Abstract

Un réfrigérateur comprenant des éléments de rail linéaires (32) comportant des rails fixes (32a), des rails mobiles (32b), des rails intermédiaires (32c) et une pluralité de boules (32d) reliant ces rails les uns aux autres. Les rails fixes (32a) sont fixés à la paroi latérale d’une chambre de stockage (27) et l'encadrement (34) d’une porte de type tiroir est fixé aux rails mobiles (32b). On peut donc fournir une porte de type tiroir de haute qualité présentant moins de mouvement oscillant.
