Abstract
Abstract A modular display unit for vertically stackably arranging products in inclined gravity feed orientation including a plurality of shelf members having a planar floor portion and a plurality of stacking/socket members located at spaced locations adjacent the opposed side portions thereof, the stacking/socket members being arranged in opposed relationship to the floor portion of each of the shelf members and each having a locating surface oriented at the same acute angle relative to the plane of the respective floor portions, a plurality of elongated support members each having opposed end portions adapted to cooperatively engage a respective locating surface associated with the stacking/socket members on adjacent shelf members for connecting the adjacent shelf members in spaced apart relationship, and a plurality of base support members supporting the connected shelf members on a horizontal surface with all of the support members oriented in a vertical direction. Various assemblies for elevating the rear portion of a substantially flat shelf member supported on a substantially flat shelf display area associated with many known modular display units so as to achieve a gravity feed orientation as well as several embodiments of a multi-shelf gravity feed display unit are likewise disclosed herein.
