Abstract

A toy stroller includes two cross-hinged bottom tubes ( 10 ), two cross-hinged rear tubes ( 12 ), two front legs ( 16 ), and two handle tubes ( 14 ). An end ( 100 ) of each bottom tube ( 10 ) is detachably coupled to one of two connecting members ( 30 ) fixed to an end ( 122 ) of one of the rear tubes ( 12 ). The other end ( 102 ) of each bottom tube ( 10 ) is detachably coupled to one of two coupling members ( 32 ) fixed to one of the front legs ( 16 ). An upper section ( 160 ) of each front leg ( 16 ) is detachably coupled to one of two sleeves ( 18 ) fixed to a lower end ( 142 ) of one of the handle tubes ( 14 ). The other end ( 120 ) of each rear tube ( 10 ) is detachably coupled to one of two engaging members ( 34 ) fixed to an upper end ( 140 ) of one of the handle tubes ( 14 ).
