Revoluble tiered bin stand

Claim 1

In a display stand including a support pedestal, vertical shaft means rotatably supported on said pedestal, a series of vertically-spaced basket-like bin means, each said bin means consisting essentially of a plurality of sector-like trays disposed to abut one another laterally along radially extending side margins thereof, said trays being circumferentially arranged so as completely to encircle said shaft means, securement means detachably fastening said bin means as a tier in a tiered array on said shaft means for rotation therewith, said securement means comprising a pair of vertically spaced probes constituting rod-like projections unitary with each tray at radially inward extremities of each tray, said projections on each tray being disposed normally to one another with a first projection extending substantially parallel to said shaft means and a second projection extending substantially perpendicular thereto, each projection being adapted to penetrate into and to seat within a corresponding aperture formed in said shaft means, thereby to secure each tray detachably thereon, tray intercoupling means mechanically interlocking adjacent trays of each tier to one another at side margins thereof to stabilize and brace each tier of the tiered array, said intercoupling means consisting essentially of an L-shaped flange including a horizontally projecting rod-like support and an integrally formed upwardly directed area, means fastening said flange to extend laterally outwardly from a lower framing element of each one of said trays, said flange defining an upwardly opening slot receiving therewithin a lower framing element of an adjacent tray, whereby said flange serves both as an auxiliary support for an adjacent tray and as interlock means for contiguous trays of each tier; the improvement wherein said display stand further comprises a header card and connector means for mounting said header card on said shaft means to extend upwardly therefrom, said connector means comprising a web joined to and depending downwardly from said header card, said web being dimensioned laterally to provide a sliding fit of said web downwardly into an axial opening formed at the top of said shaft means, said web having a radially directed slot extending inwardly from an outer edge of said web, and a web-coupling washer dimensioned to be received within said shaft means and to extend transversely thereof therewithin, said washer being formed with a radially inwardly directed slot adapted matingly to receive said web of said header card therewithin as said washer is simultaneously received within said web upon intercoupling of said web with said washer at respective slots formed therein, thereby to stabilize said header card against axial tilt upon insertion of said web with the intercoupled said washer into said shaft means.
