The present invention concerns a concealed automatic door closing device (10) comprising an articulation hinge (20) comprising a pair of hinge bodies (21,22) respectively connectable to a leaf and to a fixed structure, wherein the hinge bodies (21,22) are articulated to each other through a pair of arms (23,24) to rotate around a hinge axis (A) between a closed hinge condition and an open hinge condition, and an automatic movement group (30) configured to control a movement of the articulation hinge (20) between the closed hinge condition and the open hinge condition and vice versa between the open hinge condition and the closed hinge condition and intermediate positions configured to act on a first arm (23) of the pair of arms (23,24) wherein the automatic movement group (30) comprises at least one rod (35) translatable along its own longitudinal development axis (B) and constrained to the first arm (23) at a first rod end in such a way that a translation of the at least one rod (35) causes a rotation of the first articulation arm (23) around the hinge axis (A) and, consequently, a movement of the articulation hinge (20) between the closed hinge condition and the open hinge condition, wherein the at least one rod (35) is housed in a corresponding rotatable sleeve (43) and is coupled to the corresponding rotatable sleeve (43) in such a way that a rotation of the rotatable sleeve (43) causes a translation of the rod (35) along the longitudinal axis (B), and a rotary actuator (49) configured to impart rotation to the rotatable sleeve (43), and is characterized in that the rotary actuator (49) comprises a rotating shaft (45) placed in rotation around a rotation axis (R) parallel to the longitudinal axis (B) along which the at least one rod is translatable.

The present invention relates to a concealed automatic door closing device (10) comprising an articulation hinge (20) comprising a pair of hinge bodies (21,22) respectively connectable to a leaf and to a fixed structure, wherein the hinge bodies (21,22) are articulated to each other through a pair of arms (23,24) to rotate around a hinge axis (A); and an automatic recall group (30) connected to a first arm (23) of the pair of arms (23,24) of the articulation hinge (20), wherein the automatic recall group (30) comprises a pair of elastic recall means (31), each mounted between a respective first abutment element (32) fixed in translation with respect to the first hinge body (21) and a respective second abutment element (33) translatable with a movement of the first arm (23) along a longitudinal axis (B); and it is characterized in that the automatic recall group (30) comprises a group (40) for adjusting the preload of the elastic recall means (31) configured to act in a centralised and synchronous manner on both the elastic recall means (31) of the recall group (30) in such a way as to modify the recall force exerted by each elastic recall means (31) by a substantially equal or proportional amount, and in that the adjustment group (40) comprises a central drive interface (41) configured to transfer a rotation imparted thereon (41) to a pair of rotating sleeves (43), wherein, when rotated, each rotating sleeve (43) of the pair of rotating sleeves (43) is configured to impart a movement along the longitudinal axis (B) of a respective second abutment element (33) moving it closer to or away from a corresponding first abutment element (32).
