La partie centrale du fermoir est constituée de deux pièces (9, 10) dont la position relative est réglable et peut être fixée par des vis (14, 15, 16). Les bras (4, 5) articulés aux extrémités de la partie centrale sont munis de joues latérales (17, 18; 19, 20) par lesquelles ils viennent se fixer à cran sur la pièce la plus large (9) de la partie centrale du fermoir. Les extrémités des deux bras (4, 5) auxquelles sont attachés les brins du bracelet (8, 8a), ainsi que l'espace existant, le cas échéant, entre ces extrémités, en position fermée du fermoir, sont cachées par une plaque de couverture (21) pouvant recevoir un décor.The central part of the clasp is made up of two parts (9, 10) whose relative position is adjustable and can be fixed by screws (14, 15, 16). The arms (4, 5) articulated at the ends of the central part are provided with lateral cheeks (17, 18; 19, 20) by which they are fixed to the notch on the widest part (9) of the central part of the clasp. The ends of the two arms (4, 5) to which the strands of the bracelet (8, 8a) are attached, as well as the space, if any, between these ends, in the closed position of the clasp, are hidden by a plate of cover (21) capable of receiving a decoration.

Description

La présente invention a pour objet un fermoir de bracelet à boucle déployante comprenant une partie centrale aux extrémités de laquelle sont articulés deux bras aux autres extrémités desquels sont attachés les brins du bracelet, ces bras venant se rabattre et se fixer sur la partie centrale en position fermée du fermoir.The subject of the present invention is a bracelet clasp with a folding clasp comprising a central part at the ends of which are articulated two arms at the other ends of which the strands of the bracelet are attached, these arms coming to fold down and to be fixed on the central part in position. closed from the clasp.

Un fermoir de ce type est décrit dans le brevet CH.596.793. Dans ce fermoir, les deux bras articulés viennent se fixer à cran par leurs extrémités à une pièce prévue au centre de la partie centrale. Une autre exécution est décrite dans le brevet CH.471.556. Les fermoirs de ce type ont pour avantage d'être bien centrés sur le bracelet donnant au bracelet, notamment aux bracelets de montres, un aspect harmonieux et équilibré. Ces fermoirs ont toutefois pour inconvénient de ne pas être réglables, car les extrémités des deux bras articulées doivent se rejoindre au milieu de la partie centrale, d'une part pour leur fixation et d'autre part pour des raisons d'esthétique, notamment pour cacher la partie centrale du fermoir.A clasp of this type is described in patent CH.596.793. In this clasp, the two articulated arms are fixed to the notch by their ends to a part provided in the center of the central part. Another embodiment is described in patent CH.471.556. The clasps of this type have the advantage of being well centered on the bracelet giving to the bracelet, in particular to watch straps, a harmonious and balanced appearance. However, these clasps have the drawback of not being adjustable, since the ends of the two articulated arms must meet in the middle of the central part, on the one hand for their attachment and on the other hand for aesthetic reasons, in particular for hide the central part of the clasp.

Le but de l'invention est précisément de réaliser un fermoir du type susmentionné présentant des possibilités de réglage de sa longueur pour son adaptation au poignet du porteur.The object of the invention is precisely to produce a clasp of the aforementioned type having possibilities of adjusting its length for its adaptation to the wrist of the wearer.

A cet effet, le fermoir de bracelet selon l'invention est caractérisé par le fait que la partie centrale est constituée de deux pièces susceptibles d'être déplacées longitudinalement l'une dans l'autre, des moyens de fixation étant prévus pour fixer ensemble les deux pièces dans la position relative désirée et qu'au moins l'un des bras articulés présente des joues latérales par lesquelles ce bras vient se fixer à cran sur les côtés de la pièce la plus large de la partie centrale en position fermée, une plaquette de couverture étant prévue à l'extrémité attachée au bracelet de l'un des bras articulés pour couvrir les extrémités des bras attachées au bracelet et, le cas échéant, l'espace séparant ces extrémités, en position fermée.To this end, the bracelet clasp according to the invention is characterized in that the central part consists of two parts capable of being displaced longitudinally one inside the other, fixing means being provided for fixing together the two pieces in the desired relative position and that at least one of the articulated arms has lateral cheeks by which this arm is fixed to the notches on the sides of the widest piece of the central part in the closed position, a plate cover being provided at the end attached to the bracelet of one of the articulated arms to cover the ends of the arms attached to the bracelet and, if necessary, the space separating these ends, in the closed position.

La fixation latérale des bras articulés sur la partie centrale permet de les fixer en un point quelconque de la pièce la plus large de la partie centrale. L'utilisation d'une plaquette de couverture résout le problème de l'espace se formant entre les extrémités des bras articulés. Cette plaquette de couverture peut en outre porter divers décors, par exemple celui d'une boucle, ce qui permet de donner les aspects les plus divers au fermoir.The lateral fixing of the articulated arms on the central part makes it possible to fix them at any point in the widest part of the central part. The use of a cover plate solves the problem of the space forming between the ends of the articulated arms. This cover plate can also carry various decorations, for example that of a loop, which makes it possible to give the most different aspects to the clasp.

Le dessin annexé représente, à titre d'exemple, deux formes d'exécution du fermoir selon l'invention.The accompanying drawing shows, by way of example, two embodiments of the clasp according to the invention.

  • La figure 1 est une vue en plan du fermoir en position fermée d'une première forme d'exécutionFigure 1 is a plan view of the clasp in the closed position of a first embodiment
  • La figure 2 est une vue de profil du même fermoir en position à moitié ouverte.Figure 2 is a side view of the same clasp in the half open position.
  • La figure 3 représente le même fermoir en position ouverte, vu de dessous, selon la direction A, figure 2.FIG. 3 represents the same clasp in the open position, seen from below, in direction A, FIG. 2.
  • La figure 4 représente une vue en plan, fermée, d'un fermoir selon une seconde forme d'exécution.Figure 4 shows a plan view, closed, of a clasp according to a second embodiment.
  • La figure 5 est une vue de profil du même fermoir en position partiellement ouverte.Figure 5 is a side view of the same clasp in the partially open position.
  • La figure 6 représente le même fermoir en position complètement ouverte, selon la direction 8, figure 5.FIG. 6 represents the same clasp in the fully open position, in the direction 8, FIG. 5.

Conformément aux fermoirs de ce type, le fermoir représenté comprend une partie centrale arquée 1 à chacune des extrémités 2 et 3 de laquelle sont articulés deux bras 4 et 5 qui viennent se rabattre sur la partie centrale 1. Aux extrémités 6 et 7 des bras 4 et 5 sont fixées respectivement les extrémités des brins 8 et 8a d'un bracelet, par exemple un bracelet en cuir.In accordance with clasps of this type, the clasp shown comprises an arcuate central part 1 at each of the ends 2 and 3 of which are articulated two arms 4 and 5 which are folded over the central part 1. At the ends 6 and 7 of the arms 4 and 5 are fixed respectively the ends of the strands 8 and 8a of a bracelet, for example a leather bracelet.

La partie centrale 1 est constituée d'une plaquette 9 présentant un profil en U entre les ailes 9a et 9b de laquelle est engagée une plaquette 10 présentant la même courbure que la plaquette 9 et munie de trois rangées 11,12 et 13 de trous taraudés dans lesquels viennent se visser trois vis 14,15, et 16 noyées dans la plaquette 9 et retenues par cette leur tête dans cette plaquette. Il est prévu trois vis pour assurer une bonne rigidité de la fixation, mais en principe une seule vis suffirait. Il est ainsi possible d'adapter la longueur du bracelet au poignet du porteur en vissant les vis 14, 15 et 16 dans les trous appropriés des rangées 11,12 et 13, ceci sans rompre la symétrie du bracelet, c'est-à-dire la position centrée du fermoir sur le bracelet.The central part 1 consists of a plate 9 having a U-shaped profile between the wings 9a and 9b from which is engaged a plate 10 having the same curvature as the plate 9 and provided with three rows 11, 12 and 13 of tapped holes in which are screwed three screws 14,15, and 16 embedded in the plate 9 and retained by this their head in this plate. Three screws are provided to ensure good rigidity of the fixing, but in principle a single screw would suffice. It is thus possible to adapt the length of the bracelet to the wrist of the wearer by screwing the screws 14, 15 and 16 into the appropriate holes of the rows 11, 12 and 13, this without breaking the symmetry of the bracelet, that is to say tell the centered position of the clasp on the bracelet.

La fixation des deux bras 4 et 5 sur la partie centrale 1 en position fermée est assurée par clipsage, par deux paires de joues 17 et 18, respectivement 19 et 20 qui viennent pincer élastiquement les ailes 9a et 9b de la pièce 9.The two arms 4 and 5 are fixed to the central part 1 in the closed position by clipping, by two pairs of cheeks 17 and 18, respectively 19 and 20 which elastically pinch the wings 9a and 9b of the part 9.

Contrairement aux fermoirs à boucle déployante connus, non réglables, dans lesquels les deux extrémités des bras articulées se rejoignent au centre du fermoir, dans la présente exécution les extrémités de ces bras sont à une distance variable en fonction de la position relative des pièces 9 et 10. Le problème posé par cette distance variable a été résolu au moyen d'une plaque de couverture 21 munie de deux joues 22 et 23 qui viennent se fixer à cran, par un léger crantage, sur les extrémités de l'axe 7 de la fixation du brin de bracelet 8 au fermoir, assurant ainsi une retenue supplémentaire et une bonne application de la plaque de couverture 21 sur le bracelet. La plaque 21 se prête particulièrement bien à recevoir une décoration, en particulier un élément présentant le même aspect que le bracelet et donnant à la plaque 21 l'aspect d'une boucle légère. Le bracelet peut être fixé au fermoir par tout moyen connu tel que axe à vis, barrette à ressort, etc.Unlike known folding clasps, non-adjustable, in which the two ends of the articulated arms meet at the center of the clasp, in the present embodiment the ends of these arms are at a variable distance depending on the relative position of the parts 9 and 10. The problem posed by this variable distance was solved by means of a cover plate 21 provided with two cheeks 22 and 23 which come attach to the notch, by a slight notching, on the ends of the axis 7 of the attachment of the bracelet strand 8 to the clasp, thus ensuring additional retention and good application of the cover plate 21 on the bracelet. The plate 21 is particularly suitable for receiving a decoration, in particular an element having the same appearance as the bracelet and giving the plate 21 the appearance of a light loop. The bracelet can be attached to the clasp by any known means such as a screw pin, spring bar, etc.

Les deux articulations du fermoir sont à gond.The two joints of the clasp are hinged.

Pour ouvrir le fermoir il suffit de soulever la plaque de couverture 21 et de tirer ensuite sur le bras 5.To open the clasp, simply lift the cover plate 21 and then pull on the arm 5.

Selon une variante non représentée, le positionnement relatif des parties 9 et 10 du fermoir n'est pas réalisé au moyen de vis, mais au moyen de crans ménagés d'une part à l'intérieur des ailes 9a et 9b et d'autre part sur les côtés de la plaquette 10. Le déplacement d'un cran à l'autre se fait à force, une élasticité supplémentaire pouvant être donnée à la partie 10 par une fente longitudinale d'élasticité. Une autre solution consisterait _à prévoir des crans uniquement dans les ailes 9a et 9b et à monter un petit excentrique rotatif dans la partie 10, cet excentrique étant muni de dents qui viennent s'engager dans les crans de la partie 9. Cette partie 9 pourrait être de forme tubulaire ou tubulaire fendue, les ailes 9a et 9b présentant un coude perpendiculaire dirigé vers l'intérieur du fermoir.According to a variant not shown, the relative positioning of the parts 9 and 10 of the clasp is not achieved by means of screws, but by means of notches formed on the one hand inside the wings 9a and 9b and on the other hand on the sides of the plate 10. The displacement from one notch to the other is done by force, an additional elasticity can be given to the part 10 by a longitudinal elasticity slot. Another solution would consist in _providing notches only in the wings 9a and 9b and mounting a small rotary eccentric in the part 10, this eccentric being provided with teeth which come to engage in the notches of the part 9. This part 9 could be of tubular or split tubular shape, the wings 9a and 9b having a perpendicular bend directed towards the inside of the clasp.

Une seconde forme d'exécution est représentée aux figures 4 à 6. Les éléments repris sans modification de la première forme d'exécution sont désignés par les mêmes références.A second embodiment is shown in Figures 4 to 6. The elements taken up without modification of the first embodiment are designated by the same references.

Dans cette forme d'exécution la partie centrale est constituée d'une première partie 24 présentant deux bras rectangulaires parallèles 25 et 26, légèrement incurvés selon la courbure du bracelet, et dont les côtés intérieurs, regard l'une de l'autre, sont conformés en glissière 27 à 28, le fond de ces glissières étant muni de dents ou de crans de profil triangulaire. L'autre partie 29 présente un seul bras central 30 muni de chaque côté d'une denture 31, respectivement 32, aux dents de profil triangulaire. Cette partie 30 est engagée dans les glissières 27 et 28, de telle sorte que les dents des dentures 31 et 32 sont engagées dans les dents ou crans de ces glissières. Les dents des dentures 31 et 32 peuvent toutefois passer par dessus les dents des glissières 27 et 28 en écartant élastiquement les bras 25 et 26, lorsqu'on exerce une traction ou une poussée suffisante sur la partie 29, en retenant la partie 24. Le bras 5, muni de ses joues 19 et 20, est articulé à la partie 24, tandis qu'un bras 33 est articulé d'une part à la partie 29 et d'autre part à la plaque de couverture 21. Ce bras 33 présente deux nervures centrales longitudinales 34 et 35, dont les extrémités présentent un petit talon, dirigé vers l'extérieur. De son côté la partie 29 présente une découpe centrale longitudinale 36 dont la largeur est légèrement inférieure à la largeur totale maximale de l'ensemble des deux nervures 34 et 35.In this embodiment, the central part consists of a first part 24 having two parallel rectangular arms 25 and 26, slightly curved according to the curvature of the bracelet, and whose inner sides, facing one another, are shaped into a slide 27 to 28, the bottom of these slides being provided with teeth or notches of triangular profile. The other part 29 has a single central arm 30 provided on each side with a toothing 31, respectively 32, with teeth of triangular profile. This part 30 is engaged in the slides 27 and 28, so that the teeth of the teeth 31 and 32 are engaged in the teeth or notches of these slides. The teeth of the teeth 31 and 32 can however pass over the teeth of the slides 27 and 28 by elastically spreading the arms 25 and 26, when a sufficient traction or thrust is exerted on the part 29, by retaining the part 24. arm 5, provided with its cheeks 19 and 20, is articulated to part 24, while an arm 33 is articulated on the one hand to part 29 and on the other hand to the cover plate 21. This arm 33 has two longitudinal central ribs 34 and 35, the ends of which have a small heel, directed outwards. For its part the part 29 has a longitudinal central cutout 36 whose width is slightly less than the maximum total width of the assembly of the two ribs 34 and 35.

Lorsqu'on ferme le fermoir, on rabat tout d'abord le bras 5 sur la partie 24. Les joues 19 et 20 ont alors non seulement pour fonction de fixer à cran le bras 5 sur la partie 24, mais d'empêcher l'écartement des bras 25 et 26, c'est-à-dire d'empêcher un déplacement du bras 30 relativement aux bras 25 et 26. On rabat ensuite le bras 33 sur la partie 29. Les nervures 34 et 35 viennent s'engager à force, en fléchissant légèrement, dans la découpe 36 pour s'y fixer à cran. Quant à la plaque de couverture 21 elle vient à nouveau se fixer par ses joues 22 et 23 sur l'axe d'articulation 7.When the clasp is closed, the arm 5 is first folded down on the part 24. The cheeks 19 and 20 then have not only the function of fixing the arm 5 on the notch 24 on the notch, but of preventing separation of the arms 25 and 26, that is to say to prevent movement of the arm 30 relative to the arms 25 and 26. The arm 33 is then folded over the part 29. The ribs 34 and 35 engage to force, slightly bending, in the cutout 36 to fix it to the notch. As for the cover plate 21 it is again fixed by its cheeks 22 and 23 on the hinge pin 7.
