Definitions

  • the present invention relates to the technical field of hairdressing appliances such as curling irons or straighteners.
  • Such devices generally comprise two jaws at least one of which is heated and which are hinged together so as to be able to pinch a lock of hair to be shaped.
  • One of the jaws or both jaws are then heated directly or indirectly by an electric heating member whose temperature is regulated by a thermostatic system to reach a temperature determined according to a temperature value possibly selected by a user of the 'apparatus.
  • Such a type of hairdressing apparatus makes it possible with some practice to obtain a good smoothing result.
  • This good smoothing result is obtained by applying a significant pressure force to keep the jaws closed and apply sufficient pressure on the lock of hair to be treated. Possibly, the user can use both hands to increase this effort for a better result. In all cases, the maintenance of this significant pressure effort during the entire treatment cycle of the hair is painful and restrictive for the user. Laboratory tests have shown that the combination of the tension of the hair and the heat applied by the iron with a reasonable clamping pressure makes it possible to obtain a result equivalent or even better than that obtained with iron alone by applying a pressure more important.
  • the invention relates to a hairdressing appliance according to claim 1.
  • the friction bar may for example be designed so that in the closed position of the jaws, the traction zone has a coefficient of friction greater than the coefficient of friction of the treatment zone.
  • the difference in traction or friction allows a user, who has made sure to arrange the hairstyling device so that the treatment area is located between the traction zone and the scalp, to stretch the part of the hair located between the scalp and the traction zone and therefore in particular that located in the treatment zone, so that the heating of the hair in traction in the treatment zone makes it possible to obtain an optimal smoothing and very clearly superior to that which would result from a simple heating of the hair.
  • the possibility of adjusting the value of the withdrawal allows the user to adjust the intensity of the friction and therefore the tension exerted by the traction zone according to the desired result, its comfort or the quality hair to treat.
  • the adjustment means are preferably adapted to prevent the sliding of the friction bar relative to the adjacent working surface under the effect of the force exerted during the closing of the hairdressing apparatus on a lock of hair to treat.
  • the means for adjusting the withdrawal distance are adapted to allow a variation of the value of the withdrawal distance between 0.1 mm and 5 mm.
  • the friction bar is preferably located between the adjacent working surface and an edge of the first jaw and is thus offset laterally with respect to a longitudinal median plane of the jaw.
  • the relative movement between the friction bar and the adjacent work surface allowing adjustment of the withdrawal distance can be achieved in any suitable manner.
  • the friction bar is rigidly connected to the first jaw so as to have a fixed position relative to the latter.
  • the element of the second jaw intended to cooperate with the friction bar can be made in any suitable manner and for example be formed by a portion of the working surface of the second jaw.
  • the second jaw may also comprise at least one against-friction bar located opposite the friction bar of the first jaw and intended to cooperate with said friction bar.
  • the friction bar will then preferably define a substantially planar friction surface parallel to the adjacent working surface of the second jaw.
  • the friction surface of the counter bar can then be flush with the adjacent working surface or on the contrary be slightly protruding relative to the latter as is the case for the friction bar vis-à-vis the adjacent working surface. It may also be envisaged to implement on the second jaw means for adjusting the value of the shrinkage between the friction surface of the against bar and the adjacent working surface. These adjustment means can then be made as those implemented on the first jaw.
  • the friction bar can be heated by complementary electric heating means.
  • the friction bar may also be heated by the electrical heating means of the adjacent work surface.
  • the heating of the friction bar is not strictly necessary for the realization of a hairdressing apparatus according to the invention.
  • the friction bar can be made in any suitable manner.
  • the friction bar or the surface of the bar for friction in contact with the lock of hair may be composed or at least partially coated with a tensor material that can withstand heat such as for example a silicone.
  • the silicone layer may have a thickness of between 0.1 and 10 mm, it may have a hardness between 5 and 90 shores, preferably in a range between 40 and 50 shores, preferably equal to 46 salt A. Silicone is resistant to high temperature at least above 100 ° C, up to 150 ° C and up to about 270 ° C or even 300 ° C.
  • the silicone constituting the friction surface can be overmolded, crimped or engaged in a friction bar slide.
  • the silicone used aims to stretch, brake, evenly apply the lock of hair to be treated on the counter-support against the friction bar. Any material alternative to silicone and making it possible to achieve at least one of the three results mentioned can also be envisaged. These last remarks also apply to the counter-friction bar that can be made as the friction bar.
  • a hairdressing apparatus as illustrated in FIG. figure 1 and designated as a whole by the reference A, comprises two elongated jaws 1 and 2 of generally parallelepipedal shape and each extending along a longitudinal axis ⁇ , ⁇ '.
  • the jaws 1 and 2 are connected near one of their ends by a hinge or pivot link 4 axis ⁇ .
  • the jaws 1 and 2 are hinged together and movable between an open position O as illustrated in FIGS. Figures 1 and 2 , and a closed position F represented at figure 3 .
  • Each jaw 1 and 2 comprises, near an end opposite the link 4, a working surface respectively S 1 , S 2 .
  • Each working surface S 1 , S 2 is located opposite one another and extend over only a portion of the length of the jaws 1 and 2, so as to define in the closed position F a treatment zone T hair.
  • Each working surface S 1 and S 2 has, according to the example shown, a generally rectangular shape and is made of a thermally conductive material having a surface state adapted to be placed in contact with hair without the risk of damaging them.
  • each working surface S 1 , S 2 could for example be smooth by being polished or possibly covered with an enamel, a ceramic material, a polymer material with a low coefficient of friction or a low enamel coefficient of friction or a layer of glass.
  • the working surfaces S 1 and S 2 are formed by fixed smoothing plates respectively first 5 and second 6.
  • the first smoothing plate 5 extends over only a portion of the width of the first jaw while the second plate smoothing 6 extends over the entire width of the second jaw 2.
  • the two smoothing plates 5, 6 are both fixed rigidly on the corresponding jaw 1, 2.
  • the smoothing plates 5 and 6 are each associated with electric heating means 7 and 8 in contact with the rear surface of the corresponding plate, located opposite the working surface S 1 , S 2 .
  • the electric heating means 7, 8 can be made in any suitable manner such as for example in the form of a resistive heating element CTP or infrared emission.
  • the electric heating means 7, 8 are located inside the first 1 and second 2 jaws.
  • the heating means 7, 8 are for example designed to maintain a predetermined target temperature automatically.
  • the heating means 7, 8 could also be connected to control means not shown allowing a selection by a user of a set temperature.
  • the heating means and / or their control unit are supplied with electrical energy by a connecting cord which extends from one end of the second jaw 2 opposite to the working surface S 2 .
  • the power supply of the hairdressing apparatus A could also be provided by batteries or batteries arranged inside one and / or the other of the jaws 1 and 2.
  • the embodiments of FIG. heating means and the possible control unit are well known to those skilled in the art and therefore do not require further description in the context of the present invention.
  • the first jaw 1 comprises a friction bar 10 which extends along the left edge of the first smoothing plate 5 and more particularly between the edge of the smoothing plate 5 and the corresponding edge of the jaw 1
  • the friction bar 10 is formed by a carriage 11 movable in translation parallel to a normal plane N to the working surface S 1 .
  • the carriage 11 comprises opposite the first jaw 1 a silicone head 12 which is overmolded on the carriage 11 and which defines a substantially flat surface friction 13.
  • the friction bar 10 is furthermore made in such a way that the friction surface 13 projecting surface with respect to the working surface S 1 of the first plate 5.
  • the working surface S 1 is thus set back relative to the friction surface 13.
  • the value of the shrinkage R, measured between the plane of the working surface S 1 and a parallel plane passing through the friction surface 13, is for example between 0.1 mm and 5 mm.
  • the first jaw 1 further comprises means 20 for adjusting the withdrawal distance R interposed between the friction bar 10 and more particularly the carriage 11 and the first jaw 1.
  • the adjustment means 20 comprise a screw system which allows to continuously adjust the value of the withdrawal R between a minimum value for example of the order of 0.1 mm and a maximum value for example of the order of 1 mm.
  • the maximum and the minimum could have other values chosen in the range between 0.1 mm and 5 mm.
  • the friction bar 10 is adapted to cooperate with a facing element which is constituted in this case by the second smoothing plate 6.
  • the hairdressing apparatus A thus constituted is implemented in the following manner.
  • a user wishes to smooth a strand of hair M, he just close the apparatus A on said wick, as shown in FIG. figure 3 .
  • the user will then have made sure to place the friction bar 10 opposite the scalp C relative to the first smoothing plate 5.
  • the first 5 and second 6 smoothing plates define a zone of treatment T which has in cross section a general rectangular shape.
  • the friction bar 10 and the part facing the second smoothing plate 6 define a traction zone 16 which is narrower than the treatment zone because of the withdrawal R of the working surface S 1 with respect to the friction surface 13.
  • the pressure exerted on the lock of hair M is therefore greater in the traction region 16 than that exerted in the treatment zone T so that the friction at the level of the region 16 is greater than that of the treatment zone T.
  • This difference in friction is all the more accentuated that the silicone constituting the friction surface 13 has a coefficient of friction with the hair greater than that smoothing plates 5 and 6 whose working surface is preferably made of a material having a lower coefficient of friction than silicone.
  • the adjusting means 20 are preferably designed so that the friction bar does not move towards the jaw 1 under the effect of the pressure resulting from the closing of the hairdressing apparatus on the Wick M of hair to treat.
  • This anti-recoil effect is obtained, in the case of the example illustrated, thanks to the irreversible nature of the screw system forming the adjustment means 20.
  • the withdrawal distance, once set off, is constant or invariable during the hairstyle and use of the device.
  • the bar is not intended to move relative to the work area during styling.
  • the adjustment of the shrinkage R makes it possible to act on the distance between the two working surfaces so as to prefer either a heating rather by conduction in the context of a low value of the shrinkage R, or a heating rather by radiation in the case of a high value of the shrinkage R. It should be noted that the adjustment of the shrinkage R has very little or no influence on the traction exerted on the hair since the latter results mainly from friction against the friction bar 10 and the coefficient of friction with the hair of the material constituting the friction surface 13.
  • the adjustment means 20 are not necessarily made in the form of a screw system.
  • the figure 4 illustrates a variant embodiment according to which the adjustment means 20 comprise a carriage 25 that is mobile in translation parallel to the friction surface 13.
  • the carriage 25 comprises three inclined ramps 26 on which three feet 27, of the slide 11, located at opposite the friction surface 13.
  • the adjustment means 20 further comprise two resilient blades 28 interposed between the jaw 1 and the drawer 11 so as to maintain the legs 27 pressed against the inclined ramps 26.
  • the user wishes to adjust the value of the withdrawal R, it moves in translation in the direction of the arrow F2 the carriage 25 so that the ramps repel more or less the feet 27 and thus the friction bar 10 thereby adjusting the value of the withdrawal R.
  • the carriage 25 has a slider which extends outside the first jaw 1.
  • the slider 25 of the slider 25 30 is a finger 30 which engages in one or other of three complementary housing 31 of the first jaw 1.
  • the housing 31 thus define three predefined setting positions.
  • a first adjustment may for example correspond to a 0.2 mm shrinkage value R adapted for healthy hair
  • a second adjustment may correspond to a shrinkage value R of 0.5 mm adapted for fragile hair
  • the third adjustment may correspond to a withdrawal value R of 0.8 mm adapted for damaged hair.
  • the adjustment of the withdrawal R is not necessarily achieved by moving the friction bar relative to the jaw that carries it.
  • the figure 5 illustrates another embodiment in which the first smoothing plate 5 is moved, by screw adjustment means 40, in a direction parallel to a normal plane N to the working surface S 1 .
  • This displacement of the smoothing plate 5 makes it possible to adjust the value of the shrinkage R.
