FIG. 1 shows decking planks 40 partially laid onto the support structure for provision of a decking surface above the original surface 20. Each pedestal may be adapted to be of a height which, when arranged with other pedestals on a surface, ensures that the decking is flat over the entire surface, and, where the original surface is uneven, this can be achieved by for example individual pedestals being ‘jacked’ to different heights.

[0049] FIG. 2A shows a perspective view of a decking support element 1 each end of which, as shown in FIG. 2B, has a generally square cross section, the decking support element suitable for use as part of a support structure for decking in accordance with the present invention. A plurality of such decking support elements may be laid on pedestals in the manner shown in FIG. 1. Conventionally such support structure components are provided in fixed lengths which are placed end to end or cut to size to suit. The same is contemplated in the present invention.

[0050] FIG. 2B shows an end view of the decking support element 1 of FIG. 2A.

[0051] As can be seen in FIGS. 2A and 2B, the decking support element includes side walls 50, 70 extending substantially parallel to each other, and upper 90 and lower 110 walls also extending substantially parallel to each other, the longitudinal length of the respective walls defining the length of the element. Feet 130 are positioned at the end of each side wall 50, 70 at the base of the element, extending substantially parallel to the upper and lower walls 90, 110, and orthogonally to side walls 50, 70. An inner portion 150 of each sidewall foot 130 extends inwardly towards the inner portion 150 of the foot of the other sidewall. An outer portion 170 of each foot 130 extends outwardly and away from the respective sidewall 50, 70 and ends in a lip 180 to provide a trough 190 adjacent to and at the base of the sidewall 50, 70.

[0052] At a top of each sidewall 50, 70 adjacent the upper wall 90 there is provided a respective exterior trough 200, the upper wall 90 further including a pair of rails 210, each one of the pair adjacent a respective exterior trough 200 and set above the upper wall 90 on respective supports 212. The rails are adapted to each receive a plastics strip (not shown), an upper surface of each of which sits proud of the supports 212.

[0053] FIGS. 2A and 2B also show a support strut or shelf 220, on an interior surface of each sidewall 50, 70.

[0054] It is contemplated that each decking support element may be placed on a, or on a series of, pedestals 10, arranged on a surface for example the surface 20 of FIG. 1, to be covered with planks of decking 40, or other suitable surface.

[0055] FIG. 3A shows a perspective view of a decking support element 500 with a taller cross section than in the arrangement of FIGS. 2A and 2B, the taller decking support element suitable for use as part of a support structure for decking in accordance with a further embodiment of the present invention.

[0056] FIG. 3B shows an end view of the taller decking support element 500 of FIG. 3A. It is contemplated that the taller decking support element 500 may also be placed on a, or on a series of, pedestals 10, arranged on a surface for example the surface of FIG. 1 to be covered with planks of decking 40, or other suitable surface.

[0057] The taller decking support element of FIGS. 3A and 3B includes sidewalls 550, 570, upper 590 and lower 610 walls, and feet 630, however while each foot includes a portion which extends inwardly towards the other foot there is no additional portion that extends outwardly and away from the sidewall with a lip, as is present in FIGS. 2A and 2B.

[0058] Each sidewall 590, 610 of the taller decking support element of FIGS. 3A and 3B includes a trough 690 on an exterior surface, extending along the length of the wall, and equivalent to the trough 190 of FIGS. 2A and 2B but positioned approximately mid-way between the top and bottom of the sidewall, between the upper 590 and lower 610 walls. The top portion of the taller decking support element of FIGS. 3A and 3B is structured in the same manner as the top of the decking support element of FIGS. 2A and 2B.

[0059] FIGS. 3A and 3B therefore show a decking support element which is generally of a greater height than the decking support element of FIGS. 2A and 2B, and which provides for a more flexible height gradation than other systems.

[0060] FIGS. 4A-E show various views of a connection element in accordance with an embodiment of the present invention.

[0061] FIG. 4A shows a front view of the connection element 700, with in this case a design 701 positioned on a surface thereof although this is entirely optional. An upper part of the element is divided into three portions, two edge portions 710, and a mid-portion 720 intermediate said edge portions and separated therefrom by a gap 730.

[0062] FIG. 4B shows a rear view of the connection element 700 of FIG. 4A, with a rear view of the two edge portions 710 and the mid-portion 720, separated by the gap 730. FIG. 4B also shows structures 740 present on the rear surface of the connection element which are shown more fully in FIGS. 4C-E.

[0063] FIG. 4C shows a side view of the connection element 700 of FIGS. 4A and 4B showing the arrangement of the lower portion of the element, in particular showing that the base of the element includes a lip 750 comprising a shelf that first extends away from the substantially planar surface of the element and which then turns downward to extend away from the base portion in a direction broadly parallel to the substantially planar surface of the element. FIG. 4C also shows detail of the structures 740 present on the rear surface of the element, extending away from the element and which will be discussed in more detail in relation to FIGS. 4D and 4E.

[0064] FIGS. 4D and 4E show perspective views of the connection element 700 of FIGS. 4A-C from the front and rear respectively. In particular FIG. 4D shows lip 750 at the base of the element; two edge portions 710 and mid-portion 720 on an upper part of the element, and structures 740 present on, and extending away from, the rear surface of the element with a groove 760 present along respective outer side surfaces of structures 740.

[0065] FIG. 4E shows in detail structures 740 extending away from the rear surface of the element 700, with the channel 760 positioned therein. As can be seen structures 740 substantially comprise top, base and side walls enclosing open space to provide strength and rigidity while minimising the weight of the element.

[0066] As can be seen from FIG. 4E structures 740 are adapted to fit conveniently into open ends of decking support elements, the walls in particular adapted to fit snugly within and against the interior walls of the decking support elements. In accordance with an embodiment shelf 220 provided on an interior surface of a decking support element may be accommodated within a groove 760 which may be provided on a wall of structure 740.

[0067] FIG. 4E also shows detail of the edge portions 710 and mid-portion 720 separated by gap 730. As can be seen, the edge and mid-portions include a ridge 725 on an upper surface, generally on the same side of the connection element as that of the lip 750, the ridge 725 defining a channel 726. The mid-portion 720 is separated from the edge portions 710 by a gap and is resiliently deformable out of the plane of the connection element. The mid-portion also includes further surface features 735 which provide some traction on the mid-portion to for example assist with the deformation. As can be seen from FIGS. 4D and 4E these features 735 form a stepped surface.

[0068] In use, where it is desired to provide decking on a surface area, for example around a building or on a balcony or other surface, a series of pillars may conventionally be provided to generate a broadly planar surface on which the decking may ultimately be placed. A series of first generally elongate decking support elements 1 in accordance with the present invention may then be placed on the pillars in a uniform, and generally conventional, manner.

[0069] The decking support elements may be placed on the pillars, or other support, on feet 130, 630 at a base of the decking support element.

[0070] In accordance with the present invention a next step provides for the first decking support elements 1 to be linked with further decking support elements 1 to provide a secure and stable arrangement upon which decking may be placed.

[0071] In order to link a first decking support element 1 with a further decking support element 1 a connection element 700 is first coupled to the first decking support element 1, and this occurs in two stages. In a first stage a lip 750 at a base of the connection element 700 is placed in a trough 190 that runs along the base of one of sides 50, 70 of the decking support element 1. In a second stage a top of the connection element 700 is urged towards the top of the decking support element such that ridge 725 positioned at a top of the connection element and curving over to overhang a side of the connection element to provide a channel 726 is urged towards a trough 200 that runs along the upper side wall 50, 70 of the decking support element 1.

[0072] The top of the connection element 700 is divided into three portions: a mid-portion 720 intermediate two edge portions 710 and separated therefrom by a gap 730. Mid-portion 720 is resiliently deformable from the plane of the connection element and can deflect away from the plane of the connection element when subjected to a force. When the top of the connection element is urged towards a top of the decking support element ridge 725 abuts an edge of trough 200 and on being further urged towards the top of the decking support element is subject to a force deflecting it out of the plane of the connection element. The mid-portion flexes away from a rest position and eventually slips over the edge of the trough 200 so that the mid-portion snaps back into its rest position, with channel 726 accommodating, and securely held by, an edge of trough 200.

[0073] The edge portions also include channels which accommodate the edge of the trough.

[0074] The connection element is thereby held securely against a side of the decking support element, with a first side engaged with the decking support element and a second side, with second engagement means, exposed.

[0075] A further decking support element may then be attached to the exposed second side of the connection element to couple the two decking support elements together. An open end of the further decking support element is urged towards the exposed second side of the connection element such that the further features 740 enter into the open end, the internal walls of the decking support element accommodating the walls of the further feature, and where present, each shelf 220 entering into respective grooves 760 to secure engagement of the decking support element with the connection element and engagement of the two decking support structures together.

[0076] This process can be repeated for other decking support structures and connection structures until all the required decking support structures are engaged together in the desired orientation. It is contemplated that a first decking support structure will be orthogonally coupled to a further decking support structure by a said connection element.

[0077] For decking support elements of a second height, taller than the first height, the connection element engages with a first trough 690 which is positioned intermediate the upper and lower portions of the sidewalls 50, 70, however the further process is the same.

[0078] It is contemplated that the decking support structures will be formed from Aluminium or other suitable substance, and the connection structures will be formed from a plastics material.

[0079] The invention is not restricted to the details of the foregoing embodiments. For example sidewalls 50, 70, 550, 570 of the decking support elements may be curved or otherwise oriented, the lip 750 on the connection element may include a different shape, the essential feature being that it provides for a feature that may be inserted into a trough and engage with the edges thereof. The lip may be considered to provide a hooking means. The scope of the invention is contemplated to include any one of a variety of means to secure this functionality. In addition, shelf 220 is provided to secure a second side of a connection element within an open end of a decking support element by means of groove 760, however it may be that the walls of structure 740 will, when engaged within walls 50, 70, 550, 570 provide a sufficient engagement. Shelf 220 is provided in part to strengthen the structure of decking support element while minimising the weight of the element and minimising the quantity of material needed for its manufacture. In addition, the features 735 on the surface of the mid-portion 720 can be other features than a stepped surface, any surface feature that provides traction is contemplated to fall within the scope of the invention. While the decking support element is contemplated to be placed on pillars it is contemplated that the arrangement of the present invention is adaptable to be used on different surfaces, for example a conventional surface or on alternative means to provide a planar surface. The pair of rails 210 positioned on a top of said decking support structures may include more or fewer rails, and may be positioned, or shaped, differently. The functionality of the plastics strip provided to the rails may also be accomplished by other means, which are contemplated to fall within the scope of the present invention. The feet of the taller decking support structure may include a portion that extends outwardly and away from the sidewall 550, 570.
