Description

Objet de l'inventionSubject of the invention

La présente invention se rapporte à un sèche-cheveux comprenant un dispositif pour ranger le câble d'alimentation par enroulement de celui-ci autour du sèche-cheveux.The present invention relates to a hair dryer comprising a device for storing the power cable by winding it around the hair dryer.

Etat de la techniqueState of the art

Les sèche-cheveux sont équipés d'un câble d'alimentation électrique généralement assez long. Après utilisation, l'utilisateur enroule généralement le cordon d'alimentation simplement autour du boitier du sèche-cheveux pour le ranger. Cependant, si le câble n'est pas maintenu par un quelconque dispositif, il peut se détacher et glisser du boîtier du sèche-cheveux. Il existe donc des systèmes permettant de maintenir le cordon sur le sèche-cheveux une fois qu'il est enroulé autour de celui-ci.Hair dryers are equipped with a power cord that is usually quite long. After use, the user usually simply wraps the power cord around the hair dryer housing to store it. However, if the cord is not held by some device, it can detach and slip out of the hair dryer housing. There are therefore systems to keep the cord on the hair dryer once it is wrapped around it.

Le document CN104621947 divulgue un sèche-cheveux comprenant une rainure d'enroulement sur la partie arrière de son boitier. L'utilisateur peut enrouler le cordon d'alimentation en le faisant passer dans la rainure afin qu'il y soit retenu. Cependant, comme l'enroulement se fait uniquement autour du boitier du sèche-cheveux, de nombreuses boucles sont nécessaires avant que le câble ne soit complètement enroulé.The document CN104621947 discloses a hair dryer having a winding groove on the rear portion of its housing. The user can wind the power cord by passing it through the groove so that it is retained therein. However, since the winding is done only around the housing of the hair dryer, many loops are necessary before the cord is completely wound.

Le document DE9114815 illustre un sèche-cheveux qui comporte un dispositif d'enroulement du cordon d'alimentation permettant d'enrouler le cordon sur toute la hauteur du sèche-cheveux, à savoir entre le boitier du sèche-cheveux et le bas de la poignée. Pour ce faire, la partie distale de la poignée comprend un évidement de réception en forme de creux pour y faire passer le câble, et le boitier du sèche-cheveux comprend une protubérance pour permettre de centrer le câble et éviter qu'il ne glisse du boitier.The document DE9114815 illustrates a hair dryer that includes a cord winding device for winding the cord over the entire height of the hair dryer, namely between the hair dryer housing and the bottom of the handle. To achieve this, the distal portion of the handle includes a hollow-shaped receiving recess for passing the cable therethrough, and the hair dryer housing includes a protrusion to center the cable and prevent it from slipping off the housing.

Le document EP1151690A2 divulgue un sèche-cheveux comprenant un dispositif pour ranger le cordon d'alimentation de manière compacte sur le sèche-cheveux. Le cordon est rangé par l'enroulement de celui-ci autour de deux surfaces de contact, correspondant d'une part au boitier du sèche-cheveux et d'autre part au manchon de protection du cordon situé à la base de la poignée du sèche-cheveux. Les surfaces de contact sont pourvues d'indentations dans lesquelles viennent s'insérer le cordon afin d'être maintenu.The document EP1151690A2 discloses a hair dryer comprising a device for storing the power cord compactly on the hair dryer. The cord is stored by winding it around two contact surfaces, corresponding on the one hand to the housing of the hair dryer and on the other hand to the cord protection sleeve located at the base of the handle of the hair dryer. The contact surfaces are provided with indentations into which the cord is inserted in order to be held.

Le document DE3501161 décrit un sèche-cheveux comprenant un support pour l'enroulement du cordon d'alimentation. Le support est situé sur la partie inférieure de la poignée, et peut pivoter entre une position d'alignement avec la poignée et une position perpendiculaire à la poignée. L'utilisateur peut placer le support perpendiculairement à la poignée afin d'enrouler le cordon entre ce support et le boitier du sèche-cheveux.The document DE3501161 describes a hair dryer comprising a holder for winding the power cord. The holder is located on the lower portion of the handle, and is pivotable between a position aligned with the handle and a position perpendicular to the handle. The user can position the holder perpendicular to the handle in order to wind the cord between the holder and the housing of the hair dryer.

Lorsque le câble est enroulé autour du sèche-cheveux, son rayon de courbure à la sortie de la poignée est très petit. Cette pliure du cordon l'use petit à petit. Ceci représente une des causes premières des retours des sèche-cheveux aux fabricants pour endommagement.When the cord is wrapped around the hair dryer, its bend radius as it exits the handle is very small. This bending of the cord gradually wears it out. This is one of the primary causes of hair dryers being returned to manufacturers due to damage.

Buts de l'inventionAims of the invention

La présente invention vise à surmonter les inconvénients de l'état de la technique, et en particulier à fournir un sèche-cheveux avec un rangement efficace du cordon d'alimentation, par enroulement du cordon autour du sèche-cheveux. L'invention permet de maintenir le cordon une fois qu'il est placé dans sa position de rangement et d'éviter qu'il ne glisse du boitier.The present invention aims to overcome the disadvantages of the prior art, and in particular to provide a hair dryer with efficient storage of the power cord, by winding the cord around the hair dryer. The invention makes it possible to hold the cord once it is placed in its storage position and to prevent it from slipping out of the housing.

Un autre but de l'invention est de fournir une solution qui évite l'endommagement du cordon à la sortie du sèche-cheveux, grâce à la présence d'un embout de protection mobile.Another aim of the invention is to provide a solution which prevents damage to the cord at the outlet of the hair dryer, thanks to the presence of a movable protective tip.

Un autre but de l'invention est de faciliter la manipulation du sèche-cheveux lors de l'utilisation, grâce à la mobilité de l'embout de protection du cordon à la sortie de la poignée, permettant une meilleure flexibilité lors des mouvements du cordon à la sortie du sèche-cheveux.Another aim of the invention is to facilitate the handling of the hair dryer during use, thanks to the mobility of the cord protection tip at the outlet of the handle, allowing greater flexibility during movements of the cord at the outlet of the hair dryer.

Un autre but de l'invention est de permettre un rangement plus compact du sèche-cheveux grâce à la mobilité de l'embout de protection qui est replié sensiblement perpendiculairement à la poignée et évite d'avoir une longueur supplémentaire en dessous de la poignée.Another aim of the invention is to allow more compact storage of the hair dryer thanks to the mobility of the protective tip which is folded substantially perpendicular to the handle and avoids having additional length below the handle.

Description détaillée de l'inventionDetailed description of the invention

Un exemple de sèche-cheveux selon l'invention est illustré à la Figure 1. Celui-ci comprend un boitier 2 muni d'une poignée 3. Comme tous les sèche-cheveux sans batterie, il est muni d'un cordon d'alimentation 4 sortant du sèche-cheveux par un orifice 7 situé à l'extrémité inférieure de la poignée.An example of a hair dryer according to the invention is illustrated in Figure 1 . This comprises a housing 2 fitted with a handle 3. Like all hair dryers without a battery, it is fitted with a power cord 4 exiting the hair dryer through an opening 7 located at the lower end of the handle.

Le sèche-cheveux de la présente invention comprend un dispositif pour ranger le cordon d'alimentation après utilisation, permettant l'enroulement du cordon autour du sèche-cheveux. Plus précisément, il comporte un logement 6 formé dans la partie supérieure du boitier du sèche-cheveux et un embout de protection mobile 5 du cordon d'alimentation est prévu à la sortie du sèche-cheveux. L'embout de protection peut être déplacé entre une position d'alignement avec la poignée, tel que représenté sur la Figure 1, et une position de rangement dans laquelle l'embout mobile est positionné approximativement perpendiculairement à la poignée, tel que représenté sur les Figures 2 et 4.The hair dryer of the present invention comprises a device for storing the power cord after use, allowing the cord to be wound around the hair dryer. More specifically, it comprises a housing 6 formed in the upper part of the housing of the hair dryer and a movable protective tip 5 of the power cord is provided at the outlet of the hair dryer. The protective tip can be moved between a position of alignment with the handle, as shown in the Figure 1 , and a storage position in which the movable tip is positioned approximately perpendicular to the handle, as shown in the Figures 2 And 4 .

Comme représenté sur la Figure 2, lorsque l'utilisateur désire ranger le sèche-cheveux, il peut enrouler le cordon d'alimentation autour du boitier du sèche-cheveux et de l'embout de protection placé en position de rangement. De cette manière, l'embout a une fonction de maintien du câble d'alimentation. Au niveau du boitier, chaque boucle du cordon est placée dans le logement prévu à cet effet, afin de maintenir le cordon sur le boitier. Le logement de maintien est en fait un renfoncement réalisé dans le boitier, qui a préférablement une longueur comprise entre 3,5 et 5,5 cm, de préférence entre 4 et 5 cm et une profondeur comprise entre 0.7 et 1.3 cm, de préférence entre 0.8 et 1.2 cm.As shown in the Figure 2 , when the user wants to store the hair dryer, he can wrap the power cord around the housing of the hair dryer and the protective tip placed in the storage position. In this way, the tip has a function of holding the power cable. At the housing, each loop of the cord is placed in the housing provided for this purpose, in order to hold the cord on the housing. The holding housing is in fact a recess made in the housing, which preferably has a length of between 3.5 and 5.5 cm, preferably between 4 and 5 cm and a depth of between 0.7 and 1.3 cm, preferably between 0.8 and 1.2 cm.

La taille des boucles formées par le cordon autour du sèche-cheveux sont maximisées grâce au dispositif de l'invention, ce qui permet de limiter le nombre de tours à effectuer pour ranger l'entièreté du cordon. La distance que parcourt le cordon entre l'embout de protection et le logement de maintien est de préférence supérieur à 23 cm, de préférence encore supérieur à 24 cm. Par ailleurs, étant donné que l'embout de protection est mobile, le rayon de courbure du cordon à la sortie de la poignée est augmenté ce qui évite son endommagement.The size of the loops formed by the cord around the hair dryer are maximized by the device of the invention, which makes it possible to limit the number of turns to be made to store the entire cord. The distance traveled by the cord between the protective tip and the holding housing is preferably greater than 23 cm, more preferably greater than 24 cm. Furthermore, since the protective tip is movable, the radius of curvature of the cord at the outlet of the handle is increased, which prevents it from being damaged.

L'embout de protection mobile est représenté plus en détails sur les figures 5 et 6. L'embout de protection est situé du côté distal de la poignée et traverse l'orifice 7 situé à l'extrémité de la poignée. De cette manière, l'embout comprend une partie interne 8 à la poignée et une partie externe 9 à la poignée. La partie interne 8 est sous forme de coque semi-sphérique et se prolonge par la partie externe 9 sous forme tubulaire. Le cordon comprend une première partie interne au sèche-cheveux qui alimente les éléments électriques tels que le moteur, et une seconde partie externe au sèche-cheveux qui permet de se raccorder sur le secteur. L'embout de protection permet de protéger le cordon lors de son passage à l'extérieur de la poignée, le cordon étant localement logé à l'intérieur de l'embout.The movable protective tip is shown in more detail on the figures 5 And 6 . The protective tip is located on the distal side of the handle and passes through the hole 7 located at the end of the handle. In this way, the tip comprises an internal part 8 to the handle and an external part 9 to the handle. The internal part 8 is in the form of a semi-spherical shell and is extended by the external part 9 in tubular form. The cord comprises a first part internal to the hair dryer which powers the electrical elements such as the motor, and a second part external to the hair dryer which allows it to be connected to the mains. The protective tip protects the cord as it passes outside the handle, the cord being locally housed inside the tip.

La partie interne de l'embout sous forme de coque semi-sphérique est de préférence formée de deux quart de sphères creuses fixées à l'aide de deux vis. Les piliers des deux vis 10 encadrent le cordon d'alimentation pour le canaliser à l'intérieur de la coque semi-sphérique.The inner part of the tip in the form of a semi-spherical shell is preferably formed of two hollow quarter spheres fixed using two screws. The pillars of the two screws 10 frame the power cord to channel it inside the semi-spherical shell.

L'embout de protection est mobile et peut pivoter autour d'un axe 11 situé au centre de la partie interne semi-sphérique, comme représenté sur la figure 7. De cette manière, la partie interne semi-sphérique peut pivoter autour de cet axe, ce qui permet à la partie externe tubulaire de passer d'une position d'alignement avec la poignée, tel que représenté sur la Figure 5 à une position de rangement dans laquelle la partie externe est approximativement perpendiculairement à la poignée, tel que représenté sur la Figure 6.The protective tip is movable and can pivot around an axis 11 located at the center of the semi-spherical internal part, as shown in the figure 7 . In this way, the semi-spherical inner part can pivot about this axis, which allows the tubular outer part to move from a position of alignment with the handle, as shown in the Figure 5 to a storage position in which the outer portion is approximately perpendicular to the handle, as shown in the Figure 6 .

Grâce à son maintien à l'intérieur de l'embout de protection mobile, le cordon dans la partie distale de la poignée a un rayon de courbure d'au moins 0.8 cm, préférablement au moins 1 cm, de manière encore préférée d'au moins 1.2 cm. La mobilité de l'embout de protection permet également une meilleure flexibilité d'utilisation due à la mobilité du cordon près de la poignée, sans l'abîmer. L'utilisateur doit faire moins attention lors de l'utilisation et le cordon est un peu épargné des nombreux mouvements.By being held inside the movable protective tip, the cord in the distal part of the handle has a bending radius of at least 0.8 cm, preferably at least 1 cm, more preferably at least 1.2 cm. The mobility of the protective tip also allows for greater flexibility of use due to the mobility of the cord near the handle, without damaging it. The user has to be less careful during use and the cord is somewhat spared from the many movements.

Lorsque l'embout de protection est en position de rangement, la partie semi-sphérique est positionnée de telle manière à fermer l'orifice situé à l'extrémité de la poignée pour que la poignée reste hermétique. Dans cette position, l'orifice fait office de logement pour l'embout de protection. Comme représenté sur les figures 8 et 9, l'orifice de sortie du cordon a une forme spécifique permettant à l'embout de protection de passer de la position d'alignement par rapport à la poignée à la position de rangement dans laquelle l'embout est perpendiculaire à la poignée. L'orifice est donc situé en partie dans la base de la poignée mais également en partie sur un côté latéral de la poignée afin que l'embout de protection puisse traverser la poignée latéralement pour être positionné en position de rangement.When the protective cap is in the storage position, the semi-spherical portion is positioned so as to close the hole located at the end of the handle so that the handle remains sealed. In this position, the hole acts as a housing for the protective cap. As shown in the Figures 8 And 9 , the cord outlet hole has a specific shape allowing the protective tip to move from the aligned position relative to the handle to the storage position in which the tip is perpendicular to the handle. The hole is therefore located partly in the base of the handle but also partly on a lateral side of the handle so that the protective tip can pass through the handle laterally to be positioned in the storage position.
