摘要： A collapsible top (13) fits over a child's pull wagon (10), may be taken apart easily, and flatly packaged for store display or mail order shipment. It has a light weight, flexible frame (15) universally adjustable to fit the various sizes of wagon beds (12). In principle, however, the top may be scaled up as a tent for adults, or as a canopy for outdoor recreation. The top includes a cover material (14) stretched between a pair of spaced hoop members (16). They are bowed into an arch above their lower ends which are fitted into mounting brackets (20) secured to the corners of the wagon. A spreader rod (22) forces apart the arched portions of the hoop members sufficiently at the top to develop an overhang beyond the ends of the wagon, thereby allowing the lower legs adjustment to any wagon size, and creating internal mutual stresses between the frame and the cover in a modular, unitary structure strengthened thereby enough to avoid having to use intermediate ribs or other support parts.
