摘要

The work bench is preferably made of commercially available metal profile tubes joined only by stable plug-in connections (5,6) welded to end stand elements (1) and two supports (2,3) of the frame in each case but reversibly plugged together without screws. It is structurally stiff to prevent twisting.
