Wrist-watch comprising two straps (1, 2, 6) formed of leather (6) surrounding a flexible reinforcing member, the ends of these straps being on one side secured to the watch case and on the other side hingedly connected to a folding clasp (5) in such manner that the wrist-watch is forming a closed loop in the open position of said clasp, characterized by the fact that the flexible reinforcing member is consisting of two resilient blades (1, 2) having one end rigidly connected to the watch case (3').

Description

La présente invention a pour objet un bracelet-montre en cuir muni d'un fermoir pliant de manière à former une boucle fermée en position ouverte du fermoir.The present invention relates to a leather watch strap provided with a folding clasp so as to form a closed loop in the open position of the clasp.

De tels bracelets-montres sont très répandus. Ils sont munis d'un fermoir pliant en deux ou trois éléments souvent appelés fermoir portefeuille ou fermoir à boucle déployante. Le bracelet en cuir est généralement fixé à la montre au moyen d'une barrette.Such watch straps are very common. They are fitted with a folding clasp in two or three elements often called a wallet clasp or a folding clasp. The leather strap is generally attached to the watch by means of a strap.

Lorsqu'ils sont portés au poignet, ces bracelets forment un angle plus ou moins marqué et inesthétique avec la montre. En outre, il peut être parfois mal aisé d'introduire la main dans le bracelet-montre pour le fixer au poignet car la boucle formée par le bracelet-montre lorsque le fermoir est ouvert a parfois tendance à se refermer intempestivement.When worn on the wrist, these bracelets form a more or less marked and unsightly angle with the watch. In addition, it can sometimes be uneasy introduce your hand into the watch strap to fix it on your wrist because the loop formed by the watch strap when the clasp is open sometimes tends to close unexpectedly.

Enfin, il est nécessaire d'avoir un cuir suffisamment fort et épais pour résister à la traction lors de la fermeture du fermoir sur le poignet. Cette tension tend d'autre part à imprimer au cuir une forme rectiligne entre la montre et le fermoir.Finally, it is necessary to have a sufficiently strong and thick leather to resist traction when closing the clasp on the wrist. This tension, on the other hand, tends to give the leather a rectilinear shape between the watch and the clasp.

L'invention a pour but d'obvier à ces inconvénients.The object of the invention is to obviate these drawbacks.

Le bracelet-montre selon l'invention est caractérisé par le fait que le cuir entoure une armature constituée de deux lames flexibles dont une extrémité est rigidement solidaire de la montre et l'autre extrémité est articulée sur le fermoir.The wristwatch according to the invention is characterized in that the leather surrounds a frame made up of two flexible blades, one end of which is rigidly secured to the watch and the other end of which is articulated on the clasp.

Cette armature flexible rigidement solidaire de la boite assure simultanément la résistance à la traction du bracelet, le maintien en position ouverte de la boucle formée par le bracelet-montre lorsque le fermoir est ouvert et une courbure harmonieuse du cuir sans coude au départ de la boite. L'armature est choisie de préférence très mince et très flexible de manière à n'opposer qu'une très légère résistance lors de la fermeture du fermoir. Compte tenu de cette très faible épaisseur, la lame n'a pas, comme on pourrait le croire, pour effet d'augmenter l'épaisseur du bracelet, mais au contraire sa résistance permet d'utiliser un cuir très mince de telle sorte que l'épaisseur finale du bracelet est inférieure à celle d'un bracelet en cuir conventionnel. Il est donc possible de réaliser un bracelet-montre résistant présentant un aspect léger et fin.This flexible frame rigidly secured to the box simultaneously ensures the tensile strength of the bracelet, the maintenance in the open position of the loop formed by the watch strap when the clasp is open and a harmonious curvature of the leather without elbow at the start of the box. . The frame is preferably chosen to be very thin and very flexible so as to offer only a very slight resistance when the clasp is closed. Given this very small thickness, the blade does not, as one might believe, have the effect of increasing the thickness of the bracelet, but on the contrary its resistance allows the use of very thin leather so that the the final thickness of the bracelet is less than that of a bracelet made of conventional leather. It is therefore possible to make a resistant watch bracelet with a light and thin appearance.

Le dessin annexé représente, à titre d'exemple, une forme d'exécution du bracelet-montre selon l'invention.

  • La figure 1 en représente une vue de profil, fermoir ouvert.
  • La figure 2 représente l'âme du bracelet.
  • La figure 3 est un détail montrant la fixation du bracelet à la boite de montre.
  • La figure 4 est un détail montrant l'attache du bracelet au fermoir.
The accompanying drawing shows, by way of example, an embodiment of the watch strap according to the invention.
  • Figure 1 shows a side view, open clasp.
  • Figure 2 shows the soul of the bracelet.
  • Figure 3 is a detail showing the attachment of the strap to the watch case.
  • Figure 4 is a detail showing the attachment of the bracelet to the clasp.

L'âme du bracelet est constituée de deux lames 1 et 2 en bronze béryllium d'une épaisseur de 0,15 mm. A l'une de leurs extrémités les lames sont encastrées et soudées dans un anneau métallique 3, par exemple en laiton, faisant partie de la boite de montre (fig.3). L'autre extrémité des lames 1 et 2 est repliée sur elle-même de manière à former un attache 4 de forme tubulaire pour la fixation articulée du bracelet sur le fermoir 5. Les lames élastiques 1 et 2 sont entourées par le cuir du bracelet. Le cuir est collé sur les lames.The soul of the bracelet consists of two blades 1 and 2 in beryllium bronze with a thickness of 0.15 mm. At one of their ends, the blades are embedded and welded in a metal ring 3, for example in brass, forming part of the watch case (fig. 3). The other end of the blades 1 and 2 is folded back on itself so as to form a fastener 4 of tubular shape for the articulated fixing of the bracelet on the clasp 5. The elastic blades 1 and 2 are surrounded by the leather of the bracelet. The leather is glued to the blades.

Le fermoir 5 est du type à boucle déployante ou double portefeuille et comporte une partie centrale 7 aux extrémités de laquelle sont articulés deux bras 8 et 9 qui viennent se rabattre et se verrouiller sur la partie centrale 7. Les attaches du bracelet au fermoir sont cachées par une plaque de couverture 10.The clasp 5 is of the folding clasp or double wallet type and has a central part 7 at the ends of which are articulated two arms 8 and 9 which fold back and lock on the central part 7. The strap attachments to the clasp are hidden by a cover plate 10.

En raison de l'encastrement des lames métalliques 1 et 2 et de leur élasticité, le bracelet en position ouverte, a tendance à rester ou revenir dans la position déployée représentée à la figure 1. En position complètement détendue, les lames 1 et 2 peuvent présenter une courbure initiale plus ou moins marquée, de telle sorte que la force élastique soit juste suffisante pour maintenir le bracelet en position déployée tel que représenté à la figure 1, sans toutefois exercer une traction trop forte sur le fermoir, ni supporter une sollicitation trop forte au niveau de l'encastrement. Ce déploiement naturel du bracelet facilite la mise en place de la montre-bracelet sur le poignet, ainsi que son enlèvement. L'âme élastique assure en outre un maintien et une courbure harmonieuse du bracelet cuir.Due to the embedding of the metal blades 1 and 2 and their elasticity, the bracelet in the open position, tends to remain or return to the deployed position shown in Figure 1. In the fully relaxed position, the blades 1 and 2 can have a more or less marked initial curvature, so that the elastic force is just sufficient to maintain the bracelet in the deployed position as shown in FIG. 1, without however exerting too strong a pull on the clasp, nor enduring too much stress strong at the level of the installation. This natural deployment of the bracelet facilitates the positioning of the wristwatch on the wrist, as well as its removal. The elastic core also ensures a support and a harmonious curvature of the leather strap.

De nombreuses variantes d'exécution sont bien entendu possibles sans sortir du cadre de l'invention. Par exemple, les lames métalliques pourraient être en un autre métal, par exemple en acier et elles pourraient être fixées rigidement d'une autre manière à la boite, en particulier à la carrure, par exemple au moyen de vis. Les attaches 4 pourraient être rapportées. Les lames flexibles peuvent également être en un matériau non métallique, par exemple en matière synthétique telle que du Nylon (marque déposée). Une lame en matière synthétique a pour avantage de pouvoir être fabriquée par moulage et de permettre une meilleure adhérence, par collage, du cuir sur la lame.Many alternative embodiments are of course possible without departing from the scope of the invention. For example, the metal blades could be made of another metal, for example steel, and they could be rigidly fixed in another way to the case, in particular to the middle part, for example by means of screws. Fasteners 4 could be added. The flexible blades can also be made of a non-metallic material, for example synthetic material such as nylon (registered trademark). A plastic blade has the advantage of being able to be produced by molding and of allowing better adhesion, by gluing, of the leather on the blade.
