Support and operating device of sliding doors, in particular for wardrobes

Support and operating device for sliding doors, in particular for wardrobe cabinets, suitable for determining the support and operating and sliding of the doors (6) in alternate longitudinal directions in positions coplanar to each other, wherein the doors (6) are actuated so as to shift from a closed position in which they are adjacent and aligned with each other and in relation to the front of the cabinet (5), to an open position wherein they are first shifted forwards by a limited stroke and then made to slide laterally into the desired position, parallel to the front face of the cabinet, and vice versa, wherein the cabinet (5) is delimited by a flat rear back (7), by two flat lateral sides (8, 9), by a flat upper top delimiting a free upper space with an underlying horizontal shelf (16), attached between the sides (8,9) and by a flat lower bottom (10) delimiting a free lower space with an underlying horizontal shelf (17), and wherein the doors 6 are fitted with handles (11,12) to move them from the closed position to the open position and vice versa, characterised by at least one upper group of component parts and one lower group of component parts for each door (6), respectively installed and attached in said upper free space and said lower free space, said upper group being substantially composed of support means (18) attached above said horizontal shelf (16) and supporting mobile means (22) suitable for supporting the upper part of each door (6), and sliding from a rear end-stop position in which the door (6) is moved into the lowered closed position, to a front end-stop position in which the door (6) is moved into the raised open position and shifted onto the front face of the cabinet (5), and vice versa, and wherein such sliding takes place by means of the guided sliding of said mobile means (22) along inclined planes (45), with downward inclination from the front to the rear of the cabinet (5), said mobile means (22) being stressed by first elastic means (61) supported by said support means (18) exerting a form of balancing on the door (6) during the movement thereof, which helps to maintain a correct parallel and orthogonal position of the door (6) in all the shifted positions thereof;

• characterised in that the upper part of said door (6) is shaped so as to be attached to said mobile means (22) and to contain first guide means (55) cooperating with second guide means (46) attached to said support means (18), to permit the alternate lateral sliding of the door, only when the same is moved into its open position;
• characterised in that said lower group is substantially composed of further support means (69) attached under said horizontal shelf (17), and by further mobile means (71) supported by said further support means (69) and cooperating with guide and slide means (70,75.78,79) attached to the lower part of said door (6), said further mobile means (71) being suitable for being shifted from a rear end-stop position, in which the door 6) is moved to the lowered closed position, to a front end-stop position in which the door (6) is moved into the raised open position, moved to the front of the cabinet (5) and vice versa, and wherein such sliding takes place by means of the guided sliding of said further mobile means (71) along inclined planes (103) with the same inclination, size and arrangement of the inclined planes (45) of said upper group, said further mobile means (71) being stressed by second elastic means (112) supported by the same and exercising on the door (6) a form of balancing during the movement thereof, which helps to maintain a correct orthogonal and parallel position of the door (6) in all the shifted positions thereof, in the condition in which the sliding position of said further mobile means (71) is constantly aligned and correspondent to the sliding position of said mobile means (22);
• and lastly characterised in that said lower guide and sliding means (70, 75, 78,79,) of the door (6) are further co-operating with said further support means (69) to permit the alternate lateral sliding of the door, only when it is shifted to the open position.
