Abstract

The depilator has a curved prestressed helical spring mounted rotatively on a case. A motor is coupled to the spring to drive the spring in a rotational movement for a tangential movement of the spring relative to skin to be epilated by creating continuous movement of spires of the spring from a spacing orientation to a compression orientation. The spires are made from rectangular, square or trapezoidal wire (2). The spring forms a divergent zone and a convergent compression zone, in which the spires are spaced and pressed against each other, respectively to grip and remove hair from the skin.

Description

Objet de l'inventionObject of the invention

La présente invention se rapporte à un épilateur et plus particulièrement à un épilateur comportant un ressort hélicoïdal réalisé à partir d'un fil à section rectangulaire, carrée ou trapézoïdale.The present invention relates to an epilator and more particularly to an epilator comprising a helical spring made from a rectangular, square or trapezoidal wire.

Etat de la techniqueState of the art

L'homme de métier connaît bien les dispositifs d'épilation comportant un ressort hélicoïdal qui fonctionne selon le principe du pincement des poils entre les spires du ressort lorsque celui-ci est courbé et forme une zone de compression sur un côté. Ce genre de dispositif est généralement équipé d'un moteur qui entraîne le ressort hélicoïdal dans un mouvement de rotation permettant alternativement de comprimer et d'allonger les spires du ressort dans une position courbée, le ressort étant entrainé en rotation par un moteur. Ce type de dispositif est notamment divulgué dans les documents US-A-4,524,772 ainsi que FR-2 627 362 .Those skilled in the art are well acquainted with depilatory devices comprising a helical spring which operates according to the principle of pinching the bristles between the turns of the spring when the latter is bent and forms a compression zone on one side. This type of device is generally equipped with a motor that drives the helical spring in a rotational movement that alternately compresses and lengthens the turns of the spring in a curved position, the spring being rotated by a motor. This type of device is notably disclosed in the documents US Patent 4,524,772 as well as FR-2 627 362 .

Un ressort hélicoïdal est classiquement réalisé à partir d'un fil à section circulaire. La force de ce ressort est donc essentiellement conditionnée par le matériau utilisé et par le diamètre du fil avec lequel il est réalisé ; par ailleurs, la distance entre les surfaces ou les points de pincement qui sont en fait le lieu de contact entre deux spires adjacentes et la peau est également déterminée par le diamètre du fil (voir fig. 3). Autrement dit, plus le diamètre du fil est élevé, plus la distance de pincement par rapport à la peau est grande, et plus l'épilation est douloureuse.A helical spring is conventionally made from a circular section wire. The force of this spring is therefore essentially conditioned by the material used and the diameter of the wire with which it is made; furthermore, the distance between the surfaces or pinch points which are in fact the contact point between two adjacent turns and the skin is also determined by the diameter of the wire (see Fig. 3). In other words, the higher the diameter of the wire, the greater the pinch distance from the skin is large, and more hair removal is painful.

Lorsque l'on veut donc modifier la force du ressort, on est obligé d'augmenter le diamètre du fil, ce qui a pour conséquence d'augmenter également la distance de pincement du poil par rapport à la peau, ce qui est un effet non désiré.When it is therefore desired to modify the spring force, it is necessary to increase the diameter of the wire, which has the consequence of also increasing the niping distance of the hair relative to the skin, which is a no effect. longed for.

Buts de l'inventionGoals of the invention

La présente invention vise à fournir un dispositif d'épilation à ressort hélicoïdal dont la force du ressort est indépendante de la distance de pincement par rapport à la peau et dont la section du fil est telle qu'il permet un pincement des pois au plus près de la peauThe present invention aims to provide a coil spring hair removal device whose spring force is independent of the nip distance from the skin and whose section of the wire is such that it allows a pinch of the peas as close as possible skin

La présente invention divulgue un épilateur comportant un boitier et un ressort hélicoïdal précontraint en configuration courbée et monté de manière rotative sur ledit boitier, ainsi qu'un moteur couplé audit ressort destiné à entrainer le ressort, lors de l'utilisation de l'épilateur, dans un mouvement de rotation, conférant audit ressort un mouvement tangentiel par rapport à la peau à épiler en engendrant un mouvement continu desdites spires, d'une orientation d'écartement à une orientation de compression caractérisé en ce que ledit ressort hélicoïdal possède des spires réalisées à partir d'un fil à section essentiellement rectangulaire, carrée ou trapézoïdale ledit ressort formant à l'état précontraint une zone divergente où les spires sont écartées les unes des autres et une zone de compression convergente où les spires sont pressés les unes contre les autres pour la prise et l'enlèvement des poils de la peau.The present invention discloses an epilator comprising a casing and a helical spring prestressed in curved configuration and rotatably mounted on said housing, and a motor coupled to said spring for driving the spring, when using the epilator, in a rotational movement, imparting to said spring a tangential movement with respect to the skin to be epilated by generating a continuous movement of said turns from a spacing orientation to a compression orientation characterized in that said coil spring has turns made from a wire of substantially rectangular, square or trapezoidal section, said spring forming in the prestressed state a diverging zone where the turns are spaced from each other and a convergent compression zone where the turns are pressed against each other for taking and removing hair from the skin.

Dans un mode d'exécution préféré de l'invention, lesdites spires comportent des encoches pour peigner les poils à épiler.In a preferred embodiment of the invention, said turns comprise notches for combing the depilatory hairs.

Brève description des figuresBrief description of the figures

La figure 1 représente le ressort hélicoïdal fabriqué à partir d'un fil à section essentiellement rectangulaire. Les sections carrées et trapézoïdales ne sont pas représentées. Des encoches sont également représentées en détail sur la loupe de cette figure.Figure 1 shows the coil spring made from a wire of substantially rectangular section. The square and trapezoidal sections are not represented. Notches are also shown in detail on the magnifying glass of this figure.

La figure 2 représente plusieurs vues du ressort d'épilation monté rotatif sur son support. La présence du moteur y est représentée schématiquement dans le boitier. Le détail des zones divergentes et convergentes y est relevé.Figure 2 shows several views of the epilation spring rotatably mounted on its support. The presence of the motor is schematically represented in the case. The details of the divergent and convergent zones are noted.

La figure 3 représente un ressort d'épilation à section ronde selon l'état de la technique ou il subsiste une distance indésirable entre le point de pincement et la peau.Figure 3 shows a hair removal spring with round section according to the state of the art or there is an undesirable distance between the pinch point and the skin.

La figure 4 représente le pincement du poil avec le ressort hélicoïdal avec fil à section essentiellement rectangulaire de l'invention (coins légèrement arrondis dus aux contraintes de fabrication) qui permet de pincer le poil sur une grande surface de pinçage, c'est-à-dire sur une surface plus grande que celles présentées par les ressorts obtenus à partir de fils ronds de l'état de la technique (voir fig. 4) et à ras de la peau. Des sections carrées ou trapézoïdales produisent le même effet. Les sections trapézoïdales permettent même de réaliser une surface de pincement reprenant intégralement la hauteur de la section de la spire selon la courbure de précontrainte qui est donnée au ressort.FIG. 4 shows the pinching of the pile with the helical spring with wire of essentially rectangular section of the invention (slightly rounded corners due to manufacturing constraints) which makes it possible to pinch the pile over a large pinching surface, that is to say on a larger surface than those presented by the springs obtained from round wires of the state of the art (see Fig. 4) and flush with the skin. Square or trapezoidal sections produce the same effect. The trapezoidal sections even make it possible to achieve a gripping surface wholly taking up the height of the section of the turn according to the prestressing curvature which is given to the spring.

Description détaillée de l'inventionDetailed description of the invention

La présente invention divulgue un nouveau dispositif d'épilation basé sur un élément d'épilation à ressort hélicoïdal 1 dans lequel on a remplacé le ressort fabriqué avec un fil à section ronde par un ressort réalisé à partir d'un fil à section essentiellement rectangulaire 2 ou carrée. Nous entendons par essentiellement rectangulaire ou carrée, un rectangle ou un carré avec des coins légèrement arrondis. Ces coins arrondis sont évidemment dus à des contraintes de fabrication car il n'est pas souhaitable d'avoir un fil avec une section rectangulaire à bord coupant. Le mot rectangulaire ne doit donc pas être interprété au sens strictement géométrique du terme.The present invention discloses a novel hair removal device based on a helical spring hair removal element 1 in which the spring made with a round section wire has been replaced by a spring made from a wire of substantially rectangular section 2 or square. We mean by essentially rectangular or square, a rectangle or a square with slightly rounded corners. These rounded corners are obviously due to manufacturing constraints because it is not desirable to have a wire with a rectangular section with a cutting edge. The rectangular word must not be interpreted in the strictly geometric sense of the term.

Le ressort 1 réalisé à partir d'un fil à section rectangulaire, carrée ou trapézoïdale 2 permet de découpler la force du ressort 1 de la distance de pincement par rapport à la peau 8 en ce sens que l'on peut obtenir des ressorts puissants capables de pincer un poil 9 directement à la racine et au contact immédiat avec la peau 8. Les géométries des fils à section rectangulaire, carrée ou trapézoïdale 2 forment des spires sur un ressort hélicoïdal qui ont une position essentiellement perpendiculaire à la peau, sachant que le pinçage se réalise au niveau de la largeur externe de la section du fil servant à réaliser le ressort.The spring 1 made from a wire with a rectangular, square or trapezoidal section 2 makes it possible to decouple the force of the spring 1 from the pinch distance with respect to the skin 8 in the sense that it is possible to obtain powerful springs capable of to pinch a hair 9 directly at the root and in immediate contact with the skin 8. The geometries of the rectangular, square or trapezoidal wire 2 form turns on a helical spring which have a position essentially perpendicular to the skin, knowing that the pinching is carried out at the outer width of the section of the wire used to make the spring.

Pour jouer sur la force du ressort, on peut faire varier plusieurs paramètres, à savoir le diamètre de la spire, la hauteur du rectangle/carré/trapèze qui constitue la section du fil, la largeur extérieure et/ou intérieure et la nature du matériau.To play on the force of the spring, it is possible to vary several parameters, namely the diameter of the turn, the height of the rectangle / square / trapezium which constitutes the section of the wire, the outer and / or inner width and the nature of the material. .

Ces trois paramètres permettent donc de réaliser un ressort sur mesure dont la force n'influence en aucune manière la distance de pincement par rapport à la peau contrairement aux ressorts à section ronde de l'état de la technique (voir fig. 3 et 4).These three parameters therefore make it possible to produce a tailor-made spring, the force of which in no way influences the pinch distance with respect to the skin, unlike the round-section springs of the state of the art (see Figs 3 and 4). .

Les ressorts peuvent être pliés de différentes manières, comme le montre notamment le document FR-2 627 362 ou encore le document EP-B1-0 101 656 .The springs can be folded in different ways, as shown in particular in the document FR-2 627 362 or the document EP-B1-0 101 656 .

Le fait d'utiliser un ressort à section rectangulaire/carrée pour l'élément d'épilation permet également d'intégrer dans les spires 2 dudit élément des encoches 5 plus ou moins profondes permettant de peigner le poil 9 avant son épilation (voir fig. 1). Ce type d'encoches était également impossible à réaliser sur un ressort hélicoïdal réalisé à partir d'un fil à section ronde.The fact of using a rectangular / square section spring for the hair removal element also makes it possible to integrate in the turns 2 of said element notches 5 of greater or lesser depth to comb the hair 9 before hair removal (see FIG. 1). This type of notches was also impossible to achieve on a helical spring made from a round section wire.

Pour des raisons d'hygiène et de facilité de nettoyage, ce type de ressort est généralement réalisé en acier inoxydable ou dans une autre manière non-susceptible de s'oxyder.For reasons of hygiene and ease of cleaning, this type of spring is usually made of stainless steel or in another way not likely to oxidize.
