Description

Dispositif de traitement de la chevelure à verrouillage de cartouche  Cartridge lock hair treatment device
du type à libération par poussée  thrust release type
La présente invention concerne les dispositifs de traitement de la chevelure, et plus particulièrement mais non exclusivement ceux destinés à la mise en forme de la chevelure, notamment destinés au lissage, au bouclage ou au gaufrage des cheveux, comportant une recharge en produit cosmétique.  The present invention relates to devices for treating the hair, and more particularly but not exclusively those for shaping the hair, in particular for smoothing, wrapping or embossing the hair, comprising a refill cosmetic product.
L'invention concerne plus particulièrement les dispositifs comportant deux mâchoires mobiles l'une par rapport à l'autre, pouvant prendre une configuration écartée d'introduction d'une mèche de cheveux entre elles et une configuration rapprochée, de traitement de la mèche, les mâchoires étant déplaçables, dans cette configuration rapprochée, le long de la mèche. Les mâchoires portent le plus souvent, dans de tels dispositifs, deux éléments chauffants au contact desquels les cheveux de la mèche sont amenés lors de l'utilisation du dispositif.  The invention relates more particularly to devices comprising two jaws movable relative to each other, which can take a configuration of introduction of a lock of hair between them and a close configuration, treatment of the wick, the jaws being movable, in this configuration close together, along the wick. In such devices, the jaws most often carry two heating elements in contact with which the hair of the wick is brought during the use of the device.
Arrière-plan  Background
De nombreux dispositifs de ce type, parfois encore appelés lisseurs à cheveux ou fers à lisser, ont déjà été proposés.  Many devices of this type, sometimes called hair straighteners or straighteners have already been proposed.
Usuellement, un lisseur à cheveux consiste en deux bras reliés l'un avec l'autre à l'aide d'une charnière, qui permet l'ouverture et la fermeture des bras, et en au moins un élément chauffant disposé sur les bras. Lors des opérations de coiffage d'une mèche de cheveux, cette dernière est introduite entre les deux bras en position ouverte, puis les deux bras sont refermés manuellement sur la mèche de cheveux. La mèche de cheveux est alors soumise, jusqu'à l'ouverture des deux bras et l'extraction de la mèche de cheveux, à la chaleur émise par le ou les éléments chauffants.  Usually, a hair straightener consists of two arms connected to each other by means of a hinge, which allows the opening and closing of the arms, and at least one heating element disposed on the arms. During styling operations of a lock of hair, the latter is introduced between the two arms in the open position, then the two arms are closed manually on the lock of hair. The lock of hair is then subjected, until the opening of the two arms and the extraction of the lock of hair, to the heat emitted by the heating element or elements.
La demande WO 2009/078046 décrit un appareil de coiffage comportant deux bras reliés entre eux pour permettre l'ouverture et la fermeture de l'appareil, au moins un organe chauffant et au moins un siège d'accueil d'un dispositif de traitement capillaire, ce dernier permettant la distribution, en fonctionnement, d'un produit capillaire. Le dispositif de traitement capillaire est composé d'un matériau support imprégné d'un produit capillaire. Le dispositif de traitement capillaire est adapté à une utilisation unique.  WO 2009/078046 discloses a styling apparatus having two arms interconnected to allow the opening and closing of the apparatus, at least one heating member and at least one seat of a capillary treatment device , the latter allowing the distribution, in operation, of a hair product. The hair treatment device is composed of a support material impregnated with a hair product. The hair treatment device is suitable for a single use.
WO 2009/015027 et US 2009/0025247 divulguent un dispositif de lissage des cheveux, permettant l'application d'un produit capillaire par contact avec les cheveux. Le produit capillaire à appliquer est contenu dans une recharge amovible permettant son application. Celle-ci comporte un réservoir contenant le produit capillaire sous forme gélifiée et des orifices de distribution et d'application du produit, réalisés directement au travers d'une paroi du réservoir. La recharge est introduite dans un logement disposé sur l'un des deux bras du lisseur à cheveux, par coulissement. WO 2009/015027 and US 2009/0025247 disclose a device for smoothing the hair, allowing the application of a hair product by contact with the hair. The hair product to be applied is contained in a removable refill allowing its application. This comprises a reservoir containing the capillary product in gelled form and dispensing and application openings of the product, made directly through a wall of the reservoir. The refill is introduced into a housing disposed on one of the two arms of the hair straightener, by sliding.
II est connu également de la demande WO 2013/045331 un applicateur pour l'application d'une substance de soin aux cheveux, comportant une cartouche de substance de soin reçue dans un logement de P applicateur. La cartouche comporte un support poreux imbibé de la substance de soin.  It is also known from the application WO 2013/045331 an applicator for the application of a hair care substance, comprising a cartridge of care substance received in a housing applicator P. The cartridge has a porous support soaked with the care substance.
La demande WO 2013/090896 concerne un appareil de traitement des cheveux, notamment de coiffage, munie d'une cartouche d' agent de traitement pouvant être démontée. La cartouche d'agent de traitement comporte essentiellement un support d'agent de traitement, notamment un matériau poreux imbibé, à appliquer sur les cheveux ou la peau, fixé à un accessoire formant support mécanique et languette de saisie. La cartouche est montée dans un logement de l'appareil de traitement des cheveux, logement de section complémentaire à la section de la cartouche d'agent de traitement.  The application WO 2013/090896 relates to a hair treatment apparatus, especially styling, provided with a treatment agent cartridge that can be disassembled. The treatment agent cartridge essentially comprises a treatment agent carrier, in particular a porous impregnated material, to be applied to the hair or the skin, attached to an accessory forming a mechanical support and grasping tab. The cartridge is mounted in a housing of the hair treatment apparatus, housing of complementary section to the section of the treatment agent cartridge.
Selon un mode de réalisation décrit dans la demande WO 2013/090896, l'accessoire prend la forme d'une aiguille traversant le support d'agent de traitement cylindrique. L'aiguille présente, à son extrémité opposée à la languette de saisie, un ergot de verrouillage, s'étendant radialement, destiné à coopérer avec un logement de verrouillage, complémentaire, formé dans l'appareil de traitement des cheveux. Le logement de verrouillage présente une portion de passage de l'ergot de verrouillage et une portion de blocage de l'ergot de verrouillage dans la direction longitudinale de l'accessoire en forme d'aiguille, dans le sens d'un retrait de la cartouche, cette portion de blocage étant accessible par l'ergot de verrouillage, depuis la portion de passage, par rotation de la cartouche autour de l'axe de l'accessoire en forme d'aiguille. La cartouche est ainsi fixée dans l'appareil au moyen d'un système de verrouillage du type à baïonnette.  According to an embodiment described in the application WO 2013/090896, the accessory takes the form of a needle passing through the cylindrical treatment agent support. The needle has, at its end opposite the gripping tongue, a radially extending locking lug for cooperating with a complementary locking housing formed in the hair treatment apparatus. The locking housing has a passage portion of the locking lug and a locking portion of the locking lug in the longitudinal direction of the needle-shaped accessory in the direction of removal of the cartridge. , this blocking portion being accessible by the locking pin, from the passage portion, by rotation of the cartridge around the axis of the needle-shaped accessory. The cartridge is thus fixed in the apparatus by means of a bayonet type locking system.
Ce dernier système de verrouillage du type à baïonnette permet un montage/démontage rapide de la cartouche d'agent de traitement sur l'appareil. Cependant, il nécessite d'avoir une cartouche et un logement présentant une section circulaire. Cette section circulaire n'apparait pas optimale pour délivrer l'agent de traitement et l'appliquer aux cheveux. Il existe donc un besoin pour perfectionner encore les dispositifs permettant l'application d'un produit capillaire afin de permettre à l'utilisateur de pouvoir aisément recharger le dispositif en produit capillaire et/ou changer de produit capillaire à appliquer. The latter bayonet type locking system allows quick mounting / disassembly of the treatment agent cartridge on the device. However, it requires having a cartridge and a housing having a circular section. This circular section does not appear optimal for delivering the treatment agent and applying it to the hair. There is therefore a need to further improve the devices the application of a hair product to allow the user to easily reload the device into a hair product and / or change the hair product to be applied.

Dans la suite de la description, les éléments identiques ou de fonctions identiques portent le même signe de référence. À fin de concision de la présente description, ils ne sont pas décrits en regard de chacune des figures, seules les différences entre les différents exemples étant décrites.  In the remainder of the description, identical elements or identical functions bear the same reference sign. For brevity of the present description, they are not described with respect to each of the figures, only the differences between the various examples being described.
Une pièce à main 10 d'un exemple de dispositif de traitement de la chevelure est représentée sur les figures 1 et 2. Le dispositif de traitement de la chevelure illustré est par exemple un lisseur avec éléments chauffants plats, notamment venant en contact en position fermée.  A handpiece 10 of an example of a device for treating the hair is represented in FIGS. 1 and 2. The hair treatment device illustrated is for example a straightener with flat heating elements, in particular coming into contact in the closed position. .
La pièce à main 10 présente deux mâchoires 12 et 14 mobiles l'une par rapport à l'autre, entre une configuration écartée (non représentée), d'introduction entre elles d'une mèche de cheveux, et une configuration rapprochée, de traitement de la mèche de cheveux.  The handpiece 10 has two jaws 12 and 14 movable relative to each other, between a remote configuration (not shown), introduction between them of a lock of hair, and a close configuration of treatment the lock of hair.
Les mâchoires 12, 14 sont portées par des bras respectifs inférieur 16 et supérieur 18. Les bras inférieur 16 et supérieur 18 sont, dans l'exemple considéré, articulés l'un par rapport à l'autre au moyen d'un axe d'articulation 20, la pièce à main 10 formant ainsi une pince.  The jaws 12, 14 are carried by respective lower arms 16 and upper 18. The lower arm 16 and upper arm 18 are, in the example in question, articulated with respect to each other by means of an axis of articulation 20, the handpiece 10 thus forming a clamp.
Les bras inférieur 16 et supérieur 18 ont ici, chacun, une longueur totale comprise entre 22 cm et 37 cm, notamment 31 cm. Les bras inférieur 16 et supérieur 18 définissent, entre l'axe d'articulation 20 et les mâchoires 12, 14, des demi-poignées respectives 22, 24, sur lesquelles l'utilisateur peut appuyer pour rapprocher les mâchoires 12, 14, l'une de l'autre.  Lower arm 16 and upper 18 here each have a total length of between 22 cm and 37 cm, in particular 31 cm. The lower arm 16 and upper arm 18 define, between the hinge pin 20 and the jaws 12, 14, respective half-handles 22, 24, on which the user can press to bring the jaws 12, 14, the one of the other.
Un organe de rappel élastique (non apparent) peut être prévu pour rappeler les mâchoires 12, 14 en configuration écartée. Cet organe de rappel élastique peut par exemple prendre la forme d'un ressort disposé autour de l'axe d'articulation 20 des bras inférieur 16 et supérieur 18. An elastic return member (not apparent) may be provided to return the jaws 12, 14 in the separated configuration. This elastic return member may for example take the form of a spring disposed around the axis of articulation 20 of the lower arm 16 and upper 18.
Bien entendu, les mâchoires 12, 14 peuvent être rendues mobiles l'une par rapport à l'autre autrement. Elles peuvent notamment être mobiles entre elles non pas par rotation, comme c'est le cas avec une articulation, mais par translation. Toutefois, l'ergonomie offerte par une articulation est préférée.  Of course, the jaws 12, 14 may be made movable relative to each other otherwise. They may in particular be movable between them not by rotation, as is the case with a joint, but by translation. However, the ergonomics offered by a joint is preferred.
Les mâchoires 12, 14 définissent entre elles une zone de traitement de la chevelure, destinée à recevoir une mèche de cheveux à traiter, le long de laquelle la pièce à main 10 est déplacée durant le traitement. Le déplacement de la pièce à main est par exemple effectué dans le sens allant de la racine vers la pointe des cheveux de la mèche.  The jaws 12, 14 define between them a treatment area of the hair, intended to receive a lock of hair to be treated, along which the handpiece 10 is moved during the treatment. The movement of the handpiece is for example made in the direction from the root to the tip of the hair of the wick.
Dans l'exemple des figures 1 et 2, la pièce à main 10 permet d'appliquer un produit cosmétique, d'assurer un traitement de la chevelure par de la vapeur, puis d'effectuer un traitement thermique des cheveux par contact avec deux surfaces chaudes 26, 28, portées respectivement par chacune des mâchoires 12, 14.  In the example of FIGS. 1 and 2, the handpiece 10 makes it possible to apply a cosmetic product, to treat the hair with steam, and then to heat treat the hair by contact with two surfaces. 26, 28, carried respectively by each of the jaws 12, 14.
La direction D de déplacement de la pièce à main 10 sur les cheveux, illustrée sur la figure 1, est de préférence sensiblement perpendiculaire à l'axe médian des bras inférieur 16 et supérieur 18, c'est-à-dire sensiblement parallèle à l'axe d'articulation 20.  The direction D of displacement of the handpiece 10 on the hair, illustrated in Figure 1, is preferably substantially perpendicular to the median axis of the lower arm 16 and upper 18, that is to say substantially parallel to the hinge pin 20.
Dans l'exemple illustre, la pièce à main 10 est reliée par un cordon 30 à une station de base non représentée, fixe durant le traitement et elle-même reliée au secteur. Cette station de base assure l'alimentation électrique de la pièce à main 10 ainsi que son alimentation en eau en vue de la génération de vapeur. La station de base peut également réaliser des fonctions annexes de traitement de signaux électriques reçus de la pièce à main 10. Le cordon 30 qui relie la pièce à main 10 à la station de base peut ainsi comporter divers conducteurs électriques et un tuyau d'alimentation en eau.  In the example shown, the handpiece 10 is connected by a cord 30 to a base station not shown, fixed during the treatment and itself connected to the sector. This base station provides power to the handpiece 10 and its water supply for steam generation. The base station may also perform ancillary functions for processing electrical signals received from the handpiece 10. The cord 30 which connects the handpiece 10 to the base station may thus comprise various electrical conductors and a supply pipe in water.
Une interface utilisateur, non représentée sur les figures, peut également être présente sur la pièce à main 10, par exemple pour permettre à l'utilisateur de mettre en marche ou non certains composants de celle-ci.  A user interface, not shown in the figures, may also be present on the handpiece 10, for example to allow the user to start or not certain components thereof.
L'application du produit cosmétique est assurée par une recharge 32 portée par l'un des deux bras 16, 18, ici, le bras supérieur 18 qui vient au contact d'un élément presseur 34. L'élément presseur 34 est reçu dans un logement formé ici dans le bras inférieur 16, de manière amovible. L'élément presseur est ici mobile dans son logement. La recharge 32 est reçue dans un logement formé dans le bras supérieur 18, de forme allongée dans la direction d'insertion de la recharge. The application of the cosmetic product is provided by a refill 32 carried by one of the two arms 16, 18, here, the upper arm 18 which comes into contact with a pressing element 34. The pressing element 34 is received in a housing formed here in the lower arm 16, removably. The pressing element is here mobile in its housing. The recharge 32 is received in a housing formed in the upper arm 18, elongated in the direction of insertion of the refill.
Le bras opposé à celui sur lequel la recharge 32 est disposée peut présenter une sortie de vapeur, et de préférence également un peigne. De préférence, notamment lorsque l'on cherche à lisser les cheveux, le dispositif comporte un élément chauffant destiné à venir au contact des cheveux, ou, mieux, deux éléments chauffants disposés chacun sur un bras. Ce ou ces éléments chauffants peuvent comporter chacun une plaque en un matériau bon conducteur de la chaleur, définissant une surface chaude de contact avec les cheveux, dont la température est par exemple supérieure ou égale à 95°C, mieux comprise entre 90 et 230°C. De préférence encore, l'application de produit sur la mèche de cheveux introduite dans le dispositif se fait avant l'application de vapeur et/ou lissage par le ou les éléments chauffants et après le peignage. Ainsi, les cheveux introduits entre les bras peuvent venir en contact avec l'organe d'application avant d'être exposés à la vapeur et aux éléments chauffants lors du déplacement de la mèche entre les bras du dispositif.  The opposite arm to that on which the refill 32 is disposed may have a steam outlet, and preferably also a comb. Preferably, especially when one seeks to smooth the hair, the device comprises a heating element intended to come into contact with the hair, or, better, two heating elements each arranged on an arm. This or these heating elements may each comprise a plate of a good heat-conducting material, defining a hot surface of contact with the hair, whose temperature is for example greater than or equal to 95 ° C, better between 90 and 230 ° vs. More preferably, the application of product on the lock of hair introduced into the device is done before the application of steam and / or smoothing by the heating element (s) and after combing. Thus, the hair introduced between the arms can come into contact with the applicator member before being exposed to the steam and the heating elements during movement of the wick between the arms of the device.
La recharge 32 (ou cartouche) comporte un corps 36 et un organe d'application The refill 32 (or cartridge) comprises a body 36 and an application member
38 reçu dans le corps de telle sorte que, lorsque la recharge 32 est fixée à l'appareil, l'organe d'application 38 est apte à venir au contact des cheveux s'étendant à travers la zone de traitement. 38, when the refill 32 is attached to the apparatus, the applicator member 38 is adapted to contact the hair extending through the treatment zone.
Le corps 36 présente un renfoncement 44 s 'ouvrant vers l'extérieur par une ouverture 46 recevant l'organe d'application 38. Plus précisément, l'organe d'application fait saillie hors du renfoncement 44 pour pouvoir être en contact avec une mèche de cheveux à traiter.  The body 36 has a recess 44 s' opening outwards through an opening 46 receiving the applicator member 38. More specifically, the applicator member protrudes out of the recess 44 to be in contact with a wick hair to treat.
Le corps 36 de la recharge 32 peut comporter des reliefs d'accrochage 48 saillant dans le renfoncement 44, qui assurent le maintien en position de l'organe d'application 38 dans le renfoncement 44, même durant l'application du produit cosmétique sur la mèche de cheveux.  The body 36 of the refill 32 may comprise hooking protrusions 48 protruding into the recess 44, which ensure the position of the applicator member 38 in the recess 44, even during the application of the cosmetic product on the lock of hair.
Les reliefs d'accrochage 48 peuvent être moulés avec le corps 36. Le corps 36 et les reliefs d'accrochage 48 peuvent notamment être en matière thermoplastique, notamment en polytéréphtalate de butylène (PBT), en polytéréphtalate d'éthylène (PET), en polyamide (PA), en élastomère ou en leur mélange, en particulier en un mélange de PBT et PET. L'organe d'application est par exemple en un matériau poreux, notamment en fibres synthétiques ou naturelles orientées toutes sensiblement dans la même direction et moulées pour former un feutre. L'organe d'application est imprégné de produit. The hooking reliefs 48 may be molded with the body 36. The body 36 and the attachment reliefs 48 may in particular be made of thermoplastic material, in particular polybutylene terephthalate (PBT), polyethylene terephthalate (PET), polyamide (PA), of elastomer or of their mixture, in particular of a mixture of PBT and PET. The applicator member is for example a porous material, especially synthetic or natural fibers all oriented substantially in the same direction and molded to form a felt. The application member is impregnated with product.
La recharge 32 peut être reliée à l'un quelconque des bras inférieur 16 ou supérieur 18 (ici le bras supérieur 18). La recharge 32 est reliée au bras 18 qui la reçoit dans un logement prévu à cet effet, par tout moyen. Notamment, comme illustré sur la figure 2, la recharge 32 est reçue par coulissement, selon une direction d'insertion de la recharge dans son logement, d'une nervure 40 du corps 36 dans une rainure 42 de section complémentaire, formée dans le bras 18. Cette liaison permet d'assurer une position relative de la recharge 32 par rapport au bras 18, notamment par rapport à la direction D de déplacement de la pièce à main 10. En variante, la nervure peut être formée sur le bras 18 et la rainure sur le corps 36.  The refill 32 may be connected to any of the lower arm 16 or upper 18 (here the upper arm 18). The refill 32 is connected to the arm 18 which receives it in a housing provided for this purpose, by any means. In particular, as illustrated in FIG. 2, the refill 32 is slidably received, according to a direction of insertion of the refill into its housing, of a rib 40 of the body 36 in a groove 42 of complementary section, formed in the arm 18. This connection makes it possible to ensure a relative position of the refill 32 with respect to the arm 18, in particular with respect to the direction D of displacement of the handpiece 10. In a variant, the rib can be formed on the arm 18 and the groove on the body 36.
Pour verrouiller la liaison de la recharge 32 et du bras 18, la recharge 32 est ici munie d'une partie mâle 50 d'un dispositif de verrouillage du type à libération par poussée (ou « push-push »), le bras 18 étant muni d'une partie femelle 52 correspondante d'un dispositif de verrouillage du type à libération par poussée.  To lock the connection of the refill 32 and the arm 18, the refill 32 is here provided with a male part 50 of a push-push type locking device (the push-push), the arm 18 being provided with a corresponding female part 52 of a push release type locking device.
Par dispositif de verrouillage de type « push-push » ou dispositif de verrouillage à libération par poussée, on entend un système permettant :  By "push-push" type locking device or thrust release locking device is meant a system allowing:
un verrouillage d'un élément mâle par rapport à un élément femelle par une simple translation relative de l'élément mâle par rapport à l'élément femelle dans une direction et selon un sens, et  locking a male element relative to a female element by a simple relative translation of the male element relative to the female element in one direction and in one direction, and
un déverrouillage de l'élément mâle par rapport à l'élément femelle par translation relative de l'élément mâle par rapport à l'élément femelle, dans la même direction et dans le même sens.  unlocking the male element relative to the female element by relative translation of the male element relative to the female element, in the same direction and in the same direction.
Par exemple, l'élément mâle peut être verrouillé et déverrouillé par pression sur celui-ci dans une direction et dans un sens dirigés vers l'élément femelle.  For example, the male member may be locked and unlocked by pressure thereon in a direction and in a direction directed toward the female member.
De préférence, le verrouillage et le déverrouillage consiste en une poussée sur l'élément mâle dans une même direction et dans un même sens, à l'exclusion de toute autre manipulation ou tout autre mouvement relatif de l'élément mâle par rapport à l'élément femelle.  Preferably, the locking and unlocking is a thrust on the male element in the same direction and in the same direction, excluding any other manipulation or other relative movement of the male element relative to the female element.
Par verrouillage d'un élément mâle par rapport à un élément femelle, on entend qu'un mouvement relatif de l'élément mâle par rapport à l'élément femelle est impossible, ou tout du moins empêché par le système de verrouillage. Un tel système peut être utilisé seul, pour relier la recharge au bras. Cependant, pour assurer une meilleure stabilité de la liaison de la recharge sur le bras, un dispositif de liaison est mis en œuvre en plus du dispositif de verrouillage (ici la coopération de la nervure 40 et de la rainure 42). By locking a male element with respect to a female element, it is meant that a relative movement of the male element relative to the female element is impossible, or at least prevented by the locking system. Such a system can be used alone, to connect the refill to the arm. However, to ensure a better stability of the connection of the refill on the arm, a connecting device is implemented in addition to the locking device (here the cooperation of the rib 40 and the groove 42).
Un tel dispositif de verrouillage « push-push » procure une grande facilité de verrouillage et de déverrouillage de la liaison de la recharge 32 sur la pièce à main 10 par rapport aux dispositifs connus des documents de l'art antérieur.  Such a "push-push" locking device provides a great ease of locking and unlocking the connection of the refill 32 on the handpiece 10 with respect to the known devices of the documents of the prior art.
Un premier exemple de dispositif de verrouillage de type « push-push » est illustré aux figures 3 et 4, respectivement en position déverrouillée et en position verrouillée.  A first example of a "push-push" type locking device is illustrated in FIGS. 3 and 4, respectively in the unlocked position and in the locked position.
Dans le cas illustré sur ces figures, l'élément mâle 50 du dispositif de verrouillage de type « push-push » consiste essentiellement en une saillie 54, disposée à une extrémité de la recharge 32 et s'étendant sensiblement selon la direction d'insertion de la recharge 32 dans le bras 18. La saillie 54 présente ici une section en forme d'ogive présentant des bourrelets 56 symétriques (ou section en forme de tête de champignon). Les bourrelets 56 forment une surépaisseur dans une direction perpendiculaire à la direction d'insertion de la recharge dans son logement.  In the case illustrated in these figures, the male element 50 of the "push-push" type locking device consists essentially of a projection 54, disposed at one end of the refill 32 and extending substantially in the direction of insertion. of the refill 32 in the arm 18. The projection 54 here has a section in the form of ogive having symmetrical beads 56 (or mushroom head section). The beads 56 form an extra thickness in a direction perpendicular to the insertion direction of the refill in its housing.
L'élément femelle 52, solidaire du bras 18 comporte lui un élément 58 de réception de la saillie 54 (ou coulisseau de réception ou siège). Cet élément de réception 58 comprend ici deux bras symétriques 60 souples, c'est-à-dire aptes à se déformer. Ces bras symétriques 60 présentent également, au voisinage de leur extrémité libre respective, un bourrelet 62. Ce bourrelet 62 forme aussi une surépaisseur dans une direction perpendiculaire à la direction d'insertion de la recharge dans le logement, dans la position de verrouillage de la liaison de la recharge au bras, cette surépaisseur étant dirigée vers la saillie 54 de l'élément mâle. Cet élément de réception 58 est monté contraint élastiquement par rapport à un bâti 64 fixé au bras 18 ou formé directement dans ce bras 18. Ce bâti 64 forme une cavité 66 destinée notamment à recevoir au moins partiellement l'élément de réception 58 et une partie de la saillie 54 de l'élément mâle. Cette cavité 66 est ici de forme sensiblement parallélépipédique rectangle avec un épaulement 68.  The female element 52, integral with the arm 18, has an element 58 for receiving the projection 54 (or receiving slide or seat). This receiving element 58 here comprises two symmetrical arms 60 flexible, that is to say able to deform. These symmetrical arms 60 also have, in the vicinity of their respective free ends, a bead 62. This bead 62 also forms an extra thickness in a direction perpendicular to the insertion direction of the refill in the housing, in the locking position of the binding of the refill to the arm, this extra thickness being directed towards the projection 54 of the male element. This receiving element 58 is mounted elastically constrained relative to a frame 64 fixed to the arm 18 or formed directly in this arm 18. This frame 64 forms a cavity 66 intended in particular to receive at least partially the receiving element 58 and a part protrusion 54 of the male element. This cavity 66 is here of substantially rectangular parallelepipedal shape with a shoulder 68.
L'élément de réception 58 est monté contraint dans la cavité 66 au moyen d'un ressort 70, reçu dans la cavité 66. Le ressort 70 tend à faire sortir l'élément de réception 58 hors de la cavité 66. La position sortie de l'élément de réception 58 peut être définie par une butée de l'élément de réception sur une paroi de la cavité 66. L'élément de réception 58 comprend par ailleurs un ergot 72 (visible sur la figure 4) apte à venir en butée, sous l'effet du ressort 70 et dans la position verrouillé du dispositif du type « push-push », dans une rainure 74 creusée dans une paroi du bâti 64. La rainure 74 s'étend de préférence sensiblement selon la direction d'insertion de la recharge dans le logement. The receiving element 58 is mounted constrained in the cavity 66 by means of a spring 70, received in the cavity 66. The spring 70 tends to push the receiving element 58 out of the cavity 66. the receiving element 58 may be defined by a stop of the receiving element on a wall of the cavity 66. The receiving element 58 further comprises a lug 72 (visible in FIG. 4) able to come into abutment, under the effect of the spring 70 and in the locked position of the device of the "push-push" type, in a groove 74 groove 74 in a wall of the frame 64. The groove 74 preferably extends substantially in the direction of insertion of the refill in the housing.
Le fonctionnement de ce dispositif de verrouillage du type « push-push » est le suivant.  The operation of this "push-push" type locking device is as follows.
On introduit la saillie 54 de l'élément mâle du dispositif de verrouillage dans l'élément de réception 58, c'est-à-dire entre les deux bras symétriques 60 de cet élément de réception 58, par translation selon la direction d'insertion T. On continue à pousser dans la direction d'insertion T, de sorte que les bras 60 de l'élément de réception se replient au contact du bord de la cavité 66 formé par le bâti 64. Ce faisant, les bourrelets 62 des bras de l'élément de réception 58 se positionnent derrière - par rapport à la direction d'insertion T - les bourrelets 56 de la saillie 54 de l'élément mâle. Le repli des bras 60 de l'élément de réception permet ainsi un meilleur guidage de la saillie 54 et donc de l'élément mâle 50 par rapport à l'élément femelle 52. Il est à noter ici que cette poussée sur l'élément mâle 50 est réalisée à Γ encontre de la force de rappel du ressort 70.  The protrusion 54 of the male element of the locking device is introduced into the receiving element 58, that is to say between the two symmetrical arms 60 of this receiving element 58, by translation along the direction of insertion. T. Continue pushing in the direction of insertion T, so that the arms 60 of the receiving element fold back in contact with the edge of the cavity 66 formed by the frame 64. In doing so, the beads 62 of the arms of the receiving element 58 are positioned behind - with respect to the direction of insertion T - the beads 56 of the projection 54 of the male element. The folding of the arms 60 of the receiving element thus allows better guidance of the projection 54 and therefore of the male element 50 with respect to the female element 52. It should be noted here that this thrust on the male element 50 is made against the restoring force of the spring 70.
On continue ensuite à pousser sur l'élément mâle 50, jusqu'à ce que l'ergot 72 de l'élément de réception 58 soit entièrement reçu dans la rainure 74. On relâche alors l'élément mâle. Celui-ci est maintenu en place du fait que le ressort 70 contraint l'ergot 72 en butée contre le fond 76 de la rainure 74 (fond par rapport à la direction d'insertion T) et que dans cette position, les bras 60 de l'élément de réception 58 sont repliés et emprisonnent la saillie 54. Notamment les bourrelets 62 des bras 60 de l'élément de réception 58 sont en butée contre les bourrelets 56 de la saillie 54 dans la direction d'insertion T de la recharge dans le logement.  It then continues to push on the male element 50, until the lug 72 of the receiving element 58 is fully received in the groove 74. Then releases the male element. This is held in place because the spring 70 constrains the lug 72 in abutment against the bottom 76 of the groove 74 (bottom relative to the direction of insertion T) and that in this position, the arms 60 of the receiving element 58 is folded and traps the projection 54. In particular the beads 62 of the arms 60 of the receiving member 58 abut against the beads 56 of the projection 54 in the direction of insertion T of the refill in housing.
Pour déverrouiller l'élément mâle 50 par rapport à l'élément femelle 52, on pousse de nouveau sur l'élément mâle 50 dans la direction d'insertion, et dans le même sens, par exemple jusqu'à ce que les bras 60 de l'élément de réception 58 viennent en butée contre l'épaulement formé par le bâti délimitant la cavité 66. Le ressort 70 peut alors être chargé de manière suffisante pour vaincre la butée susceptible d'être formée par le contact de l'ergot 72 contre le fond 76 de la rainure 74. En relâchant l'élément mâle 50, le ressort 70 exerce alors un effort de poussée de l'élément de réception 58 tel que l'ergot 72 est déformé au contact du fond de la rainure 74 et ne permet pas de former une butée. L'élément de réception est déplacé dans la direction d'insertion T, mais dans le sens opposé, de sorte que les bras 60 de l'élément de réception 58 sont libérés et se déploient de nouveau, libérant ainsi la saillie 54 de l'élément mâle 50. To unlock the male element 50 with respect to the female element 52, the male element 50 is pushed again in the direction of insertion, and in the same direction, for example until the arms 60 of the the receiving element 58 abuts against the shoulder formed by the frame delimiting the cavity 66. The spring 70 can then be loaded sufficiently to overcome the stop that can be formed by the contact of the lug 72 against the bottom 76 of the groove 74. By releasing the male element 50, the spring 70 then exerts a thrust force of the receiving member 58 such that the lug 72 is deformed at the contact the bottom of the groove 74 and does not form a stop. The receiving member is moved in the insertion direction T, but in the opposite direction, so that the arms 60 of the receiving member 58 are released and unfold again, thereby releasing the projection 54 from the male element 50.
En variante à ce dispositif de verrouillage de type « push-push », le ressort 70 ou tout autre élément élastique mise en œuvre pour contraindre élastiquement l'élément de réception, peut être à mémoire de forme. Notamment, le ressort 70 peut présenter deux positions distinctes :  As an alternative to this "push-push" type locking device, the spring 70 or any other elastic element implemented to elastically constrain the receiving element may be of shape memory. In particular, the spring 70 can have two distinct positions:
l'une, comprimée, correspondant à la position de verrouillage de la liaison de la recharge au bras, et  one, compressed, corresponding to the locking position of the connection of the refill to the arm, and
l'autre, détendue, correspondant à la position de libération de la liaison de la recharge au bras.  the other, relaxed, corresponding to the release position of the connection of the refill to the arm.
Dans ce cas, l'élément de réception 58 peut ne pas former de butée destinée à coopérer avec le fond d'une rainure formée dans un bâti fixe. Le ressort 70 peut passer d'une position à l'autre par simple poussée dans la direction d'insertion de la recharge dans le logement. Le verrouillage de la liaison est réalisé du fait que le ressort a une forme fixe dans laquelle la saillie est piégée dans l'élément de réception. Notamment, la coopération des bourrelets des bras de l'élément de réception et de la saillie empêche celle-ci d'être retirée de l'élément de réception.  In this case, the receiving member 58 may not form a stop for cooperating with the bottom of a groove formed in a fixed frame. The spring 70 can move from one position to another by simply pushing in the insertion direction of the refill in the housing. The locking of the connection is realized because the spring has a fixed shape in which the projection is trapped in the receiving element. In particular, the cooperation of the beads of the arms of the receiving member and the projection prevents it from being removed from the receiving element.
Les figures 5 et 6a-6e illustrent un autre dispositif de verrouillage du type « push- push » pouvant être mis en œuvre pour verrouiller une recharge sur une pièce à main.  Figures 5 and 6a-6e illustrate another "push-push" type locking device that can be implemented to lock a refill on a handpiece.
Dans ce dispositif de verrouillage du type « push-push », l'élément de réception peut ne pas comporter d'ergot destiné à venir en butée contre le fond d'une rainure dans le bâti. Ici, en effet, la butée est réalisée au niveau d'un pion (ou suiveur) 76 solidaire du bras de la pièce à main et reçu dans un chemin 78 formé sur le corps de la recharge (éventuellement sur une surface de la nervure 40).  In this "push-push" type locking device, the receiving element may not include a lug intended to abut against the bottom of a groove in the frame. Here, in fact, the stop is made at a pin (or follower) 76 secured to the arm of the handpiece and received in a path 78 formed on the body of the refill (possibly on a surface of the rib 40 ).
Le pion 76 est réalisé au moyen d'une pièce en forme de « Z » montée libre en rotation au niveau d'une de ses extrémités sur le bras de la pièce à main 10. L'extrémité opposée de cette pièce en forme de « Z » (ou extrémité libre) est destinée à être reçue dans le chemin 78 réalisé sur la recharge et visible sur les figures 6a-6e, lors de l'insertion de la recharge dans le logement formé dans le bras. La forme de ce chemin est décrite ci-après en regard des figures 6a-6e qui illustrent le verrouillage et le déverrouillage de la liaison de la recharge au bras. The pin 76 is made by means of a "Z" -shaped piece rotatably mounted at one of its ends on the arm of the handpiece 10. The opposite end of this piece in the shape of " Z "(or free end) is intended to be received in the path 78 made on the refill and visible in Figures 6a-6e, during the insertion of the refill in the housing formed in the arm. The shape of this path is described below in FIGS. 6a-6e illustrate the locking and unlocking of the connection of the refill to the arm.
Tout d'abord, le chemin 78 comporte un premier tronçon 781 s'étendant parallèlement à direction d'insertion T de la recharge dans le logement. Ce tronçon permet de guider l'insertion de la recharge (figure 6a) depuis une extrémité du chemin 78 permettant au pion 76 de pénétrer dans ce chemin 78.  First, the path 78 includes a first section 781 extending parallel to the insertion direction T of the refill in the housing. This section makes it possible to guide the insertion of the refill (FIG. 6a) from one end of the path 78 allowing the pin 76 to enter this path 78.
Ce premier tronçon 781 débouche dans un coude 782 (figure 6b), qui permet d'indiquer à l'utilisateur qui insère la recharge dans le logement qu'il est arrivé à la position souhaitée de la recharge. Ce coude 782 forme en effet une butée contre l'insertion de la recharge au-delà de son logement, facilement reconnaissable par l'utilisateur, puisque le pion 76 est en butée contre le coude, comme représenté en pointillé sur les figures 6b et 6c.  This first section 781 opens into an elbow 782 (Figure 6b), which indicates to the user who inserts the recharge in the housing that he arrived at the desired position of the refill. This elbow 782 forms a stop against the insertion of the refill beyond its housing, easily recognizable by the user, since the pin 76 abuts against the elbow, as shown in dotted lines in FIGS. 6b and 6c. .
L'utilisateur relâche alors la pression sur le corps de recharge. Le ressort 70 repousse alors légèrement la recharge 32, ce qui permet au pion 76 de suivre le coude 782 jusqu'à une encoche 783 (figure 6c) formant butée pour le pion 76 dans la direction d'insertion de la recharge dans le logement, contre l'action du ressort 70. Dans cette position du pion 76 reçu dans l'encoche 783, la liaison de la recharge 32 au bras est verrouillée.  The user then releases the pressure on the charging body. The spring 70 then slightly pushes the refill 32, which allows the pin 76 to follow the elbow 782 to a notch 783 (Figure 6c) forming a stop for the pin 76 in the insertion direction of the refill in the housing, against the action of the spring 70. In this position of the pin 76 received in the notch 783, the connection of the refill 32 to the arm is locked.
L'utilisateur pousse alors de nouveau sur la recharge dans la direction et le sens d'insertion de la recharge. Il fait ainsi sortir le pion 76 de l'encoche 783, le pion 76 entrant alors en contact avec une rampe 784 du chemin 78 (figure 6d). Cette rampe 784 permet de guider le pion 76 hors de l'encoche 783 et hors du premier tronçon 781, vers un second tronçon 785 parallèle au premier tronçon 781 (figure 6e). Pour ce faire, la rampe 784 s'étend en vis-à-vis de l'encoche 783, dans la direction d'insertion de la cartouche dans le logement.  The user then pushes again on the refill in the direction and direction of insertion of the refill. It thus leaves the pin 76 of the notch 783, the pin 76 then coming into contact with a ramp 784 of the path 78 (Figure 6d). This ramp 784 serves to guide the pin 76 out of the notch 783 and out of the first section 781, to a second section 785 parallel to the first section 781 (Figure 6e). To do this, the ramp 784 extends vis-à-vis the notch 783, in the direction of insertion of the cartridge into the housing.
En relâchant alors la pression sur la recharge 32, l'utilisateur permet au ressort 70 de pousser sur la recharge 32. Dans ce cas, le pion 76 suit le second tronçon 785, jusqu'à une deuxième extrémité du chemin 78 permettant la libération du pion 76 et, ainsi, la libération du verrouillage de la liaison de la recharge au bras.  By then releasing the pressure on the refill 32, the user allows the spring 70 to push on the refill 32. In this case, the pin 76 follows the second section 785, to a second end of the path 78 allowing the release of the pion 76 and, thus, the release of the locking of the connection of the refill to the arm.
Selon encore un autre exemple, non illustré, le corps de recharge présente une partie à symétrie de révolution, libre en rotation autour d'un axe parallèle à la direction d'insertion de la recharge dans son logement. Cette partie à symétrie de révolution peut notamment être cylindrique, tubulaire, conique ou tronconique. Cette partie forme une rampe, par exemple une rampe hélicoïdale, et une butée. La butée s'étend de préférence sur une section angulaire limitée de la partie à symétrie de révolution. Le bras comprend lui une griffe, destinée à coopérer avec la rampe, et une butée complémentaire de la butée formée sur le corps de recharge. Ainsi, au cours de l'insertion de la recharge dans le logement, la coopération de la griffe et de la rampe guide la butée de la recharge en regard de la butée complémentaire formée sur le bras de telle sorte que la butée et la butée complémentaire soient en contact sous l'effet du corps élastique dans la position de verrouillage de la liaison de la recharge et du bras. À partir de cette position de verrouillage et suite à une nouvelle poussée sur la recharge, dans la direction d'insertion, la coopération de la griffe avec la rampe, décale angulairement la butée de la recharge de la butée complémentaire du bras. En arrêtant la poussée, le ressort 70 repousse alors la recharge hors de son logement dans le bras, libérant ainsi le verrouillage de la liaison de la recharge au bras. According to yet another example, not illustrated, the charging body has a symmetrical portion of revolution, free to rotate about an axis parallel to the direction of insertion of the refill in its housing. This symmetrical part of revolution can in particular be cylindrical, tubular, conical or frustoconical. This part forms a ramp, for example a helical ramp, and a stop. The stop preferably extends over a limited angular section of the symmetrical portion of revolution. The arm includes him claw, intended to cooperate with the ramp, and a stop complementary to the stop formed on the charging body. Thus, during the insertion of the refill in the housing, the cooperation of the claw and the ramp guides the abutment of the refill opposite the complementary abutment formed on the arm so that the abutment and the complementary abutment are in contact under the effect of the elastic body in the locking position of the connection of the refill and the arm. From this locking position and following a new thrust on the refill, in the direction of insertion, the cooperation of the claw with the ramp angularly shifts the abutment of the refill of the complementary abutment of the arm. By stopping the thrust, the spring 70 then pushes the refill out of its slot in the arm, thus releasing the locking of the connection of the refill to the arm.
La figure 7 illustre encore une autre variante 100 d'une pièce à main d'un exemple de dispositif de traitement de la chevelure.  Figure 7 illustrates yet another variant 100 of a handpiece of an example of a device for treating the hair.
Dans cette variante, la recharge est insérée dans son logement contre l'action du ressort 70, jusqu'à ce que la saillie de l'élément mâle soit emprisonnée dans l'élément de réception de l'élément femelle. Un clapet 80 est ici prévu sur le bras 18, qui présente une position d'ouverture permettant une telle insertion de la recharge dans son logement.  In this variant, the refill is inserted into its housing against the action of the spring 70, until the projection of the male element is trapped in the receiving element of the female element. A valve 80 is here provided on the arm 18, which has an open position allowing such insertion of the refill in its housing.
Une fois l'élément mâle emprisonnée dans l'élément de réception de l'élément femelle, l'utilisateur rabat le clapet 80, dans une position de fermeture, pour former une butée mécanique empêchant le ressort 70 de repousser la recharge hors de son logement. Dans cette position, le ressort 70 contraint élastiquement la recharge contre une butée formée sur ou par le clapet 80. Pour ce faire, le clapet 80 est monté pivotant sur le bras 18, ici autour d'un axe parallèle à la direction d'insertion de la recharge 32 dans son logement.  Once the male element trapped in the receiving element of the female element, the user folds the valve 80, in a closed position, to form a mechanical stop preventing the spring 70 to push the refill out of its housing . In this position, the spring 70 resiliently forces the refill against an abutment formed on or by the valve 80. To do this, the valve 80 is pivotally mounted on the arm 18, here around an axis parallel to the insertion direction recharge 32 in his home.
Pour déverrouiller la liaison de la recharge au bras, l'utilisateur repousse sur la recharge, dans la même direction et le même sens que pour l'insertion de celle-ci dans son logement et relève le clapet 80. En relâchant alors la recharge, il permet au ressort 70 de repousser la recharge 32 hors de son logement.  To unlock the connection of the refill arm, the user pushes on the refill, in the same direction and the same direction as for the insertion of it in its housing and lifts the valve 80. While releasing the refill, it allows the spring 70 to push the refill 32 out of its housing.
La présente invention présente l'avantage de verrouiller la recharge quand celle- ci est située au fond dans son logement, c'est-à-dire dans sa position d'utilisation.  The present invention has the advantage of locking the refill when it is located at the bottom in its housing, that is to say in its position of use.
De préférence, l'élément mâle - le plus simple - est intégré au corps de la recharge, et l'élément femelle - plus complexe - est intégré au bras du dispositif, pour réduire les coûts de fabrication des recharges. Cependant, la configuration opposée (élément mâle sur le bras du dispositif, élément femelle sur la recharge) peut également être envisagée. La solution proposée permet également la suppression d'un bouton spécifique de verrouillage qui doit être manipulé par l'utilisateur. Le dispositif présente ainsi une esthétique plus épurée, très appréciée des utilisateurs. L'invention permet aussi de proposer un appareil dont le nettoyage est plus aisé. Preferably, the male element - the simplest - is integrated into the body of the refill, and the female element - more complex - is integrated into the arm of the device, to reduce the cost of manufacturing refills. However, the opposite configuration (male element on the device arm, female element on the refill) can also be considered. The proposed solution also allows the removal of a specific lock button that must be manipulated by the user. The device thus has a more refined aesthetic, highly appreciated by users. The invention also makes it possible to provide an appliance whose cleaning is easier.
La solution proposée est également très fiable. Le dispositif de verrouillage du type à libération par poussée donne un aspect technologique à la fonction de fixation de la cartouche, cet aspect étant très apprécié des utilisateurs. Ce dispositif de verrouillage contribue en outre à garantir à l'utilisateur que seules les cartouches compatibles sont utilisables avec le dispositif de traitement de la chevelure, afin de fournir un traitement optimal de la chevelure et/ou d'assurer que l'appareil est apte à fonctionner correctement, ce qui pourrait ne pas être le cas avec des cartouches non compatibles.  The proposed solution is also very reliable. The thrust release type locking device gives a technological aspect to the fastening function of the cartridge, this aspect being very appreciated by the users. This locking device also contributes to guaranteeing the user that only the compatible cartridges can be used with the hair treatment device, in order to provide an optimal treatment of the hair and / or to ensure that the device is fit. to work properly, which may not be the case with non-compatible cartridges.
L'invention n'est pas limitée aux exemples de réalisation qui viennent d'être décrits, dont les caractéristiques peuvent se combiner au sein de variantes non illustrées.  The invention is not limited to the embodiments which have just been described, the characteristics of which can be combined within non-illustrated variants.
En outre, les butées mécaniques décrites pour maintenir le dispositif de verrouillage en position verrouillée peuvent être remplacées par des éléments magnétiques, notamment des aimants, l'attraction entre deux aimants remplaçant la formation d'une butée mécanique.  In addition, the mechanical stops described to maintain the locking device in the locked position can be replaced by magnetic elements, including magnets, the attraction between two magnets replacing the formation of a mechanical stop.
L'expression « comportant un » doit être comprise comme étant synonyme de « comprenant au moins un ».  The phrase "with one" should be understood as synonymous with "comprising at least one".
