摘要

Improvements in the closing mechanisms governed by springs, according to which these are constituted by a mobile laminar piece that on its upper side has produced an incoming cut that forms the bolt, and on its surface there are four notches regularly spaced to pass through as many tabs for fixing a plate whose upper side forms a flap that partially covers the locking part of the closure, in collaboration with a protrusion of the material itself of the insert on which the said blocking piece rests, and a stop stem which determines the two limiting positions of it.
