Description

Background of Invention

[0001] 1. Field of Invention

[0002] The present invention is directed to improvements in expandable shelter systems which can house diverse kinds of equipment (e.g. electronics, medical instruments, etc) for transport on conventional cargo systems and carrier vehicles to remote locations for rapid deployment.

[0003] 2. Brief Description of the State of Knowledge in the Art

[0004] Expandable ISO shelters for containing preconfigured electronic systems (e.g. command, control and communications C3 systems), as well as providing mobile field hospitals (i.e. medical treatment centers) are well known in the art.

[0005] Examples of such expandable shelter systems are disclosed in U.S. Pat. No. 5,815,988 to Molina; U.S. Pat. No. 5,658,032 to Gardner; U.S. Pat. No. 5,586,802 to Dewald, Jr. et al.; U.S. Pat. No. 4,546,578 to Behrmann; U.S. Pat. No. 4,854,094 to Clark; U.S. Pat. No. 4,603,518 to Fennes; and U.S. Pat. No. 3,107,116 to Meaker.

[0006] Examples of commercially available expandable shelters are offered by M. Schall GmbH & Co. KG, Germany, under the following product designation: Schall-Container-Systems Expandable SCS [1:2/1:3] for mobile command post applications, constructed according to ISO Standard or as a rolling-off container according to DIN 14505.

[0007] As described in its product brochures, the central part of the Expandable SCS is made of insulated and galvanized steel construction, and the expandable boxes are made from an insulated sandwich construction, with aluminum fittings. The heavy-weight version of the Expandable SCS is 9-times stackable, whereas the lightweight version of the unit is 4-times stackable. During its operating/deployment condition, the floors of the Expandable SCS are on the same level. The Expandable SCS is designed for various rapid and long-term applications, for operation on a carrier vehicle or on the ground. The expandable sections of the Expandable SCS are designed as closed boxes for an optimal overpressure tightness of the complete system. Due to its modular construction, he containers of the Expandable SCS can be adapted to the required application at hand and provided with doors, service cut outs, partition walls, etc. as required.

[0008] While the Expandable SCS offers many features and does suffer from a number of shortcomings and drawbacks.

[0009] In particular, the expandable sections of the Expandable SCS are realized as self-contained boxes with rigid flooring structures that nest within the central or main section of the Expandable SCS. In the single side expandable version of the SCS, the expandable box nests within the central section of the Expandable SCS. In the double side expandable version of the Expandable SCS, the expandable boxes nest within each other, and this sub-combination of boxes then nets within the central section of the Expandable SCS. Due to this prior art design, the Expandable SCS during its deployment/operating mode or condition, requires that the expandable boxes are automatically lowered to the same floor level as the central part (i.e. with no steps) using a leveling support system, which adds complexity and cost to the system design, and also provides an additional point of failure.

[0010] Furthermore, this prior art box nesting design of the expandable sections of the Expandable SCS prevents permanent mounting of equipment on the floor of the central section of the SCS during its transport mode. Consequently, equipment designated for installation on the floor of the central section of the Expandable SCS during the deployment mode, must be stored elsewhere within the central section of the Expandable SCS and then redeployed to the floor of the central station after the expandable section(s) have been moved to the deployment positions.

[0011] Another consequence of the prior art design employed by the Expandable SCS is that the expandable sections cannot be made to be substantially the same volume of the central section of the shelter system, maximizing on the expandability in volume of prior art shelter systems. This results in a non-optimal use of interior space with the expandable shelter system, and requires movement of (typically sensitive) equipment with the shelter system after deployment in the field, which is highly undesirable in demanding applications such as mobile C3 applications, and mobile field hospital applications.

[0012] Thus there is a great need in the art for an improved expandable shelter system that is free from the shortcomings and drawbacks of prior art shelter system designs.

Detailed Description of the Illustrative Embodiments of the Present Invention

[0096] Referring to the figures in the accompanying Drawings, the various illustrative embodiments of the expandable shelter system of the present invention will be described in great detail, wherein like elements will be indicated using like reference numerals.

[0097] In FIGS. 1 through 25, a single-side expandable shelter system according to the principles of the present invention is shown in great detail. Also, in FIGS. 26 through 35, a double-side expandable shelter system of the present invention is illustrated in great detail. In general, the expandable shelter system of the present invention has two distinct modes of configuration, namely: a transport mode in which the side expandable section(s) are completely nested within an (ISO-style) main or central shelter section; and a deployment (i.e. operating) mode or configuration in which the side expandable section are completely protracted from the main section.

[0098] In each of these embodiments of the present invention, the flooring structure of the side expandable section(s) is realized as a hinged flooring panel assembly consisting of at least two floor panels hinged together so that they can be stacked compactly in a vertically elongated direction when the corresponding side expandable section is retracted within the main/central shelter section of the expandable shelter system, in a nested manner, as to be completed contained therewithin its transport mode/configuration.

[0099] Several important benefits follow from this particular technical feature of the present invention, namely: equipment can be now permanently mounted on the floor structure of the central/main section of the shelter system; each expanding section of the expandable shelter system can now have an interior volume that is substantially the same as the interior volume of the central shelter section, thereby maximizing the total utilizable volume of the expandable shelter system in its deployment mode; electronic equipment can be permanently mounted to the upper half of the three walls of each expandable side section thereby allowing for permanent interconnection of this equipment; and complex floor leveling subsystem are completely eliminated, thereby reducing cost, complexity and points of failure in the expandable shelter system design of the present invention. These and other benefits of the present invention will become apparent as the various illustrative embodiments are described in the greater detail below.

[0100] In FIGS. 1 and 10, the single-side expandable shelter system of the present invention, constructed in accordance with ISO standards, 1 is shown arranged in its transport mode/configuration from different views, with its expandable section 2 nested inside the main shelter section 3 and its side door 4 arranged in its closed configuration during transport. As shown, the single side expandable shelter system 1 comprises: main shelter section 3 having (i) a floor structure 5, beneath which a replaceable full-length skid structure 6 is affixed thereto, (ii) a top panel 7, a front panel 8 with a front door having open and closed configurations, and (iii) first and second side panels 10 and 11, interconnected within a framework constructed from frame members 12A through 12H, in a conventional manner in accordance with ISO standards, to form a five-sided box-line container with an open side along its length dimension; (2) a single five sided expandable section 2 having a front wall panel 13, a top panel 14, and first and second side panels 15 and 16, and a foldable flooring assembly including first and second flooring sections 17A and 17B that hinged together at point 18 and with the bottom of the front wall panel 19 and the edge of the floor structure 20 of the main shelter section; and (3) a side expandable section support mechanism 21 including, in the illustrative embodiment, (a) a pair of hinged horizontally-extending expansion section support 22A and 22B which (i) are hingedly connected at one end to the bottom exterior of the main shelter section as shown, and their other ends by a pair of diagonally-extending cables 23A and 23B connected to the top portion of the main shelter section as shown.

[0101] During deployment, the horizontal side section support members 22A and 22B, and diagonal support members 23A and 23B, support the side expandable section when it is being projected out from within the interior volume of the main shelter section.

[0102] Optionally, a motor can be fixedly mounted to the bottom of the front side panel 13 of the side expansion section 2, and provided with gears that ride along guide tracks formed in support member 22A or 22B, and (i) pull the side expandable section out from the interior volume of the main section when the shelter system is being configured into its deployment mode, and (ii) push the side expandable section into from the interior volume of the main section, during the transport mode, as shown in FIGS. 11A through 14. The motor can be realized as a hand-operated winch device operated by manually turning a crank mechanism, or by a electric motor. In either case, the side expandable section support mechanism 21 can be modified as such to provide such automated or semi-automated transport of the side section into and out of the main shelter section during transitions between transport and deployment modes of operation.

[0103] In FIGS. 11 through 14, the shelter system is shown being reconfigured from its transport mode into its deployment/operating mode. During this configuration process, the side expandable section support mechanism 21 is pulled down into its operating configuration with horizontal support members 22A, 22B resting slightly above the ground surface. During this process, the foldable flooring assembly 14A, 14B unfolds and assumes its horizontal position, while being supported along its outer edges by support flanges provided along the perimeter of side wall panels 15 and 16 and front wall panel 13 of the side section 2 during the final phase of the deployment mode of configuration. After the side section 2 is slid out from the main shelter section 3, the horizontal and diagonal support members support the side section 2 during deployment.

[0104] In FIGS. 15 through 19, the expandable shelter system is shown from various views while its configured in its deployment mode. For purposes of illustration, all figure drawings sets forth in FIGS. 1 through 19 are shown without any interior equipment mounted within the expandable shelter system in order to help illustrate the construction of the system, and illustrate the simplicity and elegance of this inventive design.

[0105] In FIGS. 20A through 24, equipment of various kind (e.g. electronic equipment and rack and cabinet structures) 25 is shown mounted on both the interior wall surfaces and on the flooring structures within the expandable shelter system design to demonstrate the benefits that follow from the present invention. As shown in FIG. 20A, the expanded side section supports multiple cabinet structures 25 on the upper wall surfaces, below the vertical height of the folded flooring sections, while they are compactly stored away during the transport mode. Also, the floor structure of the main shelter section supports multiple cabinet structures, in accordance with a predetermined configuration of equipment and cabinet structures within the shelter system.

[0106] Referring now to FIGS. 26 through 35, the double-side expandable shelter system of the illustrative embodiment will be described in great detail in both its transport and deployment modes of configuration.

[0107] In FIGS. 26 and 30, the double-side expandable shelter system of the present invention, constructed in accordance with ISO standards, 30 is shown arranged in its transport mode/configuration from different views, with its expandable sections 31 and 32 are nested inside the main shelter section 33. As shown, the double side expandable shelter system 30 comprises: (1) main shelter section 3B having (i) a floor structure 35, beneath which a replaceable full-length skid structure is affixed thereto, (ii) a top panel 36, and (iii) first and second side panels 37 and 38, interconnected within a framework constructed from frame members described in connection with the single-side expandable shelter system, in a conventional manner in accordance with ISO standards, to form a four-sided box-line container with two opposing openings along its length dimension; (2) a pair of four-sided expandable sections 31 and 32, each having a front wall panel, a top panel, and first and second side panels, and a foldable flooring assembly including first and second flooring sections 7A and 7B that hinge together, as described above; and (3) a pair of side expandable section support mechanisms 21A and 21B, for supporting first and second side expandable sections 31 and 32, respectively, during the deployment mode of operation.

[0108] In FIGS. 31A through 35, the shelter system is shown configured in its deployment/operating mode. During this configuration process, the each side expandable section support mechanism 21A, 21B is pulled down into its operating configuration with horizontal support members 22A, 22B resting slightly above the ground surface. During the deployment process, the foldable flooring assembly 7 unfolds and assumes its horizontal position, while being supported along its outer edges by support flanges provided along the perimeter of side wall panels 7A and 7B and front wall panel of the side expandable section 31, 33 during the final phase of the deployment mode. After each side section is slid out from the main shelter section, the diagonal and horizontal support members support the load provided by expandable side sections 31 and 32.

[0109] In FIGS. 15 through 35, the expandable shelter system is shown without any interior equipment mounted within the expandable shelter system in order to help illustrate the construction of the system, and illustrate the simplicity and elegance of this inventive design. However, in view of FIGS. 20A through 24, the benefits and advantages gained by the design of the present invention are clear. Equipment of various kinds (e.g. electronic equipment and rack and cabinet structures) 25 can be permanently mounted on both the interior wall surfaces of the side expandable sections 31 and 32 above the height of the foldable flooring assemblies, and on the flooring structure of main shelter section.

[0110] As shown in FIG. 36, either the single or double side expandable shelter systems of the present invention can be arranged in their full deployment mode/configuration, while supported on a mobile carrier vehicle, as well as on the ground.

[0111] Also, as shown in FIG. 37, a plurality of single and/or double side expandable shelter systems of the present invention can be simply docked together to form a larger functioning unit 40, such as a command center, or medical hospital, for use in diverse field applications. Such inter-shelter docking operations can be achieved directly between door ports, and/or using flexible sluice (conduit-type) subsystems well known in the art.

[0112] While the wall panels of the expandable shelter system described above are preferably constructed by (i) welding vertical reinforcement members to sheets of aluminum, (ii) then placing insulating foam sheets between these members, and (iii) finally bonding a second sheet of aluminum thereto using epoxy adhesive, pressure and spot welding techniques—to form strong, yet very lightweight wall panels for constructing shelter wall sections—, it is understood that other alternative techniques may be used with excellent results in particular applications. Similarly, while the flooring structure of the main/central shelter section, as well the foldable flooring panels used in the side expandable section, are preferably made by welding aluminum frame members together using a reinforced architecture, then sandwiching such frame structures and insulating foam between sheet of aluminum, and bonding and welding the same using epoxy adhesive and spot welding techniques, other alternative methods of construction may also be used with excellent results in particular applications.

[0113] It is understood that the expandable shelter systems of the illustrative embodiments may be modified in a variety of ways which will become readily apparent to those skilled in the art of the present invention and having the benefit of the novel teachings disclosed herein. All such modifications and variations of the illustrative embodiments thereof shall be deemed to be within the scope and spirit of the present invention as defined by the Claims to Invention appended hereto.
