A novel logistics system is disclosed involving a roll container (100) with a base (110) and two elongated supports (120) that are supported by the base (110). The supports each have a plurality of individual slots (122) provided in a spaced apart configuration along the supports (120) for receiving a tab (133, 134) of a respective plurality of shelves (130) in a spaced apart configuration. The roll container may further include a folding mechanism between the base and the supports for turning the supports between an operational state and a folded state. In the operational state of the roll container the supports extend transversally in respect to the base. In the folded state of the roll container the supports extend parallel to the base.

Systems and methods are disclosed for foldable containers for manual and robotic use. In one embodiment, an example foldable container may include a first container wall, a second container wall configured to rotate outwards in a first direction with respect to the first container wall, and a bottom container platform configured to rotate outwards in a second direction with respect to the first container wall. The bottom container platform may include an automatic locking mechanism configured to engage with the second container wall when the foldable container is in an unfolded position, where the second direction is perpendicular to the first direction. Some embodiments may include a number of wheels. The foldable container may be configured to be transported using (i) the plurality of wheels via manual pushing, and (ii) robotic manipulation to lift and move the foldable container.

A collapsible cart may include a collapsible frame, a foldable shelf, and an interior support column. The collapsible frame includes a first frame portion and a second frame portion. The frame is configured to move between an open configuration and a collapsed configuration by relative translation between the first frame portion and the second frame portion. The foldable shelf extends between the first frame portion and the second frame portion. The foldable shelf is configured to fold to allow the frame to move from the open configuration to the collapsed configuration. The column transversely extends through a column slot defined by the foldable shelf. The cart further includes at least one column brace slidably coupling the frame to the column. The cart further includes at least one shelf brace slidably coupling the foldable shelf to the column.

Multi-level delivery systems and various apparatus associated therewith are presented. Multi-level delivery systems include a number of integrated, modular and interchangeable compactible elements that may work either alone or in conjunction with other such elements to allow for the deployment of a delivery system having a smaller overall spatial footprint when compared to comparable conventional delivery systems. Apparatus combining to form a delivery system may include one or more of: a compactible container cart, a compactible cart hauler or trailer, a propulsion means, and/or a maneuverability means. These elements or apparatus may be deployed in any combination, either together as an integrated system or with compatible conventional apparatus. In combination, delivery systems maximize space efficiency, and allow for adaption to any environment and scale.

A trolley configured for use to carry folding tables of a variety of sizes. The trolley includes a loading end, a trolley frame, and an extension gate adjustably connected to the trolley frame so as to be adjustable relative to the loading end of the trolley in a length direction of the trolley. The extension gate includes an elongate member slidingly disposed on the trolley frame and a rotatable portion that is foldable relative to the elongate member and lockable in an upright position by a lock. The rotatable portion may be positioned in an extended position from the loading end of the trolley, in a retracted position adjacent the loading end of the trolley, and in positions that are intermediate to the extended position and the retracted position. The elongate member may slide in a first direction to extend the rotatable portion away from the loading end of the trolley and in a second direction to retract the rotatable portion toward the loading end of the trolley.

A double-cross cart comprises two side wall assemblies, a front wall assembly, a rear wall assembly, a bottom frame assembly, a draw bar assembly and four wheels. A front end and a rear end of the bottom frame assembly are rotatably connected to a lower end of the front wall assembly and a lower end of the rear wall assembly, respectively. The draw bar assembly is rotatably connected to the rear wall assembly. The four wheels are arranged at the lower end of the front wall assembly and the lower end of the rear wall assembly. Each side wall assembly is a double-cross structure composed of two X-shaped connecting rods that are hinged together.

Disclosed are methods and apparatus for providing portable solar array support systems. Embodiments of the invention include an apparatus that holds four 60-cell rooftop-grade solar panels and folds up into a relatively small portable device that easily fits in a garage or shed. When open, the panels are displayed at near the nominal angle to the sun for the region. Adjustable angle supports are available in alternative embodiments. Embodiments of the foldable solar array system are constructed from steel components, and feature proprietary integrated hinges to minimize the size and complexity of the system. The hinges are specially-cut sections of steel angle iron that force a solid stop point in the open or closed positions. These may be 90° hinges on the panel arms and swing arms, and may be 180° hinges on panel-to-panel hinges. The panel-to-panel hinges also allow for an offset based on the thickness of the solar panels and make the solar panels lay flat when open and stack face to face when closed. The weight from the use of steel is useful to help stabilize the array in windy conditions. Additional weight and/or ground anchors can also be easily applied and are recommended for use in windy environments.

A trolley configured for use to carry folding tables of a variety of sizes. The trolley includes a loading end, a trolley frame, and an extension gate adjustably connected to the trolley frame so as to be adjustable relative to the loading end of the trolley in a length direction of the trolley. The extension gate includes an elongate member slidingly disposed on the trolley frame and a rotatable portion that is foldable relative to the elongate member and lockable in an upright position by a lock. The rotatable portion may be positioned in an extended position from the loading end of the trolley, in a retracted position adjacent the loading end of the trolley, and in positions that are intermediate to the extended position and the retracted position. The elongate member may slide in a first direction to extend the rotatable portion away from the loading end of the trolley and in a second direction to retract the rotatable portion toward the loading end of the trolley.

A collapsible wagon with a foldable/collapsible tailgate frame assembly coupled to a collapsible wagon frame assembly. The collapsible wagon frame assembly has a collapsible frame having a rear frame. The tailgate frame assembly has a tailgate platform having a pair of side rails, each pivotally connected to a corresponding bottom portion near the base of the rear frame, and a slider slidable along the corresponding side rails. A wheel support frame has ends each pivotally connected to a corresponding one of the side rails. A first connection member is pivotally connected to the slider and a wheel support frame, and a second connection member is pivotally connected to the slider and the rear frame. The tailgate frame assembly transitions between a collapsed state and an extended state with each slider sliding along a corresponding side rail.

A trolley configured for use to carry folding tables of a variety of sizes. The trolley includes a loading end, a trolley frame, and an extension gate adjustably connected to the trolley frame so as to be adjustable relative to the loading end of the trolley in a length direction of the trolley. The extension gate includes an elongate member slidingly disposed on the trolley frame and a rotatable portion that is foldable relative to the elongate member and lockable in an upright position by a lock.
