DETAILED DESCRIPTION

Various aspects of the present disclosure are directed toward expandable containers, and more specifically to an expandable field kitchen. With respect to containers in general, a container can be a permanently assembled structure, or the container can be readily assembled/disassembled. For instance, a container can be disassembled into component parts for ease of transportation and then deployed in the field (e.g., at a suitable location) back into a container.

In this regard, the assembled container can function as a storage unit, as a housing unit, shelter, or for any other reasonable purpose. In some embodiments, the container can be assembled such that all necessary parts are integrated into the container panels or are otherwise incorporated therewith, which reduces or eliminates a risk for losing parts necessary to assemble or deploy the container.

Modern intermodal shipping containers are capable of being transported by various modes including land, rail, sea and air and come in various standard sizes as specified by International Standards Organization specifications such as ISO 668. The standardization of shipping container dimensions and other characteristics allow efficient handling, storage, transportation and logistical operations across the globe and contributes to the growth of global trade.

By way of illustration, some shipping containers in commercial service are 8 ft (feet) wide, 40 ft long and 8 ft 6 inches high (or ˜2.43 m (meters) wide, ˜12.20 m long, and ˜2.60 m high) and 8 ft wide, 20 ft long and 8 ft 6 inches high (or ˜2.43 m wide, ˜6.10 m long, and ˜2.60 m high). In some instances, the shipping containers can be 9 ft 6 inches (˜2.90 m) high.

Another standard size that is often used by the U.S. military includes 8 ft wide, 10 ft long and 8 ft high (or ˜2.43 m wide, ˜12.20 m long, and ˜2.60 m high), which may be referred to as a “Bicon”. Containers that are 8 ft wide, 6 ft 6 inches long and 8 ft high (or ˜2.43 m wide, ˜2.00 m long, and ˜2.43 m high) are generally referred to as “Tricon”, and 8 ft wide, 4 ft 10 inches long and 6 ft 10 inches (or ˜2.43 m wide, ˜1.47 m long, and ˜2.09 m high) for a “Quadcon”.

Two Bicons can be connected with special connectors at the top and bottom corners to form a 20 ft long container.

Similarly, three Tricons and four Quadcons can be connected to form a 20 ft long container. Thus, the Bicons, Tricons and Quadcons, when connected as 20 ft units, can be stored, handled and transported efficiently.

Conversely, an expandable container has a main structure similar to the standard ISO container but also contains hinged wall, roof and floor panels that can be extended from one, two, three or four walls of the container to significantly increase the footprint and interior space. For example, an expandable Tricon has the footprint of a single Tricon when collapsed and can be expanded to have two, three, or four times larger footprint depending on the number of expansion sections. Moreover, other sizes and variations of standard sizes of containers (e.g., as described in International Organization for Standardization (ISO) 1496 standard, 1A, 1AA, 1AAA, 1C, 1CC, 1CX, 1D, etc.) are applicable to aspects of the present disclosures as described in greater detail herein.

There are multiple advantages attributable to expandable containers. For instance, the ability to compact multiple container's worth of volume into a reduced footprint (e.g., the size of a single container) makes the expandable container more efficient for travel when compared to traditional containers, especially over water, air, rough terrain, etc., where cargo space is a luxury for water vessels, aircraft, and land transportation vehicles.

Further, the ability to collapse an expandable container back into a compact footprint, move the collapsed expandable container to another location, and re-deploy the expandable container to its expanded form may allow mobile users (e.g., militaries, first responders, etc.) to more efficiently transport the expandable container along with a base camp or forward operating base as needed. During a deployment or tour, the base camp or forward operating base may be required to relocate multiple times. Having a container that can collapse, transport, and deploy can reduce the man hours spent on the relocation process.

While expandable containers are generally flexible in terms of how they are used, specialized tasks and needs can render generic containers less optimal or infeasible altogether. For instance, while a non-specialized expandable container can be reasonably adapted to become a kitchen unit by addition of a heating, ventilation, and air conditioning (HVAC) unit, specialized tasks such as preparing and cooking a wide array of food items necessitate consideration of factors such as air ventilation, managing food byproducts (e.g., grease fumes, liquid grease), managing electrical power, plumbing, and more. Accordingly, aspects of the present disclosure are directed toward addressing the above considerations and more as described in greater detail herein.

Expandable Field Kitchen

Now referring to FIG. 1, an expandable field kitchen 100 is disclosed. The expandable field kitchen 100 comprises an expandable intermodal container 102 and an access door 104 (e.g., disposed on a wall panel including an opening) that provides access to an interior portion of the expandable intermodal container 102. The access door 104 can be secured using various locks, latches, and fasteners such as vertical cross bars as shown in FIG. 1. In multiple embodiments, the access door 104 is an outward-articulating double-door.

In various embodiments, handles (“H”) for the access door 104 will be placed or sized such that the handles stay within an exterior vertical plane of a door frame and also within an allowable dimensional envelope to meet ISO specifications (e.g., the handles (H) do not extend beyond (or protrude) beyond dimensions of the expandable intermodal container 102).

One advantage of the outward-articulating double-door is even weight distribution across the expandable intermodal container 102, as opposed to a single door or panel, which may introduce excess stresses and/or loads to the expandable intermodal container 102 (e.g., at hinge points) when the single door is open.

In various embodiments, the access door 104 further comprises level gauges 106 that allow users of the expandable intermodal container 102 to quickly assess if the expandable intermodal container 102 is level (or at least on a level surface). In addition, multiple configurations of the expandable intermodal container 102 comprise pallet slots (“PS”, indicated by solid black arrows) that enable a materials handling vehicle (e.g., a forklift) to transport the expandable intermodal container 102.

FIGS. 2A-2B generally illustrate a Tricon embodiment of the expandable intermodal container 102 that comprises three expansion units labeled 108a, 108b, and 108c from left to right based the front view of FIG. 2A. Here, expansion units 108a and 108c are illustrated with a service door 110 (i.e., 110a and 110c respectively) with a low-profile door handle 112 (112a and 112c respectively), and expansion unit 108b is illustrated with a serving window 114.

In various embodiments, the low-profile door handle will be flush or recessed into a panel so as to allow easy folding and stowage. The specially designed door handle incorporates a secure locking mechanism to prevent unauthorized entry and spring-loaded handle. The entire handle is contained within the thickness of the door so the handle does not rub against other components of the expandable kitchen when stowed. In many embodiments, the thickness of the door is approximately 2.5 centimeters. The low-profile door handle is described in greater detail in reference to FIGS. 7-8 below.

Features such as the service door 110 and the serving window 114 can be used interchangeably (or combined) amongst the expansion units (108a-108c). Moreover, while FIGS. 2A-2B illustrate an embodiment with three expansion units (108a-108c), various embodiments of the expandable intermodal container 102 may only utilize one or two expansion units.

For clarity and conciseness, features and embodiments associated with the term “expansion unit” (e.g., 108a), while used in singular form in some contexts, are applicable to one or more expansion units in embodiments where more than one expansion unit is utilized.

Structurally, an expansion unit 108 (e.g., 108a) comprises an expansion floor panel 116, an expansion ceiling panel 118 that opposes the expansion floor panel 116, an expansion front panel 120 that couples to the expansion floor panel 116 and the expansion ceiling panel 118, a first expansion side panel 122 disposed orthogonally to the expansion floor panel 116 and the expansion ceiling panel 118, and a second expansion side panel 124 that opposes the first expansion side panel 122.

For a second expansion unit (e.g., 108b), the second expansion unit comprises a second expansion floor panel (analogous to the first expansion floor panel 116), a second expansion ceiling panel (analogous to the first expansion ceiling panel 118) that opposes the second expansion floor panel, a second expansion front panel (analogous to the first expansion front panel 120) that couples to the second expansion floor panel and the second expansion ceiling panel, a third expansion side panel (analogous to the first expansion side panel 122) disposed orthogonally to the second expansion floor panel and the second expansion ceiling panel, and a fourth expansion side panel (analogous to the second expansion floor panel 124) that opposes the third expansion side panel.

For a third expansion unit (e.g., expansion unit 108c), the third expansion unit comprises a third expansion floor panel (analogous to the first expansion floor panel 116), a third expansion ceiling panel (analogous to the first expansion ceiling panel 118) that opposes the third expansion floor panel, a third expansion front panel (analogous to the first expansion front panel 120) that couples to the third expansion floor panel and the third expansion ceiling panel, a third expansion side panel (analogous to the first expansion side panel 122) disposed orthogonally to the third expansion floor panel and the third expansion ceiling panel, and a fourth expansion side panel (analogous to the second expansion floor panel 124) that opposes the third expansion side panel.

Addition of a third expansion section specifically dedicated to the serving of the prepared food allows this function to be physically removed from the cooking/preparation areas and the cleaning areas allowing multiple functions to be performed at the same time. Three or more food service personnel can operate in the kitchen simultaneously without interfering with each other's work.

For each expansion unit 108, orientation of the expansion panels is based on which side of the expandable intermodal container 102 the expansion panels are deployed from. For example, the front panel 120b of expansion unit 108b is on the same panel as the service window. Conversely, the front panel 120a of expansion unit 108a is not on the same panel as the service door 110a.

The above example is for illustration purposes only. In various embodiments, the service door 110a of expansion panel 108a could be on the front panel 120a. The same applies for the various features (e.g., service door, service window, ports, etc.) described herein.

For clarity, while service doors (e.g., the service door 110a) are disclosed in conjunction with expansion units, service doors can also be integrated into expandable intermodal containers instead of (or in conjunction with) expansion units.

In various embodiments, the expansion ceiling panel 118 (or a portion thereof) extends beyond the expansion front panel 120 in at least one dimension to allow for rain runoff. Such a configuration is also useful for providing cover to users and patrons at the serving window 114 (e.g., for food services).

Further, each expansion panel (e.g., the expansion floor panel 116, the expansion ceiling panel 118, the expansion front panel 120, the first expansion side panel 122, the second expansion side panel 124, or a combination thereof) may be comprised of vacuum insulated panels (VIP(s)). A VIP is a panel having a form of thermal insulation comprising a gas-tight enclosure surrounding a rigid core (e.g., fumed porous silica or glass fiber), from which the air has been evacuated. VIPs generally provide higher insulation performance when compared to conventional insulation materials.

The various expansion panels herein can also include blown foam or other forms of insulation. External surfaces or “skins” of the various panels herein can be comprised of a composite skin (e.g., fiberglass, polymers, etc.), metal skins (e.g., metal skins such as zinc, copper, stainless steel, titanium, aluminum, metal composite materials, or combinations thereof), or combinations thereof.

Further examples of how the expansion unit 108 can be deployed/assembled, as well as VIP configurations (e.g., sandwich panel configurations), are disclosed in application Ser. No. 16/172,242 “CONTAINER PANEL AND STRUCTURES USING CONTAINER PANELS”, which is hereby incorporated by reference.

Moreover, various tools can be used to aid in deploying the expansion panels. For instance, a pogo stick or similar implement can be used to prop up the expansion ceiling panel 118, which allows a user to deploy the other expansion panels without having to personally hold the expansion ceiling panel 118 up.

In various embodiments, one or more expansion units 108 may further comprises one or more handles 126 to aid in deployment of the expansion unit 108 (e.g., pull handles). In preferred embodiments, the handles 126 are flush to, or recessed within, panels of the expansion unit 108 (e.g., the expansion front panel 120 as shown in FIG. 2) as to allow more compact storage of the expansion unit 108 when it is stowed in the expandable intermodal container 102.

In multiple implementations, the expandable field kitchen 100 further comprises vertically adjustable support jacks 128 that support a portion of the expansion floor panel 116. Since various embodiments of the expandable field kitchen 100 are mobile by design and function, it is possible that the expandable field kitchen 100 may be placed in an area where a ground surface is not adequately level. The vertically adjustable support jacks 128 can offset the unlevel ground, thereby creating a level environment for the expandable field kitchen 100.

In multiple embodiments, each vertically adjustable support jack 128 includes a base, a vertically adjusting member (e.g., a scissor member having a horizontal screw that raises or lowers a frame of hinged, rhombus-shaped linkages, etc.), and a guide plate. The guide plate is configured to catch and align the various expansion panels once the expansion panels have been deployed. The raised recess wall of the guide plate, which forms a corner geometry, thus conveniently aligns the corresponding mating panels

Now referring to FIG. 3, an embodiment of an interior 130 of the expandable intermodal container is illustrated. For reference, the interior 130 of FIG. 3 is spatially between the expansion units (108a-108c in FIGS. 2A and 2B). The expandable intermodal container 102 comprises an appliance utility port 132 disposed in the interior 130 of the expandable intermodal container (e.g., behind appliance as described in greater detail herein), a ceiling panel 134 and a floor panel 136.

Configuration of the appliance utility port 132 varies based on configurations within the expandable intermodal container. For example, the appliance utility port 132 can be a gas line (inlet/outlet), water lines (inlet/outlet), a power entry point to power appliances, an exhaust system (e.g., vent), and/or any utility port reasonably necessary to carry out the desired function of the expandable field kitchen 100.

In various embodiments, the expandable intermodal container comprises a recessed grease trap 138 under a portion the floor panel 136. For example, the recessed grease trap 138 can be implemented as a gravity trap that connects to a waste container (e.g., a bladder) or conduit that channels grease and waste away from the expandable intermodal container.

In this regard, the expandable intermodal container can support virtually any appliance so long as the appliance spatially fits within the expandable intermodal container. Example appliances include, but are not limited to ovens 140 (e.g., toaster ovens, conventional ovens, convection ovens, microwaves, etc.), grills/griddles 142, hood vents 144, and more.

In various embodiments, the ceiling panel 134 is implemented as a recessed ceiling cavity that allows users to install and/or store various components 146. The recessed ceiling cavity provides a dedicated space for components 146, which can be installed and remain in place irrespective of whether the expandable intermodal container is in a deployed or travel configuration. Thus, the components 146 do not need to be uninstalled and re-installed each time the expandable intermodal container is relocated.

Examples of components 146 include environmental controls (e.g., electrical control panels, HVAC components, etc.), appliance controls (e.g., grease filter/fan, exhaust system that channels cooking byproducts from an interior portion of the expandable field kitchen to an exterior portion of the expandable field kitchen, etc.), wiring for appliances or other portions of the expandable intermodal container 102 (e.g., concealed wiring that runs from the electrical control panel to one or more expansion units), etc.

FIG. 4 illustrates an example configuration of an interior of the expansion unit 108c. Here, the expansion floor panel 116c, an expansion ceiling panel 118c, and the expansion front panel 120c are provided for context.

In various embodiments, the expansion unit 108c comprises a heating, ventilation, and air conditioning (HVAC) port 150 that accepts removable HVAC unit 152. In multiple embodiments, a gasketed seal is disposed between the HVAC port 150 and the HVAC unit 152 when installed. Moreover, while the HVAC port 150 and HVAC unit 152 are disposed on the front expansion panel 120c in this illustration, they could be on other expansion panels in other configurations.

In addition to (or alternative to the HVAC unit 152), the expansion unit 108c may comprise exhaust systems and other mechanisms that correspond to appliances in use within the expansion unit 108c (e.g., hood vent for grill or stovetop).

In various embodiments, the expansion unit 108c comprises an embedded lighting unit 154 and concealed electrical wiring 156 that couples the embedded lighting unit 154 to an electrical control panel (see., e.g., component 146 in FIG. 3). In various embodiments, the embedded lighting unit 154 includes insulation (e.g., wiring insulation, insulation to shield against weather elements, etc.). Moreover, multiple embedded lighting units may be used (e.g., a first embedded lighting unit in expansion unit 108c and a second lighting unit in expansion unit 108a).

In further embodiments, the expansion unit 108c comprises a detachable sink unit 158. In multiple implementations, the detachable sink unit 158 comprises wheels 160 or other suitable transport mechanisms that allow the detachable sink unit 158 to be stowed in the expandable intermodal container 102 during transport and storage of the expandable field kitchen 100 (e.g., when the expansion unit 108c is not deployed).

Also illustrated in FIG. 4 is a floor coupler 170 that fastens the expansion unit 108c to the expandable intermodal container (e.g., couples a floor panel to an expansion floor panel). The floor coupler 170 comprises a hinge mechanism 172 with built in channels 174 that receive fasteners (e.g., screws, bolts, etc.), which allows the fasteners that are coupled to the expansion floor panel 116c to make slight adjustments to allow for better fitment between expansion unit 108c components as described herein. Further, the channels 174 within the floor coupler 170 provide enough “play” to allow the expansion floor panel 116c to shift in order to account for unlevel conditions.

Alternative acceptable hinges include bi-fold hinges, butt hinges, case hinges, conceal hinges, continuous hinges, flag hinges, slip joint hinges, overlay hinges, stop hinges, piano hinges, etc.

FIG. 5 illustrates a panel coupler 180 that allows various expansion panels to interconnect. Here, the panel coupler 180 is connecting the expansion floor panel 116c to the expansion front panel 120c. Here, the expansion floor panel 116c and the expansion front panel 120c are shown in a sandwich panel configuration.

In preferred embodiments, the panel coupler 180 is comprised of two separate parts (e.g., J-hooks) that link together. Here, one part is coupled to the expansion floor panel 116c, while the other part is coupled to the expansion front panel 120c. Specifically, the J-hooks uniformly attach the floor to the walls strengthening and reinforcing the floor and uniformly distributing the floor load to the walls which support the floor. Each part is highlighted by different line weights and dashes for clarity. In this regard, other geometries could be used to achieve the same or similar function.

Now referring to FIG. 6, which illustrates an example configuration of an interior of the expansion unit 108b, which includes the expansion floor panel 116b, the expansion ceiling panel 118b, the expansion front panel 120b, the first expansion side panel 122b, the second expansion side panel 124b (out of view, but indicated by directional arrow), and the serving window 114 disposed on the expansion front panel 120b. The serving window 114 allows users to pass food or other items from inside the expansion unit 108b to outside of the expansion unit 108b without physically exiting the expansion unit 108b.

Also illustrated in FIG. 6 are panel-to-panel fasteners 190. Suitable fasteners include latches, cam locks, lever locks, deadbolts, pad locks, recess locks (e.g., recessed catch point), mortise locks, etc. While many different types of fasteners can be used, preferred embodiments include over-center latches and J-hooks.

In practice, multiple types of fasteners may be used on one or more panels. For example, J-hooks (see e.g., FIG. 5) can be used to support floor panels (e.g., where an expansion floor panel engages an expansion front panel or expansion side panels), while the over center latches can be used to engage gaskets between various panels (e.g., between the expansion ceiling panel and expansion front panel) for a tighter fit between panels.

FIGS. 7-8 illustrate an embodiment of a low-profile door handle 700 to be used in the thinner doors of embodiments of expandable containers described herein. FIG. 7 illustrates the embodiment of the low-profile door handle 700 in an unlocked position. The low-profile door handle 700 includes a latch 702 that prevents a door 704 in which the low-profile door handle 700 is installed from opening when the latch 702 is engaged. Further, the low-profile door handle 700 includes a lever 706 coupled to a pivot point 710 and coupled to the latch 702. When a user applies force to the lever 706 in a direction away from an edge 712 of the door 704, the lever 706 also pulls the latch 702 into a recess 716 of the door handle 700 to allow the door 704 to open. In some embodiments, the lever 706 is biased such that when no force is applied to the lever 706, the lever 706 returns to the position shown in FIG. 7. In other embodiments, the user must apply force to return the lever 706 and latch 702 to the position of FIG. 7. Moreover, some embodiments of the low-profile door handle 700 include a locking mechanism 714, and as shown in FIG. 7, the low-profile door handle 700 is in an unlocked state. However, in FIG. 8, the locking mechanism 714 has been rotated such that a stop 716 of the low-profile door handle 700 prevents the lever 706 from traversing enough to allow the latch 702 to clear a door jamb (and strike plate); thus preventing the door from opening. The low-profile door handle 700 looks similar on both sides of the door, except that one side may also include a slot for a key to turn the locking mechanism.

If door is 3-4 inches (7-10 centimeters) thick, a traditional handle can be easily countersunk. However, as the door gets thinner (e.g., 2.5 centimeters), it gets harder to provide enough space for a user to grab and move the handle. Traditional door handles will not work with such a thin door without the handle sticking out. However, the low-profile door handle disclosed herein can be used in such thin doors. The lever of the low-profile door handle rotates such that it slides to open the door and there is no need for a large gap behind the lever.

Miscellaneous

While aspects of the present disclosure have been directed toward expandable field-kitchens, it is possible to substitute different appliances and equipment to render the expandable containers herein suitable for other applications. Such applications include adapting a container to function as a latrine, laundry, shower, living module, office or workshop. For example, the grease trap disclosed in various embodiments of the present disclosure could be repurposed or modified to as a plumbing for a toilet if the expandable container is repurposed to be a latrine, living quarters, laundry, and/or shower.

In another example of adapting the various containers to function as facilities such as a latrine or shower, a raised “false floor” that can be implemented such that plumbing and drain features would be contained inside the raised false floor, and by extension within the container, but be hidden from the users. In various implementations, the raised false floor is a second floor panel that is on top of a floor panel, wherein the raised false floor has an internal volume.

By way of example, an expandable intermodal container comprising a ceiling panel, a floor panel, and an appliance utility port, is being used as a latrine. Disposed above the floor panel is a raised false floor having an internal volume that can be used to house plumbing, waste, etc. Moreover, the raised false floor may further comprise an outlet to dump waste, purge contents of the false floor, etc.

Multiple types of power sources can be utilized to power the expandable field kitchens described herein. Suitable power sources include a electrical grid (e.g., microgrid), a battery, local power (e.g., a generator or an electrical cable that is connected to a local power grid), short power, a solar powered mechanism, and a wind powered mechanism.

Moreover, various embodiments of the expandable field kitchen may further comprise a spatial partition between the expandable intermodal container and an expansion unit. The spatial partition allows users to create two distinct zones wherein each zone can be adjusted to different thermal temperatures or prevent cross contamination of food items. In an example embodiment, the expandable intermodal container can be used to prepare food, while the expansion unit may be configured as a temporary refrigerator or freezer.

The spatial partition may be structurally configured in a variety of ways such as a bulkhead, an insulated material (e.g., insulated wall), an articulating panel, combinations thereof, etc.

The figures associated with respect to the expandable field kitchen illustrate a sampling of the various possible embodiments. Different combinations of the present disclosure herein can yield alternate embodiments. For example, while the above implementation had two expansion units, three or more expansion units may be used. In addition, additional serving windows and access doors (e.g., a second access door) can be implemented as needed.

The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the disclosure. As used herein, the singular forms “a”, “an” and “the” are intended to include the plural forms as well, unless the context clearly indicates otherwise. It will be further understood that the terms “comprises” and/or “comprising,” when used in this specification, specify the presence of stated features, integers, steps, operations, elements, and/or components, but do not preclude the presence or addition of one or more other features, integers, steps, operations, elements, components, and/or groups thereof.

The corresponding structures, materials, acts, and equivalents of all means or step plus function elements in the claims below are intended to include any structure, material, or act for performing the function in combination with other claimed elements as specifically claimed.
