TITLE

SUPPORT FOR PAVING OR DECKING FIELD OF THE INVENTION The present invention relates to a decking tile.

BACKGROUND ART Existing decking tiles are typically formed of plastics material and are arranged to receive wooden slats layed in a side-by-side manner, with the slats connected thereto by screws or similar fasteners. Such decking tiles are used for a variety of purposes, including providing flooring for outdoor pavilions and balconies.

One type of decking tile currently available is divided into a 4x4 grid, with holes for fasteners provided centrally in the outer most 12 parts. Such tiles are designed to have four slats provided along rows or columns of the 4x4 grid.

Consequently, the middle two slats will have only two fasteners holding the slat to the tile, at opposite ends of the tile. The principal problem with this form of tile is that if a portion of the tile is cut away to accommodate a permanent fixture where the tile is layed, some of the slats may have only one fastener to retain it to the tile, with the result that the slat tends to rotate, impairing the visual appearance of the tile. A secondary problem with this form of tile is that the locking mechanism has a female part provided on two sides and a male part provided on the other two sides of the tile, such that each side of any tile can connect to only two sides of another tile. Where it is desired to form patterns with the wooden slats, the arrangement of the holes for the fasteners and the requirement that each tile can be connected to only one of two sides of any other tile places restrictions on the types of patterns that can be formed.

WO 99/36638 PCT/AU99/00027 -2- Another type of existing decking tile is divided into a 2x2 grid, with four holes forming a diamond provided centrally within each quarter of the tile. The tile is arranged to receive four slats layed in a side-by-side manner on the tile, with each quarter receiving one half of two slats. The apertures are provided such that when the slats are layed parallel to a side of the tile, only two holes in each quarter are useable, with the other two provided in the gap between adjacent slats. The provision of the holes in a diamond pattern allows the slats to be placed parallel to any side of the tile while still providing a hole for a fastener for each slat in each quarter. If one of the quarters is removed from such a tile, two slats would then have only one fastener to hold them to the tile, again presenting problems regarding the rotation of slats on the tile. Further, the arrangement and number of holes for fasteners restricts the types of patterns that can be formed with the slats.

DISCLOSURE OF THE INVENTION In accordance with one aspect of this invention, there is provided a decking tile divided into a plurality of portions arranged in an array, said portions being connected to adjacent portions via a plurality of membranes, each portion being removable from said tile upon severing of the membranes surrounding it, each portion arranged to receive at least two fasteners to secure a slat thereto, wherein said at least two fasteners can engage a slat positioned parallel to any side of said tile.

BEST MODE(S) FOR CARRYING OUT THE INVENTION The first embodiment is shown in figure 1 and is directed towards a decking tile 10 formed by a plastics injection moulding process.

The decking tile 10 comprises sixteen portions 12 arranged in a 4x4 array. Each portion 12 is defined by a wall 13 extending around its periphery and is connected to adjacent portions by a plurality of membranes 14. Accordingly, any of the portions 12 can be removed from the decking tile 10 by severing the membranes 14 surrounding it. This allows the decking tile 10 to accommodate permanent fixtures such as pipes and pillars where the decking tile is layed.

Each of the portions 12 is square in shape and includes two reinforcing members 16 extending diagonally from corner to comer, such that the reinforcing members 16 form an shape.

WO 99/36638 PCT/AU99/00027 -7- An inwardly directed flange 18 is provided on the wall 13 of each portion 12 to increase the structural strength of the decking tile One of the reinforcing members 16 in each portion 12 has a pair of feet formed integrally therewith, one to either side of the other reinforcing member 16. Each of the feet 20 comprises a cylinder 22 having a relatively narrow section 24 formed integrally with the reinforcing member 16 and a relatively wide section 26 extending beyond the reinforcing member 16 so as to protrude from a lower surface of the decking tile 10. The cylinder 22 has an aperture 28 formed axially therein. The aperture 28 has a widened section (not shown) formed in the relatively wide section 26 of the cylinder 22. The aperture 28 is arranged to receive a fastener to retain a slat to an upper surface 30 of the decking tile In this regard, the widened section- of the aperture 28 is intended to receive a widened portion of the fastener, such as the head of a screw. Figure 1 is a plan view looking onto the upper surface 30 of the decking tile Eight of the portions 12 are sub-divided into two sub-portions 32 along the reinforcing member 16 of the portion 12 which does not have the feet 20 formed integrally therewith. Such portions have two reinforcing members 16 provided spaced apart adjacent the diagonal along which the portion is sub-divided. The two reinforcing members 16 are separated by further membranes 34 which can be used to sub-divide the portion 12. Such portions also include further inwardly directed flanges 36 provided on each reinforcing member 16. The sub-divided portions 12 are arranged in the decking tile 10 to allow it to be divided along a diagonal thereof.

The decking tile 10 includes a plurality of guides 38 provided at spaced locations around the periphery of the decking tile 10. The guides 38 extend upwardly of the upper surface 30 and assist to retain slats placed upon the upper surface prior to fastening the slats to the decking tile 10 in that they prevent the slats from extending beyond the periphery of the decking tile WO 99/36638 PCT/AU99/00027 -8- The decking tile 10 further comprises connecting means provided at each side of the decking tile 10 to allow the decking tile 10 to be connected to any side of an adjacent decking tile. In the embodiment, the connecting means comprises first and second components 40 and 42, respectively, with two first components and two second components 42 provided on each side of the decking tile 10 in an interlaced manner.

Each first component 40 comprises a pair of first arms 44 provided spaced apart and having an inwardly directed portion 46. The inwardly directed portion 46 is spaced from the side of the decking tile Each second component 42 comprises a pair of second arms 48 provided spaced apart. A reinforcing member 50 extends between each pair of second arms 48. Each second arm 48 has an outwardly directed portion 52 provided spaced from the side of the decking tile 10. The outwardly directed portion 52 of each second arm 48 and the inwardly directed portion 46 of each first arm 44 are spaced an equal amount from the side of the decking tile 10 and are of substantially equal thickness. To connect two adjacent tiles together, the tiles are placed adjacent each other with one tile slightly above the other, which is then lowered to bring the first and second components on the adjacent sides of the tiles into a mutually engaged position with the first arms 44 of each first component 40 engaged with the second arms 48 of each second component 42.

The decking tile 10 is symmetrical about axes AA and BB shown in figure 1, allowing any side of a decking tile to be connected to any other side an adjacent decking tile.

The reinforcing member 50 in each second component 42 increases the strength of the engagement between the first and second components 40 and 42 by resisting the tendency of the second arms 48 to be forced together if two connected tiles are pulled apart.

WO 99/36638 PCT/AU99/00027 -9- The width of the guides 38 are half that of the first and second components and 42, so that when two decking tiles are connected together, their guides 38 are touching. Further, the width of the first and second components 42 is the same as the distance between the walls 13 of adjacent portions 12, such that when decking tiles are layed in an array, the joints between tiles are not prominent.

The decking tile 10 of the first embodiment was originally intended to receive four wooden slats provided parallel to a side of the decking tile along rows or columns of the portions 12, such that each wooden slat occupied four portions 12. In this regard, it is to be noted that the arrangement of the apertures 28 in each portion 12 permits both apertures 28 in each portion 12 to be used to retain a slat thereto if necessary. This is advantageous since if some of the portions 12 are removed from the tile to accommodate a permanent fixture, the slat positioned on that row or column will also be divided an may have only one portion 12 to retain it to the decking tile 10. The ability to have two apertures in each portion 12 retain a slat prevents rotation of a slat even if that portion 12 is the only portion retaining the slat.

In addition, the incorporation of the apertures 28 into the feet 20 produces an even distribution of the feet throughout the decking tile which provides for a more even distribution of weight placed on the decking tile.

In addition to the above it has been found that having each portion able to receive at least two fasteners provides significant flexibility regarding forming patterns with the wooden slats, to be described hereinafter in relation to the second embodiment. Such patterns were in the main not possible with previous decking tiles because of the arrangement and location of fasteners on those decking tiles.

WO 99/36638 PCT/AU99/00027 The second embodiment is shown in figures 2 to 7 and is directed towards a decking tile 60. The decking tile 60 is similar to the decking tile 10, with like reference numeral denoting like parts.

In the decking tile 60 of the second embodiment, the further flanges 36 are provided on every reinforcing member 16, including those in portions 12 which are not sub-divided.

Further, in the decking tile 60 the feet 20 within each quarter of the tile 60 are arranged on parallel lines, with the feet 30 forming concentric diamond shapes on the entire tile. That is, each quarter of the decking tile 60 can be derived by rotating any one of the other quarters about the centre of the tile. In contrast, the feet on the decking tile 10 of the first embodiment form diamonds within each quarter.

The four inner most portions 12 of the decking tile 60 each include a further cylinder 62 arranged to receive a fastener, such that each of the four inner most portions 12 can receive three fasteners. The further cylinders 62 are provided on one of the reinforcing members 16 and are located adjacent the centre of the tile Further, the decking tile 60 further includes additional feet 64 as shown in Figure 3. The additional feet 64 act to further distribute weight placed on the decking tile 60. Where one of the additional feet 64 is provided at a sub-division of a portion 12, the foot 64 is itself sub-divided into two halves so as to still permit removal of one of the sub-portions 32.

Figure 2 is an upper perspective view of the decking tile 60 looking onto the upper surface 30. Figure 7 is a top plan view the decking tile 60 looking onto the upper surface Figure 3 is a lower perspective view looking toward the lower surface 64.

WO 99/36638 PCT/AU99/00027 -11 Figure 4 is an upper perspective view of part of two adjacent tiles 60 showing the first and second components connected.

As stated in relation to the first embodiment, each portion 12 or sub-portion 32 can be removed from the tile by severing the membranes 14 and/or further membranes 34. Figures 5 and 6 shows the decking tile 60 with a quarter of the decking tile removed by severing the further membranes 34.

Figures 8 to 18 shows some of the arrangements of wooden slats which are possible with the decking tiles of the invention. Each of figures 6 to 12 has the apertures 28 of the decking tile 60 shown in broken lines.

Figure 8 shows the typical arrangement for decking tiles, with four wooden slats layed in a parallel manner. It is envisaged that where the slats are arranged in the configuration shown in figure 8, only one fastener in each portion 12 of the decking tile 10 is necessary to ensure a secure fixture of each slat to the decking tile. If any of the portions 12 of the decking tile need to be removed, further fasteners can then be provided in the other apertures 28 to ensure the remaining slat is secured to the decking tile without being able to rotate.

Figure 9 shows an arrangement of the wooden slats, with the middle two slats being cut so as to form a diamond (from two triangles) in the middle of the tile.

Because the cuts of the middle two slats fall over the apertures 28 in the inner most four tiles, the further cylinders 62 provide a mechanism for securing the inner most triangles of the wooden slats to the tile. It is specifically for this pattern that the further cylinders 62 are provided on the decking tile 60. If it was not desired to produce this pattern, the further cylinders 62 would not be necessary.

Figures 10 to 18 show further patterns of wooden slats that can be accommodated on the decking tiles of the second embodiment. Most of these patterns can also be accommodated on the decking tile of the first embodiment.

WO 99/36638 PCT/AU99/00027 -12- Figure 14 shows a further arrangement of the wooden slats, with the middle two wooden slats being replaced with two trapezoid-shaped slats and with triangleshaped slats at each end. Whilst the further cylinders 62 are not required to retain the slats in this pattern, it is to be noted that this pattern requires the apertures 28 to be provided in the configuration shown in relation to the decking tile 60, since the apertures 28 on the decking tile 10 would fall in the gap between the triangle shaped slats and the trapezoid-shaped slats. It is for this reason that the arrangement of the apertures 28 and feet 20 shown in relation to the decking tile 60 is the preferred arrangement.

Accordingly, it can be seen that the invention provides a decking tile which alleviates one of the problems with existing decking tiles, in that portions of the decking tile can be removed and the slats can still be retained without rotation.

In addition, the invention provides a decking tile which is capable of having slats form various patterns, greatly enhancing the aesthetic appearance of the decking tiles. Such patterns are not possible with existing decking tiles.

It should be appreciated that the scope of this invention is not limited to the particular embodiments described above.
