Description

Domaine technique de l'inventionTechnical field of the invention

La présente invention concerne un appareil de coiffure ou de mise en forme des cheveux, plus particulièrement du type fer à boucler ou à friser ou brosse rotative soufflante comportant un boîtier relié à au moins un corps chauffant rotatif pour effectuer la mise en forme des cheveux par tout type de chaleur.The present invention relates to a hair styling device or hair shaping, more particularly to the type curling iron or curling or rotary blower brush having a housing connected to at least one rotary heating body to perform the shaping of the hair by any type of heat.

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

La plupart des appareils de mise en forme des cheveux, tels par exemple les fers à friser ou à boucler comportent une poignée supportant un mandrin chauffant et une pince de pression montée radialement sur le mandrin et destinée à amener les cheveux en contact avec le mandrin, notamment en passant d'une position d'ouverture permettant l'insertion des cheveux à une position de fermeture pour leur mise en contact avec le mandrin chauffant. Le passage de la position d'ouverture à celle de fermeture se fait manuellement en pressant un levier d'ouverture de la pince de pression. En utilisation, le mandrin est chauffé et le bout d'une mèche de cheveux est pris entre la pince de pression et le mandrin. La rotation manuelle ou automatique (motorisée par exemple) du fer à friser permet d'enrouler le reste de la mèche autour du mandrin. Le bouclage d'une mèche de cheveux se fait en enroulant au moins partiellement la mèche autour de la ou des surfaces de traitement et en appliquant de la chaleur pour fixer la boucle principalement en statique. La chaleur modifie la texture des cheveux et leur permet de prendre la forme du mandrin, en formant une boucle. La boucle est ensuite déroulée afin de la sortir du mandrin.Most hair shaping devices, such as curling or curling irons comprise a handle supporting a heating mandrel and a pressure clamp mounted radially on the mandrel and intended to bring the hair in contact with the mandrel, in particular by passing from an open position allowing the insertion of the hair to a closed position for their contact with the heating mandrel. The transition from the open position to the closing position is done manually by pressing an opening lever of the pressure clamp. In use, the mandrel is heated and the end of a lock of hair is caught between the pressure clamp and the mandrel. The manual or automatic rotation (motorized for example) of the curling iron allows to wrap the rest of the wick around the mandrel. The wrap of a lock of hair is made by at least partially winding the wick around the treatment surface (s) and applying heat to fix the loop mainly in static. The heat changes the texture of the hair and allows them to take the shape of the mandrel, forming a loop. The loop is then unwound to get out of the mandrel.

Le document US 4 829 156 décrit l'enroulement d'une mèche de cheveux autour d'un mandrin chauffant en proposant un entraînement en rotation par un moteur électrique du mandrin autour de son axe. En fonctionnement, l'extrémité d'une mèche de cheveux est pincée en ouvrant une languette montée pivotante autour d'une articulation du mandrin, puis, en actionnant un interrupteur le mandrin se met à tourner permettant ainsi l'enroulement automatique de la mèche sur le mandrin, et ce dans les deux sens de rotation. Ce fer à friser comporte une limitation d'effort par un dispositif mécanique de limitation (« clutch »). Si la tension exercée par la mèche de cheveux enroulée est trop forte alors la rotation est limitée.The document US 4,829,156 describes the winding of a lock of hair around a heating mandrel by providing a rotational drive by an electric motor of the mandrel about its axis. In operation, the end a lock of hair is pinched by opening a tongue pivotally mounted around a hinge of the mandrel, then, by actuating a switch, the mandrel starts to rotate, thus allowing the wick to be wound up automatically on the mandrel, and this in both directions of rotation. This curling iron has a limitation of effort by a mechanical device of limitation (" clutch "). If the tension exerted by the curled lock of hair is too strong then the rotation is limited.

Le document US 7481228 décrit un fer à boucler avec mandrin chauffant rotatif motorisé. En fonctionnement, l'extrémité d'une mèche de cheveux est placée en ouvrant une languette montée pivotante autour d'une articulation du mandrin, puis, en actionnant un interrupteur le mandrin se met à tourner permettant ainsi l'enroulement automatique de la mèche sur le mandrin, et ce dans les deux sens de rotation. Ce fer à friser comporte une languette qui peut insérer une tête de brosse avec des soies fixes ou rétractables et/ou une plaque de lissage.The document US 7481228 describes a curling iron with motorized rotating heating chuck. In operation, the end of a strand of hair is placed by opening a tongue pivotally mounted around a hinge of the mandrel, then, by actuating a switch, the mandrel starts to rotate, thus allowing the wick to be wound up automatically. the chuck, in both directions of rotation. This curling iron has a tongue that can insert a brush head with fixed or retractable bristles and / or a smoothing plate.

Le document US 2010 043818 décrit le dispositif du document US 7481228 avec un moteur ayant une protection de courant connue dans l'état de l'art. Si le courant dépasse un seuil par exemple seuil standard d'une prise de courant, ou si trop de courant est tiré, un circuit de commande peut de façon intermittente éteindre le moteur ou désactiver complètement l'appareil, tel un fusible.The document US 2010 043818 describes the device of the document US 7481228 with a motor having a current protection known in the state of the art. If the current exceeds a threshold eg standard threshold of a power outlet, or if too much current is pulled, a control circuit can intermittently turn off the motor or completely disable the device, such as a fuse.

Enfin, dans une catégorie similaire au fer à boucler mais couvrant également le domaine de l'invention, le document US3890984 décrit une brosse rotative soufflante combinant un sèche-cheveux et une brosse. De l'air chaud est soufflé au travers du mandrin de la brosse via une pluralité d'orifices ; le mandrin étant commandé dans les deux sens possibles de rotation grâce à un moteur agencé à l'intérieur de la poignée. Pour cet appareil, l'utilisateur va permettre au mandrin de tourner et d'entraîner sur moins d'un tour les cheveux afin de les « brusher », c'est-à-dire former une ondulation dans un seul sens de la mèche de cheveux traitée. Un interrupteur sur la poignée permet de changer le sens de rotation ou d'arrêter complètement la rotation. L'appareil inclut un interrupteur de surcharge (« switch overload) » apte à arrêter la rotation de la brosse quand les cheveux restent emmêlés dedans.Finally, in a category similar to curling iron but also covering the field of the invention, the document US3890984 describes a rotating fan brush combining a hair dryer and a brush. Hot air is blown through the brush mandrel via a plurality of orifices; the mandrel being controlled in the two possible directions of rotation by means of a motor arranged inside the handle. For this device, the user will allow the mandrel to rotate and drag on less than one turn the hair to " brusher ", that is to say, form a ripple in one direction of the wick of treated hair. A switch on the handle makes it possible to change the direction of rotation or stop the rotation completely. The device includes a overload switch (" switch overload ") able to stop the rotation of the brush when the hair remains entangled in it.

Le document US 4 664 132 décrit une brosse de coiffure motorisée rotative dans un sens et dans le sens inverse.The document US 4,664,132 describes a rotating motorized hairdressing brush in one direction and in the opposite direction.

Tous ces dispositifs de coiffure décrits présentent des mandrins rotatifs chauffants motorisés. Certains présentent un moteur d'entraînement du mandrin équipé d'une protection en courant connue de l'art sur le moteur. Le document US 4 944 319 décrit une brosse rotative dans un sens et dans le sens inverse. Cependant aucun de ces documents ne pose le problème du bon compromis entre l'efficacité de l'appareil et la sécurité pour ne pas brûler le cuir chevelu de l'utilisateur.All these hairstyling devices described have motorized heated rotary chucks. Some have a chuck drive motor equipped with current protection known in the art on the motor. The document US 4,944,319 describes a rotating brush in one direction and in the opposite direction. However none of these documents pose the problem of the good compromise between the efficiency of the device and the safety not to burn the scalp of the user.

En effet, l'utilisateur qui place une mèche de cheveux sur le mandrin chaud va ensuite appuyer sur le bouton pour faire tourner le mandrin et enrouler la mèche. Tant qu'il appuie sur le bouton, le mandrin est entraîné en rotation et enroule la mèche de cheveux.
Dans le cas des fers à boucler, lorsque l'utilisateur voit arriver près du cuir chevelu le mandrin chaud attaché à la mèche, il arrête la commande de rotation. Ainsi le mouvement est arrêté et le mandrin chaud ne touche pas le cuir chevelu et ne le brûle pas. Mais pour boucler toute la chevelure, lorsque l'utilisateur fait lui-même ses boucles, notamment derrière le crâne ou près de la nuque, il est plus difficile -voire impossible- de suivre visuellement le mandrin, de le voir s'approcher du cuir chevelu pour l'arrêter en position la plus efficace. On appelle position la plus efficace la position d'arrêt du mandrin suffisamment proche du cuir chevelu pour créer une boucle sur toute la longueur de la mèche et suffisamment éloignée pour ne pas toucher et/ou s'appuyer contre le cuir chevelu de sorte à le brûler.
Dans le cas des brosses soufflantes rotatives, si la mèche de cheveux s'enroule mal ou trop autour du mandrin de la brosse, elle risque d'emmêler les cheveux sur les soies et de coincer la mèche autour du mandrin.Indeed, the user who places a lock of hair on the hot mandrel will then press the button to rotate the mandrel and wind the wick. As long as it presses the button, the mandrel is rotated and wraps the lock of hair.
In the case of curling irons, when the user sees near the scalp the hot mandrel attached to the wick, it stops the rotation control. So the movement is stopped and the hot mandrel does not touch the scalp and does not burn it. But to complete the hair, when the user makes his own curls, especially behind the skull or near the neck, it is more difficult - if not impossible - to follow the chuck visually, to see him approaching the leather hairy to stop it in the most effective position. The most effective position is the stopping position of the mandrel sufficiently close to the scalp to create a loop over the entire length of the wick and far enough to not touch and / or lean against the scalp so as to burn.
In the case of rotating blower brushes, if the lock of hair wraps poorly or too tightly around the brush core, it may entangle the hair on the bristles and trap the wick around the mandrel.

Ainsi les appareils de l'état de la technique ne posent et ne résolvent pas le problème suivant : combiner efficacité et sécurité optimisées du fonctionnement en rotation du mandrin de l'appareil.
Et plus particulièrement pour les fers à boucler de l'état de l'art, ils ne posent et ne résolvent pas le problème suivant : permettre de créer une boucle sur substantiellement toute la longueur de la mèche de cheveux sans risquer de brûler le cuir chevelu.
Et plus particulièrement pour les brosses rotatives soufflantes, elles ne posent et ne résolvent pas le problème suivant : permettre de créer une ondulation sur substantiellement toute la longueur de la mèche de cheveux sans risquer d'emmêler le cuir chevelu.Thus the devices of the state of the art do not pose and do not solve the following problem: combine efficiency and optimized security of the rotating operation of the mandrel of the device.
And especially for state-of-the-art curling irons, they do not pose and do not solve the following problem: allow to create a loop on substantially the entire length of the lock of hair without risking burning the scalp.
And more particularly for the rotary blower brushes, they do not pose and do not solve the following problem: allow to create a ripple on substantially the entire length of the lock of hair without risk of entangling the scalp.

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

L'appareil de coiffure 1 selon les deux modes de l'invention et illustrés en figures , 2, 6 et 7 comporte un moyen de préhension ou poignée 2, un corps d'enroulement 3 d'une mèche de cheveux, des moyens d'entraînement 8 en rotation du corps d'enroulement 3 autour de son axe longitudinal L, des moyens d'entraînement 7 (représentés par 7' et 7" selon le mode de réalisation) des cheveux pour entraîner la mèche sur le corps d'enroulement 3, des moyens d'actionnement 10 du corps en rotation permettant à l'utilisateur de choisir un parmi les deux sens de rotation, une unité de contrôle 9 reliée aux moyens d'actionnement 10 et programmée pour commander les moyens d'entraînement 8 selon le sens choisi, l'unité de contrôle 9 est programmée pour commander les moyens d'entraînement 8 dans le sens inverse du sens de rotation choisi quand l'unité de contrôle 9 détecte un état de fonctionnement provoquant l'arrêt de la rotation.The hairdressing apparatus 1 according to the two modes of the invention and illustrated in figures, 2 , 6 and 7 comprises a gripping means or handle 2, a winding body 3 of a lock of hair, driving means 8 for rotating the winding body 3 about its longitudinal axis L, driving means 7 ( 7 'and 7 "according to the embodiment) of the hair for driving the wick on the winding body 3, means for actuating the body 10 in rotation allowing the user to choose one of the two directions of rotation, a control unit 9 connected to the actuating means 10 and programmed to control the drive means 8 in the selected direction, the control unit 9 is programmed to control the drive means 8 in the opposite direction of the direction of rotation chosen when the control unit 9 detects a state of operation causing the rotation to stop.

Dans le premier mode, qui concerne un fer à boucler ou fer à friser et est illustré en figures 1 et 2, les moyens d'entraînement 7" des cheveux sont des moyens de pincement pour placer une extrémité de mèche entre le corps 3 et la pince 7'. L'enroulement de mèche se fait sur quelques tours autour du corps.In the first mode, which concerns a curling iron or curling iron and is illustrated in Figures 1 and 2 the drive means 7 "of the hair are pinching means for placing a wick end between the body 3 and the gripper 7. The wick winding is made a few turns around the body.

Dans le deuxième mode, qui concerne une brosse soufflante rotative illustrée en figure 3, les moyens d'entraînement 7 sont les soies montées sur le corps 3, les soies permettant d'entraîner les cheveux sur le corps. L'enroulement de mèche se fait sur une partie du corps.In the second mode, which relates to a rotary blower brush illustrated in figure 3 , the driving means 7 are the bristles mounted on the body 3, the bristles for driving the hair on the body. The winding of wick is done on a part of the body.

Un tel appareil est d'une utilisation facile et intuitive, permet donc d'effectuer un traitement sans effort, avec plus de liberté et moins d'attention pour l'utilisateur, le système étant capable de produire automatiquement une rotation du mandrin en sens inversé au sens d'usage choisi, et ce, selon un angle fixé ou programmé. De cette façon, le mandrin chaud est éloigné automatiquement du cuir chevelu en fin de course, d'une petite longueur de cheveux Lc dont la taille est suffisamment grande pour que le mandrin ne brûle pas le cuir chevelu et suffisamment petite pour que la boucle soit formée sur toute la longueur de mèche sans que ce petit manque de bouclage au niveau de la racine ne se remarque. De cette façon également, les cheveux autour du mandrin ne sont pas emmêlés et le mandrin revient même automatiquement en arrière pour aider l'utilisateur à démêler.
Dans tous les modes, à la détection d'un état de fonctionnement provoquant l'arrêt de rotation, il peut être prévu grâce à un minuteur de commander un petit intervalle temporel (entre 0,1 et 1s) entre l'arrêt de rotation et le démarrage de la rotation dans le sens inverse, permettant ainsi d'éviter tout pic de courant, tout arrêt intempestif.Such a device is easy and intuitive to use, thus allows a treatment without effort, with more freedom and less attention for the user, the system being able to automatically produce a rotation of the mandrel in the opposite direction in the chosen usage sense, and this, according to a fixed or programmed angle. In this way, the hot mandrel is automatically moved away from the scalp at the end of the stroke, a short length of hair Lc whose size is large enough so that the mandrel does not burn the scalp and small enough so that the loop is formed on the entire length of wick without this small lack of looping at the root is noticeable. In this way also, the hair around the mandrel is not entangled and the mandrel even automatically returns back to help the user to unravel.
In all modes, upon detection of an operating state causing rotation stoppage, it can be provided by a timer to control a small time interval (between 0.1 and 1s) between the stop rotation and the start of the rotation in the opposite direction, thus avoiding any current spike, any untimely stop.

L'appareil de coiffure de l'invention comporte d'abord un corps d'enroulement chauffant et motorisé, apte donc à enrouler automatiquement une mèche de cheveux à partir d'une extrémité de celle-ci et jusqu'à la racine des cheveux. L'extrémité de la mèche est fixée au corps d'enroulement par une pince d'accrochage, l'actionnement en rotation du corps d'enroulement autour de son axe longitudinal permettant de réaliser l'enroulement automatique de la mèche sur la surface externe d'enroulement de celui-ci. Ainsi, un tel enroulement automatique permet déjà de réduire le temps d'enroulement et rendre l'opération facile pour l'utilisatrice, la mèche pouvant ainsi rapidement recouvrir la surface externe du corps d'enroulement. De surcroît, en utilisant un moyen d'accroche ou de fixation efficace et en adaptant la vitesse de rotation du moteur aux dimensions du corps d'enroulement, voire au type de cheveux à traiter, on obtient un enroulement efficace pour une mise en tension optimale et uniforme de la mèche enroulée. Les moyens de fixation peuvent être une pince 7' qui s'étend sur au moins une partie du corps d'enroulement ou tout autre moyen permettant de fixer la mèche au corps par son extrémité libre et permettant ainsi l'enroulement de la mèche sans qu'elle ne glisse. Les moyens de pincement sont aptes à passer d'une position d'ouverture sans contact avec la surface externe 5 du corps à une position de fermeture en contact avec la surface externe 5 du corps. Ils peuvent être actionnés par un bouton 17 comme illustré en figure 2. L'invention prévoit un retour en rotation automatique du mandrin de faible ampleur à l'arrêt de la rotation, permet un déroulement automatique d'une faible longueur de la mèche enroulée.The hairdressing apparatus of the invention comprises firstly a heating and motorized winding body, able to automatically wind a lock of hair from one end thereof to the hairline. The end of the wick is attached to the winding body by a clamp hooking, the actuation in rotation of the winding body about its longitudinal axis to achieve the automatic winding of the wick on the outer winding surface thereof. Thus, such automatic winding already reduces the winding time and make the operation easy for the user, the wick can thus quickly cover the outer surface of the winding body. Moreover, by using an effective means of attachment or attachment and by adapting the rotational speed of the motor to the dimensions of the winding body, or even to the type of hair to be treated, an effective winding is obtained for optimum tensioning. and uniform of the wick rolled up. The fixing means may be a clamp 7 'which extends over at least a part of the winding body or any other means for fixing the wick to the body by its free end and thus allowing the winding of the wick it does not slip. The clamping means is adapted to move from an open position without contact with the outer surface 5 of the body to a closed position in contact with the outer surface 5 of the body. They can be actuated by a button 17 as illustrated in figure 2 . The invention provides for an automatic return to rotation of the mandrel of small amplitude at the end of the rotation, allows an automatic unwinding of a short length of the wound wick.

Selon l'invention, l'unité de contrôle 9 peut être programmée pour détecter un état de fonctionnement provoquant l'arrêt de la rotation dans au moins un des cas suivants : une action de l'utilisateur sur les moyens d'actionnement 10, un couple des moyens d'entraînement 8 supérieur à un couple seuil (souvent prédéterminé), un court-circuit, une panne d'alimentation.According to the invention, the control unit 9 can be programmed to detect an operating state causing the stopping of the rotation in at least one of the following cases: an action of the user on the actuating means 10, a torque drive means 8 greater than a threshold torque (often predetermined), a short circuit, a power failure.

Dans tous les cas listés, ce retour en rotation « arrière » ou « inversée » du mandrin s'effectue automatiquement lorsqu'un arrêt est souhaité par l'utilisateur et/ou est programmé par l'appareil qui détecte un problème (seuil courant, seuil résistance court-circuit...). L'action de l'utilisateur peut être un actionnement ou un relâchement de bouton.In all the cases listed, this "backward" or "reverse" rotation of the mandrel occurs automatically when a stop is desired by the user and / or is programmed by the device which detects a problem (current threshold, threshold resistance short circuit ...). The action of the user can be an actuation or a button release.

Selon l'invention, l'unité de contrôle 9 peut être programmée pour entraîner le corps d'enroulement en rotation dans le sens inverse selon un angle de retour α compris entre 20° et 180° voire un angle compris entre 25° et 90°, préférentiellement égal à environ 45°. De cette façon, le mandrin chaud est éloigné automatiquement du cuir chevelu en fin de course, d'un certain angle assurant une certaine longueur de cheveux Lc dont la taille est suffisamment grande pour que le mandrin ne brûle pas le cuir chevelu et suffisamment petite pour que la boucle soit formée sur toute la longueur de mèche sans qu'un manque de bouclage au niveau de la racine ne puisse se remarquer.According to the invention, the control unit 9 can be programmed to drive the winding body rotating in the opposite direction at a return angle α of between 20 ° and 180 ° or an angle of between 25 ° and 90 °, preferably equal to about 45 °. In this way, the hot mandrel is automatically moved away from the scalp at the end of the stroke, at a certain angle ensuring a certain length of hair Lc whose size is large enough so that the mandrel does not burn the scalp and small enough to that the loop is formed over the entire length of wick without a lack of looping at the root can not be noticed.

Selon l'invention, l'appareil peut comprendre un bouton de réglage 14 de la valeur de l'angle de retour α. La valeur de l'angle α peut ainsi être entrée et fixée par le fabricant, ou peut être alternativement choisie et modifiée par l'utilisateur qui choisira à l'usage la valeur la plus pratique, la valeur étant mémorisée dans l'unité de contrôle.According to the invention, the apparatus may comprise an adjusting knob 14 for the value of the return angle α. The value of the angle α can thus be entered and fixed by the manufacturer, or alternatively can be selected and modified by the user who will choose in use the most practical value, the value being stored in the control unit. .

Selon l'invention, l'unité de contrôle 9 peut être programmée pour commander une vitesse en sens inverse supérieure ou égale à la vitesse du sens d'enroulement choisi. Le mode de vitesse substantiellement égale est préféré car la vitesse de retour identique ne change pas la perception de vitesse de l'utilisateur. Le mode de vitesse supérieure renforce le caractère sécuritaire de l'appareil et s'éloigne plus vite du cuir chevelu qu'en mode d'enroulement de mèche. Un mode de vitesse inférieure pourrait néanmoins être envisagé pour donner l'impression d'arrêt en rotation à l'utilisateur.According to the invention, the control unit 9 can be programmed to control a reverse speed greater than or equal to the speed of the selected winding direction. The substantially equal speed mode is preferred because the identical return speed does not change the user's speed perception. The higher speed mode enhances the safety of the device and moves away from the scalp faster than the wicking mode. A lower speed mode could nevertheless be considered to give the user the impression of stopping rotation.

Selon l'invention, les moyens d'entraînement 8 peuvent être aptes à produire une vitesse de rotation comprise entre 5 et 50 tr/min, voire entre 10 et 40 tr/min. Une valeur avantageuse de rotation est autour de 30 tr/min. Il a été constaté, lors de tests effectués en laboratoire, que cette plage de vitesses permet de réaliser la plupart des types de boucles de différents diamètres, tout en assurant une bonne mise sous tension des cheveux pendant l'enroulement.According to the invention, the drive means 8 may be able to produce a rotation speed of between 5 and 50 rpm, or even between 10 and 40 rpm. An advantageous value of rotation is around 30 rpm. It has been found, in laboratory tests, that this range of speeds makes it possible to produce most types of loops of different diameters, while ensuring good tensioning of the hair during winding.

Selon l'invention, les moyens d'entraînement 8 peuvent comporter un moteur électrique, préférentiellement un motoréducteur. L'appareil peut comprendre des moyens pour limiter le couple du moteur, ces moyens pour limiter le couple comprennent un microprocesseur apte à suivre le courant absorbé par le motoréducteur et à couper l'alimentation électrique de celui-ci si un seuil limite est dépassé, et, préférentiellement immédiatement après, à commander celui-ci pour une rotation en sens inverse. Les moyens pour limiter le couple du moteur permettent d'éviter qu'une trop forte tension soit appliquée aux cheveux, soit à la fin de l'enroulement, soit lorsqu'un problème est arrivé pendant l'enroulement. Ceci représente une solution simple et fiable en fonctionnement, s'intègre bien dans un appareil compact et léger, tout en permettant d'éviter l'utilisation d'un embrayage plus encombrant.According to the invention, the drive means 8 may comprise an electric motor, preferably a geared motor. The apparatus may include means for limiting the torque of the motor, these means for limiting the torque comprise a microprocessor adapted to monitor the current absorbed by the geared motor and cut off the power supply thereof if a threshold is exceeded, and preferably immediately after, to control it for a rotation in the opposite direction. The means for limiting the torque of the motor make it possible to prevent excessive tension being applied to the hair, either at the end of the winding or when a problem has occurred during winding. This represents a simple and reliable solution in operation, fits well in a compact and lightweight device, while avoiding the use of a clutch more bulky.

Selon l'invention, et comme illustré en figure 1, les moyens d'actionnement 10 peuvent comprendre au moins un premier bouton de commande 10' de rotation du moteur dans le sens horaire et un deuxième bouton de commande 10" de rotation du moteur dans le sens antihoraire (ou inversement), l'état de fonctionnement provoquant l'arrêt de la rotation correspondant notamment à l'arrêt de l'actionnement par l'utilisateur d'un des deux boutons. Ces deux boutons peuvent être intégrés en un seul bouton qui sera actionné par basculement de deux côtés différents.
Ces moyens de commande du sens de rotation du corps d'enroulement, permettent à l'utilisateur, en actionnant en début de fonctionnement ces moyens de commande, de choisir le sens de rotation et donc le sens d'enroulement des cheveux afin d'obtenir soit une boucle externe, soit une boucle interne. Après chauffe de la mèche bouclée, en changeant le sens de rotation du moteur à la fin du traitement, on commande le déroulement de la boucle précédemment formée.According to the invention, and as illustrated in figure 1 , the actuating means 10 may comprise at least a first control knob 10 'of rotation of the motor in the clockwise direction and a second control knob 10 "of rotation of the motor counterclockwise (or vice versa), the state operating mode causing the stopping of rotation corresponding in particular to the stop of the actuation by the user of one of the two buttons.These two buttons can be integrated into a single button that will be operated by tilting two different sides.
These control means of the direction of rotation of the winding body, allow the user, by operating at the beginning of operation these control means, to choose the direction of rotation and thus the winding direction of the hair to obtain either an outer loop or an inner loop. After heating the looped loop, by changing the direction of rotation of the motor at the end of the treatment, it controls the unwinding of the previously formed loop.

Selon l'invention, les moyens d'entraînement 7 des cheveux sont des moyens de fixation 7 (par exemple des moyens de pincement) et le corps d'enroulement 3 peut présenter une forme de révolution où le rayon de courbure des moyens de fixation 7 est supérieur ou égal à celui du corps d'enroulement 3 dans une même section transversale de l'appareil. Un rayon de la plaque chauffante égal à celui du corps d'enroulement permet à la plaque chauffante de bien épouser la périphérie du corps d'enroulement, un rayon supérieur lui permettant de s'adapter à des mèches d'épaisseur importante. Les moyens de fixation, la pince par exemple, peuvent, en position fermée être en contact avec le corps, comme illustré en figures 1 et 2, et alternativement peuvent laisser un petit intervalle avec le corps de l'ordre de un ou quelques millimètres car l'épaisseur de la mèche lui permettra quand même d'être pincée entre les deux pièces 3 et 7.According to the invention, the drive means 7 of the hair are fastening means 7 (for example gripping means) and the winding body 3 may have a shape of revolution where the radius of curvature of the fixing means 7 is greater than or equal to that of the winding body 3 in the same cross section of the apparatus. A radius of the heating plate equal to that of the winding body allows the heating plate to marry well the periphery of the winding body, an upper radius allowing it to adapt to wicks of significant thickness. The fastening means, the clamp for example, may, in the closed position, be in contact with the body, as illustrated in FIG. Figures 1 and 2 , and alternatively may leave a small gap with the body of the order of one or a few millimeters because the thickness of the wick will still allow it to be pinched between the two pieces 3 and 7.

Selon l'invention, le rayon r du corps d'enroulement peut être compris entre 5mm et 25mm, préférentiellement entre 10mm et 20mm. Une valeur avantageuse du rayon r est substantiellement égale à 12mm ou substantiellement égale à 16mm.According to the invention, the radius r of the winding body can be between 5mm and 25mm, preferably between 10mm and 20mm. An advantageous value of the radius r is substantially equal to 12mm or substantially equal to 16mm.

Selon l'invention, des moyens de chauffe 4 peuvent être associés au corps d'enroulement 3. Ils peuvent être éventuellement associés à des moyens de régulation 9, 11 de sa température. Les moyens de chauffage peuvent être au moins un des moyens suivants, seul ou en combinaison : un élément chauffé par conduction, un élément chauffant par rayonnement, par exemple un élément résistif (céramique...), un élément chauffant par air chaud soufflé (comme illustré en figure 6) un élément chauffant par vaporisation de vapeur d'eau via des orifices du corps d'enroulement ...
De préférence, la surface interne de la pince a une longueur comparable à celle de la surface externe du corps d'enroulement (voire, au moins égale à la moitié de celle-ci) afin de pouvoir traiter uniformément des mèches longues de cheveux. En effet il a été constaté, lors des tests effectués en laboratoire, que les facteurs déterminants pour obtenir un enroulement bien formé et durable sont : la bonne tension d'enroulement, la qualité du transfert d'énergie, qui dépend essentiellement de la qualité du contact de la mèche avec l'élément chauffant, et également l'énergie transmise aux cheveux.According to the invention, heating means 4 may be associated with the winding body 3. They may optionally be associated with regulation means 9, 11 of its temperature. The heating means may be at least one of the following means, alone or in combination: a conductive heated element, a radiant heating element, for example a resistive element (ceramic, etc.), a heated hot air heating element ( as illustrated in figure 6 ) a heating element by vaporization of water vapor via orifices of the winding body ...
Preferably, the inner surface of the clamp has a length comparable to that of the outer surface of the winding body (or even at least half of it) in order to be able to treat long strands of hair uniformly.
