Abstract
An equipment rack has horizontal frame structure, and vertical frame structure of sheet material, secured to that horizontal frame structure and having a bent cross-section and opposite ends. The bent cross-section has a square-wave configuration including alternate first, second and third square half-cycle configurations in one piece presenting three substantially flat and mutually spaced crests. The horizontal frame structure extends into more than one of these square half-cycle configurations and along the substantially flat crests of the latter square half-cycle configurations in overlapping relationship with the vertical frame structure substantially for the widths of the crests and for corresponding heights of the horizontal and vertical frame structures. The horizontal and vertical frame structures are intimately interconnected along the above mentioned opposite ends and at all overlapping portions of the horizontal and vertical frame members.
