  • the pinching force exerted, at the level of an epilation forceps 12, by the second jaw 11 movable against the first fixed jaw 10 is advantageously a function of a calibration of the elastic return member 22 It is therefore possible to choose or adjust the tare of the elastic return member 22 so that the latter exerts a gripping force sufficient to effectively grip a hair to be torn off and not to let it slip during the tearing movement. , but not too important however in order to avoid breaking the hair when pinching it.
  • the roller 1 can comprise a plurality of locking members.
  • elastic return 22 separate, each of them being provided to return only one of said second movable jaws 11 from the open position.
  • the clamping forces are then generated independently on each epilation pliers 12, which guarantees good retention of the hair to be pulled out whatever the situation on the other epilation pliers 12.

  • the central shaft 16 then has an asymmetric shape at the circumference portion corresponding to said opening zone 26.
  • the central shaft 16 advantageously forms an eccentric hub ( or camshaft), intended to cooperate with the beads 24 (which then form followers) of the individual opening means of the second movable jaws 11, to transform a rotational movement of the main body 2 of the roller 1 around the shaft central 16 and along the axis of rotation AA 'in a translational movement of the beads 24 and pivoting of the second jaws 11 movable about their respective pivot axis CC'.
  • said first and second surface portions 25, 26 of the central shaft 16 preferably extend along substantially the entire length of the main body 2 of the roller 1, which makes it possible to simplify the design of the operating means and of the central shaft 16.
  • the central shaft 16 in effect then forms a single cam shaft.
  • the first portion 25 of substantially cylindrical surface of the central shaft 16 extends along substantially the entire length of the main body 2, while the second portion 26 of surface extends along the axis AA 'in a discontinuous manner so as to form on the surface of the central shaft 16 a plurality of protuberances distinct each intended to come into contact opposite a tweezer 12 of epilation.
  • the central shaft 16 would then form a multiple camshaft.
  • the maneuvering means for controlling the movement of the second movable jaws 11 comprise, as proposed above, a plurality of distinct elastic return members 22, each associated with one of said second jaws 11 movable to elastically recall it, automatically, from its open position to its closed position.
  • these elastic return members 22 are formed of compression springs 22 (or coil springs), which are each positioned between the rocker 23 of a second movable jaw 11 and the main body 2 of the roller 1.
  • each spring 22 could be arranged between a second movable jaw 11 and one of the lateral roller elements 3A, 3B and central 4A, 4B, 4C forming the main body 2 of the roller 1.
  • each spring 22 would be in direct contact on the one hand with a lateral surface of the second movable jaw 11 to push it back towards the corresponding first jaw 10 and, on the other hand, with an opposite surface belonging to one of the elements of side rollers 3A, 3B and central 4A, 4B, 4C.
  • other suitable types of elastic return members and other mounting configurations of the latter could be envisaged to obtain the desired effect.
  • leaf springs placed indifferently in the same place as the coil springs or elsewhere. Compression springs can be replaced by tension springs with reverse operation where when tilting the springs are stretched.
  • the epilator 12 passes over the second portion 26 of surface forming a protuberance (opening zone) of the central shaft 16, the bead 24 of the rocker 23 of the opening means of the second movable jaw 11 comes into contact with said opening zone 26.
  • This causes the tilting of the second jaw 11 movable, along the pivot axis C-C ', and maintaining the latter in its open position for a certain time.
  • the epilator 12 leaves the opening zone 26 and passes over the first surface portion 25 (or closing zone) of the shaft 16, the bead 24 is brought into contact with said closing zone 25. under the effect of the action of the spring 22. This results in the tilting of the second movable jaw 11, along the pivot axis C-C ', and the maintenance of the latter in its closed position for a certain time.
  • the profile (seen in radial section) of the second surface portion 26 of the central shaft 16 can be modulated so as to produce more or less progressive opening and closing movements of the epilation pliers 12.
  • the profile of the second portion 26 begins (when following it from left to right, that is to say here in the intended direction of rotation of the roller 1) with a gentle slope to generate a movement of gradual opening of the clamps 12, followed by a plate for holding the second movable jaws 11 (and therefore the clamps 12) in the open position, and ends with a relatively steep downward slope in order to allow the clamps 12 to close quickly to ensure good hair removal efficiency.
  • the epilation roller 1 is designed to be driven by the motor of the epilator at a speed of approximately 1,500 revolutions per minute (rpm).
  • said first and second surface portions 25, 26 of the central shaft 16 are defined by one and the same monolithic part, for example made of plastic. According to another more advantageous variant, adopted in the embodiment illustrated in the figures, said first and second surface portions 25, 26 of the central shaft 16 are, on the contrary, defined by at least two distinct parts.
  • the first portion 25 of substantially cylindrical surface of the central shaft 16 is preferably defined by an elongated main shaft part 28, advantageously monolithic, within which is formed a housing 29 configured to receive tightly, sliding in a direction normal to the axis of extension BB 'of the central shaft 16, one or more additional shaft parts 30A, 30B (for example, two) which define (s) t in turn (s) the second portion 26 surface of the shaft 16.
  • One or more compression springs 31 are arranged between the bottom of the housing 29 formed in the main shaft part 28 d 'on the one hand and the additional shaft part (s) 30A, 30B on the other hand.
  • centering studs can moreover advantageously be provided, both on the bottom of the housing 29 and on the additional shaft parts 30A, 30B, to hold the springs 31 in position and guide them.
  • the shaft part or parts 30A, 30B are advantageously mounted in suspension within the main shaft part 28.
  • Such a design advantageously makes it possible to guarantee a continuous, permanent support of the beads 24 against the second surface portion 26 of the central shaft 16 in operation of the roller 1, by compensating for any dimensional variations of the parts forming the central shaft 16.
  • this design advantageously dampens part of the shock associated with the sudden contacting of the beads 24 with the second portion 26 of the surface of the central shaft 16, so as to reduce the wear in particular of the beads 24 and of the second portion 26 of the surface of the shaft central 16, and to limit the noise and vibrations generated during operation of the roller 1.
