Abstract

The support has side rails (2) delimiting a sleeping plane (4) and divided and articulated for modifying a longitudinal profile of the plane according to a suitable sleeping position. Units e.g. batten, of the plane are displaced axially along certain sections (2A-2E) of the rails during passage from one angular position of the sections to another position without changing the relative position of the units.

Description

La présente invention concerne un sommier articulé du type comprenant au moins deux longerons aptes à délimiter entre eux un plan de couchage, lesdits longerons étant sectionnés et articulés pour permettre de modifier le profil longitudinal du plan de couchage en fonction d'une position de couchage souhaitée ainsi qu'un longeron pour un tel sommier.The present invention relates to an articulated bed base of the type comprising at least two longitudinal members able to delimit between them a coating plane, said longitudinal members being cut and articulated to allow the longitudinal profile of the coating plane to be modified as a function of a desired coating position. as well as a spar for such a bed base.

Les sommiers articulés sont bien connus à ceux versés dans cet art, comme l'illustre en particulier le brevet FR-A-2.798.270 du présent demandeur. Un sommier articulé est généralement logé à l'intérieur d'un cadre fixe de sommier. Les longerons du sommier articulé sont reliés entre eux par des traverses et un dispositif de déplacement des différentes sections des longerons s'étend entre éléments du cadre fixe et éléments du cadre constitutif du sommier articulé. Ce mécanisme de déplacement des sections de longerons du sommier articulé entre différentes positions est constitué essentiellement de vérins et de pièces de liaison de type biellette entre les différents éléments constitutifs du sommier articulé. Ce mécanisme ne sera pas décrit plus en détail car il est bien connu à ceux versés dans cet art.Articulated bed springs are well known to those skilled in the art, as illustrated in particular in FR-A-2,798,270 of the present applicant. An articulated bed base is generally housed inside a fixed bed frame. The spars of the articulated bed frame are interconnected by cross members and a device for moving the different sections of the spars extends between elements of the fixed frame and elements of the frame constituting the articulated bed base. This mechanism for moving the longitudinal member sections of the mattress hinged between different positions consists essentially of cylinders and link type link between the various components of the articulated bed. This mechanism will not be described in more detail because it is well known to those versed in this art.

Jusqu'à présent, dans le cadre d'une telle conception, les sections de longeron du sommier articulé sont destinées à porter les éléments constitutifs du plan de couchage. Ces éléments constitutifs du plan de couchage sont généralement constitués de lattes, qui s'étendent entre lesdites sections en regard des longerons, et qui sont reliées à ces dernières par des éléments de support qui constituent souvent en outre des éléments de suspension desdites lattes.So far, in the context of such a design, the beam sections of the hinged bed are intended to carry the elements of the sleeping plane. These elements constituting the coating plane generally consist of slats, which extend between said sections opposite the longitudinal members, and which are connected thereto by support elements which often furthermore constitute suspension elements of said slats.

Ces éléments supports des lattes sont fixés de manière stationnaire aux sections de longerons du sommier articulé. Ils sont donc solidaires en déplacement desdites sections lors du passage du plan de couchage d'une position à une autre. De ce fait, même si les lattes sont disposées à intervalle régulier dans la position de couchage, dite horizontale, dans laquelle le plan de couchage s'étend dans le plan du cadre fixe de sommier, on constate, dès que le couchage occupe une position relevée, dans laquelle il forme un angle avec le cadre fixe du sommier, la formation d'espaces importants ou de zones de chevauchement au niveau des zones de sectionnement des longerons. Dans ces zones de sectionnement, le soutien du matelas n'est plus assuré de manière correcte, pouvant générer des zones d'inconfort au niveau de ces zones de sectionnement.These support elements of the slats are stationarily fixed to the sections of longitudinal members of the articulated bed. They are therefore integral in displacement of said sections during the passage of the coating from one position to another. Therefore, even if the slats are arranged at regular intervals in the so-called horizontal laying position, in which the plane of bedding extends in the plane of the fixed bed frame, it is noted, as soon as the bed occupies a raised position, in which it forms an angle with the fixed frame of the bed base, the formation of large spaces or areas of overlap at level of sectioning zones of the longitudinal members. In these sectioning zones, the support of the mattress is no longer ensured in a correct way, which can generate areas of discomfort at these cutting zones.

D'autres solutions, qui appartiennent à l'arrière-plan technologique de l'invention, ont été développées comme l'illustrent en particulier les demandes de brevet EP-A-0.774.223, EP-A-0.641.534 et EP-A-0.608.635. Dans ces solutions, c'est le plan de couchage ou sommier qui est déformable, ce qui pose les mêmes problèmes de formation d'espaces importants entre lattes dans une configuration par exemple convexe du plan de couchage.Other solutions, which belong to the technological background of the invention, have been developed as illustrated in particular by the patent applications EP-A-0.774.223, EP-A-0.641.534 and A-0608635. In these solutions, it is the sleeping plane or bed base that is deformable, which poses the same problems of forming large spaces between slats in a convex configuration eg of the sleeping plane.

Un but de la présente invention est donc de proposer un sommier articulé dont la conception permet de conserver sensiblement la position relative des traverses constitutives du plan de couchage quelle que soit la position du plan de couchage.An object of the present invention is therefore to provide an articulated bed base whose design allows to substantially maintain the relative position of the sleepers constituting the coating plane regardless of the position of the coating plane.

Un autre but de la présente invention est de proposer un sommier articulé dont la conception permet d'éviter aux traverses du plan de couchage de se toucher en position relevée.Another object of the present invention is to provide an articulated bed base whose design avoids the sleepers of the sleeping plane to touch in the raised position.

Un autre but de la présente invention est de proposer un sommier articulé dont la conception permet une simplification du mécanisme de relevage, en particulier au niveau de la zone de tête du sommier encore appelée têtière.Another object of the present invention is to provide an articulated bed base whose design allows a simplification of the lifting mechanism, particularly at the head zone of the bed base also called headrest.

Un autre but de la présente invention est de proposer un sommier articulé dont la conception permet de simplifier la fabrication et le montage de ce dernier.Another object of the present invention is to provide an articulated bed base whose design simplifies the manufacture and assembly of the latter.

A cet effet, l'invention a pour objet un sommier articulé du type comprenant au moins deux longerons aptes à délimiter entre eux un plan de couchage, lesdits longerons étant sectionnés et articulés pour permettre de modifier le profil longitudinal du plan de couchage en fonction d'une position de couchage souhaitée, caractérisé en ce que les éléments constitutifs du plan de couchage sont déplaçables axialement le long d'au moins certaines sections des longerons lors du passage d'une position angulaire des sections de longeron à une autre position sans modifier sensiblement la position relative desdits éléments constitutifs du plan de couchage entre eux.For this purpose, the subject of the invention is an articulated bed base of the type comprising at least two longitudinal members capable of delimiting between them a coating plane, said longitudinal members being sectioned and articulated so as to make it possible to modify the longitudinal profile of the coating plane as a function of a desired coating position, characterized in that the components of the coating plane are axially displaceable along at least some sections of the longitudinal members when passing from one angular position of the spar sections to another position without substantially changing the relative position of said elements of the sleeping plane between them.

Le déplacement axial des éléments constitutifs du plan de couchage le long des longerons du sommier articulé permet ainsi de conserver la répartition des éléments constitutifs du plan de couchage, en particulier des traverses ou lattes constitutives du plan de couchage, quelle que soit la position de couchage adoptée.The axial displacement of the elements constituting the coating plane along the longitudinal members of the articulated bed base thus makes it possible to maintain the distribution of the elements constituting the coating plane, in particular the crosspieces or slats constituting the coating plane, whatever the sleeping position adopted.

En outre, grâce à ce déplacement axial, le soutien du matelas est amélioré, notamment dans la zone de tête du sommier et permet d'obtenir un résultat équivalent à un résultat obtenu avec un montage télescopique de la partie de tête ou têtière du sommier articulé.In addition, thanks to this axial displacement, the support of the mattress is improved, especially in the head region of the bed base and provides a result equivalent to a result obtained with a telescopic mounting of the head portion or headrest of the articulated bed base .

Enfin, une telle conception du sommier permet une simplification du montage des éléments constitutifs du plan de couchage sur les longerons et un temps de pose réduit.Finally, such a design of the bed base allows a simplification of the assembly of the components of the coating plane on the side members and a reduced exposure time.

En outre, le nombre de pièces est réduit et de ce fait le risque de perte de telles pièces est limité.In addition, the number of parts is reduced and therefore the risk of loss of such parts is limited.

La présente invention a encore pour objet un longeron pour sommier articulé du type comprenant au moins deux longerons aptes à délimiter entre eux un plan de couchage, ledit longeron étant formé d'éléments sectionnés et articulés pour permettre de modifier le profil longitudinal du plan de couchage en fonction d'une position de couchage souhaitée, caractérisé en ce qu'au moins certaines sections du longeron sont conformées pour constituer une coulisse pour permettre un déplacement axial des éléments constitutifs du plan de couchage lors du passage d'une position angulaire des sections de longeron à une autre position.Another subject of the present invention is a spar for an articulated bed base of the type comprising at least two spars capable of delimiting between them a bedding plane, said spar being formed of sectioned and articulated elements in order to make it possible to modify the longitudinal profile of the sleeping plane. according to a desired coating position, characterized in that at least some sections of the spar are shaped to form a slide to allow axial displacement of the constituent elements of the plane of when moving from one angular position of the spar sections to another position.

The invention will be better understood on reading the following description of exemplary embodiments, with reference to the appended drawings in which:

Comme mentionné ci-dessus, le sommier 1 articulé, objet de l'invention, comprend au moins deux longerons 2 aptes à délimiter entre eux un plan 4 de couchage. Dans le cas d'un couchage pour deux personnes, il est prévu deux sommiers articulés positionnés côte à côte comme l'illustre la figure 8. Indépendamment du nombre de sommiers retenu, il est associé à ce sommier articulé au moins un sommier rigide stationnaire affectant la forme d'un cadre. Dans l'exemple représenté, ce cadre s'étend autour des deux sommiers articulés. Ce cadre stationnaire est constitué de traverses et de longerons reliés entre eux. Ce cadre est généralement équipé de piétements. Les longerons du sommier articulé sont également reliés entre eux par des traverses. Entre les éléments du sommier articulé et les éléments du cadre de sommier stationnaire, il est prévu un mécanisme d'entraînement en déplacement des sections de longerons constitutifs du sommier articulé. En effet, les longerons 2 du sommier articulé sont réalisés sous forme d'éléments sectionnés et articulés pour permettre de modifier le profil longitudinal du plan 4 de couchage en fonction d'une position de couchage souhaitée. A cet effet, chaque section de longeron est reliée directement ou à l'aide d'une traverse à un mécanisme de monte et baisse apte à mouvoir lesdites sections de longerons en fonction de la position de couchage souhaitée. Ce mécanisme de monte et baisse qui agit sur les différentes sections de longerons et qui est constitué essentiellement de vérins et de biellettes ne sera pas décrit plus en détail car il est bien connu à ceux versés dans cet art. En général, un tel sommier articulé comporte cinq sections de longerons qui sont représentées en 2A à 2E aux figures. Les sections d'extrémités, représentée en 2A et 2E, constituent l'une la section de tête du sommier articulé encore appelée têtière, l'autre la section de pied du sommier. On obtient ainsi, dans une position de couchage, un relevage du buste de l'utilisateur et des pieds de l'utilisateur. Cette position, qui correspond à celle représentée à la figure 2, est appelée position de confort. La position des sections de longerons du sommier, représentée à la figure 1, correspond en général à la position occupée par l'utilisateur pendant les phases de sommeil. Dans cette position de couchage, les sections des longerons sont alignées pour former un plan de couchage parfaitement horizontal. Bien évidemment, entre les figures 1 et 2, qui représentent deux positions de couchage, les sections de longerons peuvent être déplacées pour occuper des positions de couchage intermédiaires qui ne seront pas décrites ci-après.As mentioned above, the articulated bed base 1, object of the invention, comprises at least two longitudinal members 2 capable of delimiting between them a plane 4 of coating. In the case of a bed for two people, it is provided two articulated bed bases positioned side by side as shown in Figure 8. Regardless of the number of bed bases retained, it is associated with this articulated bed base at least one stationary rigid bed base affecting the shape of a frame. In the example shown, this frame extends around the two articulated bed bases. This stationary frame consists of cross members and beams connected together. This frame is usually equipped with legs. The rails of the articulated bed frame are also interconnected by sleepers. Between the elements of the articulated bed base and the elements of the stationary bed frame, there is provided a mechanism for moving the sections of longitudinal members constituting the articulated bed. Indeed, the longitudinal members 2 of the hinged bed are made in the form of sectioned and articulated elements to allow to modify the longitudinal profile of the coating plane 4 according to a desired coating position. For this purpose, each spar section is connected directly or with the aid of a cross member to a raising and lowering mechanism capable of moving said sections of spars according to the desired sleeping position. This up and down mechanism which acts on the different sections of spars and which consists essentially of jacks and rods will not be described in more detail because it is well known to those skilled in this art. In general, such an articulated bed base comprises five sections of longitudinal members which are represented at 2A to 2E in the figures. The end sections, shown in 2A and 2E, constitute one of the head section of the articulated bed base also called headrest, the other the foot section of the bed base. Thus, in a sleeping position, a lifting of the bust of the user and the feet of the user is obtained. This position, which corresponds to that shown in Figure 2, is called the comfort position. The position of the sections of longitudinal members of the bed frame, shown in Figure 1, corresponds in general to the position occupied by the user during the sleep phases. In this sleeping position, the sections of the longitudinal members are aligned to form a perfectly horizontal sleeping plane. Of course, between Figures 1 and 2, which represent two sleeping positions, the sections of rails can be moved to occupy intermediate sleeping positions that will not be described below.

De manière caractéristique à l'invention, les éléments constitutifs du plan 4 de couchage sont déplaçables axialement le long d'au moins certaines sections 2A, 2B, 2D, 2E des longerons 2 lors du passage d'une position angulaire des sections 2A, 2B, 2C, 2D, 2E de longeron 2 à une autre position sans modifier sensiblement la position relative desdits éléments constitutifs du plan 4 de couchage entre eux. Ainsi, comme l'illustre le passage de la figure 1 à la figure 2, les éléments constitutifs du plan de couchage sont déplacés axialement pour s'étendre, côté tête, au-delà de l'extrémité libre du longeron et, à l'inverse, s'étendre, côté pieds, en retrait de l'extrémité libre du longeron comme l'illustrent les vues de détail 3 et 4. Ce déplacement des éléments du plan de couchage correspond au passage d'une position horizontale du plan de couchage à une position relevée de ce plan de couchage. Pour obtenir un tel déplacement axial des éléments constitutifs du plan 4 de couchage, lors du passage d'une position angulaire à une autre des sections de longeron, au moins certaines des sections des longerons 2 du plan 4 de couchage sont conformées pour constituer des coulisses 3. Parallèlement, les éléments constitutifs du plan 4 de couchage comprennent au moins un coulisseau 5 logé dans la coulisse 3 du longeron 2, ce coulisseau 5 étant apte à se déplacer axialement dans la coulisse 3 du longeron 2 au cours du passage d'une position angulaire à une autre position des sections de longeron. On note que ces déplacements à coulissement des éléments constitutifs du plan 4 de couchage au-delà des extrémités libres des longerons dans la partie tête du sommier permettent d'offrir un meilleur soutien du matelas dans cette position relevée du sommier articulé. Tel n'était pas le cas dans l'état de la technique où il était nécessaire d'avoir des dispositifs complexes pour obtenir un déplacement télescopique de la partie têtière du sommier articulé.Characteristically to the invention, the elements constituting the coating plane 4 are axially displaceable along at least some sections 2A, 2B, 2D, 2E of the longitudinal members 2 during the passage of an angular position of the sections 2A, 2B , 2C, 2D, 2E of spar 2 to another position without substantially changing the relative position of said elements of the plane 4 sleeping between them. Thus, as illustrated by the passage of FIG. 1 to FIG. 2, the elements constituting the coating plane are moved axially to extend, on the head side, beyond the free end of the spar and, at inverse, extend, on the feet side, back from the free end of the spar as shown in detail views 3 and 4. This displacement of the elements of the coating plane corresponds to the passage of a horizontal position of the sleeping plane at a raised position of this sleeping plane. To obtain such axial displacement of the elements constituting the coating plane 4, during the passage from one angular position to another of the spar sections, at least some of the sections of the longitudinal members 2 of the plane 4 of coating are shaped to form backstage 3. In parallel, the constituent elements of the coating plane 4 comprise at least one slide 5 housed in the slide 3 of the spar 2, this slider 5 being able to move axially in the slide 3 of the spar 2 during the passage of a angular position at another position of the spar sections. It is noted that these sliding displacements of the elements constituting the plane 4 of coating beyond the free ends of the longitudinal members in the head portion of the bed base allow to provide better support of the mattress in this raised position of the articulated bed. This was not the case in the state of the art where it was necessary to have complex devices to obtain a telescopic movement of the head portion of the articulated bed.

Dans les exemples représentés, les éléments constitutifs du plan 4 de couchage comprennent, outre le coulisseau 5 logé dans la coulisse 3 du longeron 2, des supports 6 de réception de traverse 10 support de matelas. Ces supports 6 de réception de traverses 10 sont portés par le coulisseau 5.In the examples shown, the elements constituting the coating plane 4 comprise, in addition to the slider 5 housed in the slider 3 of the spar 2, supports 6 for receiving the support 10 mattress support. These supports 6 receiving crosspieces 10 are carried by the slider 5.

Dans l'exemple représenté à la figure 5, les supports 6 de réception de traverses 10 sont réalisés monoblocs avec le coulisseau 5. Ces supports 6 de réception de traverses 10 constituent des éléments de suspension des traverses 10 de réception du matelas.In the example shown in FIG. 5, the supports 6 for receiving crosspieces 10 are made in one piece with the slide 5. These supports 6 for receiving crosspieces 10 constitute suspension elements for the sleepers 10 for receiving the mattress.

Ainsi, dans les exemples représentés, un sommier articulé comporte à chaque fois deux longerons parallèles formant coulisse. Chaque coulisse est équipée d'un coulisseau 5. Ce coulisseau 5, qui affecte la forme générale d'une barrette, est de préférence constitué de deux éléments fixés chacun à une extrémité à une section de longeron 2. Ainsi, lorsque le longeron est constitué de cinq sections 2A, 2B, 2C, 2D, 2E, la section médiane, représentée en 2C aux figures, est une section fixe sur laquelle les deux barrettes constitutives du coulisseau 5 sont fixées par une de leurs extrémités. Ainsi, l'une des barrettes sera montée à coulissement dans la coulisse formée par les sections 2D et 2E de longeron, tandis que l'autre barrette sera montée à coulissement dans la coulisse formée par les sections 2A et 2B de longeron. Bien évidemment, la barrette du coulisseau aurait pu être réalisée d'une seule pièce pour couvrir les sections 2A à 2E de longeron. Toutefois, elle nécessitait, dans ce cas, la réalisation d'un moule de grande dimension augmentant le coût de l'ensemble. En effet, généralement, le coulisseau 5 et les supports 6 de réception des traverses 10 sont réalisés par moulage. Ces supports 6 de réception des traverses 10 sont réalisés sous forme d'un corps présentant une section 9 de fixation au coulisseau 5, une section 7 de palier destinée à supporter au moins une extrémité de traverse, généralement réalisée sous forme d'une latte, cette extrémité de traverse étant montée de préférence libre à coulissement dans la section 7 de palier et, intercalée entre les sections de fixation et de palier, une section 8 de suspension. Cette section 8 de suspension est réalisée ici sous forme de deux branches, l'une dite supérieure, l'autre inférieure, d'un ressort qui présente un profil en forme générale de V couché, la zone de liaison entre lesdites branches du ressort étant située à l'intérieur du cadre de sommier. Ceci ne constitue toutefois qu'un exemple de réalisation d'un tel support de réception.Thus, in the examples shown, an articulated bed base comprises each time two parallel longitudinal members forming a slide. Each slide is equipped with a slider 5. This slider 5, which affects the general shape of a bar, is preferably constituted by two elements each fixed at one end to a section of spar 2. Thus, when the spar consists of of five sections 2A, 2B, 2C, 2D, 2E, the middle section, shown in 2C in the figures, is a fixed section on which the two constituent strips of the slider 5 are fixed by one of their ends. Thus, one of the bars will be slidably mounted in the slide formed by the sections 2D and 2E spar, while the other bar will be slidably mounted in the slide formed by sections 2A and 2B spar. Of course, the bar of the slider could have been made in one piece to cover the sections 2A to 2E spar. However, it required, in this case, the realization of a mold of large size increasing the cost of all. Indeed, generally, the slider 5 and the supports 6 for receiving the cross members 10 are made by molding. These supports 6 for receiving the crosspieces 10 are made in the form of a body having a securing section 9 to the slider 5, a bearing section 7 intended to support at least one end of the cross member, generally made in the form of a slat, this crosshead end being preferably free to slide in the bearing section 7 and, interposed between the fastening and bearing sections, a section 8 of suspension. This suspension section 8 is made here in the form of two branches, one said upper and the other lower, of a spring which has a generally V-shaped profile, the connection zone between said branches of the spring being located inside the box spring frame. This, however, is only an example of realization of such a receiving medium.

Les traverses 10 supports du matelas affectent quant à elles la forme de lattes généralement cintrées pour présenter un profil convexe à convexité tournée vers le matelas.The mattress supports 10 affect the form of slats generally bent to present a convex profile convexity facing the mattress.

Chaque section 7 de palier du support 6 de réception affecte donc la forme d'une poche qui reçoit à coulissement libre l'extrémité l'une latte.Each bearing section 7 of the receiving support 6 therefore has the shape of a pocket which receives the end sloping one slat free.

Ainsi, un sommier articulé comporte deux longerons 2. Chaque longeron reçoit, logé à l'intérieur de sa coulisse 3, un coulisseau 5 auquel est associée une série de supports 6 de réception de traverse 10. Une fois le coulisseau et ses supports de réception 6 positionnés dans la coulisse, les traverses 10 peuvent être positionnées entre les supports 6 de réception se faisant face. Le résultat obtenu est conforme à celui représenté à la figure 8 dans laquelle les lattes s'étendent parallèlement les unes aux autres, perpendiculairement aux sections de longerons. On note que l'intervalle entre les lattes est relativement faible et est de valeur constante d'un intervalle à un autre. Cet intervalle sera conservé lors du passage des sections de longeron d'une position de couchage horizontale, telle que celle représentée à la figure 1, à une position relevée du sommier, telle que celle représentée à la figure 2, alors que ce n'était pas le cas dans l'état de la technique. Dans les exemples représentés, les coulisses 3 équipant les longerons 2 affectent la forme de glissières ouvertes le long d'une génératrice pour le passage des supports 6 de réception des traverses 10. La coulisse est ainsi positionnée au sommet du longeron qui affecte la forme d'un profilé d'allure générale quadrangulaire. Cette coulisse forme un rail délimitant une cavité ouverte sur sa face du dessus pour le déplacement à coulissement des supports 6 de réception des traverses portés par le coulisseau 5. L'ouverture 11 de cette glissière ou coulisse est élargie au voisinage des zones de sectionnement des longerons 2 pour permettre la sortie partielle du coulisseau 5 de la coulisse 3, en particulier lorsqu'on réduit l'angle entre deux sections 2A, 2B, 2C, 2D, 2E de longerons 2 de ladite zone. Cet élargissement 12 de la coulisse au voisinage de la zone de sectionnement est plus particulièrement représenté à la figure 7. La sortie du coulisseau de la coulisse est quant à elle visible à la figure 2. Il peut être noté notamment, au voisinage de la zone de sectionnement des sections 2C et 2B du longeron, que le coulisseau 5 s'étend en dehors de la coulisse 3. Ainsi, le coulisseau est réalisé en un matériau élastiquement déformable pour pouvoir présenter un profil courbe lorsque les sections de longerons, au droit desquelles il s'étend, forment un angle différent de 180° entre elles.Thus, an articulated bed base comprises two longitudinal members 2. Each spar receives, housed inside its slide 3, a slider 5 which is associated with a series of supports 6 crossbar reception 10. Once the slider and its receiving supports 6 positioned in the slide, the cross members 10 can be positioned between the receiving supports 6 facing each other. The result obtained is consistent with that shown in Figure 8 wherein the slats extend parallel to each other, perpendicular to the sections of longitudinal members. Note that the interval between the slats is relatively small and is of constant value from one interval to another. This interval will be maintained during the passage of the spar sections of a horizontal sleeping position, such as that shown in Figure 1, to a raised position of the bed, such as that shown in Figure 2, while it was not not the case in the state of the art. In the examples shown, the slides 3 equipping the longitudinal members 2 affect the shape of slides open along a generator for the passage of the supports 6 for receiving the cross members 10. The slide is thus positioned at the top of the spar which affects the shape of the a profile of general shape quadrangular. This slide forms a rail delimiting a cavity open on its top face for the sliding movement of the supports 6 for receiving the sleepers carried by the slide 5. The opening 11 of this slide or slide is widened in the vicinity of the cutting zones of the longitudinal members 2 to allow the partial release of the slide 5 of the slide 3, in particular when the angle between two sections 2A, 2B, 2C, 2D, 2E of the longitudinal members 2 of said zone is reduced. This widening 12 of the slide in the vicinity of the sectioning zone is more particularly shown in FIG. 7. The output of the sliding slide is for its part visible in FIG. 2. It can be noted in particular, in the vicinity of the sectioning zone of the sections 2C and 2B of the spar, that the slider 5 extends outside the slider 3. Thus, the slider is made of an elastically deformable material to be able to present a curved profile when the sections of spars, to the right of which it extends, form an angle different from 180 ° between them.

Cette conformation des coulisses au voisinage des zones de sectionnement permet d'augmenter la prise d'angle entre les différentes sections de longerons.This conformation of the slides in the vicinity of the sectioning zones makes it possible to increase the corner angle between the different sections of spars.

Le fonctionnement d'un tel sommier articulé est donc identique à celui de l'état de la technique. En effet, les sections articulées se déplacent de manière analogue à ce qui peut être décrit dans l'état de la technique. La seule différence résulte des éléments constitutifs du plan de couchage qui, au lieu d'être positionnés de manière stationnaire sur les sections de longeron, se déplacent axialement le long de certaines des sections de longeron au cours du déplacement des sections de longeron d'une position de couchage à une autre.The operation of such an articulated bed base is therefore identical to that of the state of the art. Indeed, the articulated sections move similarly to what can be described in the state of the art. The only difference results from the elements of the coating plane which, instead of being stationarily positioned on the spar sections, move axially along some of the spar sections during the displacement of the spar sections of a spar. sleeping position to another.

Grâce à cette disposition, il en résulte la possibilité de conserver une configuration des éléments du plan de couchage et, en particulier de l'intervalle entre lattes, similaire quelle que soit la position de couchage occupée.With this arrangement, it results in the possibility of maintaining a configuration of the elements of the coating and, in particular the interval between slats, similar regardless of the sleeping position occupied.

En outre, le support du matelas, côté tête du sommier, est conservé en position relevée du sommier.In addition, the mattress support, head side of the bed base, is kept in the raised position of the bed frame.

Enfin, le montage d'un tel sommier, et en particulier des éléments constitutifs du plan de couchage sur les longerons du sommier, est facilité. Il suffit en effet d'introduire le coulisseau dans la coulisse constitutive du longeron puis de positionner les traverses dans les supports 6 de réception desdites traverses formant un ensemble monobloc avec le coulisseau. Dans l'état de la technique, il est généralement nécessaire de fixer chaque support 6 de réception d'une traverse au longeron avant de pouvoir positionner la latte à l'intérieur dudit support. II en résulte un temps de montage relativement important. Il est en outre nécessaire de disposer de pièces de fixation, telles que vis, et de réaliser des perçages dans les longerons. Tel n'est plus le cas dans la conception retenue où le montage s'avère désormais extrêmement simple du fait que les supports 6 de réception des traverses forment un ensemble monobloc avec le coulisseau 5 qu'il suffit d'enfiler dans la coulisse 3 fermée par chaque longeron.Finally, the mounting of such a bed base, and in particular of the elements constituting the sleeping plane on the longitudinal members of the bed frame, is facilitated. It suffices to introduce the slide in the constituent slide of the beam and then position the cross members in the supports 6 for receiving said cross members forming a one-piece assembly with the slide. In the state of the art, it is generally necessary to fix each support 6 for receiving a crossbar to the spar before being able to position the slat inside said support. This results in a relatively large mounting time. He is in additionally necessary to have fasteners, such as screws, and to make holes in the longitudinal members. This is no longer the case in the selected design where the assembly is now extremely simple because the supports 6 for receiving the sleepers form a one-piece assembly with the slider 5 that simply put in the slide 3 closed by each spar.
