CROSS REFERENCE TO RELATED APPLICATIONS 
     This application claims the benefit and priority of U.S. Provisional Application No. 62/349,568, entitled “Adaptable Net,” filed on Jun. 13, 2016, the entire contents of which are hereby incorporated by reference herein. 
    
    
     BACKGROUND 
     Field 
     The present disclosure relates to a modular net for use with pool equipment and, more particularly, to a modular net having multiple pieces removably coupled together. 
     Description of the Related Art 
     Uncovered swimming pools can undesirably collect debris, such as leaves, insects and dirt, from the environment. Pool owners may use various types of nets, called pool rakes or pool skimmers, to remove such debris from swimming pools. The different types of nets may each be advantageous in different situations. For example, pool rakes may have a deeper net and may be best suited for collecting debris from a bottom of the pool. Pool skimmers, on the other hand, may have a shallower net and may be best suited for collecting debris from a top of the pool. 
     With the advent of online shopping, individuals are purchasing more and more items from the Internet. Such items are typically stored in a warehouse and then shipped to the customer upon receipt of the order. The cost of shipping an item may vary based on the size of the item and the weight of the item. Pool nets may be relatively large in size. In that regard, the cost for shipping a pool net may be relatively high. 
     Thus, there is a need for pool nets that may be shipped in relatively small packaging in order to reduce delivery costs. 
     SUMMARY 
     Described herein is an apparatus for collecting debris. The apparatus includes a frame having a connector configured to attach to a pole. The frame includes a plurality of frame rods each designed to be removably connected to at least one other frame rod via a tongue-and-groove feature such that the plurality of frame rods define an opening when connected together. The apparatus further includes a netting designed to be removably connected to the frame and to substantially fill the opening defined by the plurality of frame rods. 
     Also described is an apparatus to be attached to a pole for removing debris from a swimming pool. The apparatus includes at least two frame rods defining an opening therebetween and including a first frame rod and a second frame rod each having a distal end distal to the pole and a proximal end proximal to the pole. The apparatus further includes a first connector adapted to attach the first frame rod and the second frame rod to each other at the proximal end and to attach the first frame rod and the second frame rod to the pole. The apparatus further includes a second connector adapted to attach the first frame rod and the second frame rod to each other at the distal end. The apparatus further includes a netting adapted to be coupled to at least one of the first frame rod or the second frame rod.

     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS 
     Exemplary embodiments of a net will now be described in detail. These embodiments describe various features and functionality of the net. When used herein, the net may refer to any device with a handle and netting used to collect debris, including fishing nets, leaf or pool skimmers, leaf or pool rakes, or the like. 
       FIG. 1  illustrates an embodiment of a net apparatus  100 . The net apparatus  100  includes a first frame rod  102  and a second frame rod  104 . The first frame rod  102  includes a distal end  106  and a proximal end  110 . The second frame rod  104  includes a distal end  108  and a proximal end  112 . A first connector  114  is used to attach the proximal end  110  of the first frame rod  102  to the proximal end  112  of the second frame rod  104 . The first connector  114  also attaches the first and the second frame rods  102 ,  104  to a pole  116 . A second connector  118  is also included that is adapted to attach the distal end  108  of the first frame rod  102  to the distal end  108  of the second frame rod  104 . The second connector  118  may include a hinge  120  that allows the first frame rod  102  to substantially overlay the second frame rod  104  for storage or shipping. 
     The first and the second frame rods  102 ,  104  can be formed from a material such as a metal, plastic, rubber, wood, composite, etc. The frame rods  102 ,  104  can be interchangeable, such that if a user is using plastic frame rods  102 ,  104  and wants to switch to metal frame rods  102 ,  104 , the user may remove the plastic frame rods  102 ,  104  from the net apparatus  100  and replace them with the metal frame rods  102 ,  104 . 
     Interchangeability can provide advantages over the state of the art. First, if one of the frame rods  102 ,  104  breaks, the user may replace the broken frame rod  102 ,  104  instead of the entire net apparatus  100 . Additionally, there may be times when metal frame rods  102 ,  104  are preferable over plastic frame rods  102 ,  104 , and vice versa. For example, if a relatively large amount of debris is present at the bottom of a swimming pool, it may be advantageous to use metal frame rods  102 ,  104 , as metal is denser and will allow the net to approach the bottom of the pool more easily. On the other hand, if a lot of floating debris exists, it may be advantageous to use plastic, as plastic is less dense and will allow for easier surface skimming. 
     The frame rods  102 ,  104  may have any shape. For example, they may include curves, such as those illustrated in  FIG. 1  such that an opening  122  between the frame rods  102 ,  104  has a rounded shape. In some embodiments, the frame rods  102 ,  104  can include angles instead of curves, such that the opening  122  includes an angular shape such as a square, parallelogram, hexagon or the like. In some embodiments, the frame rods  102 ,  104  may include both angles and curves, such that the opening  122  has a combined curved and angular design. In some embodiments, more frame rods may be included than the frame rods  102 ,  104  and all of the frame rods may be straight. In these embodiments, the net apparatus  100  may include additional connectors which are angled or rounded so as to create an angle between the frame rods. 
     The frame rods  102 ,  104  may be solid rods, such as those illustrated in  FIG. 1  or they may be hollow structures. The outer surface of the frame rods may be rounded (such that a cross-sectional view would appear circular, oval or the like) or they may be angled (such that a cross-sectional view would appear square, rectangular, triangular, or the like). 
     The frame rods  102 ,  104  may be adapted such that they can be coupled to a netting  124 . The netting  124  may be attached to the frame rod such that when the frame rods  102 ,  104  are displaced along an axis that extends through the opening  122 , any object that is larger than a hole  126  defined by the netting  124  will be collected by the netting  124 . In other words, when the frame rods  102 ,  104  are displaced along a plane extending through the opening  122 , any object that is smaller than the opening  122  will pass through the plane and into the netting  124 . 
     The netting  124  may be coupled to the frame rods  102 ,  104  in a variety of manners. For example, the netting  124  may include openings along its perimeter such that the openings can slide over and receive the frame rods  102 ,  104 . In some embodiments, the frame rods  102 ,  104  may be threaded through holes  126  of the netting  124  along the perimeter of the netting  124 . 
     In some embodiments, the netting  124  may include a beveled perimeter material having a shape similar to that of the opening  122 . The perimeter may be designed such that it fits over and receives the frame rods  102 ,  104  and locks in place. 
     In some embodiments, the netting  124  may include male or female button portions spaced apart along its perimeter. The frame rods  102 ,  104  may have matching female or male button portions spaced similarly to the button portions on the netting  124 . The button portions may attach and secure the netting  124  to the frame rods  102 ,  104 . Instead of button portions, any connection means may be used, such as any snap connectors including but not limited to those illustrated in  FIG. 2 . 
     In some embodiments, the netting  124  may include rubber around its perimeter. In these embodiments, the rubber may be stretched so that it fits around the frame rods  102 ,  104 . When placed around the frame rods  102 ,  104  the rubber may then contract and hold the netting  124  in place. 
     In some embodiments, the netting  124  may include straps spaced apart along its perimeter such that the straps extend from the netting  124  around the frame rods  102 ,  104  and attach. For example, a strap may include a first portion having a female button portion and a second portion having a male button portion. In this example, the first portion and the second portion can attach to each other around a frame rod  102 ,  104  such that the portions are attached to the frame rod  102 ,  104 . The straps may include hook and loop fasteners, such as Velcro®, instead of or in addition to buttons to form the attachment. 
     The straps may also use snap connectors instead of buttons or hook and loop fasteners in order to attach.  FIG. 2  illustrates exemplary snap connectors which may be utilized between the portions of the straps. 
     In some embodiments, the perimeter of the netting  124  can include extra material having hooks on one side and loops on the other side. In these embodiments, the extra material can wrap around the frame rods  102 ,  104  and attach using the hook and loop fasteners, such that the netting  124  is attached to the frame rods. 
     It will be apparent to one in the art that the netting  124  can be attached to the frame rods  102 ,  104  in any manner and the attachment feature is not limited to the specific attachments discussed herein. 
     The ability to attach and detach the netting  124 , as described herein, is advantageous. Sometimes, only a small amount of debris is present in the pool. In such a situation, a shallower net (i.e., a skimmer) may be preferable to a deeper net (i.e., a pool rake), as the extra netting may be unnecessary and may result in undesirable drag in the water. Occasionally, however, a deep net is preferable, such as when a lot of debris is present in the pool. Situations may also arise where it is preferable to use a net with smaller holes  126 , for example, if a lot of fine debris is present in the pool. Other times it may be preferable to use a netting  124  with larger holes  126 , for example, if the debris is less fine. The ability to attach and detach the netting  124  allows for use of the net apparatus  100  with a netting  124  that is best suited for any given situation. 
     Additionally, if a netting  124  breaks, an entirely new net apparatus is unnecessary because a new netting  124  may be used with the remaining structure of the net apparatus  100 . Because the netting  124  is detachable, a new netting  124  can be purchased, resulting in repair that may be less expensive than replacement. 
     The first connector  114  may be made out of metal, plastic, wood or the like. The first connector  114  may be made of a different type of material than the frame rods  102 ,  104 . 
     The first connector  114  may attach using any means. For example, the first connector may include a socket, such as that illustrated in  FIG. 1 . The shape of the first connector  114  may be a cylindrical tube. 
     The first connector  114  is adapted to couple the first and the second frame rods  102 ,  104  to each other. The first connector  114  can couple the frame rods  102 ,  104  in a variety of manners. For example, the proximal ends  110 ,  112  of the frame rods  102 ,  104  may each include a male portion of a snap connector, such as one illustrated in  FIG. 2 , and the first connector  114  may include a female portion of the snap connector. The proximal ends  110 ,  112  of the frame rods  102 ,  104  may insert into the first connector  114  where they are attached by the snap connector. The connection may remain in place until the snap connector is manually actuated to release the connection. The frame rods  102 ,  104  may be coupled to the first connector such that the first connector  114  holds the frame rods  102 ,  104  in place relative to each other. 
     The first connector  114  may alternately use screws to attach the frame rods  102 ,  104  together. For example, the proximal end  112  of the second frame rod  104  may include female screw threading and the connector  114  may include a hole  130 . The proximal end  112  of the second frame rod  104  may insert into the connector  114  such that the female threading lines up with the hole  130  and a screw is inserted into the connector and attaches the connector to the second frame rod  104 . The first frame rod  102  may also include female threading so that a screw can be inserted into the connector through a hole  128  and screw into the female threading of the proximal end  110  of the first frame rod  102 . 
     The frame rods  102 ,  104  may also attach to the connector  114  using a spring clip. For example, the proximal end  112  of the second frame rod  104  can include a spring clip. When the proximal end  112  of the second frame rod  104  is inserted into the connector  114 , a button of the spring clip may enter into the hole  130 . In this embodiment, the second frame rod  104  may be attached to the connector  114  until the button is pressed through the hole  130  and the second frame rod  104  is removed from the connector  114 . The proximal end  110  of the first frame rod  102  may also include a spring clip that has a button adapted to enter the hole  128 . 
     Alternately, a spring clip may exist within the first connector  114 . In this embodiment, when the frame rods  102 ,  104  are inserted into the first connector  114 , a button of the spring clip may push through a hole in the frame rods  102 ,  104 . This button may then enter the holes  130 ,  128 , locking the frame rods  102 ,  104  in place. When the buttons are depressed through the holes  130 ,  128 , the frame rods  102 ,  104  may be removed. 
     In some embodiments, a hole exists through the proximal ends  110 ,  112  of the frame rods  102 ,  104 . In these embodiments, a pin, such as a spring pin or a split pin, may extend through the holes at the proximal ends  110 ,  112  of the frame rods  102 ,  104  and through the holes  128 ,  130 . The pin may then attach the frame rods  102 ,  104  to the first connector  114 . 
     The first connector  114  is also adapted to attach the frame rods  102 ,  104  to the pole  116 . The first connector  114  may attach to the pole  116  in a variety of manners. For example, the first connector  114  may attach to the pole  116  using screws, snap connectors, spring clips or the like, as described above with reference to the attachment of the frame rods  102 ,  104  to the connector  114 . 
     In some embodiments, the first connector  114  and the pole  116  may each include holes such that they can be attached using a pin. In some embodiments, the pole  116  and the first connector  114  may include threading, such that the pole  116  may screw into the first connector  114  for attachment. In some embodiments, the first connector  114  may define a cavity for receiving the pole. 
     Additionally, the manner in which the first connector  114  is attached to the pole  116  may be different from the manner in which the first connector  114  is attached to the frame rods  102 ,  104 . For example, the pole  116  may attach to the first connector  114  using a snap connector, including but not limited to those illustrated in  FIG. 2 , and the frame rods  102 ,  104  may attach to the connector  114  using spring clips. 
     The ability to connect and disconnect the frame rods  102 ,  104  and the pole  116  from the connector  114  can provide advantages. For example, it allows modularity of frame rods  102 ,  104 . For example, if a user wants to use frame rods  102 ,  104  that form a larger opening  122 , he can simply detach the original frame rods  102 ,  104  and insert larger frame rods  102 ,  104 . 
     Additionally, different connectors  114  may be adapted to attach to different sized poles. A user may be able to switch poles by detaching the frame rods  102 ,  104  from the first connector  114  and attaching them to a connector  114  that is adapted to attach to the new pole. 
     The first connector  114  may also be adapted to attach to poles  116  of different widths. For example,  FIG. 3  illustrates an exemplary net apparatus that uses an adaptable first connector  114 . As illustrated in  FIG. 3 , the first connector  114  may include an adapter  300 . In some embodiments, the adapter  300  is a sleeve that can be positioned over the first connector  114 . In some embodiments, the adapter  300  can attach to the end of the first connector  114 . 
     In some embodiments, the adapter  300  is adapted to attach to a pole  116  of a different diameter than the first connector  114  is adapted to attach to. In some embodiments, the first connector  114  is not adapted to attach to a pole without the adapter  300 . 
     The pole  116  may be adapted to attach to the connector  114  using a first connection means, such as a screw, a snap connector, a spring clip, or the like. Occasionally it may be desirable to swap out the original pole for a pole having a smaller diameter. In such a situation, the adapter  300  may be configured to attach to the pole having the smaller diameter. The adapter  300  may attach to the first connector  114  using the same first connection means. Accordingly, if the pole  116  is adapted to connect to the first connector  114  using a snap connector, then the adapter  300  may connect to the first connector  114  using the snap connector. 
     Because the adapter  300  is adapted to attach to the pole  116  having the smaller diameter, the adapter  300  allows the pole  116  having the smaller diameter to attach to the connector  114 . The adapter  300  may be adapted to attach to the pole  116  using any type of connection, such as screws, snap connectors, spring clips or the like, as described above with reference to the attachment of the pole  116  to the connector  114 . 
     The type of connection between the adapter  300  and the first connector  114  is not required to be the same type of connection as between the adapter  300  and the pole. For example, the adapter  300  may attach to the pole  116  via threading, and the adapter  300  may attach to the connector  114  via snap connectors. 
     This feature provides an advantage of easier portability and storage. For example, for storage purposes, the adapter  300  can remain attached to the pole  116 . Because of the by a relatively minor amount. The adapter  300  may then detach from the first connector  114  such that the net apparatus  100  may be stored separately from the pole  116 , thus requiring less space. Because of the connection type between the adapter  300  and the first connector  114 , the net apparatus  100  can be quickly and easily reattached to the pole  116  for use via the adapter  300  and the first connector  114 . 
     Referring back to  FIG. 1 , use of a hinge as the first connector  114  may allow the first and the second frame rods  102 ,  104  to rotate about each other. For example, the first frame rod  102  may be attached to a first portion of the first connector  114  which may rotate around a center of the first connector  114 . The second frame rod  104  may be attached to a second portion of the first connector  114  which may rotate around the center of the first connector independently from the first frame rod  102 . 
     In some embodiments, the first connector  114  may include a mechanism that allows the rotation of the first and second portion to lock and unlock. This mechanism may be any type of mechanism, such as a latch, a spring clip, a lock-pin, or the like. This may be beneficial because it may be desirable for the frame rods  102 ,  104  to remain in place such that the opening  122  is as large as possible while in use. 
     These embodiments may allow the first and the second frame rods  102 ,  104  to rotate towards each other while still attached to the first connector  114  so that the net apparatus  100  requires less space for storage. This may also result in reduced effort for storage, as the frame rods  102 ,  104  may not require detachment from the first connector  114  in order to reduce in size. As the frame rods  102 ,  104  may already substantially overlay each other and as the first connector  114  only adds negligible bulk to the net apparatus  100 , it may not be necessary for the frame rods  102 ,  104  to be removable from the first connector  114 . 
     In some embodiments, the pole  116  may be permanently affixed to the first connector  114 . In these embodiments, the first and the second frame rods  102 ,  104  may be removably attached to the first connector  114 . For storage, the first and second frame rods  102 ,  104  may be detached from the first connector  114  and the pole  116  may be stored separately with the first connector  114 . 
     The second connector  118  may be made out of metal, plastic, wood or the like. The second connector  118  does not have to be made of the same type of material as the frame rods  102 ,  104  or the first connector  114 . 
     The second connector  118  may be any type of connector. In some embodiments, the second connector  118  may be built onto the frame rods  102 ,  104  (illustrated in  FIG. 5 ). In these embodiments, the frame rods  102 ,  104  may connect directly to each other. 
     In some embodiments, the second connector  118  may attach to the frame rods  102 ,  104 , as illustrated in  FIG. 1 . The second connector  118  may attach to the frame rods  102 ,  104  via threading, any snap connectors, including but not limited to those illustrated in  FIG. 2 , spring clips or the like. 
     The second connector  118  may include a hinge  120 . The hinge  120  may pivotably attach the frame rods  102 ,  104  to each other. In some embodiments, the hinge  120  may be a knuckle joint such as the joint illustrated in  FIG. 1 . In these embodiments, the first frame rod  102  (or the second frame rod  104 ) may include a male hinge portion  132  and the second frame rod  104  (or the first frame rod  102 ) may include a female hinge portion  134 . The male and female hinge portions  132 ,  134  may connect and attach the frame rods  102 ,  104  together. 
     In some embodiments, the male hinge portion  132  may include a protrusion on either side of the outer tip and the female hinge portion  134  may include an indention in the inside of the outer tip. The protrusion may insert into the indention, attaching the hinge portions  132 ,  134  together. Alternately or additionally, a screw, clipping-rod, or the like may be inserted through a hole in the hinge portions  132 ,  134 , attaching them together. 
     The second connector  118  may have a mechanism in place that is adapted to prevent or reduce rotation of the hinge  120 . This mechanism may retain the frame rods  102 ,  104  in place so that the opening  122  is as large as possible. For example, this mechanism may include a piece of material placed over the hinge  120  that prevents the hinge connection from rotating. In some embodiments, the second connector  118  may not have any type of locking mechanism, and the frame rods  102 ,  104  may be held in place relative to each other by the first connector  114 . 
       FIG. 4  illustrates an advantage of using a hinge  120  as the second connector  118 . In  FIG. 4 , the first connector  114  is not attached to the frame rods  102 ,  104 . The benefit illustrated by  FIG. 4  may also be achieved if the first connector  114  is adapted to allow the frame rods  102 ,  104  to rotate towards each other. 
     In  FIG. 4 , the second connector  118  is a hinge  120 . If a locking mechanism for the hinge  120  is provided, it is disengaged in the embodiment illustrated in  FIG. 4 . As illustrated, the first frame rod  102  and the second frame rod  104  can rotate towards each other about the hinge  120 . An angle  400  exists between the frame rods  102 ,  104 . When the net apparatus  100  is to be used, the angle  400  may be between 160 degrees and 200 degrees, such as 180 degrees, so that the opening  122  is as large as possible. However, for storage, the size of the opening  122  is not important. 
     When rotated towards each other, the frame rods  102 ,  104  may cause the angle  400  to be less than 180 degrees. The angle may approach 0 degrees so that the frame rods  102 ,  104  may substantially overlay each other. 
     This is advantageous as it reduces a total area of the net apparatus  100 . The less total area of the net apparatus  100 , the easier it is to store the net apparatus  100  because it can be stored in a smaller amount of space. A smaller area of the net apparatus  100  also provides for less expensive shipping options. 
       FIG. 5  illustrates an embodiment of the net apparatus that utilizes a different hinge  120 . The embodiment illustrated in  FIG. 5  also utilizes a second connector  118  that is formed on the frame rods  102 ,  104  instead of attached to the frame rods  102 ,  104 . The second connector  118  in  FIG. 5  includes two fingers  504 ,  506  attached to the first frame rod  102  and two fingers  508 ,  510  attached to the second frame rod. When attached, the fingers  504 ,  506 ,  508 ,  510  interleave. One, two or more holes  500 ,  502  may exist through the fingers. A pin may be inserted into the hole(s)  500 ,  502  in order to attach the frame rods  102 ,  104  together at the fingers  504 ,  506 ,  508 ,  510 . 
     The pin may be permanently affixed to the second connector  118  or it may be removable. In embodiments where one pin is utilized (inserted into hole  500  or  502 ), the frame rods  102 ,  104  may rotate towards each other. This allows the frame rods  102 ,  104  to substantially overlay each other for ease of storage and shipping. This pin may also be removable so that the frame rods  102 ,  104  can separate for easier storage or shipping. 
     In some embodiments, two pins are utilized. In these embodiments, the second connector  118  may remain rigid, such that the frame rods  102 ,  104  cannot fold towards each other. In these embodiments, one of the pins may be removed such that the frame rods  102 ,  104  can pivot around the remaining pin. Also, both pins may be removed so that the frame rods  102 ,  104  can separate for easier storage or shipping. 
     Returning reference to  FIG. 1 , the hinge  120  may be a barrel hinge, a pivot hinge, a butt hinge, a case hinge, or any other type of hinge. 
     In some embodiments, the first frame rod  102  and the second frame rod  104  may attach directly together. They may attach, for example, via screw threading, any snap connectors including but not limited to those illustrated in  FIG. 2 , spring clips, or the like. 
     For example, the first frame rod  102  may include one part of a snap connector at the distal end  106  and the second frame rod  104  may include the other part of the snap connector at the distal end  108 . In this example, the distal ends  106 ,  108  may attach via the snap connector. 
     In some embodiments, the first frame rod  102  may include male screw threading at the distal end  106  and the second frame rod  104  may include female screw threading at the distal end  108 . In these embodiments, the distal ends  106 ,  108  may attach via the screw threading. 
     In some embodiments, the first frame rod  102  may include a male button part at the distal end  106  and the second frame rod  104  may include a female button part at the distal end  108 . In these embodiments, the distal ends  106 ,  108  may attach via the button. 
     In some embodiments, one distal end  106 ,  108  may be adapted to fit inside the other distal end. In these embodiments, the distal ends  106 ,  108  may be attached by spring clips or similar features. 
     In some embodiments, a hinge  120  may not be included in the second connector  118 .  FIG. 6  illustrates such an embodiment. In  FIG. 6 , a cross section of portions of the first frame rod  102 , the second frame rod  104  and a bracket  600  are illustrated. In this embodiment, the bracket  600  is used as the second connector  118 . 
     In some embodiments, the bracket  600  may have two portions that snap together using any snap connectors including but not limited to those illustrated in  FIG. 2 , spring clips or the like. The two portions of the bracket  600  may attach together enclosing the distal ends  106 ,  108  of the frame rods  102 ,  104 . The inside of the bracket  600  may have the same contours as the distal ends  106 ,  108  of the frame rods  102 ,  104 . Because of this, the bracket  600 , when attached to the distal ends  106 ,  108 , may attach the frame rods  102 ,  104  together. 
     In some embodiments, the bracket  600  may have internal threading and the distal ends  106 ,  108  of the frame rods  102 ,  104  may have external threading. In these embodiments, the bracket  600  may screw onto the frame rods  102 ,  104  to form an attachment. 
     In some embodiments, the distal ends  106 ,  108  of the frame rods  102 ,  104  may include female receptors. The bracket  600  may include two male connectors such that each male connector may be received by a corresponding female receptor at the distal ends  106 ,  108 . The male connectors may attach to the female receptors using a snap connector including but not limited to those illustrated in  FIG. 2 . The male connectors may also attach to the female receptors using a tension fit design. For example, the second connector  118  may be a dowel such that the tension between the dowel and the female receptors attaches the frame rods  102 ,  104  to the second connector  118 . Where used throughout the disclosure, an attachment or connection may refer to a device or system that resists separation of the relative components. 
     Utilizing a design such as the one illustrated in  FIG. 6  provides advantages such as allowing the net apparatus  100  to become less bulky. This is because the frame rods  102 ,  104  are detachable and thus may be stored in a smaller space. For example, one frame rod  102 ,  104  may be placed directly on top of the other frame rod  102 ,  104 . The less space required to store the net apparatus  100 , the easier the storage is. A less bulky net apparatus  100  also provides for less expensive shipping options. 
     In some embodiments, more than two frame rods  102 ,  104  may be included with the net apparatus  100 .  FIG. 7  illustrates an embodiment of the net apparatus  100  that utilizes more than two frame rods. In  FIG. 7, 8  frame rods  700 ,  702 ,  704 ,  706 ,  708 ,  710 ,  712  and  714  are utilized. However, the net apparatus  100  may include any quantity of frame rods and is not limited to the embodiments illustrated herein. 
     In particular, the embodiment of the net apparatus  100  illustrated in  FIG. 7  includes a center proximal rod  700 , a center distal rod  702 , two straight proximal rods  704 ,  706 , two straight distal rods  708 ,  710  and two curved rods  712 ,  714 . 
     The center proximal rod  700  may include a connector  716  adapted to attach the pole  116  to the net apparatus  100 . In other embodiments, the net apparatus  100  does not include a center proximal rod  700 , and instead other rods attach to the first connector  114 , as illustrated in  FIG. 1 . In embodiments such as the one illustrated in  FIG. 7 , the connector  716  may attach to a pole in any manner. For example, threading, any snap connectors including but not limited to those illustrated in  FIG. 2 , spring clips or the like may be used to attach the center proximal rod  700  to the pole  116 . 
     The frame rods  700 ,  702 ,  704 ,  706 ,  708 ,  710 ,  712  and  714  may attach together via threading, any snap connectors including but not limited to those illustrated in  FIG. 2 , spring clips, or the like. For example, the frame rod  708  may have a distal end  720  and the frame rod  702  may have a proximal end  718 . The distal end  720  may be hollow and larger than the proximal end  718 . The proximal end  718  may fit within the distal end  720 . These ends  718 ,  720  may each have holes (not illustrated) that align. A pin, such as a split pin, may be inserted through the holes, thus connecting the two frame rods  708 ,  702  together. 
     In other embodiments, the proximal end  718  may have spring-loaded protrusions on the outside. The distal end  720  may, as in the example above, contain holes. The protrusions may be designed such that when the proximal end  718  is inserted into the distal end  720 , the protrusions extend through the holes, thus attaching the frame rods  708 ,  702  together. 
     The frame rods  700 ,  702 ,  704 ,  706 ,  708 ,  710 ,  712  and  714  may also attach together via any other locking design such as a camlock, a slide lock, a lever lock, or the like. For example,  FIG. 10  illustrates some examples of lever lock designs for attaching two rods together. In some embodiments, the proximal end  718  may be received by the distal end  720 . A locking mechanism, such as those mentioned above, may exist that is adapted to attach the two frame rods  708 ,  702  together. For example, a lever may be depressed when the frame rods  708 ,  702  are in their correct position in order to secure the frame rods  708 ,  702  together. 
     It will be appreciated that any method of attachment discussed herein in regards to any two frame rods, such as frame rods  708 ,  702 , can be applied to any pair of frame rods that are to be attached together. 
     This modularity provides advantages. The net apparatus  100  may be dismantled (by detaching the frame rods  700 ,  702 ,  704 ,  706 ,  708 ,  710 ,  712  and  714 ) so that the net apparatus  100  requires less space for storage and may be shipped at a less expensive rate than a net apparatus that is not modular. 
     Additionally, the ability of the frame rods  700 ,  702 ,  704 ,  706 ,  708 ,  710 ,  712  and  714  to detach allows the user to customize the net for use. For example, if the user wants a larger net apparatus  100 , he can add additional frame rods to the frame rods  700 ,  702 ,  704 ,  706 ,  708 ,  710 ,  712  and  714  illustrated in  FIG. 7 . If the user wants a smaller net apparatus  100 , he can remove frame rods, such as frame rods  704 ,  706 ,  708  and  710 . 
     Different size nets  100  provide advantages and disadvantages. For example, larger nets  100  can collect more debris per sweep of the pool. However, smaller nets  100  may be easier for a smaller person to manipulate. In these embodiments, nettings  124  having different sized perimeters may be provided so that the user can attach a netting  124  that matches whatever configuration of the net apparatus  100  that the user wants to use. 
     In some embodiments and referring to  FIG. 1 , the frame rods  102 ,  104  may include a beveled edge on the distal ends  106 ,  108  of the frame rods  102 ,  104 .  FIG. 6  may be viewed as one of these embodiments as well, such that the distal ends  106 ,  108  illustrated are not cross sections, but instead are beveled edges. The beveled edges may allow the net apparatus  100 , particularly when adapted to be used as a rake, to collect more debris from a bottom or a side of the pool. 
     The net apparatus  100  may be provided with rounded frame rods  700 ,  702 ,  704 ,  706 ,  708 ,  710 ,  712  and  714 , such as those illustrated in  FIG. 7 . It may sometimes be preferable to have a beveled edge on the distal ends of the frame rods.  FIG. 8  illustrates an attachment  800  adapted to provide this beveled edge to the net apparatus  100 . 
     The attachment  800  may have a flat surface  801  and at least one connector  802 . The attachment may have any shape so long as a flat edge exists on a front of the attachment  800 . 
     The connector  802  may be a single connector or multiple connectors  802   a ,  802   b  and  802   c . The connector may be any type of connector including, but not limited to, the snap connectors illustrated in  FIG. 2 , buttons, screw threading, pins, spring clips or the like. In the embodiment illustrated in  FIG. 8 , the connectors  802  are spring clips attached to the attachment  800 . 
     The attachment  800  may attach anywhere on the frame rods  700 ,  702 ,  704 ,  706 ,  708 ,  710 ,  712  and  714 . In a preferred embodiment, the attachment  800  is attached to the frame rods  702 ,  708  and  710  at the front of the net apparatus  100 . In preferred embodiments, the attachment  800  is attached at the bottom of the frame rods  702 ,  708  and  710 . This is because the net apparatus  100  may be collecting debris from the bottom of the pool. 
     When collecting debris from the bottom of the pool, it may be desirable to put downward pressure on the net apparatus  100 . Because of the positioning of the attachment  800  at the bottom of the net apparatus  100 , pressure will not be exerted in such a way as to dislodge the attachment  800 . 
     The attachment  800  may be adapted to attach to frame rods having different shapes. For example, the attachment  800  may be adapted to attach to triangular frame rods, circular frame rods, rectangular frame rods, or the like. 
       FIG. 9  illustrates another embodiment of a net apparatus. The embodiment illustrated in  FIG. 9  includes frame rods  900 ,  902 ,  904 ,  906  and  908 .  FIG. 2  also includes a first hinge  910  and a second hinge  912 . The two hinges  910 ,  912  may include a locking mechanism adapted to lock the hinges  910 ,  912  in an extended position. 
     The embodiment illustrated in  FIG. 1  includes the hinge  120  that allows for rotation of the first frame rod  102  towards the second frame rod  104  along an axis extending from the proximal ends  110 ,  112  of the frame rods  102 ,  104  towards the hinge  120 . The embodiment illustrated in  FIG. 9  includes the hinges  910 ,  912  that allow a proximal half  914  to rotate towards a distal half  916  along an axis that extends from the first hinge  910  towards the second hinge  912 . 
     The locking mechanism allows the hinges  910 ,  912  to remain in an extended position so that the net apparatus  100  can remain in an open position while in use. The locking mechanism may also unlock so that the net apparatus  100  may become smaller for storage or shipment. 
     In the embodiment illustrated in  FIG. 9 , a connector may exist between each frame rod  900 ,  902 ,  904 ,  906  and  908 . This connector may be a snap connector including but not limited to those illustrated in  FIG. 2 , a button, a pin, a spring clip or the like. This allows the net apparatus  100  to be able to be shipped and stored in a smaller package than if the frame rods  900 ,  902 ,  904 ,  906  and  908  were permanently attached. 
     Referring to  FIG. 11 , another net apparatus  1100  is shown. The apparatus  1100  includes a frame  1102  and is designed to function with a netting, such as the netting  1240  of  FIG. 15 . The netting may be attached to the frame  1102  in any manner discussed herein. 
     The frame  1102  includes a plurality of frame rods  1103  and defines an opening  1105  in which the netting may be positioned. The frame rods  1103  define or include a connector  1104  for connection to a pole, such as the pole  116  of  FIG. 1 . For example, the connector  1104  may include a hole  1106 . In some embodiments, the hole  1106  may include threading, a snap connector, or other feature to facilitate a connection between the frame  1102  and the pole. 
     The plurality of frame rods  1103  includes a first frame rod  1108 , a second frame rod  1110 , and a third frame rod  1112 . Each of the first frame rod  1108  and the second frame rod  1110  may be curved. In some embodiments, the first frame rod  1108  and the second frame rod  1110  may resemble a quarter of a circle. In that regard, the combination of the first frame rod  1108  and the second frame rod  1110  may resemble a semicircle. 
     The first frame rod  1108  and the second frame rod  1110  may each have a mating end and a second end. In particular, the first frame rod  1108  has a mating end  1114  and a second end  1118 . The second frame rod  1110  also includes a mating end  1116  and a second end  1120 . The mating ends  1114 ,  1116  are designed to be removably attached together. In that regard, a frame connector may be used to couple the first frame rod  1108  to the second frame rod  1110 . 
     The first frame rod  1108  may include a first hole  1126  at the mating end  1114 , and the second frame rod  1110  may include a second hole  1128  at the mating end  1116 . A U-shaped pin  1130  may function as the frame connector and may have one end inserted into the first hole  1126  and a second end inserted into the second hole  1128 . The U-shaped pin  1130  may resist separation of the first frame rod  1108  from the second frame rod  1110 . Multiple U-shaped pins  1130  may be used between frame rods to increase the stability of the connection between the frame rods. 
     The third frame rod  1112  may be straight, as shown, or may be curved. For example, the third frame rod  1112  may bow out along the X axis and/or along the Z axis. The third frame rod  1112  may be removably attached to the second end  1118  of the first frame rod  1108  and to the second end  1120  of the second frame rod  1110 . 
     In particular, the third frame rod  1112  may be removably attached to the first frame rod  1108  and the second frame rod  1110  via a tongue and groove feature. In particular, the first frame rod  1108  may include a groove  1124  and the third frame rod  1112  may include a tongue  1122 . The tongue  1122  may be received by the groove  1124  and may resist separation of the third frame rod  1112  from the first frame rod  1108 . In some embodiments, the tongue  1122  and the groove  1124  may extend along an entire height  1125  of each of the plurality of frame rods  1103 . The height  1125  is defined along the Z axis. 
     In some embodiments, each of the plurality of frame rods  1103  may be coupled together using the same type of feature or using different features, as shown in  FIG. 11 . In some embodiments, each of the plurality of frame rods  1103  may be coupled together using a tongue and groove feature, a U-shaped pin, a snap connector including but not limited to those illustrated in  FIG. 2 , or the like. 
     Turning now to  FIG. 12 , another net apparatus  1200  is shown. The net apparatus  1200  includes a plurality of frame rods  1203  including a first frame rod  1202 , a second frame rod  1204 , and a third frame rod  1206 . Each of the plurality of frame rods  1203  may be removably attached together. 
     For example and referring to  FIG. 13 , the first frame rod  1202  may include a tongue  1220  and the second frame rod  1204  may include a groove  1222 . The tongue  1220  may be received by the groove  1222  to resist separation of the first frame rod  1202  from the second frame rod  1204 . The first frame rod  1202  may further include a snap fit feature  1216  designed to be received by a slot  1217  of the second frame rod  1204 . The first frame rod  1202  and the second frame rod  1204  may be removably attached together via the tongue and groove  1220 ,  1222  and the snap fit feature and slots  1216 ,  1217 . 
     A cavity  1214  may be defined between the first frame rod  1202  and the second frame rod  1204 . The cavity  1214  may be designed to receive a pole, such as the pole  116  of  FIG. 1 . When the pole  116  is received in the cavity  1214 , the connection of the first frame rod  1202  to the second frame rod  1204  may resist separation of the pole from the frame rods  1202 ,  1204 . 
     Turning now to  FIG. 14 , the second frame rod  1204  may be coupled to the third frame rod  1206  via a tongue and groove feature which also functions as a snap connector. As shown, the second frame rod  1204  includes a tongue  1230  and the third frame rod  1206  includes a groove  1232 . The tongue  1230  is designed to be received by the groove  1232  and to snap in place when received by the groove  1232 . 
     Referring now to  FIGS. 12 and 15 , the net apparatus  1200  further includes a netting  1240 . The netting  1240  is designed to be removably attached to the plurality of frame rods  1203  and to be at least partially positioned within the opening  1212 . The netting  1240  includes a net frame and  1242  and a net  1244 . The net frame  1242  is designed to be removably attached to the plurality of frame rods  1203  such that the net  1244  substantially fills the opening  1212 . 
     In particular, the one or more of the plurality of frame rods  1203  may include or define a slot  1218 . With reference now to  FIGS. 12, 15, and 16 , the net frame  1242  may include one or more tabs  1246  that are designed to be received by the slots  1218 . The tabs  1246  and the slots  1218  may function together as a snap fit feature. In that regard, the tabs  1246  may snap into the slots  1218  and may be removed from the slots  1218  upon manual actuation of a portion of the tabs  1246 . The netting  1240  may be considered to be removably attached to the plurality of frame rods  1203  when the tabs  1246  are received by the slots  1218 . 
     Turning now to  FIG. 17  another net apparatus  1300  is shown. The net apparatus  1300  has a frame  1302  that includes a plurality of frame rods  1303 . The frame  1302  defines an opening  1305  in which a netting may be positioned. The frame  1302  further includes a pole connector  1304  for connecting the frame  1302  to a pole. 
     The plurality of frame rods  1303  includes a pole frame rod  1306 . The pole frame rod  1306  defines or includes the pole connector  1304 . The pole frame rod  1306  may be relatively straight (i.e., extends substantially along the Y axis) or may be curved. The plurality of frame rods  1303  further includes a first end frame rod  1308  and a second end frame rod  1310 . The first end frame rod  1308  and the second end frame rod  1310  may be curved. In some embodiments, the first end frame rod  1308  and the second end frame rod  1310  may each have a semicircular shape. 
     The plurality of frame rods  1303  may further include a first proximal frame rod  1312  and a second proximal frame rod  1314 . The first proximal frame rod  1312  and the second proximal frame rod  1314  may be relatively straight or may be curved. 
     In some embodiments, the first proximal frame rod  1312  and the second proximal frame rod  1314  may each define an auxiliary connector  1316 . The auxiliary connectors  1316  may be designed to attach to a pole to provide additional support for the pole. This may be especially desirable if the frame  1302  is designed to be relatively large because use of the three connectors  1304 ,  1316  attached to the pole may provide sufficient support to move the net apparatus  1300  through water. 
     The plurality of frame rods  1303  may further include a first distal frame rod  1318 , a second distal frame rod  1320 , and a third distal frame rod  1322 . The first distal frame rod  1318 , the second distal frame rod  1320 , and the third distal frame rod  1322  may be relatively straight or may be curved. 
     Each of the plurality of frame rods  1303  may be designed to be removably attached to each of the remaining frame rods  1303 . In that regard, the frame  1302  may be modular. For example, the pole frame rod  1306  and the second distal frame rod  1320  may each be removably attached to the first end frame rod  1308  and the second end frame rod  1310 . A resulting frame would be smaller in the Y direction than the frame  1302  that includes the proximal frame rods  1312 ,  1314 , the first distal frame rod  1318 , and the third distal frame rod  1322 . Similarly, if a user desires a larger frame than the frame  1302  then the user may add additional distal frame rods and proximal frame rods. 
     This modularity is beneficial because it allows a user to utilize net apparatuses with multiple sizes without buying each net apparatus separately. Furthermore, a relatively large net apparatus may be packaged and shipped in a relatively small package. 
     Each of the plurality of frame rods  1303  may be coupled together in one or more fashion. For example, each of the plurality of frame rods  1303  may be coupled together using a tongue and groove feature along with a frame connector. As shown, each of the plurality of frame rods may include a tongue  1328  and a groove  1330 . The tongue  1328  from each frame rod  1303  may be received by the groove  1330  of an adjacent frame rod  1303 . In that regard, each of the frame rods  1303  may be removably attached to each of the other frame rods  1303 . 
     Likewise, each of the plurality of frame rods  1303  may include a first hole  1324  and a second hole  1326 . A U-shaped pin  1327  may have a first side  1332  that may be received by the first hole  1324  and a second side  1334  that may be received by the second hole  1326 . When the U-shaped pin  1327  is received by the holes  1324 ,  1326 , the U-shaped pin  1327  may resist separation of adjacent frame rods  1303 . In some embodiments, each of the plurality of frame rods  1303  may include multiple first holes and multiple second holes such that multiple U-shaped pins are utilized to enhance the connection between adjacent frame rods  1303 . 
     Turning now to  FIG. 18 , another net apparatus  1400  is shown. The net apparatus  1400  has a frame  1402  that includes a plurality of frame rods  1403 . The frame  1402  further includes or defines a connector  1404  for connecting the frame  1402  to a rod. 
     The plurality of frame rods  1403  includes a first frame rod  1406 , a second frame rod  1408 , a first side frame rod  1416 , a second side frame rod  1418 , and a distal frame rod  1420 . The first frame rod  1406  and the second frame rod  1408  may each include a parallel portion  1410  and an angled portion  1412 . The parallel portions  1410  may be positioned adjacent to each other and may be coupled together, such as via a U-shaped pin  1426  inserted into a first hole  1422  and a second hole  1424 . The parallel portions  1410  may further define or include a connector  1404  for connecting the frame  1402  to a pole. 
     The angled portion  1412  of the first frame rod  1406  and the second frame rod  1408  may extend away from the parallel portion  1410  at an angle  1414 . In some embodiments, the angle  1414  may be between 5 degrees and 175 degrees, between 45 degrees and 105 degrees, or the like. 
     The first side frame rod  1416  may be removably attached to the angled portion  1412  of the first frame rod  1406 . The first side frame rod  1416  may form an angle  1415  with the angled portion  1412 . In some embodiments, the angle  1415  may be equal to the angle  1414 . 
     The first side frame rod  1416  and the second side frame rod  1418  may be removably attached to the distal frame rod  420 . For example, such connection may include a tongue and groove connection including a tongue  1430  and a groove  1432 , a U-shaped pin connector, or the like. 
     The first side frame rod  1416 , the second side frame rod  1418 , and the distal frame rod  1420  may be straight, as shown, or may be curved. 
     The frame  1402  may include a plurality of net frame connectors  1428 . The net frame connectors  1428  may form a part of a snap fit connector for coupling the frame  1402  to a net frame of a netting. 
     Turning now to  FIGS. 19 and 20 , another net apparatus  1500  may include a plurality of frame rods  1503 . The net apparatus  1500  may include any quantity of frame rods  1503 . The net apparatus  1500  may further include a frame connector  1506 . The frame connector  1506  may be utilized to connect two frame rods  1503  together. The frame connector  1506  may include any angle, and multiple frame connectors  1506  may be provided with different angles. In that regard, multiple frame rods  1503  and frame connectors  1506  may be utilized to form a frame of a net apparatus. 
     A net frame  1520  may be made of a malleable material such as a rubber or plastic. The net frame  1520  may define a slot  1522  which may receive a portion or all of the plurality of frame rods  1503 . In that regard, a net may be positioned over the plurality of frame rods  1503  prior to insertion of the frame rods  1503  into the slot  1522 . The slot  1522  may be designed to resist separation of the plurality of frame rods  1503  from the net frame  1520 . In that regard, the design of the slot may further resist separation of the net from the plurality of frame rods  1503  and the net frame  1520 . 
       FIG. 21  illustrates a net apparatus  1600  that includes a plurality of frame rods  1602  and a plurality of connectors  1604 . The frame rods may each have an equal length  1610 . In some embodiments, the length  1610  may be between 2 inches and 10 inches, or between 4 inches and 8 inches, or approximately 4 inches, or approximately 8 inches. Where used in this context approximately refers to the stated value plus or minus 10% of the stated value. 
     The angled connectors  1604  may each be designed to connect two frame rods  1602  together. Each of the angled connectors  1604  may have an angle  1608 . In some embodiments the angle  1608  may be fixed, and in some embodiments the angle  1608  may be variable. 
     In that regard, multiple frame rods  1602  and multiple angled connectors  1604  may be combined to create a symmetrical frame  1601 . The frame  1601  may have any number of sides, each corresponding to one frame rod  1602 . For example, the frame  1601  may have 4 sides, 6 sides, 8 sides, 10 sides, 12 sides, or the like. 
     The diameter of the frame  1601  may be determined based on the quantity of frame rods  1602  and the length  1610  of the frame rods  1602 . For example, a frame  1601  with 8 frame rods  1601  and a length  1610  of 4 inches may utilize angled connectors  1604  having an angle  1608  of 135 degrees and may have a diameter of approximately 10.5 inches. As another example, a frame  1601  with 12 frame rods  1601  and a length  1610  of 4 inches may utilize angled connectors  1604  having an angle  1608  of 150 degrees and may have a diameter of approximately 15.5 inches. As yet another example, a frame  1601  with 20 frame rods  1601  and a length  1610  of 4 inches may utilize angled connectors  1604  having an angle  1608  of 162 degrees and may have a diameter of approximately 25.6 inches.
