A cuboid component has triangular grooves (3) in the two side surfaces (1 and 2) and there are triangular projections (6) on the side surfaces (4 and 5). The other two, generally horizontal, surfaces (7 and 8) are flat. The projections (6) fit into the grooves (3), i.e. the triangles are of the same shape and size. It is thus possible to assemble the cuboid components in a wide variety of ways in order to set up presentation or sales surfaces. A composition of the cuboid components is also suitable simply for decorative purposes. |
