Description

Domaine technique de l'inventionTechnical field of the invention

La présente invention concerne le domaine technique des appareils de soins corporels électriques et, plus particulièrement, le domaine des appareils électriques d'épilation mécanique encore appelés épilateurs.The present invention relates to the technical field of electrical body care appliances and, more particularly, the field of mechanical electrical depilatory appliances also called epilators.

Etat de la technique antérieure :State of the prior art:

Les appareils d'épilation connus comprennent généralement un boîtier sur lequel est adaptée une tête d'épilation amovible entraînée en rotation via un train d'engrenage par un moteur électrique disposé dans le boîtier comme cela est par exemple décrit dans les documents FR 2 926 962 et EP 1 884 174 .Known epilation apparatus generally comprise a housing on which is fitted a removable depilatory head driven in rotation by a gear train by an electric motor arranged in the housing as is for example described in the documents FR 2 926 962 and EP 1 884 174 .

Les appareils d'épilation connus présentent l'inconvénient d'être relativement complexes en raison du caractère amovible de la tête. De plus, les appareils connus mettent en oeuvre un grand nombre de pièces ce qui en rend la fabrication et l'assemblage relativement onéreux. Ainsi, il est apparu le besoin d'un appareil d'épilation qui présente une durée de fabrication plus rapide et un coût de fabrication inférieur à celui des appareils connus tout en offrant des performances comparables et une fiabilité analogue voire supérieure.Known epilation devices have the disadvantage of being relatively complex because of the removable nature of the head. In addition, the known devices implement a large number of parts which makes the manufacture and assembly relatively expensive. Thus, there has emerged the need for an epilation device which has a faster manufacturing time and lower manufacturing cost than known devices while offering comparable performance and similar reliability or even higher.

Exposé de l'invention:Presentation of the invention

Afin d'atteindre cet objectif l'invention concerne un appareil d'épilation électrique comprenant un corps creux qui renferme un moteur électrique associé à un train d'engrenage entrainant en rotation une tête d'épilation mécanique rotative. Selon l'invention cet appareil d'épilation est caractérisé en ce que le corps est constitué de deux demi-coques monobloc qui sont assemblées l'une sur l'autre et qui délimitent ensemble une chambre d'épilation qui est ouverte au niveau d'une fenêtre d'épilation délimitée par un bord de chaque demi-coque et à l'intérieur de laquelle est disposée la tête d'épilation de manière à affleurer au niveau de la fenêtre d'épilation, l'une au moins des demi-coques intégrant des paliers de support de la tête d'épilation et/ou du train d'engrenage et/ou des nervures d'immobilisation du moteur électrique.In order to achieve this object the invention relates to an electric hair removal apparatus comprising a hollow body which encloses an electric motor associated with a gear train driving in rotation a rotating mechanical epilation head. According to the invention, this depilatory apparatus is characterized in that the body consists of two half-shells monobloc which are assembled one on the other and which delimit together a depilation chamber which is open at the level of a hair removal window delimited by an edge of each half-shell and inside which the epilation head is disposed so as to be flush with the epilation window, at least one of the half-shells incorporating support bearings of the epilation head and / or the gear train and / or ribs immobilizing the electric motor.

La mise en oeuvre d'un corps formé exclusivement de deux demi-coques monoblocs assurant les fonctions de confinement et de maintien des différents organes et pièces constitutifs de l'appareil d'épilation permet, grâce à la simplification obtenue, de réduire substantiellement le coût de fabrication et de diminuer substantiellement la durée de fabrication de l'appareil d'épilation selon l'invention par rapport aux appareils de l'épilation selon l'art antérieur.The implementation of a body formed exclusively of two one-piece half-shells providing the functions of confinement and maintenance of the various organs and parts constituting the epilation apparatus makes it possible, by virtue of the simplification obtained, to substantially reduce the cost of manufacturing and substantially reduce the manufacturing time of the depilatory device according to the invention compared to hair removal apparatus according to the prior art.

Il doit être remarqué que le caractère monobloc des demi-coques n'exclut pas qu'elles puissent être fabriquées en faisant intervenir plusieurs étapes de moulages successives et, par exemple, des opérations de surmoulage permettant d'obtenir des duretés et/ou des textures différentes pour la surface externe des dem i-coques.It should be noted that the one-piece nature of the half-shells does not exclude that they can be manufactured by involving several successive molding steps and, for example, overmolding operations to obtain hardnesses and / or textures different for the outer surface of the demi-hulls.

De même au sens de l'invention, le caractère intégré aux demi-coques des paliers de supports et des nervures signifie que ces derniers ne sont pas rapportés sur les demi-coques après leur fabrication mais font partie intégrante de celles-ci en étant obtenus directement par moulage ou surmoulage.Similarly in the sense of the invention, the character integrated in the half-shells of the support bearings and ribs means that they are not reported on the half-shells after manufacture but are an integral part thereof being obtained directly by molding or overmolding.

Selon une caractéristique de l'invention visant à éviter la dissémination de poils arrachés à l'intérieur du boîtier pour préserver le bon fonctionnement du moteur et du train d'engrenage, la chambre d'épilation est délimitée à l'intérieur du corps par une cloison interposée entre le moteur et la tête d'épilation et constituée par deux demi-cloisons qui sont en contact bord à bord l'une avec l'autre et qui font chacune partie intégrante qu'une demi-coque.According to a feature of the invention to prevent the spread of torn hairs inside the housing to preserve the proper functioning of the motor and the gear train, the depilation chamber is delimited inside the body by a partition interposed between the motor and the depilating head and constituted by two half-partitions which are in edge-to-edge contact with each other and which are each integral part of a half-shell.

Selon une variante de réalisation, chaque demi-cloison est incurvée de manière à suivre la forme de la tête d'épilation. Ceci permet de réduire l'encombrement et le nombre de pièces de l'épilateur.According to an alternative embodiment, each half-wall is curved so as to follow the shape of the epilation head. This reduces the size and number of parts of the epilator.

Selon une caractéristique de l'invention, les demi-coques sont assemblées bord à bord. Ceci permet de réduire l'encombrement et le nombre de pièces de l'épilateur.According to one characteristic of the invention, the half-shells are assembled edge to edge. This reduces the size and number of parts of the epilator.

Selon une autre caractéristique de l'invention la tête d'épilation n'est pas amovible lorsque les demi-coques sont assemblées.According to another characteristic of the invention, the epilation head is not removable when the half-shells are assembled.

Selon une forme de réalisation de l'invention visant à simplifier le montage de l'appareil d'épilation, chaque palier de support d'un pignon du train d'engrenage fait partie intégrante d'une demi-coque et délimite un logement de réception d'un axe de guidage du pignon correspondant, ce logement étant ouvert latéralement en étant situé au-dessus du bord de la demi-coque correspondante de manière à permettre une introduction latérale de l'axe de guidage depuis l'extérieur de la demi-coque avant son assemblage avec l'autre demi-coque.According to one embodiment of the invention for simplifying the assembly of the hair removal apparatus, each support bearing of a pinion of the gear train forms an integral part of a half-shell and delimits a receiving housing. a guide axis of the corresponding pinion, this housing being open laterally being located above the edge of the corresponding half-shell so as to allow lateral introduction of the guide pin from outside the half-shell; hull before its assembly with the other half-hull.

Selon une variante de cette forme de réalisation visant à augmenter la fiabilité de l'appareil d'épilation, l'une et/ou l'autre demi-coque intègre au moins une nervure faisant obstacle à une translation axiale d'un axe de guidage d'un pignon.According to a variant of this embodiment intended to increase the reliability of the hair removal apparatus, the one and / or the other half-shell incorporates at least one rib preventing axial translation of a guide pin. of a pinion.

Toujours dans le sens d'une augmentation de la fiabilité de l'appareil d'épilation, selon une autre variante de cette forme de réalisation, les demi-coques sont conformées pour présenter des surfaces limitant la translation des axes de guidage dans leur logement lorsqu'elles sont assemblées l'une sur l'autre.Still in the sense of increasing the reliability of the hair removal apparatus, according to another variant of this embodiment, the half-shells are shaped to present surfaces limiting the translation of the guide pins in their housing when they are assembled one on the other.

Selon une caractéristique de l'invention visant à simplifier au maximum le système d'entraînement de la tête d'épilation, le train d'engrenage est constitué de deux pignons qui s'engrènent mutuellement et dont un premier pignon engrène directement un pignon porté par l'arbre de sortie du moteur et dont le second pignon engrène directement une roue d'entrainement solidaire de la tête d'épilation.According to a feature of the invention aimed at simplifying as much as possible the drive system of the depilating head, the gear train consists of two mutually meshing gears and a first pinion meshes directly with a pinion carried by the output shaft of the engine and whose second pinion meshes directly a driving wheel secured to the head hair removal.

Selon une variante de cette caractéristique, l'un des deux pignons est un pignon à double étage.According to a variant of this feature, one of the two gears is a double-stage gear.

Selon une autre caractéristique de l'invention visant à simplifier l'assemblage du corps de l'appareil d'épilation, les demi-coques intègrent des crochets de verrouillage et sont accrochées l'une sur l'autre.According to another characteristic of the invention for simplifying the assembly of the body of the hair removal apparatus, the half-shells incorporate locking hooks and are hooked on one another.

Bien entendu les différentes caractéristiques, variantes et formes de réalisation de l'invention peuvent être associées les unes avec les autres selon diverses combinaisons dans la mesure où elles ne sont pas incompatibles ou exclusives les unes des autres.Of course, the various features, variants and embodiments of the invention may be associated with each other in various combinations to the extent that they are not incompatible or exclusive of each other.

Par ailleurs, diverses autres caractéristiques de l'invention ressortent de la description annexée effectuée en référence aux dessins qui illustrent une forme non limitative de réalisation d'un appareil d'épilation électrique conforme à l'invention.Furthermore, various other features of the invention appear from the attached description with reference to the drawings which illustrate a non-limiting embodiment of an electric hair removal apparatus according to the invention.

Exposé détaillé de l'invention :Detailed description of the invention:

Un appareil d'épilation électrique et mécanique selon l'invention, tel qu'illustré à la figure 1, comprend un corps creux, désigné dans son ensemble par la référence 1, qui est constitué de deux demi-coques 2 et 3 formées en monobloc définissant ensemble d'une part, par leur surfaces extérieures une zone de préhension de l'épilateur et, d'autre part, un boîtier de confinement et de maintien des différents éléments fonctionnels constitutifs de l'épilateur.An electric and mechanical depilation apparatus according to the invention, as illustrated in FIG. figure 1 , comprises a hollow body, generally designated by the reference 1, which consists of two half-shells 2 and 3 formed in a single piece defining together on the one hand, by their outer surfaces a gripping area of the epilator and, on the other hand, a box for confinement and maintenance of the various functional elements constituting the epilator.

Ainsi comme le montre la figure 2, les demi-coques 2 et 3 définissent ensemble une chambre d'épilation 4 qui est ouverte au niveau d'une fenêtre 5 délimitée par un bord 6, 7 de chaque demi-coque 2, 3. La fenêtre 5 présente une forme générale arquée dont la forme développée correspond sensiblement à un rectangle. La chambre d'épilation 4 est destinée à recevoir une tête d'épilation 10 non visible à la figure 2 mais représentée à la figure 3.As shown in figure 2 , the half-shells 2 and 3 together define a hair removal chamber 4 which is open at a window 5 delimited by an edge 6, 7 of each half-shell 2, 3. The window 5 has a generally arcuate shape whose developed form corresponds substantially to a rectangle. The epilation chamber 4 is intended to receive an epilation head 10 which is not visible at the figure 2 but represented at figure 3 .

La tête d'épilation 10 présente une forme générale cylindrique et se trouve maintenue sur la demi-coque inférieure 2 par deux paliers 11 et 12 de manière à être mobile en rotation autour d'un axe longitudinal Ω et à affleurer au niveau de la fenêtre 5. Les paliers 11 et 12 font partie intégrante de la demi-coque inférieure 2, c'est-à-dire qu'ils forment un ensemble monobloc avec le reste de la demi-coque 2 et sont obtenus directement lors du moulage de celle-ci.The depilating head 10 has a generally cylindrical shape and is maintained on the lower half-shell 2 by two bearings 11 and 12 so as to be able to rotate about a longitudinal axis Ω and to be flush with the window 5. The bearings 11 and 12 are an integral part of the lower half-shell 2, that is to say they form a one-piece assembly with the rest of the half-shell 2 and are obtained directly during the molding of the -this.

De manière connue en soi, la tête d'épilation 10 comprend une série de pinces 13 qui s'ouvrent et se ferment au fur et à mesure de la rotation de la tête 10. Le mode de réalisation d'une telle tête d'épilation 10 est bien connu de l'homme du métier, notamment en ce qu'il est décrit dans les documents FR 2 926 962 et EP 1 884 174 cités ici à titre de référence, de sorte qu'il n'est pas nécessaire de le décrire ici plus amplement.In a manner known per se, the epilation head 10 comprises a series of clamps 13 which open and close as the head 10 is rotated. The embodiment of such an epilation head 10 is well known to those skilled in the art, in particular in that it is described in the documents FR 2 926 962 and EP 1 884 174 cited here for reference, so there is no need to describe it here in more detail.

La mise en rotation de la tête d'épilation 10 est assurée au moyen d'un moteur électrique 15 maintenu dans la demi-coque inférieure 2 par des nervures 16 qui définissent un berceau d'immobilisation du moteur 15. Les nervures 16 font, comme les paliers 11 et 12, partie intégrante de la demi-coque 2. L'immobilisation du moteur 15 est en outre également assurée par au moins une nervure d'appui 17 offerte par la demi- coque supérieure 3 et faisant partie intégrante de cette dernière.The spinning head 10 is rotated by means of an electric motor 15 held in the lower half-shell 2 by ribs 16 which define a cradle for immobilizing the motor 15. The ribs 16 are, as in FIG. the bearings 11 and 12, an integral part of the half-shell 2. The immobilization of the motor 15 is also ensured by at least one support rib 17 provided by the upper half-shell 3 and forming an integral part thereof.

Afin d'assurer la transmission, à la tête d'épilation 10, du mouvement de rotation du pignon 20 de l'arbre de sortie 21 du moteur 15, il est mis en oeuvre un train d'engrenage 22 référencé en figure 4 et visible aux figures 1 et 3. Selon l'exemple illustré, le train d'engrenage 22 est constitué de deux pignons 23 et 24 dont le premier pignon 23 engrène directement le pignon 20 et le deuxième pignon 24 engrène directement une roue d'entraînement 25 solidaire de la tête d'épilation 10. Il sera remarqué que le premier pignon 23 est un pignon à double étage assurant une démultiplication de la rotation du moteur 15.In order to ensure the transmission, at the depilating head 10, of the rotational movement of the pinion 20 of the output shaft 21 of the motor 15, a gear train 22 referenced in FIG. figure 4 and visible to figures 1 and 3 . According to the illustrated example, the gear train 22 consists of two pinions 23 and 24 whose first pinion 23 directly meshes with the pinion 20 and the second pinion 24 meshes directly with a drive wheel 25 integral with the epilation head 10. It will be noticed that the first pinion 23 is a double-stage pinion ensuring a reduction in the rotation of the motor 15.

Les pignons 23 et 24 sont chacun maintenus par un axe respectivement 27, 28 engagé dans un logement offert par des paliers de support 29,30, 31,32 faisant partie intégrante de la demi-coque inférieure 2. Les paliers de support 29 à 32 sont réalisés de manière que les logements de réception des axes sont ouverts latéralement en étant situés au-dessus du bord de la demi-coque 2, comme le montrent les figures 1 et 4. Ainsi, il est possible de procéder à une introduction latérale de l'axe de guidage 27, 28 depuis l'extérieur de la demi-coque 2, comme indiqué par les flèches F1 de la figure 3, avant assemblage avec l'autre demi-coque 3. Après assemblage, la paroi extérieure de la demi-coque supérieure 3 fait alors, avantageusement, obstacle à la translation axiale des axes 27 et 28 vers l'extérieur. Dans le même sens, la demi-coque inférieure 2 comprend une nervure 35 faisant obstacle, à l'opposé de la paroi de la demi-coque supérieure 3, à la translation de l'axe 28, du deuxième pignon 24, vers l'intérieur. Par ailleurs, le moteur 15 fait obstacle à la translation axiale de l'axe 27, du premier pignon 23, à l'opposé de la paroi de la demi-coque supérieure 3 vers l'intérieur.The pinions 23 and 24 are each held by an axis respectively 27, 28 engaged in a housing provided by support bearings 29,30, 31,32 forming an integral part of the lower half-shell 2. The support bearings 29 to 32 are made in such a way that the reception housings of the axes are open laterally by being situated above the edge of the half-shell 2, as shown by the figures 1 and 4 . Thus, it is possible to proceed to a lateral introduction of the guide axis 27, 28 from the outside of the half-shell 2, as indicated by the arrows F1 of the figure 3 before assembly with the other half-shell 3. After assembly, the outer wall of the upper half-shell 3 then advantageously prevents the axial translation of the axes 27 and 28 outwards. In the same direction, the lower half-shell 2 comprises a rib 35 obstructing, opposite the wall of the upper half-shell 3, the translation of the axis 28, the second pinion 24, to the inside. Furthermore, the motor 15 prevents the axial translation of the axis 27, the first pinion 23, opposite the wall of the upper half-shell 3 inwards.

La demi-coque inférieure 2 intègre également des nervures 34, 35 de support de moyens de pilotage et de raccordement 36 du moteur 15 à une alimentation électrique non représentée.The lower half-shell 2 also incorporates ribs 34, 35 for supporting driving and connecting means 36 of the motor 15 to a not shown power supply.

Afin d'éviter l'accumulation de poils arrachés à l'intérieur du corps 1, ce qui pourrait nuire au fonctionnement du moteur électrique 15 et du train d'engrenage 22, la chambre d'épilation 4 est délimitée à l'intérieur du corps 1 par une cloison 40 interposée entre le moteur 15 et la tête épilation 10. La cloison 40 est constituée par deux demi-cloisons 42 et 43 qui font chacune partie intégrante d'une demi-coque, respectivement inférieure 2 et supérieure 3. Comme le montre la figure 2, les deux demi-cloisons 42 et 43 sont en contact bord à bord l'une avec l'autre lorsque les demi-coques sont assemblées. La cloison 40 est arquée de manière à suivre la forme cylindrique de la tête d'épilation 10.In order to prevent the accumulation of hairs pulled out inside the body 1, which could adversely affect the operation of the electric motor 15 and the gear train 22, the hair removal chamber 4 is delimited inside the body 1 by a partition 40 interposed between the motor 15 and the hair removal head 10. The partition 40 is constituted by two half-walls 42 and 43 which are each an integral part of a half-shell, respectively lower 2 and upper 3. As the show it figure 2 , the two half-walls 42 and 43 are in edge-to-edge contact with each other when the half-shells are assembled. The partition 40 is arched so as to follow the cylindrical shape of the depilating head 10.

Les demi-coques 2 et 3 présentent des formes complémentaires et, selon l'exemple illustré, sensiblement symétriques pour ce qui concerne leur aspect extérieur. Ainsi, les demi-coques 2 et 3 sont conformées de manière à s'assembler bord à bord selon une ligne de joint sensiblement contenue dans un plan sauf pour ce qui concerne deux joues 46 et 47 qui délimitent latéralement la chambre d'épilation 4 et qui sont chacune intégrées à une seule demi-coque respectivement 3 et 2.The half-shells 2 and 3 have complementary shapes and, according to the example shown, substantially symmetrical with respect to their external appearance. Thus, the half-shells 2 and 3 are shaped to join edge to edge along a line of seal substantially contained in a plane except for two cheeks 46 and 47 which laterally delimit the hair removal chamber 4 and which are each integrated to a single half-shell respectively 3 and 2.

Afin de permettre une fixation des demi-coques 2 et 3 l'une sur l'autre sans recourir à des organes de fixation extérieurs, les demi-coques intègrent des crochets de verrouillage 50 destinés à coopérer les uns avec les autres ou avec des fenêtres de verrouillage non visibles aux figures.In order to allow attachment of the half-shells 2 and 3 to one another without the use of external fasteners, the half-shells incorporate locking hooks 50 intended to cooperate with one another or with windows. locking not visible in the figures.

Le procédé de fabrication comprend l'étape d'injection des deux demi-coques Cette étape d'injection peut comprendre par exemple l'injection des deux demi-coques ensemble dans un même outillage, l'avantage étant le gain économique et l'obtention de couleur des deux boitiers d'exactement la même couleur. Ensuite, les engrenages avec leur axe sont mis en place dans une des demi-coques avec le cylindre contenant le mécanisme d'épilation. Puis, la carte électronique et le moteur sont assemblés également dans cette même demi-coque. En dernière étape, l'autre demi-coque vient se clipper sur le premier sous ensemble décrit ci-dessus.The manufacturing process comprises the step of injecting the two half-shells. This injection step can comprise, for example, the injection of the two half-shells together in the same tooling, the advantage being the economic gain and the obtaining color of the two boxes of exactly the same color. Then, the gears with their axis are put in place in one of the half-shells with the cylinder containing the epilation mechanism. Then, the electronic card and the motor are also assembled in this same half-shell. In the last step, the other half-shell is clipped on the first subassembly described above.

Le mode de réalisation, tel que décrit précédemment, permet d'obtenir, avec un nombre de pièces limité notamment pour ce qui concerne le corps et le système de transmission, un appareil d'épilation électrique fiable présentant un coût de fabrication aussi réduit que possible.The embodiment, as described above, makes it possible to obtain, with a limited number of parts, in particular as regards the body and the transmission system, a reliable electrical depilation apparatus having a manufacturing cost as small as possible .

Bien entendu, diverses modifications peuvent être apportées à l'appareil d'épilation électrique selon l'invention dans le cadre des revendications annexées.Of course, various modifications can be made to the electric hair removal apparatus according to the invention within the scope of the appended claims.
