Description

La présente invention concerne le domaine technique des appareils de coiffure destinés à la mise en forme des cheveux. L'invention concerne plus particulièrement le domaine technique des appareils du type fer à lisser comprenant au moins une plaque de lissage chauffante.The present invention relates to the technical field of hairdressing apparatus for shaping hair. The invention relates more particularly to the technical field of devices of the type smoothing iron comprising at least one heating smoothing plate.

De nombreux types de fers à lisser connus comprennent deux mâchoires montées sur une charnière pour former une pince pouvant passer entre une position ouverte et une position fermée. Les fers à lisser connus à ce jour comprennent souvent dans chacune des mâchoires un élément chauffant sous une plaque de lissage, l'ensemble étant contenu dans un boîtier de la mâchoire. Pendant l'utilisation de l'appareil, la plaque de lissage est souvent chauffée à plus de 130°C ce qui entraine une augmentation de la température du boîtier par transmission thermique. Quand il s'agit d'un lisseur vapeur, la présence d'une chambre de vapeur dans la mâchoire est susceptible d'augmenter davantage la température du boîtier.Many known types of straightening irons comprise two jaws mounted on a hinge to form a clamp capable of passing between an open position and a closed position. Hair straighteners known to date often include in each of the jaws a heating element under a smoothing plate, the assembly being contained in a housing of the jaw. During the use of the apparatus, the smoothing plate is often heated to more than 130 ° C which causes an increase in the temperature of the housing by thermal transmission. When it is a vapor straightener, the presence of a steam chamber in the jaw is likely to further increase the temperature of the housing.

Or, selon l'utilisation de ces appareils, certains coiffeurs ou utilisateurs sont amenés à utiliser une main pour maintenir la fermeture de la pince pour pouvoir faire des boucles ou pour obtenir un meilleur résultat de lissage et ce, d'une manière plus efficace à l'extrémité opposée de la charnière qui présente la zone la plus chauffée du boîtier. Le fait que les doigts soient en contact directement avec cette partie du boîtier présente un risque de brûlure ou au moins une sensation désagréable lors d'un contact avec cette partie.However, according to the use of these devices, some hairdressers or users are led to use a hand to maintain the closure of the clamp to be able to make loops or to obtain a better smoothing result and this, in a more effective way to the opposite end of the hinge which has the hottest area of the housing. The fact that the fingers are in direct contact with this part of the housing presents a risk of burning or at least an unpleasant sensation when in contact with this part.

Afin de remédier à ce problème, plusieurs documents sont connus avec un système d'isolation thermique sur le boîtier de la mâchoire afin d'éviter le contact direct avec les doigts.In order to remedy this problem, several documents are known with a thermal insulation system on the housing of the jaw to avoid direct contact with the fingers.

Par exemple, le document EP2433519 décrit un lisseur comprenant deux mâchoires montées sur charnière, chaque mâchoire comprenant sur l'extrémité opposée à la charnière une pièce rapportée au boîtier. Cette pièce permet une prise de l'appareil agréable avec les pouces pendant sa fermeture tout en fournissant une isolation thermique du boîtier. Cependant, une telle pièce intégrée au boîtier n'est pas suffisante pour faire baisser la température à cause de la conduction de chaleur transmise à la pièce. De plus, cette pièce rapportée ne permet pas d'avoir une surface lisse du boîtier.For example, the document EP2433519 discloses a straightener comprising two jaws mounted on hinge, each jaw comprising on the end opposite the hinge a piece attached to the housing. This piece allows a pleasant grip of the device with the thumbs during its closure while providing a thermal insulation of the case. However, such a room integrated in the housing is not sufficient to lower the temperature because of the heat conduction transmitted to the room. In addition, this insert does not allow to have a smooth surface of the housing.

On connait un autre document EP2687118 au nom de la demanderesse qui décrit un lisseur comprenant un peigne sur au moins un coté de la plaque de lissage, le peigne étant monté détachable par rapport au boîtier du lisseur. Néanmoins, ce document ne prévoit pas de moyen d'isolation thermique de l'appareil.We know another document EP2687118 in the name of the applicant which describes a straightener comprising a comb on at least one side of the smoothing plate, the comb being detachably mounted relative to the straightener housing. Nevertheless, this document does not provide any means of thermal insulation of the apparatus.

Le but de la présente invention est de remédier au moins en partie aux inconvénients précités et de proposer un appareil de coiffure présentant moins de risque de brûlure et une sensation plus agréable lors d'un contact avec le boîtier.The object of the present invention is to remedy at least in part the aforementioned drawbacks and to provide a hairdressing appliance with less risk of burning and a more pleasant sensation when in contact with the housing.

Un autre but de l'invention est un appareil de coiffure ayant un boitier avec une surface lisse qui est adapté à plusieurs types de mise en forme des cheveux, tel que du lissage et du styling.Another object of the invention is a hairdressing apparatus having a box with a smooth surface that is adapted to several types of shaping of the hair, such as smoothing and styling.

Un autre but de l'invention est un appareil de coiffure comprenant un moyen d'isolation thermique compact, à faible coût et facile à produire en grande quantité.Another object of the invention is a hairdressing apparatus comprising a compact thermal insulation means, low cost and easy to produce in large quantities.

Un autre but de l'invention est un appareil de coiffure ergonomique qui est facile à manipuler pendant l'utilisation.Another object of the invention is an ergonomic hairdressing apparatus which is easy to handle during use.

Ces buts sont atteints avec un appareil de coiffure du type lisseur, comprenant

  • deux bras montés sur une charnière dont au moins un bras comprend un boîtier présentant une extrémité proximale formant une zone de préhension et une extrémité distale intégrant une plaque chauffante, lesdits bras étant configurés pour former une pince permettant à ladite plaque chauffante de mettre en forme des cheveux;
  • au moins un accessoire assemblé de façon détachable avec ledit bras et présentant une base destinée à coulisser dans une rainure du bras destinée à recevoir et maintenir ladite base.
These goals are achieved with a hair straightener, comprising
  • two arms mounted on a hinge of which at least one arm comprises a housing having a proximal end forming a gripping zone and a distal end incorporating a heating plate, said arms being configured to form a clamp allowing said hotplate to shape hair;
  • at least one accessory detachably assembled with said arm and having a base for sliding in a groove of the arm for receiving and holding said base.

Selon l'invention, l'appareil comprend un moyen d'isolation thermique formant une zone d'appui destiné à couvrir au moins partiellement l'extrémité distale dudit boîtier, et ledit accessoire comprend un moyen de liaison reliant de façon solidaire ledit moyen d'isolation thermique à la base.According to the invention, the apparatus comprises a means of thermal insulation forming a bearing area for at least partially covering the distal end of said housing, and said accessory comprises a connecting means integrally connecting said thermal insulation means to the base.

Le moyen d'isolation thermique est donc intégré à l'accessoire qui est lui-même démontable du boîtier. Le moyen d'isolation thermique n'est pas en contact direct avec le boîtier ce qui permet de supprimer ou au moins de limiter la conduction thermique entre le boîtier chauffé et le moyen d'isolation thermique. La zone d'appui qui se trouve du coté opposé au boîtier est maintenue à une température ambiante, même pendant l'utilisation de l'appareil, ce qui permet une préhension de la pince dans la zone d'appui sans causer de brûlure ou de sensation désagréable.The thermal insulation means is therefore integrated into the accessory which is itself removable from the housing. The thermal insulation means is not in direct contact with the housing which makes it possible to eliminate or at least limit the thermal conduction between the heated housing and the thermal insulation means. The support zone on the opposite side of the housing is kept at room temperature, even during use of the device, which allows the gripper to be gripped in the bearing zone without causing burns or damage. unpleasant sensation.

De surcroît, le moyen d'isolation thermique est espacé du boîtier d'une distance D, comprise entre 0,5 mm et 4 mm afin de minimiser la conduction thermique. L'air occupant cet espace agit comme isolant thermique.In addition, the thermal insulation means is spaced from the housing by a distance D of between 0.5 mm and 4 mm in order to minimize thermal conduction. The air occupying this space acts as thermal insulation.

Avantageusement, ledit bras comprend un système de verrouillage permettant de bloquer en position assemblée la base de l'au moins un accessoire sur ce bras. Lorsque le système de verrouillage est défait, l'accessoire se trouve dans une position escamotée selon laquelle le coulissement de l'accessoire sur ce bras est autorisé. L'accessoire est donc démontable du boîtier ainsi que le moyen d'isolation thermique. L'utilisateur peut choisir de ne pas les utiliser afin d'avoir une surface lisse sur le boîtier. Ceci permet un multiusage de l'appareil tel que fer à lisser ou fer à boucler.Advantageously, said arm comprises a locking system for locking in the assembled position the base of the at least one accessory on this arm. When the locking system is undone, the accessory is in a retracted position in which the sliding of the accessory on this arm is allowed. The accessory is removable from the housing and the thermal insulation means. The user may choose not to use them in order to have a smooth surface on the housing. This allows a multiuse of the device such as iron to smooth or curling iron.

De surcroît, la base de l'accessoire comprend une barre longitudinale destinée à s'insérer dans la rainure, ledit moyen de liaison étant agencé à l'extrémité discale (ED) lorsque l'accessoire est monté sur le bras. Le moyen d'isolation se trouve alors sur la même extrémité de la barre longitudinale ce qui correspond à l'extrémité distale (ED) du bras.In addition, the base of the accessory comprises a longitudinal bar intended to be inserted in the groove, said connection means being arranged at the end disc (ED) when the accessory is mounted on the arm. The isolation means is then on the same end of the longitudinal bar which corresponds to the distal end (ED) of the arm.

Avantageusement, la rainure est agencée dans une direction parallèle à l'axe longitudinal (X) du bras pour faciliter la mise en place de l'accessoire.Advantageously, the groove is arranged in a direction parallel to the longitudinal axis (X) of the arm to facilitate the introduction of the accessory.

Afin de faciliter la fabrication de l'appareil, l'accessoire, le moyen de liaison et le moyen d'isolation thermique forment une seule pièce.In order to facilitate the manufacture of the apparatus, the accessory, the connecting means and the thermal insulation means form a single piece.

Dans le but de mieux isoler l'accessoire de la chaleur, le moyen d'isolation thermique comprend sur la zone d'appui (ZA) une couverture ayant une conduction thermique inférieure à celle du boîtier. Cette couverture qui est une couche fine peut être constituée d'une matière telle que de la silicone ou du caoutchouc, déposée par surmoulage sur la zone d'appui (ZA).In order to better isolate the accessory from heat, the thermal insulation means comprises on the support zone (ZA) a cover having a thermal conduction lower than that of the housing. This cover which is a thin layer may be made of a material such as silicone or rubber, deposited by overmoulding on the bearing zone (ZA).

Dans un souci de limiter la conduction thermique, il serait préférable de réduire au maximum la surface de contact entre la zone de préhension et le boîtier chauffé lorsqu'un contact est crée par l'appui du moyen d'isolation. Pour ceci, ledit moyen d'isolation thermique présente sur le coté opposé à la zone d'appui (ZA) une protubérance destinée à prendre appui sur le boîtier.For the sake of limiting thermal conduction, it would be preferable to minimize the contact area between the gripping zone and the heated casing when contact is created by the support of the insulating means. For this, said thermal insulation means has on the opposite side to the bearing zone (ZA) a protrusion intended to bear on the housing.

Selon un premier mode de réalisation de l'invention, l'accessoire présente sur la base une série de dents protubérantes par rapport à la plaque chauffante formant un peigne destiné à démêler les cheveux pour faciliter le traitement thermique.According to a first embodiment of the invention, the accessory has on the base a series of protruding teeth relative to the heating plate forming a comb for disentangling the hair to facilitate the heat treatment.

L'appareil comprend au moins deux accessoires comprenant chacun une série de dents de dimension différente pour s'adapter à différents types de cheveux.The apparatus comprises at least two accessories each comprising a series of teeth of different size to accommodate different types of hair.

Selon un deuxième mode de réalisation de l'invention, l'accessoire présente sur la base une série de touffes de soie perpendiculaires à la plaque chauffante formant une brosse destinée à brosser les cheveux durant le traitement thermique pour les rendre plus brillants.According to a second embodiment of the invention, the accessory has on the base a series of silk tufts perpendicular to the heating plate forming a brush for brushing the hair during the heat treatment to make them brighter.

Bien sûr, l'accessoire peut présenter une surface lisse sans peigne ni brosse sur la barre longitudinale pour ceux qui utilisent le lisseur sans peigne ou brosse.Of course, the accessory may have a smooth surface without comb or brush on the longitudinal bar for those who use the straightener without comb or brush.

Selon une caractéristique de l'invention, le bras comprend des moyens de vaporisation de fluide et des moyens de distribution de la vapeur en direction d'une mèche de cheveux. Un tel appareil de coiffure à vapeur présente des zones chaudes qui sont dues à la chambre de vaporisation contenue dans le boîtier ayant une température élevée. L'utilisation d'un moyen d'isolation thermique dans un tel appareil s'avère particulièrement efficace pour une protection thermique pendant l'utilisation de l'appareil.According to one characteristic of the invention, the arm comprises means for vaporizing fluid and means for dispensing steam towards a lock of hair. Such a steam styling apparatus has hot areas which are due to the vaporization chamber contained in the housing having a high temperature. The use of thermal insulation means in such an apparatus is particularly effective for thermal protection during use of the apparatus.

Ces buts sont également atteints avec un accessoire destiné à être monté sur le bras d'un appareil de coiffure du type lisseur de façon détachable, présentant une base destinée à coulisser dans une rainure du bras destinée à recevoir et maintenir ladite base, l'accessoire comprenant un moyen d'isolation thermique formant une zone d'appui destiné à couvrir au moins partiellement l'extrémité distale dudit boîtier.These objects are also achieved with an accessory intended to be mounted on the arm of a hairdressing appliance of the type smoothing detachably, having a base for sliding in a groove of the arm for receiving and holding said base, the accessory comprising thermal insulation means forming a bearing area for at least partially covering the distal end of said housing.

L'invention sera mieux comprise à l'étude des modes de réalisation pris à titre nullement limitatif et illustrés par les dessins annexés dans lesquels :

  • Les figures 1 et 2 sont des vues d'ensemble en perspective d'un appareil de coiffure comprenant un accessoire selon un premier mode de réalisation de l'invention,

Tel qu'illustré en figure 1, l'appareil de coiffure 1 est du type lisseur et comporte deux bras 2, 3 qui sont articulés entre eux à pivotement au moyen d'une liaison pivot 4 du type charnière. Ainsi, les deux bras 2, 3 constituent une pince qui permet soit un écartement angulaire entre ces deux bras 2, 3, soit un rapprochement l'un contre l'autre de ces deux bras 2, 3 pour permettre le pincement de cheveux disposés entre lesdits deux bras 2, 3.As illustrated in figure 1 , the hairstyling apparatus 1 is of the straightener type and comprises two arms 2, 3 which are hinged to each other by means of a pivot connection 4 of the hinge type. Thus, the two arms 2, 3 constitute a clamp which allows either an angular spacing between these two arms 2, 3, or an approximation one against the other of these two arms 2, 3 to allow the pinching of hair arranged between said two arms 2, 3.

Ces bras 2, 3 comprennent chacun un boîtier 21, 31 et un système de chauffe. Outre des moyens électriques chauffants (non illustrés) et des moyens de commande et de régulation thermique (non illustrés), ces systèmes de chauffe comprennent chacun une plaque chauffante 5, 6, prenant la forme d'une surface plane tel qu'illustré sur les figures 1 et 2. Ces surfaces planes chauffantes 51, 61 sont agencées sur les faces internes des bras 2, 3. Ainsi, lors d'un pincement les deux surfaces planes chauffantes sont disposées en regard l'une de l'autre et permettent concomitamment de réaliser un traitement thermique des cheveux, pour effectuer leur lissage.These arms 2, 3 each comprise a housing 21, 31 and a heating system. In addition to electric heating means (not shown) and thermal control and regulation means (not shown), these heating systems each comprise a heating plate 5, 6, taking the form flat surface as illustrated on the figures 1 and 2 . These planar heating surfaces 51, 61 are arranged on the inner faces of the arms 2, 3. Thus, during a nip, the two flat heating surfaces are arranged facing each other and concomitantly allow a heat treatment to be carried out hair, to perform their smoothing.

Comme illustré sur les figures 1 et 2, un des deux bras 2 présente une extrémité proximale (EP) formant une zone de préhension (ZP) et une extrémité distable (ED) intégrant la plaque chauffante 5. Ledit bras 2 comprend un accessoire 9a selon un premier mode de réalisation, l'accessoire étant monté en liaison glissière sur un côté 5a de la surface plane chauffante 51. Comme illustré en figures 3 et 4, la liaison glissière est constituée d'une rainure 23 de guidage agencée sur le bras 2 dans la direction de l'axe longitudinal X dudit bras 2 et, d'une barre longitudinale 91 agencée sur l'accessoire 9a dans la direction de l'axe longitudinal X et qui fait la base de l'accessoire 9a. La barre longitudinale 91 s'engage et coulisse dans les deux sens à l'intérieur de la rainure 23, dans la direction de l'axe longitudinal X, ce qui permet par coulissement dans un sens ou dans l'autre, de monter l'accessoire 9a sur le bras 2 ou, au contraire, de les démonter. Le bras 2 comprend en outre un système de verrouillage permettant de bloquer l'accessoire 9a en position assemblée sur le bras. La construction de la rainure 23 ainsi que le système de verrouillage envisageable sont décrits dans les demandes de brevets FR2993438 et FR1363686 au nom de la demanderesse et ne nécessitent pas une plus ample description ici.As illustrated on figures 1 and 2 one of the two arms 2 has a proximal end (EP) forming a gripping zone (ZP) and a distal end (ED) integrating the heating plate 5. Said arm 2 comprises an accessory 9a according to a first embodiment, the accessory being mounted in sliding connection on a side 5a of the heating plane surface 51. As illustrated in FIG. Figures 3 and 4 , the slide connection consists of a guide groove 23 arranged on the arm 2 in the direction of the longitudinal axis X of said arm 2 and, a longitudinal bar 91 arranged on the accessory 9a in the direction of the longitudinal axis X and which is the base of the accessory 9a. The longitudinal bar 91 engages and slides in both directions inside the groove 23, in the direction of the longitudinal axis X, which allows sliding in one direction or the other, to mount the 9a accessory on the arm 2 or, conversely, disassemble. The arm 2 further comprises a locking system for locking the accessory 9a in the assembled position on the arm. The construction of the groove 23 and the possible locking system are described in the patent applications. FR2993438 and FR1363686 in the name of the plaintiff and do not require further description here.

Tel que visible à la figure 4, l'accessoire 9a comprend à une de ses extrémités un moyen de liaison 11 présenté sous forme d'une bretelle 11 qui est une partie courbée destinée à recouvrir partiellement l'extrémité discale (ED) du bras 2 en suivant son contour extérieur. L'accessoire 9a est relié par ladite bretelle 11 à un moyen d'isolation 10 thermique qui est une pièce sensiblement plate présentant une zone d'appui (ZA) accessible depuis l'extérieur du boitier 21. La taille de cette zone d'appui (ZA) est idéalement supérieure ou égale à la taille du pouce, ce qui permet d'appuyer simplement le pouce sans viser. Par exemple, la largeur de la zone d'appui (ZA) est comprise entre 10 mm et 45 mm. La valeur de surface de la zone d'appui est comprise entre 2cm2 et 16cm2. La zone d'appui (ZA) peut également présenter une surface nervurée 14, comprenant par exemple des lignes en protubérance permettant de faciliter la prise de l'appareil ainsi que de réduire la sensation de brûlure.As visible at figure 4 , the accessory 9a comprises at one of its ends a connecting means 11 in the form of a shoulder strap 11 which is a curved portion intended to partially cover the disc end (ED) of the arm 2 following its outer contour. The accessory 9a is connected by said ramp 11 to a thermal insulation means 10 which is a substantially flat piece having a bearing zone (ZA) accessible from outside the housing 21. The size of this support zone (ZA) is ideally greater than or equal to the size of the thumb, which allows to simply press the thumb without aiming. For example, the width of the bearing zone (ZA) is between 10 mm and 45 mm. The surface value of the support zone is between 2cm 2 and 16cm 2 . The bearing zone (ZA) may also have a ribbed surface 14, for example comprising protruding lines making it easier to grip the apparatus and to reduce the burning sensation.

Le moyen d'isolation 10 comprend sur le coté opposé de la zone d'appui (ZA) un gaudron 13 qui est une ligne en protubérance 13. Ledit gaudron 13 permet d'assurer le contact unique entre le boîtier chaud et la zone d'appui (ZA) lorsque le moyen d'isolation 10 est sollicité. Tout le reste du moyen d'isolation 10 reste écarté du boîtier à une distance minimale D, comprise entre 0,5 mm et 4 mm.. Ceci permet de minimiser le contact de matière ainsi que la conduction thermique, la zone d'appui (ZA) reste donc peu chauffée.The insulating means 10 comprises on the opposite side of the bearing zone (ZA) a gaudron 13 which is a protruding line 13. Said gaudron 13 makes it possible to ensure the single contact between the hot housing and the zone of support (ZA) when the insulation means 10 is biased. The remainder of the insulation means 10 remains spaced from the housing at a minimum distance D of between 0.5 mm and 4 mm. This makes it possible to minimize the contact of material as well as the thermal conduction, the bearing zone ( ZA) therefore remains little heated.

Dans la sélection de la matière, ladite bretelle 11 peut être réalisée en un matériau déformable tel que du plastique, ce qui permet sa déformation et sa remise en état avec ou sans effort d'appui sur le moyen d'isolation. La bretelle 11 peut aussi être rigide, auquel cas un gaudron n'est plus nécessaire puisqu'aucun contact n'est possible entre le moyen d'isolation 10 et le boîtier 21. Selon un exemple de l'invention, il s'agit d'une pièce monobloc faite en plastique qui comprend l'accessoire 9a, le moyen de liaison 11 et le moyen d'isolation 10. La pièce monobloc 9a peut être en polyamide (PA) chargé ou non en fibres de verre, ou encore en polybutylène téréphtalate (PBT) chargé ou non chargé, ou en polysulfone (PSU).In the selection of the material, said strap 11 may be made of a deformable material such as plastic, which allows its deformation and restoration with or without support effort on the insulation means. The strap 11 can also be rigid, in which case a gaudron is no longer necessary since no contact is possible between the insulation means 10 and the housing 21. According to an example of the invention, it is a question of a one-piece piece made of plastic which comprises the accessory 9a, the connecting means 11 and the insulating means 10. The one-piece piece 9a may be made of polyamide (PA), which may or may not be filled with fiberglass, or else polybutylene charged or uncharged terephthalate (PBT), or polysulfone (PSU).

Selon une variante non illustrée, le moyen d'isolation 10 comprend sur la zone d'appui (ZA) une couche à conduction thermique faible. Il est possible d'intégrer un surmoulage en silicone ou en caoutchouc sur la zone d'appui (ZA) pour mieux isoler l'accessoire de la chaleur. De préférence, la couverture surmoulée possède une conduction thermique inférieure à celle du boîtier 21, de l'ordre de 0.16 W/(m . K). De plus, la silicone ou le caoutchouc permet un toucher agréable et une meilleure résistance à la température pour effectuer le surmoulage.According to a variant not illustrated, the insulating means 10 comprises on the support zone (ZA) a low thermal conduction layer. It is possible to incorporate a silicone or rubber over-molding on the support zone (ZA) to better insulate the accessory from heat. Preferably, the overmolded cover has a thermal conduction lower than that of the housing 21, of the order of 0.16 W / (m.K). In addition, the silicone or the rubber allows a pleasant touch and a better resistance to the temperature to perform the overmolding.

Tel que visible aux figures 1, 2, 4 et 5, et selon un premier mode de réalisation de l'appareil, l'accessoire 9a comprend une série de dents 94 protubérante depuis la barre longitudinale 91 formant un peigne permettant de démêler et de coiffer les cheveux durant leur lissage et de répartir de façon régulière la mèche sur la plaque. Les dents 94 sont préférablement agencées perpendiculaires à la plaque chauffante 5 et peuvent se loger dans une cavité longitudinale 32 située dans le bras 3 en regard.As visible to figures 1 , 2 , 4 and 5 , and according to a first embodiment of the apparatus, the accessory 9a comprises a series of teeth 94 protruding from the longitudinal bar 91 forming a comb for detangling and styling the hair during their smoothing and to distribute regular wick on the plate. The teeth 94 are preferably arranged perpendicular to the heating plate 5 and can be housed in a longitudinal cavity 32 located in the arm 3 opposite.

Alternativement, l'appareil peut comprendre au moins deux accessoires du type peigne comprenant chacun une série de dents à dimension différente. Par exemple des peignes avec des dents de différente hauteur, d'épaisseur ou de forme etc.Alternatively, the apparatus may comprise at least two comb-type accessories each comprising a series of differently sized teeth. For example combs with teeth of different height, thickness or shape etc.

Selon un deuxième mode de réalisation et tel qu'illustré à la figure 7, un accessoire 9c comprend une série de touffes de soie 93 telles que des poils durs ou des poils souples, formant une brosse permettant de brosser les cheveux durant le traitement pour les rendre plus brillants.According to a second embodiment and as illustrated in figure 7 9c a accessory includes a series of tufts of silk 93 such as bristles or soft bristles, forming a brush to brush the hair during treatment to make them brighter.

Selon un troisième mode de réalisation tel que visible à la figure 6, un accessoire 9b comprend uniquement la barre longitudinale 91, le moyen d'isolation 10 et la bretelle 11, sans aucune dent de peigne ou de brosse.According to a third embodiment as visible in the figure 6 , an accessory 9b includes only the longitudinal bar 91, the insulating means 10 and the strap 11, without any comb or brush tooth.

On peut également proposer plusieurs types d'accessoire susmentionnés aux utilisateurs pour qu'ils puissent les changer en cas de nécessité.Several types of aforementioned accessories can also be proposed to the users so that they can change them if necessary.

Dans le cas où l'appareil est équipé d'un système de vaporisation tel qu'illustré à la figure 8, l'appareil 1 comprend une base 1000 avec un réservoir de fluide 19, une unité portable 100 comprenant des moyens de vaporisation 7' du fluide, des moyens de distribution de la vapeur 22 à destination des cheveux, un cordon 24 comportant au moins une canalisation destinée au passage de fluide et agencée entre le réservoir de fluide 19 et les moyens de vaporisation 7', l'unité portable 100 comprend des plaques chauffantes 5, 6 destinées à venir en contact avec les cheveux et les moyens de vaporisation du fluide 7' sont prévus dans l'unité portable 100. La base est déportée de l'unité portable, et posable sur un plan de travail. La configuration d'un tel appareil est décrite dans le brevet 2 967 017 au nom de la demanderesse et ne nécessite pas une plus ample description.In the case where the apparatus is equipped with a vaporization system as illustrated in figure 8 the apparatus 1 comprises a base 1000 with a fluid reservoir 19, a portable unit 100 comprising means for vaporization 7 'of the fluid, means for dispensing the vapor 22 to the hair, a cord 24 comprising at least one pipe for the fluid passage and arranged between the fluid reservoir 19 and the vaporization means 7 ', the portable unit 100 comprises heating plates 5, 6 intended to come into contact with the hair and the means for vaporizing the fluid 7 are provided in the portable unit 100. The base is remote from the portable unit, and posable on a work plan. The configuration of such an apparatus is described in the patent 2,967,017 in the name of the plaintiff and does not require further description.

Selon cette configuration, le bras 2 comprend des moyens de distribution de la vapeur 22 sous forme d'une série d'orifices destinées à la distribution de vapeur, tel que visible à la figure 3. De préférence, l'accessoire 9a, 9b, 9c est agencé entre la plaque chauffante 5 et les orifices 22.According to this configuration, the arm 2 comprises means for dispensing the vapor 22 in the form of a series of orifices intended for the vapor distribution, as visible in figure 3 .
