摘要

The door (10) sliding system comprises upper and lower (12,14) sliding rails and a support roller (23) guided by the lower rail during door movement along a principal axis (Y). The roller is coupled to the lower part of the door by a ball joint (25). The internal profile of the lower guide rail is formed by two upper opposite concave regions (15',17') connected by a plane region (16).
