Description

TECHNICAL FIELD

Apparatus, systems, and methods for a temporary and portable fence suitable for sports and recreational events.

BACKGROUND OF THE INVENTION

Temporary portable fencing for multi-use properties has long been a challenge for owners of public spaces, such as at schools, parks, and similar facilities. This challenge arises for a variety of reasons, including the conflicting requirements of strength and durability versus convenience and ease-of-use. More recently, limited space and budgetary considerations are driving a trend toward multiuse facilities, with the attendant need for flexibility in the placement of the fences. While various temporary or portable fencing systems have been proposed to meet these requirements, there still presently exists a need for a temporary portable fencing system that is at the same time strong and durable while also being easy to erect and disassemble, and highly adaptable as to the placement of the fence. Furthermore, user safety is also an important consideration, especially when the fencing is used in conjunction with sporting events such as baseball, football, and soccer. The invention described herein overcomes many of the deficiencies in prior art temporary portable fencing as will be explained in detail below.

SUMMARY OF THE INVENTION

The portable fence system described herein comprises flexible barrier netting supported at regular intervals between upright rigid mounting poles. In some embodiments, the system uses common, readily available, and inexpensive components such as tubing and flexible netting. In some embodiments the flexible netting is constructed of a synthetic polymer such as polyethylene, polyester, or Nylon®. Netting suitable for use in the instant application is readily available commercially as, for example, knitted polyethylene barrier netting known by various names such as “Roll-A-Fence.” Poles for mounting the barrier netting can be tubing or solid rods having sufficient rigidity to fully support the barrier fencing in an upright position over an expected range of conditions. In some embodiments, the rigid mounting poles can be made from, for example, an aluminum alloy. In yet other embodiments, the barrier netting mounting poles can comprise a synthetic polymer material such as polyvinyl chloride (PVC), Nylon®, or other suitable synthetic polymeric composition. Tubing, either hollow or solid, suitable for the present application is also readily available from commercial suppliers, thereby maximizing convenience and minimizing expense.

In some embodiments, the barrier netting mounting poles are maintained erect on dirt or grass covered areas by attaching them to a specially configured anchor fixture mounted into the ground. In an alternative embodiment, the barrier netting support poles can be maintained erect on dirt or grass covered areas, or on hard surfaces or floors, by anchoring to an anchor fixture having large flat plates that lie entirely above the surface of the area to be enclosed. In order to reduce the chance of damage to the poles and injury to players, the pole anchoring systems described herein may include springs that reversibly flex under impact, or adapters that break upon moderate impact.

The anchoring system according to a first embodiment of the invention comprises an anchor sleeve (102) that is placed into the earth so as to provide a semi-permanent means for receiving and supporting an anchor fixture (202). Anchor sleeve (102) is configured to allow anchor fixture (202) to be removably connected thereto. Anchor fixture assembly (200) comprises anchor fixture (202), further comprising sleeve mount cylinder (106) that, when inserted into anchor sleeve (102), provides sufficient lateral support for maintaining the temporary fence upright. Anchor fixture assembly (200) may further comprise one or more spring mount bolts (204) and spring mount nuts (206), which serve to mount springs (110) to plate (108). Spring (110) in turn is configured to removably attach to and support a flexible netting mounting pole (104) and maintain it in a substantially upright position. In some preferred embodiments, anchor fixture assembly (200) is configured to receive two or more mounting poles.

Anchor fixture assembly (200) may also comprise one or more pole adapters (112) configured for removably connecting mounting poles (104) to springs (110). Anchor fixture (202) may be constructed of a variety of materials, including various plastics or metal alloys having suitable mechanical and environmental durability characteristics as are well known to those of skill in the art. In some embodiments, anchor fixture (202) is constructed using a steel, iron, or aluminum alloy for its components and by welding or soldering the components together. In other embodiments, anchor fixture (202) is made using a cast polymer material such as PVC, polyester, polyethylene, or similar such materials as are currently known, or may become known in the art.

In another embodiment, more suitable to circumstances where it is not desirable or practicable to place semi-permanent anchor sleeves (102) below the playing surface, a portable fencing system (400) is configured with a sufficiently large anchor plate (408) that the temporary fence can be maintained upright under normal circumstances without the aid of anchor sleeve (102) or other such support element placed beneath the playing field surface. In some embodiments, the entire anchor fixture assembly (500) resides above the ground, floor, or other surface upon which the temporary fence is erected. In some cases, anchor plate (408) of the second embodiment may be secured to a floor or hard surface by supplemental means such as screws, bolts, dzus fasteners, etc.

Exemplary embodiments of the apparatus, system, and method sufficient to allow one of ordinary skill to practice the invention are set forth in the drawings and description set forth below.

DETAILED DESCRIPTION

A detailed description of one or more embodiments of the invention is provided below along with accompanying figures that illustrate the principles of the invention. The invention is described in connection with such embodiments, but the invention is not limited to any embodiment. The scope of the invention is limited only by the claims and the invention encompasses numerous alternatives, modifications and equivalents. Numerous specific details are set forth in the following description in order to provide a thorough understanding of the invention. These details are provided for the purpose of example and the invention may be practiced according to the claims without some or all of these specific details. In the interests of clarity, technical material that is known in the technical fields related to the invention has not been described in detail so that the invention is not unnecessarily obscured. As the present invention is intended in some embodiments for indoor use, or where it is desirable or necessary for the mounting system to reside entirely above the surface, the term “ground” as used herein should be understood to include all embodiments of the portable fencing system, whether deployed outdoors or indoors, or on grass, dirt, or on floors or on hard or soft surfaces.

In order to provide user safety in the event of, for example, a sports participant colliding with perimeter fencing, embodiments of a portable fence system, as depicted generally in FIG. 1 and FIG. 4, are provided that allow barrier netting mounting poles to tilt or collapse upon impact. Referring now to FIGS. 1-3, there is presented a portable fencing system (100) according broadly to a first exemplary embodiment wherein the fence is supported in an upright position with the aid of an element placed into the ground. In some preferred embodiments, mounting pole (104) is allowed to tilt upon impact with the pole or its associated barrier netting (116) by interposing a spring (110) between the bottom of pole (104) and anchor fixture (202). In some alternative embodiments, fencing system (100) may not include spring (110) or adapter (112), or may include other elements as will be presented below.

Portable fencing system (100) according to this first exemplary embodiment of the invention comprises an anchor sleeve (102) that is placed into the ground to provide a semi-permanent means for receiving and supporting anchor fixture (202). Anchor sleeve (102) is configured to allow anchor fixture assembly (200) to be removably attached thereto. Anchor fixture (202) comprises sleeve mounting cylinder (106) that, when inserted into anchor sleeve (102), provides sufficient lateral support for maintaining mounting poles (104) and associated barrier netting (116) in a substantially upright position. Anchor fixture (202) further comprises, in this exemplary embodiment, two springs (110) that are affixed to plate (108) by bolts (204) and nuts (206). In order to facilitate secure attachment, the lower coils of springs (110) are wound with smaller inside diameters so as to provide a suitable purchase for nuts (206), while the upper inside diameters are large enough to allow clearance for the nuts (206), thereby providing temporary but secure attachment to mounting pole (104), either directly or by interposing pole adapter (112).

Referring now to FIG. 1, flexible barrier netting (116) is attached to a barrier frame comprising netting frame poles (114) that are dimensioned in width according to the placement of anchor sleeves (102), and in height according to its intended use. The barrier frame width is dimensioned so as to allow for easy portability by one or two people, and in height according to the activity to which it is applied. In some applications, the barrier frame has a width of at least six feet and in other applications, a width of at least nine feet. In some applications, the barrier frame has a height of at least three feet and, in other applications, a height of at least six feet. In a modification of the first embodiment, the barrier frame can be omitted and barrier netting (116) simply attached at each end to two vertically upright adjacent mounting poles (104). Considerations as to the material and dimensions of mounting poles (104) and netting frame poles (114) include strength, weight, and cost. It has been found that mounting poles constructed of extruded 6061 or 6063 aluminum alloy pipe or tubing having outside diameters in the range 1.0 inch to 1.5 inch, are suitable for this application. Mounting poles with wall thicknesses in the range 0.05 inch to 0.125 inch have been found to be satisfactory for the typical range of portable fence height and width dimensions as described herein. In some embodiments, mounting pole (104) has an outside diameter of 1.25 inch with a wall thickness of 0.06 inch. In other embodiments, mounting pole (104) has an outside diameter greater than about 1 inch and a wall thickness greater than about 0.05 inch.

Anchor sleeves (102) are preferably positioned in the ground according to a desired perimeter to be defined by the portable fence, and are spaced according to the widths of the sections of flexible barrier netting they are intended to support. Being relatively unobtrusive, anchor sleeves (102) can remain embedded in the ground essentially indefinitely, thereby allowing for easy removal and subsequent quick redeployment of anchor fixture assembly (200) and other elements of the present portable fencing system. Anchor sleeves (102) can be constructed using various commercially available pipe or tubing including aluminum or galvanized iron pipe. It has been found that PVC pipe is also well suited for this application. More specifically, nominal 1.250 inch schedule 40 PVC pipe has been found very suitable, but sizes somewhat smaller or larger in diameter can also be used. Anchor sleeve (102) can be in the range of 12-24 inches and more favorably in a range of 15-21 inches in length. Anchor sleeve (102) can be pounded into the ground, or holes in the ground suitable for inserting anchor sleeve (102) can be made by various appropriate and well known methods such as using a power drill and auger bit. A cap or plug can be inserted on the upper end of anchor sleeve (102) to prevent it from filling with debris and to facilitate finding it more easily.

Referring now to FIG. 2, there is shown in exploded perspective view anchor fixture assembly (200) according the first embodiment as in FIG. 1 comprising an anchor fixture (202), having a sleeve mounting cylinder (106), which provides the appropriate lateral rigidity required to support one or more fence mounting poles (104) in an upright position during normal use. Anchor fixture assembly (200) may further comprise one or more mounting springs (110) and associated mounting pole adapters (112), which are configured to support one or more mounting poles (104). Mounting spring (110) may be configured such that at the bottom end the spring is partially closed so as to allow the spring to be bolted directly to plate (108) using bolt (204) and nut (206). An optional pole adapter (112) can be configured so as to provide mechanical attachment of mounting pole (104) to spring (110). As such, pole adapter (112) can fit snuggly into mounting pole (104) at its upper end, and fit snuggly into spring (110) at its lower end. A raised portion between the top and bottom ends of pole adapter (112), as is indicated in FIG. 2, helps correctly locate pole adapter (112) at the desired depths into mounting pole (104) and spring (110), respectively.

Pole adapter (112) can be configured to couple mounting pole (104) to spring (110). In this embodiment, pole adapter (112) may be configured with a first length and first diameter pertaining to the upper end portion for secure, but removable, insertion into mounting pole (104), and with a second length and second diameter pertaining to a lower end portion for secure, but removable, insertion inside spring (110). The length of said upper end portion, which is adapted for insertion inside mounting pole (104), can be in the range 2-5 inches with 3.5 inches being a satisfactory length in many cases. The length of said lower end portion of adapter (112), which is adapted for insertion inside spring (110) can be in the range 0.75-1.5 inches with about 1.0 inch being a length that has been found to be suitable for many applications. Said raised portion may be in the form of a raised collar that extends circumferentially around pole adapter (112), or may be in the form of discrete raised portions. The length of said raised portion should be the minimum necessary so as to not unnecessarily raise the bottom of the fence panels above the playing surface. It has been found that a length of 0.125 inch is sufficient in most cases. The outside diameter of the raised portion can extend to any convenient dimension, but generally equal to or somewhat less that the larger of the outside diameters of mounting pole (104) or spring (112) is appropriate. A diameter of 1.6 inches has been found satisfactory, but larger or smaller diameters in the range 1.4-1.8 inches can be used in most cases.

Pole adapter (112) can be formed of a variety of materials including various aluminum alloys, various polymeric materials such as Nylon®, Delrin®, or glass-filled composites thereof. Other suitable materials that are known, or may become known, to those of skill in the material and mechanical arts are also included within the scope and spirit of the invention. Pole adapter (112) may be in the form of a solid cylinder or in the form of a tube having a wall thickness appropriate to withstand the expected lateral forces without deforming or breaking. It has been found that a hollow bore adapter with a wall thickness of 0.175 inch is suitable for the range of fencing system dimensions considered herein, but thicknesses in the range of 0.125 to 0.35 may be suitable for some applications. In some embodiments, pole adapter (112) is configured to break when a lateral force somewhat less than sufficient to cause permanent damage to mounting pole (104) is applied. In other embodiments, pole adapter (112) is adapted to break when a lateral force somewhat less than sufficient to result in injury to a player is applied. In these alternative embodiments, pole adapter (112) may be in the form of a tube with a wall thickness such that it fails at a lateral load level less than that at which mounting pole (104) would fail, or at a lateral load level less than that at which injury to a player might occur. Pole adapters (112) can be further configured so as to release from their respective connections when an excessive lateral force is applied, thereby reducing the likelihood of damage to mounting pole (104) or spring (110). Exemplary pole adapters (112) of FIG. 2 are but one of many configurations that would occur to one of skill in the art and which would still fall within the spirit and scope of the invention.

Anchor fixture (202) is advantageously constructed of a suitable metal or metal alloy material that is rendered resistant to the environmental effects of prolonged placement in the ground. For example, anchor fixture (202) can be constructed by welding or soldering a metal sleeve mount cylinder (106) to a metal plate (108). The metal used for plate (108) and sleeve mount cylinder (106) may be, for example, steel, iron, or alloys thereof. Sleeve mount cylinder (106) should advantageously have an outside diameter that allows easy insertion into anchor sleeve (102), and have a wall thickness that provides adequate strength to resist bending under lateral load. It has been found that nominal 1.0 inch schedule 40 steel pipe, having an outside diameter of approximately 1.375 inch, and an inside diameter of approximately 1.049 inch, is suitable for anchor sleeve (102) in this application. The length of sleeve mount cylinder (106) can be equal to or somewhat less than the length of anchor sleeve (102), so as to allow plate (108) to rest solidly on the playing surface. If, for example, anchor sleeve (102) is 15 inches in length, then sleeve mount cylinder (106) can be in the approximate range 11-14.5 inches in length. It has been found that plate (108) can be a steel plate having dimensions of approximately 9 inches in length, 5 inches in width, and with a thickness 0.1875 inch, which provides adequate stability for a portable fence having a height in the range of 6 feet to 8 feet. In order to resist corrosion, a metal anchor fixture (202) can be painted, powder coated, plated, chemically treated, or otherwise coated according to well-known methods and materials. Anchor fixture (202) can also be constructed by other methods and using other materials, such as for example by forming or casting it of a composite or polymeric material.

Referring still to FIG. 2, springs (110) are advantageously constructed of heavy gauge steel having sufficient bending stiffness to provide suitable lateral support to their respective mounting poles (104). The lateral stiffness of mounting springs (110) should be such that they maintain the fence poles upright under the expected range of circumstances, but not so stiff as to cause its supported fence pole (104) to bend irreversibly beyond its elastic limit if impacted by, for example, a sports participant. In one variation of the first embodiment, adapter (112) can be eliminated and the inside diameter of spring (110) made compatible with the outside diameter of mounting pole (104) so as to allow a snug, but removable, fit of mounting pole (104) directly into spring (110). In this variation of the first embodiment, the extension of mounting pole (104) below the “T” connector, or some other suitable obstruction, can be used to limit the depth of insertion of mounting pole (104) into spring (110), thereby providing both secure connection to, and adequate flexibility for, spring (110). In some embodiments the anchor fixture assembly (200) achieves a low profile for netting frame pole (114) and attached netting (116) above the playing surface such that the gap between the bottom of the netting frame pole (114) and ground level of the earth or floor surface is minimized.

Spring (110) may be used without modification in one or more of the various exemplary embodiments of the invention as described herein. Spring (110) can be constructed from roundbar having a range of diameters and materials. In certain embodiments, spring (110) can be constructed of 0.343 inch solid steel roundbar, such as ASTM material grade A500 or A501 wound with a 2.0 inch outside diameter and having an inside diameter of 1.3 inch, which inside diameter is selected to provide an interference fit with adapter (112). Alternatively, adapter (112) can be configured to provide an interference fit with spring (110). An interference fit is defined as being approximately in accordance to the ANSI B4.1 standard for a FN-1 light drive fits. Spring (110) can be constructed without gaps between turns, and the number of turns can be such as to give a length of spring (110) in the range 2.5-3.5 inches. These dimensions have been found to be suitable for a fence having mounting poles (104) in the range 4.5-8.0 feet in height. Suitable dimensions can be easily configured for shorter or taller fences, or for applications requiring increased or decreased lateral stiffness as is readily discernable to those of skill in the art in view of the exemplary embodiments presented herein.

Referring now to FIG. 3, there is shown in cross-sectional view a fully assembled portable fence mounting system (100) according to the first exemplary embodiment as presented in FIG. 1 and FIG. 2. When erecting fence mounting system (100) for the first time on a suitable playing field, anchor sleeves (102) are inserted into the ground at suitable intervals, determined by the length of netting frame poles (114), along the desired perimeter of the portable fencing system (100). At some time prior to erecting portable fencing system (100) for the first time, a suitable number of barrier netting panels are assembled or procured pre-assembled from a third party, each panel comprising flexible barrier netting (116) supported by two vertically oriented mounting poles (104), two horizontally oriented netting frame poles (114), and their four respective connectors. The number of panels required depends on the length of barrier fencing needed. After assembling a panel frame, flexible barrier netting (116) is affixed by suitable means such as, for example, cable ties to fence mounting poles (104) and, if included, one pole adapter (112) is attached to each mounting pole (104). A spring (110) corresponding to each mounting pole (104) is affixed to each anchor fixture (202), either by bolting or by otherwise permanently or semi-permanently attaching them to plate (108). When it is desired to erect the portable fencing system (100), each assembled anchor fixture (202), comprising springs (110), plate (108), and sleeve mounting cylinders (106), is inserted into its respective anchor sleeves (102) such that each anchor fixture plate (108) rests flat on the playing surface.

The configuration of portable fencing system (100) permits it to be quickly and easily dismantle by simply first lifting the fencing panels off of their respective anchor fixtures (202), and then removing the anchor fixtures (202) from their respective anchor sleeves (102). When disassembled, the only portion of the portable fence system of the present invention that remains in place are anchor sleeves (102), which presents only an inconsequential visual, physical, and environmental impact. When it is desired at a later time to reassemble the portable fence, having the anchor sleeves left in the ground allows the portable fence of the present invention to be easily and quickly erected again by simply reversing the above disassembly procedure. By arranging various configurations for the placement of anchor elements in a given recreation or work area, the portable fencing system of the present invention can serve a variety of uses. For example, the present portable fencing system makes it feasible to accommodate various sporting events in a short period of time. Thus, for example, a baseball game can be scheduled in the morning and, after relocating the portable fence, a soccer game in the afternoon.

Referring now to FIG. 4, there is presented a perspective view of an anchor fixture assembly (400) according to a second exemplary embodiment of a portable fencing system that is broadly similar to that described in the first embodiments, but configured for use on indoor surfaces, hard outdoor surfaces, or where, for any reason, placing the anchor fixture completely above the playing surface is preferred. In this alternative embodiment, the area of the anchor plate (408) may be increased relative to the first embodiment so as to provide, without the presence of an anchor sleeve (102) or sleeve cylinder (106), sufficient lateral support for the fence poles.

In this alternate embodiment, portable fence anchor system (400) comprises an anchor plate (408) to which is affixed, similarly to anchor plate (108) of the first embodiment, one or more springs (110). Any of the previously described mounting methods, such as bolting then to plate (408) as used in the first embodiment can be utilized. Plate (408) can be enlarged relative to plate (108) of the first embodiment. It has been found that a steel plate having dimensions of 33 inches in length, with a width of 10 inches and a thickness of 0.375 inch provides adequate stability for a portable fence having a height in the range 6-8 feet. Other dimensions can be used, as would occur to one of skill in the related arts. For example, lengths in the range 25-40 inches, widths in the range 6-14 inches, and thicknesses in the range 0.25-0.5 inches may be suitable for some applications.

Referring now to FIG. 5, there is presented an exploded perspective view of anchor fixture assembly (500), corresponding generally to FIG. 2 of the first embodiment, according to the second exemplary embodiment of the invention. Other than the absence of anchor sleeve (102) and sleeve mount cylinder (106), description and features described above relative to anchor fixture assembly (200) of the first embodiment apply equally to anchor fixture assembly (500). FIG. 6, which corresponds to FIG. 3 of the first embodiment, presents in cross-sectional view a fully assembled portable fence mounting system (400) according to the second exemplary embodiment as presented in FIG. 4 and FIG. 5.

Referring now to FIG. 7, there is presented an exploded perspective view an anchor fixture assembly according to a highly simplified alternative of the first embodiment in which mounting poles (104) are inserted directly into mounting pole cups (704) that are fastened to sleeve mount cylinder (106). As in the previously described embodiments, sleeve mount cylinder (106) is inserted into anchor sleeve (102). Mounting cups (704) can be attached to sleeve mount cylinder (106) by various methods, including welding, soldering, riveting, or any of the methods that would be obvious to one having an ordinary level of skill in the art. In other regards, the fence system of this alternative embodiment is compatible with the previously described embodiments, including the size and construction of the fence panels, mounting poles.

FIG. 8 presents yet another embodiment that is a variation of the first embodiment in which the function of anchor sleeve (102) is served by surface fastener such as an anchor screw (806). This alternative embodiment is more suitable for occasions where a portable fencing system is needed in a new location, or where it is not convenient or advantageous to insert the anchor sleeves (102) into the ground. While anchor screw (806) is shown as a discrete element in FIG. 8, it may also be affixed permanently to anchor plate (808). The threads of anchor screw (806) permit a convenient means for inserting into the ground using, for example, a drill motor or by hand. Alternatively, anchor screw (806) can be a smooth cylinder or tube affixed to anchor plate (808) that is simply driven into the ground using a hammer or similar method, or into a hole previously augered into the ground. As with previously described embodiments, those descriptions of the various features that are in common with this particular embodiment, so as for example spring (110) and adapter (112), are also generally applicable to this particular embodiment.
