Abstract
A frame structure assembled from frame limbs for a switch gear cabinet, in which the frame limbs are preferably designed in mirror-image like manner in relation to their cross-sectional diagonals and in the interior region of the frame structure comprise two receiving formations, having fastening rebates for fastening mounting rails. The receiving formations are orientated parallel to associated exterior sides of the frame structure. The interconnection of frame limbs and mounting rails is simplified and improved because the receiving formations pass into terminal sections, bent over once or twice, forming an open dovetail groove or a closed dovetail groove for fixing the mounting rails that have appropriate engagement formations.
