Abstract

Improved children's rolling chair characterized because, being each of the axes, the front wheels and the rear ones, to pairs of rods parallel to each other and converging both pairs towards the upper part of the chair, the two collaterals are linked, in intermediate zones, to both sections of rod so that, in the resulting knots and, serving as an articulated link, extend two crossbars that, on the other hand, form the tensile supports of the flexible laminar body that constitutes the handle, serving also the front crosspiece as a support for the pivoting footrest; the pair of rods carrier of the front axle of wheels, has near its upper ends flanges in whose lower area the ends of the branches of another U-shaped rod are fixed articulately whose throat forms the upper handle of the chair also having a crossbar to which is fixed the flexible sheet that constitutes the backrest when extending between this crossbar and the back of the seat; the pair of rods, carrier of the rear axle of wheels articulates their respective upper ends to the branches of the u-handle; the frame thus formed, forms on each side a polygon of articulated vertices, triangle in position of use, and one of its sides constituted by two sections, support rod of the front axle and collateral branch of the handle which in the position of use are interlocked conventional that maintains its alignment and prevents the folding of the chair; all this in such a way that when freeing the aforementioned interlocking, the folding down of the handle back transforms said polygon into a deformable quadrilateral, impelling the rods of the anterior axis towards the rear leaving said axis above the posterior and fixing in stable position the total folding of the chair the fact that the articulated apex between branch of handle and rod of the rear axis becomes slightly concave.
