A foldable baby carriage or infant carrier comprises a pair of slide guide rods, a pair of sliders slidable on the slide guide rods, a pair of front legs turnably connected at the upper end thereof to the sliders, a pair of rear legs turnably connected to the intermediate portions of the front legs, a pair of support angle bars turnably connected at one of their respective ends to the intermediate portions of the rear legs and at the other ends thereof to the lower ends of the slide guide rods, and a pair of foldable operative connecting rods which are turnably connected in such a manner as to connect the above-mentioned intermediate portions to the slide guide rods at positions spaced a predetermined distance from the lower ends thereof. During the folding operation, the various connecting portions turn while the sliders slide on the slide guide rods. In the folded state, the support angle bars overlap the slide guide rods, so that the overall height has been decreased.

A collapsible infant carrier comprising: a pusher member (101, 1) having a pair of substantially vertically extending slide guide rods (104, 3), a pair of sliders (105, 4) which are slidable on said slide guide rods (104, 3), a pair of front legs (107, 6) turnably connected at their upper ends to said sliders (105, 4) to form a pivotal coupling, said pair of front legs having a pair of front wheels connected to the respective lower ends of said pair of front legs, a pair of rear legs (112, 9) turnably connected to said front legs (107, 6) in the intermediate portions thereof to form a pivotal coupling, said pair of rear legs having a pair of rear wheels connected to the respective lower ends of the pair of rear legs, a pair of support angle bars (117, 15) turnably connected at one of their respective ends to said rear legs (112, 9) in the intermediate portions thereof to form a pivotal coupling and at the other ends thereof to the lower end of said pusher member (101, 1) to form a further pivotal coupling; a pair of folding operative connecting rods (120, 18) which are turnably connected to the intermediate portions of said front legs (107, 6) to form a third pivotal coupling and turnably connected to the pusher member (101, 1) at positions spaced a predetermined distance from the lower end of the pusher member to form a fourth pivotal coupling, and width defining connecting rod means for defining the widthwise measured dimension between one side of the carrier defined by one of said slide guide rods, one of said front legs, and one of said rear legs, and the other side of the carrier defined by the other slide guide rod, the other front leg and the other rear leg, whereby the carrier is collapsible in the front to back direction between an opened state and a closed state by the sliding action of the sliders (105, 4) on the pusher member slide guide rods (104, 3) and by the turning action of the respective pivotal couplings including the turning of the support angle bars (117, 15) relative to both the rear legs (112, 9) and the pusher member (101, 1) simultaneously, so that the front wheels and rear wheels are brought together in the front to back direction to form a stable pedestal wheel base and so that the pusher member (101, 1), slide guide rods (104, 3), pair of front legs (107, 6), pair of rear legs (112, 9), and folding operative connecting rods (120, 18) are collapsed to generally vertical orientation in adjacent relationship to form a collapsed generally vertical assembly centered and supported over the stable pedestal wheel base when the carrier is collapsed to the closed state.
