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 apparatus comprising at least: two jaws, first and second, elongated and hinged together to be movable between an open position and a closed position in which they define, by facing working surfaces, a hair treatment zone; electric heating means associated with at least one of the work surfaces,
- the first jaw at least comprises:
- At least one friction bar having a friction surface which defines a plane parallel to the adjacent working surface, which protrudes from the adjacent working surface and which is adapted to cooperate with an element of the second jaw so as to define, in the closed position of the jaws on a lock of hair, a traction zone generating during movement of the apparatus on the lock of hair a traction force additional to the traction force generated by the treatment zone means for adjusting the so-called withdrawal distance between the plane of the friction surface and the working surface and measured perpendicularly to the working surface.
- the friction bar can for example be designed so that in the closed position of the jaws, the traction zone has a coefficient of friction higher than the coefficient of friction of the zone. treatment.
- 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 hair part located between the scalp and the traction zone and therefore especially that located in the treatment zone, so that the heating of the hair in traction in the treatment zone provides an optimal smoothing and very significantly greater than that which would result 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 still 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 withdrawal distance adjusting means are adapted to allow a variation of the value of the withdrawal distance between 0.1 mm and 5 mm.
- the withdrawal distance adjustment means are adapted to present at least three predefined settings:
- 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 withdrawal distance adjustment means are:
- the surface of work adjacent to the friction bar is formed by a smoothing plate and the means for adjusting the withdrawal distance are:
- the friction bar is rigidly connected to the first jaw so as to have a fixed position relative thereto.
- the element of the second jaw for cooperating 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 component of 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 with regard to 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.

- Each working surface Si and S 2 has, according to the example shown, a generally rectangular shape and is made of a thermally conductive material having a surface condition adapted to be placed in contact with hair without the risk of damaging them.
- each working surface Si, S 2 could for example be smooth by being polished or possibly covered with an enamel, a ceramic material, a low friction coefficient polymer material or a low coefficient enamel friction or a layer of glass.
- the working surfaces Si 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 smoothing plate 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 Si, 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 S2.
- 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 1 1 movable in translation parallel to a normal plane N to the working surface Si.
- the carriage 1 1 comprises opposite the first jaw 1 a silicone head 12 which is overmolded on the carriage 1 1 and which defines a substantially flat surface friction 13.
- the friction bar 10 occupies any the width of the space between the left edge of the first smoothing plate 5 and the corresponding edge of the first jaw 1.
- the friction bar 10 is furthermore made in such a way that the friction surface 13 protrudes from the working surface Si of the first plate 5.
- the working surface Si is therefore set back with respect to the friction surface 13.
- the value of the shrinkage R measured between the plane of the Si working surface 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 1 1 and the first jaw 1.
- the means of Adjustment 20 comprise a screw system which makes it possible to continuously adjust the value of the shrinkage 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.

- a user wishes to smooth a strand of hair M, it closes the device A on said wick, as shown in Figure 3.
- the user will then be careful to place the friction bar 10 to the opposite of the scalp C relative to the first smoothing plate 5.
- the first 5 and second 6 smoothing plates define a treatment zone T which has a generally rectangular cross section in cross section.
- 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 Si 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 region 16 is greater than that of the zone
- This difference in friction is all the more accentuated as 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 adjustment 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 closure of the apparatus of the invention. Hairstyle on the lock M of hair to be treated.

- 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 setting 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, if any, influence on the traction exerted on the hair since the latter results mainly from the 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.
- FIG. 4 illustrates an embodiment variant 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 drawer 1 1, located opposite the friction surface 13.
- the adjustment means 20 further comprise two resilient blades 28 interposed between the jaw 1 and the drawer 1 1 so as to maintain the feet 27 pressed against the inclined ramps 26
- the user wishes to adjust the value of the withdrawal R, he moves in translation in the direction of the arrow F2 the carriage 25 so that the ramps repel more or less feet 27 and thus the friction bar 10 thus allowing adjust the value of the withdrawal R.
- the carriage 25 has a slider which extends outside the first jaw 1.
- the cursor of the carriage 25 has a finger 30 which engages in one or the other of three complementary housing 31 of the first jaw 1.
- the slots 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.
- FIG. 5 illustrates another embodiment according to 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 Si.
- the smoothing plate 5 makes it possible to adjust the value of the shrinkage R.
- the friction bar 10 is rigidly connected to the first jaw 1 and the second jaw 2 comprises a friction bar 41 located in The friction bar 41 is also rigidly connected to the second jaw 2.
