Abstract

This invention relates to a rotary storage cabinet comprised of an outer stationary housing and an inner rotatable rotor having four sides two of which are positionable to present the contents of the cabinet simultaneously to two opposite openings in the housing. Two other opposite sides of the rotor are positionable to close the openings in the housing. The cabinet is constructed from a plurality of sub-assemblies which are shipped for assembly at the point of use. The basic structure of the unit comprises a base (20), two pilaster frames (10), and a top frame pan (30) each of which is shipped as a sub-assembly. The cabinet includes several features including: the ball bearing mechanism (FIGS. 7-9); spring urged wheel (180) and detent (150) (FIG. 12) stop mechanism; lock mechanism (160) (FIG. 12); welded pilaster frames (10); and a single centrally located rotor frame (50). The unit is modular permitting the use of like "add-on" units (FIGS. 16 and 17).
