Description

MODULAR SUPPORT FRAME KIT FOR AN OUTDOOR DECKING STRUCTURE

FIELD OF THE INVENTION

Embodiments of the present invention relate to a modular support frame kit for an outdoor decking structure. In particular, but not exclusively the modular support frame kit and the outdoor decking structure are configured for use with static caravans, lodges or park homes.

BACKGROUND TO THE INVENTION

A caravan is typically a prefabricated accommodation structure that is transportable onto a site either by being towed on its own wheels or transported on a trailer by another vehicle. The site may be a caravan park. A static caravan is a caravan that is left permanently or semi-permanently in one place, so its owners may wish to construct improvements around the exterior of the caravan.

A park home has the above functions but is typically designed to a higher standard and may be lived in all year round. In the United Kingdom, static caravans and park homes are described in different standards EN1647 and BS3632 respectively, with the latter being more stringent on features such as insulation. A park home is mobile and is also referred to as a mobile home because it is designed to be relocated in one piece or in a few pieces, either on its own wheels or by being towed or transported on a trailer by another vehicle.

A lodge is typically functionally similar to a park home but may have a different exterior style.

In the following description, the term 'prefabricated accommodation' will be used to generally refer to the above structure types and their equivalents.

It is common for prefabricated accommodation to comprise an external door that is elevated above ground level by a greater distance than a typical constructed-on-site permanent residence. The base of the doorway may be approximately 700mm above ground level, give or take 100mm. Therefore, some owners of static caravans will seek to construct an outdoor decking structure having a deck level close to the base of the doorway, so that they can leave the prefabricated accommodation without a significant step down.

Typically, owners are motivated to install the outdoor decking structure in such a way that it functions as an outdoor living space. The outdoor decking structure may have a large plan area to provide space for seating, cooking or dining. For example, the outdoor decking structure may wrap around more than one exterior face of the static caravan. The term veranda is also generally used to describe such structures for prefabricated accommodation, whether or not they have a roof.

An outdoor decking structure may comprise a timber deck or a tiled/paved deck or equivalent. A balustrade or equivalent may at least partially enclose the deck for safety or aesthetics.

A prior outdoor decking structure is of a timber post and beam architecture. Timber posts are sunk into the ground or secured to ground-penetrating concrete footings. The timber posts support timber beams. The timber beams support the deck.

A skilled installer or team of installers is required to construct outdoor decking structures, resulting in high costs and long installation times. In addition, hardwood for outdoor decking structures often comes from tropical forests.

DETAILED DESCRIPTION OF VARIOUS EMBODIMENTS OF THE INVENTION

FIG. 1 schematically illustrates a side view of an example outdoor decking structure 1. The outdoor decking structure 1 comprises a deck 3 supported by a modular support frame kit 2 The deck 3 may comprise a timber deck or a tiled deck, or any other appropriate deck. The modular support frame kit 2 may be compatible with different types 10 of deck The modular support frame kit 2 comprises a first frame A. As can be seen in FIG. 2, the first frame A comprises a plurality of frame members FM. The modular support frame kit 2 further comprises a second frame B. As can be seen in FIG. 2, the second frame B also comprises a plurality of frame members FM. FIG. 2 onwards show additional optional frames C, D. The frame members may be beams.

As shown in FIG. 1, each frame A, B has a shape defining a substantially planar deck substructure onto which the deck 3 can be laid. Laying the deck 3 can comprise, for example, drilling self-drilling fasteners through the deck 3 into the frame. The plan view shape of the deck substructure is not visible in the side view of FIG. 1 but is visible in the perspective views and plan views of the later FIGS. An individual deck member (e.g., plank of wood) may be longer than each frame and can be laid over a plurality of frames, with or without an intervening substrate.

In at least some examples, the frame members FM are metallic for strength and durability. For example, the frame members FM may comprise steel, aluminium, or equivalent materials. The frame members FM may comprise metal profiles. The metal profiles can comprise hollow section tubes such as square tubes or circular tubes. Additionally, or alternatively, at least some metal profiles can comprise plate sections. In some examples, a wall-thickness of the hollow section tubes is less than 3mm so that self-drilling screws can be used to fasten the deck 3 to the hollow-section tubes.

The frame members FM are pre-assembled into shapes such as quadrilateral shapes Pre-assembly refers to the frames being assembled prior to delivery to the end user. This is convenient and means that the end user does not necessarily need to be a trained professional.

In some, but not necessarily all examples the frame members FM of each frame are pre-assembled using permanent, non-reversible connections so that the pre-assembled frame members FM are not detachable from each other without destructive effects. For example, the frame members FM may be pre-assembled using welding. The permanent connections ensure that the frames are strong.

The frames are not secured to one another until received by the end user. This minimises packaging space during transportation and makes manoeuvring of frames easier. The frames each comprise securing means (securing portions) such as fastener holes, plugs/sockets, slots, or a combination thereof, configured to enable the end user to secure the frames to one another. In at least some examples, fastener holes are bolt holes and the kit 2 comprises bolt fasteners or similar.

In some, but not necessarily all examples, each deck substructure is elevated above the ground surface to a height Zi having a value between approximately 500mm and approximately 800mm, onto which the deck 3 can be laid. The thickness of the deck 3 depends on the implementation but can be between 50mm and 150mm, for example. The deck level height Z2 is the sum of these two heights, and is coplanar with or slightly below a height of a door of the prefabricated accommodation (not shown).

In an implementation, the deck level height Z2 is a value within 50mm of 700mm and the deck substructure height Li is a value within 50mm of 600mm. In some examples, the deck substructure height is user-adjustable by a range having a value of at least approximately 40mm, and/or the deck substructure height is independently adjustable at different parts of each frame to compensate for sloping or uneven ground to provide a horizontal plane. In some examples, the range of adjustability is no more than 300mm.

The modular support frame kit 2 is provided with a plurality of legs L configured to elevate the deck substructure above a ground surface. The legs L may be configured to enable the adjustment, as discussed later. In at least some examples, the legs L are not pre-assembled frame members and are instead configured to be user-securable to the frames by the end user. This ensures that the frames can be flat-packed for transportation in stacks. In other embodiments, the legs L may be pre-assembled frame members.

In some, but not necessarily all examples, the illustrated legs L are configured to rest on a ground surface, rather than penetrate the ground surface. In the illustrated examples, but not necessarily all examples, the legs comprise foot pads FP (ground pads) configured to spread weight loads across a larger surface area (e.g., >double) than an average cross-section of the legs L. The foot pads FP may point inwardly to not extend beyond a plan view periphery of the deck substructure. In some examples, a foot pad FP can comprise an opening configured to receive a nail or peg or other fastener so that a leg L resting on the ground surface can be fastened to the ground.

The ground surface may be at least partially prepared in advance but does not have to be precisely level. For example, the ground surface may comprise a concrete base or paved area. The adjustability of the legs L can accommodate discrepancies in the ground level.

FIG. 2 schematically illustrates a perspective view of a further example modular support frame kit 2. The modular support frame kit 2 of FIG. 2 may comprise any of the features of the modular support frame kit 2 of FIG. 1, and additional features are shown. Most notably, the modular support frame kit 2 of FIG. 2, but not necessarily all embodiments thereof, comprises multiple different types of frames that are configured to interconnect in a grid pattern.

Different 'types' of frame are differentiated herein based on one or more of the following differences: different numbers of legs L; different numbers/types of peripheral frame members; and/or different arrangements of securing means.

There are advantages to using different types of frames configured to interconnect in a particular way. For example, some types of frames can depend on neighbouring frames to which they are connected. At least some frame types may distribute loads between each other. This enables material to be removed from at least some of the frame types. For example, redundant legs L can be deleted wherever a leg L for one frame can be shared by multiple frames. Some frame members FM can be deleted or reduced in linear mass density (e.g., reduced cross-section) if said frame member FM shares a common edge with a frame member FM of a neighbouring interconnected frame.

FIG. 2 illustrates four different types of frames. Frame A is a first frame type (first frame'). Frame B is a second frame type (second frame'). Frame C is a third frame type (third frame'). Frame D is a fourth frame type (fourth frame').

Depending on implementation, more or fewer types of frames can be provided.

In some, but not necessarily all examples, the illustrated first frame A is configured as a starter frame that is configured to stand upright without requiring support by any other frame. For example, legs L can be pre-assembled or securable by an end user to each corner of the first frame A. In order to assemble the frames, the first frame A is initially positioned as a starter frame. The first frame A is positioned at an intended exterior corner location of the outdoor decking structure.

The second, third and fourth frames B, C, D may each be configured as 'reduced material' frames that comprise less material than the first frame A, and as such are lighter and require less material to manufacture. The illustrated second, third and fourth frames B, C, D are each configured to require support by another interconnected frame in order to stand upright and/or in order to withstand nominal service loads.

In the arrangement shown in FIG. 2, the second frame B is configured to connect to the first frame A. The third frame C is configured to connect to a different side of the first frame A than the second frame B is connectable to. The fourth frame D is configured to connect to both the second frame B and the third frame C. The fourth frame D is diagonally offset from the first frame A. In some, but not necessarily all examples, the outdoor decking structure can be further extended in an illustrated first direction D-1, in which case the illustrated second frame B may comprise securing means for securing to another second frame B. A further one of the second frame B (not shown) is configured to connect to the second frame B so that second frames B are configured to interconnect in series in the first direction D1 away from the first frame A. The second frames B may be configured to extend along a first perimeter edge of the outdoor decking structure. A series of frames along the first perimeter edge starts with a first frame A (corner frame), comprises one or more second frames, and may end at a second frame B at the other corner.

In some, but not necessarily all examples, the outdoor decking structure can be further extended in an illustrated second direction D2, wherein a further one of the third frame C (not shown) is configured to connect to the third frame C so that third frames C are configured to interconnect in series in the second direction D2. The illustrated second direction D2 is orthogonal to the first direction D-1. The third frames C may be configured to extend along a second perimeter edge of the outdoor decking structure. A series of frames along the second perimeter edge starts with the first frame A (corner frame), comprises one or more third frames C, and may end at a third frame C. If the outdoor decking structure is extended as described above, additional ones of the fourth frames D can be provided. Each fourth frame D is connected, directly or indirectly via other fourth frames D, to a pair of perimeter frames, one being a second frame B at the first perimeter edge and the other being a third frame C at the second perimeter edge.

Therefore, a row of frames extending in the first direction D-1 and containing a fourth frame D starts with a third frame C of the second perimeter edge and comprises a series of fourth frames D (including the above) dependent on the third frame C. In some, but not necessarily all examples, every other frame in the row may be a fourth frame D, up to and including the frame at an opposite perimeter edge.

A column of frames extending in the second direction D2 and containing the same fourth frame D starts with a second frame B of the first perimeter edge and comprises a series of fourth frames D (including the above) dependent on the second frame B. In some, but not necessarily all examples, every other frame in the column may be a fourth frame D, up to and including the frame at an opposite perimeter edge.

Each row of frames depends on a third frame C for support and each column of frames depends on a second frame B for support, as the fourth frames D may be unable to stand stably upright unless they are part of a column and a row comprising a second frame B and a third frame C respectively.

In FIG. 2, but not necessarily all examples, the frames each comprise four sides and are configured to interconnect in a regular grid pattern in plan view.

Specifically, the illustrated frames interconnect in a substantially rectilinear grid pattern or a Cartesian (square) grid pattern. The illustrated first direction D1 and second direction D2 are orthogonal to each other.

In other examples, the regular grid pattern can comprise a skewed grid pattern or a curvilinear grid. In further examples, the frames comprise three sides or more than four sides, changing the grid pattern accordingly.

It would be understood that the modular support frame kit 2 could be further supplied with additional frames that are non-rectilinear in plan view, to give the end user more freedom over the shape of the perimeter of their outdoor decking structure. See for example FIG. 9 in which a fifth frame type E is illustrated.

The frames can be straight-sided as shown, or can comprise one or more 15 curved-sides.

Some of the frames B, D can comprise a balustrade support BS configured to receive and support a balustrade (not shown). The balustrade support BS is described in more detail later.

FIG. 3 illustrates an example first frame A in more detail, including a plan view, a side elevation, and an end elevation. FIG. 4 illustrates an example second frame B in more detail, including a plan view, a side elevation, and an end elevation. FIG. 5 illustrates an example third frame C in more detail, including a plan view, a side elevation, and an end elevation. FIG. 6 illustrates an example fourth frame D in more detail, including a plan view, a side elevation, and an end elevation.

Common features of the frames A-D of FIGS. 3-6 are described below.

The first frame A of FIG. 3 comprises a first side Si, a second side S2, a third side S3 opposite and parallel to the first side Si, and a fourth side S4 opposite and parallel to the second side S2. Sides Si and S3 may be perpendicular to sides S2 and 54. In the illustrations, but not necessarily in all examples, the first frame A defines a quadrilateral deck substructure area in plan view and comprises no further sides.

The second frame B of FIG. 4 also comprises a first side S1, a second side S2, a third side S3 opposite and parallel to the first side Si, and a fourth side S4 opposite and parallel to the second side S2. Sides Si and S3 may be perpendicular to sides S2 and S4. In some, but not necessarily all examples, the second frame B has substantially the same deck substructure plan view area as the first frame A. In some, but not necessarily all examples the second frame B also defines a quadrilateral deck substructure area.

The third frame C of FIG. 5 also comprises a first side Si a second side 52, a third side S3 opposite and parallel to the first side Si, and a fourth side S4 opposite and parallel to the second side S2. Sides Si and S3 may be perpendicular to sides S2 and S4. In some, but not necessarily all examples, the third frame C has substantially the same deck substructure plan view area as the first frame A and the second frame B. In some, but not necessarily all examples the third frame C also defines a quadrilateral deck substructure area.

The fourth frame D of FIG. 6 also comprises a first side Si, a second side S2, a third side S3 opposite and parallel to the first side Si, and a fourth side S4 opposite and parallel to the second side S2. Sides Si and S3 may be perpendicular to sides S2 and S4. In some, but not necessarily all examples, the fourth frame D has substantially the same deck substructure plan view area as the first frame A, the second frame B and the third frame C. In some, but not necessarily all examples the fourth frame D also defines a quadrilateral deck substructure area.

Example dimensions and weights are provided. Optionally, the dimensions and weights can be optimised for hand-manoeuvring and assembly by a single person. The longest plan view dimension X of the or each frame A, B, C, D can be less than two metres (excluding securing means). Optionally, in the illustrated examples, the longest dimension X is along sides S2 and S4 (from side Si to side S3). The shorter dimension Y is along sides Si and S3 (from side S2 to side 54). The mass of each frame (excluding legs L) can be less than 30 kilograms.

Each frame comprises a plurality of peripheral frame members PFM. A peripheral frame member PFM refers to a frame member (beam) at a periphery of the frame, defining an outer edge of a given side of the frame.

In one implementation, a length of metal profile (e.g., hollow section) is bent (e.g., at miter cuts) to create one or more corners, so that the same length of metal profile defines more than one of the peripheral frame members PFM of a given frame. In other implementations, separate lengths of metal profiles are joined together at corners (e.g., butt joints, mitered butt joints), each metal profile being a separate peripheral frame member.

The peripheral frame members PFM enclose a substantially planar hollow interior area in plan view, acting as the area of the deck substructure. The peripheral frame members PFM can be regarded as beams.

In some, but not necessarily all examples, the frame members further comprise one or more internal beams IB in the interior area rather than at the periphery.

In some examples, the internal beams IB are pre-assembled to the peripheral frame members PFM. An internal beam IB is a beam that forms part of the deck substructure and demarcates the interior area into smaller areas/cells, providing mid-span support along the dimension X (or Y). In the illustrated examples, an internal beam IB spans between-and is supported by at least a pair of peripheral frame members PFM so that load applied to the internal beam IB is transferrable to ground via the pair of the peripheral frame members PFM.

In FIGS. 3-6, but not necessarily all examples, each frame comprises more than one internal beam IB. In FIGS. 3-6, but not necessarily all examples, each frame comprises the same number of internal beams IB. In FIGS. 3-6, but not necessarily all examples, a first internal beam IB extends between sides S2 and 54 of a given frame, and a second internal beam IB also extends between the same sides S2 and S4. This is because the peripheral frame members PFM along sides S2 and 54 have longer spans than the peripheral frame members PFM along sides Si and S3.

In another example, one or more of the internal beams IB extends between sides Si and S3.

The securing means for connecting frames to each other are now described, with reference to FIGS. 3-6 and 8. The securing means on sides S2 and/or S4 of a frame for connecting to another frame may be a different securing means than that on sides Si and/or S3 of the same frame. This ensures that frames can only be connected to predetermined sides of other frame types.

FIG. 8 (detail view) illustrates an example of a first securing means. The first securing means is at a corner of the frame and can be for connecting frames in the first direction Di. Alternatively, the first securing means can be for connecting frames in the second direction Di. The first securing means comprises a plug-socket arrangement.

One of the sides Si or S3 comprises a plug p, and the other of the sides S3 or Si comprises a socket s. This creates an interference that helps to transfer loads and cause the connected support frames to behave as an integral structure. The plug-socket connection may be sufficiently tight and secure that it behaves as a fixed connection rather than a pin connection, so that bending moment loads applied to one frame can be resisted by neighbouring frames.

In the example of FIG. 8, a peripheral frame member PFM is a hollow section and its interior hollow space functions as a socket s. The plug p comprises a sleeve shaped to slide into the socket. The sleeve may have a tight fit with the socket. In some examples, the plug p and socket s are separately securable once engaged with each other, to prevent sliding out. For example, a fastener hole (not shown) in the plug p may align with a fastener hole in the socket s (not shown) when correctly engaged, so that a fastener (not shown) can be inserted therethrough to secure the plug p in the socket s.

An overall effect of the illustrated plug-socket arrangement is that some peripheral frame members PFM can be spliced end to end to connect the frames to each other. The spliced peripheral frame members PFM may be coaxial with each other.

FIGS. 3-6 illustrate an example of a second securing means for connecting frames to each other in the second direction D2. In the illustrated arrangement, the second securing means comprises a plurality of fastener holes FH. The fastener holes FH are predrilled into a peripheral frame member PFM. The fastener hole spacing may be configured so that the fastener holes FH on a side (e.g., side S4) of one frame are alignable with the fastener holes FH on the peripheral frame member PFM of the corresponding side (e.g., side S2) of the other frame. Fasteners can then secure the peripheral frame members PFM together.

The illustrated second securing means does not use a plug-socket arrangement, to avoid a situation in which protruding plugs for directions D-1 and D2 protrude in different directions and therefore interfere with the fitting of each other. Therefore, the use of two different securing means, one of which comprises a plug-socket arrangement for a given direction, provides an optimal balance between strength and ease of assembly. An alternative approach is to use a single non-interfering securing means such as fasteners and fastener holes, for frame interconnections in both directions D1 and D2.

FIGS. 3-7 show each frame comprising one or more leg portions LP. The term 'leg portion' generically refers to either a pre-assembled (e.g., pre-welded) leg L or to a leg receiver configured to receive a user-securable leg L. In the illustrated examples, best illustrated in the detail view of FIG. 7, the leg portions LP are leg receivers. The illustrated leg receivers comprise leg sockets into which legs L can be inserted and secured by the end user. In some examples, a leg socket can comprise a hollow section similar to the geometry/shape used for the peripheral frame members PFM. The leg receivers LP may be pre-assembled (e.g., pre-welded) to an underside of each frame and may form a short frame member of the frame.

As shown in FIG. 7, a plurality of fasteners F to different sides of the leg L may secure the connection between the leg L and the leg receiver LP, for instance in a non-interference manner comprising tightening the fasteners F to exert pressure on the surface of the leg L. By applying fasteners F at two different sides of the leg L, the leg L is biased against a corner of the leg receiver LP to maximise friction against vertical sliding. This approach enables fine tuning of leg height. Alternatively, the connection may be secured using interference such as pushing fasteners F through aligned holes in the leg receiver LP and in the leg L. In the elevation views of FIGS. 3-6, the frames are shown with the legs [attached.

Features specific to the first frame A of FIG. 3 are described below.

The first frame A comprises enough legs L to stably stand upright without needing to be connected to another frame. In some examples, the first frame A comprises a total number of leg portions LP equal to its number of corners. In some examples, a leg portion LP is located at each different corner of the first frame A. The first frame A comprises peripheral frame members PFM at each of the sides Si, S2, S3, and S4. Optionally, each of the peripheral frame members PFM can be a hollow section.

The securing means of the first frame A is configured with at least the following compatibilities: - side 52 of the first frame A is configured to be secured to side 54 of a third frame C to extend frames in the second direction D2; - side S3 of the first frame A is configured to be secured to side Si of a second frame B to extend frames in the first direction Dl.

A 'compatibility' can comprise corresponding securing means, such as a socket corresponding to a plug, and/or corresponding fastener hole patterns. Additionally, or alternatively, a compatibility can depend on a pattern of leg portions LP.

In at least some examples, the securing means of the first frame A are configured so that at least some of the following incompatibilities arise: - side Si and/or S3 of the first frame A is not compatible with a third frame C when extending in the first direction D1; - side S2 and/or S4 of the first frame A is not compatible with a second frame B when extending in the second direction D2; - the first frame A is not compatible with a fourth frame D. An 'incompatibility' can comprise different securing means, such as a socket not corresponding to a plug, and/or different fastener hole patterns. Additionally, or alternatively, an incompatibility can depend on a pattern of leg portions LP.

In some examples, the other frames B, C can be provided in left-and right-handed configurations, and the first frame A may be further adapted so that: - side Si of a second frame B may be securable to side Si of the first frame A; and/or - side 52 of a third frame C may be securable to side 54 of the first frame A. Features specific to the second frame B of FIG. 4 are described below.

The securing means and/or leg portions LP of the second frame B are configured with at least some of the following compatibilities: - side Si of the second frame B is configured to be secured to side S3 of a first frame A to extend frames in the first direction Dl; - side Si of the second frame B is configured to be secured to side S3 of another second frame B to extend frames in the first direction D-1; - side S2 of the second frame B is configured to be secured to side S4 of a fourth frame D to extend frames in the second direction D2; - side 53 of the second frame B is configured to be secured to side Si of another second frame B to extend frames in the first direction W. In at least some examples, the securing means and/or leg portions LP of the second frame B are configured so that at least some of the following incompatibilities arise: - side Si and/or S3 of the second frame B is not compatible with a fourth frame D when extending frames in the first direction Di; - side S2 and/or S4 of the second frame B is not compatible with a first frame A when extending frames in the second direction D2; - side S2 and/or S4 of the second frame B is not compatible with another second frame B when extending frames in the second direction D2; -the second frame B is not compatible with a third frame C. In an implementation, the second frame B can rely on a plurality of plug/socket connections for making a complete connection to another frame. The second frame B can comprise a plurality of plugs at adjacent corners of a side and facing a common direction and/or can comprise a plurality of sockets at adjacent corners of an opposite common side and facing a common opposite direction.

The illustrated second frame B optionally comprises fewer leg portions LP than the first frame A. The second frame B may comprise fewer leg portions LP than there are corners of the second frame B. A leg portion LP is located at each of a subset of different corners of the second frame B. The illustrated second frame B comprises two leg portions LP. The leg portions LP of the second frame B are illustrated at the corners 52-53 and S3-S4 of the second frame B, distal from the first frame A. The second frame B does not comprise leg portions LP at the corners S4-S1 and Si-S2 proximal to the first frame A, because the leg portions LP of the first frame A or of another intervening second frame B are shared between the frames.

As a result, the second frame B can only stand stably upright when connected directly or indirectly to the first frame A. Common leg portions LP are shared between the frames A, B. The illustrated second frame B further optionally comprises fewer peripheral frame members PFM than the first frame A. The second frame B does not comprise a peripheral frame member PFM at its side Si, because a peripheral frame member PFM at side S3 of the first frame A (or of an intervening second frame B) is already present, so a wasteful 'doubling up' of peripheral frame members PFM is avoided.

The illustrated second frame B further comprises an optional balustrade support BS. The illustrated balustrade support BS comprises a block or plate slightly inboard of a peripheral frame member PFM. A balustrade can be secured to the block or plate via a fastener. The illustrated balustrade support BS is at the side 53 of the second frame B. Additionally, or alternatively, a balustrade support BS can be provided at one or more other sides of the second frame B. The illustrated second frame B further comprises an optional boundary beam BB extending close to (e.g., within 30cm) a peripheral frame member REM and extending parallel to the peripheral frame member PFM. This means that deck members do not need to extend all the way to the peripheral frame member PFM and instead their ends can be fastened to the boundary beam BB. A boundary deck member can be laid along the boundary of the second frame B, parallel to and between the peripheral frame member PFM and the boundary beam BB. The boundary deck member may extend between adjacent balustrade posts.

In some examples, a variant of the second frame B omits the balustrade support BS. In some examples, the second frames B with or without the balustrade support BS at side S3 may comprise securing means (e.g., plugs, sockets) for further extending the series of second frames B along the perimeter edge of the outdoor decking structure. The second frame B that comprises the balustrade support BS at side 53 may be configured to reside at a corner or perimeter edge of the outdoor decking structure, and any securing means (if provided) may take the form of a socket rather than a plug, because a plug would protrude beyond the envelope of the outdoor decking structure.

Features specific to the third frame C of FIG. 5 are described below.

The securing means and/or leg portions LP of the third frame C are configured with at least some of the following compatibilities: -side S2 of the third frame C is configured to be secured to side 54 of a third frame C to extend frames in the second direction D2; - side S3 of the third frame C is configured to be secured to side Si of a fourth frame D to extend frames in the first direction D-1; - side S4 of the third frame C is configured to be secured to side S2 of a first 30 frame A to extend frames in the second direction D2; - side S4 of the third frame C is configured to be secured to side S2 of another third frame C to extend frames in the second direction D2.

In at least some examples, the securing means and/or leg portions LP of the third frame C are configured so that at least some of the following incompatibilities arise: -side Si and/or S3 of the third frame C is not compatible with a first frame A when extending frames in the first direction; - side Si and/or S3 of the third frame C is not compatible with another third frame C when extending frames in the first direction; - side S2 and/or S4 of the third frame C is not compatible with a fourth frame D; 10 -the third frame C is not compatible with a second frame B when extending frames in the second direction D2.

The illustrated third frame C optionally comprises fewer leg portions LP than the first frame A. The third frame C may comprise fewer leg portions LP than there are corners of the third frame C. A leg portion LP is located at each of a subset of different corners of the third frame C. The illustrated third frame C comprises two leg portions LP. The leg portions LP of the third frame C are illustrated at the corners Si -S2 and S2-S3 of the third frame C, distal from the first frame A. The third frame C does not comprise leg portions LP at the corners S3-S4 and S4-S1 proximal to the first frame A, because the leg portions LP of the first frame A or of another intervening third frame C are shared between the frames.

As a result, the third frame C can only stand stably upright when connected directly or indirectly to the first frame A. Common leg portions LP are shared between the frames A, C. The illustrated third frame C further optionally comprises a different type of peripheral frame member PFM' at one (or more) of its sides. The peripheral frame member PFM' at side S4 of the third frame C optionally comprises a plate section ('plate'). Optionally, the peripheral frame members PFM at the other sides S1-S3 may comprise hollow sections.

The plate PFM' at side S4 of the third frame C can be fastened to the peripheral 5 frame member PFM at side S2 of the first frame A (or of an intervening third frame C). The plate PFM' has a lower linear mass density than the peripheral frame member PFM to which it is fastened. The plate PFM' relies upon its connection to the peripheral frame member PFM of the other frame for structural strength. Therefore, a wasteful 'doubling up' of strength is avoided. 10 The illustrated plate PFM' is a continuous plate extending along the whole side 54 from corner S3-S4 to corner S4-S1, comprising a plurality of fastener holes FH and interconnecting the internal beams IB of the third frame C. Alternatively, the plate PFM' may be discontinuous, such as a set of fastener hole flanges at the corners and/or at the ends of the internal beams IB.

Alternative geometries to a plate PFM' include smaller/thinner hollow sections or different profile shapes.

Features specific to the fourth frame D of FIG. 6 are described below.

The securing means and/or leg portions LP of the fourth frame D are configured with at least some of the following compatibilities: - side Si of the fourth frame D is configured to be secured to side S3 of a third frame C to extend frames in the first direction Dl; - side Si of the fourth frame D is configured to be secured to side S3 of another fourth frame D to extend frames in the first direction Dl; - side S2 of the fourth frame D is configured to be secured to side S4 of another fourth frame D to extend frames in the second direction D2; -side S3 of the fourth frame D is configured to be secured to side Si of another fourth frame D to extend frames in the first direction D1; - side S4 of the fourth frame D is configured to be secured to side S2 of a second frame B to extend frames in the second direction D2; - side S4 of the fourth frame D is configured to be secured to side S2 of another fourth frame D to extend frames in the second direction D2.

In at least some examples, the securing means and/or leg portions LP of the fourth frame D are configured so that at least some of the following incompatibilities arise: - side Si and/or S3 of the fourth frame D is not compatible with a second frame B when extending frames in the first direction; - side S2 and/or 34 of the third frame C is not compatible with a third frame C when extending frames in the second direction D2; - the fourth frame D is not compatible with a first frame A. In an implementation, the second frame B can rely on a single plug/socket connection for making a complete connection to another frame. The second frame B can comprise a single plug and/or a single socket. Unlike the second frame B, more than one plug/socket connection is not required because the fourth frame D is supported from at least two non-opposing sides (by frames B and C).

The illustrated fourth frame D optionally comprises fewer leg portions LP than the second and third frames B, C. The fourth frame D may comprise only one leg portion LP as illustrated. The leg portion LP of the fourth frame D is illustrated at the corner S2-S3 of the fourth frame D, distal from sides S4 and Si and distal from the second and third frames B, C to which the fourth frame D is directly or indirectly connected.

The illustrated fourth frame D does not comprise leg portions LP at the corners 30 S4-Si, S1-52 or S3-S4 because the leg portions LP of the second and third frames B, C are shared at those corners.

As a result, the fourth frame D can only stand stably upright when connected directly or indirectly to both a second frame B and a third frame C. Common leg portions LP are shared between the frames A, B, C, D. The illustrated fourth frame D further optionally comprises fewer peripheral frame members PFM than the first frame A. The second frame B does not comprise a peripheral frame member PFM at its side Si, because a peripheral frame member PFM at side S3 of the third frame C (or of an intervening fourth frame D) is already present, so a wasteful 'doubling up' of peripheral frame members PFM is avoided.

The illustrated fourth frame D further optionally comprises a different type of peripheral frame member PFM' at one (or more) of its sides. The peripheral frame member PFM' may be at side S4 of the fourth frame D and may be similar to that described for the third frame C (e.g., plate or other). Optionally, the peripheral frame members REM at the other sides S2-S3 of the fourth frame D may comprise hollow sections.

The plate PFM' at side S4 of the fourth frame D can be fastened to the 20 peripheral frame member PFM at side S2 of the second frame B (or of an intervening fourth frame D). A wasteful 'doubling up' of strength is avoided.

The illustrated plate PFM' at side S4 of the fourth frame D can optionally be shorter than the opposite peripheral frame member PFM at opposite side 52 of the fourth frame D to further reduce material usage, because there may be no peripheral frame member PFM at side Si and no plug/socket connection at the corner S4-S1. Therefore, there may be no reason to extend the plate PFM' to the corner S4-S1. The plate PFM' of the fourth frame D may only be long enough to interconnect the internal beams IB and corner S3-S4 of the fourth frame D. The plate PFM' may be continuous or discontinuous.

The illustrated fourth frame D further comprises an optional balustrade support BS. The illustrated balustrade support BS is at the side S3 of the fourth frame D. Additionally, or alternatively, a balustrade support BS can be provided at one or more other sides of the fourth frame D. The balustrade support BS may be similar in design to that of the illustrated second frame B. The balustrade supports BS may be configured so that a balustrade can extend in a straight line (or other predetermined line) along a column/row of a plurality of frames.

In some examples, a variant of the fourth frame D omits the balustrade support BS. In some examples, the fourth frames D without the balustrade support BS at side S3 may comprise securing means (e.g., plug/socket) for further extending a series of fourth frames D. However, the fourth frame D that comprises the balustrade support BS at side 83 may be configured to reside at a perimeter edge of the outdoor decking structure, and may optionally omit securing means for further extending the series of fourth frames D. Although in the preceding examples the second and fourth frames B, D are described as having optional balustrade supports BS, it would be appreciated that the balustrade supports BS may be an optional feature of the first frame A and/or an optional feature of the third frame C. Referring now to the fifth frame E of FIG. 9, the fifth frame E may have many of the above-described features of the fourth frame D, except that the fifth frame E is non-rectilinear in plan view. For example, the fifth frame E comprises a peripheral frame member PFM that extends diagonally in plan view. The fifth frame E can be used to create a clipped corner effect for the outdoor decking structure 1 in plan view.

The preceding examples refer to four types of frames. In an implementation 30 comprising fewer types of frames, the fourth frame D could be omitted and instead the third frame C could be compatible with side S2 of the second frame B as well as side S2 of the first frame A, or the second frame B could be compatible with side S3 of the third frame C as well as side S3 of the first frame A. It would be appreciated that fewer types of frames can be used if they are more similar (e.g., similar securing means and/or leg patterns). However, more frame types enable each frame type to be optimised for material savings.

In the preceding examples, the third and fourth frames C, D are handed with respect to the first and second frames A, B. The second and fourth frames B, D are handed with respect to the first and third frames A, C. In further examples, opposite-handed variants of each frame type can be provided, to build from the first frame A in more directions than those shown in FIG. 2.

As used here 'module' refers to a unit or apparatus that excludes certain parts/components that would be added by an end manufacturer or a user.

Although embodiments of the present invention have been described in the preceding paragraphs with reference to various examples, it should be appreciated that modifications to the examples given can be made without departing from the scope of the invention as claimed. For example, a non-metal of equivalent strength per unit weight be used for the frame members FM.

Features described in the preceding description may be used in combinations other than the combinations explicitly described.

Although functions have been described with reference to certain features, those functions may be performable by other features whether described or not Although features have been described with reference to certain embodiments, those features may also be present in other embodiments whether described or not.

Whilst endeavoring in the foregoing specification to draw attention to those features of the invention believed to be of particular importance it should be understood that the Applicant claims protection in respect of any patentable feature or combination of features hereinbefore referred to and/or shown in the drawings whether or not particular emphasis has been placed thereon.
