Description

BRIEF DESCRIPTION OF THE DRAWINGS

(1) The invention is further described by way of examples with reference to the accompanying drawings in which:

(2) FIG. 1 is a perspective view from one side of a fence panel according to the invention,

(3) FIG. 2 illustrates a modified form of the fence panel shown in FIG. 1, and

(4) FIGS. 3A-3F are respective end views of a fence panel according to the invention showing various configurations of deterrent components.

DESCRIPTION OF PREFERRED EMBODIMENTS

(5) FIG. 1 of the accompanying drawings illustrates a fence panel 10 according to one form of the invention.

(6) The panel 10 includes a sheet 12 of mesh material and a plurality of deterrent components 14 which are fixed to the sheet 12 at spaced apart intervals.

(7) The sheet 12 has a first edge 18 which in use extends horizontally and is uppermost, an opposing lower second edge 20, and third and fourth opposing edges 22 and 24 respectively which in use extend substantially vertically.

(8) The sheet is rectangular in outline. In this specification “rectangular” includes “square”.

(9) At the third and fourth edges 22, 24 the sheet 12 has flanges 28 which enable the sheet to be fixed between spaced apart fence posts (not shown) which are erected using appropriate techniques to follow a barrier line. The flanges 28 are substantially at a right angle to a plane 32 (see FIG. 3A) in which the mesh sheet lies. The flanges 28 are bolted or fixed with appropriate fasteners 30 to the posts and the panel is then positioned between an adjacent pair of posts. The sheet 12 is formed from a first array of horizontally extending spaced apart wire rods 34 and a vertically extending array of spaced apart wire rods 36. The spacing between adjacent pairs of rods 34 is substantially less than the spacing between adjacent pairs of rods 36. The two arrays overlap one another and the rods 34 are welded to the rods 36 at respective points of contact.

(10) Referring in addition to FIGS. 3A to 3F the sheet 12 is formed with a number of reinforcing formations 40. Each formation 40 is in the form of a channel which extends from the third edge 22 to the fourth edge 24, i.e. each channel formation is substantially horizontal, in use. Each channel has a V-shape and although this is preferred it is exemplary and non-limiting.

(11) The deterrent components 14 comprise elongate metallic strips 44 which are formed with sharp protruding spikes 46. The strips 44 are fixed by means of fasteners 50, e.g. rivets, to successive sides 54 of the reinforcing formations 40. FIGS. 3A to 3F show different configurations of the deterrent components 14.

(12) FIGS. 3A and 3C show that on one side of the sheet the spikes 46 project generally upwardly while on an opposing side of the mesh sheet the spikes project laterally and generally downwardly.

(13) FIG. 3B shows an arrangement wherein the spikes 46 project generally upwardly on one side of the sheet 12. In FIG. 3D the spikes 46 project generally downwardly, on both sides of the sheet 12. In FIG. 3E on one side of the sheet 12, one set of spikes 46 projects generally upwardly and, a second set of spikes 46 projects generally downwardly. FIG. 3F is similar to FIG. 3D except that the spikes 46 project generally upwardly and not downwardly. Although these are preferred configurations, they are nonetheless exemplary and non-limiting.

(14) If required vertically extending metallic strips 44 with protruding spikes 46 can be fixed to the posts to which the sheet are fixed. The spikes 46 on the posts provide an additional degree of deterrence.

(15) When the mesh sheet 12 is formed, and prior to the reinforcing formations 40 being fashioned, the mesh sheet 12 is reinforced by means of parallel, spaced apart flat bars 56 which are welded to the mesh and which are positioned between successive adjacent pairs of vertically extending rods 36.

(16) Given the significant barrier presented by the deterrent components 14 and the strong physical construction of the mesh sheet, stiffened by means of the reinforcing formations 40 and by means of the lengths of flat bar 56 the fence panel, once erected, offers substantial resistance to penetration. It is also difficult to climb over the fence. Under-digs in the ground, over which the fence panel is erected, can include mesh sections optionally embedded in concrete, to further enhance the deterrent effect of the erected barrier.

(17) FIG. 2 shows a fence panel 10A which in many respects is similar to the fence panel 10. However the mesh section 12A includes vertically extending rods 36A which are substantially closer to one another that what is the case for the mesh sheet 12. The sheet is reinforced by means of lengths of flat bar 56A which are present in a higher density than in the arrangement shown in FIG. 1. Thus, overall, the fence panel 10A is more robust than the panel 10.
