On two opposite plate sides (2,4) of the casing (1), corner-forming edges are provided which have a longitudinal profile bent shape so that they enclose the corresp. square upright profile (8). They also have a longitudinal flange (9) which is located in a plane parallel to the side (10) of the corresp. profile bent shape, allowing the plate sides to be fixed by the bent shapes being pushed downwards over the respective square cross-section profile. The two other flat plate sides (3,5) of the casing rest on the base (6), and are pushed inwards between two corner forming edges, supporting against the flanges (9) of the profile bent formations. The casing cover (7) has an edging (12) which fits over the upper edges of the four sides, holding them together. |
