Definitions

  • the present invention relates to electric depilatory devices, more particularly to small depilatory devices capable of being held in the hand, usable for cosmetic applications.
  • Patent FR-2,556,939 describes an epilating appliance comprising a housing, a roller mounted to rotate behind a slot or a grid provided in one end of the housing, and formed of a series of discs, and a series of parallel pinching blades between them, engaged between the rotating discs, carried by a support mounted movable parallel to the shaft of the discs. The support moves periodically so as to apply the nip blades against the rotating discs to trap the hairs and pull them out by rotating the discs.
  • Patent application FR-2 626 790 describes a similar system in which blades are mounted mobile on a drive shaft so as to be able to pivot about an axis perpendicular to this shaft and to be clamped against each other in groups two to pinch the hairs between these blades to pluck them.
  • European patent 0 101 656 describes a hair removal device comprising a helical spring formed by a set of turns, the spring including a curved part for retaining the bristles arranged to define a convex side where the turns are separated, and a concave side corresponding to this where the turns are tightened together, the rotational movement of the helical spring producing a continuous movement of the turns from a spacing orientation on the convex side to a tightening orientation on the concave side to retain and pluck the hairs of the subject's skin.
  • the object of the present invention is therefore to provide a hair removal device which ensures simple and effective pulling of the hairs while avoiding the drawbacks of the prior art.
  • a hair removal device with electric power supply characterized in that it comprises, in a portable housing held in the hand, a stator integral with the housing provided with actuating cams, and a rotor driven by an electric motor, rotating about an axis perpendicular to the skin to be depilated and comprising a grid which comprises at least two coaxial annular elements provided with blades for clamping the bristles against the wall of at least one of the annular elements, said clamping blades cooperating with said actuating cams to effect periodic displacement relative to said wall during the rotation of the rotor.
  • the grid comprises spacers located between two coaxial annular elements, substantially halfway up the walls of said coaxial annular elements.
  • the annular elements taken two by two define between them an annular channel in which said blades are arranged. in the spaces between the spacers and in that the blades have a height substantially equal to that of the walls of the annular elements, and include a zone of nipping and tearing of the hairs facing the skin to be depilated and a cooperating actuation zone with the cams provided on the stator and said blades preferably have a curved shape and are held by one of their ends on an annular element, their opposite end being applied under the effect of their own elasticity against the wall of the neighboring annular element.
  • stator cams are arranged in concentric rings at radial locations located in the corresponding channels of the grid and preferably have variable profiles, their angular arrangement conferring a phase shift in the movement of the blades which ensures a uniform distribution of the forces over the periphery of the rotor during operation.
  • the grid comprises at least three coaxial annular elements, the intermediate annular element of which is provided with Y-shaped clamping blades, the axis of each of the Y-shaped blades being held on the intermediate annular element, the wings of the Y deviating respectively from each side of the intermediate annular element and their ends being applied to the walls of said other annular elements and in that the wings of the Y are actuated by cams belonging to neighboring crowns.
  • the walls of the coaxial annular elements have corrugations adap-ted to match the curved shape of the blades.
  • the hair removal device comprises a box 1 capable of being held in the hand, in which is placed a small electric motor, not shown, connected to the mains by means of a transformer or powered by a battery.
  • a small electric motor not shown
  • the putting into operation of this motor can be controlled by a push button 2 projecting from one of the sides of the case.
  • the hair removal device comprises a stator 3 provided with cams 4 integral with it, pierced in its center to allow the drive mechanism of a rotor 5 to pass.
  • the rotor 5 is driven by the electric motor rotating around 'an axis perpendicular to the skin to be depilated.
  • the useful surface of the rotor 5 coming applies to the contact of the skin to be depilated can be flat, frustoconical or in a sphere cap as shown in fig. 1.
  • the rotor is formed of a grid 6 comprising coaxial annular elements 7, delimiting channels 8 in which are arranged clamping blades 9 of the bristles to be removed.
  • the walls of the annular elements 7 are close enough to prevent the skin from getting into it.
  • the rotor 5 cooperates during its rotation with the cams 4 of the stator 3.
  • the grid 6 of the rotor has radial spacers 10 located in the channels 8 between two adjacent annular elements 7 approximately halfway up the wall of the annular elements 7 and has a cross section in H when the cutting plane passes through a spacer (Fig. 3).
  • the clamping blades 9 are arranged in the channels 8 in the spaces between the spacers 10.
  • the blades 9 comprise a nipping and plucking area 12 of the hairs facing the skin to be depilated and an actuation area 13 facing the stator, which cooperates with the actuating cams 4. They have a height substantially equal to that of the walls of the annular elements 7 so that the edge of these blades 9 is flush with the skin when the latter is pressed against the grid 6 rotor. However, the height of the blades 9 may be slightly less than that of the walls of the annular elements 7 on the side of the nipping and tearing zone 12 to take account of the slight bulging of the skin when the rotor grid is applied against it. this.
  • the blades 9 have an advantageously curved shape as shown in FIG. 3 and are held by one of their ends 14 on the annular element 7, by means of tongues 15 provided with an axis 15a as shown in FIG. 3 or may comprise at their fixing end a cylindrical rib of small diameter which allows the engagement by snap-fastening of the blade 9 in a corresponding slot made in the wall of the annular element 7.
  • each of the blades 9 is applied under the effect of its own elasticity against the wall of the neighboring annular element 7.
  • FIG. 2 all the blades 9 located in the same channel 8 fixed on the same annular element 7 and coming to bear against the adjacent annular element 7.
  • the annular elements 7 advantageously comprise recesses 17, produced in the part of the annular elements opposite to that against which the blades 9 come to bear. These recesses are advantageously furnished with brushes 18 so as to facilitate the straightening of the hairs applied against the skin by the song of the annular element 7.
  • Brushes 19 the bristles of which are oriented parallel to the wall of the annular elements can also be provided on the grid spacers on the one hand to straighten the hairs to be removed before their pulling out and on the other hand to retain the hairs pulled out.
  • the brushes 18 provided in the recesses 17 of the annular elements and those 19 disposed on the spacers 10 further contribute to exerting pressure on the skin to be depilated to force it to remain as flat and taut as possible despite the pressing pressure exerted by the user.
  • the grid 6 and the clamping blades 9 are advantageously made of an elastic material such as a synthetic plastic material possibly added with fillers, such as fiberglass or the like.
  • the blades 9 carried by a determined annular element 7 as well as the spacers 10 located between these blades are molded with this annular element.
  • the annular elements with their blades and the corresponding spacers are then assembled and, all of the elements forming the grid are joined by welding or heat-sealing at the level of the spacers.
  • the blades 9 as well as the walls of the annular elements 7 are coated with a non-slip material such as rubber to improve the grip of the hairs to be removed, while reducing the noise caused by the movement of the blades 9 on the walls of the elements. ring fingers 7.
  • the cams have different profiles such as a portion of a sphere, an ellipse or the like.
  • the actuating cams 4 of the stator 3 are arranged in rings concentric at radial locations located in the corresponding channels of the grid 6 so that during the rotation of the rotor, they are opposite the nip and tear-off zones 12 of the blades 9.
  • the cams 4 are advantageously produced by molding with the stator 3 and are made of a material chosen for its properties of resistance to wear and low coefficient of friction.
  • the epilating device of the invention is applied to the surface of the skin to be epilated so that the useful surface of the rotor 5 is in contact with the latter.
  • the blades 9 come into contact through their actuation zone 13 with the cams 4 of the stator 3 as shown in Figures 4 to 6.
  • the cams 4 then act periodically on the blades 9 which they separate from the wall of the annular element 7 against which they are applied, as indicated in FIG. 5.
  • the blades 7 are then released and folded down under the effect of their own elasticity towards the wall of the annular element 7 against which they are applied again, as shown in FIG. 6.
  • each crown comprising cams of identical shape and size, the shape and size being variable from one crown to another.
  • the cams 4 are different from each other on the same ring so that in the same channel 8 of the corresponding rotor 5 the blades 9 are released with force and a different amplitude in order to vary the pinching mode of the bristles applied against the same annular element 7.
  • the angular arrangement of the cams 4 is produced in such a way that the blades 9 located in the same channel are at a given moment in different phases of their spacing so that the phase shift obtained in the displacement of these allows a homogeneous distribution of the forces on the periphery of the rotor 5 and a noise substantially attenuated compared to the noise that would produce the simultaneous displacement of the blades 9 against the wall of the annular element 7 on which they are applied.
  • the grid 6 comprises at least three coaxial annular elements 7, defining at least two coaxial channels 8.
  • the intermediate annular element 7 is provided with clamping blades 9 ′ having a Y shape maintained at the central annular element for example by means of a narrow tongue 22 intended to maintain the blades on the wall of the element annular 7 intermediate in recesses of the element 7 provided for this purpose, and comprising two wings 23 having a height substantially identical to that of the wall of the annular elements 7 adjacent to the Y and deviating respectively from either side of the intermediate annular element 7 to be applied by their ends 25 to the walls of the annular elements 7 located on either side of the intermediate annular element.
  • the action of the cams 4 is then adapted to a simultaneous movement or not of the two wings 23 of the Y towards one another.
  • the clamping blades 9 ′ can pivot around an axis 26.
  • the energy stored by the blade 9 ′ during the actuation of one of the wings 23 of the Y is then subsequently recovered when it returns. in its initial position to contribute to the actuation of the other wing 23 which makes it possible to reduce the engine torque which must be supplied.
  • This variant embodiment is particularly suitable for devices using a low energy source such as a cell or battery.
  • the advantage of the present invention is therefore to propose, in an apparatus which can be operated in a single hand, a variety of modes of pinching and pulling of significantly different hairs, without particular training of the manipulator, without the need to adjust the device, without reducing the efficiency and speed of use of the device, being given the large amount of pinching it is possible to obtain on such a surface while leaving a small number of recalcitrant hairs after treatment.
