COMBINED BACKSTOP NET DEVICE AND ASSOCIATED SYSTEMS AND METHODS

Abstract

Various backstop net system embodiments have at least one wall, at least two poles, and at least two connecting sleeves that connect the wall (and any adjacent walls) and the poles. Additionally, certain systems include a net that extends between and is connected to two adjacent poles and moves between deployed and retracted positions within a cavity in the wall. Many exemplary implementations of these systems include multiple walls, poles, and connecting sleeves that can be easily installed in a modular manner to create a backstop for a playing field, such as a softball or baseball field.

Description

[Technical field]

[0001] <Cross-reference to related applications> This application claims the benefit under 35 U.S.C. § 119(e) to U.S. Provisional Application No. 63 / 336,566, entitled "Combination Backstop and Netting Apparatus and Related Systems and Methods," filed on April 29, 2022, the entirety of which is incorporated herein by reference.

[0002] Various embodiments herein relate to sports field structures, and more specifically, to backstop netting systems for use on various types of playing fields, including softball and baseball fields. [Background technology]

[0003] Known methods for the installation of sports backstop netting systems are highly customized, site-specific, and, as a result, highly labor-intensive. Typically, large nets and excess structural components (such as lumber) are shipped to size and cut and / or trimmed on-site during installation. The customized nature of these known systems and methods typically results in slow and error-prone installations, which, in addition to being very expensive, can produce inaccurate, unprofessional, and / or inconsistent backstops between fields or venues.

[0004] Additionally, while some more recent backstop systems have fewer poles (to improve line of sight), these systems have issues with pole integrity (e.g., in case wind or weather conditions weight down the netting) and with less mounting surface for optional value-added devices (video cameras, speed guns, microphones, etc.).

[0005] In addition, known backstop netting systems generally lack modularity and are therefore not designed to be modified or adjusted after installation, making subsequent modifications cumbersome and expensive, and such known systems also do not allow for removal or storage of the netting, resulting in the netting being exposed to the elements until it breaks - which increases the cost of the system when the netting must be replaced prior to its useful life.

[0006] There is a need in the art for improved methods and systems for the installation and maintenance of sports field backstop netting systems. Summary of the Invention

[0007] Described herein are various backstop netting systems, as well as methods of installing such systems.

[0061] Various embodiments herein relate to a backstop netting system for use on various types of playing fields, including softball and baseball fields. A particular implementation is a modular system having connectable wall sections and poles with a retractable netting such that the system allows for easy installation and modification.

[0062] 1A-1E show one exemplary embodiment of a combination backstop and net system 10. As shown, the system 10 has a backstop 12 made up of multiple modular wall units 14 to which multiple poles 16 are attached via multiple sleeves 18. In the particular system 10 shown, the backstop 12 has eight wall units 14 with nine poles 16 and nine corresponding sleeves 18. Alternatively, the backstop 12 can have any number of wall units 14, poles 16, and sleeves 18 depending on the desired size. In various implementations including the system 10 as shown, the system 10 is installed adjacent to a softball or baseball field 20, and the backstop 12 is in an angled configuration with the field 20 located on the concave side of the backstop 12 and the viewer area 22 located on the opposite (or convex) side. Alternatively, due to the modular nature of the system 10, depending on the type of sports field, the backstop 12 can have any configuration, including a straight (non-angled) configuration.

[0063] According to some embodiments, a concrete pad 24 can be added to the spectator side of the net 12, as best shown in Figures 1A, 1C, and 1D. The concrete pad 24 can help secure and stabilize the net 12 in place while providing a walkway for spectators along the net's side. That is, as described in more detail below, the net's side can function as a concrete form for that side when concrete is poured. Figure 1B shows the net 12 prior to the addition of the pad 24. Alternatively, the concrete pad is not added.

[0064] 1E (and described in further detail below), each sleeve 18 provides both stability for and connection of the major components therein to backstop 12. More specifically, each sleeve 18 is positioned in the ground and connected to an end of an adjacent wall section 14 to receive a pole 16 within sleeve 18.

[0065] An exemplary wall section 14 is shown in Figures 2A-2C, according to one embodiment. The wall is comprised of an elongated wall body 30 having a first (or inner) side 32, a second (or outer) side 34, and end sections (or "columns") 36 disposed at each end of the body 30. As shown in Figure 2C, the inner side 32 has two large openings 38A, 38B defined in the side 32 that provide access to an interior cavity 40 defined between the two sides 32, 34. In addition, the wall body 30 also has a vertical support 42 disposed within the cavity 40 and an upper opening (or upper slot) 46 defined in the upper surface 44 of the body 30. As will be described in more detail below, the slot 46 can be used to receive a net 120 when retracted into the cavity 40 of the wall body 30. 2C, each of the vertical supports 42 has a vertical slot 48 capable of receiving the net 120 when it is positioned within the cavity 40, as well as at least one opening 50 defined therein, each of which can receive a conduit (such as conduit 86), an electrical cord, or the like, as will be described in further detail below. Additionally, each wall section 14 has two support structures (or "feet") 52 attached to a bottom portion of the section 14. The two legs 52 are located near either end of the wall 14, and the legs 52 can be used to ensure that the wall 14 is positioned in an upright position during the installation process, as will be described in further detail below.

[0066] As best shown in Figures 2C, 4A, and 4B, end columns 36 are attached to or integral with each end of the wall body 30. Each has a vertical shaft 60 defined therethrough, with openings 62, 64 at the top and bottom of the column 36, respectively. In certain embodiments, each column 36 has one or more mounting structures 66 that allow that column 36 (and thus the end of the wall body 30) to be attached to the mounting sleeve 18 (and thereby the pole 16), for example, via one or more removable pins (not shown), as described in further detail below. In a particular embodiment as shown in Figure 4B, the mounting structure 66 is a cylindrical pin receiving structure 66 that extends from the column 36 as shown and mates with or aligns with a similar cylindrical pin receiving structure 106 extending from the sleeve 18. Alternatively, any known mounting structure or feature that can be used to attach the end of the wall body 30 to the sleeve 18 can be used.

[0067] In some embodiments, best shown in FIG. 4A, each end column 36 can have one or more conduit openings 68 defined on the outside of the column 36. According to certain embodiments, the openings 68 are arranged to allow one or more flexible conduits (or other elongated components as discussed elsewhere herein) to pass through the openings 68, such that they can exit one end column 36 via the openings 68, extend around the pole 16, and return to the end column 36 on the other side of the pole 16 via the openings 68. Thus, any number of flexible conduits (as discussed elsewhere herein) can extend around the entire length of the back net 12 by exiting each wall section 14 on the spectator side and extending into an adjacent wall section 14 via the openings 68. In the particular exemplary column 36 shown, there are five conduit openings 68. Alternatively, the column 36 can have one, two, three, four, six, or any other number of openings 68. In further alternatives, the column 36 may have no such openings. In addition, as best shown in Figures 4A and 4C, certain embodiments of end columns 36 can include ball return openings 70 defined on both the inside and outside of columns 36, allowing customers or others to return balls to the playing field (e.g., in the event that a dirty ball travels over system 10 and lands on the spectator side of backstop 12). In such embodiments, corresponding openings are provided in any removable pad sections (such as section 54, as discussed elsewhere herein) on the inside of backstop 12 and in covers 160A, 160B (as discussed elsewhere herein) on the outside. Alternatively, no such openings are provided.

[0068] Returning to Figures 2A and 2B, certain implementations of the wall section 14 can include various additional components for use in enhancing the features of the system 10 and the arena in which the system 10 is disposed. For example, the wall section 14 can have two electrical outlets 80 mounted on the exterior 34 of the wall body 30 (e.g., for patrons to access to charge their personal devices). One exemplary embodiment of the outlets 80 is further illustrated in Figures 3A and 3B. The outlets 80 are positioned on the exterior 34 with the front of the outlets 80 facing the spectator side, as illustrated in Figure 2B, and the rear of the outlets 80 extends into the cavity 40, as illustrated in Figure 2A. Each outlet 80 can have a removable outlet cover 82, as illustrated in Figures 2B and 3B. Alternatively, the wall section 14 can have one individual outlet, three individual outlets, or any number of individual outlets.

[0069] Additionally, as best shown in FIGS. 2A and 2C, the cavity 40 may also include a junction box 84 and a conduit 86 attached to the junction box 84, such that any electrical cords attached to the junction box 84 may extend through the conduit 86. The junction box 84 may be utilized to provide power to any number of various accessories or optional components attached to or associated with the wall section 14. As mentioned above, the conduit 86 may be disposed through the opening 50 in the vertical support 42, as shown. Alternatively, various insulated electrical cords and / or wiring may be disposed through the opening 50 and coupled to the appropriate box 84 without the need for a conduit 86. As shown, the wall 14 has two junction boxes 84. Alternatively, the wall 14 may have one, three, or any number of junction boxes 84, depending on the number of desired accessories or components to be coupled to such box 84.

[0070] The conduit 86 may be any known conduit, either flexible or rigid. For example, in one particular embodiment, the conduit 86 may be either mid-wall steel conduit (rigid) or oil-resistant liquid-tight flexible metal conduit (flexible) available from McMaster-Carr of Elmhurst, Illinois. Additionally, the junction box 84 may be any known enclosure for electrical components. For example, in one particular embodiment, the junction box 84 may be a weather-resistant enclosure available from McMaster-Carr of Elmhurst, Illinois.

[0071] As discussed above and as best shown in FIG. 2C, the field side 32 of each wall section 14 may have two openings 38A, 38B providing access to the cavity 40 therein, according to certain embodiments. Alternatively, the field side 32 of the wall section 14 may have one opening, three openings, or any number of openings to allow access to the cavity 40. These embodiments may have padding sections 54 removably attached to the field side 32, as best shown in FIGS. 1C and 1D. In the illustrated exemplary embodiment, there are three removable padding sections 54 attached to each wall section 14. Alternatively, the wall section 14 may have one, two, four, or any number of padding sections 54 removably attached thereto. According to some implementations, the spectator side 34 has no such openings or padding, as best shown in FIG. 2B. Alternatively, the spectator side 34 of the wall 14 may have one or more openings. In a further alternative, the spectator side 34 may have one or more removable pad sections that are removable only from the field side or that are attached to prevent spectators from removing those sections. In a further embodiment, the spectator side 34 of the wall 14 may have a decorative front or surface for markings or advertising.

[0072] The padding section 54 may be any known sports field wall padding. For example, in one particular embodiment, the padding section 54 may be tailored backnet padding available from Fieldwallpads,com of Clarion, Iowa.

[0073] As best shown in FIG. 12, according to certain embodiments, each wall section can also have an adjustable and removable turf attachment structure 220 attached to the field side 32 of the wall 14. The turf attachment structure 220 can be any structure that is vertically adjustable on the wall 14 and capable of attaching field turf located on the playing field. In the particular exemplary embodiment as shown, the turf attachment structure 220 is an L-shaped structure 220 having a vertical portion 220A that is adjustably and removably attached to the field side 32 of the wall 14 and a horizontal portion 220B that extends away from the wall 14. In this exemplary implementation, a commercially available plastic "nail gun" 222 is attached to the L-shaped structure 220, allowing turf to be attached to the structure 220 via the nail gun. Alternatively, any adjustable and removable structure that can be used to allow turf to be attached to the wall section can be used.

[0074] Various wall section 14 embodiments disclosed or contemplated herein can have a length of about 24 feet and a height of 3 feet. Alternatively, the length of the wall 14 can range from about 12 feet to about 24 feet, depending on the desired overall size of the backstop 12. Additionally, the height of the wall 14 can range from about 2 feet to about 4 feet. The wall section 14 can be made, for example, of commercial grade steel, aluminum, or alloys thereof. Additionally, the wall section 14 can be formed, for example, using modern machining, laser cutting, and / or forming techniques and processes. If desired, the parts can be galvanized (e.g., hot dipped), power coated, or further treated (e.g., for weather resistance). Alternatively, the wall section 14 can be made from any known material and via any known process for use in sports backstops and barriers.

[0075] Additionally, various pole 16 implementations disclosed or contemplated herein can have a length of about 30 feet. Alternatively, the length of the pole 16 can range from about 20 feet to about 40 feet, depending on the desired overall size and height of the backstop 12. Additionally, each pole 16 can have a width of about 6 inches and a depth of about 6 inches. Alternatively, the width and depth of the pole 16 can vary by any known amount as needed / desired. The poles 16 can be made, for example, of commercial grade steel, aluminum, carbon fiber, or alloys thereof. Additionally, the poles 16 can be formed, for example, using modern machining, laser cutting, and / or molding techniques and processes. If desired, the parts can be galvanized (e.g., hot dipped), power coated, or further treated (e.g., for weather resistance). Alternatively, the poles 16 can be made from any known material and via any known process for use in sports backstops and barriers.

[0076] 4A and 4B, certain system 10 embodiments can also have an elongated mounting body (or "sleeve") 18 that couples the two wall sections 14 to the pole 16. In some embodiments, the sleeve 18 allows some freedom of movement of the wall section 14 relative to the pole 16 to which it is attached, thereby providing some adjustability and the ability to correct the positioning of the wall 14 and pole 16 during installation (e.g., if site conditions are not as expected, the ground is not level, etc.).

[0077] As best shown in Figures 1E, 4A, and 4C, the sleeve 18 has an open shaft or elongated cavity (not shown) defined through the length of the sleeve 18, with one end (the "top") of the sleeve 18 having an opening 102 in communication with the shaft or cavity. Thus, the pole 16 may be inserted into the shaft through the opening 102 such that the pole 16 is disposed within the sleeve 18 and extends from the opening 102. According to one embodiment, the elongated cavity of the sleeve 18 (not shown) that may receive the pole 16 extends from the top opening 102 to an internal structure 108 disposed within the cavity of the sleeve 18 and blocks further progression of the pole 16 within the sleeve 18. In one particular embodiment, the internal structure 108 is comprised of four angle irons 108 (three of which are seen in Figure 4C) that extend from an exterior area into the cavity of the sleeve 18, thereby providing contact points for the end of the pole 16 within the sleeve 18. Alternatively, the internal structure 108 may be any known structure, such as, for example, a lip, a flange, or any other structure or object that is fixed in place within the sleeve 18 and prevents the pole 16 from extending further within the sleeve 18.

[0078] Additionally, the sleeve 18 may have two sets of set screws or other adjustable mounting devices 110, 112 that may be used to position and secure the pole 16 in place relative to the sleeve 18. More specifically, as described in more detail below, each of the set screws 110, 112 may be separately adjusted to modify the positioning of the pole 16 to ensure that the pole 16, and therefore the entire backstop 12, is level.

[0079] Additionally, as discussed above, certain embodiments of the sleeve 18 have one or more attachment structures 106 disposed on either side of the sleeve 18 that allow the sleeve 18 to be attached to the wall portion 14. In certain embodiments as shown in FIG. 4B, the attachment structures 106 are cylindrical pin receiving structures 106 that extend from the sleeve 18 as shown and mate or align with similar cylindrical pin receiving structures 66 extending from the wall portion 14 attached to each side of the sleeve 18. More specifically, there are four such pin receiving structures 106 on each side of the sleeve 18 (for a total of eight), with two upper structures 106 and two lower structures 106. Alternatively, any known attachment structure or feature that can be used to attach the end of the wall body 30 to the sleeve 18 can be used.

[0080] Each sleeve 18 embodiment disclosed or contemplated herein can have a length of about 2 feet. Alternatively, the length of the sleeve 18 can range from about 2 feet to about 12 feet. Additionally, the inside dimensions of the shaft defined by the sleeve 18 can have a width of about 7 inches and a depth of about 7 inches. Alternatively, the width and depth can range from about 4 inches to about 12 inches. In a further alternative, the inside dimensions can be any width and depth that allows the pole 16 to be placed therethrough. The various sleeve embodiments 18 herein can be made of the same materials and via the same processes as the wall section 14 or pole 16, as described above.

[0081] According to some embodiments, the sleeve 18 provides some freedom of movement between the coupled wall section 14 and the pole 16. More specifically, the mounting structure 106 has some limited freedom of movement relative to the wall section 14 to which it is attached, so that some adjustment is possible. Furthermore, the set screws 110, 112 also allow some adjustment of the pole 16 relative to the sleeve 18 in this case. In this way, during assembly of the backstop 12, the various components have some freedom of movement, thereby ensuring some amount of adjustability so that the various components can be positioned and attached relative to each other to optimize the positioning and stability of the entire backstop 12.

[0082] As shown in Figures 5A and 5B, various system 10 embodiments herein include deployable and retractable net sections 120 dimensioned to fit between and be attached to poles 16 attached to opposite ends of corresponding wall sections 14. In other words, the net sections 120 are modular in the same manner as the remaining components of the system 10. Thus, each section 120 has a width substantially similar to the length of the corresponding wall section 14, such that the net section 120 extends between and is attachable to opposing poles 16. Additionally, various net section 120 embodiments herein are movable between a deployed position as shown in Figure 5A and a retracted position as shown in Figure 5B, in which the net section 120 is disposed within the wall section 14 as described above.

[0083] According to some embodiments, the netting 120 may be any known netting for use in conjunction with a baseball or softball backstop. For example, the netting 120 may be Ultra Cross® Knotless Netting, available from Sports Field Specialties, Inc. of Delhi, New York.

[0084] In one embodiment best shown in Figures 5A-7, the net 120 is movably attached to each pole 16 via a mounting track 122 on the pole 16. More specifically, each pole 16 has two mounting tracks 122, one on each side of the pole 16 facing an adjacent pole 16. Alternatively, in certain embodiments, the poles 16 intended to be positioned at each end of the backstop 12 may have a mounting track 122 on only one side of the pole 16. According to one embodiment best shown in Figures 6B and 7, the track 122 is comprised of an elongated track body 124 having a flow passage 126 defined therein. The flow passage 126 has a narrow portion 126A defined by a lip 130 on an exterior surface 128 of the track body 124, and a wider portion 126B defined in the body 124 that helps form the lip 130 on either side of the narrow flow passage 126A, as best shown in Figure 7A.

[0085] 7A, slidably mounted to this embodiment of the track 122 is a slidable attachment device 140 that can be coupled to a portion of the net 120, thereby coupling the net 120 to the track 122. More specifically, in one implementation, the slidable attachment device 140 has a slidable body 142 to which an attachment loop 144 is attached. The slidable body 142 is sized to fit within the wider portion 126B of the flow path 126, but has a diameter that is greater than the width of the narrow flow path 126A. Thus, the slidable attachment device 140 is mounted relative to the track 122 such that the slidable body 142 is slidably positioned within the wide channel 126B, and the attachment loop 144 extends outwardly through the narrow channel 126A, allowing the net 120 to be attached to the loop 144. The slidable body 142 can slide within the wide flow path 126B, but is too large to be removed from the flow path 126 through the narrow flow path 126A.

[0086] 7B and 7C show different embodiments of the track 123 and corresponding slidable mounting device 125. More specifically, the track 123 has a substrate 129 that is attachable to the pole 16. Extending from the substrate 129 is a T-shaped rail 131 having a rail body 133 and a cross beam 135 attached to the rail body 133 such that the cross beam 135 forms lips or protrusions 135A, 135B on either side of the cross beam 135.

[0087] Slidably mounted to the track 123 is a slidable mounting device 125 that includes a device body 137, which may be a C-shaped body 137 as shown. More specifically, the body 137 has two arms 139A, 139B with two track wheel pairs 141A, 141B attached to the inner walls of each of the arms 139A, 139B, as best shown in FIG. 7B. The device 125 further has attachment loops 143 coupled at each end to the body 137 via protrusions (or hooks) 145A, 145B extending from the body 137, through which the net portion 120 may be attached, as shown. Apparatus 125 can be mounted to track 123 with wheel 141A positioned on one side of rail 131 (held in place by lip 135A) and wheel 141B positioned on the other side of rail 131 (held in place by lip 135B) so that slidable mounting apparatus 125 slides along rail 131, with wheel 141A contacting and able to roll along lip 135A and wheel 141B contacting and able to roll along lip 135B.

[0088] There are at least two slidable attachment devices (such as devices 140 or devices 125) slidably attached to each corresponding track 122, 123 and the net 120 attached thereto, thereby ensuring that the net 120 is attached to the poles 16 along its length. In some implementations, one attachment device 140, 125 is provided on each foot of the track 122, 123 (resulting in approximately 27 attachment devices 140, 125 for a 30 foot pole 16). Alternatively, any number of devices 140, 125 per pole 16 of any length can be used to slidably attach one side of the net 120 to the poles 16 using 2 to 40 or any other number of attachment devices 140, 125.

[0089] According to a particular embodiment, each attachment loop 143, 144 is a breakable loop 143, 144 that is structurally designed to break (either break or deform) when a predetermined amount of force is applied to the loop 143, 144. In other words, each loop 143, 144 is designed to break when a sufficient external force is applied to the net 120 such that the net 120 is pulled away from the loop 143, 144, thereby not causing any damage to the net 120 or the pole 16 to which it is attached. Thus, any adverse weather conditions that result in damaging forces being applied to the net 120 and the pole 16, such as rain or high winds, are prevented from damaging the net or the pole 16 due to the breakable nature of the loop 143, 144. Each loop 143, 144 can be made of stainless steel wire, as is commercially available and formed using modern technology and processes.

[0090] Alternatively, the mounting tracks 122, 123 and corresponding mounting devices 140, 125 can be any known mounting devices or components that allow for the net 120 to be slidably attached to the poles 16. Additionally, the various mounting track 122, 123 and mounting device 140, 125 embodiments herein can be made from the same materials and via the same processes as the wall sections 14 described above, or can be extruded, as another example.

[0091] For example, in one embodiment, the mounting track 122 may be a t-slot frame available from McMaster-Carr of Elmhurst, Illinois.

[0092] As best shown in FIG. 6B, each pole 16 can also have a pulley 150 associated with each mounting track 122, 123 such that the pulley 150 can be used to raise and lower the net 120 attached thereto. The pulley 150 can be any known pulley 150 for use with such sports equipment. For example, in one particular embodiment, the pulley 150 can be a mounting pulley available from McMaster-Carr of Elmhurst, Illinois. The net 120 can have a rope (not shown) attached to each side thereof, each of which can be threaded through the pulley 150 to use the rope to raise or lower the net 120. In one particular embodiment, the rope is a wet environment rope available from McMaster-Carr of Elmhurst, Illinois.

[0093] Additionally, in some embodiments best shown in FIGS. 8A and 8B, each pole 16 can have at least one mounting bracket 152 attached to two opposing sides of the pole 16. More specifically, the brackets 152 are attached to the side facing the field and spectators (the side not having the mounting track 122) as shown. Each bracket 152 has a through hole 154 formed therein through which any electrical wires or other such items can be placed as needed. Each bracket 152 can be used to mount any accessories or any devices or objects on one or both sides of each pole 16 as desired or needed for the system 10. For example, the types of objects that can be hung on any one or more of the brackets 152 can include, but are not limited to, cameras, speakers, radar guns, TV monitors, ball / strike visual indicators, electrical outlets, phone charging stations, ribbon boards, path egress lighting, and / or emergency lighting or signs.

[0094] In one particular set of examples as shown in FIGS. 13-15, the TV or video board 224 can be mounted in various configurations on the backstop 12 using such brackets 152 (or alternatively using any known mounting device similar to the brackets 152). The video board 224 can be mounted either to the spectator pole 16 (according to one exemplary embodiment, shown in FIG. 14), to the wall 14 (according to another exemplary embodiment, shown in FIG. 13), or to both locations (according to another exemplary embodiment, shown in FIG. 15). According to certain embodiments, the video board 224 can be mounted at various locations along the entire length of the backstop 12. For example, in an embodiment where the backstop 12 is used for a baseball or softball field, the video board 224 can be mounted on both the first substrate side and the third substrate side.

[0095] As shown in Figures 13 and 15, the wall-embedded video board 224 can include many different features. For example, to prevent damage, the video board 224 can be covered with a polycarbonate covering 228 or other damage-preventing covering. This cover 228 can be an additional layer or sheet of material placed over the video board 224. The polycarbonate cover 228 is a clear or transparent material that provides visual access to the video board 224. The cover 228 can have the same or similar dimensions as the video board 224 and can have a thickness of about 0.5 inches. The polycarbonate layer or cover 228 protects the video board 224 from any projectiles that may damage it. Alternatively, any other known protective or additional features can be incorporated into the video board 224.

[0096] According to various implementations, the video boards 224 mounted on the pole 16 can include many different features than those embedded in the wall 14. For example, one or more of these video boards 224 can include up to nine screen panels 226A-226F. The brackets 152 can be attached to the side of the video board 224 that is connected to the pole 16 during installation. Additionally, in some embodiments, the boards 224 mounted on the pole 16 may not have a polycarbonate cover since the boards 224 are not subject to the same risk of projectile damage as boards placed on the wall 14.

[0097] As shown in Figures 9A and 9B, an aspect of the invention includes covering the conduit 86 and any other internal devices at the joint 160 with a two-part covering 160A, 160B, which protects the joint 160 against destruction and adds rigidity to the system 10 when the concrete pad 24 is installed. As can be seen in Figure 9C, the part 160B is bolted or otherwise secured to a portion of the end section 36. Following this, the part 160A is lowered and snapped into abutment with the part 160B (Figure 9A), and then the concrete pad 24 is installed (Figure 9B), where it is poured and leveled directly against the part 160B. Advantageously, the concrete pad 24, when installed, is formed to cover or otherwise overhang at least a portion of the foot 52, which also adds rigidity to the system 10. According to certain embodiments, the two-part covering 160A, 160B can be made of the same materials and through the same processes as the wall section 14 described above.

[0098] In a particular embodiment best shown in Figures 1A and 1D, the backstop 12 can have two corners or angles formed at the junction of the two wall sections 14 (corner junctions 26) to ensure that the backstop 12 conforms to the desired shape of the field (e.g., for baseball and softball field purposes). Alternatively, there may be three, four, five, six, or any number of corners or angled junctions 26 depending on the type of sport / field and / or the desired configuration of the system 10. In a further alternative, there may be no angles or corners.

[0099] As best shown in FIGS. 11A-11D, the corner joint 26 can have a different configuration compared to a non-angle joint (e.g., as shown in FIGS. 4C and 9A-9C and described above). That is, as best shown in FIG. 11A, the inside of the corner joint 26 can have a ball return opening 70 having a ball track 200 for holding a ball inserted into the opening 70. In other words, when a spectator inserts a ball into the opening 70 from the spectator side as described above, the ball passes through the opening 70 on the track 200. In certain embodiments, the track 200 slopes downward from the spectator side to the field side such that the ball rolls toward the field side end of the track 200. In certain embodiments, the track 200 has a blocking structure 202 at the field end of the track 200 to ensure that the ball stops at that point on the track 200. In the particular embodiment shown, the blocking structure 202 is comprised of two tabs 202 that extend upward at the end of the track 200 to stop the progression of the ball on the track 200. Alternatively, any type of structure capable of preventing the ball from rolling over the end of the track 200 can be used as the blocking structure 202 .

[0100] Additionally, as shown in Figures 11B and 11C, the exterior or spectator side of the angled joint 26 can have an angled joint cover 210 attached to the exterior side of the joint 26. The joint cover 210 can be substantially similar in form and function to the covers 160A, 160B described above, except that the corner joint cover 210 is angled to cover the complete corner joint 26 and can have a ball opening 70 defined in the cover 210 as shown. The track 200 described above extends to the ball opening 70 in the cover 210, and the ball can be inserted into the opening 70 and roll along the track 200, as described above.

[0101] In use, various system embodiments disclosed or contemplated herein can be installed in the following manner, as shown in the flow chart of FIG. 10 according to one implementation. First, holes are formed at the site to receive the sleeves 18 (block 182). In some implementations, the holes are formed using a helical drill. The wall sections 14 can then be placed at the desired locations at the site (block 184). According to some implementations, the wall sections 14 can be positioned using a skid loader with slings (known fabric elastic attachment members) or similar construction equipment and associated attachment members. The sleeves 18 are placed in the holes and attached to each wall section 14, such that the desired number of wall sections 14 (for the desired size and configuration of the backstop 12) are coupled to each other via the sleeves 18 (block 186), as exemplarily shown in FIGS. 4A and 4B. More specifically, in certain embodiments disclosed herein, pins (not shown) are inserted through the attachment structures 66 of the wall sections 14 and the attachment structures of the sleeves 18, as described above, thereby coupling the sleeves 18 to the wall 14. Additionally, according to certain embodiments, the sleeves 18 can be attached to the wall sections 14 using pins (not shown) by starting with one particular sleeve 18 along the backstop 12, attaching that sleeve 18 to an adjacent wall section 14, and then gradually moving outward from that sleeve 18 to each adjacent sleeve 18 and performing the same attachment process thereto, adjusting the positioning of each wall section 14 as needed along the way. In this embodiment, once all of the wall sections 14 are attached to their respective sleeves 18, all of the wall sections 14 can be further evaluated to ensure that each section 14 is correctly positioned (including appearing straight, plumb, and level).

[0102] In certain embodiments, each sleeve 18 is inserted into the hole such that about 10 feet of the sleeve 18 is disposed in the ground. Alternatively, the depth of the sleeve 18 in the ground may vary from about 4 feet to about 20 feet. In certain embodiments, each sleeve 18 may be held in place using a temporary mechanism, such as a wedge. Additionally, according to these embodiments, each sleeve 18 may be backfilled. For example, the sleeve 18 may first be backfilled with some gravel and then backfilled with concrete. Alternatively, the sleeve 18 may be backfilled with any material.

[0103] One optional step that can be performed at various points in the installation process (before or after the various steps described herein) is site preparation for installation, i.e., the site can be prepared as needed, including, for example, grading the land at the site, setting datum height pins, marking the ground as needed for placement of components including pole 16, and any other necessary / desirable preparation steps.

[0104] Once the wall section 14 and sleeve 18 are positioned as desired, the pole 16 is inserted into the sleeve 18 (block 188). According to one embodiment, a crane may be used to place the pole 16 into the sleeve 18.

[0105] Once the poles 16 are inserted as described above, they may be positioned and secured in place relative to the sleeves 18 (Block 190). More specifically, in certain embodiments, set screws 110, 112 may be used to position each pole 16 to ensure it is level, and then secured in place using the same screws 110, 112. Even more specifically, any additional backfill or material may be used to fill the aforementioned helical drill holes, and further, a concrete pad 24 may be poured (e.g., on the spectator side of the backstop 12), and turf may be installed (e.g., on the equipment side of the backstop 12) such that the components of the system 10 are juxtaposed and secured (Block 190).

[0106] Once the backstop 12 is permanently embedded as described above, any desired additional components (including flexible conduits) and removable pads as described above can be added (block 192). More specifically, any devices (such as any of a variety of devices that can be attached to the brackets 152 as described above, including cameras, speakers, radar guns, TV monitors, ball / strike visual indicators, outlets, phone charging stations, ribbon boards, path egress lighting, and / or emergency lighting or signs) can be attached to any one or more of the wall sections 14, and / or any wiring can be placed within the walls 14 as needed / desired (e.g., through the conduits 86). Additionally, removable pad sections can be attached to the field side 32 of each wall section 14. Many of the optional equipment and optional wiring can be replaced with other components that can be attached to the structure. Thus, as technology changes or maintenance is required, these equipment and wiring can be easily replaced or updated to accommodate new or different equipment and / or wiring. The padding sections are removable so that such components can be easily accessed without having to modify or remove the concrete or turf components, as well as without having to remove externally attached conduit or wiring.

[0107] In certain optional embodiments, one or more of the optional apparatus or components may be attached to one or more of the poles 16 at any time in the installation process prior to inserting those poles 16 into holes in the ground through the sleeves 18. More specifically, in some embodiments, it is beneficial to attach any such devices / components to one or more of the brackets 152 on the poles 16 while the poles 16 are still resting on the ground or otherwise accessible prior to insertion into the target pole holes.

[0108] Another step that can be performed at various points in the installation is the addition of nets 120. That is, the nets 120 can be attached to mounting tracks 122 on the corresponding poles 16 before the poles 16 are installed, or the nets 120 can be installed after installation.

[0109] The modular nature of the various backstop netting system 10 embodiments herein can provide various advantages for the installation process and the resulting backstop netting 12. More specifically, the modular nature of the system 10 and the predefined dimensions of the various components create significant time-saving and cost-saving efficiencies during installation. For example, the predefined length of the wall sections 14, and therefore the distance between the poles 16, provides the ability to provide the netting 120 with a predefined width that fits between them. Furthermore, the ability to provide various sizes (lengths) of the wall sections similarly provides the ability to have various corresponding net sizes, providing some flexibility when determining which backstop netting 12 size to install without affecting installation efficiency. In addition, the predefined dimensions eliminate the need for any measuring or resizing on-site, thereby allowing all components to be prepared in advance, thus allowing the installer to get the exact pieces (of the specified dimensions) required and know exactly where the pole holes need to be formed on the target site, thereby reducing excess material. Thus, the system 10 embodiments herein provide a systemization of the installation process where as much work as possible is performed at the factory (and less at the installation site).

[0110] Although various embodiments have been described with reference to preferred embodiments, those skilled in the art will recognize that they may be modified in form and detail without departing from the spirit and scope thereof. In other words, the present invention can take many forms and embodiments. The above examples are only a few of them. Since each owner has specific needs and each site has specific characteristics, the sizes of the various components herein, the materials from which the components are made, the power means, the fastening and mounting devices, etc., may vary and not depart from the aspects of the various embodiments herein. To give some sense of some of the options and alternatives, some examples are given below.

[0111] For example, while the poles 16 are shown as being generally square in cross section, this is provided as an exemplary configuration and is not intended to be limiting. Any pole 16 embodiment can be generally circular in cross section or have another cross-sectional configuration.

[0112] Additionally, the size and specific configuration of the wall section 14 may vary from the exemplary embodiment described above. For example, the various openings and internal components of the wall section 14 may be modified based on the needs and modifications of a particular site. Additionally, the dimensions of the wall section 14 may be altered based on the desired overall size and configuration of the backstop 12. Similarly, the associated pole 16 and sleeve 18 and associated components may also vary in size and dimensions accordingly.

[0113] In addition to the exemplary embodiments of the mounting track 122 and mounting device 140 described above, other mounting structures and / or devices can be incorporated to achieve the same functions described above for deploying and retracting the net 120. For example, the mounting track 122 can be formed on the side of the pole 16 rather than being a separate structure attached thereto. Alternatively, the track 122 can have a different configuration than the exemplary configuration described above. Similarly, the mounting device 140 can take any of a variety of configurations of separate components that can be attached to the net 120 and slide along the mounting track 122.

[0114] In certain embodiments, in addition to the exemplary materials mentioned above, the various components herein may be made from any number of different known materials that may be used for similar sports field structures.

[0115] According to some implementations, in addition to any of the specific exemplary processes described above, any known fabrication and processing methods and techniques, such as positive pole oxidation and powder coating any one or more of the components herein for weather resistance, may also be incorporated into various embodiments herein.

[0116] Various exemplary system embodiments disclosed or contemplated herein can be used not only for baseball and softball fields, but also for any other type of sports field or venue, including soccer, American football, etc.

[0117] With respect to the exemplary installation method 180 described above, it is important to note that there may be more, fewer, or different steps, or steps may be performed in a different order, without departing from various aspects of the embodiments herein. For example, in certain alternative embodiments, the sleeve 18 may be inserted into a hole formed in the ground before the wall section 14 is placed in the desired location. Similarly, other aspects of the method may include inserting the pole 16 into the sleeve 18 before positioning or attaching the wall section 14.

[0118] Although the various systems described above are separate implementations, any of the individual components, mechanisms, or devices within the various system embodiments described above, and associated features and functionality, may be incorporated into any of the other system embodiments described herein.

[0119] The terms "about" and "substantially" as used herein refer to variations that may occur (including quantities or structures) with respect to any quantifiable variable, including, but not limited to, mass, volume, time, distance, wavelength, frequency, voltage, current, and electromagnetic fields, for example, through typical measurement techniques and equipment. Furthermore, there are certain inadvertent errors and variations in the real world that may occur due to differences in the manufacture, source, or precision of components used to make various components or to perform methods, etc. The terms "about" and "substantially" also encompass these variations.
