Abstract
Abstract A table base (2) features a table substructure (4) and pedestals which can be arranged at its ends. Supporting rails (24) featuring plug-in holes (28, 30, 32, 34) for supporting parts (12, 14) on the pedestal side and for cross-arms (20, 22) on the table base side are arranged parallel to the ends of the table base (2) in the area of connection between the table substructure (4) and the pedestals (6). The connection between the supporting rails (4), the cross-arms (20, 22) on the table base side and the supporting parts (12, 14) on the pedestal side is made in the form of a truss union so that the entire table base (2) is exceptionally stable while having the appearance of a light construction.
