The document US4267431 discloses a hairstyling device making it possible to automatically produce curls or waves on the hair fiber. Such a hairdressing appliance comprises in particular:
  • a gripping part,
  • a mandrel having a longitudinal axis and mounted to be able to rotate about its longitudinal axis, and
  • a winding element extending longitudinally with respect to the mandrel and configured to wind a lock of hair around the mandrel, the winding element being integral in rotation with the mandrel and comprising a proximal end pivotably mounted relative to the mandrel, 'winding member being movable between a spaced apart position in which a distal end of the winding member is spaced from the mandrel to promote insertion of a lock of hair between the winding member and the mandrel and a close position in which the winding member is brought closer to the mandrel to press the lock of hair against the mandrel.

L'appareil de coiffure décrit dans le document US4267431 est avantageusement pourvu d'un élément de chauffage configuré pour chauffer le mandrin de manière à améliorer le bouclage des mèches de cheveux enroulées autour du mandrin par l'élément d'enroulement.The hairdressing device described in the document US4267431 is advantageously provided with a heating element configured to heat the mandrel so as to improve the curling of the locks of hair wound around the mandrel by the winding element.

Cependant, l'effet de bouclage obtenu avec un tel appareil de coiffure n'est pas satisfaisant.However, the curling effect obtained with such a styling device is not satisfactory.

La présente invention vise à remédier à cet inconvénient.The present invention aims to remedy this drawback.

Le problème technique à la base de l'invention consiste donc à fournir un appareil de coiffure qui soit simple d'utilisation, tout en permettant de réaliser automatiquement des boucles ou ondulations régulières.The technical problem underlying the invention therefore consists in providing a hairstyling device which is easy to use, while allowing regular curls or waves to be produced automatically.

A cet effet, la présente invention concerne un appareil de coiffure selon la revendication 1, comprenant :

  • un mandrin présentant un axe longitudinal et monté mobile en rotation autour de son axe longitudinal, et
  • un élément d'enroulement s'étendant longitudinalement par rapport au mandrin et configuré pour enrouler une mèche de cheveux autour du mandrin, l'élément d'enroulement étant solidaire en rotation du mandrin et comprenant une extrémité proximale montée pivotante par rapport au mandrin, l'élément d'enroulement étant mobile entre une position écartée dans laquelle une extrémité distale de l'élément d'enroulement est écartée du mandrin pour favoriser l'insertion d'une mèche de cheveux entre l'élément d'enroulement et le mandrin et une position rapprochée dans laquelle l'élément d'enroulement est rapproché du mandrin pour plaquer la mèche de cheveux contre le mandrin,
l'appareil de coiffure étant caractérisé en ce qu'il comprend en outre un élément de guidage mobile mobile entre une position d'attente occupée lorsque l'élément d'enroulement est dans la position écartée et dans laquelle une mèche de cheveux peut être introduite en travers du mandrin et entre l'élément d'enroulement et le mandrin et une position de fonctionnement occupée lorsque l'élément d'enroulement est dans la position rapprochée, l'élément de guidage mobile étant déplacé de la position d'attente à la position de fonctionnement lorsque l'élément d'enroulement est déplacé de la position écartée à la position rapprochée et déplaçant en outre la mèche de cheveux introduite en travers du mandrin de manière à la positionner selon une orientation prédéterminée par rapport au mandrin lorsque l'élément de guidage mobile est déplacé de la position d'attente à la position de fonctionnement.To this end, the present invention relates to a hairdressing appliance according to claim 1, comprising:

Une telle configuration de l'appareil de coiffure 2, et plus particulièrement de l'élément d'enroulement 11 facilite le démoulage de la mèche de cheveux bouclée à l'issue d'un cycle de bouclage. Selon le mode de réalisation représenté sur la figure 12, la position angulaire finale est décalée angulairement de la position angulaire initiale d'un angle d'environ 90°.As shown on the figure 12 , the winding element 11 is mounted so as to be able to rotate between an initial angular position, corresponding to the start of a looping cycle, in which the winding element 11 is located substantially opposite a central portion of the cover movable protective cover 14, and a final angular position, corresponding to the end of a looping cycle, in which the winding element 11 is located opposite the fixed protective cover 16 and is held in the close position by the fixed protective cover 16. Such a configuration of the styling device 2, and more particularly of the winding element 11 facilitates the release of the curly lock of hair at the end of a curling cycle. According to the embodiment shown in figure 12 , the final angular position is angularly offset from the initial angular position by an angle of approximately 90 °.

Selon un tel mode de mise en œuvre de l'étape d'enroulement, le procédé de bouclage comprend de préférence une étape additionnelle réalisée après l'étape de retrait de la mèche de cheveux et consistant à repositionner automatiquement l'élément d'enroulement 11 dans la position angulaire initiale. L'élément d'enroulement est alors sollicité vers la position écartée par l'organe de sollicitation.According to such an embodiment of the winding step, the looping method preferably comprises an additional step carried out after the step of removing the lock of hair and consisting in automatically repositioning the winding element 11. in the initial angular position. The winding element is then biased towards the separated position by the biasing member.

Selon un tel mode de réalisation de l'invention, l'unité de commande est configurée pour commander automatiquement la rotation de la roue dentée 35 selon le premier sens de rotation ou le deuxième sens de rotation en fonction des déplacements de l'élément d'enroulement 11 entre ses positions rapprochée et écartée.According to such an embodiment of the invention, the control unit is configured to automatically control the rotation of the toothed wheel 35 according to the first direction of rotation or the second direction of rotation as a function of the movements of the element. winding 11 between its close and spread positions.

Comme il va de soi, l'invention ne se limite pas aux seules formes d'exécution de cet appareil de coiffure, décrites ci-dessus à titre d'exemples, elle en embrasse au contraire toutes les variantes de réalisation, dans la mesure où elles sont couvertes par les revendications annexées.As goes without saying, the invention is not limited to the only embodiments of this hairdressing appliance, described above by way of examples, it embraces on the contrary all the variant embodiments thereof, insofar as they are covered by the appended claims.
