Abstract
Aspects of the present invention involve a steerable running stroller including a lower frame assembly supporting two rear wheels and an upper frame assembly supporting a front wheel. A self centering hinge mechanism, which may define a physical pivot axis or a virtual pivot axis, is coupled between the lower frame assembly and the upper frame assembly. The pivot axis defined by the self centering hinge mechanism is positioned at an angle, which may be an obtuse angle, such that the front wheel is normally in a straight orientation with respect to the rear wheels, and when a user imparts a turning force, the front wheel both turns and tilts relative to the rear wheels. When the turning force is removed, the self centering hinge mechanism acts to return the running stroller to a straight rolling orientation.
