Description

La présente invention concerne un appareil de massage et de relaxation.The present invention relates to a massage and relaxation device.

On connaît un certain nombre d'appareils destinés au massage et à la relaxation du corps d'un utilisateur assis, incliné ou couché, et notamment les fauteuils et les lits de massage tels que décrits dans les demandes de brevet françaises FR-2 497 096, FR-2 544 610, FR-2 549 368, et FR-2 529 783 au nom de la Société Matsushita Electric Works Limited, dans la demande de brevet française FR-2 483 774 au nom de Blakeway et Olds, dans la demande de brevet française FR-2 477 870 au nom de Caillarec, dans la demande de brevet française FR-1 603 201 au nom de Desgrand, ou encore dans la demande de brevet française FR-1 596 422 au nom de Frajdenrajch. Dans tous ces documents, la technique de massage retenue consiste à venir appuyer la partie du corps à masser, en général le dos, sur un plan comprenant : soit une pluralité de rouleaux fixes disposés transversalement à l'axe du dos, soit un ensemble mobile d'au moins deux roues de massage pouvant se déplacer transversalement et longitudinalement sous la commande d'un organe d'entraînement.A number of devices are known for massaging and relaxing the body of a seated, inclined or lying user, and in particular massage chairs and beds as described in French patent applications FR-2 497 096 , FR-2 544 610, FR-2 549 368, and FR-2 529 783 in the name of Société Matsushita Electric Works Limited, in the French patent application FR-2 483 774 in the name of Blakeway and Olds, in the application French patent FR-2,477,870 in the name of Caillarec, in French patent application FR-1,603,201 in the name of Desgrand, or in French patent application FR-1,596,422 in the name of Frajdenrajch. In all of these documents, the massage technique chosen consists in pressing the part of the body to be massaged, in general the back, on a plane comprising: either a plurality of fixed rollers arranged transversely to the axis of the back, or a movable assembly at least two massage wheels which can move transversely and longitudinally under the control of a drive member.

Or, cette conception n'est pas entièrement satisfaisante car les perceptions ressenties par l'utilisateur restent très éloignées de celles procurées par un massage prodigué par un masseur professionnel ou un kinésithérapeute ; en particulier, les forces tangentielles exercées par la rotation de rouleaux ou de roues de massage sur la partie du corps à masser, même lorsque ces rouleaux ou ces roues sont recouverts d'un tapis souple, provoquent une réaction musculaire désagréable n'ayant pas d'effet relaxant. Par ailleurs, dans le cas du dos, la disposition transversale des rouleaux ou des roues de massage ne favorise pas la vascularisation des muscles dorsaux d'une manière convenable, à savoir un enrichissement sanguin dirigé vers la colonne vertébrale, améliorant la circulation du sang dans la veine cave et décongestionnant le dos. En outre, un appui continu de la partie du corps à masser sur les organes de massage, rouleaux ou roues, ne permet pas de décomprimer les muscles entre deux temps de compression, ce qui est réalisé lorsque le massage est effectué à la main ; à cet égard, il est même proposé, dans la demande de brevet française FR-2 131 084 au nom de Henri Daviau, de munir chaque organe de massage d'une suspension élastique lui permettant de s'appliquer complètement et continûment sur un point du corps quelque soit sa saillie ou sa dépression par rapport aux points voisins, ce qui contribue, d'une manière catastrophique, à un massage en force sans temps de relaxation.However, this conception is not entirely satisfactory because the perceptions felt by the user remain very far from those provided by a massage provided by a professional masseur or a physiotherapist; in particular, the tangential forces exerted by the rotation of massage rollers or wheels on the part of the body to be massaged, even when these rollers or these wheels are covered with a flexible mat, cause an unpleasant muscular reaction not having 'relaxing effect. Furthermore, in the case of the back, the transverse arrangement of the massage rollers or wheels does not favor the vascularization of the back muscles in a suitable manner, namely a blood enrichment directed towards the spine, improving the circulation of blood in the vena cava and decongestant the back. In addition, continuous support of the part of the body to be massaged on the massage organs, rollers or wheels, does not allow the muscles to be decompressed between two compression times, which is achieved when the massage is carried out by hand; in this regard, it is even proposed, in French patent application FR-2 131 084 in the name of Henri Daviau, to provide each massage member with an elastic suspension allowing it to be applied completely and continuously on one point of the body whatever its projection or its depression in relation to neighboring points, which contributes, in a catastrophic way, to a massage in force without time of relaxation.

On connaît enfin, par le brevet US-A-3 662 749, un appareil de massage et de relaxation du type d'un lit pourvu d'organes de massages comportant un faisceau de tubes parallèles entre eux, sur lesquels sont montés des galets déformables remplis d'air, par exemple en caoutchouc. Dans ce dispositif, les galets, ou boules, sont écrasées sous le poids de la zone du corps à masser, ce qui en chasse l'air, puis ils reprennent leur forme initiale par élasticité ; tout en s'écrasant, les galets d'un même tube tournent sur eux-mêmes, ce qui est censé adoucir le massage en évitant que les galets ne glissent sur le corps.Finally, from US Pat. No. 3,662,749, a massage and relaxation device of the type of a bed is provided with massage members comprising a bundle of tubes parallel to each other, on which deformable rollers are mounted. filled with air, for example rubber. In this device, the rollers, or balls, are crushed under the weight of the area of the body to be massaged, which expels the air, then they return to their initial shape by elasticity; while crushing, the rollers of the same tube rotate on themselves, which is supposed to soften the massage by preventing the rollers from sliding on the body.

On observera que cet appareil, plus avantageux que les précédents, présente encore l'inconvénient de préconiser un massage transversal du dos, plutôt qu'un massage parallèle à la colonne vertébrale. En outre, l'effet de massage procuré par un ensemble de galets, ou boules, répartis le long d'un tube demeure assez violent et, à cet égard, on comprend que la pression sur chaque galet soit encore importante lorsque le lit de massage supporte le corps de l'utilisateur couché. Enfin, la rotation de chaque galet n'est pas libre par rapport au tube ; par conséquent, sur une longueur aussi importante que celle du dos, on imagine aisément qu'il soit plus avantageux de contrôler localement la rotation de chacun des organes masseurs, plus intense sous telle ou telle vertèbre ou sous telle zone du dos. En outre, même dans le cas du massage d'autres parties du corps, il peut être important que tous les organes masseurs, galets ou autres, présentent des rotations libres indépendantes autour d'un même axe.It will be observed that this device, more advantageous than the preceding ones, still has the drawback of recommending a transverse massage of the back, rather than a massage parallel to the spine. In addition, the massage effect provided by a set of rollers, or balls, distributed along a tube remains quite violent and, in this regard, it is understood that the pressure on each roller is still important when the massage bed supports the body of the lying user. Finally, the rotation of each roller is not free relative to the tube; therefore, over a length as large as that of the back, we can easily imagine that it is more advantageous to locally control the rotation of each of the massaging organs, more intense under this or that vertebra or under such area of the back. In addition, even in the case of massage of other parts of the body, it may be important that all the massaging organs, rollers or the like, have independent free rotations about the same axis.

La présente invention vise à remédier à ces inconvénients en proposant un appareil de massage et de relaxation d'un type nouveau, muni d'organes de massage originaux procurant un massage saccadé se rapprochant de la technique employée par un masseur professionnel ou un kinésithérapeute. Ces nouveaux organes de massage permettent également aux muscles massés de réagir localement aux forces tangentielles qui peuvent s'y exercer et de limiter la compression due à leur action.The present invention aims to remedy these drawbacks by proposing a massage and relaxation device of a new type, provided with original massage organs providing a jerky massage approaching the technique employed by a professional masseur or a physiotherapist. These new massage organs also allow the massaged muscles to react locally to the tangential forces which can be exerted there and to limit the compression due to their action.

Ainsi, l'invention concerne un appareil de massage et de relaxation, horizontal, vertical, incliné, ou combinant ces diverses positions, comprenant au moins un organe de massage, maintenu dans un cadre, et contre lequel la partie du corps à masser vient en appui ; selon l'invention, chaque organe de massage comporte un ensemble de rouleaux, normalement constitués d'un mandrin cylindrique sur lequel peut tourner une gaine, préférentiellement en une substance compressible et élastique du type d'un élastomère mousse, lesdits rouleaux étant montés fous, indépendamment les uns des autres, sur au moins deux axes de rotation satellites agencés en un faisceau spiralé ou prismatique, droit ou oblique, gravitant autour d'un axe d'entraînement mû en rotation par des moyens appropriés ; par ailleurs, l'appareil selon l'invention est doté d'un bras inclinable et repliable, prolongeant, vers les pieds de l'utilisateur, le cadre supportant le ou les organes de massage, ce bras étant muni d'un pédalier permettant à l'utilisateur de fournir lui-même l'énergie nécessaire à l'entraînement en rotation du ou des organes de massage.Thus, the invention relates to a massage and relaxation device, horizontal, vertical, inclined, or combining these various positions, comprising at least one massage member, held in a frame, and against which the part of the body to be massaged support; according to the invention, each massage member comprises a set of rollers, normally consisting of a cylindrical mandrel on which a sheath can rotate, preferably made of a compressible and elastic substance of the type of a foam elastomer, said rollers being mounted idly, independently of each other, on at least two satellite axes of rotation arranged in a spiral or prismatic beam, straight or oblique, gravitating around a drive axis driven in rotation by appropriate means; moreover, the device according to the invention is provided with a tilting and folding arm, extending, towards the feet of the user, the frame supporting the massage member (s), this arm being provided with a crankset allowing the user himself to provide the energy necessary for the rotational drive of the massage member or members.

Selon une forme de réalisation préférée de l'invention, les axes de rotation satellites du ou des organes de massage sont ainsi maintenus autour de leur axe d'entraînement par deux flasques rigides transversaux solidaires dudit axe d'entraînement. Les extrémités desdits axes de rotation satellites sont fixées sur ces flasques et forment, dans le cas le plus général, les sommets d'un polygone convexe ou concave, préférentiellement irrégulier ; par exemple, ce polygone irrégulier peut être une étoile à plusieurs branches.According to a preferred embodiment of the invention, the satellite axes of rotation of the massage member (s) are thus held around their axis drive by two rigid transverse flanges integral with said drive shaft. The ends of said satellite axes of rotation are fixed on these flanges and form, in the most general case, the vertices of a convex or concave polygon, preferably irregular; for example, this irregular polygon can be a star with several branches.

Dans le cas normal d'un faisceau prismatique droit, les axes de rotation satellites sont parallèles et déterminent les arêtes des faces latérales dudit faisceau ; l'axe d'entraînement est alors également parallèle à cet ensemble d'axes satellites. La partie du corps à masser venant en appui sur les rouleaux montés sur les axes satellites, la rotation de l'axe d'entraînement engendre des secousses dont les amplitudes dépendent des distances séparant l'axe d'entraînement des axes satellites ; l'enveloppe du mouvement décrit par les rouleaux d'un organe de massage est ainsi pratiquement identique à celle qui serait décrite par un excentrique classique mû en rotation. Mais, étant donné que les rouleaux sont libres en rotation autour de l'axe satellite qui les portent, les muscles se trouvant localement en appui sur ces rouleaux viennent provoquer leur rotation à l'inverse du mouvement général imprimé par l'axe d'entraînement central de l'organe de massage ; de cette façon, on obtient une compensation assez satisfaisante des forces tangentielles habituellement exercées par des organes de massage tournants, ce qui correspond assez fidèlement au massage progressivement moins intense d'un masseur lorsqu'il termine son mouvement (un masseur alterne ainsi deux phases : après avoir comprimé les muscles en les pinçant, il les laisse en quelque sorte "fuir" sous ses doigts jusqu'à les relâcher).In the normal case of a straight prismatic beam, the satellite axes of rotation are parallel and determine the edges of the lateral faces of said beam; the drive axis is then also parallel to this set of satellite axes. The part of the body to be massed coming to rest on the rollers mounted on the satellite axes, the rotation of the drive axis generates jolts whose amplitudes depend on the distances separating the drive axis from the satellite axes; the envelope of the movement described by the rollers of a massage member is thus practically identical to that which would be described by a conventional eccentric driven in rotation. However, since the rollers are free to rotate around the satellite axis which carry them, the muscles lying locally on these rollers cause them to rotate in reverse of the general movement imparted by the drive axis central to the massage organ; in this way, a fairly satisfactory compensation is obtained for the tangential forces usually exerted by rotating massage members, which fairly faithfully corresponds to the progressively less intense massage of a masseur when he finishes his movement (a masseur thus alternates two phases: after compressing the muscles by pinching them, he lets them somehow "flee" under his fingers until they are released).

Préférentiellement, les deux bases du faisceau d'axes satellites sont constituées par tout quadrilatère du type d'un losange ou d'un rhomboïde (parallélépipède à bases rhombiques ou rhomboïdales) ; dans ce cas, les organes de massage comportent quatre axes satellites, agencés par paires aux sommets des deux diagonales des losanges extrêmes. Bien entendu, il est également possible de placer plus de quatre axes satellites autour de l'axe d'entraînement, mais on s'est aperçu que ce nombre d'axes satellites permet d'obtenir de bons résultats sans compliquer outre mesure l'organe de massage.Preferably, the two bases of the beam of satellite axes are constituted by any quadrilateral of the type of a rhombus or a rhomboid (parallelepiped with rhombic or rhomboidal bases); in this case, the massage members have four satellite axes, arranged in pairs at the vertices of the two diagonals of the extreme diamonds. Of course, it is also possible to place more than four satellite axes around the drive axis, but it has been found that this number of satellite axes makes it possible to obtain good results without excessively complicating the organ. massage.

De même, le cas d'un faisceau d'axes satellites spiralé, ou prismatique oblique, permet de varier les effets d'un organe de massage prismatique droit en introduisant une composante de massage longitudinale plus ou moins accentuée. On notera que cette disposition procure alors un effet quasiment identique à celui de roues masseuses se déplaçant dans deux directions orthogonales ; il est clair que la réalisation proposée par l'invention est beaucoup plus simple et permet, ainsi qu'il a déjà été expliqué, de compenser, au moins en partie, les compressions agissant sur les muscles massés du fait des forces tangentielles exercées par des organes de massage tournants (cas des roues masseuses).Similarly, the case of a bundle of spiral or oblique prismatic satellite axes makes it possible to vary the effects of a right prismatic massage member by introducing a more or less accentuated longitudinal massage component. It will be noted that this arrangement then gives an effect almost identical to that of massaging wheels moving in two orthogonal directions; it is clear that the embodiment proposed by the invention is much simpler and makes it possible, as has already been explained, to compensate, at least in part, for the compressions acting on the massed muscles due to the tangential forces exerted by rotating massage devices (masseuse wheels).

D'autres caractéristiques et avantages ressortiront mieux de la description qui va suivre d'une forme de réalisation d'un appareil de massage et de relaxation particulièrement adapté au massage dorsal, donnée à titre d'exemple non limitatif de la présente invention, en référence aux dessins annexés sur lesquels :

Sur les figures 1 à 3, on a représenté un appareil de massage et de relaxation particulièrement destiné au massage du dos. Cet appareil est du type d'un lit de massage, c'est-à-dire qu'il est disposé à même le sol, l'utilisateur s'y installant en position couchée (fig.3). A cet égard, l'appareil de massage et de relaxation dorsale selon l'invention est constitué autour un cadre 1 rectangulaire, disposé horizontalement dans un bâti 2 présentant deux flans verticaux 2a, fabriqués par exemple au moyen de tubes, et entretoisés par une armature intérieure 2b dont les côtés latéraux 2c forment deux rives parallèles sur lesquelles les bordures latérales 1a du cadre 1 viennent prendre appui. Le cadre 1 sert de support à deux organes de massage 3 et 4, préférentiellement parallèles, sur lesquels vient appuyer le dos de l'utilisateur par l'intermédiaire d'une toile flexible 5 (fig.3), tendue sur ledit cadre 1, la colonne vertébrale prenant place dans le plan médian desdits organes de massage 3, 4. La longueur de ces derniers est sensiblement égale à celle du cadre 1 qui correspond, elle-même, à la longueur moyenne du dos, comptée depuis les vertèbres cervicales jusqu'au sacrum.In Figures 1 to 3, there is shown a massage and relaxation device particularly intended for back massage. This device is of the type of a massage bed, that is to say that it is placed on the floor, the user settling there in the supine position (fig. 3). In this regard, the massage and back relaxation apparatus according to the invention is constituted around a rectangular frame 1, arranged horizontally in a frame 2 having two vertical blanks 2 a , manufactured for example by means of tubes, and braced by a inner frame 2 b whose lateral sides 2 c form two parallel edges on which the lateral edges 1 a of the frame 1 come to bear. The frame 1 serves as a support for two massage members 3 and 4, preferably parallel, on which the user's back is supported by means of a flexible canvas 5 (fig.3), stretched over said frame 1, the spine taking place in the median plane of said massage members 3, 4. The length of the latter is substantially equal to that of frame 1 which itself corresponds to the average length of the back, counted from the cervical vertebrae to 'at the sacrum.

Selon l'invention, les deux organes de massage 3, 4 ainsi disposés sont animés de mouvements contrarotatifs normalement dirigés vers la colonne vertébrale de l'utilisateur ; ces mouvements provoquent un afflux de sang en direction de la veine cave et favorisent la vascularisation des muscles dorsaux. Un tel principe de massage et de relaxation est tout à fait nouveau puisque, habituellement, les organes de massage sont disposés transversalement à la colonne vertébrale. A cet égard, le choix de l'entraxe des organes de massage 3, 4 n'est pas déterminant mais on conçoit aisément qu'une distance d'environ 20 centimètres soit la mieux adaptée à un massage se rapprochant de celui effectué par un masseur professionnel, chacun des organes de massage 3, 4 se trouvant alors positionné selon un axe passant entre la colonne vertébrale et une omoplate.According to the invention, the two massage members 3, 4 thus arranged are driven by counter-rotating movements normally directed towards the spine of the user; these movements cause an influx of blood towards the vena cava and promote vascularization of the back muscles. Such a principle of massage and relaxation is completely new since, usually, the massage organs are arranged transversely to the spine. In this regard, the choice of the distance between the massage members 3, 4 is not decisive, but it is easy to see that a distance of approximately 20 centimeters is best suited to a massage approaching that carried out by a masseur. professional, each of the massage members 3, 4 then being positioned along an axis passing between the spine and a scapula.

Par ailleurs, l'appareil de massage et de relaxation dorsale conforme à l'invention est doté d'un bras 6 muni d'un pédalier 7 permettant à l'utilisateur de fournir lui-même par pédalage l'énergie nécessaire à l'entraînement en rotation des deux organes de massage 3, 4. Cette caractéristique de l'invention est particulièrement bien adaptée à un massage du dos puisque le pédalage sollicite de manière très active certains des muscles dorsaux qui sont en train d'être massés, et notamment ceux situés au niveau des vertèbres lombaires ; en outre, l'utilisateur peut contrôler par la vitesse de son pédalage l'intensité et la fréquence du massage procuré le long de sa colonne vertébrale par les rotations contrarotatives des deux organes de massage 3, 4.Furthermore, the back massage and relaxation device according to the invention is provided with an arm 6 provided with a pedal unit 7 allowing the user to supply himself by pedaling the energy necessary for training. in rotation of the two massage members 3, 4. This characteristic of the invention is particularly well suited to a back massage since the pedaling very actively solicits some of the back muscles which are being massaged, and in particular those located at the level of the lumbar vertebrae; in addition, the user can control by the speed of his pedaling the intensity and the frequency of the massage provided along his spine by the counter-rotating rotations of the two massage members 3, 4.

Il est ainsi prévu un certain nombre de dispositions visant à procurer un maximum de confort à l'utilisateur. En particulier, le bras 6 est situé dans le plan médian de l'appareil de massage et de relaxation de sorte qu'il se trouve au milieu des jambes d'un utilisateur couché sur la toile flexible 5 (fig.3). A cet égard, ce bras 6 prolonge le cadre 1 vers les pieds de l'utilisateur qui peuvent ainsi accéder à deux pédales 7a s'articulant de manière classique sur deux manivelles 7b, situées de chaque côté dudit bras 6, de manière à pouvoir entraîner une roue dentée 7c en rotation autour d'un axe 7d. La roue 7c est reliée par une chaîne 7e à un pignon 7f solidaire d'un arbre de transmission 8, disposé perpendiculairement aux organes de massage 3, 4, et soutenu par des moyens courants sur l'armature intérieure 2b du bâti 2 de l'appareil de massage ; cet arbre de transmission 8 transversal est équipé d'un mécanisme de renvoi 9 à pignons coniques communiquant audits organes de massage 3, 4 leurs mouvements contrarotatifs, normalement dirigé vers la colonne vertébrale de l'utilisateur lorsque ce dernier pédale dans le sens direct.There are thus a number of provisions aimed at providing maximum comfort to the user. In particular, the arm 6 is located in the median plane of the massage and relaxation device so that it is in the middle of the legs of a user lying on the flexible fabric 5 (fig.3). In this regard, this arm 6 extends the frame 1 towards the feet of the user who can thus access two pedals 7 a articulated in a conventional manner on two cranks 7 b , located on each side of said arm 6, so as to ability to drive a toothed wheel 7 c in rotation about an axis 7 d . The wheel 7c is connected by a chain 7e to a pinion 7f secured to a transmission shaft 8, arranged perpendicular to the massage members 3, 4, and supported by current means on the internal frame 2b of the frame 2 of the massage device; this transverse transmission shaft 8 is equipped with a return mechanism 9 with bevel gears communicating with said massage members 3, 4 their counter-rotating movements, normally directed towards the spine of the user when the latter pedals in the direct direction.

Selon une autre caractéristique de l'invention non représentée sur les dessins, le pédalier 7 peut être couplé avec un moteur "d'appoint", équipé ou non d'un motoréducteur, le pignon 7f étant muni d'une roue libre, éventuellement débrayable, permettant à l'utilisateur de ne pas suivre un rythme de pédalage imposé par le moteur, tout en continuant d'être massé avec une fréquence minimale proportionnelle à sa vitesse. Un tel apport facilite l'utilisation de l'appareil de massage et de relaxation dorsale aux personnes ne pouvant pas ou ne désirant pas pédaler.According to another characteristic of the invention not shown in the drawings, the crankset 7 can be coupled with a "booster" motor, whether or not equipped with a geared motor, the pinion 7 f being provided with a free wheel, possibly disengageable, allowing the user not to follow a pedaling rhythm imposed by the motor, while continuing to be massaged with a minimum frequency proportional to its speed. Such a contribution facilitates the use of the massage and back relaxation device for people who cannot or do not wish to pedal.

Par contre, afin de permettre à tout utilisateur, petit ou grand, d'accéder aux pédales 7a du pédalier 7 lorsqu'il est couché sur la toile flexible 5, le bras 6 présente une inclinaison réglable obtenue par un système par clavetage : le bras 6 se termine ainsi par une plaque 11 s'articulant autour d'un axe horizontal 10 sur l'armature intérieure 2b du bâti 2, cette plaque 11 étant percée de trous d'indexation 11a régulièrement espacés, disposés selon un arc de cercle autour de l'axe 10, et coopérant avec un orifice 12, fixe et de même diamètre, par l'intermédiaire d'une goupille de blocage 13 amovible.On the other hand, in order to allow any user, small or large, to access the pedals 7 a of the pedal unit 7 when lying on the flexible fabric 5, the arm 6 has an adjustable inclination obtained by a keying system: the arm 6 thus ends in a plate 11 hinging about a horizontal axis 10 on the internal frame 2 b of the frame 2, this plate 11 being pierced with indexing holes 11 a regularly spaced, arranged in an arc of circle around the axis 10, and cooperating with an orifice 12, fixed and of the same diameter, by means of a removable locking pin 13.

Avantageusement, le bras 6 est complètement repliable vers l'intérieur de l'appareil de massage pour son transport (fig.2).Advantageously, the arm 6 is completely foldable towards the inside of the massage device for its transport (fig. 2).

Afin de compléter encore le confort de l'utilisateur, l'appareil de massage et de relaxation dorsale conforme à l'invention est équipé d'une têtière 14, inclinable et repliable vers l'intérieur du cadre 1 pour les mêmes raisons de transport. On a représenté, respectivement sur les figures 1 et 2, l'appareil de massage ainsi agencé, en position déployée et en position repliée, prête au transport ; on notera que, pour des raisons de clarté des figures, on a omis de dessiner la toile flexible 5 dont une représentation est, par contre, fournie sur la figure 3. A cet égard, on notera que la toile flexible 5 sur laquelle vient reposer le dos de l'utilisateur est tendue sur le cadre 1 supportant les organes de massage 3, 4 au moyen de tendeurs élastiques 5a se fixant sur le bâti 2 d'une manière amovible. En outre, cette toile flexible 5 est formée par une housse dans laquelle on peut insérer un coussin en une substance compressible élastique, du type d'une mousse connue sous le nom de "Bultex", ce qui favorise encore le confort des utilisateurs les plus sensibles.In order to further complete the comfort of the user, the back massage and relaxation device according to the invention is equipped with a headrest 14, which can be tilted and folded towards the inside of the frame 1 for the same transport reasons. There is shown, respectively in Figures 1 and 2, the massage device thus arranged, in the deployed position and in the folded position, ready for transport; it will be noted that, for reasons of clarity of the figures, we have omitted to draw the flexible fabric 5, a representation of which is, on the other hand, provided in FIG. 3. In this regard, it will be noted that the flexible fabric 5 on which comes to rest the user's back is stretched over the frame 1 supporting the massage members 3, 4 by means of elastic tensioners 5 a which are fixed to the frame 2 in a removable manner. In addition, this flexible fabric 5 is formed by a cover in which a cushion can be inserted in an elastic compressible substance, of the type of foam known under the name of "Bultex", which further promotes the comfort of the most users. sensitive.

On conçoit bien, en effet, que la massage procuré par la rotation plus ou moins rapide des organes de massage 3, 4 puisse être assez intense, tout en étant localisé, uniformément ou pas, le long de la colonne vertébrale.It is well understood, in fact, that the massage provided by the more or less rapid rotation of the massage members 3, 4 can be quite intense, while being located, uniformly or not, along the spine.

Conformément aux figures 4 et 5, chacun des organes de massage 2, 3 est préférentiellement formé par un faisceau prismatique (fig.4) ou spiralé (fig.5) d'axes satellites 14, supportant un ensemble de rouleaux 15 montés fous sur ces axes 14, ce faisceau d'axes 14 étant entraîné en rotation autour d'un axe d'entraînement 16 par l'intermédiaire de deux flasques 17 rigides transversaux sur lesquels les extrémités desdits axes satellites 14 sont fixés.In accordance with FIGS. 4 and 5, each of the massage members 2, 3 is preferably formed by a prismatic (fig. 4) or spiral (fig. 5) beam of satellite axes 14, supporting a set of rollers 15 mounted idly on these axes 14, this bundle of axes 14 being driven in rotation about a drive axis 16 by means of two rigid transverse flanges 17 on which the ends of said satellite axes 14 are fixed.

Dans la forme de réalisation préférée de l'invention, représentée sur la figure 4, les deux organes de massage 3, 4 comportent seulement quatre axes satellites 14 disposés en un faisceau parallélipipèdique droit à bases rhombiques, c'est-à-dire que les extrémités desdits axes 14 forment un losange sur les flasques 17 ; dans ce cas, l'axe d'entraînement 16 passe exactement par le milieu desdits losanges. Au cours de la rotation d'un organe de massage 3, 4 ainsi constitué, les rouleaux 15 soulèvent périodiquement la toile flexible 5 sur laquelle s'appuie le dos de l'utilisateur, y provoquant une succession de secousses dont l'amplitude dépend du décalage radial existant entre deux axes satellites 14 adjacents : dans le cas préféré de l'invention d'une répartition prismatique à bases rhombiques des axes satellites 14, on a pu établir que les sommets des losanges, formés par les extrémités desdits axes 14 sur les flasques 17, devaient présenter un décalage périodique de quelques millimètres (par exemple 10 millimètres), leur distance moyenne à l'axe d'entraînement 16 étant égale à environ 10 centimètres. Par ailleurs, conformément au détail de la figure 4, chaque rouleau 15 est préférentiellement constitué d'un mandrin 15a cylindrique, par exemple en bois ou en plastique, autour duquel peut librement tourner une gaine 15b, préférentiellement en une substance compressible et élastique du type d'un élastomère mousse. La présence de cette gaine 15b n'est pas obligatoire et l'utilisateur peut parfaitement souhaiter retirer cette dernière d'au moins certains rouleaux 15 afin d'obtenir un massage plus intense. En outre, il est préférable que les rouleaux 15 supportés par des axes satellites 14 distincts d'un même organe de massage 3 ou 4 soient presque jointifs ; de cette façon, la nappe de massage formée par la rotation de cet orgue de massage 3 ou 4 demeure raisonnablement perturbée, ce qui favorise un massage plus régulier.In the preferred embodiment of the invention, shown in FIG. 4, the two massage members 3, 4 only have four satellite axes 14 arranged in a straight parallelipiped beam with rhombic bases, that is to say that the ends of said axes 14 form a diamond on the flanges 17; in this case, the drive axis 16 passes exactly through the middle of said diamonds. During the rotation of a massage member 3, 4 thus formed, the rollers 15 periodically lift the flexible fabric 5 on which the user's back rests, causing therein a succession of tremors whose amplitude depends on the radial offset existing between two adjacent satellite axes 14: in the preferred case of the invention of a prismatic distribution with rhombic bases of the satellite axes 14, it has been possible to establish that the vertices of the diamonds, formed by the ends of said axes 14 on the flanges 17, should have a periodic offset of a few millimeters (for example 10 millimeters), their average distance to the drive axis 16 being equal to about 10 centimeters. Furthermore, in accordance with the detail in FIG. 4, each roller 15 preferably consists of a cylindrical mandrel 15 a , for example of wood or plastic, around which a sheath 15 b can freely rotate, preferably made of a compressible and elastic substance. of the type of a foam elastomer. The presence of this sheath 15b is not compulsory and the user may perfectly wish to remove the latter from at least some rollers 15 in order to obtain a more intense massage. In addition, it is preferable that the rollers 15 supported by separate satellite axes 14 of the same massage member 3 or 4 are almost contiguous; in this way, the massage table formed by the rotation of this massage organ 3 or 4 remains reasonably disturbed, which promotes a more regular massage.

Bien entendu, chaque axe satellite 14 peut supporter un certain nombre de rouleaux 15, jointifs ou non selon l'étendue de la partie du dos à masser. Dans le cas normal d'une relaxation de confort du dos, il est préférable de disposer longitudinalement quatre rouleaux 15 jointifs d'une vingtaine de centimètres sur chacun des axes satellites 14, de façon à couvrir la longueur de la colonne vertébrale d'un utilisateur d'une manière satisfaisante ; ces quatre rouleaux 15 permettent en effet de délimiter quatre zones transversales de massage, plus ou moins indépendantes, leur correspondant. En particulier, les quatre rouleaux 15 portés par un même axe satellite 14 peuvent être de diamètres hors-tout respectifs différents. Il est notamment prévu que, pour épouser la cambrure du dos de l'utilisateur installé couché sur la toile flexible 5 (fig.3), les rouleaux 15a situés sous ses vertèbres lombaires soient d'un diamètre légèrement supérieur au diamètre des rouleaux 15bsitués sous le reste du dos.Of course, each satellite axis 14 can support a number of rollers 15, whether joined or not depending on the extent of the part of the back to be massaged. In the normal case of relaxation of back comfort, it is preferable to have four contiguous rollers 15 of about twenty centimeters longitudinally on each of the satellite axes 14, so as to cover the length of the spine of a user. satisfactorily; these four rollers 15 indeed make it possible to delimit four transverse massage zones, more or less independent, their corresponding. In particular, the four rollers 15 carried by the same satellite axis 14 may have different respective overall diameters. It is in particular provided that, to match the camber of the back of the installed user lying on the flexible fabric 5 (fig. 3), the rollers 15 a situated under his lumbar vertebrae are of a diameter slightly greater than the diameter of the rollers 15 b located under the rest of the back.

Ce principe est bien entendu généralisable à toute autre réalisation des organes de massage 3 et 4, et on peut ainsi espacer les rouleaux 15, plutôt que de les juxtaposer, tout en prévoyant pour chacun un diamètre distinct des autres ; ceci permet, éventuellement, de localiser le massage ou la relaxation au niveau d'une ou d'un groupe de vertèbres (cervicales, dorsales ou lombaires), et ce d'une manière plus ou moins intense. Par exemple, dans la rééducation liée à certaines atteintes traumatologiques du dos, il peut être favorable de disposer des galets de massage plus épais de chaque côté des vertèbres à stimuler. Bien entendu, ce principe est également généralisable à tout autre massage que celui du dos, et notamment à celui des cuisses et du cou.This principle is of course generalizable to any other embodiment of the massage members 3 and 4, and it is thus possible to space the rollers 15, rather than juxtaposing them, while providing for each a diameter distinct from the others; this allows, possibly, to locate the massage or relaxation at the level of one or a group of vertebrae (cervical, dorsal or lumbar), and this in a more or less intense way. For example, in rehabilitation linked to certain trauma injuries to the back, it may be beneficial to have thicker massage rollers on each side of the vertebrae to be stimulated. Of course, this principle can also be generalized to any massage other than that of the back, and in particular that of the thighs and neck.

Dans le même ordre d'idée, on peut employer des organes de massage 3, 4 conçus différemment, et, conformément à la figure 5, il est possible d'agencer quatre axes satellites 14 en un faisceau spiralé non prismatique. Dans la disposition ici représentée, l'axe d'entraînement 16 de l'organe de massage 3, 4 est toujours placé au centre du faisceau d'axes satellites 14 qui sont fixés sur les flasques 17 de la manière suivante, donnée à titre d'exemple non limitatif : les extrémités des quatre axes satellites 14 forment, comme sur la figure 4, les sommets d'un losange mais, au montage, on a imprimé un décalage angulaire, par exemple d'un quart de tour, à l'un des deux flasques 17, après avoir fixé les axes satellites 14 comme pour réaliser l'organe de massage conforme à la figure 4. De cette façon, l'ensemble du faisceau d'axes satellites 14 présentent une "torsion" faisant en sorte que lesdits axes 14 ne se trouvent plus parallèles à l'axe d'entraînement 16.In the same vein, it is possible to use massage members 3, 4 designed differently, and, in accordance with FIG. 5, it is possible to arrange four satellite axes 14 in a non-prismatic spiral beam. In the arrangement shown here, the drive axis 16 of the massage member 3, 4 is always placed in the center of the beam of satellite axes 14 which are fixed to the flanges 17 in the following manner, given by way of 'nonlimiting example: the ends of the four satellite axes 14 form, as in Figure 4, the vertices of a rhombus but, during assembly, an angular offset was printed, for example by a quarter turn, at the one of the two flanges 17, after having fixed the satellite axes 14 as for producing the massage member in accordance with FIG. 4. In this way, the whole of the beam of satellite axes 14 have a "twist" so that said axes 14 are no longer parallel to the drive axis 16.

De multiples adaptations de l'appareil de massage et de relaxation dorsale qui vient d'être décrit sont possibles, et, notamment, il est aisé de le monter en position verticale ou inclinée pour en faire un fauteuil de massage particulièrement utile pour les personnes âgées ne pouvant pas s'allonger facilement sur un lit de massage ; dans ce cas, on agencera, par exemple, un premier cadre, tel que le cadre 1, derrière le dos de l'utilisateur, un second cadre sous les cuisses, avec des organes de massage agissant ,transversalement pour provoquer un afflux sanguin en direction du coeur, et un troisième cadre sous le cou, avec au moins un organe de massage agissant transversalement pour provoquer également un afflux sanguin en direction du coeur, tous ces cadres étant maintenus par un bâti unique et étant, le cas échéant, articulés entre eux ; en outre, la position de chacun des organes de massage, normalement deux, à l'intérieur de chaque cadre peut être réglé pour s'adapter exactement à l'anatomie de la personne. On observera également que, dans le cas d'un tel fauteuil, la motorisation annexe déjà mentionnée s'avère particulièrement utile, voire constitue le moyen d'entraînement unique des organes de massage conformes à l'invention.Multiple adaptations of the massage and back relaxation device which has just been described are possible, and, in particular, it is easy to mount it in an upright or inclined position to make it a massage chair particularly useful for the elderly. cannot be laid down easily on a massage; in this case, there will be arranged, for example, a first frame, such as frame 1, behind the user's back, a second frame under the thighs, with massage members acting, transversely to cause a blood flow in the direction of the heart, and a third frame under the neck, with at least one massage member acting transversely to also cause a blood flow towards the heart, all these frames being held by a single frame and being, where appropriate, articulated between them ; in addition, the position of each of the massage organs, normally two, inside each frame can be adjusted to adapt exactly to the anatomy of the person.
