Patents Act 1990 COMPLETE SPECIFICATION STANDARD PATENT Fence Panels and Method of Fencing This invention relates to fence panels and to methods of erecting fences from panels.

S-Fence panels of the invention may be successively erected and attached to form a 10 continuous fence.

Panels according to the present invention are characterised by including a first frame member formed to receive a supporting picket, and a second frame member formed so as to be engageable for support by the first frame member of a similar panel.

e.

The pole or picket is preferably adapted to be driven into the ground after being received by the first frame member.

Preferably the panels are completed by top and bottom rails, and the panel wall may 20 be profiled steel sheet such as roofing sheet.

In a particular form the invention provides a fencing panel which enables the rapid erection of fences which have many of the characteristics of a paling fence, particularly the repetitive pattern of the pales which make up the fence, with a minimum of tools or special equipment. This is achieved in a panel which includes a frame having rails which are provided with formations which locate and maintain the pales in a desired pattern.

The invention will now be described, by way of example only, with reference to a presently contemplated embodiment shown in the accompanying drawings, in which: Fig. 1 shows in side elevation a panel according to a first embodiment of the invention; Fig. 2 is a plan view of the panel of Fig. 1; Fig. 3 is a sectional plan view taken on the line 3 3 in Fig. 1; Fig. 4 is a fragmentary illustration of a first side post; Fig. 5 is a fragmentary illustration of a second side post; Fig. 6 is a fragmentary illustration of a picket; Fig 7 is a side elevation of a fence panel according to a second embodiment of oo e 10 the invention; V Fig 8 is a section taken on the line 8-8 in Fig 7; Fig 9 is an isometric view of a top or bottom rail, and Fig 10 is an isometric view of a centre rail.

15 The panel illustrated in Figs. 1 to 3 consists of a frame comprising side post members 110 and 111, upper and lower rails 112, and a panel wall 113. The wall 113, which in this embodiment consists of a sheet of roll-formed coated steel profile but may be of ~any suitable material or combination of materials, is held in place between side flanges 114 of the rails 112, which are in turn fixed to the post 110 by metal screws or 20 other fixing devices 120 passing through flanges 115 which extend inwardly from the post 110 to embrace the edge of the wall 113.

The post members 111 are in the form of channels, having opposed edge flanges 117 which receive for fixing between them the ends of the rails 112, and a body which is shaped to form a pocket 118.

The post members 110 and 111, which may be formed from galvanised sheet by stamping and roll-forming, are shown in detail in Figs. 4 and 5 respectively. It will be observed that the post 110 has formed in its face downwardly disposed tongues 121 which may be pressed outwardly so they are disposed outwardly and obliquely downwardly of the face of the post, while the post 111 has in its face correspondingly spaced apertures 122.

As shown in the drawings, each post member 111 is attached to the right hand end (as viewed in the drawings) of the panel by means of the flanges 117, by means of screws or other fastening devices driven through the flanges 117 into the side flanges 114 of the rails.

The pocket 118 formed by the post 111 is dimensioned to receive a picket 116 (Fig. 6) having four obliquely disposed flanges which locate the internal corners of the post. In S:.i this embodiment the picket is fabricated by a pair of channel sections 123 and 124 10 having outwardly oblique flanges 125, the channel sections being fixed back to back, Sfor example by welding. The pickets 116 may be formed in other ways, for example by extrusion as a single piece. Although not shown in the drawings, the pickets 116 may be tapered at their lower end to facilitate their being driven into the ground. Such pickets support the fence and enable its assembly by the methods described below.

*i With the arrangement thus described, a fence may quickly and easily be erected by locating a first panel at the fence line and driving a picket 116 down through the pocket 118 of the post 111 to fix the panel in place. A second panel may then be engaged with the first as described above, by engaging the tongues 121 of the post 110 20 of the next panel with the apertures 122 of the post ll of the first panel. A further picket 116 may then be driven down the pocket 118 of the second panel's post I 11.

The length of the line of fence is completed by repeating this process. A fence may in this way quickly be erected without special tools, indeed with only a string line, spirit level and a picket driver.

The pickets 116 are preferably driven fully into the posts 110, whereupon if desired a cap (not shown) may be placed over the otherwise open upper end of each post.

It will be understood that where the line of the fence extends across sloping ground, the slope may be accommodated by a providing a partial, rather than complete, vertical overlap of successive panels, by choosing the points of engagement of the respective tongues and apertures 121 and 122.

As mentioned above, the panel wall 113 may take any suitable form. In the embodiment of the invention illustrated in Figs 1 to 3, the panel is in the form of a roll-formed steel sheet. In the embodiment of the invention illustrated in Figs 7 the panel is formed from overlapping wooden pales.

The panel illustrated In Figs 7 to 10 comprises a metal frame having side posts 110 and 111 constructed in the same manner as described in relation to Figs 1 to 6. In this case, however, the panel wall consists of a number of overlapped wooden pales 316, 10 and the panel is completed by a pair of top and bottom rails 312 and a pair of opposed V 6% centre rails 314 and 315.

.:oooi The pales 316 are held in place in the panel by the rails 312, 314 and 315. The upper ends of the pales are located in a channel formed by the upper rail 312, and lower ends 15 are similarly located in a channel formed by the lower rail. The pales are furthermore "held between the opposed centre rails 314 and 315. Figs 11 and 12 show in detail the relevant features of these rails. (It will be understood that while only the bottom rail 312 is illustrated here, the top rail can be identical to it). Each of the rails may be formed in galvanised sheet steel by stamping and roll-forming.

The bottom rail 311 consists of a bottom web 319 with a pair of side flanges 320.

Each of the side flanges has an in-turned edge flange 321, provided with spaced recesses 322 for the reception of a pale 316. It will be observed that the recesses 322 of the opposed edge flanges 321 are staggered to accommodate, and indeed define, the regular overlapping pattern of the pales 316.

The centre rails 314 and 315 have a vertical web 326 and upper and lower edge flanges 327, again provided with spaced recesses 328 for the reception of the pales 316. Only the centre rail 314 is illustrated, as it will be understood that the rail 315 is similar, with a relatively staggered location of the recesses 328 so as to repeat the pattern of recesses established by the rails 3 10 and 3 11.

A fence is erected from panels of the kind illustrated in Figs. 7 to 10 in the same manner as that described in relation to Figs. 1 to 6.

The pattern of palings can of course be varied from that shown. Other changes to the configuration of the elements of the panel, which has been illustrated by way of example only, may be made without departing from the scope of the invention. In particular, panels having panel walls of different kinds, for example the steel and paling walls described above, can be alternated in a continuous line of fence.

oo..oi 10 It will also be understood that the invention may be embodied in ways other than that illustrated. For example, where a temporary fence is to be erected such as for event or safety fencing, free-standing poles may be employed instead of pickets driven into the ground, and alternative formations may be adopted for the interengagement of the successive panels.
