Description

AGENCEMENT D'ASSISE MODULABLE D'UN SIEGE TRANSFORMABLE EN COUCHAGE ET ELEMENT MEUBLANT OBTENUMODULAR SEAT ARRANGEMENT OF A SEAT CONVERTIBLE INTO A BED AND FURNISHING ELEMENT OBTAINED
La présente invention concerne un agencement d'assise modulable d'un siège transformable, notamment pour former un siège à assise courte, un siège à assise longue et un couchage intégral. L'invention couvre aussi l'élément meublant obtenu. On connaît le brevet allemand DE 15 29 560 qui décrit une structure télescopique qui assure une variation de la longueur d'assise en vue de la réalisation d'un lit.The present invention relates to a modular seating arrangement of a transformable seat, in particular for forming a short seat, a long seat and a full bed. The invention also covers the furnishing element obtained. We know the German patent DE 15 29 560 which describes a telescopic structure which ensures a variation of the seat length for the production of a bed.
Ce brevet décrit de nombreuses variantes de réalisation des parties coulissantes et des glissières nécessaires sans pour autant résoudre les problèmes posés par un tel agencement modulable.This patent describes numerous alternative embodiments of the sliding parts and of the slides required without, however, solving the problems posed by such a modular arrangement.
En effet, dans le cas d'un siège transformable, le matelas est intégré car il faut éviter tout apport postérieur d'un matelas indépendant. On perdrait alors les avantages liés au siège transformable et l'on se trouverait hors de l'invention. Un tel siège transformable est parfaitement décrit dans la demande de brevet français FR 01 03837, également au nom du présent déposant.Indeed, in the case of a convertible seat, the mattress is integrated because it is necessary to avoid any later contribution of an independent mattress. We would then lose the advantages associated with the convertible seat and we would be outside the invention. Such a convertible seat is perfectly described in French patent application FR 01 03837, also in the name of the present applicant.
Il comprend un châssis dont les montants sont télescopiques, des lattes formant sommier de l'assise comme du siège et un matelas constituant la garniture de l'assise du siège et le matelas du lit après transformation en position couchage. Un premier problème est celui de contraindre le matelas à prendre le pliage adapté lors du passage de la position couchage à la position siège.It includes a frame whose uprights are telescopic, slats forming the bed base of the seat as well as the seat and a mattress constituting the lining of the seat seat and the bed mattress after transformation into the sleeping position. A first problem is that of forcing the mattress to take the appropriate folding when passing from the sleeping position to the seat position.
Un deuxième problème est celui des lattes qui coulissent dans les montants télescopiques et dont les extrémités sont positionnées dans des rainures desdits montants. Il est prévu des embouts et des liens de traction des lattes mais celles-ci peuvent avoir une tendance à se positionner en travers lors des manœuvres de translation, avant tension des liens, ce qui n'est pas satisfaisant. De plus, il faut pouvoir solidariser le matelas au châssis, à son extrémité pour que celui-ci reste solidaire du châssis durant les manoeuvres de repliement, ce qui est un autre problème.A second problem is that of the slats which slide in the telescopic uprights and whose ends are positioned in grooves of said amounts. End caps and traction links for the slats are provided, but these may have a tendency to position themselves crosswise during translational maneuvers, before tensioning the links, which is not satisfactory. In addition, it must be possible to secure the mattress to the chassis, at its end so that the latter remains secured to the chassis during the folding maneuvers, which is another problem.
Les pieds sont également un problème notamment ceux d'extrémité car ils ne doivent pas gêner la manoeuvre tout en assurant un soutien efficace en position couchage de ce châssis. On constate que pour obtenir un produit parfaitement adapté, qui fonctionne dans tous les cas, bien que le produit paraisse simple, il faut résoudre plusieurs problèmes.The feet are also a problem especially those at the end because they must not interfere with the maneuver while ensuring effective support in the lying position of this chassis. We note that to obtain a perfectly adapted product, which works in all cases, although the product seems simple, it is necessary to solve several problems.
La présente invention répond à ces contraintes par un agencement perfectionné d'assise modulable d'un siège transformable en un couchage. A cet effet, l'agencement d'assise modulable d'un siège transformable, notamment pour former un siège à assise courte, un siège à assise longue et un couchage intégral comprenant un châssis avec des paires de montants télescopiques, des lattes disposées entre ces montants surmontées d'un matelas et des moyens de liaison de ces lattes les unes aux autres, se caractérise en ce qu'il comprend des moyens d'assujettissement du matelas sur l'extrémité libre du châssis.The present invention meets these constraints by an improved modular seating arrangement of a seat convertible into a bed. To this end, the modular seating arrangement of a convertible seat, in particular for forming a short seat, a long seat and a full bed comprising a frame with pairs of telescopic uprights, slats arranged between these uprights surmounted by a mattress and means for connecting these slats to each other, is characterized in that it comprises means for securing the mattress to the free end of the chassis.
Selon une autre caractéristique, une première partie de ces moyens d'assujettissement est associée à la traverse d'extrémité de la dernière paire de montants et une partie est associée au matelas. Selon un mode de réalisation, les moyens d'assujettissement comprennent une patte en fil métallique rigide, plié en U, située dans le plan de l'assise, solidaire d'une traverse d'extrémité du châssis et un manchon solidaire d'une housse du matelas, ledit manchon recevant ladite patte. L'agencement selon l'invention prévoit aussi un fourreau de réception des lattes, lui-même comportant autant de logements que de lattes ainsi que des moyens de liaison aux extrémités.According to another characteristic, a first part of these securing means is associated with the end cross member of the last pair of uprights and a part is associated with the mattress. According to one embodiment, the securing means comprise a tab made of rigid metal wire, bent in a U, situated in the plane of the seat, secured to a cross member at the end of the chassis and a sleeve secured to a cover of the mattress, said sleeve receiving said tab. The arrangement according to the invention also provides a sleeve for receiving the slats, itself comprising as many housings as slats as well as connection means at the ends.
Avantageusement, chaque logement a une longueur et une largeur sensiblement identiques à celles d'une latte.Advantageously, each housing has a length and a width substantially identical to that of a slat.
Il est aussi prévu au moins un pied escamotable solidaire des montants de la paire de montants, chaque pied comprenant un galet disposé dans le montant correspondant, un axe de rotation passant à travers la lumière, un bras solidaire de cet axe, un ergot d'appui et des moyens de blocage. Les moyens de blocage consistent en un crochet apte à coopérer avec une autre des paires de montants, ce crochet étant équipé de moyens élastiques de rappel.There is also provided at least one retractable foot integral with the uprights of the pair of uprights, each foot comprising a roller disposed in the corresponding upright, an axis of rotation passing through the lumen, an arm integral with this axis, a lug of support and blocking means. The locking means consist of a hook capable of cooperating with another of the pairs of uprights, this hook being equipped with elastic return means.
L'invention couvre aussi l'élément meublant comprenant une couette avec des • moyens de liaison adaptés permettant le pliage des pans latéraux de façon à assurer la double fonction de couvre-siège et de couette de couchage. Un mode de réalisation est maintenant décrit en détail sans qu'il soit limitatif, cette description étant faite en regard des dessins annexés qui représentent :The invention also covers the furnishing element comprising a quilt • with suitable connecting means for folding the side flaps so as to provide the dual function of seat covers and bedding duvet. An embodiment is now described in detail without being limiting, this description being made with reference to the appended drawings which represent:

Sur la figure 1 de l'art antérieur, le châssis 10 représenté comprend une assiseIn FIG. 1 of the prior art, the chassis 10 shown comprises a seat
12 et un dossier 14 formant également tête de lit.12 and a backrest 14 also forming the headboard.
L'assise 12 est transformable et composée de paires de montants 16, 18 et 20, en l'occurrence trois paires. Les montants de chaque paire, disposés d'un même cδté, sont télescopiques et montés coulissants les uns dans les autres en sorte d'autoriser la modification des dimensions longitudinales de cette assise.The seat 12 is convertible and composed of pairs of uprights 16, 18 and 20, in this case three pairs. The uprights of each pair, arranged on the same side, are telescopic and sliding mounted one inside the other so as to allow the modification of the longitudinal dimensions of this seat.
Ces montants portent chacun une fente 22 longitudinale sur la face interne, cette fente recevant les extrémités de lattes 24 formant un sommier.These uprights each carry a longitudinal slot 22 on the internal face, this slot receiving the ends of slats 24 forming a bed base.
Des entretoises 26 assurent la rigidité et la résistance mécanique dudit châssis. Des pieds 28 complètent ce châssis. Ces pieds sont solidaires des montants de façon à suivre leurs déplacements lors des différents mouvements de translation des parties coulissantes.Spacers 26 ensure the rigidity and mechanical strength of said chassis. 28 feet complete this chassis. These feet are integral with the uprights so as to follow their movements during the different translational movements of the sliding parts.
Sur la figure 2 de cet art antérieur, on constate la présence de liens 30 qui assurent une relation mécanique entre les lattes. Ainsi, lors de la traction sur l'assise pour la transformer en couchage, la première latte tracte la deuxième et les suivantes au fur et à mesure du déploiement.In Figure 2 of this prior art, there is the presence of links 30 which provide a mechanical relationship between the slats. Thus, when pulling on the seat to transform it into a bed, the first slat pulls the second and the following as it is deployed.
La figure 3, toujours concernant l'art antérieur montre l'intérêt de disposer d'une fente 22 sur la face intérieure de chaque montant puisque chaque latte, qui est bombée pour assurer un mouvement de rappel élastique, s'allonge lorsque le châssis supporte une charge.Figure 3, still relating to the prior art shows the advantage of having a slot 22 on the inner face of each upright since each slat, which is curved to ensure an elastic return movement, lengthens when the chassis supports a charge.
Il est prévu de rapporter un matelas sur ce châssis, ce matelas étant surmonté d'une couette, non représentée, qui assure la double fonction de couvre-siège et de couette de couchage. A cet effet, des moyens de liaison adaptés permettent le pliage des pans latéraux, par exemple en utilisant des pressions.It is planned to bring a mattress onto this frame, this mattress being surmounted by a duvet, not shown, which provides the dual function of seat cover and sleeping comforter. To this end, suitable connecting means allow the folding of the side panels, for example by using pressures.
Si l'on se reporte à la figure 4, le mode de réalisation selon la présente invention consiste à prévoir des moyens 32 d'assujettissement du matelas à l'extrémité libre du châssis.Referring to FIG. 4, the embodiment according to the present invention consists in providing means 32 for securing the mattress to the free end of the chassis.
A cet effet, une première partie de ces moyens est associée à la traverse 34 d'extrémité de la dernière paire 20 de montants, sous forme d'une patte 36. En l'occurrence, cette patte 36 est réalisée à partir d'un fil métallique rigide, préalablement plié en U, dont les extrémités sont liées, par exemple par soudure à ladite traverse 32 d'extrémité.To this end, a first part of these means is associated with the cross member 34 at the end of the last pair 20 of uprights, in the form of a tab 36. In this case, this tab 36 is produced from a rigid metal wire, previously bent into a U, the ends of which are linked, for example by welding to said end cross member 32.
Le fond du U de la patte en fil métallique est orienté vers le dossier.The bottom of the U of the metal wire tab is oriented towards the backrest.
En variante, la patte peut ne comprendre que deux tiges parallèles.Alternatively, the tab may comprise only two parallel rods.
Le matelas 38 est posé sur l'ensemble et selon l'invention, il est équipé avantageusement d'une housse 40 avec un manchon 42 qui constitue l'autre partie des moyens 32 d'assujettissement. Dans ce mode de réalisation, il s'agit d'une poche rapportée sur la face inférieure de la housse de ce matelas. Dans le cas où il s'agit de deux tiges, il convient de prévoir plutδt deux manchons. Le choix de la densité du matériau constituant le matelas est également d'importance puisqu'il faut qu'elle soit suffisante pour assurer le confort du couchage et de l'assise sans pour cela perturber le pliage lors du passage de l'assise de la position couchage en position siège. Il s'agit avantageusement d'une mousse à forte densité. Selon une variante, il est aussi possible de prévoir des modules articulés au nombre de trois, la housse permettant de les lier en autorisant l'articulation. Sur la figure 5A, le siège transformable a son assise en position de couchage. Le matelas 38 est dans sa housse 40 et la patte 36 est introduite dans le manchon 42. Lorsque l'utilisateur pousse la traverse 34, il repousse les montants qui pénètrent les uns dans les autres, raccourcissant la longueur de l'assise.The mattress 38 is placed on the assembly and according to the invention, it is advantageously equipped with a cover 40 with a sleeve 42 which constitutes the other part of the securing means 32. In this embodiment, it is a pocket attached to the underside of the cover of this mattress. In the case where there are two rods, it should rather provide two sleeves. The choice of the density of the material constituting the mattress is also important since it must be sufficient to ensure the comfort of the bed and the seat without disturbing the folding during the passage of the seat of the sleeping position in seat position. It is advantageously a high density foam. According to a variant, it is also possible to provide three articulated modules, the cover making it possible to link them while authorizing articulation. In FIG. 5A, the transformable seat has its seat in the sleeping position. The mattress 38 is in its cover 40 and the tab 36 is introduced into the sleeve 42. When the user pushes the cross-member 34, he pushes the uprights which penetrate into each other, shortening the length of the seat.
Le matelas 38 étant assujetti à l'extrémité du châssis, sur toute la première portion, la seule solution pour le matelas lors du raccourcissement de l'assise est de se courber comme cela est représenté sur la figure 5B.The mattress 38 being secured to the end of the frame, over the entire first portion, the only solution for the mattress when shortening the seat is to bend as shown in Figure 5B.
Comme la patte se prolonge sur une certaine longueur, dans le plan de couchage ou de l'assise, le matelas se positionne avec deux courbures 44, 46 opposées formant un S.As the leg extends over a certain length, in the sleeping or seat plane, the mattress is positioned with two opposite curves 44, 46 forming an S.
Ces deux courbures s'accentuent au fur et à mesure de la translation et du raccourcissement de l'assise pour atteindre la forme représentée de façon schématique sur la figure 5C.These two curvatures become more pronounced as the translation and the shortening of the seat to reach the shape shown schematically in Figure 5C.
Toute variante des moyens d'assujettissement comme une platine en remplacement de la patte en U ou à deux tiges, avec des pressions de fixation de la housse sur cette platine est considérée comme un équivalent technique. Dans certains cas de confort élevé, soit la densité de la mousse est forte soit l'épaisseur est important et le repliement en S est plus difficile. Afin de faciliter cette opération et que l'utilisateur ne ressente aucun inconvénient, le matelas représenté sur la figure 6 est muni de fentes 43 transversales non débouchantes, réparties dans les zones de pliage notamment. Ainsi, lorsque le matelas subit une pression de pliage, l'épaisseur du matelas au droit des fentes est réduite et la conformation de ce matelas ne pose pas de problème. Les fentes s'ouvrent sur l'extrados et se jointent sur l'intrados permettant une articulation et une souplesse. En position d'utilisation, les fentes ne sont pas ressenties et le matelas travaille sur toute son épaisseur apportant un confort sans égal, la pression du corps en position assise ou couchée étant réduite. Sur la figure 7A, on a représenté un mode de réalisation des liens 30 entre les lattes. Le mode de réalisation représenté permet de solutionner le problème de la mise en travers de ces lattes.Any variant of the securing means such as a plate in replacement of the U-shaped leg or with two rods, with pressures for fixing the cover to this plate is considered to be a technical equivalent. In some cases of high comfort, either the density of the foam is high or the thickness is important and the folding in S is more difficult. In order to facilitate this operation and so that the user does not feel any inconvenience, the mattress shown in FIG. 6 is provided with non-opening transverse slots 43, distributed in the folding zones in particular. Thus, when the mattress undergoes a folding pressure, the thickness of the mattress in line with the slots is reduced and the conformation of this mattress does not pose any problem. The slots open on the upper surface and join on the lower surface allowing articulation and flexibility. In the position of use, the slots are not felt and the mattress works over its entire thickness providing unparalleled comfort, the pressure of the body in the sitting or lying position being reduced. In FIG. 7A, an embodiment of the links 30 between the slats is shown. The embodiment shown makes it possible to solve the problem of crossing these slats.
Ce mode de réalisation consiste en un fourreau 48 réalisé à partir d'une toile de largeur sensiblement identique à celle des lattes avec des logements 50 multiples d'une longueur et d'une largeur telles qu'elles permettent de contenir dans chacun d'eux la majeure partie de la latte correspondante.This embodiment consists of a sheath 48 produced from a canvas of width substantially identical to that of the slats with housings 50 multiple of a length and a width such that they make it possible to contain in each of them. most of the corresponding slat.
Chaque latte est ainsi maintenue sensiblement parallèle à la précédente. Le degré de liberté angulaire par rapport aux montants est réduit dans tous les cas et interdit tout blocage lors du déploiement ou du repliement de l'assise.Each slat is thus kept substantially parallel to the previous one. The degree of angular freedom with respect to the uprights is reduced in all cases and prevents any blockage during deployment or folding of the seat.
Cette solution est industrielle et présente aussi l'intérêt d'être économiquement réaliste surtout que les embouts de latte peuvent être éventuellement supprimés dans ces conditions.This solution is industrial and also has the advantage of being economically realistic, especially since the batten tips can possibly be eliminated under these conditions.
Aux extrémités de ce fourreau, il est prévu des attaches 52, 54 pour solidariser les extrémités de ce fourreau d'un côté au dossier/tête de lit 14 et de l'autre côté à la traverse 34 par exemple.At the ends of this sheath, there are provided fasteners 52, 54 to secure the ends of this sheath on one side to the backrest / headboard 14 and on the other side to the cross member 34 for example.
Sur la figure 7B, on a représenté une variante de réalisation d'un fourreau 48-1 qui consiste à ménager des boutonnières 55 pour laisser passer les lattes 24. dans ce cas, les lattes 24 sont positionnées dessus/dessous suivant l'axe transversal.In FIG. 7B, an alternative embodiment of a sheath 48-1 has been shown which consists in providing buttonholes 55 to let the slats 24 pass. In this case, the slats 24 are positioned above / below along the transverse axis .
Sur les figures 8A et 8B, les pieds escamotables 56 sont solidaires des montants de la paire 20 de montants.In FIGS. 8A and 8B, the retractable feet 56 are integral with the uprights of the pair 20 of uprights.
Chaque pied 56 comprend un galet 58 monté dans le montant correspondant, l'axe 60 de rotation passant à travers la lumière 22 et un bras 62, solidaire de cet axe 60.Each leg 56 comprises a roller 58 mounted in the corresponding upright, the axis 60 of rotation passing through the lumen 22 and an arm 62, integral with this axis 60.
Le bras 62 peut ainsi pivoter librement autour de cet axe 60 et le galet peut rouler dans le montant sans pouvoir s'en extraire, son diamètre étant supérieur à la largeur de la lumière 22. Le bras porte en outre un ergot d'appui 64.The arm 62 can thus pivot freely around this axis 60 and the roller can roll in the upright without being able to extract it, its diameter being greater than the width of the lumen 22. The arm also carries a support lug 64.
Dans chaque montant, il se trouve aussi les extrémités des lattes 24> ce qui limite l'espace disponible, surtout dans la position siège avec assise réduite car les lattes se retrouvent en butée les unes contre les autres. Des moyens de blocage 66 assurent plusieurs fonctions.In each upright, there are also the ends of the slats 24 > which limits the space available, especially in the seat position with reduced seat because the slats find themselves in abutment against each other. Locking means 66 perform several functions.
Ces moyens de blocage consistent en un crochet 68 apte à coopérer avec la paireThese locking means consist of a hook 68 able to cooperate with the pair
16 de montants, plus particulièrement avec l'une de leurs entretoises 26, ce crochet étant équipé de moyens élastiques 70 de rappel.16 of uprights, more particularly with one of their spacers 26, this hook being equipped with elastic means 70 for return.
Pour compléter l'ensemble, une roue 72 est rapportée à l'extrémité du bras 62 pour des raisons de commodité de manœuvre.To complete the assembly, a wheel 72 is attached to the end of the arm 62 for reasons of convenience of operation.
Le fonctionnement de ce pied escamotable est automatique.The operation of this retractable foot is automatic.
Lorsque le siège est en position assise courte, les crochets 68 de chaque pied, sous l'action des moyens élastiques 70 de rappel, coopère avec la même entretoise 26. De ce fait, il est impossible de modifier l'allonge de l'assise et ces moyens 66 de blocage assurent le verrouillage de l'assise.When the seat is in the short sitting position, the hooks 68 of each foot, under the action of the elastic return means 70, cooperate with the same spacer 26. Therefore, it is impossible to modify the length of the seat and these blocking means 66 ensure the locking of the seat.
Lorsque l'utilisateur souhaite transformer l'assise du siège en couchage, il débloque le crochet 68 d'un des pieds, avantageusement relié à celui de l'autre pied, et chaque pied vient au contact du sol par la roue 72 disposée à son extrémité libre.When the user wishes to transform the seat of the seat into a bed, he unlocks the hook 68 of one of the feet, advantageously connected to that of the other foot, and each foot comes into contact with the ground by the wheel 72 placed at its free end.
L'utilisateur manœuvre ensuite l'assise en tirant sur la traverse d'extrémité 34.The user then maneuvers the seat by pulling on the end cross member 34.
Ceci entraîne d'ailleurs le fourreau qui se déploie et entraîne les lattes.This also drives the sheath which unfolds and drives the slats.
Dès le début de la traction, il se produit une libération d'espace puisque les lattes ne se trouvent plus juxtaposées, au moins la première latte par rapport aux autres.From the start of traction, there is a release of space since the slats are no longer juxtaposed, at least the first slat relative to the others.
De ce fait, le galet 58 peut se déplacer dans le montant et le pied est dressé jusqu'à ce que son ergot 64 vienne au contact de la face inférieure du montant, permettant un arc-boutement. g A l'inverse, lorsque l'assise est repliée, l'accumulation des lattes repousse le galet et oblige le pied à se relever et à venir se crocheter en fin de repliement.Therefore, the roller 58 can move in the upright and the foot is raised until its lug 64 comes into contact with the underside of the upright, allowing a bracing. g Conversely, when the seat is folded, the accumulation of slats repels the roller and forces the foot to rise and come to hook at the end of folding.
L'agencement selon la présente invention permet de disposer d'un châssis parfaitement fonctionnel et compatible avec une réalisation industrielle dans les meilleures conditions techniques et économiques.The arrangement according to the present invention makes it possible to have a chassis that is perfectly functional and compatible with industrial production under the best technical and economic conditions.
Selon une variante, ces deux pieds peuvent ne faire qu'une seule entité en forme de U par exemple.According to a variant, these two feet can make only one U-shaped entity for example.
De même, il est possible de prévoir un blocage dans la position d'assise courte. Similarly, it is possible to provide a blockage in the short seating position.
