Description

La présente invention concerne un appareil de coiffure ou de mise en forme des cheveux, plus particulièrement du type à lisser les cheveux, plus particulièrement un appareil comportant un dispositif prévu pour exercer une pression sur la mèche de cheveux à traiter.The present invention relates to a device for hairstyling or shaping the hair, more particularly of the hair straightening type, more particularly an apparatus comprising a device designed to exert pressure on the lock of hair to be treated.

La plupart des appareils de mise en forme des cheveux, tels par exemple les lisseurs, les fers à gaufrer, comportent deux mâchoires pivotantes supportant chacune à une extrémité une surface de traitement dont au moins une est chauffée, l'autre étant prévue pour amener les cheveux en contact avec la première, notamment en passant d'une position d'ouverture des mâchoires permettant l'insertion des cheveux à une position de fermeture pour leur mise en contact avec la partie chauffante. L'autre extrémité des mâchoires forme deux demi poignées faisant office de zone de préhension et permettant de passer de la position d'ouverture à celle de fermeture. Le passage se fait manuellement en pressant les deux demi poignées articulées de l'appareil l'une vers l'autre pour amener la partie chauffante au contact des cheveux.Most hair shaping devices, such as hair straighteners, embossing irons, comprise two pivoting jaws each supporting at one end a treatment surface of which at least one is heated, the other being intended to bring the hair in contact with the first, including passing from an opening position of the jaws allowing the insertion of the hair to a closed position for their contact with the heating part. The other end of the jaws form two half handles acting as a gripping area and to move from the open position to the closing position. The passage is done manually by pressing the two half handles articulated device towards each other to bring the heating part in contact with the hair.

Ces appareils présentent l'inconvénient de nécessiter une pression continue et forte de l'utilisatrice sur les demi poignées pour obtenir un bon résultat de traitement et ceci pendant tout la durée de traitement. Ceci entraîne pour l'utilisatrice une opération fatigante et fastidieuse.These devices have the disadvantage of requiring a continuous and strong pressure of the user on the half handles to obtain a good treatment result and this for the duration of treatment. This entails for the user a tiring and tedious operation.

Le document US 1 522 823 décrit un appareil de coiffure qui a un but de remédier aux inconvénients précités.The document US 1,522,823 describes a hairdressing apparatus which has a purpose of overcoming the aforementioned drawbacks.

On connaît un premier type d'appareil où le point de pivot des mâchoires est agencé entre les demi poignées et les surfaces de traitement. Cet agencement présente l'inconvénient de nécessiter une course angulaire importante des demi poignées pour obtenir une ouverture suffisante des surfaces de traitement nécessaire à l'introduction des mèches de cheveux.A first type of apparatus is known where the pivot point of the jaws is arranged between the half-handles and the treatment surfaces. This arrangement has the disadvantage of requiring a large angular stroke of the half handles to obtain a sufficient opening of the treatment surfaces necessary for the introduction of locks of hair.

On connaît un deuxième type d'appareil où le point de pivot des mâchoires est agencé à extrémité de ces mâchoires, à l'opposé des surfaces de traitement.A second type of apparatus is known where the pivot point of the jaws is arranged at the end of these jaws, opposite the treatment surfaces.

Cet agencement présente une ergonomie améliorée par rapport au premier type d'appareil, en effet, les demi poignées ont une course angulaire plus faible pour obtenir une ouverture suffisante des surfaces de traitement. Cependant, cet agencement présente l'inconvénient de nécessiter une pression importante de l'utilisatrice sur les demi poignées pour obtenir un effort suffisant des surfaces de traitement sur les cheveux, en sachant que l'intensité et la régularité de cet effort intervient de façon importante dans le résultat du traitement obtenu.This arrangement has improved ergonomics compared to the first type of device, in fact, the half handles have a lower angular stroke to obtain sufficient opening of the treatment surfaces. However, this arrangement has the disadvantage of requiring a significant pressure of the user on the half handles to obtain a sufficient effort of the treatment surfaces on the hair, knowing that the intensity and regularity of this effort is important in the result of the treatment obtained.

Le but de la présente invention est de remédier aux inconvénients précités et de proposer un appareil de coiffure apte à réaliser une bonne mise en forme des cheveux tout en étant d'une utilisation aisée, sans nécessiter d'effort particulier en fonctionnement.The object of the present invention is to overcome the aforementioned drawbacks and to provide a hair styling device capable of achieving good shaping of the hair while being easy to use, without requiring any particular effort in operation.

Un autre but de l'invention est un appareil de coiffure qui soit de structure simplifiée, compact et pouvant être industrialisé pour un faible coût.Another object of the invention is a hairdressing appliance which is of simplified structure, compact and can be industrialized for a low cost.

Ces buts sont atteints avec un appareil de coiffure comme décrit dans la revendication 1.These objects are achieved with a hairdressing apparatus as described in claim 1.

Selon l'invention, les surfaces de traitement sont maintenues en pression pour permettre d'appliquer un effort continu sur les cheveux sans intervention de l'utilisatrice. Ainsi, l'introduction des cheveux entre les surfaces de traitement est réalisée par l'utilisatrice en exerçant une pression sur les demi poignées. Ensuite, la mise en forme des cheveux est réalisée uniquement en déplaçant l'appareil, les moyens de rappel des demi poignées mettant les surfaces de traitement en pression, ce qui garantit un effort continu sur les cheveux.According to the invention, the treatment surfaces are maintained under pressure to allow a continuous force to be applied to the hair without the intervention of the user. Thus, the introduction of the hair between the treatment surfaces is performed by the user by exerting pressure on the half handles. Then, the shaping of the hair is carried out only by moving the apparatus, the return means of the half handles putting pressure treatment surfaces, which ensures a continuous effort on the hair.

L'utilisatrice peut également limiter ponctuellement en cours de traitement l'effort sur les cheveux en appliquant une légère pression sur les demi poignées.The user may also temporarily limit the stress on the hair while applying a slight pressure on the half handles.

Cette disposition permet d'obtenir une construction simplifiée de l'appareil pour inverser les mouvements des demi poignées et des surfaces de traitement : la fermeture des demi poignées par une pression de l'utilisatrice provoque une ouverture des surfaces de traitement et l'ouverture des demi poignées sous l'effet des moyens de rappel provoque la fermeture des surfaces de traitement. Ce qui garantit une mise en pression des surfaces de traitement sans intervention de l'utilisatrice.This arrangement makes it possible to obtain a simplified construction of the apparatus for reversing the movements of the half-handles and the treatment surfaces: the closure of the half-handles by pressure of the user causes opening of the treatment surfaces and opening of the half handles under the effect of the return means causes the closing of the treatment surfaces. This ensures that the treatment surfaces are pressurized without the intervention of the user.

De préférence, les moyens de rappel des demi poignées comportent un dispositif de réglage de la mise en pression des surfaces de traitement.Preferably, the return means of the half handles comprise a device for adjusting the pressurization of the treatment surfaces.

Cette disposition permet à l'utilisatrice d'adapter la pression des surfaces de traitement sur les cheveux en fonction de la quantité, de la nature, du type de cheveux disposés entre les surfaces.This arrangement allows the user to adapt the pressure of the treatment surfaces on the hair depending on the amount, the nature, the type of hair disposed between the surfaces.

Avantageusement, les moyens de rappel des demi poignées comportent un ressort de compression.Advantageously, the return means of the half handles comprise a compression spring.

Cette disposition permet de réaliser très simplement les moyens de rappel des demi poignées. Ce type de ressort permet d'obtenir une courbe de variation de l'effort exercé sur les surfaces de traitement en fonction de l'angle d'ouverture des demi poignées de forme linéaire.This arrangement makes it possible to achieve very simply the return means of the half handles. This type of spring makes it possible to obtain a curve of variation of the force exerted on the treatment surfaces as a function of the opening angle of the half-handles of linear shape.

De préférence, les moyens de rappel des demi poignées comportent un ressort spirale travaillant en torsion.Preferably, the return means of the half handles comprise a spiral spring working in torsion.

Ce type de ressort permet d'obtenir une courbe de variation de l'effort exercé sur les surfaces de traitement en fonction de l'angle d'ouverture de forme polynomiale de degré supérieur à 2.This type of spring makes it possible to obtain a curve of variation of the force exerted on the treatment surfaces as a function of the opening angle of polynomial shape of degree greater than 2.

Les deux surfaces de traitement des cheveux sont constituées par deux plaques lisses pour lisser les cheveux.The two hair treatment surfaces consist of two smooth plates to smooth the hair.

Cette disposition permet d'obtenir un appareil de mise en forme qui lisse les cheveux.This arrangement provides a shaping device that smooths the hair.

Chaque mâchoire comprend une partie arrière, c'est-à-dire entre la partie avant et l'articulation, formant une zone de préhension constituée par deux demi poignées 5, 6, une supérieure et une inférieure, de type pince.Each jaw comprises a rear portion, that is to say between the front portion and the hinge, forming a gripping zone formed by two half-handles 5, 6, an upper and a lower, clamp type.

Chaque plaque 10, 11 de lissage renferme un élément chauffant (non représentés sur les figures) qui peut être un élément chauffant électrique du type résistif, à CTP, à infrarouges, etc. alimenté en énergie par un interrupteur recevant l'alimentation du câble principal de l'appareil. L'élément chauffant est placé en étant en contact thermique avec la plaque 10, 11 de lissage pour lui transférer intégralement ses calories. La plaque 10, 11 de lissage est réalisée en un matériau métallique bon conducteur de la chaleur du type aluminium ou ses alliages, cuivre ou ses alliages ou en acier.Each smoothing plate 10, 11 contains a heating element (not shown in the figures) which may be an electrical heating element of the resistive type, CTP, infrared, etc.. powered by a switch receiving power from the main cable of the device. The heating element is placed in thermal contact with the smoothing plate 10, 11 to fully transfer its calories. The smoothing plate 10, 11 is made of a metal material which is a good heat conductor of the aluminum type or its alloys, copper or alloys, or steel.

Chaque mâchoire 2, 3 comporte une zone de croisement 9 entre les extrémités des demi poignées 5, 6 et des boîtiers 7, 8, où les mâchoires 2, 3 ont une section transversale amincie pour conserver une largeur sensiblement constante sur la longueur de l'appareil 1.Each jaw 2, 3 has a crossing zone 9 between the ends of the half handles 5, 6 and housings 7, 8, where the jaws 2, 3 have a thinned cross-section to maintain a substantially constant width along the length of the jaw. device 1.

Un ressort 12 de compression est agencé entre les deux demi poignées 5, 6. Un dispositif de réglage de la mise en pression des surfaces de traitement est constitué par une vis 17 par l'ajustement de la longueur du ressort 12. Le ressort 12 comporte une première extrémité 13 (fig.2) fixée dans un logement 20 ménagé dans la demi poignée 6 inférieure et une seconde extrémité 14 montée coulissante dans un logement 21 ménagé dans la demi poignée 5 supérieure, en appui sur une première extrémité 19 de la vis 17 de réglage. La vis 17 est montée dans une ouverture filetée de la demi poignée 5 supérieure, dans le prolongement du logement 21. La vis 17 comporte une deuxième extrémité formée par un bouton moleté 18 manoeuvrable en rotation par l'utilisatrice.A compression spring 12 is arranged between the two half-handles 5, 6. A device for adjusting the pressurization of the treatment surfaces is constituted by a screw 17 by adjusting the length of the spring 12. The spring 12 comprises a first end 13 ( fig.2 ) fixed in a dwelling 20 formed in the lower half handle 6 and a second end 14 slidably mounted in a housing 21 formed in the upper half handle 5, bearing on a first end 19 of the adjusting screw 17. The screw 17 is mounted in a threaded opening of the upper half handle 5, in the extension of the housing 21. The screw 17 has a second end formed by a knurled knob 18 operable in rotation by the user.

En fonctionnement, après la mise en température de l'appareil 1, l'utilisatrice exerce une pression sur les demi poignées 5, 6, comprimant le ressort 12 pour écarter les plaques 10, 11 de lissage au maximum tel que visible à la figure 3. L'appareil 1 est alors en position ouverte. L'utilisatrice insère une mèche de cheveux entre les plaques 10, 11 de lissage, de préférence en plaçant l'appareil 1 au plus près du cuir chevelu. Puis elle relâche complètement la pression sur les demi poignées 5, 6, ce qui a pour effet, sous la pression du ressort 12, de pincer la mèche de cheveux entre les plaques 10, 11 de lissage. L'utilisatrice déplace ensuite l'appareil 1 le long de la mèche de cheveux, de la racine vers la pointe des cheveux et ceci sans avoir à exercer un effort de pression sur les demi poignées 5, 6 pendant le lissage. L'utilisatrice peut également limiter ponctuellement en cours de traitement l'effort des plaques 10, 11 de lissage sur les cheveux en appliquant une légère pression sur les demi poignées 5, 6, en fin de mèche par exemple.In operation, after warming up the apparatus 1, the user exerts a pressure on the half-handles 5, 6, compressing the spring 12 to move the plates 10, 11 of smoothing to the maximum as visible at the figure 3 . The apparatus 1 is then in the open position. The user inserts a lock of hair between the smoothing plates 10, 11, preferably by placing the device 1 as close as possible to the scalp. Then it completely releases the pressure on the half handles 5, 6, which has the effect, under the pressure of the spring 12, to pinch the lock of hair between the plates 10, 11 of smoothing. The user then moves the device 1 along the lock of hair, from the root to the tip of the hair and this without having to exert a pressure force on the half handles 5, 6 during the smoothing. The user can also limit punctually during treatment the effort of the plates 10, 11 of smoothing on the hair by applying a slight pressure on the half handles 5, 6, end wick for example.

L'utilisatrice peut à tout moment modifier la pression des plaques 10, 11 de lissage sur les cheveux en tournant le bouton moleté 18.The user can at any time change the pressure of the smoothing plates 10, 11 on the hair by turning the knurled knob 18.

Dans une variante non illustrée, le ressort de rappel des demi poignées est un ressort travaillant en torsion comportant un corps en spirale disposé dans l'articulation et deux bras, chacun venant en appui à l'intérieur d'une demi poignée.In a variant not shown, the return spring of the half handles is a torsion spring comprising a spiral body disposed in the joint and two arms, each bearing within a half handle.

Bien entendu, l'invention n'est nullement limitée au mode de réalisation décrit et illustré qui n'a été donné qu'à titre d'exemple. Des modifications restent possibles, notamment du point de vue de la constitution des divers éléments ou par substitution d'équivalents techniques, sans sortir pour autant du domaine de protection de l'invention.Of course, the invention is not limited to the embodiment described and illustrated which has been given by way of example. Modifications are possible, particularly from the point of view of the constitution of the various elements or by substitution of technical equivalents, without departing from the scope of protection of the invention.

Ainsi, les mâchoires peuvent comporter dans la zone de croisement un ou plusieurs axes de rotation permettant de modifier la position angulaire des surfaces de traitement dans une direction longitudinale de l'appareil.Thus, the jaws may include in the crossing zone one or more axes of rotation for changing the angular position of the treatment surfaces in a longitudinal direction of the device.

Dans une autre variante de réalisation, les mâchoires peuvent comporter dans la zone de croisement chacune une biellette reliant la demi poignée à la surface de traitement ainsi qu'un axe de rotation à chaque extrémité de biellette permettant de régler l'ouverture des surface de traitement.In another variant embodiment, the jaws may comprise in the crossing zone each a connecting rod connecting the half-handle to the treatment surface and an axis of rotation at each end of the rod for adjusting the opening of the treatment surfaces. .
