Description

La présente invention concerne un appareil de massage utilisant un liquide incompressible; comme puissance d'actionnement notamment pour usage domestique.The present invention relates to a massage device using an incompressible liquid; as actuating power especially for domestic use.

Les dispositifs connus de ce type sont généra- lement des appareils électriques dont l'usage peut être proscrit à cause des dangers inhérents à l'installation électrique. On connaît également des appareils masseurs às d'eau modulés. Ces derniers impliquent tous pour l'utilisateur une tenue de bain et utilisation dans une baignoire ou un local adté. De pius, dans les deux cas, l'amplitude deibrations fournies par ces dispositifs est relativent faible.

Figure imgb0001
Known devices of this type are generally electrical devices, the use of which may be prohibited because of the dangers inherent in the electrical installation. Modulated water massagers are also known. These all involve for the user a bathing suit and use in a bathtub or a suitable room. In addition, in both cases, the amplitude of vibrations provided by these devices is relatively small.
Figure imgb0001

L'oscillateur selon l'invention fonctionne de la façon suivante :

  • Le liquide sous pression arrivant par la canalisation d'amenée 6 va faire élever la pression dans la cavité étanche 4 et dilater une couronne de la membrane 1 comprise entre la périphérie bridée de la membrane et le bord de l'ajutage 2 portant normalement contre la face intérieure de la partie centrale de la membrane.
The oscillator according to the invention operates as follows:
  • The pressurized liquid arriving via the supply line 6 will cause the pressure in the sealed cavity 4 to increase and dilate a crown of the membrane 1 comprised between the flanged periphery of the membrane and the edge of the nozzle 2 normally bearing against the inner face of the central part of the membrane.

A partir d'une certaine pression dans la cavité 4, la membrane décolle de l'ajutage par un phénomène de battement et une fuite se produit entre le bord extérieur de l'ajutage 2 et la membrane 1. Le frottement de l'eau de fuite en circulation excite la vibration du disque central 11 de la membrane 1 qui recouvre l'ajutage 2.From a certain pressure in the cavity 4, the membrane takes off from the nozzle by a fluttering phenomenon and a leak occurs between the outer edge of the nozzle 2 and the membrane 1. The friction of the water of leak in circulation excites the vibration of the central disc 11 of the membrane 1 which covers the nozzle 2.

L'ensemble ajutage-tuyère constitue par ses dimensions un système résonant fixant la fréquence de vibration de l'appareil ; la tuyère permet également l'entretien de l'oscillation de la membrane lorsque la charge mécanique varie sur la membrane pendant l'utilisation.The nozzle-nozzle assembly constitutes by its dimensions a resonant system fixing the vibration frequency of the device; the nozzle also allows maintenance of the oscillation of the membrane when the mechanical load varies on the membrane during use.

De fait, dans l'appareil selon l'invention, la membrane 1 constitue l'organe d'application de vibrations sur le matériau à agiter ou à masser, tout en définissant la paroi d'extrémité frontale de l'appareil. Dans le cas d'un appareil de massage, comme représenté sur Ia figure 2, l'appareil se présente donc sous la forme d'un applicateur avec une partie de corps servant à sa manipulation, l'extrémité constituée par la membrane étant destinée à être appliquée sur les zones du corps à masser, permettant ainsi une application localisée et efficace.In fact, in the apparatus according to the invention, the membrane 1 constitutes the member for applying vibrations to the material to be agitated or to be massaged, while defining the front end wall of the apparatus. In the case of a massage device, as shown in FIG. 2, the device is therefore in the form of an applicator with a body part used for its manipulation, the end formed by the membrane being intended to be applied to the areas of the body to be massaged, allowing a localized and effective application.

La chambre tampon 8 sert, d'une part, de réservoir de fluide régulant la contre-pression en aval de l'ajutage, et, d'autre part, à recueillir l'eau qui s'échappe de la tuyère 7 pour l'évacuer vers l'extérieur de l'appareil, par le tube 9.The buffer chamber 8 serves, on the one hand, as a fluid reservoir regulating the back pressure downstream of the nozzle, and, on the other hand, to collect the water which escapes from the nozzle 7 for the evacuate to the outside of the device, through tube 9.

On a représenté sur la figure 2, un mode de réalisation pratique d'un appareil de massage selon l'invention. La conception générale est tout à fait identique à celle du mode de réalisation de la figure 1,.sinon que l'on notera que la canalisation d'amenée 6 est pourvue d'un dispositif de connexion rapide 12 à un flexible 13 d'une installation de distribution domestique, par exemple un flexible de douche, Il en est de même pour le tube d'évacuation 9 qui est prolongé par une tubulure d'évacuation souple 14 qui permet de rejeter l'eau dans une baignoire ou un lavabo. Pour faciliter et contrôler le montage en tension de la membrane 1, il est prévu, ici, entre le corps 5 et la périphérie à brider de la membrane, un élément d'entretoise intercalaire annulaire 15 tout d'abord vissé dans le couvercle 3 pour pincer la périphérie de la membrane, l'ensemble couvercle-entretoise- membrane étant vissé sur la périphérie du corps 5 pour assurer la mise en tension requise de la membrane, un joint étant avantageusement prévu pour assurer l'étanchéité.FIG. 2 shows a practical embodiment of a massage device according to the invention. The general design is completely identical to that of the embodiment of FIG. 1, except that it will be noted that the supply pipe 6 is provided with a quick connection device 12 to a flexible pipe 13 of a domestic distribution installation, for example a shower hose, It is the same for the drain tube 9 which is extended by a flexible drain pipe 14 which allows water to be discharged into a bathtub or sink. To facilitate and control the tensioning of the membrane 1, an annular spacer element 15 is first screwed into the cover 3 between the body 5 and the periphery to be clamped of the membrane. pinch the periphery of the membrane, the cover-spacer-membrane assembly being screwed onto the periphery of the body 5 to ensure the required tensioning of the membrane, a seal being advantageously provided for sealing.

La membrane 1 peut être avantageusement réalisée en caoutchouc synthétique ou naturel avec une épaisseur comprise entre 1 et 2,5 mm, typiquement de 2 mm et est tendue au montage avec une force de 3 à 10 kg sur l'ajutage 2, lequel présente une section divergeant vers l'extérieur sous un angle de 34°, avec un diamètre de passage extérieur de 21,7 mm et un diamètre de passage intérieur de 12 mm. Dans ces conditions, la tuyère 7 est cylindrique et a un diamètre intérieur de 12 mm et une longueur de 67 mm. Cet agencement permet de générer des vibrations avec une fréquence de fondamental comprise entre 50 et 100 Hertz et un pic de haut niveau pour l'harmonique 9. L'amplitude crête à crête de la vibration de la membrane peut atteindre 2 mm.The membrane 1 can advantageously be made of synthetic or natural rubber with a thickness between 1 and 2.5 mm, typically 2 mm and is stretched for mounting with a force of 3 to 10 kg on the nozzle 2, which has a section diverging towards the outside at an angle of 34 °, with an outside passage diameter of 21.7 mm and an inside passage diameter of 12 mm. Under these conditions, the nozzle 7 is cylindrical and has an internal diameter of 12 mm and a length of 67 mm. This arrangement makes it possible to generate vibrations with a fundamental frequency between 50 and 100 Hertz and a high level peak for the harmonic 9. The peak-to-peak amplitude of the vibration of the membrane can reach 2 mm.

L'appareil peut également être utilisé comme élément vibrant pour favoriser des mélanges ou des dissolutions de produits pour lesquels le courant électrique constituerait également un danger.The device can also be used as a vibrating element to promote mixtures or dissolutions of products for which the electric current would also constitute a danger.

Selon un aspect de l'invention, l'appareil convient tout particulièrement pour l'application de massages très doux, par exemple pour les soins du visage, avec une amplitude d'oscillations de quelques dizièmes de millimètres, aussi bien que pour l'application de massages très énergiques à la puissance maximum, en ouvrant complètement le robinet d'alimentation de l'installation d'eau domestique. L'appareil peut servir dans tous les cas de massage. Il est de même possible de se masser dans l'eau ou sous l'eau, par exemple en prenant son bain, sans le moindre risque d'électrocution. Selon un des objets de l'invention, en raison de l'absence de projection d'eau, il est également possible d'effectuer des massages en demeurant tout habillé ; dans ce cas, la grande amplitude de la vibration émise permet le passage de l'énergie à travers les vêtements. L'importance de l'amplitude des vibrations de basse fréquence qu'il génère, et la possibilité de massage en utilisant' l'eau chaude en font un appareil particulièrement efficace dans les traitements d'assistance à l'amaigrissement, notamment pour le traitement de la cellulite.According to one aspect of the invention, the device is particularly suitable for the application of very gentle massages, for example for facial treatments, with an amplitude of oscillations of a few tenths of a millimeter, as well as for the application very energetic massages at maximum power, by fully opening the supply tap of the domestic water installation. The device can be used in all massage cases. It is also possible to massage in or under water, for example while taking a bath, without the slightest risk of electrocution. According to one of the objects of the invention, due to the absence of water projection, it is also possible to perform massages while remaining fully clothed; in this case, the large amplitude of the vibration emitted allows the passage of energy through the clothing. The importance of the amplitude of the low frequency vibrations it generates, and the possibility of massage using hot water make it a particularly effective device in weight loss assistance treatments, especially for treatment cellulite.

Quoique la présente invention ait été décrite en relation avec des modes de réalisation particuliers, elle ne s'en trouve pas limitée mais est au contraire susceptible de modifications et de variantes qui apparaîtront à l'homme de l'art.Although the present invention has been described in relation to particular embodiments, it is not limited thereto but is on the contrary subject to modifications and variants which will appear to those skilled in the art.
