FIELD OF THE INVENTION

[0002] The apparatus disclosed herein, in general, relates to disc sport training. More particularly, the apparatus disclosed herein relates to a portable training apparatus for allowing users to practice different shots or throws, for example, disc golf drives, approach shots, and putts.

BACKGROUND

[0003] Disc golf has become a growing sport in recent years. Unlike traditional golf that requires a golf club and a ball, disc golf is a flying disc sport in which players, referred to as disc golfers, throw a flying disc into each of a series of targets on an outdoor course, the objective being to complete a course using fewest possible throws. The targets are typically metal baskets with a chain net configured to catch the flying discs. Disc golf is typically played on an outdoor course composed of 9 or 18 holes. On each hole, players attempt to reach a target by throwing a flying disc towards the target, starting at a tee area or a tee pad. The target is reached only when the flying disc falls into the basket. The throw is repeated from where the flying disc landed on the first throw, until the flying disc is thrown into the basket. The number of throws made by a player to reach the target is recorded and compared with a par. The term “par” refers to an established, average number of throws expected from a player to hit the target. Most holes in disc golf are, for example, about 60 meters to about 150 meters long, and a player is typically allowed three shots or throws in order to make the par for the hole. The player who completes the course with the fewest number of throws wins the game.

[0004] Typical throws in disc golf comprise drives, approach shots, and putts. A drive typically refers to a first throw or shot from a tee pad or from a fairway designed for maximum distance. An approach shot, also referred to as an upshot, is typically the second throw or shot, after the initial drive, designed to position the flying disc within putting distance. A putt is the final throw, typically within a 10-meter radius of the target, aimed at getting the flying disc to fall into the basket. A conventional disc golf practice basket is only designed for putting practice. These practice baskets only allow players to practice their putts in their back yard or on the go. Currently, if a player wants to practice their drives and approach shots, the player has to travel to a disc golf course or an open field in order to throw their discs at a high speed without worrying about hitting anyone or causing any damage.

[0005] Furthermore, when players perform multiple repetitions (reps) of throws during training, the flying discs thrown typically collect and bundle up in pockets provided in conventional nets, after they hit the target, resulting in sagging of the nets, thereby disallowing players from training at a consistent level in their practice games.

[0006] Therefore, there is a long-felt need for a portable training apparatus that allows players to practice different shots or throws, for example, drives and approach shots, in their back yard or on the go, in addition to practicing their putts. Furthermore, there is a need for a mechanism that conveniently funnels sporting projectiles, for example, flying discs, that hit their target, and allows easy retrieval and removal of the sporting projectiles out of pockets of a net, to prevent sagging of the net. SUMMARY OF THE INVENTION

[0007] This summary is provided to introduce a selection of concepts in a simplified form that are further disclosed in the detailed description of the invention. This summary is not intended to determine the scope of the claimed subject matter.

[0008] The apparatus disclosed herein addresses the above-recited need for a portable training apparatus that allows players to practice different shots or throws, for example, drives and approach shots, in their back yard or on the go, in addition to practicing putts. The apparatus disclosed herein further addresses the above-recited need for a mechanism that conveniently funnels sporting projectiles, for example, flying discs, that hit their target, and allows easy retrieval and removal of the sporting projectiles out of pockets of a net, to prevent sagging of the net. The portable training apparatus is configured for training users, for example, players who play flying disc sports such as disc golf, also referred to as disc golfers. The portable training apparatus saves users a trip to a disc golf course for disc golf training and practice. Moreover, the portable training apparatus optimizes training sessions as the portable training apparatus reduces time it would take to find and retrieve the sporting projectiles in an open field, thereby allowing users to throw many more shots in a shorter amount of time and maximizing training sessions.

[0009] The portable training apparatus disclosed herein comprises a collapsible frame and a net. The collapsible frame comprises a pair of base supports, a pair of vertical poles, and a horizontal pole. The pair of base supports is configured to rest on a support surface, for example, a ground surface. In an embodiment, each of the pair of base supports is of a generally V-shape, where a mid-section of each of the pair of base supports corresponds to a vertex of the generally V-shape. The mid-section of one of the pair of base supports faces the mid-section of the other one of the pair of base supports when the collapsible frame is assembled. In an embodiment, the mid-section of each of the pair of base supports comprises a vertical holder and a horizontal holder. The horizontal holder is disposed substantially perpendicular to the vertical holder. The vertical holder is configured to secure one of the pair of vertical poles. The horizontal holder is configured to secure one end of the horizontal pole.

[0010] The pair of vertical poles corresponds to the pair of base supports. Each of the vertical poles is secured to the mid- section of a corresponding one of the base supports. Each of the vertical poles projects upwards from the corresponding one of the base supports.

[0012] The net is releasably secured to the pair of vertical poles and the horizontal pole of the collapsible frame. The net comprises one or more pockets built into the net and configured to retain a sporting projectile, for example, a golf disc, a ball, etc. Each pocket comprises a top opening integrated into the net for receiving the sporting projectile, and a bottom opening integrated into the net for allowing removal of the sporting projectile. In an embodiment, the top opening of the pocket(s) is substantially larger than the bottom opening of the pocket(s). The top opening of the pocket(s) is, for example, of one of a circular shape, a generally rectangular shape, a generally square shape, a polygonal shape, and an elliptical shape. The bottom opening of the pocket(s) is, for example, of one of a slit shape, a circular shape, a polygonal shape, and an elliptical shape.

[0013] In an embodiment, the pocket(s) of the net is configured to direct the sporting projectile towards the bottom opening of the pocket after the sporting projectile enters the pocket from the top opening of the pocket. The bottom opening of the pocket(s) of the net is disposed proximal to the support surface. The sporting projectile that enters the corresponding pocket is directed to rest on the support surface to prevent snagging of the net. In an embodiment with multiple pockets, the pockets comprise a pair of outer pockets and a center pocket. The outer pockets are configured to receive the sporting projectile thrown thereto during practicing of disc golf drives and approach shots. The center pocket is configured to receive the sporting projectile thrown thereto during practicing of putts. The center pocket and the pair of outer pockets are configured with multiple different dimensions.

[0014] In an embodiment, each of the pockets of the net further comprises a return channel defined between the top opening and the bottom opening of each of the pockets for receiving, retaining, and directing the sporting projectile towards the bottom opening of a corresponding pocket to rest on the support surface, after the sporting projectile enters the corresponding pocket from the top opening of the corresponding pocket, for retrieval and removal of the sporting projectile, thereby precluding sagging of the net due to weight of multiple sporting projectiles piled or stacked within the pockets. [0015] In an embodiment, the portable training apparatus further comprises a pair of wheel assemblies operably coupled to the pair of base supports of the collapsible frame. The wheel assemblies are configured to move, transport, and position the portable training apparatus on the support surface. A locking element is operably coupled to each of the wheel assemblies. The locking element is configured to lock each of the wheel assemblies and brake the movement of the portable training apparatus on the support surface.

DETAILED DESCRIPTION OF THE INVENTION

[0041] FIG. 1 illustrates a front view of an embodiment of a portable training apparatus 100 comprising a collapsible frame 101 and a net 107 with multiple pockets 108 built into the net 107, where each of the pockets 108 comprises a top opening 109a and a bottom opening 109b integrated into the net 107. The collapsible frame 101 of the portable training apparatus 100 comprises a pair of base supports 102 and 103, a pair of vertical poles or rods 104 and 105 corresponding to the pair of base supports 102 and 103, and a horizontal pole 106. The pair of base supports 102 and 103 is configured to rest on a support surface 112, for example, a ground surface. The base supports 102 and 103 support the portable training apparatus 100 on the support surface 112. The vertical poles 104 and 105 of the collapsible frame 101 are secured to mid-sections 102c and 103c of the base supports 102 and 103, respectively, illustrated in FIG. 4A. Furthermore, the vertical poles 104 and 105 project upwards from the base supports 102 and 103, respectively. The horizontal pole 106 of the collapsible frame 101 is disposed generally perpendicular to the pair of vertical poles 104 and 105. The horizontal pole 106 is secured between the mid- sections 102c and 103c of the pair of base supports 102 and 103, respectively. The collapsible frame 101 comprising the pair of base supports 102 and 103, the pair of vertical poles 104 and 105, and the horizontal pole 106, is configured for disassembly and storage when not in use. The collapsible frame 101 illustrated in FIG. 1 is configured for a portable training apparatus 100 of size, for example, 22 feet wide x 10 feet high. In an embodiment, the collapsible frame 101 of a first size is reconfigurable into collapsible frames of multiple second sizes smaller than the first size for accommodating nets 107 of different sizes as disclosed in the descriptions of FIG. 5E and FIGS. 6A-6E, thereby allowing interchangeability of setups of the portable training apparatus 100 based on user preferences.

[0042] The net 107 of the portable training apparatus 100 is releasably secured to the pair of vertical poles 104 and 105 and the horizontal pole 106 of the collapsible frame 101. The net 107 is releasably secured to opposing ends 104a, 104b and 105a, 105b of the vertical poles 104 and 105, respectively, using fastening elements, for example, ties or cords 111, as illustrated in FIGS. 5C-5E. That is, four comers 107a, 107c and 107b, 107d of the net 107 are hooked or tied to the ends 104a, 104b and 105a, 105b of the vertical poles 104 and 105, respectively, using fastening elements, for example, ties or cords 111. In an embodiment, the net 107 comprises attachment elements 110a and 110b extending from sides 107f and 107g and a bottom edge 107e of the net 107, respectively, as illustrated in FIGS. 5B-5D. The attachment elements 110a and 110b are used for securing the net 107 to the vertical poles 104 and 105 and the horizontal pole 106 of the collapsible frame 101 as illustrated in FIGS. 5B-5E. The net 107 is secured to the collapsible frame 101 and is configured to arrest motion of a sporting projectile 301, for example, a ball, a golf disc, or another flying disc, as illustrated in FIGS. 3A-3B. The net 107 comprises one or more pockets 108 built into the net 107. For example, the net 107 comprises three pockets 108a, 108b, and 108c built into the net 107 as illustrated in FIG. 1. In other embodiments, the portable training apparatus 100 comprises nets 107 of different types, sizes, and dimensions, comprising a different number and types of pockets 108a, 108b, and 108c as illustrated in FIGS. 6A-6E. The nets 107 are configured to be compatible with the collapsible frame 101. In an embodiment, the pockets 108 comprise a pair of outer pockets 108a and 108c and a center pocket 108b. The outer pockets 108a and 108c are configured to receive a sporting projectile 301 thrown thereto during practicing of disc golf drives and approach shots. The center pocket 108b is configured to receive the sporting projectile 301 thrown thereto during practicing of putts. The center pocket 108b and the pair of outer pockets 108a and 108c are configured with multiple different dimensions. The pockets 108a, 108b, and 108c are configured to retain the sporting projectile 301.

[0043] In an embodiment as illustrated in FIG. 1, each of the pockets 108a, 108b, and 108c comprises a top opening 109a and a bottom opening 109b integrated into the net 107. The top opening 109a of each of the pockets 108a, 108b, and 108c is configured as a target to receive the sporting projectile 301. The bottom opening 109b of each of the pockets 108a, 108b, and 108c is configured to allow easy retrieval and removal of the sporting projectile 301. In an embodiment, the top opening 109a of each of the pockets 108a, 108b, and 108c is substantially larger than the bottom opening 109b of each of the pockets 108a, 108b, and 108c. The top opening 109a of each of the pockets 108a, 108b, and 108c is, for example, of one of a circular shape, a generally rectangular shape, a generally square shape, a polygonal shape, and an elliptical shape. The bottom opening 109b of each of the pockets 108a, 108b, and 108c is, for example, of one of a slit shape, a circular shape, a polygonal shape, and an elliptical shape. In an embodiment, the pockets 108a, 108b, and 108c are configured to direct the sporting projectile 301 towards the bottom opening 109b of a corresponding one of the pockets 108a, 108b, and 108c after the sporting projectile 301 enters the corresponding one of the pockets 108a, 108b, and 108c from the top opening 109a of the corresponding one of the pockets 108a, 108b, and 108c. In an embodiment, the bottom opening 109b of the corresponding one of the pockets 108a, 108b, and 108c is disposed proximal to the support surface 112. The sporting projectile 301 that enters the corresponding one of the pockets 108a, 108b, and 108c is directed to rest on the support surface 112 to prevent snagging of the net 107.

[0044] In an embodiment, each of the pockets 108a, 108b, and 108c of the net 107 further comprises a return channel 109c defined between the top opening 109a and the bottom opening 109b of each of the pockets 108a, 108b, and 108c for receiving, retaining, and directing the sporting projectile 301 towards the bottom opening 109b of a corresponding pocket 108a, 108b, or 108c to rest on the support surface 112, after the sporting projectile 301 enters the corresponding pocket 108a, 108b, or 108c from the top opening 109a of the corresponding pocket 108a, 108b, or 108c, for retrieval and removal of the sporting projectile 301, thereby precluding sagging of the net 107 due to weight of multiple sporting projectiles 301 piled within each of the pockets 108a, 108b, and 108c. The return channel 109c funnels the sporting projectiles 301 and allows the sporting projectiles 301 to be removed out of each of the pockets 108a, 108b, and 108c and returned to a user for subsequent throws.

[0045] The portable training apparatus 100 is configured for training users, for example, players who play flying disc sports such as disc golf, also referred to as disc golfers. The portable training apparatus 100 is used, for example, by disc golfers, for practicing disc golf drives, approach shots, and putts by throwing sporting projectiles 301, for example, flying discs or golf discs towards the target pockets 108 built into the net 107. The net 107 of the portable training apparatus 100, for example, serves as a disc golf driving and approach practice net with target pockets 108. A user may throw the sporting projectile 301 towards any one of the pockets 108a, 108b, and 108c in the net 107. The top openings 109a of the pockets 108a, 108b, and 108c in the net 107 serve as targets configured to catch the sporting projectiles 301. When a user throws the sporting projectile 301 at the top opening 109a of any one of the pockets 108a, 108b, and 108c, the sporting projectile 301 passes through the top opening 109a, travels easily into and through the return channel 109c of the corresponding pocket 108a, 108b, or 108c, and rests on the support surface 112 proximal to the bottom opening 109b of the corresponding pocket 108a, 108b, or 108c. The pockets 108a, 108b, and 108c retain the sporting projectiles 301, until the sporting projectiles 301 are removed by a user. The user may remove the sporting projectiles 301 through the respective bottom openings 109b of the pockets 108a, 108b, and 108c, by merely pulling the pockets 108a, 108b, and 108c upwards, which causes the sporting projectiles 301 to slide or roll out of the respective bottom openings 109b. The bottom opening 109b of each of the pockets 108a, 108b, and 108c, therefore, negates the need for the user to bend and remove the sporting projectiles 301 from the pockets 108a, 108b, and 108c during training. The collapsible frame 101 and the net 107 of the portable training apparatus 100 are configured for storage and transportation in a bag, for example, a fabric bag.

[0046] FIG. 2 illustrates a front view of an embodiment of the portable training apparatus 100 comprising a collapsible frame 101 and a net 107 with a single pocket 108b built into the net 107, where the single pocket 108b comprises a top opening 109a and a bottom opening 109b integrated into the net 107. The collapsible frame 101 illustrated in FIG. 2 is configured for a portable training apparatus 100 of size, for example, 10 feet wide x 10 feet high. As illustrated in FIG. 2, the net 107 is releasably secured to the vertical poles 104 and 105 and the horizontal pole 106 of the collapsible frame 101 as disclosed in the description of FIG. 1. The single pocket 108b is located centrally in the net 107. The single pocket 108b is configured to receive and retain a sporting projectile 301, for example, a disc, a ball, etc., as illustrated in FIGS. 3A-3B. The top opening 109a of the pocket 108b is configured to receive the sporting projectile 301. The bottom opening 109b of the pocket 108b is configured to allow removal of the sporting projectile 301. In an embodiment, the pocket 108b further comprises a return channel 109c defined between the top opening 109a and the bottom opening 109b of the pocket 108b for receiving, retaining, and directing the sporting projectile 301 towards the bottom opening 109b of the pocket 108b to rest on the support surface 112, after the sporting projectile 301 enters the pocket 108b from the top opening 109a of the pocket 108b, for retrieval and removal of the sporting projectile 301, thereby precluding sagging of the net 107 due to weight of multiple sporting projectiles 301 piled within the pocket 108b.

[0047] FIG. 3A illustrates an enlarged view of a pocket 108b built into the net 107 of the portable training apparatus 100 shown in FIG. 1, showing multiple sporting projectiles 301 retained within the pocket 108b, proximal to the bottom opening 109b of the pocket 108b. FIG. 3A illustrates the sporting projectiles 301 resting proximal to the bottom opening 109b of the pocket 108b towards the end of the loose return channel 109c, after going through the top opening 109a and into the return channel 109c of the pocket 108b. The loose return channel 109c funnels the sporting projectiles 301 and makes the sporting projectiles 301 rest on a support surface 112, for example, a ground surface, as illustrated in FIG. 3B, to reduce sagging of the net 107 due to the weight of the sporting projectiles 301. A user may retrieve and remove the sporting projectiles 301 caught within the pocket 108b during various throws, for example, disc golf drives, approach shots, and putts, through the bottom opening 109b of the pocket 108b integrated into the net 107.

[0048] FIG. 3B illustrates a partial side perspective view of the net 107 of the portable training apparatus 100 shown in FIG. 1, showing multiple sporting projectiles 301 funneled by the return channel 109c of a pocket 108b built into the net 107, to rest on a support surface 112, for example, a ground surface, proximal to the bottom opening 109b of the pocket 108b. When a user throws multiple sporting projectiles 301 that hit the target pocket 108b, the return channel 109c, that is configured as a loose netting channel, funnels the received sporting projectiles 301 towards the support surface 112 and makes the received sporting projectiles 301 rest on the support surface 112 as illustrated in FIG. 3B, to preclude the net 107 from sagging due to the weight of the received sporting projectiles 301. The sporting projectiles 301 can be easily retrieved through the bottom opening 109b of the pocket 108b by merely pulling the pocket 108b upwards, which causes the sporting projectiles 301 to slide or roll out of the bottom opening 109b of the pocket 108b. The bottom opening 109b of the pocket 108b, therefore, negates the need for the user to bend and retrieve the sporting projectiles 301 when the sporting projectiles 301 are piled in the pocket 108b. In an embodiment, the pocket 108b does not slack below the bottom opening 109b, thereby allowing the sporting projectiles 301 to easily slide out of the bottom opening 109b.

Similarly, the end 106d of the first pole 106a also comprises a spring-loaded device, for example, a ball plunger, for locking the first pole 106a and the second pole 106b to each other. In the process of connecting the end 106d of the first pole 106a to the end 106e of the second pole 106b, when pressure is applied to the ball 106g of the ball plunger at the end 106d of the first pole 106a, the ball 106g begins to sink down and compress a spring (not shown) that is enclosed within the body of the ball plunger. As pressure begins to release, the built-up force from the spring causes the ball 106g at the end 106d of the first pole 106a to be pushed upwards to its original position, causing the ball 106g to emerge out of the hole 106h in the end 106e of the second pole 106b. Similarly, in the process of connecting the ends 106c and 106f of the first pole 106a and the second pole 106b, respectively, to the horizontal holders 114 of the base supports 102 and 103, respectively, when pressure is applied to the ball 106g of the ball plunger at each of the ends 106c and 106f of the first pole 106a and the second pole 106b, respectively, the ball 106g begins to sink down and compress a spring that is enclosed within the body of the ball plunger. As pressure begins to release, the built-up force from the spring causes the ball 106g at each of the ends 106c and 106f of the first pole 106a and the second pole 106b, respectively, to be pushed upwards to its original position, causing the ball 106g to emerge out of the hole 114a in each of the horizontal holders 114 of the base supports 102 and 103, respectively. In an embodiment, the pair of base supports 102 and 103 are optionally secured to the support surface 112 using multiple U-shaped stakes 116 as illustrated in FIG. 5A.

As illustrated in FIG. 6A, the exemplary instruction list comprises constituent parts of an embodiment of the portable training apparatus 100 with a fabric bag 604. In this embodiment, the constituent parts of the portable training apparatus 100 comprise two base supports 102 and 103, constituent parts 106a, 106b, 601, 602, and 603 of an embodiment of the horizontal pole 106, constituent parts 104c, 105c and 104d, 105d of an embodiment of the vertical poles 104 and 105, four U-shaped stakes 116, and one net 107 with three target pockets 108a, 108b, and 108c. Exemplary dimensions of the parts of the portable training apparatus 100 illustrated in FIG. 6A are as follows. The diameter of each of the base supports 102 and 103 is, for example, about 1.25 inches, and the length of each of the base supports 102 and 103 is, for example, about 36 inches. The diameter of each of the constituent parts 106a, 106b, 601, 602, and 603 of the horizontal pole 106 is, for example, about 1.25 inches. The lengths of the constituent parts 106a, 106b, 601, 602, and 603 of the horizontal pole 106 are, for example, about 38.5 inches, 38.5 inches, 40.5 inches, 40.75 inches, and 38.5 inches, respectively. The diameter of each of the constituent parts 104c, 104d and 105c, 105d of the vertical poles 104 and 105, respectively, is, for example, about 1.25 inches. The length of each of the upper poles 104c and 105c of the vertical poles 104 and 105, respectively, is, for example, about 40 inches. The length of each of the lower poles 104d and 105d of the vertical poles 104 and 105, respectively, is, for example, about 41.5 inches.

[0067] The exemplary instruction list provides instructions on how to assemble the collapsible frame 101 comprising the base supports 102 and 103, the vertical poles 104 and 105, and the horizontal pole 106. FIG. 6A illustrates assembly of an embodiment of the collapsible frame 101 of size, for example, 22 feet (’) wide x 10 feet (’) high. The 22’ wide x 10’ high collapsible frame 101 is configured to be convertible and compatible with multiple nets 107 of different sizes. For example, using specific pieces or poles of the 22’ wide x 10’ high collapsible frame 101, the 22’ wide x 10’ high collapsible frame 101 can be reconfigured to build collapsible frames 101 of different sizes such as a 10’ wide x 10’ high collapsible frame, 10’ wide x7’ high collapsible frame, and a 7’ wide x 7’ high collapsible frame to hold and support nets 107 of corresponding sizes. A user may therefore purchase a 22’ wide xlO’ high collapsible frame 101 with multiple nets 107 of sizes, for example, 22’xlO’, 10’xlO’, 10’x7’, and 7’x7’, and interchange their setup according to their training preferences. Similarly, the collapsible frame 101 of each size can be reconfigured to create collapsible frames of sizes smaller than itself as disclosed above. For example, a 10’ wide x 10’ high collapsible frame cannot build a 22’ wide xlO’ high collapsible frame, but can build each collapsible frame smaller than itself apart from its own complete 10’ wide x 10’ high collapsible frame. That is, pieces or poles of the 10’ wide x 10’ high collapsible frame can build collapsible frames of sizes, for example, 10’xlO’, 10’x7’, and 7’x7’ to hold nets 107 of sizes 10’xlO’, 10’x7’, and 7’x7’, respectively.

In the embodiment of the portable training apparatus 100 illustrated in FIG. 6E, the net 107 comprises two target pockets 108a and 108c for catching and retaining sporting projectiles, for example, golf discs, thrown thereto. Each of the pockets 108a and 108c comprises a top opening 109a of, for example, a generally square shape, and a bottom opening 109b of, for example, a generally rectangular shape, for receiving and allowing removal of the sporting projectiles, respectively. Each of the pockets 108a and 108c further comprises a return channel 109c for directing the received sporting projectiles towards the bottom opening 109b of a corresponding pocket 108a or 108c to rest on the support surface, thereby precluding sagging of the net 107 due to weight of the sporting projectiles piled within the corresponding pocket 108a or 108c. The exemplary instruction list further instructs the user to secure the comers 107a, 107c, 107b, and 107d of the net 107 to the ends 104a, 104b and 105a, 105b of the vertical poles 104 and 105, respectively, using fastening elements, for example, ties or cords 111, as illustrated in FIG. 1.

As illustrated in FIG. 9A, to extend the telescopic assembly 901, the telescopic poles 901b and 901d are extended in an outward direction from the opposing ends 901f and 901g of the central telescopic pole 901c, respectively, thereby allowing an increase of the width of the horizontal pole 106 as disclosed in the description of FIG. 10A. Similarly, as illustrated in FIG. 9B, to extend the telescopic assembly 901, the telescopic poles 901b and 901d are partially extended in an outward direction from the opposing ends 901f and 901g of the central telescopic pole 901c, respectively, and the telescopic poles 901a and 901e are fully extended in an outward direction from the telescopic poles 901b and 901d, respectively, thereby allowing an increase of the width of the horizontal pole 106. In an embodiment, when a desired width is achieved, the corresponding telescopic poles are locked in position.

A user may extend the telescopic assembly 901 as illustrated in FIG. 10A, and then connect the opposing ends 901h and 901i of the telescopic assembly 901 to the ends 106d and 106e of the distal, angled or generally V-shaped poles 106a and 106b, respectively. In an embodiment, the ends 106d and 106e of the distal, angled or generally V-shaped poles 106a and 106b, respectively, comprise holes 106h configured to receive and engage the balls 106g of the ball plungers configured at the opposing ends 901h and 901i of the telescopic assembly 901. As illustrated in FIG. 10A, the vertical poles 104 and 105 are extended to their maximum height, and the horizontal pole 106 is extended to its maximum width using the telescopic assembly 901, to accommodate a net 107 of a predetermined size as illustrated in FIG. 1.

In an embodiment, the portable training apparatus 100 further comprises a pair of wheel assemblies 1101, for example, wear-resistant casters made of metal or a plastic material such as high-density polyethylene (HDPE). The wheel assemblies 1101 are operably coupled to the pair of base supports 102 and 103 of the collapsible frame 101. In an embodiment as illustrated in FIG. 11, the wheel assemblies 1101 are operably coupled to the opposing ends 102a, 102b and 103a, 103b of the base supports 102 and 103, respectively. In another embodiment (not shown), one wheel assembly 1101 is operably coupled to each of the mid-sections 102c and 103c of the base supports 102 and 103, respectively. The wheel assemblies 1101 are configured to move, transport, and position the portable training apparatus 100 on a support surface. A locking element 1102 is operably coupled to each of the wheel assemblies 1101. The locking element 1102 is configured to lock each of the wheel assemblies 1101 and brake the movement of the portable training apparatus 100 on the support surface. The locking element 1102 stabilizes the base supports 102 and 103 on the support surface and precludes the collapsible frame 101 from tipping when the collapsible frame 101 is in a substantially vertical, upright position. The wheel diameter, load rating, material, tread width, and overall height of the wheel assemblies 1101 are configurable to provide optimal mobility to the portable training apparatus 100 in different environments.

[0092] FIG. 12 illustrates a front view of an embodiment of the portable training apparatus 100, showing the wheel assemblies 1101 operably coupled to the base supports 102 and 103 of the collapsible frame 101.

[0093] FIG. 13 illustrates a front view of a prophetic embodiment of the portable training apparatus 100, showing multiple sensors 1301 operably coupled to multiple predetermined locations of the net 107 and communicatively coupled to an electronic device 1302. The predetermined locations comprise, for example, the top opening 109a and the bottom opening 109b of each of the pockets 108a, 108b, and 108c of the net 107, a periphery 107h of the net 107, and in and/or around the pockets 108a, 108b, and 108c of the net 107. The sensors 1301 comprise, for example, Hall effect sensors, impact sensors such as piezoelectric film sensors, inertial sensors such as shock sensors, motion sensors, proximity sensors, force and pressure sensors, accelerometers, angular velocity sensors also referred to as gyro sensors, displacement sensors, vibration sensors, location sensors such as global positioning system (GPS) sensors or GPS-enabled sensors, sound sensors, and other sensors configured to detect motion, impacts, vibrations, speed, velocity, location, sound, etc. The sensors 1301 are configured to detect an impact of a sporting projectile 301 illustrated in FIGS. 3A-3B, on an impact location of the net 107, for example, from force and/or displacement, and measure a distance between the impact location and the top opening 109a of each of the pockets 108a, 108b, and 108c of the net 107. As used herein, “impact location” refers to a location on the net 107 where an impact of the sporting projectile 301 on the net 107 occurs. The sensors 1301 operably coupled to the top opening 109a of each of the pockets 108a, 108b, and 108c of the net 107 determine specific angles, paths, and trajectories of throws that reach the targeted pockets 108a, 108b, and 108c or throws that miss the targeted pockets 108a, 108b, and 108c. In an embodiment, one or more of the sensors 1301 also detect and measure sound within a predetermined decibel range to determine whether the sporting projectile 301 impacted the net 107. In an embodiment, one or more of the sensors 1301 comprise counters configured to count the number of throws that resulted in reaching or missing the pockets 108a, 108b, and 108c of the net 107. In an embodiment, the sensors 1301 are configured to communicate with sensor modules (not shown) implemented in the sporting projectile 301, to measure and generate additional performance-based sensor data, for example, rotational velocity of the sporting projectile 301 and other data for determining a flight coefficient of the sporting projectile 301, a user’s grip patterns on the sporting projectile 301, etc. In an embodiment, the sensors 1301 are configured with Internet of Things (loT) technology for transmitting real-time sensor data to the electronic device 1302 via a network.

[0094] In an embodiment, the portable training apparatus 100 further comprises a mobile application 1303 deployed on an electronic device 1302, in operable communication with the sensors 1301 on the net 107. The electronic device 1302 is, for example, one or more of a tablet computing device, a mobile computer, a mobile phone, a smart phone, a portable computing device, a laptop, a personal digital assistant, a wearable computing device such as smart glasses, smart watches, etc., a touch-centric device, a client device, a network- enabled computing device, an interactive network-enabled communication device, a gaming device, an image capture device, a portable media player, a video recorder, an audio recorder, a global positioning system (GPS) device, etc. In an embodiment, the sensors 1301 on the net 107 communicate with the electronic device 1302 via a network, for example, the internet, satellite internet, an intranet, a wired network, a wireless network, a communication network that implements Bluetooth® of Bluetooth Sig, Inc., a network that implements Wi-Fi® of Wi-Fi Alliance Corporation, an ultra-wideband (UWB) communication network, a wireless universal serial bus (USB) communication network, a communication network that implements ZigBee® of ZigBee Alliance Corporation, a general packet radio service (GPRS) network, a mobile telecommunication network such as a global system for mobile (GSM) communications network, a code division multiple access (CDMA) network, a third generation (3G) mobile communication network, a fourth generation (4G) mobile communication network, a fifth generation (5G) mobile communication network, a long-term evolution (LTE) mobile communication network, a public telephone network, etc., a local area network, a wide area network, an internet connection network, an infrared communication network, etc., or a network formed from any combination of these networks. In an embodiment, each of the sensors 1301 comprises a network interface, for example, a Bluetooth® interface, a wireless network interface such as a Wi-Fi® interface, a cellular network interface, a near field communication (NFC) interface etc., configured to connect to or be paired with the electronic device 1302.

[0095] The mobile application 1303 is configured to receive and analyze sensor data associated with the detected impact from the sensors 1301; generate analytics results from the analyzed sensor data to assist in determining performance of a user throwing the sporting projectiles 301; and generate recommendations based on the analytics results to assist in training the user. In an embodiment, the mobile application 1303 communicates with a computer system, for example, a server or a network of servers, via a network, for performing the analysis and analytical processing functions disclosed above. The analytics results provide intricate details of the user’s performance thereby allowing users to review their performance and improve their throws. The analytics results comprise, for example, data, statistics, and analytics about the impact between the sporting projectile 301 and the net 107, distance of the impact location with respect to the target pockets 108a, 108b, and 108c of the net 107, distance of the impact location with respect to the top opening 109a of each of the target pockets 108a, 108b, and 108c of the net 107, etc. In an embodiment, the analytics results are used for reconfiguring the sensors 1301 on the net 107.

[0096] Consider an example where the electronic device 1302 receives sensor data comprising vibrations detected by one or more of the sensors 1301 on the net 107. The mobile application 1303 deployed on the electronic device 1302 analyzes the received sensor data to generate analytics and statistics regarding the impacts between the sporting projectile 301 and the net 107. In an embodiment, the mobile application 1303 generates a score for each throw based on a level of vibration detected by one or more of the sensors 1301. A throw that reaches the top opening 109a of a target pocket, for example, 108b, is determined to be a clean throw that produces substantially low vibrations. The mobile application 1303 generates a high score on analyzing a clean throw within a range of frequencies detected by one or more of the sensors 1301. Similarly, a throw resulting in substantially high vibrations, is not considered a clean throw. The mobile application 1303 generates a low score on analyzing a non-clean throw within another range of frequencies detected by one or more of the sensors 1301. In an embodiment, the mobile application 1303 generates an audible notification to a user, for example, through an audio output device of the electronic device 1302, on determining a clean throw. The mobile application 1303 generates different intermediate scores for throws resulting in vibrations within multiple intervals between high and low levels of vibrations based on their levels of vibrations.

[0097] In an embodiment, the mobile application 1303 further analyzes the sensor data to determine a throw path, a throw angle, and/or throw velocity of a sporting projectile 301, and the timing of the impact between the sporting projectile 301 and the net 107. The mobile application 1303 also generates recommendations comprising, for example, guidance, training feedback, insights, and/or instructions for making adjustments to improve the user’s throwing pattern and/or style based on the analytics results. In an embodiment, the mobile application 1303 generates recommendations based on delta values related to changes in the user's performance. In an embodiment, the mobile application 1303 is configured to calibrate the sensors 1301 for adjusting thresholds, ranges for vibration levels, etc. The mobile application 1303 stores the analytics results in a database (not shown) locally and/or remotely on a server or a network of servers via a network.

[0098] In a prophetic embodiment, the sensors 1301 on the net 107 are configured to communicate with a virtual reality (VR) device 1304, for example, a VR headset, via a network, for example, a Bluetooth® network. The VR device 1304 is configured to display images of a real-world location to the user to create an immersive experience. The VR device 1304 creates a simulation and practice and/or game conditions. The VR device 1304, in communication with the sensors 1301, is configured to control the intensity of the simulation, enabling users, for example, disc golfers, to train with the same level of intensity and pressure as a real game. The images of the real-world location comprise, for example, a disc golf course, a disc golf field, a practice facility, and/or any other real-world locations selected by the user. The portable training apparatus 100, in communication with the VR device 1304, provides training in an immersive environment, thereby allowing the user to practice a variety of different throws, for example, drives, approach shots, putts, etc., in addition to training the user to adjust for different possibilities and attempts to throw the sporting projectile 301 at the target pockets 108a, 108b, and 108c of the net 107.

[0099] The portable training apparatus 100 operates as a training tool that allows users, for example, disc golfers, to perform a high number of repetitions (reps) of throws in a short period of time, while also fine tuning their accuracy in all their throws. The net 107, being substantially large, allows users to stand a long distance away from the net 107 and focus on where they are throwing, instead of performing repetitions of throws merely in front of the net 107. The portable training apparatus 100 allows users to train in flying disc sports, for example, disc golf and other sports, in the convenience of their own back yards. The training imparted by the portable training apparatus 100 allows a user to gain increased knowledge of their targets, allows the user to prepare for throws in any position, and also allows the user to learn proper contact, form, throw path, and/or throw angle for hitting the target pockets 108a, 108b, and 108c of the net 107.

[00100] After hitting the target pockets 108a, 108b, and 108c of the net 107, to preclude bundling up of sporting projectiles 301, thrown when a user performs multiple repetitions of throws, within the pockets 108a, 108b, and 108c behind the net 107, resulting in sagging of the net 107, the return channel 109c defined between the top opening 109a and the bottom opening 109b of each of the pockets 108a, 108b, and 108c funnels the sporting projectiles 301 to rest on the support surface 112, so that the net 107 remains in its original condition without sagging and the user can train at one level each time, providing more consistency in a practice game. The collapsible frame 101 operates as a universal base compatible, for example, for a 22’ wide x 22’ high net, a 10’ wide x 10’ high net, a 10’ wide x 7’ high net, and other nets of different sizes. The collapsible frame 101 can be easily dissembled into constituent poles or parts, and along with the base supports 102 and 103 and the net 107, can be easily stored in a portable carry bag, for example, a fabric bag.

[00101] In addition to practicing putts by throwing the sporting projectiles 301, for example, golf discs, into the center pocket 108b of the net 107, the portable training apparatus 100 also allows users to practice other shots or throws, for example, drives and approach shots, in their back yard or on the go, without having to travel to a disc golf course for disc golf training and practice. Moreover, as the net 107 is configured with target pockets 108a, 108b, and 108c that retain the discs therewithin, the portable training apparatus 100 optimizes training sessions by reducing time it would take to find and retrieve the discs in an open field, thereby allowing users to throw many more shots in a shorter amount of time and maximizing training sessions.
