Description

La présente invention concerne le domaine de l'ameuble­ment et plus particulièrement un canapé convertible en lit, qui peut également, en réduction, constituer un jouet.The present invention relates to the field of furniture and more particularly a sofa convertible into a bed, which can also, in reduction, constitute a toy.

Parmi les divers canapés convertibles en lits actuel­lement connus, un premier type comprend deux parties, dont l'une est la partie horizontale qui forme l'assise en position canapé et l'autre est la partie verticale qui forme le dossier en position canapé. Un second type comprend trois parties, la première partie étant constituée par le dossier, la deuxième par l'assise et la troisième étant repliée sur l'assise ou derrière le dossier. Selon un troisième type de canapé convertible en lit, une structure en trois parties est repliée dans l'assise d'un canapé qui est en quelque sorte un coffre contenant ces éléments repliés.Among the various sofas convertible into beds currently known, a first type comprises two parts, one of which is the horizontal part which forms the seat in the sofa position and the other is the vertical part which forms the backrest in the sofa position. A second type comprises three parts, the first part being constituted by the back, the second by the seat and the third being folded over the seat or behind the back. According to a third type of sofa convertible into a bed, a three-part structure is folded into the seat of a sofa which is in a way a chest containing these folded elements.

Tous ces canapés convertibles en lits de l'art antérieur sont à structure mécanique rigide relativement complexe, susceptible de se coincer ou de blesser les personnes les manipulant. D'autre part, dans la plupart de ces systèmes, les supports de l'assise sont les mêmes que les supports du couchage et l'assise se trouve donc être complètement plate puisque le couchage doit l'être. C'est là une position d'assise peu confortable. En outre, dans la pratique, il s'avère que tous ces canapés lits sont relativement lourds.All these sofas convertible into beds of the prior art have a relatively complex rigid mechanical structure, capable of getting caught or injuring the people handling them. On the other hand, in most of these systems, the seat supports are the same as the bed supports and the seat is therefore to be completely flat since the bed must be. This is an uncomfortable sitting position. In addition, in practice, it turns out that all these sofa beds are relatively heavy.

D'autre part, bien souvent un canapé lit est un meuble qui est principalement utilisé en canapé et exceptionnellement en lit.On the other hand, very often a sofa bed is a piece of furniture that is mainly used as a sofa and exceptionally as a bed.

Un object de la présente invention est de fournir un canapé convertible en lit de structure particulièrement légère, simple à manipuler et confortable notamment en position canapé.An object of the present invention is to provide a sofa convertible into a particularly light structure bed, simple to handle and comfortable especially in the sofa position.

Le canapé convertible en lit selon la présente invention comprend un socle présentant deux flancs opposés entre lesquels s'étend une tige longitudinale supérieure et une toile ou équivalent passant au-dessus de cette tige et mobile transversalement à cette dernière entre deux positions extrèmes, les bords longitudinaux opposés de cette toile étant, dans une première position, maintenus de manière à former une assise en avant de ladite tige longitudinale supérieure et ladite toile pouvant être déplacée en passant au-dessus et au-dessous de ladite tige pour être amenée dans une deuxième position, allongée, pour former un lit en avant de ladite tige longitudinale supérieure, et réciproquement.The sofa convertible into a bed according to the present invention comprises a base having two opposite sides between which extends an upper longitudinal rod and a fabric or equivalent passing over this rod and movable transversely to the latter between two extreme positions, the edges opposite longitudinal of this fabric being, in a first position, held so as to form a seat in front of said upper longitudinal rod and said fabric being movable by passing over it and below said rod to be brought into a second, elongated position, to form a bed in front of said upper longitudinal rod, and vice versa.

Selon la présente invention, les bords longitudinaux opposés de ladite toile portent, de préférence, respectivement une tige longitudinale, des moyens étant prévus pour maintenir les extrémités de ces tiges lorsque ladite toile est à sa première position.According to the present invention, the opposite longitudinal edges of said fabric preferably carry a longitudinal rod, respectively, means being provided for holding the ends of these rods when said fabric is in its first position.

Conformément à la présente invention et afin de faci­liter le mouvement de ladite toile, des moyens sont de préférence prévus pour guider les extrémités de la tige longitudinale associée au bord longitudinal avant de ladite toile, lorsque cette toile passe de sa première position à sa deuxième position, et récipro­quement.In accordance with the present invention and in order to facilitate the movement of said fabric, means are preferably provided for guiding the ends of the longitudinal rod associated with the front longitudinal edge of said fabric, when this fabric passes from its first position to its second position , and reciprocally.

Dans une variante de réalisation, le canapé convertible en lit selon la présente invention comprend un cadre fixe formant ledit socle et comprenant, vers l'arrière et vers le haut, ladite tige longitudinale supérieure, un cadre mobile entre deux positions extrèmes et monté à pivotement sur les flancs opposés du cadre fixe, parallèlement à ladite tige longitudinale supérieure, le bord avant de ladite toile étant fixé, parallèlement à ladite tige longitudinale supérieure, au cadre mobile, de façon éloignée des moyens d'articulation de ce cadre mobile sur le cadre fixe, le bord arrière de ladite toile pouvant être bloqué contre l'un desdits cadres lorsque cette toile est à sa première position. En parti­culier, le bord avant de ladite toile est situé en avant de ces moyens d'articulation lorsque cette toile est dans sa première position et est en arrière de ces moyens d'articulation lorsque ladite toile est à sa deuxième position.In an alternative embodiment, the sofa convertible into a bed according to the present invention comprises a fixed frame forming said base and comprising, towards the rear and upwards, said upper longitudinal rod, a frame movable between two extreme positions and pivotally mounted on the opposite sides of the fixed frame, parallel to said upper longitudinal rod, the front edge of said fabric being fixed, parallel to said upper longitudinal rod, to the mobile frame, away from the means of articulation of this mobile frame on the frame fixed, the rear edge of said fabric being able to be locked against one of said frames when this fabric is in its first position. In particular, the front edge of said fabric is located in front of these articulation means when this fabric is in its first position and is behind these articulation means when said fabric is in its second position.

Dans cette variante, il peut être avantageux que le cadre mobile comporte un moyen de blocage de la tige longitudinale associée au bord longitudinal arrière de ladite toile, formé de façon à pouvoir entraîner ladite tige lorsque ce cadre pivote de sa première position à sa deuxième position et permettant le retrait de celle-ci notamment lorsque le cadre se trouve dans une position intermédiaire.In this variant, it may be advantageous for the movable frame to comprise a means for blocking the longitudinal rod associated with the rear longitudinal edge of said fabric, formed so as to be able to drive said rod when this frame pivots from its first position to its second position. and allowing the withdrawal thereof in particular when the frame is in an intermediate position.

Dans une autre variante du canapé convertible en lit selon la présente invention, les flancs opposés dudit socle compren­nent respectivement une rampe ou une rainure dans lesquelles peuvent coulisser les extrémités de la tige longitudinale associée au bord longitudinal avant de ladite toile, lorsque ladite toile passe de sa première position à sa deuxième position, et réciproquement.In another variant of the sofa convertible into a bed according to the present invention, the opposite sides of said base respectively comprise a ramp or a groove in which the ends of the longitudinal rod associated with the front longitudinal edge of said fabric can slide, when said fabric passes from its first position to its second position, and vice versa.

Selon la présente invention, lesdites rainures ou rampes peuvent avantageusement passer au-dessus de ladite tige longitudinale supérieure et s'étendre vers l'avant de manière inclinée vers le sol et, en arrière de cette tige, vers le bas, les extrémités de ces rainures ou rampes constituant de préférence des butées d'extrémité pour ladite tige longitudinale avant.According to the present invention, said grooves or ramps can advantageously pass over said upper longitudinal rod and extend forwardly inclined towards the ground and, behind this rod, downward, the ends of these grooves or ramps preferably constituting end stops for said front longitudinal rod.

Le socle du canapé convertible en lit selon la présente invention peut en outre comprendre une tige longitudinale inférieure située en-dessous de ladite tige longitudinale supérieure, ladite toile passant sous et en arrière de cette tige longitudinale inférieure.The base of the sofa convertible into a bed according to the present invention may further comprise a lower longitudinal rod situated below said upper longitudinal rod, said fabric passing under and behind this lower longitudinal rod.

Dans une variante, ladite toile peut avantageusement être aménagée sous forme d'un matelas présentant des parties longitu­dinales creuses ou affaiblies permettant sa déformation lors de son mouvement autour de ladite tige longitudinale supérieure, et éventuellement autour de ladite tige longitudinale inférieure, et lorsqu'elle forme une assise en avant de ladite tige longitudinale supérieure.In a variant, said fabric can advantageously be arranged in the form of a mattress having hollow or weakened longitudinal parts allowing its deformation during its movement around said upper longitudinal rod, and possibly around said lower longitudinal rod, and when forms a seat in front of said upper longitudinal rod.

Le cadre fixe comprend des moyens pour soutenir des articulations latérales 3 sur lesquelles vient s'articuler longitudinalement le cadre mobile 2, une tige longitu­dinale supérieure 4 disposée vers l'arrière de ce bâti et éventuel­lement une tige longitudinale inférieure 5 disposée vers l'arrière de ce bâti en dessous de la tige 4. Dans la pratique, ce cadre pourra être constitué de deux flancs latéraux, visibles sur la figure 3, servant de supports aux tiges 4 et 5 qui les relient entre eux ; dans ces flancs sont ménagées les articulations 3, par exemple des ouvertures en face desquelles viennent se placer des ouvertures du cadre mobile et des axes venant solidariser de façon articulée le cadre mobile et le cadre fixe. Dans le bâti fixe, d'autres barres pourront également être prévues pour relier les deux flancs latéraux susmentionnés. Ces flancs latéraux pourront être de toute forme adaptée, pour satisfaire à des exigences particu­lières de style et de décoration.Referring to Figures 1 to 7, we will describe the first sofa convertible into a bed shown. This sofa comprises a fixed frame or frame 1 resting on a floor and a mobile frame or frame 2 articulated on the fixed frame. The fixed frame comprises means for supporting lateral articulations 3 on which the movable frame 2 is articulated longitudinally, an upper longitudinal rod 4 disposed towards the rear of this frame and possibly a lower longitudinal rod 5 arranged towards the rear of this frame below the rod 4. In practice, this frame may consist of two lateral flanks, visible in FIG. 3, serving as supports for the rods 4 and 5 which connect them together; in these flanks are formed the joints 3, for example openings in front of which are placed openings of the movable frame and pins coming to join in an articulated manner the movable frame and the fixed frame. In the fixed frame, other bars may also be provided to connect the two side flanks mentioned above. These lateral flanks can be of any suitable shape, to meet particular requirements of style and decoration.

Le cadre mobile 2 porte essentiellement une tige longi­tudinale 6 parallèle aux tiges 4 et 5 et à la ligne reliant les articulations 3. Le cadre mobile comprend également des moyens, tels que des pieds 7 pour maintenir la tige 6 à une certaine hauteur au-dessus du sol en position canapé. Enfin, des moyens de blocage 8 dont l'objet sera exposé ci-après peuvent également être prévus sur le cadre mobile 2. Comme le précédent, ce cadre pourra comprendre essentiellement des flancs latéraux de style choisi reliés par la tige 6 et éventuellement d'autres tiges, ces flancs latéraux étant à l'extérieur des flancs latéraux du cadre fixe 1.The movable frame 2 essentially carries a longitudinal rod 6 parallel to the rods 4 and 5 and to the line connecting the articulations 3. The mobile frame also includes means, such as feet 7 for holding the rod 6 at a certain height above from the floor in sofa position. Finally, blocking means 8, the object of which will be explained below, can also be provided on the mobile frame 2. Like the previous one, this frame may include essentially lateral flanks of the chosen style connected by the rod 6 and possibly other rods, these lateral flanks being outside the lateral flanks of the fixed frame 1.

Cette toile est amenée à passer au-dessus et derrière la tige 4, derrière et en-dessous de la tige 5, et son bord arrière, normalement libre est bloqué en position canapé à l'un des deux cadres. Dans le mode de réalisation représenté, une tige longitudinale 13 est fixée au bord arrière 12 de la toile 10 et cette tige 13 vient se loger dans les moyens de blocage en encoches 8 du cadre mobile 2.A canvas 10 is fixed by its front edge 11 to the rod 6 or rests on this rod and is fixed to another rod or another element of the movable frame 2. This canvas is caused to pass above and behind the rod 4, behind and below the rod 5, and its rear edge, normally free, is locked in the sofa position in one of the two frames. In the embodiment shown, a longitudinal rod 13 is fixed to the rear edge 12 of the fabric 10 and this rod 13 is housed in the notch locking means 8 of the movable frame 2.

La figure 2 représente le canapé convertible en lit de la figure 1 en position lit, la tige inférieure 5 n'ayant pas été représentée pour faciliter la compréhension de cette figure. En position lit, le cadre mobile 2 est amené à pivoter autour de l'articulation longitudinale 3 de sorte que la tige 6 portant le bord avant de la toile 10 et entraînée par pivotement au-dessus et derrière la tige supérieure 4 jusqu'à reposer pratiquement sur le sol. Pendent ce temps, le bord arrière de la toile 10 est tiré vers l'avant et l'ensemble de la toile 10 repose sur le sol pour former un support de couchage.FIG. 2 represents the sofa convertible into a bed of FIG. 1 in the bed position, the lower rod 5 not having been shown to facilitate understanding of this figure. In the bed position, the movable frame 2 is made to pivot around the longitudinal articulation 3 so that the rod 6 carrying the front edge of the fabric 10 and pivotally driven above and behind the upper rod 4 until it rests practically on the ground. During this time, the rear edge of the fabric 10 is pulled forward and the assembly of the fabric 10 rests on the ground to form a sleeping support.

On va maintenant décrire comment fonctionne et comment peut être utilisé le canapé convertible en lit précité.We will now describe how it works and how the sofa can be used as a bed.

La figure 3 représente une vue de côté dans une position canapé identique à celle de la figure 1, dans lesquelles le bâti mobile 2 est, vers l'avant, en appui sur le sol.FIG. 3 represents a side view in a sofa position identical to that of FIG. 1, in which the movable frame 2 is, towards the front, bearing on the ground.

Pour passer en position lit, l'utilisateur prend la tige 6 ou une autre partie du cadre mobile 2 et la soulève jusqu'à arriver sensiblement à la position de la figure 4. Il peut alors attraper le bord arrière 12 de la toile 10 et le tirer vers l'avant tandis que le cadre articulé continue à pivoter vers l'arrière, comme cela est représenté en figure 5. Ensuite, dans la position de la figure 6, ou à une position voisine, selon la morphologie du cadre fixe 1, du cadre mobile 2 et les éléments de blocage prévus entre eux, le cadre mobile 2 vient se bloquer tandis que la toile 10 repose sur le sol.To switch to the bed position, the user takes the rod 6 or another part of the movable frame 2 and lifts it up to arrive substantially at the position of FIG. 4. He can then catch the rear edge 12 of the fabric 10 and pull it forward while the articulated frame continues to pivot backwards, as shown in Figure 5. Then, in the position of Figure 6, or to a neighboring position, depending on the morphology of the fixed frame 1 , the movable frame 2 and the locking elements provided therebetween, the movable frame 2 is blocked while the fabric 10 rests on the ground.

La figure 7 représente une position intermédiaire du canapé convertible en lit, tandis que l'on a essayé de passer de la position de la figure 6 à celle de la figure 3 en faisant basculer le cadre mobile 2 en sens inverse. Au moment où le cadre mobile 2 est ramené vers sa position canapé, avec ses pieds 7 sur le sol, la toile n'est pas engagée dans l'élément de blocage 8. Mais le seul fait de s'asseoir ou d'appuyer sur la toile vient la mettre en position de blocage du moment que, comme cela est représenté, les moyens de blocage 8 ont été convenablement conformés.Figure 7 shows an intermediate position of the sofa convertible into a bed, while an attempt has been made to move from the position of Figure 6 to that of Figure 3 by tilting the movable frame 2 in the opposite direction. When the movable frame 2 is brought back to its sofa position, with its feet 7 on the ground, the fabric is not engaged in the locking element 8. But the mere fact of sitting or pressing the fabric puts it in the blocking position as long as, as shown, the blocking means 8 have been suitably shaped.

Le canapé convertible en lit décrit ci-dessus est susceptible de nombreuses variantes. Des rouleaux fous peuvent être montés sur les tiges 4, 5, 6 et 13 pour faciliter les mouvements de la toile. Une tige supplémentaire peut être fixée à la toile au point correspondant au fond de l'assise en position canapé, des moyens de blocage étant prévus dans l'un des deux cadres pour bloquer la toile en position canapé et raidir l'assise. Les dimensions de la toile et les divers éléments la soutenant peuvent être choisies pour que, en position lit, la dimension de la toile formant matelas posée sur le sol permette un couchage double ou simple, parallèle ou perpendiculaire au canapé. Ces dimensions peuvent également être adaptées à des adultes, des enfants ou à des jouets. Un sommier extra plat composé de lattes minces peut être prévu et comprendre une rangée de lattes fixées à l'arrière du cadre fixe 1, allant jusqu'à l'avant du cadre mobile 2 et ayant des lumières dans lesquelles coulisse une autre rangée de lattes qui elles aussi présentent des lumières dans lesquelles coulisse une troisième rangée de lattes jointes à la tige 13 de l'arrière du matelas. En position lit, ces lattes s'étalent en suivant le trajet de la tige 13. Quand on revient en position canapé, les lattes coulissent vers l'arrière, la tige 13 ramenant la troisième puis la seconde rangée de lattes. Ainsi, toutes les lattes se rangent sous le canapé. On aurait aussi pu prévoir que le sommier à lattes minces soit enroulé autour d'un moyeu enrouleur. La partie surface de couchage est constituée d'un matelas mince couvert d'un drap et d'un autre drap et d'une couverture couvrant l'ensemble et reliée à l'avant et à l'arrière par des fermetures à glissières ou autres. Les bords de la couverture peuvent être bordés sous le matelas ou être joints par des fermetures à glissières ou autres pour maintenir en place les draps et le matelas durant les mouvements de transformation de canapé en lit et vice-versa. Des ressorts peuvent joindre le cadre mobile au cadre fixe pour aider à soulever le matelas durant la transformation du canapé en lit et vice-versa.The sofa convertible into a bed described above is susceptible to many variations. Crazy rollers can be mounted on rods 4, 5, 6 and 13 to facilitate movement of the canvas. An additional rod can be attached to the canvas at the point corresponding to the bottom of the seat in the sofa position, blocking means being provided in one of the two frames to block the canvas in the sofa position and stiffen the seat. The dimensions of the fabric and the various supporting elements can be chosen so that, in the bed position, the size of the fabric forming the mattress placed on the floor allows a double or single bed, parallel or perpendicular to the sofa. These dimensions can also be adapted to adults, children or toys. An extra flat bed base made up of thin slats can be provided and comprise a row of slats fixed to the rear of the fixed frame 1, going up to the front of the movable frame 2 and having lights in which another row of slats slides. which also have lights in which slides a third row of slats joined to the rod 13 of the rear of the mattress. In the bed position, these slats spread out following the path of the rod 13. When we return to the sofa position, the slats slide backwards, the rod 13 bringing the third then the second row of slats. Thus, all the slats are stored under the sofa. One could also have foreseen that the thin slatted bed base is wound around a winding hub. The sleeping surface part consists of a thin mattress covered with a sheet and another sheet and a cover covering the whole and connected at the front and at the back by zippers or the like. . The edges of the blanket can be bordered under the mattress or be joined by zippers or the like to hold the sheets and the mattress in place during the transformation from sofa to bed and vice versa. Springs can join the movable frame to the fixed frame to help lift the mattress during the transformation of the sofa into a bed and vice versa.

On va maintenant décrire le canapé convertible en lit représenté sur les figures 8 à 10. Ce canapé convertible en lit comprend un châssis 15 reposant sur le sol et comprenant deux flancs parallèles opposés 15a, 15b reliés entre eux par une tige longitudinale supérieure 17, une tige longitudinale inférieure 18 et une tige longitudinale de renfort 27. Deux rouleaux fous 25 et 26 entourent respectivement les tiges 17 et 18. Dans ce châssis fixe sont aménagées des fentes, rainures ou lumières 16 qui vont servir à guider la toile 21. Les rainures 16 s'étendent au-dessus de la tige 17 et se prolongent vers l'avant en étant inclinées vers le bas et se prolongent verticalement et vers le bas en arrière de la tige 17.We will now describe the sofa convertible into a bed shown in FIGS. 8 to 10. This sofa convertible into a bed comprises a frame 15 resting on the ground and comprising two opposite parallel sides 15 a , 15 b connected to each other by an upper longitudinal rod 17 , a lower longitudinal rod 18 and a longitudinal reinforcing rod 27. Two idler rollers 25 and 26 respectively surround the rods 17 and 18. In this fixed frame are provided slots, grooves or slots 16 which will serve to guide the fabric 21. The grooves 16 extend above the rod 17 and extend forward by being inclined downward and extend vertically and downwards behind the rod 17.

Le bord avant 22 de la toile 21 entoure une tige longi­tudinale 19. Cette tige repose, à hauteur d'assise, sur l'extrémité avant de la rainure 16 et lui sert de butée de fin de course 28.The front edge 22 of the fabric 21 surrounds a longitudinal rod 19. This rod rests, at seat height, on the front end of the groove 16 and serves as its end of travel stop 28.

La toile 21 contourne le rouleau fou 25 puis le rouleau fou 26. Son bord arrière 23 est fixé à une tige longitudinale arrière 24 dont les extrémités s'étendent en avant des flancs 25a et 15b du châssis 15. Lorsqu'on s'assoit sur le canapé, entre la tige avant 19 et la tige supérieure 17, la tige avant 19 vient en butée contre les extrémités avant 28 des rainures 16 et la tige arrière 24 bute contre la butée 20 prévue sur le châssis 15, près du sol, et orientée vers l'avant et retient la toile 15 en position canapé.The sheet 21 passes the idler roller 25 and the roller mad 26. Its rear edge 23 is fixed to a rear longitudinal rod 24 whose ends extend forwardly of the sidewalls 25 a and 15 b of the frame 15. When s' sits on the sofa, between the front rod 19 and the upper rod 17, the front rod 19 abuts against the front ends 28 of the grooves 16 and the rear rod 24 abuts against the stop 20 provided on the chassis 15, close to the ground , and oriented towards the front and retains the fabric 15 in the sofa position.

Sur la figure 9, la tige 19 du bord avant 22 de la toile 21 est représentée dans sa position la plus haute au-dessus de la tige horizontale supérieure 17 et du rouleau fou 25 qui l'entoure. Ce premier bord est dans la rainure 16 sur chacun des flancs 15a et 15b du châssis 15. Cette rainure est amplement plus large que le diamètre de la tige 19. La tige 19 sort des deux côtés des flancs 15a et 15b.In Figure 9, the rod 19 of the front edge 22 of the fabric 21 is shown in its highest position above the upper horizontal rod 17 and the idler roller 25 which surrounds it. This first edge is in the groove 16 on each of the sides 15 a and 15 b of the frame 15. This groove is much wider than the diameter of the rod 19. The rod 19 comes out on both sides of the sides 15 a and 15 b .

Pour convertir le canapé de la figure 8 en lit de la figure 10, l'utilisateur prend le second bord 23 de la toile 21 et le tire vers l'avant. La toile se tend et entraine vers l'arrière la première tige 19 dans les coulisses ou rainures 16. En fin de course, la toile 21 est étalée sur le sol.To convert the sofa of Figure 8 to the bed of Figure 10, the user takes the second edge 23 of the fabric 21 and pulls it forward. The fabric stretches and drives the first rod 19 backwards in the slides or grooves 16. At the end of the race, the fabric 21 is spread over the ground.

La figure 10 montre la toile 21 étalée sur le sol avec sa face de couchage 21a exposée vers le haut. La tige avant 19 de la toile 21 repose contre l'extrémité 29 dans la partie verticale de la rainure 16.Figure 10 shows the fabric 21 spread on the floor with its coating side 21a exposed upwardly. The front rod 19 of the fabric 21 rests against the end 29 in the vertical part of the groove 16.

Pour ramener la toile 21 en position canapé, deux personnes prennent chacune d'un côté les extrémités de la tige 19 de la toile 21 et la ramènent dans les rainures 16, jusqu'à leurs extrémités avant formant les butées 28.To bring the fabric 21 back to the sofa position, two people each take the ends of the rod 19 of the fabric 21 on one side and bring it back into the grooves 16, up to their front ends forming the stops 28.

La toile est dans une position similaire à celle repré­sentée dans la figure 7. Il suffit de pousser ou de s'asseoir sur la toile, entre la tige avant 19 et la tige supérieure 17, pour que la seconde tige 24 de la toile 21 vienne buter contre la butée 20 du châssis et maintienne la face d'assise 21b en position canapé.The fabric is in a position similar to that shown in Figure 7. Just push or sit on the fabric, between the front rod 19 and the upper rod 17, so that the second rod 24 of the canvas 21 comes abut against the stop 20 of the chassis and maintain the seat face 21 b in the sofa position.

On voit sur la figure 8 que la toile 21 est aménagée sous forme d'un matelas qui comprend des parties longitudinales en saillie de telle sorte que le matelas peut se déformer lorsqu'il contourne les tiges longitudinales 17 et 18 et lorsqu'il se courbe pour former l'assise en avant de la tige longitudinale 17.It can be seen in FIG. 8 that the fabric 21 is arranged in the form of a mattress which includes protruding longitudinal parts so that the mattress can deform when it goes around the longitudinal rods 17 and 18 and when it bends to form the seat in front of the longitudinal rod 17.

Le second mode de réalisation décrit ci-dessus est susceptible de nombreuses variantes. En particulier, l'adaptation d'un mécanisme entraînant la première tige 22, composée de chaines et de pignons et contournant la rainure 16, est tout à fait possible. La rainure 16 et la tige 19 pourraient être substituées par une rampe et des anneaux coulissants dessus. Les dimensions de la toile peuvent être adaptées à des adultes ou des enfants ou même à des jouets. Un sommier extra plat pourrait être prévu et se ranger en accordéon sous le matelas.The second embodiment described above is susceptible of numerous variants. In particular, the adaptation of a mechanism driving the first rod 22, composed of chains and sprockets and bypassing the groove 16, is entirely possible. The groove 16 and the rod 19 could be replaced by a ramp and sliding rings on it. The dimensions of the canvas can be adapted to adults or children or even to toys. An extra flat base could be provided and can be arranged in an accordion under the mattress.

La présente invention ne se limite évidemment pas aux exemples ci-dessus décrits. Bien d'autres variantes de réali­sation sont possibles sans sortir du cadre défini par les revendi­cations annexées.The present invention is obviously not limited to the examples described above. Many other alternative embodiments are possible without departing from the scope defined by the appended claims.
