ABSTRACT:
The invention refers to some improvements in the foldable frames for children's pushchairs, of the type which includes the handlebar fitted slidingly over the front legs, with the folding of the pushchair being obtained with the bringing down of the handlebar. With these improvements, a very complete, light children's pushchair with a simple structure and very compact folding up is obtained. These advantages are achieved by structuring the frame on the basis of a linked triangulation formed on each side by the rear (3) and front (1) legs, and by a base frame (5), the rear leg (3) being linked by its upper end (9) on a solidly jointed flange (7) of the lower end of the brace members of the handlebar (6) and along which it slides guided by the front leg (1), the front (1) and rear (3) legs being related to each other by the base frame (5) and the front legs (1) being finished off at the top with a guiding flange (8) along which the corresponding brace member of the handlebar (6) slides.
