BACKGROUND

1. Technical Field

The present disclosure relates generally to a net system, and more specifically, to a net system comprising a plurality of detachably connectable net modules having net segments retractable into respective housings.

2. Description of the Related Art

Games involving balls or other projectiles are very common. In many games, the ball or projectile is played on a court or playing surface having a net or barrier over which the projectile is propelled. Exemplary games may include volleyball, tennis, table tennis, badminton, or the like, wherein a ball, shuttlecock, or other projectile is launched/volleyed over the nets. Such games provide enjoyment to individuals of all ages.
In most of the above-mentioned games, the net is erected to divide the playing surface into two areas which are “defended” by opposing teams. The net is generally supported by two support poles which are secured to the ground in spaced relation to each other. Along these lines, many public locations, such as beaches, parks, schools, etc. include dedicated areas for playing such games, wherein support poles are permanently secured to the ground. For instance, it is common for a beach to include volleyball poles properly positioned to allow a user to attach his net thereto for playing beach volleyball. Likewise, public tennis courts commonly include support poles and a tennis net connected to the support poles in an erected position for users to enjoy.
In addition to the foregoing net/barrier games, another common pastime is the game of Four Square, which is typically played on a playing surface without a barrier. The game is commonly played with a resilient/bouncy ball on a solid ground surface, such as concrete or asphalt. Boundaries for the playing surface are marked on the ground to define a large square that is equally divided into four smaller squares. To begin play, players typically enter the large square and each individual player stands in one of the four interior play areas. The ball is served to begin a rally by hitting the ball by hand into any one of the other boxes. More specifically, once the ball is served, the ball enters one of the other internal play zones. The ball is allowed to bounce once, and then the player in that box must strike the ball such that it may bounce within another interior box before the ball bounces again. The rally continues by players striking and returning the ball to other internal play boxes until a player is unable to successfully return the ball to bounce within another player's box.
One of the deficiencies of conventional net/barrier games is that the associated net/barrier apparatus may be difficult to assemble and then subsequently take down and store. Accordingly, various aspects of the present disclosure address this particular need, as will be discussed in more detail below.

BRIEF SUMMARY

In accordance with one embodiment of the present disclosure, there is provided a net system comprising a first net module including a first spool, a first net, and a first connector connected to the first net, with the first net being retractably connected to the first spool such that the first net defines an extended length as a distance between the first spool and the first connector.

DETAILED DESCRIPTION

The detailed description set forth below in connection with the appended drawings is intended as a description of certain embodiments of a retractable sports net and is not intended to represent the only forms that may be developed or utilized. The description sets forth the various structure and/or functions in connection with the illustrated embodiments, but it is to be understood, however, that the same or equivalent structure and/or functions may be accomplished by different embodiments that are also intended to be encompassed within the scope of the present disclosure. It is further understood that the use of relational terms such as first and second, and the like are used solely to distinguish one entity from another without necessarily requiring or implying any actual such relationship or order between such entities.
Referring now to the drawings wherein the showings are for purposes of illustrating a preferred embodiment of the present disclosure, and are not for purposes of limiting the same, there is depicted a selectively deployable sports net apparatus 10 having a plurality of interconnected net segments 12. Each net segment 12 is attached to a connector 14 which may connect with at least one corresponding connector 14 of an adjacent net segment 12. In this regard, several different combinations of net segments 12 may be interconnected to divide a playing court into a number of different playing zones. For instance, two net segments 12 may be interconnected to divide the playing court into two zones. Three net segments 12 may be interconnected to divide the playing court into three zones. Four net segments 12 may be interconnected to divide the playing court into four zones, and so forth.
Each net segment 12 may be retractably connected to a spool located within a respective housing 16, such that when the net segment 12 is not in use, the net segment 12 may be retracted within the housing 14. However, the net segment 12 may be extended out of the housing 14 to deploy the net segment 12 for use. Thus, the ability to extend and retract the net segments 12 relative to the housing 16 may allow for quick and easy setup and take down of the net apparatus 10. Furthermore, the ability to retract the net segment 12 within the housing 16 may allow for convenient storage thereof. By retracting the net segment 12 within the housing 16, the net segment 12 is less likely to snag or become entangled on nearby objects, such as when stored in a garage or the trunk of a vehicle.
FIGS. 1 and 2 depict a net apparatus 10 having four net modules 18 that may be interconnected to each other over a playing court to divide the playing court into equal quarters. Each module 18 may include a housing 16, a net segment 12, and a connector 14. FIG. 1 shows the four net modules 18 connected via their deployed net segments 12, while FIG. 2 shows the four net modules 18 disconnected with each net segment 12 having been retracted in a respective housing 16.
According to one embodiment, the net apparatus 10 includes a base module 18 a and three auxiliary modules 18 b. FIG. 3 shows a base module 18 a in a retracted state, while FIG. 4 shows an auxiliary module 18 b in a retracted state. The primary distinction between the base module 18 a and the auxiliary modules 18 b relates to the respective connectors 14. In particular, the base module 18 a includes a base connector 14 a, while the auxiliary module 18 b includes an auxiliary connector 14 b. As will be explained in more detail below, the base connector 14 a may be configured to connect with several auxiliary connectors 14 b, while each auxiliary connector 14 b may be configured to engage with a base connector 14 a. In other words, the base connector 14 a may not engage with another base connector 14 a, and the auxiliary connectors 14 b may not engage directly with other auxiliary connectors 14 b.
Each housing 16 may include a top wall 20 and a sidewall 22 extending from the top wall 20 to define an interior cavity. The sidewall 22 may include a slit 24 formed therein, which may extend axially along a length of the housing 16. The slit 24 may be in communication with the interior cavity to allow for passage of the net segment 12 therethrough as the net segment 12 is transitioned between extended and retracted configurations. In one embodiment, the housing 16 defines a central axis 26 about which the top wall 20 and sidewall 22 are disposed. The slit 24 formed in the sidewall 24 may extend longitudinally in a generally parallel direction relative to the central axis 26, and generally perpendicular to the top wall 20.
Inside of each housing 16, there may be included a retraction mechanism which may be connected to the corresponding net segment 12. For instance, the retraction mechanism may include a spool 37 that is connected to a spring, which urges the spool 37 to rotate in a first direction, e.g., a direction of retraction. The net segment 12 may be connected to the spool 37, such that when the net segment 12 is in the retracted position, the net segment 12 is wound around the spool 37. Transitioning the net segment 12 from the retracted position toward the extended position may cause a portion of the net segment 12 to unwind from the spool 37 and extend out of the slit 24. In this regard, the interconnection between the spring and the spool 37 may allow for rotation of the spool 37 in a second direction, e.g., a direction of extension, when the net segment 12 is pulled out of the housing 16 by a force having a magnitude that overcomes the biasing force. The biasing force on imparted on the net segment 12 by the retraction mechanism may keep the net segment 12 taut during use. As such, an undesirable saggy net may be mitigated by the retraction mechanism.
The retraction mechanism may be operatively associated with a locking mechanism 27 which may lock the retraction mechanism in place to avoid undesired retraction (or possible extension) of the net segment 12. Referring now to FIGS. 4A and 4B, one embodiment of the locking mechanism 27 includes a hand dial 29 that may be turned relative to the housing 16 to either lock or unlock the locking mechanism 27. The hand dial 29 may include a cylindrical wall that includes inner teeth or serrations 31 that are engageable with outer teeth or serrations 33 formed on a gear 35 attached to the spool 37. The hand dial 29 may be selectively positionable relative to the gear 35 to bring the inner serrations 31 into engagement or out of engagement with the outer serrations 33. When the inner serrations 31 on the hand dial 29 are engaged with the outer serrations 33 of the gear 35, the locking mechanism 27 is locked and the spool 37 may be prevented from rotating. Conversely, when the inner serrations 31 of the hand dial 29 are disengaged from the outer serrations 33 of the gear 35, the locking mechanism 27 may be unlocked and the spool 37 may freely rotate. The hand dial 29 may be moveable along the central axis 26 (e.g., in an upward and downward motion when viewed from the perspective shown in FIG. 4A) to facilitate the selective engagement or disengagement. A spring may be operatively connected to the hand dial 29 to bias the hand dial 29 into the disengaged position, such that a user may be required to press on the hand dial 29 to move that hand dial 29 toward engagement with the gear 35. It is also contemplated that the hand dial 29 may be twisted when pressed downwardly to bring the inner serrations 31 into engagement with the outer serrations 33.
Although the foregoing describes the locking mechanism 27 as including the hand dial 29 and gear 35, other configurations of the locking mechanism 27 may also be used without departing from the sprit and scope of the present disclosure. For instance, the locking mechanism may include a ratcheting gear connected to the spool, and a pawl that interfaces with the ratcheting gear. The configuration of the ratcheting gear and pawl may be such as to allow for generally unrestricted rotation of the spool in the direction of extension, while preventing undesirable rotation of the spool in the direction of retraction. The pawl may be moveable to a disengaged position relative to the ratcheting gear to allow for rotation in the first direction. Transition of the pawl from an engaged configuration to the disengaged configuration may be facilitated by a manually actuated lever, switch, button, etc., operatively coupled to the pawl, or via movement of the net segment 12. For instance, extension of the net segment 12 into a hyper-extended position may release the pawl from the ratcheting gear.
The net segment 12 may be retracted into its respective housing 16 when the external force (e.g., the pulling force) applied to the net segment 12 in opposition to the retraction force may be decreased or removed entirely, e.g., if the user releases the net segment 12, the biasing force causes the spool 37 to rotate in a direction which causes retraction of the net segment 12 around the spool 37.
Referring again specifically to FIGS. 3 and 4, there is depicted an exemplary embodiment of the base connector 14 a, and auxiliary connector 14 b, respectively. The base connector 14 a may include a hollow cylindrical body having a plurality of openings 28 formed therein. Each opening 28 may extend from an outer surface to an inner surface and may be generally elongate in shape. The openings 28 may be arranged in vertical or longitudinal arrays or groupings, with the openings 28 of a given array being aligned along a common axis. Each array may accommodate attachment with a corresponding auxiliary connector 14 b. Thus, by forming multiple arrays of openings 28 on a single base connector 14 a, attachment to multiple auxiliary connectors 14 b may be facilitated. In the exemplary embodiment, each array includes five openings 28 at similar axial locations on the base connector 14 a. In this regard, from the perspective shown in FIG. 3, a bottommost opening 28 for each array is centered at a first circumferential height, an adjacent opening 28 in each array is centered at a second circumferential height, and so forth. The base connector 14 a shown in FIG. 3 includes three sets of arrays, spaced at 90 degrees, 180 degrees, and 270 degrees from the base net segment 12, which may accommodate a four-sided net apparatus 10 with net segments 12 at ninety-degree angles to each other. However, any number of arrays may be included on the base connector 14 a without departing from the spirit and scope of the present disclosure. For instance, the base connector 14 a may include two (2) arrays spaced at 120 degrees and 240 degrees relative to the base net segment 12, which may accommodate a three-sided net apparatus 10 with net segments 12 at 120 degree angles to each other. It is also contemplated that the base connector 14 a may include several arrays to accommodate a number of different net apparatus 10 configurations. For instance, the base connector 14 a may be configured to accommodate a net apparatus 10 including two net segments 12, three net segments 12, four net segments 12, etc. In this regard, the base connector 14 a may include arrays at 90 degrees, 120 degrees, 180 degrees, 240 degrees and 270 degrees relative to the base net segment 12. The 90, 180, and 270 degree arrays may be intended for a 4-sided configuration, while the 120 and 240 degree arrays may be intended for a 3-sided configuration. However, it is understood that auxiliary net segments 12 may be connected to any array, and thus, if a user wanted to create unequal playing zones, the auxiliary net segments 12 may be connected to unequally spaced arrays.
The auxiliary connector(s) 14 b may be complementary to the base connector 14 a to facilitate detachable engagement therewith. In the exemplary embodiment, the auxiliary connector 14 a includes a series of hooks 30 that may be received within a given array of openings 28 formed within the base connector 14 a. The hooks 30 may include a finger that may extend within the hollow interior of the base connector 14 a when the auxiliary connector 14 b is engaged with the base connector 14 a. The number of hooks 30 included on a given auxiliary connector 14 b may be identical to the number of openings 28 in a given array on the base connector 14 a.
Although the embodiment depicted in FIGS. 3 and 4 includes openings 28 formed on the base connector 14 a and hooks 30 formed on the auxiliary connector 14 b, it is contemplated that other embodiments may include a reverse configuration, e.g., with the base connector 14 a including hooks 30 and the auxiliary connector 14 b including openings 28. Moreover, it is contemplated that other mechanical connectors known by those skilled in the art may also be used to connect the base connector 14 a to the auxiliary connector 14 b. For instance, hook and loop fasteners (e.g., VELCRO™), magnets, snaps, tongue and groove connectors may also be used. FIG. 5 depicts an alternative embodiment showing an example of hook and loop fasteners used to connect adjacent net segments together. In particular, the base connector 14 a includes a cylindrical outer surface covered with hook and loop material, and the auxiliary connector 14 b may include one or more strips of complementary hook and loop material engageable with the base connector 14 a to facilitate connection with the base connector 14 a.
Each housing 16 may be connected to a support pole 32 to elevate the net segment 12 above the court or playing surface. The support pole 32 may be detachably engageable to the housing 16, such as via threaded engagement, a removeable pin, or other detachable engagement mechanisms known in the art. However, it is also contemplated that the support pole 32 may be mounted more permanently to the housing 16, such as via an adhesive. Each support pole 32 may include an enlarged foot 34 to enhance stability of the net apparatus 10.
With the basic structure of the net apparatus 10 having been described above, the following discussion pertains to an exemplary use of the net apparatus 10. To set up the net apparatus 10, a user obtains the desired number of net modules 18 for the net apparatus 10. For instance, if a four-sided net apparatus 10 is desired, the user should obtain four net modules 18, including one base module 18 a and three auxiliary modules 18 b.
Once the required/desired number of net modules 18 are obtained, the user extends the net segment 12 of the base module 18 a and the net segment 12 of at least one auxiliary module 18 b. To extend the net segments 12, the user may pull on the base connector 14 a and auxiliary connector 14 b, respectively, or any portion of the net segment 12 that may be extending out of the housing 16 to increase the distance between the connector 14 and is respective housing 16. The extended net segments 12 may be engaged by advancing the hooks 30 on the auxiliary connector 14 b through respective openings 28 formed on the base connector 14 a. The user may connect any remaining auxiliary net module 18 b to the base module 18 a by extending the net segments 12 and engaging the auxiliary connector(s) 14 b to the base connector 14 a.
Although the foregoing describes extending the net segments 12 prior to engaging the connectors 14, it is understood that the opposite sequence may occur. In particular, the connectors 14 may be engaged, and then the net segments 12 may be extended.
With the net segments 12 extended and the connectors 14 engaged, the user may position the net apparatus 10 over the playing surface, with the support poles 32 being placed at the periphery of the playing surface. The net apparatus 10 may be configured such that the net apparatus 10 may remain elevated above the playing surface with no center support pole. In this regard, there may be no support pole extending along a central axis, from which the net segments radiate. In other words, there may be no support pole directly connected to the base connector 14 a and/or auxiliary connector(s) 14 b.
When the net apparatus 10 is assembled, the net apparatus 10 may be used to play a game combining the features of conventional volleyball and four square, as explained in U.S. Pat. No. 9,504,892, entitled Game Apparatus and Method of Playing the Same, the contents of which are expressly incorporated herein by reference.
To disassemble the net apparatus 10, the net segments 12 are retracted and the auxiliary connectors 14 b are disconnected from the base connector 14 a. When the net segments 12 are retracted, each connector 14 may be moved closer to its corresponding housing and the net segments 12 may be wound around the spool 37 or axle located within the housing 16 to mitigate tangling of the net segments 12. It is contemplated that the auxiliary connectors 14 b may be disconnected from the base connector 14 a prior to retraction of the corresponding auxiliary net segment 12 into the housing 16. Alternatively, the net segments 12 may be retracted and then the auxiliary connectors 14 b may be disengaged from the base connector 14 a.
If the support poles 32 are detachable from the housings 16, the user may detach the support poles 32 to facilitate storage of the net apparatus 10.
When the net apparatus 10 is taken down, the net modules 18 may be easily stored within a vehicle, garage, storage shed, etc., with the net segments 12 entirely or substantially contained within their respective housings 16. Snagging of the net segments 12 on adjacent equipment is mitigated by the containment of the net segments 12 within the housings 16. As such, when the user wants to use the net apparatus 10 again, the net apparatus 10 may remain in an easily deployable and ready to use configuration.
Referring now to FIGS. 8 and 9, there is depicted another embodiment of an auxiliary module 118 b (see FIG. 8) and a base module 118 a (see FIG. 9), wherein the modules 118 a, 118 b are specifically configured or adapted such that the net segment 112 of each module 118 a, 118 b may be at least partially exposed or uncovered when the net segment 112 is in the retracted configuration. In this regard, it is contemplated that the modules 118 a, 118 b may be formed without a housing, or alternatively, a very minimal housing.
In the embodiment depicted in FIG. 8, the auxiliary module 118 b includes an upper body 119 b, a lower body 121 b, and a guide strap 123 b extending between the upper body 119 b and the lower body 121 b. The upper and lower bodies 119 b, 121 b depicted in FIG. 8 are cylindrical, although other shapes, such as quandrangular, triangular, etc., are also contemplated. The guide strap 123 may be rigid or flexible and may assist in gathering the net segment 12 as it is retracted. A spool or rod may extend between the upper and lower bodies 119 b, 121 b and may be connected to the net segment 112, which in turn, in connected to the auxiliary connector 114 b. The spool or rod may rotate relative to the upper and lower bodies 119 b, 121 b as the net segment 112 is extended and retracted.
The base module 118 a shown in FIG. 9 is similar, in that it also includes an upper body 119 a, a lower body 121 a, and a guide strap 123 a extending between the upper body 119 a and the lower body 121 a. A spool or rod may extend between the upper and lower bodies 119 a, 121 b and may be connected to the net segment 112, which in turn, in connected to the base connector 114 a. The spool or rod may rotate relative to the upper and lower bodies 119 a, 121 a as the net segment 112 is extended and retracted.
Although the embodiments of the modules 118 a, 118 b, shown in FIGS. 8 and 9 include a guide strap 123 a, b, it is contemplated that other embodiments may be formed without a guide strap 123 a, b or a housing. In this regard, various embodiments may be formed without anything extending between an upper housing, end cap or body, and a corresponding lower housing, end cap or body, except for a central spool around which the net segments 12 may gather as they are retracted.
Referring now to FIG. 10, there is depicted another embodiment of a net apparatus 210 that includes a center pole 215 connectable to one or more net modules 18 for supporting the net(s) above a playing surface. Each of the net modules 18 included in the net apparatus 210 shown in FIG. 10 are auxiliary net modules 18 b, described in more detail above. The center pole 215 includes a base connector 214 from which a rod or shaft 217 extends. The base connector 214 is similar in configuration to the base connector 14 a described above, particularly in its ability to engage with the auxiliary connectors 14 b on the auxiliary net modules 18 b. The rod or shaft 217 is connectable to the ground to position the base connector 214 at approximately the same height as the auxiliary connectors 14 b on the net modules 18. Alternatively, the shaft 217 may be connected to a foot or base plate which rests on the ground and allows the shaft 217 to extend upwardly from the ground.
The use of the center pole 215 may provide more central support to the net apparatus 210, if so desired. In addition, the center pole 215 may allow for use of the net apparatus 210 without a base net module 18 a. Thus, in the event a base net module 18 a becomes lost or damaged, a center pole 215 may be used to connect multiple auxiliary net modules 18 b. Accordingly, the center pole 215 may provide enhanced structural support, as well as enhanced functional adaptability.
Although the embodiment depicted in FIG. 10 includes rod or shaft 217 extending from the base connector 214 to support the base connector 214 over the ground, it is contemplated that in other embodiments, the base connector 214 may be used without rod or shaft 217 such that when the base connector 214 is attached to at least two net modules 18 b, the base connector 214 may be supported above the ground due to the interconnection to the net modules 18 b. In other words, when the base connector 214 is connected to the net modules 18 b, the tension in the net modules 18 b may support the base connector 214 over the ground without anything extending directly below the base connector 214 (e.g., independent of any additional support structure along a central axis defined by the base connector 214).
It is further contemplated that the rod or shaft 217 may be detachably engaged with the base connector 214 to allow for engagement between the shaft 217 and the base connector 214 when desired, and detachment of the shaft 217 from the base connector 214 when desired. For instance, it may be desirable to have the shaft 217 engaged to the base connector 214 when setting up the net apparatus 210 to ensure the net apparatus 210 is set up centrally over a playing court, and to minimize the number of individuals that may be required to set up the net apparatus 210 (e.g., it may be possible for a single individual to set up the net apparatus 210). However, after the net apparatus 210 has been assembled, the tension in the net modules 18 b may provide sufficient support to the base connector 214, to allow for detachment of the shaft 217 from the base connector 214. Removal of the shaft 217 from the base connector 215 may remove a possible obstruction when playing with the net apparatus 210. The detachable engagement may be facilitated via threaded interconnection between the shaft 217 and the base connector 124, spring detent connection, friction fit, or other mechanical interconnections known by those skilled in the art.
Referring now to FIGS. 11-12, there is depicted another embodiment of a multi-sided net system 300 including a hub 302 specifically configured and adapted to facilitate attachment of one or more net modules 304 to an existing volleyball net 306, badminton net, tennis net, or other planar sports nets known in the art. In this regard, for those users already in possession of an existing sports net 306, the hub 302 may be a useful add-on to enhance the overall utility of the existing sports net 306.
The hub 302 may be generally cylindrical in nature and define a longitudinal axis 308. The hub 302 includes a generally circular upper face 310, an opposing generally circular lower face 312, and an outer sidewall 314 extending between the upper and lower faces 310, 312. The hub 302 additionally comprises a pair of channels 316 extending into the hub 302 (e.g., radially inward) from the sidewall 314 and axially from the upper face 310 toward the lower face 312 in diametrically opposed relation to each other in a direction that is generally parallel to the longitudinal axis 308. Each channel 316 may terminate in spaced relation to the lower face 312 to define a shoulder 318, the importance of which will be described in more detail below. Although the exemplary embodiment includes a pair of channels 316, it is contemplated that in other embodiments, the hub 302 may include a single channel 316 or more than two channels 316, e.g., three, four, five, etc.
The hub 302 additionally includes a slot 320 extending from the lower face 312 toward the upper face 310 along a plane that divides the hub 302 into approximately two equal halves. The slot 320 is sized to receive at least a portion of the existing volleyball net 306 to allow the hub 302 to be slid over the top of the existing volleyball net 306.
The hub 302 is adapted to be used in connection with one or more net modules 304, which may generally include a net segment 322 and a housing 324, as described in more detail above. The net module 304 may additionally include a module connector 326 that is configured to be engageable with the hub 302. In the embodiment shown in FIGS. 11-12, the module connector 326 includes a rib sized to be slidably received in a respective channel 316 formed on the hub 302. Furthermore, the rib 326 may be of a length such that when the rib 326 is completely inserted into the channel 316, it contacts the shoulder 318, which may result in the top of the net segment 322 being generally aligned with the top of the volleyball net 306.
With the basic structure of the hub 302 and net modules 304 having been described, the following discussion relates to an exemplary use thereof. A user may setup the existing volleyball net 306 between a pair of support poles in a conventional manner. Ideally, the volleyball net 306 is taut or stretched to remove slack when attached to the support poles.
After the volleyball net 306 has been set up, the user may place the hub 302 onto the volleyball net 306, preferably at a midsection of volleyball net 306. The hub 302 may be placed on the volleyball net 306 by aligning the net 306 (e.g., the plane of the net) with the slot 320 on the hub 302 and advancing the net 306 through the slot 320 until the hub 302 rests on the net 306. When the hub 302 is connected to the net 306, the channels 316 on the hub 302 may be located on opposite sides of the net 306.
With the volleyball net 306 assembled, and the hub 302 being placed on the volleyball net 306, the user may assemble the net modules 304. In particular, each net module 304 may include a support pole 328 that may be placed in, or on, the ground. The net segment 322 may be extended from its housing 324 and the module connector 326 may be advanced into a respective channel 316 on the hub 302. In particular, the module connector 326 may advanced into the channel 316 until the module connector 326 contacts, or rests against, the shoulder in the channel 316. A biasing element or spring may impart a biasing force on the net segment 322 that may create tension in the net segment 322 to keep the net segment 322 taut when extended between the housing 324 and the hub 302.
When both net segments 322 are connected to the hub 302, a four-sided net assembly 300 may be collectively defined by the existing volleyball net 306, and the pair of net modules 304. In particular, the volleyball net 306 may define two-sides by the portions of the volleyball net 306 extending on opposite sides of the hub 302. The other two-sides may be defined by the net segments 322 of the net modules 324.
To disassemble the net assembly 300, the user removes the module connectors 326 from their respective channels 316, and retracts the net segments 322 into their housings 324. The hub 302 may be removed from the volleyball net 306 and the volleyball net 306 may be taken down.
The particulars shown herein are by way of example only for purposes of illustrative discussion, and are not presented in the cause of providing what is believed to be most useful and readily understood description of the principles and conceptual aspects of the various embodiments of the present disclosure. In this regard, no attempt is made to show any more detail than is necessary for a fundamental understanding of the different features of the various embodiments, the description taken with the drawings making apparent to those skilled in the art how these may be implemented in practice.
