Description

DOMAINE TECHNIQUE ET ETAT DE LA TECHNIQUETECHNICAL FIELD AND STATE OF THE ART

La présente invention concerne notamment, mais de façon non-exclusive, le domaine des montres et des parties de montres.The present invention relates in particular, but non-exclusively, the field of watches and parts of watches.

Plus particulièrement, la présente invention concerne un système de fixation permettant d'attacher de façon amovible un bracelet à une montre. Bien entendu, la présente invention n'est pas limitée au domaine des montres et peut s'appliquer dans d'autres domaines, par exemple pour la fixation d'une lanière à un sac, d'une boucle sur une ceinture etc.More particularly, the present invention relates to a fastening system for removably attaching a bracelet to a watch. Of course, the present invention is not limited to the field of watches and can be applied in other areas, for example for fixing a strap to a bag, a buckle on a belt etc.

De façon classique, les bracelets de montre sont attachés au boîtier de ladite montre au moyen de barrettes qui comprennent un corps tubulaire contenant un ressort et deux goupilles placées à chaque extrémité dudit corps tubulaire, lesdites goupilles étant poussées vers l'extérieur par le ressort. Pour la fixation proprement dite du bracelet, chaque goupille est insérée dans un canal du bracelet et s'emboîte dans un trou formé dans les cornes du boîtier de la montre.Conventionally, the watch straps are attached to the case of said watch by means of bars which comprise a tubular body containing a spring and two pins placed at each end of said tubular body, said pins being pushed outwards by the spring. For the actual fixing of the bracelet, each pin is inserted into a channel of the bracelet and fits into a hole formed in the horns of the watch case.

Lorsque l'utilisateur souhaite changer de bracelet (soit parce que le bracelet actuel est usé/abîmé ou s'il en possède plusieurs différents et qu'il souhaite l'adapter à sa tenue par exemple), le déboîtage des deux goupilles de la barrette hors des cornes n'est pas facile et nécessite de préférence un outil particulier.When the user wishes to change the bracelet (either because the current bracelet is worn / damaged or if it has several different and he wants to adapt to its behavior for example), the removal of the two pins of the bar off the horns is not easy and preferably requires a particular tool.

De plus, lors du montage d'un bracelet, les goupilles de la barrette qui sont poussées par le ressort ont tendance à rayer la face interne des cornes tant qu'elles ne sont pas entrées dans le trou correspondant de la corne, un effet qui n'est pas du tout désiré avec des montres de prix élevé ou de collection dont on veut éviter tout endommagement.In addition, when mounting a bracelet, the pins of the bar which are pushed by the spring tend to scratch the inner face of the horns as they have not entered the corresponding hole of the horn, an effect that is not desired at all with expensive watches or collectibles that we want to avoid any damage.

Ainsi, si les moyens actuels ont l'avantage de la simplicité, ils possèdent de nombreux désavantages à l'usage.Thus, if the current means have the advantage of simplicity, they have many disadvantages to use.

Dans l'état de la technique, plusieurs dispositifs ont été développés comme moyens de remplacement de la barrette. Par exemple, la publication EP 1 772 072 de Hirsch Armbänder GmbH montre un premier système de goupilles actionnées par des moyens pivotants qui sont engrenés l'un dans l'autre. Le mouvement de pivotement de l'un entraîne le pivotement de l'autre et par ce pivotement des moyens les goupilles sont entraînées en position rétractée ou en position déployée pour la fixation du bracelet au boîtier de montre. Ce système est néanmoins rigide et les deux goupilles sont entraînées en ensemble de façon dépendante. En conséquence, si l'une des goupilles n'est pas en face du trou correspondant de la corne, le système connu se bloque et ne permet pas la fixation d'une des goupilles indépendamment de l'autre. De plus si l'une des goupilles est en face de son trou mais pas l'autre, le mouvement coordonné des goupilles va rayer l'intérieur de la corne du côté ou la goupille "cherche" son trou, un effet que l'on veut justement éviter. Ainsi, la solution proposée par cette publication n'est pas appropriée.In the state of the art, several devices have been developed as means for replacing the bar. For example, the publication EP 1 772 072 from Hirsch Armbänder GmbH shows a first system of pins actuated by pivoting means which are engaged with each other. The pivoting movement of one drives the pivoting of the other and by this pivoting means the pins are driven in the retracted position or in the extended position for attachment of the bracelet to the watch case. This system is nevertheless rigid and the two pins are driven together in a dependent manner. Accordingly, if one of the pins is not in front of the corresponding hole of the horn, the known system is blocked and does not allow the attachment of one of the pins independently of the other. Moreover, if one of the pins is in front of its hole but not the other, the coordinated movement of the pins will scratch the inside of the horn on the side where the pin "seeks" its hole, an effect that one just wants to avoid. Thus, the solution proposed by this publication is not appropriate.

La publication FR 2 445 120 de Timex Corporation décrit un autre système de fixation amovible pour montres-bracelets. Cette solution comprend deux éléments pivotants sur lesquels sont montés directement des goupilles destinées à s'emboîter dans les trous des cornes du boîtier de la montre. Du fait du montage des goupilles sur des éléments pivotants, toute traction sur le bracelet aura tendance à déplacer les éléments dans leur position déboîtée ou désengagée ce qui va libérer le bracelet, un effet qui n'est évidemment pas souhaité. En conséquence, il est nécessaire de prévoir en plus un verrou qui bloquera les éléments pivotants en position déployées, ce verrou étant complexe à mettre en oeuvre puisqu'il faut prévoir son déverrouillage volontaire (lorsqu'il est souhaité).The publication FR 2,445,120 from Timex Corporation describes another detachable fastening system for wristwatches. This solution comprises two pivoting elements on which are directly mounted pins for fitting into the holes of the horns of the watch case. Because of the mounting of the pins on pivoting elements, any traction on the bracelet will tend to move the elements in their disengaged or disengaged position which will release the bracelet, an effect that is obviously not desired. Consequently, it is necessary to provide in addition a lock which will block the pivoting elements in the deployed position, this lock being complex to implement since it must provide for its voluntary unlocking (when desired).

La publication FR 2 988 271 de la société Interstrap SAS décrit un autre système de verrouillage d'une pièce amovible interchangeable (par exemple un bracelet) à une pièce fixe (par exemple un boîtier de montre) utilisant des goupilles dont le déplacement est commandé par des bras de liaison déformables élastiquement et guidés, convergeant symétriquement vers un corps central qui est actionné par un organe de commande externe. Cette solution est compliquée car comprenant de nombreuses petites pièces et possède un gros point faible dans l'utilisation des bras de liaison déformables.The publication FR 2 988 271 of the company Interstrap SAS describes another locking system of an interchangeable removable part (for example a bracelet) to a fixed part (for example a watch case) using pins whose displacement is controlled by elastically deformable connecting arms and guided, converging symmetrically to a central body which is actuated by an external control member. This solution is complicated because it includes many small parts and has a large weakness in the use of deformable link arms.

La publication Fr 2 287 187 de Claude Lafon montre une attache automatique pour bracelet-montre. Cette attache comprend notamment une languette de forme complexe avec deux parties: une première partie rectiligne destinée à rester sous une doublure du bracelet et dont la longueur est telle que son extrémité libre, constituant celle de la languette, ne peut pas être prisonnière de la cage, et une seconde partie qui, intercalée entre la première partie et la platine, constitue la base de la languette, présente la forme d'un pontet, est plus courte que la première partie et est destinée à chevaucher la doublure pour la retenir en cas de décollage accidentel.The publication Fr 2,287,187 of Claude Lafon shows an automatic fastener for wristwatch. This fastener comprises in particular a tongue of complex shape with two parts: a first straight part intended to remain under a lining of the bracelet and whose length is such that its free end, constituting that of the tongue, can not be trapped in the cage , and a second part which, sandwiched between the first part and the plate, constitutes the base of the tongue, has the shape of a bridge, is shorter than the first part and is intended to overlap the lining to retain it in case accidental takeoff.

La construction décrite ne comprend pas de moyen d'actionnement de la languette, ladite languette est d'une forme compliquée avec plusieurs zones de pliage ce qui complique sa construction et l'extrémité de la languette est recouverte de la doublure du bracelet ce qui augmente son épaisseur et par voie de conséquence l'épaisseur du système de fixation.The construction described does not include means for actuating the tongue, said tongue is of a complicated shape with several folding zones which complicates its construction and the end of the tongue is covered with the lining of the bracelet which increases its thickness and consequently the thickness of the fastening system.

De plus, la fermeture du système est assurée par la doublure du bracelet et non pas par la languette elle-même de sorte que, d'une part, une telle doublure est nécessaire, le positionnement de la languette par rapport à la doublure est critique lors de la fabrication pour assurer la fermeture et, d'autre part, la matière de la doublure doit être suffisamment rigide pour assurer cette fermeture ce qui peut nuire, par exemple, au confort du porteur de la montre-bracelet. Cette construction est donc très complexe et impose des ajustements très précis.In addition, the closure of the system is provided by the lining of the bracelet and not by the tongue itself so that, on the one hand, such a lining is necessary, the positioning of the tongue relative to the lining is critical during manufacture to ensure the closure and, secondly, the material of the lining must be rigid enough to ensure this closure which can affect, for example, the comfort of the wearer of the wristwatch. This construction is very complex and requires very precise adjustments.

La publication FR 2 207 665 de Claude Lafond illustre un mousqueton pour bracelet-montre. Ce mousqueton est constitué par une lame métallique découpée et cambrée pour constituer une plaquette évidée dont l'une des extrémités est repliée sur elle-même pour former une cage, évidée au moins à son extrémité libre, l'autre extrémité de la lame étant solidaire d'une languette ressort ayant son extrémité recourbée pour former un crochet qui, se logeant dans la cage évidée, est apte à emprisonner la doublure du bracelet, après que la plaquette ait été introduite entre les faces encollées en vis-à-vis de cette doublure et du cuir du bracelet, et à l'entraîner dans le mouvement transversal auquel elle est soumise lors de l'ouverture et de la fermeture du mousqueton tandis que l'extrémité évidée de la cage est contournée par l'extrémité du cuir du bracelet préalablement biseautée et encollée.The publication FR 2,207,665 to Claude Lafond illustrates a carabiner for wristwatch. This carabiner is constituted by a metal blade cut and arched to form a recessed wafer whose one end is folded on itself to form a cage, recessed at least at its free end, the other end of the blade being secured a spring tongue having its end curved to form a hook which, being housed in the recessed cage, is able to trap the lining of the bracelet, after the wafer has been introduced between the faces glued in vis-à-vis this lining and leather of the bracelet, and to train it in the transverse movement to which it is subjected when opening and closing the carabiner while the hollowed end of the cage is bypassed by the end of the leather of the bracelet previously bevelled and glued.

Le système connu de cette publication ne comprend pas de moyen d'actionnement du mousqueton qui comprend la lame métallique ayant une forme complexe à fabriquer (découpes, pliures). De plus, la lame est entièrement recouverte par le bracelet et la doublure du bracelet ce qui augmente l'épaisseur du système.The known system of this publication does not include means for actuating the carabiner which comprises the metal blade having a complex shape to manufacture (blanks, folds). In addition, the blade is completely covered by the bracelet and the lining of the bracelet which increases the thickness of the system.

Le brevet CH 518 697 de la société Oméga Louis Brandt & Frères décrit un bracelet de montre, qui est constitué par une bande en matière synthétique souple dont l'extrémité destinée à être fixée à une barrette de boîte de montre présente une échancrure dont la largeur est suffisante pour laisser passer la barrette de façon à permettre l'assemblage du bracelet à la barrette sans l'emploi d'aucun outil. Ce bracelet est caractérisé en ce que l'extrémité de la bande est renforcée par une armature intérieure, faite en une matière plus dure que la bande, ladite armature présentant une échancrure dont la forme correspond sensiblement à celle de l'échancrure de la bande, le tout de façon que la barrette soit maintenue par friction au fond de l'échancrure de la bande sans risque de séparation intempestive du bracelet et de la barrette.The patent CH 518 697 of the company Omega Louis Brandt & Frères describes a watch strap, which is constituted by a strip of flexible synthetic material whose end intended to be fixed to a bar of a watch case has a notch whose width is sufficient to pass the bar so as to allow the assembly of the bracelet to the bar without the use of any tool. This bracelet is characterized in that the end of the band is reinforced by an inner frame, made of a material harder than the band, said frame having a notch whose shape corresponds substantially to that of the notch of the band, all so that the bar is held by friction at the bottom of the notch of the band without risk of inadvertent separation of the bracelet and the bar.

Si le système décrit est très simple, il présente le défaut notable que toute traction sur la bande du bracelet va ouvrir l'échancrure de l'armature et par conséquent diminuer voire supprimer le maintien par friction de la barrette au fond de l'échancrure, ce qui aura pour résultat la désolidarisation du bracelet et du boîtier de la montre et l'ouverture du bracelet. Un fonctionnement et évidemment à éviter si le porteur ne veut pas que sa montre ne tombe ou soit perdue.If the system described is very simple, it has the notable defect that any traction on the band of the bracelet will open the notch of the armature and therefore reduce or eliminate the maintenance by friction of the bar at the bottom of the notch, which will result in the disconnection of the bracelet and the case of the watch and the opening of the bracelet. Operation and obviously to avoid if the wearer does not want his watch falls or be lost.

Au vu de ce qui précède, il existe un besoin de proposer des solutions qui surmontent les défauts des dispositifs connus et sont simples et faciles à mettre en oeuvre.In view of the above, there is a need to provide solutions that overcome the defects of known devices and are simple and easy to implement.

SOMMAIRE DE L'INVENTIONSUMMARY OF THE INVENTION

Un but de l'invention est d'améliorer les solutions connues de l'état de la technique.An object of the invention is to improve the known solutions of the state of the art.

Un autre but de l'invention est de proposer un système de fixation d'un élément amovible et interchangeable (par exemple un bracelet de montre) à un élément fixe (par exemple un boîtier de montre, ou plus précisément à la barrette du boîtier ou un axe remplaçant la barrette, ou encore à un élément équivalent d'une montre).Another object of the invention is to propose a system for fixing a removable and interchangeable element (for example a watch strap) to a fixed element (for example a watch case, or more precisely to the barrette of the case or an axis replacing the bar, or an equivalent element of a watch).

Un autre but de l'invention est de proposer une solution qui soit simple, efficace et facile à mettre en oeuvre et qui permette un échange facile d'un bracelet sur une montre, par exemple.Another object of the invention is to propose a solution that is simple, effective and easy to implement and that allows easy exchange of a bracelet on a watch, for example.

Un autre but de la présente invention est de proposer un système de fixation qui soit sûr et stable et de dimensions réduites pour son utilisation avec des bracelets fins.Another object of the present invention is to provide a fastening system which is safe and stable and of reduced dimensions for use with fine bracelets.

Dans un mode d'exécution, l'invention concerne donc un système de fixation d'un élément variable, comme un bracelet, à un objet fixe, comme un boîtier de montre d'une montre-bracelet qui permette un démontage et un changement faciles dudit bracelet, ne nécessitant ni l'emploi d'ongles ou d'outils.In one embodiment, the invention thus relates to a system for fixing a variable element, such as a bracelet, to a fixed object, such as a watch case of a wristwatch that allows easy disassembly and change. said bracelet, requiring neither the use of nails or tools.

Dans le cadre de l'application à la montre, par exemple la montre-bracelet, le système selon l'invention permet un échange rapide de bracelet par exemple pour monter un bracelet en cuir, ou en tissu ou en métal, ou caoutchouc (ou tout autre matière) en fonction de l'activité du porteur de la montre: par exemple, il peut décider d'utiliser un bracelet en cuir pour un effet "élégant" avec une tenue habillée, un bracelet en métal ou en tissu ou encore en matière synthétique pour des activités plus sportives, tout en conservant la même montre (c'est-à-dire le même boîtier). L'invention est particulièrement utile pour des montres d'un coût élevé mais aussi pour des montres bon-marché pour suivre des effets de mode.In the context of the application to the watch, for example the wristwatch, the system according to the invention allows a quick exchange of bracelet for example to mount a leather strap, or fabric or metal, or rubber (or any other material) according to the activity of the wearer of the watch: for example, he may decide to use a leather strap for an "elegant" effect with a dress, a metal or fabric bracelet or even synthetic material for more sporting activities, while keeping the same watch (ie the same case). The invention is particularly useful for high-cost watches but also for cheap watches to follow fashion effects.

Dans un mode d'exécution l'invention concerne un système de fixation d'un élément variable, comme un bracelet, à un objet fixe, comme un boîtier de montre, le système comprenant des moyens d'attache dudit élément variable sur l'objet fixe, les moyens d'attache comprenant une lame ressort et un moyen d'actionnement de la lame, ladite lame permettant de fermer le système de fixation.In one embodiment, the invention relates to a system for fixing a variable element, such as a bracelet, to a fixed object, such as a watch case, the system comprising means for attaching said variable element to the object. fixed, the fastening means comprising a spring blade and an actuating means of the blade, said blade for closing the fastening system.

Dans un mode d'exécution, le moyen d'actionnement est formé par un bouton ou par une forme de la lame, comme un bossage. Ceci permet par exemple une pression (par un doigt) sur le bouton/la lame et son déplacement par pliage de la lame dans l'insert. Le moyen d'actionnement peut également être formé d'un bouton et d'une partie particulière de la lame comme un bossage ou autre.In one embodiment, the actuating means is formed by a button or a shape of the blade, such as a boss. This allows for example a pressure (by a finger) on the button / blade and its displacement by folding the blade in the insert. The actuating means may also be formed of a button and a particular portion of the blade such as a boss or the like.

Dans un mode d'exécution, la lame comprend au moins une pliure pour limiter sa course. Ceci permet notamment de limiter l'épaisseur du système selon l'invention.In one embodiment, the blade comprises at least one fold to limit its stroke. This allows in particular to limit the thickness of the system according to the invention.

Dans un mode d'exécution, la lame comprend une deuxième pliure pour maintenir le moyen d'actionnement, comme le bouton, dans une position stable.In one embodiment, the blade includes a second fold to maintain the actuating means, such as the button, in a stable position.

Dans un mode d'exécution, les moyens d'attache comprennent en outre une rampe, par exemple pour le guidage de la barrette.In one embodiment, the attachment means further comprise a ramp, for example for guiding the bar.

Dans un mode d'exécution, les moyens d'attache comprennent un moyen élastique pour rattraper le jeu lorsque l'élément variable est attaché à l'élément fixe. Le moyen élastique peut être un ressort ou un autre moyen équivalent placé à un endroit approprié.In one embodiment, the attachment means comprises an elastic means for catching up the game when the variable element is attached to the fixed element.

DESCRIPTION DETAILLEEDETAILED DESCRIPTION

Selon le principe de l'invention, des moyens d'attache sont formés pour permettre un clipsage facile de l'élément variable sur l'élément fixe. Plus précisément, dans un mode d'exécution, des moyens de clipsage sont ajoutés sur les bracelets d'une montre afin de faciliter le changement de bracelet de ladite montre par un simple mouvement de clipsage.According to the principle of the invention, attachment means are formed to allow easy clipping of the variable element on the fixed element. More specifically, in one embodiment, clipping means are added to the wristbands of a watch to facilitate the wristwatch of said watch by a simple clipping movement.

Dans un premier mode d'exécution, illustré en figure 1, on a représenté une partie d'un bracelet 1 d'une montre, à savoir la partie du bracelet 1 qui est à proximité du boîtier de la montre. Alternativement, cette partie référencée 1 peut être un insert qui se fixe au bracelet. L'extrémité de ce bracelet 1 (ou l'insert 1) comprend des moyens d'attache ou de clipsage sous forme d'un tube ouvert 2 destiné à se clipser sur une barrette 3 de la montre. De préférence, l'ouverture du tube 4 est d'une taille inférieure au diamètre de la barrette 3 afin de réaliser un clipsage stable du bracelet sur la barrette 3. Dans ce mode d'exécution, on joue donc sur une déformation élastique du tube lorsque la barrette 3 est introduite dans le tube 2. Une fois la barrette 3 à l'intérieur du tube 2 (référence 3' dans la figure 1), ledit tube 2 reprend sa configuration "au repos" et la barrette 3' est maintenue dans le tube. Pour le "déclipsage", c'est-à-dire quand on veut enlever le bracelet de la montre, il suffit de forcer le passage de la barrette 3 vers l'extérieur du tube 2, qui va la laisser passer et reprendre sa forme "au repos".In a first embodiment, illustrated in figure 1 , there is shown a part of a bracelet 1 of a watch, namely the part of the bracelet 1 which is close to the watch case. Alternatively, this part referenced 1 may be an insert that attaches to the bracelet. The end of this bracelet 1 (or the insert 1) comprises fastening means or clipping in the form of an open tube 2 for clipping on a bar 3 of the watch. Preferably, the opening of the tube 4 is of a smaller size than the diameter of the bar 3 in order to achieve a stable clipping of the bracelet on the bar 3. In this embodiment, it plays therefore on an elastic deformation of the tube when the bar 3 is inserted into the tube 2. Once the bar 3 inside the tube 2 (reference 3 'in the figure 1 ), said tube 2 resumes its configuration "at rest" and the bar 3 'is held in the tube. For the "unclipping", that is to say when we want to remove the wristband from the watch, it is sufficient to force the passage of the bar 3 to the outside of the tube 2, which will let it pass and take its shape "at rest".

De préférence, dans ce mode d'exécution, la partie de bracelet 1 (ou le bracelet) est en matière synthétique et a été surmoulée sur le tube 2. Dans ce mode, la partie 1 peut donc être directement le bracelet (par exemple un bracelet en matière synthétique) ou alors une partie qui sera attachée sur un bracelet, que l'on nommera insert dans la suite.Preferably, in this embodiment, the bracelet part 1 (or bracelet) is made of synthetic material and has been overmolded onto the tube 2. In this mode, the part 1 can therefore be directly the bracelet (for example a plastic bracelet) or a part that will be attached to a bracelet, which will be named insert in the suite.

En effet, il est possible d'appliquer le principe de l'invention à un bracelet dans une autre matière, par exemple en cuir ou en métal, ou autre qui ne peut pas être surmoulé sur le tube 2. Dans ce cas, on utilise l'insert 1 qui lui est surmoulé, et cet insert sera ensuite fixé au bracelet par collage, couture etc. Cette façon de faire présente un intérêt particulier quand il n'est pas possible de fixer le tube de façon durable ou simple à la matière formant le bracelet. Ce principe peut s'appliquer à tous les modes d'exécution.Indeed, it is possible to apply the principle of the invention to a bracelet in another material, for example leather or metal, or other that can not be overmolded on the tube 2. In this case, it is used insert 1 which is overmolded, and this insert will then be attached to the bracelet by gluing, sewing etc. This is of particular interest when it is not possible to fix the tube permanently or simply to the material forming the bracelet. This principle can apply to all modes of execution.

Les figures 2 et 3 illustrent un autre mode d'exécution dans lequel les moyens d'attache sont formés par un élément creux 9 avec deux parties de diamètres différents, une première partie 9' ouverte et une deuxième partie 9" en forme de crochet. La barrette pénètre d'abord dans la première partie (barrette 3") et ensuite est forcée dans la deuxième partie 9" (barrette 3') qui est une position stable d'accroche. Comme il y a un bossage 10 entre les deux parties 9' et 9", la barrette va rester dans la position 3' et ne va pas ressortir. Le passage de la première partie 9' à la deuxième partie 9" se fait par exemple par déformation élastique de la partie 9' ou du bossage 10. Comme pour le mode d'exécution précédent, ce mode peut s'appliquer au bracelet directement (par exemple lorsque le bracelet est surmoulé sur la partie 9) ou à un insert 1 fixé ensuite au bracelet selon les principes de la présente invention et décrits ci-dessus.The Figures 2 and 3 illustrate another embodiment in which the fastening means are formed by a hollow element 9 with two parts of different diameters, a first part 9 'open and a second part 9 "in the form of a hook. firstly in the first part (bar 3 ") and then is forced into the second part 9" (bar 3 ') which is a stable hooking position As there is a boss 10 between the two parts 9' and 9 " , the bar will stay in the 3 'position and will not come out. The passage from the first portion 9 'to the second portion 9 "is done for example by elastic deformation of the portion 9' or the boss 10. As for the previous embodiment, this mode can be applied to the bracelet directly ( for example when the bracelet is overmoulded on the part 9) or an insert 1 then attached to the bracelet according to the principles of the present invention and described above.

La figure 3 illustre un mode d'exécution similaire à celui de la figure 2, mais sous une forme plus compacte dans lequel l'entrée de la première partie 9' est d'une dimension égale ou inférieure au diamètre de la barrette 3.The figure 3 illustrates a mode of execution similar to that of the figure 2 but in a more compact form in which the inlet of the first portion 9 'is of a size equal to or smaller than the diameter of the bar 3.

La figure 4 illustre un autre mode d'exécution . Dans ce mode le tube 2 est remplacé par un mousqueton 5. Ce système est plus sécurisé que le précédent, mais moins pratique et moins simple. De façon similaire aux modes d'exécution décrits précédemment, ce mode peut s'appliquer directement au bracelet (qui est surmoulé) ou à un insert 1 qui est aussi surmoulé, ledit insert étant ensuite attaché au bracelet. La fermeture 5' du mousqueton est illustrée en traits tiretés lors de l'introduction de la barrette 3 et en traits pleins après l'introduction de la barrette (référence 3'). Le mousqueton 5 peut être réalisée en toute matière appropriée, par exemple en plastique ou en métal.The figure 4 illustrates another mode of execution. In this mode the tube 2 is replaced by a carabiner 5. This system is more secure than the previous one, but less convenient and less simple. Similar to the embodiments described above, this mode can be applied directly to the bracelet (which is overmoulded) or to an insert 1 which is also overmolded, said insert then being attached to the bracelet. The closure 5 'of the carabiner is illustrated in dashed lines during the introduction of the bar 3 and in full lines after the introduction of the bar (reference 3'). The carabiner 5 can be made of any suitable material, for example plastic or metal.

La figure 5 illustre un autre mode d'exécution comprenant une cage recourbée 6 dans laquelle est introduite la barrette 3. Pour la maintenir dans la cage, un moyen ressort, ici un ressort à lame 7 est prévu. On peut également ajouter un bossage 8 dans la cage 6 pour éviter que la barrette 3 ne se déplace. Ce bossage 8 peut être réalisé par un bourrelet de matière, par exemple de la matière utilisée pour former la cage. Ce mode d'exécution peut par exemple servir à réaliser un insert 1 qui sera ensuite fixé au bracelet. Typiquement, ce serait le cas si l'on veut conserver un bracelet en cuir ou une autre matière qui n'est pas appropriée pour réaliser la cage. Cette cage peut donc former directement un insert qui est ensuite attaché au bracelet, par exemple par collage, couture ou autre ou elle peut être fixée à un insert qui sera attaché au bracelet. La cage 6 peut être réalisée en toute matière appropriée, par exemple en plastique ou en métal.The figure 5 illustrates another embodiment comprising a curved cage 6 into which is inserted the bar 3. To hold it in the cage, a spring means, here a leaf spring 7 is provided. We can also add a boss 8 in the cage 6 to prevent the bar 3 moves. This boss 8 may be made by a bead of material, for example the material used to form the cage. This embodiment can for example be used to make an insert 1 which will then be attached to the bracelet. Typically, this would be the case if one wants to keep a leather strap or other material that is not appropriate to achieve the cage. This cage can therefore directly form an insert which is then attached to the bracelet, for example by gluing, sewing or other or it can be attached to an insert that will be attached to the bracelet. The cage 6 can be made of any suitable material, for example plastic or metal.

La figure 6 illustre un autre mode d'exécution comprenant une cage 15 par exemple en métal ou en plastique, dans laquelle un élément ressort 16 est fixé. La barrette 3 est introduite dans la cage 15 et l'élément ressort 16 permet de la maintenir dans la cage 15, par exemple au moyen de bossages 17, 18. Ces bossages peuvent par exemple être formés directement sur le ressort 16 ou par un ajout de matière approprié. Dans ce mode d'exécution, la cage 15 peut être directement intégrée dans le bracelet (qui est par exemple surmoulé) ou alors faire partie d'un insert qui sera ensuite fixé au bracelet comme décrit ci-dessus.The figure 6 illustrates another embodiment comprising a cage 15 for example of metal or plastic, in which a spring element 16 is fixed. The bar 3 is inserted into the cage 15 and the spring element 16 makes it possible to hold it in the cage 15, for example by means of bosses 17, 18. These bosses can for example be formed directly on the spring 16 or by an addition of appropriate material. In this embodiment, the cage 15 can be directly integrated into the bracelet (which is for example overmolded) or be part of an insert which will then be attached to the bracelet as described above.

La figure 7 illustre un autre mode d'exécution. Dans ce mode, le système de fixation comprend un crochet 20 dans lequel se trouve un ressort 21 qui plaque la barrette 3 à l'intérieur du crochet 20. Ce crochet peut être une prolongation du bracelet 22 ou former un insert qui est fixé à un bracelet. La référence 23 indique le boîtier de la montre à laquelle le bracelet est attaché.The figure 7 illustrates another mode of execution. In this mode, the fixing system comprises a hook 20 in which there is a spring 21 which plates the bar 3 inside the hook 20. This hook may be an extension of the bracelet 22 or form an insert which is fixed to a bracelet. Reference 23 indicates the case of the watch to which the bracelet is attached.

La figure 8 illustre le principe de fixation du système selon l'invention à un boîtier de montre. Dans cette figure, le système de fixation sera référencé 24 comme identification générale et le bracelet/insert 25 mais il est clair que tous les modes d'exécution décrits dans la présente demande peuvent être concernés par le principe exposé dans cette figure 8 et peuvent fonctionner selon ce principe. D'autres principes sont bien entendu possibles en fonction de la configuration des éléments formant le dispositif et l'invention ne se limite pas à la fixation d'un bracelet sur un boîtier de montre.The figure 8 illustrates the principle of fixing the system according to the invention to a watch case. In this figure, the fastening system will be referenced 24 as general identification and the bracelet / insert 25 but it is clear that all the embodiments described in the present application may be concerned by the principle set forth in this document. figure 8 and can work according to this principle. Other principles are of course possible depending on the configuration of the elements forming the device and the invention is not limited to the attachment of a bracelet on a watch case.

Dans une première étape (1), on insère la barrette 3 (ou un axe) dans le système de fixation 24. Cette étape s'effectue de préférence en orientant le bracelet/insert 25 à environ 90° par rapport au boîtier comme illustré. Ensuite, en (2), la barrette 3 est amenée dans sa position stable dans le système de fixation.In a first step (1), the bar 3 (or an axis) is inserted into the fixing system 24. This step is preferably carried out by orienting the bracelet / insert 25 at approximately 90 ° with respect to the housing as illustrated. Then, in (2), the bar 3 is brought into its stable position in the fixing system.

Finalement, en (3), le bracelet/insert 25 est amené dans sa position d'utilisation qui sera celle prise lors du port de la montre. Dans cette position, le système est naturellement verrouillé car un mouvement de sortie de la barrette est empêché par le boitier de la montre 23. On évite donc le risque de perte de la montre par ce verrouillage.Finally, in (3), the bracelet / insert 25 is brought into its position of use which will be that taken during the wearing of the watch. In this position, the system is naturally locked because an exit movement of the bar is prevented by the case of the watch 23. This avoids the risk of loss of the watch by this lock.

La figure 9 illustre un mode d'exécution de l'invention. Dans ce mode, le système comprend des moyens de verrouillage qui sont décrits plus en détail ci-dessous. Plus précisément, le système comprend un insert 30 qui est fixé au bracelet d'une montre par exemple. Le bracelet et l'insert 30 peuvent être attachés par différents moyens et principes (notamment en fonction des matières utilisées): collage, couture, surmoulage du bracelet sur l'insert etc. Alternativement, l'insert peut être formé directement par le bracelet et ne pas être une pièce fixée au bracelet.The figure 9 illustrates an embodiment of the invention. In this mode, the system comprises locking means which are described in more detail below. More specifically, the system comprises an insert 30 which is attached to the wristband of a watch for example. The bracelet and the insert 30 can be attached by various means and principles (in particular depending on the materials used): gluing, sewing, overmoulding of the bracelet on the insert, etc. Alternatively, the insert can be formed directly by the bracelet and not be a piece attached to the bracelet.

Dans le mode d'exécution de la figure 9, on utilise des moyens de verrouillage qui permettent d'assurer le montage du système par exemple sur un boîtier de montre. Ces moyens de verrouillage comprennent notamment une lame flexible 31, par exemple en métal ou en tout autre matière adéquate, qui est actionnée par des moyens d'actionnement comprenant par exemple un bouton-poussoir 32. Lors du montage, il n'est pas forcément nécessaire d'actionner le bouton 32 et la barrette 3 est introduite dans l'insert en poussant la lame 31 (voir la position de la lame illustrée en traits tiretés dans le figure 9). Une fois la barrette entièrement introduite (référence 3'), la lame 31 peut revenir à sa position initiale (par exemple de repos) qui est celle illustrée en traits pleins dans la figure. Dans cet état, la barrette 3' est clipsée et ne peut plus ressortir de l'insert 30.In the execution mode of the figure 9 locking means are used which make it possible to assemble the system for example on a watch case. These locking means comprise in particular a flexible blade 31, for example of metal or any other suitable material, which is actuated by actuating means comprising for example a push-button 32. During assembly, it is not necessarily necessary necessary to actuate the button 32 and the bar 3 is inserted into the insert by pushing the blade 31 (see position of the blade illustrated in dashed lines in the figure 9 ). Once the bar is fully inserted (reference 3 '), the blade 31 can return to its initial position (for example rest) which is that shown in solid lines in the figure. In this state, the bar 3 'is clipped and can not come out of the insert 30.

Lorsque l'on veut enlever le bracelet de la montre (par exemple), il est nécessaire d'actionner le bouton 32, par exemple par pression, pour repousser la lame 31 au fond de l'insert 30, dans la position illustrée par des traits tiretés pour permettre la sortie de la barrette (de 3' à 3).When it is desired to remove the wristband from the watch (for example), it is necessary to actuate the button 32, for example by pressing, to push the blade 31 to the bottom of the insert 30, in the position illustrated by dashed lines to allow the output of the bar (3 'to 3).

Le bouton a par exemple une forme cylindrique avec une collerette 33 pour éviter qu'il ne tombe, ou d'autres moyens équivalents pour obtenir le même effet. Le bouton 32 peut bien entendu avoir toute forme appropriée et être formé en toute matière appropriée: synthétique, métal, alliages, mélanges etc.The button has for example a cylindrical shape with a flange 33 to prevent it from falling, or other equivalent means to obtain the same effect. The button 32 may of course have any suitable shape and be formed of any suitable material: synthetic, metal, alloys, mixtures etc.

La solution de l'utilisation d'un mécanisme avec une lame comme décrit dans la présente demande, permet de rendre la construction très fine en épaisseur, ce qui est important pour un bracelet, par exemple de montre.The solution of the use of a mechanism with a blade as described in the present application makes it possible to make the construction very thin in thickness, which is important for a bracelet, for example a watch.

Le bouton poussoir 32 peut également être fixé sur la lame (p.ex. comme une pièce rapportée), ou tout autre solution, y compris la lame 31 elle-même pourrait avoir une géométrie incluant cette fonction de bouton poussoir. Cette variante est illustrée en figure 10 et comprend les mêmes éléments que ceux décrits en référence à la figure 9. La lame 31 est toutefois différente et elle comprend un bossage 34 qui remplace le bouton poussoir 32 de la figure 9. Cette variante a l'avantage de la simplicité avec un nombre réduit de pièces nécessaires. Dans une variante, on pourrait combiner un bossage et un bouton.The push button 32 may also be attached to the blade (eg as an insert), or any other solution, including the blade 31 itself could have a geometry including this push button function. This variant is illustrated in figure 10 and includes the same elements as those described with reference to the figure 9 . The blade 31 is however different and it comprises a boss 34 which replaces the push button 32 of the figure 9 . This variant has the advantage of simplicity with a reduced number of necessary parts. In a variant, one could combine a boss and a button.

Comme décrit ci-dessus, la lame 31 peut notamment comprendre deux pliures, l'une pour limiter la course (pliure 1) et l'autre pour maintenir le bouton en position stable contre un arrêt (pliure 2). Ces pliures sont illustrées dans les figures 9 et 10 par les références P1 et P2.As described above, the blade 31 may in particular comprise two folds, one to limit the stroke (fold 1) and the other to hold the button in stable position against a stop (fold 2). These folds are illustrated in the Figures 9 and 10 by the references P1 and P2.

Comme indiqué ci-dessus, de préférence un bouton 32 actionne la lame 31 pour libérer la barrette 3. D'autres moyens équivalents au bouton, par exemple forme de la lame ou autres sont possibles et envisageables dans le cadre de l'invention.As indicated above, preferably a button 32 actuates the blade 31 to release the bar 3. Other means equivalent to the button, for example shape of the blade or others are possible and possible within the scope of the invention.

On peut prévoir une rampe 35 sur l'insert 1 afin de permettre une extraction guidée et facile de la barrette 3, voir les figures 9 et 10. Une telle rampe 35 peut être appliquée dans tous les modes ou non.A ramp 35 can be provided on the insert 1 in order to allow guided and easy extraction of the bar 3, see FIGS. Figures 9 and 10 . Such a ramp 35 can be applied in all modes or not.

Dans la construction selon l'invention, il suffit que la lame 31 passe au-dessus de l'axe de la barrette 3 pour que l'extraction soit possible de sorte que la course nécessaire de la lame 31 est très faible ce qui permet le montage du système sur des bracelets fins.In the construction according to the invention, it suffices that the blade 31 passes above the axis of the bar 3 so that the extraction is possible so that the necessary stroke of the blade 31 is very small which allows the mounting the system on fine bracelets.

La figure 11 illustre un autre mode d'exécution de l'invention. Dans ce mode, le bouton 32 est articulé sur l'insert 1 par un axe 36 et comprend une extension 37 pour faciliter son actionnement par un utilisateur.The figure 11 illustrates another embodiment of the invention. In this mode, the button 32 is articulated on the insert 1 by an axis 36 and includes an extension 37 to facilitate its actuation by a user.

La figure 12 illustre un autre mode d'exécution de l'invention qui fait appel à un élément élastique 40, par exemple un ressort ou une lame ressort, fixé à l'intérieur de l'insert pour rattraper le jeu autour de la barrette 3. Cet élément 40 peut s'utiliser dans tous les modes d'exécution de l'invention et le jeu peut être rattrapé par exemple par les trois points d'appui sur la barrette, formés par l'élément ressort 40, la rampe 35 et la lame 31. Le sens de rattrapage du jeu est illustré dans la figure 11 par la flèche à deux sens. L'élément 40 peut avoir toute forme appropriée: arrondie ou autre.The figure 12 illustrates another embodiment of the invention which uses an elastic element 40, for example a spring or a leaf spring, fixed inside the insert to catch the game around the bar 3. This element 40 can be used in all embodiments of the invention and the game can be overtaken for example by the three points of support on the bar, formed by the spring element 40, the ramp 35 and the blade 31 The catch-up sense of the game is illustrated in the figure 11 by the two-way arrow. The element 40 may have any suitable shape: rounded or otherwise.

Dans le système illustré dans la figure 12, la position de la lame au repos est que l'extrémité de la lame doit être de préférence en dessous de l'axe passant au centre de la barrette ou axe 3. La pliure de la lame permet notamment de régler la sécurité de verrouillage du bracelet qui est donnée par la distance selon l'axe Y entre l'extrémité de la lame et l'axe horizontal passant par le centre de la barrette ou axe.In the system illustrated in the figure 12 , the position of the blade at rest is that the end of the blade should preferably be below the passing axis in the center of the bar or axis 3. The folding of the blade allows in particular to adjust the locking security of the bracelet which is given by the distance along the Y axis between the end of the blade and the horizontal axis passing through the center of the bar or axis.

La figure 13 montre différents modes d'exécution de la lame 31 selon l'invention, illustrés dans les détails 1 à 3.The figure 13 shows different embodiments of the blade 31 according to the invention, illustrated in details 1 to 3.

Dans le détail 1: la lame 31 comprend des découpes 41 à son extrémité et les parties 42, 43, 44 sont pliées l'une par rapport à l'autre. Par exemple, les parties 42 et 44 sont dans le même plan tandis que la partie centrale 43 est pliée vers le haut. Bien entendu, le nombre de découpe n'est qu'un exemple et on peut imaginer une variante avec une seule découpe, ou plus de deux découpes.In detail 1: the blade 31 comprises cutouts 41 at its end and the parts 42, 43, 44 are folded relative to each other. For example, the parts 42 and 44 are in the same plane while the central portion 43 is folded upwards. Of course, the number of cuts is only an example and one can imagine a variant with a single cut, or more than two cuts.

Dans le détail 2: l'extrémité de la lame 31 comprend une déformation 45 en forme de pont. Cette déformation 45 peut être centrée (comme dans le détail 2) ou non. De même, on peut prévoir une seule déformation 45 ou plusieurs, de forme et/ou de position symétrique ou non.In detail 2: the end of the blade 31 comprises a deformation 45 in the form of a bridge. This deformation 45 may be centered (as in detail 2) or not. Similarly, one can provide a single deformation 45 or more, of shape and / or symmetrical position or not.

Dans le détail 3: ici on a illustré un mode d'exécution avec une pièce rapportée 46 avec deux parties en forme de pont 47, 48. Dans le cadre de l'invention, on peut prévoir que la partie rapportée 46 ait une autre forme, un seul pont (comme dans le détail 2) ou plusieurs. La construction peut être symétrique ou non. La pièce rapportée peut être en toute matière appropriée, la même que la lame 31 ou non. Elle peut être fixée par tout procédé approprié (collage, soudure, vissage, formes complémentaires, insertion etc...).In detail 3: here is illustrated an embodiment with an insert 46 with two bridge-shaped parts 47, 48. Within the scope of the invention, it can be provided that the insert 46 has another shape , only one bridge (as in detail 2) or more. The construction may be symmetrical or not. The insert may be of any suitable material, the same as the blade 31 or not. It can be fixed by any appropriate process (gluing, welding, screwing, complementary shapes, insertion etc ...).

Ces variantes de lames 31 et leurs équivalents sont utilisables dans tous les modes d'exécution de l'invention.These blade variants 31 and their equivalents can be used in all the embodiments of the invention.

La figure 14 illustre un autre mode d'exécution de l'invention. Dans celui-ci, l'insert 30 et la lame ressort 31 possèdent une encoche ou découpe 50, respectivement 51, permettant à l'ensemble de se monter sur une boucle ardillon. L'encoche 50 a pour objectif de permettre le passage de l'ardillon d'une boucle de bracelet et ainsi de permettre l'utilisation de ce système selon l'invention sur l'interchangeabilité d'une boucle de bracelet montre ou de ceinture. Comme on le comprend aisément, l'invention a de nombreuses applications et n'est pas limitée aux exemples décrits dans la présente demande.The figure 14 illustrates another embodiment of the invention. In this, the insert 30 and the leaf spring 31 have a notch or cutout 50, respectively 51, allowing the assembly to be mounted on a pin buckle. The notch 50 is intended to allow the passage of the barb of a bracelet loop and thus allow the use of this system according to the invention on the interchangeability of a wristband or belt buckle. As is readily understood, the invention has many applications and is not limited to the examples described in this application.

Ces constructions particulières de la lame permettent d'une part par le point bas d'empêcher la sortie de la barrette 3 et d'autre part, par le point haut, de limiter le jeu autour de la barrette 3.These particular constructions of the blade allow on the one hand by the low point to prevent the exit of the bar 3 and on the other hand, by the high point, to limit the game around the bar 3.

La lame 31 est attaché à l'insert 30 ou au bracelet par tout moyen approprié: collage, vissage, couture, surmoulage (de l'insert) etc.The blade 31 is attached to the insert 30 or to the bracelet by any appropriate means: gluing, screwing, sewing, over-molding (of the insert), etc.

La présente invention n'est pas limitée aux modes d'exécution illustrés qui sont donnés à titre d'exemples illustratifs et non-limitatifs. Des variantes sont possibles dans le cadre de la protection revendiquée dans des modes d'exécution différents, ou en faisant appel à des moyens équivalents par exemple.The present invention is not limited to the illustrated embodiments which are given by way of illustrative and non-limiting examples. Variations are possible in the context of the protection claimed in different embodiments, or by using equivalent means for example.

Par exemple, dans les modes d'exécution décrits, on peut ajouter des moyens de verrouillage et déverrouillage du système ou des moyens d'attache afin d'assurer le montage des éléments. De plus on peut également prévoir d'autres moyens facilitant la manipulation, par exemple du type bouton-poussoir. De tels moyens peuvent être combinés pour apporter à la fois la fonction de verrouillage/déverrouillage et faciliter la manipulation, comme par exemple illustré dans les modes d'exécution de l'invention.For example, in the embodiments described, can be added locking means and unlocking the system or fastening means to ensure the mounting of the elements. In addition, it is also possible to provide other means facilitating handling, for example of the push button type. Such means can be combined to provide both the locking / unlocking function and facilitate handling, as for example illustrated in the embodiments of the invention.

Les caractéristiques techniques illustrées sur certains modes d'exécution peuvent s'appliquer à d'autres modes d'exécution, notamment si ces moyens ne sont pas spécifiquement discutés en relation avec ces autres modes. Par exemple, le bouton 32 (des figures 9 et 11) peut être utilisé sur tous les modes d'exécution, par exemple ceux des figures 12 à 14. Les détails 1 à 3 de la figure 13 peuvent s'appliquer lames des autres modes d'exécution. De nombreuses variantes peuvent donc être envisagées en combinant les caractéristiques d'un mode d'exécution avec un autre.The technical features illustrated in some embodiments can be applied to other modes of execution, especially if these means are not specifically discussed in relation to these other modes. For example, the 32 button ( figures 9 and 11 ) can be used on all modes of execution, for example those of Figures 12 to 14 . Details 1 to 3 of the figure 13 may apply blades of other modes of execution. Many variants can therefore be envisaged by combining the characteristics of one embodiment with another.

La présente invention et les moyens d'attache de celle-ci ont de nombreux avantages sur les systèmes connus.

  • -) le système est simple et facile d'emploi. Les bracelets peuvent donc facilement être échangés, par exemple pour les adapter à une tenue ou une activité;
  • -) en cas d'usure du bracelet, il peut aussi facilement être remplacé;
  • -) la position du bracelet lorsque que la montre est portée est une position de sécurité dans laquelle le bracelet ne peut pas être détaché (ou "déclipsé") ce qui évite les risques de perte de la montre.
The present invention and the attachment means thereof have many advantages over known systems.
  • -) the system is simple and easy to use. Bracelets can therefore easily be exchanged, for example to adapt to an outfit or activity;
  • -) in case of wear of the bracelet, it can also easily be replaced;
  • -) the position of the bracelet when the watch is worn is a safety position in which the bracelet can not be detached (or "unclipped") which avoids the risk of loss of the watch.

Comme indiqué ci-dessus, le système peut être formé sur le bracelet, ou attaché à celui-ci ou encore faire partie d'un insert qui est lui-même attaché à un bracelet. Le système peut être utilisé également pour attacher une boucle ardillon ou une boucle déployante à un bracelet.As indicated above, the system can be formed on the bracelet, or attached to it or be part of an insert which is itself attached to a bracelet. The system can also be used to attach a pin buckle or folding clasp to a bracelet.

Bien entendu, la présente invention s'applique de préférence aux deux extrémités du bracelet d'une montre, soit pour son attache au boîtier, soit pour la boucle de bracelet avec ardillon, ou alors par exemple à une ceinture . Son principe peut aussi être utilisé sur d'autres objets similaires, comme une ceinture ou une lanière et ne se limite pas aux applications mentionnées dans la présente demande.Of course, the present invention is preferably applied to both ends of the wristband of a watch, either for its attachment to the case, or for the bracelet buckle with barb, or so for example to a belt. Its principle can also be used on other similar objects, such as a belt or lanyard and is not limited to the applications mentioned in this application.

Toutes matières appropriées peuvent être utilisées pour les différentes parties de l'invention, par exemple le métal ou des alliages, des matières synthétiques et autres, également en combinaison. Des moyens de renforcement peuvent aussi être prévus.Any suitable materials may be used for the various parts of the invention, for example metal or alloys, plastics and the like, also in combination. Reinforcing means may also be provided.
