La présente invention concerne un dispositif permettant de basculer le dossier d'un canapé afin de permettre sa transformation en lit par la juxtaposition du dossier et de l'assise. The present invention relates to a device for tilting the back of a sofa to allow its transformation into bed by the juxtaposition of the backrest and the seat.
Il existe un grand nombre de systèmes permettant de transformer un canapé en lit: Certains mécanismes privilégient le confort de couchage, d'autres l'esthétique, d'autre l'encombrement. 10 Le dispositif selon l'invention répond à la demande de consommateurs soucieux d'obtenir pour un même canapé, l'esthétique allégée d'un canapé "design" (dossier séparé de l'assise), un véritable lit 15 d'appoint pour 2 personnes, et un mécanisme de conversion simple et rapide. There are a large number of systems for transforming a sofa into a bed: Some mechanisms favor sleeping comfort, others aesthetics, other clutter. The device according to the invention meets the demand of consumers anxious to obtain for the same sofa, the lightened aesthetics of a sofa "design" (separate seat back), a real bed 15 extra for 2 people, and a simple and fast conversion mechanism.
Le couchage s'effectue dans le sens de la longueur. The coating is made in the direction of the length.
Il comporte selon une première caractéristique,une 20 structure d'assise sur laquelle se fixeront, au moyen d'un axe, les piétements arrières supportant le dossier. La bascule des piétements arrières sur cet axe, situé sous l'assise, permet de convertir le canapé en lit et inversement. 25 Des systèmes de butés permettent d'arrêter la course du dossier en position canapé d'une part, et lit d'autre part. It comprises according to a first feature, a 20 seat structure on which will be fixed, by means of an axis, the rear legs supporting the file. The rocking of the rear legs on this axis, located under the seat, converts the sofa bed and vice versa. Stop systems make it possible to stop the running of the backrest in the sofa position on the one hand, and on the other hand reads.
En mode lit, le mécanisme permet à assise et au dossier de se rejoindre bord à bord pour former la 30 surface de couchage. In bed mode, the mechanism allows seat and back to meet edge to edge to form the sleeping surface.
Lorsque que l'utilisateur appuie sur le dossier, celui-ci bascule en position lit; lors de cette opération, l'assise se soulève légèrement afin de 35 procurer la résistance nécessaire à un basculement accidentel. When the user presses on the backrest, it tilts to bed position; during this operation, the seat lifts slightly to provide the necessary resistance to accidental tilting.
Le dossier forme alors avec l'assise, une aire de couchage. Une buté fixé sur la structure permet de 2867367 -2- solidariser l'ensemble dossier/assise en position lit. The file then forms with the seat, a sleeping area. A stop fixed on the structure makes it possible to secure the whole backrest / seat in bed position.
Pour retrouver la position canapé, l'utilisateur soulève le dossier. Lors de cette opération, l'assise se soulève légèrement. En fin de rotation, Le 5 dossier est bloqué par des butées d'une part, par le poids de l'assise d'autre part. Le convertible retrouve sa fonction canapé. To find the sofa position, the user raises the file. During this operation, the seat lifts slightly. At the end of rotation, the file is blocked by stops on the one hand, by the weight of the seat on the other hand. The convertible finds its couch function.
Ce mécanisme permet de recouvrir une partie de l'assise (en position canapé) afin de réduire la 10 profondeur d'assise. Le dispositif bascule vers l'avant, réduisant la dimension de l'assise à une dimension ergonomique. This mechanism makes it possible to cover part of the seat (in sofa position) in order to reduce the seat depth. The device tilts forward, reducing the size of the seat to an ergonomic dimension.
Selon les modes particuliers de réalisation: 15 - L'axe de rotation peut être avancé ou reculé afin de permettre une modification des dimensions du dossier, de l'assise et/ou la largeur du canapé. According to particular embodiments: 15 - The axis of rotation can be moved forward or backward to allow a modification of the dimensions of the backrest, the seat and / or the width of the sofa.
- Le dispositif selon l'invention peut être placé de chaque coté du canapé afin de supporter des 20 accoudoirs/têtes de lit. The device according to the invention can be placed on each side of the sofa to support armrests / headboards.
- Le dispositif selon l'invention peut être installé plusieurs fois en fonction de la longueur du canapé et des matériaux utilisés pour sa réalisation. - The device according to the invention can be installed several times depending on the length of the sofa and the materials used for its realization.
- Le dispositif peut être complété de systèmes de 25 blocages ou de lestage de l'avant ou de la base du canapé, ou de piétements fixes complémentaires, ou d'aimants disposés entre la structure et l'assise, de façon à assurer une plus grande stabilité à l'ensemble. 30 Les dessins annexés illustrent l'invention: La figure 1 représente, en coupe, le dispositif de l'invention en position canapé. - The device can be supplemented with blocking systems or ballast of the front or the base of the sofa, or complementary fixed legs, or magnets arranged between the structure and the seat, so as to ensure a more great stability to the whole. The accompanying drawings illustrate the invention: Figure 1 shows, in section, the device of the invention in sofa position.
La figure 2 représente, en coupe, le dispositif en 35 position canapé et lit. Figure 2 shows, in section, the device in position sofa and bed.
La figure 3 représente, en coupe, les moments de la rotation du dossier. Pour l'exemple, le dispositif est ici appliqué à une assise et un dossier en mousse de 150 mm d'épaisseur. 40 En référence à ces dessins, le dispositif comporte: - Une pièce A (figure 1) faisant office de piètement arrière de l'assise et de support du dossier. La 5 pièce A est fixée sur la pièce B (structure du canapé) au moyen d'un axe (AB5). Quand cet axe entre en rotation, la pièce A bascule et forme avec l'assise une surface de couchage (fig. 2). Figure 3 shows, in section, the moments of the rotation of the file. For the example, the device is here applied to a seat and back made of foam 150 mm thick. Referring to these drawings, the device comprises: - A piece A (Figure 1) acting as a rear base of the seat and back support. The piece A is fixed on the piece B (structure of the sofa) by means of an axis (AB5). When this axis comes into rotation, the piece A swings and forms with the seat a sleeping surface (FIG 2).
- La forme de la pièce A permet de réaliser cette conversion et d'assurer la stabilité de l'ensemble en position canapé. 10 - Des butés permettent de bloquer la course du dossier en position canapé (A6) et lit (A7). - The shape of the part A makes it possible to achieve this conversion and to ensure the stability of the assembly in sofa position. 10 - Stoppers make it possible to block the movement of the backrest in sofa position (A6) and bed (A7).
La hauteur de la partie Al (hl) détermine, avec la hauteur du piétement avant (h2) la garde au sol du 15 canapé et l'angle d'inclinaison de l'assise en mode canapé. Si h1 est égale à h2, l'assise demeure parallèle au sol.La partie Al relie l'axe de rotation AB5 à la partie A2. The height of the part Al (hl) determines, with the height of the front frame (h2) the ground clearance of the sofa 15 and the angle of inclination of the seat in couch mode. If h1 is equal to h2, the seat remains parallel to the ground. The Al part connects the axis of rotation AB5 to the part A2.
La partie A2 est parallèle au dossier (A4).Son 20 inclinaison par rapport au sol est fonction de l'angle du dossier recherché. Part A2 is parallel to the backrest (A4). Its inclination relative to the ground is a function of the angle of the desired backrest.
La hauteur de la partie A3 est égale à la hauteur du piétement B9 avant (h2). The height of the part A3 is equal to the height of the base B9 before (h2).
La partie A3 relie la partie A2 à la structure du 25 dossier. Part A3 connects Part A2 to the backrest structure.
A titre d'exemple (fig. 3) le dispositif permet un couchage de 120 cm de largeur. la longueur de couchage n'est pas limité par le dispositif. En 30 mode canapé, la profondeur d'assise avoisine 55 cm. By way of example (FIG 3) the device allows a coating 120 cm wide. the coating length is not limited by the device. In 30 sofa mode, the seat depth is around 55 cm.
