Abstract

The invention can be used particularly for cold perms. The hood comprises two plastic shells (14, 15) joined together in a leaktight manner over their peripheral area which has a contour enabling the hood to be worn so as to frame the client's face, the shells defining an inner volume which is big enough for the client's head to be accommodated therein without coming into contact with the inner shell, and a resistance wire (21) extending freely between the two shells and capable of heating the air cushion (28) enclosed between the two shells. With this hood, the setting time for cold perms is remarkably reduced. <IMAGE>

Description

Casque chauffant pour la coiffure.Heated helmet for hairdressing.

L'invention concerne un casque chauffant pour la coiffure, utilisable notamment pour la réalisation de permanentes.The invention relates to a heated helmet for hairdressing, which can be used in particular for making perms.

Pour fournir à des cheveux une frisure ou ondulation que ceux- ci ne possèdent pas naturellement, les coiffeurs réalisent de façon courante ce qu'on appelle des "permanentes".To provide hair with a curl or waviness that it does not naturally have, hairdressers commonly carry out what is called "perms".

Selon un premier type de permanentes dites "tièdes", les cheveux, séparés en mèches fines, sont enroulés à sec sur des rouleaux ou bigoudis, le liquide à permanente est ensuite appliqué sur toute la surface du crâne, autour de chaque bigoudis, et chacun de ces derniers est alors équipé d'éléments chauffants, par exemple sous forme de manchons élastiques em- boités autour de chaque bigoudis, ces manchons ayant été préalablement chauffés.According to a first type of perm called "lukewarm", the hair, separated into fine strands, is coiled dry on rollers or curlers, the liquid to perm is then applied to the entire surface of the skull, around each curler, and each of these is then fitted with heating elements, for example in the form of elastic sleeves wrapped around each curler, these sleeves having been previously heated.

Cette méthode de réalisation de permanentes nécessite un appareil accessoire coûteux permettant de chauffer individuellement les manchons et, par ailleurs, elle présente le risque d'endommager les cheveux soumis fréquemment à de tels traitements à sec.This method of making perms requires an expensive accessory device for individually heating the sleeves and, moreover, it presents the risk of damaging the hair subjected frequently to such dry treatments.

Une technique de permanentes dites "froides" a donc été mise au point selon laquelle les cheveux encore mouillés après shampoing sont mouillés avec un liquide à permanente approprié, puis séparés en petites mèches fines individuellement enroulées sur des bigoudis, ces derniers recevant une nouvelle"application du liquide à permanente. On place alors sur les bigoudis une feuille de matière plastique très souple dont les extrémités sont assemblées et serrées derrière la nuque, et l'on pose sur la tête de la cliente un bonnet en amiante. On laisse le produit agir pendant une période minimale de l'ordre de 20 à 25 minutes et l'on regarde si les cheveux ont pris la frisure, ce qui nécessite de retirer le bonnet d'amiante, desserrer la feuille de plastique et dérouler un des bigoudis. Si ce n'est pas le cas, on laisse agir un peu plus longtemps le produit et, pour des cheveux ondulant très difficilement, on fait prendre la permanente sous un séchoir à cheveux de type usuel, à pulsation d'air chaud.A technique of so-called "cold" perms has therefore been developed according to which the hair still wet after shampooing is wetted with an appropriate permanent-waving liquid, then separated into small fine strands individually wound. on curlers, the latter receiving a new "application of the perm liquid. then placed on curlers a flexible plastic sheet whose ends are joined and clamped behind the neck, and is placed on the head of the client an asbestos cap. The product is left to act for a minimum period of around 20 to 25 minutes and we check whether the hair has become curled, which requires removing the asbestos cap, loosening the plastic sheet and unroll one of the curlers. If this is not the case, the product is left to act a little longer and, for hair which is wavy very difficult, the perm is taken under a hair dryer of the usual type, pulsating hot air.

De telles permanentes froides présentent l'inconvénient que le temps de traitement peut être relativement long, ce qui est gênant pour la cliente pour laquelle, par ailleurs, la feuille de plastique serrée autour de la tête et le bonnet d'amiante sont difficiles à supporter. Elles nécessitent en outre que le salon de coiffure soit équipé en casques-séchoirs à cheveux auxquels il peut être nécessaire dans certains cas d'avoir recours. Or, on trouve de plus en plus souvent des salons 3e coiffure qui ne possèdent que très peu de tels casques-séchoirs ou qui, même, n'en possèdent pas en raison de la nouvelle mode très répandue de coiffure par brushing.Such cold perms have the disadvantage that the treatment time can be relatively long, which is inconvenient for the client for whom, moreover, the plastic sheet tightened around the head and the asbestos cap are difficult to bear. . They also require that the hairdressing salon be equipped with hair dryer helmets which may in some cases be necessary to have recourse to. However, there are more and more often 3rd hair salons which have very few such dryer hoods or which, even, do not have them because of the new widespread fashion of hairdressing by brushing.

C'est un hut de l'invention de fournir un casque chauffant pour la coiffure, utilisable notamment pour la réalisation de permanentes dites froides, qui permette de réduire fortement le temps nécessaire pour la prise de telles permanentes, qui supprime tout recours aux casques-séchoirs à cheveux usuels et qui soit peu coûteux, permettant ainsi aux coiffeurs d'équiper leurs salons avec un nombre important de tels casques.It is a hut of the invention to provide a heated helmet for hairdressing, usable in particular for the production of so-called permanent perms, which makes it possible to greatly reduce the time necessary for taking such perms, which eliminates any recourse to helmets. conventional and inexpensive hair dryers, allowing hairdressers to equip their salons with a large number of such helmets.

-Le casque chauffant selon l'invention est caractérisé en ce qu'il comprend deux coques en matière plastique reliées entre elles de façon étanche sur leur périphérie, laquelle présente un contour permettant la pose du casque de façon à encadrer le visage d'une cliente, les coques délimitant un volume intérieur suffisamment grand pour que le crâne de la cliente, muni de rouleaux, s'y loge sans venir au contact de la coque intérieure, et en ce qu'il comprend un fil résistant s'étendant librement entre les deux coques, propre à chauffer le coussin d'air enfermé par ces dernières.-The heated helmet according to the invention is characterized in that it comprises two plastic shells connected to each other in a sealed manner on their periphery, which has a contour allowing the helmet to be applied so as to frame the face of a client , the hulls defining an interior volume large enough for the client's skull, fitted with rollers, to lodge there without coming into contact with the inner shell, and in that it comprises a resistant wire extending freely between the two shells, suitable for heating the air cushion enclosed by them.

On a constaté que, grâce au coussin d'air enfermé entre les deux coques, il ne se produit aucun échauffement local du casque, mais que, par contre, le fil résistant chauffe de façon égale tout le volume d'air enfermé, la chaleur étant ainsi diffusée très régulièrement autour du crâne de la cliente. En outre, la chaleur dégagée est humide en raison de la condensation produite, ce qui supprime tous les risques d'endommagement des cheveux dûs à une chaleur sèche.It has been found that, thanks to the air cushion enclosed between the two shells, there is no local heating of the helmet, but that, on the other hand, the resistant wire heats the entire volume of enclosed air equally, the heat thus being distributed very regularly around the skull of the client. In addition, the heat given off is humid due to the condensation produced, which eliminates any risk of damage to the hair due to dry heat.

Avec le casque chauffant selon l'invention, le temps de prise des permanentes froides est notablement réduit. Par exemple, pour les produits à permanentes supportant une température d' environ 45°, le temps de prise, habituellement de l'ordre de 20 à 25 minutes au minimum, est réduit à environ 7 minutes.With the heating helmet according to the invention, the setting time of cold perms is significantly reduced. For example, for products with perms withstanding a temperature of about 45 °, the setting time, usually of the order of 20 to 25 minutes at least, is reduced to about 7 minutes.

Le casque, qui est maintenu en place de façon à encadrer le visage, des moyens de fermeture étant prévus pour appliquer la partie arrière du casque derrière la nuque, ne procure aucune gêne à la cliente.The helmet, which is held in place so as to frame the face, closing means being provided for applying the rear part of the helmet behind the neck, does not cause any discomfort to the client.

De façon avantageuse, le fil résistant est enfermé entre deux feuilles de matière plastique souple, le film résistant ainsi constitué étant fixé par quelques points de soudure soit à la coque intérieure soit à la coque extérieure. Cette caractéristique rend plus facile la fabrication du casque, le film résistant étant maintenu en place sur la coque intérieure par exemple, avant d'appliquer et de souder sur cette dernière la coque extérieure.Advantageously, the resistant wire is enclosed between two sheets of flexible plastic, the resistant film thus formed being fixed by a few welding points either to the inner shell or to the outer shell. This characteristic makes it easier to manufacture the helmet, the resistant film being held in place on the inner shell for example, before applying and welding the outer shell to the latter.

Selon une autre caractéristique importante de l'invention, le casque chauffant comprend une trappe de visite qui, quand soulevée, permet d'accéder à la partie arrière du crâne sans qu'il soit nécessaire de retirer le casque. Après avoir laissé le produit à permanente agir pendant un certain temps, il est alors très facile au coiffeur de soulever la trappe de visite, de dérouler un des bigoudis disposés sur la partie arrière du crâne, éventuellement de réenrouler la mèche si le temps de traitement s'avérait insuffisant, et ce très rapidement, sans procurer aucune gêne à la cliente, étant donné que le casque n'a pas à être enlevé puis remis en place.According to another important characteristic of the invention, the heated helmet includes a inspection hatch which, when raised, allows access to the rear part of the skull without the need to remove the helmet. After leaving the pro due to permanent action for a certain time, it is then very easy for the hairdresser to lift the inspection hatch, to unroll one of the curlers placed on the rear part of the skull, possibly to rewind the lock if the treatment time turns out to be insufficient , and this very quickly, without causing any discomfort to the client, since the helmet does not have to be removed and then replaced.

Les deux coques constitutives du casque chauffant sont avantageusement réalisées en chlorure de polyvinyle, matériau très facile à nettoyer. 1The two shells constituting the heated helmet are advantageously made of polyvinyl chloride, a material very easy to clean. 1

L'invention est décrite ci-après plus en détail, en référence au dessin annexé, dans lequel :

  • La figure est une vue de face d'un casque chauffant selon l'invention.
  • La figure 2 en est une vue par l'arrière.
  • La figure 3 en est une vue en élévation latérale.
  • La figure 4 est une vue en coupe selon la ligne 4-4 de la figure 3.
The invention is described below in more detail, with reference to the accompanying drawing, in which:
  • The figure is a front view of a heating helmet according to the invention.
  • Figure 2 is a rear view.
  • Figure 3 is a side elevational view.
  • Figure 4 is a sectional view along line 4-4 of Figure 3.

Le casque 10 selon l'invention est réalisé en une matière plastique souple mais présentant cependant une rigidité suffisante pour qu'il soit autoportant, c'est-à-dire pour que, lorsqu'il est fixé sur la tête d'une cliente, il puisse se maintenir sans s'affaisser en entourant toute la surface du crâne munie de bigoudis.The helmet 10 according to the invention is made of a flexible plastic material but nevertheless having sufficient rigidity so that it is self-supporting, that is to say so that, when it is fixed on the head of a client, it can be maintained without collapsing by surrounding the entire surface of the skull with curlers.

Par ailleurs, il est de dimensions telles que son volume intérieur est suffisamment grand pour que le crâne de la cliente sur lequel ont été enroulés les bigoudis puisse s'y loger sans venir au contact de la surface intérieure du casque.Furthermore, it is of dimensions such that its interior volume is large enough for the client's skull on which the curlers have been wound to be able to lodge there without coming into contact with the interior surface of the helmet.

Le casque selon l'invention présente, vu de l'avant, une découpe 11, dont le contour correspond sensiblement à l'implantation des cheveux. La partie marginale inférieure du casque se termine à l'arrière par deux pattes 12 et 13 séparées, munies chacune de moyens de fermeture 121, 131, par exemple du type Velcro, qui, lorsque le casque est posé sur la tête de la cliente, assurent la fermeture de ce dernier par coopération mutuelle.The helmet according to the invention has, seen from the front, a cutout 11, the contour of which corresponds substantially to the layout hair. The lower marginal part of the helmet ends at the rear with two separate tabs 12 and 13, each provided with closing means 12 1 , 13 1 , for example of the Velcro type, which, when the helmet is placed on the head of the client, ensure the closure of the latter by mutual cooperation.

Conformément à l'invention, le casque comprend une coque intérieure 14 et une coque extérieure 15 assemblées l'une dans l'autre, ces coques n'étant reliées entre elles, avantageusement par soudure, que sur leur zone périphérique 16.According to the invention, the helmet comprises an inner shell 14 and an outer shell 15 assembled one inside the other, these shells being connected to each other, advantageously by welding, only on their peripheral zone 16.

Chacune des coques 14, 15 peut être réalisée à partir d'une feuille unique, continue, façonnée de façon à conférer au casque la forme souhaitée.Each of the shells 14, 15 can be produced from a single, continuous sheet, shaped so as to give the helmet the desired shape.

Selon une autre réalisation, qui est celle représentée sur les dessins, chacune des coques est réalisée à partir de plusieurs bandes de matériau plastique reliées les unes aux autres par des lignes de soudure. Chaque coque peut ainsi comprendre une bande marginale 17, se terminant sur l'arrière suivant les deux pattes de fermeture 12 et 13, deux bandes latérales 18, 19 et une bande supérieure 20.According to another embodiment, which is that shown in the drawings, each of the shells is produced from several strips of plastic material connected to each other by weld lines. Each shell can thus comprise a marginal band 17, ending on the rear along the two closing tabs 12 and 13, two lateral bands 18, 19 and an upper band 20.

Entre les deux coques intérieure 14 et extérieure 15 est disposé un fil résistant chauffant 21, ce dernier s'étendant librement entre les deux coques, c'est-à-dire sans être fixé ni à l'une ni à l'autre.Between the two inner 14 and outer 15 shells is disposed a resistant heating wire 21, the latter extending freely between the two shells, that is to say without being fixed either to one or the other.

Comme représenté sur le dessin , le fil résistant 21 est disposé suivant des méandres sur. toute la surface du casque, de façon à pouvoir chauffer tout le volume d'air enfermé entre les deux coques 14 et 15.As shown in the drawing, the resistant wire 21 is arranged in meanders on. the entire surface of the helmet, so as to be able to heat the entire volume of air enclosed between the two shells 14 and 15.

Tout dessin du fil résistant autre que celui représenté pourrait être envisagé et, par exemple, on pourrait tout aussi bien réaliser celui-ci sous forme d'un filet qui serait inséré entre les deux coques 14 et 15.Any design of the resistant wire other than that shown could be envisaged and, for example, it could just as easily be produced in the form of a net which would be inserted between the two shells 14 and 15.

Sur le circuit du fil résistant sont avantageusement interposés un thermostat 22, comme visible sur la figure 3, ainsi qu'un fusible thermique 23, lequel est visible sur la figure 2. Les deux extrémités du fil résistant 21 sont assemblées jans une gaine 24 à l'extrémité de laquelle est raccordée une fiche usuelle.On the circuit of the resistant wire are advantageously interposed a thermostat 22, as visible in FIG. 3, as well as a thermal fuse 23, which is visible in FIG. 2. The two ends of the resistant wire 21 are assembled in a sheath 24 to the end of which is connected a usual plug.

Le fil résistant 21 est bien entendu lui-même entouré d'une gaine en matériau isolant.The resistant wire 21 is of course itself surrounded by a sheath of insulating material.

De façon avantageuse, le fil résistant est enfermé entre deux feuilles de matière plastique souple soudées l'une à l'autre, le film résistant ainsi constitué étant maintenu par quelques points de soudure soit à la coque intérieure, soit à la coque extérieure. Une telle réalisation est particulièrement avantageuse du point de vue technique de fabrication du casque, le film résistant, lors de l'assemblage, pouvant être maintenu par exemple par la coque intérieure, sans possibilité de déplacement relatif, cette dernière étant ensuite appliquée contre la coque extérieure et finalement les deux coques soudées l' une à l'autre sur toutes leurs zones périphériques.Advantageously, the resistant wire is enclosed between two sheets of flexible plastic material welded to each other, the resistant film thus formed being held by a few welding spots either on the inner shell or on the outer shell. Such an embodiment is particularly advantageous from the technical point of view of manufacturing the helmet, the resistant film, during assembly, being able to be maintained for example by the inner shell, without the possibility of relative displacement, the latter then being applied against the shell exterior and finally the two shells welded to each other on all their peripheral zones.

Comme visible sur les figures 2 et 3, le casque selon l'invention est découpé sur l'arrière suivant une trappe de visite 25, laquelle peut être relevée ou rabaissée suivant la double flèche 26 par pivotement autour d'une ligne de courbure 27. Cet- trappe permet d'accéder aux bigoudis sur lesquels sont enroulés les cheveux tout en laissant le casque en place sur la tête de la cliente. Elle est avantageusement de dimensions suffisantes pour libérer, lorsqu'elle est relevée, un espace permettant au coiffeur d'introduire ses doigts et de dérouler une des mèches de cheveux enroulés. Le coiffeur peut ainsi vérifier, sans qu' il soit nécessaire de retirer le casque, si le produit à permanente a agi suffisamment longtemps pour conférer aux cheveux 1' ondulation souhaitée.As can be seen in FIGS. 2 and 3, the helmet according to the invention is cut out on the rear following an inspection hatch 25, which can be raised or lowered according to the double arrow 26 by pivoting around a line of curvature 27. This hatch allows access to the curlers on which the hair is wound while leaving the helmet in place on the client's head. It is advantageously of sufficient dimensions to release, when it is raised, a space allowing the hairdresser to introduce his fingers and to unwind one of the strands of coiled hair. The hairdresser can thus check, without the need to remove the helmet, whether the perm product has acted long enough to give the hair the desired waviness.

La trappe de visite 25 est avantageusement ménagée dans la partie du casque se trouvant au droit de la partie arrière du crâne, sensiblement au-dessus de la nuque, les cheveux implantés dans cette partie étant généralement ceux qui acquièrent le plus difficilement une ondulation non naturelle.The inspection hatch 25 is advantageously provided in the part of the helmet located at the level of the rear part of the skull, substantially above the neck, the hair implanted in this part being generally those which acquire the most difficulty an unnatural undulation.

Grâce à.l'existence d'un coussin d'air continu 28 entre les deux coques 14 et 15 sur toute la surface du casque selon l'invention, la chaleur fournie par le fil résistant est dissipée très régulièrement. En outre, du fait qu'il n'y a aucun apport d'air autour du crâne lorsque le casque est mis en place, la chaleur dégagée dans le volume qu'enferme le casque est humide, ce qui supprime tout risque d'endommagement des cheveux.Thanks to the existence of a continuous air cushion 28 between the two shells 14 and 15 over the entire surface of the helmet according to the invention, the heat supplied by the resistant wire is dissipated very regularly. In addition, because there is no air supply around the skull when the helmet is put on, the heat given off in the volume that the helmet encloses is humid, which eliminates any risk of damage. hair.

Le casque selon l'invention permet ainsi, par apport de chaleur, d'activer la réaction chimique du produit à permanente sur les cheveux, et de diminuer notablement le temps de prise.The helmet according to the invention thus makes it possible, by adding heat, to activate the chemical reaction of the product to perm on the hair, and to significantly reduce the setting time.

Alors que le temps de prise des permanentes froides est habituellement au minimum de 20 à 25 minutes, le casque chauffant selon l'invention permet la prise des permanentes froides en une période aussi courte que 7 minutes.While the setting time of cold perms is usually at least 20 to 25 minutes, the heating helmet according to the invention allows setting of cold perms in a period as short as 7 minutes.

La matière plastique constitutive du casque est avantageusement du chlorure de polyvinyle. Bien qu'on puisse utiliser une matière plastique opaque, il est avantageux de réaliser le casque en matière transparente, le coiffeur ayant ainsi la possibilité de vérifier d'un simple regard le bon maintien en position des rouleaux sur lesquels sont enroulés les cheveux.The plastic material of the helmet is advantageously polyvinyl chloride. Although an opaque plastic material can be used, it is advantageous to make the helmet from transparent material, the hairdresser thus having the possibility of checking with a simple glance the good holding in position of the rollers on which the hair is wound.

L'application du casque selon l'invention n'est nullement limitée aux permanentes. Comme autre application, on peut mentionner, sans que ceci ne soit nullement limitatif, la réalisation de mèches de cheveux décolorées, la réalisation de teintures et, d'une manière générale, tout traitement de cheveux nécessitant un temps de prise relativement long. La chaleur uniforme, humide, dégagée par le casque selon l'invention permet en effet de réduire de façon notable les temps de prise.The application of the helmet according to the invention is in no way limited to perms. As another application, it can be mentioned, without this being in no way limiting, the production of bleached strands of hair, the production of dyes and, in general, any hair treatment requiring a relatively long setting time. The uniform, humid heat given off by the helmet according to the invention in fact makes it possible to significantly reduce setting times.
