摘要

Improvements in the construction of archiving mechanisms, characterized in that it is constituted by a rigid spine, formed by two dihedral pieces, at right angles, of which two parts, one of each, are articulated by hinges, and the other two are carriers of the covers, held between said parts and some strips attached to them, which, at the same time, are carriers of curved rods, intended to pass through the archived documents, through holes provided for that purpose in advance in them, whose rods, when the mechanism is closed, they lodge their free ends in recesses arranged for that purpose in the other terminal strip.
