DETAILED DESCRIPTION

(18) FIGS. 1 to 11 illustrate a first embodiment of an adjustable panel connector 100 according to the present invention which can be used to interconnect mesh panels 105 (FIGS. 6 to 11) that form part of a barricade, guarding barricade and/or guarding system or assembly.

(19) Referring firstly to FIGS. 1 to 3, the illustrated adjustable panel connector 100 generally comprises a first rectangular panel element 102 and a second rectangular panel element 104 interconnected along and about a connection axis X-X. Each of the first panel element 102 and the second panel element 104 include two spaced apart first fastening arrangements 106 configured for direct connection to portions of mesh panel, and a central joiner engagement aperture 108 configured for connection to a joiner arrangement (detailed below). The first panel element 102 and the second panel element 104 are interconnected using a connection arrangement 110 configured to lock the first panel element 102 at a selected angle relative to the second panel element 104 about the axis X-X.

(20) The illustrated pivot connection arrangement 110 comprises a hinge assembly having a pivot locking rod 112 which is received in a series of connector sleeves 116 which form part of each of the first panel element 102 and the second panel element 104. The pivot locking rod 112 comprises an elongate connection rod including a plurality of longitudinal ribs 114 (FIG. 3) extending around the circumference of the rod. Each of the first panel element 102 and the second panel element 104 include two spaced apart connector sleeves 116 aligned with and extending along the axis X-X. The pivot locking rod 112 is releasably received within a respective set of connector sleeves 116. The respective connector sleeves 116 of the first panel element 102 and the second panel element 104 interlace about and along the axis X-X. Each connector sleeve 116 includes an internal channel 118 (FIG. 3) having a complementary fluted configuration to the ribbed pivot locking rod 112. This complementary shape forms an interference fit between the pivot locking rod 112 and the connector sleeves 116, when the pivot locking rod 112 is received within the connector sleeves 116. This fit prevents rotation of the connector sleeves 116 around the pivot locking rod 112, thereby locking the position of the first panel element 102 and the second panel element 104 at a fixed angle relative to the axis X-X.

(21) The illustrated pivot locking rod 114 includes a flanged head 120 at a first end and a aperture 122 at the opposite end configured to receive a plug 124 (FIG. 3) once the pivot locking rod 112 is fitted into the connector sleeves 116. The illustrated plug 124 includes a series of ribs or barbs 126 extending along an elongate shaft 127. The barbs 126 create a tight friction fit within the aperture 122 to hold the plug 124 in place once inserted therein.

(22) The angle between the first panel element 102 and the second panel element 104 can be adjusted to match the required angle between two adjoining mesh panels and then locked into place by inserting the pivot locking rod 112 into the respective connector sleeves 116 of the first panel element 102 and the second panel element 104. This angle adjustment and lock enables a single connector to be used for connecting adjoining mesh panels together at a large variety of angles.

(23) FIG. 5 illustrates various angles that the first panel element 102 and the second panel element 104 can be angled about the axis X-X. As shown in FIG. 5(A), the base structures 129 of the first panel element 102 and the second panel element 104 can be brought to an angle .sub.1 of around 20 degrees apart, or could be fixed at a wider angle .sub.2 between the front faces 131 of the first panel element 102 (FIG. 5(B)) and the second panel element 104 of about 140 degrees, or can be angled with an angle .sub.3 between the front faces 131 of the first panel element 102 and the second panel element 104 of about 20 degrees (FIG. 5(C)).

(24) The first panel element 102 and the second panel element 104 include a number of fastening arrangements for attachment of the adjustable panel connector 100 to safety panels, preferably mesh panels 105.

(25) The illustrated first fastening arrangements 106 comprise rotating clamps configured to releasably hold selected cross-members near the edge of a mesh panel within the adjustable panel connector 100. As best shown in FIGS. 2 and 3, each first fastening arrangement 106 includes a first mesh receiving channel 130, a locking element 132 seated within the first mesh receiving channel 130, and a second mesh receiving channel 133. The first mesh receiving channel 130 and the second mesh receiving channel 133 are used to cooperatively secure the respective first panel element 102 or second panel element 104 to the selected section of mesh panel 105 (for example as shown in FIGS. 6 and 7).

(26) Each first mesh receiving channel 130 comprises an elongate channel which extends from each side of the first panel element 102 and the second panel element 104 and interconnects the spaced apart fastening arrangements 106 thereof. Each first mesh receiving channel 130 includes an opening, through which the longitudinal cross-members of a mesh panel can be received. Each first mesh receiving channel 130 also includes two lateral grooves 140 for receiving a lateral cross-member of the section of a mesh panel 105.

(27) The locking element 132 of each first fastening arrangement 106 comprises a generally cylindrical body which is held within the first mesh receiving channel 130. As shown in FIG. 3, the each locking element 132 can be laterally inserted and seated within the first mesh receiving channel 130. Each locking element 132 includes a locking channel 134 configured to receive a section of a cross-members a mesh panel 105 (for example as shown in FIGS. 6 and 7) and a handle 135 for manual rotational manipulation of the locking element 132 within the first mesh receiving channel 130.

(28) The locking element 132 is rotatably mounted within the first mesh receiving channel 130 and is movable between a receiving position (configuration (A) in FIGS. 2 and 7) in which the locking channel 134 is orientated to receive a section of a mesh panel, and a locking position (configuration (B) in FIGS. 2 and 7) in which the locking channel 134 is orientated within the first mesh receiving channel, causing the locking element 130 to engage around and/or over said section of the mesh panel and thereby fasten that section within the first mesh receiving channel 130.

(29) Each of the connector sleeves 116 of the first panel element 102 and the second panel element 104 include a mounting flange 145 forming the second mesh receiving channel 133 between the front face of the respective first panel element 102 and second panel element 104 near the axis X-X. As shown in FIGS. 6 and 7, the mounting flange 145 and the second mesh receiving channel 133 are configured to receive and hold edge cross-members 150 of a mesh panel 105. The next set of mesh cross-members 152 of the mesh panel 105 are then received within the first mesh receiving channel 130 and locked therein as described above. This creates two spaced apart locking points on the mesh panel 105.

(30) The spacing between the first mesh receiving channel 130 and the second mesh receiving channel 133 is configured to fit the mesh aperture size and spacing between the mesh cross-members 150 and 152 of the mesh panels 105 that the adjustable panel connector 100 is to interconnect. It should be appreciated that the size of each of the first panel element 102 and the second panel element 104 and the spacing between the first mesh receiving channel 130 and the second mesh receiving channel 133 thereof is dependent on the configuration of the mesh of the mesh panel 105 that the adjustable panel connector 100 is to interconnect.

(31) As shown in FIGS. 6 and 7, in use, the first mesh receiving channel 130 and the second mesh receiving channel 133 of each first panel element 102 and second panel element 104 are used to cooperatively secure the respective first panel element 102 or second panel element 104 of the adjustable panel connector 100 to that mesh panel 105. In use, the adjustable panel connector 100 is firstly configured to the required angle by orientating the first panel element 102 and the second panel element 104 to a desired angle about axis X-X and then inserting the pivot locking rod 112 into the respective connector sleeves 116 of the first panel element 102 and the second panel element 104 to lock in that angle. In FIGS. 6 and 7, the angle between the first panel element 102 and the second panel element 104 has been locked into 180 degrees. The second mesh receiving channel 133 of each of the first panel element 102 and the second panel element 104 is then slotted around the respective edge cross-members 150 of two adjacent mesh panels 105. The next set of mesh cross-members 152 of the mesh panel 105 are then received within the first mesh receiving channel 130 and the locking channel 134 of the locking element 132. Here, each first fastening arrangement 106 is an open configuration, with the locking element 132 in the receiving position (as shown in configuration (A) of FIG. 7). A user then rotates the locking element 132 using the respective handle to the locking position (as shown in configuration (B) of FIG. 7 and the orientation of the locking element 132 in FIG. 6) to engage the locking element 132 around and/or over the received mesh cross-members 152. This secures that section of mesh panel 105 within the first fastening arrangement 106.

(32) A mesh panel 105 can also be attached to the respective first panel element 102 and second panel element 104 using an eccentric joiner 162 and a cooperating stopper 210 connected to the joiner engagement aperture 108 of each of the first panel element 102 and the second panel element 104.

(33) The illustrated joiner engagement aperture 108 comprises a central aperture formed within each of the first panel element 102 and the second panel element 104. As shown in FIGS. 2 and 3, the aperture may include reinforcing body 108A extending from the base of the respective panel element 102, 104. The joiner engagement aperture 108 is configured to receive a connection projection 206A or 206B of a cooperating joining element, for example eccentric joiner 162 illustrated in FIG. 4 or eccentric joiner 162E illustrated in FIG. 4A.

(34) The illustrated eccentric joiner 162 or 162E and mesh stopper 210 or 210E can be used with the illustrated adjustable panel connector 100 to fasten a small portion of a mesh panel to the adjustable panel connector 100.

(35) Firstly referring to the first embodiment illustrated in FIG. 4, the illustrated eccentric joiner 162 comprises generally oval shaped body 205 having two projections 206A and 206B extending perpendicularly from each of the broad faces 207A and 207B of that body 205. The first projection 206A and the second projection 207B extend in opposite directions from the body 205 and are generally parallel and offset (eccentrically aligned) with respect to each other.

(36) Both the first projection 206A and the second projection 206B each include a circumferentially extending flange 208 for securement with the joiner engagement aperture 108 of the each of the first panel element 102 or the second panel element 104, or with the connection aperture 212 of the mesh stopper 210 shown in FIG. 4(b). The flanges 208 comprise one or more frustoconical portions, forming a flared, barbed head located at or near the end of the projections 206A, 206B. Each flange 208 also include a cross shaped split through its center to enable greater resilient compression of those flanges 208 when secured in or through the respective cooperative joiner engagement aperture 108 or 212 of the first panel element 102, the second panel element 104 or stopper 210 respectively. The flanges 208 enable the two parts to snap together, but inhibit subsequent separation of the two parts.

(37) When in use, first projection 206A or the second projection 206B is inserted into the joiner engagement aperture 108 joiner engagement aperture 108 of the first panel element 102 or the second panel element 104. Circumferentially extending flange 208 is designed to extend through that joiner engagement aperture 108 and abut on and be captured at the edge of the opening of the joiner engagement aperture 108.

(38) It should be appreciated that once one of the projections 206A or 206B is received in the joiner engagement aperture 108 of the first panel element 102 or the second panel element 104, the eccentric joiner 162 is able to rotate about that connection. The unused projection 206A/206B is then able to rotate about a circle, relative to the other projection 206B/206A to provide a degree of positional adjustability for that other projection 206B/206A. As will be described below, this provides an advantage when mounting a mesh panel 105 to the first panel element 102 or second panel element 104 of the adjustable panel connector 100, as the free projection can be positioned in alignment with a mesh aperture of the mesh panel 105.

(39) The illustrated stopper 210 (FIG. 4(b)) is a clip button having a generally circular disc having a centrally formed connection aperture 212 which is used to attach the stopper 210 onto either the first projection 206A or the second projection 206B of the eccentric joiner 162. The illustrated stopper 210 is designed to be fixedly fastened onto the either the first projection 206A or the second projection 206B of the eccentric joiner 162, and therefore must be destroyed, for example by cutting, to be removed from that projection 206A or 206B.

(40) As shown in FIGS. 8, 9 and 10, the stopper 210 and the eccentric joiner 162 are used to sandwich and secure a portion of a mesh panel 105 between the body of the eccentric joiner 162 and the stopper 210. The stopper 210 is generally sized to be larger than the length and width of the apertures in the mesh panel 220, so that the mesh panel 105 is unable to be unintentionally removed.

(41) The second embodiment of the eccentric joiner 162E and stopper 210 illustrated in FIG. 4A, has generally the same configuration as the eccentric joiner 162 illustrated in FIG. 4. Again, the eccentric joiner 162E comprises generally oval shaped body 205E having two projections 206E and 206F extending perpendicularly from each of the broad faces 207E and 207F of that body 205E in opposite directions and are generally parallel and offset (eccentrically aligned) with respect to each other. Both the first projection 206E and the second projection 206F each include a circumferentially extending flange 208E for securement with the joiner engagement aperture 108 of the each of the first panel element 102 or the second panel element 104, or with the connection aperture 212E of the mesh stopper 210E shown in FIG. 4A(b).

(42) However, in this embodiment, the flanges 208E comprise directly orientated barbs only extending about 90 on each projection 206E, 206F and located on opposite sides thereof. Each flange 208E and projection 206E, 206F still include a cross shaped split through its center to enable greater resilient compression of those flanges 208E when secured in or through the respective cooperative engagement aperture 108 or 212E of the first panel element 102, the second panel element 104 or stopper 210E respectively. The flanges 208E enable the two parts to snap together, but inhibit subsequent separation of the two parts.

(43) The illustrated stopper 210E (FIG. 4A(a)) is a clip button having a generally circular disc having a centrally formed connection aperture 212E which is used to attach the stopper 210E onto either the first projection 206E or the second projection 206F of the eccentric joiner 162E. However, in this case, the stopper 210E is designed to be releasably attached to the respective first projection 206E or the second projection 206F using a tool 190E (FIG. 4A(d)) the aperture 212E includes locking shoulders 213E configured to seat and lock the flanges 208E of the respective projection 206E, 206F in place. The aperture 212E also include release openings 213F, orientated 90 from each locking shoulder 213E, sized and configured to allow the flanges 208E of the respective projection 206E, 205F to pass through substantially unimpeded. This stopper 210E and flange 208E configuration therefore allows the stopper 210E to be more easily applied and removed through insertion and removal of the flanges 208E through the release openings 213F using locking tool 190 (FIG. 4A(d)). The locking tool 190 is a T shaped tool having three turning arms 192E, an insertion shaft 194E having a tool end 196E having a complementary configuration to the features of the aperture 212E of the stopper 210. It should be appreciated that the configuration of the locking tool 190 can differ, for example include two turning arms or four turning arms and still function as described. The locking tool 190 generally needs to be also pushed towards the stopper 210E to compress the stopper, and then the stopper 210E can be locked in place by rotation of the stopper 210E by 90 to capture the flanges 208E on the respective locking shoulders 213E, and removed by rotation of the stopper 210E by 90 to remove the flanges 208E on the respective locking shoulders 213E.

(44) Again, the stopper 210E and the eccentric joiner 162E are used to sandwich and secure a portion of a mesh panel 105 between the body of the eccentric joiner 162E and the stopper 210E. The stopper 210E is generally sized to be larger than the length and width of the apertures in the mesh panel 220, so that the mesh panel 105 is unable to be unintentionally removed.

(45) Referring firstly to FIGS. 8 and 9, illustrate use of the adjustable panel connector 100, two eccentric joiners 162 and two stoppers 210 to interconnect two adjacent mesh panels 105. In use, the adjustable panel connector 100 is firstly configured to the required angle by orientating the first panel element 102 and the second panel element 104 to a desired angle about axis X-X and then inserting the pivot locking rod 112 into the respective connector sleeves 116 of the first panel element 102 and the second panel element 104 to lock in that angle. In FIGS. 8 and 9, the angle between the first panel element 102 and the second panel element 104 has been locked at 180 degrees. In FIG. 10, the angle between the first panel element 102 and the second panel element 104 has been locked at 90 degrees. Each of the first eccentric joiners 162 is then snap fitted to the respective connection aperture 212 of the first panel element 102 and the second panel element 104. The second projection 206B of the eccentric joiner 162 is then aligned with and inserted through mesh apertures 220 which are proximate the edge cross-members 150 of adjacent mesh panel 220. One or both of the eccentric joiners 162 may be manually rotated if the apertures 220 on the mesh panel 105 do not line up with the second projection 206B. The eccentric nature of the eccentric joiner 162 enables the location of the second projection 206B to translate around an arc, circle or part thereof relative to (and centred about) the first projection 206A through rotation of the eccentric joiner 162 about the first projection 206A. The mesh panel 220 can be pushed into place when a suitable position is reached where the second projection 206B lines up with the apertures 220 of the mesh panel 105. The stopper 210 is snapped into engagement with the second projections 206B to sandwich the respective section of the mesh panel 105 between the respective stopper 210 and eccentric joiner 162.

(46) In the embodiment depicted in the drawings, the stopper 210 connects to the first projection 206A on account of the flared barb like head or flanges 206C, as described above. However, it will be appreciated that the first projection 206A and stopper 210 may be connected with a set screw, grub screw or other fastener.

(47) Each of the first panel element 102 and the second panel element 104 also include two fastening apertures 229 (FIGS. 1 to 3) used to receive a fastener such as a bolt, screw, nail, rivet or similar. As shown in FIGS. 2 and 3, each fastening aperture 229 includes strengthening body 229A formed integrally on the underside of the respective first panel element 102 and the second panel element 104. As best shown in FIG. 11, the fastening apertures 229 can be used to mount one of the first panel element 102 or the second panel element 104 to a mounting body, such as kick plate 230 by fastening that panel element, in this case the first panel element 102, to that body using a fastener, in this case bolts 232. The bolts 232 are received through the fastening apertures 229 of the first panel element 102 and fastened to the kick plate 230. The second panel element 104 can be connected to the adjacent mesh panel 105 using either the first fastening arrangement 106 (as illustrated in FIG. 11) or using an eccentric joiner 162, as described above. Again, the adjustable panel connector 100 can be configured to the required angle by orientating the first panel element 102 and the second panel element 104 to a desired angle about axis X-X and then inserting the pivot locking rod 112 into the respective connector sleeves 116 of the first panel element 102 and the second panel element 104 to lock in that angle.

(48) FIGS. 12 to 16 illustrate a second embodiment of an adjustable panel connector 300 developed by the Applicant which can be used to interconnect mesh panels 105 that form part of a barricade, guarding barricade and/or guarding system or assembly.

(49) The illustrated adjustable panel connector 300 generally comprises a first elongate rectangular panel element 302 and a second elongate rectangular panel element 304 interconnected along and about a connection axis Y-Y. The first panel element 102 and the second panel element 104 are interconnected using a connection arrangement 310 configured to lock the first panel element 102 at a selected angle relative to the second panel element 104 about the axis Y-Y.

(50) Each of the first panel element 102 and the second panel element 104 include two cavities or channels 311 that extend in generally opposing directions relative to one another. The panel connector 300 is of an undefined length, and in which the two cavities 311 span said undefined length. The cavities 311 are formed between two spaced apart elongate members 317A, 317B, and 317C, 317D of the first elongate rectangular panel element 302 and the second elongate rectangular panel element 304.

(51) The cavities 311 are configured to receive and capture the edges of mesh panels 105.

(52) As illustrated in FIG. 14, in some embodiments the cavities 311 may include a series of angled teeth 330 therein, which are oriented at an angle in order to grab and secure an edge of the mesh panel 105 therein.

(53) As illustrated in FIGS. 15 and 16, in other embodiments, each of the panel elements 102 and 104 may also include openings 335 (FIGS. 15 and 16) configured to receive a ribbed or ridged fastening pin 336 (FIG. 16). When an edge portion of a mesh panel 305 is received in channels 311, the fastening pin 336 can be inserted into the openings 335, through an aligned aperture of the mesh panel 105 to fasten that edge portion between the elongate members 317A, 317B, 317C and 317D of the first elongate rectangular panel element 302 and the second elongate rectangular panel element 304. In some embodiments, the fastening pin 336 can be used to compress or clamp the elongate members 317A, 317B, and 317C, 317D together. In the illustrated embodiments, the openings 335 are arranged in a V-formation to allow for the selection of the best aligned opening 335 with each respective aperture of the mesh panel 305.

(54) The embodiment of the adjustable panel connector 300 shown in FIGS. 15 and 16 also include an aperture 336 configured to receive the first projection 206A or the second projection 207B of an illustrated eccentric joiner 162 or 162E. The eccentric joiner can be used to in conjunction with a mesh stopper 210 or 210E to fasten a small portion of a mesh panel 305 to the adjustable panel connector 100, or alternatively mount a fastening clip or clamps, for example the fastening clips or clamps described in the Applicant's international patent application PCT/AU2011/001165 to mount the mesh panel and/or adjustable panel connector 300 to a mounting point such as a rail, post or the like.

(55) Similar to the first embodiment, the illustrated pivot connection arrangement 310 comprises a hinge assembly having a plurality of pivot locking rods 312 each of which are received in a series of connector sleeves 316 which form part of each of the first panel element 302 and the second panel element 304.

(56) Each pivot locking rod 312 comprises an elongate connection rod including a plurality of longitudinal ribs 314 (FIG. 13) extending around the circumference of the rod. Each of the first panel element 302 and the second panel element 304 include a series of spaced apart connection sections 315 which include two spaced apart connector sleeves 316 aligned with and extending along the axis Y-Y. The pivot locking rod 312 is releasably received within a respective set of connector sleeves 316 of a connection section 315. The respective connector sleeves 316 of the connection sections 315 of the first panel element 102 and the second panel element 104 interlace about and along the axis Y-Y. Each connector sleeve 316 includes an internal channel 318 (FIG. 14) having a complementary fluted configuration to the ribbed pivot locking rod 312. This complementary shape forms an interference fit between the pivot locking rod 312 and the connector sleeves 316, when the pivot locking rod 312 is received within the connector sleeves 316. This fit prevents rotation of the connector sleeves 316 around the pivot locking rod 312, thereby locking the position of the first panel element 302 and the second panel element 304 at a fixed angle relative to the axis Y-Y.

(57) The angle between the first panel element 302 and the second panel element 304 can therefore be adjusted to match the required angle between two adjoining mesh panels and then locked into place by inserting the pivot locking rod 312 into the respective connector sleeves 316 of each connection section 315 of the first panel element 302 and the second panel element 304.

(58) A cap 340 (FIG. 16) may be provided that fastens over an end of the adjustable panel connector 300 and/or over the end of the mesh panel 305 so as to enclose the side profiled openings of the cavities 311. The cap 340 may also include a series of openings 342 configured to receive a ribbed or ridged fastening pin 336 for securement to the end of the adjustable panel connector 300 or through an aperture of the mesh panel 305. Again, the openings 342 may be arranged in a V-formation to allow for the selection of the best aligned opening 342 with each respective aperture of the mesh panel 305. However, it should be appreciated that the arrangement of openings 342 could have any suitable, for example, circular, T-shaped, U-shaped, X-shaped, Y-shaped or the like.

(59) It should be appreciated that the illustrated adjustable panel connector 100 can be used as part of guarding systems on conveyors, actuators, rotating machinery and many more applications.
