Abstract
The present invention provides a rotatable tower for holding and displaying books, video cassettes, and like articles on a plurality of square shelves which extend in horizontal planes and are supported in vertically spaced relation to one another by a plurality of vertically extending rods, groups of which are interconnected into L-shaped configurations by L-shaped, horizontally extending rods. The shelves include an elongated slot formed from the midpoint of each edge inwardly towards the shelves' geometric center, and two laterally spaced notches formed in each edge to one side of the slot. Each edge of the shelves includes a downwardly extending flange along their entire lengths and an upwardly extending flange along a portion of the length to the opposite side of the slot in which the notches are formed. Each L-shaped group of vertically extending rods is comprised of four rods, two rods forming each leg of the L. The rods in each group are spaced from one another a distance corresponding with the length and spacing of the slot and notches formed in each edge, thereby permitting one group of rods to engage the slot and notches formed in each edge of each shelf. Each shelf can …
