Description

APPAREIL DE COIFFURE  HAIRSTYLING APPARATUS
POUR FORMER DES BOUCLES DE TAILLES DIFFERENTES Domaine technique de l'invention  TO FORM BUCKLES OF DIFFERENT SIZES Technical field of the invention
La présente invention concerne un appareil de coiffure pouvant utiliser de la vapeur et destiné à la mise en forme par contact avec les cheveux, notamment destiné au lissage mais aussi au bouclage des cheveux d'une personne. The present invention relates to a hairstyling device that can use steam and intended for shaping by contact with the hair, in particular for smoothing but also for wrapping a person's hair.
Etat de la technique antérieure : State of the prior art:
On connaît traditionnellement deux types d'appareils de coiffure différents permettant le lissage ou le bouclage : les bigoudis chauffants ou non, le lisseur ou pince à lisser et le boudeur ou curler ou pince à boucler. Two types of different hairstyling devices are traditionally known for smoothing or looping: hair curlers or not, straightener or straightener and looper or curler or loop pliers.
Les appareils du type pinces à lisser ou à boucler comportent généralement deux mâchoires pivotantes l'une par rapport à l'autre autour d'un axe commun, et comprenant chacune une extrémité supportant une surface de traitement, au moins l'une des surfaces de traitement étant chauffée, l'autre étant prévue pour amener les cheveux en contact avec la première, notamment en passant d'une position d'ouverture des mâchoires permettant l'insertion des cheveux à une position de fermeture pour leur mise en contact avec la partie chauffante.  The devices of the type pliers to smooth or loop usually comprise two jaws pivoting relative to each other about a common axis, and each comprising an end supporting a treatment surface, at least one of the surfaces of treatment being heated, the other being provided to bring the hair in contact with the first, in particular by passing from an opening position of the jaws allowing the insertion of the hair to a closed position for their contact with the part heating.
Le lisseur présente sur une première extrémité de ses mâchoires deux surfaces chauffées planes identiques et venant pincer les cheveux. De plus, l'autre extrémité des mâchoires forme deux poignées faisant office de zone de préhension et permettant de passer de la position d'ouverture à celle de fermeture. Le passage se fait manuellement en pressant les deux poignées articulées de l'appareil l'une vers l'autre pour amener les surfaces de traitement au contact des cheveux. Le lissage d'une mèche de cheveux s'effectue en déplaçant l'appareil le long de cette mèche, de la racine vers la pointe selon une translation droite de l'appareil fermé. The straightener has on one end of its jaws two identical flat heated surfaces and gripping the hair. In addition, the other end of the jaws form two handles acting as a gripping area and to move from the open position to the closing position. The passage is done manually by pressing the two articulated handles of the device towards one another to bring the treatment surfaces in contact with the hair. Smoothing a lock of hair is done by moving the device along this wick, from the root to the tip in a straight translation of the closed device.
Le boudeur a des surfaces formées par un mandrin cylindrique chauffant avec une tuile venant pincer l'extrémité de la mèche en pivotement sur le mandrin avant d'enrouler la mèche complète autour du mandrin. Le bouclage d'une mèche de cheveux se fait en enroulant au moins partiellement la mèche autour de la ou des surfaces de traitement et en appliquant de la chaleur pour fixer la boucle principalement en statique. II est prévu dans chacun de ces deux appareils d'utiliser additionnellement de la vapeur projetée sur les cheveux. Ceci permet d'améliorer la mise en forme des cheveux, d'allonger la mise en forme des cheveux, de garder l'humidité dans les cheveux, de soigner les cheveux ou d'aider à la pénétration d'actifs cosmétiques dans les cheveux. The looper has surfaces formed by a cylindrical heating mandrel with a tile pinching the end of the wick pivotably on the mandrel prior to winding the complete wick around the mandrel. The closure of a strand of hair is made by at least partially winding the wick around the treatment surface (s) and applying heat to fix the loop mainly in static. It is provided in each of these two devices to additionally use steam sprayed on the hair. This makes it possible to improve the shaping of the hair, to lengthen the shaping of the hair, to keep the moisture in the hair, to heal the hair or to help the penetration of cosmetic active ingredients into the hair.
Il est connu des appareils à lisser fonctionnant à la vapeur comme ceux décrits par la demanderesse dans WO2009077672 et dans EP2591698. Le lisseur du deuxième document cité est illustré en figure 1 . Il présente une pince à lisser comportant deux plaques planes de lissage identiques et en regard l'une de l'autre et des orifices de sortie de vapeur. Le lisseur vapeur tel que décrit dans EP2591698 et illustré dans la présente demande est considéré en figure 1 comme l'art antérieur le plus proche. Cet appareil actuellement commercialisé donne toute satisfaction en termes de lissage et est capable de produire un débit de vapeur suffisant pour soigner hautement la fibre capillaire. Néanmoins, pour produire un excellent lissage et un débit de vapeur conséquent, cet appareil contient de nombreux éléments internes qui ont une configuration optimisée techniquement mais qui occupent un encombrement assez grand par rapport à une pince à lisser classique. En effet, la mâchoire qui produit de la vapeur contient une chambre de vaporisation. Ainsi les deux boîtiers ou encore les deux coques recevant les plaques et la chambre de vaporisation présentent chacun un capot externe qui, en section transversale, a une largeur ou plus grande largeur identique. Les deux capots dessinent cependant une ligne externe asymétrique et relativement plane notamment au niveau de la fonction vapeur, c'est-à-dire au niveau des orifices de vapeur et du déflecteur en regard des orifices. Steam straighteners are known, such as those described by the applicant in WO2009077672 and in EP2591698. The straightener of the second document cited is illustrated in FIG. It has a smoothing pliers comprising two identical planar smoothing plates and facing one another and the steam outlet orifices. The vapor straightener as described in EP2591698 and illustrated in the present application is considered in FIG. 1 as the closest prior art. This currently marketed device is satisfactory in terms of smoothing and is capable of producing a steam flow sufficient to highly treat the hair fiber. Nevertheless, to produce an excellent smoothing and a significant steam flow, this device contains many internal elements that have a technically optimized configuration but occupy a large enough space compared to a conventional straightener. Indeed, the jaw that produces steam contains a vaporization chamber. Thus the two housings or the two shells receiving the plates and the vaporization chamber each have an outer cover which, in cross section, has a width or greater identical width. The two covers, however, draw an asymmetrical external line and relatively flat especially at the steam function, that is to say at the steam ports and the deflector facing the orifices.
Ainsi, si l'utilisateur veut utiliser cet appareil pour former des boucles en entourant la mèche autour d'un capot ou des deux capots, il n'arrivera pas à former une boucle bien ronde ni à former une boucle bien régulière ni à glisser de façon fluide et régulière pour défaire la boucle une fois formée. Thus, if the user wants to use this device to form loops by surrounding the wick around a hood or two covers, it will not be able to form a well round loop or to form a very regular loop or slip in a fluid and regular way to undo the loop once formed.

Ces objectifs sont atteints avec, selon un premier aspect de l'invention, un appareil de coiffure pour le bouclage et le lissage de cheveux comprenant une première et une deuxième mâchoires allongées et mobiles en pivotement l'une par rapport à l'autre, la première mâchoire présentant un premier boîtier portant une première surface plane de traitement interne et la deuxième mâchoire présentant un deuxième boîtier portant une deuxième surface plane de traitement interne, les surfaces internes étant destinées à pincer une mèche de cheveux, au moins un élément chauffant destiné à chauffer au moins une surface de traitement interne. Dans cet appareil, la plus grande largeur 11 du premier boîtier est inférieure ou égale à 90% de la plus grande largeur 12 du deuxième boîtier. Cette caractéristique, contraire à tout cahier des charges classique d'un lisseur qui se doit de présenter des largeurs de boîtiers identiques, permet de fournir des boîtiers différents et donc permet de produire des boucles de tailles différentes autour d'un boîtier ou de l'ensemble des deux boîtiers en position fermée, Ceci tout en gardant un appareil simple et peu encombrant. On considérera la plus grande largeur comme référence de rapport dimensionnel entre les deux boîtiers. De plus dans cet appareil, au moins un du premier boîtier ou du second boîtier est asymétrique par rapport au plan médian en coupe longitudinale respectivement dudit premier boîtier ou dudit second boîtier. Cette caractéristique permet d'obtenir des boucles dont le rayon de courbure n'est pas constant pour un effet plus naturel. Selon l'invention, la deuxième mâchoire comprend des moyens de sortie de vapeur orientés vers le premier boîtier et adjacents à la deuxième surface de traitement interne. Ceci permet de fournir le traitement vapeur avant le traitement lissage dans l'ordre préconisé de passage du lisseur sur la mèche. Les éléments techniques permettant de produire et extraire la vapeur sont enfermés dans la mâchoire la plus encombrante, à savoir la mâchoire la plus large. Les moyens de production de la vapeur comprennent au moins un réservoir de fluide en communication de fluide avec une chambre de vaporisation, la chambre de vaporisation pouvant être chauffée par un moyen de chauffage destiné à chauffer aussi la surface de traitement ou bien par un moyen de chauffage dédié uniquement à la chambre de vaporisation. These objectives are achieved with, according to a first aspect of the invention, a hair styling device for looping and straightening hair comprising a first and a second jaw elongated and pivotally movable relative to each other, the first jaw having a first housing having a first internal treatment planar surface and the second jaw having a second housing carrying a second inner planar surface of treatment, the inner surfaces being for gripping a lock of hair, at least one heating element for heating at least one internal treatment surface. In this apparatus, the largest width 11 of the first housing is less than or equal to 90% of the largest width 12 of the second housing. This characteristic, contrary to any conventional specification of a straightener which must have identical casing widths, makes it possible to provide different casings and thus makes it possible to produce loops of different sizes around a casing or the casing. together the two housings in the closed position, This while keeping a simple device and compact. The largest width will be considered as the dimensional ratio reference between the two housings. In addition in this apparatus, at least one of the first housing or the second housing is asymmetrical with respect to the longitudinal sectional mid-plane respectively of said first housing or said second housing. This characteristic makes it possible to obtain loops whose radius of curvature is not constant for a more natural effect. According to the invention, the second jaw comprises steam outlet means oriented towards the first housing and adjacent to the second internal treatment surface. This makes it possible to provide the steam treatment before the smoothing treatment in the preferred order of passage of the straightener on the wick. The technical elements to produce and extract the steam are enclosed in the largest jaw, namely the largest jaw. The steam generating means comprises at least one fluid reservoir in fluid communication with a vaporization chamber, the vaporization chamber being heated by a heating means for also heating the treatment surface or by means of dedicated heating only to the steam chamber.
Plus particulièrement selon l'invention, la plus grande largeur 11 du premier boîtier est comprise entre 75% et 85% de la plus grande largeur 12 du deuxième boîtier, préférentiellement égale à 80%. Ceci permet à chaque boîtier de recevoir tous les éléments techniques intérieurs tout en limitant l'encombrement externe global des deux capots ou deux coques recevant la partie de traitement des cheveux. Selon l'invention, en position fermée des mâchoires, le plan médian P1 en coupe longitudinale du premier boîtier est parallèle à et distinct du plan médian P2 en coupe longitudinale du deuxième boîtier. Ceci signifie qu'en coupe transversale orthogonale à l'axe longitudinal du lisseur, la section ne présente pas de symétrie orthogonale par rapport au plan de lissage Pl. Le plan de lissage PI est défini en ce qu'il contient la zone de lissage plane formée par les deux surfaces planes de traitement l'une contre l'autre en position fermée de l'appareil. Chacun des deux boîtiers est agencé de chaque côté du plan de lissage. Ainsi, au niveau de la zone de traitement, le premier boîtier est décalé par rapport au deuxième boîtier. Cette dissymétrie ou ce décalage permet de fournir un appareil dont l'usage se fera intuitivement pour l'utilisateur selon un sens particulier. Cet agencement guide intuitivement l'utilisateur vers le mode d'utilisation le plus efficace. Plus particulièrement selon l'invention, la distance entre lesdits deux plans médians (P1 , P2) est comprise entre 5% et 20% de la valeur de la plus grande largeur 12 du deuxième boîtier, préférentiel lement égale à 10%. Ce décalage est prononcé suffisamment pour guider ergonomiquement l'utilisateur. Selon l'invention, en position fermée des mâchoires, un des deux bords longitudinaux du premier boîtier est à l'aplomb du bord longitudinal du deuxième boîtier agencé du même côté du deuxième boîtier. Ceci signifie qu'en position fermée, deux bords du même côté de l'appareil sont l'un en regard de l'autre (comme habituellement pour un lisseur) et, a fortiori, les deux bords de l'autre côté du boîtier seront décalés l'un par rapport à l'autre. Du côté où les bords sont à l'aplomb, la courbe formée par le contour des deux coques ou boîtiers sera relativement symétrique par rapport au plan de lissage Pl. Le plan de lissage PI est le plan contenant la zone de lissage formée par les deux surfaces en contact l'une avec l'autre. Ces deux bords à l'aplomb permettent de former des boucles de grande dimension en enroulant la mèche autour des deux boîtiers en position fermée de l'appareil. Ces deux bords à l'aplomb l'un de l'autre permettent de former une boucle lâche et bien ronde, c'est— à-dire régulière et sans marque non souhaitée avec un appareil relativement compact par rapport à la taille de la boucle obtenue. Selon l'invention, les surfaces de traitement internes sont planes, identiques et sont en regard l'une de l'autre en position fermée, sont agencées dans leur boîtier respectif et adjacentes auxdits bords en aplomb. On entend par « adjacentes » le plus proche ou voisin possible en prenant en considération les contraintes de fabrication, et en prenant en compte la présence éventuelle d'une barrette entre le boîtier et la surface de traitement. Ceci signifie que le traitement de lissage se fait du côté des bords à l'aplomb. En usage sur la mèche à traiter, ces bords sont à agencer côté cuir chevelu pour permettre aux cheveux, parmi les différentes combinaisons de traitements fournis par l'appareil (notamment le lissage, la vapeur, voire le peignage ou le brossage), d'être soumis en dernier lieu au traitement de lissage et assurer un fini de la coiffure parfait. More particularly according to the invention, the largest width 11 of the first housing is between 75% and 85% of the largest width 12 of the second housing, preferably equal to 80%. This allows each housing to receive all the interior technical elements while limiting the overall external dimensions of the two covers or two shells receiving the hair treatment part. According to the invention, in the closed position of the jaws, the median plane P1 in longitudinal section of the first housing is parallel to and distinct from the median plane P2 in longitudinal section of the second housing. This means that in cross-section orthogonal to the longitudinal axis of the straightener, the section does not have orthogonal symmetry with respect to the smoothing plane P1. The smoothing plane P1 is defined in that it contains the planar smoothing zone. formed by the two flat treatment surfaces against each other in the closed position of the apparatus. Each of the two housings is arranged on each side of the plane of smoothing. Thus, at the level of the treatment zone, the first housing is offset relative to the second housing. This asymmetry or this offset provides a device whose use will be intuitively for the user in a particular sense. This arrangement intuitively guides the user to the most efficient mode of use. More particularly according to the invention, the distance between said two median planes (P1, P2) is between 5% and 20% of the value of the largest width 12 of the second housing, preferably equal to 10%. This offset is pronounced sufficiently to guide the user ergonomically. According to the invention, in the closed position of the jaws, one of the two longitudinal edges of the first housing is in line with the longitudinal edge of the second housing arranged on the same side of the second housing. This means that in the closed position, two edges on the same side of the device are facing each other (as usually for a straightener) and, a fortiori, the two edges on the other side of the housing will be offset with respect to each other. On the side where the edges are plumb, the curve formed by the contour of the two shells or boxes will be relatively symmetrical with respect to the plane of smoothing Pl. The plane of smoothing PI is the plane containing the smoothing zone formed by the two surfaces in contact with each other. These two plumb edges make it possible to form large loops by winding the wick around the two housings in the closed position of the apparatus. These two edges plumb to each other make it possible to form a loose and round loop, that is to say regular and without unwanted mark with a relatively compact device compared to the size of the loop. obtained. According to the invention, the internal processing surfaces are planar, identical and are facing each other in the closed position, are arranged in their respective housing and adjacent to said plumbed edges. The term "adjacent" closest possible neighbor or taking into account the constraints of manufacture, and taking into account the possible presence of a bar between the housing and the treatment surface. This means that the smoothing treatment is on the side of the edges plumb. In use on the wick to be treated, these edges are arranged on the scalp side to allow the hair, among the various combinations of treatments provided by the device (including smoothing, steaming, even combing or brushing), to be subjected lastly to the treatment of smoothing and to ensure a finish of the perfect hairstyle.
Plus particulièrement selon l'invention, chacun desdits deux bords longitudinaux est muni d'au moins une barrette protubérante vers l'intérieur du boîtier et en même matériau que celui desdits boîtiers. Cette barrette est protubérante par rapport au contour du boîtier et est orientée vers l'intérieur du boîtier. Cette barrette forme idéalement deux surfaces avec un angle droit (et non un chanfrein) et dont une des deux surfaces est parallèle à la surface de traitement ou surface de la plaque de lissage adjacente. Cette barrette permet, lorsque l'appareil est fermé de recevoir la mèche en tension, de la soumettre à un cisaillement et la courber plus facilement. Cet effet appelé « bolduc » est à comparer avec l'effet d'une lame de ciseau passée en glissant sur un ruban bolduc pour y former des boucles. Les barrettes sont identiques et agencées en même lieu sur les mâchoires pour produire l'effet dit « bolduc » identique selon l'inclinaison du lisseur vers le haut comme vers le bas. La barrette a un design spécifique et un état de surface permettant aux cheveux d'avoir une force de frottement sur la barrette supérieure par rapport à la force de frottement sur la surface externe des mâchoires. L'état de surface peut être un revêtement rugueux. More particularly according to the invention, each of said two longitudinal edges is provided with at least one protruding bar towards the inside of the housing and of the same material as that of said housings. This bar is protruding relative to the contour of the housing and is oriented towards the inside of the housing. This bar ideally forms two surfaces with a right angle (and not a chamfer) and one of which is parallel to the treatment surface or surface of the adjacent smoothing plate. This bar allows, when the device is closed to receive the wick in tension, to submit to a shear and bend more easily. This effect called "bolduc" is to be compared with the effect of a chisel blade passed by sliding on a ribbon ribbon to form loops. The bars are identical and arranged in the same place on the jaws to produce the effect called "bolduc" identical according to the inclination of the straightener upwards and downwards. The bar has a specific design and surface condition allowing the hair to have a frictional force on the upper bar relative to the frictional force on the outer surface of the jaws. The surface condition can be a rough coating.
Selon l'invention, la largeur de chaque surface de traitement interne est comprise entre 40% et 60% de la plus grande largeur 11 du premier boîtier, préférentiellement entre 40% et 50%, préférentiellement égale à sensiblement 45%. Sensiblement la moitié de la largeur des boîtiers est occupée pour produire l'étape de traitement principale à savoir l'étape de lissage nécessaire pour lisser la mèche qui sera peut être ensuite bouclée selon le choix de l'utilisateur. According to the invention, the width of each internal processing surface is between 40% and 60% of the largest width 11 of the first housing, preferably between 40% and 50%, preferably equal to substantially 45%. Substantially half the width of the housings is occupied to produce the main processing step namely the smoothing step necessary to smooth the wick that may be then looped according to the choice of the user.
Plus particulièrement selon l'invention, le premier boîtier présente un déflecteur formé dans son contour intérieur et agencé en position fermée sensiblement en face des moyens de sortie de vapeur du deuxième boîtier. Ce déflecteur a plusieurs fonctions : protéger le cuir chevelu de tout jet de vapeur qui pourrait le brûler, réfléchir la vapeur vers le cheveu qui sera traversé deux fois et sera ainsi mieux traité. L'angle et l'agencement du déflecteur est tel que sa dimension est minimisée au mieux par rapport à l'art antérieur le plus proche tout en gardant ses fonctionnalités. More particularly according to the invention, the first housing has a deflector formed in its inner contour and arranged in closed position substantially opposite the steam outlet means of the second housing. This deflector has several functions: protect the scalp from any jet of steam that could burn it, reflect the vapor to the hair that will be crossed twice and will be better treated. The angle and the arrangement of the deflector is such that its dimension is minimized at best compared to the closest prior art while keeping its functionalities.
Selon l'invention, le deuxième boîtier comprend un peigne ou une brosse orienté vers le premier boîtier et adjacent à la deuxième surface de traitement interne. Lorsque les fonctions peigne ou brosse sont prévues en addition à la fonction lissage, l'ordre de traitement de la mèche est le suivant : peignage ou brossage puis lissage ou, dans le cas de vapeur formée, vapeur puis peignage ou brossage puis lissage. According to the invention, the second housing comprises a comb or brush oriented towards the first housing and adjacent to the second internal treatment surface. When the comb or brush functions are provided in addition to the smoothing function, the order of treatment of the wick is as follows: combing or brushing then smoothing or, in the case of vapor formed, steam then combing or brushing then smoothing.
Plus particulièrement selon l'invention, le premier boîtier présente une rainure formée en son contour intérieur et agencée en position fermée sensiblement en face du peigne ou de la brosse du deuxième boîtier. Ceci permet de recevoir au moins l'extrémité libre du peigne ou au moins l'extrémité libre de la rangée de brosse en position fermée tout en limitant l'encombrement au mieux, tout en protégeant l'extrémité de l'accessoire (peigne, brosse, etc ..) de toute tension trop forte subie pendant le passage de l'appareil en position fermée le long de la mèche et qui pourrait endommager le peigne. Le peigne ne doit pas être en butée avec le boîtier supérieur avant le contact des plaques chauffantes. More particularly according to the invention, the first housing has a groove formed in its inner contour and arranged in closed position substantially opposite the comb or brush of the second housing. This makes it possible to receive at least the free end of the comb or at least the free end of the brush row in closed position while limiting the bulk at best, while protecting the end of the accessory (comb, brush , etc.) of any excessive tension experienced during the passage of the device in closed position along the wick and which could damage the comb. The comb must not be in abutment with the upper case before contact of the hotplates.
Selon l'invention, la première poignée de la première mâchoire et la deuxième poignée de la deuxième mâchoire ont chacune une largeur Lp strictement inférieure à la plus grande largeur 11 du premier boîtier. Ceci permet d'avoir une préhension facile pour toute taille de main. Les poignées sont en prolongement axial longitudinal des boîtiers respectifs. Les bords des boîtiers qui sont en aplomb l'un de l'autre sont chacun dans une configuration particulière alignés (selon une même droite) avec les bords correspondants des poignées. L'asymétrie de l'appareil est prononcée également au niveau des poignées. According to the invention, the first handle of the first jaw and the second handle of the second jaw each have a width Lp strictly less than the largest width 11 of the first housing. This makes it easy to grip for any size of hand. The handles are in longitudinal axial extension of the respective housings. The edges of the housings which are plumb with each other are each in a particular configuration aligned (according to a same right) with the corresponding edges of the handles. The asymmetry of the device is pronounced also at the level of the handles.
Selon l'invention, la surface extérieure du premier boîtier et du deuxième boîtier au moins recouvrant la zone de traitement formée par les surfaces de traitement est substantiellement lisse. Ceci permet de glisser au mieux les mèches quand celles-ci sont enroulées autour d'un ou des deux boîtiers et qu'elles doivent être détachées sans toucher à la forme des boucles fabriquées, état de surface brillant, type Charmilles 0 ou 3 La rugosité Ra de la surface dite substantiellement lisse ira de 0,2 μιτι à 2 μιτι , plus particulièrement de 0,2 μιτι à 0,5 μιτι. Au moins une zone de préhension peut être disposée sur la surface externe des boîtiers. Cette zone de préhension est adaptée pour limiter le transfert de chaleur afin d'offrir la possibilité d'une nouvelle gestuelle sans risque de brûlures en maintenant les mâchoires par les boîtiers et non par les poignées. A titre d'exemple, la surface de cette zone de préhension peut être réalisée en un matériau différent ou peut présenter un état de surface différent du reste de surface externe de chaque boîtier. According to the invention, the outer surface of the first housing and the at least one second housing covering the treatment area formed by the treatment surfaces is substantially smooth. This makes it possible to slide the wicks the best when they are wrapped around one or both cases and they must be detached without affecting the shape of the loops manufactured, shiny surface condition, Charmilles type 0 or 3 roughness Ra of the so-called substantially smooth surface will range from 0.2 μιτι to 2 μιτι, more particularly from 0.2 μιτι to 0.5 μιτι. At least one gripping area may be disposed on the outer surface of the housings. This gripping area is adapted to limit the heat transfer to offer the possibility of a new gesture without risk of burns by keeping the jaws by the housings and not by the handles. For example, the surface of this gripping zone may be made of a different material or may have a surface state different from the rest of the outer surface of each housing.
Selon l'invention, en section transversale, la ligne définie par le contour extérieur des premier et deuxième boîtiers est une courbe arrondie ne présentant aucun point d'inflexion. Selon un aspect encore particulier, la ligne n'est visuellement jamais plane. Ceci permet de fournir un appareil à encombrement réduit, capable de former des boucles et dont le contour global est sensiblement arrondi. Pour ces raisons d'encombrement et de contenance différente des deux boîtiers, le contour extérieur n'est toutefois pas circulaire. Selon l'invention, l'appareil comporte un réservoir de fluide et des moyens de vaporisation en communication de fluide avec les moyens de sortie de vapeur et un actionneur destiné à commander les moyens de vaporisation. Ceci permet de commander la vapeur de façon séparée de la chauffe des surfaces de traitement ou lissage. L'utilisateur a le choix par cet actionneur. According to the invention, in cross section, the line defined by the outer contour of the first and second housings is a rounded curve having no point of inflection. According to a still particular aspect, the line is visually never flat. This makes it possible to provide a device with reduced space, capable of forming loops and whose overall contour is substantially rounded. For these reasons of size and different capacity of the two housings, the outer contour is however not circular. According to the invention, the apparatus comprises a fluid reservoir and vaporization means in fluid communication with the steam outlet means and an actuator for controlling the vaporization means. This allows the steam to be controlled separately from the heating of the treatment or smoothing surfaces. The user has the choice by this actuator.
Selon l'invention, les moyens de vaporisation comprennent une pompe électrique et ledit actionneur est destiné à commander la pompe électrique. Ceci permet de commander l'approvisionnement de la chambre de vaporisation indépendamment de la chauffe des surfaces de traitement ou de lissage. Ainsi, si l'utilisateur veut stopper la vaporisation, il appuie sur l'actionneur ou interrupteur pour arrêter le fonctionnement de la pompe électrique tandis que la chauffe de la chambre de vaporisation reste inchangée par l'actionnement de l'interrupteur et continue. Si l'utilisateur souhaite à nouveau de la vapeur, il actionnera l'interrupteur qui remettra en fonctionnement la pompe électrique et rendra la vapeur immédiatement opérationnelle car la chambre de vaporisation sera restée à température adéquate pendant l'arrêt de la pompe. L'utilisateur a le choix par cet actionneur entre l'arrêt de vapeur immédiat et la reprise de vapeur immédiate. According to the invention, the vaporization means comprise an electric pump and said actuator is intended to control the electric pump. This makes it possible to control the supply of the vaporization chamber independently the heating of treatment or smoothing surfaces. Thus, if the user wants to stop the vaporization, he presses the actuator or switch to stop the operation of the electric pump while the heating of the vaporization chamber remains unchanged by the operation of the switch and continues. If the user again wants steam, it will activate the switch that will turn on the electric pump and make the steam immediately operational because the steam chamber will have remained at proper temperature during the shutdown of the pump. The user has the choice by this actuator between the immediate steam stop and the immediate steam recovery.

Exposé détaillé de l'invention : Detailed description of the invention:
Comme illustré sur toutes les figures -y compris la figure 1 représentant l'art antérieur - l'appareil de coiffure 1 comporte une première mâchoire 2 et une deuxième mâchoire 3 disposées en regard l'une de l'autre. Chaque mâchoire peut être décomposée au moins fonctionnellement en deux parties : un boîtier qui tient les organes de traitement des cheveux et une poignée pour la prise en main par l'utilisateur. Chaque boîtier est formé d'une pièce. Le boîtier et la poignée peuvent être d'une seule pièce en prolongement l'un de l'autre. Ainsi la première mâchoire 2 peut être formée d'un premier boîtier 6 et de la première poignée 6' et la deuxième mâchoire 3 peut être formée du deuxième boîtier 7 et de la deuxième poignée 7'. La première surface de traitement interne 4 est portée par la première mâchoire 2, plus précisément par le premier boîtier 6, la deuxième surface de traitement interne 5 est portée par la deuxième mâchoire 3, plus précisément par le deuxième boîtier 7. Les deux mâchoires 2, 3 sont reliées de sorte à passer entre une position ouverte et une position fermée dans laquelle les surfaces de traitement internes 4, 5 pincent une mèche de cheveux. La première surface 4 et la deuxième surface 5 de traitement des cheveux sont des surfaces complémentaires plates qui, en position fermée de l'appareil, viennent sensiblement en correspondance pour pincer la mèche de cheveux permettant ainsi de la lisser quand la mèche est passée en glissement par translation droite. Les deux surfaces de traitement sont substantiellement symétriques par rapport au plan de lissage lorsque l'appareil est en position fermée. De même les éléments de chauffage de chaque surface de traitement sont substantiellement symétriques par rapport au plan de lissage lorsque l'appareil est en position fermée. As illustrated in all the figures -including FIG. 1 representing the prior art-the hairdressing appliance 1 comprises a first jaw 2 and a second jaw 3 arranged opposite one another. Each jaw can be broken down at least functionally into two parts: a housing that holds the hair treatment members and a handle for the grip by the user. Each housing is formed of a room. The housing and the handle may be in one piece extending from one another. Thus the first jaw 2 can be formed of a first housing 6 and the first handle 6 'and the second jaw 3 can be formed of the second housing 7 and the second handle 7'. The first internal processing surface 4 is carried by the first jaw 2, more precisely by the first housing 6, the second internal processing surface 5 is carried by the second jaw 3, more precisely by the second housing 7. The two jaws 2 , 3 are connected so as to pass between an open position and a closed position in which the internal treatment surfaces 4, 5 pinch a lock of hair. The first surface 4 and the second surface 5 of hair treatment are flat complementary surfaces which, in the closed position of the apparatus, come substantially in correspondence to pinch the lock of hair thereby smoothing it when the wick is slid by straight translation. The two treatment surfaces are substantially symmetrical with respect to the smoothing plane when the apparatus is in the closed position. Likewise, the heating elements of each treatment surface are substantially symmetrical with respect to the smoothing plane when the apparatus is in the closed position.
La première mâchoire 2 et la deuxième mâchoire 3 sont reliées par une articulation de type charnière et l'angle maximum a d'ouverture des deux mâchoires est compris entre 5° et 60°, voire entre 10° et 20°, et préférentiellement environ égal à 15°. De plus, l'appareil toujours illustré ici est en position de repos « ouverte », mais il peut être en position de repos « fermée », comme illustré dans le brevet EP2145557, lesdites mâchoires étant montées pivotantes à l'autre extrémité entre une position d'ouverture permettant l'insertion des cheveux entre les deux surfaces de traitement et une position de fermeture pour leur mise en contact avec les deux surfaces de traitement, l'appareil comporte des moyens de rappel des demi poignées qui provoquent la mise en pression des surfaces de traitement. L'axe de pivotement des deux mâchoires supportant les surfaces de traitement peut être placé à l'extrémité des mâchoires (comme illustré ici) ou être placé environ au milieu des mâchoires pour fournir un appareil à articulation du type « ciseaux ». The first jaw 2 and the second jaw 3 are connected by a hinge type hinge and the maximum opening angle α of the two jaws is between 5 ° and 60 °, or even between 10 ° and 20 °, and preferably about equal at 15 °. In addition, the apparatus still illustrated here is in the "open" rest position, but it can be in the "closed" rest position, as illustrated in patent EP2145557, said jaws being pivotally mounted at the other end between a position opening for the insertion of the hair between the two treatment surfaces and a closed position for bringing them into contact with the two treatment surfaces, the apparatus comprises means for returning the half-handles which cause the pressurizing of the treatment surfaces. The pivot axis of both Jaws supporting the treatment surfaces can be placed at the end of the jaws (as shown here) or placed approximately in the middle of the jaws to provide a "scissors" type hinge apparatus.
Le matériau formant les surfaces de traitement 4,5 est composé de métal et/ou céramique et/ou verre et/ou matériau plastique et/ou pièce en fibre. Au moins un parmi les premier et deuxième boîtiers présente un unique élément chauffant destiné à chauffer par contact la surface de traitement correspondante et par rayonnement le revêtement. La surface de traitement est capable de monter à une température comprise entre 130 et 230°C. Le boîtier et la poignée externe sont en une pièce pour former la mâchoire. Le matériau formant la partie externe du boîtier voire aussi la partie externe de la poignée peut être du plastique, par exemple du PBT (polybutylène terephtalate) chargé fibre de verre. Il est important que ce matériau présente une surface très lisse. Le matériau formant la partie interne du boîtier voire aussi la partie interne de la poignée peut être du plastique, par exemple du PET (polyéthylène téréphtalate) chargé fibre de verre. The material forming the treatment surfaces 4,5 is composed of metal and / or ceramic and / or glass and / or plastic material and / or fiber part. At least one of the first and second housings has a single heating element for contact heating the corresponding treatment surface and radiation coating. The treatment surface is capable of mounting at a temperature between 130 and 230 ° C. The case and the external handle are in one piece to form the jaw. The material forming the outer portion of the housing or even the outer portion of the handle may be plastic, for example PBT (polybutylene terephthalate) loaded glass fiber. It is important that this material has a very smooth surface. The material forming the inner part of the housing or even the inner part of the handle may be plastic, for example PET (polyethylene terephthalate) loaded glass fiber.
Comme illustré en figure 4, l'appareil 1 comprend au moins des moyens de chauffage 41 pour chauffer la première surface de traitement 4. Selon un mode particulier, l'appareil 1 comprend également des moyens de chauffage 51 pour chauffer la deuxième surface de traitement. Le ou les moyens de chauffage 41 , 51 peut ou peuvent être un élément chauffant qui peut être une thermistance CTP (coefficient de température positif) ou une céramique qui est plaquée contre la surface de traitement 4, 5 ou agencée à l'intérieur de l'élément comprenant la surface de traitement 4, 5.  As illustrated in FIG. 4, the apparatus 1 comprises at least heating means 41 for heating the first treatment surface 4. According to a particular embodiment, the apparatus 1 also comprises heating means 51 for heating the second treatment surface . The heating means (s) 41, 51 may or may be a heating element which may be a PTC thermistor (positive temperature coefficient) or a ceramic which is pressed against the treatment surface 4, 5 or arranged inside the heating element. element comprising the treatment surface 4, 5.
Comme illustré en figure 4, l'appareil 1 comprend dans un mode de réalisation des moyens de vaporisation 80 du fluide comportant une chambre de vaporisation As illustrated in FIG. 4, the apparatus 1 comprises, in one embodiment, vaporization means 80 for the fluid comprising a vaporization chamber.
81 et des moyens de chauffage (ou élément de chauffage ou élément chauffant)81 and heating means (or heating element or heating element)
82 de la chambre de vaporisation. La ou les chambres de vaporisation sont réalisées en aluminium, peuvent comporter des moyens de sortie de vapeur 31 qui peuvent être formés par un ou des orifices de distribution de vapeur, par exemple une rangée d'orifices. La ou les chambres de vaporisation 81 peuvent être plaquées en contact direct ou indirect contre l'élément de chauffage 82 associé. Le bon écrasement de l'élément chauffant 82 et donc son fonctionnement optimal se fait par une lame ressort (non illustrée) par exemple. Un capteur de température peut être préférentiellement agencé au dessus de l'arrivée de fluide dans la chambre. Les moyens de chauffage 82 de la chambre de vaporisation peuvent être au moins un élément chauffant qui peut être une thermistance CTP (coefficient de température positif) ou une céramique qui est plaquée contre une des parois ou agencée à l'intérieur de l'élément formant la surface de traitement, ils peuvent être identiques ou séparés des moyens de chauffage de la surface de traitement. Les moyens de distribution ou moyens de sortie de la vapeur 31 peuvent présenter une série d'orifices de sortie de vapeur agencée latéralement à la première surface de traitement 4, préférentiellement un peu en retrait de la surface de traitement 4. Alternativement ou additionnellement les moyens de distribution de la vapeur présentent une série d'orifices agencés sur la surface de traitement. Le débit en sortie de vapeur est d'environ entre 3 et 4g/min, plutôt environ égal à 3.5g/min. La construction intérieure de l'appareil et notamment des moyens de vaporisation est entièrement détaillée dans le brevet de la demanderesse EP2449909. 82 of the vaporization chamber. The vaporization chamber or chambers are made of aluminum, may include steam outlet means 31 which may be formed by one or more steam distribution orifices, for example a row of orifices. The vaporization chamber (s) 81 may be plated in direct or indirect contact against the associated heating element 82. The good crushing of the heating element 82 and therefore its optimal operation is done by a spring blade (not shown) for example. A temperature sensor may preferably be arranged above the fluid inlet in the chamber. The heating means 82 of the vaporization chamber may be at least one heating element which may be a PTC thermistor (positive temperature coefficient) or a ceramic which is pressed against one of the walls or arranged inside the element forming the treatment surface, they may be identical or separate from the heating means of the treatment surface. The dispensing means or steam outlet means 31 may have a series of steam outlet orifices arranged laterally to the first treatment surface 4, preferably a little behind the treatment surface 4. Alternatively or additionally the means vapor distribution have a series of orifices arranged on the treatment surface. The flow rate at the steam outlet is approximately between 3 and 4 g / min, more or less equal to 3.5 g / min. The interior construction of the apparatus and in particular the means of vaporization is fully detailed in the patent of applicant EP2449909.
Comme illustré en figures 2, 3 et 4, l'appareil de coiffure 1 pour le bouclage et le lissage de cheveux a sa plus grande largeur 11 du premier boîtier 6 inférieure ou égale à 90% de la plus grande largeur 12 du deuxième boîtier 7. Plus particulièrement, la plus grande largeur 11 du premier boîtier 6 est comprise entre 75% et 85% de la plus grande largeur 12 du deuxième boîtier 7, préférentiellement égale à 80%. Ces plus grandes largeurs sont substantiellement constantes sur le boîtier, sauf sur les extrémités de chaque boîtier, c'est pourquoi est donnée une fourchette de valeur. La figure 4 est d'ailleurs une coupe en section sensiblement au milieu des boîtiers. As illustrated in Figures 2, 3 and 4, the hairstyling device 1 for looping and straightening hair has its largest width 11 of the first housing 6 less than or equal to 90% of the largest width 12 of the second housing 7 More particularly, the largest width 11 of the first housing 6 is between 75% and 85% of the largest width 12 of the second housing 7, preferably equal to 80%. These larger widths are substantially constant on the housing, except on the ends of each housing, which is why a value range is given. Figure 4 is also a sectional section substantially in the middle of the housings.
En position fermée des mâchoires 2, 3, comme illustré en figures 3 et 4, le plan médian ou encore plan sagittal P1 en coupe longitudinale du premier boîtier 6 est parallèle à et distinct du plan médian P2 en coupe longitudinale du deuxième boîtier 7. La distance entre les deux plans médians ou sagittaux P1 , P2 est comprise entre 5% et 20% de la largeur de la plus grande largeur 12 du deuxième boîtier 7, préférentiellement égale à 10%. Ainsi le corps des deux boîtiers n'est pas symétrique selon un plan longitudinal transversal mais décalé. Le contour de l'appareil est clairement asymétrique et est utilisé judicieusement autant pour diminuer l'encombrement des éléments intérieurs que pour faciliter le procédé d'usage du lisseur visant à former des boucles de taille différente. Comme représenté en figures 3 et 4, en position fermée des mâchoires 2 et 3, un des deux bords longitudinaux 61 du premier boîtier 6 est à l'aplomb du bord longitudinal 71 du deuxième boîtier 7 agencé du même côté du deuxième boîtier 7. Le plan longitudinal transversal P4 et respectivement plan longitudinal transversal P5 sont le plan médian de la surface de traitement interne 4, respectivement de la surface de traitement interne 5. En coupe illustrée en figure 4, ce plan P4 est parallèle et décalé vers l'extérieur par rapport aux plans P1 et P2. Les plans P4, P1 et P2 sont parallèles entre eux et sont chacun orthogonaux au plan de lissage Pl. De plus le premier boîtier 6 et le second boîtier 7 de cet exemple sont également asymétriques par rapport à leur plan médian respectif (P1 , P2) en coupe longitudinale. In the closed position of the jaws 2, 3, as illustrated in FIGS. 3 and 4, the median or sagittal plane P1 in longitudinal section of the first housing 6 is parallel to and distinct from the median plane P2 in longitudinal section of the second housing 7. The distance between the two median or sagittal planes P1, P2 is between 5% and 20% of the width of the largest width 12 of the second housing 7, preferably equal to 10%. Thus the body of the two housings is not symmetrical in a transverse longitudinal plane but offset. The outline of the device is clearly asymmetrical and is used judiciously as much to reduce the size of the interior elements as to facilitate the process of using the straightener to form loops of different size. As shown in FIGS. 3 and 4, in the closed position of the jaws 2 and 3, one of the two longitudinal edges 61 of the first casing 6 is in line with the longitudinal edge 71 of the second casing 7 arranged on the same side of the second casing 7. transverse longitudinal plane P4 and respectively transverse longitudinal plane P5 are the median plane of the internal processing surface 4, respectively of the internal processing surface 5. In section illustrated in FIG. 4, this plane P4 is parallel and offset outwards by compared to plans P1 and P2. The planes P4, P1 and P2 are parallel to each other and are each orthogonal to the smoothing plane P1. In addition, the first housing 6 and the second housing 7 of this example are also asymmetrical with respect to their respective median plane (P1, P2). in longitudinal section.
Comme on l'a vu, les surfaces de traitement interne 4, 5 sont planes, identiques, sont en regard l'une de l'autre en position fermée, et sont agencées dans leurs boîtiers respectifs 6, 7 à côté et voisines desdits bords en aplomb 61 , 71 . Sur la figure 4 est représentée la droite l'aplomb, droite tangente aux bords 61 et 71 des boîtiers ou capots en aplomb. Cette droite est orthogonale au plan de lissage Pl. Les courbes des contours Ii6, respectivement Ii7, des boîtiers 6 et 7, forment un arc de cercle qui est substantiellement continu au niveau des bords 61 et 71 en aplomb et donc la valeur de l'arc de cercle est environ de 15mm. As we have seen, the internal treatment surfaces 4, 5 are planar, identical, are facing each other in the closed position, and are arranged in their respective housings 6, 7 adjacent and adjacent said edges in line 61, 71. In Figure 4 is shown the straight line, straight tangent to the edges 61 and 71 of the housings or hoods plumb. This straight line is orthogonal to the plane of smoothing Pl. The curves of the contours Ii6, respectively Ii7, of the housings 6 and 7 form an arc of a circle which is substantially continuous at the edges 61 and 71 in a plumb and therefore the value of the arc of circle is about 15mm.
Chacun desdits deux bords longitudinaux 61 , 71 est muni en interne d'une barrette protubérante 62, 72 vers l'intérieur de l'appareil préférentiellement en même matériau (plastique par exemple PBT) que celui desdits boîtiers 6, 7. Ces barrettes sont agencées de façon identique sur les deux boîtiers comme illustré en figure 5. Elles permettent d'appliquer une tension pour donner un effet dit « bolduc » aux cheveux qui glissent sur une de ces barrettes pendant le geste de lissage. C'est une première façon de former des boucles vers l'intérieur ou respectivement vers l'extérieur, en fonction de la barrette utilisée, la barrette agencée en bas, respectivement agencée en haut du lisseur utilisé. Each of said two longitudinal edges 61, 71 is internally provided with a protruding bar 62, 72 towards the inside of the device, preferably of the same material (plastic for example PBT) as that of said housings 6, 7. These strips are arranged identically on the two housings as shown in Figure 5. They allow to apply a voltage to give a so-called "bolduc" effect to the hair that slide on one of these bars during the smoothing gesture. This is a first way of forming loops inward or outwardly, depending on the bar used, the bar arranged at the bottom, respectively arranged at the top of the straightener used.
Comme illustré en figures 2 et 4, la largeur I de chaque surface de traitement interne 4, 5 est comprise entre 40% et 60% de la plus grande largeur 11 du premier boîtier 6, préférentiel lement entre 40% et 50%, voire sensiblement égale à 45%. As illustrated in FIGS. 2 and 4, the width I of each treatment surface internal 4, 5 is between 40% and 60% of the largest width 11 of the first housing 6, preferably between 40% and 50%, or even substantially equal to 45%.
Comme illustré en figure 4, voici un exemple non limitatif des dimensions de l'appareil selon l'invention :  As illustrated in FIG. 4, here is a nonlimiting example of the dimensions of the apparatus according to the invention:
11 : plus grande largeur du premier boîtier 6 = 45mm  11: greater width of the first housing 6 = 45mm
12 : plus grande largeur du deuxième boîtier 7= 52mm  12: greater width of the second housing 7 = 52mm
h1 : plus grande hauteur du premier boîtier 6 = 23mm h1: greater height of the first housing 6 = 23mm
h2 : plus grande hauteur du deuxième boîtier 7= 32mm h2: greater height of the second case 7 = 32mm
I : largeur de chaque surface de traitement interne 4, 5= 25mm I: width of each internal treatment surface 4, 5 = 25mm
r : rayon de courbure formé par le contour de chaque côté du premier boîtier 6 : environ 14mm. r: radius of curvature formed by the contour of each side of the first housing 6: about 14mm.
Le lisseur selon l'invention présente sa deuxième mâchoire 3 comprenant des moyens de sortie de vapeur 31 orientés vers le premier boîtier 6 et adjacents à la deuxième surface de traitement interne 5. Précisément, ceci signifie que la première mâchoire 2 comporte pour le traitement des cheveux seulement une plaque de lissage, tandis que la deuxième mâchoire présente pour le traitement des cheveux une plaque de lissage et au moins une fonction coiffure supplémentaire. Ladite au moins une fonction coiffure supplémentaire peut être une ou plusieurs fonctions choisies parmi la liste des suivantes : vaporisation, peignage, brossage, ionisation, application de tension par une barrette en matériau type silicone, application d'une tension par une barrette mobile entraînée par exemple en mouvement oscillatoire. La présente invention permet ainsi de fournir un appareil de coiffure compact avec une fonction coiffure supplémentaire à celle du lissage et avec la capacité de former des boucles d'au moins deux tailles différentes, voire d'au moins trois tailles différentes. Pour ce faire, ladite fonction coiffure supplémentaire est embarquée sur le boîtier le plus large des deux. L'invention réside dans la meilleure réduction de la largeur du boîtier de mâchoire ne présentant que la fonction lissage sans que celle-ci n'entraîne de dysfonctionnement ni en termes de sécurité ni en termes d'efficacité de l'appareil de coiffure complet. Aussi, la formation des boucles ainsi que le « démoulage » des boucles ont représenté une contrainte supplémentaire sur la dimension et sur la forme des boîtiers. The straightener according to the invention has its second jaw 3 comprising steam outlet means 31 oriented towards the first housing 6 and adjacent to the second internal treatment surface 5. Precisely, this means that the first jaw 2 comprises for the treatment of hair only a smoothing plate, while the second jaw has for hair treatment a smoothing plate and at least one additional hair function. Said at least one additional hairdressing function can be one or more functions selected from the following list: vaporization, combing, brushing, ionization, application of tension by a bar of silicone-type material, application of a voltage by a mobile bar driven by example in oscillatory motion. The present invention thus makes it possible to provide a compact hairdressing appliance with a hairdressing function that is additional to that of smoothing and with the ability to form loops of at least two different sizes, or even at least three different sizes. To do this, said additional hairdressing function is embedded on the widest case of both. The invention lies in the best reduction in the width of the jaw housing exhibiting only the smoothing function without the latter causing any malfunction in terms of safety or in terms of efficiency of the complete hairdressing appliance. Also, the formation of the loops as well as the "loosening" of the buckles represented an additional constraint on the size and on the shape of the housings.
Dans le cas où une fonction vapeur est embarquée sur la deuxième mâchoire 3, il peut être important que le premier boîtier 6 présente un déflecteur 21 formé dans son contour intérieur et agencé en position fermée sensiblement en face des moyens de sortie de vapeur 31 du deuxième boîtier 7. Ce déflecteur permet de protéger le cuir chevelu de toute projection indésirée de vapeur ou de gouttelettes d'eau chaude condensées. Ce déflecteur 21 permet de renvoyer la vapeur vers le cheveu qui sera traversé deux fois par la vapeur. Le déflecteur selon l'art antérieur illustré en figure 1 était très large, était plat et recouvrait toute la dimension de la mâchoire en regard. Le dimensionnement du déflecteur 21 de l'invention illustré en figure 4 a été judicieusement choisi par les inventeurs pour garder cette fonction : la dimension en largeur est diminuée autant que faire se peut de sorte qu'il recouvre juste les orifices de sortie de vapeur 31 . De plus la forme de ce déflecteur est modifiée : il n'est plus plat comme illustré en figure 1 , mais le contour interne du premier boîtier 6 est incliné vers le haut pour représenter le déflecteur. In the case where a steam function is embarked on the second jaw 3, it may be important that the first housing 6 has a deflector 21 formed in its inner contour and arranged in a closed position substantially opposite the steam outlet means 31 of the second 7. This baffle protects the scalp from unwanted projection of steam or condensed hot water droplets. This deflector 21 makes it possible to return the steam towards the hair which will be crossed twice by the steam. The deflector according to the prior art illustrated in FIG. 1 was very wide, was flat and covered the entire dimension of the jaw opposite. The sizing of the deflector 21 of the invention illustrated in FIG. 4 has been judiciously chosen by the inventors to maintain this function: the width dimension is reduced as much as possible so that it just covers the steam outlet orifices 31 . In addition the shape of this deflector is changed: it is flatter as shown in Figure 1, but the inner contour of the first housing 6 is inclined upward to represent the deflector.
Comme illustré en figure 4, le deuxième boîtier 7 comprend un peigne ou une brosse 32 orienté vers le premier boîtier 6 et adjacent à la deuxième surface de traitement interne 5. Dans ce cas, le premier boîtier 6 peut présenter une rainure 22 formée en son contour intérieur et agencée en position fermée sensiblement en face du peigne ou de la brosse 32 du deuxième boîtier 7. De cette façon, le peigne sépare bien toute l'épaisseur de la mèche sans que la fonction peignage ne prenne trop d'espace.  As illustrated in FIG. 4, the second housing 7 comprises a comb or a brush 32 oriented towards the first housing 6 and adjacent to the second internal treatment surface 5. In this case, the first housing 6 may have a groove 22 formed in its housing. inner contour and arranged in closed position substantially opposite the comb or the brush 32 of the second housing 7. In this way, the comb separates well the entire thickness of the wick without the combing function takes too much space.
Comme illustré en figures 2 et 3, la première poignée 6' de la première mâchoire 2 et la deuxième poignée 7' de la deuxième mâchoire 3 ont chacune une largeur Ip strictement inférieure à la plus grande largeur 11 du premier boîtier 6, c'est -à- dire à la plus petite des largeurs sur les deux boîtiers 6 et 7. Aussi les bords des boîtiers 6 et 7 qui sont agencés à l'aplomb sont dans ces cas alignés avec le bord du même côté des poignées pour former une droite d'alignement confondue Laii comme illustrée en figure 2. Il s'avère que cet alignement augmente l'ergonomie de l'appareil qui peut être manié par toute taille de main. As illustrated in FIGS. 2 and 3, the first handle 6 'of the first jaw 2 and the second handle 7' of the second jaw 3 each have a width Ip that is strictly smaller than the largest width 11 of the first housing 6; that is to say, the smallest width on the two housings 6 and 7. Also the edges of the housings 6 and 7 which are arranged vertically are in these cases aligned with the edge of the same side of the handles to form a straight line Laii alignment alignment as illustrated in Figure 2. It turns out that this alignment increases the ergonomics of the device that can be handled by any hand size.
La surface extérieure du premier boîtier 6 et du deuxième boîtier 7 est substantiellement lisse. Le coefficient de frottement a été mesuré via des mesures de la rugosité de la coque au niveau de la zone destinée à l'enroulement des boucles comme suit : The outer surface of the first housing 6 and the second housing 7 is substantially smooth. The coefficient of friction was measured via measurements of the roughness of the shell at the area intended for the winding of the loops as follows:
a) Mesure du Ra sur la partie supérieure « plane » ou encore la partie tangentielle à l'horizontale de la coque 6 illustrée en figure 4 :  a) Measurement of Ra on the "flat" upper part or the horizontal tangential part of the shell 6 illustrated in FIG. 4:
En sens longitudinal : 0,24 ; 0,23 ; 0,22 μιτι soit 0,23 μιτι en moyenne, En sens transversal : 0,22 ; 0,44 ; 0,27 μιτι soit 0,31 μιτι en moyenne b) Mesure du Ra sur la partie latérale, à gauche et à droite du boîtier 6 illustré en figure 4 :  In the longitudinal direction: 0.24; 0.23; 0.22 μιτι, that is 0.23 μιτι on average, In transverse direction: 0.22; 0.44; 0.27 μιτι, ie 0.31 μιτι on average b) Measurement of Ra on the lateral part, on the left and on the right of the case 6 illustrated in FIG. 4:
En sens longitudinal : 0,24; 0,23; 0,43; 1 ,63 μιτι soit 0,24 μιτι en moyenne avec des pics localisés pouvant aller jusqu'à 1 ,63μηη ;  In the longitudinal direction: 0.24; 0.23; 0.43; 1, 63 μιτι is 0.24 μιτι on average with localized peaks up to 1, 63μηη;
Le rugosimètre utilisé est de marque Mitutoyo, n° JP1010. Le critère statistique Ra est statistique, et c'est l'écart moyen arithmétique par rapport à la ligne moyenne. The rugosimeter used is Mitutoyo brand, No. JP1010. The statistical criterion R a is statistical, and it is the arithmetic average deviation from the mean line.
Ceci permet un enroulement et un « démoulage » des boucles facile sans abimer la mèche de cheveux. This allows easy curling and "unmolding" of the loops without damaging the lock of hair.
En section transversale comme illustré en figure 4, la ligne définie par le contour extérieur des premier et deuxième boîtiers 6, 7 est une courbe arrondie ne présentant aucun point d'inflexion. Une majeure partie du travail a été de définir au mieux un contour des boîtiers le plus arrondi et le plus fluide possible, sans point d'inflexion et en fonction de l'encombrement des éléments intérieurs et des mesures de sécurité et d'efficacité fixées par l'appareil. On remarque qu'en coupe transversale, il n'y a aucune ligne plane visuellement détectable à l'œil nu. Au niveau du premier boîtier, celui-ci présente des arcs de cercle sur les côtés plus petits que les arcs de cercle sur les côtés du deuxième boîtier. Les rayons de courbure de chaque côté du premier boîtier 6 sont sensiblement identiques. Ceci permet de former des boucles les plus rondes possibles. Ceci permet aussi d'éviter des angles sur l'appareil fragiles aux chocs. En vue de coupe, le contour extérieur du premier boîtier 6 est à peu près une réduction du contour extérieur en section transversale du deuxième boîtier 7 de rapport environ égal à 0,8.  In cross-section as illustrated in FIG. 4, the line defined by the outer contour of the first and second housings 6, 7 is a rounded curve having no point of inflection. A major part of the work has been to define at best an outline of the housings as rounded and as fluid as possible, without point of inflection and depending on the size of the interior elements and the safety and efficiency measures set by the device. Note that in cross section, there is no flat line visually detectable to the naked eye. At the first housing, it has arcs on the sides smaller than the arcs on the sides of the second housing. The radii of curvature on each side of the first housing 6 are substantially identical. This makes it possible to form the roundest loops possible. This also avoids angles on the device fragile to shocks. In sectional view, the outer contour of the first housing 6 is approximately a reduction of the outer contour in cross section of the second housing 7 of about 0.8 ratio.
Selon l'invention, l'appareil comporte un réservoir de fluide 83 et des moyens de vaporisation 80 en communication de fluide avec les moyens de sortie de vapeur 31 et un actionneur 85 destiné à commander les moyens de vaporisation 80. Plus particulièrement, les moyens de vaporisation 80 comprennent une pompe électrique 84 et ledit actionneur 85 est destiné à commander la pompe électrique 84. Ceci permet de commander l'approvisionnement de la chambre de vaporisation 81 indépendamment de la chauffe des surfaces de traitement ou de lissage 4, 5. L'utilisateur a le choix par cet actionneur 85. S'il veut faire des boucles avec ou sans vapeur, l'utilisateur intervient sur l'actionneur directement. La pompe électrique peut être une pompe péristaltique dont l'actionneur 85 commandera le moteur.

Description en fonctionnement de l'invention: Description in operation of the invention:
En fonctionnement, l'utilisateur va brancher l'alimentation électrique de l'appareil, l'élément chauffant type CTP ou céramique se met à chauffer les surfaces destinées à venir en contact avec les cheveux, et un élément chauffant séparé (ou le même élément chauffant) se met à chauffer les moyens de vaporisation 80 (quand il s'agit d'une fonction vapeur), l'utilisateur saisit l'appareil et l'applique pour venir pincer la mèche de cheveux à traiter.  In operation, the user will connect the power supply of the apparatus, the heating element type CTP or ceramic will heat the surfaces intended to come into contact with the hair, and a separate heating element (or the same element heating) starts to heat the vaporization means 80 (when it is a steam function), the user grasps the device and applies it to pinch the lock of hair to be treated.
Comme les deux boîtiers sont asymétriques, l'agencement de l'appareil sur la mèche a de l'importance : l'utilisateur doit agencer et fermer le lisseur pour que les deux côtés à l'aplomb soient les plus proches du cuir chevelu, le sens est illustré en figure 2. Ensuite, l'utilisateur peut effectuer l'étape classique de lissage en glissant les cheveux de façon rectiligne le long de la mèche dans le sens représenté par la flèche dessinée sur le premier boîtier 6 des figures 2 et 3.  As the two housings are asymmetrical, the arrangement of the device on the wick is important: the user must arrange and close the straightener so that the two sides to the plumb are closest to the scalp, the 2, the user can then perform the conventional smoothing step by sliding the hair straight along the wick in the direction represented by the arrow drawn on the first housing 6 of FIGS. 2 and 3. .
Lorsque l'utilisateur souhaite former des boucles de petite taille, il procède comme suit : l'appareil 1 étant en position ouverte, il entoure le premier boîtier 6 avec la mèche de cheveux, puis il ferme le lisseur au plus près du cuir chevelu, le maintient immobile plusieurs secondes et glisse ensuite l'appareil 1 vers l'extrémité libre de la mèche pour « démouler » la mèche. Ceci permet de former des boucles et de petite taille. Lorsque l'utilisateur souhaite former des boucles de plus grande taille, il procède comme suit : une fois l'appareil fermé au plus proche du cuir chevelu, il glisse le long de toute la mèche et , à l'extrémité de la mèche, il garde l'appareil en position fermée et le tourne sur lui-même pour enrouler la mèche autour des deux boîtiers 6, 7 en position fermée jusqu'au cuir chevelu, puis, après quelques secondes, il déroule la mèche. Ceci permet de former des boucles lissées brillantes et de grande taille. When the user wishes to form small loops, he proceeds as follows: the apparatus 1 being in the open position, it surrounds the first housing 6 with the lock of hair, then it closes the straightener closer to the scalp, keeps it still for several seconds and then slides the device 1 towards the free end of the wick to "unmold" the wick. This makes it possible to form loops and of small size. When the user wishes to form loops of larger size, it proceeds as follows: once the closed device closer to the scalp, it slides along the whole wick and, at the end of the wick, it keeps the device in the closed position and turns on itself to wind the wick around the two housings 6, 7 in the closed position to the scalp, then, after a few seconds, it unrolls the wick. This makes it possible to form glossy smooth loops of large size.
Chaque étape statique peut durer quelques secondes voire une ou deux minutes, le temps que les boucles se forment correctement. La durée de pause varie notamment selon la température de l'appareil et selon le format de mèche traitée.  Each static step can last a few seconds or even a minute or two, the time that the loops are formed correctly. The pause time varies depending on the temperature of the device and the wicking format treated.
