Abstract
A collapsible stroller includes a stroller frame, at least one hinge mechanism, a wheel, and a swivel mechanism. The stroller frame is moveable between a deployed position and a collapsed position. The hinge mechanism allows for movement of the stroller frame between the collapsed position and the deployed position. The swivel mechanism connects the wheel to the stroller frame. The swivel mechanism includes a vertical axle, a cam follower, and a cam. The vertical axle connects with the wheel and is rotatable with respect to the stroller frame about a vertical axis. The cam follower is fixed to the vertical axle. The cam includes a sloped cam surface at least partially surrounding the vertical axle. The sloped cam surface contacts the cam follower to move the cam follower along the sloped cam surface, which results in rotation of the vertical axle about the vertical axis.
