Title: Elevated storage for transportation and storage of food items

Description:
BACKGROUND OF THE INVENTION 
     1. Field of the Invention 
     The invention relates to the transportation and storage of food items and specifically to a novel elevated storage device for transporting and storing one or more food items. 
     2. Related Art 
     Storage of food items can be a complex and expensive process. Traditional storage facilities are often designed for the storage and transportation of relatively large quantities of food items. Thus, they are not well suited for storing smaller quantities of food items like those associated with individuals or small businesses. Similarly, traditional storage facilities are generally not configured to allow food items to be easily transported from one location to another as food items must first be removed from the storage facility and placed in a vehicle for transport. 
     In many cases, the purchase or lease of a warehouse would not be appropriate in terms of size and cost for the storage of an individual&#39;s food items. An individual may of course use consumer storage facilities to store and transport food items. However, this may be insufficient. For example, food items may be stored in an individual&#39;s personal property, such as a room of their home or other dwelling or even a storage unit. However, this may not adequately protect the food items and is inconvenient due to the space requirements for the items. 
     Transporting food items with one&#39;s personal vehicle or even a rental vehicle may not be desirable especially for long distances. This is primarily because these vehicles are not designed to protect food items. Also, the storage of food items in a personal vehicle is inconvenient due to the space requirements for the items. 
     In addition, transportation and storage of food items traditionally requires a transport mechanism, such as a vehicle, as well as a storage mechanism, such as a storage facility. These separate mechanisms add additional cost and labor to the storage and transport of food items. 
     Thus, what is provided herein is a novel container elevated storage device for the storage and convenient transport of food items. 
     SUMMARY OF THE INVENTION 
     An elevated storage device for storage and transport of food items is provided herein. The elevated storage device protects the food items allowing them to be stored for long periods. In addition the food items are protected during transport and do not have to be unloaded for storage because they may be safely stored in the elevated storage device. It is contemplated that items other than food items may be stored and transported by the elevated storage device if desired. 
     In one embodiment, the elevated storage device comprises a base comprising a rigid frame, one or more wheels attached to the base, at least one hitch attached to the base, and a storage compartment. The storage compartment may comprise a triangular skeleton and a protective cover around the triangular skeleton, and may also be attached to the base. The protective cover may comprise an opening to allow access to the closed compartment for loading and unloading food items. 
     The protective cover may comprise one or more layers of material. For example, the protective cover may comprise an inner and outer layer, the inner layer being a flexible layer and the outer layer being a rigid mesh layer. The protective cover may also comprise an inner and outer layer where the inner layer is a fabric layer and the outer layer being is wire mesh layer. The protective cover may also comprise at least one insulating layer in one or more embodiments. 
     In one embodiment, the elevated storage device may comprise a skeleton, a protective cover around the skeleton, a base configured to support the skeleton and the protective cover whereby at least a portion of the protective cover is between the skeleton and the base, one or more wheels attached to the base, and at least one hitch attached to the base. The skeleton may have various shapes such as a triangular or semicircular shape in one or more embodiments. The protective cover will typically, but not always, have opening to allow one or more food items to be placed on the base of the elevated storage device. 
     Similar to the above, the protective cover here may also comprise one or more layers of material. For example, the protective cover may comprise a fabric layer and a rigid mesh layer. In addition, the protective cover may comprise a waterproof layer and a rigid mesh layer. Further, the protective cover may comprise an insulating layer and a rigid mesh layer. It is contemplated that the protective cover may comprise an outermost layer, the outermost layer being a wire mesh layer in one or more embodiments. 
     The elevated storage device may include a conveyer system to automate loading and unloading of the elevated storage device. In one embodiment the elevated storage device further comprises one or more guides having one or more channels, and a conveyer system comprising a plurality of rollers and a conveyer belt, the conveyer system retained in the one or more channels of the one or more guides. Typically, but not always, the one or more guides will be attached below the base. 
     A method for storing and transporting food items with an elevated storage device is also provided. In one embodiment the method comprises providing access to an interior portion of a protective cover by opening one or more layers of the protective cover, moving one or more food items to an elevated position corresponding to the base of the elevated storage device, placing one or more food items within the interior portion of the protective cover whereby the one or more food items are placed on top of at least a portion of the protective cover and the base, and closing the one or more layers of the protective cover such that the one or more food items are surrounded by the protective cover. 
     Depending on the embodiment, opening the one or more layers of the protective cover may comprise various steps. For example, opening the one or more layers of the protective cover may comprise opening a rigid mesh layer of the protective cover and a flexible layer of the protective cover. In addition, opening the one or more layers of the protective cover may comprise opening a wire mesh layer of the protective cover and a fabric layer of the protective cover. Further, opening the one or more layers of the protective cover may comprise opening an insulating layer of the protective cover. 
     The elevated storage device may be moved according to the method as well. For instance, in one embodiment, the method may include attaching a hitch of the elevated storage device to a vehicle, moving the elevated storage device to a delivery location, opening one or more layers of the protective cover to access the one or more food items, and removing the one or more food items. 
     Once delivered or when desired, food items may be removed from the elevated storage device according to the method. In one embodiment the method may include removing the protective cover from a supporting skeleton, inserting the skeleton into a new protective cover comprising at least one distinct layer whereby the at least one distinct layer is different from one or more of the one or more layers of the protective cover, and attaching the new protective cover to the base of the elevated storage device.

     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS 
     In the following description, numerous specific details are set forth in order to provide a more thorough description of the present invention. It will be apparent, however, to one skilled in the art, that the present invention may be practiced without these specific details. In other instances, well-known features have not been described in detail so as not to obscure the invention. 
     In one or more embodiments, the elevated storage device herein provides protection, mobility, or both to one or more food items. As used herein, food items refers to edible matter. It is contemplated that the elevated storage device will be typically, but not always, configured to store food items comprising biological or natural material such as food products or other agricultural products. For example, some of the food items that may be transported and stored include but are not limited to as grain, wheat, barley, rye, maize, or rice, and potatoes. The food items may be transported and stored within an elevated storage device in their own packaging such as but not limited to sacks, boxes, bags, and crates. It is noted that non-food items may also be stored and transported with the elevated storage device herein as well. 
     Food items are vulnerable to a variety of external elements. For example, food items may rot, decay, or otherwise degrade when exposed to high humidity, heat, cold, or rain. Food items comprising biological material may be vulnerable to vermin, insects, rodents, or other animal life. In addition, these types of food items provide a nutrition source for other life forms, including mold and bacteria which can rapidly destroy a food item. The fact that the food items may be food products only increases the risk of damage to the items as it serves to attract destructive forces seeking a source of food. Worse yet, contamination of a portion of the food items may render all the food items undesirable, unusable, or even hazardous for human consumption. 
     In general, the elevated storage device protects food items by providing physical barriers to external elements which may damage the items. The elevated storage device also stores food items at an elevated position above the ground. This protects the food items from water damage that would ordinarily occur if the food items were stored low to the ground. It is contemplated that the elevated storage device may be configured such that food items are stored several feet off the ground. In this manner, food items may be protected even from large floods. Additionally, as will be discussed below, the elevated storage device allows food items to be transported while the food items remain protected. In this manner, the elevated storage device may provide both transportation and storage of food items in a convenient manner. 
     This is advantageous to individuals, small business, and others which may not have the quantities of food items sufficient to justify specialized equipment for the transport and storage of food items. In fact, the elevated storage device is very well suited for individuals, government entities, and small businesses having food items too numerous to be adequately stored or transported by make shift or consumer grade transportation and storage mechanisms. 
     To illustrate, a small farmer or distributor may produce a quantity of grain (or other food items) that is difficult to transport, let alone store, in his or her personal vehicle(s). Rather than purchase or lease a specially designed vehicle and storage facility, the small farmer may utilize the elevated storage device herein to safely store the grain (or other food items) conveniently and inexpensively. 
     It is contemplated that the elevated storage device may also be advantageous to larger businesses and others who have large quantities of food items. This is because a plurality of elevated storage devices may be used to store and transport large quantities of food items as will be described further below. The plurality of elevated storage devices, when combined, may be used as a warehouse to store numerous food items. 
     The elevated storage device will now be described with regard to the figures.  FIG. 1  illustrates an exemplary elevated storage device comprising a base  104 , one or more wheels  108 , and a protective cover  112 . In one or more embodiments, the elevated storage device may include a hitch which allows the trailer to be pulled or otherwise moved. As will be described further below, the protective cover  112  may be used to protect the food items, while the one or more wheels  108  and hitch  316  allow the food items to be easily transported. 
       FIGS. 2A-2B  illustrate various embodiments of a base  104  for the elevated storage device. The base  104  generally provides a structure to which other elements of an elevated storage device may be attached. For example, as shown in  FIG. 1 , the protective cover  112 , hitch  316 , and wheels  108  are supported by the base  104 . The base  104  also provides a structure which supports the one or more food items a user desires to place in the elevated storage device. 
     Typically, the base  104  will be constructed from one or more rigid materials to give the base  104  a rigid structure capable of supporting its elements as well as the food items. The rigid structure of the base  104  also may allow the elevated storage device to transport food items across rough terrain. In addition, the rigid structure adds to the reliability of the elevated storage device. 
     In one embodiment, the base  104  may be constructed from one or more metals. Typically, but not always, steel will be used to construct the base  104 . It will be understood that other suitably rigid materials, such as but not limited to wood, plastic, carbon fiber, alloys, or a combination thereof may be used. It is noted that the material chosen may depend on the environment the elevated storage device is to be used in. For example, in high humidity areas, a rust resistant material may be used. The material chosen may also depend on the intended load of the elevated storage device. For example, if intended to transport a relatively small amount of material, wood or plastic may be used. Of course, though additional maintenance may be required, various materials may be used regardless of how or where the elevated storage device is intended to be used. 
     Though shown as rectangular in shape, it is noted that the base  104  may have various shapes. For example, the base  104  may have a rounded shape or a square shape. It is contemplated that the base  104  may be shaped according to its intended use in one or more embodiments. For example, if intended to be parked in a parking lot, the base  104  may be a rectangular shape corresponding to a parking space. If intended to store food items of a particular size, the base  104  may be shaped to allow a plurality of such items with little wasted space. It is noted that the shape of the base  104  generally defines the peripheral shape of the elevated storage device (when viewed from above) in one or more embodiments. 
     In some embodiments, the base  104  may have a planar top  208  such as shown in  FIG. 2A . This allows various types of food items to be placed on the base  104 . As will be described further below,  FIG. 2C  illustrates an exemplary base  104  without a top  208 . 
     The top  208  of the base  104  may include one or more openings  212  in some embodiments. This is illustrated in  FIG. 2B  where the top  208  has a plurality of square openings  212 . The openings  212  allow for ventilation and lighten the overall weight of the base  104  and the elevated storage device while allowing the top  208  to support food items. The ventilation may be desirable for certain food items where circulation of air helps prevent the rot, mold or bacterial growth, and other degradation of the items. The openings  212  may also allow any accumulated moisture to drain through the bottom of the elevated storage device further preventing degradation of the food items. 
     As stated, the openings  212  shown in  FIG. 2B  are generally square in shape. It is noted that openings  212  of other shapes may be used. In addition, the openings  212  may be various sizes. Openings  212  of various sizes and shapes allow the base  104  to support different food items. For example, some food items may undesirably protrude through an opening  212  if the opening is too large. In addition, some food items may fall through an opening  212 . It is contemplated that the openings  212  may also be sized and shaped to prevent access to the food items by one or more insects, rodents, other animals, humans, or other external elements. 
     In one or more embodiments, the base  104  may comprise a frame  204  which forms a rigid structure to which other elements of the elevated storage device may be attached. An example of this is illustrated in  FIG. 2C . As shown, the frame  204  comprises one or more elongated members which generally form the rectangular structure of the base  104 . The frame  204  may be formed from rigid materials similar to those described above in one or more embodiments. It will be understood that the frame  204  may be configured in various shapes and sizes and formed with various connected members or structures in one or more embodiments. 
     In embodiments having a top  208 , the top may be attached to the frame. It is contemplated that the top  208  may be removably attached in one or more embodiments to allow tops to be replaced when worn or with other tops better suited for the task at hand. Removable attachment may be accomplished by one or more fasteners such as but not limited to screws, nuts, bolts, clips, clamps, hook and loop, magnets, or a combination thereof. It is contemplated that the frame  204  may include one or more guides such as one or more protrusions or channels which help to properly locate and secure a top  208  in place. For example, the frame  204  may have one or more protrusions which correspond to openings or depressions on the bottom side of the top  208 . Alternatively, or in addition, the frame  204  may include one or more channels which a top  208  may slide into. The top  208  may then be secured in place by one or more screws, bolts, or other fasteners if desired. Of course, the top  208  may be suitably secured without additional fasteners in one or more embodiments. 
     In one or more embodiments, wheels  108  may be attached to the base  104  to allow the elevated storage device to be moved. It is contemplated that the elevated storage device may comprise one or more wheels  108  such as illustrated in  FIGS. 3A-3C . Typically, but not always, the elevated storage device will comprise at least two wheels  108 . This increases stability of the elevated storage device as it is moved and when it is stationary. It is noted however that an elevated storage device with one wheel  108  may provide superior maneuverability at the cost of stability. 
     Various types of wheels  108 , now known or later developed, may be used with the elevated storage device. For example, automobile, bicycle, motorcycle, and other vehicle wheels may be used with the elevated storage device. In one embodiment, a wheel  108  comprises a circular hub or center portion surrounded by a traction portion. For example, the wheel  108  may be a metal hub around which an inflatable rubber or other tire is attached for traction. In another embodiment, a wheel  108  may comprise a metal traction portion such as in the case of a wagon wheel or train wheel. 
     The wheel  108  or wheels may be mounted on one or more axles  304  attached beneath the base  104  in one or more embodiments. In some embodiments, however, the wheels  108  may be attached on the sides of the base  104  such as shown in  FIG. 3A . It will be understood that the one or more wheels  108  and axles  304  may be attached at various other locations which allow the elevated storage device to move on its wheel(s). For example, one or more axles  304  may be mounted above (or below) the base  104  in a wheel well or the like in one or more embodiments. 
     In one or more embodiments, each wheel  108  may have its own axle  304  such as shown in  FIGS. 3A and 3C . In other embodiments axles  304  may be shared by a plurality of wheels  108  such as shown in  FIG. 3B . An axle mount  312  may be used to secure an axle  304  to the base  104  of an elevated storage device in one or more embodiments. It is contemplated that an axle  304  may turn in one or more embodiments to allow one or more wheels  108  to be steerable. 
     It is noted that the wheels  108  raise the height of the base  104  such that the base does not touch the ground in one or more embodiments. This allows food items to be stored at an elevated position above the ground which provides protection from vermin rodents, water, dust, dirt, debris, and other external elements which may occur at ground level. The wheels  108  may thus be various diameters to raise the height of the base  104  as desired. 
     In one or more embodiments, the base  104  of the elevated storage device may include a hitch  316 . It is noted that a hitch  316  is not required and thus may not be provided in all embodiments. It is also noted that in one or more embodiments, a hitch  316  may be provided as an add-on component. To illustrate, a hitch may be attached to the base  104  of the elevated storage device in  FIG. 1 . 
     Referring back to  FIGS. 3A-3C , when attached, a hitch  316  generally provides a connection point through which a force may be applied to the elevated storage device to move the trailer. For example, the elevated storage device may be pulled, pushed, or otherwise moved through its hitch  316 . A hitch  316  may also be used to attach a plurality of elevated storage devices together. In this manner, elevated storage devices may support one another, be moved together, or both. 
     A hitch  316  may also increase the stability of the elevated storage device when in motion and stationary. For example, one or more hitches  316  may be connected to a vehicle or a stationary structure to support and thus increase the stability of the elevated storage device. In one or more embodiments, a hitch  316  may be used to secure an elevated storage device in place. For example, the hitch  316  may include a locking mechanism which prevents the hitch from being released unless the proper key or code is used. In one embodiment, the elevated storage device may be locked with a chain and padlock. 
     This can be seen by the embodiments of  FIGS. 3A and 3C , which may tilt when not connected to a supporting vehicle, structure, or object. As can be seen, the hitch of these figures is connected to a stationary object  308  by a rigid connector  324 , such as a metal connector, or a flexible connector  320 , such as a strap or tie. It is contemplated that a plurality of hitches  316 , such as shown in  FIG. 3C , may be provided in one or more embodiments to provide additional stability or to spread the load that would ordinarily be borne by a single hitch. 
     A hitch  316  may be any structure capable that allows a sufficiently strong physical connection to the elevated storage device. The strength of the connection may be determined by the load, weight, speed, stability and other characteristics of the elevated storage device when in use. In one embodiment, the hitch  316  comprises a hole or opening through which a screw, bolt, peg, strap, or other structure may be inserted to connect the elevated storage device to another object, such as a vehicle. In another embodiment, the hitch  316  comprises a protrusion that may be inserted or held by a portion of another object to connect the elevated storage device to such object. The hitch  316  may be various existing devices as well. For example, the hitch  316  may a trailer hitch which allows a connection to a vehicle such as a bicycle, car, truck, or the like. The hitch  316  may also be a harness attachment point which connects to a harness to allow one or more people or animals to move the elevated storage device. 
     It is contemplated that one or more handles may be provided in addition to or instead of a hitch in one or more embodiments to allow a person to move the elevated storage device. In addition, it will be understood that the elevated storage device may be pulled, pushed, or otherwise moved even if it does not include a hitch. For example, the elevated storage device may be pushed by its base. 
     The protective cover  112  may be configured in various ways to protect various food items from various external elements. In one or more embodiments, the protective cover  112  provides a physical barrier between external elements and the food items. In general, the protective cover  112  prevents external elements from reaching food items within the elevated storage device by providing a compartment in which food items may be placed. The compartment may protect food items from all directions in one or more embodiments. For example, as shown in  FIG. 1 , the protective cover  112  provides a compartment which surrounds a volume of space on all sides. Food items placed within the compartment would thus be protected from all directions. As will be discussed further below, a protective cover  112  may be attached to the base  104 , top, or both in one or more embodiments. 
     Referring to  FIG. 1 , the protective cover  112  may be formed from one or more materials capable of providing such a barrier between the external elements and the food items. In one embodiment, the protective cover  112  may be formed from natural or synthetic fabrics or sheets such as but not limited to plastic, canvas, burlap, nylon, denim, KEVLAR® (trademark of DuPont), TYVEK® (trademark of DuPont) or a combination thereof. The sheets will typically, but not always, be flexible. It is contemplated that fabric or other sheets may be treated or constructed such that it they are waterproof. This allows the fabric to prevent water from reaching the food items. 
     The protective cover  112  may also be formed from rigid or semi-rigid materials and structures as well. For example, the protective cover  112  may be formed from materials such as but not limited to wire, wood, metal, fiberglass, carbon fiber, cement board, foam, or a combination thereof. These materials may be treated or constructed such that they are waterproof as well. 
     The protective cover  112  may have one or more layers in one or more embodiments such as shown in  FIG. 4 . Each layer may comprise a particular material. Each layer may also be substantially solid, such as a plastic sheet or fabric, or may have an open configuration such as a mesh or web. The one or more layers of a protective cover  112  may be connected by one or more fasteners or adhesives. In one embodiment, the one or more layers may be sewn together.  FIG. 4  shows a portion of an exemplary protective cover  112  having an inner layer  404  and an outer layer  408 . In this embodiment, the inner layer  404  is a fabric material while the outer layer  408  is a mesh. As used herein, the outer or outermost layer  408  will refer to the layer of a protective cover not covered by any other layer. It is noted that there may be multiple inner layers and generally only one outer or outermost layer in one or more embodiments. It will be understood that a variety of different layers may be used to form a protective cover  112  in one or more embodiments. 
     The various layers of a protective cover  112  are advantageous in that each layer may be configured to protect the food items from one or more particular external elements. For example, a fabric layer may be used to protect from rain, humidity, wind, and UV light. A foam or other insulating layer may be used to protect from harmful temperatures. A wire or other mesh layer may be used to protect from physical damage caused by objects, animals, or people. 
     The protective cover  112  may be configured in various shapes and sizes. In one embodiment, the protective cover  112  has a triangular shape such as shown in  FIGS. 5A-5B . This is advantageous in that the slanted shape of the protective cover  112  helps shed water, dust, and other external elements that may come into contact with the protective cover. In addition, the slanted shape prevents rain, snow, and the like from accumulating and potentially causing the protective cover  112  to sag or break. Of course, the protective cover  112  may come in other shapes as well. For example, the protective cover  112  may be rectangular, circular, semi-circular, round, or other shapes. 
     A portion of the protective cover  112  may be removable or may be configured to open to allow food items to be placed inside and removed from the elevated storage device.  FIG. 5A  shows a protective cover  112  with its front portion open. It is noted that a protective cover  112  may be configured to open in various ways. 
     In one or more embodiments, the protective cover  112  may have a portion held closed by, and thus may be opened through, one or more fasteners  512 . As shown in  FIG. 5A , fasteners  512  generally border the opening at the front portion of the protective cover  112  to allow the protective cover to be opened and closed. Various types of fasteners  512  may be used, including but not limited to, one or more zippers, buttons, snaps, hook and loop, or other fasteners, or a combination thereof to allow a portion of the protective cover  112  to be opened. As shown in  FIG. 1 , for example, a hook and loop fastener  120  is used to allow the protective cover  112  to be opened. In one embodiment, a fastener  512  may be locked to prevent the protective cover  112  from being opened without authorization. For example, a combination lock, padlock, or other lock may be used with a fastener  512  to prevent the fastener from being opened without a key or code. In one embodiment, a lock is used to prevent the slider of a zipper from moving thus preventing unauthorized opening. 
     Generally, opening the protective cover  112  includes opening a portion of each layer of the protective cover by undoing one or more fasteners  512 . It is contemplated that each layer may have its own fasteners  512 . For example, each layer may have its own zipper. It is also contemplated that the layers may share one or more fasteners  512 . For example, multiple layers of the protective cover may be sewn or otherwise attached to a single zipper or other fastener  512 . It is contemplated that the protective cover  112  may include one or more hinges to allow the protective cover to be opened. 
     When desired, the protective cover  112  may be closed as shown in  FIG. 5B . In this manner, food items may be protected on all sides from external elements. The protective cover  112  may be closed by using the one or more fasteners  512  to secure the previously opened portion of the protective cover such that it is closed. For example, one or more zippers may be zipped to secure a previously opened portion of a protective cover. 
     The protective cover  112  may have a bottom portion  504  in one or more embodiments. In this way, the protective cover  112  may wrap around the bottom of the food items to protect the food items from all directions. In use, food items may be placed within the protective cover  112  on the bottom portion  504  of the protective cover. The base  104  may support the bottom portion  504  to prevent the bottom portion from sagging or breaking. It is noted that, in one or more embodiments, the protective cover  112  may not have a bottom portion  504  as the base of the elevated storage device may protect the bottom of the food items. 
     It is contemplated that in embodiments without a bottom portion  504 , food items may be placed on the base of an elevated storage device and the protected by lowering a protective cover  112  over the food items. In these embodiments, the protective cover  112  does not need to be configured to open as it may be lifted off the base of the elevated storage device to allow one or more food items to be placed or removed in the elevated storage device. 
     In one or more embodiments, the protective cover  112  may be rigid or semi-rigid to allow it to hold its shape. One or more of layers of a protective cover  112  may configured to support the weight of the protective cover  112  allowing it to hold a shape. For example, the protective covers  112  of  FIGS. 5A-5B  include a wire or other mesh layer which allow the protective covers  112  to hold their triangular shapes. 
     In addition, or alternatively, a protective cover  112  may be supported by a skeleton  508  which allows or helps a protective cover  112  hold its shape. Generally, the skeleton  508  will be a rigid or semi-rigid structure capable of holding the shape of the protective cover  112 . The skeleton  508  may comprise one or more elongated members in some embodiments. It will be understood that any suitably rigid material may be used to form the skeleton including but not limited to metal, plastic, wood, allows, carbon fiber, fiberglass, or a combination thereof. The skeleton  508  may be attached to the base of an elevated storage device by one or more fasteners including but not limited to nuts, bolts, screws, pins, clamps, clips, or a combination thereof. The skeleton  508  may also be welded to the base in some embodiments. It is contemplated that the skeleton  508  may not be attached to the base and instead be held to the base by a protective cover  112  which is attached to the base. 
     The protective cover  112  may be configured to generally conform to the shape of the skeleton  508  allowing the protective cover to be secured to the skeleton without fasteners and to take the shape of the skeleton. Of course, the protective cover  112  may also be secured by one or more fasteners if desired. For example, the protective cover  112  may be sewn, screwed, welded, tied, or otherwise attached to its skeleton  508 . The skeleton  508  may be configured in various shapes to give the protective cover  112  various shapes. For instance, in  FIG. 5C , the skeleton  508  is a triangular shape. 
     It is contemplated that the protective cover  112  may be removable in one or more embodiments. In these embodiments, a protective cover  112  may be replaced because it is worn or damaged, or may be replaced with a protective cover  112  better suited for the food items and external elements at hand. In general, the protective cover  112  may be made removable by utilizing one or more removable fasteners to attach the protective cover. For example, one or more nuts, bolts, screws, hook and loop fasteners, zippers, clips, clamps, ties, or a combination thereof may be used to attach the protective cover  112  to the base or top of an elevated storage device, a skeleton  508 , or a combination thereof. These fasteners may then be removed to allow the protective cover  112  to be removed and replaced. It will be understood that the base, top, or skeleton  508  of the elevated storage device may include one or more attachment points such as but not limited to threaded or other holes, hooks, loops, or a combination thereof to allow the protective cover  112  to be more easily attached thereto. It will be understood that the protective cover  112  may be attached by fasteners which may not be removable or easily removable such as welds and adhesives in one or more embodiments. 
     In one or more embodiments, an elevated storage device may include a conveyer system to allow for rapid loading and unloading of food items.  FIGS. 6A-6C  illustrate an exemplary embodiment of an elevated storage device including a conveyer system  604 . It will be understood that the elevated storage device may be used with various other conveyer systems  604  in one or more embodiments. 
     As shown, the conveyer system  604  comprises a conveyer belt  608  supported by a plurality of rollers  612 . The conveyer system  604  may be powered by a motor in one or more embodiments. It is contemplated that the elevated storage device may include its own power source to power the motor or that external power may be used such as power from a wall outlet, vehicle, or an engine. Food items may be placed on the conveyer system  604  and moved by the conveyer system toward or away from the elevated storage device. 
       FIGS. 6A-6C  illustrate a conveyer system  604  that may extend and retract. This allows the conveyer system  604  to be stowed away such that it is unobtrusive. This is illustrated by  FIG. 6A  which shows a conveyer system  604  retracted beneath the base  104  of the elevated storage device. The conveyer system  604  may then extend when needed such as shown in  FIG. 6B . 
     It is contemplated that, once extended, the conveyer system  604  may also tilt upwards and downwards relative to the elevated storage device. For example, the conveyer system  604 , or a portion thereof, may be attached to the base of an elevated storage device by a swiveling or rotating hinge type structure. In this manner, the conveyer system  604  may be pointed towards an external object allowing food items to be conveniently loaded and unloaded from various locations outside the elevated storage device. For example, the conveyer system  604  may be rotated towards the bed of a truck or other vehicle. In this way, food items may be easily placed on the conveyer system  604  directly from the truck, or vice versa. 
       FIG. 6C  is a front cross section view of the elevated storage device illustrating exemplary guides  616  attached to the base  104  of an elevated storage device which allow a conveyer system  604  to extend and retract. The guides  616  are generally formed as channels in this embodiment. The conveyer system  604  may include one or more extensions  620  which extend outward from the sides of the conveyer system. It is contemplated that the extensions  620  may extend outward from one or more of the rollers in some embodiments. The extensions  620  may be inserted into the guides  616  as shown in  FIG. 6C . In this manner, the conveyer system  604  may slide along the guides  616  by their extensions  620 . 
     The conveyer system  604  may be extended such as by pulling the conveyer system outward from the elevated storage device along the guides  616 . Once extended, a set of extensions  612  may remain within the guides  616 . In this manner, the conveyer system  604  may rotate about the extensions  612  within the guides  616  to be tilted upwards or downwards if desired. It is contemplated that various mechanisms may be used to allow the conveyer system  604  to extend and retract. In embodiments without a conveyer system  604 , it is contemplated that one or more structures may be provided on the base  104  of the elevated storage device to allow a conveyer system  604  to be conveniently attached. 
     As stated above the elevated storage device provides both storage and transport for food items. It can be seen that the elevated storage device&#39;s protective cover and other components protect food items from external elements thus allowing food items to be safely stored for various periods of time. In one or more embodiments, the elevated storage device allows food items to be stored outside without any additional covering or protection. 
     It is contemplated that a plurality of elevated storage devices may be used to store large quantities of food items. The elevated storage devices may be organized, such as in one or more rows or columns, to allow for convenient access to the food items. This allows the elevated storage devices to provide mobile protected storage to a large quantity of food items. In this manner, a plurality of elevated storage devices may be used instead of more expensive storage apparatuses. For example, a plurality of elevated storage devices may be used instead of a warehouse building or the like. The elevated storage devices may thus provide the benefit of reduced cost. This is especially so when considering that the elevated storage devices may be parked of left outdoors in any lot or area. The elevated storage devices may also be connected to one or more stationary objects by their hitches to prevent them from moving or being moved while storing food items. 
     When needed, food items may be removed from the elevated storage devices, such as by removing or opening their protective covers. Alternatively, the elevated storage devices may be disconnected from any stationary object they may be hitched to and moved to a delivery location where the food items are desired. Once at the desired location the food items may be removed from the elevated storage devices. 
     It can thus be seen that the elevated storage devices also provide the benefit of allowing food items to be quickly moved to other locations. In most cases, the elevated storage device need only be connected to a vehicle, animal, person, or other mechanism and the pulled, pushed, or otherwise moved to the desired location. 
     Referring to  FIG. 1 , the elevated storage device may be used to store and transport food items in various ways. In one embodiment, the protective cover  112  may be opened such as by releasing one or more fasteners. In  FIG. 1 , for example, a hook and loop fastener  120  may be released to open the protective cover. Once open, one or more food items may be placed inside the protective cover  112 . The food items will typically have to be lifted or otherwise moved to the elevated position of the protective cover  112  to allow them to be placed inside the protective cover. As can be seen from  FIG. 5A , food items may be placed on a bottom portion  504  of the protective cover  112  which may be supported or reinforced by the base  104  of the elevated storage device. 
     Once the desired food items have been placed, the protective cover  112  may be closed such as shown in  FIG. 5B . In one or more embodiments, closing the protective cover  112  includes closing or reconnecting one or more fasteners. For example, the fasteners  512  of  FIG. 5B  or the hook and loop fastener  120  of  FIG. 1  may be reconnected to close the protective cover  112 . The elevated storage device may then be left in position or may be moved to deliver the food items. In any case, the elevated storage device protects the food items during storage and transport. When desired, the protective cover  112  may be opened, such as described above, and the food items removed. 
     It is contemplated that the elevated storage device may be used to load and unload food items to and from other vehicles. For example, one or more elevated storage devices may be moved to a train, plane, boat, truck, or other vehicle and the food items in the elevated storage devices may be transferred to these vehicles for further transport. In addition, food items may be transferred from these vehicles to one or more elevated storage devices for safe storage. The elevated storage devices may then be moved to an individual&#39;s or entity&#39;s property or other location if desired while the food items remain protected in the elevated storage device. 
     While various embodiments of the invention have been described, it will be apparent to those of ordinary skill in the art that many more embodiments and implementations are possible that are within the scope of this invention. In addition, the various features, elements, and embodiments described herein may be claimed or combined in any combination or arrangement.
