Description

Cette invention concerne une installation permettant de soutenir les lattes d'un sommier disposé par rapport au châssis d'un lit, chaque latte étant soutenue par une tige qui se trouve directement ou indirectement sous l'influence d'un élément actionné hydrauliquement ou pneumatiquement, lequel élément peut être déplacé à l'intérieur d'une chambre, toutes les chambres étant reliées entre elles selon le principe des vases communicants.This invention relates to an installation making it possible to support the slats of a box spring disposed with respect to the frame of a bed, each slat being supported by a rod which is directly or indirectly under the influence of an element actuated hydraulically or pneumatically, which element can be moved inside a room, all the rooms being interconnected according to the principle of communicating vessels.

Un exemple d'une forme de réalisation de l'espèce est constitué par le brevet belge 806.241, de même que par la demande de brevet PCT WO 89/01749 ainsi que par le brevet U.K. 2.178.307. Suivant ces documents, plusieurs cylindres ou chambres remplissant une fonction technique équivalente sont disposés des deux côtés du sommier à lattes et ces cylindres ou leurs éqivalents sont reliés entre eux par une conduite de telle façon que les divers cylindres ou chambres fonctionnent comme des vases communicants.An example of an embodiment of the present case is constituted by the Belgian patent 806,241, as well as by the PCT patent application WO 89/01749 as well as by the patent U.K. 2,178,307. According to these documents, several cylinders or chambers fulfilling an equivalent technical function are arranged on both sides of the slatted base and these cylinders or their equivalents are connected to one another by a pipe so that the various cylinders or chambers function as communicating vessels.

Dans une forme de réalisation de l'espèce visée, la partie centrale du sommier à lattes s'enfoncera complètement jusqu'au point le plus bas lorsque l'utilisateur se couche sur celui-ci et celà indépendamment de sa position. Ceci est dû au fait que le corps est le plus lourd en sa partie centrale.In one embodiment of the target species, the central part of the slatted base will sink completely to the lowest point when the user lies on it and this regardless of its position. This is due to the fact that the body is the heaviest in its central part.

L'invention a pour but de remédier à cet inconvénient et à divers autres et de prescrire une installation qui améliore sensiblement le support élastique d'un tel sommier à lattes.The invention aims to remedy this drawback and various others and to prescribe an installation which substantially improves the elastic support of such a slatted base.

Pour réaliser ceci conformément à l'invention, au moins une partie des éléments susdits, qui sont chacun déplacés sous l'action de la pression exercée, sont soumis à l'action d'un ressort de contre-pression.To achieve this in accordance with the invention, at least a portion of the aforementioned elements, which are each moved under the action of the pressure exerted, are subjected to the action of a counter-pressure spring.

Dans une première forme de réalisation possible, l'élément actionné hydrauliquement ou pneumatiquement consiste en un piston dont la bielle correspond à la tige précitée.In a first possible embodiment, the hydraulically or pneumatically actuated element consists of a piston whose connecting rod corresponds to the aforementioned rod.

Dans une autre forme de réalisation possible, l'élément déplaçable hydrauliquement ou pneumatiquement est une membrane à laquelle la biellette précitée est reliée.In another possible embodiment, the hydraulically or pneumatically movable element is a membrane to which the aforementioned link is connected.

Dans une forme de réalisation remarquable appliquée de préférence, l'élément déplaçable précité est une membrane enroulable qui agit sur la tige guidée dans la chambre précitée.In a remarkable embodiment preferably applied, the above-mentioned movable element is a roll-up membrane which acts on the rod guided in the aforementioned chamber.

En se référant en premier lieu aux figures 1 et 2, on constate que le mouvement ascendant et descendant d'un sommier à lattes est causé par la disposition d'un poids 1 sur ces lattes. Ceci provoque une circulation interne du liquide dans les cylindres ou chambres qui sera décrite plus loin en détail. En raison du fait que le liquide n'est pas compressible, un déplacement du liquide doit avoir lieu. Si celui-ci n'a pas lieu, aucun déplacement n'est possible. Au passage, il doit être souligné que dans la description et les revendications, le terme "chambre" sera utilisé parce que ceci désigne un support qui peut aussi bien être hydraulique que pneumatique.Referring first to Figures 1 and 2, we see that the upward and downward movement of a slatted base is caused by the provision of a weight 1 on these slats. This causes an internal circulation of the liquid in the cylinders or chambers which will be described later in detail. Due to the fact that the liquid is not compressible, a displacement of the liquid must take place. If this does not take place, no movement is possible. Incidentally, it should be pointed out that in the description and the claims, the term "chamber" will be used because this designates a support which can be both hydraulic and pneumatic.

Le déplacement envisagé des lattes qui forment le sommier à lattes est freiné en diaphragmant, de manière connue en soi, les orifices de sortie des chambres ou cylindres. Par le mouvement linéaire d'un certain nombre de lattes appartenant au sommier à lattes, tel que représenté à la figure 1, une pression vers le bas est créée de telle sorte que les lattes sur lesquelles une pression est exercée se trouvent complètement dans leur position la plus basse. Les autres lattes qui ne supportent pas de poids ni de pression viennent se positionner dans la position la plus élevée. Cette situation se développe dans la supposition que, pour une position de repos neutre, toutes les chambres sont à moitié remplies.The envisaged displacement of the slats which form the slatted base is slowed down by diaphragming, in a manner known per se, the orifices of exit from chambers or cylinders. By the linear movement of a number of slats belonging to the slatted base, as shown in Figure 1, a downward pressure is created so that the slats on which pressure is exerted are completely in their position the lowest. The other slats that do not support weight or pressure are positioned in the highest position. This situation develops on the assumption that, for a neutral rest position, all the rooms are half full.

Une situation analogue, dérivée de cette situation théorique, est représentée à la figure 2. A la figure 2, la partie la plus lourde du corps 3 repose au milieu du sommier à lattes, milieu considéré dans le sens de la longueur. Dans cette figure schématique, le sommier à lattes est représenté par la référence 2. La figure 2 est une représentation d'un sommier à lattes dans lequel toutes les lattes 4 s'appuie sur des biellettes 5 qui sont soit complètement enfoncées là où le corps offre son poids le plus lourd, soit se trouvent dans leur position la plus élevée, là où aucune pression ou une pression insignifiante est exercée sur les lattes.A similar situation, derived from this theoretical situation, is represented in FIG. 2. In FIG. 2, the heaviest part of the body 3 rests in the middle of the slatted base, the medium considered lengthwise. In this schematic figure, the slatted base is represented by the reference 2. Figure 2 is a representation of a slatted base in which all the slats 4 rests on rods 5 which are either fully inserted where the body offers its heaviest weight, either found in their highest position, where no pressure or insignificant pressure is exerted on the slats.

A la figure 3 est illustré schématiquement l'exemple du cas dans lequel le corps 3 de l'utilisateur s'appuie sur des lattes 4 qui s'appuient elles- mêmes sur des biellettes 5 qui sont soumises à l'action d'un ressort de contre-pression selon l'une ou l'autre des dispositions décrites ci-après. Il se crée ici une répartition idéale des lattes et il existe une position intermédiaire bien visible de ces lattes entre une position dans laquelle elles auraient normalement dû être complètement enfoncées et une seconde position dans laquelle elles auraient pu se trouver dans la position la plus élevée. La manière dont peut être inséré un ressort de contre-pression dans un sommier à lattes selon l'invention est décrite en se référant à un grand nombre d'exemples.In Figure 3 is illustrated schematically the example of the case in which the body 3 of the user is supported on slats 4 which are themselves supported on rods 5 which are subjected to the action of a spring back pressure according to one or other of the provisions described below. An ideal distribution of the slats is created here and there is a clearly visible intermediate position of these slats between a position in which they normally should have been fully inserted and a second position in which they could have been in the highest position. The way in which a counterpressure spring can be inserted into a slatted base according to the invention is described with reference to a large number of examples.

Selon la figure 4, il est prévu à la base de la chambre 6 un espace 7 qui est mis en communication à travers un étranglement 8 avec une conduite 9 qui relie toutes les chambres 7 d'une série. Une membrane 10 délimite cet espace 7 à sa partie supérieure. Sur la membrane 10 est fixée une petite tige 11 présentant un point d'articulation en 12 destiné à un levier 13 qui est relié à charnière en 14 avec la biellette 5. Cette biellette traverse l'élément 15. Entre cet élément 15 et une goupille 17 faisant saillie hors de la biellette 5, est disposé un ressort à pression 16. Ce ressort à pression 16 constitue le ressort de contre-pression selon l'invention. Aux figures 4 à 7, le point de rotation du levier 13 est indiqué par la référence 12'.According to Figure 4, there is provided at the base of the chamber 6 a space 7 which is put in communication through a throttle 8 with a pipe 9 which connects all the chambers 7 of a series. A membrane 10 delimits this space 7 at its upper part. On the membrane 10 is fixed a small rod 11 having an articulation point at 12 intended for a lever 13 which is connected to the hinge at 14 with the link 5. This link crosses the element 15. Between this element 15 and a pin 17 protruding from the link 5, a pressure spring 16 is arranged. This pressure spring 16 constitutes the counter-pressure spring according to the invention. In Figures 4 to 7, the point of rotation of the lever 13 is indicated by the reference 12 '.

A la figure 5, le ressort de contre-pression 18 est un ressort de traction qui peut être tendu entre une latte 4 et une goupille 19 faisant saillie à la base hors de l'élément 15.In FIG. 5, the counter-pressure spring 18 is a tension spring which can be tensioned between a batten 4 and a pin 19 projecting at the base from the element 15.

Dans la forme d'exécution selon la figure 6, on fait également usage d'un ressort de contre-pression se présentant sous la forme d'un ressort de traction 20 qui est mis sous tension entre une latte 4 et l'élément 15. A sa base, le ressort de traction 20, qui présente à cet effet des orifices 22, est fixé sur un téton 21 qui fait lui-même partie de l'élément 15.In the embodiment according to FIG. 6, use is also made of a counter-pressure spring in the form of a tension spring 20 which is tensioned between a batten 4 and the element 15. At its base, the tension spring 20, which has orifices 22 for this purpose, is fixed to a stud 21 which itself is part of the element 15.

Selon la figure 7, on fait usage, en tant que ressort de contre-pression 23, d'un ressort à pression disposé dans une cavité 7 de la chambre 6.According to FIG. 7, use is made, as a counter-pressure spring 23, of a pressure spring disposed in a cavity 7 of the chamber 6.

Selon les figures 8 à 11 incluse, on applique, dans chacune des chambres 6, une membrane enroulée 24. Les membranes enroulées ont une structure fort souple de telle sorte qu'une partie de la membrane enroulée s'enroule et se déroule entre la paroi intérieure de la chambre 6 et la paroi extérieure d'un piston 25 qui est fixé à la base de la biellette 5. Le piston 25 est guidé par rapport à la chambre 6 grâce à une petite partie cylindrique 26 qui fait partie de la chambre 6, à la partie supérieure et à l'intérieur de celle-ci.According to FIGS. 8 to 11 inclusive, a rolled membrane 24 is applied in each of the chambers 6. The rolled membranes have a very flexible structure so that part of the rolled membrane rolls up and takes place between the wall inside of the chamber 6 and the outer wall of a piston 25 which is fixed to the base of the link 5. The piston 25 is guided relative to the chamber 6 by means of a small cylindrical part 26 which forms part of the chamber 6 , at the top and inside.

Ici également on remarque les étranglements 8 et les conduites 9 qui relient entre elles toutes les chambres appartenant à une même série.Here also we notice the throttles 8 and the pipes 9 which interconnect all the rooms belonging to the same series.

Dans la forme d'exécution selon la figure 8, on fait usage en tant que ressort de contre-pression de la pression hydraulique ou pneumatique réglable dans la chambre 6 au-dessus de la membrane enroulable 24. Pour régler cette pression, on fait usage de vannes réglables, par exemple de petites vannes à billes 27.In the embodiment according to FIG. 8, use is made as a counter-pressure spring of the hydraulic or pneumatic pressure adjustable in the chamber 6 above the roll-up membrane 24. To adjust this pressure, use is made adjustable valves, for example small ball valves 27.

Dans la forme d'exécution suivant les figures 9, 10 et 11, qui représentent une seule et même structure dans trois positions actives différentes, on fait usage en tant que ressort de contre-pression, d'un ressort spiralé 28 qui est disposé autour de la biellette 5 et peut être comprimé entre la partie intérieure supérieure d'une chambre 6 et le fond interne 25' du piston 25. Les orifices de passage 29 sont prévus à la partie supérieure dans chacune des chambres 6 de la forme d'exécution suivant les figures 9, 10 et 11.In the embodiment according to FIGS. 9, 10 and 11, which represent a single and same structure in three different active positions, use is made as a counter-pressure spring, of a spiral spring 28 which is arranged around of the link 5 and can be compressed between the upper internal part of a chamber 6 and the internal bottom 25 'of the piston 25. The passage orifices 29 are provided at the upper part in each of the chambers 6 of the embodiment according to Figures 9, 10 and 11.

Dans la figure 9, l'espace 7 dans la chambre 6 déterminée par la membrane enroulable 24, est réduit à son volume minimum.In FIG. 9, the space 7 in the chamber 6 determined by the roll-up membrane 24, is reduced to its minimum volume.

La figure 10 montre une position intermédiaire dans laquelle le volume de l'espace 7 et le ressort spiralé 28 est ou va être soumis à un début de compression entre le fond 25' du piston 25 et le bord supérieur de la chambre 6.FIG. 10 shows an intermediate position in which the volume of the space 7 and the spiral spring 28 is or will be subjected to a start of compression between the bottom 25 'of the piston 25 and the upper edge of the chamber 6.

La figure 11 montre de quelle manière l'espace 7 atteint un volume maximum tandis que le ressort de contre-pression 28 est complètement enfoncé.Figure 11 shows how the space 7 reaches maximum volume while the back pressure spring 28 is fully depressed.

Les formes d'exécution selon les figures 12 et 13 montrent des dispositions particulières d'un ressort de pression (figure 12) et d'un ressort de traction (figure 13). Selon la figure 12, le ressort de contre-pression est saisi entre un téton 31 qui se déplace avec la biellette 5, attendu que le téton 31 est fixé sur un bras latéral 5' de la biellette 5. La partie supérieure du ressort de contre-pression 30 s'adapte dans un logement cylindrique 32 qui doit être considéré comme un élément fixe par rapport au châssis du lit ou du meuble.The embodiments according to Figures 12 and 13 show special arrangements of a pressure spring (Figure 12) and a tension spring (Figure 13). According to FIG. 12, the counter-pressure spring is gripped between a stud 31 which moves with the link 5, until the stud 31 is fixed on a lateral arm 5 ′ of the link 5. The upper part of the counter spring pressure 30 fits in a cylindrical housing 32 which must be considered as a fixed element relative to the frame of the bed or the furniture.

La forme d'exécution suivant la figure 13 comporte un élément 33 qui est fixe par rapport au châssis du lit. Cet élément présente à sa base et latéralement un bras 33' équipé d'une petite broche 34 autour de laquelle une extrémité du ressort de traction 35 est agrippée. A la partie supérieure, le ressort 35 se termine également par un crochet 36 auquel est soudée une petite broche 36' qui peut être déplacée le long de la chambre 37 du logement 38. Le logement cylindrique 38 forme un tout avec la biellette 5 qui est elle-même reliée à la latte 4. Lorsque la latte 4 est enfoncée vers le bas en même temps que la biellette 5, le logement 38 descendra sur une distance qui correspond environ à la longueur de la fente 37.The embodiment according to Figure 13 comprises an element 33 which is fixed relative to the frame of the bed. This element has at its base and laterally an arm 33 ′ equipped with a small pin 34 around which one end of the tension spring 35 is gripped. At the upper part, the spring 35 also ends with a hook 36 to which is welded a small pin 36 'which can be moved along the chamber 37 of the housing 38. The cylindrical housing 38 forms a whole with the link 5 which is itself connected to the batten 4. When the batten 4 is pressed down at the same time as the link 5, the housing 38 will descend over a distance which corresponds approximately to the length of the slot 37.

Dans la forme d'exécution suivant la figure 14, il est monté d'une manière sommaire comment il est possible, entre un élément fixe 39 (fixe par rapport au châssis du lit) et une biellette 5, de mettre sous tension un ressort de contre-pression, constitué de préférence par du caoutchouc ou un autre élastomère, et représenté par la référence 40, entre les tétons 41 et 42 appartenant respectivement à l'élément fixe 39 et à la biellette 5.In the embodiment according to FIG. 14, it is roughly mounted how it is possible, between a fixed element 39 (fixed relative to the bed frame) and a link 5, to tension a spring of back pressure, preferably made of rubber or another elastomer, and represented by the reference 40, between the pins 41 and 42 belonging respectively to the fixed element 39 and to the link 5.

Dans la forme d'exécution selon la figure 15, le ressort de contre-pression est formé par un cylindre 43. Un piston 44 est alors relié à la biellette 5, piston dont la base est reliée de manière fixe au bras latéral 5' de la biellette 5. Dans cette forme d'exécution, il est fait appel à un ressort pneumatique pour faire office de ressort de contre-pression.In the embodiment according to FIG. 15, the counter-pressure spring is formed by a cylinder 43. A piston 44 is then connected to the connecting rod 5, a piston whose base is fixedly connected to the lateral arm 5 ′ of the link 5. In this embodiment, an air spring is used to act as a counter-pressure spring.

La forme d'exécution selon les figures 16 et 17 est la même. La biellette 5 forme ici un tout avec une plaque 44 qui peut être déplacée dans un guidage 45 qui doit être considéré comme un élément fixe par rapport au châssis du lit. Sur le guidage 45 est fixé un ressort de torsion 46 qui appuie par son bras 46' contre une petite broche 47 qui est fixée dans la plaque 44.The embodiment according to Figures 16 and 17 is the same. The link 5 here forms a whole with a plate 44 which can be moved in a guide 45 which must be considered as a fixed element relative to the frame of the bed. On the guide 45 is fixed a torsion spring 46 which presses by its arm 46 'against a small pin 47 which is fixed in the plate 44.

Enfin, on peut également faire usage en tant que ressort de contre-pression d'un ressort à lame tel que ceci a été représenté aux figures 18 et 19. Le ressort de contre-pression formé par le ressort à lame 48 monté entre les petites broches 49, d'une part, et une butée 50, d'autre part, laquelle est fixée sur une pièce de support 51 qui est fixe par rapport au châssis du lit,exerce une pression sur la plaque 52 qui est reliée de manière fixe à la biellette 5.Finally, it is also possible to make use of a leaf spring as a counter-pressure spring as shown in FIGS. 18 and 19. The counter-pressure spring formed by the leaf spring 48 mounted between the small pins 49, on the one hand, and a stop 50, on the other hand, which is fixed on a support piece 51 which is fixed relative to the frame of the bed, exerts a pressure on the plate 52 which is fixedly connected with the link 5.

Il doit être entendu que la dans la description qui est donnée ci-dessus aucune distinction n'est faite entre les divers appuis d'une latte appartenant à un sommier à lattes. La présence d'un ressort de contre-pression dans tous les éléments qui sont soumis à la pression exercée sur les lattes n'est pas une nécessité absolue.It should be understood that in the description given above, no distinction is made between the various supports of a slat belonging to a slatted base. The presence of a back pressure spring in all the elements which are subjected to the pressure exerted on the slats is not an absolute necessity.

Pour diverses raisons d'ordre médical, les ressorts de contre-pression peuvent être localement supprimés ou modifiés.For various medical reasons, the back pressure springs can be locally removed or modified.
