ABSTRACT:
Releasable vertical and horizontal coupling of stacked shipping containers at their standard corner fittings, particularly in hard to reach areas in a block of containers, is provided by a connector having an extended planar base member, adjacent each end of the lower surface of the base member a manually-operated twist-lock for engagement with a corner fitting through the elongate orifice in the horizontal face thereof to form a horizontal coupling between a pair of lower containers in end-to-end alignment, in the middle of the upper surface of the base member a ridge with a ramp surface facing towards each end of the base member, and, adjacent each end of the upper surface of the base member and rising therefrom, a post having a side comprising an inclined surface direct towards a ramp surface and spaced apart from and substantially parallel thereto. The ramp surface interacts with a corner fitting as an upper container gravitates into stacked relationship with a lower container, thereby generating a horizontal component of relative movement between the containers to guide the corner fitting of the upper container into trapped relationship between the post and the ramp surface. During uncoupling, the inclined surface of the post functions in a like manner to guide the corner fitting out of trapping relationship.
