     BACKGROUN D 
     Sportspersons, for example, players, trainers, coaches, etc., generally have a need to store various sports equipment that are large or bulky, or have shapes that are difficult to store in a compact and organized manner. For example, ball-shaped sports equipment such as basketballs, volleyballs, footballs, etc., need to be stored in a manner where they are readily retrievable and prevented from rolling away on a sports court where a game is being played. Conventional sports bags provide limited and suboptimal space to store and carry sports equipment, for example, balls of different sports such as basketball, volleyball, soccer, football, etc. Some sports bags comprise a separate external pouch to carry a single ball. Most sportspersons typically need to store more than a single ball, which makes a sports bag that is designed to accommodate a single ball inappropriate. Moreover, it is generally cumbersome to remove a ball from these types of sports bags, for example, due to the fastening mechanisms that are used to secure the ball in the sports bag. 
     While some conventional sports racks allow storage of multiple balls therein, these sports racks are typically heavy cage-type structures that are configured for stationary or immovable storage. Due to their weight, structure, and difficulty in containing the balls stored therein, it is difficult to transport these sports racks, for example, move these sport racks on a sports court where a game is being played. Furthermore, most sports bags or sports racks store sports equipment horizontally as it is difficult to reach and retrieve the sports equipment, for example, balls, positioned towards the bottom of the sports bags or the sport racks when the sports bags or the sport racks are positioned in an upright position. Furthermore, a conventional sports rack is generally configured for storing sports equipment and not for facilitating the retrieval and use of the sports equipment stored in the sport rack on the sports court, for example, for allowing basketballs to be readily retrieved by a sportsperson practising on a basketball court, and for facilitating training of the sportsperson. 
     Hence, there is a long-felt need for a portable sports rack and delivery system and a method of use thereof for storing and transporting multiple sports equipment, for example, multiple balls of one or more sports such as basketball, volleyball, soccer, football, etc., in a compact and organized manner and in a substantially vertical position, while allowing convenient access to and ready retrieval of all balls stored therein, including the lowermost ball positioned at the bottom of a storage space defined therewithin. Furthermore, there is a need for a portable sports rack and delivery system and a method of use thereof for training sportspersons using the sports equipment stored therein and retrieved therefrom.

The cross-sectional view in  FIG. 7B  exemplarily illustrates the storage space  101   g  of the elongate rack enclosure  101 , ball-shaped sports equipment, for example, the basketballs  112   a ,  112   b ,  112   c ,  112   d , and  112   e  accommodated therewithin, the training component  105 , and two of the wheel assemblies, for example, the casters  104 , extending from the bottom surface  103   a  of the base member  103 . In an example, the thickness of the walls  101   j  and  101   k  of the elongate rack enclosure  101  exemplarily illustrated in  FIG. 7B  is about 1.5 inches. The cross-sectional view in  FIG. 7B  also exemplarily illustrates the release component  115  comprising the spring base  114  loaded with the compression spring  113 . The release component  115  is disposed and accommodated in the storage space  101   g  of the elongate rack enclosure  101  at the lower end  101   b  of the elongate rack enclosure  101 . The compression spring  113  is, for example, an open-coil helical spring. The compression spring  113  comprises a first end  113   a  and a second end  113   b . The first end  113   a  of the compression spring  113  is operably coupled to the base member  103 . The second end  113   b  of the compression spring  113  is operably coupled to the spring base  114 . As exemplarily illustrated in  FIG. 7B , a predetermined number of balls, for example, five basketballs  112   a ,  112   b ,  112   c ,  112   d , and  112   e , are stored in a substantially vertical orientation within the storage space  101   g  of the elongate rack enclosure  101 . The uppermost basketball  112   a  extends outwardly from the delivery opening  102  at the upper end  101   a  of the elongate rack enclosure  101 . The lowermost basketball  112   e  is positioned and accommodated on the curved upper surface  114   a  of the spring base  114 . The spring base  114 , in operable communication with the compression spring  113 , is configured to elevate the stacked. basketballs  112   b ,  112   c ,  112   d , and  112   e  remaining in the storage space  101   g  of the elongate rack enclosure  101  towards the delivery opening  102  when the uppermost basketball  112   a  is removed from the storage space  101   g  through the delivery opening  102  by a sportsperson, for example, a basketball player, a coach, a trainer, etc. 
     The compression spring  113  of the release component  115  is configured to resist compressive threes applied to the compression spring  113  by the load of the basketballs  112   a ,  112   b ,  112   c ,  112   d , and  112   e . When the uppermost basketball  112   a  is removed from the storage space  101   g  through the delivery opening  102  and a force is applied to the compression spring  113 , the compression spring  113  condenses or compresses, storing the force until the force is released to elevate the remaining basketballs  112   b ,  112   c ,  112   d , and  112   d  such that the next uppermost basketball  112   b  is released from the storage space  101   g  of the elongate rack enclosure  101  for delivery through the delivery opening  102 . When compressed in one direction, the compression spring  113  exerts force in the opposite direction as the compression spring  113  attempts to return to its resting length. The spring base  114  loaded with the compression spring  113  keeps the uppermost basketball, for example,  112   a , at the upper end  101   a  of the elongate rack enclosure  101 , so that when the uppermost basketball  112   a  is unloaded or removed from the storage space  101   g  through the delivery opening  102 , the spring base  114 , in operable communication with the compression spring  113 , elevates the remaining basketballs  112   b ,  112   c ,  112   d , and  112   e  to save the user, for example, a sportsperson, from bending down into the storage space  101   g  of the elongate rack enclosure  101  to retrieve the next uppermost basketball  112   b . The compression spring  113  takes the strain out of loading and/or unloading basketballs  112   a ,  112   b ,  112   c ,  112   d , and  112   e  or other sports equipment by lowering the load as sports equipment are added to the storage space  101   g  of the elongate rack enclosure  101 , and elevates the sports equipment as each item or piece of sports equipment is removed from the delivery opening  102 . When the user takes the uppermost basketball  112   a  out of the storage space  101   g  of the elongate rack enclosure  101 , the release component  115  elevates the next uppermost basketball  112   b  for ready retrieval.

When an operator of the portable sports rack and delivery system  100 , for example, a coach or a trainer, wishes to adjust the height of the training component  105 , the operator extends the inner telescopic member  127  that holds the support member  119  of the training component  105  in an upward direction such that the push button, that is in a compressed condition, is released into one of the openings in the outer telescopic member  126  corresponding to the required height, thereby locking the training component  105  at the required height. 
     To readjust the height, the operator presses the push button from the opening in the outer telescopic member  126 , which allows the inner telescopic member  127  to slide in an upward direction inside the outer telescopic member  126  with the push button in the compressed condition. The operator extends the inner telescopic member  127  to the next opening in the outer telescopic member  126  corresponding to the required height. On reaching the opening at the required height, the push button is released into the opening in the outer telescopic member  126 , thereby locking the training component  105  at the required height. Similarly, the operator readjusts the height of the training component  105  by pressing the push button from the opening in the outer telescopic member  126 , which allows the inner telescopic member  127  to slide in a downward direction inside the outer telescopic member  126  with the push button in the compressed condition. The operator lowers the inner telescopic member  127  to the next opening in the outer telescopic member  126  corresponding to the required height. On reaching the opening at the required height, the push button is released into the opening in the outer telescopic member  126 , thereby locking the training component  105  at the required height. In other embodiments, other functionally equivalent methods and mechanisms for locking the training component  105  at a required height are used.
