At its outside, the table frame or support is provided with two symmetrical, circular drive paths into each of which a drive wheel engages. Two respective guide rails are arranged at the table frame or support at both sides thereof, two respective, stationary guide pegs engaging into these guide rails in the horizontal position, said guide rails being fashioned and directed or, respectively, curved such that, given adjustment of the tilting table out of the horizontal position, respectively two guide pegs leave their guide rail and the lower end of the table frame or support is lifted to such a degree that it lies above the floor level. The curvature of at least one pair of guide rails at both sides of the table frame or support is selected such that the tilting speed is roughly uniform.
