Abstract: An all terrain stroller has front, rear and intermediate frame members, a baby seat on the frame, and a pair of vertically movable wheels on the front frame member. Two rollers are mounted respectively on the front and rear frame members for travel over soft terrain, and the rear frame member also carries a pair of wheels at opposite ends of the roller with a diameter slightly larger than that of the roller. A foot operable mechanism raises and lowers the pair of movable wheels to engage a hard surface and raise the adjacent roller above the surface and selectively to lower the roller onto a soft surface.

Abstract: In an all-terrain baby carriage comprising a frame, a seat or cradle for the baby mounted on the frame, two drum-shaped wheels mounted fore and aft, and a swivelling steering wheel assembly mounted on a hinged frame member. The steering wheel assembly may be moved by the hinged frame member between a hard surface configuration wherein the steering wheel assembly is lowered into contact with the hard surface, with the front drum wheel being out of contact with the hard surface, and a soft surface configuration wherein both drum wheels are in contact with the soft surface with the steering wheel assembly being raised out of contact with the soft surface.
