Description
Fermoir à boucle dépliante pour bracelet Clasp with folding buckle for bracelet
La présente invention concerne un fermoir à boucle dépliante pour bracelet comprenant au moins deux lames articulées entre elles et présentant deux extrémités libres munies de moyens pour attacher les extrémités du bracelet et un dispositif de verrouillage et déverrouillage du fermoir en position repliée et superposée des extrémités libres . The present invention relates to a folding buckle clasp for bracelet comprising at least two blades articulated together and having two free ends provided with means for attaching the ends of the bracelet and a locking device and unlocking the clasp in the folded position and superimposed free ends .
Les fermoirs à boucles dépliantes à deux ou plusieurs lames articulées entre elles et munies à leurs extrémités libres de moyens pour attacher les extrémités du bracelet sont connus . Par bracelet on entend aussi bien un bracelet de montre qu'un bracelet bijou. Ce type de fermoir une fois monté sur le bracelet forme une boucle que le fermoir soit ouvert ou fermé. Un intérêt de ces fermoirs est le fait qu'en cas ouverture intempestive du fermoir le bracelet ne peut pas tomber car il doit passer par-dessus le poignet de l'utilisateur qui en principe se rend compte que le fermoir s'est ouvert. En position fermée du fermoir les lames articulées sont repliés les unes contre des autres et un mécanisme assure le verrouillage du fermoir à cette position repliée. The clasps with folding buckles with two or more blades hinged together and provided at their free ends with means for attaching the ends of the bracelet are known. By bracelet we mean both a watch bracelet and a jewel bracelet. This type of clasp once mounted on the bracelet forms a loop that the clasp is open or closed. An interest of these clasps is the fact that in case of inadvertent opening of the clasp the bracelet can not fall because it must pass over the wrist of the user who in principle realizes that the clasp has opened. In the closed position of the clasp articulated blades are folded against each other and a mechanism ensures the locking of the clasp in this folded position.
La présente invention propose une nouvelle solution simple à réaliser.
Le fermoir selon la présente invention est caractérisé par le fait qu'une des extrémités du fermoir est munie sur la surface de superposition d'une plaquette présentant deux projections s 'étendant au delà de ladite surface de superposition et fixée par deux chevilles latéralement espacées sur la dite surface de superposition engagés dans deux trous de guidage oblongs de la surface de superposition, que ladite plaquette est faite d'un matériau rigide et déformable élast iquement et elle présente entre les deux chevilles une partie avec des découpes, que la seconde extrémité du fermoir est munie de protubérances destinées à collaborer avec ladite plaquette lorsque les deux extrémités sont superposées pour obtenir grâce à la déformation élastique de la plaquette le verrouillage du fermoir et le déverrouillage lorsque les deux extrémités de ladite plaquette sont poussées l'une contre l'autre. The present invention proposes a new simple solution to achieve. The clasp according to the present invention is characterized in that one end of the clasp is provided on the superposition surface of a wafer having two projections extending beyond said superposition surface and fixed by two pins laterally spaced on said superimposed surface engaged in two oblong guide holes of the superimposing surface, that said plate is made of a rigid and elastically deformable material and has between the two pins a portion with cutouts, that the second end of clasp is provided with protuberances intended to collaborate with said wafer when the two ends are superimposed to obtain, thanks to the elastic deformation of the wafer, the locking of the clasp and the unlocking when the two ends of said wafer are pushed against each other .
Les découpes effectuées dans la plaquette permettent de la rendre déformable élastiquement transversalement et les trous oblongues de guider le déplacement des parties engagées de la plaquette pour s'éloigner des protubérances et soit obtenir le verrouillage soit le déverrouillage. Accessoirement, les découpes peuvent être faites de sorte à correspondre au
logo d'un horloger ou bijoutier voire aux initiales du propriétaire. The cuts made in the wafer make it elastically deformable transversely and the oblong holes guide the displacement of the engaged parts of the wafer to move away from the protuberances and to obtain the locking or unlocking. Incidentally, the cutouts can be made to match the logo of a watchmaker or jeweler or even the initials of the owner.
L'invention sera décrite plus en détail à l'aide du dessin annexé The invention will be described in more detail with the aid of the attached drawing.
Les figures 1 et 2 sont des vues recto et verso en perspective d'un fermoir avec deux lames en position déployée ; Figures 1 and 2 are front and back views in perspective of a clasp with two blades in the deployed position;
La figure la est une vue agrandie d'un détail; Figure la is an enlarged view of a detail;
Les figure 3 et 4 sont des vues recto et verso en perspective d'un fermoir avec deux lames en position déployée selon une variante; Figures 3 and 4 are front and back views in perspective of a clasp with two blades in the deployed position according to a variant;
La figure 3a est une vue agrandie d'un détail ; Figure 3a is an enlarged view of a detail;
Nous avons représenté aux figures 1 et 2 un fermoir comprenant deux lames cintrées 1, 2 articulées par une charnière 3. En position fermée la lame 2 est rabattue de gauche à droite (figure 2) sur la lame 1 Les extrémités libres 4 et 5 de deux lames 2 et 1 sont munies de moyens pour y attacher les extrémités d'un bracelet. L'extrémité 5 de la lame 1 est munie sur sa face de superposition d'une plaquette 6 fait d'un matériau rigide et déformable élastiquement . La plaquette 6 présente deux projections latérales 61 et elle est fixée sur la lame 1 par deux chevilles 8 telles
que vis, rivets etc. Les chevilles 8 sont engagées dans deux trous oblongs 9 percés dans la lame l.La partie de la plaquette 6 située entre les chevilles 8 présente une partie 62 avec des découpes destinées à créer une sorte de ressort dans le plan de la plaquette. En plaçant le pouce et l'index sur les deux projections 61 pour appliquer deux efforts antagonistes on arrive à déformer élastiquement la partie de la plaquette 62 avec les découpes par compression. La déformation est limitée par la grandeur des trous oblongs 9 dans lesquels les chevilles 8 peuvent se déplacer. Dans le cas de la figure 1 les trous oblongs 9 convergent vers l'extrémité 5 de la lame ce qui provoque lors de la compression un déplacement des extrémités 61 aussi vers l'extrémité 5. Lorsque l'on relâche les efforts appliqués par les deux doigts la plaquette revient à sa position de repos. L'extrémité 4 de la lame 2 est munie de deux protubérances 7 (figure la) . Lorsque on rabat la lame 2 sur la lame 1 les protubérances 7 viennent se frotter conte les extrémités transversales intérieures de deux projections 61. En appliquant l'extrémité 4 contre l'extrémité 5 et en poussant, les protubérances 7 poussent les projections 61 vers l'extrémité 5. Les chevilles 8 se déplacent dans les trous oblongs 9 vers l'extrémité 5 et la partie de la plaquette avec les découpes se comprime. Lorsque les protubérances passent sous les projections 61,
elles reviennent à leur position initiale sous la poussée de rappel de la partie 62. Ce qui assure le verrouillage du fermoir. Pour le déverrouiller, il suffit de pousser entre le pouce et l'index les deux projections 61 l'une contre l'autre comme expliqué précédemment pour obtenir la libération des protubérances 7. We have shown in Figures 1 and 2 a clasp comprising two curved blades 1, 2 hinged by a hinge 3. In the closed position the blade 2 is folded from left to right (Figure 2) on the blade 1 The free ends 4 and 5 of two blades 2 and 1 are provided with means for attaching the ends of a bracelet. The end 5 of the blade 1 is provided on its superposition face with a plate 6 made of a rigid and elastically deformable material. The plate 6 has two lateral projections 61 and is fixed on the blade 1 by two pins 8 such that screws, rivets etc. The pins 8 are engaged in two oblong holes 9 drilled in the blade 1. The portion of the wafer 6 located between the pins 8 has a portion 62 with cutouts for creating a kind of spring in the plane of the wafer. By placing the thumb and forefinger on the two projections 61 to apply two opposing forces one can elastically deform the portion of the wafer 62 with the compression cuts. The deformation is limited by the size of the oblong holes 9 in which the pins 8 can move. In the case of Figure 1 the oblong holes 9 converge towards the end 5 of the blade which causes during compression a displacement of the ends 61 also towards the end 5. When releasing the forces applied by the two fingers the pad returns to its rest position. The end 4 of the blade 2 is provided with two protuberances 7 (Figure la). When the blade 2 is folded onto the blade 1, the protuberances 7 are rubbed against the inner transverse ends of two projections 61. By applying the end 4 against the end 5 and pushing, the protuberances 7 push the projections 61 towards the end. end 5. The pegs 8 move in the oblong holes 9 towards the end 5 and the portion of the wafer with the cuts compresses. When the protuberances pass under projections 61, they return to their initial position under the restoring thrust of the part 62. This ensures the locking of the clasp. To unlock it, simply push between the thumb and forefinger the two projections 61 against each other as explained above to obtain the release of the protuberances 7.
Le fermoir présenté aux figures 3 à 4 est quasiment identique à celui des figures 1 à 2 et nous avons référencé les éléments identiques par les numéros utilisés pour les figures 1 et 2 suivis d'un zéro. The clasp shown in Figures 3 to 4 is almost identical to that of Figures 1 to 2 and we referenced the identical elements by the numbers used for Figures 1 and 2 followed by a zero.
Il y a deux différences entre les deux exécutions. La première différence est la disposition et forme des protubérances 70 sur l'extrémité 40 de la lame 20 et la disposition de deux trous oblongs 90 sur la lame 10. Les protubérances 70 sont positionnées de sorte qu'elles ne viennent pas se frotter contre les projections 610 mais les flancs latéraux 601 de la plaquette 60. Dans ce cas pour obtenir le verrouillage et le déverrouillage du fermoir il faut que les chevilles se déplacent transversalement donc l'une contre l'autre. Pour cette raison les trous oblongs 90 sont orientes l'un contre l'autre. There are two differences between the two executions. The first difference is the arrangement and forms the protuberances 70 on the end 40 of the blade 20 and the arrangement of two oblong holes 90 on the blade 10. The protuberances 70 are positioned so that they do not come rub against them. projections 610 but the lateral flanks 601 of the wafer 60. In this case to obtain the locking and unlocking of the clasp must the dowels move transversely so against each other. For this reason the oblong holes 90 are oriented against each other.
Aussi bien les lames que la plaquette peuvent être faites en métal noble ou pas voire en plastique .
Si l'on fait un fermoir à trois lames, les deux extérieures se rabattant contre celle du milieu le même dispositif peut être utilisé.
Both the blades and the wafer can be made of noble metal or not even plastic. If you make a clasp with three blades, the two outer folds against the middle one the same device can be used.
