ABSTRACT:
There is disclosed a storage shelf which is specifically designed for an orderly storage of pails with tapered sidewalls. The shelf is used on a rack with end frames which support longitudinal rails at each shelf level. The shelves of the invention are supported between the longitudinal rails, with their ends resting on ledges which are on the inside surface of each rail. Each shelf is formed of heavy gauge sheet metal having coextensive, sidewalls with inclined inside walls. The height and inclination of the inside walls corresponds to the difference between the top and bottom diameters of the pails. This results in a shelf having inclined sidewalls which center the pails on the shelves, yet which provides minimal clearance between the tops of the pails, from row to row, thereby achieving automatic alignment of the pails without increasing the overall size or bulk of the storage unit. Each shelf is braced by its sidewalls and by a central longitudinal rib on its undersurface. To adapt the shelf to fit conventional racks, an angle is placed transversely on each end, thus locating the shelf beneath the top edge of the rail at a distance equal to the height of the sidewalls of the shelf. Also, in a preferred embodiment, a cross wall is provided medially of the shelf.
