Description

DISPOSITIF POUR LA FIXATION D'UN BRACELET A UNE BOITE DE MONTRE DEVICE FOR FIXING A BRACELET TO A WATCH CASE
La présente invention concerne un dispositif pour la fixation d'un bracelet à une boîte de montre comportant une carrure munie d'une paire de cornes de fixation du bracelet, et plus particulièrement un tel dispositif permettant d' interchanger le bracelet de façon simple, sans outil et sans risquer d'endommager la boîte et/ou le bracelet .The present invention relates to a device for attaching a bracelet to a watch case comprising a middle part provided with a pair of strap fixing lugs, and more particularly such a device making it possible to interchange the bracelet in a simple manner, without tool and without risking damage to the case and / or the bracelet.
Un bracelet de montre est généralement fixé sur les cornes de la boîte de montre au moyen de barrettes sur lesquelles sont adaptés les brins du bracelet, les extrémités des barrettes étant fixées aux cornes de la boîte de montre. Les barrettes le plus souvent utilisées sont dites barrettes à ressort et comprennent à leurs extrémités deux pivots. Ces pivots sont mobiles à l'intérieur d'un tube central et sont soumis à l'action d'un ressort, lui aussi logé à l'intérieur du tube, et poussant les pivots vers l'extérieur. Les cornes sont munies de trous correspondants dans lesquels les pivots des barrettes pénètrent . Les deux cornes sont parallèles et généralement écartées l'une de l'autre de quinze à vingt millimètres .A watch strap is generally fixed on the horns of the watch case by means of bars on which the strands of the bracelet are adapted, the ends of the bars being fixed to the horns of the watch case. The bars most often used are called spring bars and comprise at their ends two pivots. These pivots are movable inside a central tube and are subjected to the action of a spring, also housed inside the tube, and pushing the pivots outwards. The horns are provided with corresponding holes in which the pivots of the bars penetrate. The two horns are parallel and generally spaced from one another by fifteen to twenty millimeters.
Un tel système de fixation du bracelet sur la boîte de montre présente l'inconvénient de nécessiter dans la plupart des cas l'intervention d'un professionnel pour démonter le bracelet lorsque ce dernier doit être remplacé par un autre. En outre, cette opération de démontage est réalisée avec un outil spécialisé, par exemple des brucelles, qui risque de blesser la boîte de montre. Ce système n'est par conséquent pas très satisfaisant et ne répond pas aux exigences actuelles du marché qui demande des dispositifs de fixation de bracelet permettant aux utilisateurs eux-mêmes de remplacer facilement leur bracelet par un autre. On peut par exemple souhaiter à tout moment de la journée adapter le type de sa montre- bracelet au gré des circonstances, et donc pouvoir facilement changer soi-même de bracelet, par exemple pour avoir un bracelet assorti à la couleur des ses vêtements . L'invention a donc pour but principal de remédier aux inconvénients de l'art antérieur susmentionné en fournissant un dispositif de fixation rapide d'un bracelet de montre, sûr et peu coûteux, qui puisse être mis en oeuvre aisément par l'utilisateur lui-même, qui s'adapte à n'importe quel type de bracelet et qui ne nuise pas à l'esthétique de la montre.Such a system for fixing the strap to the watch case has the drawback of requiring in most cases the intervention of a professional to dismantle the strap when the latter has to be replaced by another. In addition, this disassembly operation is carried out with a specialized tool, for example tweezers, which may injure the watch case. This system is therefore not very satisfactory and does not meet the current requirements of the market which requires bracelet fixing devices allowing the users themselves to easily replace their bracelet with another. For example, we may wish to At any time of the day, adapt the type of your wristwatch according to the circumstances, and therefore be able to easily change your own bracelet, for example to have a bracelet matching the color of your clothes. The main object of the invention is therefore to remedy the drawbacks of the aforementioned prior art by providing a device for rapidly fixing a watch strap, which is safe and inexpensive, which can be easily implemented by the user himself. even, which adapts to any type of bracelet and which does not affect the aesthetics of the watch.
A cet effet, l'invention a pour objet un dispositif pour la fixation d'un bracelet à une boîte de montre comportant une carrure munie d'une paire de cornes de fixation de bracelet, ce dispositif permettant l'accouplement et le désaccouplement instantané d'un brin du bracelet à la carrure sans outil ni connaissance particulière ou contrôle visuel, caractérisé en ce qu'une des extrémités du bracelet est solidaire d'une plaque comportant deux paires d'ergots, et coopérant avec deux paires de rainures prévues dans des faces latérales des cornes .To this end, the subject of the invention is a device for fixing a bracelet to a watch case comprising a middle part provided with a pair of strap fixing horns, this device allowing instant coupling and uncoupling of '' a strand of the bracelet with the middle part without any tool or special knowledge or visual inspection, characterized in that one of the ends of the bracelet is integral with a plate comprising two pairs of lugs, and cooperating with two pairs of grooves provided in lateral faces of the horns.
Grâce à ces caractéristiques, l'utilisateur peut aisément démonter ou remonter le bracelet sur une boîte de montre en introduisant les ergots dans les rainures auxquelles ils sont associés et en les calant dans le fond de celles-ci.Thanks to these characteristics, the user can easily disassemble or reassemble the bracelet on a watch case by inserting the lugs into the grooves with which they are associated and by wedging them in the bottom thereof.
Un autre avantage du présent dispositif de fixation réside dans le fait que les points de liaison du bracelet à la boîte de montre sont multipliés par deux et permettent une liaison solide et fiable.Another advantage of the present fixing device lies in the fact that the connection points of the bracelet to the watch case are multiplied by two and allow a solid and reliable connection.
Un autre avantage encore du présent dispositif de fixation réside dans le fait qu'il peut être indifféremment utilisé avec des bracelets souples, par exemple en cuir ou tissu, et avec des bracelets à maillons métalliques .Yet another advantage of the present fastening device lies in the fact that it can be indifferently used with flexible bracelets, for example leather or fabric, and with bracelets with metal links.
Selon une caractéristique de l'invention, chaque paire de rainures comprend une rainure rectiligne et une rainure coudée présentant une partie d'introduction rectiligne prolongée par une partie en retour.According to a characteristic of the invention, each pair of grooves comprises a rectilinear groove and a bent groove having a rectilinear introduction part extended by a return part.
Selon un mode de réalisation préféré de l'invention, les ergots sont disposés respectivement le long des bords longitudinaux de ladite plaque et en ce que les rainures sont ménagées sur les parois latérales en regard des cornes .According to a preferred embodiment of the invention, the lugs are disposed respectively along the longitudinal edges of said plate and in that the grooves are formed on the side walls opposite the horns.
D'autres avantages et caractéristiques de l'invention apparaîtront plus clairement à la lecture de la description suivante d'un mode de réalisation de l'invention donné à titre purement illustratif et non limitatif, cette description étant faite en liaison avec les dessins dans lesquels : la figure 1 est une vue en perspective du dispositif de fixation selon l'invention; les figures 2 et 3 sont des vues en coupe partielle représentant les formes et usinages des rainures ménagés dans le dispositif de l'invention, et les figures 4, 5 et 6 représentent respectivement dans l'ordre, les positions relatives des ergots dans les rainures au cours du montage du bracelet sur la boîte de montre à l'aide du dispositif de fixation selon l' invention.Other advantages and characteristics of the invention will appear more clearly on reading the following description of an embodiment of the invention given purely by way of non-limiting illustration, this description being made in conjunction with the drawings in which : Figure 1 is a perspective view of the fixing device according to the invention; Figures 2 and 3 are partial sectional views showing the shapes and machining of the grooves formed in the device of the invention, and Figures 4, 5 and 6 show respectively in order, the relative positions of the pins in the grooves during the mounting of the strap on the watch case using the fixing device according to the invention.
La figure 1 est une vue partielle en perspective d'une boîte de montre comprenant une carrure 2 et d'une extrémité d'un bracelet 1 destiné à être attaché de façon articulée sur la carrure 2 à l'aide du dispositif selon l'invention. La carrure 2 comprend deux paires de cornes de fixation 2f du bracelet 1, une seule paire de ces cornes 2f étant représentée sur la figure. Les deux paires de cornes 2f sont placées de façon classique sur les côtés opposés de la carrure 2, à 12 heures et à 6 heures. Par cornes, on comprendra dans le contexte de l'invention tout élément de forme variée servant à attacher le bracelet 1 à la boîte de montre. Ces cornes 2e peuvent épouser la forme générale de la carrure 2, mais pas nécessairement. On notera que les éléments d'attache se rattachant peu ou pas à la carrure 2, ou encore rapportés sur la boîte, sont également compris dans cette définition générale des cornes .Figure 1 is a partial perspective view of a watch case comprising a middle part 2 and one end of a strap 1 intended to be attached in an articulated manner to the middle part 2 using the device according to the invention . The middle part 2 comprises two pairs of fixing horns 2f of the bracelet 1, a single pair of these horns 2f being shown in the figure. The two pairs of horns 2f are placed in a conventional manner on the opposite sides of the middle part 2, at 12 o'clock and at 6 o'clock. By horns, it will be understood in the context of the invention any element of varied shape used to attach the strap 1 to the watch case. These 2nd horns can follow the general shape of the middle part 2, but not necessarily. It will be noted that the fastening elements which are attached little or not to the middle part 2, or even attached to the case, are also included in this general definition of horns.
Avec cette nouvelle invention, les trous à l'intérieur des cornes 2f sont remplacés par deux paires de rainures 2a, 2b et 2c, 2d. Les rainures 2b et 2c sont droites/rectilignes et verticales, alors que les rainures 2a et 2d sont coudées, permettant ainsi le guidage jusqu'au calage du bracelet 1. Les rainures 2a, 2d coudées présentent une partie d'introduction rectiligne prolongée par une partie en retour. Les rainures 2b, 2c rectilignes sont proximales, et les rainures 2a, 2d coudées sont distales relativement à la carrure 2. Comme cela ressort en particulier de la figure 3, on voit que les retours s ' étendent vers 1 ' extérieur de la carrure 2 et que la partie d'introduction rectiligne et la partie en retour forment de préférence un angle aiguë entre elles, typiquement de l'ordre de 45°.With this new invention, the holes inside the horns 2f are replaced by two pairs of grooves 2a, 2b and 2c, 2d. The grooves 2b and 2c are straight / rectilinear and vertical, while the grooves 2a and 2d are bent, thus allowing guiding until the setting of the strap 1. The grooves 2a, 2d bent have a rectilinear introduction part extended by a part in return. The rectilinear grooves 2b, 2c are proximal, and the angled grooves 2a, 2d are distal relative to the middle part 2. As can be seen in particular from FIG. 3, it can be seen that the returns extend towards the outside of the middle part 2 and that the rectilinear introduction part and the return part preferably form an acute angle between them, typically of the order of 45 °.
Sur le bracelet 1, l'invention se traduit par une plaque 4, de préférence rigide et légèrement cintrée, épousant la forme du poignet et munie de quatre ergots 4a, 4b, 4c et 4d qui viendront prendre place dans les rainures 2a, 2b, 2c, 2d ménagées à l'intérieur des cornes 2e, plus précisément sur les parois latérales en regard de ces cornes 2e. De préférence, les ergots 4a, 4b, 4c, 4d sont ménagés a l'extrémité libre de la plaque 4 et sont disposés respectivement le long des bords longitudinaux extérieurs de cette plaque.On bracelet 1, the invention results in a plate 4, preferably rigid and slightly curved, matching the shape of the wrist and provided with four lugs 4a, 4b, 4c and 4d which will take their place in the grooves 2a, 2b, 2c, 2d formed inside the horns 2e, more precisely on the side walls opposite these horns 2e. Preferably, the pins 4a, 4b, 4c, 4d are formed at the free end of the plate 4 and are arranged respectively along the outer longitudinal edges of this plate.
Ces ergots 4a, 4b, 4c, 4d peuvent être réalisés de façon industrielle sous la forme d'axes traversants, de tétons rapportés par soudure, par sertissage ou par tout autre moyen, ou peuvent faire partie intégrante de la plaque 4. La plaque 4 peut être perforée, rainurée ou bosselée pour faciliter l'adaptation de tout type de bracelet (cuir, métal, plastique, tissu, caoutchouc etc.). La plaque 4 étant identique pour chaque côté de la carrure 2, il est donc possible d'inverser chaque demi-bracelet pour satisfaire les besoins des droitiers et des gauchers. Les plaques 4 devant être de préférence rigides, l'emploi de tout matériau le permettant est envisageable.These lugs 4a, 4b, 4c, 4d can be produced industrially in the form of through axes, pins mounted by welding, crimping or by any other means, or can be an integral part of the plate 4. The plate 4 can be perforated, grooved or embossed to facilitate the adaptation of any type of bracelet (leather, metal, plastic, fabric, rubber etc.). Since the plate 4 is identical for each side of the middle part 2, it is therefore possible to reverse each half-bracelet to satisfy the needs of right-handers and left-handers. The plates 4 should preferably be rigid, the use of any material allowing it is possible.
En référence à ces dessins, pour le fonctionnement de cette nouvelle invention, il suffit de présenter la plaque 4 entre les cornes 2f de la carrure 2, de faire coulisser les ergots ld et la dans les rainures 2a et 2d, puis de tirer la plaque 4 vers le haut et à droite comme 1 ' indique la figure 4, en basculant la plaque 4 vers le bas, les ergots la et ld venant alors automatiquement au fond des rainures 2a et 2d tout en faisant monter les ergots lb et le dans les rainures 2b et 2c comme 1 ' indique la figure 5.With reference to these drawings, for the operation of this new invention, it suffices to present the plate 4 between the horns 2f of the middle part 2, to slide the lugs ld and la in the grooves 2a and 2d, then to pull the plate 4 upwards and to the right as 1 'indicates FIG. 4, by tilting the plate 4 downwards, the lugs la and ld then automatically coming to the bottom of the grooves 2a and 2d while raising the lugs lb and the in the grooves 2b and 2c as 1 'indicates Figure 5.
En poursuivant le même mouvement, les ergots lb, le montent automatiquement en butée dans les rainures 2b, 2c, rendant ainsi la plaque 4, et donc le bracelet 1 instantanément solidaire de la carrure 2, et donc de la montre, sans aucune fixation, comme l'indique la figure 6.Continuing the same movement, the lugs lb, automatically mount it in abutment in the grooves 2b, 2c, thus making the plate 4, and therefore the bracelet 1 instantly integral with the middle part 2, and therefore with the watch, without any fixing, as shown in Figure 6.
Le maintien final se fait par la mise au poignet de la montre .The final support is done by putting on the wrist of the watch.
Pour enlever la plaque 4 de la montre, autrement dit de la carrure 2, il suffira de faire la manoeuvre inverse.To remove the plate 4 from the watch, in other words from the middle part 2, it will suffice to do the reverse maneuver.
Selon une variante d'exécution de l'invention non représentée, un taquet de blocage matérialisé par une bille, par exemple rappelée par un ressort, un bossage ou tout autre moyen mécanique sur la carrure 2 ou la plaque 4 peut être rajouté.According to an alternative embodiment of the invention not shown, a blocking stop materialized by a ball, for example recalled by a spring, a boss or any other mechanical means on the middle part 2 or the plate 4 can be added.
Les formes de la carrure 1, des cornes 2f et de la plaque 4 ainsi que les proportions ne sont bien évidement pas limitatives .The shapes of the middle part 1, the horns 2f and the plate 4 as well as the proportions are obviously not limiting.
L'invention est particulièrement destinée : - à la fixation rapide, sûre, facile et sans outillage d'un bracelet à une montre; à la stabilisation du bracelet-montre sur le poignet sans serrage excessif de ce dernier; à une sécurité et une robustesse deux fois supérieure à la normale (quatre points au lieu de deux généralement) . The invention is particularly intended: - for fast, safe, easy and tool-free attachment of a bracelet to a watch; stabilizing the watch strap on the wrist without excessive tightening of the latter; twice as normal security and robustness (four points instead of two generally).
