Plastics assembly element for shelving - has curved groove to fit on tubular support and held by screws

摘要

The shelving is for use in refrigerated rooms and consists of shelves with turned up edges(6) and with a plastic assembly element at each corner. 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.
