Description

[0001] CROSS-REFERENCE TO RELATED APPLICATIONS

[0002] This application claims the benefit of U.S. Provisional Application No. 63 / 336,566, filed on April 29, 2022, entitled “COMBINATION STOPPER AND BARRIER DEVICE AND RELATED SYSTEMS AND METHODS,” under 35 U.S.C. §119(e), the entire contents of which are hereby incorporated herein by reference. Technical Field

[0003] Various embodiments herein relate to sports field structures, and more particularly to stopper and screen systems for various types of playing fields, including softball and baseball. Background Art

[0004] The installation methods of known motion stop and screen systems are highly customized and site-specific, and therefore very labor-intensive. Typically, large pieces of screen and excess structural components (wood, etc.) are shipped and cut and / or trimmed to size on site during installation. The customized nature of these known systems and methods often results in slow and error-prone installation, which results in imprecise, unprofessional and / or inconsistent stops between sites or venues - in addition to being quite costly.

[0005] Additionally, while some recent stopper systems have fewer poles (to improve sightlines), these systems may have issues with pole integrity (e.g., in the event of wind or weather conditions that depress the block) and have less mounting surface for optional value-added devices (cameras, speed guns, microphones, etc.).

[0006] Furthermore, known stopper and screen systems generally lack modularity and therefore cannot be designed to be modified or adjusted after installation, making any subsequent modifications cumbersome and expensive. Furthermore, such known systems also do not allow the screen to be disassembled or stored, leaving the screen exposed to the elements until damaged - which in turn increases the cost of the system when the screen must be replaced before the end of its useful life.

[0007] There is a need in the art for improved methods and systems for installing and maintaining playing field stoppers and netting systems. Summary of the invention

[0008] Various stopper and screen systems and methods of installing such systems are discussed herein.

[0063] Various embodiments herein relate to a stopper and screen system for various sports fields, including softball and baseball fields. Certain embodiments are modular systems with connectable wall sections and poles and retractable screens, making the system easy to install and modify.

[0064] Figure 1A -E shows an exemplary embodiment of a combined stopper and blocking system 10. As shown, the system 10 has a stopper 12, which is composed of a plurality of modular wall units 14, wherein a plurality of rods 16 are attached to the modular wall units by a plurality of sleeves 18. In the particular system 10, the stopper 12 has eight wall units 14, containing nine rods 16 and nine corresponding sleeves 18. Alternatively, the stopper 12 can have any number of wall units 14, rods 16, and sleeves 18, depending on the desired size. In various embodiments, including the system 10 as shown, the system 10 is installed adjacent to a softball field or baseball field 20, so that the stopper 12 has an angled configuration, wherein the field 20 is disposed on the concave side of the stopper 12 and the viewing or spectator area 22 is disposed on the opposite (or convex) side. Alternatively, due to the modular nature of the system 10 and depending on the type of sports field, the stopper 12 can have any configuration, including a straight (non-angled) configuration.

[0065] According to some aspects, such as Figure 1A , 1C As shown in FIG. 1D , a concrete pad 24 may be added to the spectator side of the stopper 12. The concrete pad 24 may help secure and stabilize the stopper 12 to the field, and also provide a walkway for spectators along the spectator side of the stopper 12. That is, as discussed in further detail below, the spectator side of the stopper may serve as a concrete form on that concrete side as the concrete is poured. Figure 1B The stopper 12 is depicted prior to the addition of the pad 24. Alternatively, no concrete pad is added.

[0066] like Figure 1E As shown (and will be described in further detail below), each sleeve 18 provides both stability and connection for the main components of the stopper 12. More specifically, each sleeve 18 is positioned in the ground, connected to the end of the adjacent wall section 14 and receives the rod 16 in the sleeve 18.

[0067] According to one embodiment, Figure 2A-2C An exemplary wall segment 14 is depicted. 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 segments (or "posts") 36 disposed at each end of the body 30. Figure 2C As shown, the inner side 32 has two large openings 38A, 38B defined in the side 32, which provide access to the inner 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 a top opening (or top slot) 46 defined in the top surface 44 of the body 30. As will be described in further detail below, the slot 46 can be used to receive the screen 120 when the screen is retracted into the cavity 40 of the wall body 30. In addition, as shown in FIG. Figure 2C As shown, each vertical support member 42 has a vertical slot 48 defined therein, and at least one opening 50 defined therein, the vertical slot can receive the screen 120 when it is disposed in the cavity 40, and each opening can receive a conduit (e.g., conduit 86), an electrical wire, etc., as will be described in further detail below. In addition, each wall segment 14 has two support structures (or "feet") 52 attached to a bottom portion of the segment 14. The two feet 52 are positioned near opposite ends of the wall segment 14 so that the feet 52 can be used to ensure that the wall segment 14 can be positioned in an upright position during the installation process, as will be described in further detail below.

[0068] like Figure 2C , 4AAs best shown in 4B and 4B, end posts 36 are attached at or integral with each end of the wall body 30. Each has a vertical axis 60 defined through the post 36, which has openings 62, 64 located at the top and bottom of the post 36, respectively. In certain embodiments, each post 36 has one or more attachment structures 66 that allow the post 36 (and the end of the body 30) to be attached to the attachment sleeve 18 (and thereby to the rod 16), as will be discussed in more detail below, such as by one or more removable pins (not shown). Figure 4B In the particular embodiment shown, the attachment structure 66 is a cylindrical pin receiving structure 66 that extends from the post 36 as shown and mates or aligns with a similar cylindrical pin receiving structure 106 extending from the sleeve 18. Alternatively, any known attachment structure or feature that can be used to attach the end of the wall body 30 to the sleeve 18 may be used.

[0069] In such Figure 4A In some embodiments best shown, each end post 36 may have one or more conduit openings 68 defined on the outside of the post 36. According to certain embodiments, the openings 68 are positioned to allow one or more flexible conduits (or other elongated members discussed elsewhere herein) to pass through the openings 68 so that they can extend out of one end post 36 via the openings 68, around the rod 16, and return to the end post 36 on the other side of the rod 16 via the openings 68. Thus, any number of flexible conduits (as discussed elsewhere herein) can extend around the entire length of the stopper 12 by extending out of each wall segment 14 on the spectator side via the openings 68 and into the adjacent wall segment 14. In the particular exemplary post 36 shown in the figures, there are five conduit openings 68. Alternatively, the post 36 may have one, two, three, four, six, or any other number of openings 68. In further alternatives, the post 36 may have no such openings. In addition, certain embodiments of the end post 36 may include ball return openings 70 defined in the inside and outside of the post 36, such as Figure 4A and 4C This allows a patron or other person to return the ball to the playing field (e.g., in the event that a foul ball goes up and over the system 10 and lands on the spectator side of the stopper 12). In such an embodiment, corresponding openings would be provided in any removable liner sections (e.g., sections 54 discussed elsewhere herein) on the inside of the stopper 12 and in the covers 160A, 160B (as discussed elsewhere herein) on the outside. Alternatively, no such openings are provided.

[0070] Back to Figure 2A and 2BCertain embodiments of the wall segment 14 may include various additional features for enhancing the features of the system 10 and the sports field in which the system 10 is located. For example, the wall segment 14 may have two electrical outlets 80 attached to the outer side 34 of the wall body 30 (e.g., for customers to access to charge their personal devices, etc.). Figure 3A and 3B An exemplary embodiment of the socket 80 is further described. The socket 80 can be arranged in the outer side 34 so that the front of the socket 80 faces the audience side (e.g. Figure 2B ), and the back of the socket 80 extends into the cavity 40 (as shown Figure 2A Each socket 80 may have a removable socket cover 82, such as Figure 2B and 3B Alternatively, the wall section 14 may have one socket, three sockets or any number of sockets.

[0071] In addition, if Figure 2A and 2C As best shown, the cavity 40 may also include a junction box 84 and a conduit 86 attached to the junction box 84 so that any wires attached to the junction box 84 can extend through the conduit 86. The junction box 84 can be used to provide power to any number of various accessories or optional components attached to or otherwise associated with the wall segment 14. As discussed above, the conduit 86 can be positioned through the opening 50 in the vertical support 42 as shown. Alternatively, various insulated wires and / or wiring can be set through the opening 50 and connected to an appropriate one or more boxes 84 without the need for a conduit 86. As shown, the wall 14 has two junction boxes 84. Alternatively, the wall 14 can have one, three, or any number of junction boxes 84, depending on the number of desired accessories or components to be connected to such boxes 84.

[0072] The conduit 86 can be any known conduit, whether flexible or rigid. For example, in one particular embodiment, the conduit 86 can be a medium wall steel conduit (rigid) or an oil resistant, liquid-tight flexible metal conduit (flexible) available from McMaster-Carr, Inc. of Elmhurst, Illinois. In addition, the junction box 84 can be any known enclosure for electronic components. For example, in one particular embodiment, the junction box 84 can be a weatherproof enclosure available from McMaster-Carr, Inc. of Elmhurst, Illinois.

[0073] As mentioned above and as Figure 2CAs best shown in FIG. 1 , according to some embodiments, the field side 32 of each wall segment 14 can have two openings 38A, 38B that provide access to the cavity 40 therein. Alternatively, the field side 32 of the wall segment 14 can have one opening, three openings, or any number of openings to allow access to the cavity 40. These embodiments can have a liner segment 54 removably attached to the field side 32, such as Figure 1C and 1D In the exemplary embodiment shown, there are three removable cushioning sections 54 attached to each wall section 14. Alternatively, the wall sections 14 may have one, two, four, or any number of cushioning sections 54 removably attached thereto. According to some embodiments, as shown in FIG. Figure 2B As best shown in FIG. 1 , the audience side 34 has no such openings or padding. Alternatively, the audience side 34 of the wall 14 may also have one or more openings. In another alternative, the audience side 34 may have one or more removable padding sections that can only be removed from the venue side or otherwise attached in a manner that prevents the audience from removing these sections. In another embodiment, the audience side 34 of the wall 14 may have a decorative facade or surface for signage or advertising.

[0074] The padding section 54 can be any known playground wall padding. For example, in one particular embodiment, the padding section 54 can be a custom stopper padding commercially available from Fieldwallpads.com located in Clarion, Iowa.

[0075] like Fig.12 As best shown in FIG. 1 , according to certain embodiments, each wall segment may also have an adjustable, removable turf attachment structure 220 that is attached to the field side 32 of the wall 14. The turf attachment structure 220 may be any structure that is vertically adjustable on the wall segment 14 and to which field turf placed on the playing field may be attached. In the particular exemplary embodiment 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 embodiment, a commercially available plastic "nail gun" 222 is attached to the L-shaped structure 220 so that turf can be attached to the structure 220 by the nail gun. Alternatively, any adjustable, removable structure that can be used to attach turf to the wall segment may be used.

[0076] Various wall segment 14 embodiments disclosed or contemplated herein may have a length of approximately 24 feet and a height of 3 feet. Alternatively, the length of the wall 14 may range from approximately 12 feet to approximately 24 feet, depending on the desired overall dimensions of the stopper 12. Additionally, the height of the wall 14 may range from approximately 2 feet to approximately 4 feet. The wall segments 14 may be made of, for example, commercial grade steel, aluminum, or some alloy thereof. Additionally, the wall segments 14 may be formed using, for example, state-of-the-art machining, laser cutting, and / or forming techniques and processes. If desired, the parts may be galvanized (e.g., hot-dip), powder coated, or further processed (e.g., for weather resistance). Alternatively, the wall segments 14 may be made of any known material and any known process for use in motion stops and barriers.

[0077] In addition, various rod 16 embodiments disclosed or contemplated herein can have a length of about 30 feet. Alternatively, the length of the rod 16 can range from about 20 feet to about 40 feet, depending on the overall size and height required for the stopper 12. In addition, the width of each rod 16 can be about 6 inches and the depth can be about 6 inches. Alternatively, the width and depth of the rod 16 can be any known amount as needed / desired to change. The rod 16 can be made of, for example, commercial grade steel, aluminum, carbon fiber or some alloys thereof. In addition, the rod 16 can be formed using, for example, the most advanced machining, laser cutting and / or forming techniques and processes. If necessary, the parts can be galvanized (e.g., hot-dip galvanized), powder coated or further processed (e.g., for weather resistance). Alternatively, the rod 16 can be made of any known material and any known process for motion stops and barriers.

[0078] like Figure 4A As shown in FIGS. 4B and 4B , some system 10 embodiments may also have an elongated attachment member (or "sleeve") 18 that couples the two wall segments 14 to the pole 16. In some aspects, the sleeve 18 allows some freedom of movement of the wall segments 14 relative to the pole 16 to which they are attached, thereby providing some adjustability and the ability to modify the positioning of the wall 14 and pole 16 during installation (e.g., if site conditions are not as expected, the ground is uneven, etc.).

[0079] like Figure 1E , 4A4C , the sleeve 18 has an open shaft or elongated cavity (not shown) defined through the length of the sleeve 18, with an opening 102 located at one end (the "top" end) of the sleeve 18 that communicates with the shaft or cavity. Thus, the rod 16 can be inserted through the opening 102 and into the shaft such that the rod 16 is positioned in the sleeve 18 and extends out of the opening 102. According to one embodiment, the elongated cavity (not shown) of the sleeve 18 that can receive the rod 16 extends from the top opening 102 to an internal structure 108 disposed within the cavity of the sleeve 18 that prevents any further advancement of the rod 16 within the sleeve 18. In one particular embodiment, the internal structure 108 is composed of four angle irons 108 (three of which are located at the top of the sleeve 18). Figure 4C 18, which extend from the outer region into the cavity of the sleeve 18 to provide a contact point for the end of the rod 16 within the sleeve 18. Alternatively, the internal structure 108 can be any known structure, such as a lip, a flange, or any other structure or object that is fixed in any appropriate position within the sleeve 18 and prevents the rod 16 from extending further within the sleeve 18.

[0080] Additionally, the sleeve 18 may have two sets of set screws 110, 112 or other adjustable attachment devices that may be used to position and secure the rod 16 in place relative to the sleeve 18. More specifically, as discussed in further detail below, each set screw 110, 112 may be individually adjusted to modify the positioning of the rod 16 to ensure that the rod 16, and therefore the entire stopper 12, is level.

[0081] Additionally, as described above, certain embodiments of the sleeve 18 have one or more attachment structures 106 disposed on opposite sides of the sleeve 18 that allow the sleeve 18 to be attached to the wall segment 14. Figure 4B In the particular embodiment shown, 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 segment 14 that will be attached on each side of the sleeve 18. More specifically, there are four such pin receiving structures 106 (eight total) on each side of the sleeve 18, two upper structures 106 and two lower structures 106. Alternatively, any known attachment structures or features that can be used to attach the ends of the wall body 30 to the sleeve 18 may be used.

[0082] Each sleeve 18 embodiment disclosed or contemplated herein may have a length of about 2 feet. Alternatively, the length of the sleeve 18 may range from about 2 feet to about 12 feet. In addition, the internal dimensions of the shaft defined by the sleeve 18 may have a width of about 7 inches and a depth of about 7 inches. Alternatively, the width and depth range may be from about 4 inches to about 12 inches. In another alternative, the internal dimensions may be any width and depth that allows the rod 16 to pass through it. The various sleeve embodiments 18 herein may be made of the same material and by the same process as the wall segments 14 or rods 16 discussed previously.

[0083] According to some embodiments, the sleeve 18 provides some freedom of movement between the coupled wall segment 14 and rod 16. More specifically, the attachment structure 106 has some limited freedom of movement relative to the wall segment 14 to which it is attached, allowing for some adjustment. In addition, the set screws 110, 112 also allow for some adjustability, in this case, the adjustability of the rod 16 relative to the sleeve 18. Thus, during assembly of the stopper 12, the various components have some freedom of movement, thereby ensuring some amount of adjustability so that the various components are positioned and attached relative to each other in a manner that optimizes the positioning and stability of the entire stopper 12.

[0084] like Figure 5A and 5B As shown, various system 10 embodiments herein include deployable and retractable containment segments 120 that are sized to fit between and attach to poles 16 that are attached to opposite ends of respective wall segments 14. In other words, containment segments 120 are also modular in the same manner as the rest of the system 10 components. Thus, the width of each segment 120 is substantially similar to the length of the respective wall segment 14, such that containment segments 120 extend between and can be attached to opposite poles 16. Additionally, various containment segment 120 embodiments herein can be used in various configurations such as Figure 5A The expanded position shown and Figure 5B The screen section 120 can be moved between the retracted position shown in which the screen section 120 is disposed within the wall section 14 as described above.

[0085] According to some aspects, the barrier 120 can be any known barrier used with a baseball or softball stopper. For example, the barrier 120 can be an Ultra Knotless netting, which is commercially available from Sportsfield Specialties, Inc. of Delhi, New York.

[0086] exist Figure 5AIn one embodiment shown in Figure 7, the barrier net 120 is movably attached to each pole 16 via an attachment track 122 on the pole 16. More specifically, each pole 16 has two attachment tracks 122, one on each side of the pole 16 facing the adjacent pole 16. Alternatively, in some embodiments, the pole 16 intended to be disposed at each end of the stopper 12 may have an attachment track 122 on only one side of the pole 16. Figure 6B 7, the track 122 is comprised of an elongated track body 124 having a channel 126 defined within the track body 124. The channel 126 has a narrow portion 126A defined by a lip 130 on an outer surface 128 of the track body 124 and a wide portion 126B defined within the body 124, which facilitates forming the lip 130 on each side of the narrow channel 126A, as shown in FIG. Fig. 7A Best shown.

[0087] Continue to see Fig. 7A , slidably attached to the track 122 embodiment is a slidable attachment device 140, which can be connected to a portion of the barrier 120 and thereby connect the barrier 120 to the track 122. More specifically, in one embodiment, the slidable attachment device 140 has a slidable body 142, and an attachment ring 144 is attached to the slidable body. The slidable body 142 is sized to fit within the wide portion 126B of the channel 126, but its diameter is greater than the width of the narrow channel 126A. In this way, the slidable attachment device 140 is attached to the track 122 so that the slidable body 142 is slidably disposed within the wide channel 126B, and the connecting ring 144 extends outwardly through the narrow channel 126A so that the barrier 120 can be attached to the ring 144. The slidable body 142 can slide within the wide channel 126B, but is too large to be removed from the channel 126 through the narrow channel 126A.

[0088] Alternatively, Figure 7B and 7C Depicted are various embodiments of a track 123 and corresponding slidable attachment means 125. More specifically, the track 123 has a base 129 that can be attached to the rod 16. Extending from the base 129 is a T-shaped track 131 having a track body 133 and a crossbar 135 attached to the track body 133 such that the crossbar 135 forms a lip or protrusion 135A, 135B on each side of the crossbar 135.

[0089] Slidably attached to the track 123 is a slidable attachment device 125, which includes a device body 137, which can 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 wall of each arm 139A, 139B, as shown in FIG. Figure 7BAs best shown. In addition, as shown, the device 125 has an attachment ring 143 that is coupled to the body 137 at each end by a protrusion (or hook) 145A, 145B extending from the body 137, so that a portion 120 of the barrier net can be attached through the ring 143. The device 125 can be attached to the track 123, wherein the wheel 141A is disposed on one side of the track 131 (and is held in place by the lip 135A) and the wheel 141B is disposed on the other side of the track 131 (and is held in place by the lip 135B), so that the slidable attachment device 125 can slide (or roll) along the track 131, wherein the wheel 141A contacts and can roll along the lip 135A and the wheel 141B contacts and can roll along the lip 135B.

[0090] There are at least two slidable connecting devices (e.g., devices 140 or devices 125) that are slidably attached to each respective track 122, 123 and to the screen 120 attached thereto, thereby ensuring that the screen 120 is attached to the pole 16 along the length of the pole. In some embodiments, one connecting device 140, 125 is provided for each foot of track 122, 123 (thus, there are approximately 27 attachment devices 140, 125 for a 30-foot pole 16). Alternatively, any number of devices 140, 125 may be used for any length of pole 16, such that one side of the screen 120 may be slidably attached to the pole 16 using any number of devices 140, 125 from two to 40, or any other number of attachment devices 140, 125.

[0091] According to certain aspects, each attachment ring 143, 144 is a breakaway ring 143, 144 that is structurally designed to fail (break or deform) when a predetermined amount of force is applied to the ring 143, 144. In other words, each ring 143, 144 is designed to fail when sufficient external force is applied to the fence 120, causing the fence 120 to be pulled away from the ring 143, 144 and thereby avoiding any damage to the fence 120 or the pole 16 to which it is attached. Therefore, any severe weather, such as rain or high winds, that results in destructive forces being applied to the fence 120 and pole 16 is prevented from causing damage to the fence or pole 16 by the breakaway characteristics of the rings 143, 144. Each ring 143, 144 can be made of stainless steel wire, as is commercially available and formed using existing techniques and processes.

[0092] Alternatively, the attachment tracks 122, 123 and corresponding attachment devices 140, 125 may be any known attachment devices or components that allow the barrier net 120 to be slidably attached to the pole 16. Furthermore, the various attachment track 122, 123 and attachment device 140, 125 embodiments herein may be made of the same materials and by the same processes as the wall segments 14 discussed above, or as another example, may be extruded.

[0093] For example, in one embodiment, the attachment rail 122 may be a T-slot bracket commercially available from McMaster-Carr, Inc. of Elmhurst, Illinois.

[0094] like Figure 6B As best shown in FIG. 1 , each bar 16 may also have a pulley 150 associated with each attachment track 122, 123 so that the pulley 150 can be used to raise and lower the barrier 120 attached thereto. The pulley 150 can be any known pulley 150 used with such sporting equipment. For example, in one particular embodiment, the pulley 150 can be a mounting pulley commercially available from McMaster-Carr of Elmhurst, Illinois. The barrier 120 can have a rope (not shown) attached to each side thereof, each rope being threaded through the pulley 150 so that the rope can be used to raise or lower the barrier 120. In one particular embodiment, the rope can be a wet environment rope commercially available from McMaster-Carr of Elmhurst, Illinois.

[0095] In addition, in some aspects, such as Fig. 8A and 8B As best shown, each pole 16 can have at least one attachment bracket 152 attached on two opposing sides of the pole 16. More specifically, the brackets 152 are attached on the side facing the field and spectators as shown (the side without the attachment track 122). Each bracket 152 has a through hole 154 formed in the bracket 152 through which any wires or other such items can be placed as needed. Each bracket 152 can be used to attach any accessories or optional devices or objects on either or both sides of each pole 16 as desired or required by 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, television monitors, ball / strike visual indicators, exits, phone charging stations, tape plates, channel exit lighting, and / or emergency lighting or signage.

[0096] exist Figure 13-15 In the particular set of examples shown, a television or video board 224 can be attached to the stopper 12 in a variety of configurations using such a bracket 152 (or alternatively using any known attachment device similar to the bracket 152). The video board 224 can be mounted in a viewer column 16 (e.g., Fig.14 As shown, according to an exemplary embodiment), the wall 14 (as shown Fig.13 As shown, according to another exemplary embodiment), or the two positions (such as Fig.15According to some embodiments, the video board 224 can be mounted at various locations throughout the length of the stopper 12. For example, in an embodiment where the stopper 12 is used for a baseball or softball field, the video board 224 can be mounted on the first base side and the third base side.

[0097] like Fig.13 and 15 As shown, the video board 224 embedded in the wall can include many different features. For example, to prevent damage, the video board 224 can be coated with a polycarbonate cover 228 or other anti-damage cover. The cover 228 can be an additional layer or piece of material placed on 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 approximately 0.5 inches. The polycarbonate layer or cover 228 protects the video board 224 from any projectiles that might otherwise damage it. Alternatively, any other known protection or additional features can be incorporated into the video board 224.

[0098] According to various embodiments, the video panels 224 attached to the pole 16 may include a number of features that differ from those of the video panels embedded in the wall 14. For example, one or more of these video panels 224 may include up to nine screen panels 226A-226F. The bracket 152 may be attached to the side of the video panel 224 that will be connected to the pole 16 during installation. Furthermore, in some embodiments, the panel 224 attached to the pole 16 may not have a polycarbonate covering because the panel 224 is not subject to the same risk of projectile damage as the panel disposed in the wall 14.

[0099] like Fig. 9A and 9B As shown, aspects of the present invention include covering the conduit 86 and any other internal devices at the joint 160 with a two-part cover 160A, 160B so that when the concrete pad 24 is installed, the joint 160 can prevent damage and increase the rigidity of the system 10. Fig. 9C As can be seen, portion 160B is bolted or otherwise secured to a portion of end section 36. Thereafter, portion 160A may be lowered and snapped into contact with portion 160B ( Fig. 9A ), and then install the concrete pad 24 ( Fig. 9B ); here, cast and leveled directly against portion 160B. Advantageously, concrete pad liner 24 is formed over or otherwise covers at least a portion of foot 52 when installed, which in turn increases the rigidity of system 10. According to certain embodiments, two-part covers 160A, 160B may be made of the same material and by the same process as wall segment 14 discussed previously.

[0100] In certain embodiments, such as Figure 1A and 1D As best shown, the stopper 12 may have two corners or angles (corner joints 26) formed at the junction of the two wall sections 14 to ensure that the stopper 12 conforms to the desired shape of the playing field (e.g., for baseball and softball fields). Alternatively, there may be three, four, five, six, or any number of corners or angled joints 26, depending on the type of sport / field and / or the desired configuration of the system 10. In another alternative, there may be no angles or corners.

[0101] like Fig.11A As best shown in FIG. 11D , the corner joint 26 may have a different configuration than the non-angled joint (e.g., Figure 4C and 9A -9C and as described above). That is, Fig.11A As best shown, the inside of the corner joint 26 may have a ball return opening 70 with a ball track 200 for retaining any ball inserted into the opening 70. In other words, if a spectator inserts a ball into the opening 70 from the spectator side as described above, the ball will pass through the opening 70 on the track 200. In some embodiments, the track 200 slopes downward from the spectator side to the field side so that the ball will roll toward the end of the track 200 that is located on the field side. In some embodiments, the track 200 has a blocking structure 202 at the field end of the track 200 so that the ball must stop at that point on the track 200. In the specific embodiment shown, the blocking structure 202 consists of two tabs 202 extending upward at the end of the track 200 to stop the ball from advancing on the track 200. Alternatively, any type of structure that can prevent the ball from rolling past the end of the track 200 can be used as the blocking structure 202.

[0102] In addition, if Fig. 11B and 11C As shown, the outside or spectator side of the angled joint 26 may have an angled joint cover 210 attached to the outside of the joint 26. The joint cover 210 may be substantially similar in form and function to the covers 160A, 160B discussed above, except that the corner joint cover 210 is angled to cover the entire corner joint 26 and may have a ball opening 70 defined in the cover 210 as shown. The track 200 discussed above extends to the ball opening 70 in the cover 210 so that a ball can be inserted into the opening 70 and roll along the track 200, as described above.

[0103] In use, various system embodiments disclosed or contemplated herein are installed in the following manner, such as according to one embodiment in Fig.10. First, a hole for receiving the sleeve 18 is formed on site (block 182). In some embodiments, an auger is used to form the hole. Then, the wall segment 14 can be positioned at the desired location on site (block 184). According to some embodiments, a skid steer loader or similar construction machine with a sling (known as a fabric elastic attachment member) and associated attachment members can be used to position the wall segment 14. The sleeve 18 can be positioned in the hole and attached to each wall segment 14 so that the desired number of wall segments 14 (the desired size and configuration for the stopper 12) is as shown. Figure 4A and 4B 18 and 19. The sleeves 18 are connected to each other by the sleeves 18 as shown in the exemplary embodiment (block 186). More specifically, in certain embodiments disclosed herein, a pin (not shown) is inserted through the attachment structure 66 of the wall segment 14 and the attachment structure of the sleeve 18 as discussed above, thereby attaching the sleeve 18 to the wall 14. In addition, according to certain embodiments, the pin (not shown) can be used to attach the sleeves 18 to the wall segments 14, by starting at a particular sleeve 18 along the stopper 12, attaching that sleeve 18 to an adjacent wall segment 14, and then gradually moving outward from that sleeve 18 to each adjacent sleeve 18 and performing the same attachment steps thereon, adjusting the positioning of each wall segment 14 along the way as needed. In this embodiment, once all wall segments 14 are attached to their respective sleeves 18, all wall segments 14 can be further evaluated to ensure that each segment 14 is properly positioned (including appearing straight, plumb, and level).

[0104] In some embodiments, each casing 18 is inserted into its hole so that about 10 feet of the casing 18 is located in the ground. Alternatively, the depth of the casing 18 in the ground can vary from about 4 feet to about 20 feet. In some embodiments, a temporary mechanism such as a wedge can be used to hold each casing 18 in place. In addition, according to these embodiments, each casing 18 can be backfilled. For example, the casing 18 can be backfilled with some gravel and then with concrete. Alternatively, the casing 18 can be backfilled with any material.

[0105] One optional step that may be performed at various points in the installation process (before or after the various steps described herein) is to prepare the installation site. That is, the site may be prepared as needed, including, for example, leveling the land at the site, setting reference elevation pins, marking the ground as needed to place components (including poles 16), and any other necessary / desirable preparation steps.

[0106] Once the wall section 14 and sleeve 18 are positioned as desired, the rod 16 may be inserted into the sleeve 18 (block 188). According to one embodiment, the rod 16 may be placed in the sleeve 18 using a crane.

[0107] Once the rods 16 are inserted as described above, the rods 16 can be positioned and secured in place relative to the sleeves 18 (block 190). More specifically, in some embodiments, each rod 16 can be positioned using set screws 110, 112 to ensure it is level and can then be secured in place using the same screws 110, 112. Still more specifically, any additional backfill or material can be used to fill the above-described drilled holes; furthermore, a concrete pad 24 can be poured (e.g., on the spectator side of the stopper 12), and turf can be installed (e.g., on the playing field side of the stopper 12), so that the various components of the system 10 can be juxtaposed and secured (block 190).

[0108] Once the stopper 12 is permanently implanted as described above, any desired additional components (including flexible conduits) and removable pads (box 192) as discussed above can be added. More specifically, any optional devices (such as the various optional devices that can be attached to the bracket 152 as described above, including cameras, speakers, radar guns, television monitors, ball / strike visual indicators, exits, phone charging stations, strip boards, channel exit lighting and / or emergency lighting or signage) can be attached to any one or more wall segments 14 and / or any optional wiring can be positioned within the wall 14 (e.g., via conduits 86) as needed / desired. In addition, removable pad sections can be attached to the field side 32 of each wall segment 14. Many of the optional devices and optional wiring can be interchangeable with other components that can be attached to the structure. Therefore, when technology changes or maintenance is required, these devices and wiring can be easily interchanged or updated to accommodate new or different devices and / or wiring. Because the pad sections are removable, the above components can be easily accessed without modifying or removing any concrete or turf components, and without removing externally mounted conduits or wiring.

[0109] In certain optional embodiments, one or more optional devices or components may be attached to one or more of the poles 16 at any time during the installation process prior to inserting the poles 16 through the sleeves 18 and into the holes in the ground. More specifically, in certain embodiments, it may be beneficial to attach such optional devices / components to one or more brackets 152 on the poles 16 while the poles 16 are still lying on the ground or otherwise accessible prior to insertion into the target pole holes.

[0110] Another step that may be performed at various points in the installation is to add a barrier net 120. That is, the net 120 may be attached to the attachment tracks 122 on the respective poles 16 prior to the poles 16 being installed, or the net 120 may be attached after installation.

[0111] The modular nature of the various stopper and screen system 10 embodiments herein can provide various benefits to the installation process and the resulting stopper 12. More specifically, the modular nature of the system 10 and the predetermined dimensions of the various components provide significant time savings and cost benefits during installation. For example, the predetermined lengths of the wall segments 14 and, therefore, the distances between the rods 16 enable the ability to provide screens 120 of predetermined widths to fit therebetween. Furthermore, the ability to provide wall segments of various sizes (lengths) also enables the ability to have a variety of corresponding screen sizes, thereby providing some flexibility in deciding which stopper 12 size to install without compromising installation efficiency. Furthermore, the predetermined dimensions eliminate the need for any measurements or dimensional modifications to be made in the field, thereby allowing all components to be pre-manufactured and thus enabling the installer to obtain the exact parts (of specific dimensions) needed and know exactly where the rod holes need to be formed on the target site - thereby reducing excess material. Thus, the system 10 embodiments herein result in a systematization of the installation process, wherein as much work as possible is performed in the factory (and as little work as possible at the installation site).

[0112] Although various embodiments have been described with reference to preferred embodiments, those skilled in the art will recognize that changes may be made in form and detail without departing from the spirit and scope thereof. In other words, the present invention may take many forms and embodiments. The foregoing examples are just a few of them. Since each owner may have specific needs and each site has specific characteristics, the dimensions of the various components herein, the materials used for the components, the power devices, the fastening and attachment devices, etc. may vary - and will not depart from the aspects of the various embodiments herein. To understand some of the options and alternatives, several examples are given below.

[0113] For example, the cross-section of the rod 16 is generally square, but this illustration is provided only as an example configuration and is not intended to be limiting. Any embodiment of the rod 16 can be generally circular in cross-section or have other cross-sectional configurations.

[0114] Furthermore, the dimensions and specific configuration of the wall segments 14 may vary from the exemplary embodiments described above. For example, the various openings and internal components of the wall segments 14 may vary based on the needs and variations of a particular site. Furthermore, the dimensions of the wall segments 14 may vary based on the desired overall dimensions and configuration of the stopper 12. Similarly, the dimensions and sizes of the associated rods 16 and sleeves 18 and associated components may also vary accordingly.

[0115] In addition to the exemplary embodiments of the attachment track 122 and the attachment device 140 described above, other attachment structures and / or devices may be combined to achieve the same functions as described above to deploy and retract the barrier net 120. For example, the attachment track 122 may be formed in the side of the rod 16, rather than as a separate structure attached thereto. Alternatively, the track 122 may have a configuration different from the exemplary configuration described above. Similarly, the attachment device 140 may take any of a variety of configurations of separate components that may be attached to the barrier net 120 and slide along the attachment track 122.

[0116] In certain embodiments, in addition to the exemplary materials discussed above, the various components herein may be made from any number of different known materials useful for similar sports field structures.

[0117] According to some embodiments, in addition to any specific exemplary processes discussed above, any known manufacturing and processing methods and techniques, such as anodizing and powder coating any one or more components herein for weather resistance, may also be incorporated into various embodiments herein.

[0118] The various exemplary system embodiments disclosed or contemplated herein may be used not only on baseball and softball fields, but also on any other type of sports field or venue, including soccer, American football, and the like.

[0119] 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 the steps may be performed in a different order without departing from the various aspects of the embodiments herein. For example, in certain alternative embodiments, the sleeve 18 may be inserted into the hole formed in the ground before the wall segment 14 is placed in its desired position. Similarly, other aspects of the method may include inserting the rod 16 into the sleeve 18 before positioning or attaching the wall segment 14.

[0120] Although the various systems described above are separate embodiments, any individual components, mechanisms or devices and related features and functions within the various system embodiments described in detail above may be incorporated into any other system embodiments herein.
