Definitions
- the present invention relates to a device for fine adjustment of the useful length of a bracelet, in particular a watch strap comprising two strands and a clasp for connecting the free ends of said strands to make it possible to connect these free ends with a length useful determined.
- one of the branches of the clasp is telescopic and has several openings to allow the attachment elements of the other branch to attach to different lengths of the telescopic branch.
- the CH-A-663,522 and WO-A-03/015562 both have, between the two articulated branches, a small articulated link, can be tilted in two positions, one in which its length is added to that of the branches and the other in which it is removed from that of the branches, allowing to vary the useful length of the bracelet between two determined values .
- the object of the present invention is to overcome, at least in part, the aforementioned drawbacks.
- this invention relates to a device for fine adjustment of the useful length of a bracelet, in particular a watchband, according to claim 1.
- the adjustment device object of this invention has several advantages, that of allowing a quasi-continuous adjustment over a range of several millimeters, typically over a range corresponding to half the width of the bracelet. This adjustment is made without the need to open the clasp, making it the easiest adjustment device to use that one can imagine. Thanks to this characteristic, the wearer of the bracelet realizes in real time the effect of the adjustment, which allows him to make a precise adjustment, especially since this device allows him to modify the useful length in very small increments on a adjustment range with three to four times more adjustment positions than known devices.
- this device is of extremely simple construction and can be easily dismantled and reassembled to perform a cleaning if necessary.
- the figure 1 illustrates a preferred form of the invention in which the adjustment device object of the invention is associated with a clasp with blades or articulated branches connecting the two free ends of the bracelet and generally called clasp blades or folding arms or clasp.
- This clasp of known type therefore comprises two curved branches 1, 2 hinged to one another and held in the folded position by separable hooking means (not shown).
- One of the strands 3a of the bracelet is connected by a fixing bar 4 to the free end of the branch, 1 of the clasp, while the free end of the branch 2 of this clasp is connected by a bar 5 to the adjusting device 6 object of the invention.
- This adjusting device 6 essentially comprises a first adjusting member 7 having the shape of a disc connected to the clasp 1, 2 by the bar 5, the ends of which are fixed in two parallel and diametrically opposite fastening tabs 7c, which extend perpendicularly below the disk forming the first adjustment member 7.
- This bar 5 passes through the free end of the branch 2 of the clasp located between the fixing lugs 7c of the disc 7. Consequently, the first adjustment member 7 of the adjustment device 6 is connected by the two curved branches 1, 2 of the clasp at the end of the strand 3a of the bracelet, thus ensuring a fixed position of the first adjustment member 7 relative to the longitudinal axis of the strand 3a of the bracelet.
- This first adjustment member 7 comprises a circular lateral surface 7a which serves as a guiding surface for a second manual adjustment member 8, also in the form of a disk provided with a circular rim having an inner circular guide inner surface 8f engaged with the circular guide surface 7a.
- These two circular guide surfaces 7a, 8f are held engaged by two bolts 10, as illustrated by the figure 4 allowing the inner circular guide surface 8f to rotate about the circular guide surface 7a.
- This second manual adjustment member 8 also forms a closure cover for the adjustment device 6.
- the first adjusting member 7 further comprises guide means which, in this example, are in the form of a rectilinear guide opening 7b radially oriented and parallel to the longitudinal axis of the bracelet.
- This rectilinear guide opening 7b, radially oriented is engaged with a connecting member 9 slidably mounted in this rectilinear guide opening 7b radially oriented.
- This connecting member 9 is still engaged on the one hand, with an arcuate opening 8a formed through the second manual adjustment member 8 and on the other hand, with one of the perforations 11 for fixing and the preliminary adjustment of length, arranged through the second strand 3b of the bracelet.
- the two ends of the arcuate opening 8a are located on the same diameter of the manual adjustment member 8.
- the arcuate opening 8a has the general shape of a half-ring whose center C is located near this same diameter. As illustrated by figure 4 , the outer edge of this opening 8a has a notch 8b for cooperating with the connecting member 9 for the purpose that will be explained later.
- the role of the notch 8b formed along the outer edge of the arcuate opening 8a is to allow to retain the connecting member 9 in different positions, when the member 9 is subjected to a centrifugal force relative to the manual adjustment device 8 This force can result from putting under a certain tension of the bracelet.
- a friction disc 13 is still housed between the two adjustment members 7 and 8.
- This friction disc 13 is a bent spring disk, designed to create friction between the two adjustment members 7 and 8, to prevent the second member manual adjustment 8 is able to rotate freely relative to the first.
- this friction disc 13 is traversed by the connecting member 9 and is housed in a circular recess 8c centered on the center C of the arcuate opening 8a, so that the friction disk 13 is rotated around the center C, when the second manual adjustment member 8 is rotated, thereby continuously blocking the arcuate opening 8a.
- the second adjustment member 8 "has an internal toothing 8" e engaged with a pinion 16 pivotally mounted on the first fixed adjustment member 7 and meshing with a rack 17 radially oriented and parallel to the opening straight guide 7b radially oriented and parallel to the longitudinal axis of the bracelet of the first adjustment member 7.
- the connecting member 9 is simultaneously engaged with the rectilinear guide opening 7b and with the rack 17.
- a pawl 18 is engaged with a second set of teeth 17a for positioning the adjusting device in different positions.
- the connecting member 29 is integral with an elongated slider 29a mounted in a diametrical slider 27b formed in the first adjustment member 27.
- This elongate slider 29a has a projection 29b, 29c at each of its ends.
- the second manual adjustment member 28 is guided in rotation by the circular lateral surface 27a of the first adjustment member 27 and has two driving grooves 28a, 28b intended to come respectively and alternately in engagement with the projections 29b, 29c.
- the driving grooves 28a, 28b each comprise an active portion in semicircular circular arc, the two semicircular portions of the same radius being aligned with respect to the same diameter of the second manual adjustment member 28 and staggered along of this diameter.
- This variant with two drive grooves 28a, 28b for alternately engaging two projections 29b, 29c of the slider 29a allows to double the range of adjustment, relative to the first embodiment. This adjustment range is shown by the displacement of the slider 29a, from its position illustrated by the figure 8 to that illustrated by the figure 10 and corresponds to a rotation of 360 ° of the manual adjustment member 28.
- the latter 28b has a end 28b, located beyond its semicircular active portion, to temporarily engage with the projection 29c at the moment when the projection 29b is at the intersection between the drive grooves 28a, 28b, as illustrated by FIG. figure 9 .
- the groove 28b is deeper than the groove 28a and the projection 29c is longer than the projection 29b, so that the crossover problem does not arise when the projection 29c intersects the groove 28a.
- the width of these grooves 28a, 28b increases, to allow simultaneous guiding only with one of the two grooves 28a, 28b.
- the center of the second manual adjustment member 28 comprises a circular opening in which a fixed indicator member 34 is located which has, on its internal face, a diametric slide 34a in engagement with the slide 29a.

Description
La présente invention se rapporte à un dispositif de réglage fin de la longueur utile d'un bracelet, notamment d'un bracelet de montre comportant deux brins et un fermoir de liaison des extrémités libres desdits brins pour permettre de relier ces extrémités libres avec une longueur utile déterminée.The present invention relates to a device for fine adjustment of the useful length of a bracelet, in particular a watch strap comprising two strands and a clasp for connecting the free ends of said strands to make it possible to connect these free ends with a length useful determined.
On a déjà proposé plusieurs solutions pour permettre d'apporter une modification au réglage initial de la longueur utile d'un bracelet, notamment d'un bracelet de montre. Ce genre de réglage présente un intérêt en particulier dans le cas de fermoirs connus sous le nom de fermoirs à lames ou branches déployantes, dans lesquels les extrémités du bracelet restent attachées aux extrémités libres des lames ou branches articulées l'une à l'autre du fermoir, en sorte que la longueur utile du bracelet ne peut être changée qu'en modifiant le réglage initial. Or, ce réglage nécessite l'utilisation d'outils et une certaine habileté, en sorte qu'il n'est pas à la portée de tous.Several solutions have already been proposed for making it possible to make a modification to the initial setting of the useful length of a bracelet, in particular a watchband. This kind of adjustment is of particular interest in the case of clasps known as clasps with folding blades or branches, in which the ends of the bracelet remain attached to the free ends of the blades or branches articulated to each other. clasp, so that the useful length of the bracelet can only be changed by changing the initial setting. However, this adjustment requires the use of tools and a certain skill, so that it is not within the reach of all.
Des solutions destinées à permettre de régler la longueur utile du bracelet entre deux, voire trois longueurs différentes sont décrites dans le
Dans le
Les
Ces solutions connues ne permettent de faire un réglage qu'entre deux, voire trois positions et les écarts de longueur entre ces positions sont nécessairement de quelques millimètres, la conception des dispositifs de réglage proposés ne permettant pas un réglage de longueur avec des variations quasi continues sur une plage de longueur donnée. En outre, toutes les solutions susmentionnées nécessitent l'ouverture du fermoir pour effectuer le réglage de la longueur utile du bracelet.These known solutions only make it possible to make an adjustment between two or even three positions and the length differences between these positions are necessarily of a few millimeters, the design of the proposed adjustment devices not allowing a length adjustment with almost continuous variations. on a range of given length. In addition, all the aforementioned solutions require the opening of the clasp to adjust the useful length of the bracelet.
Le but de la présente invention est de remédier, au moins en partie, aux inconvénients susmentionnés.The object of the present invention is to overcome, at least in part, the aforementioned drawbacks.
A cet effet, cette invention a pour objet un dispositif de réglage fin de la longueur utile d'un bracelet, notamment d'un bracelet de montre, selon la revendication 1.For this purpose, this invention relates to a device for fine adjustment of the useful length of a bracelet, in particular a watchband, according to claim 1.
Le dispositif de réglage objet de cette invention présente plusieurs avantages, celui de permettre un réglage quasi continu sur une plage de plusieurs millimètres, typiquement sur une plage correspondant à la moitié de la largeur du bracelet. Ce réglage s'effectue sans nécessiter l'ouverture du fermoir, ce qui en fait le dispositif de réglage le plus simple à utiliser que l'on puisse imaginer. Grâce à cette particularité, le porteur du bracelet se rend compte en temps réel de l'effet du réglage, ce qui lui permet d'effectuer un ajustage précis, surtout que ce dispositif lui permet de modifier la longueur utile par incréments très petits sur une plage de réglage comportant trois à quatre fois plus de positions de réglage que les dispositifs connus.The adjustment device object of this invention has several advantages, that of allowing a quasi-continuous adjustment over a range of several millimeters, typically over a range corresponding to half the width of the bracelet. This adjustment is made without the need to open the clasp, making it the easiest adjustment device to use that one can imagine. Thanks to this characteristic, the wearer of the bracelet realizes in real time the effect of the adjustment, which allows him to make a precise adjustment, especially since this device allows him to modify the useful length in very small increments on a adjustment range with three to four times more adjustment positions than known devices.
Enfin, ce dispositif est de construction extrêmement simple et peut être très facilement démonté et remonté pour effectuer un nettoyage en cas de besoin.Finally, this device is of extremely simple construction and can be easily dismantled and reassembled to perform a cleaning if necessary.

La
Ce fermoir de type connu comporte donc deux branches cintrées 1, 2 articulées l'une à l'autre et maintenues en position repliée par des moyens d'accrochage séparables (non représentés). Un des brins 3a du bracelet est relié par une barrette de fixation 4 à l'extrémité libre de la branche, 1 du fermoir, tandis que l'extrémité libre de la branche 2 de ce fermoir est reliée par une barrette 5 au dispositif de réglage 6 objet de l'invention.This clasp of known type therefore comprises two
Ce dispositif de réglage 6 comporte essentiellement un premier organe de réglage 7 présentant la forme d'un disque relié au fermoir 1, 2 par la barrette 5 dont les extrémités sont fixées dans deux pattes de fixation 7c parallèles et diamétralement opposées, qui s'étendent perpendiculairement sous le disque formant le premier organe de réglage 7. Cette barrette 5 traverse l'extrémité libre de la branche 2 du fermoir située entre les pattes de fixation 7c du disque 7. Par conséquent, le premier organe de réglage 7 du dispositif de réglage 6 est relié par les deux branches cintrées 1, 2 du fermoir à l'extrémité du brin 3a du bracelet, assurant ainsi une position fixe de ce premier organe de réglage 7 par rapport à l'axe longitudinal du brin 3a du bracelet. Ce premier organe de réglage 7 comporte une surface latérale circulaire 7a qui sert de surface de guidage à un second organe de réglage manuel 8, également en forme de disque muni d'un rebord circulaire présentant une surface latérale interne de guidage circulaire 8f en prise avec la surface de guidage circulaire 7a. Ces deux surfaces de guidage circulaire 7a, 8f sont maintenues engagées par deux verrous 10, comme illustré par la
Comme illustré par la
Compte tenu du fait que l'organe de liaison 9 est en prise avec l'ouverture arquée 8a du second organe de réglage manuel 8 et avec l'ouverture de guidage rectiligne 7b à orientation radiale du premier organe de réglage 7, il s'ensuit que la rotation du second organe de réglage manuel 8 entraîne celle de l'ouverture arquée 8a, qui constitue alors un élément d'entraînement de l'organe de liaison 9, en sorte que la rotation de l'ouverture arquée 8a autour de son extrémité coaxiale au centre du second organe de réglage manuel 8 se traduit par un déplacement de l'organe de liaison 9 le long de l'ouverture de guidage rectiligne 7b à orientation radiale. Etant donné, en outre, d'une part que l'ouverture radiale 7b est orientée dans le sens longitudinal du bracelet et d'autre part, que l'organe de liaison 9 est solidaire du brin de bracelet 3b, il s'ensuit que toute rotation du second organe de réglage manuel 8 se traduit, suivant le sens de cette rotation, par un allongement ou un raccourcissement de la longueur utile de ce bracelet.Given that the connecting
Le rôle du crantage 8b formé le long du bord externe de l'ouverture arquée 8a est de permettre de retenir l'organe de liaison 9 dans différentes positions, lorsque cet organe 9 est soumis à une force centrifuge par rapport au dispositif de réglage manuel 8. Cette force peut résulter de la mise sous une certaine tension du bracelet.The role of the
Un disque de friction 13 est encore logé entre les deux organes de réglage 7 et 8. Ce disque de friction 13 est un disque ressort cintré, destiné à créer une friction entre les deux organes de réglage 7 et 8, pour éviter que le second organe de réglage manuel 8 soit susceptible de tourner librement par rapport au premier. En plus, comme illustré par la
D'autres moyens de transmission de mouvement entre le second organe de réglage manuel 8 et l'organe de liaison 9, pour transformer le déplacement circulaire du second organe de réglage manuel 8 en un déplacement de l'organe de liaison 9, guidé par l'ouverture de guidage rectiligne 7b s'étendant dans le sens longitudinal du bracelet 3a, 3b, peuvent être envisagés. C'est ainsi que l'on pourrait avoir une biellette 14 dont une extrémité est articulée au second organe de réglage 8', tandis que l'autre extrémité est articulée à l'organe de liaison 9. Le positionnement angulaire du second organe de réglage 8' peut être obtenu par un cliquet 15 solidaire de premier organe de réglage 7 en prise avec une denture interne 8'd ménagée sur la face interne du rebord du second organe de réglage 8'.Other means for transmitting motion between the second
Selon une autre variante, le second organe de réglage 8" comporte une denture interne 8"e en prise avec un pignon 16 monté pivotant sur le premier organe de réglage fixe 7 et engrenant avec une crémaillère 17 à orientation radiale et parallèle à l'ouverture de guidage rectiligne 7b à orientation radiale et parallèle à l'axe longitudinal du bracelet du premier organe de réglage 7. L'organe de liaison 9 est simultanément en prise avec l'ouverture de guidage rectiligne 7b et avec la crémaillère 17. Un cliquet 18 est en prise avec une seconde denture 17a de positionnement du dispositif de réglage dans différentes positions.According to another variant, the
Dans la variante illustrée par les
Les rainures d'entraînement 28a, 28b comportent chacune une portion active en arc de cercle semi-circulaire, les deux portions semi-circulaires de même rayon, étant alignées par rapport à un même diamètre du second organe de réglage manuel 28 et décalées le long de ce diamètre. Cette variante avec deux rainures d'entraînement 28a, 28b destinées à venir alternativement en prise avec deux saillies 29b, 29c du coulisseau 29a permet de doubler la plage de réglage, par rapport à la première forme d'exécution. Cette plage de réglage est montrée par le déplacement du coulisseau 29a, de sa position illustrée par la
Comme on le voit sur la
Le centre du second organe de réglage manuel 28 comporte une ouverture circulaire dans laquelle prend place un organe indicateur fixe 34 qui comporte, sur sa face interne, une coulisse diamétrale 34a en prise avec le coulisseau 29a. La face externe de cet organe indicateur fixe 34, ainsi que la face externe du second organe de réglage manuel 28 peuvent avantageusement porter des repères (non représentés) pour permettre de connaître la position angulaire du second organe de réglage manuel 28 par rapport à la plage de réglage qui s'étend sur 360°.The center of the second
Une portion latérale interne du second organe de réglage manuel 28 porte des moyens de positionnement angulaire 28c sous la forme d'encoches régulièrement réparties autour de son axe de rotation et destinées à venir sélectivement et successivement en prise avec un pli 35a ménagé le long d'un organe de positionnement élastique 35 formé par un ressort-lame logé dans le premier organe de positionnement 27, comme illustré par la
Comme on peut le constater, si une force est exercée sur l'organe de liaison 29 suite à une traction sur le bracelet, cette force sera pratiquement dirigée vers le centre du second organe de réglage manuel 28, en sorte qu'il n'en résultera pas de couple susceptible de faire tourner involontairement ce second organe de réglage manuel 28.As can be seen, if a force is exerted on the connecting
