20140034637
The technology described herein generally relates to receptacles, such as modular cargo containers, and more particularly, to a storage, or cargo, module adapter assembly for modular cargo containers.
In recent years, the United States military establishment has rediscovered the importance of being able to safely and efficiently deploy equipment and supplies during foreign expeditions. In particular, the military establishment has realized the benefits of being able to transport and store supplies for units of decreasing size, for example, at the platoon or even squad level.
For hazardous materials, U.S. Pat. No. 4,875,595 issued on Oct. 24, 1989 to Van Valkenburgh discloses a storage enclosure having a containment pan supported on a base frame to allow for visual inspection of the underside of the pan. U.S. Pat. No. 5,356,206 issued on Oct. 18, 1994, also to Van Valkenburgh, discloses another hazardous material storage enclosure with secondary containment shelves that are suspended from a sub-roof assembly.
U.S. Statutory Invention Registration H1477 issued on Sep. 5, 1995 to Payne discloses a mobile containment structure having a plurality of modular shelving units bolted to the floor of the structure for housing and storing cans of paint, drums of lubricant, and the like. U.S. Pat. No. 5,511,908 issued on Apr. 30, 1996 to Van Valkenburgh et al. discloses another mobile safety structure having a removable and grated floor which allows access to a containment pan underneath the floor. U.S. Pat. No. 5,735,739, issued to Payne et al. on Apr. 7, 1998, discloses another mobile safety structure formed by tandem and/or stacked modular units. Finally, U.S. Pat. No. 5,785,591 issued on Jul. 28, 1998 to Payne discloses yet another mobile safety structure with five compartments that are separated by fire-proof walls.
In addition to hazardous materials transport systems, a wide variety of other logistical support systems are now containerized in order to speed troop deployments. As shown in the patents noted above, the military uses a wide variety of specialized containers to not only transport various cargoes in compliance with national and international requirements, but also to store and secure this equipment in the theater of operations. Higher readiness requirements and more limited opportunities for the pre-positioning of military supplies in foreign countries also mean that many military units must store at least some of their supplies in these containers while they are stationed at home between deployments. Since this cargo is often pre-packaged into conventional cardboard boxes which are then stacked side-to-side in end-loaded containers, the entire cargo must often be removed from the container and the boxes in order to locate just one particular item. The leftover boxes must then be collected and disposed of, or recycled, before the container can be reloaded with the remaining stores.
These and other logistical problems can be particularly troublesome for bulk items or “small stores.” In this regard, U.S. Pat. No. 4,860,913 to Bertolini discloses a cargo container fitted with a plurality of steel storage cabinets which are integrated into the structure of the container so as to maintain their position and shape when the container is subject to external forces during transportation. In particular, the cabinets are bolted to the side walls of the container, and to each other, with an aisle between them so that articles inside the cabinets can be accessed only by entering through doors at one end of the container, and then opening a particular drawer into the aisle. The cabinet drawers cannot be accessed from outside the container, nor can the cabinets be easily switched from one container to the next.
Each of U.S. Pat. No. 6,299,008, issued to Payne on Oct. 9, 2001, and U.S. Pat. No. 7,185,779, issued to Payne on Mar. 6, 2007, disclose various embodiments of a transport and storage system having removable and interchangeable storage modules for use with a transport and storage device in the form of a standard size (8 foot wide by 8 foot high by 20 foot long ISO) freight container.
The subject matter of each of the patents discussed above is hereby incorporated by reference into the present disclosure.
A problem arises when it is desired to use the above discussed storage modules, which are typically designed for use with specific freight containers, with modular cargo containers, such as tricon or quadcon containers. Such modular cargo containers are designed to have dimensions, such that, when the modular cargo containers are combined (for example, in sets of three or four) the combined modular cargo containers have the same exterior dimensions as a standard size freight container.
There is currently a glut of such modular cargo containers in the world marketplace, but the usefulness thereof is diminished due to the still relatively large interior size of such modular cargo containers. For example, a tricon container will have exterior dimensions of 8 foot wide by 8 foot high by 6 foot 5.5 inches long. Such modular cargo containers are not convenient for storage of smaller, bulk items of cargo, such as, for example, personal equipment.
Given the large number of existing modular cargo containers, and the prohibitive cost of designing and producing replacement containers, there is a need to adapt existing modular cargo containers for use with existing and after developed storage modules without substantial alteration of the structure of the existing modular cargo containers.
In view of the above discussion, an embodiment of a storage module adapter assembly for securing a storage module to a support surface, such as modular cargo containers, is disclosed.
In use, the disclosed storage module adapter assembly provides an interface between a modular cargo container and a storage module.
The storage module adapter assembly includes adapter base plates that are two-person portable, can be installed/removed by hand, cooperate with existing structures of existing modular cargo containers, and can be installed without alteration of the existing modular cargo containers to be anchored relative thereto, for example, there is no drilling into or welding to the existing structures of existing modular cargo containers.
Each adapter base plate includes various longitudinal and transverse frame members, as well as first and second longitudinal frame members on opposed sides thereof. The first longitudinal frame member has a first height, and the second longitudinal frame member has a second height, which is greater than the first height. Each of the first and second longitudinal frame members also include generally horizontal flange members extending from a top side thereof, such that when two adapter base plates are appropriately positioned side by side, the generally horizontal flange members on the adjacent sides of the two adapter base plates overlap in a nested relationship due to the difference between the first and second heights.
The adapter base plates can then be connected together by appropriate mechanisms, along with two additional adapter base plates, in order to form the storage module adapter assembly. The overlapping nested relationship of the generally horizontal flange members provides a structure along the center of the storage module adapter assembly, when assembled, that provides a solid reinforcement to prevent shifting of storage modules anchored thereto, in particular vertical shifting, under heavy loading conditions.
Once the storage module adapter assembly is assembled together from the adapter base plates, the storage module adapter assembly can be anchored relative to the modular cargo container in which it is positioned, and one or more storage modules can be anchored to the storage module adapter assembly. In this manner, storage modules can be anchored relative to the modular cargo container to prevent vertical and horizontal translation or rotation of the storage modules with respect to both the storage module adapter assembly and the modular cargo container.
These and other features, aspects, and advantages of the present invention will become better understood with regard to the following description, appended claims, and accompanying drawings where:
It should be noted that the drawing figures are not necessarily drawn to scale, but instead are drawn to provide a better understanding of the components thereof, and are not intended to be limiting in scope, but rather to provide exemplary illustrations. It should further be noted that the figures illustrate exemplary embodiments of a storage module adapter assembly and the components thereof, and in no way limit the structures or configurations of a storage module adapter assembly and components thereof according to the present disclosure.
The use of a storage module adapter assembly for a support surface, such as in a module container or freight container, according to the present disclosure is generally shown in
The exemplary modular cargo container 10 includes two opposed open sides that can be selectively closed off by the use of hinged doors 24. As shown, a pair of double doors 24 are connected to the modular cargo container 10, and are swingable between open and closed positions. A door latching mechanism 26 is provided, which can allow the doors to be selectively locked in the closed position. It will be recognized that a modular cargo container having only one open side closed off by the use of hinged doors could also be provided.
Forklift pockets 16 are provided at the bottom portion of the frame of the modular cargo container 10 to allow the blades of a forklift to pass therethrough for lifting and lowering of the modular cargo container 10.
As shown in
As shown in
The storage modules 30 can be in the form of cabinets. Such cabinets may be arranged with their drawers, shelves, and/or racks opening toward the doors 24 of the modular cargo container 10 for easy access, or with their drawers opening toward the inside of the container for limited access and better security.
While the storage modules 30 are generally shown in
The storage modules 30 allow various types of cargo to be segregated within the modular cargo container 10. Cargo can also be further segregated in the drawers or shelves of any one particular storage module 30 and/or by dividers inside those drawers. Furthermore the storage modules 30 may be designed to hold a particular type and/or size of cargo. For example, certain storage modules 30 may be used to contain hazardous materials or bulky items while other storage modules contain non-hazardous materials or less bulky items.

The adapter plate 52 also includes a first longitudinal frame member 60 having a first height, for example 5.0625 inches, central longitudinal frame members 62 (of the same general form as the transverse frame members 54, 56), and a second longitudinal frame member 64 having a second height that is greater than the first height, for example 5.5 inches. The first and second longitudinal frame members 60, 64 are formed as generally plate shaped members, but can take any suitable form.
Generally horizontal flange members 68 extend from the top sides of the first and second longitudinal frame members 60, 64. As will be discussed in detail below, when the adapter plates 52 are assembled together to form the storage module adapter assembly 50, the adjacent horizontal flange members 68 of the respective adapter plates 52 overlap each other in a nested relationship so that the adapter plates 52 can be connected together.
As shown in
Additionally, each of the vertical transverse flange members 58 and each of the first and second longitudinal frame members 60, 64 have various openings 70, which provide hand holds and/or access to bolt heads for connecting the adapter plates 52 together, as well as connection openings 72 to allow the passage of connection members, such as bolts 96.

As shown in
The method of assembling the adapter plates 52 into the storage module adapter assembly 50 shown in
Next, a second adapter plate is positioned adjacent to the first adapter plate, with the second longitudinal frame member 64 thereof aligned adjacent to the first longitudinal frame member 60 of the first adapter plate, so that the generally horizontal flange member 68 of the second longitudinal frame member 64 of the first adapter plate extends over the generally horizontal flange member 68 of the first longitudinal frame member 60 of the second adapter plate, such that the connection openings 74 in the generally horizontal flange members 68 are aligned.
As best seen in
This process is repeated with third and fourth adapter plates, which are positioned within the modular cargo container 10, as discussed above with respect to the first and second adapter plates, and adjacent to the first and second adapter plates. The overlapping, nested, generally horizontal flange members 68 provide a solid reinforcing structure along the center of the storage module adapter assembly 50 that prevents shifting of storage modules 30 connected thereto, in particular, vertical shifting under heavy loading.
Once the third and fourth adapter plates are connected together, using the same process discussed above, they can be further connected to the first and second adapter plates.
In particular, as shown in
Alternatively, the third and fourth adapter plates can first be connected to the respective first and second adapter plates, and subsequently connected to each other, in the manners discussed above.
Once the adapter assembly 50 has been assembled within the modular cargo container 10, the adapter assembly 50 can be anchored from vertical or horizontal translation or rotation relative to the modular cargo container 10 using any suitable mechanism that does not alter the existing structure of the modular cargo container 10.
For example, as shown in
In a variation shown in
After the adapter assembly 50 has been anchored from vertical or horizontal translation or rotation relative to the modular cargo container 10, for example, by utilizing anchor members 102, the pressure applying bolts 96 shown in
After the assembly 50 has been assembled and anchored, each pressure applying bolt 96, as shown in
Once the adapter assembly 50 has been anchored from vertical or horizontal translation or rotation relative to the modular cargo container 10, for example, anchored relative to the floor of the modular cargo container 10, the storage modules 30 can be placed into the modular cargo container 10, and anchored thereto.
To accomplish the anchoring of the storage modules 30, as shown in
The centrally positioned module securing assembly 76 corresponds to the centrally positioned module bracket 40 on the bottom of the storage modules 30. The module securing assembly 76 includes an adapter bracket 78, having arm notches 80 formed at two sides thereof, and an adapter securing fitting 82 passing through the adapter bracket 78. An arm 84 is connected to operate the adapter securing fitting 82. A grab handle 88 is operatively connected to the arm 84 at nub 86, and is supported by the grab handle support 90 for manipulation by an operator to anchor the storage modules 30 to the adapter plate 52. The arm notches 80 accommodate the rotational movement of the arm 84.
Suitable adapter securing fittings are available from Tandem Lock, Inc., of Havelock, N.C. Tandem Lock's straight handle twist lock steel, painted, Part No. S38000B-1 PA is illustrated in the figures; however a variety of other securing fittings may also be used. Various other quick-release securing mechanisms could also be used with appropriate modification of the brackets disclosed here. The adapter securing fitting 82 may also be provided with a locking mechanism
As discussed above, the module bracket 40 includes an elliptical opening 42 for receiving the corresponding top portion of the adapter securing fitting 82 when the storage module 30 is being anchored. The module bracket 40 may also be replaced by an elliptical opening in the base of the storage modules 30 by shortening the projections 34 on the storage modules 30 and/or raising the height of the adapter bracket 78.
In operation of the adapter securing or clamping fitting 82 for releasably securing the bracket 40 on the storage module 30 to the corresponding bracket 78 on the adapter plate 52, the projections, or feet, 34 of the storage module 30 have already been lowered into the receptacles 92 using a forklift with forks extending through forklift safe zones or pockets 38. As previously discussed, the arm 84 on the adapter clamping fitting 82 may be easily rotated with the aid of a grab handle 88 which engages a nub 86, or other portion of the arm 84, so as to create an easily accessible extension for the arm 84. Rotation of the arm 84 on the adapter clamping fitting 82 causes the head of the adapter clamping fitting to first move vertically through the elliptical hole 42 in the module bracket 40. Once the adapter clamping fitting 82 is fully extended through the elliptical hole 42, further rotation of the arm 84 causes the head of the fitting 82 to rotate and then to retract so that the bottom side of the head abuts the inside surface of the module bracket 40 and clamps the storage module 30 to the corresponding adapter bracket 78 on the adapter 52.
This process is repeated for each storage module 30 to anchor and secure the storage modules to the modular cargo container 10, via the storage module adapter assembly 50. If a single, larger storage module is to be used, such that the size of the storage module is such that more than one adapter plate 52 is encompassed by the storage module, appropriate module brackets 40 can be positioned on the larger storage module for cooperation with each of the adapter securing fittings 82 of the respective adapter plates 52.
In order to remove a storage module 30 from the modular cargo container 10, the process can be reversed to release the module bracket 40 from being secured with the adapter bracket 78, so that the storage module 30 can be lifted from the adapter plate 52 and removed from the modular cargo container 10.
Accordingly, in view of the above discussion, storage modules can be used with existing modular cargo containers, by utilizing the above described storage, or cargo, module adapter assembly. The storage module adapter assembly is conveniently manipulated and assembled by two persons, so that heavy equipment or special tools are not required. Further, the storage module adapter assembly can be anchored to existing modular cargo containers, in order to secure storage modules therein, without the need to modify the existing modular cargo containers, for example, by drilling or welding.
It will be recognized that the storage, or cargo, module adapter assembly and components thereof can be made from any suitable materials, such as cold-rolled steel panels, corrosion-resistant steel, aluminum and other metals, and plastic, fiberglass, wood, and/or composite materials. It will also be recognized that the storage, or cargo, module adapter assembly and components thereof can be made to have any suitable size, for example, to be used with different sized modular cargo containers.
While the discussion above details assembling the storage module adapter assembly within the modular cargo container, it will be recognized that the storage module adapter assembly can be assembled outside of the modular cargo container and subsequently lifted into place. The advantage of assembling the storage module adapter assembly within the modular cargo container is that each adapter plate is sufficiently lightweight so that the adapter plates can be manipulated by two persons, thus, providing easier assembly.
Additionally, while the method of assembling the storage module adapter assembly discussed above includes placing the first adapter plate within the modular cargo container with the second longitudinal frame member adjacent to the side panel of the modular cargo container, it will be recognized that the process can be adapted to begin with placing the first adapter plate within the modular cargo container with the first longitudinal frame member adjacent to the side panel of the modular cargo container.
