Description

Domaine technique de l'invention :Technical Field of the Invention

La présente invention concerne un appareil électrique de coiffure ou de mise en forme des cheveux, plus particulièrement un appareil pour la mise en volume des cheveux ou bien pour décoller les racines des cheveux. Il s'agit alors de donner une forme lisse et courbée des mèches de cheveux. La présente invention concerne aussi un appareil de mise en forme des cheveux capable dans plusieurs configurations de fonctionnement de produire des mises en forme différentes.The present invention relates to an electric appliance for hairstyling or shaping the hair, more particularly an apparatus for the volume of the hair or to take off the roots of the hair. It is then a question of giving a smooth and curved shape of locks of hair. The present invention also relates to a hair shaping apparatus capable in various operating configurations of producing different shaping.

Etat de la technique antérieure :State of the prior art:

La plupart des appareils de mise en volume des cheveux sont des appareils comportant deux surfaces de traitement chaudes ou chauffées qui viennent en contact sur une mèche de cheveux en passant d'une position d'ouverture permettant l'insertion des cheveux à une position de fermeture pour leur mise en contact entre les deux surfaces.Most hair volume enhancers are devices having two hot or heated treatment surfaces that contact a lock of hair from an open position for insertion of the hair to a closed position. for putting them in contact between the two surfaces.

Il est connu de WO2007094550 un fer à friser avec plusieurs mandrins chauffants détachables de section différente (circulaire, rectangulaire, hexagonale, octogonale...), positionnés en regard de et amenés en position fermée en contact avec une plaque en U chauffée et recouvrant les trois quarts du mandrin. Ceci permet de former des ondulations différentes selon la forme du mandrin attaché. Pour former de façon efficace des ondulations, il est prévu que le mandrin soit en contact avec les cheveux sur un maximum de circonférence : on constate que les trois quarts du mandrin sont en contact simultané avec la mèche à onduler. Ceci permet de former une plus grande longueur de mèche selon plusieurs formes correspondant à plusieurs mandrins.It is known to WO2007094550 a curling iron with several detachable heating cores of different section (circular, rectangular, hexagonal, octagonal ...), positioned opposite and brought into closed position in contact with a heated U plate and covering three quarters of the mandrel. This makes it possible to form different corrugations according to the shape of the attached mandrel. To effectively form corrugations, it is expected that the mandrel is in contact with the hair over a maximum of circumference: it is found that three quarters of the mandrel are in simultaneous contact with the wick to be corrugated. This makes it possible to form a greater length of wick in several forms corresponding to several mandrels.

Il est connu de WO2007100842 un outil de coiffure comprenant un corps, un cylindre s'étendant en provenance du corps, le cylindre chauffant étant rotatif motorisé par rapport au corps et un bras de coiffure attaché de manière pivotante sur le corps. L'outil de coiffure peut avoir une configuration généralement en double coque, le bras de coiffure étant mobile entre une position ouverte dans laquelle le bras de coiffure n'entre pas en contact avec le cylindre et une position fermée dans laquelle le bras de coiffure entre en contact avec le cylindre. Le bras de coiffure peut également comprendre une tête de brosse ayant des poils fixes ou rétractables pour brosser la mèche. La rotation motorisée est essentielle pour lustrer la mèche de cheveux et il est annoncé que selon le mouvement de l'utilisateur, les cheveux peuvent être lissés droits ou ondulés.It is known to WO2007100842 a hairdressing tool comprising a body, a cylinder extending from the body, the heating cylinder being rotatable motorized relative to the body and a hairdressing arm pivotally attached to the body.

La première machoire comprend un rouleau entrainé en rotation et muni de brosses, et deux mini tuiles latérales de chaque côté du rouleau. La deuxième machoire comprend une large tuile montée pour permettre, en position fermée, de venir contre les deux tuiles de la première machoîre pour pincer la mèche et pour permettre aux extrémités des poils de brosses montés sur le rouleau de venir brosser les cheveux pincés sans que la surface extérieure du rouleau ne vienne en contact avec la large tuile. Seules les courbes des deux tuiles latérales sont prévues complémentaires avec la courbe de la large tuile.He is finally known US2011 / 0220141 describing an apparatus for forming hair comprising a first jaw and a second jaw pivoting relative to each other between two positions.

Cette configuration en contre forme permet de créer en statique une ondulation particulièrement durable à un emplacement choisi de la mèche, par exemple créer un décollement à la racine de la mèche, sans endommager le cuir chevelu.This makes it possible to create a counter shape on the wick treated statically, against a shape that can be localized for example at the root, while keeping a natural shape. The user indeed chooses whether it keeps the device static in the closed position or if it slides the device along the wick with the rotational speed of the chuck adapted to the drive speed of the device. This counter-shaped configuration makes it possible to statically create a particularly durable corrugation at a chosen location of the wick, for example to create a detachment at the root of the wick, without damaging the scalp.

Les deux surfaces de traitement vont créer une zone de traitement en pinçant les cheveux car elles sont montées en regard l'une de l'autre en position fermée et leur écartement faible ou nul en position fermée permet de glisser l'appareil le long de la mèche en usage. Le mandrin peut être un cylindre, particulièrement un cylindre de révolution.The two treatment surfaces will create a treatment area by pinching the hair because they are mounted facing each other in the closed position and their spacing low or zero in the closed position allows the device to slide along the wick in use. The mandrel may be a cylinder, particularly a cylinder of revolution.

Selon l'invention, l'angle de recouvrement α peut être plus précisément compris entre 170° et 185°, préférentiellement égal à environ 180°. La valeur de 180° permet de produire un appareil symétrique utilisable par droitier ou gaucher indifféremment et dans tous les sens.According to the invention, the recovery angle α can be more precisely between 170 ° and 185 °, preferably equal to about 180 °. The value of 180 ° makes it possible to produce a symmetrical apparatus that can be used by right-handed or left-handed person, indifferently and in all directions.

Selon l'invention, au moins un des deux bords longitudinaux de la plaque peut présenter une épaisseur (e) comprise entre 2 et 6mm. Cette faible épaisseur qui épouse le mandrin permet de former une courbe prononcée au plus proche de la racine et avec une forme la plus naturelle possible. Particulièrement, les deux bords longitudinaux de la plaque peuvent présenter chacun une épaisseur (e) comprise entre 2 et 6mm. Ceci permet qu'un droitier ou gaucher puisse indifféremment travailler au plus près de la racine.
Selon l'invention, au moins un des deux bords longitudinaux de la plaque peut être au même niveau que le bord adjacent du premier boitier. Ceci signifie qu'aucun des deux bords de la plaque et du boitier ne serait protubérant vers les cheveux. Lorsque les 4 bords sont au même niveau et que la plaque recouvre une demi circonférence du mandrin, chacun des deux bords longitudinaux de la plaque et chacun des deux bords longitudinaux du premier boitier sont sensiblement coplanaires. Ceci permet de réduire l'encombrement de l'appareil.According to the invention, at least one of the two longitudinal edges of the plate may have a thickness (e) of between 2 and 6 mm. This small thickness that follows the mandrel makes it possible to form a pronounced curve closer to the root and with a form as natural as possible. In particular, the two longitudinal edges of the plate may each have a thickness (e) of between 2 and 6 mm. This allows that a right-handed or left-handed person can indifferently work closer to the root.
According to the invention, at least one of the two longitudinal edges of the plate can be at the same level as the adjacent edge of the first housing. This means that neither of the two edges of the plate and the case would protrude towards the hair. When the 4 edges are at the same level and the plate covers a half circumference of the mandrel, each of the two longitudinal edges of the plate and each of the two longitudinal edges of the first housing are substantially coplanar. This reduces the size of the device.

Selon l'invention, au moins un des deux bords longitudinaux de la plaque peut être protubérant par rapport au bord adjacent du premier boitier. Ceci est une alternative aux bords de plaque et du boitier agencés au même niveau. La protubérance est de quelques millimètres, entre 1 et 5mm par exemple. Ceci permet de rapprocher la surface chaude au plus près du cuir chevelu pour créer le volume à la racine, tout en protégeant ce cuir chevelu du contact de surface chaude par le boitier.According to the invention, at least one of the two longitudinal edges of the plate can be protruding relative to the adjacent edge of the first housing. This is an alternative to the plate and case edges arranged at the same level. The protrusion is a few millimeters, between 1 and 5mm for example. This allows to bring the hot surface closer to the scalp to create volume at the root, while protecting the scalp hot surface contact by the box.

Selon l'invention, le diamètre du mandrin est compris entre 15 et 22 mm, préférentiellement entre 17mm et 20mm, particulièrement égal à sensiblement 19mm. Ceci permet de produire de petites ondulations localisées. Ceci permet de réduire l'encombrement de l'appareil.According to the invention, the diameter of the mandrel is between 15 and 22 mm, preferably between 17 mm and 20 mm, particularly equal to substantially 19 mm. This makes it possible to produce small localized ripples. This reduces the size of the device.

Selon l'invention, l'appareil peut comprendre des moyens de verrouillage de la rotation libre du mandrin. Ceci permet de proposer un appareil double usage : le premier usage avec le mandrin en rotation libre permet de produire du volume ou du décollement de racine, et le deuxième usage avec le mandrin bloqué permet de lisser la mèche.According to the invention, the apparatus may comprise means for locking the free rotation of the mandrel. This makes it possible to propose a dual-use device: the first use with the free-rotating mandrel makes it possible to produce root volume or detachment, and the second use with the locked mandrel makes it possible to smooth the wick.

Selon l'invention, les moyens de verrouillage peuvent comprendre une roue dentée solidaire de l'axe longitudinal (L) du mandrin et une cale solidaire du boitier et destinée à coulisser en translation selon ledit axe longitudinal (L) entre les dents de la roue. Ceci permet à l'utilisateur de bloquer facilement le mouvement en rotation du mandrin.According to the invention, the locking means may comprise a toothed wheel integral with the longitudinal axis (L) of the mandrel and a shim integral with the housing and intended to slide in translation along said longitudinal axis (L) between the teeth of the wheel. . This allows the user to easily block the rotational movement of the mandrel.

Selon l'invention, la largeur du premier boitier au niveau des bords de la première surface de traitement est inférieure à 32mm, voire inférieure à 26mm. Cette largeur est plutôt comprise entre 20mm et 32, voire entre 20mm et 26mm. Ceci permet également de produire de petites ondulations localisées. Ceci permet de réduire l'encombrement de l'appareil.According to the invention, the width of the first housing at the edges of the first treatment surface is less than 32mm, or even less than 26mm. This width is rather between 20mm and 32, or between 20mm and 26mm. This also produces small localized ripples. This reduces the size of the device.

Selon l'invention, le premier boitier peut comprendre deux cylindres latéraux en rotation libre autour de leur axe longitudinal respectif, agencés de chaque côté et adjacents aux bords longitudinaux de la plaque. Ils sont agencés dans la continuité du boitier. Ainsi, lorsque l'utilisateur passe l'appareil le long de la mèche traitée, les cylindres roulent chacun en amont et en aval des surfaces de traitement et évitent d'appliquer une traction prononcée sur la mèche. Le fait que les cylindres soient libres en rotation, et donc facilement « entrainables » par le passage de la mèche de cheveux, évite le frottement de ceux-ci sur le boitier ou sur les côtés de la surface de traitement. De plus, le rayon formé par les cylindres permet de réduire fortement le phénomène de « marquage » des cheveux. Les cylindres sont sensiblement identiques.According to the invention, the first housing may comprise two lateral cylinders in free rotation about their respective longitudinal axis, arranged on each side and adjacent to the longitudinal edges of the plate. They are arranged in the continuity of the case. Thus, when the user passes the device along the treated wick, the rolls each roll upstream and downstream of the treatment surfaces and avoid applying a pronounced traction on the wick. The fact that the cylinders are free to rotate, and therefore easily "drivable" by the passage of the lock of hair, avoids the friction thereof on the housing or on the sides of the treatment surface. In addition, the radius formed by the cylinders can greatly reduce the phenomenon of "marking" of the hair. The cylinders are substantially identical.

Selon l'invention, la première surface de traitement de cheveux peut être destinée à être chauffée par un deuxième moyen de chauffage. Ceci permet une mise en forme améliorée par plus de chauffe des cheveux.According to the invention, the first hair treatment surface may be intended to be heated by a second heating means. This allows improved shaping by more hair heating.

L'invention concerne également un procédé d'utilisation de l'appareil selon l'invention comportant les étapes suivantes : a) Appliquer l'appareil à la racine d'une mèche de cheveux et le pincer statiquement pendant plusieurs secondes au plus proche de la racine, b) ensuite faire pivoter l'appareil autour de son axe longitudinal (L) d'environ un quart de tour vers le bas, c) et ensuite glisser l'appareil le long de la mèche jusqu'à son extrémité.The invention also relates to a method of using the apparatus according to the invention comprising the following steps: a) Apply the apparatus to the root of a lock of hair and pinch it statically for several seconds to the nearest of the root, b) then rotate the apparatus about its longitudinal axis (L) about a quarter of a turn downwards, c) and then slide the apparatus along the wick to its end.

Exposé détaillé de l'invention :Detailed description of the invention:

Comme illustré en figures 1, 2, 3, 4, 6 et 8, l'invention concerne un appareil de coiffure chauffant 1 pour la mise en forme de cheveux comprenant un premier bras ou boitier 10 définissant un axe longitudinal L et un deuxième bras ou boitier 20 d'axe longitudinal L' disposés en regard l'un de l'autre et connectés de façon pivotante par une charnière 30 pour définir une position ouverte et fermée de l'appareil. Le premier bras 10 comprend une partie définissant une première surface de traitement intérieure de forme concave 12 qui est une plaque. La plaque est mobile par rapport à l'autre bras uniquement par pivotement autour d'un axe orthogonal aux axes longitudinaux des deux bras. Un deuxième moyen de chauffage 13 est disposé pour chauffer au moins la première plaque de traitement 12. Le deuxième bras 20 comprend au moins une partie définissant une deuxième surface de traitement 22: il s'agit d'un mandrin longitudinal 22 formant la deuxième surface de traitement de cheveux destinée à être chauffée par un premier moyen électrique de chauffage 23 ; le mandrin est destiné à être en rotation libre autour de son axe longitudinal ; et sensiblement de même rayon que la plaque. Par rotation libre on entend que le mandrin n'est pas motorisé et n'est pas bloqué immobile. La deuxième surface de traitement 22 est destinée à venir en contact avec la première surface de traitement 12 pour accueillir les cheveux en position fermée. La plaque concave est destinée à recouvrir le mandrin en position fermée selon un angle de recouvrement (α) compris entre 160° et 190°. Plus précisément, l'angle de recouvrement (α) peut être compris entre 170° et 185°, et il est illustré ici égal à environ 180°. Le principe est que la plaque concave recouvre d'environ un demi cercle le mandrin. Au moins un des deux bords longitudinaux de la plaque 12 présente une épaisseur (e) comprise entre 2 et 6mm. On appelle bords longitudinaux, comme illustré en figures 3 à 8 les bords formés par la plaque 12 dans l'axe longitudinal de celle-ci, c'est-à-dire un axe parallèle ou confondu avec l'axe L'. L'axe longitudinal de la plaque 12 est parallèle à l'axe de symétrie et de rotation du mandrin en position fermée de l'appareil. Au moins un des deux bords 12', 12" longitudinaux de la plaque 12 peut être au même niveau que le bord adjacent 10', 10" du premier boitier 10. Dans le cas d'une plaque à section demi circulaire, les bords sont coplanaires dans P comme illustré en figure 4. Alternativement, au moins un des deux bords 12', 12" longitudinaux de la plaque 12 peut être protubérant par rapport au bord adjacent 10', 10" du premier boitier 10. Le diamètre du mandrin 22 est compris entre 15 et 22 mm, préférentiellement égal à 19mm. La largeur La du premier boitier au niveau des bords de la première surface de traitement 12 est inférieure à 32mm, voire inférieure à 26mm, préférentiellement comprise entre 20 et 26mm.As illustrated in Figures 1, 2, 3 , 4 , 6 and 8 the invention relates to a hair styling apparatus 1 for shaping hair comprising a first arm or casing 10 defining a longitudinal axis L and a second arm or casing 20 of longitudinal axis L 'disposed facing one of the other and pivotally connected by a hinge 30 to define an open and closed position of the apparatus. The first arm 10 includes a portion defining a concave first interior treatment surface 12 which is a plate. The plate is movable relative to the other arm only by pivoting about an axis orthogonal to the longitudinal axes of the two arms. A second heating means 13 is arranged for heating at least the first treatment plate 12. The second arm 20 comprises at least one part defining a second treatment surface 22: it is a longitudinal mandrel 22 forming the second surface hair treatment apparatus for heating by first electric heating means 23; the mandrel is intended to be freely rotatable about its longitudinal axis; and of substantially the same radius as the plate. By free rotation is meant that the mandrel is not motorized and is not locked motionless. The second treatment surface 22 is intended to come into contact with the first treatment surface 12 to accommodate the hair in the closed position. The concave plate is intended to cover the mandrel in the closed position at a covering angle (α) of between 160 ° and 190 °. More precisely, the angle of overlap (α) can be between 170 ° and 185 °, and is illustrated here equal to about 180 °. The principle is that the concave plate covers the mandrel by about a half circle. At least one of the two longitudinal edges of the plate 12 has a thickness (e) of between 2 and 6 mm. Longitudinal edges are called, as illustrated in Figures 3 to 8 the edges formed by the plate 12 in the longitudinal axis thereof, that is to say an axis parallel or coincident with the axis L '. The longitudinal axis of the plate 12 is parallel to the axis of symmetry and rotation of the mandrel in the closed position of the apparatus. At least one of the two longitudinal edges 12 ', 12 "of the plate 12 may be at the same level as the adjacent edge 10', 10" of the first housing 10. In the case of a half-circular section plate, the edges are coplanar in P as illustrated in figure 4 . Alternatively, at least one of the two edges 12 ', 12 "of the longitudinal plate 12 may be protruding relative to the adjacent edge 10', 10" of the first housing 10. The diameter of the mandrel 22 is between 15 and 22 mm, preferably equal to 19mm. The width La of the first housing at the edges of the first treatment surface 12 is less than 32 mm, or even less than 26 mm, preferably between 20 and 26 mm.

Des moyens de verrouillage 26, 27 de la rotation libre du mandrin 22 peuvent être prévus comme illustrés en figure 8 dans un mode de réalisation exemplatif: ils comprennent une roue dentée 26 solidaire de l'axe longitudinal du mandrin 22 et une cale 27 solidaire du boitier 10 et coulissable en translation selon l'axe longitudinal (L) du mandrin destinée à coulisser entre les dents de la roue 26.La cale est attachée au bouton 34 présent sur le boitier. D'autres systèmes de blocage alternatifs peuvent être prévus : un mode de réalisation utilisant un barillet et une cale selon l'axe du mandrin rentrant dans une des cavités d'un disque en regard, ou bien une réalisation par engrenages avec une roue dentée solidaire du bouton de commande qui peut rentrer dans la roue dentée solidaire du mandrin pour le bloquer.Locking means 26, 27 of the free rotation of mandrel 22 may be provided as illustrated in FIG. figure 8 in an exemplary embodiment: they comprise a toothed wheel 26 integral with the longitudinal axis of the mandrel 22 and a shim 27 integral with the housing 10 and slidable in translation along the longitudinal axis (L) of the mandrel intended to slide between the teeth 26. The shim is attached to the button 34 present on the case. Other alternative locking systems may be provided: an embodiment using a barrel and a wedge along the axis of the mandrel entering into one of the cavities of a disc facing, or a gear embodiment with a solid toothed wheel the control button that can fit into the toothed wheel integral with the mandrel to block it.

La plaque courbée 12 pourra être chauffée par un deuxième moyen de chauffage 13. Le deuxième moyen de chauffage 13, tout comme le premier moyen de chauffage 23, peut être une résistance électrique, notamment une résistance du type thermistance CTP. Une telle résistance présente notamment l'avantage d'un faible encombrement pour un bon rendement thermique de chauffe; de plus elle présente des propriétés d'autorégulation thermique. Comme illustré en figures 6 et 7 la plaque 12 en U ou en demi-cercle comprend une base tangentielle à la courbe et formant une pièce symétrique selon un plan contenant l'axe L'. Cette base présente une cavité pour recevoir l'élément chauffant 13. Dans une seconde variante de réalisation, l'élément chauffant peut être une résistance céramique ou encore être constitué d'un film souple résistant électriquement. La surface de traitement peut être en métal, par exemple en aluminium, ou en tout autre matériau qui présente un bon compromis entre la conductibilité thermique et le coût. Une carte imprimée (non illustrée) est maintenue par le capot et permet le contrôle en chauffe de l'appareil. Un afficheur 31, par exemple numérique, affiche la température commandée de chauffe des plaques en fonctionnement. Un interrupteur 32 est prévu pour commander la température de chauffe. Des voyants 33 sont prévus pour avertir que la phase de chauffe est terminée et indiquer que l'appareil est prêt à être utilisé.The curved plate 12 may be heated by a second heating means 13. The second heating means 13, just like the first heating means 23, may be an electrical resistance, in particular a PTC thermistor type resistor. Such a resistance has the particular advantage of a small footprint for a good thermal heating efficiency; in addition, it has thermal self-regulation properties. As illustrated in Figures 6 and 7 the plate 12 in U or in a semicircle comprises a base tangential to the curve and forming a symmetrical part in a plane containing the axis L '. This base has a cavity for receiving the heating element 13. In a second variant embodiment, the heating element may be a ceramic resistor or may consist of an electrically resistant flexible film. The treatment surface may be metal, for example aluminum, or any other material that has a good compromise between thermal conductivity and cost. A printed circuit board (not shown) is held by the hood and allows control when the appliance is heated. A display 31, for example digital, displays the controlled temperature of heating plates in operation. A switch 32 is provided to control the heating temperature. Indicators 33 are provided to warn that the heating phase is over and indicate that the device is ready for use.

Une alternative à l'invention est illustrée en figures 5 et 7. Il s'agit de l'appareil selon l'invention modifié en ce qu'il présente deux cylindres 14, 15 agencés de chaque côté de l'espace de traitement défini par la zone de pincement des première et deuxième surfaces. Les cylindres sont attachés au premier boitier 10. Les cylindres sont mobiles en rotation autour de leur axe longitudinal 014 ; 015. Leur axe longitudinal est parallèle à l'axe longitudinal du bras ou boitier 10 les supportant. Les cylindres peuvent être des cylindres de révolution. Uniquement deux cylindres 14, 15 mobiles en rotation sont prévus sur le premier bras 10, sans que d'autres cylindres mobiles soient agencés en regard sur le deuxième bras: le principe est que la mèche de cheveux est en contact avec un cylindre à la fois qui roule le long de la mèche. La mèche n'est pas agencée en contact entre deux cylindres pinçant la mèche, en mouvement et en contact.An alternative to the invention is illustrated in figures 5 and 7 . This is the apparatus according to the invention modified in that it has two cylinders 14, 15 arranged on each side of the treatment space defined by the nip area of the first and second surfaces. The cylinders are attached to the first housing 10. The cylinders are rotatable about their longitudinal axis 014; 015. Their longitudinal axis is parallel to the longitudinal axis of the arm or housing 10 supporting them. The cylinders can be cylinders of revolution. Only two cylinders 14, 15 movable in rotation are provided on the first arm 10, without other movable cylinders are arranged opposite on the second arm: the principle is that the lock of hair is in contact with a cylinder at a time rolling along the wick. The wick is not arranged in contact between two cylinders pinching the wick, moving and in contact.

Les deux cylindres 14, 15 sont montés mobiles en rotation libre autour de leur axe longitudinal respectif Δ14 ; Δ15 et respectivement sur deux extensions 18 et 19 du bras 10. Ils tournent ainsi selon la direction et la vitesse de mouvement de l'appareil le long de la mèche. Selon l'invention, les axes longitudinaux des deux cylindres peuvent être parallèles. Ceci permet d'appliquer de façon symétrique une traction diminuée de chaque côté de la surface de travail des cheveux. Les deux cylindres 14, 15 sont agencés directement adjacents à la surface de traitement 12. Ils sont dans la continuité de la surface de traitement. Par « directement adjacents » on entend que chaque cylindre est proche de chaque bord de la surface de traitement sans qu'une autre pièce ne soit interposée entre le bord et le cylindre. Ils sont séparés par un petit espacement nécessité par la construction de l'appareil. Comme visible en figure chacun des axes (Δ14 ; Δ15) des deux cylindres 14, 15 et chacun des deux bords 12', 12" de la surface de traitement adjacents aux cylindres 14, 15 sont sensiblement coplanaires dans le plan P. Ceci signifie que, en plus d'être proches, ils sont situés sensiblement au même niveau de sorte à ne pas créer de modification de la mise en forme par la simple adjonction des petits cylindres. Les cylindres sont agencés de chaque côté de la première surface de traitement 12. Comme illustré en figure 7, le deuxième boitier 20 présente ses bords longitudinaux 20',20" agencés de chaque côté de la deuxième surface de traitement 22 et en regard avec les cylindres 14, 15 en position fermée. Les cylindres 14, 15 ont un diamètre compris entre 3 et 6mm, préférentiellement entre 4 et 5mm. Ils peuvent être fabriqués en métal, par exemple en aluminium, ou en plastique, par exemple en polymère type silicone, EPDM (éthylène-propylène-diène monomère), en PPS (Polypropylène)... Tout matériau résistant à une température au dessus de 50°C environ convient. La forme et le matériau sont choisis pour rendre la surface du cylindre la plus lisse possible. Les cylindres peuvent être recouverts d'un matériau poreux imbibé d'agent fluide, dans ce cas, le cylindre est une tige entourée d'un rouleau creux de matériau poreux. L'agent fluide peut être de l'eau, ou un fluide contenant un cosmétique à fonction de fixation, de coloration, de protection thermique... selon le sens de passage de l'appareil sur la mèche, le fluide peut être différent dans chaque rouleau de matériau poreux. Les cylindres peuvent être démontables, nettoyables, voire interchangeables. Ceci permet une application de cosmétique en même temps que le lissage de la mèche.The two cylinders 14, 15 are movably mounted in free rotation around their respective longitudinal axis Δ14; Δ15 and respectively on two extensions 18 and 19 of the arm 10. They thus rotate according to the direction and speed of movement of the device along the wick. According to the invention, the longitudinal axes of the two cylinders can be parallel. This makes it possible to symmetrically apply a decreased traction on each side of the working surface of the hair. The two cylinders 14, 15 are arranged directly adjacent to the treatment surface 12. They are in continuity with the treatment surface. By "directly adjacent" is meant that each cylinder is close to each edge of the treatment surface without another piece being interposed between the edge and the cylinder. They are separated by a small spacing required by the construction of the apparatus. As can be seen in the figure, each of the axes (Δ14; Δ15) of the two cylinders 14, 15 and each of the two edges 12 ', 12 "of the treatment surface adjacent to the rolls 14, 15 are substantially coplanar in the plane P. This means that , in addition to being close, they are located substantially at same level so as not to create a modification of the formatting by the simple addition of small cylinders. The cylinders are arranged on each side of the first treatment surface 12. As illustrated in FIG. figure 7 , the second housing 20 has its longitudinal edges 20 ', 20 "arranged on each side of the second treatment surface 22 and facing the cylinders 14, 15 in the closed position.The rolls 14, 15 have a diameter of between 3 and 6 mm, preferably between 4 and 5 mm, they may be made of metal, for example aluminum, or plastic, for example silicone-type polymer, EPDM (ethylene-propylene-diene monomer), PPS (polypropylene), etc. material resistant to a temperature above about 50 ° C. The shape and material are chosen to make the surface of the roll as smooth as possible.The rolls may be covered with a porous material impregnated with a fluid agent, in which case the In this case, the cylinder is a rod surrounded by a hollow roll of porous material The fluid agent may be water, or a fluid containing a cosmetic with a function of fixing, coloring, thermal protection ... sense of When passing the device over the wick, the fluid may be different in each roll of porous material. The cylinders can be dismountable, cleanable or even interchangeable. This allows a cosmetic application at the same time as the smoothing of the wick.

Description en fonctionnement :Description in operation:

Ainsi, en fonctionnement, l'utilisateur commence par mettre sous tension l'appareil qui commande alors la mise en température de la ou des surfaces de traitement. Un voyant lumineux 33 peut avertir que la phase de chauffe est terminée. Pour un effet volume à la racine, au préalable, l'utilisateur aura déverrouillé si nécessaire le mandrin pour le placer en rotation libre. La figure 9 décrit les 4 étapes du procédé pour former du volume à la racine. L'utilisateur saisit alors une mèche de cheveux et introduit la mèche, par exemple à la racine, entre les surfaces de traitement 12 et 22 et ferme l'appareil et pince statiquement pendant plusieurs secondes la mèche (étape n°1). Dans cette position, le boitier comportant la plaque concave est agencé en haut et le boitier comportant le mandrin est agencé vers le bas. Ensuite l'utilisateur peut faire pivoter l'appareil autour de son axe longitudinal (L) d'environ un quart de tour vers le bas (étape n°2) sans translater l'appareil, et ensuite glisse l'appareil le long de la mèche jusqu'à son extrémité et à la libération de la mèche (étape n°3). Le résultat sur les cheveux est illustré (étape n°4). Lors de tests, les inventeurs ont constaté que ce volume à la racine peut tenir pendant 1 ou 2 jours, sans devoir répéter le procédé chaque matin.Thus, in operation, the user begins by turning on the device which then controls the temperature of the treatment surface or surfaces. An indicator light 33 can warn that the heating phase is over. For a volume effect at the root, beforehand, the user will have unlocked if necessary the mandrel to place it in free rotation. The figure 9 describes the 4 steps of the process to form volume at the root. The user then grabs a lock of hair and introduces the wick, for example at the root, between the treatment surfaces 12 and 22 and closes the apparatus and statically pinches for several seconds the wick (step No. 1). In this position, the case comprising the concave plate is arranged at the top and the housing comprising the mandrel is arranged downwards. Then the user can rotate the device around its axis longitudinally (L) of about a quarter turn down (step 2) without translating the apparatus, and then slide the apparatus along the wick to its end and the release of the wick ( step 3). The result on the hair is illustrated (step # 4). In tests, the inventors have found that this volume at the root can hold for 1 or 2 days, without having to repeat the process each morning.

Bien entendu, l'invention n'est nullement limitée aux modes de réalisation décrits et illustrés qui n'ont été donnés qu'à titre d'exemple. Des modifications restent possibles, notamment du point de vue de la constitution des divers éléments ou par substitution d'équivalents techniques, sans sortir pour autant du domaine de protection de l'invention telle que revendiquée.Of course, the invention is not limited to the described and illustrated embodiments which have been given by way of example. Modifications are possible, in particular from the point of view of the constitution of the various elements or by substitution of technical equivalents, without departing from the scope of protection of the invention as claimed.
