Description

BROSSE A MANCHE AMOVIBLE RETENU PAR AIMANT BRUSH WITH REMOVABLE HANDLE RETAINED BY MAGNET
DOMAINE TECHNIQUE DE L’INVENTION TECHNICAL FIELD OF THE INVENTION
[0001] La présente invention concerne les dispositifs destinés à être utilisés pour des cheveux, notamment pour le procédé de coiffage des cheveux dénommé « brushing », ou « mise en forme », ou encore « thermobrossage », et pour la coupe des cheveux. The present invention relates to devices intended to be used for hair, in particular for the hair styling process called "brushing", or "shaping", or even "heat brushing", and for cutting hair.
[0002] Le brushing est une technique de séchage et de mise en forme des cheveux bien connue des coiffeurs, qui exige l'action combinée d'un séchoir à main et d'une brosse à main essentiellement cylindrique. Cette technique de coiffage consiste à travailler, mèche par mèche, les cheveux humides à S'aide d'une brosse, d'un peigne ou des doigts, tout en les séchant avec un séchoir à main. Brushing is a technique for drying and shaping hair well known to hairdressers, which requires the combined action of a hand dryer and an essentially cylindrical hand brush. This styling technique involves working, strand by strand, damp hair using a brush, comb or fingers, while drying them with a hand dryer.
[0003] Dans cette technique, le coiffeur peut donner du volume ou boucler une chevelure. Pour cela, il doit prendre à chaque fois une mèche de cheveux mouillés, l'enrouler sur la brosse à main, et la sécher au séchoir à cheveux, de façon à obtenir une forme déterminée par le diamètre de la brosse. [0003] In this technique, the hairdresser can give volume or curl hair. For this, he must each time take a lock of wet hair, wind it on the hand brush, and dry it in the hair dryer, so as to obtain a shape determined by the diameter of the brush.
[0004] Un tel procédé exige que le coiffeur puisse utiliser aisément, en succession, des brosses de diamètre différent, adaptées chacune à une longueur ou une position différente de mèche de cheveux. Such a method requires that the hairdresser can easily use, in succession, brushes of different diameter, each adapted to a different length or position of lock of hair.
[0005] Pour faciliter le brushing, le document US 2009/0229624 A1 décrit un kit comprenant une pluralité de rouleaux de brushing, au moins un manche de préhension amovible auquel peut être fixé mécaniquement l’un des rouleaux de brushing, et un boîtier de rangement définissant un compartiment de réception dimensionné pour recevoir et contenir les rouleaux de brushing. La fixation mécanique du rouleau de brushing sur un manche de préhension amovible nécessite la manœuvre d’un bouton de déverrouillage pour libérer le rouleau de brushing à l’écart du manche de préhension amovible. Il est alors nécessaire d’utiliser deux mains, l’une pour tenir le manche de préhension amovible, l’autre pour retenir le rouleau de brushing jusqu’à leur séparation, ce qui n’est pas ergonomique et oblige le coiffeur à relâcher le séchoir à cheveux. To facilitate brushing, document US 2009/0229624 A1 describes a kit comprising a plurality of brushing rollers, at least one removable gripping handle to which one of the brushing rollers can be mechanically attached, and a housing of storage defining a receiving compartment sized to receive and contain the brushing rollers. Mechanical attachment of the brushing roller to a removable gripper handle requires the operation of a release button to release the brushing roller away from the removable gripper. It is then necessary to use two hands, one to hold the removable gripping handle, the other to hold the brushing roller until they are separated, which is not ergonomic and requires the hairdresser to release the handle. hair-dryer.
[0006] Le document US 2013/0133683 A1 décrit un rouleau de brushing qui est retenu sur un manche amovible par un aimant. Le manche amovible comprend un tronçon de préhension et un tronçon de fixation configuré en cône pour s’engager de façon amovible dans un logement conique correspondant d’un élément d’adaptation de manche prévu à l’intérieur du rouleau de brushing. Deux surfaces plates opposées sont prévues à la fois sur le tronçon conique de fixation et dans le logement conique de l’élément d’adaptation de manche, pour s’opposer à la rotation relative du manche amovible et du rouleau de brushing. Un aimant de retenue est prévu dans le fond du logement conique de l’élément d’adaptation de manche, et un aimant de retenue est également prévu à l’extrémité du tronçon de fixation du manche, pour retenir axialement le manche et le rouleau de brushing engagés l’un sur l’autre en position d’assemblage. Un flasque circonférentiel est prévu à l’extrémité proximale du rouleau de brushing, pour constituer une surface d’appui pour le désengagement du rouleau de brushing sur le manche par une poussée axiale. Lors de l’engagement du manche dans un rouleau de brushing, l’utilisateur doit nécessairement orienter angulairement le manche autour de sa direction axiale jusqu’à faire coïncider les surfaces plates, à défaut de quoi le rouleau de brushing peut se coincer mécaniquement en une position inacceptable sur le manche et sans être retenu par les aimants. L’assemblage nécessite donc une manoeuvre par deux mains. Par ailleurs, le désengagement du manche vis-à-vis du rouleau de brushing n'est pas aisé, car il existe un risque important de coincement qui empêche la manoeuvre par une seule main de l’utilisateur. [0006] Document US 2013/0133683 A1 describes a brushing roller which is retained on a removable handle by a magnet. The removable handle comprises a gripping section and an attachment section configured in a cone to removably engage in a corresponding conical housing of a handle adaptation element provided inside the brushing roller. Two opposing flat surfaces are provided both on the conical securing section and in the conical housing of the handle adapter element, to oppose the relative rotation of the removable handle and the brushing roller. A retainer magnet is provided in the bottom of the tapered housing of the handle adapter member, and a retainer magnet is also provided at the end of the handle attachment section, to axially retain the handle and the handle roller. brushing engaged one on the other in the assembly position. A circumferential flange is provided at the proximal end of the brushing roller, to constitute a bearing surface for the disengagement of the brushing roller from the handle by an axial thrust. When engaging the handle in a brushing roller, the user must necessarily orient the handle angularly around its axial direction until the flat surfaces coincide, failing which the brushing roller may become mechanically stuck in one unacceptable position on the handle and without being retained by the magnets. The assembly therefore requires an operation by two hands. Moreover, the disengagement of the handle vis-à-vis the brushing roller is not easy, because there is a significant risk of jamming which prevents the operation by one hand of the user.
[0007] Le document US 2011/114111 A1 décrit notamment un mode de réalisation dans lequel un manche amovible comprend un tronçon de fixation conique qui vient s’engager dans une ouverture conique ménagée à l’intérieur d’un rouleau à cheveux, les deux éléments étant retenus par des aimants. Des rainures et nervures alternées, prévues tout au long du tronçon de fixation conique et de l’ouverture conique, empêchent la rotation relative axiale du manche et du rouleau à cheveux, et forment des dents. Les dents illustrées sur les figures ne sont pas jointives, ni en ce qui concerne la partie mâle, ni en ce qui concerne la partie femelle. La description n’apporte aucune information supplémentaire. Autrement dit, aucune des portions dentées n’est continue. [0007] Document US 2011/114111 A1 describes in particular an embodiment in which a removable handle comprises a conical fixing section which engages in a conical opening formed inside a hair roller, the two elements being retained by magnets. Alternating grooves and ribs, provided throughout the tapered attachment section and the tapered opening, prevent relative axial rotation of the handle and hair roller, and form teeth. The teeth illustrated in the figures are not contiguous, neither as regards the male part, nor as regards the female part. The description does not provide any additional information. In other words, none of the toothed portions are continuous.
[0008] Le document US 2017/086558 A1 décrit notamment un mode de réalisation dans lequel un rouleau à cheveux comprend un tronçon de fixation conique mâle qui vient s’engager dans une ouverture conique ménagée à l’intérieur d’un manche, les deux éléments étant retenus par un aimant et une couronne métallique.

EXPOSE DE L’INVENTION DISCLOSURE OF THE INVENTION
[0010] L'invention a pour objet de faciliter encore la manipulation des instruments utilisés pour la coiffure des cheveux, en permettant en particulier au coiffeur de garder en permanence dans une main le séchoir à cheveux ou autre instrument de coiffure et de prendre, de manipuler ou de reposer de sa seule autre main les autres instruments de coupe ou de mise en forme des mèches de cheveux lors d’une étape de brushing. The object of the invention is to further facilitate the handling of the instruments used for hairdressing the hair, in particular by allowing the hairdresser to keep the hair dryer or other hairdressing instrument in one hand at all times and to take, to handle or rest with his only other hand the other tools for cutting or shaping locks of hair during a brushing step.
[0011] L’invention a en particulier pour objet de faciliter la manipulation et l’interchangeabilité d’instruments différents, comportant chacun un corps d’instrument conformé pour interagir avec la chevelure et sur lequel peut se fixer de façon amovible un manche de préhension. [0011] The object of the invention is in particular to facilitate the handling and interchangeability of different instruments, each comprising an instrument body shaped to interact with the hair and on which a gripping handle can be removably attached. .
[0012] Selon un premier aspect de l’invention, la manipulation doit en particulier être facilitée par le fait que l’utilisateur n’a pas besoin d’indexer la position angulaire du manche de préhension lors de sa fixation sur un corps d’instrument, et par le fait que l’invention évite les risques de blocage mécanique du manche lors de sa fixation sur un corps d’instrument ainsi que lors de son retrait à l’écart d’un corps d’instrument. According to a first aspect of the invention, the handling should in particular be facilitated by the fact that the user does not need to index the angular position of the gripping handle when it is fixed to a body of instrument, and by the fact that the invention avoids the risk of mechanical blocking of the handle when it is fixed to an instrument body as well as when it is withdrawn away from an instrument body.
[0013] Selon un deuxième aspect, l’invention vise à conserver les propriétés avantageuses d’un corps d’instrument creux et d’un manche de préhension à température réduite. [0013] According to a second aspect, the invention aims to retain the advantageous properties of a hollow instrument body and of a reduced temperature gripping handle.
[0014] Selon un troisième aspect, l’invention vise à faciliter la manipulation et l’interchangeabilité des instruments en favorisant sensiblement l’engagement du manche de préhension sur le corps d'instrument. [0014] According to a third aspect, the invention aims to facilitate the handling and interchangeability of instruments by significantly promoting the engagement of the gripping handle on the instrument body.
[0015] Selon un quatrième aspect, l’invention vise à faciliter la manipulation et l’interchangeabilité des instruments en favorisant d’une part une bonne solidarisation du corps d’instrument sur le manche de préhension, et d’autre part la séparation volontaire du manche de préhension à l’écart du corps d’instrument, à l’aide d’une seule main sans effort excessif et sans risque de blocage. According to a fourth aspect, the invention aims to facilitate the handling and interchangeability of instruments by promoting on the one hand a good attachment of the instrument body to the gripping handle, and on the other hand the voluntary separation of the gripping handle away from the instrument body, using only one hand without excessive effort and without risk of jamming.
[0016] Pour atteindre ces buts ainsi que d'autres, l'invention propose un instrument pour traiter une chevelure, ayant les caractéristiques du préambule ci -a près : To achieve these and other goals, the invention provides an instrument for treating hair, having the characteristics of the preamble below:
- un corps d’instrument, conformé pour interagir avec la chevelure, et ayant un élément d’adaptation de manche solidaire du corps d’instrument, - an instrument body, shaped to interact with the hair, and having a neck adaptation element integral with the instrument body,
- un manche amovible, comprenant un tronçon de préhension, et comprenant un élément de fixation configuré pour se fixer de façon amovible, dans une position d’assemblage, à l’élément d’adaptation de manche, - a removable handle, comprising a gripping section, and comprising a fixing element configured to be removably attached, in an assembly position, to the handle adaptation element,
- un logement creux, prévu dans l’un de l’élément de fixation et de l'élément d’adaptation de manche, - a hollow housing, provided in one of the fixing element and the handle adaptation element,
- une excroissance, prévue dans l’autre de l’élément de fixation et de l’élément d’adaptation de manche, l’excroissance étant conformée pour s’engager par translation selon une direction axiale et se bloquer dans ledit logement creux en position d’assemblage, a protuberance, provided in the other of the fixing element and of the handle adaptation element, the protrusion being shaped to engage by translation in an axial direction and to lock in said hollow housing in position assembly,
- un premier aimant, logé dans l’un du logement creux et de l’excroissance, coopérant avec un élément d’attraction magnétique logé dans l’autre du logement creux et de l’excroissance, pour retenir de façon amovible par attraction magnétique l’excroissance dans ledit logement creux en position d’assemblage, a first magnet, housed in one of the hollow housing and of the protuberance, cooperating with a magnetic attraction element housed in the other of the hollow housing and of the protuberance, to removably retain by magnetic attraction the 'protuberance in said hollow housing in the assembly position,
- des moyens anti-rotation conformés pour s'opposer à une rotation relative du corps d’instrument et du manche amovible autour de la direction axiale en position d’assemblage, - anti-rotation means shaped to oppose a relative rotation of the instrument body and the removable handle around the axial direction in the assembly position,
- les moyens anti-rotation comprenant une couronne de dents de logement prévue dans ledit logement creux, et une couronne de dents d’excroissance prévue sur ladite excroissance, les dents de logement s’imbriquant avec les dents d’excroissance en position d’assemblage. - the anti-rotation means comprising a ring of housing teeth provided in said hollow housing, and a crown of protruding teeth provided on said protuberance, the housing teeth interlocking with the protrusion teeth in the assembly position .
[0017] Selon ledit premier aspect de l’invention, constituant une première invention indépendante, on prévoit de combiner les caractéristiques dudit préambule avec les caractéristiques additionnelles suivantes : According to said first aspect of the invention, constituting a first independent invention, provision is made to combine the characteristics of said preamble with the following additional characteristics:
- l’une de la couronne de dents de logement et de la couronne de dents d’excroissance est dentée de façon continue selon toute sa circonférence, c'est-à- dire que les dents successives de cette couronne de dents sont jointives, adjacentes les unes à la suite des autres, et - one of the crown of housing teeth and of the crown of protruding teeth is continuously toothed along its entire circumference, that is to say that the successive teeth of this crown of teeth are contiguous, adjacent one after the other, and
- l’autre de la couronne de dents de logement et de la couronne de dents d’excroissance est dentée de façon discontinue selon sa circonférence, c'est-à-dire que les dents successives de cette couronne de dents sont à l’écart l’une de l’autre, séparées l’une de l’autre par un segment de cylindre ou de cône. [0018] L’effet technique obtenu par la combinaison des caractéristiques additionnelles est de faciliter la manipulation, par le fait que l’utilisateur n’a pas besoin d’indexer la position angulaire du manche de préhension lors de sa fixation sur le corps d’instrument, et on évite simultanément les risques de blocage mécanique du manche lors de sa fixation sur le corps d’instrument et lors de son retrait. - the other of the crown of housing teeth and of the crown of protruding teeth is toothed discontinuously according to its circumference, that is to say that the successive teeth of this crown of teeth are apart one from the other, separated from each other by a cylinder or cone segment. The technical effect obtained by the combination of additional features is to facilitate handling, by the fact that the user does not need to index the angular position of the gripping handle when it is fixed to the body of 'instrument, and simultaneously avoids the risk of mechanical blocking of the handle during its attachment to the instrument body and during its removal.
[0019] En effet, quelle que soit la position angulaire relative du corps d’instrument et du manche amovible lorsque l’utilisateur les présente l’un face à l’autre pour leur assemblage, les dents de la couronne dentée de façon discontinue trouvent chacune de façon certaine leur place dans l’une des dents de la couronne dentée de façon continue, sans risquer de buter contre un espace intermédiaire entre deux dents successives de la couronne dentée de façon continue. Par ailleurs, l’espacement des dents de la couronne dentée de façon discontinue évite efficacement les problèmes de blocage mécanique des dents les unes dans les autres, blocage susceptible d’empêcher l’insertion complète et/ou le retrait du manche. Indeed, regardless of the relative angular position of the instrument body and the removable handle when the user presents them facing each other for their assembly, the teeth of the ring gear are discontinuously found. each with certainty their place in one of the teeth of the ring gear continuously, without the risk of abutting against an intermediate space between two successive teeth of the ring gear continuously. Furthermore, the discontinuous spacing of the teeth of the ring gear effectively avoids the problems of mechanically locking the teeth into each other, which may prevent complete insertion and / or removal of the handle.
[0020] L’utilisateur peut ainsi exécuter les opérations suivantes d’une seule main, à savoir prendre un premier corps d’instrument en manipulant le seul manche de préhension amovible, procéder au traitement de la chevelure avec le premier corps d’instrument, retirer le manche pour laisser le corps d’instrument en place sur la chevelure ou sur un support, venir prendre un autre corps d’instrument sur le support à l'aide du manche de préhension amovible, procéder au traitement de la chevelure avec ledit autre corps d’instrument, et ainsi de suite. Simultanément à cela, le coiffeur peut, de son autre main, manœuvrer le séchoir à cheveux ou autre outil de traitement. The user can thus perform the following operations with one hand, namely take a first instrument body by manipulating the single removable gripping handle, process the hair with the first instrument body, remove the handle to leave the instrument body in place on the hair or on a support, take another instrument body from the support using the removable gripping handle, proceed to treat the hair with said other instrument body, and so on. Simultaneously with this, the hairdresser can, with his other hand, operate the hair dryer or other treatment tool.
[0021] En pratique, pour réduire encore les risques de blocage mécanique, ladite couronne de dents qui est dentée de façon discontinue selon sa circonférence peut avantageusement comporter un nombre de dents compris entre 0.5 et 30 % du nombre de dents de ladite couronne de dents qui est dentée de façon continue. In practice, to further reduce the risks of mechanical blockage, said ring of teeth which is toothed discontinuously around its circumference may advantageously include a number of teeth between 0.5 and 30% of the number of teeth of said ring of teeth. which is continuously toothed.
[0022] Selon un mode de réalisation avantageux, la couronne de dents de logement est dentée de façon continue, tandis que la couronne de dents d’excroissance comporte 3 dents réparties à 120° selon sa circonférence. [0022] According to an advantageous embodiment, the ring of housing teeth is continuously toothed, while the ring of protruding teeth has 3 teeth distributed at 120 ° according to its circumference.
[0023] De préférence, les dents des couronnes de dents ont une forme triangulaire à angles vifs. Preferably, the teeth of the tooth crowns have a triangular shape with sharp angles.
[0024] De la sorte, il n’y a en pratique aucun risque que les sommets des dents respectives des couronnes de dents de logement et d'excroissance restent en appui les uns contre les autres lors de l’engagement du manche sur le corps d'instrument, et s’opposent ainsi à la pénétration complète des dents les unes dans les autres jusqu’à une position de retenue efficace par les aimants. In this way, there is in practice no risk that the tops of the respective teeth of the housing and protrusion tooth crowns remain in abutment against each other during the engagement of the handle on the body. instrument, and thus oppose the complete penetration of the teeth into each other to an effective retaining position by the magnets.
[0025] De préférence, le logement comporte un tronçon effilé dans lequel s’adapte sans jeu un tronçon effilé correspondant de l’excroissance en position d’assemblage. On entend par « tronçon effilé » un tronçon dans lequel le diamètre de section transversale varie progressivement, de façon monotone, entre une extrémité de tronçon à grand diamètre et une extrémité de tronçon à petit diamètre. Preferably, the housing comprises a tapered section into which fits without play a corresponding tapered section of the protuberance in the assembly position. The term “tapered section” is understood to mean a section in which the cross-sectional diameter varies progressively, monotonically, between an end of a section with a large diameter and an end of a section with a small diameter.
[0026] De la sorte, en position d’assemblage, les tronçons effilés respectifs sont en appui l’un dans l’autre, retenus dans cette position par l’action des aimants, et s’opposant à tout mouvement relatif transversal du manche par rapport au corps d’instrument. In this way, in the assembly position, the respective tapered sections are supported one in the other, retained in this position by the action of the magnets, and opposing any transverse relative movement of the handle relative to the instrument body.
[0027] Les couronnes de dents peuvent avantageusement être ménagées sur le grand diamètre des tronçons effilés, ou éventuellement sur le petit diamètre des tronçons effilés. The crowns of teeth can advantageously be provided on the large diameter of the tapered sections, or possibly on the small diameter of the tapered sections.
[0028] Selon un mode de réalisation avantageux, les tronçons effilés sont des tronçons coniques. According to an advantageous embodiment, the tapered sections are conical sections.
[0029] La couronne de dents de logement et la couronne de dents d’excroissance peuvent avantageusement occuper une longueur inférieure à la moitié de la longueur du logement creux et de l'excroissance, de préférence inférieure au tiers de la longueur du logement creux et de l’excroissance. De la sorte, les risques de blocage mécanique sont encore réduits, l’engagement et le dégagement du manche sur le corps d’instrument sont encore facilités. The crown of housing teeth and the crown of protruding teeth can advantageously occupy a length less than half the length of the hollow housing and the protuberance, preferably less than a third of the length of the hollow housing and of the outgrowth. In this way, the risks of mechanical jamming are further reduced, the engagement and disengagement of the handle on the instrument body are further facilitated.
[0030] Selon ledit second aspect de l’invention, constituant une seconde invention indépendante, on prévoit de combiner les caractéristiques du préambule avec les caractéristiques additionnelles suivantes : According to said second aspect of the invention, constituting a second independent invention, provision is made to combine the characteristics of the preamble with the following additional characteristics:
- l’élément d’adaptation de manche est une pièce rapportée et fixée en saillie sur une extrémité du corps d’instrument. - the neck adaptation element is an attached part and fixed projecting on one end of the instrument body.
[0031] L’effet technique obtenu par la combinaison de ces caractéristiques additionnelles est de préserver l'espace intérieur du corps d'instrument, pour conserver les fonctionnalités traditionnelles du corps d’instrument, en particulier les propriétés avantageuses d’un corps d’instrument creux plus léger, à plus faible inertie thermique, et perméable au flux d’air d’un séchoir à cheveux. En outre, cette pièce rapportée peut constituer un élément d’isolation thermique entre le manche de préhension et le corps d’instrument lui-même susceptible d’être échauffé par un séchoir à cheveux. The technical effect obtained by the combination of these additional characteristics is to preserve the interior space of the instrument body, to retain the traditional functions of the instrument body, in particular the advantageous properties of a body of the instrument. Lighter hollow instrument, with lower thermal inertia, and permeable to the air flow of a hair dryer. In addition, this insert can constitute a thermal insulation element between the gripping handle and the instrument body itself capable of being heated by a hair dryer.
[0032] Selon ledit troisième aspect de l’invention, constituant une troisième invention indépendante, selon un premier mode de réalisation, on prévoit de combiner les caractéristiques du préambule avec la caractéristique additionnelle suivante : According to said third aspect of the invention, constituting a third independent invention, according to a first embodiment, provision is made to combine the characteristics of the preamble with the following additional characteristic:
- l’élément d'adaptation de manche comporte un tronçon d'entrée en entonnoir plus évasé que le reste du logement. - the sleeve adaptation element has a funnel-shaped inlet section that is more flared than the rest of the housing.
[0033] L’effet technique obtenu par l’ajout de cette caractéristique additionnelle est de faciliter encore l’engagement du manche sur un corps d’instrument, cet engagement étant réalisé dès lors que l’axe longitudinal du manche se trouve à proximité de l’axe longitudinal du corps d’instrument, sans qu’une correspondance exacte des deux axes soit nécessaire. The technical effect obtained by adding this additional feature is to further facilitate the engagement of the handle on an instrument body, this engagement being achieved when the longitudinal axis of the handle is close to the longitudinal axis of the instrument body, without an exact correspondence of the two axes being necessary.
[0034] Selon ledit troisième aspect de l’invention, constituant une troisième invention indépendante, selon un second mode de réalisation, on prévoit de combiner les caractéristiques du préambule avec la caractéristique additionnelle suivante : According to said third aspect of the invention, constituting a third independent invention, according to a second embodiment, provision is made to combine the characteristics of the preamble with the following additional characteristic:
- la couronne de dents de logement et la couronne de dents d’excroissance occupent une longueur inférieure à la moitié de la longueur du logement creux et de l’excroissance, de préférence inférieure au tiers de la longueur du logement creux et de l’excroissance. - the crown of housing teeth and the crown of protruding teeth occupy a length less than half the length of the hollow housing and the protuberance, preferably less than a third of the length of the hollow housing and the protuberance .
[0035] L’effet technique obtenu par l'ajout de cette caractéristique additionnelle est de faciliter encore l’engagement du manche sur un corps d'instrument. [0035] The technical effect obtained by adding this additional feature is to further facilitate the engagement of the neck on an instrument body.
[0036] Selon ledit quatrième aspect de l’invention, constituant une quatrième invention indépendante, on prévoit de combiner les caractéristiques du préambule avec la caractéristique additionnelle suivante : According to said fourth aspect of the invention, constituting a fourth independent invention, provision is made to combine the characteristics of the preamble with the following additional characteristic:
- l’élément d’adaptation de manche comporte, sur sa surface extérieure, une gorge annulaire conformée pour permettre l’engagement de l'extrémité d’un doigt d’utilisateur. - The handle adaptation element has, on its outer surface, an annular groove shaped to allow engagement of the end of a user's finger.
[0037] L’effet technique obtenu par l’ajout de cette caractéristique additionnelle est que, lorsqu’un doigt d'utilisateur est engagé dans la gorge annulaire, ce doigt peut exercer une poussée axiale pour éjecter le corps d’instrument à l’écart du manche de préhension, et cette poussée est exercée au plus près de l’axe longitudinal du manche et du corps d’instrument. Cela facilite encore la séparation du manche et du corps d’instrument, en évitant les risques de blocage mécanique qui sont plus fréquents lors d’une poussée désaxée. The technical effect obtained by adding this additional feature is that, when a user's finger is engaged in the annular groove, this finger can exert an axial thrust to eject the instrument body to the distance of the gripping handle, and this thrust is exerted as close as possible to the longitudinal axis of the handle and of the instrument body. This further facilitates the separation of the handle and the body of the instrument, avoiding the risks of mechanical jamming which are more frequent during an offset thrust.

DESCRIPTION DES MODES DE REALISATION PREFERES DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0048] Dans le mode de réalisation tel qu'illustré sur les figures 1 à 9, l'instrument 1 pour traiter une chevelure est illustré à titre d’exemple par une brosse de brushing, comprenant un corps d’instrument 2 et un manche amovible 3. In the embodiment as illustrated in Figures 1 to 9, the instrument 1 for treating hair is illustrated by way of example by a brushing brush, comprising an instrument body 2 and a handle removable 3.
[0049] Dans cet exemple, le corps d'instrument 2 est un corps de brosse de brushing, comprenant une cage tubulaire 20, généralement cylindrique à section transversale circulaire, se développant le long d’un axe longitudinal l-l, en métal ou en matière plastique, comportant des trous périphériques traversants par lesquels sont engagés des poils de brosse 21. La cage tubulaire 20 est ouverte à une extrémité distale 22. In this example, the instrument body 2 is a brushing brush body, comprising a tubular cage 20, generally cylindrical with a circular cross section, developing along a longitudinal axis II, made of metal or of material plastic, comprising through peripheral holes through which are engaged brush bristles 21. The tubular cage 20 is open at a distal end 22.
[0050] A son autre extrémité, ou extrémité proximale 23, la cage tubulaire 20 est fermée par un élément d’adaptation de manche 24. At its other end, or proximal end 23, the tubular cage 20 is closed by a handle adaptation element 24.
[0051] Le manche amovible 3 comprend un tronçon de préhension 4, et comprend un élément de fixation 30 ayant un tronçon de fixation 5. The removable handle 3 comprises a gripping section 4, and comprises a fastening element 30 having a fastening section 5.
[0052] Le tronçon de fixation 5 du manche 3 est conformé pour se fixer de manière amovible sur ou dans l’élément d’adaptation de manche 24. [0053] Dans la réalisation illustrée sur les figures, l’élément d’adaptation de manche 24 est une pièce rapportée fixée axialement en saillie sur l’extrémité proximale 23 du corps d’instrument 2. De la sorte, l’élément d’adaptation de manche 24 laisse libre l’espace intérieur de la cage tubulaire 20 du corps d’instrument. Dans l’exemple illustré, cette disposition permet par exemple de laisser pénétrer dans l’espace intérieur de la cage 20 l’air de soufflage des cheveux. The fixing section 5 of the handle 3 is shaped to be removably fixed on or in the handle adaptation element 24. In the embodiment illustrated in the figures, the sleeve adaptation element 24 is an attached piece fixed axially projecting on the proximal end 23 of the instrument body 2. In this way, the element of adaptation of handle 24 leaves free the interior space of the tubular cage 20 of the instrument body. In the example illustrated, this arrangement makes it possible, for example, to allow the air for blowing the hair to enter the interior space of the cage 20.
[0054] L’élément d'adaptation de manche 24 comporte un logement creux 25, ayant un tronçon effilé creux 26, par exemple conique, et un tronçon d’entrée 27 en entonnoir plus évasé que le tronçon effilé creux 26. Selon un exemple de réalisation, le tronçon effilé creux 26 peut avoir une longueur de 10.95 mm, un petit diamètre de 11.87 mm, un grand diamètre de 16.71 mm Le fond du logement creux 25 est obturé par un premier aimant 6 dont l’un des pôles forme la face d'extrémité du logement creux 25. The sleeve adaptation element 24 comprises a hollow housing 25, having a hollow tapered section 26, for example conical, and an inlet section 27 funnel-shaped more flared than the hollow tapered section 26. According to one example embodiment, the hollow tapered section 26 may have a length of 10.95 mm, a small diameter of 11.87 mm, a large diameter of 16.71 mm The bottom of the hollow housing 25 is closed by a first magnet 6, one of the poles of which forms the end face of the hollow housing 25.
[0055] Le tronçon d’entrée 27 du logement creux 25 comporte une couronne de dents de logement 28. Le tronçon d’entrée 27 peut avoir une longueur d’environ 4 mm.[0055] The inlet section 27 of the hollow housing 25 has a ring of housing teeth 28. The inlet section 27 may have a length of about 4 mm.
Les dents de logement de la couronne de dents de logement 28 sont jointives, de sorte que ladite couronne de dents de logement 28 est dentée de façon continue. The housing teeth of the housing tooth ring 28 are contiguous, so that said housing tooth ring 28 is continuously toothed.
[0056] Le tronçon de fixation de l’élément de fixation 30 du manche 3 est une excroissance 5 axiale formant l’extrémité distale du manche 3. Dans la réalisation illustrée, l’excroissance 5 axiale forme le tronçon d’extrémité d’un élément de fixation 30 sous forme d’un embout de manche rapporté dans l’extrémité distale d’un corps de manche 31. The fixing section of the fixing element 30 of the handle 3 is an axial protuberance 5 forming the distal end of the handle 3. In the illustrated embodiment, the axial protuberance 5 forms the end section of a fixing element 30 in the form of a handle end piece attached to the distal end of a handle body 31.
[0057] L’excroissance 5 axiale présente une surface extérieure effilée 40 de forme complémentaire de celle du tronçon effilé creux 26, par exemple conique. Selon un exemple de réalisation, la surface extérieure effilée 40 peut avoir une longueur de 10.7 mm, un petit diamètre de 12 mm, un grand diamètre de 16.8 mm. Selon son diamètre le plus large, l’excroissance 5 axiale comporte une couronne de dents d’excroissance 50. La couronne de dents d’excroissance 50 peut avoir une longueur inférieure à la moitié de la longueur de la surface extérieure effilée 40, par exemple une longueur de 4 mm. Plus avantageusement, la couronne de dents d’excroissance 50 peut avoir une longueur inférieure au tiers de la longueur de la surface extérieure effilée 40, par exemple une longueur de 3 mm. Comme on le voit mieux sur les figures 5 et 9, les dents d’excroissance de la couronne de dents d’excroissance 50 sont disjointes, de sorte que ladite couronne de dents d’excroissance 50 est dentée de façon discontinue selon sa circonférence. De préférence, la couronne de dents d’excroissance 50 comporte un nombre de dents compris entre 0.5 et 30 % du nombre de dents de la couronne de dents de logement 28. Dans l'exemple illustré, la couronne de dents d’excroissance 50 comporte 3 dents réparties à 120° selon sa circonférence, tandis que la couronne de dents de logement 28 comporte 16 dents. The axial protuberance 5 has a tapered outer surface 40 of a shape complementary to that of the hollow tapered section 26, for example conical. According to an exemplary embodiment, the tapered outer surface 40 may have a length of 10.7 mm, a small diameter of 12 mm, a large diameter of 16.8 mm. Depending on its widest diameter, the axial protuberance 5 has a crown of protrusion teeth 50. The protrusion tooth ring 50 may have a length less than half the length of the tapered outer surface 40, for example. a length of 4 mm. More advantageously, the crown of protruding teeth 50 may have a length less than one third of the length of the tapered outer surface 40, for example a length of 3 mm. As can be seen better in FIGS. 5 and 9, the protruding teeth of the crown of protruding teeth 50 are separate, so that said crown of protruding teeth 50 is toothed discontinuously along its circumference. Preferably, the crown of protruding teeth 50 comprises a number of teeth between 0.5 and 30% of the number of teeth of the crown of teeth of housing 28. In the example illustrated, the crown of protruding teeth 50 comprises 3 teeth distributed at 120 ° according to its circumference, while the crown of housing teeth 28 comprises 16 teeth.
[0058] Comme on le voit mieux sur les figures 3 et 4, les dents de la couronne de dents de logement 28 ont une forme triangulaire à angles vifs, Les dents d’excroissance de la couronne de dents d’excroissance 50 présentent un profil complémentaire de celui des dents de logement de la couronne de dents de logement 28, avec des formes triangulaires à angles vifs. De la sorte, on évite les risques de coincement pouvant se produire lorsque deux arêtes supérieures se présentent l’une sur l’autre, car les angles vifs provoquent un basculement d’un côté ou de l’autre du triangle afin que le manche 3 et le corps d’instrument 2 pivotent l’un par rapport à l'autre autour de l’axe longitudinal l-l pour que les couronnes de dents 28 et 50 s’engagent l’une dans l’autre et que l’ensemble se mette naturellement en position emmanchée. As best seen in Figures 3 and 4, the teeth of the housing teeth ring 28 have a triangular shape with sharp angles, The protrusion teeth of the protrusion tooth ring 50 have a profile complementary to that of the housing teeth of the housing tooth crown 28, with triangular shapes with sharp angles. In this way, the risks of jamming that can occur when two upper edges are placed on top of each other are avoided, because the sharp angles cause a tilt to one side or the other of the triangle so that the handle 3 and the instrument body 2 pivot relative to each other about the longitudinal axis II so that the crowns of teeth 28 and 50 engage one another and the assembly fits. naturally in the fitted position.
[0059] Le pas des dents de la couronne de dents d’excroissance 50 et de la couronne de dents de logement 28 est choisi suffisamment fin pour que la correction d’angle de pivotement du manche 3 et du corps d’instrument 2 l’un par rapport à l’autre soit minime. Le pas peut avantageusement être compris entre 10 % et 25 % du diamètre des couronnes de dents. Dans l'exemple illustré, dans lequel la couronne de dents de logement 28 comporte 16 dents, ce rapport est de 12.5 %. The pitch of the teeth of the crown of protruding teeth 50 and of the crown of housing teeth 28 is chosen sufficiently fine so that the pivot angle correction of the handle 3 and of the instrument body 2 l ' one compared to the other is minimal. The pitch can advantageously be between 10% and 25% of the diameter of the tooth crowns. In the example illustrated, in which the ring of housing teeth 28 has 16 teeth, this ratio is 12.5%.
[0060] L’extrémité distale 52 de l’excroissance 5 axiale comporte un logement 53 dans lequel est engagé et fixé un élément d’attraction magnétique, par exemple sous forme d’un deuxième aimant 7 dont l’un des pôles constitue la face d’extrémité frontale de l’élément de fixation 30 du manche 3, ou sous forme d’une pièce en un matériau apte à être attiré par le champ magnétique produit par le premier aimant 6. The distal end 52 of the axial protuberance 5 comprises a housing 53 in which is engaged and fixed a magnetic attraction element, for example in the form of a second magnet 7, one of the poles of which constitutes the face. end of the fixing element 30 of the handle 3, or in the form of a part made of a material capable of being attracted by the magnetic field produced by the first magnet 6.
[0061] Pour assurer leur fonction de maintien relatif du manche 3 et du corps 2 en position d’assemblage, le premier aimant 6 et le deuxième aimant 7 sont orientés et positionnés de façon que leurs pôles respectifs 61 et 71 soient en regard l’un de l’autre, au contact l’un de l’autre ou écartés l’un de l’autre selon un faible entrefer maîtrisé, et de natures différentes c’est-à-dire avec un pôle nord face à un pôle sud. To ensure their function of relative holding of the handle 3 and the body 2 in the assembly position, the first magnet 6 and the second magnet 7 are oriented and positioned so that their respective poles 61 and 71 are facing the one from the other, in contact with each other or separated from each other according to a small controlled air gap, and of different natures, that is to say with a north pole facing a south pole .
[0062] On peut avantageusement maîtriser l’entrefer entre les pôles respectifs 61 et 71 en prévoyant des moyens de butée axiale sous forme d’une couronne annulaire 51 qui, en position d’assemblage, vient en appui sur une face d’extrémité proximale 29 de l’élément d'adaptation de manche 24. The air gap between the respective poles 61 and 71 can advantageously be controlled by providing axial stop means in the form of an annular ring 51 which, in the assembled position, bears on a proximal end face 29 of the handle adapter 24.
[0063] On considère à nouveau les figures 1 à 3, illustrant l’élément d'adaptation de manche 24. La surface extérieure périphérique de l’élément d’adaptation de manche 24 comporte une gorge annulaire 100 conformée pour permettre l’engagement de l’extrémité d’un doigt d’utilisateur. Ladite gorge annulaire 100 constitue une zone de plus faible diamètre, permettant à l’utilisateur d'appliquer une poussée axiale plus proche de l’axe longitudinal l-l. En pratique, le diamètre de fond de gorge est inférieur au diamètre du corps de manche 31 , et inférieur au diamètre du corps d’instrument 2 dans le cas d’une brosse à cheveux. Consider again Figures 1 to 3, illustrating the sleeve adaptation element 24. The peripheral outer surface of the sleeve adaptation element 24 comprises an annular groove 100 shaped to allow the engagement of the end of a user's finger. Said annular groove 100 constitutes a zone of smaller diameter, allowing the user to apply an axial thrust closer to the longitudinal axis II. In practice, the throat bottom diameter is less than the diameter of the handle body 31, and less than the diameter of the instrument body 2 in the case of a hairbrush.
[0064] De préférence, comme illustré, la gorge 100 peut avoir un profil longitudinal dissymétrique, formant à partir du fond de gorge un faible ressaut en direction du manche 3, et formant un ressaut de plus grand diamètre en direction du corps d’instrument 2. Selon un exemple de réalisation, le diamètre de fond de gorge peut être d’environ 18 mm, le faible ressaut en direction du manche 3 peut avoir un diamètre d’environ 22 mm, la partie de plus grand diamètre peut avoir un diamètre d’environ 40 mm. La partie de plus grand diamètre constitue une zone d’appui favorisant le dégagement du manche 3 vis-à-vis du corps d’instrument 2 par poussée axiale du doigt d’utilisateur. Preferably, as illustrated, the groove 100 may have an asymmetrical longitudinal profile, forming from the bottom of the groove a slight projection in the direction of the handle 3, and forming a projection of larger diameter in the direction of the instrument body 2. According to an exemplary embodiment, the diameter of the groove bottom may be about 18 mm, the small projection in the direction of the handle 3 may have a diameter of about 22 mm, the part with the largest diameter may have a diameter. about 40 mm. The part of larger diameter constitutes a support zone favoring the release of the handle 3 vis-à-vis the instrument body 2 by axial thrust of the user's finger.
[0065] On considère à nouveau les figures 5 à 8 illustrant l’élément de fixation de manche 30. Dans son tronçon 32 qui se fixe dans le corps de manche 31 , l’élément de fixation de manche 30 présente une forme généralement cylindrique, avec un méplat latéral 33 pour son blocage en rotation dans le corps de manche 31 , et avec une rainure longitudinale 34 dans laquelle est engagé un aimant latéral 35 (figure 1) ou une pièce de matériau ferromagnétique apte à coopérer avec un aimant d’un support extérieur sur lequel peut être entreposé l’instrument 1. En regard de l’aimant latéral 35, le corps de manche 31 comporte une surface latérale 36 généralement plane, facilitant le positionnement et le maintien en position entreposée de l’instrument 1 sur un support extérieur. Consider again Figures 5 to 8 illustrating the handle fixing element 30. In its section 32 which is fixed in the handle body 31, the handle fixing element 30 has a generally cylindrical shape, with a lateral flat 33 for its locking in rotation in the handle body 31, and with a longitudinal groove 34 in which is engaged a lateral magnet 35 (FIG. 1) or a piece of ferromagnetic material capable of cooperating with a magnet of a external support on which the instrument 1 can be stored. Opposite the lateral magnet 35, the handle body 31 comprises a generally flat lateral surface 36, facilitating the positioning and the maintenance in the stored position of the instrument 1 on a exterior support.
[0066] Dans le mode de réalisation illustré sur les figures, le logement creux 25 est prévu dans l’élément d’adaptation de manche 24, et l’excroissance 5 est prévue dans l’élément de fixation 30 du manche 3. En alternative, sans sortir du cadre de la présente invention, on pourra prévoir de réaliser le logement creux dans l’élément de fixation 30 du manche 3, et de réaliser l’excroissance 5 sur l’élément d’adaptation de manche 24. In the embodiment illustrated in the figures, the hollow housing 25 is provided in the handle adaptation element 24, and the protuberance 5 is provided in the fixing element 30 of the handle 3. Alternatively , without departing from the scope of the present invention, provision can be made to produce the hollow housing in the fixing element 30 of the handle 3, and to produce the protuberance 5 on the handle adaptation element 24.
[0067] Dans le mode de réalisation illustré sur les figures, les couronnes de dents 28 et 50 sont ménagées sur le grand diamètre des tronçons effilés 26 et 40. En alternative, sans sortir du cadre de la présente invention, on pourra prévoir de réaliser les couronnes de dents 28 et 50 sur le petit diamètre des tronçons effilés 26 et 40, ou sur un diamètre intermédiaire. In the embodiment illustrated in the figures, the crowns of teeth 28 and 50 are provided on the large diameter of the tapered sections 26 and 40. Alternatively, without departing from the scope of the present invention, provision can be made to achieve the crowns of teeth 28 and 50 on the small diameter of the tapered sections 26 and 40, or on an intermediate diameter.
[0068] Dans le mode de réalisation illustré sur les figures, l’élément d’adaptation de manche 24 est une pièce rapportée et fixée sur le corps d’instrument 2. En alternative, sans sortir du cadre de la présente invention, on pourra prévoir un corps d’instrument 2 comportant, d’une seule pièce, l’élément d’adaptation de manche 24. In the embodiment illustrated in the figures, the handle adaptation element 24 is an attached part and fixed to the instrument body 2. In alternatively, without departing from the scope of the present invention, it is possible to provide an instrument body 2 comprising, in a single piece, the handle adaptation element 24.
[0069] Dans le mode de réalisation illustré sur les figures, l’élément de fixation 30 est une pièce rapportée sur le tronçon de préhension 4 du manche 3. En alternative, sans sortir du cadre de la présente invention, on pourra prévoir de réaliser un manche 3 comportant, d’une seule pièce, l’élément de fixation 30. In the embodiment illustrated in the figures, the fixing element 30 is a part attached to the gripping section 4 of the handle 3. Alternatively, without departing from the scope of the present invention, provision can be made to achieve a handle 3 comprising, in one piece, the fixing element 30.
[0070] Dans le mode de réalisation illustré sur les figures, l’instrument 1 est une brosse de brushing pour la chevelure. Toutefois, l’invention pourra être appliquée avantageusement à d’autres formes d’instrument pour traiter une chevelure. [0071] La présente invention peut avantageusement être appliquée à un ensemble d'instruments pour traiter une chevelure, ledit ensemble comprenant au moins un manche amovible et une pluralité de corps d’instrument tels que décrits ci-dessus. L’utilisateur peut aisément adapter le manche sur l’un quelconque de la pluralité de corps d’instrument, et peut aisément retirer le manche dudit corps d’instrument, sans risque de blocage, et d'une seule main. L’adaptation du manche 3 sur le corps d'instrument 2 peut se faire par simple présentation de l’excroissance 5 axiale à l’entrée du logement creux 25, l’attraction produite par les aimants 6 et 7 étant suffisante pour parfaire ensuite l'adaptation du manche 3 en position assemblée. In the embodiment illustrated in the figures, the instrument 1 is a blow-drying brush for the hair. However, the invention can be applied advantageously to other forms of instrument for treating hair. The present invention can advantageously be applied to a set of instruments for treating hair, said set comprising at least one removable handle and a plurality of instrument bodies as described above.
