A transporter for an infant comprising first and second means to receive an infant in the transporter, the means moveable between a first, closed orientation unsuitable for receiving an infant, and a second, open orientation for receiving an infant. The transporter further comprises first and second wheels disposed respectively at first and second ends of the transporter, the second wheel movable between a first operative position providing for a first wheel base and a second operative position providing for a second wheel base, wherein the first wheelbase is different from said second wheelbase, and wherein the second means is movable between the first and second orientations responsive to movement of the second wheel between the first and second operative positions.

1. A transporter for an infant comprising: first means to receive an infant in the transporter;second means to receive an infant in the transporter, said second means moveable between a first, closed orientation unsuitable for receiving an infant, and a second, open orientation for receiving the infant;a first wheel disposed at a first end of the transporter;a second wheel disposed at a second end of the transporter, said second wheel movable between a first operative position providing for a first wheel base and a second operative position providing for a second wheel base, wherein said first wheelbase is different from said second wheelbase,wherein, with said first means in a position capable of receiving an infant, said second means is pivotally movable between said first and second orientations responsive to movement of said second wheel between said first and second operative positions,wherein said second wheel couples to the transporter via a coupling mechanism, the coupling mechanism being in a closed orientation when said second wheel is in a first operative position and said second means is in a closed orientation, and the coupling mechanism being in an open orientation when the second wheel is in a second operative position and the second means is in an open orientation, andwherein the coupling mechanism comprises: a bridging bar with two ends, the first end being pivotally connected to a rear spine of said transporter,a radial leg with two ends, the first end being pivotally connected to said bridging bar remotely from said pivotal connection with said rear spine, the second end engaging with said second wheel,a connecting bar with two ends, the first end being pivotally connected to the second end of said radial leg, the second end being pivotally connected to said rear spine, said connecting bar including a hinge intermediate said two ends. 2. A transporter as claimed in claim 1, wherein the wheelbase of said first operative position is in the same plane as the wheelbase of said second operative position. 3. A transporter as claimed in claim 1 wherein said coupling mechanism further comprises a fixing bar with two ends, the first end being pivotally attached to said connecting bar, the second end being pivotally attached to said pivotal attachment of said bridging bar and radial leg. 4. A transporter as claimed in claim 1, wherein the second end of said bridging bar is shaped to form a seat for a child or infant. 5. A transporter as claimed in claim 1 wherein the second end of said bridging bar is shaped to form a receptacle. 6. A transporter as claimed in claim 1 wherein the second end of said bridging bar is shaped and positioned to form a platform on which a child or infant might stand. 7. A transporter as claimed in claim 1 wherein said coupling mechanism further comprises a fixing bar with two ends, said the first end being pivotally attached to said pivotal attachment of said rear spine and said connecting bar, the second end being pivotally attached to said radial leg. 8. A transporter as claimed in claim 1 wherein the coupling mechanism further includes a locking mechanism to lock said coupling mechanism in said closed orientation. 9. A pushchair including the coupling mechanism of claim 1. 10. A transporter as claimed in claim 1 or claim 2 wherein said second means comprises a child seat. 11. A transporter as claimed in claim 3 wherein said fixing bar is attached to said connecting bar at a position intermediate said rear spine and said hinge. 12. A transporter as claimed in claim 4 wherein said seat portion extends upwardly and outwardly away from said bridging bar. 13. A transporter as claimed in claim 4 wherein said seat includes a backrest pivotable between a closed position in which the backrest is substantially parallel to the base of the seat and an open position in which the seat is exposed. 14. A transporter as claimed in claim 12, wherein said radial bar includes a shelf portion such that when the second wheel is in the second orientation, and the coupling mechanism is in an open configuration, the shelf portion abuts the base of the seat, to provide a stop for the seat and to support a weight placed in the seat. 15. A transporter as claimed in claim 6 wherein said platform is positioned on said coupling mechanism in a position suitable for a standing child or infant. 16. A transporter as claimed in claim 7 wherein the second end of said bridging bar is shaped to form a seat for a child or infant. 17. A pushchair including the coupling mechanism of claim 7. 18. A transporter as claimed in claim 16 wherein said fixing bar extends outwardly from said pivotal attachment to said radial leg. 19. A transporter as claimed in claim 18 wherein said extended portion of said fixing bar provides a mounting for a back and sides of said seat. 20. A transporter as claimed in claim 19 wherein said bridging bar includes a shelf portion, said shelf portion abutting said radial leg to provide a stop for said seat when the second means are in the open configuration. 21. A transporter as claimed in claim 8 wherein said locking mechanism comprises a locking arm engageable with said rear spine and said radial leg.
