Abstract (en)

[origin: EP0892123A2] The supports comprise extruded hollow profiled sections (10-13) of rectangular cross-section of different cross-sectional length and width with the cross-sectional length of one hollow section corresponding to the cross sectional width of the associated other hollow section. The ratio of length to width is between 1.2 and 2.4 At least two opposite profiled sides (18,19) each have a pair of rear cut longitudinal grooves (28) and each groove adjoins a channel-like profiled cavity (24,40) associated with each profiled corner (16).
