This has a curved groove to fit on to a tubular support(5). The shelves are held in place by screws(16) fitted through the shelf and the assembly element into the support. The curve of the groove is smaller in radius than the exterior curve (4) of the support. A thin annular padding(13) with a conical peripheral surface is fitted into the groove around the screw hole.</p> |
