Abstract
A device for fastening of attachment elements, such as mounting rails, mounting plates, deposit plates and the like on a frame leg of a switchgear cabinet rack, wherein the frame legs are designed symmetrically in relation to their cross-sectional diagonal line and are aligned with the latter with the diagonal line of the rack. On the inside of the frame legs oriented toward the interior of the rack, the frame legs form a fastening receiver with two fastening profile sides which are disposed vertically in respect to each other and extend parallel to the facing outsides of the switchgear cabinet rack. The frame legs form system fastening receivers in the form of square or rectangular openings and fastening bores and make transitions into additional profile sides having corresponding rows of fastening receivers, which extend perpendicular to the facing exteriors of the switchgear cabinet rack. The fastening elements, which have fastening faces with fastening receivers in three directions respectively extending at right angles to each other, can be connected to the frame legs. The positioning of the same is made easier by specially designed fastening blocks, and connecting possibiliti…
