Abstract: In a invisible hidden door hinge (1), a first connecting body (2a) and a second connecting body (2b) are connected together by an articulation device (3) which allows the relative movement between a condition of opening and a closed condition in which the first (2a) and the second (2b) connecting body define a seat in which the articulation device (3) is enclosed. At least one of the connection bodies (2a, 2b) comprises a support structure (4a, 4b) in which, for a position adjustment, at least one movable body (5a, 5b) is housed which is shaped from a respective single metal sheet in a single concave piece having concavity defined by a bottom (52a, 52b) and by side walls (53a, 53b) that realize a continuous peripheral edge of the bottom (52a, 52b), joined to the bottom (52a, 52b) without interruption of the material of which said respective single metal sheet consists of and surrounding the bottom (52a, 52b) on at least three consecutive sides.

Abstract: In a invisible hidden door hinge (1), a first connecting body (2a) and a second connecting body (2b) are connected together by an articulation device (3) which allows the relative movement between a condition of opening and a closed condition in which the first (2a) and the second (2b) connecting body define a seat in which the articulation device (3). The articulation device (3) comprises at least one arm (32) with a first end (32a) on the first connecting body (2a) and a second end (32b), opposite to the second, on the second connecting body (2b). Said arm (32) is shaped from a respective single metal sheet in a single concave piece with concavity facing towards a reference plane parallel to the length direction (Z1, Z2) of the connection bodies (2a,2b) and passing through the ends (32a,32b) of the first arm (32).
