     BACKGROUND 
     Field 
     This disclosure relates to a ball net structure adapted to be used in sports-related activities. More specifically, the disclosure is directed to a customizable ball net structure that is configured to be collapsible to allow for ease of portability, transport and assembly. 
     Description of the Related Art 
     Various sports such as soccer or baseball involve hitting or throwing projectiles such as soccer balls or baseballs toward a desired direction in a field. For practice purposes, it is desirable to capture the ball before it travels a large distance or strikes objects or people. Existing capturing structures include a net attached to the perimeter of a capturing frame and a rigid support frame attached to the capturing frame. The support frame is attached to the capturing frame and provides a base allowing the capturing structure to be disposed on the ground. 
     A disadvantage of such structures is that they cannot be easily collapsed and efficiently stored. This is because both the support frame and the capturing frame must be properly folded and placed in a container. Further use of a capturing frame and a supporting frame makes such structures more expensive to manufacture and harder to carry due to increased weight. 
     There are portable ball net structures available, and they tend to have members that are formed of a single continuous piece or formed from numerous smaller pieces. A disadvantage of nets formed of a single continuous piece is that they cannot be easily collapsed and efficiently stored due in part to its size. For example, a portable soccer goal can be formed of a single continuous frame wherein wheels are attached to a base to allow the soccer goal to be transported or wheeled out to a desired location. Although portable, transporting or positioning the soccer goal can be cumbersome, especially if the soccer goal is a regulation sized goal. 
     Portable goals formed of numerous pieces are more likely to be collapsible and easy transport, but have the distinct disadvantage of being difficult and slow to set up, and not made of robust materials. For instance, loose fasteners may require tools for driving or tightening, and may also become lost in transit or storage or during assembly of the goal on the playing surface. Additionally, collapsible goals or nets may have components that are attached using lockable hinges. The hinges on such goals or nets typically require a locking device to hold the frame of the goal or net in a stable and locked position. Operation of the locking device of a typical hinge normally requires a person to press a button or release/attach a clip to collapse or deploy the goal or net. Pressing the button or releasing/attaching the clip could cause injury to a person, even if performed with care. Furthermore, the locking device can malfunction or break due to repeated strikes from a ball, bat, kicks from users while using the net, and the like. As such, the locking device would be inoperable and would not be able to lock the components at the hinge, such that the hinge would be ineffective at holding the support frame of the goal; thereby rendering the goal inoperable. 
     The above frame structures are typically configured for a single configuration and net, such that the frame is fixed and cannot be configured into a different arrangement for a different net and/or a different sports-related activity. For example, the portable soccer goal formed of a single continuous frame cannot be modified into a differently configured frame for a different net because the single continuous frame is permanently fixed and only designed to be used with a soccer goal net. In addition, frames formed of multiple pieces can only be assembled in the designed single configuration and is not customizable. 
     The disclosure is a ball net structure that is portable, collapsible, and able to be configured into different arrangements for different nets and/or different sports-related activities. For example, the ball net structure is can be configured to receive nets of different sizes and that are designed for different sports-related activities. The ball net structure is further configured to withstand forces applied to the ball net structure in order to improve the stability and/or durability of the ball net structure. The disclosure addresses these needs and provides further related advantages.

     DETAILED DESCRIPTION 
     The disclosure described herein is directed to different aspects of a ball net structure that in some aspects provide a frame structure that is easy to setup and is collapsible such that the frame structure is easy to assemble and disassemble by a single individual, store, is portable, and is customizable for different nets and/or sports-related activities. The detailed description set forth below, in connection with the appended drawings, is intended as a description of various configurations and is not intended to represent the only configurations in which the concepts described herein may be practiced. The detailed description includes specific details for the purpose of providing a thorough understanding of the various concepts. It will be apparent, however, to those skilled in the art that these concepts may be practiced without these specific details. In some instances, well-known structures and components are shown in block diagram form in order to avoid obscuring such concepts. As described herein, the use of the term “and/or” is intended to represent an “inclusive OR”, and the use of the term “or” is intended to represent an “exclusive OR”. 
     The ball net structure can comprise many different materials and can be used in many different applications such as, but not limited to, practicing soccer skills, throwing and/or hitting baseballs. The ball net structure according to the disclosure can be arranged in many different ways with many different components, and is generally arranged to provide a net structure to capture or catch a projectile. In one aspect, as broadly described herein, a ball net structure comprises a base structure comprising at least one support portion and at least one base extension. The ball net structure further comprises a hinge, wherein the at least one support portion is coupled to the at least one base extension and the hinge. At least one rod is removably coupled to the base structure and is adapted to be received by a net. The net is adapted to exert a pulling force on the at least one rod causing the at least one rod to exert a torque force onto said hinge, whereby the at least one support portion is locked into place. In other aspects, the ball net structure comprises a base structure comprising a first support portion and a second support portion, wherein the first and second support portions are coupled to a hinge, such that the first and second support portions are opposite each other and the hinge is interposed therebetween. At least one rod is removably received by the base structure, wherein a net is adapted to receive the at least one rod. The ball net structure further comprises a first base extension coupled to the first support portion and a second base extension coupled to the second support portion. The first and second base extensions are adapted to further support the load of the ball net structure and allow the ball net structure to remain upright while in use. In some aspects, the ball net structure can also comprise an attachment device proximate the base structure, such that the attachment device is adapted to receive an attachment cord that is adapted to receive a weighted device or force resistance device to provide additional structural support. The attachment device can also be configured to receive part of the net. In some aspects, the attachment device can be on at least one base extension, at least one support portion, the hinge, or a combination thereof. At least one advantage of the ball net structure is that the ball net structure is configured to exert a force on the hinge so as to maintain the ball net structure in an upright state when deployed. This arrangement allows the hinge to remain in a fixed state without the need of one or more locking devices to lock the support portion to the hinge. 
     In another aspect of the disclosure, a ball net structure comprises a base structure comprising a first support portion, a first base extension, and a first base extension hinge, wherein the first support portion and the first base extension are coupled to the first base extension hinge. The base structure further comprising a second support portion, a second base extension, and a second base extension hinge, wherein the second support portion and the second base extension are coupled to the second base extension hinge. The first base extension is configured to engage an internal locking mechanism within the first base extension hinge in order to lock the first base extension within the first base extension hinge when the first base extension is fully deployed in an open position. The first base extension is further configured to engage another internal locking mechanism within the first base extension hinge in order to lock the first base extension within the first base extension hinge when the first base extension is retracted in a closed position. The first support portion and the second support portion are pivotally coupled to a base hinge of the base structure, such that the first support portion and the second support portion are opposite each other. At least one rod is removably coupled to the base structure and is received by a net. The net is adapted to exert a pulling force on the at least one rod such that the at least one rod is in a flexed state. The at least one rod configured to exert a torque force onto the base hinge in order to lock the first and second support portions. 
     In another aspect, a ball net support structure comprises a support portion comprising a first end and a second end, a first base extension hinge coupled to the first end of the support portion, a first base extension leg coupled to the first base extension hinge such that the first base extension leg pivots about a first pivot point at a first position of the first base extension hinge. The first base extension leg can be configured to engage a locking mechanism at a second position of the first base extension hinge. The ball net support structure can further comprise a second base extension hinge coupled to the second end of the support portion, a second base extension leg coupled to the second base extension hinge, such that the second base extension leg pivots about a second pivot point at a third position of the second base extension hinge. The second base extension leg can be configured to engage a locking mechanism at a fourth position of the second base extension hinge. The ball net support structure further comprising a plurality of rods removably coupled to the ball net support structure and configured to receive a net. 
     The ball net structure of the disclosure can provide a number of additional advantages beyond those mentioned above. For example, the hinge allows for ease of assembly/disassembly and storage of the ball net structure because the hinge does not have a locking device that needs to be forcibly engaged and/or disengaged. Typical hinges have a locking pin that prevents an element from pivoting about a hinge. These locking pins can be hard to engage and/or disengage which could cause injury to the person trying to engage and/or disengage the locking pin. Other typical hinges have a locking button, instead of a locking pin, that is depressed in order to allow an element to be engaged and/or disengaged from the hinge. In such hinges, operation of the locking button requires the person to press down and pivot the element about the hinge. In some instances, the person pressing the locking button could get a portion of their finger caught and/or pinched by the button causing injury. In addition, these locking buttons/pins may not withstand forces imparted by a ball, projectile, bat, and/or forces from users, such as kicks, that occur during use. Another advantage of the disclosure is that the ball net structure is collapsible such that the ball net structure can be folded upon itself and form a smaller package that can easily be transported and/or stored without taking up too much physical space. A disadvantage of typical hinges having the locking pin or the locking button is that the locking pin or the locking button will deteriorate over time due to many different factors, such as the load imparted onto them or by damage due to repeated use or misuse. At least another advantage of the disclosure is that the base extension hinge is configured to withstand the forces imparted by a ball, projectile, bat, and/or forces from users, such as kicks, that occur during use and/or while disassembled and stored, in order to improve the durability and/or stability of the ball net structure. 
     The ball net structure of the disclosure can be used to stop or capture a ball or the like when performing sports-related activities. However, the disclosure is not intended to be limited to such aspects. As further described below, the ball net structure can be arranged to allow an individual to easily deploy and disassemble the ball net structure in an outdoor or indoor setting. In addition, the ball net structure can be used as a barrier or safety net to protect spectators and/or other people that may be on a practice field. 
     The disclosure is described herein with reference to certain aspects, but it is understood that the disclosure can be embodied in many different forms and should not be construed as limited to the aspects set forth herein. In particular, the disclosure is described below in regards to a ball net structure to practice or perform sports-related activities in an outdoor setting, but it is understood that the disclosure can be used for many other applications in many different settings. The components of the ball net structure can have different shapes and sizes beyond those shown in the figures or discussed herein. 
     Although the terms first, second, etc. may be used herein to describe various elements or components, these elements or components should not be limited by these terms. These terms are only used to distinguish one element or component from another. Thus, a first element discussed herein could be termed a second element without departing from the teachings of the present application. It is understood that actual systems or fixtures embodying the disclosure can be arranged in many different ways with many more features and elements beyond what is shown in the figures. 
     It is to be understood that when an element or component is referred to as being “on” another element or component, it can be directly on the other element or intervening elements may also be present. Furthermore, relative terms such as “between”, “within”, “below”, and similar terms, may be used herein to describe a relationship of one element or component to another. It is understood that these terms are intended to encompass different orientations of the device in addition to the orientation depicted in the figures. 
     Aspects of the disclosure are described herein with reference to illustrations that are schematic illustrations. As such, the actual thickness of elements can be different, and variations from the shapes of the illustrations as a result, for example, of manufacturing techniques and/or tolerances are expected. Thus, the elements illustrated in the figures are schematic in nature and their shapes are not intended to illustrate the precise shape of a region of a device and are not intended to limit the scope of the disclosure. 
       FIGS. 1-2   c  show one aspect of a ball net structure  10  according to an aspect of the disclosure. In some aspects, the ball net structure  10  is configured such that the ball net structure  10  can be deployed in an outdoor setting such as, but not limited to, a natural grass, synthetic field, dirt, concrete or the like. In other aspects, the ball net structure  10  can be deployed in an indoor setting such as but not limited to an indoor training facility, residential or commercial setting having a synthetic or natural surface, or the like. The ball net structure  10  can then be used in sports-related activities, such as but not limited to baseball, softball, soccer, football and the like. The ball net structure  10  can also be used to allow users to practice kicking, hitting or throwing a ball or other projectile to the ball net structure  10 , such that the ball net structure captures or catches the ball so that the user does not have to travel great distances to retrieve the ball. The ball net structure  10  comprises a base structure  12  including first and second support portions  14 ,  16  pivotally attached to a hinge  22 , a plurality of rods  26  removably coupled to the base structure  12 , and a net  30  adapted to receive the plurality of rods  26 . The aspect shown in  FIG. 1  has two rods  26 , but other aspects can have more than two rods  26 . The rods  26  are configured to exert a force on the hinge  22  in order to lock the first and second support portions  14 ,  16  in place and prevent rotation of the first and second portions  14 ,  16  about the hinge  22 . The base structure  12 , rods  26  and net  30 , when fully assembled and deployed, are adapted to withstand the force of a ball or projectile so as to capture the ball while keeping the ball net structure  10  in an upright position. 
     For the same or similar elements or features, the reference numbers from  FIGS. 1-2   c  will be used throughout the application herein. In one aspect of the disclosure, the base structure  12  can further comprise a first base extension  18  coupled to the first support portion  14  and a second base extension  20  coupled to the second support portion  16 . This arrangement allows the first and second base extensions  18 ,  20  to provide additional structural support to further stabilize the ball net structure  10  in an upright position. In some aspects, the first and second base extensions  18 ,  20  can be coupled to the respective support portions  14 ,  16  such that the first and second base extensions  18 ,  20  are perpendicular to the respective support portion  14 ,  16 . In other aspects, the first and second base extensions  18 ,  20  can be angled in a V-shaped configuration and configured to raise the base structure  12  above the ground or surface or allow the base structure  12  to contact the ground or surface, wherein the angle of the V-shaped base extensions  18 ,  20  can be in the range of 90°-140° (degrees). In yet other aspects, as in  FIG. 3 , a base extension  55  comprises a base extension hinge  50  coupled to the support portions  16  and  14  (not shown), first and second base extension legs  52 ,  54  pivotally attached to the base extension hinge  50  about a respective pivot point  51 , and can be locked into place by respective locking pins/buttons  53 . In this arrangement, the legs  52 ,  54  can be released from their respective locking pins/buttons  53  and are able to rotate about pivot points  51  towards the support portions  16  and  14  such that the base structure  56  is further collapsible and easy to transport. In the aspect of  FIG. 1 , the base extensions  18 ,  20  are stationary and are not able to be rotated towards their respective support portion  14 ,  16 . Additionally, the first and second legs  52 ,  54 , in  FIG. 3 , are arranged, either bent, curved, or straight, such that the base structure  56  is elevated off the ground or surface. However, in other aspects, the legs  52 ,  54  can be arranged to allow the base structure  56  to contact the ground or surface. The legs  52 ,  54  can also comprise the attachment device  35 , attachment cord  32  and ring  34  as discussed in the aspect of  FIG. 1 . 
     The first and second support portions  14 ,  16  each have a first end  15  and a second end  17 , wherein the first end  15  of each of the support portions  14 ,  16  is coupled to the respective base extensions  18 ,  20 . The first and second support portions  14 ,  16  extend from the respective base extensions  18 ,  20  towards a hinge  22  and are pivotally coupled to the hinge  22 , such that the base extensions  18 ,  20  are opposite the hinge  22 . The second ends  17  of support portions  14 ,  16  are coupled to the hinge  22  using hinge pins  24 . The hinge  22  has openings  25  that receive the hinge pins  24  so as to couple the support portions  14 ,  16  to the hinge  22 . In one aspect, the hinge pins  24  can be screws with a nut to hold the screw in place. However, in other aspects, the openings  25  of the hinge  22  can be threaded to receive the hinge pins  24 , or the hinge pins can be nails, rivets or the like. The support portions  14 ,  16  can be coupled to the hinge  22  using various known means in the art and is not intended to be limited to the aspects disclosed herein. The first and second support portions  14 ,  16  can be made of many different materials, such as but not limited to wood, plastic, metal, a composition thereof or the like. The first and second support portions  14 ,  16  can be formed to have many different shapes, such as but not limited to circular, square, polygonal, a combination thereof or the like. The first and second portions  14 ,  16  of the aspect of  FIGS. 1-2   c  are shown as having a square-like shape. 
     The hinge  22  is arranged to receive at least a portion of the first and second support portions  14 ,  16  such that the support portions  14 ,  16  are able to rotate about the respective hinge pin  24 . In one aspect, the hinge  22  is configured to be a U-shaped channel having a hinge base  27 , sidewalls  29  and openings  25  to allow respective hinge pins  24  to be received by the hinge  22  as well as the first and second support portions  14 ,  16 , such that the first and second support portions  14 ,  16  are pivotally coupled to hinge  22 . In the aspect of  FIG. 1 , the second ends  17  of each of the first and second support portions  14 ,  16  are pivotally coupled to the hinge  22 . However, in other aspects, the first and second support portions  14 ,  16  can be pivotally coupled to the hinge  22  at different locations between the first and second ends  15 ,  17 . 
     An advantage of the disclosure is that in some aspects the hinge  22  can be U-shaped which allows the hinge  22  to hold the first and second support portions  14 ,  16  in a stable and parallel position along the same axis and also provides a physical stop which prevents the first and second support portions  14 ,  16  from pivoting beyond the physical stop. However, in other aspects, the hinge  22  can be shaped in different forms such that the support portions  14 ,  16  are not aligned along the same axis, can be parallel or non-parallel, yet still provide a physical stop to prevent the portions  14 ,  16  from rotating beyond the physical stop. 
     As shown in  FIGS. 1-2   c , the first and second portions  14 ,  16  are coupled to the hinge  22 , using hinge pins  24 , such that they rotate about the respective hinge pin  24 . Rotation of the first support portion  14 , in a direction opposite the second support portion  16 , about the hinge pin  24  will stop when the first support portion  14  comes into contact with the hinge base  27  of the hinge  22 ;  FIG. 2 c    shows an example of the support portions  14 ,  16  in contact with the hinge base  27  and precluding further rotation. The hinge base  27  provides a physical stop and prevents the first support portion  14  from further rotation. The second support portion  16  is similarly configured as the first support portion  14  and will stop rotating about hinge pin  24  when the second support portion  16  contacts the hinge base  27 . The physical stop provided by the hinge  22  properly aligns the first and second support portions  14 ,  16  when assembling the ball net structure  10 . Yet another advantage of the disclosure is that the hinge  22  allows the base structure  12  to be folded onto itself so that the ball net structure  10  can be easily stored as well as easy to transport. This arrangement allows the base structure  12  to reduce its size and/or area, thereby allowing the ball net structure  10  to be stored in a small container. 
     When assembling the ball net structure  10 , the first and second support portions  14 ,  16  of the base structure  12  are rotated away from the opposite support portion  16 ,  14  towards the hinge base  27 . When the support portions  14 ,  16  are in contact with the hinge base  27 , precluding further rotation, the base structure  12  is ready to be placed on the playing surface, such as but not limited to a natural grass, synthetic filed, cement, wood, asphalt, or the like. The base structure  12  is placed on the playing surface such that the hinge base  27  is opposite the playing surface. In other words, the hinge base  27  does not contact the surface upon which the base structure  12  is positioned on. At this point, the at least one rod  26  is ready to be installed. 
     The base structure  12  is further adapted to receive the at least one rod  26 . In one aspect, the base structure  12  comprises at least one shaft  31  extending substantially vertically and configured to receive one of the at least one rod  26 . In another aspect, the base structure  12  comprises a plurality of shafts  31 , wherein each respective shaft  31  is adapted to receive a respective one of the at least one rod  26 . In the aspect of  FIG. 1 , the base structure  12  comprises two shafts  31 , with one shaft  31  coupled to the first base extension  18  and another shaft  31  coupled to the second base extension  20 . As shown in  FIG. 1 , each of the shafts  31  are coupled to a respective base extension  18 ,  20  proximate the first end  15  of the first and second support portions  14 ,  16 . However, in other aspects, the shaft  31  can be positioned at various other locations on the base extensions  18 ,  20  and/or the support portions  14 ,  16 , or a combination thereof. In yet other aspects, the base structure  12  can comprise more than two shafts  31  for aspects that comprise more than two rods  26 . The number of shafts  31  present will be equal to the number of rods  26 . 
     The at least one rods  26  are configured to be securely held within the shaft  31 , such that the shaft  31  maintains a stable structural connection between the shaft  31  and the at least one rods  26  and prevents the rod  26  from being removed from the shaft  31  when the ball net structure  10  is assembled. In one aspect of the disclosure, the shaft  31  is similarly shaped as the rod  26 , such as but not limited to cylindrically shaped, and is slightly larger than the rod  26  such that the rod  26  can easily be received by the shaft  31 . The shaft  31  can further comprise a sheath contacting the inner wall of the shaft  31  that receives the rod  26 . The sheath is adapted to protect the rod  26  within the shaft  31  from forces exerted on the rod  26  when the ball net structure  10  is fully assembled. As will be discussed below, upon assembly of the ball net structure  10 , the rods  26  experience a moment force at the point where the rod  26  is received by the shaft  31 , and causes the rod  26  to exert a compression force upon the sheath. The sheath thereby protects the rod  26  from the forces exerted on and/or by the rod  26 . 
     In other aspects, the shaft  31  can be shaped such that the radius of the shaft  31  decreases the further the rod  26  is inserted into the shaft  31 . In this arrangement, the shaft  31  uses a compression force to form the structural connection between the shaft  31  and the rod  26 . In other aspects, mechanical devices, such as but not limited to, screws, nuts, nails, rivets or the like, can be used to form the structural connection so as to securely attach the rod  26  to the shaft  31 . In yet other aspects, the rods  26  can be configured to have an attachment means such that the rods  26  can be attached to the shaft  31 ; non-limiting examples of such attachment means are the rods  26  being threaded and screwed into the shaft  31  or the rod  26  and shaft  31  configured similarly like a bayonet-type locking device. 
     In the aspect of  FIG. 1 , the rods  26  are circularly shaped and the shaft  31  is also correspondingly circularly shaped to receive the rod  26 . The shape of the rod  26  and shaft  31  is not intended to be limited to a circular shape, other shapes such as quadrilateral, triangular, or any other polygonal shape can be used. The shaft  31  can also be similarly shaped as the rod  26 , but in some aspects, the shaft  31  can be shaped differently than the rod  26 . The rods  26  can be made of many different materials known in the art, such as but not limited to fiberglass or carbon fiber, such that the rods  26  are flexible, elastic, capable of returning to an initial form or state after deformation, and able to withstand the impact forces applied by sports-related balls and/or other projectiles that can be captured or caught by the ball net structure  10 , or thrown, kicked, and/or hit towards the ball net structure  10 . 
     The rods  26 , when received by the shaft  31  flare outwards in a direction opposite the hinge  22 , such that the rods  26  are in a relaxed state and are substantially straight. A net  30  comprising at least one sleeve  33  is arranged to receive the at least one rod  26  and is adapted to exert a force on the at least one rod  26  bending the at least one rod  26  into a flexed state. Inserting the at least one rod  26  into the sleeve  33  requires that the at least one rod  26  be bent from the relaxed state into a flexed state to allow the sleeve  33  to receive the at least one rod  26 . As shown in the aspect of the disclosure in  FIG. 1 , when both rods  26  are received by the respective shaft  31  and the net  30 , both rods  26  are bent in a direction towards the hinge  22  and into the flexed state. Removal of the net  30  allows the rods  26  to return to their original form of the relaxed state. Repeated use of the ball net structure  10  does not result in the rods  26  being permanently bent in a shape similar to that of the flexed state. The net  30  can be easily installed and removed by a single individual. 
     The net  30  imparts a pulling force on each of the rods  26  which causes each of the rods  26  to bend in a direction towards the hinge  22 . Once bent towards the hinge  22 , the rods  26  are in the flexed state and experience a moment force about its pivot point. The pivot point of each of the rods  26  corresponds to the point at which the rods  26  are received by the shaft  31 . The moment force experienced by the rods  26  is imparted onto the hinge  22  and the first and second support portions  14 ,  16  of the base structure  12 , with the transferred force being greatest at the hinge  22 . This transferred force further assists in locking the hinge  22  and base structure  12 , such that the first and second support portions  14 ,  16  are locked into place. 
     An advantage of the disclosure is that the force exerted onto the rods  26  by the net  30  results in a torque force experienced by the rods  26  and transferred to the hinge  22 , which allows the hinge  22  to lock the first and second support portions  14 ,  16  into place without the need of a locking device such as a locking clip or button. The absence of such a locking device on the hinge  22  prolongs the lifetime of the ball net structure  10  due, in part, to the hinge  22  not deteriorating or breaking down due to failure or malfunctioning of the locking clip or button. 
     The net  30  can be a mesh surface or any typical net known in the art. The net comprises at least one sleeve  33  adapted to receive the rod  26  so at to mount the net  30  onto the rods  26 . The aspect of  FIG. 1  shows the net  30  having a sleeve  33  in the form of a plurality of loops that receive the rods  26 . However, in other aspects, such as  FIG. 4 , the net  30  comprises a plurality of sleeves  33  wherein at least one of the plurality of sleeves  33  receives the base structure  12 , in order to provide additional structural support for the ball net structure  10 . The sleeve  33  can be configured in many different ways, such as but not limited to a sleeve that spans the length of the rod, a plurality of smaller sleeves that are spaced apart from each other and run along the length of the rods  26 , or a sleeve that spans along a partial length of the rods  26 . In some aspects, each rod  26  comprises an endcap  28  opposite the portion of the rod  26  that is received by the shaft  31  and is configured to receive at least a portion of the sleeve  33 , such that the endcap  28  prevents the sleeve  33  from coming off the rods  26  while the ball net structure  10  is assembled and/or in use. In one aspect, the endcaps  28  can have a tab that extends outward beyond the external shape of the rod  26  that prevents the net  30  from coming off the rod  26 . However, in other aspects, the endcaps  28  can have other means of preventing the net  30  from coming off the rod  26 , such as but not limited to a hook, loop, locking clip, or the like. 
     The ball net structure  10  according to the disclosure is designed to withstand the force of a ball or other projectile so as to catch or capture the ball, such that the ball net structure  10  maintains an upright standing position. In some aspects of the disclosure, the ball net structure  10  can comprise at least one attachment device  35  that can receive an attachment cord  32  having a ring  34 . The attachment cord  32  allows for the connection of a weight, stake or similar device to provide additional support for the ball net structure  10 . In the aspect of  FIG. 1 , the attachment device  35  is a loop-like device that is coupled to the base structure  10  and allows the attachment cord  32  to be tied or coupled to the attachment device  35 . The attachment cord  32  can be a bungee cord, rope, or the like. The ring  34  allows for a weighted or force-resistant device (not shown), such as but not limited to a sandbag or a suction cup, to be attached to the base structure  12  to provide additional support for the ball net structure  10  and prevent the ball net structure  10  from moving, falling over, or shifting. The ring  34  can also be used to receive a stake, staple, hook or similar device that is inserted into the ground or surface so as to attach the ball net structure  10  to the ground or surface. 
     The attachment device  35  is configured to extend laterally or horizontally from the base structure  12 , such that the weight or similar device attached to the cord  32  provides a lateral support, which prevents the ball net structure  10  from lifting upwards or shifting its position. In some aspects, the net  30  can be received by the attachment device  35 , such that the sleeve  33  of the net  30  is coupled to the attachment device  35 . The attachment device  35  allows for both the sleeve  33  and the cord  32  to be coupled to the attachment device  35 . An advantage of this arrangement is that the weight or similar device attached to the attachment device  35  can also act as a shock absorber when a ball or projectile is caught or captured by the ball net structure  10 . The force of the ball is distributed throughout the ball net structure  10  and also partially transferred to the weight or device attached to the attachment device  35 , which further provides additional support to the ball net structure  10  which increases the stability and/or the force the ball net structure  10  can withstand. In other aspects of the disclosure, the ball net structure  10  comprises a plurality of attachment devices  35  and can be disposed on the base structure  12  and/or on base extensions  18 ,  20 .

To collapse the first base extension  106 , the first base extension  106  is pivoted towards the first support portion  104  such that the first base extension is adjacent the first support portion. To deploy the first base extension, the first base extension is pivoted within the first base extension hinge away from the first support portion until the first base extension reaches the end of the pivot range, at which point the first base extension  106  can engage the internal locking mechanism within the first base extension hinge  108  to lock the first base extension. The first base extension  106  engages the internal locking mechanism by slidably inserting the first base extension into the first base extension hinge  108 . The second base extension  118  is pivoted with respect to the second support portion  116  to deploy and/or collapse the second base extension  118  similarly as the first base extension  106 . As such, when the second base extension is collapsed, the second base extension is adjacent the second support portion. When deployed, the second base extension is pivoted within the second base extension hinge  120  away from the second support portion  116  until the second base extension reaches an end of a pivot range. The second base extension  118  is thereby positioned to engage the internal locking mechanism within the second base extension hinge  120 , wherein the second base extension is inserted into the second base extension hinge  120  and engages the internal locking mechanism within the second base extension hinge  120  to lock the second base extension. 
     The base structure  102  is configured to receive at least one flexible rod  112 . In the aspect of  FIG. 6 , the base structure  102  receives a plurality of flexible rods  112 , wherein each flexible rod  112  comprises an upper end  502  and a lower end  504 , such that the lower end  504  is removably coupled to the base structure  102 . A first flexible rod  112  is received by the first base extension hinge  108 , a second flexible rod  112  is received by the second base extension hinge  120 , a third flexible rod  112  is received by the first base extension  106 , and a fourth flexible rod  112  is received by the second base extension  118 .

A second base extension bracket  200  can be on an end  618  of the second base extension  118  opposite the second base extension hinge  120 . In some aspects, the base extension bracket  200  can be anywhere on the base extension between the end and the base extension hinge, and is not intended to be limited to being on the end of the base extension. The base extension bracket  200  is configured to receive at least one rod  112 . As shown in  FIG. 6 , the third rod  112  is received by the base extension bracket  200  on the end  616  of the first base extension  106 , and the fourth rod  112  is received by the base extension bracket  200  on the end  618  of the second base extension  118 . The flexible rods  112 , as shown in  FIG. 6 , are in the relaxed state and are substantially straight. The rods  112  in the relaxed state flare outwards in a direction away from the base structure  102 . A net  114  is arranged to be received by the first and second base extensions  106 ,  118 , the support portion  602 , and at least the upper end  502  of the at least one flexible rod  112 . The net  114  is adapted to exert a force on the at least one flexible rod bending the at least one flexible rod into a flexed state, such that a net tension pulls the at least one flexible rod into the flexed state. In the aspects of  FIGS. 5 and 6 , the ball net structure  100  comprises four rods  112 , and each of the four rods  112  is received by the net  114  such that the rods  112  are bent in a direction towards the base structure  102  and into the flexed state. However, the disclosure is not intended to be limited to the aspects disclosed herein. In some aspects, the ball net structure can comprise less than four rods, more than four rods, or any number of rods and is not intended to be limited to four rods. At least the upper end  502  of the flexible rods  112  are configured to receive the net  114 , such that the net bends the rods from a relaxed linear state to an arcuate state or a bow shaped flexed state, such that the rods are biased away from at least one rod to hold the net upright. The net tension pulls at least the first rod into the arcuate state and the net tension simultaneously pulls the remaining rods into the arcuate state. The support portion  602  and the first and second base extensions  106 ,  118  support the load of the ball net structure  100  and allow it to remain upright on a surface. The first and second base extensions absorb at least part of a load exerted onto the ball net structure  100  from a ball or other projection when in use to stabilize the ball net structure on a surface. 
       FIGS. 7-15  show one aspect of a base extension hinge according to the disclosure. 
     The first base extension hinge  108  comprises at least one groove  302 , a pivot  304 , and a shaft  340  configured to receive a flexible rod  112 , wherein part of the first base extension  106  is received by the first base extension hinge  108  and within the at least one groove  302 , such that the first base extension  106  can pivot about the pivot  304  within the at least one groove  302 . The base extension hinge  108  comprises at least one groove sidewall  306 , a groove base  308 , and a groove top  310 , wherein the at least one groove sidewall  306  at least partially defines the range of which the first base extension  106  can pivot within the at least one groove  302 . The first base extension hinge  108  further comprises a stop  312  within the at least one groove  302 , wherein the stop  312  assists in preventing substantial movement of the first base extension  106  within the at least one groove  302 . In some aspects, the stop  312  assists in maintaining the position of the first base extension  106  at the ends of the range of pivot motion within the groove  302 , such that the first base extension  106  is secured and does not freely move. In some aspects, the range of pivot motion can comprise an opened end  314  wherein the first base extension  106  is deployed, as shown in  FIG. 7 , and a closed end  316  wherein the first base extension  106  is retracted or collapsed and proximate the first support portion  104 , as shown in  FIG. 8 . The stop  312  provides an obstacle to maintain the positioning of the first base extension  106  at either the opened end  314  or the closed end  316 . The stop  312  can be shaped to partially correspond to part of the first base extension  106  received within the groove  302 . In some aspects, the stop  312  comprises a first edge  313  that is proximate the first base extension  106  when positioned at the opened end  314 . In some aspects, the stop  312  can comprise a second edge  315  that is proximate the first base extension  106  when positioned at the closed end  316 . The stop  312  is an elevated or raised structure with respect to the groove base  308  such that the first and second edges  313 ,  315  provide a physical barrier that assists to maintain the first base extension  106  at either the opened end  314  or the closed end  316 . The stop  312  prevents the first base extension  106  from freely moving within the groove  302 , and thereby assists in stabilizing the base structure  102 . In some aspects, the first and second edges  313 ,  315  extend from the groove base  308  to the same height. While in other aspects, the first and second edges  313 ,  315  extend from the groove base  308  to different heights. In some aspects, at least part of the first and second edges  313 ,  315  can contact part of the first base extension  106  to maintain the position of the first base extension  106 . The stop  312  provides some resistance to prevent slight movement of the first base extension  106 , but does not prevent the first base extension  106  from moving between the opened end  314  and the closed end  316 . The stop  312  can be configured in many different ways and is not intended to be limited to the aspects disclosed herein. In the aspect of FIGS.  7  and  8 , the groove  302  comprises one stop  312  on the groove base  308 . However, in other aspects, the groove  302  can comprise one or more stops  312  on the groove base  308 . In some aspects, the one or more stops  312  can be on the at least one groove sidewall  306 , the groove base  308 , the groove top  310 , and/or a combination thereof. In some aspects, a first stop  312  can be on the groove base  308  and a second stop  312  can be on the groove top  310 , such that the first and second stops are opposite each other and substantially aligned. 
     When the first and second base extensions  106 ,  118  are positioned at their respective closed end  316  of the groove  302 , the base structure  102  is in a closed state and in condition to be stored for later use. When the first and second base extensions are positioned at their respective opened end  314  of the groove  302 , the base structure  102  is in a deployed condition and ready to be used. The range of pivot motion of the first and second base extensions is not intended to be limited to the aspects described herein. For example, the range of pivot motion of the first base extension  106  between the closed end  316  and the opened end  314  within the groove  302  can range from about 0 to 90 degrees. However in some aspects, the range of pivot motion of each and/or some of the base extensions from the closed end to the opened end of a respective groove can range from about 0 to 180 degrees. In some aspects the range of pivot motion of the base extensions can be the same, while in other aspects the range of pivot motion can be different for the base extensions. 
     The first base extension  106  is coupled to the first base extension hinge  108  by a pin  318 , such that the first base extension  106  is adapted to pivot within the groove  302  about the pivot  304 . The pivot  304  is at a first position  321  of the first base extension hinge  108 , and the first base extension  106  is configured to substantially align the pin  318  with the pivot  304  at the first position  321 . Aligning the pin  318  with the pivot  304  allows the first base extension  106  to pivot about the pivot  304  within the groove  302 . When the first base extension  106  is pivoted within the groove  302  and positioned at the opened end  314  of the groove  302  such that the pin  318  is substantially aligned with the pivot  304 , as shown in  FIG. 10 , the first base extension  106  is set in a position to engage the locking mechanism within the first base extension hinge  108 . The first base extension  106  engaging the locking mechanism within the first base extension hinge  108  substantially locks the first base extension  106  within the first base extension hinge  108 , thereby fully deploying the first base extension  106 . 
     With reference to  FIGS. 11 and 12 , the first base extension hinge  108  can further comprise a channel  319  and at least one trench  320 . The channel  319  is configured to receive at least part of the first base extension  106 . In the aspects of  FIGS. 11 and 12 , the channel  319  is shaped to substantially correspond with the shape of the first base extension  106 . However, in some aspects, the channel  319  can have a shape that does not substantially correspond to the shape of the first base extension, and is not intended to be limited to the aspects disclosed herein. In some aspects, the channel  319  can have a shape that is different than the shape of the first base extension  106 . The at least one trench  320  extends from the pivot  304  or first position  321  towards a trench end  322 , wherein the at least one trench  320  is configured to receive part of the pin  318 . The at least one trench  320  allows the pin  318  to travel within the at least one trench  320  between the pivot  304  or first position  321  and the trench end  322 . The pin  318  extends through the first base extension  106  and into the at least one trench  320  of the first base extension hinge  108 , such that the first base extension  106  is arranged to be inserted into the channel  319  and engage the locking mechanism. In the aspect of  FIG. 11 , the first base extension  106  is positioned at the opened end  314  of the groove  302  such that the pin  318  is at the first position  321 , wherein the first base extension  106  is configured to be slidably received within the channel  319  of the first base extension hinge  108  and substantially locked within the first base extension hinge  108 . In the aspect of  FIG. 12 , the first base extension  106  has been inserted into the first base extension hinge  108  and slidably received within the channel  319 , such that the pin  318  has traveled within the at least one trench  320  from the first position  321  to the trench end  322 . The pin  318  is configured to travel within the at least one trench  320  between the pivot  304  or first position  321  and the trench end  322  within the channel  319 , wherein the first base extension  106  is locked and secured when the pin  318  is at the trench end  322 . The locking mechanism of the first base extension hinge  108  can be configured in many different ways to substantially lock the first base extension  106  within the first base extension hinge  108 . In some aspects, the channel  319  can be tapered from the first position  321  to the trench end  322  such that the channel  319  applies a compression force onto one or more surfaces of the first base extension  106  to lock the first base extension  106  within the channel  319  of the first base extension hinge  108 . In some aspects, the at least one trench  320  can be tapered from the first position  321  to the trench end  322  such that the at least one trench  320  applies a compression force onto the pin  318  to lock the first base extension  106  within the channel  319  of the first base extension hinge  108 . In some aspects, both the channel  319  and the at least one trench  320  can be tapered to lock the first base extension  106  within the first base extension hinge  108 . In yet some aspects, the channel  319  and/or the at least one trench  320  can comprise one or more tabs that extend from the channel and/or the at least one trench that catch and/or abut the pin  318  and/or the first base extension  106  to lock the first base extension  106  within the first base extension hinge  108 . In some aspects, the first base extension hinge  108  can comprise a tongue  324  within the channel  319  and proximate the trench end  322 , wherein the tongue  324  is received by the first base extension  106  to assist in locking and/or prevent the first base extension  106  from substantially moving. The locking mechanism of the first base extension hinge  108  can be configured to comprise any one or more of the above configurations, and is not intended to be limited to the aspects discloses herein. 
     In the aspects of  FIGS. 11 and 12 , the pin  318  extends through opposing surfaces of the first base extension  106  such that a first part of the pin  318  extends from an upper surface of the first base extension, and a second part of the pin  318  extends from a lower surface of the first base extension. The at least one trench  320  comprises two trenches  320  on opposing surfaces of the channel  319 , wherein each trench  320  receives the first and second parts of the pin  318 . The trenches  320  allows the pin to slidably traverse the trenches, such that the first base extension  106  can be slidably inserted and/or slidably retracted from the first base extension hinge  108 . The at least one trench  320  is substantially axially aligned with the first base extension  106  when the first base extension has been pivoted to the opened end  314  of the groove  302 , which assists to properly align the first base extension  106  when deployed. 
     The first base extension hinge  108  further comprises an opening  326  to receive the first support portion  104 , as shown in  FIG. 7 . The opening  326  comprises a top  328 , a base  330 , a sidewall  332 , at least one rib  334 , and a back wall  336 , wherein the opening  326  is proximate the groove  302  of the first base extension hinge  108 . The first support portion  104  is inserted into the opening  326  until the first support portion reaches the back wall  336  of the opening  326 . The at least one rib  334  assists in securing the first support portion within the opening  326 . In some aspects, the at least one rib  334  can be arranged within the opening  326  such that the opening  326  can accommodate the dimensions of the first support portion  104  that is received within the opening  326 . In other aspects, the at least one rib  334  can be arranged within the opening  326  such that part of the first support portion  104  received within the opening  326  at least partially contacts at least one of the top  328 , base  330 , sidewall  332 , and/or a combination thereof. The at least one rib  334  at least partially extends along the length of the opening  326  to the back wall  336 . The at least one rib  334  can be a continuous rib. In some aspects, the at least one rib  334  can comprise a plurality of ribs that are separated and aligned to form the at least one rib. In some aspects, the opening  326  can comprise a plurality of ribs  334  that contact part of the first support portion  104  that is received in the opening  326  such that the plurality of ribs  334  prevent the first support portion  104  from shifting and/or moving while in the opening  326 . In some aspects, the at least one rib  334  can be on the top  328  and/or base  330 . However, the at least one rib  334  can be arranged on many different locations within the opening  326  and is not intended to be limited to the aspects described herein. For example, in some aspects, the at least one rib  334  can be on the sidewall  332 , or on the top  328 , or on the base  330 , or on the back wall  336 , and/or a combination thereof. The first base extension hinge  106  can further comprise a lock pin to couple the first support portion  104  within the opening  326 . The lock pin can be at a bottom surface of the first base extension hinge  108 . However, the lock pin is not intended to be limited to the aspects described herein. In some aspects, the lock pin can be at the top surface or any other surface of the first base extension hinge  108  in order to couple the first support portion  04  to the opening  326 . The first support portion can be coupled or fixedly attached to the first base extension hinge  108  using many different fasteners known in the art, and is not intended to be limited to a lock pin. 
     The first base extension hinge  108  can further comprise a cavity  338 , wherein the cavity  338  is interposed between the groove  302  and the opening  326 . With reference to  FIG. 14 , the at least one rib  334  separates the opening  326  and the cavity  338 . The groove sidewall  306  separates the groove  302  and the cavity  338 . The cavity  338  also comprises the back wall  336 , such that the back wall  336  is shared between the opening  326  and the cavity  338 . The back wall  336  extends between the sidewall  332  of the opening  326  and the groove sidewall  306  of the groove  302 . The cavity  338  provides a separation between the opening  326  and the groove  302  to allow for the first support portion  104  to be separated from the first base extension  106  when the first base extension  106  is positioned at the closed end  316  within the groove  302 . The separation between the first support portion  104  and the first base extension  106  prevents the first base extension  106  from hitting and/or striking the first support portion  104  when being positioned into and/or when positioned at the closed end  316 . The separation assists in preventing damage to either the first support portion  104  and/or the first base extension  106 , which can prolong the durability of the ball net structure  100 . 
     At least one advantage of the disclosure is that the back wall  336  of the opening  326  is arranged to assist in securing the first base extension  106  within the first base extension hinge  108 . The back wall  336  extends from the sidewall  332  of the opening  326  towards the groove sidewall  306 , such that the back wall  336  provides a physical barrier within the channel  319  of the first base extension hinge  108  which assists in preventing the first base extension  106  from moving, pivoting, and/or becoming dislodged when fully received in the channel  319 . The back wall  336  provides an extended surface within the channel  319  that can abut part of the first base extension  106  within the channel  319 , such that the back wall  336  prevents the first base extension from pivoting. The first base extension  106  does not pivot when positioned proximate the trench end  322  due, in part, to the back wall  336 . In addition, the back wall  336  can also withstand at least some of the forces and/or loads exerted onto at least the base extension hinge  108  and/or base extension  106 , due to repeated strikes from a ball, bat, kicks from users while using the net, and the like that could cause typical locking buttons/pins to malfunction and/or fail. As such, the disclosure eliminates the need of using a typical locking button/pin. 
     Furthermore, in aspects comprising the tongue  324 , for example  FIG. 13 or 15 , the first base extension  106  comprises a hollow end, wherein the hollow end receives the tongue  324 , such that part of the first base extension  106  is interposed between the tongue  324  and the back wall  336 . The tongue  324  and back wall  336  configuration cooperate to prevent the first base extension  106  from moving and/or pivoting when interposed between the tongue  324  and back wall  336 . The tongue  324  and back wall  336  configuration provide further support against forces and/or loads exerted onto at least the base extension hinge  108  and/or base extension  106 . The tongue  324  can extend from any surface within the channel  319  and be proximate the back wall  336 , such that the first base extension  106  is interposed between the back wall  336  and the tongue  324 . In the aspects of  FIGS. 13 and 15 , the tongue  324  extends from a back channel wall  325  adjacent the back wall  336  in a direction parallel to the back wall  336 . The tongue  324  can comprise at least one finger  327  extending between the tongue  325  and a side channel wall  329  that is opposite the back wall  336  and adjacent the back channel wall  325 . The at least one finger  327  assists in providing structural support to the tongue  324 . The at least one finger can also extend from the back channel wall  325  and the side channel wall  329  to further assist in providing structural support to the tongue  324 . The hollow end of the first base extension  106  can be configured to accommodate the at least one finger  327 . In the aspect of  FIGS. 13 and 15 , the tongue  324  comprises two fingers  327 , but the tongue  324  can comprise one or more fingers  327  and is not intended to be limited to the aspects disclosed herein. 
     The tongue  324  is configured to provide a chamber  331  between the back wall  336  and the tongue  324 , wherein the chamber  331  is configured to receive part of the hollow end of the first base extension  106 . The chamber  331  receiving part of the hollow end of the first base extension  106  results in the presence of two structures, namely the tongue  324  and the back wall  336 , that function to prevent the first base extension  106  from substantially moving. The tongue  324  and/or back wall  336  act as barriers which prevent rotational movement of the first base extension  106  when the hollow end of the first base extension  106  is substantially received within the chamber  331 . The tongue  324  and back wall  336  configuration maintain the positioning of the first base extension  106  when fully deployed and the ball net structure  100  is in use. Strikes from users kicking the ball net structure  100  typically occur along the side of the first base extension, which imparts a rotational force onto the first base extension, but the tongue  324  and back wall  336  are able to withstand the force imparted by users kicking the first base extension such that the first base extension remains within the first base extension hinge  108 . Even if the first base extension  106  and/or the first base extension hinge  108  and/or any other component of the ball net structure were to receive a strike that caused the first base extension  106  to be released from the tongue/back wall or any other internal locking mechanism of the first base extension hinge  108 , the one or more stops  312  can act to at least partially prevent the first base extension  106  from substantial movement. The one or more stops  312  are another form of internal locking mechanism that can be used to hold the first base extension and/or slow down the rate at which the first base extension pivots within the groove. The one or more stops  312  would be helpful in the event that the first base extension  106  was inadvertently released from within the first base extension hinge  108 . The hollow end of the first base extension  106  can be released from tongue  324  and back wall  336  via lateral movement, namely sliding the first base extension  106  and pin  318  along the trench  320  until the pin  318  reaches the pivot  304 , when so desired to collapse the ball net structure  100 . In some aspects, the separation between the tongue  324  and the back wall  336  is constant. In some aspects, the separation between the tongue  324  and the back wall  336  decreases, such that the chamber  331  is tapered. The hollow end of the first base extension  106  when received by the tapered chamber  331  is wedged between the tongue  324  and the back wall  336 . At least one advantage of the disclosure is that the first base extension hinge  108  comprises locking features that are internal and are not exposed and/or external to the first base extension hinge  108 . The internal locking features, such as but not limited to the trench, the pin, the back wall, tongue, and/or chamber, alone or in combination, operate to lock the extension within the bracket and are able to withstand forces exerted onto the ball net structure  100 . Yet another advantage of the disclosure is that the first base extension  106  can be easily locked within the first base extension hinge  108  by sliding the first base extension into the channel of the first base extension hinge. The arrangement of sliding the first base extension into the first base extension hinge allows for the first base extension to be easily locked and released, such that an individual can easily deploy and/or collapse the net structure  100 . The arrangement of the first base extension hinge eliminates the need for external locking mechanism that introduce external moving parts that could fail and/or be lost that could render the net structure useless. Conventional locking features are at least partially exposed and are susceptible to failing due to repeated strikes from balls, kicks from users, and/or mechanical failure. The first base extension hinge  108  overcomes the disadvantages of conventional external locking features, and thereby reduces the potential for damage to the ball net structure  100  due to normal usage and also prolongs the durability of the ball net structure  100 . 
     The first base extension hinge  108  can further comprise at least one attachment device (not shown) to assist in stabilizing the ball net structure  100  to a surface. The attachment device can be an extension that extends from a bottom surface of the first base extension hinge, wherein the attachment device is configured to receive an attachment cord adapted to provide additional structural support. The attachment device can be similar to the attachment device  35  discussed above. In some aspects, the attachment device can be arranged to receive part of the net. The at least one attachment device is configured to provide additional structural support to the ball net structure  100  which increases the stability and/or the force the ball net structure  100  can withstand. Furthermore, the at least one attachment device can also be used to maintain the positioning of the ball net structure to prevent shifting of the ball net structure. In some aspects, the ball net structure comprises a plurality of attachment devices and can be on the first support portion  104  and/or the first base extension  106 . In yet some aspects, the attachment device can be located on different locations on the first base extension hinge  108  and is not intended to be limited to being at the bottom surface. In yet some aspects, an attachment device can be on at least one of the first support portion  104 , first base extension hinge  108 , first base extension  106 , the base hinge  110 , and/or a combination thereof. 
     With reference to  FIG. 7 , the first base extension hinge  108  further comprises a shaft  340  extending from a top surface  342  of the first base extension hinge  108 . The shaft  340  extends outward in at least a direction towards a back surface  333  of the first base extension hinge  108  opposite the first base extension  106 . In some aspects, the shaft  340  can be angled at an angle θ (theta) with respect to the back surface  333  of the first base extension hinge  108 . In some aspects, the shaft  340  can be angled at an angle θ within the range of 0 and 90 degrees. The shaft  340  can extend outward with respect to more than one surface of the first base extension hinge  108 . In some aspects, the shaft  340  can extend outward in a direction towards the base surface  333  of the base extension hinge  108  and in a direction towards a side surface  317  of the base extension hinge  108 . The shaft  340  can be configured to extend out in different directions based on where the shaft  340  is located on the base structure  102 , based on the shape of the net  114 , and/or where the resultant force from the rods  112  needs to be transferred towards the base structure  102 . In some aspects, the shaft  340  can comprise at least one fin  344 , wherein the at least one fin  344  provides structural support to the first base extension hinge  108  and/or the shaft  340 . The at least one fin  344  can comprise a planar body  346  that is coupled to the shaft  340  and to part of the top surface  342  of the first base extension hinge  108 . The at least one fin  344  assists in stabilizing the shaft  340  and to withstand forces exerted onto the shaft  340 . The at least one fin  344  can also assist in withstanding forces exerted onto any part of the ball net structure  100 , such as but not limited to the base extension hinge, base extension, support portion, and/or any elements of the ball net structure  100 . In the aspects of  FIGS. 6-15 , the shaft  340  comprises four fins  344 . However, in other aspects, the shaft  340  can comprise one or more fins  344  and is not intended to be limited to the aspects disclosed herein. In some aspects, the at least one fin  344  can comprise an attachment device  350  (not shown), similarly as disclosed above and/or as shown in  FIGS. 16 and 17 , discussed below. The attachment device  350  of the at least one fin  344  can be configured to receive the attachment cord as discussed above to stabilize the ball net structure  100 . While in other aspects, the attachment device  350  of the at least one fin  344  can receive part of a net  114 . The attachment device  350  of the at least one fin  344  can be configured in many different ways and is not intended to be limited to the aspects disclosed herein. In some aspects, the attachment device  350  of the at least one fin  344  can comprise at least one tab extending from the planar body  346 . In some aspects, the attachment device  350  of the at least one fin  344  comprises a notch formed within the planar body  346 . In yet some aspects, the attachment device  350  of the at least one fin  344  comprises an aperture in the planar body  346  and a stud within the aperture extending from the planar body  346 . The shaft  340  is disclosed as extending from the top surface  342  of the first base extension hinge  108 , but the disclosure is not intended to be limited to the aspects disclosed herein. In some aspects, the shaft  340  can extend from any surface of the first base extension hinge  108 , such as but not limited to a side surface, a bottom surface, or a combination thereof. 
     The shaft  340  of the first base extension hinge  108  is configured to receive a rod  112 . The rod  112  is securely held within the shaft  340  such that the shaft maintains a stable structural connection between the shaft and the rod  112 , and prevents the rod from being removed from the shaft when the ball net structure  100  is assembled. In one aspect of the disclosure, the shaft  340  is similarly shaped as the rod  112 , such as but not limited to cylindrically shaped, and can be larger than the rod  112  such that the rod can be easily received by and/or removed from the shaft  340 . In some aspects, the shaft can comprise a sheath contacting at least part of an inner wall of the shaft that receives the rod. The sheath is adapted to protect the rod within the shaft from forces exerted on the rod. As discussed above in the aspects of  FIGS. 1-4 , and discussed below, the rods  112  experience a moment force proximate where the rod  112  is received by the shaft  340 , and causes the rod to exert a compression force upon the inner surface of the shaft. The sheath, if present, protects the rod from the forces exerted on and/or by the rod. 
     The shaft  340  can be arranged in many different ways and is not intended to be limited to the aspects disclosed herein. In some aspects, the shaft  340  can comprise a tapered inner surface such that the radius of the shaft decreases as the rod is further inserted into the shaft. In such aspect, the shaft applies a compression force onto the rod to form a structural connection with the rod. In other aspects, mechanical devices, such as but not limited to, screws, nuts, nails, rivets or the like, can be used to form the structural connection to securely attach the rod to the shaft. In yet other aspects, the rods can comprise an attachment device such that the rods can be attached to the shaft; non-limiting examples of such attachment devices are the rods being threaded and screwed into the shaft or the rod and shaft configured similarly like a bayonet-type locking device. 
     In the aspect of  FIG. 5 , the rods are circularly shaped and the shaft is also correspondingly circularly shaped to receive the rod. The shape of the rod and shaft is not intended to be limited to a circular shape, other shapes such as quadrilateral, triangular, or any other polygonal shape can be used. The shaft can also be similarly shaped as the rod, but in some aspects, the shaft can be shaped differently than the rod. The rods can be made of many different materials known in the art, such as but not limited to fiberglass or carbon fiber, such that the rods are flexible, elastic, capable of returning to an initial form or state after deformation, and able to withstand the impact forces applied by sports-related balls and/or other projectiles that can be captured or caught by the ball net structure, or thrown, kicked, and/or hit towards the ball net structure. 
     The angle at which the shaft  340  is angled with respect to at least the back surface  333  of the first base extension hinge  108  causes the rod to extend outward at substantially the same angle as that of the shaft  340 . The rods  112 , when received by the shaft  340  flare outwards, such that the rods are in a relaxed state and are substantially straight, as shown in  FIG. 6 . A net  114  is arranged to receive the at least one rod  112  of the ball net structure  100 . In some aspects, the net  114  comprises at least one sleeve  113  to receive part of at least one rod  112  of the ball net structure  100 . The net  114  is adapted to exert a force on the at least one rod  112  bending the at least one rod into a flexed state. The at least one rod received by the at least one sleeve  113  results in the at least one rod being bent from the relaxed state into a flexed state. In the aspect of  FIG. 5 , the ball net structure  100  comprises four rods  112 , wherein each rod is received by a respective shaft  340  and at least one respective sleeve  113  of the net  114 , such that the rods  112  are bent in a direction towards the base structure  102  and into the flexed state. The net tension exerted by the net  114  onto the rods  112  simultaneously pulls the rods into the arcuate state, such that the rods are maintained in the arcuate state when the net structure  100  is fully assembled. Removal of the net  114  from the rods  112  allows the rods to return to their original form of the relaxed state. When the rods  112  are in the relaxed state, the rods can be easily removed from the shaft and allows the ball net structure  100  to be disassembled and stored for later use. Repeated use of the ball net structure does not result in the rods being permanently bent in a shape similar to that of the flexed state. In some aspects, when the rods are in the relaxed state, the base structure can be configured into a different configuration to allow a different net to be used with the base structure. 
     The net  114  can be configured in a manner that is similar to the net  30 , discussed above. The net  114  imparts a pulling force on each of the rods which causes the rods to bend into the arcuate state, such that the rods are bent in a direction towards the base structure. Once bent towards the base structure, the rods are in the flexed or arcuate state and experience a moment force about its pivot point. The rods while in the arcuate state are biased away from the other rods to hold the net upright. The pivot point of each of the rods, in the aspect of  FIG. 5 , corresponds to the point at which the rods are received by the shaft. The moment force experienced by the rods is imparted and/or transferred onto at least the support portion  602  and the first and second base extensions, with the transferred force being greatest at a central region of the support portion  602 . This transferred force further assists in stabilizing the base structure on the surface which the ball net structure is on. The rods can also exert a force onto the base hinge  110  to lock the first and second support portions  104 ,  116 , such that the transferred force prevents rotation of the first and/or second support portion about the respective pivots of the base hinge  110 . The ball net structure  100 , when fully assembled and deployed, is adapted to withstand the force of a ball or projectile to capture the ball while keeping the support portions locked at the base hinge  110 , the first and second base extensions  106 ,  118  locked within the respective first and second base extension hinges  108 ,  120  and the ball net structure  100  upright. The base hinge  110  of the ball net structure  100  is similar to the hinge  22  shown in the aspects of at least  FIGS. 1-4 , wherein the base hinge  110  does not comprise a locking device and is locked due to the forces exerted by the net and/or rods when the ball net structure  100  is fully assembled. As such, the first and second support portions do not pivot about the pivots of the base hinge due to the forces exerted by the net and/or rods. 
     The net can comprise a mesh surface and/or can be comprised of typical net materials known in the art. The net comprises at least one sleeve  113  to receive a rod. In the aspect of  FIG. 5 , the net  114  comprises a plurality of sleeves  113  configured in different configurations. At least one pair of sleeves  113  at least partially extend along opposing edges of the net  114  that are configured to receive the rods  112  received by the base extension brackets  200 , such that the sleeves  113  are opposite each other. The sleeves  113  that receive the rods  112  from the base extension brackets  200  are elongated sleeves  113  and substantially cover and/or receive all of the rod extending from the base extension brackets  200 . Some of the other sleeves  113  of the net  114  can be configured similar to loops and receive part of the rod and/or part of the base structure. The sleeves  113  of the aspect of  FIG. 5  are in the form of sleeves of varying sizes that are adapted to receive a respective rod  112  and/or part of the base structure  102 . For example, the net comprises front elongated sleeves  113  that receive the rods  112  extending from the base extension brackets  200 . The front elongated sleeves  113  are coupled to and extend along part of the edge of the net extending between the base extensions and the upper end  502  of the rods  112  extending from the base extension brackets  200  while covering substantially all of the rods extending from the base extension brackets  200 . The net further comprises smaller sleeves or loops proximate the front elongated sleeves, wherein upper loops  113  receive the upper ends  502  of the rods  112  extending from the base extension brackets  200  and lower loops  113  receive the base extensions and/or the base extension bracket  200 . The net  114  further comprises rear upper loops  113  that receive an upper end  502  of the rods  112  that extend from the first and second base extension hinges  108 ,  120  and are proximate a respective corner region of the net. The net  114  further comprises an elongated sleeve  113  along the base of the net that is configured to receive the base structure  102 . The elongated sleeve along the base of the net  114  covers substantially all of the first base extension  106 , the first and second support portions  104 ,  116 , and the second base extension  118 . This elongated sleeve along the base of the net is configured to accommodate the first and second base extension hinges  108 ,  120  and the base hinge  110 , such that the base extension hinges and the base hinge are not covered by the elongated sleeve. The elongated sleeve can be configured to accommodate the base extension bracket  200 , such that the sleeve can comprise an opening to allow the base extension bracket  200  to extend out from the elongated sleeve to allow the lower end  504  of the rod to be received by the shaft  340 . The elongated sleeve allows the base extension hinges to be exposed and are not covered by the elongated sleeve, to accommodate for the shaft  340  on the base extension hinges. The elongated sleeve also allows the base hinge to be exposed and not covered by the elongated sleeve in order to allow the first and/or second support portions to pivot about the base hinge  110 . The base hinge being exposed and uncovered allows the first and/or second support portions to pivot within the base hinge in order to collapse the base structure and store the base net structure with the net remaining on the base structure. This allows the base net structure to be collapsed and stored without having to remove the net from the base structure. The base extension hinges being uncovered by the elongated sleeve also allows the base extensions to pivot within the groove of the base extension hinges in order to collapse the base extensions. The elongated sleeve that receives the base structure comprises at least one strip that allows the base extension hinges and base hinge to be exposed and uncovered by the elongated sleeve. The elongated sleeve comprises two corner strips and a center strip, wherein each corner strip connects the sleeve between the base extensions and the support portions. The corner strips extend behind the base extension hinges exposing the base extension hinges. The center strip connects the sleeve between the first and second support portions and extends behind the base hinge in order to expose the base hinge. The corner and/or center strips are disclosed as extending behind the base extension hinges or the base hinge. However, the disclosure is not intended to be limited to the aspects disclose herein. In some aspects, the corner and/or center strips can extend in front of, under, and/or above the base extension hinges and/or base hinge such that the base extension hinges and/or base hinge are exposed and not covered by the elongated sleeve. The net  114  can comprise at least one seam extending between the corner strip and the upper loop  113  that receive the upper end  502  of the rods from the base extension hinges  108 ,  120 . In the aspect of  FIG. 5 , the net  114  comprises a first seam and a second seam, wherein the first seam extends between the corner strip adjacent the first base extension hinge  108  and the upper end  502  of the rod received by the first base extension hinge  108 . The second seam extends between the corner strip adjacent the second base extension hinge  120  and the upper end  502  of the rod received by the second base extension hinge  120 . The seams assist the net  114  in forming a soccer like goal with distinct net sides and/or net surfaces that are substantially taut and do not substantially sag when the ball net structure  100  is fully assembled. 
     The front elongated sleeves are adapted to extend along part of the rods that extend from the base extension brackets  200 , and the smaller sleeves or loops are adapted to be removably coupled to an end of the rod and/or base structure. The sleeves of the net can be configured in many different configurations and are not intended to be limited to the aspects disclosed herein. In some aspects, the sleeve can span the length of the rod. In other aspects, the sleeve can comprise a plurality of smaller sleeves or loops that are spaced apart from each other and run along part of the rods, or can comprise a sleeve that spans along a partial length of the rod, or can comprise a plurality of sleeves of various lengths. The sleeves of the net can be arranged in many different configurations, such as but not limited to at least one sleeve that extends along a substantial portion of the rod, a plurality of sleeves that extend along part of the rod, or a combination thereof. In some aspects, the sleeves are fixedly attached to the net. In some aspects, the sleeves comprise an attachment mechanism in order to removably couple the sleeves to the rod and/or base structure. In some aspects, the attachment mechanism can comprise a hook and loop system, such that the sleeves are removably coupled via the hook and loop system. In other aspects, the attachment mechanism can comprise a hook, latch, or the like in order to removably couple the sleeve. The sleeves receive the rods and securely hold the net on the rods due in part to the sleeves bending the rods. 
     The base extension hinges can comprise an extension at a back surface of the base extension hinges that allows for connection of the at least one sleeve to the extension. The extension can be at many different locations on the base extension hinges and is not intended to be limited to the back surface. In other aspects, the extension can be on any part of the base structure, such as but not limited to the first and/or second support portions, the first and/or second base extensions, or a combination thereof. In some aspects, the base structure can comprise a plurality of extensions to allow for the connection of at least one sleeve. In some aspects, the at least one attachment device can also be configured to receive part of the net and/or at least one sleeve. In some aspects, the net can comprise at least one sleeve adapted to receive part of at least one of the first and second support portions. While in other aspects, the net can comprise a plurality of sleeves that receive a respective one of the first and second support portions. The sleeves that receive the support portions can extend along the base or lower edge of the net that is proximate the support portion. The sleeves of the net can be comprised of many different materials, such as but not limited to fabric, plastic, elastic material, rope, cord, or the like. 
     In the aspect of  FIG. 5 , the front elongated sleeves and the elongated sleeve that receives the base structure  102  can be configured to give the appearance of a wide and/or solid borders. The wide and/or solid borders can make it easier for users to visually identify the size of the ball net structure. The borders can comprise graphics and/or printed matter to assist in proper alignment of the net during assembly. The borders can provide a visual indication of the profile of the net such that users can identify the boundary of the net that is intended to capture the ball and/or other projectile. The net is held onto the rods and base structure by tension. The tension holds the net substantially taut, such that the net can capture a ball and/or other projectile. The net being substantially taut allows the borders to be easily visible. The net  114  of  FIG. 5  is configured to be a soccer goal, wherein the net comprises two sidewalls, a back wall and a top wall. However, the net  114  is not intended to be limited to a soccer goal. The net  114  can be configured to be many different nets, such as but not limited to hockey goals, lacrosse goals, baseball nets, volleyball nets, barrier nets, and the like. 
     Each rod can comprise an endcap opposite the portion of the rod that is received by the shaft. The endcap is configured to receive at least a portion of the sleeve and/or loop, such that the endcap prevents the net from coming off the rods while the ball net structure is assembled and/or in use. In one aspect, the endcaps comprise a tab and a notch that prevents the net from coming off the rod. For example, the endcap comprises a tab and a notch proximate the tab, such that the notch provides a depressed surface that receives the sleeve and/or loop such that the sleeve and/or loop is securely held by the endcap within the notch. In yet other aspects, the net can comprise a keyhole clip configured to be removably coupled to the endcap. In one aspect, the keyhole clip comprises a housing comprising an opening, a groove, and a cover, wherein the keyhole clip is received by the endcap. In one aspect, the tab of the endcap is received by the opening the keyhole clip and is slidably received with the groove, such that the notch of the endcap is sized to fit and be removably coupled to the groove of the keyhole clip. The keyhole clip is thereby securely held by the endcap and is prevented from coming off the endcap while the ball net structure is assembled and/or in use. The cover of the housing covers the groove and opening, such that when the keyhole clip is received by the endcap, the cover covers the endcap and assists in maintaining the net on the rod. At least one advantage is that the keyhole clip provides for ease of installing and/or coupling the net onto the rods. In addition, the keyhole clip being securely held by the endcap assists in keeping the net on the rods in the event that a ball and/or other projectile hits the net proximate the endcap. However, in other aspects, the endcaps can have other means of preventing the net from coming off the rods, such as but not limited to a hook, loop, locking clip, or the like. 
     At least one advantage of the disclosure is that the base structure can compensate for forces exerted onto the base structure by the rods while in the flexed state. When the net is coupled and/or received by the rods that are within the respective shafts, the net exerts a pulling force onto the rods, such that the rods are in the flexed state. The rods in the flexed state exert a force onto at least the support portions of the base structure. The base structure can absorb the load exerted onto the support portions due to the rods being in the flexed state and distribute the load across the base structure. In some aspects, the first and/or second support portions can be bent to at least partially raise part of the first and/or second support portions in order to counteract the downward force exerted onto the base structure by the rods bent in the flexed state. In some aspects, the base extensions can be bent to raise the base structure when the base extensions are deployed. In some aspects, the base extension hinges can have at least one angled portion that receives either the base extension and/or the support portions, such that the angled portions cause the support portions and/or the base extensions to lift the base extension hinges when the ball net structure is fully deployed. The base extension hinges are disclosed as having one base extension. However, the base extension hinges can be configured to have more than on base extension and more than one groove, and is not intended to be limited to the aspects disclosed herein. 
     The base extensions can be configured in many different configurations and are not intended to be limited to the aspects of the disclosure herein. The base extensions of at least  FIG. 6  are shown as being straight or linear. However, the base extensions are not intended to be limited to being straight or linear. In some aspects, the base extensions can be bent such that the bent base extensions raise the base structure off the ground or surface by the distance “d” when the base extensions are deployed. The bent base extension could be used with the angled hinge bracket to further assist in lifting the base structure from the ground or surface. In some aspects, the base extensions and/or the support portions can be bent such that the base structure is at least partially raised off the ground or surface. The base extension hinges can further comprise feet that lift the base extension hinges off the ground or surface such that at least the support portions are raised off the ground or surface. 
     The base extension hinge can be configured in many different configurations and is not intended to be limited to the aspects disclosed herein. For example, in some aspects, the base extension hinge has a circular shape, but in other aspects, the base extension hinge can comprise many different shapes and not limited to a circular shape. In other aspects, the base extension hinge can comprise one groove or more than one groove. For example, the base extension hinge can comprise two grooves and a base extension pivotable within a respective groove. Additionally, the grooves can be set at an angle such that the bottom surface of the base extension hinge is not substantially flat. The angled grooves of the base extension hinge can cause the base extensions to lift the base structure when the base extensions are deployed or positioned at the opened end of the groove. Furthermore, the stop within the groove can be a raised surface that corresponds to the shape of the base extensions to prevent rotation of the base extension within the groove. The base extension hinge can be formed of many different materials. In one aspect, the base extension hinge can be comprised of plastic materials, fabricated using an injection molding process. An advantage of the disclosure is that the base extension hinge is of solid construction and is not formed of separate components that are joined together. The unitary construction of the base extension hinges results in a stronger device and can bear the load of the rods exerted onto the base structure. 
       FIGS. 16 and 17  show one aspect of a base extension bracket according to the disclosure. 
     The base structure  102  can further comprise a base extension bracket  200  on the first and second base extensions  106 ,  118 . The base extension bracket  200  is on an end  616 ,  618  of the base extensions opposite the base extension hinges. The base extension bracket  200  is configured to receive at least one rod  112 . The base extension bracket comprises a shaft  340  that can be configured similar to the shaft  340  of the first and second base extension hinges  108 ,  120 . The shaft  340  of the base extension brackets  200  extend outwards in at least a direction away from the opposing first and second support portions. The shafts  340  of the base extension brackets  200  can also be configured to extend outwards in at least a direction away from the opposing base extension bracket  200 . The base extension bracket  200  receives at least one rod, wherein the at least one rod is received by the net  114 . The base extension bracket  200  can comprise at least one fin  344 , as discussed above, and can comprise an attachment device  350 . The attachment device  350  can be arranged to be a tab extending from a planar body  346  of a fin  344  such that the tab can receive part of the net  114  and/or an attachment cord that is arranged to stabilize the ball net structure to the surface. 
     The shaft  340  of the base extension bracket  200  extends from an upper surface  202  of the base extension bracket  200 . The at least one fin  344  can be coupled to the shaft and at least the upper surface  202  of the base extension bracket. In some aspects, the at least one fin  344  can also be coupled to a side wall  204  of the base extension bracket  200 . In the aspect of  FIGS. 16 and 17 , the shaft  340  comprises four fins  344 , wherein a pair of fins are coupled to the shaft  340  and the upper surface  202  opposite each other. The other pair of fins are coupled to the shaft  340 , the upper surface  202 , and the side wall  204  and are also opposite each other. The fins  344  provide structural support to the shaft  340  and/or the base extension bracket  200  in a manner similarly to the at least one fin  344  of the base extension hinges, discussed above. The base extension bracket  200  can be fixedly attached to the respective ends  616 ,  618  of the first and second base extensions. In some aspects, the base extension brackets  200  can be removably coupled to the ends  616 ,  618  such that a net having a different shape and/or configuration than the net  114  can be used with base structure  102 . This allows the base structure  102  to receive many different nets resulting in the base structure  102  being versatile and compatible with different nets such that a user could have different nets but only have one base structure to receive the different nets. 
     Although the disclosure has been described in considerable detail with reference to certain configurations thereof, other versions are possible. Ball net structures according to the disclosure can be many different sizes and can be used for many different applications, other than for sports-related activities. The ball net structure can comprise net sidewalls to form an enclosure, similar to a soccer goal, lacrosse goal or the like, wherein each base extension comprises a plurality of shafts that receive a respective one of a plurality of rods. The ball net structure can also include a plurality of hinges that lock its base structure to the hinge using the force exerted onto the hinge from the frame structure of the ball net structure. In other aspects, the support portions can be adjustable to make a smaller or bigger base structure, while the size of the rods can also be adjusted to make a smaller or bigger ball net structure. In other aspects, the rods can be made of a single piece of material, whereas in other aspects, the rods can be comprised of a plurality of rod pieces that are joined together to form the rod. Therefore, the spirit and scope of the disclosure should not be limited to the versions described above.
