Description

La présente invention est relative à un appareil à épiler à pinces d'arrachage susceptible d'être tenu à la main et destiné à éliminer les poils superflus du corps humain.The present invention relates to a tweezers with pliers of tearing likely to be hand-held and intended to eliminate unwanted hair from human body.

On connaít par exemple par le brevet EP0147285 les épileurs qui comportent des pinces sous forme de lames ou de disques disposés sur un rouleau rotatif, les pinces étant amenées à se fermer et s'ouvrir périodiquement de manière à serrer les poils à proximité de la peau pour les arracher de par la rotation du rouleau et, respectivement, d'évacuer les poils arrachés.For example, patent EP0147285 discloses epilators which comprise pliers in the form of blades or discs arranged on a rotating roller, the tongs being caused to close and open periodically so as to tighten the hairs near the skin to tear them off by the rotation of the roll and, respectively, to evacuate the torn hairs.

Ces appareils par l'action localisée de leur rouleau ne permettent pas de traiter des surfaces importantes d'un coup. Par ailleurs la disposition habituelle des cames de commande en bout de rouleau ne laisse pas beaucoup de place aux rampes de ces cames pour se développer, de sorte qu'elles ont de fortes pentes. Ceci limite les vitesses périphériques des rouleaux et une grande vitesse d'arrachage favorable à une moindre douleur est difficile à obtenir.These devices by the localized action of their roll do not allow to treat large areas at once. Moreover, the usual arrangement of control cams at the end of the roller does not leave much room for ramps of these cams to grow, so they have strong slopes. This limits the peripheral speeds of the rollers and a large Tearing speed favorable to a lesser pain is difficult to obtain.

On connaít par exemple par le brevet FR2646065 les épileurs dont les bords libres des lames d'arrachage oscillent le long d'une surface sensiblement plane.For example, patent FR2646065 discloses epilators whose edges are free tearing blades oscillate along a substantially plane.

Mais les lames étant en contact permanent avec la peau, les poils arrachés ont des difficultés à se dégager de la zone de pincement, ce qui encombre les lames et diminue l'efficacité de l'appareil.But the blades being in permanent contact with the skin, the torn hairs have difficulties in clearing the pinch zone, which blades and decreases the efficiency of the device.

On connaít par exemple par le brevet US5254124 les épileurs dont les pinces sont en bout d'un disque ou d'un cylindre.For example, US Pat. No. 5,254,124 discloses epilators whose pliers are at the end of a disc or a cylinder.

Mais dans ce type d'appareil les pinces sont aussi en contact permanent avec la peau et les poils arrachés sont difficilement évacués.But in this type of device the clamps are also in permanent contact with the skin and torn hairs are hardly evacuated.

On connaít les épileurs à bande tel que celui décrit dans le brevet FR2631528. Dans ce document une courroie est en contact de pression sur plusieurs rouleaux de petit diamètre qu'elle entraíne en rotation. Les petits rouleaux disposés parallèlement définissent une zone d'épilation qui peut être plane. Les poils qui s'engagent entre la bande et les rouleaux sont arrachés par le mouvement de la courroie.We know the tape depilators such as that described in the patent FR2631528. In this document a belt is in pressure contact on several rollers of small diameter that it drives in rotation. Small rolls arranged in parallel define a hair removal zone which can be flat. The bristles that engage between the tape and the rollers are torn off by the belt movement.

Mais le pincement des poils s'effectuant entre la bande et les rouleaux, ce pincement est quelque peu éloigné de la peau qui s'étire ce qui provoque des douleurs à l'arrachage des poils. Par ailleurs les poils arrachés ont tendance à s'enrouler autour des petits rouleaux, diminuant l'efficacité de l'appareil qu'il est difficile de nettoyer.But the pinching of the hairs taking place between the band and the rollers, this pinching is somewhat removed from the skin that stretches which causes pains in pulling hair. Moreover, torn hairs tend to wrap around the small rolls, decreasing the efficiency of the device it is difficult to clean.

Le but de la présente invention est un épileur à pinces d'arrachage, les pinces étant périodiquement dégagées de la peau pouvant comporter plusieurs fenêtres d'arrachage susceptibles d'être utilisées pour des zones restreintes de la peau ou pour des zones larges de la peauThe purpose of the present invention is an epilator with pliers, pliers being periodically free of skin that may contain several tear-off windows that can be used for restricted areas of skin or for wide areas of the skin

Ces buts sont atteints avec un appareil à épiler comportant un boítier, un moteur électrique mettant en mouvement une tête d'épilation à pinces d'arrachage, la partie mobile de la tête étant supportée par deux flasques latéraux, chaque pince comprenant au moins une lame mobile actionnée par des moyens mécaniques pour obtenir la fermeture ou l'ouverture des pinces, lesdits moyens mécaniques comprenant dans au moins un flasque des premiers moyens de commande faisant office de came et sur la partie mobile de la tête d'épilation des seconds moyens d'actionnement recevant le mouvement dû à la came et le transmettant aux lames mobiles, les pinces étant rappelées dans une position d'ouverture ou de fermeture par des moyens élastiques, du fait que les pinces à épiler situées sur une même génératrice, ainsi que leurs moyens d'actionnement et leurs moyens élastiques, sont montés dans un support commun avec lequel ils forment un module, et du fait que les modules sont articulés entre eux côte à côte et forment une chaíne.These goals are achieved with a depilatory device comprising a housing, a electric motor moving a pliers hair removal head the moving part of the head being supported by two flanges lateral members, each clamp comprising at least one movable blade actuated by mechanical means for closing or opening the tongs, said mechanical means comprising in at least one flange of first control means acting as a cam and on the moving part of the epilation head of the second actuating means receiving the movement due to the cam and transmitting it to the moving blades, the clamps being recalled in an open or closed position by means elastic, because the tweezers on the same generator, as well as their actuating means and their elastic means, are mounted in a common medium with which they form a module, and the fact that modules are articulated together side by side and form a chain.

Dans ce qui suit, pour simplifier, on entend, par surface enveloppe, une surface réglée enveloppant la tête d'épilation et qui est générée par une droite se déplaçant en translation ou en rotation ou par une combinaison des deux mouvements.In what follows, for simplicity, is meant, by envelope surface, a surface set wrapping the epilation head and that is generated by a straight line moving in translation or in rotation or by a combination of both movements.

Cette conception modulaire de la tête d'épilation permet la réalisation de nombreuses variantes d'appareils. Par exemple, en changeant le nombre de modules on change le nombre de pinces et on peut faire varier la taille de la tête d'épilation. Chaque module peut ne comporter qu'un faible nombre de lames, ce faible nombre étant compensé par un nombre plus important de modules. La zone d'épilation peut avoir un profil quelconque. Un seul outil de fabrication est nécessaire pour obtenir différentes versions d'appareils.This modular design of the epilation head allows the realization of many device variants. For example, by changing the number of modules we change the number of clamps and we can vary the size of the head hair removal. Each module may have only a small number of blades, this low number being compensated by a larger number of modules. The Hair removal area can have any profile. Only one manufacturing tool is necessary to obtain different versions of devices.

Dans une première version, les seconds moyens d'actionnement comportent des poussoirs agissant sur les lames mobiles en prenant appui sur la surface de travail de cames solidaires des flasques latéraux, cette surface de travail étant sensiblement parallèle aux flasques et comportant des protubérances.In a first version, the second actuating means comprise pushers acting on the movable blades resting on the surface working cams solidarity side flanges, this work surface being substantially parallel to the flanges and having protuberances.

Dans une version préférentielle, les premiers moyens de commande sont des cames dont la surface de travail est perpendiculaire aux flasques et les seconds moyens d'actionnement comportent un renvoi de mouvement transformant le mouvement initial sensiblement parallèle aux flasques dû aux premiers moyens en un mouvement des lèvres de lames mobiles sensiblement perpendiculaire aux flasques.In a preferred version, the first control means are cams whose working surface is perpendicular to the flanges and the second actuating means comprise a movement transfer transforming the initial movement substantially parallel to the flanges due to first means in a movement of the movable blade lips substantially perpendicular to the flanges.

Cette disposition évite d'induire des efforts tendant à déplacer la partie mobile de la tête d'épilation, à écarter les flasques et susceptibles de solliciter mécaniquement la structure de l'appareil.This arrangement avoids inducing efforts to move the moving part the hair removal head, to remove the flanges and likely to solicit mechanically the structure of the device.

La surface de travail des cames étant perpendiculaire aux flasques, les efforts principaux exercés sur cette surface sont parallèles aux flasques et ne tendent pas à les écarter.The working surface of the cams being perpendicular to the flanges, the efforts The main forces exerted on this surface are parallel to the flanges and do not not to dismiss them.

De préférence le renvoi de mouvement est un levier pivotant autour d'un axePreferably the movement return is a lever pivoting about an axis

L'utilisation d'un levier permet le renvoi du mouvement. La lèvre d'une lame mobile se déplace parallèlement à la peau, et l'extrémité du levier se déplace sensiblement dans un plan parallèle aux flasques. Les efforts longitudinaux de serrage des pinces sont équilibrés par l'axe de rotation appartenant à la partie mobile de la tête d'épilation. Par ailleurs l'utilisation d'un levier permet d'amplifier le mouvement de la pince et de diminuer les efforts sur la came de commande. Les mouvements, étant amplifiés, deviennent grands devant les tolérances de fabrication des pièces et les jeux, ainsi que devant l'usure. La fiabilité de l'appareil est augmentée.The use of a lever allows the movement to be returned. The lip of a blade mobile moves parallel to the skin, and the end of the lever moves substantially in a plane parallel to the flanges. The longitudinal efforts of tightening of the clamps are balanced by the axis of rotation belonging to the part mobile hair removal head. In addition, the use of a lever allows to amplify the movement of the clamp and to reduce the forces on the cam of ordered. The movements, being amplified, become big in front of manufacturing tolerances of parts and games, as well as wear. The Reliability of the device is increased.

De préférence l'appareil comporte autant de moyens d'actionnement qu'il y a de lames mobiles auxquelles ils sont respectivement associés, ces seconds moyens étant actionnés par les mêmes premiers moyens de commande.Preferably the apparatus comprises as many actuating means as there are mobile blades with which they are respectively associated, these second means being actuated by the same first control means.

Les lames mobiles étant actionnées indépendamment les unes des autres, une pince encombrée n'affecte pas le serrage des autres pinces. L'efficacité est augmentée. Les efforts sur chaque moyen d'actionnement sont faibles, le moteur est sollicité régulièrement et la durée de vie est augmentée.The movable blades being operated independently of each other, a crowded clamp does not affect the clamping of the other clamps. The effectiveness is increased. The forces on each actuating means are small, the motor is regularly requested and the service life is increased.

De préférence chaque lame mobile est associée à un levier faisant avec ce dernier un sous ensemble monobloc pivotant autour d'un axe.Preferably each movable blade is associated with a lever doing with it last one subassembly monobloc pivoting about an axis.

Chaque lame est alors mobile en oscillation autour de l'axe. La construction est très simple, robuste, et ne nécessite qu'un jeu de fonctionnement facilement contrôlable. Dans une variante, l'extrémité du levier comporte un galet pour limiter le frottement sur la came de commande.Each blade is then movable in oscillation about the axis. The construction is very simple, robust, and requires only a game of operation easily controllable. In a variant, the end of the lever comprises a roller for limit friction on the control cam.

Dans une autre version, les lames mobiles dont les lèvres sont situées sur une même génératrice de la surface enveloppe de la tête d'épilation, sont associées à au moins une coulisse.In another version, the movable blades whose lips are located on a same generator of the envelope surface of the epilation head, are associated with at least one slide.

La coulisse se déplace perpendiculairement aux flasques et entraíne les lames mobiles dans une oscillation autour du pied de chaque lame ou dans une translation.The slide moves perpendicularly to the flanges and drives the blades moving in an oscillation around the foot of each blade or in a translation.

De préférence les pinces sont normalement fermées sous l'action d'un moyen élastique tel qu'un ressort et les moyens mécaniques agissent pour ouvrir les pinces.Preferably the tongs are normally closed by means of a means such as a spring and the mechanical means act to open the pliers.

Les pinces étant fermées sous l'action d'un ressort, la pression de serrage des poils est constante dans le temps et bien maítrisée sans que des réglages soient nécessaires au montage ou pendant l'utilisation. Elle ne dépend pas de la course des lames ni du degré d'usure des moyens mécaniques d'ouverture, la fiabilité est augmentée. L'effort de fermeture des pinces par le ressort est déterminé de manière à assurer un serrage optimum permettant de bien saisir tous types de poils, sans pour autant les couper lors de l'arrachage.The clamps being closed under the action of a spring, the clamping pressure of the hair is constant over time and well controlled without any adjustments necessary for assembly or during use. It does not depend on the stroke of the blades and the degree of wear of the mechanical means of opening, reliability is increased. The closing force of the clamps by the spring is determined in such a way as to ensure optimum tightening all types of hair, without cutting them when pulling.

A l'ouverture des pinces les moyens mécaniques agissent à l'encontre du ressort de serrage dont l'effort est sensiblement constant. Les efforts d'ouverture mis en jeu sont donc parfaitement contrôlés. L'ouverture des pinces peut être relativement lente permettant des pentes modérées sur les cames et autorisant des vitesses linéaires importantes des pinces. La fermeture sous l'action des ressorts peut être brutale, les poils sont alors saisis et arrachés franchement ce qui minimise la douleur.At the opening of the clamps the mechanical means act against the clamping spring whose force is substantially constant. The efforts therefore, are perfectly controlled. The opening of the tongs can be relatively slow allowing moderate slopes on the cams and allowing large linear speeds of the clamps. Closing under the action of the springs can be brutal, the hairs are then seized and torn off frankly which minimizes the pain.

Les ressorts peuvent s'appliquer directement contre la pince mobile ou sur une pièce des moyens d'actionnement telle que la coulisse ou le levier.The springs can be applied directly against the moving clamp or on a part of the actuating means such as the slide or the lever.

De préférence les pinces s'ouvrent dans une région qui n'est pas utilisée lors de l'épilation.Preferably the clamps open in a region that is not used during hair removal.

Cette disposition permet l'évacuation des poils arrachés hors de la zone d'épilation.This arrangement allows the removal of torn hairs out of the zone hair removal.

De préférence les pinces sont décalées latéralement de façon à ce que d'une pince d'une génératrice à celle de la suivante les zones de pincement se complètent au dessus de la surface à épiler.Preferably the clips are laterally offset so that a clip from one generator to that of the next the pinch areas get complete above the surface to be depilated.

En décalant la zone de pincement des pinces qui se présentent successivement on obtient un balayage complet de la zone à épiler.By shifting the pinching area of the clamps that present themselves successively we obtain a complete scan of the area to be depilated.

De préférence, les pinces étant réparties sur des génératrices différentes de la partie mobile de la tête d'épilation, deux pinces sont disposées sur chaque génératrice concemée.Preferably, the clamps being distributed on different generators of the moving part of the epilation head, two clamps are arranged on each generator concerned.

Cette disposition limite le nombre de pinces par module ce qui limite les efforts sur les cames. Le mouvement plus doux peut être plus rapide.This arrangement limits the number of clamps per module which limits the efforts on the cams. The milder movement can be faster.

De préférence les deux pinces d'arrachage sont fermées simultanément au moment de leur passage dans la zone à épiler.Preferably the two pulling tongs are simultaneously closed at moment of their passage in the area to be depilated.

Les pinces peuvent être actionnées chacune par une came située dans un flasque et dans l'autre.The clamps can be each actuated by a cam located in a flaccid and in the other.

Avantageusement la tête d'épilation comporte une fenêtre d'épilation située sur une partie plane ou légèrement bombée de sa surface enveloppe, la fenêtre comportant plusieurs zones de fermeture des pinces.Advantageously, the epilation head has a hair removal window located on a flat or slightly convex part of its envelope surface, the window having a plurality of gripper closing zones.

On obtient ainsi facilement l'épilation sur une zone étendue de la peau.Hair removal is thus easily obtained over a wide area of the skin.

Avantageusement la tête d'épilation comporte une fenêtre d'épilation située sur une partie à forte courbure de sa surface enveloppe. Advantageously, the epilation head has a hair removal window located on a part with a strong curvature of its envelope surface.

L'appareil permet alors l'épilation précise de zones étroites de la peau.The device then allows the precise hair removal of narrow areas of the skin.

Avantageusement la partie mobile de la tête d'épilation présente une section enveloppe dont un côté est rectiligne ou légèrement bombé et relié à un autre côté par une portion de forte courbure.Advantageously, the moving part of the epilation head has a section envelope with one side straight or slightly domed and connected to another side by a portion of strong curvature.

La section peut être oblongue, elliptique, ovale ou prendre une forme triangulaire aux angles arrondis. Elle peut être conçue selon toutes les possibilités que permet une chaíne.The section can be oblong, elliptical, oval or take a shape triangular with rounded corners. It can be designed according to all possibilities that allows a chain.

Ces formes permettent de placer des zones de pincement où l'arrachage se produit dans des conditions différentes appropriées à des usages différents. Elles permettent aussi d'allonger la chaíne en augmentant le nombre de modules, ce qui nécessite moins de pinces par module en permettant un mouvement plus doux et plus rapide.These shapes make it possible to place pinching areas where the pulling is produced under different conditions appropriate for different uses. They also allow to lengthen the chain by increasing the number of modules, which requires fewer clamps per module, allowing softer and faster movement.

De préférence la tête d'épilation comporte une région comportant plusieurs bandes de pincement perpendiculaires aux flasques où les pinces se ferment, et une région d'étendue réduite comportant une seule bande de pincement où les pinces se ferment, les régions étant susceptibles d'être appliquées sur la peau selon respectivement une zone étendue et une zone d'étendue réduite.Preferably, the epilation head comprises a region comprising several pinch strips perpendicular to the flanges where the clamps close, and a reduced extent region having a single pinch strip where the clamps close, the regions being likely to be applied on the skin respectively according to an extended area and a reduced extent area.

Avec un appareil prévu avec une première fenêtre d'épilation pour épiler des zones restreintes de la peau et une deuxième fenêtre prévue pour épiler des zones plus étendues, les deux fenêtres n'étant pas utilisées simultanément, l'évacuation des poils arrachés hors de la zone d'épilation est toujours assurée. Sinon, une zone d'ouverture des pinces spécifiquement dédiée à l'évacuation des poils est prévue.With a device provided with a first epilation window for hair removal restricted areas of the skin and a second window intended for epilating larger areas, the two windows not being used simultaneously, the removal of hairs removed from the hair removal zone is always ensured. Otherwise, an opening area of the pliers specifically dedicated to the evacuation hair is provided.

    • Comme on peut le voir en figure 1 une tête d'épilation d'un appareil selon l'invention est composée de plusieurs modules 100 ayant une forme globale de prisme droit. Les modules portant les pinces d'arrachage sont articulés entre eux côte à côte et forment une chaíne qui circule entre deux flasques 40, 41. La surface enveloppe de la chaíne est alors un prisme droit à section de préférence oblongue présentant des rayons de courbure variables.As can be seen in Figure 1 a hair removal head of a device according to the invention is composed of several modules 100 having a global shape of right prism. The modules carrying the pliers of tearing are articulated between them side by side and form a chain which circulates between two flanges 40, 41. The envelope surface of the chain is then a right prism section preferably oblong with variable radii of curvature.

    Dans une première réalisation de l'invention représentée en figures 3 et 4, l'appareil comporte un boítier 1 comprenant un moteur 2 entraínant la tête d'épilation via un jeu de pignons 3. Une structure interne 4 au boítier 1 supporte le moteur 2, les pignons 3 et deux flasques 40,41 entre lesquels la partie mobile de la tête d'épilation se déplace.In a first embodiment of the invention shown in FIGS. 3 and 4, the apparatus comprises a housing 1 comprising a motor 2 driving the head depilation via a set of gears 3. An internal structure 4 to the housing 1 supports the motor 2, the pinions 3 and two flanges 40, 41 between which the moving part the hair removal head is moving.

    La tête d'épilation comporte un arbre d'entraínement d'axe 5 comportant une roue dentée 6 à chaque extrémité, et plusieurs modules tels que 100 montés côte à côte suivant des génératrices parallèles à l'axe 5 et reliés entre eux par des articulations d'axe 102 pour former une chaíne. Chaque module comporte des éléments d'engrenage 103 susceptibles de venir en liaison avec chaque roue dentée 6, de sorte que la chaíne est entraínée extérieurement par les roues dentées 6. Les flasques 40,41 comportent chacun une rainure 402 dans laquelle circulent les extrémités des axes d'articulation 102 ce qui assure le guidage de la chaíne.The depilating head comprises a drive shaft 5 having a shaft toothed wheel 6 at each end, and several modules such as 100 mounted side by side generatrices parallel to the axis 5 and interconnected by articulations of axis 102 to form a chain. Each module comprises gear elements 103 that can come into contact with each wheel toothed 6, so that the chain is driven externally by the wheels 6. The flanges 40, 41 each comprise a groove 402 in which circulate the ends of the hinge pins 102 which ensures the guiding of the chain.

    Dans une version différente la chaíne est entraínée intérieurement, par exemple en disposant les éléments d'engrenage 103 des modules 100 orientés vers l'intérieur afin de venir en liaison avec au moins une roue d'entraínement située à l'intérieur de la chaíne, roue d'entraínement qui reçoit le mouvement du moteur 2 via un jeu de pignons. Dans une variante avantageuse, la roue d'entraínement est une roue dentée située à l'intérieur de la chaíne, notamment au centre de la face active, ce qui permet de réduire les efforts ainsi que les frottements dans les mécanismes de la chaíne. Dans une autre variante, deux roues d'entraínement sont placées avec leurs axes de rotation aux centres de courbure de la chaíne.In a different version the chain is internally driven, for example by arranging the gear elements 103 of the modules 100 oriented towards interior in order to come into contact with at least one drive wheel located at inside the chain, drive wheel that receives the movement of the motor 2 via a set of gears. In an advantageous variant, the drive wheel is a gear wheel located inside the chain, especially in the center of the active side, which reduces the forces and friction in the mechanisms of the chain. In another variant, two drive wheels are placed with their axes of rotation at the centers of curvature of the chain.

    Chaque module comporte un corps tel que 101 portant une série de lames fixes 110 associées à une série de lames mobiles 111 pour former une série de pinces à épiler. Les lames mobiles sont portées par une coulisse 104 qui est rappelée par un ressort 105 de sorte que les pinces formées par les lames 110,111 soient normalement fermées. La coulisse 104 est reliée rigidement à un poussoir 106 dirigé vers un flasque.Each module has a body such as 101 carrying a series of fixed blades 110 associated with a series of movable blades 111 to form a series of pliers to depilate. The movable blades are carried by a slide 104 which is recalled by a spring 105 so that the tongs formed by the blades 110, 111 are normally closed. The slide 104 is connected rigidly to a pusher 106 directed to a flask.

    Les lames mobiles sont encastrées par exemple par surmoulage sur la coulisse 104. Dans une version différente les lames sont articulées à leur pied sur le corps 101 et la coulisse les entraíne dans un mouvement oscillant pour écarter les lèvres extemes des pincesThe movable blades are embedded for example by overmolding on the slide 104. In a different version the blades are articulated to their foot on the body 101 and the slide drives them in a swinging motion to ward off the outer lips of the tongs

    Dans une version voisine la coulisse ne comporte qu'une seule lame mobile.In a similar version the slide has only one moving blade.

    Avantageusement la première lame 112 de chaque module est positionnée à une distance 113 différente depuis l'extrémité 114 de la partie mobile de la tête à épiler. De préférence les lames des différentes séries sont écartées suivant le même pas 115. Cette distance 113 est choisie pour que les différentes séries de lames balaient des zones de pincement de largeur 116 à des emplacements différents et complémentaires sur la peau.Advantageously, the first blade 112 of each module is positioned at a different distance 113 from the end 114 of the moving part of the head to tweezers. Preferably the blades of the different series are spread according to the not even 115. This distance 113 is chosen so that the different series of blades sweep pinch areas of width 116 at locations different and complementary on the skin.

    Un flasque 40 porte une came 400 dont la face active lui est sensiblement parallèle mais munie de protubérances 401. Chaque protubérance correspond à une zone où les pinces doivent être ouvertes. Les extrémités des poussoirs 106 circulent à proximité immédiate de la came 400, de sorte qu'ils soient actionnés par la ou les protubérances 401.A flange 40 carries a cam 400 whose active face is substantially parallel but provided with protuberances 401. Each protuberance corresponds to an area where the clamps must be open. The tips of the pushers 106 circulate in the immediate vicinity of the cam 400, so that they are actuated by the projection or protuberances 401.

    Dans une version voisine les deux flasques sont munis d'une came et les modules sont montés alternativement de façon à ce que les poussoirs soient concernés par l'une ou l'autre des cames. In a similar version the two flanges are provided with a cam and the modules are mounted alternately so that the pushers are affected by one or other of the cams.

    Dans une autre version dérivée de la précédente, les deux flasques sont munis chacun d'une came et chaque module comporte deux coulisses liées chacune à un poussoir. Les poussoirs de chaque module sont concernés respectivement par les cames des deux flasques. Dans cette version un module comporte deux séries de une ou plusieurs pinces. Le module présente alors une symétrie par rapport à un plan médian de la tête d'épilation.In another version derived from the previous one, the two flanges are provided with each of a cam and each module has two scenes each linked to a pusher. The pushers of each module are respectively concerned by the cams of the two flanges. In this version a module has two series of one or more clamps. The module then presents a symmetry by ratio to a median plane of the hair removal head.

    Lorsque l'utilisatrice met l'appareil en marche, les pignons 6 sont en rotation, entraínant les modules 100 le long de la came 400. Les lames mobiles 111 sont normalement en contact serré contre les lames fixes 110, étant rappelées par le ressort 105. L'extrémité du poussoir 106 est libre mais suit de près la surface de la came 400.When the user turns on the device, the pinions 6 are rotating, driving the modules 100 along the cam 400. The movable blades 111 are normally in close contact against the fixed blades 110, being recalled by the spring 105. The end of the pusher 106 is free but closely follows the surface of the cam 400.

    Lorsqu'un module arrive dans la fenêtre d'épilation, la protubérance 401 de la came 400 agit sur le poussoir 106 qui déplace alors la coulisse 104 contre l'action du ressort 105 entraínant les lames 111 dans un mouvement d'ouverture des pinces d'amplitude 116. Les pilosités peuvent alors s'introduire entre les lames 110,111. Lorsque l'extrémité du poussoir 106 échappe à l'action de la protubérance 401, les pinces formées par les lames 110, 111 se referment en enserrant les poils, sous l'action du ressort 105. Le mouvement d'entraínement de la tête d'épilation arrache alors les poils.When a module arrives in the epilation window, the protuberance 401 of the cam 400 acts on the pusher 106 which then moves the slide 104 against the action of the spring 105 causing the blades 111 in an opening movement 116. The pilosities can then be introduced between the blades 110,111. When the end of the pusher 106 escapes the action of the protrusion 401, the clamps formed by the blades 110, 111 are closed in encircling the hairs, under the action of the spring 105. The movement of training the hair removal head then pulls out the hair.

    Lorsque les pinces sont fermées, il existe un jeu entre l'extrémité du poussoir 106 et la came 400. Le ressort 105 peut alors pleinement exercer son effort sur les poils serrés entre les lames. Le frottement du poussoir 106 sur la came 400 se réduit à un frottement sur la protubérance 401. Avantageusement le frottement est réduit par l'adjonction d'un galet 107 en bout du poussoir 106.When the clamps are closed, there is a clearance between the end of the pusher 106 and the cam 400. The spring 105 can then fully exert its effort on the tight hairs between the blades. The friction of the pusher 106 on the cam 400 is reduced to a friction on the protrusion 401. Advantageously the friction is reduced by the addition of a roller 107 at the end of the pusher 106.

    Dans une deuxième réalisation de l'invention représentée en figure 5, l'appareil diffère de la réalisation précédente par la conception des modules et des cames.In a second embodiment of the invention shown in FIG. differs from the previous embodiment in the design of modules and cams.

    Chaque module comporte un corps 101 portant une série de lames fixes 110 associées à une série de lames mobiles 111 pour former une série de pinces à épiler. Les lames mobiles sont portées par une coulisse 104 qui est rappelée par un ressort 105 de sorte que les pinces formées par les lames 110, 111 soient normalement fermées. Chaque corps de module 101 supporte un axe 117 autour duquel oscille un levier 118. Ce levier est lié à la coulisse 104 par un engrenage. Each module comprises a body 101 carrying a series of fixed blades 110 associated with a series of movable blades 111 to form a series of pliers to tweezers. The movable blades are carried by a slide 104 which is recalled by a spring 105 so that the clamps formed by the blades 110, 111 are normally closed. Each module body 101 supports an axis 117 around which oscillates a lever 118. This lever is connected to the slide 104 by a gear.

    L'extrémité libre 119 du levier 118 est orientée pour que son mouvement d'oscillation soit sensiblement perpendiculaire au mouvement de la coulisse 104 et donc des lames mobiles 111.The free end 119 of the lever 118 is oriented so that its movement oscillation is substantially perpendicular to the movement of the slide 104 and therefore moving blades 111.

    Les lames mobiles sont encastrées par exemple par surmoulage sur la coulisse 104. Dans une version différente les lames sont articulées à leur pied sur le corps 101 et la coulisse les entraíne dans un mouvement oscillant pour écarter les lèvres externes des pincesThe movable blades are embedded for example by overmolding on the slide 104. In a different version the blades are articulated to their foot on the body 101 and the slide drives them in a swinging motion to ward off the outer lips of the tongs

    Dans une version voisine la coulisse ne comporte qu'une seule lame mobile.In a similar version the slide has only one moving blade.

    Avantageusement la première lame 112 de chaque module est positionnée à une distance 113 différente depuis l'extrémité 114 de la partie mobile de la tête à épiler. De préférence les lames des différentes séries sont écartées suivant le même pas 115. Cette distance 113 est choisie pour que les différentes séries de lames balaient des zones de pincement de largeur 116 à des emplacements différents et complémentaires sur la peau.Advantageously, the first blade 112 of each module is positioned at a different distance 113 from the end 114 of the moving part of the head to tweezers. Preferably the blades of the different series are spread according to the not even 115. This distance 113 is chosen so that the different series of blades sweep pinch areas of width 116 at locations different and complementary on the skin.

    Un flasque 40 porte une came 400 dont la face active munie de protubérances lui est sensiblement perpendiculaire. Chaque protubérance correspond à une zone où les pinces doivent être ouvertes. Les extrémités 119 des leviers 118 circulent à proximité immédiate du pourtour de la came 400, de sorte qu'ils soient actionnés par la ou les protubérances.A flange 40 carries a cam 400 whose active face provided with protuberances is substantially perpendicular. Each protuberance corresponds to a zone where the tongs must be open. The ends 119 of the levers 118 circulate in the immediate vicinity of the periphery of the cam 400, so that they are actuated by the one or more protuberances.

    Dans une version voisine les deux flasques sont munis d'une came et les modules sont montés alternativement de façon à ce que les leviers soient concernés par l'une ou l'autre des cames.In a similar version the two flanges are provided with a cam and the modules are mounted alternately so that the levers are affected by one or other of the cams.

    Dans une autre version dérivée de la précédente, les deux flasques sont munis chacun d'une came et chaque module comporte deux coulisses liées chacune à un levier. Les leviers de chaque module sont concernés respectivement par les cames des deux flasques. Dans cette version un module comporte deux séries de une ou plusieurs pinces. Le module présente alors une symétrie par rapport à un plan médian de la tête d'épilation.In another version derived from the previous one, the two flanges are provided with each of a cam and each module has two scenes each linked to a lever. The levers of each module are respectively concerned by the cams of both flanges. In this version a module has two series one or more clamps. The module then has a symmetry with respect to a median plane of the hair removal head.

    Lorsque l'utilisatrice met l'appareil en marche, l'arbre d'axe 5 est en rotation, entraínant les modules le long de la came 400. Les lames mobiles 111 sont normalement en contact serré contre les lames fixes 110, étant rappelées par le ressort 105. L'extrémité 119 du levier 118 est libre mais suit de près la surface de la came 400.When the user turns on the device, the axis shaft 5 is rotated, driving the modules along the cam 400. The movable blades 111 are normally in close contact against the fixed blades 110, being recalled by the spring 105. The end 119 of the lever 118 is free but closely follows the surface of the cam 400.

    Lorsqu'un module arrive dans la fenêtre d'épilation, la protubérance de la came 400 agit sur le levier 118 en le faisant pivoter autour de l'axe 117. Le levier 118 déplace alors la coulisse 104 contre l'action du ressort 105 entraínant les lames 111 dans un mouvement d'ouverture des pinces, de course 116. Les pilosités peuvent alors s'introduire entre les lames 110, 111. Lorsque l'extrémité 119 du levier 118 échappe à l'action de la came 400, les pinces formées par les lames 110, 111 se referment en enserrant les poils, sous l'action du ressort 105. Le mouvement d'entraínement de la tête d'épilation arrache alors les poils.When a module arrives in the epilation window, the protuberance of the cam 400 acts on the lever 118 by pivoting it about the axis 117. The lever 118 then moves the slide 104 against the action of the spring 105 causing the blades 111 in an opening movement of the pliers, race 116. The pilosities can then be introduced between the blades 110, 111. When the end 119 of the lever 118 escapes the action of the cam 400, the clamps formed by the blades 110, 111 are closed by gripping the hairs, under the action of the spring 105. The movement of the hair removal head then pulls the hair.

    Dans ces déplacements, le levier 118 transforme le mouvement des lames 111 et de la coulisse 104 en un mouvement perpendiculaire de l'extrémité 119 en contact avec la came 400. L'axe 117 étant fixé dans le module, aucun effort dans le sens du déplacement des lames n'est transmis à la came ni à la structure de l'appareil. Les efforts perpendiculaires à la surface de la came 400 et sensiblement parallèles au flasque 40 sont équilibrés essentiellement par les axes 102 au travers du flasque 40 qui est donc la seule pièce principalement sollicitée pour commander les lames.In these displacements, the lever 118 transforms the movement of the blades 111 and the slide 104 in a perpendicular movement of the end 119 in contact with the cam 400. The axis 117 being fixed in the module, no effort in the direction of displacement of the blades is not transmitted to the cam nor to the structure of the device. The forces perpendicular to the surface of the cam 400 and substantially parallel to the flange 40 are balanced essentially by the axes 102 through the flange 40 which is therefore the only part mainly solicited to order the blades.

    Par ailleurs le levier 118 permet d'amplifier le mouvement de déplacement des lames et d'en diminuer les efforts sur la came 40. Afin d'assurer une bonne fermeture des pinces, il existe un jeu entre l'extrémité 119 du levier 118 et la came 400 pendant cette fermeture. Le ressort 105 peut alors pleinement exercer son effort sur les poils serrés entre les lames. Le frottement du levier 118 sur la came 400 se réduit à un frottement sur la ou les protubérances.Furthermore, the lever 118 makes it possible to amplify the movement of movement of the blades and to reduce the forces on the cam 40. In order to ensure a good closure of the clamps, there is a clearance between the end 119 of the lever 118 and the cam 400 during this closure. Spring 105 can then fully exercise his effort on the hairs tight between the blades. The friction of the lever 118 on the Cam 400 is reduced to a friction on the protrusion or protrusions.

    La réduction du frottement, des efforts, la maítrise de leur direction et le peu de sollicitation de la structure de l'appareil font de ce dernier un outil fiable et efficace.The reduction of the friction, the efforts, the control of their direction and the little of solicitation of the structure of the device make the latter a reliable tool and effective.

    Dans une troisième réalisation préférentielle représentée en figures 6, 7 et 8, l'appareil diffère de la deuxième réalisation de l'invention par la conception des modules et des cames.In a third preferred embodiment represented in FIGS. 6, 7 and 8, the apparatus differs from the second embodiment of the invention in the design of the modules and cams.

    Chaque module comporte un corps 101 portant deux lames fixes 110 associées respectivement à deux lames mobiles 111 pour former deux pinces à épiler. Chaque lame mobile est portée par un levier 118 rappelé par un ressort 105 de sorte que les pinces formées par les lames 110, 111 soient normalement fermées. Chaque levier 118 oscille autour d'un axe 117 supporté par le corps de module 101. L'extrémité libre 119 du levier 118 est orientée par rapport à l'axe 117 pour que son mouvement d'oscillation soit sensiblement perpendiculaire au mouvement de la lèvre externe de la lame mobile associée 111.Each module comprises a body 101 carrying two associated fixed blades 110 respectively to two movable blades 111 to form two tweezers. Each movable blade is carried by a lever 118 which is biased by a spring 105 of so that the clamps formed by the blades 110, 111 are normally closed. Each lever 118 oscillates about an axis 117 supported by the body of module 101. The free end 119 of the lever 118 is oriented relative to the axis 117 so that its oscillation movement is substantially perpendicular to the movement of the outer lip of the associated movable blade 111.

    Chaque lame mobile est encastrée par exemple par surmoulage sur son levier 118 avec lequel elle forme un sous ensemble monobloc.Each movable blade is embedded for example by overmoulding on its lever 118 with which it forms a monobloc subassembly.

    Avantageusement la première lame du module est positionnée à une distance 113 différente sur chaque module 100 depuis l'extrémité 114 de la partie mobile de la tête à épiler. Cette distance 113 est choisie pour que les pinces des différents modules 100 balaient des zones de largeur 116 à des emplacements différents et complémentaires sur la peau.Advantageously, the first blade of the module is positioned at a distance 113 different on each module 100 from the end 114 of the moving part of the depilatory head. This distance 113 is chosen so that the clips of the different modules 100 scan areas of width 116 at locations different and complementary on the skin.

    Les flasques 40, 41 portent chacun une came 400 dont la face active perpendiculaire aux flasques est munie d'au moins une protubérance 401. Chaque protubérance correspond à une zone où les pinces doivent être ouvertes. Les extrémités 119 des leviers 118 circulent à proximité immédiate du pourtour de la came 400 la plus proche de la lame mobile correspondante, de façon à être actionnées par les protubérances 401.The flanges 40, 41 each carry a cam 400 whose active face perpendicular to the flanges is provided with at least one protuberance 401. Each protuberance corresponds to an area where the clamps must be open. The ends 119 of the levers 118 move in the immediate vicinity of the around the cam 400 closest to the corresponding moving blade, to be actuated by the protuberances 401.

    Dans une version, les cames 400 sont d'épaisseur suffisante pour qu'elles se rejoignent au plan médian de l'appareil, servant ainsi d'entretoise aux deux flasques.In one version, the cams 400 are of sufficient thickness to join to the median plane of the device, thus serving as a spacer for both flanges.

    Le boítier 1 comporte au voisinage de la tête d'épilation deux ouvertures 200 et 300 par où la tête d'épilation peut être appliquée sur la peau à épiler et matérialisant des fenêtres d'épilation. Une ouverture 200 est telle qu'elle permet d'appliquer une zone de forte courbure de la chaíne sur la peau. Cette ouverture comporte une seule zone de pincement due à une des protubérances 401 de la came 400. Une ouverture 300 est telle qu'elle permet d'appliquer une zone de faible courbure de la chaíne sur la peau. Cette ouverture comporte deux zones de pincement dues à deux protubérances 401 de la came 400. The housing 1 has in the vicinity of the epilation head two openings 200 and 300 by which the hair removal head can be applied on the skin to be depilated and materializing hair removal windows. An opening 200 is such that it allows to apply a zone of strong curvature of the chain on the skin. This opening has a single pinch zone due to one of the protuberances 401 of the cam 400. An opening 300 is such that it makes it possible to apply a zone of low curvature of the chain on the skin. This opening has two zones pinching due to two protuberances 401 of the cam 400.

    Lorsque l'utilisatrice met l'appareil en marche, l'arbre d'axe 5 est en rotation, entraínant les modules 100 le long de la came 400. Les lames mobiles 111 sont normalement en contact serré contre les lames fixes 110, étant rappelées par les ressorts 105. Les extrémités 119 des leviers 118 sont libres mais suivent de près la surface des cames 400.When the user turns on the device, the axis shaft 5 is rotated, driving the modules 100 along the cam 400. The movable blades 111 are normally in close contact against the fixed blades 110, being recalled by the springs 105. The ends 119 of the levers 118 are free but follow closely the surface of the cams 400.

    Lorsqu'un module arrive dans la fenêtre d'épilation, la protubérance 401 de la came 400 agit sur le levier 118 en le faisant pivoter autour de l'axe 117. Le levier 118 se déplace alors en pivotant contre l'action du ressort 105 et entraíne la lame 111 dans un mouvement d'ouverture de la pince. Les pilosités peuvent alors s'introduire entre les lames 110, 111. Lorsque l'extrémité 119 du levier 118 échappe à l'action de la protubérance 401, les pinces formées par les lames 110, 111 se referment en enserrant les poils, sous l'action du ressort 105. Le mouvement d'entraínement de la tête d'épilation arrache alors les poils.When a module arrives in the epilation window, the protuberance 401 of the cam 400 acts on the lever 118 by pivoting it about the axis 117. The lever 118 then moves by pivoting against the action of the spring 105 and causes the blade 111 in an opening movement of the clamp. The pilosities can then to enter between the blades 110, 111. When the end 119 of the lever 118 escapes the action of the protuberance 401, the clamps formed by the blades 110, 111 close by clasping the hair, under the action of the spring 105. The movement of the hair removal head then pulls the hair.

    Dans ces déplacements, le levier 118 transforme le mouvement de la lame 111 en un mouvement perpendiculaire de l'extrémité 119 en contact avec la came 400. L'axe 117 étant fixé dans le module, aucun effort dans le sens du déplacement des lames n'est transmis à la came ni à la structure de l'appareil. On retrouve donc les mêmes avantages qu'avec la réalisation précédente.In these displacements, the lever 118 transforms the movement of the blade 111 in a perpendicular movement of the end 119 in contact with the cam 400. Since axis 117 is fixed in the module, no effort in the direction of the movement of the blades is not transmitted to the cam or the structure of the device. We thus find the same advantages as with the previous realization.

    Le rappel en position de fermeture par un ressort de chaque pince permet de bien maítriser le serrage des poils. L'utilisation d'un moyen d 'actionnement pour ouvrir chaque pince simplifie les pièces et permet des tolérances de fabrication plus aisées à satisfaire, la course d'ouverture des lames n'étant pas critique pour obtenir un bon serrage des pinces. Les faibles efforts mis en jeu permettent un défilement rapide de la chaíne propice à un arrachage des poils instantané et peu douloureux.The return to the closed position by a spring of each clamp makes it possible to well control the tightening of the hairs. The use of an actuating means for open each clamp simplifies parts and allows manufacturing tolerances easier to satisfy, the opening stroke of the blades being not critical for get a good clamping of the clamps. The weak efforts put into play allow a rapid movement of the chain conducive to instant hair removal and not very painful

    L'utilisatrice peut se servir de l'une ou de l'autre des fenêtres d'épilation 200, 300. La fenêtre 200 correspondant à une zone de forte courbure de la chaíne est appropriée à épiler des régions précises et limitées de la peau, tandis que la fenêtre 300 comportant plusieurs zone d'arrachage est appropriée à épiler rapidement des surfaces plus grandes.The user can use one or the other epilation windows 200, 300. The window 200 corresponding to a zone of strong curvature of the chain is suitable for epilating specific and limited areas of the skin, while the window 300 with several tear-off zones is suitable for epilating quickly larger surfaces.

    Quand la fenêtre 200 est utilisée, les poils arrachés sont relâchés loin de la peau lorsque les modules parviennent dans la fenêtre 300 inutilisée où les pinces s'ouvrent à nouveau. Lorsque la fenêtre 300 est utilisée les poils entraínés par l'arrachage sont évacués loin de la peau lorsque les modules parviennent dans la fenêtre 200 inutilisée. L'évacuation des poils arrachés est ainsi toujours correcte.When the window 200 is used, the torn hairs are released away from the skin when the modules arrive in the window 300 unused where the clamps open again. When the window 300 is used the bristles driven by tearing are removed away from the skin when the modules arrive in the window 200 unused. The removal of torn hairs is thus always correct.

    Dans une version plus sophistiquée, la fenêtre inutilisée est coiffée par un réceptacle amovible recevant les poils arrachés en vue de leur évacuation ultérieure.In a more sophisticated version, the unused window is capped by a removable receptacle receiving the hairs removed for evacuation higher.

    Ces descriptions montrent de façon non exhaustive la diversité des réalisations possibles tout en restant dans le cadre de l'invention tel que défini par les revendications.These descriptions show in a non-exhaustive way the diversity of achievements possible while remaining within the scope of the invention as defined by the claims.
