Description

La présente invention concerne le domaine technique des appareils à main utilisés pour la coiffure ou la mise en forme des cheveux. Dans une application préférée mais non exclusive, l'invention se rapporte au domaine des appareils électriques à main utilisés pour le séchage et/ou la mise en forme des cheveux au moyen notamment d'un flux d'air chaud ou par application de chaleur par contact tels que les sèche-cheveux électriques à main, les brosses soufflantes ou encore les fers à lisser, à boucler ou à friser sans que cette liste ne soit limitative ou exhaustive.The present invention relates to the technical field of hand-held devices used for hairdressing or shaping hair. In a preferred but not exclusive application, the invention relates to the field of electrical hand-held apparatuses used for drying and / or shaping hair by means, in particular, of a hot air flow or by application of heat by means of contact such as hand-held electric hairdryers, blower brushes or even straightening, curling or curling irons without this list being exhaustive or exhaustive.

Lors de la réalisation d'une coiffure, il peut être souhaitable d'appliquer, au fur et à mesure du traitement des mèches, un produit cosmétique sur les cheveux. À cet effet, un brevet FR 2 136 410 a proposé un peigne soufflant dont le manche comprend un ventilateur électrique adapté pour souffler de l'air en direction d'une zone de traitement des cheveux définie par le peigne. Le manche de ce peigne soufflant comprend également un réservoir de liquide cosmétique sous pression raccordé par un circuit d'alimentation à un spray disposé dans la zone de traitement des cheveux. Selon ce document, le manche comprend également une pompe à piston actionnée par un bouton poussoir permettant à l'utilisateur de déclencher, par une pression du doigt sur le bouton, une pulvérisation de liquide par la buse au niveau de la zone de traitement. Un tel système permet effectivement d'appliquer facilement un produit sur les cheveux en limitant les risques de gaspillage dudit produit cosmétique. Toutefois, ce système ne permet pas de doser de manière précise la quantité de produit appliqué, et impose à l'utilisateur de presser le bouton poussoir pour obtenir la distribution de produits ce qui n'est pas toujours aisé selon la partie de la chevelure à traiter. En outre, le dépôt de cosmétique n'est ni constant ni homogène. De plus, l'utilisateur doit, pour traiter toute sa chevelure, presser de nombreuses fois le bouton poussoir ce qui impose un effort relativement important engendrant un certain inconfort.When making a hairstyle, it may be desirable to apply, as and when the treatment of locks, a cosmetic product on the hair. For this purpose, a patent FR 2 136 410 proposed a blower comb whose handle includes an electric fan adapted to blow air towards a hair treatment area defined by the comb. The handle of this blowing comb also comprises a tank of cosmetic liquid under pressure connected by a supply circuit to a spray disposed in the hair treatment area. According to this document, the handle also comprises a piston pump actuated by a push button allowing the user to trigger, by pressing the finger on the button, a liquid spray through the nozzle at the treatment area. Such a system effectively makes it possible to easily apply a product to the hair by limiting the risks of wasting of said cosmetic product. However, this system does not allow precise dosing the amount of product applied, and requires the user to press the push button to obtain the distribution of products which is not always easy depending on the part of the hair to treat. In addition, the cosmetic deposit is neither constant nor homogeneous. In addition, the user must, to treat all his hair, press many times the push button which imposes a relatively large effort causing some discomfort.

Afin de permettre une application automatique d'un produit cosmétique sur les cheveux, un brevet EP 1071352 a proposé un sèche-cheveux comprenant un accessoire pourvu de dents pour la mise en forme des cheveux dont les dents comprennent des moyens de distribution de produits cosmétiques activés par la chaleur ou l'humidité. Selon ce document, les dents forment une cavité à l'intérieur de laquelle est disposée une quantité donnée de produits cosmétiques. Un tel sèche-cheveux permet effectivement l'application d'un produit cosmétique de manière automatique en faible quantité sans que l'utilisateur n'ait à se préoccuper de la quantité de produit appliquée mais présente l'inconvénient de ne pas pouvoir garantir une application uniforme du produit cosmétique sur les cheveux dans la mesure où cette application est tributaire de la chaleur et/ou de l'humidité qui est susceptible de varier fortement selon les zones de la chevelure traitée.In order to allow an automatic application of a cosmetic product to the hair, a patent EP 1071352 proposed a hair dryer comprising an accessory provided with teeth for shaping the hair whose teeth comprise means of dispensing cosmetics activated by heat or moisture. According to this document, the teeth form a cavity inside which is disposed a given amount of cosmetics. Such a hair dryer effectively allows the application of a cosmetic product automatically in small quantities without the user having to worry about the amount of product applied but has the disadvantage of not being able to guarantee an application uniform of the cosmetic product on the hair insofar as this application is dependent on heat and / or moisture that is likely to vary greatly depending on the areas of the treated hair.

Il est connu de JP2005152149 un appareil d'application de cosmétique sur cheveux contenant un réservoir de fluide, une pompe à la sortie du réservoir, alimentant un canal de distribution de liquide via un élément présentant des ports d'alimentation de liquide, élément sur lequel vient pincer un peigne, le pincement actionnant indirectement la pompe.It is known to JP2005152149 a hair cosmetic application apparatus containing a fluid reservoir, a pump at the outlet of the reservoir, supplying a liquid distribution channel via an element having liquid supply ports, which element is clamped on a comb, the pinch indirectly operating the pump.

Il est donc apparu le besoin d'un appareil de coiffure à main qui permette une distribution automatique d'un produit cosmétique sans que cette distribution ne doive faire l'objet d'une action spécifique de déclenchement par l'utilisateur, tout en évitant que cette application ne soit tributaire des conditions de chaleur et d'humidité au niveau du point d'application.It has therefore appeared the need for a hand-held hairdressing device that allows an automatic dispensing of a cosmetic product without this distribution having to be the subject of a specific action of triggering by the user, while avoiding that this application is dependent on the heat and humidity conditions at the point of application.

Afin d'atteindre cet objectif l'invention concerne un appareil de coiffure selon la revendication 1.In order to achieve this object the invention relates to a hairdressing apparatus according to claim 1.

Dans un mode particulier, l'invention concerne un appareil de coiffure à main comprenant des moyens de mise en forme ou coiffure comprenant au moins une zone de traitement des cheveux, des moyens de distribution d'un produit cosmétique comprenant des moyens d'application du produit situés à proximité ou dans la zone de traitement des cheveux, un circuit d'alimentation des moyens d'application à partir d'un réservoir de produit cosmétique, comprenant au moins une pompe, où les moyens de mise en forme sont, en partie au moins, mobiles, et comprennent au moins un rouleau mobile en rotation, et où la ou chaque pompe est manoeuvrée par le mouvement du rouleau (M) mobile en rotation.In a particular embodiment, the invention relates to a hand-held hairdressing appliance comprising shaping means or hairstyle comprising at least one hair treatment zone, means for dispensing a cosmetic product. comprising means for applying the product located near or in the hair treatment zone, a supply circuit for the application means from a cosmetic product reservoir, comprising at least one pump, wherein the means for shaping are at least partly mobile, and comprise at least one rotating roller, and wherein the or each pump is operated by the movement of the roller (M) rotatable.

La mise en oeuvre de la pompe, qui est adaptée pour être manoeuvrée automatiquement par le mouvement des moyens de mise en forme, permet d'asservir la quantité de produit distribuée à l'étendue de la zone de la chevelure traitée et par exemple à la longueur de chaque mèche de cheveux traitée de sorte que cette quantité est parfaitement dosée. De plus, dans la mesure où l'apport de produit cosmétique résulte d'une action mécanique sur la pompe, la quantité de produit distribuée est indépendante des conditions de chaleur et humidité de la chevelure ou encore de l'appareil à main selon l'invention. L'appareil selon l'invention permet par ailleurs de distribuer ou d'appliquer des quantités de produit cosmétique supérieures à celles susceptibles d'être appliquées au moyen d'un système tel que prévu par le brevet EP 1 071352 .The implementation of the pump, which is adapted to be operated automatically by the movement of the shaping means, allows to enslave the amount of product distributed to the extent of the treated hair area and for example to the length of each strand of hair treated so that this quantity is perfectly dosed. In addition, insofar as the supply of cosmetic product results from a mechanical action on the pump, the amount of product dispensed is independent of the heat and humidity conditions of the hair or the hand-held device according to the invention. invention. The apparatus according to the invention also makes it possible to distribute or apply amounts of cosmetic product greater than those which can be applied by means of a system as provided for by the patent. EP 1 071352 .

Dans le cadre de la présente invention, il faut entendre par produit cosmétique un produit comprenant un ou plusieurs principes actifs à usage capillaire et notamment un produit tel que défini par la directive européenne CE 93/35 du 14 juin 1993. À cet égard, de l'eau sous forme liquide ou gazeuse qui ne contient aucun additif à usage capillaire ne constitue pas un produit cosmétique au sens de l'invention.In the context of the present invention, the term "cosmetic product" is intended to mean a product comprising one or more active principles for capillary use and in particular a product as defined by the European Directive EC 93/35 of 14 June 1993. In this regard, water in liquid or gaseous form which does not contain any additive for capillary use does not constitute a cosmetic product within the meaning of the invention.

Selon l'invention, la pompe peut être réalisée de toutes manières appropriées et, par exemple, sous la forme d'une pompe à piston dont le mouvement alternatif du piston est commandé par le mouvement des moyens de mise en forme des cheveux.According to the invention, the pump can be made in any suitable manner and, for example, in the form of a piston pump whose reciprocating movement of the piston is controlled by the movement of the hair shaping means.

Selon une forme préférée, mais non exclusive, d'un appareil de coiffure à main conforme à l'invention, chaque pompe comprend :

  • un corps souple qui définit une chambre de pompage,
  • et au moins un organe presseur manoeuvré par le mouvement des moyens de mise en forme ou coiffure et adapté pour presser de manière intermittente ou continue le corps souple.
According to a preferred, but not exclusive, form of a hand-held hairdressing appliance according to the invention, each pump comprises:
  • a flexible body which defines a pumping chamber,
  • and at least one pressing member operated by the movement of the shaping means or hairstyle and adapted to intermittently or continuously press the flexible body.

Une telle forme de réalisation permet une fabrication de la pompe à moindre coût. Ce faible coût de fabrication permet notamment d'envisager un changement régulier du corps souple qui peut alors être considéré comme un consommable contribuant ainsi à une bonne hygiène de l'appareil selon l'invention.Such an embodiment allows a manufacture of the pump at lower cost. This low manufacturing cost makes it possible in particular to envisage a regular change of the flexible body which can then be considered as a consumable thus contributing to good hygiene of the apparatus according to the invention.

Selon une variante de la forme préférée de réalisation, le corps souple est élastiquement déformable.According to a variant of the preferred embodiment, the flexible body is elastically deformable.

Ainsi, la contrainte de l'organe presseur est mise à profit pour expulser le produit hors de la chambre de pompage tandis que l'élasticité du corps est mise à profit pour aspirer le produit dans la chambre de pompage lorsque l'organe presseur n'exerce plus de contrainte sur le corps souple. Cette déformation réversible du corps de la pompe permet de réaliser cette dernière et son mécanisme de manoeuvre à moindre coût.Thus, the constraint of the pressure member is used to expel the product from the pumping chamber while the elasticity of the body is used to suck the product into the pumping chamber when the pressure member n ' exerts more stress on the flexible body. This reversible deformation of the body of the pump makes it possible to realize the latter and its operating mechanism at lower cost.

Selon une caractéristique de cette variante, les moyens de distribution comprennent entre la pompe et les moyens d'application, au moins un clapet anti-retour adapté pour autoriser une circulation de produit cosmétique de la pompe vers les moyens d'application. Selon l'invention ce clapet anti-retour peut être placé entre la sortie de la pompe et les moyens d'application. Il peut également être intégré aux moyens d'application qui pourront par exemple comprendre une ou plusieurs buses chacune réalisée sous la forme de deux lèvres élastiquement déformables qui s'écartent lors de l'expulsion du produit et se resserrent l'une contre l'autre ensuite. Les moyens d'application peuvent être un tuyau de silicone ou matériau similaire dont les buses sont des fentes étanches réparties axialement uniformément pour une distribution du cosmétique aussi homogène que possible. Un tel clapet anti-retour étanche de distribution peut également être intégré à la sortie de la pompe et notamment au corps constitutif de cette dernière.According to a characteristic of this variant, the dispensing means comprise between the pump and the application means, at least one non-return valve adapted to allow a flow of cosmetic product from the pump to the application means. According to the invention this non-return valve can be placed between the outlet of the pump and the application means. It can also be integrated in the application means which may for example comprise one or more nozzles each made in the form of two elastically deformable lips that deviate during the expulsion of the product and then tighten against each other. The application means may be a silicone hose or similar material whose nozzles are airtight slots distributed axially uniformly for a distribution of the cosmetic as homogeneous as possible. Such a sealed non-return valve distribution can also be integrated in the output of the pump and in particular the body of the latter.

Selon une variante de la forme préférée de réalisation de l'invention, les moyens de distribution comprennent entre le réservoir de produit cosmétique et la pompe au moins un clapet anti-retour adapté pour autoriser une circulation de produit cosmétique du réservoir vers la pompe. Ce clapet anti-retour d'aspiration peut être situé sur le circuit entre la pompe et le réservoir. Ce clapet anti-retour peut également être intégré au réservoir ou encore intégré à l'entrée de la pompe et notamment au corps constitutif de cette dernière.According to a variant of the preferred embodiment of the invention, the dispensing means comprise between the cosmetic product tank and the pump at least one non-return valve adapted to allow a flow of cosmetic product from the reservoir to the pump. This suction check valve can be located on the circuit between the pump and the tank. This non-return valve can also be integrated in the tank or integrated in the pump inlet and in particular the body of the latter.

Selon l'invention, le corps souple de chaque pompe peut être formé par un réservoir contenant une quantité suffisante de produit pour permettre la distribution de plusieurs doses de produit et notamment contenir assez de produit pour assurer une séquence complète de traitement. Dans ce cas, le corps souple peut être un élément jetable susceptible d'être remplacé à chaque utilisation de ce corps accessoire. Le corps souple de la pompe peut également former un ensemble monobloc avec le circuit d'alimentation et la buse de distribution, ensemble également susceptible d'être remplacé à chaque fois que le réservoir est vide.According to the invention, the flexible body of each pump may be formed by a reservoir containing a sufficient quantity of product to allow the distribution of several doses of product and in particular contain enough product to ensure a complete sequence of treatment. In this case, the flexible body may be a disposable element that can be replaced with each use of this accessory body. The flexible body of the pump can also form a one-piece assembly with the supply circuit and the dispensing nozzle, together also likely to be replaced each time the tank is empty.

Toutefois un tel mode de réalisation n'est pas nécessaire à l'invention. Ainsi, selon une caractéristique de l'invention, les moyens de distribution comprennent un réservoir de produit cosmétique situé en amont de chaque pompe. Ce réservoir distinct de la pompe permet d'augmenter l'autonomie de l'appareil selon l'invention.However, such an embodiment is not necessary for the invention. Thus, according to one characteristic of the invention, the dispensing means comprise a cosmetic product reservoir located upstream of each pump. This reservoir separate from the pump makes it possible to increase the autonomy of the apparatus according to the invention.

Ainsi, selon l'invention le réservoir peut être amovible ou au contraire être fixe. Le réservoir peut être un sachet souple mais non élastique, et préférentiellement sans évent. Le sachet n'a pas de résistance élastique et permet de transmettre la pression atmosphérique au cosmétique contenu. Un tel réservoir est peu cher.Thus, according to the invention the tank can be removable or on the contrary be fixed. The reservoir may be a flexible bag but not elastic, and preferably without vent. The bag does not have an elastic resistance and makes it possible to transmit the atmospheric pressure to the cosmetic content. Such a tank is cheap.

Lorsque l'appareil selon l'invention comprend un réservoir, les moyens de distribution peuvent comprendre au moins un orifice de remplissage du réservoir. Un tel orifice peut être mis à profit pour remplir le réservoir notamment lorsque ce dernier n'est pas amovible.When the apparatus according to the invention comprises a reservoir, the dispensing means may comprise at least one filling orifice of the reservoir. Such an orifice can be used to fill the tank, especially when the latter is not removable.

Selon l'invention, l'appareil de coiffure à main peut être de diverses natures et de manière préférée l'appareil conforme à l'invention est un appareil de coiffure électrique à main. Ainsi, l'appareil de coiffure à main selon l'invention peut comprendre des moyens électriques de chauffage de la zone de traitement. L'appareil de coiffure à main selon l'invention peut aussi comprendre des moyens électriques de soufflage d'air vers la zone de traitement.According to the invention, the hand-held hairdressing apparatus can be of various types and, preferably, the apparatus according to the invention is an electric hand-held hairdressing appliance. Thus, the hand-held hairdressing apparatus according to the invention may comprise electric means for heating the treatment zone. The hand-held hairdressing appliance according to the invention may also comprise electrical means for blowing air towards the treatment zone.

L'appareil de coiffure selon l'invention peut, par exemple, être conçu pour permettre une mise en forme ou un lissage avec un chauffage des cheveux par contact et former notamment un fer à friser ou un lisseur. Ainsi, dans une variante de réalisation, l'appareil de coiffure à main comprend deux mâchoires, première et deuxième, qui sont articulées entre elles par une charnière, pour être mobiles entre une position ouverte et une position fermée, qui comprennent des surfaces de travail formant les moyens de mise en forme des cheveux et définissant la zone de traitement de cheveux en position fermée des mâchoires. Chaque pompe est alors manoeuvrée par les mouvements des mâchoires ou des surfaces de travail l'une par rapport à l'autre.The hairdressing appliance according to the invention may, for example, be designed to allow shaping or smoothing with heating of the hair by contact and in particular to form a curling iron or a straightener. Thus, in an alternative embodiment, the hand-held hairdressing apparatus comprises two jaws, first and second, which are articulated together by a hinge, to be movable between an open position and a closed position, which comprise working surfaces. forming the hair shaping means and defining the hair treatment area in the closed position of the jaws. Each pump is then maneuvered by the movements of the jaws or working surfaces relative to each other.

Dans une telle configuration de lisseur ou fer à friser: un organe longitudinal presseur est agencé sur la mâchoire en regard de la mâchoire comportant les moyens de distribution de fluide. Cet organe longitudinal presseur est agencé en regard des moyens de distribution de cosmétique et pour venir en contact contre ces moyens en position fermée de l'appareil. L'organe peut être une tige rigide parallélépipédique qui viendra appuyer sur les moyens de distribution. L'organe peut additionnellement comporter une fine couche de mousse sur sa surface externe. Cette couche permet une répartition uniforme du cosmétique sur les deux faces d'application destinées à presser les cheveux pendant la distribution de fluide.In such a configuration of straightener or curling iron: a longitudinal pressure member is arranged on the jaw facing the jaw comprising the fluid distribution means. This longitudinal pressure member is arranged facing the cosmetic dispensing means and to come into contact with these means in the closed position of the apparatus. The organ can be a rigid parallelepipedic rod which will come to support the means of distribution. The member may additionally have a thin layer of foam on its outer surface. This layer allows a uniform distribution of the cosmetic on the two application faces intended to press the hair during fluid distribution.

L'actionnement de la pompe peut être annihilé au choix de l'utilisateur : dans ce but, s'il s'agit d'une version lisseur, l'organe presseur agencé sur la mâchoire en regard de la mâchoire contenant le sachet peut être déplacé et levé au travers du boitier de la mâchoire par l'utilisateur qui souhaite utiliser son appareil sans l'option application de cosmétique.The actuation of the pump can be annihilated at the choice of the user: for this purpose, if it is a smoothing version, the pressing member arranged on the jaw opposite the jaw containing the bag can be moved and lifted through the case of the jaw by the user who wishes to use his device without the cosmetic application option.

Dans le cadre de cette variante, l'appareil de coiffure peut comprendre des moyens électriques de chauffage associés à l'une au moins des surfaces de travail. Toujours dans le cadre de cette variante, l'appareil de coiffure à main peut comprendre des moyens de manoeuvre de chaque pompe qui sont adaptés pour manoeuvrer chaque pompe après un nombre prédéterminé de mouvements consécutifs d'ouverture et de fermetures des mâchoires. La mise en oeuvre de tels moyens de manoeuvre permet d'éviter que la pompe ne soit actionnée à chaque cycle de fermeture ouverture de manière à permettre un meilleur dosage du produit cosmétique. Un tel mode de réalisation est particulièrement adapté à des moyens d'application comprenant un feutre ou un matériau poreux au travers duquel le produit cosmétique est distribué.In the context of this variant, the hairdressing appliance may comprise electric heating means associated with at least one of the working surfaces. Still in the context of this variant, the hand-held hairdressing apparatus may include means for operating each pump which are adapted to maneuver each pump after a predetermined number of consecutive movements of opening and closing of the jaws. The implementation of such operating means prevents the pump is actuated at each opening closing cycle so as to allow a better dosage of the cosmetic product. Such an embodiment is particularly suitable for application means comprising a felt or a porous material through which the cosmetic product is dispensed.

Enfin, dans le cadre de cette variante, les surfaces de travail peuvent être planes ou courbes en étant de formes sensiblement complémentaires l'une de l'autre.Finally, in the context of this variant, the working surfaces can be flat or curved by being substantially complementary forms of one another.

Selon une autre variante de l'invention, les moyens de mise en forme ou coiffure comprennent au moins un rouleau mobile en rotation. Un tel rouleau sera de préférence mobile en rotation sur lui-même selon son axe longitudinal. Ainsi, les moyens de mise en forme ou coiffure peuvent comprendre un rouleau lisse, un rouleau avec une surface extérieure cannelée ou texturée, ou encore un rouleau avec des poils formant une brosse rotative. Une telle brosse pourra alors être associée à un système de ventilateur électrique pour former une brosse soufflante. La rotation du rouleau des moyens de mise en forme pourra être mise à profit pour entrainer ou actionner la pompe.According to another variant of the invention, the forming means or hairstyle comprise at least one rotating roller. Such a roll will preferably be rotatable on itself along its longitudinal axis. Thus, the shaping means or hairstyle may comprise a smooth roller, a roller with a grooved or textured outer surface, or a roller with bristles forming a rotating brush. Such a brush can then be associated with a system of electric fan to form a blower brush. The rotation of the roll forming means can be used to drive or actuate the pump.

Bien entendu, les différentes caractéristiques, variantes et formes de réalisation de l'invention peuvent être associées les unes avec les autres selon diverses combinaisons dans la mesure où elles ne sont pas incompatibles ou exclusives les unes des autres.Of course, the various features, variations and embodiments of the invention may be associated with each other in various combinations to the extent that they are not incompatible or exclusive of each other.

Un appareil de coiffure à main selon l'invention est susceptible d'être réalisé de différentes manières en fonction de sa finalité et du type de traitement qu'il est susceptible d'appliquer aux cheveux.A hand-held hairdressing appliance according to the invention can be made in different ways depending on its purpose and the type of treatment that it is likely to apply to the hair.

Ainsi, l'appareil de coiffure selon l'invention peut constituer un lisseur, tel qu'illustré aux figures 1 et 2, désigné dans son ensemble par la référence A. L'appareil de coiffure A comprend une première mâchoire allongée 1 de forme générale parallélépipédique et s'étendant selon un axe longitudinal L. L'appareil de coiffure A comprend aussi une deuxième mâchoire 2 qui est également allongée et s'étend selon un axe longitudinal L'. Les mâchoires 1 et 2 sont liées à proximité de l'une de leur extrémité par une charnière ou liaison pivot 4 d'axe Ω. Ainsi, les mâchoires 1 et 2 sont articulées entre elles et mobiles entre une position ouverte 0 telle qu'illustrée à la figure 1, et une position fermée non représentée.Thus, the hairdressing appliance according to the invention can constitute a straightener, as illustrated in FIG. Figures 1 and 2 The hairstyling apparatus A comprises a first elongate jaw 1 of generally parallelepipedal shape and extending along a longitudinal axis L. The hairstyling apparatus A also comprises a second jaw 2 which is also elongated and extends along a longitudinal axis L '. The jaws 1 and 2 are connected near one of their ends by a hinge or pivot link 4 axis Ω. Thus, the jaws 1 and 2 are hinged together and movable between an open position 0 as illustrated in FIG. figure 1 , and a closed position not shown.

L'appareil de coiffure A comprend des moyens M de mise en forme des cheveux qui selon l'exemple illustré comprennent pour, chaque mâchoire 1 et 2, une surface de travail, respectivement S1, S2, à proximité d'une extrémité de la mâchoire correspondante opposée à la liaison 4. Les surfaces de travail S1, S2 sont situées en regard l'une de l'autre et s'étendent sur une partie seulement de la longueur des mâchoires 1 et 2, de manière à définir en position fermée une zone Z de traitement des cheveux. Les surfaces de travail S1, S2 constituent, en combinaison avec les mâchoires 1 et 2 qui les portent, des moyens mobiles de mise en forme M, au sens de l'invention.The hairstyling apparatus A comprises means M for shaping the hair which, according to the illustrated example, comprise, for each jaw 1 and 2, a working surface, respectively S 1 , S 2 , close to an end of jaw corresponding to the connection 4. The working surfaces S 1 , S 2 are located opposite one another and extend over only a portion of the length of the jaws 1 and 2, so as to define in position closed a Z zone of hair treatment. The working surfaces S 1 , S 2 constitute, in combination with the jaws 1 and 2 which carry them, mobile shaping means M, within the meaning of the invention.

Selon l'exemple illustré, les deux mâchoires 1 et 2 contribuent en outre à définir par leurs régions de leur dos P1, P2 situées entre les surfaces de travail S1 et S2 et l'articulation 4 en charnière ou liaison pivot des moyens de préhension P de l'appareil de coiffure A. Ainsi, compte tenu de l'articulation des mâchoires 1 et 2 entre elles, la deuxième surface de travail S2 est mobile par rapport à la partie P1 des moyens de préhension formée par la première mâchoire 1 tandis que la première surface de travail S1 est mobile par rapport à la partie P2 des moyens de préhension formée par la deuxième mâchoire 2 de sorte que les moyens M de mise en forme sont en partie mobiles par rapport à une partie des moyens de préhension P.According to the illustrated example, the two jaws 1 and 2 further contribute to define by their regions their backs P 1 , P 2 located between the working surfaces S 1 and S 2 and the hinged joint 4 or pivot link gripping means P of the hairstyling apparatus A. Thus, taking into account the articulation of the jaws 1 and 2 between them, the second working surface S 2 is movable relative to the portion P 1 of the gripping means formed by the first jaw 1 while the first working surface S 1 is movable relative to the portion P 2 of the gripping means formed by the second jaw 2 so that the forming means M are partially movable relative to a part of the gripping means P.

Chaque surface de travail S1 et S2 présente, selon l'exemple illustré, une forme générale rectangulaire et se trouve réalisée en un matériau thermiquement conducteur ayant un état de surface adapté pour être placé au contact de cheveux sans risque de les détériorer. Ainsi, chaque surface de travail S1, S2 pourrait par exemple être lisse en étant polie ou éventuellement recouverte d'un émail, d'un matériau céramique, d'un matériau polymère ou d'un émail (par exemple à faible coefficient de friction) ou encore d'une couche de verre.Each working surface S 1 and S 2 has, according to the example shown, a generally rectangular shape and is made of a thermally conductive material having a surface state adapted to be placed in contact with hair without the risk of damaging them. Thus, each working surface S 1 , S 2 could for example be smooth by being polished or possibly covered with an enamel, a ceramic material, a polymer material or an enamel (for example with a low friction) or a layer of glass.

Les surfaces de travail S1 et S2 sont par exemple formées par des plaques de lissage respectivement première 5 et deuxième 6. Les plaques de lissage 5 et 6 sont chacune associées à des moyens électriques de chauffage 7 en contact avec la surface arrière de la plaque correspondante, située à l'opposé de la surface de travail S1, S2, comme le montre la figure 2. Les moyens électriques de chauffage peuvent être réalisés de toute manière appropriée telle que par exemple sous la forme d'un élément chauffant résistif à CTP ou à émission infrarouge. Les moyens électriques de chauffage 7 sont donc situés à l'intérieur des première 1 et deuxième 2 mâchoires. Les moyens de chauffage sont reliés par un cordon 10 à une alimentation électrique telle qu'un réseau de distribution d'électricité. Le cordon 10 alimente des moyens de commande 11 permettant une sélection, par un utilisateur, d'une température de consigne. Bien entendu, l'alimentation électrique de l'appareil de coiffure A pourrait également être assurée par des batteries ou des piles disposées à l'intérieur de l'une et/ou l'autre des mâchoires 1 et 2. De même, les moyens de chauffage pourraient également être conçus pour maintenir une température cible prédéterminée de manière automatique Les modes de réalisation des moyens de chauffage et de l'éventuelle unité de commande sont bien connus de l'homme du métier et ne nécessitent donc pas une plus ample description dans le cadre de la présente invention.The working surfaces S 1 and S 2 are for example formed by smoothing plates respectively first and second 6. The smoothing plates 5 and 6 are each associated with electric heating means 7 in contact with the rear surface of the corresponding plate, located opposite the working surface S 1 , S 2 , as shown in FIG. figure 2 . The electric heating means can be made in any suitable manner such as for example in the form of a resistive heating element CTP or infrared emission. The electric heating means 7 are therefore located inside the first 1 and second 2 jaws. The heating means are connected by a cord 10 to a power supply such as an electricity distribution network. The cord 10 supplies control means 11 enabling a user to select a set temperature. Of course, the power supply of the hairdressing apparatus A could also be provided by batteries or batteries arranged inside one and / or the other jaws 1 and 2. Similarly, the means The heating means could also be designed to maintain a predetermined target temperature automatically. The embodiments of the heating means and the possible control unit are well known to those skilled in the art and therefore do not require further description in the scope of the present invention.

Conformément à une caractéristique essentielle de l'invention, l'appareil de coiffure A comprend en outre des moyens 20 de distribution d'un produit cosmétique fluide, sous forme liquide ou pâteuse, en vue de son application de manière automatique sur les cheveux pendant l'utilisation de l'appareil A. Les moyens de distribution 20 comprennent des moyens d'application 21 qui, comme le montre la figure 2 sont adjacents à la deuxième plaque de lissage 6 de manière à se trouver dans la zone Z de traitement des cheveux. Le réservoir V peut se situer sous la plaque de lissage 6 ce qui permet de réduire l'encombrement de la poignée et de chauffer légèrement le fluide cosmétique pour une meilleure efficacité à l'application.According to an essential characteristic of the invention, the hairstyling apparatus A further comprises means 20 for dispensing a fluid cosmetic product, in liquid or pasty form, for automatic application to the hair during the l use of the apparatus A. The dispensing means 20 comprise application means 21 which, as shown in FIG. figure 2 are adjacent to the second smoothing plate 6 so as to be in the zone Z of hair treatment. The tank V can be located under the smoothing plate 6 which reduces the size of the handle and slightly heat the cosmetic fluid for greater efficiency in the application.

Les moyens d'application 21 sont raccordés à un réservoir de produits 22 par un circuit d'alimentation 23 comme cela ressort plus particulièrement de la figure 3. Afin d'assurer l'alimentation des moyens d'application 21 les moyens de distribution 20 comprennent en amont des moyens d'application 21 une pompe 24 située sur le circuit d'alimentation 23 entre le réservoir 22 et les moyens d'application 21.The application means 21 are connected to a product reservoir 22 by a supply circuit 23, as is more particularly apparent from the figure 3 . In order to supply the application means 21, the distribution means 20 comprise, upstream of the application means 21, a pump 24 located on the supply circuit 23 between the reservoir 22 and the application means 21.

Conformément à une caractéristique essentielle de l'invention, la pompe 24 est manoeuvrée par le mouvement des moyens M de mise en forme, et dans le cas présent par le mouvement alterné des surfaces de travail S1, S2 et plus particulièrement des mâchoires 1 et 2, lors des cycles de fermeture / ouverture de l'appareil de coiffure A. Ainsi, l'alimentation en produit des moyens d'application 21 est automatique et asservie aux mouvements des mâchoires 1 et 2. Selon l'exemple illustré en figure 3, la pompe 24 comprend un corps rigide 26 qui définit avec un piston 27 une chambre de pompage 28 raccordée, d'une part, au réservoir 22 et, d'autre part, aux moyens d'application 21 par des segments correspondants du circuit d'alimentation 23. Le piston 27 est soumis à l'action de rappel d'au moins un et, selon l'exemple illustré, de deux ressorts 29. Le piston 27 porte une tige 30 qui s'étend en dehors de la deuxième mâchoire 2 de manière que son extrémité libre 31 offre une surface d'appui pour la première mâchoire 1. Ainsi, lorsque la première mâchoire 1 se referme vers la deuxième mâchoire 2, la première mâchoire vient appuyer sur la tige 30 de sorte que la translation vers le bas du piston 27 fait décroître le volume de la chambre de pompage 28. Lorsque la première mâchoire 1 est ouverte, la pression sur la tige 30 est relâchée et le piston 27 est repoussé par les ressorts 29 ce qui fait augmenter le volume de la chambre de pompage 28. Afin d'assurer un effet de pompage, les moyens de distribution comprennent sur le circuit de distribution en amont de la pompe 24, entre le réservoir 22 et cette dernière, un clapet anti-retour 35 adapté pour autoriser une circulation du produit du réservoir 22 vers la pompe 24 mais pas en sens inverse. De la même manière, les moyens de distribution 20 comprennent, entre le milieu extérieur et la pompe 24 au moins un et selon l'exemple illustré plusieurs clapets anti-retour 36 adaptés pour autoriser une circulation de produits de la pompe 24 vers les moyens d'application 21 et l'extérieur mais pas en sens inverse. Les clapets anti-retour 36 évitent ainsi une aspiration d'air. Selon l'exemple illustré, les clapets anti-retour 36 sont chacun formés par les deux lèvres élastiques d'une buse d'application du produit cosmétique de sorte qu'il y a autant de clapets anti-retour 36 que de buses.According to an essential characteristic of the invention, the pump 24 is manipulated by the movement of the shaping means M, and in this case by the alternating movement of the working surfaces S 1 , S 2 and more particularly the jaws 1 and 2, during the closing / opening cycles of the hairdressing apparatus A. Thus, the supply of product of the application means 21 is automatic and controlled by the movements of the jaws 1 and 2. According to the illustrated example in figure 3 the pump 24 comprises a rigid body 26 which defines with a piston 27 a pumping chamber 28 connected, on the one hand, to the reservoir 22 and, on the other hand, to the application means 21 by corresponding segments of the circuit 23. The piston 27 is subjected to the return action of at least one and, according to the illustrated example, two springs 29. The piston 27 carries a rod 30 which extends outside the second jaw 2 so that its free end 31 provides a bearing surface for the first jaw 1. Thus, when the first jaw 1 closes to the second jaw 2, the first jaw presses the rod 30 so that the translation to the bottom of the piston 27 decreases the volume of the pumping chamber 28. When the first jaw 1 is open, the pressure on the rod 30 is released and the piston 27 is pushed back by the springs 29 which increases the volume of the pumping chamber 28. In order to ensure pumping effect, the distribution means comprise on the distribution circuit upstream of the pump 24, between the reservoir 22 and the latter, a nonreturn valve 35 adapted to allow a flow of the product from the tank 22 to the pump 24 but not in the opposite direction. In the same way, the distribution means 20 comprise, between the external medium and the pump 24 at least one and according to the illustrated example, several non-return valves 36 adapted to allow a circulation of products from the pump 24 to the pump means. application 21 and the outside but not in the opposite direction. The non-return valves 36 thus avoid an air intake. According to the illustrated example, the non-return valves 36 are each formed by the two elastic lips of a nozzle for applying the cosmetic product so that there are as many check valves 36 as there are nozzles.

Ainsi le produit contenu dans le réservoir 22 est amené automatiquement aux moyens d'application 21 sans que l'utilisateur n'ait à se préoccuper de cette distribution ou de la quantité distribuée.Thus the product contained in the reservoir 22 is automatically brought to the application means 21 without the user having to worry about this distribution or the quantity dispensed.

Selon l'exemple illustré figure 3, le réservoir 22 est adapté de manière amovible dans un logement 45 de l'appareil de coiffure. Ainsi, l'utilisateur peut recharger facilement l'appareil en procédant simplement au remplacement du réservoir 22 qui vient s'engager sur une canule de vidange 46 s'étendant en saillie à l'intérieur du logement 45.According to the illustrated example figure 3 , the reservoir 22 is removably fitted in a housing 45 of the hairdressing apparatus. Thus, the user can easily recharge the device by simply replacing the reservoir 22 which engages on a discharge cannula 46 projecting inside the housing 45.

Selon l'exemple décrit précédemment en relation avec les figures 1 et 2, le corps 26 de la pompe 24 est rigide. Toutefois, un tel corps 26 rigide n'est pas nécessaire à la réalisation d'une pompe selon l'invention. Ainsi, la figure 4 illustre une variante de réalisation de l'appareil de coiffure selon laquelle le corps 26 de la pompe 24 est réalisé en un matériau souple élastiquement déformable. La pompe 24 utilisée peut être une pompe appelée à clapet plat, telle qu'illustrée en figure 10. Une telle pompe est compacte, endurante et peu chère. La première mâchoire 1 comprend alors un organe presseur 47 qui vient appuyer sur le corps 26 lors de la fermeture des mâchoires 1 et 2. La pression exercée par l'organe presseur 47 sur le corps souple 26 induit l'expulsion du produit qu'il contient vers les moyens d'application 21. L'organe presseur 47 peut être monté sur ressort 47' dont la force est choisie pour assurer une vitesse maîtrisée de distribution du fluide au travers des moyens d'application 21, qui sont par exemple un ou des tubes longitudinaux d'application 21. L'organe exerce une force sur le bombé de la pompe à clapet comme illustré en figure 10. Lorsque la pression de l'organe presseur 47 est relâchée, à l'ouverture des mâchoires 1 et 2, le corps souple élastique 26 reprend alors naturellement sa forme ce qui contribue à aspirer le produit depuis le réservoir 22 dans la chambre de pompage 28 par le clapet anti-retour 35. L'organe presseur 47 peut être relevé pour annihiler la fonction de distribution de cosmétique, au choix de l'utilisateur, cette possibilité étant illustrée en figure 4 mais étant envisagée dans tous les modes de réalisation du lisseur ou fer à friser.According to the example described above in relation to the Figures 1 and 2 the body 26 of the pump 24 is rigid. However, such a rigid body 26 is not necessary for the realization of a pump according to the invention. So, the figure 4 illustrates an alternative embodiment of the hairdressing apparatus according to which the body 26 of the pump 24 is made of an elastically deformable flexible material. The pump 24 used may be a pump called a flap valve, as illustrated in FIG. figure 10 . Such a pump is compact, enduring and inexpensive. The first jaw 1 then comprises a pressing member 47 which presses on the body 26 during closure of the jaws 1 and 2. The pressure exerted by the pressing member 47 on the flexible body 26 induces the expulsion of the product it contains the means of application 21. The pressing member 47 may be spring-mounted 47 'whose force is chosen to ensure a controlled rate of distribution of the fluid through the application means 21, which are for example one or longitudinal longitudinal application 21. The member exerts a force on the bulge of the valve pump as shown in FIG. figure 10 . When the pressure of the pressing member 47 is released, at the opening of the jaws 1 and 2, the resilient flexible body 26 then naturally resumes its shape which helps to suck the product from the reservoir 22 into the pumping chamber 28. the check valve 35. The pressing member 47 can be raised to annihilate the cosmetic dispensing function, at the option of the user, this possibility being illustrated in FIG. figure 4 but being contemplated in all embodiments of the straightener or curling iron.

Plusieurs pompes peuvent être alternativement envisagées. Un premier mode est une pompe à clapet plat illustrée en figures 10 et 4. Un deuxième mode est une pompe péristaltique à galets multiples, illustrée en figure 8. Toujours pour une pompe péristaltique, il peut s'agir d'une pompe péristaltique manuelle telle qu'illustrée en figure 11. La force F est exercée par l'organe presseur de sorte que dans un premier temps le galet 26' est appuyé contre la canalisation pour la rendre étanche, et, dans un deuxième temps, l'organe presseur intermédiaire courbé 26" est appuyé contre la canalisation pour avancer le volume de cosmétique dans le sens indiqué vers les moyens d'application 21. Une telle pompe est compacte et peu chère.Several pumps can be alternatively considered. A first mode is a flat flap pump illustrated in figures 10 and 4 . A second mode is a peristaltic pump with multiple rollers, illustrated in figure 8 . Still for a peristaltic pump, it may be a manual peristaltic pump as illustrated in FIG. figure 11 . The force F is exerted by the pressing member so that at first the roller 26 'is pressed against the pipe to make it tight, and, in a second step, the intermediate bent pressing member 26 "is pressed against the channeling to advance the volume of cosmetics in the direction indicated towards the application means 21. Such a pump is compact and inexpensive.

La variante de réalisation illustrée à la figure 4 diffère également, de la variante décrite en relation avec les figures 1 à 3, en ce que les moyens d'application 21 sont formés par une chambre 48 qui s'ouvre vers l'extérieur par une série de buses d'application 49. Au sens de l'invention, une buse de distribution peut être formée par tout orifice de toute forme adaptée pour permettre le passage du produit de traitement vers l'extérieur et plus particulièrement vers les cheveux de l'utilisateur de l'appareil de coiffure A. Ces buses peuvent être des fentes particulièrement étanches, issue d'une fabrication dite de « fentes refendues » après extrusion du tuyau. La chambre 48 peut être un tuyau ou plusieurs tuyaux parallèles les uns aux autres, en silicone ou matériau similaire et dont les buses 49 sont des fentes étanches réparties axialement uniformément pour une distribution du cosmétique aussi homogène que possible. Il doit être remarqué que les buses de distribution ou d'application 49 pourraient également être remplacées ou complétées par un matériau poreux tel qu'un matériau synthétique alvéolaire à alvéoles ouvertes ou encore un feutre textile. Ce matériau peut être une mousse à cellule ouverte, dont la direction des ouvertures est dirigée depuis les buses vers la surface extérieure qui est destinée à être en contact avec les cheveux. L'organe presseur 47 peut être relevé par l'utilisateur pour annihiler la fonction de distribution de cosmétique, au choix de l'utilisateur, cette possibilité étant illustré en figure 4 mais étant envisagée dans tous les modes de réalisation du lisseur ou fer à friser.The embodiment variant illustrated in figure 4 also differs from the variant described in relation to the Figures 1 to 3 , in that the application means 21 are formed by a chamber 48 which opens outwards through a series of application nozzles 49. Within the meaning of the invention, a dispensing nozzle may be formed by any orifice of any shape adapted to allow the passage of the treatment product to the outside and more particularly to the hair of the user of the hairdressing apparatus A. These nozzles may be particularly tight slots, resulting from a so-called manufacturing "slit slits" after extrusion of the pipe. The chamber 48 may be a pipe or several pipes parallel to each other, made of silicone or similar material and whose nozzles 49 are airtight slots distributed axially uniformly for a distribution of the cosmetic as homogeneous as possible. It should be noted that the dispensing or application nozzles 49 could also be replaced or supplemented by a porous material such as an open-cell cellular synthetic material or a textile felt. This material may be an open cell foam, the direction of the openings being directed from the nozzles to the outer surface which is intended to be in contact with the hair. The pressing member 47 can be raised by the user to annihilate the cosmetic dispensing function, at the user's choice, this possibility being illustrated in FIG. figure 4 but being contemplated in all embodiments of the straightener or curling iron.

Selon l'exemple décrit en relation avec la figure 3 le réservoir 22 est amovible. Toutefois, selon l'invention le réservoir 22 pourrait être solidaire de l'appareil de coiffure A, sans être amovible, comme cela est illustré à la figure 4. Selon cet exemple, le réservoir 22 comprend alors un orifice de remplissage 50 destiné à recevoir une canule 51 de remplissage d'un tube de conditionnement 52 de produit cosmétique. Selon cet exemple l'orifice de remplissage 50 est associé à un clapet anti-retour 53 évitant toute fuite de produit après remplissage du réservoir 22.According to the example described in relation to the figure 3 the reservoir 22 is removable. However, according to the invention, the reservoir 22 could be integral with the hairdressing apparatus A, without being removable, as illustrated in FIG. figure 4 . According to this example, the reservoir 22 then comprises a filling orifice 50 intended to receive a cannula 51 for filling a cosmetic product conditioning tube 52. According to this example, the filling orifice 50 is associated with a non-return valve 53 preventing any leakage of product after filling the reservoir 22.

Selon les formes de réalisation décrites précédemment, la pompe 24 est actionnée à chaque fermeture de l'appareil de coiffure A. Toutefois, une telle périodicité de l'action de la pompe 24 n'est pas nécessaire à la réalisation des moyens de distribution 20 selon l'invention. En effet, selon le type de moyens d'application 21 utilisés il peut être souhaitable de n'actionner la pompe qu'après un nombre prédéterminé d'ouverture/fermeture des mâchoires 1 et 2. Pour ce faire, l'invention propose dans une variante de réalisation, de mettre en oeuvre des moyens de manoeuvre 60 qui sont adaptés pour manoeuvrer chaque pompe de l'appareil de coiffure après un nombre prédéterminé de mouvements consécutifs d'ouverture/fermeture. Selon les moyens et l'exemple illustré à la figure 7, les moyens de manoeuvre 60 comprennent un doigt intercalaire 61 mobile en translation entre une position de repos R telle qu'illustrée à la figure 7 en traits pleins et une position de travail T représentée en traits mixtes. En position de travail T, le doigt intercalaire 61 est placé entre l'organe presseur 47 et le corps souple 26 de la pompe de sorte qu'une pression peut être exercée sur ledit corps 26 lorsque les mâchoires 1 et 2 sont fermées. En revanche en position de repos R, le doigt intercalaire 61 est dégagé par rapport à l'organe presseur 47 et au corps souple 26 de sorte qu'en position fermée des mâchoires aucune pression n'est exercée sur le corps souple 26 de la pompe. Le doigt intercalaire 61 est en outre manoeuvré par une came 62 entraînée en rotation par un système de roue à rochet 63 qui transforme les mouvements d'ouverture/fermeture des mâchoires en une rotation de la came 62 dans le sens de la flèche F1. La came 62 comprend alors des protubérances 64 adaptées pour venir repousser régulièrement le doigt intercalaire 61 en position de travail tandis qu'il est rappelé en position de repos par un ressort 65. Les protubérances 64 sont, selon l'exemple illustré, disposées à la périphérie de la came 62 de manière à déplacer le doigt intercalaire 61 en position de travail toutes les deux fermetures de l'appareil de coiffure A de sorte que la pompe 24 est actionnée une fois sur deux.According to the embodiments described above, the pump 24 is actuated at each closure of the hairdressing apparatus A. However, such a periodicity of the action of the pump 24 is not necessary for the realization of the dispensing means 20 according to the invention. Indeed, depending on the type of application means 21 used it may be desirable to operate the pump only after a predetermined number of opening / closing jaws 1 and 2. To do this, the invention proposes in a embodiment, to implement operating means 60 which are adapted to operate each pump of the hairdressing appliance after a predetermined number of consecutive opening / closing movements. According to the means and the example illustrated in figure 7 , the operating means 60 comprise an intermediate finger 61 movable in translation between a rest position R as illustrated in FIG. figure 7 in full lines and a working position T shown in phantom. In the working position T, the intermediate finger 61 is placed between the pressing member 47 and the flexible body 26 of the pump so that pressure can be exerted on said body 26 when the jaws 1 and 2 are closed. On the other hand, in the rest position R, the intermediate finger 61 is disengaged relative to the pressing member 47 and the flexible body 26 so that in the closed position of the jaws no pressure is exerted on the flexible body 26 of the pump . The intermediate finger 61 is furthermore actuated by a cam 62 driven in rotation by a ratchet wheel system 63 which transforms the opening / closing movements of the jaws into a rotation of the cam 62 in the direction of the arrow F1. The cam 62 then comprises protuberances 64 adapted to regularly push the intermediate finger 61 into the working position while it is returned to the rest position by a spring 65. The protuberances 64 are, according to the illustrated example, arranged at the periphery of the cam 62 so as to move the intermediate finger 61 in the working position every two closures of the hairdressing apparatus A so that the pump 24 is actuated every other time.

Selon l'invention, la pompe des moyens d'application 21 n'est pas nécessairement une pompe à fonctionnement alternatif comme cela a été décrit précédemment. En effet, la pompe des moyens d'application 21 peut être une pompe péristaltique 24 (pompe 2) comme illustrée aux figures 8 ou 11. Selon l'exemple de réalisation illustré en figure 8, le corps 26 est réalisé sous la forme d'un tube souple élastique disposé en arc de cercle et sur lequel agissent des organes presseurs 70 espacés régulièrement à la périphérie d'une roue 71. Les moyens de manoeuvre 60 comprennent alors un système de roue à rochet 72 comprenant une roue 73 associée à un cliquet anti-retour 74. La roue est entraînée en rotation par un doigt 75 solidaire de la première mâchoire 1. Le doigt 75 est adapté pour agir sur la roue 73 de manière à l'entraîner dans le sens de la flèche F3 lors de la fermeture de la première mâchoire et pour permettre une ouverture libre de la première mâchoire 1 alors que la rotation de la roue en sens inverse à celui de la flèche F3 est interdite par le cliquet anti-retour 74. Le système de roue à rochet 72 transforme donc les mouvements d'ouverture/fermeture des mâchoires en une rotation de la roue 73 qui est liée à la roue 71 de manière à assurer le fonctionnement de la pompe 24. Alternativement, cette pompe peut être une pompe péristaltique manuelle comme illustrée en figure 10 avec un organe d'actionnement qui se déplace en deux temps : pour faire l'étanchéité, puis pour déplacer le fluide.According to the invention, the pump of the application means 21 is not necessarily a reciprocating pump as has been previously described. Indeed, the pump of the application means 21 may be a peristaltic pump 24 (pump 2) as illustrated in FIGS. figures 8 or 11 . According to the exemplary embodiment illustrated in figure 8 the body 26 is in the form of a resilient flexible tube disposed in an arc and on which pressure members 70 are regularly spaced at the periphery of a wheel 71. The actuating means 60 then comprise a wheel system ratchet 72 comprising a wheel 73 associated with a non-return pawl 74. The wheel is rotated by a finger 75 integral with the first jaw 1. The finger 75 is adapted to act on the wheel 73 so as to drive it in the direction of the arrow F3 when closing the first jaw and to allow free opening of the first jaw 1 while the rotation of the wheel in the opposite direction to that of the arrow F3 is prohibited by the non-return ratchet 74. The ratchet wheel system 72 therefore transforms the opening / closing movements of the jaws into a rotation of the wheel 73 which is connected to the wheel 71 so as to ensure the operation of the pump 24. Alternati This pump can be a manual peristaltic pump as illustrated in figure 10 with an actuator that moves in two stages: to seal, then to move the fluid.

Dans tous les cas de pompe, la figure 5 illustre schématiquement le fonctionnement de déplacement du fluide. Le fluide est contenu dans le réservoir 22, interchangeable ou rechargeable. Ce réservoir est en communication de fluide avec la pompe 24. Un tuyau silicone souple intermédiaire 24' agencé en série avec la pompe 24 (illustré en aval mais possible en amont) renforce et démultiplie le fonctionnement et le volume déplacé par la pompe 24. Ce tuyau est si souple qu'il est capable de se gonfler pour contenir un volume de cosmétique intermédiaire. La souplesse de ce tuyau intermédiaire est obtenue par son épaisseur fine, autour de 1mm (2mm habituellement). Il a été constaté que ceci permet d'avoir un gonflement élastique pour générer plus de volume de cosmétique (effet ballon de baudruche) et pour assurer une distribution de cosmétique beaucoup plus longue dans le temps (jusque deux fois plus longue), donc constante même pour les plus grandes longueurs de mèches. Le tuyau intermédiaire est suivi d'un clapet anti-retour 36 avec le tuyau silicone représentant les moyens d'application 21.In all pump cases, the figure 5 schematically illustrates the fluid displacement operation. The fluid is contained in the tank 22, interchangeable or rechargeable. This reservoir is in fluid communication with the pump 24. An intermediate flexible silicone hose 24 'arranged in series with the pump 24 (illustrated downstream but possible upstream) reinforces and reduces the operation and the volume displaced by the pump 24. hose is so flexible that it is able to inflate to contain a volume of intermediate cosmetic. The flexibility of this intermediate pipe is obtained by its thin thickness, around 1mm (2mm usually). It has been found that this makes it possible to have an elastic swelling to generate more cosmetic volume (balloon effect) and to ensure a cosmetic distribution that is much longer in time (up to twice as much). long), so constant even for the longest lengths of locks. The intermediate pipe is followed by a non-return valve 36 with the silicone pipe representing the application means 21.

Selon l'exemple décrit précédemment les surfaces de travail S1 et S2 sont sensiblement planes. Toutefois, les surfaces de travail S1 et S2 pourraient présenter d'autres formes en étant complémentaires l'une de l'autre. Les surfaces de travail peuvent, par exemple, présenter chacune une forme incurvée. Ainsi, l'appareil de coiffure selon l'invention peut former un fer à boucler ou à friser tel qu'illustré à la figure 12.According to the example described above the working surfaces S 1 and S 2 are substantially planar. However, the working surfaces S 1 and S 2 could have other forms being complementary to each other. The work surfaces may, for example, each have a curved shape. Thus, the hairdressing appliance according to the invention can form a curling or curling iron as illustrated in FIG. figure 12 .

Selon cette forme de réalisation, la première mâchoire 1 définit, dans sa partie située du côté du cordon électrique 10, des moyens de préhension P. La surface de travail S1, située à l'opposé des moyens de préhension P, possède une forme sensiblement cylindrique de révolution et se trouve associée à des moyens de chauffage non représentés. La première surface de travail S1 est en outre pourvue de buses 49 de distribution ou d'application de produit cosmétique. La deuxième mâchoire 2 est articulée sur la première mâchoire 1, à distance des extrémités de celle-ci, entre les moyens de préhension P et la première surface de travail S1. La deuxième surface de travail S2 présente la forme d'une tuile adaptée pour épouser la forme de la première surface de travail S1. Selon cet exemple, la deuxième surface de travail S2 n'est pas associée à des moyens de chauffage. La deuxième mâchoire 2 comprend à l'opposé de la deuxième surface de travail S2 par rapport à l'articulation charnière ou liaison pivot 4, une branche ou organe de manoeuvre 70 qui permet d'ouvrir l'appareil de coiffure A. La branche de manoeuvre 70 appuie alors pendant l'ouverture de la deuxième mâchoire sur la tige 30 de la pompe 24, non visible à la figure 8, pour assurer la distribution de produits par les buses 49. La pompe peut être réalisée comme décrit en relation avec la figure 3 tandis que les moyens d'application peuvent être réalisés comme décrit en relation avec la figure 4.According to this embodiment, the first jaw 1 defines, in its part located on the side of the electrical cord 10, gripping means P. The working surface S 1 , located opposite the gripping means P, has a shape substantially cylindrical of revolution and is associated with heating means not shown. The first working surface S 1 is further provided with nozzles 49 for dispensing or applying a cosmetic product. The second jaw 2 is articulated on the first jaw 1, at a distance from the ends thereof, between the gripping means P and the first working surface S 1 . The second work surface S 2 has the shape of a tile adapted to match the shape of the first work surface S 1 . According to this example, the second working surface S 2 is not associated with heating means. The second jaw 2 comprises opposite the second working surface S 2 relative to the pivot hinge or pivot connection 4, a branch or actuating member 70 which opens the hairstyling apparatus A. The branch operating maneuver 70 then presses during the opening of the second jaw on the rod 30 of the pump 24, not visible at the figure 8 , to ensure the distribution of products through the nozzles 49. The pump can be carried out as described in connection with the figure 3 while the means of application can be realized as described in connection with the figure 4 .

Un appareil de coiffure à main selon l'invention n'est pas nécessairement un lisseur ou un fer à friser comme décrit précédemment mais peut également former une brosse rotative telle qu'illustrée à la figure 13. L'appareil de coiffure A comprend alors en tant que moyens de préhension P un manche 80 qui porte en tant que moyens M de mise en forme un rouleau 81 mobile en rotation, sur lui-même, par rapport au manche 80. Le rouleau 81 comprend des moyens 21 d'application de produit cosmétique qui sont alimentés par une pompe péristaltique 24 telle qu'illustrée à la figure 8 dont la roue 71 est entraînée par la rotation du rouleau 81. Le rouleau 81 comprend aussi des poils pour former une brosse rotative. Le rouleau est creux avec des orifices traversants pour l'air soufflé par un ensemble moteur- ventilateur 82. Un tel appareil de coiffure peut alors comprendre un moteur d'entraînement en rotation de ladite brosse 81 ainsi que des moyens électrique de soufflage d'air 82. Alternativement, une pompe à clapet plat illustrée en figure 10 est envisagée en regard d'un doigt destiné à appuyer sur la pompe à clapet plat à chaque rotation complète du corps de brosse 81. Encore alternativement, une pompe péristaltique manuelle illustrée en figure 11 est envisagée en regard d'un doigt destiné à appuyer la pompe à chaque rotation complète du corps de brosse 81.A hand-held hairdressing apparatus according to the invention is not necessarily a straightener or a curling iron as described above but may also form a rotary brush as illustrated in FIG. figure 13 . The hairstyling apparatus A then comprises, as gripping means P, a handle 80 which carries as a means M for shaping a roller 81 which is rotatable, on itself, with respect to the handle 80. The roller 81 comprises means 21 for applying a cosmetic product which are powered by a peristaltic pump 24 as illustrated in FIG. figure 8 whose wheel 71 is driven by the rotation of the roller 81. The roller 81 also comprises bristles to form a rotating brush. The roller is hollow with through orifices for the air blown by a motor-fan assembly 82. Such a hairdressing appliance may then comprise a motor for rotating said brush 81 as well as electric air blowing means. 82. Alternatively, a flat flap pump illustrated in figure 10 is envisaged opposite a finger for pressing the flat valve pump with each complete rotation of the brush body 81. Still alternatively, a manual peristaltic pump illustrated in FIG. figure 11 is envisaged opposite a finger intended to support the pump with each complete rotation of the brush body 81.

La figure 14, illustre encore une autre forme de réalisation d'un appareil de coiffure à main constituant, selon cet exemple, un boucleur dont les moyens de mise en forme M comprennent, d'une part, un rouleau 85 mobile en rotation sur lui-même et, d'autre part, une mâchoire 86 adaptée pour venir pincer les cheveux d'une mèche à traiter contre le rouleau 85. Le manche 80 de l'appareil comprend des moyens de soufflage d'air chaud non visibles à la figure. Le manche 80 de l'appareil comprend également une partie des moyens de distribution de produit cosmétique notamment le réservoir et la pompe non visibles à la figure pour alimenter les moyens d'application 21 aménagés dans la partie de la mâchoire 86 située en regard du rouleau 85. La rotation du rouleau 85 est alors mise à profit pour entraîner la pompe et assurer l'alimentation des moyens d'application 21. La pompe pourra alors être une pompe péristaltique telle que décrite à la figure 8. Selon l'exemple de la figure 14, la rotation manuelle du rouleau 85 est assurée au moyen d'un bouton molette 87 équipant l'extrémité libre du rouleau 85. Toutefois, la rotation du rouleau 85 pourrait également être assurée au moyen d'un moteur électrique disposé dans le manche 80.The figure 14 , illustrates yet another embodiment of a hand-held hairdressing device constituting, according to this example, a looper whose forming means M comprise, on the one hand, a roller 85 mobile in rotation on itself and on the other hand, a jaw 86 adapted to pinch the hair of a wick to be treated against the roller 85. The handle 80 of the apparatus comprises means for blowing hot air not visible in the figure. The handle 80 of the apparatus also comprises a portion of the cosmetic product dispensing means including the reservoir and the pump not visible in the figure for supplying the application means 21 arranged in the portion of the jaw 86 located opposite the roller 85. The rotation of the roller 85 is then used to drive the pump and supply the supply means 21. The pump can then be a peristaltic pump as described in the figure 8 . According to the example of the figure 14 the manual rotation of the roller 85 is ensured by means of a knob 87 fitted to the free end of the roller 85. However, the rotation of the roller 85 could also be ensured by means of an electric motor arranged in the handle 80.

Bien entendu, diverses autres modifications peuvent être apportées à un appareil de coiffure à main selon l'invention dans le cadre des revendications annexées.Of course, various other modifications may be made to a hand-held hairdressing apparatus according to the invention within the scope of the appended claims.
