Portable stacking containers locking device

A combination for stacking containers of the same size in a flat carrier of a predetermined size with the containers including corner fittings for receiving locking devices therein;

• (a) a plurality of angle members dimensioned to overlap the corner fittings of an upper and lower container when two containers are stacked;
• (b) each of said angle members include angular portions extending from one end thereof to facilitate the placing of one container over another when said angle members are in place;
• (c) said carrier comprising an elongated well therein formed by a floor surrounded by front, rear and a pair of side walls to receive said lower container therein and to restrict the movement of said lower container when the size of said bottom container is of substantially the same dimensions as said lower container;
• (d) a locking device connected to each of said angle members to lockingly engage one of said upper or lower containers whereby when said plurality of angle members are locked in place, they will maintain the relative positions of said upper and lower container with respect to each other,
• (e) said locking device including a lock member disposed to be inserted into the opening of a corner fitting of one of said containers and a turn bar adapted to be manually turned through a right angle to lock said lock member to said one container;
• (f) means in said carrier to provide a movable bulkhead normally stored in the floor of said flat carrier and adapted to be moved into a position to limit the movement of said containers when said container is dimensioned shorter than said floor;
• and
• (g) a connecting bar slidably mounted within said movable bulkhead at both ends thereof and adapted to be moved into side sill members forming parts of said side walls to provide longitudinal restraining means laterally across the floor of said flat carrier.
