The present disclosure provides a reversibly foldable freight container having a roof structure, a floor structure and sidewall structures. The reversibly foldable freight container further includes a front wall and a rear wall, where the front wall includes front wall corner posts, a front door hinge on at least one of the front wall corner posts and a front door joined to the front door hinge. The rear wall includes rear wall corner posts, a hinge on the rear wall corner posts and a rear wall door joined to the hinge, where the rear wall door can pivot on the hinge to extend adjacent an exterior surface of the sidewall structure or can pivot into the volume of the reversibly foldable freight container. In an unfolded state the reversibly foldable freight container has a predefined width measured at a predetermined point on each of two of the rear wall corner posts. A plurality of jointed members in the floor structure allows the reversibly foldable freight container in an unfolded state to move toward a folded state so that the predetermined points on the rear wall corner posts do not extend beyond the predefined width of the reversibly foldable freight container in the unfolded state.

1. A reversibly foldable freight container, comprising: a roof structure;a floor structure opposite the roof structure;sidewall structures between the floor structure and the roof structure, each of the sidewall structures having an exterior surface and an interior surface opposite the exterior surface;a front wall joined with the roof structure, the floor structure and the sidewall structures, the front wall including front wall corner posts, a front door hinge on at least one of the front wall corner posts and a front door joined to the front door hinge;a rear wall joined with the roof structure, the floor structure and the sidewall structures, where the roof structure, the floor structure, the interior surface of the sidewall structures and the rear wall define a volume of the reversibly foldable freight container, the rear wall including rear wall corner posts, a hinge on the rear wall corner posts and a rear wall door joined to the hinge, where the hinge can be locked to the rear wall corner posts in a first predetermined position so that the rear wall door can pivot on the hinge to extend adjacent the exterior surface of the sidewall structure or can be un-locked to the rear wall corner posts in a second predetermined position so that the rear wall door can pivot into the volume of the reversibly foldable freight container and extend adjacent the interior surface of the sidewall structure, and where in an unfolded state the reversibly foldable freight container has a predefined width measured at a predetermined point on each of two of the rear wall corner posts anda plurality of jointed members in the floor structure, where each of the jointed members includes: a first elongate section having a first surface defining a first oblong opening;a second elongate section having a second surface defining a second oblong opening; anda fastener passing through the first oblong opening and the second opening to connect the first elongate section and the second elongate section, where the first oblong opening and the second oblong opening move relative each other and the fastener as the jointed member transitions from a first predetermined state having a minimum overlap of the first oblong opening and the second oblong opening towards a second predetermined state having a maximum overlap of the first oblong opening and the second oblong opening relative the minimum overlap, where as the reversibly foldable freight container in an unfolded state moves toward a folded state the first oblong opening and the second oblong opening move relative each other and the fastener so that the predetermined points on the rear wall corner posts do not extend beyond the predefined width of the reversibly foldable freight container in the unfolded state. 2. The reversibly foldable freight container of claim 1, including a latch on the sidewall structures, where the latch engages and releasably holds the rear wall door adjacent the interior surface of the sidewall structure. 3. The reversibly foldable freight container of claim 1, including a locking rod mounted to the rear wall door, the locking rod having a first portion and a second portion joined to the first portion with a connection shaft, where the first portion and the second portion telescope relative the connection shaft to change a length of the locking rod. 4. The reversibly foldable freight container of claim 3, where the locking rod has a handle and each of the first portion and the second portion of the locking rod has a cam, where the cam engages and disengages a cam keeper mounted to the rear wall end frame of the reversibly foldable freight container as the handle turns the locking rod. 5. The reversibly foldable freight container of claim 4, where the locking rod travels past the rear wall end frame and the cam keeper as the rear door travels into the volume of the reversibly foldable freight container. 6. The reversibly foldable freight container of claim 1, where a hinge joins a first member end of each of the plurality of jointed members to a first bottom side rail and a second member end of each of the plurality of jointed members to a second bottom side rail. 7. The reversibly foldable freight container of claim 6, where the bottom side rail includes a beam box having surfaces defining an opening through which a lateral lock member can pass. 8. The reversibly foldable freight container of claim 7, where the lateral lock member passes through the beam box in the bottom side rail when the reversibly foldable freight container is in the folded state. 9. The reversibly foldable freight container of claim 1, where the roof structure includes a beam box having surfaces defining an opening through which a lateral lock member can pass. 10. The reversibly foldable freight container of claim 1, where the first elongate section includes a first abutment member and the second elongate section includes a second abutment member, where in the first predetermined state the first abutment member and the second abutment member are under a compressive force while the first surface defining the first oblong opening and the second surface defining the second oblong opening apply a shearing stress to the fastener. 11. The reversibly foldable freight container of claim 10, where each of the first surface and the second surface includes a first end and a second end opposite the first end, where the shearing stress in the first predetermined state is applied by the first end of both the first surface and the second surface. 12. The reversibly foldable freight container of claim 11, where each of the first end and the second end are in the shape of an arc, and where the first end of the first oblong opening and the second oblong opening form a circular shape when in the first predetermined state. 13. The reversibly foldable freight container of claim 10, where the first abutment member and the second abutment member define a first point of rotation for the first elongate section and the second elongate section; and the second end of both the first surface and the second surface, when positioned against the fastener, define a second point of rotation for the first abutment member and the second abutment member that is different than the first point of rotation. 14. The reversibly foldable freight container of claim 13, where the first elongate section and the second elongate section turn on the first point of rotation prior to turning on the second point of rotation as the jointed member transitions from the first predetermined state towards the second predetermined state. 15. The reversibly foldable freight container of claim 13, where the first end of each of the first surface and the second surface does not contact the fastener when the second end of both the first surface and the second surface are seated against the fastener. 16. The reversibly foldable freight container of claim 13, where the first elongate section includes a first member end opposite the first abutment member and the second elongate section includes a second member end opposite the second abutment member, where in the first predetermined state a distance between the first member end of the first elongate section and the second member end of the second elongate section provides a defined maximum length of the jointed member. 17.
