Abstract:
1. Storage and display shelf apparatus for positioning on a support structure comprising: a pair of guide tracks supported in spaced parallel relation for mounting on the support structure, said guide tracks having a front end portion and a rearward end portion, a plurality of guide wheels supported by said guide tracks, an assembly of shelves positioned one behind the other extending from a front shelf to a back shelf between said guide tracks, each of said shelves having a receptacle for receiving an item to be stored and displayed, a set of guide wheels carried on each of said shelves for engagement with said guide tracks for movement of said shelves between said guide tracks front and rearward end portions from a stored position on said guide tracks to a display position relative to said guide tracks, each of said shelves having a boss extending from opposite sides thereof in alignment with a boss extending from opposite ends of an adjacent shelf, a hinge pin extending through said aligned bosses to connect adjacent shelves, a spring surrounding said hinge pin and positioned between said aligned bosses to exert an upward biasing force upon said shelves when positioned on said guide tracks, a trunnion extending outwardly from an upper end of said hinge pin above said aligned bosses, a link arm positioned on each side of said assembly of shelves extending parallel to said guide tracks, said link arm having a front end and a rearward end with a series of spaced apart slots extending between said front end and said rearward end, said link arm rearward end being pivotally connected to said rearward shelf, said trunnion of said hinge pin positioned in said respective slot of said link arm to connect said link arm to said shelves, and said link arm being pivotal on said rearward shelf upon movement of said assembly of shelves from the stored position on said guide tracks to the display position where said shelves move off of said guide tracks and said trunnions move forward in said link arm slots so that each shelf forward of said back shelf drops down to a vertically displaced position, compressing the springs where each self is maintained at a different height on said link arms in a tiered arrangement of said shelves.
