Definitions
- This invention relates to a demountable floor tile and relates particularly but not exclusively to one which can be used to interlock with identical floor tiles and be used to protect ground surfaces such as grassed sporting grounds, internal floors in buildings, and the like.
- demountable floor tiles have been used to temporarily protect ground/floor surface during the holding of special events, such as music concerts, exhibitions, and the like. After the event the floor tiles can be demounted from each other and the ground/floor returned to its former status. Rectangular floor tiles are known, as are other shaped floor tiles.
- the known tiles have poor structural torsional rigidity which means that the tiles as a group when laid on a floor tend to twist with respect to each other and then the whole floor assembly of interlocked tiles buckles and this looks unsightly and can result in a potential uneven flat floor surface and can give rise to the possibility of persons tripping when walking on the tiled floor surface.
- a rectangular shaped plastics material demountable floor tile which has a tongue extending along one side of a and a complementary tongue receiving channel extending along the opposite side for receipt of the tongue of an adjacent floor tile and for permitting interlocking of the adjacent tile, the floor tread surface of the tile between the tongue and the channel being provided by two rows of rectangular upstanding block parts each separated by a central longitudinally extending channel and each separated from the respective adjacent tongue or channel by respective longitudinally extending side channels, there being laterally extending strengthening flanges extending between a wall defining the tongue channel, said flanges being greater in number than two, and there being laterally strengthening further flanges extending in the channel between the two block parts, said further flanges being greater in number than two.
- the height of the flanges and the strengthening flanges is greater than 50% of the depth of the channels.
- Figure 1 is a top view
- Figure 2 is an underneath view
- Figure 3 is a top perspective view
- Figure 4 is an underneath perspective view
- Figure 5 is a cross sectional view taken along section line A-A of Figure 1.
- Figure 6 is a cross sectional view taken along section line B-B of Figure 1.
- a demountable floor tile 1 made from a suitable plastics material, such as polyethylene polypropylene or the like, and made by an injection moulding process.
- the tile 1 has an upper tread surface 2 and an under surface 3.
- the tile has a rectangular footprint.
- a longitudinally extending tongue 4 extends along one side edge of the tile and a complementary longitudinally extending tongue receiving channel 5 extends along the opposite side.
- the tread surface 2 is formed by two rows of upstanding block parts 6 and there are longitudinally extending side channels 7 and 8, which separate the tongue 4 and the tongue receiving channel 5 from the block parts 6.
- a central longitudinally extending channel 9 separates the two rows of the block parts 6.
- Strengthening flanges 10 extend laterally across the side channels 7 and 8, and further strengthening flanges 11 extend across the central channel 9.
- these flanges 10 and 11 were only two in number in each channel and their height was less than 50% of the depth of the channel 7, 8 and 9. Accordingly, in the known tiles, poor torsional rigidity resulted.
- On the under surface of the tile we have included 2 central strengthening flanges 12 in each of the under surface areas 13 of the block parts 6. These were not provided in the known tiles, and these new flanges 12 also assist in providing enhanced torsional rigidity to the tile 1.
- the known tile has poor airflow from the under surface 3 because the ventilation openings 14 are only about 50% less than the opening area now provided.
- the area provided for ventilation openings on side walls of the channels 7, 8 and 9 is therefore of an area greater than 50% of the area of a wall part between adjacent blocks 6. This is important for grassed areas to maintain good airflow to prevent damage to the grass, and to control the temperature under the tiles particularly in outdoor environments where the tiles may be subjected to prolonged exposure to the sun and give rise to elevated temperatures under the tiles .
