<p>A pushchair is provided with a folding frame comprising front wheels (18) provided at the end portion of a first stationary bar (10) aligned along the centre-line plane, as well as a second movable bar (20), and rear wheels (48) provided at the bottom end portion of two respective bars (40). All four bars extend to converge into a mechanism comprising two pairs of bevel gears (62, 68), which enables both the movable bar (20) and the rear bars (40) to align into a parallel arrangement relative to the stationary bar (10) through solely angular movements. A locking device (200) is provided to prevent the pushchair from being able to fold into any other configuration than the ones corresponding to the configurations taken by the pushchair when the frame is fully open and fully closed.</p> |
