  • the first position of the control means 12 corresponds, in the illustrated embodiment, to the coupled configuration of the complementary coupling parts 16, 17, while its second position of the control means 12 corresponds when it to the uncoupled configuration, said first position therefore being a stable return position while the second position is an unstable position.
  • first and second complementary coupling parts 16, 17 When the first and second complementary coupling parts 16, 17 are in coupled configuration, said motor and receiver shafts 3A, 4A are substantially aligned (cf. figures 2 And 3 ), while when said first and second complementary coupling parts 16, 17 are in uncoupled configuration, said motor and receiver shafts 3A, 4A are substantially misaligned (cf. figures 5 to 7 ).
  • the first and second complementary coupling parts 16, 17 are, in their uncoupled configuration, not only out of contact with each other, but also offset, due to the aforementioned offset of the motor and receiver shafts 3A, 4A, which are no longer coaxial in uncoupled configuration.
  • This offset of the motor and receiver shafts 3A, 4A, and therefore of the first and second complementary coupling parts 16, 17 which they carry respectively, further reinforces the safety of use by guaranteeing a complete kinematic break, since the first and second complementary coupling parts 16, 17 are several millimeters apart.
  • the kinematic break is quick to implement since the rotational drive is immediately interrupted by the misalignment of the motor and receiver shafts 3A, 4A, independently of any mechanical part (spring for example).
  • Such speed of uncoupling is particularly useful and sought after in the event of a knot in the hair, to prevent the user from feeling like their hair is being pulled or ripped out.
  • the offset of the motor and receiver shafts 3A, 4A is a simple solution for uncoupling the first and second complementary coupling parts 16, 17 since this offset can remarkably be linked to the movement of other parts of the device. The safety and reliability of the device are thus remarkably improved.
  • a circular translation movement if preferred, is however not obligatory and it is for example alternatively possible to resort to two successive rectilinear translation movements in respective directions which are perpendicular to each other.
  • the torque limiter is therefore advantageously designed to play its role only when the first and second complementary coupling parts 16, 17 are coupled. In this case, it makes it possible to interrupt automatically (without user intervention) the transmission between the motor 3 and the drive means 4 when the threshold value is reached or exceeded, which can occur when, for example, the hair of the user have knots or in the event of inappropriate use of the device 1.
  • the torque limiter aims to prevent any risk for the user or the motor 3 when the drive means 4 sets the wick in motion. hair C , the first and second complementary coupling parts 16, 17 cooperating to transmit to the receiver shaft 4A the rotary movement of the motor shaft 3A.
  • 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 torque limiter can for example connect two portions of the motor shaft 3A together, or two portions of the receiver shaft 4.
  • the first and second complementary parts coupling 16, 17 themselves form, in their coupled configuration, said torque limiter.
  • said coupling parts 16, 17 are respectively formed by a first and a second disc intended to come into facial contact as illustrated, to form both a friction clutch (in this case disc/disc type) and a torque limiter (for example by friction).
  • said first and second complementary coupling parts 16, 17 are inter-engaged by adhesion (to form a friction torque limiter) or by obstacle (to form a frictionless torque limiter, for example toothed, ball or roller) thus forming the aforementioned torque limiter.
  • adhesion to form a friction torque limiter
  • obstacle to form a frictionless torque limiter, for example toothed, ball or roller
  • the invention makes it possible, in this particularly advantageous embodiment, to guarantee a particularly high level of security by combining the removal of contact from the complementary coupling parts 16, 17, preferably under the direct control of the user (for example manipulation of the control means 12) and an automatic torque limiter function, which is not controlled directly by the user but depends on the conditions of use of the drive means 4 and the motor 3.
  • the main body 2 also includes combing means 21 of said strand of hair C intended to be driven by the drive means 4, said combing means 21 being advantageously arranged upstream of the clamping device 5 relative to the direction scrolling of said wick C.
  • the combing means 21 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 21 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 6A, 7A.
  • the combing means 21 thus allows the lock C to be well spread between the jaws 6, 7 to promote its shaping by the heating jaws 6, 7.
  • the combing means 21 also provides a tensioning function of the lock of hair C , in particular by opposing a local resistance by friction to the movement of the lock of hair C towards the drive means 4.
  • Combing carried out by the combing means 21, however, increases the risk of malfunction of the device 1, because knots of hair can get stuck between the teeth of the combing means, causing resistance likely to damage the motor.
  • the implementation of a torque limiter as explained above, however, makes it possible to very significantly limit this risk.
  • the invention thus relates to a styling device 1 which is preferably specifically intended for straightening hair and whose closed position of the jaws 6, 7 corresponds to the natural configuration (rest configuration) of the device 1. In this natural position rest, the complementary coupling parts 16, 17 are in coupling configuration, ready to transmit the driving torque produced by the motor 3, the pressing means 41 occupying its close position while said device clamping 5 is in clamping configuration.
  • the control means 12 In this natural rest configuration of the device 1, the control means 12 is in its first position, which is advantageously an elastic return position. Exercising pressure on the control means 12, against the elastic return force which is constantly exerted on the latter, makes it possible to move the device 1 from its stable rest configuration to a open configuration unstable in which the device 1 is held by manual action of the user on the control means 12 to force the latter to occupy its second position.
  • the complementary coupling parts 16, 17 are in uncoupled configuration, the pressing means 41 is in the spaced position while the clamping device 5 is in the insertion configuration.
  • the device 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 drive means 4 is arranged close to the scalp while the combing means 21 is arranged opposite the drive means 4, furthest from the scalp.
  • the user then activates the control means 12 to thus force the device 1 to leave its normally closed configuration to reach its unstable open configuration.
  • the user can then move the device 1 to easily place the lock of hair C inside the device 1, both between the drive means 4 and the pressing means 41 on the one hand and between the first jaw 6 and the second jaw 7 on the other hand, as well as between the teeth of the combing device 21.
  • the user releases the control means 12 so that the device 1 is returned to its normally closed configuration, in which the motor 3 is then capable of driving the drive means 4.
  • the latter will then scroll at an appropriate speed the lock C in the combing device 21, then in the clamping device 5 which appropriately tightens the hair to straighten the lock C in a particularly durable, rapid and automatic manner.
