Description

Domaine techniqueTechnical area

L'invention se rapporte au domaine des assemblages élastiques, notamment à celui des bracelets et bagues élastiques, plus particulièrement métalliques.The invention relates to the field of elastic assemblies, in particular to that of elastic bracelets and rings, more particularly metallic.

Technique antérieurePrior art

Il existe de nombreux assemblages élastiques, notamment métalliques, et particulièrement de bracelets, constitués d'éléments rigides reliés entre eux par des éléments à ressort. La plupart de ces bracelets sontfaits de minces feuilles métalliques pliées de façon à former des éléments creux susceptibles de recevoir le mécanisme à ressort. Il n'existe pas actuellement d'assemblage élastique de ce genre, notamment et particulièrement de bracelets ou de bagues métallique, fait d'éléments massifs, d'une épaisseur de 2 ou 3 mm, et dont le mécanisme soit intégré de manière élégante. Le montage et le démontage des assemblages actuellement existants, de même que l'adaptation de leur longueur, notamment l'adaptation de la longueur d'un bracelet au poignet porteur, ou d'une bague à un doigt sont en outre compliqués.There are many elastic assemblies, notably metallic, and in particular bracelets, made up of rigid elements linked together by spring elements. Most of these bracelets are made of thin metal sheets folded so as to form hollow elements capable of receiving the spring mechanism. There is currently no such elastic assembly, in particular and particularly of bracelets or metal rings, made of massive elements, with a thickness of 2 or 3 mm, and whose mechanism is elegantly integrated. The assembly and disassembly of currently existing assemblies, as well as the adaptation of their length, in particular the adaptation of the length of a bracelet to the carrying wrist, or of a ring to a finger are further complicated.

La présente invention a pour objet de permettre la construction d'un tel assemblage, facile à monter et à démonter, et présentant un aspect esthétique. Elle peut s'appliquer par exemple à la construction d'un bracelet ou d'une bague.The present invention aims to allow the construction of such an assembly, easy to assemble and disassemble, and having an aesthetic appearance. It can be applied for example to the construction of a bracelet or a ring.

Exposé de l'inventionStatement of the invention

L'assemblage comprend des éléments rigides 1, qui peuvent être faits d'une pièce ou résulter de l'assemblage de plusieurs composants. Chaque élément rigide présente ou moins une cavité 3 ouverte sur l'élément rigide adjacent, qui présente lui-même au moins une cavité correspondante. La forme d'exécution préférée et la plus simple de l'invention est celle des fig. 1 à 5, dans lesquelles la cavité 3 traverse l'élément rigide d'une bord à l'autre (revendication 3), et présente des parois droites. Dans au moins l'une de ces parois latérales est pratiqué au moins un trou 4. La fig. 1 montre une forme d'exécution dans laquelle chaque paroi présente deux trous (revendication 7), tandis que la fig. 6 montre une forme d'exécution dans laquelle chaque paroi n'a qu'un trou. La cavité 3 est ouverte dans les formes d'exécution représentées dans les fig. 1 à 3, 5 à 8; il est cependant possible de la recouvrir de façon qu'elle ne s'ouvre que latéralement, en direction de l'élément adjacent (fig. 9). Un tel recouvrement présente l'avantage de donner à l'assemblage, par exemple un bracelet, sur ses deux faces, un aspect identique et lisse. Toutefois la contruction est alors plus complexe, et le montage et le démontage de l'assemblage moins faciles. La cavité 3 est conformée de façon à recevoir, au moins partiellement, au moins un élément de liaison 2. Dans la forme d'exécution préférée des fig. 1 à 5, l'élément de liaison 2 présente la forme d'un tube aplati de mêmes dimensions approximatives que la cavité 3, quoique légèrement moins large, de façon à pouvoir rentrer dans celle-ci. L'élément de liaison est formé, dans cette forme d'exécution-là, d'un tube aplati aux parois minces, de préférence en métal. L'élément de liaison présente au moins une ouverture latérale 7 qui fait face au trou 4 lors de l'introduction de l'élément de liaison dans la cavité 3. Dans la forme d'exécution préférée des fig. 1 à 3, 5, 6, 8 et 9, le tube formant le corps de l'élément de liaison présente deux ouvertures latérales 7; au moins un tenon 5 émerge de ces ouvertures, fixé par l'intermédiaire de moyens élastiques 6 au corps de l'élément de liaison ffig.1 à 5). Dans une autre forme (fig. 7), moins favorable, l'ouverture 7 est pratiquée dans la paroi latérale de la cavité et le ou les tenons fixés au fond de cette ouverture, également par l'intermédiaire de moyens élastiques 6. Dans les formes d'exécution présentées dans les dessins, les moyens élastiques sont combinés avec le tenon en une seule pièce élastique ou ressort (revendication 5). Cette pièce est de préférence métallique, mais elle pourrait également être faite d'une matière synthétique élastique. Dans la forme d'exécution préférée des fig. 1 à 4, l'élément de liaison comprend un ressort, formé de quatre bras en forme de S, selon les revendications 9 et 20, les bouts de chacun de ces bras constituant les tenons 5 et dépassant par paires des deux ouvertures 7. Dans la forme d'exécution de la fig. 7, les tenons sont aussi les deux bouts d'un ressort, dont la partie centrale est placée au fond de l'ouverture 7, les deux tenons dépassant dans la cavité 3.The assembly comprises rigid elements 1, which can be made in one piece or result from the assembly of several components. Each rigid element has at least one cavity 3 open on the adjacent rigid element, which itself has at least one corresponding cavity. The preferred and simplest embodiment of the invention is that of FIGS. 1 to 5, in which the cavity 3 crosses the rigid element from one edge to the other (claim 3), and has straight walls. In at least one of these side walls is made at least one hole 4. FIG. 1 shows an embodiment in which each wall has two holes (claim 7), while FIG. 6 shows an embodiment in which each wall has only one hole. The cavity 3 is open in the embodiments shown in FIGS. 1 to 3, 5 to 8; it is however possible to cover it so that it only opens laterally, towards the adjacent element (fig. 9). Such a covering has the advantage of giving the assembly, for example a bracelet, on its two faces, an identical and smooth appearance. However, the construction is more complex, and the assembly and disassembly of the assembly less easy. The cavity 3 is shaped so as to receive, at least partially, at least one connecting element 2. In the preferred embodiment of FIGS. 1 to 5, the connecting element 2 has the form of a flattened tube of the same approximate dimensions as the cavity 3, although slightly narrower, so as to be able to enter it. The connecting element is formed, in this embodiment, of a flattened tube with thin walls, preferably made of metal. The connecting element has at least one lateral opening 7 which faces the hole 4 when the connecting element is introduced into the cavity 3. In the preferred embodiment of FIGS. 1 to 3, 5, 6, 8 and 9, the tube forming the body of the connecting element has two lateral openings 7; at least one stud 5 emerges from these openings, fixed by means of elastic means 6 to the body of the connecting element ffig.1 to 5). In another, less favorable form (FIG. 7), the opening 7 is made in the side wall of the cavity and the stud (s) fixed to the bottom of this opening, also by means of elastic means 6. In the As shown in the drawings, the elastic means are combined with the post in a single elastic piece or spring (claim 5). This part is preferably metallic, but it could also be made of an elastic synthetic material. In the preferred embodiment of Figs. 1 to 4, the connecting element comprises a spring, formed of four S-shaped arms, according to claims 9 and 20, the ends of each of these arms constituting the pins 5 and projecting in pairs from the two openings 7. In the embodiment of fig. 7, the studs are also the two ends of a spring, the central part of which is placed at the bottom of the opening 7, the two studs protruding into the cavity 3.

Dans les formes d'exécution représentées ici, les tenons dépassent obliquement de l'ouverture 7, de façon à glisser contre l'élément auquel ils ne sont pas fixés, lors de l'introduction de l'élément de liaison dans la cavité 3.In the embodiments shown here, the pins project obliquely from the opening 7, so as to slide against the element to which they are not fixed, during the introduction of the connecting element into the cavity 3.

Dans la forme d'exécution préférée des fig. 1 à 5 et 8 et 9, les tenons et les moyens élastiques sont faits d'une pièce étampée ou découpée par attaque chimique'facile à fabriquer. La forme en S des bras du ressort donne à celui-ci la longueur nécessaire pour assurer une flexibilité suffisante.In the preferred embodiment of Figs. 1 to 5 and 8 and 9, the tenons and the elastic means are made of a stamped or cut piece by chemical attack, which is easy to manufacture. The S-shape of the spring arms gives it the necessary length to ensure sufficient flexibility.

Le ressort représente aux fig. 1 et 4 présente en son centre un petit trou ou dépression 12. Cette dépression est destinée à permettre la fixation du ressort dans l'élément de liaison par un enfoncement de la paroi du tube dans cette dépression. Toutefois, cela n'est pas indispensable: il paraît suffisant de donner au ressort une largeur légèrement supérieure à celle de l'intérieur du tube, de façon que le ressort est fixé par la force du frottement qu'il exerce sur la paroi interne du tube formant l'élément de liaison 2.The spring shown in Figs. 1 and 4 has in its center a small hole or depression 12. This depression is intended to allow the fixing of the spring in the connecting element by a depression of the wall of the tube in this depression. However, this is not essential: it seems sufficient to give the spring a width slightly greater than that of the interior of the tube, so that the spring is fixed by the force of the friction which it exerts on the internal wall of the tube forming the connecting element 2.

La réunion des éléments de liaison avec les éléments rigides se fait très simplement, en plaçant l'élément de liaison sur le côté de la cavité 3, dans le même plan que l'élément rigide, et en l'enfonçant dans cette cavité. Lors de cette introduction, le ou les tenons rencontrent le bord 8 de l'élément rigide (au cas où le tenon est fixé à l'élément de liaison, fig. 1 à 6), ou le bord 8 de l'élément de liaison (au cas où le tenon est fixé à l'élément rigide, fig. 7). Le tenon, placé obliquement, cède grâce à la flexion des moyens élastiques 6 et s'efface dans l'ouverture 7. Lorsque l'extrémité du tenon se trouve en face du trou 4, elle va se loger dans ce trou sous l'effet de la détente des moyens élastiques, c'est-à-dire, dans les formes d'exécution représentées ici, du ressort. Dans les formes d'exécution des fig. 1 à 3, 5 à 9, les éléments de liaison sont dimensionnés de manière qu'ils se touchent au milieu de la cavité 3. La fixation d'un élément de liaison à l'élément rigide doit se faire, si un autre élément de liaison est déjà fixé, en poussant ce dernier élément (fig. 4B). Lors de l'extension de l'assemblage, par exemple d'un bracelet (fig. 3), le tenon est bloqué par les butées 8' et 9' limitant respectivement le trou 4 et l'ouverture 7. Outre la simplicité du montage, l'assemblage objet de l'invention présente une grande facilité de démontage. Il suffit de pousser l'élément de liaison dans le même sens que lors du montage (fig. 4B, revendication 2). Le tenon glisse alors contre un épaulement 10 faisant face à la butée 8', de l'autre côté du trou 4. Dans le cas où le tenon estfixé à l'élément rigide (fig. 7), un tel épaulement peut être obtenu en insérant dans le tube formant le corps de l'élément de liaison une plaque présentant les échancrures nécessaires (trous 4) à l'introduction du tenon.The connection elements are joined together with the rigid elements very simply, by placing the connection element on the side of the cavity 3, in the same plane as the rigid element, and by pushing it into this cavity. During this introduction, the pin or pins meet the edge 8 of the rigid element (in case the pin is fixed to the connecting element, fig. 1 to 6), or the edge 8 of the connecting element (in case the post is fixed to the rigid element, fig. 7). The post, placed obliquely, gives way thanks to the bending of the elastic means 6 and disappears in the opening 7. When the end of the post is in front of the hole 4, it will become lodged in this hole under the effect the relaxation of the elastic means, that is to say, in the embodiments shown here, of the spring. In the embodiments of FIGS. 1 to 3, 5 to 9, the connecting elements are dimensioned so that they touch each other in the middle of the cavity 3. The fixing of a connecting element to the rigid element must be done, if another element of connection is already fixed, by pushing this last element (fig. 4B). When extending the assembly, for example a bracelet (fig. 3), the post is blocked by the stops 8 'and 9' respectively limiting the hole 4 and the opening 7. In addition to the simplicity of assembly , the assembly which is the subject of the invention has great ease of dismantling. It is enough to push the connecting element in the same direction as during assembly (fig. 4B, claim 2). The post then slides against a shoulder 10 facing the stop 8 ', on the other side of the hole 4. In the case where the post is fixed to the rigid element (fig. 7), such a shoulder can be obtained by inserting into the tube forming the body of the connecting element a plate having the necessary notches (holes 4) for the introduction of the post.

Afin d'assurer une souplesse suffisante à l'assemblage, il est préférable de donner au trou 4 et/ou à l'ouverture 7, dans l'épaisseur de l'élément rigide et/ou de l'élément de liaison, une dimension légèrement supérieure à celle du tenon: cela permet un certain débattement du tenon par rapport à l'élément rigide et/ou à l'élément de liaison. Un autre moyen d'assurer cette souplesse de l'assemblage, et qui peut être combiné avec le précédent, consiste à donner à l'élément de liaison une certaine courbure. Des éléments de liaison présentant une telle courbure sont représentés dans les fig. 8 et 9 qui montrent la combinaison d'éléments de liaison courbes et de trous 4 surdimensionnés dans l'épaisseur des éléments rigides.In order to ensure sufficient flexibility for assembly, it is preferable to give the hole 4 and / or the opening 7, in the thickness of the rigid element and / or the connecting element, a dimension slightly greater than that of the post: this allows a certain amount of travel of the post relative to the rigid element and / or to the connecting element. Another means of ensuring this flexibility of the assembly, and which can be combined with the previous one, consists in giving the connecting element a certain curvature. Connecting elements having such a curvature are shown in FIGS. 8 and 9 which show the combination of curved connecting elements and holes 4 oversized in the thickness of the rigid elements.

L'élément rigide peut être construit de diverses manières. Par exemple, il peut être taillé, par fraisage et perçage, ou partiellement étiré. Une autre possibilité consiste à découper plusieurs plaques, de façon appropriée, pour les souder ensuite l'un à l'autre. Enfin, il existe diverses possibilités de réaliser cet élément par pliage. S'il est fait d'un élément massif, les trous 4 peuvent avantageusement être pratiqués avec un poinçon de forme appropriée sur un marteau pneumatique.The rigid element can be constructed in various ways. For example, it can be cut, by milling and drilling, or partially stretched. Another possibility is to cut several plates, appropriately, and then weld them to each other. Finally, there are various possibilities of making this element by folding. If it is made of a solid element, the holes 4 can advantageously be made with an appropriately shaped punch on a pneumatic hammer.

Les deux éléments rigides du haut de la figure se touchent et sont par conséquent dans la position correspondant à celle de l'assemblage au repos, tandis que l'élément rigide du bas est éloigné au maximum de l'élément précédent, ce qui correspond à l'extention maximale de l'assemblage: les ressorts 6 sont tendus et les tenons butent contre les butées 8' et 9'.Fig. 3 is a plan view, in the same embodiment, of three rigid elements interconnected by two connecting elements. The two rigid elements at the top of the figure touch each other and are therefore in the position corresponding to that of the assembly at rest, while the rigid element at the bottom is as far as possible from the previous element, which corresponds to the maximum extension of the assembly: the springs 6 are tensioned and the pins abut against the stops 8 'and 9'.

La fig. 4 est une vue en plan d'un ressort selon les revendications 9 et 20, d'une forme particulièrement favorable et esthétique.Fig. 4 is a plan view of a spring according to claims 9 and 20, of a particularly favorable and aesthetic form.

En A, l'élément de liaison est poussé en direction de la flèche. Deux tenons 5, sous la pression du bord 8, se sont partiellement effacés dans le corps de l'élément de liaison. En B, l'élément de liaison a été poussé à fond: les tenons, sous la pression de l'épaulement 10, s'effacent de nouveau et sortent des trous 4, ce qui permet d'extraire l'élément de liaison. On voit en B comment l'élément de liaison poussé à fond pousse lui-même l'élément de liaison qui lui est adjacent.Fig. 5 is a plan view, in the same embodiment, of the phases of introduction and extraction of the connecting element in and of the rigid element. At A, the connecting element is pushed in the direction of the arrow. Two pins 5, under the pressure of the edge 8, have partially disappeared in the body of the connecting element. At B, the connecting element has been pushed all the way: the studs, under the pressure of the shoulder 10, are erased again and come out of the holes 4, which makes it possible to extract the connecting element. We see in B how the connecting element pushed to the bottom pushes itself the connecting element which is adjacent to it.

La fig. 6 est une vue en plan de deux formes d'exécution particulières. A gauche, l'élément de liaison comprend seulement deux tenons qui sont les deux extrémités d'un ressort en forme de S. A droite, l'élément de liaison est fixé à l'un des éléments rigides par une barrette, et à l'autre par un seul tenon.Fig. 6 is a plan view of two particular embodiments. On the left, the connecting element comprises only two pins which are the two ends of an S-shaped spring. On the right, the connecting element is fixed to one of the rigid elements by a bar, and to the other by a single stud.

La fig. 7 montre en plan une forme d'exécution dans laquelle les tenons, qui sont, comme dans les autres dessins, les deux extrémités d'un ressort, sont fixés par paires dans les parois latérales de la cavité. Les ressorts 6 présentent ici une boucle en leur centre. Une plaquette est insérée dans l'élément de liaison, dans laquelle est taillé l'épaulement 10 qui permet l'extraction de l'élément de liaison.Fig. 7 shows in plan an embodiment in which the tenons, which are, as in the other drawings, the two ends of a spring, are fixed in pairs in the side walls of the cavity. The springs 6 here have a loop in their center. A plate is inserted in the connecting element, in which is cut the shoulder 10 which allows the extraction of the connecting element.

La fig. 8 est une coupe longitudinale de quelques éléments d'un bracelet muni d'éléments de liaison courbes.Fig. 8 is a longitudinal section of some elements of a bracelet provided with curved connecting elements.

La fig. 9 est une coupe identique, dans laquelle la cavité 3 est recouverte d'une plaque 13.Fig. 9 is an identical section, in which the cavity 3 is covered with a plate 13.

La fig. 10 montre deux ressorts selon la revendication 21, les tenons étant reliés deux a deux.Fig. 10 shows two springs according to claim 21, the tenons being connected in pairs.

La fig. 11 montre les deux ressorts de la fig. 10 introduits dans le tube formant l'élément de liaison. Les deux ressorts sont pressés l'un contre l'autre, même lorsque l'assemblage est au repos, en raison des dimensions du tube. C'est un moyen de serrer ensemble plus fortement les éléments rigides.Fig. 11 shows the two springs of FIG. 10 introduced into the tube forming the connecting element. The two springs are pressed against each other, even when the assembly is at rest, due to the dimensions of the tube. It is a way to tighten the rigid elements more tightly.
