Abstract

Un tiroir pliable (100) composé d'une plaque en plastique composite comporte deux panneaux latéraux (2), un panneau de base (1), un panneau arrière (3) et un panneau de couverture (4). Les panneaux latéraux (2), panneau de base (1), panneau arrière (3) et panneau de couverture (4) comportent chacun une plaque frontale en plastique (11) et une partie moulée par injection (12). La plaque frontale en plastique (11) moulée par extrusion ou moulée par aspiration de plastique après extrusion, et la partie moulée par injection (12) sont assemblées par soudage ou collage. Dans la position de connexion des deux panneaux latéraux (2) avec le panneau de base (1), des articulations pliables sont prévues pour réaliser une connexion articulée par extrusion de la plaque frontale (11) ou de la partie moulée par injection (12). Dans la position de connexion de l'extrémité arrière du panneau de base (1) avec le panneau arrière (3), une articulation pliable est prévue pour réaliser une connexion articulée par extrusion de la plaque frontale (11) ou de la partie moulée par injection (12). L'extrémité arrière des panneaux latéraux (2) est connectée par encastrement avec le panneau arrière (3). L'extrémité frontale des panneaux latéraux est connectée par encastrement avec le panneau de couverture (4).
