Abstract

The invention concerns a set of elements comprising a fluid whereof the assembly in grid network form a support for the human body such as a mattress or a bedspring. Each element consists of a block (1) containing a chamber, a vertical rod (2) and orifices enabling sealed communication with the chambers of adjacent elements. Each rod transmits a small part of the person's weight to the fluid contained in the chambers of the elements. Said force is passed on to the other rods through the channel of the chambers, so as to enable the pressure to be distributed without protrusions or recesses on the sleeper's body. The fact that the elements are nested enables a modular construction (the possibility of extending or reducing the support, the possibility of reusing the elements on other beds) and flexibility (the possibility of setting the elements on an adjustable bedspring).

Description

DISPOSITIF MODULAIRE DE SOUTIEN DU CORPS HUMAIN MODULAR HUMAN BODY SUPPORT DEVICE
La présente invention concerne un support pour le corps humain comprenant un ensemble d'éléments alignés, orientés parallèlement à la force en jeu, souvent verticalement pour la gravité, qui communiquent la pression exercée sur eux par une chambre à fluide rendue fonctionnellement commune par l'interconnexion entre les éléments, à l'image d'un ensemble de seringues interconnectées entre elles au moyen de tuyaux.The present invention relates to a support for the human body comprising a set of aligned elements, oriented parallel to the force at play, often vertically for gravity, which communicate the pressure exerted on them by a fluid chamber made functionally common by the interconnection between the elements, like a set of syringes interconnected by means of pipes.
Dans le but de trouver une solution aux inconvénients de confort des matelas traditionnels (latex, ressorts, mousse) ainsi que des matelas à eau, plusieurs tentatives de construction de lits comprenant un ensemble d'éléments verticaux alignés qui communiquent la pression exercée sur eux par une chambre à fluide commune ont été faites (U.S. Pat. N°5210889 et N° 5446933).In order to find a solution to the comfort disadvantages of traditional mattresses (latex, springs, foam) as well as water mattresses, several attempts to build beds comprising a set of aligned vertical elements which communicate the pressure exerted on them by a common fluid chamber were made (US Pat. No. 5210889 and No. 5446933).
Aucune ne répond complètement au besoin de facilité de montage, de modularité, de flexibilité, d'hygiène et d'écologie.None fully meets the need for ease of assembly, modularity, flexibility, hygiene and ecology.
Selon un mode préférentiel, la présente invention peut être décrite de la façon suivante :According to a preferred embodiment, the present invention can be described as follows:
Ensemble de vérins à fluide dont la disposition en réseau quadrillé forme un matelas, un sommier ou un siège. Chaque vérin est composé d'un bloc (1) enfermant une chambre, d'une tige verticale (2) et d'orifices qui permettent la communication avec les chambres des vérins voisins (voir Figures No. 1 et 2).Set of fluid cylinders, the grid layout of which forms a mattress, box spring or seat. Each cylinder is composed of a block (1) enclosing a chamber, a vertical rod (2) and orifices which allow communication with the chambers of neighboring cylinders (see Figures No. 1 and 2).
La disposition des vérins en réseau est due au besoin de rapprocher le plus possible les tiges qui supportent le poids de la personne.The arrangement of the cylinders in a network is due to the need to bring the rods that support the weight of the person as close as possible.
Chaque tige (2) transmet une petite partie du poids de la personne au fluide contenu dans les chambres des éléments. Le fluide est mis sous pression et est isolé par un joint étanche (3), ici lié à la tige (2). Cette force est retransmise aux autres tiges par le canal des chambres, de manière à permettre la répartition de la pression sans zones en pics ou creux sur le corps du dormeur ( voir Figure No. 10).Each rod (2) transmits a small part of the person's weight to the fluid contained in the chambers of the elements. The fluid is pressurized and is isolated by a tight seal (3), here linked to the rod (2). This force is retransmitted to the other rods by the channel of the chambers, so as to allow the distribution of the pressure without zones in peaks or hollow on the body of the sleeper (see Figure No. 10).
Les canaux de communication entre les chambres ou cavités sont constitués par les joints d'interconnexion. Ces joints sont conçus pour permettre un assemblage ou un désassemblage aisé des éléments constituant le réseau. Ils sont constitués par des protubérances s'emboîtant dans des encoches de forme complémentaire. Dans les encoches peuvent se trouver des joints étanches en matériau synthétique et des moyens de retenue axiale tel que des billes poussés par ressort, s'emboîtant dans des gouttières annulaires creusées dans les protubérances correspondantes, tel que dans les tuyauteries d'arrosage des jardiniers. Des terminateurs sont prévus pour fermer les canaux périphériques du réseaux s'ils ne sont pas reliés par des tuyaux à ceux de la rangé adjacente.The communication channels between the chambers or cavities are formed by the interconnection joints. These joints are designed to allow easy assembly or disassembly of the elements constituting the network. They consist of protrusions which fit into notches of complementary shape. In the notches can be sealed joints made of synthetic material and axial retaining means such as balls pushed by spring, fitting into annular gutters hollowed out in the corresponding protrusions, such as in the garden hoses. Terminators are provided to close the peripheral channels of the network if they are not connected by pipes to those of the adjacent row.
La pression initiale du fluide est réglée par une pompe (14) à l'aide d'une jauge (13) de façon à ce que l'individu s'enfonce au maximum dans le réseau de tiges, et minimise donc la compression épidermique.The initial fluid pressure is adjusted by a pump (14) using a gauge (13) so that the individual sinks as far as possible into the network of rods, and therefore minimizes epidermal compression.
la compression épidermique est encore diminuée par la présence d'un rembourrage (8) sur chaque tige (2) (voir Figures No. 1 et 7).the epidermal compression is further reduced by the presence of padding (8) on each rod (2) (see Figures No. 1 and 7).
En cas de charge brutale sur une des tiges (2), le ressort (5) illustré sur la Figure No. 1 amortit le choc du bas de la tige sur le fonds de la chambre, ce qui peut être aussi une sécurité.In the event of a sudden load on one of the rods (2), the spring (5) illustrated in Figure No. 1 absorbs the shock from the bottom of the rod on the bottom of the chamber, which can also be a safety measure.
La course de la tige vers le haut est stoppée par la présence d'axes (7). Sur la Figure No. 1 , la course de la tige (2) sous l'unique influence de la pression du fluide est illustrée par d1 alors qu'en d2 est ajoutée la force du ressort (5). La présente invention a les propriétés suivantes :The upward stroke of the rod is stopped by the presence of pins (7). In Figure No. 1, the stroke of the rod (2) under the sole influence of the fluid pressure is illustrated by d1 while in d2 is added the force of the spring (5). The present invention has the following properties:
1) Facilité de montage - Les éléments, ayant pour fonction de vérin, se montent comme indiqué sur la Figure No. 1 , soit par assemblage par les pressions du corps de l'élément (1 ) ou à l'aide de raccords (9), soit dans le cas d'une charnière, par assemblage au pôle ici avec des plaquettes (4) et en assurant la connexion des chambres, ici avec des tuyaux (6). La rigidité de la charnière est assurée par un axe (12). Sur la Figure No. 9, les bouchons (10) et capuchons (11 ) couvrent les orifices et les pressions des corps de l'élément (1 ) de telle manière à isoler le fluide contenu dans les chambres de l'extérieur. Les rembourrages (8) sont enfilés sur les extrémités des éléments (voir Figure No. 1).1) Ease of assembly - The elements, having the function of cylinder, are mounted as shown in Figure No. 1, either by assembly by the pressures of the body of the element (1) or using fittings (9 ), or in the case of a hinge, by assembly to the pole here with plates (4) and ensuring the connection of the chambers, here with pipes (6). The rigidity of the hinge is ensured by an axis (12). In Figure No. 9, the plugs (10) and caps (11) cover the orifices and pressures of the body of the element (1) so as to isolate the fluid contained in the chambers from the outside. The pads (8) are threaded over the ends of the elements (see Figure No. 1).
2) Modularité - Le matelas démonté est moins encombrant qu'un matelas traditionnel de la même taille, et peut ainsi être transporté à l'intérieur d'une voiture moyenne. Il permet d'être démonté et remonté pour constituer un lit de format différent pour autant que le nombre d'éléments à disposition en couvre la surface.2) Modularity - The disassembled mattress is less bulky than a traditional mattress of the same size, and can therefore be transported inside an average car. It makes it possible to be dismantled and reassembled to constitute a bed of different format as long as the number of elements available covers its surface.
3) Flexibilité - La conception du lit supporte également les sommiers ajustables. La Figure No. 11 illustre le profil du matelas pouvant évoluer sur un sommier ajustable si l'assemblage des éléments en charnière a été fait en parallèle à ceux du sommier ajustable. Comme indiqué sur la Figure No. 9, pour un meilleur confort lorsque le matelas est plié, les éléments sont montés en charnière à l'aide de plaquettes (4) et d'axes (12) sur les côtés extérieurs uniquement.3) Flexibility - The design of the bed also supports adjustable bed bases. Figure No. 11 illustrates the profile of the mattress that can evolve on an adjustable bed base if the hinged elements have been assembled in parallel with those of the adjustable bed base. As shown in Figure No. 9, for better comfort when the mattress is folded, the elements are hinged using plates (4) and pins (12) on the outer sides only.
4) Hygiène - Par le fait qu'il soit entièrement démontable, le lit peut être entièrement stérilisé. En outre, l'espace entre les tiges laisse circuler l'air en dessous du dormeur ce qui assure une meilleure respiration des parties du corps au contact du matelas.4) Hygiene - Because it is completely removable, the bed can be fully sterilized. In addition, the space between the rods allows air to circulate below the sleeper which ensures better breathing of the body parts in contact with the mattress.
5) Ecologique - Le choix des matériaux lui permet un taux de recyclage élevé. 5) Ecological - The choice of materials allows it a high recycling rate.
