Abstract

L'invention concerne un système télescopique, en particulier pour des appareils ménagers, qui comprend deux dispositifs de guidage télescopique (5) espacés l'un de l'autre qui sont fixés respectivement avec un rail de guidage stationnaire (6) sur un corps ou une grille latérale (3) et présentent respectivement un rail de roulement (8) monté de manière déplaçable sur le rail de guidage (6) ou sur un rail médian (7), le déplacement des deux rails de roulement (8) étant synchronisé par l'intermédiaire d'une traverse (10, 10', 20, 20', 20", 30, 30', 30") qui est disposée indirectement ou directement sur des côtés opposés sur un rail de roulement (8). Cela permet d'éviter une rentrée ou une sortie d'un seul rail de roulement (8), ce qui simplifie la manipulation lors du placement d'objets sur les rails de roulement (8).
