Definitions

  • the present invention relates to small depilatory devices capable of being held in the hand to remove excess hair.
  • this device For pulling out the hairs to be eliminated, this device comprises a set of two gripping jaws animated by an alternating translational movement along an axis parallel to the facing edges of these jaws, these jaws being also actuated by control means. likely to successively cause the spacing and tightening of the edges of these jaws during their movement in one direction and the other.
  • This device is completed by a protective grid placed above the two clamping jaws. This grid has a series of slots which extend perpendicular to the clamping plane of the two jaws. In addition, on its internal face, this grid has in its middle a rib which extends opposite this same clamping plane.
  • this device aims to provide an improved device of the type in question in which the drawbacks explained above are eliminated.
  • this device is designed so as to be devoid of any protective grid and to have an increased capacity for pinching the hairs to be plucked.
  • This device is characterized in that: - the clamping jaws are constituted by a series of blades placed one next to the other with their edges arranged in parallel, to form, in groups of two, a plurality of gripping and tearing pliers, these blades being mounted on a support animated by an alternative translational movement along an axis parallel to the edges thereof, these blades are coupled with one or more transverse actuation bars which are capable of successively causing the spacing and tightening of the edges of two adjacent blades forming a clamp, and this by transverse displacement of these bars in one direction and in the other, - These bars are themselves actuated by control means acting on them during the movement of the assembly in translation.
  • the pinching blades are pivotally mounted at their feet, that is to say at the place of their edge opposite their clamping edge, and this on the common support of all these blades, the actuating bars being able to cause the pivoting of these blades alternately in one direction and in the other so as to ensure the clamping of the edges of two adjacent blades in order to pinch the hairs engaged between them.
  • the pinching blades are carried by the control bars thereof instead of being simply actuated by the latter.
  • the working head of the device shown by way of example in FIGS. 1 to 4 comprises a rigid body 1 in the general shape of a bowl which is attached to the end of a small box 2 containing an electric drive motor. This case can be held by hand to move the working head in contact with the skin.
  • the members for removing the hairs to be removed consist of a series of thin blades, alternately 3a and 3b which are intended to form, in groups of two, a plurality of pliers, one of the pliers thus constituted by two blades neighboring 3a and 3b is also shown in isolation in Figure 6. These blades are placed one after the other having their clamping edges 4a or 4b arranged in parallel.
  • the transverse branch of this support is disposed against the bottom of the bowl 6 provided in the body 1 of the working head.
  • the lateral branches 7 of this support they are placed against the corresponding walls of this same bowl.
  • the support thus formed has a width less than that of the bowl 6 and it is mounted movable along an axis X-Y parallel to the edges 4a and 4b of the nipping blades.
  • This support is driven by an alternative movement of translation in one direction and in the other along this axis (see arrow F). Its training is ensured by means of appropriate mechanical means which are not shown.
  • balls 8 are advantageously interposed between the latter and the corresponding walls of the bowl 6, these balls being placed in complementary grooves.
  • clamping edges 4a and 4b of the clamping blades are flush with the plane YY ′ on which the edges of the body 1 of the working head are located as well as the edges of the support 5. It is therefore the plane device.
  • the clamping edges of the pinching blades could possibly be slightly projecting or, on the contrary, slightly recessed with respect to this plane.
  • the pinching blades 3a and 3b are pivotally mounted at their feet, that is to say at the location of their edge opposite their clamping edge 4a and 4b.
  • the edges 9a and 9b of two complementary blades 3a and 3b, which together form a gripper, are engaged in the same groove 10 provided in the bottom of the support 5.
  • the latter thus comprises a series of such grooves which extend parallel to the XX ′ axis. Thanks to this arrangement, the blades 3a and 3b can pivot between an open position shown in FIG. 3 and a closed position illustrated in FIG. 4.
  • the pivoting of these blades, alternately in one direction and in the other, is controlled by two actuating bars 11a and 11b. These two bars are placed one against the other and they are engaged together inside an opening 12 made in the different blades 3a and 3b.
  • the arrangement is such that the bar 11a is coupled with all the blades 3a while the bar 11b is coupled with all the blades 3b.
  • the openings 12a and 12b of the blades 3a and 3b have a different contour to each present alternately a tooth 21a or 21b capable of being engaged in a groove 13a of the bar 11a or a groove 13b of the bar 11b.
  • actuating head 14a or 14b At one end of the two bars, one of them has an actuating head 14a or 14b. This is slidably mounted inside an opening 15a or 15b made in the corresponding side of the mobile support 5. In normal position, these two heads protrude slightly outside the sides of this support, as shown in the figures 1 and 2, elastic return means then tending to keep the nip blades in the open position.
  • the actuating heads 14a and 14b of the two control bars then protrude inside two recesses 16 provided on each side of the body of the working head.
  • control means having a fixed position and which are capable of acting on the actuation heads 14a and 14b of the two bars 11a and 11b to make them slide in the opposite direction according to the arrows F1 and F2.
  • these control means consist of two rollers 17a and 17b whose axes are pushed by springs 18 in the direction of the sides 7 of the mobile support 5.
  • the pinch blades can advantageously be made of metal or very rigid plastic. Instead of the two blades of the same clamp being independent of one another, they can be constituted by a single piece folded back on itself in the articulation zone corresponding to the edges 9a and 9b. They can then remain open in the rest state under the simple effect of the elasticity of the part thus formed.
  • the clamping edges of the pinching blades may advantageously include a bent portion 19 so as to increase the effectiveness of the pinching.
  • the internal face of this part can be treated so as to have a roughness capable of preventing the hairs from sliding between the pinching blades.
  • the latter To compensate for irregularities in the shape of the push bars and the pinch blades, the latter must advantageously have a certain elasticity.
  • the mounting of the rollers 17a and 17b on springs 18 makes it possible to compensate for the possible wear of the moving parts.
  • the force of these springs must be equal to the sum of the forces necessary to close each pliers and the pinching forces necessary to trap the hairs to be plucked in these pliers.
  • the efficiency of the present device is considerably increased compared to previous devices of the same type. This is due in the first place to the presence of a multitude of pliers instead of a single set of two jaws. Moreover, the production of each of these pliers by means of two thin blades makes it possible to provide a high number of such pliers for a limited space corresponding to the usual dimensions of the working head of a depilatory appliance. All other things being equal, the efficiency of the device according to the invention is multiplied in the ratio existing between the sum of the lengths of the different pliers existing in this device and the length of the single pliers of the previous devices mentioned above. . However, this ratio can be of the order of 10 for equal dimensions of overall dimensions.
  • the effectiveness of this device is also due to the removal of the protective grid usually provided on a device of this kind.
  • This removal is made possible by the fact that the pinch blades are in high number and very close to each other. This avoids any risk of skin engagement between these blades, so that the presence of a protective grid is made perfectly useless.
  • the removal of such a grid makes it possible to avoid the risks of shearing of the bristles between the latter and the pliers.
  • this removal also allows the clamping edges of the pliers to be brought as close as possible to the skin, so that the hairs are gripped close to the skin, which avoids the risks of breakage.
  • FIG. 8 represents an alternative embodiment of the control strips of the nipping blades.
  • the two corresponding bars 11c and 11d are nested one inside the other.
  • one has an elongated U-shape and the other is engaged between the two branches of this U.
  • these bars have actuation heads 14c and 14d at both ends .
  • this modification of the control bars results in a modification of the openings provided in the nip blades. Indeed, in such a case, these openings must affect the shape of the openings 12c and 12d shown in FIGS. 10 and 10bis in order to include teeth 21c and 21d capable of being hooked in the grooves provided on either of the two bars 11c and 11d.
  • the pinch blades 3a and 3b could be at an intermediate point of their height. Furthermore, instead of being pivotally mounted on the mobile support 5 and only coupled with the control bars, these pinching blades could be carried alternately by one and the other of these two bars. In such a case, the gripping and opening of the gripping pliers would also be obtained by movements in the opposite direction of the complementary blades constituting these. However, these would then be translational movements and no longer pivoting movements. But the end result would be the same.
  • rollers 17a and 17b controlling the closing of the pliers could be replaced by other members capable of performing the same role. These members could possibly consist of ramps ensuring the closing of the pliers over a greater length of the stroke of the mobile assembly formed by the support 5 and by these blades.
  • the edges of the body 1 of the working head may have on the side of the slots 20. But again many other variants can be provided for the present device .
  • pinching blades could pivot at an intermediate point of their length instead of pivoting at their feet, as provided in FIGS. 1 to 9.
  • their pivoting could be controlled by an actuation carried out at their feet, or in any other appropriate place by sliding bars similar to bars 11a and 11b, or by other suitable control means.
  • the pinching blades may not be pivotable, but be mounted movable in translation along the axis YY ', these blades being alternately movable in one direction and in the opposite direction, so that two neighboring blades successively perform a clamping movement. , then a spreading movement.
  • the blades of each series could be secured to a common support by forming with it a kind of one-piece comb, the two movable combs thus provided being nested one inside the other and driven by alternative movements of translation , in opposite directions to each other.
  • Figures 10 to 14 they represent yet another embodiment, in which the pinch jaws are made quite differently. Indeed, these are formed by bars cut from plates of elastic material, and this by practicing a series of parallel slots in such plates.
  • the plates 21 have the form of square or rectangular blocks and are housed in separate cells 26 provided in the movable support 23, and the bottom of which has a large opening 26a.
  • the movable support 23 has an elongated shape and it extends over the entire length of the corresponding end of the housing 27 of the device. As in the embodiment described above, this support is driven in an alternating translational movement, in one direction and in the other, along the axis ZZ ′. Its drive is provided by a movable arm 28 itself actuated by an appropriate mechanism. This mobile support is guided in these movements by balls 29 engaged in guide tracks 30 formed by grooves provided in the corresponding walls of the housing 27.
  • the slots 22 of these are freely open as shown in FIG. 10. Under these conditions, when the working head of the device is moved above the skin, the bristles to be plucked can engage inside these slots during the translational movement of the mobile assembly formed by the support 23 and the various plates 21.
  • mechanical means are provided capable of causing, at a time determined, the contraction of the elastic plates 21 on themselves, and consequently the closing of the slots 22 to pinch the hairs between the corresponding bars 25 which thus form pinch jaws.
  • the means thus provided include a crossbar 31 parallel to the movable support 23 and coupled in translation therewith.
  • This bar is coupled to each of the elastic plates 21 by means of a connecting bar 32.
  • the ends of this transverse bar protrude beyond the corresponding ends of the mobile support 23 and each of them carries a roller 33 engaged in a raceway formed by a groove 34 formed in the corresponding wall of the housing 27.
  • each of these raceways is arranged to constitute a cam capable of controlling the movement of the crossbar 31 in the direction of the arrow F3 in FIG. 12, that is to say in the opposite direction from the surface of work of the device, and this when the mobile support 23 reaches the middle of its travel during its translation in one direction and in the other.
  • the guide tracks 34 have a bent shape so as to include, in their middle, a part offset in the direction of the arrow F3.
  • the transverse bar 31 is caused to exert traction on the various elastic plates 21 in the direction of the arrow F3.
  • This traction then causes the deformation of each of the plates 21 which is caused to contract thus on itself.
  • This causes the bars 25 to be tightened against each other and consequently the hairs which are at this time engaged between these bars to be pinched.
  • the pulling out of these bristles is carried out in the same way as in the previous embodiment, that is to say under the effect of the translational movement of the movable support 23 in one direction and in the other.
  • this variant has the advantage of greater simplicity. This is obviously due to the fact that instead of being constituted by separate blades mounted on a common support, the pinch jaws are formed in plates of elastic material which simply have parallel slots giving rise to pinch jaws arranged side by side with a small gap between them. This therefore results in a very great simplification of the mechanism, and consequently a significant reduction in the cost price.
  • the subject of the invention is not only such an appliance for depilation in its together, but also the working head of this device, this head then being designed to be fitted to the housing of an already existing device comprising a drive motor and a mechanism capable of ensuring the reciprocating translational movement of the mobile support 5 pinch blades.
