ABSTRACT:
A wheel assembly for a baby stroller in which the wheel or wheels are mounted to the trailing portion of a linkage assembly that is pivotally carried at its midportion by a lower support. The leading portion of the linkage assembly is located ahead of the wheels and is connected by a tension spring to an upper support. Upward travel of the wheels is resisted by extension of the spring. The lower support mounts a lock movable into lock and release positions. In the lock position the lower support is prevented from rotating about a vertical axis relative to the upper support. In the release position such rotation can occur. Consequently, the baby stroller can be turned around and pushed in a direction opposite the original direction of travel once the wheel assemblies are properly oriented.
