Patent ID: 8210362

Claim:
A control box arrangement comprising: at least one control box ( 2 , 3 , 4 ) having a frame ( 10 ) constructed from vertical and horizontal frame legs ( 11 , 12 . 1 , 12 . 2 ) and an interior equippable with mounting parts including mounting rails ( 17 ) to permit a variable subdivision of the interior and having the frame legs ( 11 , 12 . 1 , 12 . 2 ) with rows of fastening holes in a defined pattern, one-piece connecting pieces ( 18 ) for connecting the mounting rails ( 17 ) to the frame legs ( 11 , 12 . 1 , 12 . 2 ) having a coupling section ( 18 . 2 ) protruding at right angles from an attachment plane of the associated frame leg ( 11 , 12 . 1 , 12 . 2 ) when the connecting piece is in a mounted position, the coupling section ( 18 . 2 ) having a square cross section or a rectangular cross section and contains containing at least one transversally extending threaded bore ( 18 . 3 ), and two planes of the coupling section ( 18 . 2 ) oriented parallel to a vertical plane of the control box ( 2 , 3 , 4 ) and two planes of the coupling section ( 18 . 2 ) oriented parallel to a horizontal plane of the control box ( 2 , 3 , 4 ), wherein for connecting horizontally and vertically arranged mounting rails ( 17 ), corner connectors ( 19 ), cross connectors, and/or T-pieces have connecting sections ( 19 . 2 ) that are square or rectangular in cross section and that have cross-sectional dimensions matched to widths of the profile legs of the mounting rails ( 17 ) and have transversely extending threaded bores ( 19 . 3 ) in support surfaces matched to a pattern spacing of the rows of fastening holes.
