Abstract: The invention relates to a table which has variable dimensions, especially a long length, and is mainly used in offices and conferences. The base of the table is supported by feet (6) and carries table leaves (1,1) which are brought together at the longitudinal sides thereof, and an insert (8,81) which can be inserted in-between said leaves, can have different configurations and can be used as a support for various structures. The base of said table comprises at least two transversal supports (2) provided with a central sunken channel region (20) from which two extension arms (21) respectively extended in opposite directions, the feet (6) being mounted on said arms, and lateral struts (4) supporting the table leaves (1,1) being arranged on the outside. The transversal supports (2) are interspaced in a parallel manner, perpendicularly in relation to the longitudinal direction of the table.

Abstract: The invention relates to a table which is primarily used as an office or conference table, is longer than 2.5 m, and comprises an upwardly open trough (2) as a substructure which is arranged beneath the leaf (1) of the table and preferably consists of sheet metal which is e.g. 2 mm thick. The leaf of the table (1) is connected in a fixed manner to edges (25) which are bent away from the trough (2), creating a sandwich-type structure with mutual reinforcement of the leaf (1) of the table and the trough (2). Especially advantageously, the trough (2) has a trapezoidal cross-section. A grid of openings (210) in the trough (2) enables the feet (4) of the table to be mounted in any position. Additional appliance openings (211) are used to insert socket units (80), while installation openings (200) in the bottom (20) of the trough (2) as used as cable ducts. A height leveling device is provided in each foot (4).
