A modular display rack capable of multi-unit stacking and simultaneously accommodating trays in either a gravitational-feed orientation or a non-gravitational-feed orientation. A preferred embodiment comprises: 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 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.

We claim: 1. 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
We claim: 1. 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. 2. The modular display rack unit of claim 1 wherein each pillar comprises a formed panel material having complementary top and bottom structures for stacking and interlocking two or more pillars vertically, thereby enabling two or more modular display rack units to be stackable. 3. The modular display rack unit of claim 2 wherein said complementary top and bottom structures of each pillar comprise: a) a trapezoid-like shaped portion of the panel material extending from the top of the pillar; b) an upper cylindrical keyhole-containing portion, located within the trapezoid-like shaped portion, that is offset from the rest of the panel material toward an exterior side of the pillar, thereby leaving a cylindrical depression on an interior side of the pillar and a cylindrical protrusion on the exterior side; c) a trapezoid-like embossed boundary, located at the bottom of the pillar; d) a lower cylindrical keyhole-containing portion, within the confines of the trapezoid-like embossed boundary, that is offset from the rest of the panel material toward the exterior side of the pillar, thereby leaving a cylindrical protrusion on the exterior side. 4. The modular display rack unit of claim 1 wherein said trays and pillars further comprise a plurality of surface crossmembers. 5. The modular display rack unit of claim 1 wherein the interior faces of each one of said trays are structurally reinforced by a plurality of interior buttresses, each of which buttresses extends perpendicularly and downward from the upper portion of its respective interior tray face to the interior surface of its respective bottom tray panel. 6. The modular display rack unit of claim 1 wherein the bottom tray panel of each one of said trays defines a plurality of triangular spaces dispersed in alternating orientations throughout the bottom tray panel. 7. The modular display rack unit of claim 1 wherein each one of said pillars comprises a panel material having a plurality of longitudinal, alternating, orthogonal folds. 8. The modular display rack unit of claim 1 wherein each one of said trays further comprises: a tray divider having three prongs; and a plurality of triplets of holes, where each triplet runs parallel to the left and right tray panels. 9. The modular display rack unit of claim 1 further comprising a plurality of placard holders.
