Abstract
Improvements in the manufacture of the mechanisms of articulation and subjection of stairs, which are characterized by the union of several elements articulated with each other, each of which is of reduced length and consists of two lateral, tubular, connected parts, by a crosspiece of the ladder that forms, therefore a tension between the aforementioned parts when the shaft is inserted in a hinge.
