Abstract
Abstract A support rack having a main frame and workpiece support hooks on which workpieces are hung for transporting through a finishing system. The rack has a plurality of horizontal, vertically spaced crossbars each constructed of a U-shaped, downwardly opening channel member having a pair of side panels and a cross web connecting the panels extending between and longitudinally along the panels. A plurality of crossbeams, at least one near each end of each crossbar, extend between the panels and are spaced below the cross web. A plurality of manually removable sidebars extend between the adjacent vertically spaced ends of the crossbars. Each sidebar has a hook-shaped upper end for hanging over an upper one of the crossbeams and a lower, inwardly bent leg which extends along the underside of the cross web and above the crossbeam of a relatively lower crossbar to a downturned tip. A removable retaining means is inserted between each of the lower legs on the sidebar and its associated crossbeam for extending from the crossbeam to the leg for preventing significant movement of the leg and for interfering with the downturned tip to prevent withdrawal of the leg from the sidebar.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
186 words
A support rack of the type having a main frame and workpiece support hooks on which workpieces are hung for transporting the workpieces through a finishing system, said rack, in an operable position, including: (a) a plurality of generally horizontal, vertically spaced crossbars each having opposed spaced panels, a cross web extending between and longitudinally along said panels and at least one crossbeam near each end of each crossbar extending between said panels and spaced from said cross web; (b) a plurality of manually removable sidebars extending between the adjacent, vertically spaced ends of said crossbars, each sidebar having an upper end for hanging over an upper one of said crossbeams and a lower, inwardly bent leg extending along the underside of a cross web and above a crossbeam of a relatively lower one of said crossbars to a down turned tip; and (c) removable retaining means inserted between each of said lower legs and its associated crossbeam for extending from said crossbeam to said leg for preventing significant movement of said leg and interfering with said turned down tip to prevent withdrawal of said leg.
