1. Apparatus comprising a vehicle pushchair frame assembly including a hinge device having a hinge axis, said hinge device having first and second hub devices moveable co-axially with respect to said hinge axis and a third hub device interposed between the first and second hub devices and moveable about said hinge axis, the first and second hub devices releasably engage with the third hub device for locking said vehicle frame assembly in an erected condition, wherein the first and second hub devices have inwardly-projecting lugs about their periphery and said third hub device includes at its periphery recesses, said recesses and said inwardly-projecting lugs arranged to loosely interdigitate in the erected condition, and wherein said inwardly-projecting lugs comprise inwardly-projecting ramped portions and said third hub device comprises, bounding said recesses, corresponding outwardly-projecting ramped surface portions, the arrangement being such that the first and second hub devices are moveable as aforesaid by movement of the third hub device about said hinge axis. 2. Apparatus according to claim 1, wherein said first and second hub devices are laterally disposed on respective opposite sides of said third hub device. 3. Apparatus according to claim 1, and further comprising a resilient device serving to urge said first and second hub devices towards said third hub device. 4. Apparatus according to claim 1, and further comprising a releasing mechanism connected to said third central hub device, said releasing mechanism being connected to a handle portion of said frame assembly. 5. Apparatus according to claim 4, wherein the first, second and third hub devices are housed in respective inner, outer and central housings of said hinge device, the central housing being connected to said handle portion. 6. A method comprising providing a vehicle pushchair frame assembly, locking the assembly in an erected condition, said locking including causing first and second hub devices of a hinge device of the frame assembly to engage releasably a third hub device interposed between the first and second hub devices, wherein the first and second hub devices have inwardly-projecting lugs about their periphery and said third hub device includes at its periphery recesses, said recesses and said inwardly-projecting lugs arranged to loosely interdigitate in the erected condition, and wherein said inwardly-projecting lugs comprise inwardly-projecting ramped portions and said third hub device comprises, bounding said recesses, corresponding outwardly-projecting ramped surface portions and unlocking the assembly by causing movement of said third hub device about a hinge axis thereby causing movement of the first and second hub devices co-axially with respect to said hinge axis, such movement of the hub devices releasing the first and second hub devices from a locking engagement with the third hub device. 7. A method according to claim 6, wherein said first and second hub devices are urged towards said third hub device by way of a resilient device. 8. A method according to claim 6, wherein said unlocking includes actuating a releasing mechanism attached to said third hub device to cause its movement about said hinge axis, and wherein said actuating includes operating a handle portion of said frame assembly connected to said releasing mechanism. 9. A method according to claim 6, wherein during said unlocking, the first and second hub devices move co-axially away from each other against the urging of said resilient device so that they no longer lockably engage with said third hub device. 10. A method according to claim 6, wherein said releasing enables said hinge device to be rotated about its axis of rotation and said frame assembly can be converted into a non-erected condition.
