Description

La présente invention concerne le domaine technique des appareils de coiffure tels que les fers à boucler ou encore les lisseurs.The present invention relates to the technical field of hairdressing appliances such as curling irons or straighteners.

De tels appareils comprennent généralement deux mâchoires dont l'une au moins est chauffante et qui sont articulées entre elles de manière à pouvoir pincer une mèche de cheveux devant être mise en forme. L'une des mâchoires ou les deux mâchoires sont alors chauffées directement ou indirectement par un organe de chauffage électrique dont la température est régulée par un système thermostatique pour atteindre une température déterminée en fonction d'une valeur de température éventuellement sélectionnée par un utilisateur de l'appareil.Such devices generally comprise two jaws at least one of which is heated and which are hinged together so as to be able to pinch a lock of hair to be shaped. One of the jaws or both jaws are then heated directly or indirectly by an electric heating member whose temperature is regulated by a thermostatic system to reach a temperature determined according to a temperature value possibly selected by a user of the 'apparatus.

Un tel type d'appareil de coiffure permet avec une certaine pratique d'obtenir un bon résultat de lissage. Ce bon résultat de lissage est obtenu en appliquant un effort de pression important pour maintenir les mâchoires fermées et appliquer une pression suffisante sur la mèche de cheveux à traiter. Eventuellement, l'utilisatrice peut avoir recours à ses deux mains pour augmenter cet effort en vue d'un meilleur résultat. Dans tous les cas, le maintien de cet effort de pression important pendant tout le cycle de traitement de la chevelure est pénible et contraignant pour l'utilisatrice. Des tests en laboratoire ont mis en évidence que la combinaison de la tension des cheveux et de la chaleur appliquée par le fer avec une pression de serrage raisonnable permet d'obtenir un résultat équivalent voire meilleur que celui obtenu avec le fer seul en appliquant une pression plus importante. EP1698249A décrit un appareil de lissage avec deux barres de friction.Such a type of hairdressing apparatus makes it possible with some practice to obtain a good smoothing result. This good smoothing result is obtained by applying a significant pressure force to keep the jaws closed and apply sufficient pressure on the lock of hair to be treated. Possibly, the user can use both hands to increase this effort for a better result. In all cases, the maintenance of this significant pressure effort during the entire treatment cycle of the hair is painful and restrictive for the user. Laboratory tests have shown that the combination of the tension of the hair and the heat applied by the iron with a reasonable clamping pressure makes it possible to obtain a result equivalent or even better than that obtained with iron alone by applying a pressure more important. EP1698249A describes a smoothing apparatus with two friction bars.

Afin de remédier à l'inconvénient précité de pénibilité et d'éventuelle monopolisation des deux mains, il est apparu le besoin d'un nouveau type de lisseur qui permette de recréer ces conditions de mises en tension et de chauffage des cheveux, sans que les deux mains soient mobilisées, de manière à faciliter la tâche de l'utilisateur.In order to remedy the aforementioned drawback of hardness and possible monopolization of both hands, it appeared the need for a new type of straightener that allows to recreate these conditions of tensioning and heating the hair, without the two hands are mobilized, so as to facilitate the task of the user.

Afin d'atteindre cet objectif, l'invention concerne un appareil de coiffure selon les revendications 1, 9 et 10 comprenant au moins :

  • deux mâchoires, première et deuxième, allongées et articulées entre elles pour être mobiles entre une position ouverte et une position fermée dans laquelle elles définissent par des surfaces de travail en regard une zone de traitement de cheveux,
  • des moyens électriques de chauffage associés à l'une au moins des surfaces de travail,
Selon l'invention, la première mâchoire comprend au moins une barre de friction qui est mobile par rapport à la surface de travail adjacente et par rapport à la première mâchoire et qui est adaptée pour coopérer avec un élément en regard de manière à définir, en position fermée des mâchoires sur une mèche de cheveux, une zone de traction générant, lors du déplacement de l'appareil, sur la mèche de cheveux une force de traction supérieure à la force de traction générée par la zone de traitement. On entend par « barre de friction mobile par rapport à la surface de travail adjacente » la mobilité relative des deux pièces. Ainsi la barre de friction est mobile par rapport à la mâchoire et la surface de travail fixe par rapport à la mâchoire, ou bien la barre de friction est mobile par rapport à la mâchoire et la surface de travail mobile par rapport à la mâchoire mais de façon différente, La barre de friction est aussi appelée barre de traction.In order to achieve this object, the invention relates to a hairdressing apparatus according to claims 1, 9 and 10 comprising at least:
  • two jaws, first and second, elongated and articulated together to be movable between an open position and a closed position in which they define by working surfaces facing a hair treatment area,
  • electric heating means associated with at least one of the working surfaces,
According to the invention, the first jaw comprises at least one friction bar which is movable with respect to the adjacent working surface and with respect to the first jaw and which is adapted to cooperate with a facing element so as to define, in closed position of the jaws on a lock of hair, a traction zone generating, during the movement of the device, on the lock of hair a tensile force greater than the traction force generated by the treatment zone. The term "movable friction bar relative to the adjacent work surface" the relative mobility of the two parts. Thus the friction bar is movable relative to the jaw and the fixed working surface relative to the jaw, or the friction bar is movable relative to the jaw and the working surface movable relative to the jaw but of different way, The friction bar is also called drawbar.

Afin d'obtenir ce différentiel de force de traction, la barre de friction peut par exemple être conçue pour qu'en position fermée des mâchoires, la zone de traction présente un coefficient de friction supérieur au coefficient de friction de la zone de traitement.In order to obtain this differential of traction force, the friction bar may for example be designed so that in the closed position of the jaws, the traction zone has a coefficient of friction greater than the coefficient of friction of the treatment zone.

Cette différence de traction ou de friction permet donc à un utilisateur, qui aura veillé à disposer l'appareil de coiffure de manière que la zone de traitement soit située entre la zone de traction et le cuir chevelu, de tendre la partie des cheveux situés entre le cuir chevelu et la zone de traction et donc notamment celle située dans la zone de traitement, de sorte que le chauffage des cheveux en traction dans la zone de traitement permet d'obtenir un lissage optimal et très nettement supérieur à celui qui résulterait d'un simple chauffage des cheveux.This difference in traction or friction therefore allows a user, who has made sure to arrange the hairstyling device so that the treatment area is located between the traction zone and the scalp, to stretch the part of the hair located between the scalp and the traction zone and therefore in particular that located in the treatment zone, so that the heating of the hair in traction in the treatment zone provides an optimal smoothing and much higher than that which would result from a simple heating of the hair.

Selon l'invention l'élément coopérant avec la barre de friction peut être soit porté par la deuxième mâchoire soit porté par la première mâchoire.According to the invention the element cooperating with the friction bar may be carried either by the second jaw or carried by the first jaw.

Par ailleurs, selon l'invention la barre de friction peut être située soit au niveau d'un bord extérieur de la zone de traitement, soit au contraire, au centre de cette dernière de manière que l'utilisateur n'ait pas à se préoccuper du sens dans lequel il utilise l'appareil de coiffure conforme à l'invention.Furthermore, according to the invention the friction bar can be located either at an outer edge of the treatment zone, or on the contrary, in the center of the latter so that the user does not have to worry about the direction in which he uses the hairdressing apparatus according to the invention.

La barre de friction peut être à côté du bord extérieur de la surface de traitement et en contact avec la surface de traitement de la même mâchoire, ladite surface de traitement présentant une surface plane destinée à entrer en contact avec la mèche de cheveux. La barre de friction peut venir en appui contre le côté de la surface de traitement et/ou sous la surface de traitement et/ou sous les bords latéraux de la surface de traitement.The friction bar may be beside the outer edge of the treatment surface and in contact with the treatment surface of the same jaw, said treatment surface having a flat surface for contacting the lock of hair. The friction bar may abut against the side of the treatment surface and / or under the treatment surface and / or under the lateral edges of the treatment surface.

Selon l'invention, la mobilité de la barre de friction par rapport à la surface de travail adjacente peut être réalisée de différentes manières.According to the invention, the mobility of the friction bar relative to the adjacent working surface can be achieved in different ways.

Selon une première variante de réalisation la barre de friction est mobile par rapport à la première mâchoire et l'appareil comprend des moyens de contrainte qui sont interposés entre la barre de friction et la première mâchoire, et qui tendent à éloigner la barre de friction de la première mâchoire, c'est-à-dire qui repoussent la barre de friction vers la deuxième mâchoire.According to a first variant embodiment, the friction bar is movable with respect to the first jaw and the apparatus comprises means of constraint which are interposed between the friction bar and the first jaw, and which tend to move the friction bar away from the first jaw. the first jaw, that is to say, pushing the friction bar to the second jaw.

Les moyens de contrainte peuvent alors être réalisés de toute façon appropriée comme, par exemple mais non exclusivement, sous la forme d'un ou plusieurs ressorts travaillant en compression interposés entre la barre de friction et la première mâchoire. Les moyens de contrainte pourraient également être réalisés sous la forme de systèmes magnétiques, électromécaniques, pneumatiques ou hydrauliques. Les moyens de contrainte peuvent aussi être associés à des moyens de réglage de l'intensité de la contrainte qu'ils exercent.The constraining means can then be made in any suitable manner such as, for example but not exclusively, in the form of one or more springs working in compression interposed between the friction bar and the first jaw. The constraining means could also be made in the form of magnetic, electromechanical, pneumatic or hydraulic systems. The constraint means can also be associated with means for adjusting the intensity of the stress they exert.

Selon l'invention, la surface de travail peut être fixe par rapport à la mâchoire qui la porte tandis que la barre de friction est mobile par rapport à la première mâchoire et donc à la surface de travail. Toutefois selon l'invention, la surface de travail peut également être mobile par rapport à la première mâchoire qui la porte. Dans ce cas, la barre de friction peut être mobile par rapport à la mâchoire selon une contrainte différente, inférieure par exemple, à la contrainte exercée sur la surface de travail. Le résultat reste que la zone de traction générant lors du déplacement de l'appareil sur la mèche de cheveux une force de traction est supérieure à la force de traction générée par la zone de traitement adjacente.According to the invention, the working surface can be fixed relative to the jaw which carries it while the friction bar is movable relative to the first jaw and thus to the working surface. However according to the invention, the working surface can also be movable relative to the first jaw which carries it. In this case, the friction bar may be movable relative to the jaw according to a different constraint, for example less than the stress exerted on the working surface. The result is that the traction zone generating during the movement of the device on the lock of hair a pulling force is greater than the pulling force generated by the adjacent treatment area.

Selon une variante de réalisation de l'invention, la surface de travail, adjacente à la première barre de friction, est formée par une plaque de lissage mobile par rapport à la première mâchoire.According to an alternative embodiment of the invention, the working surface, adjacent to the first friction bar, is formed by a smoothing plate movable relative to the first jaw.

Dans le cadre de cette variante de réalisation, la barre de friction et la plaque de lissage peuvent être mobiles indépendamment l'une de l'autre par rapport à la première mâchoire qui les porte.In the context of this variant embodiment, the friction bar and the smoothing plate may be movable independently of one another relative to the first jaw which carries them.

Dans le cas où la surface de travail de la première mâchoire est formée par une plaque de lissage mobile, l'appareil de lissage selon l'invention peut comprendre des moyens de contrainte qui sont interposés entre la plaque de lissage et la première mâchoire, et qui tendent à éloigner la barre de friction de la première mâchoire.
Dans le cas où la barre de friction et la plaque de lissage sont toutes deux mobiles par rapport à la première mâchoire en étant indépendantes l'une de l'autre et chacune associée à des moyens de contrainte, les moyens de contrainte associés à la plaque de lissage peuvent être adaptés pour exercer sur ladite plaque une contrainte inférieure à la contrainte exercée sur la barre de friction par les moyens de contrainte associés à ladite barre. Un tel différentiel de pression permet d'assurer que la friction sera plus élevée au niveau de la barre de friction qu'au niveau de la plaque de lissage. Ainsi lors du déplacement de l'appareil, la zone de traction appliquera à la mèche de cheveux une force de traction supérieure à la force de traction générée par la zone de traitement, ce qui garantira une mise en tension optimale des cheveux. Ce différentiel de friction peut également être optimisé en mettant en oeuvre les matériaux présentant des coefficients de frottement différents pour d'une part la surface de contact de la barre de friction avec les cheveux et, d'autre part, la surface de contact de la plaque de lissage avec les cheveux.Ainsi, la barre de friction mobile relativement à la surface de travail adjacente couvre au moins deux combinaisons : la barre de friction mobile par rapport à la mâchoire avec la surface de travail adjacente mobile par rapport à la mâchoire ; la barre de friction mobile par rapport à la mâchoire avec la surface de travail adjacente immobile par rapport à la mâchoire.In the case where the working surface of the first jaw is formed by a mobile smoothing plate, the smoothing apparatus according to the invention may comprise stressing means which are interposed between the smoothing plate and the first jaw, and which tend to move the friction bar away from the first jaw.
In the case where the friction bar and the smoothing plate are both movable relative to the first jaw being independent of each other and each associated with means of stress, the stress means associated with the plate smoothing may be adapted to exert on said plate a stress less than the stress exerted on the friction bar by the stress means associated with said bar. Such a pressure differential makes it possible to ensure that the friction will be higher at the level of the friction bar than at the level of the smoothing plate. Thus during movement of the device, the traction zone will apply to the lock of hair a tensile force greater than the traction force generated by the treatment zone, which will ensure optimal tensioning of the hair. This friction differential can also be optimized by using materials having different coefficients of friction for firstly the contact surface of the friction bar with the hair and, secondly, the contact surface of the Thus, the movable friction bar relative to the adjacent work surface covers at least two combinations: the movable friction bar relative to the jaw with the adjacent working surface movable relative to the jaw; the movable friction bar with respect to the jaw with the adjacent working surface immobile compared to the jaw.

Selon une autre forme de réalisation de l'appareil de coiffure conforme à l'invention :

  • la barre de friction est portée par une extrémité libre d'un bras qui est articulé par une extrémité opposée sur la première mâchoire,
  • la surface de travail, adjacente à la barre de friction, est formée par une plaque de lissage mobile, par rapport à la première mâchoire, en translation selon une direction perpendiculaire à un axe longitudinal de la première mâchoire,
  • la première plaque de lissage est solidaire d'un doigt de traction adapté pour exercer une traction sur le bras articulé lorsque la plaque de lissage se déplace en translation à l'opposé de la barre de friction.
According to another embodiment of the hairdressing appliance according to the invention:
  • the friction bar is carried by a free end of an arm which is articulated by an opposite end on the first jaw,
  • the working surface, adjacent to the friction bar, is formed by a smoothing plate movable, with respect to the first jaw, in translation in a direction perpendicular to a longitudinal axis of the first jaw,
  • the first smoothing plate is integral with a traction finger adapted to exert traction on the articulated arm when the smoothing plate moves in translation opposite the friction bar.

En position de repos, le bras articulé est alors de préférence incliné par rapport à la surface de travail de la plaque de lissage, de sorte que la traction exercée par cette dernière sur le bras contribue à éloigner la barre de friction de la première mâchoire et donc à pincer la mèche de cheveu entre ladite barre de friction et l'élément en regard de la deuxième mâchoire. Une telle forme de réalisation permet donc un pincement et une traction de la mèche de cheveu dans un sens prédéterminé de déplacement de l'appareil de coiffure.In the rest position, the articulated arm is then preferably inclined relative to the working surface of the smoothing plate, so that the traction exerted by the latter on the arm helps to move the friction bar away from the first jaw and therefore to pinch the hair strand between said friction bar and the element facing the second jaw. Such an embodiment thus allows pinching and pulling of the hair strand in a predetermined direction of movement of the hair styling apparatus.

Afin de permettre un tel pincement et une telle mise en tension automatique de la mèche de cheveu dans les deux sens de déplacement de l'appareil de coiffure, ce dernier peut également être réalisé de manière que :

  • la première mâchoire comprend une deuxième barre de friction qui est située à l'opposée de la première barre de friction par rapport à la plaque de lissage et qui est portée par une extrémité libre d'un deuxième bras qui est articulé par une extrémité opposée, sur la première mâchoire, la deuxième barre de friction étant adaptée pour coopérer avec un élément en regard de la deuxième mâchoire de manière à définir une deuxième zone de traction présentant un coefficient de friction supérieur au coefficient de friction de la zone de traitement,
  • la plaque de lissage est solidaire d'un deuxième doigt de traction adapté pour exercer une traction sur le bras articulé lorsque la plaque de lissage se déplace en translation à l'opposé de la deuxième barre de friction.
In order to allow such a pinch and such an automatic tensioning of the hair strand in the two directions of movement of the hair-styling apparatus, the latter can also be made in such a way that:
  • the first jaw comprises a second friction bar which is situated opposite the first friction bar with respect to the smoothing plate and which is carried by a free end of a second arm which is articulated by an opposite end, on the first jaw, the second friction bar being adapted to cooperate with an element facing the second jaw so as to define a second traction zone having a coefficient of friction greater than the coefficient of friction of the treatment zone,
  • the smoothing plate is secured to a second traction finger adapted to exert traction on the articulated arm when the smoothing plate moves in translation opposite the second friction bar.

Selon l'invention, l'élément situé en regard de chaque barre de friction peut être de toute nature et par exemple constitué par une partie d'une plaque de lissage portée par la deuxième mâchoire. La contrepartie de chaque barre de friction peut également être formée par une barre de friction portée par la deuxième mâchoire, cette deuxième barre de friction ou contre-barre de friction peut alors avoir un montage analogue à celui de la barre de friction de la première mâchoire, mobile par rapport à la surface de travail adjacente. Ainsi, l'appareil de coiffure peut être réalisé de manière que :

  • la deuxième mâchoire comprend également une contre-barre de friction qui est portée par une extrémité libre d'un bras qui est articulé, par une extrémité opposée, sur la deuxième mâchoire, la contre-barre barre de friction de la deuxième mâchoire étant située en regard d'une barre de friction de la première mâchoire pour former la zone de traction,
  • la surface de travail de la deuxième mâchoire, adjacente à la barre de friction, est formée par une deuxième plaque de lissage mobile, par rapport à la deuxième mâchoire, en translation selon une direction perpendiculaire à un axe longitudinal de la deuxième mâchoire,
  • la deuxième plaque de lissage est solidaire d'un doigt de traction adapté pour exercer une traction sur le bras articulé lorsque la plaque de lissage se déplace en translation à l'opposé de la contre-barre de friction.
According to the invention, the element located opposite each friction bar may be of any kind and for example constituted by a portion of a smoothing plate carried by the second jaw. The counterpart of each friction bar can also be formed by a friction bar carried by the second jaw, this second friction bar or against-friction bar can then have a mounting similar to that of the friction bar of the first jaw movable relative to the adjacent work surface. Thus, the hairdressing appliance can be made in such a way that:
  • the second jaw also comprises a counter-friction bar which is carried by a free end of an arm which is articulated, by an opposite end, on the second jaw, the counter-bar friction bar of the second jaw being located in look at a friction bar of the first jaw to form the traction zone,
  • the working surface of the second jaw, adjacent to the friction bar, is formed by a second mobile smoothing plate, relative to the second jaw, in translation in a direction perpendicular to a longitudinal axis of the second jaw,
  • the second smoothing plate is secured to a traction finger adapted to exert a traction on the articulated arm when the smoothing plate moves in translation opposite the counter-friction bar.

De la même façon, l'appareil de coiffure selon l'invention peut être réalisé de manière que :

  • la deuxième mâchoire comprend une deuxième contre-barre de friction qui est située à l'opposée de la première contre-barre de friction par rapport à la deuxième plaque de lissage et qui est portée par une extrémité libre d'un deuxième bras qui est articulé, par une extrémité opposée, sur la deuxième mâchoire, la deuxième contre-barre de friction étant adaptée pour coopérer avec la deuxième barre de friction de la première mâchoire de manière à définir la deuxième zone de traction,
  • la deuxième plaque de lissage est solidaire d'un deuxième doigt de traction adapté pour exercer une traction sur le deuxième bras articulé lorsque la deuxième plaque de lissage se déplace en translation à l'opposé de la deuxième contre-barre de friction.
In the same way, the hairdressing appliance according to the invention can be made in such a way that:
  • the second jaw comprises a second counter-friction bar which is located opposite the first counter-friction bar with respect to the second smoothing plate and which is carried by a free end of a second arm which is articulated at an opposite end, on the second jaw, the second counter-friction bar being adapted to cooperate with the second friction bar of the first jaw so as to define the second traction zone,
  • the second smoothing plate is secured to a second traction finger adapted to exert traction on the second articulated arm when the second smoothing plate moves in translation opposite the second counter-friction bar.

Afin de garantir un différentiel de friction optimal entre la zone de travail et la zone de traction, l'appareil de coiffure selon l'invention peut être réalisé de manière qu'en position ouverte des mâchoires, chaque surface de travail d'une mâchoire est en retrait par rapport à chaque barre de friction ou chaque contre-barre de friction portée par ladite mâchoire. La valeur de ce retrait mesuré perpendiculairement à la surface de travail peut par exemple être comprise entre 0,1 mm et 5 mm.In order to guarantee an optimum friction differential between the working zone and the traction zone, the hairdressing apparatus according to the invention can be made in such a way that in the open position of the jaws, each working surface of a jaw is recessed relative to each friction bar or each against-friction bar carried by said jaw. The value of this shrinkage measured perpendicularly to the working surface may for example be between 0.1 mm and 5 mm.

Selon encore une autre forme de réalisation de l'appareil de coiffure, la première mâchoire comprend une pluralité de barres de friction qui sont chacune mobiles par rapport à la surface de travail adjacente selon une direction parallèle à un axe longitudinal de la première mâchoire et qui forment chacune une dent destinée à coopérer avec une contredent pour définir une zone de traction. Chaque contredent peut alors être portée par la première mâchoire ou au contraire être portée par la deuxième mâchoire.According to yet another embodiment of the hairdressing apparatus, the first jaw comprises a plurality of friction bars which are each movable relative to the adjacent working surface in a direction parallel to a longitudinal axis of the first jaw and which each form a tooth intended to cooperate with a contradiction to define a traction zone. Each contredent can then be carried by the first jaw or on the contrary be carried by the second jaw.

Par ailleurs, dans l'ensemble des modes de réalisation de l'invention précédemment décrits, la barre de friction peut être froide ou chaude.Furthermore, in all the embodiments of the invention described above, the friction bar may be cold or hot.

Elle peut être chaude par un moyen « passif » de chauffage, l'énergie venant de la plaque par conduction thermique et/ou chauffée par des moyens de chauffage « actifs » notamment électriques du type CTP ou céramique.It can be hot by a "passive" means of heating, the energy coming from the plate by thermal conduction and / or heated by "active" heating means including electrical type CTP or ceramic.

Dans le cas de chauffage par conduction thermique, la ou les barres de friction adjacentes sont en contact au moins partiellement avec une des surfaces de travail chauffées elle-même par des moyens électriques. Le contact peut s'effectuer sur le côté et/ou sur le dessous de la plaque de travail. La barre de traction peut être à côté du bord extérieur de la surface de traitement et en contact thermique avec la surface de traitement de la même mâchoire, ladite surface de traitement présentant une surface plane destinée à entrer en contact thermique avec la mèche de cheveux. La barre de traction peut venir en appui contre le côté de la surface de traitement et/ou sous la surface de traitement et/ou sous les bords latéraux de la surface de traitement.In the case of heat conduction heating, the at least one adjacent friction bar is in at least partial contact with one of the working surfaces itself heated by electrical means. The contact can be made on the side and / or on the underside of the work plate. The drawbar may be adjacent to the outer edge of the treatment surface and in thermal contact with the treatment surface of the same jaw, said treatment surface having a planar surface for thermal contact with the lock of hair. The drawbar may abut against the side of the treatment surface and / or under the treatment surface and / or under the side edges of the treatment surface.

Dans le cas de chauffage électriques, ces moyens de chauffage électriques peuvent alors être les moyens de chauffage associés à la surface de travail adjacente ou des moyens de chauffage électriques distincts, complémentaires de ceux de la surface de travail adjacente. Bien entendu, les différentes caractéristiques, formes et variantes de réalisations 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.In the case of electric heating, these electric heating means may then be the heating means associated with the adjacent working surface or separate electric heating means, complementary to those of the adjacent working surface. Of course, the various features, shapes and variants of embodiments of the invention can be associated with each other in various combinations to the extent that they are not incompatible or exclusive of each other.

Aussi, dans l'ensemble des modes de réalisation de l'invention décrits, la barre de friction ou la surface de la barre de friction destinée à être en contact avec la mèche de cheveux peut être composée ou revêtue au moins partiellement d'un matériau particulier, notamment en silicone. La couche de silicone peut avoir une épaisseur comprise entre 1 et 10mm, elle peut avoir une dureté entre 5 et 90 shores, préférentiellement dans une gamme entre 40 et 50 shores, préférentiellement égale à 46 shore A. Le silicone est résistant à température élevée au moins au dessus de 100°C, voire 150°C et jusqu'à environ 270°C, voire même 300°C.Also, in all the embodiments of the invention described, the friction bar or the surface of the friction bar intended to be in contact with the lock of hair may be composed or at least partially coated with a material particular, in particular silicone. The silicone layer may have a thickness of between 1 and 10 mm, it may have a hardness between 5 and 90 shores, preferably in a range between 40 and 50 shores, preferably equal to 46 shore A. The silicone is resistant to high temperature at less above 100 ° C, or even 150 ° C and up to about 270 ° C, or even 300 ° C.

Ce silicone peut être surmoulé, serti ou sur système de glissière sur la barrette de lame de friction. Ce silicone a pour but de tendre, freiner, plaquer homogéneiquement la mèche de cheveux sur le contre-appui au regard de la barre de friction. Bien entendu tout matériau alternatif au silicone et permettant d'atteindre au moins un des trois résultats mentionnés peut être utilisé par l'homme du métier.This silicone can be overmolded, crimped or on slide system on the friction blade bar. This silicone aims to tender, brake, homogeneously flatten the lock of hair against the support against the friction bar. Of course any material alternative to silicone and to achieve at least one of the three results mentioned can be used by those skilled in the art.

Sur ces figures, les références communes désignent des éléments communs aux différentes formes de réalisation.In these figures, the common references designate elements common to the different embodiments.

Un appareil de coiffure conforme à l'invention, tel qu'illustré à la figure 1 et désigné dans son ensemble par la référence A comprend deux mâchoires allongées 1 et 2 de forme générale parallélépipédique et s'étendant chacune 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 Δ. Ainsi, les mâchoires 1 et 2 sont articulées entre elles et mobiles entre une position ouverte O telle qu'illustrée à la figure 1 et 2, et une position fermée représentée à la figure 3. Chaque mâchoire 1 et 2 comprend à proximité d'une extrémité opposée à la liaison 4, une surface de travail respectivement S1, S2. Ces 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 de traitement des cheveux. 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 à faible coefficient de friction ou d'un émail à faible coefficient de friction ou encore d'une couche de verre.A hairdressing apparatus according to the invention, as illustrated in FIG. figure 1 and generally designated by the reference A comprises two elongate jaws 1 and 2 of generally parallelepipedal shape and each extending along a longitudinal axis L. The jaws 1 and 2 are connected near one of their ends by a hinge or pivot link 4 with axis Δ. Thus, the jaws 1 and 2 are hinged together and movable between an open position O as illustrated in FIG. figure 1 and 2 , and a closed position represented at figure 3 . Each jaw 1 and 2 comprises near an end opposite the link 4, a working surface respectively S 1 , S 2 . These working surfaces S 1 , S 2 are located facing each other and extend over only a portion of the length of the jaws 1 and 2, so as to define in the closed position a hair treatment area . Each work surface S 1 and S 2 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 with a low coefficient of friction or a low enamel coefficient of friction or a layer of glass.

Selon une première forme de réalisation et comme le montrent plus particulièrement les figures 2 et 3, la surface de travail S2 de la deuxième mâchoire 2 est formée par une plaque de lissage 5 qui s'étend sur toute la largeur de la deuxième mâchoire 2 en étant fixée de manière rigide sur cette dernière. La plaque de lissage 5 est alors associée à des moyens électriques de chauffage 6 en contact avec la face arrière de la plaque 5, située à l'opposé de la surface de travail S2. Les moyens électriques de chauffage 6 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 6 sont donc situés à l'intérieur de la deuxième mâchoire 2. Les moyens de chauffage 6 sont par exemple conçus pour maintenir une température cible prédéterminée de manière automatique. Les moyens de chauffage 6 pourraient également être reliés à des moyens de commande non représentés permettant une sélection, par un utilisateur, d'une température de consigne. Les moyens de chauffage et/ou leur unité de commande sont alimentés en énergie électrique par un cordon de branchement qui s'étend à partir d'une extrémité de la deuxième mâchoire 2 opposée à la surface de travail S2. 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. 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.According to a first embodiment and as shown more particularly by figures 2 and 3 , the working surface S 2 of the second jaw 2 is formed by a smoothing plate 5 which extends over the entire width of the second jaw 2 being fixed rigidly thereon. The smoothing plate 5 is then associated with electric heating means 6 in contact with the rear face of the plate 5, located opposite the working surface S 2 . The electric heating means 6 can be made in any appropriate manner such as for example in the form of a resistive heating element CTP or infrared emission. The electric heating means 6 are therefore located inside the second jaw 2. The heating means 6 are for example designed to maintain a predetermined target temperature automatically. The heating means 6 could also be connected to unrepresented control means allowing selection by a user of a set temperature. The heating means and / or their control unit are supplied with electrical energy by a connecting cord which extends from one end of the second jaw 2 opposite to the working surface S 2 . 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 of the jaws 1 and 2. The embodiments of FIG. 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 context of the present invention.

Selon l'exemple illustré, la surface S1 de la première mâchoire 1 est formée par une plaque de lissage 7 qui peut être adaptée sur la première mâchoire 1 de manière à être mobile en translation selon une direction N perpendiculaire à la surface de travail S1. L'appareil A comprend alors des moyens de contrainte 8 interposés entre la plaque de lissage 7 et la première mâchoire 1. Les moyens de contrainte sont par exemple formés par un ou plusieurs ressorts hélicoïdaux qui tendent à éloigner la plaque de lissage 7 de la première mâchoire 1. Les ressorts 8 repoussent donc la plaque de lissage 7 en direction de la deuxième mâchoire 2 et plus particulièrement de la surface de travail S2 de la plaque de lissage 5.According to the illustrated example, the surface S 1 of the first jaw 1 is formed by a smoothing plate 7 which can be fitted on the first jaw 1 so as to be able to move in translation along a direction N perpendicular to the working surface S 1 . The apparatus A then comprises constraint means 8 interposed between the smoothing plate 7 and the first jaw 1. The constraining means are for example formed by one or more helical springs which tend to move the smoothing plate 7 away from the first one. jaw 1. The springs 8 therefore push the smoothing plate 7 towards the second jaw 2 and more particularly the working surface S 2 of the smoothing plate 5.

Selon l'exemple illustré, la première mâchoire 1 comprend également le long d'un côté de la plaque de lissage 7, une barre de friction 10 qui est mobile par rapport à la surface de travail S1 et, selon l'exemple illustré, également par rapport à la première mâchoire 1. En effet, selon l'exemple illustré, la barre de friction 10 s'étend le long du bord gauche de la plaque de lissage 7 et se trouve mobile en translation par rapport à la première mâchoire selon une direction N' parallèle à la direction N et donc perpendiculaire à un plan défini par la surface de travail S1. L'appareil de coiffure A comprend alors des moyens de contrainte 11 interposés entre la première mâchoire 1 et la barre de friction 10. Ces moyens de contraintes 11 qui peuvent être de même nature que les moyens de contraintes 8 tendent donc à éloigner la barre de friction 10 de la première mâchoire et à la repousser vers la deuxième mâchoire 2.According to the illustrated example, the first jaw 1 also comprises, along one side of the smoothing plate 7, a friction bar 10 which is movable with respect to the working surface S 1 and, according to the illustrated example, also in relation to the first jaw 1. In fact, according to the illustrated example, the friction bar 10 extends along the left edge of the smoothing plate 7 and is movable in translation relative to the first jaw according to the first jaw. a direction N 'parallel to the direction N and therefore perpendicular to a plane defined by the working surface S 1 . The hairstyling apparatus A then comprises stressing means 11 interposed between the first jaw 1 and the friction bar 10. These stressing means 11, which may be of the same nature as the stressing means 8, therefore tend to move the bar friction 10 of the first jaw and push it towards the second jaw 2.

Un autre mode de réalisation est présenté en figure 2'. Il reprend toutes les caractéristiques décrites ici pour le mode de la figure 2 et diffère en ce que la barre de friction 10 est en contact thermique avec la surface de travail S1.Another embodiment is presented in figure 2 ' . It has all the features described here for the mode of the figure 2 and differs in that the friction bar 10 is in thermal contact with the working surface S 1 .

La barre de friction définit une protubérance longitudinale 12 en retrait par rapport à la surface de la zone de friction qui est destinée à venir en contact avec les cheveux. Cette protubérance vient en appui contre la surface S4 intérieure de la plaque de lissage et/ou le côté de la barre de friction vient en contact thermique avec la surface S3 latérale de la plaque de lissage. La conduction thermique est permise par ces contacts contre le côté de la plaque et et sous les bords latéraux de la plaque.
Et particulièrement, si la barre de friction est mobile, en position ouverte du lisseur. Par des tests de température, on s'est aperçu par cette disposition que la barre de friction peut chauffée à une température avoisinant les 100-110°C lorsque la température de la plaque de lissage avoisine les 150°C. Cette configuration peut bien entendu être appliquée aux modes de réalisation présentés en figure 4 et 5.The friction bar defines a longitudinal protuberance 12 set back from the surface of the friction zone which is intended to come into contact with the hair. This protrusion abuts against the inner surface S 4 of the smoothing plate and / or the side of the friction bar comes into thermal contact with the lateral surface S 3 of the smoothing plate. Thermal conduction is allowed by these contacts against the side of the plate and and under the side edges of the plate.
And especially, if the friction bar is movable, in the open position of the straightener. By temperature tests, it was found by this provision that the friction bar can be heated to a temperature of about 100-110 ° C when the temperature of the smoothing plate is around 150 ° C. This configuration can of course be applied to the embodiments presented in figure 4 and 5 .

Un autre mode de réalisation proche de celui de la figure 2 est également présenté en figure 2". Selon ce mode, la barre de friction présente une base intérieure 13 plus grande que dans le mode précédent permettant de recevoir un moyen de fixation ou un moyen de pression plus encombrant ou plus large (un ressort plus large par exemple) sans nécessiter la protubérance 12 du mode de la figure 2'. Cette configuration peut bien entendu être appliquée aux modes de réalisation présentés en figure 4 et 5. La barre de friction est à côté du bord extérieur de la plaque et en contact thermique avec une plaque de lissage de la même mâchoire, ladite plaque présentant une surface plane destinée à entrer en contact thermique avec la mèche de cheveux. La barre de traction vient en appui et sous les bords latéraux de la plaque.Another embodiment close to that of the figure 2 is also presented in figure 2 In this mode, the friction bar has an inner base 13 larger than in the previous mode for receiving a fastening means or a more bulky or wider pressure means (a wider spring for example) without requiring the protuberance 12 of the mode of the figure 2 ' . This configuration can of course be applied to the embodiments presented in figure 4 and 5 . The friction bar is next to the outer edge of the plate and in thermal contact with a smoothing plate of the same jaw, said plate having a flat surface intended to come into thermal contact with the lock of hair. The drawbar bears against and under the lateral edges of the plate.

La lame de tension peut être montée sur au moins deux ressorts 11 substantiellement agencés aux deux extrémités longitudinales de la barre de friction.The tensioning blade can be mounted on at least two springs 11 substantially arranged at both longitudinal ends of the friction bar.

L'appareil de coiffure A ainsi constitué est mis en oeuvre de la manière suivante. Lorsqu'un utilisateur souhaite procéder au lissage d'une mèche M de cheveux, il vient refermer l'appareil A sur ladite mèche, comme le montre la figure 2. L'utilisateur aura alors veillé à placer la barre de friction 10 à l'opposé du cuir chevelu C par rapport à la plaque de lissage 7. La barre de friction 10 définit alors avec la partie en regard de la plaque de lissage 5, une zone de traction 12 de la mèche de cheveux M. En effet, les moyens de contraintes 11 et 8 sont adaptés pour que la pression exercée sur la mèche de cheveu M par la barre de friction 10 soit supérieure à celle exercée par la plaque de lissage 7. A cet effet, les moyens de contraintes 11 seront conçus pour assurer une poussée supérieure à celle exercée par les moyens de contraintes 8. Il est à noter que les surfaces en regard des plaques de lissage 5 et 7 définissent la zone de travail de l'appareil A. La différence de friction entre la zone de traction 12 et la zone de travail 13 combinée à un déplacement de l'appareil de lissage à l'opposé du cuir chevelu dans le sens de la flèche F1 induit une mise en tension de la partie de la mèche de cheveux M se trouvant entre le cuir chevelu C et la zone de traction 12 et notamment dans la zone de travail 13. Il est à noter que lors du déplacement de l'appareil la zone de traction 12 exerce sur les cheveux une traction supérieure T12 à celle T13 exercée par la zone de traitement 13. Cette traction T13 contribue à favoriser l'effet lissant de la chaleur appliquée par la plaque de lissage 5 de la deuxième mâchoire 2. Ainsi, cette mise en tension permet d'obtenir un meilleur résultat de lissage que celui qui serait obtenu avec le même appareil en l'absence de la barre de friction 10. Afin d'augmenter plus encore le différentiel de pression et donc de friction entre la zone de travail 13 et la zone de traction 12, la barre de friction 10 et la plaque de lissage 13 de la première mâchoire sont conçues pour qu'en position ouverte, il existe un retrait r entre la surface S1 de la plaque de lissage 7 et la surface de la barre de traction orientée vers la deuxième mâchoire. Le retrait r mesuré parallèlement aux directions N et N' pourra, par exemple, présenter une valeur comprise entre 0,1 mm et 5 mm. Il est à noter que le différentiel de friction entre la zone de travail 13 et la zone de traction peut également être augmenté en adoptant des états de surface et/ou des matériaux différents pour notamment la plaque de lissage 7 et la barre de friction 10.The hairdressing apparatus A thus constituted is implemented in the following manner. When a user wishes to proceed to the smoothing of a lock M of hair, he comes to close the apparatus A on said wick, as shown in FIG. figure 2 . The user will then have made sure to place the friction bar 10 opposite the scalp C with respect to the smoothing plate 7. The friction bar 10 then defines with the part opposite the smoothing plate 5, a traction zone 12 of the lock of hair M. Indeed, the stressing means 11 and 8 are adapted so that the pressure exerted on the hair lock M by the friction bar 10 is greater than that exerted by the smoothing plate 7. For this purpose, the stressing means 11 will be designed to ensure a thrust greater than that exerted by the stressing means 8. It should be noted that the facing surfaces of the smoothing plates 5 and 7 define the working area of FIG. the apparatus A. The difference in friction between the traction zone 12 and the working zone 13 combined with a displacement of the smoothing device opposite the scalp in the direction of arrow F1 induces a tensioning of the part of the wick M hair M between the scalp C and the traction zone 12 and in particular in the working area 13. It should be noted that during the movement of the apparatus the traction zone 12 exerts on the hair a traction T 12 higher than that T 13 exerted by the treatment zone 13. This traction T 13 contributes to promote the smoothing effect of the heat applied by the plate of smoothing 5 of the second jaw 2. Thus, this tensioning provides a better smoothing result than that which would be obtained with the same device in the absence of the friction bar 10. To further increase the differential pressure and therefore friction between the working zone 13 and the traction zone 12, the friction bar 10 and the smoothing plate 13 of the first jaw are designed so that in the open position, there is a withdrawal r between the surface S 1 of the smoothing plate 7 and the surface of the drawbar facing the second jaw. The recess r measured parallel to the directions N and N 'may, for example, have a value of between 0.1 mm and 5 mm. It should be noted that the friction difference between the working zone 13 and the traction zone can also be increased by adopting surface conditions and / or different materials, in particular for the smoothing plate 7 and the friction bar 10.

Bien entendu, selon l'invention, il pourrait être envisagé que les deux mâchoires 1 et 2 portent chacune une barre de friction. Ainsi, la figure 4 illustre une forme de réalisation de l'appareil de coiffure 1 selon laquelle la première et la deuxième mâchoire possèdent une configuration sensiblement symétrique, au moins pour ce qui concerne la région de travail.Of course, according to the invention, it could be envisaged that the two jaws 1 and 2 each carry a friction bar. So, the figure 4 illustrates an embodiment of the hairdressing apparatus 1 in which the first and second jaws have a substantially symmetrical configuration, at least as regards the working region.

Ainsi, selon cet exemple, la plaque de lissage 5 de la deuxième mâchoire 2 est montée sur cette dernière, de manière à être également mobile en translation de direction N. La deuxième mâchoire 2 comprend alors des moyens de contrainte 18 adaptés pour pousser la plaque de lissage 6 en direction de la première mâchoire 1. De la même manière, la deuxième mâchoire 2 comprend alors une contre-barre de friction 20 située en regard de la barre de friction 10, la contre-barre de friction 20 est mobile en translation de direction N' et se trouve poussée vers la première mâchoire 1 et plus particulièrement vers la contre-barre de friction 10 par des moyens de contraintes 21. Il doit être noté que, selon cet exemple, les deux plaques mobiles de lissage 5 et 7 sont chacune associées à des moyens de chauffage respectivement 6 et 22.Thus, according to this example, the smoothing plate 5 of the second jaw 2 is mounted on the latter, so as to be also movable in translation N direction. The second jaw 2 then comprises means of constraint 18 adapted to push the plate in the same way, the second jaw 2 then comprises a counter-friction bar 20 located opposite the friction bar 10, the counter-friction bar 20 is movable in translation. direction N 'and is pushed to the first jaw 1 and more particularly to the counter-friction bar 10 by means of constraints 21. It should be noted that, according to this example, the two movable smoothing plates 5 and 7 are each associated with heating means respectively 6 and 22.

L'appareil de coiffure ainsi constitué s'utilise et de la même manière que décrit précédemment. Il est à noter que les formes de réalisation telles que décrites en relation avec les figures 2 et 3, d'une part, et la figure 4, d'autre part, nécessitent toutes de veiller à placer les barres de frictions à l'opposé du cuir chevelu, de manière à assurer la tension de la partie de la mèche située entre les plaques de lissage dans la zone de travail 13.The hairdressing apparatus thus constituted is used and in the same manner as described above. It should be noted that the embodiments as described in connection with the figures 2 and 3 , on the one hand, and figure 4 , on the other hand, all require to be careful to place the bars of friction opposite the scalp, so as to ensure the tension of the portion of the wick located between the smoothing plates in the working area 13.

Cependant il est possible de s'affranchir de cette obligation d'orientation convenable de l'appareil de coiffure A.However, it is possible to dispense with this obligation of proper orientation of the hairdressing apparatus A.

Ainsi, la figure 5 illustre une autre forme de réalisation de l'appareil de coiffure selon l'invention, dans laquelle la première mâchoire 1 comprend une barre de friction disposée sensiblement au centre de la mâchoire en étant sensiblement alignée par rapport à un plan médian longitudinal de cette dernière. La barre de friction 10 divise alors la plaque de lissage 7 en deux parties égales, respectivement, gauche et droite. Il est à noter que, selon cet exemple, la plaque de lissage 7 de la première mâchoire est fixée de manière rigide sur cette dernière et n'est donc pas mobile, comme cela a été décrit en relation avec les exemples précédents. De la même manière, la deuxième mâchoire 2 présente une conception sensiblement analogue à celle de la deuxième mâchoire 2 de l'appareil décrit en relation avec les figures 2 et 3. La position centrale de la barre de friction 10 permet donc de garantir la tension de la partie de la mèche de cheveux M située entre la barre de friction 10 et le cuir chevelu en étant également dans une partie de la zone de travail 13 délimitée par les parties en regard de la plaque de lissage 5 et de la plaque de lissage 7. Bien entendu, il pourrait être envisagé de réaliser l'appareil de coiffure en mettant en oeuvre pour les deux mâchoires une conception sensiblement analogue à celle de la première mâchoire décrite en relation avec la figure 5. Dans ce cas, il pourrait également être envisagé d'associer chaque demi-plaque de lissage avec des moyens de chauffage électrique.So, the figure 5 illustrates another embodiment of the hairdressing apparatus according to the invention, wherein the first jaw 1 comprises a friction bar disposed substantially in the center of the jaw being substantially aligned with respect to a longitudinal median plane thereof. The friction bar 10 then divides the smoothing plate 7 into two equal parts, respectively, left and right. It should be noted that, according to this example, the smoothing plate 7 of the first jaw is fixed rigidly on the latter and is not mobile, as has been described in connection with the previous examples. In the same way, the second jaw 2 has a design substantially similar to that of the second jaw 2 of the apparatus described in connection with the figures 2 and 3 . The central position of the friction bar 10 therefore makes it possible to guarantee the tension of the part of the lock of hair M situated between the friction bar 10 and the scalp while also being in a part of the working zone 13 delimited by the parts opposite the smoothing plate 5 and the smoothing plate 7. Of course, it could be envisaged to make the hairstyling device by implementing for both jaws a design substantially similar to that of the first jaw described in relation to the figure 5 . In this case, it could also be envisaged to associate each half-smoothing plate with electric heating means.

Les figures 6 à 8 illustrent une autre forme de réalisation de l'appareil de coiffure selon l'invention qui permet également d'assurer une tension adéquate de la mèche de cheveux à traiter indépendamment de l'orientation de l'appareil A par rapport au cuir chevelu.The Figures 6 to 8 illustrate another embodiment of the hairdressing apparatus according to the invention which also ensures adequate tension of the lock of hair to be treated independently of the orientation of the apparatus A relative to the scalp.

Selon cette autre forme de réalisation, la plaque de lissage de la première mâchoire 1 est supportée par un chariot 30 mobile en translation parallèlement à la surface de travail S1. La première mâchoire 1 comprend également deux barres de friction 31 chacune disposées de part et d'autre de la plaque de lissage 7. Chaque barre de friction 31 est alors portée par l'extrémité libre d'un bras 32 dont l'extrémité opposée est articulée sur la mâchoire 1. L'articulation de chacun des bras 32 sur la première mâchoire peut être réalisée de toute façon appropriée comme par exemple sous la forme d'une articulation élastique ou encore une liaison pivot. Selon l'exemple illustré, les bras 32 sont formés par des lames élastiques et leur articulation au niveau de la mâchoire 1 résulte de leurs caractéristiques élastiques. Les bras 32 sont, en outre, disposés de manière à être inclinés vers l'extérieur en direction de la deuxième mâchoire 2. La plaque de lissage 7 est en outre associée à des doigts de traction 33 qui, selon l'exemple illustré, sont portés par le chariot 30. Chaque doigt 33 est alors adapté pour exercer une traction sur le bras 32 correspondant lorsque le chariot 30 se déplace en translation à l'opposé dudit bras. En revanche, chaque doigt 33 est adapté pour ne pas déplacer le bras 32 correspondant lorsque le chariot se déplace en direction de ce dernier.According to this other embodiment, the smoothing plate of the first jaw 1 is supported by a carriage 30 movable in translation parallel to the working surface S 1 . The first jaw 1 also comprises two friction bars 31 each disposed on either side of the smoothing plate 7. Each friction bar 31 is then carried by the free end of an arm 32 whose opposite end is articulated on the jaw 1. The articulation of each of the arms 32 on the first jaw can be made in any suitable manner such as for example in the form of an elastic hinge or a pivot connection. According to the illustrated example, the arms 32 are formed by resilient blades and their articulation at the jaw 1 results from their elastic characteristics. The arms 32 are further arranged to be inclined outwards towards the second jaw 2. The smoothing plate 7 is further associated with traction fingers 33 which, according to the illustrated example, are carried by the carriage 30. Each finger 33 is then adapted to exert traction on the arm 32 corresponding when the carriage 30 moves in translation opposite said arm. In contrast, each finger 33 is adapted not to move the arm 32 corresponding when the carriage moves towards the latter.

Selon l'exemple illustré, la deuxième mâchoire 2 présente une configuration sensiblement analogue à celle de la première mâchoire 1, ainsi, la plaque de lissage 5 est également portée par un chariot 35 mobile en translation parallèlement à la surface de travail S2. La deuxième mâchoire 2 comprend aussi deux contre-barres de friction 36, portée chacune par l'extrémité libre d'un bras articulé sensiblement analogue au bras articulé 32. Le chariot 35 comprend également des doigts de traction 38 ayant une fonction analogue à celle des doigts de traction 33. Enfin, selon cet exemple, chacune des plaques de lissage 5 et 7 est associée avec des moyens de chauffage respectivement 6 et 22.According to the illustrated example, the second jaw 2 has a substantially similar configuration to that of the first jaw 1, thus, the smoothing plate 5 is also carried by a carriage 35 movable in translation parallel to the working surface S 2 . The second jaw 2 also comprises two friction counter-bars 36, each carried by the free end of an articulated arm substantially similar to the articulated arm 32. The carriage 35 also comprises traction fingers 38 having a function similar to that of the traction fingers 33. Finally, according to this example, each of the smoothing plates 5 and 7 is associated with heating means respectively 6 and 22.

L'appareil de lissage ainsi constitué fonctionne de la manière suivante comme cela est illustré plus particulièrement aux figures 7 et 8.The smoothing apparatus thus constituted operates in the following manner, as is illustrated more particularly in FIGS. Figures 7 and 8 .

Lorsque l'appareil de coiffure A est placé, par exemple, à gauche du cuir chevelu C, comme le montre la figure 7, et qu'une traction dans le sens de la flèche F1 est exercée, les plaques de lissage 5 et 7 ont tendance à se déplacer ensemble en sens opposé, tel qu'illustré par les flèches. Cette translation relative, des plaques de lissage 5 et 7 vers la droite par rapport aux mâchoires qui les portent, induit une traction sur les bras gauche 32 et 37 ce qui contribue à rapprocher les barres de frictions gauches 31 et 36 l'une de l'autre, de manière à pincer la mèche de cheveu M. La friction accentuée dans la zone de traction définie par la barre et la contre-barre rapprochées tend la partie de la mèche de cheveux M située entre la zone de traction et le cuir chevelu. Il est à noter que dans cet écart, la barre de traction 31 et la contre-barre de friction correspondante 36 situées à droite ne travaillent pas et n'exercent aucun effort sur la mèche de cheveux.When the hairdressing apparatus A is placed, for example, to the left of the scalp C, as shown in FIG. figure 7 , and that traction in the direction of the arrow F 1 is exerted, the smoothing plates 5 and 7 tend to move together in opposite directions, as illustrated by the arrows. This translation relative, smoothing plates 5 and 7 to the right relative to the jaws that carry them, induces traction on the left arm 32 and 37 which contributes to bringing the left friction bars 31 and 36 from one another in order to pinch the lock of hair M. The accentuated friction in the traction zone defined by the bar and the counter-bar close together tends to the part of the lock of hair M situated between the traction zone and the scalp. It should be noted that in this gap, the drawbar 31 and the corresponding against-friction bar 36 located on the right do not work and exert no effort on the lock of hair.

En cas de configuration inverse, tel qu'illustré à la figure 8, il doit être remarqué que ce sont les barres de frictions droites qui travaillent, tandis que les barres de frictions gauches sont au repos. Il apparaît donc que cette forme de réalisation permet d'avoir un fonctionnement symétrique de l'appareil et affranchit l'utilisateur de devoir prendre en considération le placement de l'appareil par rapport à la mèche de cheveux et au cuir chevelu pour assurer un traitement adéquat.In reverse configuration, as shown in figure 8 it should be noted that the straight bars of friction are working, while the left bars of friction are at rest. It therefore appears that this embodiment makes it possible to have a symmetrical operation of the apparatus and frees the user from having to take into consideration the placement of the apparatus with respect to the lock of hair and the scalp to ensure a treatment. adequate.

Par ailleurs, il doit être remarqué que les différentes formes de réalisation de l'appareil de coiffure selon l'invention, permettent à l'utilisateur d'assurer une tension adéquate des mèches de cheveux à lisser, au seul moyen de l'appareil à coiffure selon l'invention tenu dans une main sans devoir utiliser l'autre main, ce qui facilite l'opération de lissage.Furthermore, it should be noted that the various embodiments of the hairdressing appliance according to the invention allow the user to ensure adequate tension of the locks of hair to be smoothed, by the only means of the apparatus to hairstyle according to the invention held in one hand without having to use the other hand, which facilitates the smoothing operation.

Selon les exemples décrits précédemment en relation avec les figures 1 à 8, chaque barre de friction est mobile par rapport à la surface de travail adjacente selon un mouvement contenu dans un plan perpendiculaire à l'axe longitudinal L de la mâchoire correspondante. Toutefois, selon l'invention un autre type de déplacement des barres de friction pourrait être envisagé.According to the examples described above in relation to the Figures 1 to 8 each friction bar is movable relative to the adjacent working surface in a movement contained in a plane perpendicular to the longitudinal axis L of the corresponding jaw. However, according to the invention another type of displacement of the friction bars could be envisaged.

Ainsi, la figure 9, illustre une autre forme de réalisation de l'appareil de coiffure selon laquelle, la première mâchoire 1 comprend une pluralité de barres de friction 40 qui sont chacune mobiles par rapport à la surface de travail S1 adjacente selon une direction parallèle à l'axe longitudinal L de la première mâchoire 1. Chaque barre de friction forme alors une dent s'étendant selon un plan perpendiculaire à la surface de travail S1 et à l'axe longitudinal. La première mâchoire 1 comprend en outre des moyens manoeuvres, non représentés, destinés à rapprocher les dents les unes des autres lors de la fermeture de l'appareil A de sorte que les dents définissent deux à deux des zones de traction au niveau desquelles les cheveux sont pincés. Il pourrait également être envisagé d'interposer entre chaque dent mobile 40 une contre-dent fixe vers laquelle une des dents mobiles est déplacée lors de la fermeture de l'appareil A pour définir avec la contre-dent correspondante une zone de traction.
La figure 10 représente un exemple de fixation d'une couche de matériau 100 améliorant la tension et/ou le freinage sur la surface de la barre de friction. Cette couche est avantageusement d'épaisseur uniforme, peut présenter une surface destinée à être en contact avec les cheveux substantiellement plane. On a vu que cette couche peut être surmoulée ou sertie ou sur système de glissière sur la barrette de barre de friction 130. La figure 10 représente un mode de fixation par queues de sapin 110 destinées à traverser et se fixer dans au moins deux perçages 120 agencés perpendiculaires à l'axe longitudinal de la barre de friction.
La couche de matériau tenseur rehaussé 100 peut présenter sur les bords longitudinaux un retour pour éviter toute arête dommageable pour les cheveux. Cette couche de matériau tenseur 100 rehaussé peut être appliquée de façon fixe ou de façon amovible pour le remplacement de la couche ou pour revenir à une configuration de lisseur classique sans barre de friction.
La barrette de friction 130 sur laquelle vient se fixer la couche 100 d'élément tenseur rehaussé peut être faite dans un profil extrudé en aluminium ou équivalent.
La combinaison du matériau tenseur rehaussé type silicone avec le montage de la barre de friction mobile augmente exceptionnellement la tension appliquée aux cheveux tout en évitant un endommagement des cheveux.So, the figure 9 , illustrates another embodiment of the hairdressing apparatus in which the first jaw 1 comprises a plurality of friction bars 40 which are each movable relative to the adjacent working surface S 1 in a direction parallel to the axis longitudinally L of the first jaw 1. Each friction bar then forms a tooth extending in a plane perpendicular to the working surface S 1 and the longitudinal axis. The first jaw 1 further comprises maneuvering means, not shown, intended to bring the teeth closer together when closing the apparatus A so that the teeth define two by two traction zones at which the hair is pinched. It could also be envisaged to interpose between each movable tooth 40 a fixed against-tooth to which one of the movable teeth is moved during closing of the apparatus A to define with the corresponding against-tooth a traction zone.
The figure 10 represents an example of fixing a layer of material 100 improving the tension and / or the braking on the surface of the friction bar. This layer is advantageously of uniform thickness, may have a surface intended to be in contact with the hair substantially flat. It has been seen that this layer can be overmolded or crimped or on a slide system on the friction bar bar 130. figure 10 represents a fir tree tying mode 110 for traversing and fixing in at least two bores 120 arranged perpendicular to the longitudinal axis of the friction bar.
The layer of enhanced tensor material 100 may have a longitudinal return to the longitudinal edges to avoid any edge harmful to the hair. This layer of raised tensor material 100 may be fixedly or removably applied for layer replacement or to return to a conventional frictionless straightener configuration.
The friction bar 130 on which is fixed the layer 100 of enhanced tensioning element can be made in an extruded aluminum profile or equivalent.
The combination of the elevated silicone-type tensing material with the mounting of the mobile friction bar exceptionally increases the tension applied to the hair while avoiding damage to the hair.

Par ailleurs, l'appareil de coiffure selon l'invention peut également intégrer, en amont ou en aval de la zone de traction, des moyens d'application des produits cosmétiques sur les cheveux. Le ou les produits appliqués pourront alors être par exemple contenus dans une ou plusieurs cartouches amovibles.Moreover, the hairdressing appliance according to the invention can also incorporate, upstream or downstream of the traction zone, means for applying cosmetic products to the hair. The applied product (s) may then for example be contained in one or more removable cartridges.

De même, afin d'optimiser l'efficacité de la mise en forme, l'appareil de coiffure selon l'invention peut aussi comprendre des moyens de production de vapeur adaptés pour appliquer un flux de vapeur sur les cheveux en amont ou en aval de la zone de traction.Likewise, in order to optimize the efficiency of the shaping, the hairdressing appliance according to the invention may also comprise means of production of steam adapted to apply a flow of steam on the hair upstream or downstream of the traction zone.

Bien entendu, diverses autres modifications peuvent être apportées à l'invention dans le cadre des revendications annexées.Of course, various other modifications may be made to the invention within the scope of the appended claims.
