Description

APPAREIL A EPILER A PINCES D'ARRACHAGE HAIR REMOVAL APPARATUS
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 hair-removing appliance with pliers capable of being held in the hand and intended for removing excess hair from the human body.
Ce type d'appareil à épiler comporte généralement 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, pour évacuer les poils arrachés.This type of hair removal device generally comprises tweezers in the form of blades or discs arranged on a rotary roller, the tweezers being brought to close and open periodically so as to clamp the hairs close to the skin to pull them out. by the rotation of the roller and, respectively, to evacuate the torn hairs.
Un tel appareil est décrit dans le document EP 0 403 315 au nom de la demanderesse. Ce document décrit un épileur à pinces d'arrachage portées par un rouleau rotatif entraîné par un moteur électrique. Le tout est contenu dans un boîtier formant moyen de préhension manuelle de l'appareil. Chaque pince est formée par une lame appartenant à une série de lames en association avec un disque fixe appartenant à une série de disques. Chaque lame peut pivoter autour de son pied retenu dans une encoche du moyeu du rouleau. Deux barrettes, coulissant parallèlement à l'axe de rotation du rouleau et associées chacune à une série de lames, comportent des rainures engagées chacune sur le bord d'une ouverture centrale de chaque lame de la même série. Pendant la rotation du rouleau, les barrettes actionnées parallèlement à l'axe du rouleau par une came à encontre d'un ressort de renvoi font pivoter les lames de manière à ce que ces dernières viennent en contact avec les disques fixes. A chaque tour du rouleau on observe deux pincements correspondant à la fermeture des deux séries de pinces.Such an apparatus is described in document EP 0 403 315 in the name of the applicant. This document describes an epilator with pliers carried by a rotary roller driven by an electric motor. The whole is contained in a housing forming a means of manual gripping of the apparatus. Each clamp is formed by a blade belonging to a series of blades in association with a fixed disk belonging to a series of disks. Each blade can pivot around its foot held in a notch in the roller hub. Two bars, sliding parallel to the axis of rotation of the roller and each associated with a series of blades, have grooves each engaged on the edge of a central opening of each blade of the same series. During the rotation of the roller, the bars actuated parallel to the axis of the roller by a cam against a return spring rotate the blades so that the latter come into contact with the fixed disks. At each turn of the roller, two pinches are observed corresponding to the closing of the two sets of pliers.
Le document FR 2 678 822 décrit un autre type d'appareil à épiler comportant un rouleau rotatif formé d'une série de lames extérieures solidaires d'un poussoir extérieur et d'une série de lames intérieures montées en opposition solidaires d'un poussoir intérieur. Les poussoirs parallèles à l'axe de rotation du rouleau sont écartés par un ressort taré de manière à maintenir les lames serrées. Lors de la rotation du rouleau, le poussoir intérieur et le poussoir extérieur prennent temporairement un appui simultané sur des cames portées par les flasques supportant l'axe du rouleau pour comprimer le ressort et provoquer l'ouverture des pinces, ce qui permet l'introduction des poils entre les lames en vue de leur arrachage.Document FR 2 678 822 describes another type of epilating device comprising a rotary roller formed by a series of external blades secured to an external pusher and a series of internal blades mounted in opposition secured to an internal pusher . The pushers parallel to the axis of rotation of the roller are separated by a calibrated spring so as to hold the blades tight. During the rotation of the roller, the internal plunger and the external plunger temporarily take simultaneous support on cams carried by the flanges supporting the axis of the roller to compress the spring and cause the opening of the clamps, which allows the introduction bristles between the blades for their uprooting.
Dans ces deux appareils toutes les pinces d'une rangée sont actionnées simultanément lorsqu'elles passent devant une fenêtre du boîtier ouverte vers la zone à épiler. Ceci implique une puissance importante du moteur actionnant simultanément les séries de pinces, puissance qui, de surcroît, varie beaucoup dans le temps, entre une valeur maximale correspondant à l'actionnement des pinces et une valeur minimale quand ces dernières ne sont plus actionnées. Par conséquent, de tels appareils présentent l'inconvénient de nécessiter un moteur puissant, coûteux et encombrant, moteur dont la durée de vie est réduite à cause de la variation continue de sa puissance entre ces deux valeurs extrêmes.In these two devices all the pliers in a row are actuated simultaneously when they pass in front of a window of the open box towards the area to be depilated. This implies a significant power of the motor simultaneously actuating the series of pliers, a power which, moreover, varies greatly over time, between a maximum value corresponding to the actuation of the pliers and a minimum value when the latter are no longer actuated. Consequently, such devices have the drawback of requiring a powerful, costly and bulky motor, an engine whose lifetime is reduced due to the continuous variation of its power between these two extreme values.
Les efforts mis en jeu correspondent à ceux qui sont nécessaires à la fermeture de toute une série de pinces. Ces efforts ne sont pas équilibrés au sein du rouleau et se transmettent aux flasques et au support de rouleau ou au corps de l'appareil, lequel doit être à la fois résistant et pouvoir supporter élastiquement des variations de course pouvant être dues à l'usure ou à l'encombrement d'une pince.The forces involved correspond to those which are necessary for the closure of a whole series of clamps. These forces are not balanced within the roller and are transmitted to the flanges and to the roller support or to the body of the device, which must be both resistant and able to withstand elastically variations in stroke which may be due to wear. or the size of a clamp.
Un autre inconvénient des appareils de ce type, est dû au fait qu'un tel arrachage engendre une douleur importante pour la personne qui subit l'épilation simultanée de tous les poils présents dans la zone de peau voisine de la fenêtre d'épilation. Ceci est d'autant plus évident pour des personnes ayant une forte sensibilité à l'arrachage des poils et également pour des personnes ayant une forte pilosité.Another drawback of devices of this type is due to the fact that such pulling out causes significant pain for the person who undergoes the simultaneous depilation of all the hairs present in the area of skin near the depilation window. This is all the more obvious for people with a high sensitivity to pulling out hairs and also for people with high hair growth.
Afin de pallier ces inconvénients, quelques solutions ont déjà été présentées dans l'état de la technique. Ainsi, dans le document WO 98/05234 est décrit un appareil à épiler à rouleau rotatif constitué par un empilement de disques parallèles agencés côte à côte et portant des lames de pincement, agencées par paires pour former des pinces décalées angulairement l'une par rapport à l'autre. Chaque pince comporte son propre moyen de commande de fermeture. Les disques sont traversés par des tiges de poussée des lames mobiles, parallèles à l'axe du rouleau. Les lames pivotent autour d'un appui central lorsque la tige de poussée vient en contact avec la surface protubérante d'une came portée par l'un ou l'autre flasque, ce qui autorise deux pinces sur la même génératrice du rouleau. Du fait du décalage angulaire, en fonctionnement, seulement deux pinces sont actives lors du passage devant la fenêtre à épiler.In order to overcome these drawbacks, some solutions have already been presented in the state of the art. Thus, in document WO 98/05234 is described a rotary hair-removing device consisting of a stack of parallel discs arranged side by side and carrying pinching blades, arranged in pairs to form clamps offset angularly with respect to each other. Each clamp has its own closing control means. The disks are traversed by push rods of the movable blades, parallel to the axis of the roller. The blades pivot around a central support when the push rod comes into contact with the protruding surface of a cam carried by one or the other flange, which allows two clamps on the same generator of the roller. Due to the angular offset, in operation, only two pliers are active when passing in front of the window to be depilated.
Un tel appareil présente, certes, un arrachage ponctuel au moment du passage des pinces devant la fenêtre d'épilation, mais au prix d'une construction complexe. Par ailleurs le dispositif induit aussi des efforts axiaux sur les flasques support de rouleau, ce qui induit une structure lourde.Such a device has, of course, a punctual lifting when the forceps pass in front of the depilation window, but at the cost of a complex construction. Furthermore, the device also induces axial forces on the roller support flanges, which induces a heavy structure.
Un autre appareil du même type est présenté dans le document EP 0 558 438, appareil à épiler dont la tête d'épilation est munie des paires de pinces qui traversent périodiquement une ouverture du boîtier lorsque ladite tête est entraînée en rotation par un moteur électrique. La tête d'épilation comporte six pinces circulaires, chacune ayant plusieurs bras radiaux, disposées côte à côte de manière à former trois paires de mâchoires agencées décalées sur la circonférence de la tête d'épilation. Chaque pince comporte des protubérances qui viennent en contact avec des cames situées sur les parois internes du boîtier. Les mâchoires pivotent autour de leur point de fixation au centre de la tête en se fermant et s'ouvrant périodiquement de manière à ce qu'une seule pince soit fermée lors du passage devant la fenêtre du boîtier.Another appliance of the same type is presented in document EP 0 558 438, a hair removal appliance the epilation head of which is provided with pairs of pliers which periodically pass through an opening in the housing when said head is rotated by an electric motor. The epilation head comprises six circular pliers, each having several radial arms, arranged side by side so as to form three pairs of jaws arranged offset on the circumference of the epilation head. Each clamp has protrusions which come into contact with cams located on the internal walls of the housing. The jaws pivot around their fixing point in the center of the head, closing and opening periodically so that only one clamp is closed when passing in front of the window of the housing.
L'efficacité de cet appareil est assez limitée vu le frottement des cames sur le pourtour d'une grande roue portant les pinces et que la largeur de la fenêtre d'épilation est très réduite. Les cames induisent aussi des efforts axiaux de serrage qui se répercutent dans le boîtier. De surcroît, un tel appareil fait usage de lames de pincement de forme complexe et donc difficiles à industrialiser pour un coût de fabrication raisonnable. Le document JP - 4005908 décrit une tête d'épilation comportant des disques fixes montés équidistants sur un axe rotatif, deux disques adjacents étant maintenus écartés par des manchons montés sur l'axe rotatif. Des lamelles mobiles sont montées sur lesdits manchons et sont maintenues en position ouverte par rapport aux disques fixes par des ressorts solidaires de la face interne des lames mobiles. Chaque lame mobile forme une pince d'épilation avec le disque voisin, chaque pince étant fermée par une tige poussoir parallèle à l'axe du rouleau et qui lui est propre, traversant le disque fixe. La tige prend appui sur la protubérance axiale d'une came portée par l'un des flasques support du rouleau.The effectiveness of this device is quite limited given the friction of the cams on the periphery of a large wheel carrying the pliers and that the width of the epilation window is very reduced. The cams also induce axial clamping forces which are reflected in the housing. In addition, such an apparatus makes use of pinch blades of complex shape and therefore difficult to industrialize at a reasonable manufacturing cost. Document JP-4005908 describes a depilation head comprising fixed disks mounted equidistant on a rotary axis, two adjacent disks being kept apart by sleeves mounted on the rotary axis. Slats movable are mounted on said sleeves and are held in the open position relative to the fixed discs by springs integral with the internal face of the movable blades. Each movable blade forms a tweezer with the neighboring disc, each clamp being closed by a push rod parallel to the axis of the roller and which is specific to it, passing through the fixed disc. The rod bears on the axial protuberance of a cam carried by one of the support flanges of the roller.
Les cames induisent là aussi des efforts de serrage perpendiculaires aux flasques qui se répercutent dans le boîtier Dans ce document, comme également dans les deux précédents les tiges d'actionnement des lames traversent tous les autres disques ou pinces, ce qui rend complexes les pièces composant l'appareil, leur actionnement, ainsi que l'assemblage de tous ces composants entre eux.The cams also induce clamping forces perpendicular to the flanges which are reflected in the housing. In this document, as also in the previous two, the blade actuating rods pass through all the other discs or pliers, which makes the component parts complex. the device, their actuation, as well as the assembly of all these components together.
Une solution simplifiée pour ce type d'appareils est décrite dans le document JP - 7313243. Dans ce document, les pinces sont constituées par des tiges de forme cylindrique, fendues radialement et supportées le long de la périphérie d'un cylindre entraîné en rotation. Les tiges sont parallèles à l'axe du cylindre.A simplified solution for this type of apparatus is described in document JP-7313243. In this document, the clamps are constituted by cylindrical rods, split radially and supported along the periphery of a cylinder driven in rotation. The rods are parallel to the axis of the cylinder.
Lors de la rotation du cylindre, les pinces passent successivement devant la fenêtre d'épilation du boîtier, leurs extrémités venant en contact avec des cames supportées par les parois latérales du boîtier. Ceci produit le déplacement axial de leurs extrémités et, par conséquent, la fermeture de la pince.During the rotation of the cylinder, the pliers pass successively in front of the epilation window of the housing, their ends coming into contact with cams supported by the side walls of the housing. This produces the axial displacement of their ends and, consequently, the closing of the clamp.
Les inconvénients d'un tel appareil sont liés principalement à la forme des pinces qui présentent dans ce cas une surface de contact importante avec la peau lors de l'épilation, elles frottent sur la peau, ce qui peut produire des irritations et peuvent engendrer une sensation désagréable ou de douleur sur la peau de l'utilisatrice. De surcroît, ces frottements sur la peau imposent une contrainte supplémentaire au moteur d'actionnement de l'appareil.The drawbacks of such an appliance are mainly linked to the shape of the tweezers which in this case have a large contact surface with the skin during depilation, they rub on the skin, which can produce irritations and can cause unpleasant sensation or pain on the user's skin. In addition, this friction on the skin imposes an additional constraint on the actuating motor of the device.
Dans tous ces types d'appareils les cames portées par les flasques impriment aux pinces un mouvement qui est du même ordre de grandeur que le déplacement des lèvres de ces pinces, voire inférieur donc petit devant la taille des pinces. De ce fait d'une part les efforts de serrage ou de desserrage exercés par les cames sont importants et entraînent fréquemment une usure rapide et une perte d'efficacité, d'autre part les efforts produits axialement par un flasque sont équilibrés par l'autre flasque ou par une butée à l'extrémité opposée du rouleau, ce qui nécessite une structure solide pour relier les flasques ou les cames. Il faut aussi maîtriser parfaitement la précision axiale des composants de la tête d'épilation et la rigidité de la structure.In all these types of apparatus, the cams carried by the flanges impart to the clamps a movement which is of the same order of magnitude as the displacement of the lips of these clamps, or even therefore smaller compared to the size of the clamps. Therefore on the one hand the tightening or loosening efforts the cams are important and frequently lead to rapid wear and loss of efficiency, on the other hand the forces produced axially by one flange are balanced by the other flange or by a stop at the opposite end of the roller, this which requires a solid structure to connect the flanges or cams. It is also necessary to perfectly master the axial precision of the components of the epilation head and the rigidity of the structure.
Par ailleurs le brevet US5254124 décrit un épileur dont les pinces sont formées par des mâchoires qui s'appliquent sur le bord intérieur d'un cylindre creux sous l'action d'un ressort. L'extrémité du cylindre est appliquée sur la peau à épiler. Chaque pince est équipée d'un levier d'actionnement qui lui est propre. Les efforts d'une came sur le levier permettent l'ouverture cyclique des pinces pour que les poils s'introduisent. Cet effort est dirigé vers l'axe de rotation de sorte que le cylindre est mécaniquement équilibré et ne transmet aucun effort à la structure de l'appareil. Mais le cylindre creux gêne l'introduction des poils dans les pinces peu nombreuses et les pinces restant en permanence en contact avec la peau, l'évacuation des poils arrachés enfermés dans un cylindre est difficile. Aussi l'efficacité de cet appareil est elle limitée par rapport à ceux où les pinces sont placées sur les génératrices externes de la tête d'épilation. Le but de la présente invention est de remédier aux inconvénients susmentionnés et de proposer un appareil à épiler comportant des pinces d'arrachage formées de lames mobiles en association soit avec d'autres lames mobiles, soit avec des lames fixes, actionnées par des moyens mécaniques de commande entraînés par un moteur électrique, l'appareil ayant une bonne efficacité, une durée de vie améliorée, et une construction permettant des tolérances de fabrication plus grandes.Furthermore, patent US Pat. No. 5,254,124 describes an epilator whose clamps are formed by jaws which are applied to the inner edge of a hollow cylinder under the action of a spring. The end of the cylinder is applied to the skin to be depilated. Each clamp is fitted with its own actuation lever. The efforts of a cam on the lever allow the cyclic opening of the clamps so that the hairs are introduced. This force is directed towards the axis of rotation so that the cylinder is mechanically balanced and does not transmit any force to the structure of the device. However, the hollow cylinder hinders the introduction of the bristles into the pliers which are few and the pliers remaining permanently in contact with the skin, the evacuation of the plucked hairs enclosed in a cylinder is difficult. Also the effectiveness of this device is it limited compared to those where the clamps are placed on the external generators of the epilation head. The object of the present invention is to remedy the aforementioned drawbacks and to propose an epilating device comprising pliers of pliers formed from movable blades in association either with other movable blades or with fixed blades, actuated by mechanical means. control driven by an electric motor, the apparatus having a good efficiency, an improved service life, and a construction allowing larger manufacturing tolerances.
Ces buts sont atteints avec un appareil à épiler comportant un boîtier, un moteur électrique mettant en mouvement une tête d'épilation à pinces d'arrachage, la partie mobile de la tête ayant une surface enveloppe réglée dont les génératrices rectilignes sont perpendiculaires au mouvement, et étant supportée par deux flasques latéraux, chaque pince se déplaçant le long de la surface enveloppe dans un plan perpendiculaire à la zone d'épilation et parallèle aux flasques, 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, du fait que lesdits premiers moyens agissent sur lesdits seconds moyens suivant une direction sensiblement parallèle aux flasques.These goals are achieved with a hair removal device comprising a housing, an electric motor setting in motion a depilation head with pliers, the movable part of the head having a regulated envelope surface whose rectilinear generatrixes are perpendicular to the movement, and being supported by two lateral flanges, each clamp moving along the envelope surface in a plane perpendicular to the epilation zone and parallel to the flanges, each clamp comprising at least one movable blade actuated by mechanical means to obtain the closing or opening of the clamps, said mechanical means comprising in at least one flange of the first control means acting as a cam and on the part movable from the epilation head of the second actuating means receiving the movement due to the cam and transmitting it to the movable blades, due to the fact that said first means act on said second means in a direction substantially parallel to the flanges.
Par surface enveloppe réglée on entend une surface 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.By regulated envelope surface is meant a surface enveloping the epilation head and which is generated by a straight line moving in translation or in rotation or by a combination of the two movements.
Inversement, de façon analogue et évidente et sans sortir du cadre de l'invention, les moyens faisant office de came peuvent être sur la partie mobile de la tête d'épilation et participer au transfert vers les pinces du mouvement, tandis que le flasque peut être muni d'un moyen fixe agissant sur la came suivant une direction essentiellement parallèle aux flasques, le mouvement relatif obtenu étant le même et dans la même direction.Conversely, in a similar and obvious manner and without departing from the scope of the invention, the means acting as a cam can be on the movable part of the epilation head and participate in the transfer to the clamps of the movement, while the flange can be provided with a fixed means acting on the cam in a direction essentially parallel to the flanges, the relative movement obtained being the same and in the same direction.
Alors que les dispositifs efficaces connus sont des rouleaux dont les pinces sont actionnées par des poussoirs agissant sur les flasques et tendent à les écarter, les moyens du dispositif proposé n'engendrent pas de composante des efforts normale aux flasques se répercutant sur la partie mobile de la tête d'épilation. La structure de l'appareil s'en trouve allégée, les courses des pinces ne dépendent plus des jeux entre la partie mobile et les flasques. Les efforts perpendiculaires au mouvement général étant nuls l'usure correspondante est supprimée, et la précision de l'assemblage est moins critique pour un bon fonctionnement.While the known effective devices are rollers, the clamps of which are actuated by pushers acting on the flanges and tend to spread them apart, the means of the proposed device do not generate any component of the forces normal to the flanges which affect the movable part of the epilation head. The structure of the device is reduced, the strokes of the clamps no longer depend on the games between the mobile part and the flanges. Since the forces perpendicular to the general movement are zero, the corresponding wear is eliminated, and the precision of the assembly is less critical for proper operation.
La partie mobile de la tête d'épilation comprend des pinces formées par les bords de deux lames, se déplaçant sur la surface enveloppe, également appelés lèvres, l'une au moins étant mobile par rapport à l'autre. Les pinces sont alignées de façon connue sur la surface enveloppe de la tête d'épilation dont une partie constitue la surface active appliquée sur la peau à épiler. Cette surface enveloppe est classiquement une surface réglée dont les génératrices sont à la fois perpendiculaires au mouvement et aux flasques latéraux. Ci après on appelle lèvres les bords des lames qui serrent les poils et sont tangents à la surface enveloppe de la tête d'épilation.The movable part of the epilation head comprises pliers formed by the edges of two blades, moving on the envelope surface, also called lips, at least one being movable relative to the other. The pliers are aligned in a known manner on the envelope surface of the epilation head, part of which constitutes the active surface applied to the skin to be epilated. This envelope surface is conventionally a regulated surface whose generators are both perpendicular to the movement and to the side plates. Hereinafter, the edges of the blades which clamp the hairs and are tangent to the envelope surface of the epilation head are called lips.
De préférence 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.Preferably the second actuating means comprise a movement reference transforming the initial movement substantially parallel to the flanges due to the first means into a movement of the lips of movable blades 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 forces tending to move the movable part of the epilation head, to separate the flanges and capable of mechanically stressing the structure of the device.
De préférence les moyens de commande sont constitués par une ou des cames solidaires des flasques latéraux de la tête d'épilation, la surface de travail de ces cames étant perpendiculaire aux flasques.Preferably, the control means are constituted by one or more cams integral with the lateral flanges of the epilation head, the working surface of these cams being perpendicular to the flanges.
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 main forces exerted on this surface are parallel to the flanges and do not tend to move them apart.
De préférence le renvoi de mouvement est un levier pivotant autour d'un axePreferably the movement reference is a lever pivoting around 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 movable blade moves parallel to the skin, and the end of the lever moves substantially in a plane parallel to the flanges. The longitudinal clamping forces of the pliers are balanced by the axis of rotation belonging to the movable part of the epilation head. Furthermore, the use of a lever makes it possible to amplify the movement of the clamp and to reduce the forces on the control cam. The movements, being amplified, become large before the manufacturing tolerances of the parts and the games, as well as before 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. 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.Preferably, the device comprises as many actuating means as there are movable blades with which they are respectively associated, these second means being actuated by the same first control means. The movable blades being actuated independently of each other, a crowded clamp does not affect the tightening of the other clamps. The effectiveness is increased. The forces on each actuating means are low, 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. 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.Preferably each movable blade is associated with a lever making with the latter a one-piece sub-assembly pivoting about an axis. Each blade is then mobile in oscillation around the axis. The construction is very simple, robust, and requires only an easily controllable operating clearance. Alternatively, the end of the lever has a roller to 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 soumise à l'action du renvoi de mouvement.In another version, the movable blades, the lips of which are located on the same generatrix of the envelope surface of the epilation head, are associated with at least one slide subjected to the action of movement movement.
La coulisse se déplace perpendiculairement aux flasques et entraîne les lames mobiles dans une oscillation autour du pied de chaque lame ou dans une translation. Le renvoi de mouvement est de préférence un levier qui transforme ce déplacement en un mouvement parallèle aux flasques en agissant par exemple sur un talon ou un engrenage de la coulisse.The slide moves perpendicular to the flanges and drives the movable blades in an oscillation around the foot of each blade or in a translation. The movement reference is preferably a lever which transforms this movement into a movement parallel to the flanges by acting, for example, on a heel or a gear of the slide.
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. Les pinces étant fermées sous l'action d'un ressort, la pression de serrage des poils est constante dans le temps et bien maîtrisée 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.Preferably the pliers are normally closed under the action of an elastic means such as a spring and the mechanical means act to open the pliers. The clamps being closed under the action of a spring, the clamping pressure of the bristles is constant over time and well controlled without adjustments being necessary for assembly or during use. It does not depend on the stroke of the blades or the degree of wear of the mechanical opening means, reliability is increased. The force of closing of the clamps by the spring is determined so as to ensure an optimum tightening making it possible to grip all types of hairs well, without however cutting them during pulling out.
A l'ouverture des pinces les moyens mécaniques agissent à encontre du ressort de serrage dont l'effort est sensiblement constant. Les efforts d'ouverture mis en jeu sont donc parfaitement contrôlés. 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. De préférence les pinces sont décalées 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.When the pliers open, the mechanical means act against the clamping spring, the force of which is substantially constant. The opening efforts involved are therefore perfectly controlled. The springs can be applied directly against the movable clamp or on a part of the actuating means such as the slide or the lever. Preferably the pliers are offset so that from one pliers from one generator to that of the next, the nip areas complement each other 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 nip area of the tweezers which appear successively, a complete sweep of the area to be epilated is obtained.
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 concernée.Preferably, the pliers being distributed over different generators of the movable part of the epilation head, two pliers are arranged on each generator concerned.
Chaque pince a alors son mouvement d'ouverture commandé par la came du flasque le plus proche. Les pinces sont réparties de manière uniforme sur le pourtour de la surface enveloppe de la tête d'épilation, l'effort de serrage est également uniformément réparti dans le temps, d'où une sollicitation moindre du moteur d'entraînement et un moindre coût de son alimentation électrique.Each clamp then has its opening movement controlled by the cam of the nearest flange. The pliers are distributed uniformly around the periphery of the envelope surface of the epilation head, the clamping force is also uniformly distributed over time, resulting in less stress on the drive motor and lower cost of its power supply.
De préférence au moins deux pinces d'arrachage sont fermées simultanément au moment de leur passage dans la zone à épiler.Preferably at least two pliers are closed simultaneously at the time of their passage in the area to be depilated.
De préférence les pinces à épiler situées sur une même génératrice, leurs moyens d'actionnement et leurs moyens élastiques sont montés dans un support commun avec lequel ils forment un ensemble unitaire.Preferably the tweezers located on the same generator, their actuating means and their elastic means are mounted in a common support with which they form a unitary assembly.
Ces ensembles unitaires sont montés à la périphérie de la surface enveloppe de la tête d'épilation. Cette conception modulaire de la tête d'épilation permet la réalisation de nombreuses variantes d'appareils, en changeant le nombre de modules on change le nombre de pinces et on peut faire varier la taille de la tête d'épilation. Un seul outil de fabrication est nécessaire pour obtenir différentes versions. De préférence la tête d'épilation est un rouleau entraîné en rotation autour de son axeThese unitary assemblies are mounted on the periphery of the envelope surface of the epilation head. This modular design of the epilation head allows the realization of many variants of devices, by changing the number of modules we change the number of pliers and we can vary the size of the epilation head. Only one manufacturing tool is required to obtain different versions. Preferably the epilation head is a roller driven in rotation around its axis
La tête d'épilation se présente sous la forme d'un rouleau comportant un moyeu autour duquel sont disposés les ensembles unitaires, le moyeu ayant un axe supporté par les flasques. Dans une autre version la tête d'épilation est composée d'ensembles unitaires montés rigidement côte à côte, le tout étant animé d'un mouvement alternatif déplaçant les pinces sur une surface réglée.The epilation head is in the form of a roller comprising a hub around which the unit assemblies are arranged, the hub having an axis supported by the flanges. In another version the epilation head is made up of unitary sets rigidly mounted side by side, the whole being driven by an alternating movement moving the clamps on a set surface.
La surface réglée peut être plane ou cylindrique. Le mouvement alternatif est parallèle à ladite surface. Dans une autre version, la tête d'épilation est composée d'ensembles unitaires articulés entre eux côte à côte et qui forment une chaîne.The adjusted surface can be flat or cylindrical. The reciprocating movement is parallel to said surface. In another version, the epilation head is made up of unitary sets articulated together side by side and which form a chain.

La figure 7 est une autre vue en perspective de la tête d'épilation de la figure 4.FIG. 7 is another perspective view of the depilation head of FIG. 4.
Dans une première réalisation de l'invention représentée en figure 1 , l'appareil comporte un boîtier 1 comprenant un moteur 2 entraînant la tête d'épilation via un jeu de pignons 3. Une structure interne 4 au boîtier 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 FIG. 1, the device comprises a housing 1 comprising a motor 2 driving the epilation head via a set of pinions 3. An internal structure 4 in the housing 1 supports the motor 2, the pinions 3 and two flanges 40,41 between which the movable part of the epilation head moves.
La partie mobile de la tête d'épilation se compose d'un axe d'entraînement 5 sur lequel est monté un moyeu 6 et des modules tels que 7, montés en périphérie du moyeu 6 suivant des génératrices parallèles à l'axe pour former un rouleau sensiblement cylindrique d'axe 5.The movable part of the epilation head consists of a drive shaft 5 on which is mounted a hub 6 and modules such as 7, mounted on the periphery of the hub 6 along generatrices parallel to the axis to form a substantially cylindrical roller with axis 5.
Chaque module comporte un corps tel que 9 ou 9' portant une série de lames fixes 10 disposées à la périphérie du rouleau et associées à une série de lames mobiles 11 pour former une série de pinces à épiler. Les lames mobiles sont portées par une coulisse 12 qui est rappelée par un ressort 13 de sorte que les pinces formées par les lames 10, 11 soient normalement fermées. Chaque corps de module tel que 9 supporte un axe 14 autour duquel oscille un levier 15. Ce levier est lié à la coulisse 12 par un engrenage. L'extrémité libre 151 du levier 15 est orientée pour que son mouvement d'oscillation soit sensiblement perpendiculaire au mouvement de la coulisse 12 et donc des lames mobiles 11.Each module comprises a body such as 9 or 9 ′ carrying a series of fixed blades 10 arranged at the periphery of the roller and associated with a series of movable blades 11 to form a series of tweezers. The movable blades are carried by a slide 12 which is returned by a spring 13 so that the clamps formed by the blades 10, 11 are normally closed. Each module body such as 9 supports an axis 14 around which a lever 15 oscillates. This lever is linked to the slide 12 by a gear. The free end 151 of the lever 15 is oriented so that its oscillating movement is substantially perpendicular to the movement of the slide 12 and therefore of the movable blades 11.
Les lames mobiles sont encastrées par exemple par surmoulage sur la coulisse 12. Dans une version différente les lames sont articulées à leur pied sur le corps 9 et la coulisse les entraîne dans un mouvement oscillant pour écarter les lèvres externes des pincesThe movable blades are embedded for example by overmolding on the slide 12. In a different version the blades are articulated at their feet on the body 9 and the slide drives them in an oscillating movement to spread the outer lips of the clamps
Dans une version voisine la coulisse 12 ne comporte qu'une seule lame mobile.In a neighboring version, the slide 12 has only one movable blade.
Avantageusement la première lame 101 de chaque module tel que 7 est positionnée à une distance 17 différente depuis l'extrémité 16 de la partie mobile de la tête à épiler. De préférence les lames des différentes séries sont écartées suivant le même pas 18. Cette distance 17 est choisie pour que les différentes séries de lames balaient des zones de pincement de largeur 19 à des emplacements différents et complémentaires sur la peau.Advantageously, the first blade 101 of each module such as 7 is positioned at a different distance 17 from the end 16 of the movable part of the head to be depilated. Preferably, the blades of the different series are spaced along the same pitch 18. This distance 17 is chosen so that the different series of blades sweep pinch zones of width 19 at different and complementary locations on the skin.
Un flasque 40 porte une came cylindrique 400 munie d'une protubérance radiale 401. La protubérance correspond à une zone où les pinces doivent être ouvertes. Les extrémités des leviers 15 circulent à proximité immédiate du pourtour de la came 400, de sorte qu'ils soient actionnés par la protubérance 401.A flange 40 carries a cylindrical cam 400 provided with a radial protuberance 401. The protuberance corresponds to an area where the clamps must be open. The ends of the levers 15 run in the immediate vicinity of the periphery of the cam 400, so that they are actuated by the protuberance 401.
Dans une version voisine les deux flasques 40, 41 sont munis d'une came telle que 400 et les modules 7 sont montés alternativement de façon à ce que les leviers 15 soient concernés à droite puis à gauche par l'une ou l'autre des cames 400.In a neighboring version, the two flanges 40, 41 are provided with a cam such as 400 and the modules 7 are mounted alternately so that the levers 15 are concerned on the right then on the left by one or the other of the cams 400.
Dans une autre version dérivée de la précédente, les deux flasques 40 et 41 sont munis chacun d'une came 400 et chaque module comporte deux coulisses 12 liées chacune à un levier. Les leviers de chaque module sont concernés respectivement par les cames des flasques 40 et 41. 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 40 and 41 are each provided with a cam 400 and each module comprises two slides 12 each linked to a lever. The levers of each module are affected respectively by the cams of the flanges 40 and 41. In this version, a module comprises two series of one or more clamps. The module then has symmetry with respect to a median plane of the epilation head.
Lorsque l'utilisatrice met l'appareil en marche, l'axe 5 est en rotation, entraînant les modules 7 le long de la came 400. Les lames mobiles 11 sont normalement en contact serré contre les lames fixes 10, étant rappelées par le ressort 13. L'extrémité 151 du levier 15 est libre mais suit de près la surface de la came 400. Lorsqu'un module arrive dans la fenêtre d'épilation, la protubérance 401 de la came 400 agit sur le levier 15 en le faisant pivoter autour de l'axe 14. Le levier 15 déplace alors la coulisse 12 contre l'action du ressort 13 entraînant les lames 11 dans un mouvement d'ouverture des pinces de course 19. Les pilosités peuvent alors s'introduire entre les lames 10,11. Lorsque l'extrémité 151 du levier 15 échappe à l'action de la protubérance 401 , les pinces formées par les lames 10,11 se referment en enserrant les poils, sous l'action du ressort 13. Le mouvement d'entraînement de la tête d'épilation arrache alors les poils.When the user starts the appliance, the axis 5 is in rotation, driving the modules 7 along the cam 400. The movable blades 11 are normally in tight contact against the fixed blades 10, being returned by the spring 13. The end 151 of the lever 15 is free but closely follows the surface of the cam 400. When a module arrives in the depilation window, the protuberance 401 of the cam 400 acts on the lever 15 by making it pivot around the axis 14. The lever 15 then moves the slide 12 against the action of the spring 13 causing the blades 11 in an opening movement of the stroke clamps 19. The pilosities can then be introduced between the blades 10, 11. When the end 151 of the lever 15 escapes the action of the protuberance 401, the clamps formed by the blades 10, 11 are closed by enclosing the bristles, under the action of the spring 13. The drive movement of the head hair removal then plucks the hairs.
Dans ces déplacements, le levier 15 transforme le mouvement des lames 11 et de la coulisse 12 en un mouvement perpendiculaire de l'extrémité 151 en contact avec la came 400. L'axe 14 étant fixé dans le module 7, 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 l'axe 5 au travers du flasque 40 qui est donc la seule pièce principalement sollicitée pour commander les lames.In these movements, the lever 15 transforms the movement of the blades 11 and of the slide 12 into a perpendicular movement of the end 151 in contact with the cam 400. The axis 14 being fixed in the module 7, no effort in the direction of the movement of the blades is not transmitted to the cam or 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 axis 5 through the flange 40 which is therefore the only part mainly used to control the blades.
Par ailleurs le levier 15 permet d'amplifier le mouvement de déplacement des lames et d'en diminuer les efforts sur la came 400. Afin d'assurer une bonne fermeture des pinces, il existe un jeu entre l'extrémité 151 du levier 15 et la came 400 pendant cette fermeture. Le ressort 13 peut alors pleinement exercer son effort sur les poils serrés entre les lames. Le frottement du levier 15 sur la came 400 se réduit à un frottement sur la protubérance 401.Furthermore, the lever 15 makes it possible to amplify the movement of movement of the blades and to reduce the forces thereof on the cam 400. In order to ensure that the clamps are properly closed, there is play between the end 151 of the lever 15 and the cam 400 during this closing. The spring 13 can then fully exert its force on the bristles clamped between the blades. The friction of the lever 15 on the cam 400 is reduced to friction on the protuberance 401.
La réduction du frottement, des efforts, la maîtrise de leur direction et le peu de sollicitation de la structure de l'appareil font de ce dernier un outil fiable et efficace.Reduction of friction, efforts, control of their direction and little stress on the structure of the device make it a reliable and efficient tool.
Dans une deuxième réalisation préférentielle représentée en figure 2, l'appareil comporte comme dans la réalisation précédente un boîtier 1 , un moteur 2, un jeu de pignons 3, une structure interne 4 et deux flasques 40,41 entre lesquels la partie mobile de la tête d'épilation se déplace.In a second preferred embodiment shown in FIG. 2, the device comprises, as in the previous embodiment, a housing 1, a motor 2, a set of pinions 3, an internal structure 4 and two flanges 40, 41 between which the movable part of the hair removal head moves.
La partie mobile de la tête d'épilation également représentée en figure 3 se compose d'un axe d'entraînement 5 sur lequel est monté un moyeu 6 et des modules tels que 7, montés en périphérie du moyeu 6 suivant des génératrices parallèles à l'axe pour former un rouleau sensiblement cylindrique d'axe 5.The mobile part of the epilation head also shown in Figure 3 consists of a drive shaft 5 on which is mounted a hub 6 and modules such as 7, mounted on the periphery of the hub 6 along generatrices parallel to the axis to form a substantially cylindrical roller with axis 5.
Chaque module comporte un corps tel que 9 portant deux lames fixes 10 disposées à la périphérie du rouleau et associées respectivement à deux lames mobiles 11 pour former deux pinces à épiler. Chaque lame mobile est portée par un levier 15 rappelé par un ressort 13 de sorte que les pinces formées par les lames 10, 11 soient normalement fermées. Chaque levier 15 oscille autour d'un axe 14 supporté par le corps de module tel que 9. L'extrémité libre 151 du levier 15 est orientée par rapport à l'axe 14 pour que son mouvement d'oscillation soit sensiblement perpendiculaire au mouvement de la lèvre externe de la lame mobile 11. Chaque lame mobile est encastrée par exemple par surmoulage sur son levier 15 avec lequel elle forme un sous ensemble monobloc.Each module comprises a body such as 9 carrying two fixed blades 10 disposed at the periphery of the roller and associated respectively with two movable blades 11 to form two tweezers. Each movable blade is carried by a lever 15 returned by a spring 13 so that the clamps formed by the blades 10, 11 are normally closed. Each lever 15 oscillates around an axis 14 supported by the module body such as 9. The free end 151 of the lever 15 is oriented relative to the axis 14 so that its oscillation movement is substantially perpendicular to the movement of the outer lip of the movable blade 11. Each movable blade is embedded for example by overmolding on its lever 15 with which it forms a one-piece sub-assembly.
Avantageusement la première lame 10 est positionnée à une distance 17 différente sur chaque module 7 depuis l'extrémité 16 de la partie mobile de la tête à épiler. Cette distance 17 est choisie pour que les pinces des différents modules 7 balaient des zones de largeurs 19 à des emplacements différents et complémentaires sur la peau.Advantageously, the first blade 10 is positioned at a different distance 17 on each module 7 from the end 16 of the movable part of the head to be depilated. This distance 17 is chosen so that the clamps of the different modules 7 sweep areas of width 19 at different and complementary locations on the skin.
Ainsi, les leviers 15 ont des dimensions différentes en fonction de la distance à laquelle une lame est positionnée par rapport à l'extrémité 16. De manière avantageuse, on peut déterminer un rapport optimal entre les dimensions des leviers et le déphasage angulaire des modules de manière à utiliser un nombre maximum de leviers identiques, ce qui réduit les coûts de fabrication et facilite l'assemblage.Thus, the levers 15 have different dimensions depending on the distance at which a blade is positioned relative to the end 16. Advantageously, it is possible to determine an optimal ratio between the dimensions of the levers and the angular phase shift of the modules of so as to use a maximum number of identical levers, which reduces manufacturing costs and facilitates assembly.
Les flasques 40,41 portent chacun une came cylindrique 400 munie d'une protubérance radiale 401. La protubérance correspond à une zone où les pinces doivent être ouvertes. Les extrémités 151 des leviers 15 circulent à proximité immédiate du pourtour de la came 400 la plus proche de la lame mobile correspondante, de façon à être actionnées par la protubérance 401.The flanges 40, 41 each carry a cylindrical cam 400 provided with a radial protuberance 401. The protuberance corresponds to an area where the clamps must be opened. The ends 151 of the levers 15 circulate in the immediate vicinity of the periphery of the cam 400 closest to the corresponding movable blade, so as to be actuated by the protuberance 401.
Lorsque l'utilisatrice met l'appareil en marche, l'axe 5 est en rotation, entraînant les modules 7 le long de la came 400. Les lames mobiles 11 sont normalement en contact serré contre les lames fixes 10, étant rappelées par les ressorts 13, comme illustré en partie inférieure de la tête d'épilation de la figure 2. Les extrémités 151 des leviers 15 sont libres mais suivent de près la surface des cames 400.When the user starts the device, the axis 5 is in rotation, driving the modules 7 along the cam 400. The movable blades 11 are normally in tight contact against the fixed blades 10, being returned by the springs 13, as illustrated in the lower part of the depilation head of FIG. 2. The ends 151 of the levers 15 are free but closely follow 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 15 en le faisant pivoter autour de l'axe 14 comme illustré en partie supérieure de la tête d'épilation de la figure 2. Le levier 15 se déplace alors en pivotant contre l'action du ressort 13 et entraîne les lames 11 dans un mouvement d'ouverture des pinces de course 19. Les pilosités peuvent alors s'introduire entre les lames 10,11. Lorsque l'extrémité 151 du levier 15 échappe à l'action de la protubérance 401 , les pinces formées par les lames 10,11 se referment en enserrant les poils, sous l'action du ressort 13. Le mouvement d'entraînement 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 15 by making it pivot around the axis 14 as illustrated in the upper part of the epilation head of FIG. 2. The lever 15 then moves by pivoting against the action of the spring 13 and drives the blades 11 in an opening movement of the stroke clamps 19. The pilosities can then be introduced between the blades 10,11. When the end 151 of the lever 15 escapes the action of the protuberance 401, the clamps formed by the blades 10, 11 are closed by enclosing the bristles, under the action of the spring 13. The drive movement of the head hair removal then plucks the hairs.
Dans ces déplacements, le levier 15 transforme le mouvement des lames 11 en un mouvement perpendiculaire de l'extrémité 151 en contact avec la came 400. L'axe 14 étant fixé dans le module 7, 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 movements, the lever 15 transforms the movement of the blades 11 into a perpendicular movement of the end 151 in contact with the cam 400. The axis 14 being fixed in the module 7, no effort in the direction of movement of the blades n 'is transmitted to the cam or to the structure of the device. We therefore find the same advantages as with the previous embodiment.
Le rappel en position de fermeture par un ressort de chaque pince permet de bien maîtriser 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. Dans une troisième réalisation de l'invention, des modules 7 semblables à ceux de la réalisation précédente sont assemblés côte à côte comme indiqué en figure 4 pour que l'ensemble des lèvres des lames soient sur une même surface active S. L'ensemble est animé par des moyens motorisés non représentés d'un mouvement alternatif suivant la direction des flèches f parallèle à la surface active S destinée à s'appliquer sur la peau. La figure représente une surface active S sensiblement plane animée d'un mouvement rectiligne. Dans une version voisine la surface est cylindrique et animée d'un mouvement alternatif curviligne dans un plan diamétral. La figure 5 montre une vue partielle de l'appareil en coupe par un plan de symétrie d'un module. Le boîtier 1 contient deux flasques 40,41 munis d'une rainure longiligne 20 parallèle au déplacement des modules 7 et assurant leur guidage. Les flasques portent une came 400 sensiblement parallèle à la rainure 20 mais comportant une ou plusieurs protubérances 401 s'étendant parallèlement aux flasques dans les zones où les pinces doivent être ouvertes.The return to the closed position by a spring of each clamp makes it possible to properly control the clamping of the bristles. The use of an actuating means to open each clamp simplifies the parts and allows manufacturing tolerances which are easier to meet, the opening stroke of the blades not being critical for obtaining good clamping of the clamps. In a third embodiment of the invention, modules 7 similar to those of the previous embodiment are assembled side by side as indicated in FIG. 4 so that the assembly of the lips of the blades is on the same active surface S. The assembly is driven by motorized means not shown in an alternating movement in the direction of the arrows f parallel to the active surface S intended to be applied to the skin. The figure represents a substantially planar active surface S animated by a rectilinear movement. In a neighboring version the surface is cylindrical and animated by an alternating curvilinear movement in a diametral plane. Figure 5 shows a partial view of the device in section through a plane of symmetry of a module. The housing 1 contains two flanges 40, 41 provided with an elongate groove 20 parallel to the displacement of the modules 7 and ensuring their guidance. The flanges carry a cam 400 substantially parallel to the groove 20 but comprising one or more protrusions 401 extending parallel to the flanges in the areas where the clamps must be open.
Les cames 400 agissent sur les leviers 15 de la même manière que dans les réalisations précédentes. Les efforts développés par les cames 400 dans des plans parallèles aux flasques sont équilibrés par les efforts exercés par les rainures 20, de sorte que les flasques soient les seules pièces à transmettre les principaux efforts de commande. On obtient des avantages similaires à ceux des réalisations précédentes.The cams 400 act on the levers 15 in the same way as in the previous embodiments. The forces developed by the cams 400 in planes parallel to the flanges are balanced by the forces exerted by the grooves 20, so that the flanges are the only parts to transmit the main control forces. Advantages similar to those of the previous embodiments are obtained.
Dans une quatrième réalisation, les modules sont assemblés en chaîne comme on peut le voir sur les figures 6 et 7. Le mouvement d'entraînement des modules est continu à la façon d'une chenille et le fonctionnement est semblable à celui de la réalisation décrite précédemment.In a fourth embodiment, the modules are assembled in a chain as can be seen in FIGS. 6 and 7. The drive movement of the modules is continuous like a track and the operation is similar to that of the embodiment described previously.
Ces descriptions montrent de façon non exhaustive la diversité des réalisations possibles tout en restant dans le cadre de l'invention. Cette diversité est permise essentiellement par l'allégement des contraintes de commande des lames mobiles. These descriptions non-exhaustively show the diversity of possible embodiments while remaining within the scope of the invention. This diversity is made possible essentially by the reduction in the control constraints of the movable blades.
