This disclosure generally relates to fencing supports and parts for entering the ground, and more specifically to a folding corner assembly for efficient deployment of fence supports, specifically corner assemblies and endpoints.
It is commonly said that good fences make good neighbors, but fences can be time consuming to install, requiring much labor. Corner assemblies are one of the main structural elements of a fence. Corner assemblies are commonly made from eight-foot-tall posts having a diameter of eight-inches. Corner assemblies are built by digging holes for the end post and brace post in the ground. The direction that the fence travels requires a brace post (or second post) in addition to the end post. A horizontal brace is installed to form the H-brace corner assembly. A brace wire may connect the brace post to the end post. Installation of a corner assembly is laborious and time consuming, but important to the longevity and structural soundness of the fence.
We recognized that a fence post system having a folding corner assembly could be installed quicker, with fewer workers, and with fewer errors than traditional fence systems. Installation of existing fence end points is laborious and requires skill and experience. It may take someone unfamiliar with the construction of a fence corner three to five times longer to complete the task than an experienced worker. To become proficient generally may require the construction of 10-20 corners. Our fence system with folding corner assembly dramatically improves the user experience and produces a result that looks good even when lacking prior knowledge or skill. This fence system with folding corner assembly can work with two stranded barbed wire, two strand barbless wire, woven wire, welded wire, plastic fence materials, high tensile wire, Gaucho® barbed wire, cable materials, multi-strand materials, electric fence, and invisible fencing. Traditionally, building materials for corner or end posts such as posts, braces and wires are transported separately to a work site. The corner assembly is then assembled on site.
An advantage of the current disclosure is increased portability of the folding corner assembly compared with a traditional corner assembly. This allows the folding corner assembly to be easier to ship or transport. Reducing the per unit shipping volume—or alternatively, increasing the packing factor (number of units per shipping container)—has numerous advantages in a modern economy where the equipment is manufactured a long way away from the installation site. Being able to ship the folding corner assembly enables installation at remote locations, because shipping costs per unit are decreased when additional units can fit in a shipping container. For one example, a folding corner assembly—including two sleeves, a riser post, a stretch mechanism, a brace, and angle supports—is approximately the same size as an eight-foot-tall post having a diameter of eight-inches, which requires a second post and braces to be functional.
We also recognized that a sliding stretch mechanism provides the advantages of decreasing the time needed to initially stretch the wires and also allows easy maintenance. The stretch mechanism allows all five wires to behave as one unit. If there is a general loosening or tightening of wires, tightening of two or more tensioner bolts between the stretch mechanism and the support post will tighten all wires. This allows the operator to tighten all wires simultaneously rather than individually tightening each wire. Alternatively, one tensioner may be tightened more or less than a second tensioner to tighten or loosen a group of wires relative to an upper end and lower end of the stretch mechanism.
We also recognized that the folding corner assembly could be used on multiple soil types. Lower adapter “deadman plates” are positioned at a lower portion of the post sleeve of a first support, with larger adapter plates easily installed thereto for sandy or gravely soil. Default plate may have an 11″ diameter. A larger lower adapter plate may have a 15″ diameter for use in sandy or gravely soil.
“H Brace” corners can fail when proper tension is applied to the fence. The end post, sometimes referred to as the corner post, is held in the ground by its own weight and the friction between the portion of the post embedded in the ground and the surrounding soil. These forces are insufficient to counteract the horizontal pull of the wire. The most common solution is to add additional weight to the end post by increasing the diameter. Another way to increase weight is to set the end and brace posts in concrete. Each solution increases material and labor costs and increases the hazards of completing the job. According to the current disclosure, the lower plate (foot or “deadman plate”) uses the weight of the soil to prevent the corner assembly or endpoint from being lifted out of the ground. The flat distributed surface of the vertically oriented support plate prevents horizontal movement of the corner assembly or endpoint. Similarly, a vertically oriented support plate on the second post sleeve of the second support efficiently distributes the horizontal load. Another advantage of the current disclosure is that in existing fencing solutions it is important to tamp the substrate around the end and brace posts. This repacking of the soil may account for approximately one-third of the time to construct the most common industry corner. The foot or “deadman plate” of the current disclosure avoids the need to repack or “tamp” the soil in around the posts, saving labor and time. Once the end and brace assemblies are in the ground, the installer simply refills the hole.
Obtaining a proper tension based on stretching the wires is also important for proper fence installation. A stretch mechanism slides along the brace to stretch each of the wires simultaneously. Markings on the brace indicate different stretch specification levels. Printed or electronic user guides allow the installer to determine an appropriate stretch specification level based on the terrain type, soil substrate type, and fence run length.
Aspects are illustrated by way of example, and not by way of limitation, in the accompanying drawings, wherein:
The fence post system 100 has a deployed configuration 102, shown in
As shown in
A first post sleeve 140 is partially inserted into the ground and is configured to receive and support the first post riser 108. The first post sleeve 140 has a first lower sleeve portion 142 configured to be inserted into the ground and a first upper sleeve portion 144 that is maintained above the ground. A first deadman plate 146 optionally extends radially from the first lower sleeve portion 142. The first deadman plate 146 may have a first flat edge 148 with a notch 150. Additionally, the first deadman plate 146 may have a second flat edge opposite the notch 150 side of the deadman plate to aid in leveling and packaging of the folding corner assembly in the storage configuration 104. The first post sleeve 140 may have a rectangular or cylindrical cross section with a hollow center. Alternatively, the first post sleeve 140 may have a cross section complimentary to the cross section of the first post riser 108. The first post sleeve 140 has an upper opening 154 through which the first post riser 108 can be inserted into the hollow center of the first post sleeve 140. The first post sleeve 140 is configured to receive the first post riser 108 through the upper opening 154 and into the hollow center. A first-post-riser-sleeve-height pin slot 152 is disposed through the first upper sleeve portion 144.
The first post riser 108 of the first support 105 is configured to slide vertically within the first post sleeve 140 to adjust the height of the first post riser 108 above the ground. The first post riser 108 may have a longitudinal length of less than 72 inches. The first post riser 108 may be between 60 inches to 65 inches in length. The first post riser 108 is secured at a certain height by passing a first pin (not shown) through a selected one of the plurality of first-riser-height pin slots 128, 130, 132, 134, 136 and the first-post-riser-sleeve-height pin slot 152. The first pin secures the first post riser 108 at a given height. The height of the first post riser 108 may be set to varying heights depending on the terrain and the species or breed of animal to be contained within the fence.
A first brace bracket 160 is mounted to the first upper sleeve portion 144 in order to connect the first brace 170 to the first post sleeve 140. The first brace bracket 160 comprises a first brace bracket portion 156 extending perpendicular to the longitudinal axis of the first post sleeve 140 and a second brace bracket portion 158 mounted to the first brace bracket portion 156. The second brace bracket portion 158 extends parallel to the longitudinal axis of the first post sleeve 140. A first-bracket-pivot pin slot (not shown) is disposed through the second brace bracket portion 158. A first-bracket-storage pin slot 162 disposed in the second brace bracket portion 158 is longitudinally spaced apart from the first-bracket-pivot pin slot.
A first brace 170 is shown in
The first brace 170 as shown in
The first brace 170 is configured to be pivoted relative to the first post sleeve 140 of the first support 105 to the storage configuration 104 wherein the first brace 170 is parallel with the first post sleeve 140 and the first brace 170 is received into the notch 150 of the first deadman plate 146. The first brace 170 is also configured to be pivoted relative to the first post sleeve 140 of the first support 105 to the deployed configuration 102 wherein the first brace 170 forms an angle with the first post sleeve 140 between 20° to 160°.
The first brace 170 can be secured in the storage configuration 104 by passing a third pin 181 through the first-bracket-storage pin slot 162 and the first-brace-first-storage pin slot 174. Locking the first brace 170 to the first post sleeve 140 allows the folding corner assembly to be more easily transported by stacking the first brace 170 and the first post sleeve 140 in line with each other. The first post sleeve 140 may have a longitudinal length of approximately half of the longitudinal length of the first brace 170 to facilitate inline stacking with multiple post sleeves. In one example, the first post sleeve 140 is approximately 4 feet and the first brace 170 is approximately 8′ in length. The first post sleeve 140 may be less than 48″ in length. The first post sleeve 140 may be between 39″ to 42″ in length. The first brace 170 may be between 96″ to 144″ in length.
A second post sleeve 200 of the second support 205 may be configured to receive a second post riser (not shown). The second post sleeve 200 may have a rectangular or cylindrical cross section. The second post sleeve 200 has a second lower sleeve portion 202 configured to be inserted into the ground. The second post sleeve 200 has a second upper sleeve portion 204 configured to be installed above the ground. A load plate 220 is mounted to the second upper sleeve portion 204. The load plate 220 is shown having a first flat edge 222 and may have a first notch 224 in the first flat edge 222. The second post sleeve 200 has a longitudinal length of approximately half of the longitudinal length of the first brace 170, so that in the storage configuration 104 the first post sleeve 140 and the second post sleeve 200 can be pivoted parallel with the first brace 170. In one example, the second post sleeve 200 is approximately 4′ and the brace is approximately 8′ in length. The second post sleeve 200 may be less than 48″ in length. The second post sleeve 200 may be between 39″ to 42″ in length.
A second brace bracket 230 is mounted to the second upper sleeve portion 204. The first brace 170 is configured to be pivotally mounted to the second brace bracket 230 at the second end 176 of the first brace 170. The second brace bracket 230 comprises a third brace bracket portion 232 extending perpendicular to the longitudinal axis of the second post sleeve 200. A fourth brace bracket portion 234 is mounted to the third brace bracket portion 232 and extends parallel to the longitudinal axis of the second post sleeve 200. A second-bracket-pivot pin slot 236 is disposed in the second brace bracket 230 at the junction between the third brace bracket portion 232 and the fourth brace bracket portion 234. A second-bracket-storage pin slot 238 is disposed in the fourth brace bracket portion 234. The second-bracket-storage pin slot 238 is longitudinally spaced apart from the second-bracket-pivot pin slot 236.
By attaching the first brace 170 to the second-bracket-pivot pin slot 236, the first brace 170 can pivot relative to the second post sleeve 200 between the storage configuration 104 and the deployed configuration 102. In the storage configuration 104, the first brace 170 is parallel with the second post sleeve 200 and longitudinally aligned with the first post sleeve 140. The first brace 170 is configured to be secured in the storage configuration 104 by passing a fifth pin 281 through the second-bracket-storage pin slot 238 and the first-brace-second-storage pin slot 179. In the deployed configuration 102, the first brace 170 forms between a 20° to 160° angle with the second post sleeve 200.
An angle support 250 provides structural support for the first post riser 108 in the deployed configuration 102. The angle support 250 can be folded down into the storage configuration 104 where the angle support 250 is generally inline with the first brace 170. The angle support 250 has a first angle support end 252 and a second angle support end 254. A cross-brace-first-pivot pin slot 251 is disposed through the angle support 250 at the first angle support end 252. The angle support 250 is configured to pivot relative to the first brace 170 by passing a sixth pin 175 through the cross-brace-first-pivot pin slot 251 and the first-brace-cross-brace-pivot pin slot 171. A cross-brace-second-pivot pin slot 255 is disposed through the angle support 250 at the second angle support end 254. As shown in
Another fence system with folding corner assembly is shown in
The first post riser 550 is installed above ground, and above ground components may be powder coated. The first post riser and post sleeves may be made of cylinder pipe material made of metal having thickness between ½″ to ¼″. Using thicker material in the post sleeves and thinner material for the first post riser may shift the weight of the folding corner assembly towards a lower half of the assembly when installed. Not wanting to be bound to theory, the shifted weight may lower the center of gravity on the folding corner assembly to increase overall stability of the fence system. The first post riser 550 extends generally in a straight line from first post sleeve 300. An upper brace bracket 570 is shown mounted to the upper portion of first post riser 550. The upper brace bracket 570 comprises a first upper brace bracket portion 571 and a second upper brace bracket portion 572 extending perpendicular to the longitudinal axis of the first post riser 550. The first upper brace bracket portion 571 extends parallel to the longitudinal axis of the first brace 370. The second upper brace bracket portion 572 extends perpendicular to the longitudinal axis of the first brace 370. The first brace 370 extends generally perpendicular to the first post sleeve 300 as shown in
Similar to the first post sleeve 300, a second post sleeve 400 is mostly buried in the ground. A second deadman plate 440 is mounted to the lower portion of the second post sleeve 400. The second deadman plate 440 has a second deadman plate slot 444 to enable a compact storage configuration. The second deadman plate 440 may have a second flat edge on the other side of the post sleeve opposite the second deadman plate slot 444. The second post sleeve 400 also has a load plate 420. The load plate 420 is shown having a first flat edge 422 to aid in leveling and packaging of the folding corner assembly in the storage configuration 104. The load plate 420 is shown mounted to the second post sleeve 400 oriented in a plane tangential to the second post sleeve 400 and away from the first post sleeve 300. The second post sleeve 400 is inserted in to the second hole and buried to distribute the load once the fence wires are installed and tensioned.
A stretch mechanism 500 is mounted to the first brace 370 through a slide mechanism 510. The slide mechanism 510 is configured to guide movement of the stretch mechanism 500 along the longitudinal axis of the first brace 370. The stretch mechanism 500 extends generally perpendicularly from first brace 370. Alternatively, the stretch mechanism 500 can be mounted to the slide mechanism 510 using a slot and pin mechanism to enable installation on uneven or hilly terrain.
A first post riser 550 is installed into the first post sleeve 300. A first-post-riser-sleeve-height pin slot 352 is disposed through the first upper sleeve portion 344. The first post riser 550 is secured at a certain height by passing a first pin (not shown) through a selected one of the plurality of first-riser-height pin slots 328, 330 and the first-post-riser-sleeve-height pin slot 352 that is better illustrated in
Fence wires 612, 614, 616, 618, and 620 are connected to the stretch mechanism 500 through springs 602, 604, 606, 608, and 610. As shown more clearly in
The type of terrain for installation may affect the choice in the selected spring mechanism for the fence wire tensioning process. Individual springs may be attached to the individual fence wires for tensioning by the stretch mechanism 500 on hilly terrain. Flat terrain may allow for a single spring mechanism that cooperates with the stretch mechanism 500 for tensioning all fence wires together. Individual springs may be directly connected to the stretch mechanism 500 through the holes in the stretch mechanism 500. The springs may be connected to the stretch mechanism 500 via connectors inserted through the hole and secured to the stretch mechanism. Once the wires are run, the stretch mechanism 500 is slid along the first brace 370 to the chosen stretch position marking on the first brace 370. Tensioners are installed between the end post and the stretch mechanism 500 to secure the position of the stretch mechanism 500 relative to the end post. Guide notches may be disposed in the posts along the fence line to be stretched. When fence wires are pulled together in the installation of the fence system the guide notches may be used to maintain separation between individual fence wires. Guide notches may prevent tangling by the unstretched fence wires during the installation process.
In applications where the fence wires are electrified, rubber washers may insulate the springs 602, 604, 606, 608, 610 or connectors. Alternatively, the stretch mechanism 500 may comprise a composite material that is non-conductive, such as a pultrusion fiberglass. Alternatively, the stretch mechanism 500 may comprise a single spring mechanism that pulls the stretch mechanism 500 into position near the first post riser 550 for stretching the fence wires 612, 614, 616, 618, 620 into place.

A chart, diagram, or user guide may be provided with the folding corner assembly. The user guide is based on functions of fence installation terrain type, fence installation distance, climate at installation site, and properties of the fence wire such as a tensile strength factor. For example, an installer may use a guide based on stretch specification settings or ranges to reduce the amount of time spent in fence system tensioning. The guide may be based on equations related to yield strength of the fence wire where a stretch factor for the specific wire used is provided. The stretch factor may be based on a strain input value of the wire. The guide may direct the installer to stretch the fence wire to a designated stretch point. A stress string curve, based on wire properties, may be used in determining the stretch specification for marking placement of the final stretch point.
A fence system with a folding corner assembly can be installed with the following process. First a folding corner assembly is installed. A final stretch point specification may be based on a stretch distance calculation. One fence wire is stretched to the stretch specification marking on the brace. The stretched fence wire is used to establish a line for setting posts for the fence system. The stretch mechanism is unpinned. The remaining fence wires are pulled and connected to the stretch mechanism. The fence wires are pulled together to the stretch specification by the stretch mechanism.
To determine the appropriate stretch specification, the installer observes or records a variety of parameters including soil type, fence length, and terrain description. A printed guide or software application uses the fence installation location observations to calculate a recommended stretch specification. The recommended stretch specification corresponds to the plurality of markings 1601, 1602, 1603, 1604, 1605 on the brace 1600. The brace 1600 may have additional stretch specification markings. The plurality of markings are longitudinally spaced apart, on a longer or shorter sized brace. The user installs the fence wire to the stretch mechanism, as discussed above, and then stretches the fence wires by sliding the slide mechanism along the longitudinal axis of the brace via the slide mechanism. The user guide may define a start zone along the brace for a start push point. The user guide may also define an end zone along the brace for a final stretch point of the fence system. The start zone and end zone may correspond to the markings on the brace. The start zone may be variable based on the user guide, with the end zone being fixed. Alternatively, the end zone may be variable based on the user guide, with the start zone being fixed. Alternatively, both the end zone and the start zone may be variable based on the user guide. Alternatively, both the end zone and the start zone may be fixed based on the user guide. The distance the slide mechanism moves along the brace from the start push point to the final stretch point may be between 1′ to 8′ when stretching between an eighty to a quarter mile length of fence wire. Once the slide mechanism reaches the indicated marking on the brace, one or more tensioners are mounted between the post and the stretch mechanism to maintain the position of the stretch mechanism relative to the post. The tensioners may also be used for micro adjustment of the stretch mechanism or for releasing the stretch on the fence wires by the tightening or loosening of two or more tensioner bolts, respectively.
The chosen end zone (or final stretch point) may be determined based on a user guide as stated above. A software application, specifically an application installed on a mobile device having a Global Positioning System (GPS) or other position tracking sensors, may be used to automatically record and calculate the stretch specification. For example, the installer initializes a position recording feature. As the installer walks along the fence run, the software records the altitude changes and the length of the fence run. The software may determine the soil composition using location data accessed publicly or privately available through soil type maps. The software may prevent installer error in determining the stretch level specification. Alternatively, an application such as Google Earth may be used in determining a length of linear feet between a start peg and an end peg placement of the mapping application. Rough calculations may be based on use of the application in determining a quantity of materials needed and billed.
A stretch upgrade kit can be used to convert a traditional fence system. The stretch upgrade kit may include a marking bar. The marking bar has a plurality of markings indicating various stretch positions that may correspond to start zones and end zones, as may be indicated in a user guide. The marking bar may be freestanding. The marking bar may be mounted to a traditional fence attachment point, such as a first or second support post of a traditional fence start point, fence end point, H-brace corner assembly, or other corner post assembly. A sleeve may be incorporated on one end of the marking bar. The sleeve may receive the first support post. Alternatively, the marking bar may be attached to the first support post with fastening means used in traditional fence installations.
The stretch upgrade kit can also include a stretch mechanism. The stretch mechanism may be comprised of metal or plastic. The stretch mechanism may be a bar having a plurality of wire attachment points and a first tensioner attachment point. A plurality of fence wire types may be received and attached to the plurality of wire attachment points, as described above. The stretch mechanism may be configured to slide along a longitudinal axis of the marking bar with or without a slide mechanism. The marking bar guides positioning of the stretch mechanism from and to a chosen stretch specification (start zone to end zone, as described above).
The stretch upgrade kit can also include a first tensioner that secures the stretch mechanism to the traditional fence system, such as the first fence support post, the second support post, or both. The first tensioner may be constructed from a flexible material, rigid material, or a combination adjustably joined together. The first tensioner may be an acme screw, all thread rod, externally threaded bolt, tensioning rod or wire, linear actuator, or other bar having a length to span a distance between the stretch mechanism and the traditional fence attachment point. The first tensioner may be disposed through the first tensioner attachment point of the stretch mechanism.
The stretch mechanism may be secured to the first tensioner with a fastener such as a nut, wingnut, or other fastening means. The distance between the stretch mechanism and the traditional fence attachment point may be adjusted by tightening and loosening the fastening means upon the first tensioner.
The first tensioner, when positioned between the stretch mechanism and a second support post (“downstream” of the stretch mechanism), may be configured to push the stretch mechanism towards a first support post. Alternatively, the first tensioner, when positioned between the stretch mechanism and the first support post (“upstream” of the stretch mechanism), may be configured to pull the stretch mechanism towards the first support post.
The first tensioner is operated to push the stretch mechanism into the chosen stretch specification position based on the plurality of markings on the bar. As discussed above, a stress strain chart, a position tracking sensor, or a software application may be cross referenced to determine the stretch specification.
