Patent ID: 7878527

Claim:
A child carriage with a superstructure ( 6 ), particularly a seat, shell, or pouch, for a child, and with a collapsible frame ( 1 ; 31 ; 51 ), the carriage comprising a chassis ( 4 ; 34 ; 54 ) with a plurality of wheels ( 2 , 3 ; 32 ; 33 ; 52 ; 53 ; 53 ′), a frame ( 5 ; 35 ; 55 ) supporting the superstructure ( 6 ), and, disposed between said chassis and said frame, a folding mechanism ( 7 ; 37 ; 57 ) operative to vary the distance of said frame ( 5 ; 35 ; 55 ) for the superstructure ( 6 ) from said chassis ( 4 ; 34 ; 54 ), whereby said chassis ( 4 ; 34 ; 54 ) includes two longitudinal beams ( 8 ) which are rigidly interconnected in their front and back regions by in each case one transverse strut ( 9 ), whereby disposed at a back end of each longitudinal beam ( 8 ) is a journal bearing for the respective wheel ( 2 ), and wherein said folding mechanism ( 7 ; 37 ; 57 ) comprises at least two mutually parallel links ( 18 , 19 ; 40 , 41 ; 66 ; 67 ), characterized in that a) said links ( 18 , 19 ; 40 , 41 ; 66 ; 67 ) are articulated in the manner of a flat parallelogram linkage to said chassis ( 4 ; 34 ; 54 ), on the one hand, and to said support frame ( 5 ; 35 ; 55 ), on the other, such as to be pivotable about respective axes that pass generally perpendicularly through a plane of the parallelogram linkage, wherein b) said folding mechanism ( 7 ) is connected to both longitudinal beams ( 8 ) of the chassis ( 4 ), wherein the two links ( 18 , 19 ; 40 , 41 ; 66 , 67 ) on the same respective side of said child carriage frame ( 1 ; 31 ; 51 ) are articulated to a common mounting element ( 14 ; 36 ; 61 ) of said chassis ( 4 ; 34 ; 54 ), and further wherein c) the longitudinal beams ( 8 ; 58 ) are each divided into a front ( 59 ) and a back region ( 60 ) by the respective two lateral mounting elements ( 14 ; 36 ; 61 ) for each pair of said links ( 18 , 19 ; 40 , 41 ; 66 , 67 ), and wherein d) the connecting line between points of articulation ( 39 ; 65 ) of said links ( 18 , 19 ; 40 , 41 ; 66 ; 67 ), which lie approximately in a common plane to said chassis ( 4 ; 34 ; 54 ) forms a greater angle with the horizontal contact plane of the wheels ( 2 , 3 ; 32 ; 33 ; 52 ; 53 ; 53 ′) than with the verticals extending perpendicular to the plane, and wherein e) one of said two links ( 18 , 19 ; 40 , 41 ; 66 , 67 ) of a pair is extended ( 25 ) beyond its point of articulation ( 24 ) to said superstructure frame ( 5 ; 35 ; 55 ), whereby the extensions ( 25 ) of said two links are configured as a push bar ( 26 ).
