A modular panel system that can be readily assembled and configured into several types of structures that may be used both indoors and outdoors.

Disclosed are apparatus, systems, and methods, including a ground transport drive container comprising an outer container having a cuboid shape and comprising a plurality of fittings for securing the outer container to another apparatus; and a drive wheel assembly. The drive wheel assembly comprises one or more wheels and a deployment mechanism secured to the one or more wheels. An actuating member actuates the drive wheel assembly between a stowed configuration and one or more deployed configurations. In the stowed configuration, the drive wheel assembly is housed entirely within the outer container. In the one or more deployed configurations, the drive wheel assembly extends from the outer container.

A liquid storage tank with a storage unit has a flexible wall assembled from liquid-impermeable, flexible membrane sections. Due to their dimensions, these membrane sections give the liquid storage tank a predetermined operational shape when filled with the target amount of liquid. In the vertical operational position, this predetermined operational shape is drop-shaped, featuring an upper tip and a lower, bulged bottom area, where the tip is equipped with a supporting suspension for the storage unit, and a first liquid connection is provided in the bottom area. A method for manufacturing the liquid storage tank includes iterative calculations for the predetermined operational shape.

A modular container storage system includes multiple container units configured to be assembled to one another in an indefinite expanded state for enabling sheltered access to the stored items through a corridor enclosure, and in a compacted state for convenient transport and/or reduced storage space.

The present invention generally relates to a convertible, collapsible and reusable shipping crate. The crate is convertible in that the same base can used with extendable gates or fixed gates to ship equipment of differing heights, lengths, and wheel bases. At least one end of the crate may operate as a gate on a hinge for the loading and unloading of motorized vehicles. The hinge is comprised of a slotted plate on each side to lock the gates into place for loading and to raise the gates upright once loading is completed. The slotted plate positions the gates in an upright, locked position to carry all the weight on the upright beams of the gate, rather than the hinges, thereby allowing multiple crates to be stacked. The slotted plates also allow each of the two gates to collapse inward and flat on the base for stacking during return. The gates, optional cross braces, and slotted plates all contain removable pins as connectors so that no hand tools are required for setup, operation, and breakdown of the crate. The crate is reusable many times.

A modular container storage system includes multiple container units configured to be assembled to one another in an indefinite expanded state for enabling sheltered access to the stored items through a corridor enclosure, and in a compacted state for convenient transport and/or reduced storage space.

A pressure regulated volume exchange container includes a container body for holding both a first fluid and a second fluid, the container body defining a first volume portion and a second volume portion, a movable barrier disposed within the container body, the barrier configured to adjust the size of the first and second volume portions, an outlet in the container body through which the first fluid is extracted from the first volume portion, an inlet in the container body through which the second fluid is introduced into the second volume portion, and, an actuator mechanism operably connected to the movable barrier, the mechanism for moving the barrier within the container body in response to extraction of fluid from, or introduction of fluid to, the container body, wherein said actuator mechanism moves said movable barrier so as to maintain a predefined pressure within the first volume portion.

A container including first, second, and third side walls and an open end; a bottom wall coupled with the first, second, and third side walls; and a door pivotably coupled to the container and movable between a first position at which the door is spaced apart from the at least one open end and a second position at which the door closes the at least one open end. The container defines an interior volume of at least ten (10) cubic yards. At least one of the first, second, and third side walls includes a plurality of rectangular side panels releasably fastened together by mechanical fasteners. Each of the plurality of side panels defines a longitudinal axis. The longitudinal axes of each of the plurality of rectangular side panels are parallel with the bottom wall.

An expandable storage container comprises a floor and two longitudinal walls, each wall comprising at least one arm, with the wall connected through the arms to the floor so as to provide lateral extension of the longitudinal walls away from the floor. In certain embodiments, the arms are slideably or hingedly connected to the floor to provide lateral extension.
