Abstract
Abstract A supporting framework for a control cabinet is configured of side frames and cross-beams. The side frames are made of whereby profile elements having a rectangular cross-sectional. The cross-beams possess a square cross-sectional shape that is beveled on one side, and includes two sections at right angles to each other and dimensioned to be of a length corresponding to the longer rectangular side of the cross-sectional shape of the side frame element. The supporting framework is both stable and inexpensive. The cabinets can be attached to one another.

Claim 1
Independent Claim
275 words
A supporting framework for a control cabinet, comprising: (a) frame elements of a first type for use as side frame pieces, said side frame pieces forming side frames of the control cabinet, said frame elements of the first type having a generally rectangular cross-sectional form comprising longer inner and outer lateral sides and shorter front and back sides, and an opening in the inner, longer side defined by two shanks; said side frame elements of the first type further having at least two flat surface sections provided on the longer outer lateral side opposite said opening, said flat surfaces lying on parallel, spaced apart planes separated from each other by at least one indentation, said at least two flat sections being disposed one behind the other, one of the flat sections being contiguous with one of the front and back sides; (b) frame elements of a second type for forming cross-beams of the control cabinet, said frame elements of the second type connecting said side frames to each other, said frame elements having a generally square cross-sectional form beveled on one corner and comprising: a first pair of orthogonal sections of equal length as wide as the longer lateral sides of the side frame elements; a second pair of shorter sections, each shorter section being adjacent and orthogonal to one of the first pair of orthogonal sections; shanks contiguous with the shorter sections set at an angle of approximately 45° with respect thereto, and which define an opening therebetween; and (c) tracks of holes within at least one of said first and second type of frame elements for mounting covering panels, doors, and built-in units.
