Description

La présente invention concerne le domaine de l'industrie de l'ameublement. Elle concerne plus particulièrement un perfectionnement aux dispositifs d'assise ou de couchage pour châssis de sommier ou de siège, ce dispositif comprenant une pluralité de moyens de soutien corporels transversaux de type lattes ou traverses, qui forment une surface d'assise ou de couchage, lesquels moyens de soutien corporels sont interposés entre deux longerons en regard dudit châssis, et sont solidarisés avec lesdits longerons de châssis par l'intermédiaire d'éléments supports d'extrémités.The present invention relates to the field of the furniture industry. It relates more particularly to an improvement to the seat or bedding devices for bed frame or seat, this device comprising a plurality of transverse body support means latches or sleepers, which form a seating surface or sleeping, which body support means are interposed between two longitudinal members facing said frame, and are secured to said chassis side members by means of end support members.

Dans certains dispositifs connus de ce type, tous les moyens de soutien corporels transversaux (lattes ou traverses) sont fixés sur le châssis de sommier ou de siège par l'intermédiaire d'éléments supports d'extrémités indépendants les uns des autres (voir par exemple les documents FR-2 409 726 ou EP-0 428 227 ).In some known devices of this type, all transverse body support means (slats or sleepers) are fixed on the bed frame or seat by means of end support members independent of each other (see for example the documents FR-2 409 726 or EP-0 428 227 ).

Mais, malgré la flexibilité verticale des éléments supports d'extrémités, ces structures ne permettent pas aux différents moyens de soutien transversaux d'épouser de manière optimale les courbes corporelles de l'utilisateur.But, despite the vertical flexibility of the end support elements, these structures do not allow the different transverse support means to optimally marry the body curves of the user.

On connaît encore des dispositifs dans lesquels les lattes ou les traverses sont montées dépendantes les unes par rapport aux autres, et tendent à s'auto-équilibrer en effort.
De telles structures, par exemple décrites dans les documents DE-38 15 098 , FR-2 912 299 ou encore DE-20 2007 014 448 , sont cependant relativement complexes et s'adaptent difficilement aux sommiers de type relevables standard.Devices are still known in which the slats or sleepers are mounted dependent on each other, and tend to self-balance in effort.
Such structures, for example described in the documents DE-38 15,098 , FR-2 912 299 or DE-20 2007 014 448 are, however, relatively complex and difficult to adapt to the standard liftable bed bases.

La présente invention propose une solution simple permettant de soutenir l'utilisateur de manière efficace et confortable.The present invention provides a simple solution to support the user in an efficient and comfortable manner.

Pour cela, conformément à l'invention telle que décrite par la revendication 1, dans le cadre d'un dispositif d'assise ou de couchage tel que défini ci-dessus, au moins trois des moyens de soutien corporels (dits moyens de soutien latéraux) qui sont équipés d'éléments supports d'extrémités munis de moyens de fixation sur les longerons de sommier ou de siège, sont séparés deux à deux par au moins un moyen de soutien corporel complémentaire dont les éléments supports d'extrémités
- sont portés par lesdits éléments supports fixés sur le longeron de châssis, et - sont solidarisés avec ces derniers par l'intermédiaire d'un organe élastique.For this, according to the invention as described by claim 1, in the context of a seating or sleeping device as defined above, at least three of the body support means (said lateral support means ) which are equipped with end support elements provided with fixing means on the bed frame or seat rails, are separated in pairs by at least one additional body support means, the end support elements of which
- Are carried by said support members attached to the frame member, and - are secured with the latter by means of an elastic member.

D'autre part, selon une caractéristique particulièrement intéressante, les éléments supports desdits moyens de soutien latéraux, disposés de part et d'autre dudit ou desdits moyens de soutien complémentaires, sont chacun montés pivotants sur leur longeron support, autour d'un axe perpendiculaire audit longeron et parallèle auxdits moyens de soutien.On the other hand, according to a particularly interesting characteristic, the support elements of said lateral support means, arranged on either side of said one or more complementary support means, are each pivotally mounted on their support spar, about a perpendicular axis. said spar and parallel to said support means.

De la sorte, les moyens de soutien corporels tendent à s'auto-équilibrer en effort, de plus, le ou les moyens de soutien complémentaires tendent à se répartir convenablement, de manière uniforme ou sensiblement uniforme, entre les deux points de fixation associés.In this way, the body support means tend to self-balance in effort, in addition, or the additional support means tend to be distributed appropriately, uniformly or substantially uniformly, between the two associated attachment points.

De plus, l'écartement entre deux moyens de soutien corporels ayant la possibilité de varier, ce système s'adapte facilement à un sommier relevable où les distances entre les longerons supports peuvent varier dans des proportions importantes. Ce système permet également, dans ce même cas de sommier relevable d'avoir des courbures générales douces lorsque le sommier est relevé.In addition, the spacing between two body support means having the ability to vary, this system easily adapts to a lift bed where the distances between the support rails can vary in significant proportions. This system also allows, in this case of liftable bed base to have soft general curvatures when the bed frame is raised.

Les éléments supports d'extrémités, en particulier des moyens de soutien latéraux, sont avantageusement munis :

  • de moyens pour la réception de l'extrémité d'un moyen de soutien corporel en forme de latte ou de traverse, et
  • d'un orifice pour la réception d'un tenon de fixation sur le longeron de châssis, permettant l'obtention d'une fixation pivotante dudit élément support autour dudit tenon.
The end support elements, in particular lateral support means, are advantageously provided with:
  • means for receiving the end of a slat-like or cross-member body support means, and
  • an orifice for receiving a fixing lug on the chassis spar, for obtaining a pivotal attachment of said support member around said lug.

Selon l'invention, plusieurs moyens de soutien corporels complémentaires sont interposés entre lesdits deux moyens de soutien latéraux, lesdits moyens de soutien corporels complémentaires étant solidarisés entre eux par l'intermédiaire d'un organe élastique.According to the invention, several complementary body support means are interposed between said two lateral support means, said complementary body support means being secured to each other by means of an elastic member.

Les organes élastiques utilisés comportent avantageusement au moins deux degrés de liberté entre leurs deux extrémités, l'un en flexion et l'autre en extension/compression.The elastic members used advantageously comprise at least two degrees of freedom between their two ends, one in flexion and the other in extension / compression.

Ces organes élastiques comportent avantageusement, entre leurs deux extrémités, deux couples de bras en Vé, orientés en vis-à-vis, les deux bras de chaque couple étant reliés par une articulation s'étendant perpendiculairement ou sensiblement perpendiculairement à la surface d'assise ou de couchage définie par les moyens de soutien corporels.These elastic members advantageously comprise, between their two ends, two pairs of Vee arms, oriented vis-a-vis, the two arms of each pair being connected by a joint extending perpendicularly or substantially perpendicularly to the seating surface or sleeping defined by the body support means.

Dans ce cadre, les deux bras en Vé de chaque couple sont avantageusement reliés entre eux par des moyens ressort de rappel qui tendent à les rapprocher l'un de l'autre.In this context, the two arms V of each pair are advantageously interconnected by return spring means which tend to bring them closer to each other.

Selon une forme de réalisation particulière, les organes élastiques et les éléments supports disposés de part et d'autre comportent des moyens de fixation amovibles (avantageusement du type à encastrement).According to a particular embodiment, the resilient members and the support members arranged on either side comprise removable fixing means (advantageously of the recessed type).

Dans ce cas, les deux couples de bras en Vé des organes élastiques peuvent être reliés par des tenons d'extrémités qui sont adaptés pour venir s'emboîter dans des logements complémentaires ménagés dans les éléments supports.In this case, the two pairs of V-arms of the elastic members may be connected by end tenons which are adapted to fit into complementary housings formed in the support elements.

Selon une variante de réalisation, les organes élastiques sont réalisés monoblocs avec lesdits éléments supports disposés de part et d'autre.According to an alternative embodiment, the elastic members are made in one piece with said support elements arranged on either side.

Selon encore une autre particularité, le châssis de sommier ou de siège comporte au moins deux éléments mobiles l'un par rapport à l'autre, aptes à pivoter ou à s'écarter l'un par rapport à l'autre, et deux moyens de soutien corporels latéraux, disposés de part et d'autre dudit ou desdits moyens de soutien complémentaires, sont fixés chacun sur l'un desdits deux éléments mobiles de châssis, et en particulier sur l'une des extrémités en regard desdits deux éléments mobiles de châssis.According to yet another feature, the bed frame or seat comprises at least two movable elements relative to each other, able to pivot or to deviate relative to each other, and two means lateral body support, arranged on either side of said one or more complementary support means, are each fixed on one of said two mobile frame members, and in particular on one of the opposite ends of said two movable elements of frame.

La figure 1 illustre de manière schématique un dispositif de couchage 1 conforme à l'invention monté sur un châssis de sommier 2, et sur lequel est allongé un utilisateur 3.The figure 1 schematically illustrates a coating device 1 according to the invention mounted on a bed frame 2, and on which is extended a user 3.

Ce dispositif de couchage 1 comprend une pluralité de moyens de soutien corporel, ici en forme de lattes 4, 4', dont les extrémités sont montées sur des éléments supports 5, 5' assurant la solidarisation avec le châssis de sommier 2.This coating device 1 comprises a plurality of body support means, here in the form of laths 4, 4 ', the ends of which are mounted on support elements 5, 5' ensuring the connection with the bed frame 2.

Les lattes 4, 4' sont en fait interposées horizontalement entre deux longerons 6 en regard du châssis 2 (un seul longeron 6 est visible sur la vue de côté de la figure 1). Ces lattes 4, 4' forment ensemble une surface de couchage S horizontale ou sensiblement horizontale, pour la réception de l'utilisateur 3.The slats 4, 4 'are in fact interposed horizontally between two longitudinal members 6 opposite the chassis 2 (only one spar 6 is visible in the side view of the figure 1 ). These slats 4, 4 'together form a sleeping surface S horizontal or substantially horizontal, for the reception of the user 3.

En pratique, le dispositif de couchage 1 reçoit un matelas pour optimiser le confort de l'utilisateur ; le matelas correspondant n'a pas été représenté sur la figure 1 par mesure de simplification.In practice, the coating device 1 receives a mattress to optimize the comfort of the user; the corresponding mattress was not represented on the figure 1 as a simplification measure.

Comme on peut le voir sur la figure 1 :

  • certains seulement des éléments supports (repérés 5) sont directement fixés sur les longerons de sommier 6, par l'intermédiaire de moyens de fixation 7 ; il s'agit des éléments supports d'extrémités, situés en tête et en pied de sommier, et de certains éléments supports intermédiaires, situés à des emplacements choisis sur la longueur du dispositif de couchage 1, et
  • les autres éléments supports (repérés 5') sont portés par ceux 5 directement fixés sur les longerons 6, et sont solidarisés avec ces derniers par l'intermédiaire d'un organe élastique 8.
As can be seen on the figure 1 :
  • only some of the support elements (marked 5) are directly attached to the bed frame rails 6, by means of fixing means 7; it is the end support elements, located at the top and bottom of the bed base, and some intermediate support elements, located at selected locations along the length of the coating device 1, and
  • the other support elements (labeled 5 ') are carried by those 5 directly fixed to the longitudinal members 6, and are secured thereto by means of an elastic member 8.

Les éléments supports 5 fixés directement sur les longerons 6 assurent la tenue d'ensemble du dispositif de couchage 1 sur le châssis de sommier 2, ils portent les lattes repérées 4.The support elements 5 fixed directly to the longitudinal members 6 ensure the overall holding of the coating device 1 on the bed frame 2, they carry the laths marked 4.

Les éléments supports 5' portent les lattes repérées 4' ; chacun de ces éléments supports 5' est associé à deux organes élastiques 8 positionnés de chaque côté, qui permettent sa solidarisation, soit avec un élément support 5 fixé directement sur le longeron 6, soit avec un élément support 5' non directement fixé sur le longeron 6 (lorsque plusieurs éléments supports 5' sont interposés entre deux éléments supports 5).The support elements 5 'bear the laths marked 4'; each of these support elements 5 'is associated with two elastic members 8 positioned on each side, which allow its attachment, either with a support member 5 fixed directly to the spar 6, or with a support member 5' not directly attached to the spar 6 (when several support elements 5 'are interposed between two support elements 5).

On comprend alors que les lattes 4' portées par les éléments supports 5' disposent de possibilités de mouvement importantes, tant en hauteur qu'en pivotement, pour répondre au mieux aux sollicitations d'appui de l'utilisateur ; en outre, ces lattes 4' tendent à se répartir uniformément entre les deux structures d'ancrage 5, 7 qui les bordent.It is then understood that the slats 4 'carried by the support members 5' have significant movement possibilities, both in height and pivoting, to best respond to the user's support stresses; in addition, these slats 4 'tend to be distributed uniformly between the two anchoring structures 5, 7 which border them.

De plus, les éléments supports 5 sont montés pivotants sur leur longeron support 6, par l'intermédiaire des moyens de fixation 7, autour d'un axe 7' qui est perpendiculaire auxdits longerons 6 et parallèle aux lattes 4, 4' (parallèles plus particulièrement à l'axe longitudinal des lattes 4, 4').In addition, the support elements 5 are pivotally mounted on their support beam 6, via the fastening means 7, about an axis 7 'which is perpendicular to said longitudinal members 6 and parallel to the slats 4, 4' (parallel plus particularly to the longitudinal axis of the slats 4, 4 ').

Ce montage pivotant autorise un basculement des éléments supports 5 autour de l'axe 7', permettant aux lattes 4' associées aux éléments supports 5' directement juxtaposés de part et d'autre, de tendre à s'auto-équilibrer en effort.This pivoting mounting allows tilting of the support elements 5 around the axis 7 ', allowing the slats 4' associated with the support elements 5 'directly juxtaposed on both sides, to tend to self-balance in effort.

La répartition sur le dispositif de couchage 1 des éléments supports 5 (fixés directement sur les longerons 6) et 5' (« en suspension », portés par les éléments 5 au moyen des organes élastiques 8), est fonction de la souplesse et des qualités de maintien que l'on souhaite obtenir au niveau des différentes zones corporelles de l'utilisateur.The distribution on the coating device 1 of the support elements 5 (attached directly to the longitudinal members 6) and 5 '("in suspension", carried by the elements 5 by means of the elastic members 8), is a function of the flexibility and qualities maintenance that is desired at the level of the different body areas of the user.

Par exemple, dans les zones d'appui important (épaules et hanches notamment) il peut être prévu plusieurs éléments supports 5' avec lattes 4', entre deux éléments supports ≪fixes≫ 5 (voir figure 1).For example, in the areas of major support (shoulders and hips in particular) there may be provided several support elements 5 'with slats 4', between two support elements "fixed" 5 (see figure 1 ).

Les caractéristiques d'élasticité des organes élastiques 8 sont également adaptées au maintien souhaité. Ces organes élastiques 8 disposent d'un degré de liberté en extension/compression parallèlement à la surface de couche S, permettant le rapprochement ou l'écartement élastique des deux éléments supports 5, 5' juxtaposés ; ils disposent encore d'un degré de liberté en flexion selon un axe perpendiculaire aux longerons 6 et parallèle à l'axe longitudinal des lattes 4, 4' (parallèle aussi à l'axe 7'), permettant aux éléments supports 5, 5' juxtaposés de pivoter l'un par rapport à l'autre.The elasticity characteristics of the elastic members 8 are also adapted to the desired maintenance. These elastic members 8 have a degree of freedom in extension / compression parallel to the layer surface S, allowing the approximation or the elastic separation of the two support elements 5, 5 'juxtaposed; they still have a degree of freedom in flexion along an axis perpendicular to the longitudinal members 6 and parallel to the longitudinal axis of the slats 4, 4 '(also parallel to the axis 7'), allowing the support elements 5, 5 ' juxtaposed to rotate relative to each other.

On a représenté sur la figure 2 un module de base du dispositif de couchage selon l'invention comprenant :

  • trois lattes 4, constituant des moyens de soutien dits « latéraux », dont les extrémités sont équipées d'éléments supports 5 montés pivotants sur les longerons 6 autour de l'axe 7', (la possibilité de pivotement correspondante est illustrée par la flèche double au-dessus du pivot 7), et
  • deux lattes complémentaires 4', interposées chacune entre deux lattes 4, dont les extrémités sont équipées d'éléments supports 5' solidarisées avec lesdits éléments supports « fixes » 5 (et portées par ces derniers) par l'intermédiaire des organes élastiques 8.
We have shown on the figure 2 a basic module of the coating device according to the invention comprising:
  • three slats 4, constituting so-called "lateral" support means, the ends of which are equipped with support members 5 pivotally mounted on the longitudinal members 6 around the axis 7 ', (the corresponding pivoting possibility is illustrated by the double arrow above the pivot 7), and
  • two complementary slats 4 ', each interposed between two slats 4, whose ends are equipped with support members 5' secured to said "fixed" support members 5 (and carried by the latter) via the elastic members 8.

Comme indiqué précédemment, plusieurs lattes 4' avec éléments supports 5' peuvent être prévues entre deux lattes latérales 4, suspendues au moyen d'organes élastiques 8.As indicated above, several slats 4 'with support elements 5' can be provided between two lateral slats 4, suspended by means of elastic members 8.

On comprend qu'un appui vers le bas sur une latte 4' provoque le basculement des éléments supports 5 autour de leur axe 7', dans le sens du rapprochement des deux lattes latérales 4, ce basculement étant susceptible de tendre à faire remonter les lattes 4' avec éléments supports 5' qui seraient situées juste de l'autre côté des supports 5 (raccordées par un organe élastique 8).It is understood that downward support on a slat 4 'causes the tilting of the support elements 5 around their axis 7', in the direction of approximation of the two lateral slats 4, this tilting being likely to tend to raise the slats 4 'with support elements 5' which would be located just on the other side of the supports 5 (connected by an elastic member 8).

Un mode de réalisation possible de l'invention est illustré sur les figures 3 à 6, sous la forme de deux éléments support pivotants 5 encadrant un élément support 5' pour latte complémentaire.One possible embodiment of the invention is illustrated on the Figures 3 to 6 , in the form of two pivotable support members 5 flanking a support member 5 'for complementary batten.

Sur ces figures, on remarque que les éléments supports 5 consistent en un corps 10 de forme générale parallélépipédique, comportant une face de dessus 10a, une face de dessous 10b, une face arrière 10c (destinée à venir en regard du longeron de sommier 6), une face avant 10d et deux faces latérales 10e et 10f.In these figures, it is noted that the support elements 5 consist of a body 10 of generally parallelepiped shape, having a top face 10a, a bottom face 10b, a rear face 10 c (intended to come next to the spar sommier 6), a front face 10 d and two side faces 10 e and 10 f .

Le corps de l'élément support 5 est muni d'un orifice cylindrique 11, d'axe 7', qui le traverse et qui débouche dans les faces arrière 10c et avant 10d.The body of the support element 5 is provided with a cylindrical orifice 11, axis 7 ', which passes through it and which opens into the rear faces 10c and before 10d .

Sa face de dessus 10a comporte des moyens 12 pour la réception et la fixation de l'extrémité d'une latte. Ces moyens de fixation 12 sont orientés dans le sens face arrière 10c-face avant 10d, et ils sont agencés de telle sorte qu'une fois la latte mise en place, son axe longitudinal s'étende parallèlement à l'axe 7'.Its top face 10 has means 12 for receiving and fixing the end of a batten. These fastening means 12 are oriented in the rear face direction 10 c -face before 10 d , and they are arranged so that once the lath is in place, its longitudinal axis extends parallel to the axis 7 ' .

Au niveau de ses faces latérales 10e et 10f, le corps 10 comporte des moyens 13 adaptés pour la fixation amovible d'un organe élastique 8. Ces moyens de fixation 13 se présentent sous la forme d'un logement comprenant des glissières ouvertes sur la face avant 10d.At its side faces 10 e and 10 f, the body 10 comprises means 13 adapted for releasable attachment of an elastic member 8. The fixing means 13 are in the form of a housing comprising open on slides the front face 10 d .

Les moyens 7 qui permettent la fixation du corps 10 sur le longeron de sommier 6 se présentent sous la forme d'un tenon cylindrique 14 apte à venir se loger dans l'orifice 11 du corps 10, du côté de sa face arrière 10c, et par son extrémité avant 14a, et dont l'extrémité arrière 14b comporte deux tétons monobloc 15 pour la fixation proprement dite sur ledit longeron de sommier 6 (qui comporte des orifices d'encastrement adaptés).The means 7 which allow the fixing of the body 10 on the bed frame spar 6 are in the form of a cylindrical stud 14 adapted to be housed in the orifice 11 of the body 10, on the side of its rear face 10c , and by its front end 14 a, and the rear end 14 b has two integral nipples 15 for attaching proper on said bed frame spar 6 (which has suitable mounting holes).

Le tenon cylindrique 14 est donc monté fixe sur le longeron de sommier et il constitue un organe pivot sur lequel le corps 10 peut pivoter ou basculer autour de l'axe 7'.The cylindrical pin 14 is fixedly mounted on the bed frame spar and constitutes a pivot member on which the body 10 can pivot or tilt around the axis 7 '.

Une vis (non représentée) avec tête ou rondelle, vient s'engager dans un orifice axial 16 ménagé dans l'extrémité libre 14a du tenon 14, au sein de l'orifice 11 et par la face avant 10d du corps 10, de manière à assurer le maintien dudit corps 10 sur ledit tenon 14.A screw (not shown) with head or washer, engages in an axial hole 16 formed in the free end 14a of the pin 14 within the aperture 11 and the front face 10 of the body 10, so as to maintain said body 10 on said post 14.

Le tenon 14 est prévu légèrement plus long que l'orifice 11 du corps 10 ; la vis de maintien est serrée et il reste un jeu fonctionnel permettant la rotation de ce corps 10 sur ledit tenon 14.The pin 14 is provided slightly longer than the orifice 11 of the body 10; the holding screw is tightened and there remains a functional clearance allowing the rotation of this body 10 on said post 14.

Pour permettre l'utilisation d'un moule de fabrication unique, les éléments supports 5' comportent un corps 10 identique à celui des éléments supports 5 décrits ci-dessus (avec moyen de fixation 12 pour une latte 4' et moyens de fixation 13 pour les organes élastiques 8) ; mais ils ne sont pas associés à un tenon de fixation 14.To allow the use of a single mold, the support elements 5 'comprise a body 10 identical to that of the support elements 5 described above (with attachment means 12 for a batten 4' and fastening means 13 for the elastic members 8); but they are not associated with a fixing stud 14.

Comme on peut le voir sur les figures 3 à 6, les organes élastiques 8 sont constitués de deux plots d'extrémités 15 et 16, entre lesquels s'étendent deux couples de bras en Vé 17, 17', et 18, 18', orientés en vis-à-vis.As can be seen on the Figures 3 to 6 , the elastic members 8 consist of two end pads 15 and 16, between which extend two pairs of V-arms 17, 17 ', and 18, 18', facing vis-à-vis.

Les deux plots d'extrémités 15 et 16 se présentent sous la forme de tenons ou de coulisseaux aptes à venir s'emboîter de manière amovible dans les logements avec glissières latérales 13 des corps 10 des éléments supports 5, 5', pour obtenir une fixation du type à encastrement.The two end pads 15 and 16 are in the form of tenons or sliders adapted to fit removably in the housings with side rails 13 of the bodies 10 of the support members 5, 5 ', to obtain a fixation of the built-in type.

Une fois les tenons 15, 16 logés dans les logements à glissières 13, un petit ergot en saillie 19 (figure 5) assure le verrouillage de la fixation ; le désemboîtement peut s'effectuer à force, par l'élasticité intrinsèque aux structures d'emboîtement.Once the tenons 15, 16 housed in the sliding housing 13, a small protruding lug 19 ( figure 5 ) locks the fastener; the de-nesting can be carried out by force, by the intrinsic elasticity to the interlocking structures.

Chacune des deux structures en Vé 17, 17', et 18, 18' est solidaire des deux tenons d'extrémités 15, 16 par l'intermédiaire d'articulations monoblocs 20, 21 ; d'autre part, les deux bras 17, 17' et 18, 18' de chaque structure en Vé sont raccordés l'un à l'autre par une articulation monobloc 22, 23.Each of the two Vee structures 17, 17 ', and 18, 18' is secured to the two end tenons 15, 16 by means of monobloc hinges 20, 21; on the other hand, the two arms 17, 17 'and 18, 18' of each V e structure are connected to each other by a one-piece hinge 22, 23.

Les articulations 20, 21, 22 et 23 sont parallèles entre elles, et, une fois l'ensemble correctement monté, elles s'étendent perpendiculairement ou sensiblement perpendiculairement à la surface de couchage S et aux axes d'articulation 7'.The joints 20, 21, 22 and 23 are parallel to each other, and once the assembly is correctly mounted, they extend perpendicularly or substantially perpendicularly to the coating surface S and the hinge pins 7 '.

On comprend que ces articulations 20, 21, 22 et 23 confèrent aux organes élastiques 8 un degré de liberté en extension/compression dans des directions parallèles à la surface de couchage S. It is understood that these joints 20, 21, 22 and 23 give the elastic members 8 a degree of freedom in extension / compression in directions parallel to the coating surface S.

D'autre part, ces organes élastiques 8 comportent encore un degré de liberté en flexion, c'est-à-dire autour d'un axe parallèle à la surface de couchage S et perpendiculaire auxdites articulations 20, 21, 22 et 23, du fait des caractéristiques d'élasticité propres à leur matériau de fabrication (ces organes élastiques 8 peuvent par exemple être obtenus par moulage de matière thermoplastique élastomère)On the other hand, these elastic members 8 further comprise a degree of freedom in flexion, that is to say around an axis parallel to the coating surface S and perpendicular to said joints 20, 21, 22 and 23, makes elasticity characteristics specific to their manufacturing material (these elastic members 8 may for example be obtained by molding thermoplastic elastomer material)

On comprend que l'on peut ainsi assembler à volonté une pluralité de corps 10, au moyen d'organes élastiques 8, pour former les éléments supports des lattes, et que certains de ces corps 10 peuvent être fixés de manière pivotante sur le longeron 6 du sommier 2 au moyen des tenons 14.It is understood that it is thus possible to assemble at will a plurality of bodies 10, by means of elastic members 8, to form the support elements of the slats, and that some of these bodies 10 can be pivotally attached to the spar 6 of the bed base 2 by means of the tenons 14.

La configuration des éléments supports est identique sur les deux longerons 6 en regard, pour la réception des lattes 4, 4'.The configuration of the support elements is identical on the two longitudinal members 6 opposite, for the reception of slats 4, 4 '.

Dans une variante de réalisation, les deux bras 17, 17' et 18, 18' de chaque couple de bras en Vé sont reliés entre eux par des moyens de rappel élastiques, de préférence monoblocs, qui tendent à les rapprocher l'un de l'autre.In an alternative embodiment, the two arms 17, 17 'and 18, 18' of each pair of Vee arms are interconnected by resilient return means, preferably monobloc, which tend to bring them closer to one another. 'other.

On a représenté sur les figures 7, 8 et 9 un sommier de type articulé 25 équipé d'un dispositif de couchage 1 formé de lattes parallèles 4, 4' supportées par des éléments supports 5, 5' conformes à ceux décrits ci-dessus en relation avec les figures 3 à 6.We have shown on Figures 7, 8 and 9 an articulated bed base 25 equipped with a coating device 1 formed of parallel slats 4, 4 'supported by support elements 5, 5' in accordance with those described above in connection with the Figures 3 to 6 .

On remarque les lattes 4 de tête et de pied de sommier, montées sur des éléments supports 5 fixés sur les longerons 6 en regard (au moyen des tenons 14). On remarque encore, entre ces deux lattes d'extrémités, la juxtaposition de lattes 4, 4', soit montées sur des éléments supports 5 fixés de manière pivotante sur les longerons de sommiers 6, soit montées « suspendues » sur des éléments supports 5'.We notice the slats 4 head and foot bed base, mounted on support elements 5 fixed on the side rails 6 facing (by means of the pins 14). It is still noticeable, between these two end slats, the juxtaposition of slats 4, 4 ', or mounted on support members 5 pivotally attached to the stringers of sommiers 6, or mounted "suspended" on support members 5' .

Tous les éléments 5, 5' juxtaposés sont solidarisés entre eux par des organes élastiques 8.All the elements 5, 5 'juxtaposed are joined together by elastic members 8.

Le châssis de sommier 2 comprend ici trois éléments mobiles articulés, aptes à pivoter ou à s'écarter l'un par rapport à l'autre, à savoir :

  • un élément de tête 26, - un élément central 27, et - un élément de pied 28. De plus, une ou plusieurs lattes 4' « suspendues », montée(s) sur des éléments supports 4' non directement fixées sur les longerons 6, sont prévues au niveau des zones de juxtaposition de deux éléments mobiles l'un par rapport à l'autre 26, 27 et 27, 28.
De la sorte, et du fait de la solidarisation des différents éléments supports 5, 5' par les organes élastiques 8, les lattes suspendues 4' situées dans lesdites zones de juxtaposition se répartissent de manière homogène entre elles ou entre les lattes fixes 4, lors des mouvements desdits éléments mobiles 26, 27 et 28.
Cela limite la formation d'espaces importants entre les lattes 4, 4' qui peuvent être source d'inconfort pour l'utilisateur ; et cela permet aussi d'adoucir les courbures dans les zones de juxtaposition correspondantes.The bed frame 2 here comprises three articulated movable elements, able to pivot or to deviate with respect to each other, namely:
  • a head member 26, - a central member 27, and - a foot member 28. In addition, one or more slats 4 '"suspended" mounted (s) on support members 4' not directly attached to the longitudinal members 6 , are provided at the juxtaposition zones of two movable elements relative to each other 26, 27 and 27, 28.
In this way, and because of the securing of the various support elements 5, 5 'by the elastic members 8, the suspended slats 4' located in said juxtaposition zones are distributed homogeneously between them or between the fixed slats 4, when movements of said movable elements 26, 27 and 28.
This limits the formation of large spaces between the slats 4, 4 'which can be a source of discomfort for the user; and this also makes it possible to soften the curvatures in the corresponding juxtaposition zones.

Dans un tel sommier articulé, lorsque certains des éléments mobiles sont relevés, la surface de couchage S n'est pas horizontale ; elle présente des courbures et est constituée de la juxtaposition des différentes faces d'appui supérieures des lattes 4, 4'In such an articulated bed base, when some of the movable elements are raised, the sleeping surface S is not horizontal; it has curvatures and consists of the juxtaposition of the different upper support faces of the slats 4, 4 '

Dans une variante de réalisation, les organes élastiques 8 peuvent être réalisés monoblocs (ou d'un seul tenant) avec les éléments supports associés 5, 5'.In an alternative embodiment, the elastic members 8 may be made in one piece (or in one piece) with the associated support members 5, 5 '.

La présente invention peut aussi s'appliquer à un dispositif d'assise (siège, fauteuil, banquette ...), en vue d'améliorer le confort d'assise de l'utilisateur.The present invention can also be applied to a seating device (seat, chair, bench, etc.), in order to improve the sitting comfort of the user.

De la même manière, la présente invention peut être appliquée à d'autres types de moyens de soutien corporel que des lattes ; les éléments supports 5, 5' peuvent par exemple être utilisés pour le soutien de traverses équipées de plateaux supports.In the same way, the present invention can be applied to other types of body support means than slats; the support elements 5, 5 'can for example be used for the support of sleepers equipped with support trays.
