Description

Domaine techniqueTechnical area

La présente invention se rapporte au domaine de l'habillage pour l'horlogerie. Elle concerne un maillon de bracelet de montre définissant un axe longitudinal selon la direction de la longueur du bracelet, et une face supérieure et une face inférieure, respectivement en référence aux côtés externe et interne dudit bracelet.The present invention relates to the field of dressing for the watch industry. It relates to a watchband link defining a longitudinal axis in the direction of the length of the bracelet, and an upper face and a lower face, respectively with reference to the outer and inner sides of said bracelet.

Etat de la techniqueState of the art

Dans le domaine des bracelets de montre, le réglage fin de la longueur du bracelet est un paramètre important qui détermine le confort d'utilisation. Pour des bracelets en cuir ou en tissu, qui peuvent être percés de trous pouvant recevoir l'ardillon d'une boucle, ou un piton d'attache d'une boucle déployante. Dans le cas des bracelets à maillons, la mise à la longueur nécessite souvent le démontage de maillons.In the field of watchbands, the fine adjustment of the length of the bracelet is an important parameter which determines the comfort of use. For leather or fabric bracelets, which can be pierced with holes that can receive the barb of a buckle, or an attachment pin of a folding clasp. In the case of bracelets with links, the setting to the length often requires the disassembly of links.

On connaît également des bracelets à maillons comportant des éléments déformables élastiquement, soit à l'intérieur des maillons, soit entre les maillons. La déformation de ces éléments élastiques permet un ajustement de la longueur du bracelet et une mise à la longueur. Toutefois, ces éléments élastiques entraînent l'exercice d'une contrainte élastique sur le poignet du porteur, qui peut ne pas être agréable. En outre, si on accroche le bracelet, sa longueur peut augmenter de manière involontaire et entraîner la perte de la montre. Un autre système de réglage est connu de CH-594 380 .Also known are bracelet links comprising elastically deformable elements, either inside the links or between the links. The deformation of these elastic elements allows an adjustment of the length of the bracelet and a setting to length. However, these elastic elements cause the exercise of elastic stress on the wrist of the wearer, which may not be pleasant. In addition, if you hang the bracelet, its length may increase unintentionally and cause the loss of the watch. Another adjustment system is known from CH-594,380 .

La présente invention a pour but de proposer un bracelet à maillons dont la longueur peut être ajustée, exempt des inconvénients ci-dessus.The present invention aims to provide a link bracelet whose length can be adjusted, free of the disadvantages above.

Divulgation de l'inventionDisclosure of the invention

De façon plus précise, l'invention concerne un maillon de bracelet de montre définissant un axe longitudinal selon la direction de la longueur du bracelet, et une face supérieure et une face inférieure, respectivement en référence aux côtés externe et interne dudit bracelet. Particulièrement à l'invention, le maillon comporte :

  • deux flancs parallèles audit axe longitudinal, chacun desdits flancs étant traversé par une ouverture oblongue orientée longitudinalement, lesdites ouvertures oblongues étant situées en regard l'une de l'autre,
  • un logement ménagé sur la face inférieure,
  • une bascule d'accrochage dotée d'un organe d'accrochage et montée pivotante dans le logement selon une direction perpendiculaire à l'axe longitudinal, entre une première position dans laquelle l'organe d'accrochage est situé en regard des ouvertures oblongues, et une deuxième position dans laquelle l'organe d'accrochage laisse libre l'espace entre les ouvertures oblongues,
  • un organe ressort pour maintenir la bascule dans sa première position, et
  • un organe de commande pour amener la bascule de sa première à sa deuxième position.
More specifically, the invention relates to a watchband link defining a longitudinal axis in the direction of the length of the bracelet, and an upper face and a lower face, respectively with reference on the outer and inner sides of said bracelet. Particularly to the invention, the link comprises:
  • two flanks parallel to said longitudinal axis, each of said flanks being traversed by an oblong opening oriented longitudinally, said oblong openings being located facing one another,
  • a housing on the underside,
  • a latching lever having a latching member and pivotally mounted in the housing in a direction perpendicular to the longitudinal axis, between a first position in which the latching member is located opposite the oblong openings, and a second position in which the fastening member leaves free space between the oblong openings,
  • a spring member for holding the rocker in its first position, and
  • a control member for bringing the latch from its first to its second position.

L'invention concerne également un bracelet comprenant une première partie munie, à l'une de ses extrémités, d'un maillon tel que défini ci-dessus, et une deuxième partie munie d'une barrette à l'une de ses extrémités. La deuxième partie est dimensionnée de manière à ce que sa barrette traverse les ouvertures oblongues du maillon. La barrette peut occuper une première position dans laquelle elle est située entre le crochet et une première extrémité des ouvertures oblongues, et une deuxième position dans laquelle elle est située entre le crochet et la deuxième extrémité des ouvertures oblongues.The invention also relates to a bracelet comprising a first portion provided at one of its ends with a link as defined above, and a second portion provided with a bar at one of its ends. The second part is dimensioned so that its bar passes through the oblong openings of the link. The bar may occupy a first position in which it is located between the hook and a first end of the oblong openings, and a second position in which it is located between the hook and the second end of the oblong openings.

Mode(s) de réalisation de l'inventionMode (s) of realization of the invention

Les figures 1 et 2 montrent un maillon 10 de bracelet de montre selon l'invention. Selon l'exemple proposé, il est de forme générale parallélépipédique, mais d'autres formes sont envisageables. On définit son axe longitudinal A-A selon la direction de la longueur du bracelet (fig. 3 et 4). On définit également une face supérieure 12 et une face inférieure 14, la face supérieure 12 étant celle qui est destinée à être visible lorsque le bracelet comportant ce maillon est porté, la face inférieure 14 étant celle qui est destinée à être au contact du bras du porteur.The Figures 1 and 2 show a watchband link 10 according to the invention. According to the proposed example, it is of parallelepipedal general shape, but other forms are conceivable. We define its longitudinal axis AA in the direction of the length of the bracelet ( Fig. 3 and 4 ). An upper face 12 and a lower face 14 are also defined, the upper face 12 being that which is intended to be visible when the bracelet comprising this link is worn, the lower face 14 being that which is intended to be in contact with the arm of the carrier.

Le maillon définit deux flancs 16 parallèles audit axe longitudinal. Chacun de ces flancs est traversé par une ouverture oblongue 18 orientée sensiblement selon l'axe longitudinal A-A. Ces ouvertures oblongues 18 sont situées en regard l'une de l'autre de manière à permettre, comme on le verra par la suite, la translation d'une barrette ou d'une goupille traversant ces ouvertures, d'une extrémité à l'autre de l'ouverture.The link defines two flanks 16 parallel to said longitudinal axis. Each of these flanks is traversed by an oblong opening 18 oriented substantially along the longitudinal axis A-A. These oblong openings 18 are located facing one another so as to allow, as will be seen later, the translation of a bar or a pin passing through these openings, from one end to the other. other of the opening.

La face inférieure 14 du maillon reçoit un logement 20 dimensionné de manière à recevoir une bascule d'accrochage 22. Cette dernière comporte, à l'une de ses extrémités, un crochet 24 servant d'organe d'accrochage. La bascule 22 est montée pivotante dans le logement selon une direction perpendiculaire à l'axe longitudinal, c'est-à-dire parallèlement aux barrettes reliant les maillons les uns aux autres. La bascule 22 est susceptible d'être déplacée entre une première position dans laquelle le crochet est situé en regard des ouvertures oblongues, et une deuxième position dans laquelle le crochet laisse libre l'espace entre les ouvertures oblongues. On remarquera également que les ouvertures oblongues 18 débouchent dans le logement 20.The lower face 14 of the link receives a housing 20 sized to receive a latching lever 22. The latter comprises, at one of its ends, a hook 24 serving as hooking member. The latch 22 is pivotally mounted in the housing in a direction perpendicular to the longitudinal axis, that is to say parallel to the bars connecting the links to each other. The rocker 22 can be moved between a first position in which the hook is located opposite the oblong openings, and a second position in which the hook leaves free space between the oblong openings. It will also be noted that the oblong openings 18 open into the housing 20.

Le maillon 10 comporte encore un organe ressort 26 monté dans le fond du logement 20 et agencé de manière à exercer sur la bascule 22 une force tendant à la maintenir dans sa première position. En l'espèce, on peut prévoir deux ressorts agissant symétriquement sur deux coins de la bascule, pour la maintenir droite par rapport à son axe de pivotement. On peut prévoir davantage de ressort dès lors que la force qu'ils exercent est répartie sur la bascule.The link 10 further comprises a spring member 26 mounted in the bottom of the housing 20 and arranged to exert on the rocker 22 a force tending to maintain it in its first position. In this case, one can provide two springs acting symmetrically on two corners of the rocker, to keep it straight relative to its pivot axis. More spring can be provided when the force they exert is distributed on the rocker.

La bascule 22 est amenée à sa deuxième position, en contraignant l'organe ressort, par une action sur l'extrémité de la bascule 22 opposée à l'organe d'accrochage en référence à son axe de pivotement. L'homme du métier pourrait éventuellement prévoir un organe de commande de type poussoir, pour agir sur la bascule 22. On peut aussi prévoir sur la zone d'actionnement de la bascule, une structure en relief améliorant l'ergonomie et permettant de visualiser le maillon 10 lorsqu'il est parmi les autres maillons d'un bracelet.The latch 22 is brought to its second position, by constraining the spring member, by an action on the end of the rocker 22 opposite to the latching member with reference to its pivot axis. The person skilled in the art could possibly provide a push-type control member to act on the rocker 22. It is also possible to provide on the actuating zone of the rocker, a relief structure improving the ergonomics and making it possible to visualize the link 10 when it is among the other links of a bracelet.

Le logement 20 est avantageusement dimensionné de manière à ce que la bascule 22 y soit entièrement logée lorsqu'elle est dans sa première position, ce qui permet au dispositif de s'intégrer parfaitement dans un bracelet, sans gêner le porteur. En outre, la bascule 22 est agencée de manière à ce que l'extrémité de la bascule 22 comportant le crochet 24 dépasse à l'extérieur du logement 20 lorsque la bascule 22 est dans sa deuxième position. On notera qu'un agencement différent du crochet de verrouillage 24 serait possible, avec une autre cinématique, mais la solution décrite est la plus adaptée en termes d'ergonomie et d'encombrement du système.The housing 20 is advantageously dimensioned so that the rocker 22 is fully housed when it is in its first position, which allows the device to integrate perfectly in a bracelet without disturbing the wearer. In addition, the rocker 22 is arranged so that the end of the rocker 22 having the hook 24 protrudes outside the housing 20 when the rocker 22 is in its second position. Note that a different arrangement of the locking hook 24 would be possible with another kinematic, but the solution described is the most suitable in terms of ergonomics and congestion system.

Plus particulièrement, ce maillon 10 est destiné à constituer le dernier maillon d'une première partie d'un bracelet. Ce dernier comporte également une deuxième partie munie d'une goupille 28 avec tenons à l'une de ses extrémités. On peut remarquer sur les dessins que les ouvertures oblongues sont destinées à recevoir cette goupille 28. Les maillons formant l'extrémité de la deuxième partie ne sont pas représentés mais sont agencés de manière à permettre le positionnement du maillon 10 et la mise en place de la goupille 28 dans les ouvertures oblongues 18, grâce aux tenons de la goupille.More particularly, this link 10 is intended to be the last link of a first part of a bracelet. The latter also comprises a second portion provided with a pin 28 with tenons at one of its ends. It may be noted in the drawings that the oblong openings are intended to receive this pin 28. The links forming the end of the second part are not shown but are arranged to allow the positioning of the link 10 and the establishment of the pin 28 in the oblong openings 18, thanks to the pins of the pin.

La goupille 28, les ouvertures oblongues 18 et le crochet 24 sont dimensionnés de manière à ce que, lorsque la bascule 22 est dans sa première position, la goupille 28 puisse occuper :

  • une première position dans laquelle elle est située entre le crochet 24 et une première extrémité des ouvertures oblongues 18, et
  • une deuxième position dans laquelle elle est située entre le crochet 24 et la deuxième extrémité des ouvertures oblongues 18.
The pin 28, the oblong openings 18 and the hook 24 are dimensioned so that, when the rocker 22 is in its first position, the pin 28 can occupy:
  • a first position in which it is located between the hook 24 and a first end of the oblong openings 18, and
  • a second position in which it is located between the hook 24 and the second end of the oblong openings 18.

Ainsi, le crochet 24 est sensiblement positionné de manière à séparer l'espace défini entre les ouvertures oblongues 18, en deux parties sensiblement égales, selon une direction perpendiculaire à l'axe longitudinal, soit une première partie du côté de la première extrémité des ouvertures oblongues 18 et une deuxième partie du côté de la deuxième extrémité des ouvertures oblongues 18.Thus, the hook 24 is substantially positioned so as to separate the space defined between the oblong openings 18, in two substantially equal parts, in a direction perpendicular to the longitudinal axis, a first portion of the side of the first end of the openings. oblong 18 and a second portion on the side of the second end of the oblong openings 18.

Le crochet 24 est dimensionné de manière à ce que la goupille 28 soit positionnée sans jeu dans ses première et deuxième positions. Ainsi, la base du crochet 24 forme, avec la paroi des ouvertures oblongues 18, un réceptacle dont la forme est sensiblement adaptée à celle de la goupille 28.The hook 24 is dimensioned so that the pin 28 is positioned without play in its first and second positions. Thus, the base of the hook 24 forms, with the wall of the oblong openings 18, a receptacle whose shape is substantially adapted to that of the pin 28.

Le crochet 24 et la goupille 28 peuvent en outre être agencés pour former un engagement à cran du crochet 24 dans la goupille 28 lorsque la bascule 22 est dans sa première position. Dans ce but, la goupille 28 comporte une creusure, non visible au dessin, dans laquelle peut prendre place le crochet 24. La goupille 28 étant libre en rotation, une pression sur la bascule 22 peut simplement dégager le cran, mais un dégagement involontaire est quasi impossible. Cette disposition permet également de maintenir une orientation contrôlée de tous les maillons les uns par rapport aux autres.The hook 24 and the pin 28 may further be arranged to form a hook engagement of the hook 24 in the pin 28 when the latch 22 is in its first position. For this purpose, the pin 28 comprises a recess, not visible in the drawing, in which can take place the hook 24. The pin 28 being free in rotation, a pressure on the rocker 22 can simply clear the notch, but an involuntary release is almost impossible. This arrangement also makes it possible to maintain a controlled orientation of all the links with respect to each other.

Dans une variante illustrée sur la figure 5, l'engagement à cran se fait par coopération entre le crochet 24 et une creusure 30 correspondante, ménagée dans le fond du logement 20, en regard du crochet 22. Le crochet s'engage à cran dans la creusure 30 lorsque la bascule 22 est dans sa première position. Le verrouillage obtenu est ainsi plus rigide que dans le mode de réalisation ci-dessus et indépendant de l'orientation relative des maillons et de la goupille 28. En outre, le verrouillage a lieu dès que la bascule est dans sa première position, indépendamment de la longueur que présente le bracelet.In an illustrated variant on the figure 5 , the notched engagement is done by cooperation between the hook 24 and a corresponding recess 30, formed in the bottom of the housing 20, facing the hook 22. The hook engages notch in the recess 30 when the latch 22 is in his first position. The locking obtained is thus more rigid than in the embodiment above and independent of the relative orientation of the Links and pin 28. In addition, locking occurs as soon as the rocker is in its first position, regardless of the length of the bracelet.

Ainsi, un bracelet comportant un maillon selon l'invention peut présenter une première longueur, dite courte, lorsque la goupille 28 est dans sa première position, visible sur la figure 1. L'organe ressort 26 et l'engagement à cran du crochet 24 garantissent le maintien de cette position en toute sécurité. Une pression sur la bascule d'accrochage 22 amène cette dernière dans sa deuxième position, en dégageant le cran par rotation de la goupille 28. Tout en maintenant la bascule 22 dans cette deuxième position, on tire sur les première et deuxième parties du bracelet pour les éloigner l'une de l'autre, ce qui amène la goupille 28 dans sa deuxième position, visible sur la figure 2. Le bracelet présente alors une deuxième longueur, dite longue. On peut alors relâcher la pression sur la bascule 22, ce qui la ramène dans sa première position et permet de garantir le maintien de cette position. Naturellement, la réduction de la longueur peut tout à fait se faire dans le sens inverse.Thus, a bracelet comprising a link according to the invention may have a first length, called short, when the pin 28 is in its first position, visible on the figure 1 . The spring member 26 and the notch engagement of the hook 24 ensure the maintenance of this position safely. Pressing on the latching lever 22 brings the latch into its second position, disengaging the notch by rotation of the pin 28. While maintaining the lever 22 in this second position, the first and second parts of the wrist strap are pulled. away from each other, which brings the pin 28 in its second position, visible on the figure 2 . The bracelet then has a second length, called long. It is then possible to release the pressure on the rocker 22, which brings it back to its first position and makes it possible to guarantee the maintenance of this position. Naturally, the reduction of the length can quite be done in the opposite direction.

Ainsi est proposé un maillon et un bracelet à maillons muni d'un tel maillon, capable d'occuper au moins deux longueurs différentes et déterminées. Selon les dimensions des maillons, l'homme du métier pourrait prévoir plusieurs crochets sur la bascule offrant ainsi davantage de positions de réglage. Le système de réglage est ainsi totalement invisible lorsque le bracelet est porté. Le bracelet est même identique à un bracelet de l'état de la technique lorsqu'il est dans sa position courte. Le bracelet muni d'un tel maillon ne compresse pas élastiquement le bras du porteur et offre une excellente fiabilité dans le maintien des positions qui ne peuvent varier accidentellement, comme avec un bracelet élastique. En outre, le maillon selon l'invention peut être inséré dans des bracelets à maillons existant, leur offrant ainsi un réglage fin de la longueur.Thus is proposed a link and a link bracelet provided with such a link, capable of occupying at least two different and determined lengths. Depending on the size of the links, the skilled person could provide several hooks on the scale thus providing more adjustment positions. The adjustment system is completely invisible when the bracelet is worn. The bracelet is identical to a bracelet of the state of the art when it is in its short position. The bracelet provided with such a link does not elastically compress the wearer's arm and offers excellent reliability in maintaining positions that can not vary accidentally, as with an elastic strap. In addition, the link according to the invention can be inserted into existing link bracelets, thus providing a fine adjustment of the length.
