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.

1. A collapsible canopy adapted to be deployed as a removable top on a child's wagon covering a range of commercially available bed sizes comprising:a frame having convertible states, one an erected state and the other a collapsed state, said frame having a pair of hoop members in opposed relationship to each other, spaced apart in the erected state corresponding to a given bed size range on which the canopy is to be mounted , and spaced adjacently together when removed from the wagon in the collapsed state to form a compact, relatively flat frame for ease of storage or shipment, said hoop members each having lower leg portions joined by an arched central portion, the leg portions in the erected state being adjustable longitudinally within the range of bed sizes and adapted to be mounted adjacent opposed ends of any of several wagon beds within said range of sizes, a flexible covering material having bordering edges defining a relatively elongated continuous surface area, which in the erected state takes its shape from the opposed hoop members as a relatively high arched canopy over the entire wagon bed with the arched portions and lower leg portions of the hoop members capable of applying tension to the elongated surface area sufficient to make it taut without intermediate transverse supports in the erected state, and mounting means for removably attaching the leg portions of each hoop member adjacent opposed ends of a wagon bed in a given range of sizes being mutually spread apart by the act of attaching them to cause the tensioning of the surface area in the erected state.
