Abstract

Folding armchair, which is essentially characterized by consisting of two tubular frames articulated with each other, an open "U" that serves as a backup, and a closed rectangular that serves as a seat by a continuous canvas conveniently attached to both, producing the mutual articulation of said pieces between two points located near the rear crossbar of the seat and two others established a quarter of a height from the lower ends of said piece in "U", with the particularity that, approximately within the middle of this articulate, on the other hand, the armrests of the armchair consisting of handrails of "L" profile frontally finished by the horizontal wing itself curved downward, producing near these frontal ends the articulation of a tubular upright also in "U" that, in its first third, also articulates with the frame of the seat and extends appreciably downwards, constituting the crosspiece of the "U" the support front of the chair on the floor; articulating in the common points of conjunction between the front upright and the seat frame there are, in addition, the ends of another tubular rear upright, also in "U", which is directed backwards to form the rear support of the chair on the floor, being verified by the low part of such upright, near the corresponding crossbar, the link thereof with the lower terminals of the backrest by means of articulation of small double arm braces each, which are provided with length such that, within the position useful armchair, are directed upwards providing due stability to the structure by forcing the thrust of the terminals of the backrest on the rear pillar of the chair, while said braces enable the folding of this on itself by downward rotation, determining the convenient displacement of the lower ends of the backrest towards the crossbar of the rear post .
