The present disclosure generally relates to perimeter security systems. More particularly, and not by way of limitation, particular embodiments of the present disclosure are directed to a modular and versatile fencing system based on slotted posts with sliding rails for ease of installation and efficient load distribution.
A fence is a structure that encloses an area, typically outdoors. There are many perimeter fencing solutions available in the market. Generally, a fence around a property or area involves installing in the ground a number of posts spaced apart to receive individual connecting rails and fence panels/wires. A fence differs from a wall in that the fence typically does not have a solid foundation along its whole length.
Current fencing solutions often offer round posts, which are not aesthetically pleasing because posts are integral to a fence system and should integrate with the design instead of sticking out. Furthermore, connecting rails to round posts frequently involves cutting longer lengths of rail pipe and then using clamps to secure the rail at its both ends. Clamping fittings to the post to make mechanical connection of the rails is not aesthetic and is time-consuming. Also, if the post has a hole punched through, water can invade, causing rust or freezing and splitting of the post. The rails may also be scuffed up to the point the powder coated finish of the rails is compromised. Additionally, with larger diameter posts, rails joining at posts are not on the same plane as the face of the framework. This can create a wavy appearance looking down the fence line.
The round posts in traditional fences also pose a problem as to how to give a finished look to line, corner, end, and gate posts. Lack of proper finishing may expose corners and ends of fence lines with spaces for one to begin cutting or climbing.
The individual pieces of rails used for connecting the round posts can reduce the overall strength of the fence against impact. When unwanted breaching occurs, the top rail can become bent, which may compromise the strength of the fence. Furthermore, rails that use sleeves to connect pieces of the rail can physically shift or be forced apart. This not only creates a bad visual appearance, but also reduces the level of security of the barrier.
In addition, the use of washers for fittings or clamping in conventional fences requires a large quantity of washers and does not ensure that the strength is continuous throughout the quantity of washers required.
Still further, the round posts and segmented rails in a traditional fence make it difficult to incorporate impact cables or run electric and optic cables throughout the length of the fence. It is also difficult to incorporate detection devices—such as cameras or monitoring systems—into a traditional fence design.
It is therefore desirable to address the above-mentioned problems of existing fencing systems so that a more robust and secure perimeter fencing may be accomplished. As a solution, particular embodiments of the present disclosure provide for an improved perimeter security system based on a unitized and modular construction method that ties the entire fencing system together and anchors it to the ground through slotted posts. Instead of round posts in existing fence designs, the slotted posts as per teachings of the present disclosure may be square, circular, semi-circular or rectangular. Longitudinal hollow rails are slidably inserted into and through the slots in the posts to provide a continuous rail design that eliminates many of the cuts, clamps, and connections which are necessary when installing most traditional fences. A non-metallic two-part sleeve, which may be made of plastic by way of example, is slidably inserted into the post slots to provide a water resistant, smooth surface to slide the rail through. The full length of the fence is bolted together using the hollow rails, which also allow for incorporation of impact cables as well as electrical and optic cables into the fence system. Additional improvements present in a fencing system as per particular embodiments of the present disclosure are discussed in more detail later below.
In one embodiment, the present disclosure is directed to a fencing assembly that comprises: (i) at least one slotted post to be anchored to the ground; and (ii) at least one hollow rail member to be inserted into and through a corresponding slot in the slotted post. In the fencing assembly, the slotted post includes at least one slot along the length thereof, and the rail member includes a plurality of pre-formed holes. Infill panels of the fence are to be bolted to the rail member through the plurality of pre-formed holes. In one embodiment, the slotted post and the rail member are made of metal. In another embodiment, the rail member may be made of a non-conductive material such as, for example, pultruded reinforced plastic.
As mentioned before, in particular embodiments, the slotted post may be square, circular, semi-circular or rectangular. Furthermore, the hollow rail member may also be substantially square, circular, semi-circular or rectangular in cross-section.
The fencing assembly may further comprise at least one pair of hollow sleeves, wherein each sleeve in a pair of sleeves is to be slidably placed into a respective side of the corresponding slot, and wherein the rail member is to be slidably inserted into the corresponding slot through the pair of sleeves. In one embodiment, the sleeves are made of plastic, such as nylon. The term plastic may include many different materials, but is intended to denote a non-metal material. In another embodiment, each sleeve in the pair of sleeves has a slot-facing end that is angularly tilted to allow for non-horizontal placement of the rail member through the slotted post. The angular tilt may be approximately 20°.
The fencing assembly may further comprise a finish plate to be placed over the slotted post and having a plurality of pre-drilled holes for attaching the finish plate to the slotted post. The finish plate may be made of metal. The finish plate may be directly bolted to a fence panel.
In one embodiment, the present disclosure is directed to a fencing system, which comprises: (i) a pair of slotted posts anchored to the ground and physically spaced apart, wherein each slotted post includes a respective slot along the length thereof; (ii) a hollow rail member inserted into and through a corresponding slot in each slotted post and held in position between the pair of slotted posts; and (iii) a fence panel bolted to the rail member that is inserted into the slotted posts. Throughout the length of the fence, however, it may be necessary at some point to mechanically fasten one rail to the other.
The fencing system may further comprise two pairs of plastic hollow sleeves, wherein each sleeve in a pair of sleeves is placed into a respective side of the corresponding slot sandwiched between the rail member and an internal surface of the corresponding slot. The plastic sleeves allow for slidable insertion of the rail member.
In particular embodiments, finish plates may be mounted on the slotted posts and directly bolted to a portion of the fence panel adjacent to the respective slotted post. The term “finish plate” and “metal plate” are equivalent and interchangeable.
In another embodiment, the present disclosure is directed to a method of installing a fence. The method comprises: (i) anchoring a pair of slotted posts to the ground with a pre-determined distance therebetween, wherein each slotted post includes a respective slot along the length thereof, and wherein each slotted post may be square, circular, semi-circular or rectangular in cross-section; (ii) inserting a slot-specific pair of hollow sleeves in the respective slot of each slotted post, wherein each sleeve in the slot-specific pair of sleeves is snapped into a corresponding side of the respective slot; (iii) inserting a hollow rail member into and through the sleeves in the respective slot in each slotted post, thereby holding the rail member in position between the pair of slotted posts, wherein the rail member includes a plurality of pre-formed holes; and (iv) bolting a fence panel to the rail member through the plurality of pre-formed holes.
Thus, the modular fencing system as per the teachings of the present disclosure provides for a unified curtain wall perimeter barrier. The slotted post- and slidable rail-based approach offers aesthetics, seamless design, ease of installation, and also allows incorporation of impact and electrical/optic cables in the fence system. When fence panels are bolted to the rails, any load or impact to the fence is distributed throughout the entire system, thereby greatly enhancing the strength of the system. Many different types of infill may be used for fence panel sections including, for example, anti-cut and anti-climb mesh options. Diamond Fasteners™ and finish plates provide additional strength to the fencing system. The term Diamond Fastener™ is intended to refer to the metal fastener used to bolt the fencing system.
In the following section, the present disclosure will be described with reference to exemplary embodiments illustrated in the figures, in which:
In the following detailed description, numerous specific details are set forth in order to provide a thorough understanding of the disclosure. However, it will be understood by those skilled in the art that the present disclosure may be practiced without these specific details. In other instances, well-known methods, procedures, components and layouts have not been described in detail so as not to obscure the present disclosure.
Reference throughout this specification to “one embodiment” or “an embodiment” means that a particular feature, structure, or characteristic described in connection with the embodiment is included in at least one embodiment of the present disclosure. Thus, the appearances of the phrases “in one embodiment” or “in an embodiment” or “according to one embodiment” (or other phrases having similar import) in various places throughout this specification are not necessarily all referring to the same embodiment. Furthermore, the particular features, structures, or characteristics may be combined in any suitable manner in one or more embodiments. Also, depending on the context of discussion herein, a singular term may include its plural forms and a plural term may include its singular form. Similarly, a hyphenated term may be occasionally interchangeably used with its non-hyphenated version, and a capitalized entry may be interchangeably used with its non-capitalized version. Such occasional interchangeable uses shall not be considered inconsistent with each other.
It is noted that various figures (including component diagrams) shown and discussed herein are for illustrative purpose only, and are not drawn to scale.
It is observed that the fence panel 18 may be made of any type of material, thereby allowing a user to customize the system to defend against a wide array of threats. In one embodiment, the fence 18 is made of metal, and may be configured to include anti-climb, anti-cut, and many other architectural appearances. In particular embodiments, the posts 11-12 may be spaced apart in such a manner as to accommodate a mesh panel 18 having a given dimension. For example, if the mesh panel 18 has a dimension of 8×12 ft., the posts 11-12 may be separated by 8 feet to snugly accommodate the mesh panel 18. Such larger mesh panels help to eliminate seams, unsightly hardware, and reduce installation time.
The slotted post 22 may be pre-fabricated and specifically designed to anchor the entire fence system to the ground. Unlike traditional fences, the rails, such as the rail 20 in
In particular embodiments, the slotted post 22 may be rectangular or square in cross-section to afford better connectivity for sleeves 27-28 and rail members 20 and also to provide better aesthetics than traditional round posts. Although the rail member 20 is hollow or partially open (for example, to accommodate cables, as discussed below), it also may be substantially rectangular or square in cross-section in certain embodiments. It may also be circular or semi-circular.
As mentioned before, the continuous rail design may eliminate many of the cuts, clamps, and connections that are necessary when installing most traditional fences. In some embodiments, the rail member 20 may be roll formed and may have a highly engineered shape, making it stronger and lighter than traditional rails. The engineered and pre-punched holes 25 may allow for easy attachment of a fence panel, like the fence panel 18 in

It is noted here that the square, circular, semi-circular or rectangular posts as per teachings of the present disclosure may utilize flat top caps, adding to the engineered appearance of the barrier. Furthermore, the modular approach to fence construction as per teachings of the present disclosure permits easy attachment of detection devices—such as surveillance cameras or security lights—to the flat surfaces of rectangular or square posts. Also, the posts may be easily extended to incorporate such detection devices into the fence design.
At block 84, a slot-specific pair of hollow sleeves—like the sleeves 27-28 in
More specifically, in particular embodiments, the plastic sleeves may be inserted per rail per post after the concrete footings have been allowed to sufficiently harden. The rail may be then passed through the slotted posts, connecting segments of a rail with rail connectors (not shown). As noted before, sleeves for corner posts may be mitered, and only one part of the pair of sleeves may be used for end and gate posts. In certain embodiments, ⅜″×1½″ hot dip galvanized carriage bolts may be used to secure rails with rail connectors. The installation of the top and bottom rails may be completed before installing mesh panels.
In one embodiment, starting at a terminal post, a mesh/fence panel may be tilted up against the respective pair of posts and corresponding rails. Once a mesh panel is placed between two posts, it may be desirable to make sure that the direction of its design strands—such as, for example, diamond-shaped strands shown in
As noted before, in particular embodiments, a fence panels may be connected to the rails using 1⅝″ hot dip galvanized carriage bolts and corresponding metallic plate and nut. As mentioned earlier, the panels fit in-between posts. In some embodiments, a long, round-shank screw driver may be used to gain leverage in moving fence panels up as needed to maintain the top line of the fence parallel to the grade. All nuts may be hand tightened. In particular embodiments, the outermost attachment points for mesh to rails may utilize a break-away nut to prevent easy removal and unwanted access.
Subsequently, the finish plates may be connected to the posts and mesh panels. In certain embodiments, each type of post—line, end, corner, and gate post—may receive a finish plate. As mentioned before, finish plates may be pre-drilled to assist in locating fastening points. In connecting a finish plate to a post, the top of the plate may be aligned with the top of the post and tamper proof ¼″×1″ TEK® screws may be used in certain embodiments to secure the finish plate true and plumb to the post. TEK® screws drill their own hole and then tap threads to combine two or more pieces of material. This is done with nothing more than a standard power drill motor. On the other hand, in some embodiments, the finish plates may be connected to the fence panels using ⅜″×1″ hot dip galvanized carriage bolts. In particular embodiments, the splice plates may be Diamond Fasteners™. Final tightening and peening or scarfing of threads may be done after all panels have been installed. As mentioned before, properly-sized post caps may be attached to each post. Also, after the fence system is erected in place, gates and operators may be installed to manufacturer's instructions.
In the preceding description, for purposes of explanation and not limitation, specific details are set forth (such as particular structures, components, techniques, etc.) in order to provide a thorough understanding of the disclosed fencing system. However, it will be apparent to those skilled in the art that the disclosed system may be constructed in other embodiments that depart from these specific details. That is, those skilled in the art will be able to devise various arrangements which, although not explicitly described or shown herein, embody the principles of the disclosed system. In some instances, detailed descriptions of well-known components and construction methods are omitted so as not to obscure the description of the disclosed system with unnecessary detail. All statements herein reciting principles, aspects, and embodiments of the disclosed system, as well as specific examples thereof, are intended to encompass both structural and functional equivalents thereof. Additionally, it is intended that such equivalents include both currently known equivalents as well as equivalents developed in the future, such as, for example, any elements developed that perform the same function, regardless of structure.
Alternative embodiments of the fencing system according to inventive aspects of the present disclosure may include additional components responsible for providing additional functionality, including any of the functionality identified above and/or any functionality necessary to support the solution as per the teachings of the present disclosure. Although features and elements are described above in particular combinations, each feature or element can be used alone without the other features and elements or in various combinations with or without other features.
The foregoing describes a modular perimeter fencing system in which metallic slotted posts are used in conjunction with metallic hollow longitudinal rails of different shapes, thickness, and sizes to support the metallic fence panels in a manner that creates a unified curtain wall perimeter barrier. Plastic sleeves with angularly-tilted ends are inserted into both sides of a slot opening to prevent water intrusion and to facilitate fencing on a slope. The rails are then slidably inserted into and through the sleeves. Thus, rails are held in place upon insertion through the slots without a fastener. The full length of the fence is bolted to the rails to ensure that any load or impact to the fence is distributed throughout the entire system. For additional strength, each fence panel is also through-bolted to metallic finish plates, which are mounted on the slotted posts for seamless and aesthetically-pleasing look.
As will be recognized by those skilled in the art, the innovative concepts described in the present application can be modified and varied over a wide range of applications. Accordingly, the scope of patented subject matter should not be limited to any of the specific exemplary teachings discussed above, but is instead defined by the following claims.
