Description

DOMAINE DE L'INVENTIONFIELD OF THE INVENTION

La présente invention concerne une tête de massage, destinée à la mobilisation du tissu cutané. Elle concerne également un appareil de massage mettant en œuvre une telle tête.The present invention relates to a massage head, intended for mobilizing skin tissue. It also relates to a massage device using such a head.

L'objectif recherché par l'invention réside dans la réalisation de manière simple et efficace des opérations de massage, ce, aussi bien sur des êtres humains que sur des animaux.The objective sought by the invention lies in the simple and efficient performance of massage operations, both on human beings and on animals.

ETAT ANTERIEUR DE LA TECHNIQUEPRIOR STATE OF THE ART

On connaît différentes techniques de massage, généralement fonction des traitements à réaliser. De manière générale, elles visent à exercer sur le patient des contraintes faisant appel à des phénomènes de pression et/ou de déplacement et/ou de pincement notamment du tissu cutané.Different massage techniques are known, generally depending on the treatments to be carried out. In general, they aim to exert on the patient stresses involving phenomena of pressure and / or displacement and / or pinching, in particular of the skin tissue.

Afin de faciliter l'action du masseur, on a proposé un grand nombre de dispositifs. Parmi ceux-ci, on a tout d'abord proposé la mise en œuvre d'appareils faisant appel à une simple action mécanique, par exemple au moyen d'ensembles comportant des billes ou boules montées sur un boîtier support, permettant le cas échéant de distribuer ou d'appliquer de manière concomitante un produit de traitement de type crème ou gel, tel que par exemple décrit dans le document FR A 1 225 094 .In order to facilitate the action of the massager, a large number of devices have been proposed. Among these, it was first of all proposed the implementation of devices using a simple mechanical action, for example by means of assemblies comprising balls or balls mounted on a support housing, allowing where appropriate to distribute or apply concomitantly a treatment product of the cream or gel type, such as for example described in the document FR A 1 225 094 .

On a également proposé d'associer à ce traitement mécanique, un traitement d'aspiration de la peau du patient. A cet effet, les appareils de massage en question mettent en œuvre une tête de traitement reliée à un circuit d'aspiration, ladite tête de traitement étant constituée par un boîtier définissant une chambre interne à l'intérieur de laquelle débouche le circuit d'aspiration. Lorsque la tête de massage est appliquée contre le corps du patient, et en raison de l'aspiration générée par le circuit d'aspiration, il se forme un pli cutané à l'intérieur de la chambre interne, pli cutané qui s'appuie contre le bord périphérique de ladite chambre interne.It has also been proposed to combine this mechanical treatment with a suction treatment of the patient's skin. To this end, the massage devices in question use a treatment head connected to a suction circuit, said treatment head being constituted by a housing defining an internal chamber inside which the suction circuit opens. . When the massage head is applied against the patient's body, and due to the suction generated by the suction circuit, a skin fold is formed inside the internal chamber, a skin fold which rests against the peripheral edge of said internal chamber.

L'action mécanique, quant à elle, peut être exercée par des rouleaux, ou des billes qui permettent d'exercer concomitamment à l'aspiration sur le corps du patient, une action de pression et/ou de déplacement et/ou de friction, notamment par vibration.The mechanical action, for its part, can be exerted by rollers or balls which make it possible to exert concomitantly with the suction on the patient's body, an action of pressure and / or displacement and / or friction, especially by vibration.

Les solutions proposées dans ce contexte conduisent à des ensembles complexes, délicats à mettre en œuvre, et qui ne donnent pas entière satisfaction sur le plan des résultats.The solutions proposed in this context lead to complex sets, difficult to implement, and which are not entirely satisfactory in terms of results.

Il a également été proposé des appareils de massage susceptibles de reproduire de manière simple des massages de type palper/rouler, c'est-à-dire consistant à exercer sur le patient une action continue, provoquant non seulement un pincement localisé du tissu cutané, mais également un déplacement progressif de la zone pincée de manière à provoquer un roulage dudit pli cutané, et ce, tout en exerçant une pression (voir par exemple EP A 224 422 ).It has also been proposed massage devices capable of reproducing in a simple manner massages of the palpating / rolling type, that is to say consisting in exerting a continuous action on the patient, causing not only a localized pinching of the skin tissue, but also a gradual displacement of the pinched area so as to cause rolling of said skin fold, while exerting pressure (see for example EP A 224 422 ).

De tels appareils comportent un boîtier actionnable manuellement, à l'intérieur duquel sont montés deux rouleaux parallèles, montés libres en rotation ou entraînés positivement en rotation à l'intérieur du boîtier. Ces rouleaux peuvent être montés sur le boîtier à entraxe fixe, ou au contraire sont susceptibles de pouvoir s'écarter et se rapprocher automatiquement l'un de l'autre lors de l'opération de massage, ledit boîtier étant lui-même relié à des moyens d'aspiration permettant de créer une dépression entre lesdits rouleaux lorsque la tête munie de ces différents éléments est appliquée contre le corps du patient, ce, de façon à former un pli cutané en appui contre la surface des rouleaux.Such devices include a manually operable casing, inside which are mounted two parallel rollers, mounted free to rotate or positively driven in rotation inside the casing. These rollers can be mounted on the casing with a fixed center distance, or on the contrary are capable of being able to move apart and automatically approach one another during the massaging operation, said casing itself being connected to suction means making it possible to create a vacuum between said rollers when the head provided with these different elements is applied against the patient's body, so as to form a skin fold resting against the surface of the rollers.

Dans le document EP 0 917 452 , on a proposé de remplacer les rouleaux en question par deux cloisons rapportées à l'intérieur du boîtier, articulées au sein de ce dernier de telle sorte à pouvoir être animées d'un mouvement de pivotement, ledit boîtier étant, là encore, relié à une source d'aspiration. Sous l'action de l'aspiration, il se créé un pli cutané venant s'insérer entre les deux cloisons à l'intérieur du boîtier. En raison de la progression dans un sens ou dans l'autre de la tête de massage munie d'un tel dispositif contre la peau du patient, le pli de peau ainsi formé subit un pincement saccadé.In the document EP 0 917 452 , it has been proposed to replace the rollers in question by two partitions attached to the interior of the housing, articulated within the latter so as to be able to be driven by a pivoting movement, said housing being, here again, connected to a source of suction. Under the action of suction, a skin fold is created which is inserted between the two partitions inside the case. Due to the progression in one direction or the other of the massage head provided with such a device against the skin of the patient, the fold of skin thus formed undergoes a jerky pinching.

Ce dispositif peut être perfectionné par la mise en œuvre d'une électrovanne au niveau du circuit d'aspiration, qui permet d'obtenir un fonctionnement en «tout ou rien », mais qui permet également de définir un débit contrôlé du flux d'air entre deux valeurs déterminées avec une possibilité de réglage entre lesdites valeurs.This device can be improved by the implementation of a solenoid valve at the level of the suction circuit, which makes it possible to obtain "all or nothing" operation, but which also makes it possible to define a controlled flow rate of the air flow. between two determined values with a possibility of adjustment between said values.

Une telle électrovanne montée sur le circuit d'aspiration permet donc d'obtenir un fonctionnement séquentiel de pulsation, de rythme tel qu'au cours de l'opération de massage, le taux d'aspiration varie de manière cyclique, provoquant ainsi un effet de vibration, de variation de la force d'aspiration et de prise de peau, améliorant ainsi l'efficacité du traitement et facilitant en outre sa mise en œuvre.Such a solenoid valve mounted on the suction circuit therefore makes it possible to obtain a sequential operation of pulsation, of a rhythm such that during the massage operation, the suction rate varies cyclically, thus causing a vibration, variation of the suction force and skin grip, thus improving the effectiveness of the treatment and also facilitating its implementation.

En l'absence de contrainte, les deux cloisons sont maintenues écartées l'une de l'autre par exemple au moyen de ressorts ou d'aimants, le pivotement desdites cloisons et donc le rapprochement de l'une par rapport à l'autre résultant de l'effet du vide et/ou de la dépression générée à l'intérieur du boîtier.In the absence of constraint, the two partitions are kept apart from each other for example by means of springs or magnets, the pivoting of said partitions and therefore the approximation of one relative to the other resulting the effect of the vacuum and / or the vacuum generated inside the housing.

Afin d'améliorer encore le dispositif décrit ci-dessus, on a proposé dans le document FR 2 934 775 une tête de massage du type en question, munie de deux clapets susceptibles d'être animés d'un mouvement de pivotement de telle sorte à induire le rapprochement et l'éloignement de leur bord inférieur lorsqu'ils sont en contact avec le pli cutané, le déplacement relatif des clapets étant assuré au moyen d'une came rotative motorisée, orientée axialement par rapport à la tête de massage et dont le chemin de came dont elle est munie coopère avec lesdits clapets, de telle sorte à induire le mouvement de pivotement de ces derniers.In order to further improve the device described above, it has been proposed in the document FR 2 934 775 a massage head of the type in question, provided with two valves capable of being actuated with a pivoting movement so as to induce the approach and the distance of their lower edge when they are in contact with the skin fold, the relative movement of the valves being ensured by means of a motorized rotary cam, oriented axially with respect to the massage head and of which the cam track with which it is provided cooperates with said valves, so as to induce the pivoting movement of these latter.

Cette tête de massage permet ainsi, tout d'abord, de pouvoir s'affranchir de toute source d'aspiration. Le pli cutané résulte ainsi de l'action mécanique engendrée par le bord inférieur libre des clapets.This massage head thus makes it possible, first of all, to be able to dispense with any source of suction. The skin fold thus results from the mechanical action generated by the free lower edge of the valves.

Si incontestablement, cette tête de massage permet d'améliorer la technique du masser/pincer, en raison du mode de motorisation des clapets, il est nécessaire afin de disposer d'une amplitude plus importante de l'action des clapets, d'augmenter le diamètre de la came, et donc corollairement l'encombrement généré par la tête, affectant, d'une part, sa mise en œuvre, et d'autre part, son ergonomie.If undoubtedly, this massage head makes it possible to improve the technique of massaging / pinching, because of the motorization mode of the valves, it is necessary in order to have a greater amplitude of the action of the valves, to increase the diameter of the cam, and therefore consequently the bulk generated by the head, affecting, on the one hand, its implementation, and on the other hand, its ergonomics.

L'objectif recherché par la présente invention est, tout d'abord, d'optimiser le fonctionnement du dispositif décrit dans le document précédent, notamment en termes d'amplitude de débattement des clapets, et de leur action exercée au niveau de la peau du patient, et d'autre part, d'en diminuer l'encombrement.The objective sought by the present invention is, first of all, to optimize the operation of the device described in the preceding document, in particular in terms of the displacement amplitude of the valves, and of their action exerted on the skin of the valve. patient, and on the other hand, to reduce its size.

EXPOSE DE L'INVENTIONDISCLOSURE OF THE INVENTION

La présente invention vise donc une tête de massage comprenant un boîtier, de la partie inférieure duquel émergent deux organes actifs, dont le bord inférieur libre, opposé au boitier, est destiné à être en contact avec la peau d'un patient, l'un au moins desdits organes actifs étant constitué d'un clapet articulé au sein du boîtier et susceptible d'être animé d'un mouvement de pivotement de telle sorte à induire le rapprochement et l'éloignement l'un de l'autre des bords inférieurs libres desdits organes actifs selon une direction de déplacement relatif. Le déplacement relatif dudit au moins un clapet par rapport au boitier est assuré au moyen d'une came rotative motorisée ménagée au sein du boîtier.The present invention therefore relates to a massage head comprising a housing, from the lower part of which two active organs emerge, the free lower edge of which, opposite the housing, is intended to be in contact with the skin of a patient, one at least of said active members being constituted by a valve articulated within the housing and capable of being driven by a pivoting movement so as to induce the approach and the distance from one another of the free lower edges said active members in a direction of relative movement. The relative movement of said at least one valve relative to the housing is provided by means of a motorized rotary cam formed within the housing.

Selon l'invention :

  • l'axe de rotation de la came est orienté sensiblement parallèlement à la direction de déplacement du clapet.
  • la came comprend au moins un chemin de came présentant des ondulations, ménagé sur sa périphérie.
  • ledit clapet est monté sur un support, dont l'une des extrémités est articulée dans le boîtier, ledit support étant muni d'un organe apte à coopérer avec le chemin de came.
According to the invention:
  • the axis of rotation of the cam is oriented substantially parallel to the direction of movement of the valve.
  • the cam comprises at least one cam track having corrugations, formed on its periphery.
  • said valve is mounted on a support, one of the ends of which is articulated in the housing, said support being provided with a member capable of cooperating with the cam track.

Par organe actif, on entend tout organe destiné à venir au contact de la peau du patient, afin notamment de générer un pli cutané. Ainsi, et selon une version de l'invention, les organes actifs sont respectivement constitués d'une paroi fixe et d'un clapet, le pli cutané résultant de la seule mobilisation du clapet. Dans une version avantageuse de l'invention, les organes actifs sont tous les deux constitués d'un clapet, dont le déplacement relatif de l'un par rapport à l'autre va induire également la formation du pli de peau et son pincement, ou de manière plus générale, une mobilisation du tissu cutané.By active organ is meant any organ intended to come into contact with the patient's skin, in particular in order to generate a skin fold. Thus, and according to one version of the invention, the active organs consist respectively of a fixed wall and of a valve, the skin fold resulting from the sole mobilization of the valve. In an advantageous version of the invention, the active members both consist of a valve, the relative displacement of which with respect to the other will also induce the formation of the skin fold and its pinching, or more generally, a mobilization of the skin tissue.

En d'autres termes, l'invention consiste à ménager au sein du boîtier une came, à modifier l'orientation de la came et plus spécifiquement du ou des chemins de came dont elle est munie, ainsi que celui de son axe d'articulation, et d'autre part, de modifier la coopération entre cette came et le ou les clapets. Ainsi qu'il va être développé ci-après, ce changement de structure permet d'obtenir de manière simple une augmentation significative du débattement du bord inférieur libre du ou des clapets, ainsi que de jouer sur le couple, et donc corollairement l'effort exercé par lesdits bords inférieurs libres sur la peau du patient.In other words, the invention consists in providing a cam within the housing, in modifying the orientation of the cam and more specifically of the cam track (s) with which it is provided, as well as that of its articulation axis. , and on the other hand, to modify the cooperation between this cam and the valve (s). As will be developed below, this change in structure makes it possible to obtain, in a simple manner, a significant increase in the travel of the free lower edge of the valve (s), as well as to play on the torque, and therefore the force exerted by said free lower edges on the skin of the patient.

Selon un premier mode de réalisation de l'invention, les chemins de came sont chacun constitués d'un évidement continu ménagé à la périphérie de la came, et l'organe du support du ou des clapets coopérant avec ledit chemin de came est constitué d'au moins un ergot reçu dans ledit évidement.According to a first embodiment of the invention, the cam tracks each consist of a continuous recess formed at the periphery of the cam, and the member of the support of the valve (s) cooperating with said cam track consists of 'at least one lug received in said recess.

Selon un autre mode de réalisation de l'invention, les chemins de came sont chacun constitués d'une excroissance continue, émergeant en saillie de la périphérie de la came, et l'organe du support du ou des clapets coopérant avec le chemin de came est constitué d'au moins une fourche dont les dents se positionnent de part et d'autre de ladite excroissance.According to another embodiment of the invention, the cam tracks each consist of a continuous protuberance, projecting from the periphery of the cam, and the member of the support of the valve (s) cooperating with the cam track consists of at least one fork, the teeth of which are positioned on either side of said protuberance.

Selon une caractéristique avantageuse de l'invention, l'extrémité des organes actifs, destinée à venir en contact avec la peau du patient, est constituée d'un embout amovible fixé réversiblement soit sur le support de clapet, soit sur la paroi fixe. Ces embouts peuvent adopter différentes configurations et formes, et en outre être réalisés en un matériau souple et/ou abrasif voire susceptibles d'exciper des odeurs parfumées ou générer un effet glaçon.According to an advantageous characteristic of the invention, the end of the active organs, intended to come into contact with the patient's skin, consists of a removable end piece fixed reversibly either on the valve support or on the fixed wall. These tips can adopt different configurations and shapes, and also be made of a flexible and / or abrasive material or even capable of exuding perfumed odors or generating an ice cube effect.

Par ailleurs l'un au moins de ces embouts peut être constitué d'un rouleau libre en rotation, et dont l'axe de rotation est orienté parallèlement à l'axe d'articulation du support de clapet au sein du boîtier, ou perpendiculairement à l'axe de rotation de la came.Furthermore, at least one of these end pieces may consist of a free rotating roller, the axis of rotation of which is oriented parallel to the axis of articulation of the valve support within the housing, or perpendicular to the valve support. the axis of rotation of the cam.

Selon l'invention, la rotation de la came est assurée au moyen d'un motoréducteur monté fixe à l'intérieur de la came, et dont l'arbre de rotation du réducteur engendre la rotation d'un manchon périphérique dont est munie la came, et sur lequel sont ménagés le ou les chemins de came.According to the invention, the rotation of the cam is ensured by means of a geared motor fixedly mounted inside the cam, and whose rotation shaft of the gearbox generates the rotation of a peripheral sleeve with which the cam is provided. , and on which are provided the cam track (s).

Selon une autre alternative, la rotation de la came est assurée par une roue dentée engrenant dans un pignon solidaire de la came, ladite roue dentée étant motorisée par un moteur extérieur au boitier ou par un motoréducteur monté au sein du boitier, et dont l'arbre moteur assure la rotation de ladite roue dentée.According to another alternative, the rotation of the cam is ensured by a toothed wheel meshing with a pinion integral with the cam, said toothed wheel being motorized by a motor external to the housing or by a geared motor mounted within the housing, and of which the motor shaft rotates said toothed wheel.

L'invention vise également un dispositif de massage mettant en œuvre une telle tête de massage, et comportant une source d'énergie électrique propre à alimenter le moteur électrique actionnant lui-même le réducteur ou le moteur assurant la rotation de la came.The invention also relates to a massage device implementing such a massage head, and comprising a source of electrical energy suitable for supplying the electric motor itself actuating the reduction gear or the motor ensuring the rotation of the cam.

Ce dispositif est également susceptible de comporter une source de vide ou de dépression associée à la tête de massage, et débouchant en son sein, ledit boîtier définissant alors une chambre interne au sein de laquelle est formé le pli cutané lorsqu'elle est appliquée sur la peau d'un patient, cette chambre étant définie par deux parois latérales fixes, et par deux parois transversales constituées par les clapets et les supports de clapets.This device is also likely to include a source of vacuum or depression associated with the massage head, and opening into it, said housing then defining an internal chamber within which the skin fold is formed when it is applied to the skin. skin of a patient, this chamber being defined by two fixed side walls, and by two transverse walls formed by the valves and the valve supports.

Selon une autre caractéristique de l'invention, le boîtier de la tête de massage est solidarisé de manière réversible à la tête de massage au moyen d'organes élastiques ou clips ou systèmes équivalents, le moteur électrique et l'alimentation électrique étant confinés au niveau de la seule tête.According to another characteristic of the invention, the housing of the massage head is reversibly secured to the massage head by means of elastic members or clips or equivalent systems, the electric motor and the power supply being confined to the level. of the head alone.

DESCRIPTION DETAILLEE DE L'INVENTIONDETAILED DESCRIPTION OF THE INVENTION

On a décrit en relation avec la figure 1 une tête de massage conforme à l'invention selon sa forme la plus simpliste. Cette tête de massage (1) comporte un boîtier (2), à l'intérieur duquel sont intégrés les éléments nécessaires au fonctionnement de la tête de massage, et plus spécifiquement au déplacement de clapets (3 et 4) par rapport à ladite tête de massage (1). Ces clapets constituent les organes actifs au sens de l'invention.We have described in relation to the figure 1 a massage head according to the invention in its most simplistic form. This massage head (1) comprises a housing (2), inside which are integrated the elements necessary for the operation of the massage head, and more specifically for the movement of valves (3 and 4) relative to said control head. massage (1). These valves constitute the active members within the meaning of the invention.

Dans cette forme de réalisation simpliste, la tête de massage fonctionne limitativement mécaniquement, c'est-à-dire en l'absence de toute source d'aspiration ou de dépression, le pli cutané n'étant réalisé que par l'actionnement des clapets (3 et 4) et notamment par le rapprochement et l'éloignement de leur bord inférieur libre respectif.In this simplistic embodiment, the massage head operates limitingly mechanically, that is to say in the absence of any source of suction or depression, the skin fold only being produced by the actuation of the valves. (3 and 4) and in particular by the bringing together and the distance of their respective free lower edge.

Les figures 2 et 3 sont des vues analogues à la figure 1, sauf que la tête décrite dans celles-ci intègre un embout (6) relié à une source de dépression ou d'aspiration.The figures 2 and 3 are views analogous to the figure 1 , except that the head described therein incorporates a tip (6) connected to a vacuum or suction source.

En d'autres termes, la tête de massage conforme à l'invention est susceptible de fonctionner avec ou sans source de dépression ou d'aspiration.In other words, the massage head according to the invention is capable of operating with or without a source of vacuum or suction.

Comme indiqué en préambule, l'invention est plus particulièrement dirigée vers les moyens assurant le déplacement des clapets (3 et 4).As indicated in the preamble, the invention is more particularly directed towards the means ensuring the movement of the valves (3 and 4).

A cet effet, et ainsi qu'on peut mieux l'observer sur les figures 4 à 8, le déplacement des clapets (3 et 4) est assuré au moyen d'une came rotative (8) qui, dans cette forme de réalisation particulière, présente une enveloppe cylindrique. Cette came rotative (8) est reçue dans un support (7) lui-même solidarisé au boîtier (2).To this end, and as we can better observe it on the figures 4 to 8 , the movement of the valves (3 and 4) is ensured by means of a rotary cam (8) which, in this particular embodiment, has a cylindrical casing. This rotary cam (8) is received in a support (7) itself secured to the housing (2).

L'axe de rotation de la came rotative (8) est orienté sensiblement parallèlement à la direction de déplacement des clapets (3 et 4).The axis of rotation of the rotary cam (8) is oriented substantially parallel to the direction of movement of the valves (3 and 4).

Plus précisément, les clapets (3 et 4) sont constitués de supports de clapets (9 et 10). L'une des extrémités (20, 21) de ces supports est articulée sur le support (7), lesdites extrémités (20, 21) étant percées d'orifices traversants coopérant avec un système vis / écrous (11, 12, 18, 19) apte à assurer leur solidarisation sur le dit support, tout en permettant leur rotation par rapport à l'axe d'articulation ainsi défini.More precisely, the valves (3 and 4) consist of valve supports (9 and 10). One of the ends (20, 21) of these supports is articulated on the support (7), said ends (20, 21) being pierced with through holes cooperating with a screw / nut system (11, 12, 18, 19 ) capable of ensuring their attachment to said support, while allowing their rotation with respect to the articulation axis thus defined.

L'autre extrémité libre (22, 23) des supports (9 et 10) reçoit les embouts (14 et 15) des clapets (3 et 4), c'est-à-dire les zones actives des clapets destinées à venir en contact avec la peau du patient.The other free end (22, 23) of the supports (9 and 10) receives the end pieces (14 and 15) of the valves (3 and 4), that is to say the active areas of the valves intended to come into contact. with the patient's skin.

Ces embouts peuvent être de différentes natures et peuvent être clipsés sur lesdites extrémités (22, 23), ces dernières présentant des ergots (24) à effet élastique, aptes à coopérer avec des évidements ou organes complémentaires (non représentés) ménagés au sein desdits embouts.These end pieces can be of different types and can be clipped onto said ends (22, 23), the latter having lugs (24) having an elastic effect, able to cooperate with recesses or complementary members (not shown) formed within said end pieces. .

Ainsi, ces embouts peuvent être réalisés en différents matériaux, notamment un matériau souple et/ou abrasif, voire exciper des odeurs parfumées ou générer un effet glaçon. Ils peuvent être notamment réalisés en polypropylène, polyéthylène, polyuréthane, élastomère ou acier inoxydable.Thus, these tips can be made of different materials, in particular a flexible and / or abrasive material, or even excite perfumed odors or generate an ice cube effect. They can in particular be made of polypropylene, polyethylene, polyurethane, elastomer or stainless steel.

Le bord inférieur libre des embouts (14 et 15) peut adopter une forme convexe, afin de favoriser le contact avec la peau du patient.The free lower edge of the end pieces (14 and 15) can adopt a convex shape, in order to promote contact with the patient's skin.

Par ailleurs, l'un des embouts (14 et 15) peut être remplacé par un rouleau (5), monté libre en rotation. L'axe de rotation de ce rouleau est parallèle à l'axe d'articulation des supports de clapet au sein du boitier, et en outre perpendiculaire à l'axe de rotation de la came rotative (8).Furthermore, one of the end pieces (14 and 15) can be replaced by a roller (5), mounted to rotate freely. The axis of rotation of this roller is parallel to the axis of articulation of the valve supports within the housing, and also perpendicular to the axis of rotation of the rotary cam (8).

Comme représenté sur la figure 6 notamment, la périphérie (26) de la came rotative (8) présente deux évidements ou gorges continus (13), présentant des ondulations, et symétriques l'un de l'autre par rapport à un plan médian de la came (8). Ces évidements (13) sont destinés à coopérer avec un ou deux ergots (25), émergeant des supports de clapets (9 et 10) ainsi qu'on peut bien l'observer notamment sur les figures 7 et 8.As shown on the figure 6 in particular, the periphery (26) of the rotary cam (8) has two continuous recesses or grooves (13), having undulations, and symmetrical to one another with respect to a median plane of the cam (8). These recesses (13) are intended to cooperate with one or two lugs (25) emerging from the valve supports (9 and 10) as can be seen in particular on the figures 7 and 8 .

Dans une première configuration, les supports (9 et 10) comprennent deux ergots sensiblement médians (25), coopérant avec les chemins de came (13) selon un diamètre de ladite came (figure 7).In a first configuration, the supports (9 and 10) comprise two substantially median lugs (25), cooperating with the cam tracks (13) according to a diameter of said cam ( figure 7 ).

Selon une autre configuration représentée en figure 8, lesdits supports (9 et 10) ne comportent qu'un seul ergot (25), ne coopérant avec le chemin de came qu'en zone inférieure de la came.According to another configuration shown in figure 8 , said supports (9 and 10) have only one lug (25), cooperating with the cam track only in the lower zone of the cam.

Le choix de la mise en œuvre d'un ou de deux ergots résulte, par exemple, de la volonté de disposer davantage de couple, donc d'effort exercé par le bord inférieur libre des clapets, et partant, de l'intensité du pincement.The choice of the implementation of one or two lugs results, for example, from the desire to have more torque, and therefore the force exerted by the free lower edge of the valves, and therefore, the intensity of the pinching .

On a représenté en relation avec les figures 13 à 15 diverses variantes du chemin de came. Sur la figure 13, l'amplitude de l'ondulation des chemins de came (13), matérialisée par la distance a, est faible.We have shown in relation to the figures 13 to 15 various variations of the cam track. On the figure 13 , the amplitude of the undulation of the cam tracks (13), materialized by the distance a, is low.

Sur la figure 14, cette ondulation est plus importante. Il sera indiqué ci-après les conséquences de cette modification.On the figure 14 , this ripple is more important. The consequences of this modification will be indicated below.

Sur les figures 13 et 14, le chemin de came ne comporte que deux ondulations par tour. Sur la figure 15, le chemin de came présente quatre ondulations par tour. L'augmentation du nombre d'ondulations par tour se traduit bien évidemment par l'augmentation du nombre de pivotements des clapets par tour de rotation de la came, et donc pour une vitesse de rotation de la came donnée, par une multiplication des pivotements des clapets.On the figures 13 and 14 , the cam track has only two corrugations per revolution. On the figure 15 , the cam track has four corrugations per revolution. The increase in the number of corrugations per revolution obviously results in the increase in the number of pivotings of the valves per revolution of rotation of the cam, and therefore for a given speed of rotation of the cam, by a multiplication of the pivotings of the valves. valves.

On a représenté en relation avec les figures 11 à 12 les conséquences du positionnement respectif de ces différents éléments sur l'action exercée par les clapets sur la peau du patient. Ainsi, l'amplitude de l'ondulation a visée ci-dessus définit l'écartement El, respectivement E2 (voir figures 11 et 12) du bord inférieur libre des clapets. En d'autres termes, plus cette amplitude d'ondulation est élevée, plus la course E1-E2 du bord inférieur libre du clapet sera importante. La combinaison des longueurs L1 (longueur entre l'axe d'articulation (11, 12) du support de clapet et l'ergot (25)), L2 (longueur entre l'ergot (25) et le bord inférieur libre de l'embout du clapet) et L3 (distance séparant les deux axes d'articulation des supports de clapet) définit les écartements E1 et E2 ainsi que l'effort de pincement.We have shown in relation to the figures 11 to 12 the consequences of the respective positioning of these different elements on the action exerted by the valves on the patient's skin. Thus, the amplitude of the ripple a referred to above defines the spacing El, respectively E2 (see figures 11 and 12 ) from the lower free edge of the flaps. In other words, the higher this ripple amplitude, the greater the stroke E1-E2 of the free lower edge of the valve will be. The combination of lengths L1 (length between the hinge pin (11, 12) of the valve support and the lug (25)), L2 (length between the lug (25) and the free lower edge of the valve end) and L3 (distance separating the two hinge pins of the valve supports) defines the spacings E1 and E2 as well as the clamping force.

Il résulte de ces éléments que le constructeur peut jouer sur ces différents paramètres pour définir l'effort de pincement souhaité, et les positions des clapets ouverts et fermés.It follows from these elements that the manufacturer can play on these various parameters to define the desired clamping force, and the positions of the open and closed valves.

On a représenté en relation avec la figure 16 un autre mode de réalisation de l'invention. Dans celui-ci, les chemins de came ménagés à la périphérie (26) de la came (8) ne sont plus constitués par des évidements ou gorges, mais par des excroissances (13') faisant saillie par rapport à ladite périphérie. Dans cette hypothèse, les moyens (25) ménagés à l'intérieur des supports de clapets (9 et 10), et destinés à coopérer avec le chemin de came, ne sont plus constitués par des ergots, mais sont remplacés par une fourche, dont les deux branches viennent se positionner de part et d'autre des excroissances en saillie (13'). Le résultat obtenu en termes de déplacement des clapets est identique par rapport au mode de réalisation précédent.We have shown in relation to the figure 16 another embodiment of the invention. In the latter, the cam tracks formed at the periphery (26) of the cam (8) are no longer formed by recesses or grooves, but by protuberances (13 ') projecting from said periphery. In this hypothesis, the means (25) formed inside the valve supports (9 and 10), and intended to cooperate with the cam track, no longer consist of lugs, but are replaced by a fork, of which the two branches are positioned on either side of the protruding growths (13 '). The result obtained in terms of movement of the valves is identical with respect to the previous embodiment.

La rotation de la came (8) peut être obtenue par différents moyens. Ainsi, et selon une première forme de réalisation décrite en relation avec la figure 17, la rotation de la came (8) est obtenue au moyen d'un réducteur (27) actionné par un moteur électrique (28), l'ensemble moteur et réducteur (27, 28) étant fixé et logé à l'intérieur de la came cylindrique (8). L'arbre de sortie du réducteur est muni d'un pignon (29), qui coopère avec l'une des extrémités (31) de la came, présentant une forme (30) complémentaire au pignon (29) de l'arbre de sortie du réducteur. Dans cette hypothèse, la came est creuse pour permettre de recevoir le motoréducteur (27, 28), et la rotation de l'extrémité (31) de la came engendre la rotation d'un manchon périphérique au sein duquel sont ménagés les chemins de came (13, 13'). Ainsi, et dans cette configuration, le pignon (29) est situé dans l'axe de rotation de la came.The rotation of the cam (8) can be obtained by various means. Thus, and according to a first embodiment described in relation with the figure 17 , the rotation of the cam (8) is obtained by means of a reducer (27) actuated by an electric motor (28), the motor and reducer assembly (27, 28) being fixed and housed inside the cylindrical cam (8). The output shaft of the reducer is provided with a pinion (29), which cooperates with one of the ends (31) of the cam, having a shape (30) complementary to the pinion (29) of the output shaft of the reducer. In this hypothesis, the cam is hollow to allow the geared motor (27, 28) to be received, and the rotation of the end (31) of the cam generates the rotation of a peripheral sleeve within which the cam tracks are formed. (13, 13 '). Thus, and in this configuration, the pinion (29) is located in the axis of rotation of the cam.

L'alimentation électrique du moteur, non représentée, aboutit au niveau des parois latérales du support (7) de manière traditionnelle. Cette forme particulière de réalisation de l'invention permet de réduire très significativement l'encombrement de la tête de massage.The power supply to the motor, not shown, ends at the side walls of the support (7) in a traditional manner. This particular embodiment of the invention makes it possible to very significantly reduce the size of the massage head.

Selon un autre mode de réalisation de l'invention représenté en figure 18, la rotation de la came est obtenue là encore par un couple moteur/réducteur (27, 28), extérieur à la came, par le biais d'une roue dentée (33) montée sur l'arbre moteur du réducteur (27). Cette roue dentée engrène sur un pignon (32) solidaire de la came, et dont l'axe de rotation coïncide avec l'axe de rotation de la came. On conçoit que cette forme de réalisation engendre un encombrement plus conséquent de la tête de massage.According to another embodiment of the invention shown in figure 18 , the rotation of the cam is obtained here again by a motor / reduction gear (27, 28), external to the cam, by means of a toothed wheel (33) mounted on the motor shaft of the reduction gear (27). This toothed wheel meshes with a pinion (32) integral with the cam, and the axis of rotation of which coincides with the axis of rotation of the cam. It will be understood that this embodiment creates a larger bulk for the massage head.

Dans cette configuration, le pignon moteur denté(33) est donc déporté par rapport à l'axe de rotation de la came (8).In this configuration, the toothed motor pinion (33) is therefore offset with respect to the axis of rotation of the cam (8).

Selon encore une autre forme de réalisation de l'invention, par exemple représentée en relation avec les figures 19 à 21, la rotation de la came (8) est obtenue là encore par le principe de l'engrenage d'une roue dentée motrice (41) coopérant directement ou indirectement avec le pignon (32) de la came. Cependant, dans cette configuration, la motorisation n'est plus intégrée dans le corps (35) du boitier, mais dans la tête de massage elle-même (36), ladite tête étant désolidarisable du boitier intégrant les moyens assurant le déplacement des clapets. Cette notion de désolidarisation apparaît bien en figure 24, puisque l'on distingue dans cette hypothèse l'ensemble (43) intégrant la came rotative et les clapets, d'une part, et la tête (36), intégrant le moteur et le réducteur actionnant en rotation la roue dentée (41) d'autre part. Au niveau de cette tête (36) aboutit l'alimentation électrique (38) nécessaire au fonctionnement du moteur, et, le cas échéant, la canalisation (39) reliée à une source d'aspiration ou de dépression, logée dans un évidement (40) prévu à cet effet à des fins d'ergonomie. La solidarisation de l'ensemble (43) sur la tête (36) est effectuée au moyen de languettes élastiques ou clips (37) reçues dans des logements (42) ménagés sur deux parois opposés de l'ensemble (43), c'est-à-dire du boitier.According to yet another embodiment of the invention, for example shown in relation to the figures 19 to 21 , the rotation of the cam (8) is obtained here again by the principle of the gear of a driving toothed wheel (41) cooperating directly or indirectly with the pinion (32) of the cam. However, in this configuration, the motorization is no longer integrated in the body (35) of the box, but in the massage head itself (36), said head being detachable from the box integrating the means ensuring the movement of the valves. This concept of disconnection appears clearly in figure 24, since in this case we can distinguish the assembly (43) integrating the rotary cam and the valves, on the one hand, and the head (36), integrating the motor and the reducer. rotating the toothed wheel (41) on the other hand. At the level of this head (36) ends the electrical supply (38) necessary for the operation of the engine, and, where appropriate, the pipe (39) connected to a suction or vacuum source, housed in a recess (40 ) provided for this purpose for ergonomic purposes. The assembly (43) is secured to the head (36) by means of elastic tongues or clips (37) received in housings (42) provided on two opposite walls of the assembly (43), this is that is to say of the case.

Dans cette forme de réalisation particulière, on a représenté également par la référence (34) une chambre de traitement, avantageusement amovible, au sein de laquelle, d'une part, les clapets (3 et 4) peuvent pivoter, et d'autre part, aboutit la source d'aspiration ou de dépression. Le bord inférieur libre de la chambre de traitement est destiné à venir en contact avec la peau du patient, de telle sorte à permettre, lorsque la tête est reliée à une source d'aspiration ou de dépression, d'optimiser l'effet résultant de cette aspiration.In this particular embodiment, the reference (34) also represents a treatment chamber, advantageously removable, within which, on the one hand, the valves (3 and 4) can pivot, and on the other hand , terminates the source of aspiration or depression. The free lower edge of the treatment chamber is intended to come into contact with the patient's skin, so as to allow, when the head is connected to a suction or vacuum source, to optimize the effect resulting from this aspiration.

Dans cette forme particulière de réalisation, on observe que l'ensemble (43) ne comporte aucun constituant électrique. Ainsi donc l'ensemble (43), qui comme déjà dit est désolidarisable de la tête (36), peut être facilement nettoyé puis stérilisé. A cet effet, ses différents constituants sont réalisés dans des matériaux résistant aux produits de désinfection et à la stérilisation, tels que par exemple le polyamide, le PEEK (polyetherethercétone), le polyuréthanne thermoplastique, l'acier inoxydable. En outre, l'air aspiré dans la chambre de traitement (34) ne vient pas contaminer le système de motorisation ni les moyens de commande, intégrés dans la tête proprement dite (et non représentés).In this particular embodiment, it is observed that the assembly (43) does not include any electrical component. So the assembly (43), which as already said is detachable from the head (36), can be easily cleaned and then sterilized. To this end, its various constituents are made of materials resistant to disinfection products and sterilization, such as, for example, polyamide, PEEK (polyetheretherketone), thermoplastic polyurethane, stainless steel. In addition, the air sucked into the treatment chamber (34) does not contaminate the motorization system or the control means, integrated in the head proper (and not shown).

On conçoit tout l'intérêt de l'invention, en raison des nombreux avantages qu'elle procure.The whole interest of the invention can be seen, owing to the numerous advantages which it provides.

Tout d'abord, on aura bien compris la simplification du système de motorisation et de pivotement des clapets, outre de la diminution de l'encombrement généré par ce système. De même, on comprend bien la possibilité offerte de pouvoir jouer, par construction, sur les effets résultant de l'action des clapets, notamment en termes de vitesse de pivotement et d'effort de pincement.First of all, we will have understood the simplification of the motorization and pivoting system of the valves, in addition to the reduction in the bulk generated by this system. Likewise, it is easy to understand the possibility offered of being able to play, by construction, on the effects resulting from the action of the valves, in particular in terms of pivoting speed and clamping force.

En outre, on conçoit également que dans une version permettant de désolidariser l'aspect purement mécanique de l'aspect électrique, l'entretien, la stérilisation et le nettoyage de la tête de massage s'en trouvent grandement facilités et optimisés en termes de qualité.In addition, it can also be seen that in a version making it possible to separate the purely mechanical aspect from the electrical aspect, the maintenance, sterilization and cleaning of the massage head are greatly facilitated and optimized in terms of quality. .
