Definitions

  • the present invention relates generally to expandable and retractable structures and specifically to expandable and retractable mobile units, such as trucks and trailers.
  • Expandable and retractable enclosures are useful in applications where more enclosed space is required than would be otherwise provided by a bus, coach, a nonexpandable/ nonretractable semitrailer, or a container.
  • Such applications include the use of mobile expandable/retractable enclosures as a classroom or other type of training facility, auditorium, medical clinic, command center, dispensary, mobile office, and exhibition room, and as a recreational and travel vehicle.
  • Expandable/retractable trailers have a number of design problems. Such a trailer should not have a small expansion volume which is inadequate for many applications.
  • many existing expandable/retractable trailers have roofs that fail to elevate and/or sides that fail to expand outwardly. The procedures to expand and/or retract the trailer are labor and time intensive and, therefore, costly.
  • Many expandable/retractable trailers require cumbersome structural members to be erected and/or the execution of preparatory construction work (such as providing a flat surface or foundation) .
  • Other trailers require a multiplicity of difficult and complex manual steps (such as folding out and/or rotating wall and floor panels and erecting internal and external support members) . When expanded, the trailer should be relatively stable and have a relatively large loading capacity.
  • Another objective is to provide an expandable/ retractable trailer, truck or other mobile unit that is simple and not labor intensive to expand and retract.
  • a related objective is to provide an expandable/retractable trailer, truck or other mobile unit that does not require cumbersome structural members to be erected, that does not require the execution of preparatory construction work before expansion, and/or that can be expanded and retracted automatically.
  • Yet another objective is to provide an expandable/ retractable trailer, truck or mobile unit that is relatively stable and has a large loading capacity when expanded.
  • the present invention realizes these and other objectives by providing a mobile unit, such as a trailer, truck, rail car and the like, that expands into an enclosed structure.
  • a mobile unit such as a trailer, truck, rail car and the like, that expands into an enclosed structure.
  • One embodiment of the mobile unit includes: (i) a base section providing a floor for the structure; (ii) a roof section located above the base section; (iii) a first connector between the roof section and the base section for moving the roof section in a vertical direction relative to the base section; (iv) a side extension that moves inwardly and outwardly relative to the base section; (v) a side panel depending from one of the roof and base sections and forming an upper surface of the side extension when the side extension is retracted and projected outwardly relative to the base section; and (vi) a second connector between the side panel and the side extension for rotating the side panel relative to the side extension when the side extension is retracted and projected outwardly relative to the base section.
  • the roof section can elevate relative to the base section by means of the first connector.
  • the first connector can be a plurality of actuators, with an actuator being positioned at each corner of the roof section.
  • the first connector can also include means for determining the elevation of the roof section relative to the base section to prevent under- or overelevation of the roof section.
  • the determining means can, for example, be a limiter switch.
  • the mobile unit can include a three-sided side extension that axially moves inwardly and outwardly like a bottomless drawer.
  • the side panel forms the roof of the side extension and a vertically stowed floor panel rotates outwardly and downwardly to form the floor of the side extension.
  • An extension panel is rotatably mounted on the side extension or side panel for filling the triangular gap that exists between the top of the side extension and the bottom of the side panel.
  • the first connector and side extension provide not only for a relatively large enclosed volume but also for a clear span interior. Few, if any, structural members are required within the enclosed space for integrity of the structure.
  • the procedure for expanding and retracting the unit is relatively straightforward and can be fully automated.
  • the automation of the process reduces the need for manual labor and/or a crane for unit expansion and retraction, and greatly simplifies unit expansion and retraction.
  • the second connector can be connected to the side panel by means of a guide means for guiding the second connector.
  • the guide means can be a channel, track, or the like positioned on the side panel or the side extension.
  • the second connector can be configured such that one member of the second connector rotates relative to another member of the connector as the second connector travels along the guide means.
  • the side panel can engage the base section such that, when the roof section is in a first vertical position, the side panel is in a locked position and, when the roof section is in a second vertical position, the side panel has freedom of movement.
  • the first and second vertical positions are different.
  • the side panel can include a projecting member received by a gap in the base section or vice versa.
  • the mobile unit can be a trailer having an axleless suspension system for the unit's wheels.
  • a storage unit can be positioned between the opposing sets of wheels for additional storage.
  • the unit can include a partition hinged about at least one of the roof section, base section and side extension.
  • the partition forms an interior wall of the enclosed structure.
  • the mobile unit can include another side extension located on the opposite side of the mobile unit from the above-noted side extension.
  • the side extensions can be offset from one another in the unit.
  • the mobile unit can include one or more outriggers.
  • the outrigger supports the side extension during axial movement thereof and has a base for shifting a portion of the weight of the side extension to a surface below the mobile unit.
  • the outrigger is rotatably connected to the base section such that the outrigger rotates in a plane that is substantially parallel to a plane of the base section.
  • the outrigger In a storage position, the outrigger is substantially parallel to a longitudinal axis of the base section and in a deployed mode is oriented transversely to the longitudinal axis.
  • the outrigger can have a guide means for guiding the side extension during axial movement thereof.
  • the mobile unit can perform self-leveling when deployed on an uneven and/or nonlevel surface.
  • the mobile unit includes determining means for determining the orientation of the base section relative to a horizontal plane and generating a signal indicating the orientation and leveling means for controlling the orientation of the base section relative to the horizontal plane in response to the signal from the determining means.
  • the determining means can be a mercury microswitch, pendum switch, and other suitable electronic or mechanical sensing devices.
  • the leveling means can be a plurality of actuators positioned at different locations on the base section.
  • the abilities of the mobile unit to expand into a large clear span interior and support heavy loads when expanded permit the mobile unit to house a full motion flight simulator.
  • the enclosed space has a sufficient volume to provide unobstructed freedom of movement for the full motion flight simulator.
  • the full motion flight simulator can be moved by a plurality hydraulic pistons in a variety of positions over a relatively large range of movement.
  • the mobile full motion flight simulator is advantageous to airline and airfreight companies, especially smaller companies, to meet FAA requirements regarding initial or upgrade crew training. Such training can be performed at lower hourly costs than training in an aircraft and, in some cases, than training in immobile full motion flight simulation facilities.
  • the present invention further includes a method for expanding and retracting a mobile unit.
  • the method includes the steps: (i) moving the roof section in a vertical direction; (ii) moving the side extension outwardly relative to the roof section; and (iii) rotating the side panel in a plane transverse to a longitudinal axis of the mobile unit.
