Description

ELEMENT DE LIAISON D’UNE EXTREMITE D’UN BRIN DE BRACELET A UN  CONNECTING ELEMENT OF AN END OF A BRACELET STRAND TO A
OBJET MUNI D’UNE BARRETTE  OBJECT PROVIDED WITH A BAR
Domaine technique Technical area
La présente invention se rapporte au domaine des accessoires, notamment pour l’horlogerie ou la joaillerie. Elle concerne, plus particulièrement, un élément de liaison adapté pour réaliser un fermoir de bracelet ou encore un organe de fixation réversible sans outil d’un brin de bracelet à une barrette de fixation entre les cornes d’une boite de montre bracelet.  The present invention relates to the field of accessories, in particular for watchmaking or jewelry. It relates, more particularly, to a connecting element suitable for producing a bracelet clasp or even a tool-less reversible fixing member from a bracelet strand to a fixing bar between the horns of a bracelet watch case.
Etat de la technique State of the art
Dans le domaine de la joaillerie et l’horlogerie, on connaît un très grande nombre de dispositifs de fixation de brins de bracelets, que ce soit de type fermoir pour joindre deux brins de bracelet entre eux afin de permettre la tenue d’un objet (bijou, montre) au poignet d’un utilisateur ou encore de type connecteur afin de joindre une extrémité libre d’un dit brin à l’objet lui-même. In the field of jewelry and watchmaking, a very large number of devices for attaching bracelet strands are known, whether of the clasp type for joining two strands of bracelet together so as to allow an object to be held ( jewel, watch) on the wrist of a user or of the connector type in order to join a free end of a said strand to the object itself.
Dans le domaine de l’horlogerie, on connaît de très nombreux dispositifs de fixation de brins de bracelets à une boîte de montre, plus ou moins complexes et rapides à mettre en œuvre pour assurer l'assemblage d'un bracelet aux cornes de la boîte de montre. Le système de fixation le plus commun reste l’utilisation d’une barrette insérée dans une extrémité de chaque brin de bracelet à fixer à la boite de montre suivant une direction perpendiculaire à la direction longitudinale d’extension du brin et dont les extrémités font saillie hors du passant pour permettre leur insertion dans un orifice généralement cylindrique de diamètre correspondant ménagé dans les cornes de la boîte. La longueur totale de la barrette est bien entendue choisie supérieure à la distance séparant les cornes de la boîte dans laquelle ses extrémités sont insérées. In the field of watchmaking, numerous devices are known for attaching strands of bracelets to a watch case, more or less complex and quick to implement in order to assemble a bracelet to the horns of the case. of watch. The most common fastening system remains the use of a bar inserted in one end of each strand of bracelet to be fixed to the watch case in a direction perpendicular to the longitudinal direction of extension of the strand and the ends of which protrude. out of the way to allow their insertion into a generally cylindrical orifice of corresponding diameter formed in the horns of the box. The total length of the bar is of course chosen to be greater than the distance separating the horns from the box in which its ends are inserted.
Afin de conférer un caractère amovible à la fixation, les extrémités des barrettes sont usuellement montées mobiles élastiquement suivant l’axe longitudinal de la barrette de manière à permettre leur insertion et leur retrait des orifices formés dans les cornes à l’aide de pinces ou poinçon idoines. In order to impart a removable character to the fastening, the ends of the bars are usually mounted resiliently movable along the longitudinal axis of the bar so as to allow their insertion and removal from the orifices formed in the horns using suitable pliers or punch.
Ce système de fixation est irréprochable sur sa fonction première de liaison des brins de bracelets à la boîte de montre. Toutefois, il s’avère mal pratique à l’usage. En effet, les extrémités des barrettes présentent en moyenne des diamètres de quelques dixièmes de millimètres et leur accès et manipulation sont très délicats pour les utilisateurs. Aussi, les utilisateurs qui veulent changer leurs bracelets eux même souvent altèrent de manière irréversible, par manque de maîtrise et/ou d’outils adéquats, soit les brins de bracelets, soit les barrettes, soit la boîte de la montre ou encore tous à la fois. De telles altérations sont au mieux inesthétiques (rayures, déformations) au pire invalidantes de la bonne fonctionnalité du bracelet. Aussi sur des produits de bonne facture constitués de matières nobles tels que cuirs, or ou titane les utilisateurs préfèrent souvent ne pas effectuer le changement de bracelet eux-mêmes et renvoient leur montre en boutique ou en manufacture afin d’y faire changer le bracelet, avec le coût et désagrément associé. This fixing system is flawless on its primary function of connecting the strands of bracelets to the watch case. However, it turns out to be impractical to use. Indeed, the ends of the bars have on average diameters of a few tenths of a millimeter and their access and handling are very delicate for users. Also, users who want to change their straps themselves often alter irreversibly, for lack of control and / or adequate tools, either the bracelet strands, the barrettes, the watch case or all at the same time. time. Such alterations are at best unsightly (scratches, deformations) at worst disabling the good functionality of the bracelet. Also on products of good quality made of noble materials such as leathers, gold or titanium, users often prefer not to make the change of bracelet themselves and send their watch back to the shop or factory to have the bracelet changed, with the associated cost and inconvenience.
Pour pallier ces désagréments, divers systèmes de fixation alternatifs ont également été proposés mais le plus souvent étant plus complexes structurellement, donc plus délicats à manipuler pour l’utilisateur ou alors plus simples et moins fiables. Divers exemples sont par exemples proposés à titre indicatif dans les brevetsTo overcome these inconveniences, various alternative fastening systems have also been proposed but more often than not being more complex structurally, therefore more delicate to handle for the user or more simple and less reliable. Various examples are for example offered as an indication in patents
CH 707056 A2, EP 2229836 ou EP3266335. CH 707056 A2, EP 2229836 or EP3266335.
Le but de la présente invention est par conséquent de procurer un nouveau système de fixation, notamment de brins de bracelet pour des montres ou pièces de joaillerie qui procure une fiabilité analogue au système connue de fixation par barrettes mais en étant plus simple à manipuler pour l’utilisateur afin de permettre un changement de bracelet facilité, sans altération dudit bracelet ou de la montre ou pièce de joaillerie. The object of the present invention is therefore to provide a new fixing system, in particular bracelet strands for watches or pieces of jewelry which provides reliability similar to the known system of fixing by bars but being easier to handle for the user to allow easy bracelet change, without altering said bracelet or the watch or piece of jewelry.
Un but additionnel de la présente invention est de procurer un dit système de fixation permettant de changer un bracelet manuellement et sans outil particulier. Divulgation de l’invention An additional object of the present invention is to provide a said fixing system making it possible to change a bracelet manually and without any particular tool.

- la figure 1 représente une vue de dessus d’un élément de liaison selon la présente invention, - Figure 1 shows a top view of a connecting element according to the present invention,
- la figure 2 représente une vue de droite de l’élément de liaison de la figure 1. - Figure 2 shows a right view of the connecting element of Figure 1.
Mode de réalisation de l’invention Embodiment of the invention
On a représenté sur les figures 1 et 2 un élément de liaison 1 conforme à la présente invention dans un mode préféré de réalisation. Cet élément de liaison 1 peut avantageusement être utilisé pour permettre une fixation réversible, sans outils, d’un brin de bracelet sur une pièce de joaillerie ou d’une pièce d’horlogerie comportant en guise d’ancrage du brin de bracelet une barrette de fixation, amovible ou non, de ladite pièce de joaillerie ou d’une pièce d’horlogerie. Une application privilégiée de l’invention peut notamment être comme dernier maillon d’un brin de bracelet de montre, ou comme insert de connexion intégré à un brin de bracelet synthétique, textile ou de cuir, afin de fixer de manière réversible ce brin sur la barrette classique de la montre entre les cornes de la boite de montre. There is shown in Figures 1 and 2 a connecting element 1 according to the present invention in a preferred embodiment. This connecting element 1 can advantageously be used to allow a reversible attachment, without tools, of a bracelet strand to a piece of jewelry or of a timepiece comprising, by way of anchoring the bracelet strand, a bar of attachment, removable or not, of said piece of jewelry or of a timepiece. A preferred application of the invention can in particular be as the last link of a strand of a watch strap, or as a connection insert integrated into a strand of synthetic, textile or leather strap, in order to fix this strand reversibly on the classic bar of the watch between the horns of the watch case.
L’élément de liaison 1 de l’invention représenté sur les figures 1 et 2 correspond à titre d’exemple à un maillon de bracelet et se compose essentiellement d’un corps 11 , de forme générale sensiblement parallélépipédique, sur une première face principale duquel est formée une rainure 12 s’étendant suivant un plan incliné P, par exemple sensiblement à 45° par rapport à un plan longitudinal médian M dans le corps 11 de l’élément 1 , de manière à former à une extrémité du corps 11 un crochet 13, adapté pour réaliser le passage de l’élément de liaison 1 sur une barrette de fixation solidaire d’un objet auquel raccorder le brin de bracelet, tel qu’une boite de montre-bracelet. De façon avantageuse, la réalisation de la rainure 12 suivant un plan incliné P permet de procurer un plan de guidage G d’une dite barrette vers le fond de rainure dans le creux du crochet 13, lequel est situé de préférence sensiblement au point d’intersection des plans P et M, de telle sorte que l’élément de liaison 1 soit libre en rotation et en équilibre sous son propre poids sur la barrette une fois la barrette insérée au fond de la rainure 12. En pratique, la profondeur de la rainure est réalisée de telle sorte que lorsque une dite barrette est insérée dans la rainure 12 et libre en rotation sous son poids, celle-ci n’est en appui que sur le corps de l’élément de liaison 1 , à l’exclusion de tout contact avec le clapet 14. The connecting element 1 of the invention shown in Figures 1 and 2 corresponds by way of example to a bracelet link and essentially consists of a body 11, of generally substantially parallelepiped shape, on a first main face of which is formed a groove 12 extending along an inclined plane P, for example substantially at 45 ° relative to a median longitudinal plane M in the body 11 of the element 1, so as to form at one end of the body 11 a hook 13, suitable for carrying out the passage of the connecting element 1 over a fixing bar secured to an object to which the bracelet strand is connected, such as a wristwatch box. Advantageously, the embodiment of the groove 12 along an inclined plane P provides a guide plane G of a said bar towards the bottom of the groove in the hollow of the hook 13, which is preferably located substantially at the point of intersection of the planes P and M, so that the connecting element 1 is free to rotate and to balance under its own weight on the bar once the bar is inserted at the bottom of the groove 12. In practice , the depth of the groove is made so that when a said bar is inserted into the groove 12 and free to rotate under its weight, the latter is only supported on the body of the connecting element 1, excluding any contact with the valve 14.
L’élément de liaison 1 de l’invention comporte également un clapet 14 de maintien monté mobile en rotation à l’extrémité du crochet 13, par exemple sur deux plots formant axe de rotation ou autour d’une tige T insérée dans des orifices prévus à cet effet dans des pattes 131 , 141 du crochet 13 et du clapet 14 respectivement. Le clapet 14 est ainsi mobile sur le corps 11 de l’élément de liaison entre une position d’ouverture dans laquelle une dite barrette peut être insérée dans la rainure 12 du crochet 13 et une position de fermeture dans laquelle ledit clapet 14 empêche toute sortie d’une dite barrette de ladite rainure 12, maintenant ainsi ledit élément de liaison sur la dite barrette, libre en rotation. The connecting element 1 of the invention also comprises a retaining valve 14 mounted movable in rotation at the end of the hook 13, for example on two studs forming an axis of rotation or around a rod T inserted in the orifices provided for this purpose in the legs 131, 141 of the hook 13 and the valve 14 respectively. The valve 14 is thus movable on the body 11 of the connecting element between an open position in which a said bar can be inserted in the groove 12 of the hook 13 and a closed position in which said valve 14 prevents any exit of a said bar of said groove 12, thus maintaining said connecting element on said bar, free to rotate.
Conformément à la présente invention, l’élément de liaison 1 comporte en outre des moyens de verrouillage du clapet 14 en position de fermeture. Dans la forme de réalisation représentée, ces moyens de verrouillage comportant une portée cylindrique 15 disposée sur le corps 11 , au niveau de la surface de raccordement entre le plan incliné de guidage G et la surface principale du corps 11 dans lequel la rainure 12 est formée, et une dent 16 formée sur un bord longitudinal d’une ouverture 17 percée dans le clapet 14 According to the present invention, the connecting element 1 further comprises means for locking the valve 14 in the closed position. In the embodiment shown, these locking means comprising a cylindrical surface 15 disposed on the body 11, at the level of the connection surface between the inclined guide plane G and the main surface of the body 11 in which the groove 12 is formed , and a tooth 16 formed on a longitudinal edge of an opening 17 drilled in the valve 14
La portée cylindrique 15 est de préférence constituée d’un rouleau 151 logé au moins partiellement dans une creusure ou réservation sur le corps 11 et pivotant sur un axe 18 fixé en ses extrémités opposées dans des orifices (non représentés sur les figures) formés à cet effet dans le corps 11 , par exemple dans des cornes ou pattes formées de matière dans le corps 11 de l’élément de liaison. The cylindrical bearing surface 15 preferably consists of a roller 151 housed at least partially in a recess or reservation on the body 11 and pivoting on an axis 18 fixed at its opposite ends in orifices (not shown in the figures) formed at this effect in the body 11, for example in horns or lugs formed of material in the body 11 of the connecting element.
La dent 16 est de préférence formée saillante dans l’ouverture 17 du clapet 14 de telle sorte qu’elle appuie sur le rouleau 151 et subisse une légère déformation élastique en flexion lors de la fermeture et l’ouverture du clapet, cette déformation étant maximale au passage de la dent au point d’alignement de l’axe longitudinal de la dent avec le rayon du rouleau 151. Une fois ce point dépassé par la dent 16, elle reprend sa forme normale par élasticité, opérant la fermeture du clapet avec un blocage de la dent et donc du clapet en appui contre la base du rouleau 151 , alors que le clapet repose en appui sur le corps 11 de l’élément dans la position de fermeture. Le blocage de la dent 16 et du clapet 14 ne peut ensuite être libéré que par un effort manuel de traction d’un utilisateur sur le clapet, par exemple à l’aide d’un ongle contre une encoche 19 d’ouverture formée à l’extrémité libre du clapet 14 ou sur le corps 11 , pour faire passer à nouveau le clapet 14 par-dessus le rouleau 151 dans un sens inverse d’ouverture, dégageant ainsi l’accès à la rainure 12 et permettant le retrait de l’élément de liaison autour de la barrette sur laquelle il était passé. The tooth 16 is preferably formed projecting into the opening 17 of the valve 14 so that it presses on the roller 151 and undergoes a slight elastic deformation in bending during the closing and opening of the valve, this deformation being maximum at the passage of the tooth at the point of alignment of the longitudinal axis of the tooth with the radius of the roller 151. Once this point passed by the tooth 16, it resumes its normal shape by elasticity, operating the closure of the valve with a blocking of the tooth and therefore of the valve bearing against the base of the roller 151, while the valve rests on the body 11 of the element in the closed position. The blocking of the tooth 16 and of the valve 14 can then be released only by a manual effort of traction of a user on the valve, for example using a nail against an opening notch 19 formed at the free end of the valve 14 or on the body 11, to again pass the valve 14 over the roller 151 in an opposite direction of opening, thereby freeing access to the groove 12 and allowing the withdrawal of the connecting element around the bar on which it had passed.
L’élément de liaison 1 comporte par ailleurs dans l’exemple représenté sur les figures un orifice transversal 20 de passage d’un axe de liaison ou une barrette à un maillon de brin de bracelet. En variante à cet orifice, ledit axe de liaison peut être formé dans la masse du corps 11 , sous la forme de tétons latéraux s’étendant parallèlement à l’axe de rotation du clapet. The connecting element 1 also comprises in the example shown in the figures a transverse orifice 20 for passage of a connecting pin or a bar to a bracelet strand link. As a variant to this orifice, said connecting axis can be formed in the mass of the body 11, in the form of lateral pins extending parallel to the axis of rotation of the valve.
Par ailleurs dans une variante non représentée, l’élément de liaison 1 peut également comporter, solidaire du corps 11 de l’élément de liaison un organe d’ancrage dans un brin de bracelet de matière synthétique ou naturelle, notamment de matières plastiques, de caoutchouc ou de cuir, ou encore de textile synthétique ou naturel. Un tel organe d’ancrage peut être en forme de plaquette ou analogue venue de matière sur le corps 11 , et étant adaptée pour être inséré par surmoulage, vulcanisation, dans un brin de matière synthétique ou de caoutchouc, ou encore surpiqué ou collé dans un brin de bracelet textile ou de cuir, l’élément de liaison formant alors un insert dans un tel brin. Furthermore, in a variant not shown, the connecting element 1 can also comprise, integral with the body 11 of the connecting element, an anchoring member in a bracelet strand of synthetic or natural material, in particular of plastics, rubber or leather, or synthetic or natural textile. Such an anchoring member may be in the form of a plate or the like made of material on the body 11, and being adapted to be inserted by overmolding, vulcanization, in a strand of synthetic material or rubber, or even overstitched or glued in a strand of textile or leather bracelet, the connecting element then forming an insert in such a strand.
L’élément de liaison 1 de l’invention présente ainsi une forme et structure très simple et facile à réaliser, que ce soit dans des matériaux métalliques tels que l’acier, ou des métaux précieux tels que or, argent ou titane, ou encore en matière synthétique par moulage et assemblage de pièces injectées. Il convient par ailleurs de noter que bien que dans le mode de réalisation représenté la portée cylindrique 15 et la dent 16 de verrouillage du clapet aient été respectivement présentées sur le corps 11 de l’élément 1 et le clapet 14 de maintien il serait possible d’inverser la disposition de ces éléments pour procurer la portée cylindrique 15 dans une ouverture ou un rebord du clapet 14 alors que la dent 16 est agencée sur le corps 11 de l’élément, selon des principes et une efficacité de verrouillage analogues à celle de la réalisation décrite et représentée. The connecting element 1 of the invention thus has a very simple shape and structure and easy to produce, whether in metallic materials such as steel, or in precious metals such as gold, silver or titanium, or else made of synthetic material by molding and assembly of injected parts. It should also be noted that although in the embodiment shown the cylindrical surface 15 and the tooth 16 for locking the valve have been respectively presented on the body 11 of the element 1 and the valve 14 for holding it would be possible to 'reverse the arrangement of these elements to provide the cylindrical seat 15 in an opening or a flange of the valve 14 while the tooth 16 is arranged on the body 11 of the element, according to principles and locking efficiency similar to that of the embodiment described and shown.
Cet élément de liaison 1 procure une solution avantageuse de fixation d’un brin de bracelet sur une barrette montée sur une pièce de joaillerie ou d’horlogerie, que ce soit de série ou en guise d’accessoire pour des bijoux ou montres-bracelet existantes, sans requérir d’outils et avec une grande sécurité de maintien. This connecting element 1 provides an advantageous solution for attaching a strand of bracelet to a bar mounted on a piece of jewelry or timepiece, either as standard or as an accessory for existing jewelry or wristwatches , without the need for tools and with a high level of security.
