However, the presence of joints is generally preferred in ergonomics in which the joints are provided.

The jaws 3, 4 define areas with each other for the treatment of the hair, the areas being intended to receive a second piece of hair to be treated, and the hand piece 2 has a hair end during the treatment, for example from the hair root. Is moved along the hair of the tuft in the direction of.

In this embodiment, the hand piece 2 combs the hair by passing the hair through the comb 13, applies the beauty products, treats the hair with steam and then in this case applies to the two heated plates. It is configured to carry out the heat treatment of the hair by contact with the two heating surfaces 15, 16 formed by it.

The direction of movement (D) of the handpiece (2) for the hair-illustrated in Figure 2 is substantially the longitudinal axis (X ₂₎ of longitudinal axis (X ₁₎ and lower arms (6) of the upper arm (5) It is preferred to be vertical.

In that embodiment, the hand piece 2 is connected by a line 18 to a base station (not shown) which is fixed during the process and connected to the mains.

Such a base station can perform additional functions to provide a power supply to the hand piece 2, also to provide a water supply to generate steam, and also to process electrical signals received from the hand piece 2. . Thus, the line 18 connecting the hand piece 2 to the base station can comprise various electrical conductors and a water supply pipe.

A user interface (not shown in the figures) may be present on the hand piece 2, for example, to allow the user to start or not to specific components thereof.

The cosmetics are applied by the refill product 20 carried by the arm 5 or 6 of one of the two arms, in this case the upper arm 5. The refill product 20 is brought into contact with the pressurizing element 21 disposed opposite the refill product 20.

The refill product 20 comprises an application member 26 having a body 23 and an application surface 35 held in the body 23 and in contact with the hair present on the pressing element 21.

The refill product 20 is fastened to the arm 5 or 6 by any means as illustrated in FIG. 3, in particular by sliding the rib 27 of the body 23 into a groove 29 having a complementary shape. Can be.

The body 23 has a cavity 30 that opens outwards through an opening 31 into which the applicator member 26 is inserted while the refill product 20 is being manufactured. Body 23 includes reliefs 32 for holding applicator member 26 extending into cavity 30.

The body 23 and the applicator member 26 have substantially the entire shape of a cuboid and are elongate along the longitudinal axis Z.

The applicator member 26 consists of fibers assembled and oriented in substantially the same direction parallel to the axis Z, for example, to form a felt. The application surface 35 of the applicator member 26 may be flat as illustrated.

Alternatively, applicator member 26 can be manufactured by assembling two felts, in particular having different densities. According to this alternative, one of the felts may consist of fibers oriented in one direction, in particular parallel to the axis Z, and the other of the felts is perpendicular to the other fibers, in particular the axis Z It can be composed of fibers oriented in a direction perpendicular to the).

As can be noted, in FIG. 3, the pressing element 21 has a support surface 36 which can have a shape complementary to the application surface 35. Thus, the support surface 36 can be flat, elongate, and applied along the longitudinal axis Y substantially parallel to the longitudinal axis Z at the position in which the arms 5, 6 are moved together. It may have substantially the same degree as the surface 35.

The pressing element 21 is removably received in the housing 38 through the front opening in the housing. The housing 38 is also opened outward through at least one opening 37 facing the applicator member 26.

In the embodiment illustrated in FIG. 3, the pressing element 21 is introduced into the housing 38 by sliding the ribs 45 on the housing 38 into the corresponding grooves 48 of the pressing element 21. Ribs 45 are disposed on opposite sidewalls 54, 56 of housing 38. The grooves 48 of the pressing element 21 are arranged in the side walls of the pressing element 21, which face the walls 54, 56, respectively.

The pressing element 21 can move along an axis Q perpendicular to the longitudinal axis Y between the low positions moved with the high position spaced apart from the bottom of the housing 38.

The pressurizing element 21 is supported by a support means 40 extending in the housing 38 to cause the pressurizing element 21 to perform a rocking motion and in the open position of the arms 5, 6. 21) to a high position.

The range of movement P between the high and low positions of the pressing element is between 1 mm and 5 mm, for example equal to about 3 mm. The movement of the pressing element 21 is limited by the width l of the bottom 44 or groove 48 of the housing.

The range of movement of the pressing element advantageously allows the hairs to be substantially aligned, that is to say without the deviation of one hair between the portion located between the heated plates and the portion located between the pressing element and the applicator member. It is possible to position the pressing element in the closed position. That is, while the device is in use, the distance between the two heated plates is substantially equal to the distance between the pressing element and the applicator member, and these two distances are measured in a direction that is substantially collinear with the axis Q. do. In addition, the support surface 36 of the pressing element is substantially coplanar with the heating surface 16, while the application surface 35 is substantially with the heating surface 15 in planes perpendicular to the axis Q. Are on the same plane. Thus, this improves the straightening of the hair by the device.

In the embodiment illustrated in FIGS. 3, 5 and 6, the support means 40 is plate spring fastened to the depression 41 of the pressing element 21 oriented towards the bottom 42 of the housing 38. to be. Thus, the leaf spring 40 has the bottom of the housing 38 in the region 43 in which the oscillation of the pressing element 21 occurs about the axis of rotation B which is substantially perpendicular to the axes Y, Q. 42).

At the ends, the leaf spring 40 has fastening tabs 44 brought into contact with the pressing element 21 at the depression 41, between which the convex portion (convex toward the bottom 42 of the housing 38) ( 46), the central portion of the convex portion defines the swing region 43.

The height s taken by the leaf spring 40 before being introduced into the housing 38 is greater than or equal to the distance f between the bottom of the housing 38 and the bottom of the recess 41. Thus, the leaf spring 40 is always loaded by contact with the bottom of the housing 44. The distance f is for example between 1 mm and 5 mm, for example equal to about 3 mm.

The housing 38 is of substantially the same length L as the pressing element 21. The length L of the pressing element 21 is for example between 70 mm and 110 mm, preferably 90 mm.

The grooves 48 have a width l greater than the thickness e of the ribs 45. The width l of the ribs 45 is for example between 1 mm and 5 mm, for example about 3.2 mm. The thickness e of the grooves 48 is equal to between 0.5 mm and 5 mm, in this case 1 mm. This difference allows the pressing element 21 to move and / or swing along the axis Y as described above.

In the embodiment illustrated in FIG. 3, the two ribs 45 are offset along the axis Q by a distance d, for example between 1 mm and 5 mm, for example about 2 mm.

The pressurizing element 21 is present in the groove 48 of the pressurizing element 21 and in FIGS. 5 and 6 engaged with the set back relief 52 which can be seen in FIG. 4 in the rib 45 of the housing 38. It is locked in the housing 38 by a visible projecting relief 50.

Since the protruding relief 50 does not extend along the entire width l of the groove 48, in order to remove the pressing element 21, the protruding relief 50 is pressed along the axis Q and the set back relief 52 is removed. It is sufficient to pressurize the urging element so as to separate it. Thus, the pressing element 21 can slide forward in the housing 38.

The comb 13 is located upstream of the applicator member 26 and the pressing element 21 in the direction of movement D of the hand piece 2. The comb 13 is integral with the pressing element 21 and in particular is molded integrally with the pressing element.

The comb 13 extends substantially along the entire length of the support surface parallel to the support surface 36.

The comb 13 has a plurality of teeth 55, each of which extends along an axis parallel to the axis Q. The comb 13 advantageously has at least 20 teeth 55, more preferably at least 30 teeth 55, in which case there are about 44 teeth.

The base of the teeth 55 is set rearward with respect to the support surface 35, in particular by a distance r between 0.2 mm and 5 mm, for example equal to 2 mm. This allows the hair to be properly inserted between the support surface 36 and the application surface 35.

The teeth 55 are preferably all the same height H, which is between 2 mm and 12 mm, for example equal to 8 mm. This height is large enough to adequately keep the hair between the teeth 55.

The teeth 55 are all at the same distance from each other. The spacing k between the teeth 55 is preferably equal to between 0.3 mm and 3 mm, for example 1 mm.
