Abstract
A rack for holding articles, components, parts and other such items and further being collapsible and stackable upon other similar racks whether any of the racks are in an upright or collapsed position. The rack includes a shelf and a plurality of leg assemblies distributed about the shelf perimeter, the leg assemblies each having a leg footer, a leg member, and a slider pivot bearing joining the proximal ends of the leg footer and leg member thereby constraining relative motion between the leg footer and leg member to two degrees of freedom. Embodiments of the rack further include retaining tabs on the leg member and corresponding notches on the leg footer to lock leg members in the upright position. Pairs of leg assemblies may be connected by primary connecting frame elements forming a portion of the perimeter, with the pairs being connected by secondary connecting frame elements forming another portion of the perimeter.
