Description

The present invention relates to devices for use in the hair styling process referred to as "blow drying", "shaping" or "thermobrushing".

Blow drying is a technique of hair drying and shaping well known to hairdressers, which requires the combined action of a hand dryer and a substantially cylindrical hand brush. This styling technique involves working, strand by wick, wet hair using a brush, a comb or fingers, while drying them with a hand dryer.

In this technique, the hairdresser can give volume or curl a hair. To do this, he must take a lock of wet hair each time, wrap it on the hand brush, dry it with a hair dryer and wait for it to cool, so as to obtain a shape determined by the diameter of the brush . Such a process requires the hairdresser to wait for the drying and then the cooling of the wick, before taking a new lock of hair and subjecting it to the same steps of winding, heating, drying and cooling around the brush. . The process is therefore long and tedious, requiring several tens of seconds for the treatment of each strand of hair, resulting in average for a complete head a drying and shaping time of 10 to 20 minutes. We also know the older technique of setting rolls. In this other technique, the hairdresser wraps each strand of wet hair on a roller which he fixes on the hair. After having set and fixed all the rollers, the hairdresser fits a drying helmet which generally simultaneously dries all the locks. This technique gives better results, but it is much longer than blow drying, and we tend to prefer the brushing for reasons of profitability. The problem proposed by the present invention is to design a device and a method for greatly facilitating the blow-drying, while maintaining the flexibility of use of a hand dryer drying, while also maintaining the flexibility of use of the cylindrical brushes. , by improving the quality of the shaping result of the hair obtained by the blow-drying, and by avoiding the loss of time of drying and cooling of the locks of successive hairs. The object of the invention is also to facilitate the manipulation of the material means allowing the implementation of the blow-drying method, in particular to enable the hairdresser to keep the hair dryer in a hand at all times and to manipulate the hair dryer. other hand the other instruments shaping hair strands. Another object of the invention is possibly to improve the hygiene conditions, by automatic cleaning and disinfection of blow-drying instruments. To achieve these and other objects, the invention provides a device for blow drying hair, comprising a plurality of brushing rollers, at least one removable grip handle which can be attached to one of the brushing rollers, and a storage case having: - a receiving compartment sized to receive and contain said plurality of blow-off rollers, - a receiving compartment bottom wall, - a plurality of stabilizing means, shaped to hold each one of the oriented blow-down rollers along a respective axis substantially vertical and away from the other rollers, - a peripheral wall receiving compartment, - a top cover retractable. Since the storage box contains a plurality of rollers oriented about a substantially vertical axis, the hairdresser can take a first roll with the removable handle, proceed to the treatment of a first lock of hair, remove the handle to leave the roller in place on the first lock of hair, come and take a second roll in the storage box using the removable handle, position the second roll on a second lock of hair, and so on. At the same time, the hairdresser can maneuver the hair dryer to gradually dry the bits arranged on the rollers. It is understood that the operation of the rollers and the handle can be performed with one hand, which frees the other hand for the operation of the hair dryer.

Preferably, the rollers are provided with a first attachment end adapted to be received and removably retained on the distal end of the handle, the handle being provided with locking and unlocking means shaped in such a way that the maneuvers fixing and releasing the roller on the handle can be performed by the single hand holding the handle. In this way, both a good holding of a roll at the end of the grip handle and a handling of the rollers by the single hand holding the grip handle are guaranteed. According to a preferred embodiment, it is provided that: the storage box further comprises a lower compartment, located below said receiving compartment bottom wall, and containing a source of ultraviolet radiation for directing ultraviolet radiation towards the receiving compartment bottom wall, - receiving chamber bottom wall is transparent to ultraviolet radiation, to allow said ultraviolet radiation to enter the receiving compartment. In this way, when the rollers are positioned in the receiving compartment, they can be permanently subjected to ultraviolet radiation which ensures their disinfection, to comply with hygiene regulations.

The invention thus ensures the respect of hygiene conditions, while facilitating the handling of blow-drying tools. Advantageously, it can be provided that: the peripheral wall and the cover of the receiving compartment are provided with a reflective inner surface, the lower compartment comprises a base and a lower peripheral wall, themselves provided with a reflective inner surface. In this way, the reflective interior surfaces concentrate the ultraviolet radiation in order to direct it towards the receiving compartment, avoiding its dispersion towards the outside. This increases the effectiveness of ultraviolet radiation to ensure good disinfection. The stabilizing means may occupy all or part of the bottom wall. In the case where the stabilizing means occupy the entire lower wall of the receiving compartment, the receiving compartment can then receive a maximum number of rollers, which may be of interest for a large capacity for a reduced volume of compartment. reception. In the case where the stabilizing means occupy only part of the bottom wall, the lower wall of the receiving compartment then comprises a surface area devoid of stabilization means, which surface area can be used to store other tools such as as scissors, razors, combs, in order to make them undergo the treatment of disinfection by ultraviolet radiation. 37FDEP.docx 4 In order for the rollers to easily and effectively adopt a vertical position in the receiving compartment, it is advantageous to provide stabilizing means in which: each roll is provided with a second end with an axial catch, - Each stabilizing means comprises a housing adapted to receive and retain the axial lug of a roller. This arrangement further promotes the use of the receiving compartment to store other tools such as combs, scissors or razors, in that these tools can be arranged horizontally on the lower wall of the receiving compartment, even in areas equipped with stabilizing means, since the stabilizing means are housings and do not form protuberances opposing the arrangement of the tools. According to another aspect, the invention proposes a new method of blow drying the hair, consisting in the use of a device as defined above, the receiving compartment of which contains at least one roller, this use comprising the steps of: a ) take the handle, b) open the cover of the storage box, c) attach the brushing roller to the handle, d) remove the roller assembly - handle, e) proceed with the winding a lock of hair around the roller, and subject the wick to a stream of hot air, f) remove the handle away from the roller, which remains in place on the lock of hair, g) after drying and cooling fit the handle on the roller, h) remove the handle assembly - roller, away from the lock of hair, i) insert the roller held by the handle into the receiving compartment, l to engage vertically on one of the stabilizing means, and remove the handle from the receiving compartment. It is understood that during such use, the hairdresser can keep the hair dryer in one hand, and has the other hand to maneuver the removable handle and rollers.

Preferably, during this use, it is provided that: the storage box further comprises a lower compartment, located below said lower wall of the receiving compartment, and containing a source of ultraviolet radiation for directing a ultraviolet radiation to the lower wall of the receiving compartment, the lower wall of the receiving compartment is transparent to ultraviolet radiation, to allow said ultraviolet radiation to penetrate into the receiving compartment, the lid is closed, the source of ultraviolet radiation to subject the roller to ultraviolet radiation. Other objects, features and advantages of the present invention will emerge from the following description of particular embodiments, made with reference to the appended figures, in which: FIG. 1 is a perspective view of a device according to a first embodiment of the present invention, the top cover being ajar, and rollers being placed in the receiving compartment; - Figure 2 is a side view in partial section of a roller and the handle; and FIG. 3 is a sectional side view of a device according to a second embodiment of the present invention. In a first embodiment as illustrated in FIG. 1, the hair-blowing device according to the invention comprises a storage box 1, a plurality of blow-drying rollers such as the roll 2, and at least one handle of 3. The storage case 1 defines a receiving compartment 4, of parallelepipedal shape, and dimensioned to receive and contain said plurality of rollers 2. By way of example, one can provide a receiving compartment 4 having a length L1 d about 30 cm, a width L2 of about 20 cm, and a depth L3 of about 15 cm. The receiving compartment 4 is limited by a peripheral wall 5 receiving compartment, a lower wall 6 receiving compartment, and a top cover 7 retractable, for example articulated on the upper edge of the peripheral wall 5 according to a hinge 8. The lid 7 can pivot around the hinge 8 between a closed position in which it closes the receiving compartment 4, and a retracted position in which it leaves free access to the interior space of the receiving compartment 4 by its opening higher. The lower wall 6 comprises a plurality of stabilization means 9, distributed along the surface of the bottom wall 6, and each shaped to hold a 6-roller 2 and to orient it along a substantially vertical axis II respectively and to away from other rollers. In the advantageous embodiment illustrated in FIG. 1, each stabilizing means 9 comprises a housing adapted to receive and retain an appropriate end portion of a roll 2. As can be seen in FIG. 1, the rollers 2 are vertically oriented, so that their length must be less than the depth L3 of the receiving compartment 4. In practice, therefore, the depth L3 of the receiving compartment 4 is chosen so that it is greater than the length of the rollers 2 that the we want to use, so that the presence of the rollers 2 contained in the receiving compartment 4 does not prevent the closure of the cover 7. We now consider Figure 2, which illustrates in more detail the structure of a roller 2 and its In this embodiment, the roller 2 is a cylindrical tube 2a bearing radially oriented bristles 2b, and having a first fixing end 2c and a e second end 2d storage. In the illustrated embodiment, the first fixing end 2c is cylindrical hollow, defining a second housing adapted to receive and retain an axial lug 3a of the handle 3.

The second end 2d of the roll 2 comprises an axial lug 2f. Each stabilizing means 9 comprises a housing adapted to receive and retain the axial lug 2f of the roller 2 to hold the roller 2 in a substantially vertical position in the receiving compartment 4, as illustrated in FIG. 1. By way of example, the axial lug 2f of the roller 2 and the housing of the stabilizing means 9 may have a cylindrical shape of revolution, the diameter of the housing being slightly greater than the diameter of the axial lug 2f, the axial lengths of the housing and the lug axial 2f being chosen sufficient to ensure the positioning stability of the roller 2. For example, an axial lug 2f having a length of 5 to 10 mm may give good stability.

The handle 3, as shown in Figure 2, comprises locking and unlocking means for selectively ensuring, by a solicitation by the hand of the hairdresser holding the handle 3, the fixing of the roller 2 on the handle 3 or the release of the roller 2 away from the handle 3. For example, the handle 3 may comprise retractable lugs 3b protruding radially from the peripheral surface of the axial lug 3a, retractable by action on a unlocking button 3c, and recalled in the deployed position illustrated in Figure 2 by elastic means. In the deployed position 37FDEP.docx 7, the retractable lugs 3b can engage in locking slots 2g provided in the vicinity of the first fixing end 2c of the roller 2 to ensure the locking of the roller 2 on the handle 3. In the second embodiment as shown in Figure 3, the device according to the invention uses the same means as those illustrated in relation to Figures 1 and 2, and these same means are identified by the same reference numerals. There is thus a storage case 1, rollers 2, a gripping handle 3, a receiving compartment 4, a peripheral wall 5, a bottom wall 6, a cover 7, a hinge 8 and stabilizing means 9. this second embodiment, the device further comprises a lower compartment 10, located below said lower wall 6 of the receiving compartment 4, and containing a source of ultraviolet radiation 11. In this case, it has been illustrated on the Figure 3 two sources of ultraviolet radiation 11 and 12 to improve the distribution of radiation. The sources of ultraviolet radiation 11 and 12 may be of any known type usually used to generate ultraviolet radiation for disinfecting hairdressing tools. The lower compartment 10 is limited by a lower peripheral wall 13, a base 14, and the lower wall 6 of the receiving compartment 4. In this embodiment with ultraviolet radiation source, it is advantageous to provide reflective interior surfaces allowing concentrating the ultraviolet radiation in the useful zone of the receiving compartment 4. For this, in the case where the walls are not made of a material which is itself reflective, for example when they are made of a plastic material such as polymethyl methacrylate (PMMA), in particular the product sold under the trademark PLEXIGLAS, the peripheral wall 5 and the cover 7 of the receiving compartment 4 are provided with a respective inner surface 5a and 7a reflecting. Similarly, the base 14 and the lower peripheral wall 13 of the lower compartment 10 have respective reflective inner surfaces 14a and 13a. By against the lower wall 6 of the receiving compartment 4 must be transparent to ultraviolet radiation, and therefore devoid of reflective surface. For example, we can achieve the lower wall 6 polymethyl methacrylate (PMMA), including the product marketed under the trademark PLEXIGLAS. Such a material has good transparency properties for ultraviolet radiation. 37FDEP.docx 8 The outer walls of the storage case 1, that is the cover 7, the peripheral wall 5, the base 14 and the lower peripheral wall 13 may be opaque, or covered with an opaque outer layer solid color or can receive a decoration or marking.

The ultraviolet radiation source 11 or 12 directs ultraviolet radiation 1 or 12a to the lower wall 6 of the receiving compartment 4, and the lower wall 6 which is transparent to ultraviolet radiation allows said ultraviolet radiation 11a or 12a to penetrate into the compartment. 4 in order to act on the rollers 2 or other tools arranged in the receiving compartment 4. In FIG. 3, the possible structure of the stabilizing means 9, in the form of a cylindrical light passing through the bottom wall 6, and in which can engage the axial lug 2f of the roller 2 to retain the latter in a vertical position. The vertical position of the rollers 2 is advantageous in that it makes it possible to maximize the number of rollers 2 that can be arranged in the receiving compartment 4, while facilitating the gripping of each roll 2 by a handle 3 without disturbing the positioning of the other neighboring rollers. The handle 3 can easily be manipulated and moved according to movements as illustrated by the double arrow 15 for its introduction or removal in the receiving compartment 4 when the lid 7 is open. It is possible to provide stabilization means 9 distributed over the entire surface of the lower wall 6 of the receiving compartment 4. The particular hollow structure of the stabilizing means 9 allows the use of a surface portion of the lower wall 6 either to receive rollers 2, or to receive other hairdressing tools such as scissors, combs, razors, these tools can thus be subjected to ultraviolet radiation for disinfection. Alternatively, it can be provided that the lower wall 6 of the receiving compartment 4 comprises a surface area devoid of stabilizing means 9, this area then being dedicated and available to receive other hairdressing tools. In this case, it may further be provided that the surface area devoid of stabilizing means 9 advantageously comprises holding means specific to the other hairdressing tools, both for maximizing the number of tools that can be received on said surface, and to maximize the effectiveness of ultraviolet radiation on these tools.

37FDEP.docx 9 When using the device illustrated in Figures 1 and 2, the hairdresser can perform a blow-drying process by the following succession of steps: he takes the handle 3, he opens the cover 7 of the housing of 1, it vertically engages the axial lug 3a of the handle 3 in the first gripping end 2c or the upper end of a first roller 2, it fixes the first roller 2 to the handle 3 by the engagement of the lugs retractable 3b in the locking lights 2g, it removes the assembly formed by the first roller 2 and the handle 3. It can then proceed to the winding of a first lock of hair around the first roller 2, and submit said first wick to a stream of hot air produced by a hair dryer. The hairdresser thus holds with one hand the hair dryer, and with the other hand the grip handle 3 and the first roller 2. During the treatment of the first lock of hair, the hairdresser may find it advantageous to work with the roller assembly 2 - handle 3 which forms a brush on which is wound the first lock of wet hair. When heated by a hair dryer, the brush thus formed makes it possible to roll and unroll the first lock of hair, accelerating drying. The brush also helps to smooth the hair by a certain slip. After a first drying of the first strand of hair, the hairdresser can remove the handle 3 away from the first roller 2, which remains in place on the first lock of hair until it is completely dried and cooled. Due to the absence of the handle, the first roller 2 remains balanced and allows a long drying that cools the lock of hair without deforming it. The end of drying is advantageously away from the hair dryer, which improves the brightness of the hair. During the end of drying and cooling of the first strand of hair, the hairdresser can thus, without waiting, repeat the same operation to take a second roller 2 present in the storage box 1, to come place this second roller 2 in the hair and wind a second lock of hair on the second roller 2. After cooling and drying a complete lock of hair, the hairdresser can adapt again the handle 3 on the roller 2 on which is wound said lock of hair, it removes the handle assembly 3 - roller 2 away from said lock of hair, it introduces the roller 2 held by the handle 3 in the receiving compartment 4 by engaging vertically by its axial pin 2f in one of the stabilization means 9, and removes the handle 3 from the receiving compartment 4. When using the device according to the second embodiment 3, the hairdresser performs the same operations as those described in relation to FIGS. 1 and 2 above, and he also performs the disinfection of rollers 2 and hairdressing tools. For this, after arrangement of the rollers 2 and other tools in the receiving compartment 4, it closes the lid 7, it feeds the ultraviolet radiation source 11,12 to subject the rollers 2 and tools to ultraviolet radiation 11a, 12a. It should be noted that the ultraviolet radiation source can be continuously supplied, even during the periods of opening of the lid 7, considering that the radiation is directed essentially upwards and that it is not very harmful in itself. The present invention is not limited to the embodiments which have been explicitly described, but it includes the various variants and generalizations thereof within the scope of the claims below.
