Its movable part (6-7) is joined to its fixed part (1-3) by two sets of small rods which are each arranged on a side of the spring mattress, each of these two sets consisting of two small rods (10 and 13) forming an articulated quadrilateral with the fixed and movable parts so that the movement of raising the movable part is accompanied by a moving back of its lower end which prevents the mattress (9) sliding on the fixed and movable parts of the spring mattress. <IMAGE>

Description

On connait des sommiers comportant une partie fixe et, du côté de la tête, une partie mobile relevable, le matelas reposant simultanément sur cette partie fixe et sur cette partie mobile.Box springs are known comprising a fixed part and, on the side of the head, a lifting movable part, the mattress resting simultaneously on this fixed part and on this mobile part.

Dans les sommiers de ce genre actuellement réalisés la partie mobile est simplement articulée sur la partie fixe. Il en résulte un glissement du matelas sur cette partie mobile lorsqu'on modifie l'inclinaison de cette dernière.In box springs of this kind currently produced, the mobile part is simply articulated on the fixed part. This results in a sliding of the mattress on this mobile part when the inclination of the latter is modified.

Le brevet belge 511.324 décrit un canapé-lit comportant un siège relié par des biellettes à un caisson fixe. Le siège est constitué par un cadre rigide portant un sommier et un matelas. Le sommier est en une seule partie et lorsque l'inclinaison du siège est modifiée, il y a glissement du matelas sur le sommier.Belgian patent 511.324 describes a sofa bed comprising a seat connected by connecting rods to a fixed box. The seat consists of a rigid frame carrying a box spring and a mattress. The bed base is in one part and when the inclination of the seat is changed, there is sliding of the mattress on the bed base.

Le brevet suisse 357.517 décrit un siège transformable en surface de repos. Il comprend une assise et deux dossiers dont chacun comporte un coussin, est relié par des biellettes à l'assise, et est séparé de cette assise par une ligne de séparation. Les biellettes sont agencées pour que chaque dossier bascule autour d'un axe immatériel qui s'étend le long de la ligne de séparation et est confondu avec celui-ci. Le dossier pivote ainsi autour d'un axe fixe et son relèvement ne s'accompagne pas d'un recul de son extrémité inférieure.Swiss patent 357,517 describes a seat which can be transformed into a rest surface. It includes a seat and two backs, each of which includes a cushion, is connected by links to the seat, and is separated from this seat by a dividing line. The links are arranged so that each file swings around an immaterial axis which extends along the line of separation and coincides with it. The backrest thus pivots around a fixed axis and its raising is not accompanied by a decline in its lower end.

La présente invention a pour objet un sommier destiné à être recouvert par un matelas, comportant une partie fixe et, du côté de la tête, une partie mobile relevable, et agencé pour éviter tout glissement du matelas sur le sommier lors d'une variation de l'inclinaison de sa partie mobile.The subject of the present invention is a box spring intended to be covered by a mattress, comprising a fixed part and, on the side of the head, a movable lifting part, and arranged to avoid any sliding of the mattress on the bed base during a variation of the inclination of its mobile part.

Le sommier selon l'invention est caractérisé en ce que sa partie mobile est reliée à sa partie fixe par deux jeux de biellettes qui sont disposés chacun d'un côté du sommier, chacun de ces jeux étant constitué de deux biellettes formant un quadrilatère articulé avec les parties fixe et mobile de sorte que le mouvement de relèvement de la partie mobile s'accompagne d'un recul de son extrémité inférieure, ce qui évite le glissement du matelas sur les parties fixe et mobile du dossier.The bed base according to the invention is characterized in that its mobile part is connected to its fixed part by two sets of rods which are each arranged on one side of the bed base, each of these sets being made up of two rods forming a hinged quadrilateral with the fixed and mobile parts so that the lifting movement of the mobile part is accompanied by a decline in its lower end, which prevents the mattress from sliding over the fixed and mobile parts of the backrest.

Il peut être prévu un vérin pneumatique.de rappel verrouillable reliant les parties fixe et mobile pour compenser le poids de la partie mobile et immobiliser celle-ci dans la position désirée.A lockable pneumatic cylinder can be provided connecting the fixed and mobile parts to compensate for the weight of the mobile part and immobilize it in the desired position.

Dans un mode de réalisation avantageux de l'invention qui permet d'uniformiser l'effort de rappel exercé par le vérin et tendant à redresser la partie mobilè, il est prévu en outre deux câbles élastiques reliant la partie mobile, l'un à l'avant de la partie fixe et l'autre à l'arrière de celle-ci.In an advantageous embodiment of the invention which makes it possible to standardize the restoring force exerted by the jack and tending to straighten the movable part, there are also provided two elastic cables connecting the movable part, one to the 'front of the fixed part and the other at the back of it.

Il peut être prévu aussi un ressort antagoniste de faible longueur monté sur la tige de piston du vérin et entrant en jeu quand le vérin est au voisinage de sa partie complètement rentrée correspondant à la position horizontale de la partie mobile.There may also be provided an antagonistic spring of short length mounted on the piston rod of the jack and coming into play when the jack is in the vicinity of its fully retracted part corresponding to the horizontal position of the movable part.

On a décrit ci-après, à titre d'exemple non limitatif, un mode de réalisation du sommier selon l'invention, avec référence au dessin annexé dans lequel :

  • La Figure 1 est une vue en coupe longitudinale du sommier;
  • La Figure 2 est une vue par en dessous du sommier, à l'endroit de la liaison de sa partie mobile à sa partie fixe.
An embodiment of the bed base according to the invention has been described below, by way of non-limiting example, with reference to the appended drawing in which:
  • Figure 1 is a longitudinal sectional view of the box spring;
  • Figure 2 is a view from below of the box spring, at the location of the connection of its movable part to its fixed part.

Tel qu'il est représenté au dessin, le sommier comporte un cadre fixe rectangulaire 1 présentant dans sa partie centrale deux traverses 2a et 2b qui sont fixées au-dessus de longerons du cadre, sur lesquelles repose un coussin fixe 3, et sous lesquelles est fixé un tube longitudinal 5 sensiblement médian et disposé dans le plan du cadre. Il comporte également, du côté de la tête, un cadre mobile 6 sur lequel est fixé un coussin 7 et présentant deux traverses 8a et 8b. Le matelas 9 repose sur les deux coussins 3 et 7.As shown in the drawing, the bed base has a rectangular fixed frame 1 having in its central part two crosspieces 2a and 2b which are fixed above the side members of the frame, on which a fixed cushion 3 rests, and under which is fixed a substantially median longitudinal tube 5 and arranged in the plane of the frame. It also comprises, on the side of the head, a movable frame 6 on which is fixed a cushion 7 and having two crosspieces 8a and 8b. The mattress 9 rests on the two cushions 3 and 7.

Le cadre mobile 6 est relié au cadre fixe 1, de chaque côté, par une première biellette 10 qui est articulée en 11 sur le cadre 1 et en 12 sur le cadre 6, et par une seconde biellette 13 qui est articulée respectivement en 14 et 15 sur les deux cadres. Ces deux biellettes constituent avec les cadres un quadrilatère déformable. Le cadre 6 peut ainsi être déplacé depuis une position horizontale dans laquelle il repose sur le cadre 1, les deux coussins 3 et 7 étant alors dans le même plan et pratiquement jointifs, à une position relevée montrée à la Figure 1. Pendant ce mouvement, non seulement le cadre 6 pivote, mais son extrémité inférieure se déplace vers l'arriére, ce qui évite le glissement du matelas 9 sur les coussins 3 et 7.The movable frame 6 is connected to the fixed frame 1, on each side, by a first link 10 which is articulated at 11 on the frame 1 and at 12 on the frame 6, and by a second link 13 which is articulated at 14 and 15 respectively on the two frames. These two links constitute with the frames a deformable quadrilateral. The frame 6 can thus be moved from a horizontal position in which it rests on the frame 1, the two cushions 3 and 7 then being in the same plane and practically contiguous, to a raised position shown in FIG. 1. During this movement, not only does the frame 6 pivot, but its lower end moves towards the rear, which prevents the mattress 9 from sliding on the cushions 3 and 7.

Il est prévu des moyens élastiques pour équilibrer le poids du cadre 6 et celui du coussin 7 ainsi que l'effort exercé sur ce coussin par la partie supérieure du corps de l'utilisateur. Ces moyens comprennent un câble élastique 16 qui est plié en deux et dont les extrémités sont accrochées à un arceau 17 fixé à la traverse 8b du cadre 6. La partie centrale du câble passe sur un élément de réglage 18 qui est mobile sur une tige 19 solidaire de la partie tête du cadre 1 et peut être immobilisé dans la position désirée par coincement. Un deuxième câble élastique 20 forme une boucle qui relie un crochet 21 solidaire du tube 5 et un crochet 22 qui est fixé à une platine 29.Elastic means are provided to balance the weight of the frame 6 and that of the cushion 7 as well as the force exerted on this cushion by the upper part of the user's body. These means comprise an elastic cable 16 which is folded in two and the ends of which are hooked to a hoop 17 fixed to the cross-member 8b of the frame 6. The central part of the cable passes over an adjusting element 18 which is movable on a rod 19 secured to the head part of the frame 1 and can be immobilized in the desired position by wedging. A second elastic cable 20 forms a loop which connects a hook 21 secured to the tube 5 and a hook 22 which is fixed to a plate 29.

Il est par ailleurs prévu un vérin pneumatique de commande 23. Le cylindre de ce vérin est solidaire d'un déclencheur 24 qui est muni d'un levier de manoeuvre 25 et est monté pivotant en 26 sur le tube fixe 5. La tige de piston 27 du vérin est articulée en 28 sur la platine 29 fixée aux traverses 8a et 8b. Un ressort 30 est monté sur la tige 27 de façon à n'entrer en action que lorsque cette tige est complètement rentrée dans le cylindre.A pneumatic control cylinder 23 is also provided. The cylinder of this cylinder is integral with a trigger 24 which is provided with an operating lever 25 and is pivotally mounted at 26 on the fixed tube 5. The piston rod 27 of the jack is articulated at 28 on the plate 29 fixed to the crosspieces 8a and 8b. A spring 30 is mounted on the rod 27 so as to only come into action when this rod is fully retracted into the cylinder.

Le levier de manoeuvre 25 est relié par deux câbles 31 à une barre de commande transversale 32 qui est articulée en 33 sur le tube longitudinal 5 et est munie à l'une ou l'autre de ses extrémités d'une poignée de commande 34.The operating lever 25 is connected by two cables 31 to a transverse control bar 32 which is articulated at 33 on the longitudinal tube 5 and is provided at one or the other of its ends with a control handle 34.

Le cadre mobile 6 se trouvant dans une position donnée est verrouillé dans cette position par le vérin 23. Pour relever davantage ce cadre, l'utilisateur se met en position assise et manoeuvre la poignée 34 de façon à faire pivoter la barre de commande 32 et à actionner le levier 25 du déclencheur 24. Le vérin 23 est ainsi déverrouillé et son action ainsi que celle du câble élastique 16 assurent le relevage du cadre. Le câble élastique 20 s'oppose à ce relevage; mais il permet en combinaison avec le vérin 23 et le câble 16 d'obtenir un effort de redressement presque uniforme quelle que soit la position du cadre 6. Pour abaisser le cadre 6, l'utilisateur appuie avec son dos sur la partie tête du matelas 9, donc sur ce cadre 6, actionne la poignée 34 et déplace ledit cadre en surmontant l'action des moyens élastiques d'équilibrage.The movable frame 6 located in a given position is locked in this position by the jack 23. To raise this frame further, the user moves to the seated position and operates the handle 34 so as to pivot the control bar 32 and to actuate the lever 25 of the trigger 24. The jack 23 is thus unlocked and its action as well as that of the elas cable tick 16 ensure the lifting of the frame. The elastic cable 20 opposes this lifting; but it makes it possible, in combination with the jack 23 and the cable 16, to obtain an almost uniform straightening force whatever the position of the frame 6. To lower the frame 6, the user presses with his back on the head part of the mattress 9, therefore on this frame 6, actuates the handle 34 and moves said frame overcoming the action of the elastic balancing means.

L'effort nécessaire pour relever le cadre 6 est maximal lorsque ce cadre est horizontal et parallèle au cadre 1. Mais, à ce moment, le vérin 23 est en position complètement rentrée de sorte que le ressort 30 est comprimé. Son action s'ajoute à celle des autres moyens élastiques et facilite le relevage du cadre.The effort required to raise the frame 6 is maximum when this frame is horizontal and parallel to the frame 1. But, at this time, the jack 23 is in the fully retracted position so that the spring 30 is compressed. Its action is added to that of other elastic means and facilitates the lifting of the frame.
