Abstract

The frame system, especially for racks and interior fixtures comprises elongate lattice girders, including three chords not disposed in one plane and interconnected in transverse direction by ties. The ties are so arranged with respect to the chords that their legs define the sides of regular pyramids having square bases. Each of the pyramid surfaces is suitable for the connection of two lattice girders.
