Container door securing mechanism
First Claim
1. A container having a loading opening including a pair of hinged doors swingable outwardly from closed to open position relative to said opening, said doors having vertical edge portions in the closed position being disposed in substantially contiguous relation, the improvement of a door closing and locking mechanism comprising;
- a vertical locking bar for each of said doors,hinge means having a vertical axis substantially parallel to said door coupling said locking bar and door for rotation of said locking bar about said vertical axis,said locking bar including upper and lower locking cam means,keeper means mounted on said container engageable by said locking cam means,said bars each having a parallelogram wall construction and having a generally rectangular configuration in horizontal cross section and including a flat surface portion abutably engageable with said door and said vertical axis being laterally offset from said flat surface portion, said bars including an apertured wall in the closed position of said bars being disposed substantially normal to the door to which it is connected,a slide bolt assembly on each door disposed laterally with respect to each said bar,said assembly including a bracket,a slide bolt slideably supported on said bracket and movable into engagement with said apertured wall of an adjacent bar for locking said bar against rotation in the closed position of said door.

Abstract
A container with hinged doors is provided with an improved locking bar arrangement including square and rectangular locking bars. The locking bars are rotated between open and locked positions by a locking pin or hinged handle which is removable from a bar interlock position to selectively engage apertured tubular gathering members provided on the bars for rotating them into the positions selected. Slide bolt assemblies also are movable into locking engaging position with the bars. The bars include camming means and keeper members are provided on the container which facilitate the opening and closing of the doors and which with the associated structure contributes to the total strength of the door assembly and in the stabilization of the container.
