The link (3) comprises a planar surface while its opposite surface is concave.

Description

FERMOIR DU TYPE A BOUCLE DEPLOYANTE DEPLOYMENT LOOP TYPE CLASP
La présente invention concerne un fermoir du type à boucle déployante pour bracelet, notamment pour bracelet de montre, comprenant deux branches cintrées articulées par une de leurs extrémités à un maillon intermédiaire, de sorte que lorsque l'une des branches est rabattue sur l'autre elle puisse occuper deux positions longitudinales différentes, l'une dans laquelle le maillon se trouve dans le prolongement de l'une des branches et une autre position selon laquelle le maillon se trouve dans le prolongement de l'autre branche, des moyens de verrouillage permettant d'assurer les deux positions longitudinales relatives des deux branches, l'autre extrémité de chaque branche étant munie de moyens pour recevoir l'extrémité d'un élément du bracelet .The present invention relates to a clasp of the folding clasp type for a bracelet, in particular for a watch strap, comprising two curved branches articulated by one of their ends to an intermediate link, so that when one of the branches is folded over the other it can occupy two different longitudinal positions, one in which the link is in the extension of one of the branches and another position in which the link is in the extension of the other branch, locking means allowing to ensure the two relative longitudinal positions of the two branches, the other end of each branch being provided with means for receiving the end of an element of the bracelet.
Il est connu du CH-A-663 552 un fermoir de ce type. Le but d'un tel fermoir est de pouvoir changer la longueur du bracelet facilement et sans utilisation d'un outillage spécial ou d'une modification de la longueur de l'une ou de l'autre de la branche, comme par exemple décrit dans le CH-A-571 327. Le maillon intermédiaire permet, par exemple, d'augmenter la longueur du bracelet lorsque l'utilisateur est momentanément gêné par son bracelet parce que son tour de poignet a augmenté, suite à un effort, la chaleur, etc.It is known from CH-A-663 552 a clasp of this type. The purpose of such a clasp is to be able to change the length of the bracelet easily and without the use of special tools or a modification of the length of one or the other of the branch, as for example described in CH-A-571 327. The intermediate link allows, for example, to increase the length of the bracelet when the user is temporarily hampered by his bracelet because his wrist circumference has increased, following an effort, the heat, etc.
Le dispositif décrit dans le CH 663 522 présente des inconvénients comme on peut aisément s'en rendre compte en se référant aux figures de ce document. En effet, dans les deux positions prévues du maillon et plus particulièrement lorsque le maillon se trouve dans le prolongement de la branche en contact avec le bracelet, l'extrémité de la boucle déployante se projette vers l'intérieur en créant une surépaisseur ce qui occasionne une gêne pour l'utilisateur. Accessoirement, le fait que les moyens de fixation soient constitués d'une ouverture oblongue dans une des branches coopérant avec un élément mâle, ne permet pas un verrouillage précis, et notamment on peut obtenir un glissement intempestif de l'élément mâle dans l'ouverture oblongue, compromettant ainsi la stabilité du verrouillage et modifiant la longueur du bracelet.The device described in CH 663 522 has drawbacks, as can easily be seen by referring to the figures in this document. Indeed, in the two planned positions of the link and more particularly when the link is in the extension of the branch in contact with the bracelet, the end of the folding clasp projects inward creating an extra thickness which causes discomfort for the user. Incidentally, the fact that the fixing means consist of an oblong opening in one of the branches cooperating with a male element, does not allow precise locking, and in particular it is possible to obtain an inadvertent sliding of the male element in the opening oblong, thereby compromising the stability of the locking mechanism and modifying the length of the bracelet.
La présente invention a pour but de proposer un palliatif aux inconvénients précités.The object of the present invention is to propose a remedy to the aforementioned drawbacks.
Ainsi, le fermoir selon l'invention est caractérisé par le fait que ledit maillon comprend une surface plane, laquelle est en fonction de la position longitudinale relative des deux branches soit en contact avec la face intérieure du bracelet, soit avec la peau de l'utilisateur et une surface opposée concave permettant au maillon, dans les deux positions susmentionnées de venir en contact étroit avec la surface de la branche avec laquelle le maillon ne se trouve pas dans son prolongement, tandis que la surface plane est au moins approximativement dans le prolongement de la tangente à l'extrémité de l'autre branche.Thus, the clasp according to the invention is characterized in that said link comprises a flat surface, which is a function of the relative longitudinal position of the two branches either in contact with the inner face of the bracelet, or with the skin of the user and a concave opposite surface allowing the link, in the two above-mentioned positions to come into close contact with the surface of the branch with which the link is not in its extension, while the flat surface is at least approximately in the extension from the tangent to the end of the other branch.
Le fait que le maillon présente une surface plane qui est, soit en contact avec la peau de l'utilisateur, soit avec le bracelet et le fait que la surface opposée est concave, permet dans les deux positions de la boucle d'obtenir une surface continue qui a pratiquement le même rayon dans les deux positions sans créer une extrémité qui se projette vers l'intérieur et provoque une gêne à l'utilisateur. Selon une variante préférée, le maillon est constitué de trois parties solidaires, chacune de ces parties a la forme approximative d'un coin, deux de ces parties étant disposées parallèlement l'une à l'autre, leurs extrémités présentant la plus grande hauteur formant l'une des extrémités du maillon articulée à une des branches, la troisième partie en forme de coin étant disposée entre elles et dans le sens contraire son extrémité de plus grande hauteur formant l'extrémité du maillon articulée à l'autre branche, que ladite extrémité de cette dernière branche ayant la forme d'un fer à cheval .The fact that the link has a flat surface which is either in contact with the wearer's skin or with the bracelet and the fact that the opposite surface is concave, allows in both positions of the loop to obtain a surface continuous which has practically the same radius in both positions without creating an end which projects inwards and causes discomfort to the user. According to a preferred variant, the link consists of three integral parts, each of these parts has the approximate shape of a corner, two of these parts being arranged parallel to each other, their ends having the greatest height forming one of the ends of the link articulated to one of the branches, the third wedge-shaped part being disposed between them and in the opposite direction its end of greater height forming the end of the link articulated to the other branch, than said end of this last branch having the shape of a horseshoe.
Comme il sera décrit par la suite, la forme du maillon permet d'obtenir une surface continue dans les deux positions de la boucle sans des parties qui se projette en dehors de la courbe formée par les deux branches de la boucle, la surface plane du maillon étant toujours au moins approximativement dans la direction de la tangente à l'extrémité de la courbe formée par l'une ou 1 ' autre branche .As will be described below, the shape of the link makes it possible to obtain a continuous surface in the two positions of the loop without parts which projects outside the curve formed by the two branches of the loop, the planar surface of the link being always at least approximately in the direction of the tangent at the end of the curve formed by one or the other branch.
Selon une variante d'exécution préférée, les moyens de verrouillage sont constitués par deux éléments femelles ou mâles situés sur l'une des branches et d'un élément mâle, respectivement femelle conjugué situé sur l'autre branche, les deux éléments femelles ou mâles correspondant exactement aux deux positions longitudinales relatives de deux branches lors du verrouillage .According to a preferred embodiment, the locking means are constituted by two female or male elements located on one of the branches and a male, respectively female conjugate element located on the other branch, the two female or male elements corresponding exactly to the two relative longitudinal positions of two branches during locking.
De cette manière en prévoyant sur l'une des branches, par exemple, des trous et l'autre un téton de forme correspondante, les deux trous étant situés de sorte à pouvoir verrouiller les deux branches dans l'une ou l'autre des positions de manière précise on évite un glissement intempestif.In this way by providing on one of the branches, for example, holes and the other a stud of corresponding shape, the two holes being located so that being able to lock the two arms in one or other of the positions in a precise manner, avoiding inadvertent sliding.
L'invention sera décrite plus en détail à l'aide du dessin annexé .The invention will be described in more detail using the attached drawing.
La figure 1 est une vue en perspective du fermoir à boucle déployante partiellement ouvert.Figure 1 is a perspective view of the partially open folding clasp.
La figure 2 est une vue de côté du maillon intermédiaire entre les deux branches de la boucle.Figure 2 is a side view of the intermediate link between the two branches of the loop.
La figure 3 est une vue en plan de la figure précédente .Figure 3 is a plan view of the previous figure.
La figure 4 est une vue de côté de la boucle dans une position de verrouillage.Figure 4 is a side view of the buckle in a locked position.
La figure 5 est une vue en plan de la figure précédente .Figure 5 is a plan view of the previous figure.
La figure 6 est une vue de côté de la boucle déployante dans la seconde position de verrouillage.Figure 6 is a side view of the folding clasp in the second locking position.
La figure 7 est une vue en plan de la figure précédente .Figure 7 is a plan view of the previous figure.
Le fermoir à boucle déployante de la figure 1 est composé de deux branches cintrées 1, 2 articulées à un maillon intermédiaire 3 et muni à leurs extrémités respectives libres 11 et 21 de moyens pour recevoir les extrémités libres d'un bracelet en cuir ou en métal, notamment d'un bracelet de montre. La branche 1 est munie de deux éléments femelles sous la forme de deux trous 14 et la branche 2 d'un téton lequel, en l'occurrence, est vissé sur la face de la branche 2. On pourrait avoir le contraire, c'est-à-dire qu'à la place de deux trous 14, avoir deux tétons et à la place du téton 22 avoir un trou.The clasp with folding clasp of FIG. 1 is composed of two curved branches 1, 2 articulated to an intermediate link 3 and provided at their respective free ends 11 and 21 with means for receiving the free ends of a leather or metal bracelet , including a watch strap. The branch 1 is provided with two female elements in the form of two holes 14 and the branch 2 with a stud which, in this case, is screwed on the face of the branch 2. We could have the opposite, it is that is to say that instead of two holes 14, have two studs and instead of stud 22 have a hole.
Dans le cas particulier représenté aux figures, on a choisi un maillon 3 présentant une surface plane A laquelle est, soit en contact avec la peau de l'utilisateur, soit avec le bracelet en fonction de la position relative des deux branches 1 et 2 et une surface concave B . La surface concave B est importante car elle permet d'obtenir lors de la fermeture de la boucle une surface continue sans angle ou surépaisseur gênante .In the particular case shown in the figures, a link 3 has been chosen having a flat surface A which is either in contact with the skin of the user, or with the bracelet depending on the relative position of the two arms 1 and 2 and a concave surface B. The concave surface B is important because it makes it possible to obtain, when the loop is closed, a continuous surface without any annoying angle or excess thickness.
Le maillon tel que représenté aux figures, nous avons une construction particulière. Le maillon est formé de trois éléments en forme de coin 31, 32 et 33, ces trois éléments pouvant être fabriqués indépendamment l'un de l'autre et par la suite assemblés, par exemple, par soudure ou être formés d'une seule pièce usinée.The link as shown in the figures, we have a particular construction. The link is formed by three wedge-shaped elements 31, 32 and 33, these three elements being able to be manufactured independently of one another and subsequently assembled, for example, by welding or to be formed in one piece machined.
Les deux éléments 31 et 32 sont disposés parallèlement et séparés par le troisième élément 33 qui est dirigé dans le sens opposé .The two elements 31 and 32 are arranged in parallel and separated by the third element 33 which is directed in the opposite direction.
Les parties des éléments 31 et 32 présentant la plus grande hauteur définissent l'une des extrémités du maillon munie des passages 34 et 35 pour l'articulation du maillon à la branche 2, tandis que l'élément 33 présente également sur sa partie présentant la plus grande hauteur un passage 36 pour son articulation à l'extrémité de la branche 1. L'extrémité 12 de la branche 1 se présente sous la forme d'un fer à cheval avec un passage longitudinal 13 pour l'articulation à l'élément 33 à travers, par exemple, un axe qui traverse le passage 13 du fer à cheval 12 et le passage 36 de l'élément 33.The parts of the elements 31 and 32 having the greatest height define one of the ends of the link provided with the passages 34 and 35 for the articulation of the link to the branch 2, while the element 33 also has on its part having the greater height a passage 36 for its articulation at the end of the branch 1. The end 12 of the branch 1 is in the form of a horseshoe with a longitudinal passage 13 for the articulation to the element 33 through, for example, an axis which crosses the passage 13 of the horseshoe 12 and the passage 36 of item 33.
La vue en plan de la figure 3 montre la configuration de cet élément particulier qui n'est qu'une exécution possible de l'invention.The plan view of FIG. 3 shows the configuration of this particular element which is only one possible embodiment of the invention.
En se référant maintenant aux autres figures, et notamment à la figure 4, on voit l'élément mâle 22 permettant en collaboration avec le trou 14 le verrouillage des deux branches 1 et 2 dans une première position dans laquelle le maillon 3 est disposé de sorte que sa surface A se trouve dans le prolongement et notamment dans la tangente de la courbe formée par la branche 1.Referring now to the other figures, and in particular to FIG. 4, we see the male element 22 allowing, in collaboration with the hole 14, the locking of the two branches 1 and 2 in a first position in which the link 3 is arranged so that its surface A is in the extension and in particular in the tangent of the curve formed by the branch 1.
La figure 5 est une vue en plan de la figure précédente, on voit la position relative des éléments.Figure 5 is a plan view of the previous figure, we can see the relative position of the elements.
A la figure 6 est représentée la boucle dans sa deuxième position, c'est-à-dire dans la position où le bracelet est le plus court, dans ce cas là l'élément mâle 22 se trouve dans le deuxième trou 14 de la branche 1 et le maillon 3 se trouve, notamment par sa surface A, dans le prolongement de la courbe formée par la branche 2. On voit dans les deux cas que la courbe formée par les deux branches superposées est harmonieuse et de même rayon de courbure et pratiquement continue ce qui n'apporte pas de désagrément à l'utilisateur. A la figure 7 nous avons également représenté une vue en plan de la figure 6.In Figure 6 is shown the loop in its second position, that is to say in the position where the bracelet is the shortest, in this case the male element 22 is located in the second hole 14 of the branch 1 and the link 3 is located, in particular by its surface A, in the extension of the curve formed by the branch 2. We see in both cases that the curve formed by the two superimposed branches is harmonious and has the same radius of curvature and practically continuous which does not bring any inconvenience to the user. In FIG. 7 we have also shown a plan view of FIG. 6.
En comparant les deux figures 5 et 6 on voit que dans un cas la branche 1 dépasse l'extrémité de la branche 2 et cette partie est en principe couverte par un élément décoratif qui est fixé soit sur le bracelet, soit sur l'élément 21 ce qui permet de cacher notamment le trou 14. Dans le cas de la figure 7, c'est-à-dire dans la deuxième position de la boucle, les deux extrémités des branches se superposent pratiquement, donc dans ce cas il n'y a rien à cacher, néanmoins l'élément décoratif est toujours là comme c'est l'habitude et comme on peut d'ailleurs le voir aussi bien dans le CH-A-571 327 ainsi que le CH 661 522.By comparing the two figures 5 and 6 we see that in one case the branch 1 exceeds the end of the branch 2 and this part is in principle covered by a decorative element which is fixed either on the bracelet or on the element 21 which allows in particular to hide the hole 14. In the case of FIG. 7, that is to say in the second position of the loop, the two ends of the branches practically overlap, so in this case there is no has nothing to hide, nevertheless the decorative element is still there as usual and as we can also see it as well in CH-A-571 327 as well as CH 661 522.
Le fait que la forme du maillon permet d'avoir une surface continue sans créer de surépaisseur inutile et sans gêne pour l'utilisateur et le fait que le verrouillage se fait en utilisant des éléments précis et disposés aux endroits prévus, notamment la position des deux trous assure un verrouillage stable sans possibilité que l'élément mâle glisse par exemple dans un trou oblong de manière intempestive .The fact that the shape of the link makes it possible to have a continuous surface without creating unnecessary extra thickness and without discomfort for the user and the fact that the locking is done using precise elements and arranged in the places provided, in particular the position of the two holes ensures stable locking without the possibility that the male element slides, for example in an oblong hole in an untimely manner.
Comme mentionné précédemment, d'autres formes d'exécution peuvent être prévues, c'est-à-dire que ce qui est important pour la forme du maillon 3 est la partie concave B qui permet d'épouser les surépaisseurs qui sont créées aux extrémités des articulations des deux branches et la surface plane A qui vient dans la prolongation de la tangente à la courbe formée par l'une ou l'autre des branches. As mentioned above, other embodiments can be provided, that is to say that what is important for the shape of the link 3 is the concave part B which allows to match the extra thicknesses which are created at the ends joints of the two branches and the flat surface A which comes in the extension of the tangent to the curve formed by one or the other of the branches.
