lacking of one of its smaller sides (2), each of which frames

smaller module, for which reason, in the folded position,
every module (1) of the ladder is inscribed inside the frame of
the foregoing one, except the largest (1A) corresponding to
one end of the ladder, and by swinging them, the modules
(1) become alternatively placed in such a position with
respect the ones the others that the ends of the arms of the
other group of modules, all them becoming placed in the
same plane, out of which they are taken at the user's will by
