Description

La fermeture d'un bracelet de cuir ou en matière synthétique, notamment pour les montres-bracelet, se fait généralement à l'aide d'une boucle et d'un ardillon fixés à un premier brin du bracelet, l'ardillon étant introduit dans un trou fait dans le second brin du bracelet. Ce dispositif de fermeture absolument conventionnel est généralement complété de un ou deux passants chargés de maintenir l'extrémité libre du second brin de bracelet.The closure of a leather or synthetic strap, in particular for wristwatches, is generally done using a buckle and a barb fixed to a first strand of the bracelet, the barb being introduced into a hole made in the second strand of the bracelet. This absolutely conventional closing device is generally supplemented with one or two passers-by responsible for maintaining the free end of the second bracelet strand.

Un dispositif de fermeture selon cet art antérieur comporte de nombreux inconvénients: tout d'abord à la fabrication, les brins de bracelet n'étant pas identiques, les deux brins de bracelet doivent être fabriqués séparément, ce qui, dans le cas des bracelets en matière synthétiques, nécessite la confection de deux moules distincts, et de deux découpoirs distincts dans le cas de bracelets en cuir; d'autre part, il est nécessaire de fixer le ou les passants ainsi que la boucle et l'ardillon sur l'un des brins de bracelet, ce qui est une opération relativement coûteuse; ensuite à l'emploi ce système comporte aussi quelques inconvénients, dont en particulier celui de nécessiter un pliage important d'un brin de bracelet pour y introduire ou en sortir l'ardillon, ce qui à terme provoque une usure et une détérioration dudit brin de bracelet, de plus, au cas où la montre-bracelet est fixée autour d'un petit poignet, il reste une longueur libre de bracelet importante, ce qui diminue l'esthétique dudit bracelet.A closure device according to this prior art has many drawbacks: first of all during manufacture, the bracelet strands not being identical, the two bracelet strands must be manufactured separately, which, in the case of bracelets made of synthetic material, requires two separate molds, and two separate cutters in the case of leather bracelets; on the other hand, it is necessary to fix the passers-by as well as the buckle and the barb on one of the bracelet strands, which is a relatively expensive operation; then in use this system also has some drawbacks, including in particular that of requiring a significant folding of a strand of bracelet to introduce or leave the barb therein, which in the long term causes wear and deterioration of said strand. bracelet, moreover, in case the wristwatch is fixed around a small wrist, there remains a significant free length of bracelet, which decreases the aesthetics of said bracelet.

Le dispositif de fermeture d'un bracelet selon l'invention se propose d'éliminer les inconvénients mentionnés du dispositif selon l'art antérieur, soit de simplifier la fabrication des brins de bracelet en prévoyant deux brins de bracelet absolument identiques, en prévoyant un dispositif ne nécessitant qu'un minimum de pièces qu'il n'est pas nécessaire de fixer à l'un des brins par une opération coûteuse, ce qui conduit à une diminution sensible du coût de production et qui lors de l'emploi permet tout d'abord un réglage de longueur précis et une fermeture fiable, sans usure ou détérioration de l'un quelconque de ses constituants. Il est évident que pour avoir du succès, ce dispositif de fermeture doit être esthétique.The device for closing a bracelet according to the invention proposes to eliminate the mentioned drawbacks of the device according to the prior art, namely to simplify the manufacture of the bracelet strands by providing two absolutely identical bracelet strands, by providing a device requiring only a minimum of parts which it is not necessary to fix to one of the strands by an expensive operation, which leads to a significant reduction in the cost of production and which during use first of all allows precise length adjustment and reliable closure, without wear or deterioration of any of its constituents. It is obvious that to be successful, this closure device must be aesthetic.

Afin de répondre à ces exigences, le dispositif de fermeture selon l'invention possède les caractéristiques mentionnées dans la partie caractérisante des revendications.In order to meet these requirements, the closure device according to the invention has the characteristics mentioned in the characterizing part of the claims.

Le principe et le fonctionnement du dispositif de fermeture selon l'invention sont plus particulièrement compréhensibles à partir du dessin en annexe avec les figures où:

  • la figure 1 représente une vue en perspective de la première pièce du système,
  • la figure 2 représente une vue en pespective de la seconde pièce du système, selon une première forme d'exécution,
  • la figure 3 représente une coupe longitudinale d'un système de fermeture monté sur deux brins de bracelet,
  • la figure 4 représente une vue en plan par dessus du système précédent,
  • la figure 5 représente une vue en plan par dessus d'un système de fermeture selon une autre forme d'exécution, et
  • la figure 6 représente une vue en plan par dessous du système de fermeture selon la forme d'exécution de la figure 5,
  • la figure 7 représente une vue en perspective de la seconde pièce du système selon encore une autre forme d'exécution, et
  • la figure 8 représente une vue en perspective de la seconde pièce du système selon encore une autre forme d'exécution.
The principle and operation of the closure device according to the invention are more particularly understandable from the attached drawing with the figures where:
  • FIG. 1 represents a perspective view of the first part of the system,
  • FIG. 2 represents a perspective view of the second part of the system, according to a first embodiment,
  • FIG. 3 represents a longitudinal section of a closure system mounted on two strands of bracelet,
  • FIG. 4 represents a plan view from above of the previous system,
  • FIG. 5 represents a plan view from above of a closure system according to another embodiment, and
  • FIG. 6 represents a plan view from below of the closure system according to the embodiment of FIG. 5,
  • FIG. 7 represents a view in perspective of the second part of the system according to yet another embodiment, and
  • Figure 8 shows a perspective view of the second part of the system according to yet another embodiment.

A la figure 1 on a une vue en perspective de la première pièce 1 constituant le système de fermeture selon l'invention. Cette pièce 1 est constituée d'une plaque de base plane 10, représentée ici de forme ovale, mais pouvant être de n'importe quelle forme convenable. Sur cette plaque de base 10, on a deux tenons cylindriques 11 et 12 qui y sont fixés d'une manière quelconque, adaptée au mode de fabrication et au matériau utilisé pour ladite première pièce, de façon à être disposés perpendiculairement à la plaque 10, l'espacement entre les deux tenons correspondant à l'espacement entre les trous du bracelet dans lesquels ces tenons seront introduits. Selon cette forme d'exécution, l'un des tenons est plus long que l'autre, comme expliqué plus loin. Chacun de ces tenons 11 et 12 comporte un léger renflement en forme de collerette transversale, respectivement 11A et 12A, et dont le diamètre extérieur est très légèrement supérieur à celui du tenon. La fonction et la position axiale de ces collerettes seront expliquées plus loin. Le sommet de chaque tenon est représenté ici comme étant de forme hémisphérique, mais pourrait tout aussi bien être plat ou en pointe.In Figure 1 there is a perspective view of the first part 1 constituting the closure system according to the invention. This part 1 consists of a flat base plate 10, shown here in oval shape, but which can be of any suitable shape. On this base plate 10, there are two cylindrical tenons 11 and 12 which are fixed therein in any way, adapted to the manufacturing method and to the material used for said first part, so as to be arranged perpendicular to the plate 10, the spacing between the two studs corresponding to the spacing between the holes of the bracelet into which these studs will be introduced. According to this embodiment, one of the studs is longer than the other, as explained below. Each of these tenons 11 and 12 has a slight bulge in the form of a transverse collar, respectively 11A and 12A, and the outside diameter of which is very slightly greater than that of the tenon. The function and the axial position of these flanges will be explained later. The top of each post is shown here as being hemispherical, but could just as well be flat or pointed.

La figure 2 montre, une vue en perspective de la seconde pièce 2 constituant le système de fermeture selon l'invention. Cette pièce 2 est en forme de tube, de section rectangulaire dont le petit côté intérieur est très légèrement supérieur à l'épaisseur des deux brins de bracelet superposés et dont le grand côté intérieur est très légèrement supérieur à la largeur des brins de bracelet, afin que lorsque cette seconde pièce 2 est en place, elle puisse coulisser librement par dessus deux brins de bracelet superposés. La face supérieure 20 de ladite pièce 2 est pourvue d'une fente longitudinale 21 séparant la face supérieur 20 en deux lèvres 20A et 20B susceptibles de s'écarter légèrement, le corps de la pièce 2 faisant office de ressort. Une amorce 22 est disposée au début de la fente et une encoche circulaire 23 est disposée environ à mi-longueur de la fente. L'amorce 22 a une forme et des dimensions convenables afin que lorsqu'on y introduit perpendiculairement le tenon 12 de la pièce 1, les deux lèvres 20A et 20B s'écartent afin de laisser le passage audit tenon et que celui-ci puisse être glissé le long de la fente jusqu'à l'encoche circulaire 23, qui a le même diamètre que le tenon 12, et qu'il y reste pincé, les deux lèvres 20A et 20B se resserrant par effet de ressort de la pièce 2. La face inférieure 24 de la pièce 2 comporte une autre encoche 25, ayant une forme adaptée pour recevoir une partie de la plaque de base 10 de la pièce 1 lorsque les deux pièces sont connectées. Vu que la face inférieure 24 est affaiblie par la présence de l'encoche 25, sa largeur peut être légèrement augmentée, comme représenté en 24A, afin que la solidité de la pièce 2 soit garantie.Figure 2 shows a perspective view of the second part 2 constituting the closure system according to the invention. This part 2 is in the form of a tube, of rectangular section, the small inner side of which is very slightly greater than the thickness of the two overlapping bracelet strands and the large inner side of which is very slightly greater than the width. bracelet strands, so that when this second part 2 is in place, it can slide freely over two superimposed bracelet strands. The upper face 20 of said part 2 is provided with a longitudinal slot 21 separating the upper face 20 into two lips 20A and 20B capable of slightly deviating, the body of the part 2 acting as a spring. A primer 22 is disposed at the start of the slot and a circular notch 23 is disposed approximately halfway along the slot. The primer 22 has a suitable shape and dimensions so that when the stud 12 of the piece 1 is introduced perpendicularly therein, the two lips 20A and 20B move apart in order to allow passage to the said stud and so that it can be slid along the slot to the circular notch 23, which has the same diameter as the post 12, and remains pinched there, the two lips 20A and 20B tightening by the spring effect of the part 2. The lower face 24 of the part 2 has another notch 25, having a shape adapted to receive a part of the base plate 10 of the part 1 when the two parts are connected. Since the lower face 24 is weakened by the presence of the notch 25, its width can be slightly increased, as shown in 24A, so that the solidity of the part 2 is guaranteed.

Le système de fixation complet de la figure 3 montre la pièce 1 et la pièce 2 venant fixer deux brins de bracelet 30 et 31 superposés. Chacun de ces brins de bracelet comporte, sur son axe longitudinal, une série de trous 32, 33, traversants et équidistants. Tout d'abord on glisse la pièce 2 sur le brin de bracelet 31, la face 20 étant par dessus et l'amorce 22 tournée vers l'extrémité du brin 31, puis dans deux des trous 33, qui peuvent être successifs ou comporter un ou plusieurs trous intermédiaires, (dans le cas représenté, on a un trou intermédiaire) du brin inférieur 31, on introduit les tenons 11 et 12 de la pièce 1, en pressant sur la plaque de base 10; en appuyant fermement sur ladite plaque de base 10, on fait pénétrer en les forçant les collerettes 11A et 12A à travers les trous 33 du brin inférieur 31, jusqu'à ce qu'elles les aient traversés et qu'elles maintiennent fermement ladite pièce 1 au brin de bracelet inférieur 31; on voit donc que la distance séparant la face supérieure de la plaque de base 10 aux collerettes 11A et 12A doit être égale à l'épaisseur du brin de bracelet 31. Ensuite le brin de bracelet supérieur 30 est disposé par dessus le brin inférieur 31, les parties supérieures des tenons 11 et 12 étant introduites dans deux des trous 32 de ce brin 30, de façon à ce que le bracelet ait la longueur désirée. Il suffit ensuite de glisser la pièce 2 en direction du tenon 12, de faire pénétrer l'extrémité de ce tenon dans l'amorce 22, puis dans la fente 21 et finalement de venir verrouiller la pièce 1 dans la pièce 2 lorsque le tenon 12 est pincé dans l'encoche circulaire 23. On voit donc que la longueur du tenon 11 doit être telle que le sommet dudit tenon ne dépasse pas de la face supérieure du brin 30, alors que la longueur du tenon 12 doit être telle que ledit tenon dépasse ladite face supérieure afin qu'il puisse être pincé par la pièce 2.The complete fixing system of FIG. 3 shows the part 1 and the part 2 coming to fix two strands of bracelet 30 and 31 superimposed. Each of these bracelet strands has, on its longitudinal axis, a series of holes 32, 33, through and equidistant. First we slide the part 2 on the bracelet strand 31, the face 20 being above and the primer 22 facing the end of the strand 31, then in two of the holes 33, which may be successive or include a or several intermediate holes, (in the case shown, there is an intermediate hole) of the lower strand 31, the pins 11 and 12 of the part 1 are introduced, by pressing on the base plate 10; by pressing firmly on said base plate 10, the collars 11A and 12A are made to penetrate through the holes 33 of the lower strand 31, until they have passed through them and they firmly hold said part 1 to the lower bracelet strand 31; it can therefore be seen that the distance separating the upper face of the base plate 10 from the flanges 11A and 12A must be equal to the thickness of the bracelet strand 31. Then the upper bracelet strand 30 is placed over the lower strand 31, the upper parts of the tenons 11 and 12 being introduced into two of the holes 32 of this strand 30, so that the bracelet has the desired length. It then suffices to slide the part 2 in the direction of the tenon 12, to make the end of this tenon penetrate into the primer 22, then into the slot 21 and finally to come and lock the part 1 in the part 2 when the tenon 12 is pinched in the circular notch 23. It can therefore be seen that the length of the tenon 11 must be such that the top of said tenon does not protrude from the upper face of the strand 30, while the length of the tenon 12 must be such that said tenon protrudes from said upper face so that it can be pinched by part 2.

La figure 4 est une vue par dessus du système de la figure précédente, montrant bien comment le tenon 12 est engagé dans l'encoche 23.FIG. 4 is a view from above of the system of the previous figure, clearly showing how the tenon 12 is engaged in the notch 23.

Diverses variantes de cette première forme d'exécution peuvent être décrites: en particulier, si la plaque de base 10 de la pièce 1 est suffisamment mince, il n'est pas absolument nécessaire de prévoir l'encoche 25 sur la face 24 de la pièce 2, cette face 24 venant se superposer à la plaque de base 10; dans ce cas le prolongement 24A n'est pas non plus nécessaire. Une autre variante peut consister à prévoir une pièce 2 légèrement plus longue et dont la fente 21 comprend deux encoches circulaires 23 afin de venir pincer les deux tenons 11 et 12 qui sont alors de même longueur et dépassent de la surface supérieure du brin 30. De plus, le dispositif selon l'invention a été décrit avec deux tenons introduits dans deux trous de chaque brin de bracelet; il pourrait tout aussi bien fonctionner avec un seul ou plus de deux tenons, introduits dans le ou les trous correspondants des brins du bracelet.Various variants of this first embodiment can be described: in particular, if the base plate 10 of the part 1 is sufficiently thin, it is not absolutely necessary to provide the notch 25 on the face 24 of the part 2, this face 24 coming to be superimposed on the base plate 10; in this the extension 24A is also not necessary. Another variant may consist in providing a slightly longer part 2, the slot 21 of which comprises two circular notches 23 in order to pinch the two tenons 11 and 12 which are then of the same length and protrude from the upper surface of the strand 30. From more, the device according to the invention has been described with two pins inserted into two holes of each strand of bracelet; it could just as well work with a single or more than two studs, introduced into the corresponding hole or holes of the strands of the bracelet.

Aux figures 5 et 6 on a respectivement une vue de dessus et une vue de dessous d'une deuxième forme d'exécution d'un système de fixation selon l'invention. Dans ce cas, la plaque de base 10 est de forme longiligne et comporte un ou plusieurs renflements 13 pouvant être situés en n'importe quel endroit de ladite plaque 10, par exemple aux deux extrémités comme représenté sur la figure 6; un seul renflement situé au milieu de la longueur de la plaque 10 conviendrait tout aussi bien. Dans ce cas, les deux tenons 11 et 12 sont de même longueur et ne dépassent pas la surface supérieure du brin supérieur 30. La face inférieure 24 de la pièce 2 comporte une fente 26 avec une amorce 27 et une encoche 28 pour y glisser le renflement 13 afin de verrouiller les deux pièces comme précédemment. Vu que la face supérieure 20 de la pièce 2, face qui est visible, ne comporte aucune fente, cette deuxième forme d'exécution du système selon l'invention est plus esthétique que la précédente.In Figures 5 and 6 there is respectively a top view and a bottom view of a second embodiment of a fastening system according to the invention. In this case, the base plate 10 is of elongated shape and comprises one or more bulges 13 which can be located anywhere in said plate 10, for example at the two ends as shown in FIG. 6; a single bulge located in the middle of the length of the plate 10 would be equally suitable. In this case, the two tenons 11 and 12 are the same length and do not exceed the upper surface of the upper strand 30. The lower face 24 of the part 2 has a slot 26 with a primer 27 and a notch 28 for sliding the bulge 13 in order to lock the two parts as before. Since the upper face 20 of the part 2, the face which is visible, has no slot, this second embodiment of the system according to the invention is more aesthetic than the previous one.

Une autre forme d'exécution de la pièce 2, est visible à la fig. 7, dérivée de la première forme d'exécution de la figure 2; dans ce cas, la fente longitudinale 21 n'est pas aménagée sur toute la largeur de la face supérieure de la pièce 2, mais seulement sur une portion de cette largeur, afin de ne pas trop affaiblir ladite pièce 2. Pour permettre l'introduction du tenon, deux fentes latérales 21A et 21B sont disposées parallèlement à la fente 21, de part et d'autre de ladite fente afin que les deux côtés de la fente centrale agissent comme des ressorts. Comme précédemment, la fente centrale 21 est munie d'une amorce 22 ainsi que d'une encoche 23.Another embodiment of the part 2 is visible in FIG. 7, derived from the first embodiment of Figure 2; in this case, the longitudinal slot 21 is not arranged over the entire width of the upper face of the part 2, but only over a portion of this width, so as not to weaken said part 2 too much. To allow the insertion of the post, two lateral slots 21A and 21B are arranged parallel to the slot 21, on either side of said slot so that the two sides of the central slot act as springs. As before, the central slot 21 is provided with a primer 22 as well as a notch 23.

La figure 8 montre encore une autre forme d'exécution de la pièce 2, aussi dérivée de la forme d'exécution de la figure 2; comme précédemment, la fente longitudinale 21 n'est aménagée que sur une portion de la largeur de la face supérieure de la pièce 2, une autre portion de fente 21C, perpendiculaire à la précédente et disposée à l'extrémité de la fente 21 opposée à celle comportant l'amorce 22, est aménagée sur une portion de la longueur de la face supérieure de la pièce 2.Figure 8 shows yet another embodiment of part 2, also derived from the embodiment of Figure 2; as before, the longitudinal slot 21 is only fitted over a portion of the width of the upper face of the part 2, another slot portion 21C, perpendicular to the previous one and disposed at the end of the slot 21 opposite to that comprising the primer 22, is arranged over a portion of the length of the upper face of the part 2.

Ainsi, le dispositif de fermeture d'un bracelet, notamment d'un bracelet de montre-bracelet, répond parfaitement aux exigences fixées; la fabrication des brins de bracelet est simplifiée dans la mesure où chacun des brins est absolument identique et peut être obtenu par le même moule ou le même découpoir, aucune opération d'assemblage coûteuse n'est nécessaire pour disposer le système de fixation sur le bracelet, d'autre part à l'emploi, il n'est pas nécessaire de replier l'un des brins autour de la fixation, ce qui amène à une usure et une détérioration dudit brin et, vu que le système de fixation selon l'invention peut être disposé en n'importe quel endroit du bracelet où les trous de chaque brin se superposent, il est très aisé de le disposer de manière à ce que le brin libre soit de longueur minimum, ce qui permet d'éliminer le ou les passants nécessaires avec le dispositif de fixation selon l'art antérieur. L'effet esthétique du système de fermeture selon l'invention est favorable, d'autant plus qu'il peut être fait en n'importe quel matériau présentant l'élasticité suffisante pour obtenir l'effet de ressort mentionné, par exemple des métaux simples ou précieux ou des matières synthétiques. Le dispositif de fermeture a été décrit s'appliquant à un bracelet de montre; il est bien entendu qu'il s'applique aussi parfaitement à la fermeture de toutes autres sortes de bracelet et plus généralement à la liaison de deux liens en forme de bandes, comme des courroies.Thus, the device for closing a bracelet, in particular a wristwatch bracelet, perfectly meets the requirements set; the manufacture of the bracelet strands is simplified insofar as each of the strands is absolutely identical and can be obtained by the same mold or the same cutter, no expensive assembly operation is necessary to arrange the fastening system on the bracelet , on the other hand in use, it is not necessary to fold one of the strands around the fixing, which leads to wear and deterioration of said strand and, since the fixing system according to invention can be placed anywhere on the bracelet where the holes of each strand overlap, it is very easy to arrange it so that the free strand is of minimum length, which makes it possible to eliminate the passers-by required with the fixing device according to prior art. The aesthetic effect of the closure system according to the invention is favorable, especially since it can be made of any material having sufficient elasticity to obtain the spring effect mentioned, for example simple metals or precious or synthetic materials. The closure device has been described applying to a watch strap; it is understood that it also applies perfectly to the closure of all other kinds of bracelet and more generally to the connection of two links in the form of bands, such as belts.
