Fencing

This invention concerns a fencing corner extension arrangement, and also a fencing extension assembly.

Security fencing is widely used in a range of applications. Such fencing generally comprises a plurality of spaced posts, with fencing panels, wire or other material extending between the posts. It is often required to provide cranked upper ends to such fencing, and such cranked ends may be inclined outwardly to prevent unauthorised entry, or perhaps cranked inwardly to prevent escape. One such application is for containing animals where the cranked upper ends will generally extend inwardly.

Difficulties can however be encountered in providing cranked upper ends at corners between lengths of fencing, which corners need not necessarily be at right angles. This may require a bespoke arrangement, or in some instances a rather unsatisfactory arrangement may be used, in view of the difficulties encountered.

In some instances it is desired to retrofit an overhang on a fence or perhaps other barrier arrangement. Again difficulties can be encountered with this, and particularly at comers.

According to a first aspect of the invention there is provided a fencing corner extension arrangement, the arrangement including a mounting part mountable to an upper end of a fence post or other fixture, and a support part, the support part being mountable to the mounting part when the mounting part is mounted on a fence post or other fixture so as to extend upwardly therefrom at an inclination to the fence post or other fixture, the mounting part and support being configured such that they can be mounted together at a required relative rotational alignment.

The mounting part and support part may be configured such that they can be joined together and then moved to a required relative rotational alignment, and then mounted together in the required rotational alignment.

The mounting part may comprise a first planar part with a spaced pair of mounting holes with which the support part is engageable when mounted together with the mounting part.

A one of the mounting part mounting holes may be elongate, may be arcuate, and may be arcuate about an axis defined by the other mounting part mounting hole.

The support part may comprise a corresponding pair of mounting holes, such that the mounting part and support part can be mounted together by fastening means extending through the respective mounting holes in the mounting part and support part.

The mounting holes in the support part may have the same spacing as the mounting holes in the mounting part. The mounting holes in the support part may be circular and may be tapped.

The support part may include a mounting portion which includes the mounting holes, and an elongate support portion extending therefrom. The mounting portion may comprise a first planar part in which the support part mounting holes are provided and a second planar part may be provided extending perpendicularly to the first planar part.

The elongate support portion may be in the form of a tube, which may be of square cross section, extending from the mounting portion inclined thereto. Openings or other formations may be provided on the elongate support portion to facilitate mounting of line means or other barrier parts thereto.

The mounting part may comprise a second planar part extending perpendicularly to the first planar part. The second planar part may be mountable to a fence post or other fixture, and one or more mounting holes may be provided in the second planar part.

The mounting part may also include a third planar part extending from the first planar part, spaced from and parallel to the second planar part, such that a fence post or other fixture can locate between the second and third planar parts. The third planar part may extend for a shorter distance from the first planar part than the second planar part does.

The straight extension mounting part may include a first planar part locatable on top of a fence post or other fixture, a second planar part extending perpendicularly to the first planar part, mountable to a fence post or other fixture.

The straight extension mounting part includes a third planar part extending from the first planar part, spaced from and parallel to the second planar part, such that a fence post or other fixture can locate between the second and third planar parts. The third planar part may extend for a shorter distance from the first planar part than the second planar part does.

The support part may extend at an inclination of between 20 and 70° to the vertical direction when mounted to a fence post or other fixture, and more particularly may extend at an inclination of between 28 and 62°.

According to a further aspect of the invention there is provided a fencing extension assembly, the assembly including one or more fencing corner extension arrangements according to any of the preceding ten paragraphs, and a plurality of fencing straight extension arrangements, the fencing straight extension arrangements comprising a mounting part mountable to an upper end of a fence post or other fixture, and a support part fixedly extending from the support part inclined upwardly in use.

The support part of the fencing corner extension arrangement may be longer than the support part of the fencing straight extension arrangement.

The support part of the fencing corner extension arrangement may be at a greater inclination to the vertical than the support part of the fencing straight extension arrangement.

The drawings show extension arrangements which can be fitted retrospectively onto a fence to provide an inwards overhang as shown for instance in Fig. 11, or an outwards overhang as shown for instance in Fig. 13.

Figs. 1 to 7 show a fencing corner extension arrangement 10 mountable to the top of a fence post 12 as shown for instance in Figs. 12 and

15. The arrangement 10 includes a mounting part 14 in the form of an inverted L shape plate 16 with a base 18 which has a first circular mounting hole 20 spaced from the stem 22, of the L and a second mounting hole in the form of an arcuate slot 24 towards the stem, with the arc having the first mounting hole 20 as its axis. The stem 22 is longer than the base 18 and includes two spaced circular mounting holes 26.

The arrangement 10 also includes a support part 28 which is in the form of a length of square cross section tube 30 with an L shaped mounting portion 32 at one end. The support part mounting portion 32 includes an L shaped bracket 34 which is mountable on a lower end in use of the tube 30 at an inclination for instance of 35° to the longitudinal direction of the tube 30. The bracket 34 is formed from a folded single piece of metal such as steel, and welded to the tube 30. The base of the mounting portion 32 has two tapped circular mounting holes 36 at the same spacing as the mounting holes 20, 24 in the mounting part 14.

The support part 28 can be mounted to the mounting part 14 by bolts 38 extending through the respective mounting holes 20, 24, 36, and a required relative rotational alignment chosen. Once this alignment has been reached the bolts 38 can be tightened to maintain this alignment. The fencing corner extension arrangement 10 can then be mounted to the top of a fence post 12 using the mounting holes 26 on the stem 22 of the mounting part 14 to provide an arrangement for instance as shown in Fig. 12. Figs. 2 and 3 illustrate different relative rotational orientations between the mounting part 14 and support part 28. Figs. 9 to 12 illustrate an inwardly inclined overhang where the support part 28 is inclined into the corner. Such an arrangement can be used for instance for retaining animals in a required location.

In a fencing extension assembly the corner extension arrangement 10 can be used with a plurality of straight extension arrangements 40. Fig. 8 illustrates a corresponding straight extension arrangement 40 and a corner extension arrangement 10 adjacent each other and at the same scale. In the straight extension arrangement 40, separate mounting parts and support parts are not required. Here a support section 42 extends into a mounting section 44, again with a pair of mounting holes for mounting on a fence post 12 or other fixture. The mounting section 44 is formed from a folded single piece of metal such as steel, and welded to the support section 42.

The inclination of the support section 42 to the mounting section 44 is a little greater in the straight section arrangement 40, and here is approximately 45°. Also the support section 42 is shorter than the support part 28 of the corner extension arrangement 10, and extends for only around 80% of the length of the corner section support part 28. As can be seen for instance in Fig. 9, in view of the inclination relative to the fence of the corner section arrangement 10 in a corner, the support part 28 requires to extend for a greater length than the support section 42, and as can be seen from Fig. 8 the overall overhang height is substantially maintained.

As noted Figs. 9 to 12 show an inwards overhang, whilst Figs. 13 to 16 show an external overhang. In these instances barbed wire 46 is illustrated extending between the support sections 42 and support parts 28. Threaded inserts 48 or other mounting formations as shown for instance in Figs. 1 and 6, may be provided for mounting the barbed wire 46 or other wire or similar, to the support sections 42 and support parts 28. Fig. 17 illustrates an arrangement where the overhang includes a mesh panel 50 as opposed to barbed wire. It is to be realised that a range of materials can extend in the overhang and in the fence itself.

Fig. 18 shows a modified fencing corner extension arrangement 11 which is similar to the arrangement shown in Fig. 1 except that a lip 25 is provided extending from the base 18 parallel to and spaced from the stem 22, such that a fence post 12 can fit therebetween.

Figs. 19 and 20 show a modified straight extension arrangement 41 which is similar to the arrangement 40 except that a lip 43 is again provided on the mounting section 44, such that the upper end of a fence post 12 can fit between the stem of the mounting section 44 and the lip 43.

The lips help to prevent the support parts being bent.

There is thus described fence extension arrangements and a fence extension assembly which readily permits retro fitting on an existing fence. Furthermore common components can be used and different angled corners can be accommodated, whether with an inwards or outwards overhang.

A wide range of modifications may be made without departing from the scope of the invention. The above described assemblies can be formed of steel as indicated, with different component parts welded to each other. Alternatively the assemblies could be formed of aluminium, with different component parts mounted together by TIG welding.

As indicated a wide range of fencing or other barrier arrangements can be used. Different mounting means may be provided between the respective components. Obviously different angles and/or lengths of overhang can be used as required.

Whilst endeavouring in the foregoing specification to draw attention to those features of the invention believed to be of particular importance it should be understood that the Applicant claims protection in respect of any patentable feature or combination of features hereinbefore referred to and/or shown in the drawings whether or not particular emphasis has been placed thereon.
