## Background
RELATED APPLICATIONS
This application claims the benefit of U.S. Provisional Application No. 61/950,465, which was filed Mar. 10, 2014, the entire disclosures of which are incorporated herein by reference.


FIELD OF THE INVENTION
The presently disclosed subject matter relates to installing fencing. More particularly, the present invention relates to a fence installation jig.
BACKGROUND OF THE INVENTION
There are many home improvement projects a home owner can undertake to update and beautify their homes. One (1) of the most popular and useful is fencing. A fence can enhances the aesthetic beauty of a home and its landscaping, serve as a boundary for children and pets, act as a deterrent for trespassers, and help maintain good relationships with neighbors.
Modern fencing takes many forms. Picket fences, chain link fences, wood fences, and vinyl fences are all widely available. Modern fencing provides home owners with a variety of styles, quality construction, and years of services with little or no maintenance. However, actually constructing a fence tends to be time consuming and is very labor intensive. For example, vinyl fences are usually constructed of vinyl fence panels that are attacked to fence posts. In the prior art constructing a vinyl fence required one to carefully measure and then re-measure a cut before actually making that cut. A mistake was costly both in time and materials. Additionally, in the prior art it was often difficult to determine accurate locations where vinyl fence connectors needed to be located when attaching each panel. Wood privacy fences had similar problems.
In view of the foregoing there exists a need for a device that makes construction of vinyl and privacy fencing easier, faster, and simpler.
SUMMARY OF THE INVENTION
The principles of the present invention provide for a jig that makes construction of privacy fencing such as those made of vinyl and wood easier, faster, and simpler.
A fence jig that is in accord with the present invention includes an elongated board having a planar fence face and a planar post face opposite the fence face. A rip edge extends between the fence face and the post face and an outer edge is located opposite the rip edge. The board further includes a top edge and a bottom edge. The fence jig also includes a post guide that attached to the board top edge and which perpendicularly projects out the said post face to form an under face. A first flange is attached to the fence face. The first flange has a first flange board face in contact with the fence face, a first flange fence face opposite the first flange board face, a top edge above the first flange board face and the first flange fence face, a first flange rip edge on the left of the first flange board face; a first bracket upper edge opposite the top edge, and the thickness of a stringer of a fence being constructed.
The fence jig also includes a second flange attached to the fence face, the second flange having a second flange board face in contact with the fence face, a second flange fence face opposite the second flange board face, a first bracket lower edge above the second flange board face and the second flange fence face, a second flange rip edge to the left of the second flange board face; a second bracket upper edge opposite the first bracket lower edge, and the thickness of a stringer of a fence being constructed.
The Fence Jig also includes a third flange attached to the fence face. The third flange having a third flange board face in contact with the fence face, a third flange fence face opposite the third flange board face, a second bracket lower edge above the third flange board face and the third flange fence face, a third flange rip edge to the left of the third flange board face; and a second flange bottom edge opposite the second bracket lower edge, and the thickness of a stringer of a fence being constructed.
In practice, the post guide is placed on top of a fence post with the post face in contact with that fence post. Then the first bracket upper edge is located where the top of a “U”-shaped bracket should go.
In addition, the fence jig can include a first spacer that attached to the post face and to the under face to form a first reference edge, a second spacer attached to the post face to form second reference edge, and a third spacer attached to the post face to form a third reference edge such that the first reference edge, the second reference edge, and the third reference edge are coplanar.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
The preferred embodiment of the present invention is depicted within FIGS. 1-7. However, the invention is not limited to what is specifically illustrated and described. A person skilled in the art will appreciate that many other embodiments of the invention are possible without deviating from the basic concept of the invention. Any such work around also falls with the scope of this invention.
The terms “a” and “an” herein do not denote a limitation of quantity, but rather denote the presence of at least one of the referenced items. In addition, unless otherwise denoted all directional signals such as up, down, left, right, inside, outside are taken relative to the illustration shown in FIG. 1.
Referring now to FIGS. 1 and 5a-7, the present invention describes a fence jig 10 which aids in the installation of a privacy fence. That fence is fabricated from vinyl (or wood) fence panels 105 which are guided into place by the fence jig 10 when attaching a first “U”-shaped bracket 125 and a similar second “U”-shaped bracket 130 to a previously erected fence post 100. The fence jig 10 also acts as a guide when adjusting the width and/or height of the fence panels 105.
Referring now specifically to FIGS. 5a and 5b, each fence panel 105 is usually provided as a pre-fabricated structure that typically measures sixty eight inches (68 in.) in length and sixty eight inches (68 in.) in height. Each fence panel 105 is composed of twelve (12) individual pickets 115 that are attached together on both sides by two (2) stringers 110. To install the fence panel 105 the stringers 110 are attached to pre-installed fence posts 100 using panel fasteners 120 that are inserted into an upper first “U”-shaped bracket 125 and into a lower second “U”-shaped bracket 130. The fence posts 100 are preferably seventy two inches (72 in.) in height and will usually have some portion buried underground as required to meet applicable local building codes.
FIG. 1 presents a front elevation view, FIG. 2 presents a side elevation view, FIG. 3 presents a rear elevation view, and FIG. 4 presents an isometric view of the fence jig 10. The fence jig 10 includes a board 20 and a top post guide 30. The board 20 is the central part of the fence jig 10 to which other pieces are attached. The board 20 and the post guide 30 are preferably composed of wood or vinyl. Other materials, such as composite materials, other thermoplastics, and metal, may also be used. The board 20 is both flat and straight with straight edges. The board 20 is typically about seventy two inches (72 in.) long to correspond to the height of a fence post 100. The face showing in FIG. 1 is designated as the post face 22. The post face 22 is the face which is placed against a fence post 100 when the fence jig 10 is being used to attach fence panels 120. The face opposite the post face 22 is the fence face 24; specifically reference FIG. 3. The long edge on the left side of the board 20 as seen in FIG. 1 is the rip edge 28. The rip edge 28 acts as a guide for a power saw that is used to make cuts to a fence panel 105 when making width adjustments to fit the fence panel 105 to a fence post 100. The long edge opposite the outside edge 26 is the rip edge 28. The short edge at a bottom of the board 20 is the bottom edge 29.
The post guide 30 is a square piece that projects over the front of the board 20 (best shown in FIG. 5a). The post guide 30 is attached to the top of the board 20, preferably by adhesive and at least one (1) threaded fastener 16. The face of the post guide 30 in contact with the board 20 is the under face 34 while the upper face is the top face 32.
Referring again primarily to FIGS. 1-4, attached to the fence face 24 are a first flange 40, a second flange 50, and a third flange 60. Attachment is preferably made using adhesive and threaded fasteners 16; see FIG. 3. The first flange 40, the second flange 50, and the third flange 60 are preferably made of the same material as the board 20. In any event they have the same thickness as the stringers 110. The surface of the first flange 40 in direct contact with the fence face 24 is the first flange board face 42. The opposite surface of the first flange 40 is the first flange fence face 43. In use the first flange fence face 43 is placed against a fence panel 105 when using the fence jig 10. The narrow edge of the first flange 40 closest to the post guide 30 is the top edge 44. The narrow edge of the first flange 40 opposite that is the first bracket upper edge 46. The first bracket upper edge 46 contacts the top of the first “U”-shaped bracket 125 when fastening a first “U”-shaped bracket 125 to a fence post 100. The left side long edge of the first flange 40 is the first flange rip edge 48 (see FIG. 2). This first flange rip edge 48, along with corresponding edges on the second flange 50 and the third flange 60, acts as a guide for a power saw when making height adjustment cuts to fence panels 105 to make them properly fit between fence posts 100. The first flange 40 is attached to the board 20 at a location which places the first “U”-shaped bracket 125 at the correct height on the fence post 100 to engage the top stringers 110 of fence panels 105 when the post guide 20 is on top of a fence post 100 and the first bracket upper edge 46 is adjacent the upper surface of a first “U”-shaped bracket 125.
The second flange 50 has similar faces and long edges as the first flange 40. Specifically, a second flange board face 52, a second flange fence face 53, and a second flange rip edge 58. The third flange 60 is also configured similarly with a third flange board face 62, a third flange fence face 63, and a third flange rip edge 68. The upper narrow edge of the second flange 50 is the first bracket lower edge 54. The narrow edge of the second flange 50 is the second bracket upper edge 56. The length of the second flange 50 corresponds to the distance between the upper stringer 110 and the lower stringer 110 on the fence panel 105. The upper narrow edge of the third flange 60 is the second bracket lower edge 66. The edge opposite the second bracket lower edge 66 is the third flange bottom edge 69. The third flange 60 is attached to the bottom of the board 20. The length of the third flange 60 corresponds to the distance between a lower stringer 110 on a fence panel 105 and grade level.
Disposed on the post face 22 are a first spacer 70, a second spacer 80, and a third spacer 90. Each of the spacers 70, 80, 90 is about three inches (3 in.) high and two inches (2 in.) wide. The first spacer 70, the second spacer 80, and the third spacer 90 are attached to the board 20, preferably by adhesive and threaded fasteners 16. The upper surface of the first spacer 70 is attached to the under face 34 of the post guide 30. The left edge of the first spacer 70 is a first reference edge 76. The second spacer 80 is attached to the board 20 approximately two inches (2 in.) below the first spacer 70. The left edge of the second spacer 80 is a second reference edge 86. The third spacer 90 is attached to the board 20 approximately forty-one inches (41 in.) below the second spacer 80. The left edge of the third spacer 90 is a third reference edge 96. The first reference edge 76, the second reference edge 86, and the third reference edge 96 are coplanar and are used to align the rip edge 28 of the board 20 with the correct lateral location for a first “U”-shaped bracket 125 and a second “U”-shaped bracket 130 when the under face 34 of the post guide 30 is placed on top of a fence post 100 and the reference edges 76, 86, and 96 are in contact with fence post 100.
Refer now to FIG. 5a for an isometric view of the fence jig 10 on a fence post 100, to FIG. 5b for an isometric view of the fence jig 10 from another perspective, and to FIG. 3. In FIG. 5a the fence jig 10 is shown in use locating a first “U”-shaped bracket 125 at the correct location. The top guide 30 is placed on the top of the fence post 100 with the first spacer 70, second spacer 80, and the third spacer 90 flush against the fence post 100. When so arranged the first “U”-shaped bracket 125 is set in place by locating it on the inner face of the rip edge 28 between the first bracket upper edge 46 and the first bracket lower edge 54. The first “U”-shaped bracket 125 is then attached to the fence post 100 using one or more fasteners 120. A second “U”-shaped bracket 130 is then located on the fence post 100 by placing the second “U”-shaped bracket's “U”-shape against the inner face of the rip edge 28 between the second bracket upper edge 56 and the second bracket lower edge 66. The second “U”-shaped bracket 130 is then attached to the fence post 100 using one or more fasteners 120. Another first “U”-shaped bracket 125 and another second “U”-shaped bracket 130 can be located and attached to the opposite side of the post by moving the fence jig 10 to the opposite side and then repeating the process.
Refer now to FIG. 6 for an isometric view of the fence jig 10 used on a fence panel 105 and to FIG. 4 for details of the fence jig 10. During the installation of the fence the standard length of the fence panel 105 may exceed the distance between adjacent fence posts 100. In that case the fence panel 105 needs to be cut to fit. The fence jig 10 can assist this cutting. To do so the fence panel 105 is positioned on a stable horizontal work surface with the excess length overhanging the supports. The fence jig 10 is placed on the fence panel 105 with the fence face 24 in contact with the fence panel 105. The upper stringer 110 is between the first flange 40 and the second flange 50 and the lower stringer 110 is located between the second flange 50 and the third flange 60. The first flange board face 42, the second flange board face 52, and the third flange board face 62 are in the same plane as the exposed faces of the stringers 110 with the first flange rip edge 48, second flange rip edge 58 and third flange rip edge 68 aligned with the desired cut line on the fence panel 105. A saw is then run along the fence panel 105 using the rip edge 28 as a guide. The result is a clean, straight cut across the length of the fence panel 105. In practice the fence jig 10 may be clamped to the fence panel 105 to keep the fence jig 10 in place.
Refer now to FIG. 7 for an isometric view of the fence jig 10 on a fence panel 105 being used to adjust the height of a fence panel 105. In some applications the height of a fence panel 105 may need to be adjusted by cutting. The fence jig 10 assists this cutting. To do so the fence panel 105 is positioned on a stable horizontal work surface with the excess height overhanging the supports. The fence jig 10 is placed longitudinally on the fence panel 105 with the fence face 24 in contact with the fence panel 105. The fence jig 10 is then aligned with the desired cut line to allow the saw to cut the fence panel by being moved along the first flange rip edge 48, the second flange rip edge 58, and the third flange rip edge 68. In practice the fence jig 10 should be clamped to the fence panel 105 during cutting.
