Sofa bed with innovative innovative position adjustment mechanism and a fast assembly process, comprising padding elements, a base structure (1) a plurality of mutually hinged frames (2) supported by said base structure and supporting said padding elements, and a kinematic mechanism (3) to change the frames positions; moreover, the base structure comprises two identical elements, named "small legs" (4), a spacer (5), and is characterised by a "hinge" plate (6) consisting of two flat surfaces, fixed on the small leg (4), which consists of two flat surfaces with an almost rectangular hole (7); said hole is tapered on one side (8) to lodge the spacer (5). This assembly procedure removes the clearance in the coupling between the hinge (6) and the spacer (5) and obtains a perfect perpendicularity between the spacer and the "small leg" (4). According to a subsequent aim the base structure assembly is realised by only two bolts.

L'invention concerne un canapé-lit à assemblage rapide équipé d'un mécanisme de réglage de position innovant, lequel canapé-lit comporte des éléments de rembourrage, une structure de base (1), une pluralité de cadres (2) articulés entre eux, supportés par ladite structure de base et supportant les éléments de rembourrage, ainsi qu'un mécanisme cinématique (3) servant à changer les positions des cadres. La structure de base comporte également deux éléments identiques, appelés "petits pieds" (4), ainsi qu'une barre d'écartement (5) et est caractérisée par une plaque d'articulation (6) constituée de deux surfaces plates fixées sur le petit pied (4), lesdites surfaces plates présentant un orifice (7) presque rectangulaire, biseauté sur un côté (8) de façon à pouvoir loger la barre d'écartement (5). Cette procédure d'assemblage élimine le jeu dans l'accouplement entre l'articulation (6) et la barre d'écartement (5) et permet d'obtenir une perpendicularité parfaite entre ladite barre d'écartement et le "petit pied" (4). Selon un objectif ultérieur, l'assemblage de la structure de base est exécuté avec seulement deux boulons.
