The present invention relates to a massage device intended to be applied to the skin and equipped, on one of its faces, with at least two elements each mounted freely rotatable around an associated axis, each rotary element having the overall shape of a solid of revolution around its associated axis, each axis being linked to a support, the directions of the two axes forming between them a beta obliquity angle of between 60 ° and 170 °, the rotary elements being of a flexible material , in particular elastomer or thermoplastic elastomer,
  • the support comprising, for a massage device with two rotary elements, a stop means capable of being supported by at least one contact point on a reference plane when this plane also contacts each of the rotary elements,
  • a plane parallel to the axes of the two rotary elements being inclined by an angle alpha, on the reference plane, when the device is pressed on this reference plane.

On connait déjà, dans l'état de la technique, un appareil de massage de ce type, notamment d'après US-A-1 999 939. L'effet de massage produit demande à être amélioré.There is already known, in the prior art, a massage device of this type, in particular from US-A-1 999 939. The massage effect produced needs to be improved.

On connaît également, d'après DE-C-841 207, un appareil de massage dans lequel les éléments rotatifs, en un matériau souple, présentent des reliefs qui contribuent à un bon effet de massage.DE-C-841 207 also discloses a massage device in which the rotary elements, made of a flexible material, have reliefs which contribute to a good massage effect.

Il est souhaitable, cependant, d'améliorer encore cet effet de massage pour obtenir une meilleure tonicité de la peau et une diminution significative de l'eau et de la graisse en surface de la peau, après massage.It is desirable, however, to further improve this massage effect in order to obtain a better tone of the skin and a significant reduction in the water and fat on the surface of the skin, after massage.

On souhaite, notamment, que l'appareil de massage assure une action efficace de plissé-roulé sur la peau, pour un déplacement dans un sens, et une action de relâchement de la peau par un déplacement en sens opposé.In particular, we would like the massage device to provide an effective pleated-rolled action on the skin, for a displacement in one direction, and an action of relaxation of the skin by a displacement in the opposite direction.

Il est souhaitable en outre que l'appareil de massage reste d'une fabrication simple et économique, et d'un emploi facile.It is further desirable that the massage device remains simple and economical to manufacture, and easy to use.

Selon l'invention, un appareil de massage du genre défini précédemment, est caractérisé par le fait que :
   l'angle alpha d'inclinaison est compris entre 3° et 20° et que les éléments rotatifs présentent des reliefs dont les extrémités de contact, destinées à s'appliquer sur la peau, sont espacées suivant la direction axiale et la direction périphérique de l'élément rotatif.According to the invention, a massage device of the kind defined above, is characterized in that:
the angle of inclination alpha is between 3 ° and 20 ° and that the rotary elements have reliefs whose contact ends, intended to be applied to the skin, are spaced apart in the axial direction and the peripheral direction of the 'rotating element.

On obtient lors du massage un mouvement oscillatoire transversal ainsi qu'un mouvement oscillatoire vertical. Le dispositif de massage apporte un effet de drainage progressif de la peau mais de façon interrompue et avec des vibrations.A transverse oscillatory movement is obtained during the massage as well as a vertical oscillatory movement. The massage device brings a progressive drainage effect of the skin but in an interrupted manner and with vibrations.

L'angle d'inclinaison alpha est avantageusement compris entre 5° et 7°.The angle of inclination alpha is advantageously between 5 ° and 7 °.

Le moyen de butée peut être constitué par une saillie de la face du support destinée à être mise en regard de la peau.The abutment means can be constituted by a projection of the face of the support intended to be placed opposite the skin.

De préférence, les extrémités de contact de deux reliefs successifs suivant la direction axiale sont décalées suivant la direction périphérique.Preferably, the contact ends of two successive reliefs in the axial direction are offset in the peripheral direction.

Le susdit angle béta est avantageusement compris entre 115° et 125°. Dans le cas où l'appareil de massage comporte plusieurs groupes de deux éléments rotatifs, chaque angle béta a sensiblement la même valeur.The above beta angle is advantageously between 115 ° and 125 °. In the case where the massage device comprises several groups of two rotary elements, each beta angle has substantially the same value.

Les axes des deux éléments rotatifs d'un même groupe peuvent être coplanaires et situés dans le plan S, leur prolongement se coupant en un point d'intersection situé du même côté du plan d'appui P que les éléments rotatifs.The axes of the two rotary elements of the same group can be coplanar and located in the plane S, their extension intersecting at a point of intersection located on the same side of the support plane P as the rotary elements.

Chaque élément rotatif a une dimension longitudinale selon la direction de son axe respectif au moins égale à sa plus grande dimension transversale.Each rotary element has a longitudinal dimension in the direction of its respective axis at least equal to its largest transverse dimension.

Lorsque les éléments rotatifs sont disposés en au moins une double rangée d'éléments, ces éléments rotatifs peuvent être disposés en quinconce.When the rotary elements are arranged in at least a double row of elements, these rotary elements can be staggered.

Selon une autre possibilité, avec des éléments rotatifs disposés en au moins une double rangée, les axes des éléments associés étant coplanaires, les plans d'une même double rangée d'éléments rotatifs sont tous parallèles entre eux.According to another possibility, with rotary elements arranged in at least one double row, the axes of the associated elements being coplanar, the planes of the same double row of rotary elements are all parallel to each other.

Les plans d'une même double rangée peuvent se subdiviser en un premier et un second groupes, en particulier égaux, tous les plans d'un même groupe étant parallèles entre eux, deux plans, chacun d'un groupe différent, étant symétriques l'un de l'autre par rapport à un plan orthogonal au plan P de référence.The planes of the same double row can be subdivided into a first and a second group, in particular equal, all the planes of the same group being parallel to each other, two planes, each of a different group, being symmetrical l ' one of the other with respect to a plane orthogonal to the plane P of reference.

Les plans S des deux groupes peuvent être disposés de façon à ce qu'un plan S du premier groupe suive un plan S du second groupe en alternance.The S planes of the two groups can be arranged so that an S plane of the first group follows an S plane of the second group alternately.

Les points d'intersection des axes de quatre éléments voisins dont deux dans une rangée, les deux autres dans l'autre rangée, peuvent être confondus en un seul point d'intersection.The points of intersection of the axes of four neighboring elements, two of which in a row, the other two in the other row, can be merged into a single point of intersection.

Un moyen de réglage de l'angle d'obliquité béta des axes des éléments rotatifs peut être prévu.Means for adjusting the beta obliquity angle of the axes of the rotary elements can be provided.

Il est à noter que les éléments rotatifs, de forme allongée, ont des extrémités opposées à celles voisines de la peau qui forment une ouverture de sortie nettement plus étroite que l'ouverture d'entrée. L'ouverture de sortie peut être comprise entre 1 mm et 50 mm, et un dispositif pour faire varier l'ouverture de sortie peut être prévu. Deux éléments rotatifs coopérant ensemble forment ainsi une sorte de goulet d'étranglement pour la peau comprise entre eux.It should be noted that the rotary elements, of elongated shape, have ends opposite those close to the skin which form an outlet opening which is significantly narrower than the inlet opening. The outlet opening can be between 1 mm and 50 mm, and a device for varying the opening output can be expected. Two rotating elements cooperating together thus form a sort of bottleneck for the skin between them.

L'invention consiste, mises à part les dispositions exposées ci-dessus, en un certain nombre d'autres dispositions dont il sera plus explicitement question ci-après dans la description d'exemples de réalisation décrits avec référence aux dessins ci-annexés, mais qui ne sont nullement limitatifs.The invention consists, apart from the arrangements set out above, of a certain number of other arrangements which will be more explicitly discussed below in the description of exemplary embodiments described with reference to the attached drawings, but which are in no way limiting.

   La figure 1 montre un schéma de principe de l'appareil de massage de la peau selon la présente invention ; le support de l'appareil n'a pas été présenté à l'exception du moyen d'appui apparaissant sous le chiffre de référence 1. L'appareil comporte deux éléments rotatifs se présentant sous la forme d'un premier rouleau 2 et d'un second rouleau 3.

Figure 1 shows a block diagram of the skin massager according to the present invention; the support of the device has not been presented with the exception of the support means appearing under the reference numeral 1. The device has two rotary elements in the form of a first roller 2 and a second roller 3. The rollers 2 and 3 are identical and each has the overall shape of a straight cylinder of revolution about a corresponding axis. The roller 2 has an axis referenced by 4 while the roller 3 has an axis referenced by 5. The axes 4 and 5 are fixed to the support of the device not shown. Thanks to these axes supported by the support, each roller 2 and 3 is freely rotatable around its associated axis. The axes 4 and 5 are generally coplanar and their virtual extensions intersect at a point of intersection referenced by the number 10. The axes 4 and 5 determine a plane S in which they form a beta obliquity angle. This beta angle is between 60 and 170 °. The axes 4 and 5 may not be coplanar, as in the case of FIG. 14, (rotary elements arranged in staggered rows) in which case the beta angle is that formed by directions parallel to the above axes, located in the same plane.

Un plan de référence P entre en contact en un point 11 avec le moyen de butée 1, en un point 12 avec le rouleau 2 et en un point 13 avec le rouleau 3. On notera que les points 12 et 13 sont chacun situés sur l'extrémité circulaire de chaque rouleau 2, 3, la plus éloignée du point 10 d'intersection du prolongement des axes 4 et 5. Le plan P forme un angle dièdre alpha avec le plan S qui contient les deux axes 4 et 5, ces deux axes étant situés d'un seul et même côté du plan P. L'angle alpha peut varier entre 3 et 20°.A reference plane P comes into contact at a point 11 with the stop means 1, at a point 12 with the roller 2 and at a point 13 with the roller 3. It will be noted that points 12 and 13 are each located on the circular end of each roll 2, 3, the further from the point 10 of intersection of the extension of axes 4 and 5. The plane P forms a dihedral angle alpha with the plane S which contains the two axes 4 and 5, these two axes being located on one and the same side of the plane P. The alpha angle can vary between 3 and 20 °.

Chaque rouleau 2, 3 a une dimension longitudinale, selon la direction de son axe respectif 4 et 5, supérieure à sa plus grande dimension transversale qui est ici uniforme et égale au diamètre du rouleau. Les deux extrémités circulaires supérieures 16 et 17 des rouleaux 2 et 3, les plus rapprochées du point d'intersection 10, sont plus rapprochées entre elles que les extrémités correspondantes 14 et 15 inférieures. Les extrémités supérieures 16, 17 définissent entre elles une ouverture de sortie 18 variable entre 1 et 50 mm, alors que les extrémités inférieures 14, 15, définissent entre elles une ouverture d'entrée 19 de taille nettement supérieure à l'ouverture de sortie 18.Each roller 2, 3 has a longitudinal dimension, in the direction of its respective axis 4 and 5, greater than its largest transverse dimension which is here uniform and equal to the diameter of the roller. The two upper circular ends 16 and 17 of the rollers 2 and 3, the closest to the point of intersection 10, are closer to each other than the corresponding lower ends 14 and 15. The upper ends 16, 17 define between them an outlet opening 18 variable between 1 and 50 mm, while the lower ends 14, 15, define between them an inlet opening 19 of size significantly larger than the outlet opening 18 .

Les rouleaux 2, 3 sont en matériau souple, en particulier élastomère ou élastomère thermoplastique. La dureté des rouleaux est de préférence comprise entre 25 et 90 shore A. Les rouleaux 2, 3 présentent des reliefs (comme expliqué avec référence aux figures de détail 6a à 9b) dont les extrémités de contact, destinées à s'appliquer sur la peau, sont espacées suivant la direction axiale et la direction périphérique de l'élément rotatif. De préférence, les extrémités de contact de deux reliefs successifs suivant la direction axiale sont décalées suivant la direction périphérique (voir figures 7b et 9b).The rollers 2, 3 are made of flexible material, in particular elastomer or thermoplastic elastomer. The hardness of the rollers is preferably between 25 and 90 shore A. The rollers 2, 3 have reliefs (as explained with reference to the detail figures 6 a to 9 b ), the contact ends of which are intended to be applied to the skin are spaced apart in the axial direction and the peripheral direction of the rotary element. Preferably, the contact ends of two successive reliefs in the axial direction are offset in the peripheral direction (see FIGS. 7 b and 9 b ).

Les rouleaux assemblés en série peuvent être de dureté variable.Rollers assembled in series can be of varying hardness.

Les figures 6a à 9b montrent plus en détail des formes diverses de rouleaux pour des appareils selon la présente invention. Les surfaces latérales des rouleaux des figures 6a à 9b présentent des reliefs. Tous ces rouleaux comportent une surface de base cylindrique droite de révolution à partir de laquelle prennent naissance différents reliefs s'étendant dans une direction radiale par rapport à l'axe de rotation du rouleau.Figures 6A to 9B show in greater detail the various forms of rolls for devices according to the present invention. The lateral surfaces rollers of Figures 6 a to 9 b have reliefs. All these rollers have a straight cylindrical base surface of revolution from which various reliefs arise which extend in a radial direction relative to the axis of rotation of the roller.

D'une manière générale, plus ces reliefs seront importants et écartés longitudinalement les uns des autres, plus l'angle alpha devra être petit et donc s'approcher de la limite inférieure prévue de 3°. En effet, dans l'action de plissé du rouleau, la peau doit entrer en contact avec une certaine étendue longitudinale du rouleau. Ces rouleaux des figures 6a à 9b, équipés de ces diverses protubérances décalées longitudinalement, ont une action vibratoire et oscillatoire sur la peau en plus de leur action de plissé-roulé, ou, dans l'autre sens, de relachêment de la peau. Cet ensemble de résultats n'a jamais été obtenu par les appareils de l'état de la technique.In general, the more these reliefs are large and separated longitudinally from each other, the smaller the angle alpha must be and therefore approach the lower limit provided for 3 °. Indeed, in the pleating action of the roller, the skin must come into contact with a certain longitudinal extent of the roller. These rollers of FIGS. 6 a to 9 b , equipped with these various protrusions offset longitudinally, have a vibratory and oscillatory action on the skin in addition to their pleated-rolled action, or, in the other direction, of loosening of the skin . This set of results has never been obtained by devices of the state of the art.

L'élément rotatif montré aux figures 6a et 6b présente un cylindre de révolution 410 autour d'un axe 411. Ce cylindre de révolution 410 s'étend dans une direction radiale par une pluralité de picots espacés 412. Ces picots s'inscrivent à la fois dans une pluralité d'enveloppes ayant chacune la forme d'un disque circulaire de même dimension, ces enveloppes géométriques étant régulièrement espacées longitudinalement les unes des autres. Dans cette forme de réalisation, les picots ont une dimension égale et, par conséquent, les extrémités 413 de tous les picots s'inscrivent dans une enveloppe cylindrique de révolution autour de l'axe 411. Ces extrémités 413 sont espacées suivant la direction axiale et la direction périphérique de l'élément rotatif.The rotary element shown in FIGS. 6 a and 6 b has a cylinder of revolution 410 around an axis 411. This cylinder of revolution 410 extends in a radial direction by a plurality of spaced spikes 412. These spikes are inscribed both in a plurality of envelopes each having the shape of a circular disc of the same dimension, these geometric envelopes being regularly spaced longitudinally from one another. In this embodiment, the pins have an equal dimension and, consequently, the ends 413 of all the pins are inscribed in a cylindrical envelope of revolution around the axis 411. These ends 413 are spaced apart in the axial direction and the peripheral direction of the rotary element.

L'élément rotatif des figures 7a et 7b présente un cylindre de révolution 415 autour de l'axe 416. Ce cylindre se prolonge dans une direction radiale par des reliefs ayant globalement la forme de carrés 417 dont les arêtes 418 ont été arrondies. Ces carrés sont régulièrement espacés l'un de l'autre selon la direction axiale du rouleau. Tous les carrés 417 ont une forme sensiblement identique mais les arêtes 418 de deux carrés successifs sont angulairement décalés d'un angle de π 4

Figure imgb0001
autour de l'axe de rotation 416. Les sommets arrondis des arêtes 418 s'inscrivent tous dans une enveloppe de révolution autour de l'axe 416.The rotary element of FIGS. 7 a and 7 b has a cylinder of revolution 415 around the axis 416. This cylinder is extended in a radial direction by reliefs generally having the form of squares 417 whose edges 418 have been rounded. These squares are regularly spaced from each other in the axial direction of the roller. All the squares 417 have a substantially identical shape but the edges 418 of two successive squares are angularly offset by an angle of π 4
Figure imgb0001
 around the axis of rotation 416. The rounded vertices of the edges 418 all fall within an envelope of revolution around the axis 416.

L'élément rotatif représenté aux figures 8a et 8b montre un cylindre de révolution 425 autour d'un axe 426. Le cylindre 425 s'étend dans une direction radiale par une pluralité de vagues 427 formant chacune une paroi continue dont le plan moyen passe par l'axe 426. Ces parois 427 possèdent un bord radial 428 en forme d'ondes se développant dans la direction longitudinale définie par l'axe 426.The rotary element shown in Figures 8 a and 8 b shows a cylinder of revolution 425 about an axis 426. The cylinder 425 extends in a radial direction by a plurality of waves 427 each forming a continuous wall whose mean plane passes through the axis 426. These walls 427 have a radial edge 428 in the form of waves developing in the longitudinal direction defined by the axis 426.

L'élément rotatif des figures 9a et 9b comporte un cylindre de révolution 430 autour d'un axe 431. Ce cylindre 430 s'étend dans une direction radiale par une pluralité de reliefs 432 ayant chacun la forme d'un disque présentant une succession de vagues s'étendant radialement. Chaque disque possède un axe de symétrie d'ordre 4 orienté selon la direction longitudinale définie par l'axe 431. Les vagues 433 de deux disques successifs sont décalées angulairement d'un angle sensiblement égal à π 4

Figure imgb0002
autour de l'axe 431.The rotary element of FIGS. 9 a and 9 b comprises a cylinder of revolution 430 around an axis 431. This cylinder 430 extends in a radial direction by a plurality of reliefs 432 each having the shape of a disc having a succession of radially extending waves. Each disc has an axis of symmetry of order 4 oriented in the longitudinal direction defined by the axis 431. The waves 433 of two successive discs are angularly offset by an angle substantially equal to π 4

La figure 1 bis montre un deuxième schéma de principe où le moyen de butée 1 a été remplacé par une seconde paire d'éléments rotatifs. Les caractéristiques analogues à celles de la figure 1 ont reçu un chiffre de référence augmenté de 100. On distingue ainsi sur cette figure, deux rouleaux 102, 103 dont les axes 104, 105 se coupent en un point 110 en formant un angle béta 1 comme défini précédemment. Ces deux axes 104, 105 définissent un plan S1.Figure 1a shows a second block diagram where the stop means 1 has been replaced by a second pair of rotating elements. The characteristics analogous to those of FIG. 1 have received a reference number increased by 100. In this figure, there are thus distinguished two rollers 102, 103 whose axes 104, 105 intersect at a point 110 in forming a beta angle 1 as defined above. These two axes 104, 105 define a plane S1.

L'appareil dont le support n'a pas été représenté comporte également deux autres éléments rotatifs 120, 121 dont le prolongement des axes concourants 122, 123 se coupent en un point 124 en formant un angle béta 2 et en déterminant ensemble un plan S2.The device, the support of which has not been shown, also comprises two other rotary elements 120, 121 whose extension of the concurrent axes 122, 123 intersect at a point 124 by forming a beta angle 2 and by determining together a plane S2.

Les plans S1, S2 sont approximativement parallèles ou forment entre eux un angle dont la valeur maximale ne dépasse pas 17°.The planes S1, S2 are approximately parallel or form between them an angle whose maximum value does not exceed 17 °.

Les quatre rouleaux 102, 103, 120, 121 d'axe 104, 105, 122, 123, sont montés librement rotatifs par rapport au support de façon qu'ils entrent en contact avec un plan P 1,2 chacun en un point de contact correspondant 112, 113, 125, 126. Ce plan P 1,2 forme un angle alpha 1 avec le plan S1 et un angle alpha 2 avec le plan S2, les angles alpha étant compris entre 3 et 20°.The four rollers 102, 103, 120, 121 of axis 104, 105, 122, 123, are mounted freely rotatable relative to the support so that they come into contact with a plane P 1.2 each at a point of contact corresponding 112, 113, 125, 126. This plane P 1.2 forms an angle alpha 1 with the plane S1 and an angle alpha 2 with the plane S2, the angles alpha being between 3 and 20 °.

Dans un même plan S, les axes des éléments rotatifs forment un angle béta compris entre 60 et 170°.In the same plane S, the axes of the rotary elements form a beta angle of between 60 and 170 °.

Les figures 2 à 4 montrent une première forme de réalisation de l'appareil selon l'invention. Les caractéristiques analogues à celles de la figure 1 portent des chiffres de référence augmentés de 200 par rapport à ceux de la figure 1. L'appareil globalement référencé par 200 comporte un plan de symétrie longitudinal X-X et comprend un manche 220 préhensible par une main. Ce manche comporte un moyen de butée 201 constitué par une saillie de la face du support destinée à être mise en regard de la peau. Cet appareil est équipé de deux éléments rotatifs se présentant sous la forme de rouleaux globalement cylindriques de révolution 202 et 203 d'axes respectifs 204 et 205, les prolongements virtuels de ces axes se coupant en un point d'intersection virtuel 210. Ces axes déterminent ensemble un angle béta 3 égal à 120°. Les rouleaux 202, 203 ainsi que la saillie 201 entrent respectivement en contact par des points de contact ou d'appui 214, 213 et 211 avec un plan P. Les axes 204, 205 définissent un plan S non représenté qui forme un angle alpha d'inclinaison avec le plan P. Cet angle alpha est ici voisin de 15°.Figures 2 to 4 show a first embodiment of the apparatus according to the invention. The characteristics analogous to those of FIG. 1 bear reference numbers increased by 200 compared to those of FIG. 1. The apparatus generally referenced by 200 has a longitudinal plane of symmetry XX and comprises a handle 220 which can be grasped by one hand. This handle includes a stop means 201 constituted by a projection of the face of the support intended to be placed opposite the skin. This device is equipped with two rotary elements in the form of generally cylindrical rollers of revolution 202 and 203 with respective axes 204 and 205, the virtual extensions of these axes intersecting at a virtual intersection point 210. These axes together determine a beta angle 3 equal to 120 °. The rollers 202, 203 and the projection 201 respectively come into contact by contact or support points 214, 213 and 211 with a plane P. The axes 204, 205 define a plane S not shown which forms an angle alpha d inclination with the plane P. This angle alpha is here close to 15 °.

Le fonctionnement de cet appareil est le suivant.The operation of this device is as follows.

On appuie cet appareil sur la peau de la manière représentée à la figure 3, la peau remplaçant alors le plan P de référence. L'appareil est tenu par son manche 220 et déplacé en translation sur la peau dans une direction parallèle au plan de symétrie X-X de l'appareil. Lorsque l'appareil est déplacé vers la droite de la figure 3, les rouleaux appuyant sur la peau en s'enfonçant légèrement dans celle-ci, roulent et glissent avec frottement sur la peau. Ce glissement avec frottement provoque un plissé de la peau qui est sollicité de la zone délimitée par la grande ouverture des rouleaux vers la zone de sortie délimitée par la petite ouverture des rouleaux. De plus, les rouleaux roulent également en provoquant un roulé de la peau. Lorsque l'appareil est déplacé dans l'autre sens, la peau ne subit pas le même massage. Les rouleaux glissent également avec frottement et roulent d'une manière simultanée mais la peau subit une légère élongation ou relâchement, avec toujours une action de roulé des rouleaux.This device is pressed on the skin as shown in Figure 3, the skin then replacing the reference plane P. The device is held by its handle 220 and moved in translation on the skin in a direction parallel to the plane of symmetry X-X of the device. When the device is moved to the right of Figure 3, the rollers pressing on the skin by sinking slightly into it, roll and slide with friction on the skin. This sliding with friction causes wrinkling of the skin which is stressed from the zone delimited by the large opening of the rollers towards the exit zone delimited by the small opening of the rollers. In addition, the rollers also roll causing the skin to roll up. When the device is moved in the other direction, the skin does not undergo the same massage. The rollers also slide with friction and roll simultaneously, but the skin undergoes a slight elongation or loosening, always with the rolling action of the rollers.

Avec l'appareil de l'invention équipé des rouleaux aux profils particuliers définis précédemment, on obtient lors du massage un mouvement oscillatoire transversal, ainsi qu'un mouvement oscillatoire vertical. Le dispositif de massage apporte un effet de drainage progressif de la peau mais de façon interrompue et avec des vibrations.With the apparatus of the invention equipped with rollers with particular profiles defined above, a transverse oscillatory movement is obtained during the massage, as well as a vertical oscillatory movement. The massage device brings a progressive drainage effect to the skin but in a way interrupted and with vibrations.

On observe, après massage avec un appareil selon l'invention, une meilleure micro-circulation entraînant une meilleure tonicité de la peau, une diminution significative de l'eau et de la graisse en surface de la peau ce qui signifie que l'appareil permet, après massage de la peau, une pénétration plus rapide du produit de massage dans l'épiderme. On observe également une augmentation de l'élasticité de la peau.After massage with an apparatus according to the invention, a better microcirculation is observed, resulting in a better tone of the skin, a significant reduction in water and fat on the surface of the skin, which means that the apparatus allows , after skin massage, faster penetration of the massage product into the epidermis. There is also an increase in the elasticity of the skin.

L'appareil de massage n'est pas agressif pour la peau.The massage device is not aggressive for the skin.

La figure 5 montre une deuxième forme de réalisation d'un appareil à deux éléments rotatifs constitués par des rouleaux. Les caractéristiques analogues à celles de la figure 2 ont reçu un chiffre de référence augmenté de 100 par rapport à ceux de la figure 2. Cet appareil globalement référencé par le chiffre 300 comporte un manche 320, un moyen de butée formant saillie 301 destinée à venir en contact avec la peau et deux éléments rotatifs sous la forme de rouleaux 302 et 303.FIG. 5 shows a second embodiment of an apparatus with two rotary elements constituted by rollers. The characteristics analogous to those of FIG. 2 have received a reference figure increased by 100 compared to those of FIG. 2. This device generally referenced by the number 300 comprises a handle 320, a stop means forming a projection 301 intended to come in contact with the skin and two rotating elements in the form of rollers 302 and 303.

Cet appareil possède un plan de symétrie longitudinal Y-Y et si l'on compare les deux appareils des figures 2 et 5 en faisant coïncider leurs plans de symétrie respectifs X-X et Y-Y, on constate que les rouleaux 302, 303 de l'appareil de la figure 5 sont symétriques des rouleaux 202, 203 de la figure 2 par rapport à un plan orthogonal au plan X-X ou Y-Y.This device has a longitudinal plane of symmetry YY and if we compare the two devices of Figures 2 and 5 by making their respective planes of symmetry XX and YY coincide, we see that the rollers 302, 303 of the device of Figure 5 are symmetrical of the rollers 202, 203 of FIG. 2 with respect to a plane orthogonal to the plane XX or YY.

L'angle d'obliquité béta 4 de l'appareil de la figure 5 est égal à l'angle d'obliquité béta 3 de l'appareil de la figure 2. Les angles d'inclinaison alpha ne sont pas représentés mais pour des raisons de symétrie, ils sont égaux. Cela signifie que les rouleaux de l'appareil de la figure 5 ont une position sur la peau symétrique par rapport à la position des rouleaux de la figure 2 et que, par conséquent, l'action de l'appareil selon la figure 5 sera sensiblement identique à celle de l'appareil de la figure 2, le roulé-plissé de l'appareil de la figure 5 étant obtenu par un déplacement vers la gauche alors que ce même roulé-plissé était obtenu par un déplacement vers la droite pour l'appareil de la figure 2.The beta obliquity angle 4 of the apparatus of FIG. 5 is equal to the beta obliquity angle 3 of the apparatus of FIG. 2. The angles of inclination alpha are not shown but for reasons of symmetry, they are equal. This means that the rollers of the device of FIG. 5 have a position on the skin which is symmetrical with respect to the position of the rollers of Figure 2 and that, therefore, the action of the apparatus according to Figure 5 will be substantially identical to that of the apparatus of Figure 2, the rolled-pleated of the apparatus of Figure 5 being obtained by a movement towards the left whereas this same rolled-pleated was obtained by a movement towards the right for the apparatus of figure 2.

Les figures 10 et 11 montrent une troisième forme de réalisation de l'appareil selon la présente invention. Cet appareil est équipé de huit éléments rotatifs identiques 419 visibles sur les figures 9a et 9b. Cet appareil globalement désigné par le chiffre de référence 500 comporte un châssis 501 recevant l'extrémité des axes 421 de chaque rouleau 419.Figures 10 and 11 show a third embodiment of the apparatus according to the present invention. This device is equipped with eight identical rotary elements 419 visible in FIGS. 9 a and 9 b . This device, generally designated by the reference number 500, comprises a chassis 501 receiving the end of the axes 421 of each roller 419.

Ces rouleaux sont disposés globalement selon deux rangées parallèles d'orientation longitudinale selon la plus grande dimension du châssis 501. Tous les rouleaux 419 sont montés librement rotatifs sur le châssis 501 de manière à ce qu'ils aient chacun un point de contact avec un plan P non représenté ici. Un rouleau 419 d'une rangée est associé à un rouleau 419 d'une autre rangée de telle manière que leurs deux axes de rotation déterminent un plan S non représenté sur les figures 10 et 11.These rollers are generally arranged in two parallel rows of longitudinal orientation along the largest dimension of the chassis 501. All the rollers 419 are freely rotatable on the chassis 501 so that they each have a point of contact with a plane P not shown here. A roller 419 of a row is associated with a roller 419 of another row so that their two axes of rotation determine a plane S not shown in FIGS. 10 and 11.

Les angles d'obliquité béta des axes des rouleaux sont tous égaux et ces axes se coupent en une pluralité de points d'intersection 502, 503, 504, 505. L'ensemble de ces points déterminent une ligne droite contenue dans un plan Q sensiblement orthogonal au plan moyen du châssis 501.The beta obliquity angles of the axes of the rollers are all equal and these axes intersect at a plurality of intersection points 502, 503, 504, 505. All of these points determine a straight line contained in a plane Q substantially orthogonal to the middle plane of chassis 501.

Les rouleaux 419 d'une rangée sont symétriques des rouleaux 419 de l'autre rangée par rapport à ce plan Q. De plus, les rouleaux d'une même rangée sont disposés régulièrement espacés selon la direction longitudinale du châssis.The rollers 419 in one row are symmetrical with the rollers 419 in the other row with respect to this plane Q. In addition, the rollers in the same row are arranged regularly spaced apart in the longitudinal direction of the chassis.

Le châssis 501 ainsi que les éléments rotatifs 419 sont recouverts par un élément de carrosserie 510 formant couvercle et élément de préhension pour la main de l'opérateur. Cet élément de carrosserie 510 est solidarisé aux extrêmités latérales 511 et longitudinales 512 du châssis 501.Chassis 501 and the elements rotary 419 are covered by a body element 510 forming a cover and a gripping element for the operator's hand. This bodywork element 510 is secured to the lateral 511 and longitudinal 512 ends of the chassis 501.

Grâce à ces caractéristiques de construction cet appareil provoquera par chacune des paires associées de ces rouleaux, une action sensiblement identique sur une portion de surface plane de la peau.Thanks to these construction characteristics, this device will cause, by each of the associated pairs of these rollers, a substantially identical action on a flat surface portion of the skin.

Lorsque l'appareil en fonctionnement tel qu'il est représenté à la figure 11, sera déplacé vers la droite, il provoquera un roulé-plissé de la peau, alors que, déplacé vers la gauche, il provoquera un relâchement et un roulé de cette dernière.When the device in operation as shown in Figure 11, will be moved to the right, it will cause a rolled-pleated skin, while, moved to the left, it will cause loosening and a roll of this last.

La figure 12 montre une quatrième forme de réalisation de l'appareil selon l'invention. Cet appareil globalement désigné sous la référence 600 comporte huit éléments rotatifs disposés selon deux rangées d'orientation longitudinales. Les prolongements des axes des éléments rotatifs coopérant ensemble se coupent deux à deux en une pluralité de points d'intersection 602, 603, 604 et 605 suivant une direction longitudinale.Figure 12 shows a fourth embodiment of the apparatus according to the invention. This device, generally designated under the reference 600, comprises eight rotary elements arranged in two rows of longitudinal orientation. The extensions of the axes of the rotary elements cooperating together intersect in pairs at a plurality of intersection points 602, 603, 604 and 605 in a longitudinal direction.

Tels que représentés à la figure 12 en partant de la gauche vers la droite dans le sens longitudinal, on distingue que les deux premiers plans S correspondant aux points 602 et 603 sont parallèles entre eux et définissent un premier groupe d'éléments rotatifs, que les plans S définis par les points d'intersection 604, 605 sont parallèles entre eux et forment un second groupe. Les points d'intersection 602, 603, 604 et 605 sont sur une ligne appartenant à un plan Q orthogonal au plan P parallèle au plan du dessin. Chaque élément d'une rangée longitudinale est disposé symétriquement par rapport à ce plan Q d'un autre élément correspondant d'une autre rangée. Les deux groupes précédents sont eux-mêmes symétriques par rapport à un plan R orthogonal à la fois au plan Q et au plan P. Le plan R et le plan Q se coupent selon une droite orthogonale au plan P (non représenté) faisant axe de symétrie d'ordre 2 pour l'appareil 600.As shown in FIG. 12 starting from the left towards the right in the longitudinal direction, one distinguishes that the first two planes S corresponding to the points 602 and 603 are parallel between them and define a first group of rotary elements, that the planes S defined by the points of intersection 604, 605 are parallel to each other and form a second group. The intersection points 602, 603, 604 and 605 are on a line belonging to a plane Q orthogonal to the plane P parallel to the plane of the drawing. Each element of a longitudinal row is arranged symmetrically with respect to this plane Q of another corresponding element of another row. The two previous groups are themselves symmetrical with respect to a plane R orthogonal to both the Q plane and the P plane. The R plane and the Q plane intersect along a line orthogonal to the P plane (not shown) forming an axis of symmetry order 2 for device 600.

Cet appareil a l'avantage de procurer un effet de massage sur la peau identique quel que soit son sens de déplacement longitudinal sur la peau.This device has the advantage of providing an identical massage effect on the skin regardless of its direction of longitudinal movement on the skin.

La figure 13 est une cinquième forme de réalisation de l'appareil selon l'invention. L'appareil globalement désigné par les chiffres de référence 700 est équipé de huit éléments rotatifs dont les angles d'obliquité et d'inclinaison tels que définis ci-dessus sont identiques. Les prolongements des axes de ces éléments rotatifs se coupent respectivement aux points 702, 703, 704. Les points d'intersection des quatre éléments rotatifs voisins centraux sont confondus dans le seul point d'intersection 703.Figure 13 is a fifth embodiment of the apparatus according to the invention. The device generally designated by the reference numbers 700 is equipped with eight rotating elements whose angles of obliquity and of inclination as defined above are identical. The extensions of the axes of these rotary elements intersect respectively at points 702, 703, 704. The points of intersection of the four central adjacent rotary elements are merged in the single point of intersection 703.

Cette variante de réalisation définit un angle d'obliquité béta et un angle d'inclinaison alpha en dépendance l'un de l'autre. Les points d'intersection 702, 703, 704 appartiennent à une même ligne droite d'orientation longitudinale, cette ligne droite définit un plan Q orthogonal au plan P parallèle au plan du dessin.This variant embodiment defines a beta obliquity angle and an angle of inclination alpha dependent on each other. The intersection points 702, 703, 704 belong to the same straight line of longitudinal orientation, this straight line defines a plane Q orthogonal to the plane P parallel to the plane of the drawing.

Dans cette forme de réalisation, les rouleaux d'une rangée sont symétriques des rouleaux d'une autre rangée par rapport à ce plan Q. D'autre part, les plans S, définis par les axes et observés successivement suivant une direction longitudinale, sont en alternance. En partant de la gauche de la figure, le premier plan S est symétrique du deuxième plan S par rapport à un plan R orthogonal au plan Q et au plan P. De même, le deuxième plan S est symétrique du troisième plan S par rapport à un plan R orthogonal au plan Q et au plan P et également, le troisième plan S est symétrique du quatrième plan S par rapport à un plan R orthogonal au plan Q et au plan P. Les quatre éléments voisins centraux dans cet appareil sont disposés selon un axe de symétrie d'ordre 4 défini par l'intersection des plans Q avec le plan R central. Cela a pour conséquence que ces quatre rouleaux fonctionnent de la même manière selon la direction longitudinale ou la direction transversale qui lui est orthogonale.In this embodiment, the rollers of a row are symmetrical of the rollers of another row with respect to this plane Q. On the other hand, the planes S, defined by the axes and observed successively in a longitudinal direction, are alternately. Starting from the left of the figure, the first plane S is symmetrical with the second plane S with respect to a plane R orthogonal to the plane Q and with the plane P. Likewise, the second plane S is symmetrical with the third plane S with respect to a plane R orthogonal to plane Q and plane P and also, the third plane S is symmetrical with the fourth plane S with respect to a plane R orthogonal to the plane Q and to the plane P. The four central neighboring elements in this apparatus are arranged along an axis of symmetry d order 4 defined by the intersection of the Q planes with the central R plane. This has the consequence that these four rollers operate in the same way in the longitudinal direction or the transverse direction which is orthogonal to it.

Il est possible de réaliser un appareil de massage contenant une pluralité de quatre éléments rotatifs associés de cette manière. Ces éléments ainsi associés formant une sorte de maille se répétant dans les directions longitudinale et transversale de l'appareil, l'action de massage des éléments rotatifs de cet appareil étant alors sensiblement identique afin que le mouvement de l'appareil se fasse dans une direction longitudinale ou transversale.It is possible to make a massage device containing a plurality of four rotary elements associated in this way. These elements thus associated forming a kind of mesh repeating in the longitudinal and transverse directions of the apparatus, the massage action of the rotary elements of this apparatus then being substantially identical so that the movement of the apparatus takes place in one direction. longitudinal or transverse.

La figure 14 montre une variante de réalisation 750 comprenant deux rangées de rouleaux 752, 754, 756 et 753, 755, 757, décalés en quinconce les uns par rapport aux autres. Les axes des rouleaux 752, 754, 756 d'une même rangée sont parallèles à une même direction tandis que les axes des rouleaux 753, 755, 757 de l'autre rangée sont parallèles à une autre direction formant l'angle d'obliquité béta avec la première direction. Un plan parallèle aux deux directions présente un angle d'inclinaison alpha par rapport au plan d'appui de l'appareil. Dans l'exemple de la figure 14, l'appareil comporte six rouleaux. Le nombre de rouleaux pourrait, bien entendu, être différent de six.FIG. 14 shows an alternative embodiment 750 comprising two rows of rollers 752, 754, 756 and 753, 755, 757, staggered relative to one another. The axes of the rollers 752, 754, 756 of the same row are parallel to the same direction while the axes of the rollers 753, 755, 757 of the other row are parallel to another direction forming the angle of obliquity beta with the first direction. A plane parallel to the two directions has an angle of inclination alpha relative to the plane of support of the device. In the example in Figure 14, the device has six rollers. The number of rollers could, of course, be different from six.

Les figures 15 et 16 montrent une autre forme de réalisation de l'appareil selon l'invention. L'appareil globalement référencé par 800 comporte huit éléments rotatifs disposés approximativement selon l'orientation de ceux déjà indiqués à la figure 12.Figures 15 and 16 show another embodiment of the apparatus according to the invention. The device generally referenced by 800 has eight rotating elements arranged approximately in the orientation of those already indicated in Figure 12.

Une première rangée est formée successivement par les éléments 801, 802, 803 et 804 ; la deuxième rangée longitudinale est formée par les éléments 805, 806, 807 et 808. Chaque couple d'éléments 801, 805 ; 802, 806 ; 803, 807 ; 804, 808 ; définissent un même angle d'inclinaison alpha. Chaque élément rotatif est monté sur un support respectif 901, 902, 903, 904, 905, 906, 907 et 908. Ces supports sont chacun montés rotatifs selon un axe perpendiculaire au plan S défini par chaque couple de rouleaux.A first row is successively formed by the elements 801, 802, 803 and 804; the second longitudinal row is formed by the elements 805, 806, 807 and 808. Each pair of elements 801, 805; 802, 806; 803, 807; 804, 808; define the same angle of inclination alpha. Each rotary element is mounted on a respective support 901, 902, 903, 904, 905, 906, 907 and 908. These supports are each mounted to rotate along an axis perpendicular to the plane S defined by each pair of rollers.

Le premier groupe de rouleaux 801, 802, 805 et 806 est relié à un premier moyen de réglage 910 de l'angle d'obliquité. Le second groupe de rouleaux 903, 904, 907, 908 est relié à un second moyen de réglage 911 de leur angle d'obliquité. Le premier moyen 910 est identique dans ses caractéristiques au second moyen 911.The first group of rollers 801, 802, 805 and 806 is connected to a first means 910 for adjusting the angle of skew. The second group of rollers 903, 904, 907, 908 is connected to a second means 911 for adjusting their angle of obliquity. The first means 910 is identical in its characteristics to the second means 911.

Le premier moyen de réglage 910 comporte deux lames flexibles élastiquement 912, 913 réunissant respectivement deux à deux les éléments supports 901 à 905 et 902 à 906 d'un même couple de rouleaux. Chaque lame 912, 913 est fixée aux environs de son milieu à une tige 914 coulissante selon la direction longitudinale. Cette tige 914 est montée coulissante dans une butée 915 et peut y être bloquée dans plusieurs positions de coulissement. A ces différentes positions de blocage correspondent des angles d'obliquité différents pour les éléments rotatifs associés 801, 802, 805 et 806.The first adjustment means 910 comprises two elastically flexible blades 912, 913 respectively joining two by two the support elements 901 to 905 and 902 to 906 of the same pair of rollers. Each blade 912, 913 is fixed around its middle to a rod 914 sliding in the longitudinal direction. This rod 914 is slidably mounted in a stop 915 and can be locked there in several sliding positions. These different locking positions correspond to different angles of obliquity for the associated rotary elements 801, 802, 805 and 806.

Le second moyen de réglage 911 a exactement la même structure que le premier moyen de blocage ci-dessus décrit et il permet également, par conséquent, le réglage à plusieurs valeurs de l'angle d'obliquité des rouleaux associés 803, 804, 807 et 808. Il est possible de conférer toujours à tous les éléments rotatifs sensiblement un même angle d'obliquité béta.The second adjustment means 911 has exactly the same structure as the first locking means described above and it therefore also allows adjustment, with several values, of the angle of inclination of the associated rollers 803, 804, 807 and 808. It is it is possible to always give all the rotating elements substantially the same beta obliquity angle.

La figure 16 montre plus précisément comment sont articulés les éléments supports 901, 905 sur le châssis 920 de l'appareil. Ce châssis comporte des alésages 921, 922 dont l'axe est orthogonal au plan S défini par les axes des rouleaux 805 et 801. Chaque élément support 901, 905 comporte une fourche 923, 924 recevant respectivement les extrémités des axes de chaque rouleau 801, 805. Chaque fourche se continue vers le bas dans sa partie centrale par un tube 925, 926 pénétrant avec frottement dans l'alésage correspondant 921, 922 en dépassant celui-ci. La partie dépassante de chaque tube 925, 926 est solidarisée à une butée 927, 928 qui appuie respectivement sur le bord de l'alésage 921, 922. La fourche 923, 924 appuie sur l'autre extrémité de l'alésage 921, 922. La lame 912 a chacune de ses extrémités 916, 917 fixée respectivement à une butée 927, 928.FIG. 16 shows more precisely how the support elements 901, 905 are articulated on the chassis 920 of the device. This chassis comprises bores 921, 922 whose axis is orthogonal to the plane S defined by the axes of the rollers 805 and 801. Each support element 901, 905 comprises a fork 923, 924 respectively receiving the ends of the axes of each roller 801, 805. Each fork is continued downwards in its central part by a tube 925, 926 penetrating with friction into the corresponding bore 921, 922 by exceeding it. The protruding part of each tube 925, 926 is secured to a stop 927, 928 which presses respectively on the edge of the bore 921, 922. The fork 923, 924 presses on the other end of the bore 921, 922. The blade 912 has each of its ends 916, 917 fixed respectively to a stop 927, 928.

La figure 17 montre une variante de réalisation d'un élément rotatif orientable où l'élément support 1005 comporte un tube 1026 introduit dans l'alésage 1022 du support et maintenu en place grâce à des ergots 1030 en débordement radial de l'extrémité inférieure de l'alésage 1022.FIG. 17 shows an alternative embodiment of a rotary adjustable element where the support element 1005 comprises a tube 1026 inserted into the bore 1022 of the support and held in place by means of lugs 1030 projecting radially from the lower end of bore 1022.

La figure 18 est une troisième variante de réalisation d'un élément rotatif orientable, le tube 1126 formant axe de rotation de l'élément support 1105 comporte un anneau en saillie sur la surface cylindrique externe de ce tube 1126, cet anneau venant s'encliqueter dans une gorge circulaire pratiquée dans l'alésage 1122 prévu dans le support 1120. Dans cette forme de réalisation, le moyen de réglage n'a pas été représenté.Figure 18 is a third alternative embodiment of a rotatable rotating element, the tube 1126 forming the axis of rotation of the support element 1105 has a ring projecting from the external cylindrical surface of this tube 1126, this ring snapping in in a circular groove made in the bore 1122 provided in the support 1120. In this embodiment, the adjustment means has not been shown.
