Abstract

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).
