ABSTRACT:
A foldable baby carriage comprises a pair of front legs (10), a pair of rear legs (14) pivotally connected at their upper ends (15) to the front legs (10), a pair of support angle bars (20) pivotally connected at their one end (21) to the middle regions of the rear legs (14), a pair of pusher rods (2) pivotally connected at their lower ends to the other ends (22) of the support angle bars (20), slidable and pivotal connecting members (5) slidably and pivotally connecting the upper ends of the front legs (10) to the pusher rods (2), a pair of transverse connecting rods (24) operatively connecting the front legs (10) and support angle bars (20) together, a front leg connecting rod (11) extending between the front legs (10), a rear leg connecting rod (18) extending between the rear legs (14), and a pusher rod connecting rod (4) extending between the pusher rods (2). In the folding operation, while the slidable and pivotal connecting members (5) are sliding on the pusher rods (2), the pivotally connected portions turn. The turning movement of the support angle bars (20) on the rear legs (14) acts to sufficiently increase the height of the pusher rods (2) of the baby carriage in the opened state and sufficiently decrease the overall height of the baby carriage in the closed state.
