Abstract

The fastener for a wristwatch band comprises two hollow elements (1, 2) which are arched to follow the curve of the wrist and each fixed to the end (9, 13) of one of the standard-length sides of a band. The element (1) is twice as long as the element (2). The latter can slide freely in the element (1) on a shoulder (19) of the flanks of the latter. The element (2) is usually locked in the element (1) by a leaf spring (21) carrying a row of ratchet-teeth (24) in its front part and whose rear end (22) is fixed to the bottom of a channel (4). The front end of the leaf (21) is folded so as to form a gripping element. With the aid of conventional spring bars (10, 14), the ends (9, 13) of the sides of the band can be fixed more or less deeply into the elements (1, 2) of the fastener by engaging the bars (10, 14) in those of the pairs of holes (7, 11) made through the flanks of the elements (1, 2) which match the dimensions of the wristwatch-wearer's wrist. According to the diurnal variations in the dimensions of his wrist, the user can make a fine adjustment to the length of his band by raising the end (23) of the leaf (21) which releases the element (2), as if to open the band, and makes it possible to place it in the desired position. <IMAGE>

Description

Les fermoirs selon le préambule de la revendication 1, qui sont connus, ne permettent pas au porteur de la montre d'ajuster la longueur du bracelet dans le cas des bracelets métalliques. Celle-ci doit être effectuée en magasin, par le vendeur. Pour effectuer cette opération, ce dernier enlève un certain nombre d'éléments des brins du bracelet, qui deviennent inutilisables. Le fabricant de bracelets doit cependant prévoir des brins assez longs pour convenir aux poignets les plus gros. Comme la majorité des personnes ont toutefois un poignet plus petit que cette norme, il s'ensuit que le fabricant produit dans la majorité des cas un nombre inutilement élevé de maillons de bracelet, puisque plusieurs d'entre eux sont jetés par la suite. Comme le porteur de la montre ne peut plus modifier la longueur du bracelet par la suite, ce dernier risque fort de l'incommoder car, au cours d'une journée de travail, les poignets n'ont pas toujours la même dimension; ils tendent à gonfler vers le soir. Si le bracelet est bien ajusté le matin, il risque donc, le soir, de comprimer le poignet de façon désagréable, voire insupportable. Si, au contraire, c'est le soir que le bracelet est convenablement ajusté, il risque de laisser tourner la montre autour du poignet le matin.The clasps according to the preamble of claim 1, which are known, do not allow the wearer of the watch to adjust the length of the bracelet in the case of metal bracelets. This must be done in store by the seller. To carry out this operation, the latter removes a certain number of elements from the strands of the bracelet, which become unusable. The manufacturer of bracelets must however provide long enough strands to suit the larger wrists. Since the majority of people, however, have a wrist smaller than this standard, it follows that the manufacturer in the majority of cases produces an unnecessarily high number of bracelet links, since several of them are subsequently thrown away. As the wearer of the watch can no longer modify the length of the bracelet thereafter, the latter is likely to inconvenience him because, during a working day, the wrists do not always have the same size; they tend to swell around the evening. If the bracelet is properly adjusted in the morning, it may, in the evening, compress the wrist unpleasantly, even unbearably. If, on the other hand, it is in the evening that the bracelet is properly adjusted, it may allow the watch to turn around the wrist in the morning.

Ces derniers inconvénients sont moindres dans le cas des bracelets en cuir, en tissu ou en plastique, dont le fermoir est composé d'une boucle avec ardillon fixés à l'extrémité de l'un des brins du bracelet et d'une rangée de trous le long de l'autre brin. Toutefois, les espaces entre deux trous consécutifs sont souvent trop grands pour permettre un ajustement adéquat de la longueur du bracelet. De plus, il y a toujours une partie plus ou moins longue du brin qui passe à travers la boucle, au-delà de l'ardillon, qui est inutile et parfois même gênante, en raison de la surépaisseur qu'elle crée. Enfin, comme le brin de bracelet portant la boucle du fermoir a une longueur déterminée, cette boucle 'sera d'un côté du poignet chez les personnes ayant de gros bras, et de l'autre côté du poignet chez celles ayant de petits bras, lorsque la montre sera elle-même au milieu du poignet.These latter drawbacks are less in the case of leather, fabric or plastic bracelets, the clasp of which consists of a buckle with a pin fixed at the end of one of the strands of the bracelet and a row of holes along the other strand. However, the spaces between two consecutive holes are often too large to allow an adequate adjustment of the length of the bracelet. In addition, there is always a more or less long part of the strand which passes through the loop, beyond the barb, which is useless and sometimes even annoying, in because of the extra thickness it creates. Finally, as the strand of the bracelet carrying the buckle of the clasp has a determined length, this loop will be on one side of the wrist in people with large arms, and on the other side of the wrist in those with small arms, when the watch is itself in the middle of the wrist.

Un fermoir présentant les particularités définies par la caractéristique de la revendication 1 a l'avantage de permettre à son porteur de modifier très rapidement et aisément la longueur de son bracelet. Il lui suffit, en effet, de soulever l'organe élastique du fermoir pour en libérer l'élément intérieur et le faire coulisser hors de l'élément extérieur sur une distance correspondant au gonflement de son poignet. En relâchant alors le dit organe élastique, il bloque derechef l'élément intérieur du fermoir dans l'élément extérieur dans la nouvelle position. Par la même manoeuvre du dit organe élastique, il peut aussi ouvrir le bracelet. Il lui suffit de maintenir cet organe élastique écarté de l'élément intérieur du fermoir jusqu'à ce que ce dernier soit entièrement dégagé de l'élément extérieur. Si, au contraire, le bracelet est devenu momentanément trop grand, il suffit de pousser l'élément intérieur du fermoir un peu plus dans l'élément extérieur pour raccourcir le bracelet dans la mesure voulue. Les dents de loup de l'élément intérieur écartent, en effet, automatiquement l'organe élastique contenu dans l'élément extérieur quand l'élément intérieur est poussé dans celui-ci.A clasp having the features defined by the characteristic of claim 1 has the advantage of allowing its wearer to modify the length of its bracelet very quickly and easily. It suffices for him, in fact, to lift the elastic member of the clasp to release the inner element therefrom and make it slide out of the outer element over a distance corresponding to the swelling of his wrist. By then releasing said elastic member, it again blocks the inner element of the clasp in the outer element in the new position. By the same operation of said elastic member, it can also open the bracelet. It suffices to keep this elastic member away from the inner element of the clasp until the latter is entirely disengaged from the outer element. If, on the contrary, the bracelet has temporarily become too large, it suffices to push the inner element of the clasp a little more into the outer element to shorten the bracelet to the desired extent. The wolf teeth of the inner element, in fact, automatically separate the elastic member contained in the outer element when the inner element is pushed into it.

Les formes spéciales d'exécution selon la revendication 2 ont l'avantage supplémentaire de permettre au fabricant du bracelet de produire des brins de bracelet de longueur standard aussi bien dans le cas des bracelets métalliques que dans celui des bracelets en cuir, en tissu ou en plastique, ce qui lui permet de réaliser une économie importante. En effet, chez le 85% des hommes, par exemple, la différence entre le périmètre du poignet le plus petit et celui du poignet le plus grand n'est que de 28 mm. Or, avec un fermoir ayant une longueur de 3 à 3,5 cm, le bracelet peut être adapté à tout ces poignets. A cet effet, il suffit d'engager les barrettes de fixation des brins du bracelet dans des paires de trous des éléments du fermoir plus ou moins rapprochées du centre de ce dernier. De cette façon, les sections des deux brins du bracelet, qui s'étendent depuis le fermoir jusqu'à la montre, ont toujours la même longueur et le fermoir se trouve donc toujours au milieu du poignet quand la montre de l'autre côté est elle-même aussi au milieu du poignet. Ces formes spéciales d'exécution sont également avantageuses dans le cas des bracelets souples, en cuir, en tissu ou en plastique, car elles év- tent la superposition, sur un brin du bracelet d'un excédent de longueur de l'autre brin.The special embodiments according to claim 2 have the additional advantage of allowing the bracelet manufacturer to produce standard length bracelet strands in the case of metallic bracelets as well as in the case of leather, fabric or leather bracelets. plastic, which allows it to achieve significant savings. Indeed, in the 85% of men, for example, the difference between the perimeter of the smallest wrist and that of the largest wrist is only 28 mm. However, with a clasp having a length of 3 to 3.5 cm, the bracelet can be adapted to all these wrists. To this end, it suffices to engage the bars for fixing the strands of the bracelet in pairs of holes in the elements of the clasp more or less close to the center of the latter. In this way, the sections of the two strands of the bracelet, which extend from the clasp to the watch, always have the same length and the clasp is therefore always in the middle of the wrist when the watch on the other side is itself also in the middle of the wrist. These special embodiments are also advantageous in the case of flexible bracelets, of leather, fabric or plastic, because they avoid the superimposition, on one strand of the bracelet, of an excess of length of the other strand.

Les particularités du fermoir défini par la revendication 3 ont l'avantage de rendre plus aisée l'opération de fermeture du bracelet pour le porteur de la montre. Il ne doit pas, en effet, s'évertuer à faire entrer l'élément intérieur du fermoir dans l'autre en cherchant à l'y glisser, ce qui n'est pas aisé à faire d'une seule main; il lui suffit de placer les deux éléments du fermoir l'un au-dessus de l'autre, puis de les presser l'un contre l'autre pour fermer son bracelet.The features of the clasp defined by claim 3 have the advantage of making it easier to close the strap for the wearer of the watch. It must not, in fact, strive to bring the inner element of the clasp into the other by trying to slide it, which is not easy to do with one hand; it is enough for him to place the two elements of the clasp one above the other, then to press them one against the other to close his bracelet.

Enfin, les particularités définies par la revendication 4 ont l'avantage tout d'abord de permettre une réalisation très simple de l'organe élastique du fermoir, qui assure le verrouillage de ses deux éléments l'un dans l'autre, et aussi celui de conférer à l'emboutissage servant de logement au dit organe élastique une fonction décorative sur la face visible du fermoir.Finally, the features defined by claim 4 have the advantage first of all of allowing a very simple production of the elastic member of the clasp, which ensures the locking of its two elements one inside the other, and also that to give the stamping used to house said elastic member a decorative function on the visible face of the clasp.

Une forme d'exécution du fermoir selon l'invention est représentée schématiquement et à simple titre d'exemple au dessin, dans lequel:

  • la Fig. 1 en est une vue en perspective éclatée;
  • la Fig. 2 une coupe longitudinale, selon le plan médian du fermoir;
  • la Fig. 3 une section transversale selon la ligne III-III de la Fig. 2, les deux éléments du fermoir étant dans la position qu'ils occupent immédiatement avant la fermeture du bracelet,
  • la Fig. 4 une section transversale semblable à celle de la Fig. 3, les deux éléments du fermoir étant en position fermée.
An embodiment of the clasp according to the invention is shown schematically and simply by way of example in the drawing, in which:
  • Fig. 1 is an exploded perspective view;
  • Fig. 2 a longitudinal section, along the median plane of the clasp;
  • Fig. 3 a cross section along line III-III of FIG. 2, the two elements of the clasp being in the position they occupy immediately before the bracelet is closed,
  • Fig. 4 a cross section similar to that of FIG. 3, the two elements of the clasp being in the closed position.

Le fermoir représenté au dessin comprend deux éléments 1, 2, courbés en arc de cercle (Fig. 2) pour épouser au mieux la forme du poignet. La longueur de l'élément 1 est, au moins approximativement, égale au double de celle de l'élément 2. Le profil de ces éléments a la forme générale d'un rectangle. Les éléments 1. 2 sont creux. La paroi supérieure 3 de l'élément 1 est emboutie de façon à présenter un canal longitudinal 4 à l'intérieur et une saillie médiane 5 à l'extérieur (Fig. 3 et 4). Les dimensions de cet élément 1 sont ajustées à celles de l'élément 2 de façon que ce dernier puisse coulisser librement dans l'élément 1. Dans la partie médiane de sa face supérieure et sur une largeur légèrement inférieure à celle du canal 4, l'élément 2 présente une rangée de dents de loup 6 s'étendant depuis son extrémité entrant dans l'élément 1 jusqu'à quelque distance de son autre extrémité (Fig. 1).The clasp shown in the drawing includes two elements 1, 2, curved in an arc of a circle (Fig. 2) to best fit the shape of the wrist. The length of element 1 is, at least approximately, equal to twice that of element 2. The profile of these elements has the general shape of a rectangle. Elements 1. 2 are hollow. The upper wall 3 of the element 1 is stamped so as to present a longitudinal channel 4 on the inside and a median projection 5 on the outside (Fig. 3 and 4). The dimensions of this element 1 are adjusted to those of the element 2 so that the latter can slide freely in the element 1. In the middle part of its upper face and over a width slightly less than that of the channel 4, l element 2 has a row of wolf teeth 6 extending from its end entering element 1 to some distance from its other end (Fig. 1).

Une rangée de paires équidistantes de trous 7 est .percée à travers les flancs 8 de l'élément 2, sur toute la longueur de ce dernier. L'extrémité 9 d'un brin de bracelet, de largeur égale à celle de l'ouverture de l'élément 2, peut ainsi être fixée à cet élément à l'aide d'une barrette à ressort - représentée schématiquement en 10 et identique à elles utilisées pour fixer le bracelet à la boîte de montre - simplement en engageant les tétons formés aux extrémités de cette barrette dans n'importe laquelle des paires de trous 7.A row of equidistant pairs of holes 7 is drilled through the flanks 8 of the element 2, over the entire length of the latter. The end 9 of a bracelet strand, of width equal to that of the opening of the element 2, can thus be fixed to this element using a spring bar - shown schematically at 10 and identical used to attach the strap to the watch case - simply by engaging the pins formed at the ends of this bar in any of the pairs of holes 7.

Des paires de trous 11 sont, de même, percées à travers les flancs 12 de l'élément 1, toutefois uniquement sur la moitié de sa longueur, depuis son extrémité opposée à celle recevant l'élément 2. Comme l'extrémité 9, l'extrémité 13 de l'autre brin du bracelet peut être engagée plus ou moins profondément dans l'élément 1 et fixée à ce dernier dans la position voulue à l'aide d'une barrette 14, identique à la barrette 10.Pairs of holes 11 are likewise drilled through the flanks 12 of the element 1, however only over half of its length, from its end opposite to that receiving the element 2. Like the end 9, l the end 13 of the other strand of the bracelet can be engaged more or less deeply in the element 1 and fixed to the latter in the desired position using a bar 14, identical to the bar 10.

Les trous 7 et 11 permettent ainsi d'adapter la longueur du bracelet au poignet de son acheteur, en fixant plus ou moins profondément les extrémités 9, 13 des brins du bracelet dans les éléments 1, 2 du fermoir. Afin que ce dernier reste au milieu de la largeur du poignet, quand la montre est elle-même sur le poignet au milieu de sa largeur, les longueurs des extrémités 9, 13 des brins du bracelet engagées dans les éléments 1, 2 seront choisies égales.The holes 7 and 11 thus make it possible to adapt the length of the bracelet to the wrist of its purchaser, by fixing the ends 9, 13 of the bracelet strands more or less deeply in the elements 1, 2 of the clasp. So that the latter remains in the middle of the width of the wrist, when the watch is itself on the wrist in the middle of its width, the lengths of the ends 9, 13 of the strands of the bracelet engaged in the elements 1, 2 will be chosen equal .

On remarquera que le mode décrit de fixation des brins du bracelet aux éléments du fermoir convient également bien à tous les genres de bracelets, en cuir, en tissu, en plastique ou métalliques. Il n'est plus nécessaire de fabriquer des éléments différents pour attacher les brins du bracelet à la montre et au fermoir.It will be noted that the described method of fixing the strands of the bracelet to the elements of the clasp is also well suited to all kinds of bracelets, leather, fabric, plastic or metal. It is no longer necessary to make different elements to attach the strands of the bracelet to the watch and the clasp.

Pour faciliter la fermeture du bracelet, la face externe des flancs de l'élément 2 présente deux portions de surface obliques 15, 16. De plus, les parties repliées 17, formant la face de l'élément 1 reposant sur le poignet, sont éliminées sur un peu plus de la moitié de la longueur de l'élément 1, à partir de son extrémité recevant l'élément 2. Dans cette même partie de l'élément 1, la face interne des flancs 12 présente aussi une portion de surface oblique 18, de même inclinaison que les portions de surface 15, 16 et qui s'étend depuis son bord inférieur jusqu'à un épaulement 19.To facilitate the closing of the bracelet, the external face of the sides of the element 2 has two oblique surface portions 15, 16. In addition, the folded parts 17, forming the face of the element 1 resting on the wrist, are eliminated. over a little more than half the length of the element 1, from its end receiving the element 2. In this same part of the element 1, the internal face of the sides 12 also has a portion of oblique surface 18, with the same inclination as the surface portions 15, 16 and which extends from its lower edge to a shoulder 19.

La fermeture du bracelet est effectuée en plaçant l'élément 2 sous l'élément 1, comme le montre la Fig. 3, puis en pressant les deux éléments du fermoir l'un contre l'autre, afin de les amener dans la position de la Fig. 4 par engagement à cran de l'élément 2 dans l'élément 1. Contrairement à l'élément 2, qui, en section, est entièrement fermé, l'élément 1 présente une fente longitudinale 20 au milieu de sa paroi reposant sur le poignet, afin de conférer à ses flancs l'élasticité nécessaire à l'engagement à cran décrit. Après cet engagement, l'élément 2 peut coulisser librement entre la paroi supérieure 3, l'épaulement 19 et la portion de surface oblique 18 de l'élément 1.The bracelet is closed by placing the element 2 under the element 1, as shown in FIG. 3, then by pressing the two elements of the clasp one against the other, in order to bring them into the position of FIG. 4 by notch engagement of element 2 in element 1. Unlike element 2, which, in section, is completely closed, element 1 has a longitudinal slot 20 in the middle of its wall resting on the wrist , in order to give its sides the elasticity necessary for the notched engagement described. After this engagement, the element 2 can slide freely between the upper wall 3, the shoulder 19 and the oblique surface portion 18 of the element 1.

L'ajustement de la longueur du bracelet aux dimensions du poignet de son porteur, par engagement des barrettes 10, 14 dans l'une des paires de trous 7, 11 des éléments 1, 2, est réalisé de façon que le bracelet plaque convenablement sur le poignet, lorsque l'élément 2 est entièrement engagé dans l'élément 1, au point que son extrémité postérieure soit à fleur de l'ouverture de l'élément 1.The adjustment of the length of the bracelet to the dimensions of the wrist of its wearer, by engagement of the bars 10, 14 in one of the pairs of holes 7, 11 of the elements 1, 2, is carried out so that the bracelet plates suitably on the wrist, when the element 2 is fully engaged in the element 1, to the point that its rear end is flush with the opening of the element 1.

Pour retenir normalement l'élément 2 dans cette position, l'élément 1 contient un organe élastique constitué par une lame de ressort 21 (Fig. 2) qui s'étend sur toute la longueur de l'élément 1. Cette lame prend place dans le canal longitudinal 4. Son extrémité 22, qui est adjacente à celle, 13, du brin du bracelet, est fixée au fond du canal 4: A son autre extrémité, faisant saillie de l'élément 1, la lame 21 présente un élément préhensible, qui est constitué par un double pliage 23 de son extrémité. Sur sa face tournée vers l'intérieur de l'élément 1, Ia lame 21 porte une rangée de dents de loup 24, de mêmes dimensions que les dents 6 de l'élément 2 et qui sont normalement en prise avec ces dernières pour verrouiller l'élément 2 dans l'élément 1.To normally retain the element 2 in this position, the element 1 contains an elastic member constituted by a spring leaf 21 (Fig. 2) which extends over the entire length of the element 1. This leaf takes place in the longitudinal channel 4. Its end 22, which is adjacent to that, 13, of the bracelet strand, is fixed to the bottom of the channel 4: At its other end, projecting from the element 1, the blade 21 has a gripping element, which is constituted by a double folding 23 of its end. On its inside-facing side of the element 1, the blade 21 carries a row of wolf teeth 24, of the same dimensions as the teeth 6 of the element 2 and which are normally engaged with the latter to lock the item 2 in item 1.

Si le volume du poignet du porteur de la montre augmente au point que le bracelet devienne gênant, celui-ci peut agrandir son bracelet à volonté, en saisissant l'extrémité 23 de la lame de ressort 21 à l'aide d'un ongle et en l'écartant de l'élément 2 du fermoir. Cet élément est alors libéré et peut être extrait de la quantité voulue de l'élément 1. Un déplacement de 0, cm de cet élément 2 est amplement suffisant pour compenser l'augmentation de volume diurne du poignet. Comme les dents 6 ne vont pas jusqu'à l'extrémité de l'élément 2, qui est adjacente à l'extrémité 9 du brin de bracelet fixé à cet élément, ces dents resteront cachées dans l'élément 1 et ne perturberont donc pas l'esthétique du fermoir après le déplacement compensatoire indiqué. Lorsque la longueur du bracelet a ainsi été adaptée aux dimensions momentanées du poignet, la lame 21 est relâchée. Ses dents 24 entrent à nouveau en prise avec la denture 6 de l'élément 2 et verrouillent par conséquent ce dernier dans sa nouvelle position. Comme les dents 6 et 24 sont relativement petites, la longueur du bracelet peut être réglée pratiquement en continu.If the volume of the wrist of the wearer of the watch increases to the point that the bracelet becomes troublesome, the latter can enlarge his bracelet at will, by grasping the end 23 of the spring leaf 21 using a fingernail and away from element 2 of the clasp. This element is then released and can be extracted from the desired quantity of element 1. A displacement of 0, cm of this element 2 is more than enough to compensate for the increase in daytime volume of the wrist. As the teeth 6 do not go to the end of the element 2, which is adjacent to the end 9 of the bracelet strand attached to this element, these teeth will remain hidden in the element 1 and will therefore not disturb the aesthetics of the clasp after the indicated compensatory movement. When the length of the bracelet has thus been adapted to the momentary dimensions of the wrist, the blade 21 is released. Its teeth 24 again engage with the teeth 6 of the element 2 and consequently lock the latter in its new position. As teeth 6 and 24 are relatively small, the length of the bracelet can be adjusted almost continuously.

Lorsque le poignet aura repris ses dimensions normales, après une période de repos, il suffira de repousser l'élément 2 dans l'élément 1, pour éviter que la montre ne tourne autour du poignet. Sous la pression exercée alors sur cet élément 2, les faces inclinées de ses dents 6 glissent sur celles des dents 24 de la lame 21, en écartant automatiquement cette dernière de l'élément 2.When the wrist has returned to its normal dimensions, after a period of rest, it will suffice to push the element 2 back into the element 1, to prevent the watch from turning around the wrist. Under the pressure then exerted on this element 2, the inclined faces of its teeth 6 slide over those of the teeth 24 of the blade 21, automatically moving the latter away from the element 2.
