Description

La présente invention est relative à un bracelet notamment pour bracelet-montre comportant une pluralité de maillons de forme aplatie du genre gourmette.The present invention relates to a bracelet in particular for a wristwatch comprising a plurality of flattened links of the curb type.

Les bracelets métalliques se présentent le plus souvent comme un assemblage de maillons plats placés côte à côte et articulés les uns à la suite des autres. Il s'agit généralement de plaquettes disposées parallèlement et liées les unes aux autres au moyen de barrettes formant charnières placées perpendiculairement à la direction longitudinale du bracelet. Cette façon de faire permet d'obtenir, si on le désire, un bracelet à largeur décroissante présentant un profil agréable en assemblant entre eux des maillons à largeur elle-même décroissante. Une telle construction permet aussi une bonne flexibilité en même temps qu'un ébat latéral quasi inexistant d'un maillon par rapport au maillon voisin. Cependant, ce genre de bracelet présente un aspect particulièrement monotone mis en évidence surtout par la répétition de maillons à surface plate.Metal bracelets are most often presented as an assembly of flat links placed side by side and articulated one after the other. They are generally plates arranged in parallel and linked to each other by means of bars forming hinges placed perpendicular to the longitudinal direction of the bracelet. This procedure makes it possible to obtain, if desired, a decreasing width bracelet having a pleasant profile by assembling between them links with decreasing width itself. Such a construction also allows good flexibility at the same time as an almost nonexistent side flap of a link relative to the neighboring link. However, this kind of bracelet has a particularly monotonous appearance, highlighted above all by the repetition of links with flat surfaces.

Pour donner au bracelet un aspect plus esthétique, tout en proposant encore des maillons à surface plate, on peut utiliser un bracelet de type gourmette. Il s'agit là d'un bracelet formé de maillons entrelacés et plus ou moins serrés comme il en est fait usage pour les chaînes de montre de poche. Dans ce cas, les anneaux couchés les uns sur les autres donnent au bracelet une ligne ondulée du plus bel effet. Cependant, la chaîne gourmette présente l'inconvénient que les anneaux dont elle est composée doivent être soudés une fois insérés les uns dans les autres, ce qui ne va pas de soi quand on utilise certains matériaux comme le titane difficilement soudable mais présentant toutefois à côté de sa légèreté une résistance à l'usure remarquable. Il faut noter aussi que la gourmette classique présente des anneaux qui se déplacent latéralement l'un par rapport à l'autre, ce qui a pour effet de permettre un enroulement de la gourmette sur elle-même dans son sens longitudinal. Cet effet n'est pas souhaité pour un bracelet de montre.To give the bracelet a more aesthetic appearance, while still offering links with a flat surface, a bracelet of the curb type can be used. This is a bracelet made up of intertwined links that are more or less tight as it is used for pocket watch chains. In this case, the rings lying on top of each other give the bracelet a wavy line with the most beautiful effect. However, the curb chain has the disadvantage that the rings of which it is composed must be welded once inserted into each other, which is not obvious when using certain materials such as titanium which is difficult to weld but which nevertheless has next to it of its lightness a remarkable resistance to wear. It should also be noted that the conventional curb chain has rings which move laterally with respect to one another, which has the effect of allowing the curb chain to be wound on itself in its longitudinal direction. This effect is not desired for a watch strap.

La présente invention a pour but de proposer un bracelet ayant l'aspect d'une gourmette sans présenter les inconvénients cités plus haut. Pour cela, il est pourvu des moyens qui apparaissent dans les revendications, moyens qui vont être expliqués maintenant à l'aide de la description qui suit, illustrée à titre d'exemple par les dessins dans lesquels :

  • Les figures 1a et 1b présentent un maillon du bracelet selon l'invention, vu de dessus et de dessous, respectivement.
  • La figure 2 montre un segment de bracelet partiellement monté et vu de dessous.
  • La figure 3 montre un demi-bracelet, vu de dessous, auquel est attaché d'un côté une montre et de l'autre côté un dispositif de fermeture.
The present invention aims to provide a bracelet having the appearance of a curb without having the drawbacks mentioned above. For this, it is provided with the means which appear in the claims, means which will now be explained with the aid of the description which follows, illustrated by way of example in the drawings in which:
  • Figures 1a and 1b show a link of the bracelet according to the invention, seen from above and from below, respectively.
  • Figure 2 shows a partially mounted bracelet segment seen from below.
  • Figure 3 shows a half bracelet, seen from below, to which is attached on one side a watch and on the other side a closure device.

Le maillon 1 de la figure 1a présente un contour elliptique 5 où le grand axe 3 de l'ellipse s'étend dans la direction longitudinale du bracelet. On pratique au centre du maillon 1 une ouverture 2 en forme de losange dont la diagonale principale coïncide avec le grand axe 3 de l'ellipse. Un premier canal 30 s'étendant obliquement d'un bord 8 à l'autre 8' du maillon est creusé dans son épaisseur du côté de sa face supérieure. Les bords de ce canal 30 passent par les deux premiers côtés opposés 4 et 4' de l'ouverture 2 en forme de losange. Ainsi, vu de dessus le maillon 1 présente deux parties surélevées proéminentes 6 et 6' séparées par le canal 30. Les parties 6 et 6' peuvent avoir une surface supérieure plate mais présentent, dans une version préférée de l'invention, une calotte arrondie ou ellipsoïdale. Une fente 9 est pratiquée dans l'épaisseur du maillon et disposée le long du canal 30 entre l'ouverture 2 en forme de losange et le bord 8 du maillon. Par cette fente, on pourra introduire un second maillon dans le premier.The link 1 of Figure 1a has an elliptical outline 5 where the major axis 3 of the ellipse extends in the longitudinal direction of the bracelet. An opening 2 in the form of a diamond is made at the center of the link 1, the main diagonal of which coincides with the major axis 3 of the ellipse. A first channel 30 extending obliquely from one edge 8 to the other 8 ′ of the link is hollowed out in its thickness on the side of its upper face. The edges of this channel 30 pass through the two first opposite sides 4 and 4 'of the diamond-shaped opening 2. Thus, seen from above the link 1 has two prominent raised parts 6 and 6 'separated by the channel 30. The parts 6 and 6' may have a flat upper surface but have, in a preferred version of the invention, a rounded cap or ellipsoidal. A slot 9 is made in the thickness of the link and disposed along the channel 30 between the diamond-shaped opening 2 and the edge 8 of the link. Through this slot, we can introduce a second link in the first.

La figure 1b représente le même maillon 1 vu de dessous et retourné à 180° par rapport à la vue de la figure 1a. Ici un second canal 31 s'étendant obliquement d'un bord 7 à l'autre 7' du maillon est creusé dans son épaisseur du côté de sa face inférieure. Les bords de ce canal passent par les deux seconds côtés opposés 32 et 32' de l'ouverture 2 en forme de losange. Vu de dessous, le maillon 1 présente également deux parties surélevées 33 et 33' séparées par le canal 31. Les parties 33 et 33' présentent de préférence une surface proéminente plate.FIG. 1b represents the same link 1 seen from below and turned 180 ° relative to the view in FIG. 1a. Here a second channel 31 extending obliquely from one edge 7 to the other 7 ′ of the link is hollowed out in its thickness on the side of its lower face. The edges of this channel pass through the two opposite second sides 32 and 32 'of the diamond-shaped opening 2. Seen from below, the link 1 also has two raised parts 33 and 33 'separated by the channel 31. The parts 33 and 33' preferably have a prominent flat surface.

Dans l'arrangement qui vient d'être décrit on comprend que si l'on introduit par sa tranche un second maillon dans un premier par la fente 9, qu'on rabat ensuite le second maillon de 90° par rapport au premier, la partie du canal 30 située vers le bord 8 du premier maillon viendra s'imbriquer dans la partie du canal 31 située vers le bord 7' du second maillon en même temps que la partie du canal 31 située vers le bord 7 du premier maillon viendra s'imbriquer dans la partie du canal 30 située vers le bord 8' du second maillon. En d'autres termes et vu de dessus, la partie surélevée 6' du second maillon va recouvrir la partie du canal 30 située vers le bord 8 du premier maillon, pendant que la partie surélevée 6 du premier maillon va recouvrir la partie du canal 30 située vers le bord 8' du second maillon. On obtient ainsi l'entrelacement de deux maillons et ainsi de suite si l'on introduit un troisième maillon dans le second, etc.In the arrangement which has just been described, it is understood that if a second link is inserted through its edge in a first one through the slot 9, then the second link is folded down by 90 ° relative to the first, the part of the channel 30 located towards the edge 8 of the first link will be nested in the part of the channel 31 located towards the edge 7 'of the second link at the same time as the part of the channel 31 located towards the edge 7 of the first link will come nest in the part of channel 30 located towards the edge 8 'of the second link. In other words and seen from above, the raised part 6 ′ of the second link will cover the part of the channel 30 located towards the edge 8 of the first link, while the raised part 6 of the first link will cover the part of the channel 30 located towards the edge 8 'of the second link. We thus obtain the interlacing of two links and so on if we introduce a third link in the second, etc.

Reste à pourvoir les maillons composant le bracelet de moyens permettant leur articulation réciproque sans lesquels les maillons ne resteraient pas à plat et s'enrouleraient les uns à la suite des autres. Pour cela et selon une construction préférée de l'invention, on pratique dans le maillon deux trous 10 et 11 le traversant de part en part par sa tranche comme on peut le voir dans les figures 1 a et 1 b. Les trous 10 et 11 sont percés selon les axes a et a, respectivement. Les premier et second trous 10 et 11 passent respectivement par les premier et second sommets de l'ouverture 2 en forme de losange par lesquels passe la diagonale principale 3, ces trous étant perpendiculaires à ladite diagonale. Quand deux maillons sont assemblés en cascade, l'axe a, du premier maillon coïncide avec l'axe a du second, ce qui permet d'introduire dans les trous respectifs ainsi alignés une barrette formant articulation.It remains to provide the links making up the bracelet with means allowing their reciprocal articulation without which the links would not remain flat and would roll up one after the other. For this and according to a preferred construction of the invention, two holes 10 and 11 are passed through the link through it right through by its edge as can be seen in FIGS. 1 a and 1 b. The holes 10 and 11 are drilled along the axes a and a, respectively. The first and second holes 10 and 11 pass respectively through the first and second vertices of the diamond-shaped opening 2 through which the main diagonal 3 passes, these holes being perpendicular to said diagonal. When two links are assembled in cascade, the axis a of the first link coincides with the axis a of the second, which makes it possible to introduce into the respective holes thus aligned a bar forming an articulation.

On s'arrange pour donner à chacune des parties du canal 30 une double déclivité se rejoignant en une arête émergeant du fond dudit canal et parallèle aux axes a et a, respectivement.Arrangements are made to give each of the parts of channel 30 a double slope which meets at an edge emerging from the bottom of said channel and parallel to axes a and a, respectively.

Pour sa part, le canal 31 possède un fond arqué dont la courbure est semblable à celle présentée par la face immédiatement supérieure 6, 6' du maillon de telle façon que le maillon présente à cet endroit une épaisseur réduite destinée en outre à passer par la fente 9 d'un autre maillon lors de l'assemblage du bracelet. On réalisera donc une fente 9 légèrement plus large que ladite épaisseur réduite.For its part, the channel 31 has an arcuate bottom whose curvature is similar to that presented by the immediately upper face 6, 6 ′ of the link so that the link has a reduced thickness at this location intended further to pass through the slot 9 of another link when assembling the bracelet. A slit 9 will therefore be produced slightly wider than said reduced thickness.

Le canal 30 d'un premier maillon coopère avec le canal 31 d'un second maillon et la réalisation respective de chacun de ces canaux telle qu'elle vient d'être décrite assure ainsi une mobilité angulaire d'un maillon par rapport à l'autre quand ils sont assemblés. On comprend que l'angle de manceuvre d'un maillon sur l'autre est celui de l'angle présenté par la double déclivité existant au fond du canal 30.The channel 30 of a first link cooperates with the channel 31 of a second link and the respective embodiment of each of these channels as just described thus ensures angular mobility of a link relative to the other when they are assembled. It is understood that the angle of operation of a link on the other is that of the angle presented by the double slope existing at the bottom of the channel 30.

La figure 2 montre un segment de bracelet partiellement monté et vu de dessous. Les quatre premiers maillons de droite ont été imbriqués les uns dans les autres. Les barrettes 12 n'ont pas encore été introduites dans les trous dont les axes sont désignés par a, à a4. Pour limiter au maximum l'ébat latéral, la figure montre, en position non montée, des entretoises 13. Les trois maillons de gauche sont montrés après la mise en place des barrettes 12 et des entretoises 13 placées sur le chemin des barrettes 12 et entre deux maillons.Figure 2 shows a partially mounted bracelet segment seen from below. The first four links on the right have been nested into each other. The bars 12 have not yet been introduced into the holes whose axes are designated by a, a a 4 . To limit the lateral clearance as much as possible, the figure shows, in the unassembled position, spacers 13. The three links on the left are shown after the positioning of the bars 12 and of the spacers 13 placed on the path of the bars 12 and between two links.

Il est à noter que les barrettes 12 peuvent être chassées dans leurs trous respectifs. Ce sera le cas surtout pour les maillons qui n'auront pas à être démontés, ceux situés par exemple du côté montre. Du côté fermoir cependant, il est souhaitable de pouvoir raccourcir ou rallonger le bracelet par la suppression ou l'adjonction d'un maillon respectivement. Dans ce cas, la barrette 12 comportera à son extrémité 40 une fente pour former une tête de vis et à son extrémité 41 un filetage qui viendra vissé dans un taraudage 42 pratiqué dans l'extrémité du trou porté par le dernier maillon et dont l'axe est désigné par a,.It should be noted that the bars 12 can be driven into their respective holes. This will be the case especially for the links which will not have to be dismantled, those located for example on the watch side. On the clasp side, however, it is desirable to be able to shorten or lengthen the bracelet by removing or adding a link respectively. In this case, the bar 12 will have at its end 40 a slot to form a screw head and at its end 41 a thread which will be screwed into a thread 42 made in the end of the hole carried by the last link and whose axis is designated by a ,.

La figure 3 montre à échelle agrandie un demi-bracelet vu de dessous auquel est attaché d'un côté une montre schématisée par sa carrure 43 et de l'autre côté un dispositif de fermeture présentant une boucle 44. Sur la carrure est soudé le premier maillon 27 (qui pourrait aussi être monté à articulation). La boucle de fermeture 44 est articulée sur le premier maillon 21. La figure 3 montre aussi que les trois premiers maillons 21, 22, 23 sont identiques alors que les trois derniers 24, 25, 26 présentent une surface croissante. Chacun des maillons présentés est semblable à celui discuté à propos de la figure 1b et l'on a porté pour le maillon 24 les mêmes références utilisées sur ladite figure 1 b.Figure 3 shows on an enlarged scale a half bracelet seen from below to which is attached on one side a watch shown schematically by its middle part 43 and on the other side a closure device having a buckle 44. On the middle part is welded the first link 27 (which could also be hinged). The closing loop 44 is articulated on the first link 21. FIG. 3 also shows that the first three links 21, 22, 23 are identical while the last three 24, 25, 26 have an increasing surface. Each of the links presented is similar to that discussed in connection with FIG. 1b and the same references used in said FIG. 1b have been given for link 24.

Si le bracelet montré en figure 3 est destiné à un bracelet-montre, il est clair qu'il pourrait être utilisé à d'autres fins, particulièrement à des articles de joaillerie comme des tours de bras ou des colliers. Dans le cas du collier cependant, on cherchera à obtenir non une ligne droite, comme un bracelet de montre, mais une ligne incurvée. Cet effet peut être obtenu en ménageant des trous selon des axes a2, a3, etc. qui sont convergents entre eux au lieu d'être parallèles comme le montre la figure 3.If the bracelet shown in FIG. 3 is intended for a watch bracelet, it is clear that it could be used for other purposes, particularly for articles of jewelry such as arm rings or necklaces. In the case of the necklace, however, we will seek to obtain not a straight line, like a watch strap, but a curved line. This effect can be obtained by providing holes along axes a 2 , a 3 , etc. which are converging with each other instead of being parallel as shown in Figure 3.

Ainsi, selon la description qui vient d'être donnée, on peut construire des bracelets du style gourmette à mailles plates dont les anneaux ne sont pas soudés mais qui présentent une bonne articulation tout en restant dans un plan sans présenter de déplacement latéral. On obtient ainsi une gourmette qui ne présente pas l'inconvénient de s'enrouler sur elle-même. Cette construction permet également de raccourcir ou d'allonger la gourmette sans avoir à sectionner ou à souder d'anneaux. La forme arrondie ou ellipsoïdale qu'on peut donner à la surface supérieure des anneaux augmente aussi la ressemblance que présente le bracelet objet de l'invention avec une gourmette classique. On notera aussi que la construction décrite présente une sûreté bien meilleure que celle proposée par un bracelet classique. En effet, si l'une des barrettes 12 vient à se rompre, les maillons ne pourront pas se détacher facilement puisqu'il faut faire passer la tranche d'un maillon dans la fente du maillon adjacent pour opérer cette séparation, ce qui ne peut se faire qu'en y portant une attention spéciale.Thus, according to the description which has just been given, it is possible to construct bracelets of the curb chain style with flat links whose rings are not welded but which have good articulation while remaining in a plane without exhibiting lateral displacement. This gives a curb chain which does not have the disadvantage of winding on itself. This construction also makes it possible to shorten or lengthen the curb without having to cut or weld rings. The rounded or ellipsoidal shape that can be given to the upper surface of the rings also increases the resemblance of the bracelet object of the invention with a classic curb chain. It will also be noted that the construction described presents a much better safety than that proposed by a conventional bracelet. Indeed, if one of the bars 12 breaks, the links will not be able to detach easily since it is necessary to pass the edge of a link through the slot of the adjacent link to effect this separation, which cannot only by paying special attention to it.

On dira pour terminer que les maillons peuvent être réalisés en toutes sortes de matériaux : en métal précieux ou non, en métal soudable ou non ou encore en matériau non métallique comme, par exemple, en fibre de carbone ou en matière plastique. Dans ces derniers cas, il sera possible de mouler le maillon en une seule opération.Finally, we will say that the links can be made of all kinds of materials: precious metal or not, weldable metal or not, or non-metallic material such as, for example, carbon fiber or plastic. In these latter cases, it will be possible to mold the link in a single operation.
