Abstract: A mounting clamp for mounting a power supply to a thermal freight container wherein a stop is employed for insertion into the ISO castings of the thermal freight container and for clamping the power supply to the thermal freight container. A shaft with the stop attached on one end is supported by a base such that the shaft may rotate around and move along its longitudinal axis. A handle is attached to the shaft such that rotation of the handle causes the shaft to rotate which in turn causes the stop to rotate. A locking device is provided to engage the handle for locking the rotational movement of the handle in either a clamp or unclamp position. A fastening device cooperates with the shaft such that it controls the shaft's movement along its longitudinal axis.

Abstract: A horizontal connector interconnects adjacent ISO shipping containers. The connector has oppositely disposed locking arms which engage the inside surfaces of the respective container corner fittings. A push block assembly moves in a first direction to rotate the locking arm to engage the inside surface of a corner fitting, and then a reactive force from the surface engagement causes the push block to move in a second direction angularly disposed to the first direction to in turn cause push block surfaces to be frictionally engaged to lock the arm to the corner fitting. This locking action permits the containers to remain securely interconnected even when the connector and containers are subjected to excessive vibrations.

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.
