ABSTRACT:
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 lower ends of vertical tubes to permit pivoting rotation of the corner structure relative to one but not the other of a pair of frame sections coupled thereby. Each of the upper 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 vertical flexure. At the same time, the shaft which is secured to the vertical tube of the corner assembly, and the cap which is non-rotatably coupled thereto, are prevented 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 corner structure. The front sections at opposite ends of the hinged frame structure have upper and lower tubes which terminate at vertical tubes to which such upper and lower tubes are coupled by elbows.
