Title: Storage transport apparatus

Description:
CROSS-REFERENCE TO RELATED APPLICATION 
     This application claims the benefit of U.S. Provisional Application Ser. No. 63/360,788 filed Oct. 28, 2021 for a Storage Transport Apparatus. 
    
    
     FIELD OF THE DISCLOSURE 
     The present invention relates to utility carts for moving articles held thereon, and more specifically, to a storage transport apparatus having a single wheel member. 
     BACKGROUND OF THE INVENTION 
     People look forward to a variety of recreational activities to relax, rejuvenate, and make their leisure time more interesting and enjoyable. However, many of such recreational activities require various accessory items to be brought along so that one can further enhance the experience of that particular recreational activity and enjoy to the fullest. 
     One of the most popular recreational activities is spending a day with family and/or friends at the beach. Basking in the sun, swimming for hours and enjoying the outdoors, a day spent beside the water can help ease the stresses of daily life and can leave one tanned and well rested. Avid beach goers need to pack all sorts of accessory items, such as towels, paperback books, extra dry clothes, umbrellas, coolers filled with food and drinks, suntan lotion, while families with children also must pack an arsenal of toys, skin boards, buckets, and shovels in order to keep their tots happy and engaged. Additionally, most beach goers find it necessary to carry along a large blanket and one or two beach chairs before heading off to the beach. These items are particularly useful in that they provide them comfortable spot to sit back and enjoy the sun&#39;s rays, as well as an area free of sand or debris on which belongings can be neatly stored. However, the burden of transporting all of these accessory items to the beach from the car to a particular spot on the sand and at the same time, ensuring that none of such items is damaged in anyway, can quickly become a time consuming and frustrating task. Trekking across hot sand and making multiple trips to the car in order to transport heavy accessory items, such as coolers, blankets, boogie boards, skin boards, toys, and beach chairs, all while trying to keep an eye on the tots and unattended goods on the beach, can leave one feeling exhausted before the day&#39;s activities have even begun. Furthermore, after spending long hours soaking up the sun, riding the waves and swimming, packing up the heavy accessory items and dragging them back to the car is the last thing most people want to do. 
     A set of existing prior art solutions accomplish the task of transporting the accessory items by using bags and backpacks. However, in such bags and bag packs, the accessory items may not be conveniently stored in an organized manner. Accordingly, the user is prevented from gaining a quick access to any one of these accessory items when required, as the user has to resort to rooting through this common hodgepodge collection until the particular desired accessory item is found. Such a lack of organized storage may also lead to an increased chances of damaging or even breaking fragile accessory items. Consequently, the user has an additional task of cleaning or disinfecting the bags or the bag packs. 
     Another set of existing prior art solutions accomplish the task of transporting the accessory items by using manual transport apparatuses, such as dollies, utility carts, or hand carts. However, such transport apparatuses do not always roll easily over soft sandy terrain and thus, attempting to manually steer a loaded transport apparatus across sand, pebbles or gravel can be extremely difficult. In most of such manual transport apparatuses, large wheels and broad footprints add to the overall size of the apparatus itself, making it bulky and difficult to handle. 
     Motorized transport apparatuses may help the user to save on their efforts of steering the load from the car to the desired spot and vice versa. However, such motorized transport apparatuses are often very high on the cost factor. Further, due to added weight of the motor in addition to the load of the accessory items may cause the tires, that already have insufficient surface area, sink into the soft sand. 
     In spite of these various prior art alternatives, there remains a continuing need for improved storage transportation in a mobile form of apparatus that can move a variety of stored articles more easily and efficiently over different terrains with varied surfaces. All patent applications cited throughout this application are incorporated by reference in their entireties for all purposes. 
     SUMMARY OF THE PRESENT INVENTION 
     Accordingly, it is a general purpose and object of the present invention to provide an improved storage transport apparatus capable of moving a variety of stored articles held thereon from place to place on land with ease and maneuverability despite the surface of the terrain. 
     A more particular object of the present invention is to provide an improved storage transport apparatus especially capable of moving its stored articles with ease of effort upon softer terrains and sandy beach surfaces. 
     Another object of the present invention is to provide an improved storage transport apparatus having an articulated structure that can be made compact when not in use and capable of being deployed when needed for transporting its stored articles. 
     A still further object of the present invention is to provide an improved storage transport apparatus that is easy to use and durable in its construction. 
     These and other objects of the present invention are accomplished by a storage transport apparatus comprising a single wheel member rotatably engaged with a main frame. The single wheel member has an inner shell and an outer shell. The outer shell comprises a pair of shell members secured to a central member, with the pair of shell members of the outer shell being secured to the central member using one or more fastening mechanisms. The central member has a pair of pin structures internally secured at diametrically opposite ends and extending at least towards the inner shell. The inner shell is formed and configured to fit within the outer shell, the inner shell having an outer boundary preferably conforming with the inner shape and contour of the outer shell. The inner shell comprises a pair of shell-bearing members positioned at being rotatably secured to the inner side of a corresponding pin structure extended towards the inner shell. The main frame includes a handle and rotatably engaged with the single wheel member. Each end member of the main frame comprises a corresponding frame bearing member, each end member extending inwardly to rotatably engage with a corresponding pin structure of the central member. In a further aspect of the present invention, the inner shell and the outer shell are hollow in construction, with the inner shell further including a lid configured to open and close for storing a plurality of items for transportation. The inner shell is disposed within the outer shell and adapted to remain upright when the outer shell rolls in a circular motion along a ground surface. The outer shell is configured to protect the inner shell and the plurality of items stored in the inner shell while being rolled along the ground surface for the transportation. 
     Further in accordance with the present invention, the main frame comprises a plurality of holders open in their construction and configured to hold additional items for the transportation. The handle of the main frame is designed to be pivotally anchored to ground for stabilization when the storage transport apparatus is not in motion. The outer members of the pin structures disposed within the central member respectively engage with the end members of the main frame external to the outer wall of the central member with the end members of the main frame being engaged with the outer members of the pin structures within two walls of the central member. The pin structures extended into the inner shell are configured to hold the inner shell such that rolling motion of the outer shell is free from any friction induced by the inner shell. 
     In a further aspect of the present embodiment, the pair of shell members of the outer shell have a plurality of indentations that provides gripping points for a user to disengage one or both of the pair of shell members from the central member. The inner and the outer shells are designed to be insulated to maintain temperature of a plurality of items stored in the inner shell. 
     In another aspect of the present invention, the main frame defines a continuous handle between a pair of spaced-apart longitudinal arm portions with the end members of the main frame extending inwards along a first axis. The first axis is distant from and parallel to a longitudinal second axis of the continuous handle. The pin structures disposed internally within the central member are permanently secured at the diametrically opposite ends along the first axis of the main frame. The pair of spaced-apart longitudinal arm portions extend parallelly with respect to each other towards the handle when the length of the handle is made equal to diameter of the central member. When the length of the handle is made less than diameter of the central member, the pair of spaced-apart longitudinal arm portions extend non-parallelly with respect to each other towards the handle. In accordance with a present embodiment, the main frame further defines a crossbar having a crossbar axis parallel to the longitudinal axis of the continuous handle and disposed between the first axis and the longitudinal axis of the continuous handle. With respect to the first axis, the crossbar is disposed at a distance that exceeds radial length of the single wheel. One or more additional storage units may be mounted on the crossbar using one or more fastening mechanisms. 
     In accordance with an embodiment of the present invention, the main frame comprises a continuous first frame member that proximally traces a contour of an outer boundary of the outer shell across the pin structures. The main frame is a hollow structure fabricated from one of a tubular metal or a synthetic plastic polymer. End members of the main frame extend inwards along a first axis that coincides with an axis of the pin structures. The main frame further comprises a second frame member with a longitudinal second axis orthogonal to the first axis. A proximal end of the second frame member is permanently secured to the circumferential center of the first frame member. A distal end of the second frame member defines the handle extending downwardly with respect to longitudinal axis of the second frame member. The second frame member comprises one or more of an arm member, a pole or a holder to hold additional items for the transportation. 
     In accordance with alternate embodiments, a shape of the single wheel member is one of a spherical shape, an elongated oval shape, or a lateral cylindrical shape. In each respective embodiment, the inner and the outer shells of the single wheel member are fabricated from synthetic plastic polymer. In accordance with a preferred embodiment, the pair of shell members are symmetric with respect to each other such that the central member is arranged at the middle of the single wheel. The pair of symmetric shell members and the central member form a regular shape. In accordance with an alternate embodiment, the pair of shell members are non-symmetric with respect to each other such that the central member is arranged towards one side of the single wheel. The pair of non-symmetric shell members and the central member form a regular shape. 
     For a better understanding of these and other aspect of the present invention, reference should be made to the following detailed description taken in conjunction with the accompanying drawing figures in which like reference numerals and characters designate like parts throughout.

FIG.  1 A  is described in conjunction with  FIGS.  1 B,  1 C,  2 ,  3 A,  3 B,  3 C . 
     Turning to the  FIGS.  1 A,  1 B , IC, and  FIG.  2   , a first storage transport apparatus  100 A and its components constructed and assembled in accordance with the present invention are depicted in different perspectives. As depicted in  FIG.  1 A , there is shown the first storage transport apparatus  100 A that comprises a single wheel member  10 A and a main frame  50 . The single wheel member  10 A and the main frame  50  may be coupled to each other via a pin and bearing assembly  11  on both the diametrically opposite sides of the single wheel member  10 A. One side of the pin and bearing assembly  11 , as depicted as the exploded diagram  150 , includes a first pin structure  30 A from a pair of pin structures  30  and a first shell bearing member  40 A from a pair of shell bearing members  40 . The opposite side of the pin and bearing assembly  11 , not shown in  FIG.  1 A  for the sake of brevity, includes a second pin structure  30 A from the pair of pin structures  30  and a second first shell bearing member  40 B from the pair of shell bearing members  40 . 
     The single wheel member  10 A, that may be also referred to as the single wheel body, is the main section of the first storage transport apparatus  100 A. When being pulled or pushed by a user via the main frame  50 , the entire single wheel member  10 A rolls in a circular motion with the intention of making it much easier to move across unstable or soft ground, in this case, the beach sand. 
     The single wheel member  10 A has an inner shell  12  and an outer shell  14  that are solid shells having inner and outer walls or boundaries. As depicted in  FIG.  1 B  in detail, the inner shell  12  has an inner boundary  12 A and an outer boundary  12 B. Similarly, the outer shell  14  also has an inner boundary  14 A and an outer boundary  14 B. The inner shell  12  is formed and configured to fit within the outer shell  14 , the outer boundary  12 B preferably conforming in shape with the inner boundary  14 A of the outer shell, proximally tracing the contour of the inner boundary  14 A of the outer shell  14 . The inner shell  12  may be designed to conform with the contour of the inner boundary  14 A of the outer shell  14  but not be touching the inner boundary of the outer shell in any way. Such a design and arrangement of the inner shell  12  within the outer shell  14  results in formation of an air gap or space between the inner shell and the outer shell. Also, such an arrangement helps the outer shell  14  to experience a rolling motion that is free from any friction induced by the inner shell  12 . As presented in the alternative embodiments of the single wheel member  10 A depicted in  FIGS.  3 D and  3 E , the inner shell  12  may be rectangular or cubic in form, such as that of a rectangular prism or cuboid, or be formed in the shape of a truncated sphere. 
     In accordance with an embodiment of the present invention, the inner shell  12  and the outer shell  14  may be made hollow in their respective structural forms. Such a hollow structure may provide the outer shell  14  the capability to accommodate the inner shell  12  therein thereby enveloping all or part of the inner shell  12  and providing protection thereto. Similarly, the hollow items while the outer shell  14  is being rolled along the ground surface during the transportation. In an exemplary scenario, the first storage transport apparatus  100 A may correspond to a beach cart that may be rolled along the soft sand terrain on a beach. In such an exemplary scenario, various examples of the plurality of items may include, for example, towels, paperback books, extra dry clothes, umbrellas, coolers filled with food and drinks, suntan lotion, toys, skin boards, buckets, and shovels, and the like. It may be noted that the first storage transport apparatus  100 A may correspond to a different utility cart that may be used in a different terrain with a different plurality of items, without deviation from the scope of the present invention. 
     With reference to  FIG.  1 C , in accordance with an embodiment of the present invention, the outer shell  14  includes a pair of shell members, i.e., a top shell member  16  and a bottom shell member  18 , in addition to a central shell member  20  that is disposed intermediate of and arranged engage the top shell and bottom shell members at the middle of the outer shell  14 . In this arrangement, the top shell member  16  and the bottom shell member  18  of the outer shell  14  may be assembled together and secured to the central member  20  using one or more fastening mechanisms. For exemplary purposes, the top member  16  and the bottom member  18  may have two male connections  16 A and  18 A, respectively. The central member  20  may have complementary female connections along the interior so that the top member  16  and the bottom member  18  may be fitted into the central member  20  securing the complete outer shell  14  together. However, the disclosure may not be limited to the above example, and many other fastening mechanisms may be possible, without deviation from the scope of the present invention. 
     As depicted more clearly in  FIG.  1 B , the pair of shell members of the outer shell  14  of singled wheel member  10 A, namely, the top shell member  16  and the bottom shell member  18 , may have a plurality of indentations  26 A and  26 B respectively formed on the outer boundary  14 B of the outer shell. In one case, the plurality of indentations  26 A and  26 B provide gripping points for a user to engage the top member  16  and the bottom member  18  respectively, with the central member  20 . In another case, the gripping points provided by the plurality of indentations  26 A and  26 B facilitates the user to disengage the top member  16  and the bottom member  18  respectively, from the central member  20 . 
     Further, the inner shell  12  includes a lower body  22  and an upper body  24 , with the upper body  24  being formed and configured to open and close as a lid to the inner shell for storing a plurality of items for transportation. The inner shell  12  may be adapted to open by unscrewing or unlatching the upper body  24  to place or access items stored inside. The inner shell  12  may be further adapted to close by screwing or latching the upper body  24  to store the items inside during transportation. In implementation of the present storage transport apparatus  100 A, the inner shell  12  remains upright when the outer shell  14  rolls in a circular motion along a ground surface, such as a soft sand terrain, during the transportation. The pair of shell bearing members  40  stationed inside the wall of the inner shell  12  allows the inner shell  12  to stay in the upright position and not be affected by the rolling motion of the outer shell  14 . 
     In accordance with the present embodiment, the inner shell  12  and the outer shell  14  are hollow in their respective constructions and may be insulated to maintain temperature of the plurality of items stored in the inner shell  12 . The walls of the lower body  22  of the inner shell  12  along with those of the upper body  24  (i.e., the lid of the inner shell  12 ) and the outer shell  14  may be provided with insulating material and have water-proof surfaces adapted to receive ice or other coolant material along with beverages, food items and the like, which may be retained in a cold and fresh condition for consumption whenever desired by the user. In an exemplary use case, the inner shell  12  and the outer shell  14  may be fabricated from a synthetic plastic polymer, such as polyvinyl chloride (PVC). In other exemplary use cases, the inner shell  12  and the outer shell  14  may be fabricated from other such materials that are durable, strong, and light-weight. 
     With reference to  FIG.  1 A , in accordance with a preferred embodiment of the present invention, the pair of shell members, i.e. the top member  16  and the bottom member  18 , may be symmetric with respect to each other such that the central member  20  is arranged at the middle of the single wheel member  10 A. In such an embodiment, the diametric axes of both the inner shell  12  and the outer shell  14  coincide with a first axis  58  along which the end members  56 A and  56 B of the main frame  50  extend inwards. The pair of symmetric shell members, i.e. the top member  16  and the bottom member  18 , and the central member  20  form a regular shape, such as a sphere, as is depicted in  FIG.  1 A . 
     With reference to  FIG.  2   , in accordance with an alternate embodiment of the invention, there is shown an exemplary single wheel member  10 B. The pair of shell members, i.e. the top member  16  and the bottom member  18 , may be non-symmetric with respect to each other such that the central member  20  is arranged towards one side, such as top side, of the outer shell  14  of the single wheel member  10 B. In such an embodiment, the diametric axis of the inner shell  12  coincides with the first axis  58  along which the end members  56 A and  56 B of the main frame  50  extend inwards. However, the diametric axis of the outer shell  14  does not coincide with the diametric axis of the inner shell  12  and the first axis  58 . The pair of non-symmetric shell members, i.e. the top member  16  and the bottom member  18 , and the central member  20  form a regular shape, such as a sphere, as depicted in  FIG.  2   . 
     In accordance with another preferred embodiment of the present invention, a shape of the single wheel member  10 A may be a spherical shape, as depicted in  FIG.  1 A . Notwithstanding, the disclosure may not be limited, and the shape of single wheel member  10 A may be of an elongated oval single wheel member  10 C (as depicted in a second storage transport apparatus  100 B in  FIG.  3 A ), a lateral cylindrical single wheel member  10 D with regular edges (as depicted in a third storage transport apparatus  100 C in  FIG.  3 B ), or a lateral cylindrical single wheel member  10 E with rounded edges (as depicted in a fourth transport apparatus  100 D in  FIG.  1 C ), without deviating from the scope of the disclosure. 
     With reference to  FIG.  1 A , the central member  20  has a pair of pin structures  30 , such as a first pin structure  30 A (shown in  FIG.  1 A ) and a second pin structure  10 B (not shown in  FIG.  1 A ), internally secured at diametrically opposite ends of the outer shell  14 , along the first axis  58 . As depicted in the exploded diagram  150 , the first pin structure  30 A may include a central portion  32 , which may be of any flat shape, such as circular, oval, rectangular, or a square. The central portion  32  may provide resistance to the inward or outward movement to the first pin structure  10 A so that due to any push or pull, the first pin structure  30 A is not dislocated from the intended position. The first pin structure  30 A may further include a lateral portion  34 , orthogonal to the central portion  32 , with an outer member  34 A and an inner member  34 B. The lateral portion  34  may be cylindrical in shape so that a rotational circular movement of mounted bearings, such as a shell bearing member and a frame member, is facilitated. 
     In accordance with a preferred embodiment of the present invention, as depicted in  FIG.  1 A , outer members of the pair of pin structures  30  do not extend outwards from outer wall of the central member  20 . For example, the outer member  34 A of the first pin structure  30 A extends towards the outer wall of the central member  20 , however the outer member  34 A does not protrude out of the outer wall of the central member  20 . The inner member  34 B protrudes out of the inner wall of the central member  20  in the opposite direction and extends towards the inner shell  12 . The inner member  34 B may be adapted to be inserted into the body of the inner shell  12  from the outer boundary  12 B of the inner shell  12  along the first axis  58 . Further in accordance with the present embodiment, the pair of pin structures  30  extended into the inner shell  12  may be configured to hold the inner shell  12  such that rolling motion of the outer shell  14  is free from any friction induced by the inner shell  12 . For the sake of brevity, only the structure of the first pin structure  30 A is described herein. It may be noted that the structure of the second pin structure  30 B is exactly similar to the structure of the first pin structure  30 A. 
     In accordance with the present invention, the inner shell  12  comprises a pair of shell bearing members  40 , such as a first shell bearing member  40 A (shown in  FIG.  1 A ) and a second shell bearing member  40 B (not shown in  FIG.  1 A ), positioned at diametrically opposite ends, along the first axis  58 . The longitudinal axis of the pair of shell bearing members  40  overlaps with the diametric axis of the inner shell  12 . The outer circular surface of each of the pair of shell bearing members  40  may be affixed within the body of the inner shell  12  by means of, for example, adhesive. The inner circular surface of each of the pair of shell bearing members  40  may be adapted to be mounted on a respective inner member of corresponding pin structure. Thus, each of the pair of shell bearing members  40  is rotatably secured to inner member of a corresponding pin structure extended towards the inner shell  12 . For example, the first shell bearing member  40 A may be rotatably secured to the inner member  34 B of the first pin structure  30 A that is extended towards the inner shell  12 . For the sake of brevity, only the first shell bearing member  40 A rotatably secured to the inner member  34 B of the first pin structure  30 A is depicted and described herein. It may be noted that the second shell bearing member  40 B may also be rotatably secured to the inner member of the second pin structure  30 B extended towards the inner shell  12  from the diametrically opposite direction in the similar manner. 
     When the outer members of the pair of pin structures  30  do not extend outwards from outer wall of the central member  20 , end members  56 A and  56 B of the main frame  50  are engaged with the outer members of the pair of pin structures  30  within two walls of the central member  20 , via a first frame bearing member  38 A (shown in  FIG.  1 A ) and a second frame bearing member  38 B (not shown in  FIG.  1 A ). The first frame bearing member  38 A and the second frame bearing member  38 B may be secured and affixed inside the end members  56 A and  56 B respectively, of the main frame  50 . 
     In accordance with an embodiment, not depicted in  FIG.  1 A , outer members of the pair of pin structures  30  extend outwards from outer wall of the central member  20 . For example, the outer member  34 A of the first pin structure  30 A extends towards the outer wall of the central member  20  and protrudes out of the outer wall of the central member  20 . The end members  56 A and  56 B of the main frame  50  are engaged with the outer members of the pair of pin structures  30  external to the outer wall of the central member  20 , via the first frame bearing member  38 A and the second frame bearing member  38 B, respectively. 
     Thus, to summarize, the main frame  50  and the single wheel member  10 A connects with the pair of pin structures  30 , such as metal pins, that are stationed inside the side walls of the outer shell  14  and the inner shell  12 . For example, the first pin structure  30 A may run through the outer member  34 A and the inner member  34 B and the first shell bearing member  40 A. The main purpose of the first shell bearing member  40 A stationed on the inside the wall of the inner shell  12  allows the inner shell  12  to stay in an upright position and not be affected by the rolling motion of the outer shell  14 . The first pin structure  30 A also holds the inner shell  12  up so that there is no friction between the inner shell  12  and the outer shell  14 . The first frame bearing member  38 A is stationed inside of the end of the main frame  50  which is inserted in the side of the outer shell  14  allows the main frame  50  to pull or push the first storage transport apparatus  100 A and allow the outer shell  14  to roll from one location to another. 
     The main frame  50  includes a handle  52  and is rotatably engaged with the single wheel member  10 A. Each end member, such as the end members  56 A and  56 B, of the main frame  50  comprises a corresponding frame bearing member, such as the first frame bearing member  38 A and the second frame bearing member  38 B. Each end member, such as the end members  56 A and  56 B, may extend inwardly to rotatably engage with a corresponding pin structure of the central member  20  along the first axis  58 . In accordance with an embodiment, the main frame  50  may be light-weight, durable, and strong so that the user can easily push or pull the first storage transport apparatus IOOA. The main frame  50  may be a hollow structure fabricated from one of a tubular metal (such as aluminum) or a synthetic plastic polymer. 
     In accordance with an exemplary embodiment, the main frame  50  may define the continuous handle  52  between a pair of spaced-apart longitudinal arm portions  54 A and  54 B. The end members  56 A and  56 B of the main frame  50  extend inwards along the first axis  58 . The first axis  58  is distant from and parallel to a longitudinal axis  60  of the continuous handle  52 . The pair of pin structures  30  internally are permanently secured within the walls of the central member  20  at the diametrically opposite ends, along the first axis  58 . 
     The pair of spaced-apart longitudinal arm portions  54 A and  54 B may extend parallelly with respect to each other towards the handle  52 , with the length of the handle  52  being equal to diameter of the central member  20 . Alternatively, the pair of spaced-apart longitudinal arm portions  54 A and  54 B may converge while extending towards the handle  52 . In this alternative case, the pair of spaced-apart longitudinal arm portions  54 A and  54 B extend non-parallelly with respect to each other towards the handle  52 , with the length of the handle  52  being less than diameter of the central member  20 . In accordance with alternate embodiments of the present invention, the corners of spaced-apart longitudinal arm portions  54 A and  54 B may be rounded or angled. 
     In accordance with an exemplary embodiment of the present invention, the main frame  50  comprises a plurality of deployable holders, such as a first set of holders  64 A and a second set of holders  64 B seen in  FIG.  1 A , which when deployed and opened, are configured to hold additional items for the transportation. In accordance with another embodiment, when not in use, the plurality of holders may be closed. In an alternate embodiment, the handle  52  of the main frame  50  may be extended downwards to be anchored to ground for stabilization when the first storage transport apparatus  100 A is not in motion. As a further alternate form of the main frame  50 , the first set of holders  64 A, as depicted in  FIG.  4 B , may be anchored to the ground for stabilization. 
     The main frame  50  may further define a crossbar  62  having a crossbar axis parallel to the longitudinal axis  60  of the continuous handle  52  and disposed between the first axis  58  and the longitudinal axis of the continuous handle. In accordance with this embodiment of the present invention, with respect to the first axis  58 , the crossbar  62  may be disposed at a distance that exceeds radial length of the single wheel member  10 A. An additional storage unit may be mounted on the crossbar  62  using one or more fastening mechanisms. 
     Thus, the main frame  50  serves multiple purposes. For example, the main frame  50  may act as the handle  52  for either pulling or pushing the first storage transport apparatus  100 A when transporting items to the destination. The handle  52  of the first storage transport apparatus  100 A may be designed in such a manner, for example, to have a downward extension  78  (depicted in  FIG.  4 B ), such as to not only allow multiple people to pull or push the first storage transport apparatus  100 A, but also allow the user to place the handle  52  down and push in the sand when the destination is reached, thus acting as an anchor for stabilization. 
     In another example, frame  50  may act as a holder for transporting additional items. It may have poles or arms that may be opened and closed so that items can be held while being transported. Later on, attachments may be sold to extend such section allowing for more items to be carried. The extension may increase the length of the device as well. The design may vary so that it not only acts as a way to pull the first storage transport apparatus  100 A, but also be able to carry and/or hang items for transportation. 
     Turning to  FIGS.  4 A and  4 B , there is depicted a fifth storage transport apparatus  100 E, in accordance with an embodiment of the present disclosure.  FIG.  4 A  depicts a top view of the fifth storage transport apparatus  100 E and  FIG.  4 B  depicts a handle of the main frame  50  of the fifth storage transport apparatus  100 E. According to this embodiment, as depicted in the fifth storage transport apparatus  100 E of  FIG.  4 A , the main frame  50  comprises a continuous first frame member  70  that proximally traces a contour of an outer boundary of the outer shell  14  across the pair of pin structures  30 . End members  56 A and  56 B of the main frame  50  extend inwards along the first axis  58  that coincides with an axis of the pair of pin structures  30 . In further accordance with this embodiment, the main frame  50  further comprises a second frame member  72  with a longitudinal second axis  74  orthogonal to the first axis  58 . A proximal end  72 A of the second frame member  72  is permanently secured to the circumferential center of the first frame member  70 . A distal end  72 B of the second frame member  72  defines the handle  52  extending downwardly with respect to longitudinal second axis  74  of the second frame member  72 . The second frame member  72  comprises holding members, such as arms  76 A and a holder  76 B, to hold additional items for the transportation.
