Abstract
Abstract A book and magazine display rack includes a rotatable vertical hollow square shaft having vertically spaced pairs of transversely aligned openings engaged by respective positioning bars. A rack member rests on each bar and rotates with the shaft and includes an upwardly directed rectangular projection and downwardly outwardly inclined base walls extending from the projection bottom edges and terminating in upwardly directed peripheral walls. A transverse vertical partition wall abuts each projection end wall and includes bottom depending tabs engaging slots in the base wall and an inwardly directed projection having a depending tab engaging a slot in the central projection top wall. A rectangular wire frame has legs above the peripheral walls and one pair of frame opposite legs engages recesses in the partition walls and has stops engaging the walls. A coupling section with a square coupling opening aligned with a similar opening in the top wall registers with the projection bottom opening and is tab and slot locked therein, the shaft engaging the square openings with the coupling section resting on a respective bar.
