  • Patent number: 5797169
    Abstract: The invention relates to a coupling piece for the detachable connection of corner fittings of adjacent containers, especially of containers stacked one above the other on board ships.In order to reduce the manual effort involved in coupling together containers, semi-automatic coupling pieces are known which only need to be manually attached to one container and pre-locked. A full locking after the containers have been placed one on top of the other is effected automatically. Coupling pieces of this type require however, in many respects, a complex automatic actuating mechanism.In order to simplify the automatic actuating mechanism, a plurality of stop faces (43, 44 and 45) are provided, which are offset to one another on the locking bolt (21) and which can be brought alternately into a corresponding position to a stop face (54) on a spring-loaded ram (23).

  • Patent number: 5758391
    Abstract: Coupling piece for the detachable connection of corner fittings of containers stacked one above the other on board ships. Work to reduce the manual effort involved in coupling together the containers, often semi-automatically. The satisfactory operation of such coupling pieces depends essentially upon the observance of various operating specifics. If this is not done, malfunctions will result.The coupling piece according to the invention is intended to be able to be operated in a simple and error-free manner in order to avoid such malfunctions. To this end, an actuating device (22) for twisting the locking bolt (21) displaying crossbolts (32, 33) for connecting the containers is provided with a rope (49) displaying two pull cords (57, 58), which rope is connected centrally to the locking bolt (21). As a result of the two pull cords (57, 58), it is possible to twist the locking bolt (21) both clockwise and anti-clockwise.

  • Patent number: 5560088
    Abstract: A coupling piece includes an abutment and locking member which is shiftable relative to the abutment to allow for an automatic and reliable locking of the containers. The coupling pieces do not jam when the connection is released by means of slightly tilting the upper container. The coupling piece is particularly suitable for automatically locking and releasing tightly stowed containers, especially 20' containers. In an alternate embodiment, a coupling piece is shaped such that the entire coupling piece is shifted to a locking position when containers are placed on top of one another.

  • Patent number: 5297498
    Abstract: A bridge fitting (10) for anchoring containers, stacked especially on ship's decks or hatches, is provided with two operatively connected connecting pieces (12, 13) which are arranged at a variable distance to one another and which determine the effective length of the bridge fitting (10). These connecting pieces (12, 13) engage container corner fittings (11) of two adjacent containers and the effective length of the bridge fitting (10) can be adjusted by a steplike shiftability und lockability of at least one of the two connecting pieces (12, 13).

  • Patent number: 5141372
    Abstract: A coupling piece for releasably connecting corner fittings of adjacent containers, especially of containers stacked on top of one another on board of ships. The coupling piece includes a single-piece housing, having a locking bolt which is rotatable to different positions by an actuating device being mounted in the housing in a longitudinally shiftable manner. The single-piece housing is provided with a passage, through which an appropriately formed cross-bar of the locking bolt can be pushed while being in an assembly position.
