ABSTRACT:
A cargo container hold down device that includes a shear block defining a base and housing therefore that is shaped so that the base forms a planar surfacing thereabout on which the cargo container corner fitting rests in the applied relation of the container relative to the supporting platform involved; the shear block housing pivotally mounts a latch device comprising a latch member that includes a nose portion having an upper cam surfacing for engagement by a correspondingly located container mounted corner fitting, and an under cam surfacing disposed for engagement by such correspondingly located container mounted corner fitting on removal of such container therefrom, the latch member being biased outwardly of the shear block housing to dispose the nose thereof over the container corner fitting supporting surface of the shear block housing, and including an element for withdrawing such latch member within the shear block housing about one pivot axis when the container is applied to the device, and an element for withdrawing such latch member within the shear block housing about a separate axis that is spaced from and parallels the first indicated pivot axis when the container is removed from such device, so as to achieve a smooth and easier loading of the container, and provide for increased force for cam positioning of the device latch member for container removal purposes.
