摘要： Mounted within a square storage cabinet is a tier of revolving shelves each shaped generally as a three-quarters circle having a diameter approximately equal to the square dimension of the cabinet to avoid wasted space in the cabinet. Each shelf is formed with one straight edge located to enable tiers of trays attached to two swinging cabinet doors to be made of an optimum depth permitting the trays to fill the space between the shelves and the doors when the latter are closed. Detent mechanisms hold the shelves in centered positions within the cabinet and resist any tendency of the shelves to spin uncontrollably when turned out of the centered positions. The door trays are hooked detachably onto standards fastened to the inner sides of the doors and are constructed to avoid leaving objectionable gaps between the doors and the trays.
