Abstract
Automatic closing mechanism for doors, which is constituted by a fixed part to the frame, on which articulates a second mobile centerpiece, linked to the first one also by an adjustable tension spring, in such a way that it can be rotated on the fixed part to the frame, initially overcoming the tension of said spring, further characterized by that by varying the position of the moving part the spring tension itself favors the rotation in the opposite direction of this piece.
