Abstract

A fence pole cover is disclosed having two opposing connector panels disposed in angular relationship to one or more exterior panels. Edges exist on each of the unconnected ends of the connector panels. An edge gap extends between the edges. Applying force to the cover as against a fence pole bracket contracts the connector panel angles to store elastic potential energy in the cover while increasing the edge gap. Increasing the edge gap allows movement of the cover over a bracket width of the bracket, releasing restorative energy and expanding the angles. Release of all of the potential energy is prevented by engagement of the edges with intersections on the bracket. Residual elastic potential energy secures the cover to the fence pole bracket and fence assembly. In another embodiment, the cover attaches directly to the fence pole.

CROSS-REFERENCES TO RELATED APPLICATIONS

[0001] This application claims priority to Provisional Application No. 63 / 750,523 filed Jan. 28, 2025, and Provisional Application No. 63 / 850,390 filed Jul. 24, 2025.TECHNICAL FIELD

[0002] The present disclosure provides a visual shield to fence posts, brackets, and fasteners as are commonly used on wood fences.BACKGROUND INFORMATION

[0003] Fences provide security and privacy. It has been said that “good fences make good neighbors”. Some states have passed laws to prevent homeowners associations from preventing property owners from erecting fences for security. For example, in 2021, a state law was passed in Texas permitting homeowners in the state to put up a perimeter fence for added security along the front, sides and / or back of their property. However, Homeowners Associations (HOAs) are allowed to regulate the type of fencing and may prohibit, in some cases, fencing that crosses certain setback lines or is placed in front of the front-most building line of a house.

[0004] Residential, multifamily and commercial buildings utilize a variety of fence constructions. The most common is a wood fence mounted and supported by galvanized steel poles cemented into the ground. Commercially available brackets are clamped to the poles. Wood cross-members are horizontally mounted between the poles and connected to the brackets with fasteners. This comprises the backside of the fence. The more aesthetically pleasing front side of the fence comprises a continuum of vertical fence planks attached to the cross-members.

[0005] HOAs typically require fence poles to be placed on the inside of a property line to maintain a consistently better aesthetic appearance throughout the neighborhood. This ensures a uniform architectural culture for the neighborhood, which in turn enhances and preserves property values by preventing the visual clutter of the pole, brackets and cross-members being visible from the street. This further allows easier access for maintenance and repairs on the inside of the property by the owner of the fence. Having fence poles on the inside creates a much cleaner look from the street, where only a continuum of fence pickets are visible, providing a superior neighborhood aesthetic appearance.

[0006] Setting poles on the inside allows homeowners easier access to repair or replace fence sections without requiring access to the neighboring property.

[0007] A well-maintained and consistent appearance across the community can enhance curb appeal, protect property values, and attract potential buyers. However, as backyard property investments increase, the aesthetic value of the interior side of the fence increases as well. For this reason, many property owners build wood enclosures around the poles and brackets to conceal the hardware.

[0008] Fence poles are normally made of galvanized steel. Galvanized steel is standard steel that is coated in zinc to provide corrosion resistance. The galvanized protective coating protects the iron steel substrate from corrosion due to moisture, saturated environmental conditions, or ambient humidity.

[0009] The poles are cemented into holes. Although string trimmers cannot dent or cut the steel fence post, they impart sufficient force to remove the galvanized coating. With the galvanized coating compromised, the post is increasingly susceptible to corrosion that can permanently weaken the post over time. They will oxidize overtime in any event.

[0010] The most common size of galvanized round tubing used for fence post in residential areas is 2⅜ inch (2.625 inch) outer diameter (O.D.). The interior diameter (I.D.) varies with the thickness, known as the “gauge” of the post. The gauge of the post will normally be between 16 (0.065 inch thick) and 13 (0.095 inch thick). Gauge 15 is one of the most common (0.072 inch thick).

[0011] Examples of popular fence brackets include the Simpson Strong-Tie™ PGT2, and the OZCP Building Products™ WAP. These brackets are available for use with 2⅜ inch fence poles, and are widely available. The brackets are attached to wooden backer rails with threaded fasteners that are typically galvanized or zinc coated.

[0012] The poles also make for a ready grab bar for fence climbing, which is undesirable for security purposes. Despite the coatings, the brackets and fasteners will eventually oxidize and display rust. The brackets and fasteners are effective for fence construction, but along with the poles, they are strictly utilitarian, and unsightly.

[0013] The conventional solution is to construct wooden boxes around the poles, brackets, and fasteners. However, the solution is expensive, time consuming, and requires woodworking, tools, and additional fasteners for construction. This solution also requires the expertise to make and install the covers. This solution can also take a very long time to construct and install. This solution is also subject to damage from weather, insects, rodents, and routine lawn maintenance from string trimmers. This solution is also difficult and time consuming to remove and is unlikely to be reusable if the fence needs maintenance.

[0014] There is a need for an aesthetically pleasing fence pole cover that will conceal poles, brackets, and fasteners. There is also a need for a fence pole cover that can be installed efficiently. There is also a need for a fence pole cover that can be installed without the need for woodworking tools and expertise. There is also a need for a fence pole cover that is a deterrent to climbing. There is also a need for a fence cover that is removable and reusable. There is also a need for a fence cover that is durable, resistant to moisture, UV deterioration, oxidation, rodent habituation, insects, and weather. There is also a significant need for a fence cover that is aesthetically pleasing and more modern in appearance as compared to wood boxes.SUMMARY

[0015] As used herein, the terms “substantial” and “substantially” mean mostly.

[0016] An advantage of the disclosed embodiments is that they provide a device that solves the above-described problems. Another advantage of the disclosed embodiment is that it provides a much improved and uniform appearance to the back side of fences where brackets, fasteners and poles are visible, thus dramatically enhancing the appeal and value of the property.

[0017] Another advantage of the disclosed embodiments is that they provide a device that can be retrofit to existing fence poles without disassembly of the fence. Another advantage of the disclosed embodiments is that they provide a device that can be installed without tools, ladders, adhesives, or other implements.

[0018] Another advantage of the disclosed embodiments is that they provide a device that can be installed in seconds. Another advantage of the disclosed embodiments is that they provide a device that enhances security by concealing the pole and rendering it inaccessible for grabbing. This renders the fence significantly more difficult to climb.

[0019] Another advantage of the disclosed embodiments is that they provide a device that is durable, resistant to moisture, string trimmer damage, UV deterioration, rodent habituation, insects, and weather. Regarding rodents, the device eliminates the insulation, living space and open access common to wood pole covers, and its vertical metal interior cannot be scaled.

[0020] Another advantage of the disclosed embodiments is that they provide a manufacturing means that is efficient and cost effective.

[0021] In one embodiment, a fence pole cover is designed for connection to brackets attached to a fence pole. The brackets secure fence members (commonly horizontal wooden boards) to the pole. In one embodiment, a semi-circular cover panel is provided. In another embodiment, the cover comprises a plurality of two or more contiguous external panels. The external panels may be rectilinear. A right connector panel is disposed at an acute angle to an adjacent external panel. A connector radius is formed along the junction of the right connector panel and the adjacent external panel opposite the acute angle. A left connector panel is disposed at an acute angle to an adjacent external panel on the opposite side of the fence pole cover. Another connector radius is formed along the junction of the left connector panel and the adjacent external panel opposite the acute angle. An obtuse angle is formed between adjacent external panels.

[0022] The right connector panel has a right edge, which is the right inside edge of the cover. The left connector panel has a left edge, which is the left inside edge of the cover. An edge gap extends between the right edge and the left edge. The edge gap has a neutral length when no energy is stored when no external force is applied. Likewise, the connector angles, and any obtuse angles between external panels, have a neutral angle measurement when no energy is stored and no external force is applied to the cover.

[0023] An external force is applied to the cover in the direction of the fence pole. The right edge and the left edge engage the brackets attached to the fence pole. As the cover approaches the fence pole, the edge gap expands to an expanded length sufficient to permit installation of the cover over a portion of the bracket. The expanded length is equal to the bracket width, which is the structure forming the widest point on the front of the bracket beyond which the edge gap must pass.

[0024] The application of an external force against the cover in the direction of the fence pole causes the connector left edge and the connector right edge to increasingly engage the brackets on the fence pole. This results in contraction of the acute connector angles to a compressed angle, expansion of the obtuse angles between external panels, and expansion of the edge gap.

[0025] The edge gap reaches its expanded length when the connector left edge and connector right edge are at the bracket width. At the bracket width, the connector angles are compressed to their compressed angle.

[0026] Obtuse angles between other external panels may also be expanded. Expansion of the obtuse angles, and expansion or contraction of the acute angles, will store elastic potential energy in the cover. Panels of the cover may also be deflected, which will store elastic potential energy in the cover as well.

[0027] Coincident with continued movement of the right edge, left edge, and their associated edge gap past the bracket width of the bracket, the edge gap retracts from the expanded length to a latched length. The latched length is less than the expanded length and greater than the neutral length. The retraction may be substantially instantaneous, accompanied by a rapid movement of the cover in the direction of the pole.

[0028] Coincident with continued movement of the right edge, left edge, and edge gap past the bracket width of the bracket, the connector angles are expanded from their compressed angle to a latched angle. In one preferred embodiment, the latched connector angle is greater than the compressed angle, and greater than the neutral angle. In this embodiment, the cover has potential energy stored that urges the cover in the direction of the pole.

[0029] Movement in the direction of the fence is terminated by engagement of the left and right connector radii with a fence backer rail, to which the brackets are connected. Movement away from the fence is prevented by the left and right connector edges being located on the fence side of the loop in the latched position, resisting reversal of their direction of travel. This trapped engagement prevents connector angles from returning to their neutral angle positions. Additional elastic energy may also be stored in the obtuse angles between external panels. The residual elastic energy in the cover secures it in place with opposing forces acting against the fence pole brackets and the fence backer rails.

[0030] In another embodiment, the cover is made of galvanized steel having a thickness of 20 to 22 gage, and the edge gap is between 1.5 and 2 inches. In another embodiment, a powder coating is layered over the galvanized surface of the cover.

[0031] In an alternative embodiment, a fence pole cover is disclosed by which the connector panel left edge and right edge do not engage the bracket, but engage the pole directly. This embodiment is useful when installing the cover on a fence with an incompatible bracket design. This embodiment is also useful when installing the cover on a corner pole.

[0032] In this embodiment, the connector right edge and connector left edge each have a plurality of bracket reliefs that permit installation of the cover on the pole without engagement with the brackets. The bracket reliefs are located in the most common positions of brackets. The number and length of the bracket reliefs may vary with the length of the pole cover as longer poles may have more brackets attached to one or more an additional backer rails.

[0033] In this embodiment, an external force is applied to the cover in the direction of the fence pole. The right edge and the left edge engage the fence pole. As the cover approaches the fence pole, the edge gap expands to an expanded length sufficient to permit installation of the cover over the pole. The expanded length is equal to the pole diameter.

[0034] Coincident with continued movement of the right edge, left edge, and their associated edge gap past the pole diameter, the edge gap retracts from the expanded length to a latched length. The latched length is less than the expanded length and greater than the neutral length.

[0035] Coincident with continued movement of the right edge, left edge, and edge gap past the pole diameter, the connector angles are expanded from their compressed angle to a latched angle. In one preferred embodiment, the latched angle is greater than the compressed angle, and greater than the neutral angle. In this embodiment the cover has potential energy stored that urges the cover in the direction of the pole.

[0036] Movement in the direction of the fence is terminated by engagement of the connector radii of the left and right connectors with a fence backer rail, which is connected to the brackets. Movement away from the fence is prevented by the left and right connector edges being located on the fence side of the pole diameter in the latched position, resisting reversal of their direction of travel. This trapped engagement prevents connector angles from returning to their neutral angle positions. Additional elastic energy may also be stored in the obtuse angles between external panels. The residual elastic energy in the cover secures it in place with opposing forces acting against the fence pole and the fence backer rails.

[0037] In another embodiment, a fence pole cover is disclosed, having a right front panel contiguous with a left front panel. A right side panel is contiguous with the right front panel. A right connector panel is contiguous with the right side panel. A left side panel is contiguous with the left front panel. A left connector panel is contiguous with the left side panel. An edge gap extends between the right connector panel and the left connector panel. The edge gap is less than the length of the bracket width of a bracket attached to the fence pole to which the cover can be attached. In another embodiment, the edge gap is less than a diameter of a fence pole to which the cover can be attached.

[0038] In another embodiment, the right front panel is disposed at a front angle relative to the left front panel. The right side panel is disposed at a side angle relative to the right front panel. The right connector panel is disposed at a connector angle relative to the right side panel. The left side panel is disposed at the side angle relative to the left front panel. The left connector panel is disposed at the connector angle relative to the left side panel.

[0039] In another embodiment, expansion of the front angle and side angles and compression of the connector angles expands the edge gap to permit installation of the cover onto a bracket attached to a fence pole. In another embodiment, expansion of the front angle and side angles and compression of the connector angles expands the edge gap to permit installation of the cover onto a fence pole.

[0040] In another embodiment, the expansion of the front angle and side angles and compression of the connector angles stores initial elastic potential energy in the cover.

[0041] In another embodiment, upon placement of the cover on a fence pole bracket, the left connector panel and the right connector panel are placed in compression between a fence backer rail and a bracket attached to the backer rail and the fence pole.

[0042] In another embodiment, upon placement of the cover on a fence pole, the left connector panel and the right connector panel are placed in compression between a fence backer rail and the covered fence pole.

[0043] In another embodiment, the right front panel, right side panel, right connector panel, left front panel, left side panel, and left connector panel are rectilinear panels of the same length.

[0044] In another embodiment, the right side panel and left side panel are wider than the right connector panel and left connector panel, and the right connector panel and left connector panel are wider than the right front panel and left front panel.BRIEF DESCRIPTION OF THE DRAWINGS

Thus, the disclosed device is not intended to be limited to the embodiments shown, but is to be accorded the widest scope consistent with the principles and features disclosed herein.

[0075] It will be understood that certain elements of one disclosed embodiment may be included (or excluded) from another embodiment in accordance with the claims, and without departing from the knowledge of the embodiment disclosed herein.

[0076] FIG. 1 is an isometric view of a widely used PGT fence pole bracket 20 manufactured by Simpson Strong-Tie. Bracket 20 has a pair of opposing flanges 22. As best seen in FIG. 4, each flange 22 has a pair of fastener openings 24 for securing bracket 20 to a backer rail 52 of a fence assembly 1. A spacer 28 extends substantially perpendicular from each flange 22. Spacers 28 are connected by a loop 36. A latch width 30 defines the distance between the outsides surfaces of spacers 22. A loop riser 38 may extend from each side of loop 36 proximate to the diameter of loop 36, and circumferentially towards spacers 28. A tensioning faster 34 is provided for securing bracket 20 to a fence pole 4 as best seen in FIG. 4. As seen in FIG. 9, a bracket width 40 defines the widest distance between points on loop risers 38. As best seen in FIGS. 10 and 11, an intersection 42 is formed at the junction of loop 36 and each spacer 28.

[0077] FIG. 2 is an isometric view of a widely used WAP fence pole bracket 60 manufactured by OZCO Building Materials. Bracket 60 has a base 62. Base 62 has a plurality of fastener openings 64 for receiving fence connecting fasteners for securing bracket 60 to a backer rail 52 of a fence assembly 1.

[0078] A pair of inner flanges 66 extend outward from and substantially parallel to base 62. Each inner flange 66 has a tensioner opening 72 for receiving a tensioning fastener 74. A strap 76 has a semi-circular form with an outer flange 78 of each end. The semi-circular form of strap 76 permits complementary fit against a fence pole 4. Each outer flange 78 has tensioner openings 72 aligned with tensioner openings 72 on inner flange 66 for jointly receiving tensioning fasteners 74 for securing bracket 60 to a fence pole 4 of a fence assembly 1.

[0079] A bracket width 80 is the maximum length of strap 76, as measured between the ends of outer flanges 78 of strap 76, which is on the front portion of bracket 60. As best seen in FIGS. 17 and 18, a pair of intersections 82 are formed at the junction of the outermost point on each tensioning fastener 74, where tensioning fastener 74 meets the inside surface of outer flange 78. The distance between intersections 82 forms a latch width 70, which distance is shown in FIG. 2 displaced to the end of tensioning fasteners 74 for visibility of its length in FIG. 2. Latch width 70 is immediately rearward of bracket width 80, on the back side of strap 76.

[0080] FIG. 3 is an isometric view of a conventional fence assembly 1 with an embodiment of a cover 100 of the present invention attached to one of the several poles 4. As conventionally assembled, fence assemblies include poles 4, typically evenly spaced apart from 6 to 10 feet. Multiple brackets 20 are located on each pole 4. Backer rails 52 are connected to brackets 20 to horizontally span the distance between poles 4. Backer rails 52 provide a structure for attaching wood fence pickets 54 (not shown). Fence pole cover 100 is illustrated in position to cover and conceal poles 4 and brackets 20 connected to backer rails 52 beneath and behind fence pole cover 100. Cover 100 has a length 102 that will vary for compatibility with the length of pole 4 to be covered.

[0081] FIG. 4 is a close-up isometric view of certain components of fence assembly 1. As seen in FIG. 4, poles 4 have a cylindrical exterior 6 and a cylindrical hollow interior 8. Poles 4 have an open top 10. Bracket 20 is comprised of a pair of opposing flanges 22, a pair of spacers 28, and a loop 36 that extends between spacers 28 for surrounding pole 4. A tensioner hole 32 (see FIG. 8) extends through spacers 28 for receiving tensioning fastener 34 (not shown) for securing bracket 20 to pole 4.

[0082] Flanges 22 have fastener openings 24 for receiving fence connectors 26 (not shown) for attaching brackets 20 to backer rails 52. In this manner, backer rails 52 are securely suspended between poles 4. So assembled, backer rails 52 are receivable of pickets 54 (not shown) for attachment on the opposite side of backer rails 52 from poles 4 and brackets 20.

[0083] FIG. 5 is a close-up isometric view of an embodiment of cover 100 of the present invention attached to a fence pole 4 at brackets 20. As best seen in FIG. 3, this embodiment of cover 100 comprises a series of rectilinear panels extending the length 102 of cover 100. As seen in FIG. 5, cover 100 comprises a series of external panels 138.

[0084] The disclosed embodiment of external panels 138 is described herein as comprised of a right front panel 104, a left front panel 106, a right side panel 110, and a left side panel 112. Right side panel 110 extends from right front panel 104 to backer rails 52. At backer rail 52, right side panel 110 is connected to right connector panel 116 at an acute angle and thereafter extends inward. Right connector panel 116 forms the right-most panel of cover 100.

[0085] Left front panel 106 is connected to right front panel 104. Left side panel 112 extends from left front panel 106 to backer rails 52. At backer rail 52, left side panel 112 is connected to left connector panel 118 at an acute angle and thereafter extends inward. Left connector panel 118 forms the left-most panel of cover 100. Front panels 104 and 106 and side panels 110 and 112 comprise the external panels 138 and are the panels that conceal pole 4, brackets 20 and fasteners 26 and 34 from view.

[0086] FIG. 6 is a top view of the embodiment of FIG. 5, illustrating certain elements and angular relationships relative to that embodiment. Right front panel 104 and left front panel 106 are disposed at an obtuse angle 108 at a frontal bend 180. Right front panel 104 and right side panel 110 are disposed at an obtuse angle 114 at a right side bend 182. Similarly, left front panel 106 and left side panel 112 are disposed at the same obtuse angle 114 at a left side bend 184.

[0087] Right side panel 110 and right connector panel 116 are disposed at an acute angle 120 at a right corner bend 186. Similarly, left side panel 112 and left connector panel 118 are disposed at the same acute angle 120 at a left corner bend 188. A right edge 122 is formed at the terminus of right connector panel 116. A left edge 124 is formed at the terminus of left connector panel 118. An edge gap 126 is formed between right edge 122 and left edge 124.

[0088] As described, the present detailed embodiment of cover 100 comprises four panels 104, 106, 110, and 112 disposed at obtuse angles 108, 114 about three bends (180, 182, 184). Cover 100 further comprises two connector panels (116, 118) disposed at acute angles 120 about two bends (186, 188).

[0089] As seen in FIG. 7, but for edge gap 126, cover 100 would be in the form of an irregular concave polygon.

[0090] FIG. 7 is a close-up isometric view of the embodiment of cover 100 from FIG. 5, shown attached to fence pole 4. FIG. 6 illustrates the essential relationship between cover 100, brackets 20, and backer rails 52 in this embodiment. As seen in FIGS. 7 and 10 when installed, right edge 122 of right connector panel 116 and left edge 124 of left connector panel 118 engage bracket 20 proximate to intersections 42 of loop 36 and spacer 28 on bracket 20.

[0091] FIGS. 8-11 illustrate the installation process of the first embodiment in which the connector panels 116 and 118 engage brackets 20 on pole 4 for installation and to secure cover 100 to a fence assembly 1. The sequence refers to four positions of cover 100 and various dispositions of select elements during installation with the subscripts (a), (b), (c), and (d).

[0092] The descriptions below describe one embodiment of the installation procedure of cover 100. The illustrated and intermediate positions of cover 100 will vary depending on the details of the selected design such as the number of panels, material used and material strength, and relative width of the panels and the angles between them. However, the elastic energy principles for connection and concealing a fence pole and brackets remain the same.

[0093] FIG. 8 illustrates a top view of a first embodiment of cover 100(a) position, which is a neutral position (a), with no forces acting upon it and no energy stored therein. Cover 100(a) position represents cover 100 before installation. In this energy neutral position, right front panel 104 and left front panel 106 are disposed at an obtuse angle 108(a). Right front panel 104 and right side panel 110 are disposed at an obtuse angle 114(a). Similarly, left front panel 106 and left side panel 112 are disposed at the same obtuse angle 114(a).

[0094] Right side panel 110 and right connector panel 116 are disposed at an acute connector angle 120(a) inside a connector radius 128. Similarly, left side panel 112 and left connector panel 118 are disposed at the same acute connector angle 120(a) inside a connector radius 128. Right edge 122 is formed at the terminus of right connector panel 116. Left edge 124 is formed at the terminus of left connector panel 118. An edge gap 126(a) is formed between right edge 122 and left edge 124.

[0095] FIG. 9 illustrates a top view of a second cover position 100(b) in which cover 100 is under installation force to an expanded edge gap 126(b) to its maximum expansion necessary for installation over bracket width 40 of pole 4. When cover 100 is pressed in the direction of fence assembly 1, right edge 122 of right connector panel 116 and left edge 124 of left connector panel 118 engage loop 36. Continued application of force in the direction of pole 4 causes the expansion of edge gap 126(b) over circular loop 36 and loop risers 38 as cover 100 approaches position 100(c).

[0096] Expansion of edge gap 126(a) to 126(b) is achieved by the collective expansion of obtuse angles 108(b) and 114(b), and by contraction of acute connector angles 120(b). The work is performed by applying a force on cover 100 in the direction of pole 4. Elastic potential energy is accumulated in cover 100 from the expansion of angles 108(b) and 114(b) and contraction of acute connector angles 120(b) as edge gap 126(b) expands sufficiently to equal bracket width 40, which is the widest cross-section of loop 36. If bracket 20 has a loop riser 38, this is likely to be where bracket width 40 occurs.

[0097] FIG. 10 illustrates a top view of a third cover position 100(c) in the installation of cover 100, in which cover 100 is pressed beyond the contact of the second position (b) described above.

[0098] As cover 100 is pressed further in the direction of fence assembly 1, right edge 122 of right connector panel 116 and left edge 124 of left connector panel 118 move past bracket width 40 and loop 36 towards spacer 28. As they do so, edge gap 126(c) is released from interference with loop 36 and restorative energy in cover 100 urges the geometry of cover 100 towards its neutral state, reducing edge gap 126 to edge gap 126(c) length. This movement of cover 100 may be very rapid.

[0099] In a preferred embodiment, as movement of cover 100 continues further towards position 100(c), connector radii 128 engage backer rails 52. This embodiment eliminates any gap between backer rails 52 and cover 100 to provide a beneficial appearance of fit.

[0100] Movement of cover 100 may continue for a distance equal to a cover offset 130, which is best seen in FIG. 11. At that point, right front panel 104 may contact loop 36 at tangent point 132 and left front panel 106 may contact loop 36 at a tangent point 134. As seen in FIG. 10, contact between cover 100 and loop 36 prevents any further movement of cover 100 in the direction of fence assembly 1.

[0101] At cover 100(c) position, some or all of the energy stored in connector angles 120(c) has been released and connector angles 120(c) have returned to, or near to, or even passed, their neutral connector angle 120(a). However, side angles 114(c) and front angle 108(c) are now at their maximum expansion and storing their maximum energy. This is reflected in the maximum outward extension of connector radii 128 (c) against backer rail 52.

[0102] FIG. 11 illustrates a top view of the fourth and final cover 100(d) position in the installation of the bracket 20 engaging embodiment, with cover 100 fully installed against fence assembly 1. In this configuration, cover 100 is held securely in place on fence assembly 1.

[0103] When cover 100 is in position cover 100(d), the external force used for installation has been removed. With the force removed, elastic potential energy stored in cover 100 urges front angle 108(c), side angles 114(c), and connector angles 120(c) in the direction of their neutral positions (a). Cover 100 is prevented from fully returning to position 100(a) by engagement of connector edges 122 and 124 with intersections 42. Cover 100 may further be prevented from fully returning to position 100(a) by engagement of connector radii 128 with backer rails 52. Connector angles 120(d) retain elastic potential energy that draws cover 100 against backer rails 52.

[0104] Front angle 108(c) contracts to front angle 108(d). Side angles 114(c) contract to side angle 114(d), and connector angles 120(c) contract to connector angles 120(d). By these movements, edge gap 126(c) is reduced to edge gap 126(d) where further contraction is prohibited by interference with intersection 42.

[0105] Additional potential energy remains may be stored in cover 100 by deflection of connector panels 116 and 118, as well as external panels 138. Additional potential energy may be stored in cover 100 if front angle 108(d) and side angles 114(d) are greater than neutral front angle 108(a) and side angles 114(a).

[0106] FIG. 12 is a comparison of cover 100 positions of expansion and compression of the five panels angles 108, 114 (x2), and 120 (x2), and the movements and engagements of right edge 122, left edge 124, and connector radii 128, before, during, and after installation.

[0107] The distance between right edge 122 and left edge 124 are illustrated as edge gaps 126 in positions (a), (b), (c), and (d). FIG. 12 illustrates the movement of cover 100 as it is installed onto bracket 20 and against backer rail 52. The table below indicates the increase or decrease in angles (108, 114, 120) and of edge gap 126 as compared to the previous position, beginning with the unenergized, neutral state of cover 100.TABLE 1PositionAngle 108Angle 114Angle 120Gap 126a————b>><>c>>><d<<<<

[0108] A person of ordinary skill in the art will recognize that there may also be deflection in panels 104, 106, 110, 112, 116, and 118. Panel deflection will also store elastic potential energy. The amount of deflection will be a function of many factors such as the number of panels, material used and material strength, and relative width of the panels and the angles between them, length 102 of cover 100, number of brackets 40 per pole 4, frictional forces between right edge 122 and left edge 124 as against loop 36, and the amount of expansion of edge gap 126 required for installation. These variables may cause differences in the positions described above.

[0109] As described, in this first embodiment, cover 100 requires a degree of material elasticity to allow installation on brackets 20 of pole 4. Steel of 20-22 gage thickness has been modeled and tested for this purpose and found to bend sufficiently under 40 lbs. of force to allow installation. This has been determined to be within the range necessary to permit installation under the force that an average adult can exert, and yet be sufficiently secure as to retain its position under extreme wind conditions.

[0110] As disclosed and described, cover 100 may be installed by applying force to cover 100 in the direction of pole 4. This allows installation of cover 100 on existing fence assemblies 1 without the necessity of removal of fence top rails, and also avoids the difficulty of lifting cover 100 above pole 4 for installation. It also provides an installation that requires no tools or fasteners. It also provides a rapid installation. As installed, cover 100 conceals pole 4, brackets 20, fence connectors 26, and tension fasteners 34. The result is a dramatically improved aesthetic appeal, and the appearance of a strongly fortified fence. It further provides a deterrent to climbing the fence, as the easily held pole is concealed.

[0111] If cover 100 is made of a metal such as steel, it has the further benefits of being impervious to damage from string trimmers, UV light, changes in temperature, insects, and moisture. Significantly, the design is highly resistant to rodent habitation by depriving them of the access, insulation, living space, and climbable surfaces that are provided by wooden box pole covers. In particular, as seen in FIG. 11, the installed position of connector panels 116 and 118 and exterior panels 138 in relation to pole 4 inscribes a thermally conductive interior of metal that rodents cannot easily access because the space between connector edges 122 and 124 and pole 4 is no greater than the thickness of bracket 20. If accessed from below, they cannot climb the vertical metal walls. Most importantly, the lack of insulating surfaces eliminates the primary attraction of the space that wooden box covers provide.

[0112] In the illustrated embodiment above, cover 100 comprises four external panels 138. It will be readily understood by a person of ordinary skill in the art that more or fewer external panels 138 may be elected for use to obtain a different aesthetic effect, but the dynamics of the installation and elastic potential energy retention of cover 100 are the same or equivalent to those disclosed herein.

[0113] FIG. 13 is a top view of a second embodiment of cover 200 adapted for attachment to the OZCO Building Products bracket illustrated in FIG. 2, disclosing certain angular relationships relative to that embodiment.

[0114] A right front panel 204 and a left front panel 206 are disposed at an obtuse angle 208 at a frontal bend 280. Right front panel 204 and a right side panel 210 are disposed at an obtuse angle 214 at a right side bend 282. Similarly, left front panel 206 and left side panel 212 are disposed at the same obtuse angle 214 at a left side bend 284. As seen in FIG. 14, right front panel 204, right side panel 210, left front panel 206 and left side panel 212 collectively form external panels 238 of cover 200.

[0115] Right side panel 210 and a right connector panel 216 are disposed at an acute angle 220 at a right corner bend 286. Similarly, left side panel 212 and a left connector panel 218 are disposed at the same acute angle 220 at a left corner bend 288. A right edge 222 is formed at the terminus of right connector panel 216. A left edge 224 is formed at the terminus of left connector panel 218. An edge gap 226 is formed between right edge 222 and left edge 224.

[0116] As seen in FIG. 13, but for edge gap 226, cover 200 would be in the form of an irregular concave polygon.

[0117] FIG. 14 is a close-up isometric view of the embodiment of cover 200 from FIG. 13, shown attached to fence pole 4. FIG. 14 illustrates the essential relationship between cover 200, brackets 60, and backer rails 52 in this second embodiment. As seen in FIG. 14, when installed, right edge 222 of right connector panel 216 and left edge 224 of left connector panel 218 engage the junction of tensioning fasteners 74 and outer flange 78 of strap 76. As best seen in FIGS. 17 and 18, this junction is defined as intersection 82.

[0118] FIGS. 15-18 illustrate the installation process of the second embodiment in which the connector panels 216 and 218 engage brackets 60 on pole 4 to secure cover 200 to fence 50 (not shown). The sequence refers to four positions of cover 200 and various dispositions of select elements during installation with the subscripts (a), (b), (c), and (d).

[0119] The descriptions below describe one embodiment of the installation procedure of cover 200. The illustrated and intermediate positions of cover 200 will vary depending on the details of the selected design such as the number of panels, material used and material strength, and relative width of the panels and the angles between them. However, the elastic energy principles for connection and concealing a fence pole and brackets remain the same.

[0120] FIG. 15 illustrates a top view of an embodiment of cover 200(a) position, which is a neutral position (a), with no forces acting upon it and no energy stored therein. Cover 200(a) position represents cover 200 before installation. In this energy neutral position, right front panel 204 and left front panel 206 are disposed at an obtuse angle 208(a). Right front panel 204 and right side panel 210 are disposed at an obtuse angle 214(a). Similarly, left front panel 206 and left side panel 212 are disposed at the same obtuse angle 214(a).

[0121] Right side panel 210 and right connector panel 216 are disposed at an acute connector angle 220(a) inside connector radius 228. Similarly, left side panel 212 and left connector panel 218 are disposed at the same acute connector angle 220(a) inside connector radius 228. Right edge 222 is formed at the terminus of right connector panel 216. Left edge 224 is formed at the terminus of left connector panel 218. An edge gap 226(a) is formed between right edge 222 and left edge 224.

[0122] FIG. 16 illustrates a top view of a second cover position 200(b) during which cover 200 is under installation force to expanded edge gap 226(b) to its maximum expansion necessary for installation over strap 76. When cover 200 is pressed in the direction of fence assembly 1, right edge 222 of right connector panel 216 and left edge 224 of left connector panel 218 separate further until they engage the opposite ends of outer flanges 78 at a distance equal to bracket width 80. Continued application of force in the direction of pole 4 will cause edge gap 226(b) to move past strap 76 as cover 200 approaches position 200(c).

[0123] Expansion of edge gap 226(a) to 226(b) is achieved by the collective expansion of obtuse angles 208(b) and 214(b), and by contraction of acute connector angles 220(b). The work is performed by applying force to cover 200 in the direction of pole 4. Elastic potential energy is accumulated in cover 200 from the expansion of angles 208(b) and 214(b) and contraction of acute connector angles 220(b) as edge gap 226(b) expands sufficiently to equal bracket width 80.

[0124] A person of ordinary skill in the art will recognize that there may also be deflection in panels 204, 206, 210, 212, 216, and 218. Panel deflection will also store elastic potential energy. The amount of deflection will be a function of many factors including at least the number of external panels 238, material choice, thickness of cover 200 material, length 202 of cover 200, number of brackets 40 per pole 4, frictional forces between right edge222 and left edge 224 as against outer flanges 78 and possibly tensioning fasteners 74, and the amount of expansion of edge gap 220 required for installation.

[0125] FIG. 17 illustrates a top view of a third cover position 200(c) in the installation of the bracket 60 engaging embodiment of cover 200, in which cover 200 is pressed beyond the contact of the second position (b) described above.

[0126] As cover 200 is pressed further in the direction of fence assembly 1, right edge 222 of right connector panel 216 and left edge 224 of left connector panel 218 move past bracket width 80 and strap 76 towards base 62. As they do so, edge gap 226(c) is released from interference with strap 76 and restorative energy in cover 200 urges the geometry of cover 200 towards its neutral state, reducing edge gap 226 to edge gap 226(c) length. This movement of cover 200 may be very rapid.

[0127] In a preferred embodiment, as movement of cover 200 continues further towards position 200(c), connector radii 228 engage backer rails 52. This embodiment eliminates any gap between backer rails 52 and cover 200 to provide a beneficial appearance of fit.

[0128] At cover 200(c) position, some or all of the energy stored in connector angles 220(c) has been released and connector angles 220(c) have returned to, or near to, or even passed their neutral connector angle 220(a). However, side angles 214(c) and front angle 208(c) are now at their maximum expansion and storing their maximum energy. This is reflected in outward extension of connector radii 228(c) against backer rail 52.

[0129] FIG. 18 illustrates a top view of the fourth and final cover 200(d) position in the installation of the bracket 60 engaging embodiment, with cover 200 fully installed against fence assembly 1. In this configuration, cover 200 is held securely in place on fence assembly 1.

[0130] When cover 200 is in position cover 200(d), the external force used for installation has been removed. With the force removed, elastic potential energy stored in cover 200 urges front angle 208(c), side angles 214(c), and connector angles 220(c) in the direction of their neutral positions (a). Cover 200 is prevented from fully returning to position 200(a) by engagement of connector edges 222 and 224 with intersections 82. Cover 200 may further be prevented from fully returning to position 200(a) by engagement of connector radii 228 with backer rails 52. Connector angles 220(d) retain elastic potential energy that draws cover 200 against backer rails 52.

[0131] Front angle 208(c) contracts to front angle 208(d). Side angles 214(c) contract to side angle 214(d), and connector angles 220(c) contract to connector angles 220(d). By these movements, edge gap 226(c) is reduced to edge gap 226(d) where further contraction is prohibited by interference with intersection 82.

[0132] Additional potential energy remains may be stored in cover 200 by deflection of connector panels 216 and 218, as well as the external panels 238. Additional potential energy may be stored in cover 200 if front angle 208(d) and side angles 214(d) are greater than neutral front angle 208(a) and side angles 214(a).

[0133] FIG. 19 is a comparison of cover 200 positions of expansion and compression of the five panels angles 208, 214 (x2), and 220 (x2), and the movements and engagements of right edge 222, left edge 224, and connector radii 228, before, during, and after installation.

[0134] The distance between right edge 222 and left edge 224 are illustrated as edge gaps 226 in positions (a), (b), (c), and (d). FIG. 19 illustrates the movement of cover 200 as it is installed onto bracket 60 and against backer rail 52. The table below indicates the increase or decrease in angles (208, 214, 220) and of edge gap 226 as compared to the previous position, beginning with the unenergized, neutral state of cover 200.TABLE 2PositionAngle 208Angle 214Angle 220Gap 226a————b>><>c>>><d<<<<

[0135] A person of ordinary skill in the art will recognize that there may also be deflection in panels 204, 206, 210, 212, 216, and 218. Panel deflection will also store elastic potential energy. The amount of deflection will be a function of many factors such as the number of panels, material used and material strength, relative width of the panels and the angles between them, length 102 of cover 200, number of brackets 20 per pole 4, frictional forces between right edge 222 and left edge 224 as against strap 76, and the amount of expansion of edge gap 226 required for installation. These variables may cause differences in the positions described above.

[0136] In the illustrated embodiment above, cover 200 comprises four external panels 238. It will be readily understood by a person of ordinary skill in the art that more or fewer external panels 238 may be elected for use to obtain a different aesthetic effect, but the dynamics of the installation and elastic potential energy retention of cover 200 are the same or equivalent to those disclosed herein.

[0137] FIG. 20 is a rear close-up isometric view taken at a cross-section above a central backer rail 52 (shown transparently), illustrating a third embodiment in which a cover 300 is attached directly to fence pole 4, showing relationships relative to that embodiment.

[0138] In the illustrated embodiment, cover 300 comprises four external panels 304, 306, 308, 310, and 312. As seen in FIG. 21, front panels 304 and 306 are disposed at obtuse angles 308(a) and side panels 310 and 312 are disposed at obtuse angles 314(a) relative to contiguous front panels 304 and 306.

[0139] When installed as illustrated, right side panel 310 extends from right front panel 304 to backer rails 52. At backer rail 52, right side panel 310 is connected to a right connector panel 316 at an acute angle 320(a), and thereafter extends inward. Right connector panel 316 forms the right-most panel of cover 300.

[0140] Left front panel 306 is connected to right front panel 304. Left side panel 312 extends from left front panel 306 to backer rails 52. At backer rail 52, left side panel 312 is connected to a left connector panel 318 at acute angle 320(a) and thereafter extends inward. Left connector panel 318 forms the left-most panel of cover 300. Front panels 304 and 306 and side panels 310 and 312 comprise the external panels 338 and are the panels that conceal pole 4, brackets 20 and fasteners 26 and 34 from view.

[0141] A right edge 322 is formed at the terminus of right connector panel 316. A left edge 324 is formed at the terminus of left connector panel 318. An edge gap 326 is formed between right edge 322 and left edge 324. In FIG. 20, edge gap 326 is illustrated in the installed position “d” as 316(d).

[0142] As seen in FIG. 20, connector right edge 322 and connector left edge 324 each have a plurality of bracket reliefs 336 that permit installation of cover 300 on pole 4 without engagement with brackets 20 or 60. Bracket reliefs 336 are located in the most common positions of brackets 20 or 60, which is proximate to the location of backer rails 52. The number and length of the bracket reliefs 336 may vary with the length of pole cover 300 as longer poles 4 may have more brackets 20 or 60 attached to additional backer rails 52.

[0143] Cover 300 is advantageous for attachment to fence assembles 1 using alternatives to brackets 20 and 60. This embodiment is also advantageous for attachment to poles 4 positioned in corner positions, which also may have alternatives to brackets 20 and 60.

[0144] FIGS. 21-24 illustrate the installation process of this third embodiment in which connector panel edges 322 and 324 directly engage pole 4 for installation and to secure cover 300 to the fence assembly 1. The sequence refers to four positions of cover 100 and various dispositions of select elements during installation with the subscripts (a), (b), (c), and (d).

[0145] The descriptions below describe one embodiment of the installation procedure of cover 300. The illustrated and intermediate positions of cover 300 will vary depending on the details of the selected design such as the number of panels, material used and material strength, and relative width of the panels and the angles between them. However, the elastic energy principles for connection and concealing a fence pole and brackets remain the same.

[0146] FIG. 21 illustrates a top view of a cover 300(a) position, which is a neutral position (a), with no forces acting upon it and no energy stored therein, before installation. In this energy neutral position, right front panel 304 and left front panel 306 are disposed at an obtuse angle 308(a). Right front panel 304 and right side panel 310 are disposed at an obtuse angle 314(a). Similarly, left front panel 304 and left side panel 312 are disposed at the same obtuse angle 314(a).

[0147] Right side panel 310 and right connector panel 316 are disposed at an acute connector angle 320(a) inside a connector radius 328. Similarly, left side panel 312 and left connector panel 318 are disposed at the same acute connector angle 320(a) inside a connector radius 328. Right edge 322 is formed at the terminus of right connector panel 316. Left edge 324 is formed at the terminus of left connector panel 318. An edge gap 326(a) is formed between right edge 322 and left edge 324.

[0148] In the neutral position (a), left edge 324 and right edge 322 will contact pole 4, and avoid contact with brackets 20 or 60 by virtue of bracket reliefs 336. In this position, cover 300 is ready for installation. Installation requires imparting an external force on front panels 304 and 306 in the direction of brackets 20 and 60 and backer rails 52.

[0149] FIG. 22 illustrates a top view of a second cover position (b) during the installation of the pole engaging embodiment of cover 300, in which cover 300 is expanded to a maximum edge gap expansion necessary for installation. When cover 300 is pressed in the direction of fence assembly 1, right edge 322 of right connector panel 316 and left edge 324 of left connector panel 318 engage pole 4. Continued application of force in the direction of pole 4 causes the expansion of edge gap 326(b) over the diameter of pole 4.

[0150] Expansion of edge gap 326 is achieved by the collective expansion of obtuse angles 308(b) and 314(b), and by contraction of acute connector angles 320(b). The work is performed by applying a force to cover 300 in the direction of pole 4. Elastic potential energy is accumulated in cover 300 from the expansion of angles 308(b) and 314(b) and contraction of acute connector angles 320(b) as edge gap 326(b) expands sufficiently to equal diameter 14, which is the widest cross-section of pole 4.

[0151] A person of ordinary skill in the art will recognize that there may also be deflection in panels 304, 306, 310, 312, 316, and 318. Panel deflection will also store elastic potential energy. The amount of deflection will be a function of many factors including at least the material choice, thickness of cover 300 material, length 102 of cover 300, length of contact between right edge 322 and left edge 324 as against pole 4, frictional forces between right edge 322 and left edge 324 as against pole 4, and the amount of expansion of edge gap 326 required for installation.

[0152] FIG. 23 illustrates a top view of a third cover position (c) in the installation of cover 300, in which cover 300 is pressed beyond the contact of the second position (b) described above.

[0153] As cover 300 is pressed further in the direction of fence assembly 1, right edge 322 of right connector panel 316 and left edge 324 of left connector panel 318 move past diameter 14 of pole 4. As this happens, edge gap 326(c) is reduced from the maximum length of edge gap 326(b). As edge gap 326(b) reduces to edge gap 326(c) length, energy is released and inward movement of cover 300 may become very rapid.

[0154] In a preferred embodiment, as movement of cover 300 continues further towards position (c), connector radii 328 engage backer rails 52. Movement of cover 300 can continue still further for a distance equal to cover offset 330, which is best seen in FIG. 24. At that point, right front panel 304 contacts bracket 20 at tangent point 332 and left front panel 306 contacts bracket 20 at tangent point 334, which is best seen in FIG. 25. Contact with bracket 20 prevents any further movement of cover 300 in the direction of fence assembly 1.

[0155] At cover 300(c) position, some or all of the energy stored in connector angles 320(c) has been released and connector angles 320(c) have returned to or near to, or have passed, their neutral connector angle 320(a). However, side angles 314(c) and front angle 308(c) are now at their maximum expansion and storing their maximum energy. This is reflected in the maximum outward extension of connector radii 328 (c) against backer rail 52.

[0156] FIG. 24 illustrates a top view of the fourth and final cover 300(d) position in the installation of the pole 4 engaging embodiment, with cover 300 fully installed against fence assembly 1. In this configuration, cover 300 is held securely in place on fence assembly 1.

[0157] When cover 300 is in position cover 300(d), the external force used for installation has been removed. With the force removed, elastic potential energy stored in cover 300 urges front angle 308(c), side angles 314(c), and connector angles 320(c) in the direction of their neutral positions (a). Cover 300 is prevented from fully returning to position 300(a) by engagement of connector edges 322 and 324 with pole 4 and by engagement of connector radii 328 with backer rails 52. Connector angles 320(d) retain elastic potential energy that draws cover 300 against backer rails 52.

[0158] Front angle 308(c) contracts to front angle 308(d). Side angles 314(c) contract to side angle 314(d). Contraction of these angles draws right edge 322 and left edge 324 centrally until they engage pole 4 on the fence assembly 1 side of pole diameter 14. By this contraction edge gap 326(c) is reduced to edge gap 326(d). Edge gap 326(d) defines a latch width for connection on pole 4. In one embodiment, latch width 90 comprises a circular segment on pole 4 that is less than 90 degrees in arc. In this embodiment, latch width 90 discourages right edge 322 and left edge 324 from slipping forward on pole 4.

[0159] Additional potential energy remains may be stored in cover 300 by deflection of connector panels 316 and 318, as well as external panels 338. Additional potential energy may be stored in cover 300 if front angle 308(d) and side angles 314(d) are greater than neutral front angle 308(a) and side angles 314(a).

[0160] FIG. 25 is a comparison of cover 300 positions of expansion and compression of the five panels angles 308, 314 (x2) and 320 (x2), and the movements and engagements of right edge 322, left edge 324, and connector radii 328, before, during, and after installation.

[0161] The distance between right edge 322 and left edge 324 are illustrated as edge gaps 326 in positions (a), (b), (c), and (d). FIG. 25 illustrates the movement of cover 300 as it is installed over pole 4 and against backer rail 52.

[0162] A person of ordinary skill in the art will recognize that there may also be deflection in panels 304, 306, 310, 312, 316, and 318. Panel deflection will also store elastic potential energy. The amount of deflection will be a function of many factors such as the number of panels, material used and material strength, relative width of the panels and the angles between them, length 102 of cover 300, number and length of bracket reliefs 336, and frictional forces between right edge 322 and left edge 324 as against pole 4. These variables may cause differences in the positions described above.

[0163] In the illustrated embodiment above, cover 300 comprises four external panels 338. It will be readily understood by a person of ordinary skill in the art that more or fewer external panels 338 may be elected for use to obtain a different aesthetic effect, but the dynamics of the installation and elastic potential energy retention of cover 300 are the same or equivalent to those disclosed herein
