Improvements in the construction of folding doors of several leaves, of fractional movement to the sides, essentially characterized by the fact that the hinges of articulation of the leaves of the folding doors are located next to the upper and lower end thereof, in the form that the upper ones are equipped with a suspension system, consisting of a pair of wheels linked to a horizontal axis from which a stud moves downwards, which is housed in the union of the two parts of the hinge and which at the same time constitutes the axis of it.
