Fences are commonly used to confine livestock, such as farm animals, steers, and thoroughbred race horses. Fences may vary greatly in both structure and materials used in their construction. Fence structures which were traditionally available include those made of wire, (barbed wire, chain link, etc.), and wood (picket, split rail, etc.).
The materials used to construct a particular fence are often selected on the basis of initial costs, upkeep cost, durability, strength, aesthetic characteristics and animal safety requirements. The most commonly used materials include metal and/or wood. While concrete and stone are readily available, the cost is often prohibitive.
The most commonly used fencing material for livestock has been barbed wire. This is due to the low cost of installation and maintenance that such material presents. However, barbed wire can cause painful and unsightly injury to valuable livestock. Also, such material is difficult for the animal to detect and, all too often, the animal is injured during contact with this unseen barrier. Other materials, such as web wire fencing and cyclone wire fencing suffer from similar limitations. In addition, they tend to be expensive to install and maintain and, over time, can also operate to injure livestock.
Wood fences, on the other hand, while expensive to install and maintain, generally do not operate to injure livestock. Wood fences also offer a more pleasing aesthetic appearance.
In order to solve the difficulties presented by commonly available wire and wood fences, a fencing system using high tensile wire jacketed by polymer or vinyl coating has been developed. This type of fencing is typified by that illustrated in FIG. 8 of U.S. Pat. No. 4,706,942, as well as in U.S. Pat. Nos. 4,465,263; 4,860,996 and 6,834,846. The text and figures of these patents are incorporated by reference as if set forth fully herein.
Another method and apparatus for forming a fence line system comprised of a plurality of fence post members that are disposed in an array so as to enclose or divide a given area of land is typified by that illustrated and described in U.S. Pat. No. 6,152,429. Alternative connectors that can be used to terminate or splice polymer jacketed high tensile wire fencing are disclosed in U.S. Pat. No. 7,566,047.
While the systems of polymer jacketed high tensile wire fencing presents a satisfactory solution to some of the above-mentioned problems, there is still a need for an improved coupling arrangement for use in a termination and/or splice system which is relatively inexpensive, durable, strong, safe for physical contact with livestock, and ultimately easy to install. Desirably such an improved coupling arrangement would also provide for a simple disassembly by way of a quick release.
The coupling arrangement can include a plate having first and second edges that are generally parallel to each other. A slot passes through the plate generally perpendicular to the first and second edges, the slot having upper and lower ends that are spaced from the first and second edges. A fold in the polymer jacketed high tensile wire fencing can be arranged to define a bight joining a shorter portion of the fencing to a longer portion of the fencing. The fold can be caused to penetrate the slot of the coupling. A pin can have a length greater than the distance between the upper and lower ends of the slot. The pin can have one end inserted into the bight in the fold of the fencing and another end situated to engage one of the first and second edges of the plate to retain the fold of the fencing in the slot.
In one embodiment the plate can include a third edge extending between the first and second edges generally parallel to the slot and a fourth edge opposite the third edge. The fourth edge can be parallel to the third edge. Each of the first and second edges can additionally include a tab extending outward in general alignment with the fourth edge of the plate, each tab including an opening to receive a fastener. The fasteners can couple the tabs of the plate to an adjacent fence post. Optionally, the fourth edge of the plate can be positioned so that the tabs straddle a second polymer jacketed high tensile wire fencing to secure the second fencing to an adjacent fence post.
In an alternative embodiment, the plate can include a third edge extending between the first and second edges generally parallel to the slot and a fourth edge opposite the third edge. The fourth edge can be parallel to the third edge. The plate can include a second slot parallel to the first slot to receive a fold of a second polymer jacketed high tensile wire fencing that can define a bight joining a shorter portion of the second fencing to a longer portion of the second fencing. The fold of the second fencing can penetrate the second slot of the coupling. A second pin can be provided. The second pin can have an end inserted into the bight in the fold of the second fencing. The second pin can have another end engaging one of the first and second edges of the plate to retain the fold of the second fencing in the second slot.
In yet another embodiment, the plate can include a third edge extending between the first and second edges generally parallel to the slot and a fourth edge opposite the third edge. The fourth edge can define a laterally projecting tongue. The tongue can include at least one opening to receive a fastener. The fastener can penetrate the tongue to secure the plate to a fence post. Optionally, the fastener can also penetrate a second tongue of a second plate to secure both plates to a fence post at a single location.
In any of the embodiments, each of the first and second edges of the plate can include a rearwardly projecting flange. An end of the pin can include a bend of sufficient size to extend over a rear edge of the rearwardly projecting flange of one of the first and second edges while the opposite end is engaged in a bight of a bend in the fencing penetrating a slot in the plate. A feature of any of the embodiments is the presence of a pin engaged in a bight of a bend in the fencing penetrating a slot in the plate. An advantage of this feature is that the pin can be vertically removed from the bight to quickly release the fencing from the slot.
These and other features and advantages will become more readily apparent from the following detailed description of the presently described embodiments illustrated in the accompanying drawings.
A pin 38 has a lower end 40 and an upper end 42 separated from each other such that the pin 38 has a length which is greater than the distance between the upper end 26 and the lower end 28 of the slot 24. The pin 38 is shown to be inserted into the bight 32 in the fold 30 of the fencing 12. The upper end 42 of the pin 38 is shown to engage the first edge 20 of the plate 18 to retain the fold 30 of the fencing 12 in the slot 24. The first and second edges 20, 22 of the plate 18 are shown to include a rearwardly projecting flange 44, and 46, respectively. The upper end 42 of the pin 38 is shown to include a bend 48 of sufficient size to extend over a rear edge 50 of the rearwardly projecting flange 44 of the first edge 20 while the opposite end contacts the plate surface adjacent to the lower edge 22 and the pin 38 is engaged in the bight 32. The pin 38, and particularly the lower end 40 of the pin 38 is dimensioned such that the pin 38 can be removed vertically from the bight 32 to quickly release the fencing 12 from the slot 24.
