Abstract

The bracelet clasp has a base (1) and a leaf (2) which can fold down on the base. The leaf and the base are fastened together at their ends by a spindle (3). The other end of the leaf has a fixing (6) for the bracelet's first link (8). A cover (10) locks the leaf in the folded down position on the base. The cover is mounted on the base by a spindle (11) which allows it to tip laterally relative to the bracelet longitudinal direction. A push button (12) in the base locks the cover on the base. A spring (13) supported under the cover raises the cover when a pressure is exerted on the push button to open the clasp. The spring has a ball (14) mounted in a blind tube (15) forced into the base. The tube top is crimped so as to retain the ball. A return spring (17) is placed between the ball and the tube bottom.

Description

La présente invention est relative à un fermoir de bracelet du type à boucle déployante comprenant une base, au moins une première lame susceptible de se rabattre sur la base, la base et la première lame étant attachées ensemble par l'une de leurs extrémités au moyen d'une première articulation, l'autre extrémité de la première lame présentant des moyens de fixation d'un premier brin que présente le bracelet, un couvercle verrouillant la première lame en position rabattue sur la base, ledit couvercle étant monté sur ladite base au moyen d'une articulation pour effectuer un basculement latéral par rapport à la direction longitudinale du bracelet, et un poussoir monté dans la base pour verrouiller ledit couvercle sur ladite base.The present invention relates to a bracelet clasp of the folding clasp type comprising a base, at least one first blade capable of being folded over the base, the base and the first blade being attached together by one of their ends by means a first articulation, the other end of the first blade having means for fixing a first strand that has the bracelet, a cover locking the first blade in the folded position on the base, said cover being mounted on said base at means of an articulation for effecting a lateral tilting with respect to the longitudinal direction of the bracelet, and a pusher mounted in the base to lock said cover on said base.

Un fermoir répondant à la définition générique donnée ci-dessus est connue par exemple des documents CH-A-666 165 et EP-A-0 319 461.A clasp meeting the generic definition given above is known for example from documents CH-A-666 165 and EP-A-0 319 461.

Le document CH-A-666 165 décrit un fermoir comprenant une base et une lame susceptible de se rabattre sur la base. La base et la lame sont articulées l'une à l'autre par un gond et maintenues en position fermée par un cran. Afin d'éviter toute ouverture intempestive du fermoir, un couvercle ou pont est fixé latéralement par un second gond sur la base. Le couvercle est apte à être rabattu par dessus la lame et le brin du bracelet qui lui est attaché. Une fois rabattu, le couvercle est verrouillé par un cran.Document CH-A-666 165 describes a clasp comprising a base and a blade capable of being folded over the base. The base and the blade are hinged to each other by a hinge and held in the closed position by a notch. In order to avoid any untimely opening of the clasp, a cover or bridge is fixed laterally by a second hinge on the base. The cover is able to be folded over the blade and the strand of the bracelet attached to it. Once folded down, the cover is locked by a notch.

Le document EP-A-0 319 461 décrit quant à lui un même type de fermoir comportant une base et deux lames rabattantes. Un couvercle est articulé sur la base et susceptible de se rabattre latéralement sur celle-ci par rapport à la direction longitudinale du bracelet. L'extremité de chaque brin est liée à une lame par une articulation en escalier. En position rabattue des lames, et lorsque le couvercle est rabattu sur la base, ce couvercle est tenu à cran sur cette base en même temps qu'il coince une partie de l'articulation en escalier de sorte qu'on empêche toute ouverture intempestive du fermoir.Document EP-A-0 319 461 describes the same type of clasp comprising a base and two folding blades. A cover is articulated on the base and capable of being folded laterally on the latter relative to the longitudinal direction of the bracelet. The end of each strand is linked to a blade by a staircase joint. When the blades are folded down, and when the cover is folded down on the base, this cover is held notch on this base at the same time as it wedges part of the staircase joint so that any untimely opening of the clasp is prevented.

Dans un cas comme dans l'autre, on observera que le couvercle est maintenu à cran sur la base. Cela signifie que pour le libérer et donc pour ouvrir le fermoir, il est nécessaire d'exercer un effort digital sur le couvercle. Comme le constructeur désire assurer une très bonne tenue du couvercle, à la vente du produit et après plusieurs années d'usage, il fera en sorte que le crantage soit fortement résistant. Ceci oblige l'usager d'exercer une grande force sur le couvercle au risque de se faire mal, voire de se casser un ongle. Dans le cas du document EP-A-0 319 461 cependant, il est prévu dans une troisième forme d'exécution, un fermoir muni d'un poussoir que l'on peut actionner pour libérer le couvercle. On fera remarquer cependant que la pression sur le poussoir ne soulève pas le couvercle et doit donc s'accompagner d'un geste digital de soulèvement, ce qui complique la manoeuvre d'ouverture.In either case, it will be observed that the cover is kept notched on the base. This means that to release it and therefore to open the clasp, it is necessary to exert a digital force on the cover. As the manufacturer wishes to ensure a very good hold of the cover, at the sale of the product and after several years of use, he will make sure that the notching is highly resistant. This forces the user to exert a great force on the cover at the risk of hurting themselves, or even breaking a fingernail. In the case of document EP-A-0 319 461, however, there is provided in a third embodiment, a clasp provided with a pusher which can be actuated to release the cover. Note however that the pressure on the pusher does not lift the cover and must therefore be accompanied by a digital lifting gesture, which complicates the opening operation.

Pour éviter ces inconvénients, le fermoir de l'invention est remarquable en ce sens qu'il nécessite très peu d'effort pour libérer le couvercle puisqu'il comporte des moyens de soulèvement instantané dudit couvercle quand on exerce une pression sur le poussoir pour ouvrir le fermoir.To avoid these drawbacks, the clasp of the invention is remarkable in that it requires very little effort to release the cover since it comprises means for instantaneous lifting of said cover when pressure is applied to the pusher to open the clasp.

Les avantages qu'apporte cette disposition particulière selon l'invention seront apparents à la lecture de la description qui va suivre, description qui s'appuie, à titre d'exemple, sur le dessin dans lequel :

  • La figure 1 est une vue en perspective du fermoir de l'invention présenté en position ouverte;
  • la figure 2 est une coupe longitudinale du fermoir selon la ligne II-II de la figure 1, le fermoir étant présenté en position fermée;
  • la figure 3 est une coupe transversale du fermoir selon la ligne III-III de la figure 1, le fermoir étant présenté en position fermée;
  • la figure 4 est une vue de dessus du fermoir selon la flèche IV de figure 1, le fermoir étant présenté en position fermée, et
  • la figure 5 montre un exemple de moyens de soulèvement du couvercle présenté dans les figures précédentes.
The advantages of this particular arrangement according to the invention will become apparent on reading the description which follows, a description which is based, by way of example, on the drawing in which:
  • Figure 1 is a perspective view of the clasp of the invention presented in the open position;
  • Figure 2 is a longitudinal section of the clasp along the line II-II of Figure 1, the clasp being presented in the closed position;
  • Figure 3 is a cross section of the clasp along line III-III of Figure 1, the clasp being presented in the closed position;
  • FIG. 4 is a top view of the clasp according to arrow IV of FIG. 1, the clasp being presented in the closed position, and
  • FIG. 5 shows an example of means for lifting the cover presented in the previous figures.

Comme on le voit sur les figures 1, 2 et 3, ce fermoir comporte deux lames rabattables sur la base, mais pourrait n'en comporter qu'une seule.As seen in Figures 1, 2 and 3, this clasp has two folding blades on the base, but could have only one.

Dans le cas où ce fermoir ne comportait qu'une seule lame, un brin du bracelet serait directement articulé sur la base, par exemple à gauche de la figure, alors que l'autre brin serait articulé à l'extrémité de la seule lame existante, comme représenté à droite de la figure. Ainsi l'invention peut-elle convenir à des fermoirs comportant une ou deux lames, la description qui en sera faite maintenant s'appuyant sur un fermoir à deux lames.In the case where this clasp had only one blade, one strand of the bracelet would be directly articulated on the base, for example on the left of the figure, while the other strand would be articulated at the end of the only existing blade , as shown on the right of the figure. Thus, the invention can it be suitable for clasps comprising one or two blades, the description which will be made of them now based on a clasp with two blades.

Le fermoir comporte une base 1 incurvée pour s'adapter à la courbure du poignet qui le porte. Il comporte en outre une première lame 2 et une seconde lame 4 susceptible chacune de se rabattre sur la base 1. La base 1 et la première lame 2 sont attachées ensemble par l'une de leurs extrémités au moyen d'une première articulation 3. L'autre extrémité de la première lame 2 présente des moyens de fixation d'un premier brin ou maillon 8 composant le bracelet. De façon analogue, la base 1 et la seconde lame 4 sont attachées ensemble par l'une de leurs extrémités au moyen d'une seconde articulation 5. L'autre extrémité de la seconde lame 4 présente des moyens de fixation d'un second brin ou maillon 9 composant le bracelet. Le fermoir comporte encore un couvercle 10 comme le montre bien la figure 3, ce couvercle étant monté sur la base 1 au moyen d'une articulation 11 pour effectuer un basculement latéral par rapport à la direction longitudinale du bracelet. Ce couvercle verrouille les première et seconde lames 2 et 4 sur la base 1, comme cela sera expliqué en détail plus bas. Le fermoir comporte encore un poussoir 12 monté dans la base 1 pour verrouiller le couvercle 10 sur la base 1 selon des explications qui seront également données plus loin.The clasp has a curved base 1 to adapt to the curvature of the wrist which carries it. It further comprises a first blade 2 and a second blade 4 each capable of being folded over the base 1. The base 1 and the first blade 2 are attached together by one of their ends by means of a first articulation 3. The other end of the first blade 2 has means for fixing a first strand or link 8 making up the bracelet. Similarly, the base 1 and the second blade 4 are attached together by one of their ends by means of a second articulation 5. The other end of the second blade 4 has means for fixing a second strand or link 9 making up the bracelet. The clasp also has a cover 10 as shown in FIG. 3, this cover being mounted on the base 1 by means of a hinge 11 to effect lateral tilting relative to the longitudinal direction of the bracelet. This cover locks the first and second blades 2 and 4 on the base 1, as will be explained in detail below. The clasp also includes a pusher 12 mounted in the base 1 to lock the cover 10 on the base 1 according to explanations which will also be given later.

Ce qui caractérise principalement la présente invention consiste à disposer sur le fermoir des moyens de soulèvement instantané 13 du couvercle 10 quand on exerce une pression sur le poussoir 12 pour ouvrir le fermoir. Ces moyens 13 apparaissent sur toutes les figures présentes.What mainly characterizes the present invention consists in having on the clasp instant lifting means 13 of the cover 10 when pressure is exerted on the pusher 12 to open the clasp. These means 13 appear in all the figures present.

Ces moyens peuvent être mis en oeuvre de différentes façons. On peut imaginer généralement un élément à ressort monté dans la base 1 et s'appuyant sous le couvercle 10. Ce pourrait être par exemple une simple lame élastique couchée dans une rainure pratiquée dans la base.These means can be implemented in different ways. One can generally imagine a spring element mounted in the base 1 and pressing under the cover 10. This could for example be a simple elastic blade lying in a groove made in the base.

Les figures 1 à 5 montrent que la préférence à été donnée à une bille 14. Comme le montre bien le dessin de détail de la figure 5, la bille 14 est montée dans un tube borgne 15. Le haut du tube 15 comporte un sertissage 16 qui retient la bille contre la force d'un ressort à boudin 17. Le ressort est situé entre la bille 14 et le fond 18 du tube 15. Quand le fermoir est en position de fermeture, le couvercle exerce une pression sur la bille 14 qui comprime le ressort 17 comme le montrent bien les figures 2 et 3. Dès qu'on libère le couvercle 10 en pressant sur le poussoir 12, la bille sert d'éjecteur au couvercle qui se soulève (voir figure 3). Il n'y a dès lors pas de difficulté à faire basculer le couvercle dans la position totalement ouverte comme il est représenté sur la figure 1. Ce basculement a lieu donc sans qu'il soit nécessaire de vaincre l'effort de retenue d'un système à cran qui équipe les fermoirs des documents cités. De plus, on comprendra que si la force du ressort est assez grande, la bille pourra faire basculer entièrement le couvercle sans que le porteur n'ait à intervenir.Figures 1 to 5 show that preference has been given to a ball 14. As shown in the detail drawing of Figure 5, the ball 14 is mounted in a blind tube 15. The top of the tube 15 has a crimp 16 which retains the ball against the force of a coil spring 17. The spring is located between the ball 14 and the bottom 18 of the tube 15. When the clasp is in the closed position, the cover exerts pressure on the ball 14 which compresses the spring 17 as shown in FIGS. 2 and 3. As soon as the cover 10 is released by pressing on the plunger 12, the ball acts as an ejector for the cover which lifts (see FIG. 3). There is therefore no difficulty in tilting the cover into the fully open position as shown in FIG. 1. This tilting therefore takes place without it being necessary to overcome the retaining force of a notch system which equips the clasps of the cited documents. In addition, it will be understood that if the force of the spring is large enough, the ball can completely tilt the cover without the wearer having to intervene.

Tel que représenté aux figures 3 et 4, le tube 15, enfermant la bille 14, remplit une autre fonction que celle de moyens de soulèvement. En effet, les figures montrent que ce tube traverse un trou oblong 19 pratiqué dans le poussoir 12. Le tube 15, chassé dans la base 1 et dans un trou 35 de cette base, sert donc à limiter la course du poussoir d'une part en l'empêchant de sortir de la base 1 et d'autre part en limitant son enfoncement dans ladite base.As shown in Figures 3 and 4, the tube 15, enclosing the ball 14, fulfills a function other than that of lifting means. Indeed, the figures show that this tube passes through an oblong hole 19 made in the pusher 12. The tube 15, driven into the base 1 and into a hole 35 in this base, therefore serves to limit the stroke of the pusher on the one hand by preventing it from leaving the base 1 and on the other hand by limiting its insertion into said base.

Le poussoir 12 du fermoir est une plaque montée coulissante dans la base sous l'action de la force de rappel d'un ressort 20, comme montré sur les figures 3 et 4. A l'opposé du ressort 20, cette plaque 12 comporte une languette 30 émergeant de la base et sur laquelle s'exerce la pression du doigt. Comme on le voit sur les figures 1, 3 et 4, la plaque 12 comprend deux bords 21 en biseau (un seul bord en biseau serait suffisant). De plus, le bord latéral du couvercle 10 qui est opposé à l'articulation 11 présente deux crans 22 (un seul serait également suffisant). Comme cela est bien visible sur la figure 3, lorsque le couvercle 10 est fermé, le biseau 21 de la plaque 12 vient s'accrocher sous le cran 22 du couvercle 10. Lorsqu'on exerce une pression sur la languette 30 de la plaque 12, le bord 21 en biseau se désengage du cran 22 et le couvercle 10 se soulève instantanément sous l'effet de la force d'éjection exercée par le ressort 17 agissant sur la bille 14.The pusher 12 of the clasp is a plate mounted to slide in the base under the action of the return force of a spring 20, as shown in FIGS. 3 and 4. Opposite the spring 20, this plate 12 has a tongue 30 emerging from the base and on which the finger pressure is exerted. As seen in Figures 1, 3 and 4, the plate 12 includes two bevelled edges 21 (a single beveled edge would be sufficient). In addition, the side edge of the cover 10 which is opposite the articulation 11 has two notches 22 (only one would also be sufficient). As is clearly visible in FIG. 3, when the cover 10 is closed, the bevel 21 of the plate 12 is hooked under the notch 22 of the cover 10. When pressure is exerted on the tongue 30 of the plate 12 , the beveled edge 21 disengages from the notch 22 and the cover 10 is instantly raised under the effect of the ejection force exerted by the spring 17 acting on the ball 14.

On voit sur les figures 1, 2 et 4 comment sont fixés les brins ou maillons 8 et 9 sur les lames correspondantes 2 et 4. Les moyens de fixation 6 et 7 comportent chacun un élément en L 23 bien visible sur la figure 1. L'extrémité de la partie verticale de l'élément en L 23 comporte un premier gond 25 sur lequel est articulé le brin. L'extrémité de la partie horizontale 26 de l'élément en L 23 comporte un second gond 24 sur lequel s'articule la lame 2 ou 4. Cette double articulation permet de disposer, en vitrine ou sur présentoir, le bracelet à plat, ce qui n'était pas le cas du bracelet décrit dans le document EP-A-0 319 461 déjà cité, puisque l'élément en L décrit dans ce document, présente une attache au brin qui ne peut pas pivoter. Cette présentation à plat demande peu de place en hauteur en même temps qu'elle est esthétique pour mettre le bracelet en valeur.We see in Figures 1, 2 and 4 how are fixed the strands or links 8 and 9 on the corresponding blades 2 and 4. The fixing means 6 and 7 each include an L-shaped element 23 clearly visible in Figure 1. L the end of the vertical part of the L-shaped element 23 has a first hinge 25 on which the strand is articulated. The end of the horizontal part 26 of the L-shaped element 23 has a second hinge 24 on which the blade 2 or 4 is articulated. This double articulation makes it possible to have, in the display case or on a display, the bracelet flat, this which was not the case of the bracelet described in the document EP-A-0 319 461 already cited, since the L-shaped element described in this document has an attachment to the strand which cannot pivot. This flat presentation requires little space in height at the same time as it is aesthetic to enhance the bracelet.

Les mêmes figures 1, 2 et 4 montrent enfin que la surface supérieure de la partie horizontale 26 de l'élément en L 23 se trouve située sous l'un des bords transversaux 27 ou 28 que présente le couvercle 10, ceci lorsque le fermoir est en position de fermeture. Cette disposition permet le verrouillage des lames 2 et 4. On observera pour terminer que la base 1 comporte des crans 31 et 32 dans lesquels, respectivement, l'extrémité des lames 2 et 4 viennent s'encliqueter, ce qui assure une seconde sécurité à la fermeture du fermoir, la première sécurité étant assurée par le couvercle 10.The same Figures 1, 2 and 4 finally show that the upper surface of the horizontal part 26 of the L-shaped element 23 is located under one of the transverse edges 27 or 28 that has the cover 10, this when the clasp is in the closed position. This arrangement allows the blades 2 and 4 to be locked. Finally, it will be observed that the base 1 has notches 31 and 32 in which, respectively, the end of the blades 2 and 4 snap into place, which provides a second safety to closing the clasp, the first security being provided by the cover 10.
