ABSTRACT:
An articulation for folding frames comprising a hollow internal support, which is adapted to support the ends of respective rods which are pivoted to the internal support in two spaced points, and a pair of bar-like elements, each being provided with a first end pivoted to a respective rod and a second end pivoted to a pivot; the pivot being slideable in a slot formed in the internal support and being fixed to an external support which is movable with respect to the internal support so as to define at least two positions: an open position, in which the rods form an angle with respect to each other, and a closed position, in which the rods are folded and substantially parallel.
