Definitions

  • the present invention relates to methods of securing freight containers.
  • freight containers are box type cases for efficiently and economically receiving and transporting cargo.
  • the freight containers have a standardized width of 8 feet.
  • the freight containers typically have lengths of 20 feet or 40 feet and heights of 8 feet, 8.5 feet or 9.5 feet.
  • the freight containers are mainly made of material, such as wood, plywood, steel, light alloys or aluminum, and are classified into various kinds of containers, for example, for general cargo, for liquid, for refrigeration, etc., according to the kind of cargo to be handled.
  • Such a freight container makes it possible to conveniently transport special cargo as well as general goods without requiring a separate outer packing process, thus reducing working time and expense. Furthermore, the freight container can prevent incidents such as the damage, loss or theft of cargo.

  • FIG. 2 is a view illustrating the freight container securing method according to the present invention. As shown in the drawing, the method of securing freight containers in a vertical direction using twistlocks is the same as that of the conventional art.
  • each layer of freight containers adjacent freight containers are coupled to and integrated with each other using a coupler 21 or a variable type coupling device 22.
  • This drawing shows a container securing example in which first through third layers of freight containers are integrated with each other.
  • freight containers which are placed in the lower portion of a stack of containers, are integrated with each other so that the lower part of the stack of containers forms a single body like a single container. Only two or three layers of containers from the top are secured by twistlocks. Therefore, the present invention can effectively withstand inclined loads and horizontal loads generated by rolling movement of the ship and by other types of movement thereof, thus ensuring stable transportation.
  • the present invention can effectively withstand inclined loads and horizontal loads generated by rolling movement of the ship and by other types of movement thereof, thus ensuring stable transportation.
  • the present invention makes it possible to stack freight containers to a relatively high position.

  • the bilateral coupler 21 includes an insert protrusion 31, which is provided at the medial position, and coupling protrusions 32, which are symmetrically provided on opposite sides of the insert protrusion 31.
  • the left coupling protrusion 32 is fitted into a front hole 1 Ia of a right corner fitting of the left container 10, and the right coupling protrusion 32 is fitted into a front hole 1 Ia of a left corner fitting of the right container 10.
  • a rotating latch 33 is provided on the end of each of the left and right coupling protrusions 32.
  • the left and right coupling protrusions 32 are oriented in one direction from the junction surface corresponding thereto. Therefore, after the process of stacking the freight containers using a crane has been completed, the rotating latches 33 are horizontally inserted into the front holes 11a, which are formed in the corner fittings. Subsequently, latch control levers 34, which are integrally rotated with the rotating latches 33, are rotated at 90°, so that, even if the ship excessively rolls, the coupler 21 is prevented from being removed from the corner fittings.
  • Fig. 4 is a view showing the coupling between a variable type coupling device 22 and the corner fittings 11 according to the present invention.
  • variable type coupling device 22 is coupled to side holes 1 Ib of the corner fittings 11 of the freight containers 10 and is constructed such that the length thereof can be varied to respond to a change in the gap between the freight containers.
  • the variable type coupling device 22 is used to couple the associated freight containers, which are placed on the two adjacent hatch covers, to each other.
  • Fig. 5 is a view showing the internal construction of the variable type coupling device 22 used in the freight container securing method according to the present invention.
  • the variable type coupling device 22 includes left and right movable protruding blocks 43, each of which has a pair of locking protrusions 43b which are fitted into the side holes 1 Ib of the corresponding corner fittings 11 of the adjacent containers, a double worm gear 44, which is operated to extend or retract the left and right movable protruding blocks, and a manual handle 42, which operates the double worm gear.
  • the variable type coupling device 22 further includes external screws 45, which are engaged in gear fashion with the worm gear 44 and are threadedly engaged with respective internal threads formed in the movable protruding blocks, and a casing 41 for supporting these components.
  • the left and right movable protruding blocks 43 which are separately provided, are coupled to each other through the external screws.
  • the locking protrusions 43b of the movable protruding blocks 43 are inserted into or removed from the respective side holes 1 Ib of the corresponding corner fittings 11.
  • the variable type coupling device serves to couple the stacks of containers, which are placed on the adjacent hatch covers, to each other to ensure structural continuity, thus increasing resistance to inclined loads and horizontal loads.
  • variable type coupling devices 22 are raised and installed using a ladder and a pulley device.
  • a safety cable is coupled between each variable type coupling device and the corresponding front hole 1 Ia of the corner fitting 11, such that, even if the coupling device 22 is undesirably removed by excessive movement of the ship, the container or the coupling device is prevented from falling onto the deck.
  • variable type coupling device 22 used in the freight container securing method according to the present invention will be explained herein below.
  • the coupling device 22 is disposed at a position such that the locking protrusions
  • the movable protruding blocks 43 are extracted from the casing 41, so that the locking protrusions of the opposite movable protruding block 43 are inserted into the respective side holes 1 Ib of the corresponding corner fitting 11. That is, the left movable protruding block 43 is coupled to the right corner fittings 11 of the left container 10, and the right movable protruding block 43 is coupled to the left corner fittings 11 of the right container 10.
  • variable type coupling device 22 the double worm gear 44, which is connected to the manual handle 42, rotates the external screws 45, which are symmetrically provided at positions above and below the worm gear 44, in opposite directions. Therefore, to move the movable protruding blocks 43 in opposite directions using the external screws 45, which are provided parallel to each other, threads are formed on left and right parts of each external screw 45 in opposite directions, and the threads of the upper external screw 45 are oriented in the direction opposite those of the lower external screw 45. According to the operational principle of the worm gear, the variable type coupling device 22 generates a relatively large force in the direction in which the left and right containers move away from each other, thus the coupling device 22 is reliably locked to the containers.
  • a securing means is used to provide horizontal structural continuity to stacks of containers vertically coupled to each other, thus reliably maintaining the secured state of the stacks of containers, such that the containers can effectively withstand inclined loads and horizontal loads using their own strength. Therefore, the present invention can reduce deformation of and damage to the containers, and makes it possible to stack the containers higher, thus enhancing economic profitability.
