Collapsible two seat perambulator

Abstract

A buggy for transporting children has a frame ( 3 a, 3 b, 5 ) and wheels ( 9 ) that are rotatably mounted relative to the frame to support the frame above a ground surface. A primary seat ( 8 ) is operatively supported by the frame for supporting a first child. A secondary seat ( 17 ) is operatively supported by the frame for supporting a second child. The buggy is convertible between an in use configuration for transporting children and a folded storage configuration, whether or not the secondary seat is attached. The secondary seat may be detachable. The secondary seat may be positioned at least partly behind and at least partly below the primary seat.

1 . A buggy for transporting children, comprising:
 a 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 frame for supporting a first child;   a readily attachable and detachable secondary seat for supporting a second child;   wherein the buggy has an in use configuration for transporting children and a collapsed storage configuration, and is convertible between the in use configuration and the storage configuration whether or not the secondary seat is attached.   
     
     
         2 . A buggy as claimed in  claim 1 , wherein the secondary seat is readily attachable to the frame in a first position at least partly behind and at least partly below the primary seat. 
     
     
         3 . A buggy as claimed in  claim 2 , wherein the buggy is convertible between the in use configuration and the storage configuration whether or not the secondary seat is attached in the first position. 
     
     
         4 . A buggy as claimed in any one of  claims 1  to  3 , wherein the secondary seat is readily attachable to the frame in a second position at least partly above and at least partly in front of the primary seat.

         6 . A buggy as claimed in any one of  claims 2  to  5 , wherein the buggy is configured such that when the secondary seat is in the first position at least partly behind and at least partly below the primary seat, and the buggy is moved from the in use configuration to the collapsed storage configuration, at least part of the primary seat must move, at least to some extent, to enable the buggy to collapse. 
     
     
         7 . A buggy as claimed in  claim 6 , wherein the configuration is such that said at least part of the primary seat is manually moved to enable the buggy to collapse.

         9 . A buggy as claimed in  claim 8 , wherein the secondary seat has a secondary seat frame that pushes against the primary seat during the collapsing, causing the movement of at least part of the primary seat. 
     
     
         10 . A buggy as claimed in  claim 9 , wherein the secondary seat frame has a curved configuration to provide a smooth surface that engages the primary seat during the collapsing. 
     
     
         11 . A buggy as claimed in any one of  claims 7  to  10 , wherein at least part of the primary seat is invertible to provide clearance for the secondary seat. 
     
     
         12 . A buggy as claimed in any one of  claims 7  to  10 , wherein the primary seat is supported by an arrangement that enables the primary seat to move out of the way as the buggy is collapsed. 
     
     
         13 . A buggy as claimed in any one of  claims 1  to  12 , wherein the secondary seat is smaller than the primary seat. 
     
     
         14 . A buggy as claimed in any one of  claims 1  to  13 , wherein the secondary seat is pivotally supported by the frame. 
     
     
         15 . A buggy as claimed in  claim 14 , 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. 
     
     
         16 . A buggy as claimed in  claim 15 , 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. 
     
     
         17 . A buggy as claimed in any one of  claims 1  to  16 , wherein the primary seat is convertible from a sitting configuration for supporting a toddler to a lying configuration for supporting a baby. 
     
     
         18 . A buggy as claimed in any one of  claims 1  to  17 , wherein the primary seat is detachable from the frame. 
     
     
         19 . A buggy as claimed in  claim 18 , wherein the primary seat is readily attachable and detachable from the frame. 
     
     
         20 . A buggy for transporting children, comprising:
 a 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 frame for supporting a first child;   a 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.
