Abstract

The hairclip comprises a pair of jaws (1) activated by an opening lever (2) to which they are fixed along a first intermediate connecting zone (3). A second pair of jaws (4) are activated by a second opening lever (5) to which they are fixed by a second intermediate connection zone (6). A pivot (7) connects the first and second connecting zones to allow relative pivoting of the jaws about a transverse axis (8), between separated and clamped positions. Two open spring rings (13,14) are axially located around the pivoting axis and pass through slots (22-25) in levers (2,5). The rings are supported in housings on the external faces of the jaws. The pivot comprises holed lugs, which overhang the two intermediate connecting zones, which are covered by the rings. A tubular part covers the shaft connecting the series of lugs

Description

La présente invention concerne les pinces à cheveux, notamment utilisées pour la coiffure féminine.The present invention relates to hair clips, in particular used for female hairstyle.

Les pinces à cheveux connues, telles que décrites notamment dans les documents FR-A-770 805, FR-A-755 662 ou US-A-2 201 719, comprennent généralement un premier mors actionnable par un premier levier d'ouverture auquel il est solidarisé selon une première zone de liaison intermédiaire, et un second mors actionnable par un second levier d'ouverture auquel il est solidarisé par une seconde zone de liaison intermédiaire. Des moyens d'articulation relient la première et la seconde zones de liaison intermédiaires, pour autoriser le pivotement respectif du premier mors et du second mors l'un par rapport à l'autre autour d'un axe d'articulation transversal entre une position écartée et une position serrée. Des moyens élastiques sollicitent en pivotement le premier et le second mors l'un par rapport à l'autre vers leur position serrée.Known hair clips, as described in particular in documents FR-A-770 805, FR-A-755 662 or US-A-2 201 719, generally comprise a first jaw actuated by a first opening lever to which it is secured according to a first intermediate connection zone, and a second jaw actuable by a second opening lever to which it is secured by a second intermediate connection zone. Articulation means connect the first and the second intermediate connection zones, to allow the respective pivoting of the first jaw and of the second jaw relative to each other about a transverse articulation axis between a spaced position and a tight position. Elastic means pivotally bias the first and second jaws relative to each other towards their tight position.

Dans ces pinces à cheveux connues, les moyens élastiques comprennent un ressort constitué d'un fil métallique élastique hélicoïdal enroulé autour de l'axe d'articulation transversal. Une première extrémité du fil métallique se prolonge radialement à l'écart de l'axe et vient en appui sur la face interne du premier levier d'ouverture. La seconde extrémité du fil métallique se prolonge radialement à l'écart de l'axe et vient en appui sur la face interne du second levier d'ouverture. Le ressort est précontraint en rotation autour de l'axe, de sorte que ses deux extrémités dépassantes sollicitent les leviers d'ouverture à l'écart l'un de l'autre, en repoussant ainsi les mors vers leur position serrée.In these known hair clips, the elastic means comprise a spring constituted by a helical elastic metal wire wound around the transverse articulation axis. A first end of the metal wire extends radially away from the axis and comes to bear on the internal face of the first opening lever. The second end of the metal wire extends radially away from the axis and comes to bear on the internal face of the second opening lever. The spring is prestressed in rotation around the axis, so that its two protruding ends urge the opening levers away from each other, thus pushing the jaws towards their tight position.

Un premier inconvénient d'une telle structure est qu'elle nécessite l'utilisation d'un fil métallique formé en ressort hélicoïdal à spires jointives. Les spires jointives constituent une pluralité de fentes ou de logements de faible dimension dans lesquels l'eau et les autres produits liquides peuvent stagner. Au cours d'une utilisation de longue durée, le fil métallique est ainsi susceptible d'être corrodé par l'humidité et les différents produits utilisés en coiffure.A first drawback of such a structure is that it requires the use of a metal wire formed as a helical spring with contiguous turns. The contiguous turns constitute a plurality of small slots or housings in which water and other liquid products can stagnate. During long-term use, the metal wire is thus liable to be corroded by humidity and the various products used in hairdressing.

Un second inconvénient d'une telle structure est que le ressort est nécessairement précontraint en position serrée, de façon à présenter une force suffisante de serrage de la pince, depuis la position écartée. Il peut alors se produire, lors de traitements thermiques de la pince au cours des finitions, que les extrémités de ressort pénètrent dans les bras d'articulation en matière plastique, et les déforment, si la matière plastique est suffisamment ramollie par la chaleur. Le fonctionnement ultérieur de la pince est alors défectueux.A second drawback of such a structure is that the spring is necessarily prestressed in the clamped position, so as to present a sufficient force for clamping the clamp, from the separated position. It can then occur, during heat treatments of the clamp during finishing, that the spring ends penetrate into the arms of plastic, and deform them, if the plastic is sufficiently softened by heat. The subsequent operation of the clamp is then defective.

Un inconvénient très important de cette structure connue résulte de l'utilisation particulière de telles pinces, qui, lorsqu'elles sont positionnées dans une coiffure, laissent généralement apparente leur partie postérieure, c'est-à-dire la partie constituée par les deux faces internes des leviers d'ouverture, par la face postérieure de la zone d'articulation, et par le fil métallique élastique. Il en résulte un effet particulièrement inesthétique, d'autant que la structure de ressort, en fil métallique, est clairement apparente et donne un aspect d'organe mécanique à une pince à cheveux qui devrait principalement constituer un objet de parure et d'ornement.A very important drawback of this known structure results from the particular use of such pliers, which, when positioned in a hairstyle, generally leave their posterior part visible, that is to say the part constituted by the two faces. internal opening levers, by the rear face of the articulation zone, and by the elastic metal wire. This results in a particularly unsightly effect, especially since the spring structure, made of metal wire, is clearly visible and gives the appearance of a mechanical organ to a hair clip which should mainly constitute an object of adornment and ornament.

Une autre structure connue de pince à cheveux, décrite dans le document EP-A-0 516 564, comprend des moyens d'articulation à parties engageantes mâles et femelles, et des pièces ressort particulières moulées à profil général en U avec des branches longitudinales et des parties d'accrochage. La réalisation et le montage des pièces ressort moulées de formes particulières augmentent le coût de production.Another known structure of a hair clip, described in document EP-A-0 516 564, comprises articulation means with engaging male and female parts, and particular spring parts molded with a general U-shaped profile with longitudinal branches and hooking parts. The production and assembly of molded spring parts of particular shapes increases the production cost.

Le problème proposé par la présente invention est de supprimer l'utilisation de tels moyens élastiques constitués d'un ressort en fil métallique hélicoïdal susceptible d'être apparent sur la face postérieure de la pince, de façon à éviter les inconvénients de ces structures connues de pinces. On cherche à réaliser une pince dont la face apparente présente un aspect esthétique satisfaisant, les diverses parties de la pince pouvant être décorées, tout en conservant une fonction de serrage satisfaisante des mors de la pince.The problem proposed by the present invention is to eliminate the use of such elastic means consisting of a helical wire spring which may be apparent on the rear face of the clamp, so as to avoid the drawbacks of these known structures. pliers. It is sought to produce a clamp whose apparent face has a satisfactory aesthetic appearance, the various parts of the clamp can be decorated, while retaining a satisfactory clamping function of the jaws of the clamp.

Egalement, la structure de pince selon l'invention doit pouvoir être produite à faible coût, et doit notamment être assemblée de façon rapide et simple.Also, the clamp structure according to the invention must be able to be produced at low cost, and must in particular be assembled quickly and simply.

Pour atteindre ces objets ainsi que d'autres, la structure de pince à cheveux selon l'invention comprend, de façon connue, un premier mors et un second mors articulés l'un à l'autre et actionnés par des leviers d'ouverture, avec des moyens d'articulation autorisant leur pivotement entre les positions écartée et serrée, et avec des moyens élastiques qui les sollicitent vers la position serrée. La pince selon l'invention comprend des moyens d'articulation et des moyens élastiques particuliers.To achieve these and other objects, the hair clip structure according to the invention comprises, in a known manner, a first jaw and a second jaw articulated to each other and actuated by opening levers, with articulation means allowing their pivoting between the separated and tight positions, and with elastic means which urge them towards the tight position. The pliers according to the invention comprises articulation means and specific elastic means.

Les moyens d'articulation comprennent un premier et un second ergots perforés dépassant respectivement de la première et de la seconde zone de liaison intermédiaire et à proximité l'un de l'autre transversalement selon l'axe d'articulation, un troisième et un quatrième ergots perforés dépassant respectivement de la première et de la seconde zones de liaison intermédiaires et à proximité l'un de l'autre transversalement selon l'axe d'articulation tout en étant transversalement espacés des deux premiers ergots perforés, et un arbre de liaison traversant les perforations des quatre ergots perforés pour relier les deux mors.The articulation means comprise a first and a second perforated lugs projecting respectively from the first and from the second intermediate connection zone and close to one another transversely along the articulation axis, a third and a fourth perforated pins projecting respectively from the first and second intermediate connection zones and in proximity to one another transversely along the axis of articulation while being transversely spaced from the first two perforated pins, and a connecting connecting shaft the perforations of the four perforated pins to connect the two jaws.

Les moyens élastiques comprennent deux anneaux élastiques identiques ouverts à section plate, disposés autour de l'axe de rotation et coaxialement l'un à l'autre selon un axe transversal parallèle à l'axe de rotation. Leurs deux extrémités respectives viennent en appui dans des logements correspondants ménagés sur la face externe des zones de liaison intermédiaires des mors en avant de l'axe d'articulation. Leurs parties intermédiaires traversent des lumières correspondantes ménagées dans les leviers d'ouverture, et viennent entourer les deux groupes d'ergots perforés entre lesdits leviers.The elastic means comprise two identical elastic rings open in flat section, arranged around the axis of rotation and coaxially with one another along a transverse axis parallel to the axis of rotation. Their two respective ends come to bear in corresponding housings formed on the external face of the intermediate connection zones of the jaws in front of the articulation axis. Their intermediate parts pass through corresponding openings made in the opening levers, and come to surround the two groups of lugs perforated between said levers.

Avec une telle structure, les deux anneaux élastiques recouvrent les ergots perforés d'articulation sur la face postérieure de la pince. En regardant la pince depuis la face postérieure, on voit ainsi les deux anneaux élastiques, ainsi que l'arbre de liaison. En eux-mêmes, ces éléments présentent un aspect beaucoup plus agréable que le ressort à fil métallique hélicoïdal à extrémités dépassantes qui était visible sur les pinces utilisées jusqu'alors.With such a structure, the two elastic rings cover the perforated articulation lugs on the rear face of the clamp. Looking at the clamp from the rear side, we can see the two elastic rings, as well as the connecting shaft. In themselves, these elements have a much more pleasant appearance than the helical wire spring with protruding ends which was visible on the clamps used until then.

Les anneaux élastiques ont avantageusement un profil à courbure régulière en C et, en position serrée, le profil à courbure régulière en C est sensiblement circulaire.The elastic rings advantageously have a profile with regular curvature in C and, in the tightened position, the profile with regular curvature in C is substantially circular.

De préférence, les anneaux élastiques présentent une largeur égale ou supérieure à la largeur des groupes d'ergots perforés, pour occulter entièrement les ergots perforés dans la zone d'articulation apparente entre les deux leviers de pince.Preferably, the elastic rings have a width equal to or greater than the width of the groups of perforated lugs, in order to completely obscure the perforated lugs in the area of apparent articulation between the two clamp levers.

Selon un mode de réalisation préféré, on dispose en outre un élément tubulaire engagé sur l'arbre de liaison et reliant les deux groupes d'ergots perforés respectifs, pour occulter l'arbre de liaison dans la zone d'articulation apparente entre les deux leviers. L'élément tubulaire peut lui-même être décoré, et, par sa section plus importante, constitue par lui-même un élément décoratif qui améliore sensiblement l'aspect de la pince.According to a preferred embodiment, there is also a tubular element engaged on the connecting shaft and connecting the two groups of respective perforated pins, to conceal the connecting shaft in the area of apparent articulation between the two levers. The tubular element can itself be decorated, and, by its larger section, constitutes by itself a decorative element which appreciably improves the appearance of the clamp.

Diverses structures de mors peuvent être utilisées avec une telle structure d'articulation et d'éléments élastiques selon l'invention.Various jaw structures can be used with such a hinge structure and elastic elements according to the invention.

The respective ends such as the ends 15 , 16 and 17 of the elastic rings 13 and 14 come to bear in corresponding housings such as the housings 18 and 19 formed on the external face of the intermediate connection zones 3 and 6 of the jaws, in front of the articulation axis 8 .

Les parties intermédiaires 20 et 21 des anneaux élastiques 13 et 14 traversent des lumières correspondantes 22, 23, 24, et 25 ménagées dans les leviers d'ouverture 2 et 5, et viennent entourer les deux groupes d'ergots perforés 9-12, entre lesdits leviers 2 et 5.The intermediate parts 20 and 21 of the elastic rings 13 and 14 pass through corresponding slots 22, 23, 24, and 25 formed in the opening levers 2 and 5, and come to surround the two groups of perforated lugs 9-12, between said levers 2 and 5.

Dans le mode de réalisation représenté sur les figures, les anneaux élastiques 13 et 14 présentent avantageusement une section plate, par exemple la section rectangulaire, et leur largeur est supérieure à la largeur de chacun des groupes d'ergots perforés 9-12, pour occulter entièrement les ergots perforés dans la zone d'articulation apparente entre les deux leviers 2 et 5, comme illustré sur la figure 3.In the embodiment shown in the figures, the elastic rings 13 and 14 advantageously have a flat section, for example the rectangular section, and their width is greater than the width of each of the groups of perforated lugs 9-12, to conceal fully the pins perforated in the area of visible articulation between the two levers 2 and 5, as illustrated in FIG. 3.

Les anneaux élastiques 13 et 14 peuvent être réalisés en métal, ou en toute autre matière présentant les propriétés élastiques recherchées pour obtenir la force de serrage nécessaire des mors 1 et 4 de la pince.The elastic rings 13 and 14 can be made of metal, or any other material having the desired elastic properties to obtain the necessary clamping force of the jaws 1 and 4 of the clamp.

L'articulation est complétée par un arbre de liaison 26, qui traverse les perforations respectives des quatre ergots perforés 9-12 pour relier les deux mors. L'arbre 26 définit l'axe d'articulation 8, et il est visible sur la figure 4. Pour traverser les perforations correspondantes ménagées dans les ergots perforés 9-12, l'arbre 26 est nécessairement de diamètre plus réduit que la taille des ergots perforés 9-12. Il reste donc un espace entre les deux zones de liaison intermédiaires 3 et 6, notamment dans la zone d'écartement E située entre les deux groupes d'ergots perforés 9, 10 et 11, 12. Dans le mode de réalisation représenté sur la figure 3, on améliore sensiblement l'aspect esthétique de la pince, dans sa zone postérieure, en prévoyant un élément tubulaire 27, engagé sur l'arbre de liaison 26, et reliant les deux groupes d'ergots perforés 9, 10 et 11, 12, pour occulter l'arbre de liaison 26 dans la zone d'articulation apparente d'écartement E entre les deux leviers 2 et 5. L'élément tubulaire 27 peut avantageusement être un élément décoré, par exemple d'une teinte différente de celle des leviers 2 et 5, notamment de la même teinte que les anneaux élastiques 13 et 14.The articulation is completed by a connecting shaft 26, which crosses the respective perforations of the four perforated pins 9-12 to connect the two jaws. The shaft 26 defines the hinge axis 8, and it is visible in Figure 4. To pass through the corresponding perforations formed in the perforated lugs 9-12, the shaft 26 is necessarily of smaller diameter than the size of the perforated lugs 9-12. There therefore remains a space between the two intermediate connecting zones 3 and 6, in particular in the spacing zone E situated between the two groups of perforated lugs 9, 10 and 11, 12. In the embodiment shown in the figure 3, the aesthetic appearance of the pliers is substantially improved, in its posterior region, by providing a tubular element 27, engaged on the connecting shaft 26, and connecting the two groups of perforated lugs 9, 10 and 11, 12 , to conceal the connecting shaft 26 in the apparent area of articulation of spacing E between the two levers 2 and 5. The tubular element 27 can advantageously be a decorated element, for example of a color different from that of levers 2 and 5, in particular of the same shade as the elastic rings 13 and 14.

De préférence, les anneaux élastiques 13 et 14 présentent une faible épaisseur, les rendant peu visibles sur leur côté, comme illustré sur les figures 5 et 6. En position serrée, telle que représentée sur la figure 5, les parties intermédiaires 20 et 21 des anneaux élastiques 13 et 14 viennent à proximité des groupes respectifs d'ergots perforés 9, 10 et 11, 12, de façon que les ergots perforés 9-12 soient le moins visibles possible.Preferably, the elastic rings 13 and 14 have a small thickness, making them not very visible on their side, as illustrated in FIGS. 5 and 6. In the clamped position, as shown in FIG. 5, the intermediate parts 20 and 21 of the elastic rings 13 and 14 come close to the respective groups of perforated lugs 9, 10 and 11, 12, so that the perforated lugs 9-12 are as invisible as possible.

Dans le mode de réalisation illustré sur les figures 5 et 6, les anneaux élastiques 13 et 14 présentent en vue de côté un profil à courbure régulière en C : en position serrée sur la figure 5, le profil est sensiblement circulaire ; en position écartée sur la figure 6, le profil est en forme de C ouvert.In the embodiment illustrated in FIGS. 5 and 6, the elastic rings 13 and 14 have a side view of a profile with regular curvature at C: in the clamped position in FIG. 5, the profile is substantially circular; in the separated position in FIG. 6, the profile is in the form of an open C.

Pour éviter les éventuelles déformations des mors 1, 4 en cas de traitement thermique, les anneaux élastiques 13 et 14 sont en appui dans les logements correspondants 18, 19 selon une force de précontrainte faible lorsque la pince est en position serrée. Grâce à la forme en anneau des anneaux élastiques 13 et 14, même lorsque la force de précontrainte est faible en position serrée, les anneaux élastiques 13 et 14 produisent une force de rappel élastique suffisante lorsque la pince est en position écartée. Un tel effet n'était pas obtenu avec les ressorts hélicoïdaux traditionnels.To avoid possible deformations of the jaws 1, 4 in the event of heat treatment, the elastic rings 13 and 14 are supported in the corresponding housings 18, 19 according to a weak prestressing force when the clamp is in the clamped position. Thanks to the ring shape of the elastic rings 13 and 14, even when the prestressing force is low in the tight position, the elastic rings 13 and 14 produce a sufficient elastic restoring force when the clamp is in the separated position. Such an effect was not obtained with traditional coil springs.

Les mors 1 et 4 d'une pince selon l'invention peuvent présenter des formes diverses. Il en est de même des leviers 2 et 5.The jaws 1 and 4 of a clamp according to the invention can have various shapes. The same applies to levers 2 and 5.

Par exemple, sur la figure 1, on a représenté une pince selon l'invention avec des mors 1 et 4 ayant une forme générale en croissant de lune, se développant transversalement c'est-à-dire parallèlement à l'axe de rotation 8. En position serrée, les lèvres antérieures 28 et 29 des mors 1 et 4, viennent en appui l'une contre l'autre selon leur longueur. Pour un meilleur accrochage dans la chevelure, on peut prévoir une série de dents 30 s'imbriquant les unes dans les autres au voisinage des lèvres 28 et 29 antérieures. Dans ce mode de réalisation, les mors 1 et 4 forment une pince généralement plate et large.For example, in Figure 1, there is shown a clamp according to the invention with jaws 1 and 4 having a general crescent moon shape, developing transversely, that is to say parallel to the axis of rotation 8 In the tight position, the front lips 28 and 29 of the jaws 1 and 4 come to bear against one another along their length. For better attachment in the hair, a series of teeth 30 can be provided which overlap one another in the vicinity of the front lips 28 and 29. In this embodiment, the jaws 1 and 4 form a generally flat and wide clamp.

Dans le mode de réalisation de la figure 2, les mors 1 et 4 forment deux séries de dents parallèles telles que les dents 31, incurvées l'une vers l'autre et venant s'imbriquer en position serrée. Le profil longitudinal des dents 31 peut notamment être sensiblement circulaire, comme illustré sur les figures 5 et 6. Lorsque la pince est en position écartée telle que représentée sur la figure 6, les extrémités 32 et 33 des dents sont écartées l'une de l'autre, pour permettre l'introduction dans la chevelure. Lorsque la pince est en position intermédiaire entre la position écartée et la position serrée, les extrémités 32 et 33 des deux séries de dents viennent en regard l'une de l'autre, puis se croisent lorsque la pince vient en position serrée.In the embodiment of FIG. 2, the jaws 1 and 4 form two series of parallel teeth such as the teeth 31, curved towards one another and coming to overlap in the clamped position. The longitudinal profile of the teeth 31 can in particular be substantially circular, as illustrated in FIGS. 5 and 6. When the clamp is in the separated position as shown in FIG. 6, the ends 32 and 33 of the teeth are separated from one of the 'other, to allow the introduction into the hair. When the clamp is in the intermediate position between the separated position and the clamped position, the ends 32 and 33 of the two sets of teeth come opposite one another, then cross when the clamp comes in the clamped position.

Les leviers 2 et 5 peuvent prendre des formes diverses, par exemple une forme en croissant de lune telle qu'illustrée sur les figures 3 et 4, ou une forme plus rectangulaire telle qu'illustrée sur la figure 1, avec des ajourages décoratifs, avec un contour travaillé, ou avec un décor appliqué sur leur face postérieure.Levers 2 and 5 can take various forms, for example a crescent moon shape as illustrated in FIGS. 3 and 4, or a more rectangular shape as illustrated in FIG. 1, with decorative openings, with a worked contour, or with a decoration applied on their posterior face.

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 embodiments which have been explicitly described, but it includes the various variants and generalizations thereof contained in the field of claims below.
