1. A wearable protection device comprising:
a modular frame with an upper shaped member and a lower shaped member pivotally connected to a medial shaped member interposed therebetween; and
hinge means for hinging said shaped members therebetween at corresponding hinging points and around respective rotation axes, each of said hinge means comprising a pivot element and a disc element;
wherein the pivot element and the disc element are permanently coupled by riveting of the pivot element by a hammering tool, whereby an end of the pivot element is closely aligned or flush with the disc element after riveting;
wherein said pivot element comprises a hollow unthreaded distal portion and said disc element comprises a second internally threaded axial projection forming a central through hole, said unthreaded distal portion being designed for being inserted through said central through hole and said unthreaded distal portion being designed for being deformed by riveting after passing through said central through hole;
wherein said pivot element comprises a base portion designed to be secured to one of said at least two shaped members;
wherein brackets of the upper and the lower shaped members have, at each hinging point, a respective elongated eyelet with a predetermined width, the hinge means being secured to the medial shaped member and inserted into the elongated eyelets of the upper or the lower shaped members previously superimposed; and
wherein a first axial projection of the pivot element comprises a first threaded portion having a minimum outer diameter and the unthreaded distal portion having an outer most diameter being lesser than the minimum outer diameter of the first threaded portion, both of the diameters being smaller than the width of the eyelets, while the base portion of the pivot element has a transverse size bigger than the width of the eyelets, the first axial projection of the pivot element being adapted to be inserted inside the elongated eyelet of the shaped members, the first threaded portion being adapted to be in threaded engagement with the second internally threaded axial projection of said disc element.
