Abstract
Description
La présente invention est relative à un matelas de relaxation, adapté notamment à soutenir un usager en flottaison entre deux eaux de telle sorte que la majeure partie de son corps soit immergée juste sous la surface de l'eau, seule restant émergée en position allongée sur le matelas la face de cet usager et en particulier le nez et la bouche de celui-ci.The present invention relates to a relaxation mattress, adapted in particular to support a user floating between two waters so that most of his body is immersed just below the surface of the water, only remaining emerged in the lying position on the mattress the face of this user and in particular the nose and the mouth thereof.
On connaît les avantages de la relaxation corporelle, tant d'un point de vue physique que psychique. On sait également que cette relaxation s'effectue de façon d'autant plus efficace que le corps de l'individu est placé dans un environnement qui exerce sur lui une action douce de massage ou simplement de support équilibré. L'utilisation des techniques de flottaison est à cet égard particulièrement utile, en permettant de maintenir le corps dans un milieu ambiant dont la température, la teneur en sel ou autres agents minéraux, la densité, etc... peuvent être ajustées à la demanda. De même, indépendamment des utilisations à finalité médicale ou de traitement, on connaît l'agrément que procure l'emploi de matelas flottants pour usage en piscine ou au bord de mer.We know the benefits of physical relaxation, both physically and mentally. We also know that this relaxation takes place all the more effectively when the body of the individual is placed in an environment which exerts on it a gentle massage action or simply a balanced support. The use of flotation techniques is particularly useful in this respect, allowing the body to be maintained in an ambient environment whose temperature, salt or other mineral agent content, density, etc. can be adjusted on demand. . Likewise, independently of the uses for medical or treatment purposes, we know the pleasure that comes with the use of floating mattresses for use in swimming pools or at the seaside.
Toutefois, ces objets bien connus généralement constitués d'une enveloppe en caoutchouc ou matière plastique étanche, gonflée à l'air, ne permettent pas une flottaison entre deux eaux de celui qui utilise le matelas et surtout n'autorisent pas le maintien du corps de l'usager en position parfaitement allongée, en raison des différences qui existent entre le poids des diverses parties de son corps qui exercent sur le matelas des efforts d'intensité distincts et modifient en conséquence la planéité du matelas. Dans le cas en particulier des applications médicales de tels matelas, celles-ci sont de ce fait généralement exclues, ces matelas constituant plus dans leur forme classique des objets de jeux que des instruments efficaces et médicalement reconnus de détente et de relaxation.However, these well-known objects generally consisting of a rubber or waterproof plastic envelope, inflated with air, do not allow flotation between two waters of the one who uses the mattress and above all do not allow the body to be maintained. the user in a perfectly lying position, due to the differences which exist between the weight of the various parts of his body which exert on the mattress efforts of distinct intensity and consequently modify the flatness of the mattress. In the particular case of medical applications of such mattresses, these are therefore generally excluded, these mattresses constituting more in their classic form of play objects than effective and medically recognized instruments of relaxation and relaxation.
L'invention a pour objet un matelas de relaxation qui évite ces inconvénients en permettant notamment une flottaison du corps d'un usager allongé sur le matelas s'effectuant entre deux eaux, avec un maintien de ce corps parfaitement à plat, ce dernier conservant en tous points de sa surface une forme plane ou très sensiblement plane.The subject of the invention is a relaxation mattress which avoids these drawbacks by in particular allowing the body of a user lying on the mattress to float between two waters, with this body being held in place. perfectly flat, the latter retaining at all points of its surface a planar or very substantially planar shape.
A cet effet, le matelas considéré se caractérise en ce qu'il comporte deux couches sucessives accolées et superposées formée chacune d'une enveloppe étanche et dont la première , laquelle est destinée à recevoir le corps de l'usager, contient une pluralité de bulles d'air contiguës mais séparées, présentant un volume sensiblement identique en tous points de ladite couche, et la seconde comprend des bulles d'air également contiguës et séparées mais de volumes différents selon leur localisation dans cette couche, les bulles de la seconde couche présentant un volume proportionnel à la densité relative des différentes parties du corps de l'usager allongé sur le matelas.To this end, the mattress considered is characterized in that it comprises two successive layers placed side by side and superimposed each formed of a waterproof envelope and the first of which, which is intended to receive the body of the user, contains a plurality of bubbles of contiguous but separate air, having a substantially identical volume at all points of said layer, and the second comprises air bubbles also contiguous and separate but of different volumes depending on their location in this layer, the bubbles of the second layer having a volume proportional to the relative density of the different parts of the body of the user lying on the mattress.
Ainsi, en prévoyant dans la seconde couche disposée sous la première,des bulles d'air de volumes variables selon l'étendue de la couche, on assure un support adapté du corps de l'usager allongé sur le matelas en exerçant à l'encontre du poids de celui-ci, du fait de la poussée d'Archimède, un effort variable plus important vers les parties du corps les plus denses telles que la tête, le bassin,.le tronc et moins élevé sur les autres parties.Thus, by providing air bubbles of variable volumes depending on the extent of the layer in the second layer placed under the first, it provides suitable support for the body of the user lying on the mattress, working against of its weight, due to Archimedes' push, a greater variable effort towards the densest parts of the body such as the head, the pelvis, the trunk and lower on the other parts.
On réalise ainsi une stabilisation de l'usager en position idéale, parfaitement plane, facilitant de manière sensible l'effet de relaxation recherché, avec une amélioration notable de la réaction opposée par le matelas au poids qu'il supporte. Notamment, il devient ici possible d'épouser la forme du corps en tous points de celui-ci et plus spécialement d'assurer un soutien de la colonne vertébrale de l'usager en une position exactement horizontale, cette partie du corps constituant une zone particulièrement sensible et dont l'effet sur la relaxation de l'usager est tout à fait primordial.This stabilizes the user in an ideal position, perfectly flat, significantly facilitating the desired relaxation effect, with a significant improvement in the reaction opposed by the mattress to the weight it supports. In particular, it becomes possible here to follow the shape of the body at all points thereof and more especially to provide support for the spine of the user in an exactly horizontal position, this part of the body constituting a particularly zone sensitive and whose effect on the relaxation of the user is absolutely essential.
Selon une caractéristique particulière de l'invention, le matelas présente une forme géométrique adaptée à la morphologie générale du corps de l'usager avec notamment un évidement de part et d'autre des jambes de celui-ci.According to a particular characteristic of the invention, the mattress has a geometric shape adapted to the general morphology of the user's body with in particular a recess on either side of the legs thereof.
En particulier, le matelas présente une partie plus étroite sous la tête et le tronc de l'usager pour permettre le libre passage des bras de celui-ci et une partie plus élargie sous le tronc et de part et d'autre des jambes de l'utilisateur.In particular, the mattress has a narrower part under the head and the trunk of the user to allow free passage of the arms of the latter and a more enlarged part under the trunk and on either side of the legs of the 'user.
En variante, le matelas présente une forme géométrique quelconque, notamment rectangulaire ou comportant des décrochements au niveau de la tête et du tronc afin de faciliter la fabrication industrielle en série du matelas.As a variant, the mattress has any geometrical shape, in particular rectangular or comprising recesses at the level of the head and the trunk in order to facilitate the industrial mass production of the mattress.
Par ailleurs également, et selon diverses variantes de réalisation d'un matelas de relaxation selon l'invention, les couches superposées du matelas peuvent être réalisées en matière plastique ou en caoutchouc notamment, et de préférence en matériaux plastique du genre mousse de polyéthylène ou équivalents.Also also, and according to various alternative embodiments of a relaxation mattress according to the invention, the superimposed layers of the mattress can be made of plastic or rubber in particular, and preferably of plastic materials such as polyethylene foam or the like. .
D'autres caractéristiques d'un matelas de relaxation établi conformément à l'invention apparaîtront encore à travers la description qui suit d'un exemple de réalisation donné à titre indicatif et non limitatif, en référence aux dessins annexés sur lesquels :
- La figure 1 est une vue de dessus d'un matelas de relaxation établi selon un premier mode de réalisation de l'invention, avec arrachement partiel.
- La figure 2 est une vue de coté et en coupe transversale, d'un détail du matelas considéré, illustrant notamment la structure en deux couches superposées de celui-ci.
- La figure 3 est une vue de dessus d'une autre variante de réalisation.
- Figure 1 is a top view of a relaxation mattress established according to a first embodiment of the invention, with partial cutaway.
- Figure 2 is a side view and in cross section, of a detail of the mattress considered, illustrating in particular the structure in two superposed layers thereof.
- Figure 3 is a top view of another alternative embodiment.
Dans l'exemple représenté sur la figure 1, le matelas selon l'invention désignée dans son ensemble sous la référence 1, présente un profil particulier adapté notamment à la morphologie de l'usager allongé sur ce matelas et flottant grâce à celui-ci entre deux eaux. La partie 2 plus étroite est destinée à servir d'appui à la tête de l'utilisateur, la partie 3 au tronc de celui-ci et la partie 4 au reste du corps, notamment aux jambes étendues reposant également de chaque côté du matelas. Avantageusement, celui-ci peut comporter une partie évidée 5 ménagée entre les zones du matelas supportant les jambes.In the example shown in Figure 1, the mattress according to the invention designated as a whole under the reference 1, has a particular profile adapted in particular to the morphology of the user lying on this mattress and floating thanks to it between two waters. The
Conformément à l'invention, le matelas 1 ci-dessus est réalisé au moyen de deux couches superposées respectivement 6 et 7, la couche supérieure 6 étant destinée à recevoir le corps de l'usager flottant sur le matelas, tandis que la couche 7 située sous la précédente est complètement. immergée. La couche 6 est formée d'une enveloppe étanche en caoutchouc ou en une matière synthétique appropriée, à l'intérieur de laquelle sont emprisonnées des bulles d'air 8 réparties uniformément dans toute l'étendue de cette couche, ces bulles d'air présentant un volume sensiblement identique de l'une à l'autre. Ces bulles sont séparées par des zones 9 où les deux parois de la couche 6 sont jointives, la fabrication d'une telle couche pouvant être facilement réalisée par tout procédé classique permettant une fois la couche remplie d'air, de préformer celle-ci, notamment à chaud pour la formation des bulles souhaitées.According to the invention, the mattress 1 above is produced by means of two superimposed layers respectively 6 and 7, the
La seconde couche 7.du matelas comporte, comme la précédente-, de-s bulles d'air 10 contiguës s'étendant sur toute la surface de la couche et séparées de l'une à l'autre par des zones étanches 11. Toutefois, dans ce second cas et selon une caractéristique essentielle de l'invention, les bulles d'air 10 présentent un volume qui peut être variable de l'une à l'autre et en particulier selon leur localisation sous le corps de l'usager, les bulles de volume plus important étant réparties dans les régions du matelas destinées à recevoir les parties du corps présentant la plus grande densité telles que la tête, la colonne vertébrale et d'une façon générale les éléments principaux du squelette de l'utilisateur.The second layer 7.of the mattress comprises, like the previous one,
Dans l'exemple illustré sur la figure 1, le matelas 1 présente une forme bien adaptée à celle du corps de l'usager, ce qui exige une fabrication particulière difficilement réalisable en grande série. Un tel matelas sera donc plus spécialement destiné à des usages médicaux pour flottaison en atmosphère et milieu contrôlés. Fn revanche, dans la variante selon la figure 3, le matelas 12 présente une forme géométrique simple et est plus directement approprié à une utilisation en piscine ou en bord de mer, pour jeux d'agrément.In the example illustrated in Figure 1, the mattress 1 has a shape well suited to that of the body of the user, which requires a particular manufacturing difficult to achieve in large series. Such a mattress will therefore be more especially intended for medical uses for flotation in a controlled atmosphere and environment. On the other hand, in the variant according to FIG. 3, the
Bien entendu, il résulte de ce qui précède que la forme particulière du matelas n'est en aucune façon limitative de la présente invention. De même, il va de soi que la structure des deux couches superposées pourrait subir de nombreuses variantes selon la nature des matériaux constituant l'enveloppe de ces couches et le procédé de fabrication dans celles-ci des bulles d'air- Egalement, on pourrait envisager d'autres structures où les deux couches superposées précédentes seraient associées à une ou deux couches supplémentaires de protection ou à une enveloppe extérieure entourant l'ensemble.Of course, it follows from the above that the particular shape of the mattress is in no way limitative of the present invention. Likewise, it goes without saying that the structure of the two superimposed layers could undergo many variants depending on the nature of the materials constituting the envelope of these layers and the process for manufacturing air bubbles therein. consider other structures where the two preceding superimposed layers would be associated with one or two additional layers of protection or with an external envelope surrounding the assembly.
Enfin, on pourrait sans sortir du cadre de l'invention donner aux bulles d'air constituant les couches superposées, des formes autres que sphériques, par exemple allongées, en croissant, en cube, en couronne, etc., afin d'épouser encore plus parfaitement toutes les morphologies des utilisateurs selon les zones d'appui sur le matelas.Finally, without departing from the scope of the invention, the air bubbles constituting the superimposed layers may be given forms other than spherical, for example elongated, crescent, cube, crown, etc., in order to marry further more perfectly all the morphologies of the users according to the support zones on the mattress.
