Claim:
A modular display rack unit comprising: a first tray and a second tray, wherein each one of said trays comprises a left tray panel, a right tray panel, a front tray panel, a rear tray panel, and a bottom tray panel; a first pillar, a second pillar, and a third pillar; wherein each one of said trays further comprises a plurality of ports, which ports can be described more specifically as: a front pair of ports on the left and right tray panels; an upper rear pair of ports on the left and right tray panels; a lower rear pair of ports on the left and right tray panels; an upper pair of ports on the rear tray panel; a lower pair of ports on the rear tray panel; wherein the front pair of ports on the left and right tray panels, the upper rear pair of ports on the left and right tray panels, together with the upper pair of ports on the rear tray panel, define a plane that parallels the bottom tray panel; wherein the front pair of ports on the left and right tray panels, the lower rear pair of ports on the left and right tray panels, together with the lower pair of ports on the rear tray panel, define a plane that forms an acute angle with a plane containing the bottom tray panel; wherein each one of said pillars has a plurality of lateral pairs of ports, and said lateral pairs of ports are distributed across the length of each pillar; wherein the second tray is aligned above the first tray, and the first and second trays are spaced apart and secured in their relative positions by shared attachment to the first, second, and third pillars such that: the first pillar is adjacent to the trays' left tray panels; the second pillar is adjacent to the trays' right tray panels; and the third pillar is adjacent to the trays' rear tray panels; wherein said shared attachment is accomplished by installment of a plurality of pushpin fasteners through appropriately-aligned sets of the ports on adjacent trays and pillars; wherein each of said ports comprises a hole for receiving said pushpin fasteners; wherein each of said trays is adjustable between two orientations, a first non-gravitational-feed orientation and a second gravitational-feed orientation; and wherein said orientations are determined by the alignment of the respective pairs of ports of the pillars and a respective tray.
