Abstract
A children's wagon has a molded plastic body including a horizontal floor with surrounding pockets. The wagon also includes front and rear wheels with the former mounted upon a pivoting bolster to which a handle is attached. Molded plastic front, rear and side walls surround the horizontal floor and are removably fastened to the body via their bottom edges by tabs and hook projections that engage the wagon body pockets. Horizontal surfaces are formed adjacent to the side edges of the front, rear and side walls. A knob and a cup are formed on each horizontal surface. The knobs of the side walls engage the cups of the front and rear walls while the knobs of the front and rear walls engage the cups of the side walls so that the front, rear and side walls are joined together in a secure but removable fashion.
