Abstract: A twistlock for mounting and securing a container to a support including a socket and a plurality of operative components movable relative to the socket. The socket is supported within an opening of the support to locate an entry to a cavity within the socket at an upper surface. The operative components include a series of stacked members that are movable in concert in an extended position, and movable rotationally in a concert of movement or independently of one another. In this manner the members may be elevated, then positioned for receipt of the container, and, finally, one of the members may be moved to "lock" the container in position over the twistlock. There are stops for limiting movement longitudinally and rotationally and structure to permit independent movement of members rotationally.

Abstract: A connector for use in the securement of a first member, such as a cargo container, to a base support includes a base member, a post member extending from the base member in one direction and an attaching means for attaching the connector to the base support extending from the base member in the other direction. Restraining means provides vertical restraint to the container when the post member is positioned to extend into the opening of the web of the corner casting thereof and the container is restrained from movement in at least one horizontal direction. In one form, a restraining surface for the container is located on a cam pivotally mounted by the post member and in a second form, a restraining surface for the container is on the post member itself.
