FIELD OF INVENTION

[0001] The present invention relates to the field of temporary fencing.

[0002] In one form, the invention relates to a fence panel suitable for temporary fencing.

[0003] In one particular aspect the present invention relates to a fence panel manufactured from polymers, particularly recycled plastic, for temporary fencing.

[0004] In another aspect the present invention relates to a fencing system comprising one or more fence panels and components for connecting the panels to form a temporary fence.

[0005] It will be convenient to hereinafter describe the invention in relation to temporary fencing for restricting access to building sites, defining paths for foot passage and crowd control or vehicle passage or parking, however it should be appreciated that the present invention is not limited to that use only and could be temporary fencing used for other purposes, such as screening or treillage in gardening applications.

BACKGROUND ART

[0006] It is to be appreciated that any discussion of documents, devices, acts or knowledge in this specification is included to explain the context of the present invention. Further, the discussion throughout this specification comes about due to the realisation of the inventor and/or the identification of certain related art problems by the inventor. Moreover, any discussion of material such as documents, devices, acts or knowledge in this specification is included to explain the context of the invention in terms of the inventor's knowledge and experience and, accordingly, any such discussion should not be taken as an admission that any of the material forms part of the prior art base or the common general knowledge in the relevant art in Australia, or elsewhere, on or before the priority date of the disclosure and claims herein.

[0007] Temporary fencing is a commonly used as an interim barrier for security, public safety, crowd or vehicle control, theft deterrence or to delimit an area to which access is restricted. Temporary fencing is a self-supporting and modular system which is interlocking and can be readily assembled, disassembled for transport or storage, then re-assembled. It is important that the assembled fencing remains erect and stable at all times. Preferably the disassembled temporary fencing panels can be horizontally flat stacked to a safe height.

[0008] Typically, a temporary fencing system includes components such as panels, infills, support feet and braces.

[0009] In Australia temporary fencing must meet the requirements of Australian Standard AS4687:2022 set by Standards Australia with testing conducted by National Association of Testing Authority (NATA) accredited engineers. The temporary fencing must be able to pass:

• a climbing test that requires the fence to support a 65 kg load applied centrally to the middle of top horizontal frame member at a leer arm of 400 mm for 3 minutes,

• an impact test carried out in 4 different test locations on the panel, that requires the fence to withstand an impact by a 37 kg weight, applying 150 joules of impact energy from a 150 mm diameter torisphe rica I ly shaped indenter,

• a wind strength test, that requires that the fence does not overturn when exposed to high winds, and

• measurement confirming that the aperture size of any mesh does not exceed 75 mm, and a 76 mm x 76 mm cube shaped block cannot pass through the apertures,

• a load test to ensure that the individual parts of the mesh can sustain a load of 1.0 kN for a minimum of 60 sec without deflection of the mesh exceeding 35 mm.

[0010] Materials of construction for temporary fencing in Australia must comply with Section 2 of Australian Standard AS4687:2022, and are typically chosen from chain-link, steel wire and plastic panel or mesh. Plastic has become increasingly popular in recent times due to its readily availability, light weight, strength and ease of processing during manufacture. Plastic components can be manufactured using a range of methods including injection moulding, extrusion blow moulding, mesh extrusion and rotational moulding. Recycled plastics are emerging as a convenient and viable source of material for manufacture of temporary fencing.

[0011] Temporary fencing is used in a vast number of locations. Temporary fencing for enclosing construction sites and industrial sites may comprise robust hoarding panels, or alternatively, mesh panels if visibility of the construction site is necessary. The mesh may be metal, or alternatively made from soft or hard thermoplastics such as polyvinyl chloride (PVC), polypropylene (PP) or polyethylene (PE) which are processed via a specialised mesh extrusion machine.

[0012] The mesh panels may be supported by feet such as those referred to as 'polyblocks', comprising a heavy, 26 to 32 kg block as a counterweight for the fence panel, adapted to receive the end of a panel support post. In addition, the mesh panels may need bracing because the greater the length of a straight fence, the more unstable it becomes. The feet may be configured for support or attachment of a fence brace.

[0013] Temporary fencing such as Endurafence™ and Strongwall™ fencing (from Oxford Plastic Systems Ltd) comprise anti-climb panels that can be coupled together horizontally to form a length of fencing, and/or vertically to a height of two panels. The vertical height is typically one panel in height for street works, so that drivers and pedestrians can see over the fencing. The fencing may be two panels in height for construction sites and other locations where restricting entry is of paramount importance.

[0014] Temporary fencing for traffic control often consists of interlocking plastic panels that are no higher than car drivers' line of sight and may have swivel feet to assist stackability (known as 'kwikstak' barriers). Some comprise interlocking hollow plastic free-standing panels (known as 'kwikblock' barriers) that can be filled with sand or water for added weight and stability and to withstand slow impact from vehicles. Kwikblock barriers are typically manufactured by rotational moulding, which is a technique commonly used to manufacture large plastic products that do not have fine details. Kwikblock barriers are made from high density polyethylene (HDPE), including recycled HDPE, but due to low volume availability, the cost of recycled HDPE can be as much as virgin HDPE.

[0015] Temporary fencing for controlling queues, or crowds at large sporting events and concerts tends to be lightweight, stackable, about 1 metre in height and provide good through- visibility. Typical fence panels of this type comprise a lightweight rectangular tubular steel frame with in-fill comprising welded vertical metal bars, and removable supporting feet. Adjacent panels are releasably connected by a hinge system. Another fence panel of this type is made by Replas Plastics Australia Pty Ltd and instead of vertical metal bars, the fence panel has vertical plastic pickets to resemble the wooden picket fencing that has traditionally been used at cricket grounds. The Replas product is manufactured from recycled soft plastics collected from supermarkets and consists of 90% polypropylene mixed with additives.

[0016] There is an ongoing need for temporary fencing that complies with mandatory strength requirements yet is simple to manufacture and assemble.

SUMMARY OF INVENTION

[0017] An object of the present invention is to provide an alternate to existing temporary fence panels.

[0018] Another object of the present invention is to provide an alternate to existing polymeric temporary fencing panels, particularly temporary fencing panels comprising recycled plastic.

[0019] A further object of the present invention is to alleviate at least one disadvantage associated with the related art.

[0020] It is an object of the embodiments described herein to overcome or alleviate at least one of the above noted drawbacks of related art systems or to at least provide a useful alternative to related art systems.

[0021] In its simplest form the present invention provides a panel for construction of a section of fence, a screen or treillage, the panel comprising an infill sheet, such as a mesh, and a frame which substantially encloses the perimeter of the infill sheet and includes a portion of frame that projects beyond the perimeter of the infill sheet.

[0022] In one embodiment, the panel is of unitary polymer construction, the polymer including recycled plastic.

[0023] In a first aspect of embodiments described herein there is provided a panel, typically for construction of fencing, the panel comprising: a mesh having opposed front and rear sides and transverse openings, the mesh being integral with a frame having, a first elongate section adjacent a first portion of the mesh, a second elongate section transverse to the first elongate section and adjacent a second portion of the mesh, and a third elongate section parallel to the first elongate section and adjacent a third portion of the mesh and having an extension projecting therefrom.

[0024] The frame may optionally have a fourth elongate section parallel to the second elongate section and adjacent a fourth portion of the mesh.

[0025] Preferably the first elongate section and second elongate section meet at a chamfer.

[0026] Typically, the mesh is planar and rectangular, with rectangular transverse openings. Transverse openings of alternate geometric configurations are also within the scope of the present invention.

[0027] Typically, the frame is integral with the perimeter of the rectangular mesh and with two elongate sections adapted to interconnection with other panels to form a section of fencing. Preferably the panel is of unitary construction and entirely moulded of polymer material, preferably comprising recycled plastic. In a preferred embodiment at least a major portion of the polymer comprises high-density polyethylene (HDP) or poly-ethylene terephthalate (PET).

[0028] The frame may additionally include cross-braces or other structural features to maintain the strength of the frame or panel or to make it easier to manufacture from polymer material.

[0029] The panel of the present invention is configured such that two, or four identical panels can be interconnected to form a section of fencing.

[0030] In a second aspect of embodiments described herein there is provided a fence section comprising two panels according to the present invention, the fence section comprising: a first base panel and a second base panel, wherein the first elongate section of the first and second base panels are releasably connected.

[0031] The fence section may further comprise feet for support, that is, a first foot for receiving the extension of the third elongate section of the first base panel, and a second foot for receiving the extension of the third elongate section of the second base panel. The feet may be of a type well known in the industry for receiving a support post or other elongate section of temporary fencing. [0032] While two panels can be interconnected to form a relatively low section of fencing, such as for use as a crowd control barrier, or a garden screen or garden trelliage, two further panels can also be interconnected to form a section of fencing having larger dimensions.

[0033] In a third aspect of embodiments described herein there is provided a fence section comprising four panels according to the present invention, the fence section comprising: a first base panel and a second base panel, wherein the first elongate section of the first and second base panels are releasably connected, a first top panel and a second top panel, wherein the first elongate section of each of the first and second top panels are releasably connected, and the second elongate sections of the first top panel and the first base panel are releasably connected, and the second elongate sections of the second top panel and the second base panel are releasably connected.

[0034] In this configuration the chamfer of a top panel neatly abuts a chamfer of a base panel in the centre of the fence section. A central joiner may be associated with the abutting chamfers. The central joiner may assist in retaining the chamfers in abutment. Alternatively, or in addition, the central joiner may bear markings such as a trade mark or logo to indicate ownership of the fencing or the property being fenced, or information such as a warning not to proceed past the fence panels.

[0035] Again, the fence section may further comprise a first foot for receiving the extension of the third elongate section of the first base panel, and a second foot for receiving the extension of the third elongate section of the second base panel.

[0036] The fence panel and fence section may be manufactured in any convenient dimensions. The dimensions of the fence section may be increased by one or more insert panels located between each pair of panels. Larger dimension panels and fence sections according to the present invention can be manufactured to comply with relevant standards, such as AS 4687:2023, but for some applications, compliance with manufacturing or performance standards may not be necessary. Smaller dimension and lighter weight panels and fence sections according to the present invention may be appropriate for use in screening or as trellis works for gardening or landscaping applications. [0037] In a preferred embodiment the pairing of the first base panel and first top panel is separated by an insert panel from the pairing of the second base panel and second top panel.

[0038] In a fourth aspect of embodiments described herein there is provided a fence section comprising four panels according to the present invention, the fence section comprising: a first base panel and a second base panel, wherein the first elongate section of the first and second base panels are releasably connected to an insert panel, a first top panel and a second top panel, wherein the first elongate section of each of the first and second top panels are releasably connected to the insert panel, and the second elongate sections of the first top panel and the first base panel are releasably connected, and the second elongate sections of the second top panel and the second base panel are releasably connected.

[0039] Typically, the insert panel is rectangular and may include two or more insert sub-panels.

[0040] The releasable connections between panels may be of any convenient type or configuration. For example, the elongate sections may include holes or recesses that can be aligned to receive a fixing means such as a polymer screw, cotter pin or the like. In another embodiment the panels may be configured such that adjacent elongate sections can releasably interlock, such as by sliding fit, interference fit or snap fit. However, many other releasable connections will be readily apparent to those skilled in the art including nuts and bolts and plastic rivets having an end that can be melted to form a seal.

[0041] In a fifth aspect of embodiments described herein there is provided a fence comprising two or more fence sections according to the present invention. The extension of the third elongate section of the base panels of adjacent fence sections may optionally be connected by a shared foot or other suitable means.

[0042] The extension of the third elongate section of the top panels of adjacent fence sections may optionally be fastened by a joiner such as a joining clamp, joining hood, joining strap or other suitable mechanical means.

[0043] In a sixth aspect of embodiments described herein there is provided a method of constructing a fence section comprising the steps of: providing a first, a second, a third and a fourth fence panel according to the present invention, releasably connecting the first elongate sections of the first panel and the second panel, releasably connecting the first elongate section of the third and fourth panels, releasably connecting the second elongate sections of the first panel and the third panel, and releasably connecting the second elongate sections of the second panel and the fourth panel.

[0044] The method may also optionally include: releasably connecting the extension of the third elongate section of the first panel to a first foot, and releasably connecting the extension of the third elongate section of the second panel to a second foot.

[0045] In a seventh aspect of embodiments described herein there is provided a method of constructing a fence section comprising the steps of: providing a first, a second, a third and a fourth fence panel according to the present invention, releasably connecting the first elongate sections of the first panel and the second panel to opposing edges of a first insert panel, releasably connecting the first elongate section of the third and fourth panels to the opposing edges of a second insert panel, releasably connecting the second elongate sections of the first panel and the third panel, and releasably connecting the second elongate sections of the second panel and the fourth panel.

[0046] In one embodiment the first insert panel and second rectangular insert panels are integral.

[0047] Smart Identification Tagging [0048] In a particularly preferred embodiment, the components of the fencing, including panels of the present invention may include smart identification tags for asset tracking and inventory management.

[0049] The smart identification tags may include, for example, barcodes, QR codes, passive or active radio frequency identification (RFID) tags. Smart identification tags are useful to search, identify and track the fence components and for efficient control of inventory during storage, transport and use of the fence components. The smart identification tags may be in any convenient form, such as a smart label, or smart chip embedded in the material of a fence component.

[0050] Sensors

[0051] In a particularly preferred embodiment, the components of the fencing, including panels of the present invention may include sensors for sensing the geographical location, or orientation of components of the fencing, including panels.

[0052] Other aspects and preferred forms are disclosed in the specification and/or defined in the appended claims, forming a part of the description of the invention.

[0053] In essence, embodiments of the present invention stem from the realisation that a single configuration of panel can be used to provide a section of fencing, such as temporary fencing without the need for other types of panels. Furthermore, it has been realised that it possible to manufacture the desired configuration from polymer, such as recycled plastics, to the required statutory manufacturing or performance standard for temporary fencing.

DETAILED DESCRIPTION

[0058] For purposes of description herein, the terms "upper," "lower," "right," "left," "rear," "front," "vertical," "horizontal," "interior," "exterior," and derivatives thereof shall relate to the invention as oriented in FIG. 3 and relative to the x-, y- and z- directions indicated by the axes indicated on the drawings. However, it is to be understood that the invention may assume various alternative orientations, except where expressly specified to the contrary. It is also to be understood that the specific devices and processes illustrated in the attached drawing and described in the following specification are simply exemplary embodiments of the inventive concepts defined in the appended claims. Hence, specific dimensions and other physical characteristics relating to the embodiments disclosed herein are not to be considered as limiting, unless the claims expressly state otherwise. Additionally, unless otherwise specified, it is to be understood that discussion of a particular feature of component extending in or along a given direction or the like does not mean that the feature or component follows a straight line or axis in such a direction or that it only extends in such direction or on such a plane without other directional components or deviations, unless otherwise specified.

[0059] FIG 1 illustrates a temporary fence panel of the prior art. FIG 1A illustrates the panel components, namely a frame comprising support posts 1 and cross members 2, to which is attached a wire mesh panel infill 3. The frame is typically about 1800-2200 mm in height and 2400- 2500 mm in width. The frame is supported by counter weights 4 that are heavy, and about 100- 200 mm in height.

[0060] The mesh is shown in close-up in Fig IB. The wire 6 has a thickness of 4mm, the width of the apertures is 50mm and the length is 200mm. Fence clamps 7 illustrated in Fig 1C are clamped to the posts of adjacent panels to secure them together to form sections of fencing.

[0061] FIG 2A illustrates one embodiment of a temporary fence panel 10 according to the present invention. The panel includes a mesh 11 in the form of a generally rectangular planar infill having opposed front and rear sides. In this view the mesh 11 is viewed from the front side and has rectangular transverse openings.

[0062] The mesh 11 is integrally formed with a frame 12 having three elongate sections (12a, 12b and 12c) that substantially enclose three sides of the perimeter of the rectangular mesh infill. The first elongate section 12a is adjacent a first portion of the mesh 11. The second elongate section 12b is transverse to the first elongate section 12a and adjacent a second portion of the mesh 11. The first and second elongate sections meet at a chamfer 13.

[0063] The third elongate section 12c is parallel to the first elongate section 12a and adjacent a third portion of the mesh. The third elongate section 13 also extends beyond the mesh 11. [0064] FIG 2B and FIG 2C illustrate two further embodiments of a temporary fence panel according to the present invention. The figures are annotated as listed above with analogous parts numbered with the prefix '1' for the embodiment shown in FIG 2B and the prefix '2' for the embodiment shown in FIG 2C. For example, the mesh in the embodiment of FIG 2A is numbered 11, while the analogous mesh in the embodiment of FIG 2B is numbered 111, and the analogous mesh in the embodiment of FIG 2C is numbered 211.

[0065] Typically, fence panels according to the present invention are manufactured of polymer. Preferably some or all of the polymer is recycled polymer.

[0066] The embodiment of the fence panel shown in FIG 2B is substantially identical to the fence panel 10 of FIG 2A except that the mesh 111 includes transverse openings of a different shape. Specifically, the transverse openings of the mesh 111 are substantially oval in shape. The oval shape provides particular advantages relating to mould flow if the panel is manufactured from polymer. The oval shape allowing easier injection moulding and reduced flow time in manufacture.

[0067] The mesh 111 is integrally formed with a frame 112 having three elongate sections (112a, 112b and 112c) that substantially enclose three sides of the perimeter of the rectangular mesh infill. The first elongate section 112a is adjacent a first portion of the mesh 111. The second elongate section 112b is transverse to the first elongate section 112a and adjacent a second portion of the mesh 111. The first and second elongate sections meet at a chamfer 113.

The third elongate section 112c is parallel to the first elongate section 112a and adjacent a third portion of the mesh. The third elongate section 112d also extends beyond the mesh 111.

[0068] The embodiment of the fence panel shown in FIG 3C is also substantially identical to the fence panel 10 of FIG 2A except that the mesh 211 includes transverse openings of a diamond shape. The frame also includes four elongate sections (212a, 212b, 212c and 2.2d), the first and second elongate sections meeting at a chamfer 213. The third elongate section 212c and fourth elongate sections 212f are of denser or solid construction compared to the first section 212a and second section 212b which comprise multiple parallel struts that have periodic transverse connections. The panel also includes a pair of transverse struts 212e, 212f positioned diagonally on the mesh to add rigidity and strength to the panel. [0069] FIG 3A illustrates in perspective view, the panel 10 of FIG 2A, which is releasably connected to three identical panels to form a fence section. The fence section 50 comprises a first base panel 40, a second base panel 30, a first top panel 10 and a second top panel 20. This shows how a single panel configuration is used to form the much larger fence section.

[0070] The first base panel 30 and second base panel 40 are releasably connected together at their respective first elongate sections 32a (and 42a, not visible).

[0071] The first top panel 10 and second top panel 20 are releasably connected together at their respective first elongate section 12a (and 20a, not visible).

[0072] The first top panel 10 and the first base panel 40 are releasably connected together at their respective second elongate sections 12b (and 42b, not visible).

[0073] The second top panel 20 and the second base panel 30 are releasably connected together at their respective second elongate sections 32b (and 20b, not visible).

[0074] FIG 3B illustrates in front view, the panel 210 of FIG 2C, which is releasably connected to three identical panels to form a fence section. The fence section 250 comprises a first base panel 240, a second base panel 230, a first top panel 210 and a second top panel 220. This shows how a single panel configuration is used to form the much larger fence section.

[0075] In this embodiment the fence section 250 is shown to be supported by a pair of supports. For example, the supports may comprise a pair of counterweights 290, 291 adapted to receive the extension of the third elongate section of the first base panel 240, and a second base panel 230 respectively. The counterweights may be of any type well known in the industry, such as Polyblock fence feet. The counterweight preferably comprises a concrete or polymer block having a recess for receiving the extension of the third elongate section to create a high fulcrum point offering enhanced stability. The counterweight may optionally be configured to include cross bracing or a strut to provide further support of the fence section.

[0076] The fence section shown in FIG 3B also includes a central joiner 250 associated with the abutting chamfers. The central joiner 250 may assist in retaining the chamfers in abutment. Alternatively, or in addition, the central joiner may bear markings such as a trade mark or logo to indicate ownership of the fencing or the property being fenced, or information such as a warning not to proceed past the fence panels.

[0077] FIG 3C illustrates a fence section similar to that shown in FIG 3B, having a different type of diamond shaped mesh 11.

[0078] FIG 4A illustrates a close-up view of part of the mesh 11 of the fence panel 10 of FIG 2A. In this embodiment the mesh 11 comprises an array of rectangles defining openings oriented in a transverse direction (that is, in the direction of the z-axis).

[0079] FIG 4B illustrates the mesh 11 of the fence panel of FIG 4A in cross section along A-A'. The mesh is manufactured from one or more polymers, preferably derived from recycled plastic and this view shows the generally ellipse shaped cross section 51 of the polymer forming the mesh 11. The primary benefit of the ellipse shaped cross section relates to mould flow, allowing easier injection moulding and reduced flow time in manufacture. The dimensions of the ellipse shape are driven by the need to comply with temporary fencing standards (particularly enhancing the anti-climb aspects of the Australian standards for temporary fencing).

[0080] FIG 5 illustrates the mesh 11 of the fence section of FIG 3C in the region enclosed by the circle (C). In this view it can be seen that the mesh 11 is integrally formed with the third elongate section 212c. The third elongate section 212c comprises multiple parallel struts 213 joined periodically by transverse connections 214. The mesh 11 and third elongate section 212c are formed from polymer, preferably comprising recycled polymer

[0081] FIG 6 is a close up view of the central joiner 250 of the fence panel of FIG 3B. The central joiner 250 assists in retaining the chamfers in abutment and sits at the intersection of struts 212f, 222f, 232f and 242f. The central joiner may assist in retaining the chamfers in abutment. Alternatively, or in addition, the central joiner may bear marking such as a trade mark or logo to indicated ownership or the fencing or the property being fenced, or information such as a warning not to proceed past the fence panel. The central joiner may also include a sensor to sense a characteristic of the panels such as the location or orientation.

[0082] FIG 7 illustrates a perspective view of a fence section comprising four panels 110 configured as shown in FIG 2A that are releasably connected to three identical panels to form a fence section. The fence section 150 comprises a first base panel 140, a second base panel 130, a first top panel 110 and a second top panel 120.

[0083] FIG 8 illustrates a close-up view of part of the mesh 111 of the fence panel 110 of FIG 2A. In this embodiment the mesh 111 comprises an array of substantially oval shaped transverse openings (that is, they open in the direction of the z-axis).

[0084] FIG 9 illustrates the mesh 111 of the fence panel of FIG 8 in cross section along B-B'. The mesh is manufactured from one or more polymers, preferably recycled plastic and in this view, it is possible to see the generally H-shaped cross section 151 of the polymer forming the mesh 111.

[0085] FIG 10 illustrates in expanded view, four panels of the present invention according to FIG 2A partly assembled to form a fence section. FIG 11 illustrates the fully assembled fence section of FIG 10. In this view it is possible to see how the chamfer of the first top panel 10 meets the chamfer of the second base panel 30 at the centre of the fence section 50. On the other side of the fence section 50 (not visible), the chamfer of the second top panel 20 meets the chamfer of the first base panel 40 at the centre of the fence section 50.

[0086] Figure 12 illustrates three fence sections 50, 51,52 of the type depicted in FIG 11 positioned to form part of a continuous fence. The fence sections 50, 51,52 are anchored by counterweights, 90, 91, 92 and 93 which each have one or more recesses for snugly receiving an extension of the third elongate section of a base panel. The counterweight is made of dense material and creates a high fulcrum point offering enhanced stability. In this view, counterweight 91 receives the third elongate section of the first base panel 40 of fence section 50, and a second base panel 30 of fence section 51. Counterweight 92 receives the third elongate section of the first base panel 40 of fence section 51, and a second base panel 30 of fence section 52.

[0087] The counterweights 90 and 93 at either end of the fence in this configuration only receive a single third elongate section of second base panel 30 and first base panel 40, respectively. However, it will be appreciated that further fence sections could be added to either end of the fence.

[0088] If necessary, the temporary fencing may be further supported and stabilised by the inclusion of a strut braced against the counterweight. [0089] FIG 13 illustrates the fence section as illustrated in FIG 3C comprising four panels with an insert located between pairs of fence panels according to the present invention;

[0090] Typically, the dimensions of a fence section according to the present invention would be 2.4m in width and 2.1m in height. In many applications, a wider fence section is required, nominally 3.3m to 3.4m in width and 2.1 m in height. FIG 13 illustrates a fence section according to the present invention having increased width due to the inclusion of an insert panel 260 located between pairs of panels.

[0091] More specifically, the fence section comprises four panels 210, 220, 230 and 240 according to the present invention. The first base panel 240 and a second base panel 230 are releasably connected to one edge of the insert panel 260 along their respective first elongate sections 230a and 240a. The first top panel 210 and a second top panel 220, are releasably connected to one edge of the insert panel 260 along their respective first elongate sections 210a and 220a.

[0092] As shown, in this embodiment the insert panel 260 is rectangular and one two pairs of panels (210 and 240) are releasably connected to one side of the rectangular insert panel 260, while the other pair of panels (220 and 230) are releasably connected to the other side of the rectangular insert panel 260.

[0093] The second elongate sections of the first top panel 210 and the first base panel 240 are releasably connected as previously described. The second elongate sections of the second top 220 panel and the second base panel 230 are releasably connected as previously described.

[0094] In this embodiment the insert panel 260 is a unitary rectangular panel comprising a frame 261, mesh infill 261 and four cross braces 263, 264, 265, 266. However, it will be appreciated that other configurations of the insert are contemplated by the present invention and may include, for example two or more detachable insert sub-panels.

[0095] In this embodiment the fence section includes two central joiners 251 and 252 for stability. [0096] The extension of the third elongate section of the top panels of adjacent fence sections may optionally be fastened by a joiner such as a joining clamp, joining loop or other suitable mechanical means. FIG.s 14 and 15 illustrate two such joiners.

[0097] FIG 14 illustrates a joining clamp 300 according to the present invention showing a first half 301 in perspective front view (FIG 14A) and a second half 302 in perspective rear view (FIG 14B). Each half 301, 302 of the clamp 300 comprises a substantially rectangular block having two arched sections 303, 304 located on either side of a recess 305 that passes transversely through the block. When the two halves 301 and 302 are brought together the two pairs or arches (304a/304b and 305a/305b) align to form a cylindrical shaped recess which can receive the respective extensions of the third elongate section of the top panels of adjacent fence sections. A bolt or other fastener may be passed through the recess 305 to hold the two halves 301 and 302 in abutment.

[0098] FIG 15 illustrates a joining hood 320 according to the present invention shown in perspective side view (FIG 15A) and in perspective top view (FIG 15B). The joining hood 320 comprises a substantially oval body having an internal wall defining a circular transverse opening 321 and an oval transverse opening 322. In use the circular opening 321 receives an extensions of the third elongate section of the top panel of a first fence section. The oval opening 322 receives an extensions of the third elongate section of the top panel of a second, adjacent fence section.

[0099] The oval opening 322 allows for some movement or play between the extensions so that the hood is easier to fit in place. The interior of the hood may include projections 323 to grip the extension so that the joining hood 320 remains in place.

[00100] FIG 16 illustrates a joining strap or cable tie, according to the present invention shown in top view (FIG 16A) and perspective view from below (FIG 16B). The joining strap is suitable for connecting adjacent fence sections. The joining strap comprises an elongate flexible strap 340 having a free end, the other end comprising an integral body 341 for releasably retaining the free end of the strap 340. The body 341 includes a jaw 342 comprised of two opposed grips 343, 344 such that applying compression to the body 341 causes the jaw 342 to open, and removal of the pressure allows the jaw to close. [00101] When pressure is applied to the body 341, the free end of the strap 340 can be passed through the jaw 342. When the pressure is removed the jaw 342 closes as the grips 343, 344 move together and retain the strap 340.

[00102] In the preferred embodiment shown in FIG 16 one grip 343 is generally H-shaped while the other grip 344 is generally U-shaped or rectangular shaped and is located between the arms of the H-shaped grip 343. The body 341 comprises a circular wall 345, integral with the two grips 343, 344 that are located in diametrically opposite positions within the circular wall. Application of pressure, such as finger pressure, on the outer surface of the circular wall 345 and perpendicular to the positions of the grips 343,344 causes the circular wall 345 to become more oval in shape, moving the grips 343, 344 apart. The free end of the strap 340 can thus be moved into or out of the jaw 342. Releasing pressure on the outer surface of the wall 345 allows it to relax back into a circular shape, and the grips 343, 345 move closer together gripping and entrapping the strap 340, resisting its movement.

[00103] The components as described and illustrated may include smart identification tags for asset tracking and inventory management.

[00104] The smart identification tags may include, for example, barcodes, QR codes, passive or active radio frequency identification (RFID) tags. Smart identification tags are useful to search, identify and track the fence components and for efficient control of inventory during storage, transport and use of the fence components. The smart identification tags may be in any convenient form, such as a smart label, or smart chip embedded in the material of a fence component.

[00105] The components as described and illustrated may include sensors for sensing the geographical location, or orientation of components of the fencing. Preferably the sensors can be remotely monitored, such as at a central monitoring location.

[00106] The ability to collect data regarding the geographical location of components is useful for keeping track of component inventory at different locations. Sensors may also be useful for tracking movement of components particularly in the case of theft. Sensors for recording data relating to the orientation of components are valuable indicators of fencing being breached. For example, a fence may be breached by unwarranted intrusion, or when bad weather causes a panel to blow over.
