<p>A device for locking and unlocking the folded and unfolded positions of an infant pushchair, during the folding and unfolding operations the handlebar (R) being slid on the front legs (P), the device being actuated by means of a rope (9) and comprising a lock (1) at each side. This device is characterised in that the lock (1) comprises a housing (2) having an open lower portion (3) and housing the active element (4), a flat (5,6) being slidably fitted to each of the lateral faces of the housing (2), said flats (5,6) being connected together at an end at which they are actuated by means of the rope (9), each of said flats in its central region having an oblique slot (10), a pin (11) extending through the active element (4) being in a position to be shifted along said oblique slots, said active element (4) being transversally shifted in the empty space of the housing (2) when the flats (5,6) are made to carry out a longitudinally shifting motion and thus bringing about the locking and unlocking with respect to the locking points (13,14) being provided on the front legs (P).</p> |
