Definitions

  • the present invention relates to hair removal devices which are capable of being held in the hand in order to move them over the skin to remove unwanted hair.
  • French patent application 2 307 491 describes an apparatus comprising two pairs of rollers rotating in opposite directions and which are intended to ensure the pulling out of the bristles engaging between them.
  • the effectiveness of this device is limited. This is due to the nature of the organs used to pull the hairs. Indeed, the latter are not gripped sufficiently efficiently between the rotating rollers.
  • the point where the bristles are actually gripped between the two rollers that is to say the point of contact between them, is necessarily located far behind the corresponding end of the housing of the apparatus.
  • depilatory devices which also include rotary bristles for removing hairs, for example the device described in French patent application 2,334,320, as well as that described in French application 2,425,822.
  • the efficiency of these devices also leaves something to be desired.
  • the cost price of these devices is relatively high, taking into account the presence of the mechanisms necessary to ensure the rotational drive of the members for removing the hairs to be eliminated.
  • the aim of the present invention is to produce a small device intended for the same use, but which is designed so as to present optimum efficiency and nevertheless to include a limited cost price.
  • this device is essentially characterized in that the tearing members provided therein consist of two jaws arranged one opposite the other and mounted movable in the same plane while being and coupled with a member drive capable of imparting to them an alternative translational movement along an axis parallel to the facing edges of these jaws, while guide means successively ensure the spacing and the tightening of these two jaws during their movement in one direction and in the other, the hairs trapped between the two jaws being torn off under the effect of the transverse displacement of the latter while they are held tight against one another.
  • the present apparatus comprises a work head of very simple design and which does not include complicated or expensive mechanisms.
  • the movable jaws provided in this working head can be driven in movement by a drive finger animated by an alternative translational movement and this, by a very simple design mechanism of the type of those provided on many electric razors.
  • the working head of the present device constitutes in itself one of the objects of the present invention since this head can be adapted on the drive finger provided in certain already existing devices.
  • this work head has a very high efficiency. Indeed, the hairs to be plucked can easily engage between the two movable jaws, when the latter are in their spacing position during their displacement in one direction. Then they are strongly pinched between these jaws during their tightening, then torn off under the effect of the traction exerted on them by the jaws during their travel of movement in opposite direction.
  • the tearing jaws are formed by the bent ends of two arms, or two pairs of arms, articulated one on the other at an intermediate point of their length, in the manner of the two branches of a collet, and the opposite ends of which are arranged in contact with fixed cams, capable of controlling the movement of the tearing jaws towards and away during the translation of the assembly in one direction and in the other.
  • the device represented in FIGS. 1 to 5 comprises a small box 1 capable of being held in the hand, and inside which is provided an electric motor (not shown) supplied either by a connection to the electrical current distribution sector. , either by built-in batteries or rechargeable batteries.
  • this motor imparts an alternating translational movement to a drive arm or finger 3 whose free end is located opposite the 'one of the housing ends 1.
  • This comprises two movable jaws 5 tearing arranged one opposite the other.
  • These jaws are formed by the bent ends of two arms 20 articulated one on the other, at an intermediate point of their length, in the manner of the two arms of a collet.
  • these two arms comprise, on their internal face, a series of knuckles 21 inside which is hinged a hinge pin 22.
  • the ends of the latter are engaged in bores 23 formed in the body 24 of the working head of the device.
  • the axis 22 is retained in place by the curved ends 25 of a protective grid 26 disposed above the two tearing jaws 5.
  • the two articulated arms 20 In their part adjoining the jaws 5, the two articulated arms 20 have a width equal to these. However, in their opposite part these two arms each have a cutout 27 which leaves only an end finger 28 on each of these arms. Fingers are engaged inside grooves 29 provided in the body 24 of the working head and the walls of which are capable of serving as control cams capable of imparting the desired pivoting movements of the arms 20, in one direction and in the other to successively ensure the tightening and the spacing of the lifting jaws 5 during the translational movements of the mobile assembly.
  • this drive member carries a transverse tab 30 which is engaged inside notches 31 formed in the articulated arms 20 (see FIG. 4).
  • Each groove 29, the walls of which act as control cams, has a first rectilinear part 29a parallel to the XY axis of translation of the movable assembly and a second part 29b, of shorter length, which is bent in the direction of this axis.
  • this second part is able to bring the extreme fingers 29 of the two articulated arms closer together and consequently the spacing of the clamping jaws 5. Consequently, the engagement of a bristle to be pulled out P takes place while the fingers 28 of the articulated arms travel, in one direction and in the other, the bent parts 29b of the two grooves 29.
  • this first part has a much greater length so that the hairs trapped between the jaws 5 are pulled over a sufficient distance to cause their pulling out.
  • the hairs thus plucked out are released when the end fingers 28 return inside the bent parts 29b of the two grooves 29, other bristles then engaging at the same time between the jaws 5 and then being plucked out, and so on. .
  • the position of the hinge pin 22, on the two articulated arms 20, is determined so that the latter are able to play the role of levers amplifying the clamping force of the lifting jaws 5 when they are brought together .
  • This makes it possible to obtain perfect confinement of the bristles between the two jaws 5. However, this result is obtained with less energy consumption than in the case of the first embodiment described.
  • the working head of the present apparatus can be subject to various modifications and other embodiments.
  • the grooves 29, serving as control cams for the articulated arms could comprise an inclined part 29b at each end.
  • the spacing of the clamping jaws 5 would be effected at each end of the travel of the movable assembly in one direction and in the other, and two successive stripping operations would take place respectively during the movement of the fingers. 28 in one direction, then in the opposite direction.
  • control cams could consist of two protrusions against which the two end fingers 28 would be kept applied, for example by means of one or more return springs provided between the arms 20.
  • the walls of these protrusions would comprise, as for the grooves 29, a first part of great length parallel to the axis XY, and a second shorter part bent in the direction of this axis. Consequently, the functions provided by these cams would be the same as before.
  • the lifting jaws 5 could be carried by two pairs of articulated arms provided at their ends and which would be mounted in the same way so that the arms 20 and also controlled by cams successively ensuring the tightening and spacing of the tearing jaws during the translational movements of the movable assembly in one direction and in the other.
  • the apparatus according to the invention has the advantage of being extremely effective. This is due to the very nature of the pinching and lifting bodies. Indeed, these organs are constituted by two jaws which are arranged in the immediate vicinity of the skin, so that the hairs are gripped very close to their roots and not near their end. Consequently, the hairs are plucked out and not broken.
  • the effectiveness of the present device is optimum both with regard to the pinching of the hairs to be removed and their pulling out.
  • the nature of the movements thus provided also has the advantage that the mechanism of the working head of the present apparatus is particularly simple and inexpensive. Indeed, the jaws of this working head can be very simply driven by a drive finger animated by an alternative translational movement in the manner of the drive fingers existing in certain electric razors. Moreover, this makes it possible to produce the present device from certain already existing elements, initially manufactured for the production of electric razors, only the working head being different. Possibly it would even be possible to make a device that can be used either as an electric razor or an epilator, by providing two separate working heads removably mounted and one of which could serve as a razor and the other as an epilator in accordance with present invention.
  • the working head of the present epilating device constitutes in itself one of the objects of the present invention.
  • this work head could be marketed independently to be adapted to certain electric shavers or the like.
