Abstract: A mounting frame for a switchgear cabinet or a rack includes mounting pieces which are arranged, as corner pieces, in the four corner sections of a rectangle or square that extends in an x-y plane, the mounting pieces being produced in a respective shaping process and having outer first and second mounting faces which extend in the x direction and in the y direction at a right angle thereto and which extend in a space direction z at a right angle to the x-y plane, and are provided with hollow spaces which are at least partially surrounded by wall parts and/or bores that are oriented in the z direction. The mounting frame further includes intermediate elements which extend between the mounting pieces in the x direction and in the y direction and the end sections of which are fastened to the mounting pieces. The mounting pieces have wall sections which extend in parallel to the x-y plane, thus making assembly easier.

Abstract: The invention relates to a base corner piece for single-handed mounting on a switch cabinet, comprising a supporting portion that can be screwed to a frame profile of the switch cabinet in a mounted position of the base corner piece, and is characterized in that the base corner piece has means for pre-mounting of the base corner piece on the frame profile in the mounted position, comprising means for spatial orientation of the base corner piece in relation to the frame profile and means for releasable latching of the base corner piece to the frame profile.

Abstract: A base assembly for the rack of a switchgear cabinet, comprising horizontal frame profiles which have the height h and which surround a base section of the rack, wherein at the height h, the frame profiles have a first horizontal mounting plane, is characterized in that, spaced from the first horizontal mounting plane, at least one additional mounting plane is provided, on or adjoining a fixed support which is formed at least sectionally on one or more of the frame profiles and projects into the base section.

Abstract: A frame profile for a switchgear cabinet rack has two profile sides perpendicular to one another forming outer sides of the rack, and being in the form of a hollow-profile section. The profile sides transition into one another via transition sections that are perpendicular thereto and a connecting web without formation of an outer edge. The profile sides are adjoined, facing away from the transition sections, by first profile sections which are respectively perpendicular and parallel to the associated profile sides. At least the perpendicular or the parallel first profile sections have a row of fastening receptacles. The perpendicular first profile sections are adjoined by two profile sections which transition into an at least partially rounded contour section, the second profile sections each form with the contour section an undercut of the contour section on the outer side of the profile, and the frame profile encloses a coherent hollow chamber.

Abstract: A base or a mounting frame for an electrical enclosure or a rack, includes mounting pieces which are arranged, as corner pieces, in the corner regions of a rectangle or square that extends in an x-y plane. The mounting pieces are produced in a respective shaping process and include first and second mounting faces which lie outside with respect to the rectangle or square, which extend in the x direction and in the y direction at a right angle thereto and which extend in a space direction z at a right angle to the x-y plane. Sections of a system of covers are brought into contact with the mounting faces, where the covers having lateral covers with cover walls that are flat on the exterior and that have reinforcing ribs extending longitudinally on the interior, and are fastened to receiving structures of the mounting pieces by connecting structure.
