The present disclosure provides a hinge, a freight container that includes the hinge and a freight container that includes a locking rod and optionally the hinge. The hinge includes a locking pin, a first wing, a second wing and a first hinge pin that pivotally connects the first wing to the second wing. The hinge further includes a pair of hinge lugs each having a first set of surfaces defining openings through which a second hinge pin passes and at least one of the pair of hinge lugs having a surface defining an opening through which a locking pin reversibly travels. The locking rod is mounted to the door of the freight container, where the locking rod includes a cam that can move between a first predetermined position where the cam can engage the cam keeper and a second predetermined position where the cam is disengaged from the cam keeper and can travel past the end frame of the freight container and the cam keeper as the door travels into the volume of the freight container.

1. A 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, where the interior surface at least partially defines a volume of the freight container;an end frame joined with the roof structure, the floor structure and the sidewall structures, where the end frame has a door sill, a door header and a corner post between the door sill and the door header;a hinge on the corner post, the hinge having a locking pin, a first wing, a first hinge pin, a second hinge pin, and a second wing, where the first wing is fastened to the corner post, the second wing has a first planar portion with a first end and a second end and a second planar portion that extends perpendicular from the first end of the first planar portion, where the first hinge pin pivotally connects the first wing fastened to the corner post to the second end of the first planar portion;a pair of hinge lugs extending from the second planar portion, the hinge lugs each having a first set of surfaces defining openings through which the second hinge pin passes and at least one of the pair of hinge lugs having a surface defining an opening through which the locking pin reversibly travels;a pair of seating blocks fastened to the end frame to form a socket that receives and seats the second planar portion and at least a portion of the pair of hinge lugs, at least one of the pair of seating blocks having a surface defining an opening through which the locking pin travels reversibly to lock and un-lock the second wing from the corner post of the freight container; anda door joined to the pair of hinge lugs with the second hinge pin, where the door pivots on the second hinge pin relative the pair of hinge lugs when the hinge lugs are locked to the corner post of the freight container with the locking pin to allow the door to extend adjacent the exterior surface of the sidewall structure, and where the door and the second wing pivot on the first hinge pin when the hinge lugs are un-locked to the corner post of the freight container to allow the door to travel into the volume of the freight container and extend adjacent the interior surface of the sidewall structure. 2. The freight container of claim 1, where the pair of seating blocks includes a lower seating block and an upper seating block, and the pair of hinge lugs includes a lower hinge lug and an upper hinge lug, where the lower hinge lug seats on the lower seating block and the upper seating block has the surface defining the opening through which the locking pin travels through the opening of the pair of hinge lugs to lock and un-lock the second wing from the corner post of the freight container. 3. The freight container of claim 2, where the lower seating block includes a first surface on which the lower hinge lug seats a second surface substantially perpendicular to the first surface, and a third surface that slopes between the first surface and the second surface, where the lower hinge lug travels along the third surface as the second wing pivots around the first hinge pin relative the first wing. 4. The freight container of claim 2, where the upper seating block includes a first surface, a second surface substantially perpendicular to the first surface, and a third surface that slopes between the first surface and the second surface, where the second planar portion travels along the third surface as the second wing pivots around the first hinge pin relative the first wing. 5. The freight container of claim 1, where each of the lower hinge lug and the upper hinge lug include a surface defining an opening through which the locking pin travels, and each of the lower seating block and the upper seating block include a surface defining an opening through which the locking pin travels to lock and un-lock the second wing from the corner post of the freight container. 6. The freight container of claim 1, where the end frame includes a locking pin travel stop to limit a travel distance of the locking pin. 7. The freight container of claim 1, where the locking pin has a surface defining a structure on which a tool can be used to cause the locking pin to travel. 8. The freight container of claim 1, where the locking pin secures the hinge perpendicular to an axis of rotation of the second hinge pin. 9. The freight container of claim 1, where the door further includes an axle and a wheel, where the wheel is positioned between the door and the floor structure to support and guide the door as the door travels into the volume of the freight container. 10. The freight container of claim 1, including a latch on the sidewall structures, where the latch engages and releasably holds the door adjacent the interior surface of the sidewall structure. 11. The freight container of claim 1, including a locking rod mounted to the 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. 12. The freight container of claim 11, where the connection shaft has a polygonal cross-sectional shape. 13. The freight container of claim 11, 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 end frame of the freight container as the handle turns the locking rod. 14. The freight container of claim 13, where the locking rod travels past the end frame and the cam keeper as the door travels into the volume of the freight container. 15. The freight container of claim 11, where the door further includes stops that limit the degree of travel of the locking rod. 16. The freight container of claim 1, where the door includes: a locking rod with a handle and a cam, where the cam engages and disengages a cam keeper mounted to the end frame of the freight container as the handle turns the locking rod; andan anti-racking support extending away from a peripheral edge of the door, where the anti-racking support is directly adjacent the corner post when the cam is engaged with the cam keeper. 17. The freight container of claim 16, where the anti-racking support is directly adjacent both the hinge and the corner post when the cam is engaged with the cam keeper. 18. The freight container of claim 16, where the anti-racking support has a first surface that is directly adjacent the second wing of the hinge and a second surface parallel to the first surface that is directly adjacent a U-channel of the corner post when the cam is engaged with the cam keeper. 19. The freight container of claim 16, where the door further includes an anti-racking block having a tab and a slot to releasably receive the tab, and where the door of the freight container includes a first door and a second door, with the tab extending from the first door and the slot extending from the second door such that the tab seats completely within the slot when the cam of each of the first door and the second door are engaged with their respective cam keeper.
