Description

La présente invention concerne un dispositif qui permet dans le mêmeThe present invention relates to a device which allows in the same

temps, lors d'un rasage électrique, de détruire le follicule pileux et de couper le poil. Les rasoirs électriques traditionnels utilisent généralement une grille de protection du bloc de lames qui coupe exclusivement les poils. Ils n'empêchent pas la repousse, car ils n'agissent pas sur les racines. La présente invention a pour but de remédier à cet inconvénient. Le procédé selon l'invention consiste lorsque l'on passe le rasoir sur la zone à épiler, à diffuser un courant électrique par électrolyse sur le poil pour '10 atteindre sa papille et sa racine, juste avant de le couper avec la grille. Grâce à ce procédé simultané, la racine du poil est détruite, le poil est enlevé et sa repousse est considérablement ralentie. Le dispositif à mettre en place pour la réalisation du dit procédé comporte en effet selon une première caractéristique, un support de grille 45 avec des coussinets métalliques. Celui-ci est constitué de deux coussinets conducteurs diffusant un courant électrique, placés devant et derrière la grille de rasage. Ainsi, quand l'utilisatrice(teur) passe l'appareil sur la zone à épiler, le coussinet conducteur avant qui est relié au générateur interne glisse le premier sur le poil et par contact, transmet le courant. La grille passe ensuite 2.0 sur le poil et le coupe. Selon des modes particuliers de réalisation : le support de grille peut comporter deux coussinets : un coussinet avant relié positivement, pour la diffusion du courant et un coussinet arrière relié négativement, pour le retour du courant. 2.5 - le support de grille peut comporter que le coussinet avant relié positivement. Le retour du courant est assuré par une partie métallique reliée négativement et fixée sur la face extérieure du boîtier, afin d'être en contact avec la main. Dans les deux cas, la résistance du corps est au même potentiel que le générateur interne et l'électrolyse circule parfaitement.  time, during an electric shave, to destroy the hair follicle and cut the hair. Traditional electric razors typically use a blade block guard that cuts hair exclusively. They do not prevent regrowth because they do not act on the roots. The present invention aims to overcome this disadvantage. The method according to the invention consists in passing the razor over the area to be depilated, diffusing an electric current by electrolysis on the hair to reach its papilla and its root, just before cutting it with the grid. Thanks to this simultaneous process, the root of the hair is destroyed, the hair is removed and its regrowth is considerably slowed down. The device to be put in place for carrying out said method comprises, according to a first characteristic, a grid support 45 with metal bearings. This consists of two conductive pads diffusing an electric current, placed in front of and behind the shaving foil. Thus, when the user passes the device over the area to be depilated, the front conductive pad which is connected to the internal generator slides first on the hair and by contact, transmits the current. The grid then passes 2.0 on the hair and the cut. According to particular embodiments: the grid support may comprise two bushings: a positively connected front bushing, for the diffusion of the current and a negatively connected rear bushing, for the return of the current. 2.5 - The grid support may include that the front bearing connected positively. The current is restored by a metal part negatively connected and fixed on the outer face of the housing, in order to be in contact with the hand. In both cases, the resistance of the body is at the same potential as the internal generator and the electrolysis circulates perfectly.

30 Les dessins annexés illustrent l'invention : La figure 1 représente, vu de dessus, le dispositif de l'invention et la figure 2 représente la vue en coupe. La figure 3 représente, vu de dessus, une variante de ce dispositif. En référence aux dessins des figures 1 et 2, le dispositif comporte un 35 support de grille 1 qui se fixe sur le boîtier 5, figure 4. Ce support 1 est muni de deux coussinets alignés parallèlement. A l'avant est positionné le coussinet conducteur positif 3 et à l'arrière est positionné le coussinet conducteur négatif de retour de courant 4, séparés par la grille de rasage 2. La figure 6 représente, vu de dessus, la fixation du support 1 sur le 40 boîtier 5. Ce dernier comporte au centre, sur un axe pivotant, le bloc de lames de coupe 7 et à ses extrémités, deux crochets métalliques de contact 8 et 9, servant au maintien du support 1 et à sa liaison électrique avec les coussinets. La figure 7 illustre la vue de dessus du support 1. Il possède une encoche alignée au centre de chaque extrémité.The accompanying drawings illustrate the invention: Figure 1 shows, from above, the device of the invention and Figure 2 shows the sectional view. 3 shows, seen from above, a variant of this device. With reference to the drawings of FIGS. 1 and 2, the device comprises a grid support 1 which is fixed on the housing 5, FIG. 4. This support 1 is provided with two bearings aligned in parallel. At the front is positioned the positive conductive pad 3 and at the rear is positioned the negative conductor back current pad 4, separated by the shaving foil 2. Figure 6 shows, seen from above, the attachment of the support 1 on the housing 5. The latter comprises in the center, on a pivoting axis, the block of cutting blades 7 and at its ends, two metal contact hooks 8 and 9, for holding the support 1 and its electrical connection with the pads. Figure 7 illustrates the top view of the support 1. It has a notch aligned in the center of each end.

45 Les figures 8 et 9 précisent la réalisation des coussinets conducteurs 3 et 4. Ils sont identiques et ils sont placés en opposition sur le support 1. 2911083 -2- Les coussinets sont constitués d'une plaquette métallique de faible épaisseur. L'ergot centré à une extrémité permet la fixation sur le support. La partie repliée en angle droit à l'autre extrémité est placée dans l'encoche du support, pour assurer la liaison électrique avec le crochet 8 ou 9.Figures 8 and 9 specify the production of conductive pads 3 and 4. They are identical and they are placed in opposition on the support 1. 2911083 -2- The pads consist of a thin metal plate. The lug centered at one end allows attachment to the support. The portion bent at right angles to the other end is placed in the notch of the support, to ensure the electrical connection with the hook 8 or 9.

5 A titre d'exemple non limitatif, les coussinets auront une longueur de l'ordre de 35 mm et une largeur de 5 mm. La figure 10 représente, en coupe, la liaison électrique des coussinets conducteurs positif 3 et négatif 4. Les crochets de contact 8 et 9 sont reliés au générateur interne 10 et restent en contact permanent avec les coussinets 40 correspondant. La transmission du courant se fait par simple frottement. La figure 11 représente le schéma synoptique de l'ensemble mécanique et électronique. L'intérêt du dispositif consiste à bien placer en premier, dans le sens du déplacement du rasoir, le coussinet conducteur positif, afin de permettre 45 l'électrolyse du poil avant de le couper. Selon la variante de réalisation illustrée par la figure 3, le support 1 est muni de la grille de rasage positionnée à l'arrière, mais à l'avant et sur une plus grande largeur, il n'y a que le coussinet conducteur positif 3. Dans ce cas, la figure 5 montre que la plaque métallique 6, fixée 2.0 extérieurement sur le boîtier 5, assure bien le contact négatif de retour du courant. 5 '10 /15 Z0By way of non-limiting example, the pads will have a length of the order of 35 mm and a width of 5 mm. FIG. 10 represents, in section, the electrical connection of the positive and negative conductive pads 4. The contact hooks 8 and 9 are connected to the internal generator 10 and remain in permanent contact with the corresponding pads 40. Current transmission is by simple friction. Figure 11 shows the block diagram of the mechanical and electronic assembly. The advantage of the device is to place first, in the direction of movement of the razor, the positive conductive pad, to allow 45 the electrolysis of the hair before cutting. According to the variant embodiment illustrated in FIG. 3, the support 1 is provided with the shaving foil positioned at the rear, but at the front and over a greater width there is only the positive conductive pad 3 In this case, FIG. 5 shows that the metal plate 6, fixed externally on the housing 5, provides the negative feedback contact of the current. 5 '10 / 15 Z0
