Abstract

Sheet metal convenience store shelving utilizes shelf-supporting frame-modules, each of which comprises a prefabricated frame rigidly connectable to a pair of shoes to provide free-standing units. Shelves are supportable on both sides of the frames, and the rear edges of the shelves are notched to receive the frame uprights. Each frame holds a removable backing panel, and additional backing panels extend between adjacent frames, being held in side channels of the frame uprights. The shelves are mounted on the uprights by the engagement of generally horizontally sheet metal shelf tabs with T-shaped slots in the uprights. The tabs extend laterally almost the full interior width of the uprights for optimum strength. As the shelves extend beyond the frame uprights, provision is made to prevent accidental disengagement due to excess weight on an overhanging part of a shelf. The tab neck is enlarged next to the head, and the lower ends of the T-shaped slots are enlarged to receive the enlarged part of the neck underneath overhanging surfaces. The shelf must be tilted upwardly before it can be disengaged from the slots. Upper and lower tabs associated with a shelf bracket are aligned with each other by first securing a tab to the underside of a shelf, and then locating the bracket with respect to the tab by the interengagement of fingers on the bracket with notches in the edges of the tab attached to the shelf. The second tab is secured to the bracket in a predetermined location established by cooperating locating means. The frame modules may be arranged either in a line, or at right angles so that shelving extends continuously around a corner. A unitary L-shaped sheet metal backing panel is used as a backing at the corner, and is secured to both frames by sheet metal screws.
