CROSS-REFERENCE TO RELATED APPLICATIONS 
       [0001]    This application claims benefit of priority of U.S. Provisional Patent Application No. 61/692,130 filed on Aug. 22, 2012, and entitled “METHOD AND APPARATUS TO FORM AN ARTICULATING CONTAINMENT SPACE FOR A MOTOR VEHICLE,” which is hereby incorporated by reference. 
     
    
     TECHNICAL FIELD 
       [0002]    This application is related to motor vehicles. More specifically, this application is related to containment space for motor vehicles. 
       BACKGROUND 
       [0003]    Tool boxes for work trucks, such as pick-up trucks, are a useful device to protect and organize tools, parts, and other goods in the bed of a truck. There are many designs, locations, and configurations of such tool boxes, but conventional tool boxes consume a significant portion of the pick-up bed space rendering the space in the pick-up bed occupied by the tool box space unusable for loading other items. A typical pick-up bed is typically approximately 8 feet long. The addition of a 2 foot wide tool box to the pick-up bed reduces the available space in the bed by 25% or more. One conventional toolbox allows sliding of tool box relative to the pick-up truck, but does not move the tool box below the plane of the pick-up bed floor, thereby obstructing the placement of items in the pick-up bed floor. Other conventional toolboxes are rigidly fixed into a position in the pick-up bed or slide along the plane of the pick-up bed floor. 
         [0004]    Furthermore, the advent of pick-up trucks using large tires or extended suspension systems, known as monster trucks, render the height of a tool box located in the such pick-up beds to be too high above ground for an average person to reach from the ground. This then makes the contents of the tool box difficult to access from the ground. 
       BRIEF SUMMARY 
       [0005]    Embodiments presented below are directed to methods and apparatuses to form an articulating containment structure, having a containment space body, for a motor vehicle that may also enclose a space in the motor vehicle. In certain embodiments, the use of an articulating containment space body for a motor vehicle may also function as an enclosurement of a space on board a motor vehicle, similar to a tailgate on a pick-up truck, sport utility vehicle (SUV), or mini-vans. Certain embodiments of this disclosure may provide an articulating containment space having the functionality of closure of a motor vehicle space similar to a tail gate as well as the added functionality of storing items in the articulating containment space. In one embodiment, the articulation of the containment space body allows the contents of the containment space to remain on the same plane relative to the earth throughout the articulation path. That is, the contents are not rotated and remain parallel to the ground while the containment space is articulated through the path. In one embodiment, the containment space may be a tool box located on a distal end of the bed of a pick-up truck or other vehicle, in which the tool box also functions as the tailgate of the pick-up bed when the tool box is articulated from a lower, or displaced, position to an upper position in the pick-up bed. In certain embodiments, the containment space may contain a variety of items, including but not limited to tailgate party devices and food and drinking items, and/or animal transport spaces. In one embodiment, the articulating containment space may be traded out from a motor vehicle to accommodate many situations, from work to party to hunting. For example, the containment space may include components for operation of the car or other devices, such as battery cells and fuel cells, that may be traded for charged battery cells or fuel cells. 
         [0006]    In certain embodiments, a containment space may articulate up and down from the distal end of a motor vehicle giving access to vehicle while retaining the same plane of orientation for items located in the containment space from the vertical position to the horizontal position. 
         [0007]    In certain embodiments, the end location of a motor vehicle where the closure gate is normally located is provided with a containment space body configured to form an enclosure for the vehicle and a convenient storage space for various items such as tools, beverages, foods, drinks, fuels, batteries, and/or refrigeration devices. This containment space body is not limited to containing tools, but may be used to contain food, drinks, cooking utensils, refrigerators, stoves, ovens, stereo equipment, animals, etc. It is well known to those familiar with the art of “tail gating” that pick-up tail gates are designed from the factory to be easily removable. Many vehicles have conveniently located near the tail gate electrical outlets from the pick-up trucks electrical system that can be connected to the containment space body and articulation device apparatus disclosed herein for operation of articulation methods and other electrical uses of devices incorporated into the containment space body. 
         [0008]    In one embodiment, the containment space may articulate to a position below or above the vehicle&#39;s interior space to allow access to the vehicle&#39;s interior space, such as a pick-up bed or a mini-van trunk. Furthermore, the containment space may articulate in such a manner as to not disrupt the position of items stored inside it. In one embodiment the containment space body articulates through a path such that the containment space body is always level with the earth. In this embodiment during the articulation of the containment space, the storage box may maintain the same plane throughout the articulation, such that materials inside the containment space remain in the same relative position inside the containment space at all points along during the articulation process. 
         [0009]    In certain embodiments, the containment space may be located on the distal end of the motor vehicle and allow access to the containment space body in both the vertical inclination as well as the horizontal inclination through various features of the containment space. For example, a tool box containment space may have a door or hatch on the back face of the distal end allowing for access to the containment space body from standing on the ground. In some embodiments where the motor vehicle is high off the ground the articulation makes this back face hatch accessible once the tool box is lowered on monster type trucks where the bed of the pick-up and tailgate a significantly high off the ground. In other embodiments the contents and items contained by the containment space can be accessed through the top through various features.

The structural images may comprise trademarks, advertisements, signatures, icons, words, emblems, insignia, or ornaments to the articulating containment space. In some embodiments, these attached images are removable and different structural images maybe interchanged, attached, and secured to the containment space. One illustrative example of a structural image attachment means comprises a plate containing the image of an animal on the outward face of the image plate attached to the outward face of a containment space body, in which the plate has on its inner-facing face connected to a bolt that penetrates the containment space body. The bolt attached to the image plate is secured with an attachment means on the inside of the containment space body to functionally connect and maintain the structural images position to the containment space body.

     DETAILED DESCRIPTION 
       [0044]    As used herein, “a” or “an” means one or more. Unless otherwise indicated, the singular contains the plural and the plural contains the singular. Where the disclosure refers to “perforations” it should be understood to mean “one or more perforations.” 
         [0045]    Referring to  FIGS. 1-4 , there is provided containment space body or storage unit  101  coupled to cargo carrying area (or bed)  102  of a motor vehicle  110  of  FIG. 5  (wherein  FIGS. 1-4  are partial view of the back of the motor vehicle  110 ), such as a pick-up truck. Storage unit  101  may be configured to articulate along an arc path to a generally upper docking position shown in  FIG. 4 , in which the containment space body&#39;s bottom aligns generally with the floor of the motor vehicle  110  of  FIG. 5  to enclose cargo carrying area  102 . Access doors may be located on the containment space body  101  to allow access to it from the ground. In one embodiment, storage unit or containment space  101  is a steel tool box configured to contain a variety of tools, parts, electrical devices, as well as other items. 
         [0046]    The dimensions of storage unit  101  can vary as applicable. One factor that can affect the dimensions of storage unit  101  is the dimensions of the particular cargo carrying area to be enclosed and equipped with a storage unit  101  as described herein. In one embodiment, the dimensions of storage unit  101  should generally correspond so its width and height and extend sufficiently to enclose the space of the particular cargo carrying area to adequately provide an enclosed area. The depth of the storage unit  101  can vary depending on the particular containment space required for a variety of purposes. 
         [0047]    Moreover, the storage unit  101  can have a variety of docking positions. For example, a docking station does not necessarily have to configure the outward facing portion of storage unit  101  even with the body of the motor vehicle, thereby reducing the space occupied by the storage unit inside the motor vehicle storage space. Storage unit  101  can be made of any of a variety of durable materials, including plastics, metals, and/or a combination thereof. Furthermore, storage unit  101  can be of any design, such as one or more storage areas, doors, shape, color, etc. Moreover, the containment space body can be of any general geometrical shape, including but not limited to a rectangles, cylinders, attached aerodynamic surfaces, curves, and any combination of shapes and surfaces. 
         [0048]    In  FIG. 1 , storage unit  101  is in a displaced position, where storage unit  101  is at least partially below the plane of the floor of the motor vehicle cargo carrying area  102 . In one embodiment, the use of the storage unit  101  does not inhibit access to the cargo carrying area  102 . Storage unit  101  may further comprise two arms  107  attaching storage unit  101  to cargo carrying area  102 . Arms  107  may be connected to motors, displacement cylinders as well as the storage unit  101  to articulate, preferably electrically, the storage unit  101  from the displaced position in  FIG. 1  into a docking position as shown in  FIG. 4  to enclose cargo carrying area  102 .  FIGS. 2 and 3  show the positions of storage unit  101  and arms  107  during this upward movement. The movement may be viewed sequentially through  FIGS. 1 ,  2 ,  3  and  4  such that the storage unit  101  maintains a horizontal plane parallel to the horizontal plane of the earth during articulation of the storage unit  101 . 
         [0049]    The plane may be maintained through one of many ways known to those familiar with the art of mechanical design. In one embodiment, the storage space may be maintained level and parallel to the earth&#39;s horizon with the connection of arms  107  of the articulation device assembly to storage space  101 . A pivot connection  108  shown on  FIG. 7  may be a connection means used between the arm  107  and the connection on storage space  101 , in which the pivot connection  108  of arms  107  to storage space  101  are located above the center of gravity of the storage unit  101 . By maintaining this horizontal plane of the storage space  101  parallel to the horizontal plane of the earth during the articulation process the storage space containment items are not dumped or spilled about the storage space  101  during articulation. 
         [0050]    As shown in  FIG. 4 , storage unit  101  in the docked position of motor vehicle  110  allows the enclosed space of cargo  102  of motor vehicle  110  to hold various items, during transport or otherwise. In the displaced position shown in  FIG. 1 , storage unit  101  is moved out of the way to provide access to cargo carrying area  102  through the back of motor vehicle  110 . In one embodiment, arms  107  comprise electrical over hydraulic actuator pistons. In other embodiments, arms  107  can comprise a portion of an assembly that assists in the articulation of storage unit  101  as illustrated in  FIGS. 6 ,  7 ,  8 , and  9 . 
         [0051]    One embodiment of the articulation assembly is shown in  FIGS. 6 ,  7 ,  8 , and  9 . The articulation assembly may be located inside a motor vehicle cargo space or outside the motor vehicle. In certain embodiments, the articulation device is connected to the motor vehicle  110  and the containment space body  101 . In one embodiment, storage unit  101  maintains a level position relative to the pick-up bed during the articulation process thereby not causing tools, and other items located therein to substantially move during articulation. Furthermore, arms  107  allow for any adjustment of the level of storage unit  101  as desired. 
         [0052]    Referring to  FIG. 5 , there is provided another illustration of an embodiment of a containment space or tool box. This figure shows a containment space  101  located such that the entire space of the pick-up bed  102  is free of obstruction of the containment space  101 . That is, the top of the storage space  101  is located at least even with or below the bottom of the cargo space  102  floor.  FIG. 5  further shows the containment space connected to the electrical power of the truck bed  103 .  FIG. 5  further shows the containment space  101  being articulated upward to a position shown at  104 , wherein the containment space forms an enclosurement of the pick-up bed  102  of motor vehicle  110 .  FIG. 5  further shows a containment space  101  that is removed from the attachments of the pick-up bed  102 , such that a normal tailgate supplied from the pick-up truck manufacture can be returned, or indeed an different containment space can be easily engaged by the articulation assembly such that a containment space body can be configured and or function as a tool box  101  containing tools, a party gate  101  containing food, utensils, beverages, refrigeration, audio and acoustical devices, cooking, and other devices can be supplied in a different articulation containment space body  101  system, allowing the space  106 , at the distal end of the pick-up truck to be used for a plurality of containment space bodies  101 , each having different functions. 
         [0053]    Turning now to  FIGS. 6 ,  7 ,  8 , and  9 , a disclosure of one embodiment of an articulating device assembly is illustrated.  FIG. 6  illustrates a motor vehicle  110 , having a cargo space  102  with a containment space body  101  docked in the storage position inside the storage space  102 .  FIG. 7  is a view from looking back into the storage are  102  of  FIG. 6 , in which  FIG. 7  shows one embodiment of an articulating device assembly located outside the storage area  102 . The articulating device assembly of this embodiment comprises an electrical motor  109 , attached to a gear reduction mechanism  112 , which is attached to a worm gear device  113 , which is attached to a shaft  114 . The shaft  114  runs parallel to the width of the containment space  101  and the shaft  114  is attached and fixed to the two lifting arms  107  located on either side of the containment space body  110 . A pivot assembly  108  may be connected to the containment space  101  on both sides, which is where the articulating arms  107  may attach to the containment space  101 . 
         [0054]      FIG. 7  further illustrates the two lifting arms  107  connected with rotating balls inside the two respective pivot socket connection devices  108  on either side of the containment space body  101 . Then, by powering the electrical motor  109  to turn the gears  112  and  113 , the shaft  114  is rotated, thereby pulling the two lifting arms  107  causing the containment space body  101  to articulate out from the motor vehicle cargo space  102 . The containment space body  101  is thus allowed to rotate within the pivot socket  108  using ball devices attached to lifting arms  107  allowing the containment space body to remain parallel with the earth&#39;s horizon during articulation thereby not dislodging items stored in the containment space body.  FIG. 8  shows the containment space body  101  articulated out below the motor vehicle cargo space  102  thereby allowing full access to the motor vehicle cargo space  102 .  FIG. 9  is a view from the rear of motor vehicle  110  looking forward into the motor vehicle cargo space  102 , in which the containment space body  101  has been articulated out and below of the vehicle cargo space  102 . 
         [0055]    In one embodiment, the containment space described above may be used with pick-up bed closure covers, such as those manufactured by Tonneau Covers of Ocala Fla., such that a pick-up may maintain the functionality of a pick-up bed closure cover while also having access to the articulating tool box  101  shown  FIG. 5 . Therefore, availability and access to the contents of the containment space  101  tool box may be provided through doors  111  shown on  FIG. 5  without opening the pick-up cover devices. 
         [0056]    Although the above discussion discloses the use of the containment space body  101  for tools, parts, food stuffs, entertainment devices, it is understood that the containment space body  101  can contain batteries to form a large battery storage system, contain liquid fuels like natural gas, cryogenic fluids like liquid natural gas, to power the motor vehicle  110 , and any other forms of matter including, but not limited to, cameras, position sensors, audio speakers, display screens, etc. The containment space body  101  and articulation device assembly can then be used to quickly unload and disengage a fuel source containment space body  101 , such as a large battery pack, and quickly engage a fully-charged new containment space body battery pack and articulated it to the docking position shown in  FIG. 4 . This battery pack can then be plugged into the power system of the motor vehicle  110  at a position as shown in  FIG. 5  to then power an electrical motor of motor vehicle  110  or removed as shown in position  105  to be charged while another containment space body battery pack is engaged and loaded into the motor vehicle docking position with the articulation device assembly. 
         [0057]    Although the present disclosure and its advantages have been described in detail, it should be understood that various changes, substitutions and alterations can be made herein without departing from the spirit and scope of the invention as defined by the appended claims.
