Description

La présente invention concerne les articles de chevelure dans lesquels un premier mors est articulé à un second mors par des moyens d'articulation comportant un ressort de rappel.The present invention relates to hair articles in which a first jaw is articulated to a second jaw by articulation means comprising a return spring.

On connaít notamment des articles de chevelure en forme de pince utilisés pour la coiffure féminine. De telles pinces sont connues depuis longtemps, et décrites notamment dans les documents FR-A-770 805, FR-A-755 662 ou US-A-2 201 719.We especially know of hair-shaped articles pliers used for female hairstyle. Such pliers are known for a long time, and described in particular in documents FR-A-770 805, FR-A-755 662 or US-A-2 201 719.

Les pinces à cheveux connues comprennent généralement un premier mors et un second mors, articulés l'un à l'autre par des moyens d'articulation autorisant leur pivotement respectif autour d'un axe d'articulation entre une position écartée et une position rapprochée. Des moyens élastiques sollicitent en pivotement le premier et le second mors l'un par rapport à l'autre vers leur position rapprochée. Les moyens d'articulation comprennent, sur le premier mors, deux premiers ergots perforés parallèles espacés l'un de l'autre selon un écartement de stabilisation, et, sur le second mors, deux ergots perforés parallèles espacés l'un de l'autre selon un écartement approprié pour s'engager de part et d'autre des premiers ergots perforés. Un arbre de liaison, orienté selon l'axe d'articulation, traverse les quatre ergots perforés pour relier les mors.Known hair clips generally include a first bit and a second bit, articulated to each other by articulation means allowing their respective pivoting around an axis of articulation between a spaced position and a position close together. Elastic means pivotally urge the first and second bit relative to each other towards their close position. The means of articulation include, on the first jaw, two first parallel perforated lugs spaced one on the other according to a stabilization gap, and, on the second bit, two parallel perforated pins spaced apart from each other according to an appropriate spacing to engage on either side of the first perforated lugs. A connecting shaft, oriented along the axis of articulation, crosses the four perforated lugs to connect the bit.

Dans ces pinces à cheveux connues, les moyens élastiques comprennent un ressort en fil métallique élastiquement flexible enroulé en hélice autour de l'axe d'articulation. Une première extrémité du fil élastiquement flexible dépasse radialement à l'écart de l'axe et vient en appui sur la face interne du premier mors. La seconde extrémité du fil élastiquement flexible se prolonge radialement à l'écart de l'axe et vient en appui contre le second mors. Le ressort est précontraint en rotation autour de l'axe, de façon que ses deux extrémités dépassantes sollicitent les mors vers leur position rapprochée.In these known hair clips, the elastic means include an elastically flexible wire spring wound in a helix around the axis of articulation. A first end of the elastically flexible wire protrudes radially at away from the axis and comes to bear on the internal face of the first bit. The second end of the elastically flexible wire is extends radially away from the axis and bears against the second bit. The spring is prestressed in rotation around the axis, so that its two projecting ends stress the bit towards their close position.

Un premier inconvénient de cette structure connue résulte de l'utilisation particulière des articles de chevelure qui, lorsqu'ils sont positionnés dans une coiffure, laissent généralement apparente leur partie postérieure, qui est précisément la partie constituée par la zone d'articulation et par le fil métallique élastiquement flexible enroulé en hélice. Il en résulte un effet particulièrement inesthétique, car la structure de ressort en fil métallique élastiquement flexible est clairement apparente et donne un aspect d'organe mécanique à un article de chevelure qui devrait en principe constituer un objet de parure et d'ornement.A first drawback of this known structure results the particular use of hair items which, when positioned in a hairstyle, leave generally visible their posterior part, which is precisely the part formed by the articulation zone and by the wire elastically flexible metal wound in a helix. The result a particularly unsightly effect, because the spring structure made of elastically flexible wire is clearly visible and gives a mechanical organ appearance to a hair article which should in principle be an object of adornment and ornament.

Un autre inconvénient très important de cette structure connue résulte de la difficulté de montage du ressort précontraint. Il faut en effet assembler en une seule fois les quatre pièces formées par les deux mors, par le ressort et par l'arbre de liaison, en appliquant sur le ressort une force appropriée pour vaincre la précontrainte exercée par ses extrémités radialement dépassantes.Another very important drawback of this structure known results from the difficulty of mounting the prestressed spring. It is indeed necessary to assemble in one go the four parts formed by the two jaws, by the spring and by the shaft connection, applying an appropriate force to the spring to overcome the prestress exerted by its ends radially protruding.

Dans le document EP-A-0 901 759, on a proposé de cacher le ressort hélicoïdal derrière une paroi rapportée sur l'un des mors. Cette solution ne résout pas le problème de la difficulté de montage du ressort précontraint, et elle tend au contraire à accentuer cette difficulté en limitant l'accès à la zone occupée par le ressort.In document EP-A-0 901 759, it has been proposed to hide the helical spring behind a wall attached to one of the jaws. This solution does not solve the problem of the difficulty of mounting of the pre-stressed spring, and on the contrary it tends to accentuate this difficulty by limiting access to the occupied area by the spring.

Dans le document EP-A-0 847 710, on a proposé d'incorporer le ressort hélicoïdal de rappel dans un boítier rapporté entre les premiers ergots perforés. Le boítier est réalisé par assemblage d'un corps principal de boítier à section transversale en U, et d'un arceau d'extrémité rapporté sur le corps de boítier en prolongement de sa seconde extrémité tout en laissant une fente périphérique extérieure en arc pour le passage d'une extrémité dépassante du ressort. Les deux extrémités du boítier ainsi constituées viennent à recouvrement sur la tranche externe des premiers ergots de l'articulation. Ainsi, dans cette réalisation, les ergots d'articulation des mors ont tous la même dimension, et les premiers ergots sont coiffés par le boítier qui constitue un tube dans lequel est engagé le ressort hélicoïdal de rappel. Le boítier assure ainsi la continuité visuelle entre les deux premiers ergots, occultant le ressort pour conférer au produit un aspect esthétique agréable à l'oeil.In document EP-A-0 847 710, it has been proposed to incorporate the helical return spring in a housing attached between the first perforated lugs. The case is made by assembly of a main body of a U-shaped cross section, and an end arch attached to the housing body in extension of its second end while leaving a slit external arched device for the passage of one end protruding from the spring. Both ends of the case as well formed overlap on the outer edge of first lugs of the joint. So in this realization, the jaws of the jaws all have the same dimension, and the first lugs are capped by the housing which constitutes a tube in which the helical return spring is engaged. The housing thus ensures visual continuity between the first two pins, obscuring the spring to give the product an appearance aesthetic pleasing to the eye.

Un premier inconvénient est le coût de réalisation relativement élevé du boítier en deux parties ; un autre inconvénient est son assemblage relativement complexe sur les mors de l'article de chevelure. En effet, le boítier doit être réalisé par moulage de matière plastique, et une production en série conduit à concevoir le moulage d'une série de corps et d'arceaux en opposition de part et d'autre d'une carotte principale à laquelle les corps et les arceaux sont reliés par des carottes secondaires. Il est possible de séparer les corps de la carotte principale par rupture de la carotte secondaire. Mais cela n'est pas possible pour les arceaux d'extrémité, car ils sont de dimensions trop petites, plus minces que le diamètre de la carotte principale. Il en résulte que, après injection, les arceaux restent reliés à la carotte principale, les corps restant également reliés à la carotte principale. Il faut donc une opération supplémentaire de décarottage, par découpe des bases des carottes secondaires.A first drawback is the cost of production relatively high housing in two parts; another drawback is its relatively complex assembly on the jaws of the hair article. Indeed, the case must be made by plastic molding, and mass production leads to design the molding of a series of bodies and arches in opposition on either side of a main core to which the bodies and the arches are connected by secondary cores. It is possible to separate the bodies of the main core by secondary core rupture. But this is not possible for the end hoops, because they are too small, thinner than the diameter of the main core. The result that, after injection, the hoops remain connected to the carrot main, the bodies also remaining connected to the carrot main. An additional operation of stripping, by cutting the bases of secondary carrots.

Egalement, il faut un moule complexe pour faire les ergots et les trous d'assemblage de l'arceau sur le corps principal de boítier. Etant donné les dimensions très petites des éléments d'assemblage, les risques de rupture des parties de moule permettant de les réaliser sont grands, et les parties de moule doivent avoir des mouvements spécifiques complexes.Also, you need a complex mold to make the pins and the arch assembly holes on the main body of housing. Given the very small dimensions of the elements assembly, the risk of rupture of the mold parts for making them are large, and the mold parts must have complex specific movements.

La fabrication des pièces est donc onéreuse. Mais également leur assemblage est complexe et onéreux : il faut introduire le ressort dans le corps principal de boítier, puis adapter l'arceau à l'extrémité du corps de boítier, et enfin tendre le ressort et placer le boítier sur le premier mors de l'article de chevelure. L'opération est difficile à automatiser, et conduit à recourir à une main d'oeuvre minutieuse et expérimentée pour l'assemblage.The manufacturing of parts is therefore expensive. But also their assembly is complex and expensive: it is necessary introduce the spring into the main body of the housing, then adapt the arch to the end of the housing body, and finally tighten the spring and place the case on the first jaw of the article of hair. The operation is difficult to automate, and leads to use a meticulous and experienced workforce to assembly.

Le problème proposé par la présente invention est à la fois de supprimer le caractère apparent du ressort hélicoïdal de rappel des mors d'un article de chevelure, de faciliter le montage du ressort sur l'article de chevelure, de réduire le coût de production des pièces constituant l'article de chevelure, et de réduire le coût de montage de l'article de chevelure.The problem proposed by the present invention is to times to remove the apparent character of the coil spring from reminder of the jaws of a hair item, to facilitate assembly of the spring on the article of hair, to reduce the cost of production of the pieces constituting the article of hair, and reduce the cost of mounting the article of hair.

L'idée qui est à la base de l'invention consiste à loger le ressort de rappel dans un boítier, ce qui facilite l'assemblage ultérieur du ressort sur les mors de l'article de chevelure, et à utiliser pour cela un boítier en une seule partie, dépourvu d'arceau d'extrémité, réduisant ainsi la difficulté d'assemblage et le coût de production des pièces.The idea which is the basis of the invention consists in housing the return spring in a housing, which facilitates assembly subsequent spring on the jaws of the hair article, and to use a single-piece case for this, without end bar, thus reducing the difficulty of assembly and the cost of producing the parts.

Pour atteindre ces objets ainsi que d'autres, on utilise un boítier plus court, dont l'une des extrémités seulement recouvre la tranche externe de l'un des premiers ergots du premier mors, tandis que l'autre extrémité du boítier vient seulement en appui contre l'autre premier ergot du premier mors sans le recouvrir, et l'on prévoit que ledit autre premier ergot du premier mors est surdimensionné pour venir en continuité de la face périphérique du boítier, constituant ainsi une continuité visuelle et une occultation du ressort.To reach these and other objects, we use a shorter case, one end of which only covers the outer edge of one of the first pins of the first jaw, while the other end of the case only comes to rest against the other first lug of the first bit without covering it, and it is expected that said other first lug of the first jaw is oversized to come in continuity with the peripheral face of the housing, thus constituting visual continuity and occultation of the spring.

Ainsi, dans un article de chevelure selon l'invention :

  • un premier mors et un second mors sont articulés l'un à l'autre par des moyens d'articulation autorisant leur pivotement respectif autour d'un axe d'articulation transversal entre une position écartée et une position rapprochée,
  • un ressort en fil élastiquement flexible est enroulé en hélice autour de l'axe d'articulation et comporte deux extrémités radialement dépassantes adaptées pour solliciter respectivement le premier et le second mors l'un par rapport à l'autre vers l'une des positions écartée ou rapprochée,
  • les moyens d'articulation comprennent, sur le premier mors, deux premiers ergots perforés parallèles espacés l'un de l'autre selon un écartement de stabilisation, et, sur le second mors, deux seconds ergots perforés parallèles espacés l'un de l'autre selon un écartement approprié pour s'engager de part et d'autre des premiers ergots perforés, avec un arbre de liaison orienté selon l'axe d'articulation transversal et traversant les quatre ergots perforés pour relier les mors,
  • un boítier est rapporté entre les premiers ergots perforés, retenu en position fixe sur le premier mors et formant un logement interne axial contenant au moins la portion enroulée en hélice du ressort, la première extrémité radialement dépassante du ressort étant engagée en appui fixe sur le boítier ou sur le premier mors, la seconde extrémité radialement dépassante du ressort sortant du boítier pour porter en appui fonctionnel contre le second mors et pour le solliciter vers la position rapprochée, le boítier ayant des extrémités comportant des ouvertures axiales pour laisser le passage de l'arbre de liaison,
  • le boítier comporte une paroi latérale périphérique à surface externe généralement cylindrique et sa première extrémité est prolongée par un rebord sur trois de ses côtés pour envelopper au moins en partie la tranche externe du premier ergot perforé correspondant,

Thus, in a hair article according to the invention:
  • a first jaw and a second jaw are articulated to each other by articulation means allowing their respective pivoting about a transverse articulation axis between a separated position and a close position,
  • an elastically flexible wire spring is wound in a helix around the articulation axis and has two radially protruding ends adapted to urge the first and second jaws respectively relative to one another towards one of the separated positions or close together,

  • a housing is attached between the first perforated lugs, retained in a fixed position on the first jaw and forming an axial internal housing containing at least the helically wound portion of the spring, the first radially protruding end of the spring being engaged in fixed support on the housing or on the first jaw, the second radially protruding end of the spring exiting the housing to bear in functional support against the second jaw and to urge it towards the close position, the housing having ends having axial openings to allow passage of the connecting tree,
  • the housing has a peripheral side wall with generally cylindrical external surface and its first end is extended by a rim on three of its sides to at least partially wrap the external edge of the corresponding first perforated lug,
  • the second end of the housing has no rim, and has an end notch for the passage and movement of the second radially protruding end of the spring,
  • the other first perforated lug of the first jaw is oversized so that its outer edge is substantially in continuity with the outer surface of the side wall of the housing.

Le boítier est de préférence réalisé d'une seule pièce.The housing is preferably made in one piece.

Selon un mode de réalisation avantageux, les seconds ergots perforés portés par le second mors sont surdimensionnés de telle façon que leurs tranches externes respectives soient sensiblement en continuité de la surface externe de paroi latérale du boítier.According to an advantageous embodiment, the second perforated pins carried by the second jaw are oversized by so that their respective external slices are substantially in continuity with the external surface of the side wall of the case.

La surface externe de paroi latérale du boítier a de préférence la forme d'un secteur de cylindre de révolution. On assure ainsi une meilleure continuité visuelle avec les ergots perforés, dans toutes les positions angulaires des mors l'un par rapport à l'autre.The outer side wall surface of the housing has preferably the shape of a cylinder of revolution sector. We thus ensures better visual continuity with the pins perforated, in all the angular positions of the jaws one by compared to each other.

Dans les modes de réalisation illustrés sur les figures, un article de chevelure selon l'invention est une pince à cheveux comprenant un premier mors 1 actionnable par un premier levier d'ouverture 2 auquel il est solidarisé selon une première zone de liaison intermédiaire 3, et un second mors 4 actionnable par un second levier d'ouverture 5 auquel il est solidarisé par une seconde zone de liaison intermédiaire 6.In the embodiments illustrated in the figures, a hair article according to the invention is a hair clip comprising a first jaw 1 actuable by a first lever opening 2 to which it is secured according to a first zone of intermediate link 3, and a second jaw 4 actuable by a second opening lever 5 to which it is secured by a second intermediate connection zone 6.

Des moyens d'articulation 7 relient la première zone de liaison intermédiaire 3 et la seconde zone de liaison intermédiaire 6, pour autoriser le pivotement respectif du premier mors 1 et du second mors 4 l'un par rapport à l'autre autour d'un axe d'articulation transversal 8 entre une position écartée représentée sur la figure 3 et une position rapprochée représentée sur la figure 2. Des moyens élastiques sollicitent en pivotement le premier mors 1 et le second mors 4 l'un par rapport à l'autre pour les ramener vers leur position rapprochée dans laquelle les dents 35, 36 respectives se croisent.Hinge means 7 connect the first zone of intermediate link 3 and the second intermediate link area 6, to authorize the respective pivoting of the first jaw 1 and of the second jaw 4 relative to each other about an axis transverse articulation 8 between a separated position shown in Figure 3 and a close-up position shown in the Figure 2. Elastic means pivotally urge the first jaw 1 and the second jaw 4 relative to each other for bring them back to their close position in which the teeth 35, 36 respectively intersect.

Les moyens d'articulation utilisés selon l'invention sont mieux visibles sur les figures 11 et 12, sur lesquelles les moyens élastiques ne sont pas encore adaptés sur les mors 1 et 4. Ces moyens d'articulation 7 comprennent, sur le premier mors 1, deux premiers ergots perforés 9 et 10, parallèles et espacés l'un de l'autre selon un écartement E de stabilisation. Les moyens d'articulation 7 comprennent, sur le second mors 4, deux seconds ergots perforés 11 et 12, parallèles et espacés l'un de l'autre selon un écartement approprié pour s'engager de part et d'autre des premiers ergots perforés 9 et 10. Un arbre de liaison 13, orienté selon l'axe d'articulation transversal 8, traverse les quatre ergots perforés pour relier les mors 1 et 4.The articulation means used according to the invention are better visible in FIGS. 11 and 12, in which the means elastics are not yet adapted on jaws 1 and 4. These articulation means 7 comprise, on the first jaw 1, two first perforated pins 9 and 10, parallel and spaced one of the other according to a stabilization spacing E. Ways articulation 7 include, on the second jaw 4, two seconds perforated pins 11 and 12, parallel and spaced from each other at an appropriate spacing to engage on either side of the first perforated pins 9 and 10. A connecting shaft 13, oriented along the transverse articulation axis 8, crosses the four perforated pins to connect jaws 1 and 4.

Comme on le voit sur la figure 1, les moyens d'articulation 7 comprennent en outre un ressort 14 en fil élastiquement flexible enroulé en hélice autour de l'axe d'articulation transversal 8 et comportant deux extrémités radialement dépassantes telle que la seconde extrémité 15. Le ressort 14 sollicite, par ses extrémités radialement dépassantes, le premier mors 1 et le second mors 4 en pivotement l'un par rapport à l'autre autour de l'axe d'articulation transversal 8.As seen in Figure 1, the means articulation 7 further comprise a wire spring 14 elastically flexible wound helically around the axis transverse joint 8 and having two ends radially protruding such as the second end 15. The spring 14 urges, by its radially projecting ends, the first jaw 1 and the second jaw 4 pivoting one by relation to each other around the transverse articulation axis 8.

Selon l'invention, le ressort 14 est logé dans un boítier 16, rapporté entre les premiers ergots perforés 9 et 10 et solidarisé au premier mors 1.According to the invention, the spring 14 is housed in a housing 16, reported between the first perforated pins 9 and 10 and secured to the first jaw 1.

Le boítier 16 comprend une paroi périphérique ayant une partie externe cylindrique 26 et ayant une face d'appui 27 plane conformée pour venir en appui contre une face plane correspondante 28 du premier mors en position assemblée du boítier 16 sur le premier mors 1. La première extrémité radialement dépassante 17 du ressort 14 est solidaire du boítier 16, et donc solidaire du premier mors 1. La seconde extrémité radialement dépassante 15 du ressort 14 sort radialement du boítier 16 en étant engagée dans une encoche d'extrémité 18 du boítier 16 pour porter en appui fonctionnel contre le second mors 4, comme le représentent les figures 1 et 2. The housing 16 comprises a peripheral wall having a cylindrical outer part 26 and having a flat bearing face 27 shaped to bear against a corresponding flat face 28 of the first jaw in the assembled position of the housing 16 on the first jaw 1. The first radially protruding end 17 of the spring 14 is integral with the housing 16, and therefore integral with the first jaw 1. The second radially protruding end 15 of the spring 14 emerges radially from the housing 16 while being engaged in a end notch 18 of the housing 16 for bearing support functional against the second jaw 4, as shown by Figures 1 and 2.

L'encoche d'extrémité 18 du boítier 16 autorise un débattement angulaire de la seconde extrémité radialement dépassante 15 du ressort 14 autour de l'axe d'articulation transversal 8.The end notch 18 of the housing 16 allows a angular travel of the second end radially protruding 15 from the spring 14 around the axis of articulation transverse 8.

Le boítier 16 comprend une première extrémité 19 et une seconde extrémité 20 ayant chacune une face transversale respective 119 ou 120 conformée pour venir en appui contre les faces intérieures en regard correspondantes 21 et 22 (figure 12) des premiers ergots perforés 9 et 10 correspondants. Dans la première extrémité 19, la première face transversale 119 est associée à un rebord 23 sur trois côtés, pour envelopper au moins en partie la tranche externe 109 du premier ergot perforé 9. Le côté inférieur 25 de la première face transversale 119 de la première extrémité 19 est dépourvu de rebord. Ainsi, comme on le voit sur les figures 11 et 12, le boítier 16 peut être engagé en force par coulissement entre les premiers ergots perforés 9 et 10, ses faces transversales 119 et 120 des extrémités 19 et 20 venant glisser sur les faces intérieures 21 et 22 des premiers ergots perforés 9 et 10 tandis que le rebord 23 glisse sur la tranche latérale du premier ergot perforé 9. En position assemblée, illustrée sur les figures 1 et 2, le boítier 16 est ainsi maintenu tant en translation qu'en rotation sur le premier mors 1, et est retenu par le ressort 14 engagé autour de l'arbre de liaison 13.The housing 16 includes a first end 19 and a second end 20 each having a respective transverse face 119 or 120 shaped to bear against the faces interior facing corresponding 21 and 22 (Figure 12) of first perforated pins 9 and 10 corresponding. In the first end 19, the first transverse face 119 is associated with a rim 23 on three sides, to at least partially wrap the outer edge 109 of the first perforated lug 9. The lower side 25 of the first transverse face 119 of the first end 19 has no edge. So, as seen in Figures 11 and 12, the housing 16 can be engaged in force by sliding between the first perforated pins 9 and 10, its transverse faces 119 and 120 of the ends 19 and 20 sliding on the faces interior 21 and 22 of the first perforated pins 9 and 10 while the rim 23 slides on the lateral edge of the first lug perforated 9. In the assembled position, illustrated in FIGS. 1 and 2, the housing 16 is thus maintained both in translation and in rotation on the first jaw 1, and is retained by the spring 14 engaged around the connecting shaft 13.

Le boítier 16 comprend un logement interne axial 161 tubulaire, ouvert à ses extrémités pour le passage de l'arbre de liaison 13, et conformé pour recevoir et retenir le ressort 14 et bloquer en rotation sa première extrémité radialement dépassante 17 logée dans son fond.The housing 16 includes an axial internal housing 161 tubular, open at its ends for the passage of the shaft link 13, and shaped to receive and retain the spring 14 and rotationally block its first radially protruding end 17 housed in its background.

Comme on le voit mieux sur les figures 5 à 8, le boítier 16 comporte une rainure longitudinale 164, autorisant l'engagement de la première extrémité radialement dépassante 17 du ressort 14. Ainsi, le ressort 14 peut être engagé dans le logement interne axial 161 par coulissement axial depuis la seconde extrémité. La seconde extrémité du boítier 16 comporte un épaulement 167 oblique se développant depuis le fond et sur lequel peut reposer la seconde extrémité radialement dépassante 15 du ressort 14. L'épaulement 167 forme la première extrémité de l'encoche d'extrémité 18. As best seen in Figures 5 to 8, the housing 16 has a longitudinal groove 164, allowing engagement of the first radially protruding end 17 of the spring 14. Thus, the spring 14 can be engaged in the internal housing axial 161 by axial sliding from the second end. The second end of the housing 16 has an oblique shoulder 167 developing from the bottom and on which the second can rest radially protruding end 15 of the spring 14. The shoulder 167 forms the first end of the end notch 18.

Il peut s'avérer utile de prévoir, sur le ressort 14, une première extrémité radialement dépassante 17 coudée à tronçon axial, comme illustré sur les figures 5 à 9. On répartit ainsi sur une plus grande surface la force d'appui du ressort sur le boítier, ce qui réduit l'usure du boítier et le risque d'apparition d'un jeu.It may be useful to provide, on the spring 14, a first radially protruding end 17 angled to section axial, as illustrated in FIGS. 5 to 9. We thus distribute over a greater surface area, the bearing force of the spring on the housing, which reduces wear and tear on the case and the risk of Game.

Selon l'invention, la seconde extrémité 20 du boítier 16 est dépourvue de rebord, et comporte une encoche d'extrémité 18 pour le passage et le déplacement de la seconde extrémité radialement dépassante 15 du ressort 14. La seconde extrémité 20 vient simplement en appui contre l'autre premier ergot perforé 10.According to the invention, the second end 20 of the housing 16 has no rim, and has an end notch 18 for passing and moving the second end radially protruding 15 from the spring 14. The second end 20 simply bears against the other first perforated lug 10.

Selon l'invention, pour assurer une continuité visuelle du système d'articulation entre les ergots, l'autre premier ergot perforé 10 du premier mors 1 est surdimensionné de telle façon que sa tranche externe 110 soit sensiblement en continuité de la surface externe de paroi latérale du boítier 16.According to the invention, to ensure visual continuity of the articulation system between the lugs, the other first lug perforated 10 of the first jaw 1 is oversized so that its outer edge 110 is substantially in continuity with the outer surface of the side wall of the housing 16.

Selon un premier mode de réalisation, seul l'autre premier ergot perforé 10 du premier mors 1 est surdimensionné. Il en résulte que les seconds ergots perforés 11 et 12 sont plus petits que le boítier 16, et restent en retrait.According to a first embodiment, only the other first perforated lug 10 of the first jaw 1 is oversized. It results that the second perforated pins 11 and 12 are smaller as the housing 16, and remain recessed.

Selon un autre mode de réalisation, on peut prévoir que les seconds ergots perforés 11 et 12 portés par le second mors 4 sont également surdimensionnés, de telle façon que leurs tranches externes 111 et 112 respectives soient sensiblement en continuité de la surface externe de paroi latérale du boítier 16.According to another embodiment, it can be provided that the second perforated lugs 11 and 12 carried by the second jaw 4 are also oversized, so that their slices 111 and 112 respectively are substantially continuous of the external surface of the side wall of the housing 16.

En d'autres termes, on peut considérer que les mors 1 et 4 comprennent trois ergots perforés 10, 11 et 12 de taille normale, et un ergot perforé 9 de taille réduite pour s'engager dans le logement d'extrémité délimité par le rebord 23.In other words, we can consider that jaws 1 and 4 include three perforated pins 10, 11 and 12 of normal size, and a small size perforated lug 9 for engaging in the end housing delimited by the rim 23.

De préférence, la surface externe de paroi latérale du boítier 16 a la forme d'un secteur de cylindre de révolution, comme illustré sur les figures, et est centrée sur l'axe d'articulation transversal 8.Preferably, the outer side wall surface of the box 16 has the shape of a cylinder of revolution sector, as illustrated in the figures, and is centered on the hinge axis transverse 8.

Les extrémités 19 et 20 du boítier 16 comportent chacune une face transversale 119 et 120 en appui contre les faces intérieures 21 et 22 en regard des premiers ergots perforés 9 et 10 correspondants. The ends 19 and 20 of the housing 16 each have a transverse face 119 and 120 bearing against the faces interior 21 and 22 opposite the first perforated pins 9 and 10 correspondents.

Le boítier 16 est avantageusement réalisé en matière plastique moulée par injection, et est constitué d'une seule pièce.The housing 16 is advantageously made of material injection molded plastic, and is made in one piece.

Pour l'adaptation du boítier 16 sur le premier mors 1, on déplace le boítier 16 par translation dans le sens de la flèche 29 illustrée sur la figure 11, en orientant le boítier 16 avec sa face d'appui 27 en avant et en maintenant les mors avec les trous des ergots perforés 9-12 en alignement. Dans cette orientation, le boítier 16 coulisse entre les premiers ergots perforés 9 et 10, et la seconde extrémité radialement dépassante 15 du ressort 14 vient en appui sur la face intérieure 30 du second mors 4. Ainsi, la seconde extrémité radialement dépassante 15 du ressort est repoussée et pivote comme illustrée sur la figure 11 par les pointillés référencés 31. En fin d'engagement du boítier 16 sur les premiers ergots perforés 9 et 10, la seconde extrémité radialement dépassante 15 du ressort 14 vient éventuellement s'engager dans un logement 32 ménagé sur la face intérieure 30 du second mors 4, le ressort 14 se trouvant précontraint.For the adaptation of the housing 16 on the first jaw 1, we moves the housing 16 by translation in the direction of the arrow 29 illustrated in Figure 11, orienting the housing 16 with its face support 27 forward and holding the jaws with the holes of the perforated lugs 9-12 in alignment. In this orientation, the box 16 slides between the first perforated pins 9 and 10, and the second radially protruding end 15 of the spring 14 comes resting on the inner face 30 of the second jaw 4. Thus, the second radially protruding end 15 of the spring is pushed back and pivots as illustrated in figure 11 by the dotted lines referenced 31. At the end of engagement of the housing 16 on the first perforated pins 9 and 10, the second end radially protruding 15 from the spring 14 possibly engages in a housing 32 formed on the inner face 30 of the second jaw 4, the spring 14 being prestressed.

De préférence, le boítier 16 est en une matière opaque, pour occulter le ressort 14 qu'il contient. De la sorte, comme illustré sur la figure 1, les moyens d'articulation 7 présentent un aspect relativement continu, beaucoup plus esthétique qu'un ressort hélicoïdal nu.Preferably, the housing 16 is made of an opaque material, to conceal the spring 14 which it contains. So, like illustrated in FIG. 1, the articulation means 7 have a relatively continuous appearance, much more aesthetic than a spring helical naked.

Dans les modes de réalisation précédemment décrits, le boítier 16 permet à la fois d'occulter le ressort 14 et de faciliter le montage de l'article de chevelure.In the embodiments previously described, the box 16 allows both to conceal the spring 14 and facilitate assembly of the article of hair.

Grâce à son coût de réalisation et d'assemblage réduit, et grâce à l'absence de pièces ou parties de pièces de dimensions trop réduites, le dispositif selon l'invention peut être économiquement utilisé sur tous types d'articles de chevelures, y compris sur les articles de chevelures miniaturisés à bas prix.Thanks to its reduced production and assembly cost, and thanks to the absence of parts or parts of parts too large reduced, the device according to the invention can be economically used on all types of hair items, including on low-priced miniaturized hair items.

La présente invention n'est pas limitée aux modes de réalisation qui ont été explicitement décrits, mais elle en inclut les diverses variantes et généralisations contenues dans le domaine des revendications ci-après.The present invention is not limited to the modes of which have been explicitly described, but it includes the various variants and generalizations contained in the field of the claims below.
