Claim:
A cargo container hold down arrangement for a cargo container having an underside equipped with a plurality of corner fittings for purposes of securing the cargo container to a substantially horizontal platform, each of said corner fittings comprising a locking opening and a bearing surface, each corner fitting being securable via a container securement device, each container securement device comprising: a shear block, the shear block having a front side, a top side, a back side, and a base portion, the base portion defining first and second force transmitting surfacing portions and a projecting portion, the first surfacing portion extending to either side of the base portion, the projecting portion being normal to a respective one of said bearing surfaces and comprising an internal chamber, the internal chamber being open at the front side, the second surfacing portion for engagement with the platform; an unpinned latch member, the latch member being pivotally mounted within the internal chamber for movement therein in a plane that is normally disposed relative to said front and back sides of said shear block, and about a pivot axis that is normal of such plane; the latch member including a nose portion having an upper cam surfacing means for installing engagement with the bearing surface, and an under cam surfacing means for removing engagement with the bearing surface; resilient means for biasing said latch member to dispose said nose portion thereof exteriorly of a shear block opening in said front side thereof when said cam surfacing means are not in use, said resilient means having a resilient member interposed between said latch member and said base portion opposite a tail portion of the latch member, means for effecting deflection of said latch member about said pivot axis to within the shear block on installing engagement of the bearing surface with the upper cam surfacing means, and means for effecting deflection of said latch member within the shear block on removing engagement from the bearing surface about a separate axis spaced frontwise from and parallel to said pivot axis; a link arm member, the link arm member comprising a hub portion and a cam cavity, the hub portion being pivotally mounted in said shear block for movement therein in a plane that is normally disposed relative to said latch member; and an indicator member, the indicator member comprising a clip end and a tubular end, the clip end being pivotally mounted to the hub portion via the cam cavity, the tubular end being translatable through the base portion via link arm member movement for providing a visual indication of latch member configuration.
