Collapsible push chair

A collapsible push chair in which two transversely connected side frames each comprise:

• first and second legs (1 and 2) respectively provided with adjacent first ends (3 and 4) and with second ends (5 and 6);
• pivot means (7 to 10) providing articulation between the adjacent first ends (3 and 4) of the first and second legs (1 and 2);
• and
• a handle shaft (11);
• characterised in that:
• the handle shaft (11) is pivotally connected to said pivot means (7 to 10) for movement between a first position, in which the handle shaft (11) extends away from the first leg (1), and a third position, laterally adjacent the first leg (1), respectively on opposite sides of a second position in which the handle shaft (11) extends away from the second leg (2);
• locking means (12 to 15) are provided for releasably locking the handle shaft (11) in said first and second positions;
• drive means (16 and 17) interconnecting the handle shaft (11) and at least one of the first and second legs (1 and 2) for relative movement of the first and second legs (1 and 2) so that when the handle shaft (11) is in said third position the first leg (1) is laterally adjacent the second leg (2);
• and
• lost motion means (18 and 19) permitting movement of the handle shaft (11) from the first position to the second position without relative movement between the first and second legs (1 and 2).
