Rigid chain system for articles with column structures

In a load supporting structure having a horizontal element interconnected with a rigid vertical column having a plurality of chain-like link sections, wherein adjacent link sections are aligned with perpendicular planes intersecting along a common column axis, each of the link sections comprising solid leg portions and separate bridging portions rigidly interconnecting the leg portions at opposite longitudinal ends thereof, the bridging portions of adjacent link sections being formed as an integral bridge element made of a single unitary piece of material, and means for holding the leg portions rigidly assembled to said bridge element parallel to the common column axis.

In a load supporting structure having a horizontal element interconnected with a rigid vertical column having a plurality of chain-like link sections, wherein adjacent link sections are aligned with perpendicular planes intersecting along a common column axis, each of the link sections comprising spaced leg portions and separate bridging portions interconnecting the leg portions at opposite longitudinal ends thereof, the bridging portions of adjacent link sections being formed as an integral bridge element made of a single unitary piece of material, and means for holding the leg portions assembled to said bridge element, each of said bridge elements having four coupling faces, the leg portions interconnected by the bridge element having end faces engageable with said coupling faces, and coupling means extending between said bridge element and the leg portions through each of said engaged coupling and end faces.
