DEFINITION
Classification: 211/191
(under subclass 190) Device wherein the framework is constructed of at least two connected sets of interconnected members each interconnected set including two vertically-disposed members and a horizontally-disposed member connected adjacent each of its two ends to one of the two vertical members, and one interconnected set being connected to a similar interconnected set spaced therefrom, whereby the horizontal members of two spaced sets of members form an article support, and wherein the horizontal members are repositionable in an up-and-down direction relative to their vertical members.
(1) Note. In practice, one vertical upright may be a common support for a plurality of horizontal beams so that a plurality of interconnected sets may be connected together using fewer uprights than the number of interconnected sets.
