Door assembly for freight container

摘要

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.

主权项

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; and a 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.
