Abstract

L'invention concerne un dispositif (43) pour déplacer des éléments d'un meuble (1,2) mobiles l'un vers l'autre au moyen d'une unité d'entraînement qui permet de déplacer un premier élément de meuble (2) relativement à un deuxième élément de meuble (1). Un bras formé entre les éléments du meuble (1,2) et pivotant au moyen de l'unité d'entraînement est conçu de façon que le pivotement du bras entraîne le mouvement du premier élément de meuble (1). L'invention est caractérisée, entre autres, en ce que des moyens d'appui destinés à lier au moins temporairement une section terminale du bras à un des éléments de meuble (2) interviennent dans le mouvement de rotation du bras. L'invention porte également sur un meuble comportant un premier élément de meuble (2) mobile relativement à un deuxième élément de meuble (1), ce meuble étant équipé d'un dispositif de ce type.
