranglement. D'autre part, un trou traversant d'un second maillon de la rangée centrale est aligné avec deux trous borgnes percés respectivement dans le maillon de la rangée supérieure et dans le maillon de la rangée inférieure, d'où il résulte trois trous alignés dans lesquels est engagée une seconde barrette retenue par chassage dans chacun des maillons des rangées supérieure et inférieure.An assembly of links as described in the paragraph above is given as prior art in US 5,197,274. This assembly has three rows of links, in particular an upper row, a central row and a row lower row. The links of the upper and lower rows are aligned then that the links in the central row are offset from the links of the other rows. Each link in the central row is pierced with two holes through and each link in the upper and lower rows is pierced with two holes, one through and the other one-eyed. On the one hand, a through hole of a first link of the central row is aligned with two drilled through holes respectively in a link of the upper row and in a link of the lower row, resulting in three aligned holes in which is engaged a first bar retained in the link of the central row by a sleeve to constriction. On the other hand, a through hole of a second link in the row central is aligned with two blind holes drilled respectively into the the top row and in the link of the lower row, from which it results three aligned holes in which is engaged a second bar retained by driving in each of the links of the upper and lower rows.

L'assemblage décrit ci-dessus présente cependant plusieurs inconvénients. On notera d'abord que la retenue par étranglement de la première barrette dans le premier maillon de la rangée centrale exerce une contrainte mécanique non négligeable sur ce maillon, ce qui peut le faire éclater s'il est fait en matière friable et cassante, par exemple de la céramique. On notera encore que le chassage de la second barrette dans chacun des seconds maillons des rangées supérieure et inférieure exerce sur ces derniers une contrainte encore plus accentuée de telle sorte qu'ils peuvent également voler en éclat lors de cette opération si, comme on l'a déjà dit, ces maillons sont faits en une matière friable et cassante. On notera enfin que le chassage n'est pas considéré comme une retenue suffisamment sûre puisqu'à la suite de mouvements exercés sur le bracelet, la barrette peut être déchassée de ses sièges.The assembly described above, however, has several disadvantages. It will first be noted that the throttling restraint of the first bar in the first link of the central row exerts a mechanical stress not negligible on this link, which can cause it to burst if it is made of friable material and brittle, for example ceramic. It will be noted that the hunting of the second bar in each of the second links of the upper and lower rows the lower one exerts a greater stress on the latter in such a way that that they can also shatter during this operation if, as we already have said, these links are made of a friable and brittle material. Finally, note that the hunting is not considered a sufficiently safe restraint since at Following movements on the bracelet, the bar can be released from its seats.

Pour remédier aux inconvénients cités au paragraphe ci-dessus le document US 5,197,274 cité plus haut propose de visser les barrettes dans les maillons d'une rangée latérale et de les maintenir bloqués au moyen de goujons vissés dans l'autre rangée latérale. Cette construction est compliquée tant par le nombre de pièces qu'elle nécessite que par le temps qui doit être consacré à l'assemblage du bracelet, sans compter le risque toujours présent de dévissage du goujon ce qui oblige alors de le bloquer par de la colle. En fait, il est apparu au déposant de la présente invention qu'une des barrettes en question pouvait très bien être vissée directement dans les maillons alignés des deux rangées latérales.To overcome the disadvantages mentioned in the paragraph above, the document US 5,197,274 cited above proposes to screw the bars in the links of a side row and keep them locked by means of studs screwed into each other side row. This construction is complicated both by the number of pieces that it requires only the time that must be devoted to the assembly of the bracelet, not to mention the risk still present of unscrewing the stud which then forces block it with glue. In fact, it appeared to the applicant of the present invention that one of the bars in question could very well be screwed directly into the aligned links of the two lateral rows.

En conclusion de ce qui précède, et en relation avec le premier paragraphe de cette description, la présente invention est remarquable en ce sens que la seconde barrette est filetée au moins à ses extrémités pour être vissée dans des taraudages pratiqués dans les quatrième et cinquième trous percés respectivement dans les maillons des première et deuxième rangées.In conclusion of the above, and in relation to the first paragraph of this description, the present invention is remarkable in that the second bar is threaded at least at its ends to be screwed into threads practiced in the fourth and fifth holes drilled respectively in the links of the first and second rows.

La présente invention est aussi remarquable par le procédé d'assemblage des différents éléments constituant le bracelet, procédé qui sera décrit en détail dans la description qui va suivre.The present invention is also remarkable for the method of assembling different elements constituting the bracelet, a process which will be described in detail in the description that will follow.

Les caractéristiques et avantages de l'invention ressortiront maintenant de la description qui va suivre, faite en regard du dessin annexé et donnant à titre explicatif, mais nullement limitatif, une forme avantageuse de réalisation de l'invention, dessins dans lesquels :

  • la figure 1 est une vue en perspective du bracelet de l'invention, et
  • la figure 2 est une coupe vue en plan d'une partie du bracelet montré en figure 1.
The features and advantages of the invention will become apparent from the description which follows, given with reference to the appended drawing and giving by way of explanation, but in no way limiting, an advantageous embodiment of the invention, drawings in which:
  • FIG. 1 is a perspective view of the bracelet of the invention, and
  • Figure 2 is a sectional plan view of a portion of the bracelet shown in Figure 1.

Comme on le voit sur les figures 1 et 2, le bracelet 1 à maillons articulés 3, 5, 17, 18, 7, 16 comprend une première rangée 2 de maillons latéraux 3, 17 qui marquent le premier bord du bracelet 1. Le bracelet 1 comporte encore une deuxième rangée 4 de maillons latéraux 5, 18 qui marquent le second bord du bracelet 1. Les figures 1 et 2 montrent que les maillons des première et deuxième rangées sont alignés l'un par rapport à l'autre, deux maillons alignés, par exemple les maillons 3 et 5, définissant un pas du développement longitudinal du bracelet. Le bracelet 1 comporte enfin au moins une troisième rangée 6 de maillons centraux 7, 16 qui sont intercalés entre les maillons des première et deuxième rangées et qui sont décalés d'un demi-pas par rapport aux maillons desdites première et deuxième rangées.As can be seen in FIGS. 1 and 2, the link bracelet 1 with articulated links 3, 5, 17, 18, 7, 16 comprises a first row 2 of side links 3, 17 which mark the first edge of the bracelet 1. The bracelet 1 still has a second row 4 side links 5, 18 which mark the second edge of the bracelet 1. The Figures 1 and 2 show that the links of the first and second rows are aligned with each other, two aligned links, for example the links 3 and 5, defining a step of the longitudinal development of the bracelet. The bracelet 1 finally has at least a third row 6 of central links 7, 16 which are interposed between the links of the first and second rows and which are offset a half-step relative to the links of said first and second rows.

On remarquera qu'ici une seule rangée de maillons centraux est représentée. Sans qu'il soit nécessaire de le montrer, on comprendra qu'on pourrait avoir d'autres rangées de maillons centraux, par exemple trois rangées au lieu d'une seule ou encore cinq rangées au lieu d'une seule. Dans le cas de trois rangées de maillons centraux, on aurait dans l'ordre un premier maillon latéral, un deuxième maillon central décalé par rapport au premier, un troisième maillon central en phase avec le premier, un quatrième maillon central décalé par rapport au premier et un cinquième maillon latéral en phase avec le premier, l'essentiel à prendre en compte étant un nombre impair de rangées de maillons centraux décalés les uns par rapport aux autres.It will be noticed that here only one row of central links is represented. Without it being necessary to show it, we will understand that we could have other rows of central links, for example three rows instead of one or five more rows instead of one. In the case of three rows of links central, we would have in order a first side link, a second link center offset from the first, a third central link in phase with the first, a fourth central link offset from the first and a fifth side link in phase with the first, the essential to take into account being a an odd number of rows of central links staggered with respect to other.

Comme le montre la figure 2, chaque maillon aligné des première et deuxième rangées, par exemple les maillons 3 et 5, comporte d'une part et respectivement des premier et deuxième trous 8 et 9 disposés en alignement avec un troisième trou traversant 10 percé dans un premier maillon 7 de la troisième rangée 6. Chaque maillon aligné des première et deuxième rangées, par exemple les maillons 3 et 5, comporte d'autre part et respectivement des quatrième et cinquième trous 11 et 12 disposés en alignement avec un sixième trou traversant 13 percé dans un second maillon 16 de la troisième rangée 6, ce second maillon 16 jouxtant le premier maillon 7.As shown in Figure 2, each aligned link of the first and second rows, for example links 3 and 5, comprises on the one hand and respectively first and second holes 8 and 9 arranged in alignment with a third hole through 10 pierced in a first link 7 of the third row 6. Each aligned link of the first and second rows, for example links 3 and 5, on the other hand and respectively fourth and fifth holes 11 and 12 arranged in alignment with a sixth through hole 13 pierced in a second link 16 of the third row 6, this second link 16 adjoining the first link 7.

Enfin, une première barrette 14 est engagée dans les premier, deuxième et troisième trous 8, 9 et 10 et une seconde barrette 15 est engagée dans les quatrième, cinquième et sixième trous 11, 12 et 13.Finally, a first bar 14 is engaged in the first, second and third holes 8, 9 and 10 and a second bar 15 is engaged in the fourth, fifth and sixth holes 11, 12 and 13.

Comme le montre toujours la figure 2, l'invention est remarquable et originale par le fait que la seconde barrette 15 est filetée au moins à ses extrémités pour être vissée dans des taraudages pratiqués dans les quatrième et cinquième trous 11 et 12 qui sont percés respectivement dans les maillons 3 et 5 des première et deuxième rangées 2 et 4. La liaison entre deux maillons latéraux 3 et 5, entre lesquels est intercalé un maillon central 16, est ainsi réalisée au moyen d'une simple barrette 15 filetée au moins dans ses extrémités et vissée dans des taraudages pratiqués dans les trous 11 et 12 percés dans les maillons latéraux 3 et 5. On a obtenu ainsi une première section ou un premier pas du bracelet. As always shown in Figure 2, the invention is remarkable and original in that the second bar 15 is threaded at least at its ends to be screwed into threads in the fourth and fifth holes 11 and 12 which are pierced respectively in links 3 and 5 of the first and second rows 2 and 4. The connection between two side links 3 and 5, between which is intercalated a central link 16, is thus achieved by means of a simple bar 15 threaded at least in its ends and screwed into threads made in holes 11 and 12 pierced in the side links 3 and 5. This gave a first section or a first step of the bracelet.

La figure 2 montre une seconde section du bracelet, de même facture, et qui comprend l'assemblage des deux maillons latéraux 17 et 18 entre lesquels prend place le maillon central 7. Les moyens d'assemblage comprennent ici la barrette vissée 19.Figure 2 shows a second section of the bracelet, of the same invoice, and which comprises assembling the two side links 17 and 18 between which place the central link 7. The assembly means here comprise the bar screwed 19.

Les deux sections du bracelet qu'on vient de décrire sont assemblées au moyen d'une barrette 14 comme le montre la figure 2. On peut utiliser une barrette à ressort comme présentée sur la figure. Cette barrette comporte en sa partie centrale un ressort (non représenté) qui agit sur deux têtes mobiles 20 et 21. Quand la barrette 14 est en place, les têtes 20 et 21 sont projetées dans les trous 8 et 9 des maillons 3 et 5. On a ainsi rendu solidaires les deux sections tout en permettant l'articulation de l'une sur l'autre.The two sections of the bracelet just described are assembled at by means of a bar 14 as shown in FIG. spring as shown in the figure. This bar has in its central part a spring (not shown) which acts on two movable heads 20 and 21. When the bar 14 is in place, the heads 20 and 21 are projected in the holes 8 and 9 of the links 3 and 5. The two sections have been made integral while allowing the articulation of one over the other.

La figure 2 montre que les premier et deuxième trous 8 et 9 sont traversants ce qui permet, en repoussant les têtes 20 et 21 de la barrette 14 au moyen d'un petit outil, de désassembler les première et seconde sections pour allonger ou raccourcir à volonté la longueur du bracelet. Sur un bracelet habituel (voir figure 1), on s'arrangera pour qu'au moins certains maillons (par exemple trois ou quatre maillons situés du côté du fermoir du bracelet) constituant les première et deuxième rangées comprennent des trous traversants 8 et 9, alors que les maillons suivants seront pourvus de trous borgnes, cela étant mis en oeuvre dans un but esthétique de cacher ces trous suivants au regard. Bien sûr qu'une fois montées, les sections équipées de maillons à trous borgnes ne seront plus démontables.Figure 2 shows that the first and second holes 8 and 9 are through which allows, by pushing the heads 20 and 21 of the bar 14 by means of a small tool, to disassemble the first and second sections to lengthen or shorten to will the length of the bracelet. On a usual bracelet (see Figure 1), we will arrange for at least some links (for example three or four links located side of the bracelet clasp) constituting the first and second rows include through holes 8 and 9, while the following links will be provided with blind holes, this being implemented for the aesthetic purpose of hiding these next holes to look at. Of course once assembled, the sections equipped with links with blind holes will no longer be removable.

Si l'on revient maintenant aux quatrième et cinquième trous taraudés 11 et 12 dans les maillons 3 et 5 des première et deuxième rangée 2 et 4, on observera que ces trous peuvent être borgnes ou traversants. Pour des raisons d'esthétique et comme cela est montré en figure 2, on préférera des trous borgnes, auquel cas la barrette 15 peut être filetée soit dans toute sa longueur, soit seulement à ses extrémités. Dans le cas cependant où l'on opterait pour des trous taraudés 11 et 12 traversants, on n'utilisera que des barrettes 15 filetées à leurs extrémités seulement pour éviter tout dévissage intempestif desdites barrettes 15.If we go back now to the fourth and fifth tapped holes 11 and 12 in links 3 and 5 of the first and second rows 2 and 4, it will be observed that these holes can be blind or through. For aesthetic reasons and as shown in Figure 2, blind holes are preferred, in which case the bar 15 may be threaded either in its entire length or only at its extremities. In the case however where one would opt for tapped holes 11 and 12 only threaded bars at their ends only to avoid any unwanted unscrewing of said bars 15.

Pour réaliser les maillons composant le bracelet de l'invention un vaste éventail de matières peut être envisagé, par exemple de l'acier. Cette construction cependant est particulièrement bien adaptée si les maillons qui constituent les première, deuxième et troisième rangées 2, 4 et 6 sont réalisés en céramique injectée.To make the links composing the bracelet of the invention a vast range of materials can be envisaged, for example steel. This construction However, it is particularly well adapted if the links which constitute the first, second and third rows 2, 4 and 6 are made of ceramic injected.

Sans entrer dans les détails, on mentionnera ici que pour exécuter un maillon en céramique injectée, on utilise une poudre de céramique à laquelle on mélange un liant plastique. Cette matière composite est alors injectée dans un moule qui est chauffé dans le but de se débarrasser du liant plastique. La pièce obtenue est alors fritée à haute température pour obtenir la cohésion de la poudre de céramique, puis le maillon attendu. Ceci permet donc, non seulement d'obtenir les contours voulus du maillon, mais encore les trous percés dans ce maillon qu'ils soient traversants ou borgnes, taraudés ou lisses.Without going into details, we will mention here that to execute a link injected ceramic, a ceramic powder is used, to which a mixture of plastic binder. This composite material is then injected into a mold which is heated in order to get rid of the plastic binder. The piece obtained is then fried at high temperature to obtain the cohesion of the ceramic powder, then the expected link. This allows, therefore, not only to obtain the desired contours of the link, but still the holes drilled in this link that they are through or blind, tapped or smooth.

Visser une barrette filetée 15 dans les trous taraudés 11 et 12 des maillons latéraux 3 et 5 n'exerce sur ces derniers aucune contrainte mécanique qui pourrait les faire éclater s'ils sont faits en céramique. Il en va de même de la barrette à ressort 14 qui n'exerce, une fois en place, aucune contrainte sur les mêmes maillons. L'utilisation de céramique injectée permet aussi de produire des maillons réalisés selon l'invention sans avoir recours à un usinage mécanique quelconque ce qui est coûteux lorsqu'on utilise un tel matériau.Screw a threaded bar 15 into the threaded holes 11 and 12 of the links side plates 3 and 5 exerts on them no mechanical constraint which could burst if they are made of ceramic. The same is true of the spring bar 14 who does not exercise, once in place, any constraint on the same links. Use Injected ceramic also makes it possible to produce links made according to the invention. without resorting to any mechanical machining which is expensive when uses such a material.

On mentionnera encore que la construction proposée est très économique par la simplicité et le peu de pièces qu'elle met en oeuvre soit des maillons latéraux tous fabriqués de la même façon, des maillons centraux, des barrettes à ressort et des barrettes filetées.It will be mentioned that the proposed construction is very economical the simplicity and the few parts it uses are side links all made in the same way, central links, spring loaded bars and threaded bars.

On terminera cette description en exposant le procédé d'assemblage du bracelet de l'invention. On se référera pour cela à la figure 2.This description will be completed by exposing the assembly process of the bracelet of the invention. For this purpose, see Figure 2.

On commence par fournir un maillon latéral 3 pour débuter la première rangée 2, puis on visse dans le trou taraudé 11 de ce maillon la seconde barrette 15 filetée au moins à ses deux extrémités. On fournit ensuite un premier maillon central 16 pour débuter la première rangée 6, puis on enfile par son extrémité libre la seconde barrette 15 dans un des deux trous 13 du maillon central. On fournit enfin un maillon latéral 5 pour débuter la deuxième rangée 4, puis on visse, en le faisant pivoter, ce maillon latéral sur la seconde barrette 15 en introduisant la partie filetée de cette dernière dans le trou taraudé 12 du même maillon latéral. On a ainsi réalisé une première section du bracelet.We start by providing a side link 3 to start the first row 2, and then screwed into the threaded hole 11 of this link the second bar 15 threaded at less at both ends. We then provide a first central link 16 for start the first row 6, then put on its free end the second bar 15 in one of the two holes 13 of the central link. Finally, we provide a link side 5 to start the second row 4, then we screw, by rotating, this side link on the second bar 15 by introducing the threaded portion of this last in the tapped hole 12 of the same side link. We thus realized a first section of the bracelet.

On assemble une seconde section de la même manière que celle qui vient d'être décrite, cette seconde section étant elle aussi composée de deux maillons latéraux 17 et 18, d'un second maillon central 7, ces trois maillons étant reliés ensemble par une barrette vissée 19. On introduit alors dans un trou traversant 10 du second maillon central 7 une barrette à ressort 14.We assemble a second section in the same way as the one that comes to be described, this second section is also composed of two links 17 and 18, of a second central link 7, these three links being connected together by a screwed bar 19. It is then introduced into a through hole 10 of second central link 7 a spring bar 14.

On assemble enfin les première et seconde sections en faisant pénétrer le second maillon central 7 de la seconde section dans l'espace défini par les deux maillons latéraux 3 et 5 et le maillon central 16 de la première section. Les têtes 20 et 21 que comporte la barrette à ressort 14 pénètrent alors dans les premier et deuxième trous 8 et 9 qui équipent respectivement les maillons latéraux 3 et 5 de la première section.Finally, the first and second sections are assembled by penetrating the second central link 7 of the second section in the space defined by the two side links 3 and 5 and the central link 16 of the first section. The heads 20 and 21 that includes the spring bar 14 penetrate then in the first and second holes 8 and 9 which respectively equip the side links 3 and 5 of the first section.

Finalement on assemble de la même manière d'autre sections jusqu'à obtenir la longueur désirée du bracelet.Finally we assemble in the same way other sections until we get the desired length of the bracelet.

Les figures 1 et 2 montrent en outre comment le bracelet ainsi assemblé peut être relié à un fermoir par exemple. A cet effet, la figure 2 montre un maillon 25 étendu sur toute la longueur du bracelet et percé d'un trou 26 destiné à recevoir une barrette finale (non représentée) traversant aussi une portion du fermoir (non représenté). Ce maillon 25 est articulé sur un maillon central 22 au moyen d'une barrette à ressort 23. Le maillon central 22 est articulé à son tour sur les maillons latéraux 17 et 18 au moyen d'une barrette à ressort 24.Figures 1 and 2 also show how the assembled bracelet can be connected to a clasp for example. For this purpose, Figure 2 shows a link 25 extended over the entire length of the bracelet and pierced with a hole 26 for receiving a final bar (not shown) also passing through a portion of the clasp (no represent). This link 25 is articulated on a central link 22 by means of a spring bar 23. The central link 22 is articulated in turn on the links laterals 17 and 18 by means of a spring bar 24.
