• the forces exerted by the skin against at least the second roller 5 are less than the forces respectively exerted by the return member 14, the latter returns the second roller 5 to its first position, which thus brings the first and second rollers 4, 5, until reaching a position of equilibrium.
• Obtaining such a balance advantageously makes it possible to control and limit the forces exerted by the massage head 1 on the skin (and in particular the forces of wrinkling the skin in the case of operation according to the "palpation" technique.
• the implementation of the return member 14 makes it possible to choose by design, the maximum admissible force within the work zone, that is to say between the first and second rollers 4, 5, and therefore of do not leave the assessment of this effort (which results in particular from the pressure applied to the skin) to the user of the massage 1, as could be the case with the massage heads of the prior art.
• This thus considerably reinforces the safety and the simplicity of use of the massage head 1 and of the apparatus 2 which are the subject of the invention, in particular allowing their use by an unqualified user (that is to say not having specific knowledge in the field of massage).
• the return member 14 may be of any suitable known type, and may for example comprise one or more helical tension or compression springs ("coil” springs), one or more torsion coil springs, one or more several leaf springs, or even a combination of these.
• the return member 14 comprises a single helical torsion spring 15, one of the legs of which is positioned resting against a surface of the frame. 3 and the other of the legs is positioned resting against a surface of the second support means 12 of the second roller 5, and the turns of which are wound around the third shaft which connects the second support means 12 to the frame 3.
• other arrangements and configurations of the return member 14 may be used, without departing from the scope of the invention, to obtain the desired return effect.
• the tare of the return member 14, and in particular its return force is chosen, depending on the targeted application and the skin area to be treated, depending on the resistance threshold of the skin.
• the second roller 5 approaches the first roller 4 under the effect of the return member 14.
• the return force of the return member 14 is on the contrary less than the resistance force of the skin, so that the second roller 5 tends to move away from the first roller 4, its second axis d 'extension B-B' moving to its second position. This improves both the efficiency and the comfort of massaging the skin by the massage head 1, while ensuring the safety of use of the massage head 1 by an unqualified user.
• the return member 14 is calibrated so that it exerts a return force of the second axis B-B ', from its second position to its first position, which is between 2 N and 20 N, and more preferably between 4 N and 10 N.
• the torque of this helical spring 15 of torsion may advantageously be between 10 Nmm and 50 Nmm, more advantageously still between 20 and 40 Nmm.
• Such a calibration is in fact particularly well suited for the treatment, using the massage head 1, of a zone of skin of the face according to the technique known as “palpating” mentioned above.
• the first and second positions of the second axis BB 'of extension and rotation of the second roller 5 are stop positions, so as to mechanically limit, reliably and repeatably, the spacing range relative to the first and second rollers 4, 5.
• said first and second positions are defined by fixed mechanical stops, defined once and for all during the design of the massage head 1. No particular adjustment is thus required on the part of the user.
• the second position of the second axis BB 'of the second roller 5 is defined by two fixed lateral stops 16A, 16B arranged at the level of the second support means 12 ( Figures 1 and 2) , and which bear against an external surface of the housing 3, formed by the frame 3 of the massage head 1, when the second axis BB 'occupies its second position ( Figures 5 and 6).
• a single fixed stop could be considered.
• the stops 16A, 16B are designed and dimensioned to maintain the surface of the second roller 5 at a distance from the frame 3, so as to avoid any contact between the latter.
• the first position of the second axis BB 'of the second roller 5 can for its part be defined, for example, by at least one fixed stop (and preferably two, not visible in the figures) arranged at the level of the second support means 12, and which bears against a surface of the first support means 11 of the first roller 4 when the second axis BB 'occupies its first position.
• this fixed stop furthermore makes it possible to avoid advantageously any interaction between the second support means 12 and the drive system housed within the housing 3.
• said first and second positions could on the contrary be one and / or the other defined by adjustable mechanical stops (for example, screw), so that the user can define and adjust himself the value of the minimum E min and maximum E max spacing desired.
• the frame or housing 3 can advantageously extend along a fourth axis (or fourth direction) D-D ’between
• the massage head 1 can then be advantageously designed and configured so as to define a plane Pi of contact of the first and second rollers 4, 5 with the skin which is oriented secant and not orthogonal to said fourth axis DD 'of extension of the frame 3 of the massage head 1, and this, more preferably, regardless of the (first or second) position occupied by the second axis BB' of extension and rotation of the second roller 5.
• this plane Pi of contact of the first and second rollers 4, 5 with the skin is secant and not orthogonal to the fourth axis DD 'at a minimum contact angle a min of at least 15 °, when the second axis BB 'occupies its first position, and according to a maximum contact angle O max of 110 ° at most when the second axis B-B' respectively occupies its second position.
• Such an inclination of the plane Pi of contact of the rollers 4, 5 with the skin contributes to excellent ergonomics of the head and of the massager 1, facilitating their grip and their use regardless of the skin area to be treated. .
• the angle of minimum contact a min may advantageously be chosen equal to 72.5 °, while the maximum contact angle a max may be advantageously chosen equal to 91.5 °.
• the third axis CC 'of pivoting of the second support means 12 of the second roller 5 relative to the frame 3 of the massage head 1 may be included in a plane containing the fourth axis DD 'of extension of said frame 3, which contributes to the simplicity of design and the compactness of the massage head 1.
• the system for adjusting the relative position of the first and second rollers 4, 5 may advantageously be designed and configured so as to define between, on the one hand a plane P2 comprising the first axis AA 'and the third axis CC' and, on the other hand a plane P3 comprising the second axis BB 'and the third axis C-C ', a minimum opening angle p min comprised between 95 ° and 110 ° (and preferably equal to 105 °) when said second axis BB' occupies its first position, and a maximum opening angle pmax between 135 ° and 150 ° (and preferably equal to 143 °) when said second axis B-B 'respectively occupies said second position.
