Hollow foam plastics floor component - has recesses in one edge and bosses on opposite one

摘要

The floor component is of honeycomb foam plastic, and has cylindrical recesses extending from one edge for a length which is several centimetres less than its own. The opposite and blind edge has bosses (5) fitting in the ends of the recesses in the adjacent component (1). The bosses can be cylindrical and of shape approximating to that of the recesses, and can be several centimetres long. The end of the component not containing recesses can have a reinforcing insert of metal, wood or plastics extending in the transverse direction, or alternatively there can be such an insert at each end, extending as far as the component supports.
