Abstract: A container coupling device is provided which can prevent displacement of an upper container and which is superior in durability. Upper and lower positioning protrusions provided integrally on top and bottom sides of a flange are inserted into engaging holes formed in corner fittings of upper and lower containers. The upper positioning protrusion is formed in the center of its top surface with a downwardly extending hole. A rotatable rotary shaft inserted in the hole has at its upper portion an engaging member which can engage the peripheral edge of the engaging hole of the corner fitting of the upper container. The upper and lower positioning protrusions are inserted in the engaging holes of the corner fittings of the upper and lower containers to prevent displacement of the upper and lower containers. The upper positioning protrusion, which is integral with the flange, bears a load due to inclination of the upper container. This improves durability of the container coupling device.

Abstract: A container coupling tool having a handle for disengaging top and bottom cones which is less likely to be turned in the wrong way. The coupling tool has a tool body having a first protrusion and a second protrusion and is formed with a bore extending therethrough from the top face of the first protrusion to the bottom face of the second protrusion. A rotary shaft is inserted in the bore. The tool body is further formed with a handle inserting hole in which is inserted a handle shaft having a lever at its outer end. A motion converter is provided between the handle shaft and the rotary shaft. By pushing up the lever, the top cone can be disengaged, and by pulling down the lever, the bottom cone can be disengaged. Thus, the lever cannot be turned in the wrong way by mistake. A stopper is inserted in a stopper inserting hole formed in a flange of the tool body.

Abstract: A container coupling tool including a tool body having a flange and positioning protrusions provided on top and bottom of the flange. The tool body is formed with a bore extending therethrough from the top surface of one of the protrusions to the bottom surface of the other. A rotary shaft is received in the bore and has at its top and bottom ends top and bottom cones. Also, handle is inserted in a hole formed in the tool body and is coupled to the rotary shaft. The tool body is formed with a stopper hole opening to the bottom of the flange and communicating with the bore. A stopper having a stopper pin is vertically movably inserted in the stopper hole.

Abstract: A method and apparatus are disclosed for loading a container with cars. A car loading apparatus includes a box shaped frame having a rectangular base frame, side frames, end frames and a top frame. It is assembled outside the container. Two cars are loaded onto the frame in two tiers, one on the base frame and the other on the top frame. The upper car is lashed to the frame to compress its suspension springs to such an extent that its top is lower than the upper frame of the entrance of the container. Rollers are mounted on the bottom of the box frame so that the frame thus loaded with two cars can be pushed into the container with human hands. Alternatively, the car-loading frame may be formed of a rectangular base frame and two gate-shaped gantry frames fixedly or removably mounted on the base frame.

Abstract: A container coupling device is disclosed for coupling upper and lower containers together in a simple and reliable manner to allow for reliable transport of stacked containers. The container coupling device includes a rotation restriction mechanism provided between a lower insertion shank and a lower engaging body. The lower engaging body is formed on upper and lower sides with tapered surfaces. A rotary shaft has a spring to bias the lower engaging body in a locking direction. The rotation restriction mechanism serves to temporarily prevent the lower engaging body from turning in the locking direction. This rotation restriction action can be released by additional turning torque in the locking direction. Such torque is produced when the upper or lower tapered surfaces engage with an engaging hole in the container. Upon release of the restriction mechanism, the spring will turn the lower engaging body toward the locking position.

Abstract: A deck fitting for securing a container on the deck of a ship including a socket member fixed to the deck and a coupling member removably attached to the socket member. The base portion of the coupling member has a pair of projections. The socket member has a circular hole and a flange formed at the periphery of the hole and partially cut away. The projections on the coupling member is inserted into under the flange of the socket member through the cutaway portion and then the coupling member is turned.

Abstract: A positioning cone for positioning containers stacked one upon another on a ship or the like engages the containers without the need of turning a separate external lever. This arrangement saves time required to clamp the containers to one another and ensures secure and accurate positioning work by the use of a cooperative latch and locking pin.
