Publication number: 20210259430Abstract: A folding bed frame that includes four vertical faces: two ends and two sides. Each face is formed by two slanting bars that are cross hinged together. The upper and lower ends of adjacent slanting bar sets are hinged together to form the whole frame structure. The two vertical faces are corresponding or symmetric, and each includes two sets of slanting bar sets that are hinged through to middle sections of the upper and lower angle plates. There is a vertical rod part on the cross-hinging point of each set of slanting bar set, and its movable position is set by a slide bushing. There is a barrier that is on the cross-hinging point of one of the slanting bars. The barrier can contact the upper part vertical bar, and form two support points with the slide bushing for the vertical bar part.Type: ApplicationFiled: February 24, 2020Publication date: August 26, 2021Inventors: Andrew David Frankel, Shi-Ping Zheng, Tian-Xia Zheng
