TECHNICAL FIELD

Disclosed herein is a system for securing items to a post. The post comprises at least one elongate flange which is adapted for having at least one device mounted thereto. A portion of a side of the flange can be deformed relative to a remainder of the side to facilitate mounting of the device thereto. When the device is mounted to the post it may be configured to secure, for example, at least one strand (e.g. a wire strand) to the post. The post may thus find particular application in fencing to secure one or more wire strands to a fence post, although the post may be employed in applications such as demarcation, signage, retention, barricades etc. The term "strand" as employed herein is to be broadly interpreted to include various elongate components that can be secured to a post.

BACKGROUND ART

Posts for use in applications such as fencing, demarcation, signage etc are known. Such posts are usually formed from steel, though in some applications it is known to mould posts from a plastic material (e.g. for use in electric fencing).

Steel fence posts have been known for many years that are roll-formed to have a Y-shaped or T-shaped profile (i.e. in end view). The post may take the form of a picket and, in this case, may be provided (e.g. cut) with a pointed end to facilitate post driving into the earth.

Such steel fence posts are usually provided with a series of spaced holes in a flange thereof (i.e. in the so-called "stalk" or "stem" of the post) to enable strands of fencing wire to be secured to the post, usually by tying each wire strand to the post with a separate short length of wire tie threaded through an individual hole, or by employing a wire "clip". However, the wire can also be directly threaded through such holes. These holes are typically punched into an already roll-formed post in a separate step.

In addition (or as an alternative) to the series of holes, the posts can be provided with a series of spaced passages that are usually cut or machined to project right into the stalk from a distal edge thereof. These passages enable a strand of fencing wire to be moved into and retained in the passage, thereby securing the wire directly to the post. An additional latch can be mounted to the post in the vicinity of the passage that allows the fencing wire strand to be moved therepast, and that retains the wire once located in the passage. Usually this latch is factory-fitted to the post in a separate stage.

Again, it has been observed that these passages are typically cut or machined into an already roll-formed post in a separate step, adding additional manufacturing complexity and cost. In addition, the passages and the attachment of the latches can compromise the strength, integrity, corrosion resistance, etc of the stalk and thus of the entire post in use.

The existing systems for attaching wire to a fence post can also require a high degree of manual labour, and some of the ties employed also require special tools and the services of a skilled fencer.

WO 2011/020165, to the present applicant, discloses a post mounting system and device in which the device is designed to secure to the post immediately upon assuming its desired location therealong. The post has a series of undulations that prevent the device from sliding along the post, thus maintaining its position on the post.

GB 2286839 discloses a lug on a clip that engages with a hole located in a flange of a post. The lug passes through the hole to mount the clip to the post.

The above references to the background art do not constitute an admission that the art forms a part of the common general knowledge of a person of ordinary skill in the art. The above references are also not intended to limit the application of the system, post, device and method disclosed herein.

SUMMARY OF THE DISCLOSURE

In a first aspect there is disclosed a system for securing at least one strand to a post. The post is adapted for having at least one device mounted thereto. The device can comprise an element that is able to engage with the post.

The post can be of a type that comprises at least one elongate flange, for example, that projects out from a longitudinal axis of the post. The post may have up to three (or more) elongate flanges and may take the form of a Y- or T-post. The flange to which the device is mounted may comprise a stalk or stem of the Y- or T-post (although other flanges of the post may instead be employed). Further, the post may take the form of a picket.

In accordance with the first aspect a portion of a side of the flange of the post can be deformed relative to a remainder of the side to facilitate mounting of the device thereto. In this regard, the deformed portion can be configured to correspond to a distal end of the element, whereby the distal end is able to nest within the deformed portion when the device is mounted to the post.

The configuring of the post to a distal end of the element can provide a simple device-to-post mounting procedure, and the resultant post-device system can also be simpler, cost effective and expedient. The mounting procedure is also simplified because the distal end of the element is able to nest within the deformed portion. This also allows for the device to be configured to detach from the post once a certain (e.g. extreme or threshold) weight or loading is reached. This can prevent post or fence line damage, etc.

In contrast to both WO 201 1/020165 and GB 2286839, the distal end of the device element of the first aspect may be considered as nesting within the deformed portion of the post. The undulations along the post disclosed in WO 2011/020165 are merely provided to prevent the device from sliding along the post. Similarly, the distal end of the lug disclosed in GB 2286839 passes through the hole in the post, and does not nest within the hole.

Further, the deforming of the side of the flange (as opposed to cutting or machining into the flange) means that flange strength, integrity, corrosion resistance, etc need not be compromised. In addition, many more device mounting points can be provided at the flange, without compromising strength, integrity, corrosion resistance, etc, as compared to cut/machined flanges.

In addition, in at least some embodiments, the deforming of the side of the flange can be incorporated into the post forming procedure, whereby separate processing steps can be avoided.

Further, the deforming of the side of the flange (e.g. at a lower portion thereof) can increase the in-ground holding capacity of the post (i.e. non-vertical surfaces and, conceivably, a greater surface area of the flange can be exposed to the earth). In one embodiment, the deformed portion of the post may be configured to closely correspond in shape to the distal end such that the nesting of the distal end in the deformed portion comprises a snug receipt. Such snug receipt should not be interpreted to necessarily imply a "one-for-one" correspondence between the distal end and the deformed portion. For example, if the distal end has a square or rectangular profile, and the deformed portion is circular, the nesting may be such that corners of the distal end abut or sit closely adjacent to an edge of the deformed portion, whereby movement of the distal end in the deformed portion is, nevertheless, resisted.

In any case, such nesting can provide for an increased level of securement of the device to the post, whereby the device is better able to resist removal from the post and movement up or down the post. The level of securement may be such that the wire strand is able to bear weight, which is able to be transmitted via the device to the post, to be supported at the post.

Such a system may also reduce the degree of manual labour in securing one or more strands to the post. In this regard, the device may be simply and rapidly mounted to the post by the user (i.e. in the field). For example, the device may be pressed, pushed or otherwise urged into place manually or by a tool (such as a hammer, or a manual-, pneumatic-, gas-, electric-, etc -type gun). The device may simply be laterally slidable into place.

The system may also eliminate the numerous ties currently employed in fencing, as well as reducing the number of special tools required, whilst also eliminating the services of a skilled user (e.g. fencer).

In one embodiment, the deformed portion of the post may comprise at least one indentation in the flange of the post. The indentation may be formed in the post such that part of the post material is removed, or such that the post material is displaced to form an indentation on one side of the flange, and a corresponding protrusion on the other side. Alternatively, the deformed portion may comprise at least one hole through the flange of the post. In either case the deformed portion may be preconfigured (e.g. preformed) so as to correspond to the distal end of the element (e.g. to closely match it whereby, for example, if the distal end is circular, the deformed portion may be correspondingly circular). In this regard, when the deformed portion comprises a hole, the hole is different to existing fence post holes, in that it is adapted and preconfigured to be suitable to and for the device. The deformed portion may be formed in any suitable shape, such as circular, a vertically or horizontally elongate slot, rectangular, obround, rounded rectangular, triangular, ellipse, a passage, etc. The deformed surface portion may include one, two or multiple indentations or apertures, or a combination thereof.

In one embodiment, the deformed portion of the post may comprise a series of indentations on one or each side of the flange for a length thereof. Alternatively or additionally, the deformed portion may comprise a series of holes through and along the length of the flange. For example, the series of indentations or holes may be formed in the flange such that they are generally aligned along the flange. In the case of indentations, the indented direction of adjacent indentations may alternate along the length of the flange.

In one embodiment, for mounting a given device, two indentations may be provided in the flange of the post. The indented direction of one of the indentations may be opposed to and offset from the indented direction of the other of the indentations. Alternatively or additionally, when mounting a given device, two adjacent holes may be provided in the flange. The employment of two indentations or holes can increase the degree of securement of the device to the post in use.

In one embodiment, the post may comprise a number of discrete deformations spaced out along its length. Each deformation can enable mounting to the post of a respective one of a number of devices. When the devices are each mounted at their respective deformations to thereby be spaced out along the post, the spacing can be such as to correspond to the spacing of horizontal strands in a grid of the strands. Thus, respective strands can be secured to respective devices, whereby the grid can be secured to the post.

In this embodiment, the term "grid" is intended to include a wire mesh, although the terminology mesh is also employed herein.

Such a post allows a wire grid or mesh of having known or pre-existing spacings to be quickly and easily secured to a post. In other words, the post is preconfigured or pre-adapted to the wire grid or mesh. One such post may have a number of respective deformations along its length so that it can have a number of differently spaced wire grids or meshes secured thereto.

In one embodiment, discrete deformation(s) may be provided for each corresponding strand in the grid or mesh. A device may also be provided for a respective one of each of the horizontal strands in the grid or mesh to enable its securement to the post.

In one embodiment, the post may be of a type that comprises at least one elongate flange (e.g. a Y- or a T-post). The discrete deformations may then be spaced out along the length of this flange. For example, each discrete deformation may comprise at least one indentation in the flange of the post. Alternatively or additionally, each discrete deformation may comprise at least one hole through the flange of the post.

In the system a plurality of devices may be provided for (e.g. bundled with) each post, each for securing a respective strand to the post. In this way, multiple strands may then be secured with respect to a single post (e.g. for fencing applications).

In a second aspect there is disclosed a post that is adapted for having at least one device mounted thereto. The device can comprise an element that is able to engage with the post.

The post can be of a type that comprises at least one elongate flange, for example, that projects out from a longitudinal axis of the post. The post may have up to three (or more) elongate flanges and may take the form of a Y- or T-post. The flange to which the device is mounted may comprise a stalk or stem of the Y- or T-post (although other flanges of the post may instead be employed). Further, the post may take the form of a picket.

In accordance with the second aspect a portion of a side of the flange of the post can be deformed to comprise at least one indentation to facilitate mounting of the device thereto. In this regard, the indentation can be configured to correspond to a distal end of the element, whereby the distal end is able to nest within the indentation when the device is mounted to the post.

The configuring of the post to a distal end of the element can provide a simple device-to-post mounting procedure, and the resultant post-device system can also be simpler, cost effective and expedient. The mounting procedure is also simplified because the distal end of the element is able to nest within the indentation. This also allows for the device to be configured to detach from the post once a certain (e.g. extreme or threshold) weight or loading is reached. This can prevent post or fence line damage, etc.

In contrast to WO 2011/020165, the distal end of the device element of the second aspect may be considered as nesting within the deformed portion of the post, as opposed to the undulations disclosed in WO 2011/020165 preventing the device from sliding along the post. In contrast to GB 2286839, the post of the second aspect discloses an indentation, as opposed to a hole.

Further, the deforming of the side of the flange to form an indentation (as opposed to cutting or machining into the flange) means that flange strength, integrity, corrosion resistance, etc need not be compromised. In addition, many more device mounting points can be provided at the flange, without compromising strength, integrity, corrosion resistance, etc, as compared to cut/machined flanges.

In one embodiment, the indentation is formed such that one side of the flange comprises an indentation therein, and the other side of the flange comprises a protrusion corresponding to the indentation (i.e. no material is removed from the flange of the post).

The post, and the deformed portions of the post, may be otherwise as defined in the first aspect.

In a third aspect there is disclosed a device for use in a system according to the first aspect or for attachment to a post according to the aspect. The device of the third aspect comprises a body. The device of the third aspect further comprises projections that extend from the body to define a recess between the projections. The recess is configured to receive a part of the post therein. When attaching the device to a post, the projections can be located adjacent to the indentation of the post.

The device of the third aspect further comprises an element that has a distal end that is configured to nest within the indentation of the post when the device is mounted to the post.

In one embodiment, the element may comprise a fixed or movable part of the device. When the element is movable, it may be moved into the nesting position once the device has been suitably located on the post flange. When the element is fixed, the element and/or a remainder of the device may deform or deflect to enable the device to be suitably located on the post flange, whereupon the distal end is then able to nest within the indentation.

The device may be employed to secure one or a number of strands to the post.

The device may alternatively be adapted for securing other components to the post, such as barriers, signage, etc.

In a fourth aspect there is disclosed a method for securing at least one strand to a post according to the second aspect. The method comprises mounting to a given location along the post a device according to the third aspect. The device is mounted so that the distal end is able to nest within the indentation of the post. The method also comprises securing at least one strand with respect to a given device.

Again, such a method can reduce the degree of manual and skilled labour, and the need for specialised tools, when securing strands to a post, in that the strand(s) can be easily and desirably located and the device simply and rapidly fitted by the user, all whilst out in the field.

In the method at least one strand may be secured with respect to the device before or after the device has been mounted to the post.

In the method a plurality of devices may be mounted to the post. Each device may be mounted at a discrete location along the flange, spaced from each other device. Each device may then secure at least one respective strand at the post.

For the system, post, device and method as disclosed herein, the at least one strand may comprise fencing wire, and the post may comprise a fence post, whereby a principal (though not exclusive) application of the post, device, method and system is in relation to fencing (e.g. in an agricultural context).

In the system, post, device and method as disclosed herein, the post and device may each be formed from a metal such as steel, aluminium etc, or may comprise a plastic. When of steel the post may be roll-formed such as by a hot roll forming process. The deformed portion(s) or deformation(s) can be imparted to the post during or after roll-forming. For example, when the post is hot roll formed, the deformed portions or deformations can be imparted during that process (e.g. at a final roll- forming stage). Alternatively, they can be formed after hot roll forming, such as in a separate e.g. cold-roll forming stage or process. When the post is moulded the deformed portions or deformations can be formed during the moulding stage. Whilst usually the entire post is formed from a single such material, the device may comprise one or a combination of materials (e.g. a metal and a plastic).

In a usual mode the post and at least parts of the device are formed from a relatively non-deformable metal such as steel whereas flexible parts of the device may be formed from spring steel. Such components may optionally be galvanised or coated. Such coatings may be air dried, force cured or comprise thermal diffusion coatings. Components of the device may optionally be cast or moulded from a cast alloy or metal alloy, or formed from a relatively deformable plastic (e.g. injection moulded from the plastic) to facilitate ease of mounting to a post.

Various embodiments of a system, post, device and method that enable securement of at least one strand to a post will now be described with reference to Figures 1 to 14. Whilst the system, post, device and method will generally be described in relation to the securing of wire strands to a fence post, it should be understood that the system, post, device and method are not limited to fencing-related applications. Further, each of the post embodiments described is of a type that comprises three elongate flanges that each project out from a longitudinal central axis of the post to generally take the form of a Y-post. However, it should be understood that the post embodiments may have more or less flanges or may also take the form of a T-post. Further, the flange to which the device is typically mounted comprises a stalk (i.e. stem or major flange) of the post, although other flanges of the post may be employed. Finally, it should be understood that each of the post embodiments may take the form of a picket (i.e. with a pointed lower end) for ease of post driving into the ground in fencing and related applications, but is not so limited.

Post Embodiment 1

Referring now to Figures 1A to 1G a perspective schematic detail of a first post embodiment is shown in the form of an elongate Y-post 10. The Y-post 10 comprises a major flange in the form of a stalk 12, and minor flanges in the form of wings 14. The Y-post 10 may, for example, be used as a fence post and, in this regard, may have the form of a picket wherein the lower end 15 is cut or machined to be pointed.

In Y-post 10 a portion of a side of the stalk 12 can be deformed relative to a remainder of the side to facilitate mounting of a clip device thereto. In this regard, the deformed portion that enables a given clip device to be mounted to the post can comprise two adjacent indentations 16, 18 that are provided in the stalk 12. The indented direction of indentation 16 is opposed to the indented direction of the other indentation 18. Further, indentation 16 is offset from (i.e. aligned above) indentation 18 as shown.

This deforming of the side of the flange avoids cutting or machining into the flange from a distal edge thereof. Thus, flange strength, integrity, corrosion resistance, etc need not be compromised. The forming of each of the two adjacent indentations 16, 18 can also occur as part of the post forming procedure (e.g. during roll forming or post moulding). Thus, a separate processing stage can be avoided. The density of spacing of indentations 16, 18 along the post may be increased or decreased as desired.

A number of indentation pairs 16, 18 are provided in a discrete spacing arrangement along the stalk 12, with each pair being suitable for mounting a respective clip device to the post, as described hereafter. Such mounting is similar to the manner depicted in Figure 3 (which shows a third post embodiment). The spacing can be such as to correspond to known or pre-existing spacings employed for wires or wire mesh/grid in the fencing industry (e.g. in agricultural applications).

The indentation pairs 16, 18 are easily able to be formed in the post during the roll-forming thereof (e.g. when the Y-post is roll-formed from steel), or can be moulded therein (e.g. when the Y-post is moulded from plastic).

Each of the indentations 16, 18 of Y-post 10 is configured to correspond to a part of a clip device, which part is able is nest within a given indentation when the device is mounted to the post.

Clip Embodiment 1

In this regard, and as shown in Figures 5 and 6, a clip device embodiment is shown in the form of a clip 100. The clip 100 is of a push- or moveable- type in that it comprises, in this particular embodiment, two elements in the form of two opposing moveable plugs 102 and 104. A respective distal end 106, 108 of each plug is shaped and configured such that it is able to be moved so as to nest within a respective one of the indentations 16, 18. The shaping and configuring is such that the plug distal end 106, 108 closely corresponds to the interior profile of the indentations 16, 18, whereby a snug nesting results (see section A-A - Figure 5 A). This helps the clip 100 to better resist removal from and sliding up and down the Y-post in use, and helps it to bear weight/load placed on e.g. the strands in use (such as by animals).

A recess 109 that opposes each plug 102 and 104 is provided in each of a respective projecting part 109A and 109B of the clip 100. Each recess is adapted to receive therein a rear projecting side of the indentations 16, 18 when the clip is slide- mounted to the post.

The clip 100 of Figures 5 and 6 is bifurcated, whereby a lateral passage 110 is defined between a clip upper portion 1 12 and a clip lower portion 114. The clip 100 also comprises a left half 116 and a right half 118, each comprising spigots 119, which can be press- or interference-fit together. The assembled clip defines a vertical passage 120 therethrough which is able to receive the stalk 12 therein during mounting of the clip to the Y-post. During such mounting, the plugs 102, 104 are retracted so as not to extend into the passage 120 and thereby interfere with mounting.

The moveable plug 102 is retained for lateral movement in the upper portion 1 12 and the moveable plug 104 is retained for lateral movement in the lower portion 1 14. The plugs are sized to lock or frictionally engage with the upper and lower portions so that, having been moved to extend into the vertical passage 120, the plugs retain that position. In this regard, an external perimeter of the plugs may be shaped or tapered (see especially section A-A in Figure 6). The shaping may be such as to allow the plugs to snap-lock in the advanced position. Alternatively, the taper may be such that the frictional interaction between the plugs and the respective upper and lower portions increases as the plugs are advanced to extend into the vertical passage 120.

The shaping that enables the plugs to snap-lock may be achieved by moulding the plugs (e.g. when the plugs are moulded from plastic, or are cast or moulded from a cast alloy or metal alloy). The taper configuration may be employed when the plugs are formed from a metal (e.g. steel).

A strand in the form of a length of wire W is able to be located within the passage 1 10 to be retained at the post as shown when the clip 100 is mounted thereto.

It should be understood that a given one of the indentations 16, 18 may be suitable for receiving a clip with a single plug, examples of which will be described hereafter, such as in Figure 9.

It should also be understood that the clip 100 can be employed with a post having adjacent hole pairs, arranged like the holes 26 in the Y-post 20 of Figure 2, but with two closely adjacent holes formed in place of each of the holes 26. Each such hole pair can be suitable for receiving snugly therein the distal ends 106, 108 of the plugs 102, 104 to secure the clip 100 to the post.

Post Embodiment 2

Referring now to Figures 2A to 2G a perspective schematic detail of a second post embodiment is shown in the form of an elongate Y-post 20. Again, the Y-post 20 comprises a major flange in the form of a stalk 22, and minor flanges in the form of wings 24. Again, the Y-post 20 can be used as a fence post and can take the form of a picket (e.g. with a pointed lower end 25). Again, in Y-post 20 a portion of a side of the stalk 22 can be deformed relative to a remainder of the side to facilitate mounting of a clip device thereto. However, in this embodiment, the deformed portion comprises a specially sized and located hole 26 through the stalk 22. In addition, a number or series of such holes 26 can be provided in a discrete spacing arrangement along the stalk 22, with each hole being suitable for mounting a respective clip device to the post (similar to the manner depicted in Figure 3). Again the hole spacing may correspond to a known or pre-existing spacing employed for wires in the fencing industry. Also, the density of spacing of the holes along the post may be increased or decreased as desired.

The holes 26 may be formed in the post during or after the roll-forming procedure (e.g. drilled after roll-forming such as when the Y-post is roll-formed from steel), or can be moulded therein (e.g. when the Y-post is moulded from plastic). In either case, by forming the holes in the side of the flange, cutting or machining into the flange from a distal edge thereof is avoided. Thus, flange strength, integrity, corrosion resistance, etc need not be compromised. Further, when the holes 26 are formed as part of the post forming procedure (e.g. during roll forming or post moulding) a separate processing stage can be avoided. Each hole 26 is configured, tailored and located to correspond to a part of a clip device, which part is able is closely nest within the hole when the device is mounted to the post, thereby optimising each such hole over known holes of known posts.

Clip Embodiment 2

For example, and as shown in Figure 7, another clip device embodiment is shown in the form of a clip 200. The clip 200 is of a fixed-type for push- or press- fitting onto the stalk 22 of a Y-post 20. The clip 200 comprises a plate (e.g. of a metal such as steel or steel alloy) that is bent intermediate its ends to define first and second opposing sides 202, 204 that are interconnected by a web 206.

A tab 208 is formed in one of the sides 202. The tab is pressed, cut, machined or formed out of and from that side, to normally be deflected (i.e. to project) into the space between the opposing sides 202, 204 (see e.g. the tab in the clip of Figure 8). Thus, a proximal end of the tab 208 remains attached in a hinge-like manner to the side 202, whilst a distal end of the tab is offset inwardly and out of the plane of side 202 for location in a given one of the holes 26 in stalk 22.

In this regard, when the clip 200 is push- or press-fitted onto the stalk 22, a front edge of the stalk is guided between the sides 202, 204 and eventually engages the distal end of tab 208, causing it to deflect outwardly and towards the plane of side 202, to enable the clip to be advanced onto the stalk. Further, once the distal end of tab 208 aligns with the hole 26, it flexes or snaps back to its inward orientation, whereby the distal end sits and nests within the hole 26.

The shaping and configuring of the distal end of tab 208 is such that it is able to closely nest within a respective hole 26. In this regard, the corners at the distal end of tab 208 sit close to or abut the inside edge of the hole 26, whereby a close nesting results (see e.g. Figure 7A). This helps the clip 200 resist removal from and sliding up and down the Y-post in use, and helps it to bear weight.

The clip 200 of Figure 7 further comprises upper and lower hook portions 210, 212, extending and bent over inwardly from web 206. Each hook portion 210, 212 is able to retain therebehind, to be secured at a distal edge of stalk 22, a strand in the form of a length of wire (i.e. that is retained once the clip has been securely mounted to the post).

Clip Embodiment 3

Referring now to Figure 8, where like reference numerals are used to denote similar or like parts to Figure 7, another clip device embodiment is shown in the form of a clip 300. Again, the clip 300 is of a fixed-type for push- or press-fitting onto the stalk 22 of a Y-post 20 to secure into a given one of the holes 26. However, the profile of the tab 208' in clip 300 is such that the clip 300 may also be employed with posts having indentations (as opposed to holes), such as the post 10 of Figures 1 and 5, or the post of Figure 3, etc. In this regard, clip 300 can thus be considered to be "dual- purpose".

Again, the clip 300 comprises a plate (e.g. of a metal such as steel or steel alloy) that is bent intermediate its ends to define first and second opposing sides 202, 204 that are interconnected by a web 206. The clip 300 also comprises upper and lower hook portions 210, 212, each for retaining a strand (e.g. wire) therebehind to secure it at a distal edge of the stalk 22, once the clip has been securely mounted to the post.

However, the clip 300 comprises a modified tab 208' which has a distal end that is shaped and configured such that it is able to nest snugly within a respective hole 26 (or indentation 16 or 18). In this regard, the distal end of tab 208' has a curved shape around a substantial portion of its perimeter. This enables the edge of the tab distal end to sit snugly against (e.g. to abut) either the inside edge of hole 26, or the edge of an indentation 16 or 18.

Figure 8 also illustrates that the side 204 has an aperture 21 1 provided therein in a location opposing the location of tab 208' (aperture 211 is not shown but is optionally and optimally present in the clip 200 of Figure 7). The aperture 21 1 enables the tab 208' to be accessed for displacement out of engagement with the post (e.g. for clip removal therefrom). However, when the clip 300 is used with a Y-post having indentations 16 and/or 18 therealong, the aperture 21 1 allows the reverse side of those indentations (i.e. the protruding rear of each indentation) to be accommodated in the side 204 of the clip. In this regard, the aperture 21 1 can be sized to snugly receive the indentation therein, to further enhance clip securement to the stalk 22. In this regard, it can work together with tab 208'.

Figure 8 further illustrates how free ends 214 and 216 of the sides 202, 204 are outwardly curved or flared to facilitate push- or press-fitting of the clip 300 onto the stalk 22 (this feature is also present on clip 200 of Figure 7, but is more clearly illustrated in Figure 8).

In the clip 300 the tab 208' is again pressed, cut, machined or formed out of and from side 202, to deflect/project into the space between the opposing sides 202, 204 (see e.g. section A-A) whereby a proximal end of the tab 208' remains attached in a hinge-like manner to the side 202 at a hinge region 209.

When the clip 300 is push- or press-fitted onto the stalk 22, the stalk passes through the flared opening defined by free ends 214 and 216. A front edge of the stalk then engages inside faces of the opposing sides 202, 204, causing them to be deflected outwardly. In addition, the front edge of the stalk eventually engages the tab 208' and causes it to be deflected towards the plane of side 202, to enable the clip to be further advanced onto the stalk. Once the distal end of tab 208' aligns with the hole 26, or with one of the indentations 16, 18, it flexes or snaps back to its inward orientation, whereby the distal end sits and nests snugly within the hole 26 or indentation 16 or 18. Similarly, the rear of one of the indentations 16, 18 is received in aperture 211. This snug nesting better helps the clip 300 resist removal from and sliding up and down the Y-post in use, and helps it to be weight/load bearing.

Post Embodiment 3

Referring now to Figure 3, where like reference numerals to Figure 1 are employed for similar or like parts, a perspective schematic detail of a third post embodiment is shown in the form of an elongate Y-post 10'. The Y-post 10' again comprises a stalk 12, and wings 14. When the Y-post 10' is used as a fence post picket, a lower end can be cut or machined to be pointed (not shown in Figure 3).

In Y-post 10' a portion of a side of the stalk 12 is again deformed relative to a remainder of the side to facilitate mounting of a given clip device thereto. Indeed, in Figure 3, a number of different clip device embodiments are shown, in an illustrative manner, as mounted to and spaced out along the stalk 12.

In Y-post 10' the deformed portion that enables a given clip device to be mounted to the post comprises a series of single, aligned and spaced indentations 16 that are provided in and along the stalk 12. The indented direction of each indentation 16 is generally the same, although adjacent indentations may have an alternating opposed indented direction, etc.

The spacing of the indentations 16 can be such as to correspond to a known or pre-existing spacing employed for wires or wire mesh in the fencing industry (e.g. in agricultural applications). Also, the density of spacing of indentations 16 along the post may be increased or decreased as desired.

Again, the series of indentations 16 in Y-post 10' are easily able to be formed in the post during the roll-forming or during moulding.

Clip Embodiment 4

Referring now to Figure 9, another clip device embodiment is shown in the form of a clip 400. Like the clip embodiment of Figures 5 and 6, the clip 400 is of a push- or moveable- type. However, in this particular embodiment, the clip 400 comprises a single element in the form of a plug 402 that is moveable in a body 404 of the clip 400. A respective distal end 406 of the plug 402 is shaped and configured such that it is able to be moved so as to nest within a respective one of the indentations 16, 18, or to locate in a hole 26, of the various Y-post embodiments described herein. Again, to help the clip 400 better resist removal from and sliding up and down the Y-post in use, and to be weight/load bearing, the shaping and configuring of the plug and the indentations 16, 18, or hole 26, is such that the plug distal end 406 closely corresponds to the interior profile of the indentations 16, 18, or edge of hole 26, whereby a snug nesting results.

The clip 400 comprises a left half 416 and a right half 418, each comprising spigots 419, which can be press- or interference-fit together. The assembled clip defines a vertical passage 420 between projection portions 422 and 424 of the left and right halves 416, 418. The projection portions 422, 424 are able to receive the stalk 12, 22 therein during mounting of the clip to the Y-post. In this regard, during mounting, the plug 402 is moved with respect to portion 422 so as be retracted from and to not extend into the passage 420 (which would otherwise interfere with clip mounting) and, once aligned, is advanced (e.g. pushed or pressed) into the indentation/hole.

Again, a hole 425 that opposes plug 402 can be provided in the projecting portion 424 to receive a rear projecting side of indentation 16, 18, or to enable access to the plug for release from the hole 26.

However, unlike the clip 100, clip 400 is not bifurcated so does not include a lateral passage for wire/strand retention. Instead, in the assembled clip 400, upper 426 and lower 428 hook arrangements are defined, each for receiving and capturing a respective wire/strand against a distal edge of the stalk 12, 22.

Again, the plug 402 is sized or shaped to snap-lock or frictionally engage with the clip body 404 so that, having been moved to extend into the vertical passage 420, the plug retains that position. In this regard, an external perimeter of the plug can be shaped for snap-locking or tapered (see especially section A-A). When tapered, the frictional interaction between the plug and the clip body can increase as the plug is advanced to extend into the vertical passage 420. It should be understood that the plug and stalk can each be adapted such that a given one of the indentations 16, 18 or hole 26 can be suited to receive therein the plug 402 of clip 400.

Post Embodiment 4

Referring now to Figure 4, a perspective schematic detail of a fourth post embodiment is shown in the form of an elongate Y-post 500. The Y-post 500 again comprises a stalk 502, and wings 504. When the Y-post 500 is used as a fence post picket, a lower end can be cut or machined to be pointed (not shown in Figure 4).

In Y-post 500 a portion of a side of the stalk 502 is again deformed relative to a remainder of the side to facilitate mounting of a clip device thereto. However, in this post embodiment, the deformed portion that enables the clip device to be mounted to the post comprises a series of adjacent and opposed groove couples 506 and 508 that are provided in either side of the stalk 502.

For a given groove couple, each groove 506 or 508 is formed (e.g. machined or rolled into the stalk side) to extend in laterally from a distal edge of the stalk 502, with the groove 506 starting slightly lower down the stalk distal edge than the groove 508. This close but offset spacing of the grooves 506, 508 can be employed to advantage with a spring-loaded clip, to help retain and secure the clip on the post (as described hereafter with reference to clip 600).

Each groove comprises an enlarged head region 510 at its innermost end, with the head region 510 of groove 506 projecting downwards with respect to the stalk, and with the head region 510 of groove 508 projecting upwards with respect to the stalk (see especially figures 4A & B). Each head region 510 also comprises a bearing surface 512 along an edge thereof, against which a distal edge of a clipping device can be closely received (e.g. abut) to bear thereagainst. In groove 506 the bearing surface 512 extends along a lowermost edge of the head region 510, and in groove 508 the bearing surface 512 extends along an uppermost edge of the head region 510. A retention shoulder 514 is defined at the intersection of each groove with its respective head region.

The spacing of the groove couples 506, 508 along the stalk 502 can be such as to correspond to a known or pre-existing spacing employed for wires or wire mesh/grid in the fencing industry (e.g. in agricultural applications). Also, the density of spacing of the groove couples 506, 508 along the post may be increased or decreased as desired.

Again, the groove couples 506, 508 are easily able to be formed in the post during or after roll-forming or during moulding.

Clip Embodiments 5 to 9

Referring also to Figure 4, a clip device embodiment that is suitable for the post 500 is shown in the form of a clip 600. Again, the clip 600 is of a fixed-type for push- or press-fitting onto the stalk 502 of Y-post 500 to secure it in relation to a given one of the groove couples 506, 508.

The clip 600 comprises a plate (e.g. of a metal such as steel or steel alloy, or of a plastic) that has been pressed/cut and bent, or moulded, to define upper arms 602, 604 and lower arms 606, 608 that are interconnected by a tubular body 610, and about which body a spring-action and spring-loading of the clip is able to be generated. In this regard, the upper arms 602, 604 can be urged towards the lower arms 606, 608 to spring-load the clip. In addition, the left side arms 602, 606 can be urged away from the right side arms 604, 608 to also spring-load the clip. Such loadings of the clip 600 can occur during mounting of the clip to the post 500 and can assist in clip retention on the post.

As shown, the tubular body 610 is configured to have a wire strand W inserted therethrough for retaining and securing the strand at a distal edge of the stalk 502, i.e. once the clip 600 has been securely mounted to the post.

A distal end of each arm is shaped and configured such that it is able to nest within a respective head region 510 of one of the grooves 506 or 508. In this regard, the clip is symmetrical whereby it can be inverted and still be used in the same manner. The clip 600 defines an in-use vertical gap 612 that extends through the clip to space/separate the upper arms 602, 604 and the lower arms 606, 608. The vertical gap 612 receives the stalk 502 of post 500 therein when the clip is mounted to the post as shown.

Each distal end of each arm (602, 604, 606, 608) is enlarged to define a lug 614 that extends along an inside edge thereof and that projects into the vertical gap 612 as shown. An inside corner 616 of the distal end of each arm (602, 604, 606, 608) is also rounded to aid with pushing/pressing of the clip onto the stalk 502.

As depicted, when the clip 600 is mounted to the post 500, a lug 614 of the lower left arm 606 is adapted to nest within a respective head region 510 of the groove 506. Similarly, a lug 614 of the upper right arm 604 is adapted to nest within a respective head region 510 of the groove 508. The lug 614 of the upper left arm 602 sits adjacent to a side of the flange 502 and, similarly, the lug 614 of the lower right arm 608 sits adjacent to an opposite side of the flange 502.

The spacing between opposing lugs 614 of the upper arms 602, 604 and between opposing lugs 614 of the lower arms 606, 608 is set to be narrower than the width of the stalk. This urges the left side arms 602, 606 away from the right side arms 604, 608 to spring-load the clip 600. Thus, when the clip 600 is positioned into the stalk as shown, the lug 614 of the lower left arm 606 and the lug 614 of the upper right arm 604 are each urged into their respective head region 510 of the grooves 506 and 508.

To facilitate this mounting, the upper arms 602, 604 and lower arms 606, 608 are urged together (e.g. pressed by a tool or squeezed manually) to induce another spring action in the clip. Once suitably positioned on the post, and when the clip is released, the spring action between the upper arms 602, 604 and lower arms 606, 608 is such that the lug 614 of the lower left arm 602 is caused to bear against the bearing surface 512 of the head region 510 in groove 506. Similarly, the lug 614 of the upper right arm 604 is caused to bear against the bearing surface 512 of its respective head region 510 in groove 508. The vertical line spacing between the bearing surfaces 512 of grooves 506, 508 is less than the ordinary (non-pressured) spacing of the lugs in the upper arms 602, 604 and in the lower arms 606, 608. Thus, the lugs 614 are biased against their respective bearing surfaces 512. The lugs also sit behind a respective retention shoulder 514 to be retained on the stalk 502.

This snug, loaded nesting better helps the clip 600 to resist removal from and sliding up and down the Y-post 500 in use.

In Figure 4 only two of the arms 606 and 604 are used to secure the clip 600 to the Y-post 500. The lugs 614 of the other two arms 602 and 608 merely sit against the side of the flange 502. However, it is possible to modify the post so that each groove has an additional enlarged head extending up on one side and down on the other, to retain both the upper and lower arms 602 and 606 on one side, and the upper and lower arms 604 and 608 on the other side of flange 502.

Again, the grooves 506, 508 are configured and tailored to correspond to the arms of the clip 600.

A sixth embodiment of a clip 700 is shown in Figure 10. Clip 700 also has a body 702, with projections 704A, 704B extending therefrom to define a recess 706 therebetween. The recess 706 is configured to receive, for example, part of a flange of a Y-post therein. Projection 704A has an element in the form of a detent 708 formed therein. Detent 708 comprises an indentation 710 on one side of projection 704A (i.e. the in-use outer surface) and a corresponding protrusion 712 on the other (i.e. at the inner surface that contacts the deformed surface of the Y-post).

Projection 704B has an aperture 714 therethrough, at a location corresponding to the detent 708. While the clip 700 may be utilised with a Y-post having a deformed surface portion in the form of a hole, typically it is used with a post of the type having a detent therein. In this regard, when clip 700 is attached to the Y-post, the projections 704, having outwardly flared distal ends 715, and detent 708 are deflected past the post as the clip is pushed or pressed thereon. Once the clip is sufficiently advanced, projection 704A and detent 708 align with the post indentation and deflect (snap) back to their original positions, whereas the projection 704B deflects (snaps) back to its original position whereby aperture 714 receives therein the rear protrusion on the other side of the post flange.

Clip 700 also has two cutaway portions 716 extending into the body 702 and projections 704 to form a passage 718 therein. Passage 718 extends transversely across a rear of the clip 700 that faces in to the post when the clip 700 is attached to the post. Passage 718 is configured to receive an elongate strand therein, such as fence wire. Each cutaway portion 716 has opposing fingers 720 extending from adjacent upper and lower portions of the body 702 and into the cutaway portion 716. Two cutaway portions 716 and two fingers 720 in each cutaway portion are shown, whereby four different strand positions along a Y-post are provided for each clip 700. One or more of these positions may be used. The fingers 720 are angled in towards the flange of a post in use such that, when an elongate strand is placed in the passage and behind each finger, the fingers 720 assist with retaining the elongate strand at the flange distal edge. In this regard, once the clip 700 is mounted to the post, each finger can sit close to or abut the flange distal edge. In order for the fingers 720 to abut the flange distal edge, it may be necessary to rotate the clip 700 about the detent (i.e. push an upper or lower portion of the body 702 of clip 700 towards the post flange distal end, once connected thereto, thus rotating the clip and fingers about detent). While the strand may be placed into passage 718 before or after clip 700 has been attached to the post, an easier mode of attachment involves positioning the strand(s) in the passage 718 after the clip 700 is fully attached to the post. Once the strand(s) are in place, the clip 700 can be rotated so that the finger 720 that retains the strand in the passage 718 abuts the flange distal edge.

A seventh embodiment of a clip 800 is shown in Figure 1 1. Clip 800 is similar to clip 700 except that body 702 is shorter in clip 700, and clip 800 only comprises one cutaway portion 816. This cutaway portion 818 is also provided with two fingers 820 to assist with retaining one or two elongate strands in passage 818.

Referring now to Figure 12, an eighth embodiment of a clip 900 is shown. Clip 900 has a curved tubular body 902 with two projections 904A and 904B extending therefrom, the two projections 904A, 904B defining a recess 906 therebetween. Recess 906 is configured to receive, for example, part of a flange of Y-post therein.

Both projections 904A and 904B comprise an element in the form of a detent 908. Detent 908A of projection 904A protrudes into recess 906 whereas detent 908B protrudes out from projection 904B. This is because detent 908A is configured to locate in a hole or indentation of a Y-post, whereas detent 908B is configured to receive the protrusion of a post detent. Whilst the clip 900 is primarily configured to be utilised with a Y-post having a series of detents, it may also be used with a post having a series of holes.

Tubular body 902 also extends beyond (i.e. above and below) the projections 904, to define upper and lower heads 922. Cutaway portions 924 are provided in each of the heads 922 to define transverse passages 918 at a rear of the clip 900 that faces in to the post when it is attached thereto. Each passage 918 can receive an elongate strand (e.g. fence wire) therein. When the clip 900 is attached to a post, heads 922 abut or closely face the distal edge of the flange to retain each strand in passage 918.

Again, when attaching clip 900 to post, strand(s) are pre-loaded into passage 918 and the flared distal ends 926 are pushed past the flange of a Y-post biasing the projections out and allowing the detent 908A to deflect out past the flange distal edge until it aligns with the indentation in the post. Similarly, detent 908B aligns with the protrusion on the post.

A ninth embodiment of a clip 950 is shown in Figure 13. The spaced upper and lower projections 954' and 954", respectively, extend from body 952. An in-use vertical recess 956 is formed between projections 954A (which comprises projections 954A' and 954A") and 954B (which comprises projections 954B' and 954B"), for receiving therein the flange of a Y-post. A lateral passage 958 is also shown extending between the upper projections 954' and lower projections 954" for receiving an elongate strand therein. The passage 958 extends the length of the projections 954' and 954" to the body 952 of the clip 950.

Each of the upper and lower opposing projections 954', 954" is shown having an element in the form of a detent portion 960. Each detent portion 960 is in the form of a semi -circular indentation 962 on one side of the projection and a corresponding semicircular protrusion 964 on the other (i.e. upper projection 954A' and lower projection 954A" each comprise a semi-circular indentation 962 on their in-use outer surface and a corresponding protrusion 964 on their in-use inner surface. Upper projection 954B' and lower projection 954B" each comprise a semi-circular indentation 962 on their in-use inner surface and a corresponding protrusion 964 on their in-use outer surface).

Detent portion 960A (in projection 954A) is configured to be positioned in a hole or indentation of a Y-post, whereas detent 960B is configured to receive the protrusion of a detent on the post. The projections 954 and detent portions 960 deflect as clip 950 is pushed onto flange of a Y-post before they align with detent or hole, whereupon the detent portions 960 deflect back to their original positions. An elongate strand is typically placed in passage 958 prior to clip 900 being secured to a Y-post. Post Embodiments 5 & 6

Referring now to Figure 14A, a fifth post embodiment is shown in the form of an elongate Y-post 10". The Y-post 10" is somewhat similar to the post 10 of Figure 1 and again comprises a stalk 12, and wings 14. Again, the Y-post 10", when used as a fence post picket, has a cut or machined pointed lower end 15.

The indentation pairs 16, 18 in Y-post 10" are spaced along the post so as to be suitable for locating a wire grid G. The spacing of wires in the grid G may be known or pre-existing in the industry. In this regard, a clip device (not shown), and such as those illustrated in Figures 5, 6 or 8 to 13, can be mounted to a given number (e.g. all or a suitable number of) the indentation pairs 16, 18 to retain an adjacent respective strand of the wire grid G at the Y-post 10". In this respect, the post has been optimised to the wire grid G.

Referring now to Figure 14B, a sixth post embodiment is shown in the form of an elongate Y-post 20'. The Y-post 20' is somewhat similar to the post 20 of Figure 2 and again comprises a stalk 22, and wings 24. Again, the Y-post 20' when used as a fence post picket, has a cut or machined pointed lower end 25.

The holes 26 in Y-post 20' are spaced along the post so as to be suitable for locating another wire grid G' (i.e. with different spacing of wires). In this regard, a clip device (not shown), and such as those illustrated in Figures 3, or 7 to 13 can be mounted to a given number (e.g. all or a suitable number of) the holes 26 to retain an adjacent strand of the wire grid G' at the Y-post 20'. In this respect, the post has been optimised to the wire grid G'.

The posts 10", 20' can be provided with multiple additional indentations or holes along its length so that one such post is able to have a number of differently spaced and configured wire grids or meshes secured thereto. The density of spacing of indentations or holes along the post may be increased or decreased to suit small or large gauge grid or mesh.

Examples

Non-limiting Examples of a method and system for securing at least one strand to a post will now be provided. Example 1

The following generalised method was observed to apply to the various embodiments of the posts and clip devices as shown in and as described for Figures 1 to 14. In a general sense the method comprised the steps of:

1. Mounting to a given location along the post (10, 10', 10", 20, 20' or 500) a clip device (100, 200, 300, 400, 600). One or more devices were mounted so that a given distal end of a part of each device was able to nest within a respective deformed portion or deformation of the post (e.g. an indentation 16, 18, or a hole 26, or a groove 506, 508).

2. Positioning and securing one or multiple strands (W, G or G') with respect to each device at a desired location along the post.

In general, each strand was secured at the device prior to mounting. However, in some cases it was possible (such as by threading) for the strand to be secured with respect to the device after it was mounted to the post.

The method was observed to reduce the amount of manual and skilled labour when securing the strands to a post. The method also reduced the need for specialised tools. In applying the method the strands were able to be easily located and rapidly secured to the post, all whilst out in the field.

Example 2

The post 10 of Figure 1 was employed with either the clip 100 of Figures 5 and

6 or the clip 400 of Figure 9. The post 10 was first driven into the ground to the desired depth using a manual or motor driven fence post driver. The indentation pairs 16, 18 located at a lower portion of the post and that were submerged below ground level were observed to increase the in-ground holding capacity of the post (i.e. to increase post pull-out force).

A wire strand W was then loaded into the lateral passage 110 of a given clip 100, or one or two wire strands were located under the upper and lower hook portions 426, 428 of clip 400. However, the wire was able to be threaded through the clip 100 or 400 after it was mounted to the post. Each plug 102, 104 or 402 was also retracted out of the vertical passage 120, 420 prior to mounting. The clip 100 or 400 was then laterally slid into place on the post 10 at a desired location of a given indentation pair 16, 18. Once the plugs 102, 104 or 402 were aligned with a respective indentation 16, 18, they were pressed/pushed inwardly (e.g. manually or with a suitable tool such as multi-grips) so that the distal ends 106, 108, 406 of the plugs located snugly in a respective indentation 16 and/or 18. The snap- locking or increasing frictional interaction of the plugs 102, 104, 402 with the clip helped to retain the plugs in their advanced orientation, to better secure the clip 100 or 400 to the stalk 12. The clip 100 or 400 thus easily and rapidly secured the wire strand(s) W at a distal edge of the stalk.

Example 3

The post 20 of Figure 2 was employed with either the clip 200 of Figure 7 or the clip 300 of Figure 8. The post 20 was driven into the ground to the desired depth using a manual or motor driven fence post driver. Again, the lower holes 26 that were submerged below ground level were observed to increase the in-ground holding capacity of the post (i.e. to increase post pull-out force).

One or two wire strands W were then located under one or both of the hook portions 210, 212. The clip 200 or 300 was then laterally pressed or pushed into place onto the stalk 22 of post 20 at a desired location of a given hole 26, with a distal edge of the stalk passing between the flared ends 214, 216. As the stalk distal edge moved passed the tabs 208 or 208' it caused them to deflect towards the plane of the side 202 until the tab 208 or 208' aligned with the hole 26, whereupon the tab snapped back to its original position to now locate in the hole 26. The close interaction between the tab and the hole edge served to secure the clip 200 or 300 to the stalk 22, with the clip also securing the wire strand(s) W at the distal edge of the stalk.

When the clip 300 was secured onto a post with indentations 16 and/or 18 (e.g. such as that shown in Figure 3), the mounting procedure was similar to that for post 20. However, when the flared end 216 engaged a protruding rear of the indentation, the side 204 was deflected out until the aperture 211 aligned with the protruding rear of the indentation, whereupon the side 204 snapped back. Once so located, this receipt of the protruding rear in aperture 211, together with the tab 208' located in the indentation, further helped secure the clip 300 to the stalk 22. Example 4

The post 500 of Figure 4 was employed with the clip 600 of Figure 4. The post 500 was first driven into the ground to the desired depth using a manual or motor driven fence post driver. Again, the lower grooves 506, 508 that were submerged below ground level were observed to increase the in-ground holding capacity of the post (i.e. to increase post pull-out force).

A wire strand W was then loaded into the tubular body 610 of a given clip 500. However, the wire was able to be threaded through the clip 600 after it was mounted to the post.

The clip 500 was then squeezed (e.g. manually or with a suitable tool such as pliers or multi-grips) so that the upper arms 602, 604 moved towards the lower arms 606, 608, whereby the lower left arm 606 was able to align with the opening of the groove 506, and the upper right arm 606 was able to align with the opening of the groove 508. This imparted a reactive spring force within the clip.

The clip 600 was then laterally slid into place on the stalk 502 of the post 500 at a desired location of a given groove pair 506, 508. This allowed the lugs 614 of the lower left arm 606 and the upper right arm 604 to pass into and along the grooves 506 and 508.

In addition, during such slide mounting on the stalk 502, the upper left arm 602 and the lower right arm 608 were urged passed the stalk distal edge (i.e. as facilitated by the curved inside corners 616), and then slid across a respective side face of the stalk. This caused the upper left arm 602 and the lower right arm 608 to be slightly urged apart, setting up another reactive spring force within the clip.

Once the lugs 614 of the lower left arm 606 and the upper right arm 604 were aligned with a respective head region 510 of the grooves, the clip was released, whereby the reactive spring forces caused each of the lugs 614 of arms 606 and 604 to be urged towards and to bear against a respective bearing surface 512. Then, the resulting interaction of the lugs with their respective adjacent retention shoulder 514 functioned to secure the clip 600 to the stalk 502. The clip 600 thus easily and rapidly secured the wire strand W at a distal edge of the stalk. Example 5

The post 10" of Figure 14A and the post 20' of Figure 14B were able to employed with various of the clips of Figures 3, and 5 to 13. A given post was first driven into the ground to the desired depth. A number (e.g. some or all) of the horizontal wire strands of the grid G or G' were then loaded into a respective clip. Each of the clips were then secured to a respective indentation 16 and/or 18 or hole 26 to easily and rapidly secure the grid G or G' at a distal edge of the stalk.

Example 6

In a system for securing multiple wire strands to a post, each post was supplied together with a number of clips. For example, the system was able to be supplied as a kit of parts, including post, a number of clips per post and, optionally, a tool (e.g. suitably sized pliers or multi-grips) for applying each of the clips to the post.

With each of the post and clip systems it was noted that the level of securement was sufficient to enable the wire strand to bear weight/load, for example, at levels up to 300kgs. The post and clip systems enabled the weight to be transmitted via the clip to the post, so that the weight was supported at the post and the load was on-transmitted to ground.

Example 7

In another system the clips were designed to release from the post at a given level of weight or loading. In this regard, the material for and the extent or degree of nesting of the distal end of that part of the device that nests in the deformation or deformed portion was carefully designed and selected to release from the post at the given level of loading.

When, for example, such a system was employed in a fence line, and a part of the fence line was subjected to a relatively higher load (such as during a flood, or during dismantling of a section of a fence, or during accidental impact such as by agricultural machinery or a herd of animals, etc) then the clips were able to detach from the post to allow for release of fencing wires, etc. In such case, a remainder of the fence line was not damaged, or the extent of damage was minimised. Example 8

A Y-post as disclosed herein was roll-formed from steel in a hot roll forming process. The indentations 16 and/or 18, holes 26 or grooves 506, 508 were formed in the post during (as part of) the roll-forming procedure. In this regard, the indentations, holes, or grooves were imparted to the side of the stalk at a final roll pass of the process (i.e. in-line, and during the process). This provided cost and manufacturing efficiencies.

In a variation of this process, the indentations, holes, or grooves were formed in an additional cold-roll forming procedure. This allowed for careful control of and precision in the formation of the indentations, holes, or grooves.

In a process where the post was moulded from plastic the indentations, holes, or grooves were formed during moulding.

The systems, posts, clip devices and methods as outlined in the drawings and Examples were observed to enable a user such as a farmer to simply and rapidly construct a fence line, without the need for complex tools. The systems, posts, clip devices and methods as outlined in the Examples were also easy and cost-effective to manufacture. Whilst a number of specific system, post, clip device and method embodiments have been described, it should be appreciated that the system, post, clip device and method may be embodied in many other forms.

For example, the strand to be attached to the post can include elongate components such as rod, bar, etc. The post need not be limited to upright posts and pickets and can include rails, cross-members, struts, stays, channels, etc which in use extend other than vertically.

The clip devices can be bent and machined from plate metal, or cast or moulded to the required shape or configuration. The clip devices can be formed from or include components of a deformable material (e.g. such as a plastic or bendable metal). At least some of the clip devices can be loaded into a purpose-built "clip" gun that is manually activated or e.g. pneumatically, gas or electrically powered and be able to rapidly increase the speed and ease of mounting of the clip devices to a post.

Whilst a usual application of the system, post, clip device and method is in fencing, to secure wire strands or mesh/grid to a post, the system, post, clip device and method can be employed in applications such as demarcation, signage, retention, barricades etc. In this regard, the device may be adapted (e.g. modified) to enable it to secure other components to the post, such as barriers, signage (e.g. of a core-flute design), etc.

Also, whilst the posts are usually roll-formed from steel to have a Y-shaped or T-shaped profile, and are usually cut at the end to take the form of a picket, the posts can optionally be moulded from a plastic material (e.g. for use in electric fencing).

In the claims which follow, and in the preceding description, except where the context requires otherwise due to express language or necessary implication, the word "comprise" and variations such as "comprises" or "comprising" are used in an inclusive sense, i.e. to specify the presence of the stated features but not to preclude the presence or addition of further features in various embodiments of the system, post, clip device and method as disclosed herein.
