The door leaves include a guiding device, the action of which is damped during the opening and closing movement by magnetic devices and damping systems that counteract their attraction force. ## Claims ### Claim 1 A device configured to move a hinged door leaf and open the hinged door leaf completely, the hinged door leaf opening comprising a first door leaf (A) hinged to a fixed structure and adapted to rotate from a first configuration, in which a compartment defined inside a wardrobe is closed to a second configuration, in which the wardrobe is open, the device comprising: a first rod (D1) hinged between an external side of a top (C) of the wardrobe and an upper edge of said first door leaf (A), in such a way that the first rod rotates on a plane which is parallel to the top (C), the first rod comprising at least a first half rod and a second half rod (D11, D12) that are engaged to each other and slide longitudinally one on top of the other so as to increase/decrease a distance between a first hinge point on the top of the wardrobe and a second hinge point on the door leaf (A), wherein said second half rod (D12) is equipped with shock absorbing devices or braking and damping devices (P1) operated through magnetic attraction and integral with the second half rod (D12), the shock absorbing devices or braking and damping devices counteracting an opening movement and braking a closing movement of the first door leaf (A), wherein said shock absorbing devices or braking and damping devices (P1) are configured as magnetized pins and said first half rod includes magnetized hollow cylinders, and wherein a sliding of the second half rod on top of the first half rod causes said pins to be received in said hollow cylinders and to have the magnetic attraction therewith. ### Claim 2 (depends on 1) The device according to claim 1, further comprising: a second door leaf (B) hinged to said first door leaf (A), wherein said first and said second door leaves (A, B) rotate from the first configuration in which the compartment is closed to the second configuration in which the compartment is open, said first and said second door leaves (A, B) comprising rotation guiding devices; wherein said shock absorbing devices or braking and damping devices (P1) counteract the opening movement and brake the closing movement of the first door leaf (A) and also of the second door leaf (B) hinged to said first door leaf (A); and a second rod (D2) hinged between said external side of the top (C) of the wardrobe (M) and an upper edge of said second door leaf (B), in such a way that the second rod rotates on a plane which is parallel and in proximity of the top (C). ### Claim 3 (depends on 2) The device according to claim 2, wherein said first and said second rods (D1, D2) are positioned on the top of the wardrobe or walk-in closet or piece of furniture, and wherein one or both of said rods (D1, D2) are hinged on a bushing or a locking or coupling device. ### Claim 4 (depends on 1) The device according to claim 1, wherein said first rod (D1) comprises guides (G2) for a mutual sliding movement between said first half rod (D11) and said second half rod (D12). ### Claim 5 (depends on 1) The device according to claim 1, wherein said shock absorbing devices or braking and damping devices (P1) operated through magnetic attraction dampen the opening and closing movement of the door leaf (A) during opening and closing and at the same time bring said first door leaf (A) back and hold it in said open and closed configurations. ### Claim 6 (depends on 1) The device according to claim 1, wherein said first rod (D1) is directly or indirectly hinged to said first door leaf (A) through a rod adjusting or supporting element (S1) and a plate (S3), by which it is possible to adjust a rotation of said first rod (D1) with respect to the first door leaf (A). ### Claim 7 (depends on 1) The device according to claim 1, wherein said first door leaf (A) is hinged to a jamb or vertical door leaf (F), or to a fixed component of the wardrobe with concealed hinges configured to allow a complete 180° rotation. ### Claim 8 (depends on 1) The device according to claim 1, further comprising damping elements (CP1) positioned inside cavities of the hollow cylinders (CC1), said damping elements being disposed to become compressed by action of the pins.
