Abstract
Abstract A working table is described in which the rear support elements are formed as hollow sectional parts in order to achieve the highest possible degree of variability in the provision of working levels and storage levels. Coupling elements which are secured to the surfaces or to transverse support elements are connectable to the hollow sectional parts in shape-fitted and force-locked manner.

Claims Analysis
Total Claims: 17
Claim 1
Independent Claim
213 words
Working table comprising: working surface; first and second front support elements and first and second rear support elements for supporting said working surface; each of said rear support elements comprising a hollow section having a tubular central part with an outer periphery, coupling channels formed on said tubular central part and distributed around said outer periphery, and with at least two coupling flanges which extend along at least a part of said hollow section, said coupling flanges subtending an angle to one another; coupling elements secured to said working surface at a position corresponding to said first and second rear support elements and being complementary in shape to said coupling flanges; means for connecting said coupling elements to said coupling flanges in form and force-locked manner; said coupling channels being orientated in two planes which extend perpendicular to one another and provided with respective projections; and first, second and third cover sections comprising a first planar cover section plate fixable between said coupling flanges, and first and second angled cover sections being fixable in each case between a said coupling flange and a said projection of a said coupling channel, said cover sections together with said hollow section forming a closed hollow section having a cross-section in the form of a right triangle.
