Description of Embodiments
[0039] With reference to Figure 1, temporary barrier fencing 100 comprises support feet 101 which, with reference to Figure 6, support posts 103 of adjacent fence panels 104.
[0040] Each panel 104 may comprise a lower crossbar 105 and each post 103 may extend beyond the crossbar 105 to engage the foot 101.
[0041] The panel 104 comprises a post 103 (referred to herein as a bracing post 103A) at one end which comprises a brace 106 which braces a post 103 of an adjacent panel 104 in use.
[0042] The panel 104 comprises a post 103 (referred to herein as a locking post 103B) at an opposite end which keys the foot 101 depending on the orientation of the panel 104 with respect to the foot 101.
[0043] The panels 104 may be arranged in alignment to form the fencing 101 wherein each foot 101 is engaged by a bracing post 103A and a locking post 103B of adjacent panels 104. In embodiments, at least one panel 104 may comprise a bracing post 103A or a locking post 103B at one end and a normal post and an opposite end.
[0044] As shown in Figure 6, the brace 106 may narrow to a plate which comprise an aperture therethrough through which the locking post 103B inserts. The locking post 103B can rotate within the aperture, such as wherein the aperture is circular and the locking post 103B is similarly cylindrical.
[0045] The brace 106 may extend from the lower crossbar 105. In the embodiment shown in Figure 8, the lower crossbar 105 tapers to form the brace 106. In the embodiment shown in Figure 19, a plate is welded to an undersurface of the crossbar 105 to form the brace 106. In the embodiment shown in Figure 8, an angled plate may be welded to an open end of the crossbar 105 (or inserted therein) to form the brace 106.
[0046] With reference to Figures 8 and 9, the foot 101 may comprise a pair of post apertures 107 within which the posts 103 insert adjacently.
[0047] With reference to Figure 6, the bracing post 103A may be inserted into a first aperture 107A wherein the aperture of the brace 106 collocates with a second post aperture 107B. The locking post 103B is then inserted through the aperture of the brace 106 to engage the second post aperture 107B.
[0048] The locking post 103B may define a key 108 which slots into a corresponding keyhole 109 within the aperture 107. The key 108 and the keyhole 109 may be configured such that the key 108 can only insert into the keyhole 109 depending on the orientation of the panel 104 with respect to the foot 101. As shown in Figures 9 and 12, the keyholes 109 may be orientated at 45° with respect to an orthogonal axis of the foot 101.
[0049] As such, when inserting the locking post 103B into the foot 101 through the brace 106, the panel 104 may be orientated at 45° with respect to the foot 101.
[0050] Once the key 108 is inserted through the keyhole 109, the panels 104 are then aligned so that the locking post 103B cannot be pulled from the second aperture 107B.
[0051] The brace 106 holds the posts 103 in alignment so that the foot 101 cannot be rotated with respect to the aligned panels 104 to attempt to disengage the locking post 103B.
[0052] As is shown in Figure 8, the keyhole 109 may be recessed a certain depth within the aperture 107 and wherein the key 108 extends further from a distal end of the locking post 103B as compared to the bracing post 103A. As such, the bracing post 103A may freely insert into the first post aperture 107.
[0053] It should be appreciated from the configuration of the key 108 and the keyhole 109 that the locking post 103B may also lock to the foot 101 when the panels 104 are orthogonal with respect to each other. In other words, the 45° orientation of the key 108 and the keyhole 109 allows for the arrangement of temporary barrier fencing 100 straight and orthogonally.
[0054] In embodiments, the orientations of the keyholes 109 may be configured so that the locking post 103B locks to the foot 101 at 45°.
[0055] Figure 4 shows a key piece 110 having the key 108 and comprising a collar 111 which can be retrofitted into an open end of the locking post 103B. The collar 110 may be welded to the locking post 103B in the correct orientation.
[0056] Whereas the embodiments of Figures 6 - 9 show the foot 101 comprising post apertures 107 into which the posts 103 insert, Figures 18 and 19 show an embodiment wherein the foot 101 comprises a base frame 112 supporting a pair of uprights 113 which insert into open ends of the posts 103.
[0057] Furthermore, both uprights 113 may comprise a key 108 either of which may slot into the keyhole 109 of the locking post 103B. Figure 16 shows an insertable collar 114 defining the keyhole 109 which may be retrofitted into an open end of the locking post 103B. Figure 17 similarly shows an embodiment wherein the key piece 110 may be retrofitted to the uprights 113.
[0058] As shown in Figure 1, the fencing 100 may comprise upper fence panel retainers 127 which prevent the posts 103 from being prised apart. The retainer 127 may comprise a proximal piece 130, a cross piece 129 and an insertion piece 128.
[0059] With reference to Figure 3, the proximal piece 130 may be affixed to the locking post 103B and the insertion portion 128 may insert into the bracing post 103A as the locking post 103B engages the foot 101.
[0060] As can be appreciated, when the locking post 103B is locked to the foot 101, the retainer 127 further prevents the bracing post 103A from being lifted from the foot 101 because an upper end of the bracing post 103A hits the cross piece 129.
[0061] As is further shown in Figure 3, the insertion piece 128 may have sufficient length so that a distal end thereof remains within the bracing post 103A as the locking post 103B disengages from the foot 101. In other words, the length of the insertion piece 128 is sufficient to prevent disconnection of the retainer 127 whilst the locking post 103 is locked to the foot 101.
[0062] Figure 5 illustrates how a retainer piece 127 may be retrofitted to the locking panel 104B which comprises a collar 129 which engages within an opening of the locking post 103B. The collar 129 may be welded to the post 103.
[0063] Figures 10 - 12 show an embodiment wherein the foot 101 comprises a moulded shell 115 which may be filled with ballast such as sand or water. The shell 115 may be formed by an upper shell piece 116A which is connected to a lower shell piece 116B.
[0064] The foot 101 may comprise a plurality of pairs 117 of post apertures 107 for engaging the post 103 adjacently therein at different positions. In the embodiment shown, the foot 101 is substantially rectangular and wherein the pairs 117 are arranged along the length thereof. As such, in the manner shown in Figure 2, a post 103 may engage the foot 101 centrally so that the foot 101 braces the panel 104 equally either side or alternatively from one end for cantilevered support.
[0065] As shown in Figure 12, the pairs of apertures 117 may comprise keyed pairs 117A and non-keyed pairs 117B.
[0066] With reference to Figure 10, an upper surface 118 of the foot 101 may comprise an arrangement of studs 119 extending from the upper surface 118 and, with reference to Figure 11, a lower surface 120 thereof may comprise a corresponding arrangement of conforming recesses 121.
[0067] The studs 119 and the recesses 121 allow plastic moulded feed 101 to be stacked in a variety of configurations in the manner shown in Figure 2. As is shown, the plastic moulded feed 101 may be stacked directly atop each other or alternatively across each other.
[0068] The studs 119 and the recesses 121 may be noncircular but which comprise orthogonal symmetry, such as being octagonal, allowing for orthogonal interconnection.
[0069] Figure 14 shows an embodiment comprising a foot cover 122 which covers the foot 101, which is shaped to define a ballast void 124 therein and which cannot be removed from the foot 101 when the locking post 103B is locked to the foot 101.
[0070] The cover 122 may be made of moulded plastic. The cover 122 may comprise a pair of post apertures 123 for the posts 103 to engage the foot 101 therethrough.
[0071] With reference to Figure 15, the cover 122 is shaped to define a ballast void 124 suitable for sandbags 125.
[0072] The cover 122 cannot be lifted from the foot 101 when the posts 103 are engaged thereto, thereby preventing the unauthorised removal of the ballast.
[0073] The cover 122 may be elongate and the apertures 123 may be centrally located so that the cover 122 extends from either side of the panel 104. In this way, the cover 122 may conceal ballast (such as a pair of sandbags 125) on either side of the panel 104.
[0074] The cover 122 may entirely conceal the foot 101. In other words, the cover 122 may define a lower edge which has a greater cross-section than that of the foot 101 so that the cover 122 entirely conceal the foot 101 therein in the manner shown in Figure 15.
[0075] The cover 122 may define a saddle 126 thereacross having the apertures 123 therethrough. The saddle 126 presses against the crossbars 105 of the panels 104 to prevent the cover 122 from being lifted from the foot 101 when the posts 103 are locked to the foot 101 yet whilst allowing a sufficient ballast void 124.
[0076] In embodiments, the brace 106 may extend approximately 128 mm from an edge of the bracing post 103A. Furthermore, where the brace 106 comprises an aperture therethrough, the aperture may comprise a diameter of approximately 36 mm and allow a distal edge of approximately 10 mm. Where the brace 106 comprises a plate, the plates may be approximately 8 mm thick.
