Abstract
Description
La présente invention concerne des perfectionnements apportés au matelas décrit au brevet principal. The present invention relates to improvements made to the mattress described in the main patent.
Le brevet principal se rapporte à un matelas alvéolé en mousse qui comprend, suivant sa longueur, plusieurs zones dans lesquelles la section totale des alvéoles pour une aire donnée de la surface du matelas est différente de l'une desdites zones à une zone voisine. The main patent relates to a cellular foam mattress which comprises, along its length, several zones in which the total section of the cells for a given area of the surface of the mattress is different from one of said zones to a neighboring zone.
L'invention concerne un matelas tel que défini cidessus qui présente au moins une partie en forme de grille dans laquelle les alvéoles sont constitués par des trous traversant la grille de part en part. The invention relates to a mattress as defined above which has at least one part in the form of a grid in which the cells are formed by holes passing through the grid right through.
D'autres caractéris-tiques et avantages de l'invention ressortiront de la description qui va suivre d'un mode de réalisation donné uniquement à titre d'exemple et illustré par le dessin annexé sur lequel la Fig. unique est une vue partielle en coupe d'un matelas suivant l'invention. Other characteristics and advantages of the invention will emerge from the description which follows of an embodiment given solely by way of example and illustrated by the appended drawing in which FIG. single is a partial sectional view of a mattress according to the invention.
En se reportant à la Fig. unique-, le matelas 1 suivant l'invention comprend une âme alvéolée 2 en mousse de latex recouverte sur ses faces opposées de couches 3 et 4 en mousse de polyéther dépourvues d'alvéoles. L'âme 2 est constituée d'un bloc de mousse de latex en forme de paral lélépipède rectangle dans lequel sont ménagés un grand nombre d'alvéoles 5 dont la section est différente d'une zone à. l'autre du matelas de marnière à. supporter le corps d'un individu dans une position naturelle. Referring to FIG. single-, the mattress 1 according to the invention comprises a honeycomb core 2 of latex foam covered on its opposite faces with layers 3 and 4 of polyether foam devoid of cells. The core 2 consists of a block of latex foam in the form of a rectangular rectangular elepiped in which a large number of cells 5 are formed, the section of which is different from one area to another. the other from the hinge mattress to. support an individual's body in a natural position.
Ce matelas. I est en tout point identique à celui des
Fig. 1 et 2 du brevet principal à ceci près que les alvéoles 5 sont constitués par des trous traversant l'amie 2 de part en part de telle sorte que celle-ci présente une structure en forme de grille. Cet agencement a entre autres pour avantage d'offrir une réaction égale sur ses deux faces.This mattress. I is identical in all respects to that of
Fig. 1 and 2 of the main patent except that the cells 5 are formed by holes passing through the friend 2 right through so that it has a grid-like structure. One advantage of this arrangement is that it offers an equal reaction on both sides.
Bien entendu, l'invention n'est pas limitée au mode de réalisation décrit ci-des sus et la grille 2 pourrait être réalisée avec n' importe quelle autre répartition appropriée des trous traversant 5, telle-que celle de la
Fig. 5 du brevet principal, permettant de supporter le corps d'un individu dans une position naturelle. Comme indiqué dans le brevet principal, la variation d'une zone à l'autre de la section totale des alvéoles pour une aire donnée de la surface du matelas peut être obtenue également en réalisant des alvéoles ou trous 5 à section individuelle constante disposés avec un pas plus petit dans les zones souples que dans les zones rigides.Of course, the invention is not limited to the embodiment described above and the grid 2 could be produced with any other appropriate distribution of the through holes 5, such as that of the
Fig. 5 of the main patent, making it possible to support the body of an individual in a natural position. As indicated in the main patent, the variation from one zone to another of the total section of the cells for a given area of the surface of the mattress can also be obtained by producing cells or holes 5 with constant individual section arranged with a not smaller in flexible areas than in rigid areas.
D'autre part, les couches 3 et 4 peuvent etre réalisées en n'importe quelle matière appropriée autre que de la mousse de polyéther et la présence de celles-ci n'est pas indiepensable, la grille 2 pouvant être utilisée seule ou avec une seule couche. On the other hand, layers 3 and 4 can be made of any suitable material other than polyether foam and the presence of these is not essential, the grid 2 can be used alone or with a single layer.
D'une façon générale, toutes les modifications ou variantes envisagées dans le brevet principal peuvent s'appliquer au matelas suivant ltinvention. In general, all the modifications or variants envisaged in the main patent can apply to the mattress according to the invention.
