ABSTRACT:
A wheeled toy utilizes a pair of wheels mounted on an axle and moveable by an attached broom handle. A wire support straddles the two wheels, fitting over the outer ends of the axle, and a string assembly attached to the wire support facilitates a turning of the wheels relative to the handle. A fan spindle is rotatably attached to a plastic ball centered between the wheels, and a length of cord may be utilized to spin a plurality of radially mounted balls on the spindle. Alternatively, fan blades of various configurations can be used to rotate the spindle. The fan assembly includes colored rubber balls which orbit around the spindle, and one of the embodiments of the invention includes removable air scoops attachable to one or more balls so as to effectively operate as fan blades.
