Abstract

The buckle for a watch strap has a female section (3) and a male section (1) and push buttons operating against a return spring (9) around a pivot (7A,B). The push buttons lock the sections by pivoting of flat release recesses (11a,b) in the buttons with respect to the male connector. The release recesses are shaped to prevent movement of the buckle sections.

Description

L'invention se rapporte à un fermoir du type de ceux qui sont utilisés dans l'horlogerie, la maroquinerie ou la joaillerie, pour permettre l'ouverture et la fermeture d'un bracelet de montre, d'un sac à main ou encore d'un collier.The invention relates to a clasp of the type used in watchmaking, leather goods or jewelry, to allow the opening and closing of a watch strap, a handbag or even 'a necklace.

Un fermoir de bracelet de montre est connu de la demande de brevet suisse CH-A-689 889. Ce fermoir comprend un bras dépliant supérieur et un bras dépliant inférieur articulés l'un à l'autre par un axe d'articulation. Chaque bras dépliant est relié à un brin du bracelet de montre. Le bras dépliant supérieur présente une fente longitudinale délimitant deux languettes pouvant s'écarter ou se rapprocher l'une par rapport à l'autre par une déformation en flexion. Le bras dépliant inférieur présente une ouverture dans laquelle le bras dépliant supérieur s'emboîte lors de la fermeture du fermoir. Le verrouillage du fermoir est assuré par deux crochets portés par les deux languettes. Les deux crochets pénètrent à l'intérieur de l'ouverture du bras dépliant inférieur en se rapprochant l'un de l'autre par la déformation en flexion des deux languettes puis s'écartent à nouveau par rappel élastique des deux languettes lorsque le bras dépliant supérieur est plaqué sur le bras dépliant inférieur. Pour déverrouiller le fermoir, on exerce une traction sur le bras dépliant supérieur par l'intermédiaire par exemple d'un brin du bracelet de montre imposant un rapprochement des deux crochets jusqu'à leur dégagement hors de l'ouverture du bras dépliant inférieur.A watch strap clasp is known from Swiss patent application CH-A-689 889. This clasp comprises an upper folding arm and a lower folding arm articulated to each other by a hinge pin. Each folding arm is connected to a strand of the watch strap. The upper folding arm has a longitudinal slot delimiting two tongues which can move apart or come closer to each other by a flexural deformation. The lower folding arm has an opening into which the upper folding arm fits when the clasp is closed. The clasp is locked by two hooks carried by the two tabs. The two hooks penetrate inside the opening of the lower folding arm while approaching one another by the flexural deformation of the two tongues then move away again by elastic return of the two tongues when the folding arm upper is pressed against the lower folding arm. To unlock the clasp, a pull is exerted on the upper folding arm by means, for example, of a strand of the watch strap imposing a bringing together of the two hooks until their release outside the opening of the lower folding arm.

Dans ce fermoir connu, on relève que le verrouillage ou le déverrouillage des deux bras dépliants met en oeuvre une même amplitude de déformation en flexion des deux languettes. Autrement dit, l'effort nécessaire pour rapprocher les deux crochets l'un de l'autre et leur permettre l'engagement dans l'ouverture du bras dépliant inférieur est le même que l'effort nécessaire pour rapprocher encore les deux crochets l'un de l'autre pour les désengager de l'ouverture. Ce type de fermoir n'apparaît pas toujours ergonomique pour les utilisateurs en ce sens que l'effort de verrouillage, égal à l'effort de déverrouillage, est ressenti comme étant trop important et conférant au fermoir une trop grande rigidité de manipulation. Il convient de noter également que l'agencement décrit dans le document précédent n'est compatible qu'avec des crochets à bords inclinés par rapport au plan représenté par l'ouverture du bras dépliant inférieur. Un décrochement plan parallèle au bras dépliant inférieur ne permettrait pas de désengager les crochets hors de l'ouverture lors du déverrouillage du fermoir.In this known clasp, it is noted that the locking or unlocking of the two folding arms implements the same amplitude of deformation in bending of the two tongues. In other words, the effort required to bring the two hooks together and allow them to engage in the opening of the lower folding arm is the same as the effort required to bring the two hooks one closer on the other to disengage them from the opening. This type of clasp does not always appear ergonomic for users in the sense that the locking force, equal to the unlocking force, is felt to be too great and giving the clasp too much rigidity in handling. It should also be noted that the arrangement described in the previous document is only compatible with hooks with edges inclined relative to the plane represented by the opening of the lower folding arm. A plan drop parallel to the lower folding arm would not allow the hooks to be disengaged from the opening when the clasp is unlocked.

Les fermoirs à poussoir pallient l'inconvénient des fermoirs à languettes flexibles en permettant de diminuer l'effort nécessaire au verrouillage tout en augmentant l'effort nécessaire au déverrouillage involontaire du fermoir. L'invention se rapporte à cette catégorie de fermoirs et plus particulièrement à un fermoir comprenant un composant femelle, un composant mâle et un poussoir mobile contre un ressort de rappel autour d'un axe de pivotement fixe par rapport au composant femelle.Push button clasps overcome the drawback of clasps with flexible tabs by reducing the effort required for locking while increasing the effort required for involuntary unlocking of the clasp. The invention relates to this category of clasps and more particularly to a clasp comprising a female component, a male component and a pusher movable against a return spring around a pivot axis fixed relative to the female component.

Un fermoir de ce type est connu des brevets américains US 4,321,734 et US 4,924,562. Le poussoir permet de verrouiller les deux composants emboîtés l'un dans l'autre par pivotement d'un décrochement plan du poussoir par rapport à un décrochement plan parallèle du composant mâle. Le décrochement plan du poussoir s'étend parallèlement à l'axe de pivotement. La résistance à l'effort nécessaire pour déverrouiller le fermoir est ainsi transmise par le poussoir à l'axe de pivotement. Par ailleurs, l'effort nécessaire à la fermeture du poussoir est imposé par la raideur du ressort de rappel élastique contre lequel le poussoir pivote autour de l'axe de pivotement lors de l'emboîtement du composant mâle dans le composant femelle. En choisissant un axe de pivotement plus solide et une raideur du ressort de rappel moins élevée, on diminue l'effort nécessaire à la fermeture du fermoir et on augmente la résistance à l'effort nécessaire à une ouverture involontaire du fermoir. De surcroît, des rampes d'introduction ménagées sur le composant mâle ou sur le poussoir facilitent l'emboîtement des deux composants l'un dans l'autre.A clasp of this type is known from US patents US 4,321,734 and US 4,924,562. The pusher makes it possible to lock the two components nested one inside the other by pivoting a plan recess of the pusher relative to a parallel plan recess of the male component. The plan recess of the pusher extends parallel to the pivot axis. The resistance to the effort necessary to unlock the clasp is thus transmitted by the pusher to the pivot axis. Furthermore, the force required to close the pusher is imposed by the stiffness of the elastic return spring against which the pusher pivots about the pivot axis when the male component fits into the female component. By choosing a more solid pivot axis and a lower stiffness of the return spring, the effort required to close the clasp is reduced and the resistance to the effort required for involuntary opening of the clasp is increased. In addition, introduction ramps formed on the male component or on the pusher facilitate the fitting of the two components into one another.

Dans ces fermoirs connus, on relève que c'est l'axe de pivotement qui supporte et détermine la résistance à l'effort nécessaire au déverrouillage du fermoir. Cette conception se révèle défavorable dans la mesure où elle impose à l'axe de pivotement, au poussoir et au composant femelle des dimensions en diamètre de l'axe et en épaisseur des alésages qui alourdissent le fermoir et le rendent plus encombrant.In these known clasps, it is noted that it is the pivot axis which supports and determines the resistance to the force necessary for unlocking the clasp. This design turns out to be unfavorable insofar as it imposes on the pivot axis, on the pusher and on the female component dimensions in diameter of the axis and in thickness of the bores which weigh down the clasp and make it more bulky.

L'un des buts de l'invention est de remédier à l'inconvénient relevé ci-dessus dans les fermoirs à poussoir pivotant.One of the aims of the invention is to remedy the drawback noted above in the pivoting push-button clasps.

A cet effet, l'invention a pour objet un fermoir comprenant un composant femelle, un composant mâle et un poussoir mobile contre un ressort de rappel autour d'un axe de pivotement fixe par rapport au composant femelle pour verrouiller les deux composants par pivotement d'un décrochement plan du poussoir par rapport au composant mâle, caractérisé en ce que le décrochement plan du poussoir est orienté perpendiculairement à l'axe de pivotement pour bloquer les deux composants en déplacement parallèlement à l'axe de pivotement et en ce qu'un ergot solidaire du composant femelle coopère avec une encoche solidaire du composant mâle pour bloquer les deux composants en déplacement perpendiculairement à l'axe de pivotement.To this end, the subject of the invention is a clasp comprising a female component, a male component and a push-piece movable against a return spring around a pivot axis fixed relative to the female component to lock the two components by pivoting d '' a plan recess of the pusher relative to the male component, characterized in that the plan recess of the pusher is oriented perpendicular to the pivot axis to block the two components in movement parallel to the pivot axis and in that a lug secured to the female component cooperates with a notch secured to the male component to block the two components in movement perpendicular to the pivot axis.

Lorsque les deux composants sont emboîtés l'un dans l'autre, le décrochement plan du poussoir orienté perpendiculairement à l'axe de pivotement permet de les bloquer en déplacement parallèlement à cet axe mais n'offre pas de résistance à un effort tendant à déplacer les deux composants perpendiculairement à cet axe de pivotement. La résistance à un tel effort est assurée par l'ergot solidaire du composant femelle coopérant avec l'encoche solidaire du composant mâle. Par cet agencement, l'effort nécessaire pour ouvrir le fermoir involontairement est supporté par les composants eux-mêmes sans solliciter l'axe de pivotement du poussoir. Il en résulte la possibilité de diminuer, à résistance de déverrouillage égale, les dimensions de l'axe de pivotement et du poussoir pour réduire l'encombrement et le poids d'ensemble du fermoir. De surcroît, la protection de l'axe de pivotement par rapport à la résistance à un effort de déverrouillage involontaire confère une meilleure fiabilité et une meilleure longévité au fermoir.When the two components are nested one inside the other, the flat detachment of the pusher oriented perpendicular to the pivot axis makes it possible to block them in movement parallel to this axis but does not offer resistance to a force tending to move the two components perpendicular to this pivot axis. Resistance to such a force is ensured by the lug secured to the female component cooperating with the notch secured to the male component. By this arrangement, the effort required to open the clasp involuntarily is supported by the components themselves without stressing the pivot axis of the pusher. This results in the possibility of reducing, with equal unlocking resistance, the dimensions of the pivot axis and of the plunger to reduce the overall size and weight of the clasp. In addition, the protection of the pivot axis with respect to the resistance to an involuntary unlocking force confers better reliability and better longevity to the clasp.

D'autres avantages de l'invention apparaîtront à la lecture de la description de deux modes de réalisation illustrés par les dessins.Other advantages of the invention will appear on reading the description of two embodiments illustrated by the drawings.

La figure 1 est une vue éclatée d'un premier mode d'exécution d'un fermoir selon l'invention.Figure 1 is an exploded view of a first embodiment of a clasp according to the invention.

La figure 2 est une vue en coupe du fermoir de la figure 1 lorsque les composants mâle et femelle du fermoir sont emboîtés l'un dans l'autre, les poussoirs étant en position de déverrouillage.Figure 2 is a sectional view of the clasp of Figure 1 when the male and female components of the clasp are fitted into one another, the pushers being in the unlocked position.

La figure 3 est une vue de face parallèlement aux axes de pivotement des poussoirs montrant la position relative des poussoirs et du composant mâle lorsque le fermoir est dans une position verrouillée.Figure 3 is a front view parallel to the pivot axes of the pushers showing the relative position of the pushers and the male component when the clasp is in a locked position.

La figure 4 est une vue de face parallèlement aux axes de pivotement des poussoirs montrant la position relative des poussoirs et du composant mâle lorsque le fermoir est dans une position déverrouillée.Figure 4 is a front view parallel to the pivot axes of the pushers showing the relative position of the pushers and the male component when the clasp is in an unlocked position.

La figure 5 est une vue en perspective d'un deuxième mode d'exécution d'un fermoir selon l'invention.Figure 5 is a perspective view of a second embodiment of a clasp according to the invention.

La figure 6 est une vue en coupe du fermoir de la figure 5 lorsque les composants mâle et femelle sont emboîtés l'un dans l'autre, les poussoirs étant en position de déverrouillage.Figure 6 is a sectional view of the clasp of Figure 5 when the male and female components are fitted one into the other, the pushers being in the unlocked position.

Les figures 7, 8 et 9 sont des vues en perspective de trois variantes du deuxième mode d'exécution d'un fermoir selon l'invention.Figures 7, 8 and 9 are perspective views of three variants of the second embodiment of a clasp according to the invention.

Un fermoir comprend, en référence à la figure 1, un composant mâle 1 et un composant femelle 3. Les composants 1 et 3 sont destinés à être reliés par exemple aux deux brins d'un bracelet de montre. Un poussoir gauche 5A et un poussoir droit 5B sont montés mobiles autour d'un axe de pivotement 7A, 7B fixes par rapport au composant femelle 3. Les poussoirs 5A et 5B sont mobiles contre un ressort de rappel 9, mieux visible sur la figure 2.A clasp comprises, with reference to FIG. 1, a male component 1 and a female component 3. The components 1 and 3 are intended to be connected for example to the two strands of a watch strap. A left pusher 5A and a right pusher 5B are mounted movable around a pivot axis 7A, 7B fixed relative to the female component 3. The pusher 5A and 5B are movable against a return spring 9, better visible in FIG. 2 .

Selon l'invention, chaque poussoir 5A, 5B est muni d'un décrochement plan 11A, 11B orienté perpendiculairement à l'axe de pivotement du poussoir 7A, 7B pour verrouiller les deux composants 1 et 3 par pivotement des décrochements plans 11A et 11B par rapport au composant mâle 1. Comme visible sur la figure 3, dans la position verrouillée, chaque décrochement plan 11A, 11B des poussoirs pivotants bloque les deux composants 1, 3 en déplacement parallèlement aux axes de pivotement 7A, 7B suivant le sens représenté par la flèche F. Un ergot gauche 13A et un ergot droit 13B solidaires du composant femelle coopèrent avec respectivement une encoche gauche 15A et une encoche droite 15B solidaires du composant mâle 1 pour bloquer les deux composants 1 et 3 en déplacement perpendiculairement aux axes de pivotement 7A et 7B. Comme visible sur la figure 4, dans la position déverrouillée, les décrochements plans 11A et 11B ont pivoté avec les poussoirs 5A et 5B pour se désengager du composant mâle 1. Le déblocage des deux composants 1 et 3 en déplacement parallèlement aux axes de pivotement 7A, 7B suivant le sens de la flèche F permet de désengager les encoches 15A, 15B solidaires du composant mâle 1 des ergots 13A, 13B solidaires du composant femelle 3 et d'ouvrir ainsi le fermoir en déplaçant les deux composants perpendiculairement aux axes de pivotement 7A, 7B.According to the invention, each pusher 5A, 5B is provided with a planar recess 11A, 11B oriented perpendicular to the pivot axis of the pusher 7A, 7B to lock the two components 1 and 3 by pivoting the planar recesses 11A and 11B by relative to the male component 1. As can be seen in FIG. 3, in the locked position, each planar recess 11A, 11B of the pivoting pushers blocks the two components 1, 3 in movement parallel to the pivot axes 7A, 7B in the direction represented by the arrow F. A left lug 13A and a right lug 13B secured to the female component cooperate with a left notch 15A and a right notch 15B respectively secured to the male component 1 to block the two components 1 and 3 in movement perpendicular to the pivot axes 7A and 7B. As visible in FIG. 4, in the unlocked position, the planar recesses 11A and 11B have pivoted with the pushers 5A and 5B to disengage from the male component 1. The unlocking of the two components 1 and 3 in displacement parallel to the pivot axes 7A, 7B in the direction of the arrow F makes it possible to disengage the notches 15A, 15B integral with the component male 1 of the pins 13A, 13B integral with the female component 3 and thus open the clasp by moving the two components perpendicular to the pivot axes 7A, 7B.

Pour emboîter ou désemboîter les deux composants 1 et 3, le composant mâle 1 est placé en position inférieure par rapport au composant femelle 3. Les deux composants mâle et femelle sont ensuite réunis par un déplacement parallèlement aux axes de pivotement 7A, 7B des poussoirs dans le sens opposé à celui représenté par la flèche F sur les figures 3 et 4. Ces figures montrent également des rampes d'entrée 19A, 19B du composant mâle 1 coopérant avec des rampes d'entrée 21A, 21B des poussoirs 5A, 5B pour faciliter l'emboîtement du composant mâle 1 dans le composant femelle 3.To nest or disengage the two components 1 and 3, the male component 1 is placed in the lower position relative to the female component 3. The two male and female components are then joined together by a displacement parallel to the pivot axes 7A, 7B of the pushers in the opposite direction to that represented by the arrow F in FIGS. 3 and 4. These figures also show entry ramps 19A, 19B of the male component 1 cooperating with entry ramps 21A, 21B of the pushers 5A, 5B to facilitate the fitting of the male component 1 into the female component 3.

Un deuxième mode d'exécution de l'invention, illustré par les figures 5 et 6, ne se distingue du mode d'exécution précédent qu'en ce que les composants femelle et mâle 3 et 1 sont respectivement montés sur un bras dépliant supérieur 23 et sur un bras dépliant inférieur 21 articulés l'un à l'autre par un axe d'articulation 25. Ce dernier permet de bloquer les deux composants 1 et 3 en déplacement perpendiculairement aux axes de pivotement 7A et 7B des poussoirs 5A et 5B, en remplacement des ergots 13A et 13B solidaires du composant femelle 3 et des encoches 15A, 15B solidaires du composant mâle. Le remplacement des ergots et des encoches par l'axe d'articulation 25 des bras dépliants inférieur 21 et supérieur 23 est bien visible sur la figure 6.A second embodiment of the invention, illustrated by FIGS. 5 and 6, differs from the previous embodiment only in that the female and male components 3 and 1 are respectively mounted on an upper folding arm 23 and on a lower folding arm 21 articulated to each other by a hinge pin 25. The latter makes it possible to block the two components 1 and 3 in movement perpendicular to the pivot axes 7A and 7B of the pushers 5A and 5B, replacing the pins 13A and 13B secured to the female component 3 and the notches 15A, 15B secured to the male component. The replacement of the lugs and notches by the articulation axis 25 of the lower 21 and upper 23 folding arms is clearly visible in FIG. 6.

Par référence à la figure 5, les composants femelle 3 et mâle 1 pivotent par rapport au bras dépliant supérieur 23 et au bras dépliant inférieur 21 respectivement autour d'axes de pivotement 33 et 31.With reference to FIG. 5, the female 3 and male 1 components pivot relative to the upper folding arm 23 and to the lower folding arm 21 respectively around pivot axes 33 and 31.

Les figures 7, 8 et 9 sont des vues en perspective de trois variantes du deuxième mode d'exécution d'un fermoir selon l'invention. Par référence à la figure 7, le composant femelle 3 pivote par rapport au bras dépliant supérieur 23 autour d'un axe de pivotement 33 et le composant mâle 1 est fixe par rapport au bras dépliant inférieur 21. Par référence à la figure 8, les deux composants femelle et mâle 3 et 1 sont fixes respectivement au bras dépliant supérieur 23 et au bras dépliant inférieur 21. Par référence à la figure 9, les deux composants femelle et mâle 3 et 1 sont incorporés respectivement aux bras dépliant supérieur 23 et inférieur 21.Figures 7, 8 and 9 are perspective views of three variants of the second embodiment of a clasp according to the invention. With reference to FIG. 7, the female component 3 pivots relative to the upper folding arm 23 around a pivot axis 33 and the male component 1 is fixed relative to the lower folding arm 21. With reference to FIG. 8, the two female components and male 3 and 1 are fixed respectively to the upper folding arm 23 and to the lower folding arm 21. With reference to FIG. 9, the two female and male components 3 and 1 are incorporated respectively in the upper folding arm 23 and lower 21.

Dans les modes d'exécution décrits précédemment, d'une part le composant femelle est muni de deux poussoirs gauche et droit ainsi que de deux ergots gauche et droit. De même, le composant mâle est muni de deux encoches droite et gauche. Le doublement par symétrie des poussoirs, ergots, et encoches confère une plus grande sécurité de verrouillage au fermoir. Cependant, le verrouillage peut encore être obtenu avec un poussoir unique et un ergot coopérant avec une encoche uniques. D'autre part, comme visible sur les figures 3 et 4, le décrochement plan de chaque poussoir, lors du verrouillage ou du déverrouillage du fermoir, pivote par rapport à un décrochement plan parallèle respectivement gauche 17A et droit 17B du composant mâle 1. Là encore, l'engagement ou le désengagement des décrochements plans des poussoirs par rapport au décrochement plan parallèle du composant mâle augmente la sécurité de verrouillage du fermoir. Mais on peut concevoir un fermoir selon l'invention dans lequel les décrochements plans des poussoirs pivotent par rapport à une surface plane confondue avec la base même du composant mâle.In the embodiments described above, on the one hand the female component is provided with two left and right pushers as well as two left and right pins. Likewise, the male component is provided with two right and left notches. The symmetrical doubling of the pushers, lugs, and notches gives greater locking security to the clasp. However, the locking can still be obtained with a single pusher and a lug cooperating with a single notch. On the other hand, as can be seen in FIGS. 3 and 4, the plan recess of each pusher, when the clasp is locked or unlocked, pivots with respect to a respectively planar parallel recess 17A and right 17B of the male component 1. There still, the engagement or disengagement of the planar recesses of the pushers relative to the parallel plan recess of the male component increases the locking security of the clasp. However, it is possible to design a clasp according to the invention in which the planar recesses of the pushers pivot relative to a plane surface merged with the very base of the male component.

Le ressort de rappel 9 est parfaitement protégé et caché par le composant femelle dans lequel il est logé. Il peut être dédoublé et remplacé par un plot élastomère ou un ressort de torsion monté autour des axes de pivotement des poussoirs. Ces derniers peuvent être solidaires des poussoirs eux-mêmes, du composant femelle ou être constitués par des vis.The return spring 9 is perfectly protected and hidden by the female component in which it is housed. It can be split and replaced by an elastomer stud or a torsion spring mounted around the pivot axes of the pushers. The latter may be integral with the pushers themselves, with the female component or be constituted by screws.

Il convient de noter que les composants mâle et femelle, les poussoirs, ainsi que les bras dépliants se prêtent avantageusement à une fabrication pour un procédé de moulage par injection de métal, dit procédé MIM.It should be noted that the male and female components, the pushers, as well as the folding arms are advantageously suitable for manufacture for a metal injection molding process, known as the MIM process.
