Description

La présente invention se rapporte à un dispositif de liaison amovible d'un bracelet à une pièce, notamment une boîte de montre, à laquelle ce bracelet doit être attaché, notamment une boîte de montre, ce dispositif comprenant deux organes d'accrochage complémentaires solidaires, respectivement, des extrémités de liaison dudit bracelet et de ladite pièce. L'invention porte aussi sur une montre-bracelet comprenant un tel dispositif. L'invention porte encore sur une boîte de montre comportant un organe d'accrochage prévu pour coopérer avec un autre organe d'accrochage complémentaire. L'invention porte enfin sur un brin de bracelet comportant un organe d'accrochage prévu pour coopérer avec un autre organe d'accrochage complémentaire.The present invention relates to a removable connecting device for a one-piece bracelet, in particular a watch case, to which this bracelet must be attached, in particular a watch case, this device comprising two integral complementary attachment members, respectively, connecting ends of said bracelet and of said part. The invention also relates to a wristwatch comprising such a device. The invention also relates to a watch case comprising an attachment member provided to cooperate with another complementary attachment member. The invention finally relates to a bracelet strand comprising an attachment member provided to cooperate with another complementary attachment member.

La fixation la plus courante d'un bracelet entre les cornes d'une boîte de montre est réalisée à l'aide d'une barrette à ressort. Cette barrette comporte une cheville de fixation à chaque extrémité, une de ces chevilles étant solidaire d'un piston monté coulissant dans l'autre partie tubulaire de la barrette. Un ressort hélicoïdal monté dans la partie tubulaire sert à faire saillir la cheville hors du logement tubulaire. L'extrémité ouverte de la paroi tubulaire est légèrement déformée vers l'intérieur après introduction de piston pour empêcher que celui-ci ne puisse ressortir de la partie tubulaire.The most common attachment of a bracelet between the lugs of a watch case is made using a spring bar. This bar has a fixing pin at each end, one of these pins being secured to a piston mounted to slide in the other tubular part of the bar. A coil spring mounted in the tubular portion serves to protrude the pin out of the tubular housing. The open end of the tubular wall is slightly deformed inwards after introduction of the piston to prevent the latter from coming out of the tubular part.

La mise en place et l'enlèvement d'un bracelet à l'aide de ce mode de fixation nécessite l'utilisation d'outils pour faire rentrer et maintenir le piston dans la partie tubulaire. Une telle opération demande une certaine habileté. En outre, lorsque l'on est arrivé à introduire la barrette entre les cornes, il faut trouver le trou ménagé dans les cornes pour permettre au ressort d'y introduire cette cheville. Il s'agit donc d'une opération qui n'est pas à la portée de chacun.Putting on and removing a bracelet using this fastening method requires the use of tools to fit and hold the piston in the tubular part. Such an operation requires a certain skill. In addition, when we have managed to introduce the bar between the horns, it is necessary to find the hole made in the horns to allow the spring to introduce this ankle. It is therefore an operation that is not within everyone's reach.

Le document EP 1 219 199 A2 décrit un dispositif de fixation amovible d'un bracelet à une boîte de montre, ce dispositif comprenant les caractéristiques du préambule de la revendication indépendante 1 annexée.The document EP 1 219 199 A2 describes a device for removable fastening of a bracelet to a watch case, this device comprising the features of the preamble of the appended independent claim 1.

Le but de la présente invention est de remédier, au moins en partie aux inconvénients de ce mode de fixation et mettre l'opération de remplacement d'un bracelet à la portée de chacun.The object of the present invention is to remedy, at least in part, the drawbacks of this mode of attachment and to make the operation of replacing a bracelet within everyone's reach.

A cet effet, la présente invention a pour objet un dispositif de liaison amovible d'un bracelet à une pièce ou à un organe auquel ce bracelet doit être attaché, notamment une boîte de montre, tel que défini par la revendication 1. Des réalisations préférées sont définies dans les revendications dépendantes.To this end, the subject of the present invention is a removable device for connecting a bracelet to a part or to a member to which this bracelet must be attached, in particular a watch case, as defined by claim 1. Preferred embodiments are defined in the dependent claims.

Dans ce dispositif, les organes d'accrochage de ce dispositif sont dirigés selon une direction Z, transversalement à la direction X longitudinale du bracelet; l'un des organes d'accrochage est déplaçable latéralement, selon une direction Y, entre deux positions limites, une première position dans laquelle il est en prise avec l'autre des organes d'accrochage, une seconde position dans laquelle il est dissocié de cet autre organe d'accrochage. Des moyens de rappel élastiques tendent à maintenir l'organe d'accrochage déplaçable latéralement entre deux positions limites dans sa première position.In this device, the attachment members of this device are directed in a direction Z, transversely to the longitudinal direction X of the bracelet; one of the attachment members can be moved laterally, in a direction Y, between two limit positions, a first position in which it engages with the other of the attachment members, a second position in which it is dissociated from this other attachment member. Elastic return means tend to hold the laterally displaceable attachment member between two limit positions in its first position.

De préférence, la boîte de montre, comporte un siège pour un élément de butée amovible et des moyens de fixation de cet élément de butée sur ce siège, cet élément de butée amovible définissant la première position limite de l'organe d'accrochage déplaçable entre deux positions limites.Preferably, the watch case comprises a seat for a removable abutment element and means for fixing this abutment element to this seat, this removable abutment element defining the first limit position of the displaceable attachment member between two limit positions.

Selon l'invention, les organes d'accrochage comportent des éléments d'encliquetage pour permettre de provoquer le déplacement de l'organe d'accrochage déplaçable entre deux positions limites, à l'encontre de la pression desdits moyens rappel élastiques, de sa première à sa seconde position limite, lors de la mise en prise des deux organes d'accrochage dans un sens perpendiculaire à la direction transversale des organes d'accrochage.According to the invention, the attachment members comprise snap-fastening elements to make it possible to cause the movement of the attachment member movable between two limit positions, against the pressure of said return means elastic, from its first to its second limit position, when the engagement of the two attachment members in a direction perpendicular to the transverse direction of the attachment members.

Il est également avantageux que l'élément de butée amovible comporte une ouverture pour permettre d'accéder à l'organe d'accrochage déplaçable et de le déplacer à l'encontre des moyens de rappel élastique pour l'amener dans la seconde de ses positions limites.It is also advantageous for the removable abutment element to include an opening to allow access to the movable attachment member and to move it against the elastic return means to bring it into the second of its positions. boundaries.

Ce dispositif est simple et permet la mise en place et l'enlèvement du bracelet sans outil ni habileté particuliers et par chaque utilisateur.This device is simple and allows the installation and removal of the bracelet without special tools or skills and by each user.

Bien que la forme d'exécution illustrée qui sera décrite ci-après se rapporte à la liaison d'un bracelet à une montre, il est évident qu'un dispositif semblable peut être utilisé pour relier un bracelet à une autre pièce qu'une boîte de montre, tel qu'un fermoir, voire à une pièce de bijouterie.Although the illustrated embodiment which will be described below relates to the connection of a bracelet to a watch, it is obvious that a similar device can be used to connect a bracelet to a part other than a box watch, such as a clasp, or even a piece of jewelry.

Les figures 1 et 2 illustrent une boîte de montre 1, de chaque côté de laquelle une extrémité d'un brin de bracelet 2a, 2b est destinée à être reliée de façon amovible. Les figures 1 et 2 montrent une extrémité du brin de bracelet 2a reliée au côté gauche de la boîte de montre 1 et une extrémité du brin de bracelet 2b séparée du côté droit de la boîte de montre 1.THE figures 1 and 2 illustrate a watch case 1, on each side of which one end of a bracelet strand 2a, 2b is intended to be removably connected. THE figures 1 and 2 show one end of bracelet strand 2a connected to the left side of watchcase 1 and one end of bracelet strand 2b separated from the right side of watchcase 1.

Le dispositif de liaison objet de l'invention est illustré par la figure 4 et les deux organes d'accrochage complémentaires 3 et 4 sont illustrés séparément par les figures 5A, 5B, respectivement 6A, 6B. L'organe d'accrochage 4 est destiné à s'insérer dans une des extrémités des brins de bracelets 2a, 2b, comme illustré par les figures 1A, 1B, 2A, 2B et 4. L'organe d'accrochage 3 comporte un élément d'accrochage 3a divisé en deux par un élément de poussoir comprenant une tête 3b et une tige 3c. La face inférieure de cette tige 3c présente un logement cylindrique 3d (figure 5B) pour recevoir un ressort de rappel 5 (figure 4). Une douille 6 est destinée à être fixée dans une ouverture ménagée dans le fond d'un logement rectangulaire 7 ménagé dans l'entre-corne de la boîte de montre 1. Ce logement rectangulaire est destiné à recevoir l'élément d'accrochage 3a et à le positionner, par exemple selon la direction Z, transversalement à la direction longitudinale X du bracelet 2a, 2b. Le ressort de rappel 5, comprimé entre le fond de la douille 6 et le fond du logement 3d ménagé dans la tige de poussoir 3c, sert à pousser l'organe d'accrochage 3 vers l'extérieur de la carrure de boîte 1.The connecting device which is the subject of the invention is illustrated by the figure 4 and the two complementary attachment members 3 and 4 are illustrated separately by the Figures 5A, 5B , respectively 6A, 6B. The attachment member 4 is intended to be inserted into one of the ends of the bracelet strands 2a, 2b, as illustrated by the figures 1A, 1B, 2A, 2B and 4 . The attachment member 3 comprises an attachment element 3a divided in two by a pusher element comprising a head 3b and a rod 3c. The underside of this rod 3c has a cylindrical housing 3d ( figure 5B ) to receive a return spring 5 ( figure 4 ). A socket 6 is intended to be fixed in an opening made in the bottom of a rectangular housing 7 made in the inter-horn of the watch case 1. This rectangular housing is intended to receive the attachment element 3a and to position it, for example in the direction Z, transversely to the longitudinal direction X of the bracelet 2a, 2b. The return spring 5, compressed between the bottom of the sleeve 6 and the bottom of the housing 3d formed in the push rod 3c, serves to push the attachment member 3 towards the outside of the case middle 1.

Pour limiter la course de l'organe d'accrochage 3, la tête 3b du poussoir comporte deux portées latérales 3e. Ces portées sont destinées à venir appuyer contre deux bords opposés d'une ouverture rectangulaire 8a d'un organe de butée 8 (figure 4) sous la pression du ressort de rappel 5. Cet organe de butée 8 est conformé pour se loger sur un siège 10 situé dans l'entre-corne de la boîte 1 et est fixé par deux vis 9 sur ce siège de la boîte de montre 1.To limit the stroke of the attachment member 3, the head 3b of the pusher has two lateral bearing surfaces 3e. These bearing surfaces are intended to bear against two opposite edges of a rectangular opening 8a of an abutment member 8 ( figure 4 ) under the pressure of the return spring 5. This abutment member 8 is shaped to be housed on a seat 10 located in the between-lug of the case 1 and is fixed by two screws 9 on this seat of the watch case 1.

Un organe d'accrochage 4 est inséré à une extrémité de chaque brin de bracelet 2a, 2b. Cet organe d'accrochage 4 comporte un élément d'accrochage 4a disposé transversalement au bracelet 2, par exemple selon la direction Z et divisé en deux parties par un passage 4b pour recevoir la tige 3c du poussoir de l'organe d'accrochage 3 lors de l'accrochage de l'élément d'accrochage sur l'élément d'accrochage 3. Pour permettre cet assemblage des deux organes d'accrochage 3 et 4, l'organe d'accrochage comporte un logement transversal 4c (figure 6B). Pour faciliter l'assemblage et le rendre automatique suite à une simple poussée exercée dans la direction longitudinale du bracelet 2 en direction de la boîte 1, les faces d'engagement 3f, 4f, de l'organe d'accrochage 3, respectivement de l'organe d'accrochage 4 sont biseautées, formant ainsi un assemblage par encliquetage, permettant l'assemblage dans un sens et empêchant la séparation dans le sens inverse.A hooking member 4 is inserted at one end of each bracelet strand 2a, 2b. This attachment member 4 comprises an attachment element 4a arranged transversely to the bracelet 2, for example in the direction Z and divided into two parts by a passage 4b to receive the rod 3c of the pusher of the attachment member 3 when the attachment of the attachment element on the attachment element 3. To allow this assembly of the two attachment members 3 and 4, the attachment member comprises a transverse housing 4c ( figure 6B ). To facilitate assembly and make it automatic following a simple push exerted in the longitudinal direction of the bracelet 2 in the direction of the case 1, the engagement faces 3f, 4f, of the attachment member 3, respectively of the hooking member 4 are bevelled, thus forming a snap-fit assembly, allowing assembly in one direction and preventing separation in the opposite direction.

En effet, la séparation ne peut être obtenue qu'en exerçant une pression sur la tête 3b du poussoir pour déplacer, notamment déplacer latéralement selon la direction Y, l'organe d'assemblage 3 à l'encontre de la pression du ressort de rappel 6, comme illustré par la figure 2B. De préférence, la tête 3b du poussoir est noyée dans l'épaisseur de la planche de l'organe de butée 8 pour que l'on ne puisse pas actionner le poussoir par inadvertance. Dans ce cas une simple pointe de stylo à bille par exemple permet d'actionner la tête 3b du poussoir pour dégager l'élément d'assemblage 3a du logement 4c et de l'élément d'assemblage 4a de l'organe d'assemblage 4.Indeed, the separation can only be obtained by exerting pressure on the head 3b of the pusher to move, in particular to move laterally in the direction Y, the assembly member 3 against the pressure of the return spring 6, as illustrated by figure 2B . Preferably, the head 3b of the pusher is embedded in the thickness of the board of the abutment member 8 so that the pusher cannot be actuated inadvertently. In this case, a simple tip of a ballpoint pen, for example, makes it possible to actuate the head 3b of the pusher to disengage the assembly element 3a from the housing 4c and from the assembly element 4a of the assembly member 4 .

Grâce à la conception de ce dispositif de liaison, l'utilisateur n'a pas à enlever l'organe de butée 8. Celui-ci est mis en place à l'usine, de même que l'organe d'accrochage 3 et son ressort de rappel. La seule intervention que l'utilisateur est appelé à faire est de presser le poussoir 3b lorsqu'il veut enlever le bracelet. Pour remettre le bracelet, une simple poussée dans l'axe longitudinal du bracelet en direction de la boîte de montre 1 est suffisante, puisque les organes d'accrochage sont assemblés par encliquetage. Outre sa simplicité de conception et d'utilisation, le dispositif de liaison objet de l'invention offre des garanties de sécurité comparables à une fixation classique par barrette.Thanks to the design of this connecting device, the user does not have to remove the abutment member 8. This is fitted at the factory, as are the attachment member 3 and its spring. The only intervention that the user is required to do is to press the pusher 3b when he wants to remove the bracelet. To replace the bracelet, a simple push in the longitudinal axis of the bracelet in the direction of the watchcase 1 is sufficient, since the attachment members are assembled by snap-fastening. In addition to its simplicity of design and use, the connecting device which is the subject of the invention offers security guarantees comparable to a conventional fixing by bar.

Dans le mode de réalisation décrit plus haut, les axes X, Y et Z sont perpendiculaires deux à deux. Dans d'autres modes de réalisation, ces axes ne sont pas nécessairement perpendiculaires. Ils peuvent aussi être sensiblement perpendiculaires. En particulier, les axes X et Y ne sont pas nécessairement perpendiculaires.In the embodiment described above, the axes X, Y and Z are perpendicular in pairs. In other embodiments, these axes are not necessarily perpendicular. They can also be substantially perpendicular. In particular, the X and Y axes are not necessarily perpendicular.

Dans un mode de réalisation, la boîte de montre, comprend le premier organe d'accrochage 3 destiné à coopérer avec le deuxième organe d'accrochage 4 prévu sur un brin de bracelet, lequel comprend le deuxième organe d'accrochage destiné à coopérer avec le premier organe d'accrochage prévu sur la boîte de montre.In one embodiment, the watch case comprises the first attachment member 3 intended to cooperate with the second attachment member 4 provided on a strand of bracelet, which comprises the second attachment member intended to cooperate with the first attachment member provided on the watch case.

Dans un autre mode de réalisation, un brin de bracelet, comprend le premier organe d'accrochage destiné à coopérer avec le deuxième organe d'accrochage prévu sur la boîte de montre, laquelle le deuxième organe d'accrochage destiné à coopérer avec le premier organe d'accrochage prévu sur le brin de bracelet.In another embodiment, a bracelet strand comprises the first attachment member intended to cooperate with the second attachment member provided on the watch case, which the second attachment member intended to cooperate with the first member hooking provided on the bracelet strand.
