ABSTRACT:
A collapsible pushchair/carrier has wheels at the front and back. An upstanding spine extends between the rear wheels and handles. A lockable slider assembly can be moved up and down the spine. The front wheels are supported by wheel assemblies connected by pivotable support legs to the slider assembly. Beneath the slider assembly there are pivot joints linked to cranked support arms pivotably connected to the support legs. A foldable transverse strut extends between the front wheel assemblies. A seat is mounted to the ends of the arms remote from the pivot joints to the legs and the spine. The slider assembly can be moved between two operating positions. In one position, the pushchair is operative with the wheels defining a wheelbase between the front and rear wheels and front and rear wheel tracks between the front and rear wheels respectively. In the other position the pushchair is stowed and collapsed with the legs and arms alongside the spine and the front wheels within the rear wheel track. The now folded strut rests on a floor surface to support the stowed pushchair in an upstanding position. In moving between the stowed and operative positions the front wheel assemblies splay outwardly.
