Abstract

The curler has a body (2) comprising a flap (10) adapted to occupy, by deformation of the body, a position in which the flap maintains the rolling of a hair mesh (M) around part of the body. A base (3) is integrated with the body and comprises a slot in which a portion (M1) of the mesh is disposed, where the portion is not rolled around the body. The flap is formed at an axial end (11) opposite to an axial end (9) of the body.

Description

La présente invention a pour objet un bigoudi permettant notamment la mise en forme d'une mèche de cheveux sans pour autant traiter une portion de cette mèche proche de la racine.The present invention relates to a hair curler, in particular for shaping a lock of hair without treating a portion of this wick close to the root.

Dans l'état de la technique, on connaít classiquement des bigoudis formés d'une armature, généralement cylindrique, autour de laquelle on enroule une mèche de cheveux, une pique étant enfoncée au travers de la mèche enroulée tout en traversant ladite armature en vue de maintenir l'enroulement de ladite mèche. Un problème posé par ces bigoudis apparaít notamment lorsque l'on cherche à enrouler une mèche de cheveux longs sur un tel bigoudi. En effet, si on enroule toute la mèche sur un même bigoudi, alors il faut enrouler la mèche en plusieurs épaisseurs. Mais cette disposition surenroulée de la mèche sur elle-même nuit à la pénétration du produit qui lui est ensuite appliqué. De fait, pour enrouler une mèche de cheveux longs et permettre une bonne pénétration du produit dans la mèche de cheveux enroulés, généralement on enroule successivement la mèche sur plusieurs bigoudis, les uns à la suite des autres le long de la mèche. Le nombre de bigoudis à mettre en oeuvre est alors multiplié par deux ou trois, et le temps de manipulation en est d'autant augmenté.In the state of the art, curlers formed are conventionally known. of a frame, generally cylindrical, around which is wrapped a lock of hair, a pike being pushed through the curled lock while traversing said armature in order to maintain the winding of said wick. A problem posed by these curlers appears especially when one try to wrap a lock of long hair on such a hair curler. Indeed, if we wrap the entire wick on the same curler, then you have to wrap the wick in several thicknesses. But this supercoiled disposition of the wick on itself night to the penetration of the product which is then applied to it. In fact, for wrap a lock of long hair and allow good penetration of produced in the wick of coiled hair, usually one wraps successively the wick on several hair curlers, one after the other along the wick. The number of curlers to be used is then multiplied by two or three, and the handling time is increased accordingly.

On connaít de nombreuses variantes de bigoudis, et notamment du document US-5,483,980, on connaít un bigoudi comportant une armature cylindrique autour de laquelle une mèche peut être enroulée, une coque hémicylindrique étant articulée à une extrémité de cette armature de manière à pouvoir être rabattue le moment venu contre le pourtour extérieur de l'armature cylindrique. Le maintien de la position repliée de cette coque sur l'armature est obtenu par un repliement supplémentaire d'un organe rigide déformable, dépassant de l'autre extrémité de l'armature.Many variants of curlers are known, and in particular US-5,483,980, there is known a hair curler comprising a frame cylindrical around which a wick can be wound, a hull hemicylindrical being articulated at one end of this frame so as to can be folded when the time comes against the outer edge of the frame cylindrical. Maintaining the folded position of this shell on the frame is obtained by an additional folding of a deformable rigid member, protruding from the other end of the frame.

Par ailleurs, dans les cas où l'utilisatrice souhaite avoir une chevelure bouclée avec un effet "naturel", sans effet gonflant de la masse de cheveux sur le dessus de la tête, il faut que les cheveux implantés sur le dessus de la tête soient enroulés sur une longueur n'allant pas jusqu'aux racines. A cet effet, l'enroulement commence de préférence depuis la pointe de la mèche et s'arrête à distance des racines ou inversement se termine respectivement à distance de ces racines. Les bigoudis pendent alors respectivement aux extrémités des portions non enroulées, proches des racines, de ces mèches. Les bigoudis sont disposés tout autour du dessus du crâne, exagérant le pourtour de la calotte crânienne. En effet, les portions non enroulées ne doivent pas être bouclées, et les bigoudis ne doivent pas être ramenés sur le dessus de la tête lorsque l'on cherche cet effet "naturel". De ce fait, la disposition des bigoudis autour du visage ne donne pas une allure attrayante à la personne ainsi coiffée de bigoudis pendant tout le temps de pause de ces bigoudis.Moreover, in cases where the user wishes to have a hair curly with a "natural" effect, without the swelling effect of the hair mass on the above the head, the hair implanted on the top of the head must be wound on a length not going to the roots. For this purpose, winding preferably starts from the tip of the wick and stops at a distance from roots or conversely ends respectively at a distance from these roots. The curlers then hang respectively at the ends of the non-rolled portions, close to the roots, these locks. Curlers are arranged all around the above the skull, exaggerating the circumference of the cranial cap. Indeed, Unwired portions should not be looped, and hair curlers not be brought back to the top of the head when looking for this "natural" effect. As a result, the arrangement of curlers around the face does not give a pace attractive to the person so wearing curlers during the entire break time of these hair curlers.

Par ailleurs, pour les utilisatrices ayant les cheveux longs, le poids de chaque bigoudi enroulé de surcroít par la portion de mèche correspondante génère une traction sur les racines de ces mèches, ce qui provoque un inconfort notoire chez ces utilisatrices aux cheveux longs.In addition, for users with long hair, the weight of each hair curler wound up by the corresponding wick portion generates traction on the roots of these locks, which causes discomfort notorious among these users with long hair.

On connaít en particulier des bigoudis présentant de tels inconvénients des documents US-2 374 860, FR-2 146 690, US-2 008656 et FR-988 142.Curlers with such disadvantages are particularly known. documents US-2,374,860, FR-2,146,690, US-2,008,656 and FR-988,142.

L'invention a pour objet de résoudre au moins l'un des problèmes énoncés ci-dessus en proposant un bigoudi facile et rapide à mettre en oeuvre, permettant en particulier l'enroulement entier d'une mèche de cheveux longs, et ou pouvant conférer une allure attrayante au visage de la personne qui le porte. Un bigoudi selon l'invention comporte un corps d'axe longitudinal destiné à recevoir un enroulement d'une mèche de cheveux, et un pied solidaire d'une première extrémité axiale dudit corps et comportant une surface apte à reposer sur le cuir chevelu, cette surface ayant une superficie supérieure à celle d'une section transversale d'une partie du corps apte à recevoir l'enroulement de la mèche, le pied comportant des moyens aptes à retenir une portion de ladite mèche non enroulée autour dudit corps, et le corps comportant un rabat apte à occuper, par déformation du corps, une position dans laquelle le rabat maintient l'enroulement de la mèche autour de ladite partie du corps. The object of the invention is to solve at least one of the stated problems above by proposing a curler that is easy and quick to implement, allowing in particular the entire winding of a lock of long hair, and or can give an attractive look to the face of the person wearing it. A curler according to the invention comprises a body of longitudinal axis intended to receive a winding of a strand of hair, and a foot joined to a first axial end of said body and having a surface adapted to rest on the leather hairy, this area having an area greater than that of a section transverse part of the body adapted to receive the winding of the wick, the foot having means adapted to retain a portion of said wick wrapped around said body, and the body having a flap adapted to occupy by deformation of the body, a position in which the flap maintains the winding wick around said body part.

De préférence, ladite surface est sécante, et par exemple perpendiculaire, avec l'axe longitudinal du corps.Preferably, said surface is secant, and for example perpendicular, with the longitudinal axis of the body.

Avantageusement, le pied comporte une fente dans laquelle la portion de mèche est retenue. Par exemple, la fente peut être formée au travers du pied, de telle sorte que la mèche est insérée par coulissement le long d'un axe de la mèche.Advantageously, the foot comprises a slot in which the portion of wick is retained. For example, the slot can be formed through the foot, such that the wick is slidably inserted along an axis of the wick.

Mais de préférence, la fente débouche au niveau d'une bordure du pied, et présente une entrée accessible depuis cette bordure. La mèche peut alors être insérée par translation selon une direction sensiblement orthogonale à un axe formé par ladite mèche. Par exemple, cette entrée est alors chanfreinée pour faciliter l'insertion de la mèche dans la fente. En variante, la fente peut former un creux en V dans le pied, de telle sorte qu'un espacement entre les deux bras du V définit l'entrée par laquelle la mèche est introduite relativement au bigoudi. Dans ce cas, une zone de jonction entre les deux bras du V correspond à un fond de la fente, dans lequel la mèche peut être retenue.But preferably, the slot opens at a border of the foot, and has an entry accessible from this border. The wick can then be inserted by translation in a direction substantially orthogonal to an axis formed by said wick. For example, this entry is then chamfered to facilitate the insertion of the wick into the slot. Alternatively, the slot can form a hollow V in the foot, so that a spacing between the two arms of the V defines the entry through which the wick is introduced relative to the curler. In this case, a junction zone between the two arms of the V corresponds to a bottom of the slot, in which the wick can be retained.

Avantageusement, la fente débouche du pied à distance d'une jonction entre le corps et ce pied. Le pied formant un angle non nul avec l'axe longitudinal du corps, la première portion de mèche retenue dans le pied se prolonge alors par une deuxième portion de mèche s'étendant entre le pied et le corps autour duquel le reste de la mèche sera ensuite enroulé. Ainsi ces première et deuxième portions de mèche ne sont pas enroulées autour du corps et ne formeront pas de boucles.Advantageously, the slot opens out of the foot at a distance from a junction between the body and that foot. The foot forming a non-zero angle with the longitudinal axis of the body, the first portion of wick retained in the foot is then extended by a second portion of wick extending between the foot and the body around which the rest of the wick will then be rolled up. So these first and second portions of wick are not wrapped around the body and will not form loops.

De préférence, on dispose le pied de telle sorte que la première portion, et le cas échéant la deuxième portion, soient proches des racines de la mèche à enrouler autour du bigoudi. Par exemple, on dispose le pied de telle sorte que la surface apte à reposer sur le cuir chevelu permette de maintenir la première portion de mèche dressée relativement au cuir chevelu. Le pied comporte dans ce cas, et de préférence, une fente dans laquelle la portion de mèche est retenue, cette fente débouchant entre autre au niveau de cette surface. La fente peut être définie dans un plan, ce plan formant alors un angle non nul avec ladite surface du pied de telle sorte que la mèche insérée dans cette fente, forme également un angle non nul relativement au cuir chevelu. La mèche est donc relevée relativement au cuir chevelu.Preferably, the foot is arranged so that the first portion, and where appropriate the second portion, be close to the roots of the wick in wrap around the curler. For example, the foot is placed so that the surface able to rest on the scalp allows to maintain the first portion of wick erect relative to the scalp. The foot has in this case, and preferably, a slot in which the wick portion is retained, this slot opening among others at this level. The slot can be defined in a plane, this plane then forming a non-zero angle with said surface of the foot so that the wick inserted into this slot, also forms a nonzero angle relative to the scalp. The wick is raised relatively to the scalp.

Le pied présente une épaisseur correspondant à une longueur minimum de portion de mèche pouvant être retenue dressée relativement au cuir chevelu. Par exemple, la portion de mèche retenue dans le pied est dressée à 90° relativement au cuir chevelu. Le pied comporte par exemple une portion dépassant latéralement du pourtour du corps.The foot has a thickness corresponding to a minimum length of portion of wick that can be held erect relative to the scalp. By for example, the portion of wick retained in the foot is erected at 90 ° relatively to the scalp. The foot comprises for example a portion exceeding laterally around the body.

Avantageusement, les moyens aptes à retenir une portion de mèche, formés dans le pied, sont élastiquement déformables. Ils peuvent donc se rabattre élastiquement sur ladite portion de mèche pour la retenir par contrainte élastique. Dans les cas où ces moyens se présentent sous la forme d'une fente, cette fente comporte alors deux bordures en vis-à-vis, par exemple accolées au repos, et apte à être élastiquement espacées l'une de l'autre. Après insertion d'une mèche dans la fente, les deux bordures tendent à retourner dans leur position initiale de repos, ce qui permet de contraindre et retenir une portion de mèche disposée entre ces deux bordures.Advantageously, the means capable of retaining a portion of wick, formed in the foot, are elastically deformable. They can therefore fall back resiliently on said wick portion to retain it by elastic stress. In cases where these means are in the form of a slot, this slot then has two edges vis-à-vis, for example contiguous to the rest, and able to be elastically spaced from each other. After inserting a wick in the slot, both edges tend to return to their original position of rest, which makes it possible to constrain and retain a portion of wick arranged between these two borders.

De préférence, le corps est au moins en partie réalisé dans un matériau élastiquement déformable, par exemple en élastomère ou en mousse, la mousse pouvant être à cellules ouvertes ou fermées. On choisit de préférence un matériau léger tel qu'une mousse. De préférence, le pourtour extérieur de la mousse, le cas échéant, présente des cavités ouvertes, ce qui améliore l'engagement et la rétention de la mèche sur le bigoudi.Preferably, the body is at least partly made of a material elastically deformable, for example elastomer or foam, the foam can be open or closed cells. A material is preferably chosen lightweight such as a foam. Preferably, the outer periphery of the foam, the case appropriate, has open cavities, which improves the commitment and retention of the wick on the curler.

Avantageusement, le pied et le corps sont réalisés dans le même matériau. Encore plus avantageusement, le bigoudi est intégralement réalisé dans un même matériau, ce qui simplifie les tests de compatibilité du bigoudi relativement à tout un ensemble de produits susceptibles d'être appliqués sur la mèche une fois enroulée autour dudit bigoudi. Advantageously, the foot and the body are made of the same material. Even more advantageously, the curler is integrally made in one and the same material, which simplifies curler compatibility testing for everything a set of products that can be applied to the wick once wrapped around said curler.

Selon un mode de réalisation particulier, le pied peut présenter une forme sensiblement parallélépipédique et comporter un axe d'allongement principal. Cet axe d'allongement principal forme alors un angle non nul avec l'axe longitudinal du corps.According to a particular embodiment, the foot can have a shape substantially parallelepipedic and include a main axis of elongation. This main elongation axis then forms a non-zero angle with the longitudinal axis from the body.

Avantageusement, le pied est assemblé à une extrémité du corps relativement à l'axe longitudinal. Et dans le cas où le corps et le pied ont respectivement des formes sensiblement parallélépipédiques, alors le bigoudi présente une forme globale de L, et ce notamment pour les modes de réalisations pour lesquels l'axe longitudinal du corps est orthogonal à une surface du pied.Advantageously, the foot is assembled at one end of the body relative to the longitudinal axis. And in the case where the body and the foot have respectively substantially parallelepipedal shapes, then the curler presents a global form of L, and in particular for the embodiments for which the longitudinal axis of the body is orthogonal to a surface of the foot.

Avantageusement, le pied est collé sur le corps. Alternativement, il est soudé, par exemple par soudure ultrasons ou thermosoudage, sur le corps. En variante encore le pied et le corps sont monolithiques.Advantageously, the foot is stuck on the body. Alternatively, it is welded, for example by ultrasonic welding or heat sealing, on the body. In still variant the foot and the body are monolithic.

De préférence, un bigoudi selon l'invention est obtenu par estampage. Par exemple on estampe le corps et le pied dans un panneau comportant au moins deux faces planes parallèles entre elles, l'assemblage se faisant au cours d'une étape ultérieure.Preferably, a curler according to the invention is obtained by stamping. By example, the body and the foot are stamped in a panel with at least two plane faces parallel to each other, the assembly being done during a subsequent step.

De préférence, le corps comporte un pourtour extérieur apte à faciliter l'enroulement de la mèche. Par exemple, le corps est au moins en partie fileté de telle sorte que le filetage du corps sert à guider l'enroulement de la mèche. En variante, le corps peut être au moins en partie cranté, les crans étant alors de préférence disposés avec un espacement régulier à la surface du corps. Préférentiellement, dans les cas où le corps est sensiblement parallélépipédique, le corps comporte au moins deux surfaces opposées et crantées. Dans ce cas, ces deux surfaces peuvent être crantées de manière alternée, de telle sorte qu'un cran d'un côté soit en vis-à-vis d'un creux situé entre deux crans du côté opposé.Preferably, the body has an outer periphery capable of facilitating the winding of the wick. For example, the body is at least partly threaded with such that the thread of the body serves to guide the winding of the wick. In Alternatively, the body may be at least partly notched, the notches being preferably arranged with regular spacing on the surface of the body. Preferably, in cases where the body is substantially parallelepipedal, the body has at least two opposite and notched surfaces. In that case, these two surfaces can be notched alternately, so that a notch on one side facing a depression located between two notches on the opposite side.

De préférence la mèche est enroulée en hélice autour de l'axe longitudinal du corps. Preferably the wick is helically wound around the longitudinal axis from the body.

Avantageusement le bigoudi comporte une paroi extérieure imperméable, de manière à éviter que du produit imprégné sur la mèche ne soit absorbé par le bigoudi et empêche une imprégnation optimale de ladite mèche avec une quantité limitée de produit appliqué.Advantageously, the curler comprises an impermeable outer wall, in order to prevent the product impregnated on the wick from being absorbed by the curler and prevents optimal impregnation of said wick with a quantity limited product applied.

De manière avantageuse, lorsque la mèche est complètement enroulée autour du corps, en partant des racines en direction des pointes, alors ces pointes peuvent être maintenues relativement au bigoudi par ledit rabat. Généralement le rabat se situe à une seconde extrémité axiale du corps, selon l'axe longitudinal, opposée à la première extrémité axiale du corps au niveau de laquelle commence l'enroulement, et en particulier à l'opposé, de l'extrémité au niveau de laquelle le pied est rattaché au corps. Pour maintenir l'enroulement, le rabat est déplacé d'une première position vers une deuxième position relativement au corps de telle sorte qu'une extrémité de la mèche enroulée est maintenue en place, dans la deuxième position, coincée entre une partie du corps et le rabat.Advantageously, when the wick is completely wound around the body, starting from the roots towards the tips, then these tips can be maintained relative to the curler by said flap. Generally the flap is located at a second axial end of the body, along the longitudinal axis, opposite to the first axial end of the body where it begins the winding, and in particular the opposite, of the end at which the foot is attached to the body. To maintain the winding, the flap is moved from a first position to a second position relative to the body of such so that one end of the coiled wick is held in place, in the second position, wedged between a part of the body and the flap.

De préférence, le corps comporte un raidisseur apte à être déformé de manière semi permanente, en particulier de manière à maintenir la déformation du corps permettant au rabat de maintenir l'enroulement de la mèche autour de ladite partie du corps. Lorsque le corps est déformé, le raidisseur est également déformé de telle sorte que le corps s'allonge le long de plusieurs segments consécutifs pouvant être sécants entre eux. Par exemple, ce raidisseur peut comporter une âme filiforme, rigide mais néanmoins déformable, par exemple un fil de cuivre, interne au corps et allongé selon l'axe longitudinal. De préférence, ce raidisseur est prévu pour déboucher au niveau de la première extrémité du corps masquée par le pied.Preferably, the body comprises a stiffener capable of being deformed by semi-permanent way, in particular so as to maintain the deformation of the body allowing the flap to maintain the winding of the wick around said Part of the body. When the body is deformed, the stiffener is also deformed so that the body extends along several consecutive segments can be secant between them. For example, this stiffener may comprise a filamentary core, rigid but nevertheless deformable, for example a copper wire, internal to the body and elongated along the longitudinal axis. Preferably, this stiffener is intended to debouch at the level of the first end of the masked body by the foot.

The invention will be better understood on reading the description which follows and on examining the figures which accompany it. These are presented only as an indication and in no way limitative of the invention. The figures show:
  • Figure 1: a schematic view of a hair curler according to the invention set up on a lock of hair;

La Figure 1 montre un bigoudi 1 selon l'invention mis en place sur une mèche M de cheveux d'une utilisatrice. Le bigoudi 1 comporte un corps 2 comportant un axe longitudinal X correspondant également à un axe d'allongement principal de ce corps 2. Dans le mode de réalisation représenté le corps 2 est sensiblement parallélépipédique tel que l'axe longitudinal X est parallèle à une longueur la plus grande de ce parallélépipède. La mèche M est enroulée en formant des spires autour du corps 2. De préférence ce corps 2 comporte des arêtes arrondies pour ne pas créer de courbures aiguës de la mèche en de multiples points autour du corps 2. Le pourtour extérieur du corps 2 sera détaillé ci-dessous.Figure 1 shows a hair curler 1 according to the invention set up on a Wick M of a user's hair. Curler 1 has a body 2 having a longitudinal axis X also corresponding to an axis of the main extension of this body 2. In the embodiment shown body 2 is substantially parallelepipedic such that the longitudinal axis X is parallel to a greater length of this parallelepiped. The wick M is wound by forming turns around the body 2. Preferably this body 2 has rounded edges so as not to create sharp curvatures of the wick in multiple points around the body 2. The outer rim of the body 2 will be detailed below.

Comme cela est représenté sur la Figure 1, le corps 2 est disposé relativement au crâne de l'utilisatrice, et notamment relativement à la zone de ce crâne d'où est isolée la mèche M, de manière à ce que l'axe longitudinal X soit sensiblement perpendiculaire à cette surface du crâne. La mèche M étant ici sélectionnée sur le dessus du crâne, le corps 2 est alors dressé sur le crâne dans le prolongement longitudinal du visage. Lorsque l'ensemble de la chevelure divisée en autant de mèches telles que M est enroulé autour de bigoudis tels que 1, le visage de l'utilisatrice est alors recouvert de pointes s'étendant radialement du pourtour extérieur de son crâne, à la manière des piquants dépassant d'un hérisson. Les bigoudis sont alors disposés en corolle autour du visage.As shown in Figure 1, the body 2 is disposed relative to the skull of the user, and in particular with respect to the area of that skull from which the wick M is isolated, so that the longitudinal axis X is substantially perpendicular to this surface of the skull. The wick M being here selected on the top of the skull, the body 2 is then erected on the skull in the longitudinal extension of the face. When the whole of the hair divided into as many locks as M is wrapped around hair curlers such as 1, the wearer's face is then covered with radially extending spikes the outer circumference of his skull, in the manner of quills exceeding a hedgehog. Curlers are then arranged in a corolla around the face.

Pour maintenir la position du corps 2 relativement au crâne de l'utilisatrice, le bigoudi 1 comporte une partie de base 3 formant un pied pour l'application du bigoudi 1 sur le crâne. Cette partie de base ou pied 3 est solidaire du corps 2.To maintain the position of the body 2 relative to the skull of the user, the curler 1 comprises a base portion 3 forming a foot for the application of the curler 1 on the skull. This base part or foot 3 is integral with the body 2.

En particulier, le pied 3 comporte une première surface 4 destinée à être orientée en regard du crâne et une deuxième surface 5 au niveau de laquelle est par exemple réalisée une jonction avec le corps 2. L'axe longitudinal X est par exemple orthogonal à cette deuxième surface 5. Dans l'exemple représenté, le pied 3 a une forme découpée dans un support sensiblement parallélépipédique, les surfaces 4 et 5 étant alors rectangles et parallèles entre elles, et le corps 2 étant dressé perpendiculairement à la deuxième surface 5, il est donc dressé perpendiculairement à la zone du crâne contre laquelle est appliquée la première surface 4, et au niveau de laquelle est prélevée la mèche M.In particular, the foot 3 has a first surface 4 intended to be facing the skull and a second surface 5 at which is for example made a junction with the body 2. The longitudinal axis X is by orthogonal example to this second surface 5. In the example shown, the foot 3 has a cut shape in a substantially parallelepiped support, the surfaces 4 and 5 then being rectangular and parallel to each other, and the body 2 being erected perpendicularly to the second surface 5, it is erected perpendicular to the area of the skull against which is applied the first surface 4, and at which the wick M.

Par exemple, ce corps 2 comporte une portion autour de laquelle la mèche est destinée à être enroulée. Cette portion est de section transversale, dans un plan orthogonal à l'axe longitudinal X, circulaire, triangulaire, carrée ou encore polygonale. La section transversale de cette portion du corps 2 peut présenter une superficie S1 variable le long de l'axe X. Dans tous les cas, la superficie S1 est inférieure à la superficie S2 de la première surface 4. La superficie S2 est par exemple supérieure au double de la superficie S1.For example, this body 2 has a portion around which the wick is intended to be rolled up. This portion is of cross section, in a plane orthogonal to the longitudinal axis X, circular, triangular, square or polygonal. The cross section of this portion of the body 2 may have a S1 area variable along the X axis. In all cases, S1 area is less than the area S2 of the first surface 4. The area S2 is example greater than twice the area S1.

De facto, et en particulier lorsque l'axe longitudinal X est perpendiculaire à cette surface 4, le pied 3 dépasse latéralement d'au moins un côté du corps 2, comme cela est représenté sur les Figures 1 à 3. En variante, le corps 2 peut également être retenu sur la surface supérieure 5 à distance des bordures de cette surface.De facto, and especially when the longitudinal axis X is perpendicular to this surface 4, the foot 3 protrudes laterally from at least one side of the body 2, as shown in Figures 1 to 3. Alternatively, the body 2 can also be retained on the top surface 5 away from the curbs of this surface.

Figures 1 à 4, un angle 6 formé entre le pied 3, et plus particulièrement entre la deuxième surface 5 de ce pied 3, et l'axe longitudinal X est alors de 90°. Dans les cas où le pied 3 présente un axe d'allongement principal, cet axe d'allongement principal forme alors un angle non nul avec l'axe longitudinal X, par exemple sensiblement égal à la valeur de l'angle 6.1 to 4, an angle 6 formed between the foot 3, and more particularly between the second surface 5 of this foot 3, and the longitudinal axis X is then 90 °. In cases where the foot 3 has a main axis of elongation, this axis the principal elongation then forms a non-zero angle with the longitudinal axis X, by example substantially equal to the value of the angle 6.

Si l'on souhaite proposer une orientation irrégulière relativement au crâne, mais néanmoins dressée, des piques formées par les bigoudis selon l'invention lorsqu'ils sont disposés dans la chevelure, le bigoudi 1 peut être alternativement réalisé en proposant un angle non nul différant de 90° entre le pied 3 et l'axe longitudinal X du corps 2.If one wishes to propose an irregular orientation relative to the skull, but nevertheless erect, spades formed by hair curlers according to the invention when arranged in the hair, the curler 1 can be alternatively realized by proposing a non-zero angle differing from 90 ° between the foot 3 and the axis longitudinal X of the body 2.

Le pied 3 qui est de préférence disposé à proximité des racines de la mèche M, comporte des moyens pour retenir une portion M1 de cette mèche M en particulier à proximité des racines. En particulier, la portion de mèche M1 est disposée dans une fente 7 formée dans l'épaisseur du pied 3, l'épaisseur correspondant à une distance déterminée entre les surfaces 4 et 5. Dans le cas où les surfaces 4 et 5 sont parallèles, l'épaisseur est constante. De préférence, on choisit l'épaisseur du pied 3 de telle sorte que la longueur de la portion de mèche M1 pouvant être retenue dans la fente 7 soit significativement longue, pour préserver cette portion de mèche M1 de tout enroulement autour du corps 2. Le pied 3 peut aussi être réalisé en présentant une épaisseur variable.The foot 3 which is preferably arranged near the roots of the wick M, comprises means for retaining a portion M1 of this lock M in particular near the roots. In particular, the wicking portion M1 is disposed in a slot 7 formed in the thickness of the foot 3, the thickness corresponding to a determined distance between surfaces 4 and 5. In the case where the surfaces 4 and 5 are parallel, the thickness is constant. Preferably, chooses the thickness of the foot 3 so that the length of the wick portion M1 can be retained in the slot 7 is significantly long, for preserve this portion of wick M1 of any winding around the body 2. The foot 3 can also be achieved by having a variable thickness.

Dans toutes les variantes de réalisation d'un bigoudi selon l'invention, les moyens 7 aptes à retenir la portion de mèche M1, et en particulier la fente 7, sont réalisés dans le pied 3 à distance du corps 2. La fente 7 peut néanmoins s'étendre dans le pied 3 jusqu'à une jonction J entre ce pied 3 et le corps 2.In all the embodiments of a hair curler according to the invention, the means 7 adapted to retain the wick portion M1, and in particular the slot 7, are made in the foot 3 away from the body 2. The slot 7 can nevertheless extend in the foot 3 to a junction J between this foot 3 and the body 2.

Selon un mode de réalisation représenté sur les Figures 1 à 3, une première extrémité axiale 9 du corps 2, relativement à l'axe longitudinal X, est reliée fixement à la surface supérieure 5 du pied 3. Une face 20 présentée à cette première extrémité 9 est définie orthogonalement à l'axe longitudinal X, elle est par exemple soudée sur une zone 21 de cette deuxième surface 5, notamment dans les cas où l'angle 6 est prévu pour être de l'ordre de 90°..According to an embodiment shown in FIGS. 1 to 3, a first axial end 9 of the body 2, relative to the longitudinal axis X, is fixedly connected to the upper surface 5 of the foot 3. A face 20 presented to this first end 9 is defined orthogonally to the longitudinal axis X, it is for example welded on an area 21 of this second surface 5, in particular in cases where the angle 6 is expected to be of the order of 90 °.

En variante, non représentée, le corps 2 pourrait également être relié fixement à ce pied 3 en soudant une portion d'une paroi extérieure 22 du corps 2 située au niveau de cette première extrémité à un chant 23 du pied 3. Ledit chant 23 relie les surfaces 4 et 5 entre elles, et la paroi 22 est de préférence parallèle à l'axe longitudinal X.Alternatively, not shown, the body 2 could also be connected fixed to this foot 3 by welding a portion of an outer wall 22 of the body 2 located at the level of this first end to a song 23 of the foot 3. Said song 23 connects the surfaces 4 and 5 to each other, and the wall 22 is preferably parallel to the longitudinal axis X.

Quels que soient les matériaux utilisés pour réaliser respectivement le corps 2 ou le pied 3, la zone de jonction J permet de garantir la définition de l'angle 6 entre le pied 3 et l'axe longitudinal X, et par ailleurs de maintenir la position angulaire du pied 3 relativement à cet axe longitudinal X. L'enroulement d'une mèche sur le bigoudi 1 ne modifie pas sensiblement cette position angulaire. A tout moment pendant la durée de vie et d'utilisation d'un bigoudi 1 selon l'invention, la position angulaire entre le corps 2 et le pied 3 est sensiblement maintenue à l'identique. Whatever the materials used to achieve respectively the body 2 or foot 3, the junction zone J makes it possible to guarantee the definition of the angle 6 between the foot 3 and the longitudinal axis X, and moreover to maintain the angular position of the foot 3 relative to this longitudinal axis X. The winding a wick on the curler 1 does not substantially change this angular position. At any time during the life and use of a hair curler 1 according to the invention, the angular position between the body 2 and the foot 3 is substantially kept the same.

Dans l'exemple représenté sur la figure 1, les moyens pour retenir la portion de mèche M1 sur le pied 3, et donc non enroulée sur le corps 2, sont matérialisés par la fente 7 en V, la portion de mèche M1 étant disposée dans le creux du V. La portion de mèche M1 est maintenue dans ce creux du fait que le reste M2 de la mèche est ensuite enroulé sur le corps 2 de sorte que son enroulement soit par ailleurs maintenu et que la portion M1 soit de fait aussi maintenue dans la fente 7. L'ouverture du V facilite le placement du pied 3 sur le crâne relativement à ladite mèche M.In the example shown in FIG. 1, the means for retaining the portion of wick M1 on the foot 3, and therefore not wound on the body 2, are materialized by the slot 7 in V, the wick portion M1 being disposed in the hollow of the V. portion of wick M1 is maintained in this hollow because the remainder M2 of the wick is then wound on the body 2 so that its winding is by elsewhere maintained and that the portion M1 is also maintained in the slot 7. The opening of the V facilitates the placement of the foot 3 on the skull relative to said wick M.

En variante, Figures 2 à 4b, les moyens 7 pour retenir la portion de mèche M1 sont matérialisés par la fente 7 réalisée dans l'épaisseur du pied 3. Cette fente 7 comporte des bordures 24 et 25 quasiment accolées. Dans ce cas, le pied 3 est de préférence réalisé dans un matériau élastiquement déformable, de manière à pouvoir écarter ces bordures 24 et 25 l'une de l'autre, et permettre l'introduction de la portion de mèche M1. Dans ce cas, après introduction de la mèche, les bordures 24 et 25 restent légèrement écartées, mais tendent en permanence à revenir vers leur position initiale accolée, ce qui participe à la rétention de la portion M1.Alternatively, Figures 2 to 4b, the means 7 for retaining the portion of wick M1 are materialized by the slot 7 made in the thickness of the foot 3. This slot 7 has edges 24 and 25 almost contiguous. In this case, foot 3 is preferably made of an elastically deformable material, so as to to be able to separate these borders 24 and 25 from each other, and to allow the introduction of the portion of wick M1. In this case, after introduction of the wick, the borders 24 and 25 remain slightly apart, but tend constantly to return to their initial position together, which contributes to the retention of the M1 portion.

De préférence, la fente 7 est traversante et débouche alors en particulier au niveau de la première surface 4 et de la deuxième surface 5, et également à un niveau du chant 23 reliant ces deux surfaces. En particulier, la fente 7 est définie dans un plan orthogonal aux surfaces 4 et 5, et par exemple passant par l'axe longitudinal X.Preferably, the slot 7 is through and opens then in particular at level of the first surface 4 and the second surface 5, and also to a level of the song 23 connecting these two surfaces. In particular, the slot 7 is defined in a plane orthogonal to the surfaces 4 and 5, and for example passing through the axis longitudinal X.

Pour mettre en place un tel bigoudi 1, on soulève la mèche M du crâne, et on translate le bigoudi 1 orthogonalement à un axe de la mèche de telle sorte que la mèche est présentée en vis-à-vis d'une ouverture ou entrée 8 de la fente 7, et telle que la poursuite de cette translation contribue à l'insertion de la mèche M dans cette fente 7 depuis cette entrée 8. Préférentiellement l'entrée 8 de la fente 7 est chanfreinée ce qui facilite l'introduction de la mèche M notamment lorsque les bordures 24 et 25 sont accolées. De préférence aussi, comme représenté Figure 4b, la fente 7 comporte un logement 40 où les bordures 24 et 25 ne sont pas accolées mais définissent un espace dans lequel la mèche sélectionnée peut être disposée, cet espace étant refermé par retour élastique des bordures 24 et 25 l'une sur l'autre. Ce logement 40 permet d'accueillir une mèche de plus gros diamètre, ce qui permet de réduire le nombre de mèches à réaliser pour mettre en forme une chevelure entière.To set up such a curler 1, the wick M of the skull is lifted, and we translate the curler 1 orthogonally to an axis of the wick so that the wick is presented vis-à-vis an opening or entry 8 of the slot 7, and such that the continuation of this translation contributes to the insertion of the lock M in this slot 7 from this input 8. Preferably the input 8 of the slot 7 is chamfered which facilitates the introduction of the wick M especially when the borders 24 and 25 are contiguous. Preferably also, as shown in Figure 4b, the slot 7 comprises a housing 40 where the borders 24 and 25 are not contiguous but define a space in which the selected lock can be disposed, this space being closed by elastic return of the borders 24 and 25 one over the other. This housing 40 can accommodate a wick of larger diameter, which makes it possible to reduce the number of wicks to be made in order to forms an entire hair.

Dans les cas où le creux de la fente 7, où va être retenu la portion de mèche M1, est distant du corps 2, une portion de mèche intermédiaire M3 sortant de cette fente 7, dans le prolongement de la portion M1 n'est pas non plus enroulée sur le corps 2, cette portion intermédiaire M3 ayant une longueur minimale correspondant à la distance séparant le creux de la fente 7 du corps 2. Cette portion intermédiaire M3 est grâce au pied 3 également maintenue non enroulée autour du corps 2.In cases where the hollow of the slot 7, where the portion of wick M1, is remote from the body 2, an intermediate portion of wick M3 outgoing of this slot 7, in the extension of the portion M1 is also not wound on the body 2, this intermediate portion M3 having a length minimum corresponding to the distance between the hollow of the slot 7 of the body 2. This intermediate portion M3 is thanks to the foot 3 also maintained no wrapped around the body 2.

Pour simplifier la réalisation d'un bigoudi 1 selon l'invention, le pied 3 et le corps 2 sont estampés dans un même panneau d'un même matériau, et sont ensuite assemblés. Un tel panneau comporte de préférence deux faces planes parallèles entre elles. Les parties du bigoudi sont découpées de telle sorte qu'une largeur du corps 2, orthogonalement à l'axe longitudinal X, soit sensiblement égale à une largeur du pied 3. Ainsi une multitude de bigoudis peuvent être estampés dans un même panneau en limitant les chutes perdues. L'épaisseur e de ce panneau dans lequel sont estampés le corps 2 et le pied 3 est par exemple de l'ordre de 12 mm.To simplify the production of a hair curler 1 according to the invention, the foot 3 and the body 2 are stamped in the same panel of the same material, and are then assembled. Such a panel preferably comprises two planar faces parallel to each other. The parts of the curler are cut in such a way that width of the body 2, orthogonal to the longitudinal axis X, substantially equal at a width of the foot 3. Thus a multitude of curlers can be stamped in the same panel by limiting lost falls. The thickness e of this panel in which are stamped the body 2 and the foot 3 is for example of the order of 12 mm.

Le corps 2 a dans un mode de réalisation particulier une longueur L le long de l'axe longitudinal X de l'ordre de 205 mm, et une largeur I perpendiculairement à cet axe longitudinal X de l'ordre de 30 mm. Dans ce cas, la superficie S1 d'une section transversale du corps 2 est de l'ordre de 3,6 mm2. Par exemple, la surface 4 a une longueur de l'ordre de 35 mm, et une largeur de l'ordre de 30 mm, et présente au moins un pourtour arrondi dans l'exemple représenté sur les figures 2 à 4b. Dans ce cas, la superficie S2 de la surface 4 est au moins supérieure à 8 mm2. Le rapport de la surface S1 sur la surface S2 est strictement inférieur à 1, et de préférence compris entre 0,2 et 0,8, et de préférence entre 0,4 et 0,6, et plus avantageusement encore de l'ordre de 0,5. The body 2 has in a particular embodiment a length L along the longitudinal axis X of the order of 205 mm, and a width I perpendicular to this longitudinal axis X of the order of 30 mm. In this case, the area S1 of a cross section of the body 2 is of the order of 3.6 mm 2 . For example, the surface 4 has a length of the order of 35 mm, and a width of the order of 30 mm, and has at least one rounded periphery in the example shown in Figures 2 to 4b. In this case, the area S2 of the surface 4 is at least greater than 8 mm 2 . The ratio of the surface S1 to the surface S2 is strictly less than 1, and preferably between 0.2 and 0.8, and preferably between 0.4 and 0.6, and still more preferably of the order of 0.5.

Alternativement, le corps 2 et le pied 3 peuvent être réalisés dans des matériaux différents. Alternativement encore, le corps 2 et le pied 3 peuvent être monolithiques et découpés dans un bloc formant un corps plein pour former une seule pièce.Alternatively, the body 2 and the foot 3 can be made in different materials. Alternatively again, the body 2 and the foot 3 can be monolithic and cut into a block forming a solid body to form a single piece.

Par exemple, ils peuvent être réalisés respectivement en mousse, par exemple une mousse de chlorure de polyvinyle (PVC), de polyuréthane, de polyether, de polyester, ou d'un élastomère du type des caoutchoucs naturels (NBR) ou synthétiques (SBR), de caoutchoucs de butyle, de silicone, de nitrile, d'EPDM (copolymère d'un diène avec de l'éthylène et du propylène) et comporte de préférence au moins 10 % de cellules ouvertes. Selon un premier mode de réalisation, le corps 2 est réalisé dans une mousse à cellules fermées. Ainsi du produit ne peut pas s'imprégner dans la mousse, et la mousse présente ainsi une rigidité naturelle facilitant un enroulement homogène. Alternativement, le corps 2 peut également être réalisé dans une mousse à cellules ouvertes ou semi-ouvertes, et ainsi être apte à absorber et à retenir du produit au contact de la mèche.For example, they can be made respectively of foam, by polyvinyl chloride (PVC) foam, polyurethane foam, polyether, polyester, or an elastomer of the type of natural rubbers (NBR) or synthetic (SBR), butyl rubber, silicone, nitrile, EPDM (copolymer of a diene with ethylene and propylene) and comprises preferably at least 10% of open cells. According to a first mode of embodiment, the body 2 is made of a closed cell foam. So of product can not soak in the foam, and the foam thus presents a natural rigidity facilitating a homogeneous winding. Alternatively, the body 2 can also be performed in an open-cell or semi-open cell foam, and thus be able to absorb and retain the product in contact with the wick.

Dans le cas où le bigoudi 1 est réalisé à partir de panneaux de mousse, les parois estampées présentent une bonne accroche, et permettent une bonne fixation des cheveux qui sont appliqués contre, les cellules de la mousse étant ouvertes à ce niveau. En variante, un mode de découpe différent du panneau, peut conduire à ce que les parois extérieures du bigoudi soient imperméables.In the case where the curler 1 is made from foam panels, the stamped walls have a good grip, and allow a good fixing the hair that is applied against, the cells of the foam being open at this level. Alternatively, a different cutting mode of the panel, can lead to the outer walls of the curler being impervious.

Selon un mode de réalisation particulier présenté Figures 1 à 4b, le pied 3 comporte un pourtour extérieur arrondi, entaillé par la présence de la fente 7. La fente 7 présente son entrée 8 à distance de la jonction avec le corps 2.According to a particular embodiment shown in FIGS. 1 to 4b, the foot 3 has a rounded outer circumference, cut by the presence of the slot 7. slot 7 has its input 8 at a distance from the junction with the body 2.

Selon le mode de réalisation des figures 2 à 4, la fente 7 est définie jusqu'à la zone de jonction J, alors que selon le mode de réalisation de la figure 1, la fente 7 est entièrement définie à distance de cette jonction J. Alternativement, la fente des figures 2 à 4 peut également être intégralement formée à distance de cette jonction J. According to the embodiment of FIGS. 2 to 4, the slot 7 is defined up to the junction zone J, whereas according to the embodiment of FIG. 1, the slot 7 is entirely defined at a distance from this junction J. Alternatively, the slot FIGS. 2 to 4 can also be integrally formed at a distance from this junction J.

Avantageusement, les bords de ce corps 2, définis le long de l'axe longitudinal X, présentent des irrégularités de surface sur au moins une partie de leur longueur respective. Par exemple, le corps 2 comporte au moins une paroi 26 crantée, et de préférence au moins deux parois crantées 26 et 27, en vis-à-vis l'une de l'autre, comme cela est représenté sur les Figures 2 à 4. L'estampage d'un corps avec un tel profil cranté est aisé et peut être réalisé en une seule étape.Advantageously, the edges of this body 2, defined along the axis longitudinal X, have surface irregularities on at least a part of their respective length. For example, the body 2 comprises at least one wall 26 notched, and preferably at least two notched walls 26 and 27, vis-à-vis from each other, as shown in Figures 2 to 4. Stamping of a body with such a notched profile is easy and can be achieved in one step.

En particulier, le crantage est réalisé de manière régulière et ou de telle sorte q'un renfoncement tel que 28 dans l'une des parois a pour image relativement à l'axe longitudinal X une excroissance telle que 29 dans l'autre des parois en vis-à-vis. Une telle disposition des crans alternés permet la formation d'un filetage grossier. En effet, le corps 2 est de préférence configuré pour permettre un enroulement en hélice du reste de la mèche M2. Le crantage est par exemple tel qu'une distance entre deux excroissances telles que 29 consécutives d'une même paroi est de l'ordre d'un diamètre moyen maximal d'une mèche à enrouler sur un tel bigoudi. Par exemple, cette distance est de l'ordre de 15 mm.In particular, the notching is carried out in a regular manner and or such so that a recess such as 28 in one of the walls has a picture relative to the longitudinal axis X an outgrowth such as 29 in the other of the walls in vis-à-vis. Such an arrangement of alternating notches allows training a coarse thread. Indeed, the body 2 is preferably configured to allow a spiral winding of the rest of the wick M2. The notching is by example such as a distance between two outgrowths such as 29 consecutive of the same wall is of the order of a maximum average diameter of a wick to wrap on such a curler. For example, this distance is of the order of 15 mm.

En variante, le corps 2 peut présenter un filetage au niveau de son pourtour extérieur pour faciliter cet enroulement en hélice.Alternatively, the body 2 may have a thread at its periphery outside to facilitate this winding helix.

La mèche peut ainsi être enroulée en hélice autour du corps 2. Le pas d'enroulement peut être continu ou variable, et plus ou moins serré dans la mesure où le crantage du corps 2 permet de choisir entre un enroulement serré sans espace entre les crans ou a contrario plus lâche comme cela est représenté Figure 1.The wick can thus be wound helically around the body 2. The pitch winding can be continuous or variable, and more or less tight in the measure where the detent of the body 2 allows to choose between a tight winding without space between the notches or a looser counterpart as shown Figure 1.

Un tel enroulement en hélice de la mèche autour du corps 2 conduit à disposer des boucles de plus en plus éloignées de la première extrémité 9. A la fin de l'enroulement, on entoure de manière préférentielle la pointe P de la mèche M dans un matériau tel que par exemple une feuille de papier aluminium ou de papier pointes, et ensuite on bloque cette pointe P au moyen d'un rabat 10 du corps 2. Such a spiral winding of the wick around the body 2 leads to have loops further and further away from the first end 9. At the end of the winding, the tip P of the wick M is preferably surrounded by in a material such as, for example, a sheet of aluminum foil or paper points, and then we block this tip P by means of a flap 10 of body 2.

Le rabat 10 est formé à une seconde extrémité axiale 11 opposée à la première extrémité 9 relativement à l'axe longitudinal X. Le rabat 10 est configuré pour pouvoir occuper une première position dans laquelle l'enroulement est permis et une seconde position dans laquelle le rabat occupe relativement à une partie intermédiaire du corps 2 située entre les deux extrémités 9 et 11 et autour de laquelle est réalisée l'enroulement de la mèche, une position permettant le blocage d'une portion de cette mèche entre ledit rabat 10 et ladite partie intermédiaire du corps 2. Entre les extrémités 9 et 11, le corps présente le long de l'axe longitudinal X, une partie dite « intermédiaire » autour de laquelle la mèche est enroulée, cette partie intermédiaire étant située à proximité de la première extrémité 9, et une partie formant ledit rabat 10 située à proximité de la seconde extrémité 11.The flap 10 is formed at a second axial end 11 opposite to the first end 9 relative to the longitudinal axis X. The flap 10 is configured to be able to occupy a first position in which the winding is allowed and a second position in which the flap occupies relatively to a intermediate part of the body 2 located between the two ends 9 and 11 and around of which is made the winding of the wick, a position allowing the blocking a portion of this wick between said flap 10 and said portion intermediate body 2. Between the ends 9 and 11, the body presents along the longitudinal axis X, a so-called "intermediate" part around which the wick is wound, this intermediate part being located near the first end 9, and a portion forming said flap 10 located near the second end 11.

Ce rabat 10 est initialement profilé, dans une première position, de telle sorte qu'un axe d'allongement principal du rabat se superpose à l'axe longitudinal X. Notamment lorsque le corps 2 est réalisé dans un matériau élastiquement déformable, pour maintenir la position du rabat 10 dans une position de blocage de la mèche M, le corps 2 comporte un raidisseur 12 déformable de manière semi permanente, ce raidisseur 12 n'étant pas à mémoire de forme. Ainsi lorsque le corps 2, et en particulier la partie formant le rabat 10, sont contraints dans une deuxième position, cette deuxième position est alors maintenue par la présence de ce raidisseur, une portion de la mèche M pouvant ainsi être maintenue par serrage entre la partie intermédiaire du corps et ce rabat 10.This flap 10 is initially profiled, in a first position, of such so that a main axis of elongation of the flap is superimposed on the longitudinal axis X. In particular when the body 2 is made of an elastic material deformable, to maintain the position of the flap 10 in a blocking position of the wick M, the body 2 comprises a semi-deformable stiffener 12 semi permanent, this stiffener 12 is not in shape memory. So when the body 2, and in particular the portion forming the flap 10, are constrained in a second position, this second position is then maintained by the presence of this stiffener, a portion of the lock M can thus be maintained by tightening between the intermediate part of the body and this flap 10.

Dans l'exemple représenté, le raidisseur 12 est un fil de cuivre s'allongeant le long de l'axe longitudinal X au travers du corps 2. Le fil de cuivre est par exemple retenu par un point de colle dans le corps 2. De préférence, ce fil est de longueur inférieure à la longueur du corps 2 de manière à ce qu'il ne dépasse pas de manière visible du pourtour extérieur du corps.In the example shown, the stiffener 12 is an elongated copper wire along the longitudinal axis X through the body 2. The copper wire is example retained by a point of glue in the body 2. Preferably, this thread is of length less than the length of the body 2 so that it does not exceed visibly from the outer circumference of the body.

En particulier, pour bloquer la pointe P, on déplace le rabat 10 en lui faisant faire une rotation de 180° au niveau d'un point de pliure 30, sensiblement proche du niveau où se situe la pointe P sur le corps 2. Le point de pliure 30 qui peut être choisi à volonté le long de l'axe longitudinal X délimite la partie intermédiaire autour de laquelle la mèche est enroulée de la partie formant le rabat 10.In particular, to block the tip P, we move the flap 10 by making him rotate 180 ° at a fold point 30, substantially close the level where the point P is on the body 2. The folding point 30 which can be chosen at will along the longitudinal axis X delimits the intermediate part around which the wick is wound from the portion forming the flap 10.

Dans le cas où l'utilisatrice a les cheveux courts, il est possible exercer cette pliure dans la zone crantée 31 du corps 2. Par contre si l'utilisatrice a les cheveux suffisamment longs pour être enroulés jusqu'au dernier cran de cette zone crantée 31, alors la pliure est réalisée à la limite entre la zone crantée 31 et la zone non crantée 32.In the case where the user has short hair, it is possible to exercise this fold in the notched zone 31 of the body 2. On the other hand, if the user has the hair long enough to be rolled up to the last notch of this toothed zone 31, then the fold is made at the boundary between the notched zone 31 and the notched area 32.

En particulier, la zone crantée 31 du corps 2 représente les deux tiers de la longueur du corps 2 relativement à l'axe longitudinal X, et la zone non crantée 32 forme le dernier tiers de la longueur de ce corps 2. En variante, le corps 2 peut être totalement cranté ou pas cranté du tout, toutes autres répartitions des zones crantées et non crantées entrant également dans le cadre de la présente invention.In particular, the notched zone 31 of the body 2 represents two thirds of the length of the body 2 relative to the longitudinal axis X, and the notched zone 32 form the last third of the length of this body 2. Alternatively, the body 2 can be totally notched or not notched at all, all other areas notched and not notched also within the scope of this invention.

A la fin du temps de mise en plis des cheveux, dès que le produit appliqué sur les mèches de cheveux ainsi enroulées a réalisé sous effet, le bigoudi 1 est retiré en écartant le rabat 10 de sa deuxième position de manière à libérer la pointe P. On défait ensuite l'enroulement de la portion M2 et on dégage enfin la portion M1 du pied 3. Le rabat 10 peut alors être placé dans une troisième position différente de la première position, tel qu'il ne s'étend plus dans le prolongement de l'axe longitudinal de la partie du corps 2 destinée à recevoir l'enroulement des mèches.At the end of the hair setting time, as soon as the applied product on the locks of hair thus wrapped realized under effect, the hair curler 1 is removed by removing the flap 10 from its second position so as to release the point P. Then the winding of the portion M2 is undone and finally the portion M1 of the foot 3. The flap 10 can then be placed in a third position different from the first position, as it no longer extends as an extension of the longitudinal axis of the part of the body 2 intended to receive the winding of the wicks.

Selon une variante de réalisation, le pied 3 dépasse d'un seul côté du corps 2. En variante, le pied 3 peut également dépasser d'un deuxième côté de ce corps 2, et de préférence de manière à proposer une plus grande surface d'appui sur le crâne. Parallèlement, et dans ce dernier cas, le pied 3 peut présenter une deuxième fente apte à recevoir une deuxième mèche, cette deuxième mèche étant également entourée autour du corps 2. Etant donné l'objet de l'invention, notamment pour les mèches définies de part et d'autre d'une raie formée sur le dessus de la tête, un seul bigoudi peut alors être utilisé pour enrouler deux mèches. Dans ce cas, moins de bigoudis selon l'invention sont nécessaires pour traiter l'ensemble d'une chevelure. En variante encore, un même bigoudi peut servir à enrouler deux voire plusieurs mèches en présentant autant de fentes que nécessaire, ces fentes étant orientées dans des directions adaptées. Le cas échéant, le crantage est alors également adapté pour recevoir l'enroulement d'autant de mèches correspondantes.According to an alternative embodiment, the foot 3 protrudes from one side of the body 2. Alternatively, the foot 3 may also protrude from a second side of this body 2, and preferably so as to provide a greater bearing surface on the skull. In parallel, and in the latter case, the foot 3 may have a second slot adapted to receive a second wick, this second wick being also surrounded around the body 2. Given the object of the invention, particular for the wicks defined on either side of a line formed on the above the head, a single curler can then be used to wrap two wicks. In this case, fewer curlers according to the invention are necessary for treat all of a hair. As a variant again, the same curler may used to wrap two or more locks with as many slots as necessary, these slots being oriented in adapted directions. The case where appropriate, the notching is then also adapted to receive the winding correspondingly many locks.

En variante encore, même si le pied 3 ne dépasse que d'un seul côté du corps 2, elle peut également présenter plusieurs fentes telles que 7 pour recevoir respectivement différentes mèches juxtaposées. Ces fentes peuvent être radialement convergentes vers l'axe longitudinal X du corps 2.In another variant, even if the foot 3 only protrudes from one side of the body 2, it may also have several slots such as 7 to receive respectively different locks juxtaposed. These slots can be radially convergent towards the longitudinal axis X of the body 2.

Dans toute la description, l'expression « comportant un » doit être considérée comme étant synonyme de « comportant au moins un », sauf si le contraire est spécifié.Throughout the description, the phrase "with one" must be considered to be synonymous with "having at least one" unless the opposite is specified.
