  • the motorized roller 3 is thus designed to move the lock of hair to be styled C relative to the main body 2, for example at a speed of for example between 1 and 5 cm/s, preferably equal to approximately 2 cm/s.
  • the motorized roller 3 is capable of moving the wick C at an ideal speed (for example in accordance with the aforementioned values) to obtain a satisfactory styling result.
  • the roller motorized 3 thus makes it possible to automate the styling operation, for example with a view to obtaining a straightening effect (in accordance with the illustrated embodiment) by moving the strand of hair to be styled C between straightening plates, like this will be described in more detail in the following.
  • the invention is however not limited to the implementation of straightening and the motorized roller 3 can alternatively be intended to set in motion the strand of hair C with a view to rather giving the latter a curl, a wave or any other desired formatting effect.

  • the pressing roller 17 is also preferably unheated, and is therefore substantially at room temperature, to promote the cooling of the wick mentioned above.
  • the pressing roller 17, like the motorized roller 3, is preferably made of a material promoting local adhesion of the hair, for example a rubber, elastomer or foam type material.
  • the pressing roller 17 is freely rotatable, but it is perfectly possible, according to an alternative variant not illustrated, that the pressing roller 17 is also directly motorized.
  • said motorized roller 3 and pressing roller 17 are respectively integral with the first and second pressure surfaces 7, 8, so that the motorized roller 3 moves advantageously with the first surface pressing roller 7, while the pressing roller 17 advantageously moves with the second pressing surface 8.
  • the pressing roller 17 advantageously reaches its pressing configuration when the clamping device is in clamping configuration, and reaches its configuration released when the clamping device 6 is in the insertion configuration. It is alternatively possible that the motorized roller 3 is secured to the second pressure surface 8 and that the roller 17 is secured to the first pressure surface 7.
  • the motorized roller 3 is advantageously secured to the first pressure surface 7 so as to move with it, while the pressing roller 17 is secured to said second pressure surface. 8 so as to move with it, said close positions then being reached when said first and second pressure surfaces 7, 8 are in clamping configuration, while the spaced position is reached when said first and second pressure surfaces 7, 8 are in introductory configuration.
  • the clamping device 6 comprises a first frame 18 mounted movably relative to the main body 2 between a clamping position corresponding to the clamping configuration and an insertion position corresponding to the insertion configuration, said first frame 18 carrying the first pressure surface 7 as well as the motorized roller 3.
  • the first chassis 18 is thus advantageously designed to move in circular translation relative to the main body 2, in order to move the first pressure surface 7 between its clamping and insertion configurations ( and vice versa) and the motorized roller 3 between its close and separated positions (and vice versa).
  • the clamping device 6 also comprises at least a second frame 19 also mounted movable relative to the main body 2 between a clamping position corresponding to the clamping configuration and an insertion position corresponding to the insertion configuration of the clamping device 6.
  • the second chassis 19 advantageously embeds said second pressure surface 8 as well as a support 20 which embeds itself the pressing roller 17.
  • the first and second frames 18, 19 advantageously form respectively first and second movable jaws relative to the main body 2 intended to grip the lock of hair C to be straightened, while allowing sliding between said jaws of said lock of hair C under the effect of the movement of the latter generated by the motorized roller 3 in cooperation with the pressing roller 17.
  • the pressing roller 17 is mounted to rotate along the second axis YY' relative to the support 20 , the movement of the second frame 19 relative to the main body 2 concomitantly causing the movement of the pressing roller 17 and the second axis of rotation YY' relative to the main body 2.
  • the support 20 is itself advantageously mounted movable relative to the second frame 19 between at least one rest position which it occupies as long as the second chassis 19 is in the insertion position and an engagement position which it occupies when the second chassis 19 reaches its clamping position.
  • the styling device 1 can adapt to the characteristics of the lock of hair C, and in particular to the thickness of the latter, by adjusting, preferably automatically, the size of the interstitial space between the pressing roller 17 and the motorized roller 3, so as to promote local adherent contact, while avoiding a possible jamming of hair C between rollers 3, 17.
  • the support 20 is advantageously mounted to rotate along a third axis of rotation ZZ' secured to the second chassis 19 and which therefore moves with the latter.
  • the engagement position of the support 20 is thus floating, to adapt to the thickness of the lock of hair C.
  • the support 20 is advantageously mounted floating relative to the second frame 19, of so as to be able to move freely relative to the second chassis 19, preferably pivoting along the third axis of rotation ZZ' relative to the second chassis 19 between its rest and engagement positions. This allows to adapt the position of the pressing roller 17 to the thickness of the strand of hair C interposed between said motorized rollers 3 and pressing roller 17.
  • the support 20 and the main body 2 are provided with respective complementary interengagement surfaces 201, 21 which cooperate to transform the movement of the second chassis 19 (preferably in a circular translation movement) relative to the main body 2 in rotational movement of the support 20 relative to the second chassis 19, in order to thus control the passage of the support 20 from its rest position to its engagement position and vice versa.
  • the interengagement surface 21 with which the support 20 is provided forms a cam path against and along which moves one or more cam followers (for example of spherical shape as illustrated) forming the interengagement surface 201 of the support 20.
  • an elastic return means is also provided to permanently return the interengagement surfaces 201, 21 against each other.
  • This return means is for example in the form of a spring which permanently forces the cam follower(s) secured to the support 20 against the cam surface 201 secured to the main body 2.
  • This floating assembly controlled by cam thus makes it possible to automatically bring the pressing roller 17 into a perfectly functional position relative to the motorized roller 3 when passing from the introduction configuration to the clamping configuration of the clamping device 6.
  • the passage of the support 20 from its rest position to its engagement position is obtained by direct engagement of the pressing roller 17 by the motorized roller 3, so that when the device 1 is closed (transition from the introduction configuration to the clamping configuration), the pressing roller 17 rolls against and on the motorized roller 3 to thus be pushed back laterally and reach its close position allowing the training of the bit.
  • the rollers 3, 17 remain permanently parallel to each other, in accordance with the embodiment of the figures 1 to 13 .
  • the torque limiter is therefore advantageously designed to play its role only when the first and second complementary coupling parts 23, 24 are coupled, and in this case it makes it possible to automatically interrupt (without user intervention) the torque limiter. transmission between the motor 4 and the roller 3, if for example a jam of the drive device formed by the rollers 3, 17 occurs.
  • the torque limiter can take any known form, and consist for example of a friction torque limiter or a frictionless torque limiter, with obstacle (for example with teeth, rollers or balls).
  • the first and second complementary coupling parts 23, 24 themselves form, in their coupled configuration, said torque limiter.
  • said first and second complementary coupling parts 23, 24 are advantageously, in coupled configuration, inter-engaged by adhesion (to form a friction torque limiter) or by obstacle (to form a frictionless torque limiter , for example with teeth, balls or rollers), and slip relative to each other as soon as the aforementioned threshold value is reached.
  • the main body 2 also carries means 22 for combing said lock of hair C intended to be set in motion by said motorized roller 3.
  • the combing means 22 is advantageously arranged upstream of the clamping device 6 relative to the direction of movement D of the wick C.
  • the combing means 22 comprises for example a plurality of teeth or bristles arranged in rows or in tufts, so as to form a comb or a brush.
  • the combing means 22 advantageously makes it possible to divide the lock C to be shaped into a plurality of small elementary locks, and to distribute the latter well on the treatment surfaces formed by the pressure surfaces 7, 8.
  • the combing means 22 thus allows the wick C to be well spread between the jaws to promote its shaping by the surfaces 7, 8, which are preferentially heated.
  • the combing means 22 also provides a function of tensioning the lock of hair C , in particular by opposing a local resistance by friction of the lock of hair C to the traction operated by the motorized roller 3 / roller couple. pressing 17 conjugates.
  • the combing means 22 is itself pivotally mounted between a folded position which it occupies when the clamping device 6 is in the insertion configuration, in order to facilitate the installation of the wick C within the clamping device 6, and a raised position that it occupies when the clamping device 6 is in the clamping configuration.
  • the passage from one of said folded down and raised positions to the other is advantageously automatic and obtained for example by means of a cam type drive to transform the movement of the first frame 18 into movement of the combing means 22.
  • the combing means 22 is provided with a cam surface 22A which cooperates with a complementary surface 22B forming a cam follower integral with the first frame 18, the combing means 22 being advantageously permanently recalled, for example by means of a spring, in its raised position, and pushed back into its folded position by cooperation of the surfaces 22A, 22B when the first chassis 18 returns to its insertion position from its engagement position. It is however perfectly possible, in accordance with the alternative embodiment of the figures 14 and 15 , that the combing means is fixedly mounted. Mobile assembly such as that of figures 1 to 13 is however preferred because it allows particularly effective tensioning and combing.
  • the invention ultimately allows, particularly in its preferred mode, figures 1 to 14 , to automatically straighten strands of hair in a particularly reliable, simple and rapid manner, while allowing positioning of the styling device 1 as close as possible to the user's scalp to straighten the strands of hair to a maximum length.
  • the invention thus relates to a styling device 1 which is preferably specifically intended for straightening hair and whose closed position of the styling surfaces pressure 7, 8 corresponds to the natural configuration (rest configuration) of the device 1.
  • this natural rest position which corresponds to the clamping configuration of the clamping device 6, the motorized rollers 3 and pressing rollers 17 are in close position, while the control means 9 is in a deployed elastic return position.
  • the pressing roller 17 is at a distance from the motorized roller 3 (spaced position), while the clamping device 6 is in the insertion configuration.
  • the device 1 spontaneously returns to its natural rest configuration (closed configuration described above).
  • the operation and use of the device 1 are for example as follows.
  • the user first grabs a lock of hair C with one hand and grabs the device 1 with his other hand, preparing to position it against his scalp, or at least close to the latter, so as to that the motorized roller 3 and the pressing roller 17 are arranged close to the scalp while the combing means 22 is arranged opposite said rollers 3, 17, furthest from the scalp.
  • the user can then move the device 1 to easily place the lock of hair C inside the device 1, both between the motorized roller 3 and the pressing roller 17 on the one hand and between the first and second pressure surfaces on the other hand, as well as between the teeth of the combing device 22.
  • the lock C will then scroll at an appropriate speed through the combing device 22, then into the clamping device 6 (between the pressure surfaces 7, 8) which appropriately grips the hair to straighten the lock C in a particularly durable manner , fast and automatic.
