STRUCTURALLY IMPROVED INVISIBLE CONCEALED HINGE FOR DOORS

摘要

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) shaped from a respective single metal sheet in a single concave piece having concavity facing a direction opposite to the depth direction (X1, X2) of the connecting body (2a, 2b) and defined by a bottom (42a, 42b) of the support structure (4a, 4b) and by side walls (43a, 43b) of the support structure (4a, 4b) that realize a continuous peripheral edge of the bottom (42a, 42b), joined to the bottom (42a, 42b) without interruption of the material of which said single metal sheet consists of and completely surrounding the bottom (42a, 42b) according to a closed curve around the depth direction (X1, X2) of the connecting body (2a, 2b).
