Collapsible two seat perambulator

1. A buggy for transporting children, comprising:

a frame comprising a primary seat frame for supporting a primary seat, the primary seat frame comprising a first section and second section connected via one or more couplings;

a plurality of wheels that are rotatably mounted relative to the frame to support the frame above a ground surface and which enable the buggy to be moved along the ground surface;

a forward-facing primary seat operatively supported by the frame for supporting a first child;

a forward-facing secondary seat operatively supported by the frame for supporting a second child and that is positioned at least partly behind and at least partly below the primary seat;

wherein the buggy is convertible between an in use configuration for transporting children and a folded storage configuration without removing the secondary seat, and the secondary seat is positioned at least partially within the primary seat frame in the folded storage configuration; and

wherein the primary seat is convertible from a sitting configuration for supporting a toddler to a lying configuration for supporting a baby.

2. A buggy as claimed in claim 1 , wherein the secondary seat is readily attachable and detachable at a forward-facing position at least partly behind and at least partly below the primary seat.

3. A buggy as claimed in claim 1 , wherein the secondary seat is attachable to the frame in a second position at least partly above and at least partly in front of the primary seat.

4. A buggy as claimed in claim 3 , wherein the buggy is convertible between the in use configuration and the folded storage configuration whether or not the secondary seat is attached in the second position.

5. A buggy as claimed in claim 1 , wherein the buggy is configured such that when the secondary seat is positioned at least partly behind and at least partly below the primary seat, and the buggy is moved from the in use configuration to the folded storage configuration, at least part of the primary seat must move, at least to some extent, to enable the buggy to fold.

6. A buggy as claimed in claim 5 , wherein the secondary seat has a secondary seat frame that pushes the primary seat during the collapsing, causing the movement of at least part of the primary seat.

7. A buggy as claimed in claim 1 , wherein at least part of the primary seat is invertible to provide clearance for the secondary seat.

8. A buggy as claimed in claim 1 , wherein the secondary seat is smaller than the primary seat.

9. A buggy as claimed in claim 1 , wherein the buggy is configured such that the secondary seat is selectively pivotable from an in use position to a storage position, without collapsing the remainder of the buggy.

10. A buggy as claimed in claim 9 , wherein, following the movement of the secondary seat to the storage position, the remainder of the buggy can then be collapsed around the secondary seat.

11. A buggy as claimed in claim 1 , wherein the secondary seat is positioned at least partially between the first and second sections of the primary seat frame in the folded storage configuration.

12. A buggy as claimed in claim 1 , wherein the secondary seat comprises one or more quick release connectors for readily attaching and detaching the secondary seat to the frame at a forward-facing position at least partly behind and at least partly below the primary seat.

13. A buggy for transporting children, comprising:

a frame comprising a primary frame and a secondary frame;

a plurality of wheels that are rotatably mounted relative to the frame to support the frame above a ground surface and which enable the buggy to be moved along the ground surface;

a primary seat operatively supported by the primary frame for supporting a first child;

a readily attachable and detachable secondary seat operatively supported by the secondary frame for supporting a second child, the secondary seat being readily attachable and detachable at a forward-facing position at least partly behind and at least partly below the primary seat;

wherein the primary frame comprises a first section and a second section connected via one or more couplings, and one or more of the couplings comprises one or more quick release levers configured to switch between a first position allowing the first section to rotate relative to the second section, and a second position holding the first and second sections at an articulated position.

14. A buggy as claimed in claim 13 , wherein the buggy is convertible between an in use configuration and a storage configuration whether or not the secondary seat is attached to the secondary frame.

15. A buggy as claimed in claim 13 , wherein the secondary seat comprises one or more quick release connectors for readily attaching and detaching the secondary seat to the frame at the forward-facing position.

16. A stroller for transporting children, comprising:

a frame comprising a primary seat frame for supporting a primary seat;

a plurality of wheels that are rotatably mounted to a wheel support frame to enable movement of the stoller about a ground surface;

a forward-facing primary seat connected to the frame and configured to support a first child;

a readily attachable and detachable forward-facing secondary seat connectable to the frame and configured to support a second child, the secondary seat comprising one or more quick release connectors for readily attaching and detaching the secondary seat to the frame at a forward-facing position at least partly behind and at least partly below the primary seat;

wherein the buggy is convertible between an in use configuration for transporting children and a folded storage configuration without removing the secondary seat, and the secondary seat is positioned at least partially within the primary seat frame in the folded storage configuration.

17. A stroller as claimed in claim 16 , wherein the primary seat frame comprises a first section and a second section connected via one or more couplings, and the secondary seat is positioned at least partially between the first and second sections of the primary seat frame in the folded storage configuration.

18. A stroller as claimed in claim 16 , wherein the secondary seat is selectively movable from an in use position to a storage position without collapsing the primary seat frame of the stroller, and, following the movement of the secondary seat, the primary seat frame is selectively collapsible around the secondary seat.

19. A buggy as claimed in claim 16 , wherein the secondary seat is pivotally supported by the frame.
