Abstract

This utility model refers to a process for mechanical riveting whose evident object consists in allowing the definitive mechanical connection and fixing of parts and pieces, for instance hinges for hinged ladders, in a form that dismisses the means hitherto known and used in the art.
The fixing by this mechanical riveting process of, for instance, hinge (1) for hinged ladders consists in specially reamed recesses or drillings (3) made out in the inner parts (2) in a number depending from the applications and respective loads at stake, and in mechanical deformations or protrusions (5) made out by pressures exerted from outside upon the ends (4) of the outer parts of the connection to be established, in order to provoke the penetration of said deformations or protrusions (5) into said reamings (3).
