Improvements introduced in the folding structures of pantographic doors, characterized by arranging a series of vertical closure panels, each of which has a slot in its longitudinal edges, said slots being narrower in its mouth, and joints to compensate for the action of folding and unfolding of said panels, said joints joining each panel to its adjacent panels and comprising a strip of elastic, normal and essentially V-shaped material, said strip being finished along its longitudinal edges by ridges of a size that it allows them to slide away in the grooves of said vertical panels and said edges having openings at their opposite ends and means, inserted in said openings, to radially expand said edges until they come into frictional contact with the walls delimiting said grooves.
