The present disclosure relates generally to cargo containers, and more particularly, to hybrid cargo container systems for use with both ground transportation vehicles and air transportation vehicles.
Existing cargo containers used for intermodal transport are typically cuboid-shaped. Although such containers can be easily stacked, they are not ideal for use on aircraft, which typically have rounded cross-sections. As such, some existing cargo containers are designed with a chamfered corner in their cross-sections to better utilize the available space in aircrafts.
However, existing chamfered cargo containers are typically unable to be stacked on each other, due to corners being necessary for providing the required support. In addition, stacking and storage of such chamfered containers typically requires specialized racks. Furthermore, such chamfered containers are typically only used for the airborne leg of a journey, which can incur undesired costs and inefficiencies in the packing and unpacking of goods to and from such containers, as opposed to keeping goods in the same container for multiple legs of a journey.
Thus, what is needed is a cargo container that is less costly and more efficient for use with intermodal travel involving an aircraft.
In an example, a hybrid cargo container system for use with ground transportation vehicles and air transportation vehicles is disclosed. The hybrid cargo container system includes a chamfered container body comprising a plurality of sidewalls defining a storage chamber, the plurality of sidewalls comprising a first sidewall, a second sidewall, and a chamfer sidewall attached to the first sidewall and the second sidewall. The hybrid cargo container system also includes a corner support assembly operably coupled to the chamfered container body, where the corner support assembly is operable between a stowed position and a deployed position, where based on the corner support assembly being in the deployed position, the corner support assembly is configured to at least partially support another container stacked thereon for ground transportation, and where based on the corner support assembly being in the stowed position, the hybrid cargo container system is configured to be stored in a fuselage of an aircraft for air transportation.
In another example, another hybrid cargo container system for use with ground transportation vehicles and air transportation vehicles is disclosed. The hybrid cargo container system includes a chamfered container body comprising a plurality of sidewalls defining a storage chamber, the plurality of sidewalls comprising a first sidewall that defines a first plane, a second sidewall that defines a second plane transverse to the first plane, and a chamfer sidewall that defines a chamfer plane that is non-orthogonal relative to the first plane and the second plane. The hybrid cargo container system also includes a corner support assembly removably coupled to the chamfered container body, where based on the corner support assembly being coupled to the chamfered container body, the hybrid cargo container system defines a first planar support region and is configured to at least partially support another container stacked thereon for ground transportation, and where based on the corner support assembly being removed from the chamfered container body, the hybrid cargo container system defines a second planar support region, smaller than the first planar support region, and is configured to be stored in a fuselage of an aircraft for air transportation.
In yet another example, a method is disclosed. The method includes moving a corner support assembly of a hybrid cargo container system from a deployed position to a stowed position, where based on the corner support assembly being in the deployed position, the corner support assembly is configured to at least partially support another container stacked thereon. The method also includes loading the hybrid cargo container system into a fuselage of an aircraft based on the corner support assembly being in the stowed position.
In yet another example, a hybrid cargo container system is disclosed. The hybrid cargo container system includes a chamfered container body comprising a plurality of sidewalls defining a storage chamber, the plurality of sidewalls comprising a pair of lateral sidewalls, a pair of longitudinal sidewalls longer than the pair of lateral sidewalls, an upper sidewall, a lower sidewall, and a chamfer sidewall that is attached to, and extends transverse between, the upper sidewall and one longitudinal sidewall of the pair of longitudinal sidewalls. The hybrid cargo container system also includes a pair of supports pivotably coupled to opposite ends of the one longitudinal sidewall or to the pair of lateral sidewalls, where the pair of supports are rotatable between a stowed position and a deployed position, where based on the pair of supports being in the deployed position, the hybrid cargo container system defines a first volume and is configured to at least partially support another container stacked thereon, and where based on the pair of supports being in the stowed position, the hybrid cargo container system defines a second volume that is less than the first volume
The features, functions, and advantages that have been discussed can be achieved independently in various examples or may be combined in yet other examples. Further details of the examples can be seen with reference to the following description and drawings.
The novel features believed characteristic of the illustrative examples are set forth in the appended claims. The illustrative examples, however, as well as a preferred mode of use, further objectives and descriptions thereof, will best be understood by reference to the following detailed description of an illustrative example of the present disclosure when read in conjunction with the accompanying drawings, wherein:
Disclosed examples will now be described more fully hereinafter with reference to the accompanying drawings, in which some, but not all of the disclosed examples are shown. Indeed, several different examples may be described and should not be construed as limited to the examples set forth herein. Rather, these examples are described so that this disclosure will be thorough and complete and will fully convey the scope of the disclosure to those skilled in the art.
Unless otherwise specifically noted, elements depicted in the drawings are not necessarily drawn to scale.
Within examples, described herein are hybrid cargo container systems and a corresponding method for use with ground transportation vehicles and air transportation vehicles.
The disclosed hybrid cargo container system includes a chamfered container body having a plurality of sidewalls defining a storage chamber for cargo, the plurality of sidewalls including a first sidewall, a second sidewall, and a chamfer sidewall attached to the first sidewall and the second sidewall. Within examples, the chamfered container body is prism-shaped with a pentagonal cross section. The chamfer in the container body can allow for the hybrid cargo container system to be stored in an aircraft or other location having a curved sidewall that would otherwise be incompatible with typical container corners.
The disclosed hybrid cargo container system also includes a corner support assembly operably coupled to the chamfered container body. The corner support assembly is operable between a stowed position and a deployed position, such that, with the corner support assembly in the deployed position, the corner support assembly is configured to at least partially support another container stacked thereon for ground transportation, and with the corner support assembly being in the stowed position, the hybrid cargo container system is configured to be stored in a fuselage of an aircraft for air transportation.
Accordingly, the hybrid cargo container system can be efficiently transferred between ground and air transportation by transitioning the corner support assembly between the stowed and deployed positions.
These and other improvements are described in more detail below. Implementations described below are for purposes of example. The implementations described below, as well as other implementations, may provide other improvements as well.
Referring now to the figures,
The hybrid cargo container system 100 includes a chamfered container body 102 and a corner support assembly 104. The chamfered container body 102 has a plurality of sidewalls 106, which includes a first sidewall 108, a second sidewall 110, and a chamfer sidewall 112 attached to the first sidewall 108 and the second sidewall 110. The plurality of sidewalls 106 define a storage chamber within which cargo can be disposed.
As discussed in more detail below, the corner support assembly 104 is operably coupled to the chamfered container body 102 and used to facilitate storage of the hybrid cargo container system 100 in both aircraft and ground transportation vehicles, representative examples of which are depicted in
As noted above, for example, the corner support assembly 104 is operable between a stowed position and a deployed position. Based on the corner support assembly 104 being in the deployed position, the corner support assembly 104 is configured to at least partially support another container (not shown) stacked thereon for ground transportation, such as when the hybrid cargo container system 100 is storage on or in the ground transportation vehicle 116 (e.g., on a truck bed). And based on the corner support assembly 104 being in the stowed position, the hybrid cargo container system 100 is configured to be stored in the aircraft 114 (e.g., a fuselage of the aircraft 114) for air transportation.
In some cases, the hybrid cargo container system 100 can be positioned upside-down such that the chamfer sidewall 112 is facing a ground surface. When the hybrid cargo container system 100 is positioned in this way and the corner support assembly 104 is in the deployed position, the hybrid cargo container system 100 can be stacked on another container in this way as well, and can also support another container stacked thereon.
The aircraft 114 can take the form of various types of aircraft, such as commercial or non-commercial aircraft. The ground transportation vehicle 116 can take various forms as well, such as a truck.
The corner support assembly 104 can be operably coupled to the chamfered container body 102 in various ways. For example, the corner support assembly 104 is rotatably coupled by way of a pivot or other mechanism. As another example the corner support assembly 104 is removably fastened to one or more of the plurality of sidewalls 106 of the chamfered container body 102, such as by way of one or more bolts, screws, etc. As yet another example, the corner support assembly 104 is manufactured to be integral with one or more of the plurality of sidewalls 106. Other examples are possible as well.
As shown, the plurality of sidewalls 106 (not explicitly designated in
Within examples, the pair of longitudinal sidewalls 124 can be longer than, approximately the same length as, or shorter than, the pair of lateral sidewalls 122.
As further shown, the first sidewall 108 (i.e., the upper sidewall 118) defines a first plane 126, the second sidewall 110 defines a second plane 128 transverse to the first plane 126, and the chamfer sidewall 112 defines a chamfer plane 130 that is non-orthogonal relative to the first plane 126 and the second plane 128.
Also shown in
In particular,
As shown, the pair of supports 134 are rotatable between the stowed position and the deployed position. In some cases, a human operator can manually rotate each of the pair of supports 134 individually. In other cases, the pair of supports 134 can be rotatable via an electromechanical, pneumatic, or hydraulic mechanism. For reference,
Although not explicitly shown in
As further shown, the pair of supports include corner fittings 135. The corner fittings 135 can be made of steel, carbon, or another material, and can be configured to (i) connect the hybrid cargo container system 100 to another container, such as another such system or another type of container (e.g., an un-chamfered, cuboid-shaped container) and (ii) connect the hybrid cargo container system 100 to a transport vehicle such as the aircraft 114, the ground transportation vehicle 116, or another type of vehicle (e.g., a watercraft). Further, although not explicitly shown in
Based on the pair of supports 134 being in the deployed position, the hybrid cargo container system 100 defines a first volume 136 and is configured to at least partially support another container stacked thereon (not shown). Phrased another way, with the corner support assembly 104 in the deployed position, the hybrid cargo container system 100—namely, the upper sidewall 118 and the pair of supports 134—define(s) a first planar support region 138 configured to at least partially support another container stacked thereon for ground transportation. For illustrative purposes, the first volume 136 is shown to be larger than the actual volume that the hybrid cargo container system 100 occupies in space when in the deployed position.
As further shown, based on the corner support assembly 104 being in the deployed position, the corner support assembly 104 extends into the corner space 132 that is exterior to and adjacent to the chamfer sidewall 112.
In embodiments where the corner support assembly 104 is removably coupled to the chamfered container body 102 and based on the corner support assembly 104 being coupled to the chamfered container body 102, the corner support assembly 104 can occupy at least a portion of the corner space 132 and the hybrid cargo container system defines the first planar support region 138 and is configured to at least partially support another container stacked thereon for ground transportation. Whereas, based on the corner support assembly 104 being decoupled and removed from the chamfered container body 102, the corner support assembly 104 will not occupy any portion of the corner space 132, or will occupy less of the corner space 132 than when the corner support assembly 104 is attached to the chamfered container body 102, and the hybrid cargo container system 100 defines a second planar support region (not shown in
As further shown, based on the corner support assembly 104 being in the stowed position, the corner support assembly 104 is retracted toward the chamfer sidewall 112 and occupies less of the corner space 132 than when in the deployed position.
Although not explicitly shown, in some examples the corner support assembly 104 can include a plurality of posts having more than two posts, such as a pair of posts coupled to the pair of lateral sidewalls 122 and a third post coupled to the second sidewall 110.
The corner support assembly 104 also includes a pair of additional members 168 that can slide back and forth parallel to the x-axis (e.g., along a track (not shown) disposed on an exterior surface of the chamfer sidewall 112) and are configured to provide additional support and help reduce or prevent bending of the pair of posts 152 in the y-direction. In alternative examples, the pair of additional members 168 are not included.
In addition, the corner support assembly 104 also includes (i) a first torsion member 170 extending longitudinally between the proximal ends 160 and (ii) a second torsion member 172 extending longitudinally between the pair of hinged members 154, each torsion member being configured to cause substantially simultaneous actuation of the pair of posts 152 between the deployed position and the stowed position. In alternative examples, the first torsion member 170 and/or the second torsion member 172 is/are not included.
Still further, the corner support assembly 104 includes a side brace actuation lever 174 and a corner post actuation lever 176 for actuating the pair of posts 152 between the deployed position and the stowed position.
To further illustrate movement of the pair of posts 152 between the deployed and stowed positions,
More particularly, to move the pair of posts 152 from the deployed position to the stowed position, the side brace actuation lever 174 and the corner post actuation lever 176 are detached/decoupled from a first pair of securing mechanisms 178 (e.g., latches, detents, plungers, etc.) and rotated to the intermediate position in the direction shown by the arrows. This causes the pair of hinged members 154 to bend as shown, after which the side brace actuation lever 174 and the corner post actuation lever 176 can be moved from the intermediate position to the stowed position in the direction shown by the arrows. The side brace actuation lever 174 and the corner post actuation lever 176 are then attached/coupled to a second pair of securing mechanisms 180 (e.g., latches, detents, plungers, etc.), thus securing the pair of posts 152 in the stowed position.
The pair of threaded screw jack sleeves 186 can be disposed in and attached to existing cavities present in the chamfered container body 102, or can be integral with the chamfered container body 102, while conforming with typical standards for intermodal containers, for instance. Within examples in which a high-friction system is used (e.g., not a ball screw) for the pair of threaded screw jack sleeves 186, the screw jack mechanism for actuating the pair of supports 182 cannot be driven under load and/or high vibration, thus helping to increase safety and reliability in both the stowed and deployed positions.
In some cases, the corner support assembly 104 also includes a drive shaft 188 extending longitudinally between the pair of threaded screw jack sleeves 186 and configured to cause substantially simultaneous actuation of the pair of supports 182 between the deployed position and the stowed position. The drive shaft 188 can be driven from either end by hand, with a power hand tool (e.g. cordless electric screwdriver), or by internal power and actuators, for example.
In particular,
Accordingly,
In particular,
In addition, corner fittings 226, such as those configured as described above with respect to aforementioned Figures, can be coupled to each corner of the hybrid cargo container system 100.
As further shown, the hybrid cargo container system 100 defines a first planar support region 228 based on the frame 224 being coupled to the chamfered container body 102, and would define a second planar support region 230 based on the frame 224 being removed from the chamfered container body 102.

At block 302, the method 300 includes moving a corner support assembly of a hybrid cargo container system from a deployed position to a stowed position, where based on the corner support assembly being in the deployed position, the corner support assembly is configured to at least partially support another container stacked thereon.
At block 304, the method 300 includes loading the hybrid cargo container system into a fuselage of an aircraft based on the corner support assembly being in the stowed position.
In some embodiments, moving the corner support assembly from the deployed position to the stowed position involves moving the corner support assembly from the deployed position to the stowed position to cause the hybrid cargo container system to define less of a volume in the stowed position than when in the deployed position.
In some embodiments, moving the corner support assembly of the hybrid cargo container system from the deployed position to the stowed position involves moving a corner support assembly that is coupled to at least one sidewall of a plurality of sidewalls of a chamfered container body of the hybrid cargo container system, the plurality of sidewalls define a storage chamber for storing and transporting items therein, and the plurality of sidewalls comprises a first sidewall, a second sidewall, and a chamfer sidewall that is attached to, and extends transverse to, the first sidewall and the second sidewall. Further, in such embodiments, moving the corner support assembly from the deployed position to the stowed position involves moving the corner support assembly from the deployed position to the stowed position to cause the corner support assembly to occupy less of a corner space exterior to and adjacent to the chamfer sidewall than when in the deployed position. Additionally, in such embodiments, loading the hybrid cargo container system into the fuselage of the aircraft based on the corner support assembly being in the stowed position comprises loading the hybrid cargo container system into the fuselage of the aircraft such that a curved sidewall of the fuselage occupies at least a portion of the corner space.
