Abstract

La présente invention concerne un ensemble pour déplacer au moins une porte mobile d'un meuble, laquelle porte est coplanaire avec une autre porte dans une position de fermeture. L'ensemble comprend deux chariots de support qui coulissent le long d'un profil de guidage qui définit une direction de coulissement pour chaque porte mobile. Chaque chariot comprend un mécanisme raccordable à une porte pour la déplacer entre la position de fermeture et la position de sortie, dans laquelle elle n'est plus coplanaire avec l'autre porte du meuble ; le mécanisme adopte une première configuration dans laquelle la première porte occupe la position de fermeture et une seconde configuration dans laquelle la première porte occupe la position de sortie. Selon l'invention, le mécanisme d'au moins l'un des chariots comprend un élément d'actionnement configuré pour interagir avec une butée fixable au meuble. Un tel élément d'actionnement entre en prise avec l'élément butée lorsque le mécanisme adopte la première configuration et empêche le coulissement du chariot le long du profil suivant un tel engagement. En outre, selon l'invention, l'élément d'actionnement se sépare de l'élément butée lorsque le mécanisme adopte une configuration prédéterminée, de préférence ladite seconde configuration, et permet le coulissement du chariot le long du profil suivant une telle séparation.
