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 exerting a significant pressure force to keep the jaws closed and apply sufficient pressure on the lock of hair to be treated.
  • the best results are obtained when the hair of the wick to be treated is distributed as evenly as possible over the entire length of the working surfaces of the jaws and when the working surfaces enclosing the hair are substantially parallel.
  • a patent application EP 1 030 571 proposed a floating mounting of the work surfaces by means of springs interposed between each work surface and the jaw which carries it.
  • a pivot connection is a mechanical connection which has a single degree of freedom in rotation about an axis and optionally a degree of freedom in translation along this axis.
  • the pivot connection within the meaning of the invention, has a degree of freedom in rotation and a degree in translation it can also be called sliding pivot in accordance with the standard designation.
  • a pivot connection in the sense of the invention therefore has a maximum of two degrees of freedom, one in rotation and one in translation, and, preferably, the pivot connection according to the invention will have a single degree of freedom in rotation and no degree of freedom in translation.
  • the combination of the two cross pivot links according to the invention will have no degree of freedom in translation or rotation in a direction normal to the corresponding working surface.
  • the movements authorized by the hinge means according to the invention do not implement an elastic deformation of the constituent elements of the cross pivot links which allows a good transmission of clamping forces to the working surfaces thus ensuring a good smoothing of the hair.
  • the intersection of the axes of the two pivot links of the first articulation means is preferably, but not necessarily, situated substantially in line with the isobarycenter of the corresponding work surface.
  • Such an embodiment makes it possible to optimize the implementation of the two crossed pivot links and to produce the latter at a lower cost.
  • the working surface of the first jaw is formed by a smoothing plate which is carried by a cradle comprising connecting bearings with one of the branches of the spider.
  • a smoothing plate which is carried by a cradle comprising connecting bearings with one of the branches of the spider.
  • the working head can be connected to the body by the cross.
  • either a single work surface is associated with two cross pivot links or the two work surfaces are each associated with two cross pivot links.
  • the second jaw also comprises between the hinge and the corresponding working surface of the second articulation means which comprise at least a first pivot connection axis A parallel to the longitudinal axis L 'and at least one second pivot connection axis ⁇ perpendicular to the axis L'.
  • the hair treatment area defined between the two working surfaces produces a working volume whose two surfaces can remain all the more parallel as they are mounted on a pivot each.
  • the intersection of the axes of the two pivot links of the second articulation means is preferably situated substantially perpendicular to the isobarycenter. of the corresponding work surface.
  • the working surface of the second jaw is formed by a smoothing plate which is carried by a cradle comprising connecting bearings with one of the branches of the spider.
  • the working head is connected to the body by the spider.
  • the axes of the pivot links forming the hinge means are not coplanar.
  • a hairdressing apparatus as illustrated in FIG. figure 1 and designated as a whole by the reference A, comprises two elongate jaws 1 and 2 of generally parallelepipedal shape and each extending along a longitudinal axis L, L '.
  • 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 FIG. figure 1 , and a closed position.
  • 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 facing each other and extend over only a portion of the length of the jaws 1 and 2, so as to define in the closed position a hair treatment area .
  • 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, a paint or an enamel with a low coefficient of friction or a layer of glass.
  • Work surfaces S 1 and S 2 are for example formed by smoothing plates respectively the first 5 and second 6.
  • the straightening plates 5 and 6 are each associated with electrical heating means 7 into contact with the rear surface of the corresponding plate, located opposite the working surface S 1 , S 2 , as shown by Figures 2 and 3 for the first smoothing plate 5.
  • the electric heating means can be made in any appropriate manner such as for example in the form of a resistive heating element CTP or infrared emission.
  • the electric heating means 7 are therefore located inside the first 1 and second 2 jaws.
  • the heating means are for example designed to maintain a predetermined target temperature automatically.
  • the heating means could also be connected to unrepresented control means 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 invention proposes to implement between the hinge 4 and the first working surface S 1 hinge means 10 which comprise a first pivot connection 11 of axis ⁇ parallel to the L-axis and a second pivot link 12 axis ⁇ perpendicular to the axis L.
  • the combination of the two pivot links 11 and 12 allows the first working surface S 1 to have two degrees of freedom in rotation relative to the first jaw 1 and more particularly to the body 13 of the latter.
  • the first work surface S 1 can be placed parallel to the second work surface S 1 when the hairdressing appliance is closed on a wick to smooth.
  • the smoothing plate 5 is carried by a cradle 15 and the hinge means 10 are interposed between the cradle 15 and the body 13 of the first jaw 1.
  • the hinge means 10 then comprise a spider 16 which comprises two branches perpendicular 17 and 18 respectively defining the axis of rotation ⁇ and the axis of rotation ⁇ .
  • the two branches 17 and 18 have a cylindrical shape of revolution and are rigidly connected substantially in their middle.
  • the body 13 of the first jaw comprises two bearings 20 which cooperate with the first branch 17 and are located on either side of the second branch 18.
  • the two bearings 20 have in this case a C shape.
  • the bearings 20 are, for example, made of plastics material and shaped so as to allow a force-engaging fit, in a direction normal to the working surface S 1 , on the first branch 17.
  • the bearings 20 and the first branch 17 therefore form the first pivot connection 11 allowing a rotation of the cradle 15 parallel to the longitudinal axis L of the first jaw.
  • the cradle 15 also comprises two bearings 21 which cooperate with the second branch 18 and are located on either side of the first branch 17. Like the bearings 20, the two bearings 21 have a C shape and are made of plastic . The bearings 21 are shaped so as to allow mounting on the second branch 17 by force engagement, in a direction normal to the working surface S 1 . The bearings 21 and the second branch 18 form the second pivot connection 12 allowing a rotation of the cradle 15 transversely to the longitudinal axis L of the first jaw 1.
  • the C shape open towards the cradle 15 for the bearings 20 and open towards the body 13 for the bearings 21 and the implementation of the spider 16 allow a simple and reliable mounting of the articulation means 10.
  • the axis ⁇ materialized by the branch 17 is substantially centered with respect to the width of the working surface S 1 defined by the plate 5.
  • the axis ⁇ materialized by the branch 18 is substantially centered with respect to the length of the working surface S 1 defined by the plate 5.
  • the intersection of the axes ⁇ and ⁇ , the center of the cross 16 is substantially located vertically above the isobarycentre G of the working surface S 1 defined by the plate 5.
  • the axes of the branches 17 and 18 of the spider 16 are substantially coplanar.
  • the figure 4 shows an alternative embodiment according to which the axes ⁇ and ⁇ , branches 17 and 18, are not coplanar and are offset relative to each other in a direction perpendicular to the two axes ⁇ and ⁇ .
  • This configuration allows, according to the illustrated example, to increase the distance between the cradle 15 and the body 13 so as to increase the amplitude of rotation of the cradle 15 along the two axes ⁇ and ⁇ .
  • first smoothing plate 5 is associated with the hinge means 10 with crossed pivot links.
  • pivot pivot linkage means in association with the second smoothing plate 6 as illustrated in FIG. figure 5 .
  • second articulation means 10 'with crossed pivot connections will preferably be made as the first articulation means 10 so that it is not necessary to describe them here further.
  • the articulation means 10 are not necessarily interposed between a cradle directly carrying a smoothing plate and the body of the first jaw.
  • the figure 6 illustrates another embodiment in which the first jaw 1 comprises an elongated body which is hinged by the hinge 4 on the second jaw 2.
  • the first jaw 1 further comprises opposite the hinge 4 a working head 25 Elongated axis L extending in the extension of the body 13.
  • the working head 25 then carries the first smoothing plate 5 which defines the first working surface S 1 .
  • the working head 25 may also comprise the heating means associated with the first smoothing plate 5.
  • the articulation means 10 are then interposed between the working head 25 and the body 13 so that is the assembly of the working head 25 which is movable along two axes of rotation perpendicular to the body 13.
  • the hinge means 10 comprise a spider 26, a first branch 27 defines the axis of rotation ⁇ and a second branch 28 which defines the axis of rotation ⁇ .
  • the first branch 27 has a length greater than the length of the second branch 28.
  • the body 13 has a bearing 29 which cooperates with the first branch 27 so as to define the pivot connection axis L.
  • the first branch 27 is substantially centered relative to the width of the working surface S 1 defined by the plate 5.
  • the first branch 27 extends beyond the body 13 to the inside of the working head 25.
  • the first branch 27 carries the second branch 28 which is located inside the working head 25.
  • the second branch 28 is articulated on the working head 25 by two bearings 30, only one being visible at the figure 5 .
  • the bearings 30 are located on either side of the first branch 27.
  • the bearings 30 and the second branch 28 together define the pivot link axis ⁇ perpendicular to the axis A.
  • the second branch 28 is substantially centered with respect to the length of the working surface S 1 defined by the plate 5.
  • the intersection of the branches 27 and 28 is substantially located in line with the isobarycentre G of the working surface S 1 defined by the plate 5.
  • the spider 26 could have a T shape.
  • the spider 26 has a shape close to that of a Lorraine cross.
  • the first branch 27 extends inside the head 25 beyond the second branch 28 so as to define a stop which, on the one hand, limits the amplitude of rotation of the head 25 around the second branch 28 and, on the other hand, cooperates with ribs 31 of the working head 25 to block the translation of the working head 25 along the second leg 28.
  • the spider 26 comprises, at inside the body 13, an auxiliary branch 32 which is parallel to the second branch 28 and which extends on either side of the first branch 27.
  • the auxiliary branch 32 abuts against a rib 33 of the body 13 to blocking the translation of the head 25 along the first branch 27.
  • the auxiliary branch 32 also contributes to limiting the amplitude of the rotation of the head 25 around the axis of rotation ⁇ defined by the first branch 27.
  • the first jaw 1 comprises a working head 25.
  • the second jaw 2 may also comprise a working head 35 connected to the body 36 of the second jaw 2 by the second articulation means 10 '.
  • These second hinge means 10 ' are then made as the first hinge means 10 between the body 13 of the first jaw 1 and its working head 25. It is therefore not necessary to further describe the working head of the second jaw and its associated means of articulation.
