A locking device for a bracelet, comprising a base (11, 21, 41), at least one foldable section (1, 3; 23), a locking cover (12, 24, 42) adapted to be depressed by a lateral slewing motion with respect to the longitudinal direction of the bracelet straps, and means (13, 14; 32, 35; 43, 44) for keeping the cover depressed on the base, characterized in that the locking cover (12, 24, 42) is hinged to the base (11, 24, 41) and that at least one of the straps (4, 26) is hinged to the free end of a folding section (1, 23) by an articulation (6, 34) which, when the folding section (1, 23) is folded, bears on the base (11, 21, 41) of the locking device by a portion (7, 31) the thickness of which is smaller than that of the folding section, said portion (7, 31) being held on the base (11, 21, 41) by the pressure of the depressed cover (12, 24, 42) which is locked to the base (11, 21, 41) by said means (13, 14; 32, 35; 43, 44).

Description

La présente invention concerne un fermoir de bracelet comprenant au moins un dépliant. Il est connu que les fermoirs de bracelet à dépliants n'offrent pas toute la sécurité désirable contre une ouverture intempestive du fermoir, par exemple lorsque lors d'un mouvement du bras, le bracelet s'accroche quelque part.The present invention relates to a bracelet clasp comprising at least one leaflet. It is known that foldable bracelet clasps do not offer all the desirable security against inadvertent opening of the clasp, for example when during a movement of the arm, the bracelet hangs somewhere.

En conséquence, le but de la présente invention est de réaliser un fermoir de bracelet comprenant au moins un dépliant, offrant une grande sécurité contre une ouver­ture intempestive lors du porté du bracelet. En outre, le fermoir doit pouvoir être utilisé pour des brace­lets métalliques ou en cuir et, au moins dans certaines formes d'exécution, permettre une exécution extra-plate du bracelet. Pour atteindre ce but, le fermoir selon l'invention est réalisé comme décrit dans la partie caractérisante de la revendication 1. La revendication 3 décrit une forme d'exécution pour un bracelet métallique à dépliant triple, la revendication 5 une forme d'exécu­tion pour un bracelet cuir et la revendication 7 une troisième forme d'exécution du fermoir.Consequently, the object of the present invention is to produce a bracelet clasp comprising at least one leaflet, offering great security against inadvertent opening when the bracelet is worn. In addition, the clasp must be able to be used for metallic or leather bracelets and, at least in certain embodiments, allow an extra-flat execution of the bracelet. To achieve this object, the clasp according to the invention is produced as described in the characterizing part of claim 1. Claim 3 describes an embodiment for a metallic bracelet with triple leaflet, claim 5 an embodiment for a leather strap and claim 7 a third embodiment of the clasp.

En position fermée du couvercle, lorsque les dépliants sont rabattus sur la base, ce couvercle rabattu latéra­lement immobilise soit une partie terminale mince des extrémités des brins du bracelet métallique, soit des moyens prévus à une face latérale d'une boucle recevant un des brins du bracelet en cuir de la seconde forme d'exécution, en appuyant fortement ces parties, resp. ces moyens contre la base. Ceci donne une très grande sécurité contre toute ouverture intempestive du fermoir. Par le fait que dans la première forme d'exécution, le couvercle fermé n'emprisonne pas les brins métalliques ni les dépliants du bracelet entre lui et la base, mais seulement une partie terminale mince de ces brins, la hauteur du fermoir en condition fermée est moins du double de l'épaisseur des brins du bracelet, ce qui permet une exécution extra-plate du fermoir utilisé pour un bracelet à dépliant triple.In the closed position of the cover, when the leaflets are folded down on the base, this laterally folded cover immobilizes either a thin end portion of the ends of the strands of the metal bracelet, or means provided on a lateral face of a loop receiving one of the strands of the leather strap of the second embodiment, by strongly pressing these parts, resp. these means against the base. This gives great security against any untimely opening of the clasp. By the fact that in the first embodiment, the closed cover does not trap the metallic strands or the leaflets of the bracelet between it and the base, but only a thin terminal part of these strands, the height of the clasp in closed condition is less than twice the thickness of the strands of the bracelet, which allows an extra-flat execution of the clasp used for a bracelet with triple leaflet.

La figure 1 montre une première forme d'exécution du fermoir selon l'invention. Ce fermoir est prévu pour verrouiller un bracelet métallique à dépliants triples 1, 2 et 3, les extrémités libres des dépliants 1 et 3 étant articulées aux derniers maillons 4 et 5 des brins du bracelet. Comme indiqué en figure 1, l'articulation des dépliants 1 et 3 aux brins du bracelet est réalisée par un axe supporté entre les branches 8 d'une pièce en forme d'escalier 6 articulée elle-même à l'extrémi­té du dernier maillon 4 ou 5 des brins du bracelet. La pièce 6 comporte une partie mince 7 à la face infé­rieure de laquelle sont fixées les branches 8 supportant l'axe d'articulation. La longueur de la partie mince 7, mesurée dans la direction de l'axe d'articulation, est plus grande que la distance entre les faces extérieures des branches 8, de sorte que les extrémités 7′ de la partie mince 7 dépassent vers l'extérieur, resp. vers la gauche et vers la droite par rapport aux branches 8 entre lesquelles le dépliant est articulé.Figure 1 shows a first embodiment of the clasp according to the invention. This clasp is designed to lock a metal bracelet with triple leaflets 1, 2 and 3, the free ends of the leaflets 1 and 3 being articulated to the last links 4 and 5 of the strands of the bracelet. As indicated in FIG. 1, the articulation of the leaflets 1 and 3 to the strands of the bracelet is produced by an axis supported between the branches 8 of a stair-shaped part 6 articulated itself at the end of the last link 4 or 5 of the bracelet strands. The part 6 has a thin part 7 on the underside of which are fixed the arms 8 supporting the hinge pin. The length of the thin part 7, measured in the direction of the axis of articulation, is greater than the distance between the external faces of the branches 8, so that the ends 7 ′ of the thin part 7 project towards the outside, resp. to the left and to the right with respect to the branches 8 between which the leaflet is articulated.

Lorsque le dépliant 1 et/ou 3 est rabattu sur la partie centrale 2, il s'engage dans l'ouverture 9 entre les branches 2′ de la partie 2 et les branches latérales 8 s'engagent dans un logement 10 en forme de T de la base 11 du fermoir. Dans cette condition rabattue des dé­pliants, et comme indiqué en figure 3, les extrémités 7′ de la partie mince viennent s'appuyer sur la base 11, de part et d'autre des extrémités latérales de l'ouverture 10 ce qui empêche les dépliants de pivoter plus avant. Pour verrouiller le bracelet dans la condition fermée décrite ci-dessus, il suffit alors de rabattre le couvercle 12 sur la base 11 à laquelle il est articulé. On remarque que, par rapport à la direction longitudi­nale des brins du bracelet, le couvercle 12 se rabat latéralement sur la base 11. En condition rabattue du couvercle 12, l'extrémité repliée 13 de celui-ci s'enga­ge à cran (voir fig.3) avec l'extrémité 14 de la base 11. Une telle fixation est extrêmement sûre par le fait que les dépliants 1 et 3 sont fermement appuyés et tenus contre la base 11 par les parties minces 7, elles-mêmes fortement appuyées contre cette base par le couvercle 12 rabattu et fermé à cran. Le couple "d'arrachage" C indiqué en fig.2, cherchant à écarter les dépliants rabattus est extrêmement élevé, ce qui empêche toute ouverture intempestive du bracelet par traction sur les brins de celui-ci. Il est visible que le couvercle fermé n'emprisonne aucun brin ni maillon du bracelet, mais seulement les parties minces 7 de la pièce 6, de sorte que la hauteur du fermoir en condi­tion fermée est inférieure au double de l'épaisseur de chaque brin, ce qui permet une exécution extra-plate.When the leaflet 1 and / or 3 is folded over the central part 2, it engages in the opening 9 between the branches 2 ′ of the part 2 and the lateral branches 8 engage in a T-shaped housing 10 from the base 11 of the clasp. In this folded-down condition of the leaflets, and as indicated in FIG. 3, the ends 7 ′ of the thin part come to rest on the base 11, on either side of the lateral ends of the opening 10 which prevents the leaflets to rotate further. To lock the bracelet in the closed condition described above, it then suffices to close the cover 12 on the base 11 to which it is articulated. It is noted that, relative to the longitudinal direction of the strands of the bracelet, the cover 12 folds laterally on the base 11. In the folded down condition of the cover 12, the folded end 13 of the latter engages with notch (see fig. .3) with the end 14 of the base 11. Such a fixing is extremely safe in that the leaflets 1 and 3 are firmly pressed and held against the base 11 by the thin parts 7, themselves strongly pressed against this base by cover 12 folded down and closed with notches. The "pull-out" torque C indicated in fig.2, seeking to spread the folded leaflets is extremely high, which prevents any untimely opening of the bracelet by pulling on the strands thereof. It is visible that the closed cover does not trap any strand or link of the bracelet, but only the thin parts 7 of the piece 6, so that the height of the clasp in closed condition is less than twice the thickness of each strand, which allows an extra-flat execution.

Les figures 4 à 6 montrent un deuxième exemple d'exécu­tion dans lequel le fermoir permet de verrouiller les brins d'un bracelet cuir. La figure 4 montre un brin 20 d'un bracelet en cuir articulé à la base 21 du fermoir, cette base comportant deux branches 22 à l'extrémité desquelles est articulé un dépliant 23. Le fermoir comprend aussi un couvercle 24 articulé à un côté de la base 21, de sorte que par rapport à la direction longitudinale des brins du bracelet, le couvercle se rabat latéralement sur la base. La figure 4 montre une boucle 25 prévue pour recevoir le second brin en cuir 26 du bracelet. La boucle 25 comporte une base 27 porteuse d'un téton 28 s'engageant dans une des ouvertures 29 du second brin pour mettre celui-ci de longueur en condi­tion portée du bracelet. La figure 6 montre que la base 27 de la boucle 25 est liée à l'extrémité libre du dépliant 23 par une articulation 34. Lorsque le second brin 26 est introduit dans la boucle 25 comme illustré en figures 5 et 6 et qu'il est tenu par le téton 28 dans cette boucle, le bracelet peut être verrouillé en rabattant le dépliant 23 sur les branches 22 de la base 21, ce dépliant 23 s'engageant entre les branches 22 de la base 21 et l'articulation de longueur plus grande que la largeur du dépliant s'engageant dans une ouverture 35 de la base 21. En position rabattue du dépliant, les extrémités latérales de la boucle 25 viennent se placer à côté de la paroi 30 (fig.1) de la base 21, dans l'épaisseur de cette dernière. Comme indiqué en figure 4, la boucle comporte une languette 31 montée sur la face latérale tournée vers le fermoir de l'articulation 34. En position rabattue du dépliant 23, cette languette dépassante vient s'appliquer sur la base 21, à côté de l'ouverture 35. En position verrouillée, le couvercle 24 est rabattu sur la base 21 et son extrémité 32 s'engage à cran avec l'extrémité 33 de la base. Le couvercle rabattu appuie fortement sur la languette 31 et la maintient fermement contre la base, ce qui empêche toute ouverture intempestive du bracelet en condition portée.Figures 4 to 6 show a second embodiment in which the clasp allows the strands of a leather strap to be locked. FIG. 4 shows a strand 20 of a leather bracelet articulated at the base 21 of the clasp, this base comprising two branches 22 at the end of which a leaflet 23 is articulated. The clasp also comprises a cover 24 articulated on one side of the base 21, so that with respect to the longitudinal direction of the strands of the bracelet, the cover folds laterally on the base. FIG. 4 shows a loop 25 provided for receiving the second leather strand 26 of the bracelet. The loop 25 comprises a base 27 carrying a stud 28 engaging in one of the openings 29 of the second strand to put the latter in the worn condition of the bracelet. Figure 6 shows that the base 27 of the loop 25 is linked to the free end of the leaflet 23 by a hinge 34. When the second strand 26 is introduced into the loop 25 as illustrated in FIGS. 5 and 6 and that it is held by the stud 28 in this loop, the bracelet can be locked by folding the leaflet 23 over the branches 22 of the base 21, this leaflet 23 engaging between the branches 22 of the base 21 and the articulation of length greater than the width of the leaflet engaging in an opening 35 of the base 21. In the folded position of the leaflet, the lateral ends of the loop 25 are placed next to the wall 30 (fig.1) of the base 21, in the thickness of the latter. As shown in Figure 4, the loop has a tongue 31 mounted on the side face facing the clasp of the joint 34. In the folded position of the leaflet 23, this protruding tongue is applied to the base 21, next to the opening 35. In the locked position, the cover 24 is folded down on the base 21 and its end 32 engages with notch with the end 33 of the base. The folded cover presses strongly on the tongue 31 and keeps it firmly against the base, which prevents any untimely opening of the bracelet in worn condition.

Les figures 7 à 10 montrent une troisième forme d'exé­cution du fermoir selon l'invention. Dans les formes d'exécution selon figures 1 et 4, le couvercle 12, resp. 24 se ferme à cran (13,14;32,33) sur la base (11,21) du fermoir. Cette solution, facile à réaliser en fabrica­tion, a cependant l'inconvénient qu'après quelques milliers de manipulations, le crochement à cran se fatigue en raison de l'usure due au frottement métal contre métal. La forme d'exécution selon figures 7 à 10 ne présente pas ce défaut.Figures 7 to 10 show a third embodiment of the clasp according to the invention. In the embodiments according to Figures 1 and 4, the cover 12, resp. 24 closes with notch (13,14; 32,33) on the base (11,21) of the clasp. This solution, which is easy to carry out in manufacturing, has the drawback, however, that after a few thousand manipulations, the notched hooking becomes tired due to wear due to metal against metal friction. The embodiment according to Figures 7 to 10 does not have this defect.

La figure 7 montre la base 41 à laquelle est articulé le couvercle 42. Un poussoir 43 est monté de manière coulissante dans la base 41, du côté opposé à celui de l'articulation du couvercle 42 muni d'un dégagement 44 dans sa partie repliée 45. Les figures 7, 8 et 10 montrent que le poussoir 43 a une forme en U avec une partie supérieure 46 et une partie inférieure 47. La partie inférieure comporte de chaque côté un rabatte­ment 48 qui s'engage dans une rainure 49 de la base 41, ce qui maintient le poussoir en place. La rainure 49 est plus large que les rabattements 48, ce qui permet un déplacement latéral du poussoir dans les deux directions indiquées par la flèche F en figure 7. A l'état de repos, un ressort 50 agit sur le poussoir de manière à obliger celui-ci à se maintenir dans la position la plus extérieure. Lors du rabattement du couvercle 42 sur la base 41, les extrémités 51 de la partie repliée viennent se placer en face des bords latéraux 52 du poussoir et, en appuyant sur ce dernier, contre la force du ressort 50, les extrémités 51 passent devant les bords 52 et permettent au couvercle de se rabattre entièrement sur la base 41. Ceci montre que le couvercle est rabattu sur la base sans fermeture à cran, c'est-à-dire sans frottement. Il agit comme un pène de serrure pour verrouiller le couvercle à la base. En relachant le poussoir, les bords 52 viennent s'engager sous l'action de la force de pression du ressort 50, dans des dégage­ments 53 à la face intérieure des extrémités 51 de la partie pliée 45. Le couvercle est ainsi maintenu dans sa position rabattue sur la base. Il est visible que la troisième forme d'exécution ne présente pas les défauts dûs à l'usure des parties de la fermeture à cran, mais que la fermeture se fait sans frottement grace à la présence du poussoir 43 et de son ressort de rappel 50.FIG. 7 shows the base 41 to which the cover 42 is hinged. A pusher 43 is slidably mounted in the base 41, on the side opposite that of the articulation of the cover 42 provided with a clearance 44 in its folded part 45. FIGS. 7, 8 and 10 show that the pusher 43 has a U shape with an upper part 46 and a lower part 47. The lower part comprises on each side a folding 48 which engages in a groove 49 of the base 41, which keeps the pusher in place. The groove 49 is wider than the folds 48, which allows lateral movement of the pusher in the two directions indicated by the arrow F in FIG. 7. In the rest state, a spring 50 acts on the pusher so as to force the latter to maintain itself in the outermost position. When the cover 42 is folded down on the base 41, the ends 51 of the folded part come to face the lateral edges 52 of the pusher and, by pressing on the latter, against the force of the spring 50, the ends 51 pass in front of the edges 52 and allow the cover to be folded down entirely on the base 41. This shows that the cover is folded down on the base without notch closure, that is to say without friction. It acts as a lock bolt to lock the cover at the base. By releasing the pusher, the edges 52 engage under the action of the pressure force of the spring 50, in clearances 53 at the inner face of the ends 51 of the folded part 45. The cover is thus held in its position folded down on the base. It is visible that the third embodiment does not have the defects due to the wear of the parts of the notch closure, but that the closure is done without friction thanks to the presence of the pusher 43 and its return spring 50 .

Ce qui précède montre que le fermoir selon l'invention peut être utilisé pour plusieurs types de bracelets métalliques ou en cuir et que l'invention n'est pas limitée aux formes d'exécution décrites.The above shows that the clasp according to the invention can be used for several types of metal or leather bracelets and that the invention is not limited to the embodiments described.
