Abstract:

Open frame shelving includes upright posts including corner posts and center posts, single-depth and double-depth shelves, horizontal shelf supports and backstops. The corner posts have open, box-like, transverse cross sections with rectangular vertically spaced slots in the end walls thereof and with tapered, vertically spaced slots in the spaced inner walls thereof. Each shelf support has tabs at the opposite ends thereof projecting perpendicular to the axis and engageable in the tapered slots of the corner posts. Backstops extend parallel to the shelf supports and have tabs at their opposite ends engageable in the rectangular slots in the corner posts or in similar slots in the center posts. Single-depth shelves are supported between a shelf support and a backstop, and double-depth shelves are supported between two shelf supports, and may be provided with a reinforcing bar extending between the shelf supports. The arrangement permits a double-depth, double-entry configuration with single-depth shelves at staggered levels and double-depth shelves, and with unobstructed pass through on the double-depth shelves.
