Modular elements for composing frame for the construction of cabinet structures and containers for electrical, electromechanical and electronic components, for internal and external use, wherein said elements form the perimetral cabinet frame defined by section bars (10, 10') and angle pieces (19, 19', 19") connected together; the angle pieces (19, 19', 19") are constituted by a corner portion (20, 20', 20") from which there extend several mutually orthogonal tube portions (21, 21', 21") of substantially quadrilateral cross-section; the section bars (10, 10') are constituted by tubular elements arranged for insertion onto said tube portions (20, 20', 20") and comprising, extending from one corner (11) thereof in mutually orthogonal directions, two flanges (12) from which there extend two further converging flanges (14) from which there extend two mutually orthogonal profiled portions (16) which can be provided with standardized holes (17) arranged for supporting electronic and electromechanical containers.

1. Modular elements for composing frames for the construction of cabinet structures and containers for electrical, electromechanical and electronic components, for internal and external use, said elements forming the perimetral cabinet frame defined by section bars and angle pieces connected together, characterised in that the angle pieces are constituted by a corner portion from which there extend several mutually orthogonal tube portions of substantially quadrilateral cross-section; each of said section bars comprising a tubular element of orthogonal shape arranged for insertion onto one of said tube portions and further comprising, extending from one corner thereof in mutually orthogonal directions, two flanges from which there extend two further converging and intersecting flanges, from which intersection there extend two mutually orthogonal profiled portions being provided with means arranged for supporting electronic and electromechanical containers. 2. Elements as claimed in claim 1, characterised in that the intersection of said second mentioned flanges defines a point on a straight line representing the prolongation of that diagonal of the tubular element of the section bar which passes through the corner from which the first mentioned two flanges extend. 3. Elements as claimed in claim 2, characterised in that at their ends each of the flanges are cut along first planes which pass through the sides embracing the corner from which the flanges extend, and which form an angle of 45° with the plane orthogonal to the section bar axis: said first planes intersecting along said straight line. 4. Elements claimed in claim 1, characterised in that said first mentioned flanges extending from the tubular element comprise end edges bent parallel to those sides of the tubular element which define said corner. 5. Elements as claimed in claim 1, characterised in that the first and second mentioned flanges and the profiled portions with standardised holes extend from two adjacent corners of the section bar. 6. Elements as claimed in claim 5, characterised in that the two facing flanges of the first mentioned pair of flanges mate over a first portion which extends from the tubular element. 7. Elements as claimed in claim 5, characterised in that the two facing flanges of the first mentioned pair of flanges lie on said straight line. 8. Elements as claimed in claim 1, characterised in that the tube portions of the angle piece are hollow. 9. Elements as claimed in claim 1, characterised in that the tube portions of the angle piece are longitudinally slotted.
