  A first device 10 according to the present invention is shown in FIGS.

  The device 10 performs a particularly cosmetic treatment, applies cosmetics to the body surface and / or applies a mechanical action to the body surface, such as a massage, polishing, rubbing, shaving or tapping action, for example. It is intended to come into contact with the surface.

  Cosmetics are, for example, care or makeup products for the body surface. It is in particular in the form of a cream, emulsion, liquid and / or solid.

  Referring to FIG. 1, the device 10 is in contact with a body surface suitable for carrying a reciprocating oscillating motion relative to the support 12 and a support 12 suitable for a user to hold by hand. Member 14 and an assembly 16 for moving the contact member 14.

  Device 10 also includes a transmission mechanism 18 according to the present invention mechanically connected to contact member 14 and motion assembly 16.

  3 and 4, the device 10 also includes a tip 20 removably attached to the support 12, the tip 20 carrying a transmission mechanism 18 and a contact member 14. ing.

  Returning to FIGS. 1 and 2, the support 12 in this case comprises a hollow case 22 that houses the motion assembly 16. Case 22 defines a sleeve with axis A-A 'that is suitable for a user of device 10 to hold.

  Case 22 advantageously defines a housing 24 for insertion of tip 20 located at one end of the sleeve.

  The exercise assembly 16 is housed in the case 22. The motion assembly 16 includes a vibration motor 26 and a motion member 28 driven by the vibration motor 26 and visible in FIG.

  The movement member 28 preferably projects partly from the case 22 through the housing 24 according to a transverse axis B-B 'relative to the axis A-A'.

  The vibration motor 26 is suitable for generating a reciprocating vibration movement of the movement member 28, preferably with a vibration frequency between 100 Hz and 500 Hz.

  In this example, the motion member 28 is attached so as to vibrate relative to the support 12 about the axis B-B '. Accordingly, the motion member 28 reciprocates in the first direction S1 and the second direction S2 about the axis BB ′ over a total angular stroke of between 5 ° and 30 °, preferably between 5 ° and 15 °. Rotated.

  The movement member 28 includes a protrusion 30 for engaging with the transmission mechanism 18, which is formed by radial teeth in this example.

  Referring to FIG. 4, the contact member 14 includes a head 32 that defines a surface for contacting the user's body surface, and a member 34 for mechanically connecting to the transmission mechanism 18.

  In this example, the contact member 14 is attached so as to rotate with respect to the support 12 about the axis B-B ′. The contact member 14 reciprocates in the first direction S1 and the second direction S2 about the axis B-B '.

The moment of inertia of the contact member 14 with respect to the axis BB ′ is, for example, 500 g. exceed mm ^2, preferably from 1000g. less than mm ² .

  The contact surface is, for example, a polishing surface that can cause superficial polishing on the body surface, in particular to remove dead cells, promote uniform penetration of cosmetics into the body surface and / or the epidermis and dermis It aims at peeling for forming a fine flaw between.

  Micro-scratches will advantageously trigger a repair process to form new body tissue.

  The polished surface is obtained by a method of immersing a corindon type abrasive deposited on a plastic support covered with an epoxy resin, for example.

  This optionally makes it possible to develop a composite form of contact member 14.

  Referring to FIGS. 4 to 8, the transmission mechanism 18 according to the present invention includes a driving unit 40 intended to be attached to the motion member 28 and a driven unit 42 driven by the driving unit 40.

  The transmission mechanism 18 also comprises an assembly 44 for establishing contact between part 40 and part 42, which can be seen in FIGS.

  The drive 40 is intended to be engaged with the motion member 28 for movement according to a reciprocating oscillating movement in the first direction S1 and the second direction S2.

  Referring to FIG. 5, the drive unit 40 includes a main body 50 for assembling on the motion member 28 and a drive shaft 52 for driving the contact member 14 according to a reciprocating vibration motion.

  The assembly body 50 includes a base plate 54 having an axis B-B ′, and a plurality of tabs 55 protruding from the base plate 54 to hold the driving unit 40 in the axial direction on the tip 20.

  The base plate 54 extends so as to be orthogonal to the axis B-B ′.

  The tabs 55 protrude axially around the periphery of the base plate 54 and mutually define an insertion notch 56 for the engagement protrusion 30. Tab 55 includes a snap lock element 58 suitable for insertion under the locking surface of tip 20.

  The drive shaft 52 defines an internal hole 60 for receiving the connection member 34 having a shape that is complementary to the shape of the connection member 34.

  The connecting member 34 is thus suitable for mounting in the hole 60 to fix the contact member 14 for rotation with the drive 40.

  The drive shaft 52 protrudes axially from the base plate 54 on the opposite side of the tab 55.

  The drive shaft 52 defines on the outside a peripheral drive surface 62 for driving the driven part 42 extending around the axis B-B '.

  Referring to FIG. 6, the driven part 42 includes a base 70 and a sleeve 72 for engaging with the driving shaft 52 of the driving part 40.

  In the example shown in the drawings, the driven part 42 also comprises at least one air circulation member 74 that projects radially from the base 70 around the sleeve 72.

  The base 70 rotates about the axis B-B ′. In this example, the base 70 has a cross section that converges in the axial direction toward the sleeve 72 from its periphery to its center.

  The sleeve 72 extends in the center of the base 70 about the axis B-B ′. The sleeve 72 is engaged around the drive shaft 52.

  The sleeve 72 internally defines a peripheral driven surface 75 that is suitable for contacting the drive surface 62 using the contact assembly 44.

  In this example, the driven unit 42 includes a plurality of air circulation members 74 distributed in the angular direction about the axis B-B ′.

  Each air circulation member 74 forms a blade extending radially from the base 70 to the free end 76. This blade is preferably curved.

  In accordance with the present invention, a contact assembly 44 is inserted between the surfaces 62 and 75 to ensure contact between the peripheral drive surface 62 and the peripheral driven surface 75.

  As will be seen below, the contact assembly 44 drives the driven surface 75 while the drive surface 62 moves in the first direction S1 of rotation of the drive unit 40 about the axis BB ′. Is suitable.

  The contact assembly 44 allows the drive surface 62 to slide on the driven surface 75 while moving in the second direction S2 of rotation of the drive unit 40 about the axis BB ′. Suitable for doing.

  Advantageously, the dynamic friction coefficient CFD1 between the drive surface 62 and the driven surface 75 in the first direction S1 of rotation of the drive unit 40 is equal to the drive surface 62 and the driven surface in the second direction S2 of rotation of the drive unit 40. The coefficient of dynamic friction with the drive surface 75 is larger than CFD2.

  The dynamic friction coefficient is measured by, for example, ISO standard 8295.

  Similarly, the static friction coefficient CFS2 between the driving surface 62 and the driven surface 75 in the second direction S2 is lower than the static friction coefficient CFS1 between the driving surface 62 and the driven surface 75 in the first direction S1.

  The static friction coefficient is measured by, for example, ISO standard 8295.

  The dynamic coefficient CFD1 exceeds, for example, the static coefficient CFS2 and the dynamic coefficient CFD2. The ratio of the static coefficient CFS1 and the dynamic coefficient CFD2 exceeds, for example, 5 and particularly exceeds 10.

  As shown in FIG. 8, the contact assembly 44 advantageously includes a plurality of protrusions that selectively protrude from the drive surface 62 and / or the driven surface 75 in either the first direction S1 or the second direction S2. A member 80 is provided.

  Advantageously, the protruding member 80 selectively protrudes from the driving surface 62 in the first direction S1 and / or selectively protrudes from the driven surface 75 in the second direction S2.

  Preferably, the contact assembly 44 includes a plurality of projecting members 80 projecting from the driving surface 62 and a plurality of projecting members 80 projecting from the driven surface 75.

  The protruding member 80 is made of, for example, a fiber. They are formed, for example, by preferentially oriented bristles or fiber loops. Alternatively, the protruding member 80 is formed by flocking.

  The protruding member 80 is mounted on one and / or the other of the surfaces 62, 75, for example by surface treatment. Alternatively, the protrusions are carried by a support layer fixed on the surfaces 62, 75 that receive them.

  Thus, in one embodiment, the protruding member 80 is carried by a bay secured by adhesion on the surfaces 62, 75.

  The fibers forming the protruding member 80 are of synthetic origin, for example, or in contrast, are of natural origin, such as animal hair. Alternatively, the protruding member 80 is formed by a member that is visible to the naked eye, such as a thin piece.

  The selective orientation of the protruding member 80 ensures that the movement of the drive surface 62 in the first direction S1 causes the driven surface 75 to move in the same direction S1.

  On the contrary, the selective orientation of the protruding member 80 is such that when the drive surface 62 moves in the second direction S2, the drive surface 62 moves over the driven surface 75 without substantially driving the driven surface 75. Guarantees sliding.

  “Substantial driving” means that the driven surface 75 is less than 10% of the stroke of the driving surface 62 in the second direction S2 while the driving part 40 moves in the second direction S2, and preferably 1 Means less than%.

  Therefore, when the drive unit 40 that performs the reciprocating vibration motion moves in the first direction S1, the drive unit 40 uses the contact between the surfaces 62 and 75 and the contact assembly 44 to drive the driven unit 42. Is operated in the first direction S1.

  In contrast, when the driving unit 40 that performs reciprocating vibration motion moves in the second direction S2, the driving surface 62 slides on the driven surface 75, so that the driving unit 40 causes the driven unit 42 to move. Does not operate substantially.

  Therefore, the driven unit 42 moves in the first direction S1 when the driving unit 40 reciprocates in the first direction S1 and the second direction S2, and preferably substantially only in the first direction S1. Exercise.

  In the example shown in the drawing, the drive unit 40 that reciprocates in the first direction S1 and the second direction S2 is therefore identical using the engagement of the connecting member 34 in the drive shaft 52. The contact member 14 is operated according to the reciprocating vibration motion.

  At the same time, the drive unit 40, which performs an oscillating motion reciprocating in the first direction S1 and the second direction S2, utilizes selective contact between the surfaces 62 and 75 connected to each other by the contact assembly 44. The driven part 42 and, preferably, the air circulation member 74 it holds are actuated in the first direction S1.

  The transmission mechanism 18 is therefore particularly simple and particularly lightweight and is very effective in enhancing the function of the treatment device 10.

  The size and weight of the assembly formed by the drive unit 40, the driven unit 42 and the contact member 14 is advantageously suitable for producing a resonance effect with the frequency of changes in the movement of the drive unit 40.

  3 and 4, the tip 20 includes a base 90 for assembly within the housing 24 of the support 12, and in this example, a cap 92 secured on the base to cover the base 90. Prepare. The base 90 and the cap 92 define an inner housing 94 for accommodating the driven part 42.

  The assembly base 90 is formed by a ring removably fixed on the support 12 in the housing 24 by, for example, screwing. The assembly base 90 defines an inner surface 98 for holding the drive unit 40 in an axial position.

  The drive unit 40 rotates in the first direction S1 and the second direction S2 within the assembly base 90 about the axis BB ′ while maintaining the translational movement along the axis BB ′ by the assembly base 90. To be attached.

  A cap 92 covers the base 90. Cap 92 defines a central axial opening 98 through which contact member 14 extends. This makes the head 32 accessible from the outside so that the head 32 can contact the body surface of the user.

  The cap 92 defines a plurality of air circulation windows 100 that extend radially outward of the agitation member 74.

  A housing 94 is defined between the cap 92 and the base 90. The housing 94 is opened outward in the axial direction through the opening 98 in the axial direction, and is opened outward in the radial direction through the window 100.

  The housing 94 at least partially houses the drive unit 40 and advantageously houses the driven unit 42 with its air circulation member 74.

  The cap 92, tip 20 and air circulation member 74 thus advantageously form an air suction assembly that is capable of aspirating body surface elements separated by the contact member 14.

  The operation of the device 10 comprising the transmission mechanism 18 according to the invention will be described below.

  Initially, the tip 20 carrying the transmission mechanism 18 and the contact member 14 is reversibly mounted on the support 12 by being mounted in the housing 24.

  The drive unit 40 is engaged with the motion member 28. The engagement protrusion 30 is inserted into an insertion notch 56 defined between the tabs 55. The drive unit 40 is then capable of rotational movement with the movement member 28 about the axis B-B '.

  The connection member 34 of the contact member 14 is accommodated in the hole 60 inside the drive shaft 52. The contact member 14 can therefore rotate with the drive 40 about the axis B-B '.

  The sleeve 72 of the driven part 42 accommodates the driving shaft 52 of the driving part 40. The drive surface 62 is disposed so as to face the driven surface 75, and the contact assembly 44 is inserted between the surface 62 and the surface 75.

  When the user wishes to use the device 10, the user controls the exercise assembly 16. The motor 26 is started. The user moves the motion member 28 according to a reciprocating vibration motion about the axis B-B 'in the first direction S1 and the second direction S2.

  The motion member 28 now moves the drive 40 and the contact member 14 according to the same reciprocating vibration motion about the axis B-B 'in the first direction S1 and the second direction S2.

  The contact member 14 contacts this surface, for example, to provide a cosmetic treatment to the user's body surface, such as polishing elements on the body surface.

  Advantageously, resonance is obtained taking into account the size and weight of the movable assembly formed by the drive part 40, the driven part 42 and the contact member 14, which creates a specific tactile effect on the body surface.

  At the same time, each movement of the drive 40 in the first direction S1 is caused by the selective orientation of the projecting member 80 on the drive surface 62 and / or the driven surface 75, and in particular the driven portion 42 and advantageously. The air circulation member 74 is rotated in the same direction S1.

  Conversely, each movement of the drive unit 40 in the second direction S2 does not rotate the driven unit 42 in the same direction S2 because the drive surface 62 slides on the driven surface 75.

  The driven part 42 and the air circulation member 74 are therefore rotated about the axis B-B ', preferably only in the first direction S1.

  Inhalation occurs in the housing 98 of the cap 92, which sucks the body surface elements separated by the contact member 14.

  The function of the device 10 is therefore very simple, inexpensive and still effective, aiming to convert the reciprocating movement in the first direction S1 and the second direction S2 into a simple movement in the first direction S1. It is enhanced by using the transmission mechanism 18 according to the present invention having a simple structure.

  In the alternative shown in FIG. 9, the contact assembly 44 includes a protruding member 80 made of fiber on one of the surfaces of the drive surface 62 or the driven surface 75. The other surface has a rough surface area 102 suitable for cooperating with a protruding member 80 on the other surface.

  The rough region 102 has a roughness R of the same order of magnitude as the fiber diameter of the protruding member 80 as measured, for example, by ISO standard 12085.

  The contact assembly 44 also has a resilient surface region 104 located on the other of the drive surface 62 and the driven surface 75 that faces and contacts the protruding member 80.

  The elastic region 104 has a hardness of less than 75 Shore A, for example as measured by ISO standards ISO868 and 7619.

  The local elasticity of the elastic region 104 causes the other local deformation of the driving surface 62 and the driven surface 75 when the driving surface 62 operates the driven surface 75 in the first direction S1. . When the driving surface 62 moves in the second direction S2 with respect to the driven surface 75, the elastic deformation is relaxed, and the driving surface 62 is prevented from being driven by the driving surface 62.

  In another alternative shown in FIG. 10, the drive unit 40 translates along the axis B-B 'according to reciprocating motion in the first direction S1 and the second direction S2. It rotates the driven part 42 in the first direction S1, and does not rotate the driven part 42 in the second direction S2.

  In another alternative shown in FIG. 11, the drive unit 40 translates along axis B-B 'according to reciprocating motion in the first direction S1 and the second direction S2. This causes a translational movement of the driven part 42 in the first direction S1, and does not cause the driven part 42 to translate greatly in the second direction S2.

  In yet another alternative shown in FIG. 12, the drive unit 40 rotates about the axis B-B ′ according to a reciprocating motion in the first direction S1 and the second direction S2. It causes a translational movement of the driven part 42 in the first direction S1, and does not cause the driven part 42 to translate greatly in the second direction S2.

  In another alternative shown in FIG. 13, the drive unit 40 translates along the axis B-B ′ according to reciprocating motion in the first direction S1 and the second direction S2.

  The drive unit 40 includes a first drive surface 62 and a second drive surface 110 on the opposite side of the first drive surface 62 with respect to the axis B-B ′.

  The driven portion 42 includes a first segment 112 that faces the first driving surface 62, and a second segment 114 that faces the second driving surface 110.

  The mechanism 18 includes a first assembly 44 that establishes contact between the first drive surface 62 and a driven surface located on the first segment 112, a second drive surface 110, and a second segment. And a second assembly 116 that establishes contact with a driven surface located on 114.

  The first contact assembly 44 is suitable for driving the first driven surface located on the first segment 112 while the drive unit 40 moves in the first direction S1. Is suitable for allowing the first driven surface located on the first segment 112 to slide while moving in the second direction S2.

  Conversely, the second contact assembly 116 is suitable for driving a second driven surface located on the second segment 114 while the drive 40 moves in the second direction S2, and It is suitable to allow the second driven surface located on the second segment 114 to slide while the drive 40 moves in the first direction S1.

  Advantageously, the first segment 112 and the second segment 114 are connected at their respective ends to form a closed transport strip.

  Another alternative transmission mechanism 18 according to the present invention is shown in FIGS.

  The mechanism 18 includes a drive unit 40 that drives the first driven unit 42 and the second driven unit 120 using the first contact assembly 44 and the second contact assembly 122, respectively.

  In this example, the first driven portion 42 and the second driven portion 120 are coaxial with the axis B-B ′. The second driven part 120 extends around the first driven part 42.

  The drive unit 40 is reciprocally rotated about the axis B-B 'in the first direction S1 and the second direction S2.

  The drive unit 40 defines a first drive surface 62 of the first driven unit 42 and a second drive surface 124 of the second driven unit 120.

  In this example, the first drive surface 62 and the second drive surface 124 extend transversely to the axis B-B 'and preferably rotate about the axis B-B'. They are in this case arranged on the same lateral surface 126 of the drive 40.

  The respective driving surfaces 64 and 124 are arranged so as to face the corresponding driven surfaces 75 and 128 located on the first driven portion 42 and the second driven portion 120, respectively.

  The first contact assembly 44 is suitable for driving the first driven surface 75 located on the first driven portion 42 while the driving portion 40 moves in the first direction S1, It is suitable for allowing the first driven surface located on the first driven part 42 to slide while the driving part 40 moves in the second direction S2.

  Conversely, the second contact assembly 122 is suitable for driving the second driven surface 128 located on the second driven portion 120 while the driving portion 40 moves in the second direction S2. And suitable for allowing the second driven surface located on the second driven part 120 to slide while the driving part 40 moves in the first direction S1.

  Therefore, as shown in FIG. 15, while the drive unit 40 reciprocates, the first driven unit 42 is rotated about the axis BB ′, preferably only in the first direction S1, and the second In contrast to the first driven part 42, the driven part 120 is preferably rotated only in the second direction S2 about the axis BB ′.

  In the above example, the drive unit 40 is moved with high frequency according to the oscillating motion reciprocating in the first direction S1 and then in the second direction S2.

  Alternatively, the drive unit 40 may be moved in the first direction S1 in the first stage of use shown in FIG. 16, for example, and then in the second stage of use following the first stage, for example shown in FIG. The reciprocating motion is not necessarily repetitive or is performed at a given frequency.

  The mechanism 18 shown in FIGS. 16 and 17 utilizes the first contact assembly 44 and the second contact assembly 122, respectively, as described above, and thereby the first driven portion 42 and the second driven portion 120. The drive part 40 which drives is provided.

  In this example, the first driven part 42 and the second driven part 120 are coaxial with the axis B-B ′ and are shifted in the axial direction along the axis B-B ′.
