Description

BRUSH TYPE MULTIFUNCTION HAIRDRESSING APPARATUS

ROTARY

The present invention relates to a multifunction hairdressing device of rotating brush type which aims to allow the realization of several types of styling using the same device. In a preferred embodiment, the hairdressing apparatus according to the invention will make it possible to combine the effects of a curling iron, a straightener, a brush and a hair dryer so as to achieve at least three different hairstyles, on dry or wet hair.

In the field of multi-function hairdressing appliances of rotary brush type, it is known the documents JPS54136961A, JPS54136959A, EP1558106 and CN102783802.

In the document JPS54136961A, the hairdressing apparatus comprises a heating mandrel equipped with disks successively arranged one after the other along a shaft. The discs are compressed on each other by means of a tip provided with a spring arranged at the end of the shaft, the spring exerting pressure on these discs. The disks deviate from each other under the constraint of the hair during their positioning consisting of placing them between the lateral faces of these disks and in contact with the shaft. The lateral faces of the discs exert pressure on the hair once positioned as mentioned above. A pull on the tip exerted in the direction of the shaft releases the spring and thus stop the pressure exerted by the discs on the hair, so as to easily disengage the mandrel at the end of styling. This implementation has the disadvantage of not ensuring a proper positioning of the hair between the discs and in contact with the shaft, because of the need to constrain the hair to penetrate between the discs away. In addition, this hairdressing apparatus is not ergonomic because it requires manipulation with the two hands in order to hold the body of the hairdresser with the first hand and pull the tip with the second hand, to remove the hair from the mandrel after styling. The user can not manipulate his hair when they release the mandrel, even during their positioning, as soon as he has to hold the body of the device with one hand and with the other hand the endpiece.

In the document JPS54136959A, the hairdressing apparatus comprises a heating mandrel equipped with a shaft which receives a helical spring whose turns are provided with bristles. A tip arranged at the end of the shaft is configured to be positioned and locked either in a first position in which the spring is compressed, to press the turns against each other after positioning the hair between said turns, either in a second position in which the spring is relaxed, to separate the turns and allow the removal of the hair after styling. This implementation has the disadvantage of not adapting the pressure on the hair according to the variation in the amount of hair between the turns, because the tip is disposed, in a binary manner, in the first position or second position. Indeed, the amount of hair disposed between all the turns will change the pressure exerted by the tip on these turns, this pressure is reflected on the hair. In addition, this hairdressing device is not ergonomic because it requires manipulation with both hands to hold it with the first hand and push or pull the tip with the second hand, to arrange it in the first or second position. When pushing on the mouthpiece with one hand while manipulating the apparatus with the other hand, hair may partially disengage from the turns of the spring and not be properly pressed by said turns.

In documents EP1558106 and CN102783802, the hairdressing apparatus comprises a heating mandrel provided with a shaft on which are arranged a spiral fixed profile and a spiral moving profile. The mobile profile can be either pressurized against the fixed profile or removed from said fixed profile, under the action of a control button. The hair is arranged between the mobile profile and the fixed profile, in contact with the shaft, an action on the control button allows then to press the hair between the turns of the two fixed and mobile profiles, the release of the button allowing the contrary to release the hair after styling. This implementation has the disadvantage of exerting different pressures on each lock of hair caught between each pair of turns of the movable profile and the fixed profile, because of the differences in thickness of the locks compressed between the mobile turns and the fixed turns . Indeed, each turn of the movable profile has a stop position which depends on the thickness of the lock of hair between said moving coil and the fixed turn. These pressure differences can affect the homogeneity of styling. The present invention overcomes the aforementioned drawbacks. To this end, the invention relates to a hairdressing apparatus which comprises a body configured to manipulate said apparatus and a hair styling mandrel which extends the body along a longitudinal axis X and which makes it possible to work the hair for styling purposes. The hairdressing apparatus also comprises means for heating the mandrel which makes it possible to dry the damp hair during their treatment with the mandrel, or even to obtain a better treatment of the hair during handling with the mandrel. In addition, the mandrel includes on its outer side a proximal ring, a distal ring and at least one intermediate ring positioned between said proximal and distal rings. These rings are configured to be positioned joined together, by sliding in one direction, so as to form a roller or to be spaced apart, by sliding in the other direction, so as to allow the insertion of hair into the spacings. formed between said rings. Furthermore, the hairdressing apparatus comprises a device for actuating the rings configured at least to spread the rings so as to insert the hair into said gaps, and to tighten said rings independently of one another according to thicknesses of hair disposed between said rings, while exerting a constant pressure on the hair. Thus, the spacing of the rings to release the hair or position on the mandrel, is easily done. The independent tightening of the rings while ensuring a constant pressure makes it possible to work identically the hair arranged in the spacings between the rings, whatever the variations in thickness that may exist between the locks of hair positioned in said spacings. These features of the hairdressing apparatus according to the invention allow its use for smoothing the hair, positioning them in the spacings between the tightened rings and then exerting traction on these hair. While the roll form of the mandrel, when the rings are contiguous, allows the realization of curls on dry or wet hair. Other hair shaping can be envisaged by means of said hair styling apparatus.

According to one embodiment of the hairdressing apparatus that is the subject of the invention, the rings are configured to be mounted successively sliding relative to one another along the longitudinal axis X. In addition, the actuating device comprises a transmission system configured to telescopically slide the rings during their spacing and during their tightening, by acting on the distal ring and then successively on the intermediate rings and on the proximal ring, during spacing and when tightening the rings .

According to an embodiment of the above-mentioned transmission system, the latter comprises a transmission piece mounted in sliding connection along the longitudinal axis X with respect to the mandrel, means for securing the distal end of the transmission piece. with the distal ring, stop means configured on each ring to come into contact with the preceding ring after a certain stroke in one direction and the other along the longitudinal axis X, and return means of the transmission piece for bringing the rings in contiguous position.

Preferably, according to this embodiment of the transmission system, each ring comprises, in a longitudinal section plane, a slot shape configured to successively slide the rings into each other and to abut on the previous ring after a certain stroke when tightening the rings.

Preferably, according to this embodiment of the transmission system, the abutment means comprise, for the distal ring and the at least one ring intermediate, a rod secured to said ring and abutting against the previous ring after a certain stroke, during the spacing of said rings.

Preferably, according to this embodiment of the transmission system, the securing means comprise a distal shaft secured, on the one hand, to the distal end of the transmission part and, on the other hand, to the distal ring.

According to an embodiment of the actuating device, the latter comprises an actuating trigger arranged on the body and connecting means arranged between the trigger and the transmission system. In the aforementioned embodiment of the transmission system, the trigger allows the activation of the transmission part in translation along the longitudinal axis X, through said connecting means.

According to the hairdressing apparatus object of the invention, the mandrel comprises a drum which has a proximal portion and a distal portion. The distal portion is slidably mounted relative to the proximal portion along the longitudinal axis X, preferably by engagement of the distal portion within the proximal portion. In addition, the rings are slidably mounted on the drum, preferably on the proximal portion. On the contrary, a variant could be envisaged according to which the proximal portion engages in the distal portion to effect this sliding, the rings being slidably mounted on the distal portion of the drum.

According to this aforementioned preferred embodiment of the mandrel, the distal ring is attached to the distal portion of the drum and is mounted in sliding connection vis-à-vis the proximal portion of the drum. In addition, the at least one intermediate ring and the proximal ring are mounted in sliding connection with respect to the proximal portion.

According to this embodiment of the mandrel, the drum is mounted pivotally connected along the longitudinal axis X vis-à-vis the body. In addition, the hairdressing apparatus comprises means for driving the drum in rotation. Thus, the hairdressing apparatus has a rotating mandrel which facilitates the handling of said device during the treatment of the hair, in particular for making a looping. However, a simplified embodiment of the hairdressing appliance according to the invention could be envisaged with a non-rotating mandrel with respect to the body. According to this implementation of the hairdressing apparatus, with the rotary mandrel, the transmission system is arranged inside the drum, connecting means being configured to translate said transmission system along the longitudinal axis X, to inside the proximal portion of said drum.

According to this embodiment of the mandrel, the heating means of the hairdressing apparatus comprise at least one heating element arranged inside the drum. In addition, the drum is made of a material that provides thermal conduction to transfer heat from the heating element to the hair being treated. Preferably, this at least one heating element is arranged on the inner wall of the drum, which makes it possible to heat the outer face of the mandrel more accurately while providing a wider temperature range than when the heating element is simply disposed within the drum without direct contact therewith, this solution still possible in a less effective embodiment variant. According to one embodiment of the hairdressing apparatus object of the invention, the heating means comprise a hot air blowing system configured to project hot air along the outer wall of the mandrel. Preferably, the mandrel comprises a base and a head, the hot air blowing system being configured to project hot air at least through outlets arranged at the base and the head. This optimizes the distribution of hot air blown on the hair on both sides of the mandrel. Other alternative embodiments are conceivable, for example the implementation of a hot air blowing system configured to project hot air radially to the mandrel, through the rings. According to the hairdressing apparatus object of the invention, it comprises a blocking system configured to act on the actuating device and concomitantly move the rings in contiguous position, in a position spaced from a base of the mandrel or conversely, in a tightened position vis-à-vis said base, upon activation of said actuator. This implementation makes it possible to loop the hair by means of the hair-styling device, by previously blocking the end of a lock of hair between the proximal ring and the base, after having simultaneously discarded the rings and then tightened concomitantly with those and then winding the wick around the mandrel, either manually when the mandrel is non-rotating or, preferably, automatically when the chuck is rotatable and motorized. This locking system facilitates the gripping of the end of the lock of hair by means of the rings and then its winding around the mandrel to achieve the looping. According to this embodiment of the hairdressing appliance, it comprises a control button of the locking system for activating and deactivating said locking system. The looping of the hair can also be performed on dry or wet hair thanks to the heating means of the mandrel.

According to the hairdressing apparatus object of the invention, it comprises a sleeve configured to be attached to the mandrel. This sleeve includes bristles. Thus, the sleeve can be arranged or removed from the mandrel at will, in order to achieve a tensioning and shaping of the hair by means of the hairdressing apparatus, optionally in addition to a heat treatment on wet hair. In a preferred embodiment of the hairdressing apparatus object of the invention, it comprises between four and eight intermediate rings, preferably five intermediate rings.

The following description highlights the characteristics and advantages of the hairdressing appliance according to the invention in a non-limiting embodiment based on figures, among which: Figures 1 and 2 illustrate, in a first longitudinal sectional plane, a hairdressing apparatus object of the invention with rings respectively in the spaced apart position and in the constricted position;

As illustrated in Figures 1 to 4, the hairstyling device 1 comprises a body 2 and a mandrel 3. The mandrel 3 is arranged in the longitudinal extension of the body 2, along a longitudinal axis X. This mandrel 3 comprises a drum 4 which has a proximal portion 5 and a distal portion 6, as illustrated in more detail in Figures 3, 4 and 6. The distal portion 6 is slidably mounted along the longitudinal axis X within the proximal portion 5. The mandrel 3 comprises a proximal ring 7, five intermediate rings 8-12 and a distal ring 13, as illustrated in Figures 1 to 3. The proximal rings 7, 8-12 intermediate and distal 13 are also illustrated in the figures 5 to 7. The number of intermediate rings is variable depending on the length of mandrel 3 or even the number of pressures on the hair that it is desired to perform in a single hair treatment operation. We will preferably choose between four and eight intermediate rings. With regard to these FIGS. 1 to 7 show that the proximal ring 7, the intermediate rings 8-12 and the distal ring 13 have a crenellated shape in a longitudinal sectional plane passing through the longitudinal axis X.

As shown in more detail in FIGS. 5 and 6, the proximal ring 7 comprises an inner cylinder 7a and an outer cylinder 7b interconnected by a shoulder 7c, and also comprises a circular base 7d which partially closes the distal end of the outer cylinder 7b. Similarly, the intermediate rings 8-12 each comprise an inner cylinder 8a-12a and an outer cylinder 8b-12b interconnected by a shoulder 8c-12c, and a circular base 8d-12d which partially closes the distal end. of the outer cylinder 8b-12b. The distal ring 13 also includes an inner cylinder 13a and an outer cylinder 13b interconnected by a shoulder 13c, but lacks a circular base. The distal end 14 of the outer cylinder 13b of the distal ring 13 is nested on a shouldered head 15 of the distal portion 6 of the drum 4, as illustrated in particular in Figures 5 and 6. The circular base 7d of the proximal ring 7 is slidably mounted along the longitudinal axis X on the inner cylinder 8a of the first intermediate ring 8. Similarly, the circular bases 8d-1 1 d intermediate rings 8-1 1 are successively slidably mounted along the longitudinal axis X on the inner cylinders 9a-12a of the following intermediate rings 9-12. The circular base 12d of the last intermediate ring 12 is slidably mounted along the longitudinal axis X on the inner cylinder 13a of the distal ring 13.

The hairdressing appliance 1 comprises a connecting piece 16 illustrated in FIGS. 1 to 6. This connecting piece 16 is arranged along the longitudinal axis X and comprises a handwheel 17 fastened to a hollow shaft 18. The distal end of the The flywheel includes a shoulder 17a illustrated in greater detail in FIGS. 5 and 6. As illustrated in greater detail in FIGS. 1 to 6, the proximal portion 5 of the drum 4 comprises a base 19 whose proximal end also comprises a shoulder 19a. . This base 19 is assembled with the flywheel 17 by means of fixing screws housed in places 20 provided for their screwing, as illustrated in FIGS. 1 to 6, said assembly making it possible to constitute a 21 by the disposition vis-à-vis said shoulders 17a, 19a respectively on the wheel 17 and the base 19, as illustrated in particular in Figures 5 and 6.

As illustrated in Figures 1 to 6, the body 2 comprises at its distal end 2a an internal cylindrical portion 22 in which are housed the flywheel 17 of the connecting piece 16 and in part the base 19 of the proximal portion 5 of the drum 4. This internal cylindrical portion 22 comprises protuberances 23 each provided with a lug 23a, preferably six, uniformly distributed around said internal cylindrical portion 22. These lugs 23a are housed in the groove 21 arranged between said flywheel 17 and said base 19, as illustrated in more detail in FIGS. 5 and 6, and provide a pivotally mounted connection along the longitudinal axis X of the connecting piece 16 and the proximal portion 5, with respect to the body 2 The hollow shaft 18 of the connecting piece 16 extends in the body 2 along the longitudinal axis X and is secured at its proximal end 18a to the distal end 24b of a transmission shaft. 24, also hollow, such as FIGS. 1 to 4 and 6. The proximal end 24a of this transmission shaft 24 is connected to a rotary drive motor 25. Two rings 26a, 26b are complementarily mounted between the transmission shaft 24 and the inner wall 27 of the body 2, so as to ensure the pivot connection along the longitudinal axis X of the proximal portion 5 of the drum 4, connecting piece 16, transmission shaft 24, vis-à-vis the body 2.

As illustrated in FIGS. 1, 2, 5 to 8, the proximal portion 5 of the drum 4 is hollow and comprises two housings 28, 29 arranged longitudinally in facing relation to the cylindrical inner wall of said proximal portion 5. These housings 28, 29 are configured to receive heating elements 31, 32, preferably positive temperature coefficient CTP sensors. These heating elements 31, 32 are electrically connected by means of cables 33, 34 which pass through the hollow shaft 18 of the connecting piece 16 and the transmission shaft 24, the ends 33a, 34a of these cables 33 , 34 being connected by means of a rotating electrical connector 35 to an electronic management card (not shown in the figures), as shown in the figures 1 and 2. Thus, the heating elements 31, 32 are in direct contact with the drum 4, itself in contact with the rings 7-13. This makes it possible to set the heating temperature of the rings 7-13 more precisely and offers a greater range of control of the heating temperature since the heat transfer by heat conduction through the drum 4 is improved. by this direct contact with the heating elements 31, 32. It will be chosen for this a material providing good thermal conduction for the implementation of the drum 4, for example aluminum.

As illustrated in FIGS. 1 to 4, a fan 36 is arranged inside the body 2, at its proximal end 2b. A perforated cover 37 closes this proximal end 2b and ensures an air intake when the fan 36 is started, which then blows the air into the chamber 38 of the body 2. A second heating element 39, for example sensors With positive temperature coefficient, is arranged in the central part of the chamber 38. The air blown by the fan 36 passes through this second heating element 39, which allows to heat it, then this heated air is propagated in said chamber 38 to the distal end 2a of the body 2.

As illustrated in FIGS. 1 to 6, the protuberances 23 on the internal cylindrical portion 22 of the body 2 make it possible to maintain a spacing with the flywheel 17 of the connecting piece 16 and the base 19 of the proximal portion 5 of the drum 4 , which makes it possible to constitute a duct which communicates with the chamber 38 and which opens out at the air outlets 40 at the distal end 2a of the body 2. These air outlets 40 make it possible to blow the hot air through the longitudinal direction, from the base 3a of the mandrel 3, at the surface of the outer cylinders 7b-13b of the rings 7-13 constituting the outer wall of said mandrel 3.

As illustrated in FIGS. 1 to 6, the proximal and distal portions 6 of the drum 4 are hollow and define a chamber 41. The flywheel 17 of the connecting piece 16 comprises four openings 42 which communicate with the chamber 41 of the drum 4. Thus, the hot air is propelled by the fan 36 in the chamber 41, to the shouldered head 15 of the distal portion 6 of the drum 4. A closure cap 43 comprises studs 44 which allow its attachment with the shoulder head 15, by means of screws (not shown). These studs 44 make it possible to maintain a spacing 45 between the inner wall 43a of the closure cap 43 and the shoulder head 15, which forms a channel communicating with said chamber 41. In addition, the inner wall 43a has a curved shape as illustrated in Figures 1 to 3, allowing said spacing 45 to form a deflector with an air outlet 46 at the head 3b of the mandrel 3, facing the rings 7-13. This air outlet 46 is used to blow the hot air to the rings 7-13 in the direction of the longitudinal axis X, at the surface of the outer cylinders 7b-13b.

The hairdressing apparatus 1 comprises a transmission part 47 illustrated in FIGS. 1 to 8. This transmission part 47 comprises two arms 48, 49 which extend longitudinally in the chamber 41 of the drum 4. These arms 48, 49 are slidably mounted along the longitudinal axis X, through two opening openings 50, 51 arranged on the flywheel 17 of the connecting piece 16. Thus, thanks to this slide connection, the rotational drive of the connecting piece 16 , through the motor 25, allows to drive simultaneously the transmission piece 47 in rotation along the longitudinal axis X. The transmission part 47 comprises a spider 52 which is secured to the distal ends 48b, 49b of the arms 48, 49 , as illustrated in particular in FIGS. 1 and 2. Similarly, the transmission part 47 comprises a guide ring 53 which is secured to the proximal ends 48a, 49a of the arms and which is slidably mounted relative to the hollow shaft 18 of the connecting piece 16, along the longitudinal axis X. The spider 52 and the guide ring 53 are rotated along the longitudinal axis X with the two arms 48, 49 to which they are subject, during the starting the engine 25.

As illustrated in Figures 1 to 4, the hairstyling device 1 comprises a trigger 54 which is mounted in pivot connection 55 on the outer side of the body 2 and allows the actuation of two connecting rods 56, 57 to which it is subject . The distal ends 56b, 57b of these rods 56, 57 each comprise a light 58, 58 'of oblong shape. A sliding ring 59 is in sliding contact with the guide ring 53, as illustrated in these figures 1 to 4 and 6. The sliding ring 59 comprises two nipples 60, 61 which extend in opposition, as illustrated in particular in Figures 3, 4 and 6, and are housed respectively in the lights 58, 58 'on the rods 56, 57. The sliding ring 59 is also slidably mounted along the longitudinal axis X, vis-à-vis -vis the hollow shaft 18 of the connecting piece 16. An actuation of the trigger 54, a first position shown in Figure 2 to a second position shown in Figure 1, is used to translate the slip ring 59 to the front of the hollow shaft 18, which concomitantly causes the translation towards the front of the guide ring 53 and, therefore, of the transmission part 47. When the motor 25 is activated, the ring guide 53 is rotated, as explained above, and therefore rubs on the sliding ring 59 which is secured to the connecting rods 56, 57. As illustrated in FIGS. 1 to 6, the hairdressing apparatus 1 comprises a proximal shaft 62, five intermediate rods 63-67 and a distal shaft 68. The proximal shaft 62 is arranged radially and passes through two oblong-shaped slots 69, 70 arranged longitudinally on the inner cylinder 7a of the proximal ring 7, the ends 62a, 62b of the proximal rod 62 being housed in two holes 103a, 103b arranged radially on the proximal portion 5 of the drum 4. Thus, the proximal ring 7 is mounted in sliding connection with respect to the proximal portion 5, along the longitudinal axis X, with a displacement stroke limited to the length of the lumens 69 , 70.

As illustrated in particular in Figures 1, 2, 5 and 6, the proximal portion 5 of the drum 4 comprises two longitudinal slots 71, 72 which extend parallel to the longitudinal axis X and which are arranged vis-à- This distal portion 6 of the drum 4 comprises two grooves 73, 74 which open out at the proximal end 6a of said distal portion 6 and which are arranged facing each other in the distal portion 6, respectively. alignment of the longitudinal slots 71, 72, as illustrated in particular in Figures 5 and 6. As illustrated in particular in Figures 1 to 6, the intermediate rods 63-67 are arranged radially and each pass through the two longitudinal slots 71, 72. The two ends 63a-67a of these intermediate rods 63-67 respectively pass to through two holes opening 75a-79a, illustrated in FIG. 6, arranged radially and vis-à-vis the internal cylinders 8a-12a of the intermediate rings 8-12, which are slidably mounted along the longitudinal axis X with respect to the proximal portion 5 of the drum 4. This design makes it possible to mount the intermediate rings 8-12 in a sliding connection with respect to the proximal portion 5 of the drum, along the longitudinal axis X. these two ends 63a-67a, 63b-67b intermediate rods 63-67 are housed inside the preceding rings 7-1 1 forming crenellations, in the portions corresponding to the outer cylinders 7b-1 1b of said rings previous 7 -1 1, te As illustrated in FIG. 6, the internal cylinders 8a-12a of the intermediate rings 8-12 are slidably mounted along the longitudinal axis X with respect to the circular bases 7d-1 1 d of the preceding rings. -1 1, as already explained above. Thus, each intermediate ring 8-12 can slide along the longitudinal axis X vis-à-vis the ring 7-1 1 which precedes, or downstream until the ends 63a-67a, 63b- 67b of the intermediate rod 63-67 abut against the inner side of the circular base 7d-1 1 d of the ring 7-1 1 previous, as shown in Figure 3, or upstream until that the shoulder 8c-12c on the intermediate ring 8-12 comes into abutment against the outer face of the circular base 7d-1 1 d of the previous ring 7-1 1, as appears in particular in Figures 5 and 6. In addition, the rotation of the intermediate ring 8-12 vis-à-vis the ring 7-1 1 which precedes it is blocked through the longitudinal slots 71 -72 through which pass the intermediate rods 63-67, which which assures a mounting in slide connection with a limited stroke of each intermediate ring 8-12 vis-à-vis the ring 7-1 1 which preceded e.

In a manner comparable to the above-mentioned features, as illustrated in particular in FIG. 6, the distal rod 68 is arranged radially and passes through the two longitudinal slots 71, 72 of the proximal portion 5 of the drum 4. The two ends 68a of the distal stem 68 pass respectively in two opening holes 80a arranged radially facing the inner cylinder 13a of the distal ring 13, which is slidably mounted along the longitudinal axis X with respect to the proximal portion 5 of the drum 4. design allows a slide connection of the distal ring 13 vis-à-vis the proximal portion 5 of the drum, along the longitudinal axis X. In addition, these two ends 68a, 68b of the distal rod 68 are housed inside the intermediate ring 12 which precedes it, in the portion corresponding to the outer cylinder 12b of said intermediate ring 12. As explained above, the inner cylinder 13a of the distal ring 13 is slidably mounted along the longitudinal axis X vis-à-vis the circular base 12d of the intermediate ring 12 previous. Thus, the distal ring 13 can slide along the longitudinal axis X vis-à-vis the intermediate ring 12 which precedes, or downstream until the ends 68a, 68b of the distal rod 68 come into abutment against the inner side of the circular base 12d of said intermediate ring 12, or upstream until the shoulder 13c on the distal ring 13 abuts against the outer face of the circular base 12d of the ring intermediate 12. Furthermore, the rotation of the distal ring 13 vis-à-vis the intermediate ring 12 is blocked through the longitudinal lumens 71 -72 through which passes the distal rod 68, which ensures a connection assembly slide with a limited stroke of the distal ring 13 vis-à-vis the intermediate ring 12 which precedes. The distal rod 68 is further secured to the spider 52 through which it passes, as illustrated in particular in Figures 3 and 5. The ends 68a, 68b of the distal rod 68 pass respectively through the two grooves 73,74 of the portion distal 6 of the drum, as shown in Figure 6, which blocks the rotation of the distal portion 6 vis-à-vis the distal ring 13 along the longitudinal axis X.

When activating the trigger 54 of the first position illustrated in FIG. 2 towards the second position illustrated in FIG. 1, the transmission part 47 undergoes a forward translation along the longitudinal axis X, which, in fact, the securing between the spider 52, the distal rod 68 and the distal ring 13, ensures the forward displacement of said distal ring 13 and the distal portion 6 of the drum 4, the latter translating along the longitudinal axis X Visa- 5). At the same time, the distal ring 13 translates against the intermediate ring 12 which precedes it until the ends 68a, 68b of the distal rod 68 abut against the circular base 12d of said intermediate ring 12, which then causes forward translation along the longitudinal axis X of the intermediate ring 12, vis-à-vis the intermediate ring 1 1 which precedes. When the ends 67a, 67b of the intermediate rod 67 abut against the circular base 1 1 d of the intermediate ring 1 1 previous, it in turn translates vis-à-vis the intermediate ring 10 which precedes. The action is repeated as follows until the last intermediate ring 8 drives in translation the proximal ring 7, once the ends 63a, 63b of the last intermediate rod 63 abut against the circular base 7d of said proximal ring 7. The proximal ring 7 translates along the longitudinal axis X vis-à-vis the proximal portion 5 of the drum and the proximal rod 62 until the lights 69,70 on the proximal ring 7 come into abutment on the ends 62a, 62b of the proximal rod 62, which stops the deployment of the mandrel 3. In this extended position of the mandrel 3, the proximal ring 7 has a spacing 81 vis-à-vis the base 19 of the portion proximal 5 of the drum 4 and the rings 7-13 have spacings 82-87 between them. The actuating device as described above thus makes it possible to deploy successively, in a telescopic manner, the rings 7-13 until they reveal between them the spacings 81 -87 which allow the insertion of locks of hair.

The hairstyling device 1 is configured so that the trigger 54 automatically returns to the position illustrated in FIG. 2 when the user releases this trigger 54, after having positioned the hair in the spacings 81 - 87. For this, means of recall provide an automatic translation of the transmission part 47, once the trigger 54 released. Preferably, these return means consist of two springs (not shown in the figures) which are respectively arranged on the two arms 48, 49. These two springs can be arranged in the part of the arms 48, 49 located between the wheel 17 the connecting piece 16 and the spider 52; in this case the springs work in extension. One could instead provide an arrangement of these two springs in the portion of the arms 48, 49 located between the wheel 17 and the ring or the guide ring 53, said springs working in this case in compression. The stiffness constant of the springs will be dimensioned to ensure this automatic return of the trigger 54. However, a lower stiffness constant could be provided by previously actuating the trigger 54 manually to bring it back to the position illustrated in FIG. 2, the springs then pushing concomitantly the transmission piece 47 rearwardly by keeping it pressed against the ring or the sliding ring 59. When the transmission piece 47 translates towards the rear of the hairstyling apparatus 1, along the longitudinal axis X , this latter concomitantly causes the translation of the distal ring 13 and the distal portion 6 of the drum 4 which slide relative to the proximal portion 5 of the drum 4. The hair disposed in the distal distance 87 located between the shoulder 13c of the distal ring 13 and the circular base 12d of the intermediate ring 12, are then compressed until a compression limit is reached. This compression limit then causes the concomitant displacement of the distal ring 13 and the intermediate ring 12 above. The hair disposed in the last intermediate distance 86 is in turn compressed until a compression limit is reached causing the concomitant movement of the distal ring 13 and the two last intermediate rings 12-1 1. The action is repeated as follows until the proximal ring 7 translates concomitantly with the distal ring 13 and all the intermediate rings 8-12. Once the hair disposed in the proximal spacing 81 located between the shoulder 7c of the proximal ring 7 and the base 19 of the proximal portion 5 of the drum 4, are compressed, the return springs of the transmission part 47 balance the pressure exerted on the hair arranged in the spacings 81 -87 between the rings 7 -13, regardless of the thicknesses of hair located in these spacings 81 -87, given the narrowing or the telescopic return of the rings 7-13 of the mandrel 3, starting from the distal ring 13 to the proximal ring 7. The hairstyling apparatus 1 comprises a locking piece 88 appearing in FIGS. 1 to 8. This locking piece 88 comprises an end axis 89 which is divided into two branches 90, 91 which extend parallel to the axis longitudinal X, at the ends of which are respectively arranged two fingers 92, 93. A reinforcing bar 94 stiffens the two branches 90, 91. The end axis 89 is subject to a control button 95 which is mounted pivotally connected along the longitudinal axis X, vis-à-vis the closure cap 43. The control button 95 allows to actuate the rotation of the locking piece 88 along the longitudinal axis X, of an unlocked position in which the fingers 92, 93 are disengaged with respect to the first intermediate rod 63, as illustrated in FIGS. 5 and 7, towards a position locked said fingers 92, 93 are engaged between the proximal shaft 62 and the first intermediate rod 63, and abut against said first intermediate rod 63. In this locked position, the actuation of the trigger 54 - similarly to the actuation making it possible to go from a position of the trigger illustrated in FIG. 2 to that illustrated in FIG. 1 - makes it possible to translate the transmission piece 47 forwardly, which moves the distal ring 13 simultaneously, the distal portion 6 of the drum with the closure cap 43 and, therefore, the locking piece 88. The fingers 92, 93 then drive the first intermediate rod 63, which simultaneously moves the intermediate rings 8-12 and the ring distal 13 which remain contiguous. When the ends 63a, 63b of the first intermediate rod 63 come into contact with the inner face of the circular base 7d of the proximal ring 7, the latter is then also driven in translation along the longitudinal axis X, with the other rings 8 -13 contiguous, until the lights 69, 70 on the inner cylinder 7a abut against the proximal shaft 62. Only appear then the proximal spacing 81 and the first intermediate spacing 82, in which can be placed hair . The release of the trigger 54 allows the concomitant translation backwards, under the action of the springs, the distal ring 13 and the intermediate rings 8-12, which first tightens the first intermediate spacing 82 until that the proximal ring 7 also translates, the proximal gap 81 then tightening in turn. The rings 8-13 in contiguous position form a roller around which can be wound the hair which is held at their ends, at the tips, for the realization of a looping. An alternative embodiment could be envisaged according to which all the rings 7-13 would move together and concomitantly to reveal only the proximal spacing 81 when the trigger 54 is activated. In this case, it would be advisable to add an element abutment (not illustrated) complementary subject to the proximal ring 7, which would come into contact with the fingers 92, 93 of the locking piece 88.

As illustrated in Figure 9, the hairdressing apparatus includes a sleeve 96 which is configured to be positioned around the mandrel 3 when the rings 7-13 are disposed contiguously. The sleeve 96 comprises bristles (not shown in Figure 9 for a better reading thereof) which are distributed radially and uniformly on the sleeve at holes 97 which allow the assembly of these bristles on the sleeve 96. sleeve 96 comprises two semi-cylindrical portions 98, 99 which are mounted in pivot connection 100 relative to one another along a longitudinal axis X1 parallel to the longitudinal axis X at their first edges 98a, 99a; which makes it possible to open the sleeve 96 to position it around the mandrel 3 and then to close the sleeve to tighten it around the mandrel 3. The second edges 98b, 99b of the two parts 98, 99 are held together in closed position, by means of two clips 101, 102, illustrated in Figure 9. This sleeve 96 allows to use the hairstyling device 1 for brushing hair.

Thus, the aforementioned characteristics of the hairdressing appliance 1 offer several possible uses. By positioning and pressing the hair in the spacings 81-87 between the rings 7-13 and the base 19 of the proximal portion 5 of the drum 4, near the roots of the hair, and then by translating the hairstyling apparatus 1 of the roots towards the ends of the hair, a smoothing is performed. By positioning and pressing the tips of the hair in the spacing 81 between said base 19 and the proximal ring 7, then by wrapping the hair around the rings 7-13 joined and forming a roll, a loop is made. By adding the sleeve 96 around the mandrel 3, the hair is brushed. These different operations can further be performed on dry or wet hair, using the heating means, that is to say the heating elements 31, 32 which provide thermal conduction through the drum 4 and the rings 7-13 and , in addition or independently, the fan 36 and the second heating element 39 which allow the blowing of hot air through the base 3a and the head 3b of the mandrel 3, along the outer surface of said mandrel 3.

The hairdressing appliance 1 comprises other characteristics such as a control system of the heating means for adjusting the heating temperature of the heating elements 31, 32, 39 and for adjusting the speed of the fan 36.

It is possible to envisage alternative embodiments of the device for actuating rings 7-13 while retaining a tightening of these rings 7-13 independently of one another and a constant pressure between them. For example, the trigger 54 and the connecting rods 56, 57 may be replaced by another system for actuating the transmission part 47. The transmission system, that is to say the transmission part 47, can also be modified. the connecting piece 16, the rods 62-68, the shape of the rings 7-13, the return means (not shown) and the drum 4 consisting of the two proximal portions 5 and 6 distal, while achieving a similar telescopic mounting rings 7-13 which allows to separate the rings 7-13 between them, then to tighten independently said rings 7-13 while maintaining a constant pressure despite variations in hair thicknesses in the spacings 81 -87.

It is also possible to envisage variants of ring locking systems 7-13 replacing the blocking piece 88, so as to spread the rings 7-13 in a contiguous manner with respect to the base 19 of the drum 4.

It is also possible to find alternative means for heating the mandrel 3, replacing the heating elements 31, 32.

The embodiment described above has the advantage of limiting the bulk of the chamber 41 of the drum 4, which contributes advantageously to arrange the heating elements 31, 32 directly in said chamber 41 and in direct contact with the inner wall 30 of the drum 4, which provides the aforementioned advantages. It will therefore be preferred embodiments of the hairdressing apparatus 1 which also allow an arrangement of heating means directly in the mandrel 3 and in contact with its inner wall.
