Description

PANEL FENCE SYSTEM AND METHOD

TECHNICAL FIELD

This invention relates generally to fence systems and more particularly to a panel fence system and method.

BACKGROUND

It is often desirable or even necessary to prevent people from crossing boundaries, such as a perimeter of privately-owned real estate or another key asset,

Free-standing fences may be used to attempt to prevent people from crossing these boundaries. Conventional fences may include, for example, chain link fencing and barbed wire fencing.

SUMMARY

According to embodiments of the present invention, disadvantages and problems associated with previous fence systems may be reduced or eliminated.

In certain embodiments, a fence system includes a support member and a rail attached to the support member such that the rail extends across the support member. The fence system further includes a first panel and a second panel each comprising a primary panel portion having a first edge and a second edge. A first flange is located along at least a portion of the first edge of the primary panel portion, and a second flange is located along at least a portion of the second edge of the primary panel portion. The first and second panels are secured to the rail such that the second edge of the primary panel portion of the first panel is adjacent to the first edge of the primary panel portion of the second panel. The second flange of the first panel is matingly coupled to the first flange of the second panel.

Particular embodiments of the present invention may provide one or more technical advantages. Conventional fences for preventing movement across a particular boundary may include, for example, chain link fencing and barbed wire fencing. Certain individuals attempting to cross the particular boundary may attempt to breach these conventional fences in a number of ways, such as by climbing over the fence, cutting through the fence (e.g., using a saw, axe, or torch), or disassembling one or more exposed fasteners securing portions of the fence. For various reasons, these conventional fences may be ineffective in preventing these attempted breaches. Certain other conventional fences, such as those made of concrete, bricks, and/or stone, may be less susceptible to breach, but these alternative conventional fences may be prohibitively expensive to construct along boundaries of significant length.

The fence system of the present invention may include a number of panels forming a substantially continuous wall that is less susceptible to breach relative to certain conventional fences. In certain embodiments, the fence system of the present invention may reduce or eliminate hand and foot holds. Thus, the fence system of the present invention may be less susceptible to being breached by an individual attempting to climb over the fence system relative to certain conventional fences. In certain embodiments, the fence system of the present invention provides a substantially continuous wall. Thus, the fence system of the present invention may be less susceptible to being breached by an individual attempting to cut through it (e.g., using a saw, axe, or torch), as compared to certain conventional fences. In certain embodiments, the fence system of the present invention is assembled such that all fasteners are located on one side of the fence system (e.g., the "back side" on which the posts and rails are located). Furthermore, the fence system of the present invention may be oriented such that the back side of the fence system is on the secure side of a boundary other side of the fence system (the "attack side") is on the non- secure-side of the boundary. Thus, the fence system of the present invention may be assembled and/or repaired from the secure side of the boundary and may be less susceptible to being breached by an individual attempting to disassemble the fence system from the non-secure side of the boundary. Additionally, the fence system of the present invention may not be prohibitively expensive to construct along boundaries of significant length. Thus, the fence system of the present invention may potentially be a more cost effective solution for certain applications. Furthermore, the fence system of the present invention may be less susceptible to damage than certain conventional fences (e.g., those made of concrete, bricks, metal, and/or stone), such as damage resulting from high winds and/or soil movement.

Certain embodiments of the present invention may include some, all, or none of the above advantages. One or more other technical advantages may be readily apparent to those skilled in the art from the figures, descriptions, and claims included herein.

DESCRIPTION OF EXAMPLE EMBODIMENTS

FIGURES IA- IE illustrate an example panel fence system 100, according to certain embodiments of the present invention. Fence system 100 may include a number of support members 102 (referred to throughout the remainder of this description as posts 102 for simplicity) and a number of rails 104. Each rail 104 may be attached to at least one post 102 such that the rail 104 extends across the at least one post 102 to which it is attached. Fence system 100 may also include a number of panels 106 each secured to one or more rails 104.

In general, fence system 100 may deter and/or substantially prevent movement across a particular boundary. Example boundaries include perimeters of critical assets, perimeters of privately-owned real estate, national borders, or any other suitable boundaries. Certain individuals attempting to cross the particular boundary may attempt to breach fence system 100 in a number of ways, such as by climbing over fence system 100, cutting through fence system 100 (e.g., using a saw, axe, or torch), or attempting to remove panels 106 of fence system 100. Because panels 106 may be secured to rails 104 such that hand and foot holds may be reduced or eliminated, fence system 100 may be less susceptible to being breached by an individual attempting to climb over it relative to certain conventional fences. Additionally, because panels 106 may be secured to rails 104 such that panels 106 form a substantially continuous wall, fence system 100 may be less susceptible to being breached by an individual attempting to cut through it relative to certain conventional fences. Additionally, because panels 106 may be secured to rails 104 such that all fasteners are located on one side (the "back side") of the fence system, fence system 100 may be less susceptible to being breached by an individual attempting to remove panels 106 of fence system 100 relative to certain conventional fences. Thus, in certain embodiments, fence system 100 may be more effective in preventing movement across a particular boundary relative to certain conventional fences.

Posts 102 may be constructed from aluminum, iron, stainless steel, galvanized steel, brass, plastic, or any other suitable material. Furthermore, posts 102 may have any suitable size and shape. For example, posts 102 may be constructed from tubing material of any desired cross section (e.g., rectangular, round, elliptical), solid material of any desired cross section (e.g., rectangular, round, elliptical), channel material, angle iron, I-beam, or any other suitable material. Furthermore, posts 102 may be any suitable length (e.g., four, eight, or twenty feet). As a particular example, posts 102 may be constructed from a twenty-foot length of galvanized steel round tubing. Although fence system 100 is illustrated and primarily described as including a particular number of posts 102, the present invention contemplates fence system 100 including any suitable number of posts 102, according to particular needs.

Posts 102 of fence system 100 may be anchored in the ground (e.g., using concrete 108). In certain embodiments, posts 102 are anchored in the ground such that they are substantially vertical (and, as a result, substantially parallel with one another) regardless of ground slope (as illustrated in FIGURES 2A-2B, described below). Furthermore, the distance between any two adjacent posts 102 (e.g., post 102a and post 102b) may be any suitable distance (e.g., ten feet), and may vary from post 102 to post 102 if appropriate. Rails 104 may be constructed from aluminum, iron, stainless steel, galvanized steel, brass, plastic, or any other suitable material. Furthermore, rails 104 may have any suitable size and shape. For example, rails 104 may be constructed from tubing material of any desired cross section (e.g., rectangular, round, elliptical), solid material of any desired cross section (e.g., rectangular, round, elliptical), channel material, angle iron, I-beam, or any other suitable material. Furthermore, rails 104 may be any suitable length (e.g., four, eight, or twenty feet). As a particular example, rails 104 may be constructed from a twenty foot length of galvanized steel square tubing. Although fence system 100 is illustrated and primarily described as including a particular number of rails 104, the present invention contemplates fence system 100 including any suitable number of rails 104, according to particular needs.

Rails 104 of fence system 100 may each be attached to one or more posts 102. In certain embodiments, a rail 104 may each be attached to a post 102 such that the rail 104 is coupled directly to post 102. For example, the rail 104 may be coupled directly to the post 102 using one or more fasteners, such as screws, bolts, rivets, or any other suitable attachment fasteners. As an additional example, the rail 104 may be coupled directly to post 102 such that the rail 104 is physically connected to the post 102 (e.g., using a weld).

In certain other embodiments, a rail 104 may be attached to a post 102 such that the rail 104 is coupled to the post 102 using a bracket component, such as a rail hanger 110. Rail hanger 110 may include a clamp 112 configured to be attached to a post 102 and a bracket 114 configured to be attached to a rail 104. The bracket 114 may be either physically attached to the clamp 112 (e.g., using a weld) or attached to the clamp 112 using a fastener (e.g., a screw, bolt, rivet, or any other suitable fastener). In certain embodiments, the clamp 112 is attached to a post 102, and a rail 104 is attached to the bracket 114 (either physically attached or attached using a fastener). Thus, rail hanger 1 10 is adapted to attach the rail 104 to the post 102.

Clamps 112 may include any conventional clamp that may be attached to a post 102, such as by tightening a nut 116 of a clamp bolt 118. In certain embodiments, a clamp 112 may have a size and/or shape that corresponds to the size and/or shape of the post 102 to which the clamp 112 is to be attached. For example, a clamp 112 of a rail hanger 110 to be attached to a round post 102 may include a circular metal band having an inner diameter slightly smaller than the outer diameter of the post 102 to which the rail hanger is to be attached such that the claim 112 may be attached to the post 102 by tightening a nut 116 of a clamp bolt 118 (as illustrated in FIGURE 3, described below).

Although particular configurations of rails 104 and rail hangers 110 are illustrated and primarily described, rails 104 and rail hangers 1 10 may be configured in any of a number of ways.

Panels 106 of fence system 100 may be constructed from aluminum, iron, stainless steel, galvanized steel, brass, plastic, or any other suitable material. As a particular example, panels 106 may be constructed from rolled seven-gauge steel. In certain embodiments, each panel 106 includes a primary panel portion 120 having a first edge 126 and a second edge 128. Each panel 106 may further include a first flange 122 located along a first edge 126 of the primary panel portion 120 and a second flange 124 located along a second edge 128 of the primary panel portion 120.

Each of the panels 106 of fence system 100 is adapted to be secured to one or more rails 104 such that the first flange 122 and second flange 124 of each panel 106 matingly couple with flanges of adjacent panels 106. More particularly, the first flange 122 of a particular panel 106 may be configured to matingly couple with a second flange 124 of a first adjacent panel 106, and the second flange 124 of the particular panel 106 may be configured to matingly couple with a first flange 122 a second adjacent panel 106 (as described below). As a result, the primary panel portions 120 of the number of panels 106 of fence system 100, when secured to one or more rails 104, may form a substantially continuous wall. Furthermore, because the primary panel portions 120 of panels 106 may form a substantially continuous wall, panels 106 may further include a plurality of apertures 132 that may facilitate visibility through the substantially continuous wall.

Although primary panel portions 106 of panels 106 are described as forming a substantially continuous wall, in certain applications there may be gaps between adjacent edges of primary panel portions 120 of adjacent panels 106. As described in further detail below with respect to FIGURES 2A-2B, an advantage of certain embodiments of the present invention is that the gaps between adjacent edges of primary panel portions 120 of adjacent panels 106 may not pass through fence system 100 as adjacent flanges of the adjacent panels 106 may be matingly coupled such that adjacent flanges close the gap between the adjacent edges. Panels 106 may be secured to one or more rails 104 using one or more fasteners, such as a screws, bolts, rivets, staples, or any other suitable fasteners. As a particular example, a panel 106 may be secured to one or more rails 104 using a bolt (e.g., bolt 130a illustrated in FIGURE 1C). In certain other embodiments, a panel 106 is secured to a rail 104 by physically joining the panel 106 to the rail 104 (e.g. by welding the panel 106 to the rail 104 or "clinching" the panel 106 to the rail 104). As a particular example, a panel 106 may be clinched the panel 106 to a rail 104 using and a TOG-L-LOC^® sheet metal joining system manufactured by BTM CORPORATION (e.g., clinch point 130b, illustrated in FIGURE 1C). As a particular example, panel 106g may be secured to one or more rails 104

(e.g., using a fastener or physically joined) such that panel 106g is adjacent to panel 106f and panel 106h (as illustrated in FIGURED IA- 1C). Furthermore, panel 106g may be oriented with respect to panel 106f such that first edge 126g is adjacent to second edge 128f and first flange 122g is matingly coupled to second flange 124f. Additionally, panel 106g may be oriented with respect to panel 106h such that second edge 128g is adjacent to first edge 126h and second flange 124g is matingly coupled to first flange 122h. Thus, the primary panel portions 12Oe- 12Og of panels 106e-106g may form a substantially continuous wall.

In certain embodiments (as illustrated in FIGURES ID- IE), the first flange 122 of each panel 106 includes a protrusion 122' extending from the first edge 126 of the primary portion 120 of the panel 106, and a tab 122" extending from the protrusion 122'. As a particular example, the protrusion 122' of a first flange 122 of a panel 106 may extend in a direction substantially perpendicular to the primary panel portion 120 of the panel 106, and the second portion 122" of the first flange 122 may extend in a direction substantially parallel to the primary panel portion 120 of the panel 106. Additionally, in certain embodiments (illustrated in FIGURES ID- IE), the second flange 124 of each panel 106 includes a protrusion 124' extending from the second edge 128 of the primary portion 120 of the panel 106 and a tab 124" extending from the protrusion 124'. As a particular example, the protrusion 124' of the second flange 124 of a panel 106 may extend in a direction substantially perpendicular to the primary panel portion 120 of the panel 106 and the tab 124" of the second flange 124 of the panel 106 may extend in a direction substantially parallel to the primary panel portion 120 of the panel 106 (and in the same direction relative to the primary panel portion 120 of the panel 106 as the second portion 122" of the first flange 122 of the panel 106).

Furthermore, the first flange 122 of a particular panel 106 may be configured to matingly couple with a second flange 124 of a first adjacent panel 106 such that the tab 122" of the first flange 122 of the particular panel 106 is substantially parallel with the tab 124" of the second flange 124 of the first adjacent panel 106. The tabs 122" and 124" may also be substantially parallel to a rail 104 such that the particular panel 106 and the first adjacent panel 106 may be secured to the rail 104 at a single point using a single fastener. For example, the rail 104 may be attached to tabs 122" and 124" using a single bolt 130a passing through rail 104, tab 122", an tab 124". As an additional example, in embodiments in which rail 104 is constructed of a channel, a TOG-L-LOC^® sheet metal joining system (described above) may be inserted into the opening defined by the channel such that rail 104 may be attached to tabs 122" and 124" using a clinch point 130b. Similarly, the second flange 124 of the particular panel 106 may be configured to matingly couple with a first flange 122 of a second adjacent panel 106 such that the tab 124" of the second flange 124 of the particular panel 106 is substantially parallel with the tab 122" of the first flange 122 of the adjacent panel 106. The tabs 124" and 122" may also be substantially parallel to the rail 104 such that the particular panel 106 and the second adjacent panel 106 may be secured to the rail 104 at a single point using a single fastener. For example, the rail 104 may be attached to tabs 124" and 122" using a single bolt 130a passing through rail 104, tab 124", an tab 122". As an additional example, in embodiments in which rail 104 is constructed of a channel, a TOG-L-LOC^® sheet metal joining system (described above) may be inserted into the opening defined by the channel such that rail 104 may be attached to tabs 124" and 122" using a single clinch point 130b.

Although adjacent panels 106 are capable of being secured to a rail 104 at a single point (as described above), the present invention contemplates adjacent panels being secured to the rail 104 at any suitable number of points, according to particular needs.

As a particular example, in the above-described example in which panel 106g is secured to a rail 104 such that panel 106g is adjacent to panel 106f and panel 106h, panels 106f-106h may each include a first flange 122 having a protrusion 122' and tab 122" and a second flange 124 having a protrusion 124' and a tab 124" (as described above).

Furthermore, first flange 122g of panel 106g may be matingly coupled with second flange 124f of panel 106f such that: • protrusion 122g' of first flange 122g is adjacent to protrusion 124f of second flange 124f ; and • tab 122g" of first flange 122g is adjacent to and substantially parallel with tab 124f ' of second flange 124f.

In certain embodiments (e.g., embodiments in which panel 106f and panel 106g are oriented at substantially the same angle, as illustrated in FIGURES IA- 1C), protrusion 122g' of first flange 122g may be substantially parallel with protrusion

124f of second flange 124f. In certain other embodiments (e.g., embodiments in panel 106f and panel 106g are oriented at different angles, as illustrated in FIGURES

2A-2C) protrusion 122g' of first flange 122g may not be substantially parallel with protrusion 124f of second flange 124f

Additionally, tab 122g" of first flange 122g and tab 124f ' of second flange 124f, in addition to being substantially parallel with one another, may also be substantially parallel with the rail 104 to which panels 106f and 106g are attached (or tangent to the rail 104 in embodiments in which the rail 104 is round) such that tabs 122g" and 124f ' ( and, as a result, panels 106f and 106g) may be attached to one another as well as the rail 104 at a single point using a single fastener. For example, tabs 122g" and 124f ' may be attached to rail 104 using a single bolt 130a passing through rail 104, tab 122g", and 122f '. Alternatively, in embodiments in which rail 104 is constructed of a channel, a TOG-L-LOC^® sheet metal joining system (described above) may be inserted into the opening defined by the channel such that rail 104 may be attached to tabs 122g" and 124f ' using a single clinch point 130b.

Similarly, second flange 124g of panel 106g may be matingly coupled with first flange 122h of panel 106h such that:

• protrusion 124g' of second flange 124g is adjacent to protrusion 122h' of first flange 122h; and

• tab 124g" of second flange 124g is adjacent to and substantially parallel with tab 122h" of first flange 122h.

In certain embodiments (e.g., embodiments in panel 106g and panel 106h are oriented at the same angle, as illustrated in FIGURES 1A-1C), protrusion 124g' of second flange 124g may be substantially parallel with protrusion 122h' of first flange 122f. In certain other embodiments (e.g., embodiments in panel 106g and panel 106h are oriented at different angles, as illustrated in FIGURES 2A-2C) protrusion 124g' of second flange 124g may not be substantially parallel with protrusion 122h' of first flange 122h.

Additionally, tab 124g" of second flange 124g and tab 122h" of first flange 122h, in addition to being substantially parallel with one another, may be substantially parallel with the rail 104 to which panels 106g and 106h are attached (or tangent to the rail 104 in embodiments in which the rail is round) such that panels 106g and 106h may be attached to the rail 104 at a single point. For example, tabs 122g" and 124f ' may be attached to rail 104 using a single bolt 130a passing through rail 104, tab 122g", and 122f". Alternatively, in embodiments in which rail 104 is constructed of a channel, a TOG-L-LOC^® sheet metal joining system (described above) may be inserted into the opening defined by the channel such that rail 104 may be attached to tabs 122g" and 124f ' using a clinch point 130b.

Securing adjacent panels 106 to a rail 104 using tabs of matingly coupled flanges of the adjacent panels 106 (as described above) may allow fence system 100 to be constructed and/or repaired from a single side (i.e., the side on which posts 102 and rails 104 are located), which may be important in applications in which fence system 100 is constructed along a secure boundary. Additionally, in embodiments in which a fastener (e.g., bolt 130a) is used to secure the tabs of the flanges of adjacent panels 106 to a rail 104, securing adjacent panels 106 to a rail 104 using tabs of the matingly coupled flanges of the adjacent panels 106 (as described above) may prevent the fastener from passing through the primary panel portion 120 of either panel (as illustrated in FIGURE 1C), which may reduce the susceptibility of fence system 100 to being breached by an individual attempting remove panels 106 from fence system 100 as well as by an individual attempting to climb over fence system 100 (as a fastener passing through the primary panel portion 120 of a panel may provide a hand or foot hold).

Although panels 106 are illustrated and primarily described above as including primary panel portions 120, first flanges 122, and second flanges 124 each having particular configurations, the present invention contemplates panels 106 comprising primary panel portions 120, first flanges 122, and second flanges 124 having any suitable configurations such that a flange of a first panel 106 is adapted to matingly couple with a flange of an adjacent panel 106 when the panels 106 are secured to one or more rails 104. For example, panels 106 including primary panel portions 120, first flanges 122, and second flanges 124 having example alternative configurations are illustrated in FIGURES 4A-4D, described in further detail below.

Because fence system 100 may include a number of panels 106 forming a substantially continuous wall, fence system 100 may be less susceptible to breach relative to certain conventional fences. In certain embodiments, fence system 100 may reduce or eliminate hand and foot holds. Thus, the fence system 100 may be less susceptible to being breached by an individual attempting to climb over fence system 100 relative to certain conventional fences. In certain embodiments, the fence system 100 provides a substantially continuous wall. Thus, the fence system 100 may be less susceptible to being breached by an individual attempting to cut through it (e.g., using a saw, axe, or torch), as compared to certain conventional fences. In certain embodiments, fence system 100 is assembled such that all fasteners are located on one side of the fence system (e.g., the "back side" on which the posts and rails are located). Furthermore, fence system 100 may be oriented such that the back side of the fence system is on the secure side of a boundary other side of the fence system (the "attack side") is on the non-secure-side of the boundary. Thus, fence system 100 may be assembled and/or repaired from the secure side of the boundary and may be less susceptible to being breached by an individual attempting to disassemble fence system 100 from the non-secure side of the boundary.

Additionally, fence system 100 may not be prohibitively expensive to construct along boundaries of significant length. Thus, fence system 100 may potentially be a more cost effective solution for certain applications. Furthermore, fence system 100 may be less susceptible to damage than certain conventional fences (e.g., those made of concrete, bricks, metal, and/or stone), such as damage resulting from high winds and/or soil movement.

Although a particular implementation of fence system 100 is illustrated and primarily described, the present invention contemplates any suitable implementation of fence system 100 according to particular needs. Although a particular number components of fence system 100 have been illustrated and primarily described above, the present invention contemplates fence system 100 including any suitable number of such components. FIGURES 2A-2B illustrates an example configuration of a panel fence system

100 constructed along a boundary having varying slope, according to certain embodiments of the present invention. In the illustrated configuration, a number of posts 102 are anchored in the ground (e.g., using concrete 108) such that they are substantially vertical (and, as a result, substantially parallel with one another) regardless of ground slope. Additionally, a number of rails 104 are coupled to the one or more of the posts 102 (e.g., using rail hangers 110, as described above). Each rail 104 may extends across the one or more posts 102 to which it is attached and may be oriented generally parallel to the ground at the location along the boundary at which it is installed. A number of panels 106 may each be secured to the rails 104. Furthermore, each panel 106 may be oriented substantially perpendicular to the ground at the point along the boundary at which it is located. As a result, adjacent panels 106 may be oriented at different angles such that a gap exists between adjacent edges of the primary panel portions 120 of the adjacent panels 106 (e.g., gap 134 between primary portions 120a and 120b of adjacent panels 106a and 106b, described below). Furthermore, the gap between adjacent edges of primary panel portions 120 of adjacent panels 106 may vary in width, the variance in width corresponding to the difference in the angles at which the adjacent panels 106 are oriented. The gap between the adjacent edges of the first portions 120 of the adjacent panels 106, however, may not pass through fence system 100, as adjacent flanges of the adjacent panels 106 may be matingly coupled such that adjacent flanges close the gap between the adjacent edges. In other words, adjacent flanges of adjacent panels 106 may permit a certain degree of "fanning" between the panels such that fence system 100 may be installed along a boundary having varying ground slope.

As a particular example, adjacent panels 106a and 106b may each be secured to rails 104 such that second flange 124a of panel 106a is matingly coupled to first flange 122b of panel 106b. More particularly, second flange 124a of panel 106a may be matingly coupled with first flange 122a of panel 106a such that protrusion 124a' of second flange 124a is adjacent to protrusion 122b' of first flange 122b and tab 124g" of second flange 124g is adjacent to and substantially parallel with tab 122h" of first flange 122h, as described above. Because the severity of the ground slope is greater at the point at which panel 106b is located than at the point at which panel 106a is located, panel 106a may be oriented at an angle relative to horizontal that is smaller than the angle relative to horizontal at which panel 106b is oriented. As a result, there may be a gap 134 between second edge 128a of panel 106a and first edge 126b of panel 106b, gap 134 being widest at the point nearest the ground.

Tab 124a" of second flange 124a of panel 106a, however, may be sufficiently wide as to close gap 134. In other words, tab 124a" may be at least slightly wider that the widest portion of gap 134 (i.e., the point nearest the ground) such that at least a portion of tab 124a" overlaps at least a portion of tab 122b" of first flange 122b of panel 106b at all points along the adjacent edges 128a and 126b of panels 106a and 106b. Thus, assuming that fence system 100 is to be installed such that there are no gaps (i.e., all gaps between adjacent edges of primary portions 120 of adjacent panels 106 are filled, as described above), the width of tabs 124" of second flanges 124 of panels 106 may define the maximum variation in orientation angle between adjacent panels 106 (i.e., the degree of fanning that is permitted between adjacent panels 106). Furthermore, the maximum variation in orientation angle between adjacent panels 106 may define the maximum variation in ground slope over which fence system 100 may be installed. Stated differently, by increasing the width of tabs 124" of second flanges 124 of panels 106, fence system 100 may be adapted to traverse terrain with greater variations in ground slope.

Additionally, because panels 106 are oriented substantially perpendicular with the ground (as opposed to, for example, substantially parallel with posts 108), the top of fence system 100 may be a generally continuous smooth curve as fence system 100 traverses a boundary of varying ground slope.

FIGURE 3 illustrates an example rail hanger 110 of the panel fence system 100 illustrated in FIGURE 1 , according to certain embodiments of the present invention. Rail hanger 1 10 may include a clamp 1 12 configured to be attached to a post 102 and a bracket 1 14 configured to be attached to a rail 104. The bracket 1 14 may be either physically attached to the clamp 112 (e.g., using a weld) or attached to the clamp 112 using a fastener (e.g., a screw, bolt, rivet, or any other suitable fastener). In certain embodiments, the clamp 1 12 is attached to a post 102, and a rail 104 is attached to the bracket 114 (either physically attached or attached using a fastener). Thus, rail hanger 110 is adapted to attach the rail 104 to the post 102.

Clamps 112 may include any conventional clamp that may be attached to a post 102, such as by tightening a nut 116 of a clamp bolt 118. In certain embodiments, a clamp 112 may have a size and/or shape that corresponds to the size and/or shape of the post 102 to which the clamp 112 is to be attached. For example, a clamp 112 of a rail hanger 1 10 to be attached to a round post 102 may include a circular metal band having an inner diameter slightly smaller than the outer diameter of the post 102 to which the rail hanger is to be attached such that the claim 112 may be attached to the post 102 by tightening a nut 116 of a clamp bolt 118.

FIGURE 5 illustrates an example method 500 for constructing a panel fence system 100, according to certain embodiments of the present invention. The method begins at step 502.
