| 摘要 | A folding wall assembly comprising a plurality of upright panel sections disposed in edge-to-edge relation and pivotally secured together along adjacent upstanding edge portions for relative horizontal swinging. The panel sections include upstanding rod portions defining the adjacent edge portions thereof and the latter are pivotally secured together by means of vertically spaced sleeve members through which both corresponding rod portions of the adjacent panels are loosely received. Each panel section is defined by a plurality of side-by-side upstanding rod members interconnected by a plurality of vertically spaced generally horizontal rod members crossing and secured to the vertical members and the corner portions of the panel sections are reinforced by vertical extensions of the vertical edge defining rod bent approximately 180* inwardly and back upon themselves and anchored to the adjacent horizontal rod member end portion. | ||||||
| 权利要求 | 1. A portable free standing upstanding barrier assembly including a plurality of upstanding panel sections each including upstanding opposite side edge portions, said panel sections being disposed in upstanding side edge-to-side edge relation, each panel section comprising a grid of crossed upstanding and horizontal elongated members secured to each other, the upper and lower ends of the upstanding elongated member at each side of each of said panel sections including an endwise extension smoothly bent inwardly toward the other side of the panel section and back toward the remote end of the panel section and secured to the adjacent horizontal member a spaced distance from that upstanding elongated member, and means joining adjacent side elongated members of adjacent panel sections to each other for relative swinging of said adjacent panel sections about upstanding axes. 2. The combination of claim 1 wherein said means comprises a plurality of vertically spaced sleeve members loosely receiving corresponding portions of said side upstanding elongated members therethrough. 3. The combination of claim 2 wherein said sleeve members are each retained captive on the corresponding upstanding elongated members between a pair of said horizontal members. |
