Abstract:
1. A collapsible box, comprising a rectangular base, on edges of which two major side walls that define flanks and two minor side walls that define front ends are hingedly coupled, and included in two opposite ones of said side walls, anchoring devices that include vertically movable central control pieces associated with horizontally actuated bolts, which in one position anchor the side walls through the extreme latches of the bolts and in another position release that anchor in order to fold down the four side walls on superimposed planes above the base, rotary bodies connecting the bolts to the central control pieces through two pairs of elastic portions, which in a resting position maintain the latches outwards engaging the front ends and the flanks, whereas when the central control pieces are moved upward against the resistance of the elastic portions, the latches are hidden releasing the front ends and the flanks, wherein the rotary bodies are hingedly coupled to short axes perpendicular to the plane formed by the front ends.
