Abstract

A support for trays, essentially characterized in that it is constituted by three frames, of which two are hinged in parallel at the respective ends of the third, the two first ones being identically constituted, each of which is formed by a rod which, by successive bends symmetrical, it establishes a bridge, whose horizontal section determines a lateral groove by means of the angled bending of the upper end of the frame as a flange and a transversal rod joined together under said flange, while the lateral branches of said bridge, folded upwards, determine a second bridge, with its horizontal section bent at an angle towards the same side of the anterior bridge, determining the end of this angle by means of a short crossbar fixed to the ends of said rod, the axis of articulation with the central frame or third frame ; establishing said second bridge of each side frame, with the first bridge, respective planes of an elastic bending angle, by the vertex that constitutes the unión of its branches, whose elasticity is given by torsion of the rod that constitutes each frame, in said vertices ; these elastic frames being collaterally transverse to the central frame, or third horizontal frame, the three frames forming an "H" profile, the pressurized tray being retained, with its edges in the grooves of said first bridges of each frame, while its bottom is supported on the angled ends of the second bridges and on the central frame; the latter being constituted by two parallel rods with twisted ends, joined together by short intermediate beams, whose ends determine the articulation of the collateral frames.
