L'invention concerne un maillon réglable 1 pour bracelet 10.The invention relates to an adjustable link 1 for a bracelet 10.

L'invention concerne le domaine des fixations réglables, en particulier pour les objets destinés à être portés sur le corps humain ou animal. Il concerne en particulier les fixations de bracelets, colliers, ceintures, sangles, baudriers et similaires, utilisés en particulier dans les domaines de la bijouterie, de la joaillerie, de la maroquinerie, ou encore dans la sellerie.The invention relates to the field of adjustable fasteners, in particular for objects intended to be worn on the human or animal body. It relates in particular to the fastenings of bracelets, necklaces, belts, straps, shoulder belts and the like, used in particular in the fields of jewelery, jewelery, leather goods, or in the upholstery.

Ces objets différents par leurs dimensions ou leur forme de détail, mais similaires dans leur fonctionnalité, seront ci-après dénommés sous le vocable unique de « bracelet ».These objects, different in size or detail, but similar in functionality, will hereinafter be referred to as "bracelet".

Ce maillon réglable 1 comporte, tel que visible sur la figure 2, au moins un premier demi-maillon 2 et au moins un deuxième demi-maillon 3, qui sont agencés pour être assemblés mobiles l'un par rapport à l'autre selon une direction de mobilité D, par la coopération de moyens de guidage 21 et de moyens de guidage complémentaire 31.This adjustable link 1 comprises, as visible on the figure 2 at least one first half-link 2 and at least one second half-link 3, which are arranged to be assembled movably relative to each other in a direction of mobility D, by the cooperation of guide means 21 and complementary guiding means 31.

L'invention est décrite ici avec le cas simplifié et non limitatif de deux demi-maillons complémentaires mobiles l'un par rapport à l'autre, et il est naturellement possible de réaliser un maillon réglable selon l'invention comportant davantage d'éléments mobiles entre eux.The invention is described here with the simplified and nonlimiting case of two complementary half-links movable relative to each other, and it is naturally possible to make an adjustable link according to the invention comprising more moving elements. between them.

Cette direction de mobilité D peut être linéaire, tel que représenté sur les figures 1 à 10, ou encore curviligne, tel que visible sur la figure 12, ce qui peut présenter un intérêt dans le cas de bracelets à petit rayon de courbure, notamment pour des bracelets pour dame ou pour enfant.This direction of mobility D can be linear, as represented on the Figures 1 to 10 , or curvilinear, as visible on the figure 12 which may be of interest in the case of bracelets with a small radius of curvature, in particular for bracelets for ladies or for children.

Ce premier demi-maillon 2 et ce deuxième demi-maillon 3 sont, encore, assemblés de façon à constituer un ensemble imperdable, par la coopération de moyens d'arrêt 22 et de moyens d'arrêt complémentaire 32.This first half-link 2 and this second half-link 3 are, again, assembled so as to constitute a captive assembly, by the cooperation of stop means 22 and complementary stop means 32.

Selon l'invention, le premier demi-maillon 2 comporte au moins un doigt 23 s'étendant selon la direction D, et qui comporte des moyens de verrouillage 24 à rappel élastique sensiblement radial par rapport à la direction D. Ces moyens de verrouillage 24 sont mobiles entre une position repliée et une position déployée.According to the invention, the first half-link 2 comprises at least one finger 23 extending in the direction D, and which comprises locking means 24 with substantially radial resilient return relative to the direction D. These locking means 24 are movable between a folded position and an extended position.

Le deuxième demi-maillon 3 comporte, de façon complémentaire, au moins un canal 33 s'étendant selon la direction D, et qui est agencé pour permettre le passage de ce doigt 23, dans une seule de ces positions, repliée ou déployée, des moyens de verrouillage 24 du doigt 23 correspondant à ce canal 33. Naturellement, il y a au moins autant de canaux 33 dans le deuxième demi-maillon 3 que de doigts 23 sur le premier demi-maillon 2.The second half-link 3 comprises, in a complementary manner, at least one channel 33 extending in the direction D, and which is arranged to allow the passage of this finger 23, in only one of these positions, folded or deployed, locking means 24 of the finger 23 corresponding to this channel 33. Naturally, there are at least as many channels 33 in the second half-link 3 as fingers 23 on the first half-link 2.

Le deuxième demi-maillon 3 comporte encore, au voisinage de chaque canal 33, des moyens de verrouillage complémentaire 34, qui sont agencés pour coopérer dans au moins une position de verrouillage avec les moyens de verrouillage 24 du doigt 23 correspondant au canal 33 concerné, dans l'autre des positions, déployée ou repliée, de ces moyens de verrouillage 24.The second half-link 3 further includes, in the vicinity of each channel 33, complementary locking means 34, which are arranged to cooperate in at least one locking position with the locking means 24 of the finger 23 corresponding to the channel 33 concerned, in the other of the positions, deployed or folded, of these locking means 24.

Tel que représenté sur les figures 5 et 8, dans une réalisation économique, le doigt 23 comporte une tête de diamètre supérieur à celui du canal 33, à l'extrémité d'un corps de diamètre inférieur ou égal à celui du canal 33, cette tête est fendue, la fente lui conférant son élasticité. Le corps peut également être fendu, tel que visible sur les figures. Les moyens de verrouillage 24 comportent un cône d'introduction dans au moins un sens, et de préférence dans les deux sens de mouvement du doigt 23. Les moyens de verrouillage complémentaire 34 comportent au moins une gorge avec une rampe d'entrée de conicité voisine de celle de la tête du doigt 23.As shown on the Figures 5 and 8 in an economic embodiment, the finger 23 has a head of diameter greater than that of the channel 33, at the end of a body of diameter less than or equal to that of the channel 33, the head is split, the slot conferring its elasticity. The body can also be split as shown in the figures. The locking means 24 comprise an insertion cone in at least one direction, and preferably in both directions of movement of the finger 23. The complementary locking means 34 comprise at least one groove with an adjacent conical entry ramp from that of the head of the finger 23.

Ces rampes ou cônes d'introduction permettent la manoeuvre du maillon réglable 1 sans effort excessif, pour passer de l'une à l'autre de ses positions de verrouillage.These ramps or introduction cones allow the operation of the adjustable link 1 without excessive effort, to move from one to the other of its locking positions.

Dans une variante de l'invention, qui n'est pas détaillée ici car accessible à tout mécanicien, et dont le fonctionnement est similaire mais inversé, les moyens de rappel élastique ne sont pas situés au niveau du doigt 23, qui est alors rigide, mais du canal 33.In a variant of the invention, which is not detailed here because accessible to any mechanic, and whose operation is similar but inverted, the elastic return means are not located at the finger 23, which is then rigid, but of the channel 33.

Les moyens de verrouillage 24 et les moyens de verrouillage complémentaire 34 définissent ensemble au moins deux positions de verrouillage discrètes et distantes selon la direction D. La figure 15 illustre une variante avec une pluralité de positions de verrouillage. Cette pluralité de positions est représentée au niveau des moyens de verrouillage complémentaire 34, et on comprend qu'il est tout aussi possible de réaliser le doigt 23 avec une pluralité d'éléments mobiles radialement, ou même de combiner les deux configurations.The locking means 24 and the complementary locking means 34 together define at least two positions of discreet and remote locks in the D direction. figure 15 illustrates a variant with a plurality of locking positions. This plurality of positions is represented at the level of the complementary locking means 34, and it is understood that it is equally possible to make the finger 23 with a plurality of radially movable elements, or even to combine the two configurations.

Dans une variante avantageuse de réalisation, tel que visible sur la figure 14, le doigt 23 comporte une gorge, dans laquelle est mont un joint « o-ring » ou similaire, de forme sensiblement torique, ce joint constituant les moyens de verrouillage 24. Cette réalisation est particulièrement économique, et autorise une miniaturisation qui est intéressante pour des bracelets de très petite taille. La figure 14 illustre le cas où le deuxième demi-maillon 3 comporte plusieurs moyens de verrouillage complémentaire 34, en nombre supérieur à deux, constitués chacun dans cet exemple par une gorge de réception du joint torique.In an advantageous embodiment variant, as visible on the figure 14 , the finger 23 has a groove, in which is mounted an o-ring seal or the like, of substantially toric shape, this seal constituting the locking means 24. This embodiment is particularly economical, and allows a miniaturization which is interesting for very small bracelets. The figure 14 illustrates the case where the second half-link 3 comprises several additional locking means 34, in number greater than two, each constituted in this example by a receiving groove of the O-ring.

De façon préférée et tel que visible sur les figures, le premier demi-maillon 2 et le deuxième demi-maillon 3 comportent respectivement les moyens d'arrêt 22 et les moyens d'arrêt complémentaire 32, selon la direction D, pour leur montage imperdable l'un par rapport à l'autre, et pour définir une course maximale de réglage entre d'une part une première position rapprochée où une première face d'appui 25 du premier demi-maillon 2 est en contact avec une deuxième face d'appui 35 du deuxième demi-maillon 3, et d'autre part une deuxième position éloignée où les moyens d'arrêt 22 sont en contact avec les moyens d'arrêt complémentaire 32.In a preferred manner and as visible in the figures, the first half-link 2 and the second half-link 3 respectively comprise the stop means 22 and the complementary stop means 32, in the direction D, for their captive mounting. relative to each other, and to define a maximum adjustment stroke between on the one hand a first close position where a first bearing face 25 of the first half-link 2 is in contact with a second face of support 35 of the second half-link 3, and secondly a second remote position where the stop means 22 are in contact with the complementary stop means 32.

La configuration illustrée est avantageuse quand on souhaite un montage borgne, tel que visible sur la figure 9, il est facile d'équiper le premier demi-maillon 2 du doigt 3, puis d'enfiler dans les alésages faisant fonction de moyens de guidage 21 les goujons filetés faisant office de moyens de guidage complémentaires 31, que l'on visse dans le deuxième demi-maillon3. Ces goujons se terminent par des collerettes constituant les moyens d'arrêt complémentaires, et le montage imperdable est ainsi très facilement réalisé.The illustrated configuration is advantageous when one wishes a blind assembly, as visible on the figure 9 , it is easy to equip the first half-link 2 of the finger 3, then to thread into the bores acting as guide means 21 the threaded studs acting as complementary guide means 31, which is screwed into the second half-link3. These studs end with flanges constituting the complementary stop means, and the captive mounting is thus very easily achieved.

Pour passer de l'une des positions de verrouillage à l'autre, il convient d'appliquer un effort, selon la direction D, sur l'un des demi-maillons par rapport à l'autre, soit en traction pour passer de la position de la figure 8 à celle de la figure 5, soit en compression dans le cas contraire. Pour transformer cet effort selon la direction D en un effort à composante radiale d'intensité suffisante pour vaincre l'effort résistant des moyens de verrouillage 24, un profil particulier est aménagé sur l'un ou/et l'autre des demi-maillons 2 et 3. Ainsi, de façon préférée, les moyens de verrouillage 24 ou/et les moyens de verrouillage complémentaire 34 comportent au moins une rampe autorisant, sous l'action d'un effort appliqué selon la direction D sur le premier 2 ou/et deuxième 3 demi-maillon, et lors du mouvement relatif entre le premier 2 et le deuxième 3 demi-maillon, le passage des moyens de verrouillage 24 de leur position repliée à leur position déployée ou inversement.To move from one of the locking positions to another, it is appropriate to apply a force, in the direction D, on one of the half-links with respect to the other, or in tension to move from the position of the figure 8 to that of the figure 5 or in compression in the opposite case. To transform this force in the direction D into a radial component force of sufficient intensity to overcome the resisting force of the locking means 24, a particular profile is arranged on one or the other of the half-links 2 and 3. Thus, preferably, the locking means 24 and / or the complementary locking means 34 comprise at least one ramp allowing, under the action of a force applied in the direction D on the first 2 and / or second half-link, and during the relative movement between the first 2 and the second 3 half-link, the passage of the locking means 24 from their folded position to their deployed position or vice versa.

Cette rampe peut être conique comme dans la réalisation des figures 5 et 8, ou encore en calotte sphérique tel que visible sur la figure 14, ou similaire.This ramp can be conical as in the realization of Figures 5 and 8 , or in spherical cap as visible on the figure 14 , or similar.

Dans une réalisation avantageuse, tel que visible sur les figures, les moyens de guidage 21 sont limités à une extrémité par les moyens d'arrêt 22, et les moyens de guidage complémentaire 31 sont limités à une extrémité par les moyens d'arrêt complémentaire 32.In an advantageous embodiment, as visible in the figures, the guide means 21 are limited at one end by the stop means 22, and the complementary guide means 31 are limited at one end by the complementary stop means 32 .

Dans une réalisation particulière, tel que visible sur les figures, le doigt 23 et le canal 33 sont distincts respectivement des moyens de guidage 21 et des moyens de guidage complémentaire 31.In a particular embodiment, as visible in the figures, the finger 23 and the channel 33 are separate respectively from the guide means 21 and the complementary guide means 31.

De préférence, tel que visible sur les figures, le doigt 23 est agencé au voisinage d'une première face d'appui 25 du premier demi-maillon 2, et est ajustable en longueur par rapport à ce dernier, par exemple par la coopération d'un filetage et d'un taraudage. Un tel réglage en longueur peut, encore, occuper des positions discrètes, par exemple si le doigt 23 fileté comporte une collerette avec un ou plusieurs trous de goupilles chacun indexable par goupillage avec un ou plusieurs trous que comporte le premier demi-maillon 2 taraudé.Preferably, as shown in the figures, the finger 23 is arranged in the vicinity of a first bearing surface 25 of the first half-link 2, and is adjustable in length relative to the latter, for example by the cooperation of a thread and a tapping. Such a length adjustment can still occupy discrete positions, for example if the finger 23 Thread comprises a flange with one or more pin holes each indexable by pinning with one or more holes that includes the first half-link 2 threaded.

Dans une réalisation préférée, d'une grande solidité et de coût modéré, les moyens de guidage 21, respectivement les moyens de guidage complémentaire 31, sont constitués par un alésage complémentaire à un doigt constituant les moyens de guidage complémentaire 31, respectivement les moyens de guidage 21, le doigt étant ajustable en longueur par rapport au demi-maillon qui le porte. Cet ajustement en longueur peut être réalisé de façon similaire à celle décrite ci-dessus pour le doigt 23. Les figures illustrent une réalisation préférée où les moyens d'arrêt 22, respectivement les moyens d'arrêt complémentaire 32, sont constitués par une collerette s'étendant radialement au-delà de ce doigt, cette collerette circulant dans un chambrage coaxial aux moyens de guidage 21, respectivement respectivement les moyens de guidage complémentaire 31, ce chambrage comportant une extrémité avec un lamage d'appui de cette collerette, ce lamage constituant les moyens d'arrêt complémentaire 32, respectivement lesdits moyens d'arrêt 22.In a preferred embodiment, of great strength and moderate cost, the guide means 21, respectively the complementary guide means 31, are constituted by a bore complementary to a finger constituting the complementary guide means 31, respectively the means of guide 21, the finger being adjustable in length relative to the half-link that carries it. This length adjustment can be made in a manner similar to that described above for the finger 23. The figures illustrate a preferred embodiment where the stop means 22, or the complementary stop means 32, are constituted by a collar. extending radially beyond this finger, this flange circulating in a recess coaxial with the guide means 21, respectively respectively the complementary guide means 31, this recess having an end with a counter bearing of this flange, this countersink constituting the complementary stop means 32, respectively said stop means 22.

Sur l'exemple de réalisation des figures, les moyens de guidage 21 et les moyens de guidage complémentaire 31 associés sont doublés, et s'étendent selon des directions parallèles entre elles, de façon à prévenir tout gauchissement du maillon réglable 1 pendant sa manoeuvre d'ajustement, ou encore en service. Dans une variante non illustrée par les figures, les moyens de guidage 21 et les moyens de guidage complémentaire 31 associés comportent au moins un méplat ou similaire de façon à garantir le parallélisme de mouvement entre les surfaces orthogonales à la direction D du premier demi-maillon 2 et du demi-maillon 3 au cours de leur écartement ou de leur rapprochement, que la direction D soit linéaire ou curviligne.In the exemplary embodiment of the figures, the guide means 21 and the associated complementary guide means 31 are doubled, and extend in directions parallel to each other, so as to prevent any warping of the adjustable link 1 during its operation. adjustment, or in service. In a variant not illustrated by the figures, the guide means 21 and the complementary guide means 31 associated comprise at least one flat or similar so as to ensure the parallelism of movement between the orthogonal surfaces to the direction D of the first half-link 2 and the half-link 3 during their spacing or their approximation, that the direction D is linear or curvilinear.

Ce type de montage permet, tel que visible sur les figures et notamment sur la figure 9, un montage extrêmement facile des demi-maillons entre eux.This type of assembly allows, as visible in the figures and in particular on the figure 9 , an extremely easy assembly of the half-links between them.

De façon avantageuse, le premier demi-maillon 2 et le deuxième demi-maillon 3 comportent respectivement une première chambre 26 et une deuxième chambre 36, qui sont agencées pour, quand le premier demi-maillon 2 et le deuxième demi-maillon 3 sont assemblés l'un à l'autre, définir une chambre unique 4. Le maillon réglable 1 comporte alors au moins un élément de masquage 5 agencé pour être monté prisonnier dans la chambre unique 4 entre le premier demi-maillon 2 et le deuxième demi-maillon 3, et pour cacher, au moins du côté d'une face supérieure 6 de ce maillon réglable 1 assemblé, l'ensemble du mécanisme de réglage et de sécurité constitué par les moyens de guidage 21, les moyens de guidage complémentaire 31, les moyens d'arrêt 22, les moyens d'arrêt complémentaire 32, le doigt 23, les moyens de verrouillage 24, le canal 33, et les moyens de verrouillage complémentaire 34. Cet élément de masquage 5 a, de préférence, un profil complémentaire à celui de la chambre 4.Advantageously, the first half-link 2 and the second half-link 3 respectively comprise a first chamber 26 and a second chamber 36, which are arranged for, when the first half-link 2 and the second half-link 3 are assembled. one to the other, define a single room 4. The adjustable link 1 then comprises at least one masking element 5 arranged to be mounted prisoner in the single chamber 4 between the first half-link 2 and the second half-link 3, and to hide, at least on the side of an upper face 6 of this adjustable link 1 assembled, the assembly of the adjustment and safety mechanism constituted by the guide means 21, the complementary guide means 31, the means stop 22, the complementary stop means 32, the finger 23, the locking means 24, the channel 33, and the complementary locking means 34. This masking element 5 preferably has a profile complementary to thatfrom bedroom 4.

De façon préférée, cet élément de masquage 5 est encore agencé pour cacher, par des flasques 51, sur deux faces latérales 7 ; 8 adjacentes à la face supérieure 6 du maillon réglable1 de part et d'autre de celle-ci selon la direction D, l'ensemble du mécanisme de réglage et de sécurité constitué par les moyens de guidage 21, les moyens de guidage complémentaire 31, les moyens d'arrêt 22, les moyens d'arrêt complémentaire 32, le doigt 23, les moyens de verrouillage 24, le canal 33, et les moyens de verrouillage complémentaire 34.Preferably, this masking element 5 is further arranged to hide, by flanges 51, on two lateral faces 7; 8 adjacent to the upper face 6 of the adjustable link1 on either side thereof in the direction D, the assembly of the adjustment and safety mechanism constituted by the guide means 21, the complementary guide means 31, the stop means 22, the complementary stop means 32, the finger 23, the locking means 24, the channel 33, and the complementary locking means 34.

Pour assurer le placage de l'élément de masquage 5 contre les parois intérieures des demi-maillons 2 et 3 à proximité de la face supérieure 6, avantageusement l'élément de masquage 5 comporte une surface d'appui 54 agencée pour coopérer avec au moins une surface d'appui complémentaire 29 que comporte au moins un des demi-maillons 2 ou 3, pour, à la façon d'une came, à maintenir l'élément de masquage 5 en appui sur les extrémités de la première chambre 26 et une deuxième chambre 36 situées à proximité de la face supérieure 6 du maillon réglable 1. Dans une exécution simple, l'une des surfaces d'appui 54 ou d'appui complémentaire 29 est pentée par rapport à l'autre, de façon à créer un mouvement transversal ad hoc de l'élément de masquage 5 lors de la fermeture ou de l'ouverture du maillon réglable 1.To ensure the plating of the masking element 5 against the inner walls of the half-links 2 and 3 near the upper face 6, advantageously the masking element 5 comprises a bearing surface 54 arranged to cooperate with at least a complementary bearing surface 29 that comprises at least one of the half-links 2 or 3, for, in the manner of a cam, to maintain the masking element 5 bearing on the ends of the first chamber 26 and a second chamber 36 located near the upper face 6 of the adjustable link 1. In a simple embodiment, one of the bearing surfaces 54 or additional support 29 is slanted relative to the other, so as to create an ad hoc transverse movement of the masking element 5 when closing or opening the adjustable link 1.

Dans un exemple de réalisation illustré par les figures 16 et 17, la surface d'appui 54 de l'élément de masquage est un tourillon 39, porté par deux rampes 37 et 38 solidaires respectivement du premier demi-maillon 2 et du deuxième demi-maillon 3, disposées en croix, de façon éloigner ou rapprocher ce tourillon 39 transversalement, de façon sensiblement orthogonale à la direction D, lors du rapprochement ou de l'écartement des demi-maillons.In an exemplary embodiment illustrated by the Figures 16 and 17 , the bearing surface 54 of the masking element is a trunnion 39, carried by two ramps 37 and 38 secured respectively to the first half-link 2 and the second half-link 3, arranged in a cross, so as to move away or closer this trunnion 39 transversely, substantially orthogonal to the direction D, during the approximation or spacing of the half-links.

Dans une variante, les flasques 51 comportent chacun une vis 53, constituant une surface d'appui 54, dont l'extrémité est logée dans une gorge latérale, constituant une surface d'appui complémentaire 29, que comporte un des demi-maillons, par exemple le deuxième demi-maillon 3, pour ajuster la distance de l'élément de masquage 5 à la face supérieure 6 : cette distance peut être constante si cette gorge latérale est parallèle à la direction D, elle peut être variable, tel que visible dans le changement de position illustré par les figures 5 et 8, quand la gorge latérale est conçue pour plaquer l'élément de masquage 5 aux extrémités de la première chambre 26 et une deuxième chambre 36 situées à proximité de la face supérieure 6 du maillon réglable 1.In a variant, the flanges 51 each comprise a screw 53, constituting a bearing surface 54, the end of which is housed in a lateral groove, constituting a complementary bearing surface 29, which comprises one of the half-links, for example example the second half-link 3, to adjust the distance of the masking element 5 to the upper face 6: this distance can be constant if this lateral groove is parallel to the direction D, it can be variable, as visible in the change of position illustrated by the Figures 5 and 8 , when the lateral groove is designed to press the masking element 5 at the ends of the first chamber 26 and a second chamber 36 located near the upper face 6 of the adjustable link 1.
