摘要: A strong, light-weight rack is disclosed which collapses or folds into a compact form for shipping storage and opens to orient plurality of vertically spaced planar shelf members at proper angle variable spacing receive contain carpet swatches like samples goods in convenient, overlapping vertical display. Side portions the as well top are hinged so fold positions shelves articulate collapsed position. As re-oriented relationship, sides foldable engagement with frame rigidify structure.
