Description

L'invention concerne un lit dans lequel on réalise un flux d'air en circuit fermé pour améliorer le bien-être du corps étendu.The invention relates to a bed in which an air flow is carried out in a closed circuit. to improve the well-being of the extended body.

Dans l'état actuel de la technique, on a cherché à améliorer l'état de bien-être du corps pendant le sommeil par l'utilisation de matelas de différents types, à ressorts, en latex, orthopédiques et analogues et par l'emploi de treillis à lattes qui permettent au corps, lorsqu'il est étendu, de prendre une position « naturelle », en évitant la déformation de la colonne vertébrale ou la compression des vaisseaux capillaires, qui fait obstacle à la circulation sanguine.In the current state of the art, attempts have been made to improve the state of well-being of the body during sleep by the use of mattresses of different types, with springs, in latex, orthopedic and similar and by the use of slatted mesh which allow the body, when extended, to take a "natural" position, avoiding the deformation of the spine or compression of the capillaries, which obstructs blood circulation.

En particulier, dans les demandes de brevets n° VI98A000232 et n° VI99A000033, de la même demanderesse, on décrit des treillis pour le support du matelas dans lesquels, grâce à l'emploi de supports élastiques équilibrés, les lattes qui composent le plan du lit sont capables de se déplacer aussi bien dans la direction horizontale que dans la direction verticale et, en outre, sont soumises au même effort indépendamment de leur déformation, plus ou moins notable, de sorte qu'elles engendreront sur le corps étendu une poussée de valeur uniforme, typique du corps qui flotte.In particular, in patent applications No. VI98A000232 and No. VI99A000033, from the same applicant, we describe lattices for supporting the mattresses in which, thanks to the use of balanced elastic supports, the slats which make up the bed plane are able to move as well in the direction horizontal as in the vertical direction and, moreover, are subjected to the same force regardless of their deformation, more or less noticeable, so that they will generate on the extended body a thrust of uniform value, typical of the body which fleet.

Grâce à l'emploi de ces types de treillis à lattes équilibrées, le plan du lit prend une flexibilité qui lui permet de se déformer en mouvement anatomique, en se conformant au profil du corps étendu, de manière à assurer les fonctions qui, normalement, sont assurées par le matelas.Thanks to the use of these types of lattice with balanced slats, the bed plan takes flexibility that allows it to deform in anatomical movement, conforming to the profile of the extended body, so as to ensure the functions which, normally are provided by the mattress.

Dans un tel cas, le matelas se réduit à une natte de quelques centimètres, en facilitant donc l'application innovante qui réalise le but de la présente invention, qui est d'augmenter encore le bien-être du repos en éliminant l'inconfort provoqué par les variations du microclimat, telles que la température excessivement élevée ou abaissée, le degré d'humidité excessif ou trop faible, qui s'établissent entre la couverture et le matelas.In such a case, the mattress is reduced to a mat of a few centimeters, therefore facilitating the innovative application which achieves the object of the present invention, which is to further increase the well-being of rest by eliminating the discomfort caused by variations in the microclimate, such as excessively high or low temperatures, the excessive or too low humidity level, which is established between the cover and the mattress.

Dans le document US-A-4939804 est décrit un lit à flux d'air où on met en recirculation l'air qui entoure le corps étendu et recouvert, de manière que les valeurs de la température et de l'humidité soient maintenues à un niveau optimal, en évitant ainsi au corps lui-même d'assurer une autorégulation continue, qui constitue la principale condition d'inconfort pendant le sommeil.In document US-A-4939804, an air flow bed is described where the recirculates the air surrounding the extended and covered body, so that the values of temperature and humidity are kept at an optimal level, thus avoiding to the body itself to ensure continuous self-regulation, which is the main condition of discomfort during sleep.

But de l'invention est celui d'améliorer les caractéristiques du susdit lit pour garantir à l'usager un confort encore meilleur.Aim of the invention is to improve the characteristics of the above bed to guarantee the user even better comfort.

Cela est obtenu, selon l'invention, en prévoiant que l'air contenu dans la partie centrale de l'espace intermédiaire délimité par la couverture bordée sur le matelas, celle située dans la zone du corps étendu, soit tout d'abord aspiré vers l'extérieur, à travers des trous pratiqués en position centrale dans le matelas, et ensuite renvoyé à l'intérieur dudit espace intermédiaire, à travers des trous pratiqués dans les parties latérales du matelas.This is obtained, according to the invention, by providing that the air contained in the part central of the intermediate space delimited by the cover bordered on the mattress, that located in the extended body area, first sucked outward through holes made centrally in the mattress, and then returned inside said intermediate space, through holes made in the lateral parts of the mattress.

On réalise de cette façon une circulation d'air entre les parties latérales et la zone centrale de la chambre à air définie par le matelas et par la couverture, de sorte que le corps, léché par un léger flux d'air tempéré, se maintient dans des conditions de bien-être.This creates an air circulation between the side parts and the area air chamber center defined by the mattress and the blanket, so that the body, licked by a gentle flow of temperate air, maintains itself in conditions of well-being.

Sous l'aspect de la construction, il est prévu essentiellement deux chambres intercommunicantes disposées au-dessous du matelas, convenablement perforé ; la première chambre, placée dans la région de la partie centrale du plan du lit, est munie d'un aspirateur à faible hauteur d'aspiration, qui assure l'aspiration de l'air qui entoure le corps au repos, tandis que la deuxième chambre, placée le long des deux bords longitudinaux du matelas, assure le refoulement en retour de l'air précédemment aspiré dans l'espace intermédiaire. In terms of construction, there are basically two rooms intercommunicants arranged below the mattress, suitably perforated; the first bedroom, placed in the region of the central part of the bed plan, is provided a vacuum cleaner with low suction height, which ensures the suction of the air surrounding the body at rest, while the second chamber, placed along the two edges longitudinal of the mattress, provides backflow of previously sucked air in the intermediate space.

Dans le conduit de liaison entre les chambres, la chambre centrale et les deux chambres latérales, sont avantageusement intercalés des filtres, des humidificateurs et des thermorégulateurs qui améliorent les caractéristiques de l'air en recirculation, en les adaptant aux conditions ambiantes extérieures ou aux exigences de la personne qui repose.In the connecting duct between the chambers, the central chamber and the two side chambers, are advantageously interposed with filters, humidifiers and thermoregulators which improve the characteristics of recirculating air by adapting to external ambient conditions or to the requirements of the person rests.

Afin de rendre plus claire la compréhension de la structure et des caractéristiques de la présente invention, on en décrira maintenant une forme particulière de réalisation, donnée à seul titre d'exemple illustratif et non limitatif, en se reportant à la planche de dessin annexée, où :

  • la figure 1 représente une vue transversale en élévation et en coupe, du lit selon l'invention ;
  • la figure 2 représente une vue en perspective, partiellement en coupe, du lit selon l'invention.
    • In order to make the understanding of the structure and the characteristics of the present invention clearer, a particular embodiment will now be described, given solely by way of illustrative and nonlimiting example, with reference to the attached drawing board, or :
  • FIG. 1 represents a transverse view in elevation and in section, of the bed according to the invention;
  • 2 shows a perspective view, partially in section, of the bed according to the invention.

    • Comme on peut le voir sur les figures, au-dessous du matelas 1, de faible épaisseur et supporté par les lattes 2, sont ménagées une chambre centrale 3 et deux chambres latérales 4' et 4" qui s'étendent longitudinalement sur toute la longueur du matelas, sauf dans la zone d'appui de l'oreiller.As can be seen in the figures, below the mattress 1, of low thickness and supported by the slats 2, are provided a central chamber 3 and two lateral chambers 4 'and 4 "which extend longitudinally over the entire length of the mattress, except in the pillow support area.

    Lesdites chambres seront mises en communication, par l'intermédiaire d'une pluralité de trous centraux 5 et latéraux 6' et 6", avec l'espace intermédiaire 7 délimité par la couverture 8 qui recouvre le corps 9 et qui est bordée sur les côtés du matelas 1.Said chambers will be put in communication, via a plurality of central 5 and lateral 6 'and 6 "holes, with the intermediate space 7 delimited by the cover 8 which covers the body 9 and which is bordered on the sides of the mattress 1.

    Comme on peut le voir sur la figure 1, sur la chambre centrale 3, est monté un aspirateur 10 qui aspire, à travers la pluralité de trous 5 pratiqués dans la partie centrale du matelas 1, l'air qui occupe la partie centrale de l'espace intermédiaire, pratiquement celle qui est en contact avec le corps 9 au repos. As can be seen in Figure 1, on the central chamber 3, is mounted a vacuum cleaner 10 which sucks through the plurality of holes 5 made in the central part of the mattress 1, the air which occupies the central part of the intermediate space, practically that which is in contact with the body 9 at rest.

    L'air aspiré est envoyé, par les conduits 11' et 11'', aux deux chambres latérales 4' et 4" et, de là, il revient dans l'espace intermédiaire 7 à travers la pluralité de trous latéraux 6' et 6".The sucked air is sent, through the ducts 11 'and 11' ', to the two lateral chambers 4 'and 4 "and from there it returns to the intermediate space 7 through the plurality of holes side 6 'and 6 ".

    De cette façon, on engendre un flux d'air continu 12 qui lèche le corps 9 en donnant à l'utilisateur une sensation de bien-être.In this way, a continuous air flow 12 is generated which licks the body 9 in giving the user a feeling of well-being.

    Pour améliorer cet état de bien-être, on a intercalé dans les conduits de refoulement de l'air des appareils 13 qui améliorent la qualité de l'air en recirculation, en en réglant la température, le degré d'humidité, ou en jouant le rôle d'un filtre purificateur.To improve this state of well-being, we inserted in the conduits of delivery of air from devices 13 which improve the quality of recirculating air, by adjusting the temperature, the humidity level, or by acting as a filter purifier.

    Il est en outre prévu la possibilité que le flux d'air conditionne le plan du lit même lorsque la couverture est entièrement appliquée sur le matelas, de sorte que, même en l'absence de l'espace intermédiaire 7, on peut avoir la même recirculation d'air ou le même flux d'air.The possibility is also provided that the air flow conditions the bed surface even when the blanket is fully applied to the mattress, so that, even in the absence of the intermediate space 7, one can have the same air recirculation or the same air flow.

    Dans ce but, il est prévu des microcanaux 14 formés sur la surface supérieure du matelas 1, qui relient des trous latéraux 6 à des trous centraux 5, lesdits microcanaux étant ouverts en haut de manière que le flux d'air se répande entre la couverture et le matelas ou entre les draps ( voir figure 2).For this purpose, there are provided microchannels 14 formed on the upper surface of the mattress 1, which connect lateral holes 6 to central holes 5, said microchannels being open at the top so that the air flow is spread between the cover and the mattress or between sheets (see Figure 2).

    Finalement, il est prévu que le matelas, qui fait partie intégrante du système de recirculation de l'air en circuit fermé, soit perforé dans la direction verticale dans deux ou plus de deux zones distinctes l'une de l'autre pour assurer la continuité du flux avec les chambres sous-jacentes séparées, et qu'il soit d'une épaisseur minime afin d'éviter que lesdits trous de passage de l'air se bouchent avec la déformation du matelas, et aussi afin de profiter au maximum de l'élasticité des lattes.Finally, it is planned that the mattress, which is an integral part of the air recirculation in a closed circuit, either perforated in the vertical direction in two or more than two separate areas from each other to ensure continuity of flow with separate underlying chambers, and be of minimal thickness to avoid that said air passage holes become blocked with the deformation of the mattress, and also to make the most of the elasticity of the slats.

    Des formes de réalisation différentes de celle qui est illustrée sont évidemment possibles, comme l'application sur des treillis qui ne sont pas à lattes ou encore il est possible que le flux d'air ait une circulation opposée à celle décrite tout en conservant la caractéristique de nouveauté de l'invention qui prévoit de produire un flux d'air qui traverse le matelas dans les deux sens.Different embodiments from the one illustrated are obviously possible, such as application on trellises that are not slatted or it is possible that the air flow has a flow opposite to that described while maintaining the novelty characteristic of the invention which provides for producing an air flow which cross the mattress in both directions.
