Description

Technical Field

[0001] The present invention relates to a fence panel, and more particularly to a fence panel comprising a front panel and a plurality of reinforcing panels. The fence panel according to the present invention can be used for security purposes to prevent intruders from damaging certain areas, and in particular to increase the time required for intruders to damage the fence panel. Background Art

[0002] GB2584460 discloses a safety fence panel comprising vertical safety mesh sheets which are spaced apart during use and connected by an intermediate sheet which is inclined relative to the horizontal. The intermediate sheet may be non-fixedly connected to the safety mesh sheet by a screw connector to allow relative movement between the intermediate sheet and the safety mesh sheet, thereby allowing the panel to be folded up for storage. The intermediate sheet may be inclined at an angle to the safety mesh sheet.

[0003] EP3775440 discloses a fence mesh assembly, which includes a front mesh plate, a rear mesh plate and a plurality of cross mesh plates, wherein the cross mesh plates are arranged between and connected to the front mesh plate and the rear mesh plate, and the cross mesh plates are distributed on the front mesh plate and the rear mesh plate.

[0004] These arrangements in the art typically include a front mesh panel and a rear mesh panel extending parallel to the front mesh panel, which increases the overall weight and cost of the fence and allows debris to accumulate between the front and rear mesh panels. There remains a need for a fence panel that is more cost effective and lighter weight without affecting the time required for an attacker to breach the fence panel (delay time).

[0005] US10364589 discloses a barrier comprising a first mesh panel having spaced-apart horizontally extending reinforcement structures and at least one second mesh panel positioned between the two reinforcement structures. Summary of the invention

[0006] The object of the present invention is to provide a fence panel that is strong and effective against intruders, thereby increasing the delay time (i.e., the time required for an intruder to breach the fence panel). In particular, the fence panel should be able to withstand an attack by an intruder for several minutes, for example, at least five minutes as specified in the ASTM F2781 specification for the aggression test.

[0007] Another object of the present invention is to provide a fence suitable for use as a safety fence having enhanced anti-climbing and anti-wear properties.

[0008] According to a first aspect of the present invention, there is provided a fence panel comprising a front panel and a plurality of reinforcing panels, wherein the plurality of reinforcing panels comprise one or more first reinforcing panels connected to a first side portion of the front panel and extending away from the first side portion and one or more second reinforcing panels extending away from the first side portion of the front panel, wherein each of the one or more second reinforcing panels is connected to at least two of the first reinforcing panels.

[0009] Surprisingly, when the fence panel includes multiple reinforcement panels according to the present invention, an attacker needs longer time to damage and / or penetrate the fence panel, thereby providing an increased delay time for the intruder to cut through the fence. Non-limiting examples of cutting tools for this purpose are manual and / or electric cutting tools, such as grinders.

[0010] Therefore, the fence panel according to the present invention is light and low cost, while providing a longer delay time for any intruder attempting to damage the fence. In addition, since the reinforcement plate is only located on one side of the front panel, the front panel does not provide climbing assistance to intruders.

[0011] The second reinforcing plate is used to hold the first reinforcing plate in place so that the first reinforcing plate is not easily bent or moved by an attacker. In addition, since the second reinforcing plate is connected to the first reinforcing plate and extends away from the first side of the front plate, the second reinforcing plate needs to be positioned at a certain angle to the first reinforcing plate. The first reinforcing plate and the second reinforcing plate are both located behind the front plate and extend at different angles along the surface of the front plate, which provides an additional obstacle for potential attackers, thereby reducing the area of ​​the front plate that is not intersected by the reinforcing plates.

[0012] In order to damage the fence panel of the present invention, an intruder must cut away a portion of the front panel and then cut the reinforcement panel. Due to the arrangement of the reinforcement panel, only a small portion of the front panel can be removed. Once a portion has been removed, the arrangement of the reinforcement panel means that it is difficult to subsequently cut the reinforcement panel using a cutting tool.

[0013] The term "fence panel" is to be interpreted in accordance with the ordinary usage of that word, i.e. to refer to a panel that can be used in combination with fence posts to form a fence. Thus, a fence panel is not self-supporting but is used to create a fence or other barrier that has some form of support.

[0014] The front panel, the one or more first reinforcing panels and / or the one or more second reinforcing panels may be mesh panels.Therefore, the front panel, the one or more first reinforcing panels and / or the one or more second reinforcing panels may include a plurality of intersecting wires connected together to form a mesh.

[0015] The mesh of the one or more first reinforcing panels and / or the one or more second reinforcing panels may be identical to the mesh of the front panel. This increases ease of construction and provides a simpler, more cost-effective arrangement.

[0016] The term "mesh" should be interpreted as a sheet comprising intersecting solid wires that are interconnected to form an aperture. The mesh may include a plurality of wires extending in a first direction and a plurality of wires extending in a second direction, such that at least some of the wires in the first direction intersect at least some of the wires in the second direction, or each of the wires in the first direction intersects each of the wires in the second direction. The first direction may be a vertical direction. The second direction may be a horizontal direction, or the second direction may be perpendicular to the first direction.

[0017] The one or more second reinforcing plates may be in contact with and / or connected to the first side of the front plate. Such connection may include welding, windings, rings, clamps or other suitable connecting means. Such connection between the front plate and the second reinforcing plates may further increase the delay time.

[0018] One or more first reinforcing plates and / or one or more second reinforcing plates may be perpendicular to the front plate. It has been found that this arrangement can form a strong and stable fence panel that can withstand attacks and increase delay time, and is easy to assemble. This is particularly true in the case of an intruder using manual and / or powered cutting tools, where this arrangement makes it difficult for an intruder to reach the reinforcing plates with the cutting tools, even after the front plate has been damaged.

[0019] The one or more first reinforcing plates may be planar and may be rectangular. The front plate may have a plurality of, preferably more than two, first reinforcing plates connected to the front plate. The plurality of first reinforcing plates may be parallel to each other. All first reinforcing plates may be parallel to each other. The one or more first reinforcing plates may be vertical plates or horizontal plates. This arrangement is easy to construct from component parts.

[0020] The one or more second reinforcing plates may be planar.The plurality of first reinforcing plates may include all plates extending parallel to each other in the first direction, and the plurality of second reinforcing plates may include all plates extending parallel to each other in the second direction.

[0021] The one or more second reinforcing plates may be perpendicular to the one or more first reinforcing plates. In an embodiment where the one or more first reinforcing plates are vertical plates, the one or more second reinforcing plates are horizontal plates. The one or more first reinforcing plates may be connected to the face of the one or more second reinforcing plates along their edges.

[0022] The one or more second reinforcing plates may extend along the top and / or bottom of the first reinforcing plate. Thus, the top and / or bottom edge of the first reinforcing plate may be connected to the one or more second reinforcing plates. The one or more second reinforcing plates may extend along substantially the entire length of the front plate (i.e. more than 85% of the length of the front plate). There may be only one second reinforcing plate connected to more than two first reinforcing plates, preferably to all of the first reinforcing plates. The second reinforcing plate may extend along the top of the first reinforcing plate.

[0023] Preferably there is only one front panel in the fence panels.

[0024] The length of the first reinforcing plate in one direction may be shorter than the length of the front plate in the corresponding direction. For example, the height of the first reinforcing plate may be shorter than the height of the front plate. Therefore, the first reinforcing plate may not reach the top of the front plate. Preferably, the first reinforcing plate is positioned at the same horizontal height of the front plate.

[0025] Alternatively, the one or more second reinforcing plates may be connected to the first reinforcing plate at an angle of between 20 and 70 degrees to the first reinforcing plate. This range of angles means that the area of ​​the front plate that is not protected by the reinforcing plate is small, thereby reducing the space that an attacker can easily cut. An angle greater than 20 degrees ensures that the connection between the first reinforcing plate and the front plate does not interfere with the connection between the second reinforcing plate and the first reinforcing plate. An angle less than 70 degrees ensures that the second reinforcing plate effectively traverses a larger portion of the front plate.

[0026] The one or more second reinforcing plates can be connected to the face of one or more first reinforcing plates at a necessary angle along its edge. It should be understood that in order to connect at least two first reinforcing plates, the second reinforcing plate extends between the at least two first reinforcing plates and is connected to each of the at least two first reinforcing plates.

[0027] The one or more second reinforcing plates may include a bend. The one or more second reinforcing plates may include two or more bends, preferably three or more bends. The one or more second reinforcing plates include at least one bend, making the fence plate highly resistant to cutting tools, as a single plate protects a wider area of ​​the front plate. Therefore, this arrangement increases the delay time for any potential intruder to pass through the fence plate, as this arrangement increases the difficulty for an intruder to use a cutting device to reach the one or more first reinforcing plates and / or second reinforcing plates after the front plate has been damaged.

[0028] In a preferred embodiment, the angle between the first reinforcing plate and the second reinforcing plate is preferably in the range of 30 to 60 degrees, more preferably in the range of 40 to 50 degrees. Preferably, the angle between each first reinforcing plate and the second reinforcing plate is between 20 and 70 degrees, preferably between 30 to 60 degrees, more preferably between 40 to 50 degrees.

[0029] Surprisingly, when the angle between the first reinforcing plate and the second reinforcing plate is in the range of 30 to 60 degrees, more preferably in the range of 40 to 50 degrees, it takes longer for an attacker to damage the fence panel, as this will minimize the cutting space available to the attacker, thereby increasing the difficulty of damaging the fence panel. It has also been found that angles outside the above range will hinder the connection means, such as spiral windings, that connect the reinforcing plate to the front panel.

[0030] At least a portion of the second reinforcing plate may extend parallel to at least a portion of the first reinforcing plate. The portions of the first and second reinforcing plates may abut against each other, thereby forming a double-layer reinforcing plate. Portions of the first reinforcing plate may extend parallel to and abut against the second reinforcing plate. Portions of the first reinforcing plate may extend parallel to and abut against portions of the same second reinforcing plate.

[0031] Thus, the second reinforcing plate may contact the first reinforcing plate at multiple points along the length of the first and second reinforcing plates.The portions of the first reinforcing plate in contact with the second reinforcing plate may be evenly distributed along the length of the first reinforcing plate.

[0032] The present inventors have found that having at least a portion of the first and second reinforcing plates extend in parallel and abut each other (ie a double layer portion) increases the strength of the fence panel and increases the difficulty of damaging the panel with a cutting device.

[0033] Therefore, one or more bends in the second reinforcing plate may be at an angle formed by the connection of the first reinforcing plate and the second reinforcing plate, i.e., may be between 20 and 70 degrees, preferably between 30 and 60 degrees. This means that a portion of the second reinforcing plate may extend parallel to the first reinforcing plate and abut against the first reinforcing plate, and then the bends form the necessary angle between the first and second reinforcing plates.

[0034] Furthermore, the size of the spacing results in an aperture that is too small for an attacker to gain an easy foothold, even if a portion of the front plate is removed, thereby providing additional anti-climbing properties.

[0035] A first reinforcing plate may be connected to a second reinforcing plate at a first side of the first reinforcing plate and may be adjacent to another first reinforcing plate at a second side of the first reinforcing plate without a second reinforcing plate at the second side. A second reinforcing plate may extend between and be connected to two first reinforcing plates. This may form a unit of three reinforcing plates, with the second reinforcing plate being located between two first reinforcing plates, which may be repeated along the length of the front panel.

[0036] Thus, a first reinforcing plate may be adjacent to another first reinforcing plate without a second reinforcing plate therebetween, and / or a first reinforcing plate may be adjacent to another first reinforcing plate connected to a second reinforcing plate extending therebetween. This may be true for each first reinforcing plate in a fence panel, except for first reinforcing plates at the ends of the fence panels.

[0037] The first reinforcing plate may have: a first spacing between two adjacent first reinforcing plates, with no second reinforcing plate between the two adjacent first reinforcing plates having the first spacing; and a second spacing between two adjacent reinforcing plates, with a second reinforcing plate between the two adjacent reinforcing plates having the second spacing, wherein the first spacing is smaller than the second spacing.

[0038] It has been found that this spacing makes the fence very difficult for an intruder to cut and subsequently break through, thereby increasing the delay time for any would-be intruder.

[0039] In embodiments where the second reinforcing plate meets the first reinforcing plate at an angle of 20 to 70 degrees, the minimum distance between the portions of the second reinforcing plate extending between the first reinforcing plates may be between 200 mm and 300 mm, preferably between 220 mm and 280 mm. The angle at which these portions of the second reinforcing plate meet the first reinforcing plate means that an attacker cannot easily reach the portion of the first side of the front plate where there is an acute angle directly below the second plate and beside the first reinforcing plate.

[0040] Therefore, the rectangular portion of the front panel formed between adjacent first reinforcing panels connected by the second reinforcing panels, which does not intersect with the second reinforcing panels, is preferably between 200 mm and 300 mm in a dimension parallel to the first reinforcing panels, more preferably between 220 mm and 280 mm. The rectangular portion is preferably between 70 mm and 200 mm in a dimension perpendicular to the first reinforcing panels, preferably between 120 mm and 180 mm.

[0041] The distance between adjacent parallel first reinforcing plates may be 70 mm to 200 mm, and preferably may be between 120 mm and 180 mm.

[0042] The front panel and / or the plurality of reinforcing panels may comprise vertical wires and horizontal wires. It will be appreciated that the vertical is defined relative to the surface on which the fence panels are located, the surface on which the fence panels are located defining the horizontal surface.

[0043] The first group of wires in the mesh fence panel and / or the plurality of reinforcing plates may be vertical wires. The second group of wires in the mesh fence panel and / or the plurality of reinforcing plates may be horizontal wires. The first group of wires may consist of all wires extending in parallel in a first direction, and the second group of wires may consist of all wires extending in parallel in a second direction.

[0044] More than 90% of the wires in the first set of wires of the mesh front panel may be connected to the first reinforcing plate or crossed by the second reinforcing plate. Preferably, each wire in the first set of wires of the mesh front panel may be connected to the first reinforcing plate or crossed by the second reinforcing plate.

[0045] In some embodiments, 50% or more of the wires in the first set of wires of the mesh front panel can be connected to the first reinforcing plate, especially when the second reinforcing plate is perpendicular to the first reinforcing plate. Therefore, each other parallel wire in the front panel (e.g., each other vertical wire) can be connected to the first reinforcing plate. In some embodiments, more than 90% of the wires in the first set of wires of the mesh front panel can be crossed by the second reinforcing plate. Surprisingly, these arrangements increase the difficulty of breaking through the fence plate, thereby increasing the delay time.

[0046] One or more of the one or more second reinforcing plates may only cross one wire that is not connected to the first reinforcing plate, especially in embodiments where the second reinforcing plate is connected to the first reinforcing plate at an angle between 20 and 70 degrees. This minimizes the potential available space for cutting tools, making it difficult for an attacker to easily penetrate the fence.

[0047] Preferably, the front plate and / or the plurality of reinforcing plates are formed from a wire having a core diameter of less than 4 mm, preferably less than 3.5 mm, and more preferably about 3 mm.

[0048] It has been found that wire of this diameter will vibrate when attacked by abrasive tools and has sufficient strength to resist attack by tools such as bolt cutters, thereby increasing the time required for an intruder to breach the fence.

[0049] The spacing between the wires of the plurality of reinforcing plates may be different from the spacing between the wires of the front plate. The spacing between the wires of the plurality of reinforcing plates may be the same as the spacing between the wires of the front plate.

[0050] The spacing between the second set of wires in the reinforcing plate may be greater than the spacing between the second set of wires in the front plate. Thus, the spacing between the horizontal wires of the reinforcing plate may be greater than the spacing between the horizontal wires of the front plate. The spacing between the first set of wires in the reinforcing plate may be the same as the spacing between the second set of wires in the front plate. The spacing between the second set of wires in the reinforcing plate may be the same as the spacing between the first set of wires in the front plate.

[0051] Preferably, the spacing between the second set of wires in the front plate and / or the spacing between the first set of wires in the reinforcing plate is 30 mm or less, preferably 20 mm or less, more preferably 13 mm or less. Preferably, the spacing between the second set of wires in the front plate and / or the spacing between the first set of wires in the reinforcing plate is 5 mm or more, preferably 10 mm or more. Therefore, the spacing between the horizontal wires in the front plate and / or the spacing between the vertical wires in the reinforcing plate can be between 5 mm and 30 mm, preferably between 10 mm and 20 mm.

[0052] Preferably, the spacing between the first set of wires in the front plate and / or the spacing between the second set of wires in the reinforcing plate is 100 mm or less, preferably 90 mm or less, most preferably 80 mm or less. Preferably, the spacing between the first set of wires in the front plate and / or the spacing between the second set of wires in the reinforcing plate is 60 mm or more, preferably 70 mm or more. Therefore, the spacing between the vertical wires in the front plate and / or the spacing between the horizontal wires in the reinforcing plate can be between 60 mm and 100 mm, preferably between 70 mm and 90 mm.

[0053] The front plate may have a first spacing between adjacent horizontal wires and a second spacing between adjacent vertical wires, the second spacing being greater than the first spacing.

[0054] The reinforcing plate may have a first spacing between adjacent horizontal wires and may have a second spacing between adjacent vertical wires, the second spacing being smaller than the first spacing.

[0055] The wire can be made of steel, preferably with 50% welding strength and at least 400N / mm 2 Made of high tensile strength steel for tensile strength.

[0056] The width (ie the dimension extending away from the fence panel) of the one or more first reinforcing panels and the one or more second reinforcing panels may be the same. The width of the one or more first reinforcing panels and the one or more second reinforcing panels may be different.

[0057] One or more first reinforcing plates, and optionally further one or more second reinforcing plates, may be loosely connected to the front plate. One or more first reinforcing plates, and optionally further one or more second reinforcing plates, may be loosely connected to the front plate using a connecting means. The connecting means may be, for example, a spiral winding.

[0058] It has been found that when one or more of the first and / or second reinforcing plates are loosely connected to the front plate, for example with a spiral winding, it takes an attacker longer to break through the fence. Due to the vibration caused by the attacker trying to break through the security fence plate, the spiral winding may move out of position, which may cause the fence plate to shake on the cutting edge of the grinding disc. This increases the delay time and may even cause the grinding disc to break.

[0059] The winding also provides additional material that the attacker must cut to breach the fence, further increasing the delay time.

[0060] The one or more second reinforcing plates may be connected to the one or more first reinforcing plates by welding, windings, rings, clips or other suitable connection means. Preferably, the connection means is a loose connection means, i.e. the connection means allows a certain degree of movement. Such connection may be located at or towards the side of the reinforcing plate away from the front plate. This makes it more difficult for an intruder to penetrate the one or more first reinforcing plates and / or the second reinforcing plates, as the connection means may move due to vibrations caused by an attacker trying to break through the security fence plate, thereby causing the fence plate to vibrate.

[0061] One or more second reinforcing panels may also be connected to one or more first reinforcing panels using connecting means such as wraps, which connect the first reinforcing panels to the front panel. This provides a cost-effective and simple method of holding the reinforcing panels together.

[0062] The fence panels may also include a ceramic rod at the end of one or more of the first and / or second reinforcing plates opposite the closest front plate. Preferably, the ceramic rod is located away from the front plate along the end of the first reinforcing plate. The ceramic rod may be found at the end of each first and / or second reinforcing plate opposite the closest front plate. This may further increase the delay time as any attacker would need to cut through the ceramic rod and the plate.

[0063] The fence panel may be free of a rear panel (i.e. a panel parallel to and not spaced away from the front panel). This has been found to help reduce the overall weight of the fence panel compared to conventional fences comprising reinforcement panels in the art (conventional fences typically comprise a front fence panel and a rear fence panel). Thus, the fence panel according to the invention provides a lighter, cost-effective method without compromising delay time.

[0064] Furthermore, in some arrangements in the art it has been found that the presence of the rear panel allows debris to accumulate on the bottom of the rear panel and in the space between the front and rear panels which is undesirable and is not seen in the fence panels of the present invention.

[0065] The bottom portion of the fence panel may be embedded in concrete. Thus, the bottom portion of the front panel and the bottom portion of the first reinforcing panels may be embedded in concrete. The concrete may extend below the ground level in which the fence is located. The fence posts may also be embedded in concrete. This increases the strength of the fence as it means that the fence cannot be destroyed by simply cutting the front panel. Furthermore, each first reinforcing panel then holds up the front panel in the same way as the fence posts.

[0066] The fence panel may be without a bottom panel (ie the panel extending along the bottom of the first reinforcing panel away from the front panel).

[0067] The fence panels preferably meet the tests outlined in ASTM F2781-15. The fence panels may meet the moderate threat test (battery-operated angle disc grinders, entry delay greater than 10 minutes) and / or the aggressive threat test (various tools such as pneumatic saws and electric disc grinders, entry delay greater than 5 minutes).

[0068] Thus, the fence panel according to the present invention provides a sufficiently strong fence panel with reduced material costs compared to fence panels comprising a front panel, a reinforcing panel and a rear panel. This helps to reduce the overall weight of the fence panel and minimize unnecessary accumulation of debris.

[0069] According to a second aspect of the present invention, a method for manufacturing the above-mentioned fence panel is provided, the method comprising: connecting a first reinforcing plate to a front panel, connecting a second reinforcing plate to the first reinforcing plate so that both the first reinforcing plate and the second reinforcing plate extend away from a first side of the front panel, and connecting the second reinforcing plate to another first reinforcing plate.

[0070] These steps may be performed in any order so that the reinforcement panels may be connected together before being connected to the front panel. Alternatively, the first reinforcement panel may be connected to the front panel before the second reinforcement panel is connected to the front panel.

[0071] The second reinforcing plate may also be connected to the front plate. This may be by the same connection means that connects the first reinforcing plate to the front plate. The first and second reinforcing plates may have an additional connection between each other, preferably applied after the first and second reinforcing plates have been connected to the front plate.

[0072] The present invention thus provides a simple and cost effective method for manufacturing fence panels having improved delay times.

[0073] According to a third aspect, there is provided a fence comprising one or more fence panels as described above and two or more fence posts. Preferably, each fence panel is at least partially supported by two fence posts. The surface on which the fence is positioned does not directly support the entire weight of the fence panel.

[0074] The fence panels may be connected to the fence posts by tamper-resistant fasteners. The fence panels may be in contact with the surface on which the fence is positioned, or there may be a gap between the bottom of the fence panel and the surface on which the fence is positioned.

[0075] According to a fourth aspect of the invention there is provided a kit for creating a fence panel as described above, the kit comprising a front panel, one or more first reinforcing panels, one or more second reinforcing panels and connecting means, optionally the kit further comprising two or more fence posts. There may be different connecting means connecting the first reinforcing panel to the front panel than the connecting means connecting the first reinforcing panel to the second reinforcing panel.

[0076] All embodiments of the previous aspects of the present invention are equally applicable to the following aspects of the present invention. BRIEF DESCRIPTION OF THE DRAWINGS

[0084] Figure 7 Shows Figure 6 A top view of a portion of a fence panel. DETAILED DESCRIPTION

[0085] See also Figure 1 , shows a part of a fence panel (100) according to the present invention. The fence panel (100) includes a mesh front panel (101) and a plurality of reinforcing panels, the reinforcing panels including a first reinforcing panel (102) and a second reinforcing panel (103). The fence panel (101) and the reinforcing panels (102, 103) include vertical wires (101a, 102a, 103a) and horizontal wires (102b, 102b, 103b) that intersect and are welded together.

[0086] A plurality of reinforcing plates (102, 103) are each located on one surface of the front plate (101) and extend vertically away from the mesh front plate (101). The first reinforcing plate (102) and the second reinforcing plate (103) are connected to the front plate (101) via a winding member (104), which is more clearly shown in Figures 5A and 5B.

[0087] The wire material of the front plate (101a, 101b) and the reinforcing plate (102a, 102b, 103a, 103b) is made of high tensile strength steel and has a welding strength of 50% and 400N / mm 2 Tensile Strength The core diameter of all vertical wires (101a, 102a, 103a) and horizontal wires (102b, 102b, 103b) is 3 mm.

[0088] The first reinforcing plate (102) is planar and perpendicular to the front plate (101). The second reinforcing plate (103) is perpendicular to the front plate (101) and includes a plurality of bends along the length of the second reinforcing plate (103). Figure 1 As shown, the bend in the second reinforcing plate (103) allows the second reinforcing plate (103) to extend between the two parallel first reinforcing plates (102), thereby crossing the vertical wire (101a) in the front plate (101).

[0089] This structure increases the strength and rigidity of the fence plate, and it has been found that the presence of the bend makes the fence plate highly resistant to cutting tools. In addition, the presence of the bend reduces the amount of space available for an intruder to cut and form an opening that is easy to pass through, thereby increasing the delay time.

[0090] The first reinforcing plate (102) and the second reinforcing plate (103) are connected to form an angle of about 45 degrees, which is formed by the bending portion of the second reinforcing plate (103). Each vertical wire of the mesh front plate (101) is connected to the first reinforcing plate (102) or crossed by the second reinforcing plate (103).

[0091] The angle formed ensures that there is sufficient space between the first and second reinforcing plates for the winding (104), while also minimizing the space available for intruder cutting.

[0092] Multiple portions of the second reinforcing plate (103) extend parallel to and abut against each portion of the first reinforcing plate (102), thereby forming a double layer ( Figure 3 ). Therefore, the first reinforcing plate (102) has a plurality of portions forming a double layer with the second reinforcing plate (103) and has a plurality of portions so that the first reinforcing plate (102) does not contact the second reinforcing plate (103). The portion of the second reinforcing plate (103) abutting against the first reinforcing plate (102) is connected to the front plate (101) via the winding member (104).

[0093] The distance between two first reinforcing plates (102) without a second reinforcing plate (103) therebetween is smaller than the distance between two first reinforcing plates (102) with a second reinforcing plate (103) therebetween.

[0094] To penetrate Figure 1 With the fence panel of the present invention shown, an intruder must first remove multiple parts from the front panel (101). Due to the arrangement of the first reinforcing panel (102) and the second reinforcing panel (103) and the use of the winding member (104), the area available for the intruder to cut and remove is minimized, and therefore only a small area can be cut.

[0095] Secondly, the intruder needs to cut the reinforcing plates (102, 103), which is very difficult due to the narrow spacing provided in the fence panel according to the present invention. In addition, the bend in the second reinforcing plate (103) makes it difficult for the intruder to use a cutting tool to reach the first side of the front plate (101). In addition, the double-layer reinforcing plates (102, 103) in the fence panel (100) increase the difficulty of cutting the wire and damaging the fence.

[0096] Figure 2Shows Figure 1 A rear view of the embodiment shown. Figure 1 Likewise, this embodiment has no rear plate.

[0097] See also Figure 3 , we can see that according to Figure 1 A perspective view of a fence. It can be clearly seen that the first reinforcing plate (102) and the second reinforcing plate (103) are perpendicular to the front plate (101). The reinforcing plates (102, 103) are arranged in a repeating unit, each repeating unit including a second reinforcing plate (103) extending between two first reinforcing plates (102) and connected to the two first reinforcing plates (102).

[0098] The spacing between two first reinforcing plates (102) without a second reinforcing plate (103) therebetween is smaller than the spacing between two first reinforcing plates (102) with a second reinforcing plate (103) therebetween. The second reinforcing plates (103) are bent so that a single second reinforcing plate (103) is parallel to and abuts against the first first reinforcing plate (102), extends away from the first first reinforcing plate (102) at an angle of about 45 degrees, and is then bent again so as to be parallel to and abut against the second first reinforcing plate (102).

[0099] The first reinforcing plate (102) and the second reinforcing plate (103) are both connected to the front plate (101) via a winding member (104), and an additional connecting device (not shown) connects the first reinforcing plate (102) and the second reinforcing plate (103) at the edge away from the front plate (101).

[0100] See also Figure 4 , showing Figure 1 A top view of a portion of a fence of an embodiment of the invention. Figure 4 As can be seen in the figures, the spiral winding (104) provides a loose connection between the first reinforcing plate (102), the second reinforcing plate (103) and the front plate (101).

[0101] Each vertical wire (101a) in the front plate (101) is connected to the first reinforcing plate (102) or crossed by the second reinforcing plate (103). The second reinforcing plate (103) crosses only one wire that is not connected to the first reinforcing plate (102).

[0102] Figure 5a and Figure 5bAn enlarged view is provided to show the connection between the first reinforcing plate (102), the second reinforcing plate (103) and the front plate (101). The front plate (101), the first reinforcing plate (102), and the portion of the second reinforcing plate (103) parallel to the first reinforcing plate (102) are loosely connected via a winding member (104).

[0103] Figure 6 A perspective view of a portion of an alternative fence panel (200) according to the present invention is shown. The fence panel (200) includes a front panel (201) connected to a first reinforcing panel (202) at alternating vertical wires via a winding (204). Thus, every other vertical wire on the front panel (201) is connected to the first reinforcing panel (202).

[0104] The second reinforcing plate (203) extends along the top of the first reinforcing plate (202) and is perpendicular to the first reinforcing plate (202). The first reinforcing plate (202) and the second reinforcing plate (203) are both planar and extend perpendicularly away from the front plate (201). The second reinforcing plate (203) is connected to the front plate (201) and to the first reinforcing plate (202) via a clamp (not shown). A single second reinforcing plate (203) extends along the entire length of the front plate (201).

[0105] Figure 6 The fence panels in the 100% Fence meet the tests outlined in ASTM F2781-15, specifically the test for moderate threats (battery-powered angle disc grinders with delayed entry greater than 10 minutes) and the test for aggressive threats (various tools, such as gas-powered saws and electric disc grinders with delayed entry greater than 5 minutes).

[0106] Figure 7 Shows Figure 6 A top view of a portion of a fence panel (200) is shown, showing the top face of a second reinforcing panel (203) extending perpendicularly to a front panel (201). A first reinforcing panel (202) extends perpendicularly to the front panel (201) and the second reinforcing panel (203) and is connected to the front panel (201) via a winding member (204).
