Description

APPAREIL A EPILER A ROULEAU ROTATIF VIBRANT HAIR REMOVAL DEVICE WITH ROTARY VIBRATING ROLLER
La présente invention est relative à un appareil à épiler du type comportant un rouleau rotatif muni des pinces destinées à arracher les poils superflus, non désirés, du corps humain.The present invention relates to a hair removal device of the type comprising a rotary roller provided with pliers intended to pluck unwanted, unwanted hair from the human body.
Ce type d'appareil comporte 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 et, respectivement, à évacuer les poils arrachés de par la rotation du rouleau. L'arrachage des poils s'avère une méthode très efficace contre leur repousse, mais, souvent, il engendre une douleur non négligeable.This type of device comprises tongs in the form of blades or discs arranged on a rotary roller, the tongs being brought to close and open periodically so as to clamp the hairs close to the skin and, respectively, to evacuate hairs pulled out by the rotation of the roller. Pulling out hair is a very effective method against regrowth, but often it causes significant pain.
L'état de la technique atteste l'utilisation de plusieurs méthodes faisant appel à différents dispositifs antidouleur associés à des appareils à épiler. Ainsi, on connaît, notamment du document WO 95/07638 au nom de la demanderesse, un dispositif de refroidissement de la peau, juste avant l'épilation, en utilisant l'évaporation d'un liquide déposé sur la peau. Ce dispositif fait cependant appel à des moyens, tels un réservoir de liquide, un ventilateur, qui augmentent l'encombrement et le coût de l'appareil.The state of the art attests to the use of several methods using different painkillers associated with hair removal devices. Thus, there is known, in particular from document WO 95/07638 in the name of the applicant, a device for cooling the skin, just before depilation, by using the evaporation of a liquid deposited on the skin. This device, however, uses means, such as a liquid tank, a fan, which increase the size and the cost of the device.
D'autres dispositifs antidouleur pour l'épilation sont connus des documents DE 44 08 809 et WO 98/55000 qui décrivent des moyens de stimulation électrique de la peau, par l'envoi des impulsions électriques, respectivement des décharges électriques sur la zone à épiler. Ces dispositifs s'avèrent d'une efficacité limitée, tout en étant complexes et d'un coût élevé.Other pain-relieving devices for hair removal are known from documents DE 44 08 809 and WO 98/55000 which describe means of electrical stimulation of the skin, by sending electrical pulses, respectively electrical discharges to the area to be epilated. . These devices prove to be of limited effectiveness, while being complex and of high cost.
L'efficacité des dispositifs antidouleur utilisés en association avec des appareils d'épilation a été beaucoup améliorée par l'utilisation de la stimulation mécanique vibratoire de la peau simultanément à l'épilation.The effectiveness of pain relief devices used in combination with hair removal devices has been greatly improved by the use of mechanical vibratory stimulation of the skin simultaneously with hair removal.
Ainsi, les documents EP 0 671 136 et WO 99/13750 au nom de la demanderesse décrivent des picots et des brosses montés fixes sur le rouleau rotatif portant les pinces. Les brosses et les picots sont supportés par une zone allongée en creux s'étendant parallèlement à l'alignement des pinces du rouleau rotatif. Les brosses ont un effet de redressement des poils avant l'épilation, pendant que les picots produisent sur la peau un effet de massage, plus ou moins accentué engendrant une sensation de douleur qui masque la douleur de l'épilation. Cependant, les brosses et surtout les picots restent assez longtemps en contact avec la peau et ils produisent un effet de frottement sur cette dernière, effet qui peut occasionner des irritations.Thus, documents EP 0 671 136 and WO 99/13750 in the name of the Applicant describe pins and brushes fixedly mounted on the rotary roller carrying the pliers. The brushes and the pins are supported by an elongated recessed area extending parallel to the alignment of the clamps of the rotary roller. The brushes have an effect of straightening the bristles before depilation, while the pins produce a massage effect on the skin, more or less accentuated generating a sensation of pain which masks the pain of depilation. However, the brushes and especially the spikes remain in contact with the skin for quite a long time and they produce a friction effect on the latter, an effect which can cause irritation.
On a également proposé dans le document WO 97/00032 un épilateur à pinces rotatives comportant une série de roulettes mobiles poussées radialement par la force centrifuge et/ou par des ressorts, roulettes qui appliquent des impulsions mécaniques sur la peau afin de camoufler la douleur provoquée par l'arrachage des poils. Cette solution s'avère pourtant compliquée, elle nécessite également des précisions d'exécution et des coûts élevés pour ses composants.WO 97/00032 has also proposed a rotary pliers epilator comprising a series of movable rollers pushed radially by centrifugal force and / or by springs, rollers which apply mechanical impulses to the skin in order to camouflage the pain caused by pulling out the hairs. This solution is however complicated, it also requires precision and high costs for its components.
D'autres épilateurs comportant des dispositifs de stimulation vibratoire de la peau ont été proposés dans les documents tel EP 0 493 849, où une grille vibrante coiffe les moyens d'épilation, ou dans EP 0 760 219 où le boîtier de l'appareil comporte un cadre vibrant ou des rouleaux vibrants additionnels, le cadre ou les rouleaux étant agencés à côté du rouleau à pinces. Ces moyens vibreurs ont comme principaux désavantages de masquer la zone à épiler et de faire appel à des mécanismes additionnels pour leur entraînement.Other epilators comprising vibratory stimulation devices for the skin have been proposed in documents such as EP 0 493 849, where a vibrating grid covers the epilation means, or in EP 0 760 219 where the housing of the device comprises a vibrating frame or additional vibrating rollers, the frame or the rollers being arranged next to the gripper roller. The main disadvantages of these vibrating means are to mask the area to be depilated and to use additional mechanisms for training them.
Le document WO 97/19613 décrit un épilateur comportant un peigne ou une main à picots flexibles, montés vibrants sur le boîtier, en dehors du rouleau à pinces. Cependant, cette solution nécessite un mécanisme de mise en vibration encore plus élaboré, donc complexe.Document WO 97/19613 describes an epilator comprising a comb or a hand with flexible pins, vibrating mounted on the housing, outside of the clamp roller. However, this solution requires an even more sophisticated, therefore complex, vibration mechanism.
Le document FR 2 745 992 au nom de la demanderesse décrit un épilateur dont le rouleau d'épilation est entouré par un étrier monté vibrant sur le boîtier. Même si les moyens d'entraînement en vibration se trouvent un peu simplifiés par rapport aux réalisations précédentes, il n'en reste pas moins que les pièces en vibration masquent également la zone à épiler, ce qui est gênant pour l'utilisatrice.Document FR 2 745 992 in the name of the applicant describes an epilator, the depilation roller of which is surrounded by a stirrup mounted vibrating on the housing. Even if the vibration drive means are somewhat simplified by compared to previous embodiments, the fact remains that the vibrating parts also mask the area to be epilated, which is inconvenient for the user.
Le but de l'invention est de remédier, au moins en partie, aux inconvénients susmentionnés et de proposer un appareil à épiler à pinces destiné à appliquer des stimulations vibratoires sur la zone à épiler sensiblement en même temps que l'arrachage des poils de manière à masquer efficacement la douleur ressentie pendant l'épilation.The object of the invention is to remedy, at least in part, the abovementioned drawbacks and to propose a tweezer with tweezers intended to apply vibratory stimulation to the area to be epilated substantially at the same time as the pulling of the hairs so to effectively mask the pain felt during hair removal.
Une solution a été proposée dans la demande de brevet FR 9908885 au nom de la demanderesse. Cette demande de brevet décrit un appareil à épiler comportant un ensemble formé par le rouleau à pinces, le moteur et le système de transmission, l'ensemble étant monté flottant par rapport au boîtier de l'appareil. Ledit ensemble comporte par ailleurs une pièce à balourd qui est mise en rotation lors du fonctionnement de l'appareil de manière à ce qu'elle génère des vibrations dans le rouleau à pinces, vibrations qui stimulent la peau lors de l'épilation. Fonctionnant à satisfaction au niveau de la stimulation vibratoire antidouleur de la peau, on s'est rendu compte que les vibrations n'étaient pas complètement amorties dans le boîtier de l'appareil et qu'elles occasionnaient des sensations désagréables dans la main de l'utilisatrice.A solution was proposed in patent application FR 9908885 in the name of the applicant. This patent application describes an epilating appliance comprising an assembly formed by the pliers roller, the motor and the transmission system, the assembly being mounted floating relative to the housing of the appliance. Said assembly also includes an unbalanced part which is rotated during the operation of the device so that it generates vibrations in the clamp roller, vibrations which stimulate the skin during depilation. Operating satisfactorily with the pain-relieving vibration stimulation of the skin, we realized that the vibrations were not completely damped in the housing of the device and that they caused unpleasant sensations in the hand of the wearer.
Le but de la présente invention est de proposer un appareil à épiler à rouleau à pinces comportant des moyens aptes à générer de manière efficace des vibrations dans ledit rouleau tout en assurant un bon amortissement des vibrations dans le boîtier de l'appareil.The object of the present invention is to provide a tweezer roller with pliers comprising means capable of effectively generating vibrations in said roller while ensuring good absorption of vibrations in the housing of the appliance.
Un autre but de l'invention est un appareil à épiler muni de moyens antidouleur fiables, de construction simple et qui se prêtent à une fabrication en grande série, pour des coûts de fabrications moindres.Another object of the invention is a hair-removing device provided with reliable pain relief means, of simple construction and which lend themselves to mass production, for lower manufacturing costs.
Un but supplémentaire de l'invention est un appareil à épiler à moyens antidouleur qui agissent simultanément à l'arrachage, tout en laissant visible la zone à épiler.A further object of the invention is a hair-removing device with pain-relieving means which act simultaneously with the removal, while leaving visible the epilating area.
Ces buts sont atteints avec un appareil à épiler pour éliminer les poils corporels comportant un rouleau monté rotatif dans un boîtier destiné à être tenu à la main, ledit rouleau comportant au moins deux pinces destinées à serrer et arracher les poils, le rouleau étant susceptible d'être entraîné en rotation par un moteur électrique via un système de transmission, du fait que l'ensemble formé par le rouleau, le système de transmission et le moteur est divisé en deux parties, chaque partie étant solidaire d'un support monté flottant par rapport au boîtier et étant entraînée en vibration à une fréquence prédéterminée, la fréquence de vibration de l'une des parties étant en opposition de phase par rapport à celle de l'autre partie.These aims are achieved with a depilatory device for removing body hair, comprising a roller rotatably mounted in a housing intended to be held in the hand, said roller comprising at least two pliers intended to clamp and pluck the hairs, the roller being capable of '' be rotated by an electric motor via a transmission system, since the assembly formed by the roller, the transmission system and the motor is divided into two parts, each part being integral with a support mounted floating by relative to the housing and being driven in vibration at a predetermined frequency, the vibration frequency of one of the parts being in phase opposition with respect to that of the other part.
Ainsi, les moyens d'entraînement en rotation du rouleau d'épilation sont également prévus pour générer des vibrations dans le rouleau en même temps que l'arrachage. La sollicitation vibratoire de la peau produit donc un effet antalgique simultanément au processus d'épilation réduisant la douleur tout au long de ce processus. Alors, afin d'empêcher la transmission de ces vibrations au boîtier et d'ici dans la main de l'utilisatrice, on sollicite également en vibration, à la même fréquence, mais en opposition de phase, les autres pièces en mouvement du mécanisme d'entraînement du rouleau. Des moyens sont prévus pour maintenir en contact l'ensemble lors du fonctionnement.Thus, the means for driving the depilation roller in rotation are also provided for generating vibrations in the roller at the same time as the removal. The vibratory stress on the skin therefore produces an analgesic effect simultaneously with the hair removal process, reducing pain throughout this process. So, in order to prevent the transmission of these vibrations to the housing and from here into the user's hand, the other moving parts of the mechanism are also vibrated, at the same frequency, but in phase opposition. roller drive. Means are provided for keeping the assembly in contact during operation.
L'ensemble formé par le rouleau, le système de transmission et le moteur électrique d'actionnement est donc scindé en deux parties qui vibrent à la même fréquence, en opposition de phase, parties qui sont montées sur des supports montés flottants par rapport au boîtier de manière à ce qu'ils puissent vibrer indépendamment l'un de l'autre. Par conséquent, au moment de l'entraînement en vibration des deux parties les vibrations d'une première partie, notamment du rouleau annulent celles de la deuxième partie, notamment du moteur, de manière à ce que les vibrations se trouvent complètement neutralisées par rapport à un repère fixe, notamment le boîtier. Avantageusement, l'ensemble formé par le rouleau, le système de transmission et le moteur est scindé en deux parties de masses sensiblement égales.The assembly formed by the roller, the transmission system and the electric actuating motor is therefore split into two parts which vibrate at the same frequency, in phase opposition, parts which are mounted on supports mounted floating relative to the housing. so that they can vibrate independently of each other. Consequently, at the time of the vibration drive of the two parts, the vibrations of a first part, in particular of the roller cancel those of the second part, in particular of the motor, so that the vibrations are completely neutralized with respect to a fixed mark, in particular the housing. Advantageously, the assembly formed by the roller, the transmission system and the motor is split into two parts of substantially equal masses.
Ainsi, les paramètres des vibrations générées dans ces deux parties, notamment l'amplitude, peuvent être mieux contrôlés, surtout quand on utilise un moyen unique de mise en vibration qui fait osciller en même temps les deux parties.Thus, the parameters of the vibrations generated in these two parts, in particular the amplitude, can be better controlled, especially when using a single means of setting in vibration which makes the two parts oscillate at the same time.
De préférence, la fréquence des vibrations produites dans le rouleau rotatif est supérieure à 50 Hz.Preferably, the frequency of the vibrations produced in the rotary roller is greater than 50 Hz.
Des études médicales théoriques et appliquées ont en effet établi que l'effet antalgique est une fonction de la fréquence de la stimulation vibratoire. Dans le cadre de l'invention, la fréquence peut être choisie avantageusement par la vitesse de rotation de la pièce à balourd.Theoretical and applied medical studies have indeed established that the analgesic effect is a function of the frequency of vibratory stimulation. In the context of the invention, the frequency can be advantageously chosen by the speed of rotation of the unbalanced part.
Avantageusement, les moyens élastiques de montage de l'ensemble dans le boîtier et la pièce en mouvement sont déterminés de telle sorte que l'amplitude des vibrations soit comprise entre 0,1 mm et 1 mm, préférentiellement 0,5 mm.Advantageously, the elastic means for mounting the assembly in the housing and the moving part are determined so that the amplitude of the vibrations is between 0.1 mm and 1 mm, preferably 0.5 mm.
Il a été montré qu'une telle amplitude appliquée avec une fréquence supérieure à 50 Hz, masque la douleur due à l'épilation.It has been shown that such an amplitude applied with a frequency greater than 50 Hz masks the pain due to epilation.
De préférence, la pièce en mouvement génère des vibrations du rouleau rotatif dans une direction sensiblement perpendiculaire à la peau.Preferably, the moving part generates vibrations of the rotating roller in a direction substantially perpendicular to the skin.
Le rouleau rotatif vient donc frapper verticalement la peau, les vibrations étant entièrement absorbées par cette dernière, ce qui assure un effet antalgique efficace. Les mouvements oscillatoires en opposition de phase sont produits facilement dans le sens longitudinal du boîtier.The rotary roller therefore strikes the skin vertically, the vibrations being entirely absorbed by the latter, which provides an effective analgesic effect. Oscillatory movements in phase opposition are easily produced in the longitudinal direction of the case.
Selon un mode avantageux de réalisation de l'invention, les supports des parties en mouvement sont actionnés par des moyens de mise en vibration intégrés au système de transmission.According to an advantageous embodiment of the invention, the supports of the moving parts are actuated by means of vibrating integrated into the transmission system.
On aurait pu réaliser des systèmes de mise en vibration notamment sous forme des deux masselottes solidaires, l'une du rouleau d'épilation et produisant des vibrations d'une certaine fréquence et amplitude dans ce dernier, et l'autre solidaire du moteur et/ou du système de transmission et vibrant à la même fréquence, mais déphasée de 180°.Vibration systems could have been produced in particular in the form of two integral weights, one of the epilating roller and producing vibrations of a certain frequency and amplitude in the latter, and the other integral with the motor and / or the transmission system and vibrating at the same frequency, but 180 ° out of phase.
Pour des raisons de simplicité de la construction et d'efficacité de l'entraînement, on a choisi d'intégrer les moyens vibrants au système de transmission du mouvement du moteur au rouleau d'épilation.For reasons of simplicity of construction and efficiency of the drive, it has been chosen to integrate the vibrating means into the system for transmitting the movement of the motor to the epilating roller.
Avantageusement, lesdits moyens de mise en vibration sont constitués par une pièce rotative dont l'axe de rotation est monté fixe par rapport au boîtier, ladite pièce rotative comportant une première denture prévue pour coopérer avec une première roue dentée solidaire du premier support et une deuxième denture prévue pour coopérer avec une deuxième roue dentée solidaire du deuxième support, le centre de la section transversale de chaque denture étant décalé de part et d'autre de l'axe commun de rotation dans une direction perpendiculaire à ce dernier.Advantageously, said means for vibrating consist of a rotary part whose axis of rotation is mounted fixed relative to the housing, said rotary part comprising a first toothing provided for cooperating with a first toothed wheel secured to the first support and a second toothing provided to cooperate with a second toothed wheel secured to the second support, the center of the cross section of each toothing being offset on either side of the common axis of rotation in a direction perpendicular to the latter.
Les masses en mouvement sont scindées en deux parties, chacune des parties étant solidaire d'un support monté flottant par rapport au boîtier de manière à ce que chaque support puisse être entraîné en vibration séparément. On aurait pu prévoir un système à deux ou plusieurs cames roulant l'une sur l'autre, chacune appartenant à l'une desdites parties, de manière à recevoir le mouvement du train d'engrenages et à entraîner par la suite chaque support en vibration.The moving masses are split into two parts, each part being integral with a support mounted floating relative to the housing so that each support can be driven in vibration separately. One could have provided a system with two or more cams rolling one on the other, each belonging to one of said parts, so as to receive the movement of the gear train and to subsequently drive each support in vibration. .
On a quand même choisi d'utiliser une pièce rotative munie d'au moins une denture car elle peut être intégrée facilement au système de transmission ou train d'engrenages, cette pièce pouvant être mise en rotation par une roue voisine ou par l'axe de sortie du moteur. De surcroît, les paramètres constructifs de cette pièce, notamment les diamètres, vitesses, modules de ses dentures respectives peuvent être calculés de manière à obtenir une vitesse de fonctionnement du rouleau et une fréquence des vibrations prédéterminées de ce dernier.We nevertheless chose to use a rotating part provided with at least one toothing because it can be easily integrated into the transmission system or gear train, this part being able to be rotated by a neighboring wheel or by the axle. motor output. In addition, the constructive parameters of this part, in particular the diameters, speeds, modules of its teeth can be calculated so as to obtain an operating speed of the roller and a predetermined vibration frequency of the latter.
Ainsi, lors de la mise en rotation de la pièce et de ses dentures, ces dernières transmettent à la roue ou aux roues qu'elles engrènent un déséquilibre équivalent à la valeur de leur décalage ou de l'excentration par rapport à l'axe de rotation, déséquilibre absorbé par le support flottant de chacune des roues. Par conséquent, chaque support effectue un mouvement de translation dans la direction de l'excentration respective, de manière à ce que l'on obtienne des déplacements en sens opposés des deux supports.Thus, when the part and its teeth are rotated, the latter transmit to the wheel or wheels that they generate an imbalance equivalent to the value of their offset or of the eccentricity with respect to the axis of rotation, imbalance absorbed by the floating support of each of the wheels. Consequently, each support performs a translational movement in the direction of the respective eccentricity, so that displacements in opposite directions are obtained from the two supports.
Avantageusement, la première denture présente une excentration de valeur égale, mais diamétralement opposée à l'excentration de la deuxième denture.Advantageously, the first toothing has an eccentricity of equal value, but diametrically opposite to the eccentricity of the second toothing.
Dans ce cas, les vibrations obtenues dans chacun des supports flottants, et donc dans les deux parties en mouvement dudit ensemble, ont des amplitudes égales mais de sens contraire et, par conséquent, elles se neutralisent réciproquement.In this case, the vibrations obtained in each of the floating supports, and therefore in the two moving parts of said assembly, have equal amplitudes but in opposite directions and, consequently, they mutually neutralize each other.
Avantageusement, la valeur de l'excentration de chaque denture par rapport à son axe de rotation correspond à la moitié de l'amplitude des vibrations obtenues dans chacun des supports.Advantageously, the value of the eccentricity of each toothing relative to its axis of rotation corresponds to half the amplitude of the vibrations obtained in each of the supports.
De par sa construction, la pièce rotative à deux dentures décalées induit des vibrations d'amplitudes égales, mais en sens opposés dans chacun des supports. Lors de la rotation des deux dentures, au moment où la distance entre la périphérie de la première denture et la périphérie de la deuxième denture est maximale, les deux dentures agissent sur les supports flottants en les éloignant l'un de à l'autre. L'amplitude des vibrations obtenues dans ce cas est maximale et elle est représentée par la somme des excentrations des deux dentures, notamment deux fois l'une d'entre elles pour des valeurs égales des deux excentrations. De préférence, le réglage des excentrations des dentures se fait de manière à ce que l'amplitude maximale des vibrations est obtenue lorsque les pinces d'épilation sont en position fermée.By its construction, the rotating part with two offset teeth induces vibrations of equal amplitudes, but in opposite directions in each of the supports. When the two teeth rotate, when the distance between the periphery of the first teeth and the periphery of the second teeth is maximum, the two teeth act on the floating supports by moving them away from each other. The amplitude of the vibrations obtained in this case is maximum and it is represented by the sum of the eccentricities of the two teeth, in particular twice one of them for equal values of the two eccentricities. Preferably, the eccentricity of the teeth is adjusted so that the maximum amplitude of the vibrations is obtained when the tweezers are in the closed position.
Ainsi, l'amplitude maximale de la stimulation est obtenue juste avant l'arrachage des poils, ce qui confère une stimulation de la peau très efficace.Thus, the maximum amplitude of the stimulation is obtained just before the plucking of the hairs, which gives a very effective stimulation of the skin.
Dans une variante avantageuse de l'invention, les supports sont montés coulissants sur des guidages dans le boîtier.In an advantageous variant of the invention, the supports are slidably mounted on guides in the housing.
Ceci oriente les mouvements en vibration sensiblement en une seule direction, notamment perpendiculaire à la peau, tout en assurant la stabilité des masses en vibration.This directs the vibrating movements substantially in one direction, in particular perpendicular to the skin, while ensuring the stability of the vibrating masses.
D'autres caractéristiques et avantages de l'invention apparaîtront plus clairement à la lumière de la description et des dessins qui suivent, illustrant, à titre d'exemples non limitatifs, des modes de mise en œuvre de l'invention. Ainsi, référence est faite aux figures 1 à 4, où :Other characteristics and advantages of the invention will appear more clearly in the light of the description and of the drawings which follow, illustrating, by way of nonlimiting examples, embodiments of the invention.

Les figures annexées illustrent un appareil d'épilation de la peau humaine muni de moyens de mise en vibration du rouleau rotatif ou de la tête à épiler 5 de cet appareil de telle sorte que les ondes cycliques issues de ces vibrations provoquent un effet antidouleur sur la zone à épiler. Un exemple d'appareil d'épilation à l'intérieur duquel ont été intégrés des moyens de mise en vibration, notamment de la tête d'épilation de l'appareil, est décrit dans le document FR 2 758 060 au nom de la demanderesse. Il est cependant évident que cet appareil ne constitue qu'un exemple d'utilisation de moyens antidouleur selon l'invention, car tout appareil d'épilation à pinces d'arrachage, peut être adapté dans le but de lui intégrer des moyens antidouleur de l'invention.The appended figures illustrate a device for depilating human skin provided with means for vibrating the rotary roller or the depilatory head 5 of this device so that the cyclic waves resulting from these vibrations cause a pain-relieving effect on the epilating area. An example of a hair removal device inside which have been integrated vibrating means, in particular of the hair removal head of the device, is described in document FR 2 758 060 in the name of the applicant. It is however obvious that this device is only one example of the use of pain relief means according to the invention, since any hair removal device with pliers, can be adapted with the aim of integrating pain relief means therein. 'invention.
Sur les figures 1 à 3 on peut remarquer un appareil d'épilation comprenant un rouleau rotatif 5 muni d'un arbre central mobile en rotation dans un berceau 20 et d'une cage montée coaxialement sur l'arbre qu'elle entoure, cette cage étant formée par deux flasques latéraux 21 ,22 tenant entre eux quatre tiges 23.In Figures 1 to 3 we can notice a hair removal device comprising a rotary roller 5 provided with a central shaft movable in rotation in a cradle 20 and a cage mounted coaxially on the tree it surrounds, this cage being formed by two lateral flanges 21, 22 holding between them four rods 23.
Le flasque gauche 21 est solidaire d'un pignon 13 en prise avec un train d'engrenages réducteur ou système de transmission 12 entraîné par un pignon 9 solidaire de l'arbre de sortie d'un moteur d'entraînement 8.The left flange 21 is secured to a pinion 13 engaged with a reduction gear train or transmission system 12 driven by a pinion 9 secured to the output shaft of a drive motor 8.
Deux séries de lames cruciformes alternées 5a, respectivement 5b, sont montées sur l'arbre central du rouleau rotatif 5, chaque paire de lames alternées 5a,5b formant une pince d'épilation, dont une lame mobile 5a est susceptible de s'écarter d'une lame fixe 5b et, alternativement, de s'appliquer contre celle-ci. L'actionnement de la lame mobile 5a provoque l'ouverture, respectivement la fermeture de la pince d'épilation, afin de serrer les poils et les arracher, et de les relâcher après arrachement, ceci au fur et au mesure de la rotation du rouleau 5. Ainsi, les poils de la zone à épiler se présentant devant une fenêtre 24 du boîtier 1, sont arrachés suite à la rotation du rouleau ou de la tête d'épilation 5.Two series of alternating cruciform blades 5a, respectively 5b, are mounted on the central shaft of the rotary roller 5, each pair of alternating blades 5a, 5b forming a tweezer, from which a movable blade 5a is capable of deviating from 'A fixed blade 5b and, alternatively, to apply against it. The actuation of the movable blade 5a causes the opening, respectively the closing, of the depilatory forceps, in order to tighten the hairs and pull them out, and to release them after pulling out, this as the roller rotates. 5. Thus, the bristles of the area to be epilated appearing in front of a window 24 of the housing 1 are pulled out following the rotation of the roller or of the epilation head 5.
Avantageusement, la tête d'épilation 5 peut présenter des brosses 25 et/ou des picots 26 agencés dans la zone allongée en creux s'étendant parallèlement à l'alignement des lames 5a, 5b. Les brosses 25 ont le rôle de redresser les poils en vue de leur arrachage, pendant que les picots 26 évitent que la tête d'épilation 5 saute sur la peau au passage de la zone en creux.Advantageously, the epilation head 5 can have brushes 25 and / or pins 26 arranged in the recessed elongated zone extending parallel to the alignment of the blades 5a, 5b. The brushes 25 have the role of straightening the bristles with a view to pulling them out, while the pins 26 prevent the depilation head 5 from jumping on the skin when passing through the hollow area.
Les figures 1 à 3 illustrent un mode préféré de réalisation de l'invention selon lequel le rouleau à pinces 5 et les roues 6 et 7 sont solidaires d'un premier support ou chariot supérieur 11a, pendant que le moteur 8 et son pignon de sortie 9 sont montés sur un deuxième support ou chariot inférieur 11 b.Figures 1 to 3 illustrate a preferred embodiment of the invention according to which the gripper roller 5 and the wheels 6 and 7 are integral with a first support or upper carriage 11a, while the motor 8 and its output pinion 9 are mounted on a second support or lower carriage 11b.
Tel que mieux visible aux figures 2 et 3b, les supports ou chariots 11a et 11 b sont montés flottants par rapport au boîtier 1 de l'appareil. Plus précisément, les supports 11a,11 b sont montés coulissants, à rencontre des ressorts de rappel 10, sur des tiges de guidage 4a,4b montées fixes dans les bras 14a, 14b, 14c, 14d de l'étrier 2.As best seen in Figures 2 and 3b, the supports or carriages 11a and 11b are mounted floating relative to the housing 1 of the device. More specifically, the supports 11a, 11b are slidably mounted, meeting the return springs 10, on guide rods 4a, 4b fixedly mounted in the arms 14a, 14b, 14c, 14d of the stirrup 2.
Dans le système de transmission ou train d'engrenages 12 est intercalée une pièce rotative 3 ou une roue à deux dentures 3a et 3b. La pièce rotative 3 est montée sur un axe de rotation A solidaire du boîtier 1 , axe supporté en rotation dans le palier 18 de l'étrier 2. L'étrier 2 est directement fixé au boîtier 1 de l'appareil moyennant des vis de fixation, des rivets ou d'autres moyens de fixation démontables ou non-démontables.In the transmission system or gear train 12 is interposed a rotating part 3 or a wheel with two teeth 3a and 3b. The rotating part 3 is mounted on an axis of rotation A integral with the housing 1, axis supported in rotation in the bearing 18 of the bracket 2. The bracket 2 is directly fixed to the housing 1 of the device by means of fixing screws , rivets or other removable or non-removable fastening means.
Les deux dentures 3a, 3b sont de préférence solidaires d'une même pièce 3 dont une première denture 3a est prévue pour coopérer avec le pignon 9 solidaire de l'axe de sortie du moteur 8, et la deuxième denture 3b est destinée à s'engrener avec la roue dentée 7 et transmettre plus loin le mouvement de rotation du moteur 8, dans le système de transmission 12 jusque dans le rouleau 5.The two teeth 3a, 3b are preferably integral with the same part 3, a first toothing 3a of which is provided to cooperate with the pinion 9 secured to the output axis of the motor 8, and the second toothing 3b is intended to be s mesh with the toothed wheel 7 and transmit further the rotational movement of the motor 8, in the transmission system 12 as far as in the roller 5.
Plus particulièrement selon l'invention, l'axe central de chaque denture est décalé par rapport à l'axe général de rotation A de la pièce rotative 3. Tel que mieux visible aux figures 4a ou 4b, la denture 3a est décalée d'une valeur « e » par rapport à l'axe A dans une direction perpendiculaire à ce dernier et la denture 3b présente une excentration de même valeur, mais disposée à 180° par rapport au premier.More particularly according to the invention, the central axis of each toothing is offset relative to the general axis of rotation A of the rotary part 3. As best seen in Figures 4a or 4b, the toothing 3a is offset by value "e" relative to the axis A in a direction perpendicular to the latter and the teeth 3b have an eccentricity of the same value, but disposed at 180 ° relative to the first.
A la figure 3a on peut remarquer que le support ou chariot supérieur 11a comporte des paliers 16 et 17 pour supporter en rotation les axes des engrenages 6 et 7 et qu'il supporte également le bâti 15 du rouleau 5. Le moteur 8 avec son pignon 9 sont fixés sur le support ou chariot inférieur 11b.In FIG. 3a, it can be noted that the upper support or carriage 11a has bearings 16 and 17 for rotationally supporting the axes of the gears 6 and 7 and that it also supports the frame 15 of the roller 5. The motor 8 with its pinion 9 are fixed on the support or lower carriage 11b.
Les ressorts 10 sont, de préférence, en nombre de quatre, deux pour chacun des supports 11 a,11 b. Les ressorts 10 sont hélicoïdaux cylindriques, ils sont montés sur les tiges 4a,4b avec l'une des extrémités fixée par des butées 14a, respectivement 14b,14c,14d par rapport à l'une des tiges 4a,4b, pendant que l'autre extrémité libre prend appui sur l'un des supports coulissants 11 a, 11 b. Ainsi, les résultantes des efforts respectifs des ressorts 10 ont tendance à rapprocher les deux supports 11 a et 11 b de manière à maintenir en contact les engrenages 7,3 et 9 du système de transmission 12.The springs 10 are preferably in number of four, two for each of the supports 11 a, 11 b. The springs 10 are helical cylindrical, they are mounted on the rods 4a, 4b with one of the ends fixed by stops 14a, respectively 14b, 14c, 14d relative to one of the rods 4a, 4b, while the another free end is supported on one of the sliding supports 11 a, 11 b. Thus, the results of the respective efforts of the springs 10 tend to bring the two supports 11 a and 11 b together so as to keep the gears 7, 3 and 9 of the transmission system 12 in contact.
Le boîtier 1 de l'appareil est réalisé de préférence en deux parties 1a, 1 b afin de faciliter le montage des divers composants de l'appareil. Les parties 1a, 1 b sont réalisés en une matière plastique par une technique de moulage. Les pignons ou engrenages du train d'engrenages 12 de l'appareil sont, de préférence réalisés en une matière plastique résistante à l'usure afin de réduire le poids total de l'appareil.The housing 1 of the device is preferably made in two parts 1a, 1b in order to facilitate the mounting of the various components of the device. Parts 1a, 1b are made of a plastic material by a molding technique. The pinions or gears of the gear train 12 of the device are preferably made of a wear-resistant plastic material in order to reduce the total weight of the device.
En fonctionnement, lors de la mise en marche du moteur 8, son mouvement de rotation est transmis, via le pignon 9, à la pièce rotative 3, notamment à la denture 3a de cette dernière.In operation, when the motor 8 is started, its rotational movement is transmitted, via the pinion 9, to the rotary part 3, in particular to the toothing 3a of the latter.
Au moment où la denture 3a est dans la position représentée à la figure 4a, avec l'excentration « e » située au-dessus de l'axe A, la denture 3b se présente avec son excentration « e » en dessous de l'axe A, ce qui fait que la distance « d » mesurée entre le point de contact de la denture 3a avec le pignon 9 et le point de contact de la denture 3b avec la roue 7 est à son minimum, cette distance étant inférieure à la somme des rayons des cercles primitifs des pignons 3a et 3b d'une valeur égale à deux fois celle de l'excentration « e ». Dans ce cas, les supports ou chariots supérieur 11a et inférieur 11 b, poussés par les ressorts 10, se trouvent dans leur position de rapprochement extrême. Le pignon 9 continue sa rotation et à une position située à 180° par rapport à celle décrite auparavant, et tel que représenté à la figure 4b, les excentrations des dentures 3a et 3b sont inversées. Ainsi l'excentration « e » de la denture 3a se trouve en dessous de l'axe A et celle de la denture 3b au-dessus du même axe, ce qui fait que la distance « D » entre leurs points des contacts avec les roues adjacentes atteint sa valeur maximale, cette distance étant égale à la somme des rayons des cercles primitifs des dentures 3a,3b majorée d'une valeur égale à deux fois celle de l'excentration « e ». Dans ce cas, les supports 11a et 11b se trouvent dans leur position d'éloignement extrême. On remarque que, les supports 11a, 11 b étant montés sur des ressorts 10, donc isolés du boîtier 1 , aucune des parties mobiles ne vient en contact avec le boîtier 1 lors du fonctionnement.When the toothing 3a is in the position shown in FIG. 4a, with the eccentricity “e” situated above the axis A, the toothing 3b is presented with its eccentricity “e” below the axis A, which means that the distance “d” measured between the point of contact of the toothing 3a with the pinion 9 and the point of contact of the toothing 3b with the wheel 7 is at its minimum, this distance being less than the sum radii of the original circles of the pinions 3a and 3b with a value equal to twice that of the eccentricity "e". In this case, the upper 11a and lower 11b supports or carriages, pushed by the springs 10, are in their position of extreme approximation. The pinion 9 continues its rotation and at a position situated at 180 ° with respect to that described previously, and as shown in FIG. 4b, the eccentricities of the teeth 3a and 3b are reversed. Thus the eccentricity “e” of the toothing 3a is located below the axis A and that of the toothing 3b above the same axis, which means that the distance “D” between their points of contact with the wheels adjacent reaches its maximum value, this distance being equal to the sum of the radii of the primitive circles of the teeth 3a, 3b increased by a value equal to twice that of the offset “e”. In this case, the supports 11a and 11b are in their position of extreme separation. Note that, the supports 11a, 11b being mounted on springs 10, therefore isolated from the housing 1, none of the movable parts comes into contact with the housing 1 during operation.
Après encore une rotation de 180°, les dentures reviennent dans leur position représentée à la figure 4a. On constate donc que la position des deux supports ou chariots 11a, 11b et, par conséquent, celle des composants de l'appareil solidaires de chacun desdits supports, oscille entre ces deux positions extrêmes, celle de rapprochement représentée à la figure 4a et celle d'éloignement de la figure 4b. Il en résulte des mouvements de va-et-vient dans les deux supports 11a et 11b d'une fréquence prédéterminée et d'une amplitude égale à deux fois l'excentration « e », les vibrations produites étant en opposition de phase l'une, notamment celle du support 11a, par rapport à l'autre, celle du support 11 b. A titre d'exemple nullement limitatif, pour une valeur de l'excentration « e » de 0.25 mm, l'amplitude des vibrations produites dans la tête d'épilation est de 0.5 mm.After another 180 ° rotation, the teeth return to their position shown in Figure 4a. It can therefore be seen that the position of the two supports or carriages 11a, 11b and, consequently, that of the components of the apparatus secured to each of said supports, oscillates between these two extreme positions, that of approximation shown in FIG. 4a and that of distance from Figure 4b. This results in back-and-forth movements in the two supports 11a and 11b of a predetermined frequency and of an amplitude equal to twice the offset “e”, the vibrations produced being in phase opposition one , in particular that of the support 11a, relative to the other, that of the support 11b. By way of non-limiting example, for a value of the offset “e” of 0.25 mm, the amplitude of the vibrations produced in the epilation head is 0.5 mm.
De préférence, l'axe fixe A ainsi que les centres de masse de chacun des supports 11a,11 b se situent dans le plan de symétrie vertical de l'appareil. Dans ce cas, les ressorts 10 sont identiques, ils ont la même constante de raideur et les mêmes dimensions.Preferably, the fixed axis A and the centers of mass of each of the supports 11a, 11b are located in the vertical plane of symmetry of the device. In this case, the springs 10 are identical, they have the same stiffness constant and the same dimensions.
Avantageusement, les paramètres des engrenages du système de transmission 12 sont calculés de manière à obtenir dans le rouleau à pinces 5 des vibrations à une fréquence supérieure à 50 Hz qui est considéré comme seuil de la fréquence anti-douleur. A titre d'exemple, pour une vitesse de rotation du moteur de 7200 rot/min, on obtient, avec un appareil du type décrit, des vibrations à une fréquence de 120Hz dans la tête d'épilation 5.Advantageously, the parameters of the gears of the transmission system 12 are calculated so as to obtain in the gripper roller 5 vibrations at a frequency greater than 50 Hz which is considered as the frequency threshold. Pain killer. By way of example, for an engine rotation speed of 7200 rot / min, vibrations are obtained at a frequency of 120 Hz in an epilation head 5 with an apparatus of the type described.
Afin d'obtenir la stimulation vibratoire de la peau avant la phase d'arrachage des poils, la tête d'épilation 5 doit frapper la peau au moment où les pinces sont en position fermée. Ainsi, la position des excentrations des deux dentures est telle que l'amplitude maximale des vibrations est obtenue juste après la fermeture des pinces, cette position étant représenté à la figure 4b.In order to obtain vibratory stimulation of the skin before the phase of plucking the hairs, the epilation head 5 must strike the skin when the forceps are in the closed position. Thus, the position of the eccentricities of the two teeth is such that the maximum amplitude of the vibrations is obtained just after the clamps have been closed, this position being shown in FIG. 4b.
Ainsi, dans le cas d'un appareil à épiler plus particulièrement décrit dans le document FR 2 758 060 au nom de la demanderesse, le rouleau 5 porte sur sa périphérie quatre rangées de pinces. De ce fait, la pièce rotative ou roue 3 doit avoir une vitesse de rotation quatre fois supérieure à la vitesse de rotation du rouleau 5 et le calage des excentrations doit être fait de façon à ce que les pinces 5a, 5b se trouvent toujours en contact avec la peau lors de leur fermeture.Thus, in the case of a depilatory device more particularly described in document FR 2 758 060 in the name of the applicant, the roller 5 carries on its periphery four rows of pliers. Therefore, the rotating part or wheel 3 must have a rotation speed four times greater than the rotation speed of the roller 5 and the setting of the eccentricities must be done so that the clamps 5a, 5b are always in contact with the skin when closed.
D'autres variantes de réalisation de l'invention peuvent être réalisées sans sortir du cadre de ses revendications.Other alternative embodiments of the invention can be carried out without departing from the scope of its claims.
Notamment la pièce rotative 3 comportant une double denture 3a, 3b pourrait être une roue dentée composée de l'assemblage de deux roues 3a, 3b de diamètre primitif différent .In particular the rotary part 3 comprising a double toothing 3a, 3b could be a toothed wheel composed of the assembly of two wheels 3a, 3b of different pitch diameter.
La pièce rotative ou roue à deux dentures décalées peut être éventuellement remplacée par une roue ou un engrenage comportant des pignons concentriques à leur axe de rotation, d'autres moyens pouvant être employés pour mettre en vibrations les deux supports et leur composants. Ces moyens peuvent être, par exemple, deux balourds fonctionnant en opposition de phase, chacun étant solidaire d'un des supports flottants. On pourrait également utiliser tout autre moyen apte à produire des vibrations en rotation ou en translation, mais en opposition de phase dans chacun des supports flottants. The rotary part or wheel with two offset teeth can optionally be replaced by a wheel or a gear comprising pinions concentric with their axis of rotation, other means being able to be used to vibrate the two supports and their components. These means can be, for example, two unbalances operating in phase opposition, each being integral with one of the floating supports. One could also use any other means capable of producing vibrations in rotation or in translation, but in phase opposition in each of the floating supports.
