Description

La présente invention concerne un appareil de massage de la peau du type à action mécanique comportant en combinaison des moyens de décollement du tissu conjonctif sous cutané, agissant simultanément à des moyens de brassage des parois internes dudit tissu conjonctif.The present invention relates to a skin massage device of the mechanical action type comprising, in combination, means for detaching the subcutaneous connective tissue, acting simultaneously with means for stirring the internal walls of said connective tissue.

Dans le passé il était connu de décoller le tissu conjonctif soit par des ventouses soit par jet d'air pulsé ou encore par des moyens vibrants ou encore par écrasement entre deux rouleaux, cette opération de décollement du tissu précédant celle de massage manuel qui assure le brassage des parois internes du tissu.In the past it was known to take off the connective tissue either by suction cups or by pulsed air jet or by vibrating means or by crushing between two rollers, this removal of the tissue preceding that of manual massage which ensures the mixing of the internal walls of the tissue.

Le brevet français n° 1 590 131 propose de remplacer l'opération de décollement et de brassage manuel par des moyens mécaniques associés et décrit un appareil de massage qui comporte en combinaison des moyens de succion provoquant le décollement du tissu conjonctif et des moyens de pression qui permettent la mise en contact des parois internes dudit tissu conjonctif, ces derniers moyens étant dynamiques afin d'assurer le brassage interne dans cette position.French Patent No. 1,590,131 proposes to replace the operation of detachment and manual stirring by associated mechanical means and describes a massage device which comprises in combination suction means causing the detachment of the connective tissue and pressure means which allow the internal walls of said connective tissue to be brought into contact, the latter means being dynamic in order to ensure internal mixing in this position.

De tels moyens, s'ils ont contribué au progrès technique dans ce domaine d'application, présentent néanmoins un certain nombre d'inconvénients.Such means, if they have contributed to technical progress in this field of application, nevertheless have a certain number of drawbacks.

En effet la succion provoquant l'aspiration de la peau est engendrée par une pompe à vide reliée par un tuyau souple à une conduite débouchant dans une alvéole de l'appareil, dans laquelle se loge la peau par aspiration et qui est disposée entre deux rouleaux d'entraînement aptes à brasser le pli de peau ainsi formé.In fact, the suction causing the skin to be suctioned is generated by a vacuum pump connected by a flexible hose to a pipe opening into a cell of the device, in which the skin is lodged by suction and which is arranged between two rollers. suitable for stirring the fold of skin thus formed.

En fait cette aspiration s'effectue à l'encontre de l'action des rouleaux et provoque un glissement réciproque des parois conjonctives des tissus sous-cutanés.In fact this aspiration is carried out against the action of the rollers and causes a reciprocal sliding of the connective walls of the subcutaneous tissues.

Dans un tel système l'action des rouleaux sur la peau ne s'effectue qu'à l'encontre de la force d'aspiration qui est forcement limitée et qui procure un massage trop doux dans certain cas.In such a system the action of the rollers on the skin is carried out only against the suction force which is necessarily limited and which provides a massage which is too soft in certain cases.

De plus on comprend bien qu'un tel dispositif employant une pompe à vide est forcément onéreux et encombrant.In addition, it is well understood that such a device employing a vacuum pump is necessarily expensive and bulky.

Egalement il nécessite l'adjonction d'un tuyau souple d'aspiration, qui s'ajoutant au fil électrique d'alimentation du moteur d'entraînement du rouleau, conduit à l'obtention d'un appareil de manutention mal-aisée.Also it requires the addition of a flexible suction pipe, which is added to the electrical supply wire of the drive motor of the roller, leading to the production of an uneasy handling device.

La présente invention vise à remédier à ces différents inconvénients et concerne à cet effet un appareil de massage de la peau selon la revendication 1.The present invention aims to remedy these various drawbacks and for this purpose relates to a skin massage device according to claim 1.

Le pli cutané ainsi formé entre les deux rouleaux se déplace sur la peau en même temps que l'appareil et dans le même sens que celui-ci, ce qui produit un effet de massage particulièrement efficace. Cet effet de massage est obtenu à l'aide de moyens très simples, sans aspiration et de mise en oeuvre très commode pour l'utilisateur.The skin fold thus formed between the two rollers moves on the skin at the same time as and in the same direction as the latter, which produces a particularly effective massage effect. This massage effect is obtained using very simple means, without suction and very convenient for the user.

The description which follows with reference to the appended drawings, given by way of nonlimiting example, will make it easier to understand how the invention is implemented:
  • Figure 1 is a cross-sectional view of a massage device according to the invention;
  • Figure 2 is a sectional view along the broken line II / II of Figure 1;

  • Figure 5 is a sectional view along the line V / V of Figure 3;
  • Figures 6 to 8 are simplified cross-sectional views showing the operating kinematics of the device for detachment and mixing of the fabric.

Selon un mode de réalisation préférentiel l'appareil de massage 1, désigné dans son ensemble, est constitué d'un boîtier 2 ergonomiquement conçu pour une bonne prise en main par l'utilisateur et renfermant vers l'avant AV un premier rouleau menant 3 et vers l'arrière AR un second rouleau mené 4.According to a preferred embodiment the massage device 1, designated as a whole, consists of a housing 2 ergonomically designed for a good grip by the user and enclosing for the front AV a first driving roller 3 and towards the rear AR a second driven roller 4.

Les rouleaux avant et arrière 3 et 4 sont disposés de manière sensiblement parallèle entre deux paliers respectivement 3A, 3B et 4A, 4B solidaires d'un élément du boîtier 2.The front and rear rollers 3 and 4 are arranged in a substantially parallel manner between two bearings 3A, 3B and 4A, 4B respectively secured to an element of the housing 2.

Selon l'invention, l'appareil comporte des moyens de décollement et de brassage constitués précisément par les rouleaux avant 3 et arrière 4. Le rouleau 3 constitue un rouleau menant grâce à un moteur électrique d'entraînement 5 agissant sur lui par l'intermédiaire d'un train d'engrenages démultiplicateur 6, désignés dans leur ensemble.According to the invention, the device comprises detachment and stirring means constituted precisely by the front rollers 3 and rear 4. The roller 3 constitutes a driving roller thanks to an electric drive motor 5 acting on it by means of a reduction gear train 6, designated as a whole.

Ce train est constitué schématiquement de la manière suivante:

  • un pignon moteur A entraîne un pignon B
  • le pignon B entraîne le pignon C
  • le pignon C entraîne le pignon D qui est disposé librement sur le même axe X-X′ sue le pignon B
  • le pignon D entraîne le pignon E qui est disposé librement sur le même axe Y-Y′ que le pignon C
  • le pignon E entraîne le pignon F
  • le pignon F entraîne le pignon G
  • le pignon G entraîne le pignon H qui en liaison avec le rouleau 3 par l'intermédiaire des moyens 7 sur le même axe Z Z′ dudit rouleau 3.
This train is schematically constructed as follows:
  • a drive pinion A drives a pinion B
  • the pinion B drives the pinion C
  • the pinion C drives the pinion D which is arranged freely on the same axis XX ′ on the pinion B
  • the pinion D drives the pinion E which is arranged freely on the same axis YY ′ as the pinion C
  • the pinion E drives the pinion F
  • the pinion F drives the pinion G
  • the pinion G drives the pinion H which in connection with the roller 3 via the means 7 on the same axis ZZ ′ of said roller 3.

Les diamètres et les dentures des pignons A à G sont déterminés en fonction du rapport de démultiplication recherché.The diameters and teeth of the pinions A to G are determined according to the gear ratio sought.

En tout état de cause ce rapport sera tel à obtenir une vitesse de rotation du rouleau 3 supérieure à celle du rouleau 4.In any event, this ratio will be such as to obtain a speed of rotation of the roller 3 greater than that of the roller 4.

Par conséquent le rouleau 3 est menant selon un sens de rotation F₁ identique au sens de rotation F₂ du rouleau 4 lorsqu'il est mené, lors d'un déplacement F de l'appareil, par l'intermédiaire d'un pli glissant cutané 8, qui se forme entre lesdits rouleaux 3 et 4 et se loge dans une cuvette appropriée 9 ménagée sous l'appareil 1, dès la mise en marche de celui-ci.Consequently, the roller 3 is driven in a direction of rotation F₁ identical to the direction of rotation F₂ of the roller 4 when it is driven, during a movement F of the device, by means of a skin sliding fold 8 , which forms between said rollers 3 and 4 and is housed in a suitable bowl 9 made under the apparatus 1, as soon as it is started.

En l'occurrence, la différence de vitesse de rotation entre les rouleaux avant 3 et arrière 4 est obtenue par un freinage permanent du rouleau mené 4 par l'intermédiaire de moyens de friction 10 agissant sur ce dernier 4 selon un coefficient de frottement déterminé.In this case, the difference in rotational speed between the front and rear rollers 3 and 4 is obtained by permanent braking of the driven roller 4 by means of friction means 10 acting on the latter 4 according to a determined coefficient of friction.

Ces moyens de friction 10 sont constitués par un disque 11 solidaire en rotation dudit rouleau 4 par l'intermédiaire d'un pignon 12 en liaison avec le rouleau 4 par des moyens 13 disposé sur son axe W-W′.These friction means 10 are constituted by a disc 11 integral in rotation with said roller 4 by means of a pinion 12 in connection with the roller 4 by means 13 disposed on its axis W-W ′.

Le disque 11 est mobile en translation suivant un jeu déterminé sur un axe 14, pour venir en appui librement sur une garniture fixe 15 formant un patin de freinage, par l'intermédiaire d'un organe élastique de poussée 16, tel que rondelle élastique ou ressort, taré en fonction du coefficient de friction à obtenir et ayant un rôle de compensateur automatique d'usure de la garniture 15. Le rouleau arrière mené 4 et le rouleau avant menant 3 sont disposés suivant un entraxe variable entre une distance L correspondant à une première position de pincement du pli 8 et une distance L′ correspondant à une seconde position de pincement , moins forte, dudit pli 8. Ceci est obtenu grâce à des moyens de réglage 17 (figure 4) disposés, au moins pour partie, sur le rouleau arrière 4 et qui sont constitués par des lumières 18 ménagées en vis-à-vis sur deux parois d'extrémité opposées 19 articulées sur le carter 2 par la chape 23. Les lumières 18 comportent dans le présent cas deux encoches de réglage 20 et 21 décalées entre elles angulairement et susceptibles de constituer tour à tour un palier 4A à un arbre de rotation 22 du rouleau arrière 4.The disc 11 is movable in translation according to a play determined on an axis 14, to come to bear freely on a fixed lining 15 forming a brake shoe, by means of an elastic thrust member 16, such as elastic washer or spring, calibrated according to the friction coefficient to be obtained and having the role of automatic wear compensator for the lining 15. The rear driven roller 4 and the front driving roller 3 are arranged at a variable distance between a distance L corresponding to a first pinch position of the fold 8 and a distance L ′ corresponding to a second, less strong pinch position of said fold 8. This is obtained by means of adjustment 17 (Figure 4) disposed, at least in part, on the rear roller 4 and which are constituted by slots 18 formed opposite one another on two opposite end walls 19 articulated on the casing 2 by the yoke 23. The slots 18 in this case comprise two adjustment notches 20 and 21 offset between them angularly and capable of constituting in turn a bearing 4A to a rotation shaft 22 of the rear roller 4.

Bien entendu, d'autres moyens sont possibles pour régler l'entraxe entre les deux rouleaux.Of course, other means are possible for adjusting the distance between the two rollers.

Comme on peut le constater à la comparaison des figures 2 et 3 la longueur du rouleau avant 3 offre une voie plus importante que celle du rouleau arrière 4.As can be seen from the comparison of FIGS. 2 and 3, the length of the front roller 3 offers a greater path than that of the rear roller 4.

Les rouleaux avant 3 et arrière 4 sont constitués par une succession d'éléments d'entraînement dentés 3C, 4C de profil longitudinal incurvé, dont la section transversale s'inscrit dans un cercle et comportant un logement axial 23, 24 de forme correspondant à un carré d'entraînement 23A, 24A formé par l'arbre même du rouleau 3, 4 correspondant, sur lequel sont enfilés lesdits éléments dentés 3C, 4C.The front 3 and rear 4 rollers consist of a succession of toothed drive elements 3C, 4C of curved longitudinal profile, the cross section of which is inscribed in a circle and comprising an axial housing 23, 24 of shape corresponding to a drive square 23A, 24A formed by the same shaft of the corresponding roller 3, 4, on which said toothed elements 3C, 4C are threaded.

Les éléments dentés d'entraînement 3C formant le rouleau avant menant 3 sont décalés entre eux de manière à ce que chacune des dents 3D de l'un soit disposée entre deux dents consécutives (3D) de l'autre.The toothed drive elements 3C forming the front driving roller 3 are offset from each other so that each of the 3D teeth of one is arranged between two consecutive teeth (3D) of the other.

Les éléments dentés d'entraînement 4C formant le rouleau arrière 4 peuvent également être décalés entre eux.The toothed drive elements 4C forming the rear roller 4 can also be offset from one another.

Le fonctionnement de l'appareil est basé sur le principe suivant: le rouleau avant 3 tournant plus vite que le rouleau arrière 4, pour un sens F de déplacement imposé, il est obtenu simultanément par friction, d'une part le décollement du tissu pour la constitution d'un pli cutané 8 entre lesdits rouleaux 3, 4, et d'autre part le brassage du pli 8 ainsi formé au cours d'un déplacement en translation de l'appareil 1 selon F, ayant pour effet de provoquer le glissement continu dudit pli 8 entre les rouleaux 3, 4 pour le massage d'un zone de peau correspondante.The operation of the device is based on the following principle: the front roller 3 rotating faster than the rear roller 4, for an imposed direction F of displacement, it is obtained simultaneously by friction, on the one hand the detachment of the tissue for the constitution of a skin fold 8 between said rollers 3, 4, and on the other hand the stirring of the fold 8 thus formed during a translational movement of the device 1 according to F, having the effect to cause the continuous sliding of said fold 8 between the rollers 3, 4 for the massage of a corresponding area of skin.

La mise en oeuvre d'un tel appareil de massage s'effectue de la manière suivante:

  • on met sous tension le moteur 5 ayant pour effet de faire tourner le rouleau avant 3 dans le sens F₁,
  • on pose selon le sens F₃ le rouleau arrière 4, qui est freiné et pour l'instant immobile, sur la peau 8A (figure 6),
  • on bascule l'appareil 1 en rotation selon le sens F₄ mettant en contact le rouleau avant 3 avec la peau pour initier la formation du pli 8, par son entraînement selon F₁ (figure 7)
  • la formation complète du pli 8 constituera l'organe d'entraînement par friction du rouleau freiné 4 selon le sens F₂ identique à F₁ pour un sens de déplacement F de l'appareil (figure 8).
The implementation of such a massage device is carried out as follows:
  • the motor 5 is energized, having the effect of rotating the front roller 3 in the direction F₁,
  • the rear roller 4, which is braked and for the moment immobile, is placed in the direction F₃ on the skin 8A (FIG. 6),
  • the device 1 is tilted in rotation in the direction F₄ bringing the front roller 3 into contact with the skin to initiate the formation of the fold 8, by its drive according to F₁ (FIG. 7)
  • the complete formation of the fold 8 will constitute the friction drive member of the braked roller 4 in the direction F₂ identical to F₁ for a direction of movement F of the device (FIG. 8).

Dans une version simplifiée de l'invention, le rouleau situé à l'arrière de l'appareil est remplacé par un organe présentant une surface fixe destinée à prendre appui sur la peau et adaptable pour réaliser un effet de friction avec cette peau.In a simplified version of the invention, the roller located at the rear of the device is replaced by a member having a fixed surface intended to bear on the skin and adaptable to achieve a friction effect with this skin.

Dans une autre version, le rouleau arrière est entraîné en rotation à une vitesse inférieure à celle du moteur 5 qui entraîne le rouleau 3 situé à l'avant. Il en résulte également un effet de freinage formant le pli cutané entre les deux rouleaux.In another version, the rear roller is rotated at a speed lower than that of the motor 5 which drives the roller 3 located at the front. This also results in a braking effect forming the skin fold between the two rollers.

Dans une autre variante, le rouleau arrière est remplacé par deux rouleaux entraînés en rotation par contact avec la peau, les axes de ces deux rouleaux formant entre eux un angle obtus. Cette disposition engendre lors du déplacement de l'appareil, une friction avec la peau qui forme le pli cutané recherché.In another variant, the rear roller is replaced by two rollers driven in rotation by contact with the skin, the axes of these two rollers forming an obtuse angle between them. This arrangement generates, during the movement of the device, friction with the skin which forms the desired skin fold.
