Title
(EN) COLLAPSIBLE PUSHCHAIR/CARRIER
(FR) POUSSETTE/CHARIOT PLIABLE
Abstract
(EN)
A collapsible pushchair/carrier (1) has wheels (12, 14) at the front and back. An upstanding spine (16) extends between the rear wheels (14) and handles (20). A lockable slider assembly (26) can be moved up and down the spine (16). The front wheels (12) are supported by wheel assemblies (22) connected by pivotable support legs (24) to the slider assembly (26). Beneath the slider assembly (26) there are pivot joints (40) linked to cranked support arms (38) pivotably connected to the support legs (24). A foldable transverse strut (46) extends between the front wheel assemblies (22). A seat (42) is mounted to the ends of the arms (38) remote from the pivot joints (40) to the legs (24) and the spine (16). The slider assembly (26) can be moved between two operating positions. In one position, the pushchair (10) is operative with the wheels (12, 14) defining a wheelbase (W) between the front and rear wheels and front and rear wheel tracks (F, R) between the front and rear wheels (12, 14) respectively. In the other position the pushchair (10) is stowed and collapsed with the legs (24) and arms (38) alongside the spine (16) and the front wheels (12) within the rear wheel track (R). The now folded strut (46) 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 (22) splay outwardly.
(FR)
L'invention concerne une poussette/chariot pliable (1) comportant des roues (12, 14) à l'avant et à l'arrière. Un montant principal (16) se dresse entre les roues arrière (14) et les poignées (20). Un assemblage coulissant verrouillable (26) peut être déplacé vers le haut et vers le bas du montant principal (16). Les roues avant (12) sont supportées par des assemblages de roues (22) reliés à l'assemblage coulissant (26) par des jambes support pivotantes (24). Sous l'assemblage coulissant (26) se trouvent des joints de pivot (40) liés à des bras support coudés (38) connectés pivotants aux jambes support (24). Un montant d'appui transverse pliable (46) s'étend entre les assemblages de roues avant (22). Un siège (42) est monté aux extrémités des bras (38), à l'écart des joints de pivot (40), aux jambes (24) et au montant principal (16). L'assemblage coulissant (26) peut être déplacé entre deux positions de fonctionnement. Dans la première position, la poussette (10) fonctionne avec les roues (12, 14) définissant respectivement un entraxe entre les roues avant et arrière et des empattements avant et arrière (F, R) entre les roues avant et arrière (12, 14). Dans la seconde position, la poussette (10) est rangée, les jambes (24) et les bras (38) pliés le long du montant principal (16) et les roues avant (12) se retrouvant à l'intérieur de l'empattement des roues arrière (R). Le montant d'appui (46) maintenant plié repose sur le sol afin de maintenir la poussette repliée dans une position verticale. En passant de la position rangée à la position de fonctionnement les assemblages des roues avant (22) prennent une orientation en biais vers l'extérieur.
