US Patent 7448634 Collapsible display rack

A display rack has a longitudinal axis, and includes vertically stacked and coextensive grid members that are removably connectable. Each grid member has a pair of oppositely spaced arms equidistantly spaced from and parallel to the axis and further includes a mesh patterned central body that spans across a distance between the arms. A mechanism is included for supporting the grid members at both a vertically stacked position and a vertically non-stacked position. The grid member supporting mechanism is completely detachable from the grid members and is independently transportable therewith. The arms are connected to each other when the grid members are stacked and are disconnected when the grid members are not stacked. Selected arms have male and female portions. The male portions are telescopically conjoined with the female portions when the grid members are stacked.
