Abstract
A chain link assembly having a plurality of wires, each wire being interwoven with at least one adjacent wire, and each wire having two ends, with each end being 5 connected to an end of an adjacent wire, and a first flexible strip of material to at least partially cover one end of each of the plurality of wires.

Description
FIELD OF INVENTION
The present invention relates to a chain link assembly. The present invention 5 has particular but not exclusive application for a chain link fencing assembly. The patent specification describes this use but it is by way of example only and the invention is not limited to this use.
BACKGROUND OF THE INVENTION
Chain link is often used in chain link fencing. Chain link fencing may also be referred to as wire netting, wire-mesh fence, chain-wire fence, cyclone fence, hurricane fence, or diamond-mesh fence. Chain link fencing is a woven type of fencing made from coated or uncoated steel wires.
Each steel wire is woven together with an adjacent wire, with the number of wires woven together typically defining a length of the chain link fence. The length of each wire in the woven condition (i.e. flattened spiral condition) typically defines a height of the chain link fence.
The ends of each wire are typically twisted or knuckled together with an end of an adjacent wire to prevent the wires from coming apart.
Chain link fencing is typically delivered to site in rolls of predetermined length.
Multiple rolls can be joined together by ‘screwing’ a (flattened spiral) wire into two adjacent fencing sections. A benefit of this is that any desired length can be achieved on site by joining the required amount of rolls together.
A problem with rolls of chain link fencing is that twisted or knuckled ends of wires can become entangled with other twisted ends of wires or other portions of the chain link fencing, which can require time consuming manual separation, can lead to damage of the chain link fencing, and can increase the risk of injury.
OBJECT OF THE INVENTION
It is an object of the present invention to overcome or at least alleviate one or more of the above mentioned problems with chain link fencing and/or provide the consumer with a useful or commercial choice.

BRIEF DESCRIPTION OF THE DRAWINGS
In order that the present invention can be more readily understood reference will now be made to the accompanying drawings which illustrate a preferred embodiment of the invention and wherein:
Figure 1 is a front view of a chain link assembly according to an embodiment of the present invention;
Figure 2 is a side view of a chain link assembly according to another embodiment of the present invention; and
Figure 3 is a perspective view of the chain link assembly of Figure 2.
DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
With reference to Figure 1 there is shown a chain link assembly in the form of chain link fencing 10. The chain link fencing is made of a plurality of steel wires 12,13,14,15,16 (only some numbered for clarity). The wires 12,13,14,15,16 are in the shape of a flattened spiral and are interwoven with adjacent wires.
Ends of the wires 12,13,14,15,16 (ends not shown) are connected to adjacent ends of wires to prevent the wires 12,13,14,15,16 coming loose. The ends of the wires 12,13,14,15,16 are covered by a first flexible strip of material 18. The first flexible strip of material 18 is a strip of vinyl material. The first flexible strip of material 18 is folded over to cover the ends of the wires 12,13,14,15,16.
2019100492 07 May 2019
-7The first flexible strip of material 18 is attached to the wires by stapling two portions of the first flexible strip of material 18 together using staples 20. The staples 20 are stapled through openings 22 defined by the wires 12,13,14,15,16.
The chain link assembly 10 also has a second flexible strip of material (not 5 shown) located at a lower edge of the chain link assembly 10, attached in a similar manner to the first flexible strip of material 18.
With reference to Figures 2 and 3, there is shown a schematic side section view and a schematic perspective view of a chain link assembly in the form of chain link fencing 100. The chain link fencing 100 has a first flexible strip of material 118 (only partially illustrated in Figure 3 for clarity) which is folded over ends of wires (e.g. 112a,113a). Two opposed portions 118a,118b of the first flexible strip of material 118 are attached to each other by adhesive.
In use, with reference to figures 1-3, when the chain link assemblies 10,100 are rolled up for storage and/or transport, the first flexible strip of material 18,118 inhibit ends of the wires 112a,113a (only shown in figures 2 and 3) from tangling with wire ends of wires from overlapping portions of the chain link assemblies 10,100.
ADVANTAGES
An advantage of the preferred embodiment of the chain link assembly includes the ability to reduce snagging when rolling and unrolling the chain link assembly. Another advantage of the preferred embodiment of the chain link assembly includes covering sharp ends of the plurality of wires. A further advantage of the preferred embodiment of the chain link assembly includes providing a more visual edge to the chain link assembly.
VARIATIONS
While the foregoing has been given by way of illustrative example of this invention, all such and other modifications and variations thereto as would be apparent to persons skilled in the art are deemed to fall within the broad scope and ambit of this invention as is herein set forth.
Throughout the description and claims of this specification the word “comprise and variations of that word such as “comprises” and “comprising”, are not intended to exclude other additives, components, integers or steps.
