Description

La présente invention se rapporte à un fermoir de bracelet. Elle concerne plus particulièrement un fermoir du type comprenant un premier élément et un deuxième élément destinés à être respectivement reliés à un premier et à un second brin d'un bracelet et un troisième élément qui relie mécaniquement de manière articulée les premier et deuxième éléments, ce fermoir comportant des moyens pour régler la longueur du bracelet de manière à l'ajuster au bras d'un porteur et qui comprennent une goupille engagée dans au moins un trou parmi une pluralité de trous transversaux, pratiqués dans le premier élément.The present invention relates to a clasp of bracelet. It relates more particularly to a clasp of the type comprising a first element and a second element intended to be respectively connected to a first and a second strand of a bracelet and a third element which mechanically connects the first and second elements, this clasp comprising means to adjust the length of the bracelet so as to adjust it on the arm of a wearer and which include a pin engaged in at least one hole among a plurality of holes transverse, practiced in the first element.

Un fermoir de ce type est décrit et représenté dans le document DGM 9 401 541. Il comporte également trois éléments. Le premier élément est relié à l'un des brins d'un bracelet. Le deuxième élément est relié mécaniquement de manière articulée au second brin du bracelet et le troisième élément relie les premier et deuxième éléments de manière articulée pour permettre l'ouverture et la fermeture du fermoir.A clasp of this type is described and represented in the document DGM 9 401 541. It also includes three elements. The first element is connected to one of the strands a bracelet. The second element is mechanically connected hinged to the second strand of the bracelet and the third element connects the first and second elements articulated to allow opening and clasp closure.

Le premier élément se présente sous la forme d'une coiffe avec une face supérieure qui couvre les autres éléments du fermoir et deux flans s'étendant longitudinalement sur les côtés du fermoir et percés d'une pluralité de trous transversaux. Cette coiffe est probablement réalisée par l'emboutissage d'une tôle d'acier inoxydable. Le trou extrême permet l'assemblage de la coiffe avec le premier brin du bracelet. Les autres trous transversaux sont destinés à recevoir une autre goupille également engagée dans un trou transversal que comporte le troisième élément, le choix du trou définissant la longueur du bracelet.The first element is in the form of a cap with an upper side which covers the others clasp elements and two extending blanks longitudinally on the sides of the clasp and pierced with a plurality of transverse holes. This headdress is probably achieved by stamping a sheet stainless steel. The extreme hole allows the assembly of the headdress with the first strand of the bracelet. Others transverse holes are intended to receive another pin also engaged in a transverse hole that has the third element, the choice of hole defining the length of the bracelet.

Cette solution permet l'assemblage de deux brins de bracelets et l'ajustement de la longueur de ce bracelet aux dimensions du bras d'un porteur. On constate toutefois que dans une telle configuration, les goupilles engagées dans les trous transversaux du premier élément exercent sur leurs parois une traction provoquant une usure et pouvant conduire à une ovalisation de ces trous, voire au désengagement de la goupille. Ce défaut réduit considérablement la durée de vie des fermoirs de ce type. Cela est dû en particulier au fait que premièrement les flans du premier élément sont peu épais afin de pouvoir être embouti et deuxièmement les efforts qu'un bracelet et en particulier son fermoir doit subir sont importants.This solution allows the assembly of two strands of bracelets and adjusting the length of this bracelet the dimensions of a wearer's arm. However, we note that in such a configuration, the pins engaged in the transverse holes of the first element exert on their walls a traction causing wear and can lead to ovalization of these holes, or even disengagement of the pin. This defect reduces considerably the lifespan of clasps of this type. This is due in particular to the fact that first blanks of the first element are not very thick in order to be able be stamped and secondly the efforts that a bracelet and in particular its clasp must undergo are important.

Pour améliorer le fermoir susmentionné, il faudrait que les parois des flans du premier élément soient plus épaisses. Il en résulterait soit que le dernier maillon ait une structure très différente des autres, ce qui augmenterait sensiblement son coût, soit que les parois des flans de la coiffe s'étendent fortement au-delà de la largeur des maillons. Dans ce dernier cas, le fermoir est élargi, ce qui est inesthétique et augmente le risque d'accrochage. En outre, la coiffe ne peut plus être fabriquée par emboutissage.To improve the above clasp, the walls of the blanks of the first element are more thick. The result would either be that the last link has a structure very different from the others, which significantly increase its cost, that the walls blanks of the cap extend strongly beyond the width of the links. In the latter case, the clasp is enlarged, which is unsightly and increases the risk hanging. In addition, the cap can no longer be made by stamping.

Un but de la présente invention est de pallier les inconvénients de l'art antérieur mentionné ci-dessus.An object of the present invention is to overcome the disadvantages of the prior art mentioned above.

Dans la solution décrite précédemment, les flans de la coiffe sont percés chacun d'une rangée de trous. L'aspect esthétique du fermoir en est affecté.In the solution described above, the blanks of the cap are drilled each with a row of holes. The aesthetic aspect of the clasp is affected.

Un autre but de la présente invention est d'améliorer l'esthétique du fermoir.Another object of the present invention is to improve the aesthetics of the clasp.

Ces buts sont atteints grâce aux caractéristiques de la revendication 1.These goals are achieved thanks to the characteristics of claim 1.

Dans cette configuration, la coiffe n'est plus soumise aux contraintes que subit le bracelet. C'est au contraire le premier élément qui est soumis à ces contraintes. En outre, le premier élément peut être réalisé dans une structure massive avec des trous garantissant un engagement optimal de la goupille, la longueur de ces trous étant au moins égale à leur diamètre. In this configuration, the cap is no longer subject to the constraints on the bracelet. Is the otherwise the first item that is subject to these constraints. In addition, the first element can be made in a massive structure with holes guaranteeing optimal engagement of the pin, the length of these holes being at least equal to their diameter.

Le premier élément 1 comprend un corps 7 et trois doigts longitudinaux 8, 9 et 10, définissant entre eux des encoches 11 et 12 (fig. 4). Les doigts 8 et 10 présentent un décrochement sur leurs côtés extérieurs, définissant des encoches 13 et 14. Les doigts 8, 9 et 10 sont percés de deux trous transversaux 15 et 16, parallèles entre eux. Du côté opposé aux doigts, le corps 7 comporte un épaulement 7'.The first element 1 comprises a body 7 and three longitudinal fingers 8, 9 and 10, defining between them notches 11 and 12 (fig. 4). Fingers 8 and 10 have a recess on their outer sides, defining notches 13 and 14. The fingers 8, 9 and 10 are pierced two transverse holes 15 and 16, mutually parallel. On the side opposite the fingers, the body 7 has a 7 'shoulder.

Le deuxième élément 2 est formé d'un bras 17 comportant deux têtes 18 et 19 occupant les deux extrémités de ce bras 17. La tête 18 présente un renflement percé d'un trou transversal, alors que la tête 19 porte un tube soudé 21 percé d'un trou 22 et s'étendant transversalement.The second element 2 is formed by an arm 17 comprising two heads 18 and 19 occupying both ends of this arm 17. The head 18 has a bulge with a transverse hole, while the head 19 carries a welded tube 21 pierced with a hole 22 and extending transversely.

Le troisième élément est formé d'un bras 23 comportant deux têtes 24 et 25 occupant les deux extrémités du bras 23. La tête 24 présente un renflement percé d'un trou 26. Elle comporte de manière connue deux parties transversales placées de part et d'autre de la tête 18. La tête 25 est configurée pour être insérée dans les encoches 11 et 12. Elle présente un renflement percé d'un trou transversal 28 et comporte une fente longitudinale et médiane 27.The third element is formed by an arm 23 comprising two heads 24 and 25 occupying both ends of the arm 23. The head 24 has a bulge drilled with a hole 26. It comprises in known manner two transverse parts placed on either side of the head 18. head 25 is configured to be inserted in notches 11 and 12. It has a pierced bulge a transverse hole 28 and has a slot longitudinal and median 27.

La coiffe 4 comporte une première partie 29 avec une section transversale en forme de U dont la zone médiane recouvre le premier élément et dont les flans 29' et 29" s'étendent de part et d'autre du premier élément 1. La coiffe 4 s'étend en outre jusqu'à la tête 19 du deuxième élément 2. Elle comporte de plus une pièce rapportée 30, dont une partie 30' fait saillie longitudinalement. La partie supérieure de la pièce 30 est soudée à la face inférieure de la coiffe 4. La saillie 30' est engagée sous l'épaulement 7' du corps 7. Les flans 29' et 29" (fig. 4) comportent chacun un seul trou transversal 31. Afin d'améliorer la rigidité de l'assemblage que constituent le premier élément 1 et la coiffe 4, un film élastique peut être interposé entre l'épaulement 7' et la saillie 30' ou la face inférieure de la partie 29 de la coiffe. De plus, les surfaces de contact entre l'épaulement et la saillie peuvent avantageusement être légèrement inclinées.The cap 4 has a first part 29 with a U-shaped cross section with the middle area covers the first element and whose blanks 29 'and 29 " extend on either side of the first element 1.

In order improve the rigidity of the assembly constituted by the first element 1 and the cap 4, an elastic film can be interposed between the shoulder 7 'and the projection 30' or the underside of part 29 of the cap. Moreover, the contact surfaces between the shoulder and the projection can advantageously be slightly inclined.

Les brins 6 et 7 du bracelet sont formés de maillons 32 alignés longitudinalement et dont les extrémités sont de formes complémentaires et percées de trous transversaux 33 et 34. The strands 6 and 7 of the bracelet are formed of links 32 aligned longitudinally and whose ends are of complementary shapes and pierced with transverse holes 33 and 34.

Les différentes pièces de ce fermoir sont assemblées les unes aux autres au moyen de goupilles ou de vis. Plus précisément, le premier élément 1 est relié au troisième élément 3 au moyen d'une vis 35 engagée dans les trous 16 et 28 des premier et troisième éléments 1 et 3. Dans la configuration des figures 1, 3 et 4, le maillon extrême 32' du brin 5 est assemblé de manière articulée au premier élément 1 par une goupille 36 engagée dans les trous 15 et 33' du premier élément 1 respectivement du maillon 32'. Cette goupille 36 pénètre également dans les trous 31 de la coiffe 4. La goupille 36 peut être avantageusement filetée en son extrémité 36' (fig. 4) et vissée dans un taraudage que comporte la paroi interne du trou 33.The different parts of this clasp are assembled to each other by means of pins or screws. More specifically, the first element 1 is connected to the third element 3 by means of a screw 35 engaged in the holes 16 and 28 of the first and third elements 1 and 3. In the configuration of Figures 1, 3 and 4, the extreme link 32 'of the strand 5 is assembled in an articulated manner to the first element 1 by a pin 36 engaged in the holes 15 and 33 'of the first element 1 respectively of the link 32'. This pin 36 also enters the holes 31 of the cap 4. The pin 36 can advantageously be threaded at its end 36 '(fig. 4) and screwed into a internal thread of the internal wall of the hole 33.

On notera que les parois des trous 15 et 16 du premier élément 1, et les trous 28 et 33 du deuxième élément 2 respectivement du maillon 32 ont tous une longueur supérieure à leur diamètre. Une telle structure garantit une liaison mécanique solide et fiable au fermoir, sans solliciter les parois du trou 31 dans chacun des deux flans 29' et 29''.It will be noted that the walls of the holes 15 and 16 of the first element 1, and holes 28 and 33 of the second element 2 respectively of link 32 all have a length greater than their diameter. Such a structure guarantees a solid and reliable mechanical connection to clasp, without requesting the walls of hole 31 in each of the two blanks 29 'and 29' '.

Dans la configuration représentée à la figure 2, tant le troisième élément 3 que le maillon 32' sont reliés mécaniquement et de manière articulée au premier élément 1 par la goupille 36, engagée dans les trous 15, 28 et 33' du premier élément 1, du troisième élément 3 respectivement du maillon 32'. Dans l'une comme dans l'autre des configurations mentionnées, le troisième élément 3 est relié mécaniquement de manière articulée au deuxième élément 2 au moyen d'une goupille 37 engagée à demeure dans les trous de la tête 18 de l'élément 2 respectivement de la tête 24 de l'élément 3. Le deuxième élément 2 est relié au maillon extrême 32" du brin 6 par une goupille 38 engagée dans le tube 21 de l'élément 2 et dans les trous 33" des extrémités de ce maillon 32" voisine du fermoir.In the configuration shown in Figure 2, both the third element 3 that the link 32 'are connected mechanically and articulated to the first element 1 by pin 36, engaged in holes 15, 28 and 33 ' of the first element 1, of the third element 3 respectively of the link 32 '. In one as in the other of the configurations mentioned, the third element 3 is mechanically connected in an articulated manner to the second element 2 by means of a pin 37 engaged at remains in the holes of the head 18 of the element 2 respectively of the head 24 of the element 3. The second element 2 is connected to the 32 "end link of strand 6 by a pin 38 engaged in the tube 21 of the element 2 and in the holes 33 "of the ends of this link 32" next to the clasp.

On notera enfin que le fermoir est maintenu fermé au moyen d'un engagement à cran entre les bras 17 et 23 des deuxième et troisième éléments 2 et 3, schématiquement représenté et référencé 39 sur les figures 1, 2 et 3. Sur la figure 4, on peut constater que le trou 16 est borgne dans le doigt 8. Toutefois, dans une variante, il est possible de prévoir ce trou traversant des deux côtés de l'élément 1 dans lequel une goupille est introduite libre. Pour les autres goupilles, on utilise les solutions de fixation usuelles, par chassage, vissage ou de type à ressort, bien connues de l'homme du métier.Finally, note that the clasp is kept closed at by means of a notched engagement between the arms 17 and 23 of the second and third elements 2 and 3, schematically shown and referenced 39 in Figures 1, 2 and 3. On Figure 4, we can see that the hole 16 is blind in finger 8. However, in a variant, it is possible to provide this through hole on both sides of element 1 into which a pin is inserted free. For the other pins, we use the solutions of usual fixing, by driving, screwing or type spring, well known to those skilled in the art.

Comme cela a été expliqué ci-dessus, le fermoir présente une structure qui permet de régler la longueur du bracelet, pour l'adapter aux dimensions du bras du porteur. Dans une première étape, la mise de longueur se fait de manière approximative, en enlevant ou en ajoutant un ou plusieurs maillons 32 à l'un et/ou l'autre des brins 5 ou 6. Un ajustement plus fin est réalisé en reliant le troisième élément 3 au premier élément 1 par la vis 35 ou la goupille 36. La distance entre cette goupille et la vis étant sensiblement égale à la moitié de la longueur d'un maillon, il est ainsi possible d'obtenir un ajustement deux fois plus précis que cela ne peut se faire avec les seuls maillons.As explained above, the clasp has a structure that allows you to adjust the length of the bracelet, to adapt it to the dimensions of the arm of the carrier. In a first step, the length setting is done roughly, by removing or adding one or more links 32 to one and / or the other of the strands 5 or 6. A finer adjustment is made by connecting the third element 3 to the first element 1 by the screw 35 or the pin 36. The distance between this pin and the screw being substantially equal to half the length of a link, it is thus possible to obtain an adjustment twice as precise as it can be with only links.

Il est bien entendu que dans le mode de réalisation présenté sur les figures 1 à 4, il est possible d'augmenter la longueur des doigts 8, 9 et 10, et de pratiquer plus de trous transversaux, plus ou moins rapprochés les uns des autres, de manière à affiner encore l'ajustement de la longueur du bracelet. Par ailleurs, il est évident que le nombre de ces doigts peut être réduit ou au contraire augmenté sans pour autant sortir du cadre de l'invention. De plus, diverses variantes pour l'agencement desdits doigts de l'élément 1 et des parties correspondantes de l'élément 3 et du maillon 32' sont envisageables, notamment la suppression du doigt 9 et la tête 25 en une seule partie.It is understood that in the embodiment shown in Figures 1 to 4, it is possible increase the length of fingers 8, 9 and 10, and make more cross holes, more or less closer together, so as to further refine adjusting the length of the bracelet. Besides, it obviously the number of these fingers can be reduced or on the contrary increased without departing from the framework of the invention. In addition, various variants for the arrangement of said fingers of element 1 and of the parts of element 3 and link 32 'are possible, in particular the removal of finger 9 and the 25 head in one part.

Le mode de réalisation illustré aux figures 5 à 8 comporte comme celui décrit en référence aux figures 1 à 4 trois éléments référencés de 1 à 3. Le premier élément 1 est relié à l'un des brins 5 d'un bracelet, alors que le deuxième élément 2 est relié à l'autre brin 6. Le troisième élément 3 relie les premier et deuxième éléments de manière articulée. Ce mode de réalisation diffère de celui précédemment décrit par le fait que le fermoir présente une symétrie.The embodiment illustrated in Figures 5 to 8 behaves like that described with reference to Figures 1 to 4 three elements referenced from 1 to 3. The first element 1 is connected to one of the strands 5 of a bracelet, while the second element 2 is connected to the other strand 6. The third element 3 connects the first and second elements articulated. This embodiment differs from the one previously described by the fact that the clasp has symmetry.

Comme la structure du deuxième élément 2 est la même que celle du premier élément 1, les mêmes pièces portent la même référence, complétée par la lettre "a" pour les pièces associées au deuxième élément 2. Les éléments similaires au premier mode de réalisation ne seront pas tous à nouveau décrit ici.As the structure of the second element 2 is the same as that of the first element 1, the same parts bear the same reference, supplemented by the letter "a" for parts associated with the second element 2. The elements similar to the first embodiment will not all described again here.

Les coiffes 4 et 4a comportent chacune une première partie 29 et 29a avec une section transversale en forme de U dont la zone médiane recouvre respectivement le premier et le deuxième élément 1 et 2 et dont les flans 29', 29", 29'a et 29a" s'étendent respectivement de part et d'autre du premier et du deuxième élément 1 et 2 (figure 8). Les coiffes 4 et 4a comportent en outre chacune une pièce 30, 30a, munie d'une partie 30', 30a' faisant saillie longitudinalement. Les pièces 30 et 30a sont soudées respectivement à la face inférieure des coiffes 4 et 4a et forment respectivement une paroi latérale transversale de ces deux coiffes. Les saillies 30' et 30a' sont respectivement engagées sous les épaulements 7' et 7a' des corps 7 et 7a. Les flans 29', 29" d'une part, 29a' et 29a" d'autre part, comportent respectivement des trous transversaux 31 et 31a (figure 8).Caps 4 and 4a each have a first part 29 and 29a with a cross section in the form of U whose median zone respectively covers the first and the second element 1 and 2 and whose blanks 29 ′, 29 ", 29'a and 29a "extend respectively on both sides of the first and second element 1 and 2 (figure 8). The caps 4 and 4a each further comprise a part 30, 30a, provided with a part 30 ', 30a' projecting longitudinally. Parts 30 and 30a are welded respectively on the underside of caps 4 and 4a and respectively form a transverse side wall of these two headdresses. The projections 30 'and 30a' are respectively engaged under the shoulders 7 'and 7a' of bodies 7 and 7a. The blanks 29 ', 29 "on the one hand, 29a' and 29a" on the other hand, respectively have holes transverse 31 and 31a (Figure 8).

La structure du bracelet est identique à celle présentée aux figures 1 à 4. Ce dernier est également formé de maillons 32 alignés longitudinalement et dont les extrémités sont de formes complémentaires et percées de trous transversaux 33 et 34.The structure of the bracelet is identical to that shown in Figures 1 to 4. The latter is also formed of links 32 aligned longitudinally and whose ends are of complementary shapes and pierced with transverse holes 33 and 34.

Le troisième élément 3, qui relie les premier et deuxième éléments 1 et 2, comprend trois pièces articulées portant les références 40, 40a et 41. Les pièces 40 et 40a sont identiques. Elles comprennent dans leur partie centrale un bras portant la référence 42 et 42a ainsi qu'à chaque extrémité du bras, une tête 43 et 44, respectivement 43a et 44a. Les têtes 43 et 44, 43a et 44a sont chacune percées d'un trou respectivement référencé 45, 46, 45a et 46a. La pièce 41 présente une même structure, avec un bras 47 et deux têtes 48 et 49 également percées de trous.The third element 3, which connects the first and second elements 1 and 2, includes three articulated parts bearing the references 40, 40a and 41. Exhibits 40 and 40a are the same. They understand in their part central one arm bearing the reference 42 and 42a as well as each end of the arm, a head 43 and 44, 43a and 44a respectively. Heads 43 and 44, 43a and 44a are each drilled with a hole respectively referenced 45, 46, 45a and 46a. Exhibit 41 has the same structure, with one arm 47 and two heads 48 and 49 also with holes.

De manière comparable au fermoir selon le premier mode de réalisation, les pièces sont assemblées les unes aux autres deux à deux et de manière articulée, au moyen des goupilles ou de vis. Ainsi les pièces 40 et 40a sont respectivement reliées aux éléments 1 et 2 au moyen de vis 52 et 52a ou des goupilles 36 et 36a engagées dans les trous 45 et 45a des pièces 40 et 40a et dans l'un ou l'autre des trous 15 et 16, respectivement 15a et 16a des éléments 1 et 2. Les pièces 40 et 40a sont respectivement reliées à la pièce 41 au moyen de goupilles 53 et 53a engagées dans les trous 46 et 46a des pièces 40 et 40a et dans les trous percés dans les têtes 48 et 49 de la pièce 41.Comparable to the clasp according to the first embodiment, the parts are assembled together to the others two by two and in an articulated way, by means pins or screws. Thus parts 40 and 40a are respectively connected to elements 1 and 2 by means of screws 52 and 52a or pins 36 and 36a engaged in the holes 45 and 45a of parts 40 and 40a and in one or the other of holes 15 and 16, respectively 15a and 16a of elements 1 and 2. Parts 40 and 40a are respectively connected to the part 41 by means of pins 53 and 53a engaged in the holes 46 and 46a of the parts 40 and 40a and in the holes drilled in the heads 48 and 49 of the part 41.

Le fermoir comporte également des moyens de verrouillage à cran réalisés par l'engagement réciproque d'une partie des bras 42 et 42a avec une partie du bras 47, schématiquement représentés et référencés en 39 et 39a.The clasp also includes means for notch locking achieved by mutual engagement of a part of the arms 42 and 42a with a part of the arm 47, schematically represented and referenced in 39 and 39a.

Ainsi qu'on peut le constater en comparant les configurations des figures 5 et 6, les faces latérales transversales des coiffes 4 et 4a définissent ou non un espace entre elles, selon que le troisième élément est engagé dans les goupilles 36, 36a ou les vis 52, 52a. Il est possible de combler cet espace par l'adjonction d'une pièce rapportée 54, fixée de manière amovible au moyen notamment d'une vis 55 sur la pièce 41 du troisième élément 3.As can be seen by comparing the configurations of Figures 5 and 6, the side faces transverse caps 4 and 4a or not define a space between them, depending on whether the third element is engaged in pins 36, 36a or screws 52, 52a. he is possible to fill this space by adding a insert 54, removably attached by means including a screw 55 on part 41 of the third item 3.

On remarquera que comme les deux éléments 1 et 2 permettent ici un réglage de la longueur du bracelet fermé, on peut ajuster avec une précision 1/3 et 2/3 de la longueur d'un maillon. A la figure 5, la longueur est augmentée d'un tiers de maillon relativement à la configuration de la figure 6, alors que cette augmentation est de deux tiers de maillon à la figure 9.Note that like the two elements 1 and 2 here allow adjustment of the length of the bracelet closed, you can adjust with precision 1/3 and 2/3 of the length of a link. In Figure 5, the length is increased by a third of the link relative to the configuration of Figure 6, while this increase is two-thirds of the link in Figure 9.

La figure 9 est une variante de réalisation où la coiffe 4a comporte une visière 56 recouvrant au moins partiellement la coiffe 4 aussi bien dans l'une que dans l'autre des positions de réglage. Cette solution permet d'éviter l'usage d'une pièce rapportée, tout en conservant l'avantage d'un ajustement fin de la longueur du bracelet. Dans une autre variante, non représentée, on pourrait utiliser des coiffes différentes selon la position de réglage de la longueur du bracelet.Figure 9 is an alternative embodiment where the cap 4a has a visor 56 covering at least partially the cap 4 both in one and in the other of the adjustment positions. This solution allows to avoid the use of an added piece, while keeping the advantage of fine adjustment of the length of the bracelet. In another variant, not shown, one could use different caps depending on the position of bracelet length adjustment.

Les fermoirs tels que décrits ci-dessus permettent de considérablement réduire les défauts que présentent les fermoirs selon l'état de la technique. Plus précisément, le trou pratiqué dans les flans de la coiffe ne participe plus à la chaíne que constituent le fermoir, les brins du bracelet et la montre. De la sorte, lorsque la montre est accrochée, l'effort s'applique uniquement sur des parois de trous réalisées dans des pièces massives. L'usure en est ainsi considérablement réduite.The clasps as described above allow significantly reduce the defects that clasps according to the state of the art. More precisely, the hole made in the blanks of the cap does not participate more to the chain that constitute the clasp, the strands of bracelet and watch. So when the watch is hooked, the force applies only on walls holes made in solid parts. Wear in is thus considerably reduced.

En outre, la coiffe est fixée rigidement à l'élément de réglage, longitudinalement d'un côté par l'engagement d'une saillie sous un épaulement, de l'autre par une goupille et transversalement par les flans de la coiffe. De la sorte, l'ouverture et la fermeture du fermoir peut être effectuée en toute sécurité. On notera que durant cette opération, la goupille qui solidarise le premier élément à la coiffe n'est que peu sollicitée.In addition, the cap is rigidly attached to the element. adjustment, longitudinally on one side by engagement one projection under one shoulder, the other by a pin and transversely by the blanks of the cap. In this way, the opening and closing of the clasp can be carried out safely. Note that during this operation, the pin that secures the first element to the cap is only little requested.

Les flans de la coiffe améliorent l'esthétique du bracelet en cachant les trous supplémentaires destinés à assurer la mise de longueur du bracelet.The blanks of the cap improve the aesthetics of the bracelet hiding the additional holes intended for ensure the length of the bracelet.

Finalement, il est clair que l'invention ne se limite pas à des bracelets à maillons, mais peut également s'appliquer à d'autres types de bracelet et notamment à des bracelets ayant des brins au moins partiellement en cuir ou en matériaux souples.Finally, it is clear that the invention is not limited not to link bracelets, but can also apply to other types of bracelet and in particular to bracelets having strands at least partially in leather or flexible materials.
