<p>The door (10) comprises a leaf (12) and a horizontal sliding system (18) arranged to guide the leaf (12) in the opening/closing movement along a longitudinal direction (F). The sliding system (18) comprises a rail (24, 26) and a pair of ramps (44, 46). The leaf (12) is provided with two rollers (20) by means of which it is hanged to the sliding system (18). The rollers (20) are in contact with respective rolling surfaces (32, 34) of the rail (24, 26) to roll along these surfaces during the opening/closing movement of the door. The sliding system (18) further comprises a pair of ramps (44, 46), each of which forms a rolling track (48, 50) arranged to cooperate with a respective roller (20) to cause the roller (20), and hence the leaf (12), to move both downwards and towards the inside of the door in a direction perpendicular to the plane of the leaf (12). The rail (24, 26) comprises a first rail portion (24) and a second rail portion (26), each of which forms an upper rolling surface (32) and a lower rolling surface (34). The two rail portions (24, 26) have an identical cross-section of symmetrical shape with respect to a horizontal plane of symmetry. The two ramps (44, 46) are made as separate components with respect to the two rail portions (24, 26) and are identical to each other. The two ramps (44, 46) have a symmetrical configuration with respect to the aforesaid plane of symmetry and are mounted one (44) between the two rail portions (24, 26) and the other (46) at the end of either (26) of the two rail portions (24, 26).</p> |
