Abstract
The anti-theft device comprises essentially a movable vertical plate extending through an opening formed in the rain-strap overlying the doors of the container; this plate is adapted to drop by gravity to a position in which it is located behind lug extensions of the upper ends of the lock rods associated with each door panel to prevent the opening movement of the rods as long as the movable plate is not raised to a position overlying the lugs, this movable plate being rigid with a horizontal cover plate disposed on top of the container and prevented from being raised to a height sufficient for releasing the rods by another stacked container.
Claims4
In a container presenting hingedly mounted doors maintained in tight-sealing closure position by at least one rotating vertical rod provided at its ends with locking members engaging fixed stops of the door frame, an anti-theft locking device which comprises:
- a rain-strap opening provided in a front extension of the container roof in the vicinity of the upper end of said rotating vertical rod,
- a lug-shaped upper extension of the rotating vertical rod being placed in front of an upper portion of the door frame and providing, in the closure position of the rotating vertical rod, a free space in relation with said door frame, and
- a vertically movable plate engaging said rain-strap opening and moving downwards by gravity to lodge into the free space between said upper extension of the rotating vertical rod and said supper portion of the door frame,
- whereby the rotating vertical rod can be released to open the doors only when said movable plate has been raised sufficiently, this upward movement of the movable plate being normally prevented in any container supporting another, stacked container, by this other container.
