A children's play structure includes a hinged frame structure having mounted thereon a plurality of panels depicting murals or scenes. The hinged frame structure, which is comprised of a plurality of hinging sections and which is of lightweight, simple and economical construction, is provided with substantial rigidity by corner structures which include hinging apparatus at the upper and l ower ends of vertical tubes to permit pivoting rotation of the corner structure relat ive to one but not the other of a pair of frame sections coupled thereby. Each of the u pper and lower hinging apparatus includes a clevis and a lever releasably coupled to the horizontal tubes of the adjacent frame sections by plugs with resilient release tabs. The clevis and lever have interleaved legs which receive a shaft and an opposite cap within apertures therein to permit pivoting rotation between the lever and the clevis while at the same time providing substantial resistance to unwanted verti cal flexure. At the same time, the shaft which is secured to the vertical tube of th e corner assembly, and the cap which is non-rotatably coupled thereto, are prevent ed from rotating relative to the clevis, such that only one of the adjacent hinging frame sections is free to rotate relative to the single common vertical tube of the co rner structure. The front sections at opposite ends of the hinged frame structure hav e upper and lower tubes which terminate at vertical tubes to which such upper and lower tubes are coupled by elbows.
