<p>The hinged door of a cargo container is provided with a locking mechanism contained wholly or mainly within the thickness of the door to draw the door into a closed and sealed position with respect to its surronding door frame. In one arrangement the mechanism has a tapered locking bolt that can be slid into a receiving recess in the surrounding door frame such that engagement of one face of the bolt taper with the socket urges the door into its fully closed and sealed position as the bolt is extended into the recess, and when the bolt is retracted engagement of the recess with the opposite face of the bolt taper breaks the door seal. In another arrangement the mechanism has a rotary pin projecting into a cam track to effect locking engagement.</p> |
