Abstract

Support for use as a mattress (9), cushion or filling comprising a base for receiving tenons (3) with pads (2) which together form removable units (4) made from the same materials (non-rigid cellular foam). The units are fastened onto the base by the tenon (3) and mortise (5) method.

Description

"Support en mousse; s 'appliquant à la conception de matelas, coussins, rembourrages; à modules amovibles " La présente invention a pour objet un support pouvant servir de matelas, coussin ou rembourrage, constitué d'une embase sur une face de laquelle sont disposés des plots qui sont au contact d'un individu allongé dans le cas d'un matelas. Ce support peut être employé à un usage médical, tel que les matelas et coussins anti-escarres et supports de protection lombaire. "Foam support; applying to the design of mattresses, cushions, padding; with removable modules" The present invention relates to a support that can serve as a mattress, cushion or padding, consisting of a base on one side of which are arranged pads which are in contact with an elongated individual in the case of a mattress. This support can be used for medical use, such as anti-decubitus mattresses and cushions and lumbar protection supports.
Ce type de support est déjà connu dans son principe par les matelas de mousse en forme de moule à gaufre dits gaufriers, ou les matelas tels que décrits dans les demandes : Fr 2.539.297 et Fr 2.592.779. Mais ces divers supports présentent les inconvénients respectifs majeurs suivants :Le premier en mousse homogène ne peut s'adapter facilement à la morphologie du malade, le second nécessite des opérations de collage et de découpe longues et coûteuses pour sa fabrication, le troisième nécessite pour assembler les modules; une grille qui par ses qualités mécaniques, peut nuire à l'effet bénéfique recherché.This type of support is already known in principle by foam mattresses in the form of waffle molds called waffle irons, or mattresses as described in the applications: Fr 2.539.297 and Fr 2.592.779. However, these various supports have the following major drawbacks: The first of homogeneous foam cannot easily adapt to the patient's morphology, the second requires long and costly gluing and cutting operations for its manufacture, the third requires to assemble modules; a grid which by its mechanical qualities can harm the desired beneficial effect.
La présente invention se propose d'apporter des solutions permettant de remédier aux inconvénients des procédés connus anté- rieurement.The present invention proposes to provide solutions which make it possible to remedy the drawbacks of the methods known previously.
En conséquence cette invention; a pour objet la conception de matelas, coussins, rembourrages, en mousse souple; caractérisée en ce qu'on réalise un support tel que matelas, coussins, rembourrage comprenant une embase de fixation, pour des tenons supportant des plots formant des modules amovibles, de mêmes matériaux (mousse alvéolaire souple); le mode de fixation des modules sur l'embase étant réalisé selon le principe du tenon et de la mortaise.Consequently this invention; relates to the design of mattresses, cushions, padding, in flexible foam; characterized in that a support is produced such as mattress, cushions, padding comprising a fixing base, for studs supporting studs forming removable modules, of the same materials (flexible cellular foam); the method of fixing the modules to the base being carried out according to the tenon and mortise principle.
D'autres caractéristiques et avantages de la présente inven¬ tion ressortiront de la description faite ci-après en référence aux dessins annexés qui en illustrent un exemple de réalisation dépourvu de tout caractère limitatif, sur les figures :Other characteristics and advantages of the present inven¬ tion will emerge from the description given below with reference to the accompanying drawings which illustrate an embodiment thereof devoid of any limiting character, in the figures:
- La figure 1 est une vue en perspective d'un matelas obtenu par la mise en oeuvre de l'invention.- Figure 1 is a perspective view of a mattress obtained by the implementation of the invention.
- La figure 2 est une vue partielle en perspective d'une embase nue sans module.- Figure 2 is a partial perspective view of a bare base without module.
- La figure 3 est une vue en coupe de modules amovibles.- Figure 3 is a sectional view of removable modules.
- La figure 4 est une vue partielle en coupe d'une embase au niveau de deux formes de mortaises différentes.- Figure 4 is a partial sectional view of a base at two different forms of mortises.
- La figure 5 est une vue de différentes formes de section de tenons. - La figure 6 est une vue partielle en coupe du support, c'est à dire de modules fixés sur une embase.- Figure 5 is a view of different shapes of stud section. - Figure 6 is a partial sectional view of the support, that is to say of modules fixed to a base.
- La figure 7 est une vue partielle du support en coupe de modules fixés sur une embase, la hauteur des tenons étant inférieure à l'épaisseur de l'embase.- Figure 7 is a partial view of the sectional support of modules attached to a base, the height of the pins being less than the thickness of the base.
Selon un exemple préféré de réalisation d'un matelas 9, se reporter à la figure 1 sur laquelle on aperçoit un matelas 9 obtenu selon la mise en oeuvre de l'invention posée sur un bâti de lit 10; ainsi des plots en relief 2 émergent de l'embase 1 dans laquelle est fixé le tenon 3 qui avec le plot 2 forme le module 4.Le malade allongé repose sur les plots 2 solidaires de l'embase 1.According to a preferred embodiment of a mattress 9, refer to FIG. 1 on which we can see a mattress 9 obtained according to the implementation of the invention placed on a bed frame 10; thus raised studs 2 emerge from the base 1 in which is fixed the post 3 which with the stud 2 forms the module 4. The elongated patient rests on the pads 2 secured to the base 1.
Les embases 1 et les modules 4 peuvent être réalisés en mousse alvéolaire souple structurée par découpage et de préférence par mou¬ lage de la mousse (fig.2, fig.3). De façon à éviter un désassemblage intempestif de la fixation mortaise tenon, la fixation peut être réalisée en queue d'aronde 6 (fig.4 et fig.6) .The bases 1 and the modules 4 can be made of flexible cellular foam structured by cutting and preferably by molding of the foam (FIG. 2, FIG. 3). In order to avoid untimely disassembly of the tenon mortise fixing, the fixing can be carried out in dovetail 6 (fig.4 and fig.6).
Les mortaises 5 peuvent avoir des sections différentes, par exemple carrée sur la figure 2. En correspondance à la forme de la section des mortaises 5 on préfère les sections de tenons 3 de forme carrée, polygonale, ovale, à des sections de forme cylindrique (fig. 5), de façon à empêcher la rotation du module sur son axe 7.The mortises 5 can have different sections, for example square in FIG. 2. In correspondence with the shape of the mortise section 5, the tenon sections 3 of square, polygonal, oval shape are preferred to sections of cylindrical shape ( fig. 5), so as to prevent rotation of the module on its axis 7.
Mais si la forme de la fixation permet la rotation du tenon 3 dans la mortaise 5 autour de l'axe 7, on peut bloquer cette rotation en utilisant des tenons 3 de volume supérieur à celui de la mortaise 5.But if the shape of the fixing allows the rotation of the tenon 3 in the mortise 5 around the axis 7, this rotation can be blocked by using tenons 3 of volume greater than that of the mortise 5.
La hauteur des plots 2 émergeant de 1'embase 1 peut varier de façon à s'adapter à la morphologie du malade. La hauteur des tenons 3 par rapport à l'épaisseur de l'embase peut varier, de préférence en diminution; de façon que par un retrait artificiel de matière 8 on puisse donner des réactions différentes à la compression de l'embase 1 solidaire des plots 2 sur lesquels est allongé le malade. La densité oupoids spécifique de la mousse des modules 4 peut être différente de celle de l'embase 1; la densité de différents modules 4 entre eux, sur le même matelas , peut aussi varier de façon à accroître l'effet d'adaptation à la morphologie du patient.The height of the studs 2 emerging from the base 1 can vary so as to adapt to the morphology of the patient. The height of the pins 3 relative to the thickness of the base can vary, preferably decreasing; so that by an artificial withdrawal of material 8 one can give different reactions to the compression of the base 1 secured to the pads 2 on which the patient is lying. The specific density or weight of the foam of the modules 4 may be different from that of the base 1; the density of different modules 4 between them, on the same mattress, can also vary so as to increase the effect of adaptation to the morphology of the patient.
Selon 1'invention, la mise en oeuvre de ces supports peut donc s'appliquer à la réalisation de matelas anti-escarres; mais aussiAccording to the invention, the implementation of these supports can therefore be applied to the production of anti-decubitus mattresses; but also
